Description

{All-in-one air circulation apparatus for diffuser in integrated supply and exhaust}

The present invention relates to an air circulation device having the functions of supplying outdoor air to the indoors of a building and discharging and recirculating polluted air, wherein the device discharges indoor air to the outside in real time due to an increase in the concentration of carbon dioxide and various harmful substances and dust in the indoor air caused by the respiration of occupants, or supplies clean, outside air to the indoors, and ventilates indoor polluted air, filters the supply air recirculation, and then resupplies it indoors, thereby maintaining indoor air quality at all times as pleasant and hygienic, and quickly protecting the health of occupants in real time. The device relates to an integrated air circulation device using an integrated supply/ventilation drum and a diffuser.

Air circulators that are generally installed indoors are connected to the air circulator and diffuser via a supply/exhaust duct, and are a duct-connected air circulation method that brings in fresh air from the outside, discharges polluted substances inside to the outside, or circulates the internal air to filter out harmful substances such as dust and recirculates it to keep the indoor air pleasant.

These air circulation devices have ducts installed in the ceiling, so the interior is complex, construction is difficult, and construction costs a lot of time and money. After construction, if the ventilation device is used for a long time, fine dust and other contaminants accumulate inside the duct, and the contaminants are reintroduced into the room and harm the health of the occupants. In addition, the ducts installed like spider webs have a lot of resistance to air flow, which reduces ventilation efficiency. To prevent this, the blower motor capacity is increased or the rotation speed is increased, which generates a lot of noise and power consumption, and this is the cause of high maintenance costs.

Examples of methods to compensate for the shortcomings of these air circulators include diffusers and ventilation systems using them.

The above-mentioned diffuser and the ventilation system device using the same are a ventilation method using a drum-type diffuser, and are structured to significantly reduce the duct installation of existing air circulators. The diffuser and air circulator, which are installed independently, are connected to a duct and supply outside air, discharge indoor polluted air, or recirculate and supply indoor air and ventilate it.

The air recirculation supply and ventilation method of the above-mentioned diffuser and the ventilation system device using the same is an air circulation method in which the diffuser and the air circulator are independently installed separately on the ceiling finish surface and connected by a duct, and indoor ventilation is diffused into the ceiling through a perforated container box, and then introduced into the Linton ventilation port of the air circulator without a duct, filtered, and then re-supplied into the room by the diffuser through the duct;

The above problems are that the diffuser and the air circulator are connected by a duct, making it difficult to simplify the structure and reduce costs, the air supplied by the diffuser is supplied in only one direction, making it difficult to evenly supply and ventilate the room, and if the indoor area is wide or long, an additional diffuser must be installed, compromising the duct structure.

In addition, since the polluted air inside the room diffuses into the ceiling through the ventilation holes in the curtain box and then flows into the ventilation holes of the air circulator without a duct connection, not only will the polluted air stay in the ceiling and cause secondary pollution, but when the air circulator is in operation, indoor air will flow into the ceiling through the gaps in the ceiling finishing material or will flow back into the indoor area, contaminating the indoor area, reducing ventilation efficiency, and various pollutants inside the ceiling will flow into the air circulator, shortening the life of the filter and causing harmful substances to be reintroduced into the indoor area.

Accordingly, in order to solve these shortcomings, an integrated air circulation device using an integrated air supply/ventilation drum and diffuser was developed. Development is urgently needed.

Republic of Korea Patent Publication No. 10-2560357 (registered on July 24, 2023)

The present invention has been made to solve the above problems, and the purpose of the present invention is to provide an integrated air circulation device using an integrated air supply/ventilation drum and diffuser, which is installed in an indoor ceiling (panel) of a building, supplies fresh outside air into the indoor space without a duct through the indoor ceiling, and introduces polluted indoor air into an integrated air circulation device using an integrated air supply/ventilation drum and diffuser without passing through a duct, and supplies clean air that has passed through a filter into the indoor space again through the integrated air supply/ventilation drum and diffuser to circulate the air.

The present invention is a means for solving the above problems, and an air circulator is provided, in which an external tube for supplying external air and an exhaust tube for discharging indoor air are formed, and a heat exchange element and a filter in which the outdoor air and the exhaust air are mutually heat-exchanged at the inner central portion; a supply drum and a ventilation drum are attached to the air circulator by a partition plate (50) in which a supply port and a ventilation port are formed, and a lower portion of the supply drum is joined to an upper surface of the lower plate, and a diffuser is formed by joining the lower portion of the lower plate, so that an integrated air circulation device using an integrated supply/ventilation drum and a diffuser is formed; a ventilation drum is formed at the central portion of the above-mentioned supply drum, so that indoor air is introduced into the ventilation drum through the ventilation port of the diffuser joined to the lower portion of the ventilation drum, and is discharged to the outside through the exhaust tube via a filter and a heat exchange element through a ventilation drum connection port; The above-mentioned air supply drum provides an integrated air circulation device using an air supply/ventilation drum and a diffuser, which supplies outside air to the indoor space through an external pipe and an air supply opening, or recirculates and filters polluted air indoors and then supplies clean air.

As seen above, the present invention is very effective in preventing secondary pollution caused by duct installation due to the configuration of a ductless air circulation device, thereby always keeping indoor air clean.

In addition, since duct construction is omitted, air resistance caused by ducts can be reduced, ventilation efficiency is improved, installation location is free, construction costs are reduced, and the complicated ceiling interior due to ducts is simplified, making facility maintenance very convenient.

In addition, it is not restricted by the installation location even if the indoor size is the same in length, width, and height or if it is long or wide in one direction, and it has a very simple structure that does not require a separate diffuser to be installed or a duct between the diffuser and the air circulator, making it easy to construct on site, does not complicate the interior of the ceiling, and is a very economical air circulator with reduced installation costs.

Hereinafter, an integrated air circulation device using an integrated supply/ventilation drum and a diffuser according to a preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 to 10.

In the past, an air circulator and a duct were installed in the indoor ceiling, and a diffuser installed on the ceiling finish was connected to supply air or recirculate the air in the indoor area.

The present invention is a technology that has a very economical function in that it can reduce air resistance caused by the duct by eliminating the duct between the air circulator and the diffuser, improve ventilation efficiency, allow freedom in the installation location of the air circulator, reduce construction costs by not constructing the duct, make the interior of the ceiling not complicated due to the duct, and make it simple, easy to install, have low construction costs, and reduce costs for facility maintenance.

To this end, the present invention comprises an air circulation device (300) in which an air circulator (200), an air supply drum (100), and a diffuser (40) are integrally connected to each other;

The above air circulator (200) is responsible for the function of supplying fresh outside air to the room and exhausting polluted air to the outside. To this end, an outside pipe (210) for introducing outside air and an exhaust pipe (220) for exhausting ventilated indoor air are formed on the outer surface, and a heat exchange element (230) in which outside air and exhaust air exchange heat with each other in the inner central portion allows the hot indoor air that is exhausted and the cold outdoor air to exchange heat with each other, thereby simultaneously performing outside air and exhaust air, thereby saving energy and supplying clean, refreshing air to the room.

In addition, it includes various types of filters (240) for removing foreign substances in the air, and an air supply fan (250) and an exhaust fan (260) for supplying and exhausting air are built in, and a recirculation device is installed together.

As a technical feature of the present invention, a partition (50) having an air supply port (51) through which air is supplied and a ventilation port (52) for discharging or recirculating indoor air is attached to the inner surface of the air circulator (200), and an air supply drum (100) and a ventilation drum (30) are integrally connected to the partition (50).

The above-mentioned air supply drum (100) is formed with a ventilation drum (30) and an air supply space (60) excluding the external area of the ventilation drum, and the lower part of the air supply drum (100) and the lower part of the ventilation drum (30) are connected to the upper surface of the lower plate (45), and the lower surface of the lower plate (45) and the diffuser supply port surface (42) of the diffuser (40) are connected. The outside air and the air supply supplied to the indoor space are supplied to the indoor space through the air supply drum (100), and the polluted air from the indoor space is introduced into the ventilation drum (30) through the diffuser ventilation port (41) and discharged to the outside through the ventilation port (52) of the air circulator (200) connected to the ventilation drum connection port (31), or the function is to prevent the air supply and the air return from being mixed together during the recirculation process.

In addition, as another technical feature of the present invention,

A ventilation drum (30) is formed in the center of the above-mentioned air supply drum (100), so that indoor air ventilated through the diffuser (40) at the lower end is introduced into the ventilation drum (30), and passes through the heat exchange element (230) and filter (240) through the ventilation port (52) of the air circulator (200) connected to the ventilation drum connection port (31) to discharge or recirculate contaminated air to the outside through the exhaust pipe (220).

In addition, the external air and recirculated supply air introduced through the external organ (210) are introduced into the supply space (60) of the supply drum (100) through the supply port (51), and the integrated air supply/ventilation drum and diffuser are used to supply clean air to the indoor space through the diffuser supply port (42) of the diffuser (40) formed at the lower end of the supply drum (100).

In addition, as another embodiment of the present invention, as shown in FIGS. 1 and 2, the ventilation drum (30) is formed in a semicircular shape on the left and right sides rather than in a conventional rectangular box shape, so that external air is introduced into the air supply space (60) of the air supply drum (100) through the air supply hole (51) of the partition (50), and here, since the air may collide with the wall surface of the ventilation drum (30) formed horizontally apart from the air supply hole (51), which may increase air resistance or generate noise and vibration, this is to prevent the air from colliding with the wall surface of the ventilation drum (30).

The left and right sides of the ventilation drum (30) corresponding to the horizontal shape of the above-mentioned air supply port (51) are characterized by securing the air supply space (60) as wide as possible to prevent the air supplied from the air supply port (51) from colliding or interfering and to evenly distribute the air pressure, thereby ensuring even discharge and circulation of the air supplied to the room.

To explain this in a bailout way,
When the cross-sectional area of the above-mentioned air supply hole (51) overlaps with one side of the ventilation drum (30) in the horizontal direction, the one side of the ventilation drum (30) generates air resistance and noise from the outside air supplied from the air supply hole (51), so that the left and right sides of the ventilation drum (30) are evenly deleted to evenly distribute the air supply space (60), thereby minimizing the air resistance of the horizontal air supplied from the air supply hole (51) to one side of the ventilation drum (30), and thereby supplying air with an equal amount of air.
Of course, if the space of the above-mentioned air supply drum (100) is sufficient so that the outside air supplied from the air supply port (51) does not collide with the left and right sides of the ventilation drum (30), and the cross-sectional area of the above-mentioned air supply port (51) does not overlap one side of the ventilation drum (30) in the horizontal direction, the left and right sides of the ventilation drum (30) can be maintained at right angles.

In addition, as another embodiment of the present invention,

A diffuser ventilation hole (41) is formed in the center of the diffuser (40) through which indoor air is introduced, and a diffuser supply hole (42) through which outside air and recirculated air supplied to the supply space (60) of the air supply drum (100) are supplied to the indoor area is formed on the four sides of the diffuser (40), and a guide for controlling the amount of air supplied is built in to facilitate the control of the indoor air volume distribution environment.

The integrated air circulation device (300) according to the present invention comprises an air circulator (200), a supply air drum (100), a ventilation drum (30), and a diffuser (40) that are integrally connected to each other, and the supply air drum (100) and the ventilation drum (30) are integrally connected, and as shown in FIGS. 7 and 9, a diffuser (40) is installed based on a ceiling finish surface. In order to connect the supply air drum (100), the ventilation drum (30), and the diffuser (40), the ventilation drum (30) and the supply air drum (10) are connected to the upper surface of the lower plate (45) with the lower plate (45) as the center, and the lower surface of the lower plate (45) and the diffuser (40) are connected, so that indoor polluted air is discharged to the outside or recirculated through the ventilation drum (30) and the supply air drum (100) through the diffuser ventilation port (41) and the diffuser supply port (42);

The above-mentioned designed technology supplies clean outside air to the indoor space without an air supply duct or a ventilation duct, or recirculates and filters various polluted air such as dust in the indoor air and then resupplies it to the indoor space, thereby maintaining clear and clean air quality at all times and providing a healthy and comfortable indoor environment for the occupants.

As described above, although the present invention has been described by means of limited embodiments and drawings, the present invention is not limited thereto, and various modifications and changes are possible by a person skilled in the art to which the present invention pertains within the technical spirit of the present invention and the scope of equivalents of the patent claims to be described below.
