Description

[Detailed Description of the Invention] The present invention relates to a fixing structure for a high-pressure side refrigerant pipe of a refrigeration unit as a heating element for preventing sweating at the front opening edge of a refrigerator body.

Generally, in refrigerators where there is a temperature difference between the inside and outside of the refrigerator, condensation occurs at the front opening of the main body, where heat leaks easily, that is, near the area where the door meets the door.

Needless to say, this condensation wets the outer surface of the refrigerator body, causing rusting on the iron parts, and also wets the floor surface on which the refrigerator is installed, necessitating careful handling.

In order to prevent such dew condensation, a method has often been used in which an electric heater cord for heating is disposed in the condensation area.

These electric heater cords were preferred because they are highly flexible and can be easily placed on the back side of the opening of the outer box that takes over the main body of the refrigerator.

However, using an electric heater cord for the sole purpose of heating is not preferable in terms of the amount of electricity used.

Therefore, it has been known to utilize the heat radiation of the hot gas pipe (high-pressure side refrigerant pipe) of the refrigeration unit, which has the same amount of heat as the electric heater cord, and to arrange the hot gas pipe in the same way as the heater cord.

However, these hot gas pipes are connected to the refrigeration unit and are made of metal pipes, so the bending process is difficult.
Not only is it difficult, but it is also difficult to install piping in an effective heat exchange relationship in the condensation prevention area.

A modern refrigerator with an open front box divided into upper and lower compartments by a partition wall, with the upper compartment serving as the freezer compartment and the lower compartment serving as the refrigerating compartment, each with an independent door body. If the hot gas pipe of the refrigeration unit is piped in a ring only around the opening of the outer box as in the past, the hot gas pipe for preventing sweating will not be piped against the partition wall that separates the freezer compartment from the refrigerator compartment.

Therefore, if you introduce a hot gas pipe to the partition wall side from the middle of the annular piping, make a U-turn at the tip, and lead it out again to create a complicated piping structure, the hard metal pipes will float against the partition wall and heat up. There was a drawback that the exchange relationship could not be followed reliably and that effective prevention of sweating could not be achieved.

In addition, in order to uniformly heat the front panel of the partition wall, it is necessary to install hot gas pipes along almost the entire length of the front panel of the partition wall, but if the U-turn section is installed on the door body pivot member side, There is a risk that the screws, etc. of the pivot member mounting part may hit the U-turn part and cause damage, so the U-turn part must be placed at a sufficient distance from the pivot member, resulting in insufficient heating near the pivot member. There was a drawback that dew condensed on this insufficiently heated area.

The present invention was devised in view of this point, and is a method for effectively piping a hard metal pipe against a partition wall.The following is an example of the invention, which is explained with reference to the drawings.1 is a refrigerator body, an outer box 2
An inner box 3 is installed inside the main body, and a heat insulating material 4 is filled between the two boxes, and a partition wall 5 is provided to divide the main body into an upper part, with the upper part serving as a freezing compartment 6 and the lower part serving as a refrigerating compartment 7. There is.

Separate freezer compartment door bodies 8 and refrigerator compartment door bodies 8' are pivotally connected to the front openings of these compartments 6 and 7 so as to be openable and closable, respectively.

A partition wall front plate 9 is attached to the front end of the partition wall 5 that separates the main body into a freezer compartment 6 and a refrigerator compartment 7, and magnets attached to the two door bodies 8, 8' are attached to the partition wall front plate 9. built-in gasket)
10 and 10 are abutted against each other, and a pivot member 11 is fixed to one end of the front plate 9 of the partition wall for pivotally attaching both the door bodies 8 and 8'.

A hot gas pipe 12 is a refrigerant pipe located on the high-pressure side of the refrigeration unit (not shown), and a flange 13 is formed by bending the opening edge of the outer box 2 at the front opening edge 1a of the main body 1. This prevents dew condensation from a portion of the flange 13 on the front opening side of the main body, which is easily cooled by the low temperature of the freezer compartment 6 and refrigerator compartment 7, which are piped to and maintained at a low temperature, and are prone to heat leakage.

The hot gas pipe 12 is disposed continuously on the back surface of a flange 13 formed by bending the edge of the opening of the outer box 2, and is also bent integrally at the partition wall 5 to form the flange 13.
The flange 13 of the outer box 2 is disposed in close contact with the back surface of the partition wall front plate 9 from the back surface, and the flange 13 of the outer box 2 is placed in close contact with the back surface of the partition wall front plate 9 at one end of the partition wall front plate 9, that is, on the back surface of the mounting portion of the pivot member 11. The introduction part 14 of the hot gas pipe 12 toward the back surface of the plate 9 and the lead-out part 14 from the back surface are bent, and the pipe 12 is formed at the other end.
The U-turn portion 15 of is positioned.

A hot gas pipe 1 located on the back side of the partition wall front plate 9
2 connects the introduction part 14 to the mounting bracket 16 of the pivot member 11.
When the pivot member 11 is attached, it is clamped to the back surface of the partition wall front plate 9.

Therefore, the bent part 17.17 of the hot gas pipe 12, which is a metal pipe formed in the introduction part 14, is bent and becomes harder than other parts, and it is particularly effective because it comes into close contact with the back surface of the partition wall front plate 9. Although it is difficult to install the mounting bracket 16 in
By clamping the hard part together with the pivot member 11, the pipe is securely fixed to the front plate 9 of the partition wall, and accordingly, the straight pipe part 18 up to the U-turn part 15 formed at the tip is tightly connected to the front plate 9 of the partition wall. It is arranged as follows.

As mentioned above, the present invention divides the main body into two upper and lower parts with a partition wall, and arranges a hot gas pipe, which is the high-pressure side refrigerant pipe of the refrigeration unit, at the front opening edge of the main body, and a part of the hot gas pipe. A pivot part that is continuously bent from the flange side of the outer box to form a straight pipe part and a U-turn part, and inserted into the back side of the front plate of the partition wall, and that pivots the door body that opens and closes the two units. The introduction part and the outlet part of the hot gas pipe are located on the side where the material is disposed, the U-turn part is located on the other end side, and the pivot member mounting part is located between the introduction part and the outlet part. Therefore, when installing the pivot member, the U-turn part, as well as the inlet and outlet parts, can be easily separated from the support screws of the pivot member without avoiding heating of the vicinity of the pivot member, and the hot gas pipe can be easily separated. Since there is no damage, there are no restrictions on the mounting position of the pivot member, making the design and installation work extremely easy. It can promote uniform heating of the wall front plate.

Furthermore, since the introduction part and the outlet part of the hot gas pipe are on the side of the pivot member, even if the mounting position of the pivot member located between the introduction part and the outlet part is slightly shifted, the position of the introduction part and the outlet part can be finely adjusted. It is easy to do so, and strict precision is not required for the mounting positions of the partition wall front plate and pivot member, and the design and manufacturing process can be simplified.
