Problems solved by technology

However, the wind blown by the above-mentioned installed axial flow fan will blow to the heating elements in the heat dissipation area scatteredly through the heat dissipation channel formed between the fan and the upper cover assembly and / or the base, so that the air is not concentrated and cannot be fully efficient. At the same time, the wind blown by the axial flow fan will be refracted back due to the cover of the upper cover assembly and / or the base, reducing the part of the air volume dispersed to the heat dissipation area, and further causing the heat dissipation effect of the heating element to be poor. Long-term use will easily cause damage to the heating element, which greatly affects the service life of the desktop furnace

Embodiment 1

[0030] Taking the induction cooker as an example, the induction cooker of Embodiment 1 includes a top cover assembly and a horizontal base 1, the top cover assembly includes a top cover and a microcrystalline plate, the microcrystalline plate is installed on the top cover, and the base 1 and the top cover assembly form a furnace chamber. The furnace cavity is provided with heating elements such as a coil disk 2 , a circuit board 3 , capacitors, inductors, transformers and switch chips, and a heat dissipation structure including an axial flow fan 4 and a fan cover 5 . The heat dissipation structure is used to export the heat generated by the heating element out of the furnace cavity, so as to avoid damage or danger to the induction cooker caused by excessive heat generation.

[0031] In Example 1, such as figure 1 As shown, the axial flow fan 4 of the heat dissipation mechanism is obliquely installed on the base 1 through the support 6, and an included angle of 35°-60° is forme...

Embodiment 2

[0039] The structure of the induction cooker disclosed in Embodiment 2 is basically the same as the structure of the induction cooker described in Embodiment 1. That is, the induction cooker includes an upper cover assembly and a base 1, the upper cover assembly includes an upper cover and a microcrystalline plate, the microcrystalline plate is installed on the upper cover, the base 1 and the upper cover assembly form a furnace cavity, and a coil disk 2, Circuit board 3 , heating elements such as capacitors, inductors, transformers and switch chips, and a heat dissipation structure including axial flow fan 4 and fan cover 5 . The structure of the axial flow fan 4 is the same as that of the axial flow fan described in Embodiment 1, and will not be repeated here. The axial flow fan 4 is obliquely installed on the base 1 through the support 6, and the air outlet of the axial flow fan 4 is close to and facing the above-mentioned heating element of the desktop furnace. Wherein, th...

Embodiment 3

[0043] In order to further improve the heat dissipation effect of the heating element, Embodiment 3 is further improved on the basis of the heat dissipation structure of the induction cooker described in Embodiment 1 or Embodiment 2.

[0044] The improvement is that: an air guide part is arranged on the upper surface of the cover body of the fan cover 5, and the air guide part is arranged on the periphery of the circular opening in the center of the fan cover 5, and extends toward one side of the heating element, which can control the axial flow. The wind blown out by type fan 4 plays the role of guiding and concentrating, so that more air can be concentrated and efficiently blown to the heating element, and the heat generated by the heating element is taken away from the furnace chamber. The air guide part can be fixedly connected with the fan cover 5 through fasteners (such as screws, bolts), can be clamped with the fan cover 5 through a buckle structure, and can also form an...

Abstract

The invention discloses a table furnace heat dissipation structure and relates to the field of household appliances. The heat dissipating structure comprises an axial flow fan installed between an upper cover assembly and a base of a table furnace. The axial flow fan is inclinedly installed on the base. An air outlet of the axial flow fan is close to and faces to a heating element of the table furnace. The invention also discloses a table furnace with the table furnace heat dissipation structure, the axial flow fan in the table furnace is installed obliquely to the base and the air outlet of the axial flow fan is close to and faces to the heating element of the table furnace so that air blown by the axial flow fan can be intensively blown to the heating element and heat of the heating element can be fully and efficiently dissipated. The table furnace heat dissipation structure has good heat dissipation effects, prevents refraction of air blown by the axial flow fan caused by upper cover assembly and / or base blocking, improves the air amount of the heating element, improves the heat dissipation effects of the heating element and prolongs the service life of the table furnace.

Description

technical field [0001] The invention discloses a table top furnace heat dissipation structure and a table top furnace with the table top furnace heat dissipation structure, relating to the field of household appliances. Background technique [0002] In the existing desktop furnace (such as induction cooker) heat dissipation device, a single fan or double fans are used to dissipate heat by blowing air to the heating elements (such as radiators, circuit boards and coil coils) in the furnace cavity of the desktop furnace. In desktop furnaces, axial flow fans are generally used to dissipate heat from the above-mentioned heating elements, which is not only efficient, safe, and energy-saving, but also easy to disassemble and assemble, saving installation space and reducing installation costs. [0003] In order to dissipate the heat generated by the heating element in a timely manner and meet the ultra-thin design requirements of the desktop furnace, the axial flow fans of most des...
