Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, and in particular to a power box and a fan device having the same. Background Art

[0002] A fan device can be used as a relay in a range hood to supplement its power. The power box can also be directly connected to the wind collecting box, which serves as a power source, to form a fan device. In the related art, since the power box of the fan device only has a mounting portion on one side of the wall, it can only be fixed in one way. This results in high fume removal efficiency only when the flue and the fan exhaust outlet are on the same side. If the flue and the fan exhaust outlet are not on the same side, the exhaust hose needs to make a 180° bend, which seriously reduces extraction efficiency. To address this technical problem, some manufacturers have proposed installing mounting portions on two opposing sides of the fan device's power box, selecting the mounting surface of the power box based on the user's flue direction. Existing power box mounting portions all have hanging holes on the opposing side walls of the power box, requiring only one mounting surface to be selected when securing the fan device. However, this power box also has the following problem: the mounting hole on the other side wall is open, which poses a risk of cockroaches and mice entering the power box through the open mounting hole and damaging the electrical components inside the power box.

Each of the ventilating portions b includes a cutout 13 and a cover plate 14 connected to the cutout 13. There is a gap between the edge of the cover plate 14 and the edge of the cutout 13, and the gap forms a ventilating gap of the ventilating portion b. When the cover plate 14 is removed from the cutout 13, the cutout 13 forms a hanging port for hanging the power box.

[0029] The power box of the present invention is provided with multiple side wall surfaces a, and a ventilation portion b is provided on each side wall surface a. The ventilation portion b has a ventilation function and an installation function. When the side wall surface a on one side is used as a hanging surface, the cover plate 14 of the ventilation portion b thereon needs to be removed from the incision 13 and a hanging opening is formed. The ventilation portions b on the other side wall surfaces a that are not used as hanging surfaces play a ventilation function, so that the interior of the box body 1 and the external air of the box body 1 are connected. When the power box is used on a fan device, a fan is installed in the power box, and the ventilation portion b allows external air to enter the box body 1, which can dissipate heat for the fan of the fan device.

[0030] In the power box of the present invention, the ventilation gap on the ventilation portion b on the other side wall surface a that is not used as a hanging surface is located between the edge of the cover plate 14 and the edge of the incision 13. The ventilation gap is relatively small to prevent cockroaches, mice and other small insects from entering the box body and causing damage to other electrical components installed inside the box body 1.

[0031] The power box of the present invention is provided with a plurality of ventilating portions b on the box body 1. The power box can be installed in a variety of ways. When the cover plate 14 in the cutout 13 on the side wall surface a behind the side wall surface a where the second installation opening 12 of the box body 1 is provided is removed from the cutout 13, the cutout 13 forms a hanging opening. When the hanging piece fixed on the kitchen wall is hung with the hanging opening, the second installation opening 12 faces left; when ... in front of the side wall surface a where the second installation opening 12 of the box body 1 is provided is removed from the cutout 13, the cutout 13 forms a hanging opening. When the hanging piece fixed on the kitchen wall is hung with the hanging opening, the second installation opening 12 faces left; when the cover plate 14 in the cutout 13 on the side wall surface a When the cover plate 14 in the cutout 13 is removed from the cutout 13, the cutout 13 forms a hanging opening. When the hanging piece fixed on the kitchen wall is connected to the hanging opening, the second mounting opening 12 faces the right side. When the cover plate 14 in the cutout 13 of the side wall a opposite to the side wall a of the box body 1 where the second mounting opening 12 is provided is removed from the cutout 13, the cutout 13 forms a hanging opening. When the hanging piece fixed on the kitchen wall is connected to the hanging opening, the second mounting opening 12 faces the front side. When the power box is applied to a fan device, one of the side wall surfaces a can be selected as the hanging surface according to the location of the exhaust duct in the user's space. By removing the cover plate 14 in the cutout 13 of the side wall surface a, a hanging opening can be formed and connected to the hanging piece fixed on the wall.

[0032] See also Figure 5 When the power box of the present invention is applied to a fan device, if the fan device needs to be suspended on the ceiling above the suspended ceiling, when installing the power box, the cover plate 14 in the cutout 13 on the side wall surface a on both sides of the side wall surface a of the box body 1 where the second installation opening 12 is provided is removed from the cutout 13. The box body 1 has two oppositely arranged hanging surfaces, and the box body 1 can be fixed to the ceiling through the hanging openings on the two hanging surfaces.
