Referring to fig. 1 and 2, an air-conditioning type washing appliance 100 according to an embodiment of the present invention includes a washing system 10, an air-conditioning system 20, and a heat storage structure 30. The washing system 10 comprises a cavity 11 and a washing pump 12, wherein the washing pump 12 is connected with the cavity 11 through a pipeline.

The air conditioning system 20 includes an evaporator 21 (see fig. 1), a compressor 22 (see fig. 1), a first heat exchange device 23 (see fig. 1), a second heat exchange device 24 (see fig. 1), and a throttling device 25 (see fig. 1) connected to form a closed refrigerant loop, the evaporator 21 is configured to exchange heat with air through a refrigerant to make the air form cold air, the first heat exchange device 23 is configured to store heat released when the refrigerant condenses and heat the air exhausted from the cavity 11 with the heat, and the air exhausted from the cavity 11 is heated by the first heat exchange device 23 and then returns to the cavity. The heat storage structure 30 is capable of exchanging heat with the second heat exchange device 24, the second heat exchange device 24 is configured to exchange heat with the refrigerant and transfer heat to the heat storage structure 30, and the heat storage structure 30 is configured to store heat exchanged from the second heat exchange device 24 and heat the washing liquid for the washing system 10 with the heat.

In the air-conditioning washing appliance 100 according to the embodiment of the present invention, the first heat exchange device 23 can effectively store part of heat generated by the air-conditioning system 20 during the cooling process, and during the drying process, the first heat exchange device 23 can heat the air exhausted from the cavity 11 by using the stored heat, and the heated air further returns to the cavity 11 to dry the articles in the cavity 11, thereby improving the drying efficiency and improving the user experience. Meanwhile, the second heat exchanging device 24 can also transfer part of the heat generated by the air conditioning system in the refrigeration process to the heat storage structure 30, and the heat storage structure 30 can heat the washing liquid for the washing system 10 by using the heat exchanged with the second heat exchanging device 24, thereby reducing the energy consumption of the air-conditioning type washing appliance 100 in the washing process. In addition, the air-conditioning washing appliance 100 of the embodiment of the invention can be used for refrigerating independently, so that the refrigerating requirement of a user during kitchen activities can be met, and the user experience is improved.

It should be noted that the heat storage structure 30 is configured to store the heat exchanged from the second heat exchanging device 24 and heat the washing liquid used in the washing system 10 by using the heat, and may refer to that the heat storage structure 30 stores the heat first and heats the washing liquid when the washing liquid needs to be heated, or may directly store the heat in the washing liquid (that is, the heat storage medium of the heat storage structure 30 is the washing liquid, and the heat storage structure 30 stores the heat by using the washing liquid), and directly provide the heated washing liquid for the washing system 10 when the washing system 10 needs hot water.

Specifically, as shown in fig. 1 and fig. 2, in the present embodiment, the air-conditioning washing appliance 100 includes a drying air duct 27, the first heat exchanging device 23 is disposed in the drying air duct 27, the drying air duct 27 is communicated with the inside of the cavity 11, the drying air duct 27 is respectively formed with an air inlet 271 and an air outlet 272 at different positions of the cavity 11, and the air in the cavity 11 enters the drying air duct 27 through the air outlet 272, is heated by the first heat exchanging device 23, and then returns to the inside of the cavity 11 through the air inlet 271.

In addition, the washing system 10 further comprises a spray arm assembly 13, the inner spray arm assembly 13 is arranged in the cavity 11, the spray arm assembly 13 is used for spraying and washing the articles in the cavity 11, a water cup 111 is formed at the lower part of the cavity 11 and used for collecting the washing liquid in the cavity 11, the water cup 111 can be installed at the lower part of the cavity 11 after being formed separately from the cavity 11, or the water cup 111 can be directly formed integrally at the lower part of the cavity 11. The washing pump 12 is arranged outside the cavity 11, the washing pump 12 is connected with the water cup 111 and the spray arm assembly 13 through a pipeline, and the washing pump 12 can pump water in the water cup 111 to the spray arm assembly 13 to wash articles in the cavity 11.

When the air-conditioning washing appliance 100 is used for cooling, the air-conditioning system 20 is turned on, the refrigerant in the refrigerant loop is compressed into a high-temperature high-pressure gas refrigerant by the compressor 22, then the refrigerant is conveyed from the compressor 22 to the first heat exchange device 23 and the second heat exchange device 24, the high-temperature high-pressure gas refrigerant can be liquefied into a low-temperature high-pressure liquid refrigerant in the first heat exchange device 23 and the second heat exchange device 24 respectively and then enters the throttling device 25, the low-temperature high-pressure liquid refrigerant is changed into a low-temperature low-pressure gas-liquid two-phase state after passing through the throttling device 25 and then enters the evaporator 21 to be subjected to heat absorption to form a low-temperature low-pressure gas refrigerant, and then the low-temperature low-pressure gas refrigerant in the evaporator 21 enters.

Since the high-temperature and high-pressure gas refrigerant emits heat when passing through the first heat exchanging device 23 to be condensed, the first heat exchanging device 23 can store the heat. Similarly, the refrigerant also emits heat when flowing through the second heat exchange device 24 for condensation, and since the heat storage structure 30 is connected to the second heat exchange device 24 in a heat conducting manner, the heat emitted during condensation of the refrigerant can be transferred to and stored in the heat storage structure 30, and the heat storage structure 30 can heat the washing liquid for the washing system 10 by using the heat exchanged with the second heat exchange device 24, thereby achieving the purposes of storing the heat generated during the refrigeration process and heating the washing liquid by using the heat. It is understood that the heat absorbed by the refrigerant flowing through the evaporator 21 can be derived from air, and in this process, the air flowing through the evaporator 21 can be discharged out of the air-conditioning washing appliance 100 after heat exchange to form cold air, so as to achieve the effect of air-conditioning cooling.

When it is desired to use hot water for washing, the heat storage structure 30 may use the stored heat to heat the washing liquid, or directly provide the washing system 10 with the heated washing liquid (the heat storage medium in the heat storage structure 30 is water). The heated washing liquid enters the water cup 111, and the washing pump 12 continuously and circularly conveys the heated washing liquid in the water cup 111 to each spray arm of the spray arm assembly 13 through the pipeline, so that the purpose of washing articles is achieved. In the example of fig. 1 and 2, the spray arm assembly 13 has one spray arm. In other embodiments, the number of spray arms of the spray arm assembly 13 may be specifically adjusted, and is not specifically limited herein. In an example of the present invention, the air-conditioned washing appliance 100 is an air-conditioned dishwasher having a spray arm assembly 13. In other examples, the air-conditioning washing appliance 100 may be a water-using appliance such as an air-conditioning washing machine, and the air-conditioning washing machine may omit the spray arm assembly 13.

When the articles in the cavity 11 need to be dried after the washing is completed, the air in the cavity 11 can enter the drying air duct 27 from the air outlet 272, the heat stored in the first heat exchanging device 23 in the drying air duct 27 can heat the air in the drying air duct 27, and then the heated air returns to the cavity 11 through the air inlet 271 so as to improve the drying efficiency. In the example of fig. 1, the dashed arrows within the drying air duct 27 indicate the direction of flow of air within the drying air duct 27.

It should be noted that the above-mentioned washing liquid may be water or a mixture of water and a detergent, and the same and similar explanations or descriptions will be understood with reference to the explanations herein when appearing in the following embodiments. In the following embodiments, the washing liquid is used as water for example.

In the present embodiment, the refrigerant flowing through the evaporator 21 may absorb heat in air flowing through the evaporator 21 to form a low-temperature and low-pressure gas refrigerant, and the evaporator 21 may be a fin-tube evaporator or a microchannel evaporator, which is not particularly limited. The compressor 22 may be a horizontal compressor 22 or a vertical compressor 22, and the compressor 22 may be configured to compress a gas refrigerant evaporated by the evaporator 21 to obtain a high-temperature and high-pressure gas refrigerant.

The throttling device 25 may be an expansion valve, and a low-temperature and high-pressure liquid refrigerant condensed after heat exchange with the first heat exchanging device 23 and the second heat exchanging device 24 is throttled by a throttling hole of the expansion valve to become a low-temperature and low-pressure foggy hydraulic refrigerant, thereby creating conditions for evaporation of the refrigerant. Of course, the throttling device 25 may be of other types, such as capillary tube, etc., without limitation.

Referring again to fig. 1, in the above embodiment, the first heat exchange device 23 and the second heat exchange device 24 are connected in series between the compressor 22 and the throttling device 25.

Specifically, in the example of fig. 1, the first heat exchanger 23 and the second heat exchanger 24 are connected in series between the compressor 22 and the throttling device 25, and the refrigerant flows through the first heat exchanger 23 after flowing through the second heat exchanger 24. That is, the refrigerant exchanges heat with the second heat exchanger 24 and then exchanges heat with the first heat exchanger 23. In this way, the second heat exchanger 24 and the first heat exchanger 23 can absorb as much heat as possible, which is released when the refrigerant condenses.

It is understood that in some embodiments, the refrigerant may also flow through the first heat exchanging device 23 and then flow through the second heat exchanging device 24, which is not limited in particular.

Referring to fig. 2, in some embodiments, a first heat exchange device 23 and a second heat exchange device 24 are connected in parallel between the compressor 22 and the throttling device 25.

Specifically, in the example shown in fig. 2, the refrigerant is divided after flowing through the compressor 22, and flows through the first heat exchanger 23 and the second heat exchanger 24, respectively. In fig. 2, the refrigerant flows through the first heat exchanger 23 and the second heat exchanger 24, and the refrigerant can exchange heat with the first heat exchanger 23 and the second heat exchanger 24 simultaneously. At this time, both the first heat exchanging device 23 and the heat storage structure 30 are in the heat storage condition. That is, the heat released by the condensation of the refrigerant may be stored by the first heat exchanging device 23 to heat the air exhausted from the cavity 11 during the drying process, or transferred to the heat accumulating structure 30 through the second heat exchanging device 24 to heat the washing liquid for the washing system 11.

It is understood that, in other embodiments, when the first heat exchanging device 23 and the second heat exchanging device 24 are connected in parallel between the compressor 22 and the throttling device 25, valves (not shown) may be provided in the refrigerant path between the first heat exchanging device 23 and the compressor 22 and the refrigerant path between the second heat exchanging device 24 and the compressor 22. The user can control the opening and closing of the valve to control the refrigerant to flow through only the first heat exchanging device 23 or only the second heat exchanging device 24.

When the refrigerant flows only through the first heat exchanger 23, the refrigerant is condensed only in the first heat exchanger 23. At this time, the first heat exchange device 23 is in the heat storage working condition, and the heat storage structure 30 is not in the heat storage working condition. The first heat exchanging means 23 stores heat during the drying process, and the heat in the first heat exchanging means 23 can be used to heat the air exhausted from the chamber 11. That is, when the refrigerant flows through only the first heat exchanging device 23, the heat released by the condensation of the refrigerant is only stored by the first heat exchanging device 23 and is only used for heating the air exhausted from the cavity 11 during the drying process.

When the refrigerant flows through only the second heat exchanging device 24, the refrigerant is condensed only in the second heat exchanging device 24, and the second heat exchanging device 24 transfers heat emitted when the refrigerant is condensed to the heat accumulating structure 30 to heat the washing liquid for the washing system 11. At this time, the first heat exchange device 23 is not in the heat storage condition. That is, when the refrigerant flows only through the second heat exchanging device 24, the heat released by the refrigerant condensation is only stored in the heat storage structure 30 and is only used for heating the washing liquid.

To sum up, when the first heat exchanging device 23 and the second heat exchanging device 24 are connected in parallel between the compressor 22 and the throttling device 25, the washing appliance 100 can have various working conditions for users to select, so that the use scenes of the washing appliance 100 are enriched, and the use experience of the users is improved. Meanwhile, even if one of the first heat exchanging means 23 and the second heat accumulating structure 30 is damaged, the washing appliance 100 loses only one function of heating the washing liquid or heating the air exhausted from the cavity 11.

In the example of fig. 1 and 2, the arrows on the refrigerant circuit indicate the direction in which the refrigerant flows in the refrigerant circuit.

Referring to fig. 3, in some embodiments, the first heat exchanging device 23 includes a box 231, a refrigerant flowing pipeline 232, an air heat exchanging channel 233 and a phase change heat storing material 234, the refrigerant flowing pipeline 232 penetrates through the box 231, the air heat exchanging channel 233 also penetrates through the box 231 and is isolated from the refrigerant flowing pipeline 232, the phase change heat storing material 234 is disposed in the box 231 and contacts the refrigerant flowing pipeline 232 and the air heat exchanging channel 233, the air heat exchanging channel 233 is communicated with the drying air duct 27, and air in the drying air duct 27 can flow through the air heat exchanging channel 233 to be heated by the first heat exchanging device 23.

Specifically, the refrigerant circulation line 232 is a part of the refrigerant circuit and is used for conveying the refrigerant. When the air conditioning system 20 performs cooling, the refrigerant is condensed and released while flowing through the refrigerant flow line 232, and the phase change heat storage material 234 in the case 231 can store the released heat. In the drying process, the air in the cavity 11 enters the drying air duct 27 and then flows through the air heat exchange flow channel 233, and the heat stored in the phase change heat storage material 234 can directly heat the air flowing through the air heat exchange flow channel 233.

In the present embodiment, the phase change heat storage material 234 is in direct contact with the refrigerant flow line 232 and the air heat exchange flow channel 233 to achieve heat exchange. It is understood that in other embodiments, the phase change heat storage material 234 may be in indirect contact with the refrigerant circulation pipeline 232 and the air heat exchange flow channel 233 through other heat transfer media, where the other media are media with better heat transfer effect, such as heat conductive silica gel, metal, and the like.

It is understood that, in the present embodiment, the phase change heat storage material 234 may be a solid-liquid phase change heat storage material or a solid-solid phase change heat storage material, and the phase change temperature thereof is generally set to 40 to 55 degrees, and the specific material and the phase change temperature may be selected according to the actual situation.

Referring further to fig. 1 and 2, in some embodiments, the air-conditioning washing appliance 100 further includes a first fan 28 and a switching device (not shown), the first fan 28 and the switching device are disposed in the drying air duct 27, the first fan 28 is used for accelerating the air flow speed in the drying air duct 27, and the switching device is used for opening and closing the drying air duct 27.

Specifically, in order to prevent the heat in the cavity 11 from being dissipated too much to reduce the washing effect during the washing process of the air-conditioning washing appliance 100, the first fan 28 is in a closed state, and the switching device also closes the drying air duct 27. When the air enters the drying process after the washing is finished, the switching device conducts the drying air duct 27, the air in the cavity 11 enters the drying air duct 27, is heated when flowing through the first heat exchanging device 23, and then returns to the cavity 11 again to improve the drying effect. In the process, the first fan 28 can be turned on to accelerate the air flow rate in the drying air duct 27, shorten the drying time and improve the drying efficiency.

It should be noted that the first fan 28 is a fan described in the claims. The first fan 28 may be a cross-flow fan or an axial-flow fan, and the like, and is not particularly limited. The switching device can adopt an air valve, a grid, a shutter and the like, is not limited specifically, and only needs to realize the function of opening and closing the drying air duct. Furthermore, the above-mentioned "the first fan 28 and the switching device are both disposed in the drying air duct 27" means that the first fan 28 and the switching device may be disposed inside the drying air duct 27 or at the air inlet 271 or the air outlet 272 of the drying air duct 27.

In some embodiments, the heat accumulating structure 30 includes a housing and a heat accumulating portion (not shown) located in the housing, the second heat exchanging device 24 is disposed in the housing and in heat-conductive contact with the heat accumulating portion, and the air-conditioned washing appliance 100 includes a first liquid inlet pipe (not shown) for connecting an external water source and the cavity 11, the first liquid inlet pipe is disposed through the housing and in heat-conductive contact with the heat accumulating portion.

Specifically, the heat storage portion is used for storing heat, the second heat exchange device 24 may be a condensation pipe, the second heat exchange device 24 is in heat conduction contact with the heat storage portion, that is, the second heat exchange device 24 can perform heat transfer with the heat storage portion in a desired manner, and the first liquid inlet pipe is in heat conduction contact with the heat storage portion, that is, the heat storage portion can perform heat transfer with the washing liquid in the first liquid inlet pipe in a desired manner.

Further, in the present embodiment, the heat storage medium of the heat storage portion may be a phase change heat storage material, such as a solid-liquid phase change heat storage material or a solid-solid phase change heat storage material. The phase-change heat storage material is connected with the second heat exchange device 24 and the first liquid inlet pipe in a heat conduction mode, the phase-change heat storage material can store heat emitted when a refrigerant is condensed in the second heat exchange device 24, and when the washing electric appliance needs to be washed by hot water, the phase-change heat storage material can release heat to heat washing liquid in the first liquid inlet pipe.

It is understood that the present embodiment can make the size of the heat storage structure 30 smaller than that of the washing appliance 100 smaller and more compact than that of the other heat storage materials, such as water, as the heat storage medium. In addition, when the phase change heat storage material is used as the heat storage medium, the heat storage structure 30 has a higher heat storage capacity.

With continued reference to fig. 1 and 2, in some embodiments, the heat storage structure 30 includes a housing 31, a heat storage chamber 32 is formed in the housing 31 for storing the washing liquid, the chamber 11 of the washing system 10 is connected to the heat storage chamber 32 by a pipeline, and the second heat exchanging device 24 is connected to the heat storage chamber 32 by a pipeline to form a circulation loop 33 of the washing liquid.

Thus, when the washing system 10 needs hot water washing, the heated washing liquid in the heat storage chamber 32 can flow into the water cup 111 through the pipeline, and then be conveyed to the spray arm assembly 13 by the washing pump 12, so as to perform hot water washing on the articles placed in the cavity 11.

Specifically, in this embodiment, the second heat exchanging device 24 may adopt a sleeve-type condenser, which includes a heat exchanging pipe (not shown) and a refrigerant conveying pipe (not shown), the heat exchanging pipe is used for conveying a washing liquid, a circulation liquid inlet (not shown) and a circulation liquid outlet (not shown) are formed on the heat storage cavity 32, the heat exchanging pipe of the second heat exchanging device 24 is connected to the circulation liquid inlet and the circulation liquid outlet, the washing liquid in the heat storage cavity 32 may flow into the heat exchanging pipe of the first heat exchanging device 23 through the circulation liquid outlet, and then is heated in the heat exchanging pipe, and the heated washing liquid flows into the heat storage cavity 32 through the circulation liquid inlet, so as to form a circulation loop 33 of the washing liquid. The refrigerant conveying pipe is used for conveying refrigerants, the refrigerant conveying pipe is sleeved with the heat exchange pipe, the heat exchange pipe is in heat conduction connection with the refrigerant conveying pipe, the refrigerants are condensed and release heat when flowing through the refrigerant conveying pipe, heat is transferred to the heat exchange pipe to heat washing liquid in the heat exchange pipe, and the heated washing liquid flows into the heat storage cavity 32 through the circulating loop 33. In addition, a liquid inlet (not shown) and a liquid outlet (not shown) are formed on the heat storage cavity 32, the liquid inlet is used for replenishing the heat storage cavity 32 with the washing liquid, the liquid outlet is connected with the cavity 11 through a pipeline, and the water heated in the heat storage cavity 32 can flow into the cavity 11 through the liquid outlet. It is understood that, in other embodiments, the second heat exchanging device 24 may also adopt a heat exchanger such as a plate condenser, and is not limited in particular.

In addition, in some embodiments, the second heat exchange device 24 may also adopt a phase change heat storage structure, and specifically, the second heat exchange device 24 may include a phase change heat storage material, a refrigerant may flow through the second heat exchange device 24, a washing liquid in the heat storage cavity 32 may also flow through the second heat exchange device 24, and the phase change heat storage material may exchange heat with the condensed washing liquid and the washing liquid. When the refrigerant is condensed, the released heat is absorbed by the phase change heat storage material, and when the washing liquid flows through the second heat exchange device 24, the phase change heat storage material releases heat to heat the washing liquid flowing through the second heat exchange device 24.

In the present embodiment, the casing 31 of the thermal storage structure 30 may be made of a thermal insulating material, or the outer surface of the casing 31 may be coated with a thermal insulating material. In this way, excessive heat dissipation in the heat storage chamber 32 can be prevented.

Referring to fig. 1 and 2 again, in some embodiments, the air-conditioning washing appliance 100 further includes a second liquid inlet pipe 37, the second liquid inlet pipe 37 is connected to the housing 31, and the second liquid inlet pipe 37 is communicated with the heat storage chamber 32.

Specifically, the second liquid inlet pipe 37 is connected to a liquid inlet on the heat storage chamber 32, and the second liquid inlet pipe 37 replenishes the washing liquid for the heat storage chamber 32 through the liquid inlet. In addition, the second liquid inlet pipe 37 is provided with a liquid inlet switch 40, when the air conditioning system 20 operates, the liquid inlet switch 40 is turned on, the washing liquid enters the heat storage cavity 32 through the second liquid inlet pipe 37, and when water enters for a period of time or the liquid level of the heat storage cavity 32 reaches a certain height, the liquid inlet switch 40 is turned off, and the liquid inlet is stopped. It will be appreciated that if it is detected that the cleaning solution in the heat storage chamber 32 is insufficient to meet the requirements for circulation in the circulation loop 33 before the air conditioning system 20 is operated, a certain amount of cleaning solution is required before the air conditioning system 20 is turned on.

Referring to fig. 4, in some embodiments, a first cut-off valve 26 is disposed in a pipeline between the second heat exchanging device 24 and the heat accumulating chamber 32, and the first cut-off valve 26 is used for opening the circulation loop 33 when the air conditioning system 20 is in operation and cutting off the circulation loop 33 when the air conditioning system 20 is closed.

Thus, when the air conditioning system 20 is turned off, the refrigerant stops flowing, the heat exchange process of the refrigerant also stops, and the circulation loop 33 at the stage of the first stop valve 26 can prevent the heated washing liquid in the heat storage cavity 32 from circulating in the circulation loop 33 to cause heat loss.

Referring to fig. 5, in some embodiments, the air-conditioning washing appliance 100 further includes a circulation pump 35, the circulation pump 35 is disposed in the pipeline between the heat exchange pipe and the heat storage chamber 32, the circulation pump 35 is turned on when the air-conditioning system 20 is in operation, and the circulation pump 35 is turned off when the air-conditioning system 20 is turned off.

Thus, when the air conditioning system 20 operates, the circulation pump 35 is turned on, so that the circulation speed of the washing liquid in the heat storage cavity 32 in the circulation loop 33 can be increased, the washing liquid in the heat storage cavity 32 can absorb the heat emitted during the condensation of the refrigerant more quickly, and the performance of the air conditioning system 20 is ensured. When the air conditioning system 20 is turned off, the second heat exchange device 24 stops exchanging heat with the heat storage structure 30, and the circulation pump 35 is turned off.

Note that, in the examples shown in fig. 4 and 5, the arrows on the circulation circuit 33 indicate the circulating flow direction of the washing liquid in the circulation circuit 33. It will be appreciated that the flow direction is merely exemplary and that the flow direction of the scrubbing liquid in the recirculation loop 33 may be reversed from that shown.

Referring again to fig. 4 and 5, in some embodiments, a liquid inlet pump 36 is disposed in the pipeline between the cavity 11 and the heat storage cavity 32, and the liquid inlet pump 36 can deliver the washing liquid in the heat storage cavity 32 to the cavity 11.

In this way, the liquid inlet speed from the heat accumulation cavity 32 into the cavity 11 of the washing system 10 can be increased.

It is understood that the air-conditioning washing appliance 100 may be provided without the liquid inlet pump 36, and the second liquid inlet pipe 37 is directly used to replenish the heat accumulation chamber 32 so as to make the washing liquid in the heat accumulation chamber 32 flow into the chamber 11 of the washing system 10.

Furthermore, it will be appreciated that in some embodiments, the liquid inlet pump 36 may also be capable of delivering the scrubbing liquid in the chamber 11 to the thermal storage chamber 32 for storage.

Specifically, when the washing appliance 100 needs to be drained, for example, when the washing sequence of the washing appliance 100 is finished and the washing liquid in the heat storage chamber 32 is substantially consumed, the liquid inlet pump 36 may re-pump the filtered washing liquid in the cavity 11 into the heat storage chamber 32 for storage and recycling. In this way, the heat storage chamber 32 can provide hot water for the washing appliance 100 and can also recover and store the discharged water, and the washing appliance 100 does not need to be provided with a separate water storage device to recover and store the discharged water, thereby reducing the volume of the washing appliance 100 and reducing the manufacturing cost.

With continued reference to fig. 4 and 5, in some embodiments, the air-conditioning washing appliance 100 further includes a second cut-off valve 34, the second cut-off valve 34 is disposed in the pipeline between the cavity 11 and the heat accumulating chamber 32, the second cut-off valve 34 is used for conducting the pipeline between the cavity 11 and the heat accumulating chamber 32 when the washing system 10 is in operation, and for cutting off the pipeline between the cavity 11 and the heat accumulating chamber 32 when the washing system 10 is closed.

In this way, when the washing system 10 is closed, no water is needed for washing, and the second stop valve 34 cuts off the pipeline between the cavity 11 and the heat storage cavity 32, so that the washing liquid in the heat storage cavity 32 can be prevented from entering the cavity 11.

It should be noted that the second stop valve 34 described above represents a stop valve described in claims.

In some embodiments, the air-conditioned washing appliance 100 is formed with a temperature detection port (not shown) disposed on the heat storage chamber 32 of the heat storage structure 30 for mounting a temperature detection device to detect the temperature of the washing liquid.

In this manner, the temperature sensing device may monitor the temperature of the cleaning solution in real time as the solution is fed through the thermal storage chamber 32 to the washing system 10. When the temperature of the washing liquid is lower, the pipeline between the cavity 11 and the heat storage cavity 32 can be cut off by closing the second stop valve 34, so that the washing effect is prevented from being influenced by the fact that the temperature of the washing liquid entering the cavity 11 is too low.

It is understood that in other embodiments, the temperature detection port may be disposed on the pipe between the heat exchange pipe and the heat accumulation chamber 32, that is, on the circulation loop 33.

It should be noted that, in the embodiment of the present invention, the air conditioning system 20 and the washing system 10 may be operated simultaneously, or only the air conditioning system 20 or only the washing system 10 may be operated. It can be understood that, when the air conditioning system 20 and the washing system 10 are simultaneously operated and hot water washing is required, the first heat exchanging device 23 stores heat released by condensation of the refrigerant, and the heat accumulating structure 30 heats the washing water by using the heat transferred by the second heat exchanging device 24 and also directly provides the heated washing water to the washing system 10.

When the air conditioning system 20 operates alone, the first heat exchange device 23 stores heat released when the refrigerant is condensed, and the heat storage structure 30 heats the washing liquid in the heat storage cavity 32 by using the heat transferred by the second heat exchange device 24. In a stand-alone operation of the washing system 10, the heat accumulating structure 30 may directly provide the washing system 10 with washing liquid that has been heated.

In some examples, the air-conditioned washing appliance 100 may further be provided with an electric heating pipe, which may be integrated in the washing pump 12, and may be turned on to assist in heating the washing liquid entering the washing system 10 when the heat in the first heat exchanging device 23 is not sufficient to heat the first washing liquid to the desired temperature or the temperature of the washing liquid in the heat accumulating structure 30 does not reach the desired temperature.

In addition, referring to fig. 6, in some embodiments, an electric heating device 70 is disposed in the drying air duct 27, the electric heating device 70 is disposed near the air inlet 271, and the electric heating device 70 can further heat the air heated by the first heat exchanging device 23 in the drying air duct 27, so as to further improve the drying effect.

Referring to fig. 1 to 6, in some embodiments, the air-conditioning washing appliance 100 further includes an air duct system 60, the evaporator 21 is disposed in the air duct system 60, and the air duct system 60 is configured to introduce the external air to exchange heat with the refrigerant at the evaporator 21 and introduce the cold air formed after the heat exchange into the external environment to achieve the cooling effect. In the illustrated example, the dashed arrows within the duct system 60 indicate the air flow direction.

Referring to fig. 1 to 6, the air-conditioning washing appliance 100 of the above embodiment further includes a second fan 61, the second fan 61 is disposed in the air duct system 60, and the second fan 61 is used for accelerating the air flow speed in the air duct system 60.

Specifically, the fan 60 can rapidly guide the external air into the duct system 60, and accelerate the air flow velocity of the cold air after heat exchange, thereby improving the refrigeration efficiency of the air conditioning system 20. The type of the second fan 61 may or may not be identical to the type of the first fan 28.

It is understood that in the above embodiment, during the season when the air conditioning system 20 is not operated for a long time, the liquid may be directly supplied through the external liquid supply line 50, and may be heated by the electric heating pipe when hot water washing is required. The valve 51 is arranged on the external liquid inlet pipeline, when the external liquid inlet pipeline 50 needs to be adopted for liquid inlet, the valve 51 conducts the external liquid inlet pipeline 50, and when the external liquid inlet pipeline 50 does not need to be adopted for liquid inlet, the valve 51 closes the external liquid inlet pipeline.

The air-conditioning washing appliance 100 of the above embodiment further includes a drain pump (not shown) connected to the chamber 11, and after the washing sequence is completed, the drain pump is turned on to discharge the washing residual water.

The washing system 10 of the air-conditioning type washing appliance 100 according to the embodiment of the present invention mainly includes a pre-washing stage, a main-washing stage, a rinsing stage, and a drying stage when operating. The various stages will be briefly described and explained below by taking as an example that the heat storage medium of the heat storage structure 30 is water (i.e., the heat storage chamber 32 of the heat storage structure 30 is used to store the washing liquid).

The prewashing stage comprises water drainage, water inlet and circulating water spray, and is mainly characterized in that the water is drained by a drainage pump, the residual water washed last time is drained, then a liquid inlet switch 40 on a second liquid inlet pipe 37 and a second stop valve 34 are opened, hot water in a heat storage cavity 32 flows into the cavity 11, the water inlet amount can be detected through a flow detection device, the water inlet is stopped when the water inlet amount is enough, then the washing pump 12 is started to convey the hot water to the spray arm assembly 13, the spray arm assembly 13 sprays water outwards, and articles in the cavity 11 are washed circularly to achieve the purpose of prewashing.

The main washing stage comprises water drainage, water inlet, circulating water spraying, washing liquid heating and water drainage, the water inlet and the circulating water spraying are similar to those of the pre-washing stage, after the circulating water spraying is carried out for a period of time, the washing liquid needs to be heated, part of water can be drained firstly in the process, then part of hot water can be fed again from the heat storage cavity 32 of the heat storage structure 30, the water can also be directly heated through the electric heating pipe, and the water heating process can be specifically determined according to actual conditions. In addition, detergent is added at a specific time of the main washing stage to wash the articles clean.

The rinse phase is substantially similar to the main wash phase, in which detergent or dishwashing agent (for dishes) may also be added. And in the drying stage, the switching device opens the drying air duct 27, and the air in the cavity returns to the cavity after being processed by the first heat exchange device in the drying air duct 27, and the process is circulated in such a way so as to achieve the purpose of drying. After drying for a certain time, the washing sequence is finished, the air-conditioning washing appliance 100 is turned off, the hot water in the heat storage chamber 32 is basically consumed by the operation of the washing system 10, and finally, the conventional cold water is stored. It will be appreciated that after the washing cycle is completed, the washing liquid in the washing system may not be discharged to the outside, but may be pumped directly into the heat storage chamber 32 by the liquid inlet pump 36 for storage, so as to be recycled, for example, for use in a pre-washing stage of the next washing.
