DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for controlling the cooking time and the roasting time of toast etc. using an oven toaster used in ordinary households.

[0002]

2. Description of the Related Art Conventionally, a mechanical timer such as a mainspring timer and an electronic timer such as a CR timer have been used for setting a bread toasting time in an oven toaster.

In recent years, oven toasters have been made which use a microcomputer instead of a mainspring timer or a CR timer to control the toasting time of bread by a program. The configuration of such an oven toaster is shown in FIG.
6 and 7. FIG. 5 is a sectional view of the main body showing the configuration of the oven toaster.
Is arranged, and the food 5 placed on the mounting table 4 is heated by the heaters 2 and 3 and toasted.
Reference numeral 6 denotes a printed wiring board to which a microcomputer and the like are attached.

FIG. 6 is a block diagram showing an electric configuration. A relay contact 8 is connected to the heaters 2 and 3 so that the heaters can be turned on and off. 9 is a relay drive circuit. Input means 10, 11, 12, and 13 are tact switches and the like, and have functions such as time setting and start / stop.

[0005] Reference numerals 14 and 15 denote display means comprising light-emitting diodes, which light up during operation to indicate the operation state. 16 is
Numerical display means such as an LCD for displaying time is used to display time when the timer is operating. Reference numeral 17 denotes a variable resistor provided for inputting the level of the toasted color. This variable resistor corresponds to the printed board 6 shown in FIG.
And is operated by a user using a knob.

FIG. 7 is an external view showing the configuration of the operation section. A numeric display section, input means, a knob 18 for operating a variable resistor, and the like are provided on the front of the lower portion of the main body.

[0007]

However, in the above configuration, an opening for a knob for operating the variable resistor is formed in the operating section of the main body, from which water invades or is cleaned. It had disadvantages such as difficulty.
In addition, since there is no space in the main body for setting a plurality of variable resistors, only one variable resistor is provided. Therefore, if the optimum level of the completed cooking differs depending on the type of cooking, reset the value one by one. It was necessary and was inconvenient.

The present invention has been made to solve such a problem, and has a structure in which an opening of a main body is eliminated, water does not enter, and cleaning is easy, and an optimum level of completed cooking varies depending on a type of cooking. Even in such a case, it is an object of the present invention to provide an easy-to-use cooker that does not need to be reset.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a heater provided in a main body, and an on-off heater.
Relay contact to operate and the relay drive circuit to operate the relay
Path and switch contacts provided on the power supply of the relay drive circuit
A switch connected to a power supply of the relay drive circuit.
Input means that turns on and off at the same time as
Level setting means for setting the level, and the finished
Display means for displaying the level and the completed level
Storage means for storing the level of the finished cooking.
Is stored for each menu that can be cooked.
The storage device is a control device for an oven toaster using a non-volatile memory .

[0010]

[0011]

[0012]

According to the above construction, the setting means for setting the level of the completed cooking, which has conventionally been constituted by a variable resistor, is constituted by a switch and a display means, and has no opening. It can be configured. Further, since the completed cooking level is stored for each cooking menu, the optimum level is read out from the storage means every time an operating menu is selected, so that it is not necessary to reset the completed cooking level each time.

[0013]

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

FIG. 1 is a block diagram of an oven toaster showing an embodiment of the present invention. Reference numerals 19 and 20 denote heaters attached to a main body, and 21 denotes heaters 19 and 20.
, A relay drive circuit, and 23 a microcomputer for controlling the operation. 24 and 25 are level setting means for setting the finished level, 26 is a level display means for displaying the finished level composed of LEDs, and 27 is
This is storage means for storing the level of the baked color.

In this configuration, the operation is as follows.
First, in the case of toast, if the operation is the first operation when the toast operation is selected by the switch 29, the medium level first appears as a standard state. When the level is changed, the level of the burn color is set by the level setting means 24 and 25. The set level is displayed by lighting one of the LEDs of the level display means 26. Then, the set finished level is stored in the storage unit 27 corresponding to the toast.

The level can be set and stored for each operation other than the toast in the same manner. After setting the level, when the switch 30 is operated, the heaters 19 and 20 are turned on for a time corresponding to the level, and the cooking is performed.

Once the completion level of each cooking is stored, as shown in the flowchart of FIG. 2, every time the menu to be operated is selected, the previously set completion level of the cooking is read out from the storage means. , There is no need to reset.

FIG. 3 is a block diagram of an oven toaster according to an embodiment of the present invention. In FIG. 3, a switch having contacts 31 and 32 is added as a power switch to the configuration of FIG. The contact 31 turns off the power of the relay drive circuit, and the contact 32 inputs a power off state to the microcomputer. Therefore, when the power is off, the power of the relay drive circuit is shut off, and the microcomputer is in a standby state. However, as long as the power outlet is connected, the data in the storage unit 27 is not lost.

If a non-volatile memory is used as the storage means 27, the data is not lost even when the power is turned off. Therefore, even if the power outlet is disconnected, the level of the previously completed cooked food can be set by the menu selection when the power is reused. The configuration is set for each. FIG. 4 is an enlarged view of a main part showing a switch panel of the oven toaster, and shows a configuration in which the finished cooking level is set by LEDs and input switches 24a and 25a instead of the conventional variable resistor.

[0020]

As described above, the control device of the oven toaster of the present invention allows the setting of the level of the completed cooking to be performed.
From the variable resistor, the level setting means for setting the level of the completed cooking, the display means for displaying the level of the completed, and the storage means for storing the level of the completed, the opening of the main body In addition to being in a configuration that is easy to clean, there is no intrusion of water, etc., and even if the optimum level of completed cooking differs depending on the type of cooking, it is not necessary to reset each time, making it a convenient cooker. There is great value.
