Abstract

PURPOSE:To prevent the occurrence of too baking or insufficient baking, by a method wherein, when a material to be cooked, e.g. bread, is baked, by setting the number of the materials to be cooked and setting baking color, a time of energization of a load is automatically decided. CONSTITUTION:By means of the number of materials to be cooked set by num ber setting switches 11a and 11b and a baking color set by baking color setting switches 12a, 12b,..., 12c, a time of energization to a heater 16, being a load, is decided by a microcomputer 13. By outputting an output signal only for the decided energization time from the microcomputer 13, a heater 16 is ener gized through a transistor 15b, a relay coil 15c, and a relay contact 15d, all serving as a load energizing means, to bake bread.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic roasting device used, for example, in an open toaster.

2. Description of the Related Art A conventional automatic roasting device of this type is an open toaster, which has a configuration as shown in FIG. Fourth
In FIG. 1, reference numeral 1 denotes a timer setting means, and the energization time is set by the user turning the timer knob 1a Cζ. 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 ta, corresponding to the number of pieces on the number display section 1b,
A scale IC is provided to indicate the energization time depending on the browning of bread, etc. 2 is a load energizing means, and when the energizing time is set according to the number of baked colors Gζ by the timer setting means II, the load 8 is energized for that time. Roast etc.

Problems to be Solved by the Invention With the conventional configuration as described above, when roasting bread, etc., the timer knob is set by turning the timer knob while looking at the scale according to the number of pieces to be roasted. Therefore, there was a problem in that one could mistakenly see the scale of the baked color corresponding to the different number Gζ.

The present invention solves the above-mentioned conventional problems.

An object of the present invention is to provide an automatic roasting device that can prevent over-baking or over-baking by checking the scale of the browning color of bread, etc. to be roasted without making a mistake. It is something.

Means for Solving the Problems In order to solve the problems described above, the automatic roasting apparatus of the present invention includes a number designation means for designating the number of items to be cooked, and a display of the number designated by the number designation means. a display means for setting the browning of the food, a browning setting means for setting the browning color of the food, an energization time determining means for determining the energization time to the load based on the output of the number specifying means and the output of the browning setting means; and load energizing means for energizing the load for only the time determined by the time determining means.

Effect With the above configuration, when roasting food such as bread, the number of pieces is specified separately from the browning setting, and the energization time to the load is determined by specifying the number of pieces and the browning setting. The number is automatically determined from the means (ζ), and the number of pieces is confirmed by the display means.

To roast. Therefore, it is possible to prevent a person from misreading the scale corresponding to the baking color Cζ for each number of pieces and from overcooking bread or other foods such as bread or baking them too thinly, as in the past.

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, numeral 11 is a number specifying means, which allows the number of items to be cooked to be specified. Reference numeral 12 is a browning setting means for setting the browning of the food to be cooked. 18
is an energization time determining means, and the energization time is determined by the output tube from the number-of-pieces designating means 11 and the baking color setting means 12. 1
Reference numeral 4 denotes a display means for displaying the number specified by the number specifying means 10. Reference numeral 16 denotes load energizing means, which energizes the load 16 only for the time determined by the energizing time determining means 13.

FIG. 2 is a circuit diagram of one embodiment of the present invention. In Fig. 2, lla and llb are number designation switches as number designation means, 12a, 12b, ... 12c are baking setting switches as baking color setting means, and their outputs are microcontrollers as energization time determining means. It is input to computer p18. 14 is a display means using a liquid crystal display; for example, when the number designation switch lla is pressed, the 1 display means 14 displays "toast" and "1";
Displays that #1 piece of toast has been specified. When the number designation switch llb is pressed, the display means similarly displays "toast" and "2". 12a
, 12b, -, 12c, the microcomputer 1B selects the number specified by the quantity designation switches lla, llb and the baking setting switches 12a*12b+...

Heater 16 as a load due to the browning set in 12c
Determine the energization time. A resistor 15a and a transistor 15b are connected to the output terminal of the microcomputer 18, and the transistor 15b is turned on by an output signal related to the energization time ζ determined by the microcomputer 18. Transistor 15b f This is a relay car/
M15c is connected, and when the transistor 15b is turned on, a current of A/15cf flows and the relay contact 15d is turned on. Heater 16 is relay contact 15d
When the relay contact A 15a is turned on, the heater 16 is energized.

In this way, the microcomputer 13 outputs an output signal only for the determined energizing time, so that the transistor 15b and the relay coil 15b as load energizing means are connected to each other.
5cs The heater 16 is energized via the relay contact 15d to roast bread or the like.

FIG. 8 is a flowchart stored in the ROM of the microcomputer 13, and its operation will be explained using this flowchart. In FIG. 8, first at step 21.

It determines whether there is a switch input, and if there is no input, it continues to wait. If there is an input, go to step 22 and press 1 quantity designation switch '11# Calcination color setting switch #1r
determine whether If the number designation switch 11' is selected, it is determined in step 28 whether it is lla or llb. '11
If it is a', in step 24 "toast" is displayed and "1" is displayed.
'' is displayed, and in step 25, the value of A, which is data on the energization time, is entered as 'AAl1. If it is 'llb', 'toast' and '2' are displayed in step 26, and 'A-2' is displayed in step 27. In step 22, if it is the baking setting switch '12', step 28 and steps 29, 80, . . . al,
Determine whether it is '12a' or '12baka'=-='12c', and if it is '12a', select 'B-1'.

'12b' is 'B-2' binding 6 '12C' is 'B'
-n' and enter the value of B, which is the data of the energization time.

Then, in step 82, it is determined whether the values of data A and H have been set.

If you have not set it, return to ■. If set,
In step 88, the energization time TI is calculated based on the value.

Then, in step 84, power supply to the load is started. As soon as the power supply starts, the elapsed time T is measured.

In step 85, the process waits until the elapsed time T exceeds the energization time TI, and when it does, the energization to the load is stopped in step 86. Subsequently, in step 87, the values of data A and B are cleared, and the process returns to (2).

Effects of the Invention As described above, according to the present invention 1, the number of items to be cooked is specified separately from the setting of the browning color, and the energization time to the load is automatically set based on the specification of the number of pieces and the setting of the browning level. can be determined,
In addition, the number of pieces can be confirmed by the display means, so there is no need for people to misread the scale according to the number of pieces baked, unlike in the past, and avoid overcooking the food. This can prevent things like being too thin.
