The following describes a washing appliance 1 according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 1 to 5, the washing appliance 1 according to the embodiment of the present invention includes an inner container 100, an air duct assembly 200, and a heat pump system 300.

The inner container 100 has an air inlet 101 and an air outlet 102, the air duct assembly 200 includes a first air duct 210, an inlet of the first air duct 210 is communicated with the air outlet 102, and an outlet of the first air duct 210 is communicated with the air inlet 101. The heat pump system 300 includes a compressor 310, a throttle device 320, an air-cooled condenser 330, and an evaporator 340, wherein at least a portion of the evaporator 340 is disposed in the first air duct 210, so that the evaporator 340 exchanges heat with air flowing therethrough. The air duct assembly 200 further includes a second air duct 220, an inlet of the second air duct 220 is communicated with the air outlet 102, an outlet of the second air duct 220 is communicated with the first air duct 210, and at least a portion of the air-cooled condenser 330 is disposed in the first air duct 210 and located downstream of the second air duct 220 in the flowing direction of the air, so that the air-cooled condenser 330 and the flowing air can exchange heat.

Specifically, in the flow direction of the gas, the communication between the outlet of the second air duct 220 and the first air duct 210 is located upstream of the air-cooled condenser 330 and downstream of the evaporator 340. That is, after the air in the first air duct 210 is dehumidified by the evaporator 340, the air can be merged with the air in the second air duct 220, and before the air flows into the inner container 100 through the air inlet 101, the air in the first air duct 210 and the air in the second air duct 220 are heated by the air-cooled condenser 330.

It should be understood that the phrase "the air-cooled condenser 330 is located downstream of the second air duct 220 in the flowing direction of the air" means that the air flowing out of the inner container 100 flows through the second air duct 220 first and then flows through the air-cooled condenser 330. The phrase "the communication between the outlet of the second air duct 220 and the first air duct 210 is located upstream of the air-cooled condenser 330 in the air flowing direction" means that the air flowing out of the liner 100 flows through the communication between the outlet of the second air duct 220 and the first air duct 210 and then flows through the air-cooled condenser 330.

According to the utility model discloses washing electrical apparatus 1, through setting up heat pump system 300, can utilize heat pump system 300 to absorb the heat in the external environment, heats the gas of circulation in the wind channel subassembly 200 or the washing liquid in the washing electrical apparatus 1, after converting the energy conversion of low-grade into high-grade heat energy, releases in gas or washing liquid, reaches high-efficient, low energy consumption and heats the purpose. Compared with an electric heating mode, the heat pump system 300 can convert low-grade energy into high-grade heat energy through the actions of the compressor 310, the throttling device 320, the air-cooled condenser 330 and the evaporator 340, and the low-grade heat energy is released into gas in the air duct assembly 200 or washing liquid of the washing electric appliance 1 after being converted into the high-grade heat energy through the processes of compression, condensation heat release, throttling expansion and evaporation heat absorption by the aid of the refrigerant in the heat pump system 300, so that the purposes of high-efficiency and low-energy-consumption heating are achieved, an energy-saving effect is remarkable, and the use energy consumption of the washing electric appliance 1.

In addition, by providing the first air duct 210 and the second air duct 220 in the air duct assembly 200, the high humidity air flowing out of the liner 100 can flow into the first air duct 210 and the second air duct 220 through the air outlet 102. When a part of the high humidity gas flows through the evaporator 340 in the first air duct 210, the water vapor in the high humidity gas is condensed into a liquid state to reduce the humidity of the gas, so as to dry and dehumidify the gas, and at this time, the temperature of the gas is reduced, and the high humidity gas becomes dry cold air. The other part of the high humidity gas can directly flow through the second air duct 220, and after the high humidity gas is merged with the dry and cold gas treated in the first air duct 210, the mixed gas flows through the air-cooled condenser 330 to be heated and heated, and then flows back to the inner container 100 through the air inlet 101, so as to be convenient for drying the tableware in the inner container 100.

Therefore, by arranging the first air duct 210 and the second air duct 220, the humidity and the temperature of the high-humidity gas flowing out from the inner container 100 can be adjusted, so that the gas flowing back to the inner container 100 has a proper temperature range and a proper humidity range, the gas can smoothly dry the tableware in the inner container 100, and the drying effect of the washing appliance 1 is improved. Meanwhile, the unnecessary power consumption of the washing appliance 1 caused by drying and cooling of all high-humidity gas flowing out of the inner container 100 can be avoided, and in the process of drying tableware, the gas can be ensured to circulate in the air duct assembly 200 and the inner container 100, so that impurities such as dust in the external environment are prevented from entering the inner container 100 to pollute the inner container 100 and the tableware in the inner container 100, and the drying safety and reliability of the tableware are improved.

That is, a part of the gas flowing out of the inner container 100 passes through the evaporator 340, and the other part of the gas does not pass through the evaporator 340, and the two parts of the gas are mixed before the air-cooled condenser 330 and then enter the inner container 100 through the air inlet 101, so that the total amount of the part of the gas flowing through the evaporator 340 is controlled, the humidity and the temperature of the gas flowing back to the inner container 100 are conveniently controlled, and the unit dehumidification capacity of the gas is improved.

Therefore, according to the utility model discloses washing electrical apparatus 1 has effectual, the drying process safe and reliable and the energy consumption low grade advantage of drying to the tableware.

In some embodiments of the present invention, as shown in fig. 1 to 5, a washing appliance 1 according to embodiments of the present invention includes an inner container 100, an air duct assembly 200, and a heat pump system 300.

Specifically, as shown in fig. 3, the first air duct 210 includes a main air duct 211, an inflow section 212, and an outflow section 213, and both ends of the main air duct 211 communicate with the inflow section 212 and the outflow section 213, respectively. Wherein, the outlet of the second air duct 220 is communicated with the outflow section 213, and at least a part of the air-cooled condenser 330 is arranged in the outflow section 213. Therefore, the first air duct 210 is conveniently communicated with the inner container 100 through the inlet and the outlet to form a circulation loop, and the air in the first air duct 210 and the air in the second air duct 220 are conveniently converged and then flow through the air-cooled condenser 330 for heating.

Specifically, the first air duct 210 includes a main air duct 211, an inflow section 212, and an outflow section 213, both ends of the main air duct 211 are respectively communicated with the inflow section 212 and the outflow section 213, an inlet of the first air duct 210 is formed on the inflow section 212, and the inflow section 212 is communicated with the air outlet 102 through the inlet of the first air duct 210. The outlet of the first air duct 210 is formed on the outflow section 213, and the outflow section 213 communicates with the air inlet 101 through the outlet of the first air duct 210. The evaporator 340 is disposed in the main duct 211 or the outflow section 213. The inlet of the second air duct 220 is communicated with the first air duct 210, the outlet of the second air duct 220 is communicated with the outflow section 213, at least a part of the air-cooled condenser 330 is arranged in the outflow section 213, in the flowing direction of the air, the connection position of the second air duct 220 and the outflow section 213 is positioned at the upstream of the air-cooled condenser 330, and the connection position of the second air duct 220 and the outflow section 213 is positioned at the downstream of the evaporator 340. In other words, the air in the first air duct 210 flows through the air-cooled condenser 330 after flowing through the evaporator 340, and then flows back to the inner container 100, and the air in the second air duct 220 flows through the air-cooled condenser 330 and then flows back to the inner container 100.

In some embodiments, as shown in fig. 3, the inlet of the second air duct 220 is in communication with the inflow section 212, such that the inlet of the second air duct 220 is in communication with the outlet 102 via the inflow section 212. In this way, the high-humidity gas in the inner container 100 can be guided to the main air duct 211 and the second air duct 220 of the first air duct 210 through the inflow section 212, so that the first air duct 210 and the second air duct 220 can be conveniently communicated with the inner container 100 to form a circulation loop.

In other embodiments, the inlets of the inflow section 212 and the second air duct 220 are directly connected to the air outlet 102. Therefore, the high-humidity gas in the inner container 100 can separately flow into the first air duct 210 and the second air duct 220, and the influence of the mutual interference of the gas in the first air duct 210 and the second air duct 220 on the normal flow of the gas is avoided.

Alternatively, the flow area of the main duct 211 is larger than the flow area of the second duct 220. Therefore, most of the high-humidity gas flowing out from the inner container 100 can be dried and dehumidified through the evaporator 340, so that the humidity of the gas is reduced, and the drying effect of the gas on tableware is improved.

In some embodiments, as shown in FIG. 3, the air duct assembly 200 includes a first vent 230 and a second vent 240, and the first vent 230 and the second vent 240 are respectively in communication with the outside. The washing appliance 1 further includes a first switch 410 and a second switch 420, the first switch 410 is used for controlling the on-off of the main air duct 211 and the first air vent 230 or the inflow section 212, and the second switch 420 is used for controlling the on-off of the main air duct 211 and the second air vent 240 or the outflow section 213. Thus, the main air duct 211 of the first air duct 210 can be respectively communicated with the external environment or the liner 100 as a circulation loop according to requirements, thereby facilitating the flexible change of the circulating air in the first air duct 210 and improving the functionality and the applicability of the air duct assembly 200.

Alternatively, the first and

second vents

230 and 240 may be provided at positions where a side panel, a skirting board, or a housing of the washing appliance 1, etc. is not shielded by a cabinet or foreign objects. The air inlet 101 and the air outlet 102 may be disposed on a side wall surface or a top surface of the inner container 100, or the like, so as to be conveniently communicated with the inner container 100.

Specifically, as shown in fig. 3, the washing appliance 1 further includes a washing system 500, and the heat pump system 300 further includes a water-cooled condenser 350, wherein the water-cooled condenser 350 is used for heating the washing liquid in the washing system 500. The washing appliance 1 has a drying state and a heating state, and when the washing appliance 1 is in the drying state, the first switch 410 communicates the main air duct 211 with the inflow section 212 and closes the first air vent 230, and the second switch 420 communicates the main air duct 211 with the outflow section 213 and closes the second air vent 240. When the washing appliance 1 is in a heating state, the first switch 410 communicates the main air duct 211 with the first ventilation opening 230 and separates the main air duct 211 from the inflow section 212, and the second switch 420 communicates the main air duct 211 with the second ventilation opening 240 and separates the main air duct 211 from the outflow section 213.

When the washing appliance 1 is in a heating state, the air duct assembly 200 can be communicated with the external environment, so that the evaporator 340 can collect heat of air in the external environment, the heating efficiency of the heat pump system 300 is improved, and the washing effect of the washing appliance 1 is improved.

For example, the evaporator 340 is disposed in the main air duct 211, when the washing appliance 1 is in a heating state and needs to heat the washing liquid, the first switch 410 and the second switch 420 can enable two ends of the main air duct 211 to be respectively communicated with the external environment through the first air vent 230 and the second air vent 240, so that the air in the external environment can continuously flow through the evaporator 340, and the evaporator 340 can better absorb the heat of the air in the external environment. When the washing appliance 1 is in a drying state and tableware in the inner container 100 needs to be dried, the first switch 410 and the second switch 420 can enable two ends of the main air duct 211 to be respectively communicated with the inflow section 212 and the outflow section 213, so that a circulating inner loop is formed between the air duct assembly 200 and the inner container 100, and the evaporator 340 can be used for drying and dehumidifying high-humidity gas flowing out of the inner container 100, so that the treated gas can flow back to the inner container 100 to dry the tableware.

Optionally, as shown in fig. 3, the washing appliance 1 further comprises a washing system 500, and the heat pump system 300 comprises a water-cooled condenser 350, wherein the water-cooled condenser 350 is used for heating the washing liquid in the washing system 500. This allows the water cooled condenser 350 to heat the washing liquid in the washing system 500, and the high temperature washing liquid washes away the contaminants on the dishes and brings heat to the dishes, so that the washing appliance 1 can achieve a high washing rate and drying rate in a short washing time.

In some embodiments, as shown in fig. 2, the compressor 310, the throttling device 320, the air-cooled condenser 330, the water-cooled condenser 350, and the evaporator 340 are arranged in series, and the water-cooled condenser 350 is located upstream of the air-cooled condenser 330 in the flow direction of the heat exchange medium in the heat pump system 300. Thus, the heat exchange medium after absorbing heat flows through the water-cooled condenser 350 and then flows through the air-cooled condenser 330, so that the heat pump system 300 can be ensured to preferentially heat the washing liquid in the washing system 500 through the water-cooled condenser 350, and the washing effect of the washing appliance 1 is ensured.

It should be understood that "the water-cooled condenser 350 is located upstream of the air-cooled condenser 330 in the flowing direction of the heat exchange medium in the heat pump system 300" means that the heat exchange medium after absorbing heat by the evaporator 340 flows through the water-cooled condenser 350 and then flows through the air-cooled condenser 330.

Specifically, the evaporator 340, the compressor 310, the water-cooled condenser 350, the air-cooled condenser 330, and the throttle device 320 are connected in series in this order to form a circulation circuit. The throttling device 320 may be an expansion valve, and further the throttling device 320 may be an electronic expansion valve.

In other embodiments, as shown in fig. 3, the heat pump system 300 includes a first branch 361, a second branch 362 and a third branch 363, and both ends of the second branch 362 and the third branch 363 are respectively communicated with the first branch 361. The compressor 310, the evaporator 340, and the throttle device 320 are connected to a first branch 361, the water-cooled condenser 350 and the first on-off valve 323 are connected to a second branch 362, and the air-cooled condenser 330 and the second on-off valve 324 are connected to a third branch 363. Therefore, when the heat pump system 300 heats the washing liquid, the first on-off valve 323 can be connected and the second on-off valve 324 is disconnected, and no heat exchange medium flows in the third branch 363, so that the pipeline flow resistance of the heat pump system 300 can be reduced, and the energy consumption of the heat pump system 300 when the washing liquid is heated can be reduced. In the stage of drying or keeping the dishes, the second on-off valve 324 can be connected and the first on-off valve 323 can be disconnected, and at this time, no heat exchange medium flows in the second branch 362, so that the pipeline flow resistance of the heat pump system 300 can be reduced, and the energy consumption of the heat pump system 300 in the stage of drying and keeping the dishes can be reduced. Thereby, the energy efficiency of the washing appliance 1 is facilitated to be improved and the energy consumption is reduced.

In other embodiments, as shown in fig. 4, the throttling device 320 includes a first expansion valve 321 and a second expansion valve 322, the heat pump system 300 includes a first branch 361, a second branch 362 and a third branch 363, and both ends of the second branch 362 and the third branch 363 are respectively communicated with the first branch 361. The compressor 310 and the evaporator 340 are connected to a first branch 361, the water-cooled condenser 350 and the first expansion valve 321 are connected to a second branch 362, and the air-cooled condenser 330 and the second expansion valve 322 are connected to a third branch 363. Thus, a dual throttle device 320 system can be constructed using the first expansion valve 321 and the second expansion valve 322. When the heat pump system 300 heats the washing liquid, the first expansion valve 321 enters a normal working state, the second expansion valve 322 is closed or the opening degree is in a minimum state, and at this time, no heat exchange medium flows in the third branch 363, so that the flow resistance of the pipeline of the heat pump system 300 is reduced, and the energy consumption of the heat pump system 300 when the washing liquid is heated is reduced. In the stage of drying or storing the dishes, the second expansion valve 322 enters a normal working state, the first expansion valve 321 is closed or has a minimum opening degree, and no heat exchange medium flows in the second branch 362, so that the pipeline flow resistance of the heat pump system 300 is reduced, and the energy consumption of the heat pump system 300 in the drying and storing stage is reduced. Therefore, the energy efficiency of the washing appliance 1 is improved, and the energy consumption is reduced.

Specifically, as shown in fig. 1, the washing system 500 includes a spray arm assembly 510, a water collecting member 520 and a washing pump 530, the spray arm assembly 510 is disposed in the inner container 100, the water collecting member 520 is disposed in the inner container 100 and located below the spray arm assembly 510 (the up-down direction of the inner container 100 is shown in fig. 1), and the washing pump 530 is respectively communicated with the spray arm assembly 510 and the water collecting member 520. Thus, the washing liquid in the washing system 500 can be delivered to the spray arm assembly 510 by the washing pump 530, and the dishes can be continuously sprayed and washed by the spray arm assembly 510, so as to clean the dishes. The water collection member 520 may collect the washing liquid in the inner container 100 to realize the circulation flow of the washing liquid in the washing system 500.

It should be understood that the vertical direction in fig. 1 is only for convenience of describing the vertical position relationship of the inner structure of the inner container 100, and is not limited to the actual structure of the washing appliance 1.

More specifically, as shown in fig. 3, the spray arm assembly 510 includes a top spray arm 511, a middle spray arm 512, and a lower spray arm 513, and the water collecting member 520 is formed as a water collecting tub of a cup positioned at a lower portion of the inner container 100.
