Embodiment Construction

[0012] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0013] As shown in the figure: an inlet pipe 2 and an outlet pipe 3 are arranged on the tubular housing 1, and an oil droplet collecting device 4 connected to the inner wall surface is arranged on the housing 1 above the inlet pipe 2, and the inlet pipe 2 and the shell The body 1 is eccentrically arranged, and the casing 1 is provided with a guide tube 5 coaxial with the outlet pipe 2 and extending into the inner cavity of the casing 1. The end surface of the guiding tube 5 extending into the casing 1 is a curved surface. The side of the curved surface close to the inlet pipe 2 is higher than the side away from the inlet pipe 2 .

[0014] The diameter of the outlet pipe 3 is greater than the diameter of the housing 1, so that the outer wall of the housing 1 and the inner wall of the outlet pipe 2 form a gap, and the oil drop collection device 4 is arranged belo...

Abstract

The invention relates to a vortex type of a negative pressure generator used in the kitchen. According to the technical scheme provided by the invention, an inlet pipe and an outlet pipe are mounted on a tubular shell body; an oil drip collection device which is connected with the inner wall of the shell body is mounted on the shell body on top of the inlet pipe; the inlet pipe in the eccentric arrangement with the shell body; a scroll guiding pipe in the same axis with the outlet pipe is mounted on the shell body and extends into the inner cavity of the shell body; the end surface of the scroll guiding pipe which extends into the shell body is a curve surface; the end surface close to the inlet pipe inclines downwards to the end surface apart from the inlet pipe, which constitutes the curve surface. The invention has the good smoke and gas suction capability, less noise during working and low production cost and application cost; most tiny oil drips are absorbed and collected in the inner wall of the shell body during the suction of oil and smoke, which decreases the environmental pollution of the discharge oil and smoke.

Description

technical field [0001] The invention relates to a cooker fume extraction device for kitchen, in particular to a vortex negative pressure generator for kitchen. Background technique [0002] At present, the structure of the range hood used in general households mainly includes a casing, an inner casing, a motor, a fan, a key switch, a lighting lamp, a light shield, an oil collection cover, an oil collection box, and a power cord. Chassis: including side panels, top panels and masks, made of cold-rolled steel plates (some are stainless steel plates) stamped and welded. scrub. Inner shell: The inner shell is generally made of ABS plastic injection molding, with arc-shaped partitions inside, forming a left-right symmetrical spiral inner chamber, and its inner diameter just keeps a certain gap with the fan. When the fan rotates at high speed, due to the centrifugal force, the smoke oil is sucked away, and the dirty oil is thrown to the lowest point of the helix, and enters and ...
