Background
In order to increase the washing capacity of the washing machine, a larger rotary tub is required, i.e., the height or diameter of the rotary tub needs to be increased. If the rotary tub has a larger size, the tub accommodating the rotary tub and the cabinet accommodating the tub also need to be increased as the rotary tub is increased. The increase of the cabinet corresponding to the appearance of the washing machine is limited by the space of the area for installing the washing machine, the position for installing the washing machine in a general user home is limited, and the purpose of increasing the capacity of the washing tub by increasing the cabinet of the washing machine is unrealistic, for example, how to increase the capacity of the rotary tub becomes a big problem which is troubled designers on the premise of not increasing the cabinet of the washing machine.
Aiming at the problem, the washing machine without an outer barrel structure is invented, water is discharged from the upper part of the inner barrel to the bottom of the outer barrel through a channel, the inner barrel cannot be completely wrapped by the outer barrel, the height of the outer barrel is low, the risk of water splashing exists in the dehydration process, the time is long, the splashed washing water is easy to corrode the shell of the box body, and the short circuit of a circuit is easy to cause.
The patent with application number CN201610210904.6 provides a hole-free inner barrel washing machine, including interior bucket and outer bucket, the bung hole department of interior bucket is equipped with the water collecting ring, the water collecting ring include the water collecting cavity and with water collecting port and the play water end of water collecting cavity intercommunication, the water collecting port orientation is interior to interior bucket, it faces to go out the water end the space between interior bucket and the outer bucket, it is connected with the drain pipe to go out the water end, the drain pipe downwardly extending reaches the bottom of outer bucket. Although the lower end of the drain pipe is inclined towards the middle part of the outer barrel, the possibility that water is splashed out of the outer barrel is reduced, the water still splashes out of the outer barrel after the inner barrel rotates at high speed, the time is long, the splashed washing water is easy to corrode the shell of the box body, and the short circuit of a circuit is easy to cause.
Patent CN201710073818.X provides an inner and outer barrel matched anti-overflow structure of a washing machine, which comprises an inner barrel and an outer barrel, wherein the inner barrel is nested in the outer barrel, an anti-overflow structure is arranged between the inner barrel and the barrel wall of the outer barrel, and the anti-overflow structure comprises a drainage piece and a matching piece; the drainage piece is arranged along the circumference of the outer wall of the inner barrel and extends towards the inner wall of the outer barrel; the fitting piece is arranged along the circumference of the inner wall of the outer barrel and extends towards the direction of the outer wall of the inner barrel; the fitting piece is arranged higher than the drainage piece, the projections of the fitting piece and the drainage piece in the vertical direction are partially overlapped, and a return channel is formed by a gap between the fitting piece and the drainage piece in the vertical direction. Although the invention adopts the matching of the concave groove and the L-shaped baffle, the residual water of the outer barrel can be prevented from splashing outside the barrel to the maximum extent. However, the drainage piece is arranged along the circumference of the outer wall of the inner barrel, so that the volume of the outer barrel is larger, the size of the inner barrel is limited while a certain space is occupied, and the capacity expansion effect is avoided; meanwhile, the anti-overflow structure can not prevent the washing water splashed under high-speed rotation from splashing on the side wall of the outer barrel to corrode the side wall of the outer barrel.
