[0045] An air conditioner 1 and the like according to an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the following examples but includes all modifications within the scope of the claims and their equivalents.

[0046] (First Embodiment)

[0047] Hereinafter, embodiments will be described with reference to the drawings. Figure 1 1 is a schematic side sectional view showing one structural example of the air conditioner 1 according to the embodiment. Figure 2 It is a perspective view showing the front portion of the appearance of the air conditioner 1 . Figure 3 It is a perspective view showing the rear portion of the appearance of the air conditioner 1 . Figure 4 It is a perspective view showing the lower portion of the appearance of the air conditioner 1 . Figure 1 The cross section of the air conditioner 1 as viewed from the front is schematically shown. Figure 1 In FIG. 1 , the placement state of the air conditioner 1 is represented as the normal use state of the air conditioner 1 to indicate up, down, left, and right. Figure 2 , Figure 3 , Figure 4 In the embodiment, the placement state of the air conditioner 1 is used as the normal use state of the air conditioner 1 to represent up and down and front and back and left and right. In this embodiment, the vertical direction represents the up and down direction. The first horizontal direction represents the left and right direction. The second horizontal direction represents the front and back direction.

[0048] The air conditioner 1 is mounted on a commercial vehicle such as a forklift, a truck, a tractor, an aerial work vehicle, a small excavator, a golf cart, and the like. When the air conditioner 1 is placed on a mobile body such as a forklift, the power of the main body of the air conditioner 1 can be turned on and off in conjunction with the turning on and off of the key switch of the engine of the forklift. That is, the power of the air conditioner 1 can be turned on by turning on the engine of the forklift, and the power of the air conditioner 1 can be turned off by turning off the engine of the forklift.

[0049] The housing 10 is a rectangular box made of resin or metal, and has a body 11 and a door 12 that can be opened and closed relative to the body 11. The housing 10 forming the box has an upper surface, a lower surface and side walls. The side walls include a first side wall 111, a second side wall 112, a third side wall 113 and a fourth side wall 114. In the present embodiment, the first side wall 111 is equivalent to the rear side wall. The second side wall 112 is equivalent to the front side wall. The third side wall 113 is equivalent to the right side wall. The fourth side wall 114 is equivalent to the left side wall. Therefore, the first side wall 111 and the second side wall 112 are opposite to each other. The third side wall 113 and the fourth side wall 114 are opposite to each other. The third side wall 113 connects the first side wall 111 and the second side wall 112. The fourth side wall 114 connects the first side wall 111 and the second side wall 112. The first side wall 111 is composed of a body-side first side wall 1111 and a door-side first side wall 1112.

[0050] The door 12 is disposed above the body 11 and is configured to be openable and closable relative to the body 11. Specifically, the door-side first side wall 1112 is connected to the body-side first side wall 1111 via two support portions 115. The support portion 115 may be a hinge, for example.

[0051] A concave handle portion 118 is formed from the lower portion to the lower surface of each of the third side wall 113 and the fourth side wall 114 of the casing 10. The handle portion 118 is a portion that is gripped by a user when carrying the air conditioner 1.

[0052] A duct 431 for blowing out the supply air is arranged on the upper surface of the housing 10. A water tank 8 is arranged next to the second side wall 112 of the housing 10. A water tank platform 116 for arranging the water tank 8 is located below the second side wall 112 of the housing 10. The water tank 8 covers the second side wall 112 by being arranged on the water tank platform 116. A drainage path 781 for draining water from the drain pan 6 described later is provided below the water tank platform 116. The water tank 8 is mounted on the housing 10 in a removable manner. The water tank 8 has a gripping portion and can be removed from the housing 10. When refilling water to the water tank 8, the water tank 8 can be taken to the tap of the water pipe, thereby reducing the workload of the user of the air conditioner 1 to refill water. A water level confirmation window 82 extending in the longitudinal direction is arranged on the side surface of the water tank 8. The user can visually confirm the remaining water amount in the water tank 8 through the water level confirmation window 82.

[0053] An air supply suction port 42 and an exhaust suction port 52 for sucking air of the air-conditioned space are formed on the casing 10. An air supply blow-out port 43 and an exhaust blow-out port 53 are also formed on the casing 10. The air supply suction port 42 is formed on the third side wall 113 of the casing 10. The exhaust suction port 52 is formed on the door 12 constituting a part of the casing 10. The air supply blow-out port 43 is formed on the upper surface of the casing 10 and is connected to the duct 431. The duct 431 may have a wind direction adjustment plate 432 that can rotate in the circumferential direction of the air supply blow-out port 43 to adjust the wind direction of the supply air blown out from the duct 431. The exhaust blow-out port 53 is formed on the fourth side wall 114 of the casing 10.

[0054] The air conditioner 1 has a water tank 8 for storing water and a cooling unit 20, and the cooling unit 20 includes a vaporization filter 2 and a sensible heat exchanger 3 to which water is supplied from the water tank 8. The vaporization filter 2 is contained in a vaporization filter housing 22. The sensible heat exchanger 3 is contained in a heat exchange housing 34. The vaporization filter housing 22 and the heat exchange housing 34 will be described in detail later. The vaporization filter 2 uses the vaporization heat of the water supplied from the water tank 8 to lower the ambient temperature and cool the air-conditioned space. The sensible heat exchanger 3 uses the sensible heat and latent heat of the water supplied from the water tank 8 to lower the ambient temperature and cool the air-conditioned space. The sensible heat exchanger 3 is an example of a heat exchanger. The vaporization filter 2 is arranged on the downstream side of the sensible heat exchanger 3 in the flow direction of the supply air. That is, the vaporization filter 2 is arranged between the sensible heat exchanger 3 and the supply air outlet 43.

[0055] The air cooled in two stages by the sensible heat exchanger 3 and the vaporization filter 2 is blown out as supply air from the supply air outlet 43 to the air-conditioned space. In addition, when passing through the sensible heat exchanger 3, the water supplied to the sensible heat exchanger 3 is cooled, and the air that has undergone sensible heat exchange with the supply air in the sensible heat exchanger 3 is blown out as exhaust air from the exhaust air outlet 53 to the outside of the air conditioner 1.

[0056] The air supply inlet 42 and the air supply outlet 43 are connected, and the air supply inlet 42 is used as the inlet of the air supply, and the air supply outlet 43 is used as the outlet of the air supply, thereby forming a supply air flow path 4 in which the air as the supply air flows. That is, the supply air flows into the supply air flow path 4 from the air supply inlet 42 and flows out from the air supply outlet 43. A dust collection filter for the supply air that captures dust of the supply air sucked from the air supply inlet 42 can be arranged at the air supply inlet 42.

[0057] The exhaust air intake port 52 and the exhaust air outlet 53 are connected, and the exhaust air intake port 52 is used as the inlet of the exhaust gas, and the exhaust air outlet 53 is used as the outlet of the exhaust gas, thereby forming an exhaust air flow path 5 in which the air as the exhaust gas flows. That is, the exhaust gas flows into the exhaust air flow path 5 from the exhaust air intake port 52 and flows out from the exhaust air outlet 53. The exhaust air intake port 52 may be provided with an exhaust dust collection filter for collecting dust of the exhaust gas sucked from the exhaust air intake port 52.

[0058] The air conditioner 1 has a fan for conveying supply air and exhaust air. The fan includes a supply air fan 41 for conveying supply air and an exhaust fan 51 for conveying exhaust air. The supply air fan 41 and the exhaust fan 51 may be, for example, an axial flow fan such as a propeller fan or a Sirocco fan. The supply air fan 41 is arranged near the supply air outlet 43, and is located on the downstream side of the cooling unit 20 in the supply air flow direction in the supply air flow path 4, and serves as a suction fan.

[0059] The exhaust fan 51 is arranged near the exhaust outlet 53, and is located on the downstream side of the sensible heat exchanger 3 in the exhaust flow direction in the exhaust flow path 5, and is used as an intake fan. The air supply fan 41 and the exhaust fan 51 are not limited to these modes, and each may be an ejection fan or an intake fan. When the air supply fan 41 and the exhaust fan 51 are ejection fans, the air supply fan 41 is arranged near the air supply inlet 42, and the exhaust fan 51 is arranged near the exhaust inlet 52.

[0060] The exhaust gas sent by the exhaust fan 51 is sucked from the exhaust suction port 52 and flows into the exhaust path 32 of the sensible heat exchanger 3. Since the exhaust suction port 52 is formed on the door 12, the exhaust gas sucked from the exhaust suction port 52 flows into the exhaust path 32 of the sensible heat exchanger 3 after passing through the door 12.

[0061] The sensible heat exchanger 3 is provided with an air supply path 31 through which the supply air flows and an exhaust path 32 through which the exhaust air flows. That is, the sensible heat exchanger 3 includes the air supply path 31 and the exhaust path 32. As described above, in the air conditioner 1, as air flow paths, the supply air path 4 through which the supply air flows and the exhaust air path 5 through which the exhaust air flows are provided. The supply air path 31 of the sensible heat exchanger 3 constitutes a part of the supply air path 4, and the exhaust air path 32 of the sensible heat exchanger 3 constitutes a part of the exhaust air path 5.

[0062] The air supply path 31 and the exhaust path 32 in the sensible heat exchanger 3 are formed of a plurality of resin plates having a hollow structure, such as plastic corrugated paper, and these plates are arranged in parallel and stacked to form the sensible heat exchanger 3. The sensible heat exchanger 3 reduces the weight of the sensible heat exchanger 3 while improving heat conductivity by reducing the thickness of the resin plate. The hollow structure may also be formed of a metal plate.

[0063] The air supply path 31 and the exhaust path 32 are provided with a plurality of resin plates stacked perpendicularly to each other, and sensible heat exchange between the air supply and the exhaust is performed through these resin plates. The stacking direction of these stacked resin plates is perpendicular to the path directions of the air supply path 31 and the exhaust path 32. That is, in the present embodiment, the path direction of the air supply path 31 is from right to left, and the path direction of the exhaust path 32 is from top to bottom. In contrast, the stacking direction is the front-to-back direction perpendicular to the above-mentioned left-right and up-down directions. In this way, the air supply path 31 and the exhaust path 32 are orthogonal to each other, so that the air supply flowing in the air supply path 31 and the exhaust flowing in the exhaust path 32 form a positive flow.

[0064] The inlet and outlet of the air supply path 31 are respectively formed on two opposite side surfaces of the sensible heat exchanger 3. In the figure of this embodiment, the inlet of the air supply path 31 is located on the right surface of the sensible heat exchanger 3, and the outlet of the air supply path 31 is located on the left surface of the sensible heat exchanger 3.

[0065] The air supply path 31 is formed by stacking a plurality of spaces connected from the inlet of the air supply path 31 to the outlet of the air supply path 31. The inlet of the exhaust path 32 is formed on the upper surface of the sensible heat exchanger 3, and the outlet of the exhaust path 32 is formed on the lower surface. The exhaust path 32 is formed by stacking a plurality of spaces connected from the inlet of the exhaust path 32 to the outlet of the exhaust path 32.

[0066] A box-shaped drain pan 6 having an opening at the top is arranged below the cooling unit 20, i.e., the vaporization filter 2 and the sensible heat exchanger 3. The drain pan 6 receives water supplied from the heat exchange water supply unit 33 described later and passed through the sensible heat exchanger 3. In addition, the drain pan 6 receives water supplied from the filter water supply unit 21 described later and passed through the vaporization filter 2. The drain pan 6 is arranged on the downstream side of the sensible heat exchanger 3 in the flow direction of the exhaust gas, with the opening facing the lower surface of the vaporization filter 2 and the sensible heat exchanger 3. That is, the internal space of the drain pan 6, i.e., the water storage space, forms a part of the exhaust gas flow path 5.

[0067] The exhaust gas sucked from the exhaust suction port 52 by the exhaust fan 51 and passed through the exhaust path 32 of the sensible heat exchanger 3 is blown out from the exhaust blow-out port 53 through the water storage space of the drain pan 6 having a box shape and an opening on the upper surface. When passing through the exhaust path 32 of the sensible heat exchanger 3, the exhaust gas is mixed with the water supplied from the heat exchange water supply unit 33 to the exhaust path 32. That is, in the exhaust path 32 of the sensible heat exchanger 3, the flow direction of the exhaust gas is the same as the flow direction of the water, and the exhaust gas and the water form a parallel flow.

[0068] In this embodiment Figure 1 In the example of , the air supply path 31 through which the air supply flows is arranged in a straight line from the right surface to the left surface of the sensible heat exchanger 3. In the flow direction of the air supply, the vaporization filter 2 is arranged on the downstream side of the outlet of the air supply path 31. The vaporization filter 2 is arranged on the air supply flow path 4 between the sensible heat exchanger 3 and the air supply outlet 43. The first intermediate air supply flow path 44 is located between the sensible heat exchanger 3 and the vaporization filter 2, and the first intermediate air supply flow path 44 constitutes a part of the air supply flow path 4.

[0069] The vaporization filter 2 is configured so that one surface of the vaporization filter 2 is opposite to the left surface of the sensible heat exchanger 3 where the outlet of the air supply path 31 is formed. In this way, the vaporization filter 2 is used as a cooling element. The vaporization filter 2 is formed of, for example, rayon, polyester or non-woven fabric. A filter water supply portion 21 having a nozzle 211 is arranged on the upper part of the vaporization filter 2. The filter water supply portion 21 will be described in detail later. The vaporization filter 2 has water absorption, and the water supplied from the filter water supply portion 21 completely permeates the vaporization filter 2, thereby promoting the vaporization of water. The air supply path 4 from the vaporization filter 2 to the air supply outlet 43 is extended upward from the vaporization filter 2.

[0070] The supply air flowing out of the supply air path 31 of the sensible heat exchanger 3 passes through the vaporization filter 2 and is blown out to the air-conditioned space from the supply air outlet 43. The supply air flowing out of the outlet of the supply air path 31 is cooled in two stages by the exhaust gas through the sensible heat exchanger 3 and by the vaporization filter 2. Therefore, the temperature of the supply air is further reduced compared to the direct vaporization method using only the vaporization filter 2, for example.

[0071] The residual water of the sensible heat exchanger 3 and the residual water of the vaporization filter 2 are received by the drain pan 6 located below the sensible heat exchanger 3 and the vaporization filter 2, and the residual water is recovered by being stored in the water storage space of the drain pan 6. The water recovered in the drain pan 6 is supplied to the vaporization filter 2 and the sensible heat exchanger 3 via the supply water path 7.

[0072] like Figure 1 As shown, a drain pan filter 75, a flow sensor 77, and a water supply pump 76 are arranged in the water supply path 7. By driving the water supply pump 76, the water stored in the drain pan 6 is supplied to the filter water supply part 21 arranged above the vaporization filter 2 and the heat exchange water supply part 33 arranged above the sensible heat exchanger 3 through the water supply pump 76. The water dripping from the nozzle 211 of the filter water supply part 21 is supplied to the vaporization filter 2. The water dripping from the nozzle 331 of the heat exchange water supply part 33 is supplied to the exhaust path 32 of the sensible heat exchanger 3. In this way, a circulation water path is formed by the water supply path 7, the heat exchange water supply part 33, the filter water supply part 21, and the drain pan 6 to circulate water between the vaporization filter 2 and the sensible heat exchanger 3 constituting the cooling unit 20 and the drain pan 6.

[0073] The water supply passage 7 is connected to a bottom hole 611 formed on the bottom surface 61 of the drain pan 6. The water supply passage 7 includes a first water supply passage 71 extending from the bottom to the top along the first side wall 111 of the housing 10, a second water supply passage 72 connected to the heat exchange water supply section 33, a connecting water supply passage 73 connecting the first water supply passage 71 and the second water supply passage 72, and a water supply section connecting passage 74 connecting the heat exchange water supply section 33 and the filter water supply section 21. The heat exchange water supply section 33, the filter water supply section 21, the water supply section connecting passage 74, and the second water supply passage 72 are fixed to the door 12. The first water supply passage 71, the second water supply passage 72, and the water supply section connecting passage 74 are composed of, for example, a resin or metal pipe. The heat exchange water supply section 33, the filter water supply section 21, and the connecting water supply passage 73 fixed to the door 12 will be described in detail later.

[0074] The water supply path 7 has a branch portion 78 branching to a drain path 781. The drain path 781 has the branch portion 78 as a base end, and a drain port having an on-off valve or a stopcock is installed at the head end. The drain path 781 is composed of, for example, a resin pipe. When the air conditioner 1 is normally used, the on-off valve of the drain port arranged at the head end, which is the end of the drain path 781, is in a fully closed state. During maintenance work such as maintenance of the air conditioner 1, the water stored in the drain pan 6 can be discharged from the drain port to the outside of the air conditioner 1 by opening the on-off valve.

[0075] The drain pan 6 and the water tank 8 are connected via a replenishing water path 9. The replenishing water path 9 is composed of, for example, a resin or metal pipe. A water tank pump 91 and a water tank flow sensor 92 are arranged on the replenishing water path 9. One end of the replenishing water path 9 is connected to the lower part of the water tank 8, and the other end of the replenishing water path 9 is connected to a water supply hole 621 formed on the wall surface 62 of the drain pan 6. The water supply hole 621 is formed at a position above the bottom hole 611 connected to the supply water path 7. Above the bottom surface 61 of the drain pan 6, a water level sensor 63 is fixed by a sensor fixing member 64. The water level sensor 63 is fixed at a position deviated from the vertical line of the cross section of the water supply hole 621. In other words, the water level sensor 63 is arranged at a position away from the water supply hole 621 in the up-down direction and the left-right direction.

[0076] Figure 5 1 is a perspective view showing the front of the appearance of the air conditioner 1 in a state where the water tank 8 is removed. A water tank platform 116 for arranging the water tank 8 is formed on the second side wall 112 side of the casing 10. The water tank platform 116 is located at a position protruding forward from the second side wall 112, thereby forming a step by the water tank platform 116 and the second side wall 112. A cylindrical protrusion 117 is formed on the upper surface of the water tank platform 116. In the present embodiment, two protrusions 117 are arranged on the upper surface of the water tank platform 116. A connecting hole connected to the replenishing water channel 9 is formed between the two protrusions 117. When the water tank 8 is arranged on the upper surface of the water tank platform 116 as described above, the protrusion 117 is embedded in the concave protrusion receiving portion 81 formed on the lower surface of the water tank 8.

[0077] A locking mechanism 14 for maintaining the door 12 in a closed state is disposed on the second side wall 112 of the housing 10. The locking mechanism 14 is composed of a locking claw 142, a fitting hole 143 to which the locking claw 142 fits, a spring for applying force to the locking claw 142 in a certain direction, and an operating portion 141 for moving the locking claw 142 in a direction that overcomes the force of the spring. More specifically, the locking claw 142, the spring, and the operating portion 141 of the locking mechanism 14 are disposed on the front wall of the door 12 constituting a part of the second side wall 112, and the fitting hole 143 to which the locking claw 142 fits is disposed on the front wall of the body 11 constituting a part of the second side wall 112. The outer surface of the locking mechanism 14 is configured to be located in the same plane as the second side wall 112, that is, the outer surface of the locking mechanism 14 constitutes a part of the second side wall 112. The operating portion 141 is disposed inside a recess formed on the outer surface of the locking mechanism 14, and is composed of a lever or the like used when the door 12 is opened and closed.

[0078] When the water tank 8 is mounted on the housing 10, the water tank 8 is arranged on the upper surface of the water tank platform 116, and at this time, the back of the water tank 8 is opposite to the second side wall 112 of the housing 10. That is, when the water tank 8 is mounted on the housing 10, the outer surface of the locking mechanism 14 is opposite to the back of the water tank 8. In other words, the locking mechanism 14 is formed at a position overlapping with the water tank 8 in the up-down direction and the left-right direction. As a result, the locking mechanism 14 located on the second side wall 112 is covered by the back of the water tank 8. Therefore, when the water tank 8 is mounted on the housing 10, it is possible to prevent the operator of the air conditioner 1 from operating the operating unit 141 to open the door 12.

[0079] Figure 6 It is a perspective view showing the appearance of the water tank 8 . Figure 7 1 is a side sectional view of the water tank 8. The water tank 8 is made of resin or metal, for example, and is in a rectangular box shape. A protrusion receiving portion 81 corresponding to the protrusion 117 of the water tank platform 116 is formed on the lower surface of the water tank 8. As shown in the present embodiment, when the protrusion 117 is formed in a convex shape, the protrusion receiving portion 81 is formed in a concave shape, so that the protrusion 117 and the protrusion receiving portion 81 fit together.

[0080] On the lower surface of the water tank 8, an outflow cylinder 83 is formed between the two protrusion receiving portions 81. The inner space of the outflow cylinder 83 is used as an outflow hole for water to flow out of the water tank 8. The water in the water tank 8 flows into the replenishment water path 9 from the outflow cylinder 83. A valve body that prevents water from flowing out of the water tank 8 can be arranged at the outflow cylinder 83 when the water tank 8 is removed.

[0081] An inflow hole used when pouring water into the water tank 8 is formed on the upper surface of the water tank 8 .

[0082] Figure 81 is a side sectional view of the air conditioner 1 in a state where the water tank 8 is installed. This side sectional view is a view of the state of the casing 10 observed from the third side wall 113. The water tank 8 and the water supply pump 76 that supplies water from the water tank 8 to the drain pan 6 are arranged at different positions from the sensible heat exchanger 3 and the drain pan 6 in the vertical direction and in the direction perpendicular to the direction from the air supply inlet of the air supply path 31 of the sensible heat exchanger 3 toward the air supply outlet. That is, in a side view based on a plane defined by the path direction of the air supply path 31 of the sensible heat exchanger 3 and the vertical direction, the water tank 8 and the water supply pump 76 located below the water tank 8 are arranged at different positions relative to the sensible heat exchanger 3 and the drain pan 6 arranged vertically.

[0083] Fig. 9 This is an explanatory diagram showing a state in which the upper surface of the cooling unit 20 is exposed by opening the door 12 . Fig.10 It is an explanatory diagram showing a state where the cooling unit 20 is removed. Fig.11 1 is an explanatory diagram showing a water supply unit in a state where the door 12 is closed. The housing 10 has a door 12 that can be opened and closed. That is, the door 12 constitutes a part of the housing 10, and the upper surface of the door 12 constitutes a part of the upper surface of the housing 10. The front wall of the door 12 constitutes a part of the second side wall 112 of the housing 10, and a part of a locking mechanism 14 for fixing the door 12 to the body 11 in a closed state is disposed. By operating the operating portion 141, the locking of the locking mechanism 14 is released, and the door 12 is axially rotated on the support portion 115 disposed on the first side wall 111, and becomes an open state.

[0084] The door 12 is box-shaped, and a filter water supply unit 21 and a heat exchange water supply unit 33 are arranged inside the door 12. The filter water supply unit 21 and the heat exchange water supply unit 33 are fixed inside the box-shaped door 12. Therefore, the position state or posture of the filter water supply unit 21 and the heat exchange water supply unit 33 relative to the cooling unit 20 changes in conjunction with the opening and closing of the door 12. The filter water supply unit 21 and the heat exchange water supply unit 33 are examples of water supply units.

[0085] When the door 12 is closed, the filter water supply unit 21 and the heat exchange water supply unit 33 are in a first posture opposite to the upper surface, which is a surface above the cooling unit 20, in a direction perpendicular to the upper surface. When the door 12 is open, the filter water supply unit 21 and the heat exchange water supply unit 33 are in a second posture arranged at a position away from the upper surface in a plane direction orthogonal to the direction perpendicular to the upper surface of the cooling unit 20. In this way, by fixing the filter water supply unit 21 and the heat exchange water supply unit 33 to the door 12, the filter water supply unit 21 and the heat exchange water supply unit 33 can be moved between the first posture and the second posture in conjunction with the opening and closing of the door 12.

[0086] In the present embodiment, the filter water supply unit 21 and the heat exchange water supply unit 33 are fixed to the door 12, but the present invention is not limited thereto. The filter water supply unit 21 and the heat exchange water supply unit 33 may not be fixed to the door 12, but may be arranged as a middle cover between the door 12 and the body 11. The filter water supply unit 21 and the heat exchange water supply unit 33, which are formed as parts of the middle cover, can be in the first posture and the second posture according to the opening and closing state of the middle cover.

[0087] The filter water supply unit 21 and the heat exchange water supply unit 33 fixed to the door 12 are connected by a water supply unit connection path 74. In the present embodiment, two heat exchange water supply units 33 are provided, and the heat exchange water supply unit 33 and the filter water supply unit 21 located on the downstream side in the flow direction of water in the water supply path 7 are connected by the water supply unit connection path 74. The two heat exchange water supply units 33 are connected by a second water supply path 72, and the second water supply path 72 is connected to one end of the connection water supply path 73 after being bent into an L shape. The other end of the connection water supply path 73 is connected to the first water supply path 71 arranged along the first side wall 111 of the housing 10, more specifically, along the first side wall 1111 of the main body side. As described in detail later, the connection water supply path 73 has flexibility and can alleviate or absorb the stress generated when the door 12 is opened and closed.

[0088] like Fig. 9 As shown, the heat exchange water supply part 33 is composed of a rectangular hollow tube made of resin or metal, for example, and a plurality of nozzles 331 formed with holes 332 are arranged on the surface opposite to the sensible heat exchanger 3, that is, the lower surface. The second water supply path 72 passes through the upper part of the heat exchange water supply part 33 and is connected to the connecting port provided in the upper part of the heat exchange water supply part 33. The water flowing into the second water supply path 72 from the connecting water supply path 73 is supplied to the heat exchange water supply part 33 through the connecting port provided in the upper part of the heat exchange water supply part 33. The water supplied to the heat exchange water supply part 33 drips from the holes 332 of the plurality of nozzles 331 located on the lower surface to the upper surface of the sensible heat exchanger 3. The upper surface of the sensible heat exchanger 3 constitutes a part of the upper surface of the cooling unit 20.

[0089] The water supply part 21 for the filter is composed of a rectangular hollow tube made of resin or metal, for example, and a plurality of nozzles 211 formed with holes 212 are arranged on the surface opposite to the vaporization filter 2, that is, the lower surface. In addition, holes are also provided on the right surface of the water supply part 21 for the filter, that is, the side surface on the side of the water supply part 33 for heat exchange. The water supply part 21 for the filter is located at the same height as the water supply part connection path 74 in the vertical direction, and is connected to the communication port provided on the side surface of the water supply part 21 for the filter. The water flowing into the water supply part connection path 74 from the second water supply path 72 is supplied to the water supply part 21 for the filter through the communication port provided on the side surface of the water supply part 21 for the filter. The water supplied to the water supply part 21 for the filter drips from the holes 212 of the plurality of nozzles 211 located on the lower surface to the upper surface of the vaporization filter 2. The upper surface of the vaporization filter 2 constitutes another part of the upper surface of the cooling unit 20. That is, the upper surface of the sensible heat exchanger 3 and the upper surface of the vaporization filter 2 constitute the upper surface of the cooling unit 20. The upper surface of the cooling unit 20 is an example of one surface of the cooling unit.

[0090] The filter water supply unit 21 and the heat exchange water supply unit 33 are connected in series via the water supply unit connection path 74, and a throttle hole 741 described later may also be formed on the water supply unit connection path 74. Thus, the volume flow rate of the filter water supply unit 21 can be made smaller than the volume flow rate of the heat exchange water supply unit 33. The flow rate adjustment in the filter water supply unit 21 and the heat exchange water supply unit 33 is not limited to the case of using the throttle hole 741 of the water supply unit connection path 74, and the flow rate can also be adjusted by making the aperture of the nozzle 211 of the filter water supply unit 21 smaller than the aperture of the nozzle of the heat exchange water supply unit 33.

[0091] By adopting the connection method as described above, inside the box-shaped door 12, the second water supply path 72, the heat exchange water supply unit 33, the water supply unit connection path 74, and the filter water supply unit 21 are arranged in the above order in the flow direction of the water supply. In the internal space of the box-shaped door 12, an area for arranging the filter water supply unit 21 and an area for arranging the heat exchange water supply unit 33 are separated. The area where the heat exchange water supply unit 33 is arranged constitutes a part of the exhaust flow path 5 by being connected to the exhaust air intake port 52 formed on the upper surface of the door 12. That is, the exhaust gas sucked from the exhaust air intake port 52 flows into the exhaust path 32 of the sensible heat exchanger 3 after passing through the area where the heat exchange water supply unit 33 is arranged inside the door 12. When the heat exchange water supply unit 33 is fixed to the door 12, it can also be held by, for example, a rectangular cylindrical frame. In this case, the inside of the frame for holding the heat exchange water supply unit 33 constitutes a part of the exhaust flow path 5. The water supply connection path 74 connecting the heat exchange water supply part 33 and the filter water supply part 21 is arranged through a through hole formed in the frame.

[0092] Since the area for arranging the water supply unit 21 for the filter is configured separately from the exhaust flow path 5 located inside the door 12, the exhaust gas sucked from the exhaust suction port 52 formed in the door 12 does not flow into the area. That is, when the housing 10 is viewed from above, the exhaust suction port 52 formed in the door 12 is arranged at a position deviated from the water supply unit 21 for the filter and at a position overlapping with the water supply unit 33 for heat exchange.

[0093] The filter water supply unit 21 is fixed to the door 12 by a fixing member 122, and a second sealing member 123 is mounted on the fixing member 122. When the door 12 is closed, the second sealing member 123 contacts the upper end of the columnar rib 221 of the vaporization filter housing 22 to ensure the sealing of the air supply path 4. The vaporization filter housing 22 and the like will be described in detail later.

[0094] The door 12 is provided with a receiving portion 121 for receiving a handle portion 37 of a heat exchange housing 34 described later. The receiving portion 121 is arranged corresponding to the position of the handle portion 37 of the heat exchange housing 34 when the door 12 is closed, and is formed in a concave shape on the inner side of the door 12. When the door 12 is closed, since the handle portion 37 of the heat exchange housing 34 is fitted into the receiving portion 121, the handle portion 37 can be arranged so as not to interfere with the water supply portion 21 for the filter, the water supply portion 33 for heat exchange, and the water supply portion connecting path 74. In this way, the handle portions 37 formed on the air supply inlet side frame 35 and the air supply outlet side frame 36 of the heat exchange housing 34 are respectively located on the outer side of the wall body etc. constituting the exhaust flow path 5 inside the door 12, and the ventilation resistance in the exhaust flow path 5 can be reduced. Regarding the positional relationship between the handle portion 37 and the connecting water supply channel 73 , the connecting water supply channel 73 is disposed offset from the handle portion 37 in a second horizontal direction perpendicular to the vertical direction and extending from the first side wall 111 toward the second side wall 112 .

[0095] The filter water supply unit 21 and the heat exchange water supply unit 33 are fixed to the door 12 that can be opened and closed as described above. By closing the door 12, the filter water supply unit 21 and the heat exchange water supply unit 33 can be located above the vaporization filter 2 and the sensible heat exchanger 3, and can be in a first position where water can drip. Moreover, by opening the door 12, the filter water supply unit 21 and the heat exchange water supply unit 33 can be in a second position where the upper surfaces of the vaporization filter 2 and the sensible heat exchanger 3 are exposed. As described above, the vaporization filter 2 is arranged inside the housing 10 in a state where the vaporization filter 2 is accommodated in the vaporization filter case 22 and the sensible heat exchanger 3 is accommodated in the heat exchange case 34. By opening the door 12, when the air conditioner 1 is viewed from above, the filter water supply unit 21 and the heat exchange water supply unit 33 located above the cooling unit 20 during the operation of the air conditioner 1 move to a position different from the cooling unit 20 when the air conditioner 1 is viewed from above. Thus, the vaporizing filter case 22 and the heat exchange case 34 can be pulled upward and removed from the casing 10 , and maintenance work such as cleaning or replacement of the vaporizing filter 2 and the sensible heat exchanger 3 can be efficiently performed.

[0096] Fig.12 It is an explanatory diagram showing the length relationship between the water supply passage 73 and the door 12 . Fig.13 1 is an explanatory diagram showing the connection structure of the water supply unit and the water supply channel 7. The connection water supply channel 73 for connecting the first water supply channel 71 arranged along the first side wall 111 of the housing 10 and the second water supply channel 72 connected to the heat exchange water supply unit 33 fixed to the door 12 has flexibility, for example, it is composed of a highly flexible resin tube or rubber tube.

[0097] The water supply section 33 for heat exchange and the water supply section 21 for filter are connected by a water supply section connection path 74 provided with a throttling hole 741. A nozzle is provided at the head end of the water supply section 33 for heat exchange, and the vertical line of the cross section of the hole of the nozzle is parallel to the exhaust path 32. Thus, the water outflow direction of the nozzle of the water supply section 33 for heat exchange becomes along the direction of the exhaust path 32 in the water supply section 33 for heat exchange, and is perpendicular to the air supply path 31, that is, orthogonal. A nozzle is provided at the head end of the water supply section 21 for filter, and the vertical line of the cross section of the hole of the nozzle is parallel to the exhaust path 32. Thus, the water outflow direction of the nozzle 211 of the water supply section 21 for filter is perpendicular to the flow direction of the supply air in the vaporization filter 2. In the present embodiment, the flow direction of the exhaust gas in the exhaust path 32 is parallel to the water outflow direction of the water flowing out of each nozzle.

[0098] One end of the connecting water supply path 73 is connected to the first water supply path 71, and the other end of the connecting water supply path 73 is connected to the second water supply path 72. The first connecting portion 731, which is a connecting portion between the first water supply path 71 and the connecting water supply path 73, is arranged at a position closer to the third side wall 113 than the fourth side wall 114. The first connecting portion 731 is composed of, for example, a connecting member such as an L-shaped elbow. The second connecting portion 732, which is a connecting portion between the second water supply path 72 and the connecting water supply path 73, is arranged at a position closer to the fourth side wall 114 than the third side wall 113. The second connecting portion 732 is composed of, for example, a connecting member such as an L-shaped elbow. The connecting water supply path 73 can be arranged along the length direction of the first side wall 111, that is, in the first horizontal direction from the third side wall 113 toward the fourth side wall 114, so that the path length of the connecting water supply path 73 can be made relatively long. Furthermore, the length of the path connecting the water supply path 73 is longer than the length of the door 12 in the first horizontal direction perpendicular to the vertical direction and extending from the third side wall 113 toward the fourth side wall 114 .

[0099] By lengthening the path length of the connecting water supply path 73 as described above, even if the connecting water supply path 73 is twisted due to the opening and closing of the door 12, the deformation amount caused by the twist per unit length can be reduced, and the service life of the connecting water supply path 73 can be increased relative to the number of times the door 12 is opened and closed. In addition, the connecting water supply path 73 can be made into a straight line shape, and the component size can be miniaturized to save space, for example, compared with the case of using a bellows-shaped pipe.

[0100] The connecting water supply path 73 can be held by a retaining portion arranged on the inner surface of the first side wall 111. The retaining portion can be composed of, for example, an L-shaped resin member, and the connecting water supply path 73 is held by supporting it from below. Alternatively, the retaining portion can be composed of, for example, an annular resin member, and the connecting water supply path 73 is held by inserting the connecting water supply path 73 into the ring. The connecting water supply path 73 can be held close to the first side wall 111 by the retaining portion. The retaining portion can be located at a position biased toward the first connecting portion 731 of the first water supply path 71 and the connecting water supply path 73. That is, the length from the retaining portion to the first connecting portion 731 of the first water supply path 71 and the connecting water supply path 73 is shorter than the length from the retaining portion to the second water supply path 72 and the second connecting portion 732 of the connecting water supply path 73. By configuring the retaining portion for holding the connecting water supply path 73 in this way, the bending of the flexible connecting water supply path 73 can be suppressed.

[0101] Fig.141 is an explanatory diagram showing the change in position of the connection water supply path 73 when the door 12 is opened and closed. When the door 12 is closed, the connection water supply path 73 is arranged in a straight line along the inner surface of the first side wall 111. At this time, the connection water supply path 73 is arranged at a position away from the exhaust flow path 5 from the exhaust air intake port 52 formed in the door 12 to the inlet of the exhaust path 32 of the sensible heat exchanger 3. Therefore, it is possible to prevent the connection water supply path 73 from becoming a flow path resistance in the exhaust flow path 5.

[0102] When the door 12 is open, the second water supply path 72 and the second connection portion 732 connected to the water supply path 73 are linked with the rotation of the door 12 and are pulled toward the front of the first side wall 111, that is, the outside of the housing 10. Thus, the connection water supply path 73 is positioned toward the second connection portion 732 of the second water supply path 72 located in front of the first side wall 111, with the portion held by the holding portion arranged on the inner surface of the first side wall 111 as a base point. Thus, when the door 12 is opened, the connection water supply path 73 can be moved to a position that does not overlap with the vaporization filter housing 22 and the heat exchange housing 34 when the housing 10 is viewed from above. Therefore, when the door 12 is opened and the vaporization filter housing 22 and the heat exchange housing 34 are pulled upward to be removed from the housing 10, since the connecting water supply path 73 is not located in the pulling direction of the vaporization filter housing 22 and the heat exchange housing 34, the vaporization filter housing 22 and the heat exchange housing 34 can be prevented from being stuck on the connecting water supply path 73.

[0103] Fig.15 It is a perspective view showing the appearance of the heat exchange case 34 . Fig.16 It is an exploded perspective view of the heat exchange housing 34 . Fig.17 1 is an explanatory diagram showing a state where the heat exchange case 34 is inserted into the housing 10. The heat exchange case 34 includes a supply air inlet side frame 35, a supply air outlet side frame 36, a front wall 341, and a rear wall 342, and accommodates the sensible heat exchanger 3.

[0104] The air supply inlet side frame 35 is arranged on the inlet side of the air supply path 31 of the sensible heat exchanger 3. The air supply outlet side frame 36 is arranged on the outlet side of the air supply path 31 of the sensible heat exchanger 3. The inlet of the air supply path 31 of the sensible heat exchanger 3 is formed at the air supply inlet surface 311. Therefore, the air supply inlet side frame 35 is opposite to the air supply inlet surface 311. The outlet of the air supply path 31 of the sensible heat exchanger 3 is formed at the air supply outlet surface 312. Therefore, the air supply outlet side frame 36 is opposite to the air supply outlet surface 312. The air supply inlet side frame 35 and the air supply outlet side frame 36 are opposite to each other, and the combination of the air supply inlet side frame 35 and the air supply outlet side frame 36 constitutes a first opposite portion.

[0105] The front wall 341 connects the air supply inlet side frame 35 and the air supply outlet side frame 36. The rear wall 342 connects the air supply inlet side frame 35 and the air supply outlet side frame 36. The front wall 341 and the rear wall 342 face each other, and the combination of the front wall 341 and the rear wall 342 constitutes a second facing portion.

[0106] A handle 37 for holding when pulling the heat exchange housing 34 out of the main body is formed on the upper surface of each of the air supply inlet side frame 35 and the air supply outlet side frame 36. The handle 37 of each of the air supply inlet side frame 35 and the air supply outlet side frame 36 is formed into a rectangular frame. The handle 37 of the air supply inlet side frame 35 is arranged to be biased toward the rear wall 342. The handle 37 of the air supply outlet side frame 36 is arranged to be biased toward the front wall 341.

[0107] The air supply inlet side frame 35 is configured to be removable from and mounted to the body of the heat exchange housing 34. A plurality of claw-shaped protrusions 353 are formed on the outer edge 352 of the air supply inlet side frame 35. These protrusions 353 may be formed only on the outer edge of the rear wall 342 and the outer edge of the front wall 341 in the outer edge of the air supply inlet side frame 35. A plurality of recesses 343 cooperating with the claw-shaped protrusions 353 are formed on the front wall 341 and the rear wall 342. The end edges of the front wall 341 and the rear wall 342 formed with the plurality of recesses 343 serve as an anti-reverse insertion shape 351 when the heat exchange housing 34 is inserted and accommodated in the housing 10. Alternatively, a groove portion may be formed on the edge of the body of the heat exchange housing 34 for inserting the air supply inlet side frame 35 from above. The groove portion may be L-shaped in a top view of the heat exchange housing 34 observed from above. The air supply inlet side frame 35 has a peripheral edge portion corresponding to the groove portion, and by aligning the peripheral edge portion of the air supply inlet side frame 35 with the groove portion formed on the edge portion of the body of the heat exchange shell 34, the air supply inlet side frame 35 can be effectively embedded in the body of the heat exchange shell 34. The edge portion formed on the air supply inlet side frame 35 can be used as an anti-reverse insertion shape 351 when the heat exchange shell 34 is inserted into the housing 10.

[0108] That is, since the air supply outlet side frame 36 does not have the same portion as the reverse insertion prevention shape 351 formed on the air supply inlet side frame 35, the shapes of the air supply outlet side frame 36 and the air supply inlet side frame 35 can be made different. A receiving portion corresponding to the reverse insertion prevention shape 351 formed on the air supply inlet side frame 35 is formed on the housing 10, and for example, when the direction of the heat exchange housing 34 is reversed, the heat exchange housing 34 cannot be inserted into the housing 10. Therefore, when performing maintenance operations such as replacement or cleaning of the heat exchange housing 34, it is possible to reliably prevent the operator from inserting the heat exchange housing 34 by mistake.

[0109] In the present embodiment, the anti-insertion reverse shape 351 is formed on the air supply inlet side frame 35 and the air supply outlet side frame 36 which are opposite to each other, but it is not limited thereto. The anti-insertion reverse shape may also be formed on any one of the front wall 341 and the rear wall 342 which are opposite to each other. It is also possible to form a rib protruding outward only on either the front wall 341 or the rear wall 342, for example, in the up-down direction. In the front wall 341 or the rear wall 342, a groove which engages with the rib may be formed in the up-down direction on the inner surface of the housing 10 which is opposite to the wall on which the rib is formed. Since the rib is formed only on one of the front wall 341 or the rear wall 342, when the heat exchange housing 34 is accommodated in the housing 10, it is possible to prevent the heat exchange housing 34 from being inserted into the housing 10 in a state where the front wall 341 and the rear wall 342 are opposite. That is, the rib formed only on one of the front wall 341 or the rear wall 342 can be used as the anti-insertion reverse shape.

[0110] A frame-shaped sealing member 361 is attached to the inner surface of the air supply outlet side frame 36. That is, the sealing member 361 is configured to be sandwiched between the inner surface of the air supply outlet side frame 36 and the outlet surface of the air supply path 31 of the sensible heat exchanger 3. By configuring the sealing member 361 in this way, it is possible to prevent the air supply that has passed through the air supply inlet side frame 35 from bypassing the air supply path 31 of the sensible heat exchanger 3. Moreover, the same sealing member 361 can also be configured at the lower part of the heat exchange shell 34 in a manner located at the lower side of the sensible heat exchanger 3. Thus, it is possible to prevent the exhaust gas from the exhaust suction port 52 from bypassing the exhaust path 32 of the sensible heat exchanger 3. A first flange portion for ensuring the sealing of the first intermediate air supply flow path 44 is formed on the air supply outlet side frame 36. The first flange portion will be described in detail later.

[0111] Fig.18 It is a perspective view showing a state where the handle portion 223 stands upright in the appearance of the vaporization filter case 22 . Fig.19 It is a perspective view showing the appearance of the vaporization filter case 22 in a state where the handle portion 223 is folded down. Fig. 20 2 is an exploded perspective view of the vaporization filter housing 22. The vaporization filter housing 22 is formed of a rectangular frame, for example, made of resin or metal. The vaporization filter 2 is accommodated inside the vaporization filter housing 22 formed of the frame. The vaporization filter 2 has a filter inlet surface 201 forming an inlet for supply air and a filter outlet surface 202 forming an outlet for supply air. Therefore, the first direction from the filter inlet surface 201 toward the filter outlet surface 202 corresponds to the flow direction of the supply air passing through the vaporization filter 2.

[0112] A columnar rib 221 protruding upward is formed on the upper surface of the vaporization filter case 22. The columnar rib 221 is in a rectangular cylindrical shape, and the inner section formed by the columnar rib 221 is used as a flow path when water supplied from the filter water supply unit 21 fixed to the door 12 drips into the vaporization filter 2.

[0113] Wall surfaces 62 protruding from the edges of the upper surface of the vaporization filter housing 22 are provided to cover the outer periphery of the columnar rib 221 in the shape of a rectangular cylinder. A U-shaped handle portion 223 is rotatably mounted on two wall surfaces 62 facing each other in the wall surface 62. The handle portion 223 configured to be rotatable can be in a fallen state between the columnar rib 221 and the wall surface 62, and in a standing state upward from the upper surface of the vaporization filter housing 22. By making the handle portion 223 in the fallen state between the columnar rib 221 and the wall surface 62, the handle portion 223 can be arranged in a position deviated from the internal space of the columnar rib 221, that is, in the flow path of water supplied from the filter water supply unit 21.

[0114] The upper surface of the vaporization filter housing 22 is arranged so that the head end of the upper surface is located outside the vaporization filter 2 in the state where the vaporization filter 2 is accommodated. That is, the upper surface of the vaporization filter housing 22 is extended in parallel with the flow direction of the supply air passing through the vaporization filter 2. The upper surface extended in this way forms the second flange portion 222. The second flange portion 222 is used as a portion to ensure the sealing performance of the first intermediate supply air flow path 44.

[0115] In a state where the vaporization filter 2 is accommodated in the vaporization filter housing 22, a filter frame 224 is arranged opposite to one surface of the vaporization filter 2. In the flow direction of the supply air passing through the vaporization filter 2, the filter frame 224 is arranged on the upstream side of the vaporization filter 2. The filter frame 224 is configured to be removable from and mounted to the main body of the vaporization filter housing 22, and the vaporization filter 2 can be removed from the vaporization filter housing 22 in a state where the filter frame 224 is removed. A plurality of claw-shaped protrusions 226 are formed on the outer edge of the filter frame 224. On the main body of the vaporization filter housing 22, on the peripheral edge where the filter frame 224 is fitted, a plurality of recesses 227 that cooperate with the protrusions 226 are formed. The filter frame 224 can be removed from and mounted to the body of the vaporization filter housing 22 by matching the protrusion 226 of the filter frame 224 with the recess 227 formed on the periphery of the body of the vaporization filter housing 22. Alternatively, a groove for inserting the filter frame 224 from above may be formed on the edge of the body of the vaporization filter housing 22. The filter frame 224 has a peripheral portion corresponding to the groove, and the filter frame 224 is engaged with the body of the vaporization filter housing 22 by matching the peripheral portion of the filter frame 224 with the groove formed on the edge of the body of the vaporization filter housing 22. An annular rib 225 is formed on the outer surface of the filter frame 224 in the entire circumferential direction. The annular rib 225 is used as a portion for ensuring the sealing in the first intermediate air supply path 44.

[0116] Fig.21 1 is an explanatory diagram showing the first intermediate air supply path 44 interposed between the heat exchange housing 34 and the vaporization filter housing 22 . Fig. 22 1 is an explanatory diagram showing a part of the first intermediate air supply path 44 in an enlarged manner. In the front view when the air conditioner 1 is viewed from the second side wall 112 side, the heat exchange housing 34 accommodating the sensible heat exchanger 3 and the vaporization filter housing 22 accommodating the vaporization filter 2 are arranged adjacent to each other. The air supply outlet side frame 36 of the heat exchange housing 34 is arranged opposite to the filter frame 224 of the vaporization filter housing 22. The first intermediate air supply path 44 constituting a part of the air supply path 4 is located between the air supply outlet side frame 36 of the heat exchange housing 34 and the filter frame 224 of the vaporization filter housing 22 which are opposite to each other. The first intermediate air supply path 44 is constituted by, for example, a cylindrical structural member 441, and connects the outlet of the air supply path 31 of the sensible heat exchanger 3 with the inlet of the air supply in the vaporization filter 2.

[0117] The air supply outlet side frame 36 of the heat exchange housing 34 has a first flange portion extending in the same direction as the flow of the air supply in the path direction of the first intermediate air supply passage 44. Thus, the first flange portion is configured to overlap with the first intermediate air supply passage 44 in the air supply direction. The filter frame 224 of the vaporization filter housing 22 has a second flange portion 222 extending in the opposite direction to the flow of the air supply in the path direction of the first intermediate air supply passage 44. Thus, the second flange portion 222 is configured to overlap with the first intermediate air supply passage 44 in the air supply direction. The air supply direction refers to the flow direction of the air supply flowing in the air supply passage 31 of the sensible heat exchanger 3. In other words, the air supply direction is a first direction from the air supply inlet surface 311 of the sensible heat exchanger 3 toward the air supply outlet surface 312. In the present embodiment, the air supply direction is a direction parallel to the left-right direction.

[0118] The upper portion of the structural member 441 constituting the first intermediate air supply passage 44 is U-shaped in cross-sectional view, and has two upper end portions formed upward. Of the two upper end portions, the end surface of the upper end portion located on the heat exchange housing 34 side contacts the lower surface of the first flange portion 362 of the air supply outlet side frame 36 of the heat exchange housing 34. Of the two upper end portions, the end surface of the upper end portion located on the vaporization filter housing 22 side contacts the lower surface of the second flange portion 222 of the filter frame 224 of the vaporization filter housing 22. Furthermore, the outer surface of the upper end portion located on the vaporization filter housing 22 side contacts the annular rib 225 formed on the filter frame 224.

[0119] In this way, the first flange portion of the air supply outlet side frame 36 of the heat exchange housing 34 is in contact with the second flange portion 222 of the filter frame 224 of the vaporization filter housing 22 and the annular rib 225 relative to the first intermediate air supply passage 44, so that the sealing of the first intermediate air supply passage 44 can be ensured. In the present embodiment, the end surface of the upper end portion of the heat exchange housing 34 is in contact with the lower surface of the first flange portion of the air supply outlet side frame 36 of the heat exchange housing 34, but it is not limited to this, and it can also be configured so that a sealing member or the like is sandwiched between the end surface of the upper end portion of the heat exchange housing 34 and the lower surface of the first flange portion. In the present embodiment, the end surface of the upper end portion of the vaporization filter housing 22 is in contact with the lower surface of the second flange portion 222 of the filter frame 224 of the vaporization filter housing 22, but it is not limited to this, and it can also be configured so that a sealing member or the like is sandwiched between the end surface of the upper end portion of the vaporization filter housing 22 and the lower surface of the second flange portion 222. In this embodiment, the outer surface of the upper end portion of the vaporization filter case 22 is in contact with the annular rib 225 formed on the filter frame 224 , but the present invention is not limited thereto, and a sealing member or the like may be sandwiched between the outer surface and the annular rib 225 .

[0120] In the present embodiment, the heat exchange housing 34 accommodating the sensible heat exchanger 3 and the vaporization filter housing 22 accommodating the vaporization filter 2 are described as different housings, but the present invention is not limited thereto. The sensible heat exchanger 3 and the vaporization filter housing 22 may also be accommodated in a common housing as a single housing. In this case, the common housing accommodating the sensible heat exchanger 3 and the vaporization filter housing 22 includes a first intermediate air supply path 44 located between the sensible heat exchanger 3 and the vaporization filter housing 22.

[0121] Fig.23 is a schematic side cross-sectional view of the drain pan 6 located within the housing 10 . Fig.24 1 and 2 are explanatory diagrams showing the positional relationship between the bottom hole 611 and the water supply hole 621 of the drain pan 6 . Fig.25 1 is an explanatory diagram showing the left side of the water level sensor 63 in a state of being mounted by the sensor fixing member 64 . Fig.26 1 is an explanatory diagram showing the right side of the water level sensor 63 in the state of being installed by the sensor fixing member 64. The drain pan 6 is in the shape of a box having an opening, and the opening faces the sensible heat exchanger 3 and the vaporization filter 2, and is arranged below the sensible heat exchanger 3 and the vaporization filter 2. Water dripping from the sensible heat exchanger 3 and the vaporization filter 2 is received by the drain pan 6 and stored in the water storage space which is the inner space of the drain pan 6.

[0122] The drain pan 6 has a bottom surface 61 and a plurality of wall surfaces 62 extending upward from the edge of the bottom surface 61. A bottom hole 611 is formed in the bottom surface 61, and the water supply channel 7 is connected to the bottom hole 611.

[0123] The plurality of wall surfaces 62 include a rear surface located on the first side wall 111 side of the housing, a front surface located on the second side wall 112 side, a right surface located on the third side wall 113 side, and a left surface located on the fourth side wall 114 side. A water supply hole 621 is formed on the wall surface 62 located on the second side wall 112 side covered by the water tank 8, that is, the front surface. The water supply hole 621 is connected to the water tank 8 through the supplementary water path 9. In this way, by locating the water supply hole 621 on the wall surface 62 on the second side wall 112 side covered by the water tank 8, the path length of the supplementary water path 9 connecting the water tank 8 and the drain pan 6 can be shortened.

[0124] The water supply hole 621 formed on the wall surface 62 is located vertically above the bottom hole 611 formed on the bottom surface 61. With such a position configuration, water can be directly supplied from the drain pan 6 to the heat exchange water supply part 33 and the filter water supply part 21 via the supply water path 7, and water can be directly supplied from the water tank 8 to the drain pan 6 via the replenishment water path 9 to replenish water.

[0125] A water level sensor 63, such as a float switch, is disposed on the bottom surface 61 of the drain pan 6. The water level sensor 63 is fixed to the bottom surface 61 of the drain pan 6 by a box-shaped sensor fixing member 64. The water level sensor 63 fixed in this way is located inside the water storage space of the drain pan 6, and outputs a signal related to the water level of the water stored in the drain pan 6, that is, a water level signal.

[0126] The water level sensor 63 is arranged at a position deviated from the perpendicular direction of the radial section of the water supply hole 621 relative to the water supply hole 621 formed on the wall surface 62. That is, the water level sensor 63 is fixed by the sensor fixing member 64 and arranged in the water storage space of the drain pan 6 so as to deviate from the water outflow direction determined by the path direction of the water supply hole 621. As a result, when the water supplied from the water tank 8 flows from the water supply hole 621 into the water storage space of the drain pan 6, it is possible to prevent the inflowing water from splashing onto the water level sensor 63, and the accuracy of the water level sensor 63 can be ensured.

[0127] The box-shaped sensor fixing member 64 has, for example, a flat wall portion 641, and the water level sensor 63 is fixed in a state covered by the wall portion 641. The wall portion 641 covering the water level sensor 63 is located between the water level sensor 63 and the water supply hole 621. Thus, when water supplied from the water tank 8 flows from the water supply hole 621 into the water storage space of the drain pan 6, the wall portion 641 of the sensor fixing member 64 can shield the inflowing water, and the inflowing water can be prevented from splashing onto the water level sensor 63, thereby ensuring the accuracy of the water level sensor 63.

[0128] As described above, the sensible heat exchanger 3 is accommodated in the heat exchange housing 34, the vaporization filter 2 is accommodated in the vaporization filter housing 22, and the first intermediate supply air flow path 44 constituting a part of the supply air flow path 4 is located between the heat exchange housing 34 and the vaporization filter housing 22. In such a positional relationship, the supply air path 31 of the sensible heat exchanger 3, the first intermediate supply air flow path 44, and the supply air passing flow path in the vaporization filter 2 form a linear supply air flow path 4.

[0129] The drain pan 6 is located below the sensible heat exchanger 3, the first intermediate air supply passage 44, and the vaporizing filter 2, and is arranged below the linear air supply passage 4 formed by them. In such an arrangement structure, the water level sensor 63 is located downstream of the sensible heat exchanger 3 in the direction from the air supply inlet of the sensible heat exchanger 3 toward the air supply outlet. That is, in the top view of the air conditioner 1 viewed from above, the water level sensor 63 is arranged differently from the sensible heat exchanger 3 and is arranged on the downstream side of the outlet of the air supply passage 31 of the sensible heat exchanger 3 in the flow direction of the air supply. Moreover, in the direction from the air supply inlet of the vaporizing filter 2 toward the air supply outlet, the water level sensor 63 is arranged at a different position from the vaporizing filter 2. That is, in the top view of the air conditioner 1 viewed from above, the water level sensor 63 is arranged differently from the vaporizing filter 2 and is arranged on the upstream side of the air supply inlet of the vaporizing filter 2 in the flow direction of the air supply.

[0130] Thus, in the direction from the air supply inlet of the sensible heat exchanger 3 toward the air supply outlet, the water level sensor 63 is located downstream of the sensible heat exchanger 3 and upstream of the vaporization filter 2. As described above, the first intermediate air supply path 44 is located between the sensible heat exchanger 3 and the vaporization filter 2, and the water level sensor 63 is arranged directly below the first intermediate air supply path 44. Therefore, since the water level sensor 63 is arranged at a position away from directly below the sensible heat exchanger 3 and the vaporization filter 2, it is possible to suppress water dripping from the sensible heat exchanger 3 and the vaporization filter 2 from directly falling on the water level sensor 63, thereby ensuring the detection accuracy of the water level sensor 63.

[0131] Fig. 27 It is an explanatory diagram showing a mounted state of the drain pan filter 75 . Fig.28 1 is an explanatory diagram showing the installation and removal of the drain pan filter 75. The supply water path 7 is connected to the bottom hole 611 formed on the bottom surface 61 of the drain pan 6. One end of the supply water path 7 connected to the bottom hole 611 is located below the bottom surface 61 of the drain pan 6, and the drain pan filter 75, the water supply pump 76, and the flow sensor 77 connected in the middle of the path of the supply water path 7 can also be arranged below the bottom surface 61 of the drain pan 6.

[0132] The drain pan filter 75 is cylindrical and contains a cylindrical filter body. The drain pan filter 75 can remove pollutants such as dust and impurities contained in the water flowing in the water supply path 7 by capturing the pollutants. Thus, clogging of the filter water supply part 21 and the heat exchange water supply part 33 can be prevented, and contamination of the sensible heat exchanger 3 and the vaporization filter 2 can be suppressed.

[0133] The drain pan filter 75 formed in a cylindrical shape has a large diameter portion for accommodating the filter body and a small diameter portion located downstream of the large diameter portion in the flow direction of the water supply. An annular gasket may also be arranged in the small diameter portion, and the gasket is used to suppress the dust and the like captured by the filter body from flowing out into the water supply channel 7. The inner diameter (d1) of the large diameter portion is larger than the inner diameter (d2) of the small diameter portion, that is, d1>d2, and the path length (l1) of the large diameter portion is longer than the path length (l2) of the small diameter portion, that is, l1>l2. By adopting such a structure, the size and surface area of ​​the filter body of the drain pan filter 75 can be made relatively large, and the replacement frequency of the drain pan filter 75 can be reduced.

[0134] The drain pan filter 75 is configured to be removable from and mounted on the front wall of the water tank deck 116 parallel to the second side wall 112. More specifically, a hole for the drain pan filter 75 is formed in the front wall of the water tank deck 116, and the drain pan filter 75 is inserted into the hole and arranged in the middle of the path of the water supply channel 7. A cross-shaped handle portion may be formed on the end surface of the cylindrical drain pan filter 75, for example, and a cover covering the handle portion may be installed. With the drain pan filter 75 configured in this way, the drain pan filter 75 can be efficiently mounted and removed. The outer surface of the front wall of the water tank deck 116 constitutes one surface of the housing 10.

[0135] As described above, not only the drain pan filter 75 but also the water tank 8 and the drain passage 781 are arranged on the second side wall 112 side. Therefore, the operator who performs maintenance work on the air conditioner 1 can load and unload the water tank 8, load and unload the drain pan filter 75, and operate the opening and closing valve or the stopcock of the drain passage 781 from the second side wall 112 side, so that the maintenance work can be performed efficiently. In addition, by removing the water tank 8, the locking mechanism 14 is exposed, and the operating part 141 of the locking mechanism 14 can also be operated from the second side wall 112 side. Therefore, a series of maintenance work including opening and closing of the door 12 and removal and installation of the vaporization filter housing 22 and the heat exchange housing 34 can be performed from the second side wall 112 side. In this way, the parts required for maintenance work are concentrated on the second side wall 112 side, and the second side wall 112 can be used as a service surface faced by the operator during maintenance work.

[0136] Fig.29 1 is a block diagram showing each functional part in the air conditioner 1. The air conditioner 1 has a substrate 100 including a control unit 101. A microcomputer including a memory and an MPU is mounted on the substrate 100, and the microcomputer is used as the control unit 101 for driving control of the water supply pump 76 and the water tank pump 91. The program executed by the control unit 101 is stored in the memory.

[0137] The substrate 100 may be disposed, for example, on the outer surface of a flow path wall forming the exhaust flow path 5, and may be thermally connected to the flow path wall to be cooled by the exhaust gas flowing in the exhaust flow path 5. The air supply fan 41, the exhaust fan 51, the water level sensor 63, the water supply pump 76, the flow sensor 77, the water tank pump 91, and the water tank flow sensor 92 as electrical components of the air conditioner 1 are connected to the control unit 101 provided on the substrate 100 via a communication line in a manner capable of communicating.

[0138] The water level sensor 63 is, for example, a float sensor, and outputs a water level signal, which is a signal related to the detection result of the water level of the water stored in the drain pan 6, to the control unit 101. The flow sensor 77 and the water tank flow sensor 92 are, for example, an impeller type or a clamp type flow sensor 77, which outputs a first flow signal, which is a signal related to the detection result of the flow rate of water flowing in the supply water path 7, to the control unit 101. The water tank flow sensor 92 outputs a second flow signal, which is a signal related to the detection result of the flow rate of water flowing in the replenishment water path 9, to the control unit 101.

[0139] The control unit 101 determines whether the water level of the drain pan 6 is below a specified value based on the signal obtained from the water level sensor 63, that is, the water level signal. If it is determined to be below the specified value, the control unit 101 drives the water tank pump 91 to replenish water from the water tank 8 to the drain pan 6. The control unit 101 can also perform fault detection or determine whether the water tank 8 is empty based on the first flow rate signal and the second flow rate signal from the flow sensor 77 and the water tank flow rate sensor 92.

[0140] In the present embodiment, a sensible heat exchanger 3 is used as a heat exchanger, but the heat exchanger may also be a total heat exchanger. In addition, as the door 12, a door 12 that can be opened and closed by rotating relative to the main body 11 through a support portion 115 composed of a hinge or the like is used, but it is not limited to this. The door 12 may also slide in the front-back or left-right direction. Alternatively, the door 12 may also be composed of a cover that can be mounted on and removed from the main body 11. In this case, there are claws on both sides of the cover that can be inserted into the holes on the side of the main body 11. When the claws are pulled out, the cover floats, thereby becoming a state in which the sensible heat exchanger 3 or the like can be replaced. In this way, in a state in which the claws are detached, the cover is connected to the main body only by connecting the water supply path 73. In this way, in a case where the housing 10 has a main body 11 and a cover connected to the main body 11, the upper surface of one surface of the cooling unit 20 arranged inside the main body 11 is covered by the cover. A water supply portion for supplying water to the upper surface, a water supply path 7 arranged inside the body 11, and a flexible connecting water supply path 73 connecting the water supply portion and the water supply path 7 are arranged between the cover and the upper surface of the cooling unit 20. Since the connecting water supply path 73 is flexible, maintenance work such as replacement of the cooling unit 20 can be performed without completely removing the cover.

[0141] In the present embodiment, the air conditioner 1 has a cooling unit 20 and a water supply unit for supplying water to one surface of the cooling unit 20. The cooling unit 20 includes an air supply path 31 and an exhaust path 32. The water supply unit moves between a first posture and a second posture, the first posture being a posture opposite to the one surface in the vertical direction of the one surface, and the second posture being a posture arranged at a position away from the one surface in the plane direction orthogonal to the vertical direction. Therefore, when the air conditioner 1 is running, the water supply unit can supply water to the cooling unit 20 in the first posture. When performing maintenance work on the air conditioner 1, the water supply unit moves from the first posture to the second posture. As a result, one surface of the cooling unit 20 is exposed in the field of vision from above, so that maintenance work such as replacement or cleaning of the cooling unit 20 can be effectively performed. The water supply unit can also supply water only to at least a portion of one surface of the cooling unit. In addition, one surface of the cooling unit can also be a side surface of the cooling unit.

[0142] In the present embodiment, the air conditioner 1 has a housing 10 that accommodates a cooling unit 20. The housing 10 has a door 12 that is located above the cooling unit 20 and can be opened and closed, and a water supply unit is fixed to the door 12. The water supply unit is configured to move between a first posture and a second posture in conjunction with the opening and closing of the door 12. Specifically, the water supply unit assumes a first posture when the door 12 is closed, and assumes a second posture when the door 12 is open. In this way, by changing the posture of the water supply unit in conjunction with the opening and closing of the door 12, maintenance operations such as replacement or cleaning of the cooling unit 20 can be effectively performed.

[0143] In the present embodiment, a support portion 115 such as a hinge is installed on the first side wall 111 of the housing 10, and the door 12 is supported by the support portion 115. Therefore, by pivoting the support portion 115, the door 12 can be smoothly opened and closed. In addition, the air conditioner 1 has a supply water path 7 connected to the water supply part. The supply water path 7 includes: a first water supply path 71 arranged along the first side wall 111; a second water supply path 72 fixed to the door 12 and connected to the water supply part; and a connecting water supply path 73 connecting the first water supply path 71 and the second water supply path 72. The connecting water supply path 73 is flexible. Although the connecting water supply path 73 is deformed or stressed as the door 12 is opened and closed, the connection water supply path 73 can be improved in terms of tolerance to the number of times the door 12 is opened and closed by being able to respond to the deformation within the range of elastic deformation due to its flexibility.

[0144] In the present embodiment, the housing 10 has a second side wall 112, a third side wall 113, and a fourth side wall 114 that are opposite to the first side wall 111. The third side wall 113 connects the first side wall 111 and the second side wall 112. The fourth side wall 114 connects the first side wall 111 and the second side wall 112, and is opposite to the third side wall 113. The first connecting portion 731 that connects the first water supply path 71 and the connecting water supply path 73 is arranged at a position closer to the third side wall 113 than the fourth side wall 114. The second connecting portion 732 that connects the second water supply path 72 and the connecting water supply path 73 is arranged at a position closer to the fourth side wall 114 than the third side wall 113. By adopting such a configuration structure, the path length of the connecting water supply path 73 can be made longer, and the deformation amount per unit length can be reduced in the deformation caused by the opening and closing of the door 12. As a result, the tolerance of the connecting water supply path 73 to the number of times the door 12 is opened and closed can be improved.

[0145] In the present embodiment, the length of the water supply path 73 in the first horizontal direction perpendicular to the vertical direction and from the third side wall 113 toward the fourth side wall 114 is longer than the length of the door 12 in the first horizontal direction. Thus, the path length of the water supply path 73 can be made longer, and the deformation per unit length can be reduced in the deformation caused by the opening and closing of the door 12. Thus, the tolerance of the water supply path 73 to the number of times the door 12 is opened and closed can be improved.

[0146] In this embodiment, the connection water supply channel 73 is offset relative to the cooling unit 20 in the second horizontal direction orthogonal to the vertical direction and the first horizontal direction. Thus, the connection water supply channel 73 can be arranged at a position where the flow path when supplying water from the water supply unit to the cooling unit 20 is offset.

[0147] In the present embodiment, the cooling unit 20 includes: a sensible heat exchanger 3 including an air supply path 31 and an exhaust path 32; and a vaporization filter 2 connected to the air supply path 31. The water supply portion includes a heat exchange water supply portion 33 for supplying water to the exhaust path 32 of the sensible heat exchanger 3 and a filter water supply portion 21 for supplying water to the vaporization filter 2. Therefore, water can be supplied from the heat exchange water supply portion 33 and the filter water supply portion 21 to the sensible heat exchanger 3 and the vaporization filter 2, respectively. The supply water path 7 includes a water supply portion connection path 74 connecting the heat exchange water supply portion 33 and the filter water supply portion 21, and the heat exchange water supply portion 33 is connected to the second water supply path 72. Therefore, in the flow direction of the supplied water, the heat exchange water supply portion 33 can be arranged on the upstream side of the filter water supply portion 21, and water can be preferentially supplied to the heat exchange water supply portion 33.

[0148] In the present embodiment, a throttle hole 741 is provided in the water supply section connection path 74, for example, and the inner diameter of at least a portion of the water supply section connection path 74 is configured to be smaller than the inner diameter of any portion of the second water supply path 72. That is, the flow resistance of the water supply section connection path 74 is greater than the flow resistance of the second water supply path 72. Thus, the amount of water supplied to the filter water supply section 21 located on the downstream side of the water supply section connection path 74 in the flow direction of the water supply can be made less than the amount of water supplied to the heat exchange water supply section 33, and water supply to the heat exchange water supply section 33 can be performed preferentially.

[0149] In the present embodiment, the air conditioner 1 has a water tank 8 that is detachably arranged on the housing 10 along the outer surface of the second side wall 112. A locking mechanism 14 is arranged on the housing 10 for fixing the door 12 to the body 11 when the door 12 is closed. The outer surface of the locking mechanism 14 constitutes a part of the outer surface of the second side wall 112. The water tank 8 is opposite to the outer surface of the locking mechanism 14 when it is installed on the housing 10. Thus, when the water tank 8 is installed on the housing 10, the locking mechanism 14 is covered by the back of the water tank 8. Therefore, it is possible to physically restrict the operation of the operating unit 141 so that it is possible to operate only when the water tank 8 is in a removed state. Thus, when the water tank 8 is installed on the air conditioner 1, the door 12 can be prevented from being opened.

[0150] In this embodiment, the water supply unit has a nozzle on the lower surface opposite to the cooling unit 20. Specifically, the heat exchange water supply unit 33 has a nozzle 331 on the lower surface opposite to the upper surface of the sensible heat exchanger 3. The vertical line of the cross section of the hole of the nozzle 331 is parallel to the exhaust path 32 in the sensible heat exchanger 3. That is, the water outlet direction of the nozzle is along the direction of the exhaust path 32, and water can be effectively supplied to the exhaust path 32.

[0151] In the present embodiment, the sensible heat exchanger 3 is arranged inside the housing 10 in a state of being accommodated in the heat exchange housing 34 formed with the handle portion 37. An accommodating portion 121 for inserting the handle portion 37 of the heat exchange housing 34 is formed on the inner surface of the door 12 constituting a part of the housing 10. Therefore, when the door 12 is closed, the handle portion 37 of the heat exchange housing 34 is inserted into the accommodating portion 121. Thus, it is possible to prevent the handle portion 37 of the heat exchange housing 34 from interfering with the heat exchange water supply portion 33 and the filter water supply portion 21 fixed to the housing 10.

[0152] In the present embodiment, the connection water supply passage 73 is offset relative to the handle portion 37 in a second horizontal direction that is orthogonal to the vertical direction and that extends from the first side wall 111 toward the second side wall 112 of the housing 10. Thus, interference between the connection water supply passage 73 and the handle portion 37 of the heat exchange housing 34 can be avoided, and when the heat exchange housing 34 is removed from the housing 10, the connection water supply passage 73 can be prevented from being scratched or damaged.

[0153] In the present embodiment, the air conditioner 1 has a casing 10, a cooling unit 20, a water supply unit, a water supply path 7 disposed inside a main body 11, and a flexible connecting water supply path 73. The casing 10 has a main body 11 and a door 12 connected to the main body 11. The cooling unit 20 is disposed inside the main body 11 and has a surface covered by the door 12. The water supply unit is disposed between the door 12 and the surface of the cooling unit 20, and supplies water to the surface of the cooling unit 20. The connecting water supply path 73 connects the water supply unit and the water supply path 7. When performing a replacement operation of the cooling unit 20, the surface of the cooling unit 20 is exposed by moving the door 12. Although the connecting water supply path 73 is subjected to deformation or stress by moving the door 12, due to its flexibility, it can cope with the deformation within the range of elastic deformation, and the tolerance of the connecting water supply path 73 to the number of times the door 12 is opened and closed can be improved.

[0154] In the present embodiment, the air conditioner 1 includes a housing 10, a sensible heat exchanger 3 disposed inside the housing 10 and including an air supply path 31 and an exhaust path 32, and a heat exchange housing 34 that can be mounted and removed relative to the housing 10 in a state where the sensible heat exchanger 3 is accommodated. The sensible heat exchanger 3 includes an air supply inlet surface 311 forming an inlet of the air supply path 31 and an air supply outlet surface 312 forming an outlet of the air supply path 31. The heat exchange housing 34 includes a first portion and a second portion. The first portion includes a first wall 341 parallel to the air supply path 31 and the exhaust path 32, and an air supply inlet side frame 35 disposed opposite to the air supply inlet surface 311 and connected to the first wall 341. The second portion includes a second wall 342 opposed to the first wall 341 and connected to the air supply inlet side frame 35, and an air supply outlet side frame 36 disposed opposite to the air supply outlet surface 312 and connected to the first wall 341 and the second wall 342. Since the first part has a different shape from the second part, the first part and the second part are formed into a left-right asymmetric shape. Therefore, when the heat exchange shell 34 is inserted into the housing 10, it is possible to prevent the heat exchange shell 34 from being inserted in a state in which the heat exchange shell 34 is facing in the opposite direction. Alternatively, the heat exchange shell 34 may also have a relative portion composed of parts that are opposite to each other, and one part and another part that constitute the relative portion have different shapes. In this way, since the relative portion of the heat exchange shell 34 is formed such that one part and another part have different shapes, that is, a left-right asymmetric shape, when the heat exchange shell 34 is inserted into the housing 10, it is possible to prevent the heat exchange shell 34 from being inserted in a state in which the heat exchange shell 34 is facing in the opposite direction.

[0155] In the present embodiment, the air supply inlet side frame 35 has a shape different from that of the air supply outlet side frame 36. In this way, since the air supply inlet side frame 35 and the air supply outlet side frame 36 that form the opposing portion of the heat exchange shell 34 are formed in different shapes, when the heat exchange shell 34 is inserted into the housing 10, it is possible to prevent the heat exchange shell 34 from being inserted in a state in which the heat exchange shell 34 is facing in the opposite direction.

[0156] In the present embodiment, the first wall 341 has a shape different from that of the second wall 342. In this way, since the first wall 341 and the second wall 342 forming the opposing portion of the heat exchange housing 34 are formed in different shapes, when the heat exchange housing 34 is inserted into the housing 10, it is possible to prevent the heat exchange housing 34 from being inserted in a state in which the orientation is reversed.

[0157] In the present embodiment, the air conditioner 1 has a sealing member 361 that is in close contact with the inner surface of the air supply outlet side frame 36 and the outlet surface of the air supply path 31 of the sensible heat exchanger 3. That is, the sealing member 361 is arranged between the outlet surface of the air supply path 31 and the inner surface of the air supply outlet side frame 36. By arranging the sealing member 361 in this way, the sealing property in the air supply flow path 4 can be ensured, and non-cooling wind, that is, air that has not passed through the sensible heat exchanger 3, can be prevented from being mixed into the air supply. In addition, it is possible to suppress the air supply from bypassing the air supply path 31 of the sensible heat exchanger 3 without passing through it.

[0158] In the present embodiment, the sealing member 361 is fixed to the air supply outlet side frame 36. Thus, the sealing property in the air supply flow path 4 can be further improved, and the sealing property can be improved compared with the case where the sealing member 361 is formed integrally with the sensible heat exchanger 3. In addition, the air supply outlet side frame 36 can also be formed integrally with the heat exchange shell 34. In this way, by integrally fixing the air supply outlet side frame 36 and the sealing member 361 to the main body of the heat exchange shell 34, the sealing property of the outlet surface side of the air supply path 31 of the sensible heat exchanger 3 in the air supply flow path 4 can be improved.

[0159] In the present embodiment, an air supply path 4 which is a part of the air supply path 31 of the sensible heat exchanger 3 is arranged inside the housing 10. The air supply path 4 includes a first intermediate air supply path 44 which is located at a downstream position than the air supply outlet surface 312 where the outlet of the air supply path 31 of the sensible heat exchanger 3 is formed, in the first direction from the air supply inlet surface toward the air supply outlet surface, i.e., the air supply direction. The air supply outlet side frame 36 has a first flange portion 362 protruding downstream in the first direction. The first flange portion 362 is arranged in a manner overlapping with the first intermediate air supply path 44 in the first direction. Therefore, the sealing property in the first intermediate air supply path 44 can be improved. Thus, it is possible to prevent non-cooling air, i.e., air that has not passed through the sensible heat exchanger 3, from mixing into the air supply to the air supply path 4 located downstream of the sensible heat exchanger 3.

[0160] In the present embodiment, the air supply inlet side frame 35 is installed in a removable manner relative to the heat exchange shell 34. That is, the air supply outlet side frame 36 is integrally formed with the body of the heat exchange shell 34, whereas the air supply inlet side frame 35 and the body of the heat exchange shell 34 are configured to be separable. In this way, by installing the air supply inlet side frame 35 in a removable manner relative to the body of the heat exchange shell 34, the sensible heat exchanger 3 accommodated in the heat exchange shell 34 can be removed from the side where the air supply inlet side frame 35 is installed in a state where the air supply inlet side frame 35 is removed. Therefore, the sensible heat exchanger 3 accommodated in the heat exchange shell 34 can be replaced effectively. In addition, when the sensible heat exchanger 3 is installed and removed from the heat exchange shell 34, the damage of the sealing member 361 can be suppressed.

[0161] In the present embodiment, an anti-reverse insertion shape 351 is formed on the first wall 341 and the second wall 342 of the heat exchange housing 34. Thus, the first wall 341 and the second wall 342 have different shapes. The anti-reverse insertion shape 351 is formed by the end edges of the first wall 341 and the second wall 342, which are located on the side of the air supply inlet side frame 35. By forming the anti-reverse insertion shape 351 in this way, the first wall 341 and the second wall 342 can be different shapes, and when the heat exchange housing 34 is inserted into the housing 10, it is possible to prevent the heat exchange housing 34 from being inserted in a state in which the heat exchange housing 34 is facing in the opposite direction. In the first wall 341 and the second wall 342, a recess 343 is formed at the end edge forming the anti-reverse insertion shape 351, and the recess 343 cooperates with the protrusion 353 formed on the outer edge 352 of the air supply inlet side frame 35, thereby, the anti-reverse insertion shape 351 can be formed on the side of the air supply inlet side frame 35.

[0162] In the present embodiment, the cooling unit 20 has a vaporization filter 2. The air conditioner 1 has a vaporization filter housing 22 that can be mounted on and removed from the housing 10 in a state where the vaporization filter 2 is accommodated. Therefore, by removing the vaporization filter housing 22 from the housing 10, maintenance work such as replacement of the vaporization filter 2 can be effectively performed. The air conditioner 1 also has a filter water supply portion 21 that supplies water to the vaporization filter 2. In addition, the vaporization filter housing 22 has a columnar rib 221 extending from its upper surface toward the filter water supply portion 21. The water supplied from the filter water supply portion 21 is supplied to the vaporization filter 2 through the space surrounded by the columnar rib 221. In this way, by using the space surrounded by the columnar rib 221 as a flow path for the water supplied from the filter water supply portion 21, the water can be reliably guided to the vaporization filter 2 located in the vaporization filter housing 22, and water can be effectively supplied to the vaporization filter 2.

[0163] In the present embodiment, the housing 10 has a door 12 that can be opened and closed, and the water supply part 21 for the filter is fixed to the door 12 by a fixing member 122. A second sealing member 123 is arranged on the fixing member 122. When the door 12 is in a closed state, the second sealing member 123 contacts the upper end of the columnar rib 221. Although the internal space of the columnar rib 221, which becomes the flow path of water from the water supply part 21 for the filter to the vaporization filter 2, is connected to the flow path of the air supply in the vaporization filter 2, when the air conditioner 1 is running and the door 12 is in a closed state, by making the upper end of the columnar rib 221 contact with the second sealing member 123 located on the inner surface of the door 12, it is possible to suppress the non-cooling wind from mixing into the air supply passing through the vaporization filter 2. In addition, it is possible to suppress the air supply from leaking from the top of the columnar rib 221 to the outside of the air supply flow path 4.

[0164] In the present embodiment, the vaporization filter housing 22 has a second flange portion 222 protruding in the first direction, i.e., the upstream direction of the air supply direction. More specifically, the filter frame 224 of the vaporization filter housing 22 has a second flange portion 222 protruding in the direction opposite to the flow direction of the air supply in the path direction of the first intermediate air supply path 44. Since the second flange portion 222 of the vaporization filter housing 22 is arranged in a manner overlapping with the first intermediate air supply path 44 in the first direction, the sealing performance of the first intermediate air supply path 44 can be improved, and the mixing of non-cooling air into the air supply path 4 located on the upstream side of the vaporization filter 2 can be suppressed.

[0165] In the present embodiment, the vaporization filter case 22 that accommodates the vaporization filter 2 has a rotatable handle 223. By using the rotatable handle 223, when the vaporization filter case 22 is removed from the housing 10, the handle 223 can be rotated so as to be gripped, and the vaporization filter case 22 can be easily removed from the housing 10 by gripping the rotated handle 223. That is, the rotatable handle 223 can improve the ease of removal of the vaporization filter case 22 without increasing the size of the housing 10 of the air conditioner 1.

[0166] In the present embodiment, the handle 223 of the vaporization filter case 22 is configured to be rotatable, and when the door 12 is in the closed state, it is located outside the wall constituting the columnar rib 221. Thus, when the internal space of the columnar rib 221 formed on the vaporization filter case 22 becomes a flow path of water from the filter water supply unit 21 to the vaporization filter 2, the handle 223 can be arranged at a position away from the flow path.

[0167] In the present embodiment, the heat exchange housing 34 has a handle portion 37. More specifically, the air supply inlet side frame 35 and the air supply outlet side frame 36 of the heat exchange housing 34 each have a handle portion 37. By holding the handle portions 37 formed on the air supply inlet side frame 35 and the air supply outlet side frame 36, respectively, the heat exchange housing 34 can be easily removed from the housing 10. The exhaust air intake port 52 and the exhaust flow path 5 for inhaling and exhausting are formed on the door 12 constituting a part of the housing 10. Since the handle portion 37 of the heat exchange housing 34 is located outside the exhaust flow path 5 formed on the door 12, the ventilation resistance in the exhaust flow path 5 can be reduced.

[0168] In the present embodiment, the air conditioner 1 includes a cooling unit 20, a water supply unit for supplying water to the cooling unit 20, a drain pan 6, a supply water path 7, a water tank 8 for storing water, and a replenishing water path 9. The cooling unit 20 includes a vaporization filter 2 and a sensible heat exchanger 3. The water supply unit includes a filter water supply unit 21 for supplying water to the vaporization filter 2 and a heat exchange water supply unit 33 for supplying water to the sensible heat exchanger 3. The drain pan 6 receives water dripping from the cooling unit 20. The supply water path 7 connects the drain pan 6 and the water supply unit. The replenishing water path 9 connects the water tank 8 and the drain pan 6. The water supply unit is connected to a bottom hole 611 formed on the bottom surface 61 of the drain pan 6 via the supply water path 7. The water tank 8 is connected to a water supply hole 621 formed on the wall surface 62 of the drain pan 6 via the replenishing water path 9. The water supply hole 621 formed on the wall surface 62 is located above the bottom hole 611 formed on the bottom surface 61 in the vertical direction. Therefore, the structure of the drain pan 6 can temporarily store the water supplied through the water supply hole 621 in the drain pan 6, and directly supply the stored water to the filter water supply unit 21 and the heat exchange water supply unit 33 through the bottom hole 611. As a result, for example, compared with the case where an additional water storage tank is arranged on the water supply channel 7 between the drain pan 6 and the water supply unit, water leakage from the drain pan 6 can be suppressed. In addition, it is not necessary to arrange an additional water storage tank on the water supply channel 7 between the drain pan 6 and the water supply unit, so that the product size can be miniaturized and the product weight can be reduced.

[0169] In the present embodiment, the air conditioner 1 has a water level sensor 63. The water level sensor 63 is arranged in the water storage space, i.e., the internal space, of the box-shaped drain pan 6. The water level sensor 63 is arranged to deviate from a line perpendicular to the cross section of the water supply hole 621 formed on the side surface of the drain pan 6, i.e., to be arranged at a position offset with respect to the ejection direction, i.e., the water outflow direction, of the water supplied from the water supply hole 621. Therefore, it is possible to avoid the water supplied from the water supply hole 621 from splashing onto the water level sensor 63, thereby suppressing erroneous detection of the water level sensor 63 and ensuring the detection accuracy of the water level.

[0170] In the present embodiment, the water level sensor 63 is fixed to the bottom plate of the drain pan 6 by the sensor fixing member 64. The sensor fixing member 64 is formed in a box shape, for example, and has a wall portion 641. The wall portion 641 is located between the water level sensor 63 and the water supply hole 621. Therefore, even if a part of the water supplied from the water supply hole 621 is ejected in the direction of the water level sensor 63, it will be shielded by the wall portion 641 of the sensor fixing member 64. Therefore, it is possible to avoid the water supplied from the water supply hole 621 from splashing onto the water level sensor 63, thereby suppressing the erroneous detection of the water level sensor 63 and ensuring the detection accuracy of the water level. In addition, compared with the case where a baffle plate, for example, is configured separately from the sensor fixing member 64 in order to exert the same function as the wall portion 641 of such a structure, the number of components can be reduced, the product cost can be reduced, the product weight can be reduced, and the product size can be miniaturized by saving space.

[0171] In the present embodiment, the cooling unit 20 includes a sensible heat exchanger 3 having an air supply path 31 and an exhaust path 32. The sensible heat exchanger 3 has an air supply inlet surface 311 forming an inlet of the air supply path 31 and an air supply outlet surface 312 forming an outlet of the air supply path 31. The water level sensor 63 is fixed to the bottom plate of the drain pan 6, and the drain pan 6 is located below the sensible heat exchanger 3. Therefore, the water level sensor 63 is also located below the sensible heat exchanger 3. Moreover, in the first direction from the air supply inlet surface 311 of the sensible heat exchanger 3 toward the air supply outlet surface 312, the water level sensor 63 is located at a position on the downstream side of the sensible heat exchanger 3. That is, the water level sensor 63 is arranged at a position away from directly below the sensible heat exchanger 3. The position directly below the sensible heat exchanger 3 is a position directly below the outlet of the exhaust path 32 of the sensible heat exchanger 3, and unvaporized water drips from the outlet of the exhaust path 32. Since the water level sensor 63 is located on the downstream side of the sensible heat exchanger 3 in the direction from the inlet to the outlet of the air supply path 31, water dripping from the outlet of the exhaust path 32 does not fall on the water level sensor 63, but is received by the drain pan 6. By configuring the water level sensor 63 in this way, it is possible to prevent water dripping from the outlet of the exhaust path 32 of the sensible heat exchanger 3 from falling on the water level sensor 63, suppress erroneous detection of the water level sensor 63, and ensure the detection accuracy of the water level.

[0172] In the present embodiment, the cooling unit 20 includes a vaporization filter 2. The vaporization filter 2 has a filter inlet surface 201 forming an inlet of the supply air and a filter outlet surface 202 forming an outlet of the supply air. The water level sensor 63 is fixed to the bottom plate of the drain pan 6, and the drain pan 6 is located below the vaporization filter 2. Therefore, the water level sensor 63 is also located below the vaporization filter 2. Moreover, the water level sensor 63 is arranged at a position different from that of the vaporization filter 2 in the flow direction of the supply air passing through the vaporization filter 2. That is, the water level sensor 63 is arranged at a position away from the vaporization filter 2 directly below. The position directly below the vaporization filter 2 corresponds to the position where the water that is not vaporized in the vaporization filter 2 drops. Since the water level sensor 63 is arranged at a position different from that of the vaporization filter 2 in the flow direction of the supply air passing through the vaporization filter 2, the water that drops from the bottom of the vaporization filter 2 does not fall on the water level sensor 63, but is received by the drain pan 6. By disposing the water level sensor 63 in this way, it is possible to prevent water dripping from the vaporization filter 2 from falling onto the water level sensor 63, thereby suppressing erroneous detection by the water level sensor 63 and ensuring the detection accuracy of the water level.

[0173] In the present embodiment, the water level sensor 63 is fixed to the bottom plate of the drain pan 6, and the drain pan 6 is located below the vaporization filter 2 and the sensible heat exchanger 3. Therefore, the water level sensor 63 is also located below the vaporization filter 2 and the sensible heat exchanger 3. Moreover, the water level sensor 63 is located between the sensible heat exchanger 3 and the vaporization filter 2 arranged along the flow direction of the supply air. That is, the water level sensor 63 is arranged at a position away from the sensible heat exchanger 3 and the vaporization filter 2. Therefore, it is possible to prevent water dripping from the sensible heat exchanger 3 and the vaporization filter 2, respectively, from falling on the water level sensor 63, it is possible to suppress erroneous detection of the water level sensor 63, and it is possible to ensure the detection accuracy of the water level.

[0174] In the present embodiment, a water supply pump 76 and a drain pan filter 75 are arranged on the water supply path 7. The water stored in the drain pan 6 is drawn by the water supply pump 76. The drain pan filter 75 is arranged between the water supply pump 76 and the bottom hole 611 of the drain pan 6 in the water supply path 7. Therefore, the water stored in the drain pan 6 passes through the drain pan filter 75 before passing through the water supply pump 76. Even if the water stored in the drain pan 6 contains pollutants such as dust or impurities, the dust can be collected by the drain pan filter 75. That is, the pollutants in the water recirculated through the water supply path 7 and the drain pan 6, that is, the water recycled by circulation can be removed. As a result, clogging can be suppressed in the water supply pump 76, the filter water supply unit 21, and the heat exchange water supply unit 33, and pollutants can be suppressed in the sensible heat exchanger 3 and the vaporization filter 2, so that the replacement frequency of the sensible heat exchanger 3 and the vaporization filter 2 can be reduced.

[0175] In the present embodiment, the drain pan filter 75 and the water tank 8 are both arranged on the same surface of the housing 10, that is, on the second side wall 112 side in the present embodiment, and are installed in a manner that they can be removed from the surface of the housing 10. Therefore, the operator of the air conditioner 1 or the operator who performs maintenance work can perform the removal work of the drain pan filter 75 and the water tank 8 from the same surface side such as the second side wall 112 of the housing 10, and can perform the work efficiently.

[0176] In the present embodiment, a water tank pump 91 is disposed in the replenishing water path 9. The water tank 8 and the water tank pump 91 are disposed at different positions from the sensible heat exchanger 3 and the drain pan 6 in the vertical direction and in the direction perpendicular to the flow direction of the supply air passing through the sensible heat exchanger 3. Thus, the water tank 8 and the water supply pump 76 can be arranged vertically and disposed beside the sensible heat exchanger 3 and the drain pan 6 in the horizontal direction, that is, in the front in the present embodiment, and the overall height of the housing 10 of the air conditioner 1, that is, the product height, can be reduced.

[0177] In this embodiment, the housing 10 has a protrusion 117 on its outer wall. The water tank 8 has a hole-shaped protrusion receiving portion 81 corresponding to the protrusion 117. The protrusion receiving portion 81 of the water tank 8 fits into the protrusion 117 of the housing 10. Thus, the water tank 8 can be effectively positioned when it is mounted on the housing 10. It is also possible to form a cylindrical protrusion on the lower surface of the water tank, and form a hole-shaped protrusion receiving portion corresponding to the protrusion on the housing.

[0178] (Second Embodiment)

[0179] Hereinafter, an air conditioner 1 according to a second embodiment will be described with reference to the drawings. Fig.30 This is an explanatory diagram showing a state in which the upper surface of the cooling unit 20 is exposed by opening the door 12 of the second embodiment. Fig.31 1 is an explanatory diagram showing a state where the cooling unit 20 is removed. Inside the door 12 of the air conditioner 1 of the second embodiment, the filter water supply part 21 and the heat exchange water supply part 33 are arranged in the same manner as in the first embodiment. In addition, a water receiving part for receiving water dripping from the water supply part is arranged inside the door 12, and the water receiving part includes a heat exchange water receiving part 131 and a vaporization filter water receiving part 132.

[0180] The heat exchange water receiving portion 131 is shovel-shaped and is configured to protrude vertically from the inner surface of the door 12. The heat exchange water receiving portion 131 is configured between the heat exchange water supply portion 33 and the support portion 115, that is, the base end of the heat exchange water receiving portion 131 is located between the heat exchange water supply portion 33 and the support portion 115 on the inner surface of the door 12.

[0181] The head end of the shovel-shaped heat exchange water receiving portion 131 is located at a position farther from the inner surface of the door 12 than the nozzle 331 of the heat exchange water supply portion 33. The protruding direction of the heat exchange water receiving portion 131 is parallel to the direction of the nozzle 331 of the heat exchange water supply portion 33. When the door 12 is closed, the protruding direction of the heat exchange water receiving portion 131 and the direction of the nozzle 331 of the heat exchange water supply portion 33 are downward. When the door 12 is open, the protruding direction of the heat exchange water receiving portion 131 and the direction of the nozzle 331 of the heat exchange water supply portion 33 are forward.

[0182] The heat exchange water receiving part 131 has a rectangular flat plate portion extending in the direction of separation of the two heat exchange water supply parts 33 and side walls formed at both ends of the length direction of the flat plate portion, and a shovel shape is formed by the flat plate portion and the two side walls located at both ends of the length direction. The length direction of the flat plate portion of the heat exchange water receiving part 131 is arranged to be perpendicular to the length direction of the heat exchange water supply part 33 in the rectangular box shape.

[0183] When the door 12 is open, the heat exchange water supply unit 33 is in a posture with its longitudinal direction in the up-and-down direction, and a height difference is generated in the plurality of nozzles 331 arranged in the longitudinal direction. Thus, it is assumed that water attached to or remaining in these nozzles 331 drips from the nozzles 331 located below. In this way, even if the water in the nozzles 331 drips due to opening the door 12, the water can be received by the shovel-shaped heat exchange water receiving unit 131. In addition, condensation water or dripping water may also be attached to the surface of the nozzles 331 of the heat exchange water supply unit 33, and it can be assumed that the water attached to the surface of the nozzles 331 is shaken off when the door 12 is opened. In this way, even if the water attached to the surface of the nozzles 331 is shaken off due to opening the door 12, the water can be received by the shovel-shaped heat exchange water receiving unit 131.

[0184] Fig.32 is a schematic side cross-sectional view of the heat exchange housing 34 located within the housing 10 . Fig.33 This is an explanatory diagram showing a part of the heat exchange casing 34 in an enlarged manner. Fig.34 It is a plan view of the heat exchange casing 34 in a state where the sensible heat exchanger 3 is accommodated. Fig.35 3 is a top view of the heat exchange housing 34 in a state where the sensible heat exchanger 3 is removed. An inclined surface is formed on the first wall 341 of the heat exchange housing 34, which is inclined from the upper end of the first wall 341 toward the bottom wall 383 of the heat exchange housing 34, and the inclined surface constitutes the heat exchange inclined surface 381. That is, the heat exchange inclined surface 381 is formed on the first wall 341, which is a side surface opposite to the first side wall 111 of the housing 10 where the support portion 115 is arranged when the heat exchange housing 34 is arranged in the housing 10.

[0185] The inclined surface portion 381 for heat exchange is inclined in such a manner that, among the first wall 341 of the heat exchange housing 34 and the side surface of the sensible heat exchanger 3 opposite to the first wall 341, the surface distance between the inclined surface portion 381 for heat exchange of the first wall 341 and the side surface of the sensible heat exchanger 3 decreases from the top to the bottom. Therefore, the upper end of the inclined surface portion 381 for heat exchange is wide, and the upper end of the inclined surface portion 381 for heat exchange and the side surface of the sensible heat exchanger 3 form an insertion portion into which the head end of the water receiving portion 131 for heat exchange is inserted.

[0186] The length of the heat exchange inclined surface portion 381 in the left-right direction is greater than the length of the heat exchange water receiving portion 131 in the left-right direction. In addition, the heat exchange water receiving portion 131 is arranged at a position overlapping with the heat exchange shell 34 in the left-right direction. Specifically, the left end of the heat exchange water receiving portion 131 is located on the right side of the left end of the heat exchange shell 34, and the right end of the heat exchange water receiving portion 131 is located on the left side of the right end of the heat exchange shell 34. Therefore, in a state where the door 12 is closed, the head end of the heat exchange water receiving portion 131 is located between the heat exchange inclined surface portion 381 of the first wall 341 and the side surface of the sensible heat exchanger 3, that is, inserted into the insertion portion formed by the heat exchange inclined surface portion 381 and the side surface of the sensible heat exchanger 3 opposite to the heat exchange inclined surface portion 381. Thus, by closing the door 12, the water received by the heat exchange water receiving portion 131 can flow from the heat exchange inclined surface portion 381 into the space between the heat exchange inclined surface portion 381 and the sensible heat exchanger 3 side, and be guided to the bottom wall 383 located below the heat exchange housing 34. In this way, the water received by the heat exchange water receiving portion 131 flows between the inner surface of the first wall 341 formed with the heat exchange inclined surface portion 381 and the side surface of the sensible heat exchanger 3 opposite to the first wall 341, and the heat exchange drainage path 382 is formed by the inner surface of the first wall 341 and the side surface of the sensible heat exchanger 3. That is, the heat exchange drainage path 382 includes the heat exchange inclined surface portion 381 and the bottom wall hole 384 formed on the bottom wall 383 of the heat exchange housing 34.

[0187] The heat exchange housing 34 has a frame-shaped bottom wall 383 connected to the air supply inlet side frame 35, the air supply outlet side frame 36, the first wall 341 and the second wall 342. A triangular hole, for example, is formed on the bottom wall 383, and the triangular hole corresponds to the bottom wall hole 384. One or more bottom wall holes 384 are formed at the four corners or corners of the bottom wall 383 in the shape of a rectangular frame, which is a connection part with any one of the first wall 341, the second wall, the air supply inlet side frame 35 and the air supply outlet side frame 36. The bottom wall holes 384 are formed, for example, at two corners at both ends of the connection part with the air supply inlet side frame 35. By forming the bottom wall holes 384 near the connection part with the air supply inlet side frame 35 on the bottom wall 383 of the heat exchange housing 34, it is possible to prevent water flowing onto the bottom wall 383 from flowing out from the air supply suction port located near the air supply inlet side frame 35.

[0188] A drain pan 6 is disposed below the heat exchange housing 34, and a heat exchange fitting member 39 is disposed between the heat exchange housing 34 and the drain pan 6. When the heat exchange housing 34 is disposed in the housing 10, the heat exchange fitting member 39 fits with the heat exchange housing 34. The heat exchange fitting member 39 can also be used as a structural member constituting the inner wall of the housing 10. A heat exchange communicating hole 391 corresponding to the bottom wall hole 384 is formed in the heat exchange fitting member 39, and the heat exchange communicating hole 391 constitutes a part of the heat exchange drain path 382. Since the heat exchange communicating hole 391 constituting a part of the heat exchange drain path 382 is connected to the drain pan 6, the water flowing in the heat exchange drain path 382 eventually flows into the drain pan 6 through the heat exchange communicating hole 391. Thus, by closing the door 12, the water received by the heat exchange water receiving part 131 can be recovered into the drain pan 6 via the heat exchange drainage passage 382, ​​and water dripping from the nozzle 331 of the heat exchange water supply part 33 when opening and closing the door 12 can be prevented from flowing out to the outside of the shell 10.

[0189] The inner diameter of the heat exchange connecting hole 391 is, for example, 3 mm (Φ3), and the hole area of ​​the bottom wall hole 384 is also set to the same value as the heat exchange connecting hole 391. In this way, by setting the hole areas of the heat exchange connecting hole 391 and the bottom wall hole 384 to relatively small values, the ventilation resistance in the heat exchange drainage path 382 can be increased, and the bypass without passing through the sensible heat exchanger 3 can be fully suppressed.

[0190] Fig.361 is a schematic side sectional view of the vaporization filter housing 22 located in the housing 10. The vaporization filter water receiving portion 132 is shovel-shaped and is arranged to protrude vertically from the inner surface of the door 12. The vaporization filter water receiving portion 132 is arranged between the filter water supply portion 21 and the support portion 115, that is, the base end of the vaporization filter water receiving portion 132 is located between the filter water supply portion 21 and the support portion 115 on the inner surface of the door 12.

[0191] The tip end of the shovel-shaped vaporization filter water receiving portion 132 is located farther from the inner surface of the door 12 than the nozzle 211 of the filter water supply portion 21. The protruding direction of the vaporization filter water receiving portion 132 is parallel to the direction of the nozzle 211 of the filter water supply portion 21. When the door 12 is closed, the protruding direction of the vaporization filter water receiving portion 132 and the direction of the nozzle 211 of the filter water supply portion 21 are downward. When the door 12 is open, the protruding direction of the vaporization filter water receiving portion 132 and the direction of the nozzle 211 of the filter water supply portion 21 are forward.

[0192] The water receiving part 132 for the vaporization filter has a rectangular flat plate part and side walls formed at both ends of the length direction of the flat plate part, and the flat plate part and the two side walls at both ends of the length direction form a shovel shape. The length direction of the flat plate part of the water receiving part 132 for the vaporization filter is arranged in a manner perpendicular to the length direction of the rectangular box-shaped filter water supply part 21.

[0193] When the door 12 is open, the water receiving portion 132 for the vaporization filter is in a posture with the longitudinal direction in the up-down direction, and a height difference is generated in the plurality of nozzles 211 arranged in the longitudinal direction. Thus, it is assumed that water attached to or remaining in these nozzles 211 drips from the nozzles 211 located below. In this way, even if the water in the nozzles 211 drips due to the opening of the door 12, the water can be received by the shovel-shaped water receiving portion 132 for the vaporization filter. In addition, condensation water or dripping water may be attached to the surface of the nozzles 211 of the water receiving portion 132 for the vaporization filter, and the water attached to the surface of the nozzles 211 may be shaken off when the door 12 is opened. In this way, even if the water attached to the surface of the nozzles 211 is shaken off by opening the door 12, the water can be received by the shovel-shaped water receiving portion 132 for the vaporization filter.

[0194] On the upper surface of the vaporization filter case 22, a columnar rib 221 protruding upward is formed similarly to the first embodiment, and a drip rib 231 is formed protruding upward. The drip rib 231 is rectangular similarly to the columnar rib 221, and is formed at a position closer to the outer edge than the columnar rib 221. When the vaporization filter case 22 is arranged in the housing 10, the drip rib 231 is located between the columnar rib 221 and the support portion 115. On the upper surface of the vaporization filter case 22, a hole is formed inside the drip rib 231, which corresponds to the drip hole 232.

[0195] A drain pan 6 is disposed below the vaporization filter case 22, and a vaporization filter fitting member 24 is disposed between the vaporization filter case 22 and the drain pan 6. When the vaporization filter case 22 is disposed in the housing 10, the vaporization filter case 22 fits into the vaporization filter fitting member 24. The vaporization filter fitting member 24 may also be used as a structural member constituting the inner wall of the housing 10.

[0196] The vaporization filter fitting member 24 is formed with an inclined surface that is inclined from the upper side to the lower side, and the inclined surface constitutes the vaporization filter inclined surface portion 241. The vaporization filter inclined surface portion 241 is formed on the first side wall 111 side of the housing 10 where the support portion 115 is arranged, similarly to the heat exchange inclined surface portion 381. Therefore, the vaporization filter inclined surface portion 241 is arranged between the drip rib 231 and the support portion 115.

[0197] The inclined surface portion 241 for the vaporization filter is inclined in such a manner that the distance between the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22, which faces the inner surface on which the inclined surface portion 241 for the vaporization filter is formed, decreases from the upper side to the lower side, in the inner surface of the vaporization filter fitting member 24. Therefore, the upper end of the inclined surface portion 241 for the vaporization filter is wide, and an insertion portion into which the head end portion of the vaporization filter water receiving portion 132 is inserted is formed by the upper end of the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22.

[0198] The length of the inclined surface portion 241 for the vaporization filter in the left-right direction is greater than the length of the water receiving portion 132 for the vaporization filter in the left-right direction. In addition, the water receiving portion 132 for the vaporization filter is arranged at a position overlapping with the inclined surface portion 241 for the vaporization filter in the left-right direction. In detail, the left end of the water receiving portion 132 for the vaporization filter is located on the right side of the left end of the inclined surface portion 241 for the vaporization filter, and the right end of the water receiving portion 132 for the vaporization filter is located on the left side of the right end of the inclined surface portion 241 for the vaporization filter. Therefore, when the door 12 is closed, the head end of the water receiving portion 132 for the vaporization filter is located between the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22, that is, inserted into the insertion portion formed by the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22 opposite to the inclined surface portion 241 for the vaporization filter. Thus, by closing door 12 , water received by vaporization filter water receiving portion 132 can flow from vaporization filter inclined surface portion 241 into between vaporization filter inclined surface portion 241 and the side surface of vaporization filter case 22 and be guided to the bottom portion below vaporization filter fitting member 24 .

[0199] A hole is formed at the bottom of the vaporization filter fitting member 24, which corresponds to the vaporization filter communication hole 243. The vaporization filter communication hole 243 communicates with the drain pan 6 located below the vaporization filter housing 22. In this way, water received by the vaporization filter water receiving portion 132 flows between the inner surface of the vaporization filter fitting member 24 formed with the vaporization filter inclined surface portion 241 and the side surface of the vaporization filter housing 22 opposite to the inner surface, and an outer drainage path 242 is formed by the inner surface of the vaporization filter fitting member 24 and the side surface of the vaporization filter housing 22. The outer drainage path 242 includes the vaporization filter inclined surface portion 241 and the vaporization filter communication hole 243.

[0200] The drip hole 232 formed inside the drip rib 231 on the upper surface of the vaporization filter case 22 communicates with the inside of the vaporization filter case 22. The vaporization filter 2 is accommodated inside the vaporization filter case 22. Therefore, the water flowing into the inside of the vaporization filter case 22 through the drip hole 232 flows into the drain pan 6 through the inner drain path 233 formed by the gap between the vaporization filter 2 and the vaporization filter case 22. Alternatively, the water flowing into the inside of the vaporization filter case 22 through the drip hole 232 permeates the vaporization filter 2.

[0201] When the door 12 is opened, even if water drips from the nozzle 211 of the water supply unit 21 for the filter, the water can be received by the water receiving unit 132 for the vaporization filter. On this basis, by closing the door 12, the water received by the water receiving unit 132 for the vaporization filter can be recovered into the drain pan 6 via the outer drainage path 242 including the inclined surface portion 241 for the vaporization filter and the communication hole 243 for the vaporization filter. In addition, by arranging the drip rib 231 adjacent to the inclined surface portion 241 for the vaporization filter, the water that has passed over the inclined surface portion 241 for the vaporization filter can be contained inside the drip rib 231 and can flow into the inner drainage path 233, that is, the inside of the vaporization filter case 22, through the drip hole 232 formed inside the drip rib 231. Thus, the water dripping from the nozzle 211 of the water supply unit 21 for the filter when the door 12 is opened and closed can be prevented from flowing out to the outside of the housing 10.

[0202] The inner diameter of the communicating hole 243 for the vaporization filter is, for example, 3 mm (Φ3), and the hole area of ​​the communicating hole 243 for the vaporization filter is set to a sufficiently small value relative to the cross-sectional area of ​​the path through which the supply air flows in the vaporization filter 2. Thus, by setting the hole area of ​​the communicating hole 243 for the vaporization filter to a relatively small value, the ventilation resistance of the outer drainage path 242 can be increased, and the bypass without passing through the vaporization filter 2 can be fully suppressed.

[0203] In the present embodiment, the heat exchange water receiving portion 131 and the vaporization filter water receiving portion 132 are formed in a shovel shape with a head end, but are not limited thereto. The heat exchange water receiving portion 131 and the vaporization filter water receiving portion 132 may be, for example, a flexible member such as a sheet, one end of which is coupled to the inner side of the door 12 and the other end is coupled to the inner side of the housing 10. The heat exchange water receiving portion 131 and the vaporization filter water receiving portion 132, which are made of a soft sheet or the like, are flexible and can cope with deformation when the door 12 is opened and closed.

[0204] Fig.37 39 is a schematic side sectional view showing the return portion 392. The heat exchange fitting member 39 to which the heat exchange housing 34 is fitted is provided with the return portion 392 for suppressing water from flowing out of the heat exchange fitting member 39, and the return portion 392 is used as a water recovery structure.

[0205] The return portion 392 is formed on a side plate of the heat exchange fitting member 39 facing the air inlet side frame 35 of the heat exchange housing 34 and protrudes outward from the side plate. The return portion 392 is located near the lower frame of the air inlet side frame 35 below the side plate.

[0206] The return portion 392 is formed to cover a portion of the supply air flow path through which the supply air passes in the heat exchange fitting member 39 from the bottom to the top. Thus, it is possible to suppress the water accumulated in the heat exchange housing 34 or the heat exchange fitting member 39 from flowing out to the outside of the heat exchange fitting member 39. Therefore, for example, even if the air conditioner 1 is placed on a moving body such as a vehicle and the air conditioner 1 is tilted as the vehicle moves, it is possible to suppress the water from flowing out to the outside of the casing 10.

[0207] In the present embodiment, the air conditioner 1 has a housing 10 that accommodates a cooling unit 20. The housing 10 has a door 12 that can be opened and closed and a support portion 115 that supports the door 12 on a first side wall 111 of the housing 10. The door 12 to which the water supply portion is fixed has a water receiving portion. The water receiving portion is arranged between the water supply portion and the support portion 115. Therefore, when the door 12 is opened, even if water drips from the water supply portion, the dripping water can be received by the water receiving portion. Thus, it is possible to prevent the water dripping from the water supply portion from flowing out to the outside of the housing 10.

[0208] In the present embodiment, the air conditioner 1 has a vaporization filter housing 22 and a vaporization filter fitting member 24. The housing 10 has the vaporization filter fitting member 24, which fits with the vaporization filter housing 22 when the vaporization filter housing 22 is accommodated in the housing 10. The water receiving portion includes a vaporization filter water receiving portion 132. The vaporization filter water receiving portion 132 is arranged to overlap with the vaporization filter fitting member 24 in a first horizontal direction perpendicular to the vertical direction and parallel to the first wall 341, that is, in the left-right direction. An outer drainage path 242 through which water from the vaporization filter water receiving portion 132 flows is formed by the inner wall of the vaporization filter fitting member 24 and the outer wall of the vaporization filter housing 22 opposite to the inner wall. Therefore, the water received by the vaporization filter water receiving portion 132 can flow into the outer drainage path 242. In addition, a vaporization filter communication hole 243 forming a part of the outer drainage path 242 is formed at the bottom of the vaporization filter fitting member 24. Therefore, the water flowing into the outer drainage passage 242 from the vaporization filter water receiving portion 132 can be discharged from the vaporization filter communication hole 243 .

[0209] In the present embodiment, an inclined surface portion 241 for a vaporization filter is formed on the inner wall of the vaporization filter fitting member 24, which is inclined from the upper side to the lower side. In the first horizontal direction, the length of the inclined surface portion 241 for the vaporization filter is greater than the length of the vaporization filter water receiving portion 132. Therefore, by closing the door 12, the head end portion of the vaporization filter water receiving portion 132 can be located between the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22, and inserted into the insertion portion formed by the inclined surface portion 241 for the vaporization filter and the side surface of the vaporization filter housing 22 opposite to the inclined surface portion 241 for the vaporization filter. As a result, the water received by the vaporization filter water receiving portion 132 can be effectively guided to the bottom portion located below the vaporization filter fitting member 24 via the insertion portion.

[0210] In the present embodiment, the air conditioner 1 has a heat exchange housing 34 for accommodating the sensible heat exchanger 3. The heat exchange housing 34 has a first wall 341 that is opposite to the first side wall 111 of the housing 10 when the housing 10 is accommodated therein. The first wall 341 is provided with a heat exchange inclined surface 381 that is inclined from the upper end toward the bottom wall 383. The heat exchange inclined surface 381 is disposed below the support portion 115 that supports the door 12 in a rotatable manner. Although there is a concern that water may drip from the nozzle 331 of the heat exchange water supply portion 33 disposed inside the door 12 when the door 12 is opened, the water dripping from the nozzle 331 of the heat exchange water supply portion 33 flows from the inclined surface formed on the first wall 341 of the heat exchange housing 34, that is, along the heat exchange inclined surface 381 from the upper side of the first wall 341 to the bottom wall 383 located below. Therefore, even when water drips from the nozzle 331 of the heat exchange water supply unit 33 , it is possible to suppress the water from flowing out to the outside of the casing 10 of the air conditioner 1 .

[0211] In the present embodiment, the heat exchange housing 34 has a frame-shaped bottom wall 383 connected to the air supply inlet side frame 35, the air supply outlet side frame 36, the first wall 341 and the second wall 342, and a hole is formed on the bottom wall 383. The hole of the bottom wall 383 is formed near the connection position with any one of the first wall 341, the second wall, the air supply inlet side frame 35 and the air supply outlet side frame 36. That is, the hole of the bottom wall 383 is formed at least one at the four corners or corners of the bottom wall 383 of the heat exchange housing 34 in a rectangular frame shape. The bottom wall hole 384 is an example of a hole of the bottom wall 383. The hole of the bottom wall 383 is, for example, aligned with the corner of the bottom wall 383 and formed into a triangular shape. In addition, the hole of the bottom wall 383 can also be formed at two corners at both ends of the connection position with the air supply inlet side frame 35, for example. The hole of the bottom wall 383 is not limited to the hole formed on the bottom wall 383 itself, and may be formed by, for example, a combination of a notch portion formed in an arc shape or the like on the outer edge of the bottom wall 383 and an air supply inlet side frame 35 connected to the bottom wall 383. Assuming that water drips from the nozzle 331 when the door 12 is opened, the water dripping from the nozzle 331 will accumulate on the bottom wall 383 of the heat exchange housing 34. Even in the case where the water dripping from the nozzle 331 accumulates on the bottom wall 383 of the heat exchange housing 34, the water can be discharged to the outside of the heat exchange housing 34 through the hole formed in the bottom wall 383. That is, since the drain pan 6 is arranged below the heat exchange housing 34, the water dripping from the nozzle 331 of the heat exchange water supply unit 33 can be discharged to the drain pan 6 through the bottom wall hole 384.

[0212] In the present embodiment, a heat exchange inclined surface portion 381 is formed on the inner surface of the first wall 341 of the heat exchange housing 34, which is inclined from the upper end toward the bottom wall 383. The water receiving portion includes a heat exchange water receiving portion 131. In the first horizontal direction, the heat exchange water receiving portion 131 is arranged at a position overlapping with the vaporization filter fitting member 24 in the first horizontal direction. In the first horizontal direction, the length of the heat exchange inclined surface portion 381 is greater than the length of the heat exchange water receiving portion 131. Therefore, by closing the door 12, the head end of the heat exchange water receiving portion 131 can be located between the heat exchange inclined surface portion 381 of the first wall 341 and the side surface of the sensible heat exchanger 3, and inserted into the insertion portion formed by the heat exchange inclined surface portion 381 and the side surface of the sensible heat exchanger 3 opposite to the heat exchange inclined surface portion 381. As a result, the water received by the heat exchange water receiving portion 131 can be effectively guided to the bottom wall 383 located below the heat exchange housing 34 through the insertion portion.

[0213] In the present embodiment, the air conditioner 1 has a heat exchange housing 34 for accommodating the sensible heat exchanger 3. The heat exchange housing 34 has a first wall 341 that is opposite to the first side wall 111 of the housing 10 when accommodated in the housing 10. A heat exchange drainage path 382 through which water from the heat exchange drainage portion 131 flows is formed by the inner surface of the first wall 341 and the side surface of the sensible heat exchanger 3 that is opposite to the first wall 341. Therefore, the water received by the heat exchange water receiving portion 131 can flow into the heat exchange drainage path 382. In addition, since a hole (bottom wall hole 384) that forms a part of the heat exchange drainage path 382 is formed on the bottom wall 383 of the heat exchange housing 34, the water that flows into the heat exchange drainage path 382 from the water receiving portion can be discharged from the bottom wall hole 384.

[0214] In the present embodiment, the housing 10 has a heat exchange fitting member 39 that is fitted with the heat exchange housing 34 when the heat exchange housing 34 is accommodated in the housing 10. A return portion 392 is formed on the heat exchange fitting member 39 for suppressing the water from the heat exchange water receiving portion 131 from flowing out to the outside of the heat exchange fitting member 39. Thus, it is possible to suppress the water accumulated in the heat exchange housing 34 or the heat exchange fitting member 39 from flowing out to the outside of the heat exchange fitting member 39. In addition, the return portion 392 is formed on the side plate of the heat exchange fitting member 39 that is opposite to the air supply inlet side frame body 35 of the heat exchange housing 34 in the first horizontal direction. More specifically, the return portion 392 protrudes from the side plate of the heat exchange fitting member 39 toward the upstream of the air supply direction. Thus, it is possible to effectively prevent the water accumulated in the heat exchange housing 34 or the heat exchange fitting member 39 from flowing out to the outside of the housing 10 from the air supply suction port 42.
