Detailed implementation manners

[0029] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0030] Below in conjunction with Figures 1-9 Describe the head assembly according to an embodiment of the present utility model.

[0031] The head assembly of the embodiment of the present utility model includes an outer shell 1, a heat insulation block 2 and a control box 3. The outer shell 1 surrounds to form an installation cavity. The heat insulation block 2 is connected to the outer shell 1. The control box 3 is located in the installation cavity, and the control box 3 is clamped between the heat insulation block 2 and the outer shell 1.

[0032] For the head assembly according to an embodiment of the present utility model, after the control box 3 is placed at a set position in the installation cavity of the outer shell 1, and the heat insulation block 2 is connected to the outer shell 1, the control box 3 can be clamped between the heat insulation block 2 and the outer shell 1, thereby realizing the fixed installation of the control box 3 in the installation cavity. At this time, the fixed installation of the control box 3 in the installation cavity does not require the use of fasteners, and at the same time, the heat insulation block 2 is also an original part of the air fryer. The head assembly does not need to additionally provide parts to replace the fasteners, thereby effectively reducing the number of parts of the head assembly, and the assembly process of the head assembly is simpler.

[0033] It should be noted that the control box 3 is the main electric control system of the air fryer, and is used to complete operations such as the selection of cooking food types and parameter adjustment of the air fryer under the control of the user. The heat insulation block 2 cooperates with the inner lining 4 of the air fryer. After the inner lining 4 is nested in the installation cavity of the outer shell 1, the heat insulation block 2 is located at the lower edge of the panel 11 of the outer shell 1 and is connected to the panel 11 through threaded parts.

[0034] In some embodiments, such as Figure 4 and Figure 6As shown, the housing 1 includes a panel 11. A first limiting rib 13 is provided on the inner surface of the panel 11. The control box 3 includes a light-shielding bracket 31. An avoidance groove 311 is provided on the side surface of the light-shielding bracket 31 facing the panel 11. The light-shielding bracket 31 abuts against the panel 11, and the first limiting rib 13 is fitted in the avoidance groove 311.

[0035] The cooperation between the first limiting rib 13 and the avoidance groove 311 can achieve the preliminary limiting of the light-shielding bracket 31 relative to the panel 11 in directions other than the thickness direction of the panel 11 when the light-shielding bracket 31 abuts against the inner surface of the panel 11, which is more convenient for adjusting the light-shielding bracket 31 to a set position so as to be reliably clamped and fixed between the heat insulation block 2 and the housing 1.

[0036] Exemplarily, the avoidance groove 311 is adjacent to the bottom surface of the light-shielding bracket 31. The avoidance groove 311 extends in the height direction. The width of the avoidance groove 311 is slightly larger than the width of the first limiting rib 13. The first limiting rib 13 is fitted in the avoidance groove 311, effectively realizing the relative fixation of the light-shielding bracket 31 and the panel 11 in the width direction of the avoidance groove 311.

[0037] In some embodiments, as Figure 5 、 Figure 6 and Figure 8 shown, the nose assembly further includes a limiting post 14 extending in the height direction. The upper end of the limiting post 14 is connected to the first limiting rib 13. The limiting post 14 is located below the first limiting rib 13 and is spaced apart from the panel 11. A limiting hole 312 communicating with the avoidance groove 311 is provided on the bottom surface of the light-shielding bracket 31. The limiting post 14 is fitted in the limiting hole 312.

[0038] The cooperation between the limiting hole 312 and the limiting post 14, combined with the fitting contact between the light-shielding bracket 31 and the inner surface of the panel 11, realizes the relative fixation of the light-shielding bracket 31 and the panel 11 in directions other than the height direction, further improving the fixed installation reliability of the light-shielding bracket 31 in the installation cavity.

[0039] Exemplarily, the dimension of the avoidance groove 311 in the height direction is larger than the overall dimension of the first limiting rib 13 and the limiting post 14 in the height direction. During specific assembly, first abut the light-shielding bracket 31 against the inner side surface of the panel 11 and make the first limiting rib 13 and the limiting post 14 as a whole fitted in the avoidance groove 311, and then move the light-shielding bracket 31 upward to complete the clearance fit between the limiting post 14 and the limiting hole 312.

[0040] In some embodiments, as Figure 3 shown, a threaded hole 141 is provided on the lower end surface of the limiting post 14. An installation hole 21 is provided on the heat insulation block 2. The heat insulation block 2 is connected to the limiting post 14 through a threaded member passing through the installation hole 21 and threadedly cooperating with the threaded hole 141.

[0041] That is, the heat insulation block 2 is connected to the limit post 14 through a threaded part, so as to realize the fixed installation of the heat insulation block 2 on the outer shell 1 and realize the clamping and fixing of the light shielding bracket 31 in the height direction. The assembly process of the heat insulation block 2 and the light shielding bracket 31 on the outer shell 1 is simple and the assembly efficiency is high.

[0042] Specifically, the threaded part is a bolt. After the light shielding bracket 31 and the heat insulation block 2 are sequentially placed at the set positions in the installation cavity, the bolt passes through the installation hole 21 from bottom to top and is in threaded fit with the threaded hole 141, so that the head of the bolt abuts against the bottom surface of the heat insulation block 2. Subsequently, by continuously rotating the bolt, the heat insulation block 2 and the light shielding bracket 31 can be driven to move upward synchronously until the light shielding bracket 31 abuts against the top plate 12 of the outer shell 1 or other components.

[0043] Optionally, as Figures 5-8 shown, there are at least two first limiting ribs 13, and all the first limiting ribs 13 are arranged at intervals along the first direction, and the first direction, the height direction and the thickness direction of the panel 11 are perpendicular to each other in pairs.

[0044] That is, at least two limit posts 14 cooperate with at least two limit holes 312 on the light shielding bracket 31, so that the light shielding bracket 31 is relatively fixed to the panel 11 in the thickness direction of the panel 11 at at least two positions, and further improves the limiting reliability of the light shielding bracket 31 in other directions except the height direction in the installation cavity.

[0045] Specifically, there are two first limiting ribs 13 arranged at intervals along the first direction, and the first direction is the width direction of the air fryer.

[0046] In some embodiments, as Figure 2 shown, the outer shell 1 further includes a top plate 12, and the light shielding bracket 31 is clamped between the heat insulation block 2 and the top plate 12.

[0047] During the process of connecting the heat insulation block 2 to the limit post 14 through the threaded part, the heat insulation block 2 gradually moves upward to push the light shielding bracket 31 towards the top plate 12 until the light shielding bracket 31 abuts against the top plate 12. At this time, the light shielding bracket 31 and the top plate 12 respectively limit the bottom surface and the top surface of the light shielding bracket 31, and the upper and lower parts of the light shielding bracket 31 are not easy to move away from the panel 11, and the fixed installation reliability of the light shielding bracket 31 in the installation cavity is higher.

[0048] Exemplarily, the top surface of the light shielding bracket 31 is in close contact with the bottom surface of the top plate 12.

[0049] In some embodiments, as Figure 2 shown, a second limiting rib 15 extends downward from the bottom surface of the top plate 12, and the second limiting rib 15 is spaced apart from the panel 11. At least part of the light shielding bracket 31 is limited between the panel 11 and the second limiting rib 15.

[0050] That is, the upper end of the shading bracket 31 is limited in the thickness direction of the panel 11 by the second limiting rib 15 and the panel 11, so that the upper end of the shading bracket 31 is more reliable in the installation cavity.

[0051] For example, before the limiting column 14 is engaged in the limiting hole 312 of the light shading bracket 31, the light shading bracket 31 is located below the second limiting rib 15. As the light shading bracket 31 moves upward to allow the limiting column 14 to pass through the limiting hole 312, at least a portion of the light shading bracket 31 gradually moves into the gap between the second limiting rib 15 and the panel 11 until the portion abuts against the top plate 12.

[0052] In some embodiments, as Figures 4-9 As shown, the upper surface of the shading bracket 31 is provided with a limiting groove 313 extending in the height direction. The limiting groove 313 is spaced apart from the side surface of the shading bracket 31 facing the panel 11 , and the second limiting rib 15 is fitted in the limiting groove 313 .

[0053] The second limiting rib 15 and the limiting groove 313 that cooperate with each other further ensure that the light shading bracket 31 and the shell 1 are relatively fixed in the width direction of the limiting groove 313. The upper end of the light shading bracket 31 is less likely to deviate and shake in its width direction, and the fixed installation reliability of the light shading bracket 31 in the installation cavity is higher.

[0054] For example, the width direction of the limiting groove 313 is consistent with the first direction, that is, consistent with the width direction of the air fryer, and the gap quota of the second limiting rib 15 is within the limiting groove 313.

[0055] like Figure 5 and Figure 9 As shown, the control box 3 also includes an electric control board 32 and a mica sheet 33. The side of the shading bracket 31 facing away from the panel 11 is provided with an accommodating cavity. The electric control board 32 is nested in the accommodating cavity. The mica sheet 33 is connected to the shading bracket 31 and closes the opening of the accommodating cavity.

[0056] That is, the electric control board 32 and the mica sheet 33 are both integrated and installed on the shading bracket 31. After the shading bracket 31 is installed in the installation cavity, the control box 3 is also installed in the installation cavity, and the assembly efficiency of the head assembly is higher.

[0057] For example, the electronic control board 32 is equipped with a digital tube for display and a display light for illuminating a partial light-transmitting area on the panel 11. The mica sheet 33 is clamped with the light-shielding bracket 31. It has good high-temperature insulation resistance and electrical insulation performance, and has a good protection effect on the electronic control board 32 in the accommodating cavity. The control box 3 is highly safe to use.
