Description

Technical Field

[0001] This invention relates to dehumidification technology, and more particularly to a dehumidification water tank structure capable of detecting the water tank position and controlling the pumping time, and a pumping control method thereof. Background Technology

[0002] Dehumidifiers are common indoor dehumidification devices. They absorb moisture from the indoor air, convert it into water, and store it in a water tank, thus reducing the humidity in the air. However, the dehumidifier's water tank needs to be cleaned regularly. But existing dehumidifier water tank structures still have some problems and shortcomings: First, traditional dehumidifiers using reed switch floats for water tank level detection often leave a layer of residual water at the bottom of the tank when it's nearly empty. This water cannot be effectively utilized, yet the system has already determined that dehumidification is complete, leading to water wastage and an inability to accurately determine the actual water volume. Furthermore, the persistent residual water can easily breed bacteria and produce odors. Second, traditional dehumidifiers typically use capacitive touch sensors to detect water level, lacking leak protection. When the tank is lifted, the system cannot immediately determine that the tank has been removed and will not immediately stop dehumidification and drainage. The lack of protection means that the dehumidifier may overflow when the water tank is full or continue dehumidifying with the base exposed, easily wetting the table or floor, posing a safety hazard and causing inconvenience. Furthermore, it lacks instantaneous water lifting and overflow protection. Additionally, current dehumidifiers with water pump drainage functions typically place the water pump inside the casing, making pump replacement and maintenance difficult. For dehumidifiers with water pump drainage, the corresponding water tank uses a complex structure with two floats for high and low water levels, which is more expensive and hinders production and cost control.

[0003] Therefore, there is an urgent need to improve the water tank structure of existing dehumidifiers so that they can protect against leaks and detect the liquid level in the user's water tank in a timely manner. Summary of the Invention

[0004] This invention provides a dehumidifier water tank structure and its pumping control method that can detect the water tank position and control the pumping time. It effectively distinguishes between when the water tank is full and when the water tank is pumped out, accurately prompts the user, and improves the user experience of the dehumidifier. Furthermore, by changing the pumping time and the time when the water tank is full, it automatically controls the pumping time to adapt to the pumping volume under different pumping heads, thus improving the user experience.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows: A dehumidifier water tank structure capable of detecting the position of the water tank and controlling the pumping time includes a water tank, a controller, and a display and alarm device. The water tank is installed on the dehumidifier body, and the controller and the display and alarm device are installed inside the dehumidifier body and electrically connected to the water tank through a control circuit. The display and alarm device is used to display or indicate the liquid level in the water tank. The water tank is equipped with a single vertically sliding float for detecting the liquid level in the tank. The inner wall side of the water tank where it connects with the dehumidification body is provided with a circuit connector for connecting the power supply circuit and the detection circuit between the two. The detection circuit is electrically connected to the controller and the display and alarm devices. The power supply circuit is connected to the water pump installed in the water tank for pumping out wet water. The dehumidification body is also equipped with a water full proximity switch for sensing the liquid level float when the water tank is full. The controller, based on the conductive contact signals from the detection circuit of the water pump and the circuit connector on the dehumidifier body, as well as the signal from the water full proximity switch, is used to distinguish between water tank being pulled out and water tank being full, and to accurately indicate the user's usage status.

[0006] Preferably, the circuit connection includes two connectors for the power supply circuit and two connectors for the detection circuit located on the inner wall side of the water tank. The two connectors for the power supply circuit and the two connectors for the detection circuit are electrically connected to form four sets of parallel circuit plugs. The corresponding dehumidification body is provided with contact sockets that are in contact with the four sets of circuit plugs.

[0007] Preferably, the detection circuit forms a low-voltage circuit for controlling the start and stop of the water pump and detecting the extraction of water from the water tank.

[0008] Preferably, the power supply circuit is the operating power supply for the water pump.

[0009] Inside the water tank, close to the dehumidifier body, there is a limiting groove for the liquid level float to move up and down as the amount of dehumidified water collected.

[0010] The control method for a dehumidification water tank structure capable of detecting the water tank position and controlling the pumping time, as described above, includes the following steps: S1. Power on and run; S2. First, check whether the following conditions are met simultaneously: ① the water tank is full and the proximity switch is open, and ② the detection circuit is open. The water tank is full and the proximity switch is open when the water level float rises after the water tank is full, and the magnetic water tank proximity switch is opened. This state indicates that the water tank is full. The detection circuit is open, which means that the water tank is detached from the dehumidification body. S3. If the judgment is yes, it is considered that the water tank is not in place, which means that the water tank is pulled out of the dehumidification unit. At this time, the dehumidifier will not run, indicating no water tank, no power supply to the water pump component, and the water pump cannot start. This process ends. S4. If conditions ① water full proximity switch is not open and condition ② detection circuit is not open, the judgment is no, the dehumidifier refrigeration system will operate normally, and the water pump will not be powered or run. S5. Then, continuously determine whether condition ① the proximity switch is open when the water is full; S6. If condition ① is not met, it means that the condensate water in the water tank has not reached the designed full water state. Return to step S4 and the dehumidifier refrigeration system continues to operate normally. S7. If condition ① is met, proceed to the next step to determine whether the water pump function should be turned on. S8. If the water pump function is not turned on, the dehumidifier will stop running, the water pump will not be powered and will not run, and the user will be notified that the water tank is full of condensate water. The water tank will be full and the process will end. S9. If the water pump function has already been started, then continue to determine if the detection circuit of condition ③ is normal. S10. If condition ③ is not met, it indicates that the water pump circuit is not working and the water pump function should not be started. At this time, the dehumidifier should stop working and indicate that the water tank is full of condensate; or it indicates a water pump circuit fault and the process will end. S11. When condition ③ is met, the dehumidifier will not report that the water is full and will proceed to the next step of "delay 2S water pump power supply" operation. S12. After executing the "Delay 2S Water Pump Power Supply" operation, determine whether the water pump is starting to pump water for the first time. S13. If so, the pumping will stop after pumping water for T minutes. S14. If this is not the first start, record the time interval between this start and the last pump start, and determine whether the pump start interval meets △T1. S15. If the pump start interval meets △T1, the pump will stop pumping after pumping time T1 min. S16. If the pump start interval does not meet △T1, then continue to determine whether the pump start interval meets △T2. S17. If △T2 is not satisfied, the water pump returns to step S13 and executes according to the initial pumping time T min. S18. If △T2 is satisfied, the pumping time will end after pumping for 2 minutes.

[0011] Furthermore, steps S14 and S18 also include: When the water pump is turned on, the water tank reaches its full capacity when the condensate reaches the full capacity, which satisfies condition ① when the water full proximity switch is turned off. This is the basic condition for the water pump to start working. Since the flow rate of the water pump is different at different pump heads, the pumping time is automatically controlled according to the time interval between each pump start to ensure the pumping volume at different pump heads and reduce the amount of water remaining in the water tank. The relevant time parameters are derived as follows: Time T min is the pumping time to pump the water level in the tank to the lowest level under the reference head of 0m, and it is obtained from the test during development. Time T1 min is the pumping time to pump the water level in the tank to the lowest level under a head of H1 m, which was obtained from tests during development; Time T2 min is the pumping time to pump the water level in the tank to the lowest level under a head of H2 m, which was obtained from tests during development; To further increase the accuracy of fuzzy inference, the range of values ​​for △T is determined by referring to Formula 1 and Formula 2: ------Formula 1 ------Formula 2 △T takes the range of (Ta, Tb). In Formula 1 and Formula 2, L—Pump flow rate at a reference head of 0m; Lx——Pump flow rate at a head of xm; T — the pumping time required for the water pump at a reference head of 0m to pump the water level in the tank to the lowest water level. da — Condensate production rate under dehumidifier case a; db — Condensate production rate under dehumidifier b scenario; Based on the above, determine the values ​​of T1 and △T1 during the development phase; Similarly, the values ​​of T2 and △T2 are determined during the development phase.

[0012] Furthermore, step S12 also includes: The detection circuit uses a weak electrical signal. Because the voltage is low, the arcing energy generated at the moment of connection is weak. However, the water pump power supply circuit has a higher voltage, so theoretically the arcing energy is greater at the moment of connection. Therefore, when the conditions are met, for dehumidifiers with flammable refrigerant, a delayed power supply control mode is used for the water pump to reduce the risk of fire. The beneficial effects of this invention are: In existing technologies, the water pump is usually placed inside the dehumidifier casing, which makes it difficult to replace and maintain the water pump. At the same time, for dehumidifiers with water pump drainage, the water tank often adopts a water tank structure with two floats at high and low water levels. This structure is relatively complex, costly, and not conducive to production and cost control.

[0013] In this invention, the water pump assembly is used as a module and placed separately in the water tank for convenient after-sales maintenance. Meanwhile, for flammable refrigerants, the water pump power supply circuit, due to its high voltage, theoretically has a large arcing energy at the moment of connection. For dehumidifiers containing flammable refrigerants, immediate power supply upon pump connection poses a fire hazard. Therefore, when conditions are met, a software method is used to control the delayed power supply at the contact points. This delayed power supply control mode controls the power supply time difference of the water pump, resolving the fire hazard when the water tank is removed / returned, and improving safety.

[0014] Furthermore, by combining the conductive contacts of the detection circuit between the water pump and the dehumidifier with the signal from the water full proximity switch, and using control methods, the system can distinguish between situations such as a full water tank and a water tank being removed, thus accurately alerting the user and improving the dehumidifier's user experience.

[0015] Furthermore, during the water pumping process, the pumping time is automatically controlled by varying the pumping time and the time it takes for the water to fill, thus adapting to different pumping volumes under different head conditions and improving the user experience.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] A dehumidifying water tank 1 structure capable of detecting the position of the water tank 1 and controlling the pumping time, such as Figures 1 to 5 As shown, the system includes a water tank 1, a controller (not shown), and a display and alarm device (not shown). The water tank 1 is mounted on the dehumidification body 2. The controller and the display and alarm device are installed inside the dehumidification body 2 and are electrically connected to the water tank 1 via a control circuit. The display and alarm device is used to display or indicate the liquid level in the water tank 1. A single sliding float 3 is installed in the water tank 1 to detect the liquid level. A limiting groove 4 is provided inside the water tank 1 near the dehumidification body 2 to allow the float 3 to slide up and down according to the amount of dehumidified water collected. A limiting groove 4 is provided on the inner wall of the joint between the water tank 1 and the dehumidification body 2. There is a circuit connector 5 for connecting the power supply circuit and the detection circuit between the two. The detection circuit is electrically connected to the controller, display and alarm device. The power supply circuit is wired to the water pump (not shown in the figure) installed in the water tank 1 for pumping out dehumidified water. The dehumidification body 2 is also equipped with a water level proximity switch (not shown in the figure) for sensing the liquid level float 3 when the water tank 1 is full. The controller uses the conductive contact signal of the detection circuit of the water pump and the circuit connector 5 on the dehumidification body 2, as well as the signal of the water level proximity switch, to distinguish between the water tank 1 being pumped out and the water tank 1 being full, and to accurately prompt the user on the usage status.

[0021] like Figures 2 to 5 As shown, in this embodiment, the circuit connector 5 includes two connectors 50 for the power supply circuit and two connectors 51 for the detection circuit, located on the inner wall side of the water tank 1. The two connectors 50 for the power supply circuit and the two connectors 51 for the detection circuit are electrically connected to form four sets of parallel circuit plugs. The corresponding dehumidification body 2 is provided with contact sockets 6 that are in contact with the four sets of circuit plugs. Wherein, as... Figure 1As shown, the two plugs in the center of the circuit connector 5 are the two connectors for the detection circuit, and the two connectors on either side of the two connectors for the central detection circuit are the two connectors for the power supply circuit. Furthermore, the detection circuit forms a low-voltage circuit for controlling the start and stop of the water pump and detecting the extraction of water from the water tank 1, while the power supply circuit is the operating power source for the water pump.

[0022] like Figure 1 As shown, a liquid level float 3 is installed in the water tank 1. As the amount of condensate in the water tank 1 increases, the liquid level float 3 will float up. As the liquid level float 3 moves further away, the water full proximity switch signal paired with it on the dehumidifier body 2 will be disconnected, thus determining whether the water tank 1 is full. Simultaneously, as... Figure 1 As shown, the water pump is placed in water tank 1. The top of the pump has four plugs. Two plug contacts form a circuit, and the detection circuit formed by the two middle plugs is configured for low voltage (e.g., 5V). The power supply circuit formed by the two outer plug contacts connects to the pump wiring and serves as the pump's operating power supply, as shown below. Figure 2 As shown, there are four conductive contacts at corresponding positions on the dehumidifier body 2. When the water tank 1 is placed inside the unit, as... Figure 3 When the plug on water tank 1 comes into contact with the conductive contacts, a closed circuit is formed.

[0023] In this embodiment, the water pump assembly is used as a module and placed separately in the water tank 1 for convenient after-sales maintenance. Moreover, by combining the conductive contacts of the detection circuit between the water pump and the dehumidifier with the signal of the water full proximity switch, and in conjunction with subsequent control methods, the system can distinguish between situations such as the water tank 1 being full or the water tank 1 being withdrawn, thereby accurately prompting the user and improving the dehumidifier user experience.

[0024] The control method for the dehumidification water tank 1 structure, which can detect the position of water tank 1 and control the pumping time, is as follows: Figure 1 , Figure 4 and Figure 6 As shown, it includes the following steps: S1. Power on and run; S2. First, check whether the conditions ① water full proximity switch is open and condition ② detection circuit is open are met simultaneously. The water full proximity switch is open when the water level float 3 rises after the water tank 1 is full and the magnetic water full proximity switch is opened. This state indicates that the water tank 1 is full. The detection circuit is open, which means that the water tank 1 is detached from the dehumidification body 2. S3. If the judgment is yes, it is considered that the water tank 1 is not in place, that is, the water tank 1 is pulled out of the dehumidification body 2. At this time, the dehumidifier does not run, and the message "no water tank 1" is displayed. No power is supplied to the water pump assembly, and the water pump cannot start. This process ends. S4. If conditions ① water full proximity switch is not open and condition ② detection circuit is not open, the judgment is no, the dehumidifier refrigeration system will operate normally, and the water pump will not be powered or run. S5. Then, continuously determine whether condition ① the proximity switch is open when the water is full; S6. If condition ① is not met, it means that the condensate water in water tank 1 has not reached the designed full water state. Return to step S4 and the dehumidifier refrigeration system continues to operate normally. S7. If condition ① is met, proceed to the next step to determine whether the water pump function should be turned on. S8. If the water pump function is not turned on, the dehumidifier will stop running, the water pump will not be powered and will not run, and the user will be notified that the condensate in water tank 1 is full. The water tank will be full and the process will end. S9. If the water pump function has already been started, then continue to determine if the detection circuit of condition ③ is normal. S10. If condition ③ is not met, it means that the water pump circuit is not working and the water pump function should not be started. At this time, the dehumidifier should stop working and indicate that the condensate in water tank 1 is full; or it indicates that the water pump circuit is faulty and the process ends. S11. When condition ③ is met, the dehumidifier will not report that the water is full and will proceed to the next step of "delay 2S water pump power supply" operation. S12. After executing the "Delay 2S Water Pump Power Supply" operation, determine whether the water pump is starting to pump water for the first time. S13. If so, the pumping will stop after pumping water for T minutes. S14. If this is not the first start, record the time interval between this start and the last pump start, and determine whether the pump start interval meets △T1. S15. If the pump start interval meets △T1, the pump will stop pumping after pumping time T1 min. S16. If the pump start interval does not meet △T1, then continue to determine whether the pump start interval meets △T2. S17. If △T2 is not satisfied, the water pump returns to step S13 and executes according to the initial pumping time T min. S18. If △T2 is satisfied, the pumping time will end after pumping for 2 minutes.

[0025] In steps S14 and S18, when the water pump is activated, the water tank 1 reaches its full capacity (condition ①, where the water full proximity switch is disconnected) as the basic condition for the water pump to start working. Since the flow rate varies at different pump heads, the pumping time is automatically controlled based on the time interval between each pump start-up to ensure sufficient water volume at different pump heads and minimize residual water in the water tank 1, as described in the above process steps. The relevant time parameters are as follows: Time T min is the pumping time to pump the water level in tank 1 to the lowest level under the reference head of 0m, and it is obtained from the test during development. Time T1 min is the pumping time to pump the water level in tank 1 to the lowest level under a head of H1 m, which is obtained from the test during development. Time T2 min is the pumping time to pump the water level in tank 1 to the lowest level under a head of H2 m, which was obtained from tests during development. To further increase the accuracy of fuzzy inference, the range of values ​​for △T is determined by referring to Formula 1 and Formula 2: ------Formula 1 ------Formula 2 △T takes the range of (Ta, Tb). In Formula 1 and Formula 2, L—Pump flow rate at a reference head of 0m; Lx——Pump flow rate at a head of xm; T — The pumping time for the water pump at the reference head of 0m to pump the water level in water tank 1 to the lowest water level; da——The condensate production rate of the dehumidifier under condition a. The dehumidification capacity under a certain working condition can be tested according to the actual situation. The following example takes the dehumidification capacity under high temperature working condition. db—Condensate production rate of dehumidifier under condition b. The dehumidification capacity under a certain operating condition can be tested according to the actual situation. The following example takes the dehumidification capacity under the nominal operating condition. Based on the above, determine the values ​​of T1 and △T1 during the development phase; For example: A certain dehumidifier has a dehumidification capacity of 0.624 L / h at high temperature and a nominal dehumidification capacity of 0.417 L / h. The measured water pump flow rate of this dehumidifier with a 0-meter head is 229.8 L / h. This water pump takes 0.016 hours to pump water from tank 1 to the minimum water level. Similarly, the measured flow rate of the same dehumidifier with a 1-meter head decreases to 150 L / h. At a 1-meter head, this water pump takes 0.025 hours to pump water from tank 1 to the minimum water level. Substituting this development phase test data into Formula 1 and Formula 2: =2.0 h =3.0 h Therefore, the logical value of △T1 here is 2.0 h < △T1 ≤ 3.0 h. Substituting the data from the development phase above into this logic yields T = 0.016 h; T1 = 0.025 h; ΔT1 is (2h, 3h). Similarly, using the above algorithm, the values ​​of T2 and ΔT2 are determined during the development phase. This allows for automatic control of the pumping time during the pumping process, adapting to different pumping volumes at different head levels by varying the pumping time and the time it takes for the water to fill, thus improving the user experience.

[0026] Furthermore, in step S12, the detection circuit uses a weak electrical signal. Due to the low voltage, the arcing energy generated at the moment of connection is weak. However, the water pump power supply circuit, due to its higher voltage, theoretically generates a larger arcing energy at the moment of connection. Therefore, when the conditions are met, for dehumidifiers containing flammable refrigerant, a delayed power supply control mode is adopted for the water pump to reduce the risk of fire. This is a crucial design point, addressing the fire hazard when the water tank 1 is pulled out / returned, and improving the safety of the dehumidifier.

[0027] In this embodiment, when water tank 1 is not in place, the water pump detection circuit and the water full proximity switch signal corresponding to water tank 1 are disconnected simultaneously. However, when the dehumidifier is in place during normal dehumidification and the water tank is full, the water pump detection circuit of water tank 1 is conductive, and only the water full proximity switch signal is disconnected. Therefore, in the water pumping control method, the signals of conditions ① and ② are used to distinguish between the normal water full situation and the situation of water tank 1 being pumped out, so as to accurately prompt the user and improve the user experience of the dehumidifier.

[0028] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.

This is the basic condition for the water pump to start working. Since the flow rate of the water pump is different at different pump heads, the pumping time is automatically controlled according to the time interval between each pump start to ensure the pumping volume at different pump heads and reduce the amount of water remaining in the water tank. The relevant time parameters are derived as follows: Time T min is the pumping time to pump the water level in the tank to the lowest level under the reference head of 0m, and it is obtained from the test during development. Time T1 min is the pumping time to pump the water level in the tank to the lowest level under a head of H1 m, which was obtained from tests during development; Time T2 min is the pumping time to pump the water level in the tank to the lowest level under a head of H2 m, which was obtained from tests during development; To further increase the accuracy of fuzzy inference, the range of values ​​for △T is determined by referring to Formula 1 and Formula 2: ------Official 1 ------Official 2 △T takes the value of (Ta, Tb) In Formula 1 and Formula 2, L—Pump flow rate at a reference head of 0m; Lx——Pump flow rate at a head of xm; T — the pumping time required for the water pump at a reference head of 0m to pump the water level in the tank to the lowest water level. da — Condensate production rate under dehumidifier case a; db — Condensate production rate under dehumidifier b scenario; Based on the above, determine the values ​​of T1 and △T1 during the development phase; Similarly, the values ​​of T2 and △T2 are determined during the development phase.

8. The control method for a dehumidifying water tank structure capable of detecting the water tank position and controlling the pumping time according to claim 6, characterized in that, Step S12 also includes: The detection circuit uses a weak electrical signal. Because the voltage is low, the arcing energy generated at the moment of connection is weak. However, the water pump power supply circuit has a higher voltage, so theoretically the arcing energy is greater at the moment of connection. Therefore, when the conditions are met, for dehumidifiers with flammable refrigerant, a delayed power supply control mode is used for the water pump to reduce the risk of fire.
