Based on the above technical solution, optionally, as shown in fig. 26 to fig. 28, the top surface of the wet film forms a corrugated surface 2222, the water spraying module further includes a throttle pipe 333, and the throttle pipe 333, the water inlet valve 32, and the water sprayer 31 are sequentially connected.

Specifically, in the use process, the water inlet valve 32 controls the on-off of water supply, when water is supplied, the inlet water flows through the throttle pipe 33 to control the total flow in the pipe within a certain range (for example, 300 +/-50 mL of domestic water pressure), and then the water flow is distributed to the wet membrane module 22 below through the water spraying holes 301 according to the requirement. And the water flows in the depression 223 downward through the first and second water inlet holes 224 and 225.

The water flowing down from the first water inlet 224 is uniformly distributed through the corrugated surface 2222, so that the humidifying wet film is uniformly soaked and washed, better water supply uniformity is achieved, and the service life of the humidifying wet film is prevented from being shortened due to overlarge flushing water quantity. And since the first water inlet hole 224 is disposed at the center, the protrusions and grooves formed for the corrugated surface 2222 extend in the length direction of the wet film 222 to allow water to be uniformly distributed.

More importantly, because the installation is hung to the central humidifying equipment of suspension type adoption furred ceiling, in the installation, then the condition of slope around can appearing, and through the solution that configuration corrugated surface 2222 can be better lead to rivers uneven distribution because of installation error, utilize corrugated surface 2222 to lead to rivers for water can follow the length direction evenly distributed of wet membrane 222.

In addition, the branched water is also stored in the water tank 21 for humidification, thereby achieving an effect of securing a water replenishing speed of the water tank 21 while limiting the amount of flush water supplied to the wet film 222.

The representation entity of the throttle pipe 33 may adopt a water pipe structure having a throttling function in the conventional technology, which is not limited and described herein.

Through increasing the throttle pipe in the trickle module, utilize the throttle pipe to come to carry out the throttle processing to the discharge of input, thus, in the water supply process, alright sharp change because of water pressure fluctuation causes discharge in effectual reduction, and simultaneously, the reposition of redundant personnel of cooperation trickle hole and first inlet opening is handled, can be better supply with water evenly distributed, in addition, form the ripple face through the top surface with wet membrane, utilize the ripple face for guide rivers direction, and then can ensure evenly to soak, wash the wet membrane of humidification, avoid the life-span of the wet membrane of humidification because of the too big result of the flushing volume to subtract short when reaching better water supply homogeneity, realize the water supply flow of convenient control central humidification equipment and improve the wet membrane wetting homogeneity, in order to improve the humidification effect.

In order to meet the requirement of automatic control, a controller (such as a singlechip and the like) is integrated in the electric control board. The specific control method is that when the central humidifying device starts the humidifying function, the controller is configured to enable the first water level detector 26 to detect that the water level value is smaller than the first water level value to trigger the water inlet valve 32 to be opened, and the controller is further configured to enable the first water level detector 26 to detect that the water level value is larger than the second water level value to trigger the water inlet valve 32 to be closed.

Specifically, in the central humidification apparatus performing the humidification mode, the on-off of the water supply is controlled according to the water level in the water tank 21. The first water level detector 26 sends a water level value signal to the controller, and the water inlet valve 32 is controlled to open or close to cut off water correspondingly by the controller, so that the wet film 222 can be well and uniformly wetted on one hand, and excessive water in the water tank 21 is also avoided on the other hand.

In another embodiment, in the using process, under the condition that the electrical components have faults, the situation that water cannot enter or water cannot be shut down further occurs.

To this end, the control method further includes: the controller is further configured to alarm for water supply anomalies when the first water level detector 26 detects a water level value that is continuously less than the first water level value and a duration that exceeds the first duration value.

Specifically, in the humidification mode, after the controller controls the water inlet valve 32 to open the water supply, if the first water level detector 26 detects that the water level value is continuously smaller than the first water level value, it indicates that no water is supplied to the humidification module 2, and at this time, an abnormal water supply alarm is performed. The alarm mode can adopt conventional alarm modes such as sound, light, electricity and the like, and is not limited and described herein.

In another embodiment, the controller is further configured to activate the drain pump when the first water level detector 26 detects a water level value that is continuously greater than the second water level value for a time period that exceeds a second time period value.

Specifically, in the humidification mode, after the controller controls the water inlet valve 32 to open the water supply, if the water level exceeds the second water level value of the water tank 21, the water inlet valve 32 should be closed. In case of a fault of the water inlet valve 32, the drainage pump is activated to drain water in case that the water level in the water tank 21 continuously exceeds the second water level value and the duration time exceeds the second duration value. In this case, the water supply abnormality alarm can be started.

Further, the controller is configured to alarm the water supply abnormality after the first water level detector 26 detects that the water level value is continuously greater than the second water level value and the duration time exceeds the third duration value after the drain pump is started.

Specifically, in the humidification mode, when the drainage of the drainage pump is started, if the second water level value and the duration time exceed the third time length value, it indicates that the drainage pump is in failure, and a water supply abnormality alarm needs to be given in time.

In another embodiment, after the central humidification device turns off the humidification function, since a certain amount of water still exists in the water tank 21, in order to prevent the wet film 222 from mildewing due to soaking in water for a long time, the water in the water tank 21 needs to be drained timely.

To this end, the control method further includes that the controller is further configured to activate the electric heating part to dry the wet film after activating the drainage pump to drain the water in the water tank into the water pan and after the first water level detector detects that the water level value is continuously lower than the first water level value and the duration exceeds a fourth duration value.

Specifically, after the central humidifying device turns off the humidifying function, the controller will activate the drain pump to drain the water in the water tank 21 to the lower water receiving tray 6. The water level in the water tank 21 drops below the first water level value, and after the first water level detector detects that the water level value continues to be lower than the first water level value and the duration time exceeds the fourth time length value, indicating that the water in the water tank 21 is completely drained, the electric heating part 72 may be activated to dry the wet film 222.

Meanwhile, after the first water level detector detects that the water level value is continuously lower than the first water level value and the duration time exceeds the fourth time length value, the controller will simultaneously turn off the drain pump 23.

In some embodiments, the first water level detector 26 includes a lower level switch 261 having a height lower than that of the upper level switch 262, and an upper level switch 262 electrically connected to the controller, respectively.

Specifically, in order to accurately detect the water level in the water tank 21, two level switches arranged up and down are used to detect the water level. The lower level switch 261 is used to match a first water level value during testing and the upper level switch 262 is used to match a second water level value during testing.

In some embodiments, in order to facilitate uniform assembly, a support rod (not shown) is disposed in the water tank, and the lower liquid level switch and the upper liquid level switch are disposed on the support rod.

Specifically, in the assembling process, the lower liquid level switch and the upper liquid level switch are both mounted on a support rod, and then a floating ball is further arranged on the support rod and floats according to the liquid level in the water tank 21 to trigger the conduction action of the lower liquid level switch and the upper liquid level switch. When the lower floater of the water level in the water tank 21 descends to the position of the lower liquid level switch, the lower liquid level switch is triggered to be switched ON through the floater, the lower liquid level switch can start the ON working state, and the water supply waterway can start to supply water. When the water level in the water tank rises, the floating ball correspondingly rises to the position of the upper liquid level switch, the upper liquid level switch is triggered to be switched ON through the floating ball, the upper liquid level switch can start the ON working state, and the water supply waterway stops supplying water.

Through utilizing integrative high low level floater, realize the inside water demand of basin, when humidification system stopped the humidification, the drainage will be opened to the water pump in the aqua storage tank, with the inside surplus water volume of aqua storage tank arrange the water collector in.

In another embodiment, the water in the water tank 21 is kept clean during use to improve the humidifying effect. Then under the humidification mode, after equipment continuous operation sets for the duration, equipment will wash and trade water operation, specifically do: the controller is configured to trigger the drainage pump to drain all water in the water tank 21 after the equipment continuously operates for a set operation time, and automatically trigger to open the water inlet valve 32 to continuously perform water spraying cleaning on the water film 222 in the drainage process because the water level in the water tank 21 is lower than the first water level value. The controller turns off the drain pump and controls the water level in the water tank 21 between the first and second water level values by means of the first water level detector after performing the above-described operation process for a set maintenance time period, so that the water film 222 continues to humidify.

Through carrying out thorough effectual change to the water in the basin 21 to the cooperation drenching module is carried out the trickle and is washd wet membrane, and the quality of water in the basin 21 worsens and causes the humidification effect to reduce after solving equipment long-time continuous operation. After the above operation is performed, the water tank 21 can be replaced with new water, and the wet film 222 can be cleaned to obtain a good humidification effect.

In one embodiment, a second water level detector 61 is arranged in the water pan, the second water level detector is electrically connected with the controller, and the controller is configured to trigger the drainage pump to stop working and perform an overflow alarm when the second water level detector detects that the water level value is continuously greater than a third water level value and the duration time exceeds a fifth time value.

Specifically, the second water level detector 61 is provided in the drip tray 6 to detect the level of water in the drip tray 6 by the second water level detector 61. In the case where the drain pipe smoothly drains, the water drained from the drain pump 23 into the drain pan 6 is automatically drained to the outside through the drain pipe 62.

When the drain pipe 62 is blocked to cause poor drainage, the water level in the drip tray 6 is gradually raised. When the second water level detector 61 detects that the water level is higher than the third water level value and the duration time exceeds the fifth duration value, it indicates that the drain pipe 62 of the water pan 6 is blocked to cause the water pan 6 to fail to drain or the upper level switch 262 in the water tank 21 fails to cause the water channel to supply water all the time and overflow from the water tank 21 occurs. At this time, the drainage pump 23 is triggered to stop working and an overflow alarm is given.

In one embodiment, the second water level detector 61 may be an overflow float installed in the drip tray 6. The working principle of the overflow floating ball is that when the drainage pump 23 in the water tank 21 drains water into the water receiving tray 6, the controller stops draining the water by the drainage pump 23 in the water tank 21 after the overflow floating ball is triggered by the rising of the buoyancy of the water in the water receiving tray 6, so that the humidification system is protected to prevent overflow risks.

Through the combination of utilizing high low level floater and overflow floater, can realize the system and according to the required control that carries out the water yield water level of humidification volume, can realize drainage overflow risk again and report to the police, the practicality is strong, and the security is high.

In another embodiment, a wind pressure switch 46, a first temperature sensor 47, a second temperature sensor 40 and a humidity sensor 48 are disposed in the housing, the wind pressure switch, the first temperature sensor and the humidity sensor are disposed at the air inlet and electrically connected to the controller, respectively, and the second temperature sensor is disposed at the air outlet and electrically connected to the controller.

Specifically, after the central humidifying device starts the humidifying function, the controller detects relevant starting parameters according to the wind pressure switch 46, the first temperature sensor 47 and the humidity sensor 48 to determine whether the starting conditions are met, and then starts the water inlet valve 32 to open for humidifying operation.

Wherein the control method further comprises, upon activation of the humidification function by the central humidification apparatus, the controller being configured to activate the electric heating means if conditions one, two and three are satisfied; the first condition is that the wind pressure detected by the wind pressure switch is greater than a set wind pressure; the second condition is that the temperature value detected by the first temperature sensor is lower than a set temperature value; and the third condition is that the humidity value detected by the humidity sensor is lower than the set humidity value.

Specifically, the humidifier starts to humidify, and the system detects whether the air pressure switch meets a first set condition, so that when the air volume is low or no air volume exists, the electric heating part 72 is prevented from being dried, and the reliability of electric heating is ensured; when the condition is met, the first temperature sensor detects whether the temperature of the air inlet dry bulb meets a second set condition, and when the air inlet temperature is too high, the electric heating part 72 is prohibited to be started in order to protect the electric heating part 72 and surrounding plastic parts from being too high and influence the reliability of the product; when the condition two is met, the humidity sensor 48 detects whether the temperature of the inlet air wet bulb meets the setting condition three, when the humidity is higher, the electric heating component 72 is started to increase the humidification quantity, and when the air with high temperature and high humidity passes through the normal-temperature air channel, condensation is possibly caused, the reliability of the product is influenced, and the electric heating component 72 is prohibited to be started.

When the third condition is satisfied, the controller is further configured to control the heating power of the electric heating part according to the temperature value detected by the second temperature sensor. The system detects the air-out temperature, and according to air-out temperature and the temperature difference of air inlet, opens electric heating element 72 by gear, guarantees that the air-out temperature is in human comfortable temperature range.
