Description

Safety apparatus of gas valve

The present invention relates to a safety device of a gas valve, and in detail, to supply or shut off the gas to a gas range (hereinafter referred to as a 'cooking utensil') that uses gas as fuel in each home or restaurant, etc. In order to cook by installing a valve opening gear in the secondary valve installed in the valve and installing a rectifier, a timer, a deceleration part, and a motor by an electric circuit configuration to operate the valve opening gear, the cooking time is set by a timer. When the secondary valve is 'open', gas is supplied and cooked. When the cooking time is over, the timer is stopped and the secondary valve is 'closed' automatically by the mechanical driving of the motor by the electric circuit so that the gas supply is cut off. Therefore, it is possible to prevent the accident of fire caused by fire in advance.

As described above, the secondary valve 200 installed to supply or shut off gas to the cooking utensil in each conventional home or restaurant is connected to the gas hose 500 of the input side of the cooking utensil GR. It is installed connected to the output side of the gas supply pipe 400, if the internal opening and closing structure of the secondary valve 200 is a ball valve type, the valve opening and closing handle 100 installed to the outside of the ball valve is operated horizontally by artificial manipulation When the secondary valve 200 is closed and gas supply is cut off and the valve opening / closing knob 8 is operated vertically, the secondary valve 200 is configured to be “open” to supply gas.

Therefore, the installation position of the secondary valve 200 is connected to the end of the gas supply pipe 400 between the meter 600, the primary valve 700 is installed and the cooking utensils GR, the third valve 800 is installed. The cooking apparatus GR, which is installed at the output side of the reducer 300 and is connected to the secondary valve 200 and the gas hose 500, is provided with a gas safety protection device. The third valve 800 installed in GR) is operated to ignite or extinguish gas.

Therefore, if the cooking is to be operated in the state shown in Figures 4 and 5 by manipulating the valve opening and closing handle 100 vertically by the artificial operation, the secondary valve 200 is 'open' and gas is supplied to the gas range (GR The food is cooked by igniting the gas by operating the tertiary valve 800), and after the cooking is finished, the third valve 800 of the gas range GR is operated to extinguish the fire. However, in order to prepare for gas safety accidents, the secondary valve 200 is normally closed after cooking. At this time, the secondary valve 200 is artificially operated horizontally, and the inconvenience of shutting off the gas supply was accompanied. In particular, while cooking, watching TV or talking with a visitor who has suddenly come to work, it is not only the case that they burn food while ruining other things, but also forget to cook when they are not good. Most housewives are actually experiencing the case of leaving cooking utensils for work.

In addition, even if the above cases, such as water, the water disappears and the container is overheated (this also happens when the housewife or family is in the house), but there is a high risk of fire when going out In addition, foods such as grease in containers cause fire and are reported in the press. Therefore, there is no hassle in use and handling operations that always pay attention to safety, as well as accidental injury or damage to property due to fire. There were various problems such as causing a safety accident.

The present invention artificially operates the valve opening and closing handle vertically as in the case of 'open' the secondary valve installed to supply or cut off gas to cookware used in each conventional home or restaurant as described above, When the secondary valve is 'closed' and 'closed', when the cooking time set by the timer is over, the timer stops and the secondary valve is automatically closed by the mechanical operation of the motor by the electric circuit. The secondary valve is 'open' during cooking to supply gas, and when the cooking is finished, the secondary valve is automatically 'closed' to cut off the gas supply, thus preventing accidents.

When showing a perspective view of the state described in detail according to the accompanying drawings the configuration of the present invention as follows.

As shown in FIGS. 4 and 5, a primary valve 700 is installed in the main gas supply pipe MG as an input side of the meter 600 and is connected to the output gas supply pipe 400 of the meter 600. The secondary valve 200 is installed on the output side of the reducer 300 and the valve opening / closing handle 100 is installed in front of the secondary valve 200 and the valve opening / closing handle 100 is artificially horizontally or vertically installed. Gas valve devices that are operated to supply or shut off gas are known.

According to the configuration of the present invention, as shown in FIG. 2, when the valve opening and closing gear 5 is installed on the valve shaft 6 of the secondary valve 200, and the motor 1 is driven, the motive gear mounted on the motor shaft ( 3) is driven so that the secondary valve 200 is 'close' by the rotation of the valve opening and closing gear (5) meshing with the slave gear (3a) driven through the reduction unit (4). When the secondary valve 200 rotates to the 'close' position, the B contact limit switch 9 is operated by the limit operation lever 7 formed on one side of the circumferential surface of the valve opening / closing gear 5 to open the open circuit. circuit) to stop the driving of the motor 1.

The driving condition of the motor 1 is that when the setting time of the A contact limit switch 10 installed in the timer 12 ends, the scale indicating portion 14a of the time setting knob 14 is set to '0' of the cooking time scale 16a. The position control lever 7a operates the A contact limit switch 10 to become a closed circuit at the position ', and thus the motor 1 is configured to drive.

At this time, when the valve opening / closing handle 8 is in the 'open' position, the motor 1 is driven until the valve opening / closing handle (8) is closed, thereby closing the secondary valve 200. It is configured to be '.

The timer 12 continues to operate by mechanical driving until the B contact limit switch 10 is opened, and is configured to stop the timer 12 by a stopper 18.

In addition, the limit operation lever 7a operates the A contact limit switch 11 about 5 minutes before the end of the cooking time in order to inform that the cooking time is finished. It is configured to determine whether to extend the cooking time or the first adjusted time is sufficient, and if the cooker does not hear the alarm sound of the alarm 13, the timer 12 continues to operate the A contact limit switch ( 11 is set to an open circuit state to stop the motor 1, and the limit operation lever 7a of the timer 12 is configured to rotate by stopping to the stopper 18 position.

In addition, since the motor 1 uses a small DC motor, the rectifier 2 is installed so that the primary power source can be used for 220V.

As shown in FIG. 2, the substrate 17 is configured to be fixed to the gas supply pipe 400 and the secondary valve 200 with a clamp 400b.

As shown in FIG. 3, the cover 16 forms an exposure hole 16c through which the time setting knob 14 is exposed and an exposure hole 16b through which the valve opening / closing handle 8 is exposed. On one side, the cooking time scale 16a is displayed, and the horizontal position of the exposure hole 16b is marked with the secondary valve 200 'Close', and the vertical position is marked with the secondary valve 200 'Open'. It is comprised so that the board | substrate 17 may be covered and fixed.

In the figure, reference numeral 400a indicates a clamp for fixing the gas supply pipe 400 and 500a indicates a clamp for fixing the gas hose 500.

The present invention configured as described above is to be used in the 'A' portion as shown in Figure 4 when described in detail the operation as follows.

When the food is to be cooked, the plug 15 is connected to a power source in the state shown in FIG. 1, and then the valve opening / closing knob 8 is operated vertically so that the secondary valve 200 is 'open' so that the gas is released. Since it is supplied, the process of cooking by operating the tertiary valve 800 of the cooking appliance GR is the same as in the related art.

However, the present invention operates the valve opening / closing handle 8 vertically to operate the tertiary valve 800 of the cooking appliance GR in a state in which the secondary valve 200 is 'open' to start cooking by igniting gas. In this case, the B contact limit switch 9 is in a closed circuit state and the A contact limit switch 11 is in an open circuit state due to the release of the limit operation lever 7. Is not driven, and if the cooking time is set so that the scale indicating portion 14a of the time setting knob 14 matches the cooking time scale 16a according to the type of cooking, the A contact limit switch is released due to the deviation of the limit operation lever 7a. 10) 11 is in an open circuit state, and the timer 12 is driven to start cooking, so other work required may be performed.

5 minutes before the end of the cooking time while the food is being cooked, the limit operation lever 7a operates the B contact limit switch 11 to be in a closed loop state, so that the alarm 13 sounds and checks the cooking state.

If the cooking time is set according to the type of food, and the cooking time is needed, the cooking time can be extended as much as necessary by operating the time setting knob (14). The third valve 800 may be operated to extinguish a gas fire.

In addition, if the cooking time is required for the remaining time after the alarm 13 is sounded, if it is left as it is, the scale indicating portion 14a of the time setting knob 14 of the timer 12 goes to the '0' position of the cooking time scale 16a. The limit operation lever 7a operates the A contact limit switch 10 to be in the closed circuit state, while the B contact limit switch 9 is in the closed circuit state, so the motor 1 is driven and the motor When the driven gear 3a and the valve opening / closing gear 5 to be driven and rotated by the deceleration drive of the motive gear 3 and the driving reduction gear 4 by the driving of the first valve (2), the secondary valve ( Since 200 is closed and the limit operation lever 7 operates the B contact limit switch 9 to enter an open circuit, driving of the motor 1 is stopped.

As described above, when the secondary valve 200 is 'open', the valve opening / closing knob 8 is opened vertically by artificial manipulation as in the prior art, and the motor is opened when the cooking time of the timer 12 is set. By the mechanical drive by the driving of 1) it will be able to use the secondary valve 200 is automatically repeated 'Close' process.

If you want to continue cooking without setting the cooking time of the timer 12, artificially operate the valve opening / closing handle 8 vertically as in the prior art, and open the secondary valve 200 to open the cooking. On the other hand, after cooking is finished, the valve opening and closing handle 8 is artificially operated horizontally so that the secondary valve 200 may be used to 'close'.

The present invention according to the above process is the same as the secondary valve is' Open 'to cook by supplying gas by artificially operating the valve opening and closing handle vertically when cooking food, but the present invention is the secondary valve is' Open When the cooking time set by the timer is over, the secondary valve is 'closed' by the mechanical drive of the motor to shut off the gas supply, so the gas ignition valve of the cooker is 'open' after cooking. Can prevent accidental fire accidents caused by gas in advance even if you do other things during cooking or cooking time, and it can prevent human accidents or property damage in advance, and it is easy to use and handle, and wastes unnecessary gas more than cooking time. It will have economic effects such as reduction.
