Abstract

The invention discloses a refrigerator which is equipped with a liner for preventing the cold air leakage. The liner is installed on a whole edge on the inner surface of a door. A groove for accommodating the liner forms on the front surface of a refrigerator body. The liner which is next to the groove matches the groove mutually. The refrigerator is closed by the door in air tightness. Therefore, the cold air can be effectively prevented from leaking out from any gap between the refrigerator body and the door.

Description

Refrigerator with the liner that is used for preventing cooling gas leakage

The present invention relates to have the refrigerator of the liner that is used for preventing cooling gas leakage, have groove on especially a kind of casing,, thereby prevent that cold air from going out by the slot leakage between casing and the door so that hold the refrigerator that is installed in the liner on the door.

Be used for storing and the refrigerator of chilled food as depicted in figs. 1 and 2, casing 10, refrigerating chamber door 16a and fresh food chamber door 16b with a formation refrigerating chamber 11 and fresh-keeping food chamber 12, refrigerating chamber 11 and fresh-keeping food chamber 12 separate by a wall 15 each other, and the door of refrigerating chamber door and fresh-keeping food chamber is installed in the open side of refrigerating chamber 11 and fresh-keeping food chamber 12 respectively.Door 16 usefulness hinges are installed on the casing 10.

Liner 18 is installed on the inner surface of each.Liner 18 is made by elastomeric material, and spreads all on the whole marginal portion of inner surface of door 16.When closing to the doorstep 16, the plane 14 on the edge of liner 18 and the open front of refrigerating chamber 11 and fresh-keeping food chamber 12 contacts.Therefore, door 16 keeps refrigerating chamber 11 and fresh-keeping food chamber 12 to be closed, and lets out from refrigerating chamber 11 and fresh-keeping food chamber 12 so prevented cold air.

Yet, in the refrigerator of this prior art,, therefore there is such problem because liner 18 is contact with the plane 14 of the front side of casing 10: the possible imprecision of the contact between liner 18 and the casing 10, so also may leak out cold air.Specifically, because repeat switch door 16 when using refrigerator for a long time, the profile of liner 18 may be out of shape, and the thing followed forms the slit between plane 14 and liner 18, thereby increases the cooling gas leakage amount.When cooling gas leakage, the freezing capacity of refrigerator descends, and power consumption increases.

Proposing the present invention is in order to solve the aforementioned problems in the prior, therefore, to the object of the present invention is to provide a kind of refrigerator, and in this refrigerator, the contact between casing and the door is tight, correspondingly, reduces the leakage rate of cold air.

For achieving the above object, the invention provides a kind of refrigerator with a casing and one, wherein casing forms the refrigerating chamber of a side opening, door is used for the opening of opening/closing casing, it comprises: be installed in the liner on the inner surface, when closing to the doorstep, liner contacts with casing is airtight; Wherein, casing with part that liner contacts on be formed with groove, groove holds liner by snug fit when closing to the doorstep.

Best, liner spreads on the whole zone that contacts with casing with groove.

And, magnet can be installed in liner, so as by magnetic force door-inhale to casing.

By describing in detail below in conjunction with accompanying drawing, the present invention will be easier to understand, and its various purposes and advantage will be clearer, in the accompanying drawing:

Fig. 1 is the stereogram of refrigerator of the prior art;

Fig. 2 is the drawing in side sectional elevation of Fig. 1;

Fig. 3 is the stereogram according to refrigerator of the present invention; And

Fig. 4 is the drawing in side sectional elevation of Fig. 3.

Below, describe the present invention in detail with reference to accompanying drawing.

Fig. 3 is that Fig. 4 is the drawing in side sectional elevation of Fig. 3 according to the refrigerator stereogram when door is opened of the present invention.According to refrigerator of the present invention, similar to the refrigerator of the prior art shown in Fig. 1 and 2, have the casing, refrigerating chamber door 36a and the fresh-keeping food chamber door 36b that form refrigerating chamber 31 and fresh-keeping food chamber 32, refrigerating chamber 31 and fresh-keeping food chamber 32 separate by wall 35 each other, and refrigerating chamber door 36a and fresh-keeping food chamber door 36b are installed in the open side of refrigerating chamber 31 and fresh-keeping food chamber 32 respectively with hinge.

Casing 30 is made up of shell body and inner housing, the space that between shell body and inner housing, forms, and be filled with heat-insulating material in the door 36.About heat-insulating material, always say, available polyurethane, its effect aspect heat insulation is fairly good.In the assembling casing stage, heat-insulating material is filled in the space between shell body and the inner housing with the method for spraying foam.Be coated with a coating on the shell body, such as being coated with synthetic resin with heat treatment method, make it to have good durability, the shock proof synthetic resin of inner housing forms as styrene resin or ABS resin manufacturing.

On the inner surface of door 36, liner 38 is installed respectively.Liner 38 is made by elastomeric material, spreads all over the whole fringe region of door 36 inner surfaces.When door 36 was shut, liner 38 contacted with the front surface 34 that is connected inner housing and shell body on the edge that is positioned at the refrigerating chamber 31 and the opening of fresh-keeping food chamber 32.

On the front surface 34 of casing 30, form the groove 40 that holds liner 38.When each 36 when shutting, be embedded in the groove 40 to liner 38 snug fit, like this, when closing to the doorstep 36, refrigerating chamber 31 and fresh-keeping food chamber 32 are by in the hermetic seal.Because liner 38 installs by being embedded in the groove 40, refrigerating chamber 31 and 32 hermetic seal degree are better than refrigerator of the prior art, and, although owing to use for a long time, the shape deformation of liner, the hermetic seal effect can not weaken.Therefore, prevented that effectively cold air from leaking out from refrigerating chamber 31 and fresh-keeping food chamber 32, so, the phenomenon that refrigerating efficiency reduces and power consumption increases can not appear.

In liner 38, magnet 50 spreads on the whole zone of liner 38.Because the magnetic force of magnet, liner 38 keeps more firmly contacting closely with the side inner surface with the basal surface of groove 40, therefore, more effectively prevents cooling gas leakage.

Moreover, according to the present invention, since the existence of groove 40, the space of having reduced filling heat insulator, thus its attached effect is the demand that has reduced heat-insulating material.

Illustrated and it will be appreciated that the present invention that diagram and embodiment only are for illustrative purposes, are not to be used for limiting the present invention although described in detail, aim of the present invention and scope are only limited by accompanying Claim.
