[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a refrigerator, and more particularly to a mounting structure of a defrost heater installed below a cooler.

[0002]

[Prior Art]

 3 and 4 show a conventional defrosting heater supporting device for a refrigerator. In the drawings, reference numeral 1 denotes a refrigerating box body, which is formed between an inner box 1a and an outer box 1b and between the inner box 1a and the outer box 1b. The heat insulating material 1c is filled in the space. The inside of the box 1 is divided into a freezing compartment 3 and a refrigerating compartment 4 by a partition 2, and a freezing compartment door 5 and a refrigeration compartment door 6 for opening and closing the compartment are attached to the front openings of the compartments so as to be opened and closed. ing. A cooling chamber 8 partitioned by a partition plate 7 is formed in the inner portion of the freezing chamber 3, and a blower 9 and a cooler 10 for forced circulation of cold air are vertically arranged in the cooling chamber 8. An air outlet 11 facing the blower 9 is formed in the upper part of the partition plate 7, and a suction port 12 communicating with the freezing chamber 3 is formed in the lower part. Reference numeral 10a is a refrigerant pipe of the cooler 10. The lower part of the cooling chamber 8 is communicated with the refrigerating chamber 4 via a passage 13 formed in the partition 2.

Reference numeral 14 is a defrosting heater arranged below the cooler 10, and 15 is a defrosting heater, which protects the partition 2 from heat of the defrosting heater 14 at the time of defrosting and prevents water droplets dripping from the cooler 10. A dew tray for receiving and leading to the drainage hose 16 is provided with a pair of holding portions 15b formed by cutting and raising on the back wall 15a, and supports the rubber caps 17 at both ends of the upper defrost heater 14. Further, a cap portion 15c that protects the defrosting heater 14 from water drops that are dropped from the cooler 10 during defrosting is cut and raised to be integrally formed with the dew tray 15. 15d is an aluminum tape or the like attached to the rear wall 15a so as to protect the partition 2 from the heat of the defrosting heater 14 in the hole of the rear wall 15a opened to form the holding portion 15b or the cap portion 15c. It is a protective equipment. As a defrosting heater supporting device for this type of refrigerator, the one disclosed in Japanese Utility Model Laid-Open No. 52-130268 has been known.

[0004]

[Problems to be solved by the device]

 Since the conventional defrosting heater supporting device of the refrigerator is configured as described above, when the holding portion 15b that supports the defrosting heater 14 or the cap portion 15c that protects from the water droplets is formed, the intermediate partition is formed in the opened hole. In order to protect 2 from the heat from the defrosting heater 14 at the time of defrosting, a protective tool 15d such as an aluminum tape is required, and moreover, the number of steps for manufacturing the dew tray 15 is large and the holding portion is 15b needs strength to support the defrosting heater 14 and uses a relatively thick material, so there is a problem that processing cost, material cost, die cost, etc. are large and cost is high. It was

The present invention was made in order to solve the above-mentioned problems, and it is possible to support the defrosting heater without providing a holding portion for supporting the defrosting heater on the dew tray, and it is inexpensive. An object of the present invention is to obtain a defrosting heater supporting device for a refrigerator that can be used.

[0006]

[Means for Solving the Problems]

 The defrosting heater support device for a refrigerator according to the present invention is provided with locking portions for locking the refrigerant pipes of the cooler at both ends of the defrosting heater and fixing the defrosting heater to the cooler.

[0007]

[Action]

 The defrosting heater according to the present invention is supported and fixed to the cooler by the locking portions provided at both ends, and the holding portion for supporting the defrosting heater on the dew tray provided for receiving the dew from the cooler is unnecessary. Can be constructed at low cost.

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, the same reference numerals as those used in the related art indicate the same or corresponding portions, and detailed description thereof will be omitted. Reference numeral 17 denotes rubber caps provided at both ends of the defrosting heater 14, respectively, and a pair of front and rear locking portions 18 having a substantially F-shaped cross section which locks with the refrigerant pipe 10a of the cooler 10 are integrally provided above. And is fixed to the lowermost refrigerant pipe 10a arranged in parallel. Reference numeral 18a denotes a claw portion of the locking portion 18, and the outside of the tip has an inclined surface 18b which is inclined inward as it goes upward.

Reference numeral 18c denotes a convex portion formed on a lower portion of the claw portion 18a on the outer wall of the engaging portion 18, and as shown in FIG. 1, the lower surface 18d of the claw portion 18a and the upper surface 18e of the convex portion 18c are coolers. The refrigerant pipes 10a before and after 10 are sandwiched. Further, protrusions 18f are provided on the inner wall of the locking portion 18, respectively, and are provided on the flange 19a at the end portion of the shade 19 that protects the defrosting heater 14 from water drops dripping from the cooler 10 during defrosting. The cap 19 is fixed to the locking portion 18 by fitting in the engaged hole 19b. Further, since the dew tray 15 does not need to have the defrosting heater 14 attached thereto, it does not need to be so strong. Therefore, the dew tray 15 is made of a material thinner than that of the conventional example, and it is not necessary to form the shade 19 either. Therefore, the configuration is simple and inexpensive.

Next, the operation will be described. First, the flange 19a at the end of the shade 19 is inserted between the pair of locking portions 18 provided on the rubber cap 17 at the end of the defrosting heater 14 and is disposed on the inner wall of the locking portion 18. The engagement hole 19b provided on the flange 19a is fitted into the protrusion 18f, and the shade 19 is attached to the defrosting heater 14.

Next, between the refrigerant pipes 10 a arranged in parallel at the lowermost stage of the cooler 10, a pair of locking portions 18 provided in the rubber cap 17 at the end of the defrosting heater 14 and having a substantially F-shaped cross section are provided. Then, it is set in a position where the above-mentioned refrigerant pipe 10a is clamped by the claw portion 18a at the tip and the convex portion 18c provided on the outer wall of the locking portion 18. At this time, since the portion of the tip of the engaging portion 18 that comes into contact with the refrigerant pipe 10a of the claw portion 18a forms the inclined surface 18b, the inclined surface 18b serves as a guide against the insertion, and the engaging portion 18a. Since 18 has elasticity, it can be smoothly attached to the cooler 10.

Although the locking portion 18 is integrally formed with the rubber cap 17 in the above embodiment, a dedicated component for forming the locking portion 18 is provided and the defrosting heater 14 is provided. Although it may be configured to be locked at the end of the locking device, the number of parts increases and the cost is slightly higher, but other effects are the same as those of the above-described embodiment, and the member forming the locking portion 18 is also a rubber member. However, it may be a plastic member or the like.

Furthermore, in the above embodiment, the shape of the locking portion 18 that locks to the refrigerant pipe 10a has been shown as a pair of substantially F-shapes, but any shape that locks to the refrigerant pipe 10a is shown. It may have any shape, and has the same effect as that of the above-described embodiment.

[0014]

[Effect of the device]

 As described above, according to the present invention, the defrosting heater is provided at both ends with locking portions for engaging with the refrigerant pipe of the cooler, and the defrosting heater is fixed to the cooler. There is no need to provide a holding part for supporting the defrosting heater on the dew pan prepared to receive dew, which simplifies the process of making the dew pan and is strong enough to hold the defrost heater. Since it is not necessary, the dew tray can be made of a relatively thin material, and an inexpensive one can be obtained.
