Second, it is an object of the present invention to provide a humidifying air purifier capable of accurately detecting the water level even when a small amount of water is contained in the water tank.

Third, it is an object of the present invention to provide a humidifying air cleaner capable of instantaneously detecting a change in water level in a water tank and accurately determining a water replenishment timing.

Fourth, the present invention provides a humidifying air purifier capable of detecting a water level in a water tank through a sensor disposed outside the water tank even when the water tank is separable.

The humidifying air purifier of the present invention sucks and blows air, filters the blown air, humidifies the air, and discharges the treated air. The humidifying air cleaner includes a water tank for containing water, a water ring unit for pumping water contained in the water tank and injecting the water from the inlet to the outlet for guiding air, and a water ring unit And a magnetic force sensor provided outside the water tank for sensing a magnetic field generated from the plotter.

Alternatively, the humidifying air cleaner of the present invention may include a clean module having an inlet through which air is introduced, a blower unit for blowing air introduced through the inlet, and a filter for filtering the air, And a humidification module connected to the clean module in a state where the humidifier module is detachably coupled to the clean module and connected to the clean module to introduce air from the clean module and to humidify the air and discharge the air through a discharge port, Wherein the humidification module comprises a water tank for storing water, a watering unit for pumping the water contained in the water tank and discharging the water from the suction port to the flow path for guiding air to the discharge port, And includes a plotter for generating a magnetic field. The clean module includes a water level sensor for sensing a magnetic field generated from the plotter.

The humidification module 4 may be detachably coupled to the upper body 20. [ The humidification module 4 may be inserted through the opening at the upper end of the outer visual body 22 and the water tub 43 may be disposed in the upper inner space 25. [ The water tub 43 may include a bottom 431a and a tubular side wall 431b extending upward from the bottom 431a.

The upper end of the side wall 431b may be coupled with the inner visual body 42. A plurality of connection portions 432 coupled to the inner visual body 42 are formed in the upper portion of the side wall 431b along the circumferential direction and open between the adjacent connection portions 432. The opening 43h between the connecting portions 432 can be formed at a position corresponding to the opening 25h formed in the upper inner 25. The air that has passed through the opening 25h of the upper inner 25 flows inward through the opening 43h of the water tub 43. [

The inner visual body 42 has a tubular shape extending vertically upwards and downwards, and may be formed of a transparent material. A water tank humidifying medium 49 may be coupled to the lower end of the inner visual body 42.

The power transmitting unit 465 is for coupling the coupling shaft 466 with the rotation shaft of the watering motor 27, and such a coupling is separable. That is, when the clean module 1 is mounted on the upper body 20, the rotation shaft of the water ring motor 27 is coupled to the engagement shaft 466 by the power transmission unit 465, When separated from the upper body 20, the coupling is released.

The power transmission unit 465 may be disposed in the column 435 of the water tank 43 and the coupling shaft 466 extends through the opening of the upper end of the column 435 to the inside of the water ring housing 461 .

The upper end of the water ring housing 461 may be coupled to the water ring housing cover 462 and the lower end of the water ring housing 461 may be engaged with the upper end of the positive housing 463 .

The water ring housing cover 462 is coupled to the upper end of the water ring housing 461 to close the opening of the upper end of the water ring housing 461.

On the inner surface of the positive housing 463, a groove 463a extending vertically downward may be formed. The grooves 463a may be formed to be spaced apart from each other along the circumferential direction. The opening of the lower end of the positive housing 463 is spaced apart from the bottom 431a of the water tray 43 so that water can flow in from the water tray 43. [ When the positive housing 463 is rotated, the water introduced into the inside of the positive housing 463 through the opening rises along the inner surface of the positive housing 463 due to the centrifugal force, and the groove 436a moves upward .

The water pumped by the positive housing 463 flows into the interior of the watering housing 461 and is continuously raised along the inner side of the watering housing 461 so that the water As shown in FIG. The sprayed water can form a water film in the form of droplets or spray in the inner visual body 42 to humidify the air. Particularly, since the air in the inner visual body 42 is being raised by the wind pressure provided by the blowing fan 121, the water particles rise together with the airflow, and the discharge humidifying medium 44). Therefore, once the air passes through the discharge humidifying medium 44, moisture is contained again.

The water tank humidifying medium 49 provided in the water tub 43 can also be wetted by the water jetted from the water ring housing 461 and the air guided by the flow guide 24 can be supplied to the water tank humidifying medium 49 It can contain moisture while passing through it.

The top cover 41 can be mounted on the inner visual body 42 and covers the open top of the inner visual body 42. The top cover 41 may be provided with a discharge port 411 for discharging air that has passed through the inner visual body 42 to the outside.

The water supply port 412 communicates with the inside of the water tank 43 so that the water supplied through the water supply port 412 is supplied into the water tank 43. Water can be poured into the water supply port 412 to fill the water tank 43 without separating the humidification module 4 from the clean module 1. [

The discharge humidification medium 44 may include a porous mesh 441 and a fixed frame 442 for fixing the mesh 441. The water molecules injected by the watering unit 46 rise together with the air stream passing through the inner visual body 42 so as to wet the mesh 441 so that the mesh is formed before the air is discharged through the discharge port 411 441).

A floater 60 may be provided in the water tank 43. The plotter 60 has a specific gravity smaller than that of water, so that when a certain portion or more of the plotter 60 is immersed in water, the floater 60 floats in the water, and accordingly, it floats in accordance with the level in the water tray 43.

A pair of guide ribs 433 and 434 for guiding the movement of the plotter 60 are formed in the side wall 431b of the water tub 43 in the vertical direction and the plotter 60 has guide ribs 433 and 434 .

The partition 80 is engaged with at least one guide rib 433 and 434 and defines a space in which the floater 60 is lifted and lowered in the water tub 43. [ The partition 80 is disposed substantially perpendicularly to the bottom 43a of the water tub 43 and has a partition wall portion 81 for partitioning the interior of the water tub 43 into a region for accommodating the floater 60 and other regions A pair of engagement ribs 83 projecting from the partition wall portion 81 and extending in the vertical direction and extending in the vertical direction so as to be laterally bent at the upper end of the partition wall portion 81, And the upper plate 85 abuts against the upper plate 85. As shown in Fig.

The fastening protrusions 433a and 434a are formed in one of the guide ribs 433 and 434 and the coupling ribs 83 and 84 and the fastening protrusion 87 is fastened to the fastening holes 433a and 434a . Hereinafter, it is assumed that the fastening holes 433a and 434a are formed in the guide ribs 433 and 434 and the fastening protrusion 87 is formed in the fastening ribs 83 and 84, respectively.

Two fastening holes 433a are formed in the first guide rib 433 and two fastening protrusions 87 are formed in the first fastening ribs 83 in correspondence thereto. Three fastening holes 434a are formed in the second guide rib 434 and two fastening protrusions 87 are formed in the second fastening ribs 84 correspondingly.

Guide ribs 433 and 434 are disposed between the first engaging rib 83 and the second engaging rib 84. The first engaging rib 83 is engaged with the first guide rib 433 on one side And the second engaging rib 84 may be formed on one side of the second guide rib 434 opposite to the second engaging rib 434. [ The first engaging rib 83 and the first guide rib 433 are closer to the height of the fastening protrusion 87 and the second engaging rib 84 is also close to the second guide rib 434. [ Therefore, interference may occur in the process of inserting the fastening protrusion 87 into the fastening holes 433a and 434a. However, since the partition 80 is made of a synthetic resin material, it has some elasticity, Even if interference occurs in the process of inserting the first and second engagement ribs 83 and 87 into the fastening holes 433a and 434a, (433a, 434a). After the fastening protrusions 87 are inserted into the fastening holes 433a and 434a, since the distance between the first fastening ribs 83 and the second fastening ribs 84 is restored as it is, Are not separated from the fastening holes 433a and 434a.

The partition 80 may further include at least one reinforcing rib 86 connecting one side of the engaging ribs 83 and 84 (opposite side of the surface on which the engaging projections 87 are formed) and the partitioning wall portion 81 have. The reinforcing ribs 86 are in the form of a horizontal plate, and connect between the engaging ribs 83 and 84 and the partition wall portion 81.

A water inlet 80a may be formed at the lower end of the partition wall portion 81. The water inlet 80a is in the form of an opened hole starting from the lower end of the partition wall portion 81 so that water is supplied from the bottom 431a of the water tank 43 outside the depression 431c (Hereinafter referred to as a floating chamber) between the partition 80 and the side wall 431b of the water tank 43 through the water inlet port 80a. That is, in the state in which the water tank 43 is empty, when the water supply is performed, the floating chamber immediately begins to be filled with water, and the depression 431c is filled first by the water introduced into the floating chamber.

The first engagement rib 83 and the second engagement rib 84 may be detachably coupled to the first guide rib 433 and the second guide rib 434, respectively. That is, at least one fastening protrusion 87 is formed on the first engaging rib 83 and the second engaging rib 84, and the fastening protrusion 87 is fastened to the fastening protrusion 87 formed on the guide ribs 433 and 434 433a, and 434a, whereby the partition 80 is fixed.

The pair of guide ribs 433 and 434 can be disposed between the first engaging rib 83 and the second engaging rib 84 and the outer surface of the first guide rib 433 can be disposed between the first engaging ribs 83 and the outer side surface of the second guide rib 434 faces the inner side surface of the second engaging rib 84.

 A depression 431c may be formed in the bottom 431a of the water tank 43. [ The depression 431c is configured such that at least a part of the plotter 60 can be received. At least a part of the floater 60 is located in the depression 431c in a state where the water tray 43 is empty and when water is supplied to the water tray 43 in this state, the depression 431c is first filled with water , The floater 60 floats in the process. In particular, it is preferable that the depth of the depression 431c is set so that the floater 60 floats before the water overflows the depression 431c. That is, when a certain portion of the plotter 60 is immersed in water in the process of filling water in the depression 431c, the floater 60 can be raised by buoyancy. Since the floater 60 has already floated in the water in the depression 431c, the water level of the floater 60 rises continuously as the water overflows the depression 431c.

If the depression 431c is not provided, the water tank 43 must be filled until buoyancy for floating the floater 60 is formed. Accordingly, water supply to the water tank 43 starts and the floater 60 is raised It takes time until it starts to become. Therefore, there is a problem that a predetermined amount of water is filled in the water tray 43 before the floater 60 is raised, but the water level at this time can not be measured using the plotter 60. [

On the other hand, in the present invention, it is sufficient that the water required to float the floater 60 is sufficient to fill the depression 431c, and the water level rise after the water overflows the depression 431c is referred to as a plotter 60 is also instantly performed, and the water level can be sensed more accurately by using the water level sensor 70 described later.

An upper opening 80b may be formed in the upper portion of the partition 80. [ In the embodiment, the upper opening 80b is partially formed in the partition wall portion 81 and the remaining portion is formed in the upper plate portion 85, but is not limited thereto.

As the water level in the floating chamber 80c is raised, air in the floating chamber 80c can be discharged through the upper opening 80b. That is, the upper opening 80b functions to vent the floating chamber 80c to the outside so that water can flow smoothly into the floating chamber 80c through the water inlet port 80a. In addition, And may serve as a water supply port for directly supplying water into the floating chamber 80c when supplying water into the water tank 43. [

The trough 88 may protrude from the periphery of the upper opening 80b. The trough 88 may protrude from the partition 81 to the inside of the floating chamber 80c. The trough 88 may include both sides 88a and 88b and a lower surface 88c connecting the lower ends of the sides 88a and 88b. And the opening portion 80b may be formed in the lower surface 88c. The opening 80b can extend from the edge of the lower surface 88c, that is, the opposite end of the portion connected to the partition 81. [

The plotter 60 generates a magnetic field (or magnetic force). Specifically, the plotter 60 may include a magnet 62, a plotter housing 61, and a plug 63. The plotter housing 61 is formed with a predetermined space in which the magnet 62 is received and an insertion port 61h through which the magnet 62 is inserted into the space. The cap 63 opens and closes the insertion port 61h of the plotter housing 61 and can be detachably coupled to the plotter housing 61. The magnet 62 is inserted into the plotter housing 61 through the insertion port 61h and then the insertion port 61h is inserted into the stopper 63 so that the assembling of the plotter 60 is completed.

In the embodiment, the magnet 62 may be disposed such that one of the N pole and the S pole faces the insertion port 61h of the plotter housing 61, and the other is directed to the opposite side.

Since the conventional synthetic resin material has a specific gravity larger than that of water, in order to allow the floater 60 to float in the water, the inside of the plotter housing 61 is filled with the magnet It is preferable that a cavity is further formed in addition to the space in which the first and second electrodes 62 and 62 are accommodated.

The water level sensor 70 senses the magnetic field generated from the floater 60 and can detect the position of the floater 60 or sense the displacement based on the detected magnetic field. The water level in the water tank 43 can be determined based on the output value of the water level sensor 70 since the position of the floater 60 varies with the water level in the water tank 43. [

The water level sensor 70 may be provided on the outer side of the water tank 43, and is preferably disposed on the upper body 20. More specifically, the sensor housing 26 can be coupled to the outer side of the side wall 25b of the upper inner 25, and the water level sensor 70 can be fixedly disposed inside the sensor housing 26.

The sensor housing 26 includes a rear housing 261 coupled to the side wall 25b of the upper inner 25 and having a front opening so that the water level sensor 70 can be inserted therein, And a front housing 262 that shields the front housing 262.

The water level sensor 70 includes a circuit board 78 and at least one hall sensor 71-75 mounted on the circuit board 78 and a circuit board 78 connected to the sensor housing 26 via a power supply Terminal and / or the communication terminal.

The Hall sensors 71 to 75 sense the strength of the magnetic field and output a signal, and the controller (not shown) can determine the water level based on the signal thus outputted. The controller may include a microprocessor which is electrically connected to the Hall sensors 71-75 and processes a signal applied from the Hall sensors 71-75 to determine a water level.

The plurality of hall sensors 71-75 are preferably arranged in the vertical direction and at least one of the floaters 60 outputs signals according to the height of the floaters 60. The control unit controls the hall sensors 71-75 And the water level can be determined.

On the other hand, the humidifying air cleaner may include an acoustic output device such as a buzzer, a speaker, and a visual display device such as an LCD / LED.
