Description

A kind of hot blast electric oven

Technical field

The utility model belongs to the electric oven technical field, especially relates to a kind of hot blast electric oven.

Background technology

Baked foods is because its unique mouthfeel is very popular.The technology of existing indoor making baked foods mainly is to utilize micro-wave oven or light-wave cooker etc. simply to toast.But because its baking principle and pyrotechnics baking have very large difference, so its mouthfeel is relatively poor.And because the cleaning oil stain is inconvenient, also be not suitable for toasting crossing oil food, so it is basic or in the fried mode of tradition as main to cross oil food, even but this kind mode changes deep frying pan into still wastes very much edible oil.

The designer has developed a kind of baking box for this reason, and its basic principle is to blow on the food by the heat that fan produces heater element to heat.For example United States Patent (USP) 4374319 discloses a kind of baking box February 15 nineteen eighty-three, its scheme is in the food chamber bottom baffles to be set, food chamber top or side arrange opening, opening part arranges fan, fan arranges heating element heater, chamber is circulation canal around the outside, on the sidewall of bottom baffles and/or chamber pore is set.The principle of this scheme is: make heating element heater hot-air on every side enter circulation canal, then pass pore and enter in the food chamber, become cold air through after the food, the recycling fan is from the opening part sucking-off, through the heating element heater heating, circulate and so forth again, reach the purpose of heat food.But the heating element heater in this scheme is positioned at the outside of food chamber, and the circulation of pore is too small, greatly reduces its efficiency of heating surface.

Also have patent CN 101500462 B to disclose a kind of air guide member for preparing the equipment of food and be used for this equipment on January 25th, 2012.The principle of the operation principle of this scheme and United States Patent (USP) 4374319 is basic identical, just heating element heater is arranged in the food chamber.And its principal character is in circulation canal, and the below of food chamber is provided with an air guide member, is intended to guide air upwards to flow.But this structure can cause Air Flow too concentrated, and the heat that food is received is inhomogeneous, causes the well-done degree varies of food; And its structure is too complicated, has increased material cost and the manufacturing cost of product; The simultaneously also cleaning of inconvenient product.

In addition, patent CN101360440 disclosed a kind of cooking apparatus with agitating device and correlation technique on February 4th, 2009.Wherein the scheme of cooking apparatus is that main heater is set above the food chamber, and the thermal current that is heated is guided in the food chamber by the air inlet of food chamber side, and its principal character is that rabbling mechanism is set in the food chamber, thereby reach the while stirring purpose of heating, food is heated evenly.But this structure is too complicated, and manufacturing cost is high, and very inconvenient cleaning.

The utility model content

In order to solve above-mentioned the deficiencies in the prior art, it is more even that the utility model has designed a kind of heating, hot blast electric oven simple in structure.

The technical solution of the utility model is: a kind of hot blast electric oven, comprise housing (1), be provided with the thermal wall (2) that surrounds chamber in the housing (1), be provided with wind scooper (7) in the chamber, wind scooper (7) is provided with air outlet (4), air outlet (4) below is provided with heater element (5), and air outlet (4) top is provided with centrifugal blower (6); The plug-type food basket (8) that is provided with in the below of wind scooper (7), the bottom surface of food basket (8) is provided with air-vent, and the side is enclosed construction; Leave the space between the bottom of food basket (8) and chamber, form hot-air channel (3) between bottom surface, side and the thermal wall (2) of food basket (8); The bottom of described chamber is planar structure, perhaps is concave structure.

Heater element in this programme (5) heating, and make its ambient air heating, then by centrifugal blower (6) hot-air is passed through the bottom that hot-air channel (3) takes chamber to, the bottom surface of passing again food basket (8) enters in the food basket (8), thus the food in the heat food basket (8).Because hot-air is through hot-air channel (3), rather than directly blow on the food on every side from heater element (5), reduce the local many and burned problem of heat that receives of food, and the bottom of chamber is plane layout, make entering in the food basket (8) that hot-air disperses more, make being heated of food more even.Simultaneously, planar structure is simpler, and processing is with low cost easily.

Above-mentioned food basket (8) side is provided with heat insulation handle (9), to be user-friendly to.

The motor section of above-mentioned centrifugal blower (6) is located at the outside of thermal wall (2), thereby avoids hot-air that motor is exerted an influence, and increases the service life; The blade part of centrifugal blower (6) is located between wind scooper (7) and the thermal wall (2), is conducive to strengthen the flowability of air, improves the efficiency of heating surface.

The corner of the inner surface of above-mentioned chamber is arc transition, makes air be more prone to circulation.

Above-mentioned housing (1) is provided with guidance panel.

The bottom surface of above-mentioned food basket (8) is network structure or lattice-shaped structure, so that the easier bottom surface of passing of air.

The bottom concave surface structure of above-mentioned chamber, its concave surface are curved surface or inclined-plane, perhaps are wavy surface.

The utility model compared with prior art mainly has following beneficial effect: both can toast without oil food and use as baking oven, can toast again oil food as using without deep fryer, being heated of food is more even; Structure is simpler, and processing is with low cost easily; Avoid hot-air to affect motor, increase the service life.
