Abstract

PURPOSE:To suppress the air cutting noise generated at a body side exhaust port by positioning a body member edge part forming a body side exhaust port inside the body and projecting a casing exhaust port edge part from the body side exhaust port and setting said edge part into the nonprojecting state from the body outer surface. CONSTITUTION:The exhaust port edge part 24a of a body member is turned back inward from the outer surface 1a of the body, and a casing exhaust port edge part 23a is projected from the turned-back exhaust port edge part 24a, and is set into the non-projecting state from the body outer surface 1a. With such constitution, the cooling air supplied from a casing exhaust port 23 does not collide the body member edge part 24a, and the air cutting noise generated at the edge part 24a can be suppressed. Further. when a body 1 is placed on a floor, etc., in the assembly or installation work, the edge part 23a of the casing exhaust port 23 does not collide the floor surface, and the cooling air casing is prevented from being applied with an unnecessary force.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a dehumidifying type clothes dryer using a heat exchange fan for use in general households.

Conventional technology A conventional example is shown in FIG.

In FIG. 2, 1 is the main body of the dryer, 2 is a rotary drum rotatably provided in the main body 1 and driven by a motor 3 via a drum belt 4, and 5 is a clothing input provided on the front of the main body 1. 6 is a heater that heats the drying air flowing into the rotating drum 2, and 6 is a heat exchange fan installed at the rear of the rotating drum 2, which has air blowing and heat exchange functions.
c, 9 driven by the motor 3 via the fan belt 8
is a drying air side casing of the heat exchange fan γ, which is provided on the rear surface of the rotating drum 2, and has a rotating drum side intake hole 1o in the center. 11 is a filter installed on the rear surface of the rotary drum 2 to remove lint, etc.; 12 is a cooling air casing, which, like the drying air casing 9, has a cooling side intake port 13 in the center. Reference numeral 14 denotes a cooling air casing exhaust port formed in a part of the cooling air casing 12, and is located in the same position as the main body side exhaust port 15, which is also provided in a part of the main body 1. A shaft 16 rotatably supports the heat exchange fan 7 and the rotating drum 2, and is fixed to a retaining plate 17 that fixes the drying air casing 9 and the cooling air casing 12 to the main body 1. A partition plate 18 is interposed between the drying air casing 9 and the cooling air casing 12, and partitions the outer circumference of the heat exchanger 7 to the left and right to airtightly separate the drying side and the cooling side. 19
is a circulation duct, which functions as a ventilation path for guiding the exhaust air from the drying air casing 9 to the heater 6. Further, a 2° angle was provided in the middle of this circulation duct 19. Condensed water generated by heat exchange in the heat exchange fan 7 is discharged from the drain port. Reference numeral 21 denotes a back plate that covers the rear surface of the main body 1, and a part thereof has an intake port 22 for sucking cooling air.

Note that arrow B indicates the flow of cooling air, and arrow B indicates the flow of drying air.

When the motor 3 in the clothes dryer rotates, the rotary drum 2 containing clothes and the heat exchange fan rotate, creating an air flow B. and drying space [8 is heater 6]
As a result, the clothes in the rotating drum 2 are heated and dried, resulting in high temperature and humidity, which is then circulated to the heat exchanger 1 and 7. On the other hand, the cooling air system takes in outside air from an intake port 22 provided on the back plate 21, and exhausts it to the outside through the casing exhaust port 14 of the cooling air casing 12 and the main body side exhaust port 16 provided on the main body 1. be done. The circulated hot and humid drying air comes into contact with the heat exchange fan 7, is cooled and dehumidified by the cooling air, and is circulated into the rotating drum 2 again. As described above, clothes are dried.

Problems to be Solved by the Invention Here, in the conventional configuration, the noise value is high, especially when the air discharged from the casing exhaust port 14 of the cooling air casing 12 passes through the main body side exhaust port 15 provided in the main body 1. Due to the influence of the tip of the sheet metal material of the main body 1 that forms this exhaust port 16, wind noise is generated at the tip, and this wind noise is a major factor in increasing the noise level. I understand. Also, due to mass production, the positions of the casing exhaust port 14 and the main body side exhaust port 15 may be slightly shifted as shown in Figure 3. In this case, the 151L section will cut off the airflow, further reducing the noise level. This resulted in an increase in

The present invention provides a low-noise clothes dryer in which the wind noise generated at the exhaust port on the main body side is reduced.

Means for Solving the Problem The end of the main body member forming the main body side exhaust port is located inside the main body, and the casing exhaust port end is made to protrude from the main body side exhaust port and not protrude from the outer surface of the main body. The cooling air coming out of the casing exhaust port is prevented from hitting the end of the main body member forming the main body side exhaust port.

Effect: With the above configuration, the cooling air coming out of the casing exhaust port will not hit the end of the main body member forming the main body side exhaust port, that is, no wind noise will be generated here. This can significantly reduce noise levels.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings. FIG. 1 shows the main parts of the present invention.

In Figure 1, 23 is the casing exhaust port, 231L
24 is the end of the exhaust port 23, 24 is the main body side exhaust port provided in the main body 1, and 24a is the end of the main body member made of a sheet metal material forming the exhaust port 24. As shown in this figure, the exhaust port end 24& of the main body member is connected to the outer surface 1 &
Fold more inward and connect the casing exhaust port end 231
L is made to protrude from this folded exhaust port end 241L,
Moreover, it is in a non-protruding state from the outer surface 11L of the main body.

With the above configuration, the casing exhaust port 2
The cooling air coming out from the casing exhaust port 2 does not hit the main body member end 24&, and the wind noise generated at this end 24& is eliminated.
The end portion 23& of 3 does not protrude from the outer surface 1a of the main body.

Therefore, even if the main body 1 is placed on the floor etc. during assembly or installation work, the end 23 & of the casing exhaust port 23 will not touch the floor, and therefore the reaction force of the dryer's own weight will be applied from the floor. Therefore, unnecessary force is not applied to the cooling air casing 12.

Furthermore, in this embodiment, by inserting the exhaust port 23 of the assembled main cooling air casing 12 into the main body side exhaust port 24, the effects of the present invention can be definitely expected. That is, the conventional problem of increased wind noise due to misalignment as shown in FIG. 3 due to component precision and assembly precision is completely solved.

Effects of the Invention As described above, the end of the main body member forming the main body side exhaust port is located inside the main body, and the casing exhaust port end protrudes from the main body side exhaust port, but does not protrude from the outer surface of the main body. By doing so, the noise level of the dryer is reduced, and unnecessary force is not applied to the cooling air casing during assembly or installation, and the reliability of assembly is improved and variations in noise level are reduced. It can be said to be an extremely effective means in practice as it has the effect of suppressing this.
