[Embodiment 1] (Outline of Embodiment 1) In this embodiment, a drawer-type freezer compartment container is installed in a freezer compartment, and even when the freezer compartment door is opened 90 degrees, the freezer compartment container can be pulled out to the outside. , In which the width of the freezer compartment is limited.

The first embodiment of the present invention will be described below with reference to the drawings. 1 is a plan sectional view of a refrigerator according to a first embodiment of the present invention, with a part thereof omitted, FIG. 2 is a longitudinal sectional view of the same, and FIG. 3 is a plan sectional view showing a state where the refrigerator is installed in a corner of a room. is there. In the figure, components other than reference numerals 18a and 19 are exactly the same as those of the conventional device, and the description thereof is omitted.
Reference numeral 18a denotes a bank tip surface of the door inner plate 18, and 19 denotes a drawer-type freezer compartment container placed on the freezer floor. As shown in the figure, the freezer compartment door 17 has no storage pocket, but the depth of the freezer compartment container 19 is increased to cover the volume of the storage pocket.

Next, the operation will be described. Freezer compartment container 1
Numeral 9 is arranged at the bottom of the freezer compartment 2, and cool air generated by the cooler 5 a is circulated by the fan 6 to cool the freezer compartment container 19. The freezer compartment container 19 is taken in and out with the freezer compartment door 17 opened. Even when the freezer compartment door 17 shown in FIG. Since the distance A (approximately 5 mm) in the freezer compartment width direction at the side end (the right end in FIG. 1) of the freezer compartment 19 exists as a space, the freezer compartment container 19 can be taken out of the freezer compartment 2 and the container 19 can be taken out. Can be easily cleaned. Since the dimension A is about 5 mm, there is no problem in putting the freezing compartment container 19 in and out even if there is some dimensional variation in manufacturing. Further, the freezer compartment container 19 has a large capacity having a size from the front end of the partition plate 7 to the front end of the freezer compartment, and can be easily and completely pulled out straight out of the refrigerator without hitting the inner plate of the door. Because it can be returned, the usability and capacity of the door pocket are fully captured. The gap between the freezer compartment container 19 and the freezer compartment wall is about 20 mm.

Referring to how the distance between the tip end portion 18a of the freezer compartment door 17 and the door outer plate line is determined, as shown in FIG. 3, the refrigerator is installed at a corner (wall) of the room as shown in FIG. When attaching, usually, a gap is provided between the wall and the side plate surface of the refrigerator in consideration of heat dissipation, but the gap is as small as about 10 to 20 mm, and the opening degree of the door at the time of installation is secured at least 90 degrees or more. When the door is opened at 90 degrees, the door outer plate line is designed to be substantially collinear with the side plate surface of the refrigerator, and the door and the freezer compartment wall have a temperature of about −18 ° C. in the freezer compartment. It has a heat insulation thickness that can be kept at an appropriate temperature, the heat insulation thickness is substantially constant, and the height of the gasket (door packing) is determined from the position of the front flange of the refrigerator box. As shown in FIG. 4, inside the gasket, a flexible fin 25a comes into contact with the outer periphery of the bank of the inner plate to prevent the gasket from falling down and form a heat insulating layer for air. At this time, for the purpose of making the number of fins plural, making the heat insulation layer of the air multilayer, and efficiently insulating heat, the position of the uppermost fin in the X-axis direction should be substantially flush with the upper surface of the gasket, The height (the bank tip surface 18a) is also determined in accordance with this.

According to this embodiment, even if the freezer compartment door 17 can be opened only by 90 degrees, the drawer-type freezer compartment container 19 can be put in and taken out without hitting the bank tip 18a of the freezer compartment door 17, and Even when a refrigerator is installed near the wall of the refrigerator, the freezer compartment container 19 can be freely taken in and out.

Embodiment 2 FIG. (Outline of Second Embodiment) In the first embodiment, the freezer compartment door is used to move the freezer compartment container in and out.
Even if the freezer compartment cannot be opened more than once, the width of the freezer compartment has been slightly reduced to make it possible.Therefore, a gap is inevitably created between the freezer compartment and the freezer compartment door. It looks bad because it can be seen. Therefore, in this embodiment, a design is improved when the freezer compartment door is opened by providing a cover at that portion.

Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a plan sectional view of a refrigerator according to a second embodiment of the present invention, in which a part of the refrigerator is omitted. In the figure, components other than reference numeral 20 are the same as those in the first embodiment, and a description thereof will be omitted. 20
Is a cover provided on the front of the gap space between the side of the freezer compartment container 19 and the wall of the freezer compartment. By providing this cover 20, when the freezer compartment door 17 is opened, the cover passes through the gap space. The inside of the freezer compartment is hidden and looks good, and the design is improved.

Embodiment 3 FIG. (Summary of Embodiment 3) This is a method for securing a circulation path of cool air when a drawer-type freezer compartment container is installed in a freezer compartment, and an air passage is provided between the freezer compartment floor surfaces of the freezer compartment containers. Also, the freezer compartment container was also provided with a ventilation hole that opened downward at the bottom. Further, the gap space existing on the side of the freezer compartment container described above is used as a return duct for cool air.

Hereinafter, a third embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a plan sectional view of a refrigerator according to a third embodiment of the present invention, in which a part of the refrigerator is omitted, FIG. 7 is a longitudinal sectional view of the refrigerator, and FIG.

According to this embodiment, the first rail protruding downward is provided at the bottom of the freezer compartment 19, and the second rail protruding upward is provided also on the floor surface of the freezer opposite thereto. By combining these with a suitable play, the positioning of the freezer compartment 19 and the guiding of the movement of the freezing and storing can be performed. The space formed between the freezer compartment container 19 and the freezer compartment floor surface is used to cool the air in the freezer compartment 2 after cooling the food or the inside of the freezer compartment container 19 to provide the ventilation holes 19a.
Is used as a return air passage for the cool air blown out from the cooling chamber 5. The space between the freezer compartment container 19 and the wall of the freezer compartment forms a part of the cool air circulation air passage. By securing the circulation path of the cool air in this way, it is possible to obtain sufficient cooling performance, to prevent the cool air from flowing into the throat portion of the door inner plate, and to prevent the gasket 25 from being dewed. it can.
