[0035] To make the purpose, technical solutions and advantages of this application more clear, the following will further describe the implementation methods of this application in detail with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and are intended to be used to explain this application, and should not be understood as limiting this application.
[0036] In the description of this application, it should be understood that the terms "length", "width", "thickness", "top", "bottom", "inside", "outside", "up", "down", "left", "right", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application.
[0037] To facilitate the clear description of the technical solutions of this application, the words "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. Those skilled in the art will understand that the words "first" and "second" do not limit the quantity or order of execution, and the words "first" and "second" do not necessarily mean different.
[0038] In this application, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.
[0040] It should be noted that, in this application, words such as "in one embodiment," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "in one embodiment," "exemplarily," or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a concrete manner.
[0041] See Figure 1 , a diagram of an existing heat pump dryer system. The heat pump system operates as follows: After high-temperature, high-pressure gaseous refrigerant releases heat through condenser 2, it becomes high-pressure, medium-temperature liquid refrigerant. It is then cooled and reduced in pressure by throttling element 3 to a low-temperature, low-pressure, two-phase gas-liquid refrigerant. After entering evaporator 4, it absorbs heat and vaporizes into medium-temperature, low-pressure gaseous refrigerant. This is then compressed by compressor 1 to a high-temperature, high-pressure gaseous refrigerant. The circulating air within the dryer flows as follows: After passing through condenser 2, it is heated to high-temperature, dry air. It then passes through impeller 10 and enters cylinder 11, removing moisture from clothing. After cooling and condensing in evaporator 4, it flows back to condenser 2 to be heated again, repeating the cycle. Liquid water condensing on the surface of evaporator 4 falls into a water collector below evaporator 4.
[0042] When the ambient temperature is relatively low, the heat pump system's evaporation temperature decreases. The evaporation temperature refers to the temperature at which the refrigerant boils in the evaporator. This drop in evaporation temperature causes a decrease in the suction pressure of compressor 1, reducing the heat pump system's heating capacity. This in turn affects the ability of the circulating air to remove moisture from clothes as it passes through drum 11. Therefore, in low-temperature environments, the dryer's drying speed is slow. Furthermore, when the ambient temperature is relatively high, the heat pump system's compressor 1 is overloaded and may shut down, resulting in a slow drying speed.
[0043] To solve the above problem, this embodiment provides a drying system for a clothing processing device. The clothing processing device may be a dryer or a washer-dryer. The clothing processing device includes a heat pump system and a moisture absorption and dehumidification system.
[0044] See Figure 2 The heat pump system includes a compressor 1, a condenser 2, a throttling element 3 and an evaporator 4 connected in sequence. The heat pump system works as follows: the high-temperature and high-pressure gaseous refrigerant releases heat through the condenser 2 and becomes a high-pressure medium-temperature liquid refrigerant, which is cooled and reduced in pressure through the throttling element 3 to become a low-temperature and low-pressure gas-liquid two-phase refrigerant. After entering the evaporator 4 to absorb heat, it enters the compressor 1 and is compressed into a high-temperature and high-pressure gaseous refrigerant.
[0045] The dehumidification system includes a dehumidification turntable 5 and a turntable dehumidification device. Figure 2 , illustrates a dehumidification turntable 5, which is arranged between the evaporator 4 and the condenser 2, and is used to dehumidify the air passing through it.
[0046] Regarding the dehumidification turntable 5, specifically, an adsorption zone and a regeneration zone are formed on the dehumidification turntable 5. After the humid air passes through the adsorption zone of the dehumidification turntable 5, the hygroscopic material on the dehumidification turntable 5 will absorb the moisture in the air; the regeneration zone of the dehumidification turntable 5 is exposed to hot air, that is, the hot air generated by the turntable dehumidification device is blown towards the regeneration zone to evaporate the moisture on the hygroscopic material in the regeneration zone. The process of the dehumidification turntable 5 adsorbing moisture is called adsorption, and the process of evaporating moisture from the dehumidification turntable 5 is called regeneration. After the regeneration zone of the dehumidification turntable 5 is regenerated, the dehumidification turntable 5 can rotate to form an adsorption zone, so that the dehumidification turntable 5 can continuously adsorb moisture from the air passing through it. In addition, when the regeneration zone of the dehumidification turntable 5 is regenerated and the dehumidification turntable 5 rotates to form an adsorption zone, because the adsorption zone now has the heat provided by the turntable dehumidification device, the adsorption zone can heat the air passing through it.
[0047] Regarding the hygroscopic material of the dehumidification rotary disk 5 , preferably, the hygroscopic material on the dehumidification rotary disk 5 is a molecular sieve.
[0048] In this embodiment, the adsorption area of the dehumidification turntable 5 is located between the evaporator 4 and the condenser 2. The air flow passing through the evaporator 4 can flow to the condenser 2 through the adsorption area. That is, after the air is dehumidified by the evaporator 4, it can be dehumidified again through the adsorption area of the dehumidification turntable 5.
[0049] In this embodiment, the rotary disc dehumidification device includes a heater 6 and a first fan 7. Under the action of the first fan 7, air can flow through the heater 6 to the regeneration zone. Figure 2 , showing the heater 6 and the first fan 7.
[0050] The heater 6 is used to heat the air flow passing through it. The heater 6 can be an electric heating tube. When the first fan 7 is working, it blows the air flow toward the heater 6. The heater 6 heats the air passing through it into high-temperature dry air. When the high-temperature dry air passes through the regeneration zone of the dehumidification rotary disk 5, it can take away the moisture in the regeneration zone.
[0051] When the drying system provided in this embodiment is applied to a clothes processing device and the heat pump system and the moisture absorption and dehumidification system work simultaneously, see Figure 2 The circulating air within the clothing processing apparatus flows as follows: After passing through condenser 2, it is heated to high-temperature dry air. It then passes through impeller 10 and enters cylinder 11, removing moisture from the clothing. The air then passes through filter 12 and flows to evaporator 4. After cooling and condensing in evaporator 4, it flows to the adsorption zone of dehumidification disc 5. After being dehumidified in the adsorption zone of dehumidification disc 5, it flows back to condenser 2 to be heated, and the cycle repeats. When the ambient temperature is relatively low, the heat pump system and the moisture absorption and dehumidification system of the drying system can be controlled to operate simultaneously to increase the drying speed of the clothing processing apparatus.
[0052] When the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to perform dehumidification, thereby avoiding the heat pump system from shutting down under high temperature conditions and affecting the drying speed of the clothing processing equipment.
[0053] Regarding the filter 12 arranged at the front end of the air flow of the evaporator 4, when the air flow enters the cylinder 11 and takes away the moisture on the clothes, it also takes away the lint on the clothes. The filter 12 has the function of filtering the lint in the air to prevent a large amount of lint from being adsorbed on the surface of the evaporator 4 and affecting the heat exchange between the evaporator 4 and the air.
[0054] The drying system provided in this embodiment can not only dehumidify the air passing through the cylinder 11 through the evaporator 4, but also perform secondary dehumidification on the air passing through the cylinder 11 through the adsorption area of the dehumidification turntable 5, so as to reduce the moisture in the air when flowing to the condenser 2, so that the air can take away more moisture on the clothes after being heated by the condenser 2 and enter the cylinder 11, thereby improving the drying speed of the clothing processing equipment in a low-temperature environment; when the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to work, and the moisture absorption and dehumidification system can work to perform dehumidification, thereby avoiding the situation where the heat pump system stops under high temperature conditions, affecting the drying speed of the clothing processing equipment.
[0055] For rotary dehumidification units, see Figure 2In one embodiment, the rotary dehumidification device further includes a cooler 8 and a second fan 9. A first heat exchange air duct 801 and a second heat exchange air duct 802 are formed in the cooler 8. Driven by the first fan 7, the air passing through the regeneration zone flows to the first fan 7 through the first heat exchange air duct 801. The second fan 9 is used to drive the air outside the clothing processing device to flow to the second heat exchange air duct 802 to dehumidify the air passing through the regeneration zone.
[0056] In this embodiment, the first fan 7 can be arranged between the heater 6 and the cooler 8, or the first fan 7 can also be arranged between the cooler 8 and the regeneration area of the dehumidification rotary disk 5, see Figure 2 , which shows that the first fan 7 is arranged between the heater 6 and the cooler 8. At this time, when the first fan 7 is working, the flow direction of the circulating air is as follows: the medium-temperature and low-humidity gas after passing through the cooler 8 flows to the heater 6 through the first fan 7. The heater 6 heats the air passing through it into high-temperature dry air, and then enters the regeneration area of the dehumidification turntable 5, takes away the moisture in the regeneration area, and flows to the cooler 8 to condense liquid water into medium-temperature and low-humidity gas to continue circulating. Among them, the liquid water condensed in the cooler 8 falls into the water collector.
[0057] For cooler 8, see Figure 3 A first heat exchange duct 801 and a second heat exchange duct 802 are formed in the cooler 8. The first heat exchange duct 801 is not connected to the second heat exchange duct 802. The air passing through the regeneration zone flows to the first fan 7 through the first heat exchange duct 801. The second fan 9 drives the air outside the clothing processing device to flow to the second heat exchange duct 802. The air flowing in the second heat exchange duct 802 exchanges heat with the air flowing in the first heat exchange duct 801, that is, the air flowing in the second heat exchange duct 802 absorbs the heat of the air flowing in the first heat exchange duct 801, so as to realize condensation and dehumidification of the air passing through the regeneration zone of the dehumidification turntable 5.
[0058] Regarding the specific structure of the cooler 8, in one example, see Figure 3 The communication direction of the first heat exchange air duct 801 is along Figure 3 In the X direction, along Figure 3 A plurality of first heat exchange air ducts 801 are arranged at intervals in the direction of the middle Y axis; the communication direction of the second heat exchange air duct 802 is along Figure 3 In the Z direction, along Figure 3 Multiple second heat exchange ducts 802 are spaced apart along the Y-axis. The first heat exchange duct 801 is disconnected from the second heat exchange duct 802. Cooler 8 is made of a heat-conducting material. Driven by the first fan 7, air passing through the regeneration zone is diverted through each of the first heat exchange ducts 801. Driven by the second fan 9, air outside the clothing processing apparatus is diverted through each of the second heat exchange ducts 802.
[0059] In this embodiment, when the second fan 9 is working, the second fan 9 can drive the air outside the clothing processing device to flow to the second heat exchange duct 802, and after passing through the second heat exchange duct 802, the air is discharged outside the clothing processing device through the space inside the clothing processing device. For example, in a specific example, the rotary dehumidification device includes a first air intake duct and a first exhaust duct, the first air intake duct is coordinated with the air intake side of the second heat exchange duct 802 of the cooler 8, and the first exhaust duct is coordinated with the air outlet side of the second heat exchange duct 802 of the cooler 8. The second fan 9 is located on the first air intake duct or the first exhaust duct. Under the drive of the first fan 7, the air outside the clothing processing device is driven to flow through the first air intake duct to the second heat exchange duct 802 of the cooler 8, and is discharged outside the clothing processing device through the first exhaust duct.
[0060] Specifically, the first air intake duct and the first exhaust duct are formed in the clothes processing device, the duct inlet of the first air intake duct is formed on the housing of the clothes processing device, and the duct outlet of the first exhaust duct is formed on the housing of the clothes processing device.
[0061] Typically, the housing of a laundry processing device includes a front side panel, a rear side panel, a left side panel, a right side panel, a top panel, and a bottom panel. The top panel and the bottom panel are disposed vertically relative to each other along the height direction of the laundry processing device, the front side panel and the rear side panel are disposed relative to each other along the front-to-back direction of the laundry processing device, and the left side panel and the right side panel are disposed relative to each other along the left-to-right direction of the laundry processing device. Preferably, the air duct inlet of the first air intake duct is formed on the bottom panel, and the air duct outlet of the first exhaust duct is formed on the rear side panel.
[0062] In this embodiment, by providing a cooler 8, the air passing through the regeneration zone can be dehumidified, so that the air can better dehumidify the regeneration zone of the dehumidification turntable 5 after passing through the heater 6; in addition, in this embodiment, by utilizing the second heat exchange duct 802 of the air outside the clothing processing equipment to flow to the cooler 8 to exchange heat and dehumidify with the air passing through the regeneration zone, that is, using the air outside the clothing processing equipment as the heat exchange medium, the cost of dehumidifying the regeneration zone can be reduced.
[0063] A clothing processing device includes an equipment body and a drying system of the clothing processing device provided by any of the above embodiments; the equipment body includes a partition structure, and the partition structure divides the internal space of the equipment body into a drum placement space and a bottom space along the height direction of the equipment body. The drying system is located in the bottom space, and the drum 11 of the equipment body is located in the drum placement space.
[0064] The heat pump system includes a compressor 1, a condenser 2, a throttling element 3 and an evaporator 4 connected in sequence, and the compressor 1, the condenser 2, the throttling element 3 and the evaporator 4 are all located in the bottom space; the dehumidification system includes a dehumidification turntable 5 and a turntable dehumidification device, and the dehumidification turntable 5 and the turntable dehumidification device are located in the bottom space.
[0065] The clothing processing device provided in this embodiment can not only dehumidify the air passing through the drum 11 through the evaporator, but also perform secondary dehumidification on the air passing through the drum 11 through the adsorption area of the dehumidification turntable, so as to reduce the moisture in the air when flowing to the condenser 2, so that the air can enter the drum 11 after being heated by the condenser 2 and can take away more moisture from the clothes, thereby improving the drying speed of the clothing processing device.
[0066] The rotary dehumidification device includes a first air inlet duct and a first exhaust duct. The first air inlet duct is coordinated with the air inlet side of the second heat exchange duct 802 of the cooler 8, and the first exhaust duct is coordinated with the air outlet side of the second heat exchange duct 802 of the cooler 8. The second fan 9 is located on the first air inlet duct or the first exhaust duct. Driven by the first fan 7, the air outside the clothing processing device is driven to flow through the first air inlet duct to the second heat exchange duct 802 of the cooler 8, and is discharged through the first exhaust duct to drive the clothing processing device. In one embodiment, the first air inlet duct is formed in the bottom space, the first exhaust duct is formed in the bottom space, or the first exhaust duct is formed in the bottom space and the cylinder placement space.

Driven by the second fan 9, the air outside the equipment body can flow to the cooler 8 through the air inlet, and after passing through the cooler 8, it is discharged to the cylinder placement space through the air outlet.
[0071] In this embodiment, the dehumidification system includes a cooler 8 and a second fan 9. A first heat exchange duct 801 and a second heat exchange duct 802 are formed within the cooler 8. Driven by the second fan 9, air from outside the device body flows through the air inlet into the second heat exchange duct 802 of the cooler 8. After being discharged from the second heat exchange duct 802, it is discharged into the cylindrical housing space through the air outlet on the partition structure. Typically, heat dissipation holes are provided on the rear side panels of the device body. Air entering the cylindrical housing space is discharged out of the device body through the heat dissipation holes. The air inlet and the air duct between the air inlet and the air inlet side of the second heat exchange duct 802 of the cooler 8 are referred to as the first air inlet duct. The air inlet is the air duct inlet of the first air inlet duct, which is formed in the bottom space. The air duct between the air outlet side of the second heat exchange duct 802 of the cooler 8 and the heat dissipation holes, as well as the heat dissipation holes, are referred to as the first exhaust duct. The heat dissipation holes are the air duct outlets of the first exhaust duct, i.e., the first exhaust duct is formed in the bottom space and the cylindrical housing space. Of course, in addition to discharging the airflow from the cylinder placement space through the heat dissipation holes, an air duct outlet connected to the cylinder placement space can also be additionally provided on the shell of the device body to discharge the airflow from the cylinder placement space.
[0072] In this embodiment, an air inlet connected to the bottom space is provided on the device body, and an air outlet is provided on the partition structure, so that the air outside the clothing processing device can flow to the second heat exchange duct 802 of the cooler 8 and perform heat exchange and dehumidification with the air in the regeneration zone.
[0073] Based on the example of an air duct inlet connected to the bottom space provided on the device body and an air outlet provided on the partition structure, in one embodiment, the second fan 9 is located below the cooler 8 of the rotary dehumidifier, or, in one embodiment, the second fan 9 is located above the cooler 8 of the rotary dehumidifier, and the second fan 9 is located in the bottom space and supported on the partition structure, the air outlet side of the second fan 9 is directly opposite the air outlet, and the bottom plate of the device body is provided below the cooler 8, and the air inlet is provided on the bottom plate.

In this embodiment, the position of the second fan 9 relative to the cooler 8 is arranged to form a first air intake duct and a first exhaust duct.
[0074] In one embodiment, the clothing processing equipment also includes a control device, and the heat pump system and the moisture absorption and dehumidification system are both connected to the control device. The control device can control the heat pump system to work alone, can control the moisture absorption and dehumidification system to work alone, and can control the heat pump system and the moisture absorption and dehumidification system to work simultaneously.
[0075] That is, the laundry treatment device provided in this embodiment has three operating modes: a heat pump system-only dehumidification mode, a moisture absorption and dehumidification system-only dehumidification mode, and a heat pump and rotor simultaneous dehumidification mode. The heat pump system-only dehumidification mode operates only the heat pump system; the moisture absorption and dehumidification system-only dehumidification mode operates only the moisture absorption and dehumidification system; and the heat pump and rotor simultaneous dehumidification mode operates simultaneously.
[0076] Specifically, when a single hygroscopic dehumidification system dehumidification mode is adopted, when the humid air passes through the adsorption area of the dehumidification turntable 5, the adsorption area can adsorb moisture in the air to achieve the dehumidification effect; in addition, as mentioned above, when the regeneration area of the dehumidification turntable 5 is regenerated and the adsorption area is formed by the rotation of the dehumidification turntable 5, since the adsorption area has heat provided by the turntable dehumidification device at this time, the adsorption area can heat the air passing through it. Therefore, when a single hygroscopic dehumidification system dehumidification mode is adopted, the clothes in the drum can also be dried.
[0077] When the clothing processing device dries wet clothes, one working mode can be operated during the drying process, for example, only the dehumidification mode of the single heat pump system is operated or only the dehumidification mode in which the heat pump and the rotor work simultaneously is operated; or, during the clothing drying process, the dehumidification mode of the single heat pump system, the dehumidification mode in which the heat pump and the rotor work simultaneously, and the dehumidification mode of the single moisture absorption and dehumidification system can be operated respectively in different time periods.
[0078] For example, when the ambient temperature is relatively low, in order to improve the efficiency of the clothing processing equipment in drying clothes, the clothing processing equipment can be controlled to run the dehumidification mode in which the heat pump and the wheel work simultaneously; when the ambient temperature is relatively high, in order to avoid the heat pump system compressor 1 from shutting down due to heavy workload, the clothing processing equipment can be controlled to run the dehumidification mode of a single heat pump system.
[0079] In this embodiment, the clothing processing device can automatically determine the mode to be operated; or / and, three operation keys can be set on the clothing processing device, and the three operation keys correspond to the high-efficiency dehumidification operation key, the medium-efficiency dehumidification operation key and the low-efficiency dehumidification operation key respectively. When the user presses the high-efficiency dehumidification operation key, the clothing processing device runs the dehumidification mode in which the heat pump and the wheel work simultaneously; when the user presses the medium-efficiency dehumidification operation key, the clothing processing device runs the single heat pump system dehumidification mode; when the user presses the low-efficiency dehumidification operation key, the clothing processing device runs the single moisture absorption and dehumidification system dehumidification mode.
[0080] In this embodiment, the clothes treating device is provided with three working modes so that the clothes treating device can operate in different working modes according to different conditions.
[0081] In one embodiment, the clothing processing device also includes a barrel temperature detection sensor, which is connected to the control device. The barrel temperature detection sensor is used to detect the temperature inside the barrel in the clothing processing device. The control device controls the working state of the moisture absorption and dehumidification system according to the signal detected by the barrel temperature detection sensor.
[0082] Specifically, when the clothing processing equipment dries the clothes in the drum, the drum temperature detection sensor detects the temperature in the drum in real time and transmits the detected temperature signal to the control device. When the control device determines that the temperature of the drum is lower than the third preset temperature value, for example, the third preset temperature value is 65°C, the heat pump system and the moisture absorption and dehumidification system are controlled to work at the same time; when the control device determines that the temperature of the drum is not lower than the third preset temperature value, only the heat pump system is controlled to work.
[0083] In this embodiment, by determining the working state of the moisture absorption and dehumidification system according to the temperature inside the drum, it is possible to achieve energy saving while drying clothes quickly.
[0084] In one embodiment, the clothing processing equipment also includes an ambient temperature detection sensor, which is connected to the control device. The ambient temperature detection sensor is used to detect the temperature of the environment. The control device controls the working status of the dehumidification system and the heat pump system according to the signal detected by the ambient temperature detection sensor.
[0085] Specifically, when the clothing processing equipment is drying the clothes in the drum, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing equipment is located in real time, and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is lower than the first preset temperature value, the heat pump system and the moisture absorption and dehumidification system are controlled to work at the same time; when the control device determines that the ambient temperature is not lower than the first preset temperature value, only the heat pump system is controlled to work.
[0086] As mentioned above, when the ambient temperature is relatively low, the drying speed of the clothes dryer is low. In this embodiment, when the ambient temperature is detected to be low, the heat pump system and the moisture absorption and dehumidification system can be controlled to work simultaneously to increase the drying speed of the clothes processing device.
[0087] Specifically, when the clothing processing device dries the clothes in the drum 11, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing device is located in real time, and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is higher than the second preset temperature value, it controls the moisture absorption and dehumidification system to operate.
[0088] When the ambient temperature is relatively high, the heat pump system compressor 1 is subjected to a heavy workload and may shut down. Therefore, when the ambient temperature exceeds a second preset temperature value, the heat pump system can be controlled to shut down, and the dehumidification system can be controlled to operate, thereby performing dehumidification. In this embodiment, when the ambient temperature is relatively high, only the dehumidification system can be controlled to operate, thereby performing dehumidification, thereby avoiding the situation where the heat pump system shuts down under high temperatures.
[0089] In one embodiment, the clothing processing device further includes a timing device connected to the control device, the timing device is used to time the working time of the heat pump system, and the control device controls the working state of the moisture absorption and dehumidification system according to the signal fed back by the timing device.
[0090] For example, in one example, when the heat pump system is in operation, a timing device measures the operating time of the heat pump system. The control device determines, based on a signal transmitted by the timing device, whether the operating time of the heat pump system since startup is less than t1. If so, the dehumidification system is controlled to operate. If not, the dehumidification system is controlled to stop operating. For example, in another example, when the heat pump system is in operation, the control device determines, based on a signal transmitted by the timing device, whether the operating time of the heat pump system until the end of operation is less than t2. If so, the dehumidification system is controlled to operate. If not, the dehumidification system is controlled to stop operating.
[0091] In the prior art, when using a heat pump dryer to dry clothes, the heat pump system's energy efficiency is relatively low upon startup, resulting in low drying efficiency. In this embodiment, during the heat pump system startup and operation time t1, the heat pump system and the moisture absorption and dehumidification system are controlled to operate simultaneously, thereby improving the dryer's drying efficiency.
[0092] In the prior art, when using a heat pump dryer to dry clothes, the moisture content of the clothes decreases during the final drying phase, and the amount of moisture removed from the clothes by air entering the dryer decreases. This reduces the amount of heat absorbed by the air by evaporator 4, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is about to end operation at t2, the heat pump system and the moisture absorption and dehumidification system are controlled to operate simultaneously, thereby improving the drying efficiency of the dryer.
[0093] In this embodiment, the working state of the moisture absorption and dehumidification system is controlled according to the working time of the heat pump system, so as to achieve the control of the moisture absorption and dehumidification system when the energy efficiency of the heat pump system is low, which is beneficial to improving the drying efficiency of the dryer.
[0094] A method for drying clothes using the drying system of the clothes processing device provided in any of the above embodiments comprises the following steps:
[0095] Determine whether the conditions for the heat pump system and the moisture absorption and dehumidification system to operate simultaneously are met;
[0096] If so, the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously;
[0097] If not, the moisture absorption and dehumidification system is controlled to stop working.
[0098] As mentioned above, the heat pump system includes a compressor 1, a condenser 2, a throttling element 3, and an evaporator 4, which are connected in sequence. The dehumidification system includes a dehumidification rotary disk 5 and a rotary disk dehumidification device. The dehumidification rotary disk 5 is formed with an adsorption zone and a regeneration zone. The rotary disk dehumidification device includes a heater 6 and a first fan 7. The dehumidification rotary disk 5 is disposed between the evaporator 4 and the condenser 2. The airflow passing through the evaporator 4 can flow to the condenser 2 through the adsorption zone. Under the action of the first fan 7, the air can flow to the regeneration zone through the heater 6. Because the heat pump system has a better effect of drying clothes than the dehumidification system, the heat pump system can be used primarily when drying clothes. However, under certain conditions, such as when the energy efficiency of the heat pump system is relatively low, the heat pump system and the dehumidification system can be controlled to operate simultaneously to improve the efficiency of the clothing processing equipment in drying clothes.
[0099] In one embodiment, when the heat pump system is in operation, it is determined whether the temperature of the drum in the clothing processing device is higher than a preset temperature. If so, the moisture absorption and dehumidification system is controlled to stop working; if not, the moisture absorption and dehumidification system is controlled to work.
[0100] Specifically, when the clothing processing equipment dries the clothes in the drum, the drum temperature detection sensor detects the temperature in the drum in real time and transmits the detected temperature signal to the control device. When the control device determines that the temperature of the drum is lower than the third preset temperature value, for example, the third preset temperature value is 65°C, the heat pump system and the moisture absorption and dehumidification system are controlled to work at the same time; when the control device determines that the temperature of the drum is not lower than the third preset temperature value, only the heat pump system is controlled to work, and the moisture absorption and dehumidification system is controlled to stop working.
[0101] In this embodiment, by determining the working state of the moisture absorption and dehumidification system according to the temperature inside the drum, it is possible to achieve energy saving while drying clothes quickly.
[0102] In one embodiment, when the heat pump system is in operation: it is determined whether the operating time of the heat pump system from startup is less than t1; if it is less than t1, the moisture absorption and dehumidification system is controlled to operate; if it is not less than t1, the moisture absorption and dehumidification system is controlled to stop operating; it is determined whether the time from the end of the operation of the heat pump system is less than t2; if it is less than t2, the moisture absorption and dehumidification system is controlled to operate; if it is not less than t2, the moisture absorption and dehumidification system is controlled to stop operating.
[0103] In the prior art, when using a heat pump dryer to dry clothes, the heat pump system's energy efficiency is relatively low upon startup, resulting in low drying efficiency. In this embodiment, during the heat pump system startup and operation time t1, the heat pump system and the moisture absorption and dehumidification system are controlled to operate simultaneously, thereby improving the dryer's drying efficiency.
[0104] In the prior art, when using a heat pump dryer to dry clothes, the moisture content of the clothes decreases during the final drying phase, and the amount of moisture removed from the clothes by air entering the dryer decreases. This reduces the amount of heat absorbed by the air by evaporator 4, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is about to end operation at t2, the heat pump system and the moisture absorption and dehumidification system are controlled to operate simultaneously, thereby improving the drying efficiency of the dryer.
[0105] Regarding the time t1 and t2, for example, t1 is 2 to 5 minutes, and t2 is 2 to 5 minutes.
[0106] In this embodiment, the working state of the moisture absorption and dehumidification system is controlled according to the working time of the heat pump system, so as to achieve the control of the moisture absorption and dehumidification system when the energy efficiency of the heat pump system is low, which is beneficial to improving the drying efficiency of the dryer.
[0107] In one embodiment, when the heat pump system is in operation, it is determined whether the ambient temperature is lower than a first preset temperature value. If so, the moisture absorption and dehumidification system is controlled to operate; if not, the moisture absorption and dehumidification system is controlled to stop operating.
[0108] Specifically, when the clothing processing equipment is drying the clothes in the drum, the ambient temperature detection sensor detects the temperature of the environment in which the clothing processing equipment is located in real time, and transmits the detected temperature signal to the control device. When the control device determines that the ambient temperature is lower than the first preset temperature value, the heat pump system and the moisture absorption and dehumidification system are controlled to work at the same time; when the control device determines that the ambient temperature is not lower than the first preset temperature value, only the heat pump system is controlled to work.
[0109] In this embodiment, when it is detected that the ambient temperature is low, the heat pump system and the moisture absorption and dehumidification system can be controlled to work simultaneously, so as to increase the speed at which the clothes processing device dries clothes.
[0110] In one embodiment, it is determined whether the ambient temperature is higher than a second preset temperature value. If so, the heat pump system is controlled to stop working and the moisture absorption and dehumidification system is controlled to work; if not, the heat pump system is controlled to work.
[0111] When the ambient temperature is relatively high, the heat pump system compressor 1 has a heavy workload and may shut down; therefore, when the ambient temperature is higher than the second preset temperature value, the heat pump system can be controlled to stop working, and the dehumidification system can be controlled to work, and the dehumidification system can be used to perform dehumidification.
[0112] In this embodiment, when the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to work, and the moisture absorption and dehumidification system works to perform dehumidification, thereby avoiding the shutdown of the heat pump system under high temperature.
[0113] In one embodiment, it is determined whether the conditions for the moisture absorption and dehumidification system to work alone are met; if so, the moisture absorption and dehumidification system is controlled to work alone.
[0114] That is, the method for drying clothes provided in this embodiment also includes using a moisture absorption and dehumidification system alone to dehumidify the clothes, that is, when the conditions for the dehumidification system to work alone are met, such as when the clothing processing device receives an instruction that only the moisture absorption and dehumidification system works, the moisture absorption and dehumidification system can be controlled to work alone.
[0115] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
