Description

Technical Field

[0001] This utility model belongs to the field of air conditioner water leakage monitoring technology, and in particular relates to an air conditioner equipment water leakage monitoring device. Background Technology

[0002] When an air conditioner is running, if the condensate drain pipe is blocked by dust, mold, or foreign objects, the condensate cannot be discharged normally. As the condensate produced on the evaporator surface continues to accumulate and exceeds the capacity of the drip tray, it will overflow from the bottom of the indoor unit, causing water leakage. This may not only damage the walls and floors, but may also cause electrical safety hazards.

[0003] Most ordinary air conditioning units on the market lack the design of active leak detection function, which makes it difficult to detect and actively deal with problems in the condensate drainage system in a timely manner. When the drain pipe is blocked by dust, mold, or foreign objects, the condensate cannot be discharged normally and will gradually accumulate in the drip tray. Since there is no water level monitoring device installed, the water will only drip from the bottom of the indoor unit when the drip tray is completely full and overflows. By this time, the leak has often been going on for some time. This passive detection method has obvious lag and may not only cause property damage such as wet walls and waterlogged floors, but may also cause safety hazards due to water seeping into the electrical system.

[0004] Even more seriously, in unattended situations (such as at night or after office hours), leaks may go unnoticed for a long time, leading to further damage. Utility Model Content

[0005] The purpose of this invention is to overcome the defects of the prior art and provide a water leakage monitoring device for air conditioning equipment. By forming a conductive circuit between a metal probe installed in the water receiving pan and a first alarm, an alarm is immediately triggered when condensate accumulates to the contact probe, thereby realizing real-time monitoring of water leakage and timely reminding the user before condensate overflows.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] An air conditioning equipment leakage detection device includes a water receiving tray, one end of which is provided with a water outlet pipe and a drain pipe connected to the water outlet pipe. At least two metal probes are provided on the inner wall of one side of the water receiving tray. The metal probes penetrate the water receiving tray. Each metal probe is connected to a lead wire at the end away from the inner wall of the water receiving tray. The lead wire extends to the outside of the water receiving tray and is connected to a first alarm.

[0008] This implementation method forms a conductive circuit between a metal probe installed in the water collection pan and a first alarm. When condensate accumulates to the contact probe, the alarm is triggered immediately, enabling real-time monitoring of water leakage. This alerts the user before condensate overflows, effectively solving the drawbacks of passive water leakage in traditional air conditioners. It transforms post-event handling into pre-event prevention, reducing the risk of water leakage caused by poor drainage.

[0009] In one embodiment, a through mounting groove is provided on the inner wall of one side of the water receiving tray, the metal probe is disposed in the mounting groove, and a sealing plug is provided in the gap between the metal probe and the mounting groove.

[0010] In this embodiment, the metal probe is sealed by a sealing plug and detachably installed in the mounting groove. The cooperation between the sealing plug and the mounting groove facilitates the installation and removal of the metal probe on the water receiving tray, thereby facilitating production assembly.

[0011] In one embodiment, a mounting base for installing the first alarm is provided on one side of the water receiving tray, and the mounting base is provided with a mounting slot.

[0012] Through this embodiment, the first alarm can be quickly installed and removed from the outside of the water receiving tray by the cooperation of the mounting base and the mounting slot, which facilitates maintenance and replacement.

[0013] In one embodiment, a protective cover is also provided on one side of the water receiving tray, and the protective cover covers the outside of the lead wire and the first alarm.

[0014] This embodiment improves the protection of first alarm devices and the like by providing a protective cover, reducing damage during installation and maintenance.

[0015] In one embodiment, a locking flange is provided on one side of the water receiving tray, the locking flange is provided on the upper and lower sides of the first alarm, and the protective cover has a locking edge corresponding to the locking flange;

[0016] Through this embodiment, the engagement of the engagement edge and the engagement flange enables the rapid installation and convenient disassembly of the protective cover.

[0017] In one embodiment, a liquid level detector is also provided on the water receiving tray;

[0018] This implementation method assists in detecting liquid levels, avoids the failure of metal probes, and improves the accuracy of leak detection in air conditioning equipment.

[0019] In one embodiment, the water outlet pipe is provided with a valve and an air inlet pipe. The air inlet pipe is located at one end near the drain pipe and between the valve and the drain pipe. The air inlet pipe is connected to an air supply assembly.

[0020] In this embodiment, the air supply component is used to output high-pressure airflow through the air inlet pipe to impact the drain pipe, thereby solving the water leakage problem caused by the blockage of the drain pipe.

[0021] In one embodiment, a pressure detector is also installed on the water outlet pipe, and a second alarm that is electrically connected to the pressure detector is also installed on the side wall of the water receiving tray at one end of the water outlet pipe.

[0022] In this embodiment, when high-pressure airflow is input into the drain pipe through the air inlet pipe, the air pressure in the outlet pipe and the drain pipe can be detected by a pressure detector. If water leakage is caused by a blockage in the drain pipe, the air pressure will rise; otherwise, the air pressure will not change. This can rule out the possibility of water leakage in the air conditioning equipment caused by a blockage in the drain pipe, and detect other situations.

[0023] In one embodiment, the air supply assembly includes an air pump and an air delivery hose disposed at the output end of the air pump, the tail end of the air delivery hose being connected to the air inlet pipe.

[0024] In this embodiment, the air pump delivers airflow through the air delivery hose to the air inlet pipe and then into the water outlet pipe. At this time, the valve is closed in advance, closing the channel of the water outlet pipe toward the water tray. This ensures that the airflow can only flow toward the drain pipe. If the air conditioning equipment leaks due to blockage of the drain pipe, the impact of the airflow can open the blockage, allowing the water in the drain pipe to be discharged in time, thus achieving automatic cleaning.

[0025] In one embodiment, two symmetrical metal probes are provided on the inner wall of one side of the water receiving tray.

[0026] The beneficial effects of this utility model are as follows:

[0027] (1) To achieve dual protection of active monitoring and automatic cleaning, this utility model forms a conductive circuit with the first alarm by symmetrically arranged metal probes in the water receiving pan. When the condensate accumulates to the contact probe, the alarm is triggered immediately, realizing real-time monitoring of water leakage. After detecting abnormal water level, the drain pipe is judged to be blocked according to the detection data of the pressure detector. If the drain pipe is blocked, the high-pressure air pump is automatically started to impact and clean the blocked drain pipe, effectively solving the drawbacks of passive water leakage of traditional air conditioners, turning post-event handling into pre-event prevention, and reducing the risk of water leakage caused by poor drainage.

[0028] (2) The dual-redundant monitoring scheme combines the conductive detection of metal probes and the capacitive liquid level sensor. When the metal probe fails due to scale, the liquid level detector can still work normally. Attached Figure Description

Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings.

[0040] This utility model provides a water leakage monitoring device for air conditioning equipment, such as Figures 1 to 6As shown, it includes a water receiving tray 1. Two sets of metal probes 2 are symmetrically arranged on the inner wall of the water receiving tray 1. Lead wires 3 are connected to the outer side of the metal probes 2. The two sets of lead wires 3 extend outward to the outer side of the water receiving tray 1 and are connected to a first alarm 4. The first alarm 4 is detachably fixed to the outer side of the water receiving tray 1. A water outlet pipe 5 is provided at one end of the water receiving tray 1. A drain pipe 6 is connected to the water outlet pipe 5. A valve 7 is provided on the water outlet pipe 5. An air inlet pipe 8 is connected to the water outlet pipe 5 outside the valve 7. An air supply component is connected to the input end of the air inlet pipe 8.

[0041] It should be noted that in this embodiment, active monitoring and automatic cleaning are achieved simultaneously. By forming a conductive circuit with the first alarm 4 through two metal probes 2 symmetrically arranged in the water receiving pan 1, an alarm is immediately triggered when condensate accumulates to the point of contact with the metal probes 2, realizing real-time monitoring of water leakage. After detecting abnormal water level, the detection data of the pressure detector 17 is used to determine whether the drain pipe 6 is blocked. If the drain pipe 6 is blocked, the high-pressure air pump 19 is automatically started to impact and clean the blocked drain pipe 6. This effectively solves the drawbacks of passive water leakage in traditional air conditioners, transforming post-event handling into pre-event prevention and reducing the risk of water leakage caused by poor drainage.

[0042] In one embodiment, such as Figure 4 As shown, an installation groove 9 is provided on the side wall of the water receiving tray 1, and a sealing plug 10 is provided on the outside of the metal probe 2. The metal probe 2 is sealed by the sealing plug 10 and is detachably installed in the installation groove 9. The cooperation between the sealing plug 10 and the installation groove 9 facilitates the installation and removal of the metal probe 2 on the water receiving tray 1, thereby facilitating production and assembly.

[0043] In one embodiment, such as Figure 5 As shown, a mounting base 11 is provided on the outer side of the water receiving tray 1, and a mounting slot 12 is provided on the mounting base 11. The first alarm 4 is locked and fixed on the mounting base 11. Through the cooperation of the mounting base 11 and the mounting slot 12, the first alarm 4 can be quickly installed and removed on the outer side of the water receiving tray 1, which is convenient for maintenance and replacement.

[0044] In one embodiment, such as Figure 2 and Figure 5 As shown, a protective cover 13 is provided on the outer side of the water receiving tray 1. The protective cover 13 is sleeved on the outer side of the lead wire 3 and the first alarm 4. A locking edge 14 is provided on the inner side of the protective cover 13, and a locking flange 15 is provided on the outer side of the water receiving tray 1. The locking edge 14 and the locking flange 15 mutually limit and lock each other. The protective cover 13 can improve the protection of the first alarm 4 and reduce the damage during installation and maintenance. The cooperation between the locking edge and the locking flange 15 can realize the quick installation and convenient disassembly of the protective cover 13.

[0045] In one embodiment, such as Figure 3As shown, a liquid level detector 16 is installed on the water receiving tray 1. The liquid level detector 16 is preferably a capacitive liquid level sensor. If the water receiving tray 1 is made of non-metallic material, the capacitive liquid level sensor can be directly installed on the outside of the water receiving tray 1. If the water receiving tray 1 is made of metallic material, the electrode patch of the capacitive liquid level sensor needs to be installed on the inside of the water receiving tray 1. This can help detect the liquid level, avoid the failure of the metal probe 2, and improve the accuracy of water leakage detection of air conditioning equipment. When the liquid level detector 16 and the metal probe 2 are triggered simultaneously or any one of them triggers the monitoring conditions, the above monitoring, alarm and cleaning process can be run.

[0046] In one embodiment, such as Figure 6 As shown, a pressure detector 17 is installed on the water outlet pipe 5. When high-pressure airflow is input into the drain pipe 6 through the air inlet pipe 8, the pressure detector 17 can detect the air pressure in the water outlet pipe 5 and the drain pipe 6. If the water leakage is caused by the blockage of the drain pipe 6, the air pressure will rise. If not, the air pressure will not change. This can rule out the possibility of water leakage caused by the blockage of the drain pipe 6, and detect other situations.

[0047] Furthermore, the pressure detector 17 is also electrically connected to a second alarm 18. The second alarm 18 can be installed on the outer wall of the drip tray 1 in the same manner as the first alarm 4, or it can be installed in other suitable locations on the indoor unit of the air conditioner. During the process of impacting the drain pipe 6 with high-pressure airflow, if the air conditioner leaks water due to blockage of the drain pipe 6, the pressure detector 17 will not rise when the high-pressure airflow clears the blockage and discharges the impurities from the drain pipe 6, so the second alarm 18 will not sound. However, when the air conditioner leaks water due to blockage of the drain pipe 6, but the high-pressure airflow cannot automatically clear the blockage, the pressure detector 17 will rise. When it rises to a certain value, the second alarm 18 will sound an alarm, thereby reminding relevant personnel to manually clear the blockage and prevent water from overflowing from the drip tray 1, which could lead to water leakage.

[0048] In one embodiment, such as Figure 1 and Figure 6As shown, the air supply component includes an air pump 19, which is a miniature high-pressure air pump, such as a THD miniature high-pressure air pump. The output end of the air pump 19 is equipped with an air delivery hose 20, and the tail end of the air delivery hose 20 is connected to the air inlet pipe 8. When the air pump 19 is started, the airflow is delivered to the air inlet pipe 8 through the air delivery hose 20 and enters the water outlet pipe 5 through the air inlet pipe 8. At this time, the control valve 7 is closed in advance, so that the channel of the water outlet pipe 5 towards the water receiving tray 1 is closed, so that the airflow can only flow towards the drain pipe 6. If the air conditioning equipment leaks water due to the blockage of the drain pipe 6 by impurities, the impact of the airflow can open the blockage, so that the water in the drain pipe 6 can be discharged in time, realizing automatic cleaning.

[0049] In one embodiment, the working principle of this utility model is as follows:

[0050] When the drain pipe 6 is blocked, condensate will accumulate in the drip tray 1. When the water level in the drip tray 1 exceeds or touches the position of the metal probe 2, the conductivity of the water will create a conductive circuit between the two sets of metal probes 2 and the first alarm 4, causing the first alarm 4 to sound an alarm and remind relevant personnel to check. At the same time, when the first alarm 4 sounds an alarm, the control valve 7 is closed. The valve 7 is preferably a solenoid valve, and the air pump 19 is started simultaneously. Under the action of the air pump 19, the airflow is delivered to the air inlet pipe 8 through the air delivery hose 20 and enters the water outlet pipe 5 through the air inlet pipe 8. At this time, the control valve 7 is closed in advance, so that the channel of the water outlet pipe 5 towards the drip tray 1 is closed, so that the airflow can only flow towards the drain pipe 6. If the air conditioning equipment leaks water due to the blockage of the drain pipe 6, the impact of the airflow can open the blockage, so that the water in the drain pipe 6 can be discharged in time, realizing automatic cleaning.

[0051] Furthermore, the air pressure inside the water pipe 5 is detected by the pressure detector 17. If the leak is caused by the blockage of the drain pipe 6, the air pressure will rise briefly and return to normal after the blockage is cleared. Otherwise, the air pressure will not change, thus ruling out the possibility that the air conditioning equipment is leaking due to the blockage of the drain pipe 6, and other situations can be detected.

[0052] In the process of impacting the drain pipe 6 with high-pressure airflow, if the air conditioning equipment leaks due to blockage of the drain pipe 6, the pressure detector 17 will not rise to the set value when the high-pressure airflow clears the blockage and discharges the impurities from the drain pipe 6, so the second alarm 18 will not sound. However, when the air conditioning equipment leaks due to blockage of the drain pipe 6, but the high-pressure airflow cannot automatically clear the blockage, the air pressure in the outlet pipe 5 and the drain pipe 6 will increase, and the pressure detector 17 will detect the value. When it rises to a certain value, the second alarm 18 will sound an alarm to remind relevant personnel to manually clear the blockage and prevent the water in the drip tray 1 from overflowing and causing the equipment to leak. At this time, when the set air pressure reaches a certain value, the operation of the air pump 19 will be automatically stopped to prevent the drain pipe 6 from rupturing due to excessive air pressure.

[0053] In one embodiment, the operation of the air pump, valves and other related electrical components in the above-mentioned operation process can be controlled by the controller built into the air conditioner.
