Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer device used in gas stoves and other gas appliances that causes a gas valve built in the timer to open for a set time.

Conventionally, in this type of device, a timer cam connected to the timer shaft of the timer itself has a follower attached to the gas valve, and the rotation of the timer cam has been used to apply a set time response to the gas valve. However, in this case, the gas valve is subject to a predetermined opening determined by a timer cam, and this has the disadvantage that it cannot be adjusted to any desired opening.

An object of the present invention is to provide a device that eliminates such inconveniences, and in which a timer cam is connected to a timer shaft of a timer main body that has a built-in gas valve, and a follower that smells the gas valve is attached to the timer cam. In a type in which the gas valve is brought into contact with each other and the rotation of the timer cam causes the gas valve to open for a set time, the gas valve and the follower are urged toward the timer cam by a spring through a connector. The gas valve and the follower are connected to each other, and either one of the gas valve and the follower is screwed into the connector so as to be moved forward or backward as the connector rotates, so that the connector can be freely adjusted in rotation from the outside of the timer main body. It is characterized by the following.

Next, one example of implementing the present invention will be explained with reference to attached drawings.

In the drawings, reference numeral 1 indicates a timer main body that includes a timekeeping part 2 that houses a spring spring and other timekeeping parts on the upper and outer sides, and the timer main body 1 has a gas inlet 3 on the lower side and a gas inlet 3 on one side thereof, that is, the left side in the drawing. The gas valve 5 is provided with an outflow port 4 and has a built-in gas valve 5 that moves forward and backward to open and close the outflow port 4. Reference numeral 6 indicates a main timer shaft having a main dial 6a at the upper end protruding from the timekeeping section 2; 7 indicates a width timer shaft having a sub dial 7a at the upper end loosely connected to the main timer shaft 6; both shafts 6, 7;
rotates when the main shaft 6 is rotated by the winding force of a coil spring 8 wound around the sub dial 7a, and both ends of the coil spring 8 are connected to protrusions formed on the main dial 6a. When rotating the auxiliary vehicle 7 facing both sides of the vehicle 9, only this is rotated.

Timer cams 10 and 11 of the main width are connected to the lower ends of both shafts 6 and 7 on the right side of the gas valve 5 on the same axis line and above and below, respectively. Shikishi 12 was made to be placed in the bag. The main and sub-timer cams 10 and 11 are composed of circular cams having relatively small and relatively large diameters, respectively, and have recesses 10a and 11a at the outer edges, respectively. 10a,
11a coincides with the follower 12 and the gas valve 5 is in a state of interlocking valve.
, 11 and set the timer time,
Due to the rotation of the sub-timer shaft 7 in conjunction with the rotation of the main timer shaft 6, the concave portion 11a of the sub-timer cam 11 is moved into the follower 1 as shown in FIG. 6c.
2, the follower 12 is pressed to the right by the peripheral green of the sub-timer cam 11 to fully open the gas valve 5, and then the follower 12 is rotated into the recess 11a. As the child 12 falls, it comes into contact with the periphery of the main timer cam 10, and the recess 10 of the main timer cam 10 contacts the recess 11a.
It is assumed that the gas valve 5 is kept in a half-open state until a matches.

Note that the half-open state here means a state in which the valve opening is half or less than the fully open state, and the gas amount is sufficiently throttled. The gas valve 5 and the follower 12 are provided with respective pieces 5a and 12.
A is connected to the right connector 14 which is sprung by the spring 13 to the timer cams 10 and 11. Furthermore, the connecting piece 12a extending from the follower 12 is connected to the screw part 14a at the tip of the connector 14. At the same time, the lotus piece 5a carried to the gas valve 5 is connected to the intermediate flange 14b of the connector 14 in a pressurized state by a spring 15, and as the connector 14 rotates, the lotus piece 12a is moved forward and backward so that the gap between the two continuous pieces 5a, 12a can be adjusted to be wide or narrow. In addition, the connector 14 is
The operator 16 inserted into the timer main body 1 is engaged with the engagement groove 14c at the tail end, and the timer main body 1 is operated by the operator 16.
The rotation can be adjusted from the outside.

In the drawing, 17 is a holding plate for the lotus pieces 5a and 12a, 18 is a stopper formed on the sub dial 7a to regulate the rotation range of the sub timer shaft 7, and 19 is between the main and sub timer shafts 6 and 7. This is a sealing material provided to prevent gas leakage from the screw insertion portion of the operator 16 and from the screw insertion portion of the operator 16.

Next, to explain its operation, the main width dials 6a, 7
According to the setting of the timer time in step a, the gas valve 5 is first opened to the full open state as described above, then to the half open state, and then closed after the set time has elapsed. When the gap between the continuous pieces 5a and 12a is narrowed from the state shown by the solid line in FIG.
11a, and when the gas valve 5 is fully open, as shown by the dotted line in FIG. Even when the gas valve 5 is half-open, the coefficient decreases as shown by the dotted line in FIG. 6c. In the above embodiment, the prong 12a of the follower 12 is screwed into the connector 14, but the same operation can be obtained by screwing the prong 5a of the gas valve 5 into the connector 14.

As described above, according to the present invention, either the gas valve or the follower is screwed into the connector so that it can be moved forward or backward as the connector rotates, and the gas valve is operated by rotating the connector from the outside. This device adjusts the relationship of the gas valve by adjusting the gap between the valve and the follower.The gas valve can be operated at any desired relationship for a set time by external operation, and the device itself has a simple structure. It has the advantage that it can be obtained at low cost.
