Description

Power supply unit of refrigerator {APPARATUS FOR POWER SUPPLY IN REFRIGERATOR}

The present invention relates to a power supply device for a refrigerator, and more particularly, to a power supply device for a refrigerator, which can fix a lead wire holder and a power cord holder using other components without installing a separate fixing bracket.

Generally, a refrigerator is a device for storing and maintaining food in a refrigerated or frozen state for a certain period of time. For this, components such as an evaporator, a condenser, and a compressor constituting a refrigeration cycle are installed, and between the inside and the outside of the refrigerator. Insulation is formed inside the foam to block the outflow of cold air and a storage space for storing food is formed inside the refrigerator.

As shown in FIG. 1, the refrigerator is divided into a freezer compartment F for freezing food and a freezer compartment R for freezing food, and a freezer compartment F at the rear side of the freezer compartment F. ) And an evaporator 1 and a freezing fan 2 for providing cold air toward the refrigerating chamber R.

In addition, doors 3 and 4 are respectively provided on the front surfaces of the freezing chamber F and the refrigerating chamber R, and the doors 3 and 4 are handled to facilitate the use of the doors 3 and 4. (5) (6) is provided.

In addition, the rear of the lower side of the refrigerating chamber (R) is provided with a compressor (7), a condenser, a machine room (M) provided with a heat dissipation fan, and each of the freezer compartment (F) and the refrigerating chamber (R) by sensing the temperature inside the refrigerator and sensing The temperature sensor 9 for the freezer compartment and the temperature sensors 10 and 11 for the 1st and 2nd refrigerator compartment which transmit a result to the microcomputer 8 are provided.

In the refrigerator configured as described above, when the detection results of the freezing compartment temperature sensor 9 and the first and second refrigerating compartment temperature sensors 10 and 11 are respectively input to the microcomputer 8, the microcomputer 8 receives the input information. The calculation determines whether the temperatures of the freezing compartment F and the refrigerating compartment R are within the set temperature range. Thereafter, the microcomputer 8 stops driving units such as the compressor 7, the heat radiating fan, and the freezing fan 2 when the temperatures of the freezing chamber F and the refrigerating chamber R are within a set temperature range. And the driving unit if the temperature of the refrigerating chamber R is not within the set temperature range.

As described above, in order to control the operation of the refrigerator by the microcomputer 8, the refrigerator is a power supply device for applying power to a driving unit such as the microcomputer 8, the compressor 7, the heat radiating fan, and the cooling fan 2. Is installed.

2 is a rear view of the refrigerator showing a power applying device of the refrigerator according to the prior art.

Referring to FIG. 2, in the power supply apparatus for a refrigerator according to the related art, a fixing bracket 21 is installed at one side of a rear surface of the refrigerator, and the fixing bracket 21 has a microcomputer 8, a compressor 7, and heat dissipation. A lead wire holder 25 for collecting and fixing lead wires 22 and 23 connected to a driving unit such as a fan and a refrigeration fan 2 and transmitting external power to the lead wires 22 and 23, respectively. A power cord holder 27 for fixing the power cord 26 is installed.

However, since the power supply device for a refrigerator according to the related art as described above requires a separate fixing bracket 21 to be installed to install the lead wire holder 25 and the power cord holder 27, the fixing bracket 21 is used as the fixing bracket 21. Due to the increase in material costs and the addition of the assembly process there is a problem that the manufacturing cost is increased and productivity is lowered.

In the above description, reference numeral 13, which is not described, denotes a defrosting water container installed on the back of the refrigerator to receive the defrosting water, and reference numerals 14a and 14b denote screws that fasten and fix the defrosting water container 13.

The object of the present invention devised in view of the problems described above, it is possible to fix the lead wire holder and the power cord holder using other components without installing a separate fixing bracket to reduce the number of parts and the number of processes An object of the present invention is to provide a power supply device for a refrigerator that reduces manufacturing costs and improves productivity.

As shown in FIG. 3, the apparatus for applying a power of the refrigerator according to the present invention is installed on the back of the refrigerator and receives the defrost water container 51 receiving the defrost water, and fastening the defrost water container 51 to the back of the refrigerator. Lead wire holder 55 which is fixed to the screws 52a, 52b, 52c to be fixed, and lead wires 53 and 54 which are installed at one side of the defrost water container 51 and connected to each electric appliance, The power cord holder 57 is installed at one side of the defrost water container 51 and is fixed to a power cord 56 for transmitting external power to each of the lead wires 53 and 54.

Here, the defrost water container 51 is formed in a form in which one side thereof is extended in comparison with the conventional one so that the lead wire holder 55 and the power cord holder 57 can be sufficiently secured.

In addition, the electronic device includes a microcomputer for controlling the operation of the refrigerator, and a driving unit such as a compressor 59, a heat radiating fan, and a cooling fan controlled by the microcomputer.

In the power supply apparatus according to the present invention configured as described above, the lead wire holder 55 and the power cord holder 57 for fixing the lead wires 53 and 54 and the power cord 56 are formed in the defrost water tank 51. The lead wire holder 55 and the power cord holder 57 can be mounted in a refrigerator without installing a separate fixing bracket by installing each side of the refrigerator.

This eliminates the need to install a separate fixing bracket for mounting the lead wire holder 55 and the power cord holder 57 to the refrigerator, thereby reducing the number of parts, thereby reducing the cost of parts and eliminating the process of assembling the fixing bracket. Thus, the number of processes is also reduced.

As described above, the apparatus for applying power to the refrigerator according to the present invention fixes the lead wire holder 55 and the power cord holder 57 by using the defrost water container 51 installed on the back of the refrigerator to receive the defrost water. Since it is possible to delete the existing fixed bracket can be reduced the number of parts and the number of processes, there is an advantage that the manufacturing cost is reduced and productivity is improved.
