Description

The micro-wave oven of tape font code control system

Technical field

The utility model relates to a kind of micro-wave oven, relates in particular to a kind of micro-wave oven of tape font code control system.

Background technology

The main effect of micro-wave oven is the mode of heating heat food of utilizing microwave, barbecue or hot blast and making up mutually.At present, general conventional microwave oven realizes that the control mode of food heating mainly is digital-code type control mode or mechanical type control mode.For digital-code type control mode micro-wave oven or mechanical type control mode micro-wave oven,, all need the operator that the heating recipe of the heating properties of micro-wave oven, micro-wave oven, the physical characteristic that is heated food are had sufficient understanding and understanding no matter wherein any; Otherwise food is difficult to the thermal effect that adds that reaches desirable.China Patent No. 00251071.5 discloses the full-automatic micro-wave oven of a kind of read code operated in addition, mainly be by being positioned at the wanding device of micro-wave oven inner and upper position, read the bar code data on the food after the footpath row judge that a heating second number, firepower size are with direct heating; When if the wanding device is failed normal operation, then food can be taken out, row reads the bar code data with the wanding window scanning at exterior panel place again, food is placed the usefulness of micro-wave oven for heating again; The automatic detecting temperature device that is positioned at the inner lower position of micro-wave oven will be surveyed the temperature of food automatically, can finish heating after reaching setting value.Its major defect: the one, micro-wave oven internal structure complexity is unfavorable for heating using microwave, and very easily pollutes, damages with the inner wanding device of the carrying out of heating process; The 2nd, on the structure and read on the mode, the wanding device is difficult to accurately read the bar code data on the food, very easily causes the micro-wave oven maloperation; The 3rd, the temperature that automatic detecting temperature device is surveyed is the temperature that foodstuff surface reaches at first, but not the temperature that whole food had.

Summary of the invention

In order to overcome existing micro-wave oven not enough all shortcoming that is caused on control mode, the utility model provides a kind of micro-wave oven with new control system.This control system makes micro-wave oven become safe, easy, efficient to the heating of food, has enlarged the use of microwave ovens crowd, also makes the heating function of micro-wave oven be not fully exerted.

The technical scheme that its technical problem that solves the utility model adopts is: be heated the bar code that adds thermal information on the food with band, this bar code is the best eating effect according to the physical characteristic of food and food, set by the professional, do not need operator oneself to set.Be provided with bar code at the exterior panel place of micro-wave oven and read window, the window inboard is provided with apparatus for reading of bar code, is provided with the heating control system of information processor and micro-wave oven in the furnace chamber of the micro-wave oven outside and administrative area, body of heater shell inboard; The output of apparatus for reading of bar code is connected through the electrical signal transmission line road with the input of information processor, the output of information processor is connected through the electrical signal transmission line road with the heating control system of micro-wave oven.When food need heat, at this moment only need place bar code to read window the place ahead, allow apparatus for reading of bar code read bar code and add thermal information and get final product with the bar code on the food or together with food.Then food is placed in the micro-wave oven furnace chamber, close upper furnace door, micro-wave oven will realize automatically that whole heating process is until stopping heating.The realization of whole heating process is to read bar code by apparatus for reading of bar code to add thermal information, again bar code is added thermal information and is transferred to information processor, and the heating control information after information processor will be handled again is transferred to the heating control system of micro-wave oven; When door of microwave oven is closed, the micro-wave oven heating control system will automatically perform received heating control information, and the performed heating control information of deletion automatically when heating process finishes.After if apparatus for reading of bar code reads bar code and adds thermal information, in the time of setting, do not carry out heating operation, then the micro-wave oven heating control system will be deleted received heating control information automatically.In addition, if apparatus for reading of bar code is when reading different bar codes continuously and add thermal information, the bar code that so last time read adds thermal information and will be added thermal information by the bar code that time read the back and replace, micro-wave oven will be carried out the bar code that reads for the last time and add thermal information, can guarantee that like this micro-wave oven maloperation can not take place.Also be provided with an information display window and several function keys at the exterior panel place of micro-wave oven, information display window is with each operating procedure of synchronous microwave oven; Function key comprises function keys such as key heat time heating time, heating mode key, heating firepower key, heating schedule key; These function keys are digital control mode or the mechanical control methods that are used for micro-wave oven.If food does not have subsidiary or has lost the bar code that band adds thermal information, at this moment just be heated every thermal control parameter that adds of food with the function key assignments, be used for controlling micro-wave oven and finish heating food.

The beneficial effects of the utility model are, on present known micro-wave oven, set up a kind of brand-new bar code control system, this system not only can not cause damage to every function of micro-wave oven, and makes micro-wave oven become safe, easy, efficient to the heating process of food.Anyone GPRS bar code read method, just can control micro-wave oven easily, and then finish heating, and can obtain the best eating effect of food various foods.
