Description

Each room control air distribution panel that facilitates equal distribution of supplied air {AIR DISTRIBUTION PLATE USING INDIVISUAL ROOM CONTROL TECHNOLOGY FOR EQUAL AIR SUPPLY}

The present invention allows air to be supplied equally to the discharge pipe that supplies air to each room with respect to the incoming supply air, so that the indoor temperature inside the room and the supply of fresh air can be easily controlled. It relates to an air distribution panel for each room control that facilitates equal distribution of supplied air.

As is well known, air distributors have been used to improve indoor air quality, and a representative example can be found in Korea Public Utility Model Publication No. 20-2008-0000158.

As shown in Figure 1, this is an indoor ventilation system in which the total heat exchanger 10 is connected to the air distributor 20 through a duct, and the air distributor 20 is connected to the diffuser of each room through a small diameter duct. It consists of heating the outdoor air supplied from the outside by the indoor air heat discharged by the total heat exchanger 10, so that the temperature of the air supplied from the outside is appropriately raised and then supplied indoors, so that the indoor temperature is optimal. This was done to maintain the temperature and improve indoor air quality.

However, the conventional air distributor 20 supplies supply air consisting of cold air or warm air from the total heat exchanger 10 to the air distributor so that it can have a predetermined discharge pressure, as shown in FIG. 2. A phenomenon occurs in which the supply air, which maintains straight flow, is supplied biased mainly through the discharge pipe of the low-resistance zone (Z1), resulting in the inflow of the supply air toward the zones (Z2) with slightly higher resistance other than the zone (Z1). Because this is relatively poor, a problem arises in that the user cannot easily adjust the indoor temperature of the air in the room connected to the discharge pipe.

Domestic Public Practice No. 20-2010-2036 (Publication date: 2010.02.26.) Domestic Public Use No. 20-2008-0000158 (Publication date: 2008.02.12.)

In order to solve the above-described conventional problems, the present invention makes it easy to achieve the indoor temperature desired by the user without frequent manipulation by inducing the supply air supplied from the total heat exchanger to the air distributor to be distributed equally to each room. The purpose is to provide an air distributor that can be realized easily.

In order to solve the above-described technical problem, each room control air distribution plate, which facilitates equal distribution of supplied air according to the present invention, is connected to the heating device 10 and a pipe to supply at least one of cold air or warm air. In the air distributor supplying air to a room differently partitioned by a plurality of discharge pipes 310, the air distributor includes an air distribution plate 100 for equally distributing the supplied air to each discharge pipe 310. However, the air distribution plate 100 is made in the shape of a plate and is installed to be replaceable with the air distributor, and is characterized by a plurality of air distribution holes 110 perforated on the outer surface facing each discharge pipe 310. Do it as

In addition, the air distribution hole 110 includes a first air distribution hole 111 and a second air distribution hole 113 having different diameter sizes D1 and D2, and is located directly below the discharge pipe 310. It is preferable that the diameter D1 of the first air distribution hole 111 is smaller than the diameter D2 of the second air distribution hole 113.

In addition, the air distribution plate 100 further includes a plurality of air guide plates 120, and the air guide plates 120 are formed to protrude in the direction of the discharge pipe 310 to be connected to the outer surface of the air distribution plate 100. It is desirable to guide the supply air after passing through the first air distribution hole 111 or the second air distribution hole 113 to be equally supplied to each discharge pipe 310.

In addition, at least one of the air guide plates 120 is preferably formed to protrude in a diagonal shape so that the supply air distributed through the second air distribution hole 113 can be guided in the direction of the discharge pipe 310. do.

In addition, the plurality of air guide plates 120 create a space where the supplied air after passing through the first air distribution hole 111 or the second air distribution hole 113 can be mixed with each other inside the air distributor. In order to secure this, an air distribution plate for each room control that facilitates equal distribution of supplied air is provided, which is characterized by being protruded to have a predetermined gap with the discharge pipe 310.

According to the present invention, unlike the prior art, the supply air supplied en masse to the inside of the space formed by combining the upper body and the lower body is distributed evenly and guided to be supplied in the direction of a plurality of discharge pipes, without frequent manipulation. This also provides the convenience of being able to easily control the indoor temperature inside the room desired by the user.

On the other hand, when it is mentioned that a component is “directly connected” or “directly connected” to another component, it should be understood that there are no other components in between.

In addition, when describing the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof is abbreviated or omitted.

Hereinafter, with reference to the attached drawings, the room control air distribution plate (hereinafter simply referred to as 'air distribution plate'), which facilitates equal distribution of supplied air according to the present invention, will be described in detail.

First, as shown in FIGS. 3 to 5, the air distribution plate 100 according to the present invention largely includes an air distribution hole 110 and an air guide plate 120, and the air distribution plate 100 A lower body 300 formed in the shape of a plate made of a material such as synthetic resin and formed with a plurality of discharge pipes 310, and a heating device 10 that exchanges heat between indoor and outdoor air and supply air containing cold air and warm air, and It is installed so that it can be replaced between air distributors consisting of an upper body (200) joined to a pipe (PIPE).

For this purpose, a coupling hole 130 for fitting with the coupling protrusion 250 formed on the upper body 200 or the lower body 300 is perforated on the outer surface of the air distribution plate 100, and each discharge pipe 310 ) A plurality of air distribution holes 110 are perforated equal to the number.

For example, the air distribution hole 110 is designed so that the supply air flowing into the air distributor can be easily supplied through each discharge pipe 310 by being guided by the air guide plate 120, which will be described later. It includes a first air distribution hole (111) and a second air distribution hole (113).

At this time, the first and second air distribution holes 111 and 113 are perforated as large as possible, excluding the part that faces the upper body 200, compared to the entire area of the air distribution plate 100, so that the supply flowing in from the electric heating device is formed. It is desirable to ensure that minimal resistance is applied to the air flow.

Here, as shown, the first air distribution hole 111 refers to a distribution hole perforated on the outer surface of the air distribution plate 100 located directly above the discharge pipe 310, and the second air distribution hole 113 ) means distribution holes other than the first air distribution hole 111, that is, distribution holes that are not located directly above the discharge pipe 310.

Therefore, the number of the first and second air distribution holes 111 and 113 may vary depending on the number or formation position of the discharge pipes 310 formed in the lower body 300, and is not limited in the present invention. In order to clearly understand the gist of the invention, note that the explanation is given as an example in which the discharge pipes 310 form two rows, with a total of six discharge pipes 310, three for each row.

Meanwhile, in the present invention, the perforation width D1 of the first air distribution hole 111 is preferably smaller than the perforation width D2 of the second air distribution hole 113, because the upper The flow of supply air passing through the air distribution hole 110 through the body 200 causes most of the air to flow through the discharge pipe 310 located at the closest distance, and only a relatively small amount of air flows from the discharge pipe at the edge. will be supplied.

When the opening areas of the first and second air distribution holes 113 are the same, the air resistance of the air distribution hole that is closer is lower than that of the air distribution hole that is farther away, so the air supplied through the discharge pipe 310 is relatively small. A problem may arise in which the inflow amount is biased toward the first air distribution hole (111) rather than the second air distribution hole (113).

Therefore, in order to solve the above-mentioned problem, the perforation width of the first air distribution hole 111 is made smaller than that of the second air distribution hole 113 to discharge the supply air supplied through the plurality of air distribution holes 110. This is to artificially keep the resistance (back pressure) at the same level.

In addition, the air guide plate 120 guides the flow of supply air supplied through the above-mentioned air distribution hole 110 to be evenly distributed inside the air distributor, thereby allowing the supply air to be supplied through the plurality of discharge pipes 310. It is designed to ensure that air is supplied evenly.

For this purpose, as shown, the air guide plate 120 is formed to protrude downward from the outer surface of the air distribution plate 100 facing the discharge pipe 310 to have a length in the horizontal and vertical directions to facilitate the flow of supply air. induce.

At this time, at least one of the plurality of air induction plates 120, in particular, a pair of air induction plates protruding on both sides of the first air distribution hole 111 located between the pair of second air distribution holes 113. It is preferable that (120) protrudes in the shape of diagonal lines that are symmetrical to each other so that the supply air distributed through the second air distribution hole (113) can be guided in the direction of the discharge pipe (310).

Due to the provision of such a plurality of air guide plates 120, the supply air flows equally into both the zone (Z1) where the resistance of the supply air flowing into the space is low and the zone (Z2) where the resistance is high, so that the supply air flows into each discharge pipe. It is possible to supply air without difference even at (310) (see Figure 6).

At this time, high and low resistance means the difference between the case where the distance that the supplied air must pass through is short (the back pressure is small, or the resistance is small) and the case when it is long (the back pressure is large or the resistance is large), so that the air is evenly distributed. When supplied, a large flow of air occurs where there is low resistance (back pressure), and a relatively small air flow occurs where there is high resistance (back pressure).

Therefore, if the back pressure is equalized, the amount of air flowing through each discharge pipe 310 can be equalized, so equalization of the back pressure, or resistance, is necessary.

Due to the provision of such a plurality of air guide plates 120, the supply air flows equally into both the zone (Z1) where the resistance of the supply air flowing into the space is low and the zone (Z2) where the resistance is high, so that the supply air flows into each discharge pipe. It is possible to supply air without any difference in (310) (see Figure 7).

In addition, as shown, the plurality of air guide plates 120 allow the supplied air after passing through the first air distribution hole 111 or the second air distribution hole 113 to be easily mixed with each other inside the air distributor. It is formed to protrude to have a predetermined gap.

The need for the supply air to be easily mixed with each other inside the air distributor is that the supply air supplied through each air distribution hole is not always open as needed because each discharge pipe 310 matching each air distribution hole is not always open. Since the air supplied to the closed discharge pipe 310 cannot flow because the discharge pipe is blocked, the air supplied to the neighboring discharge pipe 310 is easily mixed with each other and is guided so that it can pass easily. The plate 120 is made to have a predetermined distance from the discharge pipe 310.

Meanwhile, as shown in FIGS. 8 and 9, the air distributor structure of the present invention has a configuration that is different from that of the prior art, and this air distributor will be described in detail below.

First, the air distributor in the present invention includes an upper body 200, a lower body 300, and an opening and closing member 400 equipped with the above-described air distribution plate 100, and electrical The advantage of smoothly controlling the opening and closing of each discharge pipe 310 is achieved through control.

To elaborate, as shown in FIGS. 10 to 12, the upper body 200 is coupled to the lower body 300, which will be described later, by fastening means such as bolts or screws to have the shape of a hollow housing to form a heat electric device. It is configured to allow the supply air supplied from (10) to flow in smoothly without leaving the outside, and includes at least one of the connection socket 210 or the wire cover box 220.

For example, the upper body 200 is molded using a synthetic resin material, and as shown, the inlet side connected to the pipe with the heating device 10 and the outlet side where the lower body 300 are joined are molded in an open shape, so that the inlet side It has a structure that allows the supply air flowing in from the outlet side to move by the discharge pressure.

A groove is formed on the inlet side of the opened upper body 200 into which the air distribution plate 100, which will be described later, can be detachably inserted and coupled, and a plurality of coupling protrusions 250 are protruding and formed on the bottom surface of the groove for coupling. It has a structure that can be fitted with the ball 130.

An insertion hole 230 may be formed on the outer surface of the upper body 200 to slide the filter plate 240 into the inner surface, and the insertion hole 230 allows the air distribution plate 100 to be inserted into the upper body 200. ), since interference with the filter plate 240 may occur when provided in the air distributor, if necessary, it is formed on the outer surface of the connection socket 210 or the lower body 300 and the filter plate 240 is combined into a box shape. Allow it to be inserted into the inner space.

Here, the insertion hole 230 into which the filter plate 240 is inserted is opened and closed by the hook pin 231 so that the inserted filter plate 240 can be fixed, and the fixation causes the generated air to flow in. It is possible to prevent flow due to vibration and at the same time prevent the supply air from being lost to the outside.

In addition, as shown, the connection socket 210 is formed in the shape of a cap with openings on both sides, and the flange portion can be detachably coupled to the open inlet side of the upper body 200 by a fastening means. It is connected to the heating device 10 and a pipe (PIPE) to allow the inflow of supply air.

In addition, the wire cover box 220 is detachably coupled to the outer surface of the upper body 200, but is provided with a PCB circuit board (not shown) inside, and rotates through the opened lower part to form the opening and closing member 400, which will be described later. Ensure that the motor 410 is electrically connected to the corresponding PCB circuit board.

At this time, it is preferable that the PCB circuit board is electrically connected to the control unit 20 that controls the electric heating device 10 to enable individual control of the plurality of rotation motors 410, and through such individual control, multiple rooms ( Control of the supply air supplied to the ROOM is made possible electrically.

And, as shown in FIGS. 13 and 14, the lower body 300 is detachably coupled with the above-described upper body 200 by means of a fastening means, and is connected to the outside of the supply air supplied from the electric heating device 10. It is designed to collect and supply to each room without leakage.

For this purpose, as shown, the lower body 300 is perforated on the outer surface so that a plurality of discharge pipes 310 are arranged in a checkerboard arrangement, and a rotation control protrusion 421 and an interview surface are provided close to each discharge pipe 310. The first stopper 320 is protruding and connected to the outer surface of the lower body 300.

At this time, each discharge pipe 310 is composed of two powders that can be separated and combined by a fastening means, and after separation, an opening and closing plate 420 rotatably coupled to the inside by the drive shaft of the rotation motor 410 is replaced. It is desirable to make it possible to install it.

In addition, the outer surface of the discharge pipe 310, which is made of two powders and has an inner diameter of a predetermined diameter, is provided with an opening and closing plate 420 rotating toward its center, and a material that can control the rotation of the opening and closing plate 420. 2 Stoppers 330 may be additionally formed.

On the side of the lower body 300, there are a plurality of fastening means equal to the number of the discharge pipes 310 so that the opening and closing member 400, which can open and close each discharge pipe 310, can be controlled by one PCB circuit board. It is installed through to have a structure that allows the discharge pipe 310 to be opened and closed individually.

In addition, as shown in FIGS. 15 to 17, the opening and closing member 400 is provided on the lower body 300 described above to individually open and close each discharge pipe 310 through control of the PCB circuit board. It is configured to implement supply and blocking of supply air by opening and closing and includes a rotation motor 410 and an opening and closing plate 420.

A plurality of rotation motors 410 are provided on the side of the lower body 300 so that the body can be blocked from the outside by a cover to minimize external influences (for example, to prevent durability degradation due to the inflow of moisture or foreign substances). And the drive shaft has a structure that penetrates the lower body 300.

Here, the rotation motor 410 uses a two-way motor that can rotate in both the forward (for example, clockwise) and reverse directions, and rotates the opening/closing plate 420 so that it is vertical or horizontal depending on the direction of rotation, so that the discharge pipe ( 310) must have a structure that allows opening and closing.

As shown, the opening and closing plate 420 is molded to have the shape of a disk with a predetermined diameter using synthetic resin materials, etc., and if necessary, a plurality of ribs are formed to maintain the durability of the opening and closing plate 420. so that its original form can be maintained.

One side of the opening/closing plate 420 is arranged so that its outer diameter faces the inner diameter of the discharge pipe 310 so that it can be rotatably coupled to the drive shaft of the rotation motor 410 penetrating the lower body 300, so that it can be rotatably coupled to the inner diameter of the discharge pipe 310 by its rotation. The discharge pipe 310 must have a structure that can be opened and closed.

At this time, on one side of the opening and closing plate 420, there is a rotation control protrusion 421 that can control the rotation direction or angle of the opening and closing plate 420 by interacting with the first stopper 320 protruding from the lower body 300 when rotating. ) is preferably formed.

In addition, the opening and closing plate 420 rotating within the discharge pipe 310 allows its outer surface to come into contact with the second stopper 330 according to its rotation direction, and preferably includes the first stopper 320 and the rotation control protrusion. When (421) is rotated so that it can face each other, the discharge pipe (310) is kept in an open state, and when the second stopper (330) and the opening and closing plate (420) face each other, the discharge pipe (310) This is closed to block supply air from being supplied to the room.

That is, the opening and closing of the discharge pipe 310 in the present invention is such that either the rotation control protrusion 421 and the first stopper 320 or the opening and closing plate 420 and the second stopper 330 can face each other. Rotation of the opening and closing plate 420 is implemented to enable opening and closing of the discharge pipe 310.

Although it is described as a structure that can be opened and closed, this is only one embodiment, and if necessary, the opening and closing plate 420 is rotated step by step within the corresponding rotation radius of 90 degrees to increase the open area of the discharge pipe 310. Please note that it is also possible to adjust the inflow amount of supply air.

Meanwhile, the air distribution plate 100 in the present invention can be used in different shapes, as shown in FIG. 18, and in particular, the multiple air guide plates 120 have a shape that protrudes more in the direction of the supply air. As a result, it is possible to implement the effect of the air distribution plate 100 described above by minimizing interference with the inflow of air.

As described above, the air distribution plate 100 according to the present invention is different from the conventional one in that the supply air supplied in batches to the inside of the space formed by the combination of the upper body 200 and the lower body 300 is evenly distributed. By guiding the supply to the direction of the plurality of discharge pipes 310, the effect of providing the convenience of easily controlling the indoor temperature inside the user's desired room and providing fresh air without frequent manipulation is achieved.
