Description

A valve structure in use with cooktop

The present invention relates to a channel structure of a cooktop valve, and more particularly, to a channel structure of a cooktop valve having an ignition function, a leakage prevention function, and a flow control function of a cooktop gas range.

Since the conventional cooktop gas range valve has to be installed in a space about the thickness of the sink, the valve operating portion is located at the upper portion and the gas inlet has to be installed at the front portion.

Such a conventional cooktop gas range valve has a structure in which a flow of gas flows through a plug, which is a part for opening the gas directly from the gas inlet of the main body, through a safety device (MPU), and then flows to a gas burner .

A problem with such a conventional cooktop gas range valve structure is that there is a fear that moisture may penetrate between the main body and the plug.

Moisture penetration into the main body can cause problems due to corrosion.

On the other hand, the conventional valve has the structure as shown in Fig.

1, the gas flow of the conventional cooktop valve is formed by a plug 3 which is engaged with the shaft when the combustion gas enters the main body 1 inlet 101 and the knob shaft 2 is rotated for ignition, The gas passes through the inside of the plug 104 and flows to the inlet 105 of the safety device 4 while the gas hole 102 of the plug coincides with the gas hole 103 of the main body.

At the same time when the valve is operated, the safety device is opened by the cam 5, and when the gas passage is opened, the gas passes through the gas outlet 106 of the sub-body 6 and flows to the burner. When the safety device is operated due to overheating, and when the cooking is finished and the valve is closed, the supply of gas to the burner is stopped and the combustion gas is eliminated in the valve. However, The combustion gas remains always to the main body gas hole 1 (103).

In other words, since the conventional cooktop valve is a structure in which the combustion gas flows from the gas inlet 101 of the main body 1 directly to the plug 3 as shown in Fig. 1, the safety device operates or the valve is closed The combustion gas remains at all times to the main body gas inlet 101 and the main body gas hole 103, so that moisture penetrates into the main body and the tab portion of the plug, or wear of the taper due to long- In case of a minute gap, not only the rotation becomes stiff but also gas leakage may occur.

As described above, in the conventional cooktop gas range valve, when there is a minute clearance due to wear due to repeated use, there is a possibility that the gas may leak even when the valve is closed.

In order to overcome the problems of the prior art as described above, the present invention has been devised to overcome the above-mentioned problems of the prior art, and it is an object of the present invention to provide a gas- And it is an object of the present invention to provide a channel structure of a cooktop valve in which there is no fear of gas leakage when the main valve is in a closed state.

In order to solve the above-described problems, the present invention provides a fuel cell system including a main body 10 having an inlet 1010 into which a combustion gas is injected while a safety device 40 is provided therein; A central passage (1120) formed in the main body (10) to form a flow path for the combustion gas; A gas passage 1080 communicating with the central passage 1120; A knob shaft 20 provided on the main body 10 to open and close the safety device 40; When the knob shaft 20 opens the safety device 40, the combustion gas is injected into the inlet 1010 and the gas outlet 1110 of the main body 10 through the safety device 40 ) Of the cooktop valve.

The main body 10 includes a channel structure for a cooktop valve in which a gasket 70 and a lower cover 80 are sealed at a lower end.

And a partition wall separating the central passage 1120 and the gas passage 1080 from each other.

The present invention as described above has the following effects.

First, even if there is a risk of gas leaking through the minute gap between the main body and the plug in the closed state of the valve, if the safety device is closed by construction, it prevents the gas passage. Therefore, if the valve is closed, there is no possibility of gas leakage. There is a strength that can be used safely.

Second, when the flue gas flows into the main body inlet, it flows into the burner only through the safety device. Therefore, water penetrates into the main body and the taper portion of the plug, or a minute gas leakage occurs due to wear of the taper portion due to long- Even if the fuse cock is not closed, the safety device blocks the gas passage, which is advantageous in that it can be used safely in the event of gas leakage.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In this process, the thicknesses of the lines and the sizes of the components shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of functions in the present invention, and this may vary depending on the intentions or customs of the user, the operator, and the like. Therefore, the definitions of these terms should be described based on the contents throughout this specification.

The main body 1000 is a cooktop valve unit.

The combustion gas flows from the main body inlet 1010 to the main body first gas passage 1080 through the second gas passage 1090 of the main body 10 as shown in FIGS. Reaches the entrance 1050.

Simultaneously, when the knob shaft 20 is depressed, the spindle 90 presses the cam 50 and the cam 50 simultaneously presses the safety device 40, thereby opening the gas passage.

The combustion gas escapes to the safety device gas outlet 1070 and reaches the central passage 1120 of the main body.

When the knob shaft 20 is rotated, the spindle 90 rotates so that the plug 30 rotates so that the plug gas hole 1020 and the main body gas hole 1100 are aligned with each other, The main body gas outlet 1170 is communicated and fluid communication becomes possible.

At this time, the combustion gas can be finally supplied to the burner through the main body gas outlet 1110.

When the valve is closed to a closed state, such as overheating or forced valve lock, the safety device blocks the gas outlet and the combustion gas is no longer supplied to the main body 10 and the plug. It does not exist.

The main body 10 is a gas passage and has a structure in which the gasket 70 and the lower cover 80 are sealed with screws at the lower end of the main body 10 so that the combustion gas flows smoothly and does not leak to the outside.

The central passage 1120 of the main body 10 and the main body gas passage 1080 are formed as separate walls so that the combustion gas flows to the central passage 1120 of the main body only through the safety device.

When the combustion gas passes through the gas passage 1090 of the main body 10, the main body central passage 1120 is sealed by the gasket 70 so that the airtightness is maintained so as to prevent the fluid from entering and exiting.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It will be understood that the present invention can be changed.
