Clothes drying machine and working method thereof

Abstract

The invention discloses a working method of a clothes drying machine.The clothes drying machine comprises a control device, a containing chamber containing dried clothes, an air circulating channel communicated with the containing chamber, and a condensing device supplying water into the air circulating channel to condense dry air from the containing chamber.An air blowing device is arranged in the air circulating channel so as to make dry air circularly flow in the clothes containing chamber and the air circulating channel.The working method is characterized by including the step of checking condensate water through the control device; in the step, the control device starts the condensing device, and whether the condensing device provides water or not is judged according to the change of the rotating speed or working current of the air blowing device before and after the condensing device is started or a certain period of time after the condensing device is started.In addition, the invention further provides the clothes drying machine for implementing the working method.

Description

【Technical field】 [0001] The invention relates to a working method of a clothes dryer, and to a clothes dryer capable of realizing the working method. 【Background technique】 [0002] Existing clothes dryers and clothes dryers that integrate washing and drying functions usually have the following drying process: under the action of the heating device, the dry air is heated in the heating pipe to become dry. Then enter the clothes holding room to exchange heat with the wet clothes, take away the moisture in the clothes to form relatively humid hot air, then enter the condensing device through the outlet set on the holding room, and pass through the condensation of the condensing device function, the moisture in the relatively humid hot air is condensed into water, and then discharged through the drain pipe, and the condensed air becomes relatively dry cold air, which is reintroduced into the heating tube under the action of the fan, and is heated to form dry air. The hot air ...

AI Technical Summary

Problems solved by technology

However, since the flow rate of condensed water is generally very small, ranging from about 0.25 liters / minute to 1 liter / minute, flow sensors for small flows currently on the market often have low detection accuracy and are expensive

The disadvantage of judging whether the condensation valve supplies water or the size of the water supply by detecting the water pressure in the clothing storage room after the condensation valve is opened for a period of time is that the water intake time and pressure increase due to the influence of factors such as the accuracy of the mechanical system and the user's water pressure. If the water inlet time is set too long, cooling water may enter the inner bucket and soak the clothes. If the water inlet time is set too short and the pressure parameter is set too low, the detection accuracy will not be high and errors will easily occur. In addition, before the start of drying, the water supply is detected through additional water intake. At this time, the machine is in the cold waiting stage, which wastes the cooling water supplied by this part, and also wastes the running time of the drying program.
