[0036] The support frame 900 includes a disk body 910. A plurality of first guiding ribs 920 are provided on the upper end surface of the disk body 910 and are spaced circumferentially along the disk body 910. The first guiding ribs 920 extend radially along the disk body 910. The disk body 910 is higher in the middle and lower around, that is, the upper end surface of the disk body 910 has an upward slope α, which improves the hot air flow rate and guides the hot air to flow towards the bottom wall of the frying basket 600. The guiding ribs guide the hot air to flow towards the middle area 630 of the frying basket 600.

[0037] ​

[0038] In some specific embodiments of the present invention, referring to Figure 1 , a horizontal flanging 132 is formed by turning outwards the top of the heat-conducting chassis 130, and a vertical flanging 133 is formed by turning downwards the outer peripheral edge of the horizontal flanging 132. The inner peripheral surface of the bottom of the glass cylinder 110 has an annular flange 113. The vertical flanging 133 abuts against the upper end surface of the annular flange 113, and the side wall of the heat-conducting chassis 130 is in clearance fit with the central hole of the annular flange 113. During installation, first place the heat-conducting chassis 130 inside the glass cylinder 110, with the vertical flanging 133 abutting against the upper end surface of the annular flange 113, and then apply sealant to the gap between the outer surface of the heat-conducting chassis 130 and the glass cylinder 110 through the central hole of the annular flange 113 for sealing, so as to realize the sealed installation of the heat-conducting chassis 130 on the glass cylinder 110. The sealant is glass glue, with a simple structure and convenient installation.

[0039] In some specific embodiments of the present invention, referring to Figure 1 , two support members 140 are sleeved on the outer periphery of the heat-conducting chassis 130, and the corresponding ends of the two support members 140 are fixedly connected through threaded members (not shown in the figure), so that the two support members 140 clamp the heat-conducting chassis 130 tightly.

[0040] In some specific embodiments of the present invention, referring to Figure 3 , a plurality of second guiding ribs 930 are further provided on the upper end surface of the disk body 910 and are circumferentially and spaced apart along the circumference of the disk body 910. The second guiding ribs 930 extend radially along the disk body 910. The plurality of first guiding ribs 920 and the plurality of second guiding ribs 930 are alternately distributed circumferentially. The top of the outer end of the first guiding rib 920 protrudes upwards to form a hook 921 that is engaged and matched with the groove, realizing the quick installation and disassembly of the frying basket 600 and the support frame 900. The second guiding ribs 930 are added to increase the number of flow channels and reduce the width of the flow channels, so that the hot air at the bottom wall of the frying basket 600 is more uniform, thereby further improving the heating uniformity of the food materials.

[0041] In some specific embodiments of the present invention, referring to Figure 3 , the distance between the inner ends of the adjacent first guiding rib 920 and the second guiding rib 930 is A, and the distance between the outer ends is B, and A is less than B. The first guiding rib 920, the second guiding rib 930, the upper end surface of the disk body 910 and the bottom wall of the frying basket 600 together form a flow channel. Then the width of the inlet of the flow channel is B, and the width of the outlet of the flow channel is A. The width of the flow channel gradually becomes smaller along the flow direction, thereby accelerating the flow of the hot air and guiding the hot air to flow towards the middle area 630 of the frying basket 600.

[0042] In some specific embodiments of the present invention, referring to Figure 3, both the first guiding rib 920 and the second guiding rib 930 are arc-shaped, and the protruding directions of the arc shapes are the same, so as to increase the air volume passing through the bottom wall of the frying basket 600.

[0043] In some specific embodiments of the present invention, referring to Figure 3 , the inner end of the first guiding rib 920 is higher than the middle part of the first guiding rib 920, and the inner end of the first guiding rib 920 is lower than the hook 921; the inner end of the second guiding rib 930 and the outer end of the first guiding rib 920 are both higher than the middle part of the second guiding rib 930. In this way, there is a first gap 950 between the top surface of the first guiding rib 920 and the outer surface of the frying basket 600, and there is a second gap 960 between the second guiding rib 930 and the bottom wall of the frying basket 600. The first gap 950 and the second gap 960 communicate the adjacent two flow channels, so that the bottom wall of the frying basket 600 is heated evenly.

[0044] In some specific embodiments of the present invention, referring to Figure 3 , the disc body 910 is provided with a central hole corresponding to the middle area 630 of the frying basket 600. The inner end of the first guiding rib 92 is flush with the side wall of the central hole, and the outer end protrudes radially from the outer periphery of the disc body 910 by a certain distance C; the inner end of the second guiding rib 930 is flush with the side wall of the central hole, and the outer end protrudes radially from the outer periphery of the disc body 910 by a certain distance D, and D is less than C. Both the first guiding rib 920 and the second guiding rib 930 protrude from the outer periphery of the disc body 910 by a certain distance, so as to better guide the hot air into the flow channel.

[0045] In some specific embodiments of the present invention, referring to Figure 1 and Figures 3 - 4 , the lower end surface of the disc body 910 is provided with a plurality of support ribs 940 spaced circumferentially along the disc body 910 to prevent the support frame 900 from shaking under high-speed hot air.

[0046] In some specific embodiments of the present invention, referring to Figure 1 and Figures 3 - 4 , the inner end of the support rib 940 is flush with the side wall of the central hole, and the outer periphery of the disc body 910 protrudes radially from the outer end of the support rib 940 by a certain distance E, and E is greater than D. In this way, the outer periphery of the lower end surface of the disc body 910 contacts the upper end surface of the transverse flanging 132, so that the hot air can only flow upward on the upper end surface of the disc body 910, and the support rib 940 is located inside the side wall of the heat-conducting bottom plate 130.

[0047] In some specific embodiments of the present invention, referring to Figure 5 , the middle area 630 of the bottom wall of the frying basket 600 is higher than the peripheral area 640, and the connection between the middle area 630 and the peripheral area 640 is an inclined surface, which further guides the hot air to flow towards the middle area 630 of the bottom wall of the frying basket 600.
