Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning drainage systems, and in particular to a water receiving tray structure, an air conditioner and an air-conditioning cleaning method. Background Art

[0002] With the widespread use of air conditioning equipment, the problem of dirty and clogged drainage systems has become increasingly prominent. During cooling, condensed water from the evaporator collects in the drain pan. Airborne dust particles carrying bacteria fall into the pan with the water droplets, multiplying in the moist environment to form bacterial clumps (sludge). Simultaneously, calcium and magnesium ions in the water precipitate, forming inorganic scale. The combined accumulation of these factors can clog the water pump intake, leading to water leakage in the indoor unit.

[0003] Existing solutions primarily rely on chemical descaling and disinfection agents, such as the periodic addition of peracetic acid or sodium hypochlorite. However, due to the continuous operation of the air conditioner, which generates new condensate, the active ingredients in the agent are diluted and lost within 6 to 8 weeks, necessitating frequent replenishment. Furthermore, the corrosive components in the agent can accelerate the risk of perforation of aluminum drain pans and copper piping, and disassembly and maintenance can damage delicate electronic components, significantly increasing maintenance costs for users.

[0004] To address these issues, existing technologies have proposed electrolyzed water sterilization. However, while this method uses electrode electrolysis to generate hydroxyl radicals to disinfect microorganisms, it still carries the risk of metal ion dissolution and electrode wear requiring replacement, essentially failing to avoid chemical intervention. Therefore, developing a physical anti-clogging solution that requires no reagents or downtime for maintenance is crucial for improving air conditioner reliability and user experience. Summary of the Invention

[0007] In a second aspect, the present invention provides an air conditioner comprising the water receiving tray structure as described above.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] The present invention aims to solve the problem of chemical interference in the sediment of the cleaning water receiving tray 10 of the air-conditioning equipment under the prior art. Figures 1 to 7The water receiving pan 10 structure is used to be installed in the indoor unit of the air conditioner. The water receiving pan 10 structure includes: a water receiving pan 10 for receiving condensed water; a drainage module 20, which is installed in the water receiving pan 10 and is used to drain the water in the water receiving pan 10; an electric field module 30, which includes a first polar body 31, a second polar body 32 and a power supply 33, wherein the first polar body 31 and the second polar body 32 are both electrically connected to the power supply 33, wherein the first polar body 31 and the second polar body 32 are arranged on the outer peripheral side of the drainage module 20, and the first polar body 31 and the second polar body 32 are isolated from each other. The water receiving pan 10 structure of the present invention is installed below the evaporator of the indoor unit of the air conditioner and is used to receive the condensed water generated during the refrigeration process. Specifically, the water receiving pan 10 is injection molded using engineering plastics and has good corrosion resistance. The water tray 10 is equipped with a drainage module 20, which includes a drainage channel and a drain outlet. Its primary function is to guide condensed water from the water tray 10 along a predetermined path to prevent leakage or accumulation due to excessive water levels. To further improve drainage efficiency and the system's anti-clogging effectiveness, the design of the drainage module 20 emphasizes a reasonable width and layout to ensure sufficient drainage speed. Specifically, the drainage module 20 is spaced a certain distance from the inner wall of the water tray 10. The electric field module 30 utilizes two electrodes: a first polar body 31 and a second polar body 32. These electrodes are connected to a power source 33 via wires 34 to form a stable electric field. Specifically, the first polar body 31 and the second polar body 32 are positioned opposite each other on the outer periphery of the drainage module 20 and are isolated from each other. Polar bodies are typically made of conductive metal and insulated to prevent short circuits or unnecessary leakage during operation, thereby ensuring safety and stability. With a certain distance between the two electrodes, the resulting electric field covers the entire area of the drainage module 20, effectively affecting ions and microorganisms in the water. The power supply 33 provides the necessary electrical energy to form a microcurrent between the electrodes, and the generated electric field can inhibit the deposition of scale and the reproduction of microorganisms. By arranging the two polar bodies opposite each other in the peripheral area of the drainage module 20, not only can the electric field be evenly distributed to cover the entire drainage area, but it can also ensure that both ions and microorganisms in the water flow have a better treatment effect. During installation, it should be ensured that the facing surfaces of the first polar body 31 and the second polar body 32 are as parallel as possible to maintain the stability and uniformity of the electric field. In addition, it is also necessary to ensure that the first polar body 31 and the second polar body 32 are at a sufficient distance from the drainage module 20 to ensure that the polar bodies do not affect the normal drainage.

[0031] In the technical solution of the present invention, two insulated positive and negative electrodes, namely a first polar body 31 and a second polar body 32, are provided on the outer periphery of the drainage module 20 mounted on the water receiving tray 10. These electrodes are connected to a power source 33 via wires 34 to create an electrostatic field coverage area. This electrostatic field effectively prevents the formation and adhesion of sediment in the drainage module 20 and its surrounding area, avoiding the problem of chemical interference.

[0032] The electric field between the two polar bodies of the present invention causes charged microorganisms, such as bacteria or algae, to migrate and aggregate toward the electrodes through the electrophoretic effect, while simultaneously inhibiting the activity of their cell division enzymes. The electric field also dissociates water molecules into single molecules and arranges them in an orderly manner, encapsulating ions such as calcium and magnesium ions, as well as anions such as CO₃₁⁻ and SO₃⁻⁻, preventing them from combining and forming scale. Furthermore, the polar bodies are shielded from condensed water and humid environments, eliminating electrolytic reactions and avoiding electrode corrosion associated with traditional electrolysis techniques.

[0033] In one embodiment, referring to Figure 1 and Figure 2 The water tray 10 has an inner bottom surface 11. The drainage module 20 includes a drain pump 21, which is mounted on the inner bottom surface 11. The first polar body 31 and the second polar body 32 are located around the drain pump 21. The bottom surface 11 is used to collect condensed water. The water tray 10 has an inner bottom surface 11, which serves as the primary collection area for condensed water. This ensures that condensed water generated during air conditioning operation is efficiently accumulated there, preventing dripping or accumulation. To enhance drainage capacity, the drainage module 20, which includes the drain pump 21, is installed on the inner bottom surface 11. The drain pump 21 is installed above the inner bottom surface 11 and in close contact with its surface, allowing condensed water to flow quickly into the drain pump 21 through gravity and the pumping action. The first polar body 31 and the second polar body 32 are located around the drain pump 21, surrounding it or arranged in its vicinity, forming an effective electric field, thereby ensuring good water flow and quality throughout the drainage area. Electrodes are arranged around the drainage pump 21 to exert the descaling and sterilizing effect of the electric field, thereby reducing the maintenance cycle of the drainage pump 21 and reducing the wear and tear caused by sediment inside the drainage pump 21, thereby extending its service life.

[0034] Further, refer to Figure 1 、 Figure 2 and Figure 6The drain pump 21 includes a water inlet 22, which is arranged near the bottom surface 11, and the first polar body 31 and the second polar body 32 are arranged near the water inlet 22. The drain pump 21 is equipped with a water inlet 22 and a water outlet 23. The water inlet 22 is close to the bottom surface 11 of the water receiving tray 10. With the help of gravity, condensed water can flow directly into the water inlet 22 of the drain pump 21, thereby ensuring the efficiency of drainage. The water outlet 23 is connected to a pipeline for discharging condensed water out of the water receiving tray 10. In order to maximize the effect of electronic descaling and sterilization, the first polar body 31 and the second polar body 32 are both arranged near the water inlet 22. When the condensed water flows from the water receiving tray 10 to the water inlet 22, the water flow first passes through the DC electric field area formed by the two plates. This layout helps the electric field cover the area where the water flows into the drain pump 21, achieving a more comprehensive inhibition of ions and microorganisms in the water.

[0035] Further, refer to Figure 2 、 Figure 6 and Figure 7 A support member 24 is provided between the drain pump 21 and the bottom surface 11. The support member 24 is hollow and has grating holes 25 spaced apart around the circumference of the support member 24 near the bottom surface 11. The water inlet 22 is provided in the support member 24. To ensure the stability and reliability of the drain pump 21, a dedicated support member 24 is provided between the drain pump 21 and the water receiving tray 10. The support member 24 adopts a hollow design structure and is provided with a plurality of grating holes 25 spaced apart around the circumference of the support member 24. The grating holes 25 allow condensed water to pass through, ensuring that water flows smoothly into the water inlet 22 of the drain pump 21 set in the support member 24. At the same time, the grating holes 25 can also block larger impurities from entering the pump cavity, reducing scale nucleation materials, preventing blockage, and ensuring the normal operation of the drainage system. In addition, a circular pit 13 is provided on the bottom surface 11. The support member 24 is provided in the pit 13, and the grating holes 25 are provided near the bottom of the pit 13. The pit 13 allows the remaining water on the bottom surface 11 to be further gathered together, so that the remaining condensed water in the water receiving tray 10 that cannot be discharged after the air conditioner stops running is all within the range of the electric field.

[0036] In one embodiment, a flow channel 12 is further provided on the bottom surface 11 of the water receiving tray 10, and the first polar body 31 and the second polar body 32 are arranged near the flow channel 12, and the flow channel 12 is used to gather the condensed water to the drain pump 21. The bottom surface 11 of the water receiving tray 10 is provided with a special flow channel 12 to guide and gather the condensed water to ensure that it can flow efficiently to the drain pump 21. The flow channel 12 is arranged obliquely along the bottom area of the water receiving tray 10, and is inclined from the far end to the direction close to the drain pump 21, ensuring that there is an appropriate slope and path design to utilize the effect of gravity. Specifically, the flow channel 12 is integrally generated when the water receiving tray 10 is molded, so the connection between each flow channel 12 is smooth, and there is no structure that may hinder the flow of condensed water. The electric field formed by the two polar bodies spans the area from the flow channel 12 to the water inlet 22, so that when the condensate accumulates around the water inlet 22, it can be affected by the electric field, thereby increasing the range of action of the electric field.

[0037] Further, refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 7 , the flow channel 12 is inclined along the side away from the drain pump 21 to the side close to the drain pump 21. The flow channel 12 is inclined along the side away from the drain pump 21 to the other side close to the drain pump 21, specifically, the flow channel 12 is gradually inclined from the higher end at the far end and the side close to the drain pump 21 to a lower position. This structural arrangement is intended to make full use of the natural gravity to guide the condensed water to flow quickly and smoothly along the flow channel 12 to the water inlet 22 of the drain pump 21, thereby improving the drainage efficiency. Specifically, the inclination of the flow channel 12 also adopts a slope gradient design, starting from 2.5° at the farthest distance from the drain pump 21, and linearly increasing to 5° toward the drain pump 21 to form an accelerated drainage channel.

[0038] In one embodiment, the surfaces of the first polar body 31 and the second polar body 32 are wrapped with an insulating material (not shown in the figure). The surfaces of the first polar body 31 and the second polar body 32 are wrapped with insulating material to physically isolate the electrochemical reaction between the electrodes and the water body. Specifically, the surface of the polar body is evenly coated with polytetrafluoroethylene (PTFE) as a base layer, and then the outer layer is hot-pressed and coated with a modified polypropylene (PP) insulating shell to achieve complete wrapping of the polar body. In addition, the terminal connecting the polar body to the wire 34 is also encapsulated with a two-component epoxy resin to form a fully sealed waterproof structure, thereby ensuring sufficient waterproofness.

[0039] The present invention also discloses an air conditioner utilizing the water tray 10 structure described in the above embodiments. During operation, condensed water is collected and directed by the water tray 10, ultimately draining rapidly from the system through the action of an electric field and the cooperation of a drain pump 21. This significantly improves drainage efficiency and system stability. This not only enhances the durability of the air conditioner and reduces maintenance costs, but also ensures the safety and cleanliness of the system during long-term operation. The overall design meets environmental and energy-saving requirements, fully demonstrating the technical advantages and practical application value of the present invention.

[0040] In order to further illustrate that the air conditioner using the water receiving tray 10 structure of the present invention has better performance than existing air conditioners on the market, a descaling test conducted on the air conditioner of the present invention is listed below.

[0041] The experimental plan is:

[0042] (1) Preparation of a scaling solution with a hardness of 400 mg / L: Dissolve 0.44 g of CaCl2 in 500 mL of distilled water and 0.67 g of NaHCO3 in another 500 mL of distilled water, then slowly mix the two solutions. This scaling solution not only simulates scaling under actual water conditions, but is also easy to operate and low-cost, making it suitable for large-scale scaling tests.

[0043] (2) Take four 50mm*100mm aluminum sheets, ultrasonically clean them with anhydrous ethanol for 10 minutes to remove surface attachments, then dry them at 80℃ for 30 minutes and weigh and record them. Take two sheets from each and place them in two 500mL beakers in an alternating manner so that each sample can be evenly exposed to the scaling liquid.

[0044] (3) One set of solutions was placed in a 5V regulated electric field. The positive electrode was inserted into the solution using an electrode rod, and the negative electrode was connected to a copper sheet clamped to the edge of the beaker. The test temperature was 80°C. After scaling for 4 hours, each test piece was removed and dried at 80°C for 30 minutes and weighed.

[0045] After 4 hours of the experiment, each test piece was taken out and dried at 80℃ for 30 minutes and weighed. When there was no electric field in the solution, there was a lot of white scale on the surface, but after the solution was connected to a 5V, 69.3mA electric field, there was no obvious scale layer on the surface of the test piece.

[0046] After the test, the average amount of scaling on the surface of the two groups of test pieces is as follows: Figure 12 As shown, the amount of scaling per unit area (cm2) on the inner surface of the test piece is reduced by about 73% under the influence of the electric field, and the scaling inhibition effect is quite obvious.

[0047] The present invention also provides an air conditioner cleaning method, which is applied to the air conditioner in the above embodiment. Figure 8 , the method comprising:

[0048] S110, obtaining the condensed water accumulation state in the water receiving tray;

[0049] S120, when condensed water accumulates in the water receiving tray, starting the drainage module and the electric field module;

[0050] S130, when the condensed water in the water receiving tray is drained, the drainage module is closed, and the electric field module is kept running for a preset time and then closed.

[0051] To implement this air conditioner cleaning method, the accumulation of condensed water in the water tray 10 is first monitored in real time during system operation using a sensor or monitoring device. Specifically, a water level sensor is used to monitor the accumulation of condensed water. This water level sensor shares the power supply 33 circuit with the electric field module 30, enabling the shortest control circuit and reducing wiring within the air conditioner. This detection can be accomplished by monitoring the water level or the flow rate in and out of the water tray 10. When the monitoring system detects the presence of accumulated condensed water in the water tray 10, the next step is to activate the drainage module 20 and the electric field module 30. Specifically, when the water level exceeds a predetermined value, the system is deemed to be in an "accumulation state." At this point, the drain pump 21 in the drainage module 20 begins operating, draining the condensed water out of the system through a connected drain pipe, ensuring the water level in the water tray 10 is lowered to prevent overflow and scaling. Simultaneously, the electric field module 30 is activated, generating a high-frequency electric field that acts on the condensed water, inhibiting scale formation and microbial growth, thereby removing scale, sterilizing, and preventing blockage. Specifically, the power supply 33 applies a DC voltage of 15 to 50 V to the bipolar body. In addition, the drain pump 21 is delayed for a certain period of time after the electric field module 30 is started to ensure that the water discharged by the drain pump 21 is first affected by the electric field.

[0052] When the monitoring system detects that the condensate has been effectively drained—that is, the water level in the water tray 10 has dropped to its lowest level or reached a set threshold—it immediately shuts off the drain pump 21 in the drainage module 20, halting the condensate discharge. After drainage ceases, to ensure continued water cleanliness, the electric field module 30 continues operating for a preset period. This period primarily utilizes the sterilizing and scale-inhibiting effects of the electric field to comprehensively treat any remaining microorganisms and particles in the water, preventing scale redeposition and microbial regeneration. After the predetermined time, the electric field module 30 is shut off, completing the maintenance and cleaning process.

[0053] The advantage of the method of this embodiment is that it effectively combines mechanical drainage and electronic descaling and sterilization technology through intelligent detection and automatic adjustment of drainage and start / stop of the electric field, significantly improving the continuous cleaning ability of the air-conditioning system, extending the service life of the equipment, and reducing the frequency of maintenance.

[0054] Further, refer to Figure 9, the method further comprises:

[0055] S121, obtaining the condensed water flow rate flowing through the drainage module;

[0056] S122. Control the output power of the power supply to the first polar body and the second polar body according to the condensed water flow rate.

[0057] By installing a flow sensor or flow monitoring device in the drainage pipeline, the condensate flow rate through the drainage module 20 is monitored in real time. When the condensate flow rate reaches a preset threshold or changes significantly, the control system adjusts the output power of the power supply 33 based on the specific flow data to optimize the effect of the electric field.

[0058] When the flow rate is high, indicating sufficient condensate flow, the electric field's sterilization and scale inhibition effects can be enhanced. At this time, the control system will provide a higher power output to the first polar body 31 and the second polar body 32 to generate a stronger electric field effect, thereby more effectively inhibiting scale deposition and microbial growth. Conversely, when the flow rate is low, meaning that the condensate flow is reduced, the effect of the electric field can be weakened accordingly, thereby reducing energy consumption and extending the service life of the equipment. In the control strategy, digital algorithms or fuzzy control logic are used to convert the flow signal into corresponding power adjustment parameters, achieving precise control of the output of power supply 33.

[0059] The method of this embodiment ensures the dynamic adaptation of the electric field effect, improves the intelligence level and energy-saving effect of the system, and also ensures the continuous suppression of scale and microorganisms, and can achieve the best descaling and sterilization effect under different condensate flow conditions.
