Abstract

PURPOSE:To effect optimum heat cooking at all times in accordance with foodstuffs by detecting the weight of the foodstuffs, determining the heat generation quantity of a heat-generating member both from the weight of the foodstuffs and from the weight change rate of the same after detection and controlling the heat generation quantity on the basis of the determination. CONSTITUTION:The title broiler comprises a skewer-shaped holding tool 1 for holding foodstuffs 2 vertically, a weight detector 3 for detecting the weight of the foodstuffs 2 held, a juice pan 4, a bar-shaped heat-generating member 5 and a cylinder-shaped heat-ray reflecting plate 6. A converting circuit 8 that converts a signal released out of the weight detector 3 into a weight value outputs the weight value of the foodstuffs 2. The time when the weight of the foodstuffs does not substantially change is preset, and the heat-generating member is driven via a driving means 9 for the heat-generating member to cook the foodstuffs by heating. When the weight change within a preset time is not detected, it is judged that no generation of steam is recognized even if the foodstuffs are heated, and heat cooking is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic fish griller capable of automatically grilling fish.

Conventional technology Traditionally, when grilling fish etc., a gas table etc.21\-
/ Using a grill, the surface condition of the fish was observed to judge the doneness of the cooking.

Problems to be Solved by the Invention However, in order to observe the fish, it was very time-consuming and complicated, as it required removing the fish from the grill and turning the fish over. Also, the fish was scorched on the grill and the cooking utensils were very dirty.

The present invention solves the above-mentioned conventional problems and provides an automatic fish griller that holds food such as fish vertically and automatically cooks it from its surroundings according to the weight or rate of weight change of the food. With the goal.

Means for Solving the Problems In order to achieve the above object, the automatic fish fryer of the present invention has the following features:
A support for vertically supporting food, a weight detector for detecting the weight of the supported food, a vertical heating element arranged parallel to the food for heating the food, and a vertical heating element for heating the food. It consists of a cylindrical heat ray reflecting plate provided so as to surround the heating element, and is equipped with heating element driving means for inputting a signal from a weight detector and controlling the amount of heat generated by the heating element.

3...-7 Effects Since the present invention has the above-described configuration, food such as fish is supported vertically in a skewered state or suspended state, and the food is heated and cooked from its surroundings. Since the amount of heat generated by the heating element is controlled based on the weight change rate, it is possible to automatically perform appropriate cooking. Therefore, the complicated work of observing the surface condition of the fish is not necessary. In addition, since the heat is applied from the surrounding area, there is no need to turn food such as fish over, the food does not burn on the grill, and the cooker is less likely to get dirty.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
The figure is a partially cutaway perspective view of an automatic fish griller. In the figure, 1 is a skewer-shaped holder for vertically holding food 2 such as fish. 3 is a weight detector that detects the weight of the held food 2; Reference numeral 4 indicates a saucepan, 5 indicates a rod-shaped heating element, and 6 indicates a cylindrical heat ray reflecting plate. In the above configuration, the weight detector 3 does not detect the weight of liquid such as water generated from the food 2 dripping onto the dish. 7 indicates an exhaust hole for exhausting smoke, water vapor, etc. generated from the food 2. 8 is a conversion circuit that converts the signal from the weight detector 3 into a weight value, and outputs the weight value of the food 2. Reference numeral 9 denotes a heating element driving means, which controls the amount of heat generated by the heating element 5 based on the weight value. FIG. 2 shows the change over time in the weight detected by the weight detector 3 when the food 2 is cooked. Figure 2 (a) shows the time (1) change in food weight (wI), and Figure 2 (b) shows the time (1) change in food weight change rate (1 town time Δ). .A and B in Figure 2(b)
,C.

D indicates a region with a small weight change rate (Al, a medium region (B), a large region (C1), a region with a gradual decrease (DJ), and a region A indicates a region where the weight hardly changes, If food 2 is raw fish, this region is long,
For dried fish, etc., this area is short.

The region indicates the region where the temperature of the food 2 increases and steam is generated. Area C indicates an area where liquid such as water generated from food is dripping onto the saucepan 4. If the food is dry, such as stockfish, this region will be very short or non-existent. The area indicates the area where the temperature of the food becomes sufficiently high, there is no dripping moisture, the inside of the food is cooked, and the degree of dryness gradually increases, and indicates the finished state of the food 2 after cooking.

FIGS. 3(a) to 3(e) show flowcharts of the operation of the heating cooker configured as described above.

First, the food 2 is placed on the holder 3 and cooking begins. In step 11, the weight W of food 2 is determined.

is detected by the weight detector 3, and the weight W is transmitted from the conversion circuit 8 to the calorific value driving means 9. is output. Time t at this time.

is stored in the calorific value driving means 9.

In step 12, a time t4 corresponding to the weight value w0 of food 2
, a time is set during which the weight of the food hardly changes, and the heating element is driven in step 13 via the heating element driving means 9 to heat and cook the food. In the time judgment of step 14, if no weight change is detected within the preset time t1, it is determined that there is no load in step 15, that is, no steam is generated even if the heating is performed, and the cooking is finished. Unloaded 6 ・＼-7 Notifies the outside that it is a load. If water vapor or the like is generated from the food within a preset time t1,
When a change in weight or a decrease in weight is detected, the determination function in step 16 determines that a region mill has been detected. In step 17, time t1 of area A is determined. In step 18, the weight W of the food. The type of food is roughly determined based on the time t1 and time t1. For example, if the food is raw fish, wo is relatively large and tl is short. Also, if the food is dried fish, W. is relatively small and t is large. Time t2, the time at which the weight change rate changes, is set, and the process moves to step 19. Even if the weight change rate (7 pieces) is large within the preset time t of ΔW,
If it does not become smaller, step 2° occurs, it is determined that there is an abnormality, and the heating cooking is terminated. If the weight change rate (7-) becomes large within time ΔW, that is, the rate of weight decrease becomes faster, it is determined in step 21 that region C has been detected, and the process moves to step 22. If the decreasing speed becomes slow, it is determined in step 23 that an area has been detected, and the process moves to step 34.The area C is detected,
If step 22 is reached, the type of food is determined to be raw fish with a high moisture and fat content. Determine time t2 and, in step 24, determine the weight Mwo of the food.

A time t3+weight W depending on t, w, t, etc. is assumed and the process moves to step 25. If the weight reduction rate does not decrease within time t3, or if the weight becomes less than w3, it is determined that there is an abnormality and the process moves to step 26.
Finish cooking.

Region D, if the weight loss rate becomes slow, step 27
Accordingly, it is determined that the area has been detected, and the process moves to step 28. In step 28, time t3 and weight w are determined,
These values and the weight W. Step 2
Assuming a finishing time t4 and a finishing weight W, heating is continued in step 30 until time t4 or in step 31 until the weight of the food becomes less than w4, and in step 32, heating is continued. Determine that it is finished and proceed to step 33.
to finish cooking.

Next, in step 23, it is determined that area O has been detected following area B, and in step 34, at time t2. Once the weight w2 is determined, in step 35, the type of food,
For example, it is determined that it is a dried fish, the time t4', the weight VV 4
', and the process moves to steps 36 and 37. Step 36
Then, in step 37 it is determined whether the time t4' has been exceeded, and in step 37 it is determined whether the weight has become less than VV4, and in step 38 it is determined that the cooking is finished, and in step 39 the heating cooking is completed.

In addition, in region O, the calorific value of the heating element is defined as region A,
Compared to B and C, it was found that when the amount was slightly reduced, the finished product of the food became more beautiful.

According to the configuration of the above embodiment, the type of food can be automatically determined based on the weight of the food, or the time and weight of each area, and the heating element for hot cooking according to the type of food. heat generation], it is easy to operate, and it is possible to achieve beautiful finished cooking and optimal cooking.

In the embodiment of the present invention shown in FIG. 1, there is only one rod-shaped heating element, but if a number of rod-shaped heating elements are installed inside the cylindrical reflecting plate, the heating of the food becomes more uniform, and the present invention 9-7 It is clear that the same effect can be obtained. Further, the heating element may be an electric heater, a gas burner, or a radiant heat emitter. In addition, although FIG. 1 shows a skewer-shaped food holder, the present invention is not limited to this, but a hook-shaped device provided near the exhaust hole to hang the food is not limited to this. Even if the configuration lowers the
It is clear that effects similar to those of the present invention can be obtained.

Furthermore, if the food rotates horizontally around the holder, the heating of the food becomes even more uniform. Therefore, in this case, even with only one heating element, food can be heated and cooked uniformly. In this case, the weight value of the food includes an error due to rotation, but the weight value can be adjusted by synchronizing the rotation period.
The weight of the food can be detected with sufficient accuracy by detecting it or averaging it for each rotation, and the heating and cooking of the food can be controlled by changing the weight of the present invention.

In addition to the effects of the invention, as is clear from the description of the examples, the present invention 10/
＼7 is designed to detect the weight of food, determine the subsequent calorific value of the heating element from the food weight and weight change rate, and control the calorific value based on this determination. It is possible to perform optimal cooking according to the cooking conditions. Therefore, the optimal finished state according to the food product can be automatically obtained at all times.

Therefore, there is no need to observe the surface of food such as fish, or to take out and turn the food over, which saves time and effort. Furthermore, since the food is held in a skewer-like or hook-like holder and heated from the surrounding area, there is no risk of the food being scorched on the grill.
