Description

Technical Field

[0001] This invention relates to the field of marine air conditioning technology, and more specifically, to an air conditioning condensate re-isolation system and a floor-standing air conditioner using the same. Background Technology

[0002] The defects in the installation process and the limitations of materials in traditional floor-standing air conditioners result in a "cold bridge" phenomenon in the frame structure, which affects the heat insulation effect and causes energy loss. It also causes condensation in the air conditioner, and long-term condensation can penetrate into the interior of the air conditioner and cause corrosion.

[0003] Meanwhile, existing floor-standing air conditioners all generate condensate during operation from their internal cooling components, humidifiers, air guides, and fan impellers. The traditional method for collecting this condensate and the aforementioned condensation is to simply install a drip tray under these components, collecting the condensate and draining it directly through a single pipe.

[0004] However, during the long-term collection of condensate in the drip tray, various impurities from the air, such as dust, microorganisms, and other tiny particles, inevitably mix in. These impurities enter the drip tray along with the condensate and remain there for an extended period. Because the environment inside the drip tray is relatively enclosed and humid, it is highly suitable for the growth and reproduction of bacteria and mold, leading to the proliferation of a large number of microorganisms. These microorganisms secrete a sticky substance during their growth. When this substance mixes with dust, it forms what is known as "biological slime." This slime has strong adhesive properties and easily adheres to the inner wall of the drain pipe, gradually accumulating and eventually causing a blockage. Once the drain pipe is blocked, the condensate cannot drain properly and overflows from the drip tray, eventually seeping into the electrical components inside the air conditioner. Over time, these microorganisms not only produce unpleasant odors but also pollute the air flowing through the drip tray, affecting indoor air quality. Therefore, a blocked drip tray not only damages the air conditioner's electrical system but can also cause further pollution and damage to the indoor environment. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an air conditioning condensate re-isolation system and a floor-standing air conditioner using the same, which solves the problem that the drain pipe is easily blocked when the drip tray is dirty.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides an air conditioning condensate re-isolation system, including a water receiving assembly. The water receiving assembly includes a water receiving tray for collecting condensate, and further includes: a flushing unit disposed above or inside the water receiving tray for flushing the inner wall of the water receiving tray; and a condensate treatment unit connected to the drain pipe of the water receiving tray, the condensate treatment unit being used for recycling and discharging condensate. During normal operation, the condensate treatment unit recycles the condensate; when the flushing unit is operating, the condensate treatment unit discharges the condensate. The condensate treatment unit includes a recovery pipe and a drain pipe connected to the drain pipe via a pipeline, both the recovery pipe and the drain pipe being equipped with solenoid valves, and the recovery pipe having a filter.

[0008] According to one embodiment of the present invention, the water receiving tray is provided with a drain trough corresponding to the centrifugal fan and a sink trough corresponding to the cooling coil and the humidifier, respectively. The drain trough introduces condensate into the sink trough through a slope. The drain pipe is connected to the bottom of the sink trough. The inner walls of the sink trough and the drain trough on both sides are smooth slopes or arc surfaces.

[0009] According to one embodiment of the present invention, one end of the recovery pipe is connected to the input end of the filter via a diversion tee pipe, the other end of the diversion tee pipe is connected to the drain pipe, the output end of the filter is connected to a reprocessing pipe and a backflushing pipe for rinsing the filter, and solenoid valves are provided on the reprocessing pipe, the backflushing pipe and the pipes connecting the diversion tee pipe and the drain pipe.

[0010] According to one embodiment of the present invention, the flushing unit includes a common pipe disposed on both sides of the outer wall of the sinking tank, the common pipe being provided with a plurality of flushing nozzles pointing towards the inner wall of the sinking tank, the common pipe being connected to an external water source through a water inlet pipe, and the water inlet pipe being provided with a regulating valve.

[0011] According to one embodiment of the present invention, a drying unit is further included. The drying unit includes a blower, an air collecting hood, and a hot air pipe arranged along the inner contour of the water receiving tray. The air collecting hood is located behind the heating coil and its opening faces the heating coil. The input end of the blower is connected to the air collecting hood through a suction pipe, and its output end is connected to one end of the hot air pipe through the air supply pipe. The hot air pipe is provided with multiple air outlets, and the air outlets point to the sink or drainage trough.

[0012] According to one embodiment of the present invention, a control unit is further included. The control unit is electrically connected to the rinsing unit, the condensate treatment unit, and the drying unit, and performs the following specific mechanisms: when the air conditioner is working, the condensate treatment unit is activated to recycle the condensate; when the air conditioner is stopped, the rinsing unit is activated to rinse the sink, and the condensate treatment unit is activated simultaneously to discharge the cleaning fluid; and after the air conditioner is stopped or rinsing is completed, the drying unit is activated to dry the drain pan.

[0013] According to one embodiment of the present invention, the reprocessing tube is provided with a turbidity sensor that is signal-connected to the control unit, and the control unit controls the operation of the rinsing unit according to the signal of the turbidity sensor.

[0014] According to one embodiment of the present invention, the opening of the air collecting hood is provided with a mesh cover.

[0015] The present invention also provides a floor-standing air conditioner, including an air conditioning unit, wherein the water receiving component is installed in the bottom area of ​​the air conditioning unit, and the water receiving tray is disposed below the cooling coil, humidifier, air guide shroud and centrifugal fan inside the air conditioning unit.

[0016] According to one embodiment of the present invention, the frame of the air conditioning unit includes a three-way connector and a column connected thereto. The column is formed by slidingly engaging an L-shaped plate, a first decorative plate, a second decorative plate, and a connecting strip through a slot and plug structure. The L-shaped plate and the connecting strip are made of aluminum profiles, and the first and second decorative plates are made of PVC material. The internal cavity of the column is filled with a foaming agent.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. In this invention, the frame structure of the air conditioning unit is improved by using high-strength and corrosion-resistant aluminum profiles as the outer surface of the frame and a decorative panel with low thermal conductivity as the inner surface of the frame. Furthermore, a foaming agent is filled into the inner cavity of the frame to improve the heat insulation effect. This effectively blocks the heat conduction of the frame to the cold source, avoids condensation on the outer wall, and reduces the air leakage rate, thereby improving the overall energy efficiency of the air conditioning unit.

[0019] 2. In this invention, when the water tray becomes dirty, the rinsing unit can automatically rinse the inner wall of the water tray; and a condensate treatment unit is also provided on the drain pipe of the water tray. This condensate treatment unit recycles and treats the condensate generated by the air conditioning unit normally. It works in conjunction with the rinsing unit to discharge the wastewater generated by the cleaning unit during operation, thereby effectively removing the biological slime on the inner wall of the water tray, significantly reducing the risk of drainage blockage, and reducing odor generation.

[0020] 3. In this invention, a drying unit is set inside the water receiving pan. The drying unit forces the hot air generated by the heating coil into the surface of the water receiving pan, and dries the surface of the water receiving pan when the air conditioner is turned off, thereby inhibiting the growth of microorganisms. In addition, the drying unit and the drainage groove opened on the surface of the water receiving pan can also assist in drainage and prevent condensate from accumulating on the surface of the water receiving pan.

Detailed Implementation

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] During the operation of air conditioning unit 1, the cooling coil 4, acting as the evaporator, generates a large amount of condensate on its surface due to the cooling effect. The humidifier 5 produces overflow water during humidification, requiring collection and treatment of this condensate and overflow. Furthermore, when encountering low-temperature, high-humidity air, the metal surfaces of the air guide shroud 6 and centrifugal fan 7 may also generate condensate because their temperature is below the dew point of the air. To effectively address these issues, this invention provides an air conditioning condensate re-isolation system. This system can collect and treat the condensate generated by these components in a unified manner, separating condensate from wastewater, reducing the risk of drainage blockage, and minimizing odor generation.

[0033] Example 1, see Figures 1 to 3 In this embodiment 1, the frame 9 of the air conditioning unit 1 was also improved to reduce the air leakage rate and improve the overall heat insulation performance, thereby preventing energy loss and condensation on the outer shell.

[0034] Furthermore, the frame 9 in this embodiment is assembled from multiple tee connectors 901 and connected uprights 902. Each upright 902 is not a single piece of material, but rather composed of four components, including an L-shaped plate 9021 (as the main load-bearing structure), a first decorative plate 9022, a second decorative plate 9023, and a connecting strip 9024. The tee connectors 901 have three inserts 9011 that plug into the uprights 902. The L-shaped plate 9021 and the connecting strip 9024 are made of high-strength, corrosion-resistant aluminum profiles; while the first decorative plate 9022 and the second decorative plate 9023 are made of PVC material with low thermal conductivity. These four components are laterally slidably engaged through slots and inserts, ultimately forming a closed hollow cross-section. After assembly, a foaming agent, such as polyurethane foam, is injected into this hollow cross-section to form a highly efficient thermal insulation core layer.

[0035] It should be noted that, in this configuration, the L-shaped panel 9021 is exposed on the outside of the frame 9 to ensure the structural strength of the frame 9; while the first decorative panel 9022 and the second decorative panel 9023 are concealed inside the frame 9. The portions of these panels that directly contact the cold source use non-metallic materials with good thermal insulation properties. The connecting strip 9024 is also located inside the frame 9 to ensure the connection strength between the first decorative panel 9022 and the second decorative panel 9023. In this embodiment, the inner cavity of the frame 9 is filled with a foaming agent, effectively blocking the heat conduction path. This effectively solves the "cold bridge" problem present in traditional all-metal frames, reduces air leakage, minimizes heat loss, and prevents condensation on the unit casing in low-temperature and high-humidity environments, further improving the energy efficiency and operational stability of the air conditioner. Next, refer to... Figures 1 to 6 This embodiment provides an air conditioning condensate re-isolation system. The system includes a water collection assembly 8 for unified collection and treatment of condensate. Specifically, the water collection assembly 8 mainly consists of a water collection tray 801, a condensate treatment unit 802, and a rinsing unit 804. The water collection tray 801 has a recessed trough 8011 and a drain trough 8012 arranged side-by-side. Since the cooling coil 4 and humidifier 5 produce more condensate than the air guide shroud 6 and centrifugal fan 7, the recessed trough 8011 is specifically positioned to correspond to the cooling coil 4 and humidifier 5, while the drain trough 8012 is positioned to correspond to the centrifugal fan 7. Furthermore, the groove of the drain trough 8012 features a slope design, allowing condensate on the surface of the water collection tray 801 to flow into the recessed trough 8011 via the slope. In addition, the inner walls on both sides of the sink 8011 and the drain 8012 are provided with smooth slopes or arcs to facilitate the flow of condensate to the bottom of the sink 8011. The bottom of the sink 8011 is connected to the drain pipe 8013 to facilitate the discharge of condensate.

[0036] See Figure 4 and Figure 7In this embodiment, a flushing unit 804 is provided. The flushing unit 804 includes a common pipe 8042 disposed on both sides of the outer wall of the settling tank 8011. Multiple flushing nozzles 8044, pointing towards the inclined inner wall of the settling tank 8011, are evenly installed on the common pipe 8042. One end of the common pipe 8042 is connected to an external water source through a water inlet pipe 8041. A regulating valve 8043 is also installed on the water inlet pipe 8041 to control the flushing water pressure and its on / off state. When dirt appears on the inner wall of the settling tank 8011, the flushing unit 804 needs to be activated to flush it. During the flushing process, the flushing unit 804 applies a jet of water at 0.3 to 0.5 MPa, which can effectively remove biological slime from the inner wall of the water receiving tray 801, significantly improving efficiency compared to traditional manual cleaning.

[0037] Next, since air conditioning unit 1 produces condensate during normal operation, and this condensate and condensation water collects dust and forms biofilm on the equipment, the flushing unit 804 needs to be activated to flush it. (See reference...) Figures 4 to 6 In this embodiment, a condensate treatment unit 802 is also provided on the drain pipe 8013 of the water receiving pan 801. This condensate treatment unit 802 recovers and treats the condensate generated normally by the air conditioning unit 1. It cooperates with the flushing unit 804 and is connected to the drain pipe 8013 to discharge the wastewater generated during the operation of the cleaning unit. The condensate treatment unit 802 is used to separate condensate and wastewater. Specifically, the condensate treatment unit 802 includes a recovery pipe 8022 and a drain pipe. A first valve body 80221 and a second valve body 80231 are respectively installed on the recovery pipe 8022 and the drain pipe. A filter 8026 is connected in series on the recovery pipe 8022 to purify the condensate. One end of the recovery pipe 8022 is connected to the input end of the filter 8026 through a diversion tee pipe 8024, and the other end of the diversion tee pipe 8024 is directly connected to the drain pipe.

[0038] Specifically, one straight port of the discharge tee 8023 is connected to the water distribution pipe 8021 via the second valve body 80231, and the other straight port of the discharge tee 8023 is connected to the right-angle port of the diversion tee 8024 via the third valve body 80232. The sewage discharge pipe is the right-angle port on the discharge tee 8023. Next, a filter cartridge 80261 is installed inside the filter 8026, and the filter cartridge 80261 can be installed and removed from the top of the filter 8026. One straight port of the diversion tee 8024 is connected to one end of the recovery pipe 8022, while the other straight port of the diversion tee 8024 is connected to the elbow 8025. The input end of filter 8026 is connected to one port of bend 8025, and the output end of filter 8026 is connected to reprocessing pipe 8028. A backflushing pipe 8027 is installed on reprocessing pipe 8028 directly opposite the outlet of filter cartridge 80261. A fifth valve body 80281 is installed on one side of reprocessing pipe 8028 via backflushing pipe 8027, and a baffle 8029 for sealing the pipe is installed on the other side of reprocessing pipe 8028 via backflushing pipe 8027. A fourth valve body 80271 is installed on backflushing pipe 8027. It should be noted that all valves used in condensate treatment unit 802 are solenoid valves.

[0039] When air conditioning unit 1 is operating normally, the third valve body 80232 and the fourth valve body 80271 are always closed. When air conditioning unit 1 starts to recover condensate, the first valve body 80221 is opened, and the second valve body 80231 and the third valve body 80232 are closed. The condensate is discharged from the drain pipe 8013 into the recovery pipe 8022 on the water distribution pipe 8021, and then flows through the diversion tee pipe 8024, the elbow pipe 8025 and the filter 8026, and is discharged from the reprocessing pipe 8028 for recycling. When air conditioning unit 1 is shut down and needs cleaning, the control unit starts the flushing unit 804. At this time, the first valve body 80221 and the third valve body 80232 are closed, the second valve body 80231 is opened, and at the same time, the regulating valve 8043 is opened, and pressurized water is sprayed from the flushing nozzle 8044 to flush the inclined inner wall of the sink 8011. The wastewater generated during rinsing is discharged from the drain pipe 8013 into the discharge tee pipe 8023 on the water distribution pipe 8021, and then discharged through the sewage pipe, without contaminating the purified condensate.

[0040] Additionally, after prolonged use, the filter cartridge 80261 requires backflushing to extend its service life. To do this, only the third valve body 80232 and the fourth valve body 80271 are opened, while all other valves are closed. Water flows in through the backflushing pipe 8027, cleaning the filter material from the inside out of the filter cartridge 80261. The filtered material then flows through the bend 8025 to the diversion tee 8024 and from the right-angle opening of the diversion tee 8024 into the drain pipe for discharge.

[0041] In this embodiment, the flushing unit 804 and the condensate treatment unit 802 work together to achieve automatic flushing of the receiving pan 801, effectively removing biological slime from the inner wall of the receiving pan 801, thereby eliminating odor sources in the air and avoiding the risk of blockage of the drain pipe 8013; at the same time, the condensate treatment unit 802 sets up a filter 8026 on the condensate recovery path through the diversion function, ensuring the water quality after condensate recovery and realizing resource utilization.

[0042] Furthermore, since the air conditioning unit 1 adopts the aforementioned frame 9, the overall heat insulation performance of the unit is improved, which in turn leads to an increase in condensate water inside the air conditioning unit 1. Therefore, in this embodiment 1, the condensate water treatment unit 802 effectively solves the problem of water accumulation caused by the increase in condensate water and the risk of condensate water overflowing from the drip tray 801 by collecting and discharging the condensate water. At the same time, the condensate water treatment unit 802, in conjunction with the flushing unit 804, also avoids the long-term retention of water leading to the growth of microorganisms and the formation of biological slime, optimizes the internal environment of the air conditioning unit, and improves the stability and maintenance efficiency of the overall system.

[0043] In summary, the frame 9 structure of the air conditioning unit 1 is improved by using high-strength and corrosion-resistant aluminum profiles as the outer surface of the frame 9, and a decorative panel with low thermal conductivity as the inner surface of the frame 9. Furthermore, a foaming agent is filled into the inner cavity of the frame 9 to improve the heat insulation effect. This effectively blocks the heat conduction of the frame 9 to the cold source, avoids condensation on the outer wall, and also reduces the air leakage rate, thereby improving the overall energy efficiency of the air conditioning unit 1.

[0044] Example 2 is based on Example 1. Since the cooling coil 4, air guide shroud 6, and centrifugal fan 7 all need to be installed within the baffle plate of the water receiving tray 801, horizontal mounting surfaces need to be reserved near the baffle plates on both sides of the sink trough 8011 and drainage trough 8012. These horizontal mounting surfaces are prone to water accumulation. For this purpose, please refer to... Figure 7 and Figure 8 This embodiment adds a drying unit 803 based on embodiment 1, which aims to solve the problem of water accumulation on the horizontal mounting surface of the water receiving tray 801, prevent components or base from rusting due to contact with water, and further enhance the antibacterial and anti-mildew capabilities and drainage efficiency of the air conditioning unit 1.

[0045] See Figure 4 and Figure 8In this embodiment, the drying unit 803 consists of a blower 8031, an air collector 8032, and a hot air duct 8033. The air collector 8032 is located behind the heating coil 3, with its opening facing the heating coil 3. The air collector 8032 can precisely draw in the hot air that has been dehumidified or dried by the heating coil 3. In addition, a mesh cover 80321 is provided at the opening of the air collector 8032 to prevent foreign objects from being sucked in. Next, the input end of the blower 8031 ​​is connected to the air collector 8032 through a suction pipe 80311 to draw in the preheated dry air that has flowed through the heating coil 3. The output end of the blower 8031 ​​is connected to the hot air duct 8033 through an air supply pipe 80312. Subsequently, the hot air duct 8033 is arranged along the inner contour of the water receiving tray 801, and multiple venturi-structured air outlets 80331 are opened on it. These air outlets 80331 are inclined downward and all point to the surface of the sink 8011 and the drain 8012 so as to blow condensate into the sink 8011 and the drain 8012. Part of the water is evaporated due to the drying gas, and the other part of the water is pushed into the sink 8011 and the drain 8012 by the blown dry gas.

[0046] In summary, a drying unit 803 is installed inside the water receiving pan 801. The drying unit 803 forces the hot air generated by the heating coil 3 into the surface of the water receiving pan 801, drying the surface of the water receiving pan 801 when the air conditioner is turned off, thereby inhibiting the growth of microorganisms. In addition, the drying unit 803, together with the drainage groove 8012 opened on the surface of the water receiving pan 801, can also assist in drainage and prevent condensate from accumulating on the surface of the water receiving pan 801.

[0047] In addition, when the air conditioning unit 1 is working normally, the control unit can also intermittently start the blower 8031, so that dry gas is blown out from the air outlet 80331, which can sweep the water droplets accumulated on the surface of the water receiving tray 801 into the drain trough 8012, greatly reducing the water accumulation area and improving drainage efficiency.

[0048] After the rinsing unit 804 completes rinsing, the control unit starts the drying unit 803 to run for 3 to 5 minutes. At this time, the drying gas sent into the water receiving pan 801 can quickly evaporate the moisture on the inner wall surface of the water receiving pan 801, keeping the inner wall of the water receiving pan 801 dry after the air conditioning unit 1 is shut down. This destroys the humid environment required for microbial growth, effectively inhibits the growth of bacteria and mold, and avoids the formation of biological slime.

[0049] Based on Example 1, the drying unit 803 of this embodiment operates according to the following mechanism:

[0050] When the air conditioning unit 1 is running normally, the control condensate treatment unit 802 opens the solenoid valve on the recovery path and closes the solenoid valve on the drain path, so that the condensate flows into the recovery system through the filter 8026.

[0051] When the air conditioning unit 1 stops, the control unit starts the flushing unit 804 and adjusts the flushing water pressure to 0.3 to 0.5 MPa through the PWM signal. At the same time, the solenoid valve on the condensate recovery path of the condensate treatment unit 802 is closed, and all the solenoid valves on the sewage discharge path are opened to form a discharge channel, so that the flushing waste liquid is directly discharged to the sewage pipe.

[0052] After rinsing is completed, the control unit starts the drying unit 803 and controls the blower 8031 ​​to run for 3 to 5 minutes to ensure that the residual moisture on the inner wall is completely evaporated.

[0053] In addition, during the operation of the air conditioning unit 1, a turbidity sensor is installed in the reprocessing pipe 8028 of the condensate treatment unit 802. The turbidity sensor is installed at the front end of the filter 8026, and its detection range is 0-100 NTU with a resolution of 0.1 NTU. During the condensate collection process, the control unit collects the turbidity value in real time. When the detection value exceeds 15 NTU for 3 consecutive seconds, the flushing unit 804 is automatically started to flush the water tray 801. If the turbidity value is lower than 5 NTU, it is determined that the water tray 801 is relatively clean and can enter the drying process to ensure that the water tray 801 is always in a dry and clean state.

[0054] The drying unit 803 in this embodiment not only assists in the drainage of the water tray 801, but also achieves active antibacterial protection.

[0055] Example 3, see Figure 9 This embodiment provides a floor-standing air conditioner, which includes an air conditioning unit 1. The air conditioning unit 1 is equipped with a fresh air inlet 11, a return air inlet 12, and a supply air outlet 13. In this embodiment, the condensate re-isolation system provided in Embodiment 1 or Embodiment 2 is integrated into the air conditioning unit 1.

[0056] Combination Figure 1 As shown, the air conditioning unit 1 contains, in sequence, a filter 2, a heating coil 3, a cooling coil 4, a humidifier 5, an air guide 6, and a centrifugal fan 7. In this embodiment, the water collection assembly 8 is installed at the bottom of the air conditioning unit 1, ensuring that its water collection tray 801 is sized and positioned to completely cover and be positioned below the cooling coil 4, humidifier 5, air guide 6, and centrifugal fan 7. This ensures that water droplets dripping from components that generate condensate inside the air conditioning unit 1 are effectively collected. This avoids problems such as electrical short circuits, metal corrosion, or mold growth caused by condensate leakage inside the unit, greatly improving the overall service life of the unit and the cleanliness of the indoor air supply.

[0057] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
