Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a gas appliance having a piezoelectric ignition device.

(b) Prior art A well-known piezoelectric element collides with a hammer to generate a high voltage that generates a spark, which ignites a burner.In particular, by pushing the operating knob in the axial direction, If a device that causes a hammer to collide with a piezoelectric element is placed on the front of the device in such a way that the operating knob is pressed in a substantially horizontal direction, there is a problem in that the device tends to fall backwards due to the pushing operation of the operating knob. .

(c) Purpose of the invention The purpose of the invention is to prevent the movement of the instrument due to the pushing operation of the operating knob.

(d) Structure of the invention The structure of the invention is that the operating knob of the piezoelectric igniter, which causes a hammer to collide with a piezoelectric element by pushing in the axial direction, is placed on the front of the gas appliance so as to push it toward the appliance. In the device, a grip with a finger groove is located on the instrument side of the operating knob and is fixed to the instrument body, so that the operating knob can be pushed and operated easily.

(E) Embodiment First, an embodiment of the present invention will be explained based on FIG. Combustion chamber 3 with open front and top surfaces
It forms a compartment. In addition, a well-known surface combustion type ceramic plate 4 is arranged in the inner part of this combustion chamber with its combustion surface 5 facing diagonally upward, and a guard 7 is attached to the upper surface of the combustion chamber 3 and the front opening 6. are doing.

Further, a knob 8 for controlling the fuel supply to the gas burner having the ceramic plate 4 by rotational operation is provided at a suitable position on the operation panel 2, and a knob 8 for igniting the gas burner is provided below the knob. An ignition device 9 is provided. As shown in FIG. 2, this igniter has an operating knob 10 that is pushed in the axial direction and is arranged on the operating panel 2 so that it can be pushed toward the main body 11 of the stove 1. On the operation panel 2 side of 10, there is a hook groove 12 for coaxially hooking a finger to the operation knob 10.
A grip 13 made of resin or the like is integrally fixed to the panel 2.

Furthermore, the main body 14 of the ignition device 9 has an operation panel 2.
For example, as shown in FIG. 3, this includes a cap-shaped outer case 16 that houses a piezoelectric element 15 at the bottom, and a cap-shaped outer case 16 that is slidably inserted into an opening at one end of the outer case and has an internal structure. It is mainly composed of a sliding tube 18 housing a hammer 17 that collides with the piezoelectric element 15 by the elasticity of a spring, and a pin 19 of the hammer 17 faces each sliding tube and outer case 16. The fitting grooves 20 and 21 are bored and the hammer 17 is configured to collide with the piezoelectric element 15 when the sliding tube 18 is inserted into the outer case 16 by a predetermined amount.

The sliding tube 18 is interlocked with the operation knob 10 when it is pressed, and during this pressing operation, for example, the index finger and ring finger are hooked into the hook groove 12 of the grip 13, and the grip is held between them, and the operation knob is operated with the thumb. By pressing 10, the ignition operation can be easily performed without applying force to push the stove body 11 backward.

(F) Effects of the invention With the configuration of the invention described above, the push operation of the operating knob can be easily operated without applying the pushing force to the instrument body, and the addition of simple parts improves usability.
