Figure 1 As shown, it includes an evaporator and a surrounding plate. The evaporator is provided with a straight section structure, and a water pump is installed between the straight section structure and the surrounding plate. However, due to the straight section structure of the evaporator, the outer space of the straight section is narrow, which brings great inconvenience to the staff during the installation and maintenance of the water pump. In addition, installing the water pump on the straight section side will destroy the uniformity of the air flow in the air outlet duct, and the heat of the air blown out from the ceiling hood is uneven, so that the temperature of the air blown out from different areas of the ceiling hood is different, which reduces the comfort of users. Summary of the invention

[0003] In view of this, the present invention aims to propose a ceiling hood to solve the problem that in the prior art, the evaporator is provided with a straight section structure, and a water pump is installed between the straight section structure and the enclosure, but due to the straight section structure of the evaporator, the outer space of the straight section is narrow, which brings great inconvenience to the staff during the installation and maintenance of the water pump; in addition, installing the water pump on the straight section side will destroy the uniformity of the air flow in the air outlet duct, and the heat of the air blown out from the ceiling hood is uneven, so that the air temperature blown out from different areas of the ceiling hood is different, which reduces the comfort of users.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A ceiling machine includes an evaporator, the evaporator includes a plurality of straight heat exchange channels, two adjacent straight heat exchange channels are connected by an arc channel, the two ends of the evaporator include a first end and a second end, the distance from the second end to the outer side of the first end is L5, and the distance from the first end to the outer side of the second end is L6, wherein L5 / L6≤1.

[0006] In this arrangement, adjacent straight heat exchange channels are connected by arc-shaped channels, and the proportional relationship between the sizes of the first end and the second end can ensure that the length of the existing evaporator remains basically unchanged, that is, the heat exchange capacity of the evaporator remains unchanged, so that the end of the evaporator can accommodate a water pump and inlet and outlet pipes, which brings great convenience to the staff during the installation and maintenance of the water pump; in addition, installing a water pump at the end of the evaporator will not destroy the uniformity of the airflow in the air outlet duct, and the heat of the wind blown out from the ceiling hood is more uniform, so that the temperature of the wind blown out from different areas of the ceiling hood is the same, thereby improving the user's comfort.

[0007] Further, a distance L5 from the second end to the outer side of the first end is 170 mm to 190 mm, and a distance L6 from the first end to the outer side of the second end is 200 mm to 230 mm.

[0008] This arrangement makes it easy to install the water pump between the first end and the second end, and is convenient for workers to install and overhaul.

[0009] Furthermore, the multiple straight heat exchange channels include a first heat exchange channel, a second heat exchange channel, a third heat exchange channel, and a fourth heat exchange channel connected in sequence, the first heat exchange channel is connected to the second heat exchange channel through a first curved channel, the second heat exchange channel is connected to the third heat exchange channel through a second curved channel, and the third heat exchange channel is connected to the fourth heat exchange channel through a third curved channel.

[0010] This arrangement can increase the space between the first end and the second end.

[0011] Further, the inner radius of the first arc-shaped channel is R1, the inner radius of the second arc-shaped channel is R2, and the inner radius of the third arc-shaped channel is R3, wherein R1=R2≤R3.

[0012] This arrangement can increase the distance between the first end and the second end of the evaporator, so that the water pump can be arranged between the first end and the second end, avoiding the influence of the water pump on the uniformity of the air outlet temperature of the ceiling machine, and improving the user's comfort.

[0013] Further, the first end is arranged at an end of the first heat exchange channel away from the second heat exchange channel, and the second end is arranged at an end of the fourth heat exchange channel away from the third heat exchange channel.

[0016] Furthermore, the inner radius R1 of the first arc-shaped channel, the inner radius R2 of the second arc-shaped channel, and the inner radius R3 of the third arc-shaped channel are 90 mm to 100 mm.

[0017] This arrangement facilitates increasing the space between the ends of the evaporator, facilitates installing a water pump at the end of the evaporator, and also facilitates repairing the water pump. Moreover, installing the water pump at the end of the evaporator will not affect the air outlet efficiency.

[0018] Furthermore, the first end portion and the second end portion are connected via an evaporator connecting plate.

[0019] This setting prevents wind from coming out of the end of the evaporator and reducing the efficiency of the ceiling unit.

[0020] Furthermore, it also includes an electric heating device, a wire pressing device, and a chassis, wherein the chassis is provided with bottom plate foam, and the electric heating device and the wire pressing device are both arranged on the chassis through the bottom plate foam, and the electric heating device and the wire pressing device are staggered along the circumference on the inner side of the evaporator.

[0021] This arrangement can effectively avoid overlap and mutual interference between the wire pressing device and the electric heating device through the staggered arrangement of the electric heating device and the wire pressing device, and affect the disassembly and assembly efficiency of the ceiling machine. In addition, the auxiliary role of the chassis foam can also improve the safety of the operation of the internal devices of the ceiling machine, and is also beneficial to the isolation effect between devices, effectively avoiding mutual interference between the components of the internal devices of the ceiling machine, improving the independence of the device, saving space in the internal cavity of the ceiling machine, and enhancing the heat exchange efficiency.

[0022] Furthermore, it also includes a water pump assembly, which is arranged on the chassis and close to the first end. This arrangement can effectively avoid the influence of the water pump assembly on the uniformity of the air outlet duct outside the evaporator, and also facilitates the installation and maintenance of the water pump assembly.

In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0044] Example 1

[0045] like Figure 1 As shown, the present invention provides a ceiling machine, which includes an evaporator 100, a water pump assembly, a chassis, and a fan 500. The chassis includes a bottom plate 600 and a surrounding plate 700 arranged on the periphery of the bottom plate 600; the evaporator 100, the water pump assembly, and the fan 500 are all arranged on the inner side of the surrounding plate 700, and the water pump assembly is arranged at the end of the evaporator, and the two ends of the evaporator are connected by an evaporator connecting plate 200.

[0046] The evaporator 100 includes a plurality of straight heat exchange channels, and two adjacent straight heat exchange channels are connected by an arc channel. The two ends of the evaporator include a first end 1011 and a second end 1041. The distance from the second end 1041 to the outer side of the first end 1011 is L5, and the distance from the first end 1011 to the outer side of the second end 1041 is L6, wherein L5 / L6≤1. Preferably, 0.6≤L5 / L6≤1, preferably, L5=170-190mm, L6=200-230mm, more preferably, L5=179mm, L6=215mm, and L5 / L6≈0.83.

[0047] The present invention connects adjacent straight heat exchange channels with arc-shaped channels, and the proportional relationship between the sizes of the first end and the second end can ensure that the length of the existing evaporator remains basically unchanged, that is, the heat exchange capacity of the evaporator remains unchanged, so that the end of the evaporator can accommodate a water pump and inlet and outlet pipes, which brings great convenience to the staff during the installation and maintenance of the water pump; in addition, installing a water pump at the end of the evaporator will not destroy the uniformity of the airflow in the air outlet duct, and the heat of the wind blown out from the ceiling hood is more uniform, so that the temperature of the wind blown out from different areas of the ceiling hood is the same, thereby reducing the comfort of users.

[0048] Specifically, the water pump assembly is arranged on the chassis and close to the first end 1011. This arrangement facilitates the installation and maintenance of the water pump assembly; in addition, a valve plate assembly is also arranged close to the first end 1011, and the valve plate assembly is used to fix the pipeline inlet and outlet pipes.

[0049] Specifically, the evaporator includes 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, which are connected in sequence. The first heat exchange channel 100 is connected to the second heat exchange channel 102 through a first arc channel, the second heat exchange channel 102 is connected to the third heat exchange channel 103 through a second arc channel, and the third heat exchange channel 103 is connected to the fourth heat exchange channel 104 through a third arc channel. This setting can not only increase the size of the end of the evaporator by optimizing the structure of the evaporator, but also improve the uniformity of the air outlet around the evaporator and improve the heat exchange efficiency of the evaporator.

[0050] Specifically, the first end 1011 is disposed at an end of the first heat exchange channel 101 away from the second heat exchange channel 102 , and the second end 1041 is disposed at an end of the fourth heat exchange channel 104 away from the third heat exchange channel 103 .

[0051] Specifically, the first end 1011 and the second end 1041 are connected via the evaporator connecting plate 200. This arrangement can improve the connection firmness of the evaporator and make the evaporator more stable.

[0052] Specifically, 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<L4<L3<L2. Preferably, L1=310mm-350mm, L2=420-450mm, L4=360-380mm, L3=410-440mm, more preferably, L1=333mm, L2=435mm, L4=374mm, L3=430mm.

[0053] Specifically, 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 evaporator, making it easier to place the water pump in the space and facilitate the installation and maintenance of the water pump.

[0054] In addition, in the prior art, for air conditioners equipped with electric heating, in order to ensure the safe operation of the electric heating, a sensor for collecting the electric heating temperature is usually installed on the electric heating, and a controller is used to control the operation of the electric heating according to the collected temperature to prevent accidents from happening to the electric heating, causing hazards such as fire; however, the existing electric heating is equipped with a sensor in a complex manner, which has low safety, and the electric heating is placed in the straight section of the evaporator. Figure 1 As shown, it takes up a lot of space.

[0055] In order to solve the problems in the prior art that the internal layout of the ceiling machine is relatively complicated, especially the setting positions of the electric heating device and the wire pressing device in the ceiling machine occupy a large space, and the disassembly and assembly efficiency of the ceiling machine is low; the present invention provides another embodiment, the ceiling machine also includes an electric heating device 300 and a wire pressing device 400, and the electric heating device 300 and the wire pressing device 400 are arranged in the gap between the fan and the evaporator, and the bottom plate 600 is provided with a bottom plate foam 601, and the bottom plate foam 601 is provided with a plurality of first avoidance gaps 6011 and second avoidance gaps 6012, and the electric heating device 300 and the wire pressing device 400 are both arranged on the bottom plate 600 through the corresponding first avoidance gaps 6011 and second avoidance gaps 6012 of the bottom plate foam 601, and are located on the inner side of the enclosure, preferably, the electric heating device 300 and the wire pressing device 400 are staggered along the circumference in the gap between the evaporator and the fan. Through the layout inside the ceiling machine, the setting positions of the electric heating device 300 and the wire crimping device 400 can be optimized, the component layout inside the ceiling machine can be improved, the space occupied by the electric heating device 300 and the wire crimping device 400 inside the ceiling machine can be saved, the heat exchange efficiency inside the ceiling machine can be increased, the disassembly and assembly efficiency of the ceiling machine can be improved, and the maintenance cost of the ceiling machine can be reduced. The setting of the bottom plate foam 600 is beneficial to improving the stability and safety of the installation of the electric heating device 300 and the wire crimping device, and can also effectively protect other devices and enhance the thermal insulation effect, thereby improving the heat exchange efficiency of the evaporator.

[0056] Specifically, at least one electric heating device 300 and a wire pressing device 400 are provided, and the number of the first avoidance gap and the second avoidance gap corresponds to the number of the corresponding electric heating devices and wire pressing devices. The setting position of the electric heating device 300 corresponds to the position of the arc channel of the evaporator, and the electric heating device 300 is provided inside the arc channel. The projection shape of the electric heating device 300 is square or arc-shaped; the projection shape of the electric heating device 400 is square, such as Figure 2-3As shown, the electric heating device 300 is arranged on the inner side of the arc-shaped channel, and the angle between the plane where the long side of the electric heating device 300 is located and the straight heat exchange channel of the evaporator 100 is an acute angle α, and the value range of α is (0°, 90°). Preferably, α=45°. The projection shape of the electric heating device 300 is an arc. The electric heating device 300 and the arc-segment channel are arranged in a shape, and there is a certain gap between the electric heating device 300 and the arc-shaped channel. The arrangement of the electric heating device 300 is conducive to saving space inside the ceiling machine and increasing the heat exchange efficiency of the evaporator 100. In addition, the electric heating The device 300 includes an electric heater 301 and a support column 302. The electric heater 301 is connected to the support column 302 by screws. The support column 302 is set on the bottom plate through the first avoidance gap 6011 of the bottom plate foam 601. The opening shape of the first avoidance gap is consistent with the bottom shape of the electric heating device 300, which is convenient for the support column of the electric heating device to pass through one end close to the enclosure. The electric heater 301 includes an electric heating plate and a heating bracket. At least two heating brackets are provided. Electric heating plates are arranged on the inner sides of the two heating brackets. The two heating brackets are respectively connected to the support column by screws. The wire crimping device 400 is arranged on the inner side of the straight heat exchange channel, and the setting position of the wire crimping device 400 corresponds to any one setting position of the second heat exchange channel 102, the third heat exchange channel 103, and the fourth heat exchange channel 104, or the setting position of the wire crimping device 6 corresponds to any multiple setting positions of the second heat exchange channel 102, the third heat exchange channel 103, and the fourth heat exchange channel 104, respectively. The wire crimping device 400 is a wire crimping buckle, which is used to summarize and comb the connecting wires of the internal components of the ceiling machine. The wire crimping device 400 is arranged on the bottom plate through a second avoidance gap, and the opening shape of the second avoidance gap is consistent with the bottom shape of the wire crimping device, so that the wire crimping device can pass through one end close to the enclosure.

[0057] Preferably, three electric heating devices 300 and wire pressing devices 400 are provided, and the electric heating devices 300 are respectively provided on the inner sides of the positions where the three arc-shaped channels are located, and the wire pressing devices 400 are respectively provided on the inner sides of the second heat exchange channel 102, the third heat exchange channel 103, the fourth heat exchange channel 104, and relative positions, that is, the wire pressing devices 400 are respectively provided on the inner sides of the positions where the second heat exchange channel 102, the third heat exchange channel 103, and the third heat exchange channel 104 are located, and the three wire pressing devices 400 and the three electric heating devices 300 are staggered along the circumference on the outer side of the fan 500, and the fan 500 is provided on the bottom plate through the third avoidance gap, and the opening shape of the third avoidance gap is consistent with the bottom shape of the fan, so as to facilitate the installation of the fan near one end of the enclosure, and the bottom plate foam part also includes a fourth avoidance gap, and the opening shape of the fourth avoidance gap is consistent with the bottom shape of the fixed bracket, so as to facilitate the installation of the fixed bracket near one end of the enclosure.

[0058] Through the special setting of the electric heating device, which is different from the prior art in which the electric heating device is set on the inner side of the straight section 9 of the evaporator, it not only occupies a large amount of space inside the ceiling machine, but also easily limits the setting position of the wire buckle, thereby causing the layout stability of the internal components of the ceiling machine to be poor, and failing to effectively achieve the stability and reliability of the operation of the ceiling machine. The electric heating device in this application adopts a detachable configuration of the electric heater 301 and the support column 302, which can improve the installation efficiency of the electric heating device 300 during the installation process, and can reduce the opening size of the first avoidance gap on the bottom plate foam 601, thereby enhancing the strength of the bottom plate foam 601, and avoiding the problem of low structural strength of the bottom plate foam 601 due to too many avoidance gap openings, which can effectively enhance the protective effect of the components on the inner side of the bottom plate foam 600 evaporator and improve the stability and safety of the internal components of the ceiling machine.

[0059] Example 2

[0060] On the basis of Example 1, Figure 4-Figure 12 As shown, the ceiling machine of this embodiment also includes a bracket 1, and the water pump assembly is arranged on the bracket 1. The water pump assembly, chassis and bracket are arranged on the ceiling machine to accommodate and protect the various components of the ceiling machine, avoid collision between other objects and components of the ceiling machine, and improve the reliability of the ceiling machine during transportation, installation and use. The ceiling machine will produce condensed water in the cooling mode, and the water pump assembly is used to discharge the condensed water in time to ensure the safety of the use of the ceiling machine and avoid affecting the normal operation of the ceiling machine. The bracket 1 is used to support and install the water pump assembly.

[0061] Specifically, the enclosure 700 has a first notch 701, and the bracket 1 is detachably arranged at the first notch 701 and blocks the first notch 701, so as to prevent the first notch 701 from affecting the air inlet and outlet of the ceiling machine, and at the same time, it is also beneficial to the integrity and aesthetics of the water pump assembly, the chassis and the bracket. Since the water pump assembly is arranged on the bracket 1, and the bracket 1 is detachable, the water pump assembly can be exposed to the external field of vision only by disassembling the bracket 1, and is not blocked by other components of the ceiling machine, so that the maintenance personnel can observe the condition of the water pump assembly more intuitively. At the same time, the enclosure 700 is provided with the first notch 701, and the water pump assembly is installed at the first notch 701, so there is no need to set an inspection port on the water pump assembly, the chassis and the bracket. The maintenance personnel do not need to extend their hands or maintenance tools into the narrow inspection port, so that the maintenance personnel have a larger operating space. The maintenance personnel only need to disassemble the bracket 1 to realize the disassembly of the water pump assembly, which is convenient for the maintenance personnel to disassemble and maintain the water pump assembly on the outside of the ceiling machine, reducing the difficulty and cost of maintenance. In the prior art, the enclosure 700 is a whole without the first notch 701. The present application is equivalent to utilizing part of the enclosure 700 at the first notch 701 as the bracket 1, which can reasonably utilize the water pump assembly, chassis and bracket without introducing other unnecessary structures.

[0062] Specifically, the projection area of ​​the chassis on the ceiling is a polygon, the first notch 701 is formed at the corner of the chassis, and the first notch 701 is located in the accommodation space formed by the first end 1011 and the second end 1041, and the first notch 701 is close to the first end 1011. The present invention increases the accommodation space of the first end and the second end, and sets the water pump assembly in the space, and sets the first notch close to the first end, which not only avoids the water pump assembly from being too protruding on the ceiling machine, thereby reducing the occupied space of the ceiling machine, but also helps to improve the integrity and aesthetics of the ceiling machine. When installing and repairing the water pump, it brings great convenience to the staff, and will not destroy the uniformity of the air flow in the air outlet duct. The heat of the wind blown out from the ceiling machine is more uniform, so that the temperature of the wind blown out from different areas of the ceiling machine is the same, which improves the comfort of users. The water pump assembly includes at least one of a water pump 2 and a float switch 3. In the present application, the water pump assembly includes a water pump 2 and a float switch 3, which is convenient for repairing the water pump 2 and the float switch 3 by disassembling the bracket 1. The float switch 3 is used to monitor the water level. When the water level exceeds a certain height, it is discharged in time through the water pump 2. The bracket 1 includes a first support platform 11, a second support platform 12 and a baffle 13. The baffle 13 blocks the first notch 701. The first support platform 11 and the second support platform 12 are arranged on the inner side of the first notch 701. That is, the first support platform 11 and the second support platform 12 are located in the space surrounded by the baffle 13 and the chassis, so as to prevent the first support platform 11 and the second support platform 12 from being directly exposed to the outside of the chassis and avoid the first support platform 11 and the second support platform 12 from being hit by foreign objects. The water pump 2 is arranged on the first support platform 11, and the float switch 3 is arranged on the second support platform 12. The water pump 2 is installed by the first support platform 11, and the float switch 3 is installed by the second support platform 12, so that the layout of the water pump assembly can be clearer and more reasonable, and the water pump 2 and the float switch 3 can be prevented from interfering with each other, and it is also convenient for maintenance personnel to better distinguish and observe the various components of the water pump assembly. The first support platform 11 can bear the gravity of the water pump 2, and the second support platform 12 can bear the gravity of the float switch 3, which optimizes the distribution of force points of the water pump 2 and the float switch 3 during assembly, which is conducive to improving the force distribution during relevant assembly. Since the first support platform 11 and the second support platform 12 are located in the space surrounded by the baffle 13 and the chassis, the bracket 1 and the chassis can be used to protect the water pump assembly to prevent other components from colliding with the water pump assembly.

[0063] Specifically, the baffle 13 is provided with a drain pipe water nozzle 15. The water pump 2 includes a water inlet, a drain outlet and a drain pipe 4, one end of the drain pipe 4 is connected to the drain outlet, and the other end is connected to the drain pipe water nozzle 15. When the water pump 2 is working, the condensed water pumped out by the water pump 2 enters from the water inlet, and is drained to the outside of the chassis through the drain pipe 4 and the drain pipe water nozzle 15 and discharged.

[0064] Specifically, the baffle 13 is provided with a wire hole 14, and the wire harness of the ceiling machine passes through the wire hole 14 and extends out of the baffle 13, which can organize the messy wire harness, facilitate the layout of the lines, and prevent the wire harnesses from being entangled with each other. The wire harness extends out of the baffle 13, which is convenient for plugging and unplugging the wire harness outside the chassis, reducing the difficulty of operation. The wire hole 14 and the drain pipe nozzle 15 are respectively arranged on the upper and lower sides of the baffle 13 to prevent the distance between the two from being too close to affect the strength of the bracket 1. By arranging the drain pipe nozzle 15 and the wire hole 14 on the bracket 1, the space of the bracket 1 can be fully utilized without changing the water pump assembly, the chassis and the bracket.

[0065] Specifically, the bracket 1 further includes a reinforcing rib 16 for improving the overall strength of the bracket 1. The reinforcing rib 16 is provided between the first support platform 11 and the second support platform 12, and / or between the first support platform 11 and the baffle 13, and / or between the second support platform 12 and the baffle 13. Figure 9-10 In the embodiment, a reinforcing rib 16 is provided between the first supporting platform 11 and the baffle 13, one end of the reinforcing rib 16 is connected to the baffle 13, and the other end is connected to the first supporting platform 11. The improved strength of the bracket 1 helps the first supporting platform 11 to stably support the water pump 2, and the second supporting platform 12 to stably support the float switch 3, thereby increasing the service life of the water pump assembly, the chassis and the bracket.

[0066] Specifically, one side of the baffle 13 is bent toward the inner side of the chassis to form a flange 17, and the water pump assembly is located inside the accommodation space formed by the baffle 13 and the flange 17. The flange 17 can not only limit the water pump assembly to prevent the water pump assembly from being offset, making the structure of the water pump assembly more compact and reducing the space occupied by the ceiling machine, but also the outer side of the flange 17 is the inlet and outlet pipe position of the refrigerant pipeline, which is equivalent to forming an accommodation space for the pipeline to prevent the pipeline joint from exceeding the entire periphery of the enclosure, so that it is easy to pack in production.

[0067] Specifically, Figure 9-12As shown, the bracket 1 includes a first side panel 5 and a second side panel 6, and the first side panel 5 and the second side panel 6 are connected together to form the bracket 1. The first side panel 5 and the second side panel 6 are detachably connected to facilitate the decomposition or assembly of the bracket 1, or the first side panel 5 and the second side panel 6 are integrally formed to improve the strength of the bracket 1. Preferably, the first side panel 5 and the second side panel 6 are detachably connected. The first support platform 11, the second support platform 12 and the baffle 13 are all arranged on the second side panel 6. The first side panel 5 is provided with a first opening, and the second side panel 6 is provided with a second opening. When the first side panel 5 and the second side panel 6 are connected together, the first opening and the second opening cooperate to form a mounting hole. By opening holes in the first side panel 5 and the second side panel 6, not only can raw materials be saved and the load-bearing capacity of the bracket 1 be reduced, but also the mounting holes formed by the bracket 1 itself can be used to allow the pipes and / or wiring harnesses of the ceiling machine to pass through, which is convenient for the layout or routing of the pipes, the pipes and wiring harnesses of the ceiling machine are regularized, and the compactness of the structure of the ceiling machine is improved. In the present application, there is no specific limitation on the number of mounting holes, and they can be set according to the layout of the ceiling wiring harness or pipeline. Preferably, the first side panel 5 and the second side panel 6 are detachably connected, so that when the bracket 1 is disassembled, the water pump assembly can be maintained or repaired by only disassembling the second side panel 6. Moreover, since the first side panel 5 and the second side panel 6 are split structures, they can be separated from each other during disassembly and assembly, and will not be interfered by pipelines and wiring harnesses. The flange 17 extends in the direction of the first side panel 5 to form a bending plate 18, and the bending plate 18 and the first side panel 5 are detachably connected. The bending plate 18 is the contact surface when the first side panel 5 and the second side panel 6 are connected. The bending plate 18 increases the contact surface of the first side panel 5 and the second side panel 6, which not only facilitates the connection and installation, but also helps to improve the connection stability.

[0068] The first side panel 5 is detachably connected to the chassis, and the second side panel 6 is detachably connected to the chassis, so as to realize the installation of the bracket 1 and the chassis. The first side panel 5 is not only detachably connected to the bottom plate, but also detachably connected to the enclosure. Similarly, the second side panel 6 is not only detachably connected to the bottom plate, but also detachably connected to the enclosure. That is, the bracket 1 is not only connected to the enclosure, but also to the bottom plate. By connecting multiple locations, the connection points between the bracket 1 and the chassis are increased, thereby improving the installation stability. The detachable connection between the bracket 1 and the chassis can be achieved by means of snap connection, screw connection, etc. Specific to the present application Figure 4-6 In the embodiment, the bracket 1 is provided with a first connection hole, and the chassis is correspondingly provided with a second connection hole, and the connecting member passes through the first connection hole and the second connection hole respectively to realize the installation of the bracket 1 and the chassis.

[0069] In the present application, a first notch 701 is provided at the enclosure 700, and a bracket 1 is detachably provided at the first notch and blocks the first notch 701. From the appearance, the ceiling machine of the present application is the same as the ceiling machine in the prior art. The water pump assembly is installed on the inner side of the enclosure using the bracket 1. The maintenance personnel can expose the water pump assembly to the outside view by only removing the bracket 1, thereby reducing the difficulty of maintenance.

[0070] The ceiling machine in the present application also includes a water receiving tray, which is arranged on the inner side of the chassis. The evaporator and the enclosure define the air duct of the ceiling machine. The water receiving tray is arranged below the evaporator to receive the condensed water generated by the evaporator, so as to prevent the condensed water from being directly discharged into the room and affecting the user experience. The water inlet of the water pump 2 is connected to the water receiving tray, and the water pump 2 draws out the condensed water in the water receiving tray, and then flows through the drain port, the drain pipe 4 and the drain pipe water nozzle 15 before being discharged.

[0071] The evaporator includes a gas-liquid pipe inlet and a gas-liquid pipe outlet, and the refrigerant flows in a pipeline formed by the gas-liquid pipe inlet and the gas-liquid pipe outlet. The gas-liquid pipe inlet and the gas-liquid pipe outlet are arranged at the first notch 701. That is, the gas-liquid pipe inlet and the gas-liquid pipe outlet are arranged close to the bracket 1. At least two mounting holes are arranged. Specifically, the first side plate 5 is provided with a first upper opening 51 and a first lower opening 52, and the second side plate 6 is correspondingly provided with a second upper opening 61 and a second lower opening 62. When the first side plate 5 and the second side plate 6 are connected together, the first upper opening 51 and the second upper opening 61 form an upper mounting hole 7, and the first lower opening 52 and the second lower opening 62 form a lower mounting hole 8. The gas-liquid pipe inlet cooperates with the upper mounting hole 7, and the gas-liquid pipe inlet extends out of the upper mounting hole 7, and the gas-liquid pipe outlet cooperates with the lower mounting hole 8, and the gas-liquid pipe outlet extends out of the lower mounting hole 8. Alternatively, the gas-liquid pipe outlet is matched with the upper mounting hole 7, and the gas-liquid pipe outlet extends out of the upper mounting hole 7, and the gas-liquid pipe inlet is matched with the lower mounting hole 8, and the gas-liquid pipe inlet extends out of the lower mounting hole 8. The gas-liquid pipe inlet and outlet are arranged close to the bracket 1, and the upper mounting hole 7 and the lower mounting hole 8 are used to provide an installation position for the gas-liquid pipe inlet and outlet, and the gas-liquid pipe inlet and outlet are limited to prevent shaking, and collision between pipes can be avoided to ensure the cooling and heating effect of the evaporator. The structure of the bracket 1 itself is used to provide an installation position for the gas-liquid pipe inlet and outlet, avoiding the need to set other structures on the ceiling machine to install or position the gas-liquid pipe inlet and outlet, which is beneficial to saving raw materials and making the structure of the ceiling machine more compact.
