Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a so-called dehumidifying type dryer which is equipped with a heat exchange type hot air supply device mainly including a fan inside the main body. .

(Prior Art) This type of dryer has a box-shaped main body, and a drum for storing clothes to be dried is disposed inside the main body. A heat exchange type hot air supply device is installed to supply hot air. In this case, the heat exchange type warm air supply device uses a centrifugal fan that also serves as a heat exchanger, so it takes in outside air from the center of the fan and exhausts it from the outer periphery of the fan. An outside air inlet is provided at the center of the rear plate of the main body, and an outlet is provided at the outer periphery of the rear plate.

(Problem to be Solved by the Invention) However, in the above conventional configuration, the intake port and the exhaust port for outside air are provided in the center and the outer periphery of the rear plate of the main body, so the intake port and the exhaust port are on the same plane. As a result, there is a risk of a so-called short circuit phenomenon in which warm air discharged from the exhaust port is sucked in again from the suction port, resulting in a reduction in heat exchange performance.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to prevent short circuits and improve heat exchange performance in a heat exchange type air supply device, and to provide a simple structure for such a configuration. To provide a dryer that can be realized by +W construction.

[Structure of the Invention] (Means for Solving the Problems) The dryer of the present invention has a main body having an inlet/outlet for a material to be dried on an upper surface thereof, and a horizontal shaft type in which the material to be dried is accommodated inside the main body. The device is constructed by incorporating a drum, and a heat exchange type air supply device that is adjacent to the drum and mainly includes a fan that supplies hot air into the drum, and the main body is attached to the drum so as to cover the drum. The main body of the outer box enclosing the heat exchange hot air supply device and the side plate of the outer box enclosing the heat exchange hot air supply device are combined together, and the outside air inlet and outlet for the heat exchange hot air supply device are connected to the They are distinctive in that they are provided on different surfaces of the side panels of the outer box.

(Function) The outside air inlet and outlet for the heat exchange type warm air supply device,
Because they are installed on different sides of the outer box side plate of the main body,
Warm air discharged from the exhaust port is no longer sucked into the intake port, and so-called short circuits can be prevented, so that the heat exchange performance of the heat exchange type air supply device can be improved. In addition to the above configuration, the heat exchanger air supply device is enclosed by the outer box side plate, and the heat exchanger air supply device and the outside air intake and outlet are compactly integrated on the outer box side plate. Therefore, there is no need to provide a complicated duct between the heat exchange type air supply device and the suction port and the discharge port, so that the overall structure can be simplified.

(Example) An example of the present invention will be described below with reference to the drawings.

First, in FIGS. 1 to 3, 1 is the main body of the outer box, which consists of a part of the upper cover 2. It consists of a body part 3 having a substantially U-shaped cross section and a bottom plate part 4 made of synthetic resin. Reference numeral 5 denotes an outer box side plate having a substantially inverted U-shape in cross section, and a main body 6 is constructed by joining this outer box side plate 5 to the outer box main body 1. Here, the upper cover part 2 is formed with an entry/exit lower for clothes to be dried, and the upper surface of the main body 6 is provided with the entry/exit lower, making it a top-loading type. Further, the upper cover 2 is provided with a lid 8 for opening and closing the entrance/exit lower part, while the bottom plate part 4 is provided with a motor holding part 9 and a water receiving part 10, as shown in FIG.
is integrally molded.

Reference numeral 11 denotes a horizontal shaft-shaped drum for storing the material to be dried;
The shaft portion 12 provided at the center of the right side in FIG.
The main body 6 is supported via a bearing 13 in a recess 3a formed in a side plate portion of the main body 6, and the opening edge on the left side in FIG. It is rotatably installed inside. This results in
The drum 11 is enclosed by the outer box body 1. As shown in FIG. 4, an opening 11a approximately the same size as the entrance/exit lower is formed in the outer peripheral surface of the drum 11, and a drum lid is provided to open and close this opening 11a. 16 is provided so as to be slidable in the circumferential direction of the drum 11. Numeral 17 is a locking device by which the drum lid 16 is locked in the closed position. Note that a cover 3b is attached to the recess 3a of the body portion 3.

Inside the casing 14, reference numeral 18 denotes a double-blade-shaped fan that is provided to partition the casing 14 into left and right sides, and when this fan is rotated, the warm air inside the drum 11 passes through the filter 19 and the intake port 20. fan 18
is sucked to the right side in Figure 2, and the heater case 2
The drum 11 is heated by a heater 22 disposed in the drum 1 and returned to the drum 11 again. On the other hand, as shown in FIGS. 1 and 3, the outer box side plate 5 is provided with an outside air inlet 23a in the bent piece 23 on the front side thereof, and the bent piece 23 For example, an outside air outlet 24a is provided in the bent piece 24 on the rear surface on the opposite side, which is a different surface.

A cooling duct 25 is disposed between the suction port 23a and the center of the fan 18, as shown in FIGS. 3 and 4. As a result, when the fan 18 is rotated, outside air flows from the inlet 23a of the outer box side plate 5 into the cooling duct 2.
Air from the drum 11 is drawn from the center of the fan 18 through the fan 18 into its left side in FIG. 3 (the left side in FIG. 2), and flows through the right side of the fan 18 in FIG. After exchanging heat with the outer box side plate 5, it is discharged from the outlet 24a of the outer box side plate 5. Here, a heat exchange type air supply device 26 is constituted by the fan 18 as a main body and a heater 22, etc., and the side of this heat exchange type air supply device 26 is an outer box side plate 5.
is covered by. The hot air from the drum 11 is dehumidified by the heat exchange, and the water generated by the dehumidification is drained through a drainage hole 14a provided in the lower part of the casing 14.
(See Figure 4). The water generated by this dehumidification drips into the water receiver 10 of the bottom plate 4 and is discharged from the main body 6 through the drainage hole 10a of the water receiver 10.

In addition, 27 is a mounting band 28 attached to the motor holding part 9 of the bottom plate part 4.
Tightening is done by a fixed motor, and a belt 31 for driving the drum is passed between the pulley 29 and tension pulley 30 attached to the rotating shaft of this motor, and the drum 11. The drum 11 is rotationally driven by a driving device 32 which is configured as a main body. Further, a belt 35 for driving the fan is passed between a pulley 33 attached to the rotating shaft of the motor 27 and a pulley 34 of the fan 18, so that the fan 18 is rotationally driven by the motor 27. It looks like this.

Here, in the conventional top-loading type, during assembly, the drum,
Parts such as motors, fans, heaters, etc. are inserted and assembled, which poses the problem of poor assembly workability. In contrast, in this embodiment, the main body 6 is constructed by combining the outer box main body 1 that encloses the drum 11 with the outer box side plate 5 that encloses the heat exchanger air supply device 26 side. Therefore, during assembly, when the outer case side plate 5 is not connected to the outer case main body 1, that is, when the opening in the body 3 of the outer case main body 1 is open, the drum 11 can be inserted through the opening.
etc. can be assembled into the main body 6, so that the assembly can be done from the side side compared to the conventional case, making the work easier and improving the assembly workability. Especially in the case of this example,
Since the cross-sectional shape of the outer case side plate 5 is approximately inverted U-shaped, the outer case side plate 5 wraps around toward both side surfaces of the body portion 3 of the outer case main body 1, and the opening portion of the body portion 3 increases accordingly. Since the area is widened, the assembly work becomes easier and the assembly work efficiency is further improved.

In the above configuration, the inlet 23a and outlet 24a of the outside air for cooling in the heat exchange type air supply device 26 are connected to the front side bent piece 23 of the outer box side plate 5 of the main body 6.
and the rear side bent piece portion 24, respectively, and an inlet 23a.
Since the exhaust ports 24a are arranged on different surfaces of the side plate 5, the warm air discharged from the exhaust ports 24a is not sucked into the intake port 23a unlike in the conventional case, and so-called short circuits can be prevented.
The heat exchange performance of the heat exchange type air supply device 26 can be improved.

In addition to the above configuration, the heat exchanger air supply device 26 is covered by the outer box side plate 5, and the heat exchanger air supply device 26 and the outside air intake port 23a and the exhaust port 24a are connected to the outer box side plate 5 side. Since the structure is compact, there is no need to provide a complicated duct etc. between the heat exchange type air supply device 26 and the intake port 23a and the discharge port 24a.
The overall configuration can be simplified.

In the above embodiment, the outside air intake port 23a and the exhaust port 2
4a is provided on the front side bent piece part 23 and the rear side bent piece part 24 of the outer box side plate 5, but the present invention is not limited to this. For example, one of the inlet port and the outlet port is provided. One may be provided on the front or rear surface of the outer case side plate 5 and the other may be provided on the side surface of the outer case side plate 5, or one may be provided on the outer case side plate 5 and the other may be provided on a part of the upper cover. It is also possible to provide the suction port and the discharge port on different surfaces of the outer box side plate 5 side.

[Effects of the Invention] As is clear from the above description, the present invention is constructed by combining an outer box main body that encloses a drum and an outer box side plate that encloses a heat exchange hot air supply device side. At the same time, the outside air inlet and outlet for the heat exchange type hot air supply device are provided on different surfaces of the side panels of the outer box, so that the heat exchange performance of the heat exchange type hot air supply device is particularly improved. I can do it,
Moreover, such a configuration can be realized with a simple configuration, which is an excellent effect.
