With the above configuration, an appropriate air diversion such as blowing out the drying air only to the baffle located at a place where the drying can be efficiently performed is realized, and as a result, air having a momentum can be directly blown from the baffle to the clothing. it can.
[0010]
In the present invention, the air outlet is configured to be opened when the baffle is positioned below the rotating drum and closed when the baffle is positioned above the rotating drum. With the above configuration, an appropriate air diversion is realized such that the drying air is fed only to the baffle located at a place where the drying can be efficiently performed. Can be sprayed.
[0011]

[0012]
As a result, it is possible to achieve an appropriate air diversion such that the drying air is blown out when the baffle is positioned below the rotating drum, which is the place where drying can be performed efficiently. It becomes possible to spray on .
[0013]
In order to control the air blowing, an air valve that is slidable in the radial direction of the rotary drum is provided in the baffle, and the air blowing hole is opened and closed by the weight of the air valve. Since gravity is used as the power source of the air valve, it is not necessary to use a power source such as electric power, and it is possible to avoid unnecessary cost.
[0014]
In addition, by providing a sphere in the baffle and opening and closing the air blowing hole according to the weight of the sphere, there is an advantage that it can be realized with an easy configuration of only the sphere, leading to further cost reduction.

[0019]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0020]
(Example 1)
FIG. 1 shows a clothes dryer, and a rotating drum 2 enclosed in an outer frame 1 is configured to rotate around a rotating shaft 3 that is a horizontal direction. 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.
[0021]
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.
[0022]
A plurality of baffles 9 extending in the axial direction and a plurality of baffles 9 extending at equal intervals in the circumferential direction are attached to the inner peripheral wall of the rotating drum 2. Furthermore, the cover 10 which covers the back part and outer periphery of the rotating drum 2 is provided, and the ventilation path is formed between them.
[0023]
The baffle 9 is provided with a large number of air blowing holes 11 and air blowing ports 12 for taking in the drying air from the ventilation passages, and the drying air passes through the air blowing holes 11 from the rear to the front in the axial direction of the rotary drum 2. In addition, the air is blown from the outer circumference in the diameter direction toward the center.
[0024]
The blown drying air is once exhausted from the exhaust port on the clothing input port 4 side, and is circulated through the path of the heat absorber (not shown), the heater 14 and the air blowing hole 11 by the rotation of the fan 13. The heat absorber cools the air and performs dehumidification, and the heater 14 reheats the air dehumidified by the heat absorber.
[0025]
As the heat absorber, an air-cooled one by outside air, a water-cooled one by cooling water, a one using a heat pump, or the like is considered. In addition to the method in which the drying air circulates in the clothes dryer, the method of blowing the outside air into the clothes dryer and discharging it outside the clothes dryer when the drying is finished affects the implementation of the present invention. Does not affect.
[0026]
FIG. 2 shows the configuration of the baffle 9 according to the first embodiment, and a cylindrical air valve 15 having a diameter sufficient to block the air blowing hole 11 in the head is provided in the hollow baffle 9. In order to support the air valve 15 slidably, a support column 16 having a support hole is provided.
[0027]
In FIG. 3 showing the baffle 9 in more detail, (a) shows the time when the baffle 9 is located below the rotating drum 2, and (b) shows the time when the baffle 9 is located above the rotating drum 2. Is.
[0028]
When the baffle 9 is positioned below the rotary drum 2, the air valve 15 supported by the support hole is completely retracted by gravity and the air blowing hole 11 is opened as shown in FIG. Thus, the drying air can be blown to the clothes in the rotary drum 2.
[0029]
On the other hand, when the baffle 9 is positioned above the rotary drum 2, the air valve 15 is moved forward by gravity as shown in FIG. Air cannot be blown.
[0030]
As described above, by providing the air valve 15 in the baffle 9, drying air can be blown to the clothing only when the baffle 9 comes below the rotary drum 2.
[0031]
In the conventional clothes dryer, the drying air warmed by the heater 14 is evenly divided into the respective baffles 9. However, in this embodiment, only the baffles 9 below the rotary drum 2 are distributed. Since the air is diverted, the air that should be sent to the baffle 9 above the rotating drum 2 flows to the baffle 9 below, and the baffle 9 below blows a larger amount of vigorous air. Will be able to.
[0032]
As a result, an improvement in drying efficiency is achieved, such as the ability to directly blow air for drying that has a strong momentum to clothing.
[0033]
In addition, although the air valve 15 was provided with respect to one ventilation blowing hole 11 in FIG. 3, as shown in FIG. 4, the width | variety of an air valve is made long enough and the air quantity of the several ventilation blowing hole 11 is controlled simultaneously. Since the number of air valves can be greatly reduced, there are advantages such as easy mounting, reduced failure rate, and cost reduction.
[0034]
As another embodiment, as shown in FIG. 5, it is conceivable to provide a sphere 17 having a diameter sufficient to block the air blowing hole 11 inside the baffle 9. The sphere 17 can be configured most easily, and has an advantage of leading to cost reduction.
[0035]
When the baffle 9 is positioned below the rotating drum 2, the sphere 17 rolls down inside the baffle 9 due to gravity, so that the air blowing hole 11 is opened, and the clothes below the rotating drum 2 are dried. Air can be blown.
[0036]
On the other hand, when the baffle 9 is positioned above the rotary drum 2, the sphere 17 blocks the air blowing hole 11 due to gravity, and the drying air cannot be blown.
[0037]
In addition, the sphere 17 is used for one air blowing hole 11, but a cylinder may be used instead of the sphere 17, and the air amount of the plurality of air blowing holes 11 may be controlled. Therefore, there are many advantages such as easy mounting, reduced failure rate, and cost reduction.
[0038]
In addition, you may provide the recessed part 18 as shown in FIG. 6 in the shape of the periphery of the ventilation blowing hole 11 so that the said spherical body 17 may be fitted easily.
[0039]
As another embodiment, as shown in FIG. 7, the air blowing hole 11 is closed inside the baffle 9, and an openable / closable air blocking lid 19 and a hinge portion 20 that connects the inner wall of the baffle 9 and the air blocking lid 19 are provided. Is also possible.
[0040]
When the baffle 9 is positioned below the rotating drum 2, the air blowing cover 19 opens the air blowing hole 11 by gravity so that the drying air can be blown to the clothes below the rotating drum 2.
[0041]
On the other hand, when the baffle 9 is positioned above the rotary drum 2, the air blowing cover 18 blocks the air blowing hole 11 due to gravity, and the drying air cannot be blown.
[0042]
According to the configuration in which the ventilation block 19 and the hinge part 20 are provided, there are few restrictions on the installation position, and it can be installed not only around the ventilation blowing hole 11 inside the baffle 9 but also around the ventilation opening 12, for example. it can.
[0043]
Note that the blower blocking lid 19 is used for one blower blowing hole 11, but the length of one side of the blower blocking lid 19 is made sufficiently long so that the air amount of the plurality of blower blowing holes 11 can be controlled. In addition, since the number of blower blocking lids 19 can be greatly reduced, there are advantages such as easy mounting, a reduced failure rate, and cost reduction.
[0044]
As another embodiment, a configuration as shown in FIG. 8 can be considered. That is, the slide valve body 21 that can be opened and closed that closes the air blowing hole 11 inside the baffle 9, and the guide valve 22 on both sides of the slide valve body 21 and the slide valve body 21 are opened and closed because the slide valve body 21 can be opened and closed. A stopper 23 is provided as a stopping device when moving.
[0045]
When the baffle 9 heads downward from the rotating drum 2, as shown in FIG. 9A, the slide valve body 21 moves due to the weight and the air blowing hole 11 is opened. In contrast, the drying air can be blown.
[0046]
On the other hand, when the baffle 9 heads above the rotary drum 2, as shown in FIG. 9B, the slide valve body 21 moves due to gravity and closes the air blowing hole 11, so that the drying air cannot be blown.
[0047]
8 and 9, the shape of the slide valve body 21 is rectangular, but may be any shape as long as it can close the air blowing hole 11.
[0048]
According to the configuration in which the slide valve body 21, the guide 22, and the stopper 23 are provided, there is an effect that the impact force to the baffle 9 generated during the opening / closing operation of the slide valve body 20 can be reduced by the stopper 23.
[0049]
As another embodiment, as shown in FIG. 10, a slide valve body 25 slidable in the diametrical direction of the rotary drum 2 with respect to the air blowing port 12 instead of the air blowing hole 11, and a slide valve body Guides 26 are provided on both sides of the slide valve body so that the slide valve body 25 can slide, and stoppers 27 are provided as stop devices when the slide valve body 25 is opened and closed. It should be noted that the slide valve body 25, the guide 26, and the stopper 27 do not affect the effects of the present invention even if they are installed inside or outside the back surface of the baffle 9.
[0050]
When the air blowing port 12 is positioned below the rotary drum 2, the slide valve body 25 opens the air blowing port 12 by gravity, so that the drying air can be blown to the clothes below the rotating drum 2.
[0051]
On the other hand, when the air blowing port 12 is positioned above the rotary drum 2, the slide valve body 25 blocks the air blowing port 12 due to gravity, and the drying air cannot be blown.
[0052]
In addition, in FIG. 10, although the shape of the slide valve body 25 is a rectangle, if it is a shape which can block the ventilation blowing hole 11, arbitrary shapes may be sufficient as it. Of course, the shape of the air outlet 12 may be any shape as long as the air for drying can flow.
[0053]
According to the configuration in which the slide valve body 25, the guide 26, and the stopper 27 are provided around the air blowing port 12, control is possible with respect to the air blowing ports 12, which is a significantly smaller number than the air blowing holes 11, which is necessary for the configuration. The material can be suppressed as much as possible.
[0054]
As described above, according to the above configuration, the air that should be sent to the baffle 9 above the rotating drum 2 flows to the baffle 9 below, and the baffle 9 below is compared with that of a conventional clothes dryer. Thus, a large amount of vigorous air can be blown, thereby improving the drying efficiency of the clothes.
[0055]
(Example 2)
11A is a cross-sectional view of the rotary drum 2 and the cover 10 portion, and FIG. 11B is a perspective view of the cover of the clothes dryer. The cover 10 is close to the blower opening 12 opened on the back of the rotary drum 2. In this way, the wind tunnel portion 31 is formed so as to be integrated with a part of the cover 10, and by providing the wind tunnel portion 31 at a point where the blower port 12 passes when rotating, the blower port is temporarily provided. 12, air is sent into the baffle 9. Moreover, the front-end | tip of the wind tunnel part 31 was made into the open state so that it could communicate with the ventilation port 12 more easily.
[0056]
By installing the cover 10 having the wind tunnel portion 31 below the rotating drum 2, air can be blown to the clothing only when the baffle 9 comes below the rotating drum 2.
[0057]
As shown in FIG. 12, the cover 10 is not provided with the wind tunnel portion 31, but the upper half of the rear surface of the rotary drum 2 is closed and the lower half is opened, and the air blowing port 12 is located below the rotary drum 2. The same effect can be obtained even if air enters through the air outlet 12 only when it comes.
[0058]
As described above, according to the above configuration, the air that should be sent to the baffle 9 above the rotating drum 2 flows to the baffle 9 below, and the baffle 9 below is compared with that of a conventional clothes dryer. Thus, it is possible to blow a large amount of vigorous air, thereby achieving an improvement in drying efficiency, such as being able to directly blow vigorous drying air against clothes.
[0059]
In addition, although what was mentioned in the said Example 1 and Example 2 was the structure using gravity, the structure which used electric power etc. as motive power may be sufficient.
[0060]
For example, a device having a positionable sensor attached to each baffle 9 and having an openable / closable lid attached in the vicinity of the air blowing hole 11 and the air blowing port 12 only when the position sensor recognizes that the position sensor is located below the rotary drum 2. It may be configured to send a signal and open the lid.
