Description

Technical Field

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

[0002] An air fryer is a kitchen appliance that uses hot air to fry food. Compared with deep-fried food, it contains less fat and is healthier.

[0003] The air fryer includes an outer shell, an inner pot and a frying basket. One side of the inner pot has an opening, and the frying basket enters and exits the inner pot through the opening. In order to obtain more cooking space, the hot air mechanism, power board and other components are usually arranged in the cavity at the top of the inner pot. When cooking, the hot air generated by the hot air mechanism blows toward the food in the frying basket for frying. During the frying process, the hot air not only heats the food in the frying basket, but also increases the wall temperature of the inner pot, thereby increasing the temperature of the cavity between the inner pot and the outer shell, causing the power board to rise too high, which can easily cause damage to the components on the power board. When the power of the hot air mechanism is large, the temperature rise in the cavity between the inner pot and the outer shell is more obvious, causing the surface temperature of the outer shell to be too high and hot to the touch. Summary of the invention

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0057] like Figure 1 to Figure 3As shown, this embodiment proposes an air fryer, which includes an outer shell 1, an inner liner 2, a frying basket 7 and a hot air mechanism. The inner liner 2 is arranged in the outer shell 1, and an entrance is correspondingly opened at the front end of the inner liner 2. The inner liner 2 includes a liner body 21 and a liner seat 22. The liner body 21 is a U-shaped frame. The liner seat 22 is installed in the outer shell 1. The liner body 21 is snap-fitted and installed on the liner seat 22 to form a frying pot cavity. The frying basket 7 extends into the frying pot cavity or is taken out of the frying pot cavity through the entrance. A handle 17 is installed on the outer shell 1, which is convenient for the user to take the air fryer by holding the handle 17; or the air fryer is hung at a designated position by the handle 17. The inner liner 2 divides the internal space of the outer shell 1 into an upper cavity and a lower cavity, and the display control panel 15 is installed in the upper cavity. When the power of the air fryer is high and the temperature in the upper cavity rises too high, a heat insulation cover 16 is installed on the display control board 15, and the display control board 15 is separated from the upper cavity by the heat insulation cover 16 to prevent the display control board 15 from rising too high and protect the safety of the display control board 15. The hot air mechanism is installed above the inner pot 2. When cooking, the hot air generated by the hot air mechanism is blown toward the food in the frying basket 7 for frying.

[0058] Specifically, Figure 2 As shown, the hot air mechanism includes a motor 41, a heat preservation chamber 43, a bracket 45 and a hot air fan blade 44. The motor 41 is fixedly mounted on the top wall of the inner pot 2 through the bracket 45, so that the motor 41 is reliably mounted. The heat preservation chamber 43 is arranged on the top wall of the inner pot 2 and is covered on the heating plate 8, and the heat preservation chamber 43 is connected with the inner pot 2. The hot air fan blade 44 is located in the heat preservation chamber 43 and directly above the heating plate 8. The heat preservation chamber 43 has a good heat insulation effect, which prevents the heat of the heating plate 8 from entering the cavity between the inner pot 2 and the outer shell 1. The output end of the motor 41 is connected to the hot air fan blade 44. The heating plate 8 generates heat after being energized. The motor 41 drives the hot air fan blade 44 to rotate, so as to blow the heat of the heating plate 8 into the inner pot 2, so as to fry the food in the frying basket 7 of the inner pot 2.

[0059] In existing air fryers, the hot air not only heats the food in the frying basket during frying, but also increases the wall temperature of the inner pot, causing the temperature in the upper cavity between the inner pot and the outer shell to rise, resulting in excessive temperature rise of the power board, which can easily damage the components on the power board. When the power of the hot air mechanism is large, the temperature rise in the upper cavity between the inner pot and the outer shell is more obvious, causing the surface temperature of the outer shell to be too high and hot.

[0060] To solve the above problems, Figure 2 and Figure 3As shown, the air fryer further includes a deflector 3 and a first fan assembly 4. The deflector 3 is disposed on the inner pot 2. A heat dissipation channel 30 is formed between the inner pot 2 and the deflector 3. The front end of the heat dissipation channel 30 is closed, and the rear end of the heat dissipation channel 30 is connected to the first heat dissipation hole 10 on the outer shell 1. At least part of the first fan assembly 4 is disposed in the heat dissipation channel 30, and can blow the heat in the heat dissipation channel 30 out of the outer shell 1 from the first heat dissipation hole 10. The deflector 3 is disposed on the inner pot 2 so that the heat dissipation channel 30 is formed between the inner pot 2 and the deflector 3. When the air fryer is frying food, the heat of the inner pot 2 after heating enters the heat dissipation channel 30, and is blown out of the outer shell 1 from the first heat dissipation hole 10 under the action of the first fan assembly 4, thereby improving the heat dissipation efficiency. The heat dissipation channel 30 plays a good role in heat insulation. The heat of the inner pot 2 after the temperature rises will not enter the cavity (i.e., the upper cavity) between the inner pot 2 and the outer shell 1, thereby preventing the electrical components installed in the cavity (mainly the electrical components on the power board 52) from being damaged due to excessive temperature rise, thereby improving the protection of the electrical components. At the same time, it also prevents the outer shell 1 from being too hot due to excessive temperature rise, thereby improving the safety of the air fryer.

[0061] In one embodiment, if Figure 3 and Figure 4 As shown, the first fan assembly 4 includes a driving member and a fan blade 42, the driving member is mounted on the top wall of the inner tank 2, and the fan blade 42 is located in the heat dissipation channel 30 and is drivingly connected to the output end of the motor 41. The driving member drives the fan blade 42 to rotate, so as to blow the heat (i.e., hot air) in the heat dissipation channel 30 out of the housing 1 through the first heat dissipation hole 10, thereby improving the heat dissipation efficiency of the heat dissipation channel 30 and preventing the temperature of the inner tank 2 from rising too high.

[0062] It should be noted that the driving part is the motor 41 of the hot air mechanism, and the output end of the motor 41 is coaxially connected with the guide fan blade 42 and the hot air fan blade 44. The first fan assembly 4 is assembled by adding the guide fan blade 42 to the hot air mechanism to make full use of the existing hot air assembly in the air fryer, simplify the structure, and realize the compact installation of the first fan assembly 4. Since the guide fan blade 42 and the hot air fan blade 44 are coaxially installed and share a motor 41, the guide fan blade 42 and the hot air fan blade 44 rotate synchronously. When the air fryer is heated and fried, the heat dissipation function is also realized synchronously, which reduces the control difficulty.

[0063] like Figure 5 and Figure 6As shown, the air deflector 3 includes a top plate 31 and two vertical plates 32. The top plate 31 is connected to the tops of the two vertical plates 32, so that the air deflector 3 is roughly U-shaped. The top plate 31 and the top wall of the inner tank 2 form an upper channel, and the two vertical plates 32 and the corresponding side walls of the inner tank 2 form side channels. The upper channel is connected to the two side channels to form a heat dissipation channel 30. The heat of the two side plates 11 of the inner tank 2 enters the corresponding side channels and rises to the upper channel (as shown in FIG. Figure 6 As shown by the arrow in the figure, the heat from the top wall of the inner tank 2 enters the upper channel and is discharged from the outer shell 1 through the first heat dissipation hole 10 under the action of the fan blades 42 (as shown in the figure). Figure 7 ).

[0064] Specifically, two vertical plates 32 are installed on the liner seat 22 of the liner 2, so that the air guide cover 3 is wrapped around the left and right sides and the top wall of the liner 2 to form a heat dissipation channel 30 with a U-shaped longitudinal section. A groove 120 is provided on the back plate 12 of the shell 1, and the rear end of the heat dissipation channel 30 abuts against the groove 120 to ensure the sealing between the heat dissipation channel 30 and the shell 1. A first heat dissipation hole 10 is opened in the groove 120, so that the heat of the heat dissipation channel 30 can be quickly discharged to the outside of the shell 1 through the first heat dissipation hole 10.

[0065] like Figure 5 and Figure 7 As shown, the front end of the top plate 31 is tilted downward and a reflector 311 is formed on the top of the front end of the heat dissipation channel 30 to reflect the hot air at the front end of the heat dissipation channel 30 to prevent the hot air from forming an air vortex at the front end of the heat dissipation channel 30, so that the heat can be smoothly discharged from the heat dissipation channel 30. The tilt angle of the reflector 311 can be flexibly adjusted according to the working conditions and is not specifically limited here.

[0066] In one embodiment, if Figure 5 As shown, a avoidance hole 312 is provided on the top plate 31, and at least part of the first fan assembly 4 passes through the avoidance hole 312. Specifically, the motor 41 of the first fan assembly 4 passes through the avoidance hole 312 after being installed in place, so as to avoid interference between the motor 41 and the air deflector 3. In order to prevent rainwater from splashing onto the motor 41, water baffles 33 extending in the left-right direction are provided on both sides of the avoidance hole 312 to improve the protection of the motor 41.

[0067] like Figure 5 As shown, the water baffle 33 includes a main plate 331 and a guide plate 332, and a main plate 331 is provided on both sides of the avoidance hole 312. The guide plate 332 is inclined from bottom to top toward the inner side of the air guide cover 3 at the top of the guide plate 332. The two guide plates 332 form an inverted V-shaped structure, which improves the shielding effect of rainwater and enhances the protection of the motor 41.

[0068] like Figure 7 As shown, the air fryer further includes a power board assembly 5, which is arranged on the inner side wall of the bottom plate 13 of the housing 1. Since the upper cavity has main heating elements (motor 41 and heating plate 8), which leads to a high temperature rise, the power board assembly 5 is installed in the lower cavity of the housing 1, so that the power board assembly 5 is away from the upper cavity with a high temperature rise, thereby avoiding damage to the power board assembly 5 due to excessive temperature rise, and improving the safety of the power board assembly 5.

[0069] like Figure 8 As shown, the power board assembly 5 includes a protection box 51, a power board 52 and a power line 53. The protection box 51 is arranged on the inner side wall of the bottom plate 13. The power board 52 is installed in the protection box 51. The protection box 51 has good insulation and waterproof effects, which improves the protection of the power board 52. One end of the power line 53 is electrically connected to the power board 52, and the other end of the power line 53 passes through the protection box 51 and the housing 1 to connect to the external power supply.

[0070] like Figure 8 and Fig. 9 As shown, a threading hole 510 is provided on the protection box 51, and the power cord 53 passes through the threading hole 510. In the up and down direction, the height of the power board 52 is greater than the height of the threading hole 510. Specifically, the protection box 51 includes a chassis 511 and an upper cover 512, and the upper cover 512 is buckled on the chassis 511. The power board 52 is installed on the chassis 511, and the side wall of the upper cover 512 is provided with a threading hole 510. Since the height of the power board 52 is greater than the height of the threading hole 510, the power cord 53 extends out of the threading hole 510 in a state of being tilted downward, thereby preventing rainwater in the lower cavity of the housing 1 from entering the power board 52 along the power cord 53, avoiding the dangers of short circuit, corrosion, etc. of the power board 52, and improving the safety of the power board 52.

[0071] like Fig.10 As shown, a drainage hole 130 is opened on the bottom plate 13 of the housing 1 to allow rainwater entering the lower cavity of the housing 1 to be quickly discharged, which not only prevents rainwater from accumulating on the bottom plate 13, but also prevents rainwater from entering the protective box 51 through the threading hole 510, further improving the protection of the power board 52.

[0072] In one embodiment, if Figure 7 and Fig.11 As shown, the inner bottom wall of the bottom plate 13 is further provided with a second fan assembly 6, which is located on one side of the power board assembly 5, and the portion of the housing 1 located below the inner tank 2 is provided with a first heat dissipation hole 10. The second fan assembly 6 increases the air convection intensity of the lower cavity of the housing 1, so as to cool the protection box 51 with air, prevent the power board 52 from overheating, and further improve the protection of the power board 52.

[0073] It should be noted that the air fryer of this embodiment can be used in indoor or outdoor environments. When the air fryer is used in outdoor environments, a plurality of second heat dissipation holes 140 with openings facing downward are provided on the side panels 11 and the back panel 12 of the housing 1. The heat inside the housing 1 can be discharged through the second heat dissipation holes 140, and the second heat dissipation holes 140 can also prevent outdoor rainwater from entering the housing 1, so as to meet the requirements of using the air fryer in outdoor environments.

[0074] Specifically, Fig.11 As shown, the housing 1 is provided with a plurality of waterproof cover plates 14 protruding outward, and the waterproof cover plates 14 are bent from top to bottom toward the inside of the housing 1. A plurality of second heat dissipation holes 140 distributed in an array are provided on the side plates 11 and the back plate 12 of the housing 1, so that a shutter structure is formed on the outer sides of the side plates 11 and the back plate 12, which increases the aesthetics. It should be noted that since the bottom of the back plate 12 is directly opposite to the lower cavity of the housing 1, it is not necessary to provide the second heat dissipation holes 140 at the bottom of the back plate 12, and it is only necessary to provide a plurality of first heat dissipation holes 10, so that the second fan assembly 6 can quickly discharge the heat emitted by the protection box 51 out of the housing 1 through the first heat dissipation holes 10, thereby simplifying the structure of the back plate 12.

[0075] In one embodiment, at least the top of the housing 1 has an anti-rust coating. When the air fryer is used in an outdoor environment, the anti-rust coating can not only prevent rainwater from corroding the housing 1, but also enhance the housing 1's ability to resist aging and UV radiation, so as to protect the appearance of the housing 1 and increase its service life. The material of the anti-rust coating can be flexibly adjusted according to demand, as long as it can ensure corrosion resistance, aging resistance, and UV radiation resistance, and is not specifically limited here.

[0076] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
