Description

A washing machine inner tub structure and a washing machine with the inner tub

technical field

The invention relates to the field of washing machines, in particular to an inner tub structure of a washing machine and a washing machine with the inner tub.

Background technique

There is a closed environment between the inner and outer barrels of the existing washing machine, and only water can pass through. Due to the limitations of the above-mentioned structure of the washing machine and the particularity of the use environment, after 3-5 months of use, the outer wall of the inner barrel and the outer barrel Dirt will adhere to the inner wall, thereby breeding different degrees of bacteria, and most of the bacteria that grow are harmful to the human body.

Along with the raising of people's living standard and the raising of the quality of life requirement, the solution of the hygienic problem of washing machine has shown very urgent. According to the investigation of the internal environment of the washing machine by relevant scientific research institutions, the seriousness of the internal pollution of the washing machine has been paid more and more attention by consumers. In order to fundamentally avoid the secondary dirt of the washing machine on the laundry, and be more responsible for the health of the user, the cleaning problem of the internal environment of the washing machine has become an urgent problem to be overcome.

Chinese patent 200820183308.4 discloses a washing machine with inter-tub cleaning, which includes an inner tub, an outer tub, and a plurality of circular silica gel balls for cleaning the walls of the inner and outer tubs. The silicone ball between the inner and outer tubs of the washing machine moves and constantly collides with the two walls of the inner and outer tubs to clean the inner and outer tub walls.

In addition, the applicant disclosed in Chinese application 201010160548.4 a washing machine and method using flexible particles to clean the inner and outer tubs of the washing machine. The flexible particles are driven to hit and rub against the inner and outer tub walls of the washing machine to achieve cleaning between the inner and outer tubs of the washing machine.

However, in the flange structure of the above-mentioned washing machine, there is a large water-permeable gap between the bottom of the inner tub and the flange. Although the water-permeable gap can allow the washing water to circulate between the inner tub and the outer tub, it is difficult to use flexible cleaning particles to clean the inner tub and the outer tub. For the washing machine with the barrel wall, the soft particles between the inner barrel and the outer barrel can also enter the inner barrel through the gap, thereby reducing the amount of soft particles between the inner barrel and the outer barrel, and affecting the cleaning effect of the inner barrel and the outer barrel wall.

In view of this, the present invention is proposed.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an inner barrel structure of a washing machine with cleaning particles between the inner and outer barrels to clean the barrel wall. A blocking cover is added at the bottom of the inner barrel to prevent the cleaning particles from entering Inner barrel, to avoid affecting the effect of cleaning the barrel wall.

Another object of the present invention is to provide a washing machine with an inner tub structure.

In order to solve the above-mentioned technical problems, the basic idea of the technical solution adopted by the present invention is: an inner tub structure of a washing machine, the inner tub is coaxially installed in the outer tub of the washing machine, and cleaning particles for cleaning the tub wall are arranged between the inner and outer tubs. A flange plate is installed at the bottom of the inner barrel, and the flange plate and the hollow area at the bottom of the inner barrel form a water-permeable channel. A blocking cover is provided between the bottom of the inner barrel and the flange plate to prevent cleaning particles from entering the inner barrel through the water-permeable channel. The blocking cover corresponds to The permeable passage is provided with a permeable hole.

A further solution is that the blocking cover is a hollow annular cover, the main body of the flange corresponds to the hollow position of the blocking cover, and the water permeable holes are distributed on the position of the annular cover corresponding to the permeable channel, and the main body of the flange The diameter is d, the inner diameter of the hollow area at the bottom of the inner barrel is D, the inner diameter of the blocking cover is d1, and the outer diameter is d2, satisfying d1≤d<D≤d2.

Preferably, at least two types of the blocking cover, the flange, and the bottom of the inner tub are integrally injection molded.

Alternatively, the blocking cover is an independent cover structure, the outer diameter d2 of the blocking cover is the same as the inner diameter D of the hollow area at the bottom of the inner barrel, and is snapped outside the hollow area at the bottom of the inner barrel by the engaging structure on the outside of the blocking cover.

Alternatively, the blocking cover is an independent cover structure, the outer diameter d2 of the blocking cover is larger than the inner diameter D of the hollow area at the bottom of the inner barrel, and it is sandwiched between the flange plate and the bottom of the inner barrel through the fixing feet of the flange.

A further solution of the above solution is that the blocking cover is installed on the bottom of the inner barrel and then sandwiched between the flange and the bottom of the inner barrel through the installation of the flange.

Alternatively, the blocking cover is a hollow annular cover body, the main body of the flange corresponds to the hollow position of the blocking cover, and the water permeable holes are distributed on the position corresponding to the water permeable channel of the annular cover body, and the diameter of the main body of the flange plate is d , The inner diameter of the hollow area at the bottom of the inner barrel is D, the inner diameter of the blocking cover is d1, and the outer diameter is d2, satisfying d1≤d<d2<D, and the difference between the inner diameter D of the hollow area at the bottom of the inner barrel and the outer diameter d2 of the blocking cover meets the requirements of cleaning particles The size cannot pass through the gap between the edge of the hollow area at the bottom of the inner bucket and the outer edge of the blocking cover.

In the above solution, the permeable holes are straight or curved long slit structures, such as arc or S-shaped.

Furthermore, the water permeable hole is a funnel structure that shrinks in size from top to bottom so that foreign matter such as thread scraps, buttons, coins, etc. can be discharged and can block cleaning particles.

The washing machine of the present invention comprises an outer tub, an inner tub and a pulsator. Cleaning particles for cleaning the wall of the tub are arranged between the inner and outer tubs, and a blocking cover is provided in the hollow area at the bottom of the inner tub to prevent the cleaning particles from entering the inner tub.

The cleaning granules of the present invention can float in water and impact the inner and outer barrel walls with the water flow between the inner and outer barrels of the washing machine. During the washing process of clothes, the cleaning particles are driven by the water flow to hit and rub against the inner and outer barrel walls to clean the inner and outer barrel walls of the washing machine. .

The washing machine of the present invention places cleaning particles between the inner and outer barrels to clean the walls of the inner and outer barrels, which is based on the principle that the mixture of water and solid particles moves to clean the container. In the invention, when the washing machine is assembled, as a part of the structure of the washing machine with the function of cleaning the wall of the washing machine, cleaning particles with a density close to or slightly lower than that of water are placed between the inner and outer barrels of the washing machine. During the washing process, due to the continuous forward and reverse rotation of the pulsator or the inner barrel, the water between the inner and outer barrels is exchanged with the water in the inner barrel to form a water flow, which drives the cleaning particles placed between the inner and outer barrels to swim in the water , collide with the wall between the inner and outer barrels, and at the same time clean the attachments on the inner and outer barrel walls and the bottom of the inner barrel with the aid of water soaking, fundamentally preventing the generation of dirt and the growth of bacteria.

The cleaning particles can be sponge-like substances, or rubber or plastic foams, such as foamed rubber, foamed plastics, and foamed composite polyurethane. Adsorptive materials are preferably used to make the effect of cleaning the barrel wall better , Cleaning particles must have a certain degree of elasticity, its density is smaller than water in a dry state, it has the property of soaking water in water, and the price is cheap. The above-mentioned cleaning granules should have antibacterial function and be able to resist the growth and spread of bacteria; secondly, they should have good wear resistance, and the scum and foam should not fall off during the use of the washing machine.

The above-mentioned cleaning particles placed between the inner and outer barrels can freely move between the inner and outer barrels with the water flow during washing and rinsing. Since the hollow area at the bottom of the inner barrel is provided with a blocking cover, the cleaning particles cannot enter the inner barrel from the bottom of the inner barrel. It will also not enter the lint filter with the water flow, affecting the collection of lint, ensuring the effect of cleaning the outer wall of the inner barrel and the inner wall of the outer barrel.

After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

The bottom of the inner barrel of the washing machine according to the present invention is equipped with a blocking cover, which can prevent the cleaning particles between the inner barrel and the outer barrel from entering the inner barrel through the bottom of the inner barrel, and avoid affecting the outer wall of the inner barrel and the outer barrel due to the reduction of cleaning particles between the inner barrel and the outer barrel The cleaning effect of the inner wall; the permeable holes distributed on the blocking cover will not affect the circulation of washing water between the inner tub and the outer tub, and will not be blocked by lint; the invention has a simple structure and low installation cost.

The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
