Description

Wind-guiding lid, lid and cooking utensil

Technical Field

The utility model relates to a small household electrical appliances field particularly, relates to a wind-guiding lid, lid and cooking utensil.

Background

At present, cooking appliances with a baking function generally adopt hot air to heat food. Among the correlation technique, designed a lid, the front side of lid below is provided with the air outlet towards culinary art chamber, and the food heat supply in the intracavity is given for culinary art to the hot-blast heat that blows off in the air outlet to reach the effect of toasting.

However, the hot air circulation rate of the existing air inlet structure is slow, so that the heating efficiency of the hot air to food in the cooking cavity is low, and the use experience of a user is poor.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide an air guiding cover, a cover and a cooking utensil to solve the problem of low cooking efficiency of the cooking utensil in the related art.

In order to achieve the above object, according to one aspect of the present invention, there is provided a wind scooper including: wind scooper body, this internal air-out passageway that is provided with of wind scooper, the passageway diapire of air-out passageway is the decurrent extension gradually in the air-out direction, the passageway diapire has the first point D1 that is close to the air inlet department of air-out passageway and the second point D2 that is close to the air outlet department of air-out passageway, first point D1 and second point D2 are in the same vertical plane M of wind scooper, the curve that is located between first point D1 and the second point D2 of passageway diapire is the steepest curve.

Use the technical scheme of the utility model, when the air current blew in the air-out passageway, can be preferential and the contact of the passageway diapire of air-out passageway, the passageway diapire can play the guide effect to the air current, makes it remove to air outlet department. Because the passageway diapire is crooked extension downwards gradually in the air-out direction, compare with the inclined plane, the air current can obtain bigger acceleration when flowing along the curved surface, and the time that consequently the air current used when reaching the air outlet is shorter. The passageway diapire in this embodiment still includes the fastest curve, and this kind of structure can make the time that gas flows to the air outlet from the air inlet department of air-out passageway the shortest, therefore the design of above-mentioned wind-guiding lid body can promote the velocity of flow of air current in the air-out passageway in the at utmost to promote the circulation efficiency of the air current in the cooking utensil, and then promote cooking utensil's culinary art efficiency.

Further, the steepest curve is a locus defined by a fixed point on the boundary of a circle when the circle moves along a straight line, and the radius R of the circle is between 15mm and 25 mm. Among the above-mentioned structure, because the extending direction and the horizontal direction parallel and level of passageway diapire outer fringe, if the radius R undersize of circle, then can make the length undersize of passageway diapire, correspondingly lead to the area undersize of wind-guiding lid for the wind-guiding lid can only be used in the less cooking utensil of volume. If the radius R of the circle is too large, the length of the bottom wall of the channel is too large, and accordingly the area of the air guide cover is too large, so that the area of the cooking appliance is too large, and the miniaturization design of the cooking appliance is not facilitated.

Further, the bottom wall of the channel is a surface of revolution, and the generatrix of the surface of revolution comprises the fastest curve.
