It relates to a suction structure of the package air conditioner to increase the heat exchange rate.
일반적으로 에어콘은 압축된 냉매가 팽창되면서 발생하는 감열작용을 이용하여 실내로부터 흡입된 공기를 냉각시키고, 이 냉각된 공기를 실내로 토출시킴으로써, 냉방을 하게 된다.In general, the air conditioner cools the air sucked from the room by using a thermal action generated by the expansion of the compressed refrigerant, and discharges the cooled air into the room, thereby cooling.
도 1은 일반적인 패키지 에어콘의 구조를 도시한 종단면도로서, 에어콘은 실외에 설치되어 냉매를 압축시키고, 압축된 냉매를 액체화시키는 실외기(미도시함)와, 팽창 밸브에 의한 압력강하작용으로 냉매의 온도를 낮추어 주위 공기를 냉각시키는 실내기로 이루어진다.1 is a vertical cross-sectional view showing the structure of a general package air conditioner, the air conditioner is installed outdoors to compress the refrigerant, and the outdoor unit (not shown) to liquefy the compressed refrigerant and the pressure drop action of the refrigerant by the expansion valve It consists of an indoor unit that cools the surrounding air by lowering the temperature.
여기에서, 실내기는 베이스(2)의 상부로 내부에 공간을 갖도록 하는 캐비닛(4)과, 캐비닛(4)의 전면에 흡입용 그릴(8)이 구비된 커버(6)와, 커버(6)의 상단부에 냉각된 공기를 토출시키는 토출그릴(10)로 구성된다.Here, the indoor unit is a cabinet 4 having a space inside the upper part of the base 2, a cover 6 provided with a suction grill 8 on the front of the cabinet 4, and a cover 6. The discharge grill 10 for discharging the cooled air to the upper end of the.
커버(6)와 캐비닛(4)이 제공하는 공간부는 흡입용 그릴(8)에 가까이 증발기(12)가 설치되어 있고, 증발기(12)의 하단에는 열교환과정에서 발생되는 응축수를 배출시키는 응축수 배출부(14)가 설치되어 있다.The space provided by the cover 6 and the cabinet 4 is provided with an evaporator 12 near the suction grill 8, and a condensate discharge part for discharging condensate generated during the heat exchange process at the lower end of the evaporator 12. (14) is provided.
증발기(12)의 하부에는 실내 공기를 흡입하고, 흡입된 공기를 토출그릴(10)을 통해 실내로 배출시키는데 필요한 흡입, 토출력을 제공하는 송풍장치가 설치되어 있다. 송풍장치는 시로코 팬(20)이 모터(22)에 의해 회전 가능하게 고정되어 있으며, 시로코 팬(20)은 유입부(18a)와 토출부(18b)가 구비된 케이싱(18)내에 설치되어 있고, 케이싱(18)은 체결수단으로 캐비닛(4)에 고정되어 있다.In the lower part of the evaporator 12, a blower is provided that sucks indoor air and provides suction and earth output required for discharging the sucked air into the room through the discharge grill 10. In the blower, the sirocco fan 20 is rotatably fixed by the motor 22, and the sirocco fan 20 is installed in the casing 18 provided with the inlet portion 18a and the discharge portion 18b. The casing 18 is fixed to the cabinet 4 by fastening means.
이러한 에어콘은 캐비닛(4)내에 있는 모터(22)에 의해 시로코 팬(20)이 구동됨으로써, 케이싱(18)의 유입부(18a)를 통해 하부에 있는 공기가 토출부(18b)를 경유하여 상부에 설치된 증발기(12)를 통과하는 과정 냉각된 상태로 토출그릴(10)을 통해 실내로 배출된다.The air conditioner is driven by the motor 22 in the cabinet 4 so that the sirocco fan 20 is driven so that the air at the bottom through the inlet portion 18a of the casing 18 passes through the discharge portion 18b. The process of passing through the evaporator 12 installed in the discharged to the room through the discharge grill 10 in a cooled state.
그러나, 실내 공기가 하우징내에 설치된 블로워를 통과하는 과정에서 흡입그릴을 통과한 공기가 90°꺾이어 유입됨으로써, 블로워 하단에 와류현상이 일어나게 되어 흡입소음이 발생하게 되고, 이로 인해 열교환율과 냉방효율이 낮아지게 되는 문제점이 있다.However, when indoor air passes through the blower installed in the housing and the air passing through the suction grille is introduced by 90 °, vortex phenomena occur at the bottom of the blower, resulting in inhalation noise, which causes heat exchange rate and cooling efficiency. There is a problem that is lowered.
따라서, 본 고안은 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 블로워의 하단에 캐비닛의 횡방향을 갖도록 하는 가이드를 설치하여 와류발생을 제거함으로써, 실내기 내로 유입되는 공기의 유속과 그 량을 일정하게 하여 흡입소음을 줄이고, 열교환율과 냉방효율을 높이도록 하는 패키지 에어콘의 흡입구조를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised to solve such a problem, and by installing a guide having a transverse direction of the cabinet at the lower end of the blower to eliminate the vortex generation, the flow rate of the air flowing into the indoor unit and the amount of the constant The purpose of the present invention is to provide a suction structure of a package air conditioner to reduce suction noise and increase heat exchange rate and cooling efficiency.

It is achieved by providing a suction structure of.
이하, 본 고안의 실시예를 첨부 도면을 참조하여 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
도 2는 본 고안에 따른 흡입구조를 채용한 패키지 에어콘의 종단면도이고, 도 3은 본 고안에 따른 흡입구조에 채용된 가이더의 사시도이다.2 is a longitudinal cross-sectional view of a package air conditioner employing a suction structure according to the present invention, Figure 3 is a perspective view of the guider employed in the suction structure according to the present invention.
먼저, 본 실시예를 설명함에 앞서, 종래와 연계하여 설명하면, 도 1에 도시된 바와 같이, 에어콘은 베이스(2)와, 베이스(2)의 상부로 송풍장치와 증발기(12)가 내설된 캐비닛(4)과, 캐비닛(4)의 전면에 흡입그릴(8)과 토출그릴(10)이 설치된 커버(6)로 이루어진다.First, prior to the present embodiment, when described in connection with the prior art, as shown in Figure 1, the air conditioner is a base 2, the blower and the evaporator 12 is built in the upper portion of the base (2) It consists of a cabinet 4 and a cover 6 provided with a suction grill 8 and a discharge grill 10 on the front surface of the cabinet 4.
여기에서, 송풍장치는 증발기(12)의 하부에 설치되어 실내공기를 흡입하고, 이 흡입된 공기를 증발기(12)로 공급하도록 하는 것으로, 모터(22)에 회전되는 시로코 팬(20)에 의해 공기를 흡입하고, 토출시키도록 되어 있다.Here, the blower is installed in the lower part of the evaporator 12 to suck indoor air, and to supply the sucked air to the evaporator 12, by the sirocco fan 20 rotated to the motor 22. The air is sucked in and discharged.
이러한 실내기에 있어서, 냉방시는 시로코 팬(20)의 구동에 의해 케이싱(18)의 흡입부(18a)를 통해 실내 공기가 유입되고, 토출부(18b)를 통해 배출된 공기가 증발기(12)를 통과하면서 냉각되고, 이 냉각된 공기가 토출그릴(10)을 통해 실내로 배출됨으로써, 냉방을 하게 된다.In this indoor unit, indoor air is introduced through the suction part 18a of the casing 18 by the driving of the sirocco fan 20 while the air is discharged, and the air discharged through the discharge part 18b is evaporator 12. Cooled while passing through, the cooled air is discharged into the room through the discharge grill 10, thereby cooling.
이와 같이, 시로코 팬(20)의 구동으로 발생되는 흡입력에 의해 흡입그릴(8)을 통해 캐비닛(4)내로 공기가 유입되고, 이어 케이싱(18)으로 유입되는 과정에서 유입된 공기의 일부가 케이싱(18)의 하단과 베이스(2)가 제공하는 공간내로 유입되어 와류가 발생되는 것을 방지하도록 본 고안에서 시로코 팬(20)을 내설한 케이싱(18) 하부로 공기가 흐르게 되는 것을 차단하는 와류억제수단(17)을 설치하였다.As such, air is introduced into the cabinet 4 through the suction grill 8 by the suction force generated by the driving of the sirocco fan 20, and then a part of the air introduced in the process of being introduced into the casing 18 is casing. Vortex suppression that blocks air from flowing down the casing 18 incorporating the sirocco fan 20 in the present invention to prevent vortices from entering the space provided by the lower end of the base 18 and the base 2. The means 17 were installed.
본 발명의 바람직한 실시예는 도 3에 도시된 바와 같이, 이와류억제수단(17)은 소정의 곡률을 갖도록 하는 만곡형 플레이트(17a)와, 이 플레이트(17a)의 양단에 캐비닛(4)의 측벽에 고정하도록 체결공(17b-1)을 형성한 고정부(17b)를 일체로 형성한다.According to a preferred embodiment of the present invention, as shown in Fig. 3, the airflow control means 17 has a curved plate 17a having a predetermined curvature, and the cabinet 4 at both ends of the plate 17a. The fixing part 17b in which the fastening hole 17b-1 was formed to be fixed to the side wall is integrally formed.
또한, 반곡형 플레이트(17a)의 윗면에 다수의 수직 가이드를 설치하여 유입되는 공기가 옆방향으로 퍼지게 되는 것을 방지하도록 하는 것이 바람직하다.In addition, it is preferable to install a plurality of vertical guides on the upper surface of the semi-curved plate 17a to prevent the incoming air from spreading laterally.
이와 같이, 시로코 팬(20)의 원심력에 의해 실내 공기는 흡입그릴(8)을 통해 캐비닛(4)내로 유입되고, 이어 케이싱(18)의 중앙을 통해 그 내부로 유입되는데 케이싱(18)의 하단에 횡방향의 만곡형 플레이트(17a)의 윗면을 흐르게 된다.As such, the indoor air is introduced into the cabinet 4 through the suction grill 8 by the centrifugal force of the sirocco fan 20, and then introduced into the cabinet 4 through the center of the casing 18. The upper surface of the curved plate 17a in the transverse direction flows.
그 결과, 케이싱(18)으로 유입되는 공기의 일부가 베이스측으로 흐르게 되는 것을 방지하게 된다.As a result, a part of the air flowing into the casing 18 is prevented from flowing to the base side.
이상에서 살펴 본 바와 같이, 본 고안은 흡입그릴의 내측 만곡형 플레이트를 횡방향으로 설치함으로써, 유입된 공기의 일부가 케이싱의 외측 또는 하부로 흐르게 되는 것을 방지함으로써, 와류로 인한 유동소음을 줄이도록 하는 이점이 있다.As described above, the present invention by installing the inner curved plate of the suction grill in the transverse direction, by preventing a part of the inflowed air to flow to the outside or bottom of the casing, to reduce the flow noise due to vortex This has the advantage.
