The present invention relates to a laundry machine, and more particularly to a drum type laundry dryer for easy repair and maintenance.
2. Discussion of the Related Art
Generally, a dryer is an electric home appliance for drying wet laundry that has been washed using hot air.
The dryer includes a drum for accommodating articles to be dried, a driving source for driving the drum, a heating unit for heating air introduced into the drum, a blower unit for sucking or discharging air inside the drum, and the like.
The dryers may be classified into an electric dryer and a gas-type dryer according to a method for heating air, that is, a heating unit. The electric dryer heats air using electric resistance heat. The gas type dryer heats air using heat generated by gas combustion.
In another way, the dryers may be classified into a condensation dryer and an exhaust dryer. In the condensation dryer, humid air which has been heat-exchanged with the articles to be dried in the drum is circulated without being discharged to the outside, and the humid air is converted into condensed water in a separate condenser by heat exchange with outside air to be discharged to the outside. In the exhaust dryer, humid air which has been heat-exchanged with the articles to be dried in the drum is directly discharged out of the dryer.
In yet another way, the dryers may be classified into a top-loading dryer and a front-loading dryer according to the manner of loading the articles to be dried into the dryer. In the top-loading dryer, the articles to be dried are loaded from the upper side of the dryer. In the front-loading dryer, the articles to be dried are loaded from a front surface of the dryer.
The above-mentioned conventional dryers have the following problems.
When a problem occurs in the heating unit for supplying hot air, an operation for disassembling a cabinet forming an external appearance of the laundry dryer should be performed to check and solve the problem. Also, after the problem of the heating unit is checked and solved, an assembly operation should be performed to arrange the cabinet at an original position.
Further, the disassembly and assembly operations of the cabinet should be repeated whenever the problem of the heating unit occurs, thereby causing a trouble in the operation. Particularly, the disassembly and assembly operations of the cabinet are not easy in a public place such as a commercial laundry room. It also causes inconvenience to the users who use the commercial laundry room and it is undesirable in the aspect of appearance.
