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 (hereinafter referred to as an air outlet grille) provided at an air outlet of an air conditioner. Regarding air conditioners.

[Technical background of the invention and its problems]

Conventionally, air conditioners in which the angle of the outlet grille can be controlled remotely operate the outlet grille in response to an ON signal from a remote control device, and stop its operation in response to an OFF signal. In other words, the ON operation of the wind direction change operation unit provided on the remote control device, for example, pressing a push button, generates a single ON signal, and the OFF operation (release of the press) generates a single ON signal.
The outlet grill was operated and stopped by generating an OFF signal and inputting the ON and OFF signals to the air conditioner itself.

Therefore, the user turns on the wind direction change operation section, operates the outlet grille, and turns it off at the desired position.
It was operated and stopped.

However, in such air conditioners, the ON
If the air conditioner body does not receive the OFF signal for some reason even though the air outlet grill is activated by the OFF operation and the OFF signal is generated by the OFF operation, the There was a problem in that the outlet grill continued to operate, and power was wasted in the grill motor and the like that drove the outlet grill.

In addition, in order to solve this problem, from the ON operation to the OFF operation of the wind direction change operation section,
The ON signal continues to be sent, and the ON signal is stopped by the OFF operation, and the air conditioner itself is turned ON.
It is conceivable to configure the outlet grill to operate while the signal is being received, and to stop the outlet grill when the ON signal is no longer received.

However, with this method, from the ON operation
Since it is necessary to continuously transmit the ON signal until the OFF operation, the power consumption of the remote control device is high. Generally, remote control devices are powered by batteries and therefore have a small power capacity, and this increase in power consumption leads to a fatal shortening of battery life, making this method impractical.

[Purpose 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 change operation section, and a transmission 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 turned OFF.
A reception control unit that receives an operation command signal and outputs a drive signal for a predetermined period of time after receiving it, and a drive mechanism unit that continuously changes the angle of the wind direction change plate only while the drive signal is output from the reception control unit. is provided in the air conditioner main body, and 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.

A suction inlet 2, an outlet 3, a display section 4, and a light receiving section 5 are provided on the front surface of the air conditioner main body 1. 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.

Further, the remote control device 10 is provided with push button switches such as a slide switch 11 for cooling/warming, setting temperature, etc., a run/stop button 12, a wind direction change button 13, etc., and an infrared light emitting element is attached to the tip 14. .

Next, the control part of the blow-off grill operation will be explained. Wind direction change operation unit 20 provided in the remote control device 10
The ON or OFF operation (pressing or releasing the button) of the wind direction change button 13 is detected by the operation detection means 21. When an ON operation, that is, a 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 an 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,
The grill operation command signal is sent to the light receiving section 5 of the air conditioner main body.
send to 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 supplied to the intermittent signal generating means 22, and the intermittent signal generating means 22 outputs a transmission command to the transmitting means 24 every time the time-up signal is input.

Therefore, the remote control device 10 immediately issues a grill operation signal when the wind direction change operation section 20 is turned ON, and thereafter generates a grill operation command signal intermittently at regular intervals t until the OFF operation is performed. do. Further, when the OFF operation is performed, a stop signal from the operation detection means 21 is sent to the intermittent signal generation means 22.
is stopped, 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 10 using a receiving means 30 such as a phototransistor, and sends this acceptance 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 drive signal output means 32
Sends movement commands to. 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 grill motor 40 changes the angle of the outlet grill 6 substantially continuously via a link mechanism 41 that constitutes a drive mechanism section together with the grill motor 40 . At this time, since the grill motor 40 uses a geared motor with a significantly reduced speed, one cycle from horizontal to vertical to horizontal of the outlet grill 6 is approximately 10
It is about 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. Also, the second
When an operation command is input to the timer means 33 during time counting, the count contents are reset and time counting starts again from the beginning.

Therefore, in the air conditioner main body 1, after receiving the grill operation command signal and operating the outlet grill 6,
If the grill operation command signal is input within this time,
The blow-out grill operation is continued again for T time from when a new grill operation command signal is input.

Further, the time-up interval t time of the first timer means 23 and the time-up time T time of the second timer means 33 are set so that t<T.
Therefore, while the wind direction changing operation unit 20 is turned on, the grill operation command signal is intermittently output from the remote control device 10, and the blow-off grill 6 operates continuously.
When the ON operation changes to the OFF operation, the operation of the blow-off grill 6 stops after T hours from the output of the last grill operation command signal before the OFF operation.

The operation of this embodiment will be explained below. Wind direction change button 1
When 3 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 will not be output, and the blow-off grill 6 will operate for the count-up time T of the second timer 33. and then stop. (Between A and A' in Figure 3) Furthermore, if the wind direction change button 13 is continued to be pressed, a grill operation command signal is intermittently sent from the remote control device 10 to the air conditioner main body 1 every time t, and the air blower is The grill 6 continues to operate continuously. Then, when the button 13 is released from being pressed, the blow-off grill 6 stops after T time after the previous grill operation command signal (indicated by h in FIG. 3). (Between B and B' in FIG. 3) In this embodiment, there is a maximum response delay of about T hours from when the pressure on 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 described above, in this embodiment, since the intermittent operation command signal is used for the operation of the outlet grill, the power consumption of the remote control device can be reduced, and a signal is supplied to stop the operation of the outlet grill. Since this is not necessary, continuous operation of the outlet grille that is not intended by the user can be prevented.

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 upon input of this signal, the blow-off grill is operated for a time longer than the intermittent time of this signal, and the operation command is Since the outlet grille is stopped when the signal is no longer input, the power consumption of the remote control device can be reduced, and continuous operation of the outlet grille that is not intended by the user can be prevented.
