In other instances, well-known structures and processes are not elaborated as they would

[0058] Air conditioners are almost one of the essential household appliances in modern families, which are used to create a comfortable indoor environment for users in cold winter or hot summer. The air conditioner indoor unit will produce a large amount of condensate water during the working process, so it is necessary to use a drainage pump and pipeline to drain the generated condensate water;

[0059] And in the water pump device, generally a water level switch is provided, and during the installation process of the water level switch or the maintenance process, due to the limited space in the water pump box, the operation of the nut on the water level switch is not convenient, which leads to the difficulty of installation or replacement of the water level switch.

[0060] For this purpose, please refer to Figure 1 and Figures 4 to 8 The present application provides a mounting structure of a water level switch 10, which is used for mounting the water level switch 10, comprising a mounting plate 22 and a limiting structure 30, the mounting plate 22 is provided with a mounting hole 23 penetrating along the thickness direction thereof, the mounting hole 23 is used for mounting the mounting rod part 11 of the water level switch 10; the limiting structure 30 is arranged on one side of the mounting plate 22 in the thickness direction thereof, which is used for limiting the rotation of the nut on the mounting rod part 11 of the water level switch 10 when the mounting rod part 11 of the water level switch 10 is mounted in the mounting hole 23.

[0061] It should be noted that for the water level switch 10, two nuts are generally arranged thereon, and the two nuts are used to clamp the two sides of the mounting plate 22 in the thickness direction, so as to realize the positioning of the water level switch 10. The limiting structure 30 can limit the rotation of one of the two nuts, or can limit the rotation of both of the two nuts. In this embodiment, the limiting of the rotation of one of the two nuts is not limited. When the rotation of one of the two nuts is limited, the installer can first insert the mounting rod part 11 of the water level switch 10 into the mounting hole 23 during the installation process, and one of the two nuts is limited by the limiting structure 30. At this time, the installer only needs to screw the other nut, so as to adjust the distance between the two nuts, so that the two nuts clamp the mounting plate 22, thereby realizing the installation of the water level switch 10. When the limiting structure 30 limits the rotation of both of the two nuts, the installer can rotate the mounting rod part 11, so as to realize the disassembly or debugging of the water level switch 10.

[0062] The embodiment of the present application sets the limiting structure 30 on the mounting plate 22, so that the limiting structure 30 replaces the conventional wrench to limit the rotation of the nut on the water level switch 10, and the nut does not need to be operated in a narrow space by using a wrench, thereby improving the convenience of the installation of the water level switch 10.

[0063] In addition, in order to facilitate the water level switch 10 to enter and exit the mounting hole 23, please refer to Figure 9 In an embodiment, the mounting plate 22 has a first end and a second end arranged opposite in a first direction, the first direction is perpendicular or inclined to the thickness direction of the mounting plate 22, the first end of the mounting plate 22 is used to be fixedly installed to the water pump box 20, and the mounting hole 23 extends to the second end of the mounting plate 22 along the first direction, so as to form an opening 24 at the second end of the mounting plate 22.

[0064] It should be noted that when the opening 24 is not arranged, the installer can only insert the mounting rod part 11 into the mounting hole 23, and then set the nuts on the mounting rod part 11. When the two nuts are arranged on the mounting rod part 11, the nuts will interfere with the mounting plate 22 during the insertion of the mounting rod part 11, so that the two nuts cannot be arranged on the two sides of the mounting plate 22 in the thickness direction. Therefore, the installation process of the water level switch 10 is relatively complicated.

[0065] In the scheme of the embodiment, by setting the through opening 24, the installer can first fit two nuts on the mounting rod portion 11 during installation, and then place the mounting rod portion 11 into the mounting hole 23 through the through opening 24 in the first direction. At this time, the two nuts can be arranged on both sides of the thickness direction of the mounting plate 22, and one of the nuts is limited and stopped by the limiting structure 30. Then, the nut is screwed, and the assembly of the water level switch 10 is completed. In this process, since the mounting rod portion 11 is completed, the two nuts are already fitted on the mounting rod portion 11. Therefore, in the subsequent process, only the position of the nut needs to be adjusted, avoiding excessive operation of the nut in a limited space, and improving the convenience in the installation process.

[0066] It should be emphasized that the specific implementation form of the limiting structure 30 is not limited, which can be in the form of multiple limiting protrusions, for example, multiple limiting protrusions are arranged to form a limiting channel that is adapted to the shape of the nut. When the nut is placed in the limiting channel, it can be limited by the limiting protrusions, so that it cannot rotate. It can also be that a corresponding limiting groove is formed on one side of the mounting plate 22, etc., which is not limited here.

[0067] In an embodiment, please refer to Figure 9 The limiting structure 30 includes multiple ribs arranged in the first direction; multiple ribs can abut the outer circumferential side of the nut to interfere with the nut when the nut is about to rotate, so as to stop the rotation of the nut.

[0068] Moreover, the limiting structure 30 is composed of multiple ribs in the same direction, which can facilitate the inclined ejection during the demolding of the mounting plate 22, so that it can be smoothly demolded.

[0069] Specifically, the specific implementation form of the multiple ribs limiting the nut is not limited, which can be that the multiple ribs include two first ribs 31 arranged in the second direction, the second direction is perpendicular or inclined to the first direction, and the interval between the two first ribs 31 forms a clamping channel 32 for clamping the two sides of the nut in the second direction.

[0070] In this way, since the first rib 31 extends in the first direction, the nut can enter and exit the clamping channel 32 in the first direction. When the nut is located in the clamping channel 32, if the nut wants to rotate, it will be stopped due to the abutment of the two first ribs 31.

[0071] In addition, the plurality of ribs can comprise two second ribs 33 arranged in a second direction, the second direction being perpendicular or inclined to the first direction, and one end of the two second ribs 33 being arranged to abut two edges of one corner of the nut, so that the two second ribs 33 can limit the rotation of the one corner of the nut.

[0072] Of course, the plurality of ribs can comprise two first ribs 31 and two second ribs 33 at the same time, and in this case, the two second ribs 33 are arranged in the clamping channel 32, so that the two first ribs 31 can limit the two sides of the nut in the second direction, and the two second ribs 33 can limit the rotation of one corner of the nut, and the limiting effect of the nut is better.

[0073] Please refer to Figures 1 to 5 The utility model also provides a water pump device 100 which is used in an air conditioner, the water pump device 100 comprises a water pump box 20, a pump body 60, the installation structure of water level switch 10 and water level switch 10, the installation cavity 21 is formed in the water pump box 20, the pump body 60 is arranged in the installation cavity 21, the installation structure of water level switch 10 is installed in the installation cavity 21, and the water level switch 10 comprises an installation rod part 11 and a nut sleeved on the installation rod part 11, and the specific structure of the installation structure of water level switch 10 is referred to the above embodiment, because the water pump device 100 adopts all the technical schemes of the above all embodiments, so it has all the beneficial effects of the technical schemes of the above embodiments, and here is not repeated.

[0074] In the technical scheme of the embodiment, the installation structure of water level switch 10 is arranged in the water pump device 100, and the limiting structure 30 is arranged on the installation plate 22, so that the limiting structure 30 replaces the conventional wrench to stop the rotation of the nut on the water level switch 10, and the wrench is not needed to operate the nut in a narrow space, so that the installation of the water level switch 10 is convenient.

[0075] Specifically, the specific implementation form of the water level switch 10 is not limited, can be inductive water level switch 10, for example infrared ranging type, can also be float type water level switch 10, etc., which is not limited, in an embodiment, the water level switch 10 is a float type water level switch 10.

[0076] It should be noted that the water level switch 10 can be provided with only one nut, or can be provided with multiple nuts. When multiple nuts are provided, the limiting structure 30 can limit rotation of only one of the nuts, or can limit rotation of multiple nuts. In this embodiment, the limiting structure 30 limits rotation of multiple nuts. During disassembly of the water level switch 10, the installation rod portion 11 can be rotated to achieve the disassembly, which is relatively cumbersome.

[0077] Further, in some embodiments, the installation plate 22 of the installation structure of the water level switch 10 has a first side and a second side arranged opposite in the thickness direction thereof. The water level switch 10 includes at least a first nut 12 and a second nut 13 sleeved on the installation rod portion 11. The first nut 12 and the second nut 13 are arranged on the first side and the second side of the installation plate 22, respectively, and are clamped on the installation plate 22 together. The limiting structure 30 of the installation structure of the water level switch 10 is arranged on the second side of the installation plate 22 to limit rotation of the second nut 13.

[0078] According to the technical scheme of the present embodiment, the first nut 12 and the second nut 13 are arranged to be clamped on the installation plate 22 together, thereby achieving fixed installation of the water level switch 10. The limiting structure 30 of the installation structure of the water level switch 10 is arranged on the second side of the installation plate 22 to limit rotation of the second nut 13. When the water level switch 10 needs to be disassembled, the first nut 12 can be rotated by a wrench to cause relative rotation between the first nut 12 and the installation rod portion 11, thereby changing the distance between the first nut 12 and the second nut 13, and achieving disassembly of the water level switch 10. During the entire disassembly process, the installation rod portion 11 does not need to be rotated, and the operation is simple.

[0079] In addition, the second nut 13 can be movably sleeved on the installation rod portion 11, or can be fixedly sleeved on the installation rod portion 11. In this embodiment, the second nut 13 is movably sleeved on the installation rod portion 11. When the second nut 13 is movably sleeved on the installation rod portion 11, the position of the water level switch 10 in the thickness direction of the installation plate 22 can be adjusted by rotating the installation rod portion 11.

[0080] In an embodiment, the installation rod portion 11 is fixedly connected with the second nut 13. When the limiting structure 30 limits rotation of the second nut 13, the limiting structure 30 also limits rotation of the installation rod portion 11. During installation, the installer only needs to screw the first nut 12.

[0081] Specifically, the fixed connection between the two has many ways, for example, using welding, bonding, clamping and other forms, in an embodiment, the mounting rod part 11 and the second nut 13 are integrally arranged, so that the two are produced together, which can reduce the production cost and increase the strength of the mounting rod part 11 to avoid deformation.

[0082] Further, the water pump box 20 is not limited in specific implementation, which can be integrally arranged or separately arranged, which is not limited here.

[0083] In an embodiment, the water pump box 20 includes a first box body 25 and a second box body 26 arranged in a detachable manner.

[0084] In the technical scheme of the embodiment, by arranging the water pump box 20 as a first box body 25 and a second box body 26 arranged in a detachable manner, the pump body 60 and the water level switch 10 and other components can be installed in the first box body 25 and the second box body 26, and then the first box body 25 and the second box body 26 are installed and assembled into the water pump box 20, which simplifies the installation process of the water pump device 100.

[0085] At this time, the mounting plate 22 can be mounted on the first box body 25 or the second box body 26, which is not limited here, in an embodiment, the pump body 60 is mounted on the first box body 25, and the mounting plate 22 is mounted on the second box body 26, so that the water level switch 10 and the pump body 60 are arranged in two boxes, thereby avoiding mutual interference during installation.

[0086] It should be emphasized that the specific installation method of the pump body 60 is not limited, which can be screwed or limited by the limiting ribs, please refer to Figure 12 In an embodiment, the pump body 60 and the first box body 25 are assembled by three limiting ribs 73, after the pump body 60 is placed in the limiting rib 73, the positioning is accurate, and then three bolts are fixed, here, the buckle is not used, which is considered that the buckle has poor reliability during long-term operation and vibration of the pump body 60, so three screws are used for fixation.

[0087] At this time, the first side of the mounting plate 22 can be arranged towards the first box body 25 or the second box body 26, which is not limited here, it can be understood that if the second side of the mounting plate 22 is arranged towards the first box body 25, the user will also be limited by the space in the second box body 26 when operating the first side of the mounting plate 22, thereby existing a certain degree of inconvenience.

[0088] Therefore, in an embodiment, the first side of the mounting plate 22 is arranged towards the first box 25, at this time, the first side of the mounting plate 22 is also arranged towards the open end of the second box 26, therefore, the installer can operate the first side of the mounting plate 22 from the open end of the second box 26, without being restricted by the space of the second box 26, at this time, the installer only needs to screw the first nut 12 on the first side of the mounting plate 22 during the whole installation process, so as to complete the disassembly and assembly of the water level switch 10, and the operation is the most convenient.

[0089] Further, in order to realize the convenience of disassembly and assembly of the first box 25 and the second box 26, please refer to Figure 1 、 Figure 10 and Figures 11 to 14 , the first box 25 and the second box 26 are provided with a plurality of clamping structures along the circumferential side, so that the first box 25 and the second box 26 are clamped and matched between each other, and are fixed and installed.

[0090] Specifically, the clamping structure includes a clamping portion 27 arranged on the second box 26 and a matching portion 28 arranged on the first box 25, so that the first box 25 and the second box 26 are detachably connected through the clamping and matching between the clamping portion 27 and the matching portion 28.

[0091] It should be noted that the specific implementation form of the clamping structure is not limited, which can be in the form of a clamping convex and a clamping groove, or in the form of a plurality of buckles, etc., which is not limited here.

[0092] In addition, the first box 25 can be provided with a first threaded hole portion, and the second box 26 can be provided with a second threaded hole portion corresponding to the first threaded hole portion, the first threaded hole portion and the second threaded hole portion have the same extension direction, and at least one of them is arranged as a through hole, so that in the actual installation process, the user only needs to align the first threaded hole portion and the second threaded hole portion, and then pass the threaded hole portion arranged as a through hole through the screw, and then extend into the other threaded hole portion, so as to connect the first box 25 and the second box 26 through the threaded connection.

[0093] Of course, the clamping structure and the threaded hole portion can also be arranged at the same time, at this time, the first box 25 and the second box 26 can be first coarsely positioned through the clamping structure, and then strongly positioned through the screw, so as to improve the connection strength of the first box 25 and the second box 26.

[0094] In addition, please refer toFigure 3 In order to prevent the wiring of the pump body 60 from interfering with the detection of the water level switch 10, in an embodiment, a first wire passing hole 49 is formed in the first box body 25 to communicate the inside and outside of the mounting cavity 21, and the wire harness of the pump body 60 is arranged to pass through the first wire passing hole 49. In this way, the wiring and mounting of the pump body 60 are both arranged on the first box body 25, so that interference with the water level switch 10 in the second box body 26 can be avoided.

[0095] Alternatively, the second box body 26 is formed with a second wire passing hole 50, and the wire harness of the water level switch 10 is arranged to pass through the second wire passing hole 50. In this way, the wire harness of the water level switch 10 and the water level switch 10 are both mounted on the second box body 26, so that interference with the water pump can be avoided.

[0096] Of course, both can also be arranged at the same time. In this case, during the mounting process, the pump body 60 and the water level switch 10 are independent of each other, the wiring is simple and clear, and mutual interference between the two can be avoided.

[0097] Further, the specific implementation form of the first wire passing hole 49 and / or the second wire passing hole 50 is not limited, which can be in the form of a direct through hole, or in the form of a plurality of hole segments, etc., which is not limited here.

[0100] Similarly, the second wire passing hole 50 can also be formed in the form of a wire passing groove and an avoiding groove, so as to facilitate the installation of the wire harness, and after the installation is completed, the first box body 25 and the second box body 26 can clamp the wire harness and prevent the wire harness from moving.

[0101] In addition, in some embodiments, referring to Figure 4 、 4 and 6, the bottom of the second box body 26 is sunken at the water inlet 62 of the pump body 60 to form a water storage groove 47 at the bottom of the second box body 26; the bottom of the second box body 26 is also provided with a water guide inclined surface 48 inclined towards the water storage groove 47.

[0102] In the technical scheme of the embodiment, the water in the second box body 26 can be guided into the water storage groove 47 by the water storage groove 47 and the water guide inclined surface 48, facilitating the suction of the water pump and avoiding the phenomenon of backflow.

[0103] It should be noted that the surface on which the water inlet 62 of the pump body 60 is located should be lower than the surface composed of the lowest point of the water guide inclined surface 48, and the distance m from the surface on which the water inlet 62 of the pump body 60 is located to the bottom surface of the water storage groove 47 is greater than or equal to 3 mm. If the distance is too small, the pump body 60 is prone to be blocked by dirt.

[0104] In addition, an anti-backflow step 61 can be arranged in the second box body 26 for the water inlet 62. When the water level is low, the anti-backflow step 61 can prevent the water in the water pump box 20 from flowing back to the hose 63 or the water receiving disc.

[0105] It can be understood that when the temperature is below zero in the cold winter night, the residual water of the water pump will freeze in the pump body 60, causing the water pump device 100 to be unable to start, and even starting in the frozen state will burn the motor wire package and damage the water pump, affecting people's normal life.

[0106] Therefore, referring to Figure 5 and Figure 7 , in an embodiment, the outer surface of the water pump box 20 is provided with a heat preservation structure, so that by arranging the heat preservation structure, on the one hand, the water pump device 100 can be kept warm to avoid freezing in the cold environment.

The three pieces of heat preservation sponge can be made of XPE, PE or EPDM, etc. Since the second box body 26 is designed as a cuboid, the first heat preservation cotton 70 on the side can be selected as a rectangular sponge to surround and stick. After sticking, the second box body 26 has regular sponge on the side and the bottom, and the process holes, grooves, injection molding defects, etc. on the second box body 26 cannot be seen, and the appearance is beautiful.

[0108] In addition, referring to Figure 1 , 9 and 10, when the first box body 25 and the second box body 26 are provided with threaded hole portions, in order to ensure the strength of the threaded hole portions and the ejection requirement, the two sides of the second box body 26 need to be subjected to glue digging treatment, and after the glue digging treatment, there are large grooves, which are not beautiful. The first heat preservation cotton 70 can wrap the second box body 26 from the side to cover the two large grooves, so as to ensure the integrity and beauty of the appearance.

[0109] In addition, in order to facilitate the installation of the water pump device 100, a level installation groove is formed in the top of the water pump box 20, and the level is pasted in the installation groove through double-sided adhesive.

[0110] Referring to Figure 2 and Figure 15 , a limiting round hole 75 is designed below the hook 74 of the top cover 4 of the water pump box 20. During installation, the limiting round hole 75 of the upper cover of the water pump box 20 is sleeved into the lifting rod, and then the position of the water pump box 20 is adjusted through the horn opening of the hook 74, and the lifting rod nut is tightened. The hook 74 on the other side is reserved for use, which is suitable for complex and changeable installation environment.
