detailed description

In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

Example 1

As shown in Fig. 1 and Fig. 2, a drum washing machine is provided in this embodiment, the drum washing machine includes a housing 1 and an observation door 2, the observation door 2 is connected with the front plate 3 of the housing 1 through a rotating lifting mechanism, and the observation door 2 It can be opened and closed upwards/downwards by rotating the telescopic mechanism.

Wherein the rotating lifting mechanism includes a telescopic rod 4 arranged on the front plate 3 for opening and lifting/pull-down of the observation door 2, one end of the telescopic rod 4 is hinged with the side wall of the observation door 2, and the other end is hinged with the front plate 3. The telescopic rod 4 is a telescopic cylinder, which is hinged to one end of the front plate 3 so that the telescopic cylinder can rotate within a predetermined angle.

In the drum washing machine provided in this embodiment, when the telescopic rod 4 is a telescopic cylinder, the observation door 2 can be lifted or lowered to turn over a certain angle according to the needs of the user, and the position will not change at this angle position. The structure can facilitate the user to open the drum washing machine when the space is relatively narrow, and the telescopic cylinder can prevent the problem that the observation door 2 is closed after the observation door 2 is opened by its own gravity.

The rotating lifting mechanism also includes a guide rod 5, one end of which is hinged to the side wall of the observation door 2, and the other end is hinged to the front plate 3. The purpose of setting the guide rod 5 is to make the observation door 2 open and close smoothly when it is lifted up or pulled down, and at the same time prevent the occurrence of positional deviation between the observation door 2 and the casing 1 when it returns to the original position, resulting in the problem of poor sealing and water leakage. .

In order to prevent the observation door 2 from automatically returning to the initial position after opening, the drum washing machine in this embodiment also includes a limit mechanism for limiting the specific position of the end of the guide rod 5 close to the front plate 3, wherein the limit mechanism can be arranged on the front plate 3 or on the guide rod 5.

One end of the guide bar 5 near the front plate 3 can be fixed or slidable relative to the front plate 3. When the end of the guide bar 5 near the front plate 3 is slidable relative to the front plate 3, the front plate 3 is provided with a guide groove 6, and the guide bar 5. A guide block 7 is provided at one end close to the front plate 3, and the guide block 7 is set in the guide groove 6 and can slide back and forth along the height direction of the guide groove 6 to drive the guide rod 5 to slide.

Wherein, the above-mentioned limiting mechanism includes not less than one limiting slot 8 arranged on the front plate 3, and a limiting block 9 arranged on the end of the guide block 7 away from the guide rod 5, as shown in Figures 3 and 4, the limiting The positioning block 9 is matched with the limiting groove 8, and the limiting groove 8 is used to limit the limiting block 9 in the limiting groove 8, so as to prevent the limiting block 9 from sliding up and down when the observation door 2 is fixed somewhere to drive the guide rod 5 slides up and down; the limit groove 8 is arranged along the height direction of the guide groove 6, and the limit groove 8 communicates with the guide groove 6 so that the limit groove 8 and the limit block 9 realize the position-limiting effect. Wherein, the height of the limiting groove 8 is greater than the height of the limiting block 9, and the width of the limiting groove 8 is greater than the width of the limiting block 9, so as to ensure that the limiting block 9 can enter the limiting groove 8.
