Description

Humidified air purifier {APPARATUS FOR PURIFYING AND HUMIDIFYING AIR}

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

A humidified air purifier sucks/filters indoor air, humidifies the filtered air, and discharges it back into the room. This humidified air purifier is provided with a water tank to contain water required for humidification.

Such a humidified air purifier needs to suppress the growth of microorganisms in the water tank due to hygiene problems, and for this purpose, the user can sterilize by putting a humidifier sterilizer separately purchased on the market into the water tank. However, this humidifier disinfectant contains ingredients that are harmful to the human body, which is a problem. In particular, among the components of conventional humidifier disinfectants, chilchloroisothiazolinone (CMIT) and methyl isothiazolinone (MIT) can cause fatal harm to the human body even in trace amounts. Several chemicals have the potential to cause unknown side effects.

Therefore, there is a need to provide a way to sterilize bacteria in the water tank without the use of 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 disinfectant.

Second, it is to provide a humidified air purifier in which the water tank is configured in a form that is detachable from the clean module, and the sterilization module is provided in the clean module.

Third, it is to provide a humidified air purifier that allows the ultraviolet rays emitted from the sterilization module to be more intensively irradiated into the 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 air sucked through the suction port, and a blowing unit for blowing air filtered by the filter.

A water tank is disposed in the clean module, and a transparent window is provided at the bottom of the water tank. A watering unit is provided for pumping water contained in the water tank and spraying water onto a flow path through which the air blown by the blowing unit is guided.

In order to sterilize water in the water tank, a sterilization module irradiating 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 clean module, the water tank can be separated from the clean module irrespective of the sterilization module, and therefore, the sterilization module does not become an obstacle when washing the water tank or replenishing water.

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

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.

A fixed frame 94 may be inserted inside the installation frame 434. The outer diameter of the fixing frame 94 is substantially the same as the inner diameter of the installation frame 434, and is fixed without shaking while the fixing frame 94 is fitted into the installation frame 434.

The fixing frame 94 may include a plate body 941 having an opening 94h formed at a position corresponding to the opening 431ah and a side plate 942 protruding upward from the circumference of the plate body 941. The plate body 941 may be formed in a rectangular shape, and the side plate 942 may extend upward from each side of the rectangular shape to form a rectangular shape.

The side plate 942 has one end connected to the plate body 941 and the other end corresponding to the opposite side. The portion enclosed by the other end is open, and the transparent window 93 is inserted into an area defined by the side plate 942 through the open portion.

The transparent window 93 may be formed in the shape of a plate made of a transparent material through which light (especially, ultraviolet rays) can pass. The transparent window 93 may have a shape substantially corresponding to a shape formed by the side plate 942 of the fixed frame 94. In this case, the circumference of the transparent window 93 is in close contact with the inner circumferential surface of the side plate 942, so that the transparent window 93 can be fixed without shaking in the fixing frame 94.

A frame cover 91 covering the fixed frame 94 may be further provided. An opening 91h may be formed in the frame cover 91 so that the light irradiated from the sterilization module 80 can be incident on the transparent window 93.

The frame cover 91 prevents the fixed frame 94 and the transparent window 93 from being separated from the installation frame 343, and covers the area limited by the side plate 942 on the bottom of the water tank base 431a. Can be combined. The frame cover 91 may be coupled to the water tank base 431a by fastening members such as screws or bolts.

The frame cover 91 may have at least one coupling mount 914 formed thereon. Each coupling mount 914 may be provided with a fastener 914h through which a fastening member such as a screw or bolt passes. The boss 437 may protrude from the bottom surface of the water tank base 431a at a position corresponding to the fastener 914h, and the fastening member may pass through the fastener 914h to be fastened with the boss 437.

In addition, a sealer 92 may be disposed between the frame cover 91 and the transparent window 93. The sealer 92 has a ring shape made of a flexible material, and is disposed so that the opening 91h is located inside. The sealer 92 is compressed by the transparent window 93, and thus, even if water penetrates into the fixed frame 94 through the opening 94h, it is prevented from reaching the opening 91h by the sealer 92 do.
