Description

The present invention relates to a clothes dryer.

[Conventional technology]

When sticking a sheet that absorbs shock such as chucks to the inner surface of the drum, stick the sheet so that it covers the raised part such as a lifter that becomes the drying wing of the clothes, and the sheet of the raised part will be severely damaged, peeling and peeling The bumps must be retrofitted on the sheet because they have no surface. However, if there are a lot of post-projections, the percentage of the bumps hit by the protrusions increases, and the effect of the shock-absorbing sheet attached to the inner surface of the drum is reduced by half. Therefore, if you make the lifter which is the protrusion part small, you can not lift up the clothes,
Clothes roll and fall into a dumpling state, causing uneven drying. Therefore, looking at conventional competitors' products, the height of the lifter is reduced to one or two as in the past, so that the ratio of the lifter to the protrusion is reduced. However, if the number of lifters is small, the clothes lifted up by the lifters fall on the sheet and slide down the surface of the sheet, causing a slipping sound between the sheet and the clothes, so the configuration to reduce the number of lifters is also a cheek etc. The impact sound can be reduced, but the noise is not so much obtained because of the slipping sound.Therefore, in the case of sticking a sheet on the inner surface of the drum to absorb the impact sound,
Heretofore, there have been problems such as the fact that the structure does not have a raised structure that can effectively obtain a silent effect.

[Problems to be solved by the invention]

In the above-mentioned conventional technology, a sheet is attached to an inner peripheral surface of a drum to absorb a collision sound generated when a chuck or the like is agitated, and a clothes agitating blade (lifter) made of a plastic or the like attached later on the sheet is used. If the same size as before is provided with the same number of three, the ratio of tightening of the lifter increases, the ratio of tightening of the sheet decreases, and the impact absorbing sheet is not effectively utilized, and the effect cannot be obtained sufficiently. In addition, if the number of lifters is reduced to increase the ratio of the seats to be used effectively to reduce the number of lifters, the impact sound to the stirring blades such as chucks will be reduced, but it will fall to the sheets and scrape to the lifters. Because the period and time that can be raised is long, the clothing slips down on the sheet, which causes a rustling sound and a slip sound. The impact sound is considerably reduced and the effect on the impact sound is produced, but the secondary slip noise is produced. As a result, the sheet is not sufficiently used effectively for the silent sound with the conventional stirring blade (lifter) configuration.

An object of the present invention is to provide a clothes dryer that makes use of the effect of a sheet that absorbs shock noise such as chucks and is less likely to cause secondary noise such as slip noise.

[Means for solving the problem]

The invention provides a drum rotatably supported in a machine frame,
A clothes dryer provided with a shock-absorbing sheet made of a synthetic resin provided so as to cover the inner periphery of the drum, a heater and a fan for sending hot air into the drum, and an electric motor for driving the fan and the drum. In the inner circumference of the drum, one clothes stirring blade protruding higher than the surface of the shock absorbing sheet, and a plurality of non-slip protruding lower than the clothes stirring blade is provided, and the non-slip is It is formed so as to extend in the depth direction and is arranged at intervals in the circumferential direction of the drum, and the non-slip has a protrusion height of 10 mm from the surface of the shock absorbing sheet.
It is characterized by being set to not less than 20 mm.

[Action]

A shock absorbing sheet such as a chuck is provided on the inner peripheral surface of the drum, and one stirring blade and two slip stoppers are mounted on the sheet. By rotating the drum, the clothes are lifted and stirred by one stirring blade. Dry the clothes by hitting the clothes evenly with hot air.During the drying process, the clothes that have fallen to a place without stirring blades have the slipper stop so that the stirring blades rotate next without slipping the sheet. Since the clothes are lifted and stirred by the stirring blades, there is no problem such that the clothes are not stirred and become in a dumpling state to cause uneven drying.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. A back cover 2 is fixed to the rear surface of a metal machine frame 1. A clothing doorway 3 formed on the front of the machine frame 1 and a door 4 for opening and closing the doorway 3 are located on the front of the machine frame 1, and a metal annular drum support plate 5 fixed to the machine frame 1 and a machine frame A drum 7 serving as a drying chamber is rotatably supported by a rear bearing 6 arranged at the rear of the inside 1. On the inner peripheral surface of the drum, a shock absorbing sheet 25 made of a PP foam sheet t2 as a base material and made of a PP sheet t0.14 on the surface is used to absorb an impact sound generated when the chucks and buttons attached to the clothes 30 are stirred. It is stuck. Also, on the surface of the shock absorbing sheet 25, one clothes agitator lifter (clothing agitating blade) 26 and two clothes stoppers 27 are attached at 120 pitches so that the clothes 30 slip on the surface of the shock absorbing sheet 25 and do not slip. . A hot air outlet 8 composed of a number of holes is formed on the rear surface of the drum 7. A circulation path 10 is formed to communicate with a hot air inlet 9 formed below the drum supporting plate 5 from a vent 12 of a fan casing 11. A honeycomb heater 13 made of a positive temperature coefficient thermistor is provided opposite to the hot air inlet 9, and is housed in an L-shaped duct 14 fixed to the drum support plate 5. Juan casing
Heat exchange type double-sided fan 16 laid across 11
It is rotatably supported at 17 via metal. Machine frame 1
The drum 7 is rotated by a pulley including an idler pulley and a belt 24 by a motor 18 disposed in the upper portion, and the double-sided fan 16 is rotated by the pulley belt. A filter 19 attached from the inside so as to cover the hot air outlet 8 on the rear surface of the drum 7 is mounted. A cooling air inlet 20 is formed at the center of the back cover 2 and a cooling air outlet 21 is formed at the outer periphery. In the fan casing 11 facing the hot air outlet 8 provided on the rear surface of the drum 7, a humidity sensor 23 for detecting a change in the state of the air in the drum 7 is provided. Hereinafter, the operation will be described. In operation, first, the door 4 is opened, the dehydrated clothes 30 are stored in the drum 7, and when a power source (not shown) is turned on, the hot air of the drum support plate 5 is heated by the motor 18 and the heater 13 to become high-temperature dry air. Drum 7 from entrance 9
After the water contained in the clothing 30 is uniformly evaporated and applied to the rotating clothing 30, the temperature of the clothing 30 is increased to a high temperature and high humidity. After the waste cloth is collected by the filter 19, the hot air outlet 8 of the drum 7 It is sucked into the double-sided fan 16 in the fan casing 11. Here, the air is cooled to a temperature lower than the dew point by outside air, and condensed water is generated on the side of the circulation air passage of the heat exchange fan 16, and the condensed water is discharged from the drain port 15 of the circulation passage 10.

In this drying process, the clothes 30 are lifted up and stirred by the clothes stirring lifter 26 by the rotation of the drum 7. As shown in FIG. 2, the conventional product has a single lifter 26, so that the garment 30 is lifted up by the lifter 26, falls, and separates from the lifter 26. When it falls on the sheet 25, it slides on the absorbing sheet until it is lifted up by the lifter 26, and emits a slipping sound. FIG. 3 shows the construction of the present invention, but even if the garment 30 falls considerably forward of the lifter 26 in the direction of rotation of the drum 7 of the shock absorbing sheet 25, the garment 30 can be prevented from slipping by the slip stopper 27. Without slipping 25, it is stopped and lifted up by the next lifter 26 and stirred.

The slip stopper 27 will be described with reference to FIG. 4, FIG. 5, and FIG. Assuming that the height of the non-slip is a and the width is b and the length is c, the non-slip 27 is 10 (mm) ≦ a ≦ 20 (mm),
In addition, when the height a is not uniform as shown in FIGS. 5 and 6, the average of the heights between c is a.
And

〔The invention's effect〕

As described above, the present invention provides a drum rotatably supported in a machine frame, a synthetic resin shock absorbing sheet provided so as to cover the inner periphery of the drum, and sending hot air into the drum. A clothes dryer provided with a heater and a fan for driving the fan and the drum; and a clothes stirring blade protruding higher than the surface of the shock absorbing sheet on the inner periphery of the drum; A plurality of non-slip having a protruding length lower than the stirring blade, wherein the non-slip is formed so as to extend in a depth direction of the drum, and is arranged at intervals in a circumferential direction of the drum; The following effects can be obtained by using a clothes dryer characterized in that the height of the non-slip protruding from the surface of the shock absorbing sheet is set to 10 mm or more and 20 mm or less.

The impact sound of the chuck button on the clothes can be minimized by being absorbed by the shock absorbing sheet.

Even with a sheet having a small friction, slippage of clothing can be suppressed by non-slip, and generation of secondary sounds such as slipping noise can be suppressed.

In particular, since the slip stopper is formed so as to extend long in the front-rear direction of the inner circumference of the drum, no slip noise is generated even with small clothes such as handkerchiefs and shoes. Slip-free operation is particularly suitable for night use.

Since the non-slip is smaller than the clothes stirring blade, it has an inexpensive configuration.

Since the material capacity of the drum is small and the proportion of the material is not occupied by the clothes agitating blades and the non-slip, it can be used effectively, and stable performance can be obtained with less drying unevenness.
