[0016] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figures 1-6 As shown, a drainage monitoring structure is applied to an air conditioner, the air conditioner including a bottom frame 1, the bottom frame 1 having a water outlet chamber 2, the monitoring structure including: Mounting box 3 is suspended on one side of the water outlet cavity 2. The mounting box 3 has a mounting cavity 31 that is closed on all four sides and open at one end. The electronic control component 4 is located on the bottom frame 1; A water level monitoring device is disposed between the mounting box 3 and the electronic control component 4. The water level monitoring device includes a printed circuit board 5, a water level sensor 6 and a wire 7. The water level sensor 6 is disposed on the printed circuit board 5. One end of the wire 7 is connected to the printed circuit board 5 and the other end is connected to the electronic control component 4. The mounting box 3 is provided with a slide rail 32, and the printed circuit board 5 is disposed in the mounting cavity 31 via the slide rail 32.

[0017] In this embodiment, the bottom frame 1 of the air conditioner is provided with a water outlet cavity 2, which has a water outlet that communicates with the outside. To facilitate the monitoring of the water level in the water outlet cavity 2, an installation box 3 is provided on the bottom frame 1. The installation box 3 is installed on the side of the water outlet cavity 2 with the highest water level. The electronic control component 4 is provided on one side of the bottom frame 1. A water level monitoring device is provided between the electronic control component 4 and the installation box 3. The water level monitoring device includes a printed circuit board 5, a water level sensor 6, and a wire 7. The water level sensor 6 is provided on the printed circuit board 5. One end of the wire 7 is connected to the printed circuit board 5, and the other end is electrically connected to the electronic control component 4. The installation box 3 is provided with a slide rail 32. The printed circuit board 5 can be secured in the installation cavity 31 by using the slide rail 32 through the open end of the installation box 3, which facilitates production assembly and later maintenance. The printed circuit board 5 can be quickly disassembled and assembled, improving maintenance efficiency. When the outlet is blocked, the water level in the outlet chamber 2 can be monitored in real time. When the water level reaches a certain height, the water level sensor 6 transmits a signal to the electronic control component 4, which then automatically shuts down the air conditioner and displays a corresponding prompt icon on the air conditioner's display screen (this is existing technology and will not be described in detail here, such as publication number CN221525080U, titled "Control Circuit for a Split-Type Air Conditioner Condensate Drain Pump"). The water level monitoring sensor is a non-contact sensor, model XKC-C389, which can detect changes in dielectric constant and can penetrate non-metallic container walls up to 20mm thick. It can detect the condensate water level in real time, indirectly sensing the water level by detecting the outer wall of the container, avoiding direct contact with the condensate water and extending its service life.

[0018] The mounting box 3 is provided with a detachable mounting cover 8, which covers the opening end of the mounting cavity 31.

[0019] In this embodiment, the mounting cover 8 closes the opening end of the mounting cavity 31 to prevent foreign objects from falling into the mounting cavity 31 through the open end, and also helps to form a complete space with the mounting cavity 31 to prevent moisture.

[0020] The mounting cover 8 is provided with a wire passage groove 81 that communicates with the mounting cavity 31, for avoiding the wire 7.

[0021] In this embodiment, in order to prevent the wire 7 from being squeezed or even pinched when the mounting plate is closed, a wire passage groove 81 connected to the mounting cavity 31 is provided on the mounting cover 8. The wire passage groove 81 provides a passage for the wire 7 to avoid the wiring, making the wiring more regular and ensuring the effective closure of the sealing cover plate, thus maintaining the sealing of the mounting cavity 31.

[0022] The mounting cover 8 is provided with two limiting posts 9, and the bottom of the mounting cavity 31 is provided with two limiting ports that communicate with the slide rail 32. The limiting posts 9 protrude from the limiting ports through the slide rail 32 to cooperate with the mounting cavity 31 to form a limiting cavity 12 for mounting the printed circuit board 5.

[0023] In this embodiment, the two slide rails 32 primarily address the guidance issue in the X-axis direction. However, the printed circuit board 5 may still have some wobbling space in the Y and Z axis directions (width and height). The limiting post 9, in conjunction with the bottom of the mounting cavity 31, forms a limiting cavity 12, constituting a three-sided surrounding positioning structure. This ensures that after the printed circuit board 5 is inserted, its position in all directions—front-back, left-right, and up-down—is precisely limited, eliminating any potential loosening or displacement and guaranteeing the accuracy of the water level sensor 6's position. During air conditioning operation, the compressor, fan, and other components generate vibrations. Impacts are also inevitable during transportation and installation. Under prolonged vibration, the ordinary slide rail 32 structure may gradually loosen the module. The limiting cavity 12, however, tightly confines the printed circuit board 5 within the mounting cavity 31, significantly enhancing the overall mechanical stability of the module and effectively preventing connector loosening, component damage, or detection inaccuracies caused by vibration.

[0024] The limiting post 9 is made of elastic material, and the two limiting posts 9 extend in opposite directions.

[0025] In this embodiment, the two limiting posts 9 extend in opposite directions, causing one limiting post 9 to tilt to the left and the other to tilt to the right, forming a barbed structure. During installation, the printed circuit board 5 is abutted against the end face of the mounting cover 8 and the wire 7 is clamped in the wire groove 81. The two limiting posts 9 are moved slightly towards each other and clamp the opposite end faces of the printed circuit board 5. Then, the limiting posts 9 are continuously pressed so that they slide along the slide rail 32 of the mounting cavity 31 to the bottom. The two limiting posts 9 abut against the corresponding slide rail 32. Since the extension directions are opposite, they apply elastic pressure to the printed circuit board 5 from both sides and restrict the printed circuit board 5 in the limiting cavity 12 to prevent it from being displaced due to vibration.

[0026] Rubber pads are provided on the inner wall of the mounting cavity 31 and the surface of the limiting post 9.

[0027] In this embodiment, a rubber pad (not shown) is provided on the inner wall of the mounting cavity 31. Specifically, rubber pads are added at the two slide rails 32 to facilitate elastic contact with the two limiting posts 9, making it easier for the limiting posts 9 to be inserted into the mounting cavity 31 during installation. Adding rubber pads to the surface of the limiting posts 9 not only facilitates slight clearance of the slide rails 32 during installation, but also provides a stronger clamping force compared to purely elastic plastic limiting posts 9, further preventing the printed circuit board 5 from undergoing slight displacement under vibration.

[0028] The end of the limiting post 9 away from the mounting cover 8 is provided with a hook 10, and the hook 10 extends in a direction away from the limiting post 9.

[0029] In this embodiment, hooks 10 are provided on both limiting posts 9. The hooks 10 extend in opposite directions. When the mounting cover 8 and the printed circuit board 5 are inserted together along the slide rail 32 with the limiting post 9, after the limiting post 9 extends out of the mounting cavity 31, the limiting post 9 undergoes elastic deformation, causing the two hooks 10 to lock the bottom edge of the mounting box 3 to prevent the mounting cover 8 from separating from the mounting box 3.

[0030] The hook 10 is provided with a guide surface 11 that gradually slopes from bottom to top, and the guide surface 11 slides in cooperation with the slide rail 32.

[0031] In this embodiment, by setting a guide surface 11 on the hook 10, the limiting post 9 does not need to use a large vertical force to push against the slide rail 32 when it is inserted, which would make the operation stiff and prone to jamming. The inclined guide surface 11 converts the vertical pushing force into an inclined component force. When the limiting post 9 is pushed horizontally along the slide rail 32, the resistance of the entire insertion process is reduced, and the assembly process is optimized.

[0032] This embodiment also provides an air conditioner, including the drainage monitoring structure described above. The specific structure of the air conditioner is the same as described in the above embodiment. Since this air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
