Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air sterilization apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air sterilizing apparatus having an increased residence time, and more particularly, to an air sterilizing apparatus which improves the sterilizing power of bacteria and microorganisms in the air by increasing the contact time between air and air, .

Generally, ultraviolet sterilization apparatus refers to a device which is designed to sterilize bacteria adhering to a toxic substance by irradiating ultraviolet rays to a toxin poison. Until recently, the mainstream of such ultraviolet sterilization apparatuses is a toxic substance such as a sanitary apparatus or a medical apparatus, And since the sterilizing effect by ultraviolet rays has become more widely known, recently, there have also appeared those which are designed to sterilize the indoor air by using ultraviolet rays in the ultraviolet sterilizing apparatus.

The ultraviolet sterilization apparatus for indoor air disinfection is provided for the purpose of preventing human body infection by bacteria in the air and is used in various places such as an operating room and a clean room as well as a general home. A stabilizer connected to the ultraviolet lamp, and a blower connected to the chamber so as to allow the outside room air to flow into the chamber and to be discharged to the outside of the chamber.

The inflow part, the ultraviolet lamp and the stabilizer are accommodated in the chamber, and the inflow part and the ballast are generally individually fixed at different positions in the chamber by separate brackets.

In the ultraviolet sterilization apparatus configured as described above, the indoor air is sucked into the chamber through the suction port of the chamber during the operation of the discharge unit, sterilized while passing around the UV lamp, and then discharged to the outside of the chamber through the discharge port of the chamber.

However, in the conventional ultraviolet sterilizing apparatus, the air is substantially horizontally moved into the chamber in which the ultraviolet lamp is installed, and the air retention time in the chamber is very short, so that a sufficient sterilization effect can not be expected. Particularly, the air which is horizontally moved in proximity to the ultraviolet lamp is sterilized to a certain degree. However, since the ultraviolet irradiation dose is not enough for the horizontally moving air close to the inner wall of the chamber, the biological bacteria are not completely sterilized And the total sterilization efficiency is lowered.

In order to increase the residence time of the air in the chamber, there is an air duct for allowing the air to flow spirally through the chamber so as to circulate the air along the circumference of the ultraviolet lamp. However, the chamber having such a helical air duct It is very difficult to manufacture, and it takes a lot of manufacturing cost and time, and there is a problem that a load is generated in the air flow and the blower must be controlled separately. Especially, the helical air duct has many problems such that the flow of the air is kept fast and it does not have a great influence on the residence time of the air.

Patent Registration No. 10-1386404 (Apr. 4, 2014)

An object of the present invention is to provide an air sterilization apparatus which can prolong an air retention time in the air sterilizing apparatus and can expect an effective sterilization effect even by using only one ultraviolet lamp.

A plurality of diaphragms provided in parallel to each other in a staggered manner in a zigzag manner in the housing and having a suction port and one side of the housing communicating with each other; An air passage formed in a zigzag form in the housing by a plurality of diaphragms so that the other side end communicates with the discharge port of the housing; and an ultraviolet lamp which is installed in parallel with the diaphragm in the air passage so as to be positioned on the suction port side of the housing So,

The contaminated air introduced into the housing is repeatedly moved from the upper side to the lower side along the air passage again from the lower side to the upper side many times or repeatedly moved from right to left several times from the left side to the right side, To be sterilized repeatedly a number of times.

The present invention maximizes the residence time of the air by moving the air through the air passages stacked in multiple layers, and ultraviolet rays irradiated from one ultraviolet lamp penetrate a plurality of diaphragms made of transparent polyethylene to sterilize the air in the air passage Therefore, it is possible to provide an excellent air sterilization effect.

1 is an illustration showing a configuration according to the present invention;
2 is a view showing an air flow and an ultraviolet sterilization process according to the present invention;

FIG. 2 is a view illustrating an air flow and an ultraviolet sterilization process according to an embodiment of the present invention. FIG. 2 is a schematic view illustrating a blower 10, A housing 20 having a suction port 21 and a discharge port 22; a plurality of diaphragms 30 arranged in parallel in a zigzag form in the housing 20 and made of transparent polyethylene; An air passage 40 formed in a zigzag form in the housing by a plurality of diaphragms 30 so that one end is communicated with the suction port 21 of the housing 20 and the other end is communicated with the discharge port 22 of the housing, And an ultraviolet lamp 50 installed parallel to the partition plate 30 in the air passage 40 so as to be positioned on the suction port 21 side of the partition plate 30,

The contaminated air introduced into the housing 20 is repeatedly moved repeatedly from the upper side to the lower side along the air passage 40 again or repeatedly from the left to the right again a number of times from the right to the left, Is repeatedly sterilized by the ultraviolet ray transmitted through the ultraviolet ray irradiation unit 30, and then discharged to the room through the discharge port.

The blower 10 is installed in the housing 20 and operates to provide a suction force to the suction port 21. The contaminated air flowing into the suction port 21 is moved through the air path 40 to be irradiated with ultraviolet rays, 22). The blower 10 may be installed in the housing so as to be located at the inlet or outlet of the housing and may be installed at the end of the air passage 40 so as to be positioned at the outlet.

The housing 20 has a suction port 21 communicating with one side of the air passage 40 at one side and a discharge port 22 communicating with the other side of the air passage 40 at the other side. 40 are formed.

In addition, the suction port 21 is further provided with a filter 23 for removing particulate matter of polluted air. The filter 23 is a well-known filter, and a detailed description thereof will be omitted.

In addition, the housing 20 is further provided with a reflection plate 24 made of a thin aluminum foil on its inner surface, so that the space inside the housing 20 is entirely formed as an ultraviolet sterilizing area.

The diaphragm 30 is installed in the housing 20 so as to maintain a predetermined space therebetween so that the air introduced into the housing 20 through the air inlet 21 is zigzagged in the vertical direction or in the left- 40 are formed.

The diaphragm 30 installed in this way forms an air passage 40 having a multi-layered space vertically or horizontally in the housing 20, so that the residence time of the air is kept long.

The diaphragm 30 is made of transparent polyethylene so that ultraviolet rays irradiated by one ultraviolet lamp installed to be positioned on the suction port side can reach and reach the discharge port side.

The material of the diaphragm is limited so that ultraviolet rays are irradiated to all air channels by one ultraviolet lamp even if air passages are formed by stacking a plurality of air channels. When a diaphragm made of a material is provided, ultraviolet rays are not transmitted, and the sterilizing effect as in the present invention can not be maintained.

In addition, since the diaphragm of the present invention is made of a polyethylene material, the diaphragm of the present invention is not only capable of being formed into a large area but also has a characteristic that no cracking phenomenon occurs even when the diaphragm is formed into a large area.

In other words, since the diaphragm made of the polyethylene material of the present invention can be formed into a large area that can not be formed by conventional quartz materials, the air retention time can be maximized, ultraviolet ray transmission can be performed, And has a characteristic capable of obtaining an ultraviolet sterilization effect.

The air passage 40 is a purification space for purifying contaminated air, and is formed in the housing 20 so as to have a zigzag shape (repeated shape) by a plurality of diaphragms. The air passage 40 thus formed has a shape in which a plurality of air flow paths are stacked.

That is, as shown in FIG. 1, when four diaphragms are provided in the housing, the first and third diaphragms 31 and 33 are arranged such that the right ends 31a and 33a are separated from the right inner surface 20a of the housing by a predetermined distance The left ends 31b and 33b are integrally connected to the left inner surface 20b of the housing and the left and right ends 32b and 34b of the second and third diaphragms 32 and 34 are connected to the left inner surface 20b of the housing The right ends 32a and 34a are integrally connected to the right inner surface 20a of the housing so that the first, second, third, and fourth diaphragms 31, 32, 33, and 34 are parallel to each other And a housing

A space between the upper inner surface 20c of the housing located on the intake port 21 side and the first partition plate 31 is defined by a space between the first air passage 41 and the first and second partition plates 31 and 32, A space between the second and third diaphragms 42 and 33 is formed between the third air passage 43 and the third and fourth diaphragms 33 and 34 in the space between the fourth air passage 44 and the fourth diaphragm 34 and the lower inner surface 20d corresponds to the fifth air passage 45,

The first, second, third, fourth, and fifth air passages 41, 42, 43, 44, and 45 are vertically stacked in the housing 20 and are formed as one air passage 40.

The ultraviolet lamp 50 is installed on one side of the air passage connected to the suction port 21 by being protected by a quartz tube or a transparent polyethylene tube. At this time, the ultraviolet lamp (50) is installed parallel to the plurality of diaphragms (30).
