Abstract

To provide a door of a refrigerator in which a thermal insulating effect can be improved. A door is constituted by a door front plate 6 having the right and left sides 5 folded from each other, a gasket fixing sash 21 extrusion molded having a stepped part 20 inserted into the right and left sides 5 of the door front plate 6, a handle of injection molded having upper and lower sides 8 of the door front plate 6 inserted therein and a cap 10.

Description

Refrigerator doors

The present invention relates to the structure of refrigerator doors.

Recently, the main flow of refrigerator doors structure is from the rotary drawer type that develops into.

As traditional this kind refrigerator doors, for example Japan Patent is real opens shown in the clear 62-68217 communique.

Following with reference to aftermentioned Fig. 4-5, the reality of above-mentioned conventional art is opened clear 62-68217 communique content describe.Among the figure, 1 is refrigerator body, in its front openings portion refrigerating-chamber door 2 is set respectively, drawer type refrigerating chamber door 3 and drawer type vegetable compartment door 4 (hereinafter referred to as door).

The liner of the extrusion molding in the limit, the left and right sides 5 of door 3 door face boards 6 by 5 bendings of limit, the left and right sides, insertion door face board 6 is installed with the handle 9 and the lid 10 of going up the synthetic resin injection moulding in the bottom 8 of frame 7, insertion door face board 6 and is formed frame structure.

On framework, the liner that is fixed on extrusion molding are installed with the flange 11 of frame 7, keep pulling out between the reinforcement plate 12 used with guide rail and the door inner panel 13 and inject foamed thermal insulating 14, liner 16 is embedded in the liner mounting groove 15 that is made of with the handle 9 and the lid 10 of frame 7, injection moulding the liner installation of extrusion molding.

In addition, keep pulling out pulling out with guide rail 17 on the reinforcement plate of using with guide rail 12 and constitute door 3 from being fixed on, door 3 contacts with refrigerator body 1 across liner 16.

Yet, if according to above-mentioned conventional construction, keeping pulling out reinforcement plate of using with guide rail 12 and the liner that door inner panel 13 is fixed on extrusion molding installs on the same one side of the flange 11 of using frame 7, in order to prevent that foamed thermal insulating 14 from spilling, must seal with polyester form 18, and because there is the shortcoming of insulation effect deterioration in door inner panel 13 and keep pulling out the reinforcement plate of using with guide rail 12 and contact.

Therefore, the object of the invention is to provide the door of refrigerator that can overcome above-mentioned conventional art shortcoming.

For reaching this purpose, the present invention is provided with end difference on the flange of the liner installation doorframe of extrusion molding, be fixed on this end difference keeping pulling out the reinforcement plate of using with guide rail.

The present invention is owing to make end difference with the liner installation of extrusion molding with the flange of frame, and will pull out with guide rail and remain on this end difference, thereby do not need to use encapsulants such as polyester form, can save Master Cost, because of the abundant filling foamed thermal insulating of energy, insulation effect is improved simultaneously.

Simple declaration to accompanying drawing.

Fig. 1 is the profile of expression one embodiment of the invention refrigerator doors,

Fig. 2 is the partial longitudinal section of expression one embodiment of the invention refrigerator doors,

Fig. 3 is the main body figure of expression one embodiment of the invention refrigerator doors,

Fig. 4 is the C-C profile of the refrigerator shown in Figure 5 of expression conventional case,

Fig. 5 is the stereogram of expression conventional case refrigerator.

Below, with reference to Fig. 1-3, one embodiment of the invention is described.For putting on behind the same numeral no longer to its detailed description, only different piece is narrated with the part of conventional case same configuration.

Among the figure, the liner that is provided with the extrusion molding of end difference 20 on door 26 door face boards 6, the flange 19 in it inserts the limit, the left and right sides 5 of door face board 6 by left and right sides spring song install with frame 21 and allow door face board 6 on the handle 9 of synthetic resin injection mouldings of bottom's 8 insertions and the frame structure that lid 10 is formed.

Install at this framework, the liner that is fixed on extrusion molding and to pull out the reinforcement plate 22 used with guide rail with the maintenance on the flange end difference 20 of frame 21, install with injecting foamed thermal insulating 14 between 19 contacted inner panels of flange 23 of frame 21, in the liner mounting groove 15 that liner 16 embeddings are made of with the handle 9 and the lid 10 of frame 21, injection moulding the liner installation of extrusion molding with the liner of extrusion molding.

In addition, keep pulling out pulling out on the reinforcement plate of using with guide rail 22 with being fixed on guide rail 17 formation doors 26.

In above-mentioned structure, owing to be installed on the end difference 20 of liner installation with the flange 19 of frame 21 of extrusion molding with keeping pulling out the reinforcement plate of using with guide rail 22, make the installed surface 24 of an inner panel 23 and keep pulling out top 25 of the reinforcement plate 22 used with guide rail and be in same plane, foamed thermal insulating 14 can not leak, encapsulants such as polyester form need not be used, thereby Master Cost can be cut down.

In addition, can improve insulation effect at the situation retrofilling foamed thermal insulating 14 that keeps pulling out reinforcement plate 22 discord door inner panels 23 contacts of using with guide rail.

In sum, the present invention is owing to be installed on the end difference of liner installation with the frame flange of extrusion molding keeping pulling out the reinforcement plate of using with guide rail, make the installed surface of an inner panel and keep pulling out the reinforcement plate used with guide rail above be in same plane, foamed thermal insulating can not leak, need not use encapsulants such as polyester form, can cut down Master Cost, simultaneously owing to constructing thereby can provide a kind of refrigerator doors that improves insulation effect at a situation retrofilling foamed thermal insulating that keeps pulling out the reinforcement plate discord door inner panel contact of using with guide rail.

Claims

1. refrigerator doors, door face board, the foamed thermal insulating that is bent by limit, the left and right sides, allow the liner of extrusion molding on handle that the following synthetic resin that inserts of going up of door face board makes and lid, limit, the insertion above-mentioned door face board left and right sides install, keep pulling out a reinforcement plate and the inner panel used with guide rail and form with frame, it is characterized in that, the part of above-mentioned frame is made step portion, reinforcement plate is fixed on this end difference.
