Description

  The present invention relates to an integrated air conditioner, and more particularly to an integrated air conditioner that has an indoor heat exchanger and an outdoor heat exchanger in a main body and can effectively use drain water.

  In general, in an air conditioner, condensed water is generated on the outer surface of the pipe wall of the indoor heat exchanger during cooling. This condensed water is discharged to the outside as drain water. In a conventional integrated air conditioner, drain water is temporarily stored in the base pan so that it does not leak into the room, and the drain water is drained to the outdoor side through a notch or a drain valve provided in the base pan. It had been.

  On the other hand, the drain water is effectively used to improve the energy efficiency of the refrigeration cycle. In other words, various measures to improve the cooling efficiency of the outdoor heat exchanger by guiding the drain water generated in the indoor heat exchanger during cooling to the outdoor heat exchanger and taking the heat of the outdoor heat exchanger. Has been made.

  As a configuration for guiding such drain water to the outdoor heat exchanger, for example, a configuration provided with a slinger ring has been proposed (see, for example, Patent Document 1). FIG. 4 is a side view schematically showing a configuration of a conventional integrated air conditioner having a slinger ring. FIG. 5 is a diagram schematically showing the configuration viewed from the direction of arrow A0 in FIG.

Referring to FIGS. 4 and 5, the conventional integrated air conditioner 120 has an indoor heat exchanger and an outdoor heat exchanger 105 in the main body 110. The illustration of the exchanger is omitted. During the cooling operation, the drain water 30 collected in the base pan 107 is scraped up by a slinger ring 103 attached to the outer periphery of the propeller fan 102 to form large droplets. Evaporates by being sprayed onto the container.

  In the configuration of a conventional integrated air conditioner having a slinger ring, as shown in FIG. 5, the drain water 30 raked upward by the slinger ring 103 is the top of the air guide plate 101 positioned above the slinger ring 103. It also scatters and adheres to the plate 101a. The water droplets of the drain water 30 adhering to the top plate 101a of the air guide plate 101 merely wastefully falls on the base pan 107, and most of them do not adhere to the outdoor heat exchanger 105 and cannot be used effectively. There was a problem.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to effectively improve the cooling efficiency of the outdoor heat exchanger during cooling operation by effectively using drain water attached to the top plate. It is to provide an integrated air conditioner.

  An integrated air conditioner of the present invention is an integrated air conditioner having an indoor heat exchanger and an outdoor heat exchanger in a main body, and includes a fan, a scraping member, and a guide member. . The fan faces the outdoor heat exchanger. The scraping member is for scraping the drain water accumulated in the main body by rotating together with the fan. The guide member is disposed above the scraping member and the outdoor heat exchanger, and attaches the water droplets of the drain water scattered upward by the scraping member, and the water droplets from above the scraping member to the outdoor heat exchanger. Inclined to guide.

  According to the integrated air conditioner of the present invention, the guide member is inclined so as to guide the water droplets of the drain water splashed upward by the scraping member from above the scraping member to the outdoor heat exchanger. Thereby, it is possible to use the water droplets of the drain water scattered upward to cool the outdoor heat exchanger, and the cooling efficiency of the outdoor heat exchanger during the cooling operation is improved.

  In the above integrated air conditioner, preferably, the guide member is inclined so as to become lower from the scraping member side toward the outdoor heat exchanger side.

The motor 4 is for applying a driving force to the propeller fan 2 and the slinger ring 3 for rotation. The base pan 7 is disposed in the lower part of the outdoor space and is for collecting the drain water 30. The slinger ring 3 is disposed so as to be immersed in the drain water 30 stored in the base pan 7 and so that the drain water 30 in the base pan 7 can be scraped up by the rotation of the slinger ring 3.

  The air guide plate 1 is disposed in the outdoor space of the main body 10 and is used to arrange and guide the air flow from the propeller fan 2 to the outdoor heat exchanger 5. The air guide plate 1 includes a top plate 1a, an opening 1b, and a bell mouth 1c. A propeller fan 2 is disposed in the opening 1b, and a bell mouth 1c is provided so as to surround the opening 1b. The top plate (guide member) 1a is disposed above the slinger ring 3 and the outdoor heat exchanger 5, and attaches water droplets of the drain water 30 scattered upward by the slinger ring 3, and the water droplets are slunger. It inclines so that it may guide to the outdoor heat exchanger 5 from the upper direction of the ring 3.

  A seal member 12 is provided between the outdoor heat exchanger 5 and the top plate 1 a of the air guide plate 1. The seal member 12 seals the flow of wind between the outdoor heat exchanger 5 and the top plate 1a. The seal member 12 may have a heat insulating function. The seal member 12 may be arranged and configured so that water droplets of the drain water 30 guided by the top plate 1a of the air guide plate 1 reach the outdoor heat exchanger 5 through the seal member 12.

  The sirocco fan 8 is arranged in the indoor space of the main body 10 so as to face the indoor heat exchanger 6. The motor 9 is for applying a driving force to the sirocco fan 8 for rotation.

  As shown in FIG. 1, the top plate 1a of the air guide plate 1 is inclined so as to become lower from the upper side of the slinger ring 3 to the upper side of the outdoor heat exchanger 5 (in the direction of arrow B1 in the figure). In addition, as shown in FIG. 2, the longitudinal direction of the outdoor heat exchanger 5 (in the direction of arrow B2 in the figure) also decreases toward the uppermost rotation direction of the propeller fan 2 (in the direction of arrow C in FIG. 2). It is inclined to. As shown in FIG. 1, the inclination angle θ1 of the top plate 1a with respect to the top plate of the main body 10 in the direction from the slinger ring 3 to the outdoor heat exchanger 5 (the direction of arrow B1 in the figure) is 3 ° or more and 7 ° or less. Is preferred. In addition, as shown in FIG. 2, the inclination angle θ2 of the top plate 1a with respect to the top plate of the main body 10 in the longitudinal direction of the outdoor heat exchanger 5 (the direction of arrow B2 in the figure) is preferably 3 ° or more and 5 ° or less.

  Although not shown, the outdoor heat exchanger 5 and the indoor heat exchanger 6 are connected to the compressor by piping, and the refrigerant flowing in the piping is used for the outdoor heat exchanger 5 and the indoor heat exchange. Refrigerating cycle operation is possible by cyclically evaporating and condensing in the vessel 6.

Next, the operation | movement at the time of the cooling operation of the integrated air conditioner of this Embodiment is demonstrated.
During the cooling operation in the above refrigeration cycle motion, the indoor heat exchanger 6 absorbs heat as an evaporator on the indoor side. For this reason, the air introduced from the room by the action of the sirocco fan 8 is cooled by the indoor heat exchanger 6 and then released into the room. At this time, in the indoor heat exchanger 6, condensed water is generated by the condensation of water vapor in the air. At the same time, since the outdoor heat exchanger 5 radiates heat as a condenser on the outdoor side, the air taken in from the outdoor by the propeller fan 2 is warmed by the outdoor heat exchanger 5 and then sent out to the outdoor.

  At this time, the condensed water generated in the indoor heat exchanger 6 is discharged as drain water 30 to the base pan 7. When the drain water 30 accumulated in the base pan 7 reaches a certain water level, it is scraped up by the slinger ring 3 provided on the outer peripheral portion of the propeller fan 2, and a part thereof is directly applied to the outdoor heat exchanger 5. Cooling of the outdoor heat exchanger 5 is promoted.

  Further, the water droplets of the drain water 30 that have been scraped upward by the slinger ring 3 and attached to the top plate 1a of the air guide plate 1 are located above the slinger ring 3 by the inclination of the top plate 1a as shown by the thick arrows in FIG. To the outdoor heat exchanger 5 and is applied to the outdoor heat exchanger 5. Thereby, cooling of the outdoor heat exchanger 5 is further promoted.

Next, the effect of the integrated air conditioner of this Embodiment is demonstrated.
According to the integrated air conditioner 20 of the present embodiment, as shown in FIG. 1, the top plate 1 a of the air guide plate 1 scatters water droplets of the drain water 30 scattered and adhered upward by the slinger ring 3. It inclines so that it may guide to the outdoor heat exchanger 5 from above. Thereby, the water droplets of the drain water 30 scattered upward can be used for cooling the outdoor heat exchanger 5, and the cooling efficiency of the outdoor heat exchanger 5 during the cooling operation is improved.

  Further, as shown in FIG. 3, the top plate 1a of the air guide plate 1 is inclined so as to become lower from the slinger ring 3 side toward the outdoor heat exchanger 5 side (in the direction of arrow B1 in the figure). Also in the longitudinal direction (arrow B2 direction) of the outdoor heat exchanger 5, the outdoor heat exchanger 5 is inclined so as to become lower toward the uppermost rotation direction (arrow C direction) of the propeller fan 2. For this reason, the water droplets of the drain water adhering to, for example, the point P of the top plate 1a of the air guide plate 1 are entirely in the longitudinal direction of the outdoor heat exchanger 5 along the top plate 1a as shown by the thick arrows in the figure. Can be applied evenly, and the entire longitudinal direction of the outdoor heat exchanger 5 can be uniformly cooled.

  Further, as shown in FIG. 3, the inclination angle θ1 of the top plate 1a with respect to the top plate of the main body 10 in the direction from the slinger ring 3 to the outdoor heat exchanger 5 (the direction of arrow B1 in the figure) is 3 ° or more and 7 ° or less. The inclination angle θ2 of the top plate 1a with respect to the top plate of the main body 10 in the longitudinal direction of the outdoor heat exchanger 5 (in the direction of arrow B2 in the figure) is 3 ° or more and 5 ° or less. When the inclination angles θ1 and θ2 are less than 3 °, the water droplets of the drain water 30 attached to the top plate 1a of the air guide plate 1 may not flow to the outdoor heat exchanger 5 side. When the inclination angle θ1 exceeds 7 ° and the inclination angle θ2 exceeds 5 °, the speed at which the water droplets of the drain water 30 flows down the top plate 1a becomes too high, and the entire length of the outdoor heat exchanger 5 in the longitudinal direction is increased. There is a possibility that the drain water 30 cannot flow uniformly. The inclination angles θ1 and θ2 may be the same angle or different from each other.

  Further, since the top plate 1a of the air guide plate 1 for adjusting and guiding the air flow from the propeller fan 2 to the outdoor heat exchanger 5 is used as a guide member for guiding the water droplets of the drain water, it is integrated air conditioning. The configuration of the machine 20 can be simplified and an increase in the number of parts can be prevented.

  In the present embodiment, the case where the top plate 1a of the air guide plate 1 is inclined as a guide member has been described. However, the top plate of the main body 10 is inclined as the guide member like the top plate 1a of the air guide plate 1 You may do it. In this case, the integrated air conditioner 20 is configured such that water droplets of the drain water 30 scraped up by the slinger ring 3 adhere to the top plate of the main body 10.

  In the present embodiment, the case where the slinger ring 3 is used as the scraping member has been described. However, the scraping member does not have to be ring-shaped, can be rotated together with the propeller fan 2, and the guide member has drain water. Any shape that can scrape and attach 30 can be used.

  Further, in the present embodiment, the propeller fan 2 has been described as a fan for cooling the outdoor heat exchanger 5. However, this fan can be used as long as it can cool the outdoor heat exchanger 5 by rotation. A good fan.

  Moreover, although the case where the top plate 1a of the air guide plate 1 is inclined with respect to the top plate of the main body 10 as the guide member has been described, the guide member is set with respect to the horizontal plane when the integrated air conditioner 20 is used. What is necessary is just to be comprised so that it may incline as mentioned above.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
