Description

오븐Oven
본 발명은 도어 외부의 표면 온도를 낮추면서 에너지 효율을 개선할 수 있는 쿨링 구조를 갖는 오븐에 관한 것이다.The present invention relates to an oven having a cooling structure capable of improving energy efficiency while lowering a surface temperature outside a door.
일반적으로 오븐은 조리실과, 조리실에 열을 가하는 가열장치와, 가열장치에서 발생된 열을 조리실 내부에서 순환시키는 순환 팬을 구비하여 음식을 조리하는 기기이다.In general, an oven is a device that cooks food by having a cooking chamber, a heating device that applies heat to the cooking chamber, and a circulation fan that circulates heat generated by the heating device in the cooking chamber.
오븐은 조리물을 밀폐, 가열하여 조리하는 기구로서 일반적으로 그 열원에 따라 전기식, 가스식, 전자식으로 구분할 수 있다.Ovens are devices for cooking by sealing and heating food. In general, ovens can be classified into electric, gas, and electronic types according to their heat sources.
전기오븐은 전기히터를 열원으로 이용하고, 가스오븐과 전자레인지는 각각 가스에 의한 열과 고주파로 인한 물분자의 마찰열을 열원으로 이용한다.Electric ovens use an electric heater as a heat source, and gas ovens and microwave ovens use heat from gas and frictional heat from water molecules due to high frequency as heat sources, respectively.
일반적으로 오븐은 외관을 이루며 전면이 개방되어 내부에 조리될 음식물이 투입되는 조리실이 형성된 본체와, 본체의 전면에 설치되어 조리실을 선택적으로 개폐하는 도어를 포함한다.In general, an oven includes a main body that forms an exterior and has a cooking chamber in which food to be cooked is input, and a door installed in the front of the main body to selectively open and close the cooking chamber.
도어는 조리실 내부의 열이 외부로 방출되는 것을 방지하기 위해 복수의 글래스로 구성된다. 도어는 조리실 내부의 열에 의해 온도가 상승하기 때문에, 도어의 온도 상승을 방지하기 위해 도어에는 외부의 공기가 흡입되는 공기 흡입구가 마련되며, 공기 흡입구로 흡입된 공기는 복수의 글래스 사이사이에 마련되는 공기유로를 순환하여 공기의 온도를 낮춘 후 도어 외부로 배출된다.The door is composed of a plurality of glasses to prevent heat inside the cooking compartment from being radiated to the outside. Since the temperature of the door rises due to heat inside the cooking compartment, the door is provided with an air intake port through which outside air is sucked in to prevent the temperature of the door from rising, and the air sucked through the air inlet is provided between a plurality of glasses. It is discharged to the outside of the door after reducing the temperature of the air by circulating the air flow path.
일반적으로, 도어 외부의 표면 온도를 낮추기 위해서 벤츄리 효과를 이용한 쿨링 구조에 의해 도어 내부의 고온의 공기를 도어 외부로 배출시키거나, 냉각팬에 의해 강제로 도어 내부의 고온의 공기를 흡입하여 도어 외부로 배출시킨다.In general, in order to lower the surface temperature of the door, the hot air inside the door is discharged to the outside of the door by a cooling structure using a venturi effect, or the hot air inside the door is forcibly sucked by a cooling fan to the outside of the door.

There is a problem that it is difficult to lower the surface temperature.
또한, 냉각팬에 의해 강제로 도어 내부의 고온의 공기를 흡입하여 도어 외부로 배출시키는 경우 일관된 성능 확보가 가능하고 도어 외부의 표면 온도를 낮게 유지할 수 있지만, 상대적으로 높은 재료비가 필요하다.In addition, when hot air inside the door is forcibly inhaled by the cooling fan and discharged to the outside of the door, consistent performance can be secured and the surface temperature outside the door can be kept low, but a relatively high material cost is required.
특히, 오븐은 일반 조리 모드의 경우보다 청소 모드의 경우 조리실 내부 온도가 크게 상승하기 때문에, 청소 모드의 경우 도어 외부의 표면 온도를 낮게 유지할 수 있는 쿨링 구조를 필요로 한다.In particular, the oven needs a cooling structure capable of maintaining a low surface temperature outside the door in the case of the cleaning mode because the temperature inside the cooking compartment increases significantly in the case of the cleaning mode than in the case of the general cooking mode.

A detailed description of the opening and closing device 100 will be described below.
다음으로, 도어(30) 내부의 고온의 공기가 도어(30) 외부로 토출되고, 도어(30) 외부로 토출된 고온의 공기가 오븐 외부로 배출되는 공기의 유동을 설명하도록 한다.Next, the flow of air in which the hot air inside the door 30 is discharged to the outside of the door 30 and the hot air discharged to the outside of the door 30 is discharged to the outside of the oven will be described.
도어(30) 하부에 마련된 공기 유입구(39, 도 3 참조)로 흡입된 공기는 도어(30) 내부에서 온도가 높아지면서 상부 방향으로 이동될 수 있다. 공기 유입구(39, 도 3 참조)로 흡입된 공기는 조리실(20) 내부의 온도에 의해 온도가 높아진 도어(30) 외부의 표면 온도를 낮추면서 온도가 높아질 수 있다. 도어(30) 내부의 고온의 공기는 도어(30) 상부로 이동되어 토출홀(35)을 통해 도어(30) 외부로 토출될 수 있다. 토출홀(35)로 토출된 고온의 공기 중 일부는 냉각팬(51)에 의해 강제로 흡입홀(12)로 흡입될 수 있다. 흡입홀(12)로 흡입된 고온의 공기는 흡입덕트(70)에 의해 가이드 되어 냉각팬(51)으로 흡입될 수 있다. 흡입덕트(70)에 의해 가이드 된 공기가 냉각팬(51)으로 흡입될 수 있도록 배출덕트(80)는 흡입개구(81)를 포함할 수 있다. 냉각팬(51)으로 흡입된 고온의 공기는 배출덕트(80)에 의해 가이드되어 배출구(83)로 배출될 수 있다. 배출구(83)로 배출된 고온의 공기는 배출부(85)를 통해 오븐 외부로 배출될 수 있다.Air sucked through the air inlet 39 (refer to FIG. 3) provided under the door 30 may be moved upward as the temperature increases inside the door 30. The air sucked through the air inlet 39 (refer to FIG. 3) may increase in temperature while lowering the surface temperature of the outside of the door 30, which has increased temperature due to the temperature inside the cooking chamber 20. The hot air inside the door 30 may be moved to the upper portion of the door 30 and discharged to the outside of the door 30 through the discharge hole 35. Some of the hot air discharged through the discharge hole 35 may be forcibly sucked into the suction hole 12 by the cooling fan 51. The high temperature air sucked into the suction hole 12 may be guided by the suction duct 70 and sucked into the cooling fan 51. The discharge duct 80 may include a suction opening 81 so that the air guided by the suction duct 70 can be sucked into the cooling fan 51. The hot air sucked by the cooling fan 51 may be guided by the discharge duct 80 and discharged to the discharge port 83. The high temperature air discharged through the discharge port 83 may be discharged to the outside of the oven through the discharge part 85.
토출홀(35)로 토출된 고온의 공기 중 나머지 일부는 벤츄리 효과에 의해 갭(G)을 통해 배출부(85)로 배출될 수 있다. 이에 대해 자세히 설명하면, 냉각팬(51)에 의해 배출부(85)로 배출되는 공기의 유속에 의해 배출부(85)에는 저압 영역이 발생될 수 있다. 배출부(85)에 저압 영역이 발생되면 토출홀(35)로 토출된 고온의 공기는 배출부(85)와 연통된 갭(G)을 통해 배출부(85)로 배출될 수 있다. 배출부(85)로 배출된 고온의 공기는 오븐의 외부로 배출될 수 있다.The remaining part of the hot air discharged through the discharge hole 35 may be discharged to the discharge unit 85 through the gap G due to the venturi effect. In detail, a low pressure region may be generated in the discharge part 85 by the flow velocity of air discharged to the discharge part 85 by the cooling fan 51. When a low pressure region is generated in the discharge part 85, the hot air discharged through the discharge hole 35 may be discharged to the discharge part 85 through a gap G communicated with the discharge part 85. The high-temperature air discharged through the discharge unit 85 may be discharged to the outside of the oven.
따라서, 도어(30) 내부의 고온의 공기는 벤츄리 효과를 이용한 방식 및 냉각팬(51)에 의한 강제 흡입을 이용한 방식 모두를 통해 오븐 외부로 배출될 수 있다. 이로 인해, 조리실(20)의 용량을 확보하면서 도어(30) 외부의 표면 온도를 효율적으로 낮출 수 있다. 상기와 같은 2가지 방식이 모두 원활하게 발생될 수 있도록 토출홀(35)의 크기는 흡입홀(12)의 크기와 동일하거나, 더 크게 형성될 수 있다.Accordingly, the high-temperature air inside the door 30 can be discharged to the outside of the oven through both a method using a venturi effect and a method using forced suction by the cooling fan 51. Accordingly, while securing the capacity of the cooking chamber 20, the surface temperature of the outside of the door 30 can be efficiently reduced. The size of the discharge hole 35 may be equal to or larger than the size of the suction hole 12 so that both of the above-described methods can be smoothly generated.
오븐 동작 시 오븐의 에너지 손실은 조리실(20)에 의한 에너지 손실이 대략 76%이고, 오븐을 구성하는 각종 구조물 자체의 온도 상승에 의한 열용량에 의한 에너지 손실이 대략 14%이고, 도어(30)를 통한 에너지 손실이 대략 10%이다. 도어(30) 외부의 표면 온도를 낮추기 위한 쿨링 구조가 개선되면 도어(30) 외부의 표면 온도는 낮출 수 있지만, 도어(30)를 통한 에너지 손실은 증가될 수 있다. 도어(30)를 통한 에너지 손실을 감소시키기 위해서는 도어(30) 내부의 공기 순환이 최소화되는 것이 유리할 수 있다. 따라서, 오븐의 동작에 따라 도어(30) 외부의 표면 온도를 낮추거나, 도어(30)를 통한 에너지 손실을 감소시킬 수 있도록 조절할 필요가 있다. 이를 위해 흡입유로(35, 12, 70) 상에는 흡입유로(35, 12, 70)를 선택적으로 개폐하는 개폐장치(100)가 마련될 수 있다.As for the energy loss of the oven during operation, the energy loss due to the cooking chamber 20 is about 76%, the energy loss due to the heat capacity due to the temperature increase of the various structures constituting the oven itself is about 14%, and the door 30 is closed. The energy loss through is approximately 10%. If the cooling structure for lowering the outer surface temperature of the door 30 is improved, the outer surface temperature of the door 30 may be lowered, but energy loss through the door 30 may increase. In order to reduce energy loss through the door 30, it may be advantageous to minimize air circulation inside the door 30. Therefore, according to the operation of the oven, it is necessary to lower the surface temperature of the outside of the door 30 or adjust it so as to reduce energy loss through the door 30. To this end, an opening/closing device 100 for selectively opening and closing the suction passages 35, 12 and 70 may be provided on the suction passages 35, 12, and 70.

The cover switch 63 may be provided on the door lock switch 61 of the door lock device 60. When the door lock switch 61 is in the unlocked state in the locking part 37, the cover switch 63 may be in a state spaced apart from the rotating part 140. In this case, the cover 130 may be in a state in which the suction hole 12 is closed. When the suction hole 12 is closed, the hot air inside the door 30 can be discharged to the outside of the oven only by a method using the Venturi effect. In the cooking mode, when the temperature inside the cooking chamber 20 is relatively low, the opening and closing device 100 closes the suction hole 12 to properly lower the surface temperature outside the door 30 while circulating air inside the door 30 Energy loss can be reduced by ensuring that this is minimized.
오븐의 동작이 청소 모드일 때는 도어 잠금 스위치(61)가 잠금부(37)에 잠금 상태일 수 있다. 도어 잠금 스위치(61)가 잠금부(37)에 잠금 상태일 때, 커버 스위치(63)는 회전부(140)에 접촉되어 회전축(120)을 회전시킬 수 있다. 회전축(120)이 회전되면 커버(130)는 회전축(120)과 함께 회전되어 흡입홀(12)을 개방할 수 있다.흡입홀(12)이 개방된 상태에서 도어(30) 내부의 고온의 공기는 벤츄리 효과를 이용한 방식 및 냉각팬(51)에 의한 강제 흡입을 이용한 방식 모두를 통해 오븐 외부로 배출되기 때문에, 도어(30) 외부의 표면 온도를 최대한 낮출 수 있다. 조리실(20) 내부의 온도가 상대적으로 높은 청소 모드일 때는 개폐장치(100)가 흡입홀(12)을 개방하여 도어(30) 외부의 표면 온도를 최대한 낮추도록 할 수 있다.When the oven is operated in the cleaning mode, the door lock switch 61 may be locked to the lock part 37. When the door lock switch 61 is locked to the locking part 37, the cover switch 63 may contact the rotating part 140 to rotate the rotating shaft 120.

다음으로, 오븐의 동작에 따라 개폐장치(100)가 흡입홀(12)을 선택적으로 개폐하는 동작에 대해 자세히 살펴보도록 한다.Next, the operation of the opening/closing device 100 selectively opening and closing the suction hole 12 according to the operation of the oven will be described in detail.
도 8은 본 발명의 일실시예에 따른 오븐이 조리 모드일 때, 도어 잠금 스위치가 잠금부에서 잠금 해제되어 개폐장치에 의해 흡입홀이 폐쇄된 모습을 도시한 도면이고, 도 9는 본 발명의 일실시예에 따른 개폐장치에 의해 흡입홀이 폐쇄된 상태에서 도어 내부의 고온의 공기가 오븐 외부로 배출되는 공기의 유동을 도시한 도면이다.FIG. 8 is a view showing a state in which the door lock switch is unlocked at the lock portion and the suction hole is closed by the opening and closing device when the oven is in the cooking mode according to an embodiment of the present invention. It is a view showing the flow of air discharged to the outside of the oven of hot air inside the door in a state in which the suction hole is closed by the opening and closing device according to an embodiment.
도 8 내지 도 9에 도시된 바와 같이, 오븐의 동작이 조리 모드일 때는 도어 잠금 스위치(61)가 잠금부(37)에서 잠금 해제된 상태일 수 있다. 이때, 커버 스위치(63)는 회전부(140)와 이격되고, 커버(130)는 흡입홀(12)을 폐쇄한 상태일 수 있다. 흡입홀(12)이 커버(130)에 의해 폐쇄된 상태에서 도어(30) 내부의 고온의 공기는 토출홀(35)을 통해 도어(30) 외부로 토출될 수 있다. 흡입홀(12)이 폐쇄되어 있기 때문에, 토출홀(35)을 통해 토출된 고온의 공기는 갭(G)을 통해 배출부(85)로 배출될 수 있다. 이는 냉각팬(51)에 의해 전장실(50)로 흡입된 후 배출유로(80, 85)에 의해 가이드되어 오븐의 전방으로 배출되는 공기의 유속에 의해 발생되는 벤츄리 효과에 의해 이루어질 수 있다.As shown in FIGS. 8 to 9, when the oven is in the cooking mode, the door lock switch 61 may be unlocked by the lock part 37. In this case, the cover switch 63 may be spaced apart from the rotating part 140, and the cover 130 may be in a state in which the suction hole 12 is closed. When the suction hole 12 is closed by the cover 130, hot air inside the door 30 may be discharged to the outside of the door 30 through the discharge hole 35. Since the suction hole 12 is closed, the high temperature air discharged through the discharge hole 35 may be discharged to the discharge unit 85 through the gap G. This may be achieved by a venturi effect generated by the flow velocity of air that is sucked into the electrical room 50 by the cooling fan 51 and then guided by the discharge passages 80 and 85 and discharged to the front of the oven.
따라서, 도어(30) 내부의 고온의 공기는 벤츄리 효과를 이용한 방식에 의해서만 오븐 외부로 배출될 수 있다. 이로 인해, 조리실(20) 내부의 온도가 상대적으로 낮은 조리 모드일 때는 도어(30) 외부의 표면 온도를 적당히 낮추면서 도어(30) 내부의 공기 순환이 최소화되도록 하여 에너지 손실을 감소시킬 수 있다.Accordingly, the hot air inside the door 30 can be discharged to the outside of the oven only by a method using the Venturi effect. For this reason, in the cooking mode in which the temperature inside the cooking chamber 20 is relatively low, the surface temperature outside the door 30 is appropriately lowered and air circulation inside the door 30 is minimized, thereby reducing energy loss.

This may be achieved by a venturi effect generated by the flow velocity of air that is sucked into the electrical room 50 by the cooling fan 51 and then guided by the discharge passages 80 and 85 and discharged to the front of the oven.
따라서, 도어(30) 내부의 고온의 공기는 벤츄리 효과를 이용한 방식 및 냉각팬(51)에 의한 강제 흡입을 이용한 방식 모두를 통해 오븐 외부로 배출될 수 있다. 이로 인해, 조리실(20) 내부의 온도가 상대적으로 높은 청소 모드일 때는 도어(30) 외부의 표면 온도를 최대한 낮출 수 있다.Accordingly, the high-temperature air inside the door 30 can be discharged to the outside of the oven through both a method using a venturi effect and a method using forced suction by the cooling fan 51. For this reason, in the cleaning mode in which the temperature inside the cooking chamber 20 is relatively high, the surface temperature outside the door 30 can be reduced as much as possible.

도 13은 본 발명의 다른 실시예에 따른 오븐이 조리 모드일 때, 도어 잠금 스위치가 잠금부에서 잠금 해제된 모습을 도시한 도면이고, 도 14는 본 발명의 다른 실시예에 따른 도어 잠금 스위치가 잠금부에서 잠금 해제되어 개폐장치에 의해 토출홀이 폐쇄된 상태에서 도어 내부의 고온의 공기가 오븐 외부로 배출이 방지된 모습을 도시한 도면이다.13 is a diagram illustrating a state in which a door lock switch is unlocked from a lock when the oven is in a cooking mode according to another embodiment of the present invention, and FIG. 14 is a view showing a door lock switch according to another embodiment of the present invention. It is a view showing a state in which the hot air inside the door is prevented from being discharged to the outside of the oven in a state where the discharge hole is closed by the opening and closing device by being unlocked by the locking part.
도 13 내지 도 14에 도시된 바와 같이, 오븐의 동작이 조리 모드일 때는 도어 잠금 스위치(61)가 잠금부(37)에서 잠금 해제된 상태일 수 있다. 이때, 도어 잠금 스위치(61)는 접촉부(250)와 이격되고, 커버(230)는 토출홀(35)을 폐쇄한 상태일 수 있다. 토출홀(35)이 커버(230)에 의해 폐쇄된 상태에서 도어(30) 내부의 고온의 공기는 도어(30) 외부로 배출되는 것이 방지될 수 있다. 이로 인해, 조리실(20) 내부의 온도가 상대적으로 낮은 조리 모드일 때는 도어(30) 내부의 고온의 공기 도어(30) 외부로 배출되지 못하도록 하여 에너지 손실을 감소시킬 수 있다.As shown in FIGS. 13 to 14, when the oven is in the cooking mode, the door lock switch 61 may be unlocked by the lock unit 37. In this case, the door lock switch 61 may be spaced apart from the contact part 250, and the cover 230 may be in a state in which the discharge hole 35 is closed. When the discharge hole 35 is closed by the cover 230, hot air inside the door 30 may be prevented from being discharged to the outside of the door 30. Accordingly, in the cooking mode in which the temperature inside the cooking chamber 20 is relatively low, the hot air inside the door 30 is prevented from being discharged to the outside of the door 30, thereby reducing energy loss.
도 15는 본 발명의 다른 실시예에 따른 오븐이 청소 모드일 때, 도어 잠금 스위치가 잠금부에 잠금된 모습을 도시한 도면이고, 도 16은 본 발명의 다른 실시예에 따른 도어 잠금 스위치가 잠금부에 잠금되어 개폐장치가 토출홀을 개방한 상태에서 도어 내부의 고온의 공기가 오븐 외부로 배출되는 공기의 유동을 도시한 도면이다.15 is a view showing a state in which the door lock switch is locked to the locking unit when the oven is in the cleaning mode according to another embodiment of the present invention, and FIG. 16 is a door lock switch according to another embodiment of the present invention. It is a view showing the flow of air through which the hot air inside the door is discharged to the outside of the oven in a state where the opening and closing device is locked to the part to open the discharge hole.
도 15 내지 도 16에 도시된 바와 같이, 오븐의 동작이 청소 모드일 때는 도어 잠금 스위치(61)가 잠금부(37)에 잠금된 상태일 수 있다. 이때, 도어 잠금 스위치(61)는 접촉부(250)에 접촉되어 접촉부(250)를 눌러줄 수 있다. 이로 인해 회전부(240)는 회전될 수 있다. 또한, 회전부(240)와 링크(270)에 의해 연결된 회전축(220)도 회전될 수 있다. 회전축(220)이 회전되면, 커버(230)는 회전축(220)과 함께 회전되어 토출홀(35)을 개방할 수 있다. 토출홀(35)이 개방된 상태에서 도어(30) 내부의 고온의 공기는 토출홀(35)을 통해 도어(30) 외부로 토출될 수 있다. 토출홀(35)로 토출된 고온의 공기 중 일부는 냉각팬(51, 도 4 참조)에 의해 흡입홀(12)로 흡입될 수 있다. 흡입홀(12)로 흡입된 고온의 공기는 흡입덕트(70)에 의해 가이드되어 흡입개구(81)를 통해 냉각팬(51, 도 4 참조)으로 흡입될 수 있다. 냉각팬(51, 도 4 참조)으로 흡입된 고온의 공기는 배출유로(80, 85)를 통해 오븐 외부로 배출될 수 있다.As shown in FIGS. 15 to 16, when the oven is in the cleaning mode, the door lock switch 61 may be locked to the locking part 37. In this case, the door lock switch 61 may contact the contact part 250 to press the contact part 250. Accordingly, the rotating part 240 may be rotated. In addition, the rotation shaft 220 connected by the rotation unit 240 and the link 270 may also be rotated. When the rotation shaft 220 is rotated, the cover 230 may be rotated together with the rotation shaft 220 to open the discharge hole 35. When the discharge hole 35 is open, the hot air inside the door 30 may be discharged to the outside of the door 30 through the discharge hole 35. Some of the hot air discharged through the discharge hole 35 may be sucked into the suction hole 12 by a cooling fan 51 (see FIG. 4 ). The hot air sucked into the suction hole 12 is guided by the suction duct 70 and may be sucked into the cooling fan 51 (see FIG. 4) through the suction opening 81. The high-temperature air sucked in by the cooling fan 51 (refer to FIG. 4) may be discharged to the outside of the oven through the discharge passages 80 and 85.
토출홀(35)로 토출된 고온의 공기 중 나머지 일부는 갭(G)을 통해 배출부(85)로 배출될 수 있다. 이는 냉각팬(51)에 의해 전장실(50)로 흡입된 후 배출유로(80, 85)에 의해 가이드되어 오븐의 전방으로 배출되는 공기의 유속에 의해 발생되는 벤츄리 효과에 의해 이루어질 수 있다.The remaining part of the hot air discharged through the discharge hole 35 may be discharged to the discharge unit 85 through the gap G. This may be achieved by a venturi effect generated by the flow velocity of air that is sucked into the electrical room 50 by the cooling fan 51 and then guided by the discharge passages 80 and 85 and discharged to the front of the oven.
따라서, 도어(30) 내부의 고온의 공기는 벤츄리 효과를 이용한 방식 및 냉각팬(51)에 의한 강제 흡입을 이용한 방식 모두를 통해 오븐 외부로 배출될 수 있다. 이로 인해, 조리실(20) 내부의 온도가 상대적으로 높은 청소 모드일 때는 도어(30) 외부의 표면 온도를 최대한 낮출 수 있다.Accordingly, the high-temperature air inside the door 30 can be discharged to the outside of the oven through both a method using a venturi effect and a method using forced suction by the cooling fan 51. For this reason, in the cleaning mode in which the temperature inside the cooking chamber 20 is relatively high, the surface temperature outside the door 30 can be reduced as much as possible.
오븐의 동작이 다시 조리 모드가 되면, 도 13 내지 도 14에 도시된 바와 같이, 도어 잠금 스위치(61)는 잠금부(37)에서 잠금 해제될 수 있다, 이때, 도어 잠금 스위치(61)가 접촉부(250)에서 이격되면서 접촉부(250)를 눌러주는 힘이 해제될 수 있다. 접촉부(250)를 눌러주는 힘이 해제되면 회전부(240)는 토션스프링(260)에 의해 회전되기 전의 위치로 다시 회전될 수 있다. 회전부(240)가 회전되기 전의 위치로 다시 회전되면 회전축(220)도 회전되기 전의 위치로 다시 회전될 수 있다. 회전축(220)도 회전되기 전의 위치로 다시 회전되면, 커버(230)는 회전축(220)과 함께 다시 회전되어 토출홀(35)을 폐쇄할 수 있다.When the operation of the oven enters the cooking mode again, as shown in FIGS. 13 to 14, the door lock switch 61 can be unlocked by the lock part 37. At this time, the door lock switch 61 As spaced apart from 250, a force pressing the contact part 250 may be released. When the force pressing the contact part 250 is released, the rotation part 240 may be rotated back to the position before rotation by the torsion spring 260. When the rotating part 240 is rotated back to the position before being rotated, the rotating shaft 220 may also be rotated back to the position before being rotated. When the rotation shaft 220 is also rotated back to the position before rotation, the cover 230 may be rotated again together with the rotation shaft 220 to close the discharge hole 35.
이상에서 첨부된 도면을 참조하여 오븐을 설명함에 있어 특정 형상 및 방향을 위주로 설명하였으나, 이는 통상의 기술자에 의하여 다양한 변형 및 변경이 가능하고, 이러한 변형 및 변경은 본 발명의 권리범위에 포함되는 것으로 해석되어야 한다.In the description of the oven with reference to the accompanying drawings above, a specific shape and direction have been described, but various modifications and changes are possible by a person skilled in the art, and such modifications and changes are included in the scope of the present invention. It must be interpreted.
