Referring to fig. 1 to 5, an air-conditioning 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, a washing pump 12 and a spray arm assembly 13, wherein the washing pump 12 is respectively connected with the cavity 11 and the spray arm assembly 13 through a pipeline 14.
The air conditioning system 20 includes a first heat exchange device 21, a compressor 22, a second heat exchange device 23, and a throttle device 24 connected to form a closed refrigerant circuit, the first heat exchange device 21 is configured to exchange heat with air by a refrigerant to form cold air, the refrigerant heat-exchanged with air is compressed by the compressor 22 and then flows through the second heat exchange device 23, and the second heat exchange device 23 is configured to exchange heat with the refrigerant compressed by the compressor 22. The heat storage structure 30 is capable of exchanging heat with the second heat exchange device 23, the heat storage structure 30 being configured to store heat exchanged from the second heat exchange device 23 and to heat a wash liquid for the washing system 10 with the heat.
Specifically, the heat storage structure 30 is configured to store heat exchanged from the second heat exchange device 23 and heat the washing liquid used in the washing system 10 by using the heat, which may mean that the heat storage structure 30 stores the heat first, heats the washing liquid when the washing liquid needs to be heated, or directly stores the heat in the washing liquid (i.e., the heat storage medium of the heat storage structure 30 is the washing liquid, and the heat storage structure 30 stores the heat by the washing liquid), and directly provides the heated washing liquid to the washing system 10 when the washing system 10 needs hot water. It will be appreciated that the wash liquor may be water or a mixture of water and detergent.
When the air conditioning type washing electric appliance 100 is used for refrigerating, the air conditioning system 20 is started, cold coal in a refrigerant loop is compressed into high-temperature high-pressure gas by the compressor 22, then the refrigerant is conveyed to the second heat exchange device 23 from the compressor 22, the high-temperature high-pressure gas is liquefied into low-temperature high-pressure liquid in the second heat exchange device 23, the low-temperature high-pressure liquid becomes gas-liquid two phases in a low-temperature low-pressure state after passing through the throttling device 24, then the gas enters the first heat exchange device 21 to absorb heat to form low-temperature low-pressure gas, and then the low-temperature low-pressure gas in the first heat exchange device 21 enters the compressor 22 to be compressed again to enter the next cycle. Because the heat storage structure 30 is connected with the second heat exchange device 23 in a heat conduction manner, the high-temperature and high-pressure gas refrigerant emits heat when being liquefied in the second heat exchange device 23, the emitted heat is transferred to the second heat exchange device 23, the second heat exchange device 23 exchanges heat with the heat storage structure 30, and the heat is stored by the heat storage structure 30. It can be understood that the heat absorbed by the refrigerant flowing through the first heat exchange device 21 can be derived from air, and in this process, the air flowing through the first heat exchange device 21 forms cold air after heat exchange, and then is discharged out of the air-conditioning washing appliance 100, so as to achieve the air-conditioning refrigeration effect.
Referring to fig. 1 and 3, in the present embodiment, a water cup 111 is formed at a lower portion of the cavity 11 for collecting the washing liquid in the cavity 11, a spray arm assembly 13 is disposed in the cavity 11, a washing pump 12 is disposed outside the cavity 11, and the washing pump 12 is connected to the water cup 111 and the spray arm assembly 13 through a pipeline 14. When the air-conditioning type washing electric appliance 100 is used for washing, the washing system 10 is started, and the washing pump 12 continuously circularly conveys the washing liquid in the water cup 111 to each spray arm of the spray arm assembly 13 through the pipeline 14, so that the aim of washing articles is fulfilled. When it is desired to use hot water for washing, the heat stored by the thermal storage structure 30 may heat the washing liquid flowing through the thermal storage structure 30 or may directly provide the washing system 10 with the heated washing liquid (i.e., the thermal storage medium of the thermal storage structure 30 is the washing liquid, and the thermal storage structure 30 stores the heat through the washing liquid). In the examples shown in fig. 1, 3 and 5 and 6, 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-conditioning washing appliance 100 is an air-conditioning dishwasher 100 having a spray arm assembly 13. In other examples, the air-conditioning washing appliance 100 may be an appliance for water use such as an air-conditioning washing machine, and the air-conditioning washing machine may omit the spray arm assembly.
In this embodiment, the compressor 22 may be a horizontal compressor or a vertical compressor, the first heat exchange device 21 may be an evaporator, the evaporator may be a tube fin evaporator or a micro-channel evaporator, and the second heat exchange device 23 may be a condenser or a condenser tube, which is not limited specifically and may be determined according to practical situations.
The throttling device 24 comprises an expansion valve, and the low-temperature high-pressure liquid refrigerant formed by condensation of the second heat exchange device 23 is throttled by an orifice of the expansion valve to become a low-temperature low-pressure vaporous hydraulic refrigerant, so that conditions are created for evaporation of the refrigerant. Of course, the throttle device 24 may be of other types, such as a capillary tube, etc., without limitation.
As described above, in the air-conditioning washing appliance 100 according to the embodiment of the present invention, when the air-conditioning system 20 is in operation to perform cooling, the refrigerant exchanges heat with the first heat exchange device 21 and then enters the compressor 22, the refrigerant is compressed by the compressor 22 to form a high-temperature refrigerant, the high-temperature refrigerant exchanges heat with the second heat exchange device 23, so that heat is transferred to the second heat exchange device 23, and the heat of the second heat exchange device 23 can be stored by the heat storage structure 30 and used for heating the washing liquid for the washing system 10. In this way, the air-conditioning type washing electric appliance 100 can effectively utilize the heat generated by the air-conditioning system 20 in the refrigerating process to heat the washing liquid, so that the energy consumption of the air-conditioning type washing electric appliance 100 in the washing process is reduced. Meanwhile, the air-conditioning washing appliance 100 has a refrigerating function, can meet the refrigerating requirement of a user during kitchen activities, and improves user experience.
In the examples of fig. 3, 5, and 6, 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 heat storage structure 30 includes a case 31 and a heat storage portion 32, the heat storage portion 32 is located in the case 31, the second heat exchange device 23 may be disposed in the case 31 and in thermal conductive contact with the heat storage portion 32, the air conditioner washing appliance 100 includes a first water inlet pipe 40, the first water inlet pipe 40 is used for connecting an external water source and the cavity 11, and the first water inlet pipe 40 penetrates through the case 31 and is in thermal conductive contact with the heat storage portion 32.
Specifically, the heat storage portion 32 is used to store heat, the second heat exchange device 23 may employ a condensation tube, the heat-conducting contact between the second heat exchange device 23 and the heat storage portion 32 means that the second heat exchange device 23 can perform heat transfer with the heat storage portion 32 in a desired manner, and the heat-conducting contact between the first water inlet pipe 40 and the heat storage portion 32 means that the heat storage portion 32 can perform heat transfer with the washing liquid in the first water inlet pipe 40 in a desired manner.
In addition, in the present embodiment, the heat storage medium of the heat storage portion 32 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 temperature point of which is generally 40 to 55 degrees. The phase-change heat storage material is connected with the second heat exchange device 23 and the first water inlet pipe 40 in a heat conduction manner, and can store heat released by the refrigerant when the refrigerant condenses in the second heat exchange device 23, and can release heat to heat the washing liquid in the first water inlet pipe 40 when the washing electric appliance 100 needs hot water washing.
It will be appreciated that the use of the phase change thermal storage material as the thermal storage medium in this embodiment enables the thermal storage structure 30 to be made smaller in size, thereby enabling the washing appliance 100 to be smaller in size and more compact in structure, than when other thermal storage materials are used as the thermal storage medium, such as water. In addition, when the phase-change heat storage material is used as the heat storage medium, the heat storage capacity of the heat storage structure 30 is stronger.
Referring to fig. 4, in the present embodiment, the second heat exchange device 23 and the heat storage structure 30 may be combined to form a heat storage condenser for condensation and heat storage.
Specifically, a refrigerant circulation pipe (corresponding to the second heat exchange device 23 being a condensation pipe) and a water intake channel (corresponding to the first water intake pipe 40 penetrating the case 31) are formed in the heat storage condenser, both of which are coiled in the case 31 and are thermally connected with the phase change heat storage material of the heat storage portion 32, the refrigerant circulation pipe is formed with a refrigerant inlet 311 and a refrigerant outlet 312 on the case 31, and the water intake channel is formed with a water channel water inlet 313 and a water channel water outlet 314 on the case 31.
When the air conditioning system 20 is operated to perform cooling, the refrigerant enters the refrigerant circulation line through the refrigerant inlet 311, heat generated during condensation is absorbed by the heat storage portion 32, the heat is stored, and the condensed refrigerant flows out from the refrigerant outlet 312. When the washing system 10 works and needs to heat the washing liquid, the washing liquid is fed through the first water inlet pipe 40, flows in through the water channel water inlet 313, the heat stored in the heat storage part 32 in the heat storage structure 30 heats the washing liquid in the water channel, and the heated hot water flows out from the water channel water outlet 314 to reach the inside of the cavity 11, so that the purpose of heating the washing liquid is achieved. It will be appreciated that when heating of the wash liquor is not required, it is possible to feed water directly into the water cup 111 through the external water inlet line 60 instead of through the first water inlet line 40, and then deliver cold water directly to the spray arm assembly 13 through the wash pump 12.
Referring again to fig. 3, in the present embodiment, in order to increase the water intake speed, a water intake pump 28 is mounted on the first water intake pipe 40. When hot water washing is required, the water inlet pump 28 is turned on to pump the washing liquid flowing through the heat storage structure 30 and heated by the heat storage structure 30 into the cavity 11.
In the present embodiment, the first water inlet pipe 40 is further provided with a valve 41, and when hot water washing is not required, the valve 41 is closed to stop water from the outside water source into the tank 31. At this time, the external water inlet line 60 may be used to directly feed water.
Referring to fig. 5 and 6, in some embodiments, the heat storage structure 30 includes a housing 33, and a heat storage chamber 34 for storing a washing liquid is formed in the housing 33, and the chamber 11 of the washing system 10 is connected to the heat storage chamber 34 through a pipeline. The second heat exchange device 23 includes a heat exchange tube (not shown) and a refrigerant conveying tube (not shown), the refrigerant conveying tube is used for conveying a refrigerant, the heat exchange tube is connected with the refrigerant conveying tube in a heat conducting manner, and a heat exchange tube pipeline is connected with a heat storage cavity 34 of the heat storage structure 30 to form a circulation loop 25 of the washing liquid.
In this way, the heat storage structure 30 can directly store the heat released when the refrigerant condenses in the second heat exchange device 23 in the washing liquid in the heat storage chamber 34 (i.e. heat the washing liquid) when the air conditioning system 20 is in operation, and the temperature of the washing liquid increases after absorbing the heat. When the washing system 10 needs hot water washing, the heated washing liquid in the heat storage cavity 34 can directly flow into the cavity 11, and then is conveyed to the spray arm assembly 13 by the washing pump 12 to wash articles with hot water.
Specifically, referring to fig. 5-7, in the embodiment, the heat storage medium of the heat storage structure 30 is water, the heat storage cavity 34 is formed with a circulation water inlet 341 and a circulation water outlet 342, the heat exchange tube of the second heat exchange device 23 is connected with the circulation water inlet 341 and the circulation water outlet 342, the water in the heat storage cavity 34 can flow into the heat exchange tube of the second heat exchange device 23 through the circulation water outlet 342, and then is heated in the heat exchange tube, and the heated water flows into the heat storage cavity 34 through the circulation water inlet 341, so as to form the circulation loop 25 of the washing liquid. In addition, a water inlet 343 and a water outlet 344 are formed on the heat storage chamber 34, the water inlet 343 is used for supplementing water for the heat storage chamber 34, the water outlet 344 is connected with the chamber 11 in a pipeline, and the heated water in the heat storage chamber 34 can flow into the chamber 11 through the water outlet 344.
The high-temperature and high-pressure refrigerant compressed by the compressor 22 is condensed when flowing through the refrigerant flowing pipeline of the second heat exchange device 23, the washing liquid in the heat storage cavity 34 can flow in the heat exchange pipe through the circulation loop 25, and heat released during condensation is transferred to the washing liquid in the heat exchange pipe (namely the washing liquid in the heat storage cavity 34) to finally heat the washing liquid in the heat storage cavity 34.
In the present embodiment, the heat exchange tube of the second heat exchange device 23 is sleeved with a refrigerant transport tube. Thus, the heat exchange efficiency between the refrigerant conveying pipe and the heat exchange pipe can be improved to increase the temperature rising speed of the washing liquid in the heat storage cavity 34. In the present embodiment, the second heat exchange device 23 may employ a double pipe condenser. It will be appreciated that in other embodiments, the heat exchange ring and the refrigerant conveying pipe may not be sleeved, and only need to be capable of performing heat exchange, and the present invention is not limited in particular.

Referring to fig. 5 and 6, in some embodiments, the air conditioning washing appliance 100 includes a first stop valve 26, the first stop valve 26 is disposed in a pipeline between the heat exchange tube and the heat storage chamber 34, the first stop valve 26 switches on the circulation circuit 25 when the air conditioning system 20 is running, and the first stop valve 26 switches off the circulation circuit 25 when the air conditioning system 20 is closed.
Thus, when the air conditioning system 20 is turned off, heat loss caused by circulating the heated washing liquid in the heat storage chamber 34 in the circulation loop 25 can be avoided.
Referring to fig. 6, in some embodiments, the air-conditioning washing appliance 100 further includes a water circulation pump 27, the water circulation pump 27 is disposed in a pipeline between the heat exchange tube and the heat storage chamber 34, when the air-conditioning system 20 is running, the water circulation pump 27 is turned on, and when the air-conditioning system 20 is turned off, the water circulation pump 27 is turned off.
Thus, when the air conditioning system 20 is in operation, the circulating water pump 27 is turned on, so that the circulation speed of the washing liquid in the heat storage cavity 34 in the circulation loop 25 can be increased, the washing liquid in the heat storage cavity 34 can absorb the heat released 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 heat storage structure 30 and the second heat exchanging device 23 stop exchanging heat, and the circulating water pump 27 is turned off.
In the examples shown in fig. 5 and 6, the arrows on the circulation circuit 25 indicate the circulation flow direction of the washing liquid in the circulation circuit 25. It will be appreciated that the direction of flow of the wash liquid in the circulation loop 25 is merely exemplary and that the direction of flow may be reversed from that shown.
In some embodiments, the air conditioning washing appliance 100 further includes a second water inlet pipe 50, the second water inlet pipe 50 is connected to the housing 33, and the second water inlet pipe 50 is connected to the heat storage chamber 34.
In this manner, the second inlet conduit 50 may supplement the thermal storage chamber 34 with a wash fluid (i.e., the thermal storage medium of the thermal storage structure 30).
Specifically, the second water inlet pipe 50 is provided with a water inlet switch 51, when the air conditioning system 20 is in operation, the water inlet switch 51 is turned on, water enters the heat storage cavity 34 through the second water inlet pipe 50, and when water is fed for a period of time or when the water level of the heat storage cavity 34 reaches a certain height, the water inlet switch 51 is turned off, and water feeding is stopped. It will be appreciated that if it is detected that the wash liquid in the heat storage chamber 34 is insufficient to meet the need to circulate in the circulation loop 25 before the air conditioning system 20 is operated, a certain amount of water is required to be advanced before the air conditioning system 20 is turned on.
Referring to fig. 5 and 6, in some embodiments, a water inlet pump 28 is also disposed in the pipeline between the cavity 11 and the heat storage cavity 34, and the water inlet pump 28 is capable of delivering the washing liquid in the heat storage cavity 34 to the cavity 11.
In this way, the water inflow rate from the heat accumulation chamber 34 into the chamber 11 of the washing system 10 can be increased.
Specifically, during operation of the washing system 10, the heated washing liquid in the heat storage chamber 34 may be pumped into the chamber 11 by the water inlet pump 28 and then delivered to the spray arm assembly 13 via the wash pump 12.
It will be appreciated that in the examples shown in fig. 5 and 6, the air conditioning type washing appliance 100 may directly supplement the heat storage chamber 34 by means of the second water inlet pipe 50 without providing the water inlet pump 28, so that the hot water in the heat storage chamber 34 enters the chamber 11 of the washing system 10.
Furthermore, it will be appreciated that in some embodiments, the water inlet pump 28 is also capable of delivering the wash liquid within the chamber 11 to the thermal storage chamber 34 for storage.
Specifically, when the washing electric appliance 100 needs to drain water, for example, when the washing time sequence of the washing electric appliance 100 is finished and the washing liquid in the heat storage cavity 34 is basically consumed, the water inlet pump 28 can pump the filtered washing liquid in the cavity 11 into the heat storage cavity 34 again for storage, and then the washing liquid can be recycled. In this way, the heat storage chamber 34 can both supply hot water to the washing appliance 100 and recover and store the discharged water, and the washing appliance 100 does not need to provide an additional water storage device to recover and store the discharged water, thereby reducing the volume of the washing appliance 100 and manufacturing costs.
Referring to fig. 5 and 6 again, in some embodiments, the air-conditioning washing appliance 100 further includes a second stop valve 29, where the second stop valve 29 is disposed in a pipeline between the cavity 11 and the heat storage chamber 34, and the second stop valve 29 is used to conduct the pipeline between the cavity 11 and the heat storage chamber 34 when the washing system 10 is in operation, and to intercept the pipeline between the cavity 11 and the heat storage chamber 34 when the washing system 10 is closed.
Specifically, when the washing system 10 is turned off, no water washing is required, and the second shut-off valve 29 cuts off the piping between the chamber 11 and the heat storage chamber 34, so that the washing liquid in the heat storage chamber 34 can be prevented from entering the chamber 11.
In some embodiments, the air-conditioning washing appliance 100 includes a water softener (not shown) disposed on a pipe between the chamber 11 and the heat storage chamber 34.
Specifically, the washing liquid flowing out of the heat storage chamber 34 flows through the water softener first, is softened by the water softener, and then enters the chamber 11. Thus, the scaling phenomenon in the air-conditioning type washing electric appliance 100 and the waterway can be avoided, and the service life of the air-conditioning type washing electric appliance 100 is reduced.
It will be appreciated that in other embodiments, the water softener may be disposed on the second water inlet pipe 50, and the water entering from the second water inlet pipe 50 is softened by the water softener before entering the heat storage chamber 34, and heated in the heat storage chamber 34 before entering the chamber 11.

In this way, the temperature detection device can monitor the temperature of the wash liquor in real time as water is fed through the thermal storage chamber 34. When the temperature of the washing liquid is low, the pipeline between the cavity 11 and the heat storage cavity 34 can be cut off by closing the second stop valve 29, so that the influence on the washing effect caused by the too low temperature of the water entering the cavity 11 can be prevented.
It will be appreciated that in other embodiments, the temperature sensing port 345 may also be provided on the line between the heat exchange tube and the heat storage chamber 34, i.e. on the circulation loop 25.

When the air conditioning system 20 is operated alone, the heat storage structure 30 exchanges heat with only the second heat exchange device 23, and the heat storage structure 30 stores heat. In the separate operation of the washing system 10, the heat storage structure 30 exchanges heat with the washing liquid (the heat storage medium of the heat storage structure 30 is not water) or directly supplies the heated washing liquid (the heat storage medium of the heat storage structure 30 is water), and the heat in the heat storage structure 30 comes from the heat stored in the previous operation of the air conditioning system 20. In some examples, the air-conditioning washing appliance 100 may be further provided with an electric heating device, and the electric heating device may be turned on to perform auxiliary heating of the washing liquid when the heat in the heat storage structure 30 is insufficient to heat the washing liquid to a desired temperature.
