Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to the structure of a wireless barcode reader.

<Prior Art> Modern cooking appliances, especially microwave ovens, have become multifunctional with the spread of microcomputers and sensors, and many keys are arranged on the operation panel. For example, various menu keys for automatic (automatic) heating, microwave high/medium/low keys for manual heating, grill, convection, etc., and the wife heating sequence created by these key inputs are memorized. There is a memory key. It is very troublesome for the user to operate these keys and make settings (heating time and temperature) according to each menu, and erroneous settings are likely to occur, and the usability is poor.

Therefore, information such as heating time, heating temperature, heating output, sensor detection level, etc. for each heating stage is printed as a barcode on the cooking book that comes with the microwave oven, and the user can read the barcode print with a barcode reader. For example, a convenient microwave oven has been proposed that allows settings to be made according to the cooking menu.

However, if the barcode reader and the microwave oven body are wired, the barcode reader has the disadvantage of poor usability, so wirelessization is being considered, but various considerations have been raised in the wirelessization.

<Purpose> Among the above-mentioned considerations, the present invention addresses the issue of installing a memory operating means in a wireless barcode reader that stores a cooking sequence based on a barcode signal transmitted by the wireless barcode reader in the built-in memory of the cooking device. For the purpose of setting up.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 is a schematic explanatory diagram of a microwave oven that employs the wireless barcode reader of the present invention, Figure 2 is an electrical circuit diagram of the wireless barcode reader, and Figure 3 is a schematic diagram of a microwave oven that uses the wireless barcode reader of the present invention.
The figure is an electrical circuit diagram of the microwave oven main unit related to the wireless barcode reader, Figure 4 is a front view of the operation panel of the microwave oven main unit related to the wireless barcode reader, and Figure 5 a, b, and c are the main They are a front view, a right side view, and a bottom view of the wireless barcode reader of the invention.

The wireless barcode reader 1 of the present invention reads the barcode 2a printed on the cooking book 2,
It has the function of wirelessly transmitting the read information to the microwave oven main body 3.

The wireless barcode reader 1 includes a reading section 3 that illuminates the barcode 2a with light from a light emitting diode 3a and receives the reflected light with a light receiving diode 3b to read the barcode 2a, and a red section that transmits the read barcode information by infrared rays. It is provided with external light emitting diodes 4, a control circuit section 5 for controlling them, a secondary battery 6 for power supply, and a charging jack 7 for charging the secondary battery 6. The reason why the secondary battery 6 is used as the power source for the wireless barcode reader 1 is that a large current is required to make the infrared light emitting diode 4 emit light, and microwave barcodes have a large amount of information, so a large current is required. It has to be run for a long time and the battery is consumed rapidly. Therefore, the purpose is to reduce the burden on the user as much as possible.

As shown in FIG. 4, the operation panel 8 of the microwave oven main body 3 has a reader storage section 9 that stores the wireless barcode reader 1 and a receiving section 10 that receives the barcode signal transmitted from the reader 1. It is provided near the pipe 11. A charging plug 12 is disposed in the innermost part of the reader storage section 9 and is connected to the charging jack 7 of the reader 1 when the reader 1 is inserted and stored.The charging plug 12 is connected to the charging circuit 13. It is connected.

Further, the receiving section 10 includes a photodiode 10a that receives infrared rays from the reader 1 and a light receiving circuit 10b.
and outputs the received barcode signal to the control circuit 14. The control circuit 14 controls the microcomputer wave heating device 15, the heater 16, etc. based on a heating program input from the receiving section 10.

The reading section 3 and the charging jack 7 are arranged on one side of the reader 1 as shown in FIG.
protrudes slightly from the charging jack 7. or,
An infrared light emitting diode 4 is disposed on the other side and covered with a filter 17. Therefore, when the reader 1 is inserted and stored in the reader storage section 9, only the filter 17 is visible. The direction of orientation of the infrared light emitting diode 4 is perpendicular to the direction of orientation of the reading section 3. The reason is that when reading barcode 2a of cookbook 2,
Place cookbook 2 on a desk or in your hand, and place reader 1 with the barcode printed side parallel to the ground.
Generally, the microwave oven main unit 3 is placed vertically to the ground, so the transmitter 10 can be efficiently transmitted using the infrared light emitting diode 4, which has an output of 40% less and has a transmission direction of approximately ±30°. This is because in order to transmit, it is necessary to transmit substantially perpendicular to the reader 1, that is, substantially perpendicular to the directional direction of the reading unit 3.

A barcode reading key 18 is provided at the bottom of the reader 1, and a stop/cancel key 19, a heating key 20, and a heating key 20 are provided at the top of the reader 1 at a height of 3 cm or more from the reading section 3. A memory key 21 is provided to cause a control circuit 14 having a memory function in the microwave oven main body 3 to memorize a cooking sequence based on a barcode signal. Two memory keys 21 are provided, and two types of cooking sequences out of several commonly used cooking sequences are stored in the control circuit 14 in correspondence with the two memory keys 21, respectively.

The reason why the stop/cancel key 19, the heating key 20, and the memory keys 21, 21 are provided at the top of the reader 1 at a height of 3 cm or more is that the reader 1 can be held in the hand and the barcode 2a of the cookbook 2 can be read. This is to prevent unexpected erroneous operations caused by unconsciously touching the stop/cancel key 19, the heating key 20, or the memory keys 21, 21 when tracing. The stop/cancel key 19 and the heating key 20 are essential functions for a microwave oven, and are essential for using the reader 1 as a remote control.

Next, the operation of the reader 1 will be explained. Pull out the wireless barcode reader 1 from the microwave oven body 3, hold it in your hand, press the barcode reading key 18, and trace the barcode 2a on the cooking book 2 to read it. When the heating key 20 is pressed, the microwave oven controls the microwave heating device 15, heater 16, etc. to start heating. If you want to stop heating midway through, press the stop/cancel key 19 and the control circuit will start the microwave heating device 15, heater 16, etc.
Turn it off.

Also, press the barcode reading key 18 to trace and read the barcode 2a of the cooking book 2 corresponding to one type of cooking that is commonly used, and then press the memory key 21 to read the barcode 2a and create a recipe. The cooked cooking sequence can be stored in the control circuit 14 in the microwave main body 3, and similarly to the memory key 21, the cooking sequence can be stored in the memory key 21 to correspond to one other commonly used type of cooking. The cooking sequence to be prepared is stored in the control circuit 14.

Then, by pressing the memory key 21 again, one of the cooking sequences stored in the control circuit 14 can be called up.
By pressing No. 1 again, the other cooking sequence stored in the control circuit 14 can be called up.

In this way, the control circuit 14 includes the memory key 2.
Two types of commonly used cooking sequences corresponding to or of 1 can be stored in memory, and when cooking, cooking can be easily performed by simply operating or of the memory key 21 corresponding to the cooking. can.

Therefore, the user can easily and reliably make input settings corresponding to the menu simply by tracing the barcode on Cookbook 2, and can also start and stop heating, cancel input settings, and manipulate the cooking sequence memory. This can be done without having to go to the front of the microwave oven main body 3, which is very convenient and easy to use.

<Effects> The present invention is a wireless barcode reader that transmits the barcode signal read by the reading unit from the transmission unit to the cooking device itself, and has a remote control operation means that is essential for the cooking device, such as starting and stopping heating. By using a wireless barcode reader that is equipped with a memory operating means that stores the cooking sequence based on the transmitted barcode signal in the built-in memory of the cooker, the user can easily input settings from any location. It is very convenient and has high practical value because essential functions such as heating start and stop, as well as the memory function of the cooking sequence created by reading the barcode reader, can be operated by remote control.
