Abstract

PROBLEM TO BE SOLVED: To enable an easy grasp of the rotation angle of a turn table from outside by estimating the rotation angle of the turn table on the basis of the time of one revolution of the turn table and counts of count means, and displaying the rotation angle obtained by the estimation. SOLUTION: With starting of cooking, a magnetron is driven, and a turn table is started to be rotated (S1). Then, rotation time of the turn table is estimated on the basis of set heating time and one revolution time of the turn table stored in a memory (S2). For example, if the heating time is set at 45 seconds and the one revolution time at 010 seconds, there is estimated 50 seconds that is longer than 45 seconds and a minimum multiple of 10. Counting down is started (S3), and following this the rotation angle is displayed (S4, 5). For the display of the rotation angle, for example, it is displayed 8 times during one revolution with the lapse of time. More specifically, there is displayed a change in the angle of 360/8 degree for each 10/8 seconds.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a heating cooker such as a microwave oven having a turntable.

[0002]

2. Description of the Related Art There is a heating cooker such as a microwave oven having a turntable which is always stopped at the same position as when the turntable is stopped (disclosed in Japanese Patent Laid-Open No. 82490/1990). , So that taking out the food can be done easily.

[0003]

However, in the case of hurrying, the food may be taken out before the heating is completed, and in such a case, the food may be taken out by looking into the heating chamber. When the heating chamber was filled with steam, it was difficult to confirm the rotation position. Further, the same problem as above occurred when taking out the food when stirring the food during heating. If it takes a lot of time to take it out during heating, the temperature inside the heating chamber lowers, and the heating efficiency lowers.

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to easily grasp the rotation angle of a turntable from the outside.

[0005]

According to a first aspect of the present invention, in a heating cooker including a turntable in a heating chamber, a counting means, a time for one turn of the turntable, and the counting means are provided. It is configured to include a calculation unit that calculates the rotation angle of the turntable from the count number and a display unit that displays the rotation angle obtained by the calculation.

According to a second aspect of the present invention, in the first aspect of the present invention, the rotation angle calculation and the rotation angle display associated therewith are performed a plurality of times during one rotation of the turn tail.

According to a third aspect of the present invention, in the first or second aspect of the invention, the display means is a cooking time or a cooking menu display portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a schematic block diagram of the present invention. 1 is a control unit including a microcomputer for controlling the microwave oven and a memory, 2 is a turntable drive circuit unit, 3 is a display unit for displaying cooking time and turntable rotation state, and 4 is a cooking condition input Key input means 5 for operating the heating drive circuit portion for driving a heating source such as a magnetron. The control section 1 constitutes the counting means and the computing means of the present invention, and the display section 3 constitutes the display means.

The operation will be described with reference to the flowchart of FIG. As the cooking is started, the magnetron is driven and the turntable starts to rotate (step 1). Next, the turntable rotation time is calculated from the set heating time and one turntable rotation time stored in the memory. Now, assuming that the heating time is 45 seconds and the one rotation time is 10 seconds, 50 seconds, which is the smallest multiple of 10 and is larger than 45 seconds, is calculated.

Then, the countdown is started (step 3), and the rotation angle is displayed accordingly (steps 4 and 5). The rotation angle is displayed eight times over one rotation, for example. That is, 360 / every 10/8 seconds
Show that the 8 degree angle changes.

FIG. 3 shows a display example of the cooking time on the display unit 3, and by using the numeral display body 10 at the left end, as shown in FIGS. 1 to 8 segments are lit, and different angles are displayed. If the food is to be taken out halfway, it may be taken out at the display timing of (H), which is the position at the start of rotation of the food.

This display operation is continuously performed until the rotation of the turntable is stopped even after the heating is completed.

In the above-described embodiment, the number of the number display bodies 10 on the display unit 3 is set to 5 so that the display is always performed. However, the number is set to 4 and the cooking time display is 3 digits display after 10 minutes. After this is done, the leftmost numeral display 10 may be used. Further, the display unit 3 may normally display the cooking time, and may display the rotation angle only when there is an operation command.

[0014]

As described above, according to the first aspect of the present invention, the rotation angle of the turntable can be easily seen from the outside by looking at the display portion. Also in this case, the food can be taken out at a position where it is easy to take out without looking into the heating chamber.

Further, according to the second aspect of the invention, the rotation angle is displayed a plurality of times during one rotation, so that it is easy to take out the food at a position where it is easy to take out while confirming it. You will be able to.

Further, according to the invention of claim 3, since the rotation angle display of the turntable is displayed on the cooking time display portion, the invention of claim 1 or 2 is realized with a simple structure. .
