Abstract

PURPOSE:To get a comfortable sleeping by a method wherein a set temperature is varied in a period after elapsing of a specified time at a going-to-bed to a getting-up time in such a way as a room temperature becomes a set temperature of getting-up time when a getting-up time occurs. CONSTITUTION:A micro-computer 5 acting as a cooling or heating capability calculating means having means for setting or varying a cooling or heating capability is comprised of a timer 6 for calculating a time from a mode changing-over operation, an input circuit 7, a CPU 8, a memory 9 and an output circuit 10. A cooling or heating capability variable device 11 changes the number of revolutions of a compressor 12 in response to an output from the output circuit 10 and then a cooling capability is controlled When a well-sleeping mode is turned on at the time t1, a flow chart stored in the micro-computer 5 starts to operate, the set temperature is changed to a temperature of the going-to-bed time and then a room temperature is controlled to a temperature at the time of going-to-bed by the time t2. As the time t2 comes, a temperature converting range from t2 to t3 is calculated in reference to a time up to the getting-up time t3 and to a temperature difference between the temperature at the time of going-to-bed and the temperature at the getting-up time. Then, the set temperature is gradually varied for every certain time interval in such a way as the temperature becomes the temperature at the getting-up time at the time t3. As the getting-up times t3 comes, the temperature becomes the getting-up time temperature and then a room temperature is controlled at the temperature of the getting-up time until a well-sleeping mode is turned off at the time t4.

This thermosetting switch (16) is provided with a normal temperature scale of 22 to 32°C and a shift temperature scale of 12 to 22°C facing each other at positions sandwiching the knob. Lamps (light emitting diodes) (20a) (20b) are provided at positions corresponding to these temperature scales, respectively. Further, a noft switch (21) is provided above the thermosetting switch (16) in the operation section (4).

FIG. 5 shows the control circuit.

A timer time setting switch (13) and a timer changeover switch (14) are connected to the timer (6). This timer (6) counts the time set by the timer time setting switch (13) in accordance with the setting mode of the timer changeover switch (14). In addition, the thermo setting switch (2

After that, when the timer (6) finishes counting the set time t, the temperature setting section (25) returns to the initial set temperature (23°C
) again. In this way, the on/off control of the heating operation based on the comparison between the normal set temperature and the room temperature is restarted.

[Problem to be solved by the invention]

Now, as explained in the conventional example, in a conventional air conditioner, when the sleep mode is set during heating, for example, the set temperature changes by 1. The temperature I lowered by Qdeg was the set temperature for sleeping. For this reason, the temperature at which a person feels comfortable is determined by the amount of physical activity and amount of clothing. In other words, the comfortable temperature for the same user when awake varies depending on the situation.

However, when sleeping, unlike when awake, the amount of physical activity and amount of clothing of the same user remains almost constant.

In other words, the comfortable temperature at bedtime is not significantly different from the set temperature at bedtime the previous day. That is, the comfortable temperature when awake and the comfortable temperature when sleeping are independent.

In addition, whether room temperature conditions are important for obtaining good quality sleep, or because the temperature setting during sleep can only be set at the time of going to bed, unlike when awake, the quality of sleep may be affected by the temperature setting at the time of going to bed. There is a characteristic that it is determined.

With conventional air conditioners, the set temperature at bedtime is determined by the level of crystallinity you set when you wake up, so the set temperature at bedtime changes depending on the amount of activity and amount of clothing you wear before going to bed, making it difficult to get a good quality sleep. There was a problem that there were cases where it could not be obtained.

[Means to solve the problem]

The air conditioner according to the present invention has a heating and cooling capacity variable device that can change the capacity, a temperature detector that detects the room temperature, a set temperature when entering the bed, a set temperature when waking up, and a wake-up time that are stored in advance. The device has means for changing the set temperature from a certain time after going to bed to when waking up so that the set temperature is reached at the time of bed.

f'11] The air conditioner of the present invention has an air conditioning/heating capacity increasing device, a set temperature at bedtime, a set temperature at wake up, and a wake up time that are stored in advance. It has a set temperature change means that changes the set temperature from a certain time after bedtime to when you wake up, so you can set the set temperature during sleep independent of the set temperature when awake, and adjust the amount of physical activity and amount of clothing during sleep. matched. It creates a comfortable sleeping environment for the user.
