The humidifier also has a drying function. In the standby drying state, the humidifier only needs to run the ultraviolet lamp, the fan and the PTC heating body, and through the heating and ultraviolet sterilization, the water and viruses on the wet curtain are removed; but in the drying state, since the humidifier only starts a part of the load, it is difficult to detect whether the humidifier is faulty in the drying state.

Thus, features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically defined.

[0041] The main working principle of the humidifier detected in the present application is as follows:

[0042] The humidifier comprises a base, a water tank and a wet curtain.

[0043] The water tank is provided with an ultraviolet lamp, a water pump and other types of loads. The ultraviolet lamp can be installed at the bottom of the water tank or other positions in the water tank. In the humidifying state, the water pump pumps water to the wet curtain, and the wet curtain evaporates the water on the wet curtain into water vapor through a heating device or a fan, and blows the water vapor into the air through the fan to achieve the humidifying effect. When the working state of the humidifier is the drying state, the water pump stops working, and only the ultraviolet lamp is turned on to remove bacteria and excess water in the wet curtain until the water in the wet curtain is evaporated. In addition, a male gold finger is installed outside the water tank, and a female gold finger is installed on the base (as shown in Figure 4 When the water tank and the base are connected through the gold fingers, the water pump, the ultraviolet lamp and other loads in the water tank can be powered, and at this time the loads can work normally.

[0044] In the drying state, the fault detection method of the humidifier is implemented, and the flowchart is as shown in Figure 1 The method comprises the following steps:

[0045] A1, obtaining the placement state of the water tank;

[0046] The placement state of the water tank is in the lowered state. The water tank has two states, which are respectively raised and lowered. When the water tank is raised, the male gold finger on the water tank is disconnected from the female gold finger on the base, and the water tank is separated from the base. Since the base is connected to the power supply, when the water tank is raised, the humidifier stops supplying power, and all loads are turned off. When the water tank is lowered, the male gold finger on the water tank is successfully connected to the female gold finger on the base, and at this time the loads on the humidifier are powered. Therefore, when the humidifier is detected, the water tank needs to be in the lowered state.

[0047] A2, obtaining the working state of the humidifier;

[0048] The working state of the humidifier is in the drying state. The humidifier has four states, which are respectively the drying state, the humidifying state, the standby state and the protection state. In the drying state, only the ultraviolet lamp, the heating device and the fan of the humidifier are turned on, and the water pump is in the closed state, so as to realize the drying and sterilization of the wet curtain. In the humidifying state, all components are in the turned-on state, so as to realize the normal humidifying function of the humidifier. In the protection state, all loads are turned off when a special fault occurs. In the standby state, all loads are turned off.

[0049] A3, obtaining the ultraviolet lamp signal and the water pump signal;

[0050] The ultraviolet lamp signal and the water pump signal can be divided into two cases of being turned on and being turned off. When the ultraviolet lamp signal and the water pump signal are turned on, it indicates that the circuit lines corresponding to the ultraviolet lamp and the water pump are in a pass-through state at this time. If the humidifier is in a drying state and a humidifying state at this time, it indicates that the ultraviolet lamp and the water pump are normal at this time. Similarly, if the ultraviolet lamp signal and the water pump signal are turned off, the ultraviolet lamp and the water pump are faulty at this time. In the protection state and the standby state, the situation is opposite to that in the drying state and the humidifying state. When the ultraviolet lamp signal and the water pump signal are turned off, the ultraviolet lamp and the water pump are normal. When the signals are turned on, the ultraviolet lamp and the water pump are faulty.

[0051] For example, the on-off state of the corresponding electric lines of the water pump and the ultraviolet lamp in the humidifier can be collected by an AD voltage or a photosensitive sensor.

[0052] A4. According to the signal state of the ultraviolet lamp signal and the water pump signal, it is judged whether the humidifier is in a fault state.

[0053] When the water tank placement state of the humidifier is a lowering state, and the working state of the humidifier is a drying state, according to the signal state of the ultraviolet lamp signal and the water pump signal, it is judged whether the humidifier is in a fault state.

[0054] A5. When the ultraviolet lamp signal is in an off state, a detection result that the humidifier is faulty in a drying state is output.

[0055] The specific cases are as follows:

[0056] (1) golden finger fault;

[0057] (2) water pump and ultraviolet lamp fault at the same time;

[0058] (3) ultraviolet lamp fault.

[0059] In practical application, the above fault reasons can be fed back to the technical personnel for troubleshooting.

[0060] The preset time length is less than or equal to the time for the water pump to pump the water in the water tank to the wet curtain.

[0061] A7. When the ultraviolet lamp signal is turned on, and the water pump signal is turned on, a detection result that the humidifier is normal in a drying state is output.

[0062] A8. When the ultraviolet lamp signal is turned on, and the water pump signal is turned off, a detection result that the humidifier is faulty in a drying state is output.

[0063] The fault reasons are analyzed as follows:

[0064] In the drying state, if the ultraviolet lamp signal is turned on, it indicates that the ultraviolet lamp is normal, the golden finger is normally connected, and the power supply is normal. At this time, the water pump is started for a preset time, and the water pump signal is detected within the preset time. If the water pump signal is in an off state, it indicates that the water pump is malfunctioning at this time. Therefore, the humidifier is malfunctioning, and the cause of the malfunction is the water pump malfunction.

[0065] From the above embodiment one, the following beneficial effects can be seen:

[0066] In the case that the water tank is in a lowered state and the humidifier is in a drying state, the humidifier is detected by analyzing the ultraviolet lamp signal and the water pump signal. When the ultraviolet lamp signal is turned on and the water pump signal is turned on within the preset time, it indicates that the humidifier is normal. When the ultraviolet lamp signal is turned on and the water pump signal is turned off within the preset time, it indicates that the humidifier is malfunctioning, and the cause of the malfunction is the water pump malfunction. When the ultraviolet lamp signal is turned off and the water pump signal is turned on within the preset time, it indicates that the humidifier is malfunctioning, and the cause of the malfunction is the ultraviolet lamp malfunction. When the ultraviolet lamp signal is turned off and the water pump signal is turned off within the preset time, it indicates that the humidifier is malfunctioning, and the cause of the malfunction is unknown. By only increasing two kinds of signal feedback and controlling the opening time of the water pump, the detection of the humidifier in the drying state is realized, the cost is reduced, and the use of space is reduced.

[0067] In addition to the drying state, the embodiment also provides a method for detecting the humidifier in the humidifying state, and the flow is as shown in Figure 2 .

[0068] In the embodiment, steps B1 to B3 are consistent with steps A1 to A3 of the above embodiment one, and will not be described here.

[0069] B4, according to the signal state of the ultraviolet lamp signal and the water pump signal, whether the humidifier is in a fault state is judged.

[0070] In the case that the water tank of the humidifier is in a lowered state, and the working state of the humidifier is in a humidifying state, whether the humidifier is in a fault state is judged according to the signal state of the ultraviolet lamp signal and the water pump signal.

[0071] B5, if the working state is in a humidifying state, and the water pump signal and the ultraviolet lamp signal are in a turned-on state, a detection result that the humidifier is normal in the humidifying state is output.

[0072] B6, if the working state is in a humidifying state, and at least one of the water pump signal and the ultraviolet lamp signal is in an off state, a detection result that the humidifier is malfunctioning in the humidifying state is output.

[0073] The analysis of the cause of the malfunction shows that:

[0074] In the humidification state, the ultraviolet lamp and the water pump are powered at the same time. When the ultraviolet lamp signal is turned on and the water pump signal is turned off, it indicates that the gold finger is normally connected and the power supply is normal at this time, so the water pump signal is turned off, which indicates that the water pump is faulty, so the humidifier is faulty, and the fault reason is the water pump fault.

[0075] In the humidification state, the ultraviolet lamp and the water pump are powered at the same time. When the ultraviolet lamp signal is turned off and the water pump signal is turned on, when the water pump signal is turned on, it indicates that the gold finger is normally connected and the power supply is normal at this time, so the ultraviolet lamp signal is turned off, which indicates that the ultraviolet lamp is faulty, so the humidifier is faulty, and the fault reason is the ultraviolet lamp fault.

[0076] In the humidification state, the ultraviolet lamp and the water pump are powered at the same time. When the ultraviolet lamp signal is turned off and the water pump signal is turned off, the fault reason is not clear. There are the following situations:

[0077] (1) Gold finger fault;

[0078] (2) Water pump and ultraviolet lamp fault at the same time;

[0079] (3) Both of the above occur.

[0080] In actual application, the above fault reasons can be fed back to the technical personnel for troubleshooting.

[0081] For example, in actual application, the working state of the humidifier can also be a standby state or a protection state, and the application embodiment also provides corresponding judgment logic (not drawn through a flow chart, and specific reference can be made to the above embodiment).

[0082] If the working state is a standby state or a protection state, and the water pump signal and the ultraviolet lamp signal are in an off state, a detection result that the humidifier is normal in the protection state is output;

[0083] If the working state is a standby state or a protection state, and at least one of the water pump signal and the ultraviolet lamp signal is in an on state, a detection result that the humidifier is faulty in the protection state is output.

[0084] The fault reason is analyzed as follows:

[0085] In the standby state or the protection state, all loads of the humidifier are in an off state. When the ultraviolet lamp signal is turned off and the water pump signal is turned on, it indicates that the water pump is faulty, so the humidifier is faulty, and the fault reason is the water pump fault.

[0086] In standby state or protection state, all loads of the humidifier are in off state, when the ultraviolet lamp signal is on and the water pump signal is off, it indicates that the ultraviolet lamp is faulty, and the humidifier is faulty, and the fault reason is the ultraviolet lamp fault.

[0087] In standby state or protection state, all loads of the humidifier are in off state, when the ultraviolet lamp signal is on and the water pump signal is on, the humidifier is faulty, and the fault reason is unknown, please contact the relevant staff to check and determine;

[0088] From the above embodiment two, the following beneficial effects can be seen:

[0089] Through the analysis of the ultraviolet lamp signal and the water pump signal, whether the humidifier is faulty in different states is obtained, in the humidification state, the on signal is normal and the off signal is abnormal; in the protection state and the standby state, the on signal is abnormal and the off signal is normal; when the ultraviolet lamp signal and the water pump signal are normal, the humidifier is normal; when the ultraviolet lamp signal is normal and the water pump signal is abnormal, the humidifier is faulty, and the reason is the water pump fault; when the ultraviolet lamp signal is abnormal and the water pump signal is normal, the humidifier is faulty, and the fault reason is the ultraviolet lamp fault; in this embodiment, the humidifier fault detection in the drying state is realized without increasing the hardware cost, and the scheme is simple and efficient.

[0090] In addition to the detection of the humidifier fault in various working states of the humidifier, the humidifier of the present application also has the following problems: when the water tank is in the lifted state, if the humidifier fault detection is started, the ultraviolet lamp signal and the water pump signal must be off, which may misjudge that the humidifier is faulty; when the humidifier is in the humidification state, if the ultraviolet lamp signal is on and the water pump signal is off at this time, it indicates that the water pump is faulty, and there is no continuous water flow supply on the wet curtain, and the continued work of the heating device may cause safety hazards. Therefore, in special cases, the present application also needs to protect the switching of the working state and the water tank placement state of the humidifier. The present application embodiment provides a corresponding solution, as shown in the flowchart Figure 3 , which comprises:

[0091] C1, judging the water tank placement state of the humidifier.

[0092] C2, if the humidifier placement state is the lifted state at this time, then the step of driving the water tank placement state to be switched to the lowered state is executed.

[0093] C3, if the humidifier placement state is the lowered state at this time, the working state of the humidifier is obtained.

[0094] C4, when the working state of the humidifier is the humidification state, the states of the ultraviolet lamp signal and the water pump signal are obtained.

[0095] C5, when the ultraviolet lamp signal is in the on state and the water pump signal is in the off state, the current working state of the humidifier is switched to the protection state.

[0096] The following beneficial effects can be seen from Example Three:

[0097] When the placement state of the water tank is determined to be the lifting state, the placement state of the water tank is driven to be the lowering state, so as to reduce the failure of detecting the fault of the humidifier when the water tank is in the lifting state; when the placement state of the water tank is the lowering state, the humidifier can formally work; when the working state of the humidifier is the humidifying state and the ultraviolet lamp signal is on and the water pump signal is off, the working state of the humidifier is changed to the protection state, so as to reduce the possible safety hazard.
