Description

Description: TECHNICAL FIELD The present invention relates to a control device for an air conditioner that performs comfortable temperature control during sleep.

2. Description of the Related Art Conventionally, various methods have been considered to improve comfort during sleep. FIG. 3 is an explanatory diagram showing an example of a conventional control of a cooling and sleeping operation. Third
In the figure, the time t ₀ "Good night" button of the air conditioner is pushed with-bed at therewith raised by θdeg as automatically or based on the manually set temperature (Tset) by the outdoor temperature and the like at the same time, It was to keep it as it was until it woke up (t ₁ ).

Problems to be Solved by the Invention However, in the conventional control of the cooling-good-night operation as described above, at the time of entering the bed, the criterion of the temperature control of the “good-night” operation is the room temperature at the time of entering the bed, that is, the comfort in everyday life. Since the temperature is set, there is a problem that it is possible to feel sultry and awake due to the rise of the claw value due to the bedding such as futons and towels that are worn at bedtime, and it is not possible to create a comfortable sleeping environment. .

The present invention has been made in view of the above problems, and has an object to create a comfortable sleeping environment when entering a bed by controlling a set temperature in consideration of a living rhythm of a human body when entering the bed.

Means for Solving the Problems To achieve the above object, an air conditioner of the present invention is provided.
Room temperature setting means for setting the indoor temperature, operation determining means for determining the operation of the cooling and good night operation, time measuring means for measuring the elapsed time from the operation of the cooling and good night operation, and detecting a signal from the operation determining means Control means for lowering the set temperature by the first temperature by the room temperature setting means and then increasing the second temperature higher than the first temperature by a predetermined time by the time measuring means. .

Operation The operation of the above configuration is as follows.

ADVANTAGE OF THE INVENTION This invention can create a comfortable sleeping environment at the time of entering a bed by controlling the set temperature in consideration of the biological rhythm of the human body at the time of entering a bed.

Embodiment An embodiment of the present invention will be described below with reference to FIG. 1 and FIG.

In FIG. 1 (a), 1 is an indoor heat exchanger, 2 is a blower for an indoor heat exchanger, and 3 is an indoor blower circuit, and these constitute an indoor unit 4. The indoor unit 4 may have a well-known configuration, and is connected to a well-known outdoor unit (not shown) to form a well-known refrigeration cycle for cooling or heating. In FIG. 1 (b),
5 is a room temperature setting means, 6 is an operation determining means, 7 is a time measuring means, and 8 is a control means for correcting a set temperature based on signals from the operation determining means 6 and the time measuring means 7. FIG. 2 shows an example of the set temperature controlled by the above configuration.

The time of entering the bed is determined by the operation determining means 6, and the temperature (Tset) automatically or manually set according to the outdoor temperature at that time is corrected by the room temperature setting means 5 by a correction value θ ₁ d.
eg by (a first temperature) shifted the Tset downward, thereby shifted upwards then time measuring unit 7 by after t ₁ hour elapsed theta ₂ deg (second temperature). Here, the magnitude of the temperature correction value has a relationship of θ ₂ > θ ₁ , and the set temperature after elapse of t ₁ is higher than the set temperature Tset before entering the bed. Thus, for a certain time after entering the bed, the temperature set by θ ₁ deg is lower than the set temperature before entering the bed.
By lowering the temperature only, it is possible to reduce the feeling of being sultry due to the increased heat insulation performance of the bedding such as a futon or a towel that is worn at bedtime. Further, after a certain period of time, the temperature is increased by θ ₂ deg. As a result, the set temperature is raised by (θ ₂ −θ ₁ ) deg from the set temperature Tset before entering the bed, so that the metabolic rate during falling asleep is increased. It is possible to control the room temperature in accordance with the biological rhythm of the human body as seen in a decrease, and it is possible to provide a comfortable sleep environment when entering and falling asleep.

As is clear from the above embodiment, the control device of the air conditioner of the present invention detects the time of entry by the operation determining means, shifts the set temperature downward by the room temperature setting means, and thereafter, by the time measuring means. By shifting the temperature above the set temperature at the time of entering the bed after a certain period of time, it is possible to control the wear of the bedding when entering the bed and the biological rhythm of the human body in consideration. As a result, comfortable air conditioning can be performed without awakening due to the humid heat when entering the bed.
