Abstract
The utility model relates to an IC card type microwave oven, which comprises a main body of a microwave oven, a panel, a display screen, various functional buttons and a CPU chip for central control. The utility model is characterized in that the panel is provided with an IC card reading device capable of being inserted with an IC card and an input signal key of an IC card. Besides, the IC card reading device and the input signal key of the IC card are connected with the CPU chip for central control through signal connecting lines. The three ports PTEO, PTE1 and PTDO of the CPU chip are respectively connected with the P2, the P4 and the P3 of the IC card reading device. The utility model has the characteristics that uses can write and read for a plurality of times, query or modification is convenient, and uses can conveniently and directly acquire new information from manufacturers.
Description
The utility model relates to a kind of IC-card formula micro-wave oven.
The existing accessible curing menu of micro-wave oven can only be the fixing several of minority, and its particular content is difficult to show to the user at micro-wave oven itself, what show is the symbol or the Chinese character of several fixedly meanings, and how to use, especially how using more easily according to various needs of users is more effective, obviously is people's demand.
The purpose of this utility model provide a kind of by the user need or hobby can be adjustable flexibly or the change menu, and can inquire about the IC-card formula micro-wave oven of menu content at any time.
The technical solution of the utility model is to utilize existing IC-card technology, and the micro-wave oven cpu chip is linked to each other with IC-card, makes its content that can read IC-card, is shown on the screen with a giant-screen dot lcd.Specifically establish an IC-card button at the fixed signal input port of the cpu chip that has micro-wave oven computer plate, and on the corresponding output port of working signal pulse input tie point configuration LCDs, read device and corresponding IC-card seat be set on main body panel and one IC-card is set at output port.
Its advantage is to utilize the rewritable of IC-card, variable menu data is deposited in the IC-card, the user can repeatedly be read and write, i.e. inquiry or change are convenient, manufacturer also can regularly send to user such as operating characteristic of micro-wave oven, makes it to obtain easily and intuitively fresh information.
Provide specific embodiment of the utility model below in conjunction with accompanying drawing.
Fig. 1, basic structure front view of the present utility model.
Fig. 2, the utility model medial side view.
Fig. 3, circuit theory diagrams of the present utility model.
As Fig. 1, as Fig. 2, the present invention includes micro-wave oven main body 1, panel 2, display screen 3, with various function buttons with as the central cpu chip of controlling 8, it is characterized in that it also is included in panel 2 and is provided with an IC-card that can insert IC-card 5 and reads device 6 and an IC-card input signal button 4, and link to each other with the cpu chip 8 of central authorities control by signal link 7.Above-mentioned cpu chip 8 is chosen model MC68, and three port PTEO, PTE1 wherein and PTDO read the CLK (P of device 6 respectively with IC-card
2), SDA (P
4) and PWR (P
7) link to each other, thereby formation PTEO-CLK is an input end of clock, and the clock signal of reading and writing IC card 5 is provided.PTE1-SDA is a data terminal, is serial port, utilizes its data to IC-card to read and write.PTDO-PWR is the Data Detection end, utilizes IC-card to read the switch P commonly used of device 6
3, P
4Confirm whether IC-card inserts.As Fig. 3, power vd D, VSS are the working power of IC-card seat, and wherein VSS is a zero level, VDD is+and the high level of 5V, meet P
8VDD through respectively through three protective resistance R
