[0005]
[Problems to be solved by the invention]
In the conventional clothes dryer, it is well known that the clothes in the rotary drum are stirred so that they move downward by a baffle and then drop downward.
[0006]
Therefore, since the rotating drum is inclined upward, the clothes are biased toward the rear of the rotating drum during the stirring operation.
[0007]
In addition, since the air flows from the front to the rear in the rotary drum, the rearward bias of the garment becomes more conspicuous.
[0008]
As a result, the exhaust port on the back side of the rotating drum is likely to be blocked, and the clothes themselves may be insufficiently agitated, resulting in a decrease in drying efficiency.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a rotating drum supported by a rotating shaft inclined with respect to a horizontal direction so that the front having a clothes insertion port is at a high position, and blows air into the rotating drum. In addition, a blowing path provided with heating means in the middle, an exhaust port for discharging the air in the rotating drum to the blowing path, and the air in the blowing path provided on the back surface of the rotating drum are blown into the rotating drum. A blowout hole that is provided on the back surface of the rotating drum, and a recess and a protrusion that are radially extended are provided on the back surface of the rotating drum. Can be suppressed, drying efficiency can be improved, and a good finish can be provided. In addition, the problem that clothing that is biased to the back of the rotating drum by the convex portion blocks the air discharge hole and the drying air is not blown can be avoided. In addition, it is possible to suppress drying spots on clothes and shorten drying time.

[0016]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0017]
Example 1
FIG. 1 shows a clothes dryer, and a rotating drum 2 included in an outer frame 1 is configured to rotate around a rotating shaft 3 inclined so that the front is higher than the rear. The front side of the cylindrical rotating drum 2 is opened so that clothes can be taken in and out through the clothes insertion port 4 provided in the outer frame 1. The clothes insertion port 4 is provided with a lid 5 that can be freely opened and closed.
[0018]
The rotary drum 2 uses a motor 6 as a rotational drive source, and a belt 8 is stretched between the pulley 6 fixed to the rotary shaft 3 and the motor 6 in order to transmit the power of the motor 6 to the rotary drum 2. It is installed.
[0019]
A plurality of baffles 9 extending in the direction of the rotary shaft 3 are attached to the peripheral wall of the rotary drum 2 in the circumferential direction. Further, a cover 10 that covers the back and outer periphery of the rotary drum 2 is provided, and an air passage 11 is formed between them.
[0020]
The rear surface of the rotating drum 2 and the baffle 9 are provided with a large number of air blowing holes 12 and 13, and the air flowing through the ventilation passage 11 is forward from the rear in the axial direction of the rotating drum 2 through the air blowing holes 12 and 13. Further, the air is blown from the outer circumference in the diameter direction of the rotating drum 2 toward the center.
[0021]
The blown air is once exhausted from the exhaust port 14 on the clothing input port 4 side, and is circulated through the path of the heat absorber, the heater 16, and the air blowing holes 12 and 13 by the rotation of the fan 15. The heat absorber cools the air and dehumidifies it, and the heater 16 reheats the air dehumidified by the heat absorber.
[0022]
Note that the heat absorber may be an air-cooled type using outside air, a water-cooled type using cooling water, or a type using a heat pump. In addition to the method in which the drying air circulates in the clothes dryer, the present invention can be applied to a method in which outside air is blown into the clothes dryer and the dried air is discharged outside the clothes dryer. Will not be affected.
[0023]
In the above-described configuration, when the clothes are dried with the rotating drum 2 rotating around the rotating shaft 3, the clothes are lifted to the vicinity of the top of the rotating drum 2 by the baffle 9 provided on the peripheral wall of the rotating drum 2 and knocked down to the bottom. The tumbling is repeated. At this time, since the rotating drum 2 is inclined, the clothing tends to be biased toward the back surface of the rotating drum 2.
[0024]
However, in the above embodiment, since air flows from the rear to the front inside the rotary drum 2, the backward bias of the clothes is suppressed by the momentum of the flow.
[0025]
As a result, the unevenness of clothing can be reduced and the stirring ability can be improved. In addition, the air blowing holes 12 can be prevented from being blocked by clothing, so that the drying efficiency is improved. Furthermore, problems such as dry spots on clothes can be solved by improving the stirring ability and drying efficiency.
[0026]
Further, by providing a large number of air blowing holes 13 in the baffle 9 of the rotating drum 2, air can be blown from multiple directions, not only the drying time is shortened, but also the clothes can be dried without spots.
[0027]
As another embodiment, a configuration for further improving the drying efficiency is shown in FIGS.
[0028]
2 and FIG. 3, the concentric convex portion 18 and the concave portion 19 are provided on the back surface of the rotary drum 2, and the air blowing hole 12 is provided in the concave portion 19. 4 shows a configuration in which convex portions 18 and concave portions 19 are provided radially on the back surface of the rotary drum 2 and the air blowing holes 12 are provided on the concave portion 19 side.
[0029]
According to this configuration, even if clothing is biased on the back surface of the rotary drum 2 due to the inclination of the rotating shaft 3, blockage of the air blowing holes 12 formed in the recesses 19 with the projections 18 being protected is avoided. Therefore, dry spots on the clothes are suppressed and the drying time is shortened.
[0030]
In FIG. 4, the concave portion 19 is formed wider than that in FIG. 2, and a part of the air blowing hole 12 is also provided in the convex portion 18. In addition to the purpose of preventing the air blowout holes 12 from being blocked by clothing, the concave portions 19 are formed wide so that the clothing is easily caught by the convex portions 18. Inhibition of dry spots and shortening of drying time can be realized.
[0031]
Moreover, since the surface area of the back surface of the rotating drum 2 is increased by providing the concavo-convex portion, more air blowing holes 12 are formed, and the drying efficiency is improved.
[0032]
Further, in order to improve the efficiency of drying, providing a guide 20 as shown in FIG. 5 can be considered as another embodiment. That is, the guide 20 has a ring shape and is attached to the ventilation path on the back surface of the rotating drum 2, and is configured to divert the ventilation path on the back surface side and the peripheral wall side of the rotating drum 2.
[0033]
The air heated by the heater 16 is blown from the blower blowing holes 12 and 13 through the ventilation path 11. However, when the guide 20 is not provided, the air blown from the blower blowout hole 13 is compared with the blown amount from the blower blowing hole 12. May be slightly reduced.
[0034]
However, by providing the guide 20, air is sufficiently distributed to the ventilation path 11 on the peripheral wall of the rotary drum 2, so that the difference in the amount of air blown between the air blowing hole 12 and the air blowing hole 13 is reduced, and the clothes are uniformly dried from multiple directions. it can. As a result, dry spots on the clothes are suppressed, and the drying time is shortened.
[0035]
In the first embodiment, the cover 10 is covered with the back surface and the peripheral wall of the rotary drum 2, but the same effect can be obtained even with only the side wall on which the baffle 9 is formed instead of the entire peripheral wall of the rotary drum 2.
[0036]
(Example 2)
Example 2 is a clothes washer / dryer having a washing function and a drying function, and will be described below with reference to FIG.
[0037]
In FIG. 6, 22 is an outer tank, 23 is a water supply port, 24 is a water supply channel, 25 is a water discharge port, 26 is a water discharge channel, 27 is a drainage pump, and the other components are the same as in FIG. In addition, the specific description uses FIG.
[0038]
The outer tub 22 stores water in the lower part of the rotating drum 2 so that it can be washed, and is arranged so as to cover the rotating drum 2. Further, the water supply port 23 is provided in the upper part on the clothing input port 4 side, and the water flows to the water supply port 23 through the water supply passage 24 and is supplied into the rotary drum 2.
[0039]
During washing, the clothes are lifted up to the vicinity of the top of the rotating drum 2 by the baffle 9 provided on the peripheral wall of the rotating drum 2 and repeatedly tumbled to the bottom, thereby removing the dirt on the clothes.
[0040]
After the washing is finished, the drainage flowing from the drainage port 25 provided at the bottom of the outer tub 22 to the drainage channel 26 is drained to the outside through the drainage pump 27.
[0041]
In the drying of the clothes, the same drying as the clothes dryer configured in Example 1 is performed, and thus the details are omitted.
[0042]
Since the clothes washing and drying machine of the second embodiment performs washing and drying as a series of operations, the user does not need a difficult operation and the convenience of carrying the clothes from the washing machine to the dryer becomes unnecessary. Will improve. The clothes washer / dryer of Example 2 can be used alone as a dryer.
[0043]
【The invention's effect】
As described above, according to the present invention, the following effects can be obtained.
[0044]
By blowing air for drying from the back surface of the rotating drum, it is possible to prevent clothes from being biased to the back surface of the rotating drum and improve drying efficiency, thereby providing a good drying finish. In addition, it is possible to avoid the problem that clothes that are biased to the back of the rotary drum by the convex portions provided on the back block the air blowing holes and the drying air is not blown. Improvement of action, suppression of dry spots on clothing, shortening of drying time, etc. can be realized.
