Problems solved by technology

[0003] At present, the air duct systems of integrated stoves and range hoods on the market are all fixed to the volute by the motor, which causes the volute to bear a large structural force and limits the direction of exhaust air.
In order to realize exhaust at different positions, a conversion device is designed at the exhaust outlet of the volute, which affects the exhaust performance. The existing volute exhaust usually installs a turning plate in the flue, which makes the volute exhaust There is a certain wind resistance

Embodiment

[0034] Embodiment: a kind of air duct system reversing device, such as Figure 1-Figure 12 As shown, it includes a negative pressure box and a fan system. The negative pressure box includes a bottom plate 1, a surrounding plate 2 arranged around the upper surface of the bottom plate 1 and a cover plate 3 installed on the upper side of the surrounding plate 2. Said coaming plate 2 is provided with coaming plate holes 201 on the left and right sides of the rear portion, and one of the coaming plate holes 201 can be used quickly when needed. The fan system is arranged on the inner side of the negative pressure box. It includes a volute 4, a motor 5, an impeller 6, a hand nut 7, an air guiding ring 8, an adapter sleeve 9 and an air outlet pipe 10. The raised part 203, the motor 5 is installed on the upper surface of the base plate 1 and on the inside of the raised part 203. After the fan system is installed on the inside of the raised part 203, the rear side of the enclosure 2 has...

Abstract

The invention discloses an air duct system reversing device, and belongs to the technical field of kitchen smoke exhaust equipment. Installation of a fan system is comprehensively optimized, the structure is improved, and the problems that a volute needs to bear structural force and an electric appliance provided with a volute wind power system needs a rotating device to exhaust air at different positions are solved. Not only is the cost saved, but also the suction and discharge capacity of the fan system can be improved, and the purposes of energy conservation and consumption reduction are achieved. The direct exhaust technology between the volute and an air outlet pipe structure is adopted, the air outlet resistance is effectively reduced, so that the purposes of saving energy, reducing consumption, improving performance and reducing noise are achieved, and meanwhile, the cost is reduced due to the fact that parts used for converting the air outlet direction are reduced.

Description

technical field [0001] The invention belongs to the technical field of kitchen smoke exhaust equipment, and in particular relates to a reversing device for an air duct system. Background technique [0002] Integrated stove, also known as environmental protection stove or integrated environmental protection stove in the industry, integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It has the effect of saving space and extracting oil fume Good, energy saving, low consumption and environmental protection. [0003] At present, the air duct systems of integrated stoves and range hoods on the market are all fixed to the volute by the motor, which causes the volute to bear a large structural force and limits the direction of exhaust air. In order to realize exhaust at different positions, a conversion device is designed at the exhaust outlet of the volute, which affects the exhaust pe...
