Dishwasher 10 according to the present embodiment is disposed on one side of the tub 14, the air discharged from the tub 14 through the circulation duct inlet (60b) (hereinafter 'first air (A1)') The first air duct 60 that flows, the outside air inflow duct 62 through which the air introduced from the outside (hereinafter referred to as 'second air A2') flows, and the first air that flows through the first circulation duct 60 The fan assembly 68 for introducing and discharging the second air A2 flowing through the A1 and the outside air inlet duct 62 and the air discharged from the fan assembly 68 are heated and supplied to the tub 14. The second circulation duct 64 includes an exhaust duct 66 for exhausting the air discharged from the fan assembly to the outside of the cabinet 12. Here, the air flowing in the second circulation duct 64 is divided into the third air A3 and the air flowing in the exhaust duct 66 is described as the fourth air A4.
제1순환덕트(60)는 순환덕트유입홀(60b)을 통해 터브(14) 내부의 세척실(14a)에서 배출된 공기가 유입된다. 또한, 제1순환덕트(60)를 유동하는 공기는 팬어셈블리(68)로 유동한다. 제1순환덕트(60)의 내부에는 터브(14)에서 배출된 공기가 유동하는 제1순환유로(60a)가 형성된다. 본 실시예에 따른 제1순환덕트(60)는 일측에서 외기유입덕트(62)가 연결될 수 있다. In the first circulation duct 60, the air discharged from the washing chamber 14a inside the tub 14 is introduced through the circulation duct inlet hole 60b. In addition, the air flowing through the first circulation duct 60 flows to the fan assembly 68. A first circulation passage 60a through which air discharged from the tub 14 flows is formed in the first circulation duct 60. The first circulation duct 60 according to the present embodiment may be connected to the external air inlet duct 62 at one side.
외기유입덕트(62)는 캐비닛(12) 외부에서 유입된 외부공기가 유동하는 외기유로(62a)를 형성한다. 외기유입덕트(62)는 캐비닛(12)의 후방이나 하측으로 외부와 연통될 수 있다. 또한, 캐비닛(12)과 터브(14)의 하측에 형성되는 공간으로 연통되는 것도 가능하다. 외기유로(62a)를 유동하는 제2공기(A2)는 제1공기(A1)와 혼합되어, 터브(14)에서 배출된 순환공기의 습도를 낮춘다.The outside air inlet duct 62 forms an outside air flow path 62a through which external air introduced from the outside of the cabinet 12 flows. The outside air inlet duct 62 may communicate with the outside at the rear or the bottom of the cabinet 12. It is also possible to communicate with a space formed under the cabinet 12 and the tub 14. The second air A2 flowing through the outside air passage 62a is mixed with the first air A1 to lower the humidity of the circulating air discharged from the tub 14.
제1순환덕트(60)의 유로단면적과 외기유입덕트(62)의 유로단면적의 크기는 상이하게 형성될 수 있다. 따라서, 제1순환유로(60a)의 단면적과, 외기유로(62a)의 단면적의 크기를 조절하여, 팬어셈블리(68)로 유입되는 외기의 혼합비율을 조절할 수 있다. The passage cross-sectional area of the first circulation duct 60 and the passage cross-sectional area of the external air inlet duct 62 may be formed differently. Therefore, by adjusting the size of the cross-sectional area of the first circulation passage (60a) and the cross-sectional area of the external air passage (62a), it is possible to adjust the mixing ratio of the outside air flowing into the fan assembly (68).
제2순환덕트(64)는 터브(14)에서 배출된 제1공기(A1)가 외부에서 유입된 제2공기와 혼합된 공기가 유동하는 제2순환유로(64a)를 형성한다. 따라서, 제2순환덕트(64)를 유동하는 제3공기(A3)는 제1공기(A1)에 비해 습도가 낮아진 상태를 유지할 수 있다. 제2순환덕트(64)에서는 제2순환유로(64a)를 유동하는 공기를 가열하는 순환부히터(70)가 배치된다. 순환부히터(70)는 제2순환덕트(64)의 입구단에 배치된다. 순환부히터(70)는 이하에서 설명할 제2조절밸브(74)의 하류에 배치된다. The second circulation duct 64 forms a second circulation passage 64a through which air mixed with the second air introduced from the outside of the first air A1 discharged from the tub 14 flows. Therefore, the third air A3 flowing through the second circulation duct 64 may maintain a state in which the humidity is lower than that of the first air A1. In the second circulation duct 64, a circulation unit heater 70 for heating air flowing through the second circulation channel 64a is disposed. The circulation heater 70 is disposed at the inlet end of the second circulation duct 64. The circulation heater 70 is disposed downstream of the second control valve 74 to be described below.
제2순환덕트(64)를 유동하는 제3공기(A3)만이 가열될 수 있다. 제2순환덕트(64)를 유동하는 제3공기(A3)는 순환부히터(70)에 의해 가열되어 터브(14) 내부의 세척실(14a)로 공급된다. Only the third air A3 flowing through the second circulation duct 64 may be heated. The third air A3 flowing through the second circulation duct 64 is heated by the circulation heater 70 and supplied to the washing chamber 14a inside the tub 14.
배기덕트(66)는 터브(14)에서 배출된 제1공기(A1)가 외부에서 유입된 제2공기와 혼합된 공기가 유동하는 배기유로(66a)를 형성한다. 따라서, 배기유로(66a)를 유동하는 제4공기(A4)는 제1공기(A1)에 비해 습도가 낮아진 상태로 배기될 수 있다. 따라서, 캐비닛(12) 외부로 터브(14)에서 배출된 습한 공기가 직접 배출되지 않는다. The exhaust duct 66 forms an exhaust passage 66a through which air mixed with the second air introduced from the outside of the first air A1 discharged from the tub 14 flows. Therefore, the fourth air A4 flowing through the exhaust passage 66a may be exhausted in a state where the humidity is lower than that of the first air A1. Therefore, the humid air discharged from the tub 14 to the outside of the cabinet 12 is not directly discharged.
제2순환덕트(64)의 유로단면적과 배기덕트(66)의 유로단면적의 크기는 상이하게 형성될 수 있다. 따라서, 제2순환유로(64a)의 단면적과, 배기유로(66a)의 단면적의 크기를 조절하여, 터브(14)에서 배출된 공기를 순환하는 공기의 유량과 배기되는 공기의 유량을 조절할 수 있다. The flow path cross-sectional area of the second circulation duct 64 and the flow path cross-sectional area of the exhaust duct 66 may be formed differently. Therefore, by adjusting the size of the cross-sectional area of the second circulation passage 64a and the cross-sectional area of the exhaust passage 66a, the flow rate of air circulating the air discharged from the tub 14 and the flow rate of the exhausted air can be adjusted. .
본 실시예에 따른 배기덕트(66)는 터브(14)의 상측 전방으로 배기구(67a, 67b)를 형성할 수 있다. 본 실시예에 따른 배기구(67a, 67b)는 터브(14)의 전방 상측에서 복수개가 형성될 수 있다. 본 실시예에 따른 배기구(67a, 67b)는 도어(16)의 잠금상태를 고려하여, 도어(16)의 구성에 간섭되지 않는 영역으로 배치될 수 있다.The exhaust duct 66 according to the present exemplary embodiment may form the exhaust ports 67a and 67b in the upper front of the tub 14. A plurality of exhaust ports 67a and 67b according to the present embodiment may be formed at the front upper side of the tub 14. The exhaust ports 67a and 67b according to the present exemplary embodiment may be disposed in an area that does not interfere with the configuration of the door 16 in consideration of the locked state of the door 16.
팬어셈블리(68)는 외형을 형성하며, 제1혼합덕트(76)와 제2혼합덕트(78)를 연결하는 팬하우징(미도시), 팬하우징 내부에 배치되어, 공기의 유동을 형성하는 팬(미도시), 팬을 구동시키는 팬모터(미도시)를 포함할 수 있다.The fan assembly 68 forms an outer shape, a fan housing (not shown) connecting the first mixing duct 76 and the second mixing duct 78 and a fan disposed inside the fan housing to form a flow of air.

팬하우징으로 유입된 제1공기(A1)와 제2공기(A2)는 팬하우징 내부에서 회전하는 팬에 의해, 팬하우징 내부를 유동하며, 더욱 혼합될 수 있다. 본 실시예에 따른 팬하우징에는 제1혼합덕트(76)와 연통하는 유입구(미도시)와, 제2혼합덕트(78)와 연통하는 배출구(미도시)가 각각 하나씩 형성될 수 있다. The first air A1 and the second air A2 introduced into the fan housing may flow through the inside of the fan housing by a fan rotating inside the fan housing, and may be further mixed. In the fan housing according to the present exemplary embodiment, one inlet port (not shown) communicating with the first mixing duct 76 and one outlet port (not shown) communicating with the second mixing duct 78 may be formed.
본 실시예에 따른 식기세척기(10)는 제1순환덕트(60)와 외기유입덕트(62)에서 유입되는 공기를 혼합하여 팬어셈블리(68)로 공급하는 제1혼합덕트(76)와, 팬어셈블리(68)에서 배출된 공기를 제2순환덕트(64)와 배기덕트(66) 각각으로 공급하는 제2혼합덕트(78)를 포함한다. The dishwasher 10 according to the present exemplary embodiment includes a first mixing duct 76 and a fan that mix air supplied from the first circulation duct 60 and the air inlet duct 62 and supply the same to the fan assembly 68. And a second mixing duct 78 for supplying the air discharged from the assembly 68 to each of the second circulation duct 64 and the exhaust duct 66.
