The upper end of the bracket provided with the socket is hinged to the bottom of the installation groove so that when the bulb is replaced, the inlet side of the socket can be positioned horizontally.

The lower end of the bracket is a configuration characterized in that the engaging jaw is provided is fitted while being elastically deformed to the removable outlet.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Briefly explaining the accompanying drawings, Figure 3 shows the overall structure of the refrigerator according to the present invention, Figure 4 is an extract of the damper cover structure according to the present invention.

3, the refrigerator according to the present invention is formed so that the storage compartments 120 and 130 are partitioned therein so as to store and store food, and the refrigerator main body 110 in the enclosure filled with the heat insulating material 111. And a door 121 and 131 rotatably hinged to the refrigerator main body 110 to open and close the storage compartments 120 and 130, an evaporator 113 for generating cold air, and an evaporator 11. Refrigeration cycle components, such as a blowing fan 114 for supplying the supplied cold air.

The storage compartments 120 and 130 are divided up and down by the intermediate partition 116 to be distinguished up and down by the freezing compartment 120 and the refrigerating compartment 130. The intermediate partition 116 is configured to guide cold air return to the evaporator 113 side. The return duct 117 is formed. In addition, the shelves 140 for storing and storing food are disposed in the compartments in the storage compartments 120 and 130.

In addition, an evaporator 113 and a blowing fan 114 for forcibly blowing the cold air generated by being disposed directly above the evaporator 113 to the freezing chamber 120 and the refrigerating chamber 130 are provided at the rear of the freezing chamber 120. The cold air duct 112 is provided on the rear wall of the freezing chamber 120 and the refrigerating chamber 130, so that cold air forcedly blown by the blowing fan 114 is smoothly supplied to the freezing chamber 120 and the refrigerating chamber 130. Reference numeral "115" is a cold air discharge port for guiding the cold air coming down along the cold air duct 112 to the refrigerating chamber 130.

In addition, the cold air duct 112 formed on the rear surface of the refrigerating chamber 130 is provided with a damper 150 for controlling the amount of cold air introduced from the evaporator 113 side. The damper 150 is disposed above the cold air duct 112 of the refrigerating chamber 130, and controls the opening amount of the cold air by controlling the opening area of the cold air passage.

In addition, as illustrated in FIGS. 2 and 3, a damper cover 160 having a dial knob 161 is provided on the rear wall of the refrigerating chamber 130 to adjust the damper 150. Accordingly, by adjusting the damper 15 through the dial knob 161, it is possible to set the temperature of the refrigerating chamber 130. The damper cover 16 is fastened to the rear wall of the refrigerating chamber 130 through fastening portions 164 provided at both sides, and a plurality of cold air outlets 162 communicating with the cold air duct 112 are formed symmetrically at both sides. In addition, a damper insulation material 170 formed of an EPS material is disposed between the damper cover 160 and the rear wall of the refrigerating chamber 130 to have a predetermined thickness.

Meanwhile, the damper cover 160 is provided with an illumination device 180 for illuminating the refrigerating compartment 130 when the refrigerating compartment door 131 is opened. The lighting device 180 has a socket 182 and a light bulb 181 coupled to the socket 182 and is controlled by a door switch (not shown) which is turned on and off depending on whether the refrigerator door 131 is opened or closed. The detailed installation structure is as follows.

First, the installation groove 167 recessed in the longitudinal direction is provided at the center of the damper cover 160, the bulb cover 169 covering the front of the installation groove 167 and formed of a transparent material is detachably assembled. .

And the socket 182 is fixed to the bottom of the installation groove 167 through the bracket 187, the light bulb 181 is inserted into the socket 182 inlet is mounted. The socket 182 is placed so that the inlet is directed downward to minimize the portion protruding toward the refrigerating chamber 130, the bracket 187 is hinged 185 is coupled to the bulb 181 more easily.

That is, the upper end of the bracket 187 formed integrally with the socket 182 on the front is hinged 185 is coupled to the bottom of the installation groove 167 to enable the rotational movement in the vertical direction, the rear end of the bracket 187 An extended locking jaw 186 is provided. The bracket 187 having the locking jaw 186 is injection molded from a plastic material together with the socket 182, and the locking jaw 186 may be slightly elastically deformed.

In addition, at the bottom of the installation groove 167, the engaging jaw 186 is formed with a detachable opening 166 is fitted while being coupled to the elastic deformation. Therefore, the locking jaw 186 is elastically coupled to the removable port 166, so that the bracket 187 is firmly fixed without using a separate tool.

Next will be described the overall operation of the refrigerator and the effect of the lighting device configured as described above.

First, when the blower fan 114 is driven, a part of the cold air generated by the evaporator 113 is supplied to the freezing chamber 120, and the remaining part of the cold air is lowered along the cold air duct 112 and the cold air outlet 115 is provided. It is evenly distributed and supplied to the refrigerating chamber 130 through). At this time, the cool air coming down to the refrigerating chamber 130 through the cold air duct 112 is controlled by the damper 150.

In addition, the air that has completed the cooling operation in the freezing chamber 120 and the refrigerating chamber 130 is re-introduced to the evaporator 113 through the return duct 117, thereby continuously circulating the cold air.

Then, when the user opens the refrigerating chamber door 131 to take out the stored food, the contact of the door switch is not shown, the power is applied to the lighting device 180 thereby illuminating the refrigerating chamber 130.

On the other hand, when the overcurrent is supplied to the refrigerator or the long-term use of the bulb 181 of the lighting device 180 has reached the end of life, it should be replaced.

Replacing the bulb 181 can be easily performed in a state in which the socket 182 is rotated upward after disassembling the bulb cover 169. That is, after opening the refrigerating chamber door 131, the bulb cover 169 is disassembled from the damper cover 160. When the worker artificially pulls the socket 182, the locking jaw 186 is elastically deformed from the attachment / detachment 166 and the bracket 187 rotates upwardly about the hinge 185. As a result, the inlet of the socket 182 to which the bulb 181 is coupled is positioned in the horizontal direction.

In this state, the worker easily turns the disconnected light bulb 181 from the socket 182 and installs a new light bulb in the socket 182. Then, when the socket 182 is pushed down, the bracket 187 rotates about the hinge 185 and the locking jaw 186 is elastically deformed and coupled to the detachable opening 166 to thereby be coupled to the socket 182. The light bulb 181 is kept standing again. At this time, the socket 182 does not move without applying an artificial force by the elastic elastic force of the locking jaw 186. When the light bulb cover 169 is combined again to cover the installation groove 167, the light bulb 181 replacement operation is completed.

When the light bulb 181 is replaced by removing or assembling the light bulb 181 by replacing the light bulb 181, the inlet direction of the socket 182 is located in the horizontal direction, so that the operator can work more easily. This reduces work time and facilitates service workability.

As described in detail above, according to the lighting apparatus of the refrigerator according to the present invention, the bulb is coupled to the inlet of the socket and driven in a standing state, when the bulb replacement operation by rotating the socket in the upward direction to position the bulb in the horizontal direction Can be. Accordingly, there is an advantage that the assembly of the lighting device can be made easier in the production line as well as replacing the bulb.
