Medications are certain substances (may be chemicals or natural substances) that are used to treat ailments or relieve symptoms. Depending on the type of medication, they can be altered or lose the efficacy of the original medication. It can cause serious side effects.

In other words, medicines should be stored in different ways. For example, pills should be stored in the original medicine container at room temperature, avoiding direct sunlight, and most powdered medicines have a shorter shelf life and weaker moisture than pills. Store in a dry place and avoid high humidity refrigerators or bathroom shelves. For syrups, which are commonly used as children's antipyretics, they should be kept refrigerated. Some medicines are better to keep warm and take them like hot water. As such, the storage of medicines requires a refrigerator and a refrigerator, which can be simultaneously implemented as a function of refrigeration and warming.

Thus, the technology for the refrigerator and the refrigerator, in which the functions of the refrigerator and the heating, are simultaneously implemented, has been developed. However, since one storage compartment has to be used for refrigerating or for heating, the function of either the refrigerator or the greenhouse is not necessary. Or if one more function is needed, there was a limit in utilizing the cold and warm room.

An object of the present invention is to diversify the use of cold and hot refrigerator in order to solve the above problems.

It is characterized in that it comprises a second thermoelectric semiconductor consisting of a heat generating surface and the heat absorbing surface is an endothermic action provided in the current is applied,

The first thermoelectric semiconductor and the second thermoelectric semiconductor are individually controlled to operate,

Heat exchange to help heat exchange between the heat generating surface and the heat absorbing surface of the first thermoelectric semiconductor, which do not face the first storage chamber, and the surface which does not face the second storage chamber among the heat generating surface and the heat absorbing surface of the second thermoelectric semiconductor. It further comprises a device as a specific feature,

Can be used in various ways, and only one storage room can be used as needed, resulting in economic effects.

With reference to the accompanying drawings, a preferred embodiment of the present invention will be described in more detail, but already known technical parts will be omitted or compressed for the sake of brevity of description.

1 is a cross-sectional view of a medical cold and warm refrigerator according to the present invention,

Referring to FIG. 1, the medical cold / warmer 100 according to the present invention may open and close two storage chambers for storing medicines, that is, a first storage chamber 111 and a second storage chamber 112 and each storage chamber. The first door 110a and the second door 110b are formed of a housing 110, a first thermoelectric conductor 120, a second thermoelectric conductor 130, and a heat exchanger 140.

Each surface of the first storage chamber 111 and the second storage chamber 112 is provided with doors (110a, 110b) that is selectively opened and closed, can be used independently,

The first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 120 having a heat generating surface for generating heat and an endothermic surface for absorbing heat as current is applied to opposite wall surfaces of the storage chambers 111 and 112 facing the doors 111a and 112a. The thermoelectric semiconductor 130 is installed to individually control the flow of current by switching to selectively function as a refrigerating chamber or a warm room or may not be used as necessary.

The thermoelectric semiconductors 120 and 130 are generic terms of devices using various effects represented by the interaction between heat and electricity. Thermistors used for stabilization of circuits, heat, power, light, and detection, and the Seebeck effect used to measure temperature are used. Peltier devices used for the production of devices, refrigerators and thermostats. Among them, the Peltier effect using the Peltier element utilized in the present invention is a phenomenon in which, when two types of metal tips are connected and a current is flowed therein, one terminal absorbs heat and the other terminal generates heat in the current direction. If a semiconductor such as bismuth or tellurium having different battery conduction methods is used instead of two kinds of metals, a Peltier device having an efficient endothermic and heat generating effect can be obtained. It is possible to switch the endotherm and the heat generation according to the current direction, and the endotherm and the heat generation amount are adjusted according to the amount of current, so it is applied to the manufacture of a precision refrigerator or a small temperature chamber near a low temperature.

When the storage compartments 111 and 112 function as the refrigerating compartment, one surface 120a and 130a of the thermoelectric semiconductors 120 and 130 connected to the refrigerating compartment are endothermic surfaces that absorb and cool heat, and the other surfaces 120b and 130b on the opposite side are It becomes a heat generating surface which exothermic action which ejects the heat absorbed from the heat absorbing surface. On the other hand, when it functions as a warm room, one surface (120a, 130a) of the thermoelectric semiconductor connected to the warm room is a heat generating surface for exothermic action and the other surface (120b, 130b) on the opposite side is an endothermic surface for endothermic action. The position of the heat absorbing surface and the heat generating surface is controlled in the direction of the current as can be seen from the characteristics of the thermoelectric element.

The heat exchange device 140, which is another configuration of the present invention, is a device for assisting heat exchange of the other surfaces 120b and 130b of the thermoelectric semiconductors 120 and 130, and a heat exchanger 141 in which the introduced fluid is heat exchanged. The first connecting portion 142 connecting the thermoelectric semiconductor 120 and the heat exchanger 141, the second connecting portion 143 connecting the second thermoelectric semiconductor 130 and the heat exchanger 141, and the first thermoelectric semiconductor. It is composed of a third connecting portion 144 that connects the 120 and the second thermoelectric semiconductor 130 dependently. Due to the configuration of the heat exchanger 140, the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 are not only connected to the heat exchanger 141 but also connected to each other, so that the first storage chamber 111 and the second heat exchanger 140 are connected to each other. According to the use of the storage compartment 112, the heat exchange is primarily performed between the thermoelectric semiconductors 120 and 130 by natural convection, and secondly, the heat exchange is performed in the heat exchanger 141.

The heat exchanger 140 is a device that transfers heat from a fluid having a high temperature to a fluid having a low temperature through a heat transfer wall, and is used in a heater, a cooler, an evaporator, a condenser, and the like. The heat transfer medium used to heat the fluid of interest is called the fruit, and on the contrary, the heat transfer medium is called the refrigerant. The most commonly used type of heat exchanger is metal pipes with heat-transfer walls. These types include main type, double type, finned tube and bushing type. The double tube heat exchanger has an inner tube and an outer tube, and heat exchange is performed between the fluid inside the inner tube and the annular fluid between the tube and the tube. This format is simple in structure but requires less processing. Larger ones use a bushing type with a large appearance and several small tubes. Flowing in the same direction in the flow of high fluid or low fluid flows in the opposite direction to the co-flow type. Common heat transfer media used in industry include water, water vapor, air, flue gas, petroleum, mercury, sodium, potassium, and dowsome, a mixture of biphenylether and biphenyl.

The operation of the medical cold / refrigerator according to an embodiment of the present invention will be described as follows with reference to FIG.

An example of the use of the cold and warm storage 100 can be divided into eight cases as shown in Table 1.

division First Storage Room 111 Second Storage Room 112 Remarks Case 1 Warmth cold storage Standard
Terms of use Case 2 cold storage cold storage Select control
Terms of use Case 3 Warmth Warmth Case 4 Warmth OFF Case 5 cold storage OFF Case 6 OFF cold storage Case 7 OFF Warmth

In the above seven cases, it is a standard use condition having functions of general refrigerators and refrigerators, that is, a function of a refrigerator compartment and a kitchen compartment, and a selection control use condition in which two storage compartments use only one function or only one of the two storage compartments. Divided.

Each case described in Table 1 above will be described as follows.

First, in the case of standard use condition that functions as a general refrigerator and refrigerator,

By changing the direction of current flow, the first thermoelectric of the thermoelectric semiconductors 120 and 130 installed in the first storage chamber 111 and the second storage chamber 112 using the characteristics of the thermoelectric semiconductors 120 and 130 that the function of the heat absorbing surface and the heat generating surface is converted. In the semiconductor 120, the heating surface 120a generates heat to heat the heating chamber, and the second thermoelectric semiconductor 130 cools the refrigerator compartment by absorbing the heat absorbing surface 130a. At this time, the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 mounted in each storage chamber are connected to each other by the third connection part 144. The hot heat generated by the heat generation 130b of the second thermoelectric semiconductor 130 is performed. The heat is generated by the natural convection through the third connecting portion 144, the warming effect of the first storage compartment 111 is compensated by the heat rising to the rear of the first storage compartment 111 by the natural convection, so that Also, the efficiency of the refrigerator and the refrigerator is improved.

Next, when the two storage compartments have the same function, the case 3 and the case 4, the heat absorbing surface (120a, 130a) of each thermoelectric semiconductor (120, 130) is cooled when the two storage compartments (111, 112) are all refrigerated through selective control As a result of the endothermic operation, the refrigerating chamber is cooled and generates heat at the heat generating surfaces 120b and 130b of the thermoelectric semiconductors 120 and 130. At this time, heat exchange does not occur between the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 mounted in each of the storage chambers 111 and 112, and the generated heat is transferred to the heat exchanger 141 through the fluid to be heat exchanged.

In addition, when the two storage chambers function as a warm field, the heat generating surfaces 120a and 130a of the storage chambers 111 and 112 generate heat by using the characteristics of the thermoelectric semiconductor that the function of the heat absorbing surface and the heat generating surface changes when the direction of current flow is changed. The heating chamber is heated by the operation, and the endothermic reaction is performed on the heat absorbing surfaces 120b and 130b of the thermoelectric semiconductors 120 and 130. At this time, heat exchange does not occur between the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 mounted in each of the storage chambers 111 and 112, and the cooled heat is transferred to the heat exchanger 141 through the fluid to be heat exchanged.

Finally, when only one of the two storage compartments 111 and 112 is used, 5, 6, 7, and 8, the endothermic surface 120a of the refrigerating compartment is used when one side is refrigerated and the other side is not used. And 130a are cooled to endothermic to cool the refrigerating chamber, and to generate heat at the heat generating surfaces 120b and 130b of the thermoelectric semiconductors 120 and 130. At this time, heat exchange does not occur between the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 mounted in each of the storage chambers 111 and 112, and the absorbed heat is transferred to the heat exchanger 141 through the fluid to be heat exchanged.

Alternatively, when one side is warm and the other side is not in use, the heat generating surfaces 120a and 130a of the storage chamber operate by using the characteristics of the thermoelectric elements which change the function of the heat absorbing surface and the heat generating surface when the current flow direction is changed. The warm room is heated, and the endothermic reaction is performed on the heat absorbing surfaces 120b and 130b of the thermoelectric semiconductors 120 and 130. At this time, heat exchange does not occur between the first thermoelectric semiconductor 120 and the second thermoelectric semiconductor 130 mounted in each of the storage chambers 111 and 112, and the cooled heat is transferred to the heat exchanger 141 through the fluid to be heat exchanged.
