Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distilled water production pot, and more particularly to a domestic distilled water production pot using a Peltier element as a cooling means.

[0002]

2. Description of the Related Art In recent years, there has been a demand for removing tasty smells of tap water, small amounts of bacteria contained in tap water, impurities such as iron rust, and harmful substances such as trihalomethane to obtain tasty and safe water. It is rising.

To meet such demands, various water purifiers and water purifiers have been developed so far. However, in these water purifiers and water purifiers, most of the methods of removing impurities such as odors and bacteria by adsorption or filtration using filter media such as filters and activated carbon are used. By improving the performance of the filter medium, the removal rate of the above impurities and the like is increased, but harmful substances having a small molecular weight such as trihalomethane cannot be removed, and there is a problem in safety. Further, in this system, it is necessary to replace the filter medium quite frequently in order to prevent the deterioration of the performance due to the clogging of the filter medium, the propagation of bacteria, etc., and there is a problem in the labor and cost of maintenance.

For this reason, a distilled water maker which has been used only in a limited field up to now and which uses a distillation system capable of obtaining highly pure water has been developed for household use, and trihalomethane contained in tap water has been developed. Attempts have been made to remove almost 100% of harmful substances such as the above and impurities such as bacteria.

As such a domestic distilled water producing apparatus,
For example, water is boiled in the jar part in the same way as an electric jar pot that is usually used for boiling water and can keep warm, and the steam generated in the jar is heated by a heat exchanger attached to the lid part. A pot type and the like that obtains distilled water by cooling and condensing are known. In such a distilled water production pot, the cooling means of the heat exchanger is air-cooled, so that the surface area of the heat exchanger is large,
The cooling efficiency was increased by circulating air using a fan or the like. However, in the above cooling means, if the surface area of the heat exchanger is made large, the heat exchanger itself becomes large, and even if a considerable surface area is taken, it takes time to cool it. Then there were problems such as noise.

On the other hand, the cooling means using the Peltier element is
In recent years, it has attracted attention as an alternative to cooling means using a CFC gas refrigerant, and has already been put to practical use in small refrigerators, portable coolers, and the like. In addition, the development of an electric jar pot for both hot and cold water, which utilizes the property that the same surface can be used for both cooling and heating simply by reversing the direction of the current of the Peltier device, is in progress. However, a distilled water production apparatus using this Peltier element as a cooling means is not known.

[0007]

The present invention has been made from the above viewpoint, and is a domestic pot for producing distilled water provided with a heat exchanger that is compact, does not generate noise, and has a sufficient cooling capacity. The challenge is to provide.

[0008]

In order to solve the above problems, the present inventor has repeatedly studied a heat exchanger for cooling steam in a distilled water production pot, and as a result, has found that a Peltier element is used as a cooling means. By using the heat exchanger, the heat exchanger is compact, does not generate noise, and has sufficient cooling capacity.

That is, the present invention provides a water container having a heating means for heating water in the container, a conduit for introducing water vapor generated by heating the water in the water container, and a conduit from the water container. A heat exchanger having a cooling means for cooling water vapor introduced therethrough, and a distilled water outlet for taking out distilled water obtained by cooling and condensation in the heat exchanger, wherein the cooling means has a Peltier element It is a water production pot.

The present invention will be described in detail below. The distilled water production pot of the present invention comprises a water container having a heating means for heating the water in the container, a conduit for introducing water vapor generated by heating the water in the water container, and a conduit from the water container. A heat exchanger having a cooling means for cooling the water vapor introduced through the water, a distilled water outlet for taking out distilled water obtained by cooling and condensing in the heat exchanger, and the cooling means having a Peltier element. It is a thing.

The water container of the distilled water producing pot of the present invention is not particularly limited as long as it has a heating means capable of heating and evaporating the contained water, but a preferable structure is an inner container and an outer container. A heating means is installed between the inner container and the outer container, and a heat insulating material such as expanded polystyrene resin, polyurethane foam, expanded ceramics, or glass fiber coated with aluminum in the gap between the inner container and the outer container. Is filled with
An example is a structure in which the inner container is removable.

Both the inner container and the outer container constituting the water container are made of a material having heat resistance enough to withstand the heating by the heating means, and the inner container is a material in which the components are not eluted by boiling water. Alternatively, it is necessary to perform a treatment such as forming a coating film on the surface of the inner container, which is in contact with water, with a material from which components are not eluted by boiling water. For example, when the inner container is made of stainless steel or the like whose surface in contact with water is coated with a fluororesin and the outer container is made of resin or the like, a pot that satisfies the above conditions and looks good can be obtained. Furthermore, "-MAXF
It is preferable to show a guideline for the maximum amount of water to be stored by displaying "ILL-", "-Cocomade-", or the like.

The heating means is not particularly limited as long as it has the ability to heat and evaporate the water contained in the container.
A heating means similar to a normal kettle pot, for example, a heating wire, a microwave heating means, or the like can be used. Although it is the installation position of the heating means, if it is installed at the bottom of the water container, it becomes possible to efficiently heat the water as the content.

In the distilled water production pot of the present invention, it is preferable to provide a degassing valve in the conduit for guiding the steam generated in the water storage container to the heat exchanger. This valve has a structure in which the gas in the container is opened for a certain period of time after the water starts to be heated, gas other than water generated immediately after heating is discharged to the outside of the container, and then closed.

Further, it is preferable that the distilled water producing pot of the present invention is provided with a mechanism for opening it when the pressure in the pot becomes equal to or higher than the pressure which is a safety problem. As such a mechanism, a safety valve with a structure that opens when the pressure that poses a safety problem is released and allows the steam to escape to the outside of the pot is provided on the surface where the pressure of the steam is applied, or the water container is covered. If it has a structure that has a structure that opens this cover when a pressure that is a safety problem or more is applied, for example, put the lid on the water container and seal it only by its own weight, and press the pressure more than the weight of the lid. Examples of such a structure include a structure in which the lid can be removed when exposed to scratches.

When a safety valve is used as such a safety mechanism against the pressure of steam, it is also possible to design the gas vent valve with the function of this safety valve. In other words, the gas vent valve may be designed to be opened for a certain period of time after the start of heating of the content water, and then closed to open when the pressure in the pot becomes equal to or higher than the pressure that poses a safety problem. .

The heat exchanger of the distilled water production pot of the present invention comprises:
There is no particular limitation except that a Peltier element is used as the cooling means, but it is preferable to further combine this with a cooling fin, whereby cooling condensation of water vapor can be performed more efficiently. In the heat exchanger used in the present invention, it is preferable that the Peltier element is installed in a cooling part of the heat exchanger and a cooling fin is installed outside the cooling part. The mechanism of the heat exchanger may be a mechanism that does not use a refrigerant at all, or a mechanism that uses water or the like as a refrigerant.

The heat exchanger has heat resistance enough to withstand steam, and the inside is coated with a material that does not contain components that are eluted by steam, or the material of the heat exchanger itself does not contain components that are eluted by steam. It is required to be a material. Moreover, it is preferable that the cooling part and the cooling fins of the heat exchanger are formed of a material having good thermal conductivity. The Peltier element installed in the heat exchanger must be selected with due consideration of the required cooling capacity. If the capacity is larger than necessary, it is economically disadvantageous, and if the capacity is insufficient, the cooling time becomes very long, which is not preferable.

In the heat exchanger, the steam is cooled and condensed into distilled water, which is supplied from a distilled water outlet connected to the heat exchanger via a conduit for guiding the distilled water. In order to maintain the purity of the obtained distilled water, a material that does not contain a component that dissolves in water is used for the conduit for guiding the distilled water, and it is preferable that the conduit is further subjected to an antibacterial treatment or the like.

The distilled water production pot of the present invention may be provided with a vertically movable bottle adapter for holding a container for storing distilled water taken out of the pot. When the container used to store the distilled water is small, this adapter may be moved upward so that the mouth of the container is located near the distilled water outlet of the pot. In addition, this bottle adapter is provided with a function for displaying the amount of distilled water stored in the container and a button for displaying the volume in several stages, for example, 500 mL, 1 L, 1.5 L, 2 L, etc. When setting a bottle for storing distilled water, use a button that matches the capacity of the bottle (for example, 50
When 0 mL) is pressed, it is possible to automatically switch off when the set volume (500 mL) of distilled water is stored in the bottle and to have a function of preventing the distilled water from overflowing from the bottle.

In the distilled water producing pot of the present invention, the water container has a lid which is openably and closably connected by a hinge mechanism and is detachably connected, and a heat exchanger is installed inside the lid. However, it is also possible to use it as a water heating jar pot by attaching a lid having a supply means for supplying hot water in the container to the outside of the container instead of the lid having the heat exchanger. When the distilled water production pot is used as a boiling water jar pot by replacing the pot upper part,
By using a switching switch, etc., the capacity of the heating means of the water storage container when it is turned into a boiling water jar pot automatically switches from the output until the water boil to the output required for heat retention once it has boiled. It should be possible to set it.

[0022]

In the distilled water production pot of the present invention, the water previously put in the container is heated and evaporated by the heating means, and the generated water vapor is guided to the heat exchanger through the conduit, where the cooling means has the Peltier element. It is cooled and condensed to obtain distilled water, and the obtained distilled water is supplied to the outside of the pot from the distilled water take-out port from the heat exchanger via the conduit. In the present invention, by using the one having a Peltier element as the cooling means of the distilled water production pot as described above, the heat exchanger,
It has become possible to make it compact as a whole, generate no noise, and have a sufficient cooling capacity.

A preferred structure of the water container of the distilled water production pot of the present invention comprises an inner container and an outer container,
A heating means is installed between the inner container and the outer container, and
A structure in which a gap between the inner container and the outer container is filled with a heat insulating material so that the inner container is detachable can be mentioned. In a distilled water production pot, the amount of heat required to boil and evaporate a relatively large amount of water is quite large, and the inclusion of the above-mentioned heat insulating material prevents the heat from escaping outside the container and lowering the thermal efficiency. It is also possible to eliminate the risk caused by heat generation outside the container. Further, by making the inner container detachable, the work of storing water in the container and the work of cleaning dirt and the like adhering to the inner surface of the container can be simplified.

Further, in the distilled water production pot of the present invention, the conduit for guiding the steam generated in the water storage container to the heat exchanger is opened for a certain period of time after the water in the container starts to be heated and immediately after the heating. It is preferable to provide a gas vent valve having a structure in which the generated gas other than water is discharged to the outside of the container and then closed.

By opening this degassing valve for a certain period of time in a relatively early stage from the start of heating before the water boils, substances having a lower boiling point than water, such as trihalomethane, which is a harmful substance contained in tap water, evaporates. It is possible to discharge the generated steam outside the pot. As a result, it is not necessary to distill the tap water to eliminate the dangerous high-concentration trihalomethane aqueous solution that is initially obtained, and it is possible to obtain distilled water with high purity from the first drop. Also, after the initial stage of distillation, if this gas vent valve is designed to function as a safety valve that opens above the pressure that poses a safety problem, even if the pressure inside the pot becomes abnormally high, safety will be improved. There is no problem.
