Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to heating devices for sleeping, particularly temperature control devices thereof.
This is for the sake of ease.

Conventional structure and problems When describing conventional sleeping heating equipment using an electric loss blanket as an example, the heater placed inside the blanket is wired to heat the head and feet, and the heater pitch is rough on the chest and densely placed around the feet. However, since it is fixed, it does not suit everyone, as there are a wide variety of people who have cold feet due to their constitution, age, etc., and people who have hot feet. Also, before going to bed, preheat on a high scale for about an hour.
After warming the inside of the futon sufficiently, I change the dial to a scale that will give me the appropriate temperature, but this often happens, especially in the elderly, when I get up to go to the bathroom at night and my body gets cold. Using the scale at that time, it feels dull, so in order to warm up rapidly at this time, I raise the scale and increase the temperature of the blanket. However, most of the electric blankets to date do not have a device to restore the scale, so you have to keep your eyes closed until your body warms up, and you have to return the scale to its original value, but in many cases you have to raise the scale. I fell asleep, and after a while I woke up feeling hot and lowered the scale. These things are extremely inconvenient for getting a comfortable sleep.

Therefore, a strong start method can be considered. This works by pressing the strong start switch on the electric blanket controller.
The dial scale is designed to simplify dial operation during preheating by automatically lowering the temperature to the dial scale after the blanket temperature rises to a strong temperature even if it is set to the normal scale during sleep. be. It is conceivable to use this type of strong start switch to recover from a cold body caused by getting up to use the toilet in the middle of the night, but since this method once raises the temperature to a high level on the strong scale, the sleeper can temporarily stay in the high temperature bed. This use should be avoided due to the exposure to temperature.

In addition, if the indoor temperature is high or your body is sufficiently layered due to drinking or bathing, the futon preheated with an electric blanket may feel hot, and in this case, lower the scale and go to bed. However, in the early morning it was cold and I had to wake up and readjust the scale.

In addition, elderly people cannot see the letters on the dial unless they use reading glasses, and the scales must be operated by hand while sleeping, which may cause problems such as setting the scale too high or low, making it difficult to obtain the appropriate temperature.

Purpose of the Invention The present invention eliminates these conventional problems.In addition to making it possible to obtain a head-cold-foot-heat ratio suitable for one's constitution, when the need arises, the temperature obtained on the dial scale can be changed for a while. By raising or lowering the temperature at your feet and then automatically restoring it to the original temperature, we aim to create heating devices for sleeping, such as electric blankets and electric mattresses, that are easy to use and make it easy to get a comfortable sleep. be.

Structure of the Invention In order to achieve this object, the present invention is provided with two heaters, a temperature sensor, and a temperature control circuit to separately warm the foot portion and body portion of the blanket.

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is a diagram showing the main body of an electric blanket as an example of a warming device for sleeping, where 30 is the fabric of the blanket, 3 is the leg side, 51, -1 4 is the part corresponding to the torso side, and there are two Heaters 5 and 5' with temperature sensors are arranged on the foot side and the torso side.

The heaters 5, 5' with temperature sensors are constructed by winding the heating elements m8, 8' shown in FIG. 6
′ wrapped around it and then covered with an outer covering. In addition, it is also possible to arrange a well-known structure in which a linear temperature sensor and a heater, which are often used in electric blankets, are separated, one pair each on the foot side and the torso side.

Figure 2 is a diagram showing the temperature control part of the electric blanket, 1o1 indicates the case of the control box, 1
02 is a temperature adjustment dial that moves the temperature adjustment variable resistance 10' shown in FIG. 5 on the torso side, and 103 is a dial that moves the temperature adjustment variable resistance 10 on the leg side. variable resistance 10
, 10' is a 2-axis 2-set variable resistance, so dial 10
2 and 103 are provided on the same axis, and these dials 102 and 103 can be moved simultaneously or individually.

In particular, by shifting the relative positions of the indicated values of dials 102 and 103, dial 1o3 (foot side temperature) can be made higher or lower than dial 102 (body side temperature), and the relationship between them can be changed. You can check it on the dial at a glance.

Figure 7 shows 1 attached to the rotating shaft of a 2-shaft, 2-set variable resistor.
The figure shows a spring plate 6o provided between the pair of dials 102 and 103 to create a frictional relationship between the two dials 102 and 103.

61 and 62 are rotation axes of the variable resistors 10 and 10'. With this, by fixing either dial 102 or 103 by hand and moving the other dial by hand, the relative value of both dial positions can be changed, or by rotating one dial without fixing either dial. Since a spring plate 60 is provided as a relative value variable device that moves both dials, 2
Even with two dials, it is easy to operate. Non-retentive pushbutton switches 104 and 1015 shown in FIG.
The contacts 18 and 2o are closed only when the button is pressed, and the contacts open when the button is released. These two push button switches 10
4, 106 is a start switch for the temperature raising and lowering circuit 77, which will be described later. When the switch is pressed, the temperature at the foot of the blanket can be raised or lowered for the time set by the timer. .

FIG. 3 is a graph showing the temperature on the leg side of the sleeping heater when the timer circuit for temperature increase or temperature decrease shown in FIG. 2 is activated. When the pushbutton switch 104 or 105 is not operated, the temperature shown by curve A is within the appropriate temperature range, but
Press the temperature increase valve button switch 104 at time T1.The temperature increase timer circuit works to raise the temperature of the foot to a temperature similar to that of the mouth.After the foot has been sufficiently warmed, the temperature returns to the original temperature at time T2, when the timer circuit ends. Revenge.

Further, a temperature-lowering timer circuit is activated in which the temperature-lowering valve button switch 105 is pressed at time T3, and the foot temperature is lowered to a temperature such as 0. The temperature is returned to the original temperature at time T4, when the timer circuit ends. These pushbutton switches 104 and 105 are used by the sleeper to temporarily warm up or cool down the body. Figure 5 shows the temperature control circuit of this sleeping heater. Yes, it is easier to understand if you look at it in relation to Figures 1 and 2.

1 is a temperature control circuit on the leg side of the heating device for sleeping, and 2 is a temperature control circuit on the body side.

The temperature control circuit 2 on the shell side controls the heater 5' with a temperature sensor on the shell side described in FIG. 9' is a resistor, and 10' is a variable resistor that is connected to the temperature control variable resistor 1o of the temperature control circuit 1 on the foot side and is connected to two sets of two axes. 15' is a pulse generating element, 16' is a transformer, and 17' is a thyristor. When the temperature of the heating device is low, the impedance of the temperature sensor layer 7' is high, so the resistor 9' - variable resistor 1 is connected from the power supply 22.
0' The voltage between the signal line 6' and the heating line 8' due to the temperature detection signal current flowing from the signal line 6' to the temperature sensor layer 7' to the heating line 8' to the power supply 22 is large, and the pulse generating element 16' is ignited. As the pulse current flows through the pulse transformer 16', a pulse wave is also induced on the secondary side of the pulse transformer 16', enters the gate of the thyristor 17', conducts the thyristor 17', and heats the heating wire 8'. generates heat.

When the heater 5' with temperature sensor is sufficiently warmed up, the temperature sensor layer 7
Since the impedance of ' is lowered and the voltage drop 9 .\\ is lowered, the pulse generating element 16' is not fired, and the cyrisk 17' is not conductive, so that the heat generation of the heating wire 8' is also stopped.

The temperature adjustment effect is performed in this way, and the variable resistor 10'
By changing the resistance value of the temperature sensor layer 7', the impedance of the temperature sensor layer 7' necessary to obtain the ignition starting voltage of the pulse generating element 16' changes, and in connection with this, the adjusted temperature of the heating device can be changed.

1 is the foot side temperature control circuit, and parts that are the same as the torso side temperature control circuit are given the same symbols by removing the dash from the same number. In particular, the foot side temperature control circuit is characterized by the provision of a temperature increase timer circuit and a temperature decrease timer circuit. That is, the temperature increase timer circuit is composed of a start switch 18 that is linked to the pushbutton switch 104, a timer circuit 19, a timer output contact 14, and resistors 11 and 12.

Since the timer output contact 14 is a normally closed contact, it is always closed when the timer is not working, causing a voltage drop across the resistor 9 due to the current flowing through the resistor 9゜11.12, and temperature control after the variable resistor 1o. Although a low voltage of 10 Ω is supplied to the circuit, when the timer start switch 18 is closed, the timer circuit 19 closes the contact 14 until the time expires.
Since the current flowing through the resistors 11 and 12 increases rapidly, the voltage drop across the resistor 9 decreases, and the temperature control circuit 1 becomes higher.

The temperature drop timer circuit is composed of a timer start switch 20, a timer 21, and a short circuit of a resistor 12 via a timer output contact 13.

When pushbutton switch 105 is pressed, start switch 2
0 is closed, the timer circuit 21 closes the output contact 13 when the time is about to expire, and as the current flowing through the resistors 9 and 11 increases, the voltage drop across the resistor 9 increases, and the temperature control circuit 1
The regulating temperature of will decrease.

The circuit shown in FIG. 4 is an example in which a relative value variable device including a variable resistor 50 is added to the foot-side temperature control circuit 1 of the temperature control circuit shown in FIG. In this example, the temperature control circuits for both the foot side and the body side have two variable resistors of 10°10' on one axis, and one dial as shown at 111 in FIG. 6.

11. Then, by finely adjusting the temperature of the foot side by moving the variable resistor 5o using the slide lever shown at 110 in Figure 6, the temperature of the foot side and body side on the same dial scale can be adjusted. Made the relationship variable. Generally speaking, the temperature difference between the foot side and the torso side is about 10℃, which is good for use, but since there are considerable individual differences, the temperature difference between the foot side and the torso side on the same dial scale is 0℃~ It is best to be able to adjust the temperature between about 20 degrees Celsius.

In the example shown in FIG. 2, the device for varying the relative value of the temperature on the torso side and the foot side is configured such that the temperature control variable resistors of the torso side and foot side temperature control circuits are two sets of two shafts, and the rotation angle of both dials 102, 103 is adjusted. In order to make it possible to freely vary the relationship individually and to rotate both dials together, a spring plate 6Q provided between both dials 102 and 103 was used to provide friction, but the cam, clutch, The 21 variable resistors may also be turned by other mechanical means such as gears or belts.

B. Also, as shown in FIG. 4, a variable resistor 50 was provided separately from the variable resistors 10 and 10' for temperature control to vary the temperature only on the leg side, but the variable resistor 50 was installed in the torso side temperature control circuit. Even if it is provided in the temperature control circuits for both the foot side and the torso side, it is effective as a means for achieving the purpose of changing the temperature difference between the torso side and the foot side.

Effects of the Invention As stated above, the present invention is extremely easy to operate.
It is possible to create a heating device for sleeping that makes it easy to obtain a comfortable temperature. According to the example, when your body is cold after getting up to go to the toilet at night, or when your body is hot after taking a bath when going to bed, etc.
If you press the temperature increase or decrease pushbutton switch as necessary, only the feet will remain heated or cooled for a certain period of time, and then return to the temperature set with the dial, allowing the user to warm up or cool down their body. It feels good to use because you can fall asleep without waiting.

In addition, the temperature increase or temperature decrease pushbutton switch provided on the controller can be easily made large, and all you have to do is press it, so there is no need to operate it while looking at the letters on a small dial in a sleepy state. 137.7 It is convenient for people who need glasses because they do not need to wear them. Also, by installing a device that changes the relative value of the temperature on the foot side and the body side, it is possible to adjust the ratio of the temperature on the foot side and the body side. Since you can choose freely, you can get a head-cold-foot-heat ratio that suits your constitution, making it easy to get a comfortable sleep.

In particular, when the temperature on the foot side was temporarily raised or lowered, the temperature on the foot side was raised or lowered, which caused the chest to become too warm, resulting in dry throat, feeling groggy, and sweating. There is little to do.
