Detailed Implementation

[0014] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Please refer to Figure 1-19 As shown, an air fryer with multiple independent air ducts for heat dissipation includes an air fryer body. The air fryer body includes a mounting bracket 1. The outer wall of the mounting bracket 1 has multiple spaced protrusions 2. Air intake is provided between two adjacent protrusions 2. The mounting bracket 1 also has a first area 3 for mounting a circuit board and a second area 4 for mounting a motor. The mounting bracket 1 also has a baffle 5. The baffle 5 extends from one side of the mounting bracket 1, then surrounds the outer edge of the first area 3, and extends to the other side of the mounting bracket 1 to form at least two air ducts. This application isolates the first area and the second area by using the baffle. Natural air enters from the gap between the two protrusions, and then enters the first area to dissipate heat on the circuit board and the second area to dissipate heat on the motor, respectively. Thus, the two air ducts work independently without interfering with each other, avoiding crosstalk.

[0016] A fixing device 31 for fixing the circuit board is provided below the first area 3. An air outlet 32 ​​is provided at the bottom of the fixing device 31. The circuit board is supported by the fixing device, and the heat is dissipated through the air outlet, so that the air can fully contact the circuit board components and carry away their heat.

[0017] This application isolates the first area and the second area by means of a baffle. Natural air enters from the gap between the two protrusions, and then enters the first area to dissipate heat on the circuit board and the second area to dissipate heat on the motor. Thus, the two air ducts work independently without interfering with each other and avoiding crosstalk. Secondly, the circuit board is supported by a fixing device, and then the circuit board is cooled through the air outlet, so that the air makes full contact with the circuit board components and carries away their heat. In this embodiment, a fixing part 33 is provided at the diagonal of the fixing device 31. The fixing part is fixed to the volute to complete the assembly of the circuit board.

[0018] In this embodiment, a support bracket 34 is provided on the outer side of the fixing device 31. The support bracket securely supports the structure on the volute, preventing loosening and gaps that could affect the heat dissipation effect.

[0019] In this embodiment, the second region 4 is located on the screen side and has at least one surrounding cavity 6. The surrounding cavity 6 has a through hole 7 that connects to the screen. The surrounding cavity receives natural wind from between the protrusions and dissipates heat to the screen through the through hole.

[0020] In this embodiment, an upper cover 8 is also included. The upper cover 8 is provided with multiple buckles 9, and the mounting bracket 1 is provided with multiple locking cavities 10 that cooperate with the buckles 9. The upper cover can be quickly disassembled and assembled, improving assembly efficiency. The upper cover also serves to isolate the two air ducts.

[0021] In this embodiment, the card cavity 10 is provided with a surrounding plate 11 to prevent air from escaping from the card cavity.

[0022] In this embodiment, the height of the surrounding plate 11 is the same as the height of the baffle 5.

[0023] In this embodiment, the baffle 5 is provided with an excessively inclined bend 12 on one side of the first region 3. Through the guiding effect, it helps to send natural wind to the heat-generating components of the circuit board, thereby achieving a stronger heat dissipation effect on the circuit board.

[0024] In this embodiment, the baffle 5 is provided with at least one recess 13 at the edge of the first region 3.

[0025] In this embodiment, a volute body is also included. The volute body includes a wind turbine cavity 100 for accommodating the wind turbine, and a discharge cavity 101 communicating with the wind turbine cavity 100. The inner diameter of the discharge cavity 101 gradually increases from the inside to the outside. The end face of the volute body is provided with a plurality of Archimedean spirals 102 with a winding design.

[0026] This application concentrates the heat of the motor in the impeller cavity. As the impeller rotates, the heat is discharged through the exhaust cavity by utilizing the shape of the cavity. Since the exhaust cavity is funnel-shaped and uses an Archimedean spiral structure, the discharge efficiency is higher.

[0027] In this embodiment, a cooling through hole 103 is provided on the end face of the volute body opposite to the motor coil. A sealing part 104 is provided on the end face of the volute body opposite to the cooling through hole 103. The sealing part closes two through holes at the front end of the volute surface near the exhaust port, and only the cooling through hole corresponding to the positive projection area of ​​the motor coil is opened. A rectangular hole is set for the coil. The air flows directly from the motor mounting area to the motor cooling channel. The ventilation channel only serves to cool the motor.

[0028] In this embodiment, the end face of the volute body is provided with a plurality of convection holes 105 for connecting to the circuit board box. These convection holes are connected to the air outlet of the circuit board box to form convection cooling.

[0029] In this embodiment, the volute body is provided with a through hole 106 through which the motor shaft passes, and fixing holes 107 for fixing the motor are provided on both sides of the through hole 106. The motor is mounted on the volute through the fixing holes, and the shaft passes through the through hole and is connected to the impeller. The impeller is located in the impeller cavity.

[0030] In this embodiment, the inner wall of the discharge chamber 101 is provided with a plurality of flow guide steps 108 with an arc or inclined surface design. The flow guide steps with an arc-shaped guide design are conducive to guiding the air out during heat dissipation.

[0031] In this embodiment, an extension 109 is provided at the connection between the impeller cavity 100 and the discharge cavity 101 to prevent convection from forming at this location, so that the wind power is discharged in one direction.

[0032] In this embodiment, the volute body is provided with a support frame 110 for supporting the power supply box.

[0033] In this embodiment, a cover is also included. The cover has a protrusion 200 and a sensor hole 201 for installing an NTC sensor is provided on one side of the cover. An air guide ramp 202 facing the sensor hole 201 is provided at the edge of the protrusion 200.

[0034] This application utilizes the principle that when the wind turbine rotates, the wind force carries heat outward, and the hot air is directed towards the temperature sensor through the guide slope, thereby enabling rapid response and detection with higher accuracy.

[0035] In this embodiment, the wind guide ramp 202 and the protrusion 200 are connected by a bending transition 203. The opening direction of the bending transition 203 is opposite to the sensor hole 201. The bending transition is bent and tilted. The bent part is conducive to guiding the air and blowing it directionally to the temperature sensor through one end, thereby increasing the wind speed, detection efficiency, and accuracy.

[0036] In this embodiment, the other side of the cover is provided with an exhaust port 204. The edge of the protrusion 200 near the exhaust port 204 is designed with a guide slope. When the fan rotates, the wind force is clockwise. It is first detected by the temperature sensor, and then concentrated at the exhaust port through the horn-shaped edge. This not only allows for rapid detection of the current temperature, but also for quick heat dissipation.

[0037] In the exhaust port structure, the cover is provided with a protrusion 200, and a sensor hole 201 for installing an NTC sensor is provided on one side of the cover. The edge of the protrusion 200 is provided with a guide slope 202 facing the sensor hole 201.

[0038] This application includes a steam vent 204 disposed on one side of the hood, and a grille 209 disposed inside the pot body opposite to the steam vent 204. The grille 209 has multiple outlets 210, and multiple upward-bent plates 211 are disposed inside the outlets 210. An inclined guide plate 205 is disposed on one side of the steam vent 204. This application provides a steam vent that occupies only one-third of its end face in the steam hood, which can achieve the effect of centralized discharge. At this time, the flow rate is higher and the discharge effect is higher. In addition, the grille is disposed opposite to the discharge. When the steam is discharged, it passes through the grille of multiple outlets, thereby achieving high discharge efficiency and a larger discharge area. The bent plates play a guiding role.

[0039] In this embodiment, the fence 209 is also provided with a partition plate 213 to form two air ducts. The upper air duct is for exhaust of the volute, and the lower air duct is for exhaust of the heating tube. They are independent of each other to avoid crosstalk.

[0040] In this embodiment, a guide plate 205 with an inclined design is provided on one side of the exhaust port 204. The airflow passes through the guide plate to the edge on the other side and then is discharged in a concentrated manner to avoid collision.

[0041] In this embodiment, the corners of the protrusion 200 are curved to facilitate wind guidance and change of direction.

[0042] In this embodiment, an arc-shaped guide transition 206 is provided between the edge of the protrusion 200 and the wind guide slope 202, which is conducive to the concentrated guidance of wind force.

[0043] In this embodiment, one side of the cover is provided with a heating coil through hole 207 for installing the heating coil, and the other side is provided with a mounting bracket 208 for fixing the heating coil. The terminals at the two ends of the heating coil are installed through the heating coil through hole to facilitate external wiring. The heating coil is then fixed by the mounting bracket provided on the other side of the cover.

[0044] In this embodiment, a panel body 300 is included. The upper and lower ends of the panel body 300 are respectively provided with a plurality of oppositely arranged first ventilation holes 301 and second ventilation holes 302. The end face of the panel body 300 extends with an isolation rib 303 for surrounding the middle part of the panel body 300 to form three heat dissipation channels.

[0045] This application provides two symmetrical isolation ribs on the front side of the frying basket panel, with the end faces of the isolation ribs extending all the way to the cover, thus forming three air ducts. One is the area between the left isolation rib and the left side of the frying basket panel, and the other is the area enclosed between the two isolation ribs, thus forming a convection zone for heat dissipation and cooling of the front cover. Finally, there is the area enclosed by the right isolation rib and the right side of the frying basket panel. The three areas dissipate heat through their respective first and second ventilation holes, and each works independently without affecting the others, resulting in better heat dissipation.

[0046] In this embodiment, the panel body 300 is provided with a bone position 304 connected to the isolation rib 303 at the lower center.

[0047] Specifically, a bent extension 305 is provided on one side of the bone position 304. The bent extension 305 has a notch for adjusting the position and volume of the air inlet, thereby creating a controllable front cover surface temperature.

[0048] In this embodiment, the inner side of the panel body 300 is bent into an arc shape towards the inner liner, which not only allows for a better match with the inner liner, but also provides more space on both sides to set more ventilation holes.

[0049] In this embodiment, the isolation rib 303 is provided with a plurality of reinforcing ribs 306 to improve its strength.

[0050] In this embodiment, a base plate body 400 is also included. The inner cavity of the base plate body 400 is provided with a plurality of first protruding ribs 401 arranged laterally. The base plate body 400 is also provided with a second protruding rib 402 arranged vertically through the plurality of first protruding ribs 401. The first protruding ribs 401 and the second protruding ribs 402 are spaced apart to form a plurality of independent heat dissipation areas. Each heat dissipation area is provided with an air inlet channel 403.

[0051] This application uses a first protruding rib and a second protruding rib to separate multiple independent heat dissipation areas, and then each area is provided with an air intake channel to dissipate heat from the component in that area, avoid heat crosstalk, and achieve better heat dissipation effect.

[0052] In this embodiment, the air inlet channel 403 is also provided with a protruding design and a semi-circular cross-section air guide 404 to change the air inlet direction, which can increase the flow rate to the plane of the area and further improve the heat dissipation effect.

[0053] In this embodiment, the air inlet channel 403 is parallel to the second protruding rib 402 and is located on the side closer to the area, which can completely blow air to dissipate heat from the area.

[0054] In this embodiment, a plurality of vertically arranged third protruding ribs 405 are provided between the outermost first protruding rib 401 and the outer wall of the base plate body 400, thereby creating a plurality of independent heat dissipation areas on the edge side of the base plate body 400. A plurality of air inlet channels 403 are also provided in the heat dissipation area, which can dissipate heat to different components in multiple areas and avoid heat crosstalk.

[0055] In this embodiment, the air inlet channel 403 at the edge of the base plate body 400 is parallel to the first protruding rib 401 and is close to the side of the area, so that the area can be completely cooled by blowing air.

[0056] In this embodiment, the wind turbine body 500 has multiple blades 501 on its outer periphery. The outer end of each blade 501 extends downward to a first vertical section 502, and a second vertical section 503 extends downward near the inner side. The height of the second vertical section 503 is lower than that of the first vertical section 502. The second vertical section 503 is inclined to the outside of the blade 501 and has an inclined section 504.

[0057] This application divides the vertically downward blade into two sections. The first section is a vertically downward blade that blows the wind outward when it is in operation. The upper half of the second section is a vertically downward blade, while the lower half is angled. The entire blade has a certain angle front and back. When it is in operation, the wind blows inward while also creating a certain wind pressure along the side blades, thereby increasing the wind speed.

[0058] In this embodiment, the angle between the plane where the inclined segment 504 is located and the plane where the first vertical segment 502 is located is 45 degrees, which is the best angle to generate wind pressure.

[0059] In this embodiment, a gap is left between the inclined section 504 and the first vertical section 502. When bending the inclined section, the strength is not high due to the existence of a certain gap, so as to make it easier to bend.

[0060] In this embodiment, the fence 209 is further provided with a bent guide plate 212 connected to the bent plate 211.

[0061] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
