Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic roasting device, such as an open toaster.

2. Description of the Related Art A conventional automatic toaster of this type is an open toaster, which has a configuration E as shown in Figure 4. In Fig. 4, 1 is a timer setting means for setting the roasting time when baking bread, etc., and IA is a timer knob.
There is a scale IB around it that corresponds to the browning of the bread, etc. so that the roasting time can be set, and the energization time is set by the user turning the timer knob IA. Reference numeral 2 denotes a load and energizing means, and when the roasting time is set by the timer setting means 1, the load 8 is energized for that time. 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 turn the timer knob to set the color while looking at the scale corresponding to the color of the roasting button, and the scale does not match. There are concentric circles around the timer knob, so it's hard to see.
There was a problem that people could misread the scale and get the desired browning color wrong.

The present invention solves the above-mentioned conventional problems.

You don't have to turn the timer knob while looking at the concentric scales to set the settings.
The object of the present invention is to provide an automatic roasting device that can stably obtain roasting color without making mistakes.

Means for Solving the Problems: In order to solve the problems, the automatic roasting apparatus of the present invention has the following features:
A browning color selection means for selecting a certain browning color among several levels of browning of the food; a display corresponding to the browning color selected by the browning color selection means; The present invention includes energization time determining means for determining the energization time to the load based on the output of the color selection means, and load energization means for energizing the load for the time determined by the energization time determining means.

Function and description When roasting food such as bread, when one of several levels of browning is selected, that browning color is displayed and the energization time to the load is automatically adjusted accordingly. Since the browning color display can be confirmed without mistaking the browning color display, the one energization time can also be determined reliably. Since there is no need to adjust the timer knob to the formed scale to set the time, it is possible to prevent misreading of the scale and the wrong browning of food such as bread.

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 browning color selection means for selecting one of several levels of browning of the food.

Only one color can be selected.

Reference numeral 12 denotes a baked color display means for displaying only the baked color selected by the baked color selection means 11. Reference numeral 18 denotes an energization time determining means, in which the energization time is memorized for each of the several levels of browning of the food, and when one of the browning colors is selected by the browning selection means 11, the load is applied for the corresponding energization time. The load 15 is energized by the energizing means 141ζ.

FIG. 2 is a circuit diagram of one embodiment of the present invention. In FIG. 2, the browning selection switch IIA and the resistor 11B constitute a baking color selection means, and each time the baking color selection switch IIA is pressed, the baking color can be selected in several stages fζ sequentially. The energization start switch 16A and the resistor 16B constitute energization start means, and their outputs are fed to the microcomputer 181ζλ as energization time determining means. Reference numeral 12 constitutes a baking color display means using a liquid crystal display, and liquid crystals 12A to 12J are turned on depending on the type of baking color, which has several levels.

When the color is the lightest, only the 12A liquid crystal is lit, and when the color is the darkest, all the liquid crystals from 12A to 12J are lit. When the switch IIA is pressed once, the liquid crystal 12A lights up, and when the switch IIA is pressed once more, the liquid crystals 12A and 12B are turned on.

In the same way, each time you press the browning selection switch, 12A to 12
It is possible to turn on up to J in sequence, and only one baked color is displayed. A resistor 14A and a transistor 14B are connected to the output end of the microcomputer 18, and the output signal turns on the transistor 14B.

Transistor 14Blζ is connected to V-coil/I/14C, and when transistor 14B is turned on, current flows through Lecoi 1v14C.

Relay contact 14D turns on. The heater 15 is connected as a load in series with the relay contact 140, and when the relay contact 14D is turned on, the heater 16 is energized.

In this way, while looking at the baking color display means 12, press the switch 11.
When you press A to turn on the lights in sequence, set the desired browning color, and press the switch 16At-, the microcomputer 18 will turn on E for each browning time out of the stored energization time.

By outputting an output signal only during the energization time corresponding to the set amount of browning, the transistor 14B, relay coil 14C, and one IJ sill 14 as load energization means are used.
Electricity is applied to the heater 15 via D to roast bread or the like.

FIG. 8 is a flowchart stored in the ROM of the microcomputer 18, and its operation will be explained using this flowchart. In FIG. 8, 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 the input is the browning selection switch IIA or the energization start switch 16A. If it is the baking color selection switch IIA, it is determined in step 23 whether or not all of the liquid crystals 12A to 12J are lit.

If all LCDs are lit, in step 24 LCD 1
2A to 12J are all turned off, and 'Fr' is turned off in step 25.
Set ag' to '0゛ and return to ■. Furthermore, if all the liquid crystals are not lit in step 23, the liquid crystal is increased by +1' in step 26 and turned on (for example, the second
In the figure, when only 12A is lit], 2A and 1
2B). And in step 27 'Fra
Increase 〆 by plus 1' and return to ■. After checking the changes in the browning color display, press the browning color selection switch IIA to set the desired browning color.

Then, when you want to energize the load (ζ and roast bread or the like), press the energization start switch 16Alt. Then, in step 22, this is detected, and in step 28.

The load energization time T1 is determined from the 'Frag' number 1 at that time. Then, in step 29, [ζ is output] so as to energize the load. When energization is started, the elapsed time T since the start is measured, and in step 30, the elapsed time T and the load energization time T1 are compared, and when T reaches T, step 8
Step 1 stops power supply to the load, and returns to step ①.

Effects of the Invention According to the present invention, by operating the baking color setting means,
You can check the desired browning color by looking at the browning color display for one of the several levels of browning, and at the same time the energization time for the load is automatically determined. There is no need to set the time by setting the timer knob according to the scale formed in concentric circles according to the browning, so there is no chance of misreading the scale and overcooking the food.

It is possible to prevent the product from becoming too thin, and it is possible to obtain a stable and good browning color.
