Ceiling type UV sterilizer {ULTRAVIOLET AIR STERILIZER}

The present invention relates to an ultraviolet sterilizer installed on the ceiling to obtain an air sterilization effect of purifying the air by removing bacteria and odors in the air and an effect of indoor indirect lighting at the same time, and more specifically, it is directly installed on the finishing surface of the ceiling indoors. It is about a ceiling-type UVC sterilizer that can reduce the time and effort required for installation and can be easily and safely installed by a worker alone.

In general, an ultraviolet sterilizer can sterilize bacteria, viruses, and various pathogenic microorganisms present in the air by irradiating ultraviolet rays to the air therein while flowing indoor air.

In particular, UVC, a type of short-wavelength ultraviolet rays, is known to have an effect of strongly sterilizing viruses and bacteria. In this regard, the Spectrum Journal published by the Institute of Electrical and Electronics Engineers (IEEE) published the research results of researchers at Columbia University in the United States that UV rays with short wavelengths can effectively remove viruses such as Corona 19 in the air without harming the human body. there is a bar

Recently, an air sterilizer that can obtain a virus sterilization function using UVC is in the limelight.

For example, Patent Document 1 discloses an air circulation type ultraviolet air sterilizer mounted on the ceiling of a space to which air sterilization is applied and sterilizing germs in the air flowing into the interior using ultraviolet rays while circulating air floating in the target space.

Referring to FIG. 1, this includes a lower housing 111 that sucks in air from the bottom and flows upward, and an upper housing 112 mounted on top of the lower housing 111 to flow the air transferred upward to the side. An air circulation unit 110 including an air circulation unit 110, an air sterilization unit 120 mounted on the inner surface of the lower housing 111 and irradiating ultraviolet rays into the inner space of the lower housing 111, mounted on the lower surface of the lower housing 111 a state output unit 130 that detects the state of air drawn into the lower housing 111 and transmits detection data to the control unit 140 and outputs a visual signal according to the control signal received from the control unit 140; Based on the data mounted on one side of the upper housing 112 and received from the status output unit 130, the air circulation unit 110, the air sterilization unit 120, and the status output unit 130 are controlled, and the current sensor A control unit 140 that calculates the replacement time of the ultraviolet lamp 122 based on the data detected through and transmits a control signal to output a visual signal to the status output unit 130 when the replacement of the ultraviolet lamp 122 is required, and It is mounted on the upper part of the air circulation unit 110 and supplies power to the air circulation unit 110, the air sterilization unit 120, the status output unit 130 and the control unit 140, and is provided in the air sterilization unit 120. It consists of a power supply unit 150 including a current sensor for detecting the amount of current applied to the UV lamp 122.

However, this is inconvenient to use due to the operating noise of the air flow fan 116 and the motor 117 that suck air from the bottom of the lower housing 111 and flow it upward, and the noise generated during the forced flow of air. There is a problem in that the use is limited in a quiet indoor space.

In addition, in order to directly install the air sterilizer 100 on the ceiling surface, first take out the wire wired to the ceiling, cut it to an appropriate length, peel off the sheath, and then, while one worker is holding the air sterilizer 100, another worker 1 The power supply unit 150 attached to the upper surface (the surface facing the ceiling), that is, the PSU (a power supply device consisting of a constant current circuit for converting high voltage alternating current into low voltage direct current and supplying constant current to LEDs) (Power Supply Unit)}, the installation is quite inconvenient and difficult because it is necessary to fix it to the ceiling by driving screws, etc. one by one while keeping the top in close contact with the ceiling surface, as well as requiring two or more workers. The convenience and efficiency of work are inevitably reduced when installing on the ceiling surface, such as an increase in installation cost due to the burden of labor costs.

In particular, in the case of houses such as apartments, since the ceiling finish surface is made of gypsum board with weak bearing capacity, first of all, the air sterilizer (100) must be accurately fixed to the ceiling in advance, anchored for gypsum, and then fixed to the ceiling finish surface using screws. However, there is a very difficult and difficult problem in holding the heavy air sterilizer 100 and accurately setting the driving position of the plaster anchor on the wide ceiling finishing surface.

In addition, in the case of a general house in which the ceiling finish surface is usually finished with a single plywood, the installation process is very complicated and inconvenient, such as the need to damage the intact ceiling finish surface, and there is a problem in that it takes a lot of work.

Moreover, during inspection or maintenance of the air sterilizer 100, there is a problem in that the screws are individually unscrewed and then re-tightened, which is cumbersome and inconvenient.

The background art or prior art described above herein is information possessed by the present inventor or acquired in the process of deriving the present invention, and is only intended to help understand the technical significance of the present invention, prior to the filing of the present invention, the technology to which this invention belongs It is revealed that it does not mean widely known technology in the field, and reference numerals in the prior art are irrelevant to the reference numerals in the present invention.

Therefore, a single worker can easily, conveniently, and safely install it on the ceiling surface, reducing the fatigue of installation work and improving convenience and efficiency. In addition, it can shorten the time required for installation and significantly reduce installation manpower and costs (labor costs). there is.

Moreover, even if the main body maintains the installed state on the ceiling surface with the magnetic force of the magnet, and then overcomes the magnetic force (attractive force) between the magnet and the bracket due to its own weight or external force and is separated from the bracket, the latch is secondarily caught on the bracket, preventing it from falling due to gravity from the ceiling. It can be prevented.

Furthermore, since the main body's latch passes through the guide hole of the bracket, the attractive force between the magnet and the bracket acts, and the entire body is slid and moved by the guide of the slider and the mount hole. It is possible to easily and naturally match the positions of the guide hole and the latch, which are hidden by the lower surface and are not visible, so that a single worker can simply and easily install them in the correct position on the ceiling.

In addition, a plurality of ventilation holes 12 are formed on the side surface (side wall portion) of the main body 10 to radiate ultraviolet rays (light) generated from the internal sterilization module 11 to the outside and to allow air to pass through.

That is, air enters and exits the internal space of the main body 10 through the ventilation hole 12 by natural convection, and at this time, bacteria or viruses contained in the air are sterilized by short-wavelength ultraviolet rays irradiated from the sterilization module 11. and odor removal function.

In addition, short-wavelength ultraviolet rays irradiated by the sterilization module 11 are radiated only sideways through the ventilation hole 12 .

In addition, the main body 10 is made of an opaque material so that the short-wavelength ultraviolet rays irradiated by the sterilization module 11 are not exposed to the outside, and is formed in a form to accommodate the sterilization module 11 as if it were wrapped around it.

That is, short-wavelength ultraviolet rays are not exposed or irradiated to the lower portion of the main body 10, so that effects on the human body and side effects can be minimized.

In addition, since the light generated from the sterilization module 11 is radiated to the outside through the ventilation hole 12, an indirect lighting effect that creates a mild indoor atmosphere with soft light and less glare can be obtained.

And, at the bottom of the main body 10, a fitting jaw 13 inserted into the inner space of the rim of the upper surface of the shield cover 40 is formed to protrude downward.

In addition, the air circulation unit may perform a heat dissipation function of discharging heat generated inside the main body 10 .

In addition, the sterilization module 11 may include a substrate mounted with a plurality of UVC LED lamps that emit harmless deep ultraviolet rays (short wavelengths in the range of 100 to 290 nm) when power is supplied, or may include a mercury lamp that emits ultraviolet rays. .

For example, the sterilization module 11 may have a structure in which electrodes are installed at both ends of a transparent quartz tube, and both ends are sealed in a state in which mercury, a metal halide additive, and an inert buffer gas are filled therein.

In this case, when a high-purity quartz tube having an SiO2 content of about 99.97% or more is applied, ultraviolet rays in the 253.7 nm wavelength band having excellent sterilizing power can be effectively emitted.

In addition, the sterilization module 11 is configured to include a converter, so that AC power applied from commercial power is converted into DC power by the converter and output, and thus the sterilization module 11 is driven to generate ultraviolet rays.

On the other hand, the lower surface of the main body 10 may be made of a magnetic material such as iron so that the attachment 41 of the shield cover 40 sticks to it, and some have excellent thermal conductivity in order to smoothly release the heat generated inside. It may also be formed with an aluminum plate or the like to serve as a heat sink.

In addition, by applying zinc coating or antioxidant coating to the surface of the main body 10, corrosion due to moisture can be prevented while preventing deformation due to heat of light irradiated from the sterilization module 11.

The bracket 20 is directly installed on the ceiling surface of the indoor space, and is provided to support the main body 10 while being attached to the ceiling surface.

The shielding cover 40 is attached to the lower part of the main body 10 to block ultraviolet rays generated from the sterilization module 11 from being directly irradiated.

That is, the shielding cover 40 completely closes the lower surface of the main body 10 and limits the radiation range of short-wavelength ultraviolet rays of about 100 to 290 nm generated from the sterilization module 11 to the side, so that ultraviolet rays harmful to the human body are directed toward the human body. Safety can be enhanced by blocking direct irradiation.

And inside the upper surface of the shield cover 40, a space is formed with a certain depth so that the fitting jaw 14 of the main body 10 is coupled as if inserted.

That is, the shielding cover 40 is formed to be coupled to the lower portion of the main body 10 in an interference fit or press fitting method.

Here, the shielding cover 40 is preferably formed of a material or material having a high UV blocking rate, such as opaque PC or PMAA, which can prevent discoloration or damage by UV rays while preventing UV rays in a short wavelength range.

That is, as shown in FIG. 6, since the head 33 of the bolt 32 is buried below the upper surface of the magnet 30, the contact and attachment area around the magnet 30 and the mount hole 22 is reduced to the guide hole. It is wider than (21), so it can maintain a natural and stable installation state.

In this process, as shown in FIG. 9 , since the catch 23 directly contacts the slider 35 or causes interference with each other to be in a locked state, that is, the catch 23 does not press in the slider 35. By holding it with the frictional force generated, it is possible to prevent the slider 35 from being easily separated from the mount hole 22 toward the guide hole 21 by an external force and moving or being separated. It can maintain the suspended state more firmly and stably.
