The hot drying air flow enters the diversion channel 20a from the first air inlet 30a again, and enters the clothes treatment cavity from the air inlet 40a again, and the circulation operation is carried out, so that the continuous and efficient drying of the clothes is realized.

The specific type of the dehumidifier is not limited, and the dehumidifier can be an evaporator of a heat pump system or a water cooler. Specific types of heaters are not limited, for example, a resistance wire, a PTC (Positive Temperature Coefficient), a condenser of a heat pump system, and the like.

In some embodiments, the door 32 has a light-transmitting region (not shown), and referring to fig. 1 and 4, the electrode 12 of the plasma generator 10 is exposed to the air inlet 40a, so that the glow generated by the electrode 12 can be observed from the front side of the light-transmitting region in the front-back direction.

In some embodiments, referring to fig. 7, the plasma generation device 10 includes a power line 13, a cylindrical protective housing 11, and the electrode 12, wherein the electrode 12 and the power line 13 are accommodated in the cylindrical protective housing 11.

The power supply line 13 supplies high voltage power to the electrode 12, and generates high voltage discharge in the electrode 12 to generate plasma. The columnar protective shell 11 plays a role in protecting the electrode 12 and the power line 13, on one hand, the electrode 12 and the power line 13 are prevented from being in direct contact with external objects, and damage to the electrode 12 and the power line 13 caused by collision and friction is avoided; on the other hand, the user is prevented from directly contacting the charged electrode 12 and the power line 13, improving the safety of the laundry treating apparatus.

A part of the column-shaped protective shell 11 is inserted into the rear cover 20 from the circumferential direction of the rear cover 20, and the plasma generation device 10 is connected to the rear side wall 31 through the column-shaped protective shell 11. The insertion position of the column-shaped protective shell 11 is located at the circumferential direction of the rear cover 20, so that the plasma generating device 10 can be arranged along the surface of the box body 30 without influencing the length dimension of the box body 30 along the front-back direction, the plasma generating device 10 is prevented from protruding out of the rear side surface of the rear cover 20 along the front-back direction, and the adaptability of the clothes treatment equipment is improved.

The specific shape of the columnar protective case 11 is not limited as long as it can be easily inserted into the rear cover 20 without shielding the glow of the electrode 12.

For example, in some implementations, referring to fig. 13, the protective column 11 is substantially straight rod-shaped. The length from the power line outlet (not shown in the figure) of the power line 13 on the rear side wall 31 to the inserting position of the power line inserted into the rear cover 20 is short, so that the material is saved, the electromagnetic interference of the power line 30 to surrounding electric elements is reduced, the overall size of the plasma generating device 10 is correspondingly reduced, the appearance is simple, the manufacturing is convenient, and the production cost is reduced.

For another example, referring to fig. 2 to 9, in other embodiments, the protective casing 11 is substantially in the shape of a bent rod, for example, substantially in an L-shape.

In some embodiments, the column-shaped protective shell 11 is located at the upper end of the rear cover 20, on one hand, the outer circumference of the upper end of the rear cover 20 has a larger installation space, which facilitates the arrangement of the column-shaped protective shell 11, and on the other hand, the column-shaped protective shell 11 is as close to the power line outlet as possible, which reduces the length of the power line 30.

It can be understood that an auxiliary limiting structure may be disposed on the cylindrical protective shell 11 or the rear cover 20 to limit the insertion depth of the cylindrical protective shell 11, so as to position the cylindrical protective shell 11 during the assembly process, thereby improving the assembly efficiency.

It can be understood that the form of the auxiliary limiting structure is not limited, for example, in some embodiments, a threaded hole is provided on the rear cover 20, an external thread is provided on the circumferential outer surface of the cylindrical protective shell 11, the external thread of the cylindrical protective shell 11 is matched with the threaded hole on the rear cover 20, and the insertion depth is controlled by the number of screwing turns.

In other embodiments, referring to fig. 3 and 7, the cylindrical protective shell 11 is provided with a step surface 11a in the circumferential direction, and the outer surface of the rear cover 20 abuts against the step surface 11 a. In the assembling process, the columnar protective shell 11 can be quickly inserted into the rear cover 20 from the outside to the inside until the step surface 11a abuts against the outer surface of the rear cover 20, and at this time, the electrode 12 is at the insertion depth required by the design. Therefore, the plasma generating device 10 can be quickly positioned, and the batch consistency of products is improved; and the step surface 11a has a simple structure, is easy to manufacture and is convenient to operate.

It is understood that in some embodiments, the cylindrical protective shell 11 may be an integrally formed structure, thereby reducing the assembly process of the plasma generation device 10 and improving the structural strength.

In other embodiments, the cylindrical protective shell 11 may also be composed of different parts, so that on one hand, the manufacturing difficulty of the cylindrical protective shell 11 can be reduced, and the production cost can be reduced, and on the other hand, different parts can be respectively matched with the electrode 12 and the power line 13, so as to improve the protection effect on the electrode 12 and the power line 13.

For example, in some embodiments, referring to fig. 7, the column-shaped protective housing 11 includes an electrode protective housing 113, a line protective housing 111, and a sealing member 112, the electrode 12 is disposed in the electrode protective housing 113, and the power line 13 is disposed in the line protective housing 111. The electrode protective case 113, the line protective case 111, and the sealing member 112 are independent components.

The electrode protection shell 113 is used for protecting the electrode 12, the circuit protection shell 111 is used for protecting the power line 13, the functions of the electrode protection shell and the circuit protection shell are separated, when any one of the electrode protection shell and the circuit protection shell is damaged, only the damaged component needs to be replaced independently, the integral replacement is not needed, and the later-period use and maintenance cost is reduced; in addition, the electrode protection shell 113 and the line protection shell 111 can be optimized individually according to the routing condition of the power line 13 and the shape of the electrode 12, so that the protection effect is improved specifically.

The sealing member 112 is connected between the electrode protective case 113 and the line protective case 111 and closes one end of the electrode protective case 113 near the sealing member 112, that is, the motor protective case 113 and the line protective case 111 are connected by the sealing member 112.

The rear housing 20 is provided with mounting holes (not shown) through which the sealing members 112 are sealingly disposed. The sealing element 112 can seal the mounting hole, so as to prevent air flow and plasma in the flow guide channel 20a from escaping from the mounting hole, ensure the air tightness inside the flow guide channel 20a, and improve the sterilization and odor removal efficiency of the clothes treatment equipment.

The electrode protection shell 113 and the line protection shell 111 can be manufactured by injection molding and integral molding, and can also be manufactured by splicing a plurality of plates.

It is understood that, in order to prevent the user from being injured by the leakage problem that may be generated by the power line 13 and the electrode 12, the electrode protection case 113 and the circuit protection case 111 are insulated appropriately, for example, by using a plastic material.

The sealing member 112 may be made of a material having elasticity, such as rubber or silicone. On one hand, the sealing element 112 made of elastic material can deform, so that the sealing element 112 can be conveniently inserted into the mounting hole on the rear cover 20, and on the other hand, after the sealing element 112 is inserted, the elastic material can restore the deformation, so that the space in the mounting hole is occupied, and the sealing performance is improved.

It is understood that the structure of the electrode shield 113 or the line shield 111 can be simplified by using the structure of the rear sidewall 31 or the rear cover 20 itself, thereby reducing material and manufacturing costs and facilitating maintenance.

For example, in some embodiments, referring to fig. 2, 6 and 8, the line protection cover 111 is open to a side of the rear sidewall 31 and attached to the rear sidewall 31. The power line 13 is protected by a protection cavity formed by the circuit protection shell 111 and the rear side wall 31. The structural style of the circuit protection shell 111 can facilitate injection molding manufacturing, and the cost of a mold and raw materials is reduced. In addition, the circuit protection shell 111 can be directly observed through the open position after being detached from the rear side wall 31, so that the maintenance and processing of a user are facilitated, and the user experience is improved. Furthermore, the structure form that one side of the line protection casing 111 is opened reduces the length dimension of the line protection casing 111 along the front-back direction of the clothes treatment apparatus, so as to meet the requirement that the plasma generation device 10 does not exceed the back side of the rear cover 20, and enable the line protection casing 111 to relatively stably abut against the surface of the back side wall 31 of the box body 30.

It is understood that, in order to facilitate the connection of the line protection cover 111 and the rear side plate 31, for example, in some embodiments, a through hole may be provided on the line protection cover 111, and a threaded hole may be provided on the rear side wall 31, and a screw may pass through the through hole and be screwed into the threaded hole to fix the line protection cover 111. For another example, in some embodiments, the circuit protection shell 111 is provided with the elastic buckle 1113, the front end of the elastic buckle 1113 is provided with a barb, the rear sidewall 31 is provided with a buckle mounting hole, and the barb of the elastic buckle 1113 can extend into the buckle mounting hole and abut against the inner wall of the rear sidewall 31, so that the rear sidewall 31 and the circuit protection shell 111 are quickly connected, the assembling time is saved, and the assembling efficiency is improved.

It is understood that, in some embodiments, only the through hole may be disposed on the circuit protection shell 111, and the elastic buckle 1113 is not disposed; in other embodiments, the circuit protection shell 111 may be provided with only the elastic buckle 1113 and no through hole; in still other embodiments, the line protection shell 111 may be provided with the elastic buckle 1113 and the through hole.

Illustratively, in some embodiments, referring to fig. 8, the edge of the open position of the line protection cover 111 is provided with a through hole (not shown) and a plurality of spaced elastic buckles 1113. When the circuit protection shell 111 is installed, the plurality of elastic buckles 1113 are firstly clamped into buckle installation holes (not shown in the figure) on the rear side wall 31, so that the elastic buckles 1113 are abutted to the inner surface of the rear side wall 31, and then the elastic buckles are connected with threads (not shown in the figure) arranged on the rear side wall 31 by screws penetrating through the through holes, so that the installation and the positioning of the circuit protection shell 111 are realized. The joint of elasticity buckle 1113 is convenient rapidly, can reduce the equipment time.

In some embodiments, referring to fig. 8 and 10, a plurality of limiting ribs 1111 are disposed inside the circuit protection casing 111, the limiting ribs 1111 are arranged at intervals along an extending direction of the circuit protection casing 111, a top side of one of two adjacent limiting ribs 1111 contacts the power line 13, and a bottom side of the other limiting rib 1111 contacts the power line 13. The matching mode of each limiting rib 1111 and the power line 13 is beneficial to the standardized arrangement of the routing of the power line 13 in the production process, and the power line 13 is prevented from being orderly and disorderly accumulated and extruded in the circuit protection shell 111, so that the subsequent overhaul and maintenance are facilitated; the power line 13 is arranged in a zigzag manner in the circuit protection shell 111, so that the power line 13 is subjected to two acting forces in opposite height directions, the power line 13 is prevented from arching or sinking in only one direction, and the limiting rib 1111 plays a role in positioning the power line 13; because two adjacent limiting ribs 1111 are in limiting contact with the power line 13 from the top side and the bottom side respectively, the power line 13 is located in the middle of the line protection shell 111 in the height direction, and the friction probability between the power line 13 and the line protection shell 111 is further reduced.

Illustratively, the limiting ribs 1111 are provided with limiting grooves 1111a, and the power supply line 13 abuts against the limiting grooves 1111a, that is, the limiting grooves 1111a of one of the limiting ribs 1111 are on the top side and the limiting grooves 1111a of the other limiting rib 1111 are on the bottom side, of two adjacent limiting ribs 1111.

Power cord 13 can the joint in spacing recess 1111a, prevents that power cord 13 from sliding on spacing muscle 1111, has reduced the friction between power cord 13 and spacing muscle 1111 when the position of fixed power cord 13.

In some embodiments, referring to fig. 9, a process hole 1111b is formed in the circuit protection shell 111, and the process hole 1111b penetrates through the circuit protection shell 111 and is located behind the limiting rib 1111. The fabrication holes 1111b facilitate demolding during injection molding manufacturing of the limiting ribs 1111, and production efficiency is improved.

In some embodiments, referring to fig. 7, 8 and 11, one end of the line protection casing 111 close to the sealing member 112 is provided with a rib 1112 extending inwards, an outer surface of the sealing member 112 for contacting and matching with the line protection casing 111 is provided with a mounting groove 112a, and the sealing member 112 can be snapped into the line protection casing 111 from an opening of the line protection casing 111, so that the rib 1112 is snapped into the mounting groove 112 a. The rib 1112 is clamped with the mounting groove 112a, so that while the connection between the sealing element 112 and the line protection shell 111 is ensured to be firm, in the process that the plasma generation device 10 is plugged in and pulled out of the mounting hole, the clamping direction between the mounting groove 112a and the rib 1112 is different from the plugging direction of the plasma generation device 10, and therefore, the probability that the sealing element 112 and the line protection shell 111 are separated from each other in plugging of the plasma generation device 10 can be reduced.

It should be noted that the engagement direction between the mounting groove 112a and the rib 1112 and the inserting and extracting direction of the plasma generating apparatus 10 may be any suitable angle as long as the two are not parallel.

For example, referring to fig. 7, the inserting and extracting direction of the plasma generating device 10 is perpendicular to the inserting and extracting direction between the sealing member 112 and the line protecting shell 111, so that the acting force of the mutual abutting between the rib 1112 and the mounting groove 112a is improved, and the connection stability between the rib 1112 and the mounting groove 112a during the inserting and extracting process of the plasma generating device 10 is further improved.

In order to increase the diffusion speed of the plasma, in some embodiments, the electrode protection housing 113 may be provided with a plurality of through meshes (not shown), and the gas flow may enter the electrode protection housing 113 through the meshes (not shown) and contact the electrode 12, so as to bring the plasma into the cylinder 40, thereby accelerating the diffusion of the plasma.

It will be appreciated that the mesh may be open on the windward side of the electrode protective casing 113 to facilitate airflow.

During the drying process of clothes, the air flow of the fluff is carried to flow in the circulating channel, and the fluff is easily generated. In some embodiments, at least a portion of the electrode protection shell 113 can block the air flow blown into the flow guide channel 20a on the electrode 12, so as to prevent the lint from being wound on the electrode 12, prevent the lint from affecting the discharge of the electrode 12, and ensure the efficiency of plasma generation; on the other hand, the current generated by the electrode 12 is prevented from melting or burning the flocs, so that the service life of the electrode 12 is prevented from being reduced due to melting or burning of the flocs, and the potential safety hazard caused by damage to the electrode 12 is prevented.

On the premise of not affecting the observation of the glow generated by the electrode 12 by the user, the electrode protection shell 113 may shield all the surfaces of the electrode 12 blown by the airflow in the flow-guiding channel 20a, or may shield only the surface of the electrode 12 directly blown by the airflow in the flow-guiding channel 20 a.

For example, in some embodiments, referring to fig. 12, the electrode protection case 113 is provided with a receiving cavity 113a for receiving the electrode 12, the receiving cavity 113a is opened toward one side of the intake vent 40a, and the plasma generated by the electrode 12 is discharged only through the opened portion of the receiving cavity 113 a. On one hand, the electrode protection shell 113 can shield the windward side of the electrode 12, and prevent the lint from attaching to the electrode 12 along the airflow in the flow guide channel 20 a; on the other hand, the glow generated by the discharge of the electrode 12 can only be emitted from the opening, which is convenient for the user to observe.

The specific structural shape of the electrode protection shell 113 is not limited, for example, in some embodiments, referring to fig. 12, the electrode protection shell 113 includes an electrode protection shell back plate 1133, an electrode protection shell bottom plate 1134, and two electrode protection shell side plates 1132, the electrode protection shell back plate 1133, the electrode protection shell bottom plate 1134, and the electrode protection shell side plates 1132 together enclose to form an accommodation cavity 113a, the electrode protection shell back plate 1133 is located behind the electrode 12, the two electrode protection shell side plates 1132 are disposed on the front side of the protection shell back plate 1133 and located at the left and right opposite ends of the protection shell back plate 1133, and the electrode protection shell bottom plate 1134 is located at one end of the electrode 12 away from the sealing member 112. The electrode protection shell back plate 1133, the electrode protection shell bottom plate 1134 and the electrode protection shell side plate 1132 isolate the windward side of the electrode 12 from the flow guide channel 20a, so that impurities such as lint are prevented from directly blowing to the electrode 12.

It will be appreciated that since the electrodes 12 require electrical discharge, the electrode shield backing 1133, electrode shield bottom panel 1134, and electrode shield side panel 1132 should be spaced a distance from the electrodes 12 to avoid direct contact with the electrodes 12.

In some embodiments, referring to fig. 12, an insertion boss 1131 protruding from a circumferential surface of the electrode protection shell 113 is disposed at an end of the electrode protection shell 113 close to the sealing element 112, the sealing element 112 is provided with a mounting cavity (not shown), a corresponding sidewall of the mounting cavity is provided with an insertion ring groove (not shown), one end of the electrode protection shell 113 is inserted into the mounting cavity, and the insertion boss 1131 is snapped into the insertion ring groove.

In the process that the electrode protection shell 113 is inserted into the mounting cavity of the sealing element 112, the electrode protection shell 113 forces the sealing element 112 to generate elastic deformation, so that the electrode protection shell 113 is conveniently and smoothly inserted into the mounting cavity. The insertion boss 1131 abuts against the insertion ring groove, and the insertion ring groove applies an acting force opposite to the pulling-out direction to the insertion boss 1131, so that the probability that the electrode protection shell 113 is pulled out is reduced.

The specific structure of the rear cover 20 is not limited as long as it can guide the air flow from the first tuyere 30a to the second tuyere 30 b.

Illustratively, 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 disposed around an edge of the flat bottom portion 22 and protrudes from a side of the flat bottom portion 22 facing the box body 30, the side wall portion 21 and the flat bottom portion 22 enclose to form a flow guide channel 20a, the side wall portion 21 is sealingly attached to an outer surface of the rear side wall 31, and the plasma generation device 10 is disposed on the side wall portion 21. The flat bottom 22 is provided in a flat plate shape for easy processing. The use of the rear sidewall 31 to close the open side of the rear housing 20 reduces the structural weight of the rear housing 20, facilitates assembly, and also saves material. The plasma generating device 10 is located on the side wall portion 21, so that the plasma generating device 10 does not protrude from the rear surface of the flat bottom portion 22 in the front-rear direction, and the length of the clothes treating apparatus in the front-rear direction is prevented from being increased.

Note that, in the present embodiment, the rear side surface of the rear cover 20 is the rear surface of the flat bottom 22.

In some embodiments, referring to fig. 5, the rear sidewall 31 includes a back plate 312 and a balance frame 311, the back plate 312 is provided with an avoiding through hole (not shown) corresponding to the rear end of the barrel 40, and the balance frame 311 is provided in the avoiding through hole. The balance frame 311 is disposed at a middle position in the bearing hole 311a, and a rotating shaft (not shown) is provided in the laundry treating apparatus, the rotating shaft being rotatably inserted in the bearing hole 311a, and the drum 40 is rotatably supported on the balance frame 311 by the rotating shaft. The hollow region of the balance frame 311 forms the second tuyere 30 b.

The electrode 12 of the plasma generator 10 is not shielded by the balance frame 311.

For example, in some embodiments, referring to fig. 2 and 14, the plasma generating apparatus 10 may be configured in a bent shape, such as an L shape, a straight rod shape, or other suitable shape, so that the electrode 12 avoids the projection range of the balancing frame 311 in the front-back direction, thereby facilitating the user to observe the glow.
