Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a time display device in a cooking appliance equipped with a timer.

(Prior Art) Conventionally, an ignition operator that operates an igniter opens a gas valve inserted in a gas supply path connected to a gas burner, and at the same time senses the temperature of a cooking pot heated by the gas burner. In a type of cooker that closes a solenoid valve inserted in the gas supply path when a temperature sensor detects a predetermined temperature of the cooking pot, the temperature sensor detects a predetermined temperature of the cooking pot, for example, when the rice is cooked. When the temperature is detected, the gas supply path of the gas burner is automatically cut off and combustion is stopped without the ignition operator returning to the operation starting position.

However, with this cooker, it is not possible to determine when combustion has stopped, nor is it possible to determine when it is okay to return the ignition control to the starting position.Furthermore, when cooking according to the time, the elapsed time is not known, so You need to be mindful of your time.

Furthermore, if a timer is provided separately to determine the elapsed time, there is an inconvenience that the timer must be operated separately.

Therefore, it is desirable to operate the timer simultaneously with the ignition operation by the ignition operator, and to be able to know the time in accordance with the automatic return of the timer operator.

(Problems to be Solved by the Invention) An object of the present invention is to provide a time display device for a cooking appliance that meets such demands.

(Means for Solving the Problems) The present invention operates an ignition operator that operates an igniter to open a gas valve interposed in a gas supply path connected to a gas burner, and the gas is heated by the gas burner. A cooking device of a type that closes a solenoid valve interposed in the gas supply path when a temperature sensor detecting the temperature of the cooking pot detects a predetermined temperature of the cooking pot, wherein the cooking device is provided with a timer; the operating element is switched to the operating position together with the switching operation of the ignition operating element to the ignition position,
The operation element of the timer is configured to be able to return automatically by itself, and a scale is provided along the locus of movement of the operation element of the timer.

(Example) The present invention will be explained below with reference to the drawings.

Figures 1 to 4 show an example of the implementation of the present invention. 7 is a solenoid valve inserted into the gas supply path 4; 8 is a spring that is switched to the operating position by a lever-type operator 9 that automatically returns. 10 is a scale along the movement trajectory of the operator 9; 11 is a cooking section 13 having a cooking chamber 12 on one side; a grill cooking section 14 on the other side; Stove part 15
16 is a gas cooker consisting of a gas valve 3 and an electromagnetic valve 7. In the illustrated one, a cooking pot 6 is arranged in a cooking chamber 12, and a gas burner 2 is installed below the pot 6. and a temperature sensor 5, and a gas supply path 4 to the gas burner 2 in the cooking section 13.
is arranged, and a gaskottoku 16 is interposed in a part of it,
A timer 8 is installed adjacent to this Kotoku 16,
A knob part 1a of an ignition operator 1 and a knob part 9a of a timer operator 9 are slidably arranged on a front panel 17 of a main body 11 of the cooking device. The cooking pot 6 can be moved in and out through the opening 11a of the main body 11.

As shown in FIG. 3, the ignition operator 1 is connected to the gas tank 16 via an operating lever 18, and the timer operator 9 is connected to the timer lever 1.
As shown in FIG. 4, each lever 18, 19 is movably inserted into each groove 20, 21 provided in the front panel 17 of the main body 11. Each groove 20, 21 is held at one end side, that is, at the starting position shown by the solid line in FIG. 4, and the ignition operator 1 and the operator 9 are provided so as to be simultaneously switched to the operating position.

In the illustration, a part of the knob 9a of the operator 9 is cut out, and the knob 1a of the ignition operator 1 is exposed to this notch.

5 to 7 show an example of the gas tank 16 used in the present invention. In the illustrated example, a gas valve 3 having a gas guide hole 23 is rotatably provided in the main body 22 of the gas tank 16. gas valve 3
is opened and closed in conjunction with the operating lever 18 on the upper surface, and a solenoid valve 7 is provided on the downstream side thereof so that the solenoid valve 7 is pushed by this and opened when the operating lever 18 is in the fully open position. When the operating lever 18 is tilted from the stop position shown by the solid line in FIG. 5 to the fully open position shown by the chain line in FIG. 5, the gas valve 3 is rotated to the fully open position via the drive plate 24. At the same time, the solenoid valve 7 is pushed open by the second driving plate 25, and when the operating lever 18 is then released from the fully open position, the bushing rod 26 is moved slightly backward by the return spring 26a to open the operating lever 18. is pushed by this and tilted slightly to the return side, but at this time, the drive plate 24 does not rattle and the gas valve 3 is maintained at the previous fully open position. In the figure, 16a and 16b indicate the gas inlet and outlet of the gas tank 16.

Next, the operation of the present invention will be explained.

For example, put a predetermined amount of rice and water into the cooking pot 6,
Place this on the gas burner 2, and then simultaneously push down the ignition operator 1 and the operator 9 of the timer 8 from the solid line in FIG. similarly moves downward,
When the position shown by the chain line is reached, the ignition operator 1 is switched to the ignition position, the gas valve 3 and the solenoid valve 7 are opened, gas is supplied to the gas burner 2, and the igniter is actuated by an appropriate means. As shown in Figure 8, the thermocouple 2 facing the flame hole of the gas burner 2 starts to burn slowly.
The electromotive force of 7 is applied to the solenoid coil 28 to keep the solenoid valve 7 open, and the gas valve 3 is also kept at the fully open position so that gas is continuously supplied to the gas burner 2 and combustion continues. When the timer 8 is switched to the operating position, the operator 9 starts automatic return. Next, as time passes, the operator 9 automatically returns to the starting position (indicated by the solid line in FIG. 4), and the indicator mark 9b attached to the operator 9 indicates the time on the scale 10.

Next, when the cooking pot 6 reaches a predetermined temperature like when the rice is cooked, the temperature sensor 5 in contact with the pot 6 detects this temperature, and as shown in the eighth figure, the temperature is changed between the thermocouple 27 and the solenoid coil 28. circuit 29
The thermocouple 27 is opened by opening the switch 30 intervened in the
The solenoid coil 28 is demagnetized and the solenoid valve 7 is closed to stop the gas supply to the gas burner 2.

After the preset time has elapsed, the operator 9 of the timer 8 stops returning, and when it returns to its starting position (shown by the solid line in Figure 4), a time end bell (not shown) will sound to indicate that cooking is complete. .

Furthermore, even when cooking is complete, the ignition operator 1 remains in the ignition position (as shown by the chain line in Figure 4), so when it is manually returned to the starting position, the gas valve 3 rotates to the fully closed position. is maintained.

Therefore, while the operator 9 is returning, it is of course possible to know the time at a glance by the scale 10.
When changing the cooking process as time progresses, it is possible to know the time, and after switching the operator 9 to the operating position, it can be returned to an arbitrary time for use.

Alternatively, only the gas burner 2 may be ignited by switching only the ignition operator 1 to the ignition position. Although the moving direction of each of the operators 1 and 9 is shown in the drawing as a vertical direction, the present invention is not limited to this.

(Effects of the invention) As described above, according to the invention, the ignition operator that activates the igniter operates the gas valve interposed in the gas supply path connected to the gas burner, and
When a temperature sensor that detects the temperature of a cooking pot heated by the gas burner detects a predetermined temperature thereof, a solenoid valve interposed in the gas supply path is closed. A timer is provided, and the timer's operator is configured to be switched to the operating position when the ignition operator is switched to the ignition position, and the timer's operator automatically returns independently. Since the scale is placed along the movement trajectory of the timer operator, it is possible to simultaneously ignite the gas burner and operate the timer in one action, and the automatic return of the timer operator makes it easy to see the time at a glance. This has the advantage of being able to maintain the gas valve in the fully closed position by returning the ignition operator.
