Washing and drying integrated machine and method for automatically cleaning thread scraps

Abstract

The invention discloses a washing and drying integrated machine and a method for automatically cleaning thread scraps. The washing and drying integrated machine comprises an outer cylinder and a drying assembly, wherein an air outlet communicated with a drying air duct is formed in the outer cylinder, and a filter screen for filtering air flowing through the air outlet is arranged at the air outlet; the distance between the lowest position of the air outlet and the lowest position of the inner wall of the outer cylinder in the vertical direction is L, the diameter of the outer cylinder is D, and L: D is 0-0.15. The position of the air outlet is lower, the filter screen is arranged at the air outlet and soaked in washing water in a clothes washing state, or the liquid level of the washing water is close to the filter screen, so that water flow can reach the filter screen in the washing process to flush the thread scraps on the filter screen, long-time soaking or water flow impact of thefilter screen is realized in the washing process, automatic cleaning is realized, the workload of a user is reduced, and the thread scraps on the filter screen are cleaned up.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and specifically provides an integrated washing and drying machine and a method for automatically cleaning lint. Background technique [0002] With the development of science and technology and the improvement of economic level, more and more users have begun to pay attention to and choose the integrated drum washer and dryer. During the drying process, the lint of the clothes in the inner cylinder will be brought to the drying air duct and heat exchanger by the wind generated by the drying fan. The accumulation of lint will reduce the air volume of the drying air duct and improve the exchange efficiency of the heat exchanger. It is also reduced, thereby reducing the drying efficiency, and it is necessary to prolong the drying time and increase the drying energy consumption. [0003] At present, the washing and drying integrated machine on the market mainly uses a filter screen in the d...

AI Technical Summary

Problems solved by technology

[0003] At present, the washing and drying integrated machine on the market mainly uses a filter screen in the drying air duct to deal with lint in the drying system, and the user regularly cleans it; the disadvantage of this method is that it increases the workload of the user, and second, if the user Without the habit of cleaning the filter screen regularly, it will still cause unsatisfactory drying effect and affect the service life of the product

Therefore, a technology that can automatically clean up the lint has appeared, and the spray structure for spraying the filter screen has been set, and the filter screen is automatically flushed for a period of time before the end of the drying process, which plays the role of automatically cleaning the lint on the filter screen; The lint is very easy to adhere to the surface of the object and the adhesion is relatively strong. Only relying on the water flow through the solenoid valve can not get a good flushing effect, and the actual lint cleaning effect is not ideal.
