Description

Defrost timer device of refrigerator

The present invention relates to a defrost timer device for a refrigerator that controls a defrost heater that operates to remove the defrost generated in the evaporator when defrost is generated in the evaporator that generates cold air in a refrigerator storing and storing food and the like. The present invention relates to a defrosting timer device of a refrigerator which can be easily mounted on the refrigerator main body by allowing the timing means for controlling the operation time of the heater to be easily mounted on the refrigerator main body without using any additional parts.

In general, a refrigerator includes a compressor for compressing a refrigerant at a high temperature and high pressure, a condenser for condensing the high temperature and high pressure refrigerant compressed at a high temperature and high pressure in the compressor, and converting the refrigerant into a high pressure liquid refrigerant. It consists of an evaporator to produce cold air by evaporating, and a fan motor rotated so that the cold air generated in the evaporator is supplied to the inside of the fresh food storage such as storage.

Such a conventional refrigerator is characterized in that defrost occurs in the evaporator when the compressor that compresses the refrigerant at a high temperature and high pressure is operated for a predetermined time or more. do.

Thus, if defrost occurs in the evaporator by operating the compressor for a predetermined time or more, the compressor is temporarily stopped and the defrost heater is operated to remove defrost generated in the evaporator.

As such, when the compressor is operated for more than a predetermined time and defrost occurs in the evaporator, a defrost timer for controlling the operation cycle of the defrost heater is required to operate the defrost heater. This defrost timer is shown in FIG. 1. It will be installed in the machine room of the refrigerator together.

That is, the defrost timer device of the refrigerator includes a main body 1 for forming the appearance of the defrost timer, and a control unit which protrudes from the main body 1 to control the time to operate the defrost heater and to temporarily stop the operation of the compressor ( 2) and the first, second, and third terminals 4, 5, and 6, which protrude from the lower part of the main body 1 in which the control unit 2 protrudes and are made of a material such as copper.

In addition, the defrost timer device including the main body 1, the control unit 2, and the first, second, and third terminals 4, 5, 6, etc. is housed in the power box 7 and has a bolt or the like. The same fixing member 8 is to be mounted in the machine room of the refrigerator body 9.

In addition, after the main body 1 is accommodated in the power box 7 and mounted on the refrigerator main body 9, a first wiring is provided on the first terminal 4 protruding from the lower part of the main body 1. One end of the member 11 is connected, one end of the second wiring member 12 is connected to the second terminal 5, and one end of the third wiring member 13 is connected to the third terminal 6. Will be.

In addition, the other end of the first wiring member 11 is connected to a defrost heater that generates heat to defrost the frost generated in the evaporator, and the other end of the second wiring member 12 is connected to the bimetal disposed in the freezer compartment. The other end of the third wiring member 13 is connected to a temperature controller so as to prevent the temperature in the refrigerator from lowering below a predetermined temperature.

That is, in the conventional defrost timer device of the refrigerator, after the main body 1 is accommodated in the power box 7 and fixed to the refrigerator main body 9 by the fixing member 8, the first wiring member ( 11) the first terminal 4 and the defrost heater are connected, and the second wiring member 12 is connected to the second terminal 5 and the bimetal, and to the third wiring member 13. Thus, the third terminal 6 and the temperature controller are connected.

In the conventional defrost timer device of the conventional refrigerator, the power box (7) is required to fix the main body (1) to the refrigerator main body (9). This was degraded.

The first terminal 4 and the defrost heater are connected by the first wiring member 11, and the second terminal 5 and the bimetal are connected by the second wiring member 12. The third terminal 6 and the temperature controller are connected by the third wiring member 13, thereby increasing the assembly labor and material cost by connecting the first, second, and third wiring members 11, 12, and 13. Increasing production costs not only increased, but also decreased productivity.

Further, the first terminal 4 and the defrost heater, the second terminal 5 and the bimetal, and the third terminal 6 and the temperature controller are the first wiring member 11 and the second wiring member. (12) And when connected with the third wiring member 13, there is a problem that the incorrect wiring occurs frequently, causing a failure.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a timing means for controlling the defrost heater to operate in a machine room of the refrigerator main body without using any additional parts, thereby providing a refrigerator. It is to provide a defrosting timer device of the refrigerator that can reduce the manufacturing cost and improve the productivity at the time of manufacture and assembly of.

In order to achieve the above object, the defrost timer device of the refrigerator according to the present invention is a defrost timer device of a refrigerator that controls the defrost heater to defrost the frost generated in the evaporator, each of the defrost heater, bimetal, and temperature controller. A pipe member fixed to one side of the machine room of the refrigerator main body by receiving each connected wire, connected to each wire housed in the pipe member, and having three plug holes formed on an outer surface thereof, the outlet means disposed on the pipe member; Three plugs protrude from one side to be inserted into the outlet means, and the control unit for controlling the operation period of the defrost heater is characterized by consisting of timing means protruding.

According to the defrost timer device of the refrigerator according to the present invention, it is possible to easily mount the timing means to the refrigerator main body without the need for a separate part, so as to improve the productivity at the time of manufacturing the refrigerator, as well as in the machine room. The wires will not be exposed, which will make the machine room more clean.
