Description

히트펌프식 건조기{A drying apparatus using a heat pump}Heat pump dryer {A drying apparatus using a heat pump}

본 발명은 히트펌프식 건조기에 관한 것으로써, 특히, 증발기에 의해 냉각된 공기를 상기 증발기에 공급하는 순환덕트를 포함하는 히트펌프식 건조기에 관한 것이다.The present invention relates to a heat pump dryer, and more particularly, to a heat pump dryer including a circulation duct for supplying air cooled by an evaporator to the evaporator.

종래, 히트 펌프 유닛을 구비한 세탁 건조기로서는 예를 들어 한국공개특허 2007-0081440호에 기재된 것이 있다. 상기 히트 펌프 유닛은 압축기, 증발기 및 응축기를 일체화하여 구성되어 있다. 그리고 상기 응축기에서 가열된 공기를 수조의 급기구로 공급하고, 수조내의 드럼을 통과하여 수조의 배기구로부터 토출시켜 상기 증발기에 의해 냉각 제습하고, 다시 상기 응축기에서 가열하는 것을 반복하여 건조를 실시하고 있다.Conventionally, as a laundry dryer provided with a heat pump unit, there exist some which were described in Unexamined-Japanese-Patent No. 2007-0081440, for example. The heat pump unit is configured by integrating a compressor, an evaporator and a condenser. Then, the air heated in the condenser is supplied to the air supply port of the tank, discharged from the exhaust port of the tank through the drum in the tank, cooled and dehumidified by the evaporator, and repeatedly heated in the condenser. .

이러한 종래의 히트펌프식 건조기에서는 부하변동에 대응하기 위해 아래와 같은 방법을 사용했다.In the conventional heat pump type dryer, the following method was used to cope with load fluctuations.

증발기 쪽으로 유입되는 공기온도를 제어하기 위해서 외부공기와 열교환하는 배열기를 설치한 구조를 채택하거나, 일부 공기를 외부로 배출하고 배출한 공기유량만큼의 외부 신선공기를 흡입하는 구조를 채택하고 있다.In order to control the temperature of the air flowing into the evaporator, it adopts a structure in which a heat exchanger is installed to exchange heat with external air, or a structure in which some air is discharged to the outside and the external fresh air is sucked in as much as the discharged air flow.

그러나, 이러한 종래의 방법으로는 외기가 고온 다습일때는 문제를 부하변동에 대응할 수 없는 문제점이 있다. 건조가 불가능하거나 인버터압축기의 능력을 최대로 증가시키면서 부하변동에 대비하고 있으나, 일정 온도까지 외기온도가 상승하거나 습도가 높아지면 반복적인 압축기 단속운전이 필요하게 된다. 이렇게 되면 건조기 본연의 의류 건조기능을 제공하지 못하는 문제점이 있다.However, such a conventional method has a problem that the problem cannot cope with load fluctuations when the outside air is high temperature and high humidity. Although it is impossible to dry or increase the capacity of the inverter compressor to the maximum, it is preparing for load fluctuations, but if the outside temperature rises to a certain temperature or the humidity becomes high, repeated compressor intermittent operation is required. If this happens, there is a problem in that it does not provide a dryer drying function.

본 발명은 전술한 문제를 해결하기 위하여 안출된 것으로, 외기의 온도가 상승하거나 습도가 높아지는 것과 같이 부하에 변동이 생기더라도 건조기가 원활하게 운전가능해지는 히트펌프식 건조기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a heat pump type dryer that can be operated smoothly even if the load fluctuates, such as an increase in temperature of the outside air or an increase in humidity.

전술한 목적을 달성하기 위한 본 발명의 히트펌프식 건조기는, 덕트와, 상기 덕트 내부의 공기를 순환시키는 송풍팬과, 상기 덕트의 공기를 가열하는 응축기와, 상기 응축기에 연결되는 팽창밸브와, 상기 덕트의 공기를 냉각시키고 상기 팽창밸브에 연결되는 증발기와, 상기 증발기와 상기 응축기에 연결되는 압축기와, 상기 증발기에 의해 냉각된 공기를 상기 증발기에 공급하는 순환덕트를 포함한다.The heat pump type dryer of the present invention for achieving the above object, a duct, a blowing fan for circulating air in the duct, a condenser for heating the air of the duct, an expansion valve connected to the condenser, And an evaporator connected to the expansion valve to cool the air in the duct, a compressor connected to the evaporator and the condenser, and a circulation duct for supplying air cooled by the evaporator to the evaporator.

상기 순환덕트로 공기를 순환시키는 순환팬을 더 포함하고, 상기 순환덕트에는 풍량조절댐퍼가 설치되며, 상기 증발기는 제1증발기와 제2증발기를 포함하며, 상기 순환덕트는 상기 제2증발기에 의해 냉각된 공기를 상기 제1증발기에 공급할 수 있다.The circulation duct further includes a circulation fan for circulating air through the circulation duct, and the air flow control damper is installed in the circulation duct, the evaporator includes a first evaporator and a second evaporator, and the circulation duct is provided by the second evaporator. Cooled air may be supplied to the first evaporator.

이상에서 설명한 바와 같은 본 발명의 히트펌프식 건조기에 따르면, 다음과 같은 효과가 있다.According to the heat pump type dryer of the present invention as described above, there are the following effects.

증발기에 의해 냉각된 공기를 상기 증발기에 공급하는 순환덕트를 포함하여, 부하에 변동이 생기더라도 고온다습의 외기에 관계없이 부하 변동에 대응할 수 있 게 되어 건조기가 원활하게 운전가능해진다.Including a circulation duct for supplying the air cooled by the evaporator to the evaporator, even if the load fluctuates, it is possible to cope with the load fluctuation regardless of the outside air of the high temperature and high humidity, thereby enabling the dryer to operate smoothly.

상기 순환덕트로 공기를 순환시키는 순환팬을 더 포함하여, 순환이 더욱 원활하게 될 수 있다.Further comprising a circulation fan for circulating the air to the circulation duct, it is possible to more smoothly circulate.

상기 순환덕트에는 풍량조절댐퍼가 설치되어, 부하 변동크기에 따라 순환되는 공기의 양을 조절할 수 있게 되어 건조기의 운전이 더욱 원활해진다.The circulation duct is provided with a wind volume control damper, it is possible to adjust the amount of air circulated according to the load fluctuation size, the operation of the dryer is more smooth.

덕트(100)는 내부 공기가 순환되도록 형성된다.Duct 100 is formed to circulate the internal air.

덕트(100)에는 의류와 같은 건조대상물이 건조되는 건조실(110)이 형성된다.In the duct 100, a drying chamber 110 in which a drying object such as clothing is dried is formed.

송풍팬(200)는 덕트(100) 내부에 배치되어 덕트(100) 내부의 공기를 순환시킨다.The blowing fan 200 is disposed in the duct 100 to circulate air in the duct 100.

응축기(400)는 건조실(110)보다 상류에 배치되도록 덕트(100) 내부에 배치되어 덕트(100)의 공기를 가열한다.The condenser 400 is disposed inside the duct 100 to be disposed upstream of the drying chamber 110 to heat the air in the duct 100.

팽창밸브(500)는 응축기(400)에 연결된다.Expansion valve 500 is connected to the condenser 400.

증발기(300)는 덕트(100)의 공기를 냉각시키고 상기 팽창밸브(500)에 연결된다.The evaporator 300 cools the air in the duct 100 and is connected to the expansion valve 500.

이러한 증발기(300)는 응축기(400)보다 상류에 배치되도록 덕트(100) 내부에 배치된다.The evaporator 300 is disposed inside the duct 100 to be disposed upstream of the condenser 400.

압축기(600)는 증발기(300)와 응축기(400)에 연결된다.The compressor 600 is connected to the evaporator 300 and the condenser 400.

순환덕트(700)는 증발기(300)에 의해 냉각된 공기를 증발기(300)에 공급한다.The circulation duct 700 supplies the air cooled by the evaporator 300 to the evaporator 300.

순환팬(710)은 순환덕트(700) 내부에 배치되어 순환덕트(700)로 공기를 순환시킨다.The circulation fan 710 is disposed inside the circulation duct 700 to circulate air to the circulation duct 700.

상세하게는, 순환팬(710)은 증발기(300)에 의해 냉각된 공기를 강제적으로 순환덕트(700)로 유입되도록 하여 냉각된 공기가 증발기(300)에 다시 공급되도록 한다.In detail, the circulation fan 710 forces the air cooled by the evaporator 300 to flow into the circulation duct 700 so that the cooled air is supplied to the evaporator 300 again.

또한, 순환덕트(700)에는 풍량조절댐퍼(720)가 설치된다.In addition, the air flow control damper 720 is installed in the circulation duct 700.

이러한 경우에는 순환덕트(700)는 제1증발기(300a) 상류와 제2증발기(300b)와 응축기(400) 사이를 연결하도록 덕트(100)에 연통되도록 설치된다.In this case, the circulation duct 700 is installed to communicate with the duct 100 so as to be connected upstream of the first evaporator 300a and between the second evaporator 300b and the condenser 400.

이러한 순환덕트(700)는 제2증발기(300b)에 의해 냉각된 공기를 상기 제1증발기(300a)에 공급한다.The circulation duct 700 supplies the air cooled by the second evaporator 300b to the first evaporator 300a.

이하, 전술한 구성을 갖는 본 실시예의 작용을 설명한다.The operation of this embodiment having the above-described configuration will be described below.

압축기(600)에서 압축된 고온고압의 냉매가스는 냉매관을 통해 응축기(400)로 이동하여 상기 냉매가스의 열을 방열하면서 액화된다.The refrigerant gas of the high temperature and high pressure compressed by the compressor 600 is liquefied while moving to the condenser 400 through the refrigerant pipe to dissipate heat of the refrigerant gas.

응축기(400)를 통과한 냉매는 팽창밸브(500)를 거치면서 저온, 저압으로 변화된다.The refrigerant passing through the condenser 400 is changed to low temperature and low pressure while passing through the expansion valve 500.

팽창밸브(500)를 통과하여 감압된 냉매는 증발기(300)로 이동한다.The refrigerant decompressed through the expansion valve 500 moves to the evaporator 300.

증발기(300)를 통과한 저온저압의 냉매는 다시 압축기(420)로 이동한다.The low temperature low pressure refrigerant passing through the evaporator 300 is moved to the compressor 420 again.

증발기(300)에 의해 덕트(100)의 공기는 냉각되는 동시에 건조된다.The air in the duct 100 is cooled and dried by the evaporator 300.

응축기(400)에서 방열된 열에 의해 덕트(100)의 공기는 고온 건조 상태로 건조실(110)로 송풍팬(200)에 의해 이동된다.Air of the duct 100 is moved by the blower fan 200 to the drying chamber 110 in a high temperature dry state by the heat radiated from the condenser 400.

고온 건조한 공기는 건조실(110)에서 건조대상물(미도시)을 건조시키고 습기를 흡수한다.The high temperature dry air dries the object to be dried (not shown) in the drying chamber 110 and absorbs moisture.

고온 다습해진 공기는 증발기(300) 쪽으로 이동되어 냉각된다. The hot and humid air is moved toward the evaporator 300 and cooled.

공기는 증발기(300)에 의해 냉각되어 온도가 낮아지는 동시에, 공기 내부의 수분이 증발기(300) 표면에 응결된다. 따라서, 공기는 저온 저습 상태로 된다.The air is cooled by the evaporator 300 to lower the temperature and at the same time moisture inside the air condenses on the surface of the evaporator 300. Therefore, the air is brought to a low temperature and low humidity state.

이러한 응결수는 증발기(300)에 설치된 배출구(미도시)를 통해 외부로 배출된다.Such condensed water is discharged to the outside through an outlet (not shown) installed in the evaporator (300).

한편, 증발기(300)를 통과한 공기의 일부는 응축기(400) 쪽으로 이동되고, 일부는 순환덕트(700) 쪽으로 이동된다.On the other hand, a part of the air passing through the evaporator 300 is moved toward the condenser 400, a part is moved toward the circulation duct 700.

순환덕트(700)로 유입된 공기는 다시 증발기(300)에 공급된다.The air introduced into the circulation duct 700 is supplied to the evaporator 300 again.

이로 인해 공기는 이차적으로 증발기(300)에 의해 냉각되고 습기도 흡수된다. 따라서, 부하가 변동될 경우에도 외기온도 및 습도와 무관하게 건조대상물이 원활하고 안정적으로 건조된다.As a result, the air is secondarily cooled by the evaporator 300 and moisture is also absorbed. Therefore, even when the load is changed, the object to be dried is dried smoothly and stably regardless of the outdoor temperature and humidity.

나아가, 제어부를 통해 부하가 클 경우에는 풍량조절댐퍼(720)를 조절하여 순환덕트(700)를 통과하는 유량이 많도록 하고, 부하가 작을 경우에는 풍량조절댐퍼(720)를 조절하여 순환덕트(700)를 통과하는 유량이 작아지도록 할 수 있다.Furthermore, when the load is large through the control unit, the flow rate control damper 720 is adjusted to increase the flow rate through the circulation duct 700, and when the load is small, the flow rate control damper 720 is adjusted to adjust the circulation duct ( The flow rate passing through 700 may be reduced.
