In addition, in the electric refrigerator as described above, freon gas or the like used as a refrigerant causes environmental pollution of the earth by destroying the ozone layer of the earth, and therefore, a new cooling method is required to suppress the tendency of using it all over the world.
In view of the above, a small refrigerator used in an automobile or a motorcycle includes a thermoelectric element coupled to an inner case through a predetermined coupling means on a rear surface of the refrigerator, an aluminum block coupled to one side of the thermoelectric element, a cold exchanger in contact with one side of the aluminum block and positioned between the inner case and a heat insulating wall of the refrigerator to perform heat exchange with the inside of the refrigerator, thereby performing a cooling function, and a heat exchanger coupled to the other side of the thermoelectric element and emitting heat generated from the thermoelectric element to the outside.
However, the conventional small refrigerator has a disadvantage in that since it is fixed to a moving tool such as an automobile or a motorcycle, the small refrigerator can be used only in the moving tool, and when a trouble occurs, a troublesome operation of separating a predetermined refrigerator from the moving tool is required.

Detailed Description
The cooling and heating cabinet according to an embodiment of the present invention uses a thermoelectric element.
The thermoelectric element uses the Peltier effect, and when a direct current is applied, one end generates heat and the other end absorbs heat, and has a simple structure and high reliability, and no mechanical operation parts are provided, so that noise and vibration do not occur.
When power is applied to such a thermoelectric element, one side of the thermoelectric element generates heat and the other side absorbs heat. By utilizing such characteristics, the inside of the cooling and heating cabinet can be kept at a predetermined temperature.
The related art has a problem in that it is difficult to realize a small-sized refrigerator due to a large structure for realizing a freezing cycle, and the related refrigerator has a problem in that it is difficult to heat and maintain the inside to a specific temperature while maintaining the inside at a low temperature. In addition, recently, vehicles as moving means are widely used, but such vehicles have a problem in that a cooling and heating cabinet capable of drinking cold or hot drinks has not been developed.
In order to solve the problems, the invention can realize the miniaturization of the cooling and heating cabinet by using the thermoelectric element with simple structure, is easy to maintain specific temperature and is also easy to be installed on vehicles.
As shown in fig. 1, the cooling and heating cabinet 100 of the present invention is installed in a vehicle 15. In this case, as shown in the drawings, the cooling and heating cabinet 100 may be disposed at the front side of the vehicle 15, but the present invention is not limited thereto.
In addition, the vehicle 15 may use a motorcycle as shown in fig. 1, and the present invention is not limited thereto.
The cooling and heating cabinet 100 includes a main body 110 having a cooling and heating space 113 formed therein, and a thermoelectric element unit 200 positioned at a lower side of the main body 110. The main body 110 includes a case 111 having a cooling and heating space 113 formed therein and an open/close cover 112 for opening and closing an open upper portion of the case 111.
As shown in fig. 7 to 9, the opening/closing cover 112 is rotatably provided at one side of the upper portion of the housing 111, and can open and close the upper portion of the housing 111. A known hinge member 118 may be included for this purpose.

Wherein the middle of the support plate 111-7 is opened so as to be able to connect the thermoelectric element 210 and the heat sink 230 to each other.
The bottom surface of the lower side portion 111-4 is formed with a receiving wall 111-8 in a vertical direction to surround the circumference of the heat dissipation fan 240, so that the heat dissipation fan 240 can be stably disposed.
The thermoelectric element 210 may be directly provided on the heat sink 230, or may be provided through an elastic mounting portion 220 as shown in fig. 2. The mounting portion 220 is disposed on the heat sink 230 and has a shape with an open center. After the mounting portion 220 is disposed on the heat sink 230, the thermoelectric element 210 is mounted on the open portion of the mounting portion 220. A protrusion portion 210-1 is formed at an outer side of the thermoelectric element 210, and a groove portion 220-1 is formed at an open portion of the mounting portion 220 so as to be coupled male and female.

The supporting members 302 are bent and protruded from left and right ends of the fixing plate 301, respectively. An insertion space 303 into which the body 110 can be inserted is formed between the support members 302. At this time, the support members 302 are formed to be spaced apart from each other by a distance corresponding to the left-right width of the housing 111. The ends of the support member 302 are bent in a direction adjacent to each other, thereby clamping the body 110 inserted into the insertion space 303.
Preferably, the body 110 is inserted into the insertion space 303 between the support members 302 from the upper side of the support members 302 downward.
The handle part 400 comprises a slide bar 401, an upper end part 402 and a lower end part 403.

The second sliding groove 523 extends downward by a predetermined length at a lower end of the first sliding groove 522, and is bent to be adjacent to the coupling protrusion 510. At this time, when the front surface of the fixed plate 301 is formed with the coupling groove 511 instead of the coupling protrusion 510, it is preferable that the second sliding groove 523 curvedly extends adjacent to the coupling groove 511.
On the other hand, although the illustrated example shows a configuration in which the projecting protrusion 521 is formed on the slider 401 and the first and second sliding grooves 522 and 523 are formed on the support member 302, the present invention is not limited to the illustrated example, and a plurality of projecting protrusions 521 may be formed on the inner surfaces of a plurality of support members 302, and a first and second sliding grooves 522 and 523 may be formed on the slider 401.
At this time, it is preferable that the first sliding groove 522 is extended upward by a predetermined length from the lower end portion of the slide bar 401, the second sliding groove 523 is extended to the upper end portion of the first sliding groove 522, and is formed farther from the coupling protrusion 510 or the coupling groove 511 formed at the coupling bracket 300 as the distance from the first sliding groove 522 is farther.
On the other hand, a detailed description of a method of using the cooling/heating cabinet 100 for a vehicle according to the present invention configured as described above is as follows.
First, when the main body 110 is fixed to the moving tool 15, the main body 110 is inserted into the insertion space 303 of the coupling bracket 300. At this time, the main body 110 is inserted into the coupling bracket 300 so that the plurality of protruding protrusions 521 can be inserted into the plurality of first sliding grooves 522 formed in the coupling bracket 300.
When the upper portion of the handle member 400 is pressed, the handle member 400 slides downward with respect to the main body 110. At this time, the protrusion 521 formed on the handle member 400 moves from the first sliding groove 522 to the second sliding groove 523, and the upper end member 402 of the handle member 400 approaches the upper surface of the main body 110, thereby moving the main body 110 together with the handle member 400.
When the main body 110 is closely attached to the front surface of the fixed plate 301 along the rear surface of the second sliding groove 523 along with the movement of the handle member 400, the coupling protrusion 510 formed on the front surface of the fixed plate 301 is inserted into the coupling groove 511 formed on the rear surface of the main body 110, and the main body 110 is fixed to the coupling bracket 300.
On the other hand, when separating the body 110 from the coupling bracket 300, the user holds the upper end portion of the handle member 400 and then slides the handle member 400 upward with respect to the body 110.
At this time, the protrusion 521 moves from the second slide groove 523 to the first slide groove 522, and the body 110 is spaced from the front surface of the fixed plate 301 according to the movement of the protrusion, thereby separating the coupling protrusion 510 from the coupling groove 511.
On the other hand, the lower portion of the main body 110 is supported by the lower end part 403 of the handle part 400, so that the main body 110 moves together with the handle part 400. The user separates the main body 110 from the coupling bracket 300 in a state of holding the upper end member 402. At this time, a predetermined space is formed between the upper surface of the body 110 and the upper end member 402 of the handle member 400 so that the user can easily grip the upper end member 402.
The cooling and heating cabinet 100 for a vehicle according to the present invention configured as described above can be easily fixed to a moving means 15 such as a vehicle or released from a fixed state by the fixing portion 500, and thus has an advantage that it can be detached from the moving means 15 according to a user's need.
A method of supplying power to a vehicle including the cooling and heating equipment using a thermoelectric element according to the present invention will be described below.
First, the thermoelectric element 210 is supplied with power by the control part CON. At this time, the polarity of the supplied power is controlled, thereby adjusting the temperature of the cooling and heating space 113.
After the cooling and heating space 113 is cooled by the thermoelectric element unit 200 so that the cooling and heating space 113 reaches a certain temperature, the power supply to the thermoelectric element unit 200 is turned off by the control part CON. However, the heat dissipation fan 240 is operated for a predetermined time to discharge the generated heat.
On the other hand, the vehicle 15 is provided with a generator (not shown) and an auxiliary battery 19, and the auxiliary battery 19 can be charged by the generator or the thermoelectric element unit 200 can be operated by the generator.
In other words, the vehicle 15 is provided with a generator or an auxiliary battery on one side, and power is supplied to the thermoelectric element unit 200 through the generator, or power is supplied to the thermoelectric element unit 200 through the auxiliary battery, or power is supplied to the thermoelectric element unit 200 through an external power source.
While the embodiments of the present invention have been described with reference to the drawings of the present invention, it will be understood by those skilled in the art to which the present invention pertains that other embodiments may be implemented without changing the technical spirit or essential features of the present invention.
It is therefore to be understood that the foregoing embodiments are illustrative and not restrictive in all respects, the scope of the invention being indicated by the appended claims, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
