Description

Technical Field

[0001] The present invention relates to a water server capable of adding minerals to tap water, well water, etc. and supplying it as delicious drinking water.

Background Art

[0002] Generally, a water server uses commercially available mineral water filled in a bottle of about 5 to 10 liters, and this bottle is set on the upper part of the server body for drinking use. In such a structure, when the bottle becomes empty, it is necessary to lift the heavy bottle filled with mineral water and set it on the server body, which not only imposes severe labor but also has a problem of requiring a large space for storing the inventory of the bottles. There is also a problem that the purchase cost of mineral water soars.

[0003] Therefore, in Patent Document 1, which is a prior application by the present applicant, a water server is disclosed in which a tank having a two-stage structure of an upper tank and a lower tank is provided on the upper part of the server body, and a ceramic filter made of ceramic containing activated carbon is provided on the upper tank side.

[0004] In this water server, tap water is poured into the tank, mixed with a mineral aggregation liquid, and purified by a ceramic filter containing activated carbon, thereby making it possible to obtain delicious drinking water. As a result, it is possible to eliminate the need for a heavy and bulky bottle filled with mineral water, and since tap water is used, it can be made inexpensive.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, the water dispenser described in Patent Document 1 has a two-tiered tank structure consisting of an upper tank and a lower tank, with a ceramic filter made of ceramic containing activated carbon installed on the upper tank side. However, there was a problem in that it could not adequately purify the water.

[0007] This invention was made in consideration of these problems, and aims to provide a water dispenser that mineralizes tap water and other water to make it drinkable, and that can efficiently obtain a sufficient water purification effect. [Means for solving the problem]

[0008] The present invention relates to a water server comprising a server body equipped with a water dispensing nozzle and a tank provided at the top of the server body for supplying water to the water dispensing nozzle, wherein the tank is formed by an upper tank and a lower tank, a ceramic filter containing ceramic is provided on the upper tank side, and a cartridge filter containing activated carbon is provided on the lower tank side, the upper tank is filled with mixed water obtained by mixing water with a mineral condensate containing mineral ions extracted from mineral ore, and the mixed water filled in the upper tank is continuously filtered by the ceramic filter and the cartridge filter.

[0009] Another feature of the water server of the present invention is a water server comprising a server body equipped with a water dispensing nozzle and a tank provided at the top of the server body for supplying water to the water dispensing nozzle, wherein the tank is formed by an upper tank and a lower tank, a first filter is provided on the upper tank side, and a second filter having a different function from the first filter is provided on the lower tank side, the upper tank is filled with mixed water obtained by mixing a mineral condensate containing mineral ions extracted from mineral ore with water, and the mixed water filled in the upper tank is continuously filtered by the first filter and the second filter. [Effects of the Invention]

[0010] According to the present invention, water can be mineralized simply by mixing a mineral coagulation solution with water.

[0011] Furthermore, according to the present invention, by providing a ceramic filter containing ceramics on the upper tank side of a two-stage tank consisting of an upper tank and a lower tank, and a cartridge filter containing activated carbon on the lower tank side of the two-stage tank, a sufficient water purification effect can be efficiently obtained. [Brief explanation of the drawing]

[Figure 4] Figure 1 is a side view of the ceramic filter 15 shown in Figure 1. [Figure 5] Figure 1 is a partial explanatory diagram of the assembly process of the water server 1 shown in Figure 1, where (a) is a side view of the state with the drip tray 5 installed on the server body 2, (b) is a side view of the state with the float 7 attached to the bottom of the water purifier 3b, (c) is a side view of the state with the cartridge filter 11 attached to the cartridge stand 13, and (d) is a side view of the state with the ceramic filter 15 attached to the filtration container 3a. [Modes for carrying out the invention]

[0013] Figure 1 shows an overall view of the water dispenser 1 according to one embodiment of the present invention. Furthermore, this water dispenser 1 is equipped with a pitcher 4a and a mineral condensate container 4b, which will be described later.

[0014] As shown in Figure 1, the water server 1 supplies drinking water to the user and is composed of a server body 2 and a tank 3. The tank 3 consists of an upper tank 3a which is a filtration container and a lower tank 3b which is a water purifier. The server body 2 has a recessed window section 2a in the middle of its height, and water nozzles 6 and 7 are provided inside this window section 2a. Nozzle 6 is for dispensing cold water, and nozzle 7 is for dispensing hot water. The server body 2 contains an internal chilled water tank for storing water in a cooled state and an internal hot water tank for storing water in a heated state (neither of which are shown in the illustration). Nozzle 6 is connected to the internal chilled water tank, and nozzle 7 is connected to the internal hot water tank. The internal chilled water tank and the internal hot water tank are connected via piping (not shown) so that water is supplied from tank 3 at the top of the server body 2.

[0015] The tank 3 supplies the mineralized water to the server main body 2 and is placed on the upper part of the server main body 2. The tank 3 has a two-stage structure consisting of an upper tank 3a made of a filtration container and a lower tank 3b made of a water conditioner.

[0016] Next, the structure of the tank 3 will be described. FIG. 2 is an exploded perspective view showing the components related to the upper tank 3 of the water server 1. As shown in FIG. 2, a plastic tray 5 installed on the server main body 2 is provided on the server main body 2, and the water conditioner (lower tank) 3b is installed on this tray 5. That is, the water conditioner 3b is installed on the server main body 2 via the tray 5. Note that the tray 5 is made of a white plastic container. Here, as shown in FIGS. 1 and 5(a), in the state where the water conditioner 3b is installed on the server main body 2 via the tray 5, a small gap 8 is provided between the tray 5 and the server main body 2. This gap 8 facilitates the removal of dust and the like. As shown in FIG. 2, a float 7 is attached to the bottom of the water conditioner 3b, and in the state where the water conditioner 3b is installed on the server main body 2, the float 7 is positioned below the water conditioner 3b. Note that the water conditioner 3b is made of a transparent polygonal plastic container and is adapted to pass ultraviolet rays.

[0017] As shown in FIG. 2, a lid 9 of the water conditioner 3b is provided on the water conditioner 3b, and a cartridge base 13 for attaching a cartridge filter 11 containing activated carbon is installed on the lid 9 of the water conditioner 3b. Note that the lid 9 and the cartridge base 13 are made of white plastic. When the cartridge base 13 with the cartridge filter 11 attached is installed on the lid 9 of the water conditioner 3b, the cartridge filter 11 is positioned above the water conditioner 3b. Regarding the method of attaching the cartridge filter 11 to the cartridge base 13, it will be described in detail in the method of assembling the water server 1, which will be described later. Next, a filtration container (upper tank) 3a to which the ceramic filter 15 is attached is installed on the lid 9 of the water conditioner 3b. When installed on the lid 9 of the water conditioner 3b with the ceramic filter 15 attached to the filtration container 3a, the ceramic filter 15 is positioned at the lower part of the filtration container 3a. Regarding the method of attaching the ceramic filter 15 to the filtration container 3a, it will also be described in detail in the method of assembling the water server 1, which will be described later. A lid 17 is placed on the filtration container 3a, thereby preventing dust in the air from falling into the filtration container 3a. The lid 17 is also made of white plastic.

[0018] Next, the configuration of the cartridge filter 11 will be described in detail. FIG. 3 is a detailed configuration diagram of the cartridge filter 11, (a) is a side view of the cartridge filter 11, (b) is a top view of the cartridge filter 11, and (c) is a side view showing a modified example of the cartridge filter 11. Here, as shown in FIG. 3(a), the cartridge filter 11 has a vertically long rectangular shape when viewed from the side, and a male screw portion 11a that engages with a female screw portion 13a (see FIG. 2) provided inside the cartridge base 13 is provided at its upper part. The cartridge filter 11 mainly has a filter made of activated carbon and mainly has a function of removing impurities.

[0019] In this embodiment, as shown in FIG. 3(b), it has a four-layer structure of an activated carbon layer 11b, a zeolite layer 11c, a ceramic ball layer 11d, and an Ag ion layer 11e in order from the outer peripheral side. However, the order of the four layers 11b to 11e may be any order other than the order shown in FIG. 3(b).

[0020] As shown in Figure 3(b), an opening 11f is provided inside the four layers 11b to 11e, which make up the four-layer structure. When the ceramic filter 15, which will be described later, is installed during assembly, the lower part 15b (described later) of the water droplet is inserted into the opening 11f. As a result, the water from the lower part 15b of the water droplet of the ceramic filter 15 (water filtered by the ceramic filter 15) flows into the opening 11f of the cartridge filter 11 and is continuously filtered by passing through the four layers 11b to 11e of the cartridge filter 11. In this way, the water is continuously filtered by the ceramic filter 15 and the cartridge filter 11, which have different functions, thus providing higher quality filtered water.

[0021] Furthermore, the outer periphery 11g of the cartridge filter 11 is made of a transparent plastic container that allows ultraviolet light to pass through. As a result, the activated carbon layer 11b is directly exposed to ultraviolet light through the transparent polygonal plastic container of the water purifier 3b and the transparent plastic container of the outer circumference 11g of the cartridge filter 11, so that the activated carbon is always revived to a fresh state. Therefore, it is possible to prevent odors such as moldy smells from developing in the activated carbon. In the above embodiment, four layers 11b to 11e were formed sequentially from the outer periphery, but the invention is not limited to this configuration. As shown in Figure 3(c), four layers 11b to 11e may also be formed sequentially from top to bottom in the vertical direction. Furthermore, in the above embodiment, the cartridge filter 11 was formed from four layers 11b to 11e, including an activated carbon layer 11b, but it may also consist of only an activated carbon layer.

[0022] A key feature of this invention is the provision of a cartridge filter 11, which consists of a separate activated carbon layer from the ceramic filter 15, on the lower tank 3b side. Furthermore, the activated carbon layer 11b of this cartridge filter 11 is directly exposed to ultraviolet light through the transparent polygonal plastic container of the water purifier 3b and the transparent plastic container of the outer circumference 11g of the cartridge filter 11, so the activated carbon is constantly revived to a fresh state, eliminating the need for replacement and allowing for semi-permanent use.

[0023] Next, we will explain the configuration of the ceramic filter 15 in detail. As shown in Figure 2, a passage 3a1 consisting of small circular holes leading to the water purifier (lower tank) 3b is opened at the bottom of the filtration container (upper tank) 3a, and a ceramic filter 15 containing ceramic is attached to this passage 3a1, which will be explained in detail later. As shown in Figure 4, the ceramic filter 15 is formed into a dome shape with a thickness of 0.5 to 2 cm, preferably about 1 cm, by firing ceramic powder. A protruding water droplet lower part 15b is formed on its bottom surface 15a for discharging filtered water, and it mainly has a sterilization function. A female threaded portion is provided on the water droplet lower part 15b of the ceramic filter 15. By attaching the lower part 15b of the ceramic filter 15 to the connecting passage 3a1, the water in the filtration container 3a is filtered by the ceramic filter 15 and then falls by its own weight from the connecting passage 3a1 to the opening 11f of the cartridge filter 11 in the lower tank 12.

[0024] In this case, the ceramic filter 15 is fired to a particle size of 0.1 to 1.0 μm, preferably about 0.5 μm. This particle size allows for filtering, for example, 1 liter of water in about 40 to 60 minutes. The particle size and filtration capacity of the ceramic filter 15 can be changed as appropriate. Through filtration by the ceramic filter 15, the aggregates in the filtration container 3a are filtered out, and the clean water falls into the water purifier 3b. As mentioned above, the water is continuously filtered by the ceramic filter 15 and the cartridge filter 11, which have different functions, making it possible to obtain higher quality filtered water.

[0025] Next, the assembly method of water dispenser 1 will be explained with reference to Figures 2 and 5(a) to (d). First, before assembling water server 1, fill the included pitcher 4a with water, then place the cartridge filter 11 and ceramic filter 15 into the water in that order to remove air from the cartridge filter 11 and ceramic filter 15.

[0026] Subsequently, as shown in Figures 2 and 5(a), a plastic tray 5 is placed on the server body 2. Here, a circular hole 2a is provided on the top surface of the server body 2, and a hole 5a is formed in the tray 5 to match the circular hole 2a. Then, as shown in Figure 5(b), the float 7 is attached to the bottom of the water purifier (lower tank) 3b. Specifically, as shown in Figure 2, the nut 7b attached to the protrusion 7a on the upper surface of the float 7 is removed, the protrusion 7a on the upper surface of the float 7 is inserted into the small hole 3b1 provided in the bottom of the water purifier 3b, and the nut 7b is screwed onto the protrusion 7a to attach it. The water purifier 3b with the float 7 attached is placed on the tray 5 on the server body 2. At this time, the float 7 is inserted into the circular hole 2a provided on the top surface of the server body 2 (see Figure 2). Then, the lid 9 is attached to the water purifier 3b. The lid 9 has a hole 9a formed in it.

[0027] Next, as shown in Figure 5(c), the cartridge filter 11 is attached to the cartridge base 13. Specifically, as shown in Figure 2, the upper part of the cartridge filter 11 is attached to the lower surface of the cartridge base 13, which is installed on top of the lid 9. Here, a hole 13a is formed in the cartridge base 13, and a female threaded portion is provided inside the hole 13a, which engages with a male threaded portion 11a (see Figure 3(a)) provided on the upper part of the cartridge filter 11. The upper part of the cartridge filter 11 is attached to the lower surface of the cartridge base 13 by engaging the female threaded portion of the hole 13a of the cartridge base 13 with the male threaded portion 11a on the upper part of the cartridge filter 11.

[0028] The cartridge stand 13, on which the cartridge filter 11 is attached, is placed on top of the lid 9 of the water purifier 3b. Here, the cartridge stand 13 is designed to fit together with the lid 9 of the water purifier 3b. With the cartridge filter 11 attached to the cartridge base 13 and placed on top of the lid 9 of the water purifier 3b, the lower part of the cartridge filter 11 passes through the hole 9a in the lid 9 and enters the water purifier 3b, so that the cartridge filter 11 is located in the upper part of the water purifier 3b. As mentioned above, the outer periphery 11g of the cartridge filter 11 is made of a transparent plastic container that allows ultraviolet light to pass through. Therefore, the activated carbon is directly exposed to ultraviolet light through the transparent polygonal plastic container of the water purifier 3b and the transparent plastic container of the outer periphery 11g of the cartridge filter 11, and the activated carbon is constantly revived to a fresh state. As a result, odors such as moldy smells in the activated carbon can be prevented.

[0029] Next, as shown in Figure 5(d), the ceramic filter 15 is attached to the filtration container (upper tank) 3a, and the filtration container 3a with the ceramic filter 15 fixed to it is placed on the cartridge stand 13 on top of the water purifier 3b. Specifically, as shown in Figure 2, a packing 15c is attached to the lower part 15b of the ceramic filter 15, and the lower part 15b of the ceramic filter 15 with the packing 15c attached is inserted into the communication passage 3a1 of the filtration container 3a. With the lower part 15b of the ceramic filter 15 with the packing 15c attached inserted into the communication passage 3a1 of the filtration container 3a, a nut 15d is attached to the female threaded part of the lower part 15b and tightened. In other words, the lower surface of the ceramic filter 15 is fixed to the filtration container 3a via the packing 15c.

[0030] As mentioned above, the water from the lower part 15b of the water droplet of the ceramic filter 15 (water filtered by the ceramic filter 15) flows into the opening 11f of the cartridge filter 11 (see Figure 3(b)) and is continuously filtered by the cartridge filter 11. Specifically, a ceramic filter 15 is provided on the filtration container (upper tank) 3a side of the connecting passage 3a1 between the filtration container (upper tank) 3a and the water purifier (lower tank) 3b, and a cartridge filter 11 is provided on the water purifier (lower tank) 3b side of the connecting passage 3a1. Therefore, the water in the filtration container (upper tank) 3a is continuously filtered by both the ceramic filter 15 and the cartridge filter 11. In this way, the water is continuously filtered by the ceramic filter 15 and the cartridge filter 11, which have different functions, making it possible to obtain higher quality filtered water. Finally, place the lid 17 on top of the filter container 3a to complete the assembly.

[0031] Next, we will explain how to use the water dispenser 1 mentioned above. As mentioned above, in the preliminary stage of assembling the water server 1, the cartridge filter 11 and ceramic filter 15 are placed in the water in the included pitcher 4a, and air is removed from the cartridge filter 11 and ceramic filter 15.

[0032] Once the assembly of the water server 1 described above is complete, first, pour the mineral coagulation liquid (Pure Drop) from the mineral coagulation liquid container 4b into the included pitcher 4a, then add water (tap water, well water, etc.) and stir to make mineral water. Here, approximately 1 ml (1 dropper) of mineral condensate is used to create 5 liters of mineral water. Then, the mineral water produced is poured into the filtration container (upper tank) 3a. When this mineral coagulation solution is mixed with water and the resulting mixture is filled into the filtration container 3a, the mineral ions contained in the mineral coagulation solution disperse in the water within the filtration container 3a, binding to water molecules or coordinating around water molecules to mineralize the water. Here, the mineral coagulant is an aqueous coagulant obtained by acid-treating mineral ore, mainly composed of mica, with edible acid to extract mineral ions. In other words, it is a liquid containing mineral ions extracted from mineral ore, and the mineral ore mainly used is mica. Mica is a silicate mineral containing minerals such as alkali metals, alkaline earth metals, iron, and aluminum, and one or more types such as biotite, muscovite, phlogopite, and thiamite can be selected and used. Mica is preferably used in powder form for the extraction of mineral ions, but it may also be used in crystalline form.

[0033] Mineral ions are extracted from mica by acid treatment of mica in powder or crystalline form. Acid treatment is performed by dissolving mica in an edible acid such as acetic acid or citric acid. After dissolution, the solution is concentrated to obtain a liquid mineral coagulant. This mineral coagulant contains the minerals present in mica in high concentrations in ionic form. Table 1 shows the analysis results of the mineral coagulant.

[0034] As shown in the table, the mineral coagulation solution contains not only major minerals essential for the human body such as sodium, phosphorus, and iron, but also trace minerals such as fluorine and silicon. The mineral coagulation solution acts to mineralize water, and for mineralization, it is preferable that it contains at least Ca ions, K ions, Fe ions, Zn ions, Na ions, Cu ions, Mn ions, Cr ions, Al ions, Ni ions, Si ions, P ions, Ti ions, F ions, and Co ions. In other words, the mineral coagulation solution contains at least Ca ions, K ions, Fe ions, Zn ions, Na ions, Cu ions, Mn ions, Cr ions, Al ions, Ni ions, Si ions, P ions, Ti ions, F ions, and Co ions.

[0035] [Table 1]

[0036] Mineral coagulation solution is added in small amounts to water such as tap water or well water. This process mineralizes water. For example, in the case of the mineral coagulation solution with the components listed in Table 1, adding 1 cc to 3-5 liters of tap water can mineralize it.

[0037] In water mixed with mineral condensate, mineral ions in the mineral condensate mineralize the water by binding to water molecules or coordinating around them, surrounding the water molecules. Furthermore, the binding of mineral ions to water molecules or their coordination prevents the growth of bacteria and the oxidation of the water. Furthermore, the bonding and coordination of mineral ions impart flavor and smoothness to the water. In addition, the bonding and coordination of mineral ions deodorize and decolorize the water. These actions of mineral ions mineralize the water in a short time, approximately 5 to 30 minutes. Moreover, mineral ions coagulate and precipitate organic matter in tap water.

[0038] When mineral water is poured into the filtration container (upper tank) 3a, it is filtered and purified by the ceramic filter 15 and cartridge filter 11 as it moves from the filtration container (upper tank) 3a to the water purifier (lower tank) 3b. Here, the organic matter that has aggregated and precipitated as described above is also filtered out and removed by the ceramic filter 15. In other words, water from the lower part 15b of the ceramic filter 15 (water filtered by the ceramic filter 15) flows into the opening 11f of the cartridge filter 11, is continuously filtered by the cartridge filter 11, and is filled into the water purifier (lower tank) 3b, as well as into the internal cold water tank and the internal hot water tank. Here, harmful substances such as chlorine, odors, trihalomethanes, and lead are adsorbed and removed mainly by activated carbon in the cartridge filter 11. As a result, tap water becomes delicious water that can be dispensed from the nozzle of the server unit. The ceramic filter 15 primarily serves a sterilization function, while the cartridge filter 11 primarily serves to remove impurities.

[0039] In this way, the water is continuously filtered by the ceramic filter 15 and the cartridge filter 11, which have different functions, making it possible to obtain higher quality filtered water. Then, by plugging the power cord, which is located on the back of the water server 1 (not shown in the diagram), into an outlet and turning on the power, the purified water in the internal cold water tank is cooled and the purified water in the internal hot water tank is heated. Therefore, operating nozzle 6 will dispense cold water, and operating nozzle 7 will dispense hot water.

[0040] As described above, according to the water server 1 of the embodiment of the present invention, in the filtration container (upper tank) 3a, mineral ions contained in the mineral coagulation liquid disperse in the water in the filtration container 3a, mineralizing the water. This imparts flavor to the water, making it smoother, and the mineral ions prevent oxidation, suppress bacterial growth, and further coagulate organic matter in the water, thereby suppressing water corrosion. Furthermore, a ceramic filter 15 made of fired ceramic powder is installed on the filtration container (upper tank) 3a side, and a cartridge filter 11 mainly made of activated carbon is installed on the water purifier (lower tank) 3b side, so that water is purified continuously from the ceramic filter 15 to the cartridge filter 11, thereby enabling efficient and sufficient water purification. Here, the ceramic filter 15 primarily has a sterilization function, and the cartridge filter 11 primarily has a function of removing impurities. Therefore, since the water is continuously filtered by the ceramic filter 15 and the cartridge filter 11, which have different functions, it becomes possible to obtain higher quality filtered water.

[0041] Furthermore, since the water purifier 3b consists of a transparent polygonal plastic container, and the outer periphery 11g of the cartridge filter 11 also consists of a transparent plastic container, both of which allow ultraviolet light to pass through, the activated carbon is directly exposed to ultraviolet light through the transparent polygonal plastic container of the water purifier 3b and the transparent plastic container of the outer periphery 11g of the cartridge filter 11, so that the activated carbon is constantly revived to a fresh state. As a result, it becomes possible to prevent odors such as moldy smells from developing in the activated carbon. Furthermore, this cartridge filter 11 allows the activated carbon to be directly exposed to ultraviolet light through the transparent polygonal plastic container of the water purifier 3b and the transparent plastic container of the cartridge filter 11, so that the activated carbon is constantly revived to a fresh state. As a result, there is no need to replace the cartridge filter 11, and it can be used semi-permanently. Furthermore, when the water purifier 3b is installed on the server body 2 via the drip tray 5, a small gap 8 is provided between the drip tray 5 and the server body 2. This gap 8 makes it easy to remove dust and other debris.

[0042] Therefore, according to the present invention, since water can be mineralized simply by mixing the mineral coagulation liquid with water, there is no need to wait a long time for minerals to dissolve into the water as with conventional cartridges or water purification tanks, and delicious water can be produced in a short time, making it convenient to use. Furthermore, by using two filters with different functions—a ceramic filter made from fired ceramic powder and a cartridge filter mainly composed of activated carbon—water purification is performed continuously, allowing for efficient and sufficient water purification. Furthermore, because the activated carbon in the cartridge filter is directly exposed to ultraviolet light, the activated carbon is constantly revitalized, eliminating the need to replace the cartridge filter and allowing for semi-permanent use. This makes it easy to mineralize water and can be easily handled in ordinary households. [Explanation of Symbols]
