Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0022] Such as figure 1 As shown, the back-type vortex smoke exhaust system used on air and smoke exhaust products of the present invention includes a volute 01, a centrifugal impeller 02 placed in the volute 01, a motor 03 for driving the centrifugal impeller 02, and the volute The casing 01 has an air inlet 11 in the axial direction (the extension direction of the motor shaft in the figure) and an air outlet 12 in the tangential direction (the tangential direction of the arc part of the volute). The air inlet guide connected to the air inlet 11 is arranged on the volute 01 The channel 04, the port 41 of the air inlet guiding channel is provided with a helical guide blade 42.

[0023] Specifically, in order to be suitable for the downdraft range hood in the integrated stove, the orientation of the port 41 of the air intake guide passage is consiste...

Abstract

The invention discloses a concentric-double-square-shaped vortex fume exhaust system used on an air exhaust and oil fume exhaust product, belongs to oil fume exhaust equipment, and aims at solving the problem that an existing oil fume exhaust system is relatively small in oil fume sucking range. According to the vortex oil fume exhaust system provided by the invention, an air inlet guide passage communicated with an air inlet is arranged on a volute, fixed spiral guide fan blades are arranged in the end hole of the air inlet guide passage; during work, guide air flow spirally enters the end hole of the air inlet guide passage, meanwhile, a vortex is generated at an air inlet in a pressed way, and drives abundant air flow to continuously enter the volute, so that integral sucking force of an oil fume exhauster is powerful, the oil fume sucking range is large, and the effective fume sucking effect is achieved.

Description

technical field [0001] The invention belongs to smoke exhaust equipment, in particular to a return-type vortex smoke exhaust system used in air and smoke exhaust products. Background technique [0002] The range hood is used as a device for exhausting oil fume in the kitchen, and it is used to discharge the oil fume in the kitchen to the outside when cooking. Its structure is different, there are wall-mounted structures, and some are integrated in integrated stoves. However, the smoking range of the existing smoke exhaust system is small, and the smoking effect needs to be further improved. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to overcome the defect that the existing smoke exhaust system has a small range of smoking, and provide a return-type vortex smoke exhaust system used on air and smoke exhaust products. [0004] In order to achieve the above object, the back-type vortex sm...
