Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to an air conditioning chassis structure, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] In the related art, the heat exchanger of the air conditioner outdoor unit is generally placed directly on the chassis, and the chassis is provided with drainage holes for drainage. However, when the fan of the air conditioner outdoor unit is working, the drainage holes at the bottom of the heat exchanger are prone to form a large negative pressure, causing the condensed water inside the machine to spread along the air flow direction, and the discharge of the condensed water is blocked. The condensed water that cannot be discharged in time will gradually freeze inside the chassis and on the mesh cover, which will cause negative effects such as heat exchange damage, fan blade damage, and reduced air supply, affecting the operation of the air conditioner outdoor unit.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0058] In the related art, the heat exchanger of the air conditioner outdoor unit is generally placed directly on the chassis, and the chassis is provided with drainage holes for drainage. However, when the fan of the air conditioner outdoor unit is working, the drainage holes at the bottom of the heat exchanger are prone to form a large negative pressure, causing the condensed water inside the machine to spread along the air flow direction, and the discharge of the condensed water is blocked. The condensed water that cannot be discharged in time will gradually freeze inside the chassis and on the mesh cover, which will cause negative effects such as heat exchange damage, fan blade damage, and reduced air supply, affecting the operation of the air conditioner outdoor unit.

[0059] Reference Figure 1 In one aspect of the present application, an air conditioner is provided, the air conditioner comprises an air conditioner indoor unit (not shown in the figure) and an air conditioner outdoor unit 1000, the air conditioner indoor unit is installed indoors, and the air conditioner outdoor unit 1000 is connected to the air conditioner indoor unit through a pipeline. The air conditioner outdoor unit 1000 is responsible for cooling or heating, and transports refrigerant through the pipeline, and the refrigerant exchanges heat with the indoor air and the outdoor air respectively, and the air conditioner indoor unit is responsible for transporting cold air or hot air to the room to achieve the effect of cooling or heating.

[0060] On the other hand, the present application proposes an air conditioner outdoor unit 1000, referring to Figures 1 to 4 In the embodiment of the present application, the air conditioner outdoor unit 1000 includes an air conditioner chassis structure 100, and a heat exchanger 200, a fan 300, and a compressor (not shown in the figure) supported on the air conditioner chassis structure 100. The air conditioner chassis structure 100 forms the main frame of the air conditioner outdoor unit 1000, and the air conditioner chassis structure 100 can be made of metal material to improve the structural strength of the air conditioner chassis structure 100, so as to ensure the stability of supporting and installing the heat exchanger 200, the fan 300, and the compressor.

[0061] Combination Figure 5 , a refrigerant pipe 204 is arranged inside the heat exchanger. During the cooling process: the refrigerant flows from the compressor to the heat exchanger 200 of the air conditioner outdoor unit 1000 in turn, and then flows to the heat exchanger of the air conditioner indoor unit. At this time, the heat exchanger 200 of the air conditioner outdoor unit 1000 acts as a condenser to condense the high-temperature and high-pressure refrigerant from the compressor, and the heat exchanger of the indoor air conditioner acts as an evaporator, and heat exchanges between the low-temperature refrigerant and the indoor air, thereby outputting cold air, and then the refrigerant circulates back to the compressor. During the heating process: the refrigerant flows from the compressor to the heat exchanger of the air conditioner indoor unit in turn, and then flows to the heat exchanger 200 of the air conditioner outdoor unit 1000. At this time, the high-temperature refrigerant from the compressor exchanges heat with the indoor air and outputs warm air. At this time, the heat exchanger of the air conditioner indoor unit is a condenser, and the heat exchanger 200 of the air conditioner outdoor unit 1000 acts as an evaporator, and then the refrigerant circulates back to the compressor. The air inlet side 200A of the heat exchanger 200 of the air conditioner outdoor unit 1000 is located outside the air conditioner outdoor unit 1000, and the air outlet side 200B of the heat exchanger 200 is located inside the air conditioner outdoor unit 1000. In addition, the air conditioner outdoor unit 1000 further includes a top cover 400 and a vertically extending enclosure 500, so that the air conditioner chassis structure 100 cooperates with the enclosure 500 and the top cover 400 to form an accommodating space, so that the heat exchanger 200, the fan 300 and the compressor are all located in the accommodating space. The enclosure 500 is provided with an air outlet 501, and the fan 300 may be an axial flow fan 300, which is fixed on the air conditioner chassis structure 100 by a bracket. The axial flow fan 300 is located on the air outlet side 200B of the heat exchanger 200, so that the fan 300 rotates so that the external air flow can pass through the air inlet side 200A of the heat exchanger 200 through the air outlet side 200B for heat exchange, and then be blown out from the air outlet 501 to the outdoor environment.

[0062] In order to enable the condensed water generated by the heat exchanger 200 of the air conditioner outdoor unit 1000 to be discharged smoothly during the use of the air conditioner outdoor unit 1000, refer to Figure 3 , Figure 4 , Figure 6 as well as Figure 7 On the other hand, the present application provides an air conditioner chassis structure 100, which is supported below a heat exchanger 200. The air conditioner chassis structure 100 includes a chassis body 10, which is provided with a drainage hole 10A below the heat exchanger 200. The drainage hole 10A penetrates two opposite surfaces of the chassis body 10 in the thickness direction. The drainage hole 10A is at least partially exposed on the air inlet side 200A of the heat exchanger 200 and communicates with the external space of the air inlet side 200A of the heat exchanger 200.

[0063] It should be noted that after the heat exchanger 200 is placed on the disk body 10, the heat exchanger 200 is fixed to the disk body 10 by means of buckles or screws to ensure the stability of the bottom of the disk body 10 supporting the heat exchanger 200. The drainage holes 10A penetrate the two opposite surfaces in the thickness direction of the disk body 10, so that the condensed water generated during the operation of the heat exchanger 200 flows to the bottom of the heat exchanger 200 under the action of gravity and then is discharged to the outside through the drainage holes 10A of the disk body 10. The opening shape of the drainage holes 10A can be arranged in a strip shape along the extension direction of the heat exchanger 200. Of course, the drainage holes 10A can also be regular shapes such as circular or rectangular, so as to be regularly arranged on the disk body 10.

[0064] Reference Figure 3 and Figure 5 Optionally, the air conditioner chassis structure 100 further includes a plurality of support legs 50, the support legs 50 being connected to the surface of the disk body 10 away from the heat exchanger 200, and the plurality of support legs 50 being staggered with the drainage hole 10A. The plurality of support legs 50 can be connected to the surface of the disk body 10 away from the heat exchanger 200 by means of screws or buckles, and the support legs 50 can be placed on the external support surface, so that there is a gap between the disk body 10 and the external support surface, and the support legs 50 are staggered with the drainage hole 10A, thereby facilitating the smoothness of drainage of the drainage hole 10A. In addition, a support leg drainage hole 51 is also provided on the support leg 50, and the support leg drainage hole 51 passes through the two relative surfaces in the thickness direction, so as to facilitate the flow of accumulated water above the support leg 50 to the external support surface.

[0065] Based on the air conditioner chassis structure 100 of the embodiment of the present application, by making the drain hole 10A of the chassis body 10 at least partially exposed on the air inlet side 200A of the heat exchanger 200, the drain hole 10A is connected with the space on the air inlet side 200A of the heat exchanger 200. In this way, since the drain hole 10A is connected with the outside air on the air inlet side 200A of the condenser, the air flowability at the bottom of the heat exchanger 200 is better, and it is not easy to form a large negative pressure at the drain hole 10A, which greatly reduces the difficulty of draining condensed water at the drain hole 10A, ensures the drainage efficiency of the drain hole 10A, and prevents the external accumulated water from being sucked back into the air conditioner chassis structure 100 through the drain hole 10A, and makes it easy for outsiders to observe the blockage of the drain hole 10A, ensuring the stable drainage function of the drain hole 10A, so as to improve the technical problem of poor drainage of the drain hole 10A.

[0066] Reference Figure 4 and Figure 6Optionally, the drain hole 10A includes a first hole portion 10a and a second hole portion 10b that are connected. The first hole portion 10a is located within the projection range of the heat exchanger 200 on the disk body 10, and the second hole portion 10b is exposed on the air inlet side 200A of the heat exchanger 200. The opening area of ​​the first hole portion 10a is larger than the opening area of ​​the second hole portion 10b. In this way, the first hole portion 10a is located within the projection range of the heat exchanger 200 on the disk body 10, that is, the first hole portion 10a is located directly below the heat exchanger 200. Even if the condensed water and other water vapor in the drain hole 10A are blown up by the external airflow, since the heat exchanger 200 is located on the first hole portion 10a of the drain hole 10A, the water vapor will be blocked on the bottom of the heat exchanger 200 and gradually drip, effectively preventing the water vapor from being blown into the shell from the drain hole 10A and contacting the fan 300 and other components. The second hole portion 10b is exposed on the air inlet side 200A of the heat exchanger 200 to communicate with the space on the air inlet side 200A of the heat exchanger 200. By making the opening area of ​​the first hole portion 10a larger than the opening area of ​​the second hole portion 10b, the facing area between the drainage hole 10A and the bottom of the heat exchanger 200 is increased, thereby further improving the drainage efficiency of the drainage hole 10A for the condensed water of the heat exchanger 200.

[0067] Reference Figure 4 and Figure 7 Optionally, the surface of the disk body 10 facing the heat exchanger 200 is concavely formed into a groove 111, the heat exchanger 200 is arranged in the groove of the groove 111, and the drainage hole 10A is opened at the bottom of the groove 111. It should be noted that, Figure 7 The dotted outline in the figure is the outline of the heat exchanger 200. The groove 111 is located at the edge of the disk body 10, so that the heat exchanger 200 is also located at the edge of the disk body 10, so that the external airflow passes through the air inlet side 200A of the heat exchanger 200. By forming the groove 111 on the disk body 10 to install the heat exchanger 200, not only the installation efficiency of the heat exchanger 200 can be improved, but also the condensed water of the heat exchanger 200 can be effectively reduced from flowing to other positions of the disk body 10.

[0068] Reference Figure 4 , Figure 7 as well as Figure 8 Optionally, the groove 111 includes a supporting groove 1111 and a drainage groove 1112 that are connected, the groove bottom of the supporting groove 1111 and the groove bottom of the drainage groove 1112 are arranged in a stepped manner, and the groove bottom of the supporting groove 1111 is located above the groove bottom of the drainage groove 1112. The bottom of the heat exchanger 200 is supported on the groove bottom surface of the supporting groove 1111, and the groove bottom of the drainage groove 1112 is provided with a drainage hole 10A.

[0069] It should be noted that the bottom surface of the support groove 1111 in this embodiment is Figure 4 , Figure 6 as well as Figure 7 , Fig.13 as well as Fig.14 As shown in the figure, the first pattern P1 is filled in the support groove 1111, and the first pattern P1 is in a rectangular array block shape. The bottom surface of the support groove 1111 is arranged in a plane, so as to ensure the stability of the heat exchanger 200 placed at the support groove 1111. By making the bottom of the support groove 1111 above the bottom of the drainage groove 1112, the plane of the plate body 10 where the drainage hole 10A is opened is located below the bottom support surface of the plate body 10 at the heat exchanger 200. In this way, when there is too much condensed water or the drainage hole 10A is blocked and causes water accumulation, the accumulated water will remain in the drainage groove 1112 to avoid contacting the bottom of the heat exchanger 200 for a long time.

[0070] Furthermore, the drainage groove 1112 is exposed at the air inlet side 200A of the heat exchanger 200 and is connected to the space at the air inlet side 200A of the heat exchanger 200. The drainage groove 1112 is connected to the space at the air inlet side 200A of the heat exchanger 200, so that the drainage groove 1112 is not easy to generate negative pressure, thereby ensuring smooth water flow in the drainage groove 1112 and reducing the risk of blockage by residues such as leaves and dirt during subsequent use.

[0071] Reference Figure 4 and Figure 7 Optionally, a plurality of drainage holes 10A are provided at the bottom of the drainage groove 1112, and the plurality of drainage holes 10A are arranged at intervals along the extension direction of the drainage groove 1112. The plurality of drainage holes 10A are connected through the drainage groove 1112, so that even when one of the drainage holes 10A is blocked, condensed water can flow to other drainage holes 10A through the drainage groove 1112, thereby preventing local drainage failure and ensuring drainage efficiency.

[0072] Reference Figure 8 Optionally, the distance between the bottom of the drain groove 1112 and the bottom of the support groove 1111 is greater than 2 mm. In order to take into account the later installation environment of the air-conditioning outdoor unit 1000, it is necessary to control the discharge position of the condensed water of the outdoor air conditioner, so that some of the drain holes 10A are sealed by installing silicone plugs. In order to prevent the silicone plug from damaging the condenser, the distance between the bottom of the drain groove 1112 and the bottom of the support groove 1111 is greater than 2 mm, so that the gap between the plane of the drain hole 10A of the disk body 10 and the bottom support surface of the disk body 10 of the heat exchanger 200 is larger, thereby avoiding the subsequent installation of the silicone plug from affecting the heat exchanger 200 and ensuring the normal use of the heat exchanger 200.

[0073] Reference Figures 2 to 4 ,as well as Figure 7Optionally, the heat exchanger 200 includes a first heat exchange part 201 and a second heat exchange part 202 arranged at an angle, and the drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B, the first sub-groove 111A is located below the first heat exchange part 201, and the first sub-groove 111A extends along the length direction of the first heat exchange part 201, the second sub-groove 111B is located below the second heat exchange part 202, and the second sub-groove 111B extends along the length direction of the second heat exchange part 202, and the bottom of the first sub-groove 111A and the bottom of the second sub-groove 111B are both provided with drainage holes 10A. The first heat exchange part 201 and the second heat exchange part 202 can be arranged at a right angle, so as to increase the contact area between the air inlet side 200A of the heat exchange part and the outside world. By providing the first sub-groove 111A corresponding to the first heat exchange part 201 and the second sub-groove 111B corresponding to the second heat exchange part 202 , the condensed water generated by the first heat exchange part 201 and the second heat exchange part 202 can be discharged respectively to improve the drainage efficiency.

[0074] Combined with reference Figure 4 , Figures 7 to 11 In one embodiment, a drainage groove 1112 is formed on the surface of the disk body 10 facing the heat exchanger 200, and the drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B that are connected. The first sub-groove 111A and / or the second sub-groove 111B include a first groove section 10A and a second groove section 111b that are connected alternately in sequence, and a drainage hole 10A is opened at the groove bottom of the first groove section 10A, and the size of the second groove section 111b in the direction from the air inlet side 200A of the heat exchanger 200 to the air outlet side 200B is smaller than the size of the first groove section 10A in the direction from the air inlet side 200A of the heat exchanger 200 to the air outlet side 200B.

[0075] In this way, the opening spacing of the first groove section 10A with the drainage hole 10A is larger than that of the second groove section 111b without the drainage hole 10A, thereby ensuring the drainage efficiency and the contact area between the plate body and the heat exchanger 200, thereby ensuring the stability of the chassis supporting the heat exchanger 200.

[0076] Reference Figure 1 , Figure 2 , Figure 4 as well as Fig.13 Optionally, the disk body 10 includes a bottom plate 11 and a partition plate 12 connected to the bottom plate 11, the bottom plate 11 includes a fan area NA and a mechanical area AA located on opposite sides of the partition plate 12, and a heat exchange area BA located at the edge of the fan area NA, the surface of the heat exchange area BA facing the heat exchanger 200 is recessed to form a groove 111, the drainage hole 10A is arranged at the bottom of the groove 111, the fan area NA includes a junction adjacent to the groove 111, and the groove 111 is recessed relative to the junction.

[0077] The partition plate 12 may be provided in the form of a boss, and the partition plate 12 is used to install the partition plate 600, and the partition plate 600 may be fixed to the partition plate 12 by screws or welding, so as to partition the space in the air conditioner outdoor unit 1000. It can be understood that the fan area NA is used to install the fan 300, the mechanical area AA may be used to install the compressor, and the heat exchange area BA is provided with a groove 111 for installing the heat exchanger 200. The fan area NA is provided with a boss for installing the bracket of the fan 300, so as to improve the support strength of the bottom plate 11 for the fan 300.

[0078] Furthermore, in conjunction with reference Fig.14 The bottom plate 11 is provided with a first water outlet hole 112, which penetrates two opposite surfaces in the thickness direction of the bottom plate 11 and is located on the side of the heat exchange area BA close to the mechanical area AA. The bottom plate 11 is provided with a first guide groove 113, which extends from the mechanical area AA to the heat exchange area BA and is connected to the first water outlet hole 112. It should be noted that the bottom surface of the first guide groove 113 in this embodiment is Fig.13 and Fig.14 As shown in the figure, the second pattern P2 is filled in the heat exchange area BA of the bottom plate 11, and the bottom surface of the groove 111 is lower than the bottom surface of the first guide groove 113, that is, the plane of the heat exchange area BA of the bottom plate 11 is lower than the plane of the bottom plate 11 in the fan area NA, so that the condensed water and other accumulated water in the fan area NA will easily flow to the groove 111 under the action of gravity and then flow out from the drainage hole 10A. By opening a first water outlet 112 in the heat exchange area BA of the bottom plate 11, and setting a first guide groove 113 extending from the mechanical area AA to the heat exchange area BA, and connecting with the first water outlet 112, the condensed water and other accumulated water in the mechanical area AA can be discharged from the first water outlet 112 along the first guide groove 113, so as to avoid opening a through hole in the mechanical area AA for drainage, and prevent foreign objects such as insects from easily entering the mechanical area AA to damage equipment such as compressors.

[0079] Furthermore, the bottom surface of the first guide groove 113 gradually decreases toward the extension direction of the first water outlet 112. This can further increase the flow rate of the accumulated water in the first guide groove 113 to prevent the accumulated water such as condensed water from staying in the mechanical area AA of the disk body 10 for too long.

[0080] Reference Figure 4 and Fig.13 Optionally, the first guide groove 113 extends in a circumferentially zigzag manner in the mechanical area AA, so as to collect condensed water and other accumulated water at various positions of the mechanical area AA.

[0081] Combined with reference Figure 4 , Figure 5 as well as Fig.14Optionally, the bottom plate 11 is provided with a recess 114 at the bottom of the support groove 1111, the recess 114 is located between the first water outlet 112 and the mechanical area AA, and the opposite ends of the recess 114 are connected to the first guide groove 113. The recess 114 is formed at the bottom of the support groove 1111 to connect the first guide groove 113, thereby increasing the flow rate from the first guide groove 113 to the first water outlet 112, so as to improve the drainage efficiency of the condensed water and other accumulated water in the mechanical area AA.

[0082] Optionally, refer to Fig.13 and Fig.14 A drainage groove 1112 is formed on the surface of the disk body 10 facing the heat exchanger 200, and the drainage groove 1112 includes a first sub-groove 111A and a second sub-groove 111B that are connected. The second sub-groove 111B is connected to the first water outlet 112. In this way, the condensed water and other accumulated water in the second sub-groove 111B can also be discharged from the first water outlet 112. When the first water outlet 112 is blocked, the water flow of the first guide groove 113 can also flow to the second sub-groove 111B and be discharged from the drainage hole 10A of the second sub-groove 111B, thereby ensuring the overall drainage efficiency and smoothness of the bottom plate 11.

[0083] Reference Figure 4 , Fig.13 and Fig.15 Optionally, the bottom plate 11 is also provided with a second water outlet hole 115, and the second water outlet hole 115 penetrates the two relative surfaces in the thickness direction of the bottom plate 11, and the second water outlet hole 115 is located below the junction of the first heat exchange part 201 and the second heat exchange part 202. The heat exchange area BA is also provided with a second guide groove 117 connecting the fan area NA and the second water outlet hole 115. Among them, the second water outlet hole 115 can not only be used to discharge the condensed water at the junction of the first heat exchange part 201 and the second heat exchange part 202, but also guide the condensed water of the fan area NA to the second water outlet hole 115 for discharge through the second guide groove 117. In addition, the bottom surface of the second guide groove 117 gradually decreases toward the extension direction of the second water outlet hole 115. In this way, the flow rate of the condensed water guided to the second water outlet hole 115 can be further increased.

[0084] Furthermore, at least part of the second water outlet 115 is exposed at the air inlet side 200A of the heat exchanger 200 and communicates with the external space of the air inlet side 200A of the heat exchanger 200. In this way, it is not easy to form a large negative pressure at the second water outlet 115, which greatly reduces the difficulty of draining the condensed water at the second water outlet 115, ensures the drainage efficiency, and prevents the external accumulated water from being sucked back into the air conditioner chassis structure 100 through the second water outlet 115, and makes it easy for outsiders to observe the blockage of the drainage hole 10A.

[0085] Reference Figure 4 , Fig.12 as well as Fig.15 Furthermore, the bottom plate 11 is recessed at the bottom of the supporting groove 1111 to form a through groove 116, and the through groove 116 is connected to the second water outlet 115 and the first sub-groove 111A. In this way, the condensed water and other accumulated water in the first sub-groove 111A can also be discharged from the second water outlet 115. When the second water outlet 115 is blocked, the water flow of the second guide groove 117 can also flow to the first sub-groove 111A and be discharged from the drainage hole 10A of the first sub-groove 111A, thereby ensuring the overall drainage efficiency and smoothness of the bottom plate 11.

The contact portion 132 contacts the surface of the air inlet side 200A of the heat exchanger 200 to limit the position, so as to ensure the stability of the heat exchanger 200 after installation. The avoidance portion 133 is recessed along the direction away from the air inlet side 200A of the heat exchanger 200, so as to avoid blocking the drainage hole 10A, so as to ensure the stability of the spatial communication between the drainage hole 10A and the air inlet side 200A of the heat exchanger 200.

In this embodiment, a mounting hole 31 can be opened on the column 30, and a connecting hole 135 is correspondingly opened on the flange 13, and a connecting member such as a screw is sequentially passed through the mounting hole 31 and the connecting hole 135 for fixing. The column 30 can also be connected to the top cover 400 of the air conditioner outdoor unit 1000, so as to provide support and reduce the stress on the heat exchanger 200. At the same time, the column 30 extends to the junction of the first heat exchange part 201 and the second heat exchange part 202 and blocks the second water outlet 115, thereby preventing leaves or residues from clogging the second water outlet 115, thereby ensuring the normal drainage function of the second water outlet 115.

[0089] Optionally, in conjunction with reference Figure 2 , Figure 4 , Figure 8 , Fig. 9 as well as Fig.13 The air conditioner chassis structure 100 also includes an inner stopper 20, which is connected to the bottom plate 11 and abuts against the surface of the air outlet side 200B of the heat exchanger 200. The bottom plate 11 is formed with a fixing groove in the fan area NA.
