Description

Drying tunnel for fan of clothes dryer

Technical Field

The utility model belongs to the technical field of the dryer, in particular to dryer fan drying tunnel.

Background

Among various dryers, one that is more common includes an air circulation passage. The air circulation path includes a drying tunnel for heating air, a fan chamber for promoting air circulation in the circulation path, and a condensing chamber for condensing hot and humid air from the clothes drying drum. Air is heated by a heating device in the drying channel and then is sent into a clothes drying drum by a fan in a fan chamber, and hot air brings away part of moisture after contacting with damp clothes in the drum and enters a condensing chamber connected with the drum. Moisture in the air is separated from the air in the condensation chamber. The air with the moisture separated enters the drying tunnel again under the driving of the fan, and the air is circulated in a reciprocating way to gradually dry the clothes in the cylinder.

The heat utilization efficiency of the heating means in the drying tunnel is directly related to the energy consumption and drying speed of the dryer. Thus, the drying tunnel sealing performance is often very important. Meanwhile, the sealing performance of the fan room is also important because the fan room is directly connected with the drying tunnel.

At present, a common drying tunnel and a common fan room are constructed in a manner that the drying tunnel consists of a drying tunnel cover plate and a drying tunnel base, the fan room consists of a fan room cover plate and a fan room base, and four components are mutually butted. Because the butt joint is of a staggered structure, a solid sealing ring is difficult to arrange, and in order to seal the butt joint, the conventional method is to arrange rubber sealing rings between a drying tunnel cover plate and a drying tunnel base and between a fan room cover plate and a fan room base, but liquid sealant is adopted between the drying tunnel and the fan room to realize sealing.

However, the application of the sealant requires special gluing equipment, and the assembly accuracy and consistency are poor. The sealant takes a certain amount of time to cure. Moreover, as the drying tunnel is often in a high-temperature environment, the sealant is easy to emit harmful and healthy gas.

In chinese patent documents, there are a number of grant publication CN 202989611U, a grant publication date 2013.06.12, named: the technical scheme is that the clothes dryer with the drying channel and the fan chamber is adopted, the drying channel and the fan chamber are connected in an interconnected mode and are communicated in space, the drying channel comprises a drying channel cover plate and a drying channel base, a first sealing strip is arranged between the drying channel cover plate and the drying channel base, the fan chamber comprises a fan chamber cover plate and a fan chamber base, a second sealing strip is arranged between the fan chamber cover plate and the fan chamber base, a third sealing strip is arranged at the joint of the drying channel and the fan chamber, and the end portions of the first sealing strip and the second sealing strip are abutted to the third sealing strip.

However, the sealing rubber strip used in the technical scheme of the patent has the defects of easy aging, deformation, cracking and the like in the high-temperature environment of the drying tunnel, and cannot play an effective sealing role after a long time, so that the technical problem which needs to be solved currently is how to effectively avoid the aging of the rubber strip and improve the service life of the drying tunnel.
