[0001]

[Industrial applications]

 The present invention relates to a remote controller with a room temperature sensor that remotely controls an air conditioner such as a cooler.

[0002]

[Prior Art]

 Generally, air conditioners such as coolers are equipped with a remote control for remote operation. In recent years, in order to bring the indoor temperature adjusted by the air conditioner closer to the sensible temperature of the user, a room temperature sensor is incorporated in the remote controller, the room temperature sensor detects the ambient temperature of the user, and the detected temperature information is detected. Is provided to control the operation of the air conditioner.

In such a remote controller, a ventilation window and a transmitter are provided side by side at one end of a flat case, and a room temperature sensor is arranged inside the ventilation window. The air outside the case then circulates around the room temperature sensor through the ventilation window, which allows the room temperature sensor to detect the temperature around the remote controller.

Normally, the remote controller is placed in the vicinity of the user, so if the operation of the air conditioner is controlled based on the temperature information around the remote controller, the user's ambient temperature will always reach a preset temperature value. Improves comfort and comfort.

[0005]

[Problems to be solved by the device]

 However, if the flat remote control is left horizontally on the floor or sofa, the ventilation window will be blocked and air will not flow well around the room temperature sensor. , It becomes difficult to properly detect the temperature around the remote control, and incorrect temperature information is sent to the air conditioner.

When the user operates the remote controller, he or she grasps the remote controller almost horizontally, and if the user holds the remote controller for a long time, the influence of the user's body temperature is reflected on the room temperature sensor in the remote controller. As a result, incorrect temperature information will be sent to the air conditioner.

When such incorrect temperature information is sent to the air conditioner, the indoor temperature is adjusted to an incorrect temperature that is far from the set temperature.

The present invention has been made in view of such a point, and an object thereof is to provide a remote controller with a room temperature sensor in which erroneous temperature information is not sent to the air conditioner. ..

[0009]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention has a ventilation window and a transmitter at one end of a remote control case, and a room temperature sensor is provided inside the ventilation window. In the case where the temperature information to be detected is sent to the air conditioner via the transmitter to control its operation, the case is provided with an attitude sensor for detecting the attitude of the case, and the attitude sensor detects the case The temperature information detected by the room temperature sensor is sent to the air conditioner only when it is detected that the attitude is upward.

[0010]

[Action]

 When the remote control is placed with the ventilation window facing upwards, the air around the remote control satisfactorily flows into the inside of the remote control through the ventilation window, so the room temperature sensor detects the true temperature around the remote control. Then, at this time, the attitude sensor detects that the remote controller is arranged with the ventilation window facing upward, and based on this detection, the temperature information detected by the room temperature sensor is sent from the transmitter to the air conditioner. ..

On the other hand, when the remote control is left on the floor or on the sofa in a state of inclining horizontally or downwardly, the ventilation window is closed and the room temperature sensor keeps the true temperature around it. It becomes difficult to detect the temperature. However, in this case, the attitude sensor detects the incompatibility of the attitude of the remote controller, and the temperature information of the room temperature sensor is not sent to the air conditioner based on this Its operation is controlled based on the information.

 An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows the external appearance of the remote controller a, where 1 is a flat case, and a plurality of operation keys 2 for temperature setting, timer setting, air volume setting, etc. and their setting status are displayed on the surface of this case 1. The liquid crystal display unit 3 is provided. A ventilation window 4 composed of a plurality of slits and a transmitter 5 for emitting infrared light for transmission are provided side by side on the edge portion of the case 1 on one end side.

An electric circuit having the configuration shown in FIG. 5 is housed inside the remote controller a, that is, 8 is a CPU, and the CPU 8 has a power source (battery) 9, a plurality of operation switches 10, ... A drive circuit 11, a remote controller room temperature sensor 12, an attitude sensor 13, an infrared LED 14 for emitting infrared light for transmission, and a drive circuit 15 thereof are connected to each other.

The remote controller room temperature sensor 12 is disposed inside the ventilation window 4, and the posture sensor 13 includes a case 18 as shown in FIG. The spherical body 19 is movably accommodated, and a pair of electrodes 20a and 20b are provided on the inner wall portion on one end side of the case 18 so as to face each other while being inclined in opposite directions. The attitude sensor 13 is provided along the longitudinal direction of the remote controller a, and when the ventilation window 4 and the transmitting unit 5 are in an attitude in which they face upward, as shown in FIG. It moves to the arrangement side of the electrodes 20a, 20b by its own weight and intervenes between the electrodes 20a and 20b, so that the electrodes 20a and 20b become conductive through the sphere 19 and the signal is sent to the CPU 8. Is becoming

FIG. 4 shows the appearance of the air conditioner A operated by the remote controller a, and 26 is its main body, and the front surface of the main body 26 receives a signal of infrared light emitted from the transmitter 5 of the remote controller a. A receiver 27 is provided. Further, inside the main body 26, a main body room temperature sensor 28 for detecting the temperature around the main body 26 is provided. Further, as shown in FIG. 6, a control circuit unit 29 for controlling the operation of the air conditioner A is incorporated inside the main body 26.

Reference numeral 30 shown in FIG. 3 is a remote control stand. The remote control stand 30 is arranged near the user, and the remote control a is inserted into the remote control stand 30 with the ventilation window 4 and the transmission section 5 facing upward. It is something to put.

When the air conditioner A is used, the remote controller a is taken out from the remote controller stand 30, the predetermined operation key 2 is operated to start the operation of the air conditioner A, and the room temperature is set. Then, insert the remote control a into the remote control stand 30 again.

The ambient air flows inside the ventilation window 4 of the remote controller a, so that the remote control room temperature sensor 12 arranged inside the ventilation window 4 sequentially detects the temperature. Here, since the remote controller a is supported in a substantially upright state, the electrodes 20a and 20b of the attitude sensor 13 are kept in the on state where they are closed, and the temperature information detected by the remote controller room temperature sensor 12 is based on this. The signal is processed by the CPU 8 and the signal is sent from the infrared LED 14 to the control circuit unit 29 through the receiving unit 27 of the air conditioner A.

Then, in the control circuit unit 29, as shown in FIG. 7, the temperature information sent from the remote controller a and the above-mentioned set temperature of the room temperature are compared, and based on this comparison, the surroundings of the remote controller a are blocked. The operation of the air conditioner A is controlled via the control circuit unit 29 so that the temperature around the user becomes the set temperature.

On the other hand, when the remote controller a is left on the floor or on a sofa in a state of inclining horizontally or downwardly, the ventilation window 4 is closed, and the remote controller room temperature sensor 12 keeps the ambient temperature sensor 12 around it. It becomes difficult to detect the temperature. However, in such a case, since the remote controller a is inclined horizontally or downward, the sphere 19 in the attitude sensor 13 is separated from the electrodes 20a and 20b as shown in FIG. The space between 20a and 20b is opened, the attitude sensor 13 is turned off, the signal is input to the CPU 8, and the signal of the temperature information of the remote controller room temperature sensor 12 emitted from the infrared LED 14 based on this is cut, The input to the receiver 27 of the air conditioner A stops.

When the input to the reception unit 27 of the air conditioner A is stopped, the signal of the temperature information of the main body room temperature sensor 28 is input to the control circuit unit 29 based on this, and this temperature information and the above-mentioned room temperature The value of the set temperature is compared, and based on this comparison, the room temperature is controlled via the control circuit unit 29 so as to reach the set temperature.

Also, when the user holds the remote controller a horizontally for a long time and the user's body temperature affects the remote controller room temperature sensor 12, the attitude sensor 13 is also turned off. It is possible to prevent incorrect temperature information from the room temperature sensor 12 from being sent to the air conditioner A.

As described above, when the attitude of the remote controller a is not suitable and the remote controller room temperature sensor 12 is in a state of detecting a temperature different from the ambient temperature of the user, the remote controller room temperature sensor 12 causes the air conditioner to operate. The transmission of the temperature information to A is stopped, and the operation of the air conditioner A is controlled based on the temperature information of the main body room temperature sensor 28. Therefore, the operation of the air conditioner A is controlled under the incorrect temperature information. Therefore, the room temperature will not be far from the set temperature.
