Description

The refrigerator that has door-opening auxiliary

The present invention relates to a kind of refrigerator, it has: a fan is installed in the door on its heat-insulating shell; Door handle that is placed in Men Shangke around axis rotation as the double-arm lever design; A director element, it is supporting a guide rail concentric with axis, and this guide rail is meshed with a subtend guide rail that is formed on the door handle.A kind of like this refrigerator was disclosed in EP0891524B1.

On some refrigerators, especially on the sort of refrigerator with large-area door, door-opening auxiliary is installed more and more, this door-opening auxiliary can make the user feel relief when opening the door at a kind of power of closing.This power of closing for example is because the magnetic attraction of magnetic seal body produces, or owing to is present in that low pressure in the refrigerator causes.Particularly a kind of like this low pressure, it is to produce when entering air in the refrigerator being subjected to cooling off after closing the door, it may cause sizable power of closing and when firmly pulling, just might damage the stability of refrigerator.In EP0891524B1 on the disclosed refrigerator, adopt a kind of like this door handle as door-opening auxiliary, this door handle is not to be fixed on the door inflexiblely, but can link to each other with door rotatably around an axis, it is made of two lever arms from this axis, and one of them long arm is used as the handle that opens the door; Short arm is supported on the outcase of refrigerator when operating grip, thereby door is stretched out from outcase of refrigerator.

A problem of this door-opening auxiliary is: between axle and door handle certain clearance must be arranged, like this, door handle could freely turn round, and axle generally is very short, only can be achieved with very little stability so door handle centers on this rotation.This little stability can make the user that refrigerator is had the impression that lacks durability, thinks that the refrigerator quality is good inadequately, and this point must be avoided.

Therefore, for the stabilizing of gyration, used a kind of guide rail concentric with axis in EP0891524B1, this guide rail is engaged in the subtend guide rail as the reverse pilot design that is formed on the door handle.

This known guide rail is that the bending edge as a metal sheet is shaped, and it is fixed on the sidewall of refrigerator doors.The edge of above-mentioned bending is separated with refrigerator doors on side direction, and is being hidden by door handle.Like this, door handle has a bigger side direction to exceed on refrigerator doors, even stretches out above the straight line of outcase of refrigerator sidewall.This side direction exceeds that to make that following point becomes impossible: known refrigerator is placed with second the direct contacts side surfaces of refrigerator ground.

The problems referred to above are said in principle and can be solved like this, do the door of refrigerator narrower exactly; At this moment also the magnetic seal body that is placed on the door must be moved inwardly certainly, and the contact surface of magnetic seal body on the outcase of refrigerator front side must be enlarged, so that and then can realize a kind of sealing contact between magnetic seal body and the shell.This is not only required in and does structural transformation on the outcase of refrigerator, but also can lose the storage volume of outcase of refrigerator inside.

Therefore, task of the present invention provides a kind of like this refrigerator, it has a door handle that plays the door-opening auxiliary effect, according to this, the side direction of door handle on door exceeds and reduced, certainly exceed and preferably be reduced to such degree, make several such refrigerators to put side by side in contact each other, and the door handle of a refrigerator can not collided with the door or the door handle of an adjacent refrigerator.

Above-mentioned task is to solve by a kind of refrigerator with the described feature of claim 1.

Because at known refrigerator upper rail all is to stand facing each other to arrange so guide rail needs a bending, thereby a lateral distance need be arranged from the sidewall of refrigerator doors, so that guide rail can be with the subtend guide rail from the both sides interlock in the sidewall of door.And according to the present invention, guide rail has been moved to of director element and has been on the position of sidewall top of door, so the sort of bending is exactly unnecessary, and the side direction plussage of door handle on door can reduce the thickness of bending, can not lose stability, can not lose the intensity of door handle yet director element.

On the refrigerator that the present invention proposes, preferably director element is designed to simply a flat plate.Because director element is to be shaped as a flat plate, thus its manufacturing simplified widely, thereby be very worthwhile on cost.This flat plate preferably is circular segment, so advantageously makes at least one stage casing of the curved edge of this plate form guide rail.

In addition, preferably: the position that exceeds with guide rail exceeds forward according to the tangential shell from refrigerator from the sidewall of refrigerator doors.

In order to make the gyration stabilizing of door handle effectively, preferred way is: the subtend guide rail extends on a big as far as possible angle; Preferably the relative axis in the two ends of subtend guide rail constitutes an angle that is at least 120 °.Meanwhile, thus the operating physical force that is applied on the door handle guide on the door through director element more equably.

On the other hand, the angle that is constituted can not be excessive, so that the two ends of subtend guide rail are unlikely the revolution degree of freedom of damaging required door handle because of the collision to refrigerator doors excessively.According to this viewpoint, preferably: the two ends of subtend guide rail constitute one for being at most 130 ° angle on axis.
