Abstract

PURPOSE:To reduce electric power consumption and eliminate a signal to stop the operation of discharge grille by providing a driving mechanism unit which changes the angle of an airflow deflecting plate continuously only during driving signal outputting and making the transmitting time interval of operation commanding signal shorter than the outputting time of driving signal. CONSTITUTION:In case the time of pushing of an airflow changing button 13 is shorter than the time-up time (t) of first timer means, the next grille operation commanding signal is not output and the discharge grille 6 operates only during the count-up time T of second timer, then stops. On the other hand, in case pushing of the airflow deflecting button 13 continues, the grille operation commanding signal is sent intermittently at a time interval (t) from a remote control unit 10 to the main body 1 of the air-conditioning machine and the discharge grille 6 continues the operation thereof. When the button 13 is released, the operation of the discharge grille 6 stops time period T after outputting the grille operation commanding signal is output. Accordingly, since intermittent operation commanding signal is employed, electric power consumption of the remote control unit is reduced and, further, the discharge grille operation stopping signal becomes unnecessary.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an air conditioner, and in particular to a method that enables remote control of the angle of a wind direction changing plate C (hereinafter referred to as an outlet grille) provided at an outlet of an air conditioner. Regarding air conditioners.

[Technical background of the invention and its problems]

Conventionally, in air conditioners in which the angle of the outlet grille can be controlled remotely, the outlet grille is operated by an ON signal from the remote control device and stopped by an OFF signal. A single ON signal is generated by the ON operation of the provided air direction change operation unit, for example, by pressing a push button, and a single OFF signal is generated by the OFF operation (release of suppression), and these ON and OFF signals are transmitted to the air conditioner. The outlet grill was operated and stopped by inputting f to the main unit.

Therefore, the user turns on the wind direction changing operation section to operate the blow-off grille, and then turns it off at a desired position to stop it.

However, in such an air conditioner, after the outlet grill is operated by the ON operation, it is turned OFF by the OFF operation.
Even though the signal was generated, for some reason this O
If the FF signal is not received by the air conditioner, the outlet grill will continue to operate despite the user's OFF operation, and power will be wasted in the grill motor that drives the outlet grill. There was a problem that

In addition, in order to solve this problem, it is necessary to turn on the wind direction change operation section.
The ON signal is continuously sent from the operation to the OFF operation, and the ON signal is stopped when the OFF operation is performed.The air conditioner operates the outlet grill while receiving the ON signal, and when the ON signal is received. It is conceivable to configure the outlet grille to be stopped when it is no longer being used.

However, with this method, it is necessary to transmit the ON signal continuously from the ON operation to the OFF operation.
There was a drawback that the power consumption of the remote control device was large. In general, remote control devices use batteries as a power source, so their power capacity is small, and this increase in power consumption would lead to a fatal shortening of battery life (this made this method impractical.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner in which the power consumption of a remote control device is small and there is no need to supply a signal to stop the outlet grill.

[Summary of the invention]

The present invention provides a remote control device with a wind direction changing operation section, and a transmitting section that intermittently transmits an operation command signal when the wind direction change operation section is turned on, and stops transmitting the operation command signal when the wind direction change operation section is turned off. A reception control unit that receives an operation command signal and outputs a drive signal for a predetermined time after receiving it, and a drive mechanism that continuously changes the angle of the wind direction change plate only while the drive signal is output from the reception control unit. This is an air conditioner in which the transmission time interval of the operation command signal is shorter than the output time of the drive signal.

[Embodiments of the invention]

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. The front surface of the air conditioner main body l is provided with an inlet 2, an outlet 3, a display section 4, and a light receiving section 5. . A blowout grill 6 is attached to the blowout port 3 and is pivotally supported at both ends of the blowout port 3. This blow-off grill 6 is connected to a grill motor 40 via a link mechanism 7, and as the grill motor 40 rotates, it continuously rotates through an angular width of about 90 degrees from horizontal to vertical.

That is, the blowout grille 6 moves from horizontal to vertical and from vertical to horizontal.

In addition, an infrared light emitting element is attached to the tip portion 14.

Next, the control part of the blow-off grill operation will be explained. Far pressure,
(press release) is detected by the operation detection means 21. And O
When the N operation, that is, the pressed state of the wind direction change button 13 is detected, the operation detection means 21 sends an operation signal to the intermittent signal generation means 22, and when the OFF operation is detected, it sends a stop signal. When the operation signal is input, the intermittent signal generating means 22 immediately sends a transmission command to the transmitting means 24 and also sends a timer start signal to the first timer means 23. When the transmission command is input, the transmission means 24 drives the infrared light emitting element and sends the grill operation command signal to the light receiving section 5 of the air conditioner main body. Further, the first timer means 23 is set in advance to output a time-up signal every t time after receiving the timer start signal. This time-up signal is generated by the intermittent signal generating means 2.
The intermittent signal generating means 22 outputs a transmission command to the transmitting means 24 every time the time-up signal is input.

Therefore, in the remote control device 10, the wind direction change operation unit 20 is
When N is operated, a grill operation signal is immediately issued, and then O is operated.
A grill operation command signal is generated intermittently at regular intervals until the FF operation is performed. Further, when the OFF operation is performed, the intermittent signal generating means 22 is stopped by a stop signal from the operation detecting means 21, and the first timer means 23 is reset and stopped.

Next, the air conditioner main body 1 receives a grill operation command signal from the remote control device IO using a receiving means 30 such as a phototransistor, and this receiving means sends the signal to a signal analyzing means 31. The signal analysis means 31 performs check analysis of the signal sent from the remote control device 10. If the signal sent is a grill operation command signal, the operation command is sent to the drive signal output means 32. When the drive signal output means 32 receives this operation command, it starts the operation of the second timer means 33 and sends a drive signal to the grill motor 40. The angle of the outlet grille 6 is changed substantially continuously via the grille motor 40 and a link mechanism 41 which together with the grille motor 40 constitutes a drive mechanism. At this time, since the grill motor 40 uses a geared motor with a significantly reduced speed, one cycle of the blow-out grill 6 from horizontal to vertical to horizontal takes about 10 seconds.

On the other hand, the second timer means 33 starts time counting upon receiving the operation command, and sends a time-up output to the drive signal output means 32 after a certain period of time T.

The drive signal output means 32 stops outputting the drive signal in response to this time-up signal. Further, when the second timer means 33 receives an operation command during time counting, the counting contents are reset and the time counting starts again from the beginning.

Therefore, in the air conditioner body 1, if a grill operation command signal is input within 7 hours after receiving the grill operation command signal and operating the outlet grill 6, a new grill operation command signal is input. From time to time, the second timer means 3
The time-up time T time in step 3 is set to 5 so that t<T. Therefore, while the wind direction change operation section 20 is being turned on, the grill operation command signal is intermittently output from the remote control device 10, and the air blowing Grill 6 operates continuously.

Then, when the ON operation changes to the OFF operation, the O
T from the output of the last grill operation command signal before FF operation
After a period of time, the operation of the blow-off grill 6 is stopped.

The operation of this embodiment will be explained below. When the wind direction change button 13 is pressed, it is determined to be an ON operation, and a grill operation command signal is output from the remote control device 10.

The air conditioner main body 1 receives this grill operation command signal and operates the outlet grill 6.

At this time, if the pressing of the wind direction change button 13 is shorter than the time-up time t of the first timer means 23, the next grill operation command signal is not output, and the blow-off grill 6 is activated by the second timer means 33.
It operates for the count up time T and then stops. (Between A and A' in Figure 3) 10 is sent to the air conditioner main body 1,
The blowout grille 6 continues to operate continuously. And button 13
When the suppression is released, the blow-off grill 6 will stop one hour after the previous grill operation command signal (indicated by h in FIG. 3). (Between B and B' in FIG. 3) In this embodiment, a maximum response delay of approximately T time occurs from when the suppression of the wind direction change button 13 is released until the blow-off grille 6 stops. However, since the rotation speed of the grill motor is sufficiently low, by setting the times t and T to appropriate values, it is possible to keep the rotation angle of the grill due to the response delay within an allowable range.

As mentioned above, in this embodiment, the power consumption of the remote control device can be reduced because the intermittent operation command signal is used for the operation of the outlet grill, and the signal is also used to stop the operation of the outlet grill. Since there is no need to supply the air, it is possible to prevent the continuous operation of the air outlet grille as intended by the user.

Further, in this embodiment, since the blow-off grill is operated and stopped by pressing and releasing the push button, only one push button is required as the switch for operating the blow-off grill.

〔Effect of the invention〕

As described above, according to the present invention, an intermittent operation command signal is output from a remote control device, and by inputting this signal,
The outlet grill is operated only for a time longer than the intermittent time of this signal, and the outlet grill is stopped when the operation command signal is no longer input, thereby reducing the power consumption of the remote control device and preventing unintentional air blowing by the user. Continuous operation of the grill can be prevented.
