In order to solve the technical problems that the heat dissipation of a condenser 40 of ice making equipment in the prior art affects the ice making efficiency and increases the ice making energy consumption, the application provides the ice making equipment and the ice making method, which can improve the heat dissipation of the condenser 40 and improve the ice making efficiency; while also reducing the temperature rise of the environment surrounding the condenser 40 and improving the user's physical examination.

An embodiment of the present application provides an ice making apparatus, which, as shown in fig. 1 to 4, mainly includes a compressor, an evaporator, a condenser 40, an ice making film 20, and a water tray 10. The compressor, the evaporator and the condenser 40 are connected to form a refrigeration loop for cooling medium circulation, the refrigerant is compressed by the compressor to become a high-temperature high-pressure gaseous refrigerant, the high-temperature high-pressure gaseous refrigerant enters the condenser 40 to be condensed and release heat to the environment, the condensed liquid refrigerant enters the evaporator to evaporate and absorb heat after being throttled, and the evaporated gaseous refrigerant enters the compressor again to be compressed. The ice making film 20 is generally made of metal and includes a mold with a grid structure, the ice making film 20 is attached to an evaporator, and the evaporator is used to cool the ice making film 20.

The water receiving tray 10 is arranged below the ice making film 20 and is connected with the water distribution assembly 30, the water distribution assembly 30 can distribute water stored in the water receiving tray 10 towards the ice making film 20, and the water receiving tray 10 can receive low-temperature water which flows down from the ice making film 20 and is not frozen. The water receiving tray 10 is also connected with a drainage pipeline 50, the drainage pipeline 50 extends to the condenser 40 and can discharge low-temperature water in the water receiving tray 10 to the condenser 40, and the condenser 40 is cooled by utilizing the heat exchange between the low-temperature water and the condenser 40.

When the ice making device is operated, the low-temperature water which flows down from the ice making film 20 and is not frozen is recovered by the water receiving disc 10, then the low-temperature water is discharged to the condenser 40 through the drainage pipeline 50, the condenser 40 is cooled by means of heat exchange between the low-temperature water and the condenser 40, the influence of insufficient heat dissipation of the condenser 40 on the ice making efficiency is avoided, meanwhile, the temperature rise around the condenser 40 is restrained, and the use experience of a user is improved; by discharging the low-temperature water, the water temperature of the water receiving disc 10 is conveniently controlled by supplementing water to the water receiving disc 10, the water distribution efficiency of the water distribution assembly 30 to the ice making ice film 20 is prevented from being influenced by ice residues generated in the water receiving disc 10, the water distribution energy consumption is reduced, and the ice making energy consumption is further reduced.

Referring to fig. 1, 2 and 4 in combination, a water pump may be provided at the water receiving tray 10 such that one end of the drain pipe 50 is connected to the water pump and the other end extends to the condenser 40. The drain line 50 may be curved to fit the condenser 40, and the low-temperature water exchanges heat with the condenser 40 via the drain line 50. The drain line 50 may also be used to spray low-temperature water directly onto the surface of the condenser 40, and to spray water to cool the condenser 40. To improve spray uniformity, the end of the drain line 50 extending to the condenser 40 may also be connected to a spray assembly.

The ice making device further comprises an ice making controller 70, wherein the ice making controller 70 is used for controlling the ice making device to automatically make ice according to user settings, in the embodiment of the application, the drainage pipeline 50 is provided with the drainage electromagnetic valve 75, the ice making controller 70 is connected with the drainage electromagnetic valve 75 and is used for controlling the automatic opening of the drainage electromagnetic valve 75 to drain water, and the condenser 40 is cooled while the water receiving tray 10 is prevented from generating ice residues, so that heat accumulation at the condenser 40 is avoided, and ice making efficiency is prevented from being influenced; while reducing the condenser 40 from causing a significant increase in ambient temperature, affecting the user experience. The ice making controller 70 automatically controls the setting of the drain solenoid valve 75 to open the drain, thereby improving the degree of automation of the ice making apparatus and simplifying the ice making operation. The control logic of the ice making controller 70 for controlling the opening and closing of the drain solenoid valve 75 is referred to as the following embodiments.

In some embodiments, the ice-making controller 70 may control the drain solenoid valve 75 to open the drain and cool down the condenser 40 according to the water storage temperature in the drip tray 10. A first temperature sensor 71 may be provided in the drip tray 10, and the first temperature sensor 71 is connected to the ice-making controller 70. The first temperature sensor 71 serves to detect the temperature of the inner water stored in the water receiving tray 10 and is capable of feeding back the detected water stored temperature to the ice-making controller 70. When the water storage temperature of the water receiving tray 10 is lower than the first preset value, the ice making controller 70 controls the water discharge solenoid valve 75 to be opened, so that low-temperature water in the water receiving tray 10 is discharged, and ice residues are prevented from being generated, and water distribution to the ice making film 20 and subsequent ice making efficiency are prevented from being influenced.

When the water receiving tray 10 is used for draining water, water needs to be distributed to the water receiving tray 10, so that the water quantity in the water receiving tray 10 is ensured, and further, the continuous ice making is ensured. By supplementing water to the water tray 10, the water storage temperature of the water tray 10 can be raised. When the water storage temperature of the water receiving tray 10 is higher than the second preset value, the ice making controller 70 controls the water discharging electromagnetic valve 75 to be closed, so that the influence on ice making efficiency when the water storage temperature in the water receiving tray 10 is too high and the water is sent to the ice making film 20 through the water distribution assembly 30 is avoided. The second preset value is larger than the first preset value, that is, by setting the first preset value and the second preset value, not only can the ice residues in the water receiving disc 10 be effectively prevented, but also the ice making speed of the ice making film 20 is obviously reduced due to the fact that the water storage temperature of the water receiving disc 10 is too high. Illustratively, the first preset value may be set to 2 ℃ and the second preset value may be set to 15 ℃.

In some embodiments, the ice making controller 70 may also control the opening and closing of the drain solenoid valve 75 according to the discharge temperature of the compressor discharge. When the discharge temperature of the compressor is too high, the heat radiation load of the condenser 40 increases significantly, and heat accumulation is likely to occur at the condenser 40. In this embodiment, a second temperature sensor 72 is provided at the exhaust port of the compressor, the second temperature sensor 72 is connected to the ice making controller 70, and the second temperature sensor 72 is used to detect the exhaust temperature of the compressor and can feed back the detected exhaust temperature to the ice making controller 70. When the discharge temperature of the compressor is higher than the third preset value, the ice making controller 70 controls the water discharge solenoid valve 75 to be opened, and the heat accumulation of the condenser 40 is avoided to influence the ice making efficiency by discharging water to the condenser 40 for cooling.

When the discharge temperature of the compressor is lower than the fourth preset value, the ice-making controller 70 controls the water discharge solenoid valve 75 to be closed, thereby reducing the loss of cold energy of the water stored in the water pan 10, so as to cool the condenser 40 when heat is accumulated at the condenser 40. The third preset value is greater than the fourth preset value, which may be set to 70 c and the fourth preset value may be set to 50c, in general.

In some embodiments, the ice making controller 70 may also control the opening and closing of the drain solenoid valve 75 according to the temperature of the condenser 40. When the temperature of the condenser 40 is too high, it means that the heat dissipation of the condenser 40 is insufficient to generate heat accumulation, which in turn results in insufficient cooling of the ice making film 20 by the evaporator, affecting the ice making efficiency. In the present embodiment, a third temperature sensor 73 is provided at the condenser 40, the third temperature sensor 73 is connected to the ice making controller 70, and the third temperature sensor 73 is used to detect the temperature of the condenser 40 and can feed back the detected temperature of the condenser 40 to the ice making controller 70.

When the temperature of the condenser 40 is higher than the fifth preset value, the ice making controller 70 controls the water draining solenoid valve 75 to be opened, and the temperature of the condenser 40 is reduced by draining water to the condenser 40, so that the ice making efficiency is prevented from being affected due to heat accumulation of the condenser 40. When the temperature of the condenser 40 is lower than the sixth preset value, the ice-making controller 70 controls the water discharge solenoid valve 75 to be closed, thereby reducing the loss of cold energy of the water stored in the water pan 10, and reducing the temperature of the water discharged from the condenser 40 when the heat is accumulated at the condenser 40. The fifth preset value is greater than the sixth preset value, and the fifth preset value is generally less than the third preset value. The fifth preset value may be set to 55 deg.c and the sixth preset value may be set to 35 deg.c.

It can be appreciated that the first preset value, the second preset value, the third preset value, the fourth preset value, the fifth preset value, and the sixth preset value may be adjusted according to actual ice making requirements. The ice making apparatus may further be provided with a first temperature sensor 71, a second temperature sensor 72, and a third temperature sensor 73 at the same time, so that the ice making controller 70 can control the opening and closing of the drain solenoid valve 75 according to the combination of the water storage temperature of the water receiving tray 10, the discharge temperature of the compressor, and the temperature of the condenser 40. If any one of the conditions that the water storage temperature of the water receiving tray 10 is lower than the first preset value, the discharge temperature of the compressor is higher than the third preset value, and the temperature of the condenser 40 is higher than the fifth preset value is satisfied, the ice making controller 70 controls the water discharge solenoid valve 75 to be opened. When the water storage temperature of the water receiving tray 10 is higher than the second preset value, the discharge temperature of the compressor is lower than the fourth preset value, and the temperature of the condenser 40 is lower than the sixth preset value, the ice making controller 70 controls the discharge solenoid valve 75 to be closed.

In order to facilitate water replenishment into the water tray 10, the ice making apparatus is further provided with a water replenishment line for replenishing the water tray 10 with water. In order to provide convenience in water replenishment, a water replenishment valve 76 may be provided in the water replenishment pipeline, the water replenishment valve 76 being connected to the ice making controller 70, the water replenishment valve 76 being controlled to be opened and closed by the ice making controller 70. The ice-making controller 70 may control the water-replenishing valve 76 to be opened when the water-discharging solenoid valve 75 is controlled to be opened or after a preset time is opened, and control the water-replenishing valve 76 to be closed when the water storage temperature in the water-receiving tray 10 is higher than a second preset value.

In addition, a liquid level sensor 74 may be further disposed on the water pan 10, and the liquid level of the water stored in the water pan 10 is detected by using the liquid level sensor 74 and fed back to the ice-making controller 70, so that the ice-making controller 70 can combine with the liquid level of the water pan 10 to comprehensively control the opening and closing of the water-supplementing valve 76. During the continuous ice making process, when the water storage liquid level in the water receiving tray 10 is lower than the liquid level lower limit, the ice making controller 70 controls the water supplementing valve 76 to be opened; when the water level in the drip tray 10 is above the upper level limit, the ice making controller 70 controls the water replenishment valve 76 to close. When the water storage in the water receiving tray 10 is required to be completely discharged after ice making is completed, the water supplementing solenoid valve 76 still keeps a closed state when the water level of the water receiving tray 10 is lowered to the lower limit of the water level due to the opening of the water draining solenoid valve 75.

The ice is removed after the completion of the ice making so that the frozen ice cubes are separated from the grid of the ice making film 20. In order to improve the ice removing efficiency, referring to fig. 1 and 3, the ice making apparatus provided in the embodiment of the present application further includes an ice removing pipeline 60, where the ice removing pipeline 60 is disposed between the ice making film 20 and the evaporator in a bonding manner, and can exchange heat between the water and the ice making film 20, that is, the ice removing pipeline 60 is disposed on the back side of the ice making film 20 facing away from the ice grid. In the ice making process, the ice removing pipeline 60 is in a non-water-passing state, so that the heat absorption of the ice making film 20 is not influenced, and the ice removing pipeline 60 is not blocked. When the ice is collected after the ice making is completed, the ice removing pipeline 60 is used for conveying the normal-temperature water to the back side of the ice making film 20, and the normal-temperature water exchanges heat with the ice making film 20 through the ice removing pipeline 60, so that the temperature of the ice making film 20 is increased, and the ice cubes are promoted to fall off.

The water distribution assembly 30 comprises a water distributor arranged above the ice making film 20 and a water distribution pipeline connected with the water distributor. The water receiving tray 10 is provided with a water pump, a water inlet of the water pump is connected with the water receiving tray 10, and a water outlet of the water pump is respectively provided with a water distribution pipeline, an ice removing pipeline 60 and a first end or a water inlet of the drainage pipeline 50 so as to pump water to the water distribution pipeline, the ice removing pipeline 60 and the drainage pipeline 50 respectively. The water distribution pipeline can be provided with a water distribution electromagnetic valve, the ice removing pipeline 60 can be provided with an ice removing electromagnetic valve 77, and the water distribution electromagnetic valve and the ice removing electromagnetic valve 77 are connected with the ice making controller 70 so that the ice making controller 70 controls the water distribution electromagnetic valve, the water drainage electromagnetic valve 75 and the ice removing electromagnetic valve 77 to be opened alternately.

When ice making starts, the ice making controller 70 controls the water distribution electromagnetic valve and the water pump to start water distribution to the ice making film 20, and the water receiving disc 10 recovers low temperature water flowing from the ice making film 20; during the ice making process, the ice making controller 70 controls the opening or closing of the water discharge solenoid valve 75 according to the operation state of the ice making apparatus, such as the water storage temperature of the water receiving tray 10, the discharge temperature of the compressor, the temperature of the condenser 40, etc.; after the ice making is completed, the ice making controller 70 controls the water draining electromagnetic valve 75 to be opened, empties the water in the water receiving disc 10 and closes the water draining electromagnetic valve 75; then the water supplementing valve 76 is opened, the water supplementing pipeline supplements the water receiving disc 10 with the warm water, the ice removing electromagnetic valve 77 is opened, the water pump pumps the normal-temperature water in the water receiving disc 10 to be conveyed to the ice removing pipeline 60, and the heat exchange is carried out between the warm water and the ice making ice film 20, so that ice cubes are promoted to be separated from the ice making ice film 20. It will be appreciated that the de-icing line 60 and the water make-up line may also be connected as desired.

The embodiment of the application also provides an ice making method, which is suitable for the ice making device provided in the above embodiment, as shown in fig. 5, wherein the ice making method includes an ice making control mode, and the ice making control mode includes:

Step S10: distributing water to the ice making film 20 for making ice, and recycling low-temperature water falling from the ice making film 20 by utilizing the water receiving tray 10;

step S20: the condenser 40 of the ice making apparatus is cooled by discharging the low temperature water.

In the above-mentioned ice making method, the water receiving tray 10 is utilized to recycle the low-temperature water sprayed to the ice making film 20 by the water distribution component 30, and the low-temperature water which is not frozen and flows down from the ice making film 20 is recycled; the low-temperature water in the water receiving tray 10 is discharged to the condenser 40 of the refrigeration equipment, so that the condenser 40 is cooled, the heat release efficiency of the refrigerant in the condenser 40 is improved, the heat exchange efficiency of the refrigerant at the evaporator and the ice making film 20 is further improved, and the ice making efficiency is improved; the heat of the condenser 40 is prevented from corresponding to the environment temperature greatly increased caused by the condenser 40, and the use experience of a user is prevented from being influenced. Compared with the method that the low-temperature water in the water receiving tray 10 is directly discharged after the ice making is finished, the waste of the low-temperature water cooling capacity is avoided.

In the continuous ice making mode, the low-temperature water in the water receiving tray 10 is sent to the ice making film 20 again, so as to avoid the influence of the low-temperature water forming ice slag in the water receiving tray 10 on the water distribution efficiency, increase the water distribution energy consumption, and by discharging part of the low-temperature water out of the water receiving tray 10 and supplementing a certain normal-temperature water to the water receiving tray 10, the water temperature of the water sprayed to the ice making film 20 is improved to a certain extent, but the overall energy consumption of ice making is reduced due to the reduction of the water distribution energy consumption and the increase of the heat exchange efficiency of the condenser 40, and the ice making efficiency is improved.

Referring to fig. 6, in the ice making method according to an embodiment of the present application, the step of discharging low-temperature water to cool the condenser 40 of the ice making apparatus in step S20 includes:

Step S201: detecting the water temperature of the low-temperature water recovered in the water receiving tray 10;

step S202: judging whether the water temperature is lower than a first preset temperature or not;

step S203: if so, the low-temperature water in the drip tray 10 is discharged to the surface of the condenser 40.

In the ice making control method, by detecting the water temperature of the low-temperature water in the water receiving tray 10, the low-temperature water in the water receiving tray 10 is discharged when the temperature in the water receiving tray 10 is lower than the first preset value, ice slag in the water receiving tray 10 is avoided, meanwhile, the discharged low-temperature water is utilized to cool the condenser 40, heat accumulation of the condenser 40 is avoided, the cooling efficiency of the evaporator on the ice making film 20 is influenced, the ice making efficiency is further influenced, and the overlarge environmental temperature rise caused by the condenser 40 is also avoided. Specifically, a first temperature sensor 71 may be disposed in the water pan 10, the first temperature sensor 71 is used to detect the water temperature of the low-temperature water in the water pan 10, and then the corresponding drainage solenoid valve 75 is controlled to be opened or closed according to the detected water temperature, wherein the drainage solenoid valve 75 is a solenoid valve for controlling drainage to the condenser 40. When the detected water temperature is lower than the first preset value, the water discharge solenoid valve 75 is opened, and water is replenished to the water receiving tray 10; when the detected water temperature is higher than the second preset value, the drain solenoid valve 75 is controlled to close to stop draining. The second preset value is greater than the first preset value, which may be 2 ℃, and the second preset value may be 15 ℃.

Referring to fig. 7, in the ice making method according to an embodiment of the present application, the step of discharging low-temperature water to cool the condenser 40 of the ice making apparatus in step S20 includes:

step S204: detecting the exhaust temperature of the compressor;

Step S205: judging whether the exhaust temperature is higher than a third preset value;

Step S206: if so, the low-temperature water in the drip tray 10 is discharged to the surface of the condenser 40.

In the above ice making control method, by detecting the exhaust temperature in the compressor, when the exhaust temperature is higher than the third preset value, the low-temperature water in the water receiving tray 10 is discharged, the discharged low-temperature water is used for cooling the condenser 40, so that the heat accumulation of the condenser 40 is avoided, the cooling efficiency of the evaporator on the ice making film 20 is influenced, the ice making efficiency is further influenced, and the overlarge environmental temperature rise caused by the condenser 40 is avoided.

The exhaust temperature can reflect the heat exchange load of the refrigerant in the condenser 40 to a certain extent, and the exhaust temperature is too high, so that the heat exchange load of the refrigerant in the condenser 40 is large, the temperature of the condenser 40 is easily increased, and the heat exchange efficiency of the refrigerant in the condenser 40 is easily reduced. When the exhaust temperature is lower than the fourth preset value, that is, when the heat exchange load of the refrigerant in the condenser 40 is small, the drain solenoid valve 75 may be closed to stop the drain cooling of the condenser 40. The fourth preset value is less than the third preset value, which may be 70 ℃, and the fourth preset value may be 50 ℃. Specifically, a second temperature sensor 72 may be provided at the discharge port of the compressor, and the discharge temperature of the compressor may be detected by the second temperature sensor 72.

Referring to fig. 8, in the ice making method according to an embodiment of the present application, the step of discharging low-temperature water to cool the condenser 40 of the ice making apparatus in step S20 includes:

step S207: detecting the temperature of the condenser 40;

Step S208: judging whether the temperature of the condenser 40 is higher than a fifth preset value;

Step S209: if so, the low-temperature water in the drip tray 10 is discharged to the surface of the condenser 40.

In the above ice making control method, by directly detecting the temperature of the condenser 40, when the temperature of the condenser 40 is higher than the fifth preset value, the low-temperature water in the water receiving tray 10 is discharged, the discharged low-temperature water is used for cooling the condenser 40, so that the heat accumulation of the condenser 40 is avoided, the cooling efficiency of the evaporator on the ice making film 20 is influenced, the ice making efficiency is further influenced, and the excessive environmental temperature rise of the condenser 40 is avoided.

When the temperature of the condenser 40 is too high, the heat exchange efficiency of the refrigerant in the condenser 40 is reduced, and the condenser 40 needs to be drained to cool. When the temperature of the condenser 40 is lower than the sixth preset value, the drain solenoid valve 75 may be closed to stop the drain cooling of the condenser 40. The sixth preset value is less than the fifth preset value, which may be 55 ℃, and the sixth preset value may be 35 ℃. Specifically, a third temperature sensor 73 may be provided at the condenser 40, and the discharge temperature of the compressor may be detected by the third temperature sensor 73.

Referring to fig. 9, an embodiment of the present application provides an ice making control method, in which the water temperature of the water tray 10, the discharge temperature of the compressor, and the temperature of the condenser 40 can be simultaneously detected before the water discharge solenoid valve 75 controlling the water tray 10 to discharge water to the condenser 40 is opened to discharge water to the condenser 40, and the water discharge solenoid valve 75 is controlled to be opened and closed based on the detected water temperature, the discharge temperature of the compressor, and the temperature of the condenser 40. When any one of the water temperature of the water pan 10 is lower than the first preset value, the exhaust temperature of the compressor is lower than the third preset value, or the temperature of the condenser 40 is lower than the fifth preset value, the water discharge solenoid valve 75 is opened to discharge water to the condenser 40 for cooling.

Specifically, the water supplementing electromagnetic valve 76 can be opened, the water with the temperature being equal to that of the water receiving disc 10 is introduced, the water pump is started, the ice removing electromagnetic valve 77 is opened, the water at the normal temperature of the water receiving disc 10 is pumped by the water pump, and the water is sent to the ice making film 20 through the ice removing pipeline 60 to exchange heat with the ice making film 20.
