Description

[Detailed explanation of the idea] The present invention relates to a refrigerator equipped with a cold air circulation fan.

Conventionally, refrigerators have been provided with a fan that forcibly circulates cold air inside the refrigerator. It is configured to be installed on.

However, in this type of refrigerator, vibrations and noise generated by the operation of the drive motor, that is, the operation of the cold air circulation fan, propagate to the refrigerator main body, causing the entire refrigerator main body to vibrate and noise to leak outside the refrigerator main body. There was a problem.

The present invention has been made in view of the above circumstances, and its purpose is to provide a refrigerator that can prevent vibrations and noise caused by the operation of a cold air circulation fan from propagating to the refrigerator body.

An embodiment of the present invention will be described below with reference to the drawings.

First, in Fig. 1, which shows a part of the refrigerator, 1 is the refrigerator body, which is made of hard urethane between the outer box 2 that forms the outer wall and the inner box 3 that forms the inner wall. It is constructed by injecting and filling a foamed heat insulating material 4, and a refrigerating chamber 5 is formed inside the refrigerator main body 1.

Reference numeral 6 denotes a partition plate disposed in the refrigerator compartment 5 to form an inner box 3 and a predetermined space 7; 8 an evaporator disposed in the space 7; and 9.
are four parts formed in the inner box 3 located above the evaporator 8.

Reference numeral 10 denotes a cold air circulation fan composed of a drive motor 11 and blades 12 directly connected to the drive motor 11. The drive motor 11 is housed in the recess 9 as shown in FIG. It is attached to the drive motor attachment part 3a of the inner box 3 via screws 14, 14, and the cool air circulation fan 10 is disposed in the upper part of the space 7.

Incidentally, the drive motor mounting portion 3a of the inner box 3 means a range of the inner box 3 that includes the portion corresponding to the support 13 and the recess 9, as shown in FIG.

Now, in FIGS. 2 and 3, reference numeral 15 indicates a plurality of elongated holes, which correspond to the drive motor mounting portion 3 of the inner box 3.
It is formed so as to leave a plurality of narrow joints 16 between a and its surrounding area.

As a result, the drive motor mounting portion 3a of the inner box 3 is configured to be able to vibrate slightly in the direction of arrow A in FIG. 2 and in the opposite direction.

17 is a vibration absorbing material made of glass wool etc.
It is arranged on the back surface of the inner box 3 in correspondence with the hole 15 and the drive motor attachment part 3a before the foam insulation material 4 is injected, and when the foam insulation material 4 is injected, the vibration absorbing material 17 closes the hole 1
This prevents the undiluted solution of the foamed heat insulating material 4 from leaking from the foamed heat insulating material 5.

As is clear from the above embodiments, the present invention is such that a drive motor for a cold air circulation fan is attached to an inner box constituting an inner wall of a refrigerator body, and the drive motor mounting portion of the inner box and its surrounding area are A hole is formed so as to leave a joint between the
The refrigerator is characterized in that a vibration-absorbing material such as glass wool is provided on the back surface of the inner box in correspondence with the hole and the drive motor attachment part, and thereby the following effects can be obtained.

In other words, since the hole is formed so as to leave a joint between the drive motor mounting part of the inner box and its surroundings, the drive motor mounting part can be configured to accommodate slight vibrations, and this allows the cold air to The vibrations generated by the operation of the circulation fan can be damped, and the propagation of the damped vibrations can also be blocked by the holes.

In addition, vibration-absorbing materials such as glass wool are placed on the back of the inner box in correspondence with the holes and the drive motor mounting area, so this vibration-absorbing material can also attenuate the vibrations mentioned above. It can also absorb the noise generated.

Furthermore, since the hole is closed by the vibration absorbing material, when the storage body is constructed using a foamed heat insulating material, it is possible to prevent the stock solution of the foamed heat insulating material from leaking from the hole during injection.
