Abstract

The utility model relates to a combined refrigerator door. The inner of the existing refrigerator major door is provided with a containing chamber whose rear side wall is provided with a plurality of through holes and an interlayer inside for placing an elastic body and a movable plate; the movable plate is provided with a plurality of through holes respectively corresponding to the through holes of the rear side wall. One side of the rear side wall of the containing chamber is provided with through holes corresponding to two actuating rods and communicated with the interlayer. The major door is provided with a minor door; the major door outside the side wall of the containing chamber is provided with two actuating rods respectively provided with a tension spring; one end of each spring is fixed to the end of respective actuating rod, and the other end is fixed to the major door. Meanwhile, the tail end of each actuating rod is connected with a starting rope which can control the displacement of the movable plate according to the opening condition of the minor door, prevent cold air in a refrigerating chamber running off and reach the goal of energy saving.

Description

Refrigerator door

The utility model relates to a kind of refrigerator doors.

Which kind of mode refrigeration no matter refrigerator adopt, its casing all need adopt the good material of heat-insulating property to make, and be furnished with the good cold sotrage door of heat-insulating property, to keep the low temperature in the refrigerator, reach the purpose of chilled food, but when access food, because the frequent refrigerator doors of opening tends to make a large amount of cold airs and refrigerator hot-air on every side to carry out heat exchange, thereby internal temperature of refrigerator is risen, for reducing the temperature of refrigerator inside, then need expend lot of energy again.

The purpose of this utility model is to design a kind of novel refrigerator doors, makes people when frequent access food, reduces the loss of cold air as far as possible, thereby reaches the purpose of conserve energy.

The purpose of this utility model is achieved in that a kind of primary-secondary type refrigerator doors, it establishes a room at the female Men Nei of refrigerator, and the rear wall of room is provided with many perforations, offers a groove and longitudinal extension in the rear wall upper end, form the rear wall interlayer, in order to lay elastomer and portable plate; Portable plate is provided with many perforations, its perforation and rear wall perforation corresponding one by one, sheathed two actuating rods on female door in the chamber sidewall outside, extension spring is housed on the actuating rod, spring one end is fixed on female door, the other end is fixed in the actuating rod end, and room rear wall side is corresponding with two actuating rods to be provided with two perforation, and perforation communicates with the rear wall interlayer.The actuating rod tail end is connected with a priming rope, and the perforation that this rope is set in the room rear wall is connected with portable plate with elastomer.

Advantage of the present utility model is: people are when using cold compartment of refrigerator, the article of need long-term storage can be placed refrigerating chamber, and the food of frequent access is put in female the room that upward is provided with, like this, this part food of access need not to open female door, reduce cold air and run off, simultaneously, open cervical orifice of uterus and be, under the control of actuating rod, can seal the perforation of room rear wall, make room and refrigerating chamber isolated, prevent that temperature of refrigerating chamber from rising.

Figure one is room big and small door and the interlinked mechanism top plan view that places on female door;

Figure two is A-A face cutaway views among the figure one;

Figure three is room rear wall cutaway views;

Figure four, figure five are respectively the cervical orifice of uterus of the different opening directions that are provided with on female door.

Below in conjunction with accompanying drawing the utility model embodiment is further described.

By figure one to figure three as seen, the utility model is in female door (1) inboard of refrigerator one room (2) to be set, room rear wall (3) is provided with many perforations (31), offer a groove and longitudinal extension formation interlayer (32) in room rear wall (3) upper end, put crooked reed (4) and portable plate (5) in the interlayer (32), portable plate (5) is gone up the corresponding many perforations (51) that are provided with rear wall (3), two perforation (33) are set in that room rear wall (3) is corresponding with actuating rod (6) homonymy, this perforation (33) communicates with interlayer (32), the corresponding perforation of crooked reed (4) (33) locates to be provided with vertical slotted hole (41), on female door (1), established cervical orifice of uterus (8), on female door (1), be provided with two actuating rods (6) near room (2) the one sidewalls outside, actuating rod (6) is gone up suit one extension spring (7), these extension spring (7) one ends are fixed on female door (1), the other end is fixed on actuating rod (6) end, actuating rod (6) end is connected with a priming rope (61) simultaneously, the priming rope other end passes the perforation (33) on the rear wall of room (2), elongated hole (41) on the crooked reed (4), be connected with portable plate (5) at last, for actuating rod (6) can be moved with the switching of cervical orifice of uterus, turning round side at the pivot of cervical orifice of uterus (8) is an arc section (81), simultaneously be provided with magnet (82) and caulking gum in the periphery inboard of cervical orifice of uterus (8), be beneficial to cervical orifice of uterus (8) when closed with closely closing of female door (1).

The course of work of the present utility model is: cervical orifice of uterus (8) is when closing, under the effect of magnet (82) and caulking gum, with closely closing of female door (1), actuating rod (6) is subjected to pushing of cervical orifice of uterus (8) arc section (81), make extension spring (7) be extended state, at this moment, priming rope (61) between actuating rod (6) and portable plate (5) slightly is lax, under the elastic force effect of crooked reed (4), make portable plate (5) place the opposite side of the interlayer (32) of rear wall (3), perforation (51) on portable plate this moment (5) is overlapped with the perforation (31) on the rear wall (3), cold air in the cold compartment of refrigerator is by perforation (31), (51) enter room (2), implement stored refrigerated the food in the room (2); When opening cervical orifice of uterus (8), under the effect of the return action power of extension spring (7), actuating rod (6) is closely against on the arc section (81) of cervical orifice of uterus (8), and by the terminal priming rope (61) of actuating rod (6), affect the portable plate (5) of priming rope (61) other end, make it overcome the elastic force of crooked reed (4) and produce displacement, thereby make perforation (31) mutual dislocation on perforation (51) and room (2) rear wall (3) on the portable plate (5), cut off the cold air path of cold compartment of refrigerator and room (2), prevent that a large amount of cold airs run off in the refrigerating chamber.

Figure four, figure five are for being provided with the embodiment schematic diagram of the cervical orifice of uterus (8) of different opening directions on female door (1).
