Description

Technical Field

[0001] The present invention relates to the technical field of household washing appliances, and particularly provides a heat pump type washing and drying integrated machine; Background Art

[0002] With the development of the economy and the improvement of the social consumption structure, people's demand for a high-quality life is becoming stronger and stronger, and washing and drying integrated machines have begun to enter thousands of households; consumers not only require the washing and drying integrated machine to wash clothes cleanly and dry them thoroughly, but also hope that it is more power-saving and energy-efficient.

[0003] Although the existing washing and drying integrated machines perform well in clothes drying, there is still room for improvement in energy consumption control. Especially in the washing stage, traditional washing and drying integrated machines usually use PTC heaters to heat the washing water. This method not only has low thermal efficiency, but also causes the washing and drying integrated machine to consume a large amount of electric energy during the heating process, making it difficult to reduce the overall operating energy consumption.

[0004] The existing heat pump washing and drying integrated machine (CN119332442A) improves the drying efficiency by setting a fresh air inlet on the second drying air duct to introduce external dry fresh air, and the design of the fresh air inlet position avoids the influence of the fresh air temperature by the evaporator; at the same time, the device sets a fresh air outlet on the first drying air duct, and cooperates with the exhaust duct and the electric control valve to effectively manage the air pressure in the drum module and avoid the safety hazards caused by excessive air pressure; in addition, the layout design of the heat pump module makes reasonable use of the space in the box body, improves the heat exchange efficiency, and further improves the drying effect. However, this heat pump washing and drying integrated machine only enables the heat pump drying stage during the clothes drying stage, and still uses a PTC heater to prepare hot water during the washing stage. Limited by the heat conversion efficiency of the PTC heater, it is difficult to further reduce the operating energy consumption of the washing and drying integrated machine. Summary of the Invention

[0005] The purpose of the present invention is to provide a heat pump type washing and drying integrated machine, which cleverly uses a heat pump system to heat the washing water during the washing stage, replacing the traditional PTC heater heating method. At the same time, by optimizing the design of the air duct component and the water circuit component, the energy efficiency ratio of the heat pump system is further improved, thereby effectively reducing the power consumption of the heat pump washing and drying integrated machine during the heating of the washing water stage. The present invention not only realizes the high-efficiency and energy-saving operation of the heat pump washing and drying integrated machine during the washing stage and the drying stage, but also significantly reduces the use cost of consumers, providing a more energy-saving and environment-friendly heat pump washing and drying integrated machine solution for the home appliance market.

[0006] The present invention is achieved by at least one of the following technical solutions.

[0010] The air duct assembly includes a return air duct, an air treatment chamber, a drying centrifugal fan, a supply air duct, an external circulation air duct inlet air duct, a hot water production axial flow fan, and an external circulation air duct outlet air duct. The first drying condenser and the second drying evaporator are located in the air treatment chamber. The air treatment chamber is communicated with the drum through the supply air duct and the return air duct. The drying centrifugal fan is located between the first drying condenser and the second drying evaporator.

[0011] The water circuit assembly includes a water outlet pipe, a water inlet pipe, and a circulation water pump. The water outlet pipe and the water inlet pipe are connected through the circulation water pump.

[0012] The drum assembly includes a drum for containing clothes, a driving motor, a water outlet and a water inlet, a return air port and a supply air port. The driving motor is connected to the drum. In the washing stage, the driving motor drives the drum to rotate to wash the clothes and spin-dry the water. In the drying stage, the driving motor drives the drum to rotate to increase the contact area between the clothes and the hot air. The drum is connected to the water outlet pipe through the water outlet and to the water inlet pipe through the water inlet. The hot water production axial flow fan is located on one side of the hot water production evaporator. In the washing stage, under the drive of the hot water production axial flow fan, the air in the external environment exchanges heat with the hot water production evaporator through the external circulation air duct inlet air duct and is then discharged back to the external environment through the external circulation air duct outlet air duct. In the drying stage, under the drive of the drying centrifugal fan, the wet air in the drum enters the air treatment chamber through the return air duct and then returns to the drum through the supply air duct.

[0038] The following further describes a heat pump type washing and drying integrated machine of the present invention in conjunction with the attached drawings and specific embodiments;

[0039] Such as Figures 1 to 7As shown in the figure, a heat pump type washing and drying integrated machine according to this embodiment includes: a box body assembly 100, a heat pump system 200, an air duct assembly 300, a water circuit assembly 400, and a cylinder body assembly 500; the box body assembly 100 covers the outside of the cylinder body assembly, the heat pump system, the air duct assembly, and the water circuit assembly, providing structural support for the entire heat pump type washing and drying integrated machine.

[0040] The box body assembly 100 includes a control area 101 for controlling the washing and drying integrated machine and a containing area 102, and the containing area 102 installs the cylinder body assembly 500, the heat pump system 200, the air duct assembly 300, and the water circuit assembly 400.

[0041] The cylinder body assembly 500 cleans clothes and wrings out moisture during the washing stage, and promotes the drying of clothes during the drying stage. As Figure 2 shown, the cylinder body assembly 500 includes a drum 501 for containing clothes, a driving motor 502, a water outlet 503, a water inlet 504, a return air outlet 505, and a supply air outlet 506. Among them, the water outlet 503 and the water inlet 504 are located on the side of the drum 501, and the return air outlet 505 and the supply air outlet 506 are located on the side of the drum 501; the driving motor 502 is located at the bottom of the drum 501 and is connected to the drum 501. During the washing stage, the driving motor 502 drives the drum 501 to rotate to clean clothes and wring out moisture. During the drying stage, the driving motor 502 drives the drum 501 to rotate to increase the contact area between clothes and hot air, improving the drying effect of clothes.

[0042] During the washing stage, the driving motor provides power for the rotation of the drum. During the rotation of the drum, through the internal mechanical force, the clothes are continuously tumbled and rubbed in the drum, thereby achieving effective cleaning of the clothes. At the same time, the high-speed rotation of the drum can also generate a strong centrifugal force to throw out the moisture in the clothes, achieving the effect of wringing dry and preparing for the subsequent drying process; during the drying stage, the driving motor also drives the drum to rotate, but at this time, the rotation speed and direction of the drum may be adjusted according to the drying requirements. Through the rotation of the drum, the clothes are continuously turned and unfolded in the drum, thus significantly increasing the contact area between the clothes and the hot air. This not only helps to improve the drying efficiency, but also makes the clothes receive more uniform heat, avoiding damage to the clothes caused by local overheating, and effectively improving the drying effect and wearing comfort of the clothes.

[0043] The drum 501 is connected to the water outlet pipe 401 through the water outlet 503, and the drum 501 is connected to the water inlet pipe 403 through the water inlet 504.

[0044] The drum 501 is connected to the return air duct 301 through the return air outlet 505, and the drum 501 is connected to the supply air duct 304 through the supply air outlet 506.

[0045] As shown Figure 3 in the figure, the heat pump system 200 heats the washing water during the washing stage and dries and dehumidifies the clothes in the drum during the drying stage; the heat pump system 200 includes a compressor 201, a first drying condenser 202, a drying throttle valve 203, a second drying evaporator 204, a hot water production condenser 205, a hot water production throttle valve 206, a hot water production evaporator 207, a low-pressure three-way valve 208, and a high-pressure three-way valve 209; as shown Figure 2 in the figure, the output end of the compressor 201, the input end of the first drying condenser 202, and the input end of the hot water production condenser 205 are connected to each other through the high-pressure three-way valve 209; the output end of the hot water production condenser 205 is connected to the input end of the hot water production evaporator 207 through the hot water production throttle valve 206; the output end of the first drying condenser 202 is connected to the input end of the second drying evaporator 204 through the drying throttle valve 203; the output end of the second drying evaporator 204, the output end of the hot water production evaporator 207, and the input end of the compressor 201 are connected to the low-pressure three-way valve 208. As an embodiment, the hot water production condenser 205 adopts a double-pipe heat exchanger that improves space utilization and heat exchange area. The second drying evaporator 204 and the first drying condenser 202 adopt a micro-channel heat exchanger that increases the heat exchange area and reduces the refrigerant charge.

[0046] Furthermore, all components of the heat pump system 200 are connected by copper pipes. This connection method not only ensures the system's sealing performance and durability but also utilizes the good heat conduction performance of copper pipes to improve the heat exchange efficiency. The outer surfaces of the hot water production condenser 205 and each section of copper pipe are wrapped with heat insulation materials, effectively reducing heat loss during transmission and further improving the energy efficiency ratio of the system. The use of heat insulation materials also reduces the noise level during equipment operation and enhances the user's comfort.

[0047] As shown Figure 4 in the figure, the air duct assembly 300 includes a return air duct 301, an air treatment chamber 302, a drying centrifugal fan 303, a supply air duct 304, an external circulation air duct inlet air duct 305, a hot water production axial flow fan 306, and an external circulation air duct outlet air duct 307; the first drying condenser 202 and the second drying evaporator 204 are located in the air treatment chamber 302, and the air treatment chamber 302 communicates with the return air duct 301 and the drum 501 through the supply air duct 304; the drying centrifugal fan 303 is located between the first drying condenser 202 and the second drying evaporator 204.

[0048] The axial flow fan 306 for making hot water is located on one side of the evaporator 207 for making hot water. During the washing stage, driven by the axial flow fan 306 for making hot water, the air in the external environment exchanges heat with the evaporator 207 for making hot water after passing through the air inlet duct 305 of the external circulation air duct, and then is discharged back to the external environment through the air outlet duct 307 of the external circulation air duct. During the drying stage, driven by the centrifugal fan 303 for drying, the wet air in the drum 501 enters the air treatment chamber 302 through the return air duct 301, and then returns to the drum 501 through the air supply duct 304.

[0049] As an embodiment, the outer surfaces of the return air duct 301, the air treatment chamber 302, and the air supply duct 304 are all wrapped with heat insulation materials. The heat insulation materials on the outer surfaces of these duct components can effectively reduce the loss of heat during air transmission, ensure that the temperature of the hot air is maintained at a relatively high level, thereby improving the drying efficiency. At the same time, the use of heat insulation materials also reduces the noise level during equipment operation and enhances the user's comfort.

[0050] The water circuit component 400 transports the washing water in the drum 501 to the condenser 205 for making hot water during the washing stage and transports the heated washing water back to the drum 501. The water circuit component 400 includes a water outlet pipe 401, a water inlet pipe 403, and a circulation water pump 402. The water outlet pipe 401 and the water inlet pipe 403 are connected by the circulation water pump 402, and the outer surfaces of the water outlet pipe 401 and the water inlet pipe 403 are both wrapped with heat insulation materials. The water outlet pipe 401 is connected to the water inlet of the condenser 205 for making hot water, and the water inlet pipe 401 is connected to the water outlet of the condenser 205 for making hot water. During the washing stage, the circulation flow path of the washing water is as Figure 5 shown by the dotted line in the figure. Driven by the circulation water pump 402, the washing water in the drum 501 flows through the water outlet pipe 401 and then enters the condenser 205 for making hot water to exchange heat with the high-temperature and high-pressure gaseous refrigerant. After heat exchange and temperature rise, the washing water flows through the water inlet pipe 403 and then returns to the drum 501.

[0051] During the washing stage, driven by the circulating water pump, the washing water in the drum enters the condenser for hot water through the water outlet pipe, and the washing water heated after heat exchange returns to the drum through the water inlet pipe. Specifically, the circulating water pump plays a crucial role during the washing process. By generating a stable water flow power, it extracts the used washing water in the drum from the water outlet pipe and transports it to the condenser for hot water. Inside the condenser, the heat generated by the heat pump system is transferred to the washing water, significantly increasing its temperature. After sufficient heat exchange and temperature rise, the washing water is then transported back into the drum through the water inlet pipe to continue participating in the clothing washing process. This cyclic process ensures the rational utilization of water resources and the effective reduction of energy consumption, providing strong support for the energy-saving operation of the entire heat pump washing and drying integrated machine.

[0052] As an embodiment, the condenser for making hot water adopts a double-pipe heat exchanger. The evaporator for making hot water adopts a finned-tube heat exchanger or a microchannel heat exchanger. The first condenser for drying and the second evaporator for drying adopt microchannel heat exchangers. The throttle valve for drying and the throttle valve for making hot water adopt an electronic expansion valve or a thermostatic expansion valve and a capillary tube. The electronic expansion valve spontaneously adjusts the refrigerant flow rate according to the actual operating conditions of the heat pump system, improving the energy efficiency ratio and operating stability of the heat pump system.

[0053] As Figure 5 As shown, the working principle of the heat pump washing and drying integrated machine of the present invention during the washing stage is as follows: From the perspective of the circulating flow path of air, the axial flow fan 306 for making hot water drives the outside ambient air to pass through the air inlet duct 305 of the outer circulation air duct to the evaporator 207 for making hot water for heat exchange, and the cooled air then returns to the outside ambient through the air outlet duct 307 of the outer circulation air duct; From the perspective of the circulating flow path of the refrigerant, the low-temperature and low-pressure gas-liquid two-phase mixed refrigerant in the evaporator 207 for making hot water absorbs heat and evaporates and then enters the compressor 201. The high-temperature and high-pressure gaseous refrigerant compressed by the compressor 201 condenses and releases heat in the condenser 205 for making hot water, and after being throttled and depressurized by the throttle valve 206 for making hot water, it returns to the evaporator 207 for making hot water to start the next cycle; From the perspective of the circulating flow path of the washing water, the washing water in the drum 501 is driven by the circulating water pump 402, flows through the water outlet pipe 401 and then enters the condenser 205 for hot water. The washing water heated after heat exchange flows through the water inlet pipe 403 and then returns to the drum 501 to start the next cycle. Through the above-mentioned circulating flows of air, refrigerant, and washing water, the heat energy of the ambient air can be absorbed by the evaporator 207 for making hot water, and then the absorbed heat energy can be transferred to the washing water through the condenser 205 for making hot water, so that the washing water is heated from the initial water temperature to the required target temperature. Compared with directly heating the washing water by a traditional PTC heater, the heat pump washing and drying integrated machine of the present invention can save more electric energy during the washing stage.

[0054] As Figure 6 shown, the working principle of the heat pump type washing and drying integrated machine of the present invention in the drying stage is as follows: From the perspective of the circulating flow path of the wet air, the centrifugal fan 303 for drying drives the wet air in the drum 501 into the air treatment chamber 302. The wet air first cools to the dew point temperature on the surface of the second evaporator 204 for drying, and then starts to precipitate liquid condensate droplets. Then it passes through the first condenser 202 for drying, and after heat exchange and temperature rise, it is transformed into high-temperature dry air. Finally, it returns to the drum 501 to promote the evaporation of moisture in the wet clothes, and then is transformed into wet air to start the next cycle; From the perspective of the circulating flow path of the refrigerant, the low-temperature and low-pressure gas-liquid two-phase mixed refrigerant in the second evaporator 204 for drying absorbs heat and evaporates and then enters the compressor 201. The high-temperature and high-pressure gaseous refrigerant compressed by the compressor 201 condenses and releases heat in the first condenser 202 for drying, and returns to the second evaporator 204 for drying after throttling and pressure reduction by the throttle valve 203 for drying, and then starts the next cycle; Through the above-mentioned circulating flow of the wet air and the refrigerant, the moisture in the wet clothes can be transformed into the condensate water collected at the second evaporator 204 for drying, so as to realize the drying of the wet clothes.

[0055] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, improvements, etc. made within the spirit of the present invention shall be included in the protection scope of the present invention.
