JP2002147767A - Foot warmer with sensor switch - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a foot warmer with a sensor switch capable of heating a heater and turning off a power source by automatically inputting a power source to a heater when a user enters the foot warmer and goes out of the foot warmer through provision of the heater of the electric foot warmer with the sensor switch. SOLUTION: By inserting an insertion plug 5 of a cord 3 in a receptacle, a current is fed to a sensor switch 2 and the sensor switch 2 holds a current. When a user 6 enters a foot warmer 4, the sensor switch 2 senses the user 6 and a current is fed to the heater 1 through a wiring 7. The heater 1 inputting a current is converted into a thermal heat. By discharging the thermal heat in the chamber of the foot warmer 4, the foot warmer 4 is warmed. When the user 6 goes out of the foot warmer 4, the sensing sensor switch 2 detects that no user 6 is present in the foot warmer and automatically turns off a power source.

Description

DETAILED DESCRIPTION OF THE INVENTION

[Technical field to which the invention pertains] In the present invention, when a sensor is connected to a heater of an electric kotatsu, when a person enters or exits the kotatsu, the sensor can detect and automatically turn on / off the power. It relates to a sensing sensor switch.

[Prior Art] A conventional electric kotatsu switch has to be used when a person operates the switch to turn on / off the power and use the switch. I used to keep the heater on because it was troublesome to switch off. Therefore, there is a drawback that electricity is consumed uneconomically, and there is a risk that a fire may occur due to overheating of the heater. Further, the conventional electric kotatsu switch has a drawback that the heater cannot be forgotten to be turned off. In addition, there is a disadvantage that a small child who cannot operate the switch, an elderly person, and a physically handicapped person cannot use the kotatsu by turning on or off the power.

[Problems to be Solved by the Invention] Therefore, forgetting to turn off the power, consuming a large amount of electricity, and the danger of causing a fire could not be solved by a conventional kotatsu switch. The present invention automatically switches on and off the heater without any human operation, eliminating forgetting to turn off the power, eliminating unnecessary consumption of electricity and the danger of heating the heater. It has been developed for the purpose of enabling small children, the elderly, and people with physical disabilities to use the electric kotatsu with peace of mind.

[Means for Solving the Problem] The structure will now be described. 1. A heater 1 is attached to the kotatsu 4 shown in FIG. 2. Attach the sensing sensor switch 2 to the kotatsu 4 in FIG. 3. Connect the sensor sensor switch 2 and heater 1 with the wiring 7 in FIG. 4. FIG. 1, the cord 3 with the plug 5 plugged into the sensor switch 2 is attached.

[Embodiment of the Invention] When the plug 5 of the cord 3 of FIG. 1 of the present invention is inserted into the outlet of the power supply, the current enters the sensor switch 2, and the sensor switch 2 suspends the current. , Fig. 2, Kotatsu 4 and person 6
Enters, the sensing sensor switch 2 knows the person 6 deeply,
The current is sent to the heater 1 through the wiring 7, and the heater 1 that has received the current converts the heat into heat, discharges the heat into the room of the kotatsu 4, and heats the kotatsu 4. Figure 3 and Kotatsu 4
When the person 6 exits, the sensing sensor switch 2 knows that the person 6 is not in the kotatsu and automatically turns off the power.

[Effects of the present invention] Therefore, since the human body plays the role of switch operation, even a small child, an elderly person, or a physically handicapped person who cannot perform the switch operation can use the kotatsu 4.
You can use the kotatsu by going in and out, turning the power on and off. Further, unlike a conventional kotatsu, there is no need to forget to turn off the power or to use the kotatsu while the power is kept on, so that power consumption can be saved and the economical effect can be greatly brought out. In FIG. 3, when the person 6 is not in the kotatsu 4, the heater 1 of the kotatsu 4
Is automatically cut off, so that there is no danger of a fire due to overheating of the heater 1, and great safety is created. Therefore, the user can turn on and off the power supply without operating the switch, thereby saving power consumption and using the kotatsu safely without fear of fire.

The present invention can be performed as follows: a. A sensor switch 2 is attached to one end of the heater 1 in FIG. B. Set the sensor of the kotatsu sensor sensor switch to low temperature when nobody is in the room, and make it to keep the kotatsu room warm. C, Fig. 5, changing the heating temperature of the kotatsu like a wave to make it warm, and when approaching the temperature 8 lower than the temperature 9 of the human body, the sensing sensor switch detects and turns on the heater 1
Make the power off. D. You can attach a sensor to the heater with kotatsu with fan.
