[Industrial applications]

 The present invention relates to a condenser pipe fixing device for condensing a refrigerant in a cooling device such as a refrigerator or a freezer, and is intended to reliably fix a condenser pipe.

[0002]

[Prior art]

 Conventionally, cooling devices such as refrigerators and freezers are provided with condenser pipes. As this condenser pipe, it is known that a thin pipe is formed in a meandering shape by providing a plurality of U-shaped bent portions at regular intervals. Since this condenser pipe itself cannot maintain its strength, it is necessary to provide a certain amount of reinforcement when it is attached to the cooling device body. Examples of the reinforcing method include the device described in Japanese Utility Model Publication No. 46-11797, the device described in Japanese Utility Model Publication No. 56-85276, the device described in Japanese Utility Model Publication No. 58-165576, and the Japanese Utility Model Publication No. 58-165580. There are ideas mentioned.

[Problems to be solved by the device]

 In the conventional device described in Japanese Utility Model Publication No. 46-11797, a plurality of long holes are opened in an L-shaped fixed body, and a U-shaped bent portion of a condenser pipe is inserted into the long holes. Fixing the condenser pipe.

However, in this conventional method, when the bent portion of the condenser pipe is formed, the bent portion cannot be properly inserted into the elongated hole of the fixed body unless the pipe is bent accurately. . Also, with this conventional method, once the oblong holes are opened, the interval between the oblong holes cannot be changed, so there is a drawback that it cannot be used for condenser pipes where this interval does not match the interval between bent parts. Had.

In the device disclosed in Japanese Utility Model Laid-Open No. 56-85276, fixed pipes that also serve as heat radiation are welded and fixed to the front and back sides of the condenser pipe. However, in this conventional method, since there are many welding points between the condenser pipe and the fixed pipe, the welding work requires a lot of time and labor, and the cost is high.

Further, the inventions described in Japanese Utility Model Laid-Open Nos. 58-165576 and 58-165580 form a duct for covering a condenser pipe, and a bent portion of the condenser pipe is provided inside the duct. An engaging piece that is fixedly fitted is provided. However, in this conventional method, since it is necessary to form a plurality of engaging pieces corresponding to the bent portions, it takes time and labor to manufacture and the cost is high. In addition, in this conventional method, the engaging pieces are fixedly formed so that they cannot be moved.Therefore, for condenser pipes in which the distance between the engaging pieces and the distance between the bent portions do not match, It could not be used.

The present invention is intended to solve the above problems, and when a condenser pipe is fixed to a cooling device body such as a refrigerator or a freezer, it can be fixed easily and surely. It does not take time and effort and is done at a low price.

[0008]

[Effect of device]

 Since the present invention is configured as described above, when fixing a condenser pipe to a cooling device body such as a refrigerator or a freezer, the condenser pipe is folded between both side walls of a fixed main body having a U-shaped cross section. This is done by inserting the music part.

Therefore, the bent condenser pipe is integrated and reinforced, and there is no possibility that the bent portion may fall off between the both side walls without permission, so that reliable fixing is possible. Moreover, since the fixed body is provided in a U-shaped cross section, the structure is simplified and the molding becomes easy.

Moreover, since the both sides of the fixed main body are continuously formed, the bent portion can be inserted from anywhere between the two side walls. Therefore, even if a plurality of types of condenser pipes are formed by changing the interval between the bent portions, the plurality of types of condenser pipes can be fixed by the same fixing body, which enables rational fixing.

In addition, the fixed main body can be further connected and fixed by inserting the bent portion of the condenser pipe between both side walls and then connecting and fixing the both side walls at regular intervals in this insertion state. It is possible.
