Specifically, in this embodiment, the shape of the hot air cover 41 is a volute, the air outlet 412 is formed with a hot air baffle wall 45 extending along the tangential direction thereof, one end of the hot air baffle 42 connected to the hot air cover 41 is formed with an air guide channel 43 and an air guide channel 44 separated by the hot air baffle wall 45, the other side walls of the air guide channel 43 and the air guide channel 44 are respectively inclined from top to bottom outwards, and the extending direction of the air guide channel 43 faces the air outlet direction of the hot air cover 41, wherein the air guide channel 43 is communicated with the air guide channel 44, the top wall of the air guide channel 43 is uniformly inclined from top to bottom towards the back of the liner 1 (the inclined angle relative to the horizontal plane is 160 ° and is reduced from 30mm to 8 mm), and the top wall of the air guide channel 44 is parallel to the back of the liner 1. The hot air thrown out by the hot air cover 41 enters the air guide channel 43, and as the top wall of the air guide channel 43 is uniformly inclined from top to bottom towards the back of the inner liner 1, part of the hot air is extruded and flows into the air guide channel 44, the hot air entering the hot air channel 420 is separated into two layers by taking the hot air blocking wall 45 as a boundary, one layer is led out downwards through the air guide channel 43 along the original tangential direction of the centrifugal fan 6, and the other layer is led out downwards to the right along the air guide channel 44, so that the hot air is distributed along the width direction of the hot air channel 420 as uniformly as possible, then flows smoothly along the extension section, and finally is uniformly blown out from the hot air outlet 421.
In this embodiment, the hot air inlet 411 is a set of holes formed on the front surface of the hot air cover 41, the holes are arranged in a circular array and are concentric with the centrifugal fan 6, the holes of the hot air inlet 411 are radial from inside to outside, and the aperture increases gradually from inside to outside. So that hot air in the upper layer of the liner 1 can enter the hot air cover 41 as much as possible.
In order to smoothly throw the hot air from the air outlet 412 of the hot air hood 41 after the centrifugal action of the centrifugal fan 6, the centrifugal fan 6 is eccentrically disposed with respect to the hot air hood 41, the back heating device 5 is a circular heating pipe, and the back heating device 5 is concentrically disposed with the centrifugal fan 6. The molded line of the spiral case-shaped hot air cover 41 is an archimedes spiral line, so that the section of the hot air cover 41 is continuously enlarged until the position of the air outlet 412 reaches the maximum, the air flow can smoothly flow out, and the pressure loss caused by the extrusion of the hot air flow at the air outlet 412 is prevented.
In this embodiment, in order to further uniformly draw out the hot air flow from the hot air outlet 421, the hot air outlet 421 is a long hole opened along the width direction of the hot air baffle 4, and the lower hole edge of the long hole extends inward along the length direction to form the hot air guide 423. When the hot air flow moves to the hot air outlet 421, since the hot air outlet 421 is a long hole, the flow speed of the hot air flow can be increased and the wind pressure can be increased, and meanwhile, the hot air is guided by the hot air guide bars 423, so that the hot air can be blown out from the hot air outlet 421 more uniformly. In addition, since the tray 21 is horizontally placed in the inner container 1, in order to make the hot air blown out from the hot air outlet 421 heat the food on the tray 21 better, the hot air guide 423 forms an angle of 70 ° to 80 ° (preferably 75 ° in the present embodiment, as shown in the angles α and β of fig. 10) with the plate surface of the hot air baffle 4 where it is located, so that the hot air blown out from the hot air outlet 421 flows out in a nearly horizontal direction and is blown through the food on the tray 21 uniformly.
Further, the number of the hot air outlets 421 is two, and the two hot air outlets 421 are arranged in parallel and spaced up and down, wherein the height (H1) of the hot air guide 423 of the hot air outlet 421 positioned at the upper part is lower than the height (H2) of the hot air guide 423 of the other hot air outlet 421, so that a hot air gap 422 is formed between the hot air guide 423 at the upper part and the back surface of the inner container 1, and preferably, H1 is 1/3 of the height of H2. So that the hot air which does not pass through the upper hot air guide 423 can be blown to the lower hot air outlet 421 through the hot air gap 422 and blown through the grill pan positioned at the lower layer under the guide of the lower hot air guide 423. Further, in the present embodiment, the distance between the hot air outlet 421 located at the upper portion and the air outlet 412 of the hot air hood 41 is 120mm, the distance between the two hot air outlets 421 is 44mm, the area of the hot air outlet 421 located at the upper portion is 1342mm 2, the area of the hot air outlet 421 located at the lower portion is 2013mm 2, the air outlet volume of the hot air outlet 421 located at the upper portion is 0.11kg/s, the air outlet volume of the hot air outlet 421 located at the lower portion is 0.12kg/s, and the air outlet of the upper and lower hot air outlets 421 is uniform, as shown in the wind field simulation diagram of fig. 12. The tray 21 is opposite to the middle of the two hot air outlets 421, so that the wind outlet of the hot air outlet 421 above the tray 21 (5 mm higher than the top surface of the tray 21) uniformly blows across the top surface of the tray 21, and the wind outlet of the hot air outlet 421 below the tray 21 (5 mm lower than the bottom surface of the tray 21) uniformly blows across the gap between the tray 21 and the bottom heating device 22, thereby heating the food on the tray 21 in cooperation with the bottom heating load 2.
As can be seen from the above, the oven of the present invention is provided with the rotatable tray 21, and the high wind speed and large flow of hot air from the two hot air outlets 421 can be blown to the door of the oven, and is affected by the negative pressure area inside the hot air cover 41, so that the hot air flows to the hot air inlet 411 of the hot air cover 41 above the door, forms a large hot air circulation inside the oven, uniformly coats the tray 21, and uniformly heats the food on the tray 21.
