Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of an outlet of a blower such as a fan heater.

[Prior Art] Conventionally, a guide vane plate is provided at an air outlet provided in a fan device such as a fan heater to change the direction of the air blown from the air outlet, and the wind direction is changed by changing the direction of the guide vane plate. And the outlet 4
In order to make up for the decrease in wind speed from the
There is one as shown in Japanese Patent No. 617. This is a handle 10 provided on the front surface of the blower 1 as shown in FIG.
By moving up and down, the movable blade 7 provided between the blower outlet 4 and the fan 3 is moved up and down, and the opening size of the blower outlet 4 is adjusted to adjust the amount of air blown from the blower outlet 4. I have to.

[Problems to be Solved by the Invention] However, in the conventional example as described above, when the movable blade 7 is moved to adjust the ejection amount from the air outlet 4, the fan 3 and the side wall of the air passage 2 are provided. Is constant, and the air duct 2
The amount of air blown from the fan 3 to the air outlet 4 via the fan 3 is constant. Therefore, in order to suppress the amount of jet, the movable blade 7 suppresses the air blow from the fan 3. Since the blades are suppressed by the movable blades 7, there is a problem that a blast noise is generated due to the turbulence of the blast and the wind speed becomes unstable.

The present invention is intended to solve the above problems,
The purpose is to increase the wind speed as the opening size of the air outlet increases, and to reduce the air flow from the fan as the air outlet decreases. An object of the present invention is to provide a structure of an air outlet of an air blower capable of adjusting the amount of air blown from a fan according to the amount of air blown from the fan.

[Means for Solving the Problems] In order to achieve the above object, the structure of the air outlet of the air blower according to the present invention is such that the fan 3 is arranged in the air blow passage 2 in the air blower main body 1 and the air blow passage 2 is provided. An air outlet 4 is provided at the end, a movable louver 5 for adjusting the opening size of the air outlet 4 is provided on the side wall of the air passage 2 continuous with the air outlet 4, and one end of the movable louver 5 is provided between the fan 3 and the side wall. An air volume adjusting tool 7 is formed by providing a stabilizer 6 for adjusting the gap size, and the opening size of the outlet 4 can be adjusted by the movable louver 5, and the size between the fan 3 and the side wall can be adjusted by the stabilizer 6. The air flow rate adjuster 7 is rotatably arranged on a rotary shaft 8 so that the air flow rate adjuster 7 can be adjusted.

[Operation] The amount of air blown from the air outlet 4 is adjusted by rotating the air flow rate adjuster 7 by the rotating shaft 8 to move the movable louver 5 and the stabilizer 6, and the movable louver 5 moves. When the opening size of the air outlet 4 is increased, the stabilizer 6 also moves to reduce the gap size between the fan 3 and the side wall of the air passage 2 and the amount of air blown from the fan 3 through the air passage 2. It is possible to increase the amount of air blown from the air outlet 4 having a larger opening size. In addition, the movable louver 5 moves to move the air outlet 4
When the opening size of is reduced, the stabilizer 6 also moves to increase the size of the gap between the fan 3 and the side wall of the air passage 2,
It is possible to reduce the amount of air blown from the fan 3 sent through the air passage 2 and the amount of air blown from the air outlet 4 whose opening size is reduced.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

In the illustrated embodiment, a warm air blower such as a fan heater is shown as the blower. As shown in FIGS. 1 and 2, the air outlet 4 is provided at the lower front portion of the blower.
Is provided so that the air heated inside is ejected from the outlet 4 as warm air. An air blow passage 2 is provided in the air blower main body 1, and a fan 3 is arranged in the air blow passage 2 as shown in FIG. An outlet 4 is provided at the end of the air passage 2 extending laterally from below the fan 3, and the opening size of the air outlet 4 is provided on the side wall of the air passage 2 continuous with the air outlet 4. A movable louver 5 for adjusting is provided. At one end of the movable louver 5, a stabilizer 6 for adjusting the clearance between the fan 3 and the side wall is provided, and the movable louver 5 and the stabilizer 6 form an L-shaped air volume adjusting tool 7. The air flow rate adjuster 7 is rotatable by a rotary shaft 8 provided between the movable louver 5 and the stabilizer 6, and by rotating the rotary shaft 8 as a fulcrum, the opening size of the outlet 4 is adjusted by the movable louver 5. In addition, the size of the gap between the fan 3 and the side wall can be adjusted by the stabilizer 6.

Then, when the air volume from the outlet 4 is adjusted, the air volume is adjusted by rotating the air volume adjusting tool 7 with the rotating shaft 8 as a fulcrum, and the air volume is adjustable as shown by the solid line in FIG. When the louver 5 is moved upward to maintain the opening size B so that the opening size of the outlet 4 is increased, the stabilizer 6 comes close to the fan 3 as the movable louver 5 moves, and the fan 3 and the air duct 2 are moved. The size of the gap between the side wall and the side wall is A, and the size of the space between the fan 3 and the side wall of the air passage 2 is reduced. Thus, the size of the space between the fan 3 and the side wall of the air passage 2 is reduced. Then, the amount of air blown by the fan 3 through the air passage 2 becomes large, and the opening size of the air outlet 4 becomes large, and at the same time, the amount of air blown from the air outlet 4 also becomes large. Also,
When the air flow rate adjusting device 7 is rotated by the rotating shaft 8 and the movable louver 5 is lowered as shown by an imaginary line in FIG. As the louver 5 moves, the stabilizer 6 moves to the fan 3
The distance between the fan 3 and the side wall of the blower passage 2 is increased, and the size of the gap between the fan 3 and the side wall of the blower passage 2 is increased. By the rotation of the fan 3, the air is blown from between the fan 3 and the side wall of the air passage 2 and the amount of air blown from the fan 3 through the air passage 2 is reduced. The amount of air blown from the fan 3 also decreases as the amount of air blown becomes smaller, and the amount of air blown from the fan 3 is reduced by the movable louver 5.
The noise is not suppressed by the air flow, and the noise of air blow is not generated in the vicinity of the outlet 4 due to the turbulence of the air flow, and the noise can be reduced. .

In the above-described embodiment, the case where the present invention is used as a fan heater as a blower is shown, but the present invention is not limited to this, and the blower can be used for heating and cooling. You may make it use the thing.

[Advantages of the Invention] The structure of the air outlet of the air blower of the present invention is, as described above, arranged with a fan in the air blow passage in the air blower main body, and the air blow outlet is provided at the end of the air blow passage and is continuous with the air blow outlet. A movable louver that adjusts the opening size of the air outlet is provided on the side wall of the air passage, and a stabilizer that adjusts the gap size between the fan and the side wall is provided at one end of the movable louver to form an air volume adjustment tool. Since the air flow rate adjuster is rotatably arranged on the rotating shaft so that the opening size of the air outlet can be adjusted and the size between the fan and the side wall can be adjusted by the stabilizer, the air outlet can be adjusted. If the opening size of the fan is increased, the air flow from the fan can be increased through the air passage, and if the opening size of the air outlet is decreased, the air flow from the fan through the air passage can be increased. Can be less The amount of air blown from the fan can be adjusted according to the amount of air blown from the air outlet, and the wind speed of the air blown from the air outlet can be stabilized, and Even if the air volume from the outlet is low, it is possible to eliminate the turbulence of the wind and to reduce the noise.
