Abstract

PURPOSE:To make it possible to use a wider space indoor, be more convenient for indoor cleaning, and maintain cleanness of a room, by setting a partition wall 10 filled with insulation so that it may be thinner than a front stiffening plate, and installing a guide rail for an independent chamber door on a level difference section thus produced. CONSTITUTION:A refrigerating chamber 5 and a partial chamber 6 are divided by a partition wall 10 filled with insulation. On the front there exists a backing plate 12 fixedly fitted between a front stiffening plate 11 and the partition wall 10. In the lower part of the partial chamber 6 is installed an independent chamber 15. A top board 16, which serves as a storage shelf, is placed on a guide rail 18. A transparent independent chamber door 17 is fitted to a guide slot 19 of a guide rail 18 as if sliding with a guide pin 20 of the independent chamber door so that it may be opened and closed freely and thus forms the independent chamber 15. The partition wall 10 is made substantially on the same level with the backing plate 12. However, at a side wall 10c, the thickness of the partition wall 10 is arranged to be smaller, thereby producing a level difference d with the front backing plate 12. The guide rail 18, which is substantially identical the level difference d in terms of thickness, is provided so that is may be substantially on the same level with the backing plate 12. A front member 18a of the guide rail 18 is extended to the backing plate 12 and is placed into contact with the backing plate 12, thereby minimizing the roughness in the partial chamber.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention has a plurality of storage chambers, at least two of which
This invention relates to a refrigerator that has chambers arranged side by side and a partition wall filled with a heat insulating material.

BACKGROUND ART A conventional example will be explained with reference to FIGS. 3 to 5. In the figure, a refrigerator main body 1 is formed into an oval shape by an outer box 2, an inner box 3, and a heat insulating material 4 filled between the two boxes. The main body 1 consists of a plurality of storage compartments, including a freezing compartment 6 at the upper right side, a partial compartment 6 at the upper left side located side by side, a refrigerator compartment 7 at the center right side, and a vegetable compartment at the lower right side. 8. It consists of an accessory compartment 9 at the lower left side. Each storage chamber is divided by a partition wall and independently temperature controlled. The freezer compartment 6 and the partial compartment 6 are divided by a partition wall 1o filled with a heat insulating material 4, and a front plate 1 is provided at the front of the partition wall 10.
1. A back plate 12 is installed between the front plate 11 and the partition wall 10.
are fitted and fixed.

Inside the partial chamber 6, a storage shelf 13 for storing stored food is placed on a shelf support 14, and an independent chamber 16 is provided at the bottom, and a top plate that also serves as a storage shelf. 16 is
Placed on guide rail/L/18, and transparent independent room door 17
is engaged with this guide rail/I/180 guide groove 19 so as to be freely openable and closable so as to slide the guide bin 20 of the separate room door, which is separately described.
An independent room 16 is formed. Further, a temperature control device 18 is housed in the back of the independent chamber 16, and controls the amount of cold air supplied to the partial chamber 6 through the action of a built-in damper thermo, thereby keeping the temperature constant within the partial temperature range. .

In the above configuration, the frontage width dimension a of the partial chamber 6 is set by the front abutment plate 11 and the inner box 3. In addition, the partial chamber interior width dimension is the front abutment plate 11.
It is set by the side wall 10a of the partition wall 10 marked with Nil and the side wall 3a of the inner box 3 marked σ, which have a substantially concave surface, but the side wall 1 of the partition wall 1
Both the inner box side wall 3a and the inner box side wall 3a are inclined toward the partial chamber θ side due to the draft angle provided to facilitate removal from the mold during molding of the inner box #A3.
The frontage width dimension is smaller than a. The relationship at this time is a
>b. On the other hand, the partition wall 1o adiabatically partitions the freezing chamber 6, which is cooled to -18°C, and the partial chamber 6, which is cooled to -3°C, by means of a polyurethane foam insulation material 4 filled inside. . This partial chamber 6 maintains the freshness of the prize for a long time by keeping the moisture contained in the prize in a frozen state. Since it is necessary to minimize not only the outside temperature but also the heat transfer with the adjacent freezer compartment 5, a thick insulating wall is required. The guide pin 20 provided protrudingly is engaged with the guide groove 19, and the guide pin 20 slides along the guide groove 19, causing the guide pin 20 to move downwardly as shown by the two-dot chain line in the figure. The guide rail/L/18 is designed to open upward from the top to allow the food stored inside to be taken out.However, for the reasons mentioned above, this guide rail/L/18 has a partition wall of 1°. Since it cannot be made concave and thin, it is provided so as to protrude from the side wall 10a.A guide rail is also provided opposite to the side wall 3a of the inner box, and the width dimension C between the guide rails 18 is equal to the partial guide width. Yoshi also becomes smaller, and the relationship becomes b > c, and the guide rail /l
/18 thickness d is smaller by a total of 2 pieces on the left and right sides. Therefore, the relationship including the frontage width dimension is a'') b > c,
Also, c=a-2d.

Problems to be Solved by the Invention However, in the above configuration, when the freezer compartment 5 and the partial compartment 6 are installed side by side, the partial compartment 6 has a wider width due to the general ratio of the amount of food stored therein. Since the dimensions are set narrow, there is a limit to the size of stored food,
In addition, it is difficult to take in and out the stored food, and since the guide rail 18 is provided protruding from the inner box side wall 3a and the partition wall side wall 10a, the width of the food that can actually be stored is C.
As shown in the dimensions, it is smaller than the frontage dimension a and the interior width dimension, and the unevenness inside the partial compartment makes it easy to get dirty due to food juices accumulating, making it difficult to clean the interior that should be kept clean. There were some issues, such as difficulty.

The present invention solves the above-mentioned conventional problems, and eliminates protrusions such as guide rails on the independent room door of the storage room, making the room wider and easier to clean, thereby making it possible to keep the room clean. is aimed at something.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention fills a partition wall that partitions a storage room with a heat insulating material, makes the wall thickness smaller than the front plate, and separates the partition wall from the front plate. A guide rail for a door of an independent room in a partial room is provided at a stepped portion formed by a wall.

IchikawaThe present invention, in accordance with the above-mentioned structure, widens the width of the independent room door guide rail portion in terms of the frontage and the space, thereby reducing unevenness in the room.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. The refrigerator main body 1 is composed of an outer box 2, an inner box 3, and a heat insulating material 21 filled between the two boxes and having a lower thermal conductivity than the conventional one. The freezer compartment 6 and the partial compartment 6 are divided by a partition wall 1o filled with the heat insulating material 21, and a front abutment plate 11 is provided at the front of the partition wall 1o. A back plate 12 is fitted and fixed between the base plate 1o and the base plate 1o. In the upper part of the partial chamber 6, a storage shelf 13 for placing stored food is placed on a shelf support 14. Further, an independent room 16 is provided at the lower part, and a top plate 16 which also serves as a storage shelf is placed on the guide rail A/18, and a transparent independent room door 17 is placed on this guide rail 180 and the guide groove 19. The guide pin 2o of the independent chamber door is slidably engaged with the guide pin 2o to form an independent chamber 16. A temperature control device 18 is housed at the back of this independent chamber 16. The partition wall 10
The cold side storage compartment 5' (in the III wall 1ob, it has a substantially concave drawing with the back plate 12, but in the partial compartment e side side wall 10a, the thickness of the partition wall 1o is set small. Therefore, a step d is formed between the front contact plate and the back plate 12.The guide rail 18 is arranged so as to form a substantially concave plan with the back plate 12 with a thickness between the step d and the track. It is set up.

In the above configuration, the frontage dimension a of the partial chamber 6 is the same as the 8 dimensions shown in the conventional example.

In addition, the width e of the partial chamber is set by the inner box side wall 3a and the partition wall 10a which are inclined toward the interior side of the partial chamber 6, but because the step d is provided, the width e is different from the width a. It's getting bigger.

The relationship at this time is e > a. Although this partition [10 is set thin, since it is filled with the heat insulating material 21, the temperature is not affected by heat transfer from the freezer compartment 6. The independent room door 17 provided in the partial room e has a guide rail 18
The guide pin 2o slides along the guide groove 19 of the guide pin 2o, so that the guide pin 2o can be opened and closed freely. Since the partition wall 1o side of this guide rail IV1B is provided at the stepped portion d, the width f between the guide rails 18 is narrower than the frontage dimension a, but it is only reduced by the thickness of the guide rail 181. It is. That is, the relationship is f = a - d. Therefore, compared to the partial chamber frontage dimension a, the indoor width dimension e, which is the effective width dimension, can be made larger, and even at the narrowest distance between guide rails f, the thickness d corresponding to 181 guide rails becomes narrower. This allows the interior width e to be used as effectively as possible. Furthermore, by extending the front part 18a of the guide rail 18 on the partition wall 1o side to the back plate 12 and bringing it into contact with the back plate 12, it is possible to create a substantially concave drawing with the back plate 12, thereby reducing unevenness in the partial chamber. Can be done.

Effects of the Invention As described above, in the present invention, the partition wall filled with a heat insulating material is set thinner than the front panel, and the guide rail for the independent room door is provided at the step formed by the partition wall. The width dimension can be set large, making it possible to store food more effectively.In addition, it is possible to reduce unevenness in the room, which prevents dirt from accumulating from food juices, etc., and makes it easy to wipe clean even in dirty areas. It is suitable for food storage as it can be easily cleaned and the room can always be kept clean and sanitary.
