도 2는 본 발명의 일 실시예에 따른 냉온 보관 케이스의 내부 블록도이다. 2 is an internal block diagram of a cold storage case according to an embodiment of the present invention.
본 발명의 일 실시예에 따른 냉온 보관 케이스는, 음식물 또는 음식물이 담긴 용기가 놓여지는 플레이트부(100), 상기 플레이트부(100)에 설치되고 무선전력을 수신하는 수신 코일을 포함하는 무선전력 수신부(120), 공급되는 전압의 극성에 따라 냉장 또는 온장하는 열전소자부(130) 및, 상기 무선전력 수신부(120)로부터 상기 열전소자부(130)로 공급되는 전압의 극성을 설정하는 제어부(110)를 포함할 수 있다.Cold storage case according to an embodiment of the present invention, a wireless power receiver including a plate portion 100 is placed on the container containing food or food, a receiving coil installed in the plate portion 100 to receive wireless power 120, the thermoelectric element 130 refrigerated or warmed according to the polarity of the supplied voltage, and the controller 110 setting the polarity of the voltage supplied from the wireless power receiver 120 to the thermoelectric element 130. ) May be included.

한편, 상기 열전소자부(130)는 하나 이상의 열전소자를 포함할 수 있다.On the other hand, the thermoelectric element 130 may include one or more thermoelectric elements.
상기 열전소자는, 펠티어(peltier) 현상에 의해 나타나는 냉각 또는 가열효과를 이용하는 것으로, 인가되는 전류의 방향에 따라서 발열반응 또는 흡열반응을 할 수 있다. The thermoelectric element utilizes a cooling or heating effect exhibited by a peltier phenomenon, and may exothermic or endothermic according to the direction of the applied current.
열전소자에 DC 전류를 공급할 경우 열전효과에 의해서 열전소자의 양면에 온도차가 발생된다. 더욱 상세하게는 열전소자의 전극에 직류 전원을 인가하면 일측에서는 열이 발생되고 타측에서는 열을 흡수하게 된다. 또한, 전원의 극성을 서로 바꾸면 열이 흡수되고 방출되는 방향을 변화시킬 수 있게 된다.When DC current is supplied to the thermoelectric element, a temperature difference occurs on both sides of the thermoelectric element due to the thermoelectric effect. More specifically, when DC power is applied to the electrode of the thermoelectric element, heat is generated on one side and absorbs heat on the other side. In addition, changing the polarity of the power source can change the direction in which heat is absorbed and released.
한편, 상기 전극에 인가되는 전류의 흐름을 반대로 바꾸면, 즉, 열전소자로 공급되는 전압의 극성을 반대로 변경하면, 열이 발생되던 일측에서는 열이 흡수되고, 열이 흡수되는 타측에서는 열이 발생할 수 있다.On the other hand, if the flow of current applied to the electrode is reversed, that is, if the polarity of the voltage supplied to the thermoelectric element is reversed, heat may be absorbed on one side where heat is generated and heat may be generated on the other side where heat is absorbed. have.
따라서, 본 발명은, 상기 제어부(110)가 냉장 모드, 온장 모드 여부에 따라서 열전소자부(130)로 공급되는 전압의 극성을 설정함으로써, 각 모드에 대응하도록 열전소자가 냉장 또는 온장 기능을 수행할 수 있다.Therefore, according to the present invention, the control unit 110 sets the polarity of the voltage supplied to the thermoelectric element unit 130 according to the refrigeration mode, the warm mode, so that the thermoelectric element performs the refrigerating or warming function corresponding to each mode. can do.
또는, 사용자의 목표 온도 설정에 따라서, 상기 제어부(110)는 냉장 또는 온장 기능을 선택하고 그에 따라 열전소자부(130)로 공급되는 전압의 극성을 설정할 수 있다.Alternatively, according to the user's target temperature setting, the control unit 110 may select the refrigerating or warming function and set the polarity of the voltage supplied to the thermoelectric element 130 accordingly.
열전소자부(130)로 공급되는 전압의 극성에 따라 열전소자부(130)의 방열작용과 흡열작용의 방향이 결정된다. 그러므로, 냉온 보관 케이스의 내측, 플레이트부(100)의 상측방향에서 이루어지는 방열작용과 흡열작용의 방향을 전압의 극성으로 결정함으로써, 냉온 보관 케이스의 내부를 온장 케이스 또는 냉장 케이스로써 사용할 수 있다.The direction of heat dissipation and endothermic action of the thermoelectric element 130 is determined according to the polarity of the voltage supplied to the thermoelectric element 130. Therefore, the inside of the cold storage case can be used as a warming case or a refrigeration case by determining the direction of the heat dissipation action and the heat absorption action in the upper side of the cold storage case and the plate portion 100 as the polarity of the voltage.
또한, 냉온 보관 케이스의 내부를 별도로 구획하지 않고, 용도에 따라 냉온 보관 케이스 내부 전체를 온장 케이스 또는 냉장 케이스로 사용할 수 있다.In addition, the whole inside of a cold storage case can be used as a warming case or a cold storage case according to a use, without dividing the inside of a cold storage case separately.
한편, 열전소자는 여러가지 방식으로 구현될 수 있다. 예를 들어, 전극사이에 N, P형 반도체들이 교대로 배치되는 모듈 형태로 구현될 수 있다. 한편, N, P형 반도체들은 전기적으로 직렬 접속될 수 있고, 전류가 각 N형 반도체로부터 P형 반도체로 흐를때 펠티에 효과로 인해 열이 상부에서 흡수되고, 그 하부를 통하여 방출될 수 있다.On the other hand, the thermoelectric element may be implemented in various ways. For example, it may be implemented in the form of a module in which N, P-type semiconductors are alternately arranged between the electrodes. On the other hand, the N and P-type semiconductors may be electrically connected in series, and heat may be absorbed at the top and released through the bottom when the current flows from each N-type semiconductor to the P-type semiconductor.
