Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a heating device for sleeping such as an electric blanket.

Conventional configuration and problems Residential environments have improved in recent years, but the temperature in the bedroom is low and the temperature difference between when you go to bed and when you wake up is large, especially in cold areas compared to general areas. The cold weather in the morning is unavoidable. For this reason, heating equipment for sleeping has become a necessity, and in particular, electric blankets and the like have come to be widely used as general heating equipment.

Figure 1 is a diagram showing the configuration of a conventional electric town blanket.
is a blanket body, 2 is a heater wire wired to the blanket body 1, 3 is a controller having a built-in control device and power supply circuit for controlling power supply to the heater wire 2, and 4 is a heater wire attached to the controller 3. It is a temperature control knob. Also 5
is a detection line that is wired near the heater wire 2 and detects the temperature of the main body 1.

Fig. 2 shows A-A in Fig. 1 when the conventional blanket body 1 is inserted between the futon and the mattress and the electricity is controlled.
It is a figure which shows the blanket main body temperature in a / line cross section.

As shown in the figure, the temperature of the blanket body varies from room temperature to 1o''.
There is a big change from C to o'C.

This is because the detection wire 6 has to be wired near the heater wire 2 for safety reasons, so the detection wire 5 does not detect the average temperature of the blanket body and detects a temperature close to the temperature of the heater wire 2. This is because the temperature of the blanket itself decreases especially between the heaters when the room temperature decreases.

Further, FIG. 3 is a diagram showing the usage of the electrical loss blanket in the conventional example, where 6 is a futon, 7 is a mattress, and 8 is a human body sleeping and warming itself using the blanket body 1. Figure 4 is a diagram showing the temperature of the blanket body at the cross section taken along the line A-A' in Figure 1 when sleeping or taking warmth as shown in Figure 3. As shown in the figure, the temperature changes from the room temperature of 10"C to 5°C and 20°C. In other words, the temperature of the blanket body during practical use is from the heater wire 2 to the human body 8.
The distribution for each wiring pitch disappears due to the influence of heat generation. As shown in Figure 4, the decrease in the temperature of the blanket itself as the room temperature decreases is most noticeable at the feet because of the distribution of heat dissipation from the human body. As a result, a decrease in skin temperature in the lower limbs of the human body is observed, resulting in a very uncomfortable experience.

In order to prevent this, when controlling the power supply to the heater wire 2 to increase as the room temperature decreases, the temperature of the main body of the blanket reaches the 5th level.
In the figure, the temperature changes from a (room temperature 10''C) to b (room temperature 0''C). This prevents the heat at your feet, but on the other hand, the temperature at your chest increases, making you feel uncomfortable.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and aims to provide a heating device that allows a person to sleep comfortably even when the room temperature changes.

In order to achieve this structural aspect of the invention, the present invention is configured to vary the set temperature in accordance with the output of a room temperature detector.

With this configuration, even if the room temperature changes, the temperature of the blanket body and the temperature inside the bed can be kept substantially constant and approximately equal.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 6 to 9.

Figure 6 shows an embodiment of the sleeping warming device of the present invention.
− It is a configuration diagram of an electric blanket. Components with the same numbers as those in FIGS. 1 and 3 are the same, and therefore the description will be omitted.

A room temperature detector 9 detects the room temperature and sends its output to the controller 3.

FIG. 7 is a control block diagram in the above embodiment, and 1
o is a volume resistor whose resistance value changes in conjunction with the temperature control knob 3, and 12 is an ON signal from the voltage comparator 11.
This is a power supply circuit that receives the OFF signal and turns on and off the power supply.

In the above configuration, the voltage comparator 11 compares the signal from the detection line 5 that detects the temperature of the main body 1 with the combined signal of the room temperature detector 9 and the volume resistor 100,
An ON/OFF signal is sent to the power supply circuit 12. That is, by appropriately selecting the temperature characteristics of the room temperature detector 9, the set temperature of the main body 1 can be increased as the room temperature decreases.

It is a figure which showed the blanket main body temperature of the BB/ line cross section. room 6
`` ' As the temperature decreases, the set temperature of the main body 1 increases, so the power supply state to the heater wire 2 changes, and the room temperature changes between 0°C and 10°C.
"C" forms a temperature distribution as shown in the figure.This is because the pitch of the heater wires at the feet is closer than that at the chest, as shown in Figure 6, so when the power supply increases, the amount of heat generated increases at the feet. This is because it becomes particularly large.

Furthermore, FIG. 9 is a diagram showing the temperature of the blanket body after using the electric blanket of the above embodiment as shown in FIG. 3, similar to the conventional example. As the room temperature decreases from 10°C to OoC, the power supplied to the heater wire 2 increases as described above, but the amount of heat generated increases especially at the feet, where heat radiation from the human body decreases when the room temperature drops, so excessive temperature rise at the chest is prevented. It is possible to prevent the temperature of the blanket body at the feet from decreasing, and to form a substantially uniform and substantially constant temperature distribution, although it is slightly higher at the chest and lower at the feet. This has the effect of allowing you to sleep comfortably even when the room temperature changes. In addition, as a correction value for the change in room temperature of the blanket body temperature, as shown in Fig. 10, the blanket body temperature is O-
Practical tests are being conducted by changing the correction value so that the value increases up to 1deg (in 0.1deg steps). Judging from this result, the feeling will differ slightly depending on the condition of the bedding, but the temperature correction value is -0,
2deg - 0.7deg is the most suitable, and has the effect of allowing a comfortable sleep at all times despite changes in room temperature.

In the above example, electric loss was explained using the configuration of a blanket, but the same effect can be obtained with an electric bed blanket, bed bat, etc. Similar effects can be obtained with a one-wire system using a heater wire with an integrated temperature detection wire, and the present invention is not limited to the above embodiment.

, Effects of the Invention J As described above, the sleeping warming device of the present invention provides the following effects.

(1) Equipped with a control device that controls power supply to the heater wire so that the temperature of the main body reaches a set temperature, and a room temperature detector that detects the room temperature, and changes the set temperature according to the output of the room temperature detector. Since the device is configured to allow the user to sleep comfortably, the amount of heat generated increases as the room temperature decreases, ensuring a comfortable sleep at all times.

(2) Furthermore, according to the present invention, a comfortable temperature can be maintained at all times, not only during transient room temperature changes as described in 1 above, but also during steady room temperature changes throughout the season. There is no need to adjust the adjustment knob, improving usability.

(3) Furthermore, when the room temperature rises, the set temperature is automatically lowered to save energy.
