Description

Technical Field

[0001] The invention relates to the technical field of cooking appliances, and in particular to an air fryer. Background Art

[0002] In order to observe the cooking status of food during the cooking process, the air fryer in the related art usually has a visual window at the top front position of the air fryer. However, the setting of the visual window will cause the upper heating component to be placed at the rear. At this time, during the cooking process, the hot air generated by the upper heating component is not easy to reach the front area of ​​the cavity of the inner pot, which leads to poor cooking uniformity of food and easy to be undercooked. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

[0004] To this end, an embodiment of the present invention provides an air fryer, which has the advantages of good cooking uniformity of food and is less likely to cause undercooked food.

[0005] The air fryer of the embodiment of the present invention includes a shell, an upper heating assembly and a lower heating assembly, wherein the upper heating assembly and the lower heating assembly are respectively installed on the top and the bottom of the shell, and the shell, the upper heating assembly and the lower heating assembly surround a shaped cooking cavity, and a visual window is provided on the top of the shell, wherein the visual window is located beside the upper heating assembly and extends from the outer surface of the shell to the inner top wall surface of the cooking cavity, and on a projection plane perpendicular to the height direction of the shell, the center point of the projection of the lower heating assembly is located on the side of the projection of the center point of the projection of the bottom wall surface of the cooking cavity toward the visual window.

[0006] According to the air fryer of the embodiment of the present invention, by setting a visible window beside the upper heating component, the cooking cavity is divided into a first zone opposite to the upper heating component in the height direction of the shell and a second zone opposite to the visible window. At this time, the efficiency of the upper heating component in heating the first zone is higher than that of heating the second zone. On the projection plane perpendicular to the height direction of the shell, by setting the center point of the projection of the lower heating component to be located on the side of the projection of the center point of the projection of the bottom wall surface of the cooking cavity toward the visible window, the lower heating component is offset toward the second zone. At this time, the efficiency of the lower heating component in heating the second zone is higher than that of heating the first zone. Therefore, under the mutual cooperation of the upper heating component and the lower heating component, the heating speed of the first zone and the heating speed of the second zone can be made consistent. Therefore, while observing the state of the food in the cooking state through the visible window, the air fryer can effectively ensure the cooking uniformity of the food, and the probability of the food being undercooked is lower.

[0007] Optionally, on a projection plane perpendicular to the height direction of the shell, a distance between a center point of a projection of the lower heating assembly and a center point of a projection of a bottom wall surface of the cooking cavity is d, wherein 10 mm ≤ d ≤ 20 mm.

[0008] The air fryer in the embodiment of the present invention, by setting 10mm≤d≤20mm, can, on the one hand, avoid the offset distance of the lower heating component relative to the center of the cooking cavity being too small, resulting in the heating rate of the second zone being still significantly lower than the heating rate of the first zone; on the other hand, avoid the offset distance of the lower heating component relative to the center of the cooking cavity being too large, resulting in the heating rate of the second zone being significantly higher than the heating rate of the first zone, thereby better ensuring the cooking uniformity of food in the air fryer.

[0009] Optionally, the upper heating assembly includes a drive motor and a fan, the drive motor is mounted on the shell, the fan is coaxially connected to the rotating shaft of the drive motor, the fan is located on the side of the drive motor facing the cooking cavity, and the end of the fan adjacent to the cooking cavity is tilted toward the side close to the visible window.

[0010] The air fryer of the embodiment of the present invention is configured to be inclined toward the second zone by setting the driving motor and the fan. When the fan rotates under the drive of the driving motor, the hot air can be blown obliquely toward the second zone through the first zone, thereby making the efficiency of the upper heating component heating the first zone closer to the efficiency of heating the second zone. At this time, the lower heating component does not need to be offset too far to effectively ensure the uniformity of cooking of food in the air fryer.

[0011] Optionally, the shell includes a partition, the base of the drive motor is installed on the side of the partition facing away from the cooking cavity, the fan is located on the side of the partition facing the cooking cavity, the axial direction of the drive motor's shaft is perpendicular to the partition, and one end of the partition adjacent to the visible window is higher than the end of the partition away from the visible window.

[0012] The air fryer of the embodiment of the present invention can ensure the deflection angle of the drive motor and the fan by designing a partition at an angle to the horizontal angle on the shell, and the drive motor can be installed on the partition, and the installation efficiency of the upper heating component in the shell is high. In addition, the drive motor is installed on the side of the partition away from the fan and the cooking cavity, and the partition has a good protective effect on the drive motor, and the use performance and service life of the drive motor are higher.

[0013] Optionally, the partition forms an angle a with the height direction of the shell, wherein 82°≤a≤89°.

[0014] The air fryer in the embodiment of the present invention sets the angle between the partition and the shell in the height direction to be between 82° and 89°, that is, sets the fan deflection angle to be between 1° and 8°. On the one hand, it avoids the upper heating component from being deflected too much and occupying too much space in the horizontal direction of the shell to affect the size of the visual window. On the other hand, it avoids the upper heating component from being deflected too small and having no obvious effect on improving the heating efficiency of the second zone.

[0015] Optionally, the upper heating assembly further comprises an air guide hood connected to a side of the partition facing the cooking cavity, the air guide hood surrounds an air guide channel formed to communicate with the cooking cavity, the fan is located in the air guide channel, and the lower end of the air guide channel is tilted relative to the upper end toward a side close to the visual window.

[0016] In the air fryer of the embodiment of the present invention, the air guide channel also guides the flow direction of the hot air, and more reliably ensures that the hot air is blown toward the second zone, thereby better ensuring the uniformity of cooking food in the air fryer.

[0017] Optionally, the upper heating assembly further includes a first heating tube, which is connected to the air guide cover and is located on a side of the fan facing the cooking cavity.

[0018] The air fryer in the embodiment of the present invention arranges the first heating tube on the side of the fan facing the cooking cavity, and the wind blown by the fan passes through the first heating tube and enters the cooking cavity. In this process, the wind blown by the fan directly carries the heat on the first heating tube and enters the cooking cavity. The hot air outlet direction is stable and reliable, and the upper heating component has high cooking efficiency for food.

[0019] Optionally, the first heating pipe extends along the circumference of the fan, or the first heating pipe extends in a radial spiral around the central axis of the fan.

[0020] In the air fryer of the embodiment of the present invention, the axis of the first heating tube coincides with the axis of the fan, so that the flow direction of the hot air formed after the fan passes through the first heating tube is closer to the axial direction of the fan, thereby more reliably ensuring that the hot air enters the second zone and ensuring the uniformity of cooking of the food in the inner pot by the upper heating component.

[0021] Optionally, the lower heating assembly includes a heat conducting plate and a second heating tube, the heat conducting plate forms a portion of the bottom wall of the cooking cavity, and the second heating tube is installed on a side of the heat conducting plate away from the cooking cavity.

[0022] In the air fryer of the embodiment of the present invention, after the temperature of the second heating tube increases, the heat is transferred to the heat conducting plate, and the heat conducting plate transfers the heat to the inner pot in the cooking cavity, thereby heating the food. That is, the lower heating component heats the food in a heat conducting manner. The lower heating component has a simple structure and occupies little space in the shell.

[0023] Optionally, the shell includes a perspective panel, a window middle frame and a perspective plate which are connected in sequence, and the perspective panel, the window middle frame and the perspective plate together constitute the visible window, the perspective panel forms part of the outer wall surface of the shell, and the perspective plate forms part of the top wall surface of the cooking cavity.

[0024] In the air fryer of the embodiment of the present invention, the window middle frame can form a window through hole, and the perspective panel and the perspective plate respectively block the openings at both ends of the window through hole. The window middle frame ensures that the visual window is not blocked and prevents the user from seeing other components in the housing through the visual window. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0031] Combine the following Figure 1-Figure 3 An air fryer according to an embodiment of the present invention is described.

[0032] The air fryer of the embodiment of the present invention comprises a housing 1, an upper heating assembly 2 and a lower heating assembly 3. The upper heating assembly 2 and the lower heating assembly 3 are respectively installed on the top and the bottom of the housing 1. The housing 1, the upper heating assembly 2 and the lower heating assembly 3 surround a shaped cooking cavity. A visual window 11 is provided on the top of the housing 1. The visual window 11 is located beside the upper heating assembly 2 and extends from the outer surface of the housing 1 to the inner top wall of the cooking cavity. In the height direction perpendicular to the housing 1 ( Figure 1 On the projection surface (in the up and down direction), the center point of the projection of the lower heating assembly 3 is located on the side of the projection of the center point of the projection of the bottom wall surface of the cooking cavity toward the visible window 11.

[0033] According to the air fryer of the embodiment of the present invention, by setting a visible window 11 beside the upper heating assembly 2, the cooking cavity is divided into a first zone opposite to the upper heating assembly 2 in the height direction of the housing 1 and a second zone opposite to the visible window 11. At this time, the efficiency of the upper heating assembly 2 in heating the first zone is higher than that of heating the second zone. On the projection plane perpendicular to the height direction of the housing 1, by setting the center point of the projection of the lower heating assembly 3 to be located on the side of the projection of the center point of the projection of the bottom wall of the cooking cavity toward the visible window 11, the lower heating assembly 3 is offset toward the second zone. At this time, the efficiency of the lower heating assembly 3 in heating the second zone is higher than that of heating the first zone. Therefore, under the mutual cooperation of the upper heating assembly 2 and the lower heating assembly 3, the heating speed of the first zone and the heating speed of the second zone can be made consistent. Therefore, while observing the state of the food in the cooking state through the visible window 11, the air fryer can effectively ensure the cooking uniformity of the food, and the probability of the food being undercooked is lower.

[0034] It should be noted that Figure 2 As shown, the visual window 11 is located in front of the upper heating assembly 2, and the center of the lower heating assembly 3 is offset forward compared to the center of the cooking cavity. The first area is the rear area of ​​the cooking cavity, and the second area is the front area of ​​the cooking cavity.

[0035] In some embodiments, Figure 2 As shown, on the projection plane perpendicular to the height direction of the shell 1, the distance between the center point of the projection of the lower heating assembly 3 and the center point of the projection of the bottom wall of the cooking cavity is d, where 10mm≤d≤20mm.

[0036] By setting 10mm≤d≤20mm, on the one hand, it is avoided that the offset distance of the lower heating component 3 relative to the center of the cooking cavity is too small, resulting in the heating rate of the second zone being still significantly lower than the heating rate of the first zone; on the other hand, it is avoided that the offset distance of the lower heating component 3 relative to the center of the cooking cavity is too large, resulting in the heating rate of the second zone being significantly higher than the heating rate of the first zone, thereby better ensuring the cooking uniformity of food in the air fryer.

[0037] Specifically, on the projection plane perpendicular to the height direction of the housing 1 , the center point of the projection of the lower heating assembly 3 is offset forward by 10 mm, 15 mm and 20 mm compared to the center point of the projection of the bottom wall of the cooking cavity.

[0038] In some embodiments, Figure 2 and Figure 3 As shown, the upper heating assembly 2 includes a drive motor 21 and a fan 22. The drive motor 21 is installed on the shell 1. The fan 22 is coaxially connected to the rotating shaft of the drive motor 21. The fan 22 is located on the side of the drive motor 21 facing the cooking cavity. The end of the fan 22 adjacent to the cooking cavity is tilted toward the side close to the visual window 11.

[0039] By setting the driving motor 21 and the fan 22 to be tilted toward the second zone, when the fan 22 rotates under the drive of the driving motor 21, the hot air can be blown obliquely through the first zone to the second zone, thereby making the efficiency of the upper heating component 2 heating the first zone closer to the efficiency of heating the second zone. At this time, the lower heating component 3 does not need to be offset too far to effectively ensure the uniformity of the air fryer's cooking of food.

[0040] Specifically, on the basis that the viewing window 11 is located in front of the upper heating assembly 2, the lower end of the fan 22 is inclined obliquely downward and forward relative to the upper end.

[0041] In some embodiments, Figure 2 and Figure 3 As shown, the shell 1 includes a partition 12, the base of the driving motor 21 is installed on the side of the partition 12 facing away from the cooking cavity, the fan 22 is located on the side of the partition 12 facing the cooking cavity, the axial direction of the rotating shaft of the driving motor 21 is perpendicular to the partition 12, and the end of the partition 12 adjacent to the visible window 11 is higher than the end of the partition 12 away from the visible window 11.

[0042] By designing a partition 12 that is angled with the horizontal angle on the housing 1, the deflection angle of the drive motor 21 and the fan 22 can be ensured by installing the drive motor 21 on the partition 12, and the installation efficiency of the upper heating component 2 in the housing 1 is high. In addition, the drive motor 21 is installed on the side of the partition 12 away from the fan 22 and the cooking cavity, and the partition 12 has a good protective effect on the drive motor 21, and the use performance and service life of the drive motor 21 are higher.

[0043] Specifically, the thickness of each position of the partition 12 is consistent, the front end height of the partition 12 is higher than the rear end height of the partition 12, the drive motor 21 is installed above the partition 12, and the rotating shaft of the drive motor 21 passes through the partition 12 and is coaxially connected to the fan 22.

[0044] In some embodiments, the partition 12 forms an angle a with respect to the height direction of the housing 1 , wherein 82°≤a≤89°.

[0045] By setting the angle between the partition 12 and the shell 1 in the height direction between 82° and 89°, that is, setting the deflection angle of the fan 22 between 1° and 8°, on the one hand, it is avoided that the deflection angle of the upper heating component 2 is too large and occupies too much space in the horizontal direction of the shell 1 to affect the size of the visible window 11; on the other hand, it is avoided that the deflection angle of the upper heating component 2 is too small and the heating efficiency of the second zone is not significantly improved.

[0046] Specifically, the angle formed by the partition 12 and the height direction of the shell 1 can be 82°, 86° and 89°.

[0047] In some embodiments, Figure 2 and Figure 3 As shown, the upper heating assembly 2 also includes an air guide cover 23, which is connected to the side of the partition 12 facing the cooking cavity. The air guide cover 23 surrounds an air guide channel 231 formed to communicate with the cooking cavity. The fan 22 is located in the air guide channel 231, and the lower end of the air guide channel 231 is tilted toward the side close to the visual window 11 relative to the upper end.

[0048] The air guide channel 231 also guides the flow direction of the hot air, more reliably ensuring that the hot air is blown toward the second zone, thereby better ensuring the uniformity of cooking food in the air fryer.

[0049] Specifically, the air guiding channel 231 extends obliquely forward from top to bottom, and the cross-sectional area of ​​the air guiding channel 231 gradually increases from bottom to top, that is, the air guiding cover 23 is generally a bell-mouth structure with an open lower end.

[0050] It should be noted that a protective cover is also connected to the lower end of the air guide cover 23 , and the protective cover separates the air guide channel 231 from the cooking cavity, thereby preventing the user from contacting the first heating tube 24 and the fan 22 in the air guide channel 231 .

[0051] In some embodiments, the upper heating assembly 2 further includes a first heating tube 24 , which is connected to the air guide cover 23 and is located on a side of the fan 22 facing the cooking cavity.

[0052] By arranging the first heating tube 24 on the side of the fan 22 facing the cooking cavity, the wind blown by the fan 22 will pass through the first heating tube 24 and enter the cooking cavity. During this process, the wind blown by the fan 22 will directly carry the heat on the first heating tube 24 into the cooking cavity. The hot air outlet direction is stable and reliable, and the upper heating component 2 has a high cooking efficiency for food.

[0053] It should be noted that the first heating pipe 24 may also be disposed on the peripheral side of the fan 22 .

[0054] In some embodiments, the first heat pipe 24 extends along the circumference of the fan 22 , or the first heat pipe 24 extends spirally along the radial direction of the fan 22 around the central axis of the fan 22 .

[0055] The axis of the first heating tube 24 coincides with the axis of the fan 22 , so that the hot air flow direction formed after the fan 22 passes through the first heating tube 24 is closer to the axial direction of the fan 22 , thereby more reliably ensuring that the hot air enters the second zone and ensuring that the upper heating component 2 cooks the food in the inner pot 4 evenly.

[0056] Specifically, Figure 2 and Figure 3 As shown, the first heating tube 24 extends along the circumference of the fan 22 , and on a projection plane perpendicular to the axial direction of the fan 22 , the diameter of the circumscribed circle of the projected outer contour of the fan 22 is less than or equal to the inner diameter of the projected outer contour of the first heating tube 24 .

[0057] In some embodiments, the lower heating assembly 3 includes a heat conducting plate 31 and a second heating tube 32 , the heat conducting plate 31 forms part of the bottom wall of the cooking cavity, and the second heating tube 32 is installed on a side of the heat conducting plate 31 away from the cooking cavity.

[0058] After the temperature of the second heating tube 32 rises, the heat is transferred to the heat conducting plate 31, and the heat conducting plate 31 transfers the heat to the inner pot 4 in the cooking cavity, thereby heating the food. That is, the lower heating component 3 heats the food in a heat conduction manner. The lower heating component 3 has a simple structure and occupies a small space in the shell 1.

[0059] like Figure 2 and Figure 3 As shown, the housing 1 includes an inner tank bottom plate, the upper surface of the inner tank bottom plate is provided with a mounting groove, the heat conducting plate 31 is fitted in the mounting groove and connected to the inner tank bottom plate, and the second heating tube 32 is sandwiched between the heat conducting plate 31 and the bottom surface of the mounting groove. The heat conducting plate 31 is a circular plate, and the second heating tube 32 extends along the circumference of the heat conducting plate 31.

[0060] In some embodiments, the shell 1 includes a perspective panel 111, a window middle frame 112 and a perspective plate 113 connected in sequence, the perspective panel 111, the window middle frame 112 and the perspective plate 113 together constitute a visible window 11, the perspective panel 111 forms a portion of the outer wall surface of the shell 1, and the perspective plate 113 forms a portion of the top wall surface of the cooking cavity.

[0061] The window middle frame 112 can form a window through hole, and the perspective panel 111 and the perspective plate 113 respectively block the openings at both ends of the window through hole. The window middle frame 112 ensures that the visual window 11 is not blocked and prevents the user from seeing other components in the housing 1 through the visual window 11.

[0062] Specifically, Figure 2 and Figure 3As shown, the perspective plate 113 is made of transparent glass, the perspective panel 111 can be made of transparent plastic, the perspective plate 113 blocks the upper opening of the cooking cavity, and the perspective panel 111 forms part of the front side of the shell 1.
