First, referring to FIGS. 1A to 1C, a four-way ceiling heating and cooling unit 100 having a hopper and a rotary discharge port according to a first embodiment of the present invention will be described in detail as follows.

The air inlet 110 serves as an inlet through which air in the room IN is sucked by the suction force caused by the rotation of the fan 120 to be described later. Here, the air inlet 110 may include a filter 111 for filtering the air. That is, the filter 111 removes fines or odors from the air in the room IN so that only the purified air flows into the fan 120 through the air inlet 110. On the other hand, the air intake port 110 is formed adjacent to the side of the air discharge port 150, is formed below the ceiling (C), and sucks air from the side of the air discharge port 150. That is, the inlet 112 of the air inlet 110, through which the air in the room IN is sucked, is formed parallel to the direction in which the ceiling C is formed to substantially suck air from the side of the air outlet 150. Therefore, the air passage from the air intake port 110 to the fan 120 is formed adjacent to the side of the fan 120 and the drive unit 130.

The pan 120 serves to flow from the room IN through the air inlet 110 by rotation. On the other hand, the fan 120 is composed of a rotation shaft 121 and a plurality of wings 122 that rotate substantially about the rotation shaft 121. Here, the rotating shaft 121 is formed in a direction perpendicular to the floor of the room (IN), the wing 122 rotates about the rotating shaft 121 to the air introduced from the air inlet 110 of the fan 120 The rotating shaft 121 is discharged outward, that is, in the lateral direction of the fan 120 as shown in FIG. 1A.

The driver 130 is formed to be coupled to the lower side of the fan 120, and drives the fan 120 to rotate. Here, the driving unit 130 may be formed of a motor coupled to the rotation shaft 121 of the fan 120. On the other hand, the lower side of the fan 120 means one side of the fan 120 facing the floor of the indoor (IN).

The air conditioning coil 140 cools or heats the air flowing through the air by the rotation of the fan 120. Here, the air-conditioning coil 140 may include at least one or more of a steam coil, a cold and hot water coil, and a linear coil using an electric heat source.

The air discharge port 150 is formed in the lower center area of the driving unit 130 and is provided by the rotation of the fan 120 to discharge air, which is selectively cooled by the heating / cooling coil 140, to the indoor IN. On the other hand, the lower side of the drive unit 130 means one side of the drive unit 120 facing the floor of the room (IN).

An accelerating hopper 160 is formed between the air-conditioning coil 140 and the air outlet 150 to guide the air cooled air to the air outlet 150. Here, the speed increase hopper 160 is formed in a shape that narrows the passage surface of the air toward the air discharge port 150 to accelerate the air discharged by the air discharge port 150. That is, when the air passing through the air-conditioning coil 140 is discharged to the air discharge port 150, as is well known by the Bernoulli theorem, the speed increase hopper 160 is formed in a shape that the air flow surface is narrowed Is accelerated to increase. Specifically, as shown in Figure 1a, the speed increase hopper 160 is formed so that the passage surface of the air narrowed in the tapered shape, the flow rate is accelerated to increase. Thus, as shown in Figure 1c, the discharge rate of the air can be increased to reach the heating and cooling air to the floor (IN), it is possible to uniformly and uniformly heat the entire interior space of the indoor (IN).

On the other hand, the end portion 161 of the tapered speed increase hopper 160 adjacent to the air discharge port 150 may be formed to be extended by a predetermined length in the inward direction. Accordingly, the flow rate of the air discharged to the air discharge port 150 may be further accelerated to further increase the flow rate.

In addition, the air discharge port 150 discharges air at a predetermined angle inclined toward the bottom of the room IN in the outward direction with respect to the rotation shaft 121 of the fan 120 by the guide 152. That is, the air discharge port 150 discharges the air cooled and cooled at a discharge angle inclined with respect to the floor of the indoor IN, thereby uniformly and uniformly discharging the air cooled and heated in the indoor IN, Can be air-conditioned regularly.

On the other hand, reference numeral 171 is a fixing member for fixing the indoor unit to the ceiling area, reference numeral 172 is to seal between the speed increase hopper 160 and the air discharge port 150, or between the air discharge port 150 and the air intake port 110. It is a sealing member.

In addition, one side of the air discharge port rotating unit 180 is formed in combination with the air discharge port 150 and the other side of the air discharge port rotating unit 180 is in surface contact with the air passing through the speed increase hopper 160, the air corresponding to the speed of the air The discharge port 150 is rotated at a constant speed. Here, the air discharge port rotating unit 180 is a rotary unit 181 that rotates in surface contact with the air passing through the speed increase hopper 160, for example, a plurality of blades (blade), and the central axis of rotation of the air discharge port 150 ( The reduction gear 182 is formed in conjunction with the 151, and rotates the rotation unit 181 at a constant rate to rotate the air discharge port 150 at a constant speed around a rotation axis perpendicular to the floor of the room IN. ) For example, the reduction gear 182 may be coupled to the first gear 182-1 coupled to the rotation center axis 181-1 of the rotation unit 181, and to the rotation center axis 151 of the air discharge port 150. A second gear 182-2 meshing with the first gear 182-1, and the first and second gears 182-1, 182-2 of the reduction gear 182 are formed of the rotary unit 181. The rotation is decelerated at a ratio of 100: 1 to rotate the air outlet 150 at a constant speed. As described above, when the air discharge port 150 corresponds to the air speed by the air discharge port rotating unit 180, that is, the speed of the air passing through the speed increase hopper 160 is relatively slow, the rotating unit 181 rotates slowly. When the air outlet 150 rotates slowly, and the speed of the air passing through the speed increase hopper 160 is relatively fast, the rotary unit 181 rotates quickly, and the air outlet 150 rotates rapidly, thereby reducing the overall interior IN. The air may be uniformly and uniformly cooled regardless of the distance from the air outlet 150. Meanwhile, the air discharge port rotating unit 180 includes a rotation drive unit (not shown) including a motor and a drive shaft (not shown) for providing the rotation driving force of the rotation drive unit to the rotation center axis 151 of the air discharge port 150. It may be made of). That is, although the air discharge port 150 may be rotated by the discharged air, the air discharge port 150 may be forcibly rotated by the rotation drive unit including the motor. In addition, the air outlet 150 may rotate at a rotational speed of 0.5 to 1.0 times per minute.

Next, referring to Figures 2a to 2c, it will be described in detail the ceiling four-way air-conditioning indoor unit 200 having a speed increase hopper and a rotary discharge port according to a second embodiment of the present invention.

The air inlet 210 serves as an inlet through which air in the room IN is sucked by the suction force caused by the rotation of the fan 220 to be described later. Here, the air intake 210 may include a filter (not shown) for filtering the air. That is, the filter removes fines or odors from the air in the room IN so that only the purified air flows into the fan 220 through the air inlet 210.

Meanwhile, the air inlet 210 is formed to be spaced apart from the air outlet 250 by a predetermined distance, and air is sucked into the fan 220 through the duct 270 formed between the air inlet 210 and the fan 220. . Here, the duct 270 is formed in the inner space of the ceiling (C) is formed so as not to be exposed to the room (IN), and formed in a predetermined length so that the entire large space of the room (IN) can be cooled and heated to a uniform and constant temperature And serves as an inflow passage of air from the air intake port 210 to the fan 220. That is, the duct 270 extends a predetermined length so that the fan 220 and the air intake port 210 communicate with each other so as to smoothly suck the air in the room IN far from the fan 220 or the air discharge port 250. do.

In addition, the outdoor air is formed to communicate with the outdoor (OUT), the indoor (IN) and the duct 270, respectively, while the indoor air is exchanged with the air from the outdoor (OUT), the indoor air is outdoors (OUT) The outdoor air may further include a heat exchanger 280 for introducing into the duct 270. That is, the heat exchanger 280 discharges the air of the indoor IN to the outside and introduces the air of the outside to the fan 220 through the duct 270 to ventilate the indoor air. At the same time, the indoor air and the outdoor air may be exchanged to prevent overload of the driving unit 230 or the cooling / heating coil 240.

The fan 220 serves to flow from the room IN through the air inlet 210 by rotation. Meanwhile, the fan 220 includes a rotation shaft 221 and a plurality of blades 222 that rotate substantially about the rotation shaft 221. Here, the rotating shaft 221 is formed in a direction perpendicular to the floor of the room (IN), the blade 222 is rotated about the rotating shaft 221 to the air introduced from the air inlet 210 of the fan 220 The rotary shaft 221 is discharged in an outer direction, that is, in a side direction of the fan 220 as shown in FIG. 1A.

The driver 230 is formed to be coupled to the lower side of the fan 220, and drives the fan 220 to rotate. Here, the driving unit 230 may be formed of a motor coupled to the rotation shaft 221 of the fan 220. On the other hand, the lower side of the fan 220 means one side of the fan 220 facing the floor of the indoor (IN).

The air-conditioning coil 240 cools or heats the air flowing through the air by the rotation of the fan 220. Here, the air-conditioning coil 240 may include at least one or more of a steam coil, a cold and hot water coil, and a linear coil using an electric heat source.

The air discharge port 250 is formed in the lower center area of the driving unit 230, and is provided by the rotation of the fan 220 to discharge air, which is selectively cooled and heated by the cooling / heating coil 240, to the indoor IN. On the other hand, the lower side of the driving unit 230 means one side of the driving unit 220 facing the floor of the indoor (IN).

An increase hopper 260 is formed between the air conditioning coil 240 and the air outlet 250 to guide the air cooled and air cooled to the air outlet 250. Here, the speed increase hopper 260 is formed in a shape that narrows the passage surface of the air in the direction of the air discharge port 250 to accelerate the air discharged by the air discharge port 250. That is, when the air passing through the air-conditioning coil 240 is discharged to the air discharge port 250, the speed increase hopper 260 formed by the Bernoulli theorem, the air flow rate is narrowed by the Bernoulli theorem, as is well known. Is accelerated to increase. Specifically, as shown in Figure 1a, the speed increase hopper 260 is formed so that the passage surface of the air narrowed in a tapered shape, the flow rate is accelerated to increase. Thus, as shown in Figure 2c, the discharge speed of the air can be increased to reach the heating and cooling air to the floor (IN), it is possible to uniformly and uniformly heat the entire interior space of the indoor (IN).

On the other hand, the end portion 261 of the tapered hopper 260 adjacent to the air discharge port 250 may be formed to be extended by a predetermined length in the inward direction. Accordingly, the flow rate of the air discharged to the air discharge port 250 may be further accelerated to further increase the flow rate.

In addition, the air discharge port 250 discharges air at a predetermined angle inclined toward the bottom of the room IN in the outward direction with respect to the rotation shaft 221 of the fan 220 by the guide 252. That is, the air discharge port 250 discharges the air cooled and cooled at a discharge angle inclined with respect to the floor of the indoor IN, thereby uniformly and uniformly discharging the air cooled and heated in the indoor IN, Can be air-conditioned regularly.

On the other hand, reference numeral 291 is a sealing member for sealing between the speed increase hopper 260 and the air discharge port 250, reference numeral 292 is a fixing member for fixing the indoor unit to the ceiling area.

In addition, one side of the air discharge port rotating unit 300 is formed in combination with the air discharge port 250 and the other side of the air discharge port rotating unit 300 is in surface contact with the air passing through the speed increase hopper 260, the air corresponding to the speed of the air The discharge port 250 is rotated at a constant speed. Here, the air discharge port rotating unit 300 is a rotary unit 301 that rotates in surface contact with the air passing through the speed increase hopper 260, for example, a plurality of blades, and the rotational central axis 251 of the air discharge port 250 and It is formed of a reduction gear 302 which is formed by coupling, to reduce the rotation of the rotary unit 301 at a constant rate to rotate the air discharge port 250 at a constant speed with a rotation axis perpendicular to the floor of the room IN as the rotation center. . For example, the reduction gear 302 is coupled to the first gear 302-1 coupled to the rotation center axis 301-1 of the rotation unit 301, and the rotation center axis 251 of the air discharge port 250. A second gear 302-2 meshing with the first gear 302-1, and the first and second gears 302-1, 302-2 of the reduction gear 302 rotate the rotation unit 251. The speed is reduced to a ratio of 100: 1 to rotate the air outlet 250 at a constant speed. As described above, when the air discharge port 250 corresponds to the air speed by the air discharge port rotating part 300, that is, the speed of the air passing through the speed increase hopper 260 is relatively slow, the rotating unit 301 rotates slowly. When the air discharge port 250 rotates slowly, and the speed of the air passing through the speed increase hopper 260 is relatively high, the rotary unit 301 rotates rapidly, and the air discharge port 250 rotates rapidly, thereby reducing the overall interior IN. The air may be uniformly and uniformly cooled regardless of the distance from the air outlet 250. Meanwhile, the air discharge port rotating unit 300 includes a rotation drive unit (not shown) including a motor and a drive shaft (not shown) for providing a rotation driving force of the rotation drive unit to the rotation center axis 251 of the air discharge port 250. It may be made of). That is, although the air discharge port 250 may be rotated by the discharged air, the air discharge port 250 may be forcibly rotated by the rotation driving unit including the motor. In addition, the air discharge port 250 may rotate at a rotational speed of substantially 0.5 to 1.0 times per minute.
