The specific embodiment
Specific embodiment below in conjunction with accompanying drawing describes door of refrigerator provided by the invention in detail.
Fig. 2 is the bottom isometric view of the one exemplary embodiment of door of refrigerator provided by the invention, and Fig. 3 is that A-A` among Fig. 2 is to profile.Part same as the prior art uses the symbol among Fig. 1 to describe.As shown in the figure, external door 40 constitutes the top of door of refrigerator 30 and the appearance of outer part, and is arranged on the bottom appearance of the chamber door liner formation chamber door 30 on external door 40 1 sides.And, between external door 40 and chamber door liner 50, possessed the thermal insulation layer 60 that liquid-solidization of filling-foam back forms.
On the inside of external door 40 outer parts, possessed several and settled floor 41.Described arrangement floor 41 forms one when external door 40 moulding, vertical with the outer part of described external door 40, and between several at intervals.
Simultaneously, the head end of described installation floor 41 cuts separated by a distance in the outer part the inside of external door 40.And, formed the resettlement groove 43 of settling the arrangement portion 71 of seal member 70 between the head end of the described arrangement floor 41 of incision and the described external door 40 peripheral the insides.
In the present embodiment, described resettlement groove 43 forms offset, but is not limited thereto.In other words, the shape of described resettlement groove 43 is so long as the shape of corresponding seal member 70, and then any structure can be used.
The peripheral the inside that is equivalent to the external door 40 of resettlement groove 43 inside has possessed fixed projection 45.Fixed projection 45, inserts among the holddown groove 73 of seal member 70 towards relative certain length of having given prominence in the inside of external door 40 outer parts.
Described fixed projection 45 is arranged on all or part of length in external door 40 outer parts the inside.And, on described fixed projection 45, have the guide surface 47 of arrangement portion 71 that guiding is placed in the seal member 70 of resettlement groove 43.Described guide surface 47 increases the width of fixed projection 45 by the lateral surface of fixed projection 45 gradually, and the direction of settling towards seal member 70 tilts to form.
And, possessed the seal member 70 of the leakage that prevents to be filled in the expanding foam solution between external door 40 and the chamber door liner 50 in chamber door 30 inside.Described seal member adopts corrugated material to form, and has and external door 40 peripheral corresponding length.Described seal member 70 is made of arrangement portion 71 that is placed in resettlement groove 43 inside and the portion of being close to 75 that is close to 50 of chamber door liners.
As mentioned above, arrangement portion 71 has the effect that seal member 70 is fixed on chamber door 30 inside in fact.The length of described arrangement portion 71 corresponding chamber doors 30, setting longer has the cross section of the formation offset corresponding with resettlement groove 43.And, formed in arrangement portion 71 in a side of arrangement portion 71 and to be placed under the state of resettlement groove 43, insert the holddown groove 73 of described fixed projection 45.
And, be close to portion 75 and extend in an end approximate vertical of resettlement groove 43, be close to chamber door liner 50 the insides, play the effect that prevents that expanding foam solution from leaking.And the front that is close to the portion of being close to 75 of chamber door liner 50 the insides has formed several jogs 77.
It is longer that described jog 77 is provided with on the length direction of being close to portion 75, and the certain spacing of being separated by.And jog 77 plays the effect of the leakage that more effectively prevents to be filled in the expanding foam solution between external door 40 and the chamber door liner 50.That is, form certain space between the inside of chamber door liner 50 and the jog 77, in this space, introduce expanding foam solution thus, therefore prevent the leakage of expanding foam solution.
Simultaneously, described chamber door liner 50 is formed by the ABS resin sheet material vacuum forming of 0.7mm.And, possessed under the state of chamber door 30 sealing storage spaces 15 in the periphery of chamber door liner 50 and to be close to above the casing 10, prevent the sealing gasket 80 that cold air flows out.For sealing gasket 80 is arranged on the chamber door liner 50, place to be provided with at chamber door liner 50 outer groove 51 be set, and on sealing gasket 80, be provided be inserted in groove 51 inside are set projection 81 is set.
Make the process of door of refrigerator provided by the invention below in conjunction with description of drawings.
Fig. 4 a to Fig. 4 c is the job state figure of the manufacturing process of the embodiment in the presentation graphs 2.
At first, shown in Fig. 4 a, under the state that external door 40 is placed in lower clamp (not having expression among the figure), in the resettlement groove 43 of external door 40, insert the arrangement portion 71 of seal member 70.At this moment, the head end of arrangement portion 71 is by guide surface 47 guiding of fixed projection 45.And, in the holddown groove 73 of arrangement portion 71, insert described fixed projection 45, prevent that thus arrangement portion is being placed in random the moving in back, resettlement groove 43 inside.
Then, shown in Fig. 4 b, on a side of external door 40, chamber door liner 50 is set.At this moment, be close to the portion of being close to 75 fronts of described seal member 70 in the inside of chamber door liner 50, and in the inside of chamber door liner 50 be close between the jog 77 of portion 75 and form certain space.But, because chamber door liner 50 has adopted the vacuum forming of ABS resin sheet material to form.Vacuum forming method can reduce the thickness of chamber door liner 50 relatively, thereby can reduce the use amount of material.
Simultaneously, upper clamp (not expression among the figure) is placed on the top of the chamber door liner 50 on being incorporated into external door 40.Then, assembling upper clamp and lower clamp prevent that external door 40 and chamber door liner 50 from moving in conjunction with the back, and between external door 40 and chamber door liner 50 filling-foam liquid.
After being filled in the expanding foam solution curing between external door 40 and the chamber door liner 50, shown in Fig. 4 c, form thermal insulation layer 60.Then, chamber door liner 50 be provided with groove 51 inner insert sealing gaskets 80 projection 81 is set, sealing gasket 80 is arranged on the described chamber door liner 50, finish the making of chamber door 30.
Scope of the present invention is not confined to the content of embodiment, and in identical technical field, knowledgeable people of the same trade can propose other variation on basis of the present invention.
