Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a refrigerator having compartments formed within a curved storage chamber.

(b) Prior Art Conventional refrigerators of this type have compartments that are cooled to various temperatures to accommodate the diversification of stored foods. Some methods of cooling the compartments directly introduce cold air, while others indirectly cool the interior through the walls of the compartments in order to prevent the stored food from drying out. An example of such an indirect cooling method is Japanese Utility Model Publication No. 54-31390.

(c) Problems to be solved by the invention In such a conventional structure, the container constitutes a compartment (low-temperature container), and a cold air passage is formed between it and the partition plate at the rear of the compartment frame, so the internal volume is inevitably limited. It gets narrower.

There is also a drawback h'--that the space behind one section frame becomes a dead space.

B.) Means for Solving the Problems The present invention solves the problems by providing a front member at the edge of the opening of the storage chamber. The plate (8) and the case α attached to the upper plate (501 and opened forward and downward) constitute a compartment α2, and the lower surface of the upper plate 5 is connected to the cold air passage outside the case Q1. Forms a cold air passage (G), and in addition, case α■
The portion of the upper plate 60) inward from the lower end is recessed.

(E) Function According to the present invention, since the upper plate of the partition plate constituting the lower wall of the partition is recessed, the internal volume of the partition is expanded and the dead space behind the front member is effectively utilized. Furthermore, due to the sloped shape around the top plate, the cold air from the outside of the case is transferred to the bottom of the top plate.
It becomes easier to flow into the 1st route.

(F) Embodiment An embodiment will be explained with reference to the drawings. FIG. 6 shows a refrigerator (1) as an example. (2) is a heat insulating box body that opens at the front, and (3) is a heat insulating partition wall that partitions the inside of the refrigerator, with a freezer compartment (4) formed above it. (5) is located in the lower part of the refrigerator, and below it is a vegetable compartment (6) consisting of a container (6).

The space inside the refrigerator is further divided into upper and lower sections by a heat-insulating partition plate (8), and the lower part thereof is used as a refrigerating room (9) which is cooled to a refrigerating temperature of +3°C or the like. Partition board (8) and partition wall (3)
An ice greenhouse α2 as a compartment is formed between the compartment plate (8), the compartment plate (8), and a transparent inner door circle.

A cooling chamber 03) is formed within the partition wall (3), and a cooler (14) included in the refrigeration cycle is housed here. A duct α51 (161) is formed at the rear of the cooling chamber 09 and extends vertically in communication with the cooling chamber 09, and a blower (17) is also provided.The blower 0D is operated to supply cold air from the cooler 04) to the duct 05). Q6) Direction, duct 09
The liquid is then discharged into the freezer compartment (4). Duct (A) is case α
Cold air is discharged from the discharge port 08) opened in the back wall of the rear insulation box body (2), and the opening and closing of this discharge port U is controlled by a damper thermo H that senses the temperature inside the refrigerator compartment (9). .

The partition plate (8) is located behind the front panel provided on the left and right sides of the lower opening edge of the partition wall (3). Also, (21)
(23' (c) and 124) are respectively in the freezer compartment (4)
This is an insulating door that freely opens and closes the openings of the front of the ice greenhouse aω, the refrigerator compartment (9), and the vegetable compartment (7).

FIG. 1 shows an enlarged side sectional view of the ice chamber α2 portion, and FIG. 2 shows a front sectional view thereof. Furthermore, FIG. 3 shows an exploded perspective view of the ice chamber α2. Inside is a damper thermo cover, which has a heat insulating material inside and is located between the case αα and the back wall of the insulation box body (2), and directs the cold air flowing out from the outlet αυ into the refrigerator compartment (9). It has a side discharge port (2) that allows the cold air to flow down, and a discharge hole that discharges the cold air forward. Case(
On the rear upper surface of 101, there is a groove (5) that spans the entire width of the case.
is formed, and a molded heat insulating material container that is open to the top and to the left and right and constitutes a cold air passage (2) for distribution extending from side to side is housed in this groove (2). As shown in Fig. 2, the left and right side surfaces of the case (11) are spaced apart from both sides of the inner surface of the insulating box (2) to form a cold air passage (
It constitutes a cold air passageway (7) that communicates with the cold air passage (7). At this time, the opening edge and back surface of the case (II) are in contact with the lower surface of the partition wall (3) and the inner surface of the insulation box (2) on both sides.The upper surface of case 0I has a small gap between the partition walls (3). , also has a projection Cυ projecting upward in the central part.An operating arm C32 is rotatably fixed to this projection 31), and a damper plate is inserted into the long hole (C) formed at the rear end of this arm 02. (b) is rotatably engaged. The damper plate (b) is a damper thermo cover 1 formed integrally with an opening/closing plate (40) located at the innermost part and a closing plate 0υ located in front of it.
The discharge port 0 of 25) opens at the center of the cold air passage (to), and the opening/closing plate (4G) is exposed at a position immediately before the discharge ports 6 to 8 in the cold air passage (to). By operating this knob (42 left and right), the cold air passage +
28) The amount of cold air flowing inside can be adjusted. Also, on the front side edge of the groove [27] there is a lip (4) that protrudes upward.

is formed, and a notch (29) is formed in the insulation material 4 correspondingly.
A) is formed. The closing plate 0υ is located just in front of this notch (44).

This closing plate (41) always closes the notch (44) even if the arm C32 moves left and right. This blocking plate (4υ and lip (43) prevents the cold air from flowing into the upper surface of the case αα, so the cold air stays here and the case 00)
This prevents the inconvenience of frost forming on the top surface. This is a molded heat insulator (a cover that closes the top opening).

Figures 4 and 5 show enlarged views of the side and front parts of the partition plate (8), respectively. (46) and (47) are the outer box and inner box that make up the insulation box (2).
(This is the insulation material filled between the partition plates (8) and the upper plate (50+, lower plate 1) with the inner side depressed from the edge.
511 and the drawing board (50151), the insulating material 6z is made of a hollow insulating material 6z and is provided along the upper surface of the lower board 6D, In addition, the lower plate 511 has a plurality of through holes (531) closer to the center than the edge, and the heat insulating material C2+ also has through holes communicating with the interval corresponding to the through holes 1531. ci1
It has 11. Furthermore, a plurality of through holes 551 are formed on both side edges of the upper plate 60). This through hole 69 is a cold air passage (1
30+ and the space between the upper plate 60) and the insulation material 62, and these through holes 60) 541531 connect the cold air passage (7) and the refrigerator compartment (9) inside the partition plate (8). A cold air passage is constructed. The case (10) is fixed to the upper edge of the sloped surface of the upper plate (5) on the inner side than when the hole is opened, and the cold air passages t5+, + are fixed to the sloped part (5) around the partition plate (8).
Due to the shape of the upper plate (5 (1)), it slopes inward and descends from when the hole is opened, and wraps around the lower surface of the upper plate (5 (1).

The partition plate (8) assembled in this way is attached to the front member 12.
■It can be mounted almost horizontally by engaging both edges with the inner box (concave groove r57 formed on both side walls of 4η) above ■, but since the central horizontal part is recessed than the edges, the front member Located behind the prisoner. Therefore, the dead space inside the refrigerator behind the front member can be used effectively, and the cold air circulation path is formed as long as the partition plate (8) is recessed and there is enough space above the case 00 to accommodate the arm G2. Since the upper surface of the case can be brought close to the lower surface of the partition wall (3) without the need for cooling, the internal volume of the ice room α2 can also be expanded.

The front part ■ has one step below the center at the rear of the top surface (20A)
is formed and has one or more ribs (60) projecting rearward on the rear surface. On the other hand, the partition board (8)
There is a lip (6
One or more supporting walls 61) extending vertically are provided in a protruding manner corresponding to the partition plate (8). is prevented from sagging due to the weight of stored items or its own weight, and maintains the distance between the rear surface or stepped portion (20A) of the front member (2) and the sloped portion (8A) of the partition plate (8). At this time, the front edge of the upper plate r5■ of the partition plate (8) extends to the upper part of the step part (20A) of the front member ■, covers it with a gap therebetween, and furthermore has a plurality of through holes 6. is formed. In addition, there is a gap between the door (27J and the inner door circle), and the upper end is connected to the cooling chamber (13) through the suction hole formed in the lower front part of the partition wall (3), and the lower end is connected to the cooling chamber (13) through the through hole ( 6Z allows the refrigerator compartment (9
), forming a series of cold air return passages. Here, (69 is a cold air suction hole on the freezer compartment (4) side).

Next, cold air circulation will be explained. The cold air blown out from the discharge port C35+ of the damper thermo cover (C) flows into the cold air passage (2&), collides with the front wall of the molded insulation material cover, and is distributed to the left and right. ), frost will not form on the outer surface of the concave groove (5) of Kennis (10).The cold air flowing from side to side in the cold air passage will pass through the cold air passage on the side of the case (101) as shown by the arrows in Fig. 2. (to) and descends, and from the time of the through hole, it flows into the cold air passage (-).The cold air that has flowed into the cold air passage ), but most of it is well guided toward the center.As a result, the inside of the ice chamber (12) is indirectly flowed from both sides of case a■ and the upper plate (50) of the partition plate (8). The case (l
By not circulating cold air over the upper surface of the o+, prevention of frost formation on the upper surface and expansion of the internal volume of the ice chamber 02 can be achieved, but the cooling effect may be insufficient. Therefore, a through hole [F]Q is formed in the side part of the bottom wall corresponding to the cold air passage @ of the molded heat insulating material (2 sickles), and a corresponding through hole (6η) is bored in the case 001. The cold air b' in the cold air passage (c) is directly introduced into the ice chamber (1'2), and the installation of the refrigerator (1) accelerates the cooling rate of the ice chamber α2, and also Eliminate insufficient cooling.

In addition, at this time, the cold air flowing in from the through hole (6η) flows into the ice room 0z from both sides and has a velocity to the left and right, so it flows forward along the inside of the side of the case (11), and the stored food Furthermore, since the amount of cold air flowing in is small, drying of the stored food is suppressed to a minimum. Through such indirect and direct cooling, the inside of the ice room α2 is kept cool at the freezing temperature storage temperature. .Here, the freezing temperature storage temperature is a temperature range such as 0°C to 12°C, which is below freezing but just before meat and vegetables freeze.By storing food at this freezing temperature storage temperature, it can be frozen. It suppresses the growth of bacteria inside and can be stored for a relatively long period of time (about a week in experiments).

The cold air flowing into the cold air passage Q flows through the through hole ■6a to the refrigerator compartment (9).
) and circulates with the cold air from the side outlet (2e) inside the refrigerator compartment (9) and around the container (6) to exchange heat, and then the partition plate ( 8) and the front member (A), rises along the outer surface of the inner door (11), ascends the cold air return passage (64J), and returns to the cooling chamber (13) through the suction hole (to). There is an upward air current near the door (221 or (c)) due to heat leak from outside the refrigerator.
This cold air return operation will also be achieved smoothly. Also,
Since an upward air current is constantly generated in front of the inner door 0D, the transparent inner door 0D will not become cloudy due to condensation or the like, and the visibility inside the low-temperature ice greenhouse z will always be maintained well.

Since the damper 'thermo (lCJ) senses the temperature of the refrigerator compartment (9), changing the set temperature of the refrigerator compartment (9) will also change the amount of cold air flowing into the cold air passage (to).
By moving the damper plate (b) left and right and adjusting it appropriately, the temperature inside the ice room 0 can be maintained at a predetermined ice temperature storage temperature.

(g) Effects of the Invention According to the present invention, the structure of the compartment is easy, and since the top plate of the compartment plate has a concave shape, the dead space behind the front member is effectively used to expand the internal volume of the compartment. I can do things. In addition, since the upper plate has an inclined shape, the cold air from the outside of the case is accelerated when flowing into the cold air passage on the lower surface along the upper plate, and is well introduced into the partition plate, so that the compartment is located on the upper side. Cooling becomes uniform over almost the entire area of the plate.
