Description

Technical Field

[0001] The present invention belongs to the technical field of air fryers, and particularly relates to a fry basket support assembly of an air fryer and an air fryer. Background Art

[0002] In the fry basket support assembly of a traditional air fryer, oil usually leaks through the support ventilation opening 41 in the support member 4, and the oil receiving side wall 521 of the oil receiving member 5 abuts against or is close to the outer edge of the support member 4, with no obvious gap therebetween; the oil cannot leak down from between the oil receiving side wall 521 and the support member 4.

[0003] The traditional fryer base 1 is provided with a heating device 18 and a blowing device 19. The blowing device 19 is usually a centrifugal fan. The air first flows along the rotation axis of the blowing device 19 and then away from the rotation axis of the blowing device 19. After the air flows away from the rotation axis of the blowing device 19, it flows upward through the ventilation gap E, and through the guidance of the fryer lid 2, the air flows inward and converges to flow downward, passes through the support ventilation opening 41, and is heated by the heating device 18; in this way, the air is gradually heated to form hot air, which heats the object to be heated (such as potatoes, chicken nuggets, etc.) placed in the fry basket 3 to achieve cooking.

[0004] However, in a traditional air fryer, since it is difficult for air to pass through the outer edge at the bottom end of the fry basket 3, the heating effect of the object to be heated at the outer edge at the bottom end of the fry basket 3 is poor compared with the heating effect of the object to be heated at the center of the fry basket 3; as a result, there are differences in the cooking effects of the objects to be heated in the fry basket 3. Summary of the Invention

[0005] The fry basket support assembly of the air fryer of the present invention is to provide an oil leakage path different from that of the fry basket support assembly of a traditional air fryer.

[0006] The means adopted by the fry basket support assembly of the air fryer of the present invention are as follows: The fry basket support assembly of the air fryer includes a support member provided with a support ventilation opening and an oil receiving member provided with an oil receiving ventilation opening; the support member is disposed on the oil receiving member; when viewed from above, the circumcircle of the support member is completely located within the oil receiving member to form an oil leakage cross-flow gap D.

[0007] A further technical solution is that the top surface of the support member is the highest point at the edge of the support ventilation opening and the lowest point at the outer edge of the support member.

[0008] The function achieved by the fry basket support assembly of the air fryer of the present invention is that since the top surface of the support member is an inclined surface with a lower outer edge, the oil dripping on the support member quickly flows by its own weight until it passes through the oil leakage cross-flow gap D and drips onto the oil receiving member.

[0009] The effects achieved by the fry basket support assembly of the air fryer of the present invention are as follows: it is possible to prevent oil droplets from falling on the fryer base and it is also convenient for cleaning.

[0010] In a further technical solution, from the cross-section of the support member 4, the connection line between the highest point and the lowest point is a straight line, a curve, an arc or a broken line.

[0011] In a further technical solution, the support member 4 is circular when viewed from above; the support ventilation opening 41 is circular when viewed from above and coincides with the center of the inscribed circle of the support member 4; the top end surface of the support member 4 is conical as a whole.

[0013] An air fryer includes the fry basket support assembly of the above-mentioned air fryer, and also includes a fryer lid, a fry basket, and a fryer base provided with a connecting portion; the fryer lid and the connecting portion enclose a fryer inner cavity, the fry basket is arranged in the fryer and is located above the support member, there is an overlapping part between the fry basket and the support member when viewed from above, the oil receiving member is kept in a relative position with the fryer base through the connecting portion; a ventilation gap E is provided between the oil receiving member and the fryer base so that air can pass through the outer wall of the oil receiving member; when viewed from above, the oil receiving ventilation opening is completely located between the support ventilation opening and the oil leakage cross-flow gap D; a cross-wind gap F is provided between the support member and the oil receiving member so that air can flow horizontally.

[0014] The functions achieved by the air fryer of the present invention are as follows: air can pass through the oil leakage cross-flow gap D and then can pass through the outer edge of the bottom end of the fry basket to heat the heated object.

[0015] The effects achieved by the air fryer of the present invention are as follows: it is possible to improve the heating effect on the heated object at the outer edge of the bottom end of the fry basket.

[0016] In a further technical solution, the oil receiving member further includes a baffle body that faces the support ventilation opening when viewed from above, and the baffle body is connected to the oil receiving member through at least one connecting body.

[0017] The baffle body can catch the oil dripping from the support ventilation opening to prevent the oil droplets from falling on the fryer base; at the same time, it is beneficial for air to pass through the oil leakage cross-flow gap D.

[0018] In a further technical solution, a plurality of load-bearing protrusions are formed by the convexity of the top end surface of the support member, so that a gap is formed between the top end surface of the support member and the bottom end surface of the fry basket.

[0019] It can ensure the oil leakage speed of the fry basket; the structure is simple and it is convenient for the removal and installation operation of the fry basket.

[0020] Further technical solution: The oil receiving part is fixedly provided with an oil receiving side wall, so that an oil receiving cavity is formed by enclosing the oil receiving part and the oil receiving side wall. At least two gap protrusions are formed by the outer wall of the support part extending outwards, and the gap protrusions are respectively attached to the oil receiving side wall.

[0021] It can ensure the ventilation gap E and at the same time the amount of oil that the oil receiving part can accommodate.

[0022] Further technical solution: The top surface of the support part extends upwards to form a fry basket limiting wall that abuts or is close to the outer wall of the fry basket.

[0023] So as to facilitate placing the fry basket in the required position.

[0024] Further technical solution: At least two gap protrusions are formed by the outer wall of the support part extending outwards, and the oil receiving side wall is provided with placing openings, and the gap protrusions are respectively embedded in the placing openings.

[0025] When the support part is placed on the oil receiving part, it is relatively stable and difficult to slide off, which is convenient for taking and placing the support part and the oil receiving part.

Detailed implementation manners

[0039] Next, the technical solutions of the present invention will be described in conjunction with the accompanying drawings of the embodiments of the present invention.

[0040] As a specific embodiment, the fry basket support assembly of the air fryer according to the embodiment of the present invention includes a support 4 provided with a support ventilation opening 41 and an oil receiving part 5 provided with an oil receiving ventilation opening 51; the support 4 is arranged on the oil receiving part 5.

[0041] The top surface of the support 4 is the highest point (height in terms of horizontal height) at the edge of the support ventilation opening 41 and the lowest point (height in terms of horizontal height) at the outer edge of the support 4. Preferably, from the cross-section of the support 4, the connection line between the highest point and the lowest point is a straight line, but it can also be a curve, an arc or a broken line, etc.

[0042] When viewed from above, the circumcircle of the support 4 is completely located within the oil receiving part 5 to form an oil leakage cross-flow gap D. It should be noted that the implementation manner in which the circumcircle of the support 4 is tangent to the inscribed circle of the oil receiving part 5 when viewed from above also belongs to the case where the circumcircle of the support 4 is completely located within the oil receiving part 5 when viewed from above.

[0043] Preferably, when viewed from above, the support 4 is circular; but when viewed from above, the support 4 can also be of other shapes, such as rectangular, pentagonal or hexagonal, etc. Generally, when viewed from above, the support ventilation opening 41 is circular and coincides with the center of the inscribed circle of the support 4; the overall top surface of the support 4 is conical.

[0044] As a specific embodiment, the air fryer according to the embodiment of the present invention further includes a fryer lid 2, a fryer basket 3, and a fryer base 1 provided with a connecting portion 11; the fryer lid 2 and the connecting portion 11 enclose a fryer inner cavity (not marked in the drawings, and the fryer inner cavity is usually a closed space), the fryer basket 3 is arranged inside the fryer and above the support member 4, and there is an overlapping part between the fryer basket 3 and the support member 4 when viewed from above, and the oil receiving member 5 is kept in a relative position with the fryer base 1 through the connecting portion 11.

[0045] Generally, the fryer basket 3 is cylindrical as a whole and placed on the support member 4, and is completely located inside the support member 4 when viewed from above. Of course, the fryer basket 3 can also be directly connected to the fryer lid 2 or the fryer base 1, such as by means of a suspension wire or the like.

[0046] Generally, the connecting portion 11 is a boss extending inward from the inner wall of the fryer base 1, and the oil receiving member 5 is placed on the connecting portion 11 so that the oil receiving member 5 is connected to the fryer base 1 through the connecting portion 11; of course, the connecting portion 11 can also be a tightening screw that abuts against the side wall of the oil receiving member 5, or other structures for maintaining the relative position between the oil receiving member 5 and the fryer base 1.

[0047] A ventilation gap E is provided between the oil receiving member 5 and the fryer base 1 so that air can pass through the outer wall of the oil receiving member 5.

[0048] Generally, the fryer base 1 is provided with a heating device 18 and a blowing device 19. The blowing device 19 is usually a centrifugal fan, so that air first flows along the rotation axis of the blowing device 19 and then away from the rotation axis of the blowing device 19.

[0049] Generally, after the air flows away from the rotation axis of the blowing device 19, it flows upward through the ventilation gap E, and through the guidance of the fryer lid 2, the air flows inward and converges to flow downward, passes through the support ventilation opening 41 and then is heated by the heating device 18; in this way, the air is gradually heated to form hot air (usually the air temperature is 100 - 500 °C, and usually can be stabilized at the air temperature of 200 - 300 °C), and the object to be heated (such as potatoes, chicken nuggets, etc.) placed in the fryer basket 3 is heated to achieve cooking.

[0050] When viewed from above, the oil receiving vent 51 is completely located between the support vent 41 and the oil leakage cross-flow gap D, so that there is no overlapping part between the oil receiving vent 51 and the support vent 41 and the oil leakage cross-flow gap D when viewed from above. Preferably, the oil receiving member 5 further includes a fluid blocking body 54 facing the support vent 41 when viewed from above. The fluid blocking body 54 is connected to the oil receiving member 5 through at least one connecting body 541, so that the oil receiving vent 51 is completely located between the support vent 41 and the oil leakage cross-flow gap D when viewed from above. The fluid blocking body 54 can catch the oil dripping from the support vent 41 and prevent the oil droplets from falling on the fryer base 1; at the same time, the air passing through the support vent 41 can also flow horizontally under the action of the fluid blocking body 54, converge with the horizontally flowing air flowing in from the oil leakage cross-flow gap D, and then pass through the oil receiving vent 51, which is beneficial to the air passing through the oil leakage cross-flow gap D (the air passing through the support vent 41 and flowing horizontally under the action of the fluid blocking body 54 can play a role similar to that of a baffle).

[0051] A horizontal wind gap F is provided between the support member 4 and the oil receiving member 5 to enable the air to flow horizontally. The horizontal flow is usually the air flowing along the horizontal plane, or the air flowing along a plane with an acute angle between the plane and the water surface.

[0052] The working principle is as follows Figure 7 As shown in the figure, the oil (not shown in the attached drawing) generated by heating the object to be heated passes through the frying basket 3 and drips on the support member 4 under the action of its own weight. Since the top surface of the support member 4 is an inclined surface with a lower outer edge, the oil dripping on the support member quickly flows under its own weight until it passes through the oil leakage cross-flow gap D and drips on the oil receiving member 5, preventing the oil droplets from falling on the fryer base 1. After heating the object to be heated is completed, after the support member 4 and the oil receiving member 5 are taken out of the fryer base 1 together, the oil on the oil receiving member 5 can be cleaned. Usually, the support member 4 and the oil receiving member 5 are detachably connected, and the support member 4 can be detached from the oil receiving member 5 for easy cleaning.

[0053] As Figure 6 shown, when the air flows upward through the ventilation gap E and is guided by the fryer lid 2 to flow inward, part of the air flows to the oil leakage cross-flow gap D, passes through the oil leakage cross-flow gap D and flows horizontally, and then passes through the heating device 18 and the blowing device 19; and so on in a cycle. The air can pass through the oil leakage cross-flow gap D, so that it can pass through the outer edge of the bottom end of the frying basket 3 and heat the object to be heated, thereby improving the heating effect on the object to be heated at the outer edge of the bottom end of the frying basket 3.

[0054] Preferably, an oil receiving positioning body 58 extends outward from the outer wall of the oil receiving member 5. The oil receiving positioning body 58 fits with the inner wall of the fryer base 1 to realize the positioning between the oil receiving member 5 and the fryer base 1, which can ensure that the width of the ventilation gap E is relatively uniform when viewed from above, and make the heating effect on the object to be heated at the outer edge of the bottom end of the frying basket 3 relatively uniform.

[0055] Further, a plurality of load-bearing protrusions 44 are formed by the top end surface of the support member 4 protruding, so that a gap is formed between the top end surface of the support member 4 and the bottom end surface of the frying basket 3. The load-bearing protrusions 44 can be strip-shaped, cylindrical, or annular around the ventilation opening 41. Usually, at least one of the load-bearing protrusions 44 abuts against the bottom end surface of the frying basket 3. Oil can drip between the load-bearing protrusions 44, thereby ensuring the oil leakage speed of the frying basket 3; at the same time, there is no need to additionally provide a structure for maintaining the position of the frying basket 3, and the structure is simple and convenient for the taking and placing operations of the frying basket 3.

[0056] Further, an oil-receiving side wall 521 is fixedly arranged on the oil-receiving member 5, so that an oil-receiving cavity 52 is formed by the oil-receiving member 5 and the oil-receiving side wall 521 surrounding. At least two gap protrusions 42 are formed by the outer wall of the support member 4 extending outwards, and the gap protrusions 42 are respectively attached to the oil-receiving side wall 521. It can ensure the ventilation gap E and at the same time the amount of oil that the oil-receiving member 5 can accommodate.

[0057] Further, the top end surface of the support member 4 extends upwards to form a frying basket limiting wall 49 that abuts against or is close to the outer wall of the frying basket 3; so as to facilitate placing the frying basket 3 in the required position, that is, when viewed from above, the frying basket 3 is completely located inside the support member 4.

[0058] Further, at least two gap protrusions 42 are formed by the outer wall of the support member 4 extending outwards, and the oil-receiving side wall 521 is provided with placing openings 53, and the gap protrusions 42 are respectively embedded in the placing openings 53. When the support member 4 is placed on the oil-receiving member 5, it is relatively stable and difficult to slide off, facilitating the taking and placing of the support member 4 and the oil-receiving member 5.

[0059] It should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation on the protection scope of the present invention.
