Description

Technical Field

[0001] This disclosure relates to the outdoor unit of a refrigeration cycle system installed outdoors. Background Technology

[0002] Previously, outdoor units, which are part of a refrigeration cycle device such as an air conditioner, were known and installed outdoors. The outdoor unit of an air conditioner disclosed in Patent Document 1 includes: a generally rectangular box-shaped housing, a fan, and components comprising a refrigerant circuit including a compressor and a heat exchanger. The housing includes: a base supporting the compressor, a frame supporting the propeller fan, and a support column supporting the heat exchanger. The support column has a wall for fixing the heat exchanger and a structure that prevents air from passing through any part other than the heat exchanger when air is drawn in. Furthermore, the base is fixed to the support column and covers the area below the heat exchanger to also allow for the drainage of water from the heat exchanger.

[0003] Patent Document 1: International Publication No. 2018 / 011939

[0004] Regarding the outdoor unit of the air conditioner disclosed in Patent Document 1, there is limited airflow from the base covering the bottom of the heat exchanger towards the lower part of the heat exchanger. In particular, in the case of air conditioners installed in buildings or similar locations, multiple outdoor units need to be concentrated in a small area such as a rooftop. To reduce the installation area, the gaps between the casings cannot be large, and the spacing between adjacent outdoor units becomes narrower. Although air flows into the gap between the two outdoor units through the heat exchanger positioned facing the gap between them, there is a problem that the amount of air flowing into the lower part of the heat exchanger, located near the installation surface, is limited due to the base covering the bottom of the heat exchanger. Utility Model Content

[0005] This disclosure was made to solve the problems described above, and its object is to provide an outdoor unit of a refrigeration cycle device that can ensure airflow to the portion of the heat exchanger located in the lower part of the housing even in a centralized configuration.

[0006] The outdoor unit of the refrigeration cycle apparatus disclosed herein includes: a housing formed in a rectangular parallelepiped shape; a heat exchanger housed inside the housing and disposed along a first open side of the housing; and a fan disposed on the upper part of the housing to exhaust air that has passed through the heat exchanger from the upper surface of the housing. The housing, at least from its bottom surface to the area housing the heat exchanger, has a shape in which adjacent sides of the housing are connected by inclined surfaces. The outdoor unit of the refrigeration cycle apparatus further includes: a base forming the bottom surface of the housing and supporting legs; and a plurality of pillars engaging with the corners of the base and extending in the height direction of the housing. At least one of the multiple support pillars disposed at the end of the first side has its lower end joined to the base and includes: a first portion having a surface parallel to the first side and located at the end of the first side in the width direction; a second portion having a surface parallel to a second side adjacent to the first side and located at the end of the second side in the width direction; and a chamfered portion disposed between the first portion and the second portion, having the inclined surface. The first portion includes: a protrusion formed at the lower end; and a constriction portion located above the protrusion. The constriction portion is located in a direction perpendicular to the first side and positioned closer to the heat exchanger side than the protrusion.

[0007] Additionally, the base includes: a base leg supporting the housing; a base plate fixed to the base leg to form the bottom surface of the housing; and a drain pan fixed to the base plate and disposed at least below the heat exchanger. The base leg protrudes in a direction perpendicular to the first side from the contraction of the base plate and the support column, and the support column engages with the base leg at its lower end.

[0008] In addition, when viewed from above, the ends of the base legs are shaped along the lower end of the first part of the support, the chamfered part, and the second part, and overlap with the support to join them.

[0009] In addition, the base plate has an upward-facing flange at the end, and the constricted portion of the support column is joined to the flange.

[0010] In addition, the first part has an inclined portion that connects the contraction portion and the protrusion portion, and is joined to the base plate above the inclined portion.

[0011] According to this disclosure, by providing a contraction section in the support column, airflow to the portion of the heat exchanger located in the lower part of the casing can be ensured even when the outdoor unit of the refrigeration cycle device is centrally configured.

Detailed Implementation

[0023] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Furthermore, identical or equivalent parts are labeled with the same reference numerals in each drawing, and their descriptions are appropriately omitted or simplified. Additionally, the shape, size, and arrangement of the structures depicted in each drawing can be appropriately modified.

[0024] Implementation Method 1

[0025] Figure 1 This is a perspective view showing the appearance of the outdoor unit 100 of the refrigeration cycle device according to Embodiment 1. Figure 2 This is a side view of the case where the outdoor units 100 of the refrigeration cycle device according to Embodiment 1 are centrally arranged.

[0026] like Figure 1and Figure 2 As shown, the outdoor unit 100 of the refrigeration cycle device of Embodiment 1 includes: a longitudinally arranged, generally rectangular box-shaped housing 1; a heat exchanger 7 disposed along the side of the housing 1; and internal components constituting the refrigeration cycle, such as a compressor (not shown), a blower fan 81, a liquid receiver (not shown), and refrigerant piping (not shown), disposed inside the housing 1.

[0027] The housing 1 is generally rectangular and includes: a heat exchanger 7 disposed along a first open side 1a of the housing 1; and a fan 81 disposed at the upper part of the housing 1 to exhaust air that has passed through the heat exchanger 7. The housing 1 has a shape in the z-direction, at least from the bottom surface of the housing 1 to the area housing the heat exchanger 7, where adjacent side surfaces 1a and 1b of the housing 1 are connected by inclined surfaces 1c. In the housing 1 shown in Embodiment 1, inclined surfaces 1c are provided at the corners from the bottom surface to the top surface of the cube.

[0028] Figure 3 This is a perspective view of the housing 1 according to Embodiment 1. The housing 1 includes: a base 20; four support columns 4 extending upward (in the z-direction) from the corners of the base 20; a front panel 5 covering the sides; and a fan housing 6 disposed around the blower fan 81. Furthermore, the base 20, forming the bottom of the housing 1, includes: a base plate 2; base legs 3 supporting the housing 1; and a drain tray 8. The four support columns 4 are connected at the upper part of the housing 1 via the fan housing 6. Figure 3 The structure shown is an example where the four pillars 4 can be connected by a frame, including the fan housing 6. Additionally, the two pillars 4 located at either end of the width direction of the second side 1b of the housing 1 are connected by the front panel 5. Thus, it is also possible for only a portion of the four pillars 4 to be connected by a frame.

[0029] Figure 4 This is a perspective view of the base plate 2 of the housing 1 according to Embodiment 1. Figure 3 and Figure 4As shown, the base plate 2 is generally rectangular and forms the bottom surface of the housing 1. The two ends extending from the mountain 2a and valley 2b of the base plate 2 are supported and mounted on a pair of base legs 3, located at a predetermined height from the mounting surface 91. Internal components such as a compressor (not shown) are mounted on the upper surface of the base plate 2. The bottom surface of the base plate 2 is formed by bending in a square wave shape where the mountain 2a and valley 2b are alternately connected. The upper surface of the mountain 2a and the bottom surface of the valley 2b are both flat surfaces, formed to be approximately parallel. That is, the cross-sectional shape of the bottom surface of the base plate 2 can also be rectangular wave, trapezoidal wave, or other wave shapes. By making the bottom surface of the base plate 2 wave-shaped, its rigidity increases when a bending moment is applied in the planar direction, thus improving its strength. Furthermore, the base plate 2 has flanges 22 formed by bending upwards at both ends in the direction (x-direction) where the mountain 2a and valley 2b are alternately connected.

[0030] Additionally, the base plate 2 has drainage holes for discharging the drain water generated by the heat exchanger 7 and flowing to the bottom surface of the base plate 2 to the outside. A drain pan 8 (see reference) is mounted on the upper surface of the base plate 2. Figure 6 The drain pan 8 is located below the heat exchanger 7.

[0031] Figure 5 This is a perspective view of the base leg 3 of the housing 1 according to Embodiment 1. Figure 3 As shown, the base leg 3 is positioned below the base plate 2, supporting the base plate 2. The base leg 3 is formed, for example, by bending a steel plate, and extends along the direction (x direction) where the mountain 2a and valley 2b of the base plate 2 alternately connect. The base leg 3 protrudes in the x direction relative to the base plate 2.

[0032] The base leg 3 has: a planar mounting portion 30 disposed on the mounting surface of the outdoor unit 100 of the refrigeration cycle device; an upright portion 31 that rises upward from one end edge of the mounting portion 30 along the length direction (x direction); a support portion 32 that bends horizontally from the upper end edge of the upright portion 31 along the length direction (x direction); and a wall portion 33 that rises upward from the front end edge of the support portion 32 along the length direction (x direction). The base leg 3 is formed by the mounting portion 30, the upright portion 31, and the support portion 32 in a roughly C-shaped longitudinal section. The horizontal direction is a general concept and does not need to be strictly horizontal.

[0033] The support portion 32 is used to mount the ends of the mountain portion 2a and valley portion 2b of the base plate 2. The lower surface of the valley portion 2b of the base plate 2 abuts against the upper surface of the support portion 32. A positioning mechanism is formed on the base plate 2 and the support portion 32 to position the base plate 2 and the support portion 32 when the base plate 2 is mounted on the support portion 32. The positioning mechanism has: a first embossment 21 formed at both ends of the valley portion 2b mounted on the base leg 3; and a second embossment 34 formed on the support portion 32. The first embossment 21 is formed to protrude upward from the upper surface of the valley portion 2b. Multiple first embossments 21 are formed at intervals along the direction of the wave. Multiple second embossments 34 are formed to protrude upward from the upper surface of the support portion 32. Multiple second embossments 34 are formed along the length direction of the support portion 32. The first embossment 21 and the second embossment 34 engage with each other when the base plate 2 is mounted on the support portion 32. With the first protrusion 21 and the second protrusion 34 already engaged, they are joined from the lower surface of the base plate 2 by screws or other connecting components. The head of the connecting component is housed within the recess of the second protrusion 34. The outdoor unit 100 of the refrigeration cycle device, equipped with a positioning mechanism, can easily position the base plate 2 in a predetermined location. Furthermore, the position and number of the first protrusion 21 and the second protrusion 34 are not limited to the structure shown in the figure, and can be appropriately varied depending on the installation location of the outdoor unit 100 of the refrigeration cycle device or the shape and size of the base plate 2.

[0034] The wall portion 33 is formed such that its wall surface faces the end of the base plate 2, which is mounted on the support portion 32. For example... Figure 3 As shown, the wall portion 33 is formed to be almost the same height as the flange portion 22 of the base plate 2, and is configured to surround the base 20 that forms the bottom surface of the housing 1 together with the flange portion 22.

[0035] Support column fixing portions 35 are formed at both ends of the base leg 3 in the x-direction. The ends of the base leg 3 are obliquely cut according to the shape of the inclined surface 1c of the housing 1, forming a chamfered portion 4d along the support column 4 constituting the inclined surface 1d. The support column fixing portions 35 overlap with the chamfered portion 4d of the support column 4 and are secured by bolts 42 (see reference). Figure 6 It is joined to the lower end of the support column 4.

[0036] Figure 6 yes Figure 1 An enlarged perspective view of part A of the outdoor unit 100 of the refrigeration cycle device. Figure 7 This is a perspective view of the corner of the base 20 according to Embodiment 1, viewed from the inside. Figure 8This is a perspective view of the support column 4 of the housing 1 according to Embodiment 1. The base plate 2 has a stand-up piece 24 at the corner, which is joined to the support column 4 by bolts 41. In addition, the base leg 3 and the support column 4 are joined by bolts 40. Furthermore, the lower end of the front panel 5 covering the second side 1b of the housing 1 is also fixed to the base leg 3 by bolts 44.

[0037] (Pillar 4)

[0038] The support pillars 4 are fixed to the base 20, forming the four corners of the housing 1. The four support pillars 4 are connected at the lower end of the housing 1 via the base 20 and at the upper end of the housing 1 via the fan housing 6, forming a roughly rectangular shape of the housing 1.

[0039] The support column 4 includes: a first portion 4a, forming the end portion of the first side surface 1a of the housing 1 in the width direction (y direction); a second portion 4e, forming the end portion of the second side surface 1b in the width direction (x direction); and a chamfered portion 4d connecting the first portion 4a and the second portion 4e. The first portion 4a of the support column 4 is composed of a protrusion 4c, an inclined portion 4b, and a constricted portion 4g from bottom to top. The lower end of the first portion 4a of the support column 4 is formed along the shape of the end of the base leg 3, and a protrusion 4c is formed protruding in a direction perpendicular to the first side surface 1a of the housing 1 (x direction). A constricted portion 4g is formed above the protrusion 4c, and the constricted portion 4g is located closer to the heat exchanger 7 than the protrusion 4c. The constricted portion 4g is engaged with the flange portion 22 of the base plate 2 by bolts 43. The protrusion 4c and the constricted portion 4g are connected by the inclined portion 4b to ensure the strength and rigidity of the support column 4. Furthermore, the second portion 4e of the support column 4 is engaged with the wall portion 33 of the base leg 3 by bolts 40. Thus, the support column 4 is bolted to the base plate 2 and base leg 3 forming the base 20, forming the main frame of the housing 1. Furthermore, the shape of the lower end of the support column 4 follows the shape of the end of the base leg 3 when viewed from above, and the protrusion 4c of the support column 4 follows... Figure 5 The end face 36 of the base leg 3 shown is configured, the chamfered portion 4d is configured along the support fixing portion 35, and the second portion 4e is configured along the surface of the wall portion 33.

[0040] Figure 9 yes Figure 2 A diagram illustrating the B-B cross-section. Air flows towards the heat exchanger 7 through the gap 90 between the outdoor units 100 of the two refrigeration cycle units. The gap 90 is the space formed by the first side 1a of the two outdoor units 100 of the refrigeration cycle units facing each other. Air flows in from the second side 1b. Figure 9In the cross-section, the support column 4 has a chamfered portion 4d, and the air inlet is wide, gradually narrowing towards the heat exchanger 7, so that air can easily flow in. The chamfered portion 4d is a part that constitutes the inclined surface 1c of the housing 1, and is equivalent to the chamfered shape provided at the corner from the bottom surface to the top surface of the housing 1.

[0041] Figure 10 yes Figure 2 An enlarged view of section C. For the portion of the gap 90 closest to the mounting surface 91, airflow tends to decrease due to the influence of the mounting surface 91. In particular, as... Figure 2 In the case of the outdoor unit 100 with the refrigeration cycle unit centrally configured as shown, the dimensions between the housings 1 are set small in order to reduce the installation area. However, for the first part 4a of the support column 4, a protrusion 4c is provided at the lower end to sufficiently ensure the width dimension of the base leg 3 in the x direction, and a contraction part 4g is provided above the base leg 3 and the base plate 2 to sufficiently ensure the width dimension W2 of the gap 90. As a result, even at the lower part of the heat exchanger 7, which is easily affected by the installation surface 91, the amount of air flowing in can be sufficiently ensured.

[0042] Typically, in the case of centralized installation, the spacing of the housing 1 is set based on the width W of the gap between the parts where the base legs 3 are provided. For example, the width W of the gap between the parts where the base legs 3 are provided is set to 30 mm. Then, the width W2 of the gap of the contraction part 4g is set to be larger than 30 mm. As a result, for the outdoor unit 100 of the refrigeration cycle device, air can easily flow into the air intake of the first side 1a where the heat exchanger 7 is provided.

[0043] In addition, such as Figure 7 As shown, the lower end of the constricted portion 4g of the support column 4 is fixed to the end of the flange portion 22 of the base plate 2. Therefore, the drain pan 8 fixed to the base plate 2 can be positioned as close as possible to the constricted portion 4g of the support column 4 in the x-direction. Simultaneously, the constricted portion 4g of the support column 4 is positioned near the heat exchanger 7 in the x-direction. With this configuration, the outdoor unit 100 of the refrigeration cycle device according to Embodiment 1 has a larger gap 90 for supplying air to the heat exchanger 7 located on the first side 1a, ensuring heat exchange efficiency even in a centralized configuration. Furthermore, the base legs 3 of the support housing 1 can be as large as possible in the width direction. Therefore, the outdoor unit 100 of the refrigeration cycle device can be stably configured even outdoors.

[0044] like Figure 6 and Figure 9As shown, a wall portion 4f is connected to the constricted portion 4g of the support column 4 in the y-direction. The wall portion 4f is configured to block the end of the heat exchanger 7 in the y-direction. This prevents air drawn into the housing 1 from the first side 1a from bypassing the heat exchanger 7. In addition, the wall portion 4f of the support column 4 is configured to fix the heat exchanger 7, such that the housing 1 including the support column 4 supports the heat exchanger.

[0045] like Figure 9 As shown, the contraction portion 4g of the support column 4 is configured to have a slight step difference with the wall portion 4f in the x-direction. This allows air to easily flow into the gap 90 along the support column 4. Furthermore, the contraction portion 4g and the wall portion 4f can also be configured to be coplanar.

[0046] In addition, such as Figure 7 As shown, by providing a contraction portion 4g to the support column 4, the flange portion 22 of the base plate 2 can be directly fixed to the contraction portion 4g. Furthermore, the base plate 2 and the support column 4 are fixed by the chamfered portion 4d and the upright piece 24, and connected via the second part 4e and the base leg 3. In this way, the base plate 2 and the support column 4 are securely connected.

[0047] like Figure 10 As shown, the protrusion 4c of the support column 4 protrudes further in the x-direction than the contraction 4g and the wall portion 4f. Therefore, the base leg 3, located inside the support column 4, can protrude further in the x-direction than the base plate 2, allowing for wider support of the housing 1, thus improving the stability of the housing 1. Furthermore, as... Figure 5 As shown, the base leg 3 has a support fixing part 35 at its end, which is engaged with the chamfered part 4d of the support column 4 by bolts 42. Thus, the base leg 3 and the support column 4 become a single unit, and the rigidity and strength of the housing 1 are improved.

[0048] As described above, the support column 4, base plate 2, and base leg 3 are integrated at the corner of the base 20 using bolts 40-43, thus ensuring the strength and rigidity of the housing 1. Furthermore, the narrow section 4g of the support column 4 maintains a wide airflow path, ensuring sufficient airflow to the heat exchanger 7 at the lower part of the housing 1.

[0049] Figure 11 (a) and (b) are schematic diagrams of the gap 90 when the outdoor unit 100 of the refrigeration cycle device according to Embodiment 1 and the outdoor unit 1000 of the refrigeration cycle device according to the comparative example are respectively arranged in a concentrated manner. Figure 11 (a) shows the gap 90 in the case where the outdoor unit 1000 of the refrigeration cycle unit involved in the comparative example is centrally arranged. Figure 11(b) shows the gap 90 when the outdoor units 100 of the refrigeration cycle device according to Embodiment 1 are arranged in a concentrated manner. The first side 1a of the outdoor units 1000A and 1000B of the refrigeration cycle device according to the comparative example are generally coplanar in the portion where the base legs 3, the base plate 2 and the heat exchanger 7 are arranged throughout. In particular, the width dimension W1 between the flanges 22 of the base plate 2 is almost the same as the width dimension W between the base legs 3.

[0050] On the other hand, when the outdoor units 100 of the refrigeration cycle device according to Embodiment 1 are arranged in a concentrated manner, the flange portion 22 of the base plate 2 is configured to be retracted towards the heat exchanger 7 than the end of the base leg 3, and the width dimension W2 between the flange portions 22 of the base plate 2 is larger than the width dimension W between the base legs 3.

[0051] In embodiment 1, the concave portion 4g of the support column 4 is joined to the flange portion 22 of the base plate 2 by bolts 43. Therefore, the spacing between the concave portions 4g of the support columns 4 at the corners of the housings 1 of the outdoor units 100A and 100B that constitute adjacent refrigeration cycle devices is almost the same as the width W2 between the flange portions 22 of the base plate 2, which helps to increase the opening area of ​​the gap 90.

[0052] By providing a constricted portion 4g and a protruding portion 4c to the support column 4, an inclined portion 4b is formed in the first part 4a of the support column 4. In this way, a stepped shape is formed at the lower end of the support column 4, which engages with the flange portion 22 of the base plate 2 nearby, thus improving the strength and rigidity of the base 20 of the housing 1.

[0053] The outdoor unit 100 of the refrigeration cycle device has been described above based on the embodiments, but the outdoor unit 100 of the refrigeration cycle device is not limited to the structure of the above embodiments. The structure of the outdoor unit 100 of the refrigeration cycle device described above is an example, and may include other constituent elements, and some constituent elements may be omitted. In short, the outdoor unit 100 of the refrigeration cycle device includes the range of design changes and application variations that can be generally made by those skilled in the art without departing from its technical concept.
