Abstract
The invention provides a refrigeration door for a refrigerator refrigerating chamber. The refrigeration door comprises a shell and a liner, wherein the shell is connected with the bottom of the liner through a lower end cover; an air pressure balancing body used for balancing air pressure is arranged between the liner and the shell; a pneumatic piece is arranged at a joint of the air pressure balancing body and the lower end cover; a gasket is arranged at a joint of the air pressure balancing body and the inner side face of the liner; a connecting surface of the air pressure balancing body and the inner side face of the liner is in a horn shape; the lower end cover and the air pressure balancing body are connected through a guide rod which is arranged on the lower end cover; and the pneumatic piece is sleeved on the guide rod. When the refrigeration door is applied to the refrigerator, the problem that the refrigeration door is inconvenient to open can be effectively solved, so that the refrigerator is good in overall application feeling and convenient.
Description
Technical field
The present invention relates to a kind of freezing ice chamber door of large model, be specifically related to a kind of can switch the door of refrigerator of freezer compartment of refrigerator easily.
Background technology
At present, the general conventional larger refrigerator of refrigerating chamber volume, be exactly that the refrigerating chamber volume is greater than the direct cooling refrigerator of 100L specifically, and along with the negative pressure of increasing its refrigerating chamber of refrigerating chamber volume of refrigerator is increasing, thereby the suffered pressure of door of refrigerator body is also along with increasing, so just cause door of refrigerator more and more difficulty open, thereby cause bad use impression to refrigerator integral body.
Summary of the invention
The object of the invention is to solve the problem that large volume freezer compartment of refrigerator negative pressure causes greatly door of refrigerator to be difficult to open;
The present invention adopts following technical scheme:
A kind of door of refrigerator of freezer compartment of refrigerator comprises shell and inner bag, and shell links to each other by bottom end cover with the inner bag bottom, is provided with the air pressure balance body for equilibrium air pressure between described inner bag and the shell, and described air pressure balance body and bottom end cover junction are provided with pneumatic plate; Described air pressure balance body and inner side of liner face junction are provided with pad, and the joint face of described air pressure balance body and inner side of liner face is horn-like; Described bottom end cover is linked to each other by the guide rod that is located on the bottom end cover with the air pressure balance body, and described pneumatic plate is enclosed within on the described guide rod.
The invention beneficial effect: can reduce negative pressure by in the freezer door body, adding an air pressure balance body, the pneumatic plate of bottom can be realized the convenient disassembly with door of refrigerator, inside and outside air pressure balance can reduce inner suction to door of refrigerator, it is just more convenient to open door of refrigerator, laborsaving and convenient, the air pressure balance body is connected a pad with the inner bag junction, can reduce the balanced body spoilage, the balanced body top is provided with a seal cover, can stop expanding foam solution to enter in the air pressure balance body cavity body when door foaming.
Description of drawings
Fig. 1 is door of refrigerator open design schematic diagram;
Fig. 2 is the section perspective view of Fig. 1;
Fig. 3 is the blast status architecture schematic diagram of air pressure balance body among Fig. 1 or Fig. 2.
Among the figure: 1, shell, 2, inner bag, 3, bottom end cover, 4, the air pressure balance body, 4.1, the air pressure balance bar, 4.2, pneumatic plate, 4.3, guide rod 4.4, seal cover, 4.5, pad, 4.6, cosmetic sheet.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
The door of refrigerator of freezer compartment of refrigerator as depicted in figs. 1 and 2, comprise shell 1 and inner bag 2, shell 1 links to each other by bottom end cover 3 with inner bag 2 bottoms, the air pressure balance body 4 that connects a bending-like between the medial surface that inner bag 2 and shell 1 are relative and the bottom end cover 3, air pressure balance body as shown in Figure 3, air pressure balance body 4 comprises the inner air pressure balance bar 4.1 of cavity that is, the top of air pressure balance bar 4.1 is provided with seal cover 4.4, the guide rod 4.3 of an air pressure balance pneumatic plate of bottom end cover 3 bottom clampings, the lower end of air pressure balance bar 4.1 is connected on the guide rod 4.3, and cover has pneumatic plate 4.2 on the guide rod 4.3; Because inner bag 2 is thinner, be provided with one for the protection of the pad 4.5 of inner bag in air pressure balance body rod 4.1 and inner bag 2 medial surface junctions, air pressure balance bar 4.1 is horn-like with the joint face of the medial surface of inner bag 2, and outside cover has cosmetic sheet 4.6, seem also better appearance, after air pressure balance body 4 installed and fixed, use again foam filling air pressure balance body 4 peripheral spaces, can adjust the pressure difference value of freezer compartment of refrigerator and refrigerator freezing door outside by the light little motion of pneumatic plate 4.2 on the guide rod 4.3 of air pressure balance pneumatic plate, and the door of refrigerator of the refrigerator of larger freezing volume can normally be opened;
Operation principle: caused the air pressure step-down because low, the airborne moisture of temperature in the refrigerating chamber condenses, and the ambient temperature of refrigerator is higher than the air pressure of refrigerating chamber than the temperature height of refrigerating chamber inside, outside atmospheric pressure, act on like this on the pneumatic plate 4.2 outside power greater than the power (containing pneumatic plate weight) of inside, will make pneumatic plate 4.2 enter and indoorly make the external and internal pressure difference reach the level of refrigerator freezing door normal switch with this along the guide rod 4.3 of the air pressure balance pneumatic plate part air that moves upward.And when opening door of refrigerator, the power snap of refrigerator outside is in pneumatic plate 4.2, because it is light littlely will be rapidly to move a section along the guide rod 4.3 of air pressure balance and move, the space that produce this moment just has extraneous air and enters to make pressure difference value to reduce and reach the effect of normally opening door of refrigerator.
Above embodiment is only in order to illustrate that technical scheme of the present invention is not intended to limit, although with reference to above-described embodiment the present invention is had been described in detail, those of ordinary skill in the field are to be understood that: still can make amendment or be equal to replacement the specific embodiment of the present invention, and do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
