Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling device for an electronic device such as a video tape recorder which discharges heat generated by a heat-generating component disposed inside the device body to the outside of the device.

[0002]

2. Description of the Related Art Conventionally, an electric device such as a video tape recorder is provided with a cooling device for cooling the inside of the device for radiating the heat generated by a heat-generating component arranged in the device body. For example, as shown in FIG. 3, this cooling device constitutes a part of a housing 40 of the main body of the device, and a mounting panel 50 detachably mounted on the housing 40 by a mounting member 41 such as mounting screws. It is mounted on the inner surface, and by rotating the fan with a fan motor and forcibly discharging the warmed air inside the equipment to the outside of the equipment,
The heat generated by the heat-generating component is radiated. As a mounting mechanism of the cooling device including the fan motor to the device body, the one shown in FIG. 4 is conventionally known.

The fan motor mounting mechanism shown in FIG. 4 has a fan motor unit 51 disposed inside the mounting panel 50 and a bolt 5 attached to the mounting panel 50.
2, and a plate nut 53 that cooperates with the mounting panel 50 to clamp the fan motor unit 51. Then, in the central portion of the plate nut 53, the warm air in the device corresponding to the fan portion 54 of the fan motor unit 51 is filled with the fan portion 54.
A large opening 55 is provided for feeding to.

By the way, in consideration of the safety of the fan portion 54, the mounting panel 50 is provided with a plurality of divided air holes 56 formed so as to prevent the user's fingers from entering the mounting panel 50. 50 itself functions as a finger guard. However, when the mounting panel 50 is removed by opening the mounting member 41 such as the mounting screws shown in FIG. 3 in order to perform maintenance such as cleaning or repair of the device main body, the fan motor unit 51 is not installed in the mounting panel 50. It will be exposed on the side. That is, the exposed fan motor unit 51
The plate nut 53 for mounting the
Large opening 55 for sending air to the fan section 54
The plate-shaped nut 53 cannot function as a finger guard from the inside.
Therefore, the mounting panel 50 is used for maintenance and so on.
There is a risk that fingers may enter the fan section 54 from inside. Therefore, conventionally, as shown in FIG. 4, a finger guard member 57 made of so-called lath metal is formed between the fan motor unit 51 and the plate nut 53 in a mesh shape by press working or the like in order to ensure safety during maintenance. It is arranged to intervene.

[0005]

However, inserting and arranging a separate finger guard member between the fan motor unit and the plate nut as described above makes mounting of this cooling device difficult. In particular, when assembling, it is necessary to correctly position and attach the finger gart member, resulting in a significant decrease in workability. In addition, the number of parts is increased and the cost is inevitably high.

Therefore, the present invention is intended to solve the above-mentioned conventional problems by providing a plate-like nut for assembling and fixing the fan motor unit with a function of a finger guard.

[0007]

In order to achieve the above-mentioned object, a cooling device for an electronic device according to the present invention comprises a mounting panel which constitutes a part of an outer casing and is detachable from a housing, and A fan motor unit disposed inside and a plate nut that is attached to the mounting panel by a bolt and holds the fan motor unit in cooperation with the mounting panel, and the fan motor is attached to the plate nut. An opening is provided corresponding to the fan of the unit, and a guard member is integrally provided in the opening.

[0008]

According to the present invention, since the guard member is integrally provided in the opening of the plate nut, the cooling device can be easily assembled to the mounting panel and a reliable finger guard can be formed. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing a mounting state of a cooling device in an electronic device according to the present invention to a mounting panel. First, according to the present invention, a mounting panel 1 which constitutes a part of a housing of a device body and is detachably mounted to the housing by a mounting member such as a mounting screw (not shown).
And a fan motor unit 2 disposed inside the mounting panel 1, and a plate-shaped nut mounted on the mounting panel 1 with bolts 3 and sandwiching the fan motor unit 2 in cooperation with the mounting panel 1. It is composed of 4.

On the mounting panel 1, in correspondence with the position of the fan portion 5 of the fan motor unit 2 to be mounted,
A wind hole 6 is provided. The air holes 6 are formed in a size that does not allow the user's fingers or the like to enter and that is capable of sufficiently discharging the warm air in the device. That is, in this embodiment, a plurality of arc-shaped elongated holes that are concentric and correspond to the shape of the fan portion 5 are formed. Further, bolt holes 8 are provided corresponding to the positions of the bolt insertion holes 7 formed at the four corners of the fan motor unit 2 attached to the attachment panel 1.

Next, the fan motor unit 2 is provided with a fan portion 5 composed of a fan rotated by a fan motor in the central portion thereof, so that the warmed air in the equipment cannot be discharged to the outside of the equipment. It is done like this. The bolt insertion holes 7 are provided at the four corners of the unit body 2a.
Is provided.

Next, as shown in FIG. 2, the plate nut 4 is formed as a quadrangular plate body 4a, and bolt insertion holes provided in the fan motor unit 2 at the four corners of the plate body. A screw hole 9 into which the bolt 3 is screwed is provided at the position 7. Further, the tongue piece 1 formed by bending four sides of the plate body 4a on the side opposite to the bolt screwing direction.
0 is provided.

Further, an opening 11 is provided in the central portion of the plate nut 4 corresponding to the fan portion 5 of the fan motor unit 2. And this opening 11
A guard member 12 is formed integrally therewith in order to prevent fingers of a repairer or the like from entering the fan unit 5. As shown in FIG. 2, the guard member 12 has the opening 1
1 is formed as a division piece 12a for dividing the equipment 1 into a size that does not allow the hands and fingers of a repairer or the like to enter and that is capable of sending the warmed air in the device to the fan unit 5. That is, in this embodiment, the opening 11 is divided by the division piece 12a so as to form a circular arc-shaped long hole 11a corresponding to the shape of the fan portion 5. The shape of the guide member 12 is of a size that does not allow the hands of a repairer or the like to enter as described above, and is capable of sending the warm air in the device to the fan unit 5. Any shape may be used as long as it is.

Then, the fan motor unit 2 is inserted into the mounting panel 1 formed as described above by the bolts 3 and screwed into the plate nut 4, so that the fan motor unit 2 is securely attached to the mounting panel 1. It is assembled.
At this time, since the guard member 12 for the finger guard is integrally provided on the plate-like nut 4, a separate finger guard member or the like is not required as in the conventional case, and the cooling device is assembled easily and surely. Can be attached.

[0015]

According to the present invention, since the guard member is integrally provided in the opening of the plate nut, the cooling device can be easily assembled to the mounting panel and the finger can be securely attached. Can be a guard.
Therefore, the present invention makes it extremely easy to attach the cooling device in the electronic device to the device body, and can reduce the number of parts and contribute to cost reduction.
