Abstract

PROBLEM TO BE SOLVED: To easily perform heating cooking by reading a bar code of food arranged in a heating chamber, and controlling heating operation on the basis of its read content. SOLUTION: Food 5 is placed on a turntable 4 in a heating chamber 1, and a door 2 is closed, and when start input is performed by an operation part, a motor 13 is driven by a control part, and opens a shutter 12, and an illuminating lamp 11 is lighted. Therefore, a bar code part of the food 5 is read by a camera 10, and when its read contact is inputted to the control part, the shutter 12 closes, and the illuminating lamp 11 is turn off, and a motor 3 and a magnetron 6 are actuated for the time corresponding to the food 5, and heating cooking is performed. Therefore, heating cooking can be performed without setting heating time corresponding to the food 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the arrangement of bar code readers in a heating and cooking device such as a microwave oven.

[0002]

2. Description of the Related Art For example, in Japanese Unexamined Patent Publication (Kokai) No. Hei 2-121294, an electronic device which reads a bar code attached to food and indicates the content of the food by a bar code reader and performs a cooking operation at a time set based on the read content The range is shown. With such a configuration, the cooking can be performed without setting the heating time corresponding to the food.

[0003]

However, in the above-mentioned configuration in which the contents of food are read by using the bar code reader, the operation is troublesome and the bar code reader is lost or damaged. There was a point.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to enable a cooking apparatus to read a barcode of food and cook it without using a barcode reader separately. .

[0005]

According to a first aspect of the present invention, in a heating and cooking device for heating food stored in a heating chamber by a heating means, the heating cooking device is provided in the heating chamber and attached to the food. The reading means for reading the bar code and the heating control means for performing the heating operation set in the heating means based on the read data by the reading means are provided.

According to the above construction, the barcode is read by placing the food in the heating chamber, and the heating operation corresponding to the food is performed based on the read content.

By providing the reading means with a protecting means such as a shirt, the reading means is prevented from being contaminated, and in particular, the protecting means is opened only when the reading means reads it. The opening operation of the means can be omitted (the invention according to claim 2).

The reading means includes a ceiling portion, a bottom portion, and
When installed in the front position, etc., the barcode of the food in the heating position is read when installed in the ceiling or bottom, and when installed in the front position, the door is opened and the food is installed in the heating position in the heating chamber. The bar code can be read before the operation (the invention according to claims 3 and 4).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic configuration diagram of a microwave oven as a heating and cooking device of the present invention.

A heating chamber 1 is provided with a door 2 on the front surface thereof, and a transparent turntable 4 rotated by a motor A3 is provided in the lower portion of the heating chamber 1. Food 5 is placed on the turntable 4. Reference numeral 6 is a magnetron as a heating means, and 8 is a waveguide for guiding the high frequency wave from the magnetron 6 into the heating chamber 1.

Reference numeral 10 denotes a camera as a bar code reading means, which is provided so as to face downward in a recess 14 formed in the ceiling of the heating chamber 1. A shutter 12 as a protection means for the camera 10 is provided on the opening surface of the recess 14 and is opened and closed by a motor B13. Reference numeral 11 denotes an illuminating lamp as an illuminating means for illuminating the bar code portion of the food 5, which is attached to the back of the heating chamber 1.

FIG. 2 is a block diagram showing the structure of the microwave oven. Reference numeral 15 denotes a control section as a heating control means composed of a microcomputer, which includes the motor A described above.
3, Magnetron 6, camera 10, illumination lamp 11,
In addition to the motor B13, a memory 17 for storing a heating and cooking operation program and the like, an operation unit 18 for operation input, and a display unit 19 as a display unit for displaying various contents are connected. Then, the microcomputer 15 inputs each of the motor A3, the magnetron 6, the illumination lamp 11, and the motor B13 in accordance with the operation program stored in the memory 17 based on the input of the read content from the camera 10 and the operation content from the operation unit 18. Is designed to operate.

The operation will be described below with reference to the flowchart of FIG. First, the food 5 is placed on a predetermined position on the turntable 4 in the heating chamber 1. In this state, the shutter 12 is closed and the illumination lamp 11 is not turned on. Then, by closing the door 2 and performing a start input with the operation unit 18, the control unit 15 drives the motor 13 to open the shutter 12, and the illumination lamp 11 is turned on. As a result, the barcode portion of the food 5 is photographed, that is, read by the camera 10 (steps 1, 2, 3, 4).

When the read contents are given to the control unit 15, the memory 17 corresponding to the read contents is provided.
The name of the food stored in, for example, "Yakinik Bento" when used at a convenience store
Display at step 9 (step 5). As a result, the operator confirms the display contents, and if there is a reading error, the operator inputs an operation to stop the operation on the operation unit 18.
When the input is made, the operation ends (step 6). When there is no reading error and there is no operation input, the shutter 12 is closed, the illumination lamp 11 is turned off, and the motor A3 and the magnetron 6 are operated for the time corresponding to the food 5 to perform cooking and operation. Ends (steps 7, 8 and 9).

As described above, by placing the food 5 at a predetermined position in the heating chamber 1 and performing start input, the food 5
Cooking is performed in the cooking time corresponding to.

In particular, since the camera 10 is covered by the shutter 12 except during reading, the camera 10 is not contaminated by steam or the like during cooking so that reading can always be performed accurately. Further, since the barcode of the food 5 is illuminated by the illumination lamp 11 at the time of reading, the reading can be surely performed also by this.

Further, even if there is a reading error, the display unit 19 discriminates it so that erroneous cooking can be avoided.

The camera 10 as a reading means
May be provided at the bottom of the heating chamber 1 as shown in FIG. 4, or may be provided at the front side of the ceiling which is the front position in the heating chamber 1 as shown in FIG. If provided on the bottom,
Since the barcode can always be reliably read from a fixed close position, it is effective when the food 5 having various heights is cooked. In addition, when it is provided in the front position, the food 10 is put on the camera 10 when it is put in the heating chamber 1.
The reading can be surely performed by making the two face to face each other while holding them.

The opening and closing of the shutter 12 may be performed by using the opening and closing signal of the door 2.

[0020]

According to the present invention, the heating and cooking by reading the bar code can be easily performed only by placing the food in the heating chamber and starting the cooking.
