Abstract

In order to provide the electrical apparatus capable of improving the handleability, the electrical apparatus of the present invention includes the fan main body portion converting electrical power into wind to output the converted wind from a front face side to an outside of the fan main body portion, the pair of side frames supporting the fan main body portion, the pair of bottom frames extending from lower ends of the side frames to a rear side, the connecting frame connecting the pair of bottom frames, and the battery retaining portion having a rechargeable battery for supplying electrical power to the fan main body portion detachably attached thereto, where the battery retaining portion is provided in the connecting frame and disposed with a space from an air inlet port at a rear face of the tan main body portion.

First claim

What is claimed is:

1. An electrical apparatus comprising:
a main body portion converting electrical power into either one of light, wind, heat, and sound to output the converted one from a front face side to an outside of the main body portion;
a pair of side frames supporting the main body portion;
a pair of bottom frames extending from lower ends of the pair of side frames to a rear side;
a connecting frame connecting the pair of bottom frames; and
a battery retaining portion having a rechargeable battery for supplying electrical power to the main body portion, the rechargeable battery being detachably attached to the battery retaining portion,
wherein the battery retaining portion is provided in the connecting frame and disposed having a space from a rear face of the main body portion, and
wherein partially-cylindrical recesses having an axial direction substantially parallel with respect to a supporting shaft of the main body portion supported by the pair of side frames are formed at upper faces of the pair of bottom frames in vicinity of the connecting frame.

2. The electrical apparatus according to claim 1 , wherein an attachment portion for the rechargeable battery is formed at a rear side of the battery retaining portion.

3. The electrical apparatus according to claim 1 , wherein, in a self-standing state of the electrical apparatus where the pair of bottom frames are grounded, a center of gravity of the rechargeable battery attached to the battery retaining portion is disposed lower than a point where the main body portion is supported by the pair of side frames.

4. The electrical apparatus according to claim 3 , wherein the main body portion is pivotally supported by each of support mechanism portions built in the pair of side frames.

5. The electrical apparatus according to claim 1 ,
wherein a face of the battery retaining portion positioned on the side of the main body portion is formed so as to be continuous from the recesses in a direction of increasing a distance from the bottom frames.

6. The electrical apparatus according to claim 1 ,
wherein a face of the battery retaining portion positioned on the side of the main body portion is formed such that a distance from the main body portion is increased from a proximal end of the battery retaining portion to a distal end thereof.

7. An electrical apparatus comprising:
a main body portion converting electrical power into either one of light, wind, heat, and sound to output the converted one from a front face side to an outside of the main body portion;
a frame portion having a pair of side frames supporting the main body portion, a pair of bottom frames extending from lower ends of the pair of side frames to a rear side, and a connecting frame connecting the pair of bottom frames; and
a battery retaining portion provided in the frame portion and having a rechargeable battery for supplying electrical power to the main body portion, the rechargeable battery being detachably attached to the battery retaining portion, wherein
the bottom frames respectively has upper surfaces each having a recess between the battery retaining portion and the main body portion so that each recess functions as a hook portion for the electrical apparatus to be hung on an external member.

8. The electrical apparatus according to claim 7 , wherein,
in a state where the bottom frames are grounded, the side frames and the battery retaining portion are configured to extend upward, and
the hook portion is configured to be located in a space formed by the main body portion, the battery retaining portion, and the frame portion.

9. The electrical apparatus according to claim 8 , wherein the hook portion is provided in a connecting portion between the bottom frame and the battery retaining portion.

10. The electrical apparatus according to claim 9 , wherein a front face side of the battery retaining portion is inclined rearward with respect to the bottom frames.

11. The electrical apparatus according to claim 8 , wherein the hook portion is provided in a connecting portion between the side frame and the bottom frame.
