Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] Reference Figure 1-6The heating assembly of this toaster is mounted above the base 100. The heating assembly includes an air guide shroud 300 and a heating plate 400 mounted on the air guide shroud 300. Adjacent heating assemblies form a heating groove 200, within which a bread tray (not shown) is provided. The heating groove 200 has vertically extending guide members 201 (e.g., guide rails or guide grooves) to guide the bread tray's vertical movement within the heating groove 200. Typically, in a toaster with two heating grooves 200, three of the above-mentioned heating assemblies are arranged side-by-side at intervals. Figure 1 Taking the heating plate 400 on the left side as an example, the heating plate 400 and the air guide shrouds 300 on both sides together constitute a heating assembly, and the bottom of the air guide shrouds 300 is connected to the base 100. In one embodiment, the width of the heating groove 200 is fixed, and the bottom of the air guide shrouds 300 is fixedly connected to the base 100; in another embodiment, the width of the heating groove 200 is adjustable, and the bottom of the air guide shrouds 300 is slidably connected to the base 100 or detachably connected.

[0020] The air guide shroud 300 is fixedly connected to the heating plate 400. For example... Figure 1 , Figure 2 As shown, the air guide shroud 300 and the heating plate 400 are arranged parallel to each other and are fixedly connected at the edge of the heating plate 400. In one embodiment, the air guide shroud 300 has a side support arm 320, and the side of the heating plate 400 has a side mounting groove that mates with the side support arm 320. The side support arm 320 is inserted into the side mounting groove to mount the heating plate 400. In some embodiments, the air guide shroud 300 also has a bottom support arm 330, and correspondingly, the bottom of the heating plate 400 has a bottom mounting groove that mates with the bottom support arm 330. In other embodiments, the air guide shroud 300 and the heating plate 400 may be connected in other parts or in other ways, which will not be described in detail here.

[0021] The air guide shroud 300 has several air guiding structures. For example... Figure 2 As shown, the air guiding structure includes multiple air guide vanes 310 and air guide holes 315 located on the air guide shroud 300. Hot air is guided by the air guide vanes 310 and flows downward through the air guide holes 315 to reach the interior of the heating tank 200. In one embodiment, the air guide vanes 310 are formed by directly stamping and cutting the metal sheet on which the air guide shroud 300 is located and bending it outward and downward. The air guide holes 315 are the holes formed after the air guide vanes 310 are cut from the metal sheet. One air guide vane 310 corresponds to one air guide hole 315 to form an air guiding structure. Figure 3 In the embodiment shown, the air guiding structure is evenly distributed on the air guiding cover 300, specifically in that it is evenly distributed along the vertical direction of the air guiding cover 300 and / or evenly distributed along the horizontal direction of the air guiding cover 300.

[0022] In one embodiment, the air guide vane 310 includes a fixed section 313, a bent section 312, and an end section 311 connected in sequence, wherein the fixed section 313 may be part of the air guide shroud 300 or fixedly connected to the air guide shroud 300, such as... Figure 2 As shown, the angle between the bent section 312 and the vertical direction is an acute angle α, and the bent section 312 is inclined towards the heating plate 400 with its connection point with the fixed section 313 as a reference, so that the hot air around the heating plate 400 can be introduced through the inclined bent section 312 and pass through the air guide hole 315 located above the reference, as shown. Figure 2 As indicated by the dashed arrow, the bent section 312 uses its upper surface to guide the hot air above it; simultaneously, the bent section 312 also uses its lower surface to block the hot air below it, and continues to introduce the hot air and pass it through another air guide hole 315 located below the reference, thereby achieving an overall air guiding effect for the hot air; the end 311 extends towards the heating plate 400, thereby extending the air guiding distance, and the hot air is divided and enters the air guiding structure earlier. Overall, the two adjacent air guides 310 divide the space between the heating plate 400 and the air guide cover 300 into an inclined air guiding space to a certain extent, so that the hot air generated around the heating plate 400 rises directly as little as possible, but is guided into the heating tank 200 at an inclined downward angle, and gradually rises after contacting the bread slice to be heated, solving the problem that the bottom of the bread slice is difficult to receive hot air, thereby improving heating efficiency and heating effect.

[0023] In one embodiment, the fixed section 313 of the air guide vane 310 is connected to the lower edge of the corresponding air guide hole 315. In another embodiment, the fixed end 313 may also be connected to other parts of the air guide hole 315, or even not connected, as long as it can form an air guide space that slopes towards the bottom of the heating tank 200. The air guide vane 310 can be formed in other ways, such as by installing the air guide vane 310 separately and opening a corresponding air guide hole 315, air guide channel, or air guide gap on the air guide cover 300, as long as it can introduce hot air to the bottom of the heating tank 200. In some embodiments, the air guide vane 310 can be of any shape, for example... Figure 3 The circular air guide 316 shown is not limited to the shape presented in the accompanying drawings of this specification. Figure 4 As shown, multiple horizontally adjacent air guide vanes 310 can also be connected into a single air guide vane assembly, thereby dividing the space with a larger surface area. The hot air above the air guide vane 310 can be guided as much as possible rather than rising directly to dissipate heat before entering the upper air guide hole 315; at the same time, the hot air below the air guide vane 310 can also be effectively blocked and guided as much as possible to the lower air guide hole 315.

[0024] In one embodiment, considering the upward trend of hot air, the number of air guiding structures located on the upper part of the air guide shroud 300' can be appropriately reduced, while the width of the air guiding structures can be increased, such as... Figure 4 As shown, the top row of air guide holes 315' at the top of the air guide shroud 300' consists of two holes, with only one gap between them to allow hot air to escape. From the topmost air guide hole 315' downwards, the number of air guide holes 315' in each row increases sequentially (3, 4, or more). Furthermore, the gaps between any two adjacent air guide holes 315' in each row are blocked from above by the air guide plates 310' in the adjacent upper row. This can be achieved by adjusting the horizontal width of the air guide holes 315'. Figure 4 As shown, the upper part of the air guide shroud 300' has three rows of air guide holes 315'; this can also be achieved by adjusting the position of the air guide holes 315'. Figure 4 The three rows of air guide holes 315' at the lower part of the middle air guide shroud 300' have the same width for each air guide hole 315' and the same spacing between two adjacent air guide holes 315' on the left and right. However, the air guide holes 315' in the upper and lower adjacent rows are staggered in the vertical direction, so that the hot air passing upward through the gap between two adjacent air guide vanes 310' in the lower row is blocked from above by the upper row of air guide vanes 310' and guided by the lower bottom surface of the air guide vane 310' to the air guide hole 315' below it, thereby improving the air guiding efficiency.

[0025] In some embodiments, the width of the air guide plate 310' and the air guide hole 315' is the same, which is regarded as the width of the air guide structure. In one embodiment, all air guide structures have the same width, but the two adjacent rows of air guide structures are staggered in the vertical direction. In another embodiment, some air guide structures have the same width, and the gap between adjacent air guide structures is blocked from above by the air guide structure located above them.

[0026] like Figure 6 As shown, the air guide vane 310' also includes a fixed section 313', a bent section 312', and an end 311' connected in sequence. The fixed section 313' is part of or fixedly connected to the air guide shroud 300'. The angle (bending angle) between the bent section 312' and the vertical direction is an acute angle β. The bent section 312' is inclined towards the heating plate 400 with its connection point with the fixed section 313' as a reference, so that the hot air around the heating plate 400 can be introduced through the inclined bent section 312' and pass through the air guide hole 315' located above the reference. Figure 6 As indicated by the dashed arrow, the bent section 312' uses its upper surface to guide the hot air above it; at the same time, the bent section 312' also uses its lower surface to block the hot air below it, and continues to introduce the hot air and pass it through another air guide hole 315' located below the reference, thereby achieving an overall air guiding effect for the hot air.

[0027] The bending angle β of the bent section 312' varies in different positions within the air guide structure. The bending angle β is larger closer to the lower part of the air guide shroud 300' and smaller closer to the upper part. This is because hot air always tends to rise, and the main challenge in baking bread slices is insufficient bottom heating. Therefore, setting a larger bending angle β near the lower part of the air guide shroud 300' facilitates the entry of hot air into the heating chamber 200. In one embodiment, such as... Figure 5 As shown, the lower bending angle β is 60 degrees, and the upper bending angle β is 45 degrees. In one embodiment, the bending angle is adjustable to accommodate different airflow requirements.
