clothes dryer

Abstract

The invention discloses a clothes dryer, which includes a casing; an inner cylinder, which is rotatably arranged in the casing around its axis and has an air inlet formed on the bottom wall; and an outer cylinder, which is sleeved on the outside of the inner cylinder. , a predetermined distance is separated between the outer cylinder and the inner cylinder to define an air channel communicating with the air inlet between the outer cylinder and the inner cylinder, wherein the opening of the outer cylinder and the opening of the inner cylinder face the same side and the opening end of the outer cylinder is in contact with the inner cylinder. An air outlet is formed between the open ends, and the air outlet is connected with the inside of the inner cylinder and the air duct respectively; a door cover used to close the opening of the outer cylinder; a semiconductor refrigeration piece, the semiconductor refrigeration piece is located in the air duct and has a hot end face and a cold end face , wherein the hot end face is located outside the peripheral wall of the inner cylinder, and the cold end face is located radially outside the hot end face; an air circulation driver used to drive the air in the inner cylinder and the air circulation in the air duct. The clothes dryer of the present invention has a simple structure, good drying effect and low energy consumption.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a clothes dryer. Background technique [0002] In the existing clothes dryers, the straight discharge type, condensation type or heat pump type are often used for drying clothes. The in-line clothes dryer has a simple structure and is easy to implement, but the discharged high-temperature and high-humidity gas affects the environment, and the waste heat of the exhaust cannot be effectively utilized. The temperature of the cylinder is high during drying, and the heat dissipated outside belongs to energy loss, which increases the Energy consumption of an inline clothes dryer. The condensing clothes dryer belongs to the internal circulation air duct and does not exhaust gas, but it needs to set up a separate condensing device such as a condenser to cool the high-temperature and high-humidity gas. machine energy consumption.

AI Technical Summary

Problems solved by technology

The in-line clothes dryer has a simple structure and is easy to implement, but the discharged high-temperature and high-humidity gas affects the environment, and the waste heat of the exhaust cannot be effectively utilized. The temperature of the cylinder is high during drying, and the heat dissipated outside belongs to energy loss, which increases the Energy consumption of an inline clothes dryer

The condensing clothes dryer belongs to the internal circulation air duct and does not exhaust gas, but it needs to set up a separate condensing device such as a condenser to cool the high-temperature and high-humidity gas. machine energy consumption

The heat pump type is more energy-saving, but the structure of the heat pump is relatively complicated, and the design cost is high. It also cannot solve the energy loss of the high-temperature heat dissipation of the cylinder during drying, and also has the disadvantage of high energy consumption.

[0003] In addition, in the existing dryers, the air duct is basically a separate sub-component, which is placed outside near the drying drum. The air duct circulation path is long, the resistance is large, and it takes up a lot of space, and the noise is easy to radiate outward.

Circulation fans are often limited by space, and use small-diameter centrifugal impellers. In order to meet the drying air volume, the speed is set relatively high, and the power consumption and noise will be relatively high.
