Description

Technical Field

[0001] The present disclosure relates to the technical field of humidifiers, and in particular to a humidifying device and a control method thereof. Background Art

[0002] In the relevant humidification device, when the humidification task is completed or the liquid level drops to the thirsty water level, the liquid in the humidification water pan will be discharged into the drain pan. When the detection unit in the drain pan detects that the liquid in the drain pan has reached the low water level, the liquid in the drain pan will be discharged. However, since the liquid corresponding to the thirsty water level in the humidification water pan is less than the liquid corresponding to the low water level in the drain pan, when the liquid in the humidification water pan drops to the thirsty water level and the liquid is drained to the drain pan, the liquid level in the drain pan may not reach the low water level and the drain pan cannot drain the liquid. As a result, a certain amount of liquid will remain in the drain pan. If it is not discharged in time, the drain pan and its components may become moldy. Summary of the invention

[0037] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the embodiments and the drawings in the embodiments. Obviously, the described embodiments are only embodiments of a unit of the present disclosure, rather than embodiments of the entire unit. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0038] 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.

[0039] In the relevant humidification device, since the liquid corresponding to the thirsty water level in the humidification water pan is less than the liquid corresponding to the low water level in the drain pan, when the liquid in the humidification water pan drops to the thirsty water level and is drained to the drain pan, the liquid level in the drain pan may not reach the low water level and the drain pan cannot drain the liquid. As a result, a certain amount of liquid will remain in the drain pan. If it is not drained in time, the drain pan and its components may become moldy.

[0040] In order to solve the above-mentioned deficiencies of the prior art, the present disclosure provides a humidifying device and a control method thereof. The humidifying device in the present disclosure is described in detail below in conjunction with the accompanying drawings.

[0041] First embodiment

[0042] Figure 1 The working principle diagram of the humidifying device according to the first embodiment of the present disclosure is schematically shown.

[0043] like Figure 1 As shown, in this embodiment, the humidifying device may include a humidifying part 1, a drain part 2 and a controller 3. The humidifying part 1 may include a humidifying water tray 11 and a humidifying unit 12. The humidifying water tray 11 may be formed with an air inlet and an air outlet that allow gas to circulate. The humidifying unit 12 may be located in the humidifying water tray 11, and the humidifying unit 12 may be used to humidify the gas. The drain part 2 may be used to discharge the liquid in the humidifying water tray 11 to the outside of the humidifying device. The controller 3 may be used to control the drain part 2 to discharge the liquid after detecting that the humidifying unit 12 stops running for a predetermined period of time.

[0044] According to the embodiment of the present disclosure, by controlling the drainage part 2 to discharge the liquid after detecting that the humidifying unit 12 stops running for a predetermined period of time, the liquid in the humidifying device can be discharged in time, thereby avoiding the phenomenon of moldy parts in the humidifying device due to water accumulation in the humidifying device.

[0045] According to the embodiment of the present disclosure, the controller 3 can also be used to continue to supply humidifying liquid to the humidifying water tray 11 when it is detected that the liquid in the humidifying water tray 11 drops to the thirsty water level, until the liquid in the humidifying water tray 11 rises to the full water level, and then control the drain part 2 to drain the liquid. By adding the liquid in the humidifying water tray 11 to the full water level and then draining the liquid, that is, diluting the liquid in the humidifying water tray 11, it is possible to avoid excessive scale concentration in the humidifying water tray 11.

[0046] According to an embodiment of the present disclosure, the humidifying device may further include a counter. The counter may count the number of times the liquid in the humidifying water tray 11 rises to the full water level. The controller 3 may also be configured to, when the count value of the counter is a predetermined value and it is detected that the liquid in the humidifying water tray 11 drops to the thirsty water level, continue to supply humidifying liquid to the humidifying water tray 11 until the liquid in the humidifying water tray 11 rises to the full water level, and then control the drain 2 to drain the liquid.

[0047] Considering that it is a waste of resources to drain the liquid after the liquid in the humidification water tray 11 is filled to the full water level each time, by setting a counter, it is possible to control the limited number of times to drain the liquid after the liquid is filled to the full water level, thereby achieving the purpose of saving resources. The predetermined value can be set according to demand. For example, the predetermined value may include 2, 3, and 4. In this embodiment, the predetermined value may be set to 2, that is, the controller 3 drains the liquid after the liquid in the humidification water tray 11 is filled to the full water level every time.

[0048] Second embodiment

[0049] The same structures as those of the first embodiment will not be described in detail, and only the differences are described below.

[0050] Figure 2 The working principle diagram of the humidifying device according to the second embodiment of the present disclosure is schematically shown. Figure 3 A cross-sectional view of a humidifying device according to a second embodiment of the present disclosure is schematically shown.

[0051] like Figure 2 and Figure 3 As shown, in this embodiment, the humidifying device may further include a drain pan 4. The drain pan 4 may be used to accommodate liquid drained from the humidifying water pan 11. The drain portion 2 may be disposed in the drain pan 4, and the drain portion 2 may be used to drain the liquid in the drain pan 4.

[0052] According to the embodiment of the present disclosure, when the humidifying unit 12 stops operating, the liquid in the humidifying water tray 11 can be drained into the drain tray 4 .

[0053] According to an embodiment of the present disclosure, the humidifying unit 12 may include a humidifying rotor 121, a crushing wall 122, and a driver 123. An external water supply portion may be used to provide humidifying liquid to the humidifying water tray 11. The humidifying liquid may be a liquid used for humidification, for example, the humidifying liquid may be water. The humidifying water tray 11 may also be formed with a drain 111. The liquid in the humidifying water tray 11 may be discharged through the drain 111. A recessed area 112 may be formed at the bottom of the humidifying water tray 11. The liquid in the humidifying water tray 11 may be gathered in the recessed area 112 based on the slope of the humidifying water tray 11. The humidifying rotor 121 may be disposed in the humidifying water tray 11 and extend into the recessed area 112. The drain 111 of the humidifying water tray 11 may be disposed at the bottom of the humidifying water tray 11, i.e., in the recessed area 112. There may be a gap between the bottom of the humidifying rotor 121 and the bottom of the humidifying water tray 11. The bottom of the humidifying rotor 121 may be formed with an opening. The opening may be arranged above the drain port 111. The driver 123 may drive the humidifying rotor 121 to rotate. When the humidifying rotor 121 rotates, the liquid in the humidifying water tray 11 may enter the humidifying rotor 121 through the opening of the humidifying rotor 121 and be broken by the humidifying rotor 121, thereby humidifying the gas. After the liquid is broken inside the humidifying rotor 121, it splashes to the broken wall 122 from the outlet of the humidifying rotor 121, and is further broken by the broken wall 122. The drain pan 4 may be located below the drain port 111, and when the humidifying rotor 121 stops rotating, the liquid in the humidifying water tray 11 may flow into the drain pan 4 from the drain port 111. When the humidifying rotor 121 rotates, due to the suction force of the humidifying rotor 121, there may be a gap between the liquid surface and the drain port 111, that is, when the humidifying rotor 121 rotates, there is very little or even no liquid flowing into the drain pan 4. The drain part 2 may be arranged in the drain pan 4. The drain part 2 may be a water pump. The drain part 2 may be used to drain the liquid in the drain pan 4. The controller 3 may be used to control the drain part 2 to drain the liquid in the drain pan 4 after detecting that the humidifying rotor 121 stops rotating for a predetermined time. The predetermined time may be set as required. The predetermined time may be less than or equal to the time required for the liquid to flow from the humidifying water pan 11 to the drain pan 4 to reach the low water level. For example, in this embodiment, the predetermined time may be less than or equal to 30 seconds, 1 minute, 1.2 minutes, or 1.5 minutes.

[0054] Furthermore, the predetermined time length may be greater than or equal to the time length required for the liquid to flow from the humidifying water pan 11 to the drain pan 4 and reach the bottom of the drain portion. The so-called reaching the bottom of the drain portion means reaching the water absorption hole of the drain portion, and the drain portion can work normally to drain water. For example, in this embodiment, the predetermined time length may be greater than or equal to 10 seconds. In this embodiment, the predetermined time length may be equal to 20 seconds.

[0055] According to the embodiment of the present disclosure, by providing a controller 3 and a drain portion 2, the drain portion 2 can be controlled to drain the liquid in the drain pan 4 after detecting that the humidifying rotor 121 stops rotating for a predetermined period of time, thereby allowing the liquid in the drain pan 4 to be drained even when the liquid in the drain pan 4 has not reached a low water level, thereby preventing the drain pan 4 and its components from getting moldy due to water accumulation in the drain pan 4.

[0056] Since the drain portion 2 is disposed in the drain pan 4, in order to ensure that the drain portion 2 can drain, there is a certain distance between the drain portion 2 and the bottom of the drain pan 4. Therefore, even after the drain portion 2 drains, there will still be residual water at the bottom of the drain pan 4. After a part of the residual water evaporates naturally, the scale concentration in the drain pan 4 will increase. When the drain pan 4 is filled with liquid next time, it will mix with the residual liquid, so that the scale concentration in the liquid will increase when the liquid is drained next time. When the scale concentration reaches a certain level, the drain portion 2 or the water pipe may be blocked when draining.

[0057] Therefore, according to the embodiment of the present disclosure, the controller 3 can also be used to continue to supply humidifying liquid to the humidifying water pan 11 when it is detected that the liquid in the humidifying water pan 11 drops to the thirsty water level, until the liquid in the humidifying water pan 11 rises to the full water level, and then control the humidifying rotor 121 to stop rotating to drain the liquid in the humidifying water pan 11 from the drain port 111 to the drain pan 4. After the liquid in the humidifying water pan 11 is filled to the full water level, the liquid in the humidifying water pan 11 is drained to the drain pan 4, that is, the liquid discharged to the drain pan 4 is diluted, so that the scale concentration in the drain pan 4 can be prevented from being too high.

[0058] According to the embodiment of the present disclosure, after all the liquid in the humidifying water pan 11 that has reached the full water level is drained into the drain pan 4, all the liquid in the drain pan 4 can be drained. After all the liquid in the humidifying water pan 11 is drained into the drain pan 4, the liquid in the drain pan 4 will be diluted, so that the scale in the drain pan 4 can be reduced.

[0059] According to the embodiment of the present disclosure, the controller 3 can also be used to continue to supply humidifying liquid to the humidifying water tray 11 when the count value of the counter is a predetermined value and it is detected that the liquid in the humidifying water tray 11 drops to the thirsty water level, until the liquid in the humidifying water tray 11 rises to the full water level, and then control the humidifying rotor 121 to stop rotating so as to drain the liquid in the humidifying water tray 11 from the drain outlet 111 to the drain tray 4.

[0060] According to the embodiment of the present disclosure, the controller 3 can also be used to control the drain part 2 to drain the liquid in the drain pan 11 when it is detected that the liquid in the drain pan 11 is at a low water level. That is, when it is detected that the liquid in the drain pan 11 is at a low water level or when it is detected that the humidifying unit 12 stops running for a predetermined period of time, the drain part 2 can be controlled to drain the liquid.

[0061] According to an embodiment of the present disclosure, the humidifying device may further include a disinfection unit 7. The disinfection unit 7 may be used to provide disinfectant to the humidifying unit 1. When the disinfection unit 7 provides disinfectant to the humidifying unit 1, it may be indicated that the humidifying device enters a disinfection mode. The disinfectant may be mixed with the humidifying liquid in the humidifying unit 1 and broken up by the humidifying rotor 121, so that the humidified gas has a disinfection function.

[0062] According to the embodiment of the present disclosure, the humidifying device may further include an anti-mildew part 6. The anti-mildew part 6 may be disposed in the drain pan 4 to further prevent the drain pan 4 from becoming moldy. By providing the controller 3, the drain part 2 may be controlled to discharge the liquid in the drain pan 4 after detecting that the humidifying rotor 121 stops rotating for a predetermined period of time, so that the liquid in the drain pan 4 may be discharged even if the liquid in the drain pan 4 does not reach the low water level, thereby preventing the anti-mildew part 6 from being immersed in the liquid for a long time, thereby improving the service life of the anti-mildew module.

[0063] According to an embodiment of the present disclosure, the humidifying device may further include at least three detection parts 5. The three detection parts 5 may be respectively arranged at the full liquid level of the humidifying water tray 11, the thirsty water level of the humidifying water tray 11, and the low water level of the drain tray 4. The detection part 5 may be a water level gauge. The three detection parts 5 may include a first detection part, a second detection part, and a third detection part. The first detection part may be arranged at the full liquid level of the humidifying water tray 11 to detect whether the liquid in the humidifying water tray 11 has reached the full liquid level. The first detection part may be connected to a counter so that the counter counts the number of times the liquid in the humidifying water tray 11 rises to the full water level. The second detection part may be arranged at the thirsty water level of the humidifying water tray 11 to detect whether the liquid in the humidifying water tray 11 has reached the thirsty water level. The third detection part may be arranged at the low water level of the drain tray 4 to detect whether the liquid in the drain tray 4 has reached the low water level.

[0064] The control method in the embodiment of the present disclosure is described in detail below with reference to the accompanying drawings.

[0065] Figure 4 The flowchart schematically shows a control method of a humidifying device according to the first embodiment of the present disclosure.

[0066] like Figure 4 As shown, in this embodiment, the control method may include repeatedly executing the following steps S110 to S130.

[0067] In step S110 , humidifying liquid is supplied to the humidifying water tray 11 , and the humidifying unit 12 is driven to operate so as to humidify the gas flowing through the humidifying portion 1 .

[0068] In step S120 , when it is detected that the liquid in the humidification water tray 11 drops to the thirst level, the humidification unit 12 is controlled to stop operating.

[0069] In step S130, after detecting that the humidifying unit 12 stops operating for a predetermined period of time, the drainage part 2 is controlled to operate.

[0070] According to the embodiment of the present disclosure, by controlling the drainage part 2 to discharge the liquid after detecting that the humidifying unit 12 stops running for a predetermined period of time, the liquid in the humidifying device can be discharged in time, thereby avoiding the mold of the components in the humidifying device caused by water accumulation in the humidifying device.

[0071] According to the embodiment of the present disclosure, steps S110 to S130 may be repeatedly performed until the external space is humidified to a predetermined humidity. The predetermined humidity may be set by the user according to needs.

[0072] According to an embodiment of the present disclosure, step S140 is further included before step S120.

[0073] In step S140, when it is detected that the liquid in the humidifying water pan 11 rises to the full water level, the supply of humidifying liquid to the humidifying water pan 11 is stopped, and the humidifying unit 12 continues to operate to continuously humidify the gas. Since the humidifying speed of the humidifying device is lower than the water inlet speed of the humidifying device, the liquid in the humidifying water pan 11 will gradually rise to the full water level during the humidification process. After the supply of humidifying liquid to the humidifying water pan 11 is stopped, the liquid in the humidifying water pan 11 will drop as the humidification time passes.

[0074] According to the embodiment of the present disclosure, step S130 may further include the following steps S131 to S132.

[0075] In step S131 , when it is detected that the liquid in the humidifying water pan 11 drops to the thirst level, the humidifying liquid is continuously supplied to the humidifying water pan 11 until the liquid in the humidifying water pan 11 rises to the full level.

[0076] In step S132, the humidifying unit 12 is controlled to stop operating.

[0077] According to the embodiment of the present disclosure, by adding liquid to the humidifying water tray 11 to a full water level and then discharging the liquid, that is, diluting the liquid in the humidifying water tray 11, it is possible to avoid excessive scale concentration in the humidifying water tray 11.

[0078] According to an embodiment of the present disclosure, after executing steps S110 to S130 a predetermined number of times, the control method may further include steps S150 to S160.

[0079] In step S150, when it is detected that the liquid in the humidifying water pan 11 drops to the thirst level, the humidifying liquid is continuously supplied to the humidifying water pan 11 until the liquid in the humidifying water pan rises to the full level.

[0080] In step S160 , the humidifying unit 12 is controlled to stop operating, and then the process returns to step S130 .

[0081] According to the embodiment of the present disclosure, after executing step S130, step S110 is re-executed and the execution times are recalculated, that is, the previous execution times are cleared.

[0082] According to the embodiment of the present disclosure, by performing steps S110 to S130 for a predetermined number of times, the liquid in the humidifying water tray 11 is added to the full water level and then discharged, that is, by a limited number of times of waiting to fill the water level before discharging the liquid, resources can be saved. The predetermined number of times can be set according to demand. For example, the predetermined number of times can include 2 times, 3 times and 4 times. In this embodiment, the predetermined number of times can be set to 2 times, that is, the liquid in the humidifying water tray 11 is added to the full water level and then discharged at every interval.

[0083] Figure 5 The flowchart schematically shows a control method of a humidifying device according to the second embodiment of the present disclosure.

[0084] like Figure 5 As shown, in this embodiment, the control method may include repeatedly executing the following steps S210 to S230.

[0085] In step S210 , humidifying liquid is supplied to the humidifying water tray 11 , and the humidifying rotor 121 is driven to rotate to humidify the gas flowing through the humidifying unit 1 .

[0086] In step S220 , when it is detected that the liquid in the humidifying water tray 11 drops to the thirst level, the humidifying rotor 121 is controlled to stop rotating to drain the liquid in the humidifying water tray 11 from the drain port 111 of the humidifying water tray 11 to the drain tray 4 .

[0087] In step S230 , after detecting that the humidifying rotor 121 stops rotating for a predetermined period of time, the drain part 2 is controlled to drain the liquid in the drain pan 4 .

[0088] According to the embodiment of the present disclosure, the drainage part 2 is controlled to drain the liquid in the drain pan 4 after detecting that the humidifying rotor 121 stops rotating for a predetermined period of time. Thus, the liquid in the drain pan 4 can be drained even when the liquid in the drain pan 4 has not reached a low water level, thereby avoiding the phenomenon of mold in the drain pan 4 and its components due to water accumulation in the drain pan 4.

[0089] According to the embodiment of the present disclosure, steps S210 to S230 may be repeatedly performed until the external space is humidified to a predetermined humidity. The predetermined humidity may be set by the user according to needs.

[0090] In some embodiments, step S240 may be further included before step S220. In step S240, when it is detected that the liquid in the humidifying water pan 11 rises to the full water level, the supply of humidifying liquid to the humidifying water pan 11 is stopped, and the humidifying rotor 121 continues to rotate to continuously humidify the gas. Since the humidifying speed of the humidifying device is lower than the water inlet speed of the humidifying device, the liquid in the humidifying water pan 11 will gradually rise to the full water level during the humidification process. After the supply of humidifying liquid to the humidifying water pan 11 is stopped, the liquid in the humidifying water pan 11 will drop as the humidification time passes.

[0091] According to an embodiment of the present disclosure, the humidifying device may further include a water valve. The water valve may include a main water valve 91 and a humidifying water valve 92. The main water valve 91 and the humidifying water valve 92 may be used to control the flow rate of the humidifying liquid provided by the external water supply to the humidifying water pan 11. The main water valve 91 and the humidifying water valve 92 may be connected in series. The main water valve 91 may be arranged upstream of the humidifying water valve 92. When the main water valve 91 is closed, the humidifying liquid cannot flow from the water supply to the humidifying water valve 92. The humidifying water valve 92 is located downstream of the main water valve 91. When the main water valve 91 and the humidifying water valve 92 are both opened, the liquid flows into the humidifying part 1 via the main water valve 91 and the humidifying water valve 92 in sequence. When the humidifying water valve 92 is closed, the liquid cannot enter the humidifying part 1.

[0092] When the water supply unit supplies humidifying liquid to the humidifying water pan 11, the main water valve 91 and the humidifying water valve 92 may be opened. When the water supply unit is controlled to stop supplying humidifying liquid to the humidifying water pan 11, the main water valve 91 and the humidifying water valve 92 may be closed.

[0093] In some embodiments, step S230 may also include the following steps S231 to S232.

[0094] In step S231, when it is detected that the liquid in the humidifying water tray 11 drops to the thirsty water level, the humidifying liquid continues to be supplied to the humidifying water tray 11 until the liquid in the humidifying water tray 11 rises to the full water level.

[0095] In step S232 , the humidifying rotor 121 is controlled to stop rotating so as to drain the liquid in the humidifying water pan 11 from the drain port 111 to the drain pan 4 .

[0096] According to the embodiment of the present disclosure, the liquid in the humidifying water tray 11 is filled to the full water level and then the liquid in the humidifying water tray 11 is drained to the drain tray 4, that is, the liquid drained to the drain tray 4 is diluted liquid, thereby avoiding excessive scale concentration in the drain tray 4.

[0097] In some embodiments, after executing steps S210 to S230 a predetermined number of times, the control method may further include steps S250 to S260.

[0098] In step S250, when it is detected that the liquid in the humidifying water tray 11 drops to the thirsty water level, the humidifying liquid continues to be supplied to the humidifying water tray 11 until the liquid in the humidifying water tray 11 rises to the full water level.

[0099] In step S260 , the humidifying rotor 121 is controlled to stop rotating so as to drain the liquid in the humidifying water pan 11 from the drain port 111 to the drain pan 4 , and then the process returns to step S230 .

[0100] According to the embodiment of the present disclosure, after executing step S230, step S210 is re-executed and the number of executions is recalculated, that is, the previous number of executions is cleared.

[0101] According to the embodiment of the present disclosure, by filling the liquid in the humidifying water pan 11 to the full water level and then draining it to the drain pan 4 after executing steps S210 to S230 for a predetermined number of times, that is, by draining the liquid after filling it to the full water level for a limited number of times, resources can be saved. The predetermined number of times can be set according to demand. For example, the predetermined number of times can include 2 times, 3 times, and 4 times. In this embodiment, the predetermined number of times can be set to 2 times, that is, the liquid in the humidifying water pan 11 is filled to the full water level and then drained once every interval.

[0102] In some embodiments, step S210 may further include: providing disinfectant liquid to the humidification water tray 11 to mix the disinfectant liquid with the humidification liquid, so as to humidify the gas based on the mixed liquid, thereby entering the disinfection mode.

[0103] According to an embodiment of the present disclosure, the water valve may further include a disinfectant water valve 93. The disinfectant water valve 93 may be used to control the flow rate of the disinfectant solution entering the humidifying water tray 11. When the disinfectant solution is provided to the humidifying water tray 11, the disinfectant water valve 93 may be opened. When the disinfectant solution is stopped from being provided to the humidifying water tray 11, the disinfectant water valve 93 may be closed. The disinfectant water valve 93 may be opened or closed simultaneously with the main water valve 91 and the humidifying water valve 92 to simultaneously provide the disinfectant solution and the humidifying solution to the humidifying water tray 11 or to simultaneously stop providing the disinfectant solution and the humidifying solution to the humidifying water tray 11, so as to ensure the stability of the concentration of the disinfectant solution in the humidifying water tray 11.

[0104] In some embodiments, the following steps S270 to S280 may be included before providing disinfectant to the humidifying water tray 11 .

[0105] In step S270 , the residual liquid in the disinfection unit 7 is drained to the drain pan 4 through the drain port 111 .

[0106] In step S280, a disinfectant is prepared.

[0107] According to the embodiment of the present disclosure, by draining the residual liquid in the disinfection part 7 to the drain pan 4 through the drain port 111 , it is possible to avoid the residual disinfectant from mixing with the new disinfectant, thereby affecting the concentration of the disinfectant provided to the humidification water pan 11 .

[0108] In some embodiments, step S250 may further include: when it is detected that the liquid in the drain pan 4 rises to a low water level, controlling the drain unit 2 to drain the liquid in the drain pan 4. Since the humidifying rotor 121 is always in a stationary state during the process of draining the residual liquid in the disinfection unit 7 to the drain pan 4, it is possible to determine whether to drain the liquid in the drain pan 4 by detecting whether the liquid in the drain pan 4 rises to a low water level.

[0109] According to the embodiment of the present disclosure, the residual liquid in the disinfection part 7 can be drained to the drain pan 4 through the drain port 111 by flushing the disinfection part 7, so as to ensure that the liquid in the drain pan 4 can rise to a low water level.

[0110] According to the embodiment of the present disclosure, the above control method can be executed by the controller 3 in the humidification device.

[0111] Third embodiment

[0112] Figure 6 The working flow chart of the humidification device according to the third embodiment of the present disclosure is schematically shown.

[0113] In this embodiment, the humidifying liquid is water, the driver is a motor, the predetermined value is 2, and the drainage part is a drainage pump.

[0114] like Figure 6 As shown, the control method of this embodiment includes steps S301 to S313.

[0115] Step S301: Enter the humidification state, and execute step S302;

[0116] Step S302: Fill the humidification water pan with water until it is full, and then execute step S303;

[0117] Step S303: the count value of the counter is increased by 1, and step S304 is executed;

[0118] Step S304: humidify the water in the humidification water tray until there is no water at the thirsty water level, and then execute step S305;

[0119] Step S305: determine whether the count value is greater than or equal to 2, if yes, proceed to step S306, if not, proceed to step S308;

[0120] Step S306: Open the main water valve and the humidification water valve, fill the humidification water pan with water until it is full, and execute step S307;

[0121] Step S307: clear the count value of the counter and execute step S308;

[0122] Step S308: Control the motor to stop working, and execute steps S309 and S310;

[0123] Step S309: determine whether the duration of the humidification unit stopping operation reaches a predetermined duration, if yes, execute step S311, if no, execute step S309 again;

[0124] Step S310: Determine whether there is water at the lower water level of the drain pan, if yes, execute step S311, if no, execute step S310 again;

[0125] Step S311: Control the drainage pump to drain water, and execute step S312;

[0126] Step S312: determine whether to continue humidification, if yes, execute step S301, if no, execute step S313;

[0127] Step S313: End humidification.

[0128] In addition, in order to control the water intake, a water inlet valve for controlling the water intake can be set at the water inlet of the humidifier installed on the ceiling. 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 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.

[0129] In order to solve the above-mentioned deficiencies of the prior art, the states of the main water valve 91 and the humidifying water valve 92 can be controlled to detect whether there are any abnormalities in the main water valve 91 and the humidifying water valve 92 .

[0130] Specifically, the controller 3 can be used to control the main water valve 91 and the humidification water valve 92 to open alternately, and based on the detection result of the detection unit 5, it can be determined whether the main water valve 91 and / or the humidification water valve 92 are abnormal. By controlling the humidification water valve 92 and the main water valve 91 to open or close alternately, the humidification water valve 92 and the main water valve 91 are alternately detected, so that it can be determined whether any of the humidification water valve 92 and the main water valve 91 is abnormal, and the purpose of facilitating the detection and maintenance of the water valve can be achieved.

[0131] According to the embodiment of the present disclosure, the main water valve 91 and the humidification water valve 92 are controlled to open alternately, and based on the detection result of the detection unit 5, it is determined whether there is an abnormality in the main water valve 91 and / or the humidification water valve 92, which may include: after the humidifying liquid in the humidification device is discharged, the main water valve 91 is controlled to open, the humidification water valve 92 is closed, and the water supply unit operates for a period of T1. When the detection unit 5 detects that the humidifying liquid has reached a predetermined position, it is determined that the humidification water valve 92 is closed abnormally.

[0132] According to the embodiment of the present disclosure, the main water valve 91 and the humidification water valve 92 are controlled to open alternately, and based on the detection result of the detection unit 5, it is determined whether there is an abnormality in the main water valve 91 and / or the humidification water valve 92. It can also include: after controlling the humidification liquid in the humidification unit 1 to be discharged, the humidification water valve 92 is controlled to open, the main water valve 91 is closed, and the water supply unit is operated for a T2 period. When the detection unit 5 detects that the humidification liquid has reached a predetermined position, it is determined that the main water valve 91 is closed abnormally.

[0133] According to an embodiment of the present disclosure, the predetermined position can be set according to demand, and the predetermined position can be a thirsty water level or a full water level. The T1 period can be characterized as the time required for the humidifying liquid in the humidifying section 1 to rise from the bottom of the humidifying liquid to the predetermined position when the main water valve 91 is fully opened and the humidifying water valve 92 is opened at any angle. The T2 period can be characterized as the time required for the humidifying liquid in the humidifying section 1 to rise from the bottom of the humidifying liquid to the predetermined position when the humidifying water valve 92 is fully opened and the main water valve 91 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 91 is controlled to open, the humidifying water valve 92 is closed, and the water supply section is operated for 5 minutes, that is, T1 is 5 minutes. When the detection unit 5 detects that the humidifying liquid has reached the thirsty water level, it is determined that the humidifying water valve 92 is closed abnormally, that is, the predetermined position can be the thirsty water level. For example, after controlling the humidifying liquid in the humidifying part 1 to be discharged, the humidifying water valve 92 is controlled to be opened, the main water valve 91 is closed, and the water supply part runs for 5 minutes, that is, T2 is 5 minutes. When the detection part 5 detects that the humidifying liquid has reached the full water level, it is determined that the main water valve 91 is abnormally closed, that is, the predetermined position can be the full water level.

[0134] According to an embodiment of the present disclosure, the controller 3 can also be used to control the humidifying device to enter a cleaning mode. Controlling the humidifying device to enter a cleaning mode may include: controlling the humidifying water valve 92 and the main water valve 91 to open, the water supply unit to operate, and controlling the humidifying rotor 121 to rotate to enter a water injection sub-mode. When the second detection unit detects that the humidifying liquid has reached the full water level, the controller 3 controls the humidifying water valve 92 and the main water valve 91 to close, and controls the humidifying rotor 121 to stop rotating, so as to roughly discharge the liquid in the humidifying unit 1. After roughly discharging the liquid in the humidifying unit 1, the humidifying rotor 121 is controlled to rotate again to enter a drying sub-mode for discharging the residual liquid in the humidifying unit 1.

[0135] Furthermore, in the drying sub-mode, the controller 3 can control the main water valve 91 and / or the humidifying water valve 92 to open alternately, and based on the detection result of the detection unit 5, determine whether there is an abnormality in the main water valve 91 and / or the humidifying water valve 92, so that while achieving drying, the operation status of the humidifying water valve 92 and the main water valve 91 can be determined to avoid damage to the humidifying water valve 92 and the main water valve 91 that causes 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.

[0136] According to the embodiment of the present disclosure, in the humidification mode, the heating part 8 can be turned on. In the water injection sub-mode, the heating part 8 can be turned off. In the drying sub-mode, the speed of the humidification rotor 121 can be adjusted to the maximum speed, and the heating part 8 can be turned on again to improve the drying efficiency, thereby effectively preventing the generation of mold.

[0137] According to the embodiment of the present disclosure, the controller 3 controls the main water valve 91 and the humidification water valve 92 to open. After the external water supply unit runs for a period of T3, and the detection unit 5 detects that the humidification liquid has not reached the predetermined position, it is determined that the main water valve 91 and / or the humidification water valve 92 are abnormally opened. The predetermined position can be a thirsty water level and / or a full water level. For example, in the water injection sub-mode, under normal operation, after the humidification water valve 92 and the main water valve 91 are opened, after the T3 period, for example, T3 is 5 minutes, the detection unit 5 should detect that the humidification liquid has reached the thirsty water level. After time T5, for example, T5 is 10 minutes, the detection unit 5 should detect that the humidification liquid has reached the full water level. In the case of abnormal opening of the main water valve 91 and / or the humidification water valve 92, after the humidification water valve 92 and the main water valve 91 are opened, after the T3 period, for example, T3 is 5 minutes, the detection unit 5 cannot detect that the humidification liquid has reached the thirsty water level. After time T5, for example, T5 is 10 minutes, the detection unit 5 cannot detect that the humidifying liquid has reached the full water level. T3 can be expressed as the time required for the humidifying liquid to reach the thirsty water level from the bottom of the humidifying unit 1 when both the humidifying water valve 92 and the main water valve 91 are open. T5 can be expressed as the time required for the humidifying liquid to reach the full water level from the bottom of the humidifying unit 1 when both the humidifying water valve 92 and the main water valve 91 are open. T3 and T5 can be set according to demand. T3 can also be expressed as the time required for the humidifying liquid to reach the thirsty water level from the bottom of the humidifying unit 1 when both the humidifying water valve 92 and the main water valve 91 are opened at any angle. T5 can also be expressed as the time required for the humidifying liquid to reach the full water level from the bottom of the humidifying unit 1 when both the humidifying water valve 92 and the main water valve 91 are opened at any angle. T5 can also be expressed as the time required for the humidifying liquid to reach the full water level from the thirsty water level when both the humidifying water valve 92 and the main water valve 91 are opened at any angle. By setting T3 and T5, it can be determined whether the humidification water valve 92 and the main water valve 91 are fully opened or fully closed.

[0138] According to the embodiment of the present disclosure, the controller 3 controls the main water valve 91 and the humidifying water valve 92 to be opened. After the external water supply unit runs for a period of T3, and the first detection unit detects that the humidifying liquid has not reached the predetermined position for N consecutive times, it is determined that the main water valve 91 and / or the humidifying water valve 92 are abnormally opened. The predetermined position includes a thirsty water level and / or a full water level. In order to avoid misjudgment, after the external water supply unit runs for a period of T3, the humidifying liquid can be detected once every period of time. When the number of detections reaches a preset number of times, it can be determined that the main water valve 91 and / or the humidifying water valve 92 are abnormally opened, thereby avoiding misjudgment due to water shortage and other reasons. After the external water supply unit runs for a period of T3, when it is detected for the first time that the humidifying liquid has not reached the predetermined position, the humidifying device can be controlled to enter a dormant mode. When it is determined that the main water valve 91 and / or the humidifying water valve 92 are abnormally opened, the humidifying 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 91 and / or the humidification water valve 92 are opened normally during the process of adding the humidification liquid to the full water level, which will not be described in detail here.

[0139] According to an embodiment of the present disclosure, in the cleaning mode, after the second detection unit detects that the humidifying liquid has reached the full water level, the controller 3 controls the humidifying water valve 92 and the main water valve 91 to close and controls the humidifying rotor 121 to stop rotating for a period of T4, and the second detection unit detects that the liquid is always at the full water level, it is determined that the main water valve 91 and / or the humidifying water valve 92 are abnormally closed. T4 can be 3 hours. T4 can be expressed as the time required for the liquid in the humidifying unit 1 to be significantly consumed. It should be noted that the drain outlet 111 of the humidifying device is small and the drainage speed is slow, that is, when the main water valve 91 and / or the humidifying water valve 92 are opened, the drainage speed of the humidifying device is less than or equal to the liquid inlet speed of the humidifying device.

[0140] In the above process, when it is determined that the main water valve 91 and / or the humidification water valve 92 are abnormally opened, or when it is determined that the main water valve 91 and / or the humidification water valve 92 are abnormally closed, the main water valve 91 and the humidification water valve 92 can be closed to control the humidification device to shut down.

[0141] According to the embodiment of the present disclosure, when it is determined that the water filling sub-mode operates normally and when the second detection unit detects that the humidifying liquid reaches the full water level, the drying sub-mode is entered.
