Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention relates to a refrigerator in which compartments are formed within the storage space. With the diversification of the interior, compartments that are cooled to various different temperatures have been formed.
, J, SuAhζ ■ phase There are also systems that cool the interior indirectly through the walls that form the compartment in order to suppress the deterioration of metal parts. For example, in this kind of indirect cooling system,
There is a publication No. 23381.

(c) Problems to be solved by the invention In such a configuration, there is a partitioned room (cold room) and a lower storage room space (
The partition wall between the compartment and the refrigerator compartment is just a plate, so if a large amount of heat load (for example, food that has just been cooked) is stored in the storage space below, the temperature inside the compartment will also be affected by the heat. It will rise.

Such drawbacks are particularly significant in those with lower cooling temperatures within the compartment.

B.) Means for Solving the Problems In order to solve these drawbacks, the present invention divides the inside of the storage room with a partition plate (8), and the partition plate (8) forms a partition that forms a wall. Comprising the compartment α2, the partition plate (8) is connected to the first plate ('50) facing the compartment α2 and the other storage compartment (91).
Assembled from the molded insulation material (521) loaded between the second board 6υ of OL11 and the drawing board (50+5υ), molded insulation material CJ
A cold air passage (56) is formed between the first plates 60) and cold air under internal pressure is introduced into this cold air passage (56).

(E) Function According to the present invention, the compartment interior is insulated from other storage compartments, and the influence of heat from there can be prevented.

Furthermore, a cold air passage is formed in the partition plate, which contributes to cooling the compartment and also facilitates assembly of the partition plate.

(f) Embodiment An embodiment will be explained with reference to the drawings. Fig. 6 shows a refrigerator (1) as an embodiment. (2) is a heat insulating box that opens at the front, An insulating partition wall that separates the inside of the refrigerator.
A freezer compartment (4) is formed above it. (5) is a partition plate which is located at the lower part of the refrigerator and has a vegetable compartment (7) formed by a container a (6) below it. Partition wall (3) and partition plate (5

An ice chamber 02 as a compartment is formed by υ. A cooling chamber 031 is formed within the partition wall (3),
A cooler α4 included in the refrigeration cycle is housed here. After the cooling chamber t131, a duct (1506+) is formed that communicates with it and extends vertically, and a blower (1506+) is formed.
71 is arranged. The blower α is operated and the cooler (1
Cold air from duct 41 is sent out to the freezer compartment (4) from 15i (sent in the 16! direction, duct) Q5i. Duct (IQ is case 00) is opened in the back wall of the insulating box body (2) at the rear. Cold air is discharged from the discharge port t181, and this discharge port u81 is controlled to open and close by a damper thermo I that senses the temperature inside the refrigerator compartment (9).

The partition plate (8) has a front member provided at the lower opening edge of the partition wall (3) from left to right and located at the rear. Also, (21(
22) θ and (2 townhouses each have a freezing room (4) and an ice room (
This is due to the insulating properties of the openings in the refrigerator compartment (9) and vegetable compartment (7) at the front of 101, which are closed in the opening/closing manner.

FIG. 1 shows an enlarged side sectional view of the ice chamber 02, and FIG. 2 shows a front sectional view thereof. Furthermore, FIG. 3 shows an exploded perspective view of the ice room a3. (29 is the damper thermo cover, which has a heat insulating material inside, the case frame and the heat insulating box body (2)
It is located between the back wall and has three discharge ports that allow the cold air flowing out from the discharge outlet to flow directly into the refrigerator compartment (9), and a discharge port that discharges the cold air forward. On the rear upper surface of the case (101), two grooves are formed that span the entire width of the case (101), and two grooves are formed in the upper and left sides of the groove cylinder to form a cold air passage for distribution from side to side. The open molded heat insulating material c29) is housed.The left and right sides of the case (+01) form a cold air passage 00 which communicates with the cold air passage 4 with a space between both sides of the inner surface of the insulating box (2) as shown in Figure 2. At this time, the opening edge and back of the case (1) are connected to the partition wall (
3) It is in contact with both the lower surface and the inner surface of the insulation box (2).

The case (+01 upper surface has a small distance between the partition walls (3) and has a projection c31 projecting upward in the center). An operating arm C32 is rotatably fixed to this protrusion (31), and a damper plate (2) rotatably engages with the elongated hole formed at the center end of this arm (321). It is formed by integrally forming the opening/closing plate (4) located at the back and the closing plate (4I) located in front of it.
(To) It opens in the center of the mountain, and the opening/closing plate (41 is located at the cold air passage (discharge port G5 in 281) +L Air. The knob at the front end of arm 0'2 (43 is the inner door) 0
It is exposed on the back side of υ, and by operating this knob (421 left and right), it is possible to adjust the amount of cold air flowing into the cold air passageway through the discharge port C35. In addition, a lip (43) that protrudes upward is formed on the front edge of the concave groove frame to prevent cold air from flowing into the top surface of the case U. Correspondingly, a notch (29A) is also formed in the heat insulating material (2).

A closing plate (411) is located just in front of this notch (2). This closing plate (4υ) always closes the notch (44J) even if arm G2 moves left and right. This closing plate (4I) and the rib (
49 prevents the cold air from flowing into the upper surface of the case (10), so that the cold air stays here, thereby preventing the inconvenience of frost formation on the upper surface of the case (10). (c) is a cover that closes the upper opening inside the molded heat insulating column.

The partition plate (8) assembled in this way has a recess @6 formed on both side walls of the inner box (47) above the front member ■.
7) by engaging both side edges and attaching it approximately horizontally, but since the central horizontal part is recessed than the edges, it is located at the rear of the front member. Therefore, the dead space inside the refrigerator behind the front member (20) can be used effectively, and if the compartment & (8) is recessed and there is enough space above the case (11) to accommodate the arm (321), it will be possible to air cool air. case without configuring the aisle (
By allowing the upper surface of 101 to be close to the lower surface of the partition wall (3), the internal volume of the ice chamber (12) can also be expanded.

) is the cold air intake hole.

Next, cold air circulation will be explained. The cold air blown out from the discharge port ζ of the damper thermo cover (251) flows into the cold air passage (domestic), and once collides with the front wall of the molded insulation material (251) and is distributed to the left and right.At this time, the molded insulation material (29) Due to the presence of the case (101), frost does not form on the outer surface of the concave groove (27).The cold air flowing from side to side in the cold air passage (C) is as shown by the arrows in Fig. The cold air flows into the cold air passage (5e) through the through hole mark. Due to the sloped shape of the cold air passage (5e), the cold air does not immediately flow down through the through hole f53154 at the side end. Most of the ice is guided well toward the center.As a result, the inside of the icehouse 03 is indirectly cooled by the case (both sides of the IQ and the upper plate (51) of the partition plate (8).
) by not allowing cold air to circulate on the top surface
The cold air passage of the insulation material 12!11 is formed with through holes (66) on both sides of the bottom wall corresponding to the layers, and corresponding holes (66) are formed in the case 4. Through this, the cold air in the cold air passage (c) is directly introduced into the ice chamber (17J), although it is small in size. This speeds up the cooling rate and eliminates the lack of cooling caused by indirect cooling.

At this time, the cold air flowing in from the through hole (6η) flows forward along the inside of the side of the ice chamber (case 00 since it flows into the ice chamber (12+) and has a speed to the left and right from both sides).
It flows to wrap around the stored food. Since the amount of cold air flowing into the container is small, drying of stored food is suppressed to a minimum. Through such indirect and direct cooling, the inside of the ice room α2 is kept cooled to the freezing storage temperature. Here, the freezing storage temperature is a temperature range that is below freezing, such as 0°C to -2°C, but just before meat and vegetables freeze.By storing food at this freezing storage temperature, it can be frozen. It suppresses the growth of internal bacteria and lasts for a relatively long time (about a week in experiments).
You can save it.

The cold air that has flowed into the cold air passage 66) flows down into the refrigerator compartment (9) through the V1 hole ω, circulates inside the refrigerator compartment (9) and around the container (6) together with the cold air from the side outlet +2til, and generates heat. After the replacement, as shown by the arrow in FIG. It returns to the cooling room a3 from the suction hole.J) At around t221 or (c), an upward air current is generated 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 inside υ, the transparent inner door αD is not clouded by condensation or the like, and visibility inside the low-temperature ice room Q21 is always maintained at a good level.

Here, the damper thermo■ senses the temperature of the refrigerator compartment (9), so if you change the set temperature of the refrigerator compartment (9), the cold air passage □□
The amount of cold air flowing into □ also changes, but by moving the damper plate (2) left and right using the knob (42) and adjusting it appropriately, the temperature inside the ice room a can be maintained at the predetermined ice temperature storage temperature. can.

(G) Effects of the Invention According to the present invention, the room N and other storage spaces are insulated by the molded heat insulating material in the partition plates, so they are not affected by heat from other storage spaces, and especially Temperature control becomes accurate, such as when cooling the inside of a compartment to a low temperature. Further, since a cold air passage for cooling the inside of the compartment is formed in the partition plate, the cooling inside the compartment is improved, and the partition plate can be easily assembled.
