Description

Technology Field

[0001] The present invention relates to an indoor unit for cooling a room, and more specifically, to an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency, which prevents condensation from entering the room and prevents a decrease in cooling efficiency caused by condensation by introducing air from the side, passing it through a heat exchanger, and then discharging the cooled air from the top or upper side, and which improves cooling efficiency by expanding the air contact area by a cooler provided at an angle. Background Technology

[0002] Generally, indoor units that cool the interior are equipped in a form where outside air is drawn in from the side or top, passes through a heat exchanger, and is discharged downwards.

[0003] Consequently, condensation occurs due to the cooled air, and as the generated condensation is typically discharged through a drain pipe or drain plate formed on the side, a problem arises where the condensation is discharged into the room along with the cooled air.

[0004] In addition, as air passes through the heat exchanger in a straight line during the inflow and outflow paths, a large amount of air passes through the heat exchanger together, increasing the load on the heat exchanger and consequently causing a problem of reduced cooling efficiency.

[0005] Furthermore, when the incoming air passes through the heat exchanger, condensation formed on the heat exchanger hinders the smooth flow of air and causes a problem where heat exchange efficiency is also reduced.

[0006] In this regard, prior art document 1 (Registered Patent 10-2284081 Ventilation-type air purifier and ventilation system equipped therewith) discloses a configuration in which an indoor unit discharges air from the top to the bottom side of a ventilation-type air purifier.

[0007] However, in Prior Art 1, when condensation occurs, it falls downward due to its own weight, so a problem arises in which condensation can enter the room through the air supply pipe. Prior art literature

[0030] The present invention relates to an airflow diffusion type indoor unit, and is characterized in that, in particular, by introducing outside air from the side and discharging it upward, it is possible to prevent condensation from being discharged together, and by installing the heat exchanger at an angle to increase heat exchange efficiency, and by providing a drain plate at the bottom of the heat exchanger to facilitate the discharge of condensation.

[0031] Hereinafter, an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to one embodiment of the present invention will be described in detail with reference to the attached drawings.

[0032] FIG. 1 is an overall perspective view of an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to an embodiment of the present invention, and FIG. 2 is a perspective view showing the state with the cover removed from an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to an embodiment of the present invention.

[0033] Referring to FIGS. 1 and 2, the present invention comprises an outer casing (100) installed in an upright structure indoors, a blower (200) embedded in the outer casing (100) that induces outside air to be introduced from the side of the outer casing (100) by rotational driving and blown to the top of the outer casing (100), and a heat exchanger (300) provided on a path through which outside air introduced from the side of the outer casing (100) flows toward the blower (200) to cool the outside air through heat exchange.

[0034] It is configured to include an air discharge damper (400) installed to extend from the upper part of the outer casing (100) to a position higher than the blower (200) and heat exchanger (300) to discharge cooled air back into the room.

[0035] In addition, the lower part of the heat exchanger (300) is configured to include a drain plate (500) that recovers condensate generated during the heat exchange process, collects it in one place, and discharges it.

[0036] Here, the outer casing (100) is configured to include an outside air inlet (110) into which outside air is introduced at a lower position in the lateral direction of the outer casing (100), and an air distributor (120) that allows the introduced air to be cooled through the heat exchanger (300), pass through a blower (200), and be distributed to the upper part of the outer casing (100) and discharged.

[0037] At this time, on one side of the outer casing (100), a cover (130) that can be opened and closed is provided to maintain and repair the interior from the outer casing (100).

[0038] The above-mentioned external air inlet (110) is capable of filtering foreign substances when external air is introduced, and is configured to include a pre-filter (111) that filters relatively large foreign substances and a medium filter (112) that filters relatively small foreign substances not filtered by the pre-filter (111).

[0039] These external air intake sections (110) can be used by installing various types of filters for air purification as needed.

[0040] The above air distributor (120) is provided to extend upward from the top of the outer casing (100), and can discharge air upward by means of an air discharge pipe (121) that is able to discharge air that has been cooled by flowing into the outer casing (100) and passing through the heat exchanger (300) at a high position.

[0041] And it is configured to include a multi-stage distribution slot (122) provided in the shape of a cap consisting of multiple stages at the upper end of the air discharge pipe (121) to distribute and discharge the discharged air in multiple stages.

[0042] The above multi-stage distribution slot (122) is configured to gradually become smaller towards the top, so that air can be efficiently discharged according to the air discharge pressure.

[0043] At this time, a plurality of exhaust holes (123) are formed on the inner side of the multi-stage distribution slot (122) so that air discharged through the air exhaust pipe (121) is exhausted.

[0044] As a result, the air introduced by the blower (200) is discharged to the upper side, preventing condensation caused by condensation from entering the room along with the airflow, thereby enabling efficient cooling.

[0045] The blower (200) is configured to include a blower inlet (210) installed inside the outer casing (100) and rotated by power to pressurize and send outside air into the outer casing (100), and a blower discharge (220) provided above the blower inlet (210) to discharge air toward the upper side.

[0046] And between the air intake section (210) and the air exhaust section (220), it is configured to include an impeller (230) that is rotated by the power of a motor (not shown) and generates pressure for external air to be introduced and discharged by rotation.

[0047] The above heat exchanger (300) is capable of cooling passing air by heat exchange and is configured to include a heat exchange coil (310) through which a refrigerant circulates, and heat dissipation fins (320) arranged in a thin plate shape along the area where the heat exchange coil (310) is provided, which can increase the heat exchange efficiency when air passes through the heat exchange coil (310).

[0048] And at the bottom of the heat exchanger (300), an inclined fixing part (330) is provided so that the heat exchanger (300) can be installed at an angle in the path where air moves.

[0049] As a result, the contact area of ​​the air passing through the heat exchanger (300) is increased, thereby maximizing cooling efficiency.

[0050] The air discharge damper (400) is configured to allow cooled air to be discharged along with the air distributor (120) side and also to the upper side of the outer casing (100), and includes a side four-way damper (410) which is configured to be openable and closable from the top of the outer casing (100) toward the outside and selectively discharge air in four directions.

[0051] And it is configured to include an upper discharge damper (420) provided on the side of the air distributor (120) and capable of controlling the opening and closing of the air discharged upward.

[0052] Meanwhile, the air exhaust damper (400) may be equipped with a plurality of air blower guide blades (430) capable of inducing airflow.

[0053] The above-mentioned blower guide blade (430) is configured to include a fixed blade (431) installed in a fixed state at the upper and lower parts of the damper and a rotating blade (432) that allows the user to adjust the blower direction as intended by rotating operation.

[0054] At this time, the rotating blade (432) is provided with an operating protrusion (432a) that protrudes on both sides, allowing the user to adjust the angle of the rotating blade (432) by hand, so that the user can easily adjust the angle and use it.

[0055] The drain plate (500) is configured to include a condensate recovery plate (510) provided at the bottom of the heat exchanger (300) for collecting and recovering condensate generated during the heat exchange process, and a condensate discharge hole (520) provided on one side of the condensate recovery plate (510) for discharging the recovered condensate.

[0056] As a result, when condensation occurs, it falls due to its own weight and is collected by the condensation recovery plate (510), and the collected condensation is guided to the condensation discharge hole (520) on one side and discharged, thereby collecting the condensation in the opposite direction to the upward direction of the airflow direction, so that the condensation can be prevented from flowing into the room.

[0057] FIG. 3 is an operation state diagram illustrating the state in which air is introduced and discharged in an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to an embodiment of the present invention.

[0058] Referring to FIG. 3, when the blower (200) is operated, outside air is introduced through the outside air inlet (110) formed on one side of the outer casing (100).

[0059] The incoming outside air is filtered of foreign substances by the pre-filter (111) and the medium filter (112) and is introduced, moves toward the blower (200) side by the rotational force of the blower (200), and passes through the heat exchanger (300).

[0060] At this time, the heat exchanger (300) is installed at an angle, and is installed to maximize the amount of contact with air between the blower (200) side and the outside air inlet (110) along the direction of air flow.

[0061] As a result, outside air passes through the heat exchanger (300) and is cooled by heat exchange, and the cooled air passes through the blower (200) and moves upward.

[0062] The air moved upward by the blower (200) is selectively moved sideways or upward through the air discharge damper (400), and passes through the air distributor (120) at the top of the outer casing (100), thereby supplying cold air to the room in all directions, enabling efficient cooling.

[0063] FIG. 4 is an embodiment illustrating a state in which a condensate removal member capable of removing condensate from a heat exchanger is further provided in an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to another embodiment of the present invention, and FIG. 5 is an enlarged view illustrating in detail the condensate removal member in an upward discharge airflow diffusion type indoor unit with excellent condensation prevention and improved cooling efficiency according to another embodiment of the present invention.

[0064] Referring to FIGS. 4 and 5, the heat exchanger (300) may further be provided with a condensate removal member (600) that rotates by the movement of the blower and strikes the heat exchange coil, thereby causing the condensate to be separated from the heat exchanger by the vibration caused by the strike and fall toward the drain plate (500).

[0065] The above condensate removal member (600) may be configured to include a striking member (610) that strikes the heat exchange coil (310) provided at a location where the heat exchange coil (310) is installed, and a rotational support member (620) that supports the striking member (610) so as to be rotatable.

[0066] At this time, the condensate removal member (600) may be configured to include a detachable clip (630) that can detach the condensate removal member (600) from the heat exchanger (300).

[0067] The detachable clip (630) is provided so that the condensate removal member (600) can be removed to minimize noise during dry weather when there is relatively little condensation, and then selectively attached to use the condensate removal member (600) during rainy weather or when humidity is high.

[0068] Here, the striking member (610) is configured to include a striking part (611) that is rotated away from the heat exchange coil (310) and then falls due to its own weight to strike the heat exchange coil (310), thereby directly colliding with the heat exchanger (300) and applying impact to separate the condensate from the heat exchange coil (310).

[0069] And it is configured to include an extension bar (612) that extends in a bar shape from the striking part (611) toward the rotating support member (620) and increases the rotational centrifugal force by separating the distance from the rotating support member (620) to the striking part (611).

[0070] At this time, the extension bar (612) is configured to include resistance wings (613) that are provided on both sides to form protruding wing shapes, thereby generating resistance due to the movement of the blower and causing the striking member (610) to rotate upward.

[0071] The above resistance wing (613) may be configured to include a blower-guiding inclined surface (613a) formed at the lower part in contact with the blower so as to be inclined along the direction of movement of the blower, thereby inducing the blower to pass quickly through the resistance wing (613).

[0072] The above-mentioned air blower guiding slope (613a) is formed to become thinner and sharper along the air blower path, so that the resistance is released as the air blower moves the striking member (610) upward and then moves away. As the air blower moves, the striking member (610) repeatedly rotates and strikes the heat exchange coil (310), allowing the condensate to be removed by impact.

[0073] These striking members (610) are made of a soft material such as silicone or rubber, and their weight is minimized to facilitate rotation by airflow and to minimize noise when striking.

[0074] The present invention, as described above, allows for the cooling of outside air for indoor cooling by introducing outside air from the side and allowing it to pass from the bottom to the top of the heat exchanger, thereby preventing condensation from being discharged along with the airflow. Additionally, the heat exchanger is provided at an angle along the outside air movement path to maximize the surface area of ​​contact between the outside air and the heat exchanger, thereby increasing cooling efficiency.

[0075] In addition, a drain plate is installed at the bottom of the heat exchanger to collect condensate and allow for convenient discharge. Explanation of the symbols
