Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner. Background Art

[0002] With the continuous improvement of the aesthetic effect of building facades, more and more building grilles are provided outside the outdoor unit of the air conditioner to place the outdoor unit of the air conditioner.

[0003] In the prior art, a flow guiding structure is generally arranged near the fan to ensure that the air flow in the outdoor unit of the air conditioner can be smoothly discharged through the air outlet, only to gather the hot air in the outdoor unit of the air conditioner and discharge it from the air outlet through the flow guiding structure.

[0004] However, the inside of the building grille is a relatively closed environment. After the air flow in the traditional outdoor unit of the air conditioner is discharged through the air outlet, due to the setting of the building grille, the air flow at the air outlet cannot be discharged from the building grille in time, which will cause the temperature inside the grille to continuously increase, reduce the refrigeration effect of the outdoor unit of the air conditioner, and even cause shutdown.

[0038] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0039] Below, reference is made to Figures 1 - 11 Describe the outdoor unit 100 of an air conditioner according to an embodiment of the present utility model.

[0040] With reference to Figures 1 - 3 As shown, the outdoor unit 100 of an air conditioner according to an embodiment of the present utility model includes: a casing 10, an outdoor heat exchanger 20, and a grille 30. The casing 10 includes a chassis 11 and a panel 12. The panel 12 is connected to the chassis 11, and the chassis 11 can provide an installation position and support force for the panel 12.

[0041] The panel 12 is formed with an air outlet 13, which can facilitate the outdoor air to enter the indoor unit of the air conditioner through the air outlet 13 for heat exchange. After the heat exchange is completed, the fan can blow the air after heat exchange out of the air outlet 13 to the outside, thereby improving the heat exchange efficiency of the outdoor unit 100 of the air conditioner.

[0042] The outdoor heat exchanger 20 is disposed on the chassis 11. The outdoor heat exchanger 20 is disposed at the rear side of the panel 12. The outdoor heat exchanger 20 and the air outlet 13 are arranged opposite to each other front and back, so that the outdoor air that has passed through the outdoor heat exchanger 20 can be discharged from the casing 10 through the air outlet 13.

[0043] Specifically, outdoor air can flow into the interior of the outdoor unit 100 of the air conditioner through the air outlet 13, which can accelerate the heat dissipation process of the gas in the outdoor heat exchanger 20, and discharge a part of the heat from the air outlet 13 of the panel 12, thereby accelerating the cooling speed inside the outdoor unit 100 of the air conditioner. Moreover, the setting of the air outlet 13 can ensure unobstructed ventilation inside the outdoor unit 100 of the air conditioner, avoid the retention of internal gas, reduce the situation of over-high temperature inside the outdoor unit 100 of the air conditioner, and thus extend the service life of the outdoor unit 100 of the air conditioner.

[0044] The mesh cover 30 is arranged on the panel 12, and the mesh cover 30 covers the air outlet 13. The mesh cover 30 can prevent dust and direct sunlight. After the outdoor unit 100 of the air conditioner operates for a long time, a large amount of dust will accumulate on the surface. If these dusts are not cleaned in time, heat dissipation will be blocked, affecting the operating efficiency of the air conditioner. At the same time, direct sunlight will also accelerate the aging of the outdoor unit 100 of the air conditioner. Therefore, the mesh cover 30 can effectively prevent these situations from occurring, thereby extending the service life of the outdoor unit 100 of the air conditioner.

[0045] Since the outdoor unit of this air conditioner is generally arranged in the building grille 60, when outdoor air needs to enter the interior of the outdoor unit 100 of the air conditioner through the air outlet 13 of the mesh cover 30, the presence of the building grille 60 will block the air outlet 13 of the mesh cover 30, reducing the air intake of the air outlet 13 of the mesh cover 30, and thus reducing the heat exchange efficiency of the outdoor unit 100 of the air conditioner.

[0046] In addition, the interior of the building grille 60 is a relatively enclosed environment. The hot air of the traditional outdoor unit of the air conditioner will directly flow out from the air outlet of the mesh cover, and a part of the hot air will flow back under the obstruction of the building grille, resulting in most of the hot air gathering inside the building grille.

[0047] If the hot air of the outdoor unit of the air conditioner cannot be effectively discharged from the building grille, it will cause the temperature inside the building grille to continuously increase, reducing the refrigeration effect of the outdoor unit of the air conditioner and even causing shutdown.

[0048] Therefore, the outdoor unit 100 of this air conditioner further includes: a deflector 40, the deflector 40 is installed on the panel 12 and / or the mesh cover 30, the deflector 40 extends along the circumference of the mesh cover 30, and the deflector 40 is used to guide the heat exchange air discharged from the mesh cover 30 forward.

[0049] The deflector 40 is installed on the panel 12 and / or the mesh cover 30, that is to say, the deflector 40 can be arranged on the panel 12, and the deflector 40 extends from the outer surface of the panel 12 through the mesh cover 30 in a direction away from the outdoor heat exchanger 20, so as to continue to guide the heat exchange air discharged from the mesh cover 30 forward.

[0050] The flow guide member 40 can extend to the building grille 60, so that the heat exchange air discharged from the mesh cover 30 can be directly conveyed outside the building grille 60, thereby reducing the temperature inside the building grille 60, improving the heat exchange efficiency of the outdoor unit 100 of the air conditioner, and enhancing the refrigeration effect of the outdoor unit 100 of the air conditioner.

[0051] Alternatively, the flow guide member 40 can be arranged on the mesh cover 30, and the flow guide member 40 extends from the air outlet 13 of the mesh cover 30 in a direction away from the outdoor heat exchanger 20, thereby continuing to guide the heat exchange air discharged from the mesh cover 30 forward.

[0052] In addition, the flow guide member 40 is arranged along the circumferential direction of the mesh cover 30. Thus, the flow guide member 40 can block the circumferential edge of the mesh cover 30. When the hot air blows out from the air outlet 13 of the mesh cover 30, the flow guide member 40 can play a role in guiding the flow direction, thereby preventing the hot air at the air outlet 13 from directly diverging around and avoiding the generation of backflow.

[0053] Wherein, the front edge of the flow guide member 40 protrudes from the front surface of the mesh cover 30 in the direction from back to front, thereby increasing the forward flow guiding distance of the flow guide member 40.

[0054] Specifically, the front edge of the flow guide member 40 protrudes in a direction away from the mesh cover 30, so that the air discharged from the air outlet 13 of the mesh cover 30 does not directly diffuse around.

[0055] Due to the arrangement of the flow guide member 40, the air discharged from the air outlet 13 of the mesh cover 30 will be gathered by the flow guide member 40, and then the flow guide member 40 guides the hot air to the building grille 60, thereby accelerating the speed of conveying the hot air outside the building grille 60. This can avoid the increase in temperature inside the building grille 60, thereby improving the heat exchange efficiency of the outdoor unit 100 of the air conditioner and enhancing the refrigeration effect of the outdoor unit 100 of the air conditioner.

[0056] Therefore, the front edge of the flow guide member 40 in the outdoor unit 100 of the air conditioner protrudes from the front surface of the mesh cover 30 in the direction from back to front, which can not only increase the forward flow guiding distance of the flow guide member 40, but also accelerate the speed of conveying the hot air outside the building grille 60, and avoid the occurrence of backflow phenomenon. This can avoid the increase in temperature inside the building grille 60 and enhance the refrigeration effect of the outdoor unit 100 of the air conditioner.

[0057] According to a specific embodiment of the present invention, as Figure 1 shown, the flow guide member 40 is configured as an annular structure, and the flow guide member 40 surrounds the mesh cover 30.

[0058] Specifically, the annular flow guide member 40 can help the outdoor unit 100 of the air conditioner dissipate heat more effectively, thereby improving the heat dissipation effect of the outdoor unit 100 of the air conditioner, reducing the operating temperature of the outdoor unit 100 of the air conditioner, and thus extending its service life.

[0059] Moreover, the arrangement of the annular flow guide member 40 can guide the air flow direction, reduce the turbulence of the air in the air duct, smooth the changes in the speed and direction of the air flow, and reduce the impact of the wind pressure difference on the air duct and other components, thereby reducing the noise generated when the air flows.

[0060] In addition, the annular flow guide member 40 can help increase the air flow rate, make the air flow through the outdoor heat exchanger 20 of the outdoor unit 100 of the air conditioner more evenly, and effectively prevent external substances such as sand, dust, and sundries from invading the interior of the outdoor unit 100 of the air conditioner, thereby reducing the occurrence of failures of the outdoor unit 100 of the air conditioner.

[0061] According to some embodiments of the present invention, the distance between the front edge of the flow guide member 40 and the front surface of the panel 12 is d1, and d1 satisfies the relationship: 25 mm < d1 < 60 mm.

[0062] Among them, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is greater than the first parameter value. If the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is less than or equal to the first parameter value, it will affect the forward flow guiding distance of the flow guide member 40. The flow guiding distance is the air guiding distance. The air guiding distance of the flow guide member 40 decreases, and the effect of conveying hot air is poor, and the air cannot be effectively conveyed outside the building grille 60. Therefore, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 cannot be less than or equal to the first parameter value.

[0063] The first parameter value can be 20 mm - 25 mm. Preferably, the first parameter value can be 25 mm. When the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 25 mm, the hot air conveyed by the flow guide member 40 just approaches the periphery of the building grille 60, and a large amount of hot air will still flow in the inner area of the building grille 60 and cannot effectively flow outside the building grille 60.

[0064] The value range of the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 can be from 25 mm to 30 mm. Preferably, when the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 30 mm, the distance from the flow guide member 40 to the front surface of the panel 12 is relatively large, the air guiding distance of the flow guide member 40 is relatively far, the air guiding effect of the flow guide member 40 is better, and further, the air outlet of the outdoor unit 100 of the air conditioner can be guided to a position farther from the panel 12.

[0065] Further, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is less than the second parameter value. If the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is greater than or equal to the second parameter value, the volume of the flow guide member 40 will also increase accordingly, and the space occupied by the flow guide member 40 will be larger, resulting in an increase in the volume of the entire outdoor unit 100 of the air conditioner, which is not convenient for the installation of the outdoor unit 100 of the air conditioner and will also cause interference between the flow guide member 40 and the building grille 60. Therefore, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 cannot be greater than or equal to the second parameter value.

[0066] The second parameter value can be 60 mm - 65 mm. Preferably, the second parameter value can be 60 mm. When the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 60 mm, the flow guide member 40 just contacts the building grille 60, which can enable a large amount of hot air to effectively flow outside the building grille 60.

[0067] The value range of the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 can be 30 mm to 60 mm. Preferably, if the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 59 mm, this can ensure that the distance between the flow guide member 40 and the building grille 60 is relatively close. Moreover, it can also avoid the extrusion and collision between the flow guide member 40 and the building grille 60 due to the excessive distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12. It can also make the air guiding distance of the flow guide member 40 farther, and the air guiding effect of the flow guide member 40 is better, so as to guide the air outlet of the outdoor unit 100 of the air conditioner to a position farther from the panel 12.

[0068] According to some embodiments of the present invention, as Figure 2 shown, d1 satisfies the relationship: 30 mm < d1 < 40 mm.

[0069] Among them, to further optimize the air guiding effect of the flow guide member 40, through experimental verification, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is limited within the range of 30 mm to 40 mm, and the air guiding effect of the flow guide member 40 is more obvious.

[0070] Among them, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is greater than the third parameter value. If the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is less than or equal to the third parameter value, the forward air guiding distance of the flow guide member 40 will be affected, the air guiding distance of the flow guide member 40 will decrease, the effect of conveying hot air will be poor, and the air guiding effect will decrease. Therefore, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 cannot be less than or equal to the third parameter value.

[0071] The value of the third parameter can be 25 mm - 30 mm. Preferably, the value of the third parameter can be 30 mm. When the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 30 mm, the flow guiding effect of the flow guide member 40 just changes, and there will still be a large amount of hot air flowing in the inner area of the building grille 60 and unable to effectively flow outside the building grille 60.

[0072] The value range of the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 can be 30 mm to 35 mm. Preferably, when the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 35 mm, the distance from the flow guide member 40 to the front surface of the panel 12 can be relatively large, the air guiding distance of the flow guide member 40 can be relatively far, and the air guiding effect is more obvious.

[0073] In addition, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is less than the fourth parameter value. If the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is greater than or equal to the fourth parameter value, it will waste materials and increase costs. Moreover, the flow guiding effect of the flow guide member 40 decreases and the air guiding effect is not obvious. Therefore, the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 cannot be greater than or equal to 40 mm.

[0074] The fourth parameter value can be 40 mm - 45 mm. Preferably, the first parameter value can be 40 mm. When the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 40 mm, the improvement of the flow guiding effect of the flow guide member 40 is gentle and has approached the maximum flow guiding effect.

[0075] The value range of the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 can be 35 mm to 40 mm. Preferably, when the distance d1 between the front edge of the flow guide member 40 and the front surface of the panel 12 is 35 mm, the flow guiding effect of the flow guide member 40 is better, the air guiding distance is long, and the air guiding effect is obvious.

[0076] According to some embodiments of the present invention, there is an angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13, and α satisfies the relationship: 0 ≤ α ≤ 35°.

[0077] Among them, the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is not less than 0°. If the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is less than 0°, it will affect the forward air outlet range of the flow guide member 40, resulting in a smaller forward air outlet range of the flow guide member 40 and a poorer air outlet effect. Therefore, the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is not less than 0°.

[0078] The value range of the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 can be from 0 to 15°. Preferably, when the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is 15°, the angle between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is relatively large, the air outlet range of the flow guide member 40 is relatively far, and the effect of the flow guide member 40 in gathering the wind field is better.

[0079] In addition, the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is not greater than the fifth parameter value. If the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is greater than the fifth parameter value, the effect of the flow guide member 40 in gathering the wind field will decrease, thereby affecting the effect of discharging hot air from the building grille 60. Therefore, the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 cannot be greater than the fifth parameter value.

[0080] The fifth parameter value can be from 35° to 40°. Preferably, the fifth parameter value can be 35°. When the angle between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is 35°, the effect of gathering wind at the air outlet 13 just decreases, and the air at the air outlet 13 cannot be effectively gathered and discharged outside the building grille 60.

[0081] The range of the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is from 30° to 35°. Preferably, when the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is 35°, the angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13 is larger, which can make the effect of the flow guide member 40 in gathering the wind field greater, and can also avoid the diffusion of the air at the air outlet 13 due to the too large angle α between the inner surface of the flow guide member 40 and the central axis of the air outlet 13, thereby accelerating the discharge of hot air from the building grille 60.

[0082] According to some embodiments of the present invention, as Figure 1 shown, the front surface of the mesh cover 30 protrudes from the front surface of the panel 12 in the direction from back to front, and the flow guide member 40 is sleeved on the outer periphery of the mesh cover 30.

[0083] Among them, the setting of the mesh cover 30 can provide an installation position for the flow guide member 40, and can also further increase the flow guiding distance of the flow guide member 40, thereby increasing the speed of outwardly conveying hot air and achieving the effect of reducing the temperature of the outdoor unit 100 of the air conditioner.

[0084] According to some embodiments of the present invention, as Figure 2 shown, the distance between the rear edge of the flow guide member 40 and the front surface of the panel 12 is d2, and the distance between the rear edge and the front edge of the flow guide member 40 is d3. d2 and d3 satisfy the relationship: d2 < d3.

[0085] Among them, the distance d2 between the rear edge of the deflector 40 and the front surface of the panel 12 is less than the distance d3 between the rear edge and the front edge of the deflector 40.

[0086] In this way, not only can it be ensured that the rear edge of the deflector 40 is relatively close to the front surface of the panel 12, which can prevent the hot air at the front surface of the panel 12 from spreading and reduce the air outlet effect, but also it can be ensured that the front edge of the deflector 40 protrudes forward by a longer distance, so that the deflector distance of the deflector 40 can be extended, the air gathering effect can be improved, and the hot air can be quickly discharged from the building grille.

[0087] According to some embodiments of the present invention, the grille 30 and the panel 12 are integrally formed, and / or the deflector 40 is detachably installed on the panel 12 and / or the grille 30.

[0088] Among them, the integrally formed design of the grille 30 and the panel 12 can improve the overall strength and stability of the grille 30 and the panel 12, and can also make it more durable and not easily deformed. Moreover, the integrally formed design of the grille 30 and the panel 12 can reduce the vibration and noise during the operation of the outdoor unit 100 of the air conditioner, thereby improving the user experience.

[0089] Furthermore, the integrally formed grille 30 and panel 12 can reduce the number of components and the difficulty of maintenance and cleaning, thereby improving the maintainability of the outdoor unit 100 of the air conditioner.

[0090] In addition, the deflector 40 is detachably installed on the panel 12 and / or the grille 30, that is to say, the deflector 40 is detachably installed on the panel 12, or the deflector 40 is detachably installed on the grille 30. In this way, it is convenient for the repair and replacement of the deflector 40 and can also adapt to different scenario requirements.

[0091] According to some embodiments of the present invention, the grille 30 is provided with a first clamping portion, and the panel 12 or the grille 30 is provided with a second clamping portion, and the first clamping portion and the second clamping portion are clamped and matched, and / or the grille 30 is provided with a first mounting hole, and the panel 12 or the grille 30 is provided with a second mounting hole, and the first mounting hole and the second mounting hole are installed through fasteners.

[0092] Among them, the first clamping portion of the grille 30 can be set as a clamping protrusion, and the second clamping portion of the panel 12 can be set as a clamping groove, or the grille 30 is provided with a second clamping portion, the second clamping portion is a clamping groove, and the panel 12 is provided with a clamping protrusion, and the clamping protrusion and the clamping groove are clamped and matched, which can not only avoid the use of screws but also facilitate the installation and disassembly of the grille 30 and the panel 12.

[0093] Alternatively, the wire mesh cover 30 is provided with a first mounting hole. Correspondingly, the panel 12 is provided with a second mounting hole. A fastener passes through the first mounting hole and the second mounting hole for fixed connection. The fastener can be a screw. In this way, the wire mesh cover 30 and the panel 12 can be connected more firmly.

[0094] An outdoor unit 100 of an air conditioner according to a second aspect embodiment of the present utility model includes: a housing 10, an outdoor heat exchanger 20, and a wire mesh cover 30. The housing 10 includes a chassis 11 and a panel 12. The panel 12 is connected to the chassis 11. The panel 12 is formed with an air outlet 13. The outdoor heat exchanger 20 is disposed on the chassis 11. The outdoor heat exchanger 20 is disposed at the rear side of the panel 12. The outdoor heat exchanger 20 and the air outlet 13 are disposed opposite to each other front and back. Thus, the outdoor air that has exchanged heat through the outdoor heat exchanger 20 can be discharged from the air outlet 13 of the housing 10.

[0095] Specifically, the outdoor air can flow into the outdoor unit 100 of the air conditioner through the air outlet 13, which can accelerate the heat dissipation process of the gas in the outdoor heat exchanger 20, and discharge a part of the heat from the air outlet 13 of the panel 12. Thus, the cooling speed inside the outdoor unit 100 of the air conditioner can be increased. Moreover, the setting of the air outlet 13 can ensure smooth ventilation inside the outdoor unit 100 of the air conditioner, avoid the retention of internal gas, reduce the situation of too high temperature inside the outdoor unit 100 of the air conditioner, and thus can extend the service life of the outdoor unit 100 of the air conditioner.

[0096] The wire mesh cover 30 is disposed on the panel 12. The wire mesh cover 30 covers the air outlet 13. The outdoor unit 100 of the air conditioner further includes: a deflector 40. The deflector 40 is installed on the panel 12 and / or the wire mesh cover 30. Wherein, the front edge of the deflector 40 protrudes from the front surface of the wire mesh cover 30 in the direction from back to front. Thus, the forward deflection distance of the deflector 40 can be increased.

[0097] Specifically, the wire mesh cover 30 is disposed on the panel 12. The wire mesh cover 30 covers the air outlet 13. The wire mesh cover 30 can prevent dust and direct sunlight. After the outdoor unit 100 of the air conditioner operates for a long time, a large amount of dust will accumulate on the surface. If these dusts are not cleaned in time, it will prevent heat dissipation and affect the operating efficiency of the air conditioner. At the same time, direct sunlight will also accelerate the aging of the outdoor unit 100 of the air conditioner. Therefore, the wire mesh cover 30 can effectively prevent these situations from occurring, and thus can extend the service life of the outdoor unit 100 of the air conditioner.

[0098] The front edge of the deflector 40 protrudes away from the wire mesh cover 30, so that the air discharged from the air outlet 13 of the wire mesh cover 30 will not directly diffuse around.

[0099] Due to the arrangement of the flow guide member 40, the air flow from the air outlet 13 of the mesh cover 30 will be gathered by the flow guide member 40, and then the flow guide member 40 guides the hot air to the building grille 60, thereby accelerating the speed of delivering the hot air outside the building grille 60. This can avoid the increase in the temperature inside the building grille 60, thereby improving the heat exchange efficiency of the outdoor unit 100 of the air conditioner and enhancing the cooling effect of the outdoor unit 100 of the air conditioner.
