The right side of heating clamber 7 is separated by pressure fan outer cover 21, and the right side of pressure fan outer cover 21 constitutes supply fan room 22, and the front end of pressure fan outer cover 21 bends and close the front of supply fan room 22.The upside of heating clamber 7 is separated by top passageway plate 24, and the upside of catheter plate 24 constitutes top passageway 25, and the front end bending of top passageway plate 24 is with the preceding face closure of top passageway 25.Similarly, the downside of heating clamber 7 is separated by foot passage plate 27, and the downside of foot passage plate 27 constitutes foot passage 28, and the front end bending of foot passage plate 27 is with the preceding face closure of foot passage 28.The space that is surrounded by pressure fan outer cover 21, top passageway plate 24 and foot passage plate 27 constitutes support chamber 29.In addition, guide plate 31 is set on the left side of heating clamber 7, the front that the part of this guide plate 31 is set also is closed.

Configuring multi-layer supporting plate 33 along the vertical direction in the above-mentioned support chamber 29 that the central portion of heating clamber 7 forms.Configuration is an armoury wire formula heater 35 as the heating wire of each supporting plate 33 of heating on the downside of the supporting plate 33 that is made of metals such as iron plate or copper coins, and supporting plate 33 and armoury wire formula heater 35 constitute support.Mounting pallet 37 on the supporting plate 33, the food with heated band filling bread etc. placed side by side on pallet 37.

It is propeller type pressure fan 41 that pressure fan is set in supply fan room 22, and the circulation that the circulation of air that this propeller type pressure fan 41 produces is crossed on the pressure fan outer cover 21 is flow through between support chamber 29 and the supply fan room 22 with opening.The driving that drives these propeller type pressure fan 41 rotations is configured in the Machine Room 45 on body 6 right sides with motor 43.This driving is alternately done positive and negative rotation with motor 43 repeatedly by means of timer.In addition, various switches and display unit 49 are set on the front panel 46 of Machine Room 45.

Upside at body 6 is provided with resinous water tank 51, and this water tank 51 is that water injection valve 53 is connected with pipe 54 by switch valve, and pipe 54 extends in the heating clamber 7 always.When water injection valve 53 is opened, the water in the water tank 51 splash in the heating clamber 7.For this water injection valve 53 of switch, on water injection valve 53, connect timer 56 and switch 57.

Armoury wire formula heater 35, propeller type pressure fan 41 and water injection valve 53 are worked simultaneously they are worked respectively, for example, not shown switch is set respectively, or control by the control device of microcomputer etc.

In such stove 1 that constitutes, when baking band filling bread 36 grades,, there is the pallet 37 of bread 36 to be loaded on the supporting plate 33 placed side by side again toasting preceding bread 36 and being emitted on the pallet 37.Then, close insulated door 11, to 35 energisings of armoury wire formula heater and work, as shown in Figure 2, the radiant heat of armoury wire formula heater 35 is from the below heated baking band filling bread 36 of band filling bread 36.So bread 36 is bulging upwards, becomes only shape.Below bread 36, bleach in addition.Before holding bread 36, also can make baffle heater 35 work in advance, stove 1 is carried out preheating.

Like this, at the baking initial stage, only the radiant heat by baffle heater 35 toasts.Behind the baking half way, keep the duty of baffle heater 35, as shown in Figure 3,, make 41 work of propeller type pressure fan to driving with the motor power supply.So the air that blows out from propeller type pressure fan 41 along the solid arrow direction by top passageway 25, foot passage 28 and guide plate 31 guiding, returns pressure fan 41 by becoming hot blast between each supporting plate 33 again.The air output that each supporting plate is 33 is subjected to the influence of guide plate 31 and is even substantially.Like this, hot blast circulates in heating clamber 7.By these hot blasts bread 36 bakings are finished.Yet this propeller type pressure fan 41 can positive and negatively rotate, and blows along the dotted arrow direction on the contrary along the air-supply of solid arrow direction for a moment a little while.Therefore, hot blast contact a little while with band filling bread 36 from the right side a little while and contacts with being with filling bread 36 from the left side, and hot blast can be basically and bread 36 even contact.

In Fig. 4, when the baking French baguette, push switch 57 in the time that timer 56 is set, is carried the signal of telecommunication to water injection valve 53, opens water injection valve 53.So the water that are stored in the water tank 51 fall naturally, drip and supply with heating clamber 7 by managing 54.Be heated to for example about 180 ℃ of high temperature by armoury wire formula heater 35 in the heating clamber 7, the water of supply evaporates at once and becomes water vapour, and heating clamber 7 is heated.

In the present embodiment, illustrational is baking bread, but also can be used for toasting for example pizza of other article.

In the present embodiment, baking stops propeller type pressure fan 41 at the beginning, through after half, makes 41 work of propeller type pressure fan.The working method of this pressure fan can be according to being done suitable change by cooked food, or just blow or the propeller type pressure fan is being stopped to the end always from beginning.Initial air-supply stops also passable halfway.Also can blow repeatedly, out-of-blast.

According to the present invention, because heater is set on support, therefore can heat it from the bread downside on support placed side by side, be baked into the state of bulging upward, shape is fine to be seen.Under the state of heater work, can suitably select the pressure fan duty in addition.Therefore the state that pressure fan stops for example at the baking initial stage, stops pressure fan, toasts out shape bread preferably, in the second half, makes pressure fan work, and it is irregular just can to prevent that bread etc. from toasting.

The air supply direction of above-mentioned pressure fan is changeable, by switching the air supply direction of this pressure fan, changes the loop direction of the air in the heating clamber.At this moment, because hot blast can blow to bread more equably, so can further prevent the generation of the irregular phenomenon of baking of bread etc.

In addition, on aforementioned stove water tank is set, the water that is stored in this water tank is supplied with in the heating clamber.In this case, owing to can therefore can increase the kind of the bread that can cook by steam to the heating clamber humidification.And supplying with water to heating clamber is to be stored in the water tank, therefore stove is connected with water pipe, the setting of stove and mobile comparatively simple.
