The detergent box is used for throwing detergent into the spray head body 2, and the spray head body 2 is used for guiding water into the detergent box so that the water in the detergent box flows into the clothes treatment cavity after being mixed. The electrolysis assembly 1 comprises a cathode 12 and an anode 11, the cathode 12 and the anode 11 being arranged in the flow channel for electrolysis of water flowing through the flow channel. That is, the electrolytic assembly 1 has no additional housing, and the cathode 12 and the anode 11 are directly exposed to the flow path of the showerhead body 2. The clothes treatment device can electrolyze water while injecting water into the clothes treatment cavity, so that the water injected into the clothes treatment cavity is electrolyzed water, and overcurrent electrolysis is realized.

In some embodiments, referring to fig. 11 to 12, the cathode 12 includes at least two cathode sheets 121, the anode 11 includes at least one anode sheet 111, the cathode sheets 121 and the anode sheets 111 are stacked, and one anode sheet 111 is disposed between two adjacent cathode sheets 121.

Wherein the stacked arrangement means that the plate surfaces are arranged substantially parallel to each other and facing the plate surfaces.

In other embodiments, referring to fig. 13, the anode 11 is cylindrical and the cathode 12 surrounds the anode 11.

In the clothes treatment equipment provided by the embodiment of the application, the electrolysis assembly 1 can be started in the water injection process, and ozone water can be generated by utilizing oxygen in water in the water electrolysis process of the electrolysis assembly 1, and as the oxygen in water is activated in the electrolysis process, the oxygen in water is inexhaustible, so that the efficiency of ozone generation is high, ozone has a sterilizing effect, and ozone can exist in water for a period of time, so that the ozone generated by the electrolysis of water can sterilize or antibacterial clothes or the clothes treatment equipment; in addition, hydroxyl free radicals (OH) with strong oxidation activity can be generated in the electrolysis process, the OH has extremely high oxidation potential (2.80 eV), the oxidation capability is extremely strong, the hydroxyl free radicals can react with most organic pollutants rapidly, the OH can be sterilized and disinfected at low temperature, the clothes are not damaged, part of the OH reacts with chlorine water in tap water to generate active chlorine, and the active chlorine can exist for a long time and has long-term bacteriostasis effect; multiple antibacterial molecules exist in the electrolyzed water at the same time, so as to achieve the effect of multiple bacteriostasis. The electrolysis assembly 1 generates a large amount of ozone in the electrolysis process, can oxidize and destroy the chromophoric groups of dye molecules in which colored clothes are dissociated into water in the washing process to decolorize the dye, prevents the dissociated dye from being stained into light-colored clothes to cause cross color, and continuously reacts to decompose the dye molecules into harmless carbon dioxide, water and inorganic salt; the generated hydroxyl radical can decompose dye molecules on the surface of the electrode (or near the electrolytic device), so that the color-mixing prevention effect is better. Meanwhile, the electrode can generate a large amount of hydrogen microbubbles, the diameter of the microbubbles is very small and is usually smaller than 50um, the microbubbles can well enter the inside of the clothing fiber in the washing process, and the microbubbles are continuously generated to circularly wash through the actions of blasting and adsorbing and floating the microbubbles, so that the detergent is assisted to thoroughly remove the sebum, grease, tiny dust and other dirt accumulated in the clothing fiber, and the washing effect can be improved.

According to the first spray head body device, the cathode sheets 121 and the anode sheets 111 are stacked, and one anode sheet 111 is arranged between two adjacent cathode sheets 121, so that the surfaces of two sides of the anode sheet 111 can participate in electrolysis, the metal catalyst surface on the surface of the anode sheet 111 is fully utilized, the electrolysis efficiency is improved, and the cost is saved.

According to the second spray head body device, the anode 11 is columnar, the cathode 12 surrounds the anode 11, and therefore the arrangement mode that the cathode 12 surrounds the anode 11 can maximize the surface area of electrolysis in a narrow space and improve the electrolysis efficiency.

Secondly, in the two spray head body devices of the embodiment of the application, the electrolytic assembly 1 is arranged in the flow channel of the spray head body 2, so that the space of the spray head body 2 can be fully utilized, an additional shell is not required to be configured for the electrolytic assembly 1, and the structure is compact; in addition, the shower nozzle body 2 sets up in the top of barrel subassembly, both be convenient for install, be convenient for maintenance operation again.

In addition, since the electrolytic assembly 1 does not need to contact the washing water in the laundry treating chamber, foreign matters such as flock, hair, etc. are not attached to the electrolytic assembly 1, and the service life of the electrolytic assembly 1 can be improved.

In the water injection process of the nozzle body, the flow rate of water flow is large, the water flow is used for strongly flushing the electrolytic assembly 1, and the probability of adhering scale to the surface of the electrolytic assembly 1 is reduced; the water flow can wash out the micro-bubbles generated on the surface of the electrolytic component 1 in time, so as to prevent the micro-bubbles from gathering and growing up, thereby improving the washing effect and being beneficial to inhibiting the generation of scale. Therefore, the nozzle body device of the embodiment of the application can effectively improve the scaling phenomenon of the surface of the electrolytic component 1 and prolong the service life of the electrolytic component 1.

The specific structure of the cathode 12 is not limited.

In some embodiments, the number of cathode sheets 121 of the cathode 12 is two, the number of anode sheets 111 of the anode 11 is one, and the two cathode sheets 121 are formed by bending the same metal plate. In this way, the material and cost for manufacturing the cathode 12 are saved, and in addition, the two cathode tabs 121 are formed by bending the same metal plate, which can be accomplished by one process or fewer process steps, which contributes to an improvement in production efficiency. The fabrication process of the integrated structure is simpler and faster than assembling the multiple component structure.

In other embodiments, each of the cathode sheets 121 of the cathode 12 is of a split construction.

Illustratively, referring to fig. 12, the electrolytic assembly 1 includes a conductive connecting member 13, the anode tab 111 is provided with a first through hole, the cathode tab 121 of the cathode 12 is provided with a second through hole, and the conductive connecting member 13 passes through the first through hole and the second through hole to electrically connect the respective cathode tabs 121.

Wherein the conductive connection member 13 and the anode tab 111 are electrically insulated, and the conductive connection member 13 is in conductive contact with the cathode tab 121.

In this embodiment, when the flow path space is large, the assembly of the plurality of cathode tabs 121 and anode tabs 111 is facilitated, and the plurality of cathode tabs 121 and anode tabs 111 can be connected through the conductive connection member 13 to improve the electrolysis efficiency.

Illustratively, cathode 12 includes a cathode terminal 122 and anode 11 includes an anode terminal 112. The cathode tab 121 is connected to the cathode connection terminal 122, the anode tab 111 is connected to the anode connection terminal 112, and it is understood that the cathode tab 121 is electrically connected to the cathode connection terminal 122, and the anode tab 111 is electrically connected to the anode connection terminal 112.

It will be appreciated that the cathode terminal 122 is connected to the negative line of the power line and the anode terminal 112 is connected to the positive line of the power line.

When water is electrolyzed, the cathode 12 generates a reduction reaction, namely hydrogen ions generated by ionization balance of the water are attracted by charges of the cathode 12 to migrate towards the cathode 12, electrons are received on the cathode 12 to separate out hydrogen, the anode 11 generates an oxidation reaction, namely hydroxyl ions generated by ionization balance of the water are attracted by the anode 11 to migrate towards the anode 11, bond breaking occurs at the anode 11, and oxygen is separated out.

For example, referring to fig. 14, the portion of the cathode 12 for connecting the two cathode sheets 121 is a bent edge 12a, the cathode connecting terminal 122 is disposed at one end of one of the cathode sheets 121 away from the bent edge 12a and extends in a direction away from the bent edge 12a, and the anode connecting terminal 112 is disposed at one end of the anode sheet away from the bent edge 12a and extends in a direction away from the bent edge 12 a. It will be appreciated that the arrangement of the cathode connection terminal 122 and the anode connection terminal 112 away from the crimp 12a reduces the required length of the power cord, facilitating routing of the electrolytic assembly 1 to the power cord.

It will be appreciated that the cathode 12 and the anode 11 are insulated from each other, i.e. any position of the cathode 12 and the anode 11 is not contacted, so that the normal operation of the spray head body device is ensured.

Illustratively, the electrolytic assembly 1 includes an insulating connection member through which the anode sheet 111 is provided with a first connection hole and the cathode sheet 121 is provided with a second connection hole to connect the cathode 12 and the anode 11 together. In this way, the short circuit risk of the electrolysis assembly 1 is reduced, and the efficiency and stability of the water electrolysis reaction of the nozzle body device are improved.

It is understood that the shape and configuration of the insulating connector are not limited as long as the cathode 12 and the anode 11 can be effectively isolated, and the insulating connector may be made of a material having a certain damping property, for example, rubber, silica gel, etc.

Referring to fig. 5 and 6, the spray head body 2 includes a spacing rib 2111, and the spacing rib 2111 divides a portion of the flow path into a drainage area 2c and a water diversion area, and the drainage area 2c is a portion of the flow path and the water diversion area is a portion of the flow path. Wherein the drainage zone 2c is located upstream of the water diversion zone, i.e. the water flow first passes through the drainage zone 2c and then through the water diversion zone. The water inlet 2a is arranged at one end of the drainage area 2c, and the spacing ribs 2111 are used for guiding water flow to the water diversion area.

The electrolytic component 1 is arranged in the drainage area 2c, and the water inlet 2a is arranged at the upstream end of the drainage area 2c.

In this embodiment, the water flowing to the water division region can be subjected to electrolysis by the electrode assembly 1, so that the content of the electrolytically-active species in the water at each portion of the water division region is relatively uniform.

Illustratively, the spacing ribs 2111 extend in the second direction in fig. 6, with the drainage and water diversion regions 2c located on opposite sides of the spacing ribs 2111. For example, the water diversion area is located on the front side of the spacer ribs 2111 as shown in fig. 6, and the drainage area 2c is located on the rear side of the spacer ribs 2111 as shown in fig. 6.

For example, referring to fig. 5 and 6, a communication port 2h is formed between the drainage area 2c and the water diversion area. The communication port 2h is the junction between the drainage area 2c and the water diversion area. The water in the drainage area 2c is guided to the water diversion area through the communication port 2h.

Illustratively, the spray head body assembly includes a mixing chamber 2f, the mixing chamber 2f being disposed downstream of the flow-directing region 2c in the direction of flow of the water stream, that is, the water stream flows through the flow-directing region 2c before flowing through the mixing chamber 2f.

The mixing chamber 2f is used to guide the mixed liquid of water and detergent to the water outlet 2b.

In the prior art, because the electrolytic component is contacted with the detergent in the working process, the current of the electrolytic component is increased, the scaling process is accelerated, and the service life of the electrolytic component is influenced, the electrolytic component 1 is positioned at the upstream of the mixing cavity 2f, so that the contact of the electrolytic component and the detergent is avoided, the working environment of the electrolytic component 1 is greatly improved, and the service life of the electrolytic component 1 is prolonged.

Illustratively, with continued reference to fig. 3, the edge of the bottom surface of the mixing chamber 2f forms the water outlet 2b. Specifically, the water flows along the bottom surface of the mixing chamber 2f and flows out from the rim, and then flows to the laundry treating chamber below.

Illustratively, the bottom surface of the mixing chamber 2f is inclined downward toward the water outlet 2b, so that a good flow guiding effect can be achieved, and water accumulation in the mixing chamber 2f is avoided.

The manner of injecting the detergent into the mixing chamber 2f is not limited.

For example, referring to fig. 3, a drawing port 2k is provided on one side of the mixing chamber 2f, and the mixing chamber 2f is configured to drawably receive the detergent box, that is, the detergent box is drawably disposed in the mixing chamber 2f, and the water flow in the flow channel flows at least partially through the detergent box to carry the detergent in the detergent box to the bottom surface of the mixing chamber 2f. In this example, the detergent is manually administered.

When the detergent is required to be added, the detergent box is drawn out from the drawing port 2k, and after the detergent is added to the detergent box, the detergent box is pushed into the mixing chamber 2f.

In some embodiments, the drawing port 2k is communicated with the clothes putting port of the workbench, and the detergent box stretches into the clothes putting port after being drawn out from the drawing port 2k, so that a user can conveniently add detergent.

The specific structure of the head body 2 is not limited.

Referring to fig. 1, 7 and 9, the spray head body 2 includes a bottom case 21 and a top cover 22, and the top cover 22 covers the top side of the bottom case 21.

The connection between the bottom case 21 and the top cover 22 is not limited, and may be detachable or non-detachable. By way of example, ultrasonic welding, laser welding, screw connection, bonding, riveting, etc. may be used.

For example, referring to fig. 2 and 3, bottom shell 21 includes a top wall 211, a bottom wall 212, and side walls 213. The side enclosure walls 213 connect the top wall 211 and the bottom wall 212, the top wall 211, the bottom wall 212 and the side enclosure walls 213 defining the mixing chamber 2f. For example, top wall 211 is generally plate-like in configuration, and bottom wall 212 and side wall 213 are also generally plate-like in configuration. The top cover 22 covers the top side of the top wall 211.

An edge of one side of the bottom wall 212 forms the water outlet 2b.

The drainage area 2c is located on the top surface of the top wall 211, i.e. the drainage area 2c is located on the side of the top wall 211 facing the top cover 22.

The nozzle body 2 in this embodiment has at least two layers of spaces along the height direction, the lower layer space is a mixing cavity 2f formed between the top wall 211, the bottom wall 212 and the side wall 213, and the upper layer space is a space formed between the top wall 211 and the top cover 22. The water flow flows from the upper space to the lower space, has a certain fall, has a better scouring effect on the detergent, and improves the dissolution effect of the detergent.

Illustratively, the electrolytic assembly 1 is disposed on the top side of the top wall 211. The electrolytic assembly 1 does not protrude into the mixing chamber 2f and therefore does not come into contact with the detergent and, furthermore, does not affect the dosing of the detergent.

For example, referring to fig. 4, 5 and 8, the top surface of the top wall 211 further has a spraying area 2d, and the spraying area 2d is located downstream of the drainage area 2c in the water flow direction, that is, the water flows through the drainage area 2c first and then through the spraying area 2d.

The spraying region 2d is provided with a plurality of water passing holes 2e penetrating the top wall 211, the water passing holes 2e for spraying water to the mixing chamber 2f below. The spraying area 2d can enable water flow to the mixing cavity 2f below in a dispersing manner as much as possible, and the water outlet effect of the shower head is similar, so that the washing effect of the water flow on the detergent can be improved, and the dissolution of the detergent is promoted.

The spraying area 2d is not limited to be formed, for example, a plurality of rib structures are disposed on the top surface of the top wall 211, and the plurality of rib structures enclose the spraying area 2d on the top surface of the top wall 211.

Referring to fig. 4, 5 and 8, the number of spraying areas 2d is plural, each spraying area 2d is provided with a plurality of water passing holes 2e, and water flowing out of the drainage area 2c can flow to any one spraying area 2d. It should be noted that the water flowing out of the drainage area 2c does not flow to the rest of the area except the spraying area 2d.

Illustratively, the water inlet 2a is provided on a side wall of the drainage area 2c in the second direction, for example, on a right side wall in the left-right direction of fig. 6. The first direction, the second direction and the height direction of the nozzle body device are mutually perpendicular.

The drainage area 2c extends in the second direction, that is, the drainage area 2c extends substantially in the right-left direction of fig. 6, and the water flow flows in the drainage area 2c substantially in the right-left direction of fig. 6.

The water of the water supply line enters the drainage area 2c through the water inlet 2a, flows in the direction from right to left in the drainage area 2c, then flows to the front spraying area 2d, is sprayed to the lower mixing chamber 2f through the water hole 2e, and the detergent and the water are mixed in the mixing chamber 2f and flow from the water outlet 2b to the laundry treating chamber.

In some embodiments, referring to fig. 1 and 7, the cathode terminal 122 and the anode terminal 112 sealingly pass through the top cover 22. The use of the top cover 22 to directly or indirectly fix the cathode connection terminal 122 and the anode connection terminal 112 can serve to fix the cathode 12 and the anode 11, and in addition, facilitate the connection operation of the operator during the installation process. In addition, the connection between the cathode connecting terminal 122 and the top cover 22 and the connection between the anode connecting terminal 112 and the top cover 22 are all located above the drainage area 2c and are not soaked by water, so that the sealing requirement on the connection can be reduced, and the waterproof sealing performance is good.

For example, referring to fig. 3, a plurality of clamping grooves 221 are formed on a side of the top cover 22 facing the bottom case 21, and the top ends of the cathode sheets 121 and the top ends of the anode sheets 111 are clamped into the corresponding clamping grooves 221.
