As shown in fig. 1 and 2, the present invention relates to a pushing mechanism, comprising:
a push plate 31;
a pushing part 33 slidably connected to the push plate 31; and
an elastic unit 32 provided between the push plate 31 and the pushing portion 33;
wherein, the push plate 31 is provided with a sliding chute as a sliding track of the pushing part 33, the sliding chute extends to at least one end surface of the push plate 31 and forms an opening, and the pushing part 33 extends out of the opening on the push plate 31; the two ends of the elastic unit 32 are connected to the inner wall of the chute and the pushing part 33, and the pushing part 33 has flexibility when the pushing plate 31 is driven by external force to move.
The pushing mechanism is used for pushing a door body on a household appliance, wherein the pushing part 33 is pushed against the door body, the pushing part 33 has flexibility and is provided by the elastic unit 32, specifically, when the pushing plate 31 is driven by external force to move towards the door body, the pushing part 33 is pushed against the door body, the position of the pushing part 33 is limited, so that the pushing plate 31 moves relative to the pushing part 33, and the elastic unit 32 generates deformation due to the change of the positions of the pushing plate 31 and the pushing part 33;
more specifically, because of the strong adsorption force between the door body and the box body of the household appliance, when the elastic force generated by the deformation of the elastic unit 32 is not enough to overcome the adsorption force, the relative position between the push plate 31 and the pushing portion 33 is gradually increased, so that the deformation degree of the elastic unit 32 is increased, when the elastic force accumulated by the elastic unit 32 is greater than the adsorption force, the pushing portion 33 pushes the door body open and the elastic unit 32 is recovered, and through the flexible characteristic provided by the elastic unit 32 for the pushing portion 33, the deformation degree of the elastic unit 32 is gradually increased to increase the elastic force to overcome the adsorption force for a period of time to serve as a time-delay door opening time to reserve the preparation time for a user, and meanwhile, because the pushing force is provided by the deformation of the elastic unit 32, the elastic force generated by the deformation of the elastic unit 32 is equal to or slightly greater than the adsorption force (specifically, from equal to greater than the adsorption force), the adsorption force between the door body and the box body of the household appliance can change along with the change of the use time, generally speaking, the longer the use time is, the smaller the adsorption force is, and in order to ensure the normal operation of the door opening action, the existing door opening device with fixed top thrust force often exceeds the preset adsorption force by the design of the top thrust force; compared with the fixed pushing force, the elastic force formed in the pushing mechanism can be self-adaptive to the adsorption force, so that the safety in the door opening process is improved.
In a preferred embodiment, as shown in fig. 3, a stopper 314 is disposed in the opening, and the stopper 314 limits the end position of the pushing portion 33 when the elastic unit 32 rebounds.
Furthermore, the stopper 314 is disposed at the position of the opening to block part of the opening, so that the sliding slots form a first sliding slot 311 and a second sliding slot 312;

Further, referring to fig. 4, the elastic unit 32 is shown in detail as a tension spring, which is deformed by tension to form an elastic force.
Specifically, the tension spring includes a connection end 321 and a transition section 322 at two sides, and the connection end 321 is connected to the sliding groove and the pushing portion 33;
the transition section 322 is disposed between the two connecting ends 321, and the diameters of the two connecting ends 321 in the center direction of the transition section 322 are gradually increased, so that the tension spring is olive-shaped, and specifically, the diameter d of the tension spring close to the transition section 322 is gradually increased1Diameter d of tension spring near the connecting sections 321 on both sides2Wherein the diameter of the transition section 322 is related to the diameter of the connecting section 321 by d1>d2(ii) a The transition section 322 has a larger diameter, so that the elastic deformation limit is larger, and the transition section 322 has a larger deformation degree when being pulled through the olive-shaped tension spring, and can still stably recover after deformation.
As shown in fig. 5, the pushing portion 33 includes a limiting module located in the sliding groove, a top rod 333 is installed at one end of the limiting module, the top rod 333 extends out of the pushing plate 31, the limiting module includes a first limiting rod 331 and a second limiting block 332, and the first limiting rod 331 and the second limiting block 332 are integrally formed to form an L-shaped limiting module.
The main structure of the pushing portion 33 is limited by the second sliding slot 312 in the sliding direction, the other end of the pushing portion 33 opposite to the pushing end extends outward to form a second limiting block 332, the first sliding slot 311 limits the sliding direction of the second limiting block 332, the first limiting rod 331 extends out from the opening, and the push rod 333 is disposed on the first limiting rod 331.
The stopper 314 corresponds to the second stopper 332, and when the pushing portion 33 slides relative to the pushing plate 31, the stopper 314 is located on the moving path of the second stopper 332.

the positioning block is arranged on the pushing part 33 and/or the sliding groove, the width of the positioning block is reduced from one side of the installation side to the other side, a limiting edge is formed at the terminal of the positioning block, the limiting edge abuts against the inner wall of the sliding groove and/or the side wall of the pushing part 33, and sliding friction force is reduced by reducing the contact area.
Specifically, the positioning block includes a first positioning block 313 and a second positioning block 335, the first positioning block 313 is disposed on two side walls corresponding to the second sliding slot 312 and abuts against the first limiting rod 331, the second positioning block 335 is disposed on two side surfaces corresponding to the second limiting block 332, and the second limiting block 332 abuts against an inner side wall of the first sliding slot 311, so that the sliding position of the pushing portion 33 is limited by the first positioning block 313 and the second positioning block 335, and the pushing portion 33 is prevented from moving unstably due to a gap between the pushing portion 33 and the sliding slot.
In a preferred embodiment, a boss 334 is formed by extending one end of the push rod 333 outward, the boss 334 is attached to the door body, the contact area between the push part 33 and the door body is increased, so that the pressure is reduced to protect the door body, the absorption force is large, so that the push rod 333 needs a large push force when pushing the door body, and when the contact area of the push rod 333 is small, the door body is easily damaged.
