[0013] 6(a) is an enlarged view of part C in FIG. 4, FIG. 6(b) is an enlarged view of part D in FIG. 4, and FIG. 7 is an overall view of the heat pump heat source machine in the first embodiment.

[0014] Hereinafter, the configuration of the heat pump heat source machine in the first embodiment will be described with reference to Figs. 1 to 7.

[0015] The heat pump heat source unit in embodiment 1 is an outdoor unit that includes at least a compressor 2, a radiator (not shown), a pressure reducing device (not shown), and a heat source side heat exchanger 3, out of a refrigerant circuit 4 that is made up of the compressor 2, the heat source side heat exchanger 3, and a blower 5 that generates air for heat exchange with the heat source side heat exchanger 3.

[0016] In the main body 1, a compressor 2 and a blower 5 are arranged in parallel in the horizontal direction on a bottom plate 10, and a heat source side heat exchanger 3 is arranged at least behind them. A top plate 9 is provided above them. The blower 5 is composed of a motor and a propeller fan.

[0017] A partition plate 6 is provided to separate the compressor 2 side from the blower 5 side, i.e., to divide the space horizontally, forming an air blowing chamber in which the blower 5 is arranged and a machine room in which the compressor 2 is arranged.

[0018] Further, a compressor-side housing 7 that covers the compressor 2 from the front and a blower-side housing that covers the blower 5 from the front and has an air outlet are arranged in parallel in the horizontal direction.

[0019] Further, outside the compressor side housing 7, a lattice-shaped first grill 11, which is the housing on the compressor 2 side, is provided.

[0020] Further, outside the blower device side housing 8, a second grille 12 is provided on the blower device 5 side housing, which is in a lattice shape and has ventilation performance.

[0021] The first grill 11 and the second grill 12 are disposed adjacent to each other in parallel in the horizontal direction, and form the front part of the main body 1.

[0022] Enlarged views of part A in FIG. 3, part B in FIG. 4, part C in FIG. 4, and part D in FIG. 4 are shown in FIG. 5(a), FIG. 5(b), FIG. 6(a), and FIG. 6(b), respectively.

[0023] 4, 5(a), and 5(b), the first grill 11 has a side surface that contacts the second grill 12 and is provided with a plurality of protrusions 11a serving as engaging portions. The second grill 12 has a side surface that contacts the first grill 11 and is provided with a plurality of insertion portions 12a serving as engaged portions. 6(a), a plurality of L-shaped fixing portions 12b are provided on the outer surface of the compressor side housing 7 on the inner side of the first grille 11. Then, a threaded portion 12c is provided on the protruding side of the L-shaped fixing portion 12b.

[0024] In FIG. 6(b), a plurality of through holes 11b are provided only in the portion (side surface portion) of the first grille 11 that forms the side surface of the main body 1.

[0025] Next, a configuration for attaching and detaching the first grill 11 will be described with reference to Figs.

[0026] The first grill 11 is temporarily fixed to the main body 1 by inserting the protrusion 11a, which is the engaging portion provided on the side portion of the first grill 11, into the insertion portion 12a, which is the engaging portion provided on the side portion of the second grill 12, and bringing the first grill 11 closer to the second grill 12.

[0027] At this time, the positions of the multiple threaded portions 12c provided on the protruding sides of the multiple L-shaped fixing portions 12b provided on the compressor side housing 7 coincide with the positions of the multiple through-holes 11b provided in the first grill 11, so that the first grill 11 can be easily attached to the second grill 12 by fixing the threaded portions 12c and the through-holes 11b with a fastening means such as a screw.

[0028] Furthermore, when removing the first grill 11 from the second grill 12, the first grill 11 can be easily removed from the second grill 12 by removing the fastening means such as screws and moving the first grill 11 away from the second grill 12.

[0029] That is, the portion of the first grill 11 that is fastened to the main body 1 by the fastening means (the through portion 11b) is only the portion of the first grill 11 that forms the side surface of the main body 1 (the side surface portion).

[0030] Alternatively, the insertion portion 12a, which is the engaged portion, may be provided on the bottom plate 10, and the through portion 11b may be provided only on the portion of the first grill 11 that forms the top surface of the main body 1.

[0031] Furthermore, the through-holes 11b may be provided in both the portion of the first grill 11 that forms the top surface of the main body 1 and the portion of the first grill 11 that forms the side surface of the main body 1.

[0032] [1-2. Effects, etc.] As described above, in this embodiment, the heat pump heat source unit comprises a refrigerant circuit 4 consisting of at least the compressor 2 and the heat source side heat exchanger 3, a blower 5 that generates air to exchange heat with the heat source side heat exchanger 3, a partition plate 6 that separates the compressor 2 from the blower 5, a first grill 11 that covers the compressor 2 from the front, a second grill 12 that is arranged in parallel with the first grill 11 and covers the blower 5 from the front, and a main body 1 in which at least the compressor 2 and the blower 5 are housed, and the portion where the first grill 11 is fastened to the main body 1 by fastening means is only the portion where the first grill 11 forms the top and / or side surface of the main body 1.

[0033] As a result, since no part to be fastened by a fastening means is provided on the front part of the main body 1, a heat pump heat source unit with excellent design can be provided.

[0034] Furthermore, when maintenance is required, the first grill 11 can be removed from the main body 1 simply by removing the fastening means of the first grill 11, thereby providing a heat pump heat source machine that is easy to maintain.

[0035] The first grill 11 has an engaging portion 11a on its side surface, and the second grill 12 has an engaged portion 12a on its side surface.

[0036] This allows the first grill 11 and the second grill 12, which form the front portion of the main body 1 and are arranged in parallel, to be arranged adjacent to each other without any gaps, etc., thereby providing a heat pump heat source unit with excellent design.

[0037] Furthermore, since no fastening means is used to support the first grill 11 on the second grill 12, the first grill 11 can be easily removed from the main body 1, thereby providing a heat pump heat source machine with excellent maintainability.

[0038] Furthermore, when performing maintenance inside the machine room in which the compressor 2, etc. are located, it is necessary to remove only the first grill 11, and there is no need to remove the second grill 12, so a heat pump heat source machine with excellent maintainability can be provided.

[0039] Furthermore, when performing maintenance on the machine room in which the compressor 2, etc. are located while the heat pump heat source unit is being test-run or in operation, the propeller fan of the blower unit 5 is rotating, but since the second grill 12 is in an attached state, it serves as a guard for the propeller fan of the blower unit 5, thereby providing a heat pump heat source unit with excellent safety.

[0040] Further, on the inner side of the first grill 11, there is provided a compressor side housing 7 which covers the compressor 2 from the front and has a fixing portion 12b on its outer surface, and the fixing portion 12b and a portion which forms the top surface and / or side surface of the main body 1 of the first grill 11 are fastened to each other by a fastening means.

[0041] As a result, since no part to be fastened by a fastening means is provided on the front part of the main body 1, a heat pump heat source unit with excellent design can be provided.

[0042] Furthermore, since the front of the compressor 2 has a double housing configuration, it is possible to provide a heat pump heat source machine that realizes reduced vibration and noise. [Industrial Applicability]

[0043] INDUSTRIAL APPLICABILITY The present disclosure can provide a heat pump heat source machine that is excellent in design and maintainability, and is therefore particularly useful for heat pump water heaters and heat pump hot water heating machines. [Explanation of symbols]
