Abstract

PURPOSE: To efficiently cool/heat liquid and air by circulating them by vertically forming a projection or recessed part having a flat part over a full height on the side surface of a vessel made of metal, etc., and closely fixing the mechanism of a Peltier element. CONSTITUTION: A vessel 1 is cylindrically formed and on its outer side surface, a flat protruding part 2 having the width of a pair of Peltier elements is formed over the full length of the vessel in the state of facing at 180 deg.. On the outer side surface of the protruding part 2, a Peltier element mechanism 2 is closely fixed on the vessel 1. Further, a heat absorbing/radiating instrument 5 having a heat absorbing/radiating fin 4 is closely fixed on the outer surface of the Peltier element mechanism 3 and heat is exchanged with the outside by pumping the heat of liquid or gas in an internal part 6 of the vessel 1. When filling the vessel 1 with water and cooling it, first of all, the contact part of the vessel 1 is cooled by the Peltier mechanism 3, the vessel 1 is cooled with spreading on its surface by successive heat conduction and since the inside water is simultaneously cooled as well, the spread of heat conduction is not enlarged so much.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tabletop water heater and a water purifier used for cooling and heating ordinary water, tap water, mineral water, alkaline ionized water, etc., or a water purifier directly connected to water. .

[0002]

2. Description of the Related Art For the purpose of recent deterioration of water quality and promotion of health, households who do not drink tap water as it is, but use water from a water purifier, alkaline ionized water generator, commercially available mineral water, oolong tea, etc. The rate is overwhelming. However, at homes, offices, factories, etc., there is no space to cool a large amount of tap water, purified water, mineral water, etc. in a refrigerator, so juices, colas, and other sugar-rich items are purchased from vending machines. There are many things to do and there is inconvenience when eating.

[0003]

Therefore, the applicant of the present invention has proposed that a Peltier element-equipped cold / hot water device is installed outside a tabletop pot, a mineral water generator, a water purifier, an alkaline ionized water generator, etc., which is formed of a good conductor of heat. Face-to-face contact, the container absorbs heat and acts as a heating element.The inside of the container is left with a band-shaped spherical heat part at the top of the liquid contact, and a heat-insulating film such as fluorine resin is applied. We proposed a chiller / heater that can naturally convection and can cool efficiently. However, the efficiency of heat conduction was still poor, and there was a problem in establishing a water heater.

[0004]

SUMMARY OF THE INVENTION Therefore, according to the present invention, a Peltier element is provided on the outer surface of a table-top pot, a mineral water generator, a water purifier, an alkaline ionized water generator, etc., which is formed by a Peltier element as a cooling / heating device. By arranging the strips vertically, the cooling liquid and air are lowered by cooling not only the lower part but also the middle part and the uppermost part during cooling. The inside can be continuously convected. Further, the present invention provides a chiller-heater capable of improving efficiency by heating the whole from the bottom to the top evenly during heating.

Another object of the present invention is to prevent the flow of air from a forced air cooling fan separately installed on the upper head and the lower bottom of the container on the outer surface of the Peltier element from outside the container. By installing multiple vertical fins on the side,
Heat insulation is applied to the container excluding the part that is not related to heat dissipation,
Further, by providing a decorative cover around the outer periphery thereof and forming a space formed by the fins and the decorative cover as an air duct from a fan, it is possible to provide a water heater having a small diameter.

Still another object of the present invention is to provide a water cooler / heater capable of keeping the overall diameter small by adding a suction / radiating device to the shape of the container.

[0007]

[Function] That is, a container is made of copper, aluminum, stainless steel or the like having good heat conductivity, and a flat portion protruding in a strip shape is formed on the outside of the side surface, and the mechanism of the Peltier element is closely attached and fixed to the Peltier element. A heat dissipation and heat absorption tool having a shape conforming to the outer surface of the container is installed on the outside of the mechanism, and the whole container is absorbed and used as a heat dissipation device.Furthermore, a forced air cooling fan installed on the head or lower part of the container The gist is that it is configured with a duct that guides the flow of air and that it can be cooled and heated efficiently.

[0008]

EXAMPLES The chiller-heater according to the present invention will be described by way of examples. FIG. 1 is a cross-sectional view of a tabletop type pot of the embodiment, in which the container 1 is made of 316 stainless steel having a thin wall thickness of 0.2 mm and having high corrosion resistance, because heat conduction is taken into consideration and pressure is not applied. On the outer surface of the container, a flat protrusion 2 having a width of a pair of Peltier elements was formed at the height of the container so as to be opposed to 180 degrees. The Peltier element mechanism 3 is closely fixed to the container 1 on the outer side surface of the protruding portion, and further,
The Peltier device mechanism 3 has a structure in which suction and heat radiation fins 4 are suction-held on the outer surface of the Peltier device mechanism 3, and a heat-dissipating tool 5 is closely fixed, and the heat of the liquid or gas inside the container 1 is pumped to exchange heat with the outside. FIG. 2 is a vertical cross-sectional view of an example in which the Peltier element mechanism 3 is installed only on one side. The protrusion 2 is formed in the entire length of the container 1, and the Peltier element mechanism 3 is similarly fixed to the protrusion. The liquid and gas in the container 1 can be efficiently cooled and heated. The forced air cooling fan 7 is for efficiently absorbing and radiating the heat of pumping of the Peltier device mechanism 3, and is installed in the lower portion of the container 1 in the embodiment in order to suppress the outer shape of the container 1 from spreading. However, the air flow may be provided on the head so that the air flows from the upper part to the lower part. The duct cover 8 forms a plurality of duct-shaped chambers in which air flows, which is formed in the groove 9 of the fin 4, and allows the air of the fan 7 to flow therethrough to efficiently perform heat exchange through the fin 4. Can be done. The heat insulating portion 10 surrounding the entire container 1 is a Peltier device mechanism 3
In order to prevent the heat exchange rate from decreasing, a resin foam having a high heat insulation effect was used.

Next, an example of cooling will be described. Assuming that the container 1 of FIG. 2 is filled with water to be cooled, the contact portion of the container 1 is first cooled by the Peltier device mechanism 3, and the container 1 is cooled with a spread on the surface by sequential heat conduction. However, since the water inside is also cooled at the same time, the spread of heat transfer is not so large. Due to the Peltier element mechanism 3, the water in the container 1 is also cooled at the same time, and as the density increases, it descends along the inner surface of the container 1 and pushes up warm water in the lower part continuously, causing convection and generating a uniform temperature. You can expect a descent. It is natural that the same Peltier element mechanism 3 can be expected to have the same convection descent even if the number of pairs of Peltier element mechanisms 3 faces each other is increased, and the cooling time can be shortened by the increased number. In addition, the Peltier device mechanism 3 can be expected to have the same effect even if the Peltier device mechanism 3 is installed in the upper and lower parts by removing the middle part. In the case of only the upper part, not only the cooling efficiency is poor, but also the temperature rises only in the upper part during heating in which the current direction is reversed, and convection does not occur, which is a serious drawback. Peltier element assembly 3 during heating
With respect to the arrangement of the above, there is no problem because the one installed at the lower part in the embodiment assuming cooling time performs heating, raises warm water, and lowers intermediate cold water. of course,
It was found that the problem does not occur even if it is installed on the entire surface of the protrusion.

[0010]

As described above, according to the present invention, it is necessary to form a protrusion or a recess having a flat portion vertically to the side surface of a container made of metal or the like so that the mechanism of the Peltier element is closely attached and fixed. Therefore, during cooling and heating,
It has the practical benefit of efficiently convection of liquid and air and efficient cooling and heating.

Further, according to the present invention, the suction and heat dissipation device having a plurality of fins formed in the vertical direction is closely fixed to the Peltier element mechanism, and the groove portion of the fin is made into a duct by the decorative cover, thereby making the container head. With the air of the forced air cooling fan installed at the part or bottom, it has the practical benefit of efficiently absorbing and radiating heat.

Furthermore, according to the present invention, by separating the forced air cooling fan into the head portion or the lower portion,
It has the practical benefit of being able to reduce the diameter of the container.
