BACKGROUND

According to a household electric full-automatic washing machine, an inner barrel is provided in an outer barrel, and its working process is that after laundry is put into the inner barrel and the water is fed into the barrel and the detergent is added, the washing, rinsing and dehydration processes are automatically performed. The washing machine barrel is in constantly contact with the washing water, the laundry, the thread scraps and so on during the using, and the washing machine is usually placed in a damp, poorly ventilated toilet, the fouling is inevitably gathered between the inner and outer barrel during a prolonged using. For the existing washing machine, the gap between the inner and outer barrel is small, and the upper part of the outer barrel is provided with an outer barrel cover, so that it is hard for the user to clean the inner barrel. Therefore, after a long-time use, the fouling in the inner barrel will further breed molds and bacteria, which will not only affect the washing effect of the laundry, but also cause a secondary pollution and affect the health of the user.
One existing coping method is to place rubber ball particles between the inner and outer barrel. A Chinese patent No.200820183308.4 discloses a “barrel set washing machine with an inter-barrels cleaning function”. A plurality of circular silica gel balls are placed between the inner and outer barrel, and the inner barrel of the washing machine is used to rotate the water so as to drive the silica gel ball between the inner barrel and the outer barrel of the washing machine and continuously collide with the inner and outer barrel walls to achieve the purpose of cleaning the inner and outer barrel walls. The density of the rubber ball particles is comparable to or slightly less than the density of the water. When the washing machine is subjected to the routine washing by the users, the rubber ball particles float in the water, and collide with the outer wall of the inner barrel and the inner wall of the outer barrel during the washing process, which can effectively remove the fouling.
Moreover, in order to improve the strength of the washing machine inner barrel, the inner barrel bottom is generally provided with a plurality of reinforcing ribs. These reinforcing ribs are intersected with each other to form a lot of grooves on the inner barrel bottom. Because of the existence of the groove structure, it is highly easier for the fouling to being accumulated here. Furthermore, the groove structures are a lot in number and small in size, when adopting the rubber ball particles to cleaning the barrel wall, the rubber ball particles cannot enter into the groove structures at all, and the cleaning of the inner barrel bottom cannot be realized, the cleaning effect is affected.
A Chinese utility model patent NO.201120554753.9, entitled washing machine inner barrel and washing machine, is to provide a washing machine inner barrel, comprising a balance ring, a barrel body and a barrel bottom, and a protective cover is mounted on the barrel bottom. The protective cover is made by a ring-shaped upright sidewall and a flat bottom surface with a drainage hole. The protective cover sidewall is located outside the barrel bottom sidewall, and the protective cover and the inner barrel bottom are connected by a screw or by clamping. The utility model patent also relates to a washing machine using the self-cleaning function of the washing machine inner barrel structure. The protective cover is arranged on the bottom of the washing machine inner barrel of the utility model patent, effectively preventing the rubber ball from entering the groove of the inner barrel bottom. The cleaning effect of the rubber particles on the inner and outer barrel wall is improved, meanwhile, the noise caused by the collision of the rubber ball and the inner barrel during the dehydration is reduced, and the washing machine product quality is improved.
In the above utility model patent, the protective cover is installed on the bottom of the washing machine inner barrel, preventing the rubber ball from entering into the groove, making sure the cleaning effect of the barrel wall, and avoiding the noise caused by the collision of the rubber ball during the dehydration. However, the protective cover is provided with the drainage hole, the washing water will still enter into the groove and the fouling will be produced in the groove. Once the fouling is produced, it is hard or impossible to be cleaned.
In view of this, the present disclosure is proposed.
