Description

TECHNICAL AREA

"Several" means two or more than two, unless otherwise specified.

[0036] Air treatment devices are used to improve indoor climate conditions such as air temperature, humidity, and purification level. These devices may include a dehumidification function, primarily achieved through a heat exchanger. This heat exchanger can operate at low temperatures. As humid gas flows through the heat exchanger, the moisture in the gas is condensed upon cooling, thus reducing the humidity. Typically, air treatment devices are equipped with an integrated condensate collection system to collect the condensate produced during the dehumidification process.

[0037] In unattended operating environments, water leaks can occur through the condensate collection system. Severe leaks can lead to ground seepage and thus increase the safety risk to the air handling unit.

[0038] In view of this, the embodiments of the present application provide an air treatment device in which it is possible to detect water leaks or to give an early warning of water leaks for the air treatment device with dehumidification function in order to increase the operational safety of the air treatment device.

[0039] The air treatment device 1 according to the embodiments of the present application can be a dehumidifier, a moisture extractor, an air conditioning system, a fresh air system or a combined ventilation system.

[0040] With reference to Fig. 1 to Fig. Figure 5 provides an embodiment of the present application, an air treatment device 1. The air treatment device comprises a device body 10, a heat exchanger 20, and a blower assembly 30. The device body 10 can serve as the primary outer shell for the air treatment device 1, and operating components of the air treatment device 1, such as the main power supply, the heat exchanger 20, and the blower assembly 30, can be accommodated inside the device body 10. The main power supply can provide electrical energy to the heat exchanger 20 and the blower assembly 30.

[0041] As in Fig. As shown in Figure 2, the device body 10 can be provided with an air inlet 101 and an air outlet 102, with an airflow channel formed between the air inlet 101 and the air outlet 102. The heat exchanger 20 is located inside the airflow channel. The blower assembly 30 drives the external airflow from the air treatment device 1 through the air inlet 101 into the interior of the device body 10, where it flows through the heat exchanger 20 before exiting via the air outlet 102. As the relatively humid airflow entering through the air inlet 101 and flowing through the low-temperature heat exchanger 20 passes through the heat exchanger 20, the heat exchanger 20 converts the moisture in the air from the gaseous state into liquid condensate. This removal of moisture from the airflow reduces its humidity.The airflow released into the interior from the air treatment device 1 is therefore less humid. This process is repeated continuously, thereby reducing the humidity in the interior environment where the air treatment device 1 is located, thus making the interior environment more comfortable.

[0042] As in Fig. As shown in Figure 4, one possible implementation provides for the heat exchanger 20 to comprise a heat exchanger 201, a condenser, and a compressor. The heat exchanger 201 is filled with a heat exchange medium. When the dehumidification function is activated, the refrigerant in the heat exchanger 201 is maintained at a low temperature. As the fan assembly 30 drives an airflow through the low-temperature heat exchanger 201, the moisture in the air, upon cooling, condenses onto the surface of the heat exchanger 201. For condensate collection, the device body 10 can be equipped with a condensate collection assembly 70. The condensate collection assembly 70 can include a water collection disc 701 and an internal water tank located within the device body 10.If the internal water tank overflows or is shaken by movement, this can lead to leakage of condensate from the air treatment device 1 to the outside.

[0043] The air handling device 1 can include a first drainage mode and a second drainage mode. In the first drainage mode, the condensate collected in the device body 10 can be drained to the outside, for example, by collecting and storing water in an external water tank located outside the device body 10, or by draining the condensate through a drain pipe located outside the device body 10 into a drain channel within the interior environment. Since the external water tank is not limited by the volume of the device body 10, it can have a larger capacity, while the drain channel provides the conditions for continuous drainage. Therefore, the heat exchanger 20 of the air handling device 1 can remain in operation for a longer period of time during operation of the air handling device 1 in the first drainage mode.In the second drainage mode, the condensate produced by the heat exchanger 201 can accumulate in the internal water tank of the device body 10. Due to the volume limitations of the device body 10, the capacity of the internal water tank is limited to a certain extent. Therefore, in the second drainage mode of the air treatment device 1, the frequency of cleaning the internal water tank may be relatively higher than that of cleaning the external water tank.

[0044] As in Fig. 2 and Fig. As shown in Figure 3, for the sake of simplicity, the external water tank is referred to below as the first water tank B1 and the internal water tank as the second water tank 702. The first water tank B1 can either be the designated water tank for the air treatment device 1 or another water container already owned by the user. The second water tank 702 can be at least partially exposed to the device body 10, thus facilitating its removal from the device body 10, allowing the user to then drain and dispose of the condensate collected in the second water tank 702.

[0045] In one possible implementation, the heat exchanger 201 is designed to include a dehumidification wheel. When the dehumidification function of the air handling unit 1 is activated, the high-humidity airflow passes through a moisture-absorbing area of ​​the dehumidification wheel, where the water molecules in the airflow are adsorbed by the wheel. Simultaneously, another flow of relatively dry and warmer regeneration air passes through a regeneration area of ​​the wheel, heating and purging the dehumidification wheel to evaporate the adsorbed moisture. This moisture is then discharged, along with the regeneration air, into the external piping connected to the air handling unit 1, thus enabling the regeneration and reuse of the dehumidification wheel. At cold temperatures, the external piping tends to form condensation, which then drips off.Water leaks may occur if there are leaks in the external pipeline or an insufficient seal against the air treatment device 1.

[0046] To mitigate the risk of water leaks and water accumulation in the air treatment device 1 during unattended operation, the air treatment device 1 is equipped with a water contact detection device 40, according to the embodiments of the present application. Upon contact with water, the water contact detection device 40 can generate a water contact status signal and thereby monitors whether a water leak has occurred in the air treatment device 1 or whether there is a risk of a water leak. When the water contact detection device 40 generates a water contact status signal, this indicates that a water leak has occurred in the air treatment device 1 or that there is a risk of a water leak.Preset operations can be performed for the air treatment device 1, which may include: a complete shutdown of the device, a stopping of the operation of the heat exchanger 20, a switch to drainage mode and the transmission of early warning messages, etc. This reduces the risk of water leakage or prevents the spread of a water leak that has already occurred.

[0047] The water contact detection assembly 40 is configured to be separable from the device body 10. This means that the physical connection between the water contact detection assembly 40 and the device body 10 is completely severed. The water contact detection assembly 40 can be attached to the device body 10, for example, by magnetic attraction, a snap connection, a threaded connection, a plug connection, etc. The water contact detection assembly 40 can be detached from the device body 10 manually or with the aid of tools. Alternatively, the water contact detection assembly 40 can be connected to the device body 10 via other connection structures (e.g., an electrical connecting wire, a movable connecting rod, etc.) and be separable relative to the device body 10.Alternatively, the water contact detection arrangement 40 can be neither rigidly connected to nor physically detached from the device body 10, allowing the water contact detection arrangement 40 to move / adjust its position relative to the device body 10. For example, the water contact detection arrangement 40 is designed to move relative to the device body 10 with a certain degree of freedom (e.g., the water contact detection arrangement 40 is articulated relative to the device body 10 or attached by a sliding rail connection). In this case, the water contact detection arrangement 40 cannot be completely separated from the device body 10, but its relative position or angle can be adjusted. This change in position and angle makes it possible to position the water contact detection arrangement either at the target area A or at the target object B.Since the water contact detection arrangement 40 can be separated from the device body 10, the detection area of ​​the water contact detection arrangement 40 is increased.

[0048] For example, the water contact detection arrangement 40 can be attached to the device body 10 or connected to the device body 10 via a connecting structure to prevent loss. As shown in Fig. 1 and Fig. As shown in Figure 2, when the water contact detection arrangement 40 is to be put into operation, it can be removed from the device body 10 and positioned in the target area A or on the target object B to monitor potential water leakage risks in the air treatment device 1. As soon as a water leakage has occurred or there is a risk of water leakage, the air treatment device 1 can perform at least one of the above-mentioned preset operations.

[0049] As in Fig. As shown in Figure 1, one possible implementation provides that the target area A can be a support surface for carrying the device body 10. In particular, the target area A can be an area that has a predetermined distance to the device body 10 within the support surface.

[0050] The support surface can be any surface within an indoor environment that can support the device body 10, such as the floor, a tabletop, or the surface of furniture on which the air treatment device 1 is placed. The target area A can be a support surface or be located within the support surface.

[0051] Furthermore, the target area A can be an area located at a predetermined distance from the device body 10 in the wing. If a water leak occurs in the air handling device 1, the condensate typically spreads radially from the device body 10, which is considered the center point, with the extent of the water leak being directly proportional to its duration. The target area A is positioned at a predetermined distance from the device body 10. As soon as the condensate reaches the target area A (which typically takes 1 to 3 minutes), the water contact detection arrangement 40 can immediately generate a water contact status signal. The air handling device then immediately performs preset operations or prompts the user to dispose of the water and take appropriate action.

[0052] If the water contact detection arrangement 40 is connected to the device body 10 via an electrical connection cable, the length of the electrical connection cable must be greater than the predetermined distance. If the water contact detection arrangement 40 communicates wirelessly with the control unit 90, the communication range of the water contact detection arrangement 40 must exceed the predetermined distance.

[0053] In one possible implementation, the device body 10 of the air treatment device 1 can be suspended from a wall within an indoor environment. The target area A can be a floor surface opposite the device body 10 in its suspended state. In particular, the target area A can be defined as an area on the floor surface whose center point is the vertical projection of the device body 10 and which is located at a predetermined distance from the center point.

[0054] In particular, the target area A can be defined as an approximately semicircular region whose center point is the vertical projection of the device body 10 onto the floor surface and which extends to a predetermined distance. When the second water tank 702 of the air treatment device 1 is completely filled with condensate, the condensate drips onto the floor surface, forming a spreading water stain whose center point lies on the vertical projection of the device body 10 (within the target area A). Upon water contact, the water contact detection arrangement 40 can generate a water contact status signal, and the air treatment device 1 then performs the preset operations to prevent the risk of the water leak spreading and prompts the user to dispose of the spill and take appropriate action.

[0055] In particular, the aforementioned predetermined distance may be less than 10 cm to avoid a reaction delay caused by the water contact detection arrangement 40 being positioned too far from the device body 10.

[0056] It should be noted that the target area A can be determined based on the user's experience or, alternatively, be visually displayed to the user via the air handling device 1. For example, the device body 10 can be equipped with light-emitting diodes (LEDs). When the air handling device receives a feedback signal indicating that the water contact detection arrangement 40 has been switched on, the light emitted by these LEDs is projected onto the wing or wall surface. This visually displays the target area A, allowing users to identify the target area A for the water contact detection arrangement 40.

[0057] As in Fig. As shown in Figure 2, in some embodiments the target object B can be a first water tank B1. When the air treatment device 1 is in first drainage mode, the water contact detection arrangement 40 can be fixed at a target water level in the first water tank B1. When the water in the first water tank B1 reaches this target water level, the water contact detection arrangement 40 generates a water contact status signal upon contact with water. This allows the heat exchanger 20 to stop its operation. The interaction device 80 can then indicate to the user that the accumulated water should be removed from the first water tank B1 as quickly as possible to prevent overflow.Alternatively, the air treatment device 1 can automatically switch to the second drainage mode and stop the drainage of condensate into the external first water tank B1 of the device body 10, thereby effectively reducing the risk of water leakage.

[0058] The target water level can be set near the top edge of the first water tank B1 to make optimal use of the storage capacity of the first water tank B1 and thus ensure that the heat exchanger 20 can perform a continuous dehumidification treatment.

[0059] By positioning the water contact detection device 40 at the target water level in the first water tank B1, the air treatment device 1 can execute preset operations before a water leak occurs. The water contact detection device 40 monitors for impending water leakage risks, effectively mitigating the danger of overflow and subsequent leakage from the first water tank B1. This eliminates the need for the user to remove spilled water, thus increasing the intelligence and ease of use of the air treatment device 1. Even when the water level in the first water tank B1 reaches the target level, the drainage mode can be switched to drain the condensate into the second water tank 702.This prevents further water from flowing into the first water tank B1 and avoids overflow, allowing the heat exchanger 20 to operate continuously without shutdown. Dehumidification can therefore continue uninterrupted to maintain continuous dehumidification of the room air.

[0060] As in Fig. As shown in Figure 3, in some embodiments the air treatment device 1 may be equipped with a movable base B2 for supporting the device body 10, wherein the target object B may be the movable base B2.

[0061] The movable base B2 can have rollers, which makes it easier for the movable base B2 to move the device body 10 to the target position where dehumidification is required, thereby reducing the humidity at that target position.

[0062] The water contact detection arrangement 40 can be arranged on the movable base B2. In the event of a water leak from the second water tank 702 of the air treatment device 1, e.g., when the second water tank 702 is full, when the second water tank 702 overflows due to fluctuations during movement, or when there is a loose connection between the second water tank 702 and the water collection disc 701, the water overflowing from the device body 10 flows onto the surface of the movable base B2. The water contact detection arrangement 40, arranged on the movable base B2, then comes into contact with the water and generates a water contact status signal.

[0063] Because the water contact detection arrangement 40 is located on the movable base B2, the water contact status signal can be emitted as soon as water droplets accumulate but have not yet spread across the floor surface. This effectively reduces the risk of water leaks in the air treatment device 1, improves the adaptability of the air treatment device 1 to complex operating environments, and ensures the cleanliness of the indoor environment.

[0064] As in Fig. As shown in Figure 5, the air treatment device 1 can further comprise an interaction device 80, wherein the interaction device 80 can have both visual and speech interaction functions. In particular, the interaction device 80 can include a display panel, a speech module, etc. The interaction device 80 can issue a visual signal or a speech warning to the user to indicate potential water leaks or leakage risks.

[0065] By equipping the air treatment device 1 with the water contact detection arrangement 40 according to the embodiments of the present application, wherein the water contact detection arrangement 40 can be detached from the device body 10 and positioned in the target area A or target object B, it is possible for the water contact detection arrangement 40 not only to immediately detect actual water leaks but also to send an early warning message of potential water leakage risks. This creates a multi-stage leakage monitoring function for the air treatment device 1, thereby effectively mitigating safety risks to the air treatment device 1 caused by water leaks or water accumulation. Furthermore, this increases the intelligence level of the air treatment device 1 and improves user comfort and the sense of security for the users.

[0066] In some embodiments, the air treatment device 1 may include a control unit 90. The control unit 90 can communicate with the water contact detection arrangement 40 to transmit a water contact status signal and a control instruction.

[0067] For example, the control unit 90 can be a microcontroller unit 90MCU (microcontroller unit 90). The control unit 90 also communicates with the blower assembly 30, the heat exchanger 20, and the interaction unit 80 within the air handling device 1 to send control instructions to the blower assembly 30, the heat exchanger 20, and the interaction unit 80.

[0068] In some embodiments, it is provided that the heat exchanger 20 stops its operation depending on the water contact status signal when the water contact detection arrangement 40 generates the water contact status signal upon water contact.

[0069] In particular, when the water contact detection device 40 generates a water contact status signal upon water contact, it transmits this signal to the control unit 90. Upon receiving the water contact status signal, the control unit 90 generates a shutdown instruction and sends it to the heat exchanger 20 to control its operation and stop it. After the heat exchanger 20 is shut down, no further condensate is produced. This prevents the leakage area from expanding if a water leak has already occurred. Furthermore, in the event of imminent water leakage risks, the escalation of risks that could lead to a water leak can be mitigated.

[0070] In some embodiments, the interaction device 80 is provided to send an early warning message when the water contact detection arrangement 40 generates the water contact status signal upon water contact.

[0071] Upon receiving the water contact status signal emitted by the water contact detection device 40, a control instruction is issued, causing the interaction device 80 to send an early warning message as an alarm. For example, a red error indicator may light up on the display panel, while the voice module issues an early warning message with content such as "Water leak detected, please take immediate action" to clearly and unambiguously alert the user and prompt them to take appropriate action.

[0072] If the air treatment device 1 is networked and paired with the user's mobile phone, the user's mobile phone can be considered an interaction device 80. Under such circumstances, when the control device 90 receives the water contact status signal emitted by the water contact detection device 40, it can issue a notification by triggering a display or voice module. Additionally, the control device 90 sends an early warning message over the network to the user's registered mobile phone. Even if the user is not near the air treatment device 1, the early warning message allows them to be informed in a timely manner of a water leak or a potential risk of leakage, enabling them to take appropriate action as quickly as possible.

[0073] It is understood that the output of an early warning message by the interaction device 80 and the stopping of the operation of the heat exchange device 20 can occur simultaneously or sequentially, which is not limited in the embodiments of the present application.

[0074] As in Fig. 2 and Fig. As shown in Figure 5, in some embodiments the air treatment device 1 further comprises a first drain outlet 103. The first drain outlet 103 is provided in the device body. The first drain outlet 103 can be connected to the first water tank B1 via a drain pipe, whereby the condensate collected in the device body 10 is drained into the first water tank B1, which has a larger volume.

[0075] It is understandable that the air treatment device 1 can have a first drainage mode in which water is discharged to the outside, since the air treatment device 1 is equipped with the first drain outlet 103. This allows the volume of the second water tank 702 to be further reduced, which facilitates the overall miniaturization of the air treatment device 1.

[0076] In some embodiments, the first drain outlet 103 can be connected to the water collection disc 701 integrated into the device body 10, whereby the condensate collected in the water collection disc 701 is drained out of the device body 10 to the outside.

[0077] In some embodiments, the air treatment device 1 may further include a switching element. The switching element may be arranged at the first drain outlet 103. The switching element serves to open or close the first drain outlet 103. When the switching element opens the first drain outlet 103, the air treatment device 1 may be in the first drainage mode.

[0078] The switching element can be a switching valve that, depending on the control instruction of the control unit 90, can automatically open or close the first drain outlet 103 in order to automatically start or end the first drainage mode. Furthermore, the control unit 90 can thereby determine the operating status of the switching valve.

[0079] The switching element can be a locking element, allowing the user to manually actuate it to open or close the first drain outlet 103. A position sensor can be arranged around the switching element so that the control unit 90 can determine via the position sensor whether the switching element has opened or closed the first drain outlet 103.

[0080] In some embodiments, the water contact detection arrangement 40 is in an on state when the first drain outlet 103 is open.

[0081] In particular, the control unit 90 can control the activation of the water contact detection device 40 depending on the opening state of the first drain outlet 103. When the switching element (be it the automatic switching valve or the user-operated blocking element) opens the first drain outlet 103, the control unit 90 can receive a corresponding signal. The control unit 90 can then proactively control the water contact detection device 40 to activate and prompt the user to position the water contact detection device 40 in the target object B (e.g., the first water tank B1). This reduces the likelihood that the user will forget to use the water contact detection device to detect water leakage risks.

[0082] This aims to proactively monitor potential water leakage risks in the first drainage mode. Since the condensate is drained out of the device body 10 via the first drain outlet 103, the drainage path becomes comparatively longer and more complex, thus increasing the susceptibility to water leaks. For example, if there is a loose connection between the drain pipe and the first drain outlet 103, or if water leakage occurs due to aging of the drain pipe, it is particularly important that the control unit 90 activates and maintains the water contact detection arrangement 40 when the first drain outlet 103 is open.

[0083] In some embodiments, the water contact detection arrangement 40 is activated and switched on when the heat exchanger 20 is started.

[0084] When the heat exchanger 20 is started, condensation is produced. Therefore, when the heat exchanger 20 is started, there is a possibility of an accidental condensation leak due to an overflow from the second water tank 702 or a loose connection at the first drain outlet 103.

[0085] The control unit 90 can monitor a start signal from the heat exchanger 20. Regardless of whether the air treatment device 1 is in first or second drainage mode, the control unit 90 proactively activates the water contact detection device 40 upon receiving the start signal, thereby switching it on and enabling it to function. Combined with the instruction that the user positions the water contact detection device 40 within target area A or target object B, this allows for the monitoring of any spilled water or the risk thereof.

[0086] Regardless of whether the first drain outlet 103 is open, the water contact detection arrangement 40 can thus detect the occurrence of a water leak or the risk of a water leak in a timely manner and generate a water contact status signal. The air treatment device 1 then performs the preset operations, thereby reducing the risk of the water leak escalating or increasing in extent.

[0087] In some embodiments, the air treatment device 1 may further comprise a humidity sensing arrangement. The humidity sensing arrangement is arranged on the device body 10, and the humidity sensing arrangement serves to obtain an ambient humidity value.

[0088] The humidity sensing arrangement communicates with the control unit 90. When either of the two conditions is met, i.e., when the ambient humidity measured by the humidity sensing arrangement reaches a preset threshold or the water contact sensing arrangement 40 generates a water contact status signal, the control unit 90 can control the heat exchanger 20 to stop operation.

[0089] When the ambient humidity measured by the humidity sensor reaches the preset threshold, this means that the current humidity is already within the user-defined range. Since the room humidity remains stable, continued dehumidification may be unnecessary and could lead to an excessively dry environment. The control unit 90 controls the shutdown of the heat exchanger 20, thus reducing unnecessary energy consumption and maintaining the ambient humidity within a relatively comfortable range.

[0090] The water contact status signal generated by the water contact detection arrangement 40 indicates that a water leak has already occurred and there is a risk of water leakage, so that further condensation can be stopped by immediately switching off the heat exchanger device 20.

[0091] By combining humidity sensing with water leakage risk detection, the control unit 90 can manage the operating status of the heat exchanger unit 20 more intelligently. The air handling unit 1 is able to react to real-time environmental changes and the potential water leakage risk, thereby achieving safer and more energy-efficient control.

[0092] In some embodiments, the water contact detection arrangement 40 can be positioned at the target water level in the first water tank B1, which serves to collect water discharged from the first outlet 103. When the water level in the first water tank B1 rises to the target water level, the water contact detection arrangement 40 generates a water contact status signal upon contact with water. Depending on this water contact status signal, the heat exchanger 20 ceases its operation.

[0093] By positioning the water contact detection device 40 at the target water level in the first water tank B1, the control unit 90 can control the heat exchanger 20 to stop operation before a water leak actually occurs. This effectively reduces the risk of overflow and spillage caused by the further collection of water by the first water tank B1. This eliminates the need for the user to remove spilled water, thus increasing the intelligence and ease of use of the air treatment device 1.

[0094] As in Fig. 2 and Fig. As shown in Figure 7, in some embodiments the air treatment device 1 further comprises a second water tank 702. The second water tank 702 is arranged in the device body 10, and the second water tank 702 can collect the condensate in the device body 10.

[0095] The second water tank 702 can be connected to the water collection disc 701 arranged in the device body 10, causing the condensate collected in the water collection disc 701 to flow into the second water tank 702. The water contact detection arrangement 40 can be positioned at the target water level in the first water tank B1, which serves to collect water discharged from the first drain outlet 103. Upon water contact, the water contact detection arrangement 40 generates a water contact status signal, causing the switching element to close the first drain outlet 103 and allowing the condensate within the device body 10 to flow into the second water tank 702.

[0096] When the water level in the first water tank B1 rises to the target water level, the water contact detection arrangement 40 generates a water contact status signal upon water contact. Upon receiving this signal, the control unit 90 can then control the switching element to close the first drain outlet 103, thus automatically switching from the first drainage mode to the second drainage mode. Alternatively, the interaction device 80 issues a notification to the user, prompting them to manually actuate the switching element to close the first drain outlet 103 and switch to the second drainage mode. This allows water to be collected via the second water tank 702, which is integrated into the device body 10, thereby reducing the risk of overflow and leakage from the first water tank B1.This increases the operational safety and intelligence of the air handling unit 1 in unattended scenarios. In this way, the heat exchanger 20 can operate continuously without shutdown. Dehumidification can thus continue uninterrupted to maintain continuous dehumidification of the room air.

[0097] As in Fig. As shown in Figure 7, in some embodiments the air treatment device 1 further comprises a second drain outlet 7014. The second drain outlet 7014 is arranged in the water collection disc 701, and the second drain outlet 7014 is connected to the second water tank 702. The second drain outlet 7014 serves to achieve the second drainage mode, so that the condensate is drained into the second water tank 702 within the device body 10.

[0098] In some embodiments, the second drain outlet 7014 is positioned higher than the first drain outlet 103.

[0099] Since the first drain outlet 103 is connected to the water collection disc 701 at low water levels, and the second drain outlet 7014 is connected to the water collection disc 701 at high water levels, the condensate automatically drains through the first drain outlet 103 when the first drain outlet 103 is open. After the water contact detection arrangement 40 generates a water contact status signal, the control unit 90 closes the first drain outlet 103 via the switching element. Because the first drain outlet 103 is blocked, the condensate level in the water collection disc 701 continues to rise until it reaches or exceeds the height of the second drain outlet 7014. This triggers an automatic switchover to the second drainage mode.

[0100] Thus, the second drain outlet 7014 can remain in a normally open state. When switching between drainage modes, only the first drain outlet 103 needs to be closed, without requiring any actuation of the second drain outlet 7014. This reduces the number of control steps and potential sources of error. Even if the switching element cannot completely close the first drain outlet 103 due to a malfunction, most of the condensate can still be drained via the second drain outlet 7014 because the second drain outlet 7014 normally remains open. This reduces the risk of the water collection disc 701 overflowing, further increasing the reliability of the air treatment device 1.

[0101] In some embodiments, such as in Fig. As shown in Figure 7, the water collection disc 701 comprises a water guide slot 7011 and a connecting slot 7012, which is connected to the water guide slot 7011. The connecting slot 7012 connects the first drain outlet 103 to the second drain outlet 7014, with a water retention rib 7013 being provided within the connecting slot 7012. The second drain outlet 7014 and the first drain outlet 103 are located on opposite sides of the water retention rib 7013. The height of the second drain outlet 7014 is also lower than a free end of the water retention rib 7013.

[0102] When the air treatment device 1 is in the first drainage mode, the first drain outlet 103 opens, and the water guide slot 7011 directs the water flow into the connecting slot 7012, where it flows to the side of the first drain outlet 103. Since the second drain outlet 7014 is located on the opposite side of the water retention rib 7013 and its height is lower than the free end of the water retention rib 7013, the water in the first drainage mode is primarily drained through the first drain outlet 103.

[0103] When the water level in the first water tank B1 reaches the target water level, the water contact detection device 40 comes into contact with the water and sends a signal. The control unit 90 then deactivates the switching element for the first drain outlet 103 or prompts the user to close the first drain outlet 103 manually. Because the first drain outlet 103 is blocked, the water level in the connection slot 7012 begins to rise. As the water level gradually rises, the water flows over the free end of the water retention rib 7013 and then flows towards the area where the second drain outlet 7014 is located. The condensate then flows through the second drain outlet 7014 into the connected second water tank 702, thus switching the drainage mode.

[0104] In some embodiments, the air treatment device 1 further comprises a water level sensing arrangement. The water level sensing arrangement is at least partially located in the second water tank 702. When the water level sensing arrangement detects that the liquid level in the second water tank 702 has reached the target liquid level, the heat exchanger 20 ceases operation.

[0105] When the air treatment device 1 is switched to the second drainage mode, the condensate begins to flow into the second water tank 702, causing the water level in the second water tank 702 to gradually rise. The water level sensing arrangement continuously monitors the water level in the second water tank 702. When the water level sensing arrangement detects that the liquid level in the second water tank 702 has reached the preset target liquid level, which is typically set near the point just before the second water tank 702 overflows, the water level sensing arrangement generates a notification signal and transmits it to the control unit 90.

[0106] Upon receiving the notification signal, the control unit 90 controls the heat exchanger 20 to stop operation in order to prevent the second water tank 702 from overflowing and subsequently leaking water from the air treatment device 1. After the heat exchanger 20 stops operating, no further condensate is produced, thus reducing the risk of overflow from the second water tank 702.

[0107] Thus, even without user intervention, the air handling unit 1 can prevent the heat exchanger 20 from continuing dehumidification when the second water tank 702 is almost full, thereby preventing water from leaking out. This further increases the safety and reliability of the device during unattended operation while simultaneously reducing the effort required for frequent water tank checks or cleaning by the user.

[0108] In some embodiments, the water contact detection arrangement 40 is arranged to be detachable from the device body 10. The water contact detection arrangement 40 can generate a water contact status signal upon contact with water. The water contact detection arrangement 40 can be integrated into the movable base B2, which serves to support the device body 10.

[0109] The air treatment device 1 can be a portable, compact unit and can be equipped with the movable base B2. The movable base B2 can be fitted with casters to facilitate the user's movement of the air treatment device 1. The water contact detection arrangement 40 is integrated into the movable base B2. Should condensation unexpectedly leak from the bottom of the device body 10 or from any other point onto the movable base B2 during operation of the air treatment device 1, the water contact detection arrangement 40 integrated into the movable base B2 generates a water contact status signal upon contact with water. To prevent further propagation of the water leakage, the control unit 90 can control the heat exchanger 20 to stop operation or control the air treatment device 1 to temporarily suspend its function.

[0110] As in Fig. 2 and Fig. As shown in Figure 8, in some embodiments the air treatment device 1 further comprises an electrical connecting line 50. The electrical connecting line 50 is connected at both ends to the water contact detection arrangement 40 and the control unit 90, respectively.

[0111] The electrical connecting line 50 structurally connects the water contact detection arrangement 40 to the device body 10, thereby reducing the risk of the water contact detection arrangement 40 being lost, without, however, affecting the separable configuration of the water contact detection arrangement 40 from the device body 10.

[0112] The electrical connecting line 50 can be used to transmit electrical energy to supply the water contact detection arrangement 40 with the electrical energy required for water contact detection. Thus, the water contact detection arrangement 40 does not require its own battery, eliminating the need for battery replacement.

[0113] The electrical connection line 50 can also be used for communication between the water contact detection arrangement 40 and the control unit 90. When the water contact detection arrangement 40 generates a water contact status signal upon water contact, this signal can be transmitted to the control unit 90 via the electrical connection line 50. Similarly, the control unit 90 can also transmit an instruction to the water contact detection arrangement 40 via the electrical connection line 50. For example, when the first drain outlet 103 is opened or the heat exchanger 20 starts operating, the control unit 90 can send a start instruction to the water contact detection arrangement 40 via the electrical connection line 50 to activate it.

[0114] In some embodiments, the air treatment device 1 further comprises a reel. The reel is arranged on the device body 10, and the electrical connecting cable 50 can be wound onto and unwound from the reel.

[0115] The reel can include a spring-driven roller onto which the electrical connecting cable 50 is wound. When the user pulls the water contact detection assembly 40 out of the device body 10, the roller releases the electrical connecting cable 50. The electrical connecting cable 50 is long enough to allow the water contact detection assembly 40 to move a predetermined distance away from the device body 10 and thus into the target area A.

[0116] The roller can have a self-locking function. Once the water contact detection assembly 40 is positioned in place, a ratchet mechanism inside the roller can lock the electrical connecting line 50, thus preventing the water contact detection assembly 40 from springing back.

[0117] When the air treatment device 1 is switched off, the water contact detection device 40 must remain attached to the device body 10. When the corresponding button on the device body 10 is lightly pressed, the electrical connecting cable 50 is retracted into the interior of the device body 10. As the electrical connecting cable 50 retracts, it causes the water contact detection device 40 to reset itself onto the device body 10. Furthermore, the electrical connecting cable 50 does not become tangled, so the water contact detection device 40 remains accessible at all times.

[0118] As in Fig. 6, Fig. 8 and Fig. As shown in Figure 9, in some embodiments the water contact detection arrangement 40 comprises a first electrode 401, a second electrode 402, and the 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 can each be connected to the detection circuit board. There is a predetermined distance between the first electrode 401 and the second electrode 402.

[0119] The sensing circuit board includes a water contact sensing circuit. This circuit is used to monitor changes in resistance or capacitance between the first electrode 401 and the second electrode 402. The water contact sensing circuit can apply a weak test voltage (e.g., a few volts) to the two electrodes. In the dry state, the resistance between the first electrode 401 and the second electrode 402 is extremely high (near infinite), resulting in a near-zero current within the water contact sensing circuit. When water acts as the conductive medium between the first electrode 401 and the second electrode 402, the conductivity of the water causes the resistance between these electrodes to decrease significantly. Consequently, the current flowing through the path between the first and second electrodes increases considerably.

[0120] The water contact detection circuit can include a signal amplification module and a comparator module. The signal amplification module boosts the detected current to a manageable level. The amplified detection signal is then fed into the comparator module, which is configured with a preset threshold. This preset threshold is determined based on the minimum expected signal in the water contact state. When the detection signal exceeds the preset threshold, an output state of the comparator module reverses (e.g., from a low level to a high level).

[0121] The signal output by the comparator module constitutes the water contact status signal. This water contact status signal is typically a digital logic level and can be read by the control unit 90. To ensure the reliability of the water contact status signal and prevent false triggering, the water contact detection circuit may include a filter module (e.g., a capacitor) to filter out transient interference signals.

[0122] As in Fig. 6, Fig. 8 and Fig. As shown in Figure 9, in some embodiments the water contact detection arrangement 40 further comprises a housing 403. The housing 403 can be made of engineering plastic. The detection circuit board is arranged in the housing 403. The first electrode 401 and the second electrode 402 are at least partially exposed outside the housing 403.

[0123] The housing 403 provides structural protection for the detection circuit board and prevents damage to the detection circuit board from dust, moisture, and physical impacts. The first electrode 401 and the second electrode 402 are at least partially exposed outside the housing 403, thus enabling contact with water within the target area A or the target object B for water contact detection.

[0124] As in Fig. 6 and Fig. As shown in Figure 8, the housing 403 includes a water contact surface 404. When the water contact detection arrangement 40 is positioned within the target area A or the target object B, the water contact surface 404 tends to preferentially contact with water.

[0125] As in the Fig. 1, Fig. 3 and Fig. As shown in Figure 6, the underside of the housing 403 has a water contact surface 404, with the first electrode 401 and the second electrode 402 projecting at least partially beyond the water contact surface 404. When the water contact detection arrangement 40 is positioned within the target area A, this water contact surface 404, which supports the first electrode 401 and the second electrode 402, comes into contact with the wing. As the water level rises or spilled water spreads onto the water contact surface 404, the first electrode 401 and the second electrode 402 come into contact with water.

[0126] As in Fig. As shown in Figure 8, the water contact surface 404 can alternatively be positioned at the base of the housing 403. As shown in the Fig. 2 and Fig. As shown in Figure 8, when the water level inside the target object B rises, the water first saturates the water contact surface 404 and then quickly comes into contact with the first electrode 401 and the second electrode 402, which are exposed outside the housing 403.

[0127] As in Fig. 3 and Fig. As shown in Figure 6, in some embodiments the water contact surface 404 is able to support the water contact detection arrangement 40 positioned within the target area A.

[0128] The water contact surface 404 enables the water contact detection arrangement 40 to be stably supported within the target area A, thus preventing the water contact detection arrangement 40 from shifting or tipping over. Since the water contact surface 404 has a function for physically supporting the water contact detection arrangement 40, the water contact surface 404 can serve as a preferred surface for water contact within the target area A or within the target object B.

[0129] For example, the water contact surface 404 can be a flat surface, a structured surface, or a specific concave-convex structure to ensure the stability of the water contact detection arrangement.

[0130] In some embodiments, the detection circuit board includes an energy storage module. The energy storage module serves to store electrical energy and is connected to the detection circuit board. It also serves to store electrical energy and supply power to the detection circuit board.

[0131] The energy storage module can comprise a capacitor or a compact battery. This energy storage module can be pre-charged and supply electrical energy during the sensing process, thereby reducing the continuous dependence on the main power supply for the air handling device 1. As described in the Fig. 1, Fig. 3, Fig. 6 and Fig. As shown in Figure 9, the water contact detection arrangement 40 can therefore no longer be connected to the main power supply within the device body 10 via the electrical connecting cable 50. Consequently, it is not limited by the length of the electrical connecting cable 50. This facilitates the simpler separation of the water contact detection arrangement 40 from the device body 10, so that the water contact detection arrangement 40 can be positioned more flexibly either at the target area A or the target object B.

[0132] In some embodiments, the energy storage module receives electrical energy transmitted via the magnetic resonance coupling unit from the main power supply of the air treatment device 1.

[0133] The magnetic resonance coupling unit can be coupled within the sensing circuit board, and the magnetic resonance coupling unit can include a receiving coil. The main power supply for the air handling device 1 can accommodate an integrated transmitting coil. This main power supply can drive the transmitting coil to generate an alternating magnetic field, thereby enabling the receiving coil on the sensing circuit board to operate at the same resonant frequency as the transmitting coil. When the receiving coil is located within the magnetic field generated by the transmitting coil, an alternating current is induced in the receiving coil. The current induced in the receiving coil is rectified and regulated to charge the energy storage module, which stores electrical energy for use by the sensing circuit board during sensing.

[0134] By integrating the magnetic resonance coupling unit into the detection circuit board, the water contact detection arrangement 40, which is powered from the main power supply, achieves a power supply without an electrical connecting line 50. This increases the reliability and flexibility in the placement of the water contact detection arrangement.

[0135] In some embodiments, the water contact detection arrangement 40 further comprises a wireless communication module. The wireless communication module is electrically connected to the detection circuit board and serves to transmit the water contact status signal to the control unit 90 of the air treatment device 1 and to receive a control instruction from the control unit 90.

[0136] In particular, when the detection circuit board generates a water contact status signal and transmits it to the wireless communication module, the wireless communication module detects the water contact status signal. It then encodes the signal according to a preset communication protocol (such as Bluetooth, Wi-Fi, Zigbee, etc.) before transmitting it to the control unit 90 via a radio frequency module. The corresponding wireless receiver on the control unit 90 detects and decodes the water contact status signal, thereby determining that the water contact detection arrangement 40 is ready to be in contact with water.

[0137] The control unit 90 can also send a control instruction to the wireless communication module via its wireless transmitter unit if required. For example, the water contact detection arrangement 40 is controlled to be switched on or off. After receiving the control instruction, the wireless communication module transmits this control instruction to the detection circuit board for execution.

[0138] By integrating the wireless communication module into the water contact detection arrangement 40, this water contact detection arrangement 40 is freed from the limitations imposed by the electrical connecting cable 50, thus achieving greater flexibility regarding the installation location of the water contact detection arrangement 40. Because the energy storage module and the wireless communication module are integrated into the water contact detection arrangement 40, it can power itself during the detection process, enabling it to operate independently. Simultaneously, the water contact detection arrangement 40 can autonomously transmit the detected water contact status signal wirelessly to the control unit 90 of the air treatment device 1 via its integrated wireless communication module.Even when the air treatment device 1 is switched off, the water contact detection arrangement 40 can still independently detect contact with water in the event of a water leak on the outside of the device body 10.

[0139] Furthermore, the wireless communication module can establish a direct connection with the user's mobile phone, allowing information on the water contact status to be transmitted to the user's mobile application. This enables the user to remotely monitor the risk of water leakage in the air treatment device 1 and receive an early warning, thereby improving the timeliness and reliability of water contact detection.

[0140] As in Fig. 8 and Fig.As shown in Figure 9, in some embodiments the water contact detection arrangement 40 further comprises a mounting section 405, whereby the water contact detection arrangement 40 can be attached to both the device body 10 and the target object B via the mounting section 405.

[0141] The mounting section 405 can be arranged on or formed on the housing 403. The mounting section 405 can comprise one of the following parts: a magnetic attraction section, a hook section, a plug-in section, or a clamping section. Accordingly, the device body 10 can also be provided with a mating section that interacts with the mounting section, thereby facilitating the attachment of the mounting section 405 to the device body 10. In particular, the mating section can be a metal plate, a plug slot, etc.

[0142] When the air treatment device 1 is in standby mode, the water contact detection device 40 can be attached to the device body 10 via the mounting section 405, thus preventing the water contact detection device from being lost. When the water contact detection device 40 needs to be put into operation, it can also be attached to the target object B via the mounting section 405.

[0143] For example, the target object B can be the first water tank B1 and the mounting section 405 the hook section. When the air treatment device 1 starts operating, the user can suspend the water contact detection arrangement 40 from the edge or side wall of the first water tank B1 using its hook section. Thus, as the first water tank B1 approaches a nearly full state, the water in the first water tank B1 comes into contact with the exposed first electrode 401 and the second electrode 402 of the water contact detection arrangement 40, thereby triggering the generation of a water contact status signal.

[0144] In some embodiments, the housing 403 is provided with a receiving slot, and the mounting section 405 includes two hooks that are relatively movable relative to the housing 403. When the water contact detection arrangement 40 is required, the hook can be unscrewed from its receiving slot, thus facilitating its suspension on the target object B (e.g., the top of the first water tank B1). When the water contact detection arrangement 40 needs to be positioned within the target area A, for example, when placing the water contact detection arrangement 40 on a floor or table surface, the hook can be unscrewed back into the receiving slot. This facilitates the stable placement of the water contact detection arrangement 40 on the surface of the target area A and prevents it from protruding beyond the surface of the housing 403.Otherwise, such a protrusion would prevent direct contact between the water contact detection arrangement 40 and the target area A. This would hinder the rapid response of the water contact detection arrangement 40 to water contact.

[0145] In some embodiments, the device body 10 may include a storage slot. Because the device body 10 includes the storage slot, the water contact detection arrangement 40 is stored detachably in this storage slot.

[0146] In some embodiments, it is provided that the blower arrangement 30 maintains its current operating state when the water contact detection arrangement 40 outputs the water contact status signal and the heat exchanger 20 stops its operation.

[0147] When the water contact detection device 40 outputs a water contact status signal, users can promptly address the water leak in target area A thanks to the early warning message. The control unit 90 can then activate the blower device 30 to maintain its current operating state and continue functioning. The airflow driven by the blower device 30 promotes the evaporation of moisture within target area A (i.e., on the floor or table surface) and restores dry indoor conditions as quickly as possible.
