Description
Technical field
The present invention relates to micro-wave oven, particularly relate to a kind of micro-wave oven with energy-saving heat preserving function.
Background technology
Existing micro-wave oven is provided with the culinary art chamber that cooking food uses and places the electric control chamber of the microwave that generates being supplied with the electronic unit of described culinary art chamber in it.Described culinary art chamber is to be used for the put in space of heating of food to be heated, and electric control chamber is to place the space of the microwave that generates being supplied with the electronic unit of described heating clamber.
As shown in Figure 1, be provided with the magnetron 12 that generates microwave in the electric control chamber 4 of existing micro-wave oven, be arranged on the below of magnetron 12, to the high-tension transformer 14 of magnetron 12 pressurization, and the fan (not shown) that described magnetron 12 and high-tension transformer 14 are dispelled the heat, described magnetron 12 and high-tension transformer 14 are positioned at the place ahead of fan.
The power of blowing of fan makes that the outer air of stove is introduced in the housing forcibly by a plurality of air admission hole (not shown)s on the housing rear wall.The air of introducing circulates around magnetron 12 and high-tension transformer 14, thereby makes it cooling.
Air has passed through after the magnetron 12 that to be introduced into culinary art by air guide pipeline 11 indoor.In this case, air be flow through on the sidewall that is formed on the culinary art chamber air guide hole (not shown) and enter the culinary art chamber.Indoor in culinary art, be full of the smell and/or the steam of food in the air, subsequently through a plurality of steam vent (not shown)s on the culinary art chamber and discharge, enter in the air.Described steam vent is arranged on the opposite side of culinary art chamber.On the other hand, the air of the high-tension transformer 14 of flowing through then discharges from electric control chamber 4 through a plurality of bottoms venthole (not shown) downwards, and and then flows forward.Described venthole is arranged on the position of housing bottom, high-tension transformer 14 fronts.
When running of microwave oven, magnetron 12 and high-tension transformer 14 produce high heat, when these parts reach a high temperature, and described fan running, thus magnetron 12 and high-tension transformer 14 are cooled off.
Because micro-wave oven does not in the past have heat insulation function, so, when edible, also need to heat once more, the mouthfeel of food is descended if will not cool off with the food after microwave oven cooking/heating is edible immediately, nutritional labeling also can partly run off.Existing for this reason micro-wave oven has increased heat insulation function again, and the heat that produces by micro-wave oven itself is kept the temperature in the furnace chamber, thereby reaches the purpose that makes the food insulation.
But the micro-wave oven that is incubated by this way can consume much electricity, thereby has increased use cost.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide the micro-wave oven that a kind of heat that utilizes high-tension transformer (HVT) to produce reaches the insulation purpose.
The objective of the invention is to be achieved through the following technical solutions:
A kind of micro-wave oven comprises the magnetron that is arranged in the electric control chamber, is used to generate microwave; Be arranged on the below of magnetron, to the high-tension transformer of magnetron pressurization, and the fan that is arranged on the rear side of magnetron and high-tension transformer, magnetron and high-tension transformer are dispelled the heat, on the air supply direction of fan, be provided with wind deflector between door for microwave oven and the high-tension transformer, described wind deflector and high-tension transformer are pressed certain angle and are formed, be formed with a plurality of air-guiding holes on the furnace chamber wall between high-tension transformer and the door for microwave oven, the hot blast of blowing over high-tension transformer that is guided by wind deflector enters in the furnace chamber by air-guiding hole.
As an improvement of the present invention, described wind deflector has the cross section to the outside arc that protrudes of body of heater.
Improve as of the present invention another, described wind deflector also comprises a top panel integrally formed, that be used for closure tip.
Micro-wave oven of the present invention, the heat of HVT generation is blowed to the front portion of electric control chamber by fan, and under the guiding of wind deflector, be blown in the furnace chamber of micro-wave oven by air-guiding hole, in furnace chamber, form the hot blast of convection current, thereby can be incubated the food in the furnace chamber for a long time, and saved electric energy, reduced use cost.
Description of drawings
Fig. 1 is the structural representation of the electric control chamber of existing micro-wave oven;
Fig. 2 is the structural representation of the electric control chamber of micro-wave oven of the present invention.
The specific embodiment
Describe below in conjunction with the concrete structure of accompanying drawing micro-wave oven of the present invention.
As shown in Figure 2, micro-wave oven of the present invention comprises: be arranged in the electric control chamber 20, be used to generate the magnetron 22 of microwave; Be arranged on the below of magnetron 22, to the high-tension transformer (HVT) 24 of magnetron 22 pressurization, and the fan (not shown) that is arranged on the rear side of magnetron 22 and high-tension transformer 24, magnetron 22 and high-tension transformer 24 are dispelled the heat.
The power of blowing of fan makes that the outer air of stove is introduced in the housing forcibly by a plurality of air admission holes 26 on the housing rear wall.The air of introducing circulates around magnetron 22 and high-tension transformer 24, thereby makes it cooling.
Air is introduced in the cooking cavity (hereinafter to be referred as furnace chamber) by air guide pipeline 21 after having passed through magnetron 12.In this case, air be flow through on the sidewall that is formed on furnace chamber air guide hole (not shown) and enter furnace chamber.In furnace chamber, be full of the smell and/or the steam of food in the air, discharge through a plurality of steam vent (not shown)s on the furnace chamber subsequently, enter in the air.Described steam vent is arranged on the opposite side of furnace chamber.
In addition, in order to make full use of the heat that high-tension transformer 24 is produced, on the furnace chamber wall between high-tension transformer 24 and the door for microwave oven, be formed with a plurality of air-guiding hole (not shown)s, on the air supply direction of fan, be provided with wind deflector 25 between door for microwave oven and the high-tension transformer 24.Described wind deflector 25 press certain angle with high-tension transformer 24 and is formed, that is: wind deflector 25 is formed on the diagonal in the place ahead to the furnace chamber, the place ahead, the outside (direction the figure) from high-tension transformer 24 substantially.The hot blast of blowing over high-tension transformer by the wind deflector guiding enters in the furnace chamber by air-guiding hole.
Though the wind deflector 25 shown in the figure is a rectangle, but, can import more swimmingly in the furnace chamber of micro-wave oven in order to make fan blow over high-tension transformer 24 formed hot blasts, preferably, the horizontal section of described wind deflector 25 is to the outside arc that protrudes of body of heater.
In addition, the hot blast that is blowed in order more effectively to collect fan can also be provided with the top panel (not shown) at an integrally formed top that is used for confined bed aerofoil 25 for wind deflector 25, makes the below of top panel next-door neighbour PCB 21.
Like this, after micro-wave oven quits work, by fan blow through the hot blast that forms behind the HVT under the guiding of wind deflector, a plurality of perforates that form on the body of heater wall enter in the furnace chamber, thereby can the food in the furnace chamber be incubated.The operation of fan can be controlled by PCB, correspondingly, special insulation shelves can be set on control panel, the function that the heat that the control by PCB realizes utilizing HVT to produce is incubated.
