[0031] In order to more comprehensively understand the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration purposes only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, numerous details are provided to give a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices may be shown in a simplified manner to simplify the drawings.

[0032] In some embodiments, a dehumidifier is provided, which includes a dehumidification system and a water tank. The dehumidification system is used to adjust the humidity of the indoor air. The dehumidification system includes a compressor, a condenser, and an evaporator. The water tank is used to store the condensed water generated during the dehumidification process.

[0033] Optionally, the dehumidifier further includes a magnetic sensor switch disposed on the water tank. The magnetic sensor switch is used to monitor whether the water in the water tank is full. If the water level in the water tank reaches the preset water level line, the float of the magnetic sensor switch floats under the action of buoyancy. At this time, the magnetic sensor switch is in an open state and sends an open signal to prompt the user that the water in the current water tank is full and needs to be emptied. When the water level in the water tank does not reach the preset water level line, the magnetic sensor switch remains in a normally closed state, that is, remains in a connected state, and feeds back a connected signal.

[0034] Optionally, the dehumidifier further includes a weight detection member disposed at the bottom of the water tank. The weight detection member is used to detect the weight of the water tank. The water level condition in the water tank can also be determined through the weight detection member. By presetting the first weight threshold when the water in the water tank is full in the memory of the dehumidifier. During use, the weight of the water tank is detected by the weight detection member and compared with the first weight threshold to determine whether the water volume in the water tank reaches the full state.

[0035] In this embodiment, by setting the weight detection member, the feedback signal of the magnetic sensor switch can be confirmed. In this way, the accuracy of determining that the water in the water tank is full is improved, the false alarm rate is reduced, and the user experience is enhanced.

[0036] Optionally, the dehumidifier further includes a water level detection member for detecting the water level in the water tank. The water level detected by the water level detection member is compared with the preset water level line to determine whether the current water level in the water tank reaches the full state. According to the comparison result that the preset water level line is reached, a water full alarm reminder message is sent to remind the user to empty the water in the water tank in time.

[0037] In some embodiments, the dehumidifier further includes a processor and a memory storing program instructions. The processor is configured to execute the control method of the dehumidifier when executing the program instructions.

[0038] In some embodiments, in combination with Figure 1As shown, a control method for a dehumidifier is provided, including:

[0039] S102, the processor obtains the feedback signal of the magnetic sensor switch.

[0040] Detect the weight of the water tank through a weight detection component.

[0041] S104, the processor obtains the weight of the water tank.

[0042] S106, the processor determines whether the feedback signal is a valid signal according to the weight and the first weight threshold.

[0043] S108, based on the feedback signal being a valid signal, the processor controls the operation of the dehumidifier according to the feedback signal.

[0044] S110, based on the feedback signal being an invalid signal, a fault prompt message is sent.

[0045] For the control method of the dehumidifier provided by the present disclosure, after receiving the feedback signal sent by the magnetic sensor switch, the weight of the water tank is obtained. The weight of the water tank is compared with the first weight threshold. According to the comparison result, it is determined whether the feedback signal sent by the magnetic sensor switch is accurate. The present disclosure proofreads the feedback signal of the magnetic sensor switch through the weight of the water tank, and controls the operation of the dehumidifier according to the proofreading result. Compared with the related art, in the method of water full alarm according to the feedback signal of the magnetic sensor switch. The control method of the dehumidifier provided by the present disclosure can improve the accuracy of water full alarm.

[0046] Wherein, the first weight threshold corresponds to the weight value of the water tank when the water level in the water tank reaches the preset water level line. The preset water level line is the water level line when the water in the water tank is full and needs to be emptied.

[0047] It can be understood that the height of the preset water level line is less than the depth of the water tank. To avoid the water in the water tank being too full and easy to overflow, and it is not convenient to take out, improving the user experience.

[0048] Optionally, the step of determining whether the feedback signal is a valid signal according to the weight and the first weight threshold includes: based on the feedback signal being a disconnection signal, determining whether the weight is greater than or equal to the first weight threshold; based on the weight being greater than or equal to the first weight threshold, determining that the feedback signal is a valid signal; based on the weight being less than the first weight threshold, controlling the dehumidifier to continue running for a first preset duration, and detecting the signal state of the magnetic sensor switch again; according to the signal state, determining whether the magnetic sensor switch is abnormal.

[0049] In this embodiment, the feedback signal is a disconnection signal, and the preset information fed back by the disconnection signal is that the water level in the water tank has reached the preset water level line, that is, the water full state. If this signal is a valid signal, a prompt message for reminding the user that the water is full and needs to be emptied needs to be sent.

[0050] Therefore, by comparing the current weight of the water tank with the first weight threshold, it is determined whether the water level in the water tank has reached the full water state. When the weight is greater than or equal to the first weight threshold, it indicates that the water level in the water tank has reached the full water state, that is, the feedback signal of the magnetic sensor switch is a valid signal. According to the valid signal, the dehumidifier is controlled to send out a full water pouring reminder message to remind the user to pour water in time, and the dehumidification system is controlled to stop running to avoid overflow of the water in the water tank. When the weight is less than the first weight threshold, it indicates that the current weight has not reached the weight value corresponding to the full water state. By further controlling the dehumidifier to run for the first preset duration, and then according to the signal state of the magnetic sensor switch detected again, it is determined whether the magnetic sensor switch is abnormal, so as to be able to give a fault reminder and repair in time, improve the user's usage status, and improve the accuracy of signal feedback.

[0051] Optionally, the step of determining whether the magnetic sensor switch is abnormal according to the signal state includes: judging whether the weight is greater than or equal to the second weight threshold; based on the weight being greater than or equal to the second weight threshold and the signal state being a disconnection signal, it is determined that the magnetic sensor switch is normal and the feedback signal is a valid signal; based on the weight being greater than or equal to the second weight threshold and the signal state being a connection signal, it is determined that the magnetic sensor switch is abnormal and the feedback signal is an invalid signal; based on the weight being less than the second weight threshold, it is determined that the magnetic sensor switch is abnormal and the feedback signal is an invalid signal; wherein, the second weight threshold is less than the first weight threshold.

[0052] In this embodiment, by setting the second weight threshold, the weight threshold range is divided into three types, which are greater than or equal to the first weight threshold, less than the first weight threshold and greater than or equal to the second weight threshold, and less than the second weight threshold. In this way, it is possible to predict the possible faulty components of the dehumidifier according to the different ranges of the current weight of the water tank, and improve the efficiency of troubleshooting.

[0053] Specifically, when the weight is greater than or equal to the second weight threshold and less than the first weight threshold, if the detected signal state is a disconnection signal, it is determined that the magnetic sensor switch is normal and the feedback signal is a valid signal. In this way, according to the disconnection signal, the dehumidifier is controlled to send out a full water alarm reminder and the dehumidifier is controlled to stop. If the detected signal state is a connection signal, it means that the magnetic sensor switch has given a false alarm, the feedback signal is ignored, and the dehumidifier is controlled to continue running. By detecting the weight of the water tank to proofread the feedback signal of the magnetic sensor switch, the accuracy of the dehumidifier control is improved, the probability of false alarm is reduced, and the user's usage experience is improved.

[0054] When the weight is less than the second weight threshold, that is, the weight corresponding to the current water volume in the water tank differs significantly from the first weight threshold in the full water state, it indicates that the feedback signal of the magnetic sensor switch is an invalid signal. There is an abnormality in the magnetic sensor switch, and the dehumidifier is controlled to give a fault alarm reminder for timely troubleshooting.

[0055] Optionally, the value range of the second weight threshold is 75% to 85% of the first weight threshold. Specifically, the value of the second weight threshold is 75%, 80% or 85% of the first weight threshold.

[0056] Optionally, the value range of the first preset duration is 4 minutes to 6 minutes.

[0057] In some embodiments, as shown in Figure 2 a control method for a dehumidifier is provided, including:

[0058] S202, the processor obtains the feedback signal of the magnetic sensor switch, and the feedback signal is an open signal.

[0059] S204, the processor obtains the weight M of the water tank.

[0060] The weight of the water tank is detected by a weight detection component.

[0061] S206, the processor compares the weight M of the water tank with the first weight threshold M S and the second weight threshold M L for comparison.

[0062] S208, based on M≥M S , the processor determines that the feedback signal is a valid signal and sends a water full alarm prompt message.

[0063] S210. Based on M L ≤M<M S , the processor controls the dehumidifier to continue running for the first preset duration and detects the signal state of the magnetic sensor switch again.

[0064] S212, the feedback signal detected again by the processor is an open signal, and a water full alarm prompt message is issued.

[0065] S214, the feedback signal detected again by the processor is a connected signal, it is determined that the magnetic sensor switch gives a false alarm, and the dehumidifier is controlled to continue running.

[0066] S216, based on M<M L , the processor controls the dehumidifier to continue running for the first preset duration and detects the signal state of the magnetic sensor switch again.

[0067] S218, the feedback signal detected again by the processor is an open signal, and the operating state of the compressor is detected.

[0068] S220. Based on the compressor being in the working state, the processor determines that the float of the magnetic sensor switch is stuck, issues a fault reminder, and resets the magnetic sensor switch.

[0069] S222. Based on the compressor being in the shutdown state, the processor determines that the magnetic sensor switch is abnormal and issues a fault reminder.

[0070] S224. The feedback signal detected again by the processor is a connected signal. It determines that the magnetic sensor switch has given a false alarm and controls the dehumidifier to continue running.

[0071] In this embodiment, for the process of proofreading the feedback signal of the magnetic sensor switch being a disconnected signal, the current weight of the water tank is detected by a weight detection component. The weight detection component includes a weight sensor. Compare the current weight M distribution of the water tank with M S 、M L for comparison.

[0072] M≥M S , indicating that the water level in the water tank has reached the full water state, that is, the feedback signal is a valid signal. According to the valid signal, control the dehumidifier to issue a reminder message for full water and pouring, to remind the user to pour water in time, and control the dehumidification system to stop running to avoid water overflow in the water tank.

[0073] M L ≤M<M S , control the dehumidifier to continue running for a first preset duration and detect the signal state of the magnetic sensor switch again. If the feedback signal detected again is a disconnected signal, it means the magnetic sensor switch is normal. According to the disconnected signal, control the dehumidifier to issue a full water alarm reminder and control the dehumidifier to shut down. If the feedback signal detected again is a connected signal, it means the magnetic sensor switch has given a false alarm, ignore the feedback signal, and control the dehumidifier to continue running.

[0074] Based on M<M L , control the dehumidifier to continue running for a first preset duration and detect the signal state of the magnetic sensor switch again. If the feedback signal detected again is a disconnected signal, further detect the operating state of the compressor to determine the fault problem. When the compressor is in the working state, determine that the float of the magnetic sensor switch is stuck, issue a fault reminder, and reset the magnetic sensor switch. When the compressor is in the shutdown state, determine that the signal of the magnetic sensor switch is abnormal, issue a fault reminder, and perform maintenance or replacement. If the feedback signal detected again is a connected signal, determine that the magnetic sensor switch has given a false alarm and control the dehumidifier to continue running.

[0075] Through the embodiments of the present disclosure, the feedback signal of the magnetic sensor switch is calibrated by the weight of the water tank and the first weight threshold and the second weight threshold, improving the accuracy of the dehumidifier control and reducing the probability of false alarms. Moreover, while calibrating the feedback signal, the fault problems of the dehumidifier are determined and a fault reminder is given, improving the maintenance efficiency and enhancing the user experience.

[0076] Optionally, the step of determining whether the feedback signal is a valid signal according to the weight and the first weight threshold includes: when the feedback signal is a connected signal, determining whether the weight is greater than or equal to the first weight threshold; if the weight is greater than or equal to the first weight threshold, determining that the feedback signal is an invalid signal; if the weight is less than the first weight threshold, determining that the feedback signal is a valid signal.

[0077] In this embodiment, the feedback signal is a connected signal, and the preset information fed back by the connected signal is that the water level in the water tank is lower than the preset water level line corresponding to the full water state. That is, the water in the water tank corresponding to the connected signal has not reached the full water state. During actual use, the magnetic sensor switch is in a normally closed state, that is, in a connected state. By detecting the connected signal of the magnetic sensor switch and combining the weight of the water tank, the state of the magnetic sensor switch can be determined.

[0078] Specifically, when the detected weight of the water tank is greater than or equal to the first weight threshold, it indicates that the water level in the water tank has reached the preset water level line, that is, the full water state, and the magnetic sensor switch should send a disconnection signal. Therefore, the connected signal obtained at this time is an invalid signal. That is, there is an abnormality in the magnetic sensor switch, a fault reminder is issued, and the dehumidifier is controlled to perform a fault prediction logic. When the weight is less than the first weight threshold, it means that the water level in the water tank has not reached the full water state, which matches the connected signal. It is determined that the feedback signal is a valid signal.

[0079] In some embodiments, in combination with Figure 3 as shown, a control method for a dehumidifier is provided, including:

[0080] S302, the processor obtains the feedback signal of the magnetic sensor switch, and the feedback signal is a connected signal.

[0081] S304, the processor obtains the cumulative operation duration T of the compressor after the water tank completes the last water pouring.

[0082] S306, the processor compares the cumulative operation duration T with T s for comparison.

[0083] S308, based on T < T s , the processor determines that the feedback signal is a valid signal and controls the dehumidifier to continue running.

[0084] T sis the second preset duration, and the second preset duration is the cumulative operating duration of the compressor corresponding to the water tank from the emptied state to the full state.

[0085] S310, based on T≥T s , the processor obtains the weight M of the water tank.

[0086] S312, the processor compares the weight M of the water tank with the first weight threshold M S .

[0087] S314, based on M≥M S , the processor obtains the operating state of the compressor.

[0088] S316, based on the compressor being in the working state, the processor determines that the float is stuck, controls the magnetic sensor switch to reset, and issues a fault prompt message and a water full alarm reminder.

[0089] S318, based on the compressor being in the shutdown state, the processor determines that the feedback signal is an invalid signal, and issues a fault prompt message and a water full alarm reminder.

[0090] S320, based on M<M S , the processor compares M with the third weight threshold M T .

[0091] S322, based on M≤M T , the processor issues a dehumidification system fault reminder message.

[0092] S324, based on M>M T , the processor controls the dehumidifier to continue running.

[0093] In this embodiment, the process of proofreading the feedback signal of the magnetic sensor switch as a connected signal is as follows: Before proofreading the feedback signal according to the weight of the water tank, the cumulative operating duration T of the compressor since the last time the water tank was emptied until the current moment is also obtained. By comparing T with T s , the current water level of the water tank is determined, and then it is determined whether the current water level corresponds to the connected signal. T s is the second preset duration, and the second preset duration is the cumulative operating duration of the compressor corresponding to the water tank from the emptied state to the full state.

[0094] When T<T s , it means that the cumulative operating duration of the compressor has not reached the second preset duration, that is, the feedback signal is a valid signal, and the dehumidifier is controlled to continue running.

[0095] When T≥T s, it indicates that the cumulative operation duration of the compressor has reached the second preset duration, and the water level in the water tank is at the full state. Thus, the feedback connection signal is an invalid signal, and there may be an abnormality in the magnetic sensor switch. Further, obtain the weight M of the water tank. Compare the weight M with the first weight threshold M S to determine whether the magnetic sensor switch is abnormal.

[0096] When M ≥ M S , it indicates that the water level in the water tank has reached the full state, that is, the connection signal is an invalid signal. Further, obtain the operating state of the compressor and analyze the fault problem. If the compressor is in the working state, it is determined that the float is stuck, control the magnetic sensor switch to be reset, and issue a fault prompt message and a full water alarm reminder. If the compressor is in the shutdown state, it is determined that the signal of the magnetic sensor switch is invalid, issue a fault prompt message and a full water alarm reminder, and the magnetic sensor switch needs to be repaired.

[0097] When M < M S , it indicates that the water level in the water tank has not reached the full state. Further compare M with the third weight threshold M T . If M ≤ M T , it indicates that the water level in the water tank does not match the operation duration of the compressor, and there is a possibility of a fault in the dehumidification system. Therefore, a dehumidification system fault reminder message is issued for repair. When M > M T , it indicates that the water level in the water tank matches the operation duration of the compressor, and control the dehumidifier to continue running.

[0098] Optionally, the value range of the third weight threshold is 65% to 75% of the first weight threshold. Specifically, the value of the third weight threshold is 65%, 70% or 75% of the first weight threshold.

[0099] Through the embodiments of the present disclosure, for the case where the feedback signal of the detected magnetic sensor switch is a connection signal, the accuracy of the connection signal is verified by combining the cumulative operation duration of the compressor and the weight of the water tank. At the same time, whether there are faults in the magnetic sensor switch and the dehumidification system is analyzed, and a fault reminder message is issued in time to remind the user to process it in time, improving the user experience.

[0100] In some embodiments, before issuing the dehumidification system fault reminder message, the control method further includes: performing a fault judgment on the dehumidification system. By performing a fault judgment on the dehumidification system, a suggested direction for troubleshooting can be given, thereby improving the repair efficiency.

[0101] Optionally, as shown in Figure 4 , the method for performing a fault judgment on the dehumidification system includes:

[0102] S402, the processor obtains the coil temperature T of the evaporator p and the indoor ambient temperature T N ;

[0103] S404, the processor compares T p with k×T N .

[0104] Wherein, k is a preset coefficient less than 1 and greater than zero. The value range of k is between 0.7 and 0.8.

[0105] S406, based on T p <k×T N , the processor determines that there is a refrigerant leak in the dehumidification system and sends a prompt message of refrigerant leak.

[0106] S408, based on T p ≥k×T N , the processor obtains the inlet pressure of the compressor;

[0107] S410, based on the inlet pressure being within the first preset range, the processor determines that there is a refrigerant leak in the dehumidification system and sends a prompt message of refrigerant leak.

[0108] The first preset range is plus or minus 0.0005% of the rated pressure at the inlet of the compressor.

[0109] S412, based on the inlet pressure being within the second preset range, the processor determines that the compressor is faulty and sends a compressor fault reminder.

[0110] The second preset range is from 0 to 0.0005 N.

[0111] In this embodiment, by combining the coil temperature of the evaporator and the indoor ambient temperature, it is determined whether there is a fault in the dehumidification system. According to the determination result, the user is timely informed to improve the user experience.

[0112] Specifically, the two situations where the fault problems of the dehumidification system occur relatively frequently are: refrigerant leak and compressor fault.

[0113] Considering that if there is refrigerant, the coil temperature of the evaporator will increase. Therefore, by comparing the coil temperature with the indoor ambient temperature, it is determined whether there is a refrigerant leak. When T p <k×T N , it is determined that there is a refrigerant leak in the dehumidification system and a prompt message of refrigerant leak is sent. k is a preset coefficient less than 1 and greater than zero. The value range of k is between 0.7 and 0.8. When T p ≥k×T N, that is, the coil temperature is relatively close to the indoor ambient temperature, or has reached the indoor ambient temperature. In this case, there is a serious refrigerant leakage, or the compressor has a fault. Further, the pressure at the inlet of the compressor is detected. By setting a pressure sensor in the intake pipe of the compressor to detect the pressure at the inlet. If there is a refrigerant leakage, there is pressure at the inlet. If the compressor fails to operate, the inlet pressure is almost zero. Therefore, when the inlet pressure is within the first preset range, that is, close to the rated pressure of the inlet, it is determined that there is a serious refrigerant leakage in the dehumidification system, and a prompt message of refrigerant leakage is sent. When the inlet pressure is within the second preset range, that is, the inlet pressure is almost zero, it is determined that the compressor has a fault, and a compressor fault reminder is sent. Through the embodiments of the present disclosure, the analysis of the faults of the dehumidifier is realized, thereby improving the fault repair efficiency and enhancing the user experience.

[0114] Optionally, the feedback signal is a disconnection signal. Based on the condition that the feedback signal is a valid signal, the steps of controlling the dehumidifier to operate according to the feedback signal include: controlling the compressor to operate at a first preset power for a third preset duration; and obtaining the water level information in the water tank; according to the water level information, controlling the dehumidifier to give a water full alarm reminder in a preset manner, and controlling the operating state of the compressor.

[0115] In this embodiment, the feedback signal is a disconnection signal, and the preset information fed back by the disconnection signal is that the water level in the water tank has reached the preset water level line, and the preset water level line is lower than the depth of the water tank, so that a water full early warning can be given to the user before the water tank is completely filled with water. If this signal is a valid signal, the dehumidifier is controlled to operate according to the disconnection signal.

[0116] Specifically, the steps of controlling the dehumidifier to operate include: controlling the compressor to reduce the operating power to the first preset power and continuously operate for the third preset duration. And obtain the real-time water level information in the water tank. According to the water level information in the water tank, give a water full alarm reminder and control the operating state of the compressor in a preset manner corresponding to the water level information. In this way, a pre-alarm for the water tank being full is realized, leaving time for the user to pour water, and enhancing the user experience.

[0117] Optionally, the first preset power is less than the operating power during the normal dehumidification process of the compressor. Specifically, the value range of the first preset power is 60% to 70% of the operating power during the normal dehumidification process. The value range of the third preset duration is 4 minutes to 6 minutes.

[0118] In some embodiments, as shown in Figure 5 , a control method for a dehumidifier is provided, including:

[0119] S502, the processor obtains the feedback signal of the magnetic sensor switch, and the feedback signal is a disconnection signal.

[0120] The weight of the water tank is detected by a weight detection component.

[0121] S504, the processor obtains the weight of the water tank.

[0122] S506, the processor determines that the feedback signal is a valid signal according to the weight and the first weight threshold.

[0123] S508, the processor controls the compressor to operate at a first preset power for a third preset duration.

[0124] S510, the processor obtains the water level information D in the water tank;

[0125] S512, the processor compares the water level information D with the first preset water level D min , the second preset water level D max for comparison.

[0126] S514, based on D < D min , the processor controls the water full alarm signal to be reset and controls the compressor to continue operating.

[0127] S516, based on D min ≤ D < D max , the processor controls the dehumidifier to send a water full alarm signal in a first preset manner.

[0128] S518, the processor controls the compressor to operate at a second preset power.

[0129] S520, based on D > D max , the processor controls the dehumidifier to send a water full alarm reminder in a second preset manner.

[0130] S522, the processor controls the compressor to stop.

[0131] Wherein, D min < D max , and the first preset power is greater than the second preset power.

[0132] In this embodiment, the feedback signal of the magnetic sensitive switch is a disconnection signal, and the disconnection signal is calibrated by the weight of the water tank. When the calibration result is a valid signal, the dehumidifier is controlled through the water level information in the water tank to pre - alarm the user and reserve time for the user to handle the water tank. During the pre - alarm process, the dehumidifier is kept running to improve the user experience. If the user still does not handle the water tank until it is full, the compressor is then controlled to stop, improving the intelligence of the dehumidifier control.

[0133] Specifically, by setting a first preset water level and a second preset water level, the first preset water level is lower than the second preset water level. When the water level in the water tank reaches the first preset water level, the water full pre-alarm is started.

[0134] Specifically, when D < D min , control the reset of the water full alarm signal, that is, cancel the alarm signal, and control the compressor to continue running. When D min ≤ D < D max , start the alarm, and control the dehumidifier to send a water full alarm signal in a first preset manner. Also, control the compressor to run at a second preset power. When D > D max , it indicates that the water level in the water tank has reached the full state, control the dehumidifier to send a water full alarm reminder in a second preset manner. And, control the compressor to stop, to avoid the water in the water tank from overflowing.

[0135] Optionally, in the first preset manner, the alarm beeps every 3 to 5 seconds for 3 to 5 seconds. The second preset manner is to beep every 3 to 5 seconds for 8 to 10 seconds. The specific interval duration and beep duration can be specifically set according to requirements and will not be elaborated here.

[0136] Optionally, set the preset water level line of the water tank as D, and D is less than the depth H of the water tank. The value range of the first preset water level D min is 80% D to 90% D. The value range of the second preset water level D max is 95% D to 105% D.

[0137] Optionally, the second preset power is the minimum power for the compressor to run.
