Description

[Detailed description of the invention] The present invention relates to a cooker with a lid, in which the lid pivots around the rear of the cooker body equipped with a gas burner between an upright position where it is retracted from above the gas burner and a horizontal position where it covers the gas burner. This invention relates to a cooking device with a lid that can be used for cooking.

Traditionally, this type of cooker was made, for example, in the 1970s.
−53218 is known. According to this, the lid functions as a cover for the gas burner when the cooker is not in use, and as a back guard when in use, and the igniter does not need to operate when the lid is closed when the cooker is not in use. However, although the ignition system will not operate if the lid is closed, if the gas valve is opened by mistake, raw gas will leak, creating a dangerous situation and requiring a safe shut-off configuration.

The present invention aims to eliminate these inconveniences, and will be explained in detail below with reference to the embodiments shown in the drawings. 1 is a cooking device, and 2 is a gas burner (not shown) on the top of the cooking device 1. ) and an upright position (second position) that is removed from above the gas burner.
The lid rotates at the rear fulcrum 8
It is rotatably supported.

Reference numeral 3 denotes an NO (normally open) switch, which is controlled to open and close by the lid 2, and is closed when the lid 2 is in the upright position where the top of the gas burner is open, and is opened when the lid 2 is in the horizontal position where it covers the gas burner.

4 is a power supply, 5 is a knob, and 7 is a capacity switching knob.

6 is a pressure adsorption type solenoid valve, and the valve 6A is a spring 6.
The valve 6A is energized to be closed at all times by the valve 6B, and the spring 6 of the valve 6A is energized by the electromagnet 10 and the knob 5.
When the pressure is applied against pressure B, the valve 6A is attracted by the electromagnet 10 and held open.

While the valve 6A is held open, the gas inlet 6''
The gas entering from the gas inlet 6'' is supplied to the gas burner (not shown) through the gas inlet 6''.

Reference numeral 9 denotes a detection operating rod which detects whether the lid 2 is in an upright position or a horizontal position and opens and closes the switch 3, and is energized by a spring or the like.

Although the power switch 3 is a normally open switch in the embodiment, it is not limited to this as the opening/closing operation of the lid can be changed by an appropriate coordination mechanism.

To explain the operation here, in the horizontal position with the lid 2 closed, the switch 3 is opened via the detection rod 9 and the power to the electromagnet 10 of the pressure adsorption type solenoid valve 6 is cut off. 6A closes the gas passage by a spring 6B. Here, even if the knob 5 is pressed, the pressure adsorption type solenoid valve 6 is not held open. On the other hand, when the lid 2 is opened, the switch 3 closes and the attraction circuit to the electromagnet 10 is closed, energizing the electromagnet 10. However, the gas is cut off unless the knob 5 is pressed, and the valve opens only when the knob 5 is pressed. be done.

As described above, according to the present invention, the power to the electromagnet 10 of the pressure adsorption type solenoid valve 6 is cut off by closing the lid 2, and even if the knob 5 is pressed, the spring 6B valve 6A due to the return force of
It is safe because the valve is opened and the valve is not held open, and the valve can be held open only when the electromagnet 10 is energized by opening the lid 2, but the valve is not opened by pressing the knob 5. Compared to a structure in which the valve is never opened and gas flows only when the lid of the cooker is opened, explosion accidents due to gas leaks can be prevented, making the cooker even safer. It has the effect of obtaining.

Claims (1)

[Scope of utility model registration request] In a cooking appliance with a lid, the lid can be rotated using the rear part of the cooking appliance equipped with a gas burner as a fulcrum between an upright position in which the lid is retracted from above the gas burner and a horizontal position in which the lid covers the gas burner. The gas supply path to the gas burner is opened and closed by closing the valve using a spring biased by the operating shaft of the knob, and the valve is opened by resisting the spring biased by pressing the knob. A lid with a lid characterized in that the suction piece is press-adsorbed by an electromagnet using a pressure-adsorption type solenoid valve, and the suction circuit of the solenoid valve is closed when the lid is opened via a switch that is linked to the opening and closing of the lid.
