[0008] In some implementations, the rotary dehumidifier also includes a cooler and a second fan. The cooler has a first heat exchange duct and a second heat exchange duct. Driven by the first fan, the air passing through the regeneration zone flows to the first fan through the first heat exchange duct. The second fan drives the air outside the clothing processing equipment to flow to the second heat exchange duct for dehumidifying the air passing through the regeneration zone.

[0012] In some implementations, when the dehumidification system of the drying system includes a cooler and a second fan, the main body of the equipment is provided with an air inlet that communicates with the bottom space, and the partition structure is provided with an air outlet. Driven by the second fan, the air outside the main body of the equipment can flow to the cooler through the air inlet, and after passing through the cooler, it is discharged to the cylinder placement space through the air outlet.
[0013] In some implementations, the second fan is located above the cooler of the rotary dehumidifier. The second fan is supported on the partition structure and located in the bottom space. The air outlet side of the second fan faces the air inlet. The bottom plate of the main body of the equipment is provided below the cooler, and the air inlet is provided on the bottom plate.
[0014] In some implementations, the garment processing equipment also includes a control device, to which the heat pump system and the moisture absorption and dehumidification system are connected. The control device can control the heat pump system to work alone, control the moisture absorption and dehumidification system to work alone, and control the heat pump system and the moisture absorption and dehumidification system to work simultaneously.
[0015] In some implementations, the garment processing equipment also includes a drum temperature detection sensor connected to a control device. The drum temperature detection sensor is used to detect the temperature inside the drum of the garment processing equipment, and the control device controls the working state of the moisture absorption and dehumidification system based on the signal detected by the drum temperature detection sensor.
[0016] In some implementations, the garment processing equipment also includes an ambient temperature sensor connected to a control device.

[0017] In some implementations, the garment processing equipment also includes a timing device connected to a control device. The timing device is used to time the working time of the heat pump system, and the control device controls the working status of the moisture absorption and dehumidification system based on the signal fed back by the timing device.
[0018] A method for drying clothes using a drying system provided by any of the above technical solutions includes the following:
[0019] Determine whether the conditions for simultaneous operation of the heat pump system and the moisture absorption and dehumidification system are met;
[0020] If so, then control the heat pump system and the dehumidification system to work simultaneously;
[0021] If not, the dehumidification system will stop working.
[0022] In some implementations, when the heat pump system is in operation: it is determined whether the temperature of the drum in the clothing processing equipment is higher than a third preset temperature value. If so, the moisture absorption and dehumidification system is controlled to stop working; otherwise, the moisture absorption and dehumidification system is controlled to work.
[0023] In some implementations, when the heat pump system is in operation: it is determined whether the running time of the heat pump system since startup is less than t1. If it is less than t1, the dehumidification system is controlled to work. If it is not less than t1, the dehumidification system is controlled to stop working.
[0024] Determine if the time remaining before the end of operation of the heat pump system is less than t2. If it is less than t2, control the dehumidification system to work. If it is not less than t2, control the dehumidification system to stop working.
[0025] In some implementations, when the heat pump system is in operation: it determines whether the ambient temperature is lower than a first preset temperature value; if so, it controls the dehumidification system to operate; if not, it controls the dehumidification system to stop operating.
[0026] In some implementations, if the ambient temperature is higher than a second preset temperature value, the heat pump system is controlled to stop working, and the dehumidification system is controlled to work; otherwise, the heat pump system is controlled to work.
[0027] In some implementations, it is determined whether the conditions for the dehumidification system to operate independently are met; if they are met, the dehumidification system is controlled to operate independently.
[0028] The beneficial effects of this application are as follows: When the heat pump system and the dehumidification system are working simultaneously, the drying system provided in this embodiment can not only dehumidify the air passing through the drum through the evaporator, but also perform secondary dehumidification of the air passing through the drum through the adsorption zone of the dehumidification disc. This reduces the moisture in the air flowing towards the condenser, making it easier for the air to be heated by the condenser and then enter the drum to remove more moisture from the clothes, thereby improving the drying speed of the clothing processing equipment in low-temperature environments. In addition, when the ambient temperature is relatively high, only the dehumidification system can be controlled to work, and dehumidification can be performed by the dehumidification system, avoiding the shutdown of the heat pump system under high-temperature conditions, which would affect the drying speed of the clothing processing equipment.

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be further described in detail below with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

Those skilled in the art will understand that the terms "first" and "second" do not limit the quantity or execution order, and that the terms "first" and "second" do not necessarily imply that they are different.
[0038] In this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0039] In this application, "and / or" is merely a way of describing the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone.

[0040] It should be noted that, in this application, the words "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 more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.
[0041] Please see Figure 1 This is a diagram of an existing heat pump dryer system. The heat pump system operates as follows: High-temperature, high-pressure gaseous refrigerant releases heat in condenser 2, becoming high-pressure, medium-temperature liquid refrigerant. It then passes through throttling element 3, where it is cooled and depressurized into low-temperature, low-pressure two-phase gas-liquid refrigerant. Entering evaporator 4, it absorbs heat and vaporizes into medium-temperature, low-pressure gaseous refrigerant, which is then compressed by compressor 1 into high-temperature, high-pressure gaseous refrigerant. The airflow within the dryer is as follows: After passing through condenser 2, the air is heated to high-temperature dry air. It then passes through impeller 10 into drum 11, carrying away moisture from the clothes. After being cooled and condensed into water in evaporator 4, the water flows back to condenser 2 for reheating, and the cycle repeats continuously. The liquid water condensed on the surface of evaporator 4 falls into a water collector below evaporator 4.
[0042] When the ambient temperature is low, the evaporation temperature of the heat pump system decreases. Evaporation temperature refers to the boiling point of the refrigerant in the evaporator. A decrease in evaporation temperature leads to a drop in the suction pressure of compressor 1, resulting in a decrease in the heating capacity of the heat pump system. This, in turn, affects the removal of moisture from clothes by the circulating air as it passes through the drum 11. Therefore, the drying speed of the dryer is slow in low-temperature environments. Conversely, when the ambient temperature is high, the compressor 1 of the heat pump system operates under heavy load and may shut down, causing a slow drying speed.
[0043] To address the above issues, this embodiment provides a drying system for a garment processing device. The garment processing device can be a dryer or a washer-dryer combo. The garment processing device includes a heat pump system and a moisture absorption and dehumidification system.
[0044] Please 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 and medium-temperature liquid refrigerant. It is then cooled and depressurized by the throttling element 3 to become a low-temperature and low-pressure gas-liquid two-phase refrigerant. After absorbing heat in the evaporator 4, it enters the compressor 1 and is compressed into a high-temperature and high-pressure gaseous refrigerant.
[0045] The moisture absorption and dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. Please refer to [link / reference]. Figure 2 The diagram shows the dehumidification turntable 5, which is located between the evaporator 4 and the condenser 2. The dehumidification turntable 5 is used to dehumidify the air passing through it.
[0046] Specifically, the dehumidifying disc 5 has an adsorption zone and a regeneration zone. When humid air passes through the adsorption zone of the dehumidifying disc 5, the moisture-absorbing material on the disc adsorbs the moisture. The regeneration zone is exposed to hot air, meaning that hot air generated by the dehumidifying device blows onto the regeneration zone, causing the moisture on the moisture-absorbing material to evaporate. The process of the dehumidifying disc 5 adsorbing moisture is called adsorption, and the process of moisture evaporation is called regeneration. After regeneration, the regeneration zone of the dehumidifying disc 5 rotates to form an adsorption zone, allowing it to continuously adsorb moisture from the air passing through. Furthermore, when the regeneration zone of the dehumidifying disc 5 rotates to form an adsorption zone, the adsorption zone receives heat from the dehumidifying device, thus heating the air passing through it.
[0047] Regarding the moisture-absorbing material of the dehumidifying turntable 5, preferably, the moisture-absorbing material on the dehumidifying turntable 5 is a molecular sieve.
[0048] In this embodiment, the adsorption zone of the dehumidification disc 5 is located 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. That is, after the air is dehumidified by the evaporator 4, it can be dehumidified again through the adsorption zone of the dehumidification disc 5.
[0049] In this embodiment, the rotary dehumidifier 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. Please refer to [link to documentation]. Figure 2 The diagram shows heater 6 and first fan 7.
[0050] Heater 6 is used to heat the airflow passing through it. Heater 6 can be an electric heating tube. When the first fan 7 is working, it blows the airflow toward heater 6. 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 dehumidification disc 5, it can remove the moisture in the regeneration zone.
[0051] When the drying system provided in this embodiment is applied to a clothing processing device and the heat pump system and the moisture absorption and dehumidification system operate simultaneously, please refer to [link to relevant documentation]. Figure 2 The airflow direction within the garment processing equipment is as follows: After passing through the condenser 2, the circulating air is heated into high-temperature dry air. It then enters the drum 11 through the impeller 10, carrying away moisture from the clothes. After passing through the filter 12, the air flows to the evaporator 4. After being cooled and condensed into water in the evaporator 4, the air flows to the adsorption zone of the dehumidification disc 5. After being dehumidified in the adsorption zone of the dehumidification disc 5, it flows back to the condenser 2 for heating, and the cycle repeats continuously. When the ambient temperature is relatively low, the heat pump system and the dehumidification system of the drying system can be controlled to work simultaneously to increase the drying speed of the garment processing equipment.
[0052] When the ambient temperature is high, only the moisture absorption and dehumidification system can be controlled to operate, and dehumidification can be carried out by the moisture absorption and dehumidification system to avoid the heat pump system from shutting down under high temperature conditions, which would affect the drying speed of the clothing processing equipment.
[0053] Regarding the filter screen 12 installed at the front end of the airflow of the evaporator 4, the airflow entering the cylinder 11 carries away the moisture on the clothes and also carries away the lint on the clothes. The filter screen 12 has the function of filtering the lint in the air to prevent a large amount of lint from adhering to 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 drum 11 through the evaporator 4, but also perform secondary dehumidification of the air passing through the drum 11 through the adsorption zone of the dehumidification turntable 5. This reduces the moisture in the air flowing towards the condenser 2, making it easier for the air to carry away more moisture from the clothes after being heated by the condenser 2 and entering the drum 11. This can improve the drying speed of the clothing processing equipment in low-temperature environments. When the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to work, and dehumidification can be carried out by the moisture absorption and dehumidification system. This avoids the heat pump system from shutting down under high-temperature conditions, which would affect the drying speed of the clothing processing equipment.
[0055] For information on rotary dehumidifiers, please refer to [link / reference]. Figure 2In one embodiment, the rotary dehumidifier further includes a cooler 8 and a second fan 9. The cooler 8 has a first heat exchange duct 801 and a second heat exchange duct 802. Driven by the first fan 7, the air passing through the regeneration zone flows to the first fan 7 through the first heat exchange duct 801. The second fan 9 is used to drive the air outside the clothing processing equipment to flow to the second heat exchange duct 802 for dehumidifying the air passing through the regeneration zone.
[0056] In this embodiment, the first fan 7 can be disposed between the heater 6 and the cooler 8, or the first fan 7 can also be disposed between the cooler 8 and the regeneration zone of the dehumidification disc 5. Please refer to [link to relevant documentation]. Figure 2 The diagram shows that the first fan 7 is located between the heater 6 and the cooler 8. 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 zone of the dehumidification disc 5, which carries away the moisture in the regeneration zone. The air then flows to the cooler 8 to condense into liquid water and becomes medium-temperature and low-humidity gas to continue circulating. The liquid water condensed in the cooler 8 falls into the water collector.
[0057] For information about cooler 8, please refer to [link / reference]. Figure 3 The cooler 8 has a first heat exchange duct 801 and a second heat exchange duct 802. The first heat exchange duct 801 and the second heat exchange duct 802 are not connected. The air passing through the regeneration zone flows through the first heat exchange duct 801 to the first fan 7. The second fan 9 drives the air outside the clothing processing equipment 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 the condensation and dehumidification of the air passing through the regeneration zone of the dehumidification turntable 5.
[0058] For a specific example of the structure of cooler 8, please refer to [link / reference]. Figure 3 The direction of connection of the first heat exchange duct 801 is along Figure 3 The direction of X, along Figure 3 Multiple first heat exchange ducts 801 are spaced apart along the Y-axis; the connecting direction of the second heat exchange duct 802 is along... Figure 3 In the direction of Z, along Figure 3 Multiple second heat exchange ducts 802 are spaced apart along the Y-axis, and the first heat exchange duct 801 is not connected to the second heat exchange duct 802. The cooler 8 is made of heat transfer material. Driven by the first fan 7, the air passing through the regeneration zone is diverted through each of the first heat exchange ducts 801, and under the action of the second fan 9, the air outside the clothing processing equipment 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 equipment to flow to the second heat exchange duct 802. After passing through the second heat exchange duct 802, the air is discharged outside the clothing processing equipment through the space inside the clothing processing equipment. For example, in a specific example, the rotary dehumidifier includes a first air inlet duct and a first exhaust duct. The first air inlet duct is connected to the air inlet side of the second heat exchange duct 802 of the cooler 8, and the first exhaust duct is connected to 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 9, the air outside the clothing processing equipment is driven to flow through the first air inlet duct to the second heat exchange duct 802 of the cooler 8, and then discharged outside the clothing processing equipment through the first exhaust duct.
[0060] Specifically, the first air intake duct and the first air exhaust duct are formed inside the garment processing equipment. The air inlet of the first air intake duct is formed on the housing of the garment processing equipment, and the air outlet of the first air exhaust duct is formed on the housing of the garment processing equipment.
[0061] Typically, the housing of a garment processing device includes a front panel, a rear panel, a left panel, a right panel, a top panel, and a bottom panel. The top and bottom panels are arranged vertically opposite each other along the height of the garment processing device, the front and rear panels are arranged vertically opposite each other along the front-rear direction of the garment processing device, and the left and right panels are arranged horizontally opposite each other along the left-right direction of the garment processing device. Preferably, the air inlet of the first air intake duct is formed on the bottom panel, and the air outlet of the first exhaust duct is formed on the rear panel.
[0062] In this embodiment, by setting up 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 using the air outside the clothing processing equipment to flow to the second heat exchange duct 802 of the cooler 8 to exchange heat and dehumidify with the air passing through the regeneration zone, that is, by 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 garment processing device includes a main body and a drying system for the garment processing device provided in any of the above embodiments; the main body includes a partition structure, which divides the internal space of the main body into a drum placement space and a bottom space along the height direction of the main body, the drying system is located in the bottom space, and the drum 11 of the main 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. The compressor 1, condenser 2, throttling element 3, and evaporator 4 are all located in the bottom space. The dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. The dehumidification disc 5 and the disc dehumidification device are located in the bottom space.
[0065] The clothing processing equipment provided in this embodiment can not only dehumidify the air passing through the drum 11 through the evaporator, but also perform secondary dehumidification of the air passing through the drum 11 through the adsorption zone of the dehumidification turntable, so as to reduce the moisture in the air flowing to the condenser 2. This makes it easier for the air to enter the drum 11 after being heated by the condenser 2, so as to remove more moisture from the clothes and improve the drying speed of the clothing processing equipment.
[0066] The rotary dehumidifier includes a first air intake duct and a first exhaust duct. The first air intake duct is connected to the air inlet side of the second heat exchange duct 802 of the cooler 8, and the first exhaust duct is connected to 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. Driven by the first fan 9, the air outside the clothing processing equipment 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 equipment through the first exhaust duct. In one embodiment, the first air intake 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.
[0067] The first air intake duct can be formed in the bottom space. The air inlet of the first air intake duct is set on the shell of the main body of the equipment, and the air inlet of the first air intake duct is connected to the bottom space.
[0068] When the first exhaust duct is formed in the bottom space, the outlet of the first exhaust duct is located on the shell of the main body of the equipment, and the outlet of the first exhaust duct is connected to the bottom space; when the first exhaust duct is formed in both the bottom space and the cylinder placement space, the outlet of the first exhaust duct is located on the shell of the main body of the equipment, and the outlet of the first exhaust duct is connected to the cylinder placement space.
[0069] This embodiment provides two methods for the first exhaust duct, so as to select the appropriate method according to the internal layout of the garment processing equipment.
[0070] In one embodiment, when the dehumidification system of the drying system includes a cooler 8 and a second fan 9, the main body of the equipment is provided with an air inlet that communicates with the bottom space, and the partition structure is provided with an air outlet. Driven by the second fan 9, the air outside the main body of the equipment 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. The cooler 8 contains a first heat exchange duct 801 and a second heat exchange duct 802. Driven by the second fan 9, air from outside the main body of the equipment flows through the air inlet to 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 cylinder placement space through the air outlet on the partition structure. Typically, heat dissipation holes are provided on the rear side plate of the main body of the equipment, and the airflow entering the cylinder placement space is discharged outside the main body of the equipment through these holes. The air inlet and the duct between the air inlet and the air inlet side of the second heat exchange duct 802 of the cooler 8 are called the first air intake duct. The air inlet is the inlet of the first air intake duct, which is formed in the bottom space. The 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 called the first exhaust duct. The heat dissipation holes are the outlet of the first exhaust duct, meaning the first exhaust duct is formed in both the bottom space and the cylinder placement space. Of course, in addition to exhausting the airflow from the cylinder placement space through the heat dissipation holes, an additional air duct outlet connected to the cylinder placement space can be added to the main body of the equipment to exhaust the airflow from the cylinder placement space.
[0072] In this embodiment, an air inlet connected to the bottom space is provided on the main body of the equipment, and an air outlet is provided on the partition structure, so that the air outside the clothing processing equipment can flow to the second heat exchange duct 802 of the cooler 8 to exchange heat and dehumidify with the air in the regeneration zone.
[0073] In an example where the main body of the equipment has an air duct inlet connected to the bottom space and an air outlet is provided on the partition structure, in one embodiment, the second fan 9 is located below the cooler 8 of the rotary dehumidifier; or, in another 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 faces the air outlet. A bottom plate of the main body of the equipment is provided below the cooler 8, and an air inlet is provided on the bottom plate. Driven by the second fan 9, air from outside the main body of the equipment flows through the air inlet to the second heat exchange duct 802 of the cooler 8, and after being discharged from the second heat exchange duct 802, flows through the second fan 9 to the air outlet on the partition structure, and is discharged into the cylinder placement space through the air outlet. In this embodiment, the arrangement of the position of the second fan 9 relative to the cooler 8 facilitates the formation of a first air inlet duct and a first air outlet duct.
[0074] In one embodiment, the garment processing equipment further 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, control the moisture absorption and dehumidification system to work alone, and control the heat pump system and the moisture absorption and dehumidification system to work simultaneously.
[0075] The clothing processing equipment provided in this embodiment has three operating modes: a single heat pump system dehumidification mode, a single moisture absorption and dehumidification system dehumidification mode, and a simultaneous heat pump and dehumidification wheel dehumidification mode. The single heat pump system dehumidification mode means only the heat pump system operates; the single moisture absorption and dehumidification system dehumidification mode means only the moisture absorption and dehumidification system operates; and the simultaneous heat pump and dehumidification wheel dehumidification mode means both the heat pump system and the moisture absorption and dehumidification system are operating simultaneously.
[0076] Specifically, when using the single moisture absorption and dehumidification system in dehumidification mode, when humid air passes through the adsorption zone of the dehumidification disc 5, the adsorption zone can adsorb the moisture in the air, achieving the dehumidification effect. In addition, as mentioned above, when the regeneration zone of the dehumidification disc 5 is regenerated and forms an adsorption zone through the rotation of the dehumidification disc 5, the adsorption zone has the heat provided by the disc dehumidification device, which allows the adsorption zone to heat the air passing through it. Therefore, when using the single moisture absorption and dehumidification system in dehumidification mode, it can also dry the clothes inside the drum.
[0077] When the clothing processing equipment dries wet clothes, it can operate in one working mode during the drying process. For example, it can operate in a single heat pump system dehumidification mode or in a single heat pump and dehumidification mode where the heat pump and dehumidifier work simultaneously. Alternatively, during the drying process, it can operate in a single heat pump system dehumidification mode, a heat pump and dehumidifier working simultaneously dehumidification mode, or a single moisture absorption and dehumidification system dehumidification mode at different time periods.
[0078] For example, when the ambient temperature is low, in order to improve the drying efficiency of the clothing processing equipment, the clothing processing equipment can be controlled to operate in a dehumidification mode where the heat pump and the dehumidifier work simultaneously; when the ambient temperature is 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 operate in a single heat pump system dehumidification mode.
[0079] In this embodiment, the clothing processing device can automatically determine the operating mode; or / and, three operation keys can be set on the clothing processing device, which 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 operates in the dehumidification mode where the heat pump and the dehumidifier work simultaneously; when the user presses the medium-efficiency dehumidification operation key, the clothing processing device operates in the dehumidification mode of a single heat pump system; when the user presses the low-efficiency dehumidification operation key, the clothing processing device operates in the dehumidification mode of a single moisture absorption and dehumidification system.
[0080] In this embodiment, the clothing processing equipment is configured to include three working modes, so that the clothing processing equipment can operate in different working modes according to different conditions.
[0081] In one embodiment, the garment processing equipment further includes a drum temperature detection sensor connected to a control device. The drum temperature detection sensor is used to detect the temperature inside the drum of the garment processing equipment, and the control device controls the working state of the moisture absorption and dehumidification system based on the signal detected by the drum temperature detection sensor.
[0082] Specifically, when the clothes drying 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℃, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the temperature of the drum is not lower than the third preset temperature value, it controls only the heat pump system to work.
[0083] In this embodiment, by setting the working state of the moisture absorption and dehumidification system to be determined based on the temperature inside the drum, it can achieve the effect of quickly drying clothes while saving energy.
[0084] In one embodiment, the garment processing equipment further includes an ambient temperature sensor connected to a control device. The ambient temperature sensor is used to detect the ambient temperature, and the control device controls the operating status of the moisture absorption and dehumidification system and the heat pump system based on the signal detected by the ambient temperature sensor.
[0085] Specifically, when the clothing processing equipment dries 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, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the ambient temperature is not lower than the first preset temperature value, it controls only the heat pump system to work.
[0086] As mentioned earlier, the drying speed of a clothes dryer is low when the ambient temperature is relatively low. In this embodiment, when a low ambient temperature is detected, 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 equipment.
[0087] Specifically, when the clothing processing equipment dries the clothes in the drum 11, 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 higher than the second preset temperature value, it controls the moisture absorption and dehumidification system to work.
[0088] When the ambient temperature is high, the heat pump system compressor 1 will be under heavy load and may shut down. Therefore, when the ambient temperature exceeds a second preset temperature value, the heat pump system can be controlled to stop working, and the dehumidification system can be activated to perform dehumidification. In this embodiment, when the ambient temperature is high, only the dehumidification system can be controlled to work, thus avoiding the heat pump system shutting down at high temperatures.
[0089] In one embodiment, the garment processing equipment further includes a timing device connected to a 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 based on the signal fed back by the timing device.
[0090] For example, in one scenario, when the heat pump system is in operation, a timing device tracks the operating time. The control device determines whether the operating time of the heat pump system since startup is less than t1 based on the signal transmitted by the timing device. If it is less than t1 (t1 can be 2-5 minutes), the control device activates the dehumidification system; otherwise, it stops operating. In another scenario, when the heat pump system is in operation, the control device determines whether the remaining operating time is less than t2 based on the signal transmitted by the timing device. If it is less than t2 (t2 can be 2-5 minutes), the control device activates the dehumidification system; otherwise, it stops operating.
[0091] In existing technologies, when using a heat pump dryer to dry clothes, the energy efficiency of the heat pump system is relatively low when it first starts up, resulting in low drying efficiency. In this embodiment, during the time t1 that the heat pump system starts up and operates, the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.
[0092] In existing technologies, when using a heat pump dryer to dry clothes, the moisture on the clothes decreases in the final stage of drying. As more air enters the drum and carries away the moisture, the evaporator 4 absorbs less heat from the air, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is still t2 away from ending its operation, the heat pump system and the dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.
[0093] In this embodiment, the working state of the dehumidification system is controlled according to the working time of the heat pump system, so as to control the operation of the dehumidification system when the energy efficiency of the heat pump system is low, which helps to improve the drying efficiency of the dryer.
[0094] A method for drying clothes using a drying system of the clothing processing equipment provided in any of the above embodiments includes the following:
[0095] Determine whether the conditions for simultaneous operation of the heat pump system and the moisture absorption and dehumidification system are met;
[0096] If so, then control the heat pump system and the dehumidification system to work simultaneously;
[0097] If not, the dehumidification system will 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 connected in sequence. The dehumidification system includes a dehumidification disc 5 and a disc dehumidification device. The dehumidification disc 5 has an adsorption zone and a regeneration zone. The disc dehumidification device includes a heater 6 and a first fan 7. The dehumidification disc 5 is located between the evaporator 4 and the condenser 2. Airflow through the evaporator 4 can flow to the condenser 2 through the adsorption zone. Under the action of the first fan 7, air can flow to the regeneration zone through the heater 6. Since the heat pump system has a better drying effect on clothes than the dehumidification system, the heat pump system can be mainly used 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 work simultaneously to improve the drying efficiency of the clothes processing equipment.
[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 equipment is higher than the preset temperature. If so, the moisture absorption and dehumidification system is controlled to stop working; otherwise, 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℃, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously. When the control device determines that the temperature of the drum is not lower than the third preset temperature value, it controls only the heat pump system to work and controls the moisture absorption and dehumidification system to stop working.
[0101] In this embodiment, by setting the working state of the moisture absorption and dehumidification system to be determined based on the temperature inside the drum, it can achieve the effect of quickly drying clothes while saving energy.
[0102] In one embodiment, when the heat pump system is in operation: it is determined whether the running time of the heat pump system from startup is less than t1. If it is less than t1, the dehumidification system is controlled to work. If it is not less than t1, the dehumidification system is controlled to stop working. It is also determined whether the time remaining until the end of operation of the heat pump system is less than t2. If it is less than t2, the dehumidification system is controlled to work. If it is not less than t2, the dehumidification system is controlled to stop working.
[0103] In existing technologies, when using a heat pump dryer to dry clothes, the energy efficiency of the heat pump system is relatively low when it first starts up, resulting in low drying efficiency. In this embodiment, during the time t1 that the heat pump system starts up and operates, the heat pump system and the moisture absorption and dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.
[0104] In existing technologies, when using a heat pump dryer to dry clothes, the moisture on the clothes decreases in the final stage of drying. As more air enters the drum and carries away the moisture, the evaporator 4 absorbs less heat from the air, which in turn affects the energy efficiency of the heat pump system. In this embodiment, when the heat pump system is still t2 away from ending its operation, the heat pump system and the dehumidification system are controlled to work simultaneously, which helps to improve the drying efficiency of the dryer.
[0105] Regarding times 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 dehumidification system is controlled according to the working time of the heat pump system, so as to control the operation of the dehumidification system when the energy efficiency of the heat pump system is low, which helps to improve 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 preset temperature value; if so, the dehumidification system is controlled to operate; if not, the dehumidification system is controlled to stop operating.
[0108] Specifically, when the clothing processing equipment dries 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, it controls the heat pump system and the moisture absorption and dehumidification system to work simultaneously; when the control device determines that the ambient temperature is not lower than the first preset temperature value, it controls only the heat pump system to work.
[0109] In this embodiment, when a low ambient temperature is detected, the heat pump system and the moisture absorption and dehumidification system can be controlled to work simultaneously to improve the drying speed of the clothes processing equipment.
[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 dehumidification system is controlled to work; if not, the heat pump system is controlled to work.
[0111] When the ambient temperature is high, the heat pump system compressor 1 will be under heavy load 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 to dehumidify.
[0112] In this embodiment, when the ambient temperature is relatively high, only the moisture absorption and dehumidification system can be controlled to work, and dehumidification can be performed by the moisture absorption and dehumidification system to avoid the heat pump system from shutting down at high temperatures.
[0113] In one embodiment, it is determined whether the conditions for the dehumidification system to operate independently are met; if they are met, the dehumidification system is controlled to operate independently.
[0114] The method for drying clothes provided in this embodiment also includes using a separate moisture absorption and dehumidification system to dehumidify the clothes. That is, when the conditions for the dehumidification system to work alone are met, such as when the clothes processing equipment receives an instruction to only operate the moisture absorption and dehumidification system, it can control the moisture absorption and dehumidification system to work alone.
[0115] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
