[0036] See also Figures 1 to 8 The washing appliance 100 of the embodiment of the present invention comprises a cavity 10, a door 20, an air duct system 30 and an air conditioning system 50. The cavity 10 is formed with a washing chamber 11, the door 20 can be pushed and pulled connected to the cavity 10 to open or close the washing chamber 11, the air duct system 30 is formed with an air duct 31, and the air outlet 311 of the air duct 31 is connected to the outside atmosphere. The air conditioning system 50 comprises a first heat exchange device 51 and a heat storage structure 55, the first heat exchange device 51 is arranged in the air duct 31 of the air duct system 30, the first heat exchange device 51 is thermally connected to the heat storage structure 55, and the first heat exchange device 51 is used to perform heat exchange with the airflow entering the air duct 31 so that the heat of the airflow after heat exchange is stored in the heat storage structure 55.

[0037] In the washing appliance 100 of the embodiment of the present invention, the cold air formed by the outside air exchanging heat with the first heat exchange device 51 can be exported to the outside atmosphere, and the heat storage structure 55 can store the heat of the airflow after heat exchange. In this way, the washing appliance 100 has a refrigeration capacity, which can meet the refrigeration needs of users when they are in the kitchen, and improve the user experience. At the same time, the heat generated during the refrigeration process is stored by the heat storage structure 55, avoiding the waste of heat.

[0038] Please combine Figure 1 , Figure 2 and Figure 7 In this embodiment, the air-conditioning system 50 also includes a compressor 52, a second heat exchange device 53 and a throttling device 54. The first heat exchange device 51, the compressor 52, the second heat exchange device 53 and the throttling device 54 are connected in sequence to form a closed refrigerant circuit, and the heat storage structure 55 is used for heat exchange with the second heat exchange device 53.

[0039] When the washing appliance 100 is used for cooling, the air conditioning system 50 is turned on, and the refrigerant in the refrigerant circuit is compressed into a high-temperature and high-pressure gas by the compressor 52, and then the refrigerant is transported from the compressor 52 to the second heat exchange device 53, and the high-temperature and high-pressure gas is liquefied into a low-temperature and high-pressure liquid in the second heat exchange device 53, and the low-temperature and high-pressure liquid becomes a gas-liquid two-phase in a low-temperature and low-pressure state after passing through the throttling device 54, and then enters the first heat exchange device 51 to absorb heat to form a low-temperature and low-pressure gas, and then the low-temperature and low-pressure gas in the first heat exchange device 51 enters the compressor 52 for compression again, and enters the next cycle. It can be understood that the heat absorbed by the refrigerant flowing through the first heat exchange device 51 comes from the heat transferred to the first heat exchange device 51 by the airflow entering the air duct 31. In this process, the airflow entering the air duct 31 transfers heat to the first heat exchange device 51 to form cold air, which is then introduced into the outside atmosphere to achieve a cooling effect.

[0040] It can be understood that in this embodiment, the heat storage structure 55 is used to perform heat exchange with the second heat exchange device 53, which specifically means that the high-temperature and high-pressure gas releases heat when it is liquefied in the second heat exchange device 53, and the heat storage structure 55 stores the heat released by the second heat exchange device 53. When the following embodiments have similar explanations and descriptions, they can also be understood by referring to the explanations here.

[0041] In addition, it should be noted that, in this embodiment, the thermal connection between the first heat exchange device 51 and the heat storage structure 55 means that the first heat exchange device 51 transfers heat to the refrigerant in the refrigerant pipeline, and then the refrigerant is compressed in the compressor 52 and finally transfers the heat to the heat storage structure 55 in the second heat exchange device 53. When the following embodiments have similar explanations and descriptions, they can also be understood by referring to the explanations here.

[0042] In this embodiment, the compressor 52 can be a horizontal compressor or a vertical compressor, the first heat exchange device 51 can be an evaporator, the evaporator can be a tube-fin evaporator or a microchannel evaporator, and the second heat exchange device 53 can be a condenser or a condenser tube. There is no specific limitation and it can be determined according to actual conditions.

[0043] See also Figure 1 and Figure 7In this embodiment, the washing appliance 100 also includes a washing system 60, which includes a washing pump 62, a water collection tank 61 and a spray arm assembly 63. The washing pump 62 is connected to the water collection tank 61 and the spray arm assembly 63 through a pipeline 64, respectively. The spray arm assembly 63 is arranged in the washing chamber 11, and the washing pump 62 is used to pump the washing water in the water collection tank 61 to the spray arm assembly 63.

[0044] In some embodiments, the second heat exchange device 53 is disposed in the heat storage structure 55, and the heat storage structure 55 may be a phase change heat storage structure module, and the heat storage structure 55 includes a phase change heat storage material, that is, the heat storage structure 55 uses the phase change heat storage material as a heat storage medium. The second heat exchange device 53 is disposed in the phase change heat storage structure module and is thermally connected to the phase change heat storage material, and the phase change heat storage material can store the heat exchanged with the second heat exchange device 53, and the pipeline 64 of the washing system 60 passes through the heat storage structure 55 and contacts with the phase change heat storage material, and the heat storage structure 55 can also exchange heat with the washing water in the pipeline 64.

[0045] Specifically, when washing with the washing appliance 100, the washing system 60 is turned on, and the washing pump 62 continuously circulates the washing water in the sump 61 to the various spray arms of the spray arm assembly 63, thereby achieving the purpose of cleaning the items. When there is no need to heat the washing water, the washing water can be controlled by a valve not to flow through the heat storage structure 55, and directly transported to the spray arm assembly 63. When it is necessary to heat the washing water, the washing water is controlled by a valve to flow through the heat storage structure 55. Since the phase change heat storage material in the heat storage structure 55 will store heat when the air-conditioning system 50 is working, when the washing water flows through the heat storage structure 55, the phase change heat storage material in the heat storage structure 55 will release heat to heat the washing water, and then it will be sent to the various spray arms of the spray arm assembly 63 to wash the items in the washing chamber 11 with hot water. Figure 1 and Figure 7 In the example shown, the spray arm assembly 63 has only one spray arm. In other embodiments, the number of spray arms of the spray arm assembly 63 can be specifically adjusted, which is not specifically limited here. In one example, the washing appliance 100 is a dishwasher. In other embodiments, the washing appliance 100 can be a water-using appliance such as a washing machine. When the washing appliance 100 is a washing machine, the spray arm assembly 63 can be omitted. In addition, it can be understood that when the washing appliance 100 is a washing machine, the heat stored in the heat storage structure 55 can be used to heat the washing water, and can also be used to dry the clothes. .

[0046] See also Figure 8In some embodiments, the heat storage structure 55 includes a heat storage chamber (not shown), in which washing water is stored. The heat storage structure 55 can use the heat exchanged with the second heat exchange device 53 to heat the washing water stored in the heat storage chamber and can provide the washing appliance 100 with heated washing water.

[0047] Specifically, in this embodiment, the heat storage structure 55 can also be used as a water tank, and the water tank is formed with a heat storage cavity (not shown in the figure), and the heat storage medium is washing water. When the heat storage structure 55 is a water tank, the second heat exchange device 53 can use a shell-and-tube condenser, the inner tube of the shell-and-tube condenser is connected to the insulation water tank, the jacket tube is a refrigerant channel, and the pipeline 64 in the washing system 60 is connected to the insulation water tank. When the air-conditioning system 50 is working, the refrigerant flows through the jacket tube of the shell-and-tube condenser, condenses and releases heat in the jacket tube, and heats the washing water in the water tank. Since the pipeline 64 of the washing system 60 is connected to the insulation water tank, when hot water washing is required, the hot water in the insulation water tank can be directly transported to the spray arm assembly 63 through the pipeline 64. It can be understood that in other embodiments, the heat storage structure 55 can also be used in combination with a water tank and a phase change heat storage structure module, and the specific setting can be determined according to actual conditions.

[0048] It should be noted that, in the washing appliance 100 of the present embodiment, the air conditioning system 50 and the washing system 60 can be operated simultaneously, or the air conditioning system 50 or the washing system 60 can be operated. When the air conditioning system 50 and the washing system 60 are operated simultaneously and hot water washing is required, the heat storage structure 55 exchanges heat with the second heat exchange device 53 and the washing water at the same time. When the air conditioning system 50 is operated alone, the heat storage structure 55 only exchanges heat with the second heat exchange device 53. When the washing system 60 is operated alone, the heat storage structure 55 can exchange heat with the washing water, and the heat in the heat storage structure 55 comes from the heat stored in the previous operation of the air conditioning system 50. In some examples, the washing appliance 100 is also provided with an electric heating device. When the heat in the heat storage structure 55 is not enough to heat the washing water to the required temperature, the electric heating device can be turned on to perform auxiliary heating on the washing water.

[0049] In addition, in this embodiment, the washing system 60 and the air conditioning system 50 of the washing appliance 100 are integrally arranged in the cavity 10, and the washing system 60 is arranged above the air conditioning system 50. In this way, the user does not need to bend down when taking and placing the washing items, which improves the user experience. It can be understood that in some examples, the washing system 60 and the air conditioning system 50 can also be separately arranged, and the specific arrangement can be determined according to the actual situation.

[0050] In this embodiment, the refrigerant is a high-temperature and high-pressure steam working medium. The refrigerant in the refrigerant circuit is condensed in the second heat exchange device 53, and the high-temperature and high-pressure steam is condensed and releases heat to become a low-temperature and high-pressure liquid.

[0051] The throttling device 54 includes an expansion valve. The low-temperature and high-pressure liquid refrigerant formed after condensation by the second heat exchange device 53 becomes a low-temperature and low-pressure mist-like hydraulic refrigerant after throttling through the throttling hole of the expansion valve, creating conditions for the evaporation of the refrigerant. Of course, the throttling device 54 can also be other types, such as a capillary tube, etc., which are not specifically limited.

[0052] In summary, in the washing appliance 100 of the present embodiment, when the air conditioning system 50 is working, the cold air formed by the outside air exchanging heat with the first heat exchange device 51 can be exported to the outside atmosphere, and the heat storage structure 55 can store the heat of the airflow after heat exchange. In this way, the washing appliance 100 has a refrigeration capacity, which can meet the refrigeration needs of users during kitchen activities and improve user experience. The heat generated during the refrigeration process is stored by the heat storage structure 55, avoiding the waste of heat. In addition, when the washing system 60 of the washing appliance 100 is working, the heat stored in the heat storage structure 55 can heat the washing water, thus reducing the energy consumption during the use of the washing appliance 100 and saving energy.

[0053] Please combine Figure 3 and Figure 4 In some embodiments, the air duct system 30 includes an air outlet duct 32, which is disposed on the door body 20. The door body 20 is formed with an air outlet 322, which is connected to the air outlet duct 32. The air outlet duct 32 can guide the airflow after heat exchange with the first heat exchange device 51 out of the washing appliance 100.

[0054] In addition, in the above embodiment, when the door 20 opens the washing chamber 11, the air inlet end 321 of the air outlet pipe 32 is separated from the air outlet end 311 of the air duct 31 (such as Figure 4 When the door 20 closes the washing chamber 11, the air inlet end 321 of the air outlet pipe 32 is airtightly connected to the air outlet end 311 of the air duct 31 (as shown in FIG. Figure 3 shown).

[0055] Specifically, when the door 20 closes the washing chamber 11, the air inlet end 321 of the air outlet pipe 32 is airtightly connected to the air outlet end 311 of the air duct 31, and the cold air formed after heat exchange with the first heat exchange device 51 can flow through the air outlet pipe 32 and be discharged through the air outlet 322, thereby achieving a cooling effect. Since the air inlet end 321 of the air outlet pipe 32 is airtightly connected to the air outlet end 311 of the air duct, air leakage can be prevented, thereby improving the cooling effect of the washing appliance 100.

[0056] When the door 20 opens the washing chamber 11, the air inlet end 321 of the air outlet duct 32 is separated from the air outlet end 311 of the air duct 31, and the cold air formed after heat exchange with the first heat exchange device 51 can be directly discharged to the outside from the air outlet end 311 of the air duct 31, and the cooling effect can also be achieved. In this way, regardless of whether the door 20 of the washing appliance 100 opens the washing chamber 11, the washing appliance 100 can discharge the cold air to the outside atmosphere to achieve the cooling effect.

[0057] It is understandable that, in some embodiments, when the door body 20 opens the washing chamber 11, the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31 may also be in an airtight connection state, that is, the two are not separated. Specifically, the air outlet pipe 32 of this embodiment may be formed with a telescopic structure (not shown in the figure), and the air outlet pipe 32 is connected to the air outlet end 311 of the air duct 31 through the telescopic structure. When the door body 20 opens the washing chamber 11, the telescopic structure is extended, and when the door body 20 closes the washing chamber 11, the telescopic structure is shortened, thereby ensuring that the air outlet pipe 32 and the air outlet end 311 of the air duct 31 are always in a connected state. The telescopic structure can be a folding and contracting structure similar to an umbrella pole, which can be extended and shortened. The telescopic structure can also be a sleeve-type structure composed of two pipes, for example, composed of an outer pipe (not shown in the figure) and an inner pipe (not shown in the figure), and the inner pipe is arranged in the outer pipe and can be pulled out from the outer pipe or put into the outer pipe.

[0058] See also Figure 4 In some embodiments, the washing appliance 100 includes a seal 40, which is disposed at the air inlet end 321 of the air outlet pipe 32, and the seal 40 can seal the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31. When the door body 20 closes the washing chamber 11, the seal 40 seals the connection between the air outlet pipe 32 and the air outlet end 311 of the air duct 31, and when the door body 20 opens the washing chamber 11, the seal 40 is separated from the air outlet end 311 of the air duct 31.

[0059] In this way, it is possible to prevent air leakage from occurring when the air inlet end 321 of the air outlet pipe 32 is connected to the air outlet end 311 of the air duct 31, thereby preventing poor air exhaust inside the washing appliance 100.

[0060] Specifically, when the door 20 opens the washing chamber 11, the seal 40 follows the air outlet duct 32 away from the air outlet end 311 of the air duct 31, and the seal 40 is separated from the air outlet end 311 of the air duct 31. In this case, even if the air conditioning system 50 is in operation, the generated cold air can be discharged to the outside atmosphere through the air outlet end 311 of the air duct 31 without causing poor exhaust.

[0061] In this embodiment, the seal 40 can be a flexible member made of a flexible material such as rubber. When the door body 20 closes the washing chamber 11, the seal 40 is compressed at the air outlet end 311 of the air duct 31, thereby tightly connecting the air outlet pipe 32 and the air outlet end 311 of the air duct 31 to achieve an airtight connection between the two (such as Figure 3 When the door 20 opens the washing chamber 11, the sealing member 40 returns from the compressed state to the normal state and is disconnected from the air outlet 311 of the air duct 31 (eg, Figure 4 It should be noted that the above-mentioned normal state refers to the seal 40 returning to its normal length when it is not compressed. Figure 3 and Figure 5 In the example of , the seal 40 is in a compressed state. Figure 4 and Figure 6 In the example shown in FIG. 4 , the seal 40 is in a normal state.

[0062] It is understandable that, in other embodiments, the seal 40 may also be provided at the air outlet end 311 of the air duct 31. In this case, when the door body 20 closes the washing chamber 11, the seal 40 seals the connection between the air outlet pipe 32 and the air outlet end 311 of the air duct 31, and when the door body 20 opens the washing chamber 11, the seal 40 is separated from the air outlet pipe 32. That is to say, when the door body 20 opens the washing appliance 100, the seal 40 returns from the compressed state to the normal state, disconnects from the air outlet pipe 32 and moves away from the air outlet pipe 32. In addition, in some embodiments, a seal 40 may be provided at the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31, respectively, and when the door body 20 closes the washing chamber 11, the two seals 40 are pressed and contacted, thereby achieving an airtight connection. When the door body 20 opens the washing chamber 11, the two seals 40 are separated.

[0063] In addition, it can also be understood that in some embodiments, the material of the seal 40 is a flexible material that can be stretched and compressed. The seal 40 seals and connects the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31. In other words, the two ends of the seal 40 can be directly connected to the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31. Regardless of whether the door body 20 opens the washing chamber 11, the seal 40 and the air inlet end 321 of the air outlet pipe 32 and the air outlet end 311 of the air duct 31 are always in a sealed connection state. Specifically, when the door body 20 opens the washing chamber 11, the seal 40 is in a stretched state, and when the door body 20 closes the washing chamber 11, the seal 40 is in a compressed state.

[0064] It should be noted that, in the above embodiment, the connection method of the sealing member 40 to the air inlet end 321 of the air outlet pipe 32 and / or the air outlet end 311 of the air duct 31 can be at least one of the connection methods such as snap connection, nested connection and magnet adsorption connection.

[0065] For example, in Figure 4 In the embodiment, the seal 40 can be mounted on the air inlet end 321 of the air outlet duct 32 by a snap buckle or directly nested in the air inlet end 321 of the air outlet duct 32. In addition, the other end of the seal 40 can be set as a magnetic connection end, and a magnet can be set at the air outlet end 311 of the air duct 31. When the door body 20 closes the washing chamber 11, the seal 40 can be magnetically adsorbed on the air outlet end 311 of the air duct 31 to achieve the connection between the two. It can be understood that the specific connection method can also be other connection types, for example, one end of the seal 40 adopts magnetic connection, the other end adopts a nesting method, both ends adopt a nesting method, or both ends adopt a magnetic adsorption method, etc. The specific principle is basically similar to the principle described above, and will not be described in detail here.

[0066] In some embodiments, in order to effectively prevent the washing appliance 100 from having poor exhaust. When the washing appliance 100 is working, only when the door 20 closes the washing chamber 11, the first heat exchange device 51 performs heat exchange with the airflow of the air duct 31, and the cold air formed after the heat exchange is led to the washing appliance 100 through the air outlet pipe 32. That is to say, during the operation of the air conditioning system 50, when it is detected that the door 20 opens the washing chamber 11, the air conditioning system 50 is controlled to stop running, and when it is detected that the door 20 closes the washing chamber 11, the air conditioning system 50 is started and continues to run.

[0067] See also Figure 3 and Figure 4 In some embodiments, the air duct 31 is installed in the cavity 10 , and the air duct 31 is formed with an air inlet 312 on the cavity 10 , the air inlet 312 is located below the door body 20 , and the air outlet 322 is located above the door body 20 .

[0068] In this way, the air inlet 312 is set below the door body 20, and the air outlet 322 is located at the upper part of the door body 20. The air inlet 312 and the air outlet 322 are spaced apart by a large distance, which can effectively prevent the cold air discharged from the air outlet 322 from flowing back into the air inlet 312, so that the user can get a better cooling experience.

[0069] It is understandable that the air outlet 322 located at the upper part of the door body 20 may be located at the upper part of the front side of the door body 20, or located at the upper part of the side of the door body 20, or located at the top of the door body 20. In some examples, multiple air outlets 322 may be provided on the door body 20, for example, the air outlets 322 are provided at the upper part of the front side and the upper part of the side of the door body 20, or multiple air outlets 322 are provided at the front side of the door body 20. In addition, in some examples, the air inlet 312 may also be provided at the back or side of the washing appliance 100, and the air outlet 322 may also be provided at the back or side of the washing appliance 100.

[0070] In some embodiments, a rotating plate 70 is further provided at the air outlet 322 . There are multiple rotating plates 70 , and the rotating plates 70 are used to adjust the direction of the cold air discharged from the air outlet 322 .

[0071] In this way, the user can adjust the direction of the airflow by adjusting the rotation angle of the rotating plate 70, thereby obtaining a better experience.

[0072] Please read further Figure 3 and Figure 4 In some embodiments, the air conditioning system 50 includes a fan 56 , which is disposed in the air duct 31 . The fan 56 is used to accelerate the air flow speed in the air duct system 30 .

[0073] Specifically, the fan 56 can quickly introduce the outside air into the air duct 31 to exchange heat with the first heat exchange device 51, and can accelerate the air flow speed of the cold air after the heat exchange, thereby improving the cooling efficiency of the air-conditioning system 50.

[0074] It should be noted that the fan 56 can be arranged at any position in the air duct 31. Figure 3 and Figure 4 As shown, the fan 56 can be arranged at the downstream position of the airflow of the first heat exchange device 51, that is, the fan 56 is arranged between the first heat exchange device 51 and the air outlet 311 of the air duct 31. In other embodiments, the fan 56 can also be arranged at the upstream position of the airflow of the first heat exchange device 51, that is, the fan 56 is arranged between the first heat exchange device 51 and the air inlet 312 of the air duct 31.
