In the above, the components are described in terms of their positional relationship.

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments.

The present invention provides a net drinker. Referring to Figures 14 and 15, the net drinker includes a water treatment module 200 and a heating module 500, and the heating module 500 includes an instant device 510 for instantaneous heating of the liquid and The constant temperature hot water tank 520 is heated to a preset heat temperature value and is thermostatically protected, and the normal water flow path CW and heat are arranged in parallel between the pure water outlet of the water treatment module 200 and the hot water inlet of the instant heat device 510. The tank flow path RG is provided with a constant temperature hot tank 520 in the hot tank flow path RG. Specifically, the net drink machine can be a desktop net drink machine, or a vertical or horizontal net drink machine, and in particular can also be an embedded net drink machine. Among them, since the embedded net drink machine can be completely embedded in the cabinet or the wall, and thus formed into a coordinated whole with the whole kitchen, it is increasingly favored by consumers and more and more popular.

In the present technical solution, a juxtaposed normal temperature flow path CW and a hot tank flow path RG are disposed between the pure water outlet of the water treatment module 200 and the hot water inlet of the instant heat device 510, and the constant temperature hot tank 520 is disposed at In the hot tank flow path RG, when the user needs to take the normal temperature liquid, the net drink machine can directly output the normal temperature liquid of the water treatment module 200 through the normal temperature flow path CW; when the liquid temperature required by the user is between normal temperature and preheating When the temperature between the temperature values is set, the net drinker can transport the normal temperature liquid of the water treatment module 200 to the instant heat device 510 through the normal temperature flow path CW, and then flow out after the heat device 510 is heated to the target liquid temperature; When the liquid temperature is a preset heat temperature value, the net drinker can output the constant temperature liquid stored in the constant temperature hot tank 520 through the hot tank flow path RG; when the temperature of the liquid to be taken by the user is greater than the preset heat temperature value, the net The drinking machine can transport the constant temperature liquid of the constant temperature hot tank 520 to the instant heat device 510 through the hot tank flow path RG, and then flow out after the heat device 510 is heated to the target liquid temperature. In this way, while the liquids of different temperatures are output more accurately, the output liquid can be made to have a suitable flow rate, so that the user's operation can be greatly improved, and the user experience can be greatly improved.

Preferably, referring to Fig. 15, a normal temperature water pump 530 is provided in the normal temperature flow path CW, and a hot water pump 540 is provided at the hot water outlet of the constant temperature hot tank 520. Of course, the normal temperature liquid from the water treatment module 200 can be sent to the instant heat pump 510, which can be a normal temperature water pump 530, and can also be other power devices. Similarly, the constant temperature liquid in the constant temperature hot tank 520 is sent to the instant heat device. The 510 can be a hot water pump 540, and can also be other power devices, and details are not described herein.

In addition, the net drinker further includes a controller, and the controller is configured to:

First, the normal temperature liquid of the water treatment module 200 is introduced into the constant temperature heating tank 520 to heat the normal temperature liquid to a preset heat temperature value and to be kept at a constant temperature;

Receiving the target liquid temperature, comparing the target liquid temperature with the preset normal temperature value and the preset thermal temperature value, respectively, and selecting a corresponding heating working mode of the heating module 500 according to the comparison signal;

Wherein, when the target liquid temperature is equal to the preset normal temperature value, the first heating operation mode is selected, and the normal temperature water pump 530 is controlled to operate to output the normal temperature liquid of the water treatment module 200 through the normal temperature flow channel CW; or

When the target liquid temperature is between the preset normal temperature value and the preset thermal temperature value, the second heating operation mode is selected, and the normal temperature water pump 530 is controlled to operate to send the normal temperature liquid of the water treatment module 200 through the normal temperature flow channel CW to The heat device 510 simultaneously controls the heat device 510 to operate to heat the normal temperature liquid to the target liquid temperature and then flows out; or

When the target liquid temperature is equal to the preset heat temperature value, the third heating operation mode is selected, and the hot water pump 540 is controlled to operate to output the constant temperature liquid held in the constant temperature hot tank 520 through the hot tank flow path RG; or

When the target liquid temperature is higher than the preset heat temperature value, the fourth heating operation mode is selected, and the hot water pump 540 is controlled to operate to transfer the constant temperature liquid of the constant temperature hot tank 520 to the instant heat device 510 through the hot tank flow path RG. The control heat device 510 operates to heat the constant temperature liquid to the target liquid temperature and then to flow out.

Specifically, the liquid temperature required by the user is roughly divided into four application scenarios, that is, the liquid temperature required by the user is a preset normal temperature value, and the liquid temperature required by the user is between the preset normal temperature value and the preset thermal temperature value, and the user The required liquid temperature is the preset application temperature temperature and the liquid temperature required by the user is greater than the preset thermal temperature value. Thus, the user can give the corresponding target liquid temperature to the net drinker according to the liquid temperature required by the user. Then, the target liquid temperature is compared with the preset normal temperature value and the preset hot temperature value by the controller (that is, which of the four application scenarios is determined by the target liquid temperature), and finally the selection signal is selected according to the comparison signal. The corresponding heating operation mode of the heat module 500 can not only satisfy the user's drinking demand for different temperature liquids, but also facilitate the user's use operation, and can greatly improve the user's use experience. In addition, compared with the user's manual adjustment of the liquid temperature, the temperature of the liquid obtained by giving the target liquid temperature to the controller and then the corresponding heating working mode is more precise and the operation is more convenient. Wherein, the target liquid temperature may be an exact temperature value or a temperature range; and the preset normal temperature value is generally a predetermined value, such as 25 ° C; specifically, the target liquid temperature and the preset normal temperature value may be actual Depending on the process requirements, no special restrictions are imposed here.

Specifically, the thermal heating power of the thermal device 510 generally has an upper limit value (generally not more than 2100 W) due to limitation of household electricity consumption. Thus, if only the thermal device 510 is used, the normal temperature liquid from the water treatment module 200 is used. When heated to boiling, the amount of liquid that can be handled per unit time is small (usually only about 300 ml), so that the boiling water flows out slowly from the water outlet 900 of the net drinker, giving the user a bad experience. In view of this, when the temperature of the received target liquid is high (for example, 95 ° C), the fourth heating operation mode is selected correspondingly, and the constant temperature liquid of the constant temperature hot pot 520 is sent to the instant heat device 510 and heated to the target liquid temperature and then flows out. That is, the heat inlet device 510 is no longer a normal temperature liquid, but a constant temperature liquid having a certain initial temperature, so that the amount of liquid that the heat treatment device 510 can handle in a unit time can be greatly improved, thereby making the water outlet The flow rate of the liquid flowing out of the mouth 900 is suitable, which is beneficial to enhance the user experience. It should be noted that the liquid heated by the hot device 510 is divided into two temperature intervals by setting the constant temperature hot pot 520, that is, the preset normal temperature value to the preset heat temperature value, the preset heat temperature value to the liquid boiling temperature, Thus, when the received target liquid temperature is relatively low (ie, between the preset normal temperature value and the preset thermal temperature value), the second heating operation mode is selected correspondingly, and the normal temperature liquid of the water treatment module 200 is delivered to That is, the heat device 510 flows out after being heated to the target liquid temperature. Wherein, since the target liquid temperature is low (ie, the difference between the target liquid temperature and the preset normal temperature value is small), the amount of liquid that the heat device 510 can handle in a unit time is relatively large, prompting the net drink. The flow rate of the liquid output by the machine is suitable.

In addition, when the target liquid temperature is equal to the preset normal temperature value, the first heating operation mode is selected correspondingly, the normal temperature liquid of the water treatment module 200 is directly output; and when the target liquid temperature is equal to the preset thermal temperature value, the third heating is selected accordingly. In the working mode, the constant temperature liquid stored in the constant temperature hot pot 520 is directly output; in these two working modes, since the liquid is not processed, the liquid can be outputted from the net drinking machine more quickly, and the user feels used. better.

Specifically, the liquid heating control method in the present case can make the water discharge flow rate of the net drinker not less than 600 ml/min. Further, the water flow rate of the net drinker can also reach not less than 700 ml/min. In this way, the liquid flow rate outputted by the net drinker is more suitable, so that the user has a better experience when receiving water.

In addition, in the present invention, the time interval between the given time node giving the target liquid temperature and the water outlet time node of the liquid outlet 900 of the net drinker flowing out of the target liquid temperature may be made no more than 1 second, thus facilitating The user immediately takes the liquid with the target liquid temperature, which is beneficial to enhance the user experience.

Preferably, the preset heat temperature value is not to be less than 45 ° C and not more than 65 ° C. It is understood that the preset thermal temperature value is preferably within the range, whether the target liquid temperature is between the preset normal temperature value and the preset thermal temperature value, or whether the target liquid temperature is higher than the preset thermal temperature. In the case of the value, the instant heat device 510 can process a sufficient amount of liquid per unit time, so that the liquid flow rate output from the net drinker is more suitable, which is more favorable for improving the user experience. In addition, setting the preset heat temperature value between 45 ° C and 65 ° C not only can quickly brew the brewing medium (such as honey), but also does not damage the beneficial ingredients in the brewing medium. The user uses the temperature more commonly used. Therefore, setting the preset thermal temperature value to not less than 45 ° C and not more than 65 ° C is also convenient for the user to use.

In addition, the hot pot pump 540 and the normal temperature pump 530 are variable power pumps. And/or, that is, the thermal device 510 is a constant power heating device, that is, the heating power of the thermal heating element in the thermal device 510 is not less than 1500 W and not more than 2500 W. Preferably, the heating power of the heating element should be between 1600 W and 2000 W. Of course, in the net drink machine, the hot pot pump 540 and the normal temperature pump 530 are both constant power pumps, and the heat unit 510 is a variable power heating device.

Preferably, an influent temperature sensing element is provided at the hot water inlet of the thermal device 510 to sense the temperature of the liquid flowing into the thermal device 510; and/or at the hot water outlet of the thermal device 510 An outlet temperature sensing element for sensing the temperature of the liquid flowing out of the thermal device 510, so that the temperature of the liquid at the hot water inlet and/or the hot water outlet can be sensed in real time, facilitating heating of the net drinker The working mode is finely adjusted.

Specifically, in winter, the ambient temperature is much lower than the preset normal temperature value (for example, 25 ° C). At this time, the temperature of the normal temperature liquid from the water treatment module 200 is also much lower than the preset normal temperature value, if not the normal temperature liquid The heat treatment is directly output for the user to drink, and the user will have the illusion of drinking cold water when drinking, and the liquid temperature of the straight drink is low, which will bring a poor drinking experience to the user, especially For female users of the physiological period. In view of this, the controller is further configured to: in the first heating operation mode, when the water inlet temperature detected by the inlet water sensing element is lower than the preset normal temperature value, the control startup heat device 510 heats the liquid to the pre-heating Set at room temperature and then flow out.

In order to make the difference between the output liquid temperature and the target liquid temperature small, to ensure that the temperature of the liquid flowing into the user's liquid cup is close to the given target liquid temperature, the controller is further configured to: in the second heating mode, The outlet water temperature detected by the outlet temperature sensing element is respectively compared with the target temperature upper threshold and the target temperature lower threshold, and when the outlet water temperature is higher than the target temperature upper threshold, the operating power of the normal temperature pump 530 is controlled to be increased, and the outlet temperature is When the threshold value is lower than the target temperature, the operating power of the normal temperature water pump 530 is controlled to be lowered; and in the fourth heating operation mode, the water temperature detected by the water temperature sensing element is respectively compared with the target temperature upper threshold and the target temperature lower threshold In comparison, when the outlet water temperature is higher than the target temperature upper threshold, the operating power of the hot tank pump 540 is controlled to be increased, and when the outlet water temperature is lower than the target temperature lower threshold, the operating power of the hot tank pump 540 is controlled to be lowered.

Wherein, the target temperature upper threshold should not be greater than 101% of the target liquid temperature, and the target temperature should be not less than 99% of the target liquid temperature, so that the temperature of the liquid flowing out of the water outlet 900 can be strictly controlled, which is beneficial to enhance the user's Use experience. Specifically, if the target liquid temperature to be administered is 50 ° C, the threshold value at the target temperature should be no more than 50.5 ° C, and the threshold value at the target temperature should be not less than 49.5 ° C.

In addition, the outer peripheral wall of the constant temperature hot tank 520 is surrounded by a hot tank heating element to heat the liquid in the constant temperature hot tank 520 to a preset heat temperature value, and to reduce the heat loss of the hot tank heating element and the constant temperature hot tank 520, The hot tank heating element is also covered with a thermal tank insulation layer.

Preferably, the hot pot volume of the constant temperature hot tank 520 is not less than 400 ml and not more than 800 ml, so that the user's normal drinking water demand can be ensured, and the space required for the constant temperature hot tank 520 in the cabinet 100 is also small. This makes the net drinker more compact and compact. Further, the heating power of the hot tank heating element is not less than 600 W and not more than 1000 W, so that when the constant temperature liquid in the constant temperature hot pot 520 is used up, it takes only a short time (for example, about 2 minutes), and the hot tank is heated. The component can heat the normal temperature liquid in the constant temperature hot pot 520 to a preset heat temperature value, which is convenient for the user to access again.

Specifically, the heating element may be an electric heating tube, an electric heating film, a thick film, a coil disk or a PTC thermistor, etc., as long as the heating element can heat the liquid flowing into the thermal device 510; The heating tank heating element for heating the liquid in the constant temperature hot tank 520 may be an electric heating tube, or may be another heating element such as an electric heating film, a thick film, a coil disk or a PTC thermistor, and is no longer a case here. Lift. Further, the thermal insulation layer coated on the outer surface of the hot pot heating element may be selected from a heat insulating material layer such as a ceramic layer, a silicate fiber layer, a porous coating layer or an aluminum silicate layer.

In addition, when the user does not use the net drinker for a long period of time, the constant temperature liquid stored in the constant temperature hot pot 520 gradually breeds bacteria and deteriorates, and if it is consumed, it will damage the user's body, and therefore, preferably at the bottom of the constant temperature hot pot 520. A hot tank drain pipe 521 is connected to the end for draining the liquid in the constant temperature hot tank 520. Referring to FIG. 15, a drain solenoid valve 522 is further provided in the hot tank drain pipe 521 for the convenience of the user.

Preferably, referring to Fig. 15, the water treatment module 200 includes a pure water tank 210, so that pure water filtered through the filter layer can be stored in the pure water tank 210 to meet the demand of the user for large throughput. Further, in order to enable the pure water carried in the pure water tank 210 to flow autonomously to the constant temperature hot tank 520, the water tank outlet of the pure water tank 210 is connected to the hot tank inlet of the constant temperature hot tank 520, and the height of the water tank outlet is set. Not lower than the set height of the hot water inlet. Thus, when the drain solenoid valve 522 is opened, the deteriorated water in the pure water tank 210 and the constant temperature hot tank 520 can be discharged outside the machine through the hot tank drain pipe 521.

In addition, the net drinker further includes an external display panel, and the display panel is provided with a plurality of water temperature buttons corresponding to different target liquid temperatures, so that the user can select the water temperature button provided on the display panel to give the target liquid. The temperature is convenient for the user to use.

The present invention provides a water outlet 900. Referring to Figures 23 to 25, the water outlet 900 includes a top tube 910 formed with a top tube lumen that expands in a water discharge direction, and a bottom tube 920 that is connected to the bottom end of the top tube. The bottom end of the bottom tube is formed with a water outlet 921; and a manifold 930 is built in the lumen of the bottom tube and is formed with a confluent lumen which is reduced in diameter in the direction of water discharge.

The water outlet 900 is applied to the net drink machine. Referring to FIG. 14 and FIG. 23, the net drink machine is provided with at least a boiling water outlet pipe and a normal temperature water outlet pipe, and the hot water outlet pipe and the normal temperature water outlet pipe are connected to the water outlet 900. Jacking tube 910.

In the present technical solution, a liquid with a certain pressure (such as boiling water, normal temperature water, etc.) flows into the top tube 910 of the water outlet 900, and the top tube lumen is arranged to expand in the direction of the water discharge, so that the liquid from the top tube 910 The water inlet 913 first opens into the pipe cavity of the smaller pipe diameter, and then flows into the pipe pipe cavity of the larger pipe diameter, so that the liquid pressure suddenly becomes smaller at the expansion pipe diameter of the pipe pipe cavity, that is, Due to the expanded diameter design of the pipe jacking, the liquid flowing into the water outlet 900 can be depressurized at the expanded diameter of the pipe jacking chamber, thereby performing vapor-liquid separation; wherein the separated water vapor obtained by vapor-liquid separation can be The turbulent flow is formed in the lumen of the capping tube and can impact the inner peripheral wall of the lumen of the capping tube multiple times, so that the separated water vapor can condense and accumulate on the inner peripheral wall of the lumen of the capping tube, and then down the inner peripheral wall of the lumen of the capping tube Inflow into the manifold cavity, in this way, it is beneficial to avoid forming a large amount of white mist at the water outlet 921 of the water outlet 900 and drifting upward, which not only can greatly improve the sensory experience when the user operates, but also can effectively prevent the floating water vapor (such as The boiling water is separated by vapor-liquid separation. High temperature water vapor) burns user, it will help improve the safety factor of the user, thereby enhancing the user experience. In addition, the separated liquid obtained by vapor-liquid separation can also hit the inner peripheral wall of the top tube lumen multiple times, and then smoothly flow down into the manifold cavity along the inner peripheral wall of the top tube lumen, so that the top tube The lumen also has a stabilizing effect.

Preferably, referring to FIGS. 23 to 25, the top pipe 910 includes a vertically disposed initial inlet pipe 911 and a vertically disposed vapor-liquid separation pipe 912, and the initial inlet pipe 911 is connected to the top peripheral wall of the vapor-liquid separation pipe 912, the initial inlet pipe The pipe diameter of the 911 is smaller than the pipe diameter of the vapor-liquid separation pipe 912. Therefore, when a liquid with a certain pressure flows into the vapor-liquid separation pipe 912 through the initial inlet pipe 911, the liquid can be released in the vapor-liquid separation pipe 912, and further Perform vapor-liquid separation. Of course, the top tube 910 may have other suitable structures in addition to the above structure, as long as the tube lumen is formed as an expanded diameter structure along the water discharge direction.

Further, the vertical height of the vapor-liquid separation tube 912 is increased, that is, the horizontal setting position of the water inlet 913 of the water outlet 900 is increased, so that the horizontal setting position of the water inlet 913 of the water outlet 900 is not lower than the highest level of the pure water tank 210. The level of the liquid level is set to such a height that when the normal temperature liquid flows into the vapor-liquid separation tube 912 through the initial inlet pipe 911, the air in the vapor-liquid separation pipe 912 can interrupt the water flow, thereby achieving the function of preventing siphoning.

Specifically, referring to FIG. 24 and FIG. 25, the manifold is configured to reduce the diameter in the direction of the water discharge, so that the manifold 930 can concentrate the liquid flowing from the tube of the top tube, which is advantageous for reducing the impact of the water flow and finally making the liquid The bottom end outlet 931 of the manifold 930 flows out smoothly and smoothly.

Preferably, the manifold 930 is a multi-stage step tube. Referring to FIG. 24 to FIG. 26, an overflow gap X is formed between the top end of the upper and lower spaced-apart manifold 930 and the bottom end of the top tube, and the outer circumference of the radially spaced confluence tube 930 is formed. A circumferential overflow passage Y is formed between the wall and the inner peripheral wall of the bottom pipe 920. Specifically, when the flow rate of the liquid flowing into the water discharge nozzle 900 is large, there is a case where the liquid does not flow out from the bottom end outlet 931 of the manifold 930, and therefore, the accumulation gap X and the circumferential overflow passage Y are provided to cause accumulation. The liquid in the cap tube lumen and the confluent lumen can overflow through the overflow gap X and flow into the circumferential overflow passage Y, thereby flowing out of the water outlet 921 of the nozzle 900.

Specifically, the bottom of the bottom tube 920 is formed in a frustum shape which is tapered from top to bottom, and the bottom inner peripheral wall of the bottom tube 920 is provided with a plurality of vertical drainage ribs 922 arranged at intervals in the circumferential direction, with reference to FIGS. 23 to 25. In this way, the liquid between the outer peripheral wall of the manifold 930 and the inner peripheral wall of the bottom tube 920 is condensed along the vertical drainage rib 922 to the water outlet 921 at the bottom end of the bottom tube, and then flows down from the water outlet 921 to the user. In the liquid cup. Further, in order to disperse the water vapor overflowing from the bottom end outlet 931 of the manifold 930, the bottom peripheral wall of the bottom tube 920 is preferably provided with a hollow exhaust port 923.

Preferably, as shown in FIG. 1 to FIG. 13 , a water treatment module 200 for preparing pure water, a soda module 3 for making soda water, and a gas supply system for soda are provided in the machine cavity of the net drink machine. The air supply device of 3 and the refrigeration device for cooling the soda module 3, the invention makes reasonable arrangement and linkage control of the above modules and devices, so that the net drink machine has the functions of pure water and soda water at the same time, satisfying A variety of drinking requirements for users.

In some embodiments described below, the refrigerating module 2 for refrigerating water and the heating module 500 for hot water can be provided in the machine cavity of the net drinker, so that the net drink machine can be under different drinking requirements of the user. Drinking water at different temperatures. That is, the net drink machine of the present invention can integrate one or more of various functional modules such as filtration, refrigeration, heating and soda, which greatly improves the user experience.

The basic structure and working principle of the soda module 3 will be explained below:

The soda module 3 includes a carbonization tank 31 for storing soda water, and the carbonization tank 31 is provided with a carbonization tank inlet nozzle 35 for supplying pure water, a carbonization tank outlet pipe 36 for discharging soda water, and a gas supply device. The air supply pipe 32, a pressure relief valve 33 for maintaining the air pressure in the carbonization tank 31, and a carbonization tank water discharge pipe 37 for draining in a specific case. Further, the carbonization tank 31 is provided with a carbonization tank temperature probe 38 for detecting the water temperature in the tank in real time, and a carbonization tank water level probe 39 for detecting the water level in the tank in real time. Preferably, the refrigerating apparatus includes a compressor 51, a condenser 52, and a coil evaporator 53 which are sequentially disposed in a refrigerant circuit. Of course, the refrigeration device may be a compressor refrigeration device or another refrigeration device such as a semiconductor refrigeration device, and will not be described here.

It should be noted that the water temperature in the tank below the tank of the carbonization tank 31 is lower than the water temperature above (ie, the soda water in the tank is based on the temperature differential layer), and the carbonization tank outlet pipe 36 extends below the tank to ensure The effluent has sufficient water pressure and ensures that the lower temperature soda is output preferentially. Therefore, the present invention preferably mounts the carbonization tank water inlet nozzle 35 in the water inlet of the carbonization tank 31 instead of the carbonization tank water inlet pipe. This is because the water flowing into the carbonization tank 31 from the carbonization tank water inlet nozzle 35 is sprayed, and does not disturb the temperature differential layer state maintained by the water in the tank, thereby ensuring that the user can optimally use the soda water at the drinking water temperature. Alternatively, a carbonization tank inlet pipe may be used, but it is preferable to provide a slow flow plate 34 for receiving and slow-flowing water in the carbonization tank 31, that is, pure water flowing from the carbonization tank inlet pipe first drops on the slow flow. The plate 34 is again slowly flowed into the water of the carbonization tank 31 through the edge of the slow flow plate 34.

The soda module 3 of the present invention will immediately enter the working state following the start of the net drinker. The working principle is as follows: on the one hand, the pure water is sprayed into the carbonization tank 31 through the carbonization tank inlet nozzle 35, and the sprayed water droplets will first fall on the slow flow plate 34 and then pass the edge of the slow flow plate 34. It flows into the original storage water of the carbonization tank 31 in a dispersed and slow manner. On the other hand, the air supply means (which may be the built-in gas cylinder 61 or the external gas cylinder 62) continuously communicates with the gas supply pipe 32 to supply carbon dioxide into the carbonization tank 31, and the soda module 3 can be discharged into the carbonization tank 31 through the pressure relief valve 33. Supersaturated air pressure ensures stable air pressure in the tank. At the same time, the refrigerating device cools the carbonization tank 31 to keep the water temperature in the tank within an appropriate range to ensure the dissolution rate of carbon dioxide in water (generally, the soda water is best at about 4 ° C). When the user needs to drink, the soda in the tank can flow through the carbonization tank outlet pipe 36 to the soda water outlet. In addition, during the operation of the soda module 3, the water temperature and water level can be controlled by the carbonization tank temperature probe 38 and the carbonization tank water level probe 39 to ensure stable and reliable operation of the entire soda module.

In addition, during the period when the user uses the net drinker, it is inevitable that some functional modules will not be used for a long time. For example, when the user does not use the soda module 3 for a long time, the soda water stored in the carbonization tank 31 gradually breeds bacteria and becomes spoiled water. Obviously, drinking degraded water greatly impairs the user's health. Here, the net drinker of the present invention is provided with a normally closed soda water high pressure valve in the carbonization tank outlet pipe 36. When the user wants to actively empty the degraded water in the carbonization tank 31, the high-pressure valve of the soda water channel can be triggered to clear the deteriorating water through the touch button on the control panel of the net drinker. Alternatively, a corresponding program may be set in the controller of the refreshing machine to periodically empty the deteriorated water in the carbonization tank 31. For example, the soda water high pressure valve can be set to control the valve to open when the trigger interval reaches the preset emptying time, that is, when the system detects the soda water high pressure valve for a certain period of time (ie, the above preset emptying time, according to the actual situation) The controller will automatically control the soda water high pressure valve to open. It should be noted that the above-mentioned soda water high pressure valve and the soda water outlet are connected with a carbonized tank drain pipe 37. During the process of deteriorating water in the carbonization tank 31, the soda water high pressure valve is opened, and the soda water outlet is closed. The degraded water can be discharged from the outside of the machine from the carbonization tank drain pipe 37. Further, a carbonization tank drain pipe 37 may be provided on the carbonization tank 31, and a carbonization tank drain switch valve may be provided on the carbonization tank drain pipe 37.

Preferably, the net drinker further includes a refrigeration module 2, and the cold tank 21 in the refrigeration module 2 is used to supply water to the carbonization tank 31. Specifically, the pure water in the pure water tank 210 of the water treatment module 200 can flow into the cold tank 21 through the cold tank inlet pipe 23 under the action of the water supply pump, and the cold tank outlet pipe 24 in the cold tank 21 communicates with the carbonization tank The carbonization tank inlet nozzle 35 of 31 forms a double tank communication water pipe. Further, the two-tank communication water pipe can branch out of the cold water outlet pipe 24 connected to the cold water outlet. The user can open the cold water spout to take cold water, open the soda water spout to take the soda, or integrate the cold water spout and the soda spout into the same spout to simplify the spout structure. Further, the cold tank 21 is provided with a cold tank temperature probe 22 for sensing the temperature inside the tank in real time and a cold tank water level probe for sensing the water level of the cold tank in real time.

The soda module 3 of the net drinker of the present invention may also have different structures and cooling modes, which will be described below by four different embodiments. However, it should be noted that the four embodiments are only for explaining the present invention, and should not be construed as limiting the invention, that is, other structures or control methods of the soda module 3 applied to the net drinker should also belong to Within the scope of the present invention.

Embodiment 1 (water treatment module 200 provides normal temperature water to the soda module 3)

As shown in FIG. 1 to FIG. 3, the present embodiment provides a netting machine. The soda module 3 in the netting machine can be directly supplied with water through the water treatment module 200, and belongs to the self-cooling type soda module 3. It should be noted that since the pure water filtered from the water treatment module 200 is normal temperature water (about 25 ° C), the temperature difference between the water temperature and the water temperature (about 4 ° C) when the soda taste is optimal is large, so the refrigeration device It takes a lot of time to cool the room temperature water. On the other hand, the net drinker in the present embodiment can reduce the production cost and has a wide audience range by omitting the device for pre-cooling the normal temperature water. Among them, the coil type evaporator 53 is wound as a cooling line on the outer casing of the carbonization tank 31 of the soda module 3 to cool the soda water in the tank.

Embodiment 2 (cooling module 2 and system soda module 3 are both cooled)

As shown in FIGS. 1 and 2 and FIGS. 4 to 9, the present embodiment provides a net drinker including a refrigeration module 2 and a soda module 3. During the operation of the netting machine, the water treatment module 200 supplies normal temperature water to the cold tank 21 in the refrigeration module 2, the cold tank 21 supplies cold water to the carbonization tank 31, and the air supply unit supplies air to the carbonization tank 31, and the refrigeration unit The cold tank 21 and the carbonization tank 31 can be cooled synchronously, or can be cooled independently of each other.

The different cooling modes of the soda module 3 in the present embodiment will be separately described below.

1, 2, 8, and 4 to 6 show the case where the cold tank 21 and the carbonization tank 31 are independently cooled.

At this time, the refrigeration apparatus includes a compressor 51, a condenser 52, and a first coil evaporator 531 and a second coil evaporator 532 which are disposed in parallel in the refrigerant circuit. Among them, the first coil type evaporator 531 provided with the first refrigerant solenoid valve 54 is wound around the cold tank 21 as the first cooling line, and the second coil type evaporator 532 provided with the second refrigerant solenoid valve 55 is used as the first The second cooling line is coiled around the carbonization tank 31, and the temperature of the liquid in the cold tank 21 and the carbonization tank 31 is controlled by the corresponding first refrigerant solenoid valve 54 and second refrigerant solenoid valve 55.

As described above, the refrigeration apparatus according to the present embodiment can independently cool the cold tank 21 and the carbonization tank 31, and the compressor 51 can always be in an operating state, and the control method thereof is relatively simple, and the carbonization tank 31 can be prevented from being excessively cooled. In case of high reliability.

1, 2, 4, 5, and 7 and 9 show the case where the cold tank 21 and the carbonization tank 31 are simultaneously cooled.

At this time, the refrigerating apparatus includes a compressor 51, a condenser 52, and a coil type evaporator 53 which are sequentially disposed in the refrigerant circuit, and the coil type evaporator 53 is sequentially wound in series as a synchronous cooling line to the cold tank 21 and the carbonization tank 31. .

When the in-tank temperature of the cold tank 21 sensed by the cold tank temperature sensing probe 22 is greater than the upper temperature threshold of the cold tank, the controller of the net drinker controls the compressor 51 to be activated to pass the refrigerant through the coil evaporator 53. Further, when the in-tank temperature of the cold tank 21 sensed by the cold tank temperature sensing probe 22 is lower than the threshold value at the cold tank temperature, the controller controls the compressor 51 to be turned off to cut off the refrigerant flow.

For the carbonization tank 31, when the in-tank temperature of the carbonization tank 31 sensed by the carbonization tank temperature sensing probe 38 is greater than the upper limit of the carbonization tank temperature, the controller controls the compressor 51 to be activated to pass the refrigerant through the coil evaporator 53. . Further, when the in-tank temperature of the carbonization tank 31 sensed by the carbonization tank temperature sensing probe 38 is less than the threshold value at the carbonization tank temperature, the controller controls the compressor 51 to be turned off to cut off the refrigerant circulation.

It can be seen that when the cold tank 21 and the carbonization tank 31 are synchronously cooled, the refrigeration module 2 and the soda module 3 are respectively provided with two corresponding control programs related to the start and stop of the compressor 51. However, the two control programs are not completely independent of each other, because the water temperature required for the soda water is lower than the water temperature required for the cold water. When the compressor 51 is started and the cooling of the cold tank 21 and the carbonization tank 31 is started synchronously, The water temperature in both tanks continued to drop. However, it is obvious that the cold tank temperature probe 22 will feed back the signal for controlling the closing of the compressor 51 to the controller prior to the carbonization tank temperature probe 38, which causes the soda water in the carbonization tank 31 to not reach the desired level. The water temperature stops cooling. If the user only drinks cold water for a period of time without drinking soda water, the controller will re-drive the compressor 51 to synchronously cool the cold tank 21 and the carbonization tank 31 whenever the fresh water tank 21 is filled with new normal temperature water. Since the non-drinking low-temperature soda water is always stored in the carbonization tank 31, the temperature becomes lower and lower after multiple cooling. When the water temperature is lower than -1 ° C to 0 ° C, the soda water freezes, causing the carbonization can 31 to burst.

Based on the problem that the water temperature may be too cold in the above-described carbonization tank 31, when the cooling tank 21 and the carbonization tank 31 are simultaneously cooled, it is necessary to set a corresponding subcooling protection program in the controller. In terms of construction, it is necessary to provide a supercooled drain pipe and a supercooled drain valve for opening and closing the subcooled drain pipe in the carbonization tank 31.

Further, the controller may be configured to control to open the subcooled drain valve to pass the supercooled soda water through subcooling when the in-tank temperature of the carbonization tank 31 is less than a threshold value of the carbonization tank temperature (preferably -1 ° C to 0 ° C) The drain pipe is discharged outside the machine. And, when the temperature inside the can of the carbonization tank 31 is not less than the threshold value at the temperature of the carbonization tank, the control recloses the subcooling drain valve.

After draining the cold soda water, the carbonization tank 31 will be in a water shortage state. At this time, the controller may be further configured to control to start the water supply pump when the carbonization tank water level sensed by the carbonization tank water level probe 39 is less than the threshold value of the carbonization tank water level, thereby causing the water treatment module 200 to replenish water to the cold tank 21 and the cold tank 21 The water is replenished to the carbonization tank 31 accordingly, and when the carbonization tank water level sensed by the carbonization tank water level probe 39 is greater than the upper limit of the carbonization tank water level, the controller controls to shut down the water supply pump. Under this water level control program, the water level in the carbonization tank 31 will gradually return to normal.

In the above-described hydration process for the carbonization tank 31, since the temperature of the water in the carbonization tank 31 rises again, the controller again controls the compressor 51 to restart to cool it.

Further, the subcooled drain pipe with low temperature soda water can be coiled as a cooling pipe on the outer casing of the heat generating device in the net drinker, that is, the supercooled drain pipe can function as a heat sink in a specific case. For example, the subcooled drain can be coiled as a cooling water pipe to the condenser 52 connected to the compressor 51, so that the heat of the condenser 52 can be quickly taken away to achieve better protection of the condenser 52. Moreover, the supercooled drain pipe may also preferably flow into the filtered waste water pipe to discharge the supercooled soda water and the waste water together, which arrangement can simplify the piping structure of the net drinker, thereby saving the space inside the machine.

Embodiment 3 (cooling module 2 is cooled and soda module 3 is insulated)

As shown in FIG. 10, the present embodiment provides a net drink machine including a soda module 3 disposed in a machine cavity, a refrigeration module 2, a water treatment module 200 for supplying water to the refrigeration module 2, and a refrigerating device. And a gas supply device for supplying gas to the soda module 3. Wherein, the refrigerating device is used for refrigerating the cold tank 21 of the refrigerating module 2, the cold tank 21 supplies cold water to the carbonization tank 31 of the soda module 3, and the outer tank of the carbonization tank 31 is provided with a heat insulating layer to maintain the soda in the tank The low temperature state of the water.

Preferably, the net drinker further includes a controller configured to control opening of the carbonization tank outlet pipe 36 when the in-tank temperature of the carbonization tank 31 sensed by the carbonization tank temperature sensing probe 38 is greater than the upper limit of the carbonization tank temperature. The normally closed soda water high pressure valve causes the carbonization tank 31 to discharge the warmed soda water that has been stored for a long period of time. When the soda water in the carbonization tank 31 is emptied, the soda water high pressure valve is returned to the closed state.

At this time, the carbonization tank water level probe 39 senses that the carbonization tank 31 is in a water shortage state, that is, when the carbonization tank water level is lower than the threshold value of the carbonization tank water level, the controller immediately controls the startup of the water supply pump to promote the water treatment module 200 to the cold tank 21 In the hydration, the cold tank 21 also hydrates the carbonization tank 31. When the carbonization tank water level sensed by the carbonization tank water level probe 39 is greater than the water level upper threshold, the controller controls to close the water supply pump to stop the water supply.

In addition, when the cold tank water level sensed by the cold tank water level probe is less than the threshold value of the cold tank water level, the water supply pump is controlled to start to promote the water treatment module 200 to replenish water, and when the cold tank water level probe senses the cold tank water level is greater than the cold tank water level. At the threshold, control shuts off the water supply pump to stop hydration.

Specifically, the cold tank 21 is provided with a cold tank drain pipe 25, and a cold tank drain switch valve is provided in the cold tank drain pipe 25, so that when the net drinker needs to drain the deteriorated water in the cold tank 21, it can be controlled. The cold tank drain switch valve is opened to cause the deteriorated water in the cold tank 21 to be discharged outside the machine through the cold tank drain pipe 25. When the degraded water is completely emptied, the cold tank venting switch valve is closed again, at which time the pure water tank 210 replenishes the cold tank 21.

Preferably, the cold tank drain pipe 25 and the carbonization tank drain pipe 37 are connected to the bottoms of the cold tank 21 and the carbonization tank 31, respectively, and at this time, the deteriorated water in the cold tank 21 and the carbonization tank 31 can naturally flow under the action of water pressure. In the cold tank drain pipe 25 and the carbonization tank drain pipe 37, and only by opening the cold tank drain switch valve and the carbonization tank drain switch valve, the spoiled water can be discharged out of the machine without the need of an additional pumping device, which simplifies the whole The cleaning and emptying structure of the machine. In addition, the controller can control the start and stop of the cold tank drain switch valve, the carbonization tank drain switch valve, and the drain solenoid valve 522, and when any of the valves are not turned on within a preset time interval, the controller is configured to Controlling the opening of the valve to drain the liquid, generally, the preset time interval is not less than 5 days.

The water treatment module 200 shown in Figs. 11 to 13 can be preferably used in the net drinker of the present invention. The water treatment module 200 includes a horizontally disposed filter element and a fixedly disposed filter cartridge mount 20. The filter cartridge is inserted laterally and inwardly from the front side of the casing 100 of the net drinker into the filter cartridge mount 20, and is capable of being pulled laterally outward. The filter cartridge 20 is integrally replaced, that is, the filter element is placed parallel to the horizontal embedding direction of the net drinker. In this way, when the filter element needs to be replaced, the user only needs to withdraw the filter element laterally outward from the filter cartridge mount 20 from the front side of the casing 100, and then replace the filter element from the front side of the casing 100 laterally inward. It can be inserted into the filter cartridge mount 20. The replacement of the filter element does not require the whole machine of the net drink machine (especially the embedded net drink machine) to be taken out from the cabinet or the wall, and the filter element mount 20 and the filter element are not required to be withdrawn from the machine cavity. The filter element can be replaced as a whole, and the operation is simple and convenient, which can greatly reduce the cumbersomeness of the filter element replacement, and is beneficial to improving the user experience. In addition, the filter cartridge mount 20 is not taken out from the machine cavity together with the filter element, that is, the filter cartridge mount 20 is fixedly disposed in the machine cavity, thereby, when the user replaces the filter cartridge by himself, the filter cartridge can be effectively prevented from being installed due to the user's misoperation. The components such as the pipelines provided on the seat 20 interfere with each other (such as bumping the pipeline), which is beneficial to improve the reliability and service life of the whole machine.

Specifically, the water treatment module 200 further includes a filter core having a reverse osmosis filter layer, a water filter booster pump 90 disposed upstream of the water inlet of the reverse osmosis filter layer, and a filtered filter waste pipe, which are mentioned in the above embodiment. The supercooled drain pipe, the cold tank drain pipe 25, the carbonized tank drain pipe 37, and the hot tank drain pipe 521 can be connected to the filtered waste pipe, so that the confluence to the waste water is discharged out of the machine, simplifying the pipeline structure. Among them, the reverse osmosis filter layer is a filter layer mainly composed of an RO membrane, and can effectively remove impurities such as heavy metal ions or bacteria.

Preferably, referring to FIG. 27 to FIG. 29, a condenser vent 110' is disposed on the back panel of the casing 100, and the condenser heat dissipating assembly 500' is disposed on the back panel and disposed on the condenser vent 110'. The condenser 52 is disposed adjacent to the condenser vent 110', wherein when the condenser heat dissipating assembly 500' is in operation, the air around the condenser 52 can be driven to flow toward the condenser vent 110', and then through the condenser vent 110' The water flows out from the back panel. Thus, a large amount of heat accumulated in the air surrounding the condenser 52 can be removed as the air flows toward the condenser heat dissipation port 110', thereby achieving the purpose of air-cooling and cooling the condenser 52. It is beneficial to ensure the normal operation of the condenser 52, thereby improving the service life of the condenser 52 and even the whole machine, which can greatly improve the user experience. In addition, the condenser vent 110' is disposed on the back panel of the casing 100, and the extracted hot air can be prevented from directly flowing to the environment where the user is located, and the heat dissipation efficiency can be further improved, thereby greatly improving the user experience. .

Specifically, the condenser heat dissipation assembly 500' includes a fan 510' and a cylindrical air duct 520' accommodating the fan 510'. Referring to FIGS. 27 to 29, the rear end opening of the air passage 520' and the condenser heat dissipation port 110' Connected. Further, the front end of the air duct 520' is connected to the condenser 52, that is, the condenser heat dissipating component 500' and the condenser 52 are sequentially stacked on the condenser heat dissipating port 110' of the back panel, so that it is more favorable to the periphery of the condenser 52. The air flows quickly and smoothly to the condenser vent 110', thereby greatly increasing the air-cooling heat dissipation effect of the condenser heat sink assembly 500' for the condenser 52. Of course, the condenser heat dissipating component 500' can also be in various other suitable manners, and details are not described herein again.

Preferably, in order to ensure that the heat dissipated during operation of the condenser 52 can be discharged into the casing 100 in a timely and rapid manner, the condenser heat dissipating assembly 500' is set to operate in synchronization with the condenser 52, that is, when the condenser 52 is started, the condenser The heat sink assembly 500' operates to forcibly convect heat the condenser 52, and when the condenser 52 stops operating, the fan 510' also stops rotating accordingly.

Preferably, referring to FIG. 1 and FIG. 2, the side panel of the casing 100 is provided with a side air inlet 120, and/or the bottom of the front panel of the casing 100 is provided with a forward air outlet, and/or the back of the casing 100. There is a rear air inlet on the panel. Specifically, the above-mentioned advancing tuyere, side air inlet 120 and rear air inlet can be arranged in different combinations on the casing 100 of the embedded net drink machine of the present invention, and the specific position and number of each air inlet are determined according to actual heat dissipation requirements. Accordingly, various combinations of the advance tuyere, the side air inlet 120, and the rear air inlet are also contemplated by the present invention.

Preferably, the condenser heat sink assembly 500' includes a condenser temperature probe that is attached to the condenser 52 so that the condenser 52 real-time temperature can be detected more sensitively. Further, the operating speed of the fan 510' is positively correlated with the temperature of the condenser 52 detected by the condenser temperature sensing probe. Thus, the operating speed of the fan 510' is accelerated as the temperature of the condenser 52 rises, and vice versa. The rotation speed also slows down as the temperature of the condenser 52 decreases, which facilitates the accurate heat dissipation of the condenser 52, thereby greatly reducing the energy consumption of the condenser heat dissipating component 500' or even the whole machine. Among them, the condenser temperature sensor can be a thermocouple temperature sensor or a other type of temperature sensor such as a thermistor temperature sensor, which will not be mentioned here.

As shown in FIG. 17, FIG. 21 and FIG. 22, the netting machine comprises an ice making module having an evaporator ice making assembly, the evaporator ice making assembly comprising an ice making evaporator 1' and a nozzle water circuit board 2', making ice. The evaporator 1' protrudes downward from the condensation column 11, and the nozzle water plate 2' is provided with a nozzle port, and the spray water of the nozzle port can flow along the condensation column 11 and condense on the outer surface of the condensation column 11 to surround the condensation column 11 Icicle 14'.

In the ice making assembly, the ice tray is not used, but the direct spraying method for the ice making evaporator 1' is adopted, and the drainage column 11 protruding from the ice making evaporator 1' serves as a drainage function. In the ice making process, as shown in Fig. 22, the water on the condensation column 11 has fluidity and freezes while flowing, thereby ensuring the transparency of the ice cube, high hardness, and having the advantages of roundness and controllability. Among them, the condensation column 11 is preferably in the shape of a short and thick bullet, so that the formed icicles 14' are large and thick, which meets the needs of use.

In the embodiment shown in Fig. 21, the nozzle waterway plate 2' is preferably a flat plate provided with a plurality of through holes 21' spaced apart, and the ice making evaporator 1' includes evaporation disposed on the top surface of the nozzle waterway plate 2'. The body 12' has a plurality of condensation columns 11 extending from the evaporator body 12' and penetrating downwardly through the through holes 21' in a one-to-one correspondence. That is, the ice making evaporator 1' and the nozzle water circuit board 2' are matched components, forming a simple fitting and fitting manner.

More specifically, the evaporator body 12' is preferably a U-shaped cooling drain tube as illustrated, and the plurality of condensation columns 11 are arranged along the extending direction of the pipe of the U-shaped cooling discharge pipe, and the nozzle opening may be disposed toward the U-shaped cooling pipe And / or condensation column 11 spray. Wherein, when the nozzle opening is provided on the top surface of the flat plate, the spray water can flow downward through the through hole 21' along the surface of the condensation column 11 to condense into the icicle 14'. When the nozzle opening is provided on the bottom surface of the flat plate, it can be directly sprayed on the surface of the condensation column 11 to form an icicle 14'. Among them, according to the amount of flowing refrigerant in the evaporator and its cooling effect, one part of the spray water condenses and freezes, and a part of it is cooled to form a cooling water drop.

After the spray water is condensed into the icicle 14', in order to facilitate the deicing, a mechanical deicing method such as vibration or tapping and a deicing mechanism may be employed, but the heating deicing method in the embodiment shown in FIG. 18 may also be employed. That is, the evaporator ice making assembly further includes a deicing heating element 3' for heating the condensation column 11. The deicing heating element 3' may be a heating wire, a heat generating tube or a thick film, etc., and may be arranged to contact the evaporator as shown in the drawing to heat the evaporator. It can also be disposed in the inner cavity of the condensation column 11. When the inner portion of the condensation column 11 is filled with the refrigerant, the deicing heating element 3' may also be wrapped in the interlayer provided on the outer peripheral wall surface of the condensation column 11 and/or the outer peripheral wall.

In order to control the amount of ice and the need to protect structural devices, the timing of deicing is critical. Alternatively, the ice making evaporator 1' may be placed to be pressurized on the nozzle waterway plate 2', and the nozzle waterway plate 2' is provided with a weighing and measuring element for detecting the weight change of the ice making evaporator 1'. When the weighing metering value of the weighing metering element is greater than the set weighing threshold, the heating is performed to defrost the condensation column 11 and is closed when the weighing metering value is less than the set weighing threshold. In this way, automatic control of deicing can be achieved, and the amount of ice making can be calculated.

19 and 20 completely illustrate the above-described ice making evaporator 1' with a condensation column 11, which comprises a stainless steel cooling pipe, and a refrigerant is passed through the condensation pipe so as to contact the surface of the condensation pipe. The water forms contact cooling, and the cooling pipe is further provided with a plurality of condensation columns 11 arranged at intervals in the pipeline direction. The condensation column 11 extends vertically downward, and the water on the outer surface of the condensation column 11 can be condensed into a surrounding condensation column. The icicle 14' of 11 is as shown in Figs. 21 and 22 .

The condensing tube is bent to form an evaporator body 12' and a condensation column 11, which is connected to the refrigeration system circuit through a refrigeration line 13'. It is well known that the evaporator is one of the four major components of the refrigeration system, and the connection relationship between the evaporator and the refrigeration circuit is common knowledge and will not be described in detail herein.

It should be noted that the existing cooling pipe is mostly made of copper material to obtain better heat conduction and cooling effect. At the same time, in order to improve the gloss and anti-corrosion performance of the copper tube, it is necessary to carry out nickel plating on the surface of the copper tube. On the one hand, the nickel plating technology is not environmentally friendly, on the other hand, in the process of use, nickel ions are easily precipitated, thereby polluting drinking water. Once dissolved in water, nickel will exceed the standard, which will cause direct harm to the human body. Therefore, a stainless steel evaporator structure is preferably employed in the present embodiment. The evaporator structure shown in Figures 19 through 22 is identical to a conventional copper evaporator, but is replaced by a stainless steel material, particularly a food grade stainless steel 304 material. The thermal conductivity of stainless steel material is slightly worse than that of copper material, but it can basically meet the demand of ice making, and it has high safety. It can eliminate the copper plating process, improve production efficiency, reduce related production cost, and improve the hygiene of the evaporator. safety.

As shown in Fig. 17 and Fig. 18, the ice making module is built in the net drinker. The ice making module comprises an ice can 10', the evaporator ice making assembly described above being built into the tank cavity of the ice can 10' and preferably located at the top of the tank cavity, the tank cavity being partitioned into the bottom water storage chamber 20' and the upper portion The ice storage chamber 30' is provided with an ice guiding guide 4 directly under the evaporator ice making assembly, and the ice guiding member 4 receives the ice cubes and ice water falling from the evaporator ice making assembly and guides them to the ice storage chamber respectively. 30' and water storage chamber 20'.

Thus, the ice making module can simultaneously complete ice making and cooling water through the same evaporator in one ice tank 10'. Here, when the icicle 14' is dropped, in order to receive the ice and transport it to the ice storage chamber 30', it is necessary to provide the ice guide 4 in particular. As shown in FIG. 18, as an example, the ice guiding guide 4 is an inclined sliding plate that protrudes obliquely downward from the inner wall of the ice can 10' toward the top of the ice storage chamber 30', and the icicle 14' falls to After the skateboard, it will slip into the ice storage chamber 30'. By adjusting the height of the ice guiding guide 4, the crushing effect on the icicles can be selectively adjusted. At the same time, the inclined slide plate may be provided with a water hole (not shown) and/or an inclined flow gap is formed between the inclined slide plate and the top edge of the ice storage chamber 30', so that the ice water flowing from the evaporator ice making assembly can be The water storage chamber 20' flows downward through the water hole or the overflow gap.

An automatic ice discharging device is usually provided in the ice storage chamber 30'. The automatic ice discharging device can adopt various suitable structures and manners such as a conveyor belt or a ribbon. In the preferred embodiment illustrated, the automatic ice-discharging device is preferably transported by means of a spiral belt, i.e. a guide icicle 5 with a helical guide vane 5, which is driven by the icicle drive motor 6, a spiral The guide vanes move the ice block at the bottom of the ice storage chamber 30' upward, and the top side wall of the ice tank 10' is provided with an ice outlet 101', and the ice guide 5 is obliquely disposed at the bottom of the ice storage chamber 30' and the ice outlet 101. The ice cube at the bottom of the ice storage chamber 30' can be transported to the ice outlet 101' between and under the driving of the icicle driving motor 6. By appropriately opening the ice exit door assembly 102' at the ice exit 101', an appropriate amount of ice can be outputted externally.

When applied to the embedded ice maker, since the installation position of the ice outlet 101' or the like is relatively high, the horizontal inclination angle of the guide icicles 5 transported by the spiral belt can be set larger, thereby increasing the height of the ice outlet to meet the requirements. The technical requirements for high-level ice-out of embedded ice machines (such as embedded net drinkers).

In the present embodiment, the ice making module is applied to the embedded net drinking machine. At this time, due to the installation characteristics of the embedded net drinking machine, the height of the water outlet and the ice outlet is required to be high, and other conventional ice discharging devices are difficult to meet the requirements. . In the illustrated embodiment, the horizontal slant angle of the icicles 5 can be set to 50° or more, thereby increasing the height of the vents by at least 100 mm when the icicle slope is greatly increased to meet design requirements.

In addition, the ice making module of the present embodiment is further provided with a full ice sensing system. For example, an ice outlet temperature sensor 103' near the ice outlet 101' is provided at the top of the ice can 10'. At this time, the controller of the ice making module can be configured to be inductive temperature at the ice outlet temperature sensor 103'. When the temperature is not higher than the surface temperature of the ice (for example, below zero), a full ice signal is issued and the evaporator ice making unit is controlled to stop the ice making operation to prevent excessive ice making and save energy. That is, when the height of the ice accumulated in the ice storage chamber 30' reaches the installation height of the ice outlet temperature sensor 103', the ice outlet temperature sensor 103' contacts the ice cube and feeds back the full ice signal.

Further, however, an ice curtain 104' and an ice curtain sensor 105' may be disposed on the ice entering side. As shown in FIG. 18, the ice curtain 104' is an overhanging swinging member pivotally swinging around the top end of the ice curtain 104', and the bottom end of the ice curtain 104' is suspended to the end position of the ice receiving guide 4, and the ice curtain sensor 105 'Used to detect that the ice curtain 104' is in a dangling state or a yaw state. When ice cubes slide from the ice guiding guide 4 to the ice storage chamber 30', the ice cubes strike the ice curtain 104', causing the ice curtain 104' to produce a pendulum yaw, or when the ice cube of the ice storage chamber 30' is When the left side of the figure is full, the ice curtain 104' can be topped to the yaw state. The ice curtain 104' remains in a dangling state only when there is no ice impact or ice is ejected.

Accordingly, the ice curtain sensor 105' can be configured to generate an ice side full ice signal when the ice screen 104' is detected to remain in the yaw state. For example, a magnet may be disposed at the bottom end of the ice curtain 104', and the ice curtain sensor 105' is used to sense the magnetic field strength, so that the ice screen 104' is suspended by a parameter setting such as a magnetic field strength threshold and a magnetic field strength duration. State or yaw state.

In summary, more preferably, when the ice curtain sensor 105' is configured to detect that the ice curtain 104' is maintained in the yaw state and generate an ice side full ice signal, the ice exit temperature sensor 103' is configured to sense the temperature is not high. When the ice surface temperature is generated and the ice side full ice signal is generated, the controller may be configured to: when receiving the ice on the ice side, drive the ice guide 5 to generate an ice stirring action to The ice cube on the ice inlet side is balanced to the ice exit side, and when the ice inlet side full ice signal and the ice exit side full ice signal are synchronously or successively received, it is determined that the ice storage chamber 30 ′ is at The ice is full and controls the evaporator ice making assembly to stop the ice making operation.

Here, since the nozzle water passage 2' is disposed at the top, the ice making module further includes a circulating water pump 7 for pumping the water storage chamber 20' to the nozzle water passage 2'. The ice water is sprayed to the evaporator to help condense into ice quickly. The water storage chamber 20' may be provided with various types of sensors 8, such as a water level sensor and a temperature sensor, to monitor the ice water level and the water temperature in real time, thereby making corresponding adjustment control.

In addition, the ice making module further comprises an ice making carbonization tank 9, the top side wall of the ice tank 10' is provided with an ice water outlet (not shown), and the ice water in the water storage chamber 20' can be supplied separately by the ice water pump 40. Ice carbonization tank 9 and ice water outlet. Therefore, the ice making module is further integrated with a soda water module, and the ice making carbonization tank 9 receives the ice water of the water storage chamber 20' and a certain pressure of the air supply device (which may be a built-in gas cylinder 61 or an external gas cylinder 62). Carbon dioxide gas, which can output soda water. In this way, through the built-in integrated ice-making carbonization tank 9, the ice-making module can integrate three functions of cooling water, ice making and soda water. Therefore, in the ice making module of the present invention, ice making, refrigerating water, and soda water share a water tank, and an evaporator simultaneously makes ice and refrigerating water. The internal structure of the ice making module is compact, highly integrated, and has a reasonable layout, which can realize various functions and save limited installation space in the machine.

Specifically, in Fig. 18, the refrigeration system to which the ice making evaporator 1' is connected includes an ice making compressor 50 of an external peripheral, an ice making condenser, an accumulator, and the like. In addition, the pure water filtered by the water treatment module 200 is introduced into the ice making module and the heating module 500; the ice making carbonization tank 9 can be built in or externally placed in the ice making module, and the gas supply module is connected to the ice making carbonization through the air guiding tube.
