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 is aimed at solving these drawbacks, and will be described in detail below with reference to the embodiment shown in the drawings.In the perspective view of FIG. It is a lid that covers the gas burner 10. 4 is an operation knob for the press opening/closing valve 8;
is a capacity switching knob that controls the gas flow rate through the bypass path, etc.

FIG. 2 is a partial side view of the main part of the embodiment of the present invention, showing the state in which the lid 2 is closed, and the lid 2 has a fulcrum 12 at at least one end of the rear part and is moved to a horizontal position 2B via a link mechanism. The switch 3 can be freely rotated to the upright position 2A, and the switch 3 can be opened and closed by a part of the link. Reference numeral 5 denotes a gas stop valve provided in a gas supply pipe 6 for supplying gas to the gas burner 10, which may be a solenoid valve, and is opened and closed by opening and closing the lid 2 to allow gas to pass through. In this embodiment, a solenoid valve is shown as the gas stop valve, and when the lid 2 is opened, the switch 3 is closed and opened. FIG. 3 shows the upright position 2A with the lid 2 open, with the switch 3 closed and the gas stop valve 5 open. Switch 3 is a NO (normally open) switch. FIG. 4 is a partial sectional view of another embodiment, in which the switch 3 is provided inside the cooker 1 and the lid 2 is
is supported by a fulcrum 12 and rotates. Reference numeral 14 denotes a detection lever for detecting opening/closing of the lid 2, and is biased by a spring 13.

FIG. 5 is a gas circuit diagram, in which a pressure on-off valve 8 is provided in series in the gas supply pipe 6 of the gas burner 10 outside the gas stop valve 5. FIG. 6 is an electrical diagram, in which a pressure-adsorption type solenoid valve is shown as the pressure on-off valve 8, and 7 is a power source, which is connected to the coil of the solenoid valve as the gas stop valve 5 via the switch 3. The electromagnet 9 of the pressure adsorption type electromagnetic valve 8 serving as the on-off valve 8 is electrically connected to the electromagnet 9 . The press opening/closing valve 8 is operated by a return spring 8B to always close the valve 8A, and at the same time as the lid 2 is opened, the switch 3 is closed and the coil of the gas stop valve 5 and the electromagnet 9 are energized, and the knob 4 is pressed. When the valve 8A is pressed against the force of the return spring 8B, the valve 8A is opened and attracted, and when the switch 3 is opened by the closing operation of the lid 2 and the energization is stopped, the valve 8A does not lose its attraction force and the return spring 8B At the same time, the gas stop valve 5 is also closed to cut off the gas supply. 8C is gas inlet, 8
D is a gas outlet, and the gas flow rate can be changed by switching such as bypass using a capacity switching knob 11, and the gas is supplied to the gas burner 10.

Although a normally open switch is used in the configuration of the switch 3 in the embodiment, the opening/closing operation of the lid can be changed by an appropriate linkage configuration, so the configuration is not limited to this. Further, the knob 11 may be configured such that the gas amount can be easily changed by pushing or the like.

To explain the operation here, when the lid 2 is closed, the switch 3 is opened to cut off the power to the gas stop valve 5 and the electromagnet 9 of the pressure-adsorption type solenoid valve 8, and the valve is double closed to prevent gas leakage. In addition to ensuring greater safety, even if the lid 2 is opened, the gas is shut off unless the knob 4 is operated.

As described above, according to the present invention, the lid has a horizontal position that covers the gas burner and a lid that is set in an upright position that is retracted from the horizontal position, so that when the cooker is not in use, the gas burner is not exposed and the appearance is maintained, and when the cooker is in use, the lid acts as a back guard. As a result, there is no dirt on walls, etc.

Furthermore, when the lid is closed in the horizontal position, the gas supply pipe is closed by a double valve body, so there is no gas leakage when the lid is closed, ensuring safety, and the gas stop valve is closed even when the lid is opened. Although the press opening/closing valve opens, it does not open immediately, but opens only after the valve opening operation, so it has the effect of enhancing a good feeling of use during use.
