BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil recovery apparatus for a compressor, and more particularly, to an oil recovery apparatus for a compressor that can reduce occurrence of oil mist fumes in an oil tank.

The compressor sucks the external fluid, compresses it, and supplies it to a separate device. At this time, the compressor may have a gear box and / or a bearing to drive the internal rotating body. In particular, a plurality of gears may be disposed in the gear box to transmit the driving force to the rotating body. These gears and / or bearings may be supplied with oil for sealing and smooth operation. At this time, the oil supplied to the gears and / or the bearing is continuously supplied, and in the case of remaining oil used, it can be recovered to the oil tank again.

When the oil is recovered in this manner, oil mist fumes may occur in the oil tank even when the oil is recovered to the oil tank. Such oil mist fumes are stored in the oil tank, which causes a problem of increasing the amount of air pollutants in the oil tank.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide an oil recovery apparatus for a compressor that can reduce the occurrence of oil mist fumes in an oil tank. However, these problems are exemplary and do not limit the scope of the present invention.

According to an aspect of the present invention, there is provided an air conditioner comprising: an inflow passage connected to a compressor to recover oil of the compressor; an oil tank located below the inflow passage and storing oil introduced from the inflow passage through an inlet; An induction slant located in the interior of the tank and having an inclined portion so that one end of the inclined portion can be positioned below the water surface of the oil stored in the oil tank; and an induction slant disposed between the inlet and the induction slant, And an induction guide for allowing the oil introduced through the slurry to flow down on the inclined side surface without falling directly onto the induction slant.

The induction guide may have a conical shape in which the vertex points toward the inlet.

The guide slant may have a flat portion at the lower portion of the inlet, and a portion of the guide in a direction opposite to the vertex may be connected to the flat portion of the guide slant.

Other aspects, features, and advantages other than those described above will be apparent from the following detailed description, claims, and drawings.

FIG. 2 is a perspective view schematically showing the guide of FIG. 1. FIG.

BRIEF DESCRIPTION OF THE DRAWINGS The present invention is capable of various modifications and various embodiments, and specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention and methods of achieving them will be apparent with reference to the embodiments described in detail below with reference to the drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like or corresponding components throughout the drawings, and a duplicate description thereof will be omitted .

In the following embodiments, when various components such as a layer, a film, a plate, etc. are referred to as being "on" another component, this is not only the case where the component is "directly on" . Also, for convenience of explanation, the components may be exaggerated or reduced in size. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for convenience of explanation, and thus the present invention is not necessarily limited to those shown in the drawings.

FIG. 1 is a side elevational view schematically showing a part of a compression-use oil recovery apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view schematically showing an induction guide 128 of FIG.

As shown in FIG. 1, the oil recovery apparatus for a compressor may include an inlet flow path 110 connected to a compressor (not shown) to recover the oil of the compressor. The inlet flow path 110 may be in the form of a pipe. An oil tank 120 is located below the inflow channel 110. The oil tank 120 has an inlet leading to the inlet passage 110, and the oil introduced from the inlet is stored in the oil tank 120. The oil stored in the oil tank 120 may be discharged to the outside of the oil tank 120 through the outflow port formed at the lower portion and the outflow channel 130.

An induction slant 126 is located in the oil tank 120. The induction slant 126 prevents the oil that has entered the oil tank 120 from the inflow channel 110 through the inlet and does not directly fall into the oil phase stored in the oil tank 120.

If the oil that has entered the oil tank 120 through the inlet port drops directly into the oil phase stored in the oil tank 120, the oil level of the oil stored in the oil tank 120 So that the correct amount of oil stored in the oil tank 120 can not be confirmed. Particularly, when the oil that has entered the oil tank 120 through the inlet port directly falls into the oil phase stored in the oil tank 120, the oil mist fume is additionally generated due to the impact upon falling of the oil. The oil mist fumes are stored in a space above the oil stored in the oil tank 120, so that the oil mist can be discharged to the atmosphere according to the pressure change when the surface of the oil stored in the oil tank 120 is swollen to become an air pollution source.

However, in the case of the oil recovery apparatus for a compressor according to the present embodiment, the induction slant 126 is located in the oil tank 120, and the oil that has entered the oil tank 120 from the inlet flow path 110 through the inlet port is oil Falls into the induction slant 126 without falling directly into the oil phase stored in the tank 120. [ In addition, since the guide slant 126 has the inclined portion 124, the oil dropped onto the induction slant 126 moves to the oil stored in the oil tank 120 along the inclined portion 124. The inclined portion 124 of the induction slant 126 is positioned below the water surface of the oil that is temporarily stored in the oil tank 120 so that the oil on the induction slant 126 flows into the oil tank 120, It is possible to prevent the oil mist fume from increasing when entering the oil stored in the oil mist fume storage tank.

Even if the induction slant 126 is used as described above, when the oil that has entered the oil tank 120 through the inlet port 110 from the inlet port 110 drops onto the induction slant 126, oil mist fumes are further generated . In the case of the oil recovery apparatus for a compressor according to the present embodiment, an induction guide 128 is further provided to prevent or minimize the occurrence of such oil mist fumes. The guide slant 126 has a flat portion 122 corresponding to the lower portion of the inlet and the guide 128 can be located on this flat portion 122 of the guide slant 126.

Specifically, the induction guide 128 is disposed between the inlet and the induction slant 126 and has an inclined side so that the oil introduced through the inlet does not directly fall on the induction slant 126, Let them ride down. The oil that has entered the oil tank 120 from the inlet flow path 110 through the inlet flow flows on the inclined side surface of the guide guide 128 from the entrance into the oil tank 120, And then to the oil stored in the oil tank 120 through the slope 124 of the induction slant 126. Therefore, it is possible to prevent or minimize the occurrence of a new oil mist fume after entering the oil tank 120 from the inflow channel 110 through the inlet.

Such an induction guide 128 may have a conical shape in which the vertex points toward the inlet as shown in FIG. Typically, the inlet flow path 110 and its inlet port are circular in cross section. Therefore, the induction guide 128 has a conical shape in which the vertex points toward the inlet, so that the induction guide 128 can be preferentially passed through even if oil is introduced into the oil tank 120 through a certain portion of the inlet. Of course, if necessary, the vertex of the conical guiding guide 128 may be located in the inlet.

On the other hand, the diameter (W 128) of the bottom surface of the case of the circular section of the inlet diameter of the inlet (110 W) than the induction guide of the conical shape 128, this can be to be greater. Ten thousand and one diameter of the inlet (W 110) than the diameter of the bottom surface of the induction guide 128 of conical shape (W 128) is smaller if, the oil through the inner surface of the inlet port enters the oil tank 120 is guided guide in some cases It may fall directly onto the guiding slant 126 without falling onto the slider 128. In this case, oil mist fumes may occur. Therefore, the diameter of the bottom face of the diameter of the inlet (W 110) than the induction guide of conical shape (128) (W 128) is further, by so as to be greater, derived oil is any case entering the oil tank 120 via the inlet slants It is possible to prevent the occurrence of oil mist fumes by minimizing the occurrence of the oil mist fumes by allowing the oil to flow directly onto the induction guide 128 without directly falling onto the oil mist 126.

Of course, the relationship between the inlet and the guide 128 may be determined in a different manner. That is, even when the inlet port has a circular cross-section as well as an arbitrary shape, the area of the bottom surface of the guide guide 128 having the inclined side surface than the inlet cross-sectional area can be made larger. At this time, an orthogonal projection on the bottom surface of the guiding guide 128 on the end face of the inlet can be positioned in the bottom surface of the guiding guide 128. [ The oil that enters the oil tank 120 through the inlet port is prevented from falling directly onto the guide slant 126 in any case and enters the guide 128 first to prevent the occurrence of oil mist fumes Can be minimized.

On the other hand, the portion of the conical guide guide 128 opposite the vertex, that is, the bottom surface of the guide guide 128, may be connected to the flat portion 122 of the guide slant 126. Accordingly, it is possible to prevent oil mist fumes from being generated when the oil on the inclined side surface of the guide guide 128 enters the induction slant 126.

On the other hand, it may be considered that the guide slant 126 does not have a flat portion 122 but has only an inclined portion 124, so that the guide guide 128 is positioned on such an inclined portion 124. However, in such a case, the flow rate of the oil entering the oil tank 120 through the inlet port may not be reduced and may be higher in some cases. The higher the flow velocity of the oil, the less stable the surface of the oil stored in the oil tank 120, thus making it difficult to accurately measure the amount of stored oil or cause an oil mist fume.

However, in the case of the oil recovery apparatus for a compressor according to the present embodiment, the oil introduced through the inlet is moved onto the flat portion 122 of the induction slant 126 through the induction guide 128, So that the oil can enter the pre-stored oil in the oil tank 120 through the inclined portion 124 of the induction slant 126.

Of course, the oil tank 120 may further include various components such as an oil level gauge, a filter, and a heater in addition to the components described above. Of course, some of such components may not be located only in the oil tank 120 but may extend over the inside and outside of the oil tank 120, and may be located outside the oil tank 120, as the case may be.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art . Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
