Description

[Detailed description of the invention] Industrial applications The present invention relates to a heating device for sleeping such as an electric blanket.

Configuration of conventional example and its problems Figure 1 is a configuration diagram of an electric blanket showing a conventional example.
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. Furthermore, reference numeral 5 denotes a detection line that is wired near the heater wire 2 and detects the temperature of the main body 1. FIG. 2 is a diagram showing the temperature of the blanket body in the section taken along the line A-A' in FIG. 1 when the conventional blanket body 1 is inserted between a standard comforter and a mattress and the electricity supply is controlled. As shown in the figure, the temperature of the blanket body varies upward and downward depending on the room temperature, for example, between the room temperature of 10°C and o'C. This is because the detection wire 5 has to be wired near the heater wire 2 for safety reasons, so the detection wire 6 does not detect the average temperature of the blanket body and has a temperature close to the temperature of the heater wire 2. This is because by detecting this, when the room temperature drops, the temperature of the blanket itself decreases, especially between the heaters.

3 is a diagram showing the state in which the electric blanket in the conventional example is used, where 6 is a comforter, 7 is a mattress, and 8 is a human body sleeping and warming itself using the blanket body 1. Figure 4 shows the first temperature when sleeping and taking warmth as shown in Figure 3.
It is a diagram showing the temperature of the blanket body at the A-A' cross section in the figure, and the temperature of the blanket body is 10°C, 5°C depending on the room temperature.
C, O''C as shown in the figure. In other words, the temperature of the blanket body in practical use is
is strongly affected by heat generation, and the distribution by wiring pitch disappears. -And, as shown in FIG. 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, which is extremely uncomfortable. In addition, in order to prevent this, if the power supply to the heater wire 2 is controlled to increase as the room temperature decreases, the temperature of the blanket body will be the fifth.
In the figure, the temperature changes from a (room temperature 10''C) to b (room temperature 0''C). This prevents the temperature at your feet from dropping, but on the other hand, the temperature at your chest increases, making you feel tight and uncomfortable.

1. Purpose of the Invention The purpose of the present invention is to solve these conventional problems and to provide a heating device that allows a person to sleep comfortably even when the room temperature changes.

Structure of the Invention In order to achieve this object, the present invention differs the heat generation density of the heater wire between the foot side and the chest side of the main body, and
This configuration allows the temperature set by the control device to be varied in accordance with the output of the room temperature detector. With this configuration, the body temperature and the temperature inside the bed can be kept approximately constant and approximately equal even if the room temperature changes. can.

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

FIG. 6 is a configuration diagram of an electric blanket in one embodiment of the sleeping heating device of the present invention. 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
0 is a volume resistor whose resistance value changes in conjunction with the temperature control knob 3, and 12 is a 0N voltage 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 6 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.

Figure 8 shows the main body 1 in the above embodiment inserted between a standard comforter and a mattress, and when the power supply is controlled, B - in Figure 6.
It is a figure which showed the blanket main body temperature of the B/ line cross section. As the set temperature of the main body 1 rises as the room temperature decreases, the power supply state to the motor wire 2 changes, forming a temperature distribution as shown in the figure between room temperatures of 0''C and 10''C. This is because the pitch of the heater wires at the feet is closer than that at the chest, as shown in FIG. 6, so that when the power supply increases, the increase in heat generation is particularly large at the feet.

Furthermore, FIG. 9 is a diagram showing the temperature of the blanket body when the electric blanket of the above embodiment is used as shown in FIG. 3, similar to the conventional example. As the room temperature decreases from 10°C to O''C, the power supplied to the heater wire 2 increases as described above, but the amount of heat generated increases especially at the feet where the heat radiation from the human body decreases when the room temperature drops, so the temperature at the chest area increases. It prevents the temperature of the blanket body at the feet from decreasing without causing excessive rise, and creates an approximately uniform and almost constant temperature distribution, although it is slightly higher at the chest and lower at the feet.For this reason, even when the room temperature changes. This has the effect of allowing you to sleep comfortably at all times.

In the above embodiment, an electric blanket was used as a heating device for sleeping, but the same effect can be obtained with an electric blanket, a pad pad, etc. Instead of the so-called two-wire system in which the wires 5 are separated, a single-wire system using a heater wire with an integrated temperature sensing layer can also provide similar effects, and is not limited to the above embodiment.

7.--Effects of the Invention As described in Section 2, the sleeping warming device of the present invention provides the following effects.

(1) a main body, a heater wire wired so that the heat generation density differs between the chest side and the foot side of the main body, and a control device that controls power supply to the heater wire so that the temperature of the main body reaches a set temperature; The device is equipped with a room temperature detector that detects the room temperature, and is configured to vary the set temperature according to the output of the room temperature detector, so that as the room temperature decreases, the amount of heat generated at the feet increases, It works to create a uniform and constant temperature distribution without causing an excessive rise in temperature at the chest area, allowing you to sleep comfortably at all times.

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

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