Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," and "longitudinal" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0045] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0046] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0048] Air handling units (ALUs) are used to improve indoor air temperature, humidity, and air purification levels. ALUs can have a dehumidification function, primarily achieved through a heat exchanger. This heat exchanger operates at a low temperature; when humid air passes through it, the moisture in the air is pre-cooled and condenses into water, thus reducing humidity. ALUs are typically equipped with a built-in condensate collection system to collect the condensate generated during the dehumidification process.

[0049] In unattended work environments, condensate collection devices may leak, and severe leaks could lead to water seepage into the ground, increasing the safety risks of the air handling equipment.

[0050] Based on this, this application provides an air handling device that can provide early warning of water leakage before the air handling device with dehumidification function is installed, so as to improve the safety of the air handling device.

[0051] The air handling equipment 1 provided in this application embodiment can be a dehumidifier, a dehumidifier, an air conditioner, a fresh air unit, or a combined air handling unit.

[0052] Please see Figures 1 to 6 This application provides an air handling device 1, including a body 10, a heat exchange device 20, and a fan assembly 30. The body 10 can be the main shell of the air handling device 1, and the working parts of the air handling device 1, such as the main power supply, the heat exchange device 20, and the fan assembly 30, can be housed inside the body 10. The main power supply can provide electrical energy to the heat exchange device 20 and the fan assembly 30.

[0053] like Figure 2 As shown, the unit 10 can be provided with an air inlet 101 and an air outlet 102, forming an airflow channel between the air inlet 101 and the air outlet 102. The heat exchange device 20 is located within the airflow channel. The fan assembly 30 is used to drive the airflow outside the air handling equipment 1 to enter the interior of the unit 10 through the air inlet 101, and then flow out through the air outlet 102 after passing through the heat exchange device 20. When the high-humidity airflow entering from the air inlet 101 passes through the low-temperature heat exchange device 20, the heat exchange device 20 can convert the moisture in the air from a gaseous state to liquid condensate. The moisture is released from the airflow, thereby reducing the humidity of the airflow. The airflow discharged from the air handling equipment 1 into the indoor environment is a low-humidity airflow. This cycle repeats, and the air humidity in the indoor environment where the air handling equipment 1 is located is reduced, thereby making the indoor environment more livable.

[0054] like Figure 4 As shown, in one possible implementation, the heat exchange device 20 may include a heat exchanger 201, a condenser, and a compressor. The heat exchanger 201 is filled with a heat exchange medium for heat exchange. When the dehumidification function is activated, the refrigerant in the heat exchanger 201 is at a low temperature. When the fan assembly 30 drives airflow through the low-temperature heat exchanger 201, moisture in the air cools and condenses on the surface of the heat exchanger 201, forming condensate. To collect the condensate, a condensate collection assembly 70 may be configured inside the unit 10. The condensate collection assembly 70 may include a drip tray 701 and a built-in water tank located inside the unit 10. If the built-in water tank overflows or shakes, condensate may leak to the outside of the air handling unit 1.

[0055] The air handling device 1 may include a first drainage mode and a second drainage mode. In the first drainage mode, the condensed water accumulated in the body 10 can be discharged to the outside of the body 10, such as by receiving and storing the water in an external water tank outside the body 10, or by discharging the condensed water to a drainage trough in the indoor environment through a drain pipe outside the body 10. The external water tank is not restricted by the volume of the body 10, so the volume of the external water tank can be relatively large, and the drainage trough has the condition for continuous drainage. Therefore, when the air handling device 1 is in the first drainage mode, the heat exchange device 20 of the air handling device 1 can operate for a long time. In the second drainage mode, the condensed water generated by the heat exchanger 201 can be accumulated in the water tank built in the body 10. Due to the volume limitation of the body 10, the volume of the built-in water tank is subject to certain limitations. Therefore, when the air handling device 1 is in the second drainage mode, the frequency of cleaning the built-in water tank may be relatively higher than that of cleaning the external water tank.

[0056] As Figure 2 and Figure 3 shown, for the convenience of description, the external water tank will be referred to as the first water tank 60 and the built-in water tank will be referred to as the second water tank 702 hereinafter. The first water tank 60 can be a water tank supporting the air handling device 1, or other water containers already owned by the user. The second water tank 702 can be at least partially exposed outside the body 10, so that it can be conveniently taken out from the body 10, and the user can discharge and clean the condensed water collected in the second water tank 702.

[0057] In another possible implementation, the heat exchanger 201 may include a dehumidification wheel. When the air handling device 开启除湿功能时, the high-humidity air flow passes through the moisture absorption area of the dehumidification wheel, and the water molecules in the air flow are adsorbed onto the dehumidification wheel. At the same time, another relatively dry and warm regeneration air passes through the regeneration area of the wheel, heating and purging the dehumidification wheel to evaporate the adsorbed moisture, which is discharged with the regeneration air to the external pipeline connected to the air handling device 1, thereby realizing the regeneration and recycling of the dehumidification wheel. The external pipeline is prone to form condensed water and drip when it gets cold, and the external pipeline can introduce the water flow into the first water tank 60. If the first water tank 60 overflows, it is easy to cause a water leakage problem.

[0058] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 shown, the air handling device 1 includes a first drain port 103. The first drain port 103 can be arranged on the body 10 or the water receiving tray 701. The first drain port 103 can be connected to the first water tank 60 outside the body 10 through a drain pipe, so as to discharge the condensed water accumulated inside the body 10 into the larger-volume first water tank 60.

[0059] It is understandable that, since the air handling unit 1 is equipped with a first drain outlet 103, the air handling unit 1 can have a first drain mode with external drainage. In this way, the volume of the unit body 10 can be further compressed, which is conducive to the miniaturization of the entire air handling unit 1.

[0060] In some embodiments, the first drain outlet 103 may be connected to the water receiving tray 701 built into the body 10, thereby discharging the condensate collected in the water receiving tray 701 to the outside of the body 10.

[0061] The water contact detection component 40 is detachably mounted from the body 10. This can be understood as follows: the water contact detection component 40 is completely physically disconnected from the body 10. For example, the water contact detection component 40 can be detached from the body 10 by means of magnetic attraction, snap-fit, threaded connection, plug-in, etc. The water contact detection component 40 can be manually or with the aid of tools to separate from the body 10. Alternatively, the water contact detection component 40 can also be connected to the body 10 through other connection structures (e.g., electrical connection wires, movable connecting rods, etc.) and thus be detachable from the body 10. Alternatively, the water contact detection component 40 can be non-fixedly connected to or non-physically detached from the body 10. The water contact detection component 40 can move / adjust its position relative to the body 10. For example, the water contact detection component 40 can move relative to the body 10 in a certain degree of freedom (e.g., the water contact detection component 40 is hinged or connected to the body 10 via a sliding groove). Although the water contact detection component 40 cannot be completely detached from the body 10, its relative position or angle can be adjusted. This change in position and angle allows the water contact detection component to be placed in the first water tank 60. Because the water contact detection component 40 can be separated from the body 10, its detection range is increased.

[0062] For example, the water contact detection component 40 can be mounted on the body 10 or connected to the body 10 via a connecting structure to prevent loss. Figure 1 and Figure 2 As shown, when the water contact detection component 40 needs to operate, it can be removed from the body 10 and configured to be installed in the first water tank 60, which is used to collect the condensate discharged from the first drain outlet 103. The water contact detection component 40 is used to monitor the potential water leakage risk of the air handling equipment 1. Once a water leakage risk is detected, the air handling equipment 1 can perform at least one of the aforementioned preset operations.

[0063] Specifically, the water contact detection component 40 can be fixed at the target water level of the first water tank 60. When the water in the first water tank 60 rises to the target water level, the water contact detection component 40 generates a water contact status signal, prompting the user to clean the water in the first water tank 60 as soon as possible to prevent water from overflowing and to stop the condensate from being discharged to the outside of the first water tank 60 of the machine body 10, so as to effectively reduce the probability of water leakage.

[0064] The target water level can be close to the top edge of the first water tank 60 to make the most of the water storage space of the first water tank 60 and ensure that the heat exchange device 20 can perform continuous dehumidification.

[0065] like Figure 2 and Figure 5 As shown, the air handling unit 1 may further include an interactive device 80, which may have visual and voice interaction functions. Specifically, the interactive device 80 may include a display panel, a voice module, etc. The interactive device 80 can send visual signals or voice announcements to the user to alert them to the risk of water leakage.

[0066] In some embodiments, the air handling unit 1 may include a control device. The control device may be communicatively connected to the water contact detection component 40 to transmit water contact status signals and control commands.

[0067] For example, the control device can be a microcontroller unit (MCU). The control device is also communicatively connected to the fan assembly 30, heat exchanger 20, and interaction device 80 in the air handling equipment 1 to send control commands to the fan assembly 30, heat exchanger 20, and interaction device 80.

[0068] In some embodiments, when the water contact detection component 40 comes into contact with water, it generates a water contact status signal, and the heat exchange device 20 stops operating based on the water contact status signal.

[0069] Specifically, when the water contact detection component 40 comes into contact with water and generates a water contact status signal, the water contact detection component 40 sends the water contact status signal to the control device. Upon receiving the water contact status signal, the control device generates a shutdown command and sends a shutdown command to the heat exchange device 20 to control the heat exchange device 20 to stop operating. After the heat exchange device 20 stops, it will no longer generate new condensate to prevent the water level in the first water tank 60 from continuing to rise and overflowing.

[0070] Thus, the air handling device 1 provided in this application embodiment is equipped with a water contact detection component 40 that can be separated from the body 10. The water contact detection component 40 can be placed at the target water level of the first water tank 60. Before the first water tank 60 overflows, the water contact detection component 40 can monitor the risk of water leakage that may occur. This can effectively reduce the risk of actual water leakage caused by the overflow of the first water tank 60, thereby effectively reducing the safety risks caused by water leakage and water accumulation in the air handling device 1. Users do not need to clean up the leaks, thereby improving the intelligence level of the air handling device 1, as well as the convenience and safety of users.

[0071] This application embodiment also provides an air handling device 1, which, in addition to including the body 10, heat exchange device 20, fan assembly 30, first drain outlet 103, and water contact detection assembly 40 as described in the above embodiments, such as... Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the air handling unit 1 also includes a second water tank 702. The second water tank 702 is detachably disposed within the unit body 10 and is capable of collecting condensate water within the unit body 10.

[0072] The second water tank 702 can be connected to the water receiving tray 701 inside the body 10. The condensate collected in the water receiving tray 701 can flow into the second water tank 702 when needed. The water contact detection component 40 can be set at the target water level of the first water tank 60 used to receive the water flow discharged from the first drain outlet 103. When water contact occurs, the water contact detection component 40 generates a water contact status signal, the first drain outlet 103 is closed, and the condensate inside the body 10 flows into the second water tank 702.

[0073] When the water level in the first water tank 60 rises to the target water level, the water contact detection component 40 generates a water contact status signal. Upon receiving the water contact status signal, the control device can automatically close the first drain outlet 103 or notify the user to close the first drain outlet 103 to switch the drainage mode from the first drainage mode to the second drainage mode. Alternatively, it can issue a prompt message through the interactive device 80 to use the second water tank 702 built into the body 10 to collect water, thereby reducing the risk of the first water tank 60 overflowing and leaking. This improves the safety and intelligence of the air handling equipment 1 in unattended scenarios.

[0074] In this way, even if the water level in the first water tank 60 rises to the target water level, it is only necessary to switch the drainage mode to drain the condensate into the second water tank 704 to prevent the first water tank 60 from continuing to fill with water and overflowing. The heat exchange device 20 does not need to be shut down, and the dehumidification work can continue to dehumidify the indoor air.

[0075] In some embodiments, the air handling unit 1 includes a switch. The switch may be located at a first drain outlet 103. The switch is used to open or close the first drain outlet 103. When the switch opens the first drain outlet 103, the air handling unit 1 may be in a first drain mode.

[0076] The switching element can be a switching valve, which can automatically open or close the first drain port 103 according to the control command of the control device to automatically start or stop the first drain mode, and the control device can know the working status of the switching valve.

[0077] The switch can be a blocking component. Users can manually operate the switch to open or close the first drain outlet 103. A position sensor can be installed around the switch. The control device can detect whether the switch has opened or closed the first drain outlet 103 through the position sensor.

[0078] In some embodiments, when the first drain outlet 103 is open, the water contact detection component 40 is powered on.

[0079] Specifically, the control device can control the water contact detection component 40 to start based on the opening status of the first drain outlet 103. When the switch (whether it is an automatic switch valve or a user-operated sealing component) opens the first drain outlet 103, the control device can receive the corresponding signal. The control device can actively control the water contact detection component 40 to start and prompt the user to place the water contact detection component 40 in the first water tank 60 through the interactive device 80, reducing the probability that the user will forget to use the water contact detection component to detect the risk of leakage.

[0080] The purpose of this is to proactively monitor for potential leakage risks in the first drainage mode. Since the condensate is led out of the machine body 10 through the first drain port 103, the drainage path is relatively longer and more complex, making leakage more likely. Therefore, it is particularly necessary for the control device to activate the water contact detection component 40 and put it into working condition when the first drain port 103 is open.

[0081] In some embodiments, such as Figure 3 As shown, the air handling unit 1 includes a second drain outlet 7014. The second drain outlet 7014 is disposed on the water receiving tray 701 and is connected to the second water tank 702. The second drain outlet 7014 is used to implement a second drainage mode, discharging condensate into the second water tank 702 built into the unit 10.

[0082] In some embodiments, the second drain outlet 7014 is installed at a higher height than the first drain outlet 103.

[0083] Since the first drain outlet 103 is connected to the low water level of the water collection tray 701, and the second drain outlet 7014 is connected to the high water level of the water collection tray 701, if the first drain outlet 103 is open, condensate will automatically drain through it. After the water contact detection component 40 comes into contact with water and generates a water contact status signal, the control device closes the first drain outlet 103 via a switch, or the control device reminds the user to close the first drain outlet 103 via an interactive device 80. Because the first drain outlet 103 is blocked, the condensate water level accumulated in the water collection tray 701 will continue to rise until it reaches or exceeds the height of the second drain outlet 7014, thus automatically switching to the second drainage mode.

[0084] In this way, the second drain port 7014 can be kept in a normally open state. When switching the drainage mode, only the first drain port 103 needs to be closed, without operating the second drain port 7014, reducing control steps and potential failure points. Furthermore, even if the switch fails to completely close the first drain port 103 due to a malfunction, most of the condensate can still be discharged through the second drain port 7014 because it is in a normally open state, reducing the risk of water overflowing the drip tray 701 and further improving the reliability of the air handling unit 1.

[0085] In some embodiments, such as Figure 3 As shown, the water receiving tray 701 is provided with a water guiding groove 7011 and a connecting groove 7012 connected to the water guiding groove 7011. The connecting groove 7012 connects the first drain outlet 103 and the second drain outlet 7014. A water-blocking rib 7013 is provided in the connecting groove 7012. The second drain outlet 7014 and the first drain outlet 103 are located on both sides of the water-blocking rib 7013, and the height of the second drain outlet 7014 is lower than the free end of the water-blocking rib 7013.

[0086] When the air handling unit 1 is in the first drainage mode, the first drain outlet 103 is opened, and the water guide trough 7011 guides the water flow into the connecting trough 7012 and flows to one side of the first drain outlet 103. Since the second drain outlet 7014 is located on the other side of the water-blocking rib 7013 and its height is lower than the free end of the water-blocking rib 7013, in the first drainage mode, condensate will preferentially be discharged through the first drain outlet 103.

[0087] When the water level in the first water tank 60 reaches the target level, the water contact detection component 40 contacts the water and sends a signal. The control device then closes the switch of the first drain outlet 103, or notifies the user to manually close the first drain outlet 103. With the first drain outlet 103 blocked, the water level in the connecting channel 7012 begins to rise. As the water level gradually rises, the water flow passes over the free end of the baffle 7013 and flows towards the area where the second drain outlet 7014 is located. Condensate flows through the second drain outlet 7014 into the connected second water tank 702, thus switching the drainage mode.

[0088] In some embodiments, the air handling unit 1 further includes a water level detection component. The water level detection component is at least partially disposed in the second water tank 702. When the water level detection component detects that the liquid level in the second water tank 702 has reached the target liquid level, the heat exchange device 20 stops operating.

[0089] When the air handling unit 1 switches to the second drainage mode, condensate begins to flow into the second water tank 702, and the water level in the second water tank 702 gradually rises. The water level detection component continuously monitors the water level inside the second water tank 702. When the water level detection component detects that the liquid level in the second water tank 702 has reached the preset target liquid level, which is usually set close to the position before the second water tank 702 overflows, the water level detection component generates a notification signal and transmits it to the control device.

[0090] Upon receiving the notification signal, the control device will stop the operation of the heat exchanger 20 to prevent the second water tank 702 from overflowing and causing leakage in the air handling unit 1. After the heat exchanger 20 stops operating, no new condensate will be generated, thus reducing the risk of the second water tank 702 overflowing.

[0091] In this way, even without user intervention, the air handling unit 1 can stop the heat exchange device 20 from continuing to dehumidify when the second water tank 702 is full, preventing water leakage and further improving the safety and reliability of the equipment in unattended situations, reducing the inconvenience of users having to frequently check or clean the water tank.

[0092] In some embodiments, when the water contact detection component 40 comes into contact with water, it generates a water contact status signal, and the interactive device 80 issues an alarm message.

[0093] When the control device receives the water contact status signal sent by the water contact detection component 40, it issues a control command to cause the interactive device 80 to sound an alarm. For example, a red fault indicator light may illuminate on the display panel, and the voice module may announce messages such as "Water leak detected, please handle it promptly" to remind the user to pay attention and take appropriate action in a clear and conspicuous manner.

[0094] If the air handling unit 1 is already connected to the user's mobile phone, the user's mobile phone can be considered as the interactive device 80. In this case, when the control device receives a water contact status signal from the water contact detection component 40, in addition to potentially triggering a prompt on the display panel or voice module, the control device will also push alarm information to the user's connected mobile phone via the network. Thus, even if the user is not near the air handling unit 1, they can still be aware of the potential water leakage risk through the alarm information and take appropriate measures as soon as possible.

[0095] It is understood that the alarm message issued by the interactive device 80 and the shutdown of the heat exchange equipment can be performed simultaneously or sequentially, and this application embodiment does not limit this.

[0096] In some embodiments, such as Figure 6 and Figure 7As shown, the air handling unit 1 includes an electrical connection cable 50. The two ends of the electrical connection cable 50 are respectively connected to the water contact detection component 40 and the control device.

[0097] The electrical connection cable 50 can structurally connect the water contact detection component 40 to the body 10, thereby reducing the risk of loss of the water contact detection component 40 without affecting the separation of the water contact detection component 40 from the body 10.

[0098] The electrical connection wire 50 can be used to transmit electrical energy, providing the power required for water contact detection to the water contact detection component 40. This eliminates the need for the water contact detection component 40 to have its own battery, reducing the hassle of battery replacement.

[0099] The electrical connection cable 50 can also be used for communication between the water contact detection component 40 and the control device. When the water contact detection component 40 generates a water contact status signal due to water contact, the water contact status signal can be transmitted to the control device through the electrical connection cable 50. Similarly, the control device can also send commands to the water contact detection component 40 through the electrical connection cable 50. For example, when the first drain outlet 103 is opened or the heat exchange device 20 starts working, the control device can send a power-on command to the water contact detection component 40 through the electrical connection cable 50 to activate the water contact detection component 40.

[0100] In some embodiments, the air handling unit 1 further includes a take-up coil. The take-up coil is disposed on the body 10, and the electrical connection cable 50 is capable of being wound around the take-up coil and released from the take-up coil.

[0101] The reel may include a spring-driven reel with an electrical connection wire 50 wound around it. When the user pulls the water contact detection component 40 out of the body 10, the reel can release the electrical connection wire 50, which is of a certain length to allow the water contact detection component 40 to leave the body 10 and be placed in the first water tank 60.

[0102] The reel can have a self-locking function. When the water contact detection component 40 is placed in position, the ratchet mechanism inside the reel can lock the electrical connection wire 50 to prevent the water contact detection component 40 from springing back.

[0103] When the air handling unit 1 is shut down, the water contact detection component 40 should remain on the unit body 10. By lightly pressing the corresponding button on the unit body 10, the electrical connection cable 50 can be retracted into the unit body 10. The retraction of the electrical connection cable 50 causes the water contact detection component 40 to return to the unit body 10. Furthermore, the electrical connection cable 50 will not become tangled, and the water contact detection component 40 can be accessed at any time.

[0104] In some embodiments, such as Figure 7 , Figure 8 and Figure 10As shown, the water contact detection assembly 40 includes a first electrode 401, a second electrode 402, and a detection circuit board. The first electrode 401 and the second electrode 402 can each be a metal electrode. The first electrode 401 and the second electrode 402 are respectively connected to the detection circuit board. A preset distance exists between the first electrode 401 and the second electrode 402.

[0105] The detection circuit board includes a water contact detection circuit. This circuit monitors changes in resistance or capacitance between the first electrode 401 and the second electrode 402. The circuit applies a weak test voltage (e.g., a few volts) to the two electrodes. In a dry state, the resistance between the first electrode 401 and the second electrode 402 is very high (approaching infinity), and the current in the water contact detection circuit is almost zero. However, when water acts as a conductive medium connecting the first electrode 401 and the second electrode 402, the conductivity of water causes a sharp decrease in resistance between them, resulting in a significant increase in the current flowing through the path between the first and second electrodes.

[0106] The water contact detection circuit may include a signal amplification module and a comparison module. The signal amplification module amplifies the detected current to a manageable level. The amplified detection signal is input to the comparison module, which is configured with a preset threshold. The preset threshold is set based on the minimum expected signal under water contact conditions. When the detection signal exceeds the preset threshold, the output state of the comparison module flips (e.g., changes from low to high).

[0107] The signal output by the comparison module is the water contact status signal. This signal is typically a digital logic level and can be read by the control device. To ensure the reliability of the water contact status signal and prevent false triggering, the water contact detection circuit may include a filtering module (such as a capacitor) to filter out transient interference signals.

[0108] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the water contact detection assembly 40 also includes a housing 403. The housing 403 may be made of engineering plastic material. The detection circuit board is disposed within the housing 403. The first electrode 401 and the second electrode 402 are at least partially exposed outside the housing 403.

[0109] The housing 403 provides structural protection for the detection circuit board, preventing damage from dust, moisture, and physical impacts. The first electrode 401 and the second electrode 402 are at least partially exposed outside the housing 403, thereby enabling leakage risk detection.

[0110] like Figure 7 and Figure 10As shown, the housing 403 includes a water-contact surface 404. When the water contact detection component 40 is placed in the first water tank 60, the water-contact surface 404 readily comes into preferential contact with water.

[0111] like Figure 2 and Figure 8 As shown, the bottom surface of the housing 403 is provided with a water-contact surface 404, and the first electrode 401 and the second electrode 402 are at least partially exposed on the water-contact surface 404. When the water contact detection assembly 40 is placed in the first water tank 60, the water-contact surface 404 with the first electrode 401 and the second electrode 402 contacts the bearing surface. When the water level rises or water leaks and spreads to the water-contact surface 404, the first electrode 401 and the second electrode 402 come into contact with the water surface.

[0112] In some embodiments, the water contact detection assembly 40 includes an energy storage module. The energy storage module is used to store electrical energy and provide power to the detection circuit board.

[0113] The energy storage module can be a capacitor or a small battery. The energy storage module can be pre-charged and release energy during detection, thereby reducing continuous reliance on the main power supply in the air handling unit 1. Thus, as... Figure 1 , Figure 3 , Figure 6 and Figure 9 As shown, the water contact detection component 40 does not need to be connected to the main power supply inside the body 10 via the electrical connection cable 50, that is, it is not limited by the length of the electrical connection cable 50. Therefore, the water contact detection component 40 can be more easily separated from the body 10 and can be placed in the first water tank 60 more flexibly.

[0114] In some embodiments, the energy storage module receives electrical energy transmitted from the main power supply of the air handling unit 1 via a magnetic resonance coupling unit.

[0115] A magnetic resonance coupling unit can be coupled into the detection circuit board, and the magnetic resonance coupling unit may include a receiving coil. The main power supply of the air handling equipment 1 may integrate a transmitting coil, which can drive the transmitting coil to generate an alternating magnetic field. The receiving coil on the detection circuit board can operate at the same resonant frequency as the transmitting coil. When the receiving coil is in the magnetic field generated by the transmitting coil, the receiving coil will induce an alternating current. The current induced by the receiving coil, after rectification and voltage regulation, can charge the energy storage module. The electrical energy is stored by the energy storage module for use by the detection circuit board during the detection process.

[0116] Thus, by integrating a magnetic resonance coupling unit into the detection circuit board, the water contact detection component 40, although dependent on the main power supply, achieves power acquisition without the need for electrical connection wires 50, thereby improving the reliability and placement flexibility of the water contact detection component.

[0117] In some embodiments, the water contact detection component 40 further includes a wireless communication module. The wireless communication module is electrically connected to the detection circuit board and is used to transmit water contact status signals to the control device of the air handling equipment 1 and receive control commands from the control device.

[0118] Specifically, after the detection circuit board generates a water contact status signal, it transmits it to the wireless communication module. The wireless communication module receives the signal, encodes it according to a preset communication protocol (such as Bluetooth, Wi-Fi, Zigbee, etc.), and then transmits it to the control device via the radio frequency module. The corresponding wireless receiving unit on the control device captures and decodes the water contact status signal, thus determining that the water contact detection component 40 has been exposed to water.

[0119] The control device can also send control commands to the wireless communication module as needed via its wireless transmission unit. For example, it can control the water contact detection component 40 to turn on or off. After receiving the control command, the wireless communication module will transmit it to the detection circuit board for execution.

[0120] Thus, by integrating a wireless communication module into the water contact detection component 40, the water contact detection component 40 is freed from the constraints of the electrical connection cable 50, making its installation location more flexible. By integrating an energy storage module and a wireless communication module, the water contact detection component 40 is self-powered during detection, allowing it to operate independently. Simultaneously, through its built-in wireless communication module, the water contact detection component 40 can autonomously transmit the detected water contact status signal wirelessly to the control device of the air handling unit 1. Even when the air handling unit 1 is in a stopped state, if water leakage occurs outside the unit 10, the water contact detection component 40 can still independently perform water contact detection.

[0121] Furthermore, the wireless communication module can directly communicate with the user's mobile phone, enabling water contact status information to be sent to the user's mobile application. This allows the user to remotely monitor the water leakage risk of the air handling unit 1 and receive alarm information, improving the timeliness and reliability of water contact detection.

[0122] In some embodiments, such as Figure 7 , Figure 8 and Figure 10 As shown, the water contact detection assembly 40 also includes a mounting part 405, which is used to assemble the water contact detection assembly 40 to the body 10 and the first water tank 60.

[0123] The mounting portion 405 may be provided or formed in the housing 403. For example... Figure 10 As shown, the mounting part 405 can be a magnetic part. For example... Figure 7 and Figure 8As shown, the mounting part 405 can be a hook part. The mounting part 405 can also be a plug-in part or a clamping part.

[0124] Correspondingly, the body 10 may also be provided with a mating part that is compatible with the mounting part 405, so as to facilitate the fixing of the mounting part 405 to the body 10. The mating part may be a magnetic plate, a slot, a mounting groove 104, etc.

[0125] When the air handling unit 1 is in standby mode, the water contact detection component 40 can be fixed to the body 10 via the mounting part 405 to prevent the water contact detection component from being lost. When the water contact detection component 40 needs to be used, it can also be mounted on the first water tank 60 via the mounting part 405.

[0126] For example, the mounting part 405 can be a hook part. When the air handling unit 1 starts working, the user can hang the water contact detection component 40 on the edge or side wall of the first water tank 60 via the hook part. In this way, when the first water tank 60 is in a state close to full, the water in the first water tank 60 comes into contact with the exposed first electrode 401 and second electrode 402 of the water contact detection component 40, triggering the generation of a water contact status signal.

[0127] In some embodiments, the housing 403 is provided with a receiving groove, and the mounting portion 405 includes two hooks that are movable relative to the housing 403. When the water contact detection component 40 is needed, the hooks can be rotated out from the receiving groove for easy hanging on top, such as the first water tank 60.

[0128] In some embodiments, the body 10 may include a mounting slot 104. The water contact detection component 40 is detachably mounted in the mounting slot 104.

[0129] In some embodiments, the water contact detection component 40 further includes a grip portion 406. The user can remove the water contact detection component 40 from the body 10 or the first water tank 60 and install it onto the first water tank 60 or the body 10 by operating the grip portion 406.

[0130] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
