[0003] [Patent Document 1] International Publication No. 2018 / 011939 Summary of the Invention [Problem to be solved by the invention]

[0004] The outdoor unit of the air conditioner disclosed in Patent Document 1 has a base covering the bottom of the heat exchanger, which reduces the airflow toward the bottom of the heat exchanger. In particular, in the case of air conditioners installed in buildings, multiple outdoor units must be concentrated in a small area, such as on a rooftop. To reduce installation space, the gaps between the housings cannot be set large, resulting in narrow spaces between adjacent outdoor units. A heat exchanger facing the gap between adjacent outdoor units receives air that flows into the gap between the two outdoor units, but the lower part of a heat exchanger located near the installation surface has an issue in that the amount of air that flows in is limited by the base covering the bottom of the heat exchanger.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an outdoor unit of a refrigeration cycle device that can ensure air flow to the part of the heat exchanger located at the bottom of the housing even when the heat exchanger is centrally arranged. [Means for solving the problem]

[0006] The outdoor unit of a refrigeration cycle apparatus according to the present disclosure includes a housing formed in a rectangular parallelepiped shape, a heat exchanger housed inside the housing and arranged along an open first side surface of the housing, and a blower fan arranged in an upper portion of the housing and discharging air that has passed through the heat exchanger from an upper surface of the housing, wherein the housing has a shape in which adjacent side surfaces of the housing are connected by inclined surfaces at least in an area from a bottom surface of the housing to where the heat exchanger is housed, and the outdoor unit of a refrigeration cycle apparatus includes a base that constitutes the bottom surface and support legs of the housing, and a plurality of pillars that are joined to corners of the base and extend in a height direction of the housing , and of the plurality of pillars, at least the pillar arranged at the end of the first side surface has a lower end joined to the base, a first portion having a surface parallel to the first side surface and located at the end of the first side surface in the width direction, a second portion having a surface parallel to a second side surface adjacent to the first side surface and located at the end of the second side surface in the width direction, and a chamfered portion arranged between the first portion and the second portion and having the inclined surface, and the first portion has a protrusion formed at its lower end and a throttling portion located above the protrusion, and the throttling portion is located closer to the heat exchanger than the protrusion in the direction perpendicular to the first side surface. [Effects of the Invention]

[0007] According to the present disclosure, by providing a constriction portion in the pillar, airflow to the portion of the heat exchanger located at the bottom of the housing can be ensured even when the outdoor units of the refrigeration cycle device are centrally arranged.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals, and their description will be omitted or simplified as appropriate. Furthermore, the shape, size, arrangement, etc. of the configurations shown in each drawing may be changed as appropriate.

[0010] Embodiment 1 Fig. 1 is a perspective view showing the appearance of an outdoor unit 100 of a refrigeration cycle apparatus according to embodiment 1. Fig. 2 is a side view showing a case where the outdoor units 100 of the refrigeration cycle apparatus according to embodiment 1 are centrally arranged.

[0011] As shown in Figures 1 and 2, the outdoor unit 100 of the refrigeration cycle device of embodiment 1 has a vertically placed, approximately rectangular parallelepiped casing 1, a heat exchanger 7 provided along the side of the casing 1, and internal components that form a refrigeration cycle, such as a compressor (not shown), a blower fan 81, an accumulator (not shown), and refrigerant piping (not shown) installed inside the casing 1.

[0012] The housing 1 is a substantially rectangular parallelepiped, and includes a heat exchanger 7 arranged along an open first side surface 1a of the housing 1, and a blower fan 81 arranged on top of the housing 1 and discharging air that has passed through the heat exchanger 7. The housing 1 has a shape in which adjacent side surfaces 1a and 1b of the housing 1 are connected by inclined surfaces 1c at least in the range in the z direction from the bottom surface of the housing 1 to where the heat exchanger 7 is housed. Note that in the housing 1 shown in embodiment 1, inclined surfaces 1c are provided at corners from the bottom surface to the top surface of the rectangular parallelepiped.

[0013] FIG. 3 is a perspective view of the housing 1 according to the first embodiment. The housing 1 includes a base 20, four pillars 4 extending upward (in the z-direction) from corners of the base 20, a front panel 5 covering the side surfaces, and a fan casing 6 provided around a blower fan 81. The base 20, which forms the bottom of the housing 1, includes a bottom plate 2, base legs 3 supporting the housing 1, and a drain pan 8. The four pillars 4 are connected by the fan casing 6 at the top of the housing 1. The structure shown in FIG. 3 is an example, and the four pillars 4 may be connected by a frame including the fan casing 6 and the like. The two pillars 4 at both ends of the second side surface 1b of the housing 1 in the width direction are connected by the front panel 5. In this manner, only some of the four pillars 4 may be connected by the frame.

[0014] FIG. 4 is a perspective view of the bottom plate 2 of the housing 1 according to the first embodiment. As shown in FIGS. 3 and 4, the bottom plate 2 has a substantially rectangular shape and forms the bottom surface of the housing 1. The bottom plate 2 has both ends, from which the peaks 2a and valleys 2b extend, placed and supported by a pair of base legs 3, and is located at a predetermined height above the installation surface 91. An internal component, such as a compressor (not shown), is placed on the top surface of the bottom plate 2. The bottom surface of the bottom plate 2 is curved to form a square wave shape in which the peaks 2a and valleys 2b are alternately connected. The top surfaces of the peaks 2a and the bottom surfaces of the valleys 2b are each flat and formed to be substantially parallel. In other words, the cross-sectional shape of the bottom surface of the bottom plate 2 may be a rectangular wave shape, a trapezoidal wave shape, or any other wave shape. By forming the bottom surface of the bottom plate 2 into a wave shape, the rigidity of the bottom plate 2 is increased when a bending moment is applied in the surface direction, thereby increasing its strength. The bottom plate 2 also has flanges 22 formed by bending upward both ends in the direction (x direction) in which the peaks 2a and valleys 2b are alternately connected.

[0015] The bottom plate 2 is also formed with drain holes for draining to the outside drain water that is generated in the heat exchanger 7 and flows onto the bottom surface of the bottom plate 2. A drain pan 8 is placed on the upper surface of the bottom plate 2 (see FIG. 6), and is located below the heat exchanger 7.

[0016] Fig. 5 is a perspective view of the base leg 3 of the housing 1 according to the first embodiment. As shown in Fig. 3, the base leg 3 is disposed below the bottom plate 2 to support the bottom plate 2. The base leg 3 is formed, for example, by bending a steel plate, and extends in the direction (x direction) in which the peaks 2a and valleys 2b of the bottom plate 2 are alternately arranged. The base leg 3 protrudes in the x direction from the bottom plate 2.

[0017] The base leg 3 has a planar installation portion 30 that is installed on the installation surface of the outdoor unit 100 of the refrigeration cycle apparatus, a rising portion 31 that rises upward from one end edge along the longitudinal direction (x direction) of the installation portion 30, a support portion 32 that is bent horizontally from the upper end edge along the longitudinal direction (x direction) of the rising portion 31, and a wall portion 33 that rises upward from the tip edge along the longitudinal direction (x direction) of the support portion 32. The installation portion 30, the rising portion 31, and the support portion 32 form a substantially C-shaped vertical cross section of the base leg 3. Note that the horizontal direction is a concept that includes approximately horizontal and does not have to be strictly horizontal.

[0018] The end portions of the bottom plate 2, from which the peak portions 2a and valley portions 2b extend, are placed on the support portion 32. The lower surfaces of the valley portions 2b of the bottom plate 2 abut against the upper surface of the support portion 32. The bottom plate 2 and the support portion 32 are formed with a positioning mechanism that positions the bottom plate 2 and the support portion 32 when the bottom plate 2 is placed on the support portion 32. The positioning mechanism has first embossments 21 formed on both ends of the valley portions 2b to be placed on the base leg 3, and second embossments 34 formed on the support portion 32. The first embossments 21 are formed so as to protrude upward from the upper surface of the valley portions 2b. A plurality of first embossments 21 are formed at intervals along the direction in which the waveforms are continuous. The second embossments 34 are formed so as to protrude upward from the upper surface of the support portion 32. A plurality of second embossments 34 are formed along the longitudinal direction of the support portion 32. The first embossments 21 and the second embossments 34 fit together when the bottom plate 2 is placed on the support portion 32. The first embossments 21 and the second embossments 34 are joined together with a joining member such as a screw from the underside of the bottom plate 2 while they are fitted together. The head of the joining member is housed inside the recess of the second embossment 34. The outdoor unit 100 of the refrigeration cycle apparatus has a positioning mechanism, which makes it easy to install the bottom plate 2 in a predetermined position. The positions and numbers of the first embossments 21 and the second embossments 34 are not limited to the configuration shown in the figure, and may be changed as appropriate depending on the installation location of the outdoor unit 100 of the refrigeration cycle apparatus or the shape and size of the bottom plate 2, etc.

[0019] The wall portion 33 is formed so that its wall surface faces the end of the bottom plate 2 placed on the support portion 32. As shown in Fig. 3, the wall portion 33 is formed so as to be at approximately the same height as the flange portion 22 of the bottom plate 2, and is arranged so as to surround the periphery of the base 20 that forms the bottom surface of the housing 1 together with the flange portion 22.

[0020] Pillar fixing portions 35 are formed on both ends of the base leg 3 in the x direction. Both ends of the base leg 3 are cut obliquely to match the shape of the inclined surface 1c of the housing 1, and are configured to fit along the chamfered portion 4d of the pillar 4 that forms the inclined surface 1d. The pillar fixing portions 35 are aligned with the chamfered portion 4d of the pillar 4 and are joined to the lower end of the pillar 4 by bolts 42 (see FIG. 6).

[0021] Fig. 6 is an enlarged perspective view of part A of the outdoor unit 100 of the refrigeration cycle device of Fig. 1. Fig. 7 is a perspective view of a corner of the base 20 according to the first embodiment, seen from the inside. Fig. 8 is a perspective view of a pillar 4 of the housing 1 according to the first embodiment. The bottom plate 2 has a rising piece 24 at the corner, and is joined to the pillar 4 with a bolt 41. The base leg 3 and the pillar 4 are joined with a bolt 40. The lower end of the front panel 5 covering the second side surface 1b of the housing 1 is also fixed to the base leg 3 with a bolt 44.

[0022] (Pillar 4) The pillars 4 are fixed to the base 20 and form the four corners of the housing 1. The four pillars 4 are connected at the lower end of the housing 1 by the base 20 and at the upper end of the housing 1 by the fan casing 6, thereby forming the roughly rectangular parallelepiped shape of the housing 1.

[0023] The pillar 4 includes a first portion 4a that forms the end of the first side surface 1a of the housing 1 in the width direction (y direction), a second portion 4e that forms the end of the second side surface 1b in the width direction (x direction), and a chamfered portion 4d that connects the first portion 4a and the second portion 4e. The first portion 4a of the pillar 4 is composed of a protruding portion 4c, an inclined portion 4b, and a tapered portion 4g from below. The lower end of the first portion 4a of the pillar 4 is formed to conform to the shape of the end of the base leg 3, and the protruding portion 4c is formed to protrude perpendicularly (x direction) from the first side surface 1a of the housing 1. A tapered portion 4g is formed above the protruding portion 4c, and is located closer to the heat exchanger 7 than the protruding portion 4c. The tapered portion 4g is joined to the flange portion 22 of the bottom plate 2 with bolts 43. The protruding portion 4c and the tapered portion 4g are connected by the inclined portion 4b, ensuring the strength and rigidity of the pillar 4. The second portion 4e of the pillar 4 is joined to the wall portion 33 of the base leg 3 by a bolt 40. In this way, the pillar 4 is joined to the bottom plate 2 and base leg 3 that form the base 20 using bolts, forming the main framework of the housing 1. The shape of the lower end of the pillar 4 is formed to follow the shape of the end of the base leg 3 in a plan view, and the protruding portion 4c of the pillar 4 is arranged to follow the end surface 36 of the base leg 3 shown in FIG. 5, the chamfered portion 4d is arranged to follow the pillar fixing portion 35, and the second portion 4e is arranged to follow the surface of the wall portion 33.

[0024] FIG. 9 is an explanatory diagram of the cross section BB in FIG. 2. Air flows into a gap 90 between the outdoor units 100 of the two refrigeration cycle devices toward the heat exchanger 7. The gap 90 is the space between the first side surfaces 1a of the outdoor units 100 of the two refrigeration cycle devices arranged facing each other. Air flows in from the second side surface 1b. In the cross section of FIG. 9, the pillar 4 has a chamfered portion 4d, which has a wide air inlet that gradually narrows toward the heat exchanger 7, making it easy for air to flow in. The chamfered portion 4d is a portion that constitutes the inclined surface 1c of the housing 1 and corresponds to the chamfered shape provided at the corners from the bottom surface to the top surface of the housing 1.

[0025] 10 is an enlarged view of portion C in FIG. 2. The portion of the gap 90 close to the installation surface 91 is likely to have less air inflow due to the influence of the installation surface 91. In particular, when the outdoor units 100 of the refrigeration cycle apparatus are installed in a concentrated manner as shown in FIG. 2, the distance between the housings 1 is set small to reduce the installation area. However, the first portion 4a of the pillar 4 has a protrusion 4c at its lower end to ensure a sufficient width dimension of the base leg 3 in the x direction, and a throttle portion 4g above the base leg 3 and the bottom plate 2 to ensure a sufficient width dimension W2 of the gap 90. This ensures a sufficient amount of air inflow even in the lower portion of the heat exchanger 7, which is likely to be affected by the installation surface 91.

[0026] Typically, the spacing between the housings 1 in a concentrated installation is set based on the width W of the gap between the portions where the base legs 3 are installed. For example, the width W of the gap between the portions where the base legs 3 are installed is set to 30 mm. Then, the width W2 of the gap of the throttle portion 4g is set to be larger than 30 mm. This makes it easier for air to flow into the air inlet of the first side surface 1a where the heat exchanger 7 is installed in the outdoor unit 100 of the refrigeration cycle apparatus.

[0027] As shown in FIG. 7 , the lower end of the tapered portion 4g of the pillar 4 is fixed to the end of the flange portion 22 of the bottom plate 2. This allows the drain pan 8, which is fixed to the bottom plate 2, to be positioned as close as possible to the tapered portion 4g of the pillar 4 in the x direction. Accordingly, the tapered portion 4g of the pillar 4 is positioned near the heat exchanger 7 in the x direction. This configuration allows the outdoor unit 100 of the refrigeration cycle apparatus according to Embodiment 1 to have a large gap 90 for supplying air to the heat exchanger 7 arranged on the first side surface 1a, ensuring heat exchange efficiency even in concentrated arrangement. Furthermore, the base leg 3 supporting the housing 1 can be made as large as possible in the width direction. This allows the outdoor unit 100 of the refrigeration cycle apparatus to be stably arranged outdoors.

[0028] 6 and 9, a wall portion 4f is connected to the y-direction of the narrowed portion 4g of the pillar 4. The wall portion 4f is arranged to close the y-direction end of the heat exchanger 7. This prevents air drawn into the housing 1 from the first side surface 1a from bypassing the heat exchanger 7. The wall portion 4f of the pillar 4 is configured to fix the heat exchanger 7, and the housing 1, including the pillar 4, supports the heat exchanger.

[0029] 9, the throttle portion 4g of the pillar 4 is disposed with a slight difference in level with the wall portion 4f in the x direction, which makes it easier for air to flow into the gap 90 along the pillar 4. Note that the throttle portion 4g and the wall portion 4f can also be configured to be flush with each other.

[0030] 7, the pillar 4 is provided with a drawn portion 4g, which allows the flange portion 22 of the bottom plate 2 to be directly fixed to the drawn portion 4g. The bottom plate 2 and pillar 4 are also fixed by the chamfered portion 4d and the raised piece 24, and are further connected via the second portion 4e and the base leg 3. In this way, the bottom plate 2 and pillar 4 are firmly connected.

[0031] As shown in Fig. 10, the protruding portion 4c of the pillar 4 protrudes in the x direction beyond the narrowed portion 4g and the wall portion 4f. This allows the base leg 3, which is disposed inside the pillar 4, to protrude in the x direction beyond the bottom plate 2, thereby supporting the housing 1 over a wider width, improving the stability of the housing 1. Also, as shown in Fig. 5, the base leg 3 has a pillar fixing portion 35 at its end, which is joined to the chamfered portion 4d of the pillar 4 by a bolt 42. This integrates the base leg 3 and the pillar 4, improving the rigidity and strength of the housing 1.

[0032] As described above, the pillar 4, bottom plate 2 and base leg 3 are integrated at the corners of the base 20 using bolts 40 to 43, thereby ensuring the strength and rigidity of the housing 1 while keeping the air inflow path wide by the narrowed portion 4g of the pillar 4, and ensuring a sufficient amount of air inflow to the heat exchanger 7 at the bottom of the housing 1.

[0033] 11A and 11B are schematic diagrams of a gap 90 when the outdoor unit 100 of the refrigeration cycle apparatus according to the first embodiment and the outdoor unit 1000 of the refrigeration cycle apparatus according to the comparative example are respectively arranged in a concentrated manner. FIG. 11A shows the gap 90 when the outdoor unit 1000 of the refrigeration cycle apparatus according to the comparative example is arranged in a concentrated manner, and FIG. 11B shows the gap 90 when the outdoor unit 1000 of the refrigeration cycle apparatus according to the first embodiment is arranged in a concentrated manner. The first side surface 1a of the outdoor units 1000A and 1000B of the refrigeration cycle apparatus according to the comparative example is configured to be substantially flush over the portion where the base leg 3, the bottom plate 2, and the heat exchanger 7 are arranged, and in particular, the width dimension W1 between the flange portions 22 of the bottom plate 2 is substantially the same as the width dimension W between the base legs 3.

[0034] On the other hand, when the outdoor units 100 of the refrigeration cycle device of embodiment 1 are centrally arranged, the flange portions 22 of the bottom plate 2 are recessed toward the heat exchanger 7 from the ends of the base legs 3, and the width dimension W2 between the flange portions 22 of the bottom plate 2 is larger than the width dimension W between the base legs 3.

[0035] In the first embodiment, the narrowed portions 4g of the pillars 4 are joined to the flange portions 22 of the bottom plate 2 by bolts 43. Therefore, the distance between the narrowed portions 4g of the pillars 4 that form the corners of the housings 1 of the outdoor units 100A and 100B of the refrigeration cycle devices that are arranged next to each other is also approximately the same as the width dimension W2 between the flange portions 22 of the bottom plate 2, which contributes to increasing the opening area of ​​the gap 90.

[0036] By providing the tapered portion 4g and the protruding portion 4c of the pillar 4, an inclined portion 4b is formed in the first portion 4a of the pillar 4. In this way, a step shape is formed in the lower end of the pillar 4, and the base 20 of the housing 1 is joined to the flange portion 22 of the bottom plate 2 in the vicinity thereof, thereby improving the strength and rigidity of the base 20.

[0037] Although the outdoor unit 100 of the refrigeration cycle apparatus has been described above based on the embodiment, the outdoor unit 100 of the refrigeration cycle apparatus is not limited to the configuration of the above-described embodiment. The configuration of the outdoor unit 100 of the refrigeration cycle apparatus described above is an example, and other components may be included, or some components may be omitted. In short, the outdoor unit 100 of the refrigeration cycle apparatus includes the range of design changes and application variations that are normally made by a person skilled in the art, as long as they do not deviate from the technical concept thereof.
