This casing 1 comprises a case body 1a having a housing part inside and a cover 1b fitted to each other. The casing 1 can be baked in shape of a flat-container or else in an optional shape according to use such as cylindrical, rectangular parallelepiped-shape, or spherical container.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is mainly used in households and restaurants to remove impurities contained in tap water and well water by adsorption to remove water and to elute mineral components beneficial to the human body to improve water quality. The present invention relates to a water quality improving device that improves the gloss of cooked rice and improves its taste, especially when used in a rice cooker.

[0002]

2. Description of the Related Art In recent years, the quality of tap water, in particular, tends to deteriorate with the contamination of river water, and a large amount of chlorine and chlorine are used in tap water for sterilization. Therefore,
Various water purifiers for reforming tap water by adsorbing malodorous substances such as chalky and chlorine contained in tap water are commercially available.
As this kind of water purifier, charcoal is used at the time of cooking rice because it is cheaper than other filter media, has a strong adsorption power, and is harmless to the human body. This charcoal water purifier has been evaluated to improve the taste of cooked rice by adsorbing mineral components eluted from charcoal and impurities by pores peculiar to charcoal.

[0003]

However, since this charcoal water purifier uses the charcoal itself as it is, it is fragile and has problems in handling such as being scattered in rice and water, and has a black color. The cleanliness is inferior and the commercial value is lowered. The present invention focuses on the function of charcoal,
It is an object of the present invention to easily improve the quality of tap water as a drink or tap water at the time of cooking rice so as to facilitate handling and to elute minerals useful for the human body.

[0004]

According to the present invention, there is provided a water quality improving device comprising at least one mineral component selected from calcium, potassium and magnesium in a case made of an oxide ceramic having a porosity of 20 to 50%. And charcoal.

[0005] According to this means, when poured into a container or a rice cooker, tap water enters through the pores of the ceramics as a case, and impurities such as calcium and chlorine in the tap water are mixed with the pores of the ceramics and the inside of the case. Is adsorbed by the pores of the coal. Further, a mineral component beneficial to the human body is eluted and dispersed into the container or the device from the case, the charcoal sealed therein and the mineral component-containing powder. Therefore, tap water is easily improved.

In the present invention, the porosity is the porosity (effective porosity) of a so-called open pore communicating with the outside, and the porosity is set to 20 to 50%.
If the porosity is less than 20%, the infiltration of tap water becomes insufficient, and the adsorption performance is reduced. If the porosity exceeds 50%, the encapsulated powder directly flows out, which is not preferable. is there.

[0007] The charcoal of the filling material can be general charcoal obtained by steaming oak, oak, larch, etc., but bincho charcoal or bamboo charcoal is particularly preferable, and can be of any shape such as granular, powdery, lump and granular. Good.

By the way, the oxide ceramics used in the present invention includes alumina (Al ₂ O ₃ ),
Magnesium oxide (MgO), silica (SiO ₂ ), zeolite, or the like can be used, but alumina, which is white and advantageous in terms of adsorptivity and economy, is preferred. In addition, a ceramic porous body can be used instead of the oxide ceramic.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A water quality improvement tool according to an embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the water quality improving device A
It comprises a case 1, a charcoal 2 and a mineral powder 3 sealed inside the case 1.

The case 1 is formed by integrally fixing a case body 1a having a storage portion therein and a lid 1b. In addition,
The shape of the case 1 is fired into an arbitrary shape such as a cylindrical container, a rectangular container, a spherical container, or the like, depending on the application, in addition to a flat container.

In this case, the size of the case 1 is not particularly limited, but it is made of an alumina-based ceramic having a porosity of 30%, and has an outer diameter of 50 mm and a height of 20 mm.
It was baked into a flat container of mm.

In the case 1, powder 20 of charcoal 2 is placed.
g and 20 g of the mineral powder 3 (mixing ratio: 60% of calcium, 10% of magnesium, 30% of calcium).

When the rice was put on rice in a rice cooker and cooked using the above-mentioned water quality improving device, the gloss of the cooked rice increased and the taste was improved as compared with the case where the water quality improving device was not used. Improved.

By the way, the above embodiment has been described with respect to a case where the water quality improving device according to the present invention is used in a rice cooker. Water quality can be improved.

[0016]

According to the present invention, since charcoal and mineral powders are sealed in a ceramic case, it is easy to handle and has a good appearance, and the synergy between the ceramics and the internal inclusion makes it possible to simplify the quality of tap water. It can be cooked and delicious rice can be cooked when used during cooking.

Further, since the structure is simple, excellent effects such as mass production at low cost can be obtained.
