Description

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

BACKGROUND TECHNOLOGY As shown in FIGS. 3 and 4, a conventional electric blanket of this type includes a blanket main body 3 provided with an electric heater 1 and a temperature detecting means 2 for detecting the temperature of the electric heater 1, and a preheating a switch 12 that starts heating, a timer 6 that sets the preheating time, and a high temperature setting when the switch 12 is turned on, and a setting that returns the high temperature setting to the temperature set by the temperature setting means 4 according to a signal from the timer 6. The changing means 10, the temperature detected by the temperature detecting means 2, and the set temperature changing means 1
It had a control means 11 for controlling the temperature by comparing it with a set temperature of 0. With this configuration, by turning on the switch 12 and setting the preheating time using the timer 6, the preheating can be automatically returned to the appropriate temperature setting.

Problems to be Solved by the Invention In the method using a timer as described above, it is necessary to turn on the preheating switch and set the timer before going to bed, which is very time-consuming and requires a lot of effort. I often forgot. Furthermore, it is not always the case that you go to bed at the time set on the timer, so if you go to bed earlier than the time set on the timer, the temperature will remain set at a high temperature and you will have to turn off the timer. There is a problem that if you go to sleep without turning off the timer, the temperature of the blanket will be too hot and you will feel uncomfortable.

Means for Solving the Problems The present invention provides a blanket body equipped with an electric heater and a temperature detection means for detecting temperature, a temperature setting means for setting the temperature of the electric heater, and temperature change/pressure change/heat flow. a sleeping detection means for detecting going to bed based on a change, etc.; a timer; a calculating means for calculating a preheating start time from the bedtime time determined by the sleeping detecting means and the timer; and a preheating start calculated by the calculating means. A storage means for storing time, a stop button for stopping energization to the electric heater, and at the preheating start time stored in the storage means, energization is started at a high temperature setting regardless of the set temperature set by the temperature setting means. , a setting changing means for returning the temperature to the temperature set by the temperature setting means when going to bed in response to a signal from the sleeping detection means and stopping energization to the electric heater in response to a signal from the stop button; a temperature detecting means and a setting changing means; This electric blanket is equipped with a control means for controlling the power supply to the heater based on the difference between When this happens, the stop button can be automatically reset by a signal from the setting change means that starts energization at a high temperature setting.

Effect With this configuration, when the power is first turned on, preheating starts at a high temperature setting, and when it is detected that the person has gone to bed based on a signal from the sleeping detection means, the preheating temperature is changed from the high temperature setting to the preset appropriate temperature. Automatically return to settings, press the stop button when you wake up,
Stop energizing the electric heater. The next preheating start time is calculated and memorized based on the bed entry time at this time, and at this preheating start time, the stop button is automatically reset and the power is automatically turned on at a high temperature setting regardless of the temperature set by the setting temperature means. . In this way, just by turning on the power and pressing the stop button when you wake up, it will automatically start preheating at a high temperature setting so that it is a comfortable temperature when you go to bed, and then return to the appropriate temperature setting when you go to bed, saving you time and effort. You can fall asleep comfortably without any hassle.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, an electric heater 1 and a temperature detection means 2 are arranged in a blanket body 3, and a temperature setting means 4 for setting the temperature of the electric heater 1.
and a sleeping detection means 5 for detecting going to bed.
a timer 6; a calculation means 7 for calculating the next preheating start time from the bedtime time determined by the timer 6 and the bedtime detection means 5; and a storage means 8 for storing the preheating start time calculated by the calculation means 7. ,
A stop button 9 for stopping energization to the electric heater, and a stop button 9 for starting energization at a high temperature setting regardless of the set temperature set by the temperature setting means 3 when the time stored in the storage means 8 arrives, and the sleeping detection means 5 When entering the bed is detected by a signal from the temperature setting means 3, the temperature is returned to the temperature set by the temperature setting means 3,
The electric heater is configured of a setting changing means 10 for stopping the energization of the electric heater 1 by the stop button 9, and a control means 11 for controlling the energizing to the heater based on the difference between the temperature detecting means 2 and the setting changing means 10. When you turn on the power with a blanket, preheating starts at a high temperature setting regardless of the preset temperature, and when you go to bed in response to a signal from the sleep detection means 5, the setting change means 10 changes the temperature to the appropriate temperature set by the temperature setting means 3. It automatically returns to the settings, calculates and stores the next preheating start time from the time you enter the bed, and when the memorized preheating start time comes, it automatically starts energizing at the high temperature setting, and when you enter the bed, it returns to the appropriate temperature setting. Since the heat is turned back on, you can fall asleep comfortably without having to turn on a preheat switch.

The stop button pressed when waking up is configured to automatically return to normal state when the stored preheating start time is reached by a signal from the setting change means that sets the high temperature setting to be energized.

Effects of the Invention The electric blanket of the present invention provides the following effects (1) Just by turning on the power, it automatically starts preheating at a high temperature setting so that it reaches a comfortable temperature when you go to bed. The temperature will then be set to the preset temperature.

(2) When you go to bed, the temperature setting automatically switches from the high temperature setting to the appropriate temperature setting, so there is no need to reset the temperature as you would with a timer system.
