The present invention relates to a blowing system for a laundry dryer, and in particular, to allow the cross flow fan to reciprocate along the inside of the housing of the laundry dryer, thereby allowing the air to be evenly blown to the entire area of the drying rods to which the laundry is dried. In addition, it is possible to increase the drying efficiency of the laundry, and also relates to a laundry dryer blowing system that can be effectively applied to various types of laundry dryers, such as a cabinet-type laundry dryer or a mobile laundry dryer.

As an example of a laundry drying system, various types of laundry dryers are installed and used in the interiors and verandas of various residential areas such as apartments and general houses. For example, many electric laundry dryers have recently been installed and used. Mobile clothes dryers are also widely used. For example, the electric laundry dryer is configured to be installed on the ceiling of a room or a veranda in order to increase the utilization of the indoor space.

Ceiling mounted electric laundry dryers are well represented in the prior art, such as Korean Utility Model Publication No. 2005-95295. Such an electric laundry dryer includes a housing 10 having a lower portion opened and closed by a cover 12 and fixed to a ceiling, as shown in FIGS. 1 and 2; A pair of holders 22a, 22b disposed on both lower sides of the housing 10, and a plurality of drying rods 24 supported in parallel at predetermined intervals across the holders to hang the laundry. A drying rack 20; A pair of expansion links 30a and 30b having an upper end coupled to the housing 10 and a lower end coupled to the holders 22a and 22b; And, the transmission device for stretching and contracting the expansion link (30a, 30b); is made to include.

The transmission device 40 is alternately wound around the motor 42 installed in the housing 10, the bobbins 44 coupled to the shaft of the motor, and the bobbin 44. Both ends may include wires 46a and 46b connected to lower ends of the holders 22a and 22b or the elastic links 30a and 30b, respectively.

In addition, at least one blower 50 may be further installed at the bottom of the housing 10 to blow wind toward the drying rod 24, and at least one heater 60 to blow hot air. ) Can be installed further. In this case, an axial blower is mainly applied to the blower 50, and as shown in FIG. 3, the wind from the blower 50 is a portion of the cover 12 corresponding to the blower 50. Blowing grill (Grille) 14 for blowing the air toward the drying rod 24 is installed. In FIG. 2, reference numeral 48 denotes a support roller for guiding the winding and sea-circle while supporting the wires 46a and 46b. In FIG. 3, reference numeral 16 denotes the elastic links 30a and 30b and the wire 46a. , 46b) shows a movement path formed at both ends of the cover 12 so as to be movable.

According to the conventional electric laundry dryer configured as described above, for example, when the motors 42 are driven down by unshown operation switches or remote controllers, and the wires 46a and 46b are released, the wires 46a and 46b are loosened. As a result, the length of the stretchable links 30a and 30b extends downward, thereby lowering the drying rack 20. When the position of the drying rod 24 of the drying table 20 is lowered to an appropriate position, the driving of the motor 42 is stopped, the laundry is placed on the drying rod 24, and then the motor 42 is moved to an appropriate position. Raise.

However, in the electric laundry dryer having the above structure, there are the following problems.

That is, since the axial flow blower is applied to the blower 50, and the blow grill 14 having an area corresponding to the blower 50 is formed in the cover 12 so as to blow the wind, the blow grill 14 Wind or warm air blown through the) is blown locally to the laundry hanging on the drying rod (24). Because of this, the laundry over the entire area of the drying rods 24 is not evenly dried as a whole and a difference occurs in the drying time, and as a result, the original purpose of drying the laundry quickly cannot be achieved.

However, even in this technique, since the blowing grill for substantially blowing wind toward the laundry hanging on the drying rods of the cover is formed relatively narrowly only in the longitudinal direction in a part of the cover, that is, in the center, It is effective, but the fact that the wind is locally blown is no different from the former, it is not possible to effectively increase the drying efficiency. In addition, since the cross flow fan is arranged such that the axis of the cross flow fan and the axis of the fan motor are arranged on the same line, the length of the cross flow fan cannot be lengthened as much as the protruding length of the fan motor. There is also a problem that cannot be done.

The present invention is made in consideration of the above-described conventional problems, by allowing the cross flow blower to reciprocate along the inside of the housing of the laundry dryer, it is possible to blow the wind evenly to the entire area of the drying rods to hang the clothes, and also the ceiling-mounted clothes dryer In addition, it aims to be effectively applied to various types of clothes dryers, such as a cabinet type laundry dryer or a mobile clothes dryer.
