Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a fire power display structure for a gas igniter, and relates to a technique that enhances the appearance while giving the user a sense of security in the extinguished state.

[Background Art] Conventionally, in the fire power display structure of a gas ignition device, a reference position display such as a white line is drawn on the side of the operating button that is rotated, and a fire power strength display that displays the strength of the fire power is drawn on the operation panel side. If you draw an arc-shaped firepower strength display like this on the operation panel side, this firepower strength display will be noticeable, and the firepower strength display will make the entire kitchen look unified. There was a problem in that it was conspicuous and deteriorated the appearance. On the other hand, in recent years, an operation mode has been developed in which ignition and extinguishment are performed by pressing a round operation button, and firepower is adjusted by rotating the operation button. If a fire power strength display is provided in front of the operation button of the mold, the appearance will be similarly degraded, and the fire power strength display on the operation button side must be set to the strongest position when operated, relative to the reference position display provided on the operation panel side. The fire is extinguished by pressing the button in the operating position of the button, and when the fire is extinguished in the strongest state, the user must check that the reference position display and the strongest position of the fire strength display match. The problem was that people were concerned about the situation even though the fire had been extinguished.

[Purpose of the invention] The present invention was made in view of the above problem, and its purpose is to make the fire strength display formed on the operation button side invisible when the fire is extinguished. To provide a firepower display structure for a gas ignition device that improves the appearance in the state, that is, in the non-use state, and does not make a user feel uneasy.

[Disclosure of the invention] The present invention performs ignition and extinguishing operations by pressing the round operation button 1, and adjusts the firepower by rotating the operation button 1. This is a fire power display structure of a gas igniter that is in a combustion use state when the operation button 1 is protruded from the top of the screen, and is in a fire extinguishing state when the operation button 1 is close to the operation panel P. , is characterized in that a fire power strength display Z indicating the strength of fire power is provided along the circumferential direction on the outer circumferential surface of the operation button 1 portion that protrudes forward from the operation panel P in the combustion use state, and this With this configuration, the above object has been achieved. In other words, a reference position display Y indicating the reference operation position is formed on the operation panel P, and the intensity of the fire power is indicated along the circumferential direction on the outer circumferential surface of the operation button 1 portion that protrudes forward from the operation panel P in the combustion use state. By providing the firepower intensity display Z, operation button 1
In the extinguishing state, the firepower intensity display Z formed on the operation button 1 can be placed deep into the operation panel P, and the firepower intensity display Z formed on the operation button 1 can be placed in the depths of the operation panel P. The fire strength display Z can be hidden to enhance the appearance, and since the fire power strength display Z is hidden in the extinguished state, even if the operation button 1 is set to the high flame position in the extinguished state, the user cannot change it. It is designed so that you do not have to feel anxious about seeing a strong fire even when it is extinguished.
