Preferably, described rebound and described external door panel be arranged in parallel, and the thickness of described rebound is less than the thickness of described varied in thickness place thinner side foaming layer.
Preferably, the thickness of described rebound is the half of the thickness of described varied in thickness place thinner side foaming layer.
Preferably, the one side of described rebound fits with the madial wall of described external door panel.
Preferably, the thicker side of described cavity volume is the first cavity volume unit, and thinner side is the second cavity volume unit;
A described rebound part is positioned at described first cavity volume unit, and another part is positioned at described second cavity volume unit.
Preferably, the distance between the side of described rebound and the external door panel side be adjacent is 2 to 10mm.
Preferably, described rebound is cystosepiment.
Preferably, described rebound is polystyrene foam plate.
On the other hand, the utility model is by the following technical solutions:
A kind of refrigerator, described refrigerator has refrigerator door as above.
The beneficial effects of the utility model are:
The refrigerator door that the utility model provides is provided with rebound at the varied in thickness place of foaming layer, the passage of blowing agent process is formed between rebound and external door panel and/or door lining, transition is carried out at the varied in thickness place of foaming layer by rebound, foaming layer split, make varied in thickness be unlikely to too large, effective alleviation is shunk because of foaming layer the stress caused and is concentrated, eliminate courage and split hidden danger, ensure the flat appearance degree of refrigerator door, structure is reliable, long service life; In addition, place the easy and simple to handle, easy to implement of rebound, do not affect production efficiency.
The refrigerator that the utility model provides makes flat appearance degree good owing to have employed above-mentioned refrigerator door, and eliminate courage and split hidden danger, structure is reliable, long service life.

Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The utility model provides a kind of refrigerator door, comprises the external door panel and door lining that snap together, filling-foam layer in the cavity volume formed between external door panel and door lining.Door lining has step-like or other are irregularly shaped, depth of foam is uneven.The varied in thickness place of foaming layer is provided with rebound, there is the passage of blowing agent process between rebound and external door panel and/or door lining.When foaming, at the varied in thickness place of cavity volume, first blowing agent crosses rebound at the thickness smaller part of cavity volume, then enters cavity volume thickness larger part.
Carry out transition by rebound at the varied in thickness place of foaming layer, foaming layer is split, make varied in thickness be unlikely to too large, effective alleviation is shunk because of foaming layer the stress caused and is concentrated, and eliminates courage and splits hidden danger, ensure the flat appearance degree of refrigerator door, structure is reliable, long service life; In addition, place the easy and simple to handle, easy to implement of rebound, do not affect production efficiency.
Embodiment one:
Present embodiments provide a kind of refrigerator door, as shown in Figure 2, it comprises the external door panel 1 and door lining 2 that snap together.Filling-foam layer 3 in the cavity volume 5 formed between external door panel 1 and door lining 2.
Wherein, the medial surface of external door panel 1 is flat, and the medial surface of door lining 2 as shown in Figure 4, is formed with step 21 at A place and B place, thus the foaming layer 3 in cavity volume 5 can be changed at the thickness at A place and B place.The varied in thickness place of foaming layer 3 is provided with rebound 4, is split by rebound 4 pairs of foaming layers 3.In the present embodiment, rebound 4 adopts cystosepiment, and further, adopt polystyrene foam plate, itself and blowing agent have and well merge performance, also can play certain insulation effect.
As shown in Figure 1, rebound 4 and external door panel 1 are for be arrangeding in parallel, and the thickness of rebound 4 is less than the thickness of varied in thickness place thinner side foaming layer 3.In the present embodiment, rebound 4 fits with the madial wall of external door panel 1, is convenient to like this place rebound 4 before foaming.The thickness of rebound 4 is the half of the thickness of varied in thickness place thinner side foaming layer 3, makes the thickness of foaming layer 3 be stepped change, advantageously in the stress reducing varied in thickness place.
The larger side of thickness at varied in thickness place in cavity volume 5 is called the first cavity volume unit 51, the less side of thickness is called the second cavity volume unit 52, then rebound 4 has half to be positioned at the first cavity volume unit 51, half is positioned at the second cavity volume unit 52, makes foaming layer 3 carry out the change of thickness in advance when not arriving the varied in thickness place of cavity volume 5.
For convenience of the installation of rebound 4, as shown in Figure 3, between the side of rebound 4 and the side of external door panel 1 be adjacent, leave certain gap, preferably, gap is 2 to 10mm.
Wherein, rebound 4 is not limited to fits with the medial surface of external door panel 1, also can fit with the medial surface of door lining 2, or between external door panel 1 and door lining 2, as long as the effect of buffering varied in thickness can be played.
Embodiment two:
Present embodiments provide a kind of refrigerator, it has the refrigerator door as described in embodiment one.Make the flat appearance degree of refrigerator good owing to have employed above-mentioned refrigerator door, eliminate courage and split hidden danger, structure is reliable, long service life.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
