Structure for preventing gap between blewer housing and connection duct in clothes dryer}
[12] The present invention relates to a laundry dryer, and more particularly, to an assembly structure of a front cabinet and a front support.
[13] In general, a laundry dryer is a device for automatically drying a dry object (for example, clothing) in a wet state in which washing is completed, and the conventional configuration of the laundry dryer is as follows.
[14] 1 is a perspective view schematically showing the appearance of the clothes dryer, the clothes dryer main body (B) is a base (1) forming a floor, a front cabinet (2) forming a front, a side cabinet (3) forming a side, It includes a back cover (4) forming a back side, a top cover (5) installed on the cabinet top, and a control panel (6) installed behind the top cover (5).
[15] In general, the laundry dryer has an inlet formed in the front cabinet 2, which is an element constituting the main body B, so that the laundry can be put in and taken out of the laundry, and a drying drum (not shown) is provided in the main body B. It is rotatably installed by receiving the driving force of this motor.
[16] In addition, the front cabinet 2 is provided with a door 10 for selectively opening and closing the inlet.
[17] In addition, a hot air supply passage and a hot air discharge passage are connected to the drying drum, and a heater (not shown) is installed on the hot air supply passage to heat the air introduced from the outside to a high temperature state. A blower 7 for generating a blowing force is provided to force the air heated by the heater to flow in and to discharge the air after the completion of drying to the outside of the main body B.
[18] On the other hand, on the hot air discharge flow path between the drying drum and the blower (7) is provided with a filter cover (8) in which a linter filter (11) is mounted therein, and a connection duct (9) connected to the filter cover (8) is provided. .
[19] Referring to the drying operation according to the conventional laundry dryer made in such a configuration as follows.
[20] First, after the drying object is put into the drying drum, the drying stroke is performed, and a heater and a motor (not shown) are operated.
[21] As the exhaust fan is operated, hot air generated by the high temperature of the external air introduced into the main body B through the suction side of the hot air supply flow passage is forced to flow into the drying drum through the hot air supply flow passage.
[22] Subsequently, the hot air introduced into the drying drum repeats the circulation discharged to the outside of the main body B through the discharge side of the hot air discharge passage while evaporating the moisture of the dry object in the wet state by the suction blowing force of the exhaust fan. When the drying drum is rotated at a low speed by receiving the driving force of the motor by the belt, the drying object is dried in this process.
[23] However, such a laundry dryer has air in the drying drum flowing through the air suction hole 800 formed in the filter cover 8, passing through the linter filter 11, and then connected to the blower 7 along the connection duct 9. In the related art, as shown in part A of FIG. 2, a gap occurs between the blower housing 7a of the blower 7 and the connection duct 9 due to vibration or the like during operation of the dryer. .
[24] When a gap is generated between the blower housing 7a and the connection duct 9 of the blower 7, as shown by the arrow in FIG. 2, the gap between the blower housing 7a and the connection duct 9 is shown. Through the air blower (7) side through the air intake of the drying drum rather than the intake is made, thereby reducing the blowing efficiency of the blower (7) is eventually a problem that the drying efficiency and drying performance of the clothes dryer itself is also reduced Will occur.
[25] The present invention has been made to solve the above-mentioned conventional problems, by improving the structure of the laundry dryer, so that the gap between the blower housing and the connection duct can be effectively prevented to prevent unnecessary air intake to the blower side. The purpose of the present invention is to prevent the deterioration of drying efficiency due to diminished performance.

[26] In order to achieve the above object, the present invention provides a base forming the bottom of the body, a front cabinet forming the front of the main body, a side cabinet forming the side of the main body, a back cover forming the back of the main body, the front cabinet and the side cabinet and the bag The laundry includes a top cover installed at the top of the cover, a filter cover installed at the rear of the front cabinet, a connection duct connected to the inlet side of the filter cover, and a blower installed to be connected to the outlet side of the connection duct. In a dryer; Between the front cabinet and the connection duct, it is characterized in that the pressing member for applying a pushing force to the blower side with respect to the connection duct so that the connection between the blower housing of the connection duct and the blower is installed.
[27] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
[28] Figure 3 is a longitudinal sectional view showing the main part of the present invention, the present invention is a base (1) forming the bottom of the main body (B), the front cabinet (2) forming the front of the main body (B) and the main body (B) side A side cover (3), a back cover (4) forming the back of the main body (B), and a top cover (5) installed on the front cabinet (2), the side cabinet (3) and the back cover (4); And a filter cover 8 installed at the rear of the front cabinet 2, a connection duct 9 connected to an inlet side of the filter cover 8, and an outlet side of the connection duct 9. In a laundry dryer including a blower (7) to be; Pushed toward the blower 7 with respect to the connection duct 9 such that the connection duct 9 and the blower housing 7a of the blower 7 are closely contacted between the front cabinet 2 and the connection duct 9. The pressing member 13 for applying a force is installed.
[29] At this time, the pressing member 13 is made of an elastic body that is elastically compressed between the front cabinet 2 and the connection duct 9 and always gives a pushing force due to the elastic restoring force to the connection duct 9. This is preferable, and rubber is mentioned as an example of the material of the said elastic body.
[30] However, the pressing member 13 does not necessarily need elasticity. That is, an inelastic material having a thickness slightly larger than the gap between the front cabinet 2 and the connection duct 9 when the connection duct 9 is in close contact with the blower housing 7a is also connected to the front cabinet 2. When installed between the ducts 9, it can act as the pressing member 13.
[31] On the other hand, the pressing member 13 may be attached to only one of the front cabinet 2 or the connection duct 9, especially when the pressing member 13 is an inelastic material.
[32] The operation of the present invention configured as described above is as follows.
[33] In the clothes dryer, air in the drying drum flows through the air suction hole 800 formed in the filter cover 8, passes through the linter filter 11, and then flows into the blower 7 along the connection duct 9. If a gap occurs between the blower housing 7a of the blower 7 and the connection duct 9 due to the vibration or the like during operation of the dryer, the blower may be opened through a gap between the blower housing 7a and the connection duct 9. 7) Unnecessary air intake from other than the air inside the drying drum is made to the side.
[34] However, the laundry dryer according to the present invention is connected between the front cabinet 2 and the connection duct 9, as the pressure member 13, which acts to push the connection duct 9 toward the blower 7, is installed. The occurrence of a gap between the duct 9 and the blower housing 7a of the blower 7 is prevented.
[35] That is, the laundry dryer of the present invention is an urging member made of an elastic member that is compressed between the front cabinet 2 and the connection duct 9 and is elastically applied to the connection duct 9 due to the elastic restoring force. (13) or an inelastic urging member 13 having a thickness slightly larger than the gap between the front cabinet 2 and the connection duct 9 when the connection duct 9 is in close contact with the blower housing 7a. By being installed, the connection duct 9 is always in close contact with the blower housing 7a of the blower 7 in spite of the vibration or the like caused by the operation of the dryer, thereby preventing the occurrence of gaps.
[36] Therefore, as described above, a gap is generated between the connection duct 9 and the blower housing 7a of the blower 7 by the pressure member 13 installed between the front cabinet 2 and the connection duct 9. As it is prevented, the blower 7 blocks unnecessary air intake from other spaces than from inside the drying drum, thereby improving the drying efficiency and performance of the clothes dryer.
[37] On the other hand, the embodiment of the present invention as described above is configured to help the understanding of the present invention is not limited only to the above-described embodiment, various modifications are possible within the scope without departing from the spirit of the present invention.
