Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an air conditioner, and in particular, a wireless remote controller body is equipped with a temperature sensor or a humidity sensor, which detects indoor temperature and humidity and controls the operation of the air conditioner. The present invention relates to a wireless remote control air peace machine.

[Technical background of the invention and its problems] Conventionally, when controlling the operation of an air conditioner using a wireless remote control, a temperature or humidity sensor is provided on the wireless remote control body, and the sensor detects the indoor temperature and humidity to control the air conditioner. The system controls the operation of compressors, etc. This control has the effect of controlling the space near the remote control unit to a relatively desired temperature and humidity. There was a problem that the user could not understand this, unlike other methods such as videos and videos.

In addition, in order to compensate for this problem or in case the remote controller was lost, another similar sensor was installed on the air conditioner main body to compensate for the problem, but this was done at a cost. There is a problem as it becomes a factor in the increase. Furthermore, the sensor on the remote control body side is vulnerable to the temperature and humidity environment, which poses another problem in reliability.

[Object of the Invention] The present invention has been made in consideration of the above-mentioned circumstances.When the remote control main body is hidden behind something and is not working properly,
The purpose is to provide a wireless remote control air conditioner that allows you to easily know this.

[Summary of the Invention] In order to achieve the above object, the present invention provides an air conditioner in which the wireless remote control body is equipped with at least one of temperature and humidity control, and in which the wireless remote control body is not working normally in the air conditioner body. The system is characterized by a warning means that warns the air conditioner if the wireless remote controller is hidden behind something or malfunctions and the signal cannot be received by the air conditioner itself. This system is designed to warn that the wireless remote control unit is not working properly by flashing, warning sounds from the audio warning device, etc.

[Embodiments of the Invention] A preferred embodiment of the wireless remote control air conditioner according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes an air conditioner body that is hung on a wall or the like in a room, and its operation is controlled by a wireless remote control body 2.

The wireless remote control main body 2 is provided with a temperature sensor and a humidity sensor 3, and when an operation switch (not shown) is pressed, a signal 5 such as infrared rays is transmitted from a transmitter 4, which is transmitted to the air conditioner main body 1. The receiving section 6 provided at the receiving section 6 receives the information. Although not shown in the remote control body 2, there is a timer switch for starting and stopping the exercise.
Various switches such as a temperature and humidity setting switch, a switch for selecting an operation mode such as cooling/heating/dehumidification, and an air volume changeover switch are provided, and switching signals for these switches are transmitted from the transmitter 4.

The air conditioner main body 1 is provided with a display unit 7 that displays the operating status, etc. As shown in FIG.
A room temperature indicator light 10 that works in conjunction with a temperature setting switch on the remote controller body 2 to display the difference between the temperature set by the switch and the room temperature, and a remote control use indicator light 11 that displays that the wireless remote controller body 2 is operating. and warning means for indicating that various signals from the wireless remote control main body 2 are not being received by the receiving section 6;
For example, a warning light 12 that lights up or flashes is provided. In addition to the operation of this warning light 12, a temperature or humidity sensor 1 provided in the air conditioner body 1 controls the indoor temperature and humidity.
3 detection outputs.

In the above, if the remote control main body 2 is hidden behind something while in use and the signal 5 from the transmitting section 4 cannot be received by the receiving section 6 of the air conditioner main body 1, the warning light 12 flashes to warn that fact. At the same time, the temperature or humidity is controlled by the sensor 13 on the air conditioner main body 1 side.

This will be explained in detail with reference to the flowchart of FIG. 3. When the operation switch of the remote control main body 1 is pressed, the air conditioner is turned on, that is, the air peace machine main body "1" is put into an operating state.

At this time, the indoor temperature set on the air conditioner main body 1 is Ts, the set temperature set on the remote control main body 2 is the indoor temperature detected on the TO1 remote control main body side, and the indoor temperature detected on the air conditioner main body 1 is T2. In this case, first these To,
Ts.

Detect T2. In this case, if the signal from the remote control main body 2 is normally detected by the receiving section 6 of the air conditioner I11, and the set temperature To and the detected temperature TI are detected, the wireless remote control use indicator light 11 is lit, and the air conditioner main body 1 The set temperature TS is the set temperature To of the remote control body 1, and the room t is
i! Ta is operated at the detection temperature TI of the remote control body 2, and if the room temperature Ta is lower than the set concentration TS, the compressor built into the air conditioner's refrigeration cycle is turned on and the air conditioner is operated, and the room temperature Ta is lower than the set temperature TS. If it is high, the compressor is turned off and its operation is stopped.

When the compressor is stopped, since there is a pressure difference between the discharge side and the suction side of the compressor, the compressor is restarted after a period of time (after 3 minutes in the figure) when the pressure difference decreases.

If the set temperature TO on the remote controller main body 2 and the detected temperature T1 cannot be detected by the receiver 6 of the air peace machine main body 1, the warning light 12 blinks and the set temperature is set as the set temperature TS of the air conditioner main body 1. Also, the room temperature Ta is controlled to be the temperature T2 detected by the sensor 13 on the air conditioner main body 1 side.

[Modified Embodiment] In the above-mentioned embodiment, the air conditioner main body 1 is provided with a temperature or humidity sensor 13, and when the remote control main body 2 does not work properly, an example is shown in which control is performed using the detection output of this sensor 13. , -JIIl may be performed without providing the sensor 13.

Figure 4 shows how the condenser temperature (the indoor heat exchanger side during heating and the outdoor heat exchange temperature during cooling) is detected and the condenser temperature is controlled by the air peace machine main body 1 when the remote control main body 2 does not work. The room temperature may be controlled by turning on the compressor if the chamber temperature is below the set temperature t,o, and turning it off if it is above the set temperature.

Furthermore, as shown in FIG. 5, the indoor temperature may be controlled in relation to the condenser temperature Tc and the evaporator temperature Te.

In this case, FIG. 5 shows an example of temperature control during heating operation.

FIG. 6 shows a flowchart for controlling the room temperature using the condenser temperature TC and the evaporator temperature Te as shown in FIG. 5 when the remote control main body 2 does not work normally during heating operation.

In FIG. 6, when the air conditioner is turned on, the set temperature TS and room -Ta set by the remote controller body 2 are detected, and if the TS and Ta can be detected, that is, a signal from the remote controller body 2 is received. In this case, the room temperature is controlled by turning the compressor on and off as appropriate based on the set temperature 11J[Ts on the remote controller body 2 and the detected room ITa.

If the remote control main body 2 is not working properly, the detection of the set temperature Ts and room temperature Ta is repeated, and if the number of detections is, for example, 6 or more, and TS and Ta cannot be detected, the detection is performed as explained in Fig. 5. Condenser temperature Tc and evaporator temperature Te
Control the room temperature. In this case, if the condenser temperature TC is 25°C or higher, the compressor is turned on, if it is 50°C or lower, the compressor is turned off, and if the temperature is in between, XTC-65, the compressor is turned on, and vice versa. If the amount is too low, turn off the compressor. In addition, when the compressor is turned off, the compressor is restarted after a period of time (3 minutes) for gas balance.
When the compressor is turned on, it is operated for at least 5 minutes, then returned to the initial settings, and the above-described cycle is repeated again.

Figure 7 shows an example of room restriction when the remote controller body 2 stops working when the capacity of the compressor of the air conditioner is variable. In the figure, the condenser temperature TO is detected and the The figure shows an example of controlling the current value supplied to the compressor. In this case, if the condenser temperature Tc rises, the frequency is also changed appropriately.

In the above embodiment, the warning light 12 is flashed as a warning means when the remote control main body 2 does not work properly, but it is of course possible to use a speaker, buzzer, etc. to give a warning. Further, instead of blinking the warning light 12, the remote control use indicator light 11 and the warning light 12 may be used in common, and may be configured to turn on during normal times and blink during abnormal times.

[Effects of the Invention] As is clear from the detailed description above, the present invention provides the following excellent effects.

(1) If the temperature signal from the wireless remote control unit stops midway through, or if it does not work properly due to a malfunction in the location, a warning means installed on the air conditioner unit can alert the user to this fact. can.

(2) By making it possible to control the room temperature from the air conditioner itself in addition to issuing a warning using the warning means, the temperature will not change abnormally at abnormal times.
