Detailed Description

The technical scheme of the invention is described in the following by combining the drawings and specific embodiments:

the fryer of the present invention is a semi-fryer, "semi-frying" meaning a cooking mode in which only a portion of the food is (partially and/or temporarily) immersed in the cooking medium during the cooking cycle, i.e., the food is wetted by the cooking medium and partially immersed in the cooking medium. Thus, the working principle of the semi-frying pan of the invention is different from that of the traditional dry frying pan and deep fryer, and the semi-frying pan of the invention can switch at least part of food to be cooked in two cooking environments of dry frying and deep frying, so that the cooked food has the advantages, taste and color of dry frying and deep frying.

The first embodiment is as follows:

referring to fig. 1 to 3, the semi-fryer of the present embodiment comprises a main body 1, a main heating device 2, a stirring device 3 and a containing device 4 for containing food to be fried are arranged in the main body 1, and the main heating device 1 at least provides main cooking heat for the food; stirring device 3 comprises stirring blade 301 arranged at the bottom of receiving device 4, bottom surface 3011 of stirring blade 301 and bottom surface 401 of receiving device 4 are designed to have a distance H between them, which distance H allows part of the grease to collect at the bottom of receiving device 4 to form oil pool 6, receiving device 4 and stirring device 3 are designed to rotate relative to each other, thereby mixing the food with the grease and stirring part of the food to make it directly contact with oil pool 6.

Compared with the prior art, the semi-frying pan of the invention forms the oil pool 6 at the bottom of the accommodating device 4 in the cooking process, at least part of food to be cooked can be switched between two cooking environments of dry frying and deep frying in the cooking process, so that the cooked food has the advantages of dry frying and deep frying, mouthfeel and color formation, the food contacted with the oil pool 6 can absorb heat from high-temperature grease, the part of food is cooked more quickly, and more food can absorb heat from the oil pool 6 by stirring of the stirring device 3, thereby shortening the cooking time and improving the cooking efficiency.

The height of the spacing H is a key parameter, influences the effects of dry frying and deep frying, and the spacing H is too small, the depth of the oil pool 6 is not enough, and the deep frying effect is not obvious; the spacing H is too large, and the dry frying effect is not obvious; therefore, the oil pool 6 formed in the range of 0.75mm-14.25mm can realize the best cooking effect of dry frying and deep frying on the food, and meet the requirements of people for cooking different foods.

The main heating means 2 are designed to generate a heat flow which impinges directly on at least a part of the food to be cooked, providing at least a major part of the cooking heat to the food. The "heat flow" herein means a directional flow of heat, which may occur from an infrared heater, or may be a flow of hot air. The use of a heat flow as at least a major part of the cooking heat has an effectively controlled dynamic characteristic compared to the use of cooking heat obtained entirely by static heating.

The body 1 is provided with a lid 5 having a closed position, in which the lid 5 forms together with said containing means 4 a sealed cavity for the food to be fried, and an open position, in which the food can be placed in or taken out of the containing means 5.

Preferably, the cover 5 of the present embodiment is connected to the body 1 by a hinge mechanism, so that the cover 5 can open or close the receiving means 4 conveniently.

In this embodiment, the accommodating means 4 is installed at a fixed position with respect to the main body 1, while the stirring means 3 is rotatable with respect to the accommodating means 4, and the stirring means 3 is rotationally driven by a driving motor.

As another embodiment, the stirring means 3 is mounted in a fixed position with respect to the body 1, while the containing means 4 is rotatable with respect to said body 1, and the containing means 4 is driven in rotation by a drive motor.

In this embodiment, the main heating device 2 is provided on the lid 5, the main heating device 2 has an infrared heater, and when the lid 5 is in the closed position, the infrared heater that is energized irradiates far infrared rays toward the accommodating device 4. Of course, in other embodiments, the main heating device 2 may be disposed at other positions of the main body, and it is within the scope of the present invention that far infrared rays can be irradiated to the accommodating device 4.

As another embodiment, the heat flow is a hot air flow, and the main heating means comprises a centrifugal fan forming an air flow by sucking air in through at least one air inlet provided on the main body and then discharging the air from an exhaust passage provided on the main body to the accommodating means; a heating element is arranged in the exhaust passage and heats the air flow to form a hot air flow directly blowing to the accommodating device. In order to ensure the heating effect, the heating element is arranged at a position close to the outlet of the exhaust passage, so that the temperature loss of the hot air flow blown to the accommodating device is smaller.

Example two:

referring to fig. 4 to 6, the present embodiment is different from the first embodiment in that: the distance between the bottom surface 3011 of the stirring vanes 301 and the bottom surface 401 of the container 4 is varied, the bottom surface 3011 of the stirring vanes 301 is obliquely arranged with respect to the bottom surface 401 of the container 4, and the bottom surface 3011 of the stirring vanes 301 is obliquely inclined upward from the middle portion along the side portions, and the maximum small distance Hmin and the maximum distance Hmax between the bottom surface of the stirring means and the bottom surface of the container are in the range of 0.75mm to 14.25 mm. By arranging the bottom surface 3011 of the stirring blade 301 obliquely with respect to the bottom surface 401 of the accommodating means 4, mainly frying is performed at a portion with a small H, and more frying effect is maintained at a portion with a large H, while the general stirring means 3 can stir food from a portion with a small H to a portion with a large H by turning over the food, so that the two cooking modes can be combined and switched better. Meanwhile, the stirring blade 301 stirs the grease in the oil pool 6 from the part with small H to the part with large H in the stirring process, so that the oil pool 6 flows to contact with more food, the temperature of the food can be increased rapidly, and the cooking efficiency is improved.

Other technical features are the same as those of the first embodiment and will not be described in detail herein.

Example three:

referring to fig. 7 to 9, the present embodiment is different from the second embodiment in that: the bottom surface 3011 of the stirring blade 301 is inclined upward from the side portion along the middle portion,

other technical features are the same as those of the embodiment and will not be described in detail.

Example four:

Preferably, the distance H' min between the lower side Wmin of the inclined surface W and the bottom surface 401 of the accommodating means 4 is in the range of 0.75mm-14.25mm, and Wmax in fig. 10 is the upper side of the inclined surface W, because the oil bath 6 formed in the range of 0.75mm-14.25mm can achieve the best cooking effect of dry frying and deep frying for food, satisfying the needs of people for cooking different foods. Preferably, the inclined plane W has an inclination angle of 2 to 15 degrees, and the stirring effect is best within this angle range.

In addition, the scheme of the present embodiment can also be applied to the second embodiment and the third embodiment.

Variations and modifications to the above-described embodiments may occur to those skilled in the art, which fall within the scope and spirit of the above description. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and variations of the present invention should fall within the scope of the claims of the present invention. Furthermore, although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
