2. Description of the Related Art FIG. 4 is a perspective view showing an external appearance of an example of a conventional portable fan and a wireless remote controller, and FIG. 5 is a block diagram showing a schematic configuration of the conventional portable fan. Recently, the number of portable electric fans provided with a wireless remote controller (hereinafter, abbreviated as a remote controller) for remote control has increased. However, the conventional portable electric fan A has almost all functions on the electric fan main body side, and the remote controller is treated as an accessory as it were. Therefore, as shown in FIG. 4, the operation key switches 3 and 5 (input means) for performing a series of operations and setting of the operation state are often provided in both the remote controller 1 and the fan main body 2 in an overlapping manner. . In addition, the storage circuit 7 for so-called memory start, which automatically sets the operation state at the start of the operation to the same state immediately before the previous operation stop with one touch without having to set each operation state, is provided with the electric fan main body 2.
Only prepared for. The schematic configuration of such a portable electric fan A is as shown in FIG. 5 (in the figure, the flow of signals is indicated by arrows). In FIG. 5, a remote controller 1 includes an operation key switch 3 for operating the portable fan A, and a start / stop operation and a timer setting by operating the operation key switch 3 when the portable fan A is operated. A transmission circuit 4 is provided for transmitting operation data and setting data of operation states such as air volume, swing and rhythm wind to the fan main body 2. Further, the electric fan main body 2 includes an operation key switch 5 incorporated in the main body 2, a receiving circuit 6 for receiving the data transmitted from the transmitting circuit 4 of the remote controller 1, and setting of the operating state immediately before the previous operation stop. A storage circuit 7 for storing data; a confirmation sound generation circuit 8 for generating a confirmation sound when the operation key switch 5 is operated or the data is received by the reception circuit 6; And the fan motor 9 based on the setting data stored in the storage circuit 7.
And a control circuit 10 for controlling the Therefore, when the operation key switch 3 of the remote controller 1 or the operation key switch 5 of the electric fan main body 2 is operated at the start of the operation, the operation immediately before the last operation stop is performed based on the data stored in the storage circuit 7 in the electric fan main body 2. The state could be reproduced and the memory start could be executed. Next, how the fan main body 2 operates by operating the operation key switch 3 or 5 will be described. The "operation start / stop" key switch 3a or 5a starts operation when the fan is stopped, and stops operation when pressed during operation. The air volume switching setting can be performed as follows each time the “air volume” key switch 3b or 5b is pressed. Weak → medium → strong → weak → medium → strong → ... The swinging state setting can be performed as follows each time the “bowed” key switch 3c or 5c is pressed. Swinging operation → Swinging stop → Swinging operation → Swinging stop → ... Rhythm-like state setting can be performed as follows each time the “rhythm-like” key switch 3d or 5d is pressed. Rhythm-style operation → Rhythm-style cancellation →
Rhythm-style operation → ... Here, there are three types of rhythm-style: weak rhythm style, middle rhythm style, and strong rhythm style according to the set air volume. The weak rhythm wind combines the weak tap of the fan motor 9 and the idle period to create a natural amount of wind change pattern for a certain period of time, and repeats this. The medium rhythm style combines a weak tap of the fan motor 9, a middle tap, and a rest period to create an air volume change pattern of a natural wind sensation for a predetermined time, and repeats the pattern. The strong rhythm style includes the weak tap of the fan motor 9, the middle tap, the strong tap,
Combine this with the pause period to create a natural-air-feeling air volume change pattern for a certain period of time, and repeat it. Each time the "timer" key switch 3e or 5e is pressed, a cut-off timer can be set as follows. Continuous operation → 1 hour → 2 hours → 4 hours → Continuous operation →... As an operation setting display, an LED (not shown) is displayed on the display unit of the fan body for the air volume and the cutoff timer as shown in FIG. The transmission code of the remote controller 1 indicates the following operation setting status.
Includes code consisting of bits. D1, D2, D3, D4
When D1 and D2 are 01: When weak: 10: When medium: 11: When strong D3 is 0: When heading stop 1: When heading D4 is 0: When rhythm wind is released 1: When rhythm wind: When the operation is performed, that is, when any one of the "air volume", "broom" or "rhythm style" key switch of the remote controller 1 is pressed, the operation setting state is changed as described above and a signal is transmitted. When the “start / stop” or “timer” key switch is pressed, the signal indicating the operation setting status is not changed. In this way, the setting of the operating state, the setting of the cut-off timer, and the operation of stopping the operation during the operation can be performed by either the remote controller 1 or the operation key switches 3 and 5 of the electric fan body 2.

[0003]

In the conventional portable electric fan A as described above, the electric fan is used as a storage circuit 7 for memory start for automatically setting the operation state at the start of operation to the same state immediately before the previous stop.

Embodiments of the present invention will be described below with reference to the accompanying drawings to facilitate understanding of the present invention. It should be noted that the following embodiment is an example that embodies the present invention and does not limit the technical scope of the present invention. FIG. 1 is a perspective view showing the appearance of a portable electric fan according to an embodiment of the present invention, FIG. 2 is a plan view showing the display of the portable electric fan and the appearance of a wireless remote controller, and FIG. 3 is a portable electric fan. FIG. 2 is a block diagram showing a schematic configuration of the embodiment. Also,
The same reference numerals are used for the same elements as those in the perspective view showing the external appearance of an example of the conventional portable fan and the wireless remote controller shown in FIG. 4 and the block diagram showing the schematic configuration of the conventional portable fan shown in FIG. I do. As shown in FIG. 1, a portable electric fan A ′ according to the present embodiment is a wireless remote controller (hereinafter , “ remote controller ”).
And referred to) 1 a portable fan main body (hereinafter referred to as "fan body"
(It is referred to as 2 ) . When the remote controller 1 is mounted on the electric fan main body 2, the operation key switch for performing a series of operations and setting of the operation state can be operated as if the electric fan main body 2 was also provided. An example of the operation key switch of the display unit and the remote controller 1 fan main body 2 of this shown in FIG. As with the conventional example, the functions of the remote controller 1 that can be operated with the operation key switches of the remote controller 1 include operation start / stop, air volume switching setting, off timer setting, swinging state setting, and rhythm wind state setting. There is one corresponding key switch 3a to 3e (corresponding to input means). Next, a schematic configuration of the portable electric fan A 'will be described with reference to FIG. 3 (in the figure, a signal flow is indicated by an arrow). As shown in FIG. 3, the remote controller 1 has an operation key switch 3 (corresponding to an input means) for performing an operation operation of the portable electric fan main body 2 , and a first storage indicating an operation state set by the operation key switch 3. Data M1 (Control
First memory circuit 11 formed of a volatile memory for storing equivalent) to the information (corresponding to memorize means), a portable fan main body 2
The transmission circuit 4 (transmission means) for transmitting the operation data m1 from the operation key switch 3 and the first storage data M1 from the first storage circuit 11 to the fan body 2 during the operation of the fan motor 9, specifically, the operation of the fan motor 9. ).
The first storage circuit 11 is connected to a battery (not shown) (corresponding to a backup power supply), and its stored contents are always retained.

Further, the electric fan main body 2 transmits the data m1, M1 transmitted from the transmission circuit 4 of the remote controller 1.
Receiving circuit 6 (corresponding to receiving means) , a second storage circuit 7 composed of a volatile memory for storing the first storage data M1 received by the receiving circuit 6, Confirmation sound generation circuit 8 that emits confirmation sound
And the operation data m1 received by the receiving circuit 6 and the second
Phase control circuit 10 (control means for controlling the fan motor 9 based in on the setting data M1 stored in the memory circuit 7
) . Here, the two storage data M1 and M2 of the first storage circuit 11 and the second storage circuit 7 are different in the following case. That is, when any one of the key switches 3b to 3e of "air volume", "timer", "bending" or "rhythm style" is pressed among the operation key switches 3 of the remote controller 1 during the operation stop. , Becomes invalid as the control of the fan body 2. However, as the control on the remote controller 1 side, the above-mentioned key switch operation is always effective because there is no memory of whether the operation is being performed or the operation is being stopped. For this reason, a difference in the operation setting state occurs between the fan main body 2 and the remote controller 1. Also,
When there is an obstacle between the remote controller 1 and the fan main body 2 or when the operation key switch 3 is operated without pointing the remote controller 1 in the correct direction, the operation setting state between the fan main body 2 and the remote controller 1 is set. Nokii Ichigaki occurs. In such a case, when a signal from the remote controller 1 valid on the side of the fan main body 2 is received, the control circuit 10 sets the setting data M1 of both the storage circuits 7 and 11 on the side of the fan main body 2 and the remote controller 1. , And M2, and if there is a mismatch, the setting data M2 of the second storage circuit 7 is replaced with the first storage data M1 of the remote controller 1. At this time, an operation confirmation sound having a change from the normal state is generated by the confirmation sound generation circuit 8 to notify the user that the operation setting state has changed to the normal operation setting state. Then, the fan main body 2 is set to the operation state based on the first storage data M1, and the memory start is executed. As described above, in the present embodiment, the first operation is performed by the remote controller 1 in order to perform the memory start.
And the first storage data M1 is stored here.

A battery is originally mounted on the remote controller 1, and this battery can be used for the purpose of holding the memory. In many cases, the remote controller 1 originally has a built-in one-chip microcomputer having a signal transmission function. Therefore, if the RAM of the one-chip microcomputer is used as the first storage circuit 11, the above storage can be maintained even if the power plug of the fan main body 2 is unplugged. As a result, regardless of whether the power of the fan main body 2 is turned off, when the fan motor 9 is restarted , the first storage circuit 11 of the remote controller 1 is started.
, The first storage data M1
Is transmitted to the receiving circuit 6, the memory start can be executed. Further, the first storage data M1 stored in the first storage circuit 11 is limited to the data necessary for automatically setting the operation state at the start of operation to the same state as immediately before the previous stop. For example, the air volume setting, the swing setting, the rhythm wind state setting, and the like. Therefore, the transmission data of the fan main body 2 includes the type of the operated key switch and the operation setting state. By adding such limited storage and the above-mentioned transmission data to the RAM of the one-chip microcomputer built in the remote controller 1, the cost is reduced as compared with the case where special equipment such as a nonvolatile memory is used. Upsizing can be suppressed and a compact device can be realized. By the way, in the case of a general wireless remote controller system in which signal transmission is one-way, the operation state of the fan main body 2 is changed by the remote controller 1.
Cannot be transmitted to For this reason, if the operation key switch for performing a series of operations and setting of the operation state is provided in the fan main body 2 as in the conventional example, the operation state of the remote controller 1 is stored and the fan main body 2 is operated when the operation key switch is operated. Does not match the operation state of the vehicle. Accordingly, the portable electric fan A 'of this embodiment does not include an operation key switch for performing a series of operations and setting of an operation state on the electric fan main body 2. Conventionally, there are home electric appliances (for example, a room air conditioner) other than an electric fan that store the operation setting state on the wireless remote controller side, but this is one in which the operation can be performed while checking the operation setting state at hand. It is. For example, functions such as a slide switch for setting the operation state and a liquid crystal display are provided. In this embodiment, the remote controller 1 does not have such a function, and has a simple structure including only a key switch, and can automatically set the operation state at the start of operation to the same state as immediately before the previous stop.
