Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an air conditioner for adjusting indoor temperature and humidity to desired conditions.

[Prior art] Air conditioners (hereinafter simply referred to as air conditioners) use remote control devices (hereinafter simply referred to as remote controls).
It has been proposed that the user not only be able to turn on and off the power switch of the air conditioner, but also be able to set a comfortable temperature for the user, adjust the wind direction, etc. using the air conditioner. Many of the temperature control methods are such that the user sets the temperature numerically. On the other hand, as a temperature control device inside an air conditioner, there is one shown in FIG. 5, for example.

The air conditioner 1 is provided with a first room temperature sensor 2 for detecting the temperature of the intake port to the air conditioner main body, and is capable of detecting the temperature T1 around the air conditioner main body. The remote controller is provided with a second room temperature sensor 3, which can detect the temperature T2 around the remote controller. Then, the temperature T1 signal is directly inputted, and the temperature T2 signal is inputted via the oscillator 4 and receiver 5 to an arithmetic unit 6 provided in the indoor unit. The output of the temperature control section 7 is adjusted according to the temperature difference between the temperatures T1 and T2. As a result, the temperature of the space where the user actually resides can be controlled to approach the set temperature.

[Problem to be solved by the invention] However, in conventional air conditioners, users have a desire to make the temperature in their living space comfortable, but it is troublesome to set the temperature only by temperature value. be. Furthermore, since users do not necessarily have appropriate knowledge about room temperature, they may change the room temperature more than necessary, and in some cases, it is necessary to reset the temperature midway through the use.

The present invention has been made to solve the above-mentioned problems, and saves the user's effort by automatically setting a temperature comfortable for the user in the air conditioner. The purpose is to eliminate this problem and improve the temperature control efficiency of the air conditioner.

[Means for Solving the Problems] In order to achieve this object, the air conditioner of the present invention is equipped with a remote control means, and an operating section of the remote control means is configured to control the temperature of the human body. A human body temperature detection means is provided to detect the temperature of the human body.

[Function] In the air conditioner having the above configuration, the surface temperature of the human body is detected by the human body temperature detection means provided in the remote control means, and the operation mode of the air conditioner is automatically set accordingly.

[Example 1] Hereinafter, an example embodying the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the appearance of the air conditioner of this embodiment.

The air conditioner includes an air conditioner main body 10 and a remote control transmitter 30 (hereinafter simply referred to as remote control transmitter 30). An air suction port 11 is provided on the front panel of the air conditioner main body 10. Inside the air suction port 11, there is a first tube for detecting the room temperature T.
A temperature detector 12 is provided, a first temperature detector 12
is configured to generate a detection signal corresponding to the room temperature T. As the first temperature detector 12, a thermocouple is generally often used. In addition, the air intake port 11

A detailed diagram of the remote control transmitter 30 is shown in FIG.

A holder 31 is provided on the side surface of the remote control transmitter 30. A second temperature detector 32 is provided in a part of the holder 31 . The detector 32 is configured to detect the body surface temperature T when the user holds the remote control transmitter 30 and generate a detection signal corresponding to the body surface temperature Ti. . As the second temperature detector 32, for example, a thermocouple may be used. And the temperature T

Next, an electrical configuration for controlling the temperature of the air conditioner will be described below with reference to FIG. 3.

The air conditioner body 10 is provided with a humidity detector 15 inside the air suction port 11 in addition to the first temperature detector 12 described above. The detectors 12 and 15 are configured to each send a detection signal to a control circuit 16. The control circuit 16 is configured to be able to select the operating mode of the air conditioner according to the detection signal. The operation modes include heating operation mode, cooling operation mode, ventilation operation mode, and dehumidification operation mode.

Further, a memory 21 is connected to the control circuit 16 . The memory 21 stores in advance information regarding temperature for use in the above-described temperature control.

In the air conditioner having the above configuration, a case where air conditioning is performed according to the control pattern shown in FIG. 4 will be described.

temperature'! 10° and T2° are standard temperatures determined in advance based on experimental data, etc., and are generally temperatures at which air conditioner users can spend comfortably.

First, when the user holds the holder 31 of the remote control transmitter 30 and turns on the start switch 35 to start the air conditioner, the second temperature detector 32 detects the user's body surface temperature T. At about the same time, the first temperature detector 12 detects the room temperature T. Then, the detection signal of the room temperature T and the detection signal of the user's body surface temperature T are input to the control circuit 16 . Here, the control circuit 16 controls the memory 2
Referring to the information on the temperature-related control pattern shown in FIG. 4 stored in FIG. Thereafter, while measuring the room temperature with the first temperature detector 12 at appropriate times, the temperature is adjusted so that the room temperature becomes the standard temperature T1°.

For example, when the air conditioner is started, if the temperature shown by the middle point A in FIG. 4 is T1 and T, the control circuit 16 determines that heating is necessary, and the air conditioner main body 10 operates in the heating operation mode. Then, the room temperature is T indicated by point B in the same figure.
,. When this happens, operation will be temporarily stopped.

On the other hand, when the air conditioner is started up and the temperature is T1 and T2 as indicated by the middle point C in FIG. 4, the air conditioner initially operates in the ventilation mode in order to lower the user's body temperature. The operating time is based on temperature information stored in the memory 21 in advance.

Then, T operates in the heating operation mode, and the room temperature is indicated by the middle point B in the figure. When this happens, operation will be temporarily stopped.

Furthermore, in response to the humidity signal detected by the humidity detector 15 provided inside the air suction port 11, the dehumidification mode 20 is set to a predetermined humidity determined in advance based on experimental data, etc. It is activated at the appropriate time during temperature control.

With the above configuration, it is possible to automatically set a temperature that is comfortable for the user, thereby saving the user's time and effort. Furthermore, since it is possible to prevent the room temperature from being changed too much and causing too much cooling or too much heating, the temperature control efficiency of the air conditioner can be improved.

In this embodiment, the first temperature detection means 12 is provided inside the air suction port 11 provided on the front panel of the air conditioner main body 10; It may be provided at a certain location or a part of the remote control transmitter 30.
