Detailed Description

The invention is further described in detail below with reference to the figures and examples.

As can be seen from the figure, the utility model discloses a deep-fry case of hot air has theshell 1 of cuboid shape, and thecasing 1 front portion is thechamber door 2 that can open, and the mid portion ofchamber door 2 is the observation window that transparent material made for know the ripe condition of food at any time in the culinary art process. The front part of thehousing 1 is also provided with a display device (area) 5 for displaying cooking information and machine operation information, for displaying the operation of the machine or information on food cooking, such as temperature, remaining cooking time, etc. The front part of thehousing 1 also has means (areas) 6 for placing the operating buttons for power switches/knobs, temperature setting switches/knobs, and timing switches/knobs etc.

As can be seen from the figure, when thedoor 2 is opened, thecasing 1 is internally provided with acooking cavity 3 which is shaped like a cuboid, areticular food bracket 4 is arranged inside thecooking cavity 3 and used for placing cooked food, and the position of thefood bracket 4 can move up and down to adapt to the food with different volumes or placing modes. There are many convex sand grips in theculinary art cavity 3 left and right sides forplace food bracket 4, and can let it place at different heights.

The space between the left, right, upper, or lower side of thecooking cavity 3 and the housing forms a space (in the figure, it is provided on the right side) for accommodating the control device and the display device. The space between the left and right sides of thecooking cavity 3 and the housing forms a space for accommodating a first hotair generating device 11 and a second hotair generating device 12, respectively, which include a hotair circulating fan 7 and a hot airelectric heating element 8. Wherein, thecooking cavity 3 is provided with ahot air outlet 9 on each of the left and right sides, the hot airelectric heating elements 8 of the first hotair generating device 11 and the second hotair generating device 12 are arranged at the position of thehot air outlet 9, the hot airelectric heating elements 8 are electrified to generate heat, and simultaneously heat the passing air to change the passing air into high-temperature hot air, and the hotair circulating fan 7 blows the hot air into thecooking cavity 3 through thehot air outlet 9.

The hotair circulation fan 7 may be of a centrifugal blower type, or a fan type. An air inlet (10 in fig. 2) for sucking hot air and an air outlet (9 in fig. 2) for blowing out hot air are required (note that the hot airelectric heating element 8 is not shown in fig. 2 for clarity, so as not to be obscured). The circulatingfan 7 is used for treating high-temperature hot air which needs heat-resistant materials, and the driving motors of the circulating fan and the circulating fan cannot bear high temperature and need to be arranged in another normal-temperature space which is connected by a transmission shaft. These are all conventional in the art. Not shown in detail in the drawings.

The bidirectional hot air is blown to thefood 21, and after a period of time, thefood 21 is cooked completely, so that the condition that some parts of the cooked food are over mature, even scorched and even dark, and other parts are not mature when the prior art hot air frying box only provided with a single hot air generating device is used for cooking the food is avoided. The cooking is uniform, and the taste effect of 'scorched outside and tender inside' which is often said can be obtained.

In order to achieve better cooking effect, in the present embodiment, as shown in fig. 4, the installation positions of the first hotair generating device 11 and the second hotair generating device 12 are not symmetrical from side to side (as indicated by a high and a low), so that the hot air forms a better circulation path (as indicated by a plurality of small arrows) in the cooking cavity.

As shown in fig. 5, the first hotair generating device 11 and the second hotair generating device 12 may be installed at left and right asymmetric positions, but the asymmetric positions are different in the angle at which the hot air is blown into the cooking cavity. The hot air can form a better circulation path (as indicated by a plurality of small arrows) in the cooking cavity, so that the cooking efficiency is improved, and the phenomenon of uneven heating is improved.

Whether the cooking effect is uniform or not is also related to the characteristics and shape of the food itself. It is also possible to vary the specific positioning of the "asymmetry" and "different air flow angles" described above, varying the orientation of the "circulation" of the hot circulating air flow in thecooking cavity 3. For example, in fig. 4 and 5, the circulation surface is a vertical surface, if the position or the angle of the hot air blown into the cooking cavity is changed, the air flow circulation surface can be designed to be a horizontal surface or an inclined surface, so that a plurality of spaces for adapting to specific requirements and improving effects exist.

Furthermore, convex or concave air guide surfaces 14 can be arranged above and/or below the interior of the cooking cavity, so that a better circulation path can be formed by hot air in the cooking cavity, the cooking efficiency is improved, and the phenomenon of uneven heating is improved.

Furthermore, convex or concave radiation surfaces 15 can be arranged above and/or below the non-heat source in the cooking cavity, the radiation surfaces 15 are heated by flowing hot air in a convection mode, and the radiation surfaces are made of materials with high blackbody coefficients, so that additional radiation heating is provided, and a better and more uniform cooking effect is achieved. In the figure, theradiation surface 15 is a plane, and may have a shape having a concave-convex shape, an alternate concave-convex shape, and an enlarged area. The enlarged area also increases the radiation effect (not shown in the figure).

The main features, technical principle and advantages of the present invention have been described above with reference to the embodiments, which are not intended to be limiting the present invention, any modification made by the present invention, equivalent replacement and improvement, should fall within the scope of the present invention.
