Abstract

The utility model discloses a microwave oven capable of automatically identifying food. The microwave oven comprises an oven chamber, an oven door switch, function keys and a shell of the oven door, wherein a controller, a power transformer, a magnetron and a waveguide system are arranged in the shell; the magnetron generates microwave under the excitation of the power transformer and the microwave is transmitted to the oven chamber through the waveguide system; the function keys are connected with the input end of the controller; a mode selection switch is arranged on the shell; a spectrometer is arranged in the oven chamber; the output end of the spectrometer and the function keys are connected with the input end of the controller in parallel through the mode selection switch. According to the microwave oven capable of automatically identifying food, the spectrometer is used for analyzing the components of the food, the analyzed result is input to the controller and is compared with the data stored in the controller to identify the food type; the heating time is automatically selected without manual operation of the function keys, the usage is convenient, the food can be heated to a best state for eating and is tasty and healthy.

Description

A kind of micro-wave oven of automatic identification food

Technical field

The utility model relates to micro-wave oven field, is specifically related to a kind of micro-wave oven of automatic identification food.

Background technology

Micro-wave oven is to utilize food microwave energy absorbing and make the cooking apparatus of conducting self-heating in microwave field, the power transformer of micro-wave oven provides the voltage of about 4000 volts to magnetron, magnetron produces continuously microwave under the excitation of this voltage, again through fluctuating system, coupled in furnace chamber, microwave penetrates food with the frequency of oscillation of 2450MHZ, when microwave is during by food absorption, polar molecule in food is attracted with the speed quick oscillation of 2,400,000,000 5 thousand ten thousand times each second as water, fat, protein, sugar etc., and the macro manifestations of this vibration is exactly that food has been heated; Micro-wave oven with convenient, fast, more and more appear in daily life without the feature of oil smoke.

Current micro-wave oven is general or need to determine the heat time by the artificial kind of selecting food to be heated of function key; be subject to the impact of its housing area; the function key area of micro-wave oven is generally only provided with the function key that several scopes are comparatively wide in range; such as thawing, milk, cook, Steamed fish etc.; in the time that exceeding the food of these scopes, processing often there will be phenomenon not yet done or that overdo; not yet done food need to carry out post bake; and the food overdoing also may work the mischief to human body when mouthfeel is poor, inconvenient and dangerous.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of micro-wave oven of automatic identification food, can solve existing micro-wave oven need to be by the artificial kind of selecting food to be heated of function key, be subject to its housing area effect, available function key is less, causes inconvenient in the time that processing exceeds the food of function key scope and unsafe problem.

The utility model is achieved through the following technical solutions:

A kind of micro-wave oven of automatic identification food, comprise the housing that is provided with furnace chamber, stove door switch, function key, fire door, in described housing, be also provided with controller, power transformer, magnetron and Wave guide system, the microwave that described magnetron produces under power transformer excitation is sent into furnace chamber through Wave guide system, described function key is connected in controller input, on described housing, be also provided with mode selection switch, in described furnace chamber, be provided with spectral investigator, the output of described spectral investigator and function key are parallel to the input of controller by mode selection switch.

Described spectral investigator is arranged at furnace chamber top, and towards furnace chamber bottom.

Spectral investigator is a kind of checkout gear based on near-infrared spectrum technique, have easily and fast, not damaged, without features such as sample pretreatments.

The utility model advantage is compared with prior art:

Analyze the composition of food by spectral investigator, by after analysis result input control device with controller in the Data Comparison that stores judge food species, automatically select the heat time, without manual operation function key, easy to use and food can be heated to best edible state, delicious food is healthy again.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is electrical structure schematic diagram of the present utility model.

Detailed description of the invention

The micro-wave oven of a kind of automatic identification food as depicted in figs. 1 and 2, comprise and be provided with furnace chamber 2, stove door switch 3, function key 4, the housing 1 of fire door 5, in described housing 1, be also provided with controller, power transformer, magnetron and Wave guide system, the microwave that described magnetron produces under power transformer excitation is sent into furnace chamber 2 through Wave guide system, described function key 4 is connected in controller input, on described housing 1, be also provided with mode selection switch 6, described furnace chamber 2 tops are provided with the spectral investigator 7 towards furnace chamber 2 bottoms, the output of described spectral investigator 7 and function key 4 are parallel to the input of controller by mode selection switch 6.

When heat food, first open fire door 5 by stove door switch 3, after being put into furnace chamber 2, food container 8 closes fire door 5, mode selection switch 6 is given tacit consent to the input conducting of output and the controller of spectral investigator 7, food is identified automatically, in the time of spectral investigator 7 fault, be switched to manual mode by mode selection switch 6, carry out heating mode selection by function key 4.
