DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the idea for the present disclosure, the technology for outdoor units of air conditioners was such that it was common for outdoor units to be equipped with metallic fan guards and finger guards. For this reason, in the industry, it was common to design products by painting metal fan guards and finger guards, as these are susceptible to corrosion such as rust. Under these circumstances, the inventors were inspired by the fact that painting requires labor and costs, and came up with the idea of using a material that does not require painting. The inventors then discovered that to realize this idea, if both the fan guard and the finger guard were made of resin, there would be an issue that the strength of the fan guard would be insufficient, and they came up with the subject matter of the present disclosure in order to solve this issue.
[0009] In view of this, the present disclosure provides an outdoor unit that has a simple configuration and sufficient durability.
[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed description than necessary may be omitted. For example, detailed description of already well-known matters or duplicate description of substantially the same configuration may be omitted. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.
[0011] (Embodiment 1) [1-1. Configuration] Hereinafter, the first embodiment will be described with reference to Figures 1 to 5. Note that the arrows marked with the symbols FR, UP, and LH in the figures correspond to the forward, upward, and leftward directions in the text, respectively, and the directions such as forward, backward, upward, downward, left, and right in the text are based on these unless otherwise specified. Also, for convenience of explanation, the drawings of members overlapping the main parts and parts that are more detailed than necessary may be omitted in the figures.
[0012] Fig. 1 is a perspective view of an outdoor unit 1 according to the first embodiment. The outdoor unit 1 is an outdoor unit of an air conditioner, and forms a refrigeration cycle circuit by being connected to an indoor unit (not shown) via refrigerant piping (not shown). The outdoor unit 1 includes a blower 14, a heat exchanger 16, etc. inside a housing 10, and is installed on an installation surface via a pair of legs 18. The legs 18 are bases for the housing 10, and are aligned in the left-right direction to support the housing 10 from below.
[0013] The outdoor unit 1 includes a housing 10 having a substantially rectangular parallelepiped shape. The housing 10 is divided into a blower room 10a and a machine room 10b by a partition plate 12. The blower room 10a is a space divided on the right side of the housing 10. Inside the blower room 10a, a blower 14, a heat exchanger 16, and the like are provided. The blower 14 is an axial flow fan, and when driven, it blows air forward. The heat exchanger 16 is, for example, a fin-tube type heat exchanger. The heat exchanger 16 functions as an evaporator or condenser by being connected to an indoor unit (not shown) via a refrigerant pipe (not shown). The heat exchanger 16 includes a large number of fins (not shown) and exchanges heat between the air flowing between the fins and the refrigerant inside. The heat exchanger 16 is provided so as to cover the rear and right side of the blower room 10a.
[0014] The machine chamber 10b is a space partitioned on the left side of the housing 10 by a partition plate 12, and contains a compressor, an accumulator, a control board for the outdoor unit 1, and the like (not shown). The machine chamber 10b communicates with the fan chamber 10a through a duct (not shown) provided in the partition plate 12.
[0015] The housing 10 has a top panel 11a on the top surface 11, and a first front panel 13a and a second front panel 13b on the front surface 13 (second side surface). The top panel 11a is a plate-like member formed by bonding together a metal plate exposed on the outside of the housing 10 and a heat insulating material facing the inside of the housing 10. The top panel 11a covers the entire top surface 11.
[0016] The first front panel 13a is a plate-like member that covers the right side of the front surface 13, i.e., the front of the blower chamber 10a, and is made of sheet metal. The first front panel 13a is a part of the housing 10. The first front panel 13a has an air outlet 13c that is a hole that opens in a substantially circular shape in the center. The air outlet 13c communicates between the blower chamber 10a and the outside of the housing 10. The air outlet 13c opens in front of the blower 14. Therefore, the air that is blown forward by the drive of the blower 14 is blown out to the outside of the housing 10 through the air outlet 13c. That is, the blower 14 blows air to the outside of the housing 10 through the air outlet 13c.
[0017] The air outlet 13c is covered from the front by the fan guard 30. The fan guard 30 is a metal plate-like member with a large number of holes arranged in a staggered pattern, and its surface is painted. The metal used to form the fan guard 30 is, for example, steel, stainless steel, aluminum, aluminum alloy, copper, copper alloy, etc. The fan guard 30 is substantially rectangular in side view from the front, and is fixed to the first front panel 13a by screwing. The air blown forward from the air outlet 13c by the driving of the blower 14 flows forward of the fan guard 30 through the large number of holes provided in the fan guard 30. That is, the fan guard 30 is capable of ventilation. The large number of holes formed in the fan guard 30 are each large enough that a person's finger cannot be inserted. Therefore, the fan guard 30 can prevent a person from accidentally touching the blower 14 while it is running. The total area of all the holes in the fan guard 30 is large enough that the air blown from the blower 14 can flow sufficiently. This reduces the pressure loss of the air sent out from the blower 14 due to the fan guard 30. Note that if the total area of all the holes in the fan guard 30 is increased, the strength of the fan guard 30 itself will decrease. For this reason, the outdoor unit 1 uses metals such as steel, which have high strength, as materials, to ensure the strength of the fan guard 30.
[0018] The second front panel 13b is a plate-like member that covers the left side of the front surface 13, that is, the front of the machine chamber 10b, and is made of sheet metal. The second front panel 13b is a part of the housing 10.
[0019] A first housing side handle 31 (housing side handle) is provided on the first front panel 13a. The first housing side handle 31 is recessed rearward from the first front panel 13a. Similarly, a second housing side handle 33 (housing side handle) is provided on the second front panel 13b. The second housing side handle 33 is recessed rearward from the second front panel 13b. When an operator lifts the outdoor unit 1, the operator can place his or her hands on the first housing side handle 31 and the second housing side handle 33.
[0020] FIG. 2 is a side view of the outdoor unit 1, showing the outdoor unit 1 as viewed from the right side. An intake port 15a that opens to the right is formed on the right side surface 15 (first side surface) of the housing 10. The intake port 15a is surrounded on all four sides by a metal rear panel 17a that covers the rear surface 17 of the housing 10, a bottom panel 19a that covers the bottom surface 19, a first front panel 13a, and a top panel 11a. The rear panel 17a is a part of the housing 10. The intake port 15a communicates with the blower chamber 10a and the outside of the housing 10. A heat exchanger 16 is adjacent to the intake port 15a, and the heat exchanger 16 covers almost the entire surface of the intake port 15a from the inside of the blower chamber 10a. Therefore, air outside the housing 10 flows into the blower chamber 10a through the intake port 15a by the drive of the blower 14, and passes between the many fins of the heat exchanger 16. As a result, the air that has flowed into the blower chamber 10a exchanges heat with the refrigerant flowing inside the heat exchanger 16. The air that has exchanged heat with the refrigerant is sent forward by the blower 14 and blown out to the outside of the housing 10 through the outlet 13c. That is, by driving the blower 14, the air outside the housing 10 flows sequentially through the suction port 15a, the heat exchanger 16, the blower 14, and the outlet 13c, and is blown out to the outside of the housing 10 again.
[0021] The suction port 15a is covered from the right side by a resin finger guard 50. Since the finger guard 50 is made of resin, it does not require painting to prevent rust, and it is easy to mold. The finger guard 50 may be made of a thermoplastic resin such as polyethylene, polystyrene, polyvinyl chloride, or polypropylene, or may be made of a thermosetting resin such as melamine resin, phenol resin, or urea resin.
[0022] The finger guard 50 is integrally formed in a lattice shape with a plurality of vertical guards 51 (guards) extending in the vertical direction and a plurality of horizontal guards 53 (guards) extending in the front-rear direction. The vertical guards 51 and the horizontal guards 53 are each a long, thin, straight bar-shaped portion of the finger guard 50. Both ends of the plurality of vertical guards 51 and the plurality of horizontal guards 53 are connected to a frame portion 59. The frame portion 59 is an outer frame of the finger guard 50, and is a frame-shaped portion that surrounds the outside of the finger guard 50 in a substantially rectangular shape in a side view from the right side. The frame portion 59 overlaps the first front panel 13a and the rear panel 17a in a side view from the right side. The plurality of vertical guards 51 are disposed with a first interval D1 between them in the front-rear direction. The plurality of horizontal guards 53 are disposed with a second interval D2 between them in the vertical direction. Therefore, in the finger guard 50, ventilation is possible in the left-right direction between the vertical guards 51 and between the horizontal guards 53. Therefore, when the blower 14 is driven, air outside the housing 10 passes through the finger guard 50 and flows from the suction port 15a into the blower chamber 10a.
[0023] FIG. 3 is a perspective view of the main part of the finger guard 50, showing the upper part of the finger guard 50. As shown in FIG. 3, the frame part 59 is disposed at a third distance D3 in the left-right direction from the first front panel 13a and the rear panel 17a. This third distance D3 is large enough that the frame part 59 does not hit the first front panel 13a and the rear panel 17a when the finger guard 50 vibrates as described later. As shown in FIG. 2 and FIG. 3, the frame part 59 is formed with a plurality of fixing parts 59a. The plurality of fixing parts 59a are screwed to the first front panel 13a and the rear panel 17a. This allows the finger guard 50 to be easily attached and detached to the housing 10. As shown in FIG. 3, the plurality of fixing parts 59a contact the first front panel 13a and the rear panel 17a, which are parts of the housing 10, respectively.
[0024] Moreover, among the side guards 53, the side guards 53 connected to the fixed portion 59a are thicker than the side guards 53 not connected to the fixed portion 59a. Specifically, the vertical width W1 of the side guards 53 connected to the fixed portion 59a is larger than the vertical width W2 of the side guards 53 not connected to the fixed portion 59a. As a result, the finger guard 50 has the wide and rigid side guards 53 directly connected to the housing 10. Therefore, compared to a case in which the thicknesses of all the side guards 53 are uniform, the strength of the finger guard 50 can be efficiently increased while suppressing the projected area of the finger guard 50 in a side view from the right direction.
[0025] FIG. 4 is a perspective view of the main part of the finger guard 50, showing the lower part of the finger guard 50. A handle 55 is formed at the rear part of the lower part of the finger guard 50. The handle 55 is recessed to the left and is connected to the frame part 59 and the vertical guard 51. The handle 55 is also connected to the vertical reinforcement guard 52 (reinforcement guard) and the horizontal reinforcement guard 54 (reinforcement guard). The vertical reinforcement guard 52 and the horizontal reinforcement guard 54 are rod-shaped parts extending vertically or in the front-rear direction. The vertical reinforcement guard 52 is disposed at a distance narrower than the first distance D1 from the vertical guard 51. The horizontal reinforcement guard 54 is disposed at a distance narrower than the second distance D2 from the horizontal guard 53. In this way, the vertical reinforcement guard 52 and the horizontal reinforcement guard 54 are densely disposed around the handle 55 in addition to the vertical guard 51 and the horizontal guard 53. The vertical reinforcement guard 52 and the horizontal reinforcement guard 54 connect the handle 55 to the vertical guard 51 and the horizontal guard 53. This increases the strength of the periphery of the handle 55. The handle 55 is also provided with a plurality of slit holes 55a extending in the vertical direction. The slit holes 55a are formed to penetrate the handle 55. Therefore, air inside the recess of the handle 55 flows from the suction port 15a to the blower chamber 10a through the slit holes 55a.
[0026] Moreover, the handle 55 is formed at approximately the same height as the first housing handle 31 provided on the front surface 13 in the height direction.
[0027] [1-2. Action, action] The operation and function of the outdoor unit 1 configured as above will now be described.
[0028] [1-2-1. Operation during driving] When an air conditioner including the outdoor unit 1 performs cooling or heating operation, the outdoor unit 1 drives the blower 14 to exchange heat between the refrigerant in the heat exchanger 16 and the air outside the housing 10. At this time, the air outside the housing 10 passes through the finger guard 50 and the intake port 15a from right to left in this order, and flows into the blower chamber 10a.
[0029] At this time, the smaller the projected area of the finger guard 50 when the housing 10 is viewed from the right, the smaller the pressure loss when the air passes through the finger guard 50 from right to left. In the first embodiment, the strength of the finger guard 50 is increased by making only the width W1 of the side guard 53 connected to the fixing part 59a larger than the width W2 of the other side guards 53. Therefore, the projected area of the finger guard 50 when the housing 10 is viewed from the right is smaller than the projected area when all the side guards 53 are configured to have the width W1. Therefore, the pressure loss when the air passes through the finger guard 50 from right to left is suppressed, and the flow rate of the air flowing into the blower chamber 10a is increased.
[0030] Furthermore, the handle 55 of the finger guard 50 is provided with a plurality of slits 55a. Therefore, air flows from right to left through the slits 55a, increasing the flow rate of air flowing into the fan chamber 10a.
[0031] In the present embodiment, the frame 59 is provided with a gap of the third distance D3 between the first front panel 13a and the rear panel 17a. Therefore, air can pass through this gap, and the flow rate of air flowing into the fan chamber 10a increases.
[0032] The finger guard 50 may vibrate due to air passing through the finger guard 50, which may cause the frame 59 to vibrate. At this time, if the frame 59 hits the first front panel 13a and the rear panel 17a, noise is generated. In this embodiment, the fixing part 59a is fixed in contact with the first front panel 13a and the rear panel 17a, so it does not vibrate. In addition, the frame 59 is provided between the first front panel 13a and the rear panel 17a with a gap of the third distance D3, so it does not hit the first front panel 13a and the rear panel 17a. Therefore, the generation of noise when the finger guard 50 vibrates is suppressed.
[0033] The air that has flowed into the blower chamber 10a flows between the multiple fins of the heat exchanger 16, exchanges heat with the refrigerant, and is sent forward by the blower 14. The air sent forward from the blower 14 is blown out of the housing 10 through the air outlet 13c. The air blown out of the housing 10 then flows forward through the fan guard 30.
[0034] [1-2-2. Operation of outdoor unit during installation] When a worker transports the outdoor unit 1, the worker can lift the outdoor unit 1 by placing his / her hands on the handle 55 and the first housing side handle 31. At this time, the strength of the finger guard 50 around the handle 55 is increased by the vertical reinforcement guard 52 and the horizontal reinforcement guard 54. Therefore, even if the finger guard 50 is made of resin, when a worker places his / her hands on the handle 55 to lift the outdoor unit 1, the finger guard 50 is prevented from being damaged by the weight of the outdoor unit 1.
[0035] In the present embodiment, the height at which the handle 55 is provided is substantially the same as the height at which the first housing side handle 31 is provided. Therefore, when an operator places his or her hands on the handle 55 and the first housing side handle 31, the outdoor unit 1 is likely to be kept substantially horizontal, making it easy to lift the outdoor unit 1.
[0036] FIG. 5 is a side view of the outdoor unit 1, showing the housing 10 to which a finger guard 50 different from the finger guard 50 described in FIG. 1 to FIG. 4 is attached, as viewed from the right. The finger guard 50 shown in FIG. 5 has one more handle 55 than the finger guard 50 shown in FIG. 1 to FIG. 4. This handle 55 is formed at a height substantially equal to that of the second housing side handle 33. Since the finger guard 50 is formed of resin, it is possible to create a plurality of patterns of finger guards 50 in which the position of the handle 55 is changed while suppressing costs. Therefore, by preparing a plurality of patterns of finger guards 50 in which the position of the handle 55 is changed, the worker can fix the finger guard 50 suitable for transporting the outdoor unit 1 to the housing 10 according to the situation at the time of construction.
[0037] [1-3. Effects, etc.] As described above, in this embodiment, the outdoor unit 1 comprises a housing 10 with open intake 15a and exhaust 13c, a blower 14 provided inside the housing 10 and blowing air to the outside of the housing 10 via the exhaust 13c, and a heat exchanger 16 provided inside the housing 10 and adjacent to the intake 15a. When the blower 14 is driven, air outside the housing 10 flows sequentially through the intake 15a, the heat exchanger 16, the blower 14, and the exhaust 13c. In this outdoor unit, the exhaust 13c is covered by a fan guard 30 which allows ventilation, and the intake 15a is covered by a finger guard 50 which allows ventilation. The fan guard 30 is made of metal and the finger guard 50 is made of resin.
[0038] According to this configuration, by making the finger guard 50 out of resin, rusting of the finger guard 50 is prevented without painting the finger guard 50. Therefore, with a simple configuration, it is possible to improve the durability of the outdoor unit 1 while suppressing costs. Furthermore, by making the fan guard 30 out of metal, it is possible to ensure safety while smoothing the flow of air by the blower 14. Therefore, the efficiency of heat exchange between the refrigerant and the air in the heat exchanger 16 is improved.
[0039] In addition, in the outdoor unit 1, the finger guard 50 is formed as a single unit with a plurality of elongated vertical guards 51 and horizontal guards 53 arranged in a grid pattern, and the finger guard 50 has fixing portions 59a for fixing to the housing 10, and some of the plurality of vertical guards 51 and horizontal guards 53 are connected to the fixing portions 59a, and the vertical guards 51 and horizontal guards 53 connected to the fixing portions 59a are thicker than the vertical guards 51 and horizontal guards 53 not connected to the fixing portions 59a.
[0040] This configuration makes it possible to efficiently improve the strength of the fingered guard 50 while suppressing the projected area of the fingered guard 50. Therefore, it is possible to suppress the pressure loss caused by the fingered guard 50 for the air flowing into the housing 10 from the suction port 15a. Therefore, it is possible to achieve both durability of the fingered guard 50 and efficiency of heat exchange between the refrigerant and the air in the heat exchanger 16.
[0041] In the outdoor unit 1, the air inlet 15a opens to the right side surface 15 of the housing 10, the finger guard 50 includes a handle 55, and the handle 55 includes a through slit hole 55a.
[0042] This simple configuration makes it easy to lift the outdoor unit 1. In addition, even if the handle 55 is formed on the finger guard 50, the outdoor unit 1 can draw air through the slit holes 55a. This makes it possible to improve the ease of handling of the outdoor unit 1 and to improve the efficiency of heat exchange between the refrigerant and the air in the heat exchanger 16.
[0043] In addition, a first housing side handle 31 and a second housing side handle 33 are provided on the front surface 13 of the housing 10, and the first housing side handle 31 or the second housing side handle 33 and the handle 55 are provided at approximately the same height.
[0044] According to this configuration, when a worker holds the handle 55 and the first housing side handle 31 with his / her hands to lift the outdoor unit 1, the worker can easily lift the outdoor unit 1. Therefore, the ease of installation of the outdoor unit 1 is improved.
[0045] In addition, the finger guard 50 is provided with a vertical reinforcing guard 52 and a horizontal reinforcing guard 54 that connect the handle 55 to the vertical guard 51 and the horizontal guard 53.
[0046] This configuration improves the strength of the finger guard 50 near the handle 55. Therefore, when an operator holds the handle 55 to lift the outdoor unit 1, damage to the finger guard 50 is suppressed.
[0047] The finger guard 50 includes a frame portion 59 that is connected to both ends of the multiple vertical guards 51 and horizontal guards 53 and forms the outer frame of the finger guard 50. The fixing portion 59a is provided on the frame portion 59, and the frame portion 59 is disposed with a space therebetween from the housing 10.
[0048] According to this configuration, the rigidity of the finger guard 50 can be improved by the frame portion 59. In addition, since the frame portion 59 is disposed at a distance from the housing 10, even if the finger guard 50 vibrates due to air flowing through the suction port 15a, the frame portion 59 is prevented from hitting the housing 10. Therefore, noise caused by the finger guard 50 hitting the housing 10 is suppressed.
[0049] (Other embodiments) As described above, the first embodiment has been described as an example of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Therefore, other embodiments will be exemplified below.
[0050] In the first embodiment, it has been described that the vertical width W1 of the side guard 53 connected to the fixed portion 59a is larger than the vertical width W2 of the side guard 53 not connected to the fixed portion 59a. The side guard 53 connected to the fixed portion 59a only needs to have a higher rigidity than the side guard 53 not connected to the fixed portion 59a. Therefore, the horizontal width of the side guard 53 connected to the fixed portion 59a may be configured to be larger than the horizontal width of the side guard 53 not connected to the fixed portion 59a.
[0051] In the first embodiment, it has been described that the first housing handle 31 and the second housing handle 33 are provided on the front side of the housing 10. The first housing handle 31 and the second housing handle 33 may be provided on a side surface of the housing 10. Therefore, the first housing handle 31 and the second housing handle 33 may be provided on the rear surface 17 or on the left side surface of the housing 10.
[0052] In the first embodiment, the outdoor unit 1 is described as being equipped with one blower 14. The number of blowers 14 does not have to be one. Therefore, two or more blowers 14 may be provided.
[0053] In the first embodiment, it has been described that the outdoor unit 1 is installed by being placed on an installation surface via the pair of legs 18. The outdoor unit 1 may also be installed as a wall-mounted unit. [Industrial Applicability]
[0054] The present disclosure is applicable to outdoor units of air conditioners. Specifically, the present disclosure is applicable to outdoor units of home air conditioners and outdoor units of commercial air conditioners. [Explanation of symbols]
