Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operating conditions of a comfort index detecting device in a wireless remote control device for an air conditioner.

2. Description of the Related Art Conventionally, in an air conditioner with a comfort index detecting device, as shown in FIG. 6, a detecting device a is built in an air conditioner body 1 having an inlet b and an outlet c, and a driving power source 2 is The same general commercial AC power supply as the power supply 2 for driving the main body of the air conditioner was used.

In addition, the comfort index detector built into the wireless remote controller has the same detector as the air conditioner main body built-in detector, and the drive power source is the battery power source 1 rather than the general commercial AC power source. This can be easily achieved by changing the temperature, but if you want to determine the effects of radiation, air flow, and temperature all at once by measuring the amount of heat required to heat a specific part and maintain it at a certain temperature A large-capacity battery power source is required for the power source.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-described conventional configuration, a power source for heating is required in order to incorporate the comfort index detection device in the wireless remote operation device. If you use a battery power source that is almost the same as the remote control device, you can choose whether to limit the number of measurements (measurement interval) or shorten the battery life and increase the frequency of battery replacement, and monitor comfort. There is a problem that the rate is lowered or the running cost for the battery is increased.

In view of the above conventional problems, the present invention has an object to suppress the consumption of the battery as much as possible.

Means for Solving the Problems In order to solve the above problems, the present invention is directed to a battery as shown in FIG. 1, a signal input means for inputting an operation signal for running / stopping, and a signal of this signal input means. And a comfort index detecting means having a heating means for detecting a comfort index, an output means for outputting a detection result signal of the comfort index detecting means to the air conditioner side at predetermined time intervals, and the comfort index. Area determination means for determining whether or not the comfort index detection mode should be executed based on the detection result by the detection means, and only when the determination result by this area determination means is the area for executing the comfort index detection mode An energization control unit that energizes the heating unit is provided.

Action In order to reduce the consumption of the power supply battery, it is necessary to reduce the heat capacity of the part that is heated to a certain temperature and keep it at a constant temperature, and at the same time shorten the time until it becomes stable. In addition to this, the temperature Ts of the specific portion to be heated and the set temperature T for keeping it at a constant temperature
When the difference from c (Ts <Tc) is large, a large amount of heating is required, and the power consumption of the power source battery also increases. In this way, when Ts <Tc and the difference is large, it is a cold and uncomfortable region. Therefore, at a temperature below a certain temperature T _A , the comfort level is not detected and a signal "cold" is immediately output to supply power. Battery consumption is reduced.

On the contrary, when the temperature and temperature above a certain temperature T _{A, which} is considered to be hot considering any possible air flow and radiation in general, immediately outputs a signal "hot" to reduce the consumption of the power supply battery. It can be reduced.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 2, reference numeral 11 denotes a wireless remote operation device (hereinafter referred to as a remote controller) that outputs various operation control signals for the air conditioner 12. Since the specific structures of the remote controller 11 and the air conditioner 12 may be well known, the description thereof will be omitted.

The remote controller 11 includes a detection circuit 11a that detects an indoor comfort index, a control circuit 11b that controls the timing of outputting the detection result of the detection circuit 11a, and a control circuit 1
Output circuit 11 for converting the signal of 1b into infrared rays and outputting it
It has c.

Further, the air conditioner 12 discriminates between the receiving circuit 12a to which the signal from the remote controller 11 is input and the signal from the receiving circuit 12a, and in addition to the operation control of the load 12c such as the compressor and the blower, the set temperature and the like. The control circuit 12b is provided for determining the mode.

Next, the configuration of the detection circuit 11a will be described with reference to FIG.

In the figure, the detection circuit 11a is a chip thermistor R.
_A current is applied to _TH to cause the thermistor R _TH to generate heat. A bridge circuit is constituted by the thermistor R _TH and the resistors R _{1 to} R _{3 so} that the thermistor R _TH has a constant temperature. A circuit is configured by the transistor Tr and the like.

When this bridge circuit is operated, the voltage V across the thermistor R _{TH in} a stable state changes depending on the ambient conditions (air flow, radiation, temperature). This change in the voltage V is in synchronization with the change in the skin temperature of the human body, and it can be used as a comfort index detection device to judge the comfort level. The detailed contents of the comfort index detecting device itself are omitted because they are not the subject matter of the present invention.

In such a wireless remote control device for an air conditioner equipped with a comfort index detecting device, as shown in FIG.
If it is detected by _TH and the air temperature is less than 15 ° C, a signal indicating that it is cold immediately is output without operating the comfort index detecting device shown in FIG.
If the temperature is above ° C, the "comfort" signal is output immediately without operating the comfort index detecting device.

The content of the comfort index mode (heating by energizing the thermistor R _TH , data (radiation, temperature, airflow) capture) control will be described below with reference to FIG. However, for convenience of explanation, it is assumed that the air conditioner is in operation.

During operation of the air conditioner, the comfort index detection circuit detects a temperature (comfort index), and if the temperature is not within the set range, the comfort index detection mode is stopped.

If the temperature is within the range, the comfort index detection mode is started. In this comfort index detection mode, the heating means, that is, the thermistor R _TH is energized and data (radiation, temperature, air flow) is taken in.

Then, when the set output time (for example, 15 minutes) elapses, the captured data are output to the air conditioner side.

The signal causes the air conditioner to operate the compressor, the blower, etc. according to the mode set corresponding to the signal, and also changes the set temperature in some cases.

The above operation is repeated to secure the indoor environment.

Therefore, the battery is energized to the heating means (thermistor R _TH ) only when the indoor environment is in the set region, so that the energization amount is suppressed when the energization amount is not necessary, and the consumption amount is suppressed.

Based on the above control, it has been confirmed by experiments that the battery consumption is suppressed by about 8% in the normal use state.

EFFECTS OF THE INVENTION As is clear from the above examples, the present invention stops unnecessary energization when the room is in a condition defined as “hot” or “cold” without detecting the comfort index. Therefore, the consumption of the battery can be suppressed, and the life of the power supply battery as the remote control device can be improved. In addition, a battery having a small capacity, that is, a small battery can be used, and the remote control device can be made light and small.
