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 technology Although the housing environment has improved in recent years, the temperature in the bedroom is low and the temperature difference between going to bed and waking up is large, especially in cold areas, where the temperature difference is large compared to general areas, making it difficult to avoid the cold in the morning. do not have. For this reason, heating equipment for sleeping has become a necessity, and electric blankets and the like have come to be widely used as general heating equipment. FIG. 4 is a configuration diagram of a conventional electric fence blanket, where 1 is a blanket body, 2id is a thermal heater wire wired to the blanket body 1, and a is a control for power supply to the thermal heater wire 2. 4 is a temperature control knob attached to the controller 3. Also, 5#-j the thermal heater M2
This is a temperature-sensitive layer provided inside the main body 1 to detect the temperature of the main body 1.

Problems to be Solved by the Invention Figure 5 shows A--A in Figure 4 when the blanket body 1 of the above conventional example is inserted between a standard hook and a futon and the energization is controlled.
It is a figure which shows the blanket main body temperature in A' cross section.

As shown in the figure, the temperature of the blanket body varies greatly depending on the room temperature.

In this case, the temperature-sensitive layer 5 does not detect the average temperature of the blanket body, but only the temperature of the thermal heater Is2, and in this case, when the room temperature drops, the temperature of the blanket body inevitably decreases, especially between the heaters. It's for a reason. At this time, the person taking the temperature sees a drop in skin temperature, which makes them feel very uncomfortable.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to place a room temperature detector in the outlet at the end of the power cord, and to vary the set value according to the output of the room temperature detector. It is something that makes you

Function: With this configuration, the temperature of the main body fluctuates according to changes in room temperature, so the temperature inside the bed is always kept constant and uniform, allowing a comfortable sleep. Furthermore, since the room temperature detector is located at the outlet at the end of the power cord, the room temperature detector is not affected by the person taking the heat or bedding, ensuring normal operation at all times, improving usability.

Embodiment Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings.

FIG. 4 is a configuration diagram of an electric blanket in an embodiment of the sleeping warming device of the present invention. The same numbers as those in FIG. 4 are the same parts, so the explanation will be omitted. 9//i is a room temperature detector that detects the room temperature and sends its output to the controller 3. Also, there are 13 power cords, and 14 is an outlet at the end of the cord.

FIG. 2 is a control block diagram in the above embodiment. Components with the same numbers as those in FIG. 4 are the same, and therefore the description will be omitted. 10 is a variable resistor whose resistance value changes in conjunction with the temperature control knob 4; 12t'i voltage comparator 1;
The power supply circuit that receives the ON-OFF signal from 1 is a power supply circuit that turns on and off the power supply.

In the above configuration, the voltage comparator 11 compares the signal from the temperature sensitive layer 5 that detects the temperature of the main body 1 with the composite signal of the room temperature detector 9 and the variable resistor 10, and Send ON/OFF signals to. 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.

Therefore, it is very effective to be able to sleep comfortably even when the room temperature changes. In addition, as shown in Figure 3, as a correction value for the change in room temperature of the blanket body temperature, for a change in room temperature that decreases by 1 d@g, the blanket body temperature is adjusted to 0 to 1 d@g (0, 1 d@g).
・We conducted a practical test by changing the correction value so that the temperature rises up to q increments.As a result, when the correction temperature is below 0.2 d@g, you start to feel cool, and when the correction temperature is above 0.7 d@g, you feel hot. There is. Judging from this result, the feeling will differ slightly depending on the condition of the bedding, but as a temperature correction value, the room temperature is 104 degrees.
An increase of 2 to 7 d%q is most suitable for a decrease in g, and has the effect of allowing a comfortable sleep at all times despite changes in room temperature.

Furthermore, in the above configuration, even if the controller 3 is caught inside the bed, the room temperature detector 9 is located at the outlet 14, so the room temperature can always be accurately detected and no abnormal operation will occur.

In addition, in the above example, the configuration of an electric blanket was explained.
Similar effects can be obtained with electric bed blankets, bed pads, etc.
Furthermore, the same effect can be obtained by using a two-wire structure in which the heater wire and the detector are separated, rather than the so-called one-wire type in which the heat-sensitive heater +1l12 is used as in the embodiment, and the present invention is not limited to the above-mentioned embodiment.

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

(1) The room temperature detector is located in the outlet, so it can always accurately detect the room temperature without being affected by the human body or bedding.
Improves safety.

(2) Since the set temperature increases as the room temperature decreases, the temperature inside the bed can always be kept constant and uniform, making it possible to always sleep comfortably.

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