Abstract

PURPOSE:To prevent an accident due to main valve left open from happening by a method wherein the displaying mode of a digital electric time piece is differentiated by opening and closing operation of a main valve so that any users may easily notice the opened or closed status of the main valve. CONSTITUTION:A gas oven main body 1 equipped with a digital electric time piece with timing knob 3, timer adjusting knob 4 and displaying elements 5 is connected to a display control circuit 13 with a transfer switch 12. Next the display control circuit 13 is connected to an ignition control circuit 14 provided with a driving coil 11 interlocking with a gas electromagnetic valve 8 while a transfer switch 12 and an operating element 15 of main valve 7 are also interlocked so that the transfer switch 12 may be connected to the time displaying side in case the operating element 15 is closed and to the cooking timer displaying side in case the operating element 15 is opened on the contrary. Through these procedures, any users may easily notice the opened or closed status of the main valve 7 at a glance.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas opener equipped with a digital electric timepiece that displays the time using a display element (numerals, colons, etc. formed of liquid crystal, light emitting diode, etc.).

Needless to say, the safety of gas opening must be sufficiently ensured. However, in general, in gas open systems, there are few cases in which the user closes the original pulp after open use, and in many cases, the original pulp remains open.
However, they are in a dangerous situation where there is no guarantee that raw gas will leak out from the gas outlet at any time.

The reason for this is that in conventional open valves, the operating body for opening and closing the main valve is located in a location that is difficult to see, for example, inside the open container, making it difficult for the user to notice if he or she forgets to close the main pulp.

The present invention has been made with attention to the above-mentioned problems, and an object of the present invention is to provide safer gas opening by indicating the open state of the original pulp using a display element of a digital electric clock. In order to achieve the above object, the present invention provides a source pulp disposed in a gas passage leading to a gas bath that heats the inside of an open warehouse, an operating body that opens and closes this source valve, and a display element that displays the time. and a digital electric light clock, which allows the operation of the original pulp to be performed using the operating body.
The display form of the display element when "open" is changed to the original pulp "closed"
This is a gas-open configuration that is different from the display format used at the time.

Based on this configuration, the user can determine whether the gas source valve is open or closed just by looking at the digital electric clock, and can prevent the user from forgetting to close the gas source valve. Since this is performed in conjunction with the opening and closing of the original pulp, a reliable switching display can be obtained.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overall configuration diagram of the gas open system. In the figure, reference numeral 1 denotes an open main body, and the operating section of the open main body 1 includes a digital electric light clock 2, a time adjustment knob 3. A timer adjustment knob 4 is provided which is used to indicate the cooking time.

Inside the open main body 1, a gas supply path is formed which draws gas from the outside through a gas passage 6, passes through the original pulp 7, a gas electromagnetic valve 8, and reaches a gas burner 9. Note that when current flows through the first drive coil 11 of the gas solenoid valve 8,
The excitation force opens the valve to allow gas to flow in. 13 is a display control circuit, and a changeover switch 12
In response to opening/closing, the time display and the cooking timer one hour display are selected respectively, and the display element 6 of the digital electric clock 2 is turned on. Further, this display control circuit 13 has a built-in timer circuit. 14 is an ignition control circuit, which controls the drive coil 1 according to the output signal from the display control circuit 13.
Controls the operation of 1.

The operations of the changeover switch 12 and the original pulp 7 operate as a series of operations. In other words, the operating body 16 of the original valve 7 is
When "closed", the selector switch 12 is connected to the time display side, and the digital electric clock 2 functions as a time clock. On the other hand, when the operating body 15 is "open", the selector switch 12 is connected to the logical timer one-hour display side, and the digital electric clock 2 has a function as a cooking timer. At this time, if you operate the timer adjustment knob 4 to set the cooking time, that time will be displayed on the digital electric clock 2, and when the cooking time changes, the drive coil 11 will operate and the gas solenoid valve 8 will close to start cooking. finish. The gas solenoid valve 8 is opened in conjunction with the ignition operation.

FIG. 2 shows an example of an interlocking mechanism between the changeover switch 12 and the knob 7 described above.

The main valve 7 is connected to the gas passage 6 and has a mechanism in which gas flows through the gas distribution hole 16 by rotating the operating body 15 . FIG. 3 shows a view seen from the operating body 15 side in FIG. 2. As shown in the figure, when the operating body 15 is rotated from the V position to the H position, the gas flow hole 16 becomes perpendicular to the gas pipe port 18, and the gas flow is stopped. Further, along with the above operation, the contact lever 17 is simultaneously rotated from the position V' to the position H'. When the contact lever 17 is in the V' position, the operating body 16 is in the V position, and the gas flow hole 16 is in a state where gas flows. At this time, the contacts 19 and 20 fixed by the holding base 21 come into contact with each other by the contact lever 17. That is, contact point 19.
20 constitutes a component of the changeover switch 6. The contact 19°2o has a spring characteristic that opens when the contact lever 17 is in the H' position.

FIG. 4 shows an embodiment of the display on the digital electric timepiece 2. FIG. When the original pulp 7 is closed, the time is displayed as shown in a of the figure. When it comes time to start cooking and the original pulp 7 is opened, the display function is switched to a cooking timer as shown in FIGS. The current state indicates the state before the cooking timer is activated, and C indicates the state during cooking. In this case, diagram C represents the cooking time of 23 minutes, but if the cooking time is decreased as the cooking time progresses, the remaining cooking time can be gradually notified to the user, and eventually the cooking time will be stopped in the form shown in b. Just do it.

In this embodiment, the presence or absence of the symbol "AMJ" or "PMJ" indicates the difference in the display between the time and the cooking timer for one hour.

According to the present invention, as the original pulp opens and closes,
Since the display form of the digital electric light clock can be automatically changed, and the user can easily determine the open/closed state of the gas source valve just by looking at the digital electric light clock,
This makes it possible to prevent the risk of disasters caused by forgetting to close the original pulp.
