Electronic components and the like necessary for performing various controls of the ice maker 1 are built in the inside 9. Since each electronic component generates heat during the control of the ice maker 1, it is necessary to perform air cooling of these electronic components. A vent (not shown) is formed in the electrical box 19. A duct 20 is arranged behind the electrical box 19, and the duct 20 acts to control the direction of outside air taken in from the air inlet 12 and the air passing through the electrical box 19 to guide the air downward. I do. In addition, below the duct 20,
An air guide port 20A is formed. Further, a condenser 21 is disposed behind the lower air filter 18, and a fan motor 2 having a fan 22 behind the condenser 21.

To weld the guide member 15 to the upper side plate 8B, the back surface of the mounting portion 15A is brought into close contact with the side plate 8B, and the outer surface of one hanging portion 15B (the left hanging portion in FIG. 4) is attached. The lower end of each hanging portion 15B is fixed to the inner wall surface of the front panel 8A while being closely attached to the inner wall surface of the left side plate 8B. At this time, the attachment portion 15 including the extension portion 15D
Since the length L1 of A matches the distance of each side plate 8B on the long side, the guide member 15 is securely positioned at the upper end of the front panel 8A. Thus, the guide member 15
After the positioning, the mounting portion 15A and the side plate 8B are welded. Thus, the guide member 15 is fixed at the upper end of the front panel 8. The guide member 15 arranged at the lower end of the front panel 8 described above is also configured in the same manner as described above, and is also fixed by welding to the lower side plate 8B, whereby the upward fitting groove 17 is formed. Needless to say, is formed.

It is constituted by stretching. Frame member 1
In FIG. 8A, a pair of handle portions 18C are formed vertically on the vertical frame member. Each handle 18C is used when attaching and detaching the air filter 18 to and from the front panel 8.

As shown in FIG. 5, the vertical width L2 of the air filter 18 is set between the inner wall surface of the side plate 8B (upper side plate) of the front panel 8 and the bottom surface of the concave guide portion 14 of the elastic member 13. Is set to be longer than the distance L3. Specifically, the width L2 is several meters longer than the distance L3.
m, for example, about 3 mm. Such a value can be appropriately changed according to the elastic deformation characteristics of the elastic member 13. Further, as described above, the elastic member 13 is formed of an elastic material that can be elastically deformed, such as styrene foam or a hard sponge, and that exerts a pressing force based on the elastic deformation.

In the above configuration, in order to attach the air filter 18 to the front panel 8, first, the upper end of the air filter 18 is inserted into the fitting groove 16 of the guide member 15 as shown by an arrow in FIG. After fitting, the other end of the air filter 18 is fitted into the concave guide portion 14 against the elastic force of the elastic member 13. At this time, the air filter 18
Is set to be several mm larger than the distance L3 between the inner wall surface of the side plate 8B (upper side plate) and the bottom surface of the concave guide portion 14 of the elastic member 13, so that the air filter 18 is fitted. It is elastically supported between the mating groove 16 and the concave guide portion 14. When the lower air filter 18 is attached, the same procedure as described above is performed.
Upward fitting groove 17 and concave guide portion 14 of elastic member 13
And elastically supported between them.

Of the air filter 18, and the other end of the air filter 18 is elastically supported in the concave guide portion 14 of the elastic member 13.
8A etc., even if a dimensional error occurs, the error is
Can be absorbed by the elastic force. Thus, the air filter 18 can be stably and properly attached to the front panel 8. In addition, the machine room 3 is vibrated with the operation of the ice making unit 2 in the ice making machine 1 and
Also when the air filter 8 vibrates, the air filter 18 is elastically supported by the elastic member 13 at the other end, so that the vibration of the air filter 18 is absorbed by the elastic member 13 and the noise of the air filter 18 is reduced. Occurrence can be reliably prevented.

The elastic member 13 has a concave guide portion 14 for guiding the other end of the air filter 18 in the horizontal direction on the inner wall surface side of the front panel 8. The air filter 18 can be easily positioned with respect to the elastic member on the wall surface, and the air filter 18 can be easily attached and detached. Furthermore,
Originally, the elastic member 13 for preventing mutual interference of the air sucked from the air inlets 12 of the upper and lower air intake portions 10 and 11 in the front panel 8 is used as a support member of the air filter 13, so that the number of parts is reduced. And cost can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention. For example,
In the embodiment, the mounting structure of the air filter is the ice making machine 1.
However, it goes without saying that the air filter mounting structure of the present embodiment can be applied to a refrigerator other than an ice maker.

In the above-described embodiment, air is taken in from the air inlet 12 formed on the front surface of the front panel 8 and the
The ice maker 1 that exhausts air from the rear has been described as an example,
The present invention can also be applied to a device that sucks air from the front of the front panel 8 and exhausts air. Furthermore, the case where the elastic member 13 is arranged in the horizontal direction on the inner wall side of the front panel 8 has been described as an example. However, the present invention is not limited to this, and the elastic member 13 is vertically bonded and fixed on the inner wall side of the front panel 8. You may.

As described above, in the mounting structure according to the first aspect, one side end of the air filter is provided between the guide member and the elastic member disposed horizontally on the inner wall surface of the front panel. Since it is fitted to the guide member and the other end is elastically supported via an elastic member, even if a dimensional error of the air filter occurs, the error can be reduced without adversely affecting the condenser. The air filter can be absorbed by the elastic force of the elastic member, which allows the air filter to be stably and properly attached to the front panel. Also, even when the machine room is vibrated due to the operation of the refrigeration / cooling device and the air filter vibrates, the air filter is elastically supported by an elastic member at the other side end. The vibration is absorbed by the elastic member, which makes it possible to reliably prevent the generation of abnormal noise.
