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, there are various menu keys for automatic heating, microwave high/medium/low, grill, convection keys, etc. for manual heating. It is very troublesome for the user to operate these keys and make settings (heating time and temperature) according to each menu, and it is easy to make erroneous operations and settings, 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 printout 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 itself are wired, there is a drawback that the barcode reader is not easy to use, so a wireless version is being considered, but various considerations have been raised in the wireless version. .

<Purpose> Among the various considerations mentioned above, the present invention provides a wireless barcode reader with a remote control unit for remote control of cooking functions such as starting and stopping cooking, which are essential functions of a cooker, and a wireless barcode reader. The purpose is to improve the operability of the reader.

<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 unit side diagrams. 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 10.
b, and outputs the received barcode signal to the control circuit 14. The control circuit 14 controls the microwave heating device 15, the heater 16, etc. based on a heating program input from the receiving section 10.

In the present invention, the reading section 3 and the charging jack 7 are arranged on one side of the reader 1 as shown in FIG. It stands out a little more. Further, an infrared light emitting diode 4 is arranged 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 orientation direction of the infrared light emitting diode 4 is determined by the reading section 3.
The direction of orientation is perpendicular to each other. The reason for this is that when reading the barcode 2a of the cookbook 2, it is best to place the cookbook 2 on a desk or in your hand, with the barcode printed surface parallel to the ground, and hold the reader 1 vertically. This is common, and the microwave oven body 3 is also placed perpendicular to the ground, so the output is 40
In order to efficiently transmit data to the receiver 10 using the infrared light emitting diode 4, which has a transmission direction of approximately ±30°, it is necessary to transmit substantially perpendicular to the reader 1, that is, substantially perpendicular to the direction of the reading section 3. It is.

A barcode reading key 18 is provided at the bottom of the reader 1, and a stop/cancel key 19 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. It is arranged.

The reason why the stop/cancel key 19 and the heating key 20 are provided on the top of the reader 1 and at a height of 3 cm or more is that when you hold the reader 1 in your hand and trace the barcode 2a on the cookbook 2, you can stop/cancel the food. This is to prevent unexpected erroneous operations caused by touching the heating key 19 or the heating key 20 unconsciously. This stop/
The 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.

Therefore, the user can easily and reliably make the input settings corresponding to the menu by simply tracing the barcode on the cookbook 2, and can also start or stop heating or cancel the input settings by touching the microwave main body 3.
It is very convenient and easy to use because it can be done without having to go to the front of the machine.

<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 unit that has essential functions for the cooking device such as starting and stopping heating. By using a wireless barcode reader equipped with a wireless barcode reader, users can input settings with ease from any location, and essential functions such as starting and stopping heating can be controlled with a remote control, making it very convenient and easy to use. It is of high value.
