Abstract

PURPOSE:To cause a user to understand easily that an energization for a heater is terminated by a method wherein an occurrence of an earthquake is displayed by a controlling means for terminating an energization of a heating means when the earthquake is detected, an earthquake displaying means informing an occurrence of the earthquake through a liquid crystal and a liquid crystal driving means. CONSTITUTION:When an earthquake occurs during heating and cooking operation, an earthquake sensing means 15 may detect this state. A controlling means 12 may receive a condition when the earthquake sensing means 15 detects the earthquake, an energization for a relay coil 11c is terminated, and then a relay contact point 11b is released. With this arrangement, an energization for a heater 11a is terminated. In this way, when an earthquake occurs, since an energization for the heating means 11 is automatically terminated, it is safe. When a controlling signal for terminating an energization for the heater 11a, the controlling means 12 may also output a signal to a liquid crystal driving means 14. The liquid crystal driving means 14 may drive an earthquake displaying means 13, display that a cause for terminating the energization for the heater 11a consists in an occurrence of the earthquake and inform it to the user.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric shoe heater for general household use;
It is related to.

BACKGROUND OF THE INVENTION Conventional electric shoe heaters have not been equipped with earthquake detection means. In addition, kerosene stoves stopped burning when they detected a fall or an earthquake.

Problems to be Solved by the Invention If an earthquake occurs when using an electric shoe heater, if the power to the heater is not immediately stopped,
This is extremely dangerous and can cause a fire. However, with conventional electric shoe heaters, this work must be performed by the user. In addition, in the case of electric shoe heaters, there are various safety devices. For example, just like with kerosene heaters, it is not possible to simply turn off the power to the heater when an earthquake is detected. There was a problem in that even if you looked at the heater, you couldn't tell what caused it to stop, so you couldn't take appropriate measures.

The present invention solves these problems.When an earthquake occurs, the power to the heater is immediately stopped, and then the occurrence of an earthquake is displayed, and the user is informed that the power to the heater will be turned off when an earthquake occurs. The purpose of this is to quickly confirm that the system has stopped.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a control means for stopping power supply to the heating means when the earthquake detection means detects the occurrence of an earthquake, and a control means for stopping the electricity supply to the heating means when the earthquake detection means detects an earthquake. The device is configured to display the occurrence of an earthquake in an easy-to-understand manner to the user, using an earthquake display means to notify the user of the occurrence of an earthquake by means of a liquid crystal display, and a liquid crystal drive means that controls the display of the earthquake display means. It is.

Operation According to the above configuration, when an earthquake occurs, it is detected by the earthquake detection means, and the occurrence of an earthquake can be displayed by the earthquake display means and the liquid crystal drive means that controls the display of the earthquake display means. Therefore, even if the user leaves the area while using the electric shoe heater, the electricity to the heating means stops due to an earthquake, and then returns,
The earthquake display means allows one to see at a glance that the cause of the heating stop of the electric shoe heater is an earthquake.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 is a block diagram showing the configuration of an electric footwear heater according to an embodiment of the present invention, and FIG. 2 is a circuit diagram of the same electric footwear heater. In FIGS. 1 and 2, 11 is a heating means for heating a cooking container such as a kettle or a pot, 12 is a control means for controlling the heating means 11, 13 is an earthquake display means consisting of a liquid crystal display element, and 14 is an earthquake display device. A liquid crystal driving means drives the display means 13, and an earthquake detecting means 15 detects the occurrence of an earthquake from vibrations caused by the earthquake.

Further, in FIG. 2, 16 is a commercial power source, 17 is a liquid crystal display panel, and the earthquake display means 13 is constructed in this liquid crystal display panel 17.

The heating means 11 includes a heating heater 11a and a relay contact 1.
1b and a relay coil 110, and the relay coil 11C is energized and controlled by the control means 12, and controls the opening and closing of the relay contact 11b. As a result, current flows from the commercial power source 16 to the heating heater 11B, so that the heating heater 11a is controlled to be energized and a cooking operation is performed. If an earthquake occurs during this cooking, the earthquake detection means 15 detects this. Control means 1
2, when the earthquake detection means 16 detects an earthquake, it stops energizing the relay coil 'IIC and releases the relay connection q 11b. As a result, heating heater 1
Power supply to 1a is stopped. When an earthquake occurs in this way, the power to the heating means 11 is automatically stopped, so
It's safe. The control means 12 also includes a heating heater 11a.
When outputting a control signal to stop energization, a signal is also output to the liquid crystal driving means 14. The liquid crystal driving means 14 accordingly drives the earthquake display means 13 to display and inform the user that the reason for stopping the power supply to the heating heater 11a is the occurrence of an earthquake. The user is
By displaying "Earthquake Occurrence" on the earthquake display means 13, it is possible to know the occurrence of an earthquake without being present at the time of occurrence.

As is clear from the description of the above embodiments, according to the present invention, when an earthquake occurs, the earthquake display means composed of liquid crystal displays the occurrence of an earthquake in a display format that is easy for the user to understand. As a result, even if the electric heater is stopped due to an earthquake, the condition can be easily known even by a third party.
It is possible to provide an electric heating heater that can take appropriate measures when the device is restored, and since this display uses a liquid crystal display element, the power consumption by the display can be minimized, resulting in Even if the power supply to the control circuit is cut off, the display can be continued with a small amount of power backup.
