Control method of clothes dryer

Abstract

The invention discloses a control method of a clothes dryer. The clothes dryer comprises a roller and an electromagnetic heating module arranged outside the roller; when a drying program is entered, the electromagnetic heating module is started, and the roller is controlled to rotate at different rotating speeds along with the proceeding of the drying program. And while the electromagnetic heatingmodule is started, the roller is controlled to rotate at a first rotating speed V1, and after rotating for a certain time, the roller is decelerated to a second rotating speed V2 to rotate. The roller is controlled to rotate at different rotating speeds along with changes of the temperature in the roller, the drying degree of clothes and the like, and safer and more efficient drying is achieved.

Description

technical field [0001] The invention belongs to the technical field of drying equipment, and in particular relates to a control method of a clothes dryer. Background technique [0002] There are two heating modes of the clothes dryer in the prior art, namely, an electric heating clothes dryer and a heat pump clothes dryer. Among them, the electric heating dryer heats the ambient air into dry and hot air at an appropriate temperature, and the dry and hot air flows through the surface of the clothes to take away the moisture evaporated from the wet clothes, so as to realize the rapid drying of the clothes; the heat pump clothes dryer mainly compresses The machine heats the circulating air to dry the laundry. [0003] Among them, the first type of electric heating dryer has a short drying time, but the heating temperature is high. During the heating process, it will not only consume a lot of electricity, but also may damage the fibers of the clothes, affect the user experience...

AI Technical Summary

Problems solved by technology

[0003] Among them, the drying time of the first electric heating type clothes dryer is short, but the heating temperature is high, which not only consumes a lot of electric energy during the heating process, but also may damage the fibers of the clothes, affect the user experience, and cause the clothes to dry. Uneven drying, local overheating and even fire

Although the second type of heat pump dryer consumes less power and has a low heating temperature, it will not damage the fibers of the clothes during heating, but the drying process requires heat conduction between the air and the refrigerant, resulting in a long drying time. And the circulating air needs to pass through the heat exchanger, which will increase the wind resistance, so the drying efficiency of the heat pump system is low, and the heat pump dryer also has the problem of uneven heating

However, during the drying process, the drying cylinder is in a state of high-speed rotation, and the clothes will always be close to the wall of the cylinder. If heated for a long time, it may burn the clothes, cause damage to the fibers of the clothes, and affect the user experience.
