Abstract

PURPOSE:To eliminate the part where cotton dusts are taken and piled and prevent the generation of smoke, fire, and odor by installing an inverted U-figure shaped heater along a guide plate in the vicinity of the inner peripheral wall part of an inverted U-figure shaped drum guide plate whose lower part and the drum surface side are opened. CONSTITUTION:A cylindrical door port 4 is installed towards a drying drum 3 from a door 2, and a guide plate 6 for guiding hot air to a drum suction port 5 is installed onto the concentric outer periphery of the door port 4, and a bearing 7 for supporting the drum 3 is installed at the top edge of the inner periphery of the guide plate 6. Inside the guide plate 6, an inverted U-figure- shaped sheath heater 8 is installed, and fixed by a heater fixing metal fitting 9. The guide plate 6 is formed into an inverted U-figure-shaped box shape whose lower part is opened. Therefore, the part where cotton dusts are piled is removed, and the thread trash and the cotton dusts which flow reversely from the drum 3 are dropped directly into the lower part inside the body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a clothes dryer, and particularly to a structure that prevents lint and fluff from accumulating near the heater.

[Conventional technology]

In the conventional configuration, the heater is loop-shaped and the lower part of the guide plate is open, as shown in Fig. 3. In this configuration, cotton dust does not accumulate on the lower loop heater-shaped portion or the lower rising portion of the guide plate. It has the disadvantage that it accumulates.

[Problem to be solved by the invention]

The above conventional technology does not take into consideration the accumulation of cotton dust that flows back from the drum, and the accumulated cotton dust grows.
There was a problem of smoke, fire, and odor coming from contact with the heater.

In order to prevent smoke generation, ignition, and odor generation, the present invention provides a structure in which cotton dust flowing back from the drum is difficult to accumulate and grow.

[Means to solve the problem]

The purpose is to eliminate cotton dust by incorporating an inverted U-shaped heater along the guide plate near the inner peripheral side wall of the drum guide plate, which has an inverted U-shaped box shape with the lower part and the drum surface side open. This is achieved by allowing the parts that get caught and accumulate to fall directly to the bottom of the main body.

〔Example〕

Embodiments of the clothes dryer according to the present invention will be described below with reference to the drawings.

In FIG. 2, a door 2 is provided at the front of the outer frame 1 to take in and take out dried materials, and a cylindrical door boat 4 is provided from the door 2 toward the drying drum 3.

A guide plate 6 for guiding hot air to the drum intake port 5 is provided on the concentric outer circumference of the door port 4, and a bearing 7 for supporting the drum 3 is attached to the inner circumferential tip of the guide plate 6.

An inverted U-shaped sheathed heater 8 is provided inside the guide plate 6 and is fixed by a heater tab 9.

A fan 11 is installed at the rear of the outer frame 1 and rotates by the power of a motor 10 to pressurize the inside of the outer frame 1 and send hot air to a drum intake port 5 provided on the front side of the drum 3. Further, a timer 12 for controlling drying time is provided at the lower front of the outer frame 1.

An exhaust port 13 is provided at the rear of the drum 3, a bearing metal 14 is attached to the center of the rear, and the drum 3 is configured to be freely rotatable around a shaft 15 provided on the drum 3. On the inside of the rear surface of the drying drum 3 is a synthetic resin filter mounting shaft 1.
6 is attached to the drum 3 by an integrally molded claw part, and a filter 1 is attached to the front part of the drum 3 to remove thread waste from dried materials.
7 is inserted.

A thermostat 18 for preventing excessive temperature rise and a temperature fuse 19 are fixed to the upper part of the guide plate 6 with screws.

By closing the door 2 and setting the timer 12, the motor 10 rotates, and the fan 11 fixed to the motor shaft rotates.

On the other hand, the drum 3 also has a pulley 20 that decelerates the rotation of the motor 10.
■The belt 21 hooked on starts rotation via the idle pulley 22.

The cold air sucked in by the air intake port 23 and generated by the fan 11 pressurizes the inside of the outer frame 1 and becomes hot air by passing through the guide plate 6 containing the heater 8, and then flows through the drum air intake port 5 on the front surface of the drum 3. Go inside drum 3.

The hot air that has completed heat exchange with the dried material in the drum 3 passes through the filter 17 and then through the drum discharge port 23 provided at the rear of the drum 3, fixes the bearing metal 14, and then passes through the outer frame 1. F beam 24 and outer frame 1 attached to the rear
It passes through the flow path formed by the air and is discharged outside from the exhaust port 13.

Next, points related to the present invention will be explained with reference to FIG. 1st
The figure shows a configuration diagram of the guide plate 6 and heater 8, which are central to the present invention, and corresponds to the figure when the drum is removed from the rear of the main body (the outer frame is omitted from the figure). U-shaped heater 8 (a sheathed heater is used in this example)
is built into the guide plate 6. The guide plate 6 has an inverted U-shaped box shape with an open bottom.

This is to prevent thread waste from accumulating in the vicinity of the heater 8, and the inverted U-shape of the heater 8 also has the same effect.

That is, the intake port 23 is clogged with dust in the air,
Or if the filter in number 17 is clogged or the exhaust port in number 13 is blocked by a wall, etc.

The flow of air becomes poor, and a phenomenon occurs in which lint and fluff generated from the dried material in the drum 3 flow back from the drum intake port 5. In this case, in the conventional configuration, thread waste easily accumulates not only in the vicinity of the heater but also in the terminal part of the heater (■) shown in FIG.
There was a possibility that the lint accumulated on the heater 8 would grow and touch the heater 8, causing smoke and ignition.

In the conventional example shown in FIG. 4, the accumulation of cotton dust similarly occurs at 0 parts or 0 parts.

In the present invention, the lower rising part of the guide body 6, which is a drawback of the conventional example, is abolished, and the heater 8 is formed into an inverted U-shape, thereby eliminating the part where fluff accumulates, and eliminating the thread waste flowing back from the drum 3.
It has a structure that allows cotton dust to fall directly into the lower part of the main body.

〔Effect of the invention〕

As described above, according to the present invention, the lower part of the heater is removed.

The removal of the raised part at the bottom of the guide plate creates a structure that makes it difficult for cotton dust to accumulate from the drum, causing smoke.

To provide a dryer with excellent stability without worrying about ignition, odors, etc.
