Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a structure for the motor mounting support of an air fryer. Background Technology

[0002] An air fryer is a kitchen appliance that uses hot air for cooking, replacing the large amounts of oil used in traditional fryers. It employs advanced air circulation technology to rapidly circulate heated air around the food, while temperature sensors and smart control chips precisely control cooking temperature and time. Users can select the appropriate temperature and time based on the different needs of the ingredients, and the cooking process is completed automatically for efficient cooking results.

[0003] Existing air fryers have the following drawbacks: 1. The structure of the motor mounting section for installing the drive motor is not reasonably designed, resulting in the drive motor being unstable and unreliable after installation; and the structure of the drive motor mounting section is not compact enough, resulting in a large vertical dimension, which affects the overall layout space; 2. Due to space limitations, it is inconvenient to install and lay out the circuit structure.

[0004] Therefore, how to design a motor mounting support structure for an air fryer with a simpler and more compact layout and more stable and reliable installation has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to design a motor mounting support structure for an air fryer with a simpler and more compact layout and more stable and reliable installation.

[0006] To achieve the above objectives, this utility model provides a motor mounting support structure for an air fryer, including a support plate arranged inside a clearance opening in a mounting shell. The support plate has multiple outwardly extending connecting strips around its perimeter, and the outer ends of each connecting strip are connected and fixed to the outer edge of the clearance opening on the mounting shell via a connecting and fixing structure. A mounting block is mounted and fixed above the support plate via the mounting support structure, such that the support plate and the mounting block are arranged vertically at intervals to form a ventilation gap. The mounting block has a mounting hole in its center, allowing the drive motor to be mounted within the mounting hole. A limiting strip is mounted and fixed above the mounting block, and the center of the limiting strip and the center of the support plate each have a bearing mounting cavity for mounting bearings, such that both ends of the drive motor shaft are inserted into the bearings within the bearing mounting cavities.

[0007] In this structure, by setting a support plate, which is connected and fixed to the mounting shell by multiple connecting strips evenly distributed along the circumference, the installation of the support plate becomes more stable and reliable. By installing mounting blocks on the support plate, arranging the drive motor in the mounting holes of the mounting blocks, and then installing a fixing limit strip above the mounting blocks, the two ends of the drive motor shaft are respectively fixed in bearings on the support plate and the limit strip, making the entire drive motor installation more stable and reliable. Furthermore, the ventilation gap formed between the support plate and the mounting blocks is more conducive to air circulation and heat dissipation.

[0008] As an optimization, the connecting strips are three evenly distributed along the circumference, and the connecting strips are integrally formed with the support plate.

[0009] In this way, the number of connecting strips is designed more reasonably, and the connecting strips are integrally formed with the support plate, making the structural design simpler, the integrity better, and the structural strength improved.

[0010] As an optimization, the connecting strip includes an inclined section that is connected to and mounted on the support plate and is inclined outward and upward. A horizontal section is integrally formed at the outer end of the inclined section, and the outer ends of the horizontal sections are each connected to the mounting shell by a connecting and fixing structure.

[0011] In this way, the structural design of the connecting strip is simpler and more reasonable. By setting the inclined section and the horizontal section of the connecting strip, the bracket plate is arranged inside the clearance opening, making the overall structural design more reasonable and the vertical arrangement more compact.

[0012] As an optimization, the connection fixing structure includes a support boss on the mounting shell corresponding to the outer end of the horizontal section of the connecting strip. A connecting post is provided in the middle of the support boss and extends into the connecting hole at the outer end of the horizontal section of the connecting strip. A cylindrical connecting sleeve made of rubber is sleeved on the outside of the connecting post. The outer circumferential surfaces of the upper and lower ends of the connecting sleeve protrude outward to form pressure rings and are respectively supported on the upper and lower surfaces of the horizontal section of the connecting strip. Screw holes are provided on the connecting post for arranging clamping screws, so that the clamping screws can be clamped on the upper end surface of the connecting sleeve.

[0013] In this way, the connection and fixing structure has the characteristics of better connecting and fixing the connecting strip to the mounting shell, and also has the characteristics of buffering the drive motor, thus better avoiding the impact of the vibration generated by the drive motor on the mounting shell.

[0014] As an optimization, a first reinforcing ridge and a second reinforcing ridge with an annular structure are provided at the outer edge of the clearance opening on the upper surface of the mounting shell; a plurality of connecting ridges arranged in an array along the circumferential direction are provided between the first reinforcing ridge and the second reinforcing ridge; and the supporting boss is correspondingly arranged between the first reinforcing ridge and the second reinforcing ridge.

[0015] This makes the structural design of the mounting shell more reasonable and can improve the structural strength of the edge of the mounting shell's clearance opening.

[0016] As an optimization, the mounting support structure includes a pair of support columns mounted on the bracket plate. The upper end face of the support column has a protrusion, and the lower surface of the mounting block has a vertical hole corresponding to the support column, so that the protrusion can extend into and fit into the lower end of the vertical hole. Each end of the limiting strip has a screw hole for arranging fastening screws, and the fastening screw passes through the vertical hole of the mounting block and is threadedly connected to the threaded fixing hole of the protrusion.

[0017] In this way, the installation support structure design is simpler and more reasonable. With the support columns and fastening screws, the bracket plate, mounting block and limit strip can be better connected together, and the connection is more stable and reliable.

[0018] As an optimization, the limiting strip includes a middle section that is horizontally arranged. The two ends of the middle section are bent downwards at an angle to form a vertical section of the limiting strip. The lower ends of the vertical sections are bent outwards horizontally to form a connecting section of the limiting strip. The screw holes are provided on the connecting section of the limiting strip.

[0019] In this way, the structural design of the limit strip is simpler and more reasonable, making layout design easier.

[0020] Furthermore, the lower surface of the limiting strip connecting section is provided with a mating protrusion that inserts into the upper end of the vertical hole. This further improves the stability of the installation.

[0021] As an optimization, two support columns are provided on one side of the mounting shell, and a circuit board is installed between the two support columns; a driver is installed inside the circuit board; and limit blocks are provided at both ends of the mounting block corresponding to the two ends of the driver, such that the two inner sides of the limit blocks are respectively attached to and supported at both ends of the driver.

[0022] In this way, by designing support columns, it is easier to install and arrange circuit boards and drivers. Furthermore, by setting limit blocks extending outward from both ends of the mounting block to correspond to the ends of the drivers, the drivers can constrain the mounting blocks, better preventing the mounting blocks from shaking and improving the stability of the drive motor installation.

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments of an air fryer device using the structure of the present invention. It should be noted that in the description of the present invention, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific manner, and therefore should not be construed as a limitation of the present invention. The terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] like Figures 1 to 14 As shown, an air fryer device includes a shell cover 2, which is a flat rectangular box structure with an open bottom, located inside the upper part of the air fryer shell 1. A heating tube 3 is installed inside the shell cover. A first fan blade 4 is provided above the heating tube inside the shell cover. A mounting shell 5, which is a rectangular box structure with an open bottom, is provided above the shell cover. An installation space is formed between the top of the shell cover and the mounting shell, and a second fan blade 6 is arranged there. A drive motor 7 is installed on the mounting shell. The motor shaft of the drive motor extends vertically downward and passes through the clearance opening 8 of the mounting shell and the mounting through hole of the shell cover in sequence. The first fan blade and the second fan blade are each mounted on the motor shaft. A circulating air vent 9 is provided on the side wall of the shell cover, extending through its wall thickness. An air inlet and outlet vent 10 is provided on the side wall of the mounting shell, opposite to the circulating air vent, extending through its wall thickness. A through opening 11 is provided on the air fryer shell corresponding to the air inlet and outlet vents.

[0039] Furthermore, a circuit structure is mounted and arranged on the mounting housing; the circuit structure includes a circuit board and a driver.

[0040] In this way, the air fryer device described above uses the same drive motor to synchronously drive the first and second fan blades to rotate. The first fan blade allows external airflow to enter from the air inlet and outlet, be heated by the heating element, and then flow downwards. The second fan blade allows the airflow in the installation space to flow outwards through the air inlet and outlet and the through opening, completing airflow circulation with the outside, thereby achieving the effect of cooling the drive motor and the interior of the installation space. This reduces the impact of the heat generated by the heating element on the drive motor and the circuit structure, thus providing a better working environment for the drive motor and the circuit structure, reducing the probability of failure, and increasing service life.

[0041] In this specific embodiment, the circulating air vent and the air inlet / outlet are respectively located on the rear side of the cover and the mounting housing.

[0042] This arrangement makes the placement of the air vents and inlet / outlet more reasonable and safer in actual use; the through opening is located on the rear side of the air fryer's outer shell.

[0043] In this specific embodiment, the inner bottom surface of the shell protrudes upward to form an overall cylindrical mounting cavity 12, and the first fan blade is arranged in the mounting cavity.

[0044] In this way, by setting up the installation cavity, it is easier to arrange the first fan blade, and it can also guide the airflow generated by the first fan blade, and better drive the heat generated by the heating tube downward.

[0045] In this specific embodiment, the rear part of the inner circumferential surface of the mounting cavity is pulled back to form an air intake guide groove 13, and the outer end face of the air intake guide groove is flush with the rear side of the shell cover, and the circulating air vent is provided on the outer end face of the air intake guide groove.

[0046] In this way, by setting up an air intake guide groove, the airflow can enter better and be heated by the heating tube.

[0047] Furthermore, the width of the inner end of the air intake guide groove is set to be greater than the width of the outer end.

[0048] In this specific embodiment, the inner bottom surface of the mounting shell protrudes upward to form a mating cavity 14 with an overall cylindrical structure, and the second fan blade is arranged in the mating cavity accordingly; a circular opening is provided on the bottom surface of the mating cavity to form the clearance opening.

[0049] In this way, by setting up a matching cavity, it is easier to install and arrange the second blade.

[0050] In this specific embodiment, a mating groove 15 is formed by pulling back a local position on the rear side of the inner circumferential surface of the mating cavity, and an air inlet and outlet that penetrate the wall thickness of the mounting shell is provided on the outer end face of the mating groove.

[0051] In this way, by setting a matching groove, it can be matched with the air intake guide groove on the shell cover, and it is also more convenient to arrange the air inlet and outlet.

[0052] In this specific embodiment, an air inlet / outlet grille 16 is installed on the through opening. The air inlet / outlet grille includes a grille cylinder 17 arranged in a rectangular shape, with the inner end of the grille cylinder connected to the air inlet / outlet. A vertically arranged support strip 18 is provided in the middle position inside the grille cylinder. Multiple guide strips 19 are arranged vertically at intervals between the support strip and the inner sidewall of the grille cylinder, and the outer side of the guide strip is arranged inclined upward.

[0053] In this way, by setting up air inlet and outlet grilles, air circulation can be better facilitated. Furthermore, the direction of the guide strips ensures upward airflow, making the setup more rational.

[0054] In this specific embodiment, the first fan blade has a plurality of first fan blade plates 20 that extend horizontally outward and are arranged in an array along the circumferential direction, and each of the first fan blade plates is bent downward on one side to form a first fan blade 21.

[0055] In this way, the structural design of the first blade is simpler and more reasonable, which can better enable the airflow to flow downward.

[0056] Furthermore, the first blade has six blades. Reinforcing ribs are provided on the first blade plate.

[0057] In this specific embodiment, the second fan blade has multiple horizontally extending outward and arrayed along the circumferential direction second fan blade plates 22, and each of the second fan blade plates is bent upward on one side to form a second fan blade 23.

[0058] In this way, the structural design of the second blade is simpler and more reasonable, which can better enable the airflow to flow upward.

[0059] Furthermore, the second blade has seven blades. Reinforcing ribs are provided on the second blade plate.

[0060] In this specific embodiment, a partition sleeve 24 is sleeved and fixed on the motor shaft of the drive motor, such that the upper and lower ends of the partition sleeve abut and support the second fan blade and the first fan blade respectively; and the partition sleeve is installed in the mounting through hole.

[0061] In this way, by setting up the separator sleeve, the vertical spacing between the first and second blades after installation can be made more stable.

[0062] like Figures 7 to 14 As shown; in this specific embodiment, a motor mounting support structure for an air fryer is also disclosed, including a support plate 26 arranged inside a clearance opening in the mounting shell, a plurality of outwardly extending connecting strips 27 around the support plate, and the outer ends of the connecting strips are each connected and fixed to the outer edge of the clearance opening on the mounting shell through a connecting and fixing structure; a mounting block 28 is mounted and fixed above the support plate through the mounting support structure, such that the support plate and the mounting block are arranged vertically at intervals to form a ventilation gap 29; the mounting block has an assembly hole in the middle, and the drive motor is mounted and arranged in the assembly hole; a limiting strip 30 is mounted and fixed above the mounting block, and the middle of the limiting strip and the middle of the support plate each have a bearing mounting cavity 31 for mounting and arranging bearings, such that the two ends of the motor shaft of the drive motor are respectively inserted and installed in the bearings in the bearing mounting cavity.

[0063] In this structure, by setting a support plate, which is connected and fixed to the mounting shell by multiple connecting strips evenly distributed along the circumference, the installation of the support plate becomes more stable and reliable. By installing mounting blocks on the support plate, arranging the drive motor in the mounting holes of the mounting blocks, and then installing a fixing limit strip above the mounting blocks, the two ends of the drive motor shaft are respectively fixed in bearings on the support plate and the limit strip, making the entire drive motor installation more stable and reliable. Furthermore, the ventilation gap formed between the support plate and the mounting blocks is more conducive to air circulation and heat dissipation.

[0064] Specifically, the connecting strip consists of three strips evenly distributed along the circumference, and the connecting strips are integrally formed with the support plate.

[0065] In this way, the number of connecting strips is designed more reasonably, and the connecting strips are integrally formed with the support plate, making the structural design simpler, the integrity better, and the structural strength improved.

[0066] Specifically, the connecting strip includes an inclined section 32 that is connected to and mounted on the bracket plate and is inclined outward and upward. A horizontal section 33 is integrally formed at the outer end of the inclined section, and the outer ends of the horizontal sections are each connected to the mounting shell through a connecting and fixing structure.

[0067] In this way, the structural design of the connecting strip is simpler and more reasonable. By setting the inclined section and the horizontal section of the connecting strip, the bracket plate is arranged inside the clearance opening, making the overall structural design more reasonable and the vertical arrangement more compact.

[0068] Specifically, the connection and fixing structure includes a support boss 34 on the mounting shell corresponding to the outer end of the horizontal section of the connecting strip. A connecting post 35 is provided in the middle of the support boss and extends into the connecting hole at the outer end of the horizontal section of the connecting strip. A connecting sleeve 36 made of rubber and designed in a cylindrical shape is sleeved on the outside of the connecting post. The outer peripheral surfaces of the upper and lower ends of the connecting sleeve protrude outward to form pressure rings and are respectively attached to and supported on the upper and lower surfaces of the horizontal section of the connecting strip. A screw hole 37 is provided on the connecting post for arranging clamping screws, so that the clamping screws can be clamped on the upper end surface of the connecting sleeve.

[0069] In this way, the connection and fixing structure has the characteristics of better connecting and fixing the connecting strip to the mounting shell, and also has the characteristics of buffering the drive motor, thus better avoiding the impact of the vibration generated by the drive motor on the mounting shell.

[0070] Specifically, a first reinforcing flange 38 and a second reinforcing flange 39 with an annular structure are provided on the outer edge of the clearance opening on the upper surface of the mounting shell; a plurality of connecting flanges are provided between the first reinforcing flange and the second reinforcing flange in an array along the circumferential direction; and the supporting boss is correspondingly arranged between the first reinforcing flange and the second reinforcing flange.

[0071] This makes the structural design of the mounting shell more reasonable and can improve the structural strength of the edge of the mounting shell's clearance opening.

[0072] Specifically, the mounting support structure includes a pair of support columns 40 mounted on the bracket plate. The upper end face of the support column has a protrusion 41, and each of the support columns has a vertical hole on the lower surface of the mounting block corresponding to the support column, so that the protrusion can be inserted into the lower end of the vertical hole. Each end of the limiting strip has a screw hole for arranging fastening screws, and the fastening screw passes through the vertical hole of the mounting block and is threadedly connected to the threaded fixing hole of the protrusion.

[0073] In this way, the installation support structure design is simpler and more reasonable. With the support columns and fastening screws, the bracket plate, mounting block and limit strip can be better connected together, and the connection is more stable and reliable.

[0074] Specifically, the limiting strip includes a middle section 42 that is horizontally arranged in the middle, two sections of the middle section of the limiting strip are bent downwards to form a vertical section 43 of the limiting strip, and the lower ends of the vertical sections of the limiting strip are bent outwards horizontally to form a connecting section 44 of the limiting strip. The screw holes are provided on the connecting section of the limiting strip.

[0075] In this way, the structural design of the limit strip is simpler and more reasonable, making layout design easier.

[0076] Furthermore, the lower surface of the limiting strip connecting section is provided with a mating protrusion 45, which is inserted into the upper end of the vertical hole. This further improves the stability of the installation.

[0077] Specifically, two support columns 46 are provided on one side of the mounting shell, and a circuit board 47 is installed between the two support columns; a driver 48 is installed inside the circuit board; and a limiting block 49 is provided at each end of the mounting block corresponding to the two ends of the driver, such that the two inner sides of the limiting block are respectively attached to and supported at the two ends of the driver.

[0078] In this way, by designing support columns, it is easier to install and arrange circuit boards and drivers. Furthermore, by setting limit blocks extending outward from both ends of the mounting block to correspond to the ends of the drivers, the drivers can constrain the mounting blocks, better preventing the mounting blocks from shaking and improving the stability of the drive motor installation.

[0079] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
