Abstract

The vertical compressor according to the present invention and the clothing processing device applying the same comprise a drive motor, a compression unit, and a casing. The casing is formed with an opening end of an intermediate shell formed in a tubular shape, and a cap insertion part is formed so that the opening end of the cap is inserted by expanding in the radial direction of the rotation axis, and the opening end of the cap may overlap with the drive motor in the radial direction of the rotation axis. Through this, the height of the vertical compressor can be lowered to minimize the space required for installation of the vertical compressor while simultaneously reducing vibration of the vertical compressor. Furthermore, while lowering the height of the vertical compressor, the oil separation space of the vertical compressor can be expanded to reduce oil discharge from the compressor. Additionally, while lowering the height of the vertical compressor, an insulation distance between the casing and the drive motor can be secured, and while lowering the height of the vertical compressor, the assemblability of the casing can be secured.

Description

Vertical Type Compressor and Laundry Treating Apparature Equipped with This The present invention relates to a vertical compressor and a clothing processing device equipped with the same. A clothing processing device refers to any device used to manage or process clothing, such as washing, drying, or removing wrinkles from clothing or bedding, in a home or at a place like a dry cleaner. A clothing processing device may include a washing machine, a dryer, a washing machine and dryer (hereinafter referred to as a washer-dryer), etc. Dryers and/or washer-dryers supply hot air to items to be processed, such as clothing or bedding, fed into a drum (or tub) to evaporate the moisture contained within them. In other words, as the moisture from the items is evaporated within the drum, the air exiting the drum absorbs the moisture, becoming hot and humid. Depending on how this hot and humid air is processed, dryers and/or washer-dryers can be classified into condensation and exhaust types. For example, condensing dryers condense the moisture contained in hot and humid air through heat exchange while circulating the air, rather than expelling it to the outside. In contrast, exhaust dryers directly expel hot and humid air to the outside. They differ structurally in that condensing dryers have a structure for handling condensate, while exhaust dryers have a structure for exhausting air. This is also true for condensing washer-dryers. A condensing dryer and/or a condensing washer-dryer (hereinafter, a condensing dryer is used as a representative example) performs a process of removing moisture from air discharged from a drum through heat exchange. Accordingly, a condensing dryer (hereinafter abbreviated as "dryer") is equipped with a compressor that compresses the refrigerant required for the heat exchange process. Conventionally, horizontal compressors have been mainly applied due to space constraints, as the compressor is installed on the upper side of the dryer cabinet, that is, above the drum. However, in the case of horizontal compressors, it is not easy to securely fix the compressor to the cabinet, and the reliability of the product may be reduced as the compressor and dryer vibrate more significantly. Accordingly, recently, examples have been introduced in which a vertical compressor is installed on the lower side of the dryer cabinet, that is, on the floor surface of the cabinet, as described in Patent Document 1 (Korean Registered Patent No. 10-1982533). However, in this case, there is a problem in that the height of the dryer must be increased to accommodate the height of the vertical compressor, or the height of the vertical compressor must be lowered to reduce the height of the dryer. In the former case, the height of the dryer increases relative to the same capacity, which not only increases manufacturing costs but also leads to an increase in the required installation space. On the other hand, in the latter case, it is difficult to secure the insulation distance between the compressor casing and the drive motor, and the discharge space within the casing is reduced, which increases the discharge volume and may lower the cooling power and/or reliability of the compressor. This can occur even more significantly, especially when a twin rotary compressor (hereinafter referred to as a compound rotary compressor) is applied. Conventional compound rotary compressors, as described in Patent Document 2 (Korean Registered Patent No. 10-2336280), have a first compression section and a second compression section arranged along the axial direction, and the first and second compression sections may be formed with a phase difference of 180°. In such compound rotary compressors, vibrations generated in both compression sections are canceled out, thereby significantly reducing the overall compressor vibration. Accordingly, the compressor vibration in a dryer, where the compressor mainly performs low-speed operation, can be greatly reduced, ultimately reducing the vibration of the dryer. However, in the case of compound rotary compressors, as explained above, since the first and second compression sections are arranged along the axial direction, the height of the entire compression section increases accordingly, which leads to an increase in the height of the compressor and, consequently, an increase in the height of the dryer. In addition, in conventional double-type rotary compressors, an upper cap is inserted into the top of an intermediate shell having the same inner diameter at both the upper and lower ends, and is coupled such that the upper cap is spaced axially away from the top of the drive motor. Accordingly, when assembling the upper cap to the intermediate shell, interference between the upper cap and the drive motor is prevented, while simultaneously ensuring an insulation distance between the casing and the drive motor. However, in conventional double-type rotary compressors, the height of the compressor increa
