Based on the implementation of the control method, the water in the humidifying water tank 2 can be discharged in time, and the humidifying element is closed and the water inlet is stopped while the water is discharged, so that the safety of the operation of the humidifying device can be ensured.
Further, the preset drainage conditions include: the accumulated humidifying operation time of the humidifying device exceeds the preset operation time, and the ion concentration in the humidifying water tank 2 exceeds the preset scaling concentration.
When the water supply source of the humidification devices such as the electric heating humidification device is water with high concentration of strong electrolyte such as common tap water, softened water and the like, the water supply source is used for a long time, scales can be attached to the wall surfaces of the heating device 13 and the humidification water tank 2, if the scales are not cleared and cleaned in time, the output performance of the humidification device can be influenced, the scales can be clamped on a water inlet valve member, a detection device and other components, the service life of other devices in the humidification device and the accuracy of detection and feedback are influenced, and even the humidification device runs out of control.
In the embodiment, the scaling condition in the humidification water tank 2 can be measured under the conditions of the preset operation time and the preset scaling concentration, so that water is automatically drained when scaling is serious, impurities such as scale and sludge are discharged out of the humidification water tank 2, and efficient humidification is guaranteed.
The ions causing the humidification device to scale mainly include calcium ions, accordingly, the detected ions are calcium ions, the preset scaling concentration is specifically set to be 400mg/L for example, and when the calcium ion concentration in the water exceeds 400mg/L, it is determined that the ion concentration in the humidification water tank 2 exceeds the preset scaling concentration. Of course, in other embodiments, the preset scaling concentration may be set to 405mg/L, for example, the detected ions are calcium ions. Or, in another embodiment, the detected ions may further include other ions that may cause scale, for example, magnesium ions, and accordingly, the preset scaling concentration includes preset scaling concentrations corresponding to the respective ions, and as long as the concentration of one of the ions exceeds its corresponding preset scaling concentration, it is determined that: the ion concentration in the humidification water tank 2 exceeds the preset scaling concentration.
Further, after the water is drained under the condition that the accumulated humidifying operation time of the humidifying device exceeds the preset operation time and the ion concentration in the humidifying water tank 2 exceeds at least one preset drainage condition of the preset scaling concentration, the water changing operation is also included. The water changing operation specifically comprises:
s3: the electric drainage device 6 is controlled to be repeatedly closed and started for preset times, the water inlet device is controlled to be started when the electric drainage device 6 is closed, the water inlet device is controlled to be closed when the electric drainage device 6 is started, and the opening and closing conditions of the water inlet device are opposite to those of the drainage device.
Specifically, S3 may be executed by the control device in the humidifying device.
That is to say, after the water discharging operation is performed once, the water discharging device and the water inlet device are continuously controlled to be alternately opened and closed to repeatedly flush the humidifying water tank 2 and internal parts thereof, other cleaning equipment is not needed, and the water flow is directly flushed to realize self-cleaning of the scale.
Alternatively, the on and off periods of the electric drain device and the number of times of the on and off may be preset in one water change operation. After the water changing operation is finished, the control device controls the electric drainage device to be closed and controls the water inlet device and the humidifying element to be opened so as to recover the normal humidifying operation.
Further, the preset drainage condition further comprises: the water level in the humidification water tank 2 is higher than a preset safe water level.
When humidification device's water installations trouble or relevant protector became invalid, probably lead to the higher partial out of control of water level in humidification water tank 2, if not stopping the humidification, probably lead to humidification efficiency greatly reduced, for example, to electric heat humidification device, when the water level was higher, if not stopping the humidification heating, the water of boiling easily blockked up the steam outlet in humidification water tank 2 to flow out from the humidification device spray lance, humidification efficiency greatly reduced.
In this embodiment, the preset safe water level can be used as a reference for measuring the safety of the water level, and when the water level exceeds the preset safe water level, the water discharging operation is performed, that is, the humidifying element is turned off, the water discharging device is turned on, and the water inlet device is turned off, so as to avoid the exceeding of the water level and ensure the humidifying efficiency.
Optionally, when the water level exceeds the preset safe water level, the control device can also output a fault signal of the humidifying device to the upper computer.
Alternatively, when the water level in the humidification water tank 2 is higher than a preset safe water level, the trigger signal is a water level high float output signal.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
