Description

Sealing latch structure for dish washer

Technical field

The invention relates to the structure of table-ware washing machine, specifically is a kind of sealing latch structure for dish washer.

Background technology

Usually,, need carry out the action of switch door repeatedly, and when closing, door need firmly be sealed in the front of dish-washing machine body in order on dish-washing machine, to deposit feeder.

For this reason, between door and body front, be provided with door sealing with bumping pin, so that door can firmly be enclosed in the body front.

Describe the door sealing of prior art in detail with bumping latch structure below in conjunction with accompanying drawing.

Fig. 1 has the door sealing dish-washing machine perspective view of bumping pin in the prior art; Fig. 2 is the vertical profile structural representation after A partly amplifies among Fig. 1.

As shown in Figure 1, bump pin 20 and be separately positioned on the front upper that inside possesses the body two side cavity 11 of sink.

As shown in Figure 2, bump pin 20 and comprise the hook portion 21 that is installed on the sidewall cavity 11 interior patchhole 11a; Be exposed to sidewall cavity 11 inboard outer, closing door at 30 o'clock, be close to the sealing 22 of door 30 sides.

And flexible in order to make hook 21 make diametric(al) in patchhole 11a, its central part has formed joint-cutting 23.

As above the assembling process that bumps pin of Gou Chenging is as follows.

To bump among the patchhole 11a that pin 20 is pressed into sidewall cavity 11, at first, will bump pin 20 aligning patchhole 11a and exert pressure, be formed with joint-cutting 23 owing to be arranged on the hook portion 21 of bumping pin 20 in the inboard of sidewall cavity 11, make hook portion 21 flexible, and be inserted into patchhole 11a inside smoothly.

Then, as above the bumping pin 20 and will link up with the inboard that a side of 21 is fixed on patchhole 11a of assembling avoids nature to come off.

Thus, closed door at 30 o'clock, door 30 combines with the front of body 10, at this moment, is assembled in the side that pin 20 sealings 22 are close to door 30 of bumping on the sidewall cavity 11, firmly fixes 30 with this.

But the existing pin that bumps that as above constitutes is when assembling, and there is the shortcoming of damaging easily in the binding site B of hook 21 and sealing 22.

When promptly bumping pin 20 and being assembled into patchhole 11a and going up, hook portion 21 is flexible, and stress focuses on the binding site b of hook portion 21 and sealing 22 thus, causes the damage of binding site b.

In other words, in order to give hook portion 21 retractilities, and joint-cutting 23 is set to the binding site of hook portion 21 and sealing 22, therefore, hook 21 is when the diametric(al) of patchhole 11a is flexible, the power that hook portion 21 applies when stretching focuses on the binding site b with turning moment, causes the damage of binding site b.

Summary of the invention

In order to solve the damage problem of hook and sealing binding site, the purpose of this invention is to provide a kind of can the raising and bump pin assembling intensity, the dish washing machine door sealing that is arranged on the body front that door is firm is with bumping latch structure.

In order to achieve the above object, sealing latch structure for dish washer of the present invention comprises that dish washer interior has possessed the body of sink, is arranged on the door that rotates previously of body, be arranged between body front and the door, when closing, improve door and body front closure bump pin; Wherein bumping pin comprises: in the hook portion that inserts in the hole and be provided with of body front one side formation, be exposed to body exterior, when door is closed, the sealing of being close to door one side, in order to make hook flexible in patchhole interior diameter direction, and the joint-cutting that forms of position in the central is characterized in that having formed on the sealing with joint-cutting and communicates, and prevents to link up with that stress focuses on the telescopic chute on the binding site between hook portion and the sealing when flexible.

As mentioned above, the present invention has improved door sealing with the structure of bumping pin, prevents to insert a position and a damage of the joint portion of being close to, position of bumping pin, thereby can prolong the life-span of bumping pin.

The specific embodiment

The present invention is described in detail below in conjunction with drawings and Examples.

The pin that bumps in the embodiment of the invention is to be assembled in inserting in the hole of forming on the body sidewall cavity equally.

As shown in the figure, the pin 200 that bumps in the embodiment of the invention comprises: be installed in the hook portion 210 on the interior patchhole 11a of sidewall cavity 11 (with reference to Fig. 2) (with reference to Fig. 2); Be exposed to sidewall cavity 11 inboard outsides, when closing door 30 (with reference to Fig. 1), be close to the sealing 220 of door 30 sides.

Here, the periphery of hook 210 is close with the diameter of patchhole 11a, and the periphery of sealing 220 is greater than the diameter of patchhole 11a.

Simultaneously, hook portion 210 is flexible for the diametric(al) at patchhole 11a, and central part has formed joint-cutting 230.

Door sealing in the present embodiment is being provided with on the sealing 220 when hook portion 210 is flexible with bumping pin 200, prevent that stress from focusing on the telescopic chute 240 on the binding site b between hook portion 210 and the sealing 220, and telescopic chute 240 communicates with joint-cutting 230.

Promptly the binding site b at hook portion 210 and sealing 220 extends the telescopic chute 240 that communicates with joint-cutting 230 that is provided with to sealing 220 1 sides.

Rectangle structure is adopted in the cross section of telescopic chute 240, and its medial surface is recessed to sealing 220 sides.

It is as follows that as above the door sealing in the embodiment of the invention of Gou Chenging bumps the assembling process of pin.

Same as the prior art, bumping among the patchhole 11a that pin is pressed into sidewall cavity 11 equally in the embodiment of the invention.

But, of the present invention bumping also is provided with telescopic chute 240 when pin 200 forms joint-cutting 230 on hook portion 210, the stress that focuses on binding site b between hook portion 210 and the sealing 220 in assembling process will be distributed to sealing 220, and therefore, it is not fragile to bump pin.

Specifically, in sidewall cavity 11 inboards, in the time of will bumping pin 200 and be pressed into patchhole 11a, telescopic chute 240 is communicated with the joint-cutting 230 that the hook portion 210 of bumping pin 200 forms, when hook portion 210 is stretched, play cushioning effect, therefore prevented the damage of binding site b between hook portion 210 and the sealing 220.

Because telescopic chute 240 is formed in the binding site b of hook portion and sealing 220, therefore, by the hook portion 210 flexible turning moments that produce, the stress that on the binding site b between hook portion 210 and the sealing 220, produces, be distributed on the sealing 220, prevented the breakage of binding site b with this.

The described pin that bumps is made by synthetic resin.
