[0018] The application will be further described below with reference to the accompanying drawings.
[0019] The household appliance, such as a washing machine, comprises a box body 1, an outer barrel 2 mounted in the box body 1, and a door assembly 3 mounted with the box body 1, and the water leakage prevention structure comprises an outer barrel front cover 4 integrally formed with the outer barrel 2. The outer barrel front cover 4 comprises an outer barrel front cover lower part 40 and an outer barrel front cover upper part 41 connected with each other, and the outer barrel front cover upper part 41 is hollow.
[0020] The outer barrel door flap hinge 5 is arranged at the upper end of the outer barrel front cover lower part 40, and the outer barrel door flap 6 is hinged with the outer barrel door flap hinge 5, so that the outer barrel door flap 6 can rotate relative to the outer barrel front cover lower part 40.
[0021] The outer tub door flap lock catch 7 is installed on the clamping column 42, and can rotate along the clamping column 42 after being pressed on the clamping column 42. The outer tub door flap lock catch 7 comprises a long arm 70 and a short arm 71. When the outer tub door flap lock catch 7 is rotated, the long arm 70 is located on the outer side surface of the outer tub door flap 6, so that the outer tub door flap 6 cannot be turned outward. When the long arm 70 is located on the outer side surface of the outer tub door flap lower portion 40, the outer tub door flap 6 can be turned outward.
[0022] The push-pull handle 8 is integrally formed on the outer tub door flap 6 above the outer tub door flap hinge 5. The outer tub door flap 6 is formed with a plurality of spaced clamping buckles 60 at the circumferential end. The outer tub door flap upper portion 41 is formed with a clamping hook 410 corresponding to the clamping buckles 60 at the position opposite to the clamping buckles 60, so as to fix the outer tub door flap 6 and the outer tub door flap upper portion 41 together. In order to enhance the sealing effect between the outer tub door flap 6 and the outer tub door flap 4, the outer tub door flap sealing strip 9 is installed between the outer tub door flap 6 and the outer tub door flap 4. The outer tub door flap sealing strip 9 is assembled in the clamping groove 61 formed on the outer tub door flap 6, so as to prevent water leakage caused by water vapor leakage.
[0023] The present application is suitable for the anti-leakage structure of the outer tub of household appliances. When clothes need to be washed, the door assembly is opened, the upper arm 70 of the outer tub door flap lock catch 7 is placed on the outer side surface of the outer tub door flap lower portion 40, the outer tub door flap 6 is loosened, and the outer tub door flap 6 is pulled out by the push-pull handle 8. The clothes are taken out and the above-mentioned operation is repeated. The present application is suitable for the anti-leakage structure of the outer tub of household appliances, is convenient and safe to install, is simple to operate, provides better user experience, and avoids the risk of water leakage.
[0024] The above-mentioned is only the preferred embodiment of the present application. It should be pointed out that those skilled in the art can make several improvements without departing from the principle of the present application, and these improvements should be regarded as the protection scope of the present application.
