Micro-wave oven on the market has varied now.Micro-wave oven normally is placed on the desktop and uses.But in the micro-wave oven that occurs, the ventilating hood-type microwave oven that possesses fume exhausting function is arranged recently.This micro-wave oven is positioned at the top of culinary art facility, such as the top of gas furnace etc., in order to discharge oil smoke and the heat that they produce.
As shown in Figure 1, the micro-wave oven of existing a kind of bell-type that ventilates generally comprises: be used for heat food heating clamber 10 and be arranged on the electric control chamber 20 of the side of heating clamber 10.Be provided with electric component in the described electric control chamber 20, as be used for producing the magnetron 22 of microwave and to the step-up transformer 24 of magnetron 22 input power supply signals etc. to heating clamber 10 launched microwaves.
In order to make described magnetron 22 and step-up transformer 24 heat radiations, be provided with fan 26 on the top of electric control chamber 20, can flow through magnetron 22 and step-up transformer 24 of the air stream that fan 26 produces makes its heat radiation, wherein portion of air stream flows into heating clamber 10 by the air inlet 10a on heating clamber 10 sidewalls, and the steam that heating clamber 10 produces in heating process is crossed the exhaust outlet 10b that is arranged in heating clamber 10 left side wall tops and discharged from the heating clamber of micro-wave oven along with this burst air communication.
The rear on described heating clamber 10 tops is provided with exhaust motor assembly 14, and the place ahead of described exhaust motor assembly 14 is provided with air duct 12.The bottom of micro-wave oven is provided with baking oven, and the flue gas that baking oven produces outwards emits through air duct 12 under the driving of exhaust motor assembly 14.
During micro-wave oven work, produce steam in the heated food,, can control the heating process of food by measuring the humidity of heating room air.The humidity sensor Sa (Sensor) that is used for measuring heating clamber inner air humidity is arranged on the corresponding position, top with described heating clamber exhaust outlet 10b, for example be arranged on the corresponding air duct 12 in the top of described exhaust outlet 10b in.
But the air duct 12 in the existing ventilating hood-type microwave oven only has the effect of supporting described humidity sensor (Sensor), and function singleness can't play facilitation to the air humidity measurement function of humidity sensor.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of ventilating hood-type microwave oven, its air duct that has also has the guide functions of air-flow, the steam that can guide heating chamber for microwave oven to produce in heating process is discharged from humidity sensor, bring into play the air humidity mensuration effect of humidity sensor better, make it possible to more effectively the heating process of food be controlled.
For this reason, the invention provides a kind of ventilating hood-type microwave oven, include body of heater 1, has heating clamber 10 in the described body of heater 1, the top of described heating clamber 10 is provided with an air duct 2, described air duct 2 is provided with a temperature sensor 3, the top of described heating clamber 10 is provided with exhaust outlet, have an air introducing port 21 and an air export mouth 22 on the described air duct 2, the corresponding setting of exhaust outlet on described air introducing port 21 and described heating clamber 10 tops, described air export mouth 22 and described temperature sensor 3 corresponding settings.
Preferably, described temperature sensor 3 is positioned at the right side of described air duct 2.
Preferably, described air introducing port 21 and air export mouth 22 lay respectively at the two ends, the left and right sides of described air duct 2.
By above technical scheme provided by the invention as seen, the air duct that has in a kind of ventilating hood-type microwave oven provided by the invention not only has the effect of supporting humidity sensor, the steam that can also guide heating chamber for microwave oven to produce in heating process is discharged from humidity sensor, bring into play the air humidity mensuration effect of humidity sensor better, make it possible to more effectively the heating process of food be controlled.
