Abstract

PURPOSE: An indoor unit of ceiling type air conditioner is provided to reduce noise in comparison to blast capacity and to uniformly distribute chilled air. CONSTITUTION: A chilled air flowing space(10d) formed between an evaporator(14) and an outer wall of a case(10) in the case is formed so that sectional area thereof increases as nearer to an outlet(10b) at fixed angle(alpha). Flow rate of the chilled air sucked into the case by a blowing fan(12) is decreased as the chilled air passes the evaporator, flows into the chilled air flowing space and moves to the outlet thereby to reduce noise generated in the outlet while increasing blast capacity.

Description

천장형 에어컨의 실내기{Ceiling mounted indoor unit of Air conditioner}Ceiling mounted indoor unit of Air conditioner

본 발명은 에어컨에 관한 것으로, 보다 상세하게는 천장형 에어컨의 실내기에 관한 것이다.The present invention relates to an air conditioner, and more particularly to an indoor unit of a ceiling type air conditioner.

일반적으로 분리형 에어컨은 증발기를 통해 실내공기의 냉각 순환작용을 수행하는 실내기와 응축기를 통해 상기 증발기에서 유동된 냉매의 냉각 작용을 수행하는 실외기가 별도로 분리된 구조로서, 실내기의 설치방식에 따라 액자형과, 직립형, 천장형 등으로 구분된다.In general, a separate air conditioner is a structure in which an indoor unit performing a cooling circulation of indoor air through an evaporator and an outdoor unit performing a cooling action of the refrigerant flowed from the evaporator through a condenser are separately separated. , Upright, ceiling, etc.

상기 천장형 에어컨은 도 1에 나타난 것과 같이 건물의 천장(C)에 삽입 설치되는 케이스(10) 및 케이스(10) 내에 장착된 송풍팬(12)과, 상기 송풍팬(12)의 측면에 구비된 증발기(14), 송풍팬(12)의 작동을 위한 구동모터(16)를 포함하여 이루어져 있다.The ceiling air conditioner is provided in the case 10 and the blowing fan 12 mounted in the case 10 and inserted into the ceiling (C) of the building as shown in Figure 1, the side of the blowing fan 12 It comprises a drive motor 16 for the operation of the evaporator 14, the blowing fan 12.

여기서, 상기 송풍팬(12)은 원심팬의 일종으로서, 슈라우드(121)와, 상기 슈라우드(121)에 부착된 다수개의 블레이드(122)로 이루어져 있으며, 상기 슈라우드(121)와 케이스 (10)중앙의 흡입구 사이에는 벨마우스(101)가 구비되어 있다.Here, the blowing fan 12 is a kind of centrifugal fan, which is composed of a shroud 121 and a plurality of blades 122 attached to the shroud 121, the center of the shroud 121 and the case 10 Bell mouth 101 is provided between the inlets of the.

그리고, 증발기(14)는 송풍팬(12)의 좌우 양 측방에 구비되어 있고, 케이스(10)의 외곽에는 벨마우스(101) 중심의 흡입구(10a)를 통해 흡입된 공기가 토출되는 토출구(10b)가 형성되어 있다.And, the evaporator 14 is provided on both sides of the blower fan 12, the discharge port 10b for discharging the air sucked through the inlet port 10a of the center of the bell mouse 101 on the outside of the case 10 ) Is formed.

여기서, 상기 토출구(10b)는 케이스(10)의 외벽과 증발기(14) 사이의 이른바 냉기유동공간(10c) 선단에 형성되어 있으며, 상기 냉기유동공간(10c)의 단면적은 토출구(10b)의 면적과 거의 동일하게 유지된다.Here, the discharge port 10b is formed at the tip of the so-called cold air flow space 10c between the outer wall of the case 10 and the evaporator 14, and the cross-sectional area of the cold air flow space 10c is the area of the discharge port 10b. And remain almost the same.

이러한 천장형 에어컨의 실내기에 의하면 상기 송풍팬(12)이 구동모터(16)에 의해 회전 작동함으로써, 실내공기의 더운공기가 흡입구(10a)를 통해 케이스(10) 내로 흡입되어 증발기(14)를 거치면서 냉각되고, 냉각된 공기가 냉기유동공간(10c)을 거친 다음 토출구(10b)를 통해 케이스(10) 밖으로 배출됨으로써 실내의 기온이 적절하게 냉방 조절된다.According to the indoor unit of the ceiling-type air conditioner, the blowing fan 12 is rotated by the driving motor 16, so that the hot air of the indoor air is sucked into the case 10 through the intake port 10a and the evaporator 14 is removed. While cooling, the cooled air passes through the cold air flow space 10c and then is discharged out of the case 10 through the discharge port 10b so that the air temperature of the room is appropriately cooled.

이때 에어컨 실내기의 설치위치상 케이스(10)의 외부로 배출된 냉기는 상온의 외기에 비해 온도가 낮은 특성상 자연스럽게 아래로 퍼지기 때문에, 송풍팬(12)의 토출압을 높이지 않더라도 비교적 효과적인 냉방이 가능하다고 볼 수 있다.At this time, since the cold air discharged to the outside of the case 10 in the installation position of the air conditioner indoor unit naturally spreads down due to the low temperature compared to the ambient air at room temperature, relatively effective cooling is possible even without increasing the discharge pressure of the blower fan 12. It can be said that.

한편, 상술한 바와 같은 종래기술에 의하면 흡입구(10a)를 통해 케이스(10) 내로 흡입된 공기가 송풍팬(12)을 중심으로 좌우로 분산되어 면적이 작은 토출구(10b)를 통해 토출되므로, 케이스(10) 내에서의 공기의 유동이 단방향으로 이루어지는 다른 타입의 에어컨에 비해 풍량이 같은 경우에도 냉기의 유속이 빠르게 형성된다.On the other hand, according to the prior art as described above, the air sucked into the case 10 through the suction port (10a) is distributed to the left and right around the blower fan 12 is discharged through the small discharge port (10b), the case The flow rate of cold air is formed rapidly even when the air volume is the same as that of other types of air conditioners in which the flow of air in (10) is unidirectional.

따라서, 이러한 종래 천장형 에어컨의 실내기에 의하면 냉기의 유속이 빠르기 때문에 작동 시에 소음이 크게 발생하는 반면 풍량이 많지 않기 때문에 냉기가 실내 공간에 고르게 확산되지 않는다는 문제점이 발생한다.Therefore, according to the indoor unit of the conventional ceiling-type air conditioner, since the flow rate of the cold air is high, noise is largely generated during operation, but the air volume is not large, and thus there is a problem that the cold air is not evenly spread in the indoor space.

본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 토출구의 단면적이 점차 커지는 구조로 이루어짐으로써 풍량대비 소음이 감소되고 냉기가 고루확산되도록 하는 천장형 에어컨의 실내기 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned conventional problems, it is an object of the indoor unit of the ceiling-type air conditioner to reduce the noise compared to the air volume and to evenly spread the cold air by being made of a structure in which the cross-sectional area of the discharge port is gradually increased.

상기 목적을 달성하기 위하여 제공되는 천장형 에어컨의 실내기는 건물의 천장에 삽입 설치되는 케이스 및 케이스 내에 장착된 송풍팬과, 상기 송풍팬의 측면에 구비된 증발기, 송풍팬의 작동을 위한 구동모터를 포함하며; 상기 케이스 내에서 증발기와 케이스 외벽과의 사이에 형성되는 냉기유동공간이 토출구 측으로 갈수록 단면적이 확장되는 형태로 이루어지는 것을 특징으로 한다.An indoor unit of a ceiling type air conditioner provided to achieve the above object includes a case inserted into a ceiling of a building and a blower fan mounted in the case, an evaporator provided at a side of the blower fan, and a driving motor for operating the blower fan. Includes; The cold air flow space formed between the evaporator and the case outer wall in the case is characterized in that the cross-sectional area is formed to extend toward the discharge port side.

이하, 본 발명의 실시예를 첨부된 도 2를 참조로 하여 상세하게 설명하며, 본 발명의 내용 중 종래구성과 동일한 부분에 대해서는 동일한 부호를 부여하기로 한다.DETAILED DESCRIPTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the same reference numerals will be given to the same parts as those in the prior art.

우선, 본 발명의 실시예에 따른 천장형 에어컨의 실내기는 도면에 나타난 것과 같이 건물의 천장에 삽입 설치되는 케이스(10) 및 케이스(10) 내에 장착된 송풍팬(12)과, 상기 송풍팬(12)의 측면에 구비된 증발기(14), 송풍팬(12)의 작동을 위한 구동모터(16)를 포함하여 이루어진다.First, the indoor unit of the ceiling-type air conditioner according to the embodiment of the present invention, as shown in the drawing, the case 10 and the blowing fan 12 mounted in the case 10 and installed in the ceiling of the building, and the blowing fan ( It comprises a drive motor 16 for the operation of the evaporator 14, the blowing fan 12 provided on the side of 12).

여기서, 상기 케이스(10) 내에서 증발기(14)와 케이스(10) 외벽과의 사이에 형성되는 냉기유동공간(10d)은 토출구(10b) 측으로 갈수록 단면적이 일정한 각도(a) 만큼 확장되는 형태로 이루어진다.Here, the cold air flow space (10d) formed between the evaporator 14 and the outer wall of the case 10 in the case 10 has a cross-sectional area extending toward the discharge port (10b) by a certain angle (a) Is done.

따라서, 본 발명의 실시예에 의하면 송풍팬(12)의 작동에 의해 케이스(10) 내로 흡입된 냉기가 증발기(14)를 통과하여 냉기유동공간(10d)으로 유입된 다음 토출구(10b)로 이동하는 과정에서 유속이 감소하기 때문에 토출구(10b)에서의 소음이 줄어들게 된다.Therefore, according to the embodiment of the present invention, the cold air sucked into the case 10 by the operation of the blower fan 12 passes through the evaporator 14, enters the cold air flow space 10d, and then moves to the discharge port 10b. Since the flow rate is reduced in the process, the noise at the discharge port 10b is reduced.

유속이 감소하는 대신 풍량이 늘어나기 때문에 냉기가 골고루 확산되어 냉방효율은 저하되지 않는다.Cooling air is spread evenly because the airflow increases instead of decreasing the flow rate, so the cooling efficiency does not decrease.

이상에서 설명한 바와 같이 본 발명에 따른 천장형 에어컨의 실내기에 의하면 토출구가 확장되어 냉기의 풍량이 늘어남과 동시에 유속이 감소됨으로서 소음이줄어들고 냉기가 고루 확산되기 때문에 보다 쾌적한 냉방상태를 유지할 수 있다는 이점이 있다.As described above, according to the indoor unit of the ceiling-type air conditioner according to the present invention, since the discharge port is expanded and the air volume of the cold air is increased and the flow rate is reduced, the noise is reduced and the cold air is spread evenly. have.
