Title: Washing machine

Description:
TECHNICAL FIELD 
     The present disclosure belongs to the technical field of washing equipment, and in particular relates to a washing machine. 
     BACKGROUND ART 
     A traditional fully automatic wave-wheel washing machine generally includes an inner barrel, an outer barrel, a damping part and a power system. During clothes washing and dehydrating, the inner barrel rotates relative to the outer barrel, such that clothes interact with washing water and the purpose of cleaning clothes or dehydrating is achieved. The outer barrel is installed outside the inner barrel, to provide support for the inner barrel. The outer barrel serves as a water accommodating barrel, and the side wall of the inner barrel is distributed with drainage holes to make the inner barrel communicate with the outer barrel. In the process of washing clothes, clothes are placed in the inner barrel; the water levels of the two barrels are the same. However, the outer barrel is not in contact with clothes, the volume of the outer barrel of the existing washing machine is larger than that of the inner barrel. Therefore, more washing water is stored between the inner barrel and the outer barrel, and detergent between the inner barrel and the outer barrel is not sufficiently utilized, thereby not only increasing the water consumption during clothes washing, but also lowering the concentration of the detergent during washing, and leading to a large volume of the whole washing machine. In addition, after the washing machine is used for a period of time, the inner wall of the outer barrel and the outer wall of the inner barrel will be adhered with dirt, and will even go mouldy, further the washed clothes are polluted, and the barrel wall is difficult to clean. 
     Aiming at this condition, some manufacturers made improvements. To save water resources, more and more washing machines adopt a holeless inner barrel, such that the inner barrel is separated from the outer barrel, only the inner barrel is configured to store water, while the outer barrel has no water when washing clothes. Drainage holes are formed close to the upper end of the side wall of the inner barrel. In this way, when the washing machine dehydrates, water is thrown onto the inner wall of the inner barrel under the effect of a centrifugal force, and moves upwards along the inner wall of the inner barrel, and is discharged through the drainage hole on the upper end of the inner barrel, thereby improving the water-saving effect of the washing machine, and saving the using amount of detergent. 
     However, the following problem exists in the above solution: since the washing machine rotates at a high speed during dehydrating, water in clothes is directly thrown out through the drainage holes on the side wall of the inner barrel, directly hits the side wall of the outer barrel, and easily splashes all around, when water exists on the inner wall of the outer barrel for a long time, bacteria easily breed, which is not beneficial for environmental protection. 
     In addition, to increase the washing capacity of the washing machine, a greater inner barrel is required, that is, the height or diameter of the inner barrel needs to be increased. If the inner barrel has a larger size, then the outer barrel and the casing accommodating the inner barrel also need to be increased along with the increase of the inner barrel. 
     The increase of the casing of the washing machine will be limited by the space of the region at which the washing machine is placed, and the space for placing the washing machine in the house of users is limited, therefore, it is not realistic to increase the volume of the washing barrel through increasing the casing of the washing machine, then how to increase the capacity of the inner barrel under the premise of not increasing the casing of the washing machine has become a big problem for the designer. 
     The Chinese patent with the application number of CN99230455.5 discloses a single-barrel type water-saving washing machine. A water collecting device is arranged at the barrel opening of the washing barrel, the water collecting opening of the water collecting device surrounds the barrel opening of the washing barrel along the washing barrel, and the water collecting cavity, arranged on the barrel, of the water collecting device is connected with a number of drainage pipes which are arranged symmetrically from top to bottom along the outer wall of the washing barrel. During drying, the water collecting device collects centrifugal water flow due to high-speed rotation and guides downwards the centrifugal water flow to discharge. Although an outer barrel is omitted in the structure, however, when the washing machine dehydrates, since washing water firstly enters the water collecting device, the water collecting structure is an annular structure; the washing water filled inside the water collecting device is discharged downwards at different speeds, thereby destroying the balance of the washing barrel with high-speed rotation. In addition, after entering the water collecting device, the washing water is guided and converged towards the center below the washing barrel and to discharge, which is not beneficial for water discharge, such that under the effect of a centrifugal force, water concentrated in the water collecting cavity is difficult to discharge, and washing water is concentrated at the upper end of the washing barrel, thereby increasing the weight of the upper part of the washing barrel, and further destroying balance. Especially when much water remains in the washing barrel, most of the washing water is concentrated in the water collecting cavity and is not discharged, thereby making the center of gravity of the washing barrel and the outer barrel higher, generating great vibration noises, also increasing working load of a dehydrating motor, and easily damaging the motor. Finally, the water collecting device is arranged on the upper part of the washing barrel, while the washing barrel rotates during dehydrating, the radial displacement of the upper eccentricity is the maximum, to avoid collision between the water collecting device and the casing of a washing machine, a safe distance between the water collecting device and the casing must be satisfied, and the purpose of capacity expansion cannot be really achieved. 
     In view of this, the present disclosure is hereby proposed.
