Description

FIELD OF THE INVENTION This invention relates to electric blankets.

2. Description of the Related Art As shown in FIG. 4, a conventional electric blanket of this type has a blanket body 3 having an electric heater 1 and a temperature detecting means 2 for detecting the temperature of the electric heater 1, and an electric heater 1. Temperature setting means 4 for setting the temperature of, the switch 9 for starting the preheating, the timer 10 for setting the preheating time, and the temperature detecting means 2.
The control means 11 for controlling the energization of the electric heater 1 is provided according to the temperature detected in step 1 and the signal from the temperature setting means 4. With this structure, the switch 9 is turned on, the preheating time is set by the timer 10, and the setting is automatically changed from preheating to an appropriate temperature. (For example,
(Problem to be solved by the invention) However, in the method using the timer as described above,
It takes time and effort to turn on the preheating switch and set the timer, and it is difficult to set the timer because the rise of the blanket temperature varies depending on the room temperature and the type of bedding. Further, there is a problem that the user does not necessarily enter the bed at the time set by the timer, and if the user enters the bed earlier than the set time, the blanket temperature is too high and the user feels uncomfortable unless the timer is turned off.

Therefore, an object of the present invention is to solve such a conventional problem and to automatically set a heater temperature when entering a bed to realize a comfortable sleeping environment.

Means for Solving the Problems In order to achieve this object, the present invention sets a blanket body provided with an electric heater and a temperature detecting means for detecting the temperature of the electric heater, and the temperature of the electric heater. Temperature setting means, horizontal / vertical detection means for detecting the horizontal / vertical direction of the human body when entering the floor, entrance determination means for determining the entrance of the human body based on the output of the horizontal / vertical detection means, and the temperature setting To the electric heater by the difference between the signal from the temperature detecting means and the signal from the setting changing means for changing the set temperature of the temperature setting means by the signal from the means and the bed entrance determining means. And a control means for controlling the energization of the.

Action In the above-mentioned configuration, the electric blanket of the present invention is energized to the electric heater based on a preset high temperature when preheating after power-on, and when the human body enters the floor, the horizontal / vertical state of the human body at that time is set horizontally. The vertical detection means detects, and according to the detection signal, the user automatically switches to the preset temperature during sleep preset by the temperature setting means,
After that, it has the effect of controlling the energization of the electric blanket at the set temperature.

EXAMPLES Examples of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, 1 is an electric heater, 2 is a temperature detecting means for detecting the temperature of the electric heater 1, and the electric heater 1 and the temperature detecting means 2 are arranged in a blanket body 3. 4 is a temperature setting means for setting the temperature of the electric heater 1, 5 is a horizontal / vertical detection means for detecting the horizontal / vertical state of the human body when entering the bed, 6
Is an admission determination means for determining admission of a human body based on the output of the horizontal / vertical detection means 5. Here, as shown in FIG. 2, the horizontal / vertical detecting means 5 includes a detecting portion 5a in a horizontal / vertical state,
It is composed of an output unit 5b that outputs the output from the detection unit 5a to the entrance determination means 6 in a wired or wireless manner. As the detection unit 5a, for example, as shown in FIGS. 3 (a), (b), (c), and (d), detection is performed from the conduction state of the mercury sealed tube,
Alternatively, a device that uses an optical sensor for detection is well known. Reference numeral 7 is a setting change means for changing the set temperature of the electric heater 1 by the signals from the temperature setting means 4 and the entrance determination means 6, and 8 is a difference between the signal from the temperature detection means 2 and the signal from the setting change means 7. It is a control means for controlling the energization of the electric heater 1.

In the above configuration, when the power is turned on, the temperature setting means 4
At that time, preheating is started at a high temperature setting irrespective of the preset temperature preset by the person occupying the floor, and when the human body enters the floor, the horizontal / vertical detecting means 5 detects the horizontal / vertical state of the human body at that time. Based on the detection signal, the user automatically switches to a desired preset temperature during sleep which is preset by the temperature setting means 4, and thereafter, the energization of the electric blanket is controlled at the preset temperature. Due to the above action, it does not take time and effort to manually reset the setting scale, and moreover, without forgetting to switch to the set temperature and falling asleep, there is no danger of waking up due to heat during sleep. You can sleep comfortably.

Effects of the Invention As described above, according to the electric blanket of the present invention, the following effects are obtained.

(1) When the power is turned on, it automatically starts up with a high temperature setting, and when entering the bed, it automatically switches to the appropriate temperature setting for sleep, so there is no need to manually reset the setting scale.

(2) You can sleep comfortably with peace of mind without forgetting to switch to the set temperature and falling asleep to avoid waking up in the middle of sleep.
