Description

Vertical compressor and laundry treating apparatus including the same Technical Field The present invention relates to a vertical compressor and a laundry treating apparatus including the same. Background The laundry treatment apparatus is any apparatus for performing management such as washing, drying, or wrinkle removal of laundry or bedding in a home, a laundry, or the like, or for treating laundry. The laundry treating apparatus may include a washing machine, a dryer, a laundry dryer (hereinafter, a washing and drying integrated machine), and the like. The dryer and/or the washing and drying integrated machine evaporates moisture contained in a treatment object such as laundry or bedding put into a drum (or tub) by supplying hot air to the treatment object. In other words, after the moisture of the object to be processed in the drum is evaporated, the air leaving the drum contains the moisture of the object to be processed, and the state of high temperature and high humidity is obtained. At this time, the types of dryers and/or washing and drying integrated machines may be classified into condensing type and exhausting type according to the manner of treating such high-temperature and humid air. For example, the condensing type dryer does not discharge high-temperature humid air to the outside, but circulates and condenses moisture contained in the high-temperature humid air through heat exchange. In contrast, the exhaust type dryer directly discharges high-temperature and humid air to the outside. The condensing type dryer and the exhaust type dryer are structurally different from each other in that the condensing type dryer has a structure for treating condensed water and the exhaust type dryer has a structure for exhausting air. The same applies to the condensing type washing and drying integrated machine. The condensing type dryer and/or the condensing type washing and drying integrated machine (hereinafter, described with a representative example of the condensing type dryer) performs a process of removing moisture by performing heat exchange in air discharged from the drum. Thus, a condensing dryer (hereinafter, simply referred to as dryer) is provided with a compressor for compressing a refrigerant required for a heat exchange process. In the related art, since the compressor is disposed at an upper side of a cabinet of the dryer, in other words, at an upper side higher than the drum, a horizontal compressor is mainly used in consideration of space limitations. However, in the case of the horizontal type compressor, it is not only difficult to stably fix the compressor at the cabinet, but also the compressor and the dryer may vibrate more, so that the reliability of the product is lowered. Thus, in recent years, as described in patent document 1 (korean patent laid-open No. 10-1982533), an example has been proposed in which a vertical compressor is provided on the lower side of a cabinet of a dryer, in other words, on the bottom surface of the cabinet. However, in this case, there is a problem in that the height of the vertical compressor needs to be increased in consideration of the height of the vertical compressor, or in order to reduce the height of the dryer, the height of the vertical compressor needs to be reduced. In the former case, as the height of the dryer of the same capacity increases, not only does the manufacturing cost increase, but also the space required for installation needs to be increased. On the other hand, in the latter case, it is difficult to secure an insulation distance between the housing of the compressor and the driving motor, and oil discharge increases due to a decrease in the discharge space in the housing, and freezing capacity and/or reliability of the compressor also decreases. This is particularly true in the case of application to a twin rotary compressor (hereinafter, referred to as a twin rotary compressor). In the conventional twin rotary compressor, as described in patent document 2 (korean patent laid-open No. 10-2336280), the first compression portion and the second compression portion may be axially aligned, and the first compression portion and the second compression portion form a phase difference of 180 °. The double rotary compressor can offset the vibration generated from the compression parts at both sides, and can greatly reduce the vibration of the whole compressor. In this way, in the dryer in which the compressor mainly performs low-speed operation, the vibration of the compressor can be greatly reduced, thereby eventually reducing the vibration of the dryer. However, in the case of the twin rotary compressor, since the first compression part and the second compression part are arranged in the axial direction as described above, the height of the entire compression part is increased accordingly, and the height of the compressor is also increased, whereby there is a problem in that the height of the dryer is also increased together.
