Abstract

PROBLEM TO BE SOLVED: To dry clothing and the like required a long period of time conventionally within a shorter period of time than the time required by a conventional drying machine, by a method wherein an air pressure in a drum with the clothing and the like therein is increased sand decreased. SOLUTION: Clothing and the like to be dried are charged into a drum 2 through the take-out port 6 of the same and a lid is closed surely. Thereafter, the drum 2 is turned into the direction 5 until the clothing and the like are taken out of the drum. Dried warm-air is charged sufficiently into the drum 2 through an air intake port 4, then, regulating valves at the air outlet port 1 and the air intake port 4 are closed to seal dried and warmed air into the drum 2. Subsequently, a device 3 is moved forward and rearward to repeat the pressurizing and evacuating of the air in the drum 2. Thereafter, the regulating valves at the air outlet port 1 and the air intake port 4 are opened to discharge air containing moisture through the air discharging port 1 while introducing dried warm-air through the air intake port 4. When the air in the drum 2 is displaced in some degree, the valves at the ports 1, 4 are closed and the device 3 is moved forward and rearward to repeat the pressurizing and evacuating of the air in the drum 2. These operations are repeated until the clothing and the like are dried sufficiently and, thereafter, the rotation 5 of the drum 2 is stopped to take out the dried clothing and the like through the take-out port 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

In a dryer for drying clothes and the like, dry and warm air is fed into a drum containing clothes and the like for the purpose of drying, and the air is pressurized and decompressed to increase or decrease the density of the air. By repeating this, the density of the air contained between the fine fibers such as clothes in which the air is hard to move repeatedly increases and decreases. That is, the volume of each air repeatedly increases and decreases, and a movement can be created in the air between the fibers. By this, the fine fiber and the water sandwiched between the fiber are pushed out of the fiber, and at the same time, the dried and warm air is easily taken in between the fine fiber such as clothes and the fiber, so that the drying is accelerated. .

Conventionally, a dryer for drying clothes and the like blows dry warm air into a rotating drum to dry clothes and the like. With this alone, the air between the fine fibers such as clothes was difficult to move, and it took a long time to dry the clothes.

[0003] The present invention blows dry warm air into a rotating drum, and at the same time, applies pressure and pressure to the air in the drum to increase or decrease the density of the air in the drum, thereby making clothes such as clothes. It makes it easy to move hard air between fibers. After repeating this several times, the moist air is discharged. After that, freshly dried hot air is blown into the drum, and the air in the drum is pressurized and reduced as before, and the moist air is discharged. By repeating this process many times, the clothes are dried quickly.

[0004] By doing so, the drying of clothes and the like, which required a long time, can be greatly reduced, and it is economical.

Further, the present invention is applied to a dehydrator for clothes and the like utilizing centrifugal force to facilitate the dehydration of clothes and the like. Thereby, dehydration becomes possible without applying a strong centrifugal force, and fibers such as clothes can be hardly damaged.
