Description

Humidifying air purifier{APPARATUS FOR PURIFYING AND HUMIDIFYING AIR}

The present invention relates to a humidifying air purifier with a humidifying function and an air purifying function.

A humidifying air purifier sucks/filtrates indoor air, humidifies the filtered air, and discharges it back into the room. This humidifying air purifier is equipped with a water tank to contain the water needed for humidification.

These humidified air purifiers need to suppress the growth of microorganisms in the water tank due to hygiene issues, and for this purpose, users can sterilize the water tank by putting a humidifier sterilizer purchased separately on the market into the water tank. However, these humidifier disinfectants are problematic because they contain ingredients harmful to the human body. In particular, among the ingredients of commercially available humidifier disinfectants, chilchloroisothiazolinone (CMIT) and methylisothiazolinone (MIT) can cause fatal harm to the human body even in trace amounts, and in addition, humidifier disinfectants contain Many chemicals have the potential to cause as yet unknown side effects.

Therefore, there is a need to come up with a method to sterilize bacteria in a water tank without using compounds whose stability is not guaranteed.

The problem to be solved by the present invention is, first, to provide a humidifying air purifier that can sterilize microorganisms in a water tank using ultraviolet rays without using a separate sterilant.

Second, to provide a humidifying air purifier in which the water tank is configured to be separable from the cleaning module, and the cleaning module is equipped with a sterilizing module.

Third, it provides a humidifying air purifier that allows ultraviolet rays emitted from the sterilization module to be more intensively irradiated into the water tank.

The humidifying air purifier of the present invention includes a cleaning module having an intake port through which air is sucked, a filter that filters the air sucked through the intake port, and a blowing unit that blows the air filtered by the filter.

A water tank is disposed within the cleaning module, and a transparent window is provided at the bottom of the water tank. A watering unit is provided that pumps the water contained in the water tank and sprays the water onto a passage through which the air blown by the blowing unit is guided.

In order to sterilize the water in the water tank, a sterilizing module that irradiates ultraviolet rays into the water tank may be provided in the cleaning module.

Since the humidifying air purifier of the present invention sterilizes the water tank using ultraviolet rays, it is harmless to the human body.

Second, because the cleaning module is equipped with a sterilizing module, the water tank can be separated from the cleaning module regardless of the sterilizing module, and therefore, the sterilizing module does not become an obstacle at all when cleaning or replenishing water in the water tank.

Third, since the ultraviolet rays emitted from the sterilization module and/or the ultraviolet rays that enter the water tank and return after being totally reflected by the water surface are re-reflected by the reflective surface, there is an effect of irradiating ultraviolet rays into the tank more intensively.

Fourth, forming a plurality of grooves parallel to each other on the reflective surface has the effect of increasing the reflection efficiency of ultraviolet rays.

The humidifying air purifier according to an embodiment of the present invention is a flow path that guides air from the intake port 111 through which air is sucked to the discharge port 411 through which filtered and humidified air is discharged (the airflow indicated by the thick arrow in FIG. 4 moves). path) is formed. A blowing unit 12 is provided to form an airflow along the flow path, and may include a watering unit 46 that sprays atomized water in the form of droplets or spray onto the flow path.

At least one humidifying medium (44, 49) may be provided on the flow path. The humidifying media 44 and 49 may be wetted directly by water sprayed from the watering unit 46 or by moisture contained in the airflow. The air flowing along the passage directly carries water sprayed from the watering unit 46, but also absorbs moisture while passing through the humidifying media 44 and 49.

Hereinafter, the configurations of the humidifying air purifier according to an embodiment of the present invention will be described in more detail.

The humidifying air purifier may include a cleaning module (1) that filters air, and a humidifying module (4) that humidifies the air filtered by the cleaning module (1). The humidifying module (4) can be detachably coupled to the cleaning module (1). Preferably, the cleaning module (1) is placed on the indoor floor, and the humidifying module (4) is mounted on top of the cleaning module (1).

The cleaning module (1) filters the air sucked in through the intake port (111) and blows it to the humidifying module (4). The cleaning module (1) is mounted on the indoor floor of a living room, etc. and includes a lower body (10) with an intake port (111), and a filter assembly (10) installed on the lower body (10) and filtering the air introduced through the intake port (111). 30) and an upper body 20 that is mounted on the upper side of the lower body 10 and into which air filtered from the lower body 10 flows.

The lower body 10 may include a lower body main body 11 in which an intake port 111 through which air is sucked is formed. The intake port 111 is formed in the lower part of the lower body main body 11, and may be formed in a ring shape so that air can be sucked in from any direction.

A flow path through which air introduced through the intake port 111 is guided may be formed in the lower body main body 11, and the air is filtered by the filter assembly 30 while being guided along the flow path. The filter assembly 30 may include a filter 31 that filters air, and a filter tray 32 that accommodates the filter 31.

The filter assembly 30 may be detachably provided on the lower body main body 11. The lower body main body 11 has an insertion hole formed on the side into which the filter tray 32 is inserted, and the filter tray 32 can be moved laterally to be inserted into the insertion hole or pulled out from the insertion hole. After separating the filter assembly 30 from the lower body main body 11, the user can replace or clean the filter 31 by taking it out from the filter tray 32.

A blowing unit 12 may be provided within the lower body main body 11. The blowing unit 12 may be disposed above the filter assembly 30. The blowing unit 12 may include a blowing fan 121 and a blowing motor 122 that rotates the blowing fan 121.

The blowing fan 121 is a centrifugal fan, and in the embodiment, it is a turbo fan, but is not necessarily limited thereto. The turbofan 121 is provided between a shroud (121a) with a fan intake port through which air is sucked, a main plate (121b) coupled to the rotation axis of the blower motor 122, and the shroud (121a) and the main plate (121b). It may include a plurality of blades 121c. Air sucked in in the axial direction (a direction extending along the rotation center of the blowing fan 121) through the fan intake port of the shroud 121a is discharged laterally through between the blades 121c.

As shown in FIG. 4, the blowing fan 121 may be disposed below the blowing motor 122 so that the blowing fan 121 can suck in air from the lower side. A flow path of an appropriate shape may be formed within the lower body main body 11 to guide air discharged laterally by the blowing fan 121 upward.

An opening is formed on the upper side of the lower body main body 11, and air blown by the blowing fan 121 is discharged through the opening. The upper body 20 is installed in the opening, and air discharged through the opening flows into the upper body 20.

The upper body 20 may be detachably coupled to the lower body 10. The upper body 20 may include an upper outer 21, an outer visual body 22, an upper inner 25, and a flow guide 24.

The upper outer 21 has a cylindrical appearance with openings at the top and bottom, and an upper inner 25 that accommodates a water tank 43, which will be described later, may be provided inside the upper outer 21. The lower end of the upper inner 25 protrudes further downward than the upper outer 21 and is inserted into the upper opening of the lower body main body 11. In this state, the lower end of the upper outer 21 is lower than the upper outer body 11. ) is in contact with the perimeter of the upper opening.

The outer visual body (22) is coupled to the upper part of the upper outer (21). The outer visual body 22 has a tubular shape that is long up and down, and may be made of a transparent material.

The flow guide 24 guides the flow of air inside the upper outer 21 and may be formed to surround the outside of the upper inner 25. Air introduced from the lower body 10 is guided upward along the flow guide 24.

The upper inner 25 includes a bottom 25a and a tubular side wall 25b extending upward from the bottom 25a, through which air guided along the flow guide 24 passes. At least one opening 25h1 may be formed. A water tank humidifying medium 49 may be disposed within the upper inner 25. The air flowing into the upper inner 25 through the opening 25h1 passes through the water tank humidifying medium 49. As will be described in more detail later, the water sprayed by the watering unit 46 is absorbed into the water tank humidifying medium 49, and therefore, the air retains moisture in the process of passing through the water tank humidifying medium 49.

The humidification module 4 may include an inner visual body 42, a water tank 43, a watering unit 46, and/or a top cover 41.

The humidification module 4 humidifies the air by spraying water into the air flow path. The water tank 43 contains water used for humidification, and the watering unit 46 pumps the water in the water tank 43 and sprays it.

Referring to FIG. 7, a floater 73 that is raised and lowered depending on the water level may be provided in the water tank 43. A partition 72 may be provided to partition the inside of the water tank 43, and the floater 73 may be placed in a space limited by the partition 72.

The floater 73 has a specific gravity smaller than that of water, so when a certain portion or more of the floater is immersed in water, it floats, and thus rises and falls depending on the water level in the water tank 43. The floater 73 floats by buoyancy within the water tank 43, and therefore, the position (or height) of the floater 73 varies depending on the water level within the water tank 43.

The plotter 73 may include a magnet (not shown). A water level sensor (not shown) that detects the magnetic field (or magnetic force) generated from the magnet may be installed on the outside of the water tank 43. The water level sensor can output a current or voltage signal depending on the size of the detected magnetic field.

The humidification module 4 may be detachably coupled to the upper body 20. The humidifying module 4 may be inserted through an opening at the top of the outer visual body 22, and the water tank 43 may be placed within the upper inner 25. The water tank 43 may include a water tank base 431a and a tubular side wall 43b extending upward from the water tank base 431a.

The top of the side wall (43b) may be combined with the inner visual body (42). On the upper part of the side wall 431b, a plurality of connection parts 432 coupled to the inner visual body 42 are formed spaced apart along the circumferential direction, and there is an opening between adjacent connection parts 432. The opening 43h between the connecting portions 432 may be formed at a position corresponding to the opening 25h1 formed in the upper inner 25. Air that has passed through the opening 25h1 of the upper inner 25 flows inward through the opening 43h of the water tank 43.

The inner visual body 42 has a tubular shape extending vertically and may be made of a transparent material. A water tank humidifying medium 49 may be coupled to the lower part of the inner visual body 42. The water tank humidifying medium 49 may include a porous mesh (not shown) capable of absorbing moisture, and a fixing frame for fixing the mesh.

The watering unit 46 may include a watering housing 461, a watering housing cover 462, a pumping housing 463, a coupling shaft 466, and a power transmission unit 465.

A watering motor 27 that drives the watering unit 46 may be provided on the bottom of the bottom 25a of the upper inner 25. The power transmission unit 465 is for coupling the coupling shaft 466 with the rotation shaft of the watering motor 27, and this coupling is separable. That is, when the humidification module 4 is mounted on the upper body 20, the rotation axis of the watering motor 27 is coupled to the coupling shaft 466 by the power transmission unit 465, and the humidification module 4 is coupled to the coupling shaft 466. Upon separation from the upper body 20, the coupling is released.

The power transmission unit 465 may be disposed within the column 435 of the water tank 43, and the coupling shaft 466 passes through the opening at the top of the column 435 and extends to the inside of the watering housing 461. .

The watering housing 461 has a tubular shape (preferably cylindrical) with the upper and lower ends open, and the upper end is coupled with the watering housing cover 462, and the lower end can be coupled with the upper end of the positive housing 463. .

The watering housing cover 462 is coupled to the upper part of the watering housing 461 and can close the opening at the upper end of the watering housing 461. The watering housing cover 462 is coupled to the coupling shaft 466, and therefore, when the coupling shaft 466 is rotated, the watering housing cover 462, the watering housing 461, and the positive housing 463 are integrated. is rotated. A plurality of blades 461a may protrude from the outer peripheral surface of the watering housing 461.

The positive housing 463 may have a circular horizontal cross section. The positive housing 463 may be formed in a funnel shape where the size of the horizontal cross-section gradually increases toward the top.

A groove 463a extending vertically may be formed on the inner surface of the positive housing 463. A plurality of grooves 463a may be formed to be spaced apart from each other along the circumferential direction. The opening at the bottom of the pumping housing 463 is spaced apart from the water tank base 341a of the water tank 43 to allow water to flow in from the water tank 43. When the pumping housing 463 is rotated, the water flowing into the pumping housing 463 through the opening rises along the inner surface of the pumping housing 463 by centrifugal force, and the groove 436a allows this water to rise. further promotes

The water pumped by the pumping housing 463 flows into the inside of the watering housing 461 and continues to rise along the inner surface of the watering housing 461, forming a spray hole 461h in the watering housing 461. It can be sprayed outward through. The water sprayed in this way can humidify the air by forming a water film in the form of droplets or spray within the inner visual body 42. In particular, since the air within the inner visual body 42 is being raised by the wind pressure provided by the blowing fan 121, the water particles rise with the airflow and are discharged to the humidifying medium disposed on the top cover 41 (described later) 44) is soaked. Therefore, as the air passes through the discharge humidifying medium 44, it once again contains moisture.

In addition, the water tank humidifying medium 49 installed in the water tank 43 can also be wetted by water sprayed from the watering housing 461, and the air guided by the flow guide 24 moves the water tank humidifying medium 49. It may contain moisture as it passes through.

The top cover 41 can be mounted on the inner visual body 42 and covers the open top of the inner visual body 42. A discharge port 411 may be formed in the top cover 41 to discharge air that has passed through the inner visual body 42 to the outside.

The top cover 41 is installed on a cover frame 410 with a water inlet 412 formed approximately in the center and a plurality of discharge ports 411 along the circumference of the water inlet 412, and on the cover frame 410. , It may include a discharge humidifying medium 44 that is disposed below the discharge port 411 and humidifies the air flowing through the discharge port 411.

The water supply port 412 is in communication with the inside of the water tank 43, and therefore, water supplied through the water supply port 412 is supplied into the water tank 43. The water tank 43 can be filled by pouring water into the water supply port 412 without separating the humidifying module 4 from the cleaning module 1.

The discharge humidifying medium 44 may include a porous mesh 441 and a fixing frame 442 for fixing the mesh 441. The water molecules sprayed by the watering unit 46 rise with the airflow passing through the inner visual body 42 and wet the mesh 441, and thus, before the air is discharged through the discharge port 411, the mesh ( 441) has a humidifying effect upon contact with it.

Meanwhile, in the embodiment, the lower body 10, the upper body 20, and the humidification module 4 are separably coupled to each other. At least one of these components is provided with a power supply device that supplies power, and the other components are provided with a power terminal that is electrically connected to the power supply device while these components are combined with each other, thereby providing power to the electrical components. This can be supplied.

For example, when the lower body 10 is provided with a power supply, the upper body 20 and the humidification module 4 may be provided with a power terminal. In particular, the upper body 20 can mediate the power applied from the lower body 10 to be supplied to the humidification module 4.

In addition, one of the lower body 10, the upper body 20, and the humidification module 4 is provided with a control unit, and the others have a communication terminal that is connected to the control unit to enable communication while the above components are combined with each other. It can be provided.

Figure 11 is a perspective view showing a substrate holder. FIG. 12 is a plan view of the substrate holder shown in FIG. 11. Figure 13 is a cross-sectional view taken along A-A in Figure 12. Figure 14 is a cross-sectional view taken along B-B in Figure 12. Figure 15 is a view from above of the interior of the upper inner. Figure 16 is an exploded perspective view of the water tank. Figure 17 is a top view of the assembly of the inner visual body, water tank, and watering unit. Figure 18 shows a structure in which a transparent window is installed on the bottom of the water tank.

Referring to FIGS. 9 to 15, the cleaning module 1 may be equipped with a sterilizing module 80. The sterilizing module 80 includes a light emitting unit 85 that emits ultraviolet rays, a circuit board 81 on which the light emitting unit 85 is mounted, and a substrate holder 82 that secures the circuit board 81 to the cleaning module 1. ) and a transparent shield 83 disposed on the front of the substrate holder 82 through which ultraviolet rays emitted from the light emitting unit 85 transmit, and a shield holder coupled to the substrate holder 82 and fixing the transparent shield 83. (84) may be included.

The light emitting unit 85 irradiates ultraviolet rays and preferably includes an LED chip, but is not limited to this and may be provided with other light emitting means such as an LCD or a lamp.

Hereinafter, the front and back sides of the substrate holder 82 are defined as a surface 821a facing the transparent shield 83 and a surface 821b facing the circuit board 81 as the opposite side, respectively. . The substrate holder 82 includes a substrate installation plate 821 constituting the front surface 821a and the rear surface 821b, and a substrate installation rib 822 that protrudes from the rear surface 821b and defines the space where the circuit board 81 is installed. ) may include. The substrate holder 82 may be made of synthetic resin.

The circuit board 81 may be fixed to the back of the board installation plate 821. A through hole 82h through which the light emitting portion 85 passes is formed in the substrate mounting plate 821 so that the light emitting portion 85 mounted on the circuit board 81 can be exposed to the front side of the substrate mounting plate 821. It can be.

At least a portion of the rear surface of the substrate mounting plate 821 forms a convex portion toward the circuit board 81, and correspondingly, the front surface 821a of the substrate mounting plate 821 has a concave portion inclined toward the through hole 82h. A reflective surface 825 may be formed.

Since a convex portion is formed on the back surface 821b of the board installation plate 821, if the circuit board 81 is mounted directly on the back surface 821b, it becomes difficult to install the circuit board 81 flatly. Accordingly, the substrate supporter 824 protrudes from the back surface 821b of the substrate mounting plate 821, and the circuit board 81 is supported flatly without being tilted to one side by the substrate supporter 824. A plurality of substrate supports 824 may be formed. The substrate supporter 824 may extend long along the substrate installation rib 822, which will be described later.

The board installation rib 822 may extend to surround the circuit board 81. The board installation rib 822 may not completely surround the circuit board 81 and may be partially open. As in the embodiment, when the circuit board 81 has a square shape, the board installation rib 822 may extend along three sides of the square except for one of the four sides.

A lock 826 may be formed on the board installation rib 822 to secure the circuit board 81 mounted on the board supporter 824. The lock 826 may protrude from the board installation rib 822 and restrains the circuit board 81 located inside the board installation rib 822. That is, the circuit board 81 is prevented from moving in the lateral direction by the board installation rib 822, and while the bottom surface is supported by the board supporter 824, the upper surface interferes with the lock 826, thereby moving up and down. Movement in that direction is impeded.

Referring to FIG. 11, a reflective surface that reflects ultraviolet rays may be formed on the front surface 821a of the substrate holder 82. To improve light reflectance, the front surface 821a of the substrate holder 82 may be configured to have a metallic luster. The front surface 821a, which has a metallic luster (preferably silver), is formed by depositing metal on the surface of the substrate holder 82 made of synthetic resin, coloring a metallic paint, or applying a metallic colored film. It can be implemented in various ways, such as:

Meanwhile, a plurality of grooves 827 extending in parallel and surrounding the through hole 82h may be formed on the front surface 821a of the substrate holder 82. A plurality of grooves 827 may extend parallel to each other. The inner surface of the groove 817 may also be treated to have a metallic luster.

The grooves 827 may each be formed in an annular shape with a common center. Here, the “ring shape” does not necessarily have to be a perfect circle, and a closed loop shape surrounding the through hole 82h is sufficient.

Each groove 827 may form an orthogonally symmetrical pattern, and as shown in FIGS. 12 and 13, in a cross section where the center of symmetry is cut with the left-right symmetric reference line (A-A), the grooves 827 The upper end may be aligned on the first line segment PL1 inclined at a constant angle with respect to the horizontal, and the lowest points of the grooves 827 may be aligned on the second line segment PL2 parallel to the first line segment PL1. Although not shown, this structure is the same even when the substrate holder 82 is cut along a straight line that passes through the center of symmetry and is perpendicular to A-A.

Meanwhile, the front surface 821a of the substrate holder 82 is divided into regions P1, P2, P3, and P4 that have a constant width and extend in four directions and are arranged symmetrically to each other, and these regions (P1, P2, P3). , P4), the groove 827 connects the straight sections formed on the areas (P1, P2, P3, P4) and the straight sections. And, it may include curved sections that form an arc with a constant radius centered at the concentric center.

Preferably, each curved section is formed between the areas where the straight sections are formed (P12, P23, P34, and P41), and is in the form of an arc centered on the corner where adjacent straight sections meet each other. Figure 14 is a cross-section cut along the diagonally symmetric reference line (B-B) bisecting the area (P12, P34) where the curved section is formed passing through the edge. As in Figure 13, the tops of the grooves 827 are at the first angle with respect to the horizontal. It can be seen that the grooves 827 are aligned on the third line segment PL3 inclined at the same angle as the line segment PL1, and the lowest points of the grooves 827 are aligned on the fourth line segment PL4 parallel to the third line segment PL3. Here, the diagonally symmetric reference line (B-B) forms a 45-degree angle with the left-right symmetric reference line (A-A). This structure is preferably common to all areas (P12, P23, P34, and P41) where curved sections are formed.

The through hole 82h may be substantially square, and each of the four-way extending areas P1, P2, P3, and P4 may extend outward from each side of the square, and each area where a straight section is formed ( The width of P1, P2, P3, P4) is substantially equal to the length of one side of the square.

An opening 25h2 through which light emitted from the light emitting unit 85 can pass may be formed at the bottom 25a of the upper inner 25. A sterilization module 80 may be placed on the bottom 25a of the upper inner 25. A sterilizing module installation frame 251 may be formed on the bottom of the upper inner 25 (i.e., the bottom of the floor 25a) to surround the opening 25h. The sterilization module installation frame 251 may be formed in the form of a rib protruding from the bottom of the upper inner 25.

A shield holder 84 may be inserted inside the sterilization module installation frame 251. The outer diameter of the shield holder 84 is substantially the same as the inner diameter of the sterilizing module installation frame 251, so that the shield holder 84 is fixed without shaking when inserted into the sterilizing module installation frame 251.

The shield holder 84 includes a plate body 841 having an opening 84h formed at a position corresponding to the opening 25h2 (or a position corresponding to a transparent window 93 to be described later), and an upper side from the periphery of the plate body 841. It may include a side plate 842 protruding. The plate body 841 may have a rectangular shape, and the side plate 842 may extend upward from each side of the rectangle to form a rectangular shape. Ultraviolet rays emitted from the light emitting unit 85 pass through the transparent shield 83 and enter the transparent window 93 provided at the bottom of the water tank 43.

The side plate 842 has one end connected to the plate body 841 and the other end opposite to it. The portion surrounded by the other end is open, and the transparent shield 83 is inserted into the area defined by the side plate 842 through the open portion.

The transparent shield 83 may be formed in the form of a plate made of a transparent material that allows light (particularly, ultraviolet rays) to pass through. The shape of the transparent shield 83 may substantially correspond to the shape of the side plate 842 of the shield holder 84. In this case, the periphery of the transparent shield 83 is in close contact with the inner peripheral surface of the side plate 842, so that the transparent shield 83 can be fixed without shaking within the shield holder 84.

Shield holder 84 may be covered by substrate holder 82. The substrate holder 82 prevents the sterilization module installation frame 251 and the transparent shield 83 from being separated from the shield holder 84, and covers the area limited by the side plate 842 of the upper inner 25. Can be joined to the bottom.

At least one coupling mount 823 may be formed on the substrate holder 82 to protrude to the outside of the substrate installation plate 821. A fastener 823h through which a fastening member such as a screw or bolt passes may be formed in each coupling mount 823. A boss 255 may protrude from the bottom of the upper inner 25 at a position corresponding to the fastener 823h, and the fastening member may pass through the fastener 823h and be fastened to the boss 255.
Meanwhile, referring to FIGS. 11 to 14, a protruding rib R may be formed on the front surface 821a of the substrate holder 82, protruding from the front surface 821a and extending to surround the reflective surface 825. there is.
