Description

Technical Field

[0001] This invention relates to the field of air conditioning drainage technology, and more particularly to a technical field of air conditioning drain pipe protection. Background Technology

[0002] In the field of refrigeration and air conditioning technology, drainage structures are installed at the bottom of large air conditioners or refrigeration units in order to reduce the internal temperature of air conditioners, dehumidify air conditioners, and reduce the safety hazards caused by the accumulation of microorganisms inside air conditioners.

[0003] However, the existing air conditioning unit's drainage structure is fixed at the bottom of the unit, causing the drain pipe to protrude outside the unit. This makes the drain pipe highly susceptible to damage during transportation or relocation before assembly. Furthermore, the exposed drain pipe in existing technology results in significant space occupancy and inconvenience during transport. In addition, in many cases where space is limited before assembling large air conditioners, or when they need to be used in conjunction with other equipment, this protruding structure often causes interference, greatly hindering assembly. During on-site assembly, destructive modifications to the air conditioning unit, or to any interfering spaces or objects, are often required to complete the assembly process. Summary of the Invention

[0004] Based on the above analysis, the present invention aims to provide a bottom drainage device for air conditioning units, which solves the problems of easy damage and inconvenience in placement and transportation caused by the exposed drainage pipes of existing large air conditioning units, and also solves the problem of limited assembly space during the assembly process.

[0005] The objective of this invention is mainly achieved through the following technical solutions:

[0006] An air conditioner box bottom drainage device includes a water pipe fixing plate disposed on the bottom plate of the box body, wherein the bottom plate of the box body and the water pipe fixing plate are elastically connected by an elastic component.

[0007] Furthermore, a circular first through hole is provided at the center of the water pipe fixing plate, and the first through hole is fixedly connected to one end of the water pipe.

[0008] Furthermore, the water pipe fixing plate is provided with a plurality of first holes, the first holes being circumferentially disposed on the outer periphery of the first through hole.

[0009] Furthermore, a pad is formed by recessing the bottom plate of the box at the position corresponding to the water pipe fixing plate.

[0010] Furthermore, a second through hole is provided in the middle of the pad, the second through hole and the first through hole are on the same vertical central axis, and the diameter of the second through hole is larger than the diameter of the first through hole.

[0011] Furthermore, the pad is provided with a plurality of second holes corresponding to the position of the first hole, and the second holes are circumferentially distributed around the outer periphery of the second through hole.

[0012] Furthermore, a sealing ring is provided so that its edge fits against the outer periphery of the pad.

[0013] Furthermore, a distance adjustment device is also provided, which includes a nut and a bolt, with the bolt passing through the first hole and the second hole.

[0014] Furthermore, by adjusting the distance adjustment device, a downward pressure perpendicular to the water pipe fixing plate is applied to the water pipe fixing plate, causing the elastic component to contract. The water pipe fixing plate and the water pipe move downward under the drive of the elastic component until the bottom surface of the water pipe fixing plate contacts the sealing ring on the pad, and the water pipe extends out from the second through hole.

[0015] Furthermore, after the bottom surface of the water pipe fixing plate contacts the sealing ring on the pad, the upper surface of the water pipe fixing plate is lower than the upper surface of the inner side wall of the box bottom plate and higher than the lower surface of the outer side wall of the box bottom plate.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0017] (1) The air conditioner box bottom drainage device of this application, which is easy to protect and install, supports the originally exposed drain pipe in the air conditioner box with elastic components, making the bottom of the entire air conditioner box flat. During the installation process, only the same space as the air conditioner is needed to complete the installation operation, thus avoiding the disadvantage of reserving installation space for the drain pipe at the bottom of the traditional air conditioner box.

[0018] (2) The drainage device at the bottom of the air conditioning unit of this application, which is easy to protect and install, supports the originally exposed drain pipe in the air conditioning unit with elastic components, so that the drain pipe can be protected inside the air conditioning unit and avoids the risk of the drain pipe being exposed and damaged.

[0019] (3) The drainage device at the bottom of the air conditioning unit of this application, which is easy to protect and install, supports the originally exposed drain pipe in the air conditioning unit with an elastic component, so that the drain pipe is retracted into the air conditioning unit. This structure makes the bottom plane of the air conditioning unit intact, avoids the disadvantages of any protruding setting, greatly reduces the space occupied by the entire air conditioning unit during transportation, and facilitates stacking and transportation.

[0020] (4) The bottom drainage device of the air conditioner box of this application, which is easy to protect and install, has a bolt for fixing and locking vertically inserted between the water pipe fixing plate and the bottom plate of the box in the uninstalled state, and a nut is screwed on the bolt head outside the bottom plate of the box. When installing the device, the water pipe fixing plate and the bottom plate of the box can be tightened by simply rotating the nut outside the air conditioner box, avoiding the problem of inconvenience for manual operation inside the box, and allowing the installer to perform the installation operation outside the bottom plate of the air conditioner box.

[0021] (5) The bottom drainage device of the air conditioning unit of this application, which is easy to protect and install, has a recessed pad formed at the position corresponding to the water pipe fixing plate on the bottom plate of the unit. After the device is installed, the upper surface of the pad is lower than the upper surface of the inner side wall of the bottom plate of the unit, and the bottom of the pad is higher than the lower surface of the outer side wall of the bottom plate of the unit. The structure of this combination is designed to allow the condensate inside the air conditioning unit to drain, thus preventing the accumulation of condensate at the bottom of the air conditioning unit.

[0022] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or may be learned by practicing the invention.

[0033] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0034] A specific embodiment of the present invention discloses a bottom drainage device for an air conditioning unit, including a water pipe fixing plate 2 disposed on the bottom plate 1 of the unit, wherein the bottom plate 1 of the unit and the water pipe fixing plate 2 are elastically connected by an elastic member 3.

[0035] Specifically, such as Figure 1 As shown, one end of the elastic component 3 is fixedly connected to the lower surface of the water pipe fixing plate 2, and the other end of the elastic component 3 is connected to the upper surface of the box bottom plate 1. The elastic component 3 can be a spring, and a corrosion-resistant and waterproof coating, such as a polyolefin or epoxy resin coating, is attached to the surface of the spring to achieve its waterproof, corrosion-resistant, and anti-aging functions.

[0036] Furthermore, such as Figure 2 The aforementioned air conditioner unit bottom drainage device features a first through hole 4 at the center of the water pipe fixing plate 2. This first through hole 4 is circular, and its lower edge is fixedly connected to the upper end of the water pipe 5, ensuring the lower end of the water pipe 5 is higher than the unit's bottom plate 1. This allows the entire water pipe 5 to be fully supported by the elastic component 3 on the unit's bottom plate 1 when not installed. The elastic component 3 supports the previously exposed water pipe 5 inside the air conditioner unit, protecting it from damage. Simultaneously, this design retracts the entire water pipe 5 inside the air conditioner unit, achieving a complete planar surface on the lower surface of the unit's bottom plate 1. This avoids the drawback of protruding water pipes on the lower surface of the unit's bottom plate 1, reducing the space occupied by the entire air conditioner component or unit during transportation and enabling stacked transport.

[0037] Furthermore, the water pipe fixing plate 2 is provided with four first holes 6 of the same diameter, which are arranged circumferentially around the first through hole 4, and the distance between the first holes 6 is equal. A total of four elastic members 3 are provided, which are arranged circumferentially at equal intervals around the first through hole 4, and the positions of the four first through holes 4 and the positions of the four elastic members 3 are staggered and spaced apart.

[0038] Furthermore, a recessed pad 8 is formed at the position corresponding to the water pipe fixing plate 2 on the bottom plate 1 of the housing. The upper surface of the pad 8 is lower than the upper surface of the inner side wall of the bottom plate 1, and the lower surface of the pad 8 is higher than the lower surface of the outer side wall of the bottom plate 1. This recessed structure is designed to allow condensate inside the air conditioning unit to drain, preventing condensate from accumulating at the bottom of the air conditioning unit.

[0039] Furthermore, such as Figure 3 As shown, the pad 8 has a second through hole 9 in the middle. The through hole is circular. The second through hole 9 and the first through hole 4 are on the same vertical central axis, and the diameter of the second through hole 9 is larger than the diameter of the first through hole 4.

[0040] Specifically, the difference between the radius of the second through hole 9 and the straight radius of the first through hole 4 is between 3 and 6 mm. The reason for this radius difference being greater than 3 mm is to allow the water pipe 5 to move flexibly through the second through hole 9 during the contraction of the elastic component 3; while the reason for this radius difference being less than 6 mm is to fix the water pipe 5 within the range of the second through hole 9, avoiding serious displacement of the water pipe 5 and causing serious deviation of the drain outlet.

[0041] Specifically, the pad 8 has four second holes 10 of the same diameter, which are circumferentially distributed around the second through hole 9, and the distance between the second holes 10 is equal. Each second hole 10 is on the same vertical central axis as the first hole 6, and the diameters of the two are equal, in order to achieve fixation during subsequent installation.

[0042] Furthermore, a distance adjustment device is also provided, which includes a nut 7 and a bolt 11. The bolt 11 passes through the first hole and the second hole. The water pipe fixing plate 2 can be raised or lowered by adjusting the distance between the bolt heads of the nut 7 and the bolt 11.

[0043] Furthermore, the bottom drainage device of the air conditioner unit also includes a sealing ring 13. The sealing ring 13 is concentrically circular, and its edge fits against the outer periphery of the pad 8. After installation, the sealing ring 13 is tightly pressed between the pad 8 and the water pipe fixing plate 2, forming a sealed structure between the pad 8 and the water pipe fixing plate 2. This structure prevents air conditioner condensate from flowing out of the gap between the pad 8 and the water pipe fixing plate 2, ensuring that the condensate can only be discharged from the inlet at the upper end of the water pipe 5 in the device, achieving a single path for condensate outflow. The sealing ring 13 can be made of silicone or rubber material, achieving a good sealing effect between the pad 8 and the water pipe fixing plate 2. It is removable, allowing for periodic replacement of the sealing ring and preventing leakage due to aging. After the bottom surface of the water pipe fixing plate 2 contacts the sealing ring 13 on the pad 8, the upper surface of the water pipe fixing plate 2 is lower than the upper surface of the inner side wall of the box bottom plate 1 and higher than the lower surface of the outer side wall of the box bottom plate 1, which facilitates the outflow of liquid in the air conditioning box.

[0044] The following is combined with Figure 1-7 The technical solution of the present invention will be described in more detail below:

[0045] Example 1

[0046] Specifically, such as Figure 1-4 As shown, a nut 7 of a bottom drainage device for an air conditioner unit is fixedly mounted on the upper surface of a water pipe fixing plate 2. The unit's bottom plate 1 is fixedly connected to the water pipe fixing plate 2 by bolts 11. The bolt head of the bolt 11 passes through the first hole 6 and the second hole 10 from the lower end of a pad 8. A washer 12 and a rubber ring 14 can be provided between the bolt 11 and the lower surface of the unit's bottom plate 1. After installation, the washer 12 contacts the lower surface of the pad 8, ensuring a level fastening surface. The rubber ring 14 is positioned between the washer 12 and the bolt 11, providing both a fastening function and shock resistance to the entire device, preventing the bolt 11 from falling off due to vibration during air conditioner use. Furthermore, to further enhance the shock resistance of this easy-to-protect and install bottom drainage device for the air conditioner unit, after installation, the portion of the bolt 11 protruding from the nut 7 is welded to the nut 7, achieving a dual shock-resistant effect.

[0047] A method for installing a bottom drainage device for an air conditioning unit is provided, following these steps:

[0048] S1: Apply a downward pressure perpendicular to the water pipe fixing plate 2 from above, causing the elastic component 3 to contract. At this time, the water pipe 5 fixed below the water pipe fixing plate 2 moves downward together with the water pipe fixing plate 2 under the drive of the elastic component 3, so that the water pipe 5 extends out of the outer end of the box bottom plate 1 from the second through hole 9 as it moves downward, until the bottom surface of the water pipe fixing plate 2 contacts the sealing ring 13 on the pad 8.

[0049] S2: Pass the bolt 11, which is fitted with washer 12 and rubber ring 14, through the first hole 6 and the second hole 10 from below the pad 8;

[0050] S3: Rotate the bolt head of the rotating bolt 11 so that it is screwed to the nut 7 fixed on the upper surface of the water pipe fixing plate 2 so that the bolt 11 passes through the nut 7. After installation, the upper surface of the water pipe fixing plate 2 is lower than the upper surface of the box bottom plate 1, so that it is a recessed structure after installation.

[0051] S4: Weld the protruding section of bolt 11 extending out of nut 7 to nut 7 for fixation. The installation of the device is now complete.

[0052] Example 2

[0053] Specifically, such as Figure 5-7 As shown, before installation, the bolt 11 of an air conditioner unit bottom drainage device passes through the first hole 6 and the second hole 10, vertically penetrating the bottom plate 1 of the unit and the water pipe fixing plate 2. The bolt head of the bolt 11 is fixed to the upper surface of the water pipe fixing plate 2, while the bolt head of the bolt 11 passes through the lower surface of the outer wall of the bottom plate 1. Before installation, the nut 7 is rotated to connect with the bolt 11 protruding outside the bottom plate 1, but no tightening operation is performed. That is, at this time, the entire water pipe 5 is still located above the bottom plate 1, supported by the elastic member 3 and the water pipe fixing plate 2.

[0054] Specifically, the design of this embodiment 2 provides dual protection for the water pipe in its uninstalled state. First, when the device is not installed, the water pipe 5, fixedly connected to the water pipe fixing plate 2, is supported by the elasticity of the elastic component 3, ensuring that the bottom of the water pipe 5 is higher than the lower surface of the box bottom plate 1. This means the water pipe 5 is hidden inside the box, preventing unnecessary impacts. Second, the bolts 11, vertically penetrating the first hole 6 and the second hole 10, limit the position of the water pipe 5 fixed to the water pipe fixing plate 2. The four bolts in different positions ensure that the water pipe 5 is confined to a fixed position, preventing the device from tipping over and being damaged during transportation.

[0055] Furthermore, the design of this embodiment 2 simplifies the installation process and facilitates manual operation, allowing installation to be achieved simply by tightening the external nut 7. Specifically, in the uninstalled state, the bolt 11 for fixing and locking is vertically inserted between the water pipe fixing plate 2 and the bottom plate 1 of the housing, and the nut 7 is screwed onto the bolt head outside the bottom plate 1 of the housing. During installation, the water pipe fixing plate 2 and the bottom plate 1 are tightened by simply rotating the nut 7 outside the air conditioner housing, avoiding the inconvenience of manual operation inside the housing and allowing installers to perform the installation operation from outside the bottom plate of the air conditioner housing.

[0056] Furthermore, a washer 12 and a rubber ring 14 can be provided between the nut 7 and the lower surface of the base plate 1 of the housing. After installation, the washer 12 contacts the lower surface of the pad 8, serving to level the fastening surface. The rubber ring 14 is placed between the washer 12 and the nut 7, which not only fastens the nut 7 after installation but also provides shock resistance for the entire device, preventing the nut 7 from falling off due to vibration during air conditioning use. In addition, to further enhance the shock resistance of this easy-to-protect and install air conditioning unit bottom drainage device, after installation, the portion of the nut 7 protruding from the base plate 1 is welded to the nut 7, achieving a double shock resistance effect.

[0057] A method for installing a bottom drainage device for an air conditioning unit is provided, following these steps:

[0058] S1: Rotate the nut 7 below the bottom of the box base plate 1. During the screw tightening process, the bolt fixed on the water pipe fixing plate 2 will move downward. At the same time, the water pipe fixing plate 2 will move downward along with the water pipe 5 fixed on it, and the elastic component 3 will be compressed.

[0059] S2: The water pipe fixing plate 2 descends to contact the sealing ring 13, and continues to rotate until the water pipe fixing plate 2 can no longer continue to descend and stops. At this time, the upper surface of the water pipe fixing plate 2 is lower than the upper surface of the inner side wall of the box bottom plate 1, so that it forms a recessed structure after installation.

[0060] S3: Weld the nut 7 to the bolt 11 and the lower surface of the box base plate 1 to fix the device. The installation of the device is now complete.

[0061] Example 3

[0062] As an alternative to the anti-vibration and anti-loosening solutions in Embodiments 1 and 2, a set of wedge-shaped grooves are evenly distributed around the circumference of the second hole 10 on the lower surface of the outer side wall of the box base plate 1. In Embodiment 1 or 2, a ratchet corresponding to the wedge-shaped groove is provided on the inner surface of the bolt head of the nut 7 or bolt 11 corresponding to the lower surface of the outer side wall of the box base plate 1. When the distance between the bolt heads of the nut 7 and bolt 11 is adjusted until the water pipe fixing plate 2 contacts and is fixed with the pad 8, and the bolt head of the nut 7 or bolt 11 can no longer be rotated, the wedge-shaped groove and the ratchet interfere with each other, so that the nut 7 or bolt 11 cannot be reversed. This ensures that the water pipe fixing plate 2 will not rebound due to the vibration of the air conditioner motor during use after the air conditioner is installed, thus ensuring the drainage effect.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
