Adopt the above embodiments, can obtain following effect.
At first, since be with the interior case 3 that constitutes heating clamber 4 top plate portions top board 3e, configuration above it thermal insulation board 23 and be located in protuberance 20 on the top board 3e of case 3 form the ventilation road 24 of front portion above the top board 3e of wind case 3 in air-guiding aisle 18 is guided into of the cooling fan 16 that will pass through magnetron 13, therefore different with the occasion that special-purpose air intake passage is set on the top plate portion of heating clamber 4, do not need to be provided with in addition special-purpose air intake passage, not only can corresponding minimizing part number, also can reduce cost.
In this occasion, because raised part 20 is arranged on the top board 3e (top plate portion of heating clamber 4) of interior case 3, and be also used as the reflecting plate of heater 19, therefore compare with the occasion that special-purpose protuberance is set for formation ventilation road 24, but simplified structure.
Again, owing to the rake 26 that is provided with in the front portion of thermal insulation board 23 to the front lower place, the wind that 24 process top plate portion air entries 21 are supplied with in heating clamber 4 from the ventilation road are flowed along this rake 26, therefore be convenient to this wind and flow, can prevent effectively that door 7 from tying mist because of the steam that gratin produces along the inner face of door 7.At this moment, the wind of supplying with in heating clamber 4 when microwave cooked is the warm braw that magnetron 13 cooling backs are formed, and therefore can more effectively prevent door 7 knot mists.
Here, have such tendency from the wind on air-guiding aisle 18 flow ventilation roads 24, that is, from away from the top plate portion air entry 21 of air-guiding aisle 18 than near in the top plate portion air entry 21 easier inflow heating clambers 4 of air-guiding aisle 18.For this reason, the aperture area of close air-guiding aisle 18 1 sides (right side of Fig. 1) that makes top plate portion air entry 21 as present embodiment is greater than away from air-guiding aisle 18 1 sides (left side of Fig. 1), just can be from flowing into all wind of amount near the top plate portion air entry 21 of air-guiding aisle 18 with away from the top plate portion air entry 21 of air-guiding aisle 18.
Again, owing to will be configured in the indoor lamp 22 of heating clamber 4 intraoral illuminations on the ventilation road 24, therefore the wind through ventilation road 24 also can blow on the indoor lamp 22, can utilize this wind with indoor lamp 22 coolings, and can prevent that steam is attached on the indoor lamp 22.At this moment, owing to indoor lamp 22 is provided on the big position, right side of the aperture area of top plate portion air entry 21 in the ventilation road 24, therefore, wind is blown on the indoor lamp 22 fully, and the light that can utilize indoor lamp 22 to send, through illumination fully in 21 pairs of heating clambers 4 of top plate portion air entry.
Again,, therefore, not only can be convenient to wind, also can guarantee ventilation from air-guiding aisle 18 flow ventilation roads 24 owing to formed the bellying 25 that upwards bloats on the thermal insulation board 23 and coupling part between the air-guiding aisle 18.Owing on this bellying 23, form bend 25a, therefore, can be convenient to front portion again from the distinguished and admirable road 24 of going into to ventilate of air-guiding aisle 18.
On the other hand, baking when cooking, because of not needing that magnetron 13 is cooled off, so cooling fan can be lower than the rotary speed working when microwave cooked.Under this occasion, because the wind of cooling fan 16 is the same when microwave cooked, is to pass through ventilation road 24 to supply with in heating clamber 4, therefore, can prevent that not only heating clamber 4 from including moist air and flowing backwards to ventilation road 24 and then to Machine Room 5, also can be with indoor lamp 22 coolings.And, electric parts 16 grades that are provided in the Machine Room 5 are broken down if heating clamber 4 includes moist air and flows to Machine Room 5.
Again, in the above-described embodiments, because constituting the top board 3e of the interior case 3 of heating clamber 4 top plate portions is made by corrosion resistant plate, and on this top board 3e, formed the printing opacity that is also used as indoor lamp 22 with top plate portion air entry 21 peristome, that forms by punching hole, so no longer need implement the application of antirust usefulness in these top plate portion air entry 21 parts.
When forming the air entry of forming by punching hole on the right plate 3e at the interior case 3 of aludip system, need partly implement the application of antirust usefulness usually at this air entry, but present embodiment does not need to implement the antirust application of using, so can reduce cost.
From above-mentioned explanation as can be seen, since heating device of the present invention be by the top plate portion of heating clamber, configuration above it thermal insulation board and be located at the top plate portion of heating clamber or the protuberance on the thermal insulation board forms the wind of cooling fan anterior ventilation road above air-guiding aisle is guided the top plate portion of heating clamber into, therefore different with the occasion that special-purpose air intake passage is set on the top plate portion of heating clamber, no longer need to be provided with in addition special-purpose air intake passage, not only can corresponding minimizing part number, and can reduce cost.
