Description

Technical Field

[0001] The utility model belongs to the technical field of ultra-thin induction cookers, and in particular relates to a heat dissipation structure of an ultra-thin induction cooker. Background Art

[0002] As one of the commonly used cooking tools in homes and catering places, induction cookers have the characteristics of high efficiency, no open flames, no smoke and dust, safety and hygiene, and can meet people's daily cooking operations. The principle of induction cookers is to use magnetic field induction eddy current heating, that is, to use electric current to pass through the coil to generate a magnetic field. When the magnetic lines of force in the magnetic field pass through the bottom of the iron pot, the magnetic lines of force are cut, thereby generating countless small eddy currents, causing the iron molecules of the iron pot to rotate at high speed, collide and rub to generate heat and heat the food in the pot. When the induction cooker heats the pot, the heat generated during the heating process will be conducted downward into the furnace body, causing the coil disk, control board and other structures located in the furnace body to be affected by the high temperature. Moreover, the control board will also generate a lot of heat when working. In order for the induction cooker to work normally, the heat in the furnace body needs to be discharged in time.

[0003] Ultra-thin induction cookers are popular among people for their small thickness and small space occupation and have broad market value. Conventional ultra-thin induction cookers set a group of heat dissipation fans inside the furnace body to draw air from the external environment into the furnace body and dissipate heat to the coil disk and control board. The problem is that due to the structural limitations of the ultra-thin induction cooker, the space inside the furnace body of the ultra-thin induction cooker is small, and a single group of heat dissipation fans cannot provide sufficient cooling air to meet the heat dissipation needs inside the furnace body of the ultra-thin induction cooker, resulting in poor heat dissipation effect inside the furnace body of the ultra-thin induction cooker. The high temperature environment reduces the life of the coil disk and the control board, resulting in a short service life of the ultra-thin induction cooker, which makes people have a poor experience using the ultra-thin induction cooker.

[0004] Therefore, further improvements are needed. Utility Model Content
