[0033] Clothes processing equipment, such as integrated washing and drying machines, clothes dryers and other clothes drying equipment with clothes drying functions, have been recognized by consumers for their advantages of low energy consumption, less wear and tear, and long life, and their market share is increasing. In the related art, the clothes processing equipment determines the dry state of clothes based on a capacitive humidity sensor. If there are fewer clothes or the total volume of clothes is small, it is difficult for the clothes to contact the electrode components of the capacitive humidity sensor during the rotation of the drum 23, resulting in low detection accuracy of the capacitive humidity sensor.

[0034] The utility model provides a clothing processing device, aiming to solve the technical problem of how to improve the detection accuracy of a humidity sensing capacitor module.

[0035] In the embodiment of the present utility model, Figure 1 As shown, Figure 1 The figure is a simplified structural diagram of an embodiment of the clothes processing device of the present utility model. The clothing processing device comprises: a housing 10, wherein the housing 10 is formed with an installation cavity 11; a drum assembly, wherein the drum assembly comprises a support member 21, a support shaft 22 and a drum 23, wherein the support member 21 is installed in the installation cavity 11, and the drum 23 is rotatably installed on the support member 21 through the support shaft 22; a humidity sensing capacitor module, wherein the humidity sensing capacitor module comprises a first electrode member 31 installed in the drum 23 and a dielectric, wherein the clothing holding cavity of the drum 23 forms a part of the dielectric; a position detection module, wherein the position detection module is installed in the installation cavity 11 and is used to detect the position of the first electrode member 31; a processing control module, wherein the processing control module is used to obtain a capacitance parameter of the humidity sensing capacitor module and obtain clothing dryness information in the drum 23 according to the capacitance parameter of the humidity sensing capacitor module; and the processing control module is electrically connected to the position detection module to control the drum 23 to rotate in the opposite direction or stay for a preset time when the first electrode member 31 moves to a preset position, wherein the preset position is located below the rotation axis of the drum 23.

[0036] In this embodiment, the housing 10 is used to form the overall appearance structure of the clothing processing device. The housing 10 is provided with an installation cavity 11, and the installation cavity 11 is used for installing the parts of the clothing processing device. The drum 23 is used to carry the clothes, and the drum 23 can rotate in the housing 10 to achieve the turning of the clothes. Among them, the support member 21 can be a bracket, a support tray or an outer cylinder, the support member 21 is fixed in the installation cavity 11, the support shaft 22 can be rotatably connected to the support member 21, and the bottom of the drum 23 is connected to the support shaft 22. The support member 21 can be located below the drum 23, and can also be located on one side of the drum 23, which is not limited here. The driving method of the drum 23 can be to drive the support shaft 22 to rotate to drive the drum 23 to rotate, or it can be to directly drive the drum 23 to rotate.

[0037] The housing 10 is provided with a take-in and put-out opening communicating with the installation cavity 11. The take-in and put-out opening may be provided at the top of the housing 10 or at a side wall of the housing 10 in the lateral direction, and no limitation is made here. The drum mouth of the drum 23 faces the take-in and put-out opening, and the user may put clothes into the drum 23 or take them out of the drum 23 through the take-in and put-out opening. The clothing processing device may further include a door cover, and the specific form and activity mode of the door cover are not limited, as long as the take-in and put-out opening can be opened or closed. It is understood that when the clothing processing device is working, the door cover will close the take-in and put-out opening to prevent the clothes from being thrown out of the drum 23.

[0038] The housing 10 is provided with an air inlet duct and an air outlet duct connected to the drum 23. The air inlet duct and the air outlet duct may be connected to each other outside the drum 23, or may be connected to the external environment of the housing 10. If the air inlet duct and the air outlet duct are connected to the external environment of the housing 10, then the air entering the drum 23 each time is external air, and the air discharged from the drum 23 is also discharged to the outside of the housing 10.

[0039] The air inlet duct may be provided with a heating device to heat the air in the air inlet duct so that the hot air can flow into the drum 23 to evaporate the moisture on the wet clothes. The heating device may be an electric heating wire or a heat pump assembly, which is not limited here, as long as the heating device can heat the air in the air inlet duct. For example, the heating device includes a heat pump assembly, which includes a compressor, a condenser and an evaporator, and the compressor, the condenser and the evaporator are connected in pairs through a refrigerant pipe; the condenser is installed in the air inlet duct to heat the air flowing to the drum 23. The evaporator can be installed in the air outlet duct to cool the hot and humid air flowing out of the drum 23.

[0040] The condenser is installed upstream of the air flow of the drum 23, and the evaporator is installed downstream of the air flow of the drum 23. When the heat pump system is working, the compressor drives the refrigerant to flow through the condenser and the evaporator in turn, and then flows back to the compressor; the refrigerant releases heat when flowing through the condenser, and evaporates and absorbs heat in the evaporator when flowing through the evaporator. The condenser can heat the air flowing to the drum 23, and the hot air enters the drum 23 and contacts the clothes, which can quickly evaporate the moisture on the clothes. After the moisture on the clothes is evaporated, it forms water vapor and mixes with the air flow to form humid hot air and flows out of the drum 23 together. The temperature of the evaporator is relatively low, and the humid hot air flowing out of the drum 23 can be dehydrated and dehumidified.

[0041] Specifically, the clothes processing device may further include a gas driving device, which is connected to the air inlet duct to drive the air flow along the air inlet duct to flow toward the drum 23. The gas driving device may be a fan or an air pump, which is not limited here.

[0042] In practical applications, one end of the air inlet duct away from the drum 23 is connected to one end of the air outlet duct away from the drum 23 to form a return duct. The gas driving device, evaporator and condenser are all installed in the return duct, and the gas driving device is located upstream of the evaporator, so that the airflow can be periodically heated, heat exchanged, dehydrated and dehumidified between the return duct and the drum 23.

[0043] The clothes processing device can determine whether the clothes have been fully dried by detecting the clothes dryness information in the drum 23. If the clothes have been dried, the clothes processing device can stop running in time to achieve energy saving and emission reduction. The humidity in the drum 23 will affect the capacitance parameter. Therefore, by detecting the capacitance parameter in the drum 23, the humidity in the drum 23 can be reflected, and specifically the humidity inside the clothes can be reflected, so that the clothes processing device can obtain the drying information of the clothes more realistically and reliably.

[0044] The humidity sensing capacitor module at least includes a first electrode member 31 , and may be composed of two first electrode members 31 , or may be composed of the first electrode member 31 and other charged structures, which is not limited here.

[0045] Specifically, Figure 1 As shown, the clothing processing device further includes a lifter 50, which is mounted on the inner circumferential wall of the drum 23; the first electrode member 31 is mounted on the lifter 50. The lifter 50 is used to lift the clothing to a high position during the rotation of the drum 23, and then the clothing is dropped from the high position to the bottom of the drum 23, so that the clothing can be dispersed along the axial direction of the drum 23, and the clothing can be prevented from being piled up and entangled, so that the clothing can be fully and evenly contacted with the hot air flow, thereby improving the drying effect of the clothing. The lifter 50 provides an installation space for the first electrode member 31, thereby reducing the occupation of the internal space of the drum 23 by the first electrode member 31, and the structural strength of the lifter 50 is higher, which can improve the installation stability of the electrode member.

[0046] In one embodiment, the humidity sensing capacitor module also includes the roller 23 as the second electrode member. By energizing the first electrode member 31 and the roller 23, an electric field can be formed between the first electrode member 31 and the roller 23. In this way, the roller 23 can be effectively utilized to simplify the composition of the humidity sensing capacitor module.

[0047] In another embodiment, the number of the lifters 50 is at least two, at least two of the lifters 50 are arranged at intervals along the circumference of the drum 23, at least two adjacent lifters 50 are installed with the first electrode member 31, and the humidity sensing capacitor module includes the first electrode member 31 on the two adjacent lifters 50. By energizing the electrode members on the two adjacent lifters 50, an electric field can be formed between the electrode members on the two adjacent lifters 50.

[0048] The processing control module may include a main control module and a sub-control module, the sub-control module is electrically connected to the humidity sensing capacitor module, the main control module is electrically connected to the position detection module and the driving mechanism of the drum 23, and the main control module may also obtain the clothing dryness information from the sub-control module. The position detection module may detect the position of the first electrode member 31. When the first electrode member 31 rotates to a preset position below the rotation axis of the drum 23, it indicates that the first electrode member 31 is at a lower position relative to the rotation axis at this time; after receiving the position signal, the main control module may control the drum 23 to switch the rotation direction or stay for a preset time at this position, so that the first electrode member 31 can be paused at the lower position, and the clothing falls to the preset position due to the loss of centrifugal force, so that the clothing can contact the first electrode member 31 during the pause period of the first electrode member 31, so that the clothing can be stably in the effective detection range of the humidity sensing capacitor module at least part of the time, thereby improving the humidity detection accuracy of the humidity sensing capacitor module for the clothing.

[0049] The position detection module may be a Hall sensor, a laser sensor or an infrared sensor, which is not limited here.

[0050] For example, Figure 1 As shown, the position detection module includes a position sensor 41 and a position feedback member 42 . The position sensor 41 is installed in the installation cavity 11 . The first electrode member 31 and the position feedback member 42 are installed on the same lifter 50 . The position sensor 41 is used to detect the position of the position feedback member 42 .

[0051] By detecting the position of the position feedback member 42 through the position sensor 41 to indirectly detect the position of the first electrode member 31, the accuracy of the position detection result of the first electrode member 31 can be improved, so that the position detection module can generate a position signal more quickly when the first electrode member 31 reaches the preset position, so as to improve the detection sensitivity, so that the roller 23 can switch the rotation direction or stop in time when the first electrode member 31 reaches the preset position.

[0052] The position sensor 41 may be installed below the drum 23 or on one side of the drum 23 .

[0053] Specifically, Figure 1As shown, the position sensor 41 is located below the roller 23, so that it can be ensured that the position sensor 41 is located below the rotation axis of the roller 23. When the position feedback member 42 enters the detection range of the position sensor 41, it indicates that the position feedback member 42 and the first electrode member 31 have reached the position below the rotation axis, thereby further improving the accuracy of the position detection structure of the first electrode member 31.

[0054] The preset location may be a single specific location or an interval range including multiple specific locations.

[0055] Exemplarily, the lifter 50 has a lowest position in the drum 23, and the lowest position is located directly below the rotation axis of the drum 23. The preset position includes a first critical position, a second critical position, and a preset interval between the first critical position and the second critical position, and the first critical position and the second critical position are respectively arranged on both sides of the lowest position.

[0056] The lowest position, the first critical position and the second critical position are all specific positions, and the lowest position is within the preset interval. When the first electrode member 31 rotates downward from a higher position to the first critical position or the second critical position, the position sensor 41 may be triggered to detect a signal, and the processing control module controls the drum 23 to reverse or stop according to the detection signal. During the reaction time from the position sensor 41 triggering the detection signal to the drum 23 reversing or stopping, the first electrode member 31 will continue to rotate in the original rotation direction. Therefore, setting the preset position to an interval range including the lowest position can ensure that the first electrode member 31 is always below the rotation axis during the reaction time of the drum 23, thereby ensuring that the first electrode member 31 can stay at a lower position to contact the dropped clothes.

[0057] The number of the position sensor 41 may be one, or may be two or more.

[0058] In one embodiment, if Figure 2 As shown, Figure 2 The figure is a schematic diagram of the position of the drum 23 and the position detection module in an embodiment of the present utility model. The position sensor 41 is arranged directly below the lowest position, and the position sensor 41 is used to generate a feedback signal when the position feedback member 42 enters the preset interval through the first critical position or the second critical position. The position sensor 41 can detect the interval range from the first critical position to the second critical position, thereby reducing the number of position sensors 41 to simplify the structure of the clothing processing device.

[0059] In another embodiment, if Figure 3 As shown, Figure 3The schematic diagram of the position of the roller 23 and the position detection module of another embodiment of the present utility model. The position sensor 41 includes a first sensor 411 and a second sensor 412. The first sensor 411 is used to generate a feedback signal when the position feedback member 42 enters the preset interval through the first critical position. The second sensor 412 is used to generate a feedback signal when the position feedback member 42 enters the preset interval through the second critical position. By detecting the two interval ranges respectively by the first sensor 411 and the sensor, the accuracy of the detection result can be improved.

[0060] For example, Figure 1 As shown, the clothing processing device also includes a wireless power supply module, which includes a wireless transmitting unit 61 and a wireless receiving unit 62. The wireless receiving unit 62 is installed on the support shaft 22 to rotate with the support shaft 22. The wireless transmitting unit 61 is installed in the installation cavity 11 and is close to the wireless receiving unit 62. The wireless receiving unit 62 is electrically connected to the humidity sensing capacitor module and the processing control module.

[0061] The wireless power supply module is used to directly provide current to the first electrode member 31 so that the humidity sensing capacitor module generates an electric field. Among them, the wireless transmitting unit 61 and the wireless receiving unit 62 are not in contact and are not connected by a conductor. The wireless transmitting unit 61 converts the electrical energy into an energy state corresponding to the field, which is received and converted back into electrical energy by the wireless receiving unit 62 after spatial transmission, and the wireless receiving unit 62 then transmits the electrical energy to the humidity sensing capacitor module. The wireless transmitting unit 61 may transmit an electric field, a magnetic field or an electromagnetic wave to the wireless receiving unit 62.

[0062] Since the wireless receiving unit 62 and the first electrode member 31 rotate with the drum 23, the wire between the wireless receiving unit 62 and the first electrode member 31 can also rotate with the drum 23, which will not affect the electrical conduction state between the wireless receiving unit 62 and the first electrode member 31. The wireless transmitting unit 61 needs to be electrically connected to the power supply to convert the transmitted power, and the wireless transmitting unit 61 is stationary in the housing 10, so the electrical conduction state between it and the power supply will not be affected. In this way, the convenience of power supply to the humidity sensing capacitor module and the stability of the power supply process can be improved.

[0063] It should be noted that if Figure 4 As shown, Figure 4 The schematic diagram of the structure of the wireless power supply module and the position detection module in the utility model is shown in FIG. The sub-control module is electrically connected to the wireless receiving module. Since the position sensor 41 is installed outside the drum 23 and does not rotate with the drum 23, the position sensor 41 does not need to be powered by the wireless power supply module, but only needs to be electrically connected to the main control module housing 10.

[0064] Specifically, the clothing processing equipment may also include a wireless transmission module, which includes a wireless signal transmitting terminal 71 and a wireless signal receiving terminal 72. The wireless signal transmitting terminal 71 is connected to the wireless receiving unit 62 and is electrically connected to the processing control module, and the wireless signal receiving terminal 72 is connected to the wireless transmitting unit 61.

[0065] The wireless signal transmitting terminal 71 and the wireless signal receiving terminal 72 can be an infrared transmitting terminal 71 and an infrared receiving terminal 72 respectively, or they can be other forms of signal transmission modules. When the clothing drying information obtained by the processing control module reaches the preset parameters, the processing control module can trigger the wireless signal transmitting terminal 71 to send a drying confirmation signal to the wireless signal receiving terminal 72. The wireless signal receiving terminal 72 is electrically connected to the main control terminal of the clothing processing device, and the main control terminal controls the clothing processing device to stop running according to the signal. The wireless receiving unit 62 and the wireless signal transmitting terminal 71 can be integrated together to form a first wireless transmission module, and the wireless transmitting unit 61 and the wireless signal receiving terminal 72 can be integrated together to form a second wireless transmission module. In this way, the installation process of the wireless power supply module and the wireless transmission module can be simplified at the same time, and the power supply of the wireless transmission module can be made simpler and more convenient.

[0066] In practical applications, such as Figure 1 As shown, an air cavity 24 is formed between the drum 23 and the support member 21, the drum 23 is provided with an air inlet 231, and the support member 21 is provided with an air inlet 211, and the air cavity 24 connects the air inlet 231 with the air inlet 211; the end of the support shaft 22 away from the drum 23 passes through the side of the support member 21 away from the drum 23, the wireless receiving unit 62 is installed at the end of the support shaft 22 away from the drum 23, and the wireless transmitting unit 61 is arranged on the side of the support member 21 away from the drum 23.

[0067] The air inlet 231 is provided at the bottom of the drum 23, and the support member 21 is in the shape of an outer cylinder or a support tray, so that an air cavity 24 is formed between the support member 21 and the bottom of the drum 23. In combination with the above-mentioned embodiment of the air inlet duct, the air inlet duct is connected with the air inlet 211. During the operation of the clothing processing device, the hot air flow first flows into the air cavity 24 from the air inlet 211, and then flows into the drum 23 from the air inlet 231. Therefore, the hot air flow will increase the temperature in the air cavity 24. The wireless receiving unit 62 is installed at one end of the support shaft 22 away from the drum 23 and passing through the bracket, that is, the wireless receiving unit 62 and the wireless transmitting unit 61 are both installed outside the air cavity 24. In this way, the wireless transmitting unit 61 and the wireless receiving unit 62 can be prevented from being affected by the high temperature in the air cavity 24, so as to improve the working stability of the wireless power supply module.

[0068] The wireless transmitting unit 61 can be installed on the housing 10, or on the supporting member 21, or on other structures that are stationary relative to the drum 23, and there is no limitation here.

[0069] In one embodiment, if Figure 1 As shown, the wireless receiving unit 32 is arranged around the support shaft 22, and the wireless transmitting unit 61 is installed on the housing 10 and is axially opposite to the end of the support shaft 22. The wireless receiving unit 62 can be a ring coil, and the wireless transmitting unit 61 can be a disc coil, so that the wireless receiving unit 62 and the wireless transmitting unit 61 can maintain a sufficient facing area to ensure the power transmission efficiency.

[0070] In another embodiment, the wireless receiving unit 62 is annularly arranged on the support shaft 22, and the wireless transmitting unit 61 is installed on the support member 21 and extends along the circumference of the support shaft 22. The wireless receiving unit 62 and the wireless transmitting unit 61 are both annular coils, and a gap is formed between the inner circumference of the wireless transmitting unit 61 and the circumferential wall of the support shaft 22. The wireless power supply module is installed on the drum assembly, so that the overall structure formed by the wireless power supply module and the drum assembly can be more compact.

[0071] In yet another embodiment, Figure 5 As shown, Figure 5 This is a simplified structural diagram of another embodiment of the clothing processing device of the utility model. The clothing processing device also includes a protective cover 70, and the protective cover 70 covers the wireless power supply module. The wireless receiving unit 62 is arranged around the support shaft 21, and the wireless transmitting unit 61 is installed on the inner wall of the protective cover 70. The protective cover 70 can protect the wireless power supply module. The protective cover 70 also has a heat insulation function, which can reduce the impact of the thermal environment around the wireless power supply module on the wireless power supply module. In addition, the protective cover 70 can also provide an installation basis for the wireless transmitting unit 61 to simplify the installation method of the wireless transmitting unit 61.
