Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners or water heaters, and particularly relates to an outdoor unit, an air conditioner, and a water heater. Background Art

[0002] In a variable-frequency air-conditioning circuit, a reactor mainly plays a dual-filtering role: one is to filter the influence of high-order harmonics from the power grid on the variable-frequency circuit; the other is to filter the influence of high-order harmonics generated by the variable-frequency circuit itself on the power grid. Based on this, the reactor is one of the main components of the variable-frequency air-conditioning circuit. However, when the reactor is in operation, a large amount of heat will be generated due to the flowing current, which is extremely likely to shorten the service life of the reactor. In order not to affect the normal use of other electrical appliances, in the conventional design, the reactor is generally fixed on the air separation baffle of the outdoor unit of the air conditioner. The disadvantage of this installation structure is that the self-weight of the reactor is relatively heavy, and the thickness of the air separation baffle needs to be designed relatively thick, increasing the cost. Summary of the Utility Model

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. The description of at least one exemplary embodiment below is actually only illustrative and in no way restricts the present utility model and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary explanation, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0035] For the convenience of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding explanations are made for the spatial relative descriptions used here.

[0036] In addition, it should be noted that the use of words such as "first", "second", etc. to limit components is only for the convenience of distinguishing the corresponding components. Without additional declaration, the above words have no special meaning. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model.

[0037] Combined with reference to Figures 1 to 8As shown, according to an embodiment of the present utility model, an outdoor unit is provided, which includes a housing, a motor bracket 1, a first reactor box 2, and a first reactor 3. The motor bracket 1, the first reactor box 2, and the first reactor 3 are all located inside the housing, and the first reactor 3 is arranged inside the first reactor box 2. One side of the first reactor box 2 is connected to the housing, and the other side of the first reactor box 2 is connected to the motor bracket 1.

[0038] In this technical solution, when the outdoor unit of the present application is the outdoor unit of an air conditioner, by connecting one side of the first reactor box 2 to the original housing of the outdoor unit and connecting the other side of the first reactor box 2 to the original motor bracket 1 of the outdoor unit, the fixation of the first reactor box 2 is realized. Since the first reactor 3 is installed inside the first reactor box 2, the fixation of the first reactor box 2 is equivalent to the fixation of the first reactor 3. Since the first reactor box 2 and the first reactor 3 therein rely on the housing and the motor bracket 1 to form a reliable support and are no longer assembled on the air separation vertical plate, the air separation vertical plate does not need to be designed with a large thickness to consider the weight bearing of the above two components, so the material cost of the outdoor unit can be reduced. At the same time, the connection of the two sides of the first reactor box 2 to the housing and the motor bracket 1 respectively can also play a role in stabilizing the motor bracket 1. Among them, the motor bracket 1 is made by a sheet metal forming process.

[0039] Referring jointly to Figure 1 、 Figure 2 and Figure 6 As shown, the housing includes a first side plate 5. Taking Figure 1 as a reference, the first side plate 5 is located on the left side. The first reactor box 2 has a first flanging 21 and a second flanging 22. The first flanging 21 is fixed to the top of the first side plate 5 by a first fastener, and the second flanging 22 is fixed to the top of the motor bracket 1 by a second fastener.

[0040] In this embodiment, by fixing the first flanging 21 of the first reactor box 2 to the top of the first side plate 5 and at the same time fixing the second flanging 22 of the first reactor box 2 to the top of the motor bracket 1, it is equivalent to raising the first reactor box 2 to a position close to the top of the housing. If there is accumulated water in the housing, since the installation positions of the first reactor box 2 and the first reactor 3 are relatively high, it can well prevent the accumulated water from entering the first reactor box 2. The housing also includes a top plate 19. The first reactor box 2 is located below the top plate 19, and the top of the first reactor box 2 is very close to the top plate 19. Among them, the first flanging 21 can also just overlap on the top of the first side plate 5, while the second flanging 22 is fixed to the top of the motor bracket 1 by a second fastener, and this can also effectively fix the first reactor box 2 and the first reactor 3.

[0041] Referring jointly to Figure 1 、 Figure 2 andFigure 6 As shown, an outdoor heat exchanger 4 is provided inside the housing. The outdoor heat exchanger 4 includes a first heat exchange part 41. The first heat exchange part 41 is located between the first side plate 5 and the motor bracket 1 and is close to the first side plate 5. The first flanging 21 also overlaps on the top of the first heat exchange part 41.

[0042] In this embodiment, since the first flanging 21 also overlaps on the top of the first heat exchange part 41, this is equivalent to the first heat exchange part 41 also playing a supporting role for the first reactor box 2 and the first reactor 3, so as to share the pressure of the first reactor box 2 and the first reactor 3 on the first side plate 5.

[0043] Combined with reference to Figure 1 、 Figure 6 and Figure 7 As shown, a side air inlet is configured on the first side plate 5. A fan 6 is also provided inside the housing. The fan 6 is fixed on the motor bracket 1. The first reactor box 2 also has a first side wall 23 and a second side wall 24. The first heat exchange part 41 is also located between the first side wall 23 and the first side plate 5. A first ventilation opening 7 is configured on the first side wall 23. The second side wall 24 is located between the first side wall 23 and the motor bracket 1. A second ventilation opening 8 is configured on the second side wall 24.

[0044] In the prior art, the disadvantage of fixing the reactor on the air separation vertical plate of the air conditioner outdoor unit is that: a large amount of heat is generated during the operation of the air conditioner. During the rising process of the heat, it will affect the temperature rise of the reactor. In this application, a first ventilation opening 7 and a second ventilation opening 8 are respectively configured on the first side wall 23 and the second side wall 24 of the first reactor box 2, and the second ventilation opening 8 is in the suction negative pressure area of the fan 6. When the fan 6 operates, the air flow enters from the side air inlet of the first side plate 5, then flows through the first heat exchange part 41, and then flows through the first ventilation opening 7 and the second ventilation opening 8 respectively, so that a convective heat dissipation is formed between the first ventilation opening 7 and the second ventilation opening 8. Tests show that this convective heat dissipation can cool the first reactor 3 by about 28°C, and the cooling effect is remarkable. It can solve the problem of the temperature rise of the reactor, ensure the normal operation of the first reactor 3, and extend the service life of the first reactor 3. Preferably, the number of the first ventilation openings 7 is multiple, and the multiple first ventilation openings 7 are sequentially spaced along the height direction of the first side wall 23. The increase in the number of the first ventilation openings 7 can increase the air volume entering the first reactor box 2, thereby improving the heat dissipation effect.

[0045] Combined with reference to Figure 6 and Figure 7As shown, a shielding portion 9 is provided on the outer surface of the first side wall 23. The width of the shielding portion 9 is greater than the width of the first ventilation opening 7. The shielding portion 9 extends obliquely from above the first ventilation opening 7 to below the first ventilation opening 7, and the distance between the shielding portion 9 and the first side wall 23 gradually increases during the process of extending from above the first ventilation opening 7 to below the first ventilation opening 7.

[0046] In this embodiment, since the first side wall 23 of the first reactor box 2 faces the first side plate 5 of the housing, if rainwater enters the housing through the side air inlet, the rainwater will pass through the fin gaps of the outdoor heat exchanger 4 and drip onto the first side wall 23. And the first ventilation opening 7 is formed in the first side wall 23, so the rainwater is very likely to enter the first reactor box 2 through the first ventilation opening 7, causing potential safety hazards to the first reactor 3. When the shielding portion 9 is provided on the outer surface of the first side wall 23, the shielding portion 9 can block the rainwater, thereby preventing the rainwater from entering the first reactor box 2. At the same time, since the distance between the shielding portion 9 and the first side wall 23 gradually increases during the process of extending from above the first ventilation opening 7 to below the first ventilation opening 7, an opening will be formed between the lower side of the shielding portion 9 and the first side wall 23, and the air flow can still flow through the opening and through the first ventilation opening 7, so as to achieve the effect of preventing rainwater from entering while not affecting the air flow passing through the first ventilation opening 7. It can be understood that when the number of the first ventilation openings 7 is multiple, the number of the shielding portions 9 also increases accordingly.

[0047] Refer to in combination Figure 4 、 Figure 6 and Figure 7 As shown, there is a spacing between the second side wall 24 and the motor bracket 1, denoted as h1, and h1≥1mm. This makes the distance between the second side wall 24 and the motor bracket 1 reasonable, and the motor bracket 1 will not obstruct the air outlet of the second ventilation opening 8. Then the air flow entering from the first ventilation opening 7 can smoothly flow out from the second ventilation opening 8, so as to ensure the formation of convective heat dissipation between the first ventilation opening 7 and the second ventilation opening 8.

[0048] Refer to Figure 4 As shown, the fan 6 is located below the first reactor box 2. A water blocking structure is provided in the spacing between the second side wall 24 and the motor bracket 1. The water blocking structure is located below the second ventilation opening 8, and the water blocking structure is used to block the water lifted by the fan 6 from entering the second ventilation opening 8 through the spacing between the second side wall 24 and the motor bracket 1.

[0049] In this technical solution, after rainwater enters the housing of the outdoor unit, if the fan 6 is in the working state, the fan 6 will cause the rainwater to splash, and the splashed rainwater will enter the gap between the second side wall 24 and the motor bracket 1. Since a water-blocking structure is provided within the distance between the second side wall 24 and the motor bracket 1, the water-blocking structure will block the splashed rainwater, preventing the rainwater from reaching the second ventilation opening 8, thereby preventing the rainwater brought up by the fan 6 from entering the first reactor box 2. In the prior art, the disadvantage of fixing the reactor on the wind-shielding vertical plate of the air conditioner outdoor unit is that: a separate water-proof cover needs to be designed for the reactor, occupying the internal space of the outdoor unit, increasing the size of the housing, resulting in inconvenient installation and after-sales service. However, in this application, by providing a water-blocking structure within the distance between the second side wall 24 and the motor bracket 1, it is possible to prevent the splashed rainwater from entering the first reactor box 2, playing a waterproof role, thus eliminating the need to separately design a water-proof cover, without increasing the volume of the housing, while reducing the overall cost of the machine and effectively solving the problem of inconvenient installation and after-sales service.

[0050] Referring to Figure 4 and Figure 5 As shown, the water-blocking structure includes a first convex protrusion 11 and a second convex protrusion 12. The first convex protrusion 11 is formed on the side of the motor bracket 1 facing the second side wall 24, and the first convex protrusion 11 protrudes towards the side where the second side wall 24 is located. The second convex protrusion 12 is formed on the second side wall 24, and the second convex protrusion 12 protrudes towards the side where the motor bracket 1 is located. The first convex protrusion 11 and the second convex protrusion 12 are vertically offset and overlap each other.

[0051] In this technical solution, the vertical offset and mutual overlap of the first convex protrusion 11 and the second convex protrusion 12 can form a double-layer obstruction, which can completely isolate the gap formed between the second side wall 24 and the motor bracket 1, having a very good water-blocking effect. It should be noted that a flanging is provided on the side of the motor bracket 1 facing the second side wall 24, and the first convex protrusion 11 is formed on this flanging. Since the combination of the first convex protrusion 11 and the second convex protrusion 12 is required to prevent the splashed rainwater from entering the second ventilation opening 8, preferably, only one row of the second ventilation openings 8 is provided, and this row of second ventilation openings 8 is close to the top of the second side wall 24, so that the length of the flanging extending downward is short, and the expanded area of the motor bracket 1 in the width direction is small, thereby saving costs.

[0052] As a specific implementation manner, the width of the overlapping part of the first convex protrusion 11 and the second convex protrusion 12 is h2, preferably, 1mm ≤ h2 ≤ h1. This can ensure that there is enough overlap between the first convex protrusion 11 and the second convex protrusion 12, ensuring a good obstructive effect on the splashed rainwater.

[0053] Referring to Figure 3 and Figure 8As shown, the first reactor box 2 also has a bottom wall 25. The bottom wall 25 is located between the first heat exchange part 41 and the motor support 1, and the bottom wall 25 is connected to the first side wall 23. A drain hole 10 is formed on the bottom wall 25, and the drain hole 10 is close to the connection of the bottom wall 25 and the first side wall 23.

[0054] In the embodiment, external rainwater basically only enters the first reactor box 2 through the first vent 7. When the drain hole 10 formed on the bottom wall 25 is close to the connection of the bottom wall 25 and the first side wall 23, the rainwater entering the first reactor box 2 can be quickly discharged through the drain hole 10.

[0055] Combined with reference to Figure 1 and Figure 6 As shown, the first reactor box 2 also has a third flanging 26, and the third flanging 26 is fixed to the top of the panel 14 by a third fastener.

[0056] In this technical solution, when the third flanging 26 of the first reactor box 2 is fixed to the top of the panel 14 of the housing by a third fastener, it shows that the panel 14 also plays a supporting role for the first reactor box 2 and the first reactor 3. This can not only share the pressure of the first side plate 5 and the motor support 1, but also play a role in enhancing the strength of the panel 14. It can be understood that the first fastener, the second fastener and the third fastener can all be screws.

[0057] Combined with reference to Figure 6 and Figure 7 As shown, the first reactor box 2 also has a third side wall 27. The third side wall 27 is opposite to the panel 14, and a third vent 13 is formed on the third side wall 27.

[0058] In this embodiment, both sides of the third side wall 27 are connected to the first side wall 23 and the second side wall 24 respectively. When a third vent 13 is formed on the third side wall 27 of the first reactor box 2 and the third vent 13 is in the suction negative pressure area of the fan 6, not only can a convective heat dissipation be formed between the first vent 7 and the second vent 8, but also an oblique convective heat dissipation will be formed between the first vent 7 and the third vent 13, thereby further improving the heat dissipation effect of the first reactor 3. Preferably, the number of the third vents 13 is multiple, and the multiple third vents 13 are sequentially and spaced apart along the height direction of the third side wall 27. The increase in the number of the third vents 13 can enhance the convective effect between the first vent 7 and the third vent 13, thereby improving the heat dissipation effect.

[0059] It should be noted that the first reactor box 2 further has a fourth flanging 28 and a fourth side wall 29. The fourth side wall 29 is opposite to the third side wall 27. The first side wall 23, the second side wall 24, the third side wall 27, the fourth side wall 29 and the bottom wall 25 enclose a receiving chamber of the first reactor box 2. The first flanging 21, the second flanging 22, the third flanging 26 and the fourth flanging 28 respectively extend outward from the tops of the first side wall 23, the second side wall 24, the third side wall 27 and the fourth side wall 29. The outdoor heat exchanger 4 further includes a second heat exchange part 42 bent relative to the first heat exchange part 41. The second heat exchange part 42 is opposite to the back surface of the housing. The fourth flanging 28 of the first reactor box 2 overlaps on the top of the second heat exchange part 42, that is, the second heat exchange part 42 also supports the first reactor box 2, making the force on the first reactor box 2 uniform.

[0060] As a specific implementation manner, while constructing ventilation openings on the first reactor box 2 for heat dissipation, it should also be considered that when the height of the ventilation openings is too high, it is easy to cause insects to enter. To prevent insects from entering the first reactor box 2, preferably, the heights of the first ventilation opening 7, the second ventilation opening 8, and the third ventilation opening 13 are all less than or equal to 3 mm.

[0061] See Figure 3 As shown, an air outlet is formed on the panel 14. A fan guide ring 15 is assembled on the panel 14. The fan guide ring 15 is located between the air outlet and the fan 6. The first reactor box 2 is located above the fan 6. The fan guide ring 15 has a side edge facing away from the panel 14. The third side wall 27 is located between the panel 14 and the side edge of the fan guide ring 15. The vertical distance between the third side wall 27 and the side edge of the fan guide ring 15 is greater than or equal to 10 mm.

[0062] In this technical solution, when the third side wall 27 is located between the panel 14 and the side edge of the fan guide ring 15, and the vertical distance between the third side wall 27 and the side edge of the fan guide ring is greater than or equal to 10 mm, it indicates that the third side wall 27 of the first reactor box 2 has been effectively blocked by the fan guide ring 15. Then, when the fan 6 works, the rainwater it brings up will only splash onto the bottom wall 25 of the first reactor box 2 and will not splash onto the third side wall 27, so it will not enter the first reactor box 2 through the third ventilation opening 13, thus achieving the waterproof effect.

[0063] Combined with see Figure 1 and Figure 2 As shown, a hollowed-out area is formed on the motor bracket 1. A second reactor box 16 is installed on the motor bracket 1, and the second reactor box 16 is located within the hollowed-out area. A second reactor 17 is arranged in the second reactor box 16.

[0064] In this embodiment, both sides of the second reactor box 16 have two flanges, and these two flanges are respectively fixed to the top of the motor bracket 1 by screws, so as to fix the second reactor box 16 on the motor bracket 1. By installing the second reactor box 16 containing the second reactor 17 on the motor bracket 1, not only is the effective support for the second reactor box 16 and the second reactor 17 realized, but also the second reactor box 16 is located in the hollowed-out area on the motor bracket 1 for avoidance, which makes the volume of the outdoor unit not increase after the second reactor box 16 is installed. It should be noted that there are a total of three reactors in the outdoor unit of this application. The space at the location of the first reactor box 2 is limited, which limits the size design of the first reactor box 2. Eventually, only two first reactors 3 can be placed in the first reactor box 2. Therefore, the remaining second reactor 17 also needs to be installed on the motor bracket 1 with the help of the second reactor box 16. Among them, both the first reactor box 2 and the second reactor box 16 are made of steel.

[0065] See Figure 3 As shown, the second reactor box 16 is located above the fan 6. The second reactor box 16 has a wall body opposite to the panel. This wall body is located between the side edges of the panel 14 and the fan guide ring 15, and the vertical distance between this wall body and the side edge of the fan guide ring 15 is greater than or equal to 10 mm.

[0066] In this technical solution, when the wall body of the second reactor box 16 opposite to the panel is located between the side edges of the panel 14 and the fan guide ring 15, and the vertical distance between this wall body and the side edge of the fan guide ring 15 is greater than or equal to 10 mm, it indicates that this wall body has been effectively blocked by the fan guide ring 15. Then, when the fan 6 works, the rainwater it brings up will only splash onto the bottom surface of the second reactor box 16 and will not splash onto this wall body, nor will it enter the first reactor box 2 along this wall body, thus achieving the waterproof effect.

[0067] It should also be noted that a partition 18 is further provided in the housing of the outdoor unit. The partition 18 is the wind separating vertical plate mentioned in the background art.
