Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grill for heating food such as fish and meat on a grill. In particular, it relates to a grill having an automatic fire extinguishing function with improved safety.

[0002]

2. Description of the Related Art When cooking a fish on a grill, if the fire is forgotten and the fire is left unattended, the fish may be burned out. In order to prevent such forgetting to extinguish, the grill is provided with an automatic fire extinguishing function.

[0003] In order to realize an automatic fire extinguishing function, the grill is provided with a timer which starts counting upon ignition. The timer issues a signal to extinguish the heating device after counting a preset time. The set time is longer than the time required for normal grilling and shorter than the time required to reach the temperature at which the fish starts to burn. For example, it takes about 15 minutes for double-sided grilling (heating is performed from above and below in the grill storage) and about 30 minutes for single-side grilling (heating is performed from the upper surface in the grill storage). With this feature,
If you forget to extinguish it, the fire will be extinguished automatically to prevent the temperature inside the grill cabinet from rising excessively. In a normal use situation, the heating device is manually extinguished before the timer automatically extinguishes.

FIG. 3 is a flowchart illustrating an example of a conventional automatic fire extinguishing function of a grill of a gas table stove. When the ignition button is pressed and ignited, the safety valve (SV) is opened in S21 to ignite. At the same time, the timer starts counting in S22.

Next, in S23, it is determined whether or not the timer has finished counting a predetermined set time. When the timer finishes counting, the process proceeds to S24, in which the safety valve is closed, and automatic fire extinguishing is performed. Note that this state is a case where the ignition button has not been manually extinguished and a predetermined time has elapsed and the user has forgotten to extinguish the ignition. At S23, while the timer is counting,
The case where the ignition button is turned off in S25 is the case where the heating and cooking are finished and the fire is manually extinguished. Also in this case, the safety valve is closed in S24. When the fire is extinguished, S2
At 6 the timer is reset.

[0006]

However, when cooking is performed continuously after the fire is extinguished, the temperature in the grill storage and in the grill pan is usually higher than the temperature at the start of use. Also, hot fat generated during the previous cooking may remain on the grill dish.

[0007] Even when the next cooking is performed in such a state, the time set in the timer is constant. Therefore, even if the user has forgotten to extinguish the fire in such a case, the fire extinguishing signal is not issued until the set time has elapsed.
Therefore, if heating cooking is performed in the grill cabinet which is initially in a high temperature state and the cooking is forgotten, the temperature in the grill cabinet may be too high when a predetermined set time has elapsed.

The present invention has been made in view of the above problems, and has as its object to provide a grill having an automatic fire extinguishing function that is safer even during continuous cooking.

[0009]

In order to solve the above-mentioned problems, a grill according to the present invention is a grill including a grill storage and a heating means such as a burner disposed in the grill storage.
A temperature sensor for detecting a temperature in the grill chamber, a timer for counting an elapsed time from the ignition of the heating means, and issuing a fire extinguishing signal when a certain time has elapsed from the ignition; and inputting a signal from the temperature sensor. And a control unit for controlling the heating means, wherein a set time of the timer is changed in accordance with a grill chamber temperature detected by the temperature sensor. By determining a predetermined time until the timer issues a fire extinguishing signal in accordance with the temperature inside the grill storage, the fire is automatically extinguished according to the situation inside the grill storage. For this reason, in the case of continuous cooking, even if the grill storage is at a high temperature, the fire can be automatically extinguished within a sufficiently safe time.

In the present invention, when the grill chamber temperature detected by the temperature sensor is higher than a predetermined temperature, the set time of the timer is set longer than a predetermined time until the timer counts and issues a fire extinguishing signal. Can be changed to be shorter. By setting the set time according to the grill temperature, the set time can be set to an appropriate time longer than the time for grilling the fish when the inside of the grill is hot and shorter than the time until the temperature at which the fish starts to burn. Can be set.

In the present invention, it is preferable that the temperature sensor is a thermocouple used for a burner extinguishing sensor. By using the thermocouple of the burner extinguishing sensor used conventionally as a temperature sensor,
The cost of the grill can be kept low.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view schematically showing a configuration of a gas table stove provided with a grill according to an embodiment of the present invention. In the gas table stove 1 of this example, a stove 3 is provided on an upper surface of a main body, and a single-sided (upper surface) grill 5 is provided inside the main body. On the front surface of the main body, there are provided a button for igniting and extinguishing the stove 3 and the grill 5, a knob for adjusting the degree of fire, and an opening for taking in and out the heated object to be cooked on the grill. The opening is closed by a grill door 7 that can be opened and closed. The gas stove 1 also includes a control unit 13 for controlling a safety valve 9 described later and for inputting a signal from the thermocouple 11. The control unit 13 also receives the operation status of the ignition button and the like, and further includes a timer 14.

The stove 3 is composed of a burner 15 provided on the upper surface of the main body and a virtue 17 provided around the burner 15. The grill 5 includes a grill burner 19 fixed inside the main body, a heat shield plate 21 and a glowing plate 23,
Grill plate 25 and grill 2 placed on grill plate 25
Seven. The grill plate 25 and the grill 27 are put in and out of the front through an opening in the front of the main body. Grill burner 19
A space of a predetermined height is formed between the grill and the grill 27, which serves as a grill storage. The object to be heated 29 placed on the grill 27 is cooked by the upper grill burner 19. Fat generated by heating the object to be heated 29 is
To fall. A grill exhaust port 31 is provided on the upper surface of the main body. The grill burner 19 is connected to a gas source via the safety valve 9. The safety valve 9 is controlled by the control unit 13.

A thermocouple 11 is mounted in the grill storage slightly below the grill burner 19. The thermocouple 11 detects the disappearance of the grill burner 19 and detects the temperature inside the grill storage. The output of the thermocouple 11 is sent to the control unit 13. If the temperature in the grill storage does not rise even though the ignition button of the grill burner 19 has been pressed, it is determined that it has gone out.

FIG. 2 is a flowchart illustrating the automatic fire extinguishing function of the grill of the gas table stove of FIG. The automatic fire extinguishing function automatically shuts off the safety valve (reference numeral 9 in FIG. 1) when the fire is not extinguished after a predetermined time has elapsed after the ignition button was operated and heating was started. Function to perform

When the ignition button is pressed to ignite, S1
Resets the timer of the control unit, opens the safety valve (SV) in S2, and ignites. At the same time, the timer starts counting in S3.

Then, in S4, the temperature in the grill storage is read from the signal output from the thermocouple. If the temperature (K) in the grill storage is equal to or lower than the predetermined temperature (K ₀ , for example, 150 ° C.), the count time (X) of the timer is set to the predetermined time (A, for example, 30 minutes) in S5. This time is a time sufficient for the object to be heated to be cooked when the inside of the grill storage is at a normal temperature (for example, about room temperature), and is a time shorter than the time when the object to be heated starts to burn. If the temperature in the grill chamber is equal to or higher than the predetermined temperature in S4, the count time (X) of the timer is changed in S6 to the actual temperature in the grill chamber (K) detected by the thermocouple and the normal count predetermined time. The time (B) is determined from the time (A) (details will be described later).
This time is a time sufficient for the object to be heated to be cooked when the temperature of the inside of the grill is high, and shorter than the time when the object to be heated starts to burn.

Next, in S7, it is determined whether the timer has finished counting the set time (X) according to the temperature in the grill storage. When the timer finishes counting, the process proceeds to S8, where the safety valve is closed, and the automatic fire extinguishing is performed. Note that this state is a case where the ignition button has not been manually extinguished and a predetermined time has elapsed and the user has forgotten to extinguish the ignition. If the ignition button is turned off in S9 while the timer is counting in S7, it means that the heating and cooking are finished and the fire is manually extinguished.
Also in this case, the safety valve is closed in S8.

The counting time (B) of the timer until the fire is automatically extinguished is determined from the actual grill temperature (K) detected by the thermocouple and the time (A) set in the normal case. Is done. For example, the newly set count time (B) can be obtained by subtracting the time (C) determined corresponding to the temperature (K) in the grill storage from the normal count time (A) ( B = AC, C =
f (K), C <A).
