Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an outdoor unit for an air conditioner. Background Technology

[0002] An air conditioner outdoor unit includes a casing, inside which are installed components such as a compressor, outdoor heat exchanger, and fan. The casing has an air outlet and an air return vent. Driven by the fan, air flows into the casing through the air return vent, undergoes heat exchange in the outdoor heat exchanger, and then flows out through the air outlet. A grille is installed at the air outlet. The grille includes ribs, with gaps between adjacent ribs to allow airflow.

[0003] There is a type of grille with straight, linear ribs that have no variation in shape. When air flows through the grille, the ribs create resistance to the airflow, resulting in high wind resistance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] In response to the problems pointed out in the background art, this utility model proposes an outdoor unit for an air conditioner with a grille that provides low airflow resistance.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0007] In some embodiments of this application, an outdoor unit of an air conditioner is provided, with an air outlet on the casing; an outdoor heat exchanger and a fan are disposed inside the casing; a grille is disposed at the air outlet; the grille includes multiple sub-regions, which are arranged sequentially along the width direction of the grille; multiple transverse ribs are disposed in any sub-region, which are spaced apart along the height direction of the grille, and any transverse rib extends along the width direction of the grille; the windward surface of the transverse ribs located in different sub-regions has a different tilt angle relative to the air outlet direction of the outdoor unit of the air conditioner.

[0008] The above technical solution has the following advantages or beneficial effects: the air is accelerated by the fan and blown out in a spiral shape.

[0041] In some embodiments of this application, an air conditioner is provided that performs a refrigeration cycle or a heating cycle by using a compressor, a condenser, an expansion valve, and an evaporator.

[0042] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0043] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0044] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in either the indoor or outdoor unit.

[0045] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0046] In some embodiments of this application, an outdoor unit is provided. Figure 1 This is a schematic diagram of an outdoor unit.

[0047] The outdoor unit includes a housing 100. The housing 100 forms the external outline of the outdoor unit. For example, the housing 100 has a rectangular structure. An air outlet 120 is provided on the housing 100. A return air inlet 110 is also provided on the housing 100. For example, the return air inlet 110 is provided on the rear side of the housing 100, and the air outlet 120 is provided on the front side of the housing 100.

[0048] For ease of description below, this embodiment defines a spatial coordinate system (XYZ), where the X, Y, and Z axes are perpendicular to each other. The X-axis runs along the width of the casing 100, and the Y-axis runs along the air outlet direction of the outdoor unit. (Refer to...) Figure 1 The width of the housing 100 is denoted as W1, and the height of the housing 100 is denoted as H1.

[0049] The outdoor unit also includes an outdoor heat exchanger. The outdoor heat exchanger is located inside the casing 100. The outdoor heat exchanger is configured to exchange heat with the air flowing through it.

[0050] The outdoor unit also includes a fan. The fan is located inside the housing 100. The fan is configured to provide power for airflow.

[0051] When the fan starts, outside air enters the interior of the casing 100 through the return air inlet 110, undergoes heat exchange as it flows through the outdoor heat exchanger, and then flows out through the air outlet 120 after heat exchange.

[0052] The outdoor unit also includes a grille 200. The grille 200 is located at the air outlet 120. Figure 2 This is a structural diagram viewed from the air outlet side of the grille 200. Figure 8 This is a structural diagram viewed from the windward side of the grille 200. The width direction of the grille 200 is denoted as W2, and the height direction of the grille 200 is denoted as H2. The width direction W2 of the grille 200 is parallel to the X-axis, and the height direction H2 of the grille 200 is parallel to the Z-axis.

[0053] In some embodiments of this application, reference is made to Figure 2 The grille 200 includes multiple sub-regions 260, which are arranged sequentially along the width direction W2 of the grille 200. Each sub-region 260 is a region defined by ribs and the border of the grille 200. For example, Figure 2 The grid 200 shown includes three sub-regions 260, referred to as the first sub-region 261, the second sub-region 262, and the third sub-region 263. The first sub-region 261, the second sub-region 262, and the third sub-region 263 are arranged sequentially along the width direction W2 of the grid 200, with the second sub-region 262 located between the first sub-region 261 and the third sub-region 263.

[0054] Figure 3 for Figure 2 The first sub-region 261 of the grid 200 shown is a cross-sectional view along the AA direction. Figure 4 for Figure 2 The second sub-region 262 of the grid 200 shown is a cross-sectional view along the BB direction. Figure 5 for Figure 2 The third sub-region 263 of the grid 200 shown is a cross-sectional view along the CC direction. Figures 3 to 5 The dashed arrows in the diagram represent the direction of airflow.

[0055] In some embodiments of this application, the grille 200 further includes transverse ribs 210. Multiple transverse ribs 210 are provided within any sub-region 260, and the multiple transverse ribs 210 are arranged at intervals along the height direction H2 of the grille 200. Each transverse rib 210 extends along the width direction W2 of the grille 200.

[0056] For example, Figure 2 In the grid 200 shown, the transverse ribs 210 in the first sub-region 261 are designated as the first transverse ribs 211, the transverse ribs 210 in the second sub-region 262 are designated as the second transverse ribs 212, and the transverse ribs 210 in the third sub-region 263 are designated as the third transverse ribs 213.

[0057] In some embodiments of this application, the distance between two adjacent horizontal ribs 210 is denoted as d1, and d1 is 7.9 mm, which meets the safety requirements for children's finger-testing.

[0058] In some embodiments of this application, reference is made to Figure 2 and Figure 6 , Figure 6 for Figure 2 Enlarged view of section D. The grille 200 also includes a plurality of spaced longitudinal ribs 220, which intersect with a plurality of transverse ribs 210.

[0059] The spacing between two adjacent longitudinal ribs 220 is denoted as d2, and the value of d2 ranges from 48 to 52 mm, for example, d2 is 50 mm. The longitudinal ribs 220 serve to reinforce the transverse ribs 210, ensuring that the transverse ribs 210 undergo limited deformation under a set force (e.g., a force of 4 N), still meeting the safety requirements for children's finger-testing tests, while also preventing excessive vertical rib density from affecting airflow.

[0060] In some embodiments of this application, the plurality of longitudinal ribs 220 include at least one first longitudinal rib 221 and a plurality of second longitudinal ribs 222, wherein the extension dimension of the first longitudinal rib 221 along the air outlet direction is greater than the extension dimension of the second longitudinal ribs 222 along the air outlet direction. The first longitudinal rib 221 and the frame of the grille 200 form a sub-region 260.

[0061] In other words, the extension dimension of the first longitudinal stiffener 221 along the Y-axis is denoted as a1, and the extension dimension of the second longitudinal stiffener 222 along the Y-axis is denoted as a2, where a1 > a2.

[0062] like Figure 2 The grid 200 shown includes two first longitudinal ribs 221 and multiple second longitudinal ribs 222. The two first longitudinal ribs 221 are arranged at intervals along the width direction W2 of the grid 200, dividing the grid 200 into three sub-regions 260. One of the first longitudinal ribs 221 forms a first sub-region 261 with one side vertical frame 251 and the two upper and lower horizontal frames 252 of the grid 200. The other first longitudinal rib 221 forms a third sub-region 263 with the opposite side vertical frame 251 and the two upper and lower horizontal frames 252 of the grid 200. The two first longitudinal ribs 221 form a second sub-region 262 with the two upper and lower horizontal frames 252 of the grid 200.

[0063] The first longitudinal rib 221 serves to divide the sub-region 260. The first longitudinal rib 221 is thicker than the second longitudinal rib 222. The first longitudinal rib 221 provides support and reinforcement to the transverse ribs 210 located in the middle region of the grid 200, thereby improving the structural strength of the grid 200.

[0064] In some embodiments of this application, multiple transverse ribs 210 located in different sub-regions 260 are arranged in a one-to-one correspondence. In other words, the transverse ribs 210 located in different sub-regions 260 extend in the same transverse direction. In this way, the multiple transverse ribs 210 in multiple sub-regions 260 are distributed in a coordinated and uniform manner on the main surface of the air outlet side of the grille 200.

[0065] The two adjacent transverse reinforcing bars 210 are connected at the first longitudinal reinforcing bar 221, and the first longitudinal reinforcing bar 221 serves as the connecting bar for the transverse reinforcing bars 210.

[0066] For example, Figure 2 In the grid 200 shown, multiple first transverse ribs 211, multiple second transverse ribs 212, and multiple third transverse ribs 213 are arranged in a one-to-one correspondence.

[0067] A type of grille has horizontal ribs that are straight bars extending horizontally along the airflow direction, with no change in shape. When air flows out of the grille, the horizontal ribs create resistance to the airflow, resulting in high wind resistance.

[0068] To address the technical problem of high airflow resistance caused by the grille, in some embodiments of this application, the windward face 214 of the transverse ribs 210 located in different sub-regions 260 has different inclination angles relative to the air outlet direction of the outdoor unit of the air conditioner.

[0069] In other words, the windward face 214 of the transverse ribs 210 located in different sub-regions 260 has different inclination angles relative to the Y-axis.

[0070] For example, Figure 2 In the grid 200 shown, the first transverse rib 211 in the first sub-region 261 has an inclination angle of θ1 relative to the Y-axis, referring to... Figure 3 The second transverse rib 212 in the second sub-region 262 has an inclination angle of θ2 relative to the Y-axis; the third transverse rib 213 in the third sub-region 263 has an inclination angle of θ3 relative to the Y-axis, as shown in the reference. Figure 5 The angles θ1, θ2, and θ3 are not the same.

[0071] The fan is an axial fan. The air is accelerated after passing through the axial fan and blown out in a spiral shape. The inclination angle of the windward surface 214 of the horizontal ribs 210 in different sub-regions 260 is different to conform to the spiral airflow, reduce the resistance of the grille 200 to the airflow, and ensure the air volume of the outdoor unit.

[0072] In some embodiments of this application, reference is made to Figure 2 and Figure 3The grille 200 includes a first sub-region 261, within which a plurality of first transverse ribs 211 are provided. The windward surface 214 of the first transverse ribs 211 extends obliquely toward the top of the housing 100. In other words, the windward surface 214 of the first transverse ribs 211 is inclined upward, and the upward inclination angle of the windward surface 214 of the first transverse ribs 211 is denoted as θ1.

[0073] Reference Figure 2 and Figure 5 The grille 200 also includes a third sub-region 263, within which a plurality of third transverse ribs 213 are provided. The windward surface 214 of the third transverse ribs 213 extends obliquely toward the bottom of the housing 100. In other words, the windward surface 214 of the third transverse ribs 213 is inclined upward, and the downward inclination angle of the windward surface 214 of the third transverse ribs 213 is denoted as θ3.

[0074] The first sub-region 261 and the third sub-region 263 are arranged to the left and right along the width direction W2 of the grille 200. The first transverse rib 211 and the third transverse rib 213 are arranged to the left and right along the width direction W2 of the grille 200. The windward side 214 of the first transverse rib 211 and the windward side 214 of the third transverse rib 213 are inclined in opposite directions.

[0075] The fan is an axial flow fan. After passing through the axial flow fan, the air is accelerated and blown out in a spiral shape. The windward surface 214 of the first horizontal rib 211 and the windward surface 214 of the third horizontal rib 213 are inclined in opposite directions. The windward surface 214 of the first horizontal rib 211 is inclined upward, and the windward surface 214 of the third horizontal rib 213 is inclined downward, so as to conform to the spiral air outlet, reduce the resistance of the grille 200 to the air outlet airflow, and ensure the air volume of the outdoor unit.

[0076] In some embodiments of this application, reference is made to Figure 2 and Figure 4 The grille 200 also includes a second sub-region 262. The first sub-region 261, the second sub-region 262 and the third sub-region 263 are arranged sequentially along the width direction of the grille 200. The second sub-region 262 is located between the first sub-region 261 and the third sub-region 263.

[0077] Multiple second transverse ribs 212 are provided within the second sub-region 262, and the second transverse ribs 212 extend along the air outlet direction of the outdoor unit of the air conditioner. In other words, the second transverse ribs 212 extend along the Y-axis, the windward surface 214 of the second transverse ribs 212 is not inclined, and the inclination angle θ2 of the second transverse ribs 212 relative to the Y-axis is 0°.

[0078] The grille 200 includes three sub-regions 260 arranged sequentially on the left, middle and right. The first horizontal rib 211 in the first sub-region 261 on the left is inclined upward on the windward side, the second horizontal rib 212 in the second sub-region 262 in the middle extends horizontally, and the third horizontal rib 213 in the third sub-region 263 on the right is inclined downward on the windward side. In this way, it can further effectively conform to the spiral air outlet of the outdoor unit, reduce the resistance of the grille 200 to the air outlet airflow, and ensure the air volume of the outdoor unit.

[0079] In some embodiments of this application, reference is made to Figure 3 The windward surface 214 of the first transverse rib 211 is inclined at 10° to 50° toward the top of the housing 100. In other words, the first transverse rib 211 is inclined upward, and the inclination angle θ1 ranges from 10° to 50°.

[0080] Reference Figure 5 The windward side 214 of the third transverse rib 213 is inclined at 10° to 50° towards the bottom of the housing 100. In other words, the third transverse rib 213 is inclined downward, and the inclination angle θ3 ranges from 10° to 50°.

[0081] The range of tilt angles is set to minimize the resistance of the grille 200 to airflow and ensure air volume.

[0082] In some embodiments of this application, reference is made to Figure 3 The first transverse rib 211 includes a first windward section 2111 and a first air outlet section 2112. The first windward section 2111 and the first air outlet section 2112 are arranged sequentially along the air outlet direction Y-axis. The first windward section 2111 extends obliquely toward the top of the housing 100, and the first air outlet section 2112 extends horizontally along the air outlet direction Y-axis.

[0083] In other words, the first horizontal rib 211 is not tilted throughout the entire structure, but only the first windward section 2111 tilts upward. While effectively reducing wind resistance, the horizontally extending first air outlet section 2112 ensures the horizontal air supply of the outdoor unit and guarantees the air supply distance.

[0084] In some embodiments of this application, reference is made to Figure 5 The third transverse rib 213 includes a third windward section 2131 and a third air outlet section 2132. The third windward section 2131 and the third air outlet section 2132 are arranged sequentially along the air outlet direction Y-axis. The third windward section 2131 extends obliquely toward the bottom of the housing 100, and the third air outlet section 2132 extends horizontally along the air outlet direction Y-axis.

[0085] In other words, the third horizontal rib 213 is not tilted throughout the entire structure, but only the third windward section 2131 tilts downward. While effectively reducing wind resistance, the horizontally extended third air outlet section 2132 ensures the horizontal air supply of the outdoor unit and guarantees the air supply distance.

[0086] In some embodiments of this application, reference is made to Figure 4 The longitudinal section of the transverse rib 210 along the height direction H2 of the grille 200 has a dimension of D. Along the air outlet direction Y-axis of the outdoor unit of the air conditioner, the value of D first increases and then decreases.

[0087] In other words, the longitudinal section of the transverse stiffener 210 is "dolphin-shaped". The longitudinal section of the transverse stiffener 210 is narrow on the windward and air outlet sides and wide in the middle. Using the fluid dynamics diagram, this helps to further reduce wind resistance.

[0088] In some embodiments of this application, reference is made to Figure 8 and Figure 9 , Figure 9 for Figure 8 Enlarged view of section F. A connecting part 230 is provided on the windward side of the grille 200. For example, the connecting part 230 is a hook. The hooks are located at the upper position of the grille 200, and multiple hooks are arranged at intervals along the width direction W2 of the grille 200. A corresponding latch is provided on the housing 100, and the grille 200 is pre-positioned on the housing 100 by the engagement between the hooks and the latches.

[0089] In some embodiments of this application, reference is made to Figure 7 , Figure 7 for Figure 2 Enlarged view of section E. The grille 200 is provided with mounting holes 240. The mounting holes 240 are located at a lower position on the grille 200, and multiple mounting holes 240 are arranged at intervals along the width direction W2 of the grille 200. The housing 100 is provided with corresponding screw holes, with the mounting holes 240 facing each other, allowing the grille 200 to be fastened to the housing 100 using screws.

[0090] The mounting hole 240 is located at the transverse rib 210. After the screw is driven into the mounting hole 240, the screw is embedded in the transverse rib 210, and the transverse rib 210 provides a shielding effect for the screw.

[0091] In some embodiments of this application, Figure 10 This is a partial structural diagram of the transverse rib 210. Along the width direction W2 of the grille 200, the extension length of the transverse rib 210 along the air outlet direction Y-axis is not uniform. The windward end face of the transverse rib 210 is flush, while the air outlet end face of the transverse rib 210 has a wavy structure, making the grille 200 more aesthetically pleasing.

[0092] For example, refer to Figure 10The transverse rib 210 includes a first transverse rib 2151 and a second transverse rib 2152 arranged at intervals along the length of the transverse rib 210. The extension length of the first transverse rib 2151 along the Y-axis of the air outlet direction is denoted as h1, and the extension length of the second transverse rib 2152 along the Y-axis of the air outlet direction is denoted as h2, where h1 > h2.

[0093] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0094] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
