Description

Switch for ovens and gas burners.

This invention relates to the unit of switching for furnaces and gas burners, which activates and deactivates a spark generator, which works in sync with the gas valve that is installed in it and that activates the spark generator providing electrical contact when the gas valve broken in the direction of gas opening, but returns to the original position, without activating the gas generator, when the gas valve rotates in the closing direction of the gas.

Our invention is based on the principle that in the direction of gas opening the switch allows the ignition by activating the spark generator by contacting the inside the terminal. On the other hand, in the closing direction of the gas, the switch returns to the original position, without allowing the ignition, deactivating the spark generator by not allowing the contact inside the terminal.

The current state of the art

With push-button switches, when ignition occurs, if the gas valve is pressed while the gas valve rotates in the gas closing direction, there is the risk of ignition, by mistake or accidentally, of the dispersed gas. However, with our invention, since there is no contact electric in the gas closing direction, the risk of unwanted ignition of gas.

With push-button switches, when press the gas valve (push button), the terminals are contacted of the cam. With rotary type switches, you can contact the terminals both in the opening address and in The gas closing direction.

The switch for ovens and gas burners that has been mentioned provides electrical contact only in the gas opening direction. In the gas closing direction no There is electrical contact. In the rotary type switch, which It works similarly, switching is allowed through the cam hammer system. With our invention, the switching is obtained only through the terminals by means of the wavy section of the long terminal, without using the hammer.

Both the terminals, which are the basis of the switching function, such as a plastic mechanism that drives The terminals have a unique and new structure. When the gas valve used in ovens or burners is turned on the gas opening direction, the cam (2) of our switch, which is manufactured according to the gas valve and installed in the same (8), begins to rotate.

The plastic mechanism (6) of the cam pushes the long terminal (3) to the short terminal (4) through the corrugated mechanism (7) of the long terminal (3) pushing the section corrugated (7) of the long terminal.

As a consequence of this pushing force, the long terminal (3) contacts the short terminal (4) so that electrical contact occurs. When there is electrical contact, the spark generator, connected to the switch, ignition begins and the gas burns.

When the end of the cam mechanism (6) reaches the end of ignition angle, set as necessary, as the pressure of the wavy mechanism increases (7) of the long terminal, the long terminal returns to the normal position and The electrical contact between the terminals is interrupted. When interrupts the electrical contact, the spark generator, connected to the switch, stops the ignition.

When the gas valve is turned in the direction closing, the corrugated mechanism (7) of the long terminal (3) prevents the long terminal (3) contact the short terminal (4) separating the terminals. Since there is no electrical contact, the spark generator connected to the switch does not perform the ignition.

The mechanism (6) is beveled in one direction similar to the wavy section (7) of the long terminal and according to the direction of rotation of the terminal, it is guaranteed that it is above or below the mechanism. Mechanism length (6) can be adjusted (the end and start angles of the ignition) according to customer needs.

The upper and lower sections (8) of the Cam installed in the gas valve can be adjusted according to the type Valve and according to customer needs. The diameter of the Cam installed in the gas valve can be adjusted according to the customer needs. As regards the other angles of the gas valve, the cam can move freely and there is no electrical contact. The switch can be operated within a quite small area with a height of 4.4 mm.
