[0026] The following will be combined with the embodiments and the drawings in the embodiments to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiment is only a sub-embodiment of a unit of the present invention, rather than an embodiment of the whole unit. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] In addition, in the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may be implemented without these specific details. In other cases, known structures and devices are embodied in a schematic manner to simplify the accompanying drawings.

[0028] The humidifier device installed on the ceiling can be provided with a water inlet valve at the water inlet to control the water inlet amount. However, when the water inlet valve is damaged, it will cause water leakage to the ceiling. In order to reduce the water leakage, the prior art adds another water inlet valve on this basis. However, since the humidifier device is installed on the ceiling and two or more water valves are provided, the detection difficulty will increase. The maintenance personnel need to remove the water valve to determine which water inlet valve is damaged and causes the water leakage.

[0029] To address the deficiencies of the above-mentioned prior art, an embodiment of the present disclosure provides a humidifying device. The humidifying device may include a humidifying unit, a water valve, a humidifying water level detection unit, and a control unit. The humidifying unit is formed with an air inlet and an air outlet that allow gas to circulate, and a water inlet that allows humidifying liquid to enter. The water valve may include a main water valve and a humidifying water valve. Driven by an external power device, the humidifying liquid enters the humidifying unit in sequence through the main water valve, the humidifying water valve, and the water inlet. The humidifying water level detection unit may be used to detect the water level in the humidifying unit. The control unit may be used to control the main water valve and the humidifying water valve to open alternately, and based on the detection results of the detection unit, determine whether there is an abnormality in the main water valve and / or the humidifying water valve, and control the humidifying device to enter a humidification mode that uses the humidifying unit to humidify the gas.

[0030] According to the embodiment of the present disclosure, by setting up a control unit, the humidification water valve and the main water valve can be controlled to be alternately opened or closed, so as to alternately detect the humidification water valve and the main water valve, so as to determine whether there is an abnormality in any water valve of the humidification water valve and the main water valve, thereby achieving the purpose of facilitating the detection and maintenance of the water valve.

[0031] First embodiment

[0032] The humidifying device according to the embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0033] Figure 1 The working principle diagram of the humidifying device according to the first embodiment of the present disclosure is schematically shown.

[0034] like Figure 1 As shown, the present invention provides a humidifying device. The humidifying device may include a housing. The housing may include a main housing 11. The humidifying device also includes a humidifying part 2, a water valve 3, a humidifying water level detection part 4, a heating part 5 and a control part (not shown in the figure) arranged in the housing.

[0035] According to an embodiment of the present invention, the main housing 11 can be configured as a box-like structure, such as a rectangular parallelepiped or a cube. The main housing 11 can have a top surface, a bottom surface, and a side surface. The side surface can include a first wall surface and a second wall surface. In other optional embodiments, the main housing 11 can also be configured into other shapes, such as a cylindrical shape, a prismatic shape, etc. Further, the air inlet and the air outlet of the humidifying unit 2 can be formed on the main housing 11. External air can enter the humidifying unit 2 through the air inlet.

[0036] According to an embodiment of the present invention, the air inlet can be arranged on one side of the housing, specifically, the air inlet is located on the first wall of the main housing 11. In other optional embodiments, the air inlet can also be arranged at other positions of the housing, such as the top surface or the bottom surface, etc., and its setting position can be adjusted according to actual needs. The gas in the humidifying unit 2 can flow out to the external space through the air outlet.

[0037] According to an embodiment of the present invention, the air outlet may be disposed on a side surface of the main housing 11, specifically, the air outlet may be located on a second wall surface of the main housing 11 opposite to the first wall surface. In other optional embodiments, the air outlet may also be disposed at other positions of the housing, such as the bottom surface or the top surface, and its location may be adjusted according to actual needs and the relative position of the air inlet.

[0038] According to an embodiment of the present invention, the humidifying unit 2 can break the liquid in the humidifying unit 2 into liquid in an atomized state. After the gas enters the humidifying unit 2 from the air inlet, the gas can carry the atomized liquid and be discharged from the air outlet to achieve the purpose of humidifying the external space. The flow path of the gas can be as follows: Figure 1As shown by the dotted arrow in FIG. In this embodiment, the liquid may be a humidifying liquid, and the humidifying liquid may be water.

[0039] According to an embodiment of the present invention, the humidifying part 2 may include a water basin 21, a motor 23 and a crushing part 22. The water basin 21 may be arranged in the main housing 11. The water basin 21 may be formed with a water inlet and a drain port for allowing the humidifying liquid to flow out. The crushing part 22 may be arranged in the water basin 21. The bottom of the crushing part 22 may be formed with an opening, and the opening may be arranged above the drain port. The crushing part 22 may be a turntable or a disc. The motor 23 may be connected to the crushing part 22 through a rotating shaft. When the control unit controls the motor 23 to drive the crushing part 22 to rotate, the humidifying liquid in the water basin 21 enters the crushing part 22 through the opening, thereby preventing the humidifying liquid from being discharged from the drain port. After the humidifying liquid enters the crushing part 22, the crushing part 22 may drive the large particles of the humidifying liquid to collide with the wall of the water basin 21, and then crush the large particles of the humidifying liquid into water mist particles, thereby humidifying the gas flowing in the humidifying part 2. The humidification degree can be adjusted by adjusting the rotation speed of the motor 23. The motor 23 may be a motor 23 capable of achieving stepless adjustment of the rotation speed, such as a DC motor. The motor 23 may also be a type that can only adjust the rotation speed according to a fixed gear, such as an AC motor. In other optional embodiments, other types of motors may also be used. Further, when the control unit controls the crushing unit 22 to stop rotating, the humidifying liquid may be discharged from the drain port.

[0040] According to an embodiment of the present invention, the water inlet of the humidifying part 2 can be connected to the water inlet end of the humidifying device through a water pipe. The water inlet end of the humidifying device can be connected to a water source outside the humidifying device through a water pipe to obtain the humidifying liquid outside the humidifying device. The water source outside the humidifying device can be the most basic and easily available humidifying liquid. A water valve 3 can be provided on the water pipe, and the water valve 3 can be used to make the liquid in the water pipe flow or stop and control its flow rate.

[0041] According to an embodiment of the present invention, the water valve 3 may include a main water valve 31 and a humidifying water valve 32. The main water valve 31 and the humidifying water valve 32 may be connected in series. The main water valve 31 may be arranged upstream of the humidifying water valve 32. The main water valve 31 may be arranged on a side of the humidifying device close to the water inlet end. The humidifying water valve 32 may be arranged between the main water valve 31 and the water inlet of the humidifying part 2. When the main water valve 31 is closed, the humidifying liquid cannot flow from the water inlet end to the humidifying water valve 32. The humidifying water valve 32 is located downstream of the main water valve 31. When the main water valve 31 and the humidifying water valve 32 are both opened, water flows into the humidifying part 2 via the main water valve 31 and the humidifying water valve 32 in sequence. When the humidifying water valve 32 is closed, the liquid cannot enter the humidifying part 2.

[0042] According to an embodiment of the present invention, the heating unit 5 can be arranged in the main housing 11 and located between the humidifying unit 2 and the air inlet of the humidifying device. The heating unit 5 can be used to heat the air before entering the humidifying unit 2. When the heating unit 5 is turned on, the gas enters the humidifying unit 2 after being heated by the heating unit 5, so as to accelerate the humidification efficiency, increase the temperature of the humidified air, and improve the comfort of the human body. The heating unit 5 can be a PTC (Positive Temperature Coefficient) heater or the like for heating the gas structure.

[0043] According to an embodiment of the present invention, the humidification water level detection unit 4 can be used to detect the water level in the humidification unit 2. The humidification water level detection unit 4 may include a first detector 41 and a second detector 42. The first detector 41 may be set at a first position of the humidification unit 2. The first position may be characterized as a low water level of the humidification device. The second detector 42 may be set at a second position of the humidification unit 2. The second position may be characterized as a high water level of the humidification device. The second water level is higher than the first water level, that is, the second water level is set above the first water level. In this embodiment, the first water level is a thirsty water level, that is, a low water level. The second water level is a full water level, that is, a high water level.

[0044] According to the embodiment of the present disclosure, the control unit can be used to control the main water valve 31 and the humidification water valve 32 to open alternately, and based on the detection result of the detection unit, determine whether the main water valve 31 and / or the humidification water valve 32 are abnormal, and control the humidification device to enter the humidification mode of using the humidification unit 2 to break the humidification liquid to humidify the gas. By setting the control unit, the humidification water valve 32 and the main water valve 31 can be controlled to open or close alternately, so as to alternately detect the humidification water valve 32 and the main water valve 31, so as to determine whether any of the water valves 3 of the humidification water valve 32 and the main water valve 31 is abnormal, and the purpose of facilitating the detection and maintenance of the water valve 3 can be achieved.

[0045] According to the embodiment of the present disclosure, the main water valve 31 and the humidification water valve 32 are controlled to open alternately, and based on the detection result of the detection unit, it is determined whether there is an abnormality in the main water valve 31 and / or the humidification water valve 32, which may include: after the humidification liquid in the humidification device is discharged, the main water valve 31 is controlled to open, the humidification water valve 32 is closed, and the power device runs for a period of T1. When the humidification water level detection unit 4 detects that the humidification liquid has reached a predetermined position, it is determined that the humidification water valve 32 is closed abnormally.

[0046] According to the embodiment of the present disclosure, the main water valve 31 and the humidification water valve 32 are controlled to open alternately, and based on the detection result of the detection unit, it is determined whether there is an abnormality in the main water valve 31 and / or the humidification water valve 32. It can also include: after controlling the humidification liquid in the humidification unit 2 to be discharged, the humidification water valve 32 is controlled to open, the main water valve 31 is closed, and the power unit is operated for a period of T2. When the humidification water level detection unit 4 detects that the humidification liquid has reached a predetermined position, it is determined that the main water valve 31 is closed abnormally.

[0047] According to the embodiment of the present disclosure, the predetermined position can be set according to demand, and the predetermined position can be the first position or the second position. The T1 period can be characterized as the time required for the humidifying liquid in the humidifying section 2 to rise from the bottom of the humidifying liquid to the predetermined position when the main water valve 31 is fully opened and the humidifying water valve 32 is opened at any angle. The T2 period can be characterized as the time required for the humidifying liquid in the humidifying section 2 to rise from the bottom of the humidifying liquid to the predetermined position when the humidifying water valve 32 is fully opened and the main water valve 31 is opened at any angle. The T1 period and the T2 period can be the same or different. For example, after the humidifying liquid in the humidifying device is discharged, the main water valve 31 is controlled to open, the humidifying water valve 32 is closed, and the power device runs for 5 minutes, that is, T1 is 5 minutes. When the humidifying water level detection unit 4 detects that the humidifying liquid has reached the first position, it is determined that the humidifying water valve 32 is closed abnormally, that is, the predetermined position can be the first position. For example, after controlling the humidifying liquid in the humidifying part 2 to be discharged, the humidifying water valve 32 is controlled to be opened, the main water valve 31 is controlled to be closed, and the power unit runs for 5 minutes, that is, T2 is 5 minutes. When the humidifying water level detection part 4 detects that the humidifying liquid has reached the second position, it is determined that the main water valve 31 is abnormally closed, that is, the predetermined position can be the second position.

[0048] According to an embodiment of the present disclosure, the control unit controls the humidifying device to enter the humidification mode, which may include repeatedly performing the following operations until a predetermined end condition is met: controlling the water valve 3 to open, the power device to run, so that the liquid enters the humidifying unit 2, and controlling the crushing unit 22 to rotate to humidify the gas. When the second detector 42 detects that the liquid has reached the second position, the control unit controls the water valve 3 to close to prevent the liquid from continuing to enter the humidifying unit 2. After the water valve 3 is closed, the humidifying unit 2 continues to humidify the gas. When the first detector 41 detects that the liquid has dropped back to the first position, the water valve is controlled to open, the crushing unit 22 is rotated, and the power device is operated, so that the liquid rises from the first position to the second position, and then the liquid is discharged. By re-injecting liquid into the humidifying unit 2, the residual liquid in the humidifying unit 2 can be diluted, thereby reducing residues and less scale. The purpose of reducing scale can be achieved by repeating the operation.

[0049] According to an embodiment of the present disclosure, the liquid may be a humidifying liquid. The water valve 3 may be a main water valve 31 and a humidifying water valve 32. The end condition may be that the external space has been humidified to a predetermined humidity. The predetermined humidity may be set by the user according to demand.

[0050] In other embodiments, after the liquid drops from the second position back to the first position, the remaining liquid is directly discharged from the drain port.

[0051] According to an embodiment of the present disclosure, the control unit can also be used to control the humidifier to enter the cleaning mode. Controlling the humidifier to enter the cleaning mode may include: controlling the water valve 3 to open, the power device to run, and controlling the crushing part 22 to rotate to enter the water injection sub-mode. When the second detector 42 detects that the humidifying liquid reaches the second position, the control unit controls the water valve 3 to close and controls the crushing part 22 to stop rotating to roughly discharge the liquid in the humidifying part 2. After roughly discharging the liquid in the humidifying part 2, the crushing part 22 is controlled to rotate again to enter the drying sub-mode for discharging the residual liquid in the humidifying part 2.

[0052] Furthermore, in the drying sub-mode, the control unit can control the main water valve 31 and / or the humidification water valve 32 to open alternately, and based on the detection result of the detection unit, determine whether there is an abnormality in the main water valve 31 and / or the humidification water valve 32, so that while achieving drying, the operation status of the water valve 3 can be determined to avoid damage to the water valve 3 and cause the ceiling to be soaked. Compared with detection in the humidification mode, the humidification time can be saved, thereby not affecting the normal operation of the humidification device and improving the working efficiency of the humidification device.

[0053] According to the embodiment of the present disclosure, in the humidification mode, the heating part 5 can be turned on. In the water injection sub-mode, the heating part 5 can be turned off. In the drying sub-mode, the speed of the motor 23 can be adjusted to the maximum speed, and the heating part 5 can be turned on again to improve the drying efficiency, thereby effectively preventing the generation of mold.

[0054] According to the embodiment of the present disclosure, the control unit controls the main water valve 31 and the humidification water valve 32 to open. After the external power device runs for a period of time T3, and the humidification water level detection unit 4 detects that the humidification liquid has not reached the predetermined position, it is determined that the main water valve 31 and / or the humidification water valve 32 are abnormally opened. The predetermined position can be the first position and / or the second position. For example, in the water injection sub-mode, under normal operation, after the humidification water valve 32 and the main water valve 31 are opened, after the T3 period, for example, T3 is 5 minutes, the humidification water level detection unit 4 should detect that the humidification liquid has reached the first position. After time T5, for example, T5 is 10 minutes, the humidification water level detection unit 4 should detect that the humidification liquid has reached the second position. In the case of abnormal opening of the main water valve 31 and / or the humidification water valve 32, after the humidification water valve 32 and the main water valve 31 are opened, after the T3 period, for example, T3 is 5 minutes, the humidification water level detection unit 4 cannot detect that the humidification liquid has reached the first position. After time T5, for example, T5 is 10 minutes, the humidification water level detection unit 4 cannot detect that the humidification liquid has reached the second position. T3 can be expressed as the time required for the humidification liquid to reach the first position from the bottom of the humidification unit 2 when both the humidification water valve 32 and the main water valve 31 are open. T5 can be expressed as the time required for the humidification liquid to reach the second position from the bottom of the humidification unit 2 when both the humidification water valve 32 and the main water valve 31 are open. T3 and T5 can be set as required. T3 can also be expressed as the time required for the humidification liquid to reach the first position from the bottom of the humidification unit 2 when both the humidification water valve 32 and the main water valve 31 are opened at any angle. T5 can also be expressed as the time required for the humidification liquid to reach the second position from the bottom of the humidification unit 2 when both the humidification water valve 32 and the main water valve 31 are opened at any angle. T5 can also be expressed as the time required for the humidification liquid to reach the second position from the bottom of the humidification unit 2 when both the humidification water valve 32 and the main water valve 31 are opened at any angle. By setting T3 and T5, it can be determined whether the humidification water valve 32 and the main water valve 31 are fully opened or fully closed.

[0055] According to the embodiment of the present disclosure, the control unit controls the main water valve 31 and the humidification water valve 32 to be opened. After the external power device runs for a period of time T3, and the humidification water level detection unit 4 detects that the humidification liquid has not reached the predetermined position for N consecutive times, it is determined that the main water valve 31 and / or the humidification water valve 32 are abnormally opened. The predetermined position includes the first position and / or the second position. In order to avoid misjudgment, after the external power device runs for a period of time T3, the humidification liquid can be detected once every period of time. When the number of detections reaches the preset number of times, it can be determined that the main water valve 31 and / or the humidification water valve 32 are abnormally opened, thereby avoiding misjudgment due to water shortage and other reasons. After the external power device runs for a period of time T3, when it is detected for the first time that the humidification liquid has not reached the predetermined position, the humidification device can be controlled to enter the sleep mode. When it is determined that the main water valve 31 and / or the humidification water valve 32 are abnormally opened, the humidification device can be controlled to shut down. The preset number of times can be set as needed, for example, it can be set to 3 times, and each interval can be 25 minutes. The same method can be used to determine whether the main water valve 31 and / or the humidifying water valve 32 are opened normally during the process of adding the humidifying liquid to the second position, which will not be described in detail here.

[0056] According to an embodiment of the present disclosure, in the cleaning mode, after the second detector 42 detects that the humidifying liquid has reached the second position, the control unit controls the water valve 3 to close and controls the crushing unit 22 to stop rotating for a period of T4, and the humidifying water level detection unit 4 detects that the liquid has been in the second position, it is determined that the main water valve 31 and / or the humidifying water valve 32 are abnormally closed. T4 can be 3 hours. T4 can be expressed as the time required for the liquid in the humidifying unit 2 to be significantly consumed. It should be noted that the drain outlet of the humidifying device is small and the drainage speed is slow, that is, when the main water valve 31 and / or the humidifying water valve 32 are open, the drainage speed of the humidifying device is less than or equal to the liquid inlet speed of the humidifying device.

[0057] In the above process, when it is determined that the main water valve 31 and / or the humidification water valve 32 are abnormally opened, or when it is determined that the main water valve 31 and / or the humidification water valve 32 are abnormally closed, the main water valve 31 and the humidification water valve 32 can be closed to control the humidification device to shut down.

[0058] According to the embodiment of the present disclosure, when it is determined that the water injection sub-mode operates normally and when the second detector 42 detects that the humidifying liquid reaches the second position, the drying sub-mode is entered.

[0059] Second embodiment

[0060] The same structures as those of the first embodiment will not be described in detail, and only the differences are described below.

[0061] Figure 2 The working principle diagram of the humidifying device according to the second embodiment of the present disclosure is schematically shown.

[0062] According to an embodiment of the present invention, the humidifying device may further include a liquid storage unit 6, an electrolysis unit 7 and an electrolysis supply unit 8. The housing 1 may further include a sub-housing 12. The humidifying unit 2 may be arranged in the main housing 11, and the liquid storage unit 6 and the electrolysis unit 7 may be arranged in the sub-housing 12. The liquid storage unit 6 may store a salt solution. The salt solution in the liquid storage unit 6 may be a raw material for preparing a disinfectant. For example, the raw material of the disinfectant may be a sodium chloride solution with a certain concentration, specifically, an unsaturated sodium chloride solution. The electrolysis unit 7 may be connected to the liquid storage unit 6, the main water valve 31 and the humidifying unit 2, respectively. After the salt solution and the humidifying liquid from the main water valve 31 are mixed in the electrolysis unit 7, they are electrolyzed by the electrolysis unit 7 to obtain an electrolyte. After the electrolyte enters the humidifying unit 2, it humidifies the gas together with the humidifying liquid in the humidifying unit 2. The electrolysis supply unit 8 may be arranged between the electrolysis unit 7 and the humidifying unit 2, and may be used to transport the electrolyte generated in the electrolysis unit 7 to the humidifying unit 2.

[0063] According to an embodiment of the present invention, in the humidification mode, the gas can enter the humidification unit 2 from the air inlet, and the humidification unit 2 breaks the liquid in the humidification unit 2 into atomized liquid. The gas can carry the atomized liquid and be discharged from the air outlet to achieve the purpose of humidifying the external space. The flow path of the gas can be as follows: Figure 2 In this embodiment, the liquid may be a mixture of a humidifying liquid and an electrolyte, and the humidifying liquid may be water. The electrolyte may be a disinfectant, and the purpose of disinfecting the gas flowing through can be achieved.

[0064] According to an embodiment of the present invention, the electrolysis unit 7 may include an electrode having an anode and an electrode having a cathode. The electrode may be immersed in the liquid in the electrolysis unit 7 to electrolyze the liquid in the electrolysis unit 7 to generate electrolyzed water.

[0065] According to an embodiment of the present invention, the water pipe may include a main pipe and a branch pipe. The water inlet end of the humidifying device may be arranged on the shell wall of the auxiliary shell 12. The water pipe may include a main pipe and a branch pipe. The main pipe may be connected to the water inlet end to obtain a water source outside the humidifying device.

[0066] According to an embodiment of the present invention, the end of the main pipe may be a tee, branching out two branch pipes. The diameter of the main pipe is greater than the diameter of the branch pipe. The branch pipe may include a humidification branch pipe connecting the water inlet of the humidification unit 2 to the main pipe and an electrolysis branch pipe connecting the electrolysis unit 7 to the main pipe. The humidification branch pipe and the electrolysis branch pipe may be connected in parallel. The power device may provide humidification liquid to the humidification unit 2 through the main pipe and the humidification branch pipe. The power device may provide humidification liquid to the electrolysis unit 7 through the main pipe and the electrolysis branch pipe. The humidification liquid may be water.

[0067] According to an embodiment of the present invention, the water valve 3 may further include an electrolytic water valve 33. The electrolytic water valve 33 may be disposed between the electrolysis unit 7 and the main water valve 31 and connected in parallel with the humidification water valve 32. The electrolytic water valve 33 may be used to control the flow rate of the humidification liquid entering the electrolysis unit 7.

[0068] Furthermore, the electrolysis water valve 33 can be arranged on the electrolysis branch pipe. The humidification branch pipe is provided with a humidification water valve 32 , which can control the flow rate of water entering the humidification part 2 .

[0069] According to an embodiment of the present invention, the humidifying device may further include a liquid storage supply unit 9. The liquid storage supply unit 9 may be disposed between the liquid storage unit 6 and the electrolysis unit 7, and may be used to transport the salt solution in the liquid storage unit 6 to the electrolysis unit 7.

[0070] Further, the preparation of the disinfectant can be carried out in the auxiliary shell 12. Among them, the liquid storage part 6 transports the sodium chloride solution stored in the liquid storage part 6 to the electrolysis part 7 according to a given amount through the liquid storage supply part 9. At the same time, the electrolysis water valve 33 opens a certain opening, and the humidifying liquid supplied from the main pipe is discharged to the electrolysis part 7 through the electrolysis water valve 33. In the electrolysis part 7, the sodium chloride solution is mixed with the humidifying liquid, and the liquid after the humidifying liquid and the sodium chloride solution are mixed is electrolyzed through the anode and the cathode discharge. Under the action of electrolysis, the sodium chloride solution generates hydrogen, chlorine and sodium hydroxide solution, and the chlorine is dissolved in the sodium hydroxide solution and reacts chemically with the sodium hydroxide to generate sodium hypochlorite, forming a sodium hypochlorite solution, that is, forming a disinfectant. After the electrolysis is completed, the electrolysis supply part 8 is started, and the electrolysis water is transported to the humidification part 2 through the electrolysis water supply pipe to humidify the gas. The liquid in the humidification part 2 may include a humidifying liquid and an electrolyte.

[0071] According to an embodiment of the present invention, the humidifying device may further include an electrolysis water level detection unit (not shown in the figure). The electrolysis water level detection unit may be used to detect the water level in the electrolysis unit 7 .

[0072] According to an embodiment of the present invention, after the cleaning mode starts, the control unit first determines whether the humidifier has an electrolysis unit 7. When it is determined that the humidifier has an electrolysis unit 7, a cleaning sub-mode for cleaning the electrolysis unit 7 is first executed, and the water injection mode is entered after the cleaning sub-mode is completed.

[0073] According to an embodiment of the present invention, the control unit controls the humidification device to perform the cleaning sub-mode, which may include: the control unit controls the main water valve 31 and the electrolytic water valve 33 to be opened, the power device to operate, and the electrolytic supply unit 8 to be closed, so as to add the humidifying liquid to the third position of the electrolytic unit 7. After the humidifying liquid is added to the third position, the main water valve 31 may be controlled to be opened, the electrolytic water valve 33 may be controlled to be closed, and the electrolytic supply unit 8 may be controlled to operate, so as to discharge the humidifying liquid to the humidifying unit 2.

[0074] In other embodiments, when the cleaning sub-mode is started, the electrolysis supply unit 8 may be controlled to operate first to drain the liquid in the electrolysis unit 7. The drained liquid may flow out from the drain port in the humidification unit 2. After draining the liquid in the electrolysis unit 7, the electrolysis unit is cleaned.

[0075] According to an embodiment of the present invention, after the control unit controls the main water valve 31 and the electrolysis water valve 33 to be opened and the power device runs for a period of T6, for example, T6 is 150 seconds. When the electrolysis water level detection unit detects that the humidifying liquid of the electrolysis unit 7 is not at the third position, the control unit can determine that the water valve 3 is opened abnormally. The third position can be represented as the full water level of the electrolysis unit 7. T6 can be represented as the time required for the liquid to rise from the bottom of the electrolysis unit 7 to the third position.

[0076] According to an embodiment of the present invention, when the liquid in the electrolysis unit 7 is in the third position, the control unit controls the main water valve 31 to open and the electrolysis water valve 33 to close, and the electrolysis supply unit 8 runs for a period of T7, for example, T7 is 450 seconds. When the electrolysis water level detection unit detects that the water level of the electrolysis unit 7 is always in the third position, the control unit can determine that the electrolysis water valve 33 is abnormally closed. T7 can be expressed as the time required for the liquid in the electrolysis unit 7 to be significantly consumed. In the cleaning sub-mode, it is detected whether the electrolysis water valve 33 is abnormally closed, that is, whether the electrolysis water valve 33 is damaged. Compared with the detection in the humidification mode, it can not take up the humidification time, thereby not affecting the normal operation of the humidification device, and improving the working efficiency of the humidification device.

[0077] In the above process, when the control unit determines that the water valve is abnormally opened, the humidification device reports an error. When the control unit determines that the electrolytic water valve 33 is abnormally closed, the main water valve 31 is closed and the humidification device stops running.

[0078] When the control unit determines that the electrolytic water valve 33 is normal, the liquid will be discharged into the humidifying unit 2, and the liquid will be discharged from the humidifying device through the cleaning mode.

[0079] According to the embodiment of the present disclosure, after the cleaning sub-mode is finished, the liquid in the electrolysis part 7 is discharged to the humidification part 2, and then the water injection sub-mode and the drying sub-mode described in the first embodiment are performed again.

[0080] Specifically, in the water injection sub-mode, the humidification water valve 32 can be controlled to open, the power device can be operated, and the crushing part 22 can be controlled to rotate. When the second detector 42 detects that the liquid in the humidifying part 2 reaches the second position, the control part controls all the water valves 3 to close and controls the crushing part 22 to stop rotating, so as to roughly discharge the liquid in the humidifying part 2. After the liquid in the humidifying part 2 is roughly discharged, the crushing part 22 is controlled to rotate again to enter the drying sub-mode for discharging the residual liquid in the humidifying part 2.

[0081] In summary, the present embodiment has been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the humidification device of the present invention.
