DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roaster such as an oven and a grill.

[0002]

2. Description of the Related Art Conventionally, in a roasting device such as a grill, a water dish is arranged at the bottom of a refrigerator to receive oil which causes smoke, in order to perform grilled food such as fish grilling which generates a flame at a high temperature. It has become. On the other hand, a roaster such as an oven generally did not have a water dish.

[0003] However, there has been proposed a roaster which has both functions of an oven and a grill and is capable of performing high-temperature grilled dishes and low-temperature grilled dishes.

[0004]

As described above, the grill is provided with a water tray as described above to prevent the generation of smoke. However, if the water in the water tray runs out, smoke is generated and the water runs out. Sometimes, the heating operation of the heating means is automatically stopped, but when the oven and the grill are integrated as described above, the heating operation of the heating means is stopped when the water in the water tray runs out as described above. In the case of adopting the method of making a dish, there is a problem that in the case of low-temperature grilled dishes such as cake dishes that do not require a water dish, there is a problem that the automatic heating stop function described above cannot be provided, and as a result, fish However, when performing high-temperature cooking such as that described above, there is a problem that smoke is generated by running out of water.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to prevent the generation of smoke by using a water dish for grilled dishes cooked at a certain temperature or higher. It is an object of the present invention to provide a roasting device that can stop heating when the water in the dish is exhausted, and can also cook pottery dishes at a temperature lower than the above-mentioned predetermined temperature, which does not require water to be poured into the water dish.

[0006]

In order to achieve the above object, the present invention provides a selection means for selecting a porcelain dish cooked at a certain temperature or higher and a porcelain dish cooked at a temperature lower than the predetermined temperature. A water dish placed at the bottom of the roaster cabinet,
Water detection means for detecting the presence or absence of water in the water dish, and only when a porcelain dish cooked at a certain temperature or higher is selected by the selection means, if there is a water-less detection signal from the water detection means, the heating means Heating control means for stopping the heating operation.

[0007]

According to the structure of the present invention, when a porcelain dish which is cooked at a high temperature above a certain temperature, such as a grilled fish, is selected by the selection means, if there is no more water in the water dish, the water detection means of the water detection means is used. The heating operation of the heating means can be automatically stopped by the function of the heating control means which has received the heat, so that it is possible to prevent the water in the water tray from running out and generating smoke.

On the other hand, when a pottery dish, such as a cake dish, which is cooked at a temperature lower than a certain temperature is selected by the selection means, the heating control means stops the heating operation of the heating means even if there is no water in the water dish. Because there is no food, you can continue cooking without any trouble.

[0009]

The present invention will be described below with reference to examples. FIG. 1 shows a schematic configuration of the interior of a roaster according to an embodiment of the present invention. Gas burners 1 are provided as heating means on both sides of the information in the interior. To cook the food 2 below.

When the object 2 is a cake or meat, the object 2 is placed in a storage using an iron plate or the like. When the object 2 is a fish or the like, a grill 3 is used as shown in FIG. Place in the refrigerator. A water plate 4 is disposed at the bottom of the refrigerator below the object 2 as shown in the figure, and water 5 is poured into the water plate 4 when cooking high-temperature ware such as grilled fish. The generation of smoke due to the oil dripping from 2 can be prevented.

At the bottom of the water tray 4, a temperature detector 6 that performs a switching operation when a constant temperature is reached using a thermoswitch or the like.
When the temperature of the water tray 4 evaporates and the temperature of the poured water 5 evaporates and rises to a constant temperature, the temperature detector 6 performs a switching operation to detect that there is no water. I can do it. That is, the temperature detector 6 constitutes a water detecting means. The switching signal of the temperature detector 6 is taken into the control circuit 7 as a waterless detection signal.

The control circuit 7 operates at a high temperature (for example, 300 ° C. or higher) at which the water 5 needs to be poured into the water dish 4 like a fish grill.
Grilled dishes cooked at 300 ° C, like cakes and meat
A signal from a selection switch 8 for selecting a low-temperature porcelain dish that does not need to be poured into the water dish 4 to cook in the following manner is taken in together with a detection signal from the temperature detector 6. When the selection by the selection switch 8 is a high-temperature grilled dish, when the temperature detector 6 generates a waterless detection signal, the solenoid valve 9 is controlled to a closed state to forcibly supply gas to the gas burner 1. It is designed to shut off and extinguish the fire. When the selection by the selection switch 8 is a low-temperature porcelain dish, the solenoid valve 9 is maintained in the open state even when the temperature detector 6 is generating the waterless detection signal, and the gas burner 1 is supplied to the gas burner 1. It can supply gas.

When using the roasting apparatus of the present invention, the selection switch 8 first selects a dish. Here, when a pottery dish requiring the water 5 to be poured into the water dish 4 is selected, the water 5 is poured into the water dish 4 in the refrigerator, and the food 2 such as fish is placed on the grill 3. Place. When the preparation for cooking is completed in this way, when the operation knob of the gas supply amount adjusting device 10 such as a proportional control valve or the like interlocked with an ignition device (not shown) is operated, the power supply of the control circuit 7 is turned on. Then, the control circuit 7 takes in the selection signal of the selection switch 8 and determines a pottery dish. At this time, since the high-temperature grilled dish has been selected, the control circuit 7 determines the presence or absence of the waterless detection signal of the temperature detector 6. The temperature detector 6 does not perform a switching operation because the temperature of the water tray 4 is close to the water temperature, that is, is in a state in which no water detection signal is output. Is output to open the solenoid valve 9.

For this reason, gas is supplied to the gas burner 1 through the solenoid valve 9 and the gas supply amount adjusting device 10. Here, the gas adjusted to the supply amount corresponding to the heating temperature by the gas supply amount adjustment device 10 is sent to the gas burner 1 and ignited by an ignition device (not shown). The gas is burned by this ignition, and the temperature inside the refrigerator rises due to the heat of combustion, thereby heating the food 2. Then, the water 5 in the water tray 4 boils and evaporates as the temperature in the refrigerator increases. When the water 5 in the water tray 4 runs out during cooking, the temperature of the water tray 4 rises rapidly and reaches the switching operation temperature of the temperature detector 6. In this case, the temperature detector 6 performs a switching operation and outputs a waterless detection signal to the control circuit 7. The control circuit 7 outputs a closing signal to the solenoid valve 9 in response to the water-out detection signal, and closes the solenoid valve 9.

Accordingly, the supply of gas to the gas burner 1 is stopped and the fire is extinguished, and the generation of smoke due to the drainage of the water tray 4 can be prevented. By the way, when the selection switch 8 is set to the low-temperature porcelain dish side where it is not necessary to pour the water 5 into the water dish 4 corresponding to cake dishes, meat dishes, etc., the control circuit 7 sends the temperature detector 6 The solenoid valve 9 is kept open without performing the operation of determining the presence or absence of the water absence detection signal. Therefore, oven dishes such as cake dishes and meat dishes can be performed without any trouble.

Incidentally, a fire extinguishing switch S interlocked with an operation knob or the like.
If the operation of W is performed, the control circuit 7 outputs a closing signal to the electromagnetic valve 9 to close the electromagnetic valve 9 and extinguish the gas burner 1.

According to the present invention, there is provided a selection means for selecting a porcelain dish cooked at a certain temperature or higher and a porcelain dish cooked at a temperature lower than the above-mentioned certain temperature, and water disposed at a bottom portion in a roasting cabinet. Dish, water detection means for detecting the presence or absence of water in the water dish, and only when a porcelain dish cooked at a certain temperature or more is selected by the selection means, if there is a waterless detection signal of the water detection means. A heating control means for stopping the heating operation of the heating means is provided, so that when selecting a porcelain dish which is cooked at a high temperature equal to or higher than a certain temperature, such as a grilled fish, the water detecting means is used if the water tray runs out of water. The heating operation of the heating means can be automatically stopped by the action of the heating control means which has received the water-less detection signal, thereby preventing the water in the water tray from running out and generating smoke. Lower than a certain temperature for cake cooking When the pottery dish which cooks at the temperature is selected by the selection means, even if there is no water in the water dish, the heating control means does not stop the heating operation of the heating means, so that the cooking can be performed without any trouble.
