Abstract

Disclosed is a clothes dryer which includes a chamber unit; a heat exchange unit which is arranged at the lower part of the chamber unit and has a circulation structure where a refrigerant discharged from a compressor is transferred to an evaporator via a liquid phase refrigerant transfer pipe and then the refrigerant is returned to the compressor via a gas phase refrigerant transfer pipe; and a drying unit where clothes can hang inside an inner chamber. In the disclosed invention, the chamber unit comprises the inner chamber accommodating the clothes; an outer chamber which is arranged to surround the inner chamber and is spaced from the inner chamber; an air transfer unit which transfers air through a gap between the inner chamber and the outer chamber; and a door which is arranged at the same side of the inner chamber and the outer chamber. The evaporator of the heat exchange unit is a laminated evaporator consisting of a plurality of layers which are arranged in a zigzag form and are connected with each other. The disclosed clothes dryer can exhibit maximum drying efficiency in a short time at low power by utilizing a difference in density of the saturated vapor which depends on the temperature of the vapor. In addition, the clothes dryer prevents shrinking of clothes during the drying process through low temperature drying. Moreover, since the rubbing of clothes is inhibited, the clothes dryer can prevent surface damages caused by friction. Also, the noise of the dryer can be minimized.

표 1을 보면 공기의 온도가 5℃일때 포화증기밀도는 6.88g/m3이고, 5℃ 보다 온도가 저하되어도 증기밀도가 급격하게 감소되지는 않음을 알 수 있다. 공기의 온도가 5℃보다 증가하면 포화증기밀도도 증가하게 되는데, 약 10℃에 도달할 때까지는 포화증기밀도의 증가율이 완만한데, 10℃를 초과하면 포화증기밀도의 증가율이 급격하게 증가하게 된다.Table 1 shows that the saturated steam density is 6.88 g / m 3 when the air temperature is 5 ° C., and the vapor density does not rapidly decrease even when the temperature is lower than 5 ° C. When the temperature of the air increases above 5 ° C, the saturated steam density also increases. Until the temperature reaches about 10 ° C, the saturated steam density increases slowly. When it exceeds 10 ° C, the saturated steam density increases rapidly. .
표 1을 보면 공기의 온도가 40℃일때 포화증기밀도는 51.04g/m3이고, 공기의 온도가 45℃일때 포화증기밀도는 64.61g/m3이고, 공기의 온도가 50℃일때 포화증기밀도는 80.69g/m3임을 알 수 있다.In the Table 1, the temperature of the air 40 ℃ when the saturated vapor density of 51.04g / m 3, and the temperature of the air 45 ℃ when the saturated vapor density of 64.61g / m 3, and the saturated vapor concentration when the temperature of the air 50 ℃ It can be seen that is 80.69g / m 3 .
표 1을 보면 온도가 45℃이고 습도가 약 95%인 공기에는 약 64.61g/m3의 수증기가 함유되어 있는데, 이 공기의 온도를 5℃로 저하시키면 해당 온도에서 공기가 함유할 수 있는 포화수증기량은 6.88g/m3이므로 차이에 해당되는 약 57.73g의 수증기가 응축되어 배출된다.In the Table 1, the temperature is 45 ℃ and saturated with humidity there is an air of about 95% is contained in about 64.61g / m 3 of water vapor, when lowering the temperature of the air to 5 ℃ may contain air at the temperature Since the amount of water vapor is 6.88 g / m 3 , approximately 57.73 g of water vapor corresponding to the difference is condensed and discharged.
이러한 원리를 이용하면 내부챔버(110)의 내부온도를 매우 높은 고온으로 하지 않아도 건조대상물을 최적으로 건조시킬 수 있게 된다.By using this principle, it is possible to optimally dry the object to be dried even if the internal temperature of the internal chamber 110 is not set to a very high temperature.
한편, 공기의 온도를 일정 정도 감소시키기 위하여는 냉매의 선택 등 여러 측면에서 고비용 등의 문제점이 있다. 따라서 본 발명에 따른 의류건조기는 적층식 증발기(230)를 통과한 직후의 저온건조한 공기의 온도를 1℃ ~ 10℃ 의 범위로 유지하는 것이 바람직하다. 나아가 공기 냉각의 에너지 효율성까지 고려하면 4℃ ~ 6℃의 범위가 보다 바람직하다.On the other hand, in order to reduce the temperature of the air to some extent there are problems such as high cost in various aspects such as the selection of the refrigerant. Therefore, the clothes dryer according to the present invention preferably maintains the temperature of the low temperature dry air immediately after passing through the stacked evaporator 230 in the range of 1 ° C to 10 ° C. Furthermore, considering the energy efficiency of air cooling, the range of 4 ° C to 6 ° C is more preferable.
그리고 의류건조기에는 다양한 소재의 의류가 건조되어야 할 것이다. 따라서, 열변형이 용이한 소재로된 의류의 건조를 고려하면, 본 발명에 따른 내부챔버(110)의 내부온도는 40℃ ~ 50℃의 범위로 유지되는 것이 바람직하다. 나아가 공기 가열의 에너지 효율성까지 고려하면 44℃ ~ 46℃의 범위로 유지되는 것이 바람직하다. And the clothes dryer will have to dry clothes of various materials. Therefore, considering the drying of the clothing made of a material that is easy to heat deformation, the internal temperature of the inner chamber 110 according to the present invention is preferably maintained in the range of 40 ℃ ~ 50 ℃. Furthermore, considering the energy efficiency of air heating is preferably maintained in the range of 44 ℃ ~ 46 ℃.
만약 내부챔버(110)의 기 설정된 내부온도의 범위에 미달되면, 순간가열부(260)를 작동시켜 내부온도를 상승시킬 수 있고, 만약 기 설정된 내부온도의 범위를 초과하면 외기흡입부(270)를 개방하여 내부온도를 저하시킬 수 있다.If the internal chamber 110 is lower than the preset internal temperature range, the instantaneous heating unit 260 may be operated to increase the internal temperature. If the internal temperature exceeds the preset internal temperature range, the external air suction unit 270 may operate. The internal temperature can be lowered by opening.
이러한 실시예를 통해 알 수 있듯이, 본 발명에 따른 의류건조기는, 기존의 고열을 이용한 의류건조기보다 상대적으로 낮은 온도를 이용하므로 에너지절약형일뿐 아니라 의류의 수축 등 변형이 방지될 수 있다. 또한 드럼회전방식이 아니므로 소음발생이 최소화될 뿐만 아니라, 의류의 충돌로 인한 표면 손상 등이 방지될 수 있다.As can be seen through this embodiment, the clothes dryer according to the present invention, because it uses a relatively lower temperature than the conventional clothes dryer using a high temperature, not only energy-saving but also can be prevented deformation such as shrinkage of the clothes. In addition, since the drum is not rotated, noise is minimized, and surface damage due to a collision of clothes can be prevented.
본 발명에 따른 건조기는 의류를 건조하는 데 일차적으로 사용될 수 있으나, 본 발명의 기술적 원리를 이용하여 다른 건조대상물을 건조할 수도 있을 것이며, 이 경우에도 본 발명의 기술적 사상에 포함된다.The dryer according to the present invention may be used primarily to dry clothes, but may dry other objects to be dried using the technical principles of the present invention, which is also included in the technical idea of the present invention.
본 실시예 및 본 명세서에 첨부된 도면은 본 발명에 포함되는 기술적 사상의 일부를 명확하게 나타내고 있는 것에 불과하며, 본 발명의 명세서 및 도면에 포함된 기술적 사상의 범위 내에서 당업자가 용이하게 유추할 수 있는 변형 예와 구체적인 실시예는 모두 본 발명의 권리범위에 포함되는 것은 자명하다.The embodiments and drawings attached to this specification are merely to clearly show some of the technical ideas included in the present invention, and those skilled in the art can easily infer within the scope of the technical ideas included in the specification and drawings of the present invention. It is apparent that all modifications and specific embodiments that can be included in the scope of the present invention.
