[0002] Currently available clothes drying devices, such as dryers and washer-dryers, mainly adopt condensation cycle drying. The principle is generally to heat the air through a heater and enter the drying drum. Under the action of the hot air, the water on the clothes evaporates and forms humid hot air with the air. The humid hot air then enters the condenser. The humid hot air is condensed into condensed water and dry gas after being acted upon by a cooling medium in the condenser. The dry gas is then heated by the heater and enters the drum. After this cycle, the purpose of drying the clothes is achieved. However, the use of air circulation has problems such as strong odor, high temperature, and large amount of condensation water. In addition, the circulation temperature is high, which causes damage to the clothes. Therefore, it is necessary to optimize the existing clothes drying device and adopt a direct discharge method.

[0003] The direct exhaust method of the prior art introduces fresh air from the outside and directly discharges it from the dryer after drying.

It should be understood that the terms such as "having", "including" and "comprising" used herein do not specify the existence or addition of one or more other elements or their combinations.

[0034] like Figure 1-Figure 3 As shown, an air intake module 20 of a clothes drying device provided by the present invention includes: a box body, a damper 23, a driving member 25, and a negative ion generator.

[0035] The box body includes a bottom box 21 and an upper cover 22, and the upper cover 22 is buckled with the bottom box 21. Preferably, a lower buckle part is provided on the bottom box 21, and an upper buckle part is provided on the upper cover 22, and the upper buckle part and the lower buckle part are buckled and sealed.

[0036] The bottom box 21 of the box body is provided with an air inlet 2121 and an air outlet 2111; the damper 23 is installed on the bottom box 21 of the box body; the air inlet 2121 and the air outlet 2111 are located on both sides of the damper 23. When the damper 23 is in the open state, the air inlet 2121 and the air outlet 2111 are connected.

[0037] The air inlet 2121 is connected to the fresh air outside the device, and the air outlet 2111 is connected to the inner drum of the clothes drying device.

[0038] The bottom box 21 includes a first area 2110 and a second area 2120. The bottom box 21 is provided with a partition 2130. A vent 2131 is provided on the partition 2130, that is, a vent 2131 is provided between the first area 2110 and the second area 2120. An openable and closable damper 23 is installed in the second area 2120. The damper 23 seals and covers the vent 2131 when in a closed state.

[0039] Preferably, the air inlet 2121 is located in the second area 2120, the air outlet 2111 is located in the first area 2110, and the damper 23 is located in the second area 2120, that is, close to the air inlet 2121. The first area 2110 is connected to a negative ion generator (not shown in the figure) through a pipeline, and the negative ions generated by the negative ion generator remove dust and purify the air in the first area 2110.

[0040] A negative ion generator is a device that generates negative air ions. The device processes the input DC or AC power through an EMI processing circuit and a lightning protection circuit, and then upgrades it to AC high voltage through a pulse circuit, overvoltage current limiting, high and low voltage isolation and other lines. The device then rectifies and filters it through special grade electronic materials to obtain pure DC negative high voltage. The DC negative high voltage is connected to a release tip made of metal or carbon elements, and the DC high voltage at the tip is used to generate high corona, releasing a large number of electrons at a high speed. Electrons cannot exist in the air for a long time and will be immediately captured by oxygen molecules in the air, thereby generating negative air ions.

[0041] The damper 23 includes a damper body 231 , a sealing ring 232 , and a mounting shaft 233 .

[0042] The damper body 231, the sealing ring 232, and the mounting shaft 233 may be integrally formed. Alternatively, the damper body 231 and the mounting shaft 233 may be integrally formed, and the sealing ring 232 may be fixedly mounted on the damper body 231. Preferably, the sealing ring 232 is a flexible material that can achieve sealing. The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131.

[0043] The sealing ring 232 is located on the side of the damper body 231 facing the vent 2131. Preferably, the damper is rotatably mounted on the box body, and the damper 23 opens toward the air inlet 2121. When the damper 23 is closed, the wind from the air inlet 2121 causes the damper body 231 and the sealing ring 232 to be tightly pressed against the partition 2130.

[0044] Preferably, a rotation hole is provided on the bottom box 21, and the mounting shaft 233 is rotatably mounted in the rotation hole, so that the damper 23 is rotatably mounted on the bottom box 21. Preferably, the damper 23 rotates in the direction of the air inlet, that is, the damper opens in the direction of the air inlet 2121. When the damper 23 is closed, the fresh air entering from the air inlet 2121 can exert pressure on the damper body 231, so that the damper body 231 squeezes the sealing ring 232 to achieve sealing of the damper, ensuring that when the damper is closed, no air will enter the air inlet module.

[0045] The driving member 25 is fixedly mounted on the box body. Preferably, the driving member 25 is fixedly mounted on the outer wall of the bottom box 21. The damper 23 is power-coupled with the driving member 25. In this embodiment, the driving member 25 drives the mounting shaft 233 of the damper 23 to rotate in the mounting hole to realize the opening and closing of the damper 23.

[0046] In other embodiments, the damper is installed on the box body, and the damper can achieve linear displacement on the box body to open the vent 2131, and the driving member 25 drives the damper 23 to achieve linear motion.

[0047] The air inlet module 20 also includes a sensor, which is used to detect the position of the damper. When the damper is detected to be in the open position, the negative ion generator starts to work.

[0048] The air inlet module 20 further includes an angle detection device, which is used to obtain the opening and closing angle of the damper body.

[0049] The angle detection device includes: a magnet mounted on the mounting shaft 233 and a Hall sensor facing the magnet.

[0050] The magnet installed on the installation shaft 233 rotates along with the installation shaft 233, and the magnetic field of the magnet along the installation shaft 233 changes with the rotation of the magnet;

[0051] The Hall sensor opposite to the magnet can detect the opening and closing angle of the damper body 231 according to the change of the magnetic field.

[0052] The magnet rotates with the damper, and its magnetic field along the main shaft direction also changes with the rotation. The Hall sensor detects the opening and closing angle of the damper body 231 according to the change of the magnetic field, and can detect the opening and closing angle quickly, accurately and efficiently.

[0053] The Hall sensor is an angle Hall sensor. The angle Hall sensor detects the opening and closing angle of the damper according to the change of the magnetic field. Specifically, the angle Hall sensor converts the spatial position change of the N and S magnetic fields of the magnet into the angle change of the main shaft body, and outputs the angle change in the form of digital quantity to the main control unit.

[0054] Among them, when the opening and closing angle of the damper body is greater than the angle threshold, the negative ion generator works. It can be understood that the negative ion generator can only work when the damper body is opened and closed to a certain angle, laying the foundation for the subsequent realization of automatic control.

[0055] The air intake module 20 provided by the present invention is installed in the clothes washing and drying device 100, and can drive the damper 23 to open to achieve the connection between the air inlet 2121 and the air outlet 2111; and the size of the opening of the damper driven by the driving member 25 can be controlled according to demand; the negative ions generated by the negative ion generator remove dust and purify the air in the first area 2110, thereby ensuring the hygiene of the clothes in the clothes washing and drying device 100; and the negative ion generator can work when the damper 23 is opened, without causing waste of energy.

[0056] The present invention provides an air intake module. When fresh air is not needed, the damper 23 in the air intake module can be closed. At the same time, when the damper is closed, the problem of laundry foam overflowing from the air intake duct 1 can be effectively prevented.

[0057] Accordingly, the present invention also provides a clothes washing and drying device 100, see Figure 4-Figure 5 , a box body, constituting the basic external structure of the device; an inner drum 3 and an outer drum arranged in the box body, the inner drum 3 is used to hold the dried clothes; an air inlet duct 1 connected to the external fresh air; a connecting duct 6 connected to the inner drum, and an air inlet module 20 as described above. The air inlet duct 1 is connected to the air inlet 2121 of the air inlet module 20, and the connecting duct 6 connects the air outlet 2111 of the air inlet module 20 with the inner drum 3.

[0058] The external fresh air enters the second area 2120 of the damper structure 20 through the air inlet duct 1, and the damper 23 is opened, and the fresh air enters the first area 2110 through the vent 2131. After the negative ions generated by the negative ion generator purify the air in the first area 2110, the fresh air enters the connecting duct 6 from the air outlet 2111, and then enters the inner cylinder 3. When the damper is closed, the fresh air entering from the air inlet 2121 can exert pressure on the damper body 231, so that the damper body 231 squeezes the sealing ring 232 to achieve sealing of the damper, ensuring that the air inlet module does not pass air.

[0059] Preferably, the clothes drying device includes a fresh air system, which includes an air inlet duct 1 and an exhaust duct 2. The air inlet 2121 of the damper structure 20 of the air inlet duct 1 and the air outlet 2111 of the damper structure 20 are connected to the inner drum 3, and are used to pass the air outside the device into the inner drum 3 after passing through the damper structure 20; the exhaust duct 2 is connected to the inner drum 3, and the heat exchange component 10 is arranged on the exhaust duct 2. The high-humidity and high-temperature air in the inner drum 3 is cooled by the heat exchange component 10 and then discharged from the drum to the room.

[0060] Preferably, the clothes drying device 100 also includes a condenser 4, which is connected to the outer drum. The hot and humid air in the inner drum 3 enters between the inner and outer drums through the holes on the inner drum 3, and enters the condenser 4 through the holes on the outer drum. The condenser 4 condenses the hot and humid air entering the condenser 4 from the outer drum. The other end of the condenser 4 is connected to the inner drum 3 so that the condensed air can be heated by the heating component 51 in the circulating air duct 5 under the action of the fan volute 52 and then supplied to the inner drum 3.

[0061] Preferably, the cooling medium outlet on the heat exchange component 10 is connected to the condenser 4, and the cooling water enters the condenser 4 after passing through the water channel structure of the air outlet module and is reused by the condenser 4. The utilization rate of water is improved, and at the same time, the heat exchange component 10 directly discharges moisture, so that the drying efficiency is increased and the drying time is shortened.

[0062] In some embodiments, the clothing drying device is a washing machine or a drying machine or a washer-dryer. When it is a washer-dryer, it has a corresponding structure and function for washing clothes, and a drum-type washer-dryer is more preferred.

[0064] The present invention provides an air intake module. When fresh air is not needed, the damper 23 in the air intake module can be closed. At the same time, when the damper is closed, the problem of laundry foam overflowing from the air intake duct 1 can be effectively prevented.

[0065] The air inlet module 20 provided by the present invention can also accurately and efficiently detect the opening and closing angle of the air door, laying a foundation for the subsequent realization of automatic control.
