Description

Laundry drying machine, sidewall of which is open}

The present invention relates to a laundry dryer for drying a laundry cleaned using organic solvents or water, and more particularly, a flow of warmth in a dryer case flows from top to bottom by a pneumatic difference. By opening one or more sidewalls, the sidewalls are convenient for ease of use, such as placing laundry inside the case and making it easier to remove. Also, the sidewalls can be reduced in production cost, transportation cost, and production time. It is about a laundry dryer.

In general, the organic solvent refers to a liquid capable of dissolving other substances, and is widely used as a solvent in laundry dryers and various printing related companies.

In the laundry, clothes that cannot be washed using water are washed with organic solvents. After the washing operation, the organic solvents contained in these laundry are removed from the dryer.

The inventors of the present invention, as shown in Figures 1 to 3, the drying chamber 30 configured to mount the laundry therein, the air suction grill 11 configured on the upper surface of the drying chamber 30, the air suction grill 11 ) Is located at the lower side of the heat sink 20 is installed in the upper upper end of the drying chamber 30, the propeller 23 is installed to be rotatable in the lower portion of the heat sink 20, and the lower side of the drying chamber 30 Has developed a laundry dryer consisting of a blower 50 is installed in the compartment 40 configured in the filing of the patent application No. 2007-0107175.

Both ends of the hanger 31 hang on an upper surface of the support 34 on which the hanger 31 is inserted, and a plurality of hanger recesses 34a having a constant width are continuous in the longitudinal direction. Since the hanger 31 is hooked up to the hook recess 34a at any position of the both side supports 34, the hanger 31 can be hanged.

When the boiler is operated in this state, hot water supplied from the boiler flows into the heat dissipation pipe of the radiator 20 through the hot water supply pipe 21, and the external air is heated by the hot water.

Then, when the laundry dryer is operated, the blower 50 is operated while clean air from the outside passes through the radiator 20 through the air suction grill 11, and the air passing through the radiator 20 is heated. The heated heat enters the drying chamber 30 to dry the laundry 35 hanging on the hanger 31.

The propeller 23 is to distribute the air passed through the radiator 20 to the drying chamber 30 while being evenly distributed and the laundry 35 is efficiently dried due to these vortices.

The exhaust gas containing the organic solvent removed from the laundry 35 dried with the heat drying the laundry 35 enters into the lower compartment 40 through the filter 41 and is discharged through the discharge pipe 51. .

When the laundry is washed with an organic solvent, the discharged gas goes to a cooler (not shown), and after cooling, goes to an organic solvent recovery machine (not shown) to recover the organic solvent. The recovered organic solvent is recycled, and the air from which the organic solvent is recovered is purified by a secondary treatment device and discharged to the outside.

In the case of laundry washed with water, since no harmful substances are included in the discharged air, the laundry is discharged to the outside without undergoing a post-treatment process.

On the other hand, foreign matter such as dust contained in the air passing through the drying chamber 30 is filtered by the filter 41, when the foreign material filtered by the filter 41 accumulates more than a predetermined amount to open the door 12 of the dryer Then, when the filter 41 is pulled toward the front, foreign bodies on the filter 41 are piled up to the rear of the filter by a brush 33 which is in contact with the upper surface of the front of the filter 41, using a hand or a tool. When the filter 41 is pushed backward, foreign bodies that could not be removed are pushed toward the front of the filter 41 and accumulated in front of the filter, which are removed again by using a hand or a tool.

Thus, the laundry dryer of the present invention is configured to dry the laundry 35 by the heat flowing in the vortex with a constant temperature in the state in which the laundry 35 is left in the drying chamber 30. Therefore, the dryer of the present invention exposes the entire surface area of the laundry to the flowing heat, and the drying speed is increased accordingly, and all parts are uniformly dried since the laundry is not entangled. Therefore, wrinkles are not generated in the laundry after drying.

In addition, the laundry 35 is dried in a state where it is settled in the drying chamber 30, so that the laundry 35 is not impacted, thereby causing damage such as breakage of a button attached to the laundry or dropping of cloth. It does not occur.
