Description

Refrigerator with chamber door fixture

Technical field

The present invention relates to a kind of refrigerator, this refrigerator comprises a casing and at least one chamber door that surrounds out at least one insulated storage chamber.This refrigerator on chamber door, have usually one the circle around magnetic seal, under the chamber door closed condition, magnetic seal is closed storeroom as far as possible airtightly, in addition, by a magnetic force that between sealing ring and casing doorframe, acts on, make chamber door keep closed condition.Yet this magneticaction scope is very little.Therefore, can't avoid chamber door reliably is not to close fully but stay a seam, and this road is sewn on when seeing refrigerator from the outside not noticeable.

Background technology

Especially concerning the refrigerator that two or more chamber doors are arranged, such problem is very disagreeable, and described chamber door does not have to seal out separate storeroom airtightly.This storeroom can be the refrigerating chamber and the refrigerating chamber of for example combined refrigerator, perhaps also can be refrigerating chamber and so-called Di Zang chamber, and the Di Zang chamber remains on than only being cooled by the air exchange with refrigerating chamber under the high temperature of refrigerating chamber and perhaps.Promptly when a chamber door of above-mentioned refrigerator was shut, the build-up of pressure impact may cause another door to flick an almost invisible narrow slit thus, caused evaporant too much to freeze in advance thus and also therefore may cause refrigerator to lose efficacy.For avoiding above-mentioned situation occurring, need the door of refrigerator fixture.

In this case, what can infer is, as fixture a lock is set.The refrigerator with lock that can prevent fault open is known.Such lock generally comprises two parts, i.e. the protuberance of pin spare and one and this pin spare alternation, one of them parts are bearing and another parts are bearing with the casing with the door.But the shortcoming of this refrigerator is that in order to prevent accidental flicking, lock must be pinned consciously by the user.

Summary of the invention

The purpose of this invention is to provide a kind of refrigerator that has the chamber door fixture, this device has prevented that the wide seam of chamber door from opening, and does not need the user just to take part in to work.

So realize this purpose, promptly when beginning chamber door opening movement, this pin spare can overcome restoring force ground and extrude by protuberance.This allows to open chamber door by spurring door simply, wherein as long as the extrusion of pin spare is moved to be proceeded, will overcome reaction force.When closing chamber door, identical reaction force makes chamber door change buttoned-up status over to from the part opening.

Pin spare preferably have two mutually back to the inclined-plane, they and protuberance alternating action.When opening chamber door, pin spare slides back on protuberance by one of two inclined-planes earlier and removes subsequently, and the power that is applied on second inclined-plane by pin spare forces chamber door to be opened fully.When closing chamber door, situation is opposite.Therefore, the unlatching crack between a door and its frame of always having avoided the user can't see very reliably, this is because chamber door is by being pressed into closed condition or opening by interconnective inclined-plane, a pinnacle.

Suitable way is, first parts have a shell, and pin spare can be installed in the shell rotationally around one.In addition, the bearing that is used for this passes through the shell of first parts and passes through its support on the other hand to constitute on the one hand.This just makes the installation of the parts of winning very simple.

If this protuberance can constitute around the roller that a peg rotates by one, then the frictional force between these two parts is very little.

First parts preferably are bearing with the refrigerator body, and second parts are bearing with the chamber door.

According to a preferred implementation in particular for built-in refrigerator, the shell of first parts so is contained on the refrigerator body, and promptly this shell surrounds a support angle of this chamber door.

Certainly, a chamber door fixture itself can be equipped with on each chamber door of multi-door refrigerator.But a simple technical scheme is, first parts are equipped with second a pin spare that is used for a protuberance alternating action of second.

In this case, a spring just is enough to two pin spares are applied restoring force.

In addition, these two pin spares can move independently of one another, and spring applies opposite separately power to it.According to a replacement embodiment, these two pin spares firmly connect each other, and are connected with the chamber door housing by spring.
