The electrode 12 of the plasma generator 10 is located in the guide channel 20a, and the strong oxidizing substances generated after ionization can quickly enter the cylinder along the drying airflow in the guide channel 20a and diffuse, thereby improving the efficiency of sterilization and deodorization.

In addition, the plasma generator 10 is installed by snapping into the installation groove from the edge of the rear cover 20, and only needs to add an installation groove on the basis of the existing rear cover 20, and can be installed on the existing rear cover 20, the existing mold can be upgraded to the mold of the rear cover 20 of the embodiment of the present application, which can greatly reduce the production cost.

In some embodiments, referring to FIG. 6, the rear cover 20 includes a side wall portion 21 and a flat bottom portion 22. The side wall portion 21 is arranged around the edge of the flat bottom portion 22 and protrudes from the side of the flat bottom portion 22 facing the box body 30. The side wall portion The part 21 and the flat bottom part 22 are surrounded to form the guide channel 20a, and the side part 21 is attached to the rear surface of the rear panel 31 in a sealing manner. The flat bottom 22 is set in a flat plate shape, which is convenient for processing. Utilizing the back panel 31 to close the open side of the rear cover 20 can reduce the structural weight of the rear cover 20 , facilitate assembly, and save materials.

It can be understood that the installation position of the plasma generating device 10 on the rear cover 20 is conducive to reducing the overall geometric size of the laundry treatment equipment, and facilitates the placement of the laundry treatment equipment.

Specifically, referring to Fig. 6 and Fig. 7, the installation groove is provided on the side wall portion 21, and the installation groove is open toward the rear panel 31, and the position where the plasma generator 10 is embedded in the installation groove is interposed between the rear cover 20 and the rear panel.

In addition, the plasma generator 10 is arranged between the back cover 20 and the back plate 31, and the bonding between the back cover 20 and the plasma generator 10 and the back plate 31 and the plasma generator 10 are used to improve conduction. The airtightness of the flow channel 20a reduces the probability of the airflow overflowing during the working process of the clothes processing equipment, thereby promoting the disinfection effect and improving the user experience.

It can be understood that the cooperation between the structure of the installation groove and the structure of the part where the plasma generator 10 is embedded in the installation groove facilitates the insertion and positioning of the plasma generator 10 in the installation groove.

Specifically, referring to Fig. 7, the width of the installation groove gradually narrows along the embedding direction, and the position where the plasma generating device 10 is embedded in the installation groove gradually narrows along the embedding direction, and the position where the plasma generating device 10 is embedded in the installation groove is in line with the groove of the installation groove. wall abutment. It is convenient to align the plasma generator 10 with the card entrance during installation. The width of the installation groove is gradually narrowed, so that the groove wall of the installation groove acts as a guide, so that the plasma generator 10 can be installed to a predetermined position along the insertion direction. Through the abutment of the plasma generator 10 and the tank wall, on the one hand, the friction force between the two can be used to limit the position of the plasma generator 10; The airflow and the possibility of leakage of strong oxidizing substances generated by the plasma generator 10 improve the efficiency of disinfection and sterilization.

It can be understood that an auxiliary structure may be provided on the groove wall of the installation groove and the position where the plasma generator 10 is embedded in the installation groove to improve sealing and friction. The groove wall of installation groove and/or the position that plasma generation device 10 is embedded in the installation groove is made of elastic soft material, such as rubber, silica gel etc., after plasma generation device 10 is embedded in installation groove, the groove wall of installation groove and plasma generation device At least one of the parts 10 embedded in the installation groove is deformed, and the extrusion force generated by the deformation improves the friction and sealing performance between the two, reduces the possibility of slippage of the plasma generating device 10, and improves the Disinfection and sterilization efficiency.

In some embodiments, referring to FIG. 8 , the plasma generator 10 includes a power cord 13, a columnar protective case 11 and the above-mentioned electrodes 12, the electrodes 12 and the power cord 13 are housed in the cylindrical protective case 11, and the power cord 13 is electrically connected to the electrode 12. connect.

The power line 13 supplies high-voltage electricity to the electrode 12, so that the electrode 12 generates a high-voltage discharge to generate plasma. The columnar protective shell 11 protects the electrode 12 and the power line 13. On the one hand, it prevents the electrode 12 and the power line 13 from directly contacting with external objects, and avoids damage to the electrode 12 and the power line 13 due to collision and friction; on the other hand, The user is prevented from directly contacting the charged electrode 12 and the power cord 13, and the safety of the clothes processing equipment is improved.

It can be understood that the columnar protective shell 11 is embedded in the installation groove to avoid direct contact between the electrode 12 and the rear cover 20, and reduce the risk of electric shock to the user caused by the electrode 12 conducting current to the rear cover 20. At the same time, the columnar protective shell 11 Compared with the electrode 12, it can have higher structural strength, so when embedded in the installation groove, it can bear the pressing force exerted by the groove wall of the higher installation groove, thereby improving the stability of the installation of the plasma generating device 10 and the sealing of the embedded position.

In some implementations, the cylindrical protective shell 11 is in the shape of a straight rod. The length of the power cord 13 from the power cord outlet on the back panel 31 to the insertion position of the rear cover 20 is relatively short, which saves materials and reduces the electromagnetic interference of the power cord 13 to the surrounding electrical components. The overall size of the plasma generating device 10 is reduced, the appearance is simple and easy to manufacture, and the production cost is reduced.

In some embodiments, the columnar protective shell 11 is roughly in the shape of a bent rod, such as roughly L-shaped.

In some embodiments, the columnar protective shell 11 is located at the upper end of the back cover 20. On the one hand, there is a larger installation space around the upper end of the rear cover 20, which is convenient for arranging the columnar protective shell 11. On the other hand, the columnar protective shell 11 As close as possible to the outlet of the power cord 13 to reduce the length of the power cord 13.

It can be understood that, in some embodiments, the columnar protective shell 11 can be an integrally formed structure, so as to reduce the assembly process of the plasma generator 10 and improve the structural strength.

In some other embodiments, the columnar protective shell 11 can also be composed of different parts. On the one hand, it can reduce the manufacturing difficulty of the columnar protective shell 11 and reduce the production cost. On the other hand, different parts can be separated from the electrode 12 and the power line 13 Adapting to improve the protection effect of the electrode 12 and the power line 13.

Specifically, referring to FIG. 8 , the columnar protective shell 11 includes an electrode protective shell 113 , a line protective shell 111 and a seal 112 , the electrode 12 is disposed in the electrode protective shell 113 , and the power cord 13 is disposed in the line protective shell 111 . It should be noted that the electrode protection case 113 , the line protection case 111 and the sealing member 112 are independent parts.

The electrode protection shell 113 is used to protect the electrode 12, and the circuit protection shell 111 is used to protect the power line 13. The functions of the two are separated. When any one of the two is damaged, the damaged component only needs to be replaced separately, and there is no need to replace the whole, which reduces the later stage. Use and maintenance costs; in addition, the electrode protection shell 113 and the circuit protection shell 111 can be individually optimized according to the routing of the power line 13 and the shape of the electrode 12, so as to improve the protection effect in a targeted manner.

The electrode protection shell 113 and the circuit protection shell 111 can be manufactured by injection molding, or can be made by splicing multiple plates.

It can be understood that, in order to prevent the possible leakage of the power line 13 and the electrode 12 from causing harm to the user, the electrode protection shell 113 and the line protection shell 111 are properly insulated, such as made of plastic.

The seal 112 is connected between the electrode protection case 113 and the line protection case 111 , and closes an end of the electrode protection case 113 close to the seal 112 . That is, the electrode protection case 113 and the line protection case 111 are connected through the sealing member 112 . The electrode protection shell 113 is separated from the line protection shell 111 by the seal 112 and the sealing connection between the seal 112 and the electrode protection shell 113 reduces the probability that the strong oxidizing substance generated after ionization enters the protection shell from the electrode protection shell 113 , reduce the overflow of strong oxidizing substances, and improve the sterilization and disinfection effect.

In some embodiments, the rear cover 20 is fixed on the rear panel 31 , and the seal 112 is sandwiched between the rear cover 20 and the rear panel 31 .

The sealing member 112 is attached to the rear panel 31 and the sealing member 112 is attached to the rear cover 20 , so that the sealing member 112 is sealed and embedded in the installation groove. The sealing member 112 separates the diversion channel 20a from the outside world, reduces the probability of strong oxidizing substances generated after ionization overflowing from the diversion channel 20a, and improves the sterilization and disinfection effect.

It can be understood that the sealing member 112 is made of elastic material. On the one hand, the sealing member 112 is deformed in the process of being embedded in the installation groove, so that the plasma generator 10 can be installed; on the other hand, the sealing member 112 is embedded in the installation groove Deformation occurs to improve friction and sealing between the two, reducing the possibility of slippage of the plasma generator 10 and reducing the overflow of strong oxidizing substances. The sealing member 112 can be made of materials such as rubber and silica gel.

It can be understood that an auxiliary limit structure can be set on the plasma generating device 10 or the rear cover 20 or the rear back plate 31 to limit the dimension depth of the plasma generating device 10 in the rear cover 20, so as to facilitate the control of the plasma during the assembly process. The generating device 10 is positioned to improve assembly efficiency.

It can be understood that the specific form of the auxiliary limiting structure is not limited.

For example, referring to FIG. 4 , one of the sealing member 112 and the back plate 31 is provided with a positioning protrusion 1121 , and the other is provided with a positioning hole, and the positioning protrusion 1121 is inserted into the positioning hole. Through the abutment between the positioning protrusion 1121 and the wall of the positioning hole, the installation position of the plasma generating device 10 is limited, and the risk of displacement of the plasma generating device 10 due to vibration and other reasons during the working process of the laundry processing equipment is reduced. .

It can be understood that the positioning protrusion 1121 is provided with a barb, so that the positioning protrusion 1121 can hook the inner wall of the positioning hole after being inserted into the positioning hole, so as to improve the stability of the installation of the plasma generator 10 .

It can be understood that the positioning protrusion 1121 is made of elastic material, and the positioning protrusion 1121 is deformed during the process of being inserted into the positioning hole, so that the positioning protrusion 1121 can smoothly enter the positioning hole.

It can be understood that the structure of the back plate 31 or the rear cover 20 itself can be used to simplify the structure of the electrode protection case 113 or the circuit protection case 111 , thereby reducing material and manufacturing costs and facilitating maintenance.

Specifically, referring to FIG. 4 and FIG. 8 , the circuit protection case 111 is opened on one side facing the backplane 31 and attached to the backplane 31 . A protection cavity is formed by the line protection shell 111 and the back panel 31 to protect the power line 13 inside. The structural form of the circuit protection case 111 can be easily manufactured by injection molding, which reduces the cost of molds and raw materials. In addition, after the circuit protection case 111 is removed from the rear panel 31 , the condition of the internal power line 13 can be directly observed through the opening, which is convenient for users to maintain and handle, and improves user experience. Furthermore, the open structure of one side of the line protection case 111 reduces the length dimension of the line protection case 111 along the front and back direction of the laundry treatment equipment, which facilitates the realization of the requirement that the plasma generating device 10 does not exceed the rear side of the rear cover 20, It can also make the circuit protection case 111 relatively stable against the surface of the rear panel 31 of the box body 30 .

It can be understood that, in order to facilitate the connection between the circuit protection case 111 and the back panel 31, for example, a through hole may be provided on the circuit protection case 111, and a threaded hole may be provided on the back panel 31, and a screw passes through the through hole and is screwed into the threaded hole. In the hole, the line protection shell 111 is fixed. For another example, an elastic buckle is arranged on the line protection shell 111, a barb is arranged at the front end of the elastic buckle, and a buckle installation hole is arranged on the back panel 31, and the barb of the elastic buckle can be inserted into the buckle installation hole and abut against the inner wall of the rear panel 31 , thereby realizing quick connection between the rear panel 31 and the circuit protection case 111 , saving assembly time and improving assembly efficiency.

It can be understood that the specific structures of the sealing member 112 , the electrode protection case 113 and the circuit protection case 111 are optimized so that the sealing member 112 can be assembled with them.

For example, referring to FIG. 8 , the sealing member 112 snaps into the line protection shell 111 from the open position of the line protection shell 111 and abuts against the inner wall of the line protection shell 111 . The connection between the sealing member 112 and the circuit protection shell 111 is realized through the friction force and extrusion force. The direction in which the sealing member 112 snaps into the circuit protection shell 111 is the same as the direction in which the sealing member 112 is inserted into the installation groove. In order to facilitate the separate disassembly and assembly of the line protection case 111 or the rear cover 20, and improve the follow-up maintenance efficiency, for example, when maintaining the power cord 13 inside the line protection case 111, the line protection case 111 needs to be removed separately, and the line protection case 111 is relatively sealed. When 112 is separated outward, the sealing member 112 is applied with the same force as the direction in which the sealing member 112 is embedded in the installation groove, so that the sealing member 112 can be more firmly located in the installation groove, and the process of separating the line protection shell 111 is reduced. The probability of the sealing member 112 being loosened or coming out along with the circuit protection case 111 improves the efficiency of disassembly and assembly.

It can be understood that positioning structures are provided on the electrode protection shell 113 and/or the line protection shell 111 to facilitate the positioning of the sealing member 112 and the two.

The specific form of the positioning structure is not limited.

For example, one end of the circuit protection case 111 near the sealing member 112 is provided with an inwardly extending rib, and the outer surface of the sealing member 112 used to contact and cooperate with the circuit protection case 111 is provided with a mounting groove, and the sealing member 112 can be protected from the circuit. The opening of the shell 111 is snapped into the circuit protection shell 111 so that the ribs snap into the installation groove. Through the cooperation of the ribs and the installation grooves, the installation position of the sealing member 112 is limited, and the probability of separation between the sealing member 112 and the circuit protection case 111 during the working process of the laundry treatment device is reduced.

For another example, referring to FIG. 9 , there are two limit posts 1111 inside the circuit protection case 111, and the two limit posts 1111 are arranged at intervals along the extending direction of the circuit protection case 111. Between the limit posts 1111. The installation position of the sealing member 112 is limited by the two limit posts 1111, which reduces the displacement of the sealing member 112 along the extension direction of the line protection shell 111 due to vibration and other reasons during the working process of the laundry processing equipment, thereby causing the occurrence of a gap between the two. probability of leaving.

It can be understood that when the electrode 12 is working, it can generate glow due to discharge, and the user can judge whether the electrode 12 is working normally by observing the glow. Therefore, the arrangement of the various components in the laundry processing device should enable the user to observe the glow and at the same time realize corresponding functions.

For example, under the premise of not affecting the user's observation of the glow produced by the electrode 12, the electrode protective shell 113 can block all the surfaces on the electrode 12 that are blown by the airflow in the flow guide channel 20a, or focus only on the electrode 12. The surface directly blown by the airflow in the guide channel 20a is shielded. In order to reduce the risk of the lint generated during the drying process of the clothes being entangled on the electrode 12, avoid the shortening of the service life of the electrode 12 due to the melting or burning of the lint, and reduce the potential safety hazard during use.

Specifically, referring to Fig. 9 and Fig. 10, the electrode protection case 113 is provided with an accommodating chamber 113a for accommodating the electrode 12, the accommodating chamber 113a is open towards the side of the air inlet, and the plasma generated by the electrode 12 is only discharged through the opening of the accommodating chamber 113a . On the one hand, the electrode protective shell 113 can shield the windward side of the electrode 12, preventing fluff from adhering to the electrode 12 along the airflow in the flow guiding channel 20a; Open injection, easy for users to observe.

It can be understood that a positioning groove for the electrode 12 is provided on the inner wall of the accommodating chamber 113a at the end of the electrode protection shell 113 away from the sealing member 112, so that the electrode 12 can be positioned during installation.

It can be understood that the seal 112 is provided with several holes for the power cord 13 passing through the seal 112 , so that the power cord 13 in the circuit protection case 111 is electrically connected to the electrode 12 through the power cord 13 through holes.

In some embodiments, the plasma generating device 10 does not exceed the rear side of the rear cover 20 along the front-to-back direction of the laundry treatment device, preventing the plasma generator 10 from protruding from the rear of the clothes treatment device along the front-to-back direction. This results in an increase in the length of the whole machine along the front and back directions; on the other hand, the rear cover 20 can protect the plasma generator 10 to a certain extent, reducing the probability of collision between external objects and the plasma generator 10 .

In some embodiments, the clothes treatment equipment includes a door body 32 arranged on the front panel, the door body 32 has a light-transmitting area, and the electrode 12 of the plasma generating device 10 is exposed at the air inlet, so that the glow generated by the electrode 12 can be emitted from the air. The front side of the light-transmissive area is observed. When the clothes treatment equipment is working, the user can observe the working condition of the plasma generator 10 at any time, and intuitively observe whether the clothes treatment equipment has the sterilization and disinfection function through the glow of the electrode 12, which has a better visualization effect and improves the user experience. experience.
