Detailed Implementation

[0038] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the drying device of the present invention is described in conjunction with a drum dryer, this is not limiting; other devices with drying requirements can be configured with the drying device of the present invention, such as cabinet-type clothes dryers.

[0039] Secondly, it should be noted that in the description of this invention, terms such as "inner" and "outer" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention.

[0040] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly 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 connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] A drum dryer typically includes a housing, a drying unit housed within the housing, and a power supply unit. The power supply unit provides power to the drying unit, causing the drum inside to rotate and driving the heat pump circulation device within the drying unit to dry the clothes inside the drum.

[0042] The preferred technical solution of the drying device of the present invention will be described below in conjunction with the above-mentioned drum drying equipment.

[0043] First refer to Figure 1 , Figure 2 Figure 3 as well as Figure 4 The clothes drying device of the present invention may include a roller 10 and a heat pump circulation device.

[0044] like Figure 1 As shown, the drum 10 can be a barrel-shaped structure, and the clothes to be dried are placed inside the drum 10. A drive motor 11 is also provided on the drum 10, which drives the drum 10 to rotate, thereby causing the clothes inside the drum 10 to rotate, facilitating even heating and rapid drying of the clothes. In one possible implementation, such as... Figure 1As shown, a belt 12 is fitted over the output shaft of the drive motor 11 and the roller 10. The belt 12 extends perpendicularly to the center line of the output shaft and the roller 10, and the center line of the output shaft is parallel to the center line of the roller 10. The output shaft of the drive motor 11 drives the roller 10 to rotate by rotating the belt 12. Alternatively, the output shaft of the drive motor 11 can be fastened to the roller 10, with the center line of the output shaft coinciding with the center line of the roller 10.

[0045] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a heat pump circulation device may include, for example, an evaporator 21, a condenser 23, and a heat pump 22. The evaporator 21, condenser 23, and heat pump 22 are sequentially connected via pipelines to form a closed loop for refrigerant circulation. It should be noted that a throttling valve 24 is also provided between the evaporator 21 and the condenser 23. During the operation of the heat pump 22 circulation system, the refrigerant is processed by the heat pump 22 into a high-temperature, high-pressure gas. This high-temperature, high-pressure gas then enters the condenser 23 through the pipeline. After being treated by the heat release of the condenser 23, the gas flows out of the condenser 23 and enters the throttling valve 24. In the throttling valve 24, it undergoes further cooling and depressurization. Afterward, it enters the evaporator 21 for heat absorption, becoming a low-temperature, low-pressure gas. Through this reciprocating circulation operation, the condenser 23 continuously releases heat, maintaining a high-temperature state, while the evaporator 21 continuously absorbs heat, maintaining a low-temperature state.

[0046] It is worth noting that the drum 10, evaporator 21, and condenser 23 are sequentially connected by pipes to form a closed drying duct 20, allowing airflow to pass within the drying duct 20. Figure 1 As shown, the air outlet of the drum 10 is connected to the air inlet of the evaporator 21, the air inlet of the drum 10 is connected to the air outlet of the condenser 23, and the air outlet of the evaporator 21 is connected to the air inlet of the condenser 23. When the airflow flows within the drying duct 20, it passes sequentially through the drum 10, the evaporator 21, and the condenser 23. Finally, the gas exiting the condenser 23 re-enters the drum 10, repeating the above flow process. When the airflow passes through the condenser 23, it is heated by the high temperature of the condenser 23. The high-temperature gas then exits the condenser 23 and enters the drum 10 to dry the clothes inside. Because the clothes contain liquid, the gas becomes hot and humid after exiting the drum 10. After being heated by the evaporator 21, the moisture in the gas condenses on the evaporator 21, thus drying the gas and facilitating subsequent drying of the clothes.

[0047] First refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the clothes drying device provided in the embodiment of the present invention. Figure 1 .like Figure 1As shown, the clothes drying device of the present invention may further include a fan 31, a medicine storage device 41, and a spray device.

[0048] The fan 31 is located inside the drying duct 20. The operation of the fan 31 drives the airflow to circulate within the drying duct 20. As shown in the figure, the fan 31 is located in the drying duct 20 between the air outlet of the drum 10 and the air inlet of the evaporator 21. Of course, the fan 31 can also be located in other pipes of the drying duct 20.

[0049] The drug storage device 41 is used to store the drug. The spray device is positioned opposite the heat pump circulation device and is connected to the drug storage device 41 so that the drug can be sprayed onto the condenser 23. The drug storage device 41 may include, for example, a storage tank and a storage box. The spray device may include, for example, a spray nozzle and an atomizing nozzle. The spray device may be located above the condenser 23 in the illustrated position so that liquid is sprayed onto the condenser 23 through the spray device.

[0050] In an optimized embodiment, the agent may include a disinfectant and an aromatherapy agent. When a disinfectant is placed in the storage device 41, it is evaporated into water vapor by the condenser 23 and flows throughout the drying duct 20 under the drive of the fan 31, disinfecting the entire drying duct 20. When an aromatherapy agent is also placed in the storage device 41, the clothes to be treated are placed in the drum 10. The aromatherapy agent can be sprayed onto the condenser 23 through a spray device. Because the condenser 23 is at a high temperature, the aromatherapy agent is evaporated into water vapor and flows through the drying duct 20 under the drive of the fan 31. At this time, because the drum 10 rotates the clothes, it is beneficial for the aromatherapy agent to adhere evenly to the clothes, thereby giving the clothes an aromatherapy treatment.

[0051] In the clothes drying device provided in this embodiment of the invention, the roller 10 and part of the heat pump circulation device are connected by pipelines to form a closed drying duct 20. The fan 31 is located inside the drying duct 20, the medicine storage device 41 is used to store medicine, and the spray device is directly opposite the condenser 23 and is connected to the medicine storage device 41. With the above arrangement, the medicine can be sprayed onto the condenser 23 by the spray device and evaporated into water vapor by the high temperature of the condenser 23. Driven by the fan 31, the medicine circulates in the drying duct 20, thereby disinfecting or fumigateing the entire drying duct 20.

[0052] Continue to refer to Figure 1The spraying device may include a drug delivery device and a first nozzle 61 positioned opposite the condenser 23. In an optimized embodiment, the drug delivery device is connected to a first valve 51 and a drug storage device 41. The drug delivery device is used to deliver the drug from the drug storage device 41 to the first nozzle 61. The drug delivery device may include, for example, a metering pump or a diaphragm pump, to further control the flow rate of the drug. The first nozzle 61 is connected to the first valve 51. When the first valve 51 is in a first state, the first valve 51 connects the drug delivery device to the first nozzle 61 so that the drug from the drug storage device 41 is sprayed onto the condenser 23 through the first nozzle 61.

[0053] In an optimized embodiment, the clothes drying device further includes a control device (not shown in the figure), which is electrically connected to the heat pump circulation device, fan 31, first valve 51, and drive motor 11 to control their start and stop. The control device may be, for example, a microcontroller or a programmable logic controller (PLC) or other device capable of performing control functions.

[0054] In one possible implementation, the drying device further includes a heating device 32 located within a drying duct 20 between the air outlet of the heat pump circulation device and the air inlet of the drum 10. A fan 31 is also located within the drying duct 20 between the air inlet of the heat pump circulation device and the air outlet of the drum 10. A control device is electrically connected to the heating device 32 to control its start and stop. Figure 1 As shown, specifically, the heating device 32 is located within the drying duct 20 between the air outlet of the condenser 23 and the air inlet of the drum 10, and the fan 31 is located within the drying duct 20 between the air inlet of the evaporator 21 and the air outlet of the drum 10. The heating device 32 may include a heating resistance wire, an electric heating rod, and other devices that use electric current for heating. When the drying device is in the sterilization / fragrance mode, the control device can control the operation of the heating device 32, thereby further heating the water vapor flowing out of the condenser 23 to form high-temperature water vapor, thus further improving the sterilization or fragrance effect on the clothes. It is worth noting that the control device can adjust the power of the heating device 32 to control its temperature, thereby regulating the temperature of the water vapor.

[0055] When the drying device is in disinfection / aromatherapy mode, the control device controls the operation of the heat pump circulation device, fan 31, heating device 32, and drive motor 11. The control device also controls the first valve 51 to be in a first state. Since the first valve 51 connects the first nozzle 61 to the drug delivery device, the drug in the storage device 41 can be sprayed onto the condenser 23 through the first nozzle 61. At this time, the heat pump circulation device, fan 31, and drive motor 11 are all operating, and the condenser 23 is at a high temperature, allowing the drug sprayed onto the condenser 23 to evaporate into water vapor. This vapor is then further heated by the heating device 32 to become a high-temperature drug, which circulates within the drying duct 20 under the drive of the fan 31. It should be noted that at this time, the drive motor 11 drives the drum 10 to rotate, which facilitates even contact between the drug and the clothes inside the drum 10.

[0056] Furthermore, the control device can further control the wind speed of fan 31 by adjusting the power of fan 31. For example, when the control device controls fan 31 to operate at its rated power, the wind speed of fan 31 is at its maximum, which helps to increase the flow rate of the agent in the drying duct 20 and further shorten the working time.

[0057] Please refer to the following text. Figure 2 , Figure 2 This is a schematic diagram of the structure of the clothes drying device provided in the embodiment of the present invention. Figure 2 It should be noted that, Figure 2 The drive motor is not shown in the diagram. The drive motor 11 is used to drive the roller 10 to rotate. The connection method between the drive motor and the roller is not described in detail. Figure 2 As shown, the clothes drying device of the present invention may further include a fan 31, a water storage device 42, and a spray device.

[0058] The fan 31 is located inside the drying duct 20. The operation of the fan 31 drives the airflow to circulate within the drying duct 20. As shown in the figure, the fan 31 is located in the drying duct 20 between the air outlet of the drum 10 and the air inlet of the evaporator 21. Of course, the fan 31 can also be located in other pipes of the drying duct 20.

[0059] Continue to refer to Figure 2 The water storage device 42 is used to store water. The spray device is positioned opposite the heat pump circulation device and is connected to the water storage device 42 so that water can be sprayed onto the condenser 23. The water storage device 42 may include, for example, a storage tank and a storage box, and the spray device may include, for example, spray nozzles and atomizing nozzles. (See reference...) Figure 1 The water storage device 42 can be installed on top of the roller 10 in the position shown in the figure so as to spray liquid onto the condenser 23 through the spray device.

[0060] In the clothes drying device provided in this embodiment of the invention, the drum 10 and part of the heat pump circulation device are connected by pipelines to form a closed drying duct 20. The fan 31 is located inside the drying duct 20, and the spray device is directly opposite the condenser 23. The spray device is connected to the water storage device 42. With the above arrangement, water can be sprayed from the spray device onto the condenser 23 and evaporated into water vapor by the high temperature of the condenser 23. Driven by the fan 31, the water circulates in the drying duct 20, thereby performing an air wash treatment on the clothes.

[0061] It is worth noting that "air washing" here means a method of restoring the elasticity of fibers by allowing them to fully stretch under the action of gas at a certain temperature, humidity, and pressure, and with a certain mechanical force.

[0062] Continue to refer to Figure 1 The spraying device may include a water supply device and a first nozzle 61 positioned opposite the condenser 23. In an optimized embodiment, the water supply device is connected to a first valve 51 and a water storage device 42. The water supply device is used to deliver water from the water storage device 42 to the first nozzle 61. The water supply device may include, for example, a metering pump or a diaphragm pump, to further control the water flow rate. The first nozzle 61 is connected to the first valve 51. When the first valve 51 is in a second state, the first valve 51 connects the water supply device to the first nozzle 61 so that water from the water storage device 42 is sprayed onto the condenser 23 through the first nozzle 61.

[0063] In an optimized embodiment, the clothes drying device further includes a control device (not shown in the figure), which is electrically connected to the heat pump circulation device, fan 31, first valve 51, and drive motor 11 to control their start and stop. The control device may be, for example, a microcontroller or a programmable logic controller (PLC) or other device capable of performing control functions.

[0064] In one possible implementation, the drying device further includes a heating device 32 located within a drying duct 20 between the air outlet of the heat pump circulation device and the air inlet of the drum 10. A fan 31 is also located within the drying duct 20 between the air inlet of the heat pump circulation device and the air outlet of the drum 10. A control device is electrically connected to the heating device 32 to control its start and stop. Figure 1As shown, specifically, the heating device 32 is located within the drying duct 20 between the air outlet of the condenser 23 and the air inlet of the drum 10, and the fan 31 is located within the drying duct 20 between the air inlet of the evaporator 21 and the air outlet of the drum 10. The heating device 32 may include a heating resistance wire, an electric heating rod, and other devices that use electric current for heating. When the dryer is in air wash mode, the control device can control the operation of the heating device 32, thereby further heating the water vapor flowing out of the condenser 23 to form high-temperature water vapor, further improving the treatment effect on the clothes. It is worth noting that the control device can adjust the power of the heating device 32 to control its temperature, thereby regulating the temperature of the water vapor.

[0065] When the dryer is in air wash mode, the control device controls the operation of the heat pump circulation device, heating device 32, fan 31, and drive motor 11. The control device also controls the first valve 51 to be in its second state. Since the first valve 51 connects the spray device and the water storage device 42, water in the water storage device 42 can be sprayed onto the condenser 23 through the spray device. At this time, the heat pump circulation device, fan 31, and drive motor 11 are all operating, and the condenser 23 is at a high temperature. This allows the water sprayed onto the condenser 23 to evaporate into water vapor. Driven by the fan 31, this vapor circulates within the drying duct 20 and is heated by the heating device 32 to form high-temperature water vapor. The drive motor 11 then rotates the drum 10, facilitating full contact between the high-temperature water vapor and the clothes, thus removing wrinkles. Furthermore, the high-temperature water vapor also helps remove odors and bacteria from the clothes, further improving their cleanliness.

[0066] Furthermore, the control device can further control the wind speed of fan 31 by adjusting the power of fan 31. For example, when the control device controls fan 31 to operate at rated power, the wind speed of fan 31 is at its maximum, which helps to increase the flow rate of water in the drying duct 20 and further shorten the working time.

[0067] Please refer to the following text. Figure 3 , Figure 3 This is a schematic diagram of the structure of the clothes drying device provided in the embodiment of the present invention. Figure 3 It should be noted that, Figure 3 The drive motor is not shown in the diagram. The drive motor 11 is used to drive the roller 10 to rotate. The connection method between the drive motor and the roller is not described in detail. Figure 3 As shown, the clothes drying device of the present invention may further include a water storage device 42 and a spray device.

[0068] Reference Figure 3The water storage device 42 is used to store water. The spray device is connected to the water storage device 42, as shown in the figure. The spray device can be directed towards the heat pump circulation device, or it can be directed towards other components that are prone to ignition. The water storage device 42 may include, for example, a storage tank and a storage box, and the spray device may include, for example, spray nozzles and atomizing nozzles. (See reference...) Figure 1 The water storage device 42 can be installed on top of the roller 10 in the position shown in the figure so as to spray liquid onto the condenser 23 through the spray device.

[0069] In the clothes drying device provided in this embodiment of the invention, the roller 10 and part of the heat pump circulation device are connected by pipelines to form a closed drying duct 20. The water storage device 42 is used to store water, and the spray device is directly opposite the heat pump circulation device and is connected to the water storage device 42. With the above arrangement, in the event of a fire in the heat pump circulation device, water can be sprayed onto the heat pump circulation device by the spray device, thereby extinguishing the fire in the clothes drying device and ensuring the safe use of the clothes drying device.

[0070] Continue to refer to Figure 1 The spraying device may include a water supply device and a first nozzle 61 positioned opposite the condenser 23. In an optimized embodiment, the water supply device is connected to a first valve 51 and a water storage device 42. The water supply device is used to deliver water from the water storage device 42 to the first nozzle 61. The water supply device may include, for example, a metering pump or a diaphragm pump, to further control the water flow rate. The first nozzle 61 is connected to the first valve 51. When the first valve 51 is in a second state, the first valve 51 connects the water supply device to the first nozzle 61 so that water from the water storage device 42 is sprayed onto the condenser 23 through the first nozzle 61.

[0071] In an optimized embodiment, the clothes drying device further includes a control device (not shown in the figure), which is electrically connected to the heat pump circulation device, fan 31, first valve 51, and drive motor 11 to control their start and stop. The control device may be, for example, a microcontroller or a programmable logic controller (PLC) or other device capable of performing control functions.

[0072] In one possible implementation, a water receiving tray 43 and a return water pump are also included. The water receiving tray 43 faces the condenser 23 and evaporator 21 and is located on the side of the condenser 23 and evaporator 21 away from the spray device. The water receiving tray 43 is connected to the water storage device 42 via the return water pump. The control device is electrically connected to the return water pump so that the control device can control the start and stop of the return water pump. (Refer to...) Figure 3The drip tray 43 can be located below the evaporator 21 and condenser 23 as shown in the figure, so that the liquid sprayed by the spray device can drip into the drip tray 43 and be collected by the drip tray 43. Furthermore, during the drying process of clothes in the drying device, the condensate on the evaporator 21 can also drip into the drip tray 43. A return water pump can be installed in the drip tray 43 so that the liquid in the drip tray 43 can be transported to the water storage device 42 by the return water pump.

[0073] When the clothes dryer is in fire extinguishing mode, the control device controls the return water pump to transport the liquid in the water tray 43 to the water storage device 42. The control device also controls the heat pump circulation device, heating device 32, fan 31, and drive motor 11 to stop working. Furthermore, the control device controls the first valve 51 to be in a second operating state, so that water is sprayed onto the evaporator 21 and condenser 23. At this time, the water in the water storage device 42 is sprayed onto the condenser 23 and evaporator 21 through the spray device. Simultaneously, because the control device controls the return water pump to operate, the water recovered in the water tray 43 is transported to the water storage device 42, thereby achieving water recycling.

[0074] Furthermore, the drying device may also include a temperature sensor, which is installed inside the heat pump circulation unit. The control device is electrically connected to the water level sensor 421, and the control device is used to control the drying device to enter the fire extinguishing mode based on the electrical signal from the water level sensor 421. It is worth noting that the temperature sensor is used to detect the temperature inside the heat pump circulation unit. When the heat pump circulation unit catches fire, the temperature detected by the temperature sensor reaches the preset temperature, and the first valve 51 enters the second working state, that is, the drying device enters the fire extinguishing mode so that water can be sprayed onto the evaporator 21 and the condenser 23.

[0075] Alternatively, the dryer may also include a current sensor, which is installed in the circuit of the heat pump cycle device. By detecting abnormal current values, it can determine whether a fire has occurred. When the current sensor detects an abnormal current, the first valve 51 is in a second operating state, that is, the dryer is in fire extinguishing mode, so that water can be sprayed onto the evaporator 21 and the condenser 23.

[0076] Furthermore, the aforementioned drying device also includes a filter device 422, which is disposed within the water storage device 42. Since the water recovered from the drip tray 43 may contain dust and lint washed down from the heat pump cycle, the water from the drip tray 43 may be contaminated with dust and lint after being transported to the water storage device 42 by the return water pump. To prevent further accumulation of dust and lint, a filter device 422 is installed within the water storage device 42. This prevents dust and lint from being sprayed onto the evaporator 21 and condenser 23 again, thus ensuring the performance of the condenser 23 and evaporator 21 and preventing the drying effect from being affected by dust accumulation on the condenser 23 and evaporator 21. In one specific implementation, the filter device 422 may include, for example, a filter screen and an activated carbon filter element.

[0077] Continue to refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a clothes drying device including the structure of the above embodiments provided in the embodiments of the present invention.

[0078] In one specific implementation, the outlets of both the drug delivery device and the water delivery device are connected to the first valve 51. When the first valve 51 is in the first state, only the drug delivery device is connected to the first nozzle, and the agent in the drug storage device 41 can be sprayed onto the condenser 23 through the first nozzle 61; when the first valve 51 is in the second state, only the water delivery device is connected to the first nozzle, and the agent in the water storage device 42 can be sprayed onto the condenser 23 through the first nozzle 61.

[0079] In a preferred implementation, the first valve 51 includes a solenoid valve. Solenoid valves offer advantages such as good sealing performance, simple control, and low cost, which helps reduce the production cost of the drying device. Alternatively, the first valve 51 may also include other three-way valves capable of controlling valve precision, such as a butterfly valve. The control device can further control the flow rate of liquid passing through the first valve 51 by controlling the valve opening.

[0080] In one possible implementation, the spraying device may further include a first nozzle 61 and a second nozzle 62, with the first nozzle 61 facing the condenser 23 and the second nozzle 62 facing the evaporator, and the first nozzle 61 and the second nozzle 62 connected by a second valve 52. As shown in the figure, the first nozzle 61 may be located above the condenser 23 in the illustrated position, so as to spray liquid onto the condenser 23 through the first nozzle 61. The second nozzle 62 may be located above the evaporator 21 in the illustrated position, so as to spray liquid onto the evaporator 21 through the second nozzle 62. When the first valve 51 is in the first state, it connects only the drug delivery device to the second valve 52, and the second valve 52 connects only the first valve 51 to the first nozzle 61, so that the medicine in the drug storage device 41 can be sprayed onto the condenser 23 through the first nozzle 61; when the first valve 51 is in the second state, it connects only the water delivery device to the second valve 52, and the second valve 52 connects only the first valve 51 to the first nozzle 61 and the second nozzle 62, so that the medicine in the water storage device 42 can be sprayed onto the condenser 23 through the first nozzle 61, and can also be sprayed onto the evaporator 21 through the second nozzle 62.

[0081] In a preferred implementation, the second valve 52 includes a solenoid valve, which has advantages such as good sealing performance, simple control, and low cost, thus helping to reduce the production cost of the drying device. Alternatively, the second valve 52 may also include other three-way valves that can control valve precision, such as a butterfly valve. The control device can further control the flow rate of liquid flowing through the second valve 52 by controlling the valve opening.

[0082] When the dryer is in cleaning mode, the control device stops the heat pump circulation device, heating device 32, fan 31, and drive motor 11. The control device also controls the first valve 51 and the second valve 52 to be in their second state. It is worth noting that the dryer performs a cleaning operation in cleaning mode. At this time, water in the water storage device 42 is sprayed onto the condenser 23 and evaporator 21 through the first nozzle 61 and the second nozzle 62, respectively, to remove lint and dust from the condenser 23 and evaporator 21, thus ensuring the performance of the condenser 23 and evaporator 21 and preventing dust accumulation on the condenser 23 and evaporator 21 from affecting the drying effect.

[0083] In one possible implementation, a preset time can be set in the control device based on usage experience. After each preset time, the control device will control the drying device to enter the cleaning mode, thereby ensuring the performance of the condenser 23 and the evaporator 21 and avoiding the drying effect being affected by dust accumulation in the condenser 23 and the evaporator 21.

[0084] Preferably, the above-mentioned drying device further includes a water level sensor 421, which is disposed inside the water storage device 42. The control device is electrically connected to the water level sensor 421. When the water level sensor 421 detects that the liquid in the water storage device 42 has reached a preset water level, the first valve 51 and the second valve 52 are in a second state. That is, the control device is used to control the drying device to be in cleaning mode according to the electrical signal of the water level sensor 421. It is worth noting that the water level sensor 421 can be used to detect the volume of water in the water storage device 42. When the water storage device 42 stores a certain volume of water, the water level sensor 421 can transmit an electrical signal to the control device, causing the first valve 51 and the second valve 52 to be in the second state, that is, the drying device is in cleaning mode, thereby performing cleaning operations, while also preventing excessive water from overflowing from the water storage device 42.

[0085] In addition, in some other possible implementations, the water level sensor 421 can also monitor whether the water in the water storage device 42 is insufficient. When the water level sensor 421 detects that the water in the water storage device 42 is at a low water level, the control device can control the return water pump to deliver water to the water receiving pan 43.

[0086] Alternatively, a load-bearing sensor may also be included. The load-bearing sensor is located at the bottom of the water storage device 42. When the water in the water storage device 42 reaches a preset weight, the load-bearing sensor is used to transmit an electrical signal to the control device, thereby causing the first valve 51 and the second valve 52 to be in a second state, that is, the clothes dryer is in the cleaning mode.

[0087] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
