Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedroom temperature / humidity control system for adjusting a temperature and / or humidity in the bed to provide a comfortable sleeping environment in a bedroom having a plurality of beds, and a bed constituting the same. It is a thing.

[0002]

2. Description of the Related Art Generally, the temperature inside a bed (bed) in a room is determined by using equipment such as an electric blanket provided on the bed itself and an air conditioner installed in the room. The temperature is adjusted.

[0003]

By the way, in the air conditioner of the air conditioner wall hanging type, since the temperature distribution and the air flow distribution vary, the temperature and humidity near the bed cannot be detected by the sensor built in the air conditioner. Therefore, the conventional air conditioner cannot be said to provide comfortable air conditioning to the sleeping person.

Furthermore, when a plurality of beds are installed in the bedroom, the air conditioning in the room is often uncomfortable because the person's thermal sensation varies depending on whether the bed is hot or cold.

The present invention takes into consideration the above-mentioned problem of adjusting the temperature in a conventional bed, and a bed temperature / humidity control system and a bed that can provide a comfortable hot / cold state even when a plurality of beds are installed. It is intended to provide.

【Example】

(Embodiment 1) The bed 1 has an uneven mat surface, and as shown in FIG. 1, has a ventilation hole 2 in its groove (recess) and is communicated with a blower 3. Further, the heater 4 is embedded in the mat surface so that it can be heated. The control unit of the blower 3 and the heater 4, the temperature sensor 5 and the humidity sensor 6 arranged in the bed 1 are connected to each other in the control unit 7 in the bed 1. Based on the responses of the respective sensors 5 and 6, air blowing and heating are performed. Is adjusted. Further, the temperature sensor 5 in the bed 1 of each bed 1 and the control unit 9 of the air conditioner 8 are connected to the control circuit 10
It is connected to the. The more specific contents will be described below.

The temperature sensor 5 and the humidity sensor 6 for detecting the temperature and humidity inside the bed 1 are arranged in a line as shown in FIG. The position is preferably close to the back of the human body. This is because when the relationship between the temperature distribution inside the bed 1 and the skin temperature was examined, a temperature that was closest to the skin temperature and had little variation could be detected. This is considered to be due to the large body pressure area.

Looking at the movement of the temperature sensor 5, a value close to room temperature is shown, and when a person enters the bed 1, the temperature rises rapidly and reaches 30 ° C. or higher. This detects the presence of a person in the bed. On the contrary, when a person leaves the bed 1, the temperature drops sharply to detect the leaving of the bed. And
Efficient control becomes possible by controlling the room temperature without requiring the thermal sensation of humans only when the person is in bed.

Therefore, when an experiment was carried out in which the subject entered the bed 1 in the awake state and reported the feeling of warmth and cold, sweating, and comfort, the temperature of the back was It correlates well with human thermal sensation. Even in humidity
Humidity on the back correlates well with a person's feeling of sweating. Also,
By placing it in the same place as the temperature sensor 5, it is possible to detect the humidity while detecting the position of the body with the temperature sensor, prevent the influence of the humidity in the bedroom, and detect the change in humidity according to the perspiration state.

A small thermistor is used for the temperature sensor 5.
As the humidity sensor 6, an electric resistance type sensor in which a semiconductor polymer thin film or fine powder is vapor-deposited on a ceramic substrate, or a sensor utilizing expansion and contraction of a nylon ribbon due to a change in humidity is used.

A relationship as shown in FIG. 2 was obtained between the maximum temperature Tmax in the temperature sensor 5 and the thermal sensation. Therefore, Tmax of the temperature sensor 5 is measured, and the thermal sensation is estimated in the following seven stages. -3 = cold, -2 = cool,-
1 = slightly cool, 0 = neither, + 1 = slightly warm, + 2 = warm, + 3 = hot.

The estimated value of the thermal sensation of each bed 1 is processed by the control circuit 10, and the average value thereof is transmitted to the control section 9 of the air conditioner 8. When the value is negative, the room temperature is raised, and when it is positive, the room temperature is lowered. Bed 1
The room temperature near the bed 1 is measured from the value of the temperature sensor 5 at the end of. When this room temperature changes by 1 ° C, the operation of the air conditioner is temporarily stopped, and the thermal sensation of each bed 1 is estimated, and the average value is ±
Operate the air conditioner until it is within 1.

On the other hand, in each of the beds 1, the heater 4 is operated at −2 or less and the blower 3 is operated at +2 or more in accordance with the estimated thermal sensation to create a thermal environment suitable for an individual. As a result, the person in the bedroom can individually sleep in the optimal environment. As a result, if the skin temperature is high after bathing even if the room temperature is low, or if the temperature inside the bed 1 becomes low by kicking out the futon, the condition of a person who cannot be understood simply by monitoring the room temperature I was able to catch it quickly and control it.

Next, the humidity sensor 6 at a place near Tmax
When compared with the value of, and the declared value of sweating feeling (0 = no sweating, 1 = slightly sweating, 2 = sweating, 3 = great sweating),
It was declared as 1 above 75% RH, 2 above 75% RH and 3 above 85% RH. Therefore, the sweating sensations of a plurality of people are estimated and averaged by the control circuit 10. Based on this value, the ventilation strength of the air conditioner is controlled to be weak for sweating feeling 1, medium for 2, and strong for 3. Further, by blowing air toward the bed 1 of a person who is sweating, it is possible to quickly suppress sweating and to suppress the influence on a person who is not sweating.
As a result, the air flow is controlled according to the degree of sweating, and quick detection of sweating allows for quick response and is gentle on the body.
Cooling with less energy consumption is possible. When the sweating subsided, the temperature rise in the bed 1 also stopped, the temperature control weakened, and the ventilation strength weakened, so that it was effective in preventing the coldness of the bed due to the knees after sweating. The temperature and humidity inside the bed 1 are measured at intervals of 5 minutes so that changes in the temperature inside the bed 1 can be quickly dealt with.

(Embodiment 2) In Embodiment 1, the temperature and humidity are adjusted by taking an air conditioner as an example. However, if a radiation panel 11 is provided on a ceiling or a wall as shown in FIG. It is considered to be suitable for temperature control, especially when sleeping, because it does not hit the wind and has little impact on people. Therefore, by adjusting the temperature of the radiation panel 11 by the temperature control unit 12 and performing it in the same manner as the room temperature control of the first embodiment, it is possible to adjust the temperature according to the feeling of warmth and coolness. In Example 1, the average value of the thermal sensation of the sleeping person was used for control, but since the room temperature adjustment of radiation is slower than that of an air conditioner, it is more efficient to control with the most thermal sensation. Further, when sleeping, the body temperature regulation function decreases, so body temperature regulation due to perspiration accounts for a large proportion. Therefore, by adding perspiration detection data, it becomes possible to adjust the temperature according to the individual. Change the degree of temperature adjustment depending on whether sweating occurs (for example, if the number of people who sweated increases from one to two, set the room temperature to 0.5).
By lowering the temperature (° C lowering), it is possible to provide a comfortable sleeping environment by quickly stopping sweating and preventing sleep from being disturbed by sweating at night. For early detection of sweating, it is possible to predict the sweating feeling after the next 5 minutes from the increase in the value of the humidity sensor, and if the temperature exceeds 65% RH, the temperature lowering operation can be performed to enable a faster response.

Also, when the temperature and humidity are controlled by combining the air conditioner and the radiation panel, the temperature and humidity data in the bed 1 is effective. That is, when it is decided to enter the bed due to a sudden rise in the temperature inside the bed 1, the air conditioner is activated to quickly create a comfortable thermal environment, and when sleep onset is detected due to an increase in the humidity inside the bed 1, it is replaced by quiet radiation of sound, You can get a good night's sleep and you can control the temperature and humidity that are kind to your body. When there are multiple beds 1 in the bedroom, the environment control is performed by giving priority to the sleeping person, switching to the radiation panel if there is a sleeping person, and if it happens, if there is still a sleeping person, radiation control will be performed. .

As is apparent from the above description,
The present invention estimates the thermal sensation and sweating sensation based on the output of the sensor and adjusts accordingly, so that a comfortable in-bed climate can be provided to a plurality of people.

Further, the present invention can provide a comfortable in-bed climate corresponding to individual differences by adding a blower function or a heating function to each bed.
