Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an air conditioner having a so-called personal (special) operation mode in which a temperature is controlled in a certain area (spot) around the remote control, not in the entire room, and more particularly to an air conditioner with an improved remote control.

[0002]

[Prior Art]

 Conventionally, this type of air conditioner has a normal operation mode for air-conditioning almost the entire room and, as shown in, for example, Japanese Patent Laid-Open No. 59-109738, possesses a remote controller instead of the entire room or in the vicinity thereof. A so-called personal (special) operation mode that mainly controls the air-conditioning in a certain area around the person in is configured to be manually selectable, and is illustrated by the wireless remote controller (hereinafter referred to as remote controller) 1 shown in FIG. There is no air conditioner that can be operated remotely.

The remote controller 1 has a built-in temperature sensor (not shown), and as shown in FIGS. 4 (A) and 4 (B), a temperature display section 4 for displaying a personal button 3, a set temperature, etc. on the door section 2. On the other hand, the main body 5 is provided with a drive / stop button 6, a swing button 7, a sleep button 8, and a transmission section 9 for transmitting various control signals by pressing these buttons.

As shown in, for example, FIGS. 5A and 5B, the personal button 3 is based on the temperature detected by the built-in temperature sensor of the remote controller 1 not around the room but around the individual P. This is for selecting a personal (special) operation that performs spot-like air conditioning operation such as heating or cooling, and a normal operation mode that air-conditions the entire room. When this personal button 3 is operated, the personal operation mode is selected. A transmission code composed of a special operation code for instructing +, an operation code for instructing a set temperature, an operation code for instructing, for example, an air volume, and a temperature code indicating a temperature detected by a temperature sensor built in the remote controller is sent from the transmitter 9 to the air. The information is transmitted to the main body 10 of the harmony machine, and the air conditioning is controlled so that the temperature around the individual P becomes constant at the set temperature.

After the personal operation is started, the temperature data on the remote controller 1 side is automatically transmitted every predetermined time.

[0006]

[Problems to be solved by the device]

 However, in the conventional air conditioner, when the personal operation mode is selected and the special operation code cannot be received by the air conditioner body 10 because the transmission code is relatively long, after selecting the personal operation mode, the remote controller 1 is selected. Even if the temperature data is sequentially transmitted, the air conditioner main body 10 does not perform the personal operation, the temperature data becomes useless, and the operation contents of the remote controller 1 and the air conditioner main body 10 may not match.

Therefore, the present invention has been made in consideration of such circumstances, and its purpose is to receive a special operation code indicating the operation mode when the personal (special) operation mode is selected on the air conditioner main body side. An object of the present invention is to provide an air conditioner that can reliably carry out personal operation even if it is not possible.

[0008]

[Means for Solving the Problems]

 In the present invention, when the temperature data on the remote controller 1 side is transmitted after the personal operation is selected, the special operation code for instructing the operation mode is also transmitted at the same time, and is configured as follows.

That is, the present invention receives the temperature data detected by the temperature sensor on the air conditioner main body side, and performs the air conditioning operation so as to eliminate the difference between the temperature and the set temperature, and the remote control side. In the air conditioner that has a remote controller configured to manually select the special operation mode that receives the temperature data detected by the temperature sensor of the temperature sensor and eliminates the difference between the temperature and the set temperature, The remote controller is provided with means for transmitting a signal indicating the special operation mode to the air conditioner main body side at the same time as the temperature data on the remote controller side every time a predetermined time has elapsed since the mode was selected to perform the special operation. It is characterized by being provided.

[0010]

[Action]

 When the special operation mode is manually selected, the code indicating the special operation mode is sent from the remote controller to the air conditioner main unit at the same time as the temperature data on the remote controller side, and the special temperature is detected based on the temperature detected by the remote controller. Driving is performed.

Therefore, according to the present invention, even if the code indicating the special operation mode is not received on the air conditioner main body side when the operation mode is selected, even if a predetermined time has elapsed after the special operation was selected, Since the air conditioner body receives the signal indicating the special operation mode at the same time as the temperature data on the remote control side, the special operation can be reliably performed based on the detected temperature on the remote control side.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram showing an overall configuration of an embodiment of the present invention. In the figure, an air conditioner 11 has an air conditioner body 12 and a remote controller 13 for remotely controlling the air conditioner body 12.

The remote controller 13 has a remote controller side temperature sensor 14 for detecting its ambient temperature, a temperature setting section 15 for setting the temperature and outputting a set temperature command signal for instructing the set temperature, and an entire room. A personal operation mode selection unit 16 which manually selects a normal operation mode for air conditioning and a personal (special) operation mode for air conditioning a predetermined area (spot) around the remote controller 13 and outputs a signal instructing the operation mode. Have.

The personal operation mode selection unit 16 has a personal button composed of a reversing switch. For example, pressing the button once selects the personal operation mode, pressing the button twice selects the normal operation mode, and further pressing. The personal operation mode is selected again, and this is repeated thereafter.

Further, the remote controller 13 transmits a signal processing unit 17 including a microcomputer having a control program shown in FIG. 1 built therein and a signal processed here to the air conditioner main body 12 by infrared rays or the like. It has a transmitter 18 and a display 19 for displaying the set temperature.

The signal processing unit 17 processes the temperature data detected by the remote controller side temperature sensor 14, the set temperature command signal from the temperature setting unit 15, and the operation mode command signal from the personal operation mode selection unit 16. is there.

Then, when the personal operation mode is selected by the personal operation mode selection unit 16, the signal processing unit 17 at that time is a special operation code + setting which is an operation mode command signal indicating the personal operation mode. An operation code indicating the temperature + a temperature code indicating the temperature detected by the temperature sensor 14 on the remote controller side is transmitted from the transmission unit 18 as a transmission code.

After selecting the personal operation mode, the signal processor 17 sets the personal operation mode at the same time as the temperature data around the remote controller 13 detected by the remote controller temperature sensor 14 after a predetermined time, for example, 10 minutes. The transmission unit 18 has means for transmitting the special operation code to be instructed.

On the other hand, the air conditioner main body 12 includes a reception unit 20 that receives a signal from the transmission unit 18 of the remote controller 13, a main body remote controller 21 that detects the ambient temperature of the air conditioner main body 12, a microcomputer, and the like. And a control signal processing unit 22.

When the control signal processing unit 22 receives an operation mode command signal for instructing a personal operation mode from the remote controller 13 through the receiving unit 20, the control signal processing unit 22 also detects a set temperature signal from the remote controller 13 and a detection from the remote controller side temperature sensor 14. A difference from the temperature signal is obtained, an operation command signal for eliminating the difference is given to the control unit 23, and the operation of the compressor 24 is controlled to be constant at the set temperature.

Further, the control signal processing unit 22 includes a special operation code for instructing the personal operation mode together with the temperature data from the remote controller side temperature sensor 14 every a predetermined time, for example, every 10 minutes since the personal operation mode was selected. Even when receiving, the air conditioning operation is performed so that the difference between the set temperature on the remote control 13 side and the detected temperature is obtained and the set temperature on the remote control 13 side becomes constant.

Further, when the control signal processing unit 22 receives the normal operation mode command signal from the remote controller 13 through the receiving unit 20, the difference between the temperature detected by the main body side temperature sensor 21 and the set temperature from the remote controller 13 is calculated. The control unit 23 is provided with a driving command signal for obtaining the difference and canceling the difference, and has a function of controlling the compressor 24 so as to be constant at the set temperature on the remote controller 13 side.

Next, the operation of the present embodiment will be described based on the flowchart shown in FIG. In addition, P1 to P10 in FIG. 1 indicate respective steps of the flowchart.

First, in P1, the signal processing unit 17 of the remote controller 13 determines whether or not the operation / stop button is operated. If NO, the process jumps to P4, and if YES, the operation is stopped in P2. If YES, that is, in the case of a stop operation, the stop code is transmitted from the transmission unit 18 at P3 to stop the operation of the air conditioner main body 12.

On the other hand, if NO in P2, that is, in the case of a driving operation, in P4 the ambient temperature of the remote controller 13 is read from the remote controller side temperature sensor 14, and in P5 it is determined whether or not the personal operation mode operation button has been operated. , NO returns to P1 and repeats the following.

However, when YES in P5, that is, when the personal operation mode is selected, in P6, the special operation code indicating the personal operation mode and the operation code indicating the set temperature on the remote control 13 side, for example, are selected. And the temperature code indicating the temperature data read from the remote controller side temperature sensor 14 are simultaneously transmitted from the transmitter 18 to the air conditioner main body 12 side.

After that, the timer is started at P7, the temperature detected by the temperature sensor 14 on the remote controller side is read at P8, it is judged at P9 whether a predetermined time, for example, 10 minutes has elapsed, and 10 minutes have elapsed. At this time, the special operation code indicating the personal operation mode and the temperature code indicating the temperature detected by the remote controller side temperature sensor 14 are simultaneously transmitted from the transmitter 18.

After that, the process returns to P7 again, and thereafter, every 10 minutes, the special operation code and the temperature code are simultaneously transmitted.

On the other hand, in the air conditioner main body 12, the receiving section 20 receives the special operation code, the operation code, and the temperature code from the remote controller 13, and the control signal processing section 22 detects the temperature sensor 14 on the remote controller side. The difference between the temperature and the set temperature is obtained, and the control unit 23 controls the operation of the compressor 24 so as to eliminate the difference.

For this reason, the air conditioner body 12 is personally operated at a constant set temperature based on the ambient temperature of the remote controller 13.

Then, after a lapse of a predetermined time, for example, 10 minutes, from the time when the personal operation mode is selected, the control signal processing unit 22 of the air conditioner main body 12 receives the temperature code and the special operation code through the receiving unit 20 at the same time. After confirming the operation mode, the difference between the temperature detected by the remote control side temperature sensor 14 and the set temperature is obtained again, and the operation of the compressor 24 is controlled so as to eliminate the difference.

Therefore, according to the present embodiment, even after a predetermined time has elapsed from the time when the personal operation mode was selected, the special operation code indicating the personal operation mode is transmitted at the same time as the temperature data on the remote controller 13 side. Even when the main body 12 does not receive the special operation code in the transmission code when the personal operation mode is selected, the operation mode can be confirmed even after the lapse of a predetermined time from the selection of the personal operation mode. Therefore, based on the temperature data on the remote control 13 side, the personal operation can be surely performed, and the operation inconsistency between the remote control 13 side and the air conditioner main body 12 side can be prevented.

[0034]

[Effect of the device]

 As described above, the present invention transmits a signal indicating the operation mode to the air conditioner main body side at the same time as the temperature data detected on the remote control side after a lapse of a predetermined time from the selection of the special operation. Even when the signal indicating the special operation mode is not received by the air conditioner main body when the operation mode is selected, the signal indicating the operation mode is received after the lapse of a predetermined time from the selection of the special operation mode. Therefore, the special operation can be reliably performed, and the operation inconsistency between the remote control side and the air conditioner body side can be prevented.
