Abstract

PURPOSE:To lessen dispersion in broiling a fish by mounting a temp. sensing device in a broiler, sensing the impression voltage on a heater and room temp., controlling the heater with the sensed temp. and voltage, and judging the workmanship of broiling the fish. CONSTITUTION:Upon setting the initial value, a heater 7 is fed with current at a current feed rate of 100% until the internal temp. (GT) of the grill case body 6 sensed by a temp. sensing device 8 attains a specified level GTO while the room temp. is being sensed by a room temp. sensor. After exceeding GTO, a current feed rate of 85% is observed, and preheating is made until GT attains another specified level GT1. At GT1, a microcomputer 18 informs it vocally from a speaker 24 via a voice synthesizing circuit 23 with the aid of a temp. sensing circuit 20. After loading a fish, the period of time t1 in which GT attains a third specified level GT2 from the GT1 is measured while the rate of current feed to the heater is held at 85% as it has been, and this is stored in the microcomputer 18. On the basis of the temps. sensed by the temp sensing device and room temp. sensor and the voltage sensed by a voltage sensing circuit, control of grill heater is conducted so that the fish is broiled automatically.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to an automatic fish grilling device. 6. Prior Art In the conventional fish grilling device, the user can turn the fish over and adjust the finishedness of the fish based on his/her experience. was judging.

Problems to be Solved by the Invention With conventional fish grilling devices, the user has to judge the doneness of grilling, resulting in considerable variations in the degree of grilling, such as sometimes burning the fish or half-cooking the fish. Ta. There was also the problem that the time required to grill the fish varied depending on the room temperature, and that the fish could not be cooked properly even with a timer or the like. Furthermore, there was the inconvenience of not being able to safely perform other tasks while grilling fish.

Means for Solving the Problems In order to eliminate the above-mentioned variations in the quality of grilled fish, the present invention attaches a temperature detection device to an appropriate position of the grilled fish cooker, and further adjusts the voltage applied to the heater, which is the heat source, and the room temperature. The heater is controlled based on these detected temperatures and voltages, the degree of grilling of the fish is determined, and each process is notified by notification sounds such as voice.

Function As mentioned above, a temperature detection device and a voltage detection circuit are installed at appropriate positions of the fish frying cooker, and a room temperature detection device and a control circuit that controls the heater, which is a heat source, based on these detection signals are provided. The system detects the temperature and room temperature inside the fish frying cooker to determine the degree of grilling of the fish, and also detects voltage fluctuations and changes the amount of power of the heater to maintain the optimum amount of power and cook the fish. This system notifies you of the time to turn the fish and the time of completion of the fish through audio or other notification sounds, so that the fish is always grilled and in good condition.

Example An embodiment of the present invention will be shown below.

FIG. 1 is a perspective view of an electric stove equipped with an automatic fish grilling cooker according to an embodiment of the present invention, in which a main body 2 of the stove is installed in a system kitchen 1, and 3 serves as an automatic fish grilling cooker. This is the grill part. Reference numeral 25 denotes a room temperature detection device (hereinafter referred to as a room temperature sensor) provided on the front surface of the main body 2, and is provided at a location that is not affected by the heat of the heater.

FIG. 2 is a side sectional view of the grill part 3 shown in FIG. is provided with an exhaust hole 5 for discharging smoke from grilled fish, a grill door 9 on the front, and a grill heater 7 (hereinafter referred to as heater) made of a sheathed heater at the top. Reference numeral 4 denotes a grill plate, which is integrally connected to the grill door 9 and is detachably attached to the grill case main body 6. Furthermore, 8 is a temperature detection device attached to the center of the side surface of the grill case body 6. Further, 10 is a grill grid placed on the grill plate 4.

It is controlled by a triac drive circuit No. 9. J4 is a power transformer, and its secondary output has two systems, one of which supplies a DC stabilized voltage to the entire control circuit in a 17 power supply circuit via a 16 diode bridge. Further, the other secondary side outputs of the power supply 1 to the lance 14 are connected to a voltage detection circuit 15 which is a means for detecting the power supply voltage.
Detects voltage fluctuations on the primary side. 20 is a temperature detection device 8
21 is a display circuit for the stove operation section, 22 is an input circuit for various keys, 23 is a voice synthesis circuit, and audio is output from 24 speakers. 26 is a room temperature detection circuit that converts the temperature obtained by the room temperature sensor 25 into an electrical signal. 18 is a microcomputer that controls all of these.

FIG. 4 is a sequence showing the relationship between the temperature detected inside the grill and the time for grilling fish.

In the embodiment of the present invention configured as described below, water is first poured into the grill plate 4, and the grill 10 on which the fish is placed is placed on the grill plate 1.
- Place it in the grill case main body 6 and start the automatic fish grilling sequence. As shown in FIG. 4, first, the room temperature is detected by the room temperature sensor 25, and an initial value is determined. The heater 7 is energized at a 100% energization rate until the temperature GTo is reached. After exceeding GTo, the energization rate is 85
% and preheats GT until it reaches a predetermined temperature GT1.

This preheating has the effect of uniformizing the temperature inside the grill and preventing the skin of the fish from sticking by heating the grill 10. As a result of this preheating, the GT changes to GT, and at the same time, the temperature detection circuit 20 causes the microcomputer 18 to issue a voice message from the speaker 24 through the voice synthesis circuit 23 saying, "Please put the fish in." Next, after the user puts the fish in, the energization rate of the heater remains at 85% until the GT reaches a predetermined temperature GT2, and the time t1 from GT to GT2 is measured and stored in the microcomputer 18.

Here, the length of time varies depending on the number, size, and type of fish, the amount of water put in the grill plate 4, and the room temperature.For example, the longer the number of fish, the shorter the size, but for many grilled fish As a result of the experiment, based on this variable time t, the time T required to turn the fish over is T1 = t1 + t2, and the time T required to turn the fish over after turning it over is = T1Xα□ (α1 is a preset constant). Almost exactly determined l-11
,tL is known.

In this way, it is important to accurately measure the time required for the temperature to rise from GT1 to GT2.
It is necessary to suppress the amount of heating until it reaches GT 7 to avoid variations in the humidity inside the chamber due to a sudden rise in temperature, and to avoid errors in the measurement of temperature. In the embodiment, the heater 7 is controlled at an energization rate of 85%. If this energization rate is further reduced to 11, the open side will be more accurate, but there is also the disadvantage that the overall fish grilling time will be longer.
An appropriate value should be determined based on the balance between the two, and although it was set to 85% in the example, it is not limited to this.

The time from adding the fish to turning the fish over is as described above <r1
At this point, the message "Please turn over the fish" is issued, and furthermore, after T2 hours, the message "The fish is cooked" is issued to the voice synthesis circuit 2 according to instructions from the microcomputer 18.
3 from the speaker 24.

Furthermore, in Figure 4, ``The time a required for the fish to be grilled after measuring a series of t□'' is related to the situation and taste. It is important to note that if the power supply voltage fluctuates during this time, it will greatly affect the quality of the fish.

That is, since the amount of heat generated by the heater 7 is proportional to the square of the voltage, if the voltage increases slightly, the food will be overcooked, and if the voltage decreases slightly, the product will be undercooked. In order to always grill fish accurately even when there are fluctuations in the power supply voltage, the present invention is equipped with a voltage detection circuit 15 that detects the voltage at certain fixed time intervals during the grilling time a, and detects the voltage at time t2. This is a correction. By correcting 2, the time until turning over T□
The time T2 until the product is completed will also be corrected.

For example, if the power supply voltage is high, shorten t2, and therefore a
shorten, and if the voltage is low, lengthen L2 and a,
This ensures uniform and accurate baking at all times.

Furthermore, the voltage detection circuit J5 detects and corrects fluctuations in the power supply voltage, and the temperature detection device 8 also detects fluctuations in the internal temperature due to fluctuations in the heating amount of the heater 7 due to voltage fluctuations. Through detection, it is also possible to more accurately understand and control fluctuations.

In this way, by correcting the times t2 and a to optimal values in response to voltage fluctuations, the amount of power of the heater 7 is always controlled to be optimal for grilling fish.

Effects of the Invention As explained above, the grill heater is controlled based on the detected temperature detected by the temperature detection device and the room temperature sensor, and the detected voltage detected by the voltage detection circuit, and the fish is automatically grilled. The timing of putting the fish on the grill is unaffected by the size, amount of water put in the grill plate, room temperature, and fluctuations in power supply voltage while grilling the fish.
By letting you know when it's time to turn the fish over and when it's time to grill it, anyone can enjoy the fish without any distinction.
The practical effects of the present invention are extremely large, as the user can burn the item by hand, and since the notification is given by voice, the person can do other work with peace of mind.
