[0014] A configuration of the heat pump heat source device of the embodiment will be described below based on Figs. 1 to 7.

[0015] The heat pump heat source device in the embodiment is an outdoor unit including at least a compressor 2 and a heat source-side heat exchanger 3 of a refrigerant circuit 4 which is composed of the compressor 2, a radiator (not shown), a decompressor (not shown) and the heat source-side heat exchanger 3, and a blower 5 for generating air which exchanges heat with heat source-side heat exchanger 3.

[0016] The compressor 2 and the blower 5 are placed horizontally in parallel on a bottom plate 10 in a main body 1 of the outdoor unit. The heat source-side heat exchanger 3 is placed at least in the rear of the blower 5. A top plate 9 is provided above the compressor 2 and the blower 5. The blower 5 is composed of a motor and a propeller fan.

[0017] A partition plate 6 is provided to partition the compressor 2 and the blower 5 from each other, i.e., to partition the compressor 2 and the blower 5 from each other in the horizontal direction. A blast room where the blower 5 is placed and a machine room where the compressor 2 is placed are formed.

[0018] A compressor-side casing 7 covering the compressor 2 from front and a blower-side casing 8 covering the blower 5 from front and having a blast port are placed in parallel in the horizontal direction.

[0019] A lattice-shaped first grill 11 is provided outside the compressor-side casing 7. The first grill 11 is a casing on the side of the compressor 2.

[0020] A lattice-shaped second grill 12 is provided outside the blower-side casing 8. The second grill 12 is a casing on the side of the blower 5. The second grill 12 has ventilating performance.

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

[0022] Figs. 5(a), 5(b), 6(a) and 6(b) respectively show enlarged views of a portion A in Fig. 3, a portion B in Fig. 4, a portion C in Fig. 4 and a portion D in Fig. 4.

[0023] In Figs. 4, 5(a) and 5(b), a plurality of projections 11a which are engaging portions are provided on a side surface of the first grill 11 which is in contact with the second grill 12. A plurality of inserting portions 12a which are engaged portions are provided on a side surface of the second grill 12 which is in contact with the first grill 11.

[0024] In Fig. 6(a), a plurality of L-shaped fixing portions 12b are provided on an outer surface of the compressor-side casing 7 on the inner side of the first grill 11. Thread portions 12c which are threaded are provided in projecting sides of the L-shaped fixing portions 12b.

[0025] In Fig. 6(b), a plurality of penetrating portions 11b are provided only on a portion (side surface) where the first grill 11 forms a side surface of the main body 1.

[0026] Next, attaching and detaching configurations of the first grill 11 will be described based on Figs. 3 to 7.

[0027] The projections 11a which are the engaging portions provided on the side surface of the first grill 11 are inserted into the inserting portions 12a which are engaged portions provided on the side surface of the second grill 12. According to this, by bringing the first grill 11 close to the second grill 12, the first grill 11 is temporarily fixed to the main body 1.

[0028] At that time, positions of the plurality of thread portions 12c provided on the projecting sides of the plurality of L-shaped fixing portions 12b provided on the compressor-side casing 7 and positions of the plurality of penetrating portions 11b provided on the first grill 11 coincide with each other. Therefore, by fixing the thread portions 12c and the penetrating portions 11b to each other by fastening means such as screws, it is possible to easily attach the first grill 11 to the second grill 12.

[0029] When the first grill 11 is detached from the second grill 12, the fastening means is detached and the first grill 11 is separated from the second grill 12. According to this, the first grill 11 can easily be detached from the second grill 12.

[0030] That is, portions (penetrating portions 11b) where the first grill 11 is fastened by the fastening means are only a portion (side surface) where the first grill 11 forms the side surface of the main body 1.

[0031] The inserting portions 12a which are the engaged portions may be provided on the bottom plate 10, and the penetrating portions 11b may be provided only on the portion where the first grill 11 forms a ceiling surface of the main body 1.

[0032] The penetrating portions 11b may be provided on both the portion where the first grill 11 forms the ceiling surface of the main body and the portion where the first grill 11 forms the side surface of the main body 1.

[1-2. Effect and the like]

[0033] In the embodiment, as described above, the heat pump heat source device includes at least the compressor 2, the refrigerant circuit 4 composed of the heat source-side heat exchanger 3, the blower 5 for generating air which exchanges heat with the heat source-side heat exchanger 3, the partition plate 6 which partitions the compressor 2 and the blower 5 from each other, the first grill 11 which covers the compressor 2 from front, the second grill 12 which is placed in parallel to the first grill 11 and which covers the blower 5 from front, and the main body 1 provided therein with at least the compressor 2 and the blower 5, and the portion where the first grill 11 is fastened to the main body 1 by the fastening means is only the portion where the first grill 11 forms the ceiling surface and/or the side surface of the main body 1.

[0034] According to this, the portion which is fastened by the fastening means is not provided on the front surface of the main body 1. Therefore, it is possible to provide the heat pump heat source device which is excellent in design.

[0035] When maintenance is necessary, the first grill 11 can be detached from the main body 1 only by detaching the fastening means of the first grill 11. Therefore, it is possible to provide the heat pump heat source device which is excellent in maintainability.

[0036] The engaging portions 11a are provided on the side surface of the first grill 11, and the engaged portions 12a are provided on the side surface of the second grill 12.

[0037] According to this, the first grill 11 and the second grill 12 which form a front surface of the main body 1 and which are placed in parallel to each other can be placed in adjacent to each other without a gap. Therefore, it is possible to provide the heat pump heat source device which is excellent in design.

[0038] Further, since fastening means is not used to support the first grill 11 on the second grill 12, it is possible to easily detach the first grill 11 from the main body 1. Therefore, it is possible to provide the heat pump heat source device which is excellent in maintainability.

[0039] When maintenance in the machine room where the compressor 2 and the like are placed is carried out, it is only necessary to detach only the first grill 11, and it is unnecessary to detach the second grill 12. Therefore, it is possible to provide the heat pump heat source device which is excellent in maintainability.

[0040] Further, when maintenance in the machine room where the compressor 2 and the like are placed is carried out while operating or test-operating the heat pump heat source device, the propeller fan of the blower 5 is rotating, but the second grill 12 is attached. Therefore, the propeller fan of the blower 5 is guarded, and it is possible to provide a safe heat pump heat source device.

[0041] The compressor-side casing 7 is provided on the inner side of the first grill 11. The compressor-side casing 7 covers the compressor 2 from front and the outer surface of the compressor-side casing 7 has the fixing portions 12b. The fixing portions 12b and the portion where the first grill 11 forms the ceiling surface and/or the side surface of the main body 1 are fastened to each other through the fastening means.

[0042] According to this, the portion which is fastened by the fastening means is not provided on the front surface of the main body 1. Therefore, it is possible to provide the heat pump heat source device which is excellent in design.

[0043] Further, a front portion of the compressor 2 is of a double-casing structure. Therefore, it is possible to provide a heat pump heat source device which can reduce vibration and noise.

[INDUSTRIAL APPLICABILITY]

[0044] The present disclosure can provide a heat pump heat source device which is excellent in design and maintainability. Therefore, the present invention is useful especially in a heat pump hot water supply device and a heat pump type hydronic heater.
