Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a hoisting machine. Background Technology

[0002] The air conditioner is a core component of an air conditioning system. It draws in outside air through the air inlet using a built-in fan, pressurizes and accelerates it, and then exchanges heat through a heat exchanger. Finally, it delivers the regulated air to the target space through the air outlet to achieve the functions of cooling, heating or ventilation, and maintain the temperature, humidity and air quality of the target space.

[0003] In related technologies, floor-mounted air conditioners are generally installed horizontally. However, in some cases, vertical installation is necessary to ensure the comfort of the airflow. Condensation easily accumulates on the outer surface of the evaporator inside the floor-mounted air conditioner. Although a drip tray is installed, current designs only effectively collect condensation when the air conditioner is installed horizontally. When installed vertically, the drip tray can only collect condensation flowing down the evaporator surface to the bottom. Condensation on the refrigerant outlet pipe cannot flow downwards and may drip, leading to dripping and splashing of condensation on the refrigerant outlet pipe. This can cause corrosion and short circuits in the internal components of the floor-mounted air conditioner.

[0004] Therefore, how to solve the problem that the hoisting machine in the relevant technology cannot meet the two installation requirements of horizontal and vertical installation has become an important technical problem to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a hoisting machine to solve the defect of hoisting machines in related technologies that cannot meet the two installation requirements of horizontal and vertical installation.

[0006] This utility model provides a hoisting machine, comprising: shell; An evaporator is inclinedly disposed within the outer casing, the evaporator comprising an evaporator body and branch pipes and a main pipe for supplying refrigerant output; The main water receiving tray includes a first water receiving part and a second water receiving part. Along the vertical direction of the outer shell, the projection area of ​​the evaporator is located within the projection area of ​​the first water receiving part. Along the longitudinal direction of the outer shell, at least one end of the evaporator body is located within the projection area of ​​the second water receiving part. The longitudinal direction of the outer shell is perpendicular to the vertical direction of the outer shell. A secondary water receiving assembly is disposed on the side of the evaporator body near the second water receiving part. The secondary water receiving assembly includes a first water receiving tray and a second water receiving tray. The first water receiving tray is sleeved on the outside of the main pipeline. Along the longitudinal direction of the outer shell, the projection area of ​​the branch pipeline is located within the projection area of ​​the second water receiving tray.

[0007] This configuration allows the condensate draining from the evaporator surface to be collected when the evaporator is placed horizontally, thanks to the first water-receiving section of the main water tray. When the evaporator is placed vertically, the second water-receiving section of the main water tray and the auxiliary water tray assembly can also collect the condensate. This effectively collects condensate from the evaporator surface in both horizontal and vertical configurations, thus meeting the requirements for both horizontal and vertical installations and resolving the issue in related technologies where evaporator designs could not meet these two installation requirements.

[0008] According to the present invention, a hoisting machine is provided, wherein the first water receiving tray includes: The first tray is used to collect condensate, and the projection area of ​​the main pipeline is located within the projection area of ​​the first tray along the longitudinal direction of the outer shell. A sleeve is disposed inside the first disc body and penetrates the bottom wall of the first disc body. The sleeve is adapted for the main pipeline to pass through, and the inner wall of the sleeve is in sealing contact with the outer wall of the main pipeline.

[0009] With this configuration, the first water tray can effectively collect condensate from the outer surface of the main pipeline, which can effectively prevent corrosion and short circuits of the internal components of the hoist caused by condensate from the outer surface of the main pipeline.

[0010] According to the present invention, a hoisting machine is provided, wherein the first disc and the sleeve are both made of elastic material, and the sleeve and the first disc are formed with a slit, the slit penetrating the side wall of the sleeve, the bottom wall of the first disc and the side wall of the first disc along the axial direction of the sleeve. The first water receiving tray also includes: A binding element is provided around the outside of the sleeve, the binding element being adapted to fix the sleeve to the main pipeline and press the sleeve at the cut position.

[0011] This design allows for the application of force to both sides of the cut on the first drip tray when it is installed onto the main pipe. This causes elastic deformation near the cut, increasing the gap at the cut and aligning it with the main pipe. This allows the main pipe to pass through the cut and enter the sleeve of the first drip tray, thus fitting the first drip tray over the main pipe for easy installation. Furthermore, the binding components reduce the gap at the cut, ensuring the integrity of the bottom wall of the first drip tray and preventing condensate leakage.

[0012] According to the present invention, a lifting machine is provided in which a protrusion is formed on the bottom wall of the first disc body, the protrusion extends radially along the sleeve, one end of the protrusion extends to the outer side wall of the sleeve, the other end of the protrusion extends to the side wall of the first disc body, and the slit is located at the top of the protrusion.

[0013] This design increases the difficulty of condensate in the first drip tray overflowing outwards through the cut.

[0014] According to the present invention, a lifting machine is provided in which a guide portion is formed at the end of the sleeve away from the first disc body, the guide portion comprising: A flow guide cone surface is formed on the outer wall of the end of the sleeve away from the first disc body; Two flow guiding slopes are formed on the end face of the sleeve away from the first disc body, and both flow guiding slopes are inclined toward the central axis of the sleeve.

[0015] This design can reduce or prevent the accumulation of condensate at the cut end of the sleeve, and reduce the possibility of condensate leakage in the gap between the sleeve and the main pipeline and at the cut end.

[0016] According to the present invention, a hoisting machine is provided, wherein the outer shell has a bearing surface, and the bearing surface is perpendicular to the vertical direction of the outer shell; Along the vertical direction of the outer casing, the first water receiving part is located on the side of the evaporator body away from the bearing surface, and the second water receiving part is located on the side of the first water receiving part closer to the evaporator; Along the longitudinal direction of the outer casing, the first water receiving tray, the second water receiving tray, and the second water receiving part are all located on the side of the evaporator away from the air outlet of the outer casing. The second water receiving tray is located on the side of the first water receiving tray away from the evaporator, and the second water receiving part is located on the side of the second water receiving tray away from the first water receiving tray.

[0017] With this configuration, when the hoist is placed horizontally, the bearing surface is positioned horizontally above the evaporator, and the first water receiving part is positioned below the evaporator. When the hoist is placed vertically, the bearing surface is positioned vertically, and the second water receiving part, the first water receiving tray, and the second water receiving tray are all located below the evaporator. Furthermore, the height of the second water receiving tray is lower than the height of the first water receiving tray, and the height of the second water receiving part is lower than the height of the second water receiving tray.

[0018] According to the present invention, a dropper is provided with a drain hole on the bottom wall of the first water receiving tray, and the projection area of ​​the drain hole is located within the projection area of ​​the second water receiving tray along the longitudinal direction of the outer shell. The second water receiving tray is provided with a drainage groove at one end near the second water receiving part. Along the longitudinal direction of the outer shell, the projection area of ​​the drainage groove at least partially overlaps with the projection area of ​​the second water receiving part. The main water receiving tray is provided with a drain outlet, which is located on the bottom wall of the second water receiving part and at the edge of the second water receiving part near the first water receiving part. The drain outlet is adapted to connect to the drainage system of the hoist.

[0019] With this configuration, condensate collected in the first drip tray flows to the second drip tray through the drain hole, and condensate in the second drip tray flows to the second drip section through the drain channel. Condensate in the auxiliary drip tray is discharged outward through the main drip tray, eliminating the need for a separate drainage system for the auxiliary drip tray. This design is simple and space-saving. Whether the hoist is placed horizontally or vertically, condensate in the main drip tray can be discharged promptly, preventing condensate buildup.

[0020] According to the present invention, a lifting machine is provided, wherein the first water receiving tray has a drain pipe, one end of the drain pipe is connected to the drain hole, and the other end of the drain pipe extends toward the second water receiving tray.

[0021] With this design, the drain pipe can guide the condensate as it flows out of the first drip tray, effectively preventing splashing and avoiding the spread of condensate to the outer bottom wall of the first tray due to surface tension.

[0022] According to the present invention, in a hoisting machine, the distance between the bottom wall of the second water receiving tray and the second water receiving part gradually decreases along the direction closer to the first water receiving part; The bottom wall of the second water receiving tray has two mating guide surfaces. The distribution direction of the two guide surfaces is perpendicular to the extension direction of the drainage channel, and the mating position of the two guide surfaces corresponds to the drainage channel.

[0023] This design ensures that condensate in the second drip tray drains smoothly to the second drip section. It also prevents condensate from spreading to the outer bottom wall of the second drip tray due to surface tension.

[0024] According to the present invention, a drop-down machine is provided in which the angle between the evaporator body and the reference surface is greater than 45 degrees, and the reference surface is perpendicular to the longitudinal direction of the outer shell.

[0025] This design ensures that when the evaporator is placed vertically, the condensate on the outer surface of the evaporator body flows downwards along the outer surface of the evaporator body as much as possible, minimizing the possibility of the condensate dripping down the outer surface of the evaporator body during its downward flow.

[0026] The condenser provided by this utility model includes a housing, an evaporator, a main drip tray, and a secondary drip tray assembly. The evaporator is inclinedly disposed within the housing. The evaporator includes an evaporator body, branch pipes, and a main pipe. The main pipe is connected to the evaporator body via branch pipes to supply refrigerant output from the evaporator body. The main drip tray includes a first drip portion and a second drip portion. Along the vertical direction of the housing, the projected area of ​​the evaporator is located within the projected area of ​​the first drip portion. When the condenser is placed horizontally, the vertical direction of the housing is vertical, and the first drip portion of the main drip tray can collect condensate flowing from the surface of the evaporator body, as well as condensate dripping from the outer surfaces of the branch pipes and the main pipe. Along the longitudinal direction of the housing, the projected area of ​​at least one end of the evaporator body is located within the projected area of ​​the second drip portion. When the condenser is placed vertically, the longitudinal direction of the housing is vertical, and the second drip portion of the main drip tray can collect condensate flowing from the outer surface of the evaporator body. The auxiliary water receiving assembly includes a first water receiving tray and a second water receiving tray, which are located on the side of the evaporator body near the second water receiving section. The first water receiving tray is fitted over the outside of the main pipe. When the evaporator is placed vertically, the first water receiving tray is used to collect condensate flowing along the outer wall of the main pipe and condensate dripping from the outer surface of the main pipe. Along the longitudinal direction of the outer casing, the projection area of ​​the branch pipe is located within the projection area of ​​the second water receiving tray. When the evaporator is placed vertically, the second water receiving tray is used to collect condensate dripping from the outer surface of the branch pipe. This arrangement ensures that when the evaporator is placed horizontally, the first water receiving section of the main water receiving tray can collect condensate from the evaporator surface; when the evaporator is placed vertically, the second water receiving section of the main water receiving tray and the auxiliary water receiving tray assembly can collect condensate from the evaporator surface. When the drop-down unit is placed horizontally or vertically, it can effectively collect the condensate on the surface of the evaporator, thus meeting both horizontal and vertical installation requirements and solving the problem that drop-down units in related technologies cannot meet both horizontal and vertical installation requirements.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0041] The following is combined Figures 1 to 11 This invention describes the hoisting machine of this utility model.

[0042] like Figures 1 to 11 As shown, the hoisting machine provided in this embodiment of the present invention includes a housing 1, an evaporator 2, a main water receiving tray and an auxiliary water receiving tray assembly.

[0043] Specifically, the outer casing 1 has a horizontal, a vertical, and a lateral direction, with the horizontal direction of the outer casing 1 as a reference. Figure 1 The direction indicated by x in the middle is the longitudinal reference of outer shell 1. Figure 1 The direction indicated by y in the middle is the vertical reference of outer shell 1. Figure 1 The direction indicated by z. Any two of the longitudinal direction, the transverse direction, and the vertical direction of the outer casing 1 are perpendicular. When the hoist is placed horizontally, the vertical direction of the outer casing 1 is along the vertical direction. When the hoist is placed vertically, the longitudinal direction of the outer casing 1 is along the vertical direction.

[0044] The evaporator 2 is installed at an angle inside the outer casing 1. When the hoist is placed horizontally or vertically, the evaporator 2 has an angle with the vertical direction.

[0045] Evaporator 2 includes an evaporator body 3, branch pipes 4, and a main pipe 5. The main pipe 5 is connected to the evaporator body 3 via branch pipes 4 to supply refrigerant from the evaporator body 3. During operation, condensation forms on the outer surfaces of the evaporator body 3, branch pipes 4, and main pipe 5. The condensation on the outer surface of the evaporator body 3 flows down its surface. There are numerous branch pipes 4, each connected to the main pipe 5. The condensation on the outer surfaces of both branch pipes 4 and main pipe 5 flows down their surfaces towards lower positions. When the condensation accumulates and is substantial, it inevitably drips directly downwards.

[0046] The main water receiving tray includes a first water receiving part 7 and a second water receiving part 8.

[0047] Along the vertical direction of the outer casing 1, the projection area of ​​the evaporator 2 is located within the projection area of ​​the first water receiving part 7. When the hoist is placed horizontally, the vertical direction of the outer casing 1 is in the vertical direction, and the first water receiving part 7 of the main water receiving tray can collect the condensate flowing from the surface of the evaporator body 3 as well as the condensate dripping from the outer surfaces of the branch pipes 4 and the main pipe 5.

[0048] Along the longitudinal direction of the outer casing 1, at least one end of the evaporator body 3 is located within the projection area of ​​the second water receiving part 8. When the hoist is placed vertically, the longitudinal direction of the outer casing 1 is vertical, and the second water receiving part 8 of the main water receiving tray can collect the condensate flowing from the outer surface of the evaporator body 3.

[0049] The auxiliary water receiving assembly includes a first water receiving tray 9 and a second water receiving tray 10, which are located on the side of the evaporator body 3 near the second water receiving part 8. The main pipe 5 is located on the side of the branch pipe 4 near the first water receiving tray 9 and the second water receiving tray 10, and the condensate on the outer surface of the branch pipe 4 will gradually flow into the main pipe 5.

[0050] The first water receiving tray 9 is installed on the outside of the main pipeline 5. When the hoist is placed vertically, the first water receiving tray 9 is used to collect the condensate flowing along the outer wall of the main pipeline 5 and the condensate dripping from the outer surface of the main pipeline 5.

[0051] The second drip tray 10 is fixed inside the outer casing 1. Specifically, the second drip tray 10 can be fixedly connected to the side plate of the outer casing 1. Along the longitudinal direction of the outer casing 1, the projection area of ​​the branch pipe 4 is located within the projection area of ​​the second drip tray 10. When the hoist is placed vertically, the second drip tray 10 is used to collect the condensate dripping from the outer surface of the branch pipe 4.

[0052] With this configuration, when the evaporator is placed horizontally, the first water receiving part 7 of the main water receiving tray can collect the condensate on the surface of the evaporator 2. When the evaporator is placed vertically, the second water receiving part 8 of the main water receiving tray and the auxiliary water receiving tray assembly can collect the condensate on the surface of the evaporator 2. In both horizontal and vertical orientations, the evaporator can effectively collect the condensate on the surface of the evaporator 2, thus meeting the installation requirements for both horizontal and vertical installations. This solves the problem in related technologies where evaporator designs cannot meet these two installation requirements.

[0053] In this embodiment of the present invention, the first water receiving tray 9 includes a first tray body 11 and a sleeve 12.

[0054] A sleeve 12 is disposed inside the first tray 11 and penetrates the bottom wall of the first tray 11. The sleeve 12 is used for the main pipeline 5 to pass through, and the inner wall of the sleeve 12 is in sealed contact with the outer wall of the main pipeline 5 to prevent condensate flowing along the outer surface of the main pipeline 5 from entering between the sleeve 12 and the main pipeline 5. The condensate flowing along the outer surface of the main pipeline 5 will flow along the outer surface of the sleeve 12 to the first tray 11, and the first tray 11 is used to collect the condensate.

[0055] Along the longitudinal direction of the outer casing 1, the projection area of ​​the main pipe 5 is located within the projection area of ​​the first tray 11. The first drip tray can not only collect condensate flowing down the outer surface of the main pipe 5, but also collect condensate dripping down the outer surface of the main pipe 5.

[0056] In this way, the first water tray 9 can effectively collect the condensate on the outer surface of the main pipeline 5, which can effectively prevent the internal components of the hoist from rusting or short-circuiting due to the condensate on the outer surface of the main pipeline 5.

[0057] In this embodiment, the first water receiving tray 9 is made of an elastic material. Specifically, both the first tray body 11 and the sleeve 12 are made of elastic material, and both the first tray body 11 and the sleeve 12 are capable of elastic deformation. The elastic material can be, but is not limited to, rubber.

[0058] The sleeve 12 and the first disc 11 are formed with a slit 13, which penetrates the side wall of the sleeve 12, the bottom wall of the first disc 11 and the side wall of the first disc 11 along the axial direction of the sleeve 12.

[0059] With this configuration, when the first water receiving tray 9 is installed onto the main pipeline 5, a force can be applied to the positions of the first tray body 11 located on both sides of the cut 13, causing elastic deformation in the area near the cut 13. This increases the gap at the cut 13 position, aligning the gap at the cut 13 position with the main pipeline 5, allowing the first water receiving tray 9 to approach the main pipeline 5. This allows the main pipeline 5 to enter the sleeve 12 of the first water receiving tray 9 through the cut 13, thus fitting the first water receiving tray 9 onto the outside of the main pipeline 5 for easy installation.

[0060] At this time, the first water receiving tray 9 also includes a binding member, which is looped around the outside of the sleeve 12 (not shown in the figure). The binding member is used to fix the sleeve 12 to the main pipeline 5, so that the inner wall of the sleeve 12 is in sealed contact with the outer wall of the main pipeline 5. At the same time, the cut 13 position of the sleeve 12 is pressed tightly, so that the surfaces of the first water receiving tray 9 on both sides of the cut 13 are in close contact, reducing the gap at the cut 13 position, ensuring the integrity of the bottom wall of the first water receiving tray 9, and preventing condensate from leaking from the first water receiving tray 9.

[0061] In a further embodiment, a protrusion 14 is formed on the bottom wall of the first disc 11. The protrusion 14 extends radially along the sleeve 12, with one end extending to the outer wall of the sleeve 12 and the other end extending to the side wall of the first disc 11. A slit 13 is located at the top of the protrusion 14. Figure 11 As shown.

[0062] This design increases the difficulty of condensate in the first drip tray 9 overflowing outwards through the cut 13.

[0063] In a further embodiment, a flow guide is formed at the end of the sleeve 12 away from the first disc 11. The flow guide includes a flow guide cone 15 and two flow guide ramps 16.

[0064] The guide cone 15 is formed on the outer wall of the sleeve 12 away from the first disc 11. When the condensate flows downward along the outer surface of the main pipe 5 to the sleeve 12, it can flow downward quickly along the guide cone 15, avoiding the accumulation of condensate at the upper end of the sleeve 12 and reducing the possibility of leakage of condensate in the gap between the sleeve 12 and the main pipe 5.

[0065] Two guide slopes 16 are formed on the end face of the sleeve 12 away from the first disc 11, and both guide slopes 16 are inclined toward the central axis of the sleeve 12. When condensate flows downward along the outer surface of the main pipe 5 to the sleeve 12, it can gradually move away from the cut 13 at the end of the sleeve 12 along the guide slopes 16, reducing the accumulation of condensate at the cut 13 and thus reducing the possibility of condensate leakage at the cut 13 of the sleeve 12.

[0066] In this embodiment of the invention, the outer casing 1 has a bearing surface 21, and the bearing surface 21 has a connecting portion for connecting to the installation position when placed horizontally or vertically. The outer casing 1 has an air inlet grille 6 and an air outlet. The air inlet grille 6 is disposed on the side of the outer casing 1 opposite to the bearing surface 21. The air outlet is located at one longitudinal end of the outer casing, and the air outlet is located on the side of the evaporator away from the air inlet grille 6.

[0067] The bearing surface 21 is perpendicular to the vertical direction of the outer shell 1. Along the vertical direction of the outer shell 1, the first water receiving part 7 is located on the side of the evaporator body 3 away from the bearing surface 21, and the second water receiving part 8 is located on the side of the first water receiving part 7 close to the evaporator 2.

[0068] Along the longitudinal direction of the outer casing 1, the first water receiving tray 9, the second water receiving tray 10 and the second water receiving part 8 are all located on the side of the evaporator 2 away from the air outlet of the outer casing 1. The second water receiving tray 10 is located on the side of the first water receiving tray 9 away from the evaporator 2, and the second water receiving part 8 is located on the side of the second water receiving tray 10 away from the first water receiving tray 9.

[0069] When the hoist is placed horizontally, the bearing surface 21 is set in the horizontal direction, the bearing surface 21 is located above the evaporator 2, and the first water receiving part 7 is located below the evaporator 2.

[0070] When the hoist is placed vertically, the bearing surface 21 is set in the vertical direction. The second water receiving part 8, the first water receiving tray 9 and the second water receiving tray 10 are all located below the evaporator 2. The height of the second water receiving tray 10 is lower than the height of the first water receiving tray 9, and the height of the second water receiving part 8 is lower than the height of the second water receiving tray 10.

[0071] It should be noted that the portion of the main pipe 5 located on the side of the first water receiving tray 9 furthest from the evaporator 2 is wrapped with insulating cotton. The main pipe 5, now encased in insulating cotton, is no longer in contact with air and will not produce condensation. Furthermore, the insulating cotton has excellent thermal insulation properties; the temperature of its outer surface is the same as the temperature inside the outer casing 1, and higher than the temperature of the outer wall of the main pipe 5 and the dew point temperature of the air. Therefore, no condensation will form on the outer surface of the insulating cotton.

[0072] In a further embodiment, the bottom wall of the first water receiving tray 9 is provided with a drain hole, and the projection area of ​​the drain hole is located within the projection area of ​​the second water receiving tray 10 along the longitudinal direction of the outer casing 1. The condensate collected in the first water receiving tray 9 flows to the second water receiving tray 10 through the drain hole.

[0073] A drain groove 20 is provided at one end of the second water receiving tray 10 near the second water receiving part 8. Along the longitudinal direction of the outer casing 1, the projected area of ​​the drain groove 20 at least partially overlaps with the projected area of ​​the second water receiving part 8. Condensate in the second water receiving tray 10 flows to the second water receiving part 8 through the drain groove 20.

[0074] The main water receiving pan is equipped with a drain outlet 17, which is used to connect to the drainage system of the hoist so that the condensate in the main water receiving pan can be discharged outward.

[0075] With this configuration, the condensate in the secondary water receiving component is discharged outward through the main water receiving pan, eliminating the need for a separate drainage system for the secondary water receiving component. This design is simple and occupies little space.

[0076] The drain outlet 17 is located on the bottom wall of the second water receiving part 8, and the drain outlet 17 is located at the edge of the second water receiving part 8 near the first water receiving part 7, as shown in the figure. Figure 8 and Figure 9 With this configuration, condensate in the main drip tray can be drained promptly whether the hoist is placed horizontally or vertically, preventing condensate from accumulating in the main drip tray.

[0077] Two drain outlets 17 are provided, and the two drain outlets 17 are distributed laterally along the outer shell 1 at both ends of the second water receiving part 8 to improve the drainage efficiency of the main water receiving tray.

[0078] In this embodiment of the utility model, the first water receiving tray 9 has a drain pipe 18, which is disposed on the side of the first tray body 11 near the second water receiving tray 10. One end of the drain pipe 18 is connected to the drain hole, and the other end of the drain pipe 18 extends toward the second water receiving tray 10.

[0079] With this configuration, the drain pipe 18 can guide the condensate as it flows out of the first water receiving tray 9, effectively preventing splashing of the condensate and avoiding the problem of condensate spreading to the outer bottom wall of the first tray 11 due to the surface tension of the condensate.

[0080] In a further embodiment, the distance between the bottom wall of the second water receiving tray 10 and the second water receiving part 8 gradually decreases along the direction closer to the first water receiving part 7. That is, the second water receiving tray 10 is tilted, with the end of the second water receiving tray 10 furthest from the first water receiving part 7 having a larger height and the end of the second water receiving tray 10 closest to the first water receiving part 7 having a smaller height. Specifically, this can be achieved by tilting the second water receiving tray 10 as a whole.

[0081] This ensures that the condensate in the second drip tray 10 can be smoothly discharged to the second drip section 8. It also prevents the condensate from spreading to the outer bottom wall of the second drip tray 10 due to surface tension.

[0082] In some embodiments, the inner bottom wall of the second water receiving tray 10 can be configured to be inclined in multiple directions. When the hoist is placed vertically, the height of the drainage trough 20 is lower than the height of any position on the inner bottom wall of the second water receiving tray 10.

[0083] Specifically, the inner bottom wall of the second water receiving tray 10 includes two guide surfaces 19. The distribution direction of the two guide surfaces 19 is perpendicular to the extension direction of the drainage trough 20, and the docking position of the two guide surfaces 19 corresponds to the drainage trough 20. The guide surfaces 19 are inclined. When the hoist is placed vertically, the height of the ends of the two guide surfaces 19 that are far apart is greater than the height of the ends of the two guide surfaces 19 that are close together, so that the condensate water gathers at the docking position of the two guide surfaces 19 and flows into the drainage trough 20.

[0084] In this embodiment of the invention, the surface perpendicular to the longitudinal direction of the outer shell 1 is used as the reference surface, so that the angle between the evaporator body 3 and the reference surface is greater than 45 degrees.

[0085] When the evaporator is placed horizontally, the downward projection area of ​​the evaporator 2 is entirely within the downward projection area of ​​the first water receiving part 7 of the main water receiving tray. Even if condensate on the surface of the evaporator body 3 drips down, it will drip into the first water receiving part 7 of the main water receiving tray. However, when the evaporator is placed vertically, only the downward projection area of ​​the lowest part of the evaporator body 3 is within the downward projection area of ​​the second water receiving part 8 of the main water receiving tray. If condensate on the surface of the evaporator body 3 drips down, it may drip outside the second water receiving part 8 of the main water receiving tray. In this embodiment, by making the angle between the evaporator body 3 and the reference plane greater than 45 degrees, when the evaporator is placed vertically, the condensate on the outer surface of the evaporator body 3 can flow downward along the outer surface of the evaporator body 3 as much as possible, minimizing the possibility of condensate dripping down the outer surface of the evaporator body 3 during downward flow.

[0086] Specifically, the angle between the evaporator body 3 and the reference plane can be 51 degrees.
