DETAILED DESCRIPTION OF THE INVENTION
Embodiments according to the present invention will be described below with reference to the drawings. In addition, about the same structure in each figure, the same code | symbol is attached | subjected and the description is abbreviate | omitted.
[0026]
(First embodiment)
FIG. 1 is a diagram showing the appearance of the bedding according to the first embodiment of the present invention, and FIG. 2 is a diagram showing the internal structure of the bedding according to the first embodiment of the present invention. As shown in FIG. 1, the bedding 10 has the same size as a general mattress on which a human body can lie.
[0027]
  1 and 2 includes a shoulder heating wire heater 1a, a foot heating wire heater 1b, and a space material.(Inner layer material)2a, intake part(Opening for air)2b, exhaust part(Opening air)2c, blower 2d, indoor temperature sensor 3, shoulder bed temperature sensor 4a, foot bed temperature sensor 4b, temperature control unit 5 and operation unit 6.
[0028]
The heating device 1 (see FIG. 6) raises the temperature in the bed, and the heating wire heater 1a for the shoulder opening disposed near the shoulder of the human body and the heating wire heater 1b for the foot disposed near the foot of the human body. And is configured. The shoulder heating wire heater 1a is arranged in an S shape in the bed near the shoulder of the human body, and raises the temperature in the bed near the shoulder of the human body. The heating wire heater 1b for the feet is arranged in an S shape in the bed near the feet of the human body, and increases the temperature in the bed near the feet of the human body. The shoulder heating wire heater 1 a and the foot heating wire heater 1 b are individually temperature controlled by the temperature control unit 6. By placing the shoulder heating wire heater 1a at a position corresponding to the shoulder of the human body, it is possible to intensively raise the temperature inside the bed of the shoulder, which is particularly difficult to block outside air.
[0029]
The heat absorbing device 2 (see FIG. 6) lowers the temperature in the bed, and includes a space member 2a, an intake portion 2b, an exhaust portion 2c, and a blower 2d. The space member 2a is formed of a material having air permeability and elasticity, for example, urethane foam, and allows the gas taken in by the intake portion 2b to pass therethrough. The intake portion 2b has openings formed on both sides of the bedding body 11 from the vicinity of the shoulder of the human body to the vicinity of the back, and takes outside air into the space member 2a from the opening. The exhaust part 2c is formed with an opening at the lower corner of the bedding body 11, and exhausts the gas in the space member 2c to the outside. The blower 2d is provided in front of the exhaust part 2c. For example, by rotating a fan, outside air is taken into the space member 2a from the intake part 2b, and gas that has passed through the space member 2a is discharged from the exhaust part 2c. An air flow is generated in the main body 11. The heat absorbing device 2 absorbs heat by taking in outside air, can lower the temperature of the space material 2a to the temperature of outside air, and can reduce the temperature in the bed. In addition, since the air intake portions 2b for taking in outside air are provided on both sides from the vicinity of the shoulder of the human body to the vicinity of the back, the outside air is quickly taken under the human body, and the temperature in the bed can be lowered efficiently. Moreover, since the opening part of the intake part 2b is not blocked | closed when the bedclothes main body 11 is covered, the user can use a favorite sheet.
[0030]
The indoor temperature sensor 3 is provided in the vicinity of the intake portion 2b for taking in outside air. The indoor temperature sensor 3 measures the indoor temperature, that is, the outside air temperature. Thus, by providing the indoor temperature sensor 3 in the intake portion 2b, it is possible to know the outside air temperature when taking in outside air.
[0031]
The bed temperature sensor 4 (see FIG. 6) measures the temperature in the bed, and the bed temperature sensor 4a for the shoulder located near the shoulder when the human body lies, and the human body temperature when the human body lies down. And a bed bed temperature sensor 4b disposed in the vicinity of the feet. The shoulder mouth temperature sensor 4a measures the temperature in the bed near the shoulder of the human body. The bed temperature sensor 4b for the feet measures the temperature in the bed near the feet of the human body. Since the temperature sensor 4a for the shoulder bed and the temperature sensor 4b for the foot bed are arranged at a position substantially below the human body when using the bedding, it is possible to accurately detect the temperature felt by the human body. Can do.
[0032]
The room temperature sensor 3, the shoulder bed temperature sensor 4a, and the foot bed temperature sensor 4b are, for example, a thermistor, a thermocouple, or a semiconductor temperature sensor.
[0033]
FIG. 3 is a view showing a cross section of the bedding 10. As shown in FIG. 3, the heating wire heaters 1a and 1b are arranged under the space material 2a, and the space material 2a and the heating wire heaters 1a and 1b are sandwiched between the front surface material 7a and the back surface material 7b. As the surface material 7a, a material having high confidentiality and moisture absorption, for example, cotton proofed down is used. By arranging the heating wire heaters 1a and 1b under the space material 2a, the heat of the heating wire heaters 1a and 1b is not directly transmitted to the human body, and the air blowing effect of the space material 2a is hardly hindered. Yes.
[0034]
In this way, by using a material rich in confidentiality and hygroscopicity as the surface material 7a, only the blower 2d provided in the vicinity of the exhaust part 2c for discharging the gas in the space material 2a to the outside is used to draw the outside air into the intake part. 2b. However, when the performance of the blower 2d is high, by using a material having good air permeability for the surface material 7a, for example, gauze, it becomes easier to inhale air around the human body when lying down, and the temperature in the bed is more It can be easily lowered.
[0035]
The temperature control unit 5 controls the heating wire heaters 1a and 1b and the blower 2d based on the detection values of the indoor temperature sensor 3 and the bed temperature sensors 4a and 4b, thereby setting the temperature in the bed to a set temperature suitable for sleeping. Keep on.
[0036]
Here, the set temperature suitable for sleep will be described. FIG. 4 is a diagram for explaining a set temperature suitable for sleep. In addition, the vertical axis | shaft in FIG. 4 represents temperature, and a horizontal axis represents time. In general, it is said that the bed temperature at which comfortable sleep is obtained is around 33 degrees. Furthermore, it is preferable that the temperature at the time of getting up is slightly higher than the temperature at the time of entering the floor, and the temperature of the feet is preferably set to be a few degrees higher than the temperature of the shoulder. For example, the foot temperature may be 1 to 5 degrees higher than the shoulder temperature, and more preferably 2 degrees.
[0037]
Therefore, as shown in FIG. 4, the temperature control unit 5 performs control so that the temperature at the foot always becomes a set temperature that is several degrees higher than the temperature at the shoulder. Thus, the temperature in the bed located at each part of the human body can be controlled to a temperature corresponding to each part. In addition, a timer for measuring the elapsed time from the time of entering the floor is provided, and the temperature control unit 5 changes the set temperature according to the elapsed time so that the temperature at the time of getting up becomes higher than the temperature at the time of entering the floor. To control. That is, the bedtime set in advance, for example, the temperature in the bed after 5 hours is set to be higher than the temperature at the time of entering the bed.
[0038]
Furthermore, since the temperature in the bed varies depending on the user's preference, by configuring the set temperature to be switchable in multiple stages, for example, three stages of “high”, “medium”, and “low”, It can correspond to the desired temperature.
[0039]
Further, the temperature control unit 5 performs control so that the set temperature is low when the detected temperature of the indoor temperature sensor 3 is high (for example, summer), and the detected temperature of the indoor temperature sensor 3 is low (for example, winter). ), And control to increase the set temperature.

[0052]
The timer 7 measures the elapsed time from the time of entering the floor, and starts counting (timekeeping) with the power on at the time of entering the floor as a trigger.

The set temperature storage unit 82 stores in advance a plurality of set temperatures having temperature characteristics that change according to the elapsed time from entering the floor to rising. In the present embodiment, since the set temperature can be switched in three stages of “high”, “medium”, and “low”, the set temperature storage unit 82 is lower than the first set temperature and the first set temperature. The second set temperature and the third set temperature lower than the second set temperature are stored. Further, for each of the first to third set temperatures, there are a first to third shoulder opening temperature and a first to third foot setting temperature. The standard outside air temperature storage unit 83 stores a standard outside air temperature variation having a temperature characteristic that changes in accordance with an elapsed time from entering the floor to getting up. The conversion coefficient storage unit 84 stores a conversion coefficient for converting the set temperature according to the outside air temperature. The conversion coefficient will be described later.
[0054]
Next, temperature control of the bedding 10 in the first embodiment will be described. FIG. 7 is a diagram for explaining the temperature control of the bedding 10 in the first embodiment. In FIG. 7, the vertical axis represents temperature, and the horizontal axis represents time.
[0055]
First, the timer 7 starts measuring time using a power-on signal from the operation unit 6 as a trigger. The room temperature sensor 3 detects the outside air temperature at the time t and outputs the detected outside air temperature to the temperature control unit 5. The temperature control unit 5 compares the outside air temperature detected by the room temperature sensor 3 with the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83. Here, when the outside air temperature detected by the indoor temperature sensor 3 is the same as the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83, the temperature control unit 5 stores the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so as to have the set temperature at the stored time t.
[0056]
For example, when the first set temperature is set by the operation unit 6, the temperature control unit 5 stores the temperature near the shoulder detected by the shoulder bed temperature sensor 4 a and the set temperature storage unit 82. The first shoulder temperature setting Ts is compared. Here, when the temperature near the shoulder detected by the shoulder bed temperature sensor 4a is higher than the first set temperature Ts for the shoulder, which is stored in the set temperature storage unit 82, the temperature control unit 5 The blower 2d is driven until the temperature near the shoulder detected by the bed temperature sensor 4a is equal to the first shoulder opening temperature Ts stored in the setting temperature storage unit 82. In this way, by controlling the rotational speed of the blower 2d according to the difference between the detection values of the indoor temperature sensor 3 and the bed temperature sensor 4, the temperature should not be lowered too much when the temperature to be lowered is small. If the temperature is high, the temperature can be lowered rapidly.
[0057]
Further, the temperature control unit 5 uses the shoulder mouth temperature when the temperature near the shoulder mouth detected by the shoulder bed temperature sensor 4a is lower than the first shoulder mouth set temperature Ts stored in the set temperature storage unit 82. The shoulder heating wire heater 1a is driven until the temperature near the shoulder detected by the in-bed temperature sensor 4a becomes the same as the first shoulder opening temperature Ts stored in the setting temperature storage unit 82.
[0058]
Similarly, when the temperature in the vicinity of the foot detected by the foot bed temperature sensor 4b is higher than the first foot setting temperature Tf stored in the set temperature storage unit 82, the temperature control unit 5 The fan 2d is driven until the temperature in the vicinity of the foot detected by the bed temperature sensor 4b is equal to the first foot setting temperature Tf stored in the set temperature storage unit 82. Further, the temperature control unit 5 uses the foot temperature when the temperature in the vicinity of the foot detected by the foot bed temperature sensor 4b is lower than the first foot setting temperature Tf stored in the set temperature storage unit 82. The foot heating wire heater 1b is driven until the temperature in the vicinity of the foot detected by the bed temperature sensor 4b becomes the same as the first foot setting temperature Tf stored in the set temperature storage unit 82.
[0059]
On the other hand, when the outside air temperature detected by the room temperature sensor 3 is different from the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83, the temperature control unit 5 is stored in the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so that the set temperature after the conversion is obtained by multiplying the set temperature at the time t by the conversion coefficient stored in the conversion coefficient storage unit 84.
[0060]
FIG. 8 is a diagram for explaining a conversion coefficient for converting the set temperature according to the outside air temperature. In addition, the vertical axis | shaft in FIG. 8 represents preset temperature (relative value), and a horizontal axis represents external temperature (relative value).
[0061]
As shown in FIG. 8, the conversion coefficient storage unit 84 sets the value of the standard outside air temperature at time t as 1, the value of the set temperature at time t as 1, and the detected outside air temperature and the set temperature as relative values. When the detected outside air temperature is higher than the standard outside air temperature, the set temperature becomes low, and when the detected outside air temperature is lower than the standard outside air temperature, the set temperature becomes high. The conversion coefficient is stored. In addition, the straight line K shown in FIG. 8 is an example, The inclination etc. are not limited to this.
[0062]
For example, when the temperature Tb of the outside air detected by the indoor temperature sensor 3 at time t is higher than the standard outside air temperature Ta, the temperature control unit 5 uses the conversion coefficient stored in the conversion coefficient storage unit 84 as the first step. By multiplying the set temperature Tf for use, the temperature is converted to the set temperature Tf ′ (Tf> Tf ′), and the heating device 1 and the heat absorbing device 2 are controlled so that the converted set temperature Tf ′ is obtained. That is, as shown in FIG. 8, when the standard outside air temperature Ta is set to 1 and the first foot set temperature Tf is set to 1, the relative value at the temperature Tb is expressed as Tb / Ta, and the relative set temperature at Tb / Ta is The value is represented by Wb, and the relative value Wb of the set temperature at Tb / Ta is used as the conversion coefficient. Accordingly, the set temperature Tf ′ is a value obtained by multiplying the first set temperature Tf for the foot and the conversion coefficient Wb.
[0063]
Further, the temperature control unit 5 converts the conversion coefficient stored in the conversion coefficient storage unit 84 into the set temperature Ts ′ (Ts> Ts ′) by multiplying the first shoulder opening set temperature Ts, and converts the converted temperature. The heating device 1 and the heat absorption device 2 are controlled so as to be the set temperature Ts ′. That is, as shown in FIG. 8, when the standard outside air temperature Ta is set to 1 and the first shoulder opening temperature Ts is set to 1, the relative value at the temperature Tb is represented by Tb / Ta, and the relative relative temperature of the set temperature at Tb / Ta. The value is represented by Wb, and the relative value Wb of the set temperature at Tb / Ta is used as the conversion coefficient. Accordingly, the set temperature Ts ′ is a value obtained by multiplying the first shoulder opening temperature Ts by the conversion coefficient Wb.
[0064]
Further, for example, when the temperature Tc of the outside air detected by the room temperature sensor 3 at time t is lower than the standard outside temperature Ta, the temperature control unit 5 uses the conversion coefficient stored in the conversion coefficient storage unit 84 as the first conversion coefficient.

[0077]
Next, temperature control of the bedding 20 in the second embodiment will be described.
[0078]
First, the timer 7 starts timing with a detection signal from the human body detection sensor 22 as a trigger. In addition, when the detection signal from the human body detection sensor 22 is not input, the temperature control unit 5 controls the heating wire heaters 1a and 1b and the blower 2d so as to enter an energy saving mode for reducing power consumption. The room temperature sensor 3 detects the outside air temperature at the time t and outputs the detected outside air temperature to the temperature control unit 5. The humidity sensor 21 detects the humidity in the bed at time t, and outputs the detected humidity to the temperature control unit 5. The temperature control unit 5 compares the outside air temperature detected by the room temperature sensor 3 with the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83. Here, when the outside air temperature detected by the indoor temperature sensor 3 is the same as the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83, the temperature control unit 5 stores the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so as to have the set temperature at the stored time t.
[0079]
On the other hand, when the outside air temperature detected by the room temperature sensor 3 is different from the standard outside air temperature at the time t stored in the standard outside air temperature storage unit 83, the temperature control unit 5 is stored in the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so that the set temperature after the conversion is obtained by multiplying the set temperature at the time t by the conversion coefficient stored in the conversion coefficient storage unit 84.
[0080]
Further, the temperature control unit 5 compares the humidity detected by the humidity sensor 21 with the standard humidity at the time t stored in the standard humidity storage unit 85. Here, when the humidity detected by the humidity sensor 21 is the same as the standard humidity at the time t stored in the standard humidity storage unit 85, the temperature control unit 5 is stored in the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so that the set temperature is reached at time t.
[0081]
On the other hand, when the humidity detected by the humidity sensor 21 is different from the standard humidity at the time t stored in the standard humidity storage unit 85, the temperature control unit 5 at the time t stored in the set temperature storage unit 82. The heating device 1 and the heat absorption device 2 are controlled so as to be the set temperature after conversion obtained by multiplying the set temperature by the conversion coefficient stored in the conversion coefficient storage unit 84.
[0082]
FIG. 12 is a diagram for explaining the conversion coefficient for converting the set temperature according to the humidity in the bed. In addition, the vertical axis | shaft in FIG. 12 represents preset temperature (relative value), and a horizontal axis represents humidity (relative value).
[0083]
As shown in FIG. 12, the conversion coefficient storage unit 84 sets the standard humidity value at time t to 1, the set temperature value at time t as 1, and represents the detected humidity and the set temperature as relative values. The conversion coefficient represented by the straight line L is stored such that the set temperature is low when the detected humidity is higher than the standard humidity and the set temperature is high when the detected humidity is lower than the standard humidity. ing. In addition, the straight line L shown in FIG. 12 is an example, The inclination etc. are not limited to this.
[0084]
For example, even if the temperature is the same, when the humidity is high and when the humidity is low, the sensible temperature is higher when the humidity is high. Therefore, a more comfortable sleep environment can be provided by changing the temperature in the bed according to the humidity in the bed detected by the humidity sensor 21.
[0085]
As described above, since the temperature of at least one of the heating device 1 and the heat absorbing device 2 is controlled according to the humidity in the bedding main body 11 detected by the humidity sensor 21, the temperature is controlled to be low when the humidity is high. However, by controlling the temperature to be high when the humidity is low, the temperature in the bed can be maintained at a comfortable temperature according to the humidity.
[0086]
In addition, when the humidity value detected by the humidity sensor 21 is high, the temperature control unit 5 is a heating wire heater for shoulders even if the temperature detected by the bed temperature sensors 4a and 4b is lower than the set temperature. Humidity can be lowered by controlling so that 1a, the heating wire heater 1b, and the air blower 2d are driven simultaneously.
[0087]
In addition, since the elapsed time from the time of entering the human body to the time of getting up is measured by the timer 7, the temperature of at least one of the heating device 1 and the heat absorbing device 2 is controlled according to the elapsed time measured by the timer 7. The temperature in the bed that changes between entering and waking up can be controlled according to the elapsed time from entering to waking up, and the temperature in the bed can be adjusted according to the elapsed time from entering to waking up. Can be kept at temperature.
[0088]
Further, when a human body is detected by the human body detection sensor 22, the temperature of at least one of the heating device 1 and the heat absorbing device 2 is controlled. Since control such as not controlling the temperature is performed by the device and the heat absorption device, the temperature in the bed can be maintained at a comfortable temperature depending on the presence or absence of a human body.
[0089]
Furthermore, since the human body detection sensor 22 detects that the human body has entered the floor and the timer 7 starts counting, even if the power is turned on in advance before the user enters the floor, the set temperature changes appropriately. And the temperature in the bed can be controlled.
