Technical Field

[0001] This invention relates to the field of air outlet equipment technology, and in particular to an outdoor air conditioning unit, an air conditioner, and an air guide ring. Background Technology

[0002] The outdoor unit of an air conditioner is a crucial component, primarily responsible for outputting airflow through a fan housed within the casing. In existing technology, to save materials and simplify the structure, a mounting frame is directly stamped onto the panel, and the fan is directly fixed to this frame. However, due to limitations in the panel's sheet metal mold, the air guide ring and the mounting frame must be installed separately. When the air guide ring is installed onto the panel, a gap exists between them. When the fan is running, the high-speed airflow passing through this gap produces a whistling sound, increasing the overall noise level of the unit. Summary of the Invention

[0016] And / or, the width of the mounting bracket is W, the width of the guide groove is L2, and L2 = 0.2 ≤ L2 / w ≤ 0.5.

[0017] In one embodiment, the mounting bracket has a structural groove on the side opposite to the air outlet, and the covering is at least partially installed in the structural groove.

[0018] In one embodiment, the covering includes a mounting portion and a flow guide portion, wherein the mounting portion and the flow guide portion are connected along the edge of the air guide channel to the center.

[0019] The covering is sleeved outside the mounting frame, and the air guide includes an air guide surface facing away from the air outlet and a connecting seat facing the air outlet. The air guide is installed in the structural groove through the connecting seat.

[0020] In one embodiment, the air guide ring further includes a plurality of connectors;

[0046] In existing technology, to save materials and simplify the structure, the fixing frame is directly stamped onto the panel, and the fan is directly fixed to the fixing frame on the panel. However, due to the panel sheet metal mold, the air guide ring and the panel fixing frame need to be set separately. When the air guide ring is installed on the panel, there will be a connection gap between the air guide ring and the panel fixing frame. When the fan is running, the high-speed airflow blowing through this gap will produce a "whistling" sound, which will increase the noise of the whole machine.

[0047] This invention proposes an outdoor unit 100 for an air conditioner.

[0048] Please see Figure 1 In one embodiment of the present invention, the outdoor unit 100 of the air conditioner includes a housing 10, a fan, and an air guide ring 20. The housing 10 has an air outlet 11, and a mounting bracket 12 is provided at the air outlet 11. The fan is disposed on the mounting bracket 12, and the air guide ring 20 includes an air guide component 21 and a covering component 22. The air guide component 21 is disposed inside the housing 10 and has an air guide channel 212 communicating with the air outlet 11. The covering component 22 is disposed inside the air guide channel 212, and at least a portion of the covering component 22 covers the mounting bracket 12 along the air outlet direction of the air guide channel 212 to seal the gap between the air guide component 21 and the mounting bracket 12.

[0049] The technical solution of this invention involves opening an air outlet 11 on the housing 10 of the outdoor unit 10 of the air conditioner, and setting a mounting bracket 12 at the air outlet 11. The mounting bracket 12 is used for mounting the fan. This arrangement is to avoid affecting the use of the fan by using the mounting bracket 12 for fan mounting. In this embodiment, the mounting bracket 12 can be integrally cast with the housing 10, or the mounting bracket 12 can be installed on the housing 10 in a detachable manner later. There are no major limitations on this. In order to improve the fan's suction effect on the outside air and the effect of centralized discharge, in this embodiment, an air guide ring 20 is also provided inside the housing 10. The air guide ring 20 is located inside the housing 10 and at least partially sleeved on the outside of the fan. This makes the fan at least partially located within the air guide channel 212 of the air guide ring 20 to achieve the above-mentioned technical effect. In this embodiment, since the mounting bracket 12 is set at the air outlet 11 of the housing 10, and the air guide ring 20 also needs to be installed inside the housing 10, and the air guide ring 20 The air guide channel 212 of the air guide ring 20 is connected to the air outlet 11. Therefore, when the air guide ring 20 is installed inside the housing 10, there will be an installation gap between the air guide ring 20 and the mounting bracket 12. Since the air driven by the fan needs to first pass through the air guide channel 212 of the air guide ring 20 and then flow to the mounting bracket 12 before being discharged through the air outlet 11, the installation gap between the air guide ring 20 and the mounting bracket 12 will cause a "whistling" sound when the fan is running, as the high-speed airflow passes through this gap. This will cause the outdoor unit of the air conditioner to emit a whistling sound. The machine 100 generates significant noise during operation. To address this issue, in this embodiment, the air guide ring 20 includes an air guide component 21 and a covering component 22. The air guide component 21 has the aforementioned air guide channel 212, and the covering component 22 is disposed within the air guide channel 212. When the air guide component 21 is installed within the housing 10, the air guide channel 212 of the air guide component 21 is connected to the air outlet 11 of the housing 10. The covering component 22 at least partially covers the mounting frame 12 along the air outlet direction of the gas driven by the fan through the air guide channel 212.The gap between the air guide 21 and the mounting bracket 12 is sealed. This arrangement ensures that the gas flowing through the air guide channel 212 is discharged through the air outlet 11 after passing through the covering 22. Thus, the high-speed airflow will not leak out through the gap between the air guide 21 and the mounting bracket 12, and will not affect the aforementioned "whistling" sound. In this embodiment, the air guide 21 and the covering 22 can be integrally molded by injection molding, or they can be assembled later by splicing. No further limitations are imposed on this. This arrangement ensures that the airflow will be able to... When the mounting bracket 12 for installing the fan is positioned between the fan and the air outlet 11 of the housing 10, and an air guide ring 20 for guiding the fan is installed inside the housing 10, the air guide ring 20 can be covered by the covering member 22 to seal the gap between the air guide ring 20 and the mounting bracket 12. This prevents the airflow from exiting through the air guide channel 212 to the air outlet 11 from exiting through the gap between the air guide ring 20 and the mounting bracket 12, thereby improving the air guiding effect of the outdoor unit of the air conditioner while reducing the overall noise level.

[0050] In one embodiment, such as Figure 3As shown, the covering 22 includes a mounting part 221 and a flow guide part 222. The mounting part 221 and the flow guide part 222 are connected along the edge of the air guide channel 212 to the center. The mounting part 221 is used to be mounted on the mounting frame 12, and the flow guide part 222 is used to cover the side of the mounting frame 12 facing away from the air outlet 11. To further enhance the airflow guiding effect of the mounting bracket 12, in this embodiment, the covering 22 includes a mounting portion 221 and a guiding portion 222. The mounting portion 221 and the guiding portion 222 are connected along the extension direction from the edge to the center of the air guide channel 212, that is, the mounting portion 221 is close to the edge of the air guide channel 212. In this embodiment, the mounting portion 221 is sleeved at the connection between the mounting bracket 12 and the housing 10, thus sealing the gap that exists when the air guide 21 is directly inserted into the mounting bracket 12. The guiding portion 222 is used to cover the side of the mounting bracket 12 facing away from the air outlet 11. Since the airflow needs to pass through the mounting bracket 12 first and then be discharged through the air outlet 11, and the mounting bracket 12 may be flat or grooved on the side facing away from the air outlet 11 during manufacturing, this design is used to avoid the airflow directly impacting the surface of this side of the mounting bracket 12, which would cause uneven airflow. Therefore, a guide section 222 is provided to cover the mounting bracket 12 in the direction of airflow, so that the airflow can be discharged through the air outlet 11 after passing through the guide section 222. This achieves the function of guiding the airflow. Regarding the guide section 222, the guide section 222 can be a convex arc surface or a pointed cone surface in the direction of airflow. The specific setting of the guide section 222 is not limited. Of course, in this embodiment, the surface of the mounting part 221 at the connection between the mounting bracket 12 and the housing 10 in the direction of airflow can also be set in the same way as the guide section 222. This is not limited. With this setting, not only can the noise generated by the airflow being discharged through the installation gap between the air guide ring 20 and the mounting bracket 12 be avoided, but the airflow can also be prevented from directly impacting the mounting bracket 12, causing airflow instability and impact noise.

[0051] In one embodiment, such as Figure 2 As shown, the air guide portion 222 has an air guide surface 222a on the side opposite to the air outlet 11, and the air guide surface 222a is arc-shaped. In this embodiment, the surface of the air guide portion 222 opposite to the air outlet 11 is configured with reference to the convex arc surface described above, that is, an arc-shaped air guide surface 222a is formed. The air guide surface 222a configured in this way can guide the airflow when the airflow is flowing, thereby achieving the same function and effect as in the above embodiment.

[0052] In one embodiment, such as Figure 5 and 6As shown, the width of the mounting bracket 12 is W, and the radius of the air guide surface 222a is R, where R = 1 ≤ R / w ≤ 1.2. In this embodiment, considering that if the radius of the air guide surface 222a is too small, it will not be able to cover the entire mounting bracket 12, and if the radius is too large, it will increase the airflow resistance, the radius of the air guide surface 222a can be reasonably calculated by referring to the above formula. For example, assuming the width of the mounting bracket 12 is 2, then the radius of the air guide surface 222a is between 2 and 2.4. In this embodiment, the width of the mounting bracket 12 is defined as the width of the side of the mounting bracket 12 facing the airflow direction.

[0053] In one embodiment, such as Figure 4 and Figure 9 As shown, the mounting part 221 includes a first connecting plate 221a, a second connecting plate 221b, and a third connecting plate 221c. The first connecting plate 221a is disposed between the second connecting plate 221b and the third connecting plate 221c. The first connecting plate 221a, the second connecting plate 221b, and the third connecting plate 221c enclose a mounting cavity for covering the mounting frame 12. In this embodiment, the mounting part 221 includes a first connecting plate 221a, a second connecting plate 221b, and a third connecting plate 221c. The first connecting plate 221a is used to connect the second connecting plate 221b and the third connecting plate 221c. That is, the second connecting plate 221b and the third connecting plate 221c are respectively disposed on both sides of the first connecting plate 221a. The first connecting plate 221a, the second connecting plate 221b, and the third connecting plate 221c form a mounting cavity for covering the mounting frame 12. In this embodiment, the first connecting plate 221a is located in the airflow direction, so the first connecting plate 221a can be arc-shaped with reference to the air guide surface 222a in the above embodiment to achieve the same airflow guiding effect as in the above embodiment. In this embodiment, the first connecting plate 221a, the second connecting plate 221b, and the third connecting plate 221c can be integrally formed or assembled later. No further limitations are imposed on this.

[0054] In one embodiment, such as Figure 1 and Figure 9As shown, the guide section 222 has a guide groove 222b on the side opposite to the air outlet 11. Since front-mounting the fan significantly reduces the distance between the impeller and the air outlet 11, and since the impeller is the power source driving the airflow (and in this embodiment, the power source is also a noise source), to further reduce the flow resistance of the guide section 222 to the airflow and increase the distance between the guide section 222 and the noise source, in this embodiment, a guide groove 222b is provided on the side of the guide section 222 opposite to the air outlet 11; that is, a guide groove 222b is provided on the side of the guide section 222 facing the airflow direction. This arrangement allows the guide section 222... The guide groove 222b reduces airflow resistance and can, to some extent, increase the distance from the noise source, thereby reducing vortex noise. In this embodiment, the guide groove 222b can be set with reference to the air guide surface 222a of the guide section 222 in the above embodiment. Alternatively, the edge of the guide groove 222b can be chamfered to further enhance the airflow guiding effect. No further limitations are imposed on this. The guide groove 222b can also be set on the mounting section 221 in the above embodiment. No further limitations are imposed on this.

[0055] Specifically, there are multiple guide channels 222b, which are arranged at intervals along the extension direction of the guide section 222. To further achieve the above-mentioned effect, in this embodiment, multiple guide channels 222b are provided, which are arranged at intervals along the extension direction of the guide section 222, that is, arranged sequentially at intervals along the direction from the edge of the air guide channel 212 to the center. This arrangement can further achieve the above-mentioned technical effect, and the specific number of guide channels 222b is not limited.

[0056] More specifically, such as Figures 5 to 8As shown, the width of the mounting bracket 12 is W, and the depth of the guide groove 222b is S, where S = 0.1 ≤ S / w ≤ 0.2; and / or, the width of the mounting bracket 12 is W, and the distance between two adjacent guide grooves 222b is L1, where L1 = L1: 0.2 ≤ L1 / w ≤ 0.6; and / or, the width of the mounting bracket 12 is W, and the width of the guide groove 222b is L2, where L2 = 0.2 ≤ L2 / w ≤ 0.5. To further achieve the above effects, in this embodiment, the depth of the guide channel 222b is designed with reference to the width of the mounting bracket 12. For example, if the width of the mounting bracket 12 is 2, then the depth S of the guide channel 222b is 0.2 to 0.4. And / or, the spacing L1 between two adjacent guide channels 222b is also set with reference to the width of the mounting bracket 12 being 2, then L1 is 0.4 to 1.2. And / or, the width L2 of the guide channel 222b is also set with reference to the width of the mounting bracket 12 being 2, then L2 is 0.4 to 1. In this embodiment, according to... Figure 7 and Figure 8 As shown, the following data are two sets of data obtained by replacing only the air guide ring 20 with the same outdoor unit as the test object. The solid line represents the data measured with the air guide ring 20 installed in this embodiment, and the dashed line represents the data measured with the conventional air guide ring 20. According to the comparison of the two sets of data, it can be seen that the air guide ring 20 in this embodiment reduces the airflow at the groove of bracket 122, thus increasing the airflow at the same speed. At the same airflow of 2800, the power is reduced by 3.4W and the noise is reduced by 2.4dB, which significantly helps to improve the efficiency of the fan and reduce the noise of the air supply.

[0057] In this embodiment, the depth S of the guide groove 222b is defined as the distance of the guide groove 222b toward the airflow direction, and the width of the guide groove 222b is defined as the groove width of the guide groove 222b along the extension direction of the guide portion 222.

[0058] In one embodiment, such as Figure 6 As shown, the mounting bracket 12 has a structural groove 122a on the side opposite to the air outlet 11, and the covering 22 is at least partially installed in the structural groove 122a. In this embodiment, since the mounting bracket 12 and the housing 10 of the outdoor air conditioner are integrally injection molded, structural grooves 122a are inevitably formed on the mounting bracket 12 to facilitate demolding or to increase the structural strength of the mounting bracket 12 itself. In this embodiment, two structural grooves 122a are provided. The opening of one structural groove 122a faces the airflow direction, and the opening of the other structural groove 122a faces away from the airflow direction. Figure 6 As shown, the mounting bracket 12 configured in this way is not only easy to demold, but also has high structural strength and low manufacturing cost. In this embodiment, at least part of the covering 22 covers the inner or outer side of the structural groove 122a, and there are no further limitations on this.

[0059] In one embodiment, such as Figure 3 and Figure 6 As shown, the covering 22 includes a mounting portion 221 and a guide portion 222. The mounting portion 221 and the guide portion 222 are connected along the edge of the air guide channel 212 to the center. The covering 22 is sleeved on the mounting frame 12. The guide portion 222 includes an air guide surface 222a facing away from the air outlet 11 and a connecting seat 222c facing the air outlet 11. The guide portion 222 is installed on the structural groove 122a through the connecting seat 222c. To enable the covering 22 to better cover the structural groove 122a, in this embodiment, the covering 22 is consistent with the above embodiment, including a mounting portion 221 and a guide portion 222. The mounting portion 221 is as follows: Figure 3 As shown, the guide portion 222 is fitted at the connection between the mounting bracket 12 and the housing 10, and is used to cover the opening of the structural groove 122a facing the airflow direction. To further improve the stability of the guide portion 222 covering the structural groove 122a, in this embodiment, as shown... Figure 6 As shown, the flow guide 222 also includes a connecting seat 222c. The connecting seat 222c is located on the side of the flow guide 222 away from the airflow direction. The connecting seat 222c is used to install in the structural groove 122a. This can improve the stability of the flow guide 222 covering the mounting frame 12 and further improve the structural strength of the mounting frame 12. In this embodiment, the connecting seat 222c is composed of two connecting legs. Of course, the connecting seat 222c can also be supported by a solid connecting leg. There are no further limitations on this.

[0060] In one embodiment, such as Figure 1 and Figure 9 As shown, the air guide ring 20 also includes multiple connectors 223; the covering 22 is provided with multiple components, and each connector 223 is used to connect two adjacent coverings 22, so that multiple coverings 22 are connected in sequence. In this embodiment, since the mounting frame 12 forms multiple supports 122, multiple coverings 22 are also provided in this embodiment. In order to make the connection relationship between multiple coverings 22 more stable, multiple connectors 223 are provided in this embodiment. Each connector 223 is used to connect two adjacent coverings 22. In this embodiment, the connectors 223 are provided on the side of the air guide 222 away from the mounting part 221. Through this arrangement, multiple coverings 22 are connected in sequence through multiple connectors 223 and form a closure, which can improve the connection stability between multiple coverings 22.

[0061] Specifically, the mounting frame 12 includes a mounting base 121 and a bracket 122. One end of the bracket 122 is connected to the housing 10, and the other end is used to support the mounting base 121. The mounting base 121 is used for mounting the fan. The connector 223 is located between the mounting base 121 and the fan to seal the installation gap between them. In this embodiment, the mounting frame 12 includes a mounting base 121 and a bracket 122. One end of the bracket 122 is fixedly connected to the housing 10, and the other end is connected to the mounting base 121 to support the mounting base 121. In this embodiment, to achieve stable support for the mounting base 121, multiple brackets 122 are provided, and the multiple brackets 122 are arranged circumferentially around the mounting base 121. In this embodiment, as shown... Figure 1 As described above, the connector 223 used to connect the multiple coverings 22 is located on the mounting base 121 and extends along the edge of the mounting base 121. In this embodiment, the mounting base 121 is used for the installation of the fan, that is, the connector 223 is located between the fan and the mounting base 121. When the fan is installed on the mounting base 121, it can compress the connector 223 to make the multiple coverings 22 more stable. Secondly, the connector 223 can also act as a seal to seal the gap between the fan and the mounting base 121 so that the airflow can penetrate into the gap and produce a shadow. The material of the connector 223 can be a flexible material, a rigid material, or a mixture of flexible and rigid materials. No specific limitation is made in this regard.

[0063] In one embodiment, such as Figure 9As shown, the air guide 21 has a flange 211 around one end away from the air outlet 11, and the diameter of the flange 211 gradually decreases along the air outlet direction of the air guide channel 212; and / or, the air guide 21 includes a connecting part 213, which is disposed on the outer wall of the air guide 21 and is used to connect with the housing 10. In this embodiment, the end of the air guide 21 facing away from the air outlet 11 is provided with a flange 211. The diameter of the flange 211 gradually decreases along the air outlet direction of the air guide channel 212. The flange 211 can improve the flow of outside air into the air guide channel 212 of the air guide 21 under the drive of the fan, and then discharge through the air outlet 11 under the drive of the fan. This arrangement can improve the power of the fan. In this embodiment, the air guide 21 also includes a connecting part 213. The connecting part 213 is provided on the outer wall of the air guide 21, or on the flange 211, or is connected to both the outer wall of the air guide 21 and the flange 211.

[0064] The present invention also proposes an air conditioner, which includes the above-mentioned outdoor unit 100. The specific structure of the outdoor unit 100 is as described in the above embodiments. Since the air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0065] The present invention also proposes an air guide ring 20, including an air guide component 21 and a covering component 22. The air guide component 21 has an air guide channel 212, and the covering component 22 is disposed within the air guide channel 212. At least a portion of the covering component 22 covers the external structure along the air outlet direction of the air guide channel 212 to seal the installation gap between the air guide component 21 and the external structure. Figure 9As shown, in this embodiment of the invention, the air guide ring 20 includes an air guide component 21 and a covering component 22. When the air guide component 21 is installed on an external structure, the covering component 22, which is disposed in the air guide channel 212 of the air guide component 21, covers the side of the external structure facing the flow direction of the airflow through the air guide channel 212. When the airflow flows through the outlet of the air guide channel 212, the airflow will not come into contact with the external structure, but will be discharged through the covering component 22 installed at the outlet of the air guide. Since the covering component 22 can effectively seal the gap between the air guide component 21 and the external structure, it can prevent high-speed airflow from flowing through the gap between the air guide component 21 and the external structure and generating wind noise. In addition, the covering component 22 can also guide the airflow flowing through it. Thus, the air guiding effect of the air guide ring 20 can be improved while achieving the purpose of noise reduction.

[0066] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
