Description
본 발명은 온풍 벤치에 관한 것으로서, 더욱 상세하게는 벤치 내부에 PTC소자를 이용한 온풍발생기를 설치하여 이용자가 없을 때에는 좌판을 온풍으로 예열시켜서 겨울철 앉는데 불편하지 않도록 하고 특히 좌판에 앉으면 열풍이 이용자 쪽으로 향하게 조절함으로써, 열기를 빠르게 체감할 수 있도록 한 온풍 벤치를 제공함에 있다.The present invention relates to a warm air bench, and more particularly, by installing a warm air generator using a PTC element inside the bench to preheat the seat with warm air when there is no user, so that it is not uncomfortable to sit on in winter, and especially when sitting on the seat, hot air is directed toward the user. It is to provide a warm air bench that allows you to quickly feel the heat by adjusting the direction.
일반적으로 공공장소, 공원 및 정류소 등에 설치되는 긴 의자는 사람들이 앉아서 휴식을 취할 수 있도록 옥외에 설치되는데, 각 지방자치단체는 휴식공간을 제공하기 위해 다양한 형태의 의자를 설치하고 있는 추세이다. 하지만 기존의 의자는 기온이 매우 높은 하절기에는 좌석이 뜨겁고, 기온이 매우 낮은 동절기 특히 야간의 경우에는 좌석이 매우 차갑기 때문에 잘 사용하지 않는 문제점이 있었다.In general, long chairs installed in public places, parks, and bus stops are installed outdoors so that people can sit and take a break, and each local government tends to install various types of chairs to provide a resting space. However, existing chairs have a problem in that they are not used well because the seats are hot during the summer when the temperature is very high and the seats are very cold during the winter when the temperature is very low, especially at night.
이를 감안하여 종래 특허 제1929936호는 펠티어효과를 내는 열전소자로 냉각블럭을 냉각시키고, 상기 냉각블럭으로 냉매가 순환되는 냉각관 표면에 바람을 공급하여 냉풍이 의자로 토출되도록 한 냉풍벤치를 제안하 바 있다.In view of this, prior patent No. 1929936 proposes a cooling air bench in which a cooling block is cooled with a thermoelectric element that produces a Peltier effect, and wind is supplied to the surface of a cooling pipe through which a refrigerant circulates through the cooling block so that the cold air is discharged to a chair. there is a bar
그러나 종래 특허는 냉풍을 일으키기 위하여 냉각관과 냉매가 필요하고, 냉매를 순환시키는 펌프가 필요하므로 구조가 복잡하고, 또한 열전소자에서 냉각이 이뤄지는 동안 반대쪽에서 고열이 발생되는데, 외기를 불어서 공냉시키는 구조이므로 여름철 외기온도가 높아지는 혹서기에는 방열기능이 떨어져 상대적으로 냉각효율이 저하되는 등의 문제점이 있었다.However, the conventional patent requires a cooling pipe and a refrigerant to generate cold air, and a pump to circulate the refrigerant, so the structure is complicated, and high heat is generated on the other side while cooling in the thermoelectric element. Therefore, in the hot summer season when the outdoor temperature is high, the heat dissipation function is lowered and the cooling efficiency is relatively lowered.
국내 공개특허 제2017-0002952호는 좌판 또는 등판에 열전소자를 설치하여 주위온도에 따라 냉열 작동하도록 한 열전소자 의자를 제안한 바 있다.Korean Patent Publication No. 2017-0002952 proposes a thermoelectric chair in which a thermoelectric element is installed on a seat or a backrest to cool and heat according to the ambient temperature.
그러나 종래특허는 전류방향을 바꿔서 하나의 열전소자로 여름철에는 좌판을 냉각시키고 겨울철에는 가열시키도록 구성하였으나, 여름철 한쪽 면이 냉각되는 동안 반대쪽에서 발생되는 고열을 빠르게 낮춰야 냉각이 지속되는 열전소자의 특성을 감안할때 열을 방출시키는 히트싱크 등의 구성이 없고, 단순히 공기 중에 노출된 정도만으로 열을 낮추는 것은 한계가 있으므로 냉각효율이 떨어지는 등의 기술적인 문제점이 있었다.However, the conventional patent is configured to change the direction of the current and use one thermoelectric element to cool the seat in summer and heat it in winter, but the characteristics of the thermoelectric element in which cooling continues only when the high heat generated on the other side is quickly lowered while one side is cooled in summer. Considering that there is no configuration such as a heat sink for dissipating heat, and there is a limit to simply lowering the heat only to the extent of exposure to the air, there are technical problems such as low cooling efficiency.
본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 벤치 내부에 PTC소자를 이용한 온풍발생기를 설치하여 이용자가 없을 때에는 좌판을 온풍으로 예열시켜서 겨울철 앉을 수 있도록 하고 특히 좌판에 앉으면 열풍이 이용자 쪽으로 향하게 조절함으로써, 열기를 빠르게 체감할 수 있도록 한 온풍 벤치를 제공함에 있다.The present invention was developed in view of the problems of the prior art, and an object of the present invention is to install a warm air generator using a PTC element inside the bench to preheat the seat with warm air when there is no user so that it can be seated in winter, especially when sitting on the seat. It is to provide a warm air bench so that the user can quickly feel the heat by adjusting it toward the user.
이를 위하여 본 발명 한 실시예는 여러명이 떨어져 앉을 수 있는 좌판을 갖는 중공상의 몸체 내부에 다수의 덕트가 이용자가 앉는 자리마다 떨어져 구비되고; 각 상기 덕트는 윗면이 개방되어서 상기 좌판의 밑면에 직접 노출되며; 각 상기 덕트의 입구는 PTC소자를 갖는 온풍발생기가 구비되고; 상기 몸체 후방에는 상기 몸체 내부와 통하는 중공상의 등받이가 구비되고, 상기 등받이에는 이용자 위치마다 토출구가 형성되며; 각 상기 덕트의 출구는 상기 각 토출구와 일대일 대응되게 연결되어서 각 상기 온풍발생기의 온풍으로 인하여 좌판이 가열됨과 동시에 각 상기 출구를 따라 온풍이 이용자 쪽으로 향하도록 한 특징이 있다.To this end, in one embodiment of the present invention, a plurality of ducts are provided in a hollow body having a seat plate on which several people can sit apart for each seat where a user sits; Each of the ducts has an open upper surface and is directly exposed to the lower surface of the seat plate; A warm air generator having a PTC element is provided at the inlet of each of the ducts; A hollow backrest communicating with the inside of the body is provided at the rear of the body, and a discharge port is formed at each user position on the backrest; The outlet of each of the ducts is connected to each of the outlets in a one-to-one correspondence, so that the seat plate is heated by the warm air from each of the warm air generators and at the same time, the warm air is directed toward the user along each of the outlets.
본 발명에 따르면 벤치 내부에 앉는 자리마다 덕트가 설치되고, 각 상기 덕트 입구에는 PTC소자를 이용한 온풍발생기가 구비된다. 따라서 온풍발생기의 작동으로 인하여 각 앉는 자리는 예열되기 때문에 겨울철 좌판이 차갑지 않으므로 이용하는데 불편함을 느끼지 않는다. 또한 각 앉는 자리의 등받이 쪽에는 열풍이 이용자 쪽으로 향하는 토출구가 구비되며, 각 토출구는 해당 덕트와 연통된 상태에서 댐퍼로 여닫히게 구비된다.According to the present invention, a duct is installed at each seat inside the bench, and a warm air generator using a PTC element is provided at the entrance of each duct. Therefore, since each seat is preheated by the operation of the warm air generator, the seat is not cold in winter, so there is no inconvenience in using it. In addition, a discharge port for hot air directed toward the user is provided on the backrest side of each seat, and each discharge port is provided to be opened and closed by a damper while communicating with the corresponding duct.
따라서 이용자가 없을 때에는 상기 댐퍼가 닫히므로 토출구로 열풍이 빠져나가지 않으므로 열손실을 줄일 수 있으며, 특히 이용자가 해당 좌석에 앉으면 댐퍼가 열리면서 열기가 이용자 쪽으로 향하므로 체온을 빠르게 올릴 수 있으며 또한 여름철에는 상기 열풍발생기의 PTC소자를 작동시키지 않으면 찬 바람이 이용자 쪽으로 토출되므로 시원하게 이용할 수 있는 등의 이점이 있다.Therefore, since the damper is closed when there is no user, the hot air does not escape through the discharge port, so heat loss can be reduced. In particular, when the user sits on the seat, the damper opens and the heat is directed toward the user, so the body temperature can be raised quickly. If the PTC element of the hot air generator is not operated, cold wind is discharged toward the user, so there are advantages such as being able to use it coolly.

도 1 내지 도 5에서 본 발명 한 실시예의 벤치는 여러명이 앉을 수 있는 좌판(11)을 갖는 몸체(10)가 구비되고 상기 몸체(10) 양쪽 하부에는 다리(15)가 구비되며, 상기 몸체(10) 후방 상부에는 등받이(12)가 구비된다. 상기 몸체(10) 및 등받이(12)는 내부가 서로 통하는 중공상으로 형성되며, 상기 몸체(10) 내부에는 다수의 덕트(20)가 서로 떨어져 배치되는데, 각 덕트(20)는 이용자가 상기 좌판(11)에 앉는 직 하부 마다 놓인다. 또한 각 덕트(20)는 개방된 윗면이 상기 좌판(11) 밑면에 의해 막힌 상태가 되도록 각 덕트(20)는 좌판(11) 밑면에 결합되며, 각 덕트(20)의 입구는 온풍발생기(30)가 구비되고 출구는 상기 등받이(12) 내부와 연결된다. 그리고 상기 몸체(10) 전면에는 각 상기 온풍발생기(30)와 대응되는 흡입구(13)가 구비되고, 상기 등받이(12) 전면에는 각 상기 덕트(20)의 출구 연통되는 토출구(14)가 상기 좌판(11)의 앉는 자리마다 대응되게 구비된다.1 to 5, the bench of one embodiment of the present invention is provided with a body 10 having a seat 11 on which several people can sit, and legs 15 are provided on both lower portions of the body 10, and the body ( 10) The backrest 12 is provided at the rear upper part. The body 10 and the backrest 12 are formed in a hollow shape in which the insides communicate with each other, and a plurality of ducts 20 are disposed apart from each other inside the body 10, and each duct 20 is connected to the seat by the user. (11) is placed in each lower part of the seat. In addition, each duct 20 is coupled to the lower surface of the seat plate 11 so that the open upper surface is blocked by the lower surface of the seat plate 11, and the inlet of each duct 20 is connected to the warm air generator 30. ) is provided and the outlet is connected to the inside of the backrest 12. In addition, suction ports 13 corresponding to the warm air generators 30 are provided on the front surface of the body 10, and discharge ports 14 communicating with the outlets of the ducts 20 are provided on the front surface of the backrest 12. It is provided to correspond to each seat of (11).
상기 온풍발생기(30)는 팬모터(34)를 통하여 회전되는 팬(33)의 전방에 PTC소자(31)가 등간격으로 떨어져 배치되고, 각 PTC소자(31) 사이에는 지그재그 형태로 주름진 방열핀(32)이 구비된다. 따라서 온풍발생기(30)가 작동되면 PTC소자(31)의 열기가 방열핀(32)으로 전달되기 때문에 팬(33)에서 송풍되는 바람이 PTC소자(31)와 방열핀(32)을 거치면서 온풍으로 변한뒤 상기 덕트(20) 내부로 송풍된다.In the warm air generator 30, PTC elements 31 are spaced apart at equal intervals in front of the fan 33 rotated by the fan motor 34, and between the PTC elements 31, the radiation fins are wrinkled in a zigzag form ( 32) is provided. Therefore, when the warm air generator 30 is operated, heat from the PTC element 31 is transferred to the heat radiation fins 32, so that the wind blown from the fan 33 passes through the PTC element 31 and the heat radiation fins 32 to become warm air. Then, air is blown into the duct 20.
각 상기 덕트(20)의 출구에는 판상의 댐퍼(21)가 구비되어서 출구를 막고 있으므로 상기 온풍발생기(30)의 온풍은 덕트(20) 내부에 정체되므로 좌판(11)이 빠르게 가열된다. 또한 각 상기 댐퍼(21)는 하나의 회전축(22)을 통하여 연결되고 상기 회전축(22) 끝단은 제어모터(23)를 통하여 회전 제어된다. 따라서 상기 제어모터(23)의 작동으로 각 댐퍼(21)가 회전되어서 각 덕트(20)의 출구가 개방되면 각 덕트(20)에서 정체중인 온풍이 등받이(12)로 향한 뒤 각 토출구(14)를 거쳐서 이용자 쪽으로 토출된다.A plate-shaped damper 21 is provided at the outlet of each duct 20 to block the outlet, so that the warm air from the warm air generator 30 is stagnant inside the duct 20, so the seat plate 11 is quickly heated. In addition, each damper 21 is connected through one rotational shaft 22, and the rotation of the end of the rotational shaft 22 is controlled through a control motor 23. Therefore, when each damper 21 is rotated by the operation of the control motor 23 and the outlet of each duct 20 is opened, the warm air stagnant in each duct 20 is directed to the backrest 12 and then discharged through each outlet 14 It passes through and is discharged toward the user.
이처럼 구성된 본 발명 한 실시예의 벤치는 평상시 이용자가 없을 때에는 각 덕트(20)의 댐퍼(21)가 닫힌 상태로 유지되므로 온풍발생기(30)의 열기가 덕트(20) 내부에 정체되어서 좌판(11)을 빠르게 가열시키므로 겨울철 좌판(11)이 차갑게 되지 않으므로 이용하는데 지장을 주지 않는다. 그리고 이용자가 좌판(11)에 앉으면 이를 근접센서(미도시)가 감지하여서 상기 제어모터(23)를 작동시키므로 각 댐퍼(21)는 동시에 회전되어서 각 상기 덕트(20)의 출구가 개방되므로 열기가 상기 등받이(12)의 토출구(14)를 따라 이용자 쪽으로 향한다.In the bench of one embodiment of the present invention configured as described above, since the damper 21 of each duct 20 is maintained in a closed state when there is no user in normal times, the heat of the warm air generator 30 is stagnant inside the duct 20 and the seat 11 Since the seat plate 11 does not become cold in winter because it heats up quickly, it does not interfere with use. In addition, when a user sits on the seat 11, a proximity sensor (not shown) detects this and operates the control motor 23, so that each damper 21 is rotated at the same time and the outlet of each duct 20 is opened, so heat is generated. It goes toward the user along the discharge port 14 of the backrest 12.
이러한 본 발명 한 실시예는 몸체(10) 내부에 다수의 덕트(20)가 등간격으로 떨어져 배치되는데, 이들 덕트(20)는 이용자가 좌판(11)에 앉는 위치마다 구비된다. 그리고 각 덕트(20) 입구는 온풍발생기(30)가 구비되어서 온풍이 각 덕트(20)로 공급되면 이용자가 앉는 좌석만 집중적으로 가열시키기 때문에 좌판(11) 전체를 온풍으로 가열시킬 때 보다 열효율이 향상되는 이점이 있다. 또한 상기 좌판(11)이 일정온도에 도달되면 각 상기 온풍발생기(30) 운전을 제어하여 온/오프시킬 수 도 있다.In this embodiment of the present invention, a plurality of ducts 20 are arranged at regular intervals inside the body 10, and these ducts 20 are provided at each position where the user sits on the seat 11. In addition, since the warm air generator 30 is provided at the inlet of each duct 20, when the warm air is supplied to each duct 20, only the seat where the user sits is intensively heated, so the heat efficiency is higher than when the entire seat 11 is heated with warm air. There are benefits to improving. In addition, when the seat plate 11 reaches a certain temperature, the operation of each warm air generator 30 may be controlled to turn on/off.
또한 좌판(11)에는 상기 등받이(12)에 형성된 토출구(14)와 대응되게 좌석표시(미도시)가 인쇄될 수 있으며, 이러한 좌석표시에 이용자가 앉으면 근접센서(미도시)가 이를 감지하여 댐퍼(21)가 열리도록 상기 제어모터(23)를 동작시킨다. 따라서 각 상기 댐퍼(21)는 등받이(12) 내부의 각 토출구(14)와 일대일로 통하게 되므로 온풍이 이용자의 등 쪽으로 집중 토출되기 때문에 체온을 빠르게 올릴 수 있는 등의 이점이 있다.In addition, a seat mark (not shown) may be printed on the seat plate 11 to correspond to the discharge port 14 formed on the backrest 12, and when a user sits on such a seat mark, a proximity sensor (not shown) detects it, and the damper The control motor (23) is operated so that (21) is opened. Accordingly, since each of the dampers 21 communicates with each outlet 14 inside the backrest 12 one-to-one, warm air is discharged intensively toward the back of the user, so that the body temperature can be raised quickly.
