Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cooking appliance with a fermentation cooking function.

[Technical background of the invention]

Generally, this type of cooking appliance, such as a microwave oven, is shown in FIG. Reference numeral 1 denotes a main body of the microwave oven, and a door 2 is pivotally supported on the front surface of the main body 1 so as to be freely openable and closable, and an operation panel 3 is provided. A heating chamber (not shown) is provided within the main body 1 corresponding to the door 2. The operation panel 3 is provided with a display 4, a cooking type setting key 5, a cooking condition setting key (including a numeric keypad) 6, a power switch key 7, a cooking start key 8, etc. in order from the upper part to the lower part. By operating the cooking type setting key 5, microwave cooking, oven cooking, grill cooking, fermentation cooking, etc. can be performed as appropriate.

By the way, fermentation cooking is carried out by maintaining the temperature inside the heating chamber at a low temperature, e.g. 38°C, and when the heating chamber is still at a high temperature (e.g. immediately after microwave cooking, oven cooking, or grill cooking).
This is not possible if the temperature is above 60°C, as the yeast will die.

To deal with this, the following control has conventionally been performed. That is, as shown in FIG. 2a, when the fermentation cooking key 5a of the cooking type setting key 5 is turned on, the character "fermentation" is displayed on the display 4, and a code corresponding to fermentation cooking is also displayed. . Next, when the fermentation cooking time is set using the cooking condition setting key 6, the set cooking time is displayed on the display 4, as shown in FIG. 2b. Finally, when the start key 8 is turned on, fermentation cooking starts. At this time, the temperature in the heating chamber is detected, and if the temperature in the heating chamber is higher than a certain value, for example 60℃ or higher, cooking is immediately stopped, and the second As shown in FIG. C, the character "E" is displayed on the display 4. Therefore, the user sees the display "E" and realizes that the temperature in the heating chamber is still too high for fermentation cooking, and opens the door 2 to take out the food from the heating chamber. Note that the flowchart in FIG. 3 shows this control.

[Problems with the background art] However, detecting the temperature in the heating chamber at the time when the start key 8 is turned on means that the food is necessarily stored in the heating chamber at this time. If the temperature exceeds 60°C, the user has to take out the food once placed, which is extremely troublesome for the user.

[Purpose of the invention]

This invention was made in view of the above-mentioned circumstances, and its purpose is to accurately and timely determine whether fermentation cooking is possible or not prior to operating the start key. It is an object of the present invention to provide a method for controlling a cooking appliance that can notify and improve operability and reliability.

[Summary of the invention]

This invention detects the heating chamber temperature when the fermentation cooking setting key is operated, and if the heating chamber temperature is above a certain value, notifies the heating chamber temperature and disables the operation of the start key to perform fermentation cooking. is prohibited.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. However, in the drawings, the same parts as in FIGS. 1 and 2 a, b, and c are given the same reference numerals, and detailed explanation thereof will be omitted.

FIG. 4 shows the main parts of the control section of the microwave oven. 1
0 is a temperature sensor in the heating chamber, such as a thermistor, and a DC voltage V _d is applied to this thermistor 10 via a resistor 11. The voltage obtained at the interconnection point of the thermistor 10 and the resistor 11 is connected to an analog/digital converter (hereinafter referred to as A/D) via the resistor 12.
(abbreviated as converter) 13, where it is converted into a digital signal. This digital signal is supplied to the microcomputer 14. The microcomputer 14 includes a key group 1 consisting of the cooking type setting key 5, cooking condition setting key 6, power switch key 7, and cooking start key 8.
5 is connected, and the display 4 is also connected. That is, the microcomputer 14
Heating control is performed in accordance with the heating chamber temperature based on commands from the key group 15 and the output of the A/D converter 13, and necessary information is displayed on the display 4.

Therefore, as shown in the flowchart of FIG. 5, when the user turns on the fermentation cooking setting key 5a to execute fermentation cooking, the microcomputer 14 responds by executing a cooking program for fermentation cooking. At the same time, the character "fermentation" and the code corresponding to fermentation cooking are displayed on the display 4. At the same time, microcomputer 1
4 detects the temperature in the heating chamber using a thermistor 10, and if the temperature in the heating chamber is 60°C or higher, which is not suitable for fermented cooking, the display 4 will display "60°C" as shown in FIG.
℃'' temperature display (notification) is flashed, and subsequent cooking time setting commands by operating the cooking condition setting key 6 and cooking start commands by turning on the start key 8 are not accepted.In other words, fermentation cooking is not possible. In addition, execution of fermented cooking is prohibited.However, if microwave cooking, oven cooking, or grill cooking is set with the cooking type setting key 5, the control immediately shifts to that mode.

On the other hand, if the temperature in the heating chamber is 60° C. or lower, the microcomputer 14 completes the cooking time setting and turns on the start key 8 to execute fermentation cooking.

In this way, the temperature in the heating chamber is detected when the fermentation cooking setting key 5a is turned on, and if the temperature in the heating chamber is not suitable for fermentation cooking, a notification is made to that effect, and the operation of the start key 8 is disabled. By prohibiting fermentation cooking, users can determine whether fermentation cooking is possible or not in a timely manner before placing the food in the heating chamber, and if it is not possible, the user can It is very convenient as there is no need to take it in and out. In other words, operability and reliability can be improved.

In addition, in the above example, cooking was made impossible when the temperature in the heating chamber was 60°C or higher, but it is not necessarily limited to 60°C or higher, and it may be changed as appropriate depending on various circumstances. Just set it. In addition, the present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without changing the gist.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to notify the user whether fermentation cooking is possible or not in a timely and accurate manner prior to operating the start key, thereby improving operability and It is possible to provide a cooking device control method that can improve reliability.
