Description

DETAILED DESCRIPTION OF THE INVENTION The present invention makes it possible to fully utilize the volumes of the freezing and refrigerating compartments, and also provides high productivity and safety.
This relates to a refrigerator whose main purpose is to obtain a refrigerator I'11j.

In the so-called two-temperature type refrigerator that has a conventional freezer compartment and a refrigerator compartment, there is a blank space inside the inner box. The most common method is to incorporate a separate internal partition JIj,'j, which forms a V-shaped section inside the inner box into a freezer compartment and a refrigerator compartment. Because it required a separate wall and a built-in AT, it could not be said to be a good refrigerator.

The cold epsilon 1 has improved this point! This was a t'N warehouse in which the inner box for the refrigerator compartment and the refrigerator compartment were integrally formed, and a foam insulation material was filled between the inner box and the outer box.

However, in this type of refrigerator, installation of a cooler for cooling the freezing and refrigerating compartments becomes a problem.

This is because refrigerators that use a partition wall have
Medium q4. The cost of installing the cooler is to forcibly send cold air to the freezer and refrigerator using a fan.4"14

Refrigerated, room -1-$ 4: , change, turn, no city, unai,
In the case of a box, 1.1 It is not possible to install the cooler because the partition wall where the cooler was previously installed is filled with foam insulation material.

Therefore, in conventional refrigerators, it is usually a good practice to install separate coolers in the freezer compartment and the refrigerator compartment. □ ′ □ However, there are some arbitrary arguments regarding this type of rootstock in the refrigerator.
・ ,・ 1. When installing a cooler in the freezer and storage compartments, install the cooler into the inner box that encloses the freezer and refrigerator compartments.
Since there is a threat of
, it is difficult to prevent foam insulation from leaking from these holes.
It becomes a chore.

(This also applies to the type of cooler that is built in after foaming and filling with insulation material.) In the refrigerator, there is a freezer compartment.

□ Not only does the internal volume of the bathroom decrease, but the cooler □
□: Since the surrounding area also becomes a dead space, when comparing the storage volume with and without cooling/components, it can be said that this type of equipment is generally inefficient.

In order to improve this defect, the present invention temporarily fixes the cooling evaporator pipe to the inner box P2 side that forms the freezer compartment and the refrigerator compartment so as to wrap it around the back surface of the freezer compartment and refrigerator compartment, and then 1,',... +i Filled with foam insulation material between the inner box and outer box

The details of the present invention will be explained below with reference to an embodiment shown in the drawings. 1 is a refrigerator main body, 2 is a refrigerator body, 3 is an outer box that forms the appearance of the main body 1, and 3 is an inner box made of synthetic resin that integrates the freezer compartment 3a and the refrigerator compartment 3b. 4 is the foam insulation material filled between the inner box 3 and outer box 2, 5 is the compressor, 6 is the condenser, □7 and □ are the cabinet/bow 4 tubes, and 81 Yogi are the original parts for cooling the refrigerator room. 9 is an evaporator pipe for cooling the freezer compartment, 10 is a header, and 11 is a suction pipe. These item numbers 5 to 11 are connected in series or in a ring to form a refrigeration cycle.

However, some of the filtering medium that passed through the capillary tube 17 evaporated? (8 parts are evaporated first, and then all are evaporated in the evaporator pipe IO.) In this way, the freezing chamber 3a' and the refrigeration chamber 3b' are kept at the prison temperature. be.

In this configuration, the evaporator pipes 8 and 99 used in the present invention will be explained with reference to FIG.

This groove 12 is connected to the evaporator pipe 8 (9) as shown in -.
The aluminum tape 13 wraps around most of the outer circumference, and when the evaporator pipe is installed, the aluminum tape 13 absorbs the influence of the pipe 8 (9).
It is designed so that it can be pasted on any surface without causing any damage.

Steam generator pipe 8. ．． (, 9,) are removed and attached to the inner box surface. Refrigerator compartment 3 b' is provided at the rear wing of the inner box ψ, and freezer compartment 38' is provided at the upper surface, both sides and rear surface of the inner box back surface. ,re,tei,ru. Furthermore, in the present invention, an inner box 3 is provided in order to mount the evaporator pipe 8 (10).
The groove 12 formed in the freezer compartment 38/ is formed in the front and back direction, and the refrigerator compartment 3b' is formed in the vertical direction, and the inner part is used for box forming and defrosting.
□It has been devised to be similar to the defrost water treatment at the time.

The present invention is based on the above theory: As explained above, there is provided a refrigerator in which a cooling/freezing compartment and a refrigerating compartment are integrally formed, and a heat insulating material is filled between an inner box and an outer box by foaming. ．． The evaporator pipe that cools the freezer compartment has a groove that surrounds more than 2/3 of the pipe:
The evaporator/pipe that cools the refrigerator compartment is located on the top and back of the box π surface and on both sides, and the evaporator/pipe that cools the refrigerator compartment is located on the inner box and back.
.

In addition to providing J on the back surface of the
After installing the evaporator pipe and temporarily fixing the evaporator pipe with tape, etc., the inner box is filled with foam insulation material, so it is a good idea to reduce the ineffective volume. Not only can it be cooled to a predetermined temperature without the need for a partition wall, but there are no holes for installing a cooler in the inner box, which improves productivity. In addition, the evaporator pipe and inner box are in efficient contact with each other through the groove.

The unevenness of the groove can secure a depression area that is approximately three times the area where the pipe and pipe are installed on the non-grooved surface, allowing sufficient heat exchange. Since the defrosting water used to defrost the cooling wall surface is guided by the vortex embedded in the evaporator pipe, there is no chance of it dripping into the room.

In addition, in the present invention, used aluminum tape is used on several parts of the inner box of the evaporator pipe, and the aluminum tape is attached to the flange I-side, so that sufficient adhesive strength can be obtained. The evaporator pipe has been carefully inspected and the workability is very good.
