(Embodiment 1)
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIGS. 1-4, the suction inlet 1 is provided in the side surface of the main body 3, the blower outlet 2 is provided in the top | upper surface, and the support tool 9 is arrange | positioned horizontally so that the inside of the main body 3 may be divided up and down. .

  A refrigeration cycle comprising a compressor 4, an evaporator 5, a condenser 6, and a capillary tube 7 and a blower 8 for ventilating between the evaporator 5 and the condenser 6 are placed on the support 9 and separated. The arranged evaporator 5 and condenser 6 are connected by a capillary tube 7.

  The support 9 is integrally formed with a water receiving tray 10 disposed below the evaporator 5, and the water receiving tray 10 surrounds the lower wall of the evaporator 5 so as to surround the dew condensation water guiding means 13. Is standing.

  The surrounding wall 13 includes a pair of support ribs 11a and 11b arranged on the left and right side surfaces of the evaporator 5, and a pair of water receiving ribs that are erected in the vicinity of the lower ends of the front side and the back side of the evaporator 5. 12a and 12b.

  The support rib 11a and the support rib 11b support the evaporator 5 in a vertical state in a state of being floated on the upper portion of the water tray 10 by holding the copper tube portions 5a protruding on both side surfaces of the evaporator 5. .

  The two ends of the water receiving rib 12a on the front side of the main body 3 are cut by about 10 mm to form end ventilation portions 12c between the supporting rib 11a and the supporting rib 11b, and the water receiving ribs 12a and 12b. The central portion is cut by 15 mm to 20 mm to form a central ventilation portion 12d.

  The bottom surface of the water tray portion 10 is formed with an inclined surface 19a and an inclined surface 19b inclined toward the central ventilation portion 12d, a condensation drainage port 16 is provided on the bottom surface of the central ventilation portion 12d of the rear water reception rib 12b, and preliminary condensation The drain port 17 is erected in the vicinity of the condensation drain port 16 and in the central ventilation portion 12d. Here, when the air is blown to the evaporator 5 by the blower 8, air enters the surrounding wall 13 from the end ventilation portion 12c and the central ventilation portion 12d on the water receiving rib 12a side located on the windward side, and on the leeward side. Air comes out of the surrounding wall 13 from the central ventilation part 12d on the water receiving rib 12b side. That is, the air in the surrounding wall 13 flows from both ends, which are the end ventilation portions 12c, to the central portion, which is the central ventilation portion 12d.

  The evaporator 5 includes a plurality of vertically long fins 5b extending in the vertical direction, and these fins 5b are provided with a plurality of holes. A cylindrical copper tube portion 5a is fitted into the hole, and a plurality of fin portions 5b are arranged in parallel with a predetermined distance. That is, the surfaces of the fin portions 5b are arranged facing each other. The air sucked from the suction port 1 of the main body 3 by the blower 8 is parallel to the surface of the fin portion 5b of the evaporator 5, that is, along the surface of the fin portion 5b between the surfaces of the fin portion 5b. So that it is blown.

  The integrated air conditioner of this embodiment includes a normal operation and an internal drying operation. In the normal operation, since the refrigeration cycle and the blower 8 are operated, in the evaporator 5, the air blown by the blower 8 is cooled on the surface of the fin portion 5 b, and condensation is always generated in the fin portion 5 b of the evaporator 5. The condensed water condensed on the fin portion 5b becomes water droplets and travels through the fin portion 5b and adheres to the lower end of the fin portion 5b. In this state, new condensed water condensed on the fin portion 5b further flows as a water droplet through the fin portion 5b to the lower portion of the fin portion 5b. The water droplets of this new condensed water are combined with the water droplets already accumulated at the lower end, and a part of the combined water droplets are dropped from the fin portion 5b, but a part of the combined water droplets are attached to the lower end. Become.

  On the other hand, in the internal drying operation, after the normal operation, the refrigeration cycle is stopped and only the blower 8 is operated. Since the refrigeration cycle is not operated, the surface tension of the condensed water droplets adhering to the lower end portion of the evaporator 5 is balanced, and the condensed water guiding means (enclosure wall 13) and the passing air 18 alone are at the lower end portion of the evaporator 5. It was difficult to smoothly drop the condensed water droplets adhering to the water receiving tray 10.

  In order to drip this water droplet, it has a plurality of plate-shaped protrusions 14 extending upward from the water receiving tray 10 in the surrounding wall 13 as residual water guiding means, and the tips of the protrusions 14 of the evaporator 5 It contacts the lower end. Specifically, a plurality of plate-shaped protrusions 14 are provided on the inner surface of the water receiving rib 12 b, and the tips of the protrusions 14 come into contact with the lower ends of the fin portions 5 b of the evaporator 5.

  Thereby, the balance of the surface tension of the condensed water droplets adhering to the lower end portion of the fin portion 5b of the evaporator 5 is broken, and the lower end of the fin portion 5b of the evaporator 5 is also obtained during the internal drying operation only of the blowing operation. By providing the remaining water guide means for efficiently dropping the condensed water droplets adhering to the water receiving tray portion 10, the lower end portion of the fin portion 5 b of the evaporator 5 can be made dry.

  Further, the end of the protrusion 14 has an inclined end 15a and an inclined end 15b whose two ends are inclined downward. Specifically, the tip of the protrusion 14 has a triangular shape, and the triangular corner contacts the lower end of the fin portion 5 b of the evaporator 5. Thereby, the balance of the surface tension of the condensed water droplets adhering to the lower end portion of the evaporator 5 is broken, and the water receiving tray portion 10 is smoothly moved along the two inclined end portions 15a and 15b. Condensed water can be efficiently dropped to the bottom. In addition, since the corner | angular part between the inclination edge part 15a and the inclination edge part 15b contacts the fin part 5b, a contact area is small and the vibration of the evaporator 5 is hard to be transmitted to the water tray part 10 via the projection part 14. FIG. it can.

  In addition, at least a part of the tip of the protrusion 14 is provided above the upper end of the surrounding wall. In other words, a gap is provided between the upper end of the surrounding wall 13 and the lower end of the fin portion 5b in the vertical direction, and this gap has at least a part of the tip of the protrusion 14. As a result, the condensed water droplets adhering to the lower end portion of the fin portion 5b are blown by the air flowing through the gap between the upper end of the surrounding wall 13 and the lower end portion of the fin portion 5b. Breaks the balance of surface tension of adhering condensed water droplets, and smoothly drops condensed water to the bottom surface of the water receiving tray 10 smoothly along the two inclined end portions 15a and 15b. Can be made. In addition, the dimension of the clearance gap between the upper end of the surrounding wall 13 and the lower end part of the fin part 5b is larger than the dimension of the surface of the fin part 5b, and the surface of the fin part 5b. Thereby, ventilation becomes easy to flow through the clearance gap between the upper end of the surrounding wall 13 and the lower end part of the fin part 5b.

  Further, at least a part of the tip of the protrusion 14 is provided above the lower end of the evaporator 5. That is, at least a part of the tip of the protruding portion 14 is in contact with the fin portion 5b between the surface of the fin portion 5b and the surface of the fin portion 5b. Thereby, since the front-end | tip of the projection part 14 also contacts the dew condensation water which does not fall to the lower end with the dew condensation water between the surface of the fin part 5b and the surface of the fin part 5b, dew condensation water can be dropped early. .

  The evaporator 5 has a plurality of plate-shaped fins extending in the vertical direction, and the end of the tip of the protrusion 14 and the end of the lower end of the fin of the evaporator 5 are at a predetermined angle in the horizontal plane. It is what has. That is, since the end of the tip of the protrusion 14 and the end of the lower end of the fin of the evaporator 5 are not parallel in the horizontal plane, they are adjacent to each other between the surface of the fin 5b and the surface of the fin 5b. At least a part of the tip of the protruding portion 14 is in contact with the two fin portions 5b. As a result, the condensed water between the inner surfaces of the two adjacent fin portions 5b comes into contact with the condensed water that does not fall to the lower end, so that the condensed water can be quickly dropped, Condensed water that has flowed down from the outer surface of the two adjacent fin portions 5b to the lower end also breaks the balance of the surface tension of the condensed water droplets, and allows the condensed water to fall more efficiently.

  As shown in FIGS. 5 and 6, the protruding portion 14 extends from the surrounding wall 13 so as to incline toward the leeward side in the blowing direction of the air flowing through the surrounding wall 13. As a result, water droplets adhering to the windward surface of the air flowing in the surrounding wall 13 of the protrusion 14 are easily moved to the blowing direction of the air flowing in the surrounding wall 13, that is, to the end of the protrusion 14 on the leeward side. As a result, it becomes easy to fall on the water tray part 10 from the projection part 14.

  Further, the bottom surface of the water tray portion 10 has an inclined surface 19a and an inclined surface 19b, and the direction from the upper side to the lower side of the inclined surface 19a and the inclined surface 19b and the blowing direction of the air flowing in the surrounding wall 13 are defined. The same. As a result, the water droplets accumulated at the base of the windward surface of the air flowing in the surrounding wall 13 of the protruding portion 14 do not remain on the bottom surface portion where the protruding portion 14 and the water receiving tray portion 10 are in contact with each other. 16 to the drain tank 12.

  Further, when the passing air 18 passes through the end ventilation portion 12c, both the effect of forcing the condensed water on the water tray portion 10 in the central direction and the inclined surfaces 19a and 19b on the bottom surface of the water tray portion 10 are predetermined. By having an angle, the condensed water does not stay at the bottom surface portion where the projection 14 and the water receiving tray 10 are in contact with each other, and flows smoothly along the inclined surfaces 19a and 19b, and drains from the dew condensation outlet 16. Guided to the tank 12.

  It should be noted that hydrophilic means is provided at the end of the tip of the protrusion 14. By adding hydrophilic means to the end of the tip of the protrusion 14, it is possible to further enhance the effect of breaking the balance of the surface tension of the condensed water droplets adhering to the lower end of the evaporator 5. One example of the hydrophilic means is one having irregularities on the surface.

  The results of the actual internal drying test are as follows. The internal drying operation was carried out for about 1 hour in an environmental test room of approximately 6 tatami mats with a room temperature of 27 degrees Celsius and a humidity of 50%. The amount of residual water adhering to the evaporator 5 at the start of drying: 72 g is the amount of residual water adhering to the evaporator 5 at the end: 26 g, and the drying rate is about 64%. (No hydrophilic means added to the end of the tip of the protrusion 14) is the amount of residual water adhering to the evaporator 5 at the start of internal drying: 72 g, the amount of residual water adhering to the evaporator 5 at the end: 21 g Thus, the drying rate is about 70%, and the efficiency is increased by about 9%. The invention test product 2 (with hydrophilic means added at the end of the tip of the protrusion 14) is attached to the evaporator 5 at the start of internal drying. The amount of remaining water: 72g is the amount of remaining water adhering to the evaporator 5 at the end: 13g, and the drying rate is about 82% About 28% efficiency UP to effect was obtained.

  As described above, there is provided residual water guide means for efficiently dropping the condensed water droplets adhering to the lower end portion of the evaporator 5 to the water receiving tray portion even when the condensed water supply during the air blowing operation and the internal drying operation is lost. Thereby, the lower end part of the evaporator 5 can be made into a dry state.

  According to the present invention, a refrigeration cycle and a blower comprising a compressor, an evaporator, a condenser, and a capillary tube provided in the main body, the evaporator connected to the capillary tube, and a support that supports the condenser The water receiving tray portion disposed in the lower portion of the evaporator provided in the support, and the surrounding wall is provided in the water receiving tray portion as the dew condensation water guiding means at the lower end of the evaporator. It is formed by a pair of support ribs that are supported above the water tray portion on both sides of the evaporator and a pair of water receiving ribs that are erected in the vicinity of the lower end of the evaporator, and serves as a residual water guide means. A plurality of plate-shaped protrusions extending upward from the water tray in the surrounding wall, and the tips of the protrusions contact the lower end of the evaporator.

  As a result, since the tip of the protrusion comes into contact with the lower end of the evaporator, the balance of the surface tension of the condensed water droplets adhering to the lower end of the evaporator is broken, and the condensed water supply during the internal drying operation only in the air blowing operation is prevented. Providing an integrated air conditioner that makes the lower end of the evaporator dry by providing residual water guiding means that efficiently drops condensed water droplets adhering to the lower end of the evaporator to the water receiving tray even when it runs out It can also be used for air conditioning equipment such as dehumidifiers and air conditioners.
