Alternatively, as shown in fig. 1 and 2, the air outlet a2 may be disposed at the front end of the housing 10, and disposed obliquely downward, and the air outlet a2 is provided with a wind sweeping blade a3, so that the air supply range can be enlarged, and the comfort of the cooker can be improved.

Preferably, as shown in fig. 2, the oil baffle 20 is located at the air inlet to form an annular air inlet channel, so that kitchen air can uniformly enter the air duct of the air conditioner around the oil baffle 20, which is more beneficial for the kitchen air to uniformly bring the oil smoke into the flow guide surface of the oil baffle 20, and facilitates the condensation and recovery of the oil smoke.

Further, evaporimeter 30 with be equipped with between the oil baffle 20 and be used for covering the filter screen 50 in wind channel through setting up filter screen 50, can prevent to lack inside the oil smoke entering air conditioner that does not keep off oil baffle 20, the comdenstion water of evaporimeter 30 instils into filter screen 50 earlier, makes a small amount of oil smoke condensation that adheres to on filter screen 50 oil drip instil into on domatic 22 to from dripping and comdenstion water domatic 22 following current flows into the border department of oil baffle 20 and collects, finally falls into collection oil groove 40 in, can avoid setting up filter screen 50 in the traditional air conditioner and need often dismantle abluent problem, reduced filter screen 50's dismantlement cleaning frequency, also reduced the air inlet resistance of air conditioner simultaneously (when traditional air conditioner filter screen 50 is stained with more oil stain, air inlet resistance is great).

In this embodiment, the concave structure may be formed by a conical surface, an arc surface such as a bowl-shaped structure, or other shapes having a gradually expanding structure, which is not limited herein.

The recessed structure in this embodiment is described by taking a tapered surface as an example, but is not limited to the tapered surface structure, and is described below with reference to fig. 5 to 9.

The sloping surface of the oil baffle plate 20 and the depressed structure are rectangular pyramids or approximate rectangular pyramids (the top of the rectangular pyramids is a circular arc or a plane), wherein the leeward side of the oil baffle plate 20 swells towards the air inlet direction of the kitchen wind, the windward side thereof is depressed towards the air inlet direction of the kitchen wind, the depressed structure is arranged downwards, oil drops are convenient to adhere to and condense into oil drops on the conical surface (flow guide surface) of the depressed structure, water is also condensed on the surface of the conical surface to form water, and the condensed oil drops and water flow downwards along the conical surface (flow guide surface) to the edge under the self weight to be collected and dripped into the water collecting oil groove 40.

Further, be equipped with a plurality of downwardly extending's water conservancy diversion muscle 23 on the water conservancy diversion face 21, water conservancy diversion muscle 23 is along the depressed structure distributes all around, and two adjacent water conservancy diversion muscle 23 form guiding gutter a.

Furthermore, inclined planes 231 extending along the length direction of each flow guide rib 23 are formed on two sides of each flow guide rib 23, the inclined planes 231 of two adjacent flow guide ribs 23 enclose the flow guide groove a, and the width of the flow guide groove a gradually decreases towards the bottom of the flow guide groove.

It should be particularly noted that the inclined surface 231 may be a plane or an arc surface, and the arc surface may be a concave arc surface or a convex arc surface, that is, the side wall of the diversion trench a is arc-shaped on the cross section. The inclined plane 231 in this embodiment is preferably a plane, which can achieve a better flow guiding effect and avoid the accumulation of oil droplets.

Furthermore, the included angle between the two inclined planes is beta, and the beta is more than or equal to 90 degrees and less than or equal to 150 degrees. The overlarge angle beta is not beneficial to flow guiding, and the liquid drops with the undersized angle have larger kinetic energy when converging to the flow guiding ribs and are easy to directly drop. In the embodiment, the best mode is that the value range of beta is more than or equal to 110 degrees and less than or equal to 130 degrees.

In an embodiment of the present invention, two inclined planes on each of the flow guiding ribs 23 are symmetrical with respect to the flow guiding rib.
