Bidirectional air discharge type air exhaust pipe for integrated cooker

Abstract

The invention discloses a bidirectional air exhaust type air exhaust pipe for an integrated cooker. The air exhaust pipe is in a bidirectional symmetrical structure form; an air exhaust pipe main bodystructure is composed of a forward air exhaust bent pipe, a transition section, a reverse air exhaust bent pipe, a conical valve slice and a connection ring; the conical valve slice is in the shape suitable for covering inlets of the forward air exhaust bent pipe and the reverse air exhaust bent pipe, the conical valve slice is slidably installed on a slideway on the inner wall of the connectionring through a slide sheet at the semicircular end of the conical valve slice, and a valve slice rotation handle is fixed to the slide sheet; the transition section and a tee-joint variable cross-section adapter are connected through the connection ring; the connection ring is provided with the slideway, and a stop column is fixed to the slideway; the transition section is a variable diameter connection pipe, an inlet of the connection pipe is rectangular, and an outlet of the connection pipe is circular; and the connection ring, the forward air exhaust bent pipe and the reverse air exhaust bent pipe are connected through the tee-joint variable cross-section adapter. Compared with a traditional air exhaust pipe for an integrated cooker, through the bidirectional air exhaust type air exhaust pipe for the integrated cooker, the problems that the air exhaust quantity of the integrated cooker in the air exhaust process is not enough, the air pipe pressure loss is large can be solved, through the novel conical valve slice, air exhaust pipe direction selection is controlled, and the difficulty during air exhaust pipe direction changing is reduced.

Description

technical field [0001] The invention relates to an air outlet pipe for a household integrated cooker, in particular to a two-way exhaust type air outlet pipe for an integrated cooker. Background technique [0002] Household integrated stoves need to consider the left and right air outlets, so it is necessary to install a three-way air outlet pipe at the air outlet. At present, the air outlet pipes for integrated stoves on the market are usually standard three-way pieces, such as Figure 7 As shown, when the standard 90° tee pipe is used as an elbow, the local resistance coefficient ζ at the elbow is often greater than 1.3. The inlet section of this type of tee pipe has a 90° strong bend with respect to the outlet section, and the large curvature deflection angle leads to insufficient air volume, large flow loss, and low effective smoke exhaust volume, which is not conducive to the exhaust of oil fume. At the same time, a large amount of oil accumulates at the 90° transition...

AI Technical Summary

Problems solved by technology

[0003] The air outlet pipe of the traditional range hood relies on the valve plate to change the direction, and the structure does not change after the direction change, which is not conducive to exhaust; in order to overcome the large pressure loss of the air outlet pipe used in the traditional integrated stove, the decrease of the air volume, and the complicated reversing operation, etc. Disadvantages, the present invention provides a two-way exhaust type air outlet pipe for integrated stoves
