Abstract

PURPOSE:To create always a comfortable in-bed environment by a method wherein a first sensing means for sensing a room temperature and a second sensing means for sensing an in-bed temperature are arranged and further a controlling means for controlling an indoor temperature in reference to a sensed temperature of the second sensing means is provided. CONSTITUTION:A room temperature is detected by a first sensing means 6, and an in-bed temperature is detected by a second sensing means 7. A controlling means 8 may perform an indoor temperature control in reference to a detected temperature of the second sensing means 7. If 'a good-night mode' is selected, a comfortable in-bed temperature thetai is set to have a range of thetaL<=thetai<=thetaH. In general, these two values are thetaL=33 deg.C and thetaH=34 deg.C. When the in-bed temperature thetai is detected by the second sensing means 7, it is compared with that of the comfortable zone, and of the detected temperature thetai is lower than the lower limit value thetaL, the set temperature thetar is increased. If it is judged that the detected temperature thetai is not lower than the lower limit value thetaL and lower than the upper limit value thetaH the set temperature thetar is kept as it is. In turn, if it is judged that the in-bed temperature thetai is not lower than the upper limit value thetaH, the set temperature thetar is decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an air conditioner that controls room temperature to maintain a comfortable bed temperature during sleep.

BACKGROUND OF THE INVENTION Until now, various methods have been devised to improve comfort during sleep. FIG. 4 shows an example of the conventional operation of the so-called "sleep mode" when sleeping under heating.

In the figure, when the heating operation is being performed at a set temperature of θ1, when the "Sleep" button is pressed at the same time as entering the bed (time T1), the "Sleep Mode" is automatically entered. In other words, the set temperature θ1 is
Continue heating operation as it is, and at T2 after ΔT time, Δ
The set temperature is lowered by σ to operate at a temperature of θ2, and thereafter, heating operation is performed at a set temperature of θS while maintaining a constant time interval (3 units) and a constant temperature drop (Δθ) relationship. That is what it is.

Problems to be Solved by the Invention However, in the conventional example described above, the set temperature is gradually lowered depending on the time elapsed after going to bed, and there is a direct relationship with the human body in bed. do not have. Therefore, for example, when the amount of futon is different or when the metabolic rate during sleep is different, there is a problem that it is not possible to always create a comfortable environment in the bed.

In view of the above problems, the present invention detects the temperature inside the bed,
The purpose is to create a comfortable sleeping environment at all times by controlling the room temperature so that the detection results fall within a certain temperature range.

Means for Solving the Problems In order to solve the above problems, the air conditioner of the present invention includes:
An indoor unit composed of a suction port, a heat exchanger, a blower, and an air outlet is provided with a first detection means for detecting room temperature and a second detection means for detecting the bed internal temperature, and further includes a first detection means for detecting the internal bed temperature. The device is equipped with a control means for controlling the indoor temperature based on the detected temperature.

Effect: With the above configuration, the air conditioner of the present invention allows the second air conditioner to
By detecting the temperature inside the bed by the detection means and controlling the room temperature detected by the first detection means so that the detected result falls within a certain temperature range, a comfortable environment inside the bed can be created at all times. can.

EXAMPLE Hereinafter, an air conditioner according to the present invention will be explained with reference to the drawings.

FIG. 1 shows an air conditioner showing an embodiment of the present invention.

In FIG. 1, 1 is an inlet, 2 is a heat exchanger, 3 is a blower, 4 is an air outlet, 5 is an indoor unit composed of these, 6 is a first detection means for detecting room temperature, and 7 is a bed. A second detection means 8 for detecting the internal temperature is a control means for controlling the indoor temperature based on the temperature detected by the second detection means 7.

Next, the operation of this embodiment will be explained with reference to FIGS. 2 and 3.

FIG. 2 shows the case where this embodiment is installed in a bedroom, and when sleeping, the first detection means 6 can detect the room temperature and the second detection means 7 can detect the temperature inside the bed.

FIG. 4 is a flowchart when this embodiment is applied during heating sleep.

Now, when "Do not disturb mode" is selected, step 1 (
Sl), the range of comfortable bed temperature (θi) is θL
It is set as ≦U1≦σH, and this range is called a comfort zone. In general, θL=33CC), θ@= 34 ('
C) is the place value. Next, in step 2 (S2),
The second detection means 7 detects the bed internal temperature (θ■), and compares it with the comfort zone as in step 3 (53), and the detected temperature (θI) is determined to be the lower limit of the comfort zone (θ
When it is determined that the temperature is lower than L) (Yes), the process proceeds to step 4 (S4) and the set temperature (θr)e is raised. In step 3 (S3), if it is determined that the detected temperature (θI) is not lower than the lower limit value (θL) of the comfort zone (+no), the process proceeds to step 5 (SS), where the upper limit value of the comfort zone is set (+no).
If it is determined that it is lower than (σH) (Yes), step 6
Proceeding to (S6), the set temperature (θ, ) is maintained as it is. Also, in step 5 (S5), the bed internal temperature (
θI) is not lower than the upper limit of the comfort zone (θH) (
If the determination is No, the process proceeds to step 7 (S7) and the set temperature (θr) is lowered. In this way, the internal bed temperature (
Even after a signal to change or maintain the set temperature (θF) is issued, the process returns to before step 2 (92), as if comparing θ1) with the comfort zone.
Then, the second detection means 7 detects the bed internal temperature (θ1), and the same flow is repeated thereafter.

Although the explanation has been given above using heating sleeping as an example, the same concept can be applied to cooling sleeping.

Effects of the Invention As described above, the present invention provides an indoor unit comprising a suction port, a heat exchanger, a blower, and an air outlet, with a first detection means for detecting the room temperature and a second detection means for detecting the internal temperature of the bed. and a control means for controlling the temperature in the room based on the temperature detected by the second detection means.When sleeping, the second detection means detects the internal temperature of the bed, and the detected temperature is within a certain range. By controlling the set temperature in the room, it is possible to always provide a constant environment in the bed and to have a comfortable sleep.
