Problems solved by technology

[0003] At present, many pulsator washing machines use the door cover structure of ordinary rotating shaft. The rotating shaft only plays the role of connecting and fixing, but has no boosting and damping functions. The door cover falls rapidly under the action of gravity, which may cause noise or even safety accidents. It is laborious, and it cannot even be opened when the power is not enough, which limits the number of users, and the versatility and practicability are not high
Some types of door cover structure will set a damper on the base connected to the rotating shaft to slow down the force when closing the door cover, but it cannot achieve the purpose of assisting when opening the door cover

Embodiment 1

[0042] In this embodiment, a method for realizing the boosting and damping functions of a door cover device is provided. The door cover device includes a door cover, a base, and a hinge connecting the door cover and the base. The hinge includes a torsion spring, and the door cover is opened from During the closing process, the hinge rotates, and the torsion spring gradually changes from a relaxed state to a tensioned state, generating an active force opposite to the closing direction of the door cover, and the active force is smaller than the gravity of the door cover itself.

[0043] In this embodiment, when the door cover is in the open state, the torsion spring is in a relaxed state. When the upper cover is closed, the torsion spring generates a tension force, and the tension force acts on the rotating device, and the rotating device generates a downward force on the door cover. A force in the opening direction. At this time, the tension force generated by the torsion spring i...

Embodiment 2

[0055] The difference between embodiment 2 and embodiment 1 is:

[0056] In this embodiment, according to the method of realizing the boosting and damping functions of the door cover device in Embodiment 1, the torsion spring in the hinge is compressed or stretched in its axial direction, so that the torsion spring is tensioned or relaxed to a certain extent, When the hinge rotates, the magnitude of the force produced by the torsion spring changes. By changing the rotation of the torsion spring in the circumferential direction and / or the expansion and contraction in the axial direction, the hinge can be stretched or tensioned to a certain extent, thereby generating an initial force. Adjusting the size of the initial force can make the door cover open and close The power assist or damping in the door changes to realize the safety and convenience of the door cover opening and closing process.

[0057] In this example, if Image 6 As shown, the door cover device with boosting a...

Embodiment 3

[0061] The difference between embodiment 3 and embodiment 1 is:

[0062] In this embodiment, one end of the torsion spring 11 is connected to the installation part 14, so that the torsion spring 11 is fixed to the rotating shaft 12; 13 is set away from the installation part 14. The positional relationship between the rotating part 13 and the rotating shaft 12 can be freely set, so that the same torsion spring 11 can have different rotation directions according to the installation method, or different installation methods can be adopted according to the torsion spring 11 with different rotation directions.

[0063] In this embodiment, the torsion spring 11, the installation part 14 and the rotating part 13 have different connection points 15 in the radial direction of the rotating shaft 12, which are used to adjust the degree of relaxation or tension of the torsion spring 11, so that the rotation of the torsion spring 11 The resulting force changes.

[0064] In this embodimen...

Abstract

The invention relates to the field of washing machines, in particular to a door cover device and a method for implementing assistance and damping functions of the door cover device. The door cover device comprises a door cover, a base and a hinge. The hinge is connected with the door cover and the base, comprises a torsional spring, a rotary shaft, a mounting portion and a rotary portion and can rotate in procedures from opening the door cover to closing the door cover, the torsional spring in relaxation states can be gradually changed to be in tension states in the procedures, and acting force which is opposite to the closing direction of the door cover can be generated and is smaller than the gravity of the door cover. The mounting portion is fixed to an end of the rotary shaft, the rotary portion can rotate around the rotary shaft, and the torsional spring sleeves the rotary shaft, is connected with an end of the rotary shaft and the rotary portion and can rotate to generate the acting force. The door cover device and the method have the advantages of simple structure, convenience in maintenance and repair and suitability for popularization and utilization.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a door cover device and method with power assist and damping functions and a washing machine Background technique [0002] The washing machine is already an indispensable household appliance in daily life, and its use is becoming more and more extensive. At present, there is a disc pulsator at the bottom of the bucket of the common pulsator washing machine, with protruding ribs on it. Driven by the pulsator, the water flow in the bucket forms a vortex that sometimes turns right and sometimes turns left, driving the fabric to rotate and tumble. , so that the dirt on the clothes can be removed. But in order to prevent foreign matter from falling into the bucket, the opening and closing door cover structure is commonly used to cover the clothing input port when using the pulsator washing machine. [0003] At present, many pulsator washing machines use the door cover struc...
