Embodiment 1

[0033] Such as Figure 1 to Figure 6 As shown, a washing machine equipped with an upper cover closing buffer device includes: a control panel base 2 and an upper cover 1 connected to the control panel base 2 . An upper cover closing buffer device is arranged between the upper cover 1 and the control panel base 2 , and the upper cover closing buffer device is mainly composed of a crank linkage mechanism composed of an air / hydraulic buffer cylinder 4 and a crank 3 . The air / hydraulic buffer cylinder 4 includes a pressure cylinder 42 and a piston rod 41 movably arranged in the pressure cylinder 42. The fixed end 43 of the pressure cylinder 42 is movably connected with the washing machine control panel base 2. The piston The movable end 44 of the rod 41 is rotatably connected with the crank 3 which is fixedly connected with the rotating shaft 11 .

[0034]In this embodiment, the air / hydraulic buffer cylinder 4 can be configured as a buffer cylinder, or as a hydraulic buffer cylin...

Embodiment 2

[0047] Such as Figure 1 to Figure 5 Shown, a kind of washing machine that the loam cake closing buffer device as described in embodiment 1 is housed. One end of the rotating shaft 11 of the upper cover 1 is provided with the above-mentioned upper cover closing buffer device mainly composed of the air / hydraulic buffer cylinder 4 and the crank 3 . The air / hydraulic buffer cylinder 4 and the crank 3 are installed on the control panel base 2 through the fixed frame 5 .

[0048] In this embodiment, the air / hydraulic buffer cylinder 4 can also be arranged at one or more places along the axis of the rotating shaft 11 . Preferably, air / hydraulic buffer cylinders 4 are respectively provided at both ends of the rotating shaft 11 . Therefore, the upper cover can be closed more smoothly, preventing lateral movement and instability.

[0049] In this embodiment, the upper cover 1 can be set to be pivotally connected to the control panel base 2 only through the rotating shaft 11; it can ...

Abstract

The invention relates to a washing machine provided with an upper cover closing buffering device. The washing machine comprises a control plate seat and an upper cover connected with the control plate seat. The upper cover closing buffering device is arranged between the upper cover and the control plate seat, and the upper cover closing buffering device is mainly composed of an atmospheric / hydraulic pressure buffering cylinder and a crank-link mechanism composed of a crank. The atmospheric / hydraulic pressure buffering cylinder comprises a pressure cylinder and a piston rod movably arranged in the pressure cylinder. The pressure cylinder and the control plate seat form a rotating pair, and the piston rod and the crank form a rotating pair. When the upper cover is closed, the piston rod moves towards the bottom of the pressure cylinder along the axis. The moving speed of the piston rod becomes lower under the action of atmospheric pressure or hydraulic pressure inside the pressure cylinder, the upper cover can slowly close, and the purpose of avoiding collision is achieved.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine equipped with an upper cover closing buffer device. Background technique [0002] In the existing washing machine, the cover and the upper frame of the casing are hinged normally, so the opening and closing of the cover has no buffer force, especially in the process of closing the cover, if you let go of your hand halfway, the cover will follow the gravity and inertial force. Under the action, it quickly closes down and collides with the upper frame, making noise and even causing damage. For this reason, many existing patents have proposed solutions to the above-mentioned problems. [0003] For example, the cover structure of the washing machine disclosed in the Chinese patent application number CN1884672 and its manufacturing method, the cover structure of the washing machine includes: a cover main body; a buffer member surrounding the peripheral portion of the above-menti...
