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 temperature setting means 4 for setting the temperature of
A control means 7 is provided for controlling energization of the electric heater 1 based on the detected temperature and a signal from the temperature setting means 4.

This configuration had the effect of turning on the switch 5, setting the preheating time with the timer 6, and automatically changing the setting from preheating to an appropriate temperature. (For example, Jikko 48-8
(No. 146 Publication) Problems to be Solved by the Invention However, with the above-mentioned method, it takes time and effort to turn on the preheating switch and set the timer, and the temperature rise of the blanket varies depending on the room temperature and the type of bedding. , the timer setting is internal. In addition, the patient does not necessarily go to bed at the time set by the timer, and if the timer to go to bed earlier than the set time is turned off, the temperature of the blanket becomes too high, causing discomfort.

SUMMARY OF THE INVENTION An object of the present invention is to solve such conventional problems, to reliably and easily change the setting of the heater temperature upon entering the bed, and to realize a comfortable working environment.

Means for Solving the Problems In order to achieve this object, the present invention includes a blanket body provided with an electric heater and a temperature detection means for detecting the temperature of the electric heater, and a temperature of the electric heater is set. a temperature setting means, a clock, a notification means, a switch for turning on and off the notification function of the notification means, a notification time setting means for setting a notification time by the notification means, a dielectric temperature setting means and a switch for turning on and off the notification function. a setting changing means for changing the set temperature of the temperature setting means based on a signal from a switch; and control for controlling energization to the electric heater based on a difference between a signal from the temperature detecting means and a signal from the setting changing means. The means are provided.

Operation In the electric blanket of the present invention having the above configuration, the electric heater is energized based on a high temperature set in advance during preheating after the power is turned on, and when a human body enters the bed, the time setting of the notification means and the notification are performed. When the function switch is turned on, that is, when the alarm clock is set, the temperature is automatically switched to the desired constant temperature during sleep that the user has set in advance using the temperature setting means, and from then on, that setting is automatically changed. The temperature controls the energization of the electric blanket. Also, when you wake up,
When the notification function is canceled, it has the effect of turning off the electricity to the electric heater in conjunction with this.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, an electric heater 1 and a temperature detection means 2 for detecting the temperature of the electric heater 1 are provided on a blanket body 3. 8 is a controller containing a control circuit. FIG. 2 shows a control block diagram. Temperature setting means 4 for setting the temperature of the electric heater 1 and setting changing means 10 for changing the set temperature based on the output from the alarm function on/off switch 9
and a control means 7 which controls the energization of the electric heater 1 based on the signals from the setting change means 10 and the temperature detection means 2, a clock 11, an alarm 12, and an alarm time which sets the notification time by the alarm 12. It is composed of a setting means 13. FIG. 3 shows the external appearance of the controller 8.

A display section 14 for displaying the current time and alarm setting time, a setting switch 15 for the alarm time setting means 113, an on/off switch 16 for energizing the electric heater 1, an alarm function on/off switch 9, and a volume 17 for setting the temperature during sleep are provided. There is.

In the above configuration, when the energization on/off switch 16 is turned on, preheating is started at a high temperature setting regardless of the user's preferred sleeping temperature set by the temperature setting means 4 in advance.

After that, when the user goes to bed and turns on the alarm function on/off switch 9 for waking up, the control means 7 controls the amount of electricity supplied to the electric heater 1 so that the temperature is switched to the desired sleep temperature set by the user in advance. Control automatically.

Therefore, the user does not have to take the trouble of resetting the temperature when going to bed, and there is no inconvenience such as forgetting to switch to the appropriate temperature setting and falling asleep, and waking up in the middle of sleep due to the heat. You can sleep in comfortable conditions. Further, after being woken up by the alarm, if the alarm function on/off switch 9 is turned off, the power to the electric heater 1 is automatically turned off, so there is no chance of forgetting to turn off the power. For most users, setting and canceling alarms has become a daily routine.
This behavior is specific to sleep behavior. Therefore, there is no sense of inconvenience, and since the device configuration is based on an on/off switch, the operation is reliable and has very excellent effects.

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

i) The amount of electricity applied to the heater is changed in conjunction with the setting and cancellation of the wake-up alarm, so when preheating after starting operation, the blanket is quickly heated at a high temperature setting, and the blanket is heated quickly when the user goes to bed. If you set an alarm, the temperature will automatically change to a temperature suitable for sleeping. Also, the power is turned off by canceling the alarm when you wake up. Therefore, the user does not have to worry about resetting the temperature setting when going to bed, and at the same time, the user does not forget to switch to the appropriate temperature setting and fall asleep and wake up in the middle of sleep due to the heat, making it comfortable. In addition to being able to sleep while
There is no need to forget to turn off the power after waking up, and it is highly energy efficient.

■) Setting and canceling the alarm becomes a habit for most users and is unique to their behavior during sleep, so it can be used without any bothersome feeling of alarm.

11) Since the setting temperature is changed using a switch, operation is reliable.
