Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dryer in which both an intake filter and an exhaust filter are disposed on the front surface of an outer box.

In conventional dryers, for example, an intake filter is provided at the front of the outer box, and an exhaust filter is provided at the center of the rear wall of the rotating drum. however,
With this conventional structure, the intake filter can be inspected and cleaned easily, but the exhaust filter is located at the back of the rotating drum, making it difficult to reach and making inspection and cleaning very troublesome.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a dryer in which both the intake filter and the exhaust filter can be easily inspected and cleaned.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an outer box, in which a horizontally elongated rectangular recess 1b is provided in the center of the front surface 1a;
A rectangular opening 2 is formed in the center of the recess 1b, and a side-opening door 3 is pivotally mounted in the opening 2. Reference numeral 4 denotes a drum support plate attached to the back side of the front part 1a, and a short cylindrical drum support part 4a is provided on the outer periphery, and the central opening 4b of this plate is connected to the circumference of the opening 2 through the sealing member 5. is fitted.
Reference numeral 6 denotes a cylindrical rotating drum with open front and rear surfaces, and its front opening edge is supported on the outer periphery of the drum support portion 4a via a bearing member 7. 4c
is a ring-shaped upright part formed by bending the drum support plate 4 so as to surround the drum support part 4a, and a seal 8 whose tip is in sliding contact with the front surface of the rotating drum 6 is attached here. Reference numeral 9 denotes a rear plate of the outer box 1, on which a bearing part 11a that supports the rear opening edge of the rotary drum 6 via a bearing member 10 is formed in a short cylindrical shape on the outer periphery and communicates with the interior of the rotary drum 6. Multiple ventilation holes 1
1b, the ventilation recess 11 and the fan case part 12, and the communication recess 13 which allows the fan case part 12 and the ventilation recess 11 to communicate with each other, are each recessed so as to open rearward. A cover plate 14 is attached to the rear plate 9 to cover the rear openings of the ventilation recess 11, the fan case part 12, and the communication recess 13. Reference numeral 15 denotes a motor located at the upper left of the outer box 1 and attached to the top plate 1c of the outer box 1. A connecting shaft 16 having a pulley portion 16a is directly connected to the rotating shaft of this motor. A fan 17 disposed within the fan case portion 12 is directly connected to the tip. 18 is a belt stretched between the pulley portion 16a and the outer periphery of the rotating drum 6; 19 is a tension pulley that applies tension to the belt 18;
20 is a heater disposed within the communication recess 13.
Now, 21 is an intake port located on the right side of the door 3 and formed in the recess 1b, which is located outside the upright part 4c of the drum support plate 4 and communicates with the inside of the outer box 1, and is located in the recess. A rectangular intake filter 22 that covers the front surface of the intake port 21 is attached to 1b. Reference numeral 23 denotes an opening formed in the recess 1b located on the left side of the door 3, which is located inside the drum support part 4a of the drum support plate 4; A plurality of ventilation holes 24 as exhaust ports are formed at positions corresponding to the holes 23 so as to communicate with the interior of the rotating drum 6. On the other hand, 25 is an exhaust port body as a mounting plate screwed to the left side of the door 3 in correspondence with the opening 23. This is formed, for example, by integral molding of plastic, and protrudes rearward from the opening 23. A cylindrical portion 26 whose rear end abuts the front surface of the drum support plate 4 is integrally molded.
Reference numeral 27 denotes an exhaust filter integrally formed with a mesh filter member 27a, and the substantially box-shaped frame portion 2 of this
The left end of 7b is integrally formed with the exhaust port body 25 via a thin self-hinge part 28, and the frame part 2
The exhaust filter 27 is made to face the front surface of the exhaust port body 25 by removably engaging a hook member 27c protruding from the right end of the exhaust port body 25 with a hooking hole 25a provided in the exhaust port body 25. Note that the front surface of the exhaust filter 27 and the front surface of the intake filter 22 are each formed into an inclined surface that faces rearward as the distance from the door 3 increases. Further, 29 is a seal attached to the outer circumference of the cylindrical portion 26.

Next, the operation of this embodiment configured as above will be explained. When the motor 15 and heater 20 are energized, the fan 17 is rotated and the belt 18 is
The rotary drum 6 is driven to rotate through the heater 20 and the heater 20 generates heat, and outside air is sucked into the outer box 1 through the intake filter 22 and the intake port 21, and the outer circumference of the rotary drum 6 flows through the inside of the outer box 1. along the fan case portion 12 as shown by arrow A in FIG.
After being hot-aired by the heater 20 in the communication recess 13, the rotary drum 6 is heated through the ventilation recess 11 and the ventilation hole 11b as shown by arrow B in FIG.
The hot air is supplied to the rotary drum 6 after removing moisture from the material to be dried, and then passes through the ventilation hole 24 and the exhaust port body 2.
5 and the exhaust filter 27 in order as shown by arrow C in FIGS. 3 and 4, and are discharged to the outside of the outer box 1, and in this way, the material to be dried is dried by hot air. During this drying operation, dust contained in the intake outside air is captured by the intake filter 22 and adheres to the front surface of the intake filter 22, and lint in the exhaust is captured by the exhaust filter 27 and attached to the front surface of the intake filter 22. Attaches to the rear surface.

In this embodiment configured in this manner, the intake filter 22 and the exhaust filter 27 are provided on the front surface 1a of the outer box 1 in such a positional relationship as to sandwich the door 3. Inspection and cleaning of the clogged state of dust and lint can be performed only from the front of the outer box 1, and inspection and cleaning can be easily carried out, and both the intake filter 22 and the exhaust filter 27 can be checked. Since it is located in a position that is easily visible to the user, it is possible to prevent forgetting to inspect and clean it.

The fan 17 is located on the left side of the exhaust filter 27 in the outer box 1, and is located on the left side of the exhaust filter 27.
Since the air intake port 21 having the rotary drum 6 is positioned opposite to the air intake port 21 with the rotation drum 6 in between, the outside air taken in from the air intake port 21 passes around the outer periphery of the rotation drum 6 before being sucked into the fan 17. As a result, the power consumption of the heater 20 can be reduced accordingly, and the drying efficiency can be improved.

Furthermore, since the exhaust filter 27 is rotatably molded integrally with the exhaust port body 25 via the self-hinge portion 28, inspection and cleaning of the exhaust filter 27 is easy even though the surface on which lint adheres is the back side. can be easily done, exhaust filter 2
7 is integrated with the exhaust port body 25, so it can be prevented from falling off or being lost.

As is clear from the embodiments described above, the present invention connects an intake port to which an intake filter is attached and an exhaust port to which an exhaust filter is attached, such that the opening leading to the rotating drum is sandwiched between the door for opening and closing the opening. Since the filters are arranged on both sides, it is possible to provide a dryer in which both the intake filter and the exhaust filter can be easily inspected and cleaned.
