Description

Technical Field

[0001] The utility model relates to the field of kitchen and bathroom appliances, in particular to an induction cooker with a novel heat dissipation air duct. Background Art

[0002] Most multi - head induction cookers are installed in embedded cabinets, and there are usually other electrical appliances such as ovens and disinfection cabinets under the induction cooker, which results in a smaller space, poor heat dissipation air intake and exhaust effects of the induction cooker. When heating simultaneously, there is a hidden danger that the temperature of electrical components of the induction cooker rises too high or exceeds the standard. Especially, the electronic control board itself also generates heat. At this time, due to insufficient heat dissipation efficiency, when the temperature rise exceeds the standard, the whole machine electronic control will protect and shut down in advance, and in severe cases, it will cause problems such as circuit board damage, seriously affecting the service life of the electrical appliance and the consumer experience.

[0003] According to the above, the heat dissipation air duct structure of the existing induction cooker needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency of poor heat dissipation effect of the existing induction cooker, and provide an induction cooker with a novel heat dissipation air duct. By setting a heat dissipation air duct with reverse air suction, the air flow blows from top to bottom and then diffuses around, with a wider heat dissipation area and better heat dissipation effect, which can effectively prevent the temperature of electrical components from rising too high due to insufficient heat dissipation, thus damaging the circuit board.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an induction cooker with a novel heat dissipation air duct, including a panel and a body. The panel is arranged on the upper side of the body. The body includes a first accommodating cavity for installing a coil disc and a second accommodating cavity for installing electrical components. The first accommodating cavity and the second accommodating cavity are separated by a partition. The first accommodating cavity is arranged on the upper side of the second accommodating cavity. A heat dissipation air duct is arranged in the first accommodating cavity. The heat dissipation air duct includes an air inlet and a through hole arranged on the partition. The air flow enters the heat dissipation air duct from the air inlet and then enters the second accommodating cavity through the through hole.

[0006] The utility model sets the air inlet on the upper side, guides the air flow to flow from top to bottom through the through hole, and then diffuses around in the second accommodating cavity. Compared with the prior art, the induction cooker with a novel heat dissipation air duct of the utility model reserves the space of the second accommodating cavity for heat dissipation, with a wider heat dissipation area and better heat dissipation effect.

[0007] Preferably, the first accommodating cavity further includes an extension portion. The extension portion and the outer wall of the second accommodating cavity form a stepped structure, and the air inlet is provided on the extension portion. The stepped structure provides a larger air inlet surface and reserves sufficient space for air intake. A first flow guiding wall is provided on the partition board. The first flow guiding wall encloses the air inlet and the through hole to form the heat dissipation air duct. The first flow guiding wall guides the air flow from the air inlet to the through hole, so that the air flow enters the second accommodating cavity for heat dissipation.

[0008] Preferably, a heat dissipation device is further included. The heat dissipation device is arranged in the middle of the second accommodating cavity and corresponds to the through hole. The electrical components are distributed around the heat dissipation device. An air outlet is provided on the peripheral wall of the second accommodating cavity. After the air flow enters the second accommodating cavity, it diffuses around and is discharged from the air outlet. When the air flow enters the second accommodating cavity through the through hole, the heat dissipation device diffuses the air flow around, and air outlets are arranged on the peripheral wall to maximize the diffusion range of the air flow, thereby improving the heat dissipation effect.

[0009] Preferably, second flow guiding walls are provided on both sides of the heat dissipation device to form a second heat dissipation air duct with openings on the left and right sides. The electrical components are arranged at the openings of the second heat dissipation air duct. The second flow guiding walls can guide the air flow to the electrical components and enhance the heat dissipation of the electrical components.

[0010] Preferably, the first accommodating cavity further includes a heating cavity. The heat dissipation air duct and the heating cavity are separated by the first flow guiding wall. By blocking the heating cavity and the heat dissipation air duct with the first flow guiding wall, they do not affect each other, preventing the hot air flow in the heating cavity from entering the heat dissipation air duct or the cold air flow in the heat dissipation air duct from entering the heating cavity, thereby improving the heating efficiency and heat dissipation effect.

[0011] Preferably, a touch control circuit board is further included. The touch control circuit board is arranged on the extension portion and above the air inlet.

[0012] Preferably, strip-shaped protrusions are evenly distributed on the peripheral wall of the second accommodating cavity. The air outlet is arranged at the connection between the protrusion and the second accommodating cavity. On the one hand, arranging protrusions on the peripheral wall of the second accommodating cavity can increase the area of the peripheral wall of the second accommodating cavity. The air outlet is arranged on the protrusion, which can increase the number and area of the air outlets and enlarge the air outlet area. On the other hand, the air outlet is arranged at the right-angle connection between the protrusion and the second accommodating cavity, and the air outlet is in an "┐" shape, which is convenient for the air flow to be discharged from different directions and improves the heat dissipation effect.

[0013] Preferably, the air inlet is set in a fish scale shape, and the air outlet is set in a strip shape. Preferably, the fish scale-shaped protrusions of the air inlet are arranged in the heat dissipation air duct. The fish scale-shaped air inlet has a guiding effect on the air flow, which can guide the air flow from the side without protrusions to the side with fish scale-shaped protrusions, that is, guide the air into the heat dissipation air duct.

[0014] Preferably, the coil disk is installed in the heating cavity, a magnet block is arranged under the coil disk, the coil disk adopts a single-strand flat aluminum wire coil disk, and the magnet block adopts a whole-piece super high-permeability magnet; the single-strand flat aluminum wire coil disk can reduce the wire resistance value and the possibility of burning the disk caused by wire breakage, and the whole-piece magnet form of the super high-permeability magnetic material can improve the energy efficiency and increase the shielding of the electromagnetic field.

[0015] Preferably, the panel adopts glass-ceramics. Description of the Drawings
