Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an air conditioner in which the direction of the blowing air can be changed using a blow-off grill.

(Prior art) In general, this type of air conditioner has a blowout grille that blows out hot or cold air attached to the blowout port of the main body casing. Alternatively, the blowing direction of cold air can be adjusted.

However, these devices require the user to manually adjust the blowing direction, and air conditioners, on the other hand, are often installed high on the walls of the room.
Manual operation was extremely troublesome and difficult. For this reason, a system was developed that improved operability by making it possible to rotate the blow-off grill using a remote controller and adjust the blowing direction of hot or cold air from the remote controller.
This is shown in Publication No. 122035. In the device disclosed in this publication, a remote controller is provided with an operation knob for stopping the blow-off grill at a predetermined specific position.

(Problem to be solved by the invention) However, in the above-mentioned air conditioner, the position of the outlet grille is determined in advance in correspondence with the position of the knob, and the number of set positions of the outlet grille is only as many as the number of set positions of the knob. Therefore, it was not possible for the user to appropriately select the position of the outlet grille as desired. Furthermore, if the position of the operating knob is made to correspond to the position of the outlet grille and the position of the outlet grille can be changed continuously, the position of the outlet grille will shift with a slight shift of the operating knob. In order to set the outlet grill in the desired position, a troublesome fine adjustment operation was required.

Therefore, it is conceivable to use a wireless remote controller to adjust the angle of the outlet grill steplessly. To explain this specifically, the seventh
As shown in FIG. 8, the control signal S is continuously output by pressing the operation button 15 of the wireless remote controller 3 to position the outlet grille 2 provided at the outlet of the main body casing 1. This allows adjustments to be made from a remote location. First, the main casing 1 is the 8th
As shown in the figure, a heat exchanger 5 and a blower 7 are housed inside, a suction port 6 is provided at the upper part of the front surface, and an outlet grille 2 is provided at the outlet at the lower part of the entire surface. This blow-off grill 2 has a shaft 2a as a rotation axis, and is held rotatably within a predetermined range. Therefore, during operation of the air conditioner, the indoor air sucked in from the suction port 6 by the rotation of the blower 7 undergoes heat exchange with the heat exchanger 5, is guided to the blow-off grille 2, and is blown into the room.
At this time, by changing the position of the blow-off grille 2, the blowing direction of the wind can be changed within a range from the front to the bottom.

By continuing to press and operate the grill dedicated operation button 4 of the remote controller 3, a pattern signal S incorporating the grill operation command signal is continuously output as shown in FIG. 9, and this pattern signal S is output. During this time, the command to move the grill continues to be given to the outlet grille 2, and when the grill-dedicated operation button 4 is released, the transmission of the grille operation command signal is stopped, the outlet grille 2 is stopped, and the outlet angle is changed. The adjustment work is about to be completed. According to this, the blow-off grill can be stopped at any position desired by the operator, and the optimum wind direction desired by the operator can be obtained.

However, in such a configuration, it is necessary to continuously output the pattern signal S from the remote controller 3 while adjusting the angle of the outlet grille 2, which significantly reduces the battery life of the remote controller 3 and causes the battery to run out in a short period of time. The disadvantage is that it requires replacement.

[Structure of the device] (Means for solving the problem) This device is provided at an outlet that blows out hot or cold air, and is rotatably held so that the direction of the air blown out from the outlet can be changed. It has a blow-off grill, a drive means for continuously rotating the blow-off grill, and an operation button for operating the position of the blow-off grill, and the operation command is issued only immediately after the operation button changes to the first operation state. A remote controller that outputs a signal as a wireless signal and outputs a stop command signal as a wireless signal when the state changes to a second operation state, and a remote controller that receives a wireless signal from the remote controller and when the received wireless signal is an operation command signal. , operating the drive means continuously;
The air conditioner is provided with a control means for stopping the operation of the driving means when the received wireless signal is a stop command signal.

(Function) In the air conditioner of this invention, if the operation button of the remote controller is set to the first operation state and the operation of the outlet grill is commanded, the outlet grill operates continuously, and during this operation, the remote controller is operated. If the button is placed in the second operating state and a command is given to stop the operation of the outlet grille, the outlet grille will stop at that position, so the user can stop the outlet grille at a desired position within the movable range of the outlet grille. can.
In addition, the wireless signals output from the remote controller during the angle adjustment work of the air outlet grill include an operation command signal that is output only immediately after the operation button of the remote controller changes to the first operation state, and a wireless signal output when the operation button of the remote controller changes to the first operation state. Since only the stop command signal is output when the temperature changes, and no command signal is sent while the outlet grill is in operation, the battery life of the remote controller can be significantly extended.

(Embodiment) Hereinafter, an embodiment of the air conditioner according to the invention will be described with reference to the accompanying drawings.

Figure 1 is a control block diagram of this air conditioner.
Reference numeral 10 in the figure indicates a control circuit of the main body of the air conditioner whose operation is controlled from a remote location by a remote controller 3 serving as an infrared transmitter. The remote controller 3 has a remote control circuit 13 built into the controller casing 12, which includes a battery as a power source.
The operation is controlled by operating the 0N/0FF button 14, the grill dedicated operation button 15, and the setting change button 16, and this control signal S is pulsed and output from a transmitter 17 such as an infrared light emitting diode.

A control signal S from the remote controller 3 is input to a receiving section 18 such as a light sensor in the main casing 1 of the air conditioner. The input control signal S is sent to the signal determining section 19, and the type of the received control signal S is determined by the signal determining section 19. The signal determination section 19
Control signals generated by operating the ON/OFF button 14 or setting change button 16 are transmitted to the indoor equipment control circuit 2.
0 and the outdoor equipment control circuit 21, and both control circuits 20 and 21 input the above control signal to control the operation of the indoor fan motor drive circuit 23, the compressor 24, and the four-way valve 25. Meanwhile, the operating status of the air conditioner is displayed on the display 26.
It is now displayed in

On the other hand, the control signal PS generated by pressing the grill-dedicated operation button 15 is similarly sent to the signal determining section 19 via the receiving section 18, where the signal is processed. The signal determination section 19 is adapted to control the operation of the grill drive circuit 28. That is, when the grill dedicated operation button 15 is pressed once, the remote control control circuit 13 is activated, and a pre-coded pulse pattern signal (control signal) PS is transmitted from the transmitter 17 as shown in FIG. 3, for example. It is serially transmitted using a constant modulated wave such as 36KHz. The pattern signal PS consists of a reader code RC that determines the presence or absence of transmission, a custom code CC that distinguishes the air conditioner from other models, and data codes DC1 and DC2 that configure settings such as set temperature and air flow rate, and can be operated exclusively for grills. By pressing the button 15 once, the pattern signal PS is outputted once or multiple times. The grill operation command signal E is incorporated into the second data code DC2, for example, as shown by diagonal lines. The signal contents of each code of the pattern signal PS are represented by A, B, C, and D, and the inverted signal code for checking the contents is represented by A, B, C, and D.

Further, the pattern signal PS is transmitted from a transmitting section 17 such as an infrared light emitting diode of the remote controller 11, inputted to a receiving section 18 of the air conditioner, and processed by a signal determining section 19 serving as a CPU.
The signal determination section 19 drives the grill drive circuit 28 based on the grill operation command signal E incorporated into the pattern signal PS, and maintains the drive circuit 28 in the drive state. The air conditioner body casing structure of the outlet grille portion is similar to that shown in FIG. 8, and the outlet grille 2 is continuously rotated around the grille support shaft 2a in FIG. 8 by the drive of the grille drive circuit 28. and the blowing angle is adjusted. Then, by pressing the grill-dedicated operation button 15 next, a grill stop command signal (this signal is the same as the grill operation command signal E) is output, and the grill drive circuit 28 is stopped.

Next, the operation will be explained with reference to a flowchart in the remote control control circuit 13 of the remote controller 11 shown in FIG.

The blowing angle of hot air or cooling air blown from the air outlet of the air conditioner main body is adjusted by pressing the grill dedicated operation button 15 of the remote controller 11. Operation button 15 dedicated to this grill
With one pressing operation (ON operation), one pattern signal PS is transmitted to the transmitter 17 as shown in FIG.
Sent from. A grill operation command signal E is incorporated into this pattern signal PS, and this operation command signal E is input to the signal determination section 19 via the receiving section 18. The signal determination unit 19 inputs the grill operation command signal E to activate the grill drive circuit 28, and this operation continues regardless of whether the grill dedicated operation button 15 is released from the press (OFF operation). When the grill-only operation button 15 is once pressed and then turned on again, the grill stop command signal is incorporated into the pattern signal PS and transmitted. This grill stop command signal is sent to the receiver 1
The signal is inputted to the signal determination unit 19 via the signal processing circuit 8, and the operation of the grill drive circuit 28 is stopped. With this stoppage,
The rotation of the blowout grille 2 is stopped, and the blowout grille 2 is kept at the stopped blowout angle position.

That is, in the flowchart shown in FIG. 4, when the grill operation button 15 is pressed once, the air outlet grill 2 is operated, and the operation of the air outlet grill 2 continues until the grill operation button 15 is pressed again. It's designed not to stop. Therefore,
The user presses the grill-specific operation button 15 once to rotate the outlet grill 2, and when the user confirms that the outlet grill 2 is at the desired position during rotation, presses the grill-specific operation button 15 again. When operated, the blow-off grille 2 stops at a position desired by the user. and,
The transmission from the remote controller 11 during the angle adjustment work of the outlet grill 2 is as shown in FIG. be.

As described above, in this embodiment, the wireless signal transmitted during the angle adjustment work of the outlet grill is output only immediately after the operation button of the remote controller changes to the pressed state, which is the first operation state. There is only an operation command signal that commands the operation of the air outlet grille, and a stop command signal that stops the operation of the air outlet grille that is output when the second operation state changes to the pressed state after the pressure is released, and the air outlet grille is in operation. Since no command signal is sent to the remote controller, the battery life of the remote controller can be extended.

As another embodiment, the remote controller 11
FIG. 6 shows a flowchart in the remote control control circuit 13 with different operation modes.

In this embodiment, the pressed state of the operating button of the wireless remote controller is the first operating state, and the released state is the second operating state, and the grill operation command signal is issued only immediately after pressing the grill dedicated operating button 15. The grill stop command signal is output as a wireless signal, and when the pressing operation is released, the grill stop command signal is output as a wireless signal, and the operation on the main body side is the same as in the first embodiment.

In the flowchart shown in this figure, when the grill-dedicated operation button 15 is turned ON (pressed), a grill operation command signal E is incorporated into the pattern signal and transmitted, and based on this operation command signal E, the grill drive circuit 28 is activated and maintained in that activated state. At that time, the grill operation command signal E is pulsed once or multiple times only when the grill dedicated operation button 15 is turned on, and is transmitted in pulse form, and the grill operation command signal is not output while the grill operation button 15 is turned on thereafter. ing.

Next, when the grill dedicated operation button 15 is released, the pressed state is released (OFF operation), a grill stop command signal is received, and the drive of the grill drive circuit 28 is stopped by this stop command signal. Therefore, in order to adjust the angle of the outlet grille 2 in this embodiment, first press the grill-dedicated operation button 15, which causes the outlet grille 2 to start rotating, and then press the grill-dedicated operation button 15 until the outlet grille 2 is at the desired position. Operation button 15
If the user continues to press the button and releases the grill-dedicated operation button 15 when the outlet grille 2 reaches the desired position, the outlet grille 2 will stop at that position.

Also in this embodiment, as in the first embodiment, the transmission from the remote controller 11 during the angle adjustment work of the outlet grill 2 is limited to the grill operation button 15 after the grill operation command signal E is output for the first time. While the grill operation command signal is pressed, the pattern signal PS containing the grill operation command signal is not output, and when the grill dedicated operation button 15 is released, the pattern signal PS incorporating the grill stop command signal is only output.
Does not impair battery life.
