The embodiment of the invention provides a clothes treatment device, and the specific type of the clothes treatment device is not limited, and the clothes treatment device can be a washing machine, a clothes dryer and a washing and drying integrated machine. The present embodiment is described taking a washing machine as an example.

Referring to fig. 1, the laundry treating apparatus includes a drum assembly 60 and an electrolysis device 2. Wherein, the clothes treatment equipment is provided with a water inlet passage communicated with the cylinder assembly 60, namely, the water inlet passage can supply water for the cylinder assembly 60, but the water in the cylinder assembly 60 can not enter the water inlet passage. Illustratively, the cartridge assembly 60 includes an outer cartridge 61 and an inner cartridge 62, the inner cartridge 62 being rotatably disposed within the outer cartridge 61.

The inner cylinder 62 can be a perforated inner cylinder or a non-perforated inner cylinder. When the inner cylinder 62 is a perforated inner cylinder, the outer cylinder 61 is used for holding water; when the inner drum 62 is a non-hole inner drum, the inner drum 62 is used for holding water, that is, the inner drum 62 can hold water and clothes, and the water in the inner drum 62 cannot enter the outer drum 61 during the washing process.

Referring to fig. 2, an electrolysis device 2 is disposed on the water inlet passage to electrolyze water in the water inlet passage.

Water used for washing clothes in the clothes treatment equipment is electrolyzed by the electrolysis device 2 to generate hydroxyl free radicals OH with strong oxidation activity, OH has extremely high oxidation potential of 2.80eV and extremely strong oxidation capacity, can generate rapid chain reaction with most organic pollutants, OH can be sterilized and disinfected at low temperature, and does not damage clothes, and a part of OH can react with chlorine molecules in tap water to generate active chlorine which can exist for a long time and has the effect of long-term bacteriostasis; a large amount of hydroxyl free radicals oxidize and destroy chromophoric groups of dye molecules dissociating into water in the colored clothes in the washing process to decolor the dye, prevent the dissociative dye from being stained into light-colored clothes to cause color cross, and continuously react to decompose the dye molecules into harmless carbon dioxide, water and inorganic salt. Meanwhile, the electrolysis device can generate a large amount of micro bubbles, the diameter of the micro bubbles is very small and is usually smaller than 50um, so that the micro bubbles can well enter the inside of the clothes fiber in the washing process, and through the actions of micro bubble blasting and adsorption floating, the micro bubbles are continuously generated to be circularly flushed, so that the detergent is assisted to thoroughly remove sebum, grease, tiny dust and other dirt accumulated in the clothes fiber, and the cleaning effect can be improved.

In the clothes treatment equipment of the embodiment, the water inlet passage is provided with the electrolysis device, so that the electrolysis device 22 can be normally used without using an additional water pump and no matter whether water exists in the outer barrel 61 or the inner barrel 62, and the water entering the outer barrel 61 or the inner barrel 62 can be electrolyzed; furthermore, the water in the water inlet passage is tap water, and the tap water does not contain catkins, so that the electrolytic device cannot be blocked, and the service life of the electrolytic device can be greatly prolonged.

It should be noted that, in the clothes treatment apparatus, the life of the electrolysis device needs to match the design service life of the clothes treatment apparatus, and if the service life of the electrolysis device is substantially less than the design service life of the clothes treatment apparatus, the clothes treatment apparatus may be scrapped in advance, and the consumer benefit may be damaged. The electrolysis device in the embodiment of the invention can not be blocked, and the service life of the electrolysis device can reach the design service life of the clothes treatment equipment.

In one embodiment, the electrolysis device 2 includes the mesh electrode 22, the surface charge density at the mesh of the mesh electrode 22 is larger, and the electric field intensity near the mesh electrode is stronger, so that the electrolysis efficiency can be greatly improved, more active substances such as hydroxyl radicals and active chlorine can be generated, more micro bubbles can be generated, and the sterilization, cross color prevention and washing effects can be improved; the water flow can flow through the grids of the mesh electrode 22, and micro-bubbles on the surface of the mesh electrode 22 can be taken away in time, so that the micro-bubbles are prevented from being gathered to form large bubbles.

In one embodiment, referring to fig. 2, the mesh spacing d of the mesh electrode 22 is 1mm to 10 mm. The grid spacing facilitates, on the one hand, the formation of microbubbles at the grid and, on the other hand, the detachment of microbubbles from the surface of the mesh electrode 22. Specifically, if the mesh pitch is too large, the number of meshes will be small and the number of microbubbles will be small without changing the area and shape of the mesh electrode 22; if the grid interval is too small, the tip area of the grid edge is small, which is not beneficial to generating micro-bubbles, moreover, the generated micro-bubbles are difficult to overflow quickly in the grid, and large bubbles are easily gathered in the grid.

The mesh structure of the mesh electrode 22 may be formed in a variety of suitable ways. Exemplarily, in an embodiment, the grid structure is woven by conductive wire bodies, wherein the diameter of the conductive wire bodies is 0.2mm to 2 mm. The conductive wire body in the diameter range can enable the grid structure to have better structural strength. In another embodiment, the grid structure is formed by a metal plate through a cutting process, so that the grid structure and the frame are of an integral structure, and the reliability of the mesh electrode is improved.

In one embodiment, referring to fig. 10, the electrolysis device 2 further includes a housing 21 and a conductive connector 24 electrically connected to the mesh electrode 22; referring to fig. 12, the housing 21 has an electrolysis chamber 21a, an electrolysis water inlet 21c and an electrolysis water outlet 21d, the mesh electrode 22 is disposed in the electrolysis chamber 21a, an end of the conductive connector 24 close to the mesh electrode 22 is disposed in the housing 21, an end of the conductive connector 24 away from the mesh electrode 22 is disposed outside the housing 21, and the electrolysis chamber 21a is disposed on the water inlet path, that is, water in the water inlet path flows through the electrolysis chamber 21 a.

When the electrolysis device 2 is assembled, the corresponding pipelines can be respectively connected to the electrolysis water inlet 21c and the electrolysis water outlet 21d, and the electrolysis device 2 only needs to be installed in a proper space without carrying out excessive structural change on the clothes treatment equipment.

In one embodiment, referring to fig. 7, the laundry treating apparatus includes a water inlet valve 3 and a detergent box 5, and the detergent box 5 has a storage tank 5a for storing detergent. The type of the detergent contained in the storage tank 5a is not limited, and may be, for example, granular materials such as washing machine powder, and viscous materials such as laundry detergent, and is not limited herein. The electrolysis water inlet 21c is communicated with the water inlet valve 3, the electrolysis water outlet 21d is communicated with the storage tank 5a to guide the electrolysis water in the electrolysis chamber 21a to the storage tank 5a, and the electrolysis water outlet 21d is communicated with the storage tank 5a through a second pipeline 42.

When the clothes treatment equipment works, tap water enters the electrolytic cavity 21a from the electrolytic water inlet 21c, the electrolytic water electrolyzed by the mesh electrode 22 has a plurality of micro bubbles, hydroxyl radicals, active chlorine and the like, the electrolytic water enters the storage tank 5a and dilutes the detergent stored in the storage tank 5a, the micro bubbles can accelerate the dissolution of the detergent, and the detergent enters the outer barrel 61 or the inner barrel 62 along with the electrolytic water after being dissolved.

In one embodiment, with continued reference to fig. 7, the inlet valve 3 has a water inlet 3a, a first water outlet 3b and a second water outlet, wherein the first water outlet 3b is communicated with the electrolysis water inlet 21c, illustratively, through a first pipeline 41; the second outlet is communicated with a storage tank 5a, and the water inlet valve 3 can selectively communicate the water inlet 3a with the first outlet 3b or the second outlet.

When the sterilization and disinfection by the electrolyzed water are required, the water inlet 3a is communicated with the first water outlet 3b, the tap water enters the electrolysis cavity 21a through the water inlet valve 3, the electrolyzed water electrolyzed by the mesh electrode 22 enters the storage tank 5a, and finally enters the outer barrel 61 or the inner barrel 62. When sterilization and disinfection are not needed, the water inlet 3a is communicated with the second water outlet, tap water directly enters the storage tank 5a through the water inlet valve 3 and finally enters the outer cylinder or the inner cylinder 62, namely, the tap water directly enters the storage tank 5a from the water inlet valve 3 without passing through the electrolytic cavity 21a under the condition that sterilization and disinfection are not needed, so that the water inlet speed under the condition that sterilization and disinfection are not needed can be increased, and the washing time is shortened.

In one embodiment, referring to fig. 8, the electrolysis water outlet 21d is located at an end of the casing 21 close to the detergent box 5, and the electrolysis water inlet 21c is located at an end of the casing 21 far from the electrolysis water outlet 21 d. Under the condition that the position of the electrolysis device 2 is unchanged, the distance between the electrolysis water outlet 21d and the electrolysis cavity 21a is shorter than the distance between the electrolysis water inlet 21c and the electrolysis cavity 21a, so that the electrolyzed water in the electrolysis cavity 21a can enter the storage tank 5a in a shorter distance, and the micro-bubbles in the electrolyzed water can more effectively accelerate the dissolution of the detergent.

The position of the electrolysis device 2 in the laundry treatment apparatus is not limited as long as water used for washing laundry in the laundry treatment apparatus can be electrolyzed.

In one embodiment, referring to fig. 6 and 7, the laundry treating apparatus includes a table 1, the table 1 is a main frame of a top portion of the laundry treating apparatus, the table 1 is formed with a laundry input port 1a, the laundry input port 1a faces upward, and laundry is input into the drum 62 through the laundry input port 1 a.

In one embodiment, referring to fig. 5 and 6, the detergent box 5 is fixedly connected to the bottom side of the worktable 1. The detergent box 5 may be provided at any side of the table 1 along the laundry input port 1a, for example, at any side of the table 1 along the rear side, the front side, or the lateral direction of the laundry input port 1 a.

In the embodiment of the present invention, referring to fig. 5, the detergent box 5 is disposed at the rear side of the workbench 1 along the laundry input port 1 a. Generally, the water inlet pipe is arranged at the rear side of the clothes treatment device, therefore, in the embodiment of the invention, the detergent box 5 is arranged at the rear side of the workbench 1 along the clothes input opening 1a, the length of the water inlet pipe communicated with the detergent box 5 can be reduced, the pipe distribution is convenient, and the structure of the workbench 1 can be compact. Further, the rear side and the front side of the table 1 generally have a large space, and the front side of the table 1 may facilitate the arrangement of the operation panel so that the operation panel is closer to the user, so that the user can use the operation panel more conveniently, and thus, the detergent box 5 may be arranged at the rear side of the table 1 along the laundry input port 1 a.

Referring to fig. 7, the table 1 has a detergent input port 1b penetrating the table 1 in a height direction of the laundry treating apparatus, and the detergent box 5 is hermetically disposed around the detergent input port 1 b. When the detergent needs to be put in, the detergent can be directly put in the detergent box 5 from the detergent putting port 1 b. It is understood that, in some embodiments, a shielding cover may be further provided at the detergent input port 1b to cover the detergent input port 1b to prevent foreign materials from entering the detergent box 5.

In the embodiment of the present invention, the front side, the rear side, or the lateral side of the table 1 along the laundry inlet 1a means that, in a projection on a horizontal plane, a plane of a paper shown in fig. 4 is a horizontal plane, and an orientation with reference to the laundry inlet 1a is used.

The mesh electrode 22 and the detergent box 5 are located at different sides of the table 1 along the laundry input port 1a, which is advantageous to make full use of the installation space at the bottom side of the table 1.

Specifically, in the embodiment of the present invention, the electrolysis device 2 is located on one lateral side of the workbench 1 along the laundry feeding opening 1a, that is, the distance between the electrolysis device 2 and the detergent box 5 can be shortened, the length of the pipeline is reduced, and the structural arrangement is more reasonable under the condition of reasonable arrangement and structural distribution.

In one embodiment, referring to fig. 2 and 3, the mesh electrode 22 includes an anode 222 and a cathode 221, and the anode 222 and the cathode 221 both extend in a horizontal plane, and referring to fig. 12, the anode 222 and the cathode 221 are stacked along a height direction of the laundry treating apparatus. This enables the anode 222 and the cathode 221 to have a large electrolytic surface area without substantially affecting the size of the table 1 in the height direction of the laundry treating apparatus.

In one embodiment, referring to fig. 12, the electrolysis water outlet 21d is located above the mesh electrode 22, that is, the electrolysis water outlet 21d is higher than the cathode 221 and the anode 222. The electrolytic chamber 21a is configured such that: the water flow from the electrolysis water inlet 21c can flow to the electrolysis water outlet 21d from the lower part of the mesh electrode 22 after passing through the mesh electrode 22. That is, the liquid flow can pass through the cathode 221 and the anode 222 during flowing in the electrolytic chamber 21a, the liquid flow can timely carry away the micro-bubbles attached to the surface of the mesh electrode 22, and the water flowing from the electrolysis water outlet 21d to the storage tank 5a can be made to basically pass through the electrolyzed water electrolyzed by the mesh electrode 22, so as to ensure that the electrolyzed water entering the storage tank 5a contains more micro-bubbles and hydroxyl radicals.

When the clothes treatment equipment does not need to use the sterilization function, namely, the electrolysis device 2 does not need to be started, the water in the electrolysis cavity 21a can be emptied through the water outlet 21f, so that the water in the electrolysis cavity 21a is prevented from going bad and smelling when the washing machine is not used for a long time. The water discharged from the water outlet 21f may be discharged to the outside of the laundry treatment apparatus, or may be directly or indirectly discharged into the outer tub 61 or the inner tub 62. In the embodiment of the present invention, referring to fig. 9, the water outlet 21f and the electrolysis water outlet 21d are disposed on the same side of the housing 21, that is, the water outlet 21f is also disposed on a side of the housing 21 close to the detergent box 5; the water discharge port 21f communicates with the storage tank 5a, illustratively, through the third pipe 43, that is, the water discharged from the water discharge port 21f flows toward the detergent box 5 through the third pipe 43; the flow area of the drain port 21f is smaller than the flow area of the electrolysis water outlet 21 d. Specifically, since the water discharge port 21f and the electrolyzed water outlet 21d are provided on the same side of the case 21, that is, the water discharged from the water discharge port 21f is also electrolyzed water after being electrolyzed by the mesh electrode 22, it is ensured that the water taken into the storage tank 5a from the water discharge port 21f is also electrolyzed water after being electrolyzed; further, since the flow area of the water discharge port 21f is smaller than that of the electrolyzed water outlet 21d, the flow resistance of the liquid stream flowing from the electrolyzed water outlet 21d to the storage tank 5a is smaller than that flowing from the water discharge port 21f to the storage tank 5a, so that most of the electrolyzed water will still flow from the electrolyzed water outlet 21d to the storage tank 5a and a small portion of the electrolyzed water will flow from the water discharge port 21f to the storage tank 5 a.

When the water electrolysis is not needed, no water is fed into the electrolysis cavity 21a, the liquid level in the electrolysis cavity 21a is lowered, and when the liquid level is lower than the electrolysis water outlet 21d, the water in the electrolysis cavity 21a is discharged from the electrolysis water outlet 21d and the water is discharged from the water outlet 21f until the water in the electrolysis cavity 21a is emptied. In the embodiment of the invention, the electrolysis water outlet 21d and the water outlet 21f are arranged at the same time, so that the water flowing into the storage tank 5a is basically electrolyzed water which is fully electrolyzed, the water in the electrolysis cavity 21a can be emptied, the water in the water outlet 21f can be guided into the storage tank 5a only through a short pipeline, the structure is simple, a valve is not required, and the production and manufacturing cost can be reduced.

In an embodiment, referring to fig. 10, the housing 21 includes a housing body 211, and a first end cap 212 and a second end cap 213 hermetically disposed at two opposite ends of the housing body 211 along a length direction, the housing body 211, the first end cap 212, and the second end cap 213 together enclose a hollow accommodating space, and the electrolytic cavity 21a is at least a portion of the accommodating space. The electrolysis water outlet 21d is disposed on the first end cap 212, and the electrolysis water inlet 21c is disposed on the second end cap 213. It will be appreciated that the junction of the first end cap 212 and the housing body 211 needs to be sealingly connected to prevent water leakage, and the junction of the second end cap 213 and the housing body 211 needs to be sealingly connected to prevent water leakage.
