With the increasingly severe performance requirements of users and consumer markets on drum washing machines and drum dryers, the drum washing machines and drum dryers are developed to be high-temperature resistant, heavy-load, high-rotating-speed and high-capacity, and under the working conditions, higher requirements are also put forward on the sealing performance and the structural strength of window mats. As the volume in the drum increases, the pressure increases when the drum is fully loaded, requiring a greater sealing force for the window gasket. The existing drum washing machine and drum dryer increase the sealing force by thickening the window pad and raising the sealing surface, thus improving the water sealing performance; however, the elasticity of the window pad has a direct influence on the door closing force required by closing the door and window, so that the rebound force of the window pad on the door and window is increased, the door opening and closing force is increased, and especially for push-and-spring doors and windows with deeper installation surfaces, the door closing hand feeling is poorer, and the user experience is further influenced; meanwhile, the method needs material adding, and the production cost of the window gasket is increased. Conversely, in order to obtain better door closing hand feeling, if the window gasket is made thinner, the strength of the window gasket is reduced, so that the sealing performance of the window gasket is insufficient, and the performance problems such as water leakage and the like are easy to occur; if the user is not properly put in the laundry or operates the laundry, the cloth is repeatedly pulled during the cloth clamping operation, and thus the cloth is damaged, resulting in water leakage.

In order to solve the above problems, the present utility model provides a sealing window gasket 200 for a tub and a washing machine.

Example 1

As shown in fig. 1 to 5, the embodiment of the present utility model provides a sealing window gasket 200 for a drum, wherein the sealing window gasket 200 for a drum can be detachably connected to a drum (not shown) and disposed at an inlet of the drum, and the inlet of the drum is used for putting laundry. After the closed door 100 is closed, the gasket 200 can abut against the closed door 100, thereby sealing the cylinder. The sealing window gasket 200 for the barrel comprises a window gasket body 1 and a sealing structure 2, wherein the window gasket body 1 is detachably connected to the barrel, the window gasket body 1 comprises a supporting ring 11, the width of the supporting ring 11 extends along the axial direction of the barrel, the supporting ring 11 enables the window gasket body 1 to have certain strength, and the position of the window gasket body 1 can be ensured to be relatively fixed and not to move. The sealing structure 2 is connected to the window gasket body 1, the sealing structure 2 comprises a first sealing lip 21, one end of the first sealing lip 21 is connected to the supporting ring 11, and a transition slope 22 is arranged between the first sealing lip 21 and the supporting ring 11; the window pad body 1 and the sealing structure 2 are easy to run and clamp cloth, the transitional slope 22 increases the thickness of the joint of the window pad body 1 and the sealing structure 2, the area is reinforced to increase structural strength, when the window pad body 1 and the sealing structure 2 are clamped cloth to run due to the fact that a user is placed in the clothes or misoperations, even if the clothes can repeatedly pull the sealing window pad 200, the transitional slope 22 can avoid tearing between the window pad body 1 and the sealing structure 2, and the risk of water leakage due to the breakage of the sealing window pad 200 is reduced.
