Describe in detail according to refrigerator door of the invention process below with reference to accompanying drawing.
Shown in Fig. 1-7, the refrigerator door according to the embodiment of the invention comprises: upper end cover 1a, bottom end cover 1b, door shell 2, door courage 3, thermal insulation layer 4 and gasket 5.
Particularly, upper end cover 1a and bottom end cover 1b form by the injection moulding of PP material one.
Wherein each among upper end cover 1a and the bottom end cover 1b comprises plate body 10, and the periphery of plate body 10 is along being provided with the flange 101 that extends internally, and flange 101 is along circumferentially extending first predetermined length.The inner surface of plate body 10 (i.e. the surface that is positioned at the right side as shown in Figure 6) is provided with the protruding wall 102 that extends internally, and protruding wall 102 is along circumferentially extending second predetermined length.Protruding wall 102 with flange 101 corresponding and spaced apart preset distances so that between protruding wall 102 and flange 101, limit the slot 1012 that extends along circumferentially.Protruding wall 102 is provided with a plurality of buckles 103 with flange 101 facing surfaces.
Door shell 2 has the cross section suitable with slot 1012.First end of door shell 2 is plugged in the slot (not shown) of upper end cover 1a and second end of door shell 2 is plugged in the slot 1012 of bottom end cover 1b to form drawer type door body prepackage (as shown in Figure 5).First and second ends of door shell 2 all are formed with the locating hole 21 suitable with a plurality of buckle 103.
The opening of the described drawer type door body prepackage of door courage 3 sealings is so that door courage 3 is limited with insulated space with described drawer type door body prepackage.
Thermal insulation layer 4 is filled in the described insulated space.Thermal insulation layer adopts the polyurethane foam plastics foaming to make, and this is conspicuous for the person of ordinary skill of the art, does not repeat them here.
Gasket 5 is located on the upper surface of a courage.Generally speaking, gasket 5 be contained in a courage inner surface around.
According to the refrigerator door of the embodiment of the invention, upper end cover 1a and bottom end cover 1b all adopt the PP material injection moulding that cost is relatively low and density is less to form.The present market price of PP material is 11500 yuan/ton, and its density is 0.9-0.91 gram/cubic centimetre.Than the ABS material, the price of PP material is 2/3rds of an ABS material, can reduce purchase cost thus; And the density of PP material is 9/10ths of ABS material, for the end cap made from spline structure, adopts the PP material can save consumptive material, has further reduced cost.Simultaneously, refrigerator door according to the embodiment of the invention, end cap 1a, 1b has optimized structure, is provided with a plurality of buckles 103 on protruding wall 102 and flange 101 facing surfaces, that is to say and be provided with buckle 103 in the slot 1012, and be provided with the suitable locating hole 21 of a plurality of and buckle 103 on door shell 2, can make end cap 1a when assembling, 1b has good location and position-limiting action to door shell 2, reduce the use of auxiliary material, further reduced cost.
Need illustrate at this, differentiation upper end cover 1a and bottom end cover 1b only are the needs in order to describe, in fact, the structure of upper end cover 1a and bottom end cover 1b is identical, that is to say that in the actual production, the end cap of door body is to form by a mold injection, this is understandable for the person of ordinary skill of the art.
As shown in Figure 2, according to one embodiment of present invention, plate body 10 is a general rectangular, and flange 101 and protruding wall 102 extend so that flange 101 and protruding wall 102 are U-shaped along first limit 11, second limit 12 and the 3rd limit 13 of described rectangle respectively.Thus, can make end cap 1a, 1b is shaped convenient.
Need to prove that at this described " general rectangular " is meant that at least one limit of plate body 10 can not be a straight line, for example, can be that as shown in fig. 1 second limit 12 is such, is a camber line limit.Such structure is for making product design attractive in appearance, for the person of ordinary skill of the art, is understandable.
Advantageously, according to some embodiments of the present invention, the 3rd predetermined length is extended along the 4th limit 14 of described rectangle respectively in the two ends of the two ends of flange 101 and protruding wall 102.Thus, can make end cap 1a, 1b is more tight with cooperating of door shell 2.
According to one embodiment of present invention, circumferentially spaced apart along protruding wall 102 of a plurality of buckle 103.Thus, can play better fixing and positioning action to door shell 2.
According to an example of the present invention, as shown in Figure 7, the inner face of each buckle 103 is the inclined-plane.Thus, can so that an end of door shell 2 cooperate with slot 1012.
According to one embodiment of present invention, locating hole 21 can form in punching press.Thus, can make the easy to process of door shell.
Advantageously, according to a concrete example of the present invention, as shown in Figure 4, locating hole is a rectangular opening.Thus, can make door shell 2 and end cap 1a, the assembling better effects if of 1b.
According to one embodiment of present invention, protruding wall 102 and flange 101 spaced apart 0.8mm.Thus, in assembling process, can play good sealing function, anti-leak-stopping bubble, thus reduced the use of auxiliary material in the assembling process, further reduce cost.
As shown in Figure 6, refrigerator door according to an embodiment of the invention also comprises PU sponge sealing strip 6, and an end of PU sponge sealing strip 6 links to each other with door shell 2 and the other end of PU sponge sealing strip 6 links to each other with door end cap 1b (or 1a).Thus, can make the sealing effectiveness of a body better.
Describe below according to refrigerator of the invention process.
Refrigerator according to the embodiment of the invention comprises: casing (not shown) and door body according to the above embodiment of the present invention.
Particularly, described casing is limited with a chamber.
Described door body is pivotably mounted on the described casing to seal described chamber.
Based on the door technique effect that body had according to the above embodiment of the present invention, then the refrigerator according to the embodiment of the invention also has the corresponding techniques effect.
Refrigerator door according to the embodiment of the invention, end cap 1a, 1b is by the lower PP material injection mo(u)lding of employing price, thus the reduction material cost, simultaneously by optimizing the structure of end cap, make refrigerator door in practical set, reduced the use of auxiliary material, and end cap 1a, good location and spacing effect are arranged between 1b and the metal door shell, reduce foaming back door body because of scrapping that end cap and metal door shell poor fit cause, thereby reach purpose cheaply.
In the description of this specification, concrete feature, structure, material or characteristics that the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means in conjunction with this embodiment or example description are contained at least one embodiment of the present invention or the example.In this manual, the schematic statement to above-mentioned term not necessarily refers to identical embodiment or example.And concrete feature, structure, material or the characteristics of description can be with the suitable manner combination in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present invention and aim, scope of the present invention is limited by claim and equivalent thereof.
