In addition, a water inlet 110 for injecting water into the inner space is provided at the top, the water inlet 110 is coupled to the water inlet cover 111. The water inlet cover 111 may prevent inflow of dust and foreign substances into the water tank 100 and may also prevent outflow of water to the outside.

In this way, the water inlet 110 is provided at the top, it is possible to replenish the water in the water tank 100 without removing the water tank 100 from the main body 200, and further replenish the water to the humidifier If this is required, the elderly and women can easily replenish water. That is, the water replenishment to the water tank 100 can be facilitated as well as to increase the convenience of use.

In addition, the main body 200 is coupled to the water tank 100 having a check valve 140 at the bottom, the water flowing out of the water tank 100 is in the reservoir 220 formed in the main body 200 Is stored.

In addition, the reservoir 220 is provided with a water level sensor 230 for detecting the water level, the operating rod 211 provided in the solenoid 210 in accordance with the water level signal transmitted from the water level sensor 230 Will optionally be in Shanghai-dong. As a result, the operating rod 211 moves up and down to open and close the check valve 140. Accordingly, water is discharged from the water tank 100 to maintain a constant amount of water in the reservoir 220. It becomes possible.

In detail, the water supply unit 120 is formed on the lower side of the water tank 100, the water tank cap 130 is preferably coupled to the end of the water supply unit 120 by a coupling method such as screwing, It is preferable that a sealing member is provided inside the water tank cap 130 so that water inside the water tank 100 does not flow out.

Here, the water tank cap 130 has a supply passage 131 is formed through the inside, the check passage 140 for opening and closing the supply passage 131 so that the outflow of water can be selectively made in the supply passage 131. ) Is provided.

On the other hand, the check valve 140 is coupled to the upper end of the coupling member 150 facing the inner side of the water tank 100, the coupling member 150 is provided in the flow path direction of the supply passage 131. In addition, the elastic member 151 is coupled to the other end of the coupling member 150 facing the outside of the water tank 100.

Herein, the elastic member 151 is provided to support the check valve 140 in a direction that closes the supply flow path 131, so that the water contained in the water tank 100 does not flow out.

In addition, the direction in which the elastic member 151 elastically supports the check valve 140 is the same as the direction of the hydraulic pressure applied to the check valve 140 by the water contained in the water tank 100 Sealing of the check valve 140 can be made easier and more secure.

Therefore, the check valve 140 may maintain a state in which the supply passage 131 is always sealed unless an external force greater than the hydraulic pressure applied to the elastic member 151 and the check valve 140 is applied.

Here, the check valve 140 may be made of a rubber material, the elastic member 151 may be made of an elastic body such as a spring.

On the other hand, when the check valve 140 is opened, the water contained in the water tank 100 is introduced into and stored in the reservoir 220 formed in the main body 200 through the supply passage 131, the reservoir 220 The water stored in) is atomized by the vibrator 240 that atomizes water by using ultrasonic waves, and the atomized atomized particles are discharged to the outside of the humidifier through the spray hole 250.

As the water is atomized and jetted in this manner, the water level of the water stored in the reservoir 220 is changed, so that the water level sensor 230 capable of measuring the water level of the water stored in the reservoir 220 is provided.

Here, the main body 200 is provided with a control unit 260 for controlling the operation of the solenoid 210 receives the water level detection signal measured from the water level sensor 230.

On the other hand, the humidifier equipped with the solenoid 210 as described above may be the operating noise generated by the operating rod 211 provided in the solenoid 210 when water is supplied.

Here, it is more preferable to use the shock absorbing member for the solenoid 210 or to use the solenoid 210 of the low speed operation.

At this time, the operating rod 211 of the solenoid 210 may be filled with lubricant to lower the moving speed of the operating rod 211.

However, when operating the solenoid 210 for water supply, if the operating speed of the operating rod 211 is reduced to open the check valve 140 slowly, an air film is formed around the check valve 140 to supply water. It may not be smooth.

In the humidifier according to an embodiment of the present invention to improve such a phenomenon, by controlling the operation method of the solenoid 210 to be operated in various steps, it provides a control method that can be more smoothly supplied water.

In detail, if a certain amount of water is atomized during the humidification and is discharged into the atmosphere through the spray port 250, the water stored in the reservoir 220 of the main body 200 is reduced to lower the water level. At this time, when the level detection signal is sent to the controller 260 by the water level sensor 230, the controller 260 operates the solenoid 210. At this time, the operating rod 211 provided at the center of the solenoid 210 is raised to raise the check valve 140, thereby opening the supply passage 131 to start supplying water into the reservoir 220.

Here, when the check valve 140 is raised in the supply passage 131, a phenomenon may occur in which an air film is formed around the open space of the supply passage 131 so that water supply may not be performed smoothly.

However, in the humidifier according to an embodiment of the present invention, once the operating rod 211 of the solenoid 210 is raised for a set time to supply water, even after the set time has elapsed, the water level of the reservoir 220 reaches the set value. If the water is not supplied smoothly, the controller 260 turns on / off the solenoid 210 one or more times to operate it intermittently, thereby elevating the operating rod 211 one or more times.

The set time is preferably a time preset by the controller.

Through this, the operating rod 211 is lifted one or more times by the intermittent operation of the solenoid 210, it is possible to artificially remove the air film, the water supply is made smoothly.

If the water level of the reservoir 220 does not reach the set value even after the intermittent operation of the solenoid 210, it indicates that there is no water. On the other hand, when the water level of the reservoir 220 reaches the set value, the solenoid 210 is normally stopped.

In addition, the intermittent operation of the solenoid 210 is preferably made to be variously adjusted depending on the case or more.

2 is a block diagram showing a solenoid operation step of the humidifier according to an embodiment of the present invention.

As shown in FIG. 2, the actuation of the actuating rod 211 by the solenoid 210 may be performed by setting the solenoid 210 on for a set time so that the actuating rod 211 is raised to lift the check valve 140. A first step of opening and a second step of opening / closing the check valve 140 one or more times by elevating the operating rod 211 one or more times by intermittently operating the solenoid 210 on / off one or more times. And a third step of displaying no water.

When the water level of the reservoir 220 does not reach the set value even after a certain time has elapsed after the indication of no water, it is determined that there is no water, the power is cut off.

At this time, when the water level below the initial set value is detected in the reservoir 220 by the water level sensor 230 when the humidifier is first powered on, the humidifier first turns on the solenoid 210 before starting the spraying of the humidifier. It is preferred that the step of supplying is preceded.

Through this, the humidifier according to an embodiment of the present invention by controlling the operation of the solenoid 210 to operate the operating rod 211, it is possible to ensure a smooth water supply at all times.

3 is a flowchart illustrating a method of controlling a humidifier according to an embodiment of the present invention.

As shown in FIG. 3, the control method of the humidifier determines whether there is no water on the basis of the initial setting value of the reservoir 220 measured by the water level sensor 230 when the power is initially applied, and whether the solenoid 210 is operated. Determining whether there is no water display (S1), and if the water level during spraying is less than the set value, judging the absence of water to determine whether or not the set time operation of the solenoid 210 (S2), and the setting of the solenoid 210 Determining the absence of water if the water level is less than the set value after time operation to determine the intermittent operation of the solenoid 210 (S3), and if the water level is less than the set value even after the intermittent operation of the solenoid 210 to display no water A step S4 is made.

Here, the set values are set differently, and the set values may be changed depending on the case.

In addition, the intermittent operation of the solenoid 210 in step S3 causes the operating rod 211 of the solenoid 210 to be moved by one or more times, thereby causing the supply flow passage 131 to be operated at least once by the check valve 140. It means opening and closing.

Referring to the operation of the humidifier according to an embodiment of the present invention configured as described above are as follows.

The humidifier detects the water level of the reservoir 220 by the water level sensor 230 when the power is initially applied. At this time, when the water level of the reservoir 220 is detected below the initial set value, the solenoid 210 is first turned on before spraying the humidifier to start the preliminary operation of supplying water to the reservoir 220.

Through this, when the water level of the reservoir 220 reaches the initial set value, spraying is started. On the other hand, if it is determined that there is no water because the water level of the reservoir 220 does not reach the initial set value, it displays a no water indication.

Then, when the water level of the reservoir 220 during spraying falls below the set value, it is determined that there is no water to turn on the solenoid 210 for a set time. On the other hand, if the water level of the reservoir 220 during spraying is higher than the set value, the operation of the solenoid 210 is stopped and the water supply is blocked.

On the other hand, even after operating the solenoid 210 for a set time, if the water level of the reservoir 220 is less than the set value, it is determined that there is no water to turn on / off the solenoid 210 one or more times to operate the intermittent operation 211 )) One or more times. On the other hand, when the water level of the reservoir 220 rises above the set value, the operation of the solenoid 210 is stopped and the water supply is blocked.

And, even after the intermittent operation of the solenoid 210, if the water level of the reservoir 220 is less than the set value is displayed no water.

In addition, even after a certain period of time after the water-free display occurs, if the water level of the reservoir 220 does not reach the set value, it is determined that there is no water, the power is cut off.

Through this, the humidifier operates the solenoid 210 to correspond to the water level of the reservoir 220 to control the lift time and the lift cycle of the operating rod, thereby facilitating the water supply from the water tank 100 into the reservoir 210. You can.

As described above, the humidifier and its control method according to a preferred embodiment of the present invention is not limited to each of the above-described embodiments, without departing from the scope of the invention claimed in the prior art It is possible to carry out modification by the exciter, and such modifications are within the scope of the present invention.
