Description

The fixing member of the fan motor of the refrigerator {THE MEMBER FOR FIXING A FAN MOTOR OF REFRIGERATOR}

The present invention relates to a fan motor fixing member of a refrigerator, and more particularly, to a fan motor fixing member of a refrigerator having a structure in which a bell mouse and a first motor cover can be injection molded integrally and can be injection molded by a simple operation. will be.

In general, a refrigerator includes a freezer compartment and a refrigerating compartment for storing items as a predetermined space inside the cabinet, and cooling devices are installed in a machine room provided at the rear of the cabinet to keep the freezer compartment and the refrigerating compartment at a low temperature. The refrigerator's cooling apparatuses include a compressor for compressing a gas refrigerant into a high temperature and high pressure gas refrigerant, a condenser for cooling, condensing and liquefying the high temperature and high pressure gas refrigerant transferred from the compressor by external air, and a liquid from the condenser. A capillary tube or expansion valve for depressurizing the refrigerant and an evaporator for absorbing and cooling the surrounding heat while the decompressed refrigerant from the capillary is evaporated. The refrigerant passes heat inside the refrigerator as the refrigerant passes through the cooling device. To emit.

At this time, the refrigerant generated in the evaporator is blown into the freezer compartment by a cooling fan installed in the freezer compartment, and the cold air is again transferred into the refrigerating compartment and used to refrigerate items stored in the refrigerating compartment. Moreover, the cooling fan is rotated by a fan motor which is driven simultaneously when the compressor and the evaporator are operated, and the fan motor is fixed to the upper wall of the refrigerator for absorbing vibration.

Meanwhile, a cooling fan fixing member is typically used to fix the fan motor to the upper wall of the refrigerator. Looking at the configuration of the conventional cooling fan fixing member with reference to FIG. 1, the fixing member 10 is a fan motor 60 (FIG. 2) the first motor cover 30 and the second motor cover 40 provided at the front and rear sides of the fan motor to surround the first motor cover 30 and a predetermined distance apart from the first motor cover 30 (BELL MOUTH, 20) ). In addition, the second motor cover 40 is fixed to the inside of the refrigerator located inside the rear of the refrigerator and fixed to the first motor cover 30, thereby being embedded in the accommodation space formed by the first motor cover and the second motor cover. Fan motor 60 (FIG. 2) is fixedly supported in front and rear by the covers. In this case, the bell mouse 20 is provided to guide the air volume of the cooling fan into the air, and is generally provided in a disc shape, but a through hole is formed therein, and the cooling fan 61 is disposed in the through hole. Furthermore, the fixing ribs 50 are formed to face each other on both sides of the bell mouse so as to be easily fixed to the first motor cover and to extend rearward, and fastening holes 51 are formed at the ends of the fixing ribs. This is provided. On the other hand, when the end of the fixed rib is mounted on the first motor cover when the motor rotates to generate a vibration, the vibration of the bell mouse and the first motor cover by the vibration of the first motor cover Both sides are provided with a reinforcing member 31 to which the fixing rib is inserted and fixed. Therefore, the reinforcing rib, the first motor cover, and the second motor cover are fixed to each other by fastening a bolt to the fastening hole 51 in a state in which the rear end of the fixing rib is fixed to the reinforcing member.

FIG. 2 illustrates a first motor cover, and a vibration absorber 32 is provided between the first motor cover 30 and the second motor cover to absorb vibration generated as the motor is driven and the cooling fan rotates. do.

In addition, the first motor cover has a through hole 33 formed to penetrate the rotating shaft of the motor in the front center portion, and extends horizontally on both sides so that the fastening bolt inserted into the fastening hole of the fixing rib is fastened to the fastening piece 37. And fastening holes 37 are provided in the fastening pieces. Furthermore, one side of the first motor cover has a wire insertion groove 34 is formed so that the wire connected to the motor passes and provided with a wire fixing piece 35 for fixing the wire. As described above, the fixing member of the fan motor of the refrigerator is injection molded to facilitate manufacturing, and this injection molding operation prepares the mold in the same shape as the fixing member and injects the plastic injection liquid into the mold, thereby manufacturing the fixing member. For this operation, the structure of the fastening member needs to be simplified and divided into a plurality of parts.

However, if the fixing member is divided into bell mouse, first motor cover, and second motor cover as described above, and then assembled separately, the work time for assembling each part is increased, and the mold is separately installed. Since there was a problem that the manufacturing cost is rising.

Accordingly, the present invention provides a fan motor fixing member of a refrigerator having a configuration capable of shortening manufacturing cost and assembly time by dividing and fixing the fixing member into fewer parts to solve the problems as described above. That is the purpose.
