Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an electronic jar that uses a Peltier element to cool and keep cold and heat and keep warm.

(Prior art) Conventional general magic bottles use a double glass cylinder with a vacuum insulation layer and a mercury film to reflect heat and insulate it, but glass is not only easily damaged. , there is no mechanism for heating or cooling the contents. Jars equipped with a heating mechanism have been proposed in the past, but in this case, there was no cooling function.

(Problems to be solved by the invention) In view of the fact that conventional jars only have the function of heating (heat retention) or cold retention, this invention solves the problem by simultaneously exhibiting the functions of heating heat retention and cooling cold retention. This is the problem we are trying to solve.

(Means for Solving the Problem) Therefore, the present invention consists of a pair of outer cylinders that are made of a metal with good thermal conductivity, each provided with a water inlet, and that stores the injected water. Inserting and fixing the inner cylinders, arranging Peltier elements so that both joint parts are in contact with the inner cylinders, fixing fins on the outer surfaces of each of the pair of inner cylinders, and blowing outside air onto the fins. A fan is provided in the outer cylinder, and a damper is provided to switch the flow path so that the outside air flows to each of the fins, and the space between the inner and outer cylinders excluding the fin and fan parts and around the Peltier element are insulated. The outer cylinder is filled with a material and provided with an inlet and an outlet for the outside air, and this is used as a means to solve the problem.

(Function) When water is poured into a pair of inner cylinders through their respective injection ports and a current is passed through the Peltier element, one inner cylinder side is cooled and the other inner cylinder side is heated. In this case, if you switch the damper so that outside air is sent from the fan to the fan on the heated side, the temperature of the water in the inner cylinder on the same side will not rise that much, and the water in the inner cylinder on the cooling side will become cold water. becomes. Also, if you switch the damper in the opposite direction so that outside air is sent from the fan to the fan on the side being cooled,
Since it is difficult for the container on the side to be heated to radiate heat, the water temperature in the inner cylinder on the same side will be higher than in the former case. However, on the cooling side, the water temperature does not drop that much.

(Example) The present invention will be explained below based on the embodiments shown in the drawings.

This invention uses a Peltier element, but first, to explain the Peltier effect, a closed circuit made of two substances is created by combining two different metals and semiconductors, and each part of the closed circuit is kept at a constant temperature. When a current is passed while maintaining the temperature, heat other than Joule heat is generated at one side of the two junctions, and absorption is observed at the other side. This phenomenon is called the Peltier effect.

Now, the drawing shows one embodiment of the electronic jar of the present invention, 1 is an outer cylinder, and has a pair of injection ports 2, 2a.
Each injection port 2, 2a is provided with a plug 3, 3a. Reference numerals 4 and 4a denote a pair of inner cylinders made of a metal such as aluminum having good thermal conductivity, and inserted and fixed in series in the outer cylinder 1, and are connected to the injection ports 2 and 2, respectively.
Store the water injected from a. Note that the inner cylinders may not be arranged in series with their axes aligned as shown in the drawings, but may be arranged in parallel in parallel.

Reference numeral 5 denotes a Peltier element, which is fixed to the bottom of each of the inner tubes 4, 4a with its joint portions on both sides in contact with each other. 6,
Reference numerals 6a denote fins attached to the outer surfaces of the inner cylinders 4 and 4a, respectively, and the fins 6 and 6a are supplied with outside air taken in from the intake port 8 provided in the outer cylinder 1 by the fan 7 by switching the damper 9. The outside air is actively cooled down, and this outside air is exhausted from the exhaust port 10. 12, 12 are lids that alternately open and close the left and right discharge ports 10 in conjunction with switching of the damper 9. Reference numeral 11 denotes a heat insulating material filled in the space between the inner and outer cylinders 1, 4, 4a, excluding the fins 6, 6a and fan 7, and around the Peltier element 5, which is obtained by injecting and foaming urethane or the like. 11 is an outlet for outside air.

Although the fins are arranged perpendicularly to the air flow in the drawing for clarity, they are actually arranged parallel to the air flow for rectification. Although not shown, electric wires, lead wires, switches, etc. for supplying current to the fan motor and Peltier element are naturally provided. Furthermore, it may be constructed to be operated by dry batteries, making it convenient to carry.

Next, the operation of the embodiment configured as above will be explained. First, remove the plugs 3 and 3a, and then open the inlet 2,
After injecting water into the inner cylinders 4 and 4a from 2a,
Tighten the stoppers 3 and 3a. Next, when a current is passed through the Peltier element 5, one side of the inner cylinder 4 is cooled, and the other side of the inner cylinder 4a is heated. Here, when the damper 9 is switched and the fan 7 is turned so that outside air hits the heating side fins 6a, the fins 6a are cooled. However, since no significant heat radiation occurs in the fins 6b on the cooling side, cold water can be obtained on the inner cylinder 4 side. Furthermore, when the fan 7 is stopped in this state, the temperature of both the cold water in the inner cylinder 4 and the hot water in the inner cylinder 4a rises to some extent. Furthermore, when the damper 9 is switched and the fan 7 is turned so that the outside air hits the fin 6b on the cooling side, the fin 6b actively exchanges heat, while the fin 6a
Since heat dissipation is not promoted, the water temperature on the inner cylinder 4a side further increases. In addition, a thermostat or the like is provided to prevent the water temperature in the inner cylinder 4 from becoming below a predetermined temperature or the water temperature in the inner cylinder 4a from exceeding a predetermined temperature.
The current may be turned off.

(Effects of the invention) Since the present invention is constructed as explained in detail above, cold water and hot water can be obtained simultaneously in a pair of containers by simply passing a current through the Peltier element, and the hot water side can be obtained at the same time. If the fins are actively cooled, the temperature of the cold water obtained by the inner cylinder on the cold water side will become somewhat lower, and if the fins on the cold water side are further cooled, the temperature of both cold water and hot water will rise, making it hotter. You can get hot water. In addition, the present invention has a simple structure, is convenient to carry, and has the advantage that there is no risk of breakage unlike conventional jars using glass tubes.
