Example one

The present embodiment discloses an opening and closing cover structure, which is applied to a washing machine, particularly to a pulsator type top opening cover washing machine, with reference to fig. 1 to 3.

The washing machine includes a casing 100 and a cover 200 hinged to the top of the casing 100, a washing inner tub 110 is provided in the casing 100, a water circulation gap is formed between the casing 100 and the inner tub 110, and a laundry input opening is formed at the top of the casing 100.

The cover 200 is opened upward, and the user puts laundry into the inner tub 110 through the laundry input port, or takes the laundry out of the inner tub 110.

The cover 200 is opened and closed downward, and the washing machine can perform washing, spin-drying, dewatering, and the like.

The opening and closing cover structure comprises a shielding sensor 300, a controller 500 and a crank and rocker assembly 400, wherein the controller 500 is respectively communicated with the shielding sensor 300 and the crank and rocker assembly 400.

The blocking sensor 300 may be a photoelectric sensor, and is disposed on the casing 100 or the cover 200 for detecting the approaching condition of the human body and feeding back the detected information to the controller 500.

One end of the crank and rocker assembly 400 is connected to the housing 100, and the other end is connected to the cover 200, and the crank and rocker assembly 400 drives the cover 200 to open or close according to the detection information of the blocking sensor 300.

That is, if the shielding sensor 300 detects that a human body approaches the washing machine and feeds information back to the controller 500, the controller 500 controls the crank and rocker assembly 400 to operate, the crank and rocker assembly 400 drives the cover 200 to open, so that the cover 200 is automatically opened, and a user can take or put clothes into operation conveniently.

If the shielding sensor 300 detects that a human body leaves the washing machine and feeds information back to the controller 500, the controller 500 controls the crank and rocker assembly 400 to act, the crank and rocker assembly 400 drives the cover body 200 to close, so that the cover body 200 is automatically closed, and the washing machine can conveniently perform washing, spin-drying, dewatering and other operations.

This washing machine switching lid structure detects the human condition of being close to through sheltering from formula sensor 300, and the motor crank rocker subassembly 400 that deuterogamies realizes the automation of washing machine lid 200 and opens and close, improves washing machine degree of automation and use convenience.

The specific installation position of the controller 500 is not limited in this embodiment, and the controller 500 may be disposed on the cover 200 or the housing 100.

In some embodiments of the present application, the shielding sensor 300 is disposed on the cover 200, so as to make full use of the space between the cover 200 and the top of the housing 100, thereby facilitating installation.

Further, the shielding sensor 300 is disposed at the top of the cover 200 and near the front edge. The arrangement is convenient to operate on one hand, and on the other hand, the arrangement is helpful for improving the accuracy of human body approach detection.

In practical application, the cover opening and closing structure in this embodiment requires the user to consciously shield the shielding sensor 300, and then the shielding sensor 300 feeds back the detected information to the controller 500, and the controller 500 controls the operation of the crank and rocker assembly 400.

The shielding sensor 300 is installed in a top-mounted manner, and a user stands on the front side of the washing machine during operation and triggers the shielding sensor 300 with hands, arms, or the like, thereby facilitating the operation.

If the blocking sensor 300 is disposed on the casing 100, for example, on the front side of the casing 100, a user or other moving object may pass through the front side of the washing machine only temporarily to trigger the cover opening and closing structure, which may result in unnecessary opening or closing of the cover 200.

In some embodiments of the present application, the blocking sensor 300 includes a first sensor 310 and a second sensor 320, and the crank and rocker assembly 400 drives the cover 200 to open or close according to the sequence of the first sensor 310 and the second sensor 320 sensed by the human body.

Specifically, when the user uses the cover opening device, the user first senses the first sensor 310 and then senses the second sensor 320, the sensing sequence is defined as a cover opening command, and the controller 500 receives the sensing sequence, controls the crank and rocker assembly 400 to move, and drives the cover 200 to open.

When the user uses the cover closing device, the user senses the second sensor 320 and then senses the first sensor 310, the sensing sequence is defined as a cover closing command, and the controller 500 receives the sensing sequence, controls the crank and rocker assembly 400 to act, and drives the cover 200 to close.

This control logic is simple and easy to implement, and improves the control reliability of opening or closing the lid body 200.

Regarding the specific structure of the crank and rocker assembly 400, in some embodiments of the present application, referring to fig. 3, the crank and rocker assembly 400 includes a motor 410 and a crank portion 420, one end of the crank portion 420 is connected to a power output end (i.e., a turning rod 411, refer to fig. 4 and 5) of the motor 410, the other end is connected to the cover 200, and the motor 410 is disposed on an inner sidewall of the housing 100.

When the motor 100 rotates in a first direction, the crank and rocker assembly 400 drives the cover 200 to open, referring to fig. 5.

When the motor 100 rotates in the second direction, the crank and rocker assembly 400 drives the cover 200 to close, as shown in fig. 4.

Further, the crank portion 420 includes a first link 421 and a second link 422 hinged to each other, one end of the first link 421 is connected to the power output end of the motor 410, and one end of the second link 422 is connected to the cover 200.

Further, a connecting support 210 is disposed on the inner wall of the cover 200, and one end of the second link 422 is rotatably connected to the connecting support 210.

Further, the crank and rocker assembly 400 is disposed at a side of the cover 200 hinged to the housing 100, specifically, a rear side of the cover 200 is hinged to a rear side of the housing 100, the cover 200 can be opened upward and rearward relative to the housing 100, the motor 410 is fixed to a rear side wall of the housing 100, and one end of the crank portion 420 (i.e., one end of the second connecting rod 422) is disposed at a position of a top plate of the cover 200 hinged to the rear side, so that the crank and rocker assembly 400 can drive the cover 200, and the cover 200 can be opened and closed conveniently.
