Abstract

PURPOSE:To simplify correction of an erroneously set cooking course and restarting after the correction by ensuring that when a new cooking course is inputted within a predetermined period of time after a cooking-starting instruction is given, stored data is changed according to the new cooking course, and cooking is performed. CONSTITUTION:When a new cooking course is inputted by pressing another course key within a predetermined period of time Ta after an input is given through a start key 7, a course display on a display part 6 and data stored in a RAM 11 provided as a storage means are changed according to the new cooking course. After the lapse of the predetermined period of time Ta, a controlling part 9 sets and recognizes a cooking sequence corresponding to the cooking course stored in the RAM 11 at that moment, and controls a magnetron 2 according to the set cooking sequence while detecting the temperature of a material being heated on information from an IR sensor 8, whereby cooking by heating is performed. Thus, correction of an erroneously set cooking course and restarting after the correction can be performed easily, with favorable convenience in use.

Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a cooking device such as a microwave oven.
Conventional technology In a microwave oven where multiple automatic cooking courses are available, for example, when milk is about to reach its final stage, it may accidentally start heating in the "Milk" course, even though it should have been used. This is especially likely to happen to people who are not used to using a microwave oven or when operating it in a hurry, such as inputting the cooking course incorrectly.
If you notice your mistake after you start cooking, try again! In the cooker disclosed in Japanese Utility Model Application Publication No. 57-130101, in which it is necessary to input the IIJI course, in the above case, in order to re-enter the cooking course money and restart full heating, first press the ``Stop hJ key''. Completely stop heating, press the [Stop] key again to clear the information stored in the control means, and then press the [Milk] key to select the cooking course.
It requires the user to press the "Start" key, which requires manual effort four times, making the operation troublesome.7tnC1

The control unit +91 consists of a so-called microcomputer, etc., and its ROMn (* stores 9 cooking sequences corresponding to each cooking course, and the i-mat control unit +9+ realizes the cooking sequence by executing 10 grams. has RAMCl1l which functions as a storage means as described later.0 Figure 2 shows a flowchart of the microcomputer of the control unit 191. The execution of 10 khums is started, and the cooking course selected in S1 step 1 is stored in the RAM [lυ, and is also displayed on the display section (6I) in S2 step 1.

l Next, when the start key 171 is pressed and an instruction to start cooking is given, the process proceeds from the 83rd step to the 84th step/1. In the S4 step, t is a counter that is counted up from when the start key 17+ is input. And-
Go to S4 S9 Step 1 loop and press the start key (7
+ Count all the elapsed time from the time of input n Next, the magnetron 12+ starts driving in S5 step 1 and heating is performed, but the heating here is not based on the detection result of the infrared sensor (8!). □Next, at step 86, it is determined whether another course key has been pressed, and if it has not been pressed, proceed to S9 step 1. In S9 step y1, from the start key + input at S3 step 1 After one step time Ta has elapsed, it is fully determined whether they are friends or not, and if it has elapsed as shown in t)'ra, proceed to step 81 (J; if it has not elapsed, return to step S4 J1. In other words, make a determination in step 36. If no cooking course is entered, S
The loop from steps 4 to 56-S9 is repeated until a certain period of time Ta has elapsed, and the process advances to step 1 in S10.

However, after the start key (7) is input, Ta
If another course key is pressed within the 86th step to input a new cooking course, the course display on the display section 161 and the memory contents of the RAM συ as the middle storage stage will be changed to that new friend's key in steps S7 and S8. The steps S4 and S9 to be changed to the cooking course 1 correspond to the timing means, and the steps S6 to S8 correspond to the changing means. After a certain period of time Ta has passed, the process advances from step S9 to step 1 of step 810.In step SIO, the control unit (91 recognizes the cooking sequence corresponding to the cooking course stored in RAMσD at that time) and goes to step 1 of all The temperature of the object to be heated is detected using information from the infrared sensor t8+, and the magnetron (
