Abstract

The utility model provides a freezing door for a freezing chamber of a refrigerator, which comprises a casing and a liner. The casing is connected with the bottom of the liner through a lower end cover; an air pressure balance body used for balancing air pressure is arranged between the liner and the casing, and a pneumatic sheet is arranged in the connection position of the air pressure balance body and the lower end cover; a gasket is arranged in the connection position of the air pressure balance body and the inner side surface of the liner, and the connection surface of the air pressure balance body and the inner side surface of the liner is horn-shaped; and the lower end cover and the air pressure balance body are connected through a guide rod arranged on the lower end cover, and the guide rod is sleeved with the pneumatic sheet. When the freezing door is applied to the refrigerator, the problem that the freezing door is inconvenient to open can be effectively solved, and the whole refrigerator can be used better and more conveniently.

Description

A kind of door of refrigerator of freezer compartment of refrigerator

Technical field

The utility model relates to a kind of deep freezer of large model, is specifically related to a kind of easily door of refrigerator of the freezer compartment of refrigerator of switch.

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.

The utility model content

The purpose of this utility model 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 utility model adopts following technical scheme:

A kind of door of refrigerator of freezer compartment of refrigerator comprises shell and inner bag, and shell and inner bag bottom is connected by bottom end cover, is provided with the air pressure balance body for equilibrium air pressure between described inner bag and 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 connected by the guide rod that is located on bottom end cover with the air pressure balance body, and described pneumatic plate is enclosed within on described guide rod.

The utility model beneficial effect: can reduce negative pressure by add an air pressure balance body in the freezer door 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, open door of refrigerator just more convenient, 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 air pressure balance body cavity body when door foaming.

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 in Fig. 1 or Fig. 2.

In 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 utility model is described in further detail 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 is connected by bottom end cover 3 with inner bag 2 bottoms, connect the air pressure balance body 4 of a bending-like between the medial surface that inner bag 2 is relative with shell 1 and 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 guide rod 4.3, on guide rod 4.3, cover has pneumatic plate 4.2, 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 4 installations of air pressure balance body are 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:, airborne moisture low due to the temperature in refrigerating chamber is condensed causes the air pressure step-down, and the ambient temperature of refrigerator is than the air pressure of high, the outside atmospheric pressure of the temperature of refrigerating chamber inside higher than refrigerating chamber, act on like this on 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, littlely will be rapidly move a section along the guide rod 4.3 of air pressure balance and move because it is light, the space that produce this moment enters to make pressure difference value to reduce and reaches the effect of normally opening door of refrigerator with regard to having extraneous air.

Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although with reference to above-described embodiment, the utility model is had been described in detail, those of ordinary skill in the field are to be understood that: still can modify or be equal to replacement the specific embodiment of the present utility model, and do not break away from any modification of the utility model spirit and scope or be equal to replacement, it all should be encompassed in the middle of claim scope of the present utility model.
