Description

Humidifying air purifier {APPARATUS FOR PURIFYING AND HUMIDIFYING AIR}

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

A humidified air purifier sucks/filters indoor air, humidifies the filtered air, and discharges it back into the room. Such a humidified air purifier is provided with a water tank for holding water necessary for humidification.

Such a humidified air purifier needs to suppress the growth of microorganisms in the water tank due to hygiene problems. However, these humidifier disinfectants contain components harmful to the human body, which is a problem. In particular, among the components of conventionally available humidifier disinfectants, chilchloroisothiazolinone (CMIT) and methylisothiazolinone (MIT) can cause fatal harm to the human body even in small amounts. Several chemicals have the potential to cause as yet unknown side effects.

Therefore, it is necessary to devise a method capable of sterilizing bacteria in a water tank without using a compound whose stability is not secured.

The problem to be solved by the present invention is, first, to provide a humidified air purifier capable of sterilizing microorganisms in a water tank using ultraviolet rays without using a separate sterilizing agent.

Second, to provide a humidified air purifier in which a water tank is configured to be separable from a cleaning module and a sterilization module is provided in the cleaning module.

Third, to provide a humidifying air purifier so that ultraviolet rays emitted from the sterilization module can be more intensively irradiated into the water tank.

The humidified air purifier of the present invention includes a cleaning module having a suction port through which air is sucked, a filter for filtering the air sucked through the suction port, and a blowing unit for blowing 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 pumping the water contained in the water tank and spraying the water onto a passage through which the air blown by the blowing unit is guided is provided.

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

The humidified air purifier of the present invention is harmless to the human body because it sterilizes the water tank using ultraviolet rays.

Second, since the sterilization module is provided in the cleaning module, the water tank can be separated from the cleaning module regardless of the sterilization module, and therefore, the sterilization module does not interfere at all when washing the water tank or replenishing water.

Third, since the ultraviolet rays emitted from the sterilization module and / or the ultraviolet rays incident on the water tank and totally reflected on the water surface and returned are reflected again by the reflecting surface, there is an effect of irradiating the ultraviolet rays into the water tank more intensively.

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

The power transmission unit 465 is for coupling the coupling shaft 466 with the rotating shaft of the water ring motor 27, and this coupling is detachable. That is, when the cleaning module 1 is mounted on the upper body 20, the rotation shaft of the watering motor 27 is coupled with the coupling shaft 466 by the power transmission unit 465, and the cleaning module 1 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 passes through the opening at the top of the column 435 and extends to the inside of the water ring housing 461. .

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

The watering housing cover 462 is coupled to the upper end of the watering housing 461 to close the opening at the top of the watering housing 461 .

In particular, 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 with the air flow and discharge humidifying medium disposed on the top cover 41 (to be described later) 44). Therefore, in the process of passing the air through the discharge humidifying medium 44, it contains moisture once again.

In addition, the water tank humidifying medium 49 installed in the water tank 43 can also be wetted by the 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.

Figure 17 is a top down view of the assembly of the inner visual body, water tank and watering unit. 18 shows a structure in which a transmission window is installed on the bottom of the water tank.

Referring to FIGS. 9 to 15 , a sterilization module 80 may be provided in the cleaning module 1 . The sterilization module 80 includes a light emitting unit 85 for emitting ultraviolet rays, a circuit board 81 on which the light emitting unit 85 is mounted, and a substrate holder 82 for fixing the circuit board 81 to the cleaning module 1. ), a transparent shield 83 disposed on the front surface of the substrate holder 82 through which ultraviolet light emitted from the light emitting unit 85 passes, and a shield holder coupled to the substrate holder 82 to fix 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 thereto, and may include other light emitting means such as an LCD or a lamp.

Hereinafter, the front and rear surfaces of the substrate holder 82 are respectively defined as a surface 821a facing the transparent shield 83 and a surface 821b corresponding to the opposite surface facing the circuit board 81. . The substrate holder 82 includes a substrate mounting plate 821 constituting the front surface 821a and the rear surface 821b, and a substrate installation rib 822 protruding from the rear surface 821b to define a space in which the circuit board 81 is installed. ) may be included. The substrate holder 82 may be made of a synthetic resin material.

The circuit board 81 may be fixed to the rear surface of the board 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 rear surface 821b of the substrate mounting plate 821, if the circuit board 81 is directly mounted on the rear surface 821b, it becomes difficult to install the circuit board 81 flat. Accordingly, the substrate supporter 824 protrudes from the rear surface 821b of the substrate mounting plate 821, and the circuit board 81 is flatly supported by the substrate supporter 824 without tilting to either side. A plurality of substrate supporters 824 may be formed. The substrate supporter 824 may extend along a substrate installation rib 822 to be described later.

Preferably, each curved section is formed between regions where straight sections are formed (P12, P23, P34, P41), and is in the form of an arc centered on a corner where adjacent straight sections meet each other. FIG. 14 is a cross section cut along the diagonal symmetrical reference line BB that passes through the corner and divides the areas P12 and P34 in which the spheres are formed. As in FIG. 13, the upper ends of the groove 827 are the first It can be seen that they 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 diagonal symmetric reference line B-B forms an angle of 45 degrees with the left-right symmetric reference line A-A. Such a structure is preferably common to all regions P12, P23, P34, and P41 in which curved sections are formed.

In this case, openings 431ah and 431bh through which light irradiated from the sterilization module 80 can pass are formed in the water tank base 431a and the water tank cover 431b, respectively, so that the water contained in the water tank 43 does not leak. Therefore, at least one of the openings 431ah and 431bh must be sealed.

In particular, the transparent window 93 may be installed in the opening 431ah formed in the water tank base 431a. An installation frame 434 may be formed on the bottom surface of the water tank base 431a to surround the opening 431ah.
