Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a cooking device such as a gas range with improved control and operation of gas consumption.

Conventional configurations and their problems Conventional manual-operated models, for example, have a structure in which you first press a push button switch to ignite, and then adjust the calorie consumption to your desired gas consumption, making the operation complicated. and
Furthermore, it was necessary to keep pressing the push button until the thermo-element for ignition confirmation heated up. In addition, there was no means to indicate whether the main valve was open or closed, and the appearance was unclear, so there was a risk of forgetting to close it, and there was a great danger that the gas could be combusted by a child's mischief. .

In other words, in Fig. 4, when the main valve (not shown) is opened and the "Push" button (1) is pressed, the pilot ignites and ignites the main burner, and the ignition is caused by the heating of the thermoelement. Once detected, the main burner continues to burn even if the push button (1) is subsequently released. The main burner burns according to the damper opening degree of the gas supply path. Therefore, in the conventional heating cooker, it is necessary to perform an ignition operation and to operate a calorie setting damper adjustment means consisting of a slide knob (2) shown in FIG.

OBJECTS OF THE INVENTION In order to eliminate the above-mentioned conventional drawbacks, the present invention aims to provide a heating cooker that adjusts the calorie content by touching the burner, and constantly performs ignition and ignition confirmation at the maximum flow rate in the main burner. It is.

Structure of the Invention In the gas heating cooker of the present invention, a solenoid valve is inserted into each of a plurality of branch passages originating from a main valve flow passage, and the downstream ends of these branch passages are merged and guided to a burner. A gas circuit including a spark plug and a thermoelement, and one or more of the plurality of solenoid valves.
a plurality of pushbutton switches for selectively opening one of the solenoid valves and guiding a required flow rate of gas to the burner; a stop pushbutton switch; a timer operation for setting the opening time of the selective solenoid valve; an operating section including a display means;
When one of the pushbutton switches is selected and the timer is set, all of the solenoid valves are opened to ignite all calories, and after confirming the ignition with the thermoelement, the solenoid valves are closed. The solenoid valve is characterized by comprising microcomputer control means for starting the set time of the timer by keeping it selectively open, and closing all of the solenoid valves when the set time ends or the stop push button is operated. It is something.

As described above, according to the present invention, ignition can be reliably performed with a single touch, and preferably light means corresponding to the main valve and each push button can be provided to display the safety and other status of the main valve. In addition, when the burner flame is blown out, the thermoelement becomes low, so all solenoid valves close, and all display rungs go out to notify that the fire has been extinguished, making it extremely safe.

Embodiment FIG. 1 is a schematic sectional view showing the configuration of a gas flow path and a control circuit in an embodiment of the present invention.

The gas flow path starts from the main valve αQ, passes through the connecting pipe 0υ, the governor, and reaches the branch passages α罎 and α, in which it passes through the solenoid valve O5 and Oliice αη, and at the branch passage C141. is connected to the merging path H via the electromagnetic valve aQ and the oriice (to), and reaches the burner □□□ from the nozzle/L'H at its terminal end via the damper QD. The spark plug (
g) and a thermoelement for ignition confirmation (c) are arranged facing each other, and their lead wires (23a) and (24B) are connected to a microcomputer controller (c). A main valve switch (1) interlocked with the main valve OQ is further connected to this controller (to).

FIG. 2 shows a plurality of /<-sl
This figure shows the state in which it is assembled into a system kitchen equipment, where (6) shows a plurality of burners, and (7) shows the operation buttons and display sections for each door arranged horizontally. The burner operation spring /l/ (8) is an open operation spring μ in which open operation buttons are arranged, (9) is a pocket lid, and QO is the main stopcock in the pocket lid (9).

FIG. 8 is an enlarged view of the burner operating spring shown in FIG. 2, and shows blocks A, B, C, and D arranged horizontally, each consisting of a push button and related elements corresponding to each burner. , the center row of pushbuttons (3) includes a stop button labeled S'' and a stop button labeled 'I'', 'l'' and 1)'', respectively.
It includes a solenoid valve selection button pushbutton for low, medium and high combustion labeled , and the LED array (4) above it includes four LED light elements corresponding to each of said buttons. Further, a timer operation and display band (5) is provided below the pushbutton row (3).

The gas flow path and control circuit shown in FIG. 1 operate as follows in relation to the operation section shown in FIG. 3. The user first opens the main valve αQ, thereby turning on the main valve switch, and the microcomputer controller causes the rightmost LED (4g) corresponding to the stop button (36) on the operation panel to blink.

Next, when any solenoid valve selection button, for example, weak combustion button 1 (3a) is pressed, the microcomputer controller (
2), and at the same time the corresponding LED (4Jl) blinks and the stop button LED (4m) goes out.

It should be noted that this state simply means the registration of calorie selection (in this case, weak combustion), and that the system performs the solenoid valve opening operation only when the two states of calorie selection and timer operation are established. . Therefore, if the user touches the ``10 minutes'' position on the timer operation band (5), the time scale of this timer operation band (5) will change to ``J10''.
A red line lights up up to the point, and at the same time, the solenoid valve (to) and QQ in the branch path Q3, α→ from the main valve flow path are opened together. The pressure of the raw gas coming out from the main valve is regulated by the governor (2) in the flow path αη, and it passes through both the small calorie (weak combustion) branch passage αJ and the medium calorie (medium combustion) branch passage α→, so that all At the calorie flow rate, from the confluence path α, through the claw /l/(1) and the damper C21), the burner (2)
reach. At the same time, the ignition bladder generates a spark against the nearby flame port, which causes the burner to
When the thermo-element (c) detects that the microcomputer controller has ignited, the microcomputer controller) receives the detection signal and terminates the spark of the ignition plug, and closes the solenoid valve ←e of the intermediate calorie branch path. A "small calorie" state is established by keeping only the small calorie electric cable Atsu open.

The microcomputer controller also supports the weak button and ED (4K
) is switched from blinking to lit to indicate a 'small calorie' state. This small calorie burning continues for a time set by a timer, for example 10 minutes, after which the microcomputer controller (7) When the boat Ql is closed, the LED (4a) goes out, and the LED (4g) corresponding to the stop (S) button flashes again to indicate that the main valve is open again and is in the "standby state". Setting the timer. Even if you press the stop (S) button (3s) during the time, the small calorie burning will end and you will return to the standby state.

The above sequence is for the case where ``small calorie burn'' is selected, but if you press the middle button ``l'' (: (b) and select ``medium calorie''), the thermo element (c)
The only difference is that after ignition is confirmed by , the solenoid valve α closes, the medium calorie solenoid valve Q6 remains open, and the medium calorie indication LED (4b) changes from blinking to lighting. It is the same as the case of ``°small calorie''.In addition, when ``full calorie'' is selected, following the ignition operation that opens the entire calorie flow path, the solenoid valve αG
1αQ is maintained as it is in the open shape portion.

In addition, each operation block on the operation panel (7) for multiple burners shown in FIGS. 2 and 3 is one digit, and the 1 and Lm selection buttons in each digit are "°1", '2", !13 m
A code number is set for each machine as follows, and only when this code number, for example '2231' is pressed, will the state go from a simple main valve 6'° state to a true '° standby' state. It is also possible to enable selection operations and timer setting changes.In this case, the LED (4g) corresponding to the S button will blink when the former officer releases it.
It is advantageous for the user to be able to distinguish between the various states by entering the recited number into the 6" lighting state, which indicates a true standby state.

In the above explanation, it is assumed that the I and ED arrays (4) corresponding to the stop button and each calorie selection button are provided in parallel to these buttons. formed from a transparent or translucent material;
An LED or neon lamp may be attached inside the button, so that the button itself may emit light.

Effects of the Invention Ultimately, according to the present invention, the following effects can be obtained.

(1) It is easy to operate because the flame power can be adjusted and ignited with one touch.

(2) Since the ignition operation is stored in the microcomputer, there is no need to keep pressing the selection button until the thermoelement detects ignition, just by lightly touching it.

(3) To erase it arbitrarily, simply touch the S button with your finger.

(4) If the main valve is open, press the stop button
Since the corresponding light of I is blinking or lit, this draws the user's attention and allows the user to proceed to the necessary operation without leaving room for dangerous operations such as those caused by mischief by children or the like. Furthermore, since the uS'' light goes out when the main valve is closed, the user can confirm that the main valve is "closed" and leave the area.

(5) Security can be further increased by using a code number system.

(6) Each solenoid valve can be set to a microcomputer timer, so it can be automatically stopped at a specified time.
