Abstract

PURPOSE:To secure sound sleep by suppressing a rise in humidity in a room during a 'sleep mode'-operation to control it within a proper range. CONSTITUTION:During a 'sleep model'-operation. when moisture in a room exceeding a specified range is detected with a moisture sensor 6, the 'sleep mode'-operation is stopped and a temperature correction is stopped as made by raising a set temperature in the room by a fixed temperature difference at each fixed time. Then, under such a condition, when a compressor 9 is stopped, a switching is made over to a dehumidifying operation, the set temperature is set to a range (18-24 deg.C) of a dehumidifying start temperature to operate the compressor 9 and an operation rate of the compressor 9 is raised to perform a dehumidification in the room. When the moisture in the room enters a specified range, a return is made to the 'sleep mode'-operation again to lower the set temperature at a proportion of a fixed temperature difference at a fixed time interval. This enables the maintaining of the temperature and moisture at the optimum level during the sleeping thereby keeping a comfortable sleeping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for an air conditioner, and more particularly to controlling humidity in a room during "sleep mode" operation.

[0002]

2. Description of the Related Art Conventionally, when bedtime is reached during cooling operation and the "sleep mode" is set by the sleep timer, the controller performs temperature correction by increasing the set temperature in the room by a constant temperature difference at regular intervals. By stopping the operation of the compressor or switching to a low speed operation and gradually raising the room temperature, it is possible to prevent excessive coldness at bedtime. In this case, the indoor humidity rises as the indoor temperature rises, but the dehumidification effect decreases because the compressor operation is stopped or is shifting to low-speed operation, and it becomes sultry and hot, especially in high-humidity seasons, and prevents sleep. There is a problem that impairs indoor comfort.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and controls an air conditioner that suppresses an increase in indoor humidity during "good night mode" operation and controls an appropriate humidity range. The purpose is to provide a device.

[0004]

In order to achieve the above object, the humidity sensor detects that the indoor humidity exceeds a predetermined humidity range during the "sleep mode" operation,
And when the compressor is stopped, "Good night mode"
The operation was stopped and the dehumidification operation was switched to control. Further, during the "sleep mode" operation, when the humidity sensor detects that the indoor humidity exceeds a predetermined humidity range, and when the compressor is operating at a low speed,
The set temperature increased by the "sleep mode" is reduced by a predetermined temperature difference, and the compressor is operated to control the dehumidification.

[0005]

According to the above structure, when the humidity sensor detects that the indoor humidity exceeds the predetermined humidity range during the "sleep mode" operation, the "sleep mode" operation is stopped, and the room interior is reset at regular intervals. Stop the temperature correction that raises the set temperature by a constant temperature difference.If the compressor is stopped in that state, switch to dehumidification operation and set the set temperature to the dehumidification start temperature.
Set the temperature in the range of 18 to 24 ° C, operate the compressor to increase the operation rate of the compressor to dehumidify the inside of the room, and restart the "sleep mode" when the humidity in the room falls within the specified humidity range. Then, the set temperature is lowered at a constant temperature difference rate at regular time intervals. Also, when the indoor humidity exceeds the specified humidity range and the compressor is operating at low speed without stopping, the set temperature at that time is lowered to a temperature corresponding to the dehumidification start temperature to operate the compressor. The rate is increased and the room is dehumidified.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the present invention. The control unit 1 takes in control conditions of the air conditioner such as operating mode and the like from an input setting unit 2 including a main body operation unit or a remote control device, and the control unit The indoor temperature TR, which is stored in the memory 3 of No. 1 and is attached to the front surface of the indoor unit, detects the indoor temperature TR, and the set temperature Ts stored in the memory 3 is compared by the first comparing means 5, The indoor humidity sensor 6 provided in the air guide passage detects the indoor humidity, compares it with the reference range of the indoor humidity stored in the memory 3 by the second comparing means 7, and controls the compressor based on the result. The operation of the compressor 9 is controlled via the circuit 8, and the operation of the indoor blower 10 is controlled by the control unit 1.
The input setting means 2 sets operation modes such as cooling / drying / heating, the set temperature Ts of the room, the reference range of the indoor humidity, the setting of the timer 11, the air volume setting, etc. It is stored in the memory 3.

When the cooling operation is set, the control unit 1 starts the operation of the air conditioner according to the input operation mode, drives the indoor blower 10, detects the indoor temperature TR by the indoor temperature sensor 4, and stores it in the memory. Room temperature Ts stored in 3
The first comparing means 5 compares the signal with a signal corresponding to the difference and sends the signal to the compressor control circuit 8 to control the operation of the compressor 9. Further, when the "sleep mode" is set by the timer 11, the set temperature Ts is increased stepwise by a constant temperature difference α at regular time intervals, and the indoor temperature TR is gradually increased.
It prevents the room from getting too cold at bedtime and ensures a good night's sleep. When the operation is continued in this state, the indoor humidity rises, and in a high humidity season, it is humid and hot and disturbs the sleep. Therefore, the indoor humidity sensor 6 detects the indoor humidity and the indoor humidity reference range stored in the memory 3 is detected. The second comparison means 7 compares the above, and when the indoor humidity exceeds the reference range, a signal is sent to the compressor control circuit 8 to forcibly switch to the dehumidifying operation. When it is switched to the dehumidifying operation, the "sleep mode" is stopped, and the set temperature Ts is lowered by the predetermined temperature difference β from the set temperature Ts which is increased stepwise,
The compressor 9 is forcibly driven, the air volume of the indoor blower 10 is further suppressed, and the dehumidifying operation is performed to lower the indoor humidity and ensure a good night's sleep.

FIG. 2 is a diagram showing a temporal change in the room temperature according to the present invention. When the "sleep mode" is set, the control unit 1 sets the set temperature Ts to a constant temperature difference at a constant time (for example, every 30 minutes). Raise it by α and gradually raise the indoor temperature TR until it becomes lower than the outdoor temperature and comfortable for sleeping, and keep that state until the "sleep timer" expires. In this state, the set temperature Ts becomes high, the operating rate of the compressor 9 is reduced, and in a high humidity season, the humidity in the room is high and it becomes hot and humid.
Above all, the indoor humidity is detected by the humidity sensor 6, and when the humidity exceeds a predetermined humidity range, the set temperature Ts is lowered by a predetermined temperature difference β to forcibly drive the compressor 9 to start the dehumidifying operation. ing. At the time when the dehumidification image is completed, the set temperature Ts is similarly increased at a constant temperature difference α for a fixed time.
The room temperature TR is gradually increased.
