Description

  The present invention relates to an air conditioner.

  An indoor unit of an air conditioner includes a heat exchanger, a fan, and the like in a casing having an inlet and an outlet. When the fan rotates, indoor air is sucked into the casing through the suction port and sent to the heat exchanger. In this heat exchanger, heat is exchanged between the refrigerant circulating in the interior and the air. Heat-exchanged and temperature-controlled air is supplied into the room through the casing outlet.

  In such an indoor unit, moisture in the air is condensed in the heat exchanger during cooling operation or dehumidifying operation, and drain water is generated. Therefore, a drain pan is disposed below the heat exchanger. However, if the heat exchanger is disposed so as to contact the upper surface of the drain pan, the heat exchanger may damage the drain pan.

  Therefore, in Patent Document 1, the heat exchanger is mounted on the upper side away from the drain pan, and an elastic sealing material made of, for example, foamed resin is disposed in the gap between the lower edge of the heat exchanger and the upper surface of the drain pan. An air conditioning apparatus is disclosed. This sealing material plays the role which suppresses the damage of a drain pan, and the role which plugs up the clearance gap between the lower edge part of a heat exchanger, and the upper surface of a drain pan. By closing the gap, it is possible to suppress a part of the air sucked into the casing from bypassing the gap without passing through the heat exchanger, and thus it is possible to suppress a decrease in the performance of the air conditioner.

JP 2007-240113 A

  However, in a structure such as Patent Document 1 in which the heat exchanger is mounted on the upper side away from the drain pan and the sealing material is disposed in the gap between the heat exchanger and the drain pan, the heat exchange is performed by the amount of shifting the heat exchanger upward. Since the chamber becomes smaller, there is a problem that the heat exchangeable area is reduced. This problem is not limited to the case of Patent Document 1 in which a sealing material is disposed in the gap between the lower edge portion of the heat exchanger and the upper surface of the drain pan. For example, the sealing material is attached to the upper edge portion of the heat exchanger and the casing. When the seal material is disposed in the gap between the lower surface of the top plate and the sealing material is disposed in the gap between the side edge of the heat exchanger and the inner surface of the side plate of the casing, the same occurs.

  Then, this invention is made | formed in view of this point, The place made into the objective is providing the air conditioning apparatus which can suppress that the area | region which can be heat-exchanged decreases.

  The air conditioner of the present invention includes a casing (17) having an inlet (13) and an outlet (15), and the casing (17). The casing (17) is arranged from the inlet (13). A heat exchanger (19) capable of exchanging heat between the air sucked into the refrigerant and the refrigerant flowing through the inside, and the edge portion in contact with the edge portion of the heat exchanger (19) so as to conduct heat. And a metal elastic member (31) disposed between the casing (17) and the inner surface. The elastic member (31) has a ventilation path that allows the air sucked into the casing (17) from the suction port (13) to flow to the outlet (15), and passes through the ventilation path. Heat exchange with air.

  In this configuration, the air flow is replaced by the gap between the edge of the heat exchanger (19) and the inner surface of the casing (17), which has been sealed with a sealing material made of foamed resin or the like as in the prior art. A metal elastic member (31) having a path is disposed. Since this elastic member (31) is made of metal and is in contact with the edge of the heat exchanger (19) in a state capable of conducting heat, the temperature is close to that of the heat exchanger (19). Thereby, the air can pass through the ventilation path of the elastic member (31) and heat can be exchanged between the air and the elastic member (31) when the air passes. Therefore, since the clearance gap between a heat exchanger (19) and the inner surface of a casing (17) can also be utilized for heat exchange, it can suppress that the area | region which can be heat-exchanged decreases.

  Further, the heat exchanger (19) disposed in the casing (17) may be warped, and due to this warp, the dimensions of the heat exchanger (19) may vary. In this configuration, the elastic member (31) disposed in the gap between the edge of the heat exchanger (19) and the inner surface of the casing (17) is elastically deformed, and the dimensional variation of the heat exchanger (19) is also affected. You can follow. Accordingly, even when the heat exchanger (19) is warped and the dimensions of the heat exchanger (19) vary, the elastic member (31) is connected to the edge of the heat exchanger (19) and the casing ( 17) It is arranged evenly so as to fit in the gap with the inner surface. Thereby, since the elastic member (31) can be spread over almost the entire gap between the edge of the heat exchanger (19) and the inner surface of the casing (17), the efficiency of heat exchange in the elastic member (31) is improved. It can control that it falls.

  The position where the elastic member (31) is disposed is not limited to the region between the lower edge of the heat exchanger (19) exemplified above and the upper surface of the drain pan (35). For example, the heat exchanger (19) ) Between the upper edge of the casing (17) and the lower surface of the top plate (17a), between the side edge of the heat exchanger (19) and the inner surface of the side plate (17d) of the casing (17). It may be an area.

  For example, the casing (17) has a top plate (17a), a bottom plate (17b), and a pair of side plates (17d), the heat exchanger (19) is supported by the pair of side plates (17d), and the elastic A member (31) is located between the upper edge of the heat exchanger (19) and the lower surface of the top plate (17a) and between the lower edge of the heat exchanger (19) and the upper surface of the bottom plate (17b). The form arrange | positioned by at least one between is mentioned.

  In this configuration, the side edges of the heat exchanger (19) can be stably supported by the pair of side plates (17d) of the casing (17), and the upper edge of the heat exchanger (19) and the top plate ( The elastic member (31) is disposed between at least one of the lower surface of 17a) and between the lower edge of the heat exchanger (19) and the upper surface of the bottom plate (17b). It can be used for heat exchange.

  The heat exchanger (19) includes a plurality of plate fins (41) arranged side by side, and a cross fin coil having a heat transfer tube (43) that passes through the plate fins (41) and through which the refrigerant flows. In the case of a heat exchanger (19) of the type, it is preferable that the elastic member (31) is disposed so as to be in contact with the heat transfer tube (43). Thereby, since the elastic member (31) can directly exchange heat with the heat transfer tube (43) through which the refrigerant flows, the efficiency of heat exchange with air in the elastic member (31) can be further improved. .

  Examples of the elastic member (31) include those composed of a plurality of fine metal wires that are rolled or bent and intertwined.

  The elastic member (31) having such a structure has elasticity (elasticity) because the metal thin wires are entangled with each other. In addition, this elastic member (31) has excellent air permeability and water permeability since almost all of the fine metal wires become an air flow path and a water flow path, and the direction of air flow and water flow is not limited to a specific direction. ing.

  Thus, when the elastic member (31) has excellent water permeability, the elastic member (31) is arranged between the lower edge of the heat exchanger (19) and the upper surface of the drain pan (35). It is good to be installed. That is, the air conditioner of the present invention is generated in the heat exchanger (19) interposed between the lower edge of the heat exchanger (19) and the upper surface of the bottom plate (17b) of the casing (17). When the drain pan (35) for storing drain water is further provided, the elastic member (31) has water permeability, and the lower edge of the heat exchanger (19) and the drain pan (35) It is preferable to be disposed between the upper surface.

  For example, when a sealing material made of foamed resin or the like is disposed between the lower edge of the heat exchanger (19) and the upper surface of the drain pan (35) as in the prior art, the sealing material can easily absorb water and retain water. Since the water permeability is not necessarily good, the sealing material temporarily blocks the drain water from flowing to the drainage mechanism such as a drain pipe that drains drain water or a drain pump that sucks and drains drain water. . When the drain water is temporarily blocked, the water level of the drain water rises in the drain pan (35), so that the lower part of the heat exchanger (19) may be caught by the drain water. As a result, since the lower part of the heat exchanger (19) exchanges heat with the drain water, the efficiency of heat exchange with air decreases.

  On the other hand, in this configuration, the elastic member (31) configured by a plurality of fine metal wires that are rolled or bent and intertwined is used, and the elastic member (31) is connected to the lower edge portion of the heat exchanger (19) and the drain pan ( 35), the flow of drain water to the drainage mechanism can be prevented from being blocked. Thereby, since it can suppress that the water level of drain water rises in a drain pan (35), it can suppress that the efficiency of heat exchange falls.

  The elastic member (31) preferably contains stainless steel or aluminum as a main component. These metals are excellent in elasticity, heat transfer, corrosion resistance and the like.

  As described above, according to the present invention, since the gap between the heat exchanger and the inner surface of the casing can also be used for heat exchange, it is possible to suppress a decrease in the heat exchangeable region.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
The air conditioner according to the present embodiment includes an indoor unit 11, an unillustrated outdoor unit, an unillustrated refrigerant pipe that connects these and circulates refrigerant. As shown in FIGS. 1 and 2, the indoor unit 11 is a ceiling-type indoor unit in which the top plate 17 a of the casing 17 is fixed to the ceiling surface T by the hanging bolts 33.

  In the indoor unit 11, a suction port 13 for sucking indoor air is provided in the bottom plate 17 b of the casing 17, and an air outlet 15 for blowing out air is provided on the front surface of the casing. A suction grill 13 a is attached to the suction port 13. A flap 23 for adjusting the direction of air blown from the blower outlet 15 is attached to the blower outlet 15 of the casing 17. The flap 23 is supported by the casing 17 via a rotation shaft 27 and is rotatable about the rotation shaft 27.

  In the casing 17, a blower 21 that sucks indoor air from the suction port 13 and blows out the air from the blower port 15 is disposed above the suction port 13. Various types can be used as the blower 21. For example, a centrifugal fan such as a sirocco fan has an advantage that air can reach farther.

  A switch box 37 is disposed between the back surface 17 c of the casing 17 and the blower 21. The switch box 37 includes a control unit (not shown) for controlling the blower 21, the flap 23, and the like, switches, and the like.

  A heat exchanger 19 is disposed in the space between the blower 21 and the outlet 15 in the casing 17, and a drain pan 35 is provided below the heat exchanger 19.

  As shown in FIGS. 2 and 3, the heat exchanger 19 has a flat shape extending in the width direction and the height direction of the casing 17 and having a thickness smaller than the width and height. The heat exchanger 19 is arranged such that its upper edge portion 19 a is in contact with the top plate 17 a of the casing 17 and its lower edge portion 19 b is separated from the upper surface of the drain pan 35 by a predetermined distance. Further, the heat exchanger 19 is disposed so as to be inclined with respect to the vertical direction so that the lower edge portion 19b is located closer to the back plate 17c (blower 21 side) than the upper edge portion 19a. As shown in FIG. 3, the heat exchanger 19 is supported by a pair of side plates 17 d of the casing 17 via support members 45 at the left and right side edge portions 19 c thereof.

  As shown in FIGS. 4 and 5, the heat exchanger 19 is a cross having a plurality of plate fins 41 arranged in parallel at a predetermined interval and a plurality of heat transfer tubes 43 passing through these plate fins 41. It is a fin coil type. The plurality of heat transfer tubes 43 are arranged such that the longitudinal direction of the heat transfer tubes 43 is substantially parallel to the width direction of the heat exchanger 19, and are arranged in the height direction and the thickness direction of the heat exchanger 19. Adjacent heat transfer tubes 43 are connected by a U-shaped tube 43a at the end in the width direction. The refrigerant flows in from one of the end 43b and the end 43c of the heat transfer tube 43 and flows out from the other.

  In the present embodiment, as shown in FIGS. 2, 3, and 5, the elastic member 31 is evenly disposed in almost the entire gap between the lower edge portion 19 b of the heat exchanger 19 and the upper surface of the drain pan 35. The elastic member 31 is in contact with the plate fins 41 of the heat exchanger 19 and can conduct heat between the plate fins 41. The elastic member 31 is formed by three-dimensionally intertwining a thin metal wire such as stainless steel or aluminum that is rounded or bent, and has a so-called metal scrubbing shape.

  Since the elastic member 31 is configured by entangled with the above-described thin metal wires, it has elasticity (elasticity). In addition, the elastic member 31 has excellent air permeability and water permeability since almost all of the thin metal wires become an air flow path and a water flow path, and the direction of air flow and water flow is not limited to a specific direction. .

  The elastic member 31 may be disposed after the drain pan 35 and the heat exchanger 19 are disposed in the casing 17 and then inserted into a gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35. Before the drain pan 35 or the heat exchanger 19 is arranged in the casing 17, it may be attached in advance to the upper surface of the drain pan 35 or the lower edge portion 19 b of the heat exchanger 19. Since the elastic member 31 has elasticity as described above and is flexible, it can be easily inserted into a narrow gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35, and after insertion. Is easy to fit into the opening shape of the gap. The elastic member 31 is preferably fixed to the lower edge portion 19b of the heat exchanger 19 or the upper surface of the drain pan 35 with an adhesive, a fixing member, or the like.

  In the case of this embodiment, air circulates through the elastic member 31 in the direction from the blower 21 toward the blowout port 15. Since the drain pan 35 is inclined downward from the outlet 15 side (front side) toward the drain pipe 47 side (back side), the drain water flows from the front side toward the back side. Accordingly, the drain water flows through the elastic member 31 in the drain pan 35 in the direction from the position on the outlet 15 side to the drain pipe 47 side with respect to the lower edge portion 19b of the heat exchanger 19.

  Next, the operation of the indoor unit 11 according to the present embodiment will be described. When a cooling operation, a heating operation, a dehumidifying operation, or the like of the air conditioner is started, the refrigerant flows through the heat transfer tube 43 of the heat exchanger 19 and the blower 21 is driven.

  When the blower 21 is driven, indoor air is sucked into the casing 17 from the suction port 13 and sent to the heat exchanger 19 side. This air passes through the gap between the plate fins 41 of the heat exchanger 19 and also passes through the elastic member 31.

  The air passing between the plate fins 41 is adjusted to a predetermined temperature by exchanging heat with the refrigerant, and supplied to the room from the outlet 15. Further, since the elastic member 31 is in contact with the plate fin 41 at the lower edge portion 19 b of the heat exchanger 19, the temperature is close to that of the plate fin 41. Therefore, the air passing through the inside of the elastic member 31 exchanges heat with the elastic member 31 and is supplied into the room from the outlet 15.

  Next, the flow of drain water when dew condensation occurs in the heat exchanger 19 as in the cooling operation, the dehumidifying operation, etc. will be described. During cooling operation, dehumidifying operation, and the like, water drops generated by the heat exchanger 19 having a low temperature and dew condensation on the surface thereof flow downward through the plate fins 41 and are collected in the drain pan 35. The drain water accumulated in the drain pan 35 is discharged to the outside through the drain pipe 47.

  First, for comparison, a case where a sealing material 61 made of foamed resin or the like is disposed in the gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35 will be described with reference to FIG. In this case, it cannot be said that this sealing material 61 absorbs drain water and retains it easily, and the water permeability is not necessarily good. Therefore, the sealing material 61 temporarily blocks the flow of drain water. When the drain water is temporarily blocked, the water level of the drain water rises in the drain pan, and the lower part of the heat exchanger 19 is caught by the drain water.

  On the other hand, in this embodiment, as shown in FIG. 5, the elastic member 31 is disposed in the gap between the lower edge portion 19 b of the heat exchanger 19 and the upper surface of the drain pan 35. Since this elastic member 31 has excellent water permeability and hardly retains water, drain water flows between the fine metal wires and flows smoothly from the outlet 15 side (front side) to the drain pipe 47 side (back side), and the drain pipe It is discharged to the outside through 47.

  As described above, according to the above embodiment, the gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35, which has been closed with a sealing material made of foamed resin or the like as in the prior art, Instead of the sealing material, a metal elastic member 31 having a ventilation path is provided. As a result, air can pass through the ventilation path of the elastic member 31 and air can exchange heat with the elastic member 31 when the air passes. Therefore, since the gap between the heat exchanger 19 and the inner surface of the casing 17 can also be used for heat exchange, it is possible to suppress the reduction of the heat exchangeable region.

  Further, in the above embodiment, the elastic member 31 disposed in the gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35 is elastically deformed to follow the dimensional variation of the heat exchanger 19. Accordingly, even when the heat exchanger 19 is warped and the dimensions of the heat exchanger 19 vary, the elastic member 31 remains in the gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35. Evenly arranged to fit. Thereby, since the elastic member 31 can be spread over almost the entire gap between the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan 35, it is possible to suppress a decrease in the efficiency of heat exchange in the elastic member 31. .

  In the above embodiment, the elastic member 31 is constituted by a plurality of fine metal wires that are rolled or bent and intertwined three-dimensionally. Therefore, the elastic member 31 has excellent air permeability and water permeability since almost all of the thin metal wires become the air flow path and the water flow path, and the direction of the air flow and the water flow is not limited to a specific direction. .

  Moreover, in the said embodiment, the said elastic member 31 comprised by the metal thin wire | round | yen which was rolled up or bent and was entangled three-dimensionally was used, and this elastic member 31 was used for the lower edge part of the heat exchanger 19, and the drain pan 35. It is arranged between the upper surface. Therefore, it is possible to prevent the drain water from flowing toward the drain pipe 47 from being blocked. Thereby, since it can suppress that the water level of drain water rises in the drain pan 35, it can suppress that the efficiency of heat exchange falls.

In the second embodiment, a part of the thin metal wire constituting the elastic member 31 is inserted between the plate fins 41. The fine metal wire inserted between the plate fins 41 is in contact with the heat transfer tube 43. Although FIG. 6 shows a form in which the tip of the metal thin wire is in contact with the lower surface of the heat transfer tube 43, for example, the metal thin wire may be disposed around the heat transfer tube 43.

  As described above, according to the second embodiment, since the elastic member 31 can directly exchange heat with the heat transfer tube 43 in which the refrigerant flows, the efficiency of heat exchange with the air in the elastic member 31 can be further improved. Can do.

The upper surface of the elastic member 31 is in contact with the lower ends of the plurality of plate fins 41. In the gap between the lower end portion of the plate fin 41 that is the lower edge portion 19b of the heat exchanger 19 and the upper surface of the drain pan, a plurality of the elastic members 31 are arranged along the width direction of the gap. Each elastic member 31 has a plurality of ventilation paths 31a through which air sucked into the casing 17 passes. The air passing through these ventilation paths 31 a exchanges heat with each elastic member 31. The ventilation path 31a also functions as a water passage.

  It is preferable that the lower end portion of the plate fin 41 is processed so that the inclination angle thereof is substantially parallel to the upper surface of the elastic member 31. Thereby, since the contact area of the lower end part of the plate fin 41 and the upper surface of the elastic member 31 becomes large, the heat conduction efficiency between the plate fin 41 and the elastic member 31 can be improved.
