Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, by the following examples,
And combine accompanying drawing, dish-washing machine of the present invention and door latch structure thereof are further elaborated.Should be appreciated that
Specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of door latch structure, can apply between the inner bag of dish-washing machine and door body, it is also possible to
It is applied on other electric equipments, such as: baking box, microwave oven or disinfection cabinet etc..
Participating in shown in Fig. 1 to Fig. 3, the door latch structure of dish-washing machine of the present invention includes support 100, Button Block 200 and
Snap close 300, Button Block 200 is provided with catching groove 210, and snap close 300 is arranged on support 100, snap close 300
And being provided with flexible member 400 between support 100, flexible member 400 provides elastic force to make it to snap close 300
At least partly keep being fastened in catching groove 210.Support 100 is fixedly connected on the inner bag 500 of dish-washing machine,
Button Block 200 is fixedly connected in the door body 600 of dish-washing machine.
Concrete, see shown in Fig. 4 and Fig. 5, inner bag 500 is provided with the clasp 510 of outwardly convex,
The lower surface of frame 100 is provided with eye-splice 130, and eye-splice 130 is inserted and made support 100 and inner bag in clasp 510
500 fixing connections.Support 100 and snap close 300 are fixed by the compound mode using clasp 510 and eye-splice 130
Being connected on the inner bag 500 of dish-washing machine, installation form is simple, it is not necessary to other instruments both can complete support
100 with the installation of inner bag 500.
More specifically, support 100 is fixedly connected on the roof of internal cavity of bowl washer 500, and Button Block 200 is fixed
It is connected to the upper surface of door body 600.It is less that pull-up door body makes dish-washing machine take up room, and user operates more
Convenient.Support 100 and Button Block 200 can certainly be arranged on inner bag 500 and the side of door body 600.
Further, the left and right sides of snap close 300 is respectively arranged with rotating shaft 310, support 100 is provided with
The axis hole 110 that rotating shaft 310 is corresponding, the end of rotating shaft 310 makes the snap close 300 can in being arranged on axis hole 110
310 rotate around the shaft.Rotating shaft 310 is used to make snap close 300 be hinged on support 100 with coordinating of axis hole 110
On, around the shaft by snap close 300 310 rotate the fastening realizing snap close 300 and catching groove 210 and separate.
Seeing shown in Fig. 6 and Fig. 7, as one preferred embodiment, the lower end of snap close 300 is provided with
Downward projection of dead bolt 320, dead bolt 320 matches with catching groove 210 and makes snap close 300 lock with Button Block 200.
Dead bolt 320 has sweptback front end face 321 and the rear end face 322 turned forward, the cross section of catching groove 210
For V-arrangement.When snap close 300 is in buckling state with catching groove 210, the rear end face 322 of dead bolt 320 and button
The rear cell wall contact of groove 210, now applies horizontal pull to open door body 600, catching groove 210 to door body 600
Rear cell wall the rear end face 322 of dead bolt 320 is produced pressure, due to dead bolt 320 rear end face 322 forward
Tilt, produce component upwards when being under pressure, overcome the elastic force of flexible member 400, make dead bolt 320
Lifting and slide out from catching groove 210, door body 600 is opened.When door body 600 closed by needs, to door body
600 impose thrust, and the inward flange of door body 600 is resisted against on the front end face 321 of dead bolt 320 and produces dead bolt 320
Raw pressure, owing to the front end face 321 of dead bolt 320 tilts backwards, produces component upwards when being under pressure,
Overcome the elastic force of flexible member 400, make dead bolt 320 lift and slip in catching groove 210, door body 600 locking.
The front end face 321 of dead bolt 320 and the structure of rear end face 322 make user have only to Horizontal sliding door body 600
I.e. can complete the locking of door body 600 and open.
Further, the rear cell wall of catching groove 210 can fit with the rear end face 322 of dead bolt 320, button
The front cell wall of groove 210 can at least partly fit with the front end face 321 of dead bolt 320.Lock in door body 600
Under closed state, two end faces of dead bolt 320 fit with the cell wall of catching groove 210, make door body 600 locking more
Stable, will not produce and rock, beneficially the sealing in dish-washing machine casing.
As one preferred embodiment, the inclination angle of the front end face 321 of dead bolt 320 is less than rear end face 322
Inclination angle.This structure of dead bolt 320 makes door body 600 be easier in fastening process, is applying relatively low thrust
In the case of just can complete the locking work of door body 600, and to apply relatively when door body 600 is opened
Big pulling force, both can ensure that the sealing of dish-washing machine casing, it is also possible to avoid child to pull open dish-washing machine door body
Cause personal injury.
Preferably, the front end face 321 of dead bolt 320 and rear end face 322 intersection arc transition.In door body 600
Open with locking during, reduce the abrasion between dead bolt 320 and door body 600.
Concrete, support 100 bottom surface offers the through hole 120 corresponding with dead bolt 320, and dead bolt 320 passes
Through hole 120, the lower surface of snap close 300 is provided with protruding 330, protruding 330 near the root of dead bolt 320,
Protruding 330 edges being resisted against through hole 120.Protruding 330 effects are the positions limiting dead bolt 320, keep away
Exempt from dead bolt 320 the most on the lower, cause door body 600 resistance during locking excessive.
Concrete, flexible member 400 is torsion spring, and torsion spring set is located in rotating shaft 310, and the two ends of torsion spring are respectively
Compression is arranged on snap close 300 upper surface and support 100.The resilient force of torsion spring on snap close 300,
Snap close 300 is made to remain downward movement tendency, it is ensured that snap close 300 fastens the steady of locking with Button Block 200
Qualitative.Certainly, flexible member 400 can also use stage clip, leaf spring or gum elastic etc. other can provide
The element of elastic force.
Dish-washing machine of the present invention open and locking process as shown in Figure 6 and Figure 7:
When snap close 300 is in buckling state with catching groove 210, rear end face 322 and the catching groove 210 of dead bolt 320
The contact of rear cell wall, now door body 600 is applied horizontal pull to open door body 600, the pit of catching groove 210
Wall produces pressure to the rear end face 322 of dead bolt 320, owing to the rear end face 322 of dead bolt 320 turns forward,
Produce component upwards when being under pressure, overcome the elastic force of flexible member 400, make dead bolt 320 lift
Sliding out from catching groove 210, door body 600 is opened.
When door body 600 closed by needs, door body 600 imposing thrust, the inward flange of door body 600 is resisted against
On the front end face 321 of dead bolt 320, dead bolt 320 is produced pressure, due to dead bolt 320 front end face 321 to
Rear-inclined, produces component upwards, overcomes the elastic force of flexible member 400, make dead bolt when being under pressure
320 lift and slip in catching groove 210, door body 600 locking.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
