Description

DETAILED DESCRIPTION OF THE INVENTION An object of the present invention is to provide a cooking device that is dramatically improved in ease of use and convenience. especially,
The aim is to improve the operability of cooking devices such as microwave ovens, which require a set heating time.

In conventional microwave ovens, the heating time is set on a timer depending on the amount of food. but,
It is troublesome to weigh each food item on a regular scale, convert it into heating time, and then set the timer. was common. In such a case,
Naturally, there were many failures such as insufficient heating or overheating, and results that satisfied the users could not be obtained.

Therefore, the present invention provides a cooking device that is easy to use and does not fail. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing an embodiment of the present invention. Reference numeral 1 denotes the main body of the microwave oven, and there is a door 2 on the front that can be opened and closed freely, and when the door 2 is opened, a heating chamber 3 can be seen. Reference numeral 4 denotes an operation section on the side of the device, which is composed of a numeric display section 5 and a key input section 6. Reference numeral 7 denotes a control section for controlling the microwave oven provided inside the container. Reference numeral 8 denotes an antenna protruding from the container body, 9 a weighing scale independent of the container main body 1, and an operating section 10 of the weighing scale;
An indicator scale 11 and the like appear on the surface. 12 is an antenna extending outside from the weight scale 9 side. 1
3 is the food, and 14 is its container. Figure 2 a, b
shows an enlarged view of the weight scale 9. 15 is a power switch, and 16 is a container key. When only the container 14 is placed on the mounting table 18 and the container key 16 is pressed, a signal corresponding to the weight of the container 14 is output to the antenna 1.
Sent from 2. Reference numeral 17 denotes a total amount key. When a container 14 containing food 13 is placed on a mounting table 18 and the total amount key 17 is pressed, a signal corresponding to this weight is transmitted from the antenna 12. That is, the inside of the weight scale 9 has a structure as shown in FIG.
Reference numeral 21 denotes a mechanical part of the weighing scale made of a spring plate, etc., which produces an amount of deflection proportional to the weight placed on the mounting table 18. Reference numeral 22 denotes a weight sensor that converts the amount of deflection mentioned above into an electrical signal, and can be specifically realized by a load cell, a piezoelectric element, a pressure transformer, or the like. 23 is an amplifier, and 24 is an A/D converter. 25 is a controller and a container key 16;
The contents of the A/D converter 24 are controlled to be transmitted to the modulator 26 in response to instructions from a key input section 29 consisting of the total amount key 17. 27 is a power source, which is made by taking in a battery or a commercial power source.

The weight signal modulated by the modulator 26 is transmitted to the antenna 1.
2, is received by an antenna 8 provided on the main body, and is demodulated by a demodulator 29 into the original weight signal form. 30 is a control unit having a timer function, calculation function, etc., which automatically calculates the heating time and heating output from the instruction from the operation unit 4 of the main body and the weight signal input from the demodulator 29, and It controls a heating device 31 including a microwave oven magnetron and the like.

FIG. 5 shows an enlarged view of a portion of the operating section 4.

Place only the container 14 on the scale 9 and press the container key 16.
When pressed, the weight of the container 14 is displayed on the display section 5. Next, when the food 13 is placed in the container 14 and the total amount key 17 is pressed, the net weight of the food 13 is displayed on the display section 5. The user instructs whether the food 13 is a vegetable or meat from the operation section 4 of the main body of the container by pressing the key 3 corresponding to each food.
2 and 33, the control unit 30 comprising a microcomputer etc. performs weight-heating time conversion as shown in FIG. Its contents are displayed.

As explained above, the weighing scale 9 not only transmits the weight of the food 13 to the body of the vessel in the form of a wireless signal, but also functions completely independently of the body of the vessel as shown in Fig. 2b. It can also be used as a regular scale. 19 is an indicator hand, and 20 is a zero point adjustment knob.

As explained above, according to the present invention, the following effects can be expected.

(1) Place the scale on the cooking table where you cut or chop food, input the weight information of the food into the control panel of the cooker, and the heating time will be automatically set. , very convenient and undercooked,
There is no need to worry about overheating. It is especially convenient to use because it does not matter where you hold the scale in the kitchen.

(2) The weighing scale is convenient because it can be used independently of the cooking device itself.

Claims (1)

[Scope of Claims] 1. A weighing scale having a function of measuring the weight of food, etc., displaying the value, and transmitting the value wirelessly as a weight signal is provided separately from the main body of the container, and The device has a function of receiving the weight signal transmitted from the weighing scale, a key input section for the user to key-in food information, and a function to automatically heat the food based on the received weight information and key-input food information. A cooking appliance comprising: a control section for calculating time and heating output and controlling a heating device; and a display section for displaying the heating time and heating output. 2. The cooking appliance according to claim 1, further comprising a weighing scale capable of measuring weight even if it is separate from the cooking appliance main body.
