[0006]

Since the conventional remote control type air conditioner is constructed as described above, the temperature sensor 9 and the main body 1 are integrated, and the temperature near the main body 1 (temperature sensor 9) is maintained. To adjust the device accordingly,
The temperature distribution in the room varies depending on the shape of the room and the arrangement of objects in the room. As a result, there is a difference between the temperature measured by the temperature sensor 9 and the temperature of the actual living space (where the person is). Further, the above-mentioned difference also occurs depending on the installation location of the device, which may cause excessive cooling or heating.

The present invention has been made in order to solve the above problems, and an object of the present invention is to obtain a remote control type cooling and heating apparatus capable of controlling room temperature as a temperature at which the user actually feels it.

[0008]

According to another aspect of the present invention, there is provided a remote control type cooling and heating apparatus, in which a temperature sensor is separated from a main body and built in the remote control apparatus, and temperature information of the temperature sensor and setting information by an operation key unit are provided. And are separately transmitted as remote control signals from the transmitting unit.

According to another aspect of the present invention, there is provided a remote control type cooling and heating apparatus, in which a temperature sensor is built in the remote control apparatus, and an error signal between the temperature information of the temperature sensor and the setting information by the operation key section is transmitted as a remote control signal. It is something that is done.

[0010]

In the remote control type cooling and heating apparatus according to the invention of claim 1, the temperature information detected by the temperature sensor is received by the main body and compared with the set temperature by the operation key portion, so that the temperature and humidity closer to the sensation can be obtained. Can be controlled.

In the remote control type cooling and heating apparatus according to the second aspect of the present invention, the error signal between the temperature information of the temperature sensor and the set temperature is sent to the main body, so that the temperature and humidity can be controlled to be closer to the sensation.

【Example】

Example 1. An embodiment of the invention of claim 1 will be described below with reference to the drawings. In FIG. 1, parts having functions substantially equivalent to those in FIG. In the first embodiment, as shown in FIG.
And the T / E converter 10 is provided in the remote control device 2. An electric signal indicating temperature information obtained from the T / E converter 10 is applied to the transmitter 10. The transmitting unit 10 is configured to separately transmit the temperature information and the setting information from the microcomputer 4 as remote control signals. The temperature sensor 9 and the T / E converter 10 constitute temperature detecting means.

Next, the operation will be described. In the air conditioner configured as described above, since the temperature sensor 9 is inside the remote control device 2, the current temperature and humidity of the actual living space (where the person is) are input to the temperature sensor 9. Become. The temperature information is converted into an electric signal by the T / E converter 10 and sent to the transmitter 5, further sent to the main body 1 as a remote control signal, and received by the receiver 6.

At the same time, temperature setting information set by the operation key section 3 is sent from the microcomputer 4 to the transmitting section 5 and is received by the receiving section 6 of the main body 1 as a remote control signal.

The microcomputer 7 of the main body 1 compares the received current temperature information with the set temperature, and gives the error signal to the controller 8. The control unit 8 controls the temperature by the operation amount according to the error signal, and thereby the indoor temperature and the humidity are controlled to the set values as the sensible temperature of the place where the person is actually present.

When performing the temperature control described above, it is necessary to perform temperature feedback from the temperature sensor 9 to the microcomputer 7 on the main body 1 side, and the following three methods can be considered.

(1) When the operation key portion 3 of the remote control device 2 is operated, that is, when there is any operation such as power ON, change of set temperature, change of air volume, temperature information is transmitted together.

(2) Temperature information is automatically transmitted at regular intervals by a timer built in the microcomputer 4 of the remote control device 2.

(3) The microcomputer 4 monitors the difference between the set temperature and the current temperature, and when the difference of a certain value or more continues for a certain time or more, the difference is automatically transmitted. (4) The above (1), (2), and (3) are arbitrarily combined.

Example 2. FIG. 2 shows an embodiment of the invention of claim 2. In the second embodiment, the remote control device 2 is provided with the temperature sensor 9 and the T / E converter 10, and the temperature information obtained from the T / E converter 10 is added to the microcomputer 4 used as the comparison means. ing. The microcomputer 4 compares the temperature information with the set temperature set by the operation key unit 3, and sends the error signal to the main body 1 via the transmitting unit 5.
