Hereinafter, with reference to the accompanying drawings a preferred embodiment according to the present invention will be described in detail.

As shown in FIG. 2, the air conditioner according to the present invention includes an indoor unit 10 installed in an indoor space of a building and an outdoor unit 20 installed outside of a building, which can be separated from each other. The indoor unit 10 includes an indoor heat exchanger (not shown) for heat exchange of indoor air and a circulation fan (not shown) for circulation of indoor air, and the outdoor unit 20 includes a compressor 21 for compressing a refrigerant. The outdoor air exchanger 22 and the outdoor air blower fan 23 for heat exchange of the outdoor heat exchanger 22 are embedded. The indoor unit 10 and the outdoor unit 20 are connected to each other through the refrigerant pipe 24 through which the refrigerant flows.

In addition, a separate oxygen device chamber 30 is provided on the upper part of the outdoor unit 20 and is partitioned from the lower heat exchange chamber 25 in which the compressor 21 and the outdoor heat exchanger 22 are installed. In the oxygen device chamber 30, an oxygen generator 40 for extracting oxygen contained in air and an oxygen supply pump 70 for supplying oxygen generated by the oxygen generator 40 toward the indoor unit are installed.

As shown in FIG. 2, the oxygen equipment room 30 is distinguished from the heat exchange chamber 25 at the bottom through the bottom plate 31 installed to partition the internal space of the outdoor unit case 26 into the upper and lower parts. A detachable upper cover 32 is coupled to the upper portion of the upper portion 30, that is, the upper opening portion of the outdoor unit case 26, and is configured to be openable. This configuration is such that the heat generated from the heat exchanger 22 or the compressor 21 in the lower portion is not transferred to the oxygen generator 40 in the upper portion, and the oxygen generator 40 and the oxygen are opened through the opening of the upper cover 32. It is to facilitate the troubleshooting of the supply pump (70). In addition, the oxygen equipment room 30 is located at the top to protect the oxygen generator 40 and the oxygen supply pump 70 from the risk of flooding.

As shown in FIGS. 3 and 4, the oxygen generator 40 in the oxygen equipment room 30 has a flow path formed therein for allowing air to pass therein, and an inlet 42 and an outlet 43 are formed at both ends, respectively. An oxygen generator case 41 is provided. In addition, an oxygen extractor 50 is installed inside the case 41 to separate and extract oxygen from air passing through the internal flow path, and the inlet 42 of the case 41 flows into the oxygen generator 40. A detachable filter 60 is installed to filter foreign substances in the air. At the outlet of the case 41, a blower fan 44 is installed to allow air to flow through the flow path inside the case 41.

The oxygen generator case 41 is provided by bending molding of an iron plate having a predetermined width and length, and an outer frame including a blower fan coupling portion 41a and two side portions 41b having an outlet 43 formed therein, The upper plate 41c and the lower plate 41d are coupled to each other in a state spaced apart from the inside of the outer frame so that a flow path is formed therein. At this time, the lower plate 41d is installed on the upper spaced apart from the lower end of the two side portions 41b to be spaced apart from the bottom plate 31 forming the bottom of the oxygen equipment room 30, the upper plate 41c and the top of the side portion 41b It is fixed in the spaced lower position. The lower plate 41d is spaced apart from the bottom of the oxygen device chamber 30 in order to prevent a phenomenon in which heat transferred from the heat exchange chamber 25 under the outdoor unit 20 is transferred toward the oxygen extractor 50.

In addition, the case 41 of the oxygen generator 40 has a flow path expansion portion 45 of a predetermined section such that the inner flow passage gradually increases toward the outlet on the outlet 43 side close to the blower fan 44. The flow path expansion part 45 is such that air introduced into the inlet 42 of the case 41 can flow smoothly toward the blowing fan 44. The upper plate 41c and the lower plate 41d have bent portions 41e and 41f that are bent in the upward and downward directions at portions adjacent to the outlet 43 for the configuration of the flow path expansion portion 45, respectively.

As shown in FIG. 5, the oxygen extractor 50 inside the case 41 includes a plurality of oxygen extracting plates 52 stacked in a spaced apart state through the spacer 51. This is to allow air to flow into the spaced space between each oxygen extraction plate 52 when the blower fan 44 is operating, the oxygen extraction plate 52 to be described later by the configuration of the oxygen extraction plate 52 Extraction is done.

Each oxygen extraction plate 52 has an oxygen flow passage 53 formed in a lattice groove shape over the entire surface of one side surface, and the inlet portion 71 and the oxygen suction pipe of the oxygen supply pump 70 are formed at the corners thereof. An oxygen discharge hole 54 is formed to be connected via 73, and the oxygen flow passage 53 and the oxygen discharge hole 54 are configured to communicate with each other through the linkage passage 55. In addition, an oxygen filtration film 56 covering the oxygen flow path 53 is attached to the surface of the oxygen extraction plate 52 on which the oxygen flow path 53 is formed.

This configuration is such that oxygen in the air flowing into the spaced space between each oxygen extraction plate 52 is extracted through the oxygen filtration membrane 56, the extracted oxygen is oxygen through the oxygen passage 53 and the oxygen discharge hole 54 It is to flow toward the supply pump (70). This allows extraction of oxygen in the air by using the characteristic that the diffusion rate of oxygen molecules passing through the oxygen filtration membrane 56 is 2.5 times faster than nitrogen molecules in the air when the air passes through the oxygen filtration membrane 56. . That is, oxygen is extracted by using the characteristic that oxygen molecules pass through the oxygen filtration membrane 56 faster than nitrogen molecules and are filtered.

Since the oxygen extractor 50 thins oxygen in the air when the air temperature is high, the amount of oxygen extracted through the oxygen filtration membrane 56 is also significantly reduced. Therefore, when the oxygen generator 40 is installed, it is preferable to increase the extraction effect of oxygen by separating the air flowing into the oxygen extractor 50 from the surrounding heat source.

In the present invention in consideration of such a phenomenon, the oxygen supply pump is divided into an oxygen generating chamber 34 in which the oxygen generator 40 is installed and a pump chamber 35 in which the oxygen supply pump 70 is installed. The heat generated from 70 is prevented from being transferred to the oxygen generator 40.

That is, as shown in FIG. 3, the oxygen generator 40 installed in the oxygen generating chamber 34 of the oxygen machine chamber 30 has an oxygen supply pump 70 at the outlet 43 on which the blowing fan 44 is mounted. It is installed to face. In addition, a plurality of closing members 36 having a predetermined elasticity are inserted into and fixed in the spaced space between the outer surface of the outlet 43 side of the oxygen generator 40 and the outdoor unit case 26, whereby the inside of the oxygen equipment chamber 30 is oxygenated. It is divided into the generating chamber 34 and the pump chamber 35.

In addition, a plurality of outside air flow holes 37 are formed at the side of the oxygen generating chamber 36 (the side of the outdoor unit case) so that outside air having a relatively low temperature can flow into the inlet 42 of the oxygen generator 40. In addition, a plurality of external air distribution holes 38 are also formed on the side of the pump chamber 35 to allow the oxygen supply pump 70 to cool through the inflow of external air.

In addition, as shown in FIGS. 6 and 7, the bottom plate 31 of the pump chamber 35 in which the oxygen supply pump 70 is installed is provided with oxygen by suction force of the outside air circulation fan 23 installed in the lower heat exchange chamber 25. A ventilation hole 80 is formed in which the heat exchange chamber 25 and the pump chamber 35 communicate with each other so that the supply pump 70 may be cooled. This causes the suction force of the outside air circulation fan 23 installed in the heat exchange chamber 25 to act on the pump chamber 35 so that the air introduced into the pump chamber 35 through the outside air flow hole 38 on the side of the pump chamber 35 is oxygen. After cooling the supply pump 70 is introduced into the lower heat exchange chamber 25 through the ventilation hole 80, it is to be discharged to the outside by the outside air circulation fan (23). This allows the pump chamber 35 in the oxygen equipment chamber 30, in which the oxygen supply pump 70 is installed, to be partitioned from the heat exchange chamber 25, but to cool the oxygen supply pump 70 without a separate cooling fan. .

In addition, the upper part of the vent hole 80 of the pump chamber 35 to fix the oxygen supply pump 70, the pump fixing member 90 fixed to the bottom plate 31 in a state spaced apart from the vent hole 80 by a predetermined interval Is installed. As shown in FIG. 7, the pump fixing member 90 is formed through bending of an iron plate having a predetermined width. The pump fixing member 90 has a larger area than the plurality of ventilation holes 80 and is spaced apart from the upper part of the ventilation holes 80. Flat plate pump fixing portion 91 to be covered with the state, the support portion 92 is bent and extended from the ends of the pump fixing portion 91 by a predetermined length, and bent to extend in the horizontal direction again from the support portion 92 It consists of a fixing portion 93 fixed to the bottom plate 31 through the fastening or welding of the screw 94. And the oxygen supply pump 70 is fixed to the upper surface of the pump fixing portion (91).

This configuration is such that the pump fixing part 91 maintains a state spaced apart from the ventilation hole 80 so that the air flows through the openings on both sides thereof. In addition, such a configuration is such that the water splashing on the blades of the outside air circulation fan 23 in the process of operating the outside air circulation fan 23 of the lower heat exchange chamber 25 is scattered into the upper pump room 35 through the ventilation hole 80. When introduced, it is blocked by the pump fixing portion 91 of the pump fixing member 90 to protect the oxygen supply pump 70 from water.

In addition, the present invention, as shown in Figure 3, the oxygen discharge pipe 74 connected to the discharge port 72 of the oxygen supply pump 70 extends toward the indoor unit 10 via the oxygen generating chamber 34, oxygen A silencer 75 for preventing pulsation and noise from being transmitted toward the indoor unit 10 through the oxygen discharge pipe 74 by attenuating pulsation and noise transmitted from the oxygen supply pump 70 in the middle of the discharge pipe 74. Is installed. In addition, the silencer 75 is inserted and fixed to the shielding member 36 having a predetermined elasticity to attenuate the vibration transmitted from the oxygen supply pump 70.

The following describes the operation of the air conditioner with the oxygen generating function according to the present invention of this configuration.

When performing the normal cooling operation, the outdoor unit 20 performs heat exchange with the outdoor heat exchanger 22 in which the external air is relatively high temperature by the operation of the external air blowing fan 23 installed in the lower heat exchange chamber 25. , The indoor unit 10 performs the cooling of the indoor space by allowing the indoor air circulated by the internal circulation fan (not shown) to be discharged to the indoor space after heat exchange with the cold indoor heat exchanger (not shown).

When the oxygen supply is performed in addition to the cooling operation, the oxygen supply pump 70, the cooling fan 80, and the blower fan 44 of the oxygen generator 40 operate in the oxygen device chamber 30 above the outdoor unit 20. do. At this time, when the blowing fan 44 and the oxygen supply pump 70 of the oxygen generator 40 is operated, the air introduced through the outside air through hole 37 of the oxygen generating chamber 34 is the inlet of the oxygen generator 40 ( 42 flows into the outlet 43 and the oxygen is extracted from the air through the oxygen extractor 50 embedded in the oxygen generator 40.

As shown in FIG. 5, the oxygen extraction operation is performed by each oxygen extraction plate by the suction force of the oxygen supply pump 70 when the air introduced from the outside flows between the oxygen extraction plates 52 of the oxygen extractor 50. Oxygen in the air is extracted while passing through the oxygen filtration membrane 56 by the phenomenon that the pressure of the oxygen flow passage 53 inside the oxygen filtration membrane 56 of the 52 is lowered. That is, as the air passes through the oxygen filtration membrane 56, the oxygen diffusion in the air is performed by using a phenomenon in which the dissolution diffusion rate of the oxygen molecules is faster than the nitrogen molecules in the air. At this time, the extracted oxygen flows toward the oxygen discharge hole 54 through the oxygen flow path 53 of the oxygen extraction plate 52, and is subsequently sucked into the oxygen supply pump 70 through the oxygen suction pipe 73. In addition, the oxygen supply pump 70 supplies the extracted oxygen to the indoor unit 10 through the oxygen discharge pipe 74 so that oxygen can be supplied to the indoor air circulating. At this time, pulsation, noise and vibration generated from the oxygen supply pump 70 are attenuated through the silencer 75 provided in the middle of the oxygen discharge pipe 74.

In addition, as shown in FIG. 6, the oxygen supply pump 70 is pumped through the external air flow hole 38 on the side of the pump chamber 35 by the suction force of the external air circulation fan 23 installed in the heat exchange chamber 25. ) After being introduced into the inside of the pump chamber 35, the air is cooled by the air flowing toward the heat exchange chamber 25 through the ventilation hole 80 at the bottom of the pump chamber 35, thereby allowing cooling without a separate cooling fan. At this time, since water splashing from the lower heat exchange chamber 25 toward the ventilation hole 80 by the operation of the external air circulation fan 23 is blocked by the pump fixing member 90, the oxygen supply pump 70 may be protected from water. It becomes possible.

In addition, according to the present invention, the oxygen supply pump 70 is divided into the oxygen generating chamber 34 in which the pump chamber 35 and the oxygen generator 40 are installed by the shielding member 36 so that the heat of the oxygen supply pump 70 generates oxygen. Not only can it be prevented from being transferred to the seal 34, but the blower fan 44 installed at the outlet of the oxygen generator 40 blows the air after the oxygen extraction to the oxygen supply pump 70, so that the oxygen supply pump ( 70) to further increase the cooling efficiency.

As described above in detail, the air conditioner with the oxygen generating function according to the present invention is divided into a space in which the oxygen generator is installed and the heat exchange space of the outdoor unit, and further divided into a space in which the oxygen supply pump is installed, the surrounding heat is oxygen Since it is not transferred to the generator has an effect that can increase the oxygen generation efficiency.

In addition, the present invention is not only easy to troubleshoot the oxygen generator and oxygen supply pump because the oxygen equipment room is disposed on the outdoor unit, it is possible to prevent the risk of leakage due to their inundation.

In addition, the present invention is because the pump chamber partitioned with the heat exchange chamber communicates with the heat exchange chamber through the ventilation hole not only can cool the oxygen supply pump installed in the pump chamber by using the suction force of the outdoor air circulation fan for the outdoor unit, but also from the lower heat exchange chamber toward the ventilation hole. Since scattering water is blocked by the pump fixing member, the oxygen supply pump can be protected from water.
