Description
Technical field
The present invention relates to micro-wave oven, especially utilize baffle plate that the electric control chamber inboard is divided into cooling end and exhaust portion, outside air is drawn into the cooling structure of the microwave oven electric control chamber of discharging by exhaust portion behind the cooling electric control chamber inside in the cooling end.
Background technology
Usually micro-wave oven is to utilize the electric current of supply to produce microwave, and the device that microwave irradiation is heated to the heating object, and can heat the inside and the outer surface of heating object simultaneously, is used to cook various foods.
As shown in Figure 1, the micro-wave oven of prior art adopts rectangular structure haply, and the top and left and right sides face of micro-wave oven 1 forms shell 10, and shell 10 combines with the chassis 12 that constitutes micro-wave oven 1 bottom outward appearance.
Be provided with furnace chamber assembly 20 in shell 10 inside.Furnace chamber assembly 20 comprises the heating clamber 30 that heating space is provided and has been equipped with the electric control chamber 40 that starts the required electric component of micro-wave oven, and furnace chamber assembly 20 is made of the furnace chamber main body 22 of the box-like of front and back opening and the front panel 24 that forms respectively on the front-end and back-end of furnace chamber assembly 20 and rear board 26.
The open at its front of heating clamber 30, and optionally open and close by fire door 14.Fire door 14 is arranged on the front of front panel 24, can rotate, and can optionally open and close heating clamber 30.
On the bottom surface of heating clamber 30 inside, be provided with rotating disk 32.Rotating disk 32 is used for placing heating object in the above, and it adopts disc-shaped structure, and drives rotation by the rotary tray motor that is arranged on its downside (not expression among the figure), and microwave and heat can be fed on the heating object uniformly.
At the rear side of electric control chamber 40, promptly be provided with suction hole 26 ' on the side of plate 26 in the back.Suction hole 26 ' is the passage that the suction of generation sucks air when utilizing Air Blast fan 46 rotations from the outside, runs through rear board 26 and is provided with several suction holes 26 '.
Right flank at heating clamber 30 has formed ostium 40 '.Ostium 40 ' is the passage that makes air inflow heating clamber 30 inboards of cooling magnetron 42 under the effect of Air Blast fan 46, runs through heating clamber 30 right side walls and is provided with several ostiums 40 '.
In ostium 40 ' arranged outside air duct 49, the air that magnetron 42 has been cooled off in guiding after the electric control chamber 40 rears air-supplies enters ostium 40 ' glibly, air duct 49 back openings and two sides sealing.
Be provided with steam vent 30 ' on one side of heating clamber 30 left surfaces corresponding with electric control chamber 40.Steam vent 30 ' is that the air that flows into heating clamber 30 inside is discharged to outside passage, and the left side wall that runs through heating clamber 30 is provided with several steam vents 30 '.
As above the air draught of the course of work of the existing micro-wave oven of Gou Chenging and inside is as follows:
As shown in Figure 2, after micro-wave oven 1 was connected power initiation, high-tension transformer 44 and magnetron 42 started, and microwave are provided for heating clamber 30 inside.At this moment, high-tension transformer 44 and magnetron 42 can heat releases when work.Meanwhile, Air Blast fan 46 starts, and produces suction, utilizes this suction to suck air from the outside by suction hole 26 ', and air is delivered to electric control chamber 40 inboard the place aheads.48 is the Air Blast fan location structure.
The air that Air Blast fan 46 is sent is these electric components of air cooling through electric components such as magnetron 42 and high-tension transformers 44 time, and flow into heating clamber inside by ostium 40 ' under the guiding of air duct 49.
The air steam vent 30 ' by heating clamber 30 left surfaces under the effect of the blast of ostium 40 ' side that flows into heating clamber 30 inside is discharged.
But there is following problem in prior art as above: discharge inner air by steam vent 30 ', air is discharged not smooth, and when producing water vapour in cooking process, water vapour can't be discharged smoothly.And, to discharge across heating clamber 30 and by steam vent 30 ' by ostium 40 ' leaked-in air, the inflow air capacity that therefore residues in heating clamber 30 inboards increases, and has seriously hindered the discharge of water vapour.So, owing to the too much water vapour of heating clamber 30 inside, had a strong impact on the identity of system, when the user cooks, judge that cooking status becomes very difficult, uses very inconvenient.And, after finishing culinary art, because water vapour remains in inside, the dewfall phenomenon takes place, the heating clamber internal environment becomes untidy, causes that easily the user is discontented.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of baffle plate that utilizes that the electric control chamber inboard is divided into cooling end and exhaust portion, and outside air is drawn into the cooling structure of the microwave oven electric control chamber of discharging by exhaust portion behind the cooling electric control chamber inside in the cooling end.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of cooling structure of microwave oven electric control chamber comprises: the heating clamber of depositing heating object and cooking; To be arranged on a side of heating clamber, to be equipped with the electric control chamber of some electric components in order cooking; Be arranged on a side of electric control chamber, forcing ambient air delivered to the Air Blast fan of electric control chamber inboard; In the electric control chamber inboard, being provided with the electric control chamber internal separation is the cooling end of cooling electric parts and the baffle plate that the cooled air of guiding is discharged to outside exhaust portion, utilize Air Blast fan to make and force to be drawn into the outside air inflow heating clamber inside of cooling end, and make the air that flows into heating clamber inside be discharged to the outside through exhaust portion.
Described Air Blast fan and electric component are arranged on the cooling end.
One side end of described baffle plate contacts with the madial wall of electric control chamber, and end side contacts with the heating clamber outer side surface.
One side being provided with of described cooling end run through the suction hole to cooling end guiding extraneous air of electric control chamber one side wall surface.
On a side of cooling end, formed the ostium that air that the guiding that runs through heating clamber one side wall surface enters by suction hole flows into to heating clamber.
Side in exhaust portion has formed the tap hole of the air of the guiding heating clamber inside of running through heating clamber one side wall surface to the exhaust portion outflow.
The guiding that has formed a side wall surface that runs through electric control chamber on a side of exhaust portion is discharged to outside steam vent by tap hole from the air that heating clamber flows out to exhaust portion.
Described suction hole and steam vent are arranged on adjacent to one another on the position, and are as the criterion with baffle plate, are arranged on both sides.
The invention has the beneficial effects as follows: the steam vent that will discharge the electric control chamber inner air is arranged on the position of closing on suction hole, exhaust velocity has been subjected to the influence of the air draught that is forced into by suction hole, accelerate to discharge the speed of the air of heating clamber inside, promoted whole air circulation.Owing to promoted the discharge of the air of heating clamber inside, can discharge the water vapour of heating clamber inside glibly, prevent the phenomenon of and fire door inboard dewfall inner at heating clamber.And when cooking, the user can confirm the cooking status of heating object easily, has not only improved user's ease of use, but also has prevented owing to the heating clamber internal condensation, and the inner blowzy phenomenon of heating clamber reduces the discontented of user.
