[0031] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0032] See also Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a clothes dryer 1 provided in an embodiment of the present application. Figure 2 for Figure 1The schematic cross-sectional view of the clothes dryer 1 is obtained by cutting it at AA. The embodiment of the present application provides a clothes dryer 1, and the clothes dryer 1 can be a heat pump clothes dryer 1, or a condensing clothes dryer 1, and of course, an exhaust clothes dryer 1, which is not specifically limited in the present application. The clothes dryer 1 includes a housing 10, a barrel 20, a negative ion generator 30, and an electric adsorption device 40. The barrel 20 is installed in the housing 10, and a clothing receiving cavity 441 is provided in the barrel 20. The negative ion generator 30 is installed in the housing 10, and the negative ion generator 30 is used to release electrons into the clothing receiving cavity 441 to charge the debris in the clothing receiving cavity 441. The electric adsorption device 40 is installed in the housing 10, and the electric adsorption device 40 generates an electric field for adsorbing debris. The dryer 1 provided in the embodiment of the present application uses a negative ion generator 30 to release electrons into the clothing receiving cavity 441. The electrons combine with debris in the clothing receiving cavity 441 to charge the debris. An electric adsorption device 40 is used to generate an electric field, and the charged debris is adsorbed by the electric field to collect the debris. This can greatly reduce the content of debris attached to the clothes, effectively improving the wearing comfort of the clothes.

[0033] See also Figure 3 , Figure 3 This is a diagram of the internal structure of one side of the dryer 1 provided in an embodiment of the present application. The housing 10 includes a shell 11 and a base 12. Along the direction of gravity, at least a portion of the shell 11 is fixed to the base 12, and another portion is located above the base 12, which is used to define an assembly space for accommodating the barrel 20. The dryer 1 also includes a heating system 50 for heating the air in the clothing receiving chamber. The heating system 50, the negative ion generator 30, and the electric adsorption device 40 can be installed together on the base 12 to form an integrated fixed assembly, thereby effectively reducing the occupied space of the dryer 1 and facilitating the daily maintenance of the dryer 1.

[0034] See also Figure 4 , Figure 4The internal structure diagram of the other side of the clothes dryer 1 provided in the embodiment of the present application. The barrel 20 is provided with an air inlet 21, and the clothes dryer 1 may further include a first fan 60, which is installed on the box 10 and faces the air inlet 21 to form an air flow in the clothing receiving chamber 441. Exemplarily, the first fan 60 may be installed on the housing 11 or on the base 12, and the end of the barrel 20 or the barrel wall between the two ends of the barrel 20 may be provided with an air inlet 21 connected to the clothing receiving chamber 441, and the air outlet of the first fan 60 is arranged toward the air inlet 21 to form a turbulent air flow in the clothing receiving chamber 441. The turbulent air flow in the clothing receiving chamber 441 can not only accelerate the diffusion of heat and improve the drying speed, but also accelerate the diffusion of electrons and debris, so that the electrons and debris are fully in contact so that more debris is charged, so that the electric adsorption device 40 can collect more debris. In order to increase the wind force of the first fan 60, the dryer 1 may further include an air guide hood 70, which connects the first fan 60 and the air inlet 21, thereby concentrating the airflow generated by the first fan 60 and allowing the airflow generated by the first fan 60 to enter the clothing receiving chamber 441 only from the air inlet 21, which is beneficial to increasing the turbulence of the airflow and further allowing the electrons to fully contact the clothing, air, and debris in the barrel body 20.

[0035] Please combine Figure 2 See also Figure 4 In some embodiments, the barrel body 20 includes a barrel bottom and a barrel mouth 22 that are relatively arranged. The barrel bottom may be provided with an air inlet 21. The electric adsorption device 40 is arranged adjacent to the barrel mouth 22 and adsorbs charged debris from the barrel mouth 22. By arranging the air inlet 21 and the electric adsorption device 40 at both ends of the barrel body 20, the electrons generated by the negative ion generator 30 can have a longer travel in the barrel body 20, so that the electrons can fully contact the clothes, air, and debris suspended in the air in the barrel body 20, so that the clothes can be better sterilized and disinfected, and the debris can be fully collected. In some embodiments, the air inlet 21 may also include a plurality of first holes 210, and the electric adsorption device 40 is provided with a plurality of second holes 410 connected to the barrel mouth 22. Exemplarily, the plurality of first holes 210 and the plurality of second holes 410 may be in any suitable distribution form such as a matrix, a circumferential, or a honeycomb, so that the airflow passing through can be softer and more uniform.

[0036] See also Figure 2 and Figure 3The negative ion generator 30 includes a main body 31 and a delivery pipe 32 connected to the main body 31 . The main body 31 is used to generate electrons. The delivery pipe 32 is connected to the air inlet 21 so that the electrons enter the clothing receiving cavity 441 . The negative ion generator 30 can be an existing negative ion generator, which uses high-voltage corona to increase the negative ion content in the air. The negative ion generator 30 processes the input DC or AC power through an EMI (Electromagnetic Interference) 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, and then obtains a pure DC negative high voltage after rectification and filtering by special grade electronic materials. 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 a high corona to release a large number of electrons at a high speed. The electrons cannot exist in the air for a long time and will be immediately captured by oxygen molecules in the air, thereby generating air negative ions (also referred to as negative oxygen ions in some embodiments). Some of the negative ions come into contact with bacteria and viruses in clothing and air to reverse the internal and external potential polarity of the bacteria and viruses, thereby achieving the effect of sterilization and disinfection. Some of the negative ions attach to debris suspended in the air to make the debris negatively charged. The electric adsorption device 40 generates an electric field after power is turned on, which can collect the negatively charged debris.

The shell 41 is provided with the multiple second holes 410, and the collection unit 42 is provided with a collection groove 420. The multiple second holes 410 connect the collection groove 420 and the barrel mouth 22. The electric field generating unit 43 is provided on the side of the collection unit 42 away from the collection groove 420 to generate an electric field in the collection groove 420.

[0039] Exemplarily, the clothes dryer 1 further includes a positioning seat 80 for defining the barrel 20, the positioning seat 80 is fixed to the base 12, and the shell 41 may be at least a part of the positioning seat 80. Specifically, the shell 41 is provided with a through opening 411 connected to the installation space 430, and the through opening 411 is detachably covered with a mesh plate 412, and the mesh plate 412 is provided with the plurality of second holes 410 for connecting the clothing receiving cavity 441 and the collecting tank 420, and the collecting unit 42 may include a first plate 421 and a second plate 422 arranged at an angle, and a collecting tank 420 for accommodating debris is formed between the first plate 421 and the second plate 422, and the collecting tank 420 is arranged toward the mesh plate 412 so that the debris can fall into the bottom of the collecting tank 420 along the first plate 421 and the second plate 422 after passing through the second holes 410, and the electric field generating unit 43 includes a first electrode plate 421 and a second plate 422 arranged at an angle, and a collecting tank 420 for accommodating debris is formed between the first plate 421 and the second plate 422, and the collecting tank 420 is arranged toward the mesh plate 412 so that the debris can fall into the bottom of the collecting tank 420 along the first plate 421 and the second plate 422 after passing through the second holes 410, and the electric field generating unit 43 includes a first electrode plate 4 31 and a second electrode plate 432, the first electrode plate 431 is arranged on the side of the first plate 421 away from the second plate 422, and the second electrode plate 432 is arranged on the side of the second plate 422 away from the first plate 421. When a voltage is applied between the first electrode plate 431 and the second electrode plate 432, an electric field can be generated between the first electrode plate 431 and the second electrode plate 432. When negatively charged debris enters the collecting tank 420 with the airflow, it can be forced to move toward the electrode plate with the opposite charge by the electrostatic force. When the debris loses electrons on the electrode plate, it will settle along the first plate 421 or the second plate 422 to the bottom of the collecting tank 420, thereby achieving the purpose of collection.

[0040] In some embodiments, the electric adsorption device 40 may further include a second fan (not shown), which is disposed in the installation space 430 to generate negative pressure. Specifically, in this embodiment, part of the second hole 410 may also connect the clothing receiving cavity 441 and the installation space 430 to generate negative pressure in the installation space 430, and the negative pressure may cause the airflow in the clothing receiving cavity 441 to carry debris and flow toward the installation space 430, wherein a part of the debris enters the collection tank 420 and is deposited in the collection tank 420 under the action of the electric field, and another part of the debris enters the space area in the installation space 430 except the collection tank 420, so that as much debris as possible can be collected through the action of the second fan, thereby reducing the debris content attached to the clothes.

[0041] In some embodiments, the electric adsorption device 40 further includes a receiving box 44, which is disposed in the installation space 430 and is used to collect debris entering the installation space 430. Specifically, when the second fan forms a negative pressure in the installation space 430, a portion of the debris enters the collection tank 420 under the action of the negative pressure, and the debris entering the collection tank 420 can be deposited in the collection tank 420 under the action of the electric field, while another portion of the debris directly enters the installation space 430 under the action of the negative pressure, and the debris entering the installation space 430 can be deposited in the receiving box 44, thereby improving the debris accumulation capacity of the electric adsorption device 40.

[0042] The electric adsorption device 40 also includes a frame 45 fixed to the box 10, and the housing 41 (or the positioning seat 80) is fixed above the frame 45 along the gravity direction.

[0043] To facilitate a better understanding of the technical solution of the embodiment of the present application, this specification provides the following schematic description of the working process of the dryer 1 provided in the embodiment of the present application.

[0044] Specifically, when the dryer 1 dries clothes, the barrel 20 rotates to unfold the clothes, and the negative ion generator 30 releases electrons into the clothing holding cavity 441 of the barrel 20. The electrons combine with oxygen molecules in the air to form negative ions. A part of the negative ions fully contact the clothes to play a role in sterilization and disinfection. At the same time, a large amount of debris is raised during the rotation of the barrel 20, and another part of the negative ions attach to the debris to make the debris charged. The debris can be some hair debris, dust, and microorganisms. Under the action of the first fan 60 and the second fan, the debris will flow into the collection tank 420, and the negatively charged debris will be electrically neutralized with the positively charged electrode plate in the collection tank 420 and settle to the bottom of the tank, thereby achieving the purpose of collection.
