20 is a view showing a flow path extending from a pump according to an embodiment of the present invention.

Referring to FIG. 20, a supply passage 31 connected to the pump 5 according to an embodiment of the present invention may include a valve 880 that can open and close the supply passage 31. In the supply flow path 31, a vent flow path 316 may be branched. The vent flow path 316 can be opened and closed by a vent valve 317.

When the vent flow path 316 is opened by the vent valve 317, the inside and the outside of the supply flow path 31 are communicated with each other, so that the air can be opened and closed. When the vent flow path 316 is closed by the vent valve 317, the inside of the supply flow path 31 may be disconnected from the outside and become a closed space.

When the water pumped by the pump 5 flows through the supply passage 31, the vent passage 316 can be closed by the vent valve 317 so that water flowing through the supply passage 31 is not leaked. Before the water is pumped by the pump 5, the vent flow path 316 is opened to make the pressure inside and outside the supply flow path 31 equal.

This is because the pump 5 idles when the water tank 3 is detached or the water in the water tank 3 is insufficient or not in the state where the operation of the pump 5 is not stopped. The air may flow into the supply flow path 31. When the pump 5 is operated while air is flowing into the supply passage 31, noise may be generated and the pumping operation by the pump 5 may not be performed smoothly.

Therefore, before the operation of the pump 5, the vent valve 317 is opened to allow the air in the supply passage 31 to escape to the outside, so that the pressure is equalized with the outside, Can be smoothly performed.

On the other hand, the water tank 3 is connected to the pump 5 through a connection passage, and the supply passage 31 is connected to the pump 5. A vent flow path 316 is branched from the supply flow path 31. The vent flow path 316 is provided with a vent valve 317 to open and close the vent flow path 316. The supply flow path 31 can pass through a portion where the vent flow path 316 branches off and a valve 880 that opens and closes the supply flow path 31. The valve 880 may be provided to prevent backflow of water when the pump 5 is not pumped. That is, the water can flow only in one direction of the supply flow path 31 by the valve 880.

One side of the supply passage 31 may be connected to a distributor for supplying water to the humidification pad 20. [ That is, the water tank 3, the connection passage, the pump 5, the supply passage 31, the valve 880 and the distributor are connected in this order, and the supply passage 31 is provided with a vent passage 316 have. The vent flow path 316 may be positioned before the valve 880 in the supply flow path 31. [ The water flowing through the supply passage 31 can flow to the side where the valve 880 is located through the portion where the vent flow passage 316 is branched.

The vent valve 317 is provided in the vent passage 316 and can be selectively opened. The vent flow path 316 may be provided at a position higher than the maximum water level of the water tub 3. [

FIG. 21 is a flowchart illustrating a humidifying operation of the humidifying apparatus according to an embodiment of the present invention.

21, when the humidification mode of the humidifier 1 according to the embodiment of the present invention is set (S1), the controller provided in the humidifier 1 determines whether the state of the humidifier 1 is normal (S2). If the humidification mode is selected automatically or manually, whether or not the pump 5, the fan assembly 6, etc. of the humidifier 1 is normal, whether the water tank 3, the humidification pad 20, Can be inspected.

For example, in the case of the pump 5, if the amount of power higher than usual is detected, the humidifier 1 may be detected as abnormal. If the filter or the like is clogged by foreign matter or the amount of water in the water tank 3 is smaller than the reference amount, the load applied to the pump 5 may increase and the output amount of the pump 5 may be increased. Therefore, if the output level of the pump 5 is detected to be high and the humidification mode is not operated, the user can restart the humidification mode after taking measures such as replacing the filter or adding water to the water tank 3.

The humidification mode can be terminated when it is detected that the humidifier 1 is not normal due to a failure such as the pump 5 or the fan assembly 6 being detected.

If it is determined that the state of the humidifier 1 is normal, the vent valve 317 can be opened (S3). The vent valve 317 can be opened for a predetermined time. For example, the vent valve 317 may be pre-set to open within a range of 1 second to 10 seconds. By opening the vent valve 317 before the operation of the pump 5, the pressure inside and outside the supply passage 31 can be made equal, and the pumping operation by the pump 5 can be performed smoothly.

It is determined that the vent valve 317 has been opened for a predetermined time (S4). If it is determined that the predetermined time has elapsed, the vent valve 317 that is open can be locked (S5). The pump 5 and the fan assembly 6 can be operated after the vent valve 317 is locked so that water is not leaked through the vent flow path 316 (S6).

During operation of the pump 5 and the fan assembly 6, the control unit can detect whether the pump 5 and the fan assembly 6 are operating normally (S7). If it is determined that the pump 5 and the fan assembly 6 are operated normally, the humidification mode operation can be continuously performed. However, when it is detected that the pump 5 and the fan assembly 6 have failed and abnormal operation is performed The operation of the pump 5 and the fan assembly 6 is stopped (S8), and the humidification mode operation can be terminated.

In this way, when the humidifier 1 is judged not to be normal when the pump 5 and the fan assembly 6 of the humidifier 1 are judged to be abnormal, the humidifier 1 stops the humidification mode operation, It is possible to prevent the abnormal operation from continuing.

FIG. 22 is a flowchart related to the intermittent operation of the humidifier according to the embodiment of the present invention.

Referring to FIG. 22, the humidifier 1 according to an embodiment of the present invention may be provided to operate intermittently. This is to maintain humidification efficiency while minimizing component consumption. For example, in the case of the pump 5, the cumulative operation time at the time of manufacture can be roughly determined. Therefore, by allowing the pump 5 to operate intermittently, the life of the product of the humidifier 1 can be prolonged.

The pump 5 and the fan assembly 6 are operated (S10) to intermittently operate the humidifying apparatus 1 and the control unit detects whether the pump 5 and the fan assembly 6 are operating normally (S11). If the pump 5 or the fan assembly 6 is detected to be operating abnormally, the operation of the pump 5 and the fan assembly 6 can be stopped (S12).

If the pump 5 and the fan assembly 6 are detected to be operating normally, the pump 5 can operate for a predetermined time. Here, the operation time of the predetermined pump 5 may be equal to or longer than the time when the water pumped by the pump 5 can sufficiently wet the humidification pad 20.

The air blown by the fan assembly 6 can not pass through the humidification pad 20 if the humidification pad 20 is wetted by 100%. Therefore, depending on the performance of the fan assembly 6 and the environment of the humidifier 1, The pumping time of the pump 5 can be preset so that the pad 20 can be properly wetted. For example, the pumping time of the pump 5 may be set so that the humidification pad 20 is wetted by about 30%.

If it is detected that the preset time has elapsed (S13), the control unit can stop the operation of the pump 5 (S14). The pump 5 can be kept stationary by turning off the power for a predetermined time. The stopping time of the pump 5 can be set in a range of approximately 30 seconds to 5 minutes. Even if the pump 5 is stopped, since the humidifying pad 20 is in a wet state, the fan assembly 6 can be operated to continue the humidifying operation.

The control unit detects whether or not the stop time of the pump 5 has elapsed (S15), and if it is detected that the predetermined stop time of the pump 5 has elapsed, the pump 5 can be restarted. Both the pump 5 and the fan assembly 6 are operated, and the humidification operation can be continuously performed.

When the pump 5 is restarted, the pump 5 starts to be supplied within the range of 50% to 70% of the rated output and can be gradually controlled to reach 100% of the rated output. In this way, since the output supplied to the pump 5 is gradually increased, it is possible to solve the problem of noise generation that may occur suddenly when the pump 5 is restarted.

FIG. 23 is a flow chart for notifying a filter replacement period of a humidifier according to an embodiment of the present invention.

Referring to FIG. 23, the filter assembly 4 provided in the humidifier 1 according to the embodiment of the present invention needs to be replaced after a predetermined period of time in order to prevent the filtering efficiency from being lowered. The humidifying device 1 may be provided with an alarm function for notifying when the filter assembly 4 is to be replaced.

When the humidification mode is set (S20), the control unit can detect whether the usage time of the filter assembly 6 has passed the preset time (S21). If it is determined that the use time of the filter assembly 6 has not exceeded the preset time, the humidification operation can be performed (S22). If it is determined that the use time of the filter assembly 6 has passed the predetermined time, it can be notified that it is time to replace the filter assembly 6 (S23).

At this time, an alarm indicating that the replacement period of the filter assembly 6 has been completed may be made by illumination, sound, or the like provided on the humidifier 1, or may be displayed on the display unit. The manner of alarming that the replacement cycle of the filter assembly 6 has come is not limited to that described above.

24 is a flowchart of a self-cleaning mode of a humidifier according to an embodiment of the present invention.

Referring to FIG. 24, the humidifying device 1 according to one embodiment of the present invention may be provided to clean the humidifying pad 20 by itself. The operation mode of the humidification apparatus 1 may further include a self-clean mode in addition to the humidification mode. When performing the self-clean mode, the user can replace the water in the water tank 3 so that the cleaning of the humidification pad 20 can be performed by the clean water. In the self-clean mode, the fan assembly 6 does not operate, and the humidifying pad 20 can be cleaned by the water flowing through the humidifying pad 20.

When the self-clean mode of the humidification apparatus 1 is set (S30), the control unit can detect whether the humidification apparatus 1 is in a normal state in which the self-cleaning operation can be executed (S31). At this time, whether the state of the pump 5, the fan assembly 6 is normal, whether the humidifying pad 20, the water tank 3, etc. are properly installed or not can be detected. When the humidifier 1 is determined to be in an abnormal state, the self-clean mode can be terminated.

If it is determined that the humidifier 1 is in a normal state, the vent valve 317 may be opened (S32). By opening the vent valve 317, the pressure inside and outside of the supply passage 31 can be made equal. The vent valve 317 can be kept open for a predetermined time.

The control unit may detect whether the open time of the vent valve 317 has passed a preset time (S33). If it is determined that the open time of the vent valve 317 has passed the preset time, the vent valve 317 may be closed (S34) and the pump 5 may be operated (S35). The pump 5 can pump the water in the water tank 3 for a predetermined time. The pumped water may be fed to the humidification pad 20 through the filter assembly 4. The water supplied to the humidifying pad 20 can wash the humidifying pad 20 while flowing through the humidifying pad 20.

The pump 5 can be operated for a predetermined time so that the humidification pad 20 can be sufficiently cleaned. The control unit detects whether the operation time of the pump 5 has elapsed or not (S36). If it is determined that the predetermined time has passed, the controller 5 can stop the operation of the pump 5 (S37). As a result, the self-cleaning operation can be terminated.

When the self-cleaning operation is completed, the user can clean the humidifying pad 20 and replace the water recovered in the water tank 3 with fresh water.

As described above, since the humidification pad 20 can be cleaned while being mounted on the humidifier 1 without separating the humidification pad 20 from the humidifier 1, the convenience of the user can be improved.

This self-cleaning mode can be done manually or automatically. The humidification apparatus 1 may include a notification function for calculating the cumulative use time of the humidification pad 20 and displaying it so that the self-clean mode can be executed at predetermined intervals. The period required for the self-clean mode may be notified by illumination, sound, or display on the display unit. The user can operate the self-cleaning mode after confirming the notification. The self-clean mode may be automatically performed every predetermined period.

FIG. 25 is a flowchart of a corresponding mode for separating a water tank according to an embodiment of the present invention. FIG.

25, when the pump 5 is operated when the water tank 3 of the humidifier 1 according to the embodiment of the present invention is not properly installed, the vent valve 317 is opened for a predetermined period of time Respectively.

For example, the pump 5 or the fan assembly 6 may be kept running when the water tank 3 is forcibly disconnected during use of the humidifying device 1. [ In this case, the operation of the pump 5 or the fan assembly 6 is stopped and the vent valve 317 can be opened for a predetermined time.

Air can be introduced into the supply passage 31 by the pumping operation of the pump 5 when the pump 5 is operated with the water tray 3 separated. The water in the water tub 3 may not be pumped by the pump 5 due to the air introduced into the supply flow path 31 even if the water tub 3 is mounted later. Therefore, when the pump 5 is operated in a state where the water tray 3 is separated, the vent valve 317 may be opened for a predetermined time so that the air introduced into the supply passage 31 may be discharged.

Specifically, when the humidification mode is set (S40), the control unit can detect whether the water tub 3 is installed (S41). If it is detected that the water tank 3 is installed, the humidifying operation can be normally performed.

If it is detected that the water tank 3 is not mounted, the control unit detects whether the pump 5 is ON (S42). When the pump 5 is in the OFF state, the power of the fan assembly 6 is turned off (S48), and the humidification operation can be terminated. At this time, if the power of the fan assembly 6 is already off, the step of turning off the power of the fan assembly 6 may be omitted and the humidification operation may be terminated immediately.

The power of the pump 5 and the fan assembly 6 can be turned off when the water tray 3 is not mounted and the pump 5 is turned on (S43).

After the pump 5 and the fan assembly 6 are turned off, the vent valve 317 can be opened (S44). The vent valve 317 may be opened for a predetermined period of time. The control unit determines whether or not the vent valve 317 has been opened for a predetermined time in step S45. If it is determined that the vent valve 317 has passed the predetermined time, the vent valve 317 is closed in step S46. Thus, the operation when the pump 5 is operated in a state in which the water tank 3 is not mounted can be terminated.

The operation of the pump 5 in a state in which the water tank 3 of S40 to S48 is not mounted can be performed by the humidifier 1 while the water tank 3 is forcibly separated during operation of the humidifier 1.
