Description

[Detailed description of the invention] Industrial applications The present invention relates to an electric blanket.

2. Description of the Related Art As shown in FIG. 4, a conventional electric blanket of this type includes a blanket body 3 provided with an electric heater 1 and a temperature detection means 2 for detecting the temperature of the electric heater 1; , a switch 9 to start preheating, a timer 10 to set the preheating time, and a signal from the temperature setting means 4 and the temperature detected by the temperature detection means 2.
A control means 11 for controlling energization to the electric heater 1 was provided. This configuration had the effect of turning on the switch 9, setting the preheating time with the timer 10, and automatically changing the setting from preheating to an appropriate temperature. (For example, Japanese Utility Model Publication No. 48-81; He issue) Problems to be solved by the invention However, in the method using a timer as described above,
It takes time to turn on the preheating switch and set the timer, and it is difficult to set the timer because the temperature of the blanket varies depending on the room temperature and the type of bedding. In addition, it is not always the case that the patient goes to bed at the time set on the timer, and if the patient goes to bed earlier than the set time, there is a problem in that if the timer is not turned off, the temperature of the blanket will be too high and the patient will feel uncomfortable.

SUMMARY OF THE INVENTION An object of the present invention is to solve these conventional problems and automatically set the heater temperature when going to bed, thereby realizing a comfortable sleeping environment.

Means for Solving the Problems In order to achieve this object, the present invention provides a blanket body provided with an electric heater and a temperature detection means for detecting the temperature of the electric heater, and setting the temperature of the electric heater. temperature setting means; horizontal/vertical detecting means for detecting horizontal/vertical orientation of a human body when entering the bed; bed entry determining means for determining whether a human body enters the bed based on the output of the horizontal/vertical detecting means; and the temperature setting. a setting changing means for changing the set temperature of the temperature setting means in response to a signal from the disconnecting means; A control means for controlling energization to the heater is provided.

Function: With the above configuration, the electric blanket of the present invention energizes the electric heater based on a preset high temperature during preheating after turning on the power, and when the human body enters the bed, it detects the horizontal and vertical states of the human body at that time. The horizontal/vertical detection means detects the temperature, and based on the detection signal, the temperature is automatically switched to the desired sleeping temperature set by the user in advance using the temperature setting means.
Thereafter, it has the effect that the electricity supply to the electric blanket is controlled at the set temperature.

Example Embodiments 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 detection means for detecting the temperature of the electric heater 1, and the electric heater 1 and the temperature detection means 2 are arranged in the blanket body 3. 4 is a temperature setting means for setting the temperature of the electric heater 1; 5 is a horizontal/vertical detecting means for detecting the horizontal/vertical state of the human body when entering the bed; 6 is a temperature setting means for setting the temperature of the electric heater 1;
is a bed entry determination means for determining whether a human body has entered the bed based on the output of the horizontal/vertical detection means 5. Here, as shown in FIG. 2, the horizontal/vertical detecting means 5 is composed of a detecting section 5a for detecting the horizontal/vertical state, and an output section 5b for outputting the output from the detecting section 5a to the bed entry determining means 6 by wire or wirelessly. be done. Detection part 5
For example, FIG. 3(a).

As shown in (b), (C), and (d), methods that perform detection based on the conduction state of a mercury-filled tube or methods that perform detection using an optical sensor are well known. Reference numeral 7 indicates a setting change means for changing the set temperature of the electric heater 1 based on the signals from the temperature setting means 4 and bed entry determining means 6; and 8 indicates a setting change means for changing the set temperature of the electric heater 1 based on the signal from the temperature detection means 2 and the signal from the setting change means 7. This is a control means for controlling the supply of electricity to the electric heater 1.

In the above configuration, when the power is turned on, the temperature setting means 4
When the person enters the bed, the horizontal/vertical detection means 5 detects the horizontal/vertical state of the human body at that time, and In response to the detection signal, the temperature is automatically switched to the desired sleep temperature set by the user in advance using the temperature setting means 4, and from then on, the electricity supply to the electric blanket is controlled at the set temperature. As a result of the above-mentioned effects, there is no need to manually reset the setting scale, and there is also no need to forget to switch to the set temperature and fall asleep and wake up in the middle of sleep feeling hot. You can sleep with peace of mind and comfort.

Effects of the Invention As described above, the electric blanket of the present invention provides the following effects.

(1) When you turn on the power, it automatically starts up at a high temperature setting, and when you go to bed, it automatically switches to the appropriate temperature setting for sleeping, so you don't have to go through the trouble of manually resetting the setting scale.

(2) There is no need to forget to switch to the set temperature and fall asleep and wake up in the middle of sleep feeling hot.
You can sleep in peace and comfort.
