Description

  The present invention relates to an air conditioner having a condensed water treatment mechanism.

  Conventionally, this type of air conditioner is provided with a water recovery unit in the grill to prevent the water generated in the scroll from being discharged to the outside of the grill as a treatment for the dew condensation water generated during the cooling operation (for example, Patent Documents). 1).

FIG. 3 shows a cross-sectional view of a main part of a conventional air conditioner described in Patent Document 1. As shown in FIG. 3, the grille 1, the scroll 2, the water recovery unit 3, the blowout unit 7, and the fan case 6 are configured. Depending on the usage conditions during cooling, the left and right blades (not shown) and the scroll 2 are cooled, and the generated dew condensation water travels along the scroll 2, and reaches the water recovery unit 3 provided between the scroll 2 front edge and the grill 1. A dew treatment mechanism is adopted in which water is absorbed and retained by a water absorbing material (not shown).

  However, in the conventional configuration, the water recovery unit that recovers the generated dew condensation water is a mechanism that recovers water in the gap with the grill ahead of the scroll front edge. Condensed water adhering to the surface is energized by gravity, etc., and flows forward through the scroll, so it does not enter the water recovery part below, but jumps out of the grill, and it may splash on the user or the room Had.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an air conditioner that reliably collects condensed water inside a grill.

  In order to solve the above-described conventional problems, the air conditioner of the present invention is provided with one or more convex ribs extending left and right inside the scroll.

  As a result, the water that has condensed in the scroll tends to flow forward through the scroll, but there is a rib inside the scroll, so there is no stagnation of the water, or the condensed water does not jump out of the grill to eliminate the momentum. It will be possible to reliably lead to the water recovery unit.

  The air conditioner of the present invention improves the reliability of the condensed water generated from the inside of the scroll at low cost by applying a simple shape to the scroll, and the condensed water is applied to the user and the room. A highly reliable air conditioner that can be prevented can be provided.

  Further, since ribs are formed inside the scroll, it is possible to prevent the occurrence of condensation on the grill or the like during cooling operation by preventing the entrainment of room air. Furthermore, it becomes a conspicuous structure of rib formation inside the scroll, and the design of the air conditioner body can be improved.

  According to a first aspect of the present invention, there is provided a frame that is integrally formed with the scroll, a blow-out portion, and a grill that forms an outer shell, and the scroll is provided by providing one or a plurality of convex ribs extending left and right inside the scroll. Condensed water that is about to flow forward through the pipe is once stagnated or lost momentum by the rib, so that the water can be surely guided to the water recovery section without splashing outside the grill in front of the main body. In addition, because the ribs are formed inside the scroll, it is possible to prevent the blowing air from being peeled off, so that the occurrence of condensation on the grill during cooling operation can be reduced, and the design of the indoor body can be improved due to an inconspicuous configuration. You can plan.

  In the second invention, in particular, by providing the rib of the first invention over almost the entire left and right width inside the scroll, it is ensured that water does not splash outside the grill in front of the main body regardless of where the condensation occurs in the scroll. It becomes possible to guide to the water recovery section.

  In the third aspect of the invention, in particular, by forming the rib of the first or second aspect of the invention in a substantially triangular cross section, the blown air is blown out along the rib during cooling operation. Comfort can be improved.

  In the fourth aspect of the invention, in particular, the rib of the third aspect of the invention is formed in a substantially triangular shape in cross section so that the blowing air rises in the blowing direction, so that the blowing air flows along the rib during cooling operation. Since the air is blown out, the feeling of cold wind is prevented and the comfort can be improved.

  In the fifth aspect of the invention, in particular, the rib of any one of the first to fourth aspects is integrally formed with the scroll, so that materials such as processing labor and adhesive are unnecessary and can be accurately produced at low cost. it can.

  In the sixth aspect of the invention, in particular, by providing one or more grooves extending left and right in the scroll according to any one of the first to fifth aspects, the water generated in the scroll is temporarily stored in the grooves. When the water is full, the scroll is slowly transmitted, and the water can be surely guided to the water recovery section without jumping out of the grill in front of the main body, so that the treatment capacity of condensed water is improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of main parts of an air conditioner according to the first embodiment of the present invention, and FIG. 2 is a plan view of main parts of the air conditioner according to the first embodiment of the present invention. .

  In FIG. 1 and FIG. 2, indoor air sucked from a suction port (not shown) by a crossflow fan (not shown) attached to the fan case 6 is converted into a frame 9 and an outer shell integrally formed with the scroll 2. Heat is exchanged inside the indoor unit consisting of the grill 1 that forms the air and is blown into the room from the blowing unit 7 along the scroll 2 to control the room temperature.

  During heat exchange, condensation occurs in the air conditioner, for example, the fan case 6 due to a temperature difference, particularly during cooling, and the accumulated condensed water flows forward through the scroll 2 and flows between the grill 1 and the scroll 2. It enters the water recovery unit 3 below the scroll 2 provided in the mating unit, and is absorbed and retained by a water absorbing material (not shown) or the like for water treatment.
