Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1, the broil cooking device is a cooking device with a broil function, such as an oven, a steam oven or an all-in-one machine for steaming, broil and frying, and the broil cooking device in this embodiment is a steam oven.

As shown in fig. 1, the cooking device includes an inner container 1, a hot air baffle 2, a grill 3, an air guide 4, a lower fan 5, and an upper fan 6. Wherein the inner container 1 has a cooking chamber 10 with an open front side. The hot air baffle 2 is arranged in the cooking cavity 10, and a hot air chamber is formed between the hot air baffle and the rear wall plate of the inner container 1, the form of the hot air chamber is specifically referred to Chinese invention patent ZL202011069510.6 of the prior application of the applicant, and a hot air blower and a heating pipe are arranged in the hot air chamber.

As shown in fig. 2, fig. 3 and fig. 6, the position of the hot air baffle 2 near the center is provided with a plurality of air inlets 23 communicated with the hot air chamber, and the position of the hot air baffle 2 near the bottom is provided with an air outlet, the air outlet of the present embodiment includes a first air outlet 21 and a second air outlet 22 both extending transversely, the first air outlet 21 and the second air outlet 22 are arranged at intervals from left to right, and the first air outlet 21 is located below the second air outlet 22.

As shown in fig. 1, the air guide 4 is disposed in the cooking cavity 10 and has a disc shape with an open top, and specifically, as shown in fig. 2 and 3, the air guide 4 has a cavity 40 with an open top, which is an air outlet 400 of the cavity 40. The grill 3 is provided in the cooking chamber 10, is arranged laterally, and covers the top opening of the wind guide 4, and is used for placing food. The rear wall plate of the air guide member 4 is provided with a first air inlet 401 and a second air inlet 402 which are communicated with the cavity 40, the first air inlet 401 and the first air outlet 21 are correspondingly arranged, the second air inlet 402 and the second air outlet 22 are correspondingly arranged, along the fluid flow path, the first air inlet 401 is located at the downstream of the first air outlet 21, the second air inlet 402 is located at the downstream of the second air outlet 22, and the first air inlet 401 and the second air inlet 402 both extend transversely and are located at the upstream of the air outlet 400. In addition, a gap 01 is left between the rear wall plate of the air guide 4 and the hot air baffle 2, and a plurality of third air inlets 43 communicated with the accommodating cavity 40 are formed in the bottom wall of the air guide 4.

As shown in fig. 4, the lower fan 5 is disposed in the cavity 40, and is disposed corresponding to the first air inlet 401, and rotates relative to the air guide 4 under the pushing of the air flow flowing out from the first air inlet 401, specifically, the lower fan 5 is rotatably disposed at a position near the center of the grill 3, and the rotation axis of the lower fan 5 extends vertically. The fan blade of the lower fan 5, which is located on the left side of the rotation axis of the lower fan, is located on the flow path of the fluid flowing out of the first air inlet 401, so as to drive the hot air flow to flow upwards when rotating. As shown in fig. 4, the upper fan 6 is disposed in the cavity 40, is located above the lower fan 5, is coaxially disposed with the lower fan 5, and is disposed corresponding to the second air inlet 402, and rotates in a direction opposite to the rotation direction of the lower fan 5 under the pushing of the airflow flowing out from the second air inlet 402, and the fan blade of the upper fan 6 located on the right side of the rotation axis of the upper fan is located on the flow path of the fluid flowing out from the second air inlet 402, so as to drive the hot air to flow upward when rotating. Thus, the hot air flows upwards continuously under the action of the lower fan and the upper fan.

Further, as shown in fig. 4, the upper fan 6 and the lower fan 5 are each disposed to be movable up and down with respect to the grill 3. When the upper fan 6 is at the highest position and the lower fan 5 is at the lowest position, a space 02 is left between the bottom edge of the protruding shaft 51 and the bottom wall of the upper fan 6. Specifically, a sleeve 31 is formed to extend downward from a position near the center of the bottom of the grill 3, the upper fan 6 has an extension shaft 61 extending upward and located inside the sleeve 31, the extension shaft 61 is a rotation shaft of the upper fan 6, the lower fan 5 has a protruding shaft 51 extending upward and coaxially arranged with the extension shaft 61, and the upper fan 6 has a slot 62 below the extension shaft 61 for inserting the protruding shaft 51 therein. The bottom wall of the housing 40 has a fixing shaft 404 extending upward and coaxially arranged with the protruding shaft 51, and the lower fan 5 has a mounting groove 52 into which the fixing shaft 404 is inserted at a position corresponding to the fixing shaft 404. The grill 3 is in interference fit with the air guide 4, so that the air guide 4, the lower fan 5, the upper fan 6 and the grill are connected together, and the lower fan 5 and the upper fan 6 are not separated in the rotating process.

As shown in fig. 5, when the air heater in the hot air chamber rotates, air in the inner container 1 enters from the air inlet 23 of the hot air baffle 2, and is heated by the heating pipe in the hot air chamber and then is exhausted from the first air outlet 21 and the second air outlet 22 at both sides, at this time, the hot air coming out from the first air outlet 21 of the hot air baffle 2 reaches the first air inlet 401 of the air guide 4, and only the lower fan 5 is driven to rotate counterclockwise (because the first air inlet 401 is at a certain distance from the upper fan 6, the upper fan 6 cannot be blown), the air at the bottom of the air guide 4 is driven by the fan blades of the lower fan 5 to flow upward, and the lower fan diffuses the upward hot air to the periphery. The hot air flowing out from the second air outlet 22 of the hot air baffle 2 reaches the second air inlet 402 of the air guide member 4, and only drives the upper fan 6 to rotate clockwise (because the second air inlet 402 is at a certain distance from the lower fan 5, the lower fan 5 cannot be blown), the lower fan 5 drives the upward hot air to continue flowing upwards, the upward flowing hot air is further accelerated, the hot air is diffused all around, the heating of the grill 3 is increased, the bottom and the side edges of the food on the grill can have the continuous flowing of the hot air, and finally the food on the grill is heated more uniformly. In addition, the up-down circulating hot air and the front-back convection of the hot air baffle 2 can accelerate the temperature rise of the liner.

When the air heater rotates at a high speed, the lower fan 5 and the upper fan 6 both move upward under the influence of the air volume, at this time, the lower fan 5 deviates from the corresponding first air inlet 401, and the upper fan 6 deviates from the corresponding second air inlet 402, at this time, the influence of the air volume at the high speed on the rotating speed of the upper and lower fans in the air guide 4 is weakened, and the rotating speed of the upper and lower fans is still basically maintained at the rotating speed when the air heater rotates at a low speed, so that the food cannot be blown away.

Directional terms such as "front", "rear", "upper", "lower", "left", "right", "side", "top", "bottom", and the like are used in the description and claims of the present invention to describe various example structural portions and elements of the present invention, but these terms are used herein for convenience of description only and are determined based on example orientations shown in the drawings. Because the disclosed embodiments may be arranged in different orientations, these directional terms are for illustrative purposes only and should not be construed as limiting, and for example, "upper" and "lower" are not necessarily limited to orientations opposite or consistent with the direction of gravity.
