The present invention relates to a refrigerator door switch device, and particularly relates to a door switch device of a refrigerator in which each interior lamp is turned on when the freezer door or the refrigerating compartment door is opened, and a fan motor is driven when all the doors are closed.

In general, the electric refrigerator is compressed by the low-temperature low-pressure gas refrigerant at a high temperature and high pressure in the compressor (2) installed on the lower side of the refrigerator main body (1) as shown in FIG. 1 and sent to the condenser (3) formed on the back, the condenser In (3), the liquid is radiated in air, liquefied, passed through a capillary tube (not shown), and depressurized. The liquid is sent to the evaporator 6 provided between the freezing chamber 4 and the refrigerating chamber 5 formed on the upper and lower sides, respectively. As the refrigerant evaporates, the circulation action to cool the surrounding air is repeatedly performed.

The air cooled in the evaporator 6 is supplied to the freezer compartment 4 and the refrigerating compartment 5 by the rotational force of the fan 7a driven by the operation of the fan motor 7 to cool the inside of the refrigerator. do.

On the other hand, the freezing compartment door 4a and the refrigerating compartment door 5a are opened and closed on the front surfaces of the freezing compartment 4 and the refrigerating compartment 5, respectively. (8) is turned on.

Conventionally, in such a refrigerator, lighting of the interior lamp is operated only when each door is opened. Accordingly, when the freezer door or the refrigerating chamber door is opened, the fan motor is continuously operated so that the cool air flows out of the refrigerator. There is a problem that the power consumption is increased while the freezing performance is lowered.

The present invention is devised to solve the problems of the prior art as described above, the object of the present invention is to stop the operation of the fan motor when the door is opened, the door of the refrigerator that can prevent cold air leakage when the door is opened It is to provide a switch device.

The door switch device of the refrigerator according to the present invention made to achieve the above object is in contact with the upper and lower buttons and the upper and lower buttons, which are installed in a carcass so as to slide the slide according to the opening and closing of the freezer compartment and the refrigerating compartment door. An upper and lower slide member having a plurality of through holes formed therein, and having a high internal light variable terminal inserted into the through hole and shorted with a fixed inner light fixed terminal installed to face the inner light, and inserted into the through hole to face the light; It consists of a fan motor variable terminal that short-circuits the fan motor fixed terminal and turns the fan motor on and off to prevent the outflow of cold air when the door is opened. It is characterized by its simple structure, reliable operation and reliability.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to FIGS. 2 and 3.

Figure 2 is a cross-sectional view showing a door switch device of the refrigerator according to the present invention, the reference numeral (10) (11) is in contact with the freezer compartment door (4a) and the refrigerator compartment door (5a), respectively, slide spring 12a (12b) The upper and lower buttons which were installed by the following are shown.

The upper and lower buttons 10 and 11 have contact protrusions 10a and 11a on the inner side thereof, and the inner and lower buttons 10 and 11 are lifted and operated by the slide operation of the upper and lower buttons 10 and 11 on the inner side thereof. The upper and lower slide members 13 and 14 are in contact with each other, and the upper and lower slide members 13 and 14 are springs 16a and 16b respectively formed on the upper and lower sides of the fixing plate 15 fixed at the center. It is shot by).

In addition, the inclined portions 13a and 14a of the upper and lower slide members 13 and 14 are always kept in contact with the contact protrusions 10a and 11a. Through-holes 17a, 17b, and 18a, 18b are formed in the inside, respectively, and the through-holes 17a, 18a are connected to a freezer compartment interior lamp 19 and a refrigerator compartment interior lamp 20, respectively. While the variable terminals 21a and 21b are penetrated and installed, fan motor variable terminals 22a and 22b connected to the fan motor 22 are penetrated in the other 17b and 18b.

On the opposite side of the high light variable terminals 21a and 21b, high light fixed terminals 23a and 23b connected to the freezing compartment high light 9 and the refrigerating compartment high light 20 are fixedly installed. Fan motor fixing terminals 24a and 24b connected to the fan motor 22 are fixed to the opposite sides of the 22a and 22b.

The door switch device of the refrigerator according to the present invention configured as described above opens any one door, for example, the freezer door 4a in a state where the freezer door 4a and the freezer door 5a are closed. By the upper button 10 is slid by the upper slide member 13, which is in the lowered state by the contact projection (10a) is raised by the repulsive force of the spring (16a) variable high internal light inserted into the through hole (17a) When the terminal 21a is in contact with the fixed lamp 23a in the high lamp, power is applied to the freezing chamber high internal copper 19 to be turned on.

Further, the fan motor variable terminal 22a inserted into the through hole 17b of the upper slide member 13 is in contact with the fan motor fixed terminal 24b as the upper slide member 13 is raised. Since the fan motor 22 is stopped and the operation of the fan motor 22 is stopped, the supply of cold air is stopped and the leakage of cold air is prevented, thereby improving the freezing performance and reducing power consumption.

On the other hand, when both the freezer compartment door 4a and the refrigerating compartment door 5a in the open state are closed, the upper and lower buttons 10 and 11 slide so that the upper slide member (10a, 11b) causes the upper slide member ( 13 is lowered and the lower slide member 14 is raised so that the inner lamps 19 and 20 are disturbed and the fan motor 22 is driven.

That is, as the upper and lower slide members 13 and 14 are lifted and lowered, the high internal light variable terminals 21a and 21b are separated from the high internal light fixed terminals 23a and 23b to stop the supply of power to the high internal light 19. 211 is extinguished, and the fan motor variable terminals 22a and 22b are connected to the fan motor fixed terminals 24a and 24b so that the fan motor 22 drives as shown in FIG. As a result, cold air is circulated in the refrigerator.

As such, the present invention enables the fan motor to operate only when both the freezer compartment and the refrigerating chamber door are closed when the door is opened, thereby preventing the leakage of cold air when the door is opened, thereby improving the freezing performance and reducing power consumption. It is possible to obtain a door switch device of a refrigerator having a reliable operation with a simple structure.
