AI Technical Summary

Technical Problem

During the drying stage, the existing dishwasher exhaust pipes have a smaller effective area of ​​the pipe, which affects the drying efficiency. The faster the wind speed will produce a bubble blowing effect on the residual water, making it easy to produce noise.

Method used

An exhaust pipe is designed, and a wind guide tray gradually tilted upward in the direction of the airflow is provided at the first bent structure of the pipe body. The condensed water remains at the first bent structure and is blocked under the wind guide tray. When the wind body passes through the wind guide tray, the wind direction is forced to change to blow upward incline to avoid the problem of blowing the condensate water to produce bubbles.

Benefits of technology

Through this design, the problem of blowing condensate water by wind blowing it into bubbles is avoided, the overall noise is reduced, and the drying efficiency is improved, and the generation of condensate water is reduced.

Abstract

The utility model relates to an exhaust pipe and a cleaning device, the exhaust pipe comprises a pipe body, the pipe body comprises a first pipe section and a second pipe section which are connected with each other, and a first bending structure which extends from the end part of the transverse part of the first pipe section from bottom to top is formed at the lower end of the second pipe section; an air guide table which is arranged close to the first bent structure and gradually inclines upwards in the airflow direction is formed on the inner bottom wall of the end of the transverse part of the first pipe section. Condensate water formed in the pipe body is retained at the first bending structure and blocked below the air guide table, when the air body passes through the air guide table, the air direction is forced to be changed into inclined upward blowing, and the air body cannot pass through the condensate water below the air guide table, so that the problem that bubbles are generated due to the fact that the condensate water is blown by the air is solved, and the overall noise is reduced; the wind speed of the upper side of the bending structure is increased through the closing-in structure at the wind guide table, moisture is exhausted upwards in an accelerated mode when passing through the closing-in structure, the contact time of the moisture and condensate water is shortened, therefore, generation of the condensate water is reduced, and the drying efficiency and effect of the whole machine are improved.
