Description

Technical Field

[0001] This utility model relates to the field of induction cooker technology, and in particular to a heat dissipation structure for an induction cooker. Background Technology

[0002] Induction cookers have advantages such as rapid heating, no open flame, no smoke, safety and convenience, and are increasingly favored and recognized by consumers.

[0003] An induction cooker mainly consists of: a bottom shell, a panel on the bottom shell, a coil inside the bottom shell, a circuit board assembly, and a cooling fan. The cooling fan is used to dissipate heat from the heating elements such as the coil and circuit board assembly. Air inlets are located on the sides of the bottom shell, and air outlets are located on the bottom surface. The cooling fan blows air from inside the induction cooker out through the air outlets while simultaneously drawing in outside air through the air inlets, thus achieving heat dissipation.

[0004] However, this type of induction cooker also has the following problems. Due to the size limitation of the induction cooker itself, the distance between the air inlet and the air outlet is only a few centimeters or twenty centimeters, which easily leads to cross-flow of air. The hot air coming out of the air outlet has not been completely cooled before it is drawn back into the induction cooker through the air inlet, resulting in unsatisfactory heat dissipation. Especially in the hot summer, this heat dissipation efficiency is difficult to meet the requirements. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a heat dissipation structure for an induction cooker that can reduce air leakage.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] A heat dissipation structure for an induction cooker includes a bottom shell with supporting legs, a heat dissipation fan, and a panel covering the bottom shell; the heat dissipation fan is located in the inner cavity formed by the bottom shell and the panel; a first air inlet is provided on the rear side wall of the bottom shell, communicating with the inner cavity; a wind baffle structure is provided on the outer bottom surface of the bottom shell, the wind baffle structure forming an air outlet cavity with the opening facing forward; and an air outlet hole is provided on the bottom wall of the bottom shell, connecting the inner cavity and the air outlet cavity.

[0008] As a further optimization of the above technical solution, the windbreak structure is U-shaped or C-shaped, and the air outlet is located inside the air outlet cavity or at the opening of the air outlet cavity.

[0009] As a further optimization of the above technical solution, a second air inlet is provided at the rear of the left side wall of the bottom shell, and a third air inlet is provided at the rear of the right side wall of the bottom shell.

[0010] As a further optimization of the above technical solution, a transition inclined plate is provided between the bottom wall and the front side wall of the bottom shell, the angle B between the transition inclined plate and the panel is 25 to 60 degrees, and the opening of the air outlet cavity faces the transition inclined plate.

[0011] As a further optimization of the above technical solution, the windbreak structure is a rib fixed on the bottom wall of the bottom shell, and the lower edge of the rib is not lower than the lowest point of the support foot.

[0012] As a further optimization of the above technical solution, the windbreak structure is an elastic rubber strip set on the bottom wall of the bottom shell, and the lower edge of the elastic rubber strip is flush with the lowest point of the support foot.

[0013] As a further optimization of the above technical solution, two clamping plates are provided on the bottom shell, and the upper part of the elastic rubber strip is clamped between the two clamping plates.

[0014] The beneficial effects of this invention are: after the hot air inside the induction cooker is blown out from the air outlet, under the restriction of the baffle structure, this hot air will basically flow forward from the opening of the air outlet cavity formed by the baffle structure, which can effectively prevent this hot air from being directly drawn into the induction cooker from the first air inlet before it has cooled down. The anti-wind-crossing effect is excellent. Attached Figure Description

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicator will also change accordingly. Furthermore, descriptions involving "preferred," "second-preferred," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "preferred" or "second-preferred" may explicitly or implicitly include at least one of those features.

[0021] Reference Figures 1 to 4 An induction cooker includes a bottom shell 1 with supporting feet 11, a coil 2, a circuit board assembly 3, a cooling fan 4, and a panel 5 covering the bottom shell 1. The coil 2, circuit board assembly 3, and cooling fan 4 are located in the inner cavity formed by the bottom shell 1 and the panel 5. A first air inlet 101 communicating with the inner cavity is provided on the rear side wall of the bottom shell 1. A wind baffle structure is provided on the outer bottom surface of the bottom shell 1, forming an air outlet cavity 200 with the opening facing forward. An air outlet 105 communicating with the inner cavity and the air outlet cavity 200 is provided on the bottom wall of the bottom shell 1. The wind baffle structure is U-shaped or C-shaped, and the air outlet 105 is located inside the air outlet cavity 200 or at the opening of the air outlet cavity 200.

[0022] Reference Figure 1 The cooling fan 4 is located directly above the air outlet 105 and is fixed with screws. When the induction cooker is working, the cooling fan 4 blows air from inside the induction cooker out through the air outlet 105, while simultaneously drawing in external air through the air inlet, thus achieving heat dissipation. After the hot air inside the induction cooker is blown out of the air outlet, it is largely contained by the baffle structure and flows forward through the opening of the air outlet cavity 200 formed by the baffle structure. This effectively prevents the hot air from being directly drawn into the induction cooker through the first air inlet 101 before it has cooled down. The anti-crossflow effect is excellent.

[0023] Furthermore, a second air inlet 102 is provided on the rear part of the left side wall of the bottom shell 1, and a third air inlet 103 is provided on the rear part of the right side wall of the bottom shell 1.

[0024] Furthermore, a transition ramp 104 is provided between the bottom wall and the front side wall of the bottom shell 1. The angle B between the transition ramp 104 and the panel 5 is 25 to 60 degrees, such as 30 degrees or 40 degrees. The opening of the air outlet 200 faces the transition ramp 104. With this design, while ensuring that the area of ​​the panel 5 remains unchanged, hot air from the induction cooker can be quickly discharged from the space under the transition ramp 104, cooled down quickly, and further improved heat dissipation efficiency.

[0025] Reference Figure 2 In a preferred embodiment of this utility model, the windbreak structure is a rib 21 fixed to the bottom wall of the bottom shell 1, and the rib 21 and the bottom shell 1 are integrally formed. The lower edge of the rib 21 is not lower than the lowest point of the support foot 11. Since the rib 21 may deform during the forming process, the lower edge of the rib 21 is generally designed to be slightly higher than the lowest point of the support foot 11.

[0026] Reference Figure 4In another preferred embodiment of this utility model, the windproof structure is an elastic rubber strip 22 disposed on the bottom wall of the bottom shell 1, the lower edge of the elastic rubber strip 22 being flush with the lowest point of the support foot 11. Specifically, two clamping plates 15 are disposed on the bottom shell 1, and the upper part of the elastic rubber strip 22 is clamped between the two clamping plates 15. The elastic rubber strip 22 can be fixed by interference fit or by fasteners such as screws and rivets.

[0027] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
