Abstract

The application relates to a condensing device and a dish washer. The condensing device comprises a condensing mechanism and a condensed water discharger. A condensing channel is formed in the condensing mechanism, and an air inlet and an air outlet which are communicated with the condensing channel are formed. The condensed water discharger is arranged on the condensing mechanism and is used for discharging condensed water formed in the condensing channel outwards.

Referring to fig. 1 to 4, a condensing device 100 for a dishwasher 200 includes a condensing mechanism 10 and a condensed water drain 30 is provided in an embodiment of the present application. The condensing mechanism 10 has a condensing passage N formed therein, and an air inlet 11 and an air outlet 13 communicating with the condensing passage N. The condensed water drain 30 is provided to the condensing mechanism 10 for discharging condensed water formed in the condensing passage N outwardly.

It will be appreciated that the condensing device 100 is provided outside the main machine 210 of the dishwasher 200, and may be provided in particular at a side wall of the main machine 210. The main machine 210 of the dishwasher 200 forms a dish washing space and performs a dish washing function, and in order to achieve the normal function, the main machine 210 may include a liner assembly, a water cup assembly, a spray arm assembly, a filter assembly, a washing pump, a drainage pump, a pipeline, an air pump, etc., which are not described herein.

In use, the condensing mechanism 10 communicates with the interior of the dishwasher 200, i.e., the dishwashing space within the main machine 210, via the air inlet 11 and the air outlet 13. The gas in the dish washer 200 is rich in ozone, steam and the like due to the effect of the ion generating device, and can enter the condensing mechanism 10 through the air inlet 11, the steam content is reduced after the gas is condensed by the condensing mechanism 10, and the gas returns into the dish washer 200 through the air outlet 13, so that ozone generated by ionization is fully utilized for sterilization. The air inlet 11 of the condensation mechanism 10 may be arranged lower in height than the air outlet 13 thereof.

The power of the air flow in the dishwasher 200 may be generated by an air pump in the main unit 210 or by the pressure difference between the condensing mechanism 10 and the air in the dishwashing space. In addition, the condensing device 100 may further include a driving air pump provided in the condensing mechanism 10, and the driving air pump provides power for air flowing in the dish washer 200, so that air flows from the air inlet 11 into the condensing mechanism 10 from the dish washing space, and flows from the air outlet 13 into the dish washing space from the condensing mechanism 10.

The condensate drain 30 is a steam trap and is configured to block steam drainage, i.e., to block gas from being discharged therethrough while being able to drain liquid condensate.

In use of the condensing device 100, the condensing mechanism 10 receives air from within the dishwasher 200 through the air inlet 11. Because the steam sterilizing or plasma generating device is required to work to generate steam, the steam content of the gas in the dishwasher 200 is high, and after entering the condensing mechanism 10 through the air inlet 11, the gas is condensed in the condensing mechanism 10 to generate condensed water, so that the steam content of the gas is reduced, and the condensed water is discharged through the condensed water discharger 30. In this way, the steam of the air in the dishwasher 200 is controlled, which helps to reduce the probability of condensation occurring in the dishwasher 200, thereby improving the efficiency of plasma generation and overcoming the problems of bacterial growth caused by humidity.

Referring to fig. 5 and 6, further, the condensing mechanism 10 includes a first condensing housing 151 and a second condensing housing 153, and the first condensing housing 151 and the second condensing housing 153 are connected and surrounded to form a condensing channel N.

In this way, the condensation channel N formed by the first condensation housing 151 and the second condensation housing 153 can be manufactured by simple splicing, so that the manufacturing efficiency is high, the cost is low, and the manufacturing of the internal structure of the condensation mechanism 10 is convenient.

In some embodiments, further, the condensation mechanism 10 is configured with a plurality of water blocking ribs 17 arranged in a staggered manner therein, and the plurality of water blocking ribs 17 form a meandering condensation channel N. It is understood that the first condensation housing 151 and the second condensation housing 153 may form the water blocking rib 17, and the water blocking rib 17 may extend obliquely.

The water blocking ribs 17 can guide the air flow in the condensing mechanism 10 to flow so as to form a meandering condensing channel N, so that the distance of the condensing channel N is prolonged, and the air flow is sufficiently condensed and dried. In addition, the water retaining ribs 17 can also improve heat exchange efficiency and accelerate condensation drying. The condensed water is formed in a large amount on the water blocking rib 17 and flows along the water blocking rib 17.

Further, the condensing mechanism 10 includes a first inner wall 155 and a second inner wall 157 disposed opposite to each other. There are two adjacent water blocking ribs 17, one of which forms an air passage Q spaced from the first inner wall 155 and the other of which forms an air passage Q spaced from the second inner wall 157.

In use, the first inner wall 155 of the condensing mechanism 10 may be positioned below and the second inner wall 157 positioned above. There are two adjacent water blocking ribs 17, and two water blocking ribs 17 partially adjacent to each other may be provided, or any two water blocking ribs 17 may be provided. The overair passage Q is used for the continuous flow of the air flow bypassing the blocking of the water deflector 17.

In this way, the adjacent water blocking ribs 17 can form the air passage Q alternately in the up-down direction, that is, the condensation passage N extending in a meandering manner.

In some embodiments, the water blocking rib 17, which forms the overgas passage Q spaced from the first inner wall 155, forms the overliquid passage spaced from the second inner wall 157.

Since the condensed water flows downward along the water blocking rib 17, the liquid passing channel formed at a distance from the second inner wall 157 can straighten the blocking of the condensed water passing through the water blocking rib 17, flow and gather, and then all flow to the condensed water drain 30.

In some embodiments, water blocking ribs 17, which form the gas passage Q at intervals from the second inner wall 157, are connected to the first inner wall 155.

The water blocking rib 17 forming the gas passing channel Q is spaced from the second inner wall 157, and the gas passing channel Q can simultaneously take on the function of the liquid passing channel without forming an additional liquid passing channel, and the water blocking rib 17 is connected with the first inner wall 155 to prevent gas from directly passing therethrough, so that tortuous flow cannot be formed.

In some embodiments, the condensing mechanism 10 is configured with a deflector rib 19 therein, the deflector rib 19 being used to direct condensed water formed in the condensing channel N to the condensed water drain 30.

The guide rib 19 may be connected to the second inner wall 157 of the condensing unit 10 to guide the condensed water flowing along the second inner wall 157 to the condensed water discharger 30 together, thereby improving drainage efficiency.

In some embodiments, the condensing device 100 further includes a heat dissipation mechanism 50, where the heat dissipation mechanism 50 is disposed on the condensing mechanism 10.

The heat dissipation mechanism 50 may be disposed in the condensation mechanism 10, or may be disposed on a surface of the condensation mechanism 10, for dissipating heat from the condensation mechanism 10, and may specifically dissipate heat from the condensation mechanism 10 by means of air cooling, water cooling, or the like.

The condensing mechanism 10 releases latent heat of the steam during condensation, which may cause an increase in temperature thereof to affect condensation efficiency. The heat dissipation mechanism 50 can take away the heat of the condensing mechanism 10, so as to improve the condensing and drying efficiency.

Further, the heat dissipation mechanism 50 includes an air duct housing 51 and a fan 53, a cooling air duct is formed in the air duct housing 51, and the fan 53 is used for driving airflow in the cooling air duct to flow.

The air duct housing 51 forms an air inlet and an air outlet communicating with the cooling air duct, the air duct housing 51 forms a mounting housing 511 at the air inlet, and the fan 53 is used for driving air flow from the air inlet to the air outlet.

The heat dissipation mechanism 50 dissipates heat by air cooling, and the fan 53 can effectively improve the strength of convection heat exchange and enhance the heat dissipation effect. In addition, the air duct case 51 may be formed with air cooling fins to improve heat dissipation.

Specifically, the heat dissipation mechanism 50 further includes a blocking cover 55, where the blocking cover 55 is disposed at a connection portion between the fan 53 and the air duct housing 51, and is used for guiding airflow into the cooling air duct from the air inlet.

Further, the air duct housing 51 is covered on one side of the condensing mechanism 10, and forms a cooling air duct together with the outer surface of the condensing mechanism 10.

In this way, the air flowing in the cooling air duct can naturally and directly exchange heat with the outer surface of the condensation structure.

In some embodiments, the air duct housing 51 is configured with air guide ribs 513 on an inner surface facing the cooling air duct.

It will be appreciated that the air rail 513 extends generally along the air inlet to the air outlet. The air guiding rib 513 is used for guiding the cooling air blown out by the fan 53 to flow in the cooling air duct so as to fully flow through the cooling air duct to exchange heat with the condensing mechanism 10.

Further, the air duct case 51 is configured with a plurality of air guide ribs 513, and the air guide ribs 513 are arc-shaped, and at least two air guide ribs 513 are arranged side by side and spread.

Of all the air guide ribs 513, at least some of the air guide ribs 513 are arranged side by side in the flow direction of the cooling air blown out from the fan 53 and are extended in a diffusing manner. The diffusion extension means that the distance between the ends of the air guide ribs 513, which are arranged side by side, near the air inlet is smaller than the distance between the ends of the air guide ribs, which are arranged near the air outlet.

The arc-shaped air guide ribs 513 can disturb the cooling air blown by the fan 53, so that the cooling air is diffused around the cooling air channel, and the cooling air is beneficial to taking away the heat of the condensing mechanism 10, thereby improving the condensing efficiency.

In some embodiments, the condensing device 100 further includes a rib 70, where the rib 70 is disposed on an outer surface of the air duct housing 51 facing away from the condensing mechanism 10, and is used to connect with a side wall of the main machine 210 of the dishwasher. The condensing unit 100 is provided on a side wall of the main unit 210 through a side provided with the rib 70.

The rib 70 can block between the air duct shell 51 and the main unit 210, thereby avoiding close adhesion between the air duct shell and the main unit 210, reducing heat exchange between the air duct shell and the main unit, and avoiding heat generated by the main unit 210 from interfering with cooling effect of the condensing mechanism 10.

In some embodiments, the heat sink mechanism 50 further includes a temperature sensor (not shown) disposed within the dishwasher 200 or within the condensing mechanism 10 and in communicative connection with the blower 53, the blower 53 determining the rotational speed based on temperature parameters measured by the temperature sensor.

The temperature sensor is used to detect the temperature in the dishwasher 200 (in the main machine 210) or in the condensing mechanism 10, and is capable of reacting to the temperature of the steam, and the higher the steam temperature is, the greater the heat content of the steam is, and the greater the difficulty in continuous condensation. It will be appreciated that the rotational speed of the blower 53 is positively correlated to the magnitude of the temperature parameter measured by the temperature sensor.

Thus, the higher the steam temperature, the higher the intensity of the cooling air blown by the blower 53 is to relieve the condensing pressure and improve the condensing effect. Different fan 53 rotating speeds are controlled according to different temperatures, so that the minimum energy consumption is realized while the heat exchange efficiency is ensured.

Specifically, the condensing device 100 may further include a control board and a power module, the temperature sensor is in communication connection with the control board, the temperature parameter measured by the temperature sensor is transmitted to the control board, the control board will give the power module matching information of the temperature parameter, and the power module adjusts the power frequency to control the rotation speed of the fan 53.

Referring to fig. 7, in some embodiments, the condensate drain 30 includes a main body 31, a first channel 311 and a second channel 313 are formed in the main body 31, and the first channel 311 is communicated with the top of the second channel 313. The main body 31 is constructed with a drain water inflow structure 315 communicating with the condensation passage N at the bottom of the first passage 311. The body 31 is configured with a drain port 3131 in the second passage 313.

The first channel 311 and the second channel 313 are separated by the partition 37, and only the top communication is maintained, in other words, the two channels together form an inverted U-shaped channel. The main body 31 communicates with the condensation passage N through a drain water inflow structure 315 located at the bottom of the first passage 311, and drains through a drain outlet 3131 located at the second passage 313, and the drain outlet 3131 may be configured to be in communication with the bottom of the second passage 313. It is understood that top and bottom refer to the top and bottom in the height direction of the condensing unit 100 when in use.

The condensed water needs to flow in from the bottom of the first channel 311 and, when accumulated to a sufficient height, can pass over the partition 37 from the top of the first channel 311 into the second channel 313 and then be discharged from the second channel 313. Wherein the flow direction of the condensed water is shown by the arrow in fig. 7.

In this way, the float 33 is not needed, and only a part of water is needed to be reserved at the bottom of the first channel 311, so that a liquid seal can be formed by passing through the communication port between the drainage water inlet structure 315 and the condensation channel N, and gas cannot leak. The condensed water is normally discharged through the second passage 313 by accumulating only to a height higher than the partition 37. At this time, since the first passage 311 is filled with condensed water, a stable liquid seal can be formed, reducing the probability of gas entering the second passage 313 from the first passage 311.

Referring to fig. 7 and 8, in other embodiments, the condensate drain 30 includes a main body 31 and a float 33 disposed in the main body 31, wherein the main body 31 is communicated with the condensate channel N and is configured with a drain port 3131; the float 33 changes the connection and disconnection between the drain port 3131 and the condensation passage N by floating and sinking.

It will be appreciated that the float 33 is less dense than water and can be in a floating or sinking state, respectively, depending on the level at which it is located. Wherein the float 33 having a density less than that of water means that the entire density thereof is less than that of water, and may be made of a material having a density less than that of water or a material having a density greater than that of water, and the condition that the entire density is less than that of water is satisfied by forming a partial cavity.

The main body 31 may be formed on the condensation mechanism 10, and communicate with the condensation channel N through the drain-water inlet structure 315, and can accommodate a certain amount of condensed water therein. The float 33 is configured to float up to communicate the drain port 3131 with the condensation passage N when the water level of the condensed water in the main body 31 or the condensed water communicated with the main body 31 is higher than a set value, and to sink down to block the communication of the drain port 3131 with the condensation passage N when the water level of the condensed water in the main body 31 is lower than the set value. In other words, the float 33 is blocked between the drain port 3131 and the condensation channel N, and may be used to directly block the drain port 3131 or to block the drain water inlet structure 315, and when the condensed water accumulates to a certain extent, the buoyancy generated by the float is enough to support the float 33, so that the float is not blocked, and the drain port 3131 is restored to be in communication with the condensation channel N.

When condensate is not formed or accumulated insufficiently, the float 33 may function to close the drain port 3131 to reduce the possibility of leakage of gas containing ozone or the like in the condensation passage N from the drain port 3131. When the condensed water is accumulated to a certain extent and the float 33 can float, it is explained that the condensed water itself can drain through the drain port 3131 and form a certain liquid seal to the drain port 3131, which contributes to reducing the possibility of leakage of the gas containing the ozone and other components in the condensation passage N from the drain port 3131.

Further, a first channel 311 and a second channel 313 are formed in the main body 31, and the top of both the first channel 311 and the second channel 313 are communicated. The main body 31 is provided with a drainage water inlet structure 315 communicated with the condensation channel N at the bottom of the first channel 311, the main body 31 is communicated with the condensation channel N through the drainage water inlet structure 315, and the float 33 is arranged in the first channel 311 and seals the drainage water inlet structure 315 when in a sinking state. The drain port 3131 is configured in the second channel 313.

The first channel 311 and the second channel 313 are separated by the partition 37, and only the top communication is maintained, in other words, the two channels together form an inverted U-shaped channel. The main body 31 communicates with the condensation passage N through a drain water inflow structure 315 located at the bottom of the first passage 311, and drains through a drain outlet 3131 located at the second passage 313, and the drain outlet 3131 may be configured to be in communication with the bottom of the second passage 313. It is understood that top and bottom refer to the top and bottom in the height direction of the condensing unit 100 when in use.

The condensed water needs to flow in from the bottom of the first channel 311 and, when accumulated to a sufficient height, can pass over the partition 37 from the top of the first channel 311 into the second channel 313 and then be discharged from the second channel 313. Wherein the flow direction of the condensed water is shown by the arrow in fig. 7.

The drain water inlet structure 315 communicates with the condensation passage N, and is formed with a drain water inlet J communicating with the first passage 311. The float 33 is provided above the drain water inflow structure 315, is capable of floating in the first passage 311, and forms a separable engagement with the drain water inlet J by floating upward. The float 33 is used to block the drain water inlet J, and when condensate water accumulates to create buoyancy to the float 33 to lift the float 33 up, the float 33 loses the block of the drain water inlet J.

In this way, when condensate is not formed or is not accumulated sufficiently, the float 33 can seal the drain inlet 315, reducing the possibility of leakage from the condensate passage N. When the condensed water is accumulated to a sufficient height, it can be normally discharged through the second passage 313. At this time, since the first passage 311 is filled with condensed water, a stable liquid seal can be formed, reducing the probability of gas entering the second passage 313 from the first passage 311.

In some embodiments, the gap between the float 33 and the peripheral side inner wall of the first passage 311 is L, and 0.5 mm.ltoreq.L.ltoreq.1 mm.

It will be appreciated that the size of L may be adapted to the size of the float 33, and is not particularly limited herein.

The gap between the float 33 and the peripheral side inner wall of the first passage 311 is controlled, so that the float 33 can be supported and limited when the float 33 floats in the first passage 311, and the float 33 is prevented from being excessively deviated to cause that the float cannot be aligned and matched with the drain water inlet J after re-sinking.

In some embodiments, the end of the float 33 that mates with the drain water inlet J is configured as a cone.

The tapered end portion can exert a guiding effect during sinking of the float 33 so that it can be accurately fitted to the drain water inlet J.

In some embodiments, the body 31 further includes a stopper 35, the stopper 35 being provided on top of the first channel 311, the stopper 35 being located on a floating path of the float 33 for limiting the float 33.

It will be appreciated that the stop 35 is located within the first channel 311, within the second channel 313, or at the interface of the first channel 311 and the second channel 313.

The stopper 35 can limit the floating height of the float 33, prevent it from excessively floating, and make its floating range excessively large, to reduce the probability of misalignment caused thereby.

Further, the stopper 35 is blocked at the top of the first passage 311 and is configured with an overflow port Y communicating the first passage 311 with the second passage 313, and a surface of the stopper 35 facing the first passage 311 is configured with a stopper protrusion 351.

The stopper 35 penetrates through the overflow port Y in the height direction, and when the condensed water in the first channel 311 is accumulated to the top and further increases, the condensed water can overflow to the second channel 313 through the overflow port Y to be discharged. The stopper protrusion 351 can prevent the float 33 from floating to block the overflow port Y.

Further, the surface of the stopper 35 facing away from the first passage 311 is configured as a part of the inner wall of the second passage 313, and is configured as an inclined surface inclined toward the side where the drain port 3131 is located.

The inclined surface can guide the condensed water overflowed from the overflow port Y to flow toward the drain port 3131 in an inclined direction.

In the condensing device 100, the air in the main machine 210 of the dish washer 200 is introduced into the condensing channel N from the air inlet 11, condensed, and then guided back into the main machine 210 from the air outlet 13, thereby completing the drying of the main machine 210. In this process, the fan 53 blows cooling air into the cooling air duct formed by the air duct case 51 to cool the condensing mechanism 10, and the air speed of the fan 53 is adjusted according to the detection data of the temperature sensor. The condensed water generated by the condensation of the condensation mechanism 10 gradually converges along the water passage S and reaches the condensed water discharger 30. When the condensed water is insufficient, the float 33 and the condensed water cooperate to well block the water drain inlet J, block the communication between the water drain outlet 3131 and the condensation channel N, and prevent the gas in the condensation channel N from leaking. When the condensed water is accumulated to a certain extent, the float 33 can be lifted, the drain water inlet J is opened, and overflows from the overflow port Y at the top of the first passage 311, enters the second passage 313, and is further discharged from the second passage 313.
