Problems solved by technology
However, when the temperature rise of the motor samples sent by the motor factory does not meet the standard, in general, it is necessary to communicate with the motor factory many times and improve the motor factory many times before it is possible to obtain a motor that meets the performance requirements, which is very costly in manpower, material and financial resources; even The temperature rise of the motor samples sent by the motor factory meets the standard, but the mass-produced motors may still have more temperature rises that do not meet the standard

Embodiment Construction
[0028] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.
[0029] See Figure 1 ~ Figure 3 , A side suction range hood, comprising a housing 1, a panel 2 arranged obliquely on the front side of the housing 1. The panel 2 is provided with an air inlet 21, and a smoke shield 3 adapted to the size of the air inlet 21 is rotatably arranged on the panel 2, and can be rotated relative to the panel 2 to open or close the air inlet 21.
[0030] A fan 4 is arranged in the housing 1, and the fan 4 includes a volute 41, an impeller 42 arranged in the volute 41, and a motor 43 for driving the impeller 42 to rotate. An oil guide plate (not shown) may be arranged between the volute 41 and the panel 2, and the air inlet formed on the volute 41 and the oil guide plate corresponds to the air inlet 21 on the panel 2.
[0031] The housing 1 includes a back plate 11 on the rear side and a top plate 12 on the top. In this embodiment, the...

The invention discloses a side suction type range hood. The side suction type range hood comprises a shell and a fan arranged in the shell, wherein the shell comprises a back plate arranged at the rear side; the fan comprises a volute, an impeller arranged in the volute, and a motor used for driving the impeller to rotate. The side suction type range hood is characterized in that the back plate isprovided with an air vent for allowing the air flow outside the range hood to enter the shell, and the fan is provided with an air flow passage for allowing the air flow to enter the fan via the space between the back side of the volute and the back plate so as to accelerate the flow of the air around the motor. Compared with the prior art, the side suction type range hood has the advantages thatby arranging the air flow passage between the inside and the outside of the range hood and the air flow passage between the outside of the volute and the inside of the impeller, the outside air can accelerate the flow of the air around the motor, so that the heat dissipation performance of the motor is enhanced, and the temperature rise of the motor is reduced.
Description
Technical field [0001] The invention relates to oil fume purification equipment, in particular to a side suction type range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern households. Generally, range hoods include top-suction type and side-suction type. The top-suction type range hood uses the principle of rising heat to absorb and discharge the natural rising oil fume generated during cooking. In addition, it is also clean and light, and takes up less space. Has more and more widespread applications. The side-suction range hood uses the principle of vortex air pressure to absorb most of the cooking fume that is close to the stove in an arc form, which can reduce the adverse effects on human health, and the power source is closer to the stove, basically Will not reduce the suction effect of the power source. [0003] A top-suction range hood, such as a range hood disclosed in the Chinese Patent Application No. 20...
