Problems solved by technology
The heat dissipation fan in this patent is a cross-flow fan, and the heat dissipation box constitutes the only heat dissipation channel. This heat dissipation structure requires a large amount of air, which makes the noise generated by the cross-flow fan also relatively large. In addition, this heat dissipation structure can make the oven The heat generated during the working process is taken away, and the heat generated by the upper control circuit board can also be reduced
However, the door body of the oven has a problem of high temperature during operation, and the heat dissipation structure of the existing oven cannot effectively dissipate heat from the door body of the oven.

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] Such as Figure 1-10 As shown, an oven includes a box body 1 , an inner container 100 is arranged inside the box body 1 , a door body 2 is arranged on the front of the box body 1 , and a heat dissipation structure is arranged on the top of the inner container 100 .
[0028] The above-mentioned door body 2 includes an outer glass 21 and a middle glass 22 arranged in parallel front and back, and a heat dissipation gap 23 is formed between the outer glass 21 and the middle glass 22, and the heat dissipation gap 23 opens up and down, and is respectively a top inlet 231 and a bottom outlet 232. The top of the liner 100 has a top plate 11 , and the top plate 11 is covered with an air deflector 3 , and the air deflector 3 and the top plate 11 enclose a heat dissipation channel 30 . One end of the heat dissipation passage 30 is an air inlet po...

The invention relates to an oven heat dissipation structure which comprises a heat dissipation channel; one end of the heat dissipation channel is an air inlet port, and the other end of the heat dissipation channel is an air outlet port; a centrifugal fan assembly is arranged on the air inlet port; the centrifugal fan assembly comprises an air guide channel and a centrifugal fan; the air guide channel comprises a volute-shaped air guide cavity and an air inlet cavity; an impeller of the centrifugal fan is arranged in the air guide cavity; the air guide cavity is provided with an air inlet andan air outlet; the air outlet is in fluid communication with the air inlet port; the air inlet cavity communicates with the air guide cavity through the air inlet; and the air inlet cavity communicates with at least one air inlet channel. The oven heat dissipation structure has the characteristics of large air volume and low noise; and in addition, the air inlet amount of the air guide channel isincreased through the air inlet cavity, and cold air entering the air inlet cavity can be mixed in the air inlet cavity, so that interference of external airflow vortex on operation of the impeller can be reduced, operation noise of the impeller is reduced, and airflow can smoothly enter the air guide cavity and is guided into the heat dissipation channel under the action of centrifugal force ofthe impeller.
Description
technical field [0001] The invention relates to the field of ovens, in particular to an oven heat dissipation structure. Background technique [0002] Traditional ovens generally adopt a cross-flow fan and a single heat dissipation channel to dissipate heat from the oven. For example, the Chinese Utility Model Patent No. ZL201120306724.0 (CN202173286U) discloses an electric oven, which has a cabinet with a door, and the cabinet The top of the cooling box is provided with a cooling box, and the cooling box has an air outlet that exposes the front face of the box body. The side wall of the cooling box also has an air inlet for the external hot air to enter the cooling box. The air guide port of the box body and the heat dissipation box, and a heat dissipation fan that discharges the hot air entering the heat dissipation box to the air outlet is also installed in the heat dissipation box. The heat dissipation fan in this patent is a cross-flow fan, and the heat dissipation box...
