Description

A cooling and heating apparatus without environmental pollution}

The present invention relates to a cold / cold storage for both cold and hot temperatures that can simultaneously perform the functions of a refrigerator and a warmer, and in particular, by using a thermoelectric element (Peltier device) to perform cooling and warming of an object, The present invention relates to an environment-friendly, cold-free refrigerator that does not use refrigerant gas such as Freon, which is an environmental pollutant that causes pollution, while having a separate refrigerated space and a heat insulating space.

In general, when travelers want to drink cold or hot beverages, they buy and drink beverages at travel destinations or roadside shops, and when they are traveling by car or do not have any shops selling drinks, they are stressed by thirst. Will receive. In particular, even if a drink is purchased in advance and stored in a car, it is difficult to quench thirst on a hot day because the beverage already purchased and prepared inside the car becomes hot.

Moreover, parents with children often need to carry drinking water or drinks to feed powdered milk or for children's beverages.In hot days, such as summer, tea is kept at home or in shops to quench thirst and cool the heat. Even if you buy and carry warm water or drinks, your cold water and cold beverages will heat up after a certain period of time, and you will not be able to satisfactorily quench your thirst or heat.

On the other hand, in winter, drinking hot water in the open air often helps to maintain the body temperature, so often carry a hot water. However, even in this case, there are many difficulties in storing and carrying.

Therefore, the thermos may be used to carry cold water and hot water. However, if the thermos is frequently opened, the contents easily change to room temperature, and even if it is not opened, after a certain time, the cold water is hot and the hot water is cold, and there is a discontinuation of drinking in a desired state.

Therefore, although the cooling device and the thermostat are installed and used in the car, the small passenger car, which is not a large passenger car, has no space for installing such a separate cooling device and the thermostat, and the burden of installing an expensive device is great. Refrigerants such as freon used in the cooling device has a number of problems, such as being pointed out as a major pollutant to the environment.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks, and to provide two separate refrigerating and insulating spaces by using a thermoelectric element to perform the refrigeration and heat insulation of the object and at the same time by using a heater. In addition, it can be used for both cold and hot, and does not use refrigerant gas such as environmental pollutant that causes pollution.

In this manner, the cold and cold storage can be used not only in automobiles but also indoors in homes and factories. Of course, in order to use a regular AC power supply at home or a factory, a rectifier or an adapter that converts AC into a DC power supply must be additionally used. Moreover, although the present invention is not shown, it is also possible to set a temperature and an operating time by installing an operation panel on the surface of the outer cylinder 10.

In addition, a heat dissipation fan 14 is installed in the outer cylinder 10. The heat dissipation fan 14 allows the outside air to flow to discharge the heat discharged from the internal thermoelectric element 40. The heat dissipation hole 15 for cooling the hole is drilled up and down. Inside the outer cylinder 10 is equipped with a cold inner cylinder 20 to be cooled by the thermoelectric element 40 and the heat insulating inner cylinder 30 heated by the heat transfer heater 50, each of the inner cylinders (20, 30) The cover 60 which can open and close the opened upper part of the outer cylinder 10 is provided in the upper part. The cover 60 is rotatably fixed to the side end of the outer cylinder 10 corresponding thereto with a hinge 61 on one side to open or close the top opening of the outer cylinder 10. Of course, the cover 60 may be composed of a single plate body, but as shown in Figure 2 as two plate bodies (62, 63) to open and close the cold inner cylinder 20 and the thermal insulation inner cylinder 30, respectively. The first and second hinges 61 and 61a are attached to both end sides of the first plate body 62 for opening and closing the thermal insulation inner cylinder 30 and the second plate body 63 for opening and closing the cold inner cylinder 20. Each can turn to the outside to be opened and closed individually. On the other hand, a hinge is attached to the joint portion of the first and second plate bodies 62.63 to allow the second plate body 63 to pivot on the first plate body 62 and to hinge at the side end of the first plate body 62. By attaching (61) and engaging with the outer cylinder 10, once turning the second plate body 63 in the first plate body 62 to open and close only the cold or hot inner cylinder 20, or the cold and hot inner cylinder 20 and the warm inner cylinder 30 In order to open and close all of them, the second plate body 63 is completely lifted up so that the second plate body 63 is pivoted on the first plate body 62, and the first plate body 62 is also turned on the outer cylinder 10 to be cooled. ) And the openings 21 and 31 of the inner container 30 may be opened. Of course, the cover 60 is provided with a locking means (not shown) to maintain a locked state so as not to open when there is no user's operation in the outer cylinder (10).

The thermoelectric element 40 is in contact with the outer surface portion of the aforementioned cold and hot inner cylinder 20. When the thermoelectric element 40 is applied with power in a state where two kinds of metals are bonded to both sides with a conductor composed of an anode body and a cathode body interposed therebetween, the inner metal body is cooled while absorbing heat and the outer metal body In Peltier (heat) is accompanied by the action, it is possible to switch the heat and cold air in the metal body on the outside and the inner side by changing the flow direction of the current. Therefore, the thermoelectric element 40 attached to this cold and hot inner cylinder 20 can also be used by switching the function of a refrigerator and the function of a refrigerator by the operation which changes the direction of an electric current. The coolant 41 is interposed between the thermoelectric element 40 and the cold inner cylinder 20 to transfer the cold air of the thermoelectric element 40 to the cold inner cylinder 20. In addition, a heat absorbing material 42 is attached to the outside of the thermoelectric element 40 to absorb heat and release it to the outside. At this time, in order to help heat dissipation, a cooling fan 14 is installed in the outer cylinder 10 adjacent thereto to forcibly discharge heat to the outside through the heat dissipation hole 15. On the other hand, as shown in Figure 2 by installing the circulation fan 70 inside the cold and hot inner cylinder 20 can increase the cooling effect.

On the other hand, the heat transfer heater 50 is installed on the outer surface portion of the inner cylinder 30 to heat the inner cylinder 30 in accordance with the electricity supply to increase the temperature inside to warm the contents. At this time, in order to prevent the thermal insulation cylinder 30 from overheating, the thermal insulation cylinder 30 is attached with a temperature detector 80 for sensing a temperature. The heat transfer heater 50 and the temperature detector 80 is preferably installed at the bottom of the heat insulating inner cylinder (30).

You must do it. Therefore, the cold and hot inner cylinder 20 and the warm and cold inner cylinder 30 accommodated in the outer cylinder 10 are spaced apart from each other by a predetermined interval, and the heat insulating material 16 is filling therebetween. Styrofoam and urethane are used as the heat shield 16.

3 is a block diagram illustrating an electrical control flow of the apparatus, and the electrical control and flow of the apparatus will be described in detail with reference to FIG. 3.

In order to use the refrigeration function, the thermoelectric element 40 is operated by turning on the refrigerating switch 11 in a state in which a DC power source such as a car is supplied (for example, a cigarette jack is inserted into a receptacle of a car). do. Then, the aforementioned cold and hot inner cylinder is cooled to become a refrigerator. At this time, the freezing time / temperature compensation controller 90 stops the operation of the thermoelectric element 40 when the set time or temperature is maintained to maintain a constant temperature of the cold inner cylinder. Of course, when the internal temperature rises, the thermoelectric element 40 is operated again to lower the temperature.

On the other hand, in order to use the warming function, the thermal switch 11a is turned on as in the refrigerating function. Accordingly, the heat transfer heater 50 is operated so that the inner heat insulating cylinder is heated, and the internal temperature thereof is raised to become a warm storage. At this time, the warming time / temperature compensation controller 100 maintains a constant warming temperature by stopping the operation of the heat transfer heater 50 when the set warming time or the warming temperature is reached.

Now, with reference to the above-mentioned conductive surface will be described in detail how to use the cold storage.

In order to keep the cold drink or water and hot soup in the house as it is to go outside by car, the food to be eaten cold in the cold and hot buckets (20) of the cold and cold store and the food to eat hot in the inner container (30) And close the cover (60). Then, the cigar jack, which is the power supply terminal () of the cold storage, is inserted into the cigar jack receptacle of the vehicle, and the refrigerating switch 11 and the thermal switch 11a are turned on. Then, the thermoelectric element 40 and the heat transfer heater 50 are operated so that the cold inner cylinder 20 is cooled and the warm inner cylinder 30 is heated to operate as a refrigerator and a warmer respectively. If you go to the destination in that state to open the cover 60 and take out the food stored in the cold and cold inner container 20 and the warm inner container 30, respectively, the cold beverage can be eaten warmer and hot food as it is cooked at home.

Of course, if you do not need the cold food, such as winter, only to keep hot food, if you change the current direction of the power applied to the thermoelectric element 40 in the metal surface of the thermoelectric element 40 in contact with the cold and hot inner tube 20 Heat is released to be delivered to the cold and cold inner cylinder (20). Therefore, the cold and warm inner cylinder 20 becomes a thermal insulation container and functions as a warmer with the warmth inner cylinder 30. Accordingly, many foods are kept warm so that they can be eaten when necessary. Of course, the cold inner cylinder 20 or the warm inner cylinder 30 can be used to operate only the desired inner cylinder by turning on / off each of the refrigerating switch 11 and the warm switch 11a individually. As a result, when the contents to be stored are small or when only one of the functions of the cold and hot storage is used, the power consumption can be reduced to save energy.

As described above, the pollution-free cold storage according to the present invention has the effect that can be used for both cold and hot at the same time having two separate refrigerated space and the warming space. In particular, since it uses a thermoelectric element for cooling and does not use refrigerant gas such as freon that causes pollution, it is not only environmentally friendly, but also thermoelectric element can be used in a space to be quiet with no noise and vibration. According to this, since the direction of absorption and heat generation can be switched, the refrigerating and heating functions can be used simultaneously. Accordingly, the cold and warm water can be cooled / warmed by operating the cold / warm storage in the car when moving to a car, and thus, a cold drink or a hot drink can be selected at any time when traveling. In addition, the device has a feature that it can be easily used indoors, such as homes or factories by using additional devices such as a rectifier or an adapter for direct current conversion that can be easily purchased anywhere. In addition, the temperature detector detects the temperature of the inner barrel and stops the operation when the temperature rises above the appropriate temperature, and operates again when the temperature falls below the set temperature, thereby reducing the power consumption.
