Abstract

PURPOSE:To provide a normally stable baking color, by a method wherein, when a material to be cooked is baked, a time of energization of a load is automatically decided according to setting of the number of materials to be cooked and baking color. CONSTITUTION:When, for example, a number setting switch 11 is pressed only one time, a display means 14 displays 'TOAST' and '1', and when the number setting switch 11 is further pressed one more time, the display means 14 similarly displays 'TOAST' and '2'. When either of a plurality of baking color set switches is pressed, a microcomputer 13 decides a time of energization of a heater 16, being a load, according to the number indicated by the number setting switch 11 and a baking color set by baking color setting switches 12a and 12b,..., 12c. By outputting an output signal only for the set energization time, energization of the heater 16 is effected through transistor 15b, a relay coil 15c, and a relay contact 15d, all serving as a load energizing means, to bake a bread.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an automatic roasting apparatus (for example, an oven toaster).

2. Description of the Related Art A toaster oven is a conventional automatic roasting apparatus of this type, and has a construction as shown in FIG. 4Q. In FIG. 4, 1 is a timer setting means, and the energization time is set by the user turning the timer knob 1a. Further, a number display section 1b for displaying the number of pieces of bread, etc. to be roasted is provided near the knob 1a, and around the knob 1a, the number of pieces of bread, etc. A scale 1c indicating the energization time is provided. Reference numeral 2 denotes a load energizing means, which energizes the load 8 for that time when the timer setting means 1 sets the energizing time according to the number of pieces baked Iζ. The load 3 roasts bread or the like during the time when it is energized.

Problems to be Solved by the Invention With the conventional configuration as described above, when roasting bread, etc., it is necessary to set the timer accuracy by turning the timer accuracy while looking at the scale corresponding to the browning color of each piece of bread to be roasted. It is easy to accidentally read the coloring scale that corresponds to a different number of pieces, resulting in different roasting times, or due to the accuracy of the timer, the color of the food being roasted may vary. There was a problem that a stable browning color could not be obtained.

The present invention solves the above-mentioned conventional problems, and aims to provide an automatic roasting device that can always obtain stable browning without misreading the scale.

Means for Solving the Problems and Solving the Problems:Me+ζThe automatic roasting apparatus of the present invention includes one number designating switch for designating the number of items to be cooked, and operating the number designation switch. display means for sequentially changing and displaying the specified number of pieces each time, a browning setting means for setting the browning color of the food, and energizing the load by the output of the number designation switch and the output of the browning setting means. The power supply device includes an energization time determining means for determining the time, and a load energization means for energizing the load for the time determined by the energization time determining means.

Operation Based on the above structure, when roasting food such as bread,
(Separate from the browning setting) The number of pieces is specified using the number designation switch, and the energizing time to the load is automatically determined by the energizing time determining means according to the number designation and the browning setting. Moreover, when specifying the number of pieces, the number of pieces is accurately confirmed by a display means that sequentially changes and displays each time a single number-specifying switch is operated, and then the number of pieces is roasted. therefore,
Unlike conventional methods, people can easily misread the concentric circles around the G-timer knob that correspond to the number of pieces baked, and there are no errors due to timer accuracy, which can lead to overcooking of foods such as bread. This prevents the browning from becoming too thin, and ensures stable browning at all times.

Embodiment One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an automatic roasting apparatus in one embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a number designating switch, which allows the number of items to be cooked to be designated. 1
2 is a browning setting means that can set the browning of the food to be cooked. 18 is the energization time determining means, and the number designation switch 1
1 and the output from the baking setting means 12 determine the energization time. Reference numeral 14 denotes a display means that sequentially changes and displays the number designated each time the one number designation switch 11 is operated.

Reference numeral 16 denotes a load energizing means that energizes the load 16 for only the time determined by the one energization time determining means 18.

FIG. 2 is a circuit diagram of one embodiment of the present invention. In Fig. 2 1, 11 is a number designation switch, 12a, 12b
.

. . . 12c is a baking color setting switch as a baking color setting means, and the output thereof is inputted to the microcomputer 1 as an energization time determining means. 14 is a display means such as a liquid crystal display, for example, when the number designation switch 11 is 1
When pressed once, the display means 14 displays ``toast'' and ``1'', indicating that ``1 piece of toast'' has been designated. When the number designation switch 11 is pressed one more time, the display means 14 similarly displays "toast" and "2". In this way, each time the number designation switch 1 is pressed, the display of rlJ and r2J alternates. Also 12a.

When any of the browning setting switches 12b, .
, 12b, . . . , 12c determines the energization time to the heater 16 as a load.

A resistor 15a and a transistor 15b are connected to the output terminal E of the microcomputer 13, and the transistor 15b is turned on based on an output signal related to the energization time determined by the microcomputer 18. The relay relay /L'15c is connected to the transistor 15b, and when the transistor 15b is turned on, the relay relay /L'15c is connected to the transistor 15b.
5clζ current flows and relay contact 15d is turned on.

The heater 16 is connected in series with the relay contact 15d, and when the relay contact 15d is turned on, the heater 1G is energized. In this way, the microcomputer 13 outputs an output signal for the determined energizing time, thereby controlling the transistor 15b, which serves as a load energizing means.
/15C, the heater 16 is energized via the relay contact 15d to roast the bread.

FIG. 3 is a flowchart stored in the ROM of the microcomputer 18, and its operation will be explained using this flowchart. In FIG. 3, first in step 21, it is determined whether there is a switch input, and if there is no input, the process continues to wait. If there is an input, it is determined in step 22 whether it is the number designating switch '11' or the baking color setting switch '12'. If the number specification switch #11#, step 2
In step 8, it is determined whether Frag is '0' or '1'.

If Fragw is O, "toast" and "1" are displayed in step 24, and 'A-1' is displayed in step 25.
Change to CFrag w-1 and enter the value of A, which is the data for 1 energization time.If it is Fragwl, in step 26 it will display ``toast'' and ``2'', and in step 27 it will display ``A''. -2' and change to Frag-0. Step 22f, and bake setting switch '1

12c', set it to '5-1' if '12a', set 'B-2' if '12b', and set 'B-n' if '12c' to B, which is the data for one energizing time. Enter the value. Then, in step 32, it is determined whether the values of data A and B are set.

If you have not set it, return to ■. If set,
In step 33, the energization time T1 is calculated based on the value.

Then, in step 34, power supply to the load is started. When the current supply starts, the elapsed time T of 1ζ is measured.

In step 85, the process waits until the elapsed time T exceeds the energization time T1, and then in step 86 the energization to the load is stopped. Subsequently, in step 87, the data A, B and the value of Frag are cleared, and the process returns to (2).
