The following describes an example in which the electrolysis apparatus is applied to a laundry treating apparatus.

In another aspect of the embodiments of the present application, there is provided a laundry treatment apparatus comprising a cartridge assembly and any one of the above-described electrolytic devices.

The specific type of the laundry treating apparatus is not limited, and may be, for example, a drum type washing machine, a pulsator type washing machine, a washing and drying integrated machine, etc., and is not limited herein.

The drum assembly has a laundry treating cavity. The top side of the laundry treating chamber is opened, and a user takes and puts laundry in the laundry treating chamber from above the laundry treating chamber. That is, the drum assembly serves to provide a space for laundry as well as the treatment of the laundry.

Illustratively, in some embodiments, the drum assembly includes an outer drum that is nested outside of an inner drum for containing water for washing the laundry, and an inner drum for containing the laundry, that is, the inner drum is formed with a laundry treatment cavity, in which embodiment the inner drum contains water through the outer drum, which may also be referred to as a perforated inner drum. In other embodiments, the inner cylinder can hold water by itself and can also be called a non-porous inner cylinder, and the outer part of the inner cylinder can be provided with or without an outer cylinder.

Illustratively, the laundry treatment apparatus comprises a table disposed above the drum assembly, the table being provided with a laundry input opening located above the laundry treatment chamber through which a user may take and place laundry.

The clothes treatment equipment is provided with a water inlet waterway, the water inlet waterway is used for supplying water for the barrel assembly, and the electrolysis device is arranged on the water inlet waterway. That is, at least a portion of water (e.g., tap water) from the external water source is electrolyzed by passing through the electrolysis apparatus, and the electrolyzed water is then contacted with the laundry.

Illustratively, the housing 1 has a water inlet 1b (see fig. 9) and a water outlet 1c (see fig. 7 and 8). The runner 1a is communicated with the water inlet 1b and the water outlet 1c, and the water outlet 1c is used for discharging water to a clothes treatment cavity of the clothes treatment equipment. Specifically, a water inlet waterway is communicated with the water inlet 1b, and the water inlet waterway is used for guiding an external water source into the housing 1, for example, one end of the water inlet waterway is connected with a tap water pipe, and the other end is connected with the water inlet 1b.

It will be appreciated that a water inlet valve may be provided on the water inlet path or at the water inlet 1b to facilitate control of the on-off of the water flow through the water inlet valve.

It should be noted that, in some embodiments, the water from the external water source flows through the electrolysis device entirely; in other embodiments, the external water source is divided into at least two water inlet waterways, wherein a part of the water inlet waterways are provided with the electrolysis device, and the rest of the water inlet waterways are not provided with the electrolysis device, so that the water inlet efficiency can be considered.

The water from the water inlet channel may be directly injected into the laundry treating chamber or directly injected between the outer tub and the inner tub.

In addition, because the electrode assembly 2 does not need to contact washing water in the clothes treatment cavity, sundries such as flocks and hairs can not be attached to the electrode assembly 2, and the service life of the electrode assembly 2 can be prolonged.

In the water injection process of the electrolysis device, the flow rate of water flow is large, the water flow is used for strongly flushing the electrode assembly 2, and the probability of adhering scale to the surface of the electrode assembly 2 is reduced; the water flow can wash out the micro-bubbles generated on the surface of the electrode assembly 2 in time, so that the micro-bubbles are prevented from gathering and growing up, the washing effect can be improved, and the generation of scale can be restrained. Therefore, the electrolytic device provided by the embodiment of the application can effectively improve the scaling phenomenon of the surface of the electrode assembly 2 and prolong the service life of the electrode assembly 2.

In one embodiment, the laundry treatment apparatus comprises a detergent box for dosing detergent into the housing 1. The types of detergents are not limited, and may be granular substances such as washing powder, fluid substances such as washing machine, softener, disinfectant, and the like, or laundry detergent beads, for example.

It will be appreciated that a detergent box is provided within the mixing chamber 1f.

Illustratively, the mixing chamber 1f is adapted to direct a mixture of water and detergent to the water outlet 1c. The detergent and water are mixed in the mixing chamber 1f, and the mixed solution flows from the water outlet 1c to the laundry treating chamber. 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. 7, the edge of the bottom surface of the mixing chamber 1f forms the water outlet 1c. Specifically, the water flows along the bottom surface of the mixing chamber 1f and flows out from the rim, and then flows to the laundry treating chamber below.

Illustratively, the bottom surface of the mixing chamber 1f is inclined downward toward the water outlet 1c, so that a good flow guiding effect can be achieved, and water accumulation in the mixing chamber 1f is avoided.

In some embodiments, referring to fig. 6 to 7, a drawing port 1e is disposed at one side of the mixing chamber 1f, and the mixing chamber 1f is configured to drawably receive the detergent box, that is, the detergent box is drawably disposed in the mixing chamber 1f, 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 1f. 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 1e, and after the detergent is added to the detergent box, the detergent box is pushed into the mixing chamber 1f.

In some embodiments, the drawing port 1e 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 1e, so that a user can conveniently add detergent.

The operation principle of the electrolysis apparatus in the laundry treating apparatus is briefly described as follows.

When the laundry treating apparatus is operated, the electrolysis means is started, the cathode 21 and the anode 22 are energized, and after the energization, the electrode assembly 2 may start to electrolyze water. The water used for washing clothes in the clothes treatment equipment is electrolyzed by the electrode assembly 2 to generate hydroxyl free radicals (-OH) with strong oxidability, the OH has extremely high oxidation potential (2.80 eV), the oxidation capacity of the OH is extremely high, the OH can carry out quick chain reaction with most organic pollutants, the OH can be sterilized and disinfected at low temperature, the clothes are not damaged, a part of the OH reacts with chlorine molecules in tap water to produce active chlorine, and the active chlorine can exist for a long time and has long-term bacteriostasis effect; the free dye is prevented from being stained into light-colored clothes to cause cross color, and the dye molecules are decomposed into harmless carbon dioxide, water and inorganic salt by continuing the reaction. Meanwhile, the electrode assembly 2 can generate a large amount of micro bubbles, and the diameter of the micro bubbles is very small and is usually smaller than 50um (micrometers), so that the micro bubbles can well enter the inside of the clothes fiber in the washing process, and the micro bubbles are continuously generated to circularly wash through the actions of blasting and adsorbing floating of the micro bubbles, so that the detergent can assist the detergent to thoroughly remove sebum, grease, tiny dust and other dirt accumulated in the clothes fiber, and the washing effect can be improved.

In order to improve the cleaning effect, the electrolyzed water contains more hydroxyl radicals, active chlorine, microbubbles and the like, and in some embodiments, a plurality of through holes penetrating through the cathode 21 and the anode 22 along the thickness direction of the cathode 21 and the anode 22 are formed on the cathode 21 and the anode 22, on one hand, the electric charge density at the junction between the inner wall of the through hole and the surfaces of the cathode 21 and the anode 22 is relatively high, the electric field strength near the through holes is relatively high, the electrolysis efficiency can be greatly improved, more hydroxyl radicals, active chlorine and other active substances can be generated, and meanwhile, more microbubbles can be generated, so that the sterilization and washing effects can be improved; on the other hand, the water flow can flow from one side of the cathode 21 and the anode 22 to the other side of the cathode 21 and the anode 22 through the through holes, and the water flow can timely take away micro bubbles on the surfaces of the cathode 21 and the anode 22 and the inner wall surfaces of the through holes, so that the micro bubbles are prevented from being aggregated to form large bubbles.

The shape and size of the through hole are not limited, and may be circular, elliptical, polygonal, or the like, for example. Illustratively, the through holes are circular, the diameter of the through holes ranges from 2mm to 5mm, on one hand, microbubbles are convenient to form at the through holes, and on the other hand, microbubbles are convenient to separate from the surfaces of the cathode 21 and the anode 22, specifically, if the diameter of the through holes is too large, the number of the microbubbles will be small under the condition that the area and the shape of the cathode 21 and the anode 22 are not limited, the number of the microbubbles will be small, if the diameter of the through holes is too small, the tip area of the edges of the through holes is small, the microbubbles are not easy to generate, the generated microbubbles are difficult to quickly overflow in the through holes, and are easy to aggregate and grow into large bubbles in the through holes.
