Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a combustion appliance having an electronic control device, and in particular to a safety device thereof.

Conventional Technology In recent years, feather touch type gas stoves have been developed to improve the appearance and convenience of gas stoves. These can be started with a light feather touch switch on the operation panel, and an electronic control device with a built-in microcomputer drives the motor and controls the amount of gas burned.

Problems to be Solved by the Invention However, while this configuration of the feather touch switch is convenient because it can be started with just a light touch, for example, even if flammable materials such as paper are placed on the gas stove, There was a risk that a part of the body could accidentally touch the switch and activate it. In addition, in order to eliminate this problem, in the case of a device in which combustion is started only by operating multiple switches in a prescribed order, it is necessary to perform many operations each time it is used, which makes it less convenient. There was a problem that was missing.

The present invention solves the above problems and provides a safe and convenient combustion appliance.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a child lock device that can be used only after the prescribed operating order of the operation switch at the start of use, and also provides a child lock device that can be used only after the child lock is released. The present invention provides a combustion appliance equipped with a child lock release timer device which, when enabled, allows use for a certain period of time without performing the prescribed operation.

Effects With this configuration, the gas stove will not burn even if you accidentally touch the switch, and when you actually use it frequently, you can use it without having to perform many operations every time you start combustion. be able to.

Embodiment An embodiment of the present invention will be described below based on the drawings. FIG. 1 is an external view of the gas stove, FIG. 2 is a diagram illustrating its operation panel and structure, and FIG. 3 is an operational flow diagram. In Figures 1 and 2, 1
is a gas stove, 2 is a burner, 3 is an operation panel, 4
5 indicates a display lamp, 5 indicates an operation switch, and 6a to 6e indicate capacity changeover switches. Further, 7 is a motor cock provided in the gas passage to the burner 8, and 9 is an operation switch for operating the electronic control circuit 10, which operates in conjunction with the operation switch 5 and the capacity changeover switches 6a to 6e. A control circuit 10 controls the motor cock 7.

The operation of the gas stove configured in this way will be explained using FIG. 3. First, when the capacity changeover switch 6c (switch □3) is pressed, the child lock is removed by the electronic control circuit 10 and can be used thereafter. At the same time, a child lock release timer (not shown) starts, and the display lamp 4 lights up in green. Next, when the operation switch 5 is pressed, combustion starts. Although the combustion at this time is a large calorie burn, any desired capacity can be obtained by pressing the capacity changeover switches 6a to 6e. Also, while the child lock release timer is operating, combustion can be started even if these capacity changeover switches are suddenly pressed. If the operation switch 5 is pressed during combustion, combustion is stopped. If you want to burn it next time, you can burn it by pressing the operation switch 5 or any one of the capacity changeover switches 6a to 6e again while the release timer is operating. This child lock release timer is valid for about one hour, for example, but if you want to activate the child lock immediately after use, press the ability changeover switch 6c to activate the child lock.
The child lock release timer will stop after about one hour, but if you wish to continue releasing the child lock, you can press the ability changeover switch 6c again.
However, during combustion, combustion does not stop even if the child lock release timer stops. These operating sequences are preprogrammed in the microcomputer in the electronic control circuit 10, and are activated by these commands.

As mentioned above, the capacity changeover switch 6c at the start of use
The child lock device, which can be used for the first time by following the prescribed sequence of operations such as pressing , and then pressing the operation switch 5, not only increases safety, but once the child lock is released, the operation switch 5 can be pressed for about an hour. It is also convenient because it has a child lock release timer device that allows you to burn it with just one operation. Furthermore, it is easy to use because it can be seen at a glance whether or not the child lock is currently engaged by the display device consisting of the display lamp 4.

Although this embodiment has been described using a gas stove as an example, the present invention can also be applied to a gas fan heater, water heater, etc.

Effects of the Invention As described above, the present invention includes a child lock device that can be used in accordance with the predetermined operating order of the operation switch, so that there is no possibility that a part of the body may accidentally touch the switch and start combustion. Not only is it very safe, but it also has a child lock release timer, so if you use it frequently, you don't need to do many operations every time you start combustion, making it convenient.
