Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dryer that captures lint and the like contained in the exhaust gas from a rotating drum by passing the exhaust gas through a filter.

Conventionally, when a dryer is in operation, a lot of lint and dust is scattered from the items to be dried, especially clothes, and in order to prevent this from flowing out of the machine (indoors) with the exhaust flow, it is generally done at the exhaust port. Filters that capture lint are essential for dryers, but these filters also have a limited capture capacity, and there is a risk that a certain amount of lint may be captured, causing so-called clogging. If this happens, the filter must be removed and the trapped material removed so that the blockage does not obstruct the exhaust flow.

However, this filter is attached to the front of the exhaust hole at the rear of the rotating drum inside the dryer, and when removing captured material, it is necessary to remove the filter by inserting your hand through the clothes opening formed at the front of the rotating drum. Especially in a so-called laundry type dryer where the dryer is located at a high place, there is a drawback that the task of removing the filter becomes increasingly difficult.

The present invention has been made in view of the above circumstances, and its purpose is to provide a first exhaust path for guiding the exhaust from the rotating drum disposed inside the outer box to the front side, and a first exhaust path for guiding the exhaust from the rotating drum disposed inside the outer box. A second exhaust path for guiding the air to the rear side is provided, and a filter device comprising a case and a filter dividing the case into two chambers is installed in a filter storage chamber communicating with both the first exhaust path and the second exhaust path. By making the outer box reversible 180 degrees and detachable from the front side, the filter device can be easily attached and detached from the front side of the outer box when removing captured objects such as lint. To provide a dryer that does not impair its capturing ability even if it is installed without regard to the relationship.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

It is discharged to the outside through an exhaust passage 33.

35 is a filter device, which is the filter housing chamber 34;
The outer box 1 is reversible by 180 degrees and can be attached and detached from the attachment/detachment opening 1a of the outer box 1, and this will be described below.

36 is a case forming the main body of the filter device 35;
This has a cylindrical shape with only the rear end open as described below.

Reference numeral 37 denotes a knob formed in the horizontal direction at the center of the front surface of the front closing wall 36a of the case 36, and on this knob 37, the characters ``1 lint file cuyo'' are displayed in horizontal writing.

Reference numeral 38 denotes a locking groove formed on the back surface of the front blocking wall 36a of the case 36, which is located at a position corresponding to the knob 37.

39, 39 are ventilation holes bored in the rear end wall 36b of the case 36, and these ventilation holes 39, 39 are respectively connected to the first
The exhaust passage 32 and the second exhaust passage 33 are connected to each other.

Reference numeral 40 denotes a locking hole formed in the center of the rear end wall 36b of the case 36 and long in the horizontal direction.

Reference numeral 41 denotes a filter, which consists of a substantially rectangular frame 41a and a filter portion 41b integrally formed so as to extend over the frame 41a.

The filter 41 is inserted into the case 36 through the locking hole 40 so that the front end of the frame 41a is connected to the locking groove 3.
8 and the rear end is locked in the locking hole 40, so that the inside of the case 36 is partitioned into a first chamber 36c and a second chamber 36d.

Note that the filter 41 is removable from the case 36.

Next, the operation of this embodiment with the above configuration will be described.

Now, the front door 4 is opened and the clothes are thrown into the rotating drum 8 through the clothes entrance 2.

Then, after closing the door 4, a timer (not shown) is set using the timer operation knob 42.
4 and the electric heater 17 are energized.

Then, the rotary drum 8 is rotated via the belt 26 by the rotational drive of the drive motor 24, and the fan 20 is rotated via the belt 28.

At this time, the air sucked in through the small hole of the cover 6 attached to the intake port 5 by the operation of the fan 20 is transferred to the intake duct 1.
6 , where it is heated and hot aired by an electric heater 17 and sucked into the rotating drum 8 through the intake hole 13 .

While drying the clothes by removing moisture from the clothes, the hot air is sucked into the casing 10 from the ventilation holes 18 located below, and a part of it is returned to the rotating drum 8 from the ventilation holes 18 located above. as shown by arrow B1, and most of it passes through the intermediate duct 29 to the first
It is discharged as exhaust gas into the exhaust passage 32 of.

Such exhaust gas is passed through the filter device 3 through the first exhaust path 32.
5 into the second chamber 36c through the lower ventilation hole 39, and then passes through the filter 41 from below to the upper side to enter the second chamber 36d, from where it flows through the upper ventilation hole 39 into the second chamber 36d. It is discharged to the exhaust passage 33 of.

At this time, the lint and the like contained in the exhaust gas are removed from the filter section 41.
It is captured by passing b.

Now, to remove and clean the lint and the like captured in the filter section 41b, the filter device 35 is removed from the front of the outer box 1 and the filter 41 is removed from the inside of the case 36.

The filter 41 that has been cleaned in this manner is reinserted into the case 36 and the case 36 is re-inserted into the filter housing chamber 34.
It is attached by inserting it into the interior through the attachment/detachment opening 1a.

Next, a case where the dryer having the above structure is placed above a washing machine and used as a so-called laundry type will be described with reference to FIG. 4.

Reference numeral 43 denotes a stand on which a washing machine 44 is disposed on the lower stage, and on the upper stage of this stand 43, the main body of the dryer of this embodiment is placed upside down so that the timer operation knob 42 can be easily handled.

In this case, in order to prevent the character 1 lint filter displayed on the knob 37 of the filter device 35 from being upside down, the filter device 35 should be installed with the filter device 35 reversed 180 degrees with respect to the main body of the dryer. good.

As described above, the present invention can obtain the following effects.

In other words, since the filter device can be attached and detached from the front side of the outer box, it is easy to attach and detach when removing and cleaning trapped substances such as lint, whether the dryer is normally installed or installed at a high place as a laundry type. , its cleaning work becomes easier.

Further, the filter storage chamber communicates with both the first and second exhaust passages, and the filter device has two chambers in which the filters are disposed, each of which is connected to the second and second exhaust passages, respectively. Since the filter device is configured to communicate with the road, there is no directionality when installing the filter device. Therefore, even if the dryer is installed upside down, the filter device can be installed with the display characters etc. matching the orientation. It is possible to provide a dryer that does not cause any particular difference in the performance of capturing lint etc. no matter which direction it is installed.
