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 dryness of clothes based on resistive humidity sensors, but resistive humidity sensors can only detect the humidity on the surface of clothes and cannot accurately detect the humidity inside clothes, causing the clothes processing equipment to judge the dryness information of clothes in the drum inaccurately, affecting the clothes drying effect.

The utility model provides a clothes processing device, aiming to solve the technical problem of how to improve the clothes drying effect of the clothes processing device.

In an embodiment of the present invention, as shown in FIG1 , FIG1 is a simplified cross-sectional view of an embodiment of a clothes processing device of the present invention.

The clothing processing device comprises: a housing 10, wherein the housing 10 is provided with an installation cavity 11; a drum 20, wherein the drum 20 is rotatably installed in the installation cavity 11 and comprises a clothing holding cavity; a lifter 30, wherein the lifter 30 is installed on the inner peripheral wall of the drum 20; a humidity sensing capacitor module, wherein the humidity sensing capacitor module comprises an electrode member 40 and a dielectric material installed on the lifter 30, wherein the clothing holding cavity of the drum 20 forms a part of the dielectric material; a processing control module 50, wherein the processing control module 50 is used to obtain a capacitance parameter of the humidity sensing capacitor module, and obtain clothing dryness information in the drum 20 according to the capacitance parameter of the humidity sensing capacitor module; and a power supply module 80, wherein the power supply module 80 is electrically connected to the humidity sensing capacitor module and the processing control module 50, and wherein the power supply module 80 is used to supply power to the humidity sensing capacitor module and the processing control module 50.

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 20 is used to carry the clothes, and the drum 20 can rotate in the housing 10 to realize the turning of the clothes. Specifically, it can be a partial structure rotation or a full rotation. The housing 10 is provided with a take-in and put-out port connected to the installation cavity 11. The take-in and put-out port can be opened at the top of the housing 10, or it can be opened on a side wall of the housing 10 in the horizontal direction, and there is no restriction here. The barrel mouth of the drum 20 faces the take-in and put-out port, and the user can put the clothes into the drum 20 or take them out of the drum 20 through the take-in and put-out port. The clothing processing device may also include a door cover 60, and the specific form and activity mode of the door cover 60 are not limited, as long as the take-in and put-out port can be opened or closed. It can be understood that when the clothing processing device is working, the door cover 60 will close the take-in and put-out port to prevent the clothes from being thrown out of the drum 20.

The housing 10 is provided with an air inlet duct and an air outlet duct connected to the drum 20. The air inlet duct and the air outlet duct may be connected to each other outside the drum 20, 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 20 each time is external air, and the air discharged from the drum 20 is also discharged to the outside of the housing 10.

The heating device may be an electric heating wire or a heat pump assembly, and there is no limitation here. It only needs to satisfy that 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, wherein 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 2020. The evaporator can be installed in the air outlet duct to cool the hot and humid air flowing out of the drum 20.

The condenser is installed upstream of the air flow of the drum 20, and the evaporator is installed downstream of the air flow of the drum 20. 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 20, and the hot air enters the drum 20 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, which flows out of the drum 20 together. The temperature of the evaporator is relatively low, and the humid hot air flowing out of the drum 20 can be dehydrated and dehumidified.

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 20. The gas driving device may be a fan or an air pump, which is not limited here.

In practical applications, one end of the air inlet duct away from the drum 20 is connected to one end of the air outlet duct away from the drum 20 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 20.

The lifter 30 is used to disperse the clothes along the axial direction of the drum 20 during the rotation of the drum 20 to prevent the clothes from piling up, so that the clothes can fully and evenly contact the hot air flow, thereby improving the drying effect of the clothes.

The clothes processing device can determine whether the clothes have been fully dried by detecting the clothes dryness information in the drum 20. 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 20 will affect the capacitance parameter. Therefore, by detecting the capacitance parameter in the drum 20, the humidity in the drum 20 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.

The lifter 30 provides installation space for the electrode member 40, thereby reducing the occupation of the internal space of the drum 20 by the electrode member 40, and the lifter 30 has a higher structural strength, which can improve the installation stability of the electrode member 40. The humidity sensing capacitor module at least includes the electrode member 40 installed on the lifter 30, and can be composed of two electrode members 40 to form a humidity sensing capacitor module, or it can be composed of the electrode member 40 and other charged structures to form a humidity sensing capacitor module, which is not limited here.

The power supply module 80 is used to directly provide current to the electrode member 40 and another charged structure that forms the humidity sensing capacitor module with the electrode member 40, so that the humidity sensing capacitor module generates an electric field. The power supply module 80 can be installed inside the drum 20 or outside the drum 20, and there is no limitation here; in this way, there is no need to consider the influence of the rotation of the drum 20 on the power supply process of the humidity sensing capacitor module and the processing control module 50.

The power supply module 80 is also used to power the information processing module. The information processing module can detect the capacitance parameters in the drum 20 through the humidity sensing capacitance module, and then process and convert them into clothing drying parameters or humidity parameters. If the obtained clothing drying parameters or humidity parameters reach the preset values, the information processing module will send a confirmation signal for clothing drying to the control end of the clothing processing device, so that the control end of the clothing processing device can control the clothing processing device to stop running according to the signal.

Since the information processing module obtains the capacitance parameters of the humidity sensing capacitor module, it will not be affected by the obstruction of clothing, so the humidity inside the clothing can also be effectively detected, making the detection result more real and reliable.

For example, as shown in FIG2 , FIG2 is a schematic cross-sectional view of an embodiment of the laundry processing device of the utility model. The electrode member 40 and the drum 20 are combined to form a first humidity sensing capacitor module 41, and the processing control module 50 is used to obtain the capacitance parameter between the electrode member 40 and the drum wall of the drum 20 through the first humidity sensing capacitor module 41.

The first humidity sensing capacitor module 41 is one of the humidity sensing capacitor modules including the electrode member 40. By energizing the electrode member 40 and the drum 20, an electric field can be formed between the electrode member 40 and the drum 20. In this way, the drum 20 can be effectively utilized to simplify the composition of the first humidity sensing capacitor module 41.

For example, as shown in FIG3 , FIG3 is a cross-sectional view of another embodiment of the laundry processing device of the utility model. The lifter 30 has a first side wall and a second side wall, and the first side wall and the second side wall are arranged opposite to each other along the circumference of the drum 20; the electrode member 40 includes a first electrode member 42 and a second electrode member 43, the first electrode member 42 is installed on the first side wall, and the second electrode member 43 is installed on the second side wall, and the first electrode member 42 and the second electrode member 43 are combined to form a second humidity sensing capacitor module 44, and the processing control module 50 is used to obtain the capacitance parameter between the first electrode member 42 and the second electrode member 43 through the second humidity sensing capacitor module 44.

The first side wall and the second side wall can be parallel to each other or can be inclined to each other, and there is no limitation here, as long as they are opposite to each other along the circumference of the drum 20. By energizing the first electrode member 42 and the second electrode member 43, an electric field can be formed between the first electrode member 42 and the second electrode member 43; thus, the electric field range of the second humidity sensing capacitor module 44 can be expanded, so that the detected capacitance parameters can more truly and accurately reflect the humidity information in the drum 20.

Exemplarily, as shown in FIG4 , FIG4 is a cross-sectional view of another embodiment of the laundry processing device of the utility model. The number of the lifters 30 is at least two, and at least two of the lifters 30 are arranged at intervals along the circumference of the drum 20, and at least two adjacent lifters 30 are installed with the electrode members 40, so that the electrode members 40 on the two adjacent lifters 30 are combined to form a third humidity sensing capacitor module 45, and the processing control module 50 is used to obtain the capacitance parameters between the two adjacent lifters 30 through the third humidity sensing capacitor module 45. By energizing the electrode members 40 on the two adjacent lifters 30, an electric field can be formed between the electrode members 40 on the two adjacent lifters 30.

Specifically, as shown in FIG. 4 , the lifter 30 has a first side wall and a second side wall, and the first side wall and the second side wall are arranged opposite to each other along the circumference of the drum 20; the electrode member 40 includes a first electrode member 42 and a second electrode member 43, and the first electrode member 42 is installed on the first side wall, and the second electrode member 43 is installed on the second side wall; the first electrode member 42 on each lifter 30 and the second electrode member 43 on the adjacent lifter 30 are combined to form the third humidity sensing capacitor module 45. In this way, the number of the third humidity sensing capacitor modules 45 can be increased to increase the detection positions of the capacitance parameters in the drum 20, so as to reflect the humidity information of multiple positions in the multi-drum 20, so as to make the final clothes drying information more real and reliable.

Exemplarily, the lifter 30 extends in the depth direction of the drum 20, and the electrode member 40 extends in the length direction of the lifter 30; the electrode member 40 has a first end close to the bottom of the drum 20, and the distance between the first end and the bottom of the drum 20 does not exceed 100 mm. In this way, the first end of the electrode member 40 can be made as close to the bottom of the drum 20 as possible, thereby increasing the contact area between the clothes and the lifter 30, and increasing the range of the electric field formed by the humidity sensing capacitor module, so as to improve the sensing range of the humidity sensing capacitor module to the humidity of the clothes, thereby improving the reliability of the obtained clothing dryness information.

In another embodiment, the housing 10 is further provided with a take-in/put-out port connected to the installation cavity 11, and the clothing processing device further includes a door cover 60 for opening or closing the take-in/put-out port, and the electrode member 40 has a second end close to the barrel opening of the drum 20, and the distance between the second end and the door cover 60 does not exceed 100 mm. In this way, the second end of the electrode member 40 can be made as close to the barrel opening of the drum 20 as possible, thereby increasing the contact area between the clothing and the lifter 30, and increasing the range of the electric field formed by the humidity sensing capacitor module, further improving the sensing range of the humidity sensing capacitor module for clothing humidity, thereby further improving the reliability of the obtained clothing dryness information.

The power supply module 80 may be a battery or other forms of power supply structures.

For example, as shown in Figure 5, which is a cross-sectional diagram of another embodiment of the laundry processing device of the utility model, the power supply module 80 includes a power supply slip ring 70, which is installed on the rotating shaft of the drum 20, and the humidity sensing capacitor module is electrically connected to the processing control module 50 through the power supply slip ring 70.

The rotor of the power supply slip ring 70 can rotate with the rotating shaft of the drum 20, and the humidity sensing capacitor module and the processing control module 50 are both electrically connected to the rotor of the power supply slip ring 70, so that the humidity sensing capacitor module and the processing control module 50 can be powered during the rotation of the drum 20. The laundry dryness information obtained by the processing control module 50 can also be transmitted to the control end of the laundry processing device through the power supply slip ring 70.

In another embodiment, as shown in FIG. 1 , the power supply module 80 includes a magnetoelectric module 81 and an energy storage module 82 installed on the lifter 30 , and the energy storage module 82 is electrically connected to the magnetoelectric module 81 and the humidity sensing capacitor module.

The magnetoelectric module 81 can generate electric energy during the rotation of the drum 20, and the energy storage module 82 can store the electric energy generated by the magnetoelectric module 81 in time, and supply power in time when the humidity sensing capacitor module and the processing control module 50 are working. In this way, wireless power supply to the humidity sensing capacitor module and the processing control module 50 can be realized to simplify the power supply method.

Specifically, as shown in Figure 1, the clothing processing device also includes a wireless transmission module 83 installed on the lifter 30, and the wireless transmission module 83 is electrically connected to the energy storage module 82 and the processing control module 50. The wireless transmission module 83 is used to send a drying confirmation signal to the wireless receiving end 84 of the clothing processing device when the humidity in the drum 20 reaches a preset value.

The wireless transmission module 83 can be an infrared transmitter or a transmission module in other forms. When the clothes drying information obtained by the processing control module 50 reaches the preset parameters, the processing control module 50 can trigger the wireless transmission module 83 to send a confirmation drying signal to the wireless receiving end 84 of the clothes processing device, and the control end of the clothes processing device controls the clothes processing device to stop running according to the signal.

In practical applications, as shown in FIG1 , the lifter 30 is provided with a moving cavity, and the magnetoelectric module 81 is installed in the moving cavity and can move along the length direction of the moving cavity, and the length direction of the moving cavity is at an acute angle or an obtuse angle with the rotation axis of the drum 20. The magnetoelectric module 81 generates electric energy by reciprocating in the moving cavity, and the length direction of the moving cavity is set at an acute angle or an obtuse angle with the rotation axis of the drum 20, which can increase the movement stroke of the magnetoelectric module 81, thereby increasing the electric energy generated by the magnetoelectric module 81, so as to improve the power generation efficiency.

Exemplarily, as shown in FIG5 , the housing 10 is further provided with a take-in/take-out port communicating with the installation cavity 11, and the clothing processing device further includes a door cover 60 for opening or closing the take-in/take-out port, and the door cover 60 is provided with a protrusion 61 extending toward the inside of the drum 20 on one side thereof facing the drum 20, and the protrusion 61 is used to limit the clothing toward the direction close to the lifter 30. The protrusion 61 can limit the clothing at a position close to the lifter 30, so as to improve the detection effect of the humidity sensing capacitor module and the processing control module 50 on the internal capacitance parameters of the clothing.

Specifically, as shown in FIG. 5 , the housing 10 is further provided with a take-in/take-out port communicating with the installation cavity 11, and the clothing processing device further comprises a door cover 60 for opening or closing the take-in/take-out port; the humidity sensing capacitor module further comprises an electrode body 62 mounted on the door cover 60, and the electrode body 62 is combined with the electrode member 40 to form a fourth humidity sensing capacitor module 46, and the processing control module 50 is used to obtain the capacitance parameter between the lifter 30 and the door cover 60 through the fourth humidity sensing capacitor module 46. By energizing the electrode member 40 and the electrode body 62, an electric field can be formed between the door cover 60 and the lifter 30, so that the formation method of the fourth humidity sensing capacitor module 46 can be simplified.

In actual application, as shown in Fig. 1, Fig. 2 and Fig. 5, the clothing processing device further includes a resistive humidity sensor 90, which is mounted on the surface of the lifter 30 to detect the humidity of the clothing by contacting the clothing. The resistive humidity sensor 90 can directly detect the humidity on the surface of the clothing. The resistive humidity sensor 90 is used in combination with the humidity sensing capacitor module to detect the humidity on the surface of the clothing and the humidity inside the clothing, so as to comprehensively judge the dryness inside and outside the clothing, so as to improve the accuracy of judging the dryness of the clothing.

In combination with the above-mentioned embodiments of the first side wall and the second side wall, the resistive humidity sensor 90 can be installed between the first side wall and the second side wall, that is, installed on the side of the lifter 30 facing away from the wall of the drum 20, so that the resistive humidity sensor 90 can more easily contact the clothes to improve the reliability of the humidity detection process.
