[0044] Embodiment 1

[0045] like Figures 1 to 5 As shown, this embodiment provides a heat dissipation housing, including a shell 10, the shell 10 has a cavity, the cavity can be used to accommodate electronic components, a heat dissipation hole 101 is set on the first cavity wall of the cavity, the heat dissipation hole 101 penetrates in the thickness direction of the first cavity wall, the cavity is connected to the heat dissipation hole 101, and the heat generated by the electronic components can be timely dissipated to the outside of the shell 10 through the heat dissipation hole 101 to ensure the normal operation of the electronic components in the cavity. Because the heat dissipation hole 101 is connected to the cavity, the situation inside the shell 10 can be intuitively observed from the outside of the shell 10, and the aesthetics are poor. For household appliances, because their usage scenario is a home environment, in addition to foreign objects easily entering the interior of the household appliances through the heat dissipation hole 101, children can also easily put their fingers into the heat dissipation hole 101, and safety is difficult to meet. The heat dissipation housing provided in this embodiment also includes a heat sink, which is arranged at the heat dissipation hole 101. The heat sink includes a first heat sink 1 and a second heat sink 2. The first heat sink 1 and the second heat sink 2 have a gap in the extension direction of the heat dissipation hole 101, so that the cavity can be connected to the external environment of the shell 10 through this gap, ensuring the heat dissipation effect of the electronic components in the cavity. The common projection of the first heat sink 1 and the second heat sink 2 on the first cavity wall fills the heat dissipation hole 101. The projection area of ​​the first heat sink 1 is S1, and the projection area of ​​the overlapping area of ​​the first heat sink 1 and the second heat sink 2 is S11, S11 = a × S1, 0 < a ≤ 50%, thereby preventing foreign matter from entering the cavity through the heat dissipation hole 101 along the extension direction of the heat dissipation hole 101, and the user cannot directly observe the inside of the cavity, which is beautiful and safe.

[0046] Optionally, the heat dissipation hole 101 has a first edge and a second edge, and the first edge and the second edge are connected end to end to form a closed pattern. The first heat sink 1 is connected to the first edge, and the second heat sink 2 is connected to the second edge, that is, each circumferential edge of the heat dissipation hole 101 is provided with a heat sink, which can prevent foreign matter from entering the cavity through the slit between the heat sink and the first cavity wall through the heat dissipation hole 101, and can improve the heat sink's barrier effect on foreign matter.

[0047] Optionally, the first heat sink 1 and the second heat sink 2 are both located on the same side of the first cavity wall. In specific implementation, the first heat sink 1 and the second heat sink 2 can be both arranged on the first side of the first cavity wall, that is, both are located in the cavity, or the first heat sink 1 and the second heat sink 2 can be both arranged on the second side of the first cavity wall, that is, both are located outside the cavity. Because the first heat sink 1 and the second heat sink 2 are located on the same side of the first cavity wall, and there must be a gap between the first heat sink 1 and the second heat sink 2 in the extension direction of the heat dissipation hole 101, the distance between the first heat sink 1 and the second heat sink 2 and the first cavity wall along the extension direction of the heat dissipation hole 101 must be different.

[0048] Preferably, when the first heat sink 1 and the second heat sink 2 are both located outside the cavity, the first heat sink 1 provided at the same heat dissipation hole 101 is located above the second heat sink 2, and in the extension direction of the heat dissipation hole 101, the maximum distance between the first heat sink 1 and the first cavity wall is L1, and the maximum distance between the second heat sink 2 and the first cavity wall is L2, and L1>L2. That is, in the vertical direction, the projection of the first heat sink 1 covers the projection of the second heat sink 2, which can prevent foreign matter from falling between the second heat sink 2 and the outer wall of the housing 10.

[0049] In other embodiments, the first heat sink 1 and the second heat sink 2 are both located in the cavity, and the maximum distance between the first heat sink 1 and the first cavity wall in the extension direction of the heat dissipation hole 101 is L1, and the maximum distance between the second heat sink 2 and the first cavity wall in the extension direction of the heat dissipation hole 101 is L2, and L2≠L1.

[0050] Optionally, the first heat sink 1 and the second heat sink 2 are respectively located on both sides of the first cavity wall. In specific implementation, the first heat sink 1 can be arranged on the first side of the first cavity wall, that is, located in the cavity, and the second heat sink 2 can be arranged on the second side of the first cavity wall, that is, located outside the cavity. The first heat sink 1 can also be arranged on the second side of the first cavity wall, that is, located outside the cavity, and the second heat sink 2 can be arranged on the first side of the first cavity wall, that is, located in the cavity. Since the first heat sink 1 and the second heat sink 2 are respectively arranged on both sides of the first cavity wall, there must be a gap between the first heat sink 1 and the second heat sink 2 in the extension direction of the heat dissipation hole 101.

[0051] like Figure 2 and Figure 3 As shown, in this embodiment, the first heat sink 1 is located outside the cavity, the second heat sink 2 is located inside the cavity, and the first heat sink 1 at the same heat dissipation hole 101 is located on the second heat sink 2. Since the second heat sink 2 is not arranged outside the cavity, foreign matter can be prevented from falling between the second heat sink 2 and the outer wall of the shell 10.

[0052] Optionally, one of the first heat sink 1 and the second heat sink 2 is coplanar with the first cavity wall, and the other of the first heat sink 1 and the second heat sink 2 is located in the cavity. That is, if the first heat sink 1 and the first cavity wall are coplanar, the second heat sink 2 is located in the cavity. In a specific implementation, the first heat sink 1 and the first cavity wall can be an integrally formed structural component. If the second heat sink 2 and the first cavity wall are coplanar, the first heat sink 1 is located in the cavity. In a specific implementation, the second heat sink 2 and the first cavity wall can be an integrally formed structural component.

[0053] Optionally, one of the first heat sink and the second heat sink 2 is coplanar with the first cavity wall, and the other of the first heat sink 1 and the second heat sink 2 is located outside the cavity, that is, if the first heat sink 1 and the first cavity wall are coplanar, the second heat sink 2 is located outside the cavity. In a specific implementation, the first heat sink 1 and the first cavity wall can be an integrally formed structural component. If the second heat sink 2 and the first cavity wall are coplanar, the first heat sink 1 is located outside the cavity. In a specific implementation, the second heat sink 2 and the first cavity wall can be an integrally formed structural component.

[0054] Preferably, the maximum spacing between the first heat sink 1 and the first cavity wall in the extension direction of the heat dissipation hole 101 is L1, and the maximum spacing between the second heat sink 2 and the first cavity wall in the extension direction of the heat dissipation hole 101 is L2, and L2>L1. This can not only satisfy that the first heat sink 1 and the second heat sink 2 have an appropriate spacing in the extension direction of the heat dissipation hole 101 to ensure the heat dissipation effect, but also reduce the degree of protrusion of the first heat sink 1 away from the cavity, thereby improving the aesthetics of the heat dissipation housing.

[0055] Preferably, the spacing between the first heat sink 1 and the second heat sink 2 in the extension direction of the heat dissipation hole 101 is L, L1+L2=L, 0mm<L<20mm. In specific implementation, the spacing between the first heat sink 1 and the second heat sink 2 in the extension direction of the heat dissipation hole 101 can be adjusted according to actual heat dissipation requirements to ensure the flow rate of gas at the heat dissipation hole 101 and ensure the heat dissipation effect.

[0056] Furthermore, the projection of the first side 11 of the first heat sink 1 not connected to the housing 10 on the first cavity wall overlaps with the projection of the second side 21 of the second heat sink 2 not connected to the housing 10 on the first cavity wall, that is, the common projection of the first heat sink 1 and the second heat sink 2 on the first cavity wall just fills up the heat dissipation hole 101, reducing the overlapping area of ​​the first heat sink 1 and the second heat sink 2, so as to meet the heat sink's foreign body blocking effect while reducing the impact on the heat dissipation performance of the heat dissipation hole 101. In this embodiment, the first side 11 and the second side 21 are both straight edges, and the projections of the two straight edges are two overlapping straight lines.

[0057] In this embodiment, the heat dissipation hole 101 is a waist-shaped hole, and the first heat sink 1 includes a first main heat sink and a first side heat sink, the first main heat sink is connected to the straight side of the waist-shaped hole, and the first side heat sink is connected to the arc-shaped side of the waist-shaped hole. The second heat sink 2 includes a second main heat sink and a second side heat sink, the second main heat sink is connected to the straight side of the waist-shaped hole, and the second side heat sink is connected to the arc-shaped side of the waist-shaped hole. In this embodiment, the first heat sink 1 is located above the second heat sink 2, and the first heat sink 1 is connected to the upper half of the waist-shaped hole, and the second heat sink 2 is connected to the lower half of the waist-shaped hole.

[0058] In this embodiment, Figure 6 As shown, the first main heat sink includes a curved area 12 and a flat area 13. The curved area 12 is connected to the shell 10, and the flat area 13 is parallel to the plane where the heat dissipation hole 101 is located, which can further reduce the maximum distance between the first heat sink 1 and the outer wall of the shell 10.

[0059] Optionally, the housing 10 is provided with N heat dissipation holes 101, and the heat dissipation fins are also provided with N heat dissipation fins, and one heat dissipation fin is provided at one heat dissipation hole 101 to improve the heat dissipation efficiency of the heat dissipation housing. Figure 4 As shown, N heat dissipation holes 101 are arranged to form M rows, and the heat dissipation holes 101 in two adjacent rows are staggered to ensure the strength of the housing 10 .

[0060] Embodiment 2

[0061] like Figure 7 As shown, this embodiment provides a cooking device 100, including the above-mentioned heat dissipation housing. The shell 10 of the heat dissipation housing has a cavity, and the cavity can be used to accommodate the electronic components of the cooking device 100. The heat generated by the electronic components can be dissipated from the gap between the first heat sink 1 and the second heat sink 2 to the outside of the cavity, while foreign matter can be blocked outside the cavity by the first heat sink 1 and the second heat sink 2, and the user cannot directly observe the situation in the cavity, that is, while meeting the heat dissipation requirements of the cooking device 100, the safety and aesthetics of the cooking device 100 can be improved.
