Abstract
Description
Technical Field
[0001] This utility model relates to the field of dehumidifier technology, and in particular to a dehumidifier water pan level monitoring device. Background Technology
[0002] As a commonly used air conditioning device, the dehumidifier works by drawing humid air into the machine through a fan. After being processed by a heat exchanger, the moisture in the air is condensed into water droplets and finally collected in the water tank. The dry air is then discharged outside the machine. The water level control is directly related to the safety and stability of the dehumidifier's operation. Current dehumidifier water pan level monitoring devices still have the following problems: Most dehumidifier water pan level monitoring devices use a single liquid level sensor for water level monitoring, which affects the monitoring accuracy and stability, making it difficult to achieve precise control of multiple water level gradients and fault redundancy protection, and leading to problems such as misjudgment, water level overflow or equipment malfunction. Summary of the Invention
[0003] The purpose of this invention is to provide a dehumidifier water pan level monitoring device, which solves the problem that most existing dehumidifier water pan level monitoring devices use a single liquid level sensor for water level monitoring, thus affecting the monitoring accuracy and stability.
[0004] To achieve the above objectives, a dehumidifier water pan level monitoring device is provided, including an installation component and a monitoring component. The installation component includes a dehumidifier water tank, an inlet pipe, a water receiving pan, a water pump, and a delivery pipe. The monitoring components include an early warning water level sensor, a mounting shell, a connecting rod, a float, a warning water level sensor, a photoelectric liquid level sensor, a mounting groove, a magnet, a Hall sensor, a slide, and a fixing rod.
[0005] Preferably, the dehumidifier water tank is provided with a water inlet pipe, and a water receiving tray is fixedly installed at the upper end of the water inlet pipe.
[0006] Preferably, a water pump is installed at the bottom of one side of the dehumidifier's water tank, and a delivery pipe is installed on the water pump.
[0007] Preferably, a mounting shell is fixedly installed in the middle of one side of the dehumidifier water tank, and warning water levels are provided at both ends of the mounting shell on one side of the dehumidifier water tank.
[0008] Preferably, a Hall sensor is fixedly installed at the top of the mounting housing, and the Hall sensor is at the same horizontal level as the warning water level. Sliding grooves are provided on both sides of the mounting housing.
[0009] Preferably, a connecting rod is slidably mounted on the mounting shell, a float is fixedly mounted on the bottom of the connecting rod, and a mounting groove is opened at the upper end of the connecting rod, in which a magnet is fixedly mounted.
[0010] Preferably, a fixing rod is fixedly installed on both sides of the connecting rod, and the fixing rod is slidably installed in the slide groove.
[0011] Preferably, a photoelectric liquid level sensor is fixedly installed in the middle of the other side inside the mounting housing. Warning water levels are set at both ends of the photoelectric liquid level sensor on the other side inside the mounting housing. The photoelectric liquid level sensor and the warning water level are at the same horizontal line. The warning water level is located above the warning water level. The photoelectric liquid level sensor, Hall sensor and water pump are all electrically connected to the controller.
[0012] The above-mentioned solution has the following beneficial effects: This patent achieves graded monitoring of warning and alert water levels by setting up an integrated Hall sensor and photoelectric liquid level sensor mounting shell, as well as a float with magnets, a fixing rod, and a connecting rod structure. The sliding stability of the float is improved by the guide chute, which greatly reduces the risk of false triggering. At the same time, the non-contact sensing of the Hall sensor and magnet and the accurate detection of the photoelectric liquid level sensor form a double protection. Combined with the linkage with the controller and water pump, it ensures timely drainage when the water level exceeds the warning level, improving the reliability of monitoring and the safety of equipment operation.

Detailed Implementation
[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0017] Reference Figure 1 This utility model discloses a dehumidifier water tank level monitoring device, including an installation component 1. The installation component 1 includes a dehumidifier water tank 11, an inlet pipe 12, a water receiving tray 13, a water pump 14, and a delivery pipe 15. The inlet pipe 12 is installed on the dehumidifier water tank 11, and the water receiving tray 13 is fixedly installed at the upper end of the inlet pipe 12. The water pump 14 is installed at the bottom of one side of the dehumidifier water tank 11, and the delivery pipe 15 is installed on the water pump 14. In use, the dehumidifier water tank 11 provides a reliable carrier for water storage. The inlet pipe 12 directs condensate water into the dehumidifier water tank 11. The water receiving tray 13 expands the condensate water receiving range and ensures water inlet stability. The cooperation of the water pump 14 and the delivery pipe 15 ensures timely discharge of excess water. Overall, [the device is designed to effectively manage water levels]. This design ensures normal water storage and drainage circulation in the dehumidifier's water tray, preventing water overflow or poor drainage caused by unreasonable foundation structure layout. Through the cooperation of the inlet pipe 12 and the water tray 13, the condensate produced by the dehumidifier can be accurately collected into the water tray 13 and then flow into the dehumidifier's water tank 11 through the inlet pipe 12, preventing condensate leakage from contaminating the equipment or the environment. The water pump 14 is set at the bottom of one side of the dehumidifier's water tank 11, and together with the delivery pipe 15, it can efficiently pump out the water accumulated in the water tank, ensuring that the water accumulated at the bottom of the dehumidifier's water tank 11 can be fully discharged, reducing the risk of residual water stains breeding bacteria. At the same time, the bottom installation position makes it less likely for the water pump 14 to run dry when starting, extending the service life of the equipment and improving the stability and reliability of the dehumidifier's water level control. Reference Figure 2 - Figure 4This utility model embodiment of the dehumidifier water pan level monitoring device includes a monitoring component 2, which includes a warning water level 21, a mounting shell 22, a connecting rod 23, a float 24, a warning water level 25, a photoelectric liquid level sensor 26, a mounting groove 27, a magnet 28, a Hall sensor 29, a sliding groove 210, and a fixing rod 211. The mounting shell 22 is fixedly installed in the middle of one side of the dehumidifier water pan 11. Warning water levels 21 are provided at both ends of the mounting shell 22 on one side of the dehumidifier water pan 11. A Hall sensor 29 is fixedly installed at the top of the mounting shell 22, and the Hall sensor 29 is at the same horizontal line as the warning water level 21. Sliding grooves 210 are provided on both sides of the mounting shell 22, allowing the mounting shell 22 to slide... A connecting rod 23 is installed, with a float 24 fixedly installed at the bottom of the connecting rod 23. A mounting groove 27 is provided at the upper end of the connecting rod 23, and a magnet 28 is fixedly installed within the mounting groove 27. Fixing rods 211 are fixedly installed on both sides of the connecting rod 23, and the fixing rods 211 are slidably installed within a sliding groove 210. A photoelectric liquid level sensor 26 is fixedly installed in the middle of the other side of the mounting housing 22. Warning water levels 25 are provided at both ends of the photoelectric liquid level sensor 26 on the other side of the mounting housing 22. The photoelectric liquid level sensor 26 and the warning water levels 25 are at the same horizontal line, and the warning water levels 25 are located above the warning water level 21. The photoelectric liquid level sensor 26, the Hall sensor 29, and the water pump 14 are all electrically connected to the controller. In use, the Hall sensor 29 and photoelectric level sensor 26 are integrated into the mounting housing 22, forming a graded monitoring structure with components such as the float 24 and connecting rod 23. At the warning water level 21, the Hall sensor 29 and the magnet 28 driven by the float 24 engage in non-contact operation, eliminating mechanical wear and corrosion issues. Combined with the stable sliding of the fixing rods 211 on both sides of the connecting rod 23 along the sliding groove 210 of the mounting housing 22, false triggering caused by water flow sloshing is significantly reduced. At the alert water level 25, the photoelectric level sensor 26 accurately detects high water levels and forms a high-low pairing with the warning water level 21, achieving dual protection of warning and response to avoid the risk of water overflow. The photoelectric level sensor 26, Hall sensor 29, and water pump 14 are linked to a controller. To ensure timely drainage when the water level exceeds the warning level and improve the reliability of monitoring and control, the combination of magnet 28 and Hall sensor 29 provides core support for early warning monitoring. Magnet 28 is made of high magnetic energy level neodymium iron boron material, which can stably output a strong magnetic field. Combined with the magnetic sensitivity of Hall sensor 29, it realizes non-contact sensing, fundamentally avoiding the contact problems caused by water stain corrosion and mechanical wear of traditional mechanical contact switches. In addition, magnet 28 is fixed in the mounting groove 27 of connecting rod 23. With the fixing rods 211 on both sides of connecting rod 23 sliding along the vertical guide groove 210 of mounting shell 22, it can effectively limit the lateral displacement of float 24, greatly reduce the false trigger rate of early warning caused by water flow sloshing, and significantly improve the reliability of monitoring and control.
[0018] Working principle: When the dehumidifier water level monitoring device is put into use, the condensate produced by the dehumidifier enters the inlet pipe 12 through the water receiving tray 13 and then flows into the dehumidifier water tank 11. When the water level in the dehumidifier water tank 11 rises, the float ball 24 drives the connecting rod 23 to slide upward along the sliding grooves 210 on both sides of the mounting shell 22. When the water level reaches the warning water level 21, the magnet 28 in the mounting groove 27 at the upper end of the connecting rod 23 and the Hall sensor 29 at the top of the mounting shell 22 are level with and close to the warning water level 21. The Hall sensor 29 sends a warning signal to the controller. If the water level continues to rise... As the water level rises to the warning level 25, the photoelectric liquid level sensor 26, located in the middle of the other side of the housing 22, detects the water level signal when it is level with the warning level 25 and transmits it to the controller. The controller then controls the water pump 14 at the bottom of one side of the dehumidifier water tank 11 to start, and discharges the condensate in the dehumidifier water tank 11 through the delivery pipe 15. When the water level drops, the float ball 24 drives the connecting rod 23 to fall back, the magnet 28 separates from the Hall sensor 29, the photoelectric liquid level sensor 26 is removed from the water level, and the controller controls the water pump 14 to stop running, thus realizing automatic monitoring of the water level and drainage control.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
