Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes processing equipment, and particularly relates to a clothes processing equipment. BACKGROUND

[0002] With the improvement of people's living standards, various intelligent devices are widely used in all aspects of people's life. Taking a washing machine as an example, as one of the indispensable household appliances in modern families, the functions of the washing machine are becoming more and more diversified, trying to meet the various needs of users as much as possible.

[0003] The washing mode of the traditional washing machine is to form a mixed liquid by water flow impacting washing liquid or washing powder, and then add it into the washing barrel. Due to the influence of external temperature and washing liquid activity, a long time is needed to completely dissolve the washing liquid into water and start effective washing. The low-efficiency washing mode before this also consumes corresponding energy and time, resulting in that the clothes cannot be washed clean even after a long time of washing. Moreover, the existing washing machines mostly add an appropriate amount of washing liquid or washing powder before washing starts, and cannot provide circulating and fully mixed washing liquid for a long time, resulting in poor washing effect.

[0004] In addition, the traditional washing machine does not have the function of recycling washing sewage, thereby causing the problem of large water consumption for washing clothes. The prerequisite for recycling washing sewage is to purify the washing sewage. The existing purification method mostly adopts chemical purification method, that is, by adding chemical reagents to react with pollutants in the washing sewage, so as to achieve the effect of purifying water quality. However, such purification method often has chemical residues, which will cause adverse effects on human body for a long time.

[0005] Therefore, how to optimize the purification of washing sewage so that it can be recycled and also provide circulating and fully mixed washing liquid for a long time is a problem to be solved.

[0006] Therefore, the present application is proposed. SUMMARY

[0007] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art, and to provide a clothes processing equipment. By providing a liquid adding device on the circulating pipeline, circulating washing water can provide circulating and uniformly mixed washing liquid to the washing barrel for a long time, effectively improving the washing effect of clothes. At the same time, a purification device is provided on the circulating pipeline to purify and reuse the washing water, effectively saving water resources.

[0008] To solve the above technical problems, the basic idea of the technical solution of the present application is as follows: a clothes processing equipment, comprising:

[0009] A circulation pipeline, one end of which is communicated with the drain port of the washing barrel, and the other end of which is communicated with the water inlet port of the washing barrel;

[0010] A liquid adding device, which is communicated with the circulation pipeline, and is used for adding washing liquid into the circulation pipeline;

[0011] A purification device, which is arranged on the circulation pipeline and is located downstream of the liquid adding device, is used for separating and discharging the contaminant particles in the washing water, and obtaining and conveying the purified water containing the washing agent into the washing barrel.

[0012] In the above scheme, the purification device is arranged downstream of the liquid adding device, and the purification device is used for purifying the washing water to which the washing liquid is added, and can further promote the mixing and foaming of the washing liquid and the washing water, and improve the washing effect.

[0013] Further, a part of the circulation pipeline is reduced in diameter to form a Venturi structure, and the liquid adding device is communicated with the Venturi structure.

[0014] In the above scheme, when the washing water flows through the Venturi structure, the Venturi effect is generated, i.e. when the washing water flows through the Venturi structure, a low pressure area is generated near the Venturi structure, thereby generating the adsorption effect.

[0015] Further, the liquid adding device comprises:

[0016] A liquid storage box, which is used for storing the washing liquid;

[0017] A liquid adding pipeline, one end of which is communicated with the liquid storage box, and the other end of which is communicated with the negative pressure area of the Venturi structure.

[0018] In the above scheme, the liquid adding device is communicated with the Venturi structure of the circulation pipeline through the liquid adding pipeline, when the washing water flows through the Venturi structure, the Venturi effect is generated, and the washing liquid in the liquid storage box is automatically siphoned into the circulation pipeline under the negative pressure, and the washing liquid is uniformly mixed with the washing water in the circulation pipeline during the flowing process, thereby playing a role of pre-mixing the washing liquid.

[0019] Further, the purification device comprises:

[0020] A liquid inlet pipeline, which is communicated with the circulation pipeline;

[0021] A rotating stirrer, which is rotatably arranged in the liquid inlet pipeline, and is used for stirring the washing water;

[0022] A cyclone separation pipeline, which is communicated with the liquid inlet pipeline, and is used for separating the contaminant particles in the washing water to obtain the purified water containing the washing agent;

[0023] A pollution discharge pipeline, which is communicated with the cyclone separation pipeline, and is used for discharging the contaminant particles;

[0024] A recovery pipeline is in communication with the cyclone separation pipeline at one end and with a water inlet of the washing tub at the other end, for conveying the purified water containing the detergent into the washing tub.

[0025] In the above scheme, the washing water separates the contaminant particles by the action of cyclone separation, thereby obtaining purified water containing the washing liquid. This purification method belongs to pure physical purification, without using any chemical reagent and without chemical reaction, avoiding chemical residue, being more healthy, and having short purification time, good purification effect and high efficiency compared with the chemical purification method.

[0026] Meanwhile, the washing liquid and the washing water are mixed more fully under the stirring action of the rotating stirrer in the purification process, promoting foaming, and the purified water containing the detergent foam can perform intensive washing on the clothes after entering the washing tub, greatly improving the washing effect.

[0027] Further, a plurality of spiral ribs are arranged on the outer surface of the rotating stirrer, the ribs protrude from the outer surface of the rotating stirrer, and the ribs are arranged at intervals to form water flow channels between adjacent ribs.

[0028] In the above scheme, when the rotating stirrer rotates, the washing water flows through the water flow channels formed between adjacent ribs and is transported to the cyclone separation pipeline under the rotating action of the rotating stirrer to form a cyclone, thereby achieving the effect of separating contaminant particles.

[0029] Further, the rotating stirrer is located at the communication position of the liquid inlet pipeline and the cyclone separation pipeline, the axial direction of the rotating stirrer is the same as the axial direction of the liquid inlet pipeline, and the rotating stirrer can rotate axially.

[0030] The outer surface of the rotating stirrer and the inner surface of the liquid inlet pipeline have a gap therebetween.

[0031] In the above scheme, the rotating stirrer is arranged to rotate axially, so that the washing water forms a cyclone under the stirring action of the rotating stirrer and flows along the axial direction of the liquid inlet pipeline without splashing everywhere, improving the separation effect of contaminant particles.

[0032] Further, the rotating stirrer is provided with an axial channel penetrating the rotating stirrer, one end of the channel is in communication with the cyclone separation pipeline, and the other end is in communication with the recovery pipeline.

[0033] Further, the liquid inlet pipeline is provided with a mounting port, and the recovery pipeline is rotatably arranged at the mounting port.

[0034] Further, the diameter of the cyclone separation pipeline gradually decreases along the water flow direction.

[0035] In the above scheme, the rotating washing water, after entering the cyclone separation pipeline, is thrown to the inner wall of the cyclone separation pipeline due to the centrifugal force generated by rotation, and is driven by a small amount of washing water to enter the sewage pipeline and be discharged from the laundry treatment equipment.

[0036] The purified water containing washing liquid is gathered at the center of the cyclone separation pipeline under the action of centrifugal force, and as the diameter of the cyclone separation pipeline gradually decreases along the water flow direction, the resistance and pressure of the purified water flow become larger and larger, and in addition to the continuous inflow of subsequent washing water, the purified water containing washing liquid forms a reverse flow, enters the recycling pipeline through the channel of the rotating stirrer, and then flows into the washing tub from the water inlet of the washing tub for reuse.

[0037] Further, a booster pump is arranged on the circulating pipeline upstream of the Venturi structure to provide power for the accelerated circulating flow of washing water.

[0038] After adopting the above technical scheme, the present application has the following beneficial effects compared with the prior art:

[0039] By arranging the liquid adding device on the circulating pipeline, the present application can provide long-term circulating and uniformly mixed washing liquid to the washing tub by using the circulating washing water, effectively improving the washing effect of the laundry, and by arranging the purification device on the circulating pipeline, the washing water is purified and reused, effectively saving water resources.

[0040] In the present application, the purification device is arranged downstream of the liquid adding device, which purifies the washing water added with washing liquid, and further promotes the mixing and foaming of the washing liquid and washing water, improving the washing effect.

[0041] In the present application, the liquid adding device is in communication with the Venturi structure of the circulating pipeline through the liquid adding pipeline, and when the washing water flows through the Venturi structure, the Venturi effect is generated, and the washing liquid in the liquid storage box is automatically siphoned into the circulating pipeline under negative pressure, and in the flowing process, the washing liquid is uniformly mixed with the washing water in the circulating pipeline, playing a role of pre-mixing the washing liquid.

[0042] In the present application, the washing water separates and discharges the pollutant particles through the action of cyclone separation, so as to obtain purified water containing washing liquid, and this purification method belongs to pure physical purification, without using any chemical reagent and without chemical reaction, avoiding chemical residue, being more healthy compared with the chemical purification method, and having short purification time, good purification effect and high efficiency.

[0043] In the purification process of the present application, the washing liquid is mixed with the washing water more fully under the stirring action of the rotating stirrer, promoting the foaming, and the purified water containing washing liquid foam can perform intensive washing on the laundry after entering the washing tub, greatly improving the washing effect.

[0044] The present application sets several helically arranged ribs on the outer surface of the rotating stirrer, when the rotating stirrer rotates, the washing water flows through the water flow channel formed between adjacent ribs, and is transported to the cyclone separation pipeline under the rotation of the rotating stirrer, forming a cyclone body, so as to achieve the effect of separating the pollutant particles.
