Door of refrigerator

Technical field

The present invention relates to a kind of refrigerator.The upper plate and the lower plate that particularly relate to a kind of refrigerator doors are integrally formed, can self be in sealing state, and strain take place easily and strengthen the door of refrigerator of intensity.

Background technology

Usually refrigerator is preserved food, is had a plurality of storerooms of putting food for freezing or refrigeration ground, and in order easily to pick and place food, the one side of storeroom has open architecture.

The open surface of storeroom is opened and closed by door, so that prevent to be filled in the cooling gas leakage of compartment interior.Gate open often has the plate construction identical with the storeroom front shape, so that the front openings of closed storage room.

And gate open is often by the tabular external door that has with storeroom front shape analogous shape, stick on the positive door shell body that forms outward appearance of external door, stick on external door back side when forming the door medial surface, have the door gasket that the cold air that utilizes storeroom carries out the storage basket etc. of freezing or refrigeration, and the various devices such as separate unit that are arranged on external door constitute.

Constitute the external door 300 of the door 20 of current refrigerator 10,, comprise upper plate 310, encapsulant 330, lower plate 320, assembly mouth 350 as Fig. 1 and shown in Figure 2.

External door 300 has the rectangle sheet material shape similar to the storeroom front shape, in order to strengthen the intensity by the door 20 of user's switching, makes external door 300 with metal materials such as iron usually.

By the external door 300 that metal material constitutes, the power of its intensity is by the decision of the thickness of metal, because the frequent actuating doors 20 of user, external door 300 often is subjected to the impact of accompanying with it, and therefore the external door 300 of door 20 is all used thicker metallic plate manufacturing so far.

By the external door 300 that thicker metal material forms, be difficult to press dull and stereotyped image distortion in addition, and processing is relatively more difficult.Therefore as shown in Figure 1 and Figure 2, usually external door 300 to the vertical warpage of storeroom direction, assemble with miscellaneous part.

Here, door 20 has the box shape of hollow, at the back side of external door 300 door assembly 20 liners.Therefore, on external door 300 and below, assemble independent upper plate 310 and lower plate 320.

Upper plate 310 contact with lower plate 320 on external door 300 and below front end, therefore also assemble a plurality of supports etc. in order to enlarge contact area, enlarge contacting and assemble area, assembling of lower plate 320 and external door 300.

Top and the following and upper plate 310 and the lower plate 320 of external door 300, contact area is inhomogeneous on the characteristic of its metal material, produces many places noncontact part.Therefore in order to prevent that the packing materials such as expanded material that are filled in external door 300 inside from partly flowing out by noncontact, external door 300 and on/bound fraction of lower plate 320, encapsulant 330 is set as shown in Figure 2, usually.

Encapsulant 330 usually by application or be bonded on the external door 300/lower end forms with the silica gel of the whole bound fraction of upper plate 310 and lower plate 320 or the non-setting thing of rubber or resin material, the inside/outside portion of the disengaged part of covering external door 300 and last/lower plate 320, seal.

In order to assemble equipment such as separate unit, distributor or controller, suitably opening is formed with assembly mouth 350 at most positions of external door 300.

Assembly mouth 350 after making external door 300, cuts off and cuts formation by independent operation usually.

Attractive in appearance for the door 20 that improves refrigerator 10, the common housing of the door 20 that forms by resin material in the assembling of the outside of external door 300, or at the front of external door 300 coating process etc., or outside the assembling of the front of external door 300, adorn material 40.

Recently, as at the external door 300 positive exterior materials of installing, outer dress materials 40 such as glass have been developed with gloss.Because the external door 300 of metal material and the outer dress material 40 of glass material engage mutually unevenly, therefore inhomogeneous engaging portion produces stress mutually.In order to prevent that stress from making external door 300 or adorning material 40 breakages outward, adorn outside between material 40 and external door 300 faying faces, assembling rubber-like face parts 41.

Face parts 41 and is made of rubber-like materials such as Foamexes usually, have the plate shape shape identical with outer dress material 40, be inserted between the front of the medial surface of outer dress material 40 and external door 300, closely contact with the medial surface of outer dress material 40 and closely contact, outer dress material 40 is closely contacted mutually with the positive of external door 400 with the positive of external door 300.

The door of operation current refrigerator 10 20 o'clock, the external door 300 that is inserted in door 20 inside bears the impact of door 20 when rotating, and the separate unit that is assembled in external door 300 etc. is supported.

Under the state of external door 300 and door 20 liner combinations, for the performance such as heat insulation of the door 20 of refrigerator 10, to external door 300 inner filled with foaming material.At this moment, be filled into the expanded material of external door 300 inside, be bonded in the upper plate 310 of external door 300 and encapsulant 330 sealings of lower plate 320 and door 20 liner bonding parts, be filled in external door 300 inside.

But, the external door 300 of the door 20 of current refrigerator 10, owing to form by the metal material of certain above thickness in order to have certain intensity, therefore want the intensity of reinforced door 20 and storeroom assembled portion, and because the weight of door 20 is big, the user need use bigger power actuating doors 20, and in addition, operation is also inconvenient when carrying or assembling external door 300.

In order to prevent that the expanded material that is filled in external door 300 inside from outwards flowing out, need independent encapsulant 330 be set in the bonding part of upper plate 310 and lower plate 320.Therefore need carry out the operations such as application of encapsulant 330, the problem that exists flow chart to increase, and if damage appears in encapsulant 330 or have the position that does not have application, then cause the problem that flows out expanded material.

Dress material 40 outside existing external door 300 positive sticking glass etc., and in order to cushion both and both closely to be contacted is provided with face and parts 41 between the external door 30 of the outer dress material 40 of glass material and metal material.Therefore the manufacturing expense that face parts 41 appears, and since need assembling face parts 41, the problem that flow chart increases appears.

Therefore external door 300 is formed by certain thickness metal material, can not be out of shape, and when change or mounting equipment change take place in the appearance design of the door 20 of refrigerator 10, needs redesign and makes external door 300, and its property applied flexibly is low.

For the hinged assembled part intensity of bearing big gravity and impact in each strong point of strengthening external door 300, strengthen intensity in the mode that adds assembling stiffener etc. at the partial portion of a bodily form external door 300.Thereby, need to prepare reinforcement material and assemble to have inconvenience.
