Abstract

PURPOSE:To hold a room in a more comfortable environment for an operator by modifying the set temperature for the fixed time according to the difference of the operator temperature and room temperature. CONSTITUTION:In the case where an air conditioner 1 operates in heating mode and the relation of the set temperature T1 of the air conditioner 1 and the operator temperature T2 in a room is T1>T2 when a remote control signal transmitted from a remote control device 2 is input, detecting temperature by a room temperature sensor part 1b is obtained while the operator temperature and the set temperature included in the remote control signal are obtained. Further in the case where the difference of the room temperature and the operator temperature is equal to the fixed value (for example, +5 deg.) or more, control data for heightening the room temperature (for example, +2 deg.) more than the set temperature are calculated and transmitted to an outdoor control part 1e. As the result a compressor motor 1d is driven until an incorporated timer is timed up and the room temperature control for heightening the room temperature up to only +2 deg. more than the set temperature is performed.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an air conditioner that drives a compressor motor using an inverter method and a 0N10FF control method, and more specifically, to create a more comfortable indoor environment for the operator. The present invention relates to an air conditioner designed to do so.

[Conventional example] Conventionally, this type of air conditioner uses, for example, an indoor temperature detected by a temperature sensing element such as a thermistor included in the indoor unit and a set temperature (temperature set by a remote control device). The compressor motor provided in the outdoor unit is driven according to the difference between Even if the indoor temperature is set to a comfortable temperature, the indoor temperature may not be comfortable depending on the body temperature of the person entering the room.For example, when the air conditioner is running for heating in winter, If the person entering the room has just returned from a trip and is completely cold.

Even though the temperature is normally set to be comfortable, the person entering the room may feel unsatisfied with the room temperature. Also, when the air conditioner is in cooling operation in the summer,
If the person entering the room is warm enough after taking a bath,
Similarly to the above, the person entering the room may feel unsatisfied with the room temperature. In such a case, the only option for the above-mentioned air conditioner is to reset the settings.

However, even if the temperature is reset in this way, the room temperature does not suddenly change, and there is the inconvenience that the temperature must be returned to the original temperature after a certain period of time has elapsed.

This invention was made in view of the above problems, and its purpose is to change the set temperature for a predetermined period of time according to the difference between the operator's temperature and the room temperature, thereby maintaining a more comfortable indoor environment for the operator. An object of the present invention is to provide a method for controlling the operation of an air conditioner.

[Means for Solving the Problems] In order to achieve the above object, the operation control method of the present invention compares the temperature set by the remote control device and the detected temperature in the room, and based on the difference, In an air conditioner that drives a compressor to maintain the indoor temperature at the set temperature, the remote control device is equipped with an infrared sensor that detects the temperature of the operator, and if the operator's temperature is lower than the indoor temperature, the temperature of the operator is lower than the indoor temperature. The temperature in the room is higher than the set temperature above.

When the temperature of the operator is higher than the room temperature, the temperature of the room is kept lower than the set temperature for a certain period of time.

[Example] Embodiments of the present invention will be described below based on the drawings.

Indoor control unit IC that obtains control data for bringing the room temperature closer to the set temperature by receiving remote control signals
and is provided. Also, on the outdoor unit side, there is a compressor motor 1d that operates the refrigerant circuit, and an indoor control unit I.
An outdoor control section 1e is provided to drive and control the compressor motor 1d based on the control data calculated at step C. Note that the indoor control unit IC has a built-in timer (not shown), and this timer is set when control data is transferred to the outdoor control unit 1e.

On the other hand, the remote control device 2 includes an operation button section 2a for operating the air conditioner 1, setting the indoor temperature, etc., and an infrared sensor section for detecting the temperature of the operator of the remote control device 2 (for example, body temperature or clothing temperature). 2b and its operation button section 2a
a control device (CPU) 2c that converts a control signal corresponding to the control signal and a detection signal of the infrared sensor section 2b into a remote control signal; a display section 2d that displays a set temperature value, operator temperature, etc. in the control device 2c; A transmitter 2e is provided that converts remote control signals such as set temperature and operator temperature into infrared rays and emits them.

Next, an operation control method applied to the air conditioner having the above configuration will be explained based on the flowchart of FIG. 3.

First, as shown in FIG. 4, in order to start operation of the air conditioner 1, when the operator who enters the room operates the operation button of the remote control device 2, the operator detects the operation detected by the infrared sensor section 2b. The operator's temperature is calculated, and the transmitter 2e of the remote control device 2 emits a remote control signal indicating the start of operation and the operator's temperature. In addition, when the operation button is operated, a remote control signal of the set temperature is also emitted.

Then, the reception section 1a of the air conditioner 1 receives the above-mentioned operation start information,
Remote control number 43 containing the detected temperature and set temperature is received. The indoor control section 1c starts the following operations based on the temperature detected by the room temperature sensor section 1b (indoor temperature) and the remote control signal received by the reception section 1a.

Here, as shown in FIG. 5, the air conditioner 1 is operated for heating, and the set temperature of the air conditioner 1 is T2. A case where the relationship is T -> T 2 (for example, TX T2>dog) will be explained.

In the indoor control unit IC, the remote control device i! When the remote control signal emitted from 2 is input (step 5TY
), obtain the temperature detected by the room temperature sensor section 1b (step 5T2), and obtain the operator temperature and set temperature included in the input remote control signal (step ST3.4).
. Next, the difference between the room temperature and the temperature of the person handling it is set to a predetermined value (
For example, it is determined whether or not it is greater than +5 deg (step 5T5).

Furthermore, if the temperature difference is +5 deg or more,
Control data for making the indoor temperature higher than the set temperature (for example, +2 degrees) is calculated (step 5T6), and this control data is transferred to the outdoor control unit 1e, and a built-in timer (for example, 1 hour) is set. .

Then, the compressor motor 1d is driven based on the control data until the built-in timer times up (step 5T7), and the indoor temperature is increased by +2 d from the set temperature.
eg, room temperature control is performed to increase the temperature (step 5).

When the built-in timer times up (step 5T7), the indoor control unit 1c calculates control data for setting the indoor temperature to the set temperature T1 with reference to the temperature detected by the room temperature sensor unit 1b, and this control data Outdoor control section 1
e (step 5T8), the compressor motor 1d is driven based on the control data,
Room temperature control is performed to bring the room temperature closer to the original set temperature (step 5T7).

Further, as shown in FIG. 6, the relationship between the set temperature T of the air conditioner 1 and the operator temperature T2 of the remote control device 2 is T, <T.
, (for example, T, -T, (large), step ST
5 proceeds to step 5TIO, where it is determined whether the difference between the indoor temperature and the temperature of the person handling the room is equal to or greater than a predetermined value (-5 deg). Furthermore, the temperature difference is 15 degrees
, or above, control data for lowering the indoor temperature (for example, -2 degrees) than the set temperature is calculated (step 5TII), and this control data is transferred to the outdoor control unit 1e.

A built-in timer (not shown, 0, for example, 1 hour) is set. Then, until the built-in timer times up (step 5T7), the compressor motor 1d is driven based on the control data, and the temperature in the room is lowered by 2 degrees below the set temperature.
Room temperature control is performed to increase the temperature by increasing the temperature (step ST7).

When the built-in timer times up (step 5T7), control data for setting the indoor temperature to the set temperature T4 is calculated by the indoor control unit 1c with reference to the temperature detected by the room temperature sensor unit 1b, and this control data is Outdoor control section 1
e (step ST8.). Then, the compressor motor 1d is driven based on the control data, and room temperature control is performed to bring the indoor temperature closer to the original set temperature.
(Step 5T7).

Further, in the above embodiment, the room temperature sensor section 1b for detecting the indoor temperature is provided on the indoor unit side of the air conditioner, but as shown by the broken line in FIG. It may be placed on the side.
