Summary of the Invention

Problems to be Solved by the Invention

[0004] Condensed water may be generated on the plate surface of the substrate described in Patent Document 1 by the refrigerant flowing through the refrigerant passage in the substrate. In that case, there is a risk that the condensed water flows from the plate surface through the connection pipe to the valve, causing a failure in the drive unit such as the motor of the valve.

[0005] An object of the present disclosure is to provide an air conditioner capable of suppressing a failure of the drive unit of the valve due to condensed water.

Means for Solving the Problems

[0006] (1) The air conditioner of the present disclosure includes a refrigerant flow path unit having a refrigerant flow path formed therein, and a first valve having a first drive unit a first connecting pipe connecting the refrigerant flow path unit and the first valve; The refrigerant flow path unit is installed with one of its surfaces along the vertical direction. The first drive unit is disposed above the first connecting pipe.

[0007] In the air conditioner configured as described above, since the first drive unit of the first valve is disposed above the first connecting pipe, even if the dew condensation water generated on one surface of the refrigerant flow path unit flows along the first connecting pipe to the first valve, it is possible to suppress the dew condensation water from flowing to the first drive unit. As a result, it is possible to suppress the failure of the first drive unit of the first valve due to dew condensation water.

[0008] (2) The air conditioner further includes a second valve having a second drive unit, and a second connecting pipe connecting the refrigerant flow path unit and the second valve. The second drive unit is preferably disposed above the second connecting pipe. With such a configuration, since the second drive unit of the second valve is disposed above the second connecting pipe, even if the dew condensation water generated on one surface of the refrigerant flow path unit flows along the second connecting pipe to the second valve, it is possible to suppress the dew condensation water from flowing to the second drive unit. As a result, it is possible to suppress the failure of the second drive unit of the second valve due to dew condensation water.

[0009] (3) The first drive unit and the second drive unit are preferably arranged so as to avoid overlapping positions in a plan view. With such a configuration, it is possible to suppress the dew condensation water generated in one of the first valve and the second valve from dripping onto the drive unit of the other valve. As a result, it is possible to suppress the failure of the first drive unit and the second drive unit due to dew condensation water.

[0010] (4) The second valve is preferably disposed below the first valve. With such a configuration, even if the second valve is disposed below the first valve, by arranging the first drive unit and the second drive unit so as to avoid overlapping positions with each other in plan view, it is possible to suppress the condensed water generated in the first valve from dripping onto the second drive unit of the second valve.

[0011] (5) The second valve is disposed below the first connection pipe, the second drive unit is preferably arranged avoiding a position below the lowermost part of the first connection pipe. With such a configuration, even if the condensed water generated in the first valve flows into the first connection pipe, it is possible to suppress the condensed water from dripping from the lowermost part of the first connection pipe onto the second drive unit. As a result, it is possible to suppress the second drive unit from malfunctioning due to the condensed water.

[0012] (6) The second drive unit is preferably arranged avoiding a position overlapping the first connection pipe in plan view. With such a configuration, even if the condensed water generated on one surface of the refrigerant flow path unit flows into the first connection pipe, it is possible to suppress the condensed water from dripping from the first connection pipe onto the second drive unit. As a result, it is possible to further suppress the second drive unit of the second valve from malfunctioning due to the condensed water.

[0013] (7) The air conditioner further includes an adjustment member provided on the first connection pipe for adjusting the dripping position of the condensed water from the first connection pipe, the second valve is disposed below the first connection pipe, the second drive unit is preferably arranged avoiding a position below the dripping position. With such a configuration, even if the condensed water generated in the first valve flows into the first connection pipe, it is possible to suppress the condensed water from dripping from the first connection pipe onto the second drive unit. As a result, it is possible to further suppress the second drive unit of the second valve from malfunctioning due to the condensed water.

[0014] (8) The air conditioner further includes a harness having one end connected to the first drive unit, The harness preferably has a trap portion that bends downward in the middle thereof. With such a configuration, even if the other end side of the harness contacts one surface of the refrigerant flow path unit, the dew condensation water flowing along the harness from that surface drips from the lowermost part of the trap portion. Thereby, it is possible to suppress the dew condensation water generated on one surface of the refrigerant flow path unit from flowing along the harness to the first drive unit. As a result, it is possible to further suppress the first drive unit from malfunctioning due to dew condensation water.

Modes for Carrying Out the Invention

[0016] Hereinafter, embodiments will be described with reference to the accompanying drawings. [First Embodiment] FIG. 1 is a perspective view of an air conditioner according to a first embodiment of the present disclosure. The air conditioner 1 is, for example, a building-type multi-type air conditioner installed in a building. The air conditioner 1 can perform cooling and heating of an indoor space to be air-conditioned by performing a vapor compression refrigeration cycle operation. The air conditioner 1 includes an outdoor unit 2 disposed outdoors and an indoor unit disposed indoors. FIG. 1 shows the outdoor unit 2 of the air conditioner 1.

[0017] The outdoor unit 2 includes a casing 3. The casing 3 is formed in a rectangular parallelepiped shape and is formed in a rectangular shape in plan view. The casing 3 has a bottom plate 4, support columns 5, a front panel 6, and the like. Inside the casing 3, a refrigerant flow path unit 10, a compressor 61, an accumulator 62, a heat exchanger 63, a fan 64, a four-way switching valve 65 (see FIG. 2), an electric valve 66 (see FIG. 2), and the like are accommodated.

[0018] FIG. 2 is a perspective view of the refrigerant flow path unit 10 viewed from one side. FIG. 3 is a perspective view of the refrigerant flow path unit 10 viewed from the other side. Devices such as a compressor 61, an accumulator 62, a heat exchanger 63, a four-way switching valve 65, and an electric valve 66 are connected to the refrigerant flow path unit 10. For example, functional components such as a four-way switching valve 65 and an electric valve 66 are connected to one surface of the refrigerant flow path unit 10.

[0019] FIG. 4 is a partial cross-sectional view of the refrigerant flow path unit 10. The refrigerant flow path unit 10 includes a unit body 11, a first joint pipe 12, and a second joint pipe 13. The unit body 11 has a plurality of plates 21, 22, 23. The plurality of plates 21, 22, 23 are laminated and joined to each other. The plates 21, 22, 23 of the present embodiment are made of stainless steel. A refrigerant flow path 15 is formed inside the unit body 11. Hereinafter, the direction in which the plurality of plates 21, 22, 23 are laminated is also referred to as the first direction. The direction along the plate surface of the plates 21, 22, 23 (the direction orthogonal to the first direction) is also referred to as the second direction. The direction orthogonal to the first direction and orthogonal to the second direction is also referred to as the third direction (see FIG. 2).

[0020] The plurality of plates 21, 22, 23 include a first plate 21, a second plate 22 laminated on the first plate 21, and a third plate 23 laminated on the second plate 22. The adjacent plates 21, 22, 23 are joined by brazing.

[0021] The first plate 21 is disposed at both ends of the unit body 11 in the first direction. The first plate 21 is formed thinner than the other second and third plates 22, 23. A plurality of first openings 21a are formed in the first plate 21. The first openings 21a are circular holes penetrating the first plate 21.

[0022] The second plate 22 is located second from both ends of the unit body 11 in the first direction. The second plate 22 is formed thicker than the first plate 21. A plurality of second openings 22a are formed in the second plate 22. The second openings 22a are circular holes penetrating the second plate 22. The second openings 22a communicate with the first openings 21a of the first plate 21.

[0023] The third plate 23 is disposed between two second plates 22 spaced apart in the first direction. In the present embodiment, three third plates 23 are laminated between the two second plates 22. The third plate 23 is formed to have the same thickness as the second plate 22.

[0024] A third opening 23a that constitutes the refrigerant flow path 15 is formed in the third plate 23. The third opening 23a is a hole penetrating each third plate 23 or a slit extending in the second direction. In the example shown in FIG. 4, the third opening 23a is formed in a range spanning two second openings 22a provided on one side in the first direction. The third opening 23a communicates with the second openings 22a of the second plate 22.

[0025] The unit body 11 of the refrigerant flow path unit 10 in the present embodiment is composed of a plurality of plate-like members (plates 21, 22, 23), but it is not limited thereto, and it may be composed of members other than plate-like members.

[0026] The first joint pipe 12 is attached to the first plate 21 and the second plate 22 arranged on one side in the first direction (the upper side in FIG. 4). The first joint pipe 12 is, for example, a straight joint pipe extending in the first direction. A connecting pipe 50 is joined to one end of the first joint pipe 12 by brazing. This connecting pipe 50 is, for example, a refrigerant pipe extending from a four-way switching valve 65 or an electric valve 66 as shown in FIG. 2. The other end of the first joint pipe 12 is inserted into the first opening 21a and the second opening 22a and joined to the first plate 21 and the second plate 22 by brazing.

[0027] The second joint pipe 13 is attached to the first plate 21 and the second plate 22 arranged on the other side in the first direction (the lower side in FIG. 4). The second joint pipe 13 is, for example, an elbow-shaped joint pipe that bends at a right angle. One end of the second joint pipe 13 is inserted into the first opening 21a and the second opening 22a and joined to the first plate 21 and the second plate 22 by brazing. A connecting pipe 50 is joined to the other end of the second joint pipe 13 by brazing. This connecting pipe 50 is, for example, a refrigerant pipe connected to a container such as a compressor 61 or an accumulator 62. The refrigerant flow path unit 10 may be composed only of the unit body 11 without including the first joint pipe 12 and the second joint pipe 13. In this case, the refrigerant pipe 50 is directly connected to the unit body 11.

[0028] As shown in FIGS. 2 and 3, the refrigerant flow path unit 10 in the present embodiment is supported by a support base 70 from below in an upright posture with the plate surface (one surface) of the unit body 11 along the vertical direction. The support base 70 is fixed to the bottom plate 4 of the casing 3.

[0029] FIG. 5 is a side view of the refrigerant flow path unit 10 showing the positional relationship between the connecting pipe 50 and the electric valve 66. In the refrigerant flow path unit 10 of the present embodiment, a plurality of electric valves 66 are connected via a plurality of connecting pipes 50. In FIG. 5, illustration of devices other than the connecting pipe 50 and the electric valve 66 connected to the refrigerant flow path unit 10 is omitted (the same applies to FIGS. 6 and 7).

[0030] The plurality of electric valves 66 include a first electric valve (first valve) 67 and a second electric valve (second valve) 68. The first electric valve 67 includes a first valve body 67a and a first motor (first driving unit) 67b. The first motor 67b is an electric motor that drives a valve body (not shown) provided inside the first valve body 67a. The first motor 67b is attached to the upper surface of the first valve body 67a. The outer diameter of the first motor 67b is larger than the outer diameter of the first valve body 67a.

[0031] The second electric valve 68 is disposed below the first electric valve 67. The second electric valve 68 includes a second valve body 68a and a second motor (second driving unit) 68b. The second motor 68b is an electric motor that drives a valve body (not shown) provided inside the second valve body 68a. The second motor 68b is attached to the upper surface of the second valve body 68a. The outer diameter of the second motor 68b is larger than the outer diameter of the second valve body 68a.

[0032] Rainwater that enters from the upper side of the casing 3 easily adheres to the first motor 67b and the second motor 68b. Therefore, as a waterproof measure, the first motor 67b and the second motor 68b are resin-molded. However, if a large amount of condensed water generated in the refrigerant flow path unit 10 or the like adheres to these resin-molded motors 67b and 68b, the mold resin may crack due to the heat shock that rapidly cools the motors 67b and 68b. Therefore, in the present embodiment, various measures are taken to suppress the adhesion of condensed water to the first motor 67b and the second motor 68b. These measures will be described together below.

[0033] One end of a first harness 41 is connected to the lower surface of a first motor 67b. The other end of the first harness 41 is connected to an electrical component box (not shown). The first harness 41 has a trap portion 41a that bends downward in the middle thereof. The trap portion 41a is configured to drip condensed water flowing through the first harness 41 from its lowermost part.

[0034] Similarly, one end of a second harness 42 is connected to the lower surface of a second motor 68b. The other end of the second harness 42 is connected to an electrical component box (not shown). The second harness 42 has a trap portion 42a that bends downward in the middle thereof. The trap portion 42a is configured to drip condensed water flowing through the second harness 42 from its lowermost part.

[0035] The plurality of connection pipes 50 includes a first connection pipe 51 and a second connection pipe 52. The first connection pipe 51 connects the first electric valve 67 and the refrigerant flow path unit 10. The second connection pipe 52 connects the second electric valve 68 and the refrigerant flow path unit 10.

[0036] The first connection pipe 51 has an upper pipe portion 511 and a lower pipe portion 512. The upper pipe portion 511 extends horizontally from the side surface of the first valve body 67a and is connected to the first joint pipe 12 of the refrigerant flow path unit 10. The lower pipe portion 512 is disposed below the upper pipe portion 512.

[0037] The lower pipe portion 512 of the present embodiment has a first portion 513, a second portion 514, a third portion 515, and a fourth portion 516. The first portion 513 extends downward from the lower surface of the first valve body 67a. The second portion 514 bends from the lower end of the first portion 513 toward the other side in the first direction (the unit body 11 side). The third portion 515 extends obliquely upward toward the unit body 11 from the end on the other side in the first direction in the second portion 514. The fourth portion 516 extends horizontally from the end on the other side in the first direction in the third portion 515 and is connected to the first joint pipe 12 of the refrigerant flow path unit 10.

[0038] The refrigerant flows from one side of the upper pipe portion 511 and the lower pipe portion 512, through the first valve body 67a, to the other side of the upper pipe portion 511 and the lower pipe portion 512. By connecting the upper pipe portion 511 and the lower pipe portion 512 to the first valve body 67a as described above, the first motor 67b is disposed above the first connecting pipe 51.

[0039] The second connecting pipe 52 has an upper pipe portion 521 and a lower pipe portion 522. The upper pipe portion 521 extends horizontally from the second valve body 68a and is connected to the first joint pipe 12 of the refrigerant flow path unit 10. The lower pipe portion 522 is disposed below the upper pipe portion 521. The lower pipe portion 522 extends downward from the lower surface of the second valve body 68a, then bends to the other side in the first direction and extends horizontally, and is connected to the first joint pipe 12 of the refrigerant flow path unit 10.

[0040] The refrigerant flows from one side of the upper pipe portion 521 and the lower pipe portion 522, through the second valve body 68a, to the other side of the upper pipe portion 521 and the lower pipe portion 522. By connecting the upper pipe portion 521 and the lower pipe portion 522 to the second valve body 68a as described above, the second motor 68b is disposed above the second connecting pipe 52.

[0041] The second electric valve 68 is disposed below the lower pipe portion 512 of the first connecting pipe 51. The second motor 68b of the second electric valve 68 is disposed avoiding the position below the lowermost part of the first connecting pipe 51. The "lowermost part" of the first connecting pipe 51 refers to the portion located at the lowermost position of the first connecting pipe 51. The lowermost part of the first connecting pipe 51 in the present embodiment is the lowermost point 514a of the outer peripheral surface of the second portion 514 in the lower pipe portion 512. The second motor 68b is disposed avoiding the position below the lowermost point 514a of the lower pipe portion 512.

[0042] In the present embodiment, in a plan view (see FIG. 6), by shifting the entire second motorized valve 68 to one side in the third direction with respect to the first motorized valve 67 and the first connecting pipe 51, the second motor 68b is arranged avoiding the position below the lowest point 514a. Note that if the second motor 68b is arranged avoiding the position below the lowest point 514a, it is not limited to the arrangement of the present embodiment. For example, in a plan view, even if the entire second motorized valve 68 is arranged overlapping the first motorized valve 67, the lower pipe portion 512 may be arranged such that its lowest point 514a is displaced in the first direction or the third direction with respect to the second motor 68b.

[0043] Note that the lower pipe portion 512 of the first connecting pipe 51 is not limited to the shape of the present embodiment. For example, the lower pipe portion 512 may be formed by extending downward from the first valve body 67a and then bending to the other side in the first direction and extending horizontally, similar to the lower pipe portion 522 of the second connecting pipe 52. In that case, the lowest line extending in the first direction on the outer peripheral surface of the horizontal portion of the lower pipe portion 512 becomes the lowermost portion of the lower pipe portion 512. The second motor 68b is arranged avoiding the position below the lowest line of the lower pipe portion 512.

[0044] FIG. 6 is a plan view of the refrigerant flow path unit 10 showing the positional relationship between the connecting pipe 50 and the motorized valve 66. In FIG. 6, illustration of the first harness 41 and the second harness 42 is omitted. In the plan view of FIG. 6, the first motorized valve 67 and the second motorized valve 68 are arranged shifted from each other in the first direction and the third direction. Thereby, the first motor 67b and the second motor 68b are arranged avoiding the positions overlapping each other in the plan view.

[0045] In the plan view of FIG. 6, the second motorized valve 68 is arranged on one side in the third direction (the right side in FIG. 6) with respect to the first connecting pipe 51. Thereby, the second motor 68b is arranged avoiding the position overlapping the first connecting pipe 51 in the plan view.

[0046] [Operational Effects of the First Embodiment] According to the air conditioner 1 of the present embodiment, the first motor 67b of the first electric valve 67 is disposed above the first connecting pipe 51. Thereby, even if the dew condensation water generated on one surface of the refrigerant flow path unit 10 (unit main body 11) flows to the first electric valve 67 along the first connecting pipe 51, it is possible to suppress the dew condensation water from flowing to the first motor 67b. As a result, it is possible to suppress the first motor 67b of the first electric valve 67 from malfunctioning due to dew condensation water.

[0047] The second motor 68b of the second electric valve 68 is disposed above the second connecting pipe 52. Thereby, even if the dew condensation water generated on the plate surface of the refrigerant flow path unit 10 flows to the second electric valve 68 along the second connecting pipe 52, it is possible to suppress the dew condensation water from flowing to the second motor 68b. As a result, it is possible to suppress the second motor 68b of the second electric valve 68 from malfunctioning due to dew condensation water.

[0048] The second electric valve 68 is disposed below the first electric valve 67, and the first motor 67b and the second motor 68b are disposed so as to avoid overlapping positions in a plan view. Thereby, it is possible to suppress the dew condensation water generated in the upper first electric valve 67 from dripping onto the second motor 68b of the lower second electric valve 68. As a result, it is possible to suppress the second motor 68b from malfunctioning due to dew condensation water. Further, compared with the case where the first electric valve 67 and the second electric valve 68 are disposed adjacent to each other in the horizontal direction at the same height position, it is possible to easily access the refrigerant flow path unit 10 from both horizontal sides (left and right sides in FIG. 6) of the upper first electric valve 67. Thereby, maintenance work such as that on the refrigerant flow path unit 10 can be easily performed.

[0049] The second motor 68b of the second electric valve 68 is disposed so as to avoid a position below the lowest point 514a of the lower pipe portion 512 in the first connecting pipe 51. Thereby, even if the dew condensation water generated in the first electric valve 67 flows into the lower pipe portion 512, it is possible to suppress the dew condensation water from dripping from the lowest point 514a of the lower pipe portion 512 to the second motor 68b. As a result, it is possible to suppress the second motor 68b from malfunctioning due to dew condensation water.

[0050] The second motor 68b of the second electric valve 68 is arranged avoiding the position overlapping with the first connecting pipe 51 in a plan view. Thereby, even if the dew condensation water generated on the plate surface of the first electric valve 67 or the refrigerant flow path unit 10 flows to the first connecting pipe 51, it is possible to suppress the dew condensation water from dripping from the first connecting pipe 51 to the second motor 68b. As a result, it is possible to further suppress the second motor 68b from malfunctioning due to the dew condensation water.

[0051] The first harness 41 having one end connected to the first motor 67b has a trap portion 41a bent downward in the middle thereof. Thereby, even if the other end side of the first harness 41 is in contact with the plate surface of the refrigerant flow path unit 10, the dew condensation water flowing along the first harness 41 from the plate surface drips from the lowermost part of the trap portion 41a. Thereby, it is possible to suppress the dew condensation water generated on the plate surface of the refrigerant flow path unit 10 from flowing to the first motor 67b along the first harness 41. As a result, it is possible to further suppress the first motor 67b from malfunctioning due to the dew condensation water.

[0052] Similarly, the second harness 42 having one end connected to the second motor 68b has a trap portion 42a bent downward in the middle thereof. Thereby, even if the other end side of the second harness 42 is in contact with the plate surface of the refrigerant flow path unit 10, the dew condensation water flowing along the second harness 42 from the plate surface drips from the lowermost part of the trap portion 42a. Thereby, it is possible to suppress the dew condensation water generated on the plate surface of the refrigerant flow path unit 10 from flowing to the second motor 68b along the second harness 42. As a result, it is possible to further suppress the second motor 68b from malfunctioning due to the dew condensation water.

[0053] [Second Embodiment] FIG. 7 is a side view of the refrigerant flow path unit 10 showing the positional relationship between the connecting pipe 50 and the electric valve 66 in the air conditioner according to the second embodiment of the present disclosure. The lower pipe portion 512 of the first connecting pipe 51 in the present embodiment has a first portion 517, a second portion 518, and a third portion 519.

[0054] The first part 517 extends downward from the lower surface of the first valve body 67a. The second part 518 curves from the lower end of the first part 517 to the other side in the first direction. The third part 519 extends horizontally from the end on the other side in the first direction in the second part 518 toward the unit body 11 and is connected to the first joint pipe 12 of the refrigerant flow path unit 10.

[0055] FIG. 8 is a plan view of the refrigerant flow path unit 10 showing the positional relationship between the connection pipe 50 and the electric valve 66 in the present embodiment. In FIG. 8, the illustration of the upper pipe portion 511 of the first connection pipe 51 is omitted. The second electric valve 68 in the present embodiment is disposed at a position below the third part 519 in the lower pipe portion 512 of the first connection pipe 51.

[0056] As shown in FIGS. 7 and 8, a heat insulating material 45 is provided on the lower pipe portion 512. The heat insulating material 45 is formed in a cylindrical shape and covers the outer periphery of the lower pipe portion 512. The heat insulating material 45 of the present embodiment covers a part of the first part 517 (the lower part in FIG. 7), the whole of the second part 518, and a part of the third part 519 (the right part in FIG. 7) of the lower pipe portion 512.

[0057] The condensed water generated in the first electric valve 67 flows from between the first part 517 of the lower pipe portion 512 and the heat insulating material 45, passes between the second part 518 and the heat insulating material 45, and flows toward the other side in the first direction between the third part 519 and the heat insulating material 45. The condensed water flowing between the third part 519 and the heat insulating material 45 drips from the end 45a on the other side in the first direction of the heat insulating material 45. Therefore, by positioning the end 45a of the heat insulating material 45 at an arbitrary position in the first direction, the dripping position of the condensed water flowing along the lower pipe portion 512 can be adjusted. Thereby, the heat insulating material 45 functions as an adjusting member for adjusting the dripping position of the condensed water from the lower pipe portion 512.

[0058] The second electric valve 68 is arranged to be shifted to one side in the first direction with respect to the dripping position of the condensed water from the lower pipe portion 512 (the end portion 45a of the heat insulating material 45). As a result, the second motor 68b is arranged to avoid the position below the dripping position. Since the other configurations of the second embodiment are the same as those of the first embodiment, the description thereof is omitted.

[0059] In the present embodiment, the heat insulating material 45 is used as the adjusting member for adjusting the dripping position of the condensed water, but the present invention is not limited thereto. For example, a water guiding member that guides the condensed water flowing through the lower pipe portion 512 to a predetermined dripping position may be used as the adjusting member.

[0060] [Operation and Effect of Second Embodiment] Also in the air conditioner 1 of the present embodiment, the same operation and effect as those of the first embodiment are achieved. Further, the second motor 68b of the second electric valve 68 is arranged to avoid the position below the dripping position of the condensed water from the lower pipe portion 512 of the first connecting pipe 51 (the end portion 45a of the heat insulating material 45). As a result, even if the condensed water generated in the first electric valve 67 flows to the lower pipe portion 512, it is possible to suppress the condensed water from dripping from the end portion 45a of the heat insulating material 45 to the second motor 68b. As a result, it is possible to suppress the second motor 68b from malfunctioning due to the condensed water.

[0061] [Others] The first valve and the second valve are not limited to electric valves, and may be, for example, solenoid valves. In this case, the solenoids of these solenoid valves serve as the first driving portion and the second driving portion.
