Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention has a bar code input device for notifying a reading error and has a means for selecting two input methods, one for performing various operations of an electric water heater and the other for operating with an operation switch or the like. It relates to an electric water heater for business.

[0002]

[Prior Art]

 A conventional electric water heater has a container that holds water, a heating element that heats the water in the container, operation switches for various operation inputs, etc., detects boiling and controls the electricity to the heating element to keep it warm. It had a control device to maintain the temperature, and input operation such as re-boiling, keeping temperature setting, timer setting, etc. was performed only by operating switches. ◇ (For example, Japanese Utility Model Laid-Open No. 1-178831) In addition, there is no electric water heater that uses a bar code, but recently, it is a heating cooker such as an electronic range, which has a bar code reader and is on a cooking guidebook. Some barcodes are read and cooked. (For example, Japanese Utility Model Laid-Open No. 58-30104) In addition, there is a bar code reader with a bar code display for cooking on the surface of the main body and a storage part for the bar code reader. (For example, Japanese Utility Model Laid-Open No. 61-141614) Further, there is a method in which heating information is input by reading a bar code, an erroneous reading inspection is performed for each bar code and the entire bar code, and if the reading is correct, there is a notification. (For example, Japanese Patent Laid-Open No. 62-175526)

[0003]

[Problems to be solved by the device]

 In the conventional general electric water heater, various settings and operations were performed by operating the keys on the operation panel mounted on the front or upper part of the main body, and the operation switches were used to input to the control device for operation.

According to this method, the setting of the timer or the like is set such that the feed is set every hour from a certain time to the desired time by forward feed or reverse feed. Therefore, when the feed is set, the set time is erroneously exceeded. Then, I had to make another round to set again, and if I made a mistake, it took time to set the timer.

[0007] Although a cooker having a bar code is easy to input using a bar code, it is not as easy to carry as a water heater, and further, if the bar code is printed on a document such as an instruction manual. , The bar code cannot be visually confirmed, and elderly people with poor eyesight may not be able to distinguish even if there is a description of the mode, etc., and the main body with a bar code reader that is difficult to carry each time you move the main body together with the documents It had the drawback that it had to be carried around.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and a bar code input device for notifying an error when a reading error occurs in a control device is connected to an input terminal that can be attached / detached, and re-boiling, heat-retention temperature setting, The barcode input device can be attached / detached by selecting multiple operating methods, such as operating the bar code input device for inputting operations such as timer settings, or operating the switch on the operation panel.

[0007]

[Action]

 With the above configuration, various input operations can be performed easily, such as setting the timer by directly reading the desired time such as 1 hour or 2 hours from the bar code printed on the main unit with the bar code input device. At the same time, it has an effect of notifying an error immediately when a reading error occurs, and also has an effect of allowing various inputs from the operation switches as in the conventional case.
