Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure of a clothes dryer having a heat exchange type fan, circulating air in a drum, condensing, replacing water, and discharging the water. The present invention relates to improvements in clothes dryers with a focus on productivity, repair service, and handling of lint filters.

[Conventional technology]

 The drying method of the clothes dryer is roughly classified into the following two methods.

(1) One is a method in which a simple fan is used as a fan, and moisture in the circulating air is removed by a dedicated heat exchanger installed in the middle of the circulating duct.

However, according to this method, a special heat exchanger is required for drying clothes, and the product cost cannot be denied.

(2) Another method is to use a heat exchange type fan (a so-called front and back wing fan) as the fan.

According to this method, the cost of the product can be reduced because a dedicated heat exchanger is not required as compared with the method (1).

FIG. 2 shows a conventional general-purpose clothes dryer using a heat exchange fan as the fan.

As shown in FIG. 2, a heating element 5 for generating warm air is installed in front of a drum 3 for storing clothes, and the drum 3
A fan 6 is installed on the rear side of the fan, and the wind generated by the fan 6 is applied to the drum 3 → the yarn waste filter 14 → the fan casing.
13 → circulation duct 9 → heating element 5 → drum 3

[Problems to be solved by the invention]

In this case, the heating element 5 is attached to a drum support 17 that carries a bearing in front of the drum 3, and the fan 6 and the fan casing 13 are attached to the support 12. The drum support 17 is fixed to the outer frame front plate 1-1.

And had been split into. Also, in order to simplify the repair service after the main body is installed, the outer frame body front plate 1-1 can be detached from the outer frame body 1 so that the work can be performed from the front side of the main body. In addition, the heating element 5 must be removed together, and a complicated operation is required in the configuration such as connection and binding inside the main body that is entangled with the heating element 5.

Further, in the configuration shown in FIG. 2, the lint filter 14 is installed at the back of the drum 3 with respect to the door 2 through which clothes are taken in and out, and it is inconvenient to remove and attach it during cleaning or the like.

On the other hand, in addition to the above configuration, a heating element for generating hot air, a fan, and a lint filter are installed at the rear of the drum. → Some drums circulate the air between the drum and the drum. However, in this case, the circulating air does not flow through the depth of the drum and the warm air does not uniformly hit the clothes, so that the drying operation cannot be performed efficiently. This becomes more remarkable as the depth dimension of the drum increases as the capacity of the clothes dryer increases.

An object of the present invention is to provide a clothes dryer having a heat exchange type fan, which circulates air in a drum, condenses and replaces it with water, and discharges all of the productivity, repair service, and handling of lint filter. It is an object of the present invention to provide an improved and improved clothes dryer.

[Means for solving the problem]

Said object is a clothes dryer for drying clothes by supplying warm air to a rotating drum in which clothes are stored, and a fan for supplying warm air circulates air inside the drum on the front and back, On the other hand, in a clothes dryer that draws in outside air, performs heat exchange between the front and back of the fan, condenses the moisture of the circulating wind, and discharges it as water to the outside of the machine, the door side for putting clothes in and out of the drum is the front of the drum. In this case, in addition to installing a heating element and a fan in the direction of the drum for generating warm air, a lint filter for collecting lint generated from clothes in the drum is further provided in front of the drum and This is achieved by being detachably mounted on the drum support in front of the circulation wind discharge port of the drum, and facing the inside of the drum.
