The water pump assembly comprises a water pump and a float switch, and the float switch is used to monitor the water level in the water pan. When the water level exceeds a certain height, the condensate water is pumped out by the water pump.

[0003] In the prior art, a maintenance opening is arranged on the ceiling machine to maintain the water pump assembly. However, in order to save the space of the ceiling machine, the size of the maintenance opening is usually small, which is not conducive to the maintenance personnel's hand or maintenance tool to enter the interior of the ceiling machine to maintain the water pump assembly. SUMMARY

[0004] Therefore, the present application aims to provide a shell structure and a ceiling machine. The shell structure has a gap, a bracket is detachably arranged at the gap, and a water pump assembly is arranged on the bracket. The maintenance personnel only needs to detach the bracket to realize the disassembly of the water pump assembly, which is convenient for the maintenance personnel to disassemble and maintain the water pump assembly outside the ceiling machine, and reduces the maintenance difficulty and cost.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present application is as follows:

The water pump assembly is arranged on the bracket, and the shell comprises a bottom plate and a surrounding plate arranged on the outer periphery of the bottom plate. The surrounding plate has a gap, and the bracket is detachably arranged at the gap to block the gap. The gap is blocked by the bracket to prevent the gap from affecting the air inlet and outlet of the ceiling machine. Since the water pump assembly is arranged on the bracket, and the bracket is detachable, the maintenance personnel only needs to detach the bracket to realize the disassembly of the water pump assembly, which is convenient for the maintenance personnel to disassemble and maintain the water pump assembly outside the ceiling machine, and reduces the maintenance difficulty and cost.

[0007] Further, the water pump assembly comprises at least one of a water pump and a float switch, the support comprises a first support table, a second support table and a baffle, the baffle blocks the gap, the first support table and the second support table are arranged on the inner side of the gap, the water pump is arranged on the first support table, and the float switch is arranged on the second support table. The water pump is installed by using the first support table, and the float switch is installed by using the second support table, so that the layout of the water pump assembly is clearer and more reasonable, the water pump and the float switch are prevented from interfering with each other, and it is convenient for maintenance personnel to better distinguish and observe each component of the water pump assembly.

[0008] Further, the baffle is provided with a drain pipe water nozzle, the water pump comprises a water inlet, a drain outlet and a drain pipe, one end of the drain pipe is communicated with the drain outlet, and the other end is communicated with the drain pipe water nozzle.

The detachable connection facilitates the disassembly or assembly of the support.

[0011] Further, the valve plate is provided with a first opening, the baffle is provided with a second opening, and the first opening and the second opening cooperate to form the pipeline through hole. By the opening mode of the valve plate and the baffle, not only the raw materials can be saved and the bearing of the support can be reduced, but also the pipeline and / or the wire harness of the ceiling machine can pass through the upper pipeline through hole and the lower pipeline through hole formed by the valve plate and the support, so that the layout of the pipeline or the wire harness is facilitated, the pipeline and the wire harness of the ceiling machine are regularized, and the structural compactness of the ceiling machine is improved.

DETAILED DESCRIPTION

[0032] The present application will be described in detail below with reference to the accompanying drawings and embodiments. The embodiments described in the present application are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0033] It should be noted that the terms "upper," "lower," "left," "right," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0034] Example 1

[0035] like Figures 1-5 The illustrated housing structure includes a housing 1, a water pump assembly, and a bracket 2, with the water pump assembly mounted on the bracket 2. The housing structure is mounted on the ceiling-mounted air conditioning unit (CMU) to house and protect its components, preventing collisions with other objects and improving reliability during transportation, installation, and use. In cooling mode, the CMU produces condensate, which the water pump assembly promptly drains to ensure safe operation and prevent disruption to normal function. The bracket 2 supports and mounts the water pump assembly. The housing 1 includes a base plate 11 and a surrounding plate 12. The surrounding plate 12 has a notch 13, which the bracket 2 is detachably positioned at and seals, preventing obstruction of airflow and maintaining the integrity and aesthetics of the housing structure. Because the water pump assembly is mounted on the bracket 2, and the bracket 2 is detachable, the water pump assembly can be exposed to the outside view without being obstructed by other CMU components, allowing maintenance personnel to more directly observe its condition. Simultaneously, by using a notch 13 in the enclosure 12 and mounting the water pump assembly at the notch 13, there is no need to provide an access port on the housing structure. Maintenance personnel do not need to extend their hands or tools into the narrow access port, providing them with greater operating space. Maintenance personnel can disassemble the water pump assembly simply by removing the bracket 2, facilitating disassembly, assembly, and maintenance of the water pump assembly from the outside of the ceiling-mounted unit, reducing maintenance difficulty and costs. In the prior art, the enclosure 12 is a single unit without the notch 13. This application effectively utilizes a portion of the enclosure 12 at the notch 13 as the bracket 2, making reasonable use of the housing structure without introducing additional structures.

[0036] Furthermore, the projected area of ​​the housing 1 on the ceiling is polygonal, and the notch 13 is formed at the corner of the housing 1. By placing the notch 13 at the corner of the housing 1, the water pump assembly is prevented from protruding too much on the ceiling machine, thereby reducing the space occupied by the ceiling machine and improving the overall integrity and aesthetics of the ceiling machine.

[0037] The water pump assembly includes at least one of the water pump 3 and the float switch 4. In the present application, the water pump assembly includes the water pump 3 and the float switch 4, facilitating the maintenance of the water pump 3 and the float switch 4 by disassembling the bracket 2. The float switch 4 is used to monitor the water level, and when the water level exceeds a certain height, the water pump 3 is used to drain in time. The bracket 2 includes a first support table 21, a second support table 22 and a baffle 23. The baffle 23 blocks the gap 13, and the first support table 21 and the second support table 22 are arranged on the inner side of the gap 13. That is, the first support table 21 and the second support table 22 are located in the space surrounded by the baffle 23 and the shell 1, preventing the first support table 21 and the second support table 22 from being directly exposed to the outside of the shell 1 and avoiding the collision of the first support table 21 and the second support table 22 with external objects. The water pump 3 is arranged on the first support table 21, and the float switch 4 is arranged on the second support table 22. The installation of the water pump 3 by using the first support table 21 and the installation of the float switch 4 by using the second support table 22 can make the layout of the water pump assembly more clear and reasonable, avoid the interference between the water pump 3 and the float switch 4, and facilitate the maintenance personnel to better distinguish and observe each component of the water pump assembly. In addition, the first support table 21 can bear the gravity of the water pump 3, and the second support table 22 can bear the gravity of the float switch 4, thereby optimizing the stress point distribution of the water pump 3 and the float switch 4 during assembly, which is conducive to improving the stress distribution during related assembly. Since the first support table 21 and the second support table 22 are located in the space surrounded by the baffle 23 and the shell 1, the water pump assembly can be protected by using the bracket 2 and the shell 1, preventing the collision between other components and the water pump assembly.

[0038] Further, the baffle 23 is provided with a drain pipe water nozzle 25. The water pump 3 includes a water inlet, a drain outlet and a drain pipe 5. One end of the drain pipe 5 is in communication with the drain outlet, and the other end is in communication with the drain pipe water nozzle 25. When the water pump 3 is working, the condensed water extracted by the water pump 3 enters the water inlet and is drained to the outside of the shell 1 through the drain pipe 5 and the drain pipe water nozzle 25.

[0039] Further, the baffle 23 is provided with a wire passing hole 24. The wire harness of the ceiling machine passes through the wire passing hole 24 and extends to the outside of the baffle 23. The disordered wire harness can be regularized, the layout of the wire is facilitated, the mutual entanglement between the wire harnesses is prevented, and the wire harness extends to the outside of the baffle 23, facilitating the plugging of the wire harness outside the shell 1 and reducing the operation difficulty. The wire passing hole 24 and the drain pipe water nozzle 25 are arranged on the upper side and the lower side of the baffle 23 respectively, preventing the two from being too close to affect the strength of the bracket 2. Arranging the drain pipe water nozzle 25 and the wire passing hole 24 on the bracket 2 can make full use of the space of the bracket 2 without changing the shell structure.

[0040] Further, the bracket 2 further comprises a reinforcing rib 26 for improving the overall strength of the bracket 2. The reinforcing rib 26 is arranged between the first support platform 21 and the second support platform 22, and / or arranged between the first support platform 21 and the baffle plate 23, and / or arranged between the second support platform 22 and the baffle plate 23. In the present application, the reinforcing rib 26 is arranged between the first support platform 21 and the baffle plate 23, one end of the reinforcing rib 26 is connected with the baffle plate 23, and the other end is connected with the first support platform 21. The strength of the bracket 2 is improved, which helps to stably support the water pump 3 by the first support platform 21 and stably support the float switch 4 by the second support platform 22, and improves the service life of the shell structure. Figures 6-7

[0041] Further, the side of the baffle plate 23 close to the valve plate 6 is bent to form a flange 27 towards the inner side of the shell 1, and the water pump assembly is located inside the accommodation space formed by the baffle plate 23 and the flange 27. The flange 27 not only limits the position of the water pump assembly to prevent the water pump assembly from deviating, but also saves space by the bending design, so that the structure of the water pump assembly is more compact and the occupied space of the ceiling machine is reduced.

[0042] Further, as shown in Figures 6-9 the shell 1 comprises a valve plate 6, one side of the valve plate 6 is detachably connected with the shell 1, the other side is detachably connected with the baffle plate 23, and a pipeline through hole is arranged between the valve plate 6 and the baffle plate 23. The detachable connection facilitates the disassembly and assembly of the valve plate 6 and the baffle plate 23. The valve plate 6 is provided with a first opening, the baffle plate 23 is provided with a second opening, and when the valve plate 6 and the baffle plate 23 are connected together, the first opening and the second opening cooperate to form the pipeline through hole. By the opening mode of the valve plate 6 and the baffle plate 23, not only the raw materials can be saved and the load of the bracket 2 is reduced, but also the pipeline and / or wire harness of the ceiling machine can pass through the pipeline through hole formed by the bracket 2 itself, which is convenient for the layout of the pipeline or wiring, and the pipeline and wire harness of the ceiling machine are regularized, and the structural compactness of the ceiling machine is improved. In the present application, the number of pipeline through holes is not specifically limited, which can be arranged according to the layout of the wire harness or pipeline of the ceiling machine. Preferably, the valve plate 6 and the baffle plate 23 are detachably connected, so that when the bracket 2 is disassembled, the water pump assembly can be maintained or repaired by disassembling only the baffle plate 23. Moreover, since the valve plate 6 and the baffle plate 23 are a split structure, they can be separated from each other during disassembly, and will not be disturbed by the pipeline and wire harness. The side of the flange 27 away from the baffle plate 23 extends to form a bent plate 28 away from the accommodation space, and the bent plate 28 is detachably connected with the valve plate 6. The bent plate 28 is the contact surface when the valve plate 6 and the baffle plate 23 are connected, and the contact surface of the valve plate 6 and the baffle plate 23 is increased by the bent plate 28, which not only facilitates the connection and installation, but also helps to improve the connection stability.

[0043] ​The valve plate 6 is detachably connected with the bottom plate 11 and the surrounding plate 12. Similarly, the baffle plate 23 is detachably connected with the bottom plate 11 and the surrounding plate 12. That is, the bracket 2 is connected with the surrounding plate 12 and the bottom plate 11, and the connection points of the bracket 2 and the shell 1 are increased through multiple connections, thereby improving the installation stability. The detachable connection between the bracket 2 and the shell 1 can be achieved through clamping, screwing or the like. Specifically, in the present application Figures 1-3 , the bracket 2 is provided with a first connecting hole, and the shell 1 is correspondingly provided with a second connecting hole. The connecting piece passes through the first connecting hole and the second connecting hole respectively, so as to realize the installation of the bracket 2 and the shell 1.

[0044] The shell structure of the present application is provided with a notch 13 at the surrounding plate 12, and the bracket 2 is detachably arranged at the notch 13 and blocks the notch 13. From the appearance, the present application is the same as the ceiling machine in the prior art. On the inner side of the surrounding plate 12, the water pump assembly is installed by using the bracket 2. The maintenance personnel can only disassemble the bracket 2 to expose the water pump assembly to the outside view, thereby reducing the maintenance difficulty.

[0045] Embodiment 2

[0046] On the basis of embodiment 1, the present embodiment provides a ceiling machine. The ceiling machine comprises a shell structure, a heat exchanger 100, a fan 10, a water collecting tray and an electric control box. The heat exchanger 100, the water collecting tray and the fan 10 are arranged on the inner side of the shell 1. The heat exchanger 100 and the surrounding plate 12 define the air duct of the ceiling machine. The water collecting tray is arranged below the heat exchanger 100 and is used for collecting the condensed water generated by the heat exchanger 100, so as to avoid the condensed water being directly discharged into the room and affecting the user experience. The water inlet of the water pump 3 is communicated with the water collecting tray. The water pump 3 pumps out the condensed water in the water collecting tray, and then the condensed water flows through the water outlet, the drain pipe 5 and the drain pipe water nozzle 25 and is discharged.

[0047] The heat exchanger 100 comprises a head end, a tail end, a gas-liquid pipe inlet pipe and a gas-liquid pipe outlet pipe, the head end, the tail end and the shell 1 form a mounting space, the gas-liquid pipe inlet pipe, the gas-liquid pipe outlet pipe and the water pump assembly are arranged at the mounting space, and the mounting space is arranged at the notch 13. The refrigerant flows in the pipeline formed by the gas-liquid pipe inlet pipe and the gas-liquid pipe outlet pipe. The gas-liquid pipe inlet pipe and the gas-liquid pipe outlet pipe are arranged in the mounting space, the gas-liquid pipe inlet pipe, the gas-liquid pipe outlet pipe and the water pump assembly are arranged at the same corner, that is, the gas-liquid pipe inlet pipe and the gas-liquid pipe outlet pipe are arranged close to the support 2. The mounting space can make the gas-liquid pipe inlet and outlet pipes and the water pump assembly arranged at the same corner. In this application, the gas-liquid pipe inlet and outlet pipes are arranged on the left side of the water pump assembly. Arranging the gas-liquid pipe inlet and outlet pipes on the left side of the water pump assembly can ensure that the length of the existing heat exchanger 100 is basically unchanged, and can accommodate the water pump assembly under the condition of ensuring that the notch 13 occupies a small space. If the gas-liquid pipe inlet and outlet pipes are arranged on the right side of the water pump assembly, the length of the heat exchanger 100 will be shortened. Further, the angle between the center of the water pump 3 and the connection between the gas-liquid pipe inlet and outlet pipes away from the water pump 3 and the horizontal line is defined as α, 45≤α<90. Through this setting, under the premise of saving space and making the shell structure more compact, the water pump assembly and the head and tail ends of the heat exchanger are prevented from being too close to each other and colliding. Further, α=52°.

[0048] The pipeline through hole is arranged at least two. Specifically, the valve plate 6 is provided with a first upper opening 61 and a first lower opening 62, and the baffle 23 is correspondingly provided with a second upper opening 71 and a second lower opening 72. When the valve plate 6 and the baffle 23 are connected together, the first upper opening 61 and the second upper opening 71 form an upper pipeline through hole 8, and the first lower opening 62 and the second lower opening 72 form a lower pipeline through hole 9. The gas-liquid pipe inlet pipe cooperates with the upper pipeline through hole 8, the gas-liquid pipe inlet pipe extends out of the upper pipeline through hole 8, the gas-liquid pipe outlet pipe cooperates with the lower pipeline through hole 9, and the gas-liquid pipe outlet pipe extends out of the lower pipeline through hole 9. Alternatively, the gas-liquid pipe outlet pipe cooperates with the upper pipeline through hole 8, the gas-liquid pipe outlet pipe extends out of the upper pipeline through hole 8, the gas-liquid pipe inlet pipe cooperates with the lower pipeline through hole 9, and the gas-liquid pipe inlet pipe extends out of the lower pipeline through hole 9. Arranging the gas-liquid pipe inlet and outlet pipes close to the support 2 provides installation positions for the gas-liquid pipe inlet and outlet pipes by using the upper pipeline through hole 8 and the lower pipeline through hole 9, and limits the gas-liquid pipe inlet and outlet pipes to prevent shaking, which can also prevent the pipelines from colliding with each other and ensure the refrigeration and heating effect of the heat exchanger. Using the structure of the support 2 itself provides installation positions for the gas-liquid pipe inlet and outlet pipes, which avoids setting other structures on the ceiling machine to install or position the gas-liquid pipe inlet and outlet pipes, is conducive to saving raw materials, and makes the structure of the ceiling machine more compact.

[0049] Further, as shown in FIG. 6, Figure 10As shown, the heat exchanger 100 comprises a plurality of straight heat exchange channels, two adjacent straight heat exchange channels are connected by an arc-shaped channel, the first end of the heat exchanger 100 is a first end portion 1011, the second end of the heat exchanger 100 is a second end portion 1041, the distance from the second end portion 1041 to the outer side of the first end portion 1011 is L5, the distance from the first end portion 1011 to the outer side of the second end portion 1041 is L6, wherein L5 / L6≤1.

By connecting adjacent straight heat exchange channels with arc-shaped channels and the proportional relationship between the sizes of the first end portion and the second end portion, the length of the existing heat exchanger 100 can be basically unchanged, that is, the heat exchange capacity of the heat exchanger 100 is unchanged, so that the first end and the second end of the heat exchanger 100 can accommodate the water pump assembly and the gas-liquid pipe inlet and outlet pipe. When the water pump assembly is installed and maintained, it brings great convenience to the workers. In addition, installing the water pump assembly at the break between the first end and the second end of the heat exchanger 100 will not damage the uniformity of the airflow in the air outlet duct, the heat quantity of the air blown from the ceiling machine is more uniform, the temperature of the air blown from different areas of the ceiling machine is the same, and the user's comfort is reduced.

[0050] Further, the heat exchanger 100 comprises a first heat exchange channel 101, a second heat exchange channel 102, a third heat exchange channel 103, and a fourth heat exchange channel 104 connected in sequence, the first heat exchange channel 100 and the second heat exchange channel 102 are connected by a first arc-shaped channel, the second heat exchange channel 102 and the third heat exchange channel 103 are connected by a second arc-shaped channel, and the third heat exchange channel 103 and the fourth heat exchange channel 104 are connected by a third arc-shaped channel. This setting can optimize the structure of the heat exchanger 100, not only increase the size of the end portion of the heat exchanger 100, but also improve the uniformity of the air outlet on the side of the heat exchanger 100 and improve the heat exchange efficiency of the heat exchanger 100.

[0052] Further, the first end portion 1011 and the second end portion 1041 are connected by a heat exchanger connecting plate 200. This setting can improve the connection firmness of the heat exchanger 100, so that the heat exchanger 100 is more stable.

[0053] Further, the length of the first heat exchange channel 101 is L1, the length of the second heat exchange channel 102 is L2, the length of the third heat exchange channel 103 is L3, and the length of the fourth heat exchange channel 104 is L4, wherein L1

[0054] Further, the inner radius of the first arc-shaped channel A is R1, the inner radius of the second arc-shaped channel B is R2, and the inner radius of the third arc-shaped channel C is R3, wherein R1=R2≤R3. Preferably, R1=R2=R3=90-100 mm, and more preferably, R1=R2=R3=94 mm. This arrangement can increase the space at the end of the heat exchanger 100, facilitating the placement of the water pump assembly in the space, and facilitating the installation and maintenance of the water pump assembly.
