BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan which can be remotely controlled by a remote controller.

[0002]

2. Description of the Related Art In a fan of this type, a storage recess is formed on an upper surface of a base portion, and a remote controller is removably stored in the storage recess. Then, the remote controller is taken out from the storage recess, and the operation of the fan is remotely controlled by using the remote controller, and the fan is operated by operating the remote controller while the remote controller is stored in the storage recess. Can be used separately for controlling the operation of

A light receiving filter having a prism structure for receiving an operation signal (infrared ray) from a remote controller is provided on the base portion so that a part thereof protrudes from the upper surface of the base portion. A light receiving unit is provided below the light receiving filter and partially overlaps with the storage recess of the remote controller. Then, infrared light as an operation signal emitted from the light emitting unit of the remote controller is incident on the light receiving filter, and the infrared light is reflected on the reflection surface of the light receiving filter and is incident on the light receiving unit.

On the other hand, in the conventional fan, a long inclined portion is formed at the inner bottom of the storage recess for storing the remote controller from a substantially middle portion toward one end side. When the remote controller is housed inside, a space is created between the lower surface of the remote controller and the inner bottom surface of the storage recess that gradually increases in depth toward one end of the remote controller. Have been.

When the upper surface of one end of the remote controller is pushed downward, one end of the remote controller sinks downward through the space, and the other end of the remote controller rises upward and protrudes from the storage recess by this sink. Therefore, the remote controller can be taken out of the storage recess by picking up the protrusion by hand.

[0006]

However, if the operation signal transmitted from the light emitting unit of the remote controller is reflected in the light receiving filter, a large optical loss is caused by the reflection, and the light emitting unit of the remote controller is damaged. If the output is not set high enough reaction sensitivity cannot be obtained,
In addition, the input angle of the operation signal incident on the light-receiving filter becomes narrower, and the operation signal does not reach the light-receiving unit smoothly when operating the remote controller. Decrease. Further, if the light receiving section is arranged so as to overlap with the storage recess of the remote controller, noise may affect each other and cause a malfunction.

Further, in the conventional fan, since the inner bottom surface of the storage recess is inclined in a relatively long section extending from the intermediate portion to one end thereof, the stability of the remote controller stored in the storage recess is poor. When operating the operation buttons on the top of the remote controller with your fingertips, the remote controller swings up and down, making it difficult to operate, and when you carry a fan, the remote controller moves up and down inside the storage recess Vibration causes an unpleasant contact sound.

Therefore, a paragraph depression is formed in a part of the inner bottom surface of the storage recess, that is, a part facing one end of the remote controller, and one end of the remote controller is sunk into this depression, and the other end is raised. However, when such a means is used, when the remote controller is taken out of the storage recess, the paragraph depression is exposed and the appearance is deteriorated, and foreign matter such as dust is contained in the paragraph depression. Gradually becomes clogged, making it difficult to clean, and because it has a complicated structure in which a paragraph recess that is recessed further below it is arranged on a part of the inner bottom surface of the storage recess,
When the base portion is molded with a synthetic resin, there is a problem that the moldability deteriorates.

The present invention has been made in view of such a point, and its purpose is to improve the operability without setting the output of the light emitting section of the remote controller particularly high. It is an object of the present invention to provide a fan that can prevent malfunction due to the influence of noise and can stably store a remote controller in a storage recess with a simple structure without rattling.

[0010]

The front and rear ends of the remote controller 5 have a substantially semicircular cross section, and a light emitting element 6 as a light emitting section for emitting an operation signal (infrared ray) is provided inside the front end. A plurality of operation buttons 7 are arranged on the upper surface on the distal end side.

Between the upper surface of the base portion 1 and the front end portion of the storage recess 4, there is a step portion 3 in which the column portion 2 is higher, and a through hole 8 is formed in the wall surface of the step portion 3. At the same time, a light receiving filter 9 for receiving an infrared ray of an operation signal is attached so as to cover the through hole 8, and a light receiving element 10 as a light receiving unit is disposed inside the base portion 1 so as to face the through hole 8. Has been established.

The inner surfaces of the front and rear ends of the storage recess 4 have an arc shape corresponding to the cross-sectional shape of the front and rear ends of the remote controller 5, and the remote controller 5 is stored in the storage recess 4. In the state
The light emitting element 6 is opposed to the light receiving element 10 via the light receiving filter 9 and the through hole 8.

On the lower surface of the rear end of the remote controller 5, there is formed a flat inclined portion 11 which is inclined with respect to the axial direction of the remote controller 5. The inclined portion 11 has a lower surface of the rear end of the remote controller 5. And storage recess 4
A space H is formed between the inner surface and the inner surface. In addition, the inside of the rear end of the remote controller 5 has a relatively large space as a battery housing concave portion.

As shown in FIG. 2, an operation section 12 is provided on the upper surface of the base section 1 so as to be adjacent to the distal end side of the storage recess 4. The operation section 12 is provided with a plurality of operation buttons 13. The operation of the electric fan can be controlled separately from the remote controller 5 via the operation buttons 13.

In the electric fan constructed as described above,
When the remote controller 5 is stored in the storage recess 4, the operation buttons 7... Of the remote controller 5 are operated to input an operation signal emitted from the light emitting element 6 to the light receiving element 10 through the light receiving filter 9 to operate the electric fan. And when the remote controller 5 is taken out of the storage recess 4 and an operation signal is incident on the light receiving element 10 through the light receiving filter 9 from the far side of the base unit 1 to control the operation of the electric fan. Separately, it can be selectively used for controlling the operation of the electric fan via the operation buttons 13 of the operation unit 12 of the base unit 1.

In order to take out the remote controller 5 stored in the storage recess 4, the upper surface of the rear end of the remote controller 5 is pressed down with a fingertip. An inclined portion 11 is formed on the lower surface of the rear end of the remote controller 5, and a space H is interposed between the inclined portion 11 and the inner surface of the storage recess 4. When the upper surface is pushed downward, as shown by a chain line in FIG. 1B, the inclined portion 11 of the remote controller 5 comes into contact with the inner bottom surface of the storage recess 4, and the distal end side of the remote controller 5 rises upward and from the storage recess 4. Displace so as to protrude. Therefore, the remote controller 5 can be easily taken out by picking up the protrusion by hand.

When the remote controller 5 is stored in the storage recess 4, most of the lower surface of the remote controller 5 comes into contact with and adheres to the inner bottom surface of the storage recess 4. The state is stable, the remote controller 5 can be operated efficiently without rattling when operating the operation buttons 7... Of the remote controller 5, and the remote controller 5 can be used even when the base unit 1 is carried.

Further, the entire inner bottom surface of the storage recess 4 is flat, so that the appearance when the remote controller 5 is taken out is good, and even if foreign matter adheres to the inner bottom surface, it can be easily cleaned. Since the shape of the storage recess 4 is simple, there is an advantage that the moldability when molding the base portion 1 with a synthetic resin is good, and that the base portion 1 can be efficiently manufactured.

A light-receiving filter 9 for receiving an operation signal transmitted from the light-emitting element 6 of the remote controller 5 is provided on the step 3 of the base 1 and a side of the light-receiving filter 9 closer to the column 2 side. Light receiving element 10
Are arranged, so that the input angle of the operation signal to the light receiving filter 9 is widened, and the operation signal incident on the light receiving filter 9 is transmitted through the light receiving filter 9 to the light receiving element 10 arranged on the incident direction side. Direct and smooth input is performed, and therefore, loss due to reflection at the light receiving filter 9 is reduced, and reaction sensitivity can be increased without setting the output of the light emitting element 6 particularly high, thereby improving operability. The light receiving filter 9 does not need to have a prism structure, which facilitates the design of the light receiving filter 9.

Further, since the light receiving element 10 is arranged at a position that does not overlap with the storage recess 4 of the remote controller 5, even when the remote controller 5 is stored in the storage recess 4, both noises affect each other. Therefore, occurrence of malfunction can be prevented.

[0024]

[Effect of the invention] As described above, according to the invention,
Since the light receiving filter is provided on the step of the base portion and the light receiving portion is provided on the side of the light receiving filter near the support portion, the input angle of the operation signal to the light receiving filter is widened and the light is incident on the light receiving filter. The operation signal passes through the light-receiving filter and is directly and smoothly input to the light-receiving portion on the side of the incident direction, so that the loss due to reflection at the light-receiving filter is reduced, and the reaction sensitivity is increased without setting the output of the light-emitting portion particularly high. The operability can be improved by increasing the height. In particular, in the invention of claim 2, since the light receiving portion is arranged at a position not overlapping the storage recess of the remote controller, even when the remote controller is stored in the storage recess, both noises affect each other. Therefore, occurrence of malfunction can be prevented.

Further, in this invention, when the upper surface of one end of the remote controller housed in the storage recess is pushed downward, the other end rises upward, so that the remote controller can be easily taken out from the storage recess. When the remote controller is stored in the storage recess, it can be fixed in a stable state to prevent rattling, and when the remote controller is removed from the storage recess, the appearance is good. Even if foreign matter adheres to the inner bottom surface, it can be easily cleaned and removed, and the shape of the storage recess is simple, and the moldability when molding the base part with synthetic resin is good and efficient. There are advantages that manufacturing can be achieved.
