Abstract

PURPOSE:To provide an leaving-ON state preventing device capable of preventing a heating apparatus utilizing electric power or city gas as its power source from being used in an unmanned state for a long time. CONSTITUTION:This device is provided with a human body sensing means 2 for sensing a human body existing in a room, a passage time measuring means 3 for measuring a time elapased from the exit of the person from the room, a stop time setting means 4 for setting up a time from the exist of the person from the room up to the stop of the heating apparatus, a judging means 5 for judging control based upon respective outputs from the means 2 to 4, and a control means 8 for controlling electric power/city gas to be the power source of the heating apparatus. When a heating body detecting means 6 detects a heating body from the output of a phyroelectric sensor 7 for detecting the heating body arranged in the room, the means 8 for controlling the power supply/city gas is started and a power supply braker 9 and a city gas valve 10 are controlled to stop the heating apparatus.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing a user from forgetting to turn off a heat generating appliance, which is used in a room in a home or an office building where a heat generating appliance powered by electricity or gas is installed.

0002

[Background Art] In recent years, many cooking appliances, gas appliances, etc. have been installed in homes and buildings, and these appliances are connected to automatic monitoring and control devices and central monitoring systems to perform disaster prevention management. is required.

[0003] Conventionally, this type of device for preventing users from forgetting to turn off heat-generating appliances such as electric and gas appliances has generally had a configuration in which a timer is installed and the appliance is stopped after a certain period of time has elapsed.

[0004] With the above configuration, there are cases where the user forgets to set the timer, so the device for preventing forgetting to turn it off is
It means that it is not functioning properly.

[0005]

[Problems to be Solved by the Invention] There has been no effective means for preventing devices from forgetting to turn off heat-generating appliances such as electric and gas appliances in the past. In addition, if a fire occurs due to forgetting to turn off a heat-generating appliance, the only way to report it is through a fire alarm, so it may be difficult to prevent a fire, or even if the appliance is left unused for a long time without causing an accident. There was a problem in that it lacked energy efficiency due to continuous use.

The present invention solves the above-mentioned problems, and includes a human body sensing means for sensing a human body in a living room, an elapsed time measuring means for measuring the elapsed time since a human leaves the living room, and a stop time setting means for setting the time from when the person leaves the room until the heat generating appliance is stopped; and a control decision based on the output of the human body sensing means, the output of the elapsed time measuring means, and the output of the stop time setting means. Forgetting to turn off a heat-generating appliance, which is equipped with a judgment means for determining the temperature, a heat-generating element detection means for detecting the heat emitted from the heat-generating appliance installed in the living room, and a control means for controlling the power source and gas that power the heat-generating appliance. The purpose is to provide a prevention device.

[0007]

[Means for Solving the Problems] In order to achieve the above objects, the present invention provides a human body sensing means for sensing a human body in a living room, and an elapsed time measuring means for measuring the elapsed time after the human leaves the living room. and stop time setting means for setting the time from when a person leaves the room to when the heat-generating appliance is stopped; the output of the human body sensing means; the output of the elapsed time measuring device; and the stop time setting. A judgment means for making a control judgment based on the output of the means, a heating element detection means for detecting heat emitted from a heating appliance installed in the living room, and a control means for controlling the power source and gas that are the motive power of the heating appliance. This device is designed to prevent users from forgetting to turn off heat-generating appliances.

[0008]

[Function] With the above-described configuration, the present invention can prevent fires and improve energy saving by preventing heat-generating devices from being used unattended for long periods in living rooms where heat-generating devices are installed. It is.

[0009]

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

As shown in the figure, a human body sensing means 2 constantly monitors the presence or absence of a human body in the living room based on the output of a human body sensing sensor 1 installed in the living room.

[0011] The elapsed time measuring means 3 for measuring the time elapsed since the person left the living room is the human body sensing means 2 described above.
It is determined that the person has left the room based on the output of ``No body reaction in the room,'' and the elapsed time is measured.

[0012] The stop time setting means 4 sets the time from when a person leaves the living room to when the heat generating appliance is stopped.

The determining means 5 stops the time measurement of the elapsed time measuring means 3 if the output of the human body sensing means 2 indicates "there is a human reaction in the living room" within the time input from the stop time setting means 4. Further, if the output of the human body sensing means 2 is "no human reaction in the room" within the time inputted from the stop time setting means 4, the heating element detecting means 6 is activated.

The heating element detection means 6 constantly monitors the presence or absence of a heating element in the living room based on the output of a pyroelectric sensor 7 that detects a heating element installed in the living room. The heating element detection means 6 activates the power supply and gas control means 8 when detecting a heating element.

The power supply 14 and gas 15 control means 8 controls the power supply breaker 9 and the gas valve 10 to operate the electric appliance 1.
2. Stop the gas appliance 13.

[0016] The above configuration prevents fires from being used unattended for long periods of time in living rooms in which heat generating appliances powered by electricity or gas are installed, thereby preventing fires and improving energy savings. can be done.

As described above, according to the device 11 for preventing forgetting to turn off a heat generating appliance according to an embodiment of the present invention, the heat generating appliance is used unattended for a long time in a living room in which a heat generating appliance powered by electricity or gas is installed. By preventing fires from occurring, it is possible to prevent fires and improve energy savings.

In the embodiment, as soon as the heating element detection means 6 detected a heating element, the power supply and gas control means 8 was started to control the power supply breaker 9 and the valve 10, but there was a case where the heating element was forgotten to be turned off. The prevention device 11 may output the output of the heating element detection means 6 to a central monitoring system, and the control of the power source 14 and the gas 15 may be determined by the central monitoring system.

[0019]

[Effects of the Invention] As is clear from the above embodiments, the present invention prevents the above-mentioned heating appliances from being used unattended for long periods of time in a living room in which a heating appliance powered by electricity or gas is installed. By doing so, it is possible to provide a device for preventing forgetting to turn off a heat generating appliance, which can prevent fires and improve energy saving.
