Description

Technical Field

[0001] This application relates to the field of clothes dryer technology, and specifically to a clothes dryer. Background Technology

[0002] A clothes dryer is a household appliance that uses heating wires or a heat pump system to instantly evaporate and dry the moisture in washed clothes. As living standards improve, consumers' demands for clothing care are becoming increasingly sophisticated, with the need for drying intimate items such as shoes and socks becoming more prominent in addition to regular clothing.

[0003] Currently, while placing shoes and socks directly inside the drum can achieve drying, the shoes and socks are easily damaged by the drum wall, leading to user dissatisfaction. Therefore, when drying shoes and socks in a dryer, a drying rack is usually added inside the drum. The shoes and socks are hung or laid flat on the drying rack to prevent them from colliding with the drum wall.

[0004] However, due to the large space inside the drum, the hot air is dispersed and difficult to concentrate on the inside of the shoes and socks, resulting in low drying efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems and other issues.

[0006] Another objective of this invention is to provide a dryer that effectively improves the efficiency of drying shoes and socks.

[0007] The purpose of this invention is not limited to the purposes mentioned above, and those skilled in the art will clearly understand other purposes not mentioned from the following description.

[0008] In some embodiments of this application, a clothes dryer is provided, the clothes dryer comprising:

[0009] Box;

[0010] A roller is disposed inside the box, and a clothes drying chamber is formed inside the roller;

[0011] An air duct is provided in the space between the outside of the roller and the housing, and air flows sequentially through the bottom air duct, the first rear air duct and the front air duct to form a first air circuit;

[0012] A fan is used to drive air to circulate within the air duct;

[0013] A heat pump system, including a condenser, an evaporator, and a compressor, forms a refrigerant circuit for heating the air in the duct.

[0014] A shoe and sock drying chamber is located in the top air duct. The air inlet of the shoe and sock drying chamber is connected to the second rear air duct, and the air outlet of the shoe and sock drying chamber is connected to the front air duct. The cross-sectional dimension of the shoe and sock drying chamber in the height direction is smaller than the cross-sectional dimension of the roller. Air flows through the bottom air duct, the second rear air duct, the top air duct and the front air duct in sequence to form a second air circuit.

[0015] A door is provided at the opening of the shoe and sock drying chamber for closing or opening the shoe and sock drying chamber;

[0016] A first valve is located at the connection between the first rear air duct and the second rear air duct, and the first valve is used to switch the airflow path.

[0017] and a control unit, wherein the control unit is configured to:

[0018] In response to a clothes drying signal, the fan and the compressor are started, and the first valve is controlled to be in a first working state, so that air is circulated through the first air circuit to dry the clothes in the drum;

[0019] In response to the shoe and sock drying signal, the fan and the compressor are started, and the first valve is controlled to be in the second working state, so that air is circulated through the second air circuit to dry the shoes and socks in the shoe and sock drying chamber.

[0020] The above technical solution has the following advantages or beneficial effects: the air duct is set in the space between the outside of the drum and the box, and the air flows through the bottom air duct, the first rear air duct and the front air duct in sequence to form a first air circuit; a shoe and sock drying chamber is set in the dryer, the shoe and sock drying chamber is located in the top air duct, the air inlet of the shoe and sock drying chamber is connected to the second rear air duct, and the air outlet of the shoe and sock drying chamber is connected to the front air duct, and the air flows through the bottom air duct, the second rear air duct, the top air duct and the front air duct in sequence to form a second air circuit; a first valve is also provided at the connection between the first rear air duct and the second rear air duct, and the first valve can be used to switch the airflow path. In response to a shoe and sock drying signal, the fan and compressor are activated, and the first valve is controlled to enter the second operating state, allowing air to circulate through the second air circuit to dry the shoes and socks in the drying chamber. Because the cross-sectional dimension of the air flowing into the shoe and sock drying chamber in the vertical direction is smaller than that flowing into the drum, the air velocity flowing into the shoe and sock drying chamber is higher, resulting in a higher gas velocity flowing over the surface of the shoes and socks. The space of the shoe and sock drying chamber is also smaller than that inside the drum, resulting in a higher gas temperature inside the shoe and sock drying chamber, and consequently, a higher gas temperature flowing over the surface of the shoes and socks. By increasing the gas velocity and temperature over the surface of the shoes and socks, the drying efficiency of the shoes and socks is significantly improved.

[0021] In addition, in response to the clothes drying signal, the fan and compressor are started, and the first valve is controlled to be in the first working state, so that air is circulated through the first air circuit to dry the clothes in the drum. Thus, in this embodiment, clothes are placed in the drum and shoes and socks are placed in the shoe and sock drying chamber. By controlling the working state of the first valve, the dryer can realize the shoe and sock drying function and the clothes drying function respectively.

[0022] In some embodiments of this application, a clothes dryer is provided, wherein the first valve is a regulating valve; the control unit is further configured to,

[0023] In response to the mixed drying signal, the fan and the compressor are started, and the first valve is controlled to be in the third working state, so that the bottom air duct is connected to the first rear air duct and the second rear air duct respectively, so as to dry the clothes and the shoes and socks simultaneously.

[0024] The above technical solution has the following advantages or beneficial effects: the first valve is a regulating valve, which can regulate the opening of air flowing from the bottom air duct into the first rear air duct, and regulate the opening of air flowing from the bottom air duct into the second rear air duct; in response to the mixed drying signal, the fan and compressor are started, and the first valve is controlled to be in the third working state, so that the bottom air duct can be connected to the first rear air duct and the second rear air duct respectively, so as to dry clothes and shoes and socks simultaneously, thereby realizing the function of simultaneous drying of clothes and shoes and socks.

When in response to the clothes drying signal, the fan and compressor are started, the first valve is controlled to be in the first working state, and the second valve is closed to close the channel between the top air duct and the front air duct. This can prevent the heat of the air in the drum from entering the shoe and sock drying chamber, thereby effectively ensuring the drying efficiency of the clothes.

[0028] In some embodiments of this application, a clothes dryer is provided, the clothes dryer further comprising:

[0036] The above technical solution has the following advantages or beneficial effects: A humidity sensor is installed at the air outlet of the shoe and sock drying chamber. The humidity sensor can monitor the air outlet humidity of the shoe and sock drying chamber in real time. When the air outlet humidity of the shoe and sock drying chamber is detected to be below the preset humidity limit, it indicates that the shoes and socks are dried. Then, the heat pump system is controlled to be turned off, thereby accurately controlling the drying to stop and preventing the shoes and socks from being over-dried or under-dried.

[0037] In some embodiments of this application, a clothes dryer is provided, wherein the first valve is a regulating valve; the air outlet of the shoe and sock drying chamber is further provided with a temperature sensor, the temperature sensor being used to monitor the air outlet temperature of the shoe and sock drying chamber in real time; the control unit is further configured to,

By connecting the bottom air duct with the first rear air duct and the second rear air duct respectively, the hot air in the shoe and sock drying chamber can be better dissipated into the drum, thereby improving the cooling speed of the shoes and socks.

[0041] In addition, when the air outlet temperature of the shoe and sock drying chamber drops below the preset temperature limit, indicating that the shoes and socks are already cooled, the dryer is controlled to stop running, thus accurately controlling the cooling process and preventing energy waste.

[0042] In some embodiments of this application, a clothes dryer is provided, wherein the shoe and sock drying chamber is provided with a plurality of breathable partitions, the breathable partitions being used to separate and place the shoes and socks.

[0062] A clothes dryer is a household appliance that uses heating wires or a heat pump system to instantly evaporate and dry the moisture in washed clothes. As living standards improve, consumers' demands for clothing care are becoming increasingly sophisticated, with the need for drying intimate items such as shoes and socks becoming more prominent in addition to regular clothing.

[0063] Currently, while placing shoes and socks directly inside the drum can achieve drying, the shoes and socks are easily damaged by the drum wall, leading to user dissatisfaction. Therefore, when drying shoes and socks in a dryer, a drying rack is usually added inside the drum. The shoes and socks are hung or laid flat on the drying rack to prevent them from colliding with the drum wall.

[0064] However, due to the large space inside the drum, the hot air is dispersed and difficult to concentrate on the inside of the shoes and socks, resulting in low drying efficiency.

[0065] To solve the above-mentioned technical problems, this application proposes a clothes dryer.

[0066] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a clothes dryer provided in an exemplary embodiment of this application.

[0067] like Figure 1 As shown, the dryer provided in this embodiment of the invention may include a housing 1. The housing 1 may be constructed as the outer shell of the dryer. The housing 1 typically has a hollow cuboid structure. It should be noted that in other embodiments, the external shape of the housing 1 can be designed as needed, and is not limited here.

[0076] In some embodiments of this application, the control panel may be equipped with a display screen. The display screen may show the current operating status of the dryer. The current operating status of the dryer may be preheating, drying, or cooling.

[0077] In some embodiments of this application, if the dryer malfunctions or encounters an abnormality, the display screen can show corresponding error codes or prompts to help the user quickly locate the problem.

[0078] In some embodiments of this application, the control panel may be equipped with a start switch to start a corresponding program. The control panel may also be equipped with a pause switch to pause the current operation. Finally, the control panel may be equipped with a cancel switch to cancel the current operation.

[0079] In some embodiments of this application, the dryer may include a rear drum seal. The rear drum seal is located at the rear end of the drum 13, connecting the drum 13 and the rear end cover or related fixing parts. The rear drum seal can be used to ensure the airtightness of this area. The rear drum seal can prevent cold air from entering from the rear end of the drum 13, thereby maintaining the temperature of the hot air inside the drum 4 and improving the heat exchange efficiency between the hot air and the clothes.

[0080] In some embodiments of this application, the dryer may include a front drum seal. The front drum seal is located at the front end of the drum 13, connecting the drum 13 and the front cover or related fixing part. The front drum seal can be used to ensure the airtightness of this area. The front drum seal can prevent heat leakage, thereby improving the heat exchange efficiency between hot air and clothing.

[0081] In some embodiments of this application, the rear seal of the cylinder can be a door seal ring. The front seal of the cylinder can be a door seal ring. The door seal ring can be an annular structure. The door seal ring can be made of an elastic sealing material.

[0082] In some embodiments of this application, the dryer may include a drum air inlet 2. The drum air inlet 2 is located at the rear end of the drum 13, and the drum air inlet 2 can introduce high-temperature air into the interior of the drum 13 to provide the necessary heat for drying clothes.

[0083] In some embodiments of this application, the dryer may include a drum air outlet 14. The drum air outlet 14 is disposed at the front end of the drum 13, and the drum air outlet 14 can discharge the moisture and heat generated during the drying process from the inside of the drum 13 to maintain air circulation and drying efficiency inside the drum 13.

[0084] In some embodiments of this application, the dryer may include a drum assembly. The drum assembly may be disposed inside the housing 1. The drum assembly may extend along the front-rear direction of the housing 1. A clothes drying chamber may be formed inside the drum assembly. A drum opening may be formed on the front end face of the drum assembly. The drum opening communicates with the interior of the clothes drying chamber. The drum opening is directly opposite the clothes inlet and the door 15 of the housing 1. After the door 15 is opened, clothes can be sequentially placed into the clothes drying chamber inside the drum assembly through the clothes inlet on the front side of the housing 1 and the drum opening at the front end of the drum assembly for drying, cooling, and other operations. When the housing 1 is closed, the housing 1 can simultaneously close the clothes inlet and the drying chamber.

[0085] In some embodiments of this application, the cylinder assembly may include an outer cylinder. The outer cylinder may be disposed inside the housing 1. The outer cylinder may be configured to house a heat pump system. The heat pump system may include a compressor 17, an evaporator 18, a condenser 19, etc.

[0086] In some embodiments of this application, the outer cylinder may be made of plastic and can be injection molded. Injection molding can reduce costs. The outer cylinder may also be made of metal.

[0087] In some embodiments of this application, the drum assembly may include a drum 13. The drum 13 may be disposed inside the outer drum. A clothes drying chamber may be formed inside the drum 13. The clothes drying chamber inside the drum 13 may be used to hold clothes to be dried.

[0088] In some embodiments of this application, the roller 13 can be rotatably disposed inside the outer cylinder. When the roller 13 rotates relative to the outer cylinder, the roller 13 can drive the clothes to rotate relative to the outer cylinder, thereby realizing the drying function of the clothes in the drying chamber of the roller 13 and improving the uniformity of drying.

[0089] In some embodiments of this application, the outer cylinder and the roller 13 may also be arranged coaxially inside and outside. The front end of the outer cylinder and the front end of the roller 13 may have openings arranged opposite to each other. The front end opening of the outer cylinder and the front end opening of the roller 13 may be combined to form the cylinder opening of the cylinder assembly.

[0090] In some embodiments of this application, the dryer may include a rotation system. The rotation system may include a belt 3. The transmission system may include a motor 7. The motor 7 may have a motor shaft, through which power of the motor 7 can be transmitted.

[0091] The belt 3 can be connected to the drum 13 and the motor shaft respectively, so that the belt 3 can be driven by the motor 7 to rotate, thereby causing the drum 13 to rotate, so that the clothes can tumble up and down in the drum 13 and speed up the drying speed of the clothes.

[0092] In some embodiments of this application, the belt 3 may be connected to the rear end of the roller 13. A corresponding transmission mechanism connected to the belt 3 is provided on the rear end of the roller 13.

[0093] In some embodiments of this application, the motor 7 can adjust the rotational speed of the roller 13 via a control circuit. The motor 7 can also adjust the rotation angle of the roller 13 via a control circuit. Furthermore, the motor 7 can adjust the rotation direction of the roller 13 via a control circuit. Finally, the motor 7 can adjust the rotation time of the roller 13 via a control circuit.

[0094] The motor 7 adjusts the operating state of the drum 13 via a control circuit, adapting to different drying programs and user needs. For example, for thick clothing, the motor 7 can be controlled to use a lower speed to prevent excessive wear and tear. For thin clothing, the motor 7 can be controlled to use a higher speed to increase the drying rate. To prevent clothing from clumping and affecting the drying effect, the rotation direction of the drum 13 can also be changed by the motor 7 to ensure more even drying of the clothing.

[0095] In some embodiments of this application, the dryer may include a fan 8. The fan 8 may consist of a motor 7 and an impeller. The impeller may be disposed in a rear air duct. The fan 8 can drive air to circulate within the air duct, thereby accelerating the drying speed of clothes and socks.

[0096] In some other embodiments, the fan 8 may also be located at other locations in the air duct.

[0097] After the drying program stops, the impeller can be rotated via motor 8 to allow cold air to flow into drum 13, accelerating the cooling of the clothes. It should be noted that the cooling duration can be adjusted according to actual conditions to ensure the clothes are at a suitable temperature when removed.

[0098] In some embodiments of this application, the dryer may include a heat pump system. The heat pump system may include a compressor 17. The heat pump system may include an evaporator 18. The heat pump system may include a condenser 19. In some embodiments of this application, the condenser 19, evaporator 18, and compressor 17 may form a refrigerant circuit for heating air in the duct. The refrigerant may be a refrigerant.

[0099] In some embodiments of this application, the evaporator 18 and the condenser 19 may be sequentially arranged within the air duct along the airflow direction. The evaporator 18 and the condenser 19 may be sequentially arranged within the bottom air duct 9 along the airflow direction. The compressor 17 may be located outside the air duct. The compressor 17 may be located on the top surface of the bottom air duct 9.

[0100] Both evaporator 18 and condenser 19 are types of heat exchangers. When the dryer is working, the evaporator 18 is at a low temperature, while the condenser 19 is at a high temperature.

[0101] In some embodiments of this application, moisture in the clothes inside the drum 13 evaporates into the air at high temperature, forming a high-temperature, high-humidity circulating gas. The circulating gas enters the bottom air duct 9 through the drum outlet 14, and condensation occurs when it passes through the low-temperature evaporator 18, thus carrying away moisture from the air passing through the evaporator 18. The air then flows through the condenser 19, where it is heated and becomes high-temperature dry gas, which then sequentially passes through the first rear air duct 5 and the drum inlet 2 back into the drum 13 to dry the clothes, thus forming a cycle.

[0102] In other embodiments of this application, moisture in the shoes and socks inside the shoe and sock drying chamber 11 evaporates into the air at high temperature, forming a high-temperature, high-humidity circulating gas. The circulating gas enters the bottom air duct 9 through the front air duct 16, and condensation occurs when it passes through the low-temperature surface evaporator 18, thereby carrying away moisture from the air passing through the evaporator 18. The air then flows through the condenser 19, where it is heated and becomes high-temperature dry gas, which then returns to the shoe and sock drying chamber 11 through the second rear air duct 4 to dry the shoes and socks, thus forming a cycle.

[0103] In some embodiments of this application, the dryer may include a drain hole 10. The drain hole 10 may be located in the bottom air duct 9. The drain hole 10 may communicate with the bottom water storage tank. During the operation of the dryer, the surface of the evaporator 18 is at a low temperature. When the circulating gas passes through the low-temperature evaporator 18, condensate will be released. The released condensate can flow from the drain hole 10 to the bottom water storage tank.

[0104] In some embodiments of this application, the dryer may include an air duct. The air duct may be a closed ventilation pipe. The air duct may be located in the space between the outside of the drum 13 and the housing 1.

[0105] The air duct may include a front air duct 16 disposed on the front side of the drum 13. The front air duct 16 may be connected to the drum air outlet 14. The front air duct 16 may be connected to the top air duct through the air outlet of the shoe and sock drying chamber 11. The front air duct 16 may be connected to the bottom air duct 9.

[0106] The air duct may include a bottom air duct 9 disposed in the space between the bottom of the roller 13 and the bottom of the housing 1. The bottom air duct 9 may be connected to the first rear air duct 5. The bottom air duct 9 may be connected to the second rear air duct 4. The bottom air duct 9 may be connected to the front air duct 16.

[0107] The air duct may include a top air duct disposed in the space between the top of the drum 13 and the top of the housing 1. The top air duct can be connected to the second rear air duct 4 through the air inlet of the shoe and sock drying chamber 11. The top air duct can be connected to the front air duct 16 through the air outlet of the shoe and sock drying chamber 11.

[0108] The air duct may include a rear air duct located behind the drum 13. The rear air duct may include a first rear air duct 5. The first rear air duct 5 may be connected to the bottom air duct 9. The first rear air duct 5 may be connected to the drum air inlet 2. The rear air duct may include a second rear air duct 4. The second rear air duct 4 may be connected to the bottom air duct 9. The second rear air duct 4 may be connected to the shoe and sock drying chamber 11.

[0109] Referring to the circulating gas flow direction in the attached diagram, air can sequentially pass through the bottom air duct 9, the first rear air duct 5, and the front air duct 16 to form a first air circuit. Air can also sequentially pass through the bottom air duct 9, the second rear air duct 4, the top air duct, and the front air duct 16 to form a second air circuit.

[0110] In some embodiments of this application, the dryer may include a first deflector. The first deflector may be disposed at the connection between the first rear air duct 5 and the drum 13. The first deflector can be used to guide air into the drum 13.

[0111] Therefore, by guiding air into the drum through the first guide plate, the air can flow better over the surface of the clothes, thereby improving the drying efficiency of the clothes.

[0112] In some other embodiments of this application, the dryer may include a second deflector. The second deflector may be disposed between the second rear air duct 4 and the air inlet of the shoe and sock drying chamber 11. The second deflector can be used to guide airflow over the surface of shoes and socks.

[0113] Therefore, the second deflector guides air to flow better over the surface of the shoes and socks, thereby improving the drying efficiency of the shoes and socks.

[0114] In some embodiments of this application, the deflector can be a fixed deflector. The fixed deflector can be arc-shaped or zigzag-shaped and is fixed inside the air duct by welding or bolts. The deflector can also be an adjustable deflector. The adjustable deflector can have a built-in electric or manual rotating shaft, supporting multi-angle adjustment. The adjustment angle can be from 0° to 90°.

[0115] In other embodiments of this application, the deflector may be an arc-shaped deflector. An arc-shaped deflector can guide the airflow in a fan-shaped diffusion pattern. The deflector may also be a porous deflector. A porous deflector has honeycomb or strip-shaped pores on its surface, which can disperse the airflow and increase the contact area.

[0116] In some embodiments of this application, the first guide plate can be an arc-shaped guide plate, which is more suitable for the uniform distribution of hot air in the drum 13. The second guide plate can be a perforated guide plate, which is more suitable for intensive drying of shoes and socks in the shoe and sock drying chamber 11.

[0117] In some embodiments of this application, the dryer may include a shoe and sock drying system. The shoe and sock drying system may include a shoe and sock drying chamber 11. The shoe and sock drying chamber 11 is disposed in a top air duct. The air inlet of the shoe and sock drying chamber 11 may be connected to a second rear air duct 4. The air outlet of the shoe and sock drying chamber 11 may be connected to a front air duct 16.

[0118] In some embodiments of this application, the shoe and sock drying chamber 11 can be used to hold shoes and socks to be dried. Several breathable partitions can be provided inside the shoe and sock drying chamber. The breathable partitions are used to separate the shoes and socks for placement. A single space enclosed by several breathable partitions can be used to hold a single pair of shoes and socks. Separating the shoes and socks by using breathable partitions allows for even drying of the shoes and socks and also facilitates easy access for the user.

[0119] In some embodiments of this application, the shoe and sock drying chamber 11 is made of plastic. Since the insulation effect of plastic is far superior to that of the metal drum 13, the shoe and sock drying chamber 11 radiates heat outward slowly, and the temperature of the circulating gas flowing into the shoe and sock drying chamber 11 will be much higher than the temperature of the circulating gas inside the drum 13.

[0120] In some embodiments of this application, the sidewall of the shoe and sock drying chamber 11 may be embedded with an activated carbon filter. By embedding an activated carbon filter in the sidewall of the shoe and sock drying chamber 11, odors from shoes and socks can be effectively absorbed, preventing cross-contamination of bacteria.

[0121] In some embodiments of this application, the cross-sectional dimension of the shoe and sock drying chamber 11 in the vertical direction can be smaller than the cross-sectional dimension of the drum. The cross-sectional dimension of the shoe and sock drying chamber 11 being smaller than the cross-sectional dimension of the drum in the vertical direction can reach a predetermined size or higher.

[0122] The shoe and sock drying system may include a door 12. The door 12 may be located at the opening of the shoe and sock drying chamber 11. The door 12 can open the shoe and sock drying chamber 11 for taking in and taking out shoes and socks. The door 12 can close the shoe and sock drying chamber 11 to facilitate the shoe and sock drying function.

[0123] The shoe and sock drying system may include a first valve 6. The first valve 6 may be located at the connection between the first rear air duct 5 and the second rear air duct 4. The first valve 6 may be used to switch the airflow path.

[0124] In some embodiments of this application, the first valve 6 can be controlled to be in a first operating state, such that the bottom air duct 9 is connected to the first rear air duct 5, and air circulates through the first air circuit. The first operating state can be a closed state or an open state.

[0125] In other embodiments of this application, the first valve 6 can be controlled to be in a second operating state, such that the bottom air duct 9 is connected to the second rear air duct 4, and air circulates through the second air circuit. The second operating state can be a closed state or an open state.

[0126] In some embodiments of this application, the working states of the first working state and the second working state are reversed.

[0127] In some embodiments of this application, the dryer may further include a second valve. The second valve may be located at the air outlet of the shoe and sock drying chamber 11. The second valve can be used to open the passage between the top air duct and the front air duct. The second valve can also be used to close the passage between the top air duct and the front air duct.

[0128] In some embodiments of this application, the valve may be a regulating valve. The valve may be a throttle valve. This embodiment does not limit the specific type of valve.

[0129] In some embodiments of this application, the dryer may include a humidity monitoring system. The humidity monitoring system may include a humidity sensor. The humidity sensor may be located at the air outlet of the shoe and sock drying chamber 11. The humidity sensor can be used to monitor the humidity of the air outlet of the shoe and sock drying chamber 11 in real time.

[0130] The humidity level of the air outlet of the shoe and sock drying chamber 11 can indirectly reflect the dryness or wetness of the shoes and socks inside. The humidity level of the shoes and socks inside the drying chamber 11 is positively correlated with the humidity level of the air outlet. If the humidity level of the air outlet of the drying chamber 11 is high, the humidity level of the shoes and socks inside the drying chamber 11 will be high. If the humidity level of the air outlet of the drying chamber 11 is low, the humidity level of the shoes and socks inside the drying chamber 11 will be low.

[0131] In some embodiments of this application, the dryer may include a temperature monitoring system. The temperature monitoring system may include a temperature sensor. The temperature sensor may be located at the air outlet of the shoe and sock drying chamber 11. The temperature sensor can be used to monitor the outlet air temperature of the shoe and sock drying chamber 11 in real time.

[0132] The outlet air temperature of the shoe and sock drying chamber 11 can indirectly reflect the temperature of the shoes and socks inside the chamber. The temperature of the shoes and socks inside the chamber is positively correlated with the outlet air temperature. If the outlet air temperature is high, the temperature of the shoes and socks inside the chamber will be high. If the outlet air temperature is low, the temperature of the shoes and socks inside the chamber will be low.

[0133] In some embodiments of this application, the dryer may further include a control unit. The control unit may be electrically connected to the fan, the compressor, and the first valve, respectively.

[0134] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure provided in an exemplary embodiment of this application during the drying of clothes.

[0135] In some embodiments of this application, the control unit may be configured to perform the following step S110:

[0136] S110, in response to the clothes drying signal, starts the fan and compressor, controls the first valve to be in the first working state, so that air circulates through the first air circuit to dry the clothes in the drum.

[0137] In S110, the clothes drying signal indicates that the clothes inside the drum are being dried. The clothes drying signal can be sent via the control panel on the dryer. The clothes drying signal can also be sent via a mobile terminal connected to the dryer. The control unit receives the clothes drying signal and responds promptly.

[0138] In some embodiments of this application, in response to a clothes drying signal, a fan can be activated to operate at a set speed. For example, the set speed may be 800 revolutions per minute.

[0139] In some embodiments of this application, in response to a clothes drying signal, the compressor can be activated to operate according to a set power. The set power can be the product of the rated power and a set percentage. For example, the set power can be 50% of the rated power.

[0140] In some embodiments of this application, in response to a clothes drying signal, the first valve can be controlled to be in an open state, allowing air to circulate through a first air circuit to dry the clothes in the drum. In response to a clothes drying signal, the first valve can be controlled to be in a closed state, allowing air to circulate through the first air circuit to dry the clothes in the drum.

[0141] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure provided in an exemplary embodiment of this application during the drying of shoes and socks.

[0142] In some other embodiments of this application, the control unit may be configured to perform the following step S210:

[0143] S210, in response to the shoe and sock drying signal, starts the fan and compressor, controls the first valve to the second working state, so that air circulates through the second air circuit to dry the shoes and socks in the shoe and sock drying chamber.

[0144] In S210, the shoe and sock drying signal indicates that the shoes and socks in the shoe and sock drying chamber are being dried. The shoe and sock drying signal can be sent via the control panel on the dryer. The shoe and sock drying signal can also be sent via a mobile terminal connected to the dryer. The control unit receives the shoe and sock drying signal and responds promptly.

[0145] In response to the shoe and sock drying signal, the fan and compressor can be started in the same manner as in the above embodiment, and will not be described in detail here.

[0146] In some embodiments of this application, in response to a shoe and sock drying signal, the first valve can be controlled to be in an open state, allowing air to circulate through a second air circuit to dry the shoes and socks in the shoe and sock drying chamber. In response to a shoe and sock drying signal, the first valve can be controlled to be in a closed state, allowing air to circulate through the second air circuit to dry the shoes and socks in the shoe and sock drying chamber.

[0147] In some embodiments of this application, if the first working state is an on state, then the second working state is a off state. If the first working state is a off state, then the second working state is an on state.

[0148] As can be seen from S110 and S210 above, when responding to the shoe and sock drying signal, the fan and compressor are started, and the first valve is controlled to be in the second working state, so that the air circulates through the second air circuit to dry the shoes and socks in the shoe and sock drying chamber. Since the cross-sectional dimension of the air flowing into the shoe and sock drying chamber in the height direction is smaller than the cross-sectional dimension of the air flowing into the drum, the air velocity flowing into the shoe and sock drying chamber will be higher, and thus the gas velocity flowing over the surface of the shoes and socks will be higher. The space of the shoe and sock drying chamber is also smaller than the space inside the drum, so the gas temperature inside the shoe and sock drying chamber is higher, and thus the gas temperature flowing over the surface of the shoes and socks will be higher. By increasing the gas velocity and temperature over the surface of the shoes and socks, the drying efficiency of the shoes and socks is greatly improved.

[0149] In addition, in response to the clothes drying signal, the fan and compressor are started, and the first valve is controlled to be in the first working state, so that air is circulated through the first air circuit to dry the clothes in the drum. Thus, in this embodiment, clothes are placed in the drum and shoes and socks are placed in the shoe and sock drying chamber. By controlling the working state of the first valve, the dryer can realize the shoe and sock drying function and the clothes drying function respectively.

[0150] In some other embodiments of this application, the first valve is a regulating valve. The control unit can be configured to perform the following step S310:

[0151] S310, in response to the mixed drying signal, starts the fan and compressor, controls the first valve to the third working state, so that the bottom air duct is connected to the first rear air duct and the second rear air duct respectively, and simultaneously dries clothes and shoes and socks.

[0152] In S310, the mixed drying signal indicates that clothes in the drum and shoes and socks in the shoe and sock drying chamber are dried simultaneously. The mixed drying signal can be sent via the control panel on the dryer. It can also be sent via a mobile terminal connected to the dryer. The control unit receives the mixed drying signal and responds promptly.

[0153] In some embodiments of this application, the first valve may have three operating states: a first operating state, a second operating state, and a third operating state. Please continue reading. Figure 1 As shown, the third working state is the adjustment state, i.e., the partially open state. When the first working state is fully open, the second working state is fully closed. When the first working state is fully closed, the second working state is fully open.

[0154] In response to the mixing and drying signal, the fan and compressor can be started in the same manner as in the above embodiments, and will not be described in detail here.

[0155] In response to the mixed drying signal, the first valve is controlled to be in the third working state, which connects the bottom air duct to the first rear air duct and the second rear air duct respectively, enabling simultaneous drying of clothes and shoes and socks.

[0156] In some embodiments of this application, the opening degree of the first valve can be determined based on the quantity of shoes, socks, and clothing. If the quantity of shoes and socks is small but the quantity of clothing is large, the first valve can be controlled to move towards the second rear air duct so that a large amount of hot air can flow more fully into the drum, thereby ensuring the drying rate of the clothing.

[0157] Similarly, the opening degree of the first valve can be determined based on the weight of the shoes, socks, and clothes. If the shoes and socks are light but the clothes are heavy, the first valve can be moved towards the second rear air duct to allow a larger amount of hot air to flow more fully into the drum, thereby ensuring the drying rate of the clothes.

[0158] In other embodiments of this application, the opening degree of the first valve can also be determined by combining the quantity and weight of shoes, socks, and clothing.

[0159] As can be seen from S310 above, the first valve is a regulating valve, which can regulate the opening of air flowing from the bottom air duct into the first rear air duct, and regulate the opening of air flowing from the bottom air duct into the second rear air duct; in response to the mixed drying signal, the fan and compressor are started, and the first valve is controlled to be in the third working state, so that the bottom air duct can be connected to the first rear air duct and the second rear air duct respectively, so as to dry clothes and shoes and socks simultaneously, thereby realizing the function of simultaneous drying of clothes and shoes and socks.

[0160] In some embodiments of this application, the control unit may be electrically connected to the fan, the compressor, the first valve, and the second valve, respectively.

[0161] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure provided in response to clothes drying, as shown in another exemplary embodiment of this application.

[0162] In other embodiments of this application, the dryer further includes a second valve. The control unit can be configured to perform the following step S410:

[0163] S410, in response to the clothes drying signal, starts the fan and compressor, controls the first valve to the first working state, and closes the second valve to seal the passage between the top air duct and the front air duct.

[0164] In S410, a second valve is also installed at the air outlet of the shoe and sock drying chamber. Closing the second valve can seal the passage between the top air duct and the front air duct. Opening the second valve can open the passage between the top air duct and the front air duct.

[0165] The second valve can be closed in response to a clothes drying signal. The second valve can be opened in response to a shoes and socks drying signal. The second valve can be opened in response to a mixed drying signal.

[0166] As shown in S410 above, a second valve is also installed at the air outlet of the shoe and sock drying chamber. The second valve is used to close or open the channel between the top air duct and the front air duct. When in response to the clothes drying signal, the fan and compressor are started, the first valve is controlled to be in the first working state, and the second valve is closed to close the channel between the top air duct and the front air duct. This can prevent the heat of the air in the drum from entering the shoe and sock drying chamber, thereby effectively ensuring the drying efficiency of the clothes.

[0167] Please see Figure 5 , Figure 5 This is a flowchart illustrating the steps that the control unit can execute, provided in an exemplary embodiment of this application.

[0168] In some embodiments of this application, a humidity sensor is provided at the air outlet of the shoe and sock drying chamber. The control unit can be configured to perform the following steps S510-S540:

[0169] S510 acquires the real-time humidity of the air outlet of the shoe and sock drying chamber, as monitored by the humidity sensor.

[0170] In S510, a humidity sensor is used to monitor the outlet humidity of the shoe and sock drying chamber in real time. The control unit can acquire the outlet humidity of the shoe and sock drying chamber as monitored in real time by the humidity sensor.

[0171] S520 determines whether the humidity of the air outlet of the shoe and sock drying chamber is below the preset humidity limit.

[0172] In S520, it can determine whether the humidity of the air outlet of the shoe and sock drying chamber is below the preset humidity limit. The preset humidity limit can be used as a preset value to determine whether the shoes and socks in the shoe and sock drying chamber have been dried.

[0173] S530: If the determination is yes, then control the shutdown of the heat pump system.

[0174] In S530, if it is determined that the humidity of the air outlet of the shoe and sock drying chamber is below the preset humidity limit, indicating that the shoes and socks in the shoe and sock drying chamber are already dried, the heat pump system can be shut down.

[0175] If the judgment is negative in S540, then the control jumps to execute S510.

[0176] In S540, if it is determined that the humidity of the air outlet of the shoe and sock drying chamber is not below the preset humidity limit, indicating that the shoes and socks in the shoe and sock drying chamber are not completely dried, then it can be controlled to jump to execute S510.

[0177] As shown in S510-S540 above, a humidity sensor is installed at the air outlet of the shoe and sock drying chamber. The humidity sensor can monitor the air humidity of the shoe and sock drying chamber in real time. When the air humidity of the shoe and sock drying chamber is detected to be below the preset humidity limit, it indicates that the shoes and socks are dried. Then, the heat pump system is turned off to accurately control and stop drying, preventing the shoes and socks from being over-dried or under-dried.

[0178] Please see Figure 6 , Figure 6 This is a flowchart illustrating the steps that the control unit can execute, provided in another exemplary embodiment of this application.

[0179] In some embodiments of this application, the first valve is a regulating valve. A temperature sensor is provided at the air outlet of the shoe and sock drying chamber. The control unit can be configured to perform the following steps S610-S650:

[0180] S610, after shutting down the heat pump system, controls the fan to start and controls the first valve to be in the third working state, so that the bottom air duct is connected to the first rear air duct and the second rear air duct respectively.

[0181] In S610, after the heat pump system is shut down, the fan can be turned on. After the heat pump system is shut down, the first valve can be controlled to enter the third operating state, so that the bottom air duct is connected to the first rear air duct and the second rear air duct respectively.

[0182] S620 acquires the outlet air temperature of the shoe and sock drying chamber as monitored by the temperature sensor.

[0183] In the S620, a temperature sensor is used to monitor the outlet air temperature of the shoe and sock drying chamber in real time. The control unit can acquire the outlet air temperature of the shoe and sock drying chamber as monitored in real time by the temperature sensor.

[0184] S630 determines whether the outlet air temperature of the shoe and sock drying chamber has dropped below the preset temperature limit.

[0185] In S630, it can determine whether the outlet air temperature of the shoe and sock drying chamber is below a preset temperature limit. The preset temperature limit can be used as a preset value to determine whether the shoes and socks in the shoe and sock drying chamber are sufficiently cooled.

[0186] S640 If the judgment is yes, then control the dryer to stop running.

[0187] In S640, if it is determined that the outlet temperature of the shoe and sock drying chamber has dropped below the preset temperature limit, indicating that the shoes and socks in the shoe and sock drying chamber are in a sufficiently cooled state, the dryer can be controlled to stop operating.

[0188] If the determination is negative in S650, then the control jumps to execute S620.

[0189] In S650, if it is determined that the outlet temperature of the shoe and sock drying chamber has not dropped below the preset temperature limit, indicating that the shoes and socks in the shoe and sock drying chamber are not sufficiently cooled, then the control jumps to execute S620.

[0190] As shown in S610-650 above, the first valve is a regulating valve. A temperature sensor is also installed at the air outlet of the shoe and sock drying chamber. The temperature sensor can monitor the air outlet temperature of the shoe and sock drying chamber in real time. After the heat pump system is turned off, the fan is turned on and the first valve is controlled to be in the third working state, so that the bottom air duct is connected to the first rear air duct and the second rear air duct respectively. Through the bottom air duct being connected to the first rear air duct and the second rear air duct respectively, the hot air in the shoe and sock drying chamber can be better dissipated into the drum, thereby improving the cooling speed of the shoes and socks.

[0191] In addition, when the air outlet temperature of the shoe and sock drying chamber drops below the preset temperature limit, indicating that the shoes and socks are already cooled, the dryer is controlled to stop running, thus accurately controlling the cooling process and preventing energy waste.
