Description

Air fryer with uniform baking temperature

Technical Field

The utility model belongs to the technical field of domestic cooking appliance, especially, relate to an air that toasts the temperature and explodes pot.

Background

With the improvement of living standard, various household electrical cooking appliances, such as electric ovens, electric chafing dishes, frying and baking machines, are emerging continuously. The air fryer is a new household cooker in recent years, and generally comprises a shell at the bottom, an inner pot assembly arranged in the shell, and an upper cover assembly covered at the top of the shell, wherein the upper cover assembly comprises a reflecting cover with a downward opening, a heating element arranged in the reflecting cover and a centrifugal fan, and the inner pot assembly comprises an inner pot and a grill arranged at the bottom of the inner pot. When the oil-free baking pan is used, food is placed on the baking rack of the inner pan and the upper cover assembly is covered, the heating element generates heat at the moment, the centrifugal fan is started to blow out high-speed airflow, the high-speed airflow is changed into downward airflow under the action of the reflecting cover, and the heating element changes the downward airflow into high-temperature hot air, so that the food on the baking rack is baked without oil.

However, the existing steam air-frying still has the following defects: the high-speed air flow blown by the centrifugal fan is guided downwards by the edge of the reflector and is changed into high-temperature air flow by the heating element. That is, the high temperature air flows downwards along the side wall of the inner pot to form primary hot air, the temperature of the primary hot air is reduced after the primary hot air blows over the food materials around the grill, the primary hot air rises upwards again from the middle of the inner pot to form secondary hot air, the secondary hot air bakes the food materials in the middle of the grill, the secondary hot air is sucked upwards by the centrifugal fan, and the secondary hot air flows downwards along the side wall of the inner pot again under the driving action of the centrifugal fan and the secondary heating of the heating element, so that the food on the grill is heated and baked in a continuous cycle. It will be appreciated that the temperature of the primary hot air flowing down the side walls is highest in the inner pan, and accordingly the food material on the grill near the side walls of the inner pan will cook faster, while the food material in the middle of the grill will cook slower due to being subjected mainly to the roasting by the secondary hot air having a lower temperature.

That is, the temperature of the air flowing over the food on the grill is high at the periphery and low at the center, resulting in non-uniform maturity of the food on the grill.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a fry pot of even air of toasting temperature is favorable to forming the even toasting of temperature to the edible material on the gridion, makes edible material can become ripe in step to promote the taste of edible material processing, and simple structure, convenient processing and manufacturing.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an air that toasts temperature is even explodes pot, includes the shell, sets up interior pot subassembly in the shell, sets up the upper cover subassembly at the shell top, the upper cover subassembly includes the upper cover, sets up bowl, the electric heating element who sets up in the bowl in the upper cover, by motor drive's centrifugal fan, the inside wall of bowl constitutes the main water conservancy diversion face that makes the air current downflow that centrifugal fan blew off, is equipped with at least one vortex arch on the inside wall of bowl, the vortex arch is including the vice water conservancy diversion face that makes the air current downflow that centrifugal fan blew off.

It is known that when the electric heating element and the centrifugal fan are started, the high-speed airflow blown by the centrifugal fan is heated by the electric heating element and is changed into the baking hot air which is downwards turned into the inner pot through the guiding function of the main flow surface formed by the inner side wall of the reflecting cover. Because the utility model discloses it is protruding to set up the vortex on the inside wall of bowl, and the vortex has vice water conservancy diversion face protruding upward. Thus, except that one part of the high-speed airflow blown by the centrifugal fan is guided by the main flow guide surface to flow downwards along the inner side of the inner pot, the other part of the high-speed airflow blown by the centrifugal fan is guided by the auxiliary flow guide surface on the turbulence protrusion to flow downwards into the inner pot.

It can be understood that, because the distances between the auxiliary flow guide surface and the main flow guide surface are inconsistent with the center of the grill, primary hot air with a larger range can be formed on the grill, and the uniform roasting of food materials on the grill is facilitated.

Particularly, in the prior art, when the high-temperature air flows downwards along the side wall of the inner pot under the action of the reflecting cover, the high-temperature air flow is basically in a stable laminar state, so that the area of the grill corresponding to the primary hot air is relatively small. And the utility model discloses because it is protruding to set up the vortex at the bowl inside wall, consequently, when the high-speed air current that centrifugal fan sent out blows on the bowl, vortex protruding wherein can form strong vortex effect to high-speed air current, at this moment, the air current in the pot is turbulent state in the downward entering, when the air current reachs the edible material department on the gridion downwards, can be because of the diffusion of turbulent effect to make the once hot-blast basic action of high temperature on the edible material of whole gridion, therefore can ensure to eat the even unanimity of material culinary art.

Preferably, the reflector comprises a top wall and an annular inner side wall extending downwards from the edge of the top wall, the annular inner side wall forms the main guide surface, the turbulence protrusion extends downwards from the top wall to the edge of the inner side wall, and the circumferential side surface of the turbulence protrusion forms the auxiliary guide surface.

It will be appreciated that the reflector is preferably made of a metal such as stainless steel to withstand the high temperatures of the electrical heating elements. Because the bowl includes roof and annular inside wall to the vortex is protruding certainly the roof downwardly extending to the edge of inside wall, therefore make the bowl roughly be shallow dish shape, and then be convenient for the bowl and the vortex is protruding to be made through conventional panel beating stretch forming technology an organic whole, is favorable to simplifying the manufacturing of bowl. In addition, the top wall can guide the high-speed airflow blown out by the centrifugal fan to the inner side wall, and can effectively reflect upward heat radiation generated by the electric heating element to heat the high-speed airflow downwards, so that the heat efficiency of the electric heating element is improved. The annular inner side wall can make the high-speed airflow sent by the centrifugal fan bend downwards to enter the inner pot. When the centrifugal fan is started, high-speed airflow forming a certain included angle with the radial direction is formed, and the high-speed airflow forms high-speed rotation in the reflector and flows downwards at the same time. Certainly, the inner side wall should be provided with a certain inclination, so that the inner side wall is convenient for stretching and forming, and the wind resistance of high-speed airflow during turning can be reduced as much as possible.

Preferably, the secondary flow guide surface of the turbulent flow protrusion comprises two turbulent flow side walls extending inwards from the inner side wall of the reflector and a connecting side wall connected between the two turbulent flow side walls, so that the cross section of the secondary flow guide surface is U-shaped.

The cross section of the auxiliary guide surface, namely the cross section of the turbulence protrusion, is U-shaped, and the turbulence protrusion extends downwards from the top wall of the reflector to the edge of the inner side wall of the reflector, so that the structure of a drawing die for manufacturing the reflector is simplified, and demolding after drawing forming is facilitated.

Particularly, the auxiliary guide surface comprises two turbulence side walls with different directions and a connecting side wall connected between the turbulence side walls, so that when high-speed airflow formed by the centrifugal fan blows to the turbulence protrusions, reflected airflow with different reflection directions and distances can be formed, sufficient turbulence is further formed with the high-speed airflow sent out in the radial direction, the area of downward high-temperature airflow is favorably diffused as much as possible, and food materials on the grill are heated uniformly as much as possible.

Preferably, the electric heating element is an electric heating pipe arranged below the centrifugal fan.

In the scheme, the electric heating element is arranged below the centrifugal fan, so that high-speed airflow sent by the centrifugal fan cannot be blocked by the electric heating element before forming turbulent flow with the airflow reflected by the turbulent flow protrusions, and the turbulent flow degree of the two airflows is favorably enhanced. It can be understood that the electric heating elements can be distributed in the lower space of the centrifugal fan as much as possible, so as to heat the downward turbulent flow uniformly and effectively. Because the air flow blown onto the reflecting cover is not heated by the electric heating element, and only the downward high-speed air flow can be heated by the electric heating element to be heated, the heat generated by the electric heating element can be completely used for heating the air flow and baking food materials, and meanwhile, the temperature rise of the reflecting cover can be effectively reduced, and the heat efficiency of the electric heating element is further improved.

Preferably, the electric heating element is an electric heating pipe which is positioned between the centrifugal fan and the inner side wall of the reflector and surrounds the centrifugal fan.

In the scheme, the electric heating element can be made into a circular ring shape, so that the structure of the electric heating element is simplified, and the electric heating element is convenient to process and manufacture. In addition, the electric heating element is arranged between the centrifugal fan and the inner side wall of the reflecting cover and surrounds the centrifugal fan, namely, the electric heating element can be arranged higher than the lower side of the centrifugal fan. Therefore, when the upper cover is turned over and opened, the high-temperature electric heating element cannot be directly exposed, and scalding accidents caused by mistaken touch of the electric heating element by a user can be effectively avoided.

Preferably, the distance between the turbulence protrusion and the centrifugal fan is A, and A is more than or equal to 1mm and less than or equal to 30 mm. Further, the distance A between the turbulence protrusion and the centrifugal fan can be controlled in the following range: a is more than or equal to 3mm and less than or equal to 5 mm.

It will be appreciated that the airflow from the centrifugal fan will have a divergence, that is, as the distance increases, the area over which it is blown will gradually increase and the flow rate will decrease. Therefore, by reasonably controlling the distance A between the turbulence protrusion and the centrifugal fan, the flow velocity of the air flow which enters the inner pot downwards after being guided by the main guide surface and the auxiliary guide surface of the reflector can be ensured, and the mutual collision of the turning air flow guided by the main guide surface and the auxiliary guide surface to form sufficient turbulence is facilitated. Particularly, in a certain reflector space, the size of the centrifugal fan can be increased as much as possible, and the air output is increased. When A is less than 1mm, the blade of the centrifugal fan is easy to generate friction interference with the turbulence protrusion due to an excessively small distance. When A is more than 30mm, the excessive distance is not beneficial to increasing the size of the centrifugal fan and the air output.

Preferably, 2-4 turbulence protrusions uniformly arranged in the circumferential direction are arranged on the inner side wall of the reflector.

Through rationally setting up the bellied quantity of vortex, both can realize abundant turbulent flow, and then promote the homogeneity of interior pot baking temperature, can reduce the windage that the air current bore again as far as possible. When the number of the turbulence protrusions is less than 2, the turbulence effect of the airflow is affected, and then the uniformity of the baking temperature of the inner pot is affected. When the number of the turbulence protrusions is more than 4, the air resistance of the air flow blown out by the centrifugal fan is too large, so that the flow velocity of the air flow is reduced, and the efficiency of the centrifugal fan is influenced.

Preferably, an included angle is formed between the turbulent flow side wall and the radial direction of the reflector, so that the inner end part of the turbulent flow protrusion, which is far away from the inner side wall of the reflector, is smaller than the root part of the connecting inner side wall.

Because the inner end part of the turbulence protrusion far away from the inner side wall of the reflecting cover is smaller than the root part of the connecting inner side wall, the cross section of the turbulence protrusion is approximately V-shaped, and demoulding after the forming of the reflecting cover is facilitated, so that the processing and the manufacturing are facilitated. Meanwhile, an included angle is formed between the airflow blown out by the centrifugal fan and the turbulence side wall, namely, the turbulence side wall can guide and turn the airflow to form a sufficient turbulence effect.

Preferably, in the rotation direction of the centrifugal fan, an included angle between the turbulent flow side wall located on the rear side of the auxiliary guide surface and the radial direction of the reflector is α, an included angle between the turbulent flow side wall located on the front side and the radial direction of the reflector is β, and α > β.

When the centrifugal fan is operated, the air flow of the centrifugal fan is firstly driven by the centrifugal fan to rotate at a high speed and then flows out radially at a high speed. That is, the airflow generated by the centrifugal fan will rotate in the same direction as the centrifugal fan in the reflection housing. Thus, the airflow at the rear side of the turbulence protrusion first flows forward along the side wall of the reflector to flow through the turbulence protrusion. When the included angle alpha between the turbulent flow side wall of the auxiliary flow guide surface positioned at the rear side and the radial direction of the reflecting cover is larger than the included angle beta between the turbulent flow side wall positioned at the front side and the radial direction of the reflecting cover, when the rotating airflow guided by the side wall of the reflecting cover meets the turbulent flow side wall of the auxiliary flow guide surface positioned at the rear side, the resistance can be obviously reduced, the turbulent flow side wall can form larger centripetal reaction force on the airflow, and the airflow further forms an enough turbulent flow effect. On the contrary, the turbulent side wall positioned at the front side directly guides the airflow blown out by the centrifugal fan to flow onto the side wall of the reflector, so that the wind resistance can be reduced to the maximum extent by the smaller included angle beta.

Therefore, the utility model discloses following beneficial effect has: the food material baking device is beneficial to baking the food material on the grill at uniform temperature, so that the food material can be cooked synchronously, the taste of processed food material is improved, the structure is simple, and the processing and manufacturing are convenient.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1 and fig. 2, an air fryer with uniform baking temperature comprises a shell 1 positioned at the bottom, an inner pan component 2 arranged in the shell, and an upper cover component 3 arranged on the top surface of the shell and provided with a control key, wherein the inner pan component comprises an inner pan 21, and the upper cover component comprises an upper cover 31, a reflecting cover 32 arranged in the upper cover, an electric heating element 33 arranged in the reflecting cover, and a centrifugal fan 34 driven by a motor. The reflector includes a circular top wall, and an annular inner side wall extending downward from the edge of the top wall, so that the reflector is substantially in the shape of a shallow disk, and the inner side wall of the reflector constitutes a main flow surface 321 for allowing the airflow blown by the centrifugal fan to flow downward. In addition, set up at least one vortex arch 35 on the inside wall of bowl, vortex arch includes the vice water conservancy diversion face 351 that makes the air current that centrifugal fan blew off flow downwards.

When the electric heating element and the centrifugal fan are started, the electric heating element heats the high-speed airflow blown out by the centrifugal fan, the top wall of the reflecting cover can guide the high-speed airflow blown out by the centrifugal fan to the inner side wall, and a part of the high-speed airflow is changed into baking hot air which is downwards turned to enter the inner pot through the guiding effect of the main airflow surface formed by the inner side wall of the reflecting cover. The top wall of the reflecting cover can also effectively reflect upward heat radiation generated by the electric heating element to enable the electric heating element to heat high-speed airflow downwards, so that the heat efficiency of the electric heating element is improved. The other part of high-speed airflow blown out by the centrifugal fan is guided by the auxiliary flow guide surface on the flow disturbing bulge to enter the inner pot downwards.

It can be understood that, because the distance between the secondary flow guide surface and the center of the grill is inconsistent, and the orientation between the primary flow guide surface and the secondary flow guide surface is inconsistent, the primary hot air with a larger range can be formed on the grill by the air flows guided by the secondary flow guide surface and the primary flow guide surface, and the food materials on the grill can be uniformly baked.

In addition, when the high-speed airflow sent by the centrifugal fan blows the reflecting cover, the turbulence protrusions can form a strong turbulence effect on the high-speed airflow, at the moment, the airflow entering the inner pot downwards is in a turbulent state, and when the airflow reaches the food material on the grill downwards, the airflow can be diffused due to the turbulence effect, so that high-temperature primary hot air can basically act on the food materials of the whole grill, and the uniformity of cooking of the food materials can be ensured.

Certainly, the inner side wall is provided with a certain demoulding inclination, so that the drawing forming is facilitated, and the wind resistance of high-speed airflow can be reduced as much as possible.

The dish-shaped reflector is preferably made of stainless steel sheet material by a sheet metal process such as stamping and drawing to withstand the high temperatures of the heating elements. In addition, the turbulence protrusions extend downwards from the top wall of the reflecting cover to the edge of the inner side wall, and at the moment, the circumferential side face, connected with the inner side wall of the reflecting cover, on the turbulence protrusions form the auxiliary flow guide face.

Further, the secondary flow guide surface of the turbulent flow protrusion comprises two turbulent flow side walls 352 extending inwards from the inner side wall of the reflector and a connecting side wall 353 connected between the two turbulent flow side walls, that is, the cross section of the secondary flow guide surface is in a U shape. On one hand, the structure of a drawing die for manufacturing the reflector is simplified, and the demolding after drawing forming is facilitated. On the other hand, the secondary flow guide surface at this moment comprises two turbulence side walls with different orientations and a connecting side wall connected between the turbulence side walls, so that when high-speed airflow formed by the centrifugal fan blows to the turbulence protrusions, reflected airflow with different reflection directions and distances can be formed, sufficient turbulence is formed with the high-speed airflow sent out in the radial direction, the area of downward high-temperature airflow can be diffused as much as possible, and food materials on the grill can be heated uniformly as much as possible.

In addition, 2-4 turbulence protrusions can be arranged on the inner side wall of the reflecting cover, and the turbulence protrusions are uniformly distributed on the inner side wall in the circumferential direction, so that sufficient turbulence can be realized, the uniformity of the baking temperature of the inner pot is improved, and the wind resistance borne by airflow can be reduced as much as possible.

Furthermore, an included angle can be formed between the turbulence side wall and the radial direction of the reflecting cover, so that the inner end part of the turbulence protrusion, which is far away from the inner side wall of the reflecting cover, is smaller than the root part of the connecting inner side wall. That is to say, the distance between two bellied vortex lateral walls of vortex wants to take from the bowl inside wall and reduces gradually to make the bellied cross section of vortex roughly be the V-arrangement, and then the knockout of bowl after the panel beating shaping of being convenient for, in order to make things convenient for manufacturing.

It will be appreciated that when the centrifugal fan is in operation, its air flow is first driven by the centrifugal fan to rotate at a high speed and then to exit radially at a high speed. That is, the air flow blown out from the outer end of the blade of the centrifugal fan has a radial speed and a tangential speed, so as to form an inclined air flow having a certain included angle with the turbulent flow side wall, and the inclined air flow can form a rotation consistent with the rotation direction of the centrifugal fan under the guidance of the main flow surface of the reflector.

Therefore, as shown in fig. 3, in the rotation direction of the centrifugal fan, an included angle between the turbulent flow sidewall on the rear side in the auxiliary guide surface and the radial direction of the reflector is α, and an included angle between the turbulent flow sidewall on the front side and the radial direction of the reflector is β, so that the included angle α between the turbulent flow sidewall on the rear side in the auxiliary guide surface and the radial direction of the reflector can be properly increased, the included angle β between the turbulent flow sidewall on the front side and the radial direction of the reflector can be properly decreased, and then the two included angles are controlled to be α > β.

Therefore, when the centrifugal fan works, the rotating airflow formed under the guidance of the main airflow surface can be separated by the turbulence protrusions, and the airflow positioned on the rear side of the turbulence protrusions firstly flows forwards along the inner side wall of the reflector and flows through the turbulence protrusions. When the included angle alpha between the turbulent flow side wall of the rear side of the auxiliary flow guide surface and the radial direction of the reflector is large, the resistance can be remarkably reduced when the rotating airflow guided by the main flow guide surface of the reflector meets the turbulent flow side wall of the rear side of the auxiliary flow guide surface, and the turbulent flow side wall can form large centripetal reaction force on the airflow so as to enable the airflow to form a sufficient turbulent flow effect. The turbulent side wall positioned on the front side directly guides the airflow blown out by the centrifugal fan to flow onto the main flow guide surface of the reflector, so that the wind resistance can be reduced to the maximum extent by the smaller included angle beta.

For convenient processing, the electric heating element can adopt an electric heating tube. As a preferred option, we can place the electrical heating element below the centrifugal fan as shown in fig. 1. Thus, when the high-speed airflow sent by the centrifugal fan is guided by the main guide surface and the auxiliary guide surface to form turbulent flow and then flows to the inner pot below, the high-speed airflow is heated by the electric heating element below to form high-temperature hot air. That is, the high-speed airflow from the centrifugal fan is not blocked by the electric heating element before being guided by the main flow guide surface and the auxiliary flow guide surface and forming turbulent flow, thereby being beneficial to enhancing the turbulent flow degree of the two airflows. It will be appreciated that the electrical heating tube supports the mosquito coil to fill the space below the centrifugal fan as much as possible, thereby facilitating even and effective heating of the downward turbulent flow.

In addition, when the high-speed airflow is blown onto the reflecting cover, the high-speed airflow is not heated by the electric heating element, and only the downward high-speed airflow is heated by the electric heating element, so that the heat generated by the electric heating element can be completely used for heating the airflow and baking food materials, the heating effect of the electric heating element on the reflecting cover is further reduced to the maximum extent, the heat efficiency of the electric heating element is improved, and the reflecting cover is convenient to keep at a stable temperature.

Further, as shown in fig. 3, the distance a between the spoiler protrusion and the centrifugal fan can be controlled to be in the following range: and A is more than or equal to 1mm and less than or equal to 30 mm. Preferably, the distance a between the disturbing protrusion and the centrifugal fan may be controlled in the following range: a is more than or equal to 3mm and less than or equal to 5 mm. The flow velocity of the air flow which enters the inner pot downwards after being guided by the main guide surface and the auxiliary guide surface of the reflector can be ensured, and the mutual collision of the turning air flow guided by the main guide surface and the auxiliary guide surface to form sufficient turbulence is facilitated. Particularly, in a certain reflector space, the size of the centrifugal fan can be increased as much as possible, and the air output is increased.

It should be noted that the distance a in this embodiment refers to the minimum distance between the outer circle and the spoiler protrusion when the blades of the centrifugal fan rotate.

As another preferred scheme, as shown in fig. 4, the electric heating element can be arranged in a ring shape, and the electric heating element is positioned in a gap between the centrifugal fan and the inner side wall of the reflecting cover. That is, the electric heating element at this time is disposed around the centrifugal fan, and the electric heating element may be disposed higher than the lower side of the centrifugal fan. Therefore, when people turn over upwards and open the upper cover, the high-temperature electric heating element cannot be directly exposed, and scalding accidents caused by mistaken touch of the electric heating element by users can be effectively avoided.

It is understood that various changes and modifications other than those described in the preferred embodiments described above may be made by those skilled in the art without departing from the spirit of the invention, and the scope of the invention is defined by the appended claims.
