Clothing dryer and washer dryer

Abstract

The invention provides a clothing dryer and a washer dryer. The clothing dryer is provided with: a first air flow path (9) having a first discharge opening (8) open at the rear of a drum (1) for containing clothing; and a second air flow path (11) having a second discharge opening (10) which is open at the front of the drum (1) and has a smaller cross-sectional area of air passage than the first discharge opening (8). The first air flow path (9) and the second air flow path (11) are selectively switched between each other in the middle of a drying process on the basis of the result of detection by temperature detection sections (71, 72) for detecting the temperature of drying air before and after the drying air makes contact with the clothing. When the first air flow path (9) has been selected, drying air having a greater volume than drying air provided when the second air flow path (11) has been selected is discharged from the first discharge opening (8), and when the second air flow path (11) has been selected, drying air having higher pressure and higher speed than drying air provided when the first air flow path (9) has been selected is discharged from the second discharge opening (10).

Description

technical field [0001] The present invention relates to a clothes dryer for drying clothes and a clothes dryer with washing function and clothes drying function. Background technique [0002] In the past, drum-type clothes dryers or laundry dryers sent drying air into the drum through an air duct, made the drying air come into contact with the clothes put into the drum to dry the clothes by depriving the clothes of moisture, and The air path outside the drum discharges the moisture-containing and high-humidity drying air. In particular, since clothes are dried in a limited and narrow drum space, there is a problem that clothes after drying are severely wrinkled, and various methods have been proposed to solve this problem. (For example, refer to Patent Document 1). [0003] Figure 11 A conventional drum-type washing and drying machine described in Patent Document 1 is shown. As shown in the figure, in the conventional drum-type washing and drying machine, in the drying p...

Problems solved by technology

[0004] However, according to the above-mentioned conventional structure, high-pressure and high-speed air is blown to the clothes 124, but usually in order to blow out the same air volume at a higher pressure and high speed, the amount of work will increase accordingly, so the power consumption of the motor for the blower fan increases.

In addition, according to the above-mentioned conventional structure, in order to increase the air volume blown to the inside of the rotary drum 123, two motors for blowing fans are used, and the power consumption is further increased.

Therefore, the above-mentioned conventional drum-type clothes dryer has a problem in reducing power consumption as a structure for shortening the drying time or spreading out wrinkles.
