Description

  The present invention relates to a separation type air conditioner having an oxygen enrichment function.

  Conventionally, as this type of air conditioner, for example, an air conditioner with an oxygen enrichment function, including an oxygen enrichment unit including an outdoor unit including a heat exchanger, a blower fan, an oxygen enrichment film, An invention is disclosed in which the oxygen-enriched unit is placed on the upper surface of the outdoor unit and increases in the height direction but does not increase the installation space in the installation plane direction.

In the configuration of the above invention, a gas delivery pipe is used to convey the oxygen-enriched gas from the outdoor unit side to the indoor unit. In this invention, this delivery pipe is disposed on the upper surface of the outdoor unit. An example in which the unit is taken out directly from the outdoor unit casing and pulled to the indoor unit side is disclosed (for example, see Patent Document 1).
JP-A-5-99457

  However, in the conventional configuration, the connecting portion of the inner and outer connecting pipes is disposed below the side surface on the side surface of the outdoor unit, while the oxygen enrichment unit is disposed above the outdoor unit housing, and the gas delivery pipe is routed from this portion. It is configured to draw around. Now, in general, the inner and outer connecting pipes connecting the indoor unit and the outdoor unit are composed of two pipes having different diameters, and these two pipes are routed together to connect the indoor unit and the outdoor unit. Furthermore, an electric wire (not shown) that electrically connects the indoor unit and the outdoor unit for power supply and communication is also routed together with the internal and external connection pipes, and these are integrated from the indoor unit to the vicinity of the outdoor unit. Collected, taped and locked. Therefore, in the air conditioner according to the above-mentioned conventional invention, the connection position between the inner / outer connection pipe through which the refrigerant passes and the outdoor unit of the gas delivery pipe through which the oxygen-enriched gas passes is separated, and the inner / outer connection pipe and the gas delivery pipe are routed. In the case of branching in the middle of the outdoor unit, it is necessary to pull it up to the vicinity of the inner and outer connecting pipes of the outdoor unit and then pull it upward again. In addition, if the taping etc. are not given to the branched part, the problem on aesthetics or weather resistance will arise. However, such work is inconvenient because it takes time for construction.

  The present invention solves the above-described conventional problems, facilitates connection with the outdoor unit of the gas delivery pipe, improves workability, and improves the aesthetics.

  In order to solve the above-described conventional problems, the air conditioner with an oxygen enrichment function according to the present invention conveys the enriched gas to the inside of the cover that covers the connection portion of the inner and outer connection pipes on the side of the outer box of the outdoor unit. A joint for connecting a gas delivery pipe to the indoor unit is provided.

  As described above, according to the present invention, it is possible to easily joint the gas delivery pipe for transporting the oxygen-enriched air from the outdoor unit to the indoor unit, and to improve workability and aesthetics.

  Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1)
1 and 2 show the configuration of a separation type air conditioner having an oxygen enrichment function of the present invention.

  In the figure, the separation type air conditioner is composed of an outdoor unit 1 and an indoor unit 2, and an outdoor unit side is connected by a two-way valve 7a and a three-way valve 7b which are connected by an inner / outer connection pipe 10 so that refrigerant gas circulates. The indoor unit side is connected by a connecting portion 18b. The outdoor unit 1 includes a compressor 11, a heat exchanger 12, and a fan 13, and is a main constituent member of a gas enrichment apparatus that includes a gas enrichment membrane unit 31, a decompression pump 32, and the like across a chamber. Is provided. Moreover, the indoor unit 2 has the fan 21 and the heat exchanger 22, and the blower outlet 33 of the gas enrichment apparatus is provided.

On the other hand, the gas enrichment apparatus includes a gas enrichment membrane unit 31 having an oxygen enrichment membrane, and a decompression pump 32 that decompresses the secondary side of the gas enrichment membrane unit 31, and the outdoor unit is an outdoor unit. The joint portion 4 is connected to the gas delivery pipe 40 via the auxiliary tube 8. The gas delivery pipe 40 is configured such that air enriched in the outdoor unit connected to the lead tube 16 of the indoor unit at the connecting portion 18a is discharged from the outlet 33 of the indoor unit.
The outdoor unit 1 has connection parts 7a and 7b for connecting the high-pressure gas pipe and the low-pressure gas pipe of the inner and outer connection pipes on one side surface, respectively, and in the joint part 4 for connecting the gas delivery pipe 40 to the outdoor unit side, The gas delivery pipe mounting portion 4a of the joint portion is provided on the same surface as the side surface to which the two connection portions of the inner and outer connection pipes are attached, adjacent to the two connection portions of the inner and outer connection pipes. Therefore, even when an impact from the outside occurs, the joint portion is in a position where it is difficult to hit and is hardly damaged.

  Next, the structure which can convey and discharge | emit oxygen-enriched air from an outdoor unit to an indoor unit using gas delivery piping is demonstrated using FIG. 1 and FIG.

  The lead tube 16 is connected to the gas delivery pipe 40 and the indoor unit 2 side to guide the oxygen-enriched gas to the indoor side with the connection direction of the gas delivery pipe 40 being substantially the same direction as the connecting portion of the inner / outer connection pipe 10. The gas delivery pipe 40 is connected to the outdoor unit side joint 4 at the distal end of the gas delivery pipe 40 connected to the lead tube 16. The joint 4 and the gas delivery pipe 40 can be easily connected by providing the L-shaped connector 5 at the distal end of the gas delivery pipe 40 on the outdoor unit side.

  The joint portion 4 is adjacent to the connecting portion between the high pressure gas pipe and the low pressure gas tube of the inner / outer connecting pipe 10, but the inner / outer connecting pipe 10 is prevented by adhesion of water droplets from the connecting portion of the inner / outer connecting pipe 10. It may be close to the upper part of.
