[Summary of the invention]

This invention is a heavy-duty sensor-equipped cooker that has a weight sensor inside the cooker body, and is equipped with a heavy-duty four-sensor unit that transmits weight data independently from the cooker body. , this one recitation sensor unit or the weight sensor type 545 data is selectively displayed on the display section.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In Fig. 1, J is the main body of the weight-sensing telephone call center, and on the front side of this main body, a door 2 is pivotably supported so that it can be opened and closed freely, and an operating panel 3 is provided. Force yourself. A heating chamber 4 is provided in the main body 1 corresponding to the door 2, and a turntable 5 for placing the food to be processed is provided in the heating chamber 4. The shaft of the turntable 5 passes through the bottom plate of the heating chamber 4, engages with the turntable drive motor 6, and comes into contact with the quantity sensor 7.

When the food to be cooked is placed on the turntable 5, its weight is applied to the weight sensor 7.

The operation panel 3 also includes a digital display section 8, a lamp 9 which is a no-load state alarm section, a 97110% cooking condition setting key I and a % cooking start key 12 which is a main body side weight display alarm section. etc. are arranged from the upper part to the lower part.

On the other hand, 13 is a weight sensor unit, which is independent from the main body 1 and has a weight 1 sensor 14, a transmission circuit 15, etc. inside.

FIG. 2 shows the control circuit. First, in main body 1, 20
A microcomputer is a main control section, and the display section 8, lamps 9 and 10, and heating operation section 2 are connected to this microcomputer 20. This heating operation section 21 is a high frequency generator such as a magnet l-.

The main component is the main component (not shown). Further, a weight sensor 7 and a receiving circuit 23 are connected to the microcomputer 20 via an A/D (analog/digital) controller 22 . This receiving circuit has 24 pieces, has 7 antennas 2.9a, and has 1 weight + 1 sensor unit.
It receives the weight data sent from.

1, Jukai Sensor Units) 7. ? fd, power supply 24]
7, and the data obtained by the weight sensor 7 is transmitted to the main body 1 by radio waves by a transmitting circuit 15 having an antenna 75a.

Next, the operation of the above-described configuration will be explained. First, as shown in FIG. If not, no message is displayed on the display section 8, and the lamp 9 is lit to notify the no-load state.

As shown in No. 311 (b), when the food to be cooked A is placed only on the turntable 5, the weight of the food to be cooked A is measured by the weight sensor 7, and the weight data is displayed on the display section 8. When the door 2 is closed and the cooking start key 12 is turned on in this state, the heating operation section 2 is activated and high frequency waves are supplied into the heating chamber 4. In this case, the microcomputer 20 controls the heating operation section 21 based on weight data obtained by the weight sensor 7.

In other words, optimal cooking according to the weight of the food to be cooked A is performed.

As shown in FIG. 3(c), when the food to be cooked A is placed only on the weight sensor unit J3, the weight of the food to be cooked A is measured by the weight sensor unit 13 and the weight data is sent to the main body 1. Ru.

The microcomputer 20d displays the received weight data on the display section 8. Therefore, if the weight sensor unit 13 is used in this way, it is possible to easily measure the weight of an object that cannot fit inside the heating chamber 4. Further, even when the weight of the food is slightly reduced during preparation for cooking, there is no need to draw out the food in the heating chamber 4, which is convenient. In this case, since the heating chamber 4 does not contain any heat, the lamp 9 lights up to notify the no-load state. Also, even if you turn on the cooking start key 12 in this state,
Cooking will not start.
