Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer, and more particularly to a clothes dryer intended to improve drying performance.

First, a conventional clothes dryer will be explained.

FIG. 1 is a side sectional view of a conventional clothes dryer. In this FIG. 1, an exhaust port 7 for discharging humid air containing moisture evaporated from the clothing 10 from the drum 1 to the outside of the machine is connected to a fan 8 as shown in FIG.
It is provided near the rotation center of the drum 1 of the fan casing 6 that houses the fan casing 6. For this reason, drum 1
The hot air heated by the heater 3 flows into the drum 1 from a large number of hot air inlets 5 bored at the bottom of the circumference of the drum in the heater duct 2 on the front side of the drum.
The hot air A flows from the bottom of the drum 1 toward the center of the exhaust side plate 1b of the drum 1, but the hot air A flows through the bottom of the drum 1 and comes into good contact with the clothes 10, while the hot air A flows through the top of the drum 1 without coming into contact with the clothes 10. Because of this passing hot air B, the humidity of the air discharged from the drum 1 to the outside of the machine is low, and the thermal efficiency (i.e., the amount of heat used for water evaporation/heater) is low. The disadvantage was that the amount of heat used) and drying performance were poor, and the drying time was therefore prolonged.

Note that 1a is a side plate on the intake side of the drum 1, 4 is a door, and 9 is a motor that drives the drum 1 and the fan 8.

The present invention eliminates the above-mentioned drawbacks of the prior art,
It is an object of the present invention to provide a clothes dryer in which hot air is brought into sufficient contact with clothes in a drum and has high thermal efficiency and drying performance.

A feature of the present invention is that a drum for storing clothes to be dried is horizontally stored in an outer frame, and the drum is rotated at a low speed to agitate the clothes.
In a clothes dryer that dries clothes by sending hot air heated by a heater into the drum and exhausting humid air containing moisture evaporated from the clothes from inside the drum to the outside using a fan, the outer periphery of the dryer is The clothes dryer is equipped with an exhaust side plate of the drum that is slidably supported at the bottom, a number of exhaust ports formed at the bottom of the drum, and an exhaust duct that is fixed to the outer frame or fan casing.

The present invention will be explained below with reference to Examples.

FIG. 2 is a side sectional view of a clothes dryer according to an embodiment of the present invention, and FIG. 3 is a view taken along the - arrow in FIG.

In Fig. 2, 11 is an outer frame, 12 is a drum,
12a is a side plate on the intake side of the drum 12; 12b is a side plate on the intake side of the drum 12;
The exhaust side plate 12c is provided in the drum 12 and includes a lifter (see FIG. 3) that stirs the clothes 30;
13 is a heater duct fixed to the front surface of the drum 1 within the outer frame 11; 14 is a heater provided within the heater duct 13; 15 is a heater duct 13
, a large number of hot air inlets bored at the bottom of the circumference of the drum, 16 a door for putting in clothes attached to the front surface of the outer frame 11, 17 a fan casing, 18
is a fan stored in the fan casing 17,
19 is an ear portion 19a on the outer circumference of the drum 1.
This is an exhaust duct that slidably supports the exhaust side side plate 12b of No. 2, and has a number of exhaust ports 20 bored in its lower part, especially in the lower part from the drum rotation center,
This exhaust duct 19 is fixed to the fan casing 17. Therefore, regardless of the rotation of the drum 12, the exhaust port 20 is always located in the lower part of the drum 12. 31 is a bearing sleeve attached to the center of the duct 19, and 18a is a fan shaft fitted into the bearing sleeve 31.

21 and 22 are the intake side side plates 1 of the drum 12;
2a and the heater duct 13, and the drum 12
Felt 23 slides between the exhaust side side plate 12b and the exhaust duct 19 to maintain airtightness, and 23 is the fan shaft 1.
A fan pulley is attached to 8a, 24 is a motor, 25 is a motor pulley attached to the shaft of the motor 24, 26 is a drum pulley for rotating the drum attached to the motor shaft, and 27 is attached to the outer frame 11 near the motor 24. Outside air intake port, 28 is fan pulley 23 and motor pulley 25
Fan belt hung between, 29 is drum 1
A drum belt 30 is hung between the circumferential portion of 2 and the drum pulley 26, and 30 is clothing.

Next, the operation of the embodiment configured as described above will be explained.

When the motor 24 and heater 14 are energized, the fan 18 rotates at high speed and the drum 12 rotates at low speed. By the fan 18, outside air enters the outside frame 11 through the outside air suction port 27 of the outside frame 11, is heated by the amount of heat generated by the motor 24, is guided to the heater duct 13, and is further heated by the heater 14. The hot air passes through the heater duct 13, flows into the drum 12 from the hot air inlet 15, takes away evaporated moisture from the clothes 30 within the drum 12, and exits the drum from the exhaust port 20 of the exhaust duct 19. The humid air is then exhausted to the outside of the machine through the fan casing 17.

In this case, the hot air inside the drum 12 flows from the hot air intake port 15 provided at the lower part of the heater duct 13 on the front surface of the drum toward the exhaust port 20 provided at the lower part of the exhaust duct 19 on the rear surface of the drum. Drum 12 passes through the lower part of drum 12 and falls naturally.
It makes sufficient contact with the clothes 30 gathered at the lower part of the dryer, and the amount of heat heated by the heater 14 can be effectively used for drying the clothes 30.

Although the exhaust duct 19 is fixed to the fan casing 17 in this embodiment, for example,
The ear portion 19a of the exhaust duct 19 may be extended to the right (in FIG. 2) and fixed to the outer frame 11.

According to the embodiment described above, the hot air is always made to flow through the lower part of the drum 12 within the drum 12, so that the hot air is brought into sufficient contact with the clothes 30 that have collected at the lower part of the drum 12 due to natural falling. This also reduces the amount of hot air that passes through the drum without coming into contact with clothing, which is the case in the past.
The dry air discharged from the dryer can be vented after increasing its humidity, improving thermal efficiency and drying performance, thereby shortening drying time and saving power.

As described above in detail, according to the present invention, a drum for storing clothes to be dried is horizontally stored in an outer frame, and the drum is rotated at low speed to agitate the clothes, and the drum is rotated at a low speed to agitate the clothes. In a clothes dryer that dries clothes by sending heated hot air into the drum and exhausting humid air containing moisture evaporated from the clothes from inside the drum to the outside using a fan, The side plate on the exhaust side of the drum is slidably supported, a number of exhaust ports are drilled at the bottom of the side plate, and an exhaust duct is fixed to the outer frame or fan casing. It is possible to provide a clothes dryer that has sufficient contact with the dryer and has high thermal efficiency and drying performance.
