The granulated body with a reduced internal gravity due to the voids inside, easily swings due to the water flow in the storage container, and the surface of the granular body has multiple irregularities made of powder particles For this reason, the effect of the rocking and the unevenness increases the contact efficiency with water, and the dissolution efficiency of the inorganic compound in water can be further increased.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a structural diagram of a melting apparatus according to the first embodiment of the present invention.

  In FIG. 1, an inorganic compound 11 is soluble in water and has a surface provided with a plurality of irregularities, which is accommodated in an inorganic compound storage container 12. By the irregularities provided on the surface, the inorganic compound 11 The specific surface area of the inorganic compound with respect to the water flow flowing in the storage container 12 can be increased.

  As a specific means for obtaining the inorganic compound 11 having a plurality of irregularities on the surface, it is placed in a ball mill together with an inorganic compound having no irregularities on the surface and particles having a hardness higher than that of the inorganic compound and different specific gravity. Then, the inorganic compound which provided the unevenness | corrugation can be obtained by disperse | distributing in a solvent insoluble with respect to an inorganic compound, and carrying out specific gravity separation of an inorganic compound and particle | grains.

  In addition, an inorganic compound having an uneven fracture surface can be obtained by pulverizing an inorganic compound having no irregularities on the surface by applying a physical impact. The specific examples are merely examples, and are not limited as means for obtaining an inorganic compound having irregularities.

  When the inorganic compound 11 having a plurality of irregularities on the surface is filled in a multilayer shape, a porous space is formed in the inorganic compound storage container 12. The filtering means 13 has a plurality of small holes and is stored in the filtering means storage container 14. The inorganic compound storage container 12 and the filtration means storage container 14 are sequentially communicated by a water circuit 15, and the dissolution apparatus 16 is configured so that the inorganic compound storage container 12 is on the upstream side of the filtration means storage container 14.

  In addition, in the inorganic compound storage container 12, not only the inorganic compound 11 having irregularities on the surface but also powder particles of the inorganic compound 11 may be mixed.

About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while contacting the inorganic compound 11 having a plurality of irregularities on the surface filled in the inorganic compound storage container 12. Since water has viscosity, a velocity boundary layer is generated from the surface of the inorganic compound 11 to the region near the surface when passing through the porous space. FIG. 3 is a diagram showing the state of the velocity boundary layer. The flow velocity of the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the central portion of the porous space has a large distribution. Since the inorganic compound 11 is soluble in water, 11 surface molecules near the surface of the inorganic compound 11 are dissolved in water near the surface, and the dissolution concentration of water increases. Since the water near the surface has a low flow rate, the dissolved concentration has a high value.

  On the other hand, the dissolved concentration of water flowing in the center of the porous space having a high flow rate is low. At this time, if there is a difference in the concentration of the inorganic compound dissolved in water, the lower substance moves from the higher one according to the concentration difference (Fick's law), so the inorganic compound dissolved in the water near the surface Move to low center water. By utilizing this principle of substance diffusion, the inorganic compound 11 can be dissolved in water in the porous space.

  Furthermore, due to the plurality of irregularities formed on the surface of the inorganic compound, the contact surface area of the inorganic compound 11 with respect to water is several times or more than that without the irregularities, the dissolution concentration near the surface of the inorganic compound 11 is further increased, and the porous space The concentration difference from the central part of the water increases, and the amount of the inorganic compound 11 dissolved in water can be increased.

The action of increasing the dissolution efficiency of the inorganic compound 11 in water makes it possible not only to use the inorganic compound 11 having a low solubility in water, but also to reduce the filling amount of the inorganic compound 11 into the dissolution apparatus 16. The cost reduction by this can also be measured.
The filtering means 13 prevents the granules of the inorganic compound 11 from flowing out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12.

  As described above, in the present embodiment, the water circuit, the storage means for storing the inorganic compound having a plurality of projections and depressions on the surface, and the filtering means, the water flowing through the water circuit is stored in the storage means. The stored inorganic compound was dissolved, and a hot water supply apparatus provided with a dissolving device configured such that the dissolved inorganic compound passed through the filtering means was obtained.

  This makes it possible to increase the dissolution efficiency of the inorganic compound in water using the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in the dissolved concentration between water and the inorganic compound. Therefore, it is possible to provide a hot water supply apparatus that improves the melting characteristics of inorganic compounds, is compact, lowers cost, and further reduces power consumption while reducing power supply circuits and insulation circuits that have been required.

  In the present embodiment, the direction of the water flow with respect to the inorganic compound storage container 12 in the figure is an upward flow, but the flow direction is not limited, and the downward direction (FIG. 2) and the lateral direction are not limited. It is also possible to arrange. For example, when the flow direction is set to the upward direction, the particles of the inorganic compound 11 clogged in the filtering means 13 after the water flow is stopped are easily separated from the filtering means 13 by gravity drop, and the aging of the filtering means 13 is improved. It becomes possible to suppress clogging.

  In addition, when the inorganic compound is a zinc compound containing zinc (such as zinc oxide or zinc carbonate), the following effects can be obtained. Zinc is one of the essential elements of humans with relatively large demands, and is easily deficient when supplied from a normal diet. It is an element added to foods for the purpose of enhancing nutrition. On the other hand, the nutrition enhancement by percutaneous absorption can be performed during bathing by supplying water in which zinc is dissolved in the bathtub.

  In addition, zinc oxide, a zinc compound, is a material that has been approved under the pharmacopoeia and cosmetic raw material standards. It mainly has effects on the stratum corneum of human skin, such as astringent action and anti-inflammatory action, and the skin corners. Layer improvements can also be made.

  FIG. 4 is an example showing the relationship between the dimensions of the inorganic compound 11 and the filtering means 13 of the dissolving apparatus. In FIG. 4, the filtering means 13 is composed of a plurality of small holes 13a, 13b, 13c having different diameters.

  FIG. 5 is a configuration example of the filtering means 13. (A) forms a square-shaped small hole with a linear fiber. (B) is a plate having a predetermined thickness and small holes having a plurality of types of diameters. (C) forms a porous space by using a granular non-dissolving material as a multilayer. In any case, when the granules of the inorganic compound 11 are about to flow out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12, this is prevented, but the configuration and shape are not limited thereto.

  The dissolution concentration flowing out of the dissolution apparatus 16 is determined by the flow rate of water passing through the inorganic compound storage container 12, the surface area of the inorganic compound 11 in contact with water, and the like. When the dissolution concentration of the dissolution apparatus 16 is set to a predetermined value, the total surface area of the inorganic compound 11 needs to be within a certain range, so the particle size of the inorganic compound 11 stored in the inorganic compound storage container 12 of FIG. It is necessary to use the one selected for the size within the range.

  Since the selection causes a cost increase, among the inorganic compounds 11 having a plurality of diameters, the diameter D2 of the small hole 13a of the filtering means 13 is D2 <with respect to the maximum particle diameter D1 of the inorganic compound 11. In the case of D1, the following effects can be obtained. The inorganic compound 11 having a particle size less than D2 flows out from the small holes 13a, 13b, and 13c. In the initial stage of use, those having a small particle size flow out of the melting device 16, but after a predetermined time has passed, the inorganic compound 11 having a particle size of D2 or more continues to be stored in the inorganic compound storage container 12. When this state is formed, it is equivalent to selecting the particle size of the inorganic compound 11 to a size within a certain range. Therefore, even if the inorganic compound 11 in which the sizes are mixed is used, the target concentration is dissolved in water.

FIG. 6 shows a structural diagram of a melting apparatus according to the second embodiment of the present invention. In addition, about the same structure as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In FIG. 6, the inorganic compound 11 is a granular body 11 a obtained by combining a plurality of powder particles, or a mixture of the powder particles 11 b and the granular body 11 a, and is stored in the inorganic compound storage container 12.

  FIG. 7 shows an enlarged view of the granular inorganic compound. The granular material 11a of the inorganic compound 11 is formed by adhering the powder particles 11b of the inorganic compound through bonding means such as a binder to form a bonded body having a predetermined size and shape.

  As specific manufacturing means of the granular body 11a, a general-purpose manufacturing means such as a granulator is used to form the granular body 11a having a desired size and shape, and then heat treatment such as baking is performed in a subsequent process. Thus, the binding force of the binder between the granular bodies 11a can be increased, and the granular body 11a having a certain strength or more can be obtained.

  The shape of the granular body 11a is not particularly limited to a shape such as a substantially spherical shape, a substantially cubic shape, or a substantially rectangular parallelepiped shape. For example, in the case of a substantially spherical shape, the substantially spherical granular shape is placed in the inorganic compound storage container 12. By filling in multiple layers, the granular body 11a is placed in point contact with the adjacent granular body 11a, forming a gap that becomes a water passage between the granular bodies 11a, and inorganic. The pressure loss of the water flow in the compound storage container 12 can be reduced.

Further, as described above, since the granular body 11a is a product in which a plurality of powder particles 11b of the inorganic compound 11 are combined in a substantially spherical shape, the surface of the granular body 11a is shown in FIG. As described above, at least an uneven portion 11c having an opening diameter equivalent to the diameter of the powder particle 11b and a depth equivalent to the same radius is formed, and the specific surface area with respect to water contacting the granular body 11a has no uneven portion. It will increase compared to the state of.

  Moreover, since the granular body 11a forms several space | gap inside the granular body 11a when couple | bonding the powder grain 11b, compared with the non-granular body of the same volume, specific gravity becomes small. For this reason, as shown in FIG. 5, when water flows into the inorganic compound storage container 12, the granular body 11 a has a small specific gravity, so that it swings randomly in the inorganic compound storage container 12 and is adjacent. The distance between the granular bodies 11a is larger than when the water flow is stopped.

  The granular body 11a of the inorganic compound 11 filled in the inorganic compound storage container 12 may be filled with the same diameter or a mixture of a plurality of spherical diameters. This eliminates the need for sieving the granule diameter, so that the cost can be kept low. Moreover, the uneven | corrugated size formed in the surface of the granular body 11a can also be adjusted arbitrarily by increasing / decreasing the particle diameter of the powder grain 11b of the inorganic compound 11. FIG.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while being in contact with the granular material 11a and the powder particles 11b of the inorganic compound 11 filled in the inorganic compound storage container 12.

The granular body 11a of the inorganic compound 11 in the inorganic compound storage container 12 receives the kinetic energy of the water flow, swings in the container, and maintains a state where the distance between the adjacent granular bodies 11a is expanded. Water flows between the granular bodies 11a. As described in the first embodiment, the inorganic compound 11 dissolves the inorganic compound 11 in water in which the lower substance moves from the higher one according to the concentration difference between the compound surface and flowing water (Fick's law). Can be
In the present embodiment, the granular body 11a swings to increase the distance from the center of the water, and the concentration difference between the inorganic compound surface and water becomes larger. The amount dissolved in water can be increased.

  As described above, in the present embodiment, the granular material 11a in which the plurality of powder particles 11b of the inorganic compound 11 are combined, or the mixture of the powder particles 11b and the granular material 11a is used as an inorganic compound storage container. 12, the inorganic compound 11 of the granular body 11a is a dissolving device provided with a plurality of irregularities 11c on the surface of the granules.

  As a result, the inorganic compound can be dissolved in water based on the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in dissolution concentration between water and the inorganic compound. The granular body 11a to which the particles 11b are bonded has a void in the interior, so that the specific gravity is lightened, easily swings due to the water flow in the inorganic compound storage container 12, and the surface of the granular body 11a is a powder. Since there are a plurality of irregularities 11c composed of the grains 11b, the effect of the rocking and irregularities increases the contact efficiency with water, and the dissolution efficiency of the inorganic compound in water can be further increased.

(Embodiment 3)
FIG. 8 shows a structural diagram of a melting apparatus according to the third embodiment of the present invention. FIG. 9 shows a plurality of shape examples of the inorganic compound molded body. In addition, about the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Reference numeral 17 denotes an inorganic compound molded body obtained by molding and solidifying the powder particles 11b of the inorganic compound 11 into a predetermined shape.

  As a specific manufacturing method of the inorganic compound molded body 17, powder particles 11 b of the inorganic compound 11, a binder component, and a solvent such as pure water are kneaded and formed into a predetermined shape using a mold, and then fired, etc. By performing the heat treatment in a subsequent process, the binding strength of the binder is increased and the strength as a molded body is ensured.

  In addition, the external dimension of the inorganic compound molded body 17 of this Embodiment is formed larger than the projection diameter with respect to the inorganic compound molded body 17 of the water circuit 15 connected to the inorganic compound storage container 12, and the inorganic compound storage container 12 is formed. When the water flows, the inorganic compound molded body 17 can prevent the downstream water circuit 15 from flowing out, so that it is not necessary to mount the filtering means 13 and the filtering means storage container 14 in the dissolving device 16. Not only can the construction cost of the melting device 16 be further reduced, but it is also possible to drastically remove the risk of quality degradation such as a reduction in the flow rate of the water circuit due to clogging of the filtering means 13.

  In addition, since the inorganic compound molded body 17 is a product obtained by molding the powder particles 11b, the surface of the granular body 11a has at least the diameter of the powder particles 11b as in the granular body 11a of the first embodiment. The uneven part 11c having the same opening diameter and the same depth as the radius is formed, and the specific surface area with respect to the water contacting the granular body 11a is increased as compared with the state without the uneven part.

  In addition, the inorganic compound molded body 17 can be formed in an arbitrary shape by using a molding die, and as shown in FIG. The contact area is increased to increase the dissolution efficiency of the inorganic compound 11 in water, and as shown in FIG. 7 (b), not only the contact area against water is increased, but also water is formed. Since resistance to the flow can be lowered, as shown in FIG. 8B, a plurality of honeycomb-shaped inorganic compound molded bodies 17 can be stacked and mounted on the inorganic compound storage container 12.

  As described above, in the present embodiment, since the outer dimension of the inorganic compound molded body 17 is larger than the inner diameter of the pipe of the water circuit 15 connected to the inorganic compound storage container 12, the water flow in the water circuit 15 Since the entire inorganic compound molded body 17 cannot flow out to the water circuit 15 by riding, it is not necessary to install a holding means such as a filtering means for holding the inorganic compound molded body 17 in the inorganic compound storage container 12, and the inorganic compound stored The construction cost of the container 12 can be reduced, and the surface of the inorganic compound molded body 17 is provided with a plurality of irregularities 11c. Therefore, the relative contact surface area of the inorganic compound molded body 17 with respect to water increases, and the water The cost can be further reduced while stabilizing the amount of the inorganic compound dissolved at a high level.

FIG. 10 shows a configuration diagram of a hot water supply apparatus according to the fourth embodiment of the present invention.

  In FIG. 10, a compressor 22, a hot water supply heat exchanger 23, a decompression unit 24, and an evaporator 25 are annularly connected in order by a refrigerant circuit 26 to constitute a heat pump unit 21. Water is stored in a hot water storage tank 28 of the hot water storage unit 27, and a hot water discharge circuit 30 is a circuit that connects the hot water storage tank 28, a hot water supply pump 29, a hot water supply heat exchanger 23, and a hot water storage tank 28 in this order. The bathtub water heating circuit 35 is a circuit that connects the hot water storage tank 28, the bath heat exchanger 33, the bathtub water heating pump 34, and the hot water storage tank 28 in order, and the bathtub 42 is connected to the other circuit of the bath heat exchanger 33. ing.

The bathtub water circulation circuit 41 is a circuit which connects the bathtub 42, the bathtub water pump 40 which conveys bathtub water, and the bath heat exchanger 33 in order. The bathtub water pouring circuit 39 is a circuit for pouring the water in the hot water storage tank 28 to the bathtub 42 via the bathtub water circulation circuit 41. In this circuit, a bath water mixing valve 36 for mixing hot water in the hot water storage tank 28 and tap water, temperature detecting means 37 for detecting the temperature of the pouring water, and bath water pouring for opening and closing the bath water pouring circuit 39. The hot water valve 38 is provided in order. The melting device 16 was provided in the bathtub water pouring circuit 39 on the downstream side of the bathtub water pouring valve 38 so as to be housed in the housing of the main body.

  The operation of heating the water stored in the hot water storage tank 28 by the heat pump unit 21 is as follows. The water in the hot water storage tank 28 is conveyed to the hot water supply heat exchanger 23 by the hot water supply water pump 29 and heated by the heat pump cycle operation. The hot water supply pump 29 controls the flow rate of the hot water supply circuit 30 so that the temperature of the hot water heated by the hot water supply heat exchanger 23 becomes a predetermined temperature.

  The filling of the bathtub 42 and the heating of the bathtub water are as follows. The bath water mixing valve 36 of the bath water pouring circuit 39 has a hot water and tap water so that the pouring temperature detected by the temperature detecting means 37 becomes a temperature preset by a remote controller or the like (not shown). Adjust the mixing ratio. The bathtub water having a predetermined temperature flows out into the bathtub 42 through the bathtub water pouring circuit 39 and the bathtub water circulation circuit 41 in this order. On the other hand, when the bathtub water in the bathtub 42 is heated, the hot water stored in the hot water storage tank 28 is conveyed to the bath heat exchanger 33 by the bathtub water heating pump 34, and the bathtub water conveyed from the bathtub water pump 40. Heat. Hot-water supply water whose temperature has been lowered by heating the bath water in the bath heat exchanger 33 flows into the interior from the lower part of the hot water storage tank 28.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user hot waters the bathtub 42, the remote controller or the like performs a hot water operation instruction operation. After the remote control operation, when the water adjusted by the bathtub water mixing valve 36 at a preset temperature controls the bathtub water pouring valve 38 from closed to open, it passes through the melting device 16 and the bathtub water circulation circuit 41. It flows out into the bathtub 42. When the water passes through the dissolving device 16, the inorganic compound dissolves in the water, so that the water in which the inorganic compound 11 is dissolved flows into the bathtub 42 simultaneously with the hot water operation in the bathtub 42.

  Although the melting device 16 is on the downstream side of the bathtub water pouring valve 38, when the bathtub water pouring valve 38 is controlled from opening to closing, a water hammer phenomenon occurs and is provided in the upstream circuit. The bathtub water mixing valve 36, the hot water storage tank 28, etc. give a water pressure load higher than the water pressure. By providing on the downstream side, the hydraulic load on the melting device 16 is not applied.

  As mentioned above, in this Embodiment, it was set as the hot-water supply apparatus provided with the bathtub water-pouring circuit and the bathtub water-pouring valve, and equipped with the bathtub water-pouring circuit in order of the bathtub water-pouring valve and the melting apparatus. Thereby, since the melting device is not affected by the water hammer phenomenon (water pressure increase in the bathtub water pouring circuit or the like) that occurs when hot water to the bathtub is stopped, the pressure resistance structure of the melting device can be simplified. Furthermore, since the water flow of the hot water to the bathtub is used, the water in which the inorganic compound is dissolved can be supplied to the bathtub at the same time as the hot water, thereby improving convenience.

  In the present invention, the melting device 16 is housed in the main body housing of the water heater and serves as a bathtub water pouring circuit 39. However, even if provided in the bathtub water circulation circuit 41, water in which the inorganic compound 11 is dissolved is supplied to the bathtub 42. I can do it. Although it is possible to provide in the bathtub water circulation circuit 41 outside the main body casing, the atmospheric temperature inside the main body casing is reduced by heat radiation from the hot water storage tank 28 even at a low outside temperature. Is always heated, so that heat insulation such as prevention of freezing of the melting device 16 is unnecessary or simplified.

Further, the melting device 16 is further provided with an open / close electromagnetic valve (not shown) on the downstream side of the bathtub water pouring valve 38, a water circuit that passes through the melting device 16 on the downstream side, and water that does not pass through the melting device 16. It is possible to select the quality of bathtub water according to the user's preference by preparing two systems of circuits and selecting whether or not inorganic compounds are dissolved by switching the flow path with an open / close solenoid valve by using a bathroom remote control etc. Become. The open / close solenoid valve may be a manual switching valve, and the user may manually switch from outside the main body. Further, when the hot water heater is a hot water storage type hot water heater, high temperature hot water is stored in the hot water storage tank, so that the equipment can be sterilized and sterilized by supplying the hot water to the compound dissolving apparatus. Further, since the residual chlorine dissolved in the water is reduced during storage, the main body is not a corrosion-resistant material, and inexpensive general-purpose parts can be used.

  In FIG. 11, the inlet and outlet of the melting device 16 are connected to a bathtub water pouring circuit 39. When the equivalent diameter d1 of the inorganic compound storage container 12 storing the inorganic compound 11 and the equivalent diameter d2 of the bathtub water pouring circuit 39 are set, in FIG. 11, each is determined to have a size that satisfies d1> d2.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Since the inorganic compound storage container 12 storing the inorganic compound 11 and the filtering means storage container 14 are provided for the water circuit 15, a pressure loss occurs when water passes through the dissolving device 16. When pressure loss occurs, the flow rate of water supplied to the bathtub 42 decreases. Here, assuming that the equivalent diameter d1 of the inorganic compound storage container 12 is such that d1> d2 with respect to the equivalent diameter d2 of the bathtub water pouring circuit 39, the average flow velocity u1 of the inorganic compound storage container 12 is the bath water. It becomes smaller than the average flow velocity u2 of the pouring circuit 39. Since the pressure loss of the fluid in the water circuit is proportional to the square of the average flow velocity of the fluid, an increase in the pressure loss when passing through the dissolving device 16 can be reduced.

  As mentioned above, in this Embodiment, the pressure by the water flow which passes an inorganic compound is made larger by making the equivalent diameter of an inorganic compound storage container larger than the equivalent diameter of the bathtub water pouring circuit which connects a dissolving device. Loss can be reduced and the hot water filling time for the bathtub can be completed quickly.

  As described above, the hot water supply apparatus according to the present invention improves the efficiency of dissolving inorganic compounds in water, leading to compactness, cost reduction, and improvement in operating efficiency. In addition to hot water storage hot water heaters, Can also be used.

Multiple irregularities on the Therefore, the relative contact surface area of the inorganic compound with water can be increased, and the dissolution efficiency of the inorganic compound in water can be further increased. can do.

  Thereby, while increasing the amount of the inorganic compound dissolved in water, it is possible to reduce the size and cost, and to reduce power consumption because it is a principle that does not require power.

It is possible to dissolve inorganic compounds in water based on the principle of substance diffusion (Fick's law), in which substances move due to the difference in dissolution concentration between water and inorganic compounds. The granular body with a gap has a void inside, so that the specific gravity is reduced, and it easily swings due to the water flow in the storage container.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a structural diagram of a melting apparatus according to the first embodiment of the present invention.

  In FIG. 1, an inorganic compound 11 is soluble in water and has a surface provided with a plurality of irregularities, which is accommodated in an inorganic compound storage container 12. By the irregularities provided on the surface, the inorganic compound 11 The specific surface area of the inorganic compound with respect to the water flow flowing in the storage container 12 can be increased.

  As a specific means for obtaining the inorganic compound 11 having a plurality of irregularities on the surface, it is placed in a ball mill together with an inorganic compound having no irregularities on the surface and particles having a hardness higher than that of the inorganic compound and different specific gravity. Then, the inorganic compound which provided the unevenness | corrugation can be obtained by disperse | distributing in a solvent insoluble with respect to an inorganic compound, and carrying out specific gravity separation of an inorganic compound and particle | grains.

  In addition, an inorganic compound having an uneven fracture surface can be obtained by pulverizing an inorganic compound having no irregularities on the surface by applying a physical impact. The specific examples are merely examples, and are not limited as means for obtaining an inorganic compound having irregularities.

  When the inorganic compound 11 having a plurality of irregularities on the surface is filled in a multilayer shape, a porous space is formed in the inorganic compound storage container 12. The filtering means 13 has a plurality of small holes and is stored in the filtering means storage container 14. The inorganic compound storage container 12 and the filtration means storage container 14 are sequentially communicated by a water circuit 15, and the dissolution apparatus 16 is configured so that the inorganic compound storage container 12 is on the upstream side of the filtration means storage container 14.

  In addition, in the inorganic compound storage container 12, not only the inorganic compound 11 having irregularities on the surface but also powder particles of the inorganic compound 11 may be mixed.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while contacting the inorganic compound 11 having a plurality of irregularities on the surface filled in the inorganic compound storage container 12. Since water has viscosity, a velocity boundary layer is generated from the surface of the inorganic compound 11 to the region near the surface when passing through the porous space. FIG. 3 is a diagram showing the state of the velocity boundary layer. The flow velocity of the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the central portion of the porous space has a large distribution. Since the inorganic compound 11 is soluble in water, 11 surface molecules near the surface of the inorganic compound 11 are dissolved in water near the surface, and the dissolution concentration of water increases. Since the water near the surface has a low flow rate, the dissolved concentration has a high value.

  On the other hand, the dissolved concentration of water flowing in the center of the porous space having a high flow rate is low. At this time, if there is a difference in the concentration of the inorganic compound dissolved in water, the lower substance moves from the higher one according to the concentration difference (Fick's law), so the inorganic compound dissolved in the water near the surface Move to low center water. By utilizing this principle of substance diffusion, the inorganic compound 11 can be dissolved in water in the porous space.

  Furthermore, due to the plurality of irregularities formed on the surface of the inorganic compound, the contact surface area of the inorganic compound 11 with respect to water is several times or more than that without the irregularities, the dissolution concentration near the surface of the inorganic compound 11 is further increased, and the porous space The concentration difference from the central part of the water increases, and the amount of the inorganic compound 11 dissolved in water can be increased.

The action of increasing the dissolution efficiency of the inorganic compound 11 in water makes it possible not only to use the inorganic compound 11 having a low solubility in water, but also to reduce the filling amount of the inorganic compound 11 into the dissolution apparatus 16. The cost reduction by this can also be measured.
The filtering means 13 prevents the granules of the inorganic compound 11 from flowing out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12.

  As described above, in the present embodiment, the water circuit, the storage means for storing the inorganic compound having a plurality of projections and depressions on the surface, and the filtering means, the water flowing through the water circuit is stored in the storage means. The stored inorganic compound was dissolved, and a hot water supply apparatus provided with a dissolving device configured such that the dissolved inorganic compound passed through the filtering means was obtained.

  This makes it possible to increase the dissolution efficiency of the inorganic compound in water using the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in the dissolved concentration between water and the inorganic compound. Therefore, it is possible to provide a hot water supply apparatus that improves the melting characteristics of inorganic compounds, is compact, lowers cost, and further reduces power consumption while reducing power supply circuits and insulation circuits that have been required.

  In the present embodiment, the direction of the water flow with respect to the inorganic compound storage container 12 in the figure is an upward flow, but the flow direction is not limited, and the downward direction (FIG. 2) and the lateral direction are not limited. It is also possible to arrange. For example, when the flow direction is set to the upward direction, the particles of the inorganic compound 11 clogged in the filtering means 13 after the water flow is stopped are easily separated from the filtering means 13 by gravity drop, and the aging of the filtering means 13 is improved. It becomes possible to suppress clogging.

  In addition, when the inorganic compound is a zinc compound containing zinc (such as zinc oxide or zinc carbonate), the following effects can be obtained. Zinc is one of the essential elements of humans with relatively large demands, and is easily deficient when supplied from a normal diet. It is an element added to foods for the purpose of enhancing nutrition. On the other hand, the nutrition enhancement by percutaneous absorption can be performed during bathing by supplying water in which zinc is dissolved in the bathtub.

  In addition, zinc oxide, a zinc compound, is a material that has been approved under the pharmacopoeia and cosmetic raw material standards. It mainly has effects on the stratum corneum of human skin, such as astringent action and anti-inflammatory action, and the skin corners. Layer improvements can also be made.

  FIG. 4 is an example showing the relationship between the dimensions of the inorganic compound 11 and the filtering means 13 of the dissolving apparatus. In FIG. 4, the filtering means 13 is composed of a plurality of small holes 13a, 13b, 13c having different diameters.

  FIG. 5 is a configuration example of the filtering means 13. (A) forms a square-shaped small hole with a linear fiber. (B) is a plate having a predetermined thickness and small holes having a plurality of types of diameters. (C) forms a porous space by using a granular non-dissolving material as a multilayer. In any case, when the granules of the inorganic compound 11 are about to flow out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12, this is prevented, but the configuration and shape are not limited thereto.

  The dissolution concentration flowing out of the dissolution apparatus 16 is determined by the flow rate of water passing through the inorganic compound storage container 12, the surface area of the inorganic compound 11 in contact with water, and the like. When the dissolution concentration of the dissolution apparatus 16 is set to a predetermined value, the total surface area of the inorganic compound 11 needs to be within a certain range, so the particle size of the inorganic compound 11 stored in the inorganic compound storage container 12 of FIG. It is necessary to use the one selected for the size within the range.

  Since the selection causes a cost increase, among the inorganic compounds 11 having a plurality of diameters, the diameter D2 of the small hole 13a of the filtering means 13 is D2 <with respect to the maximum particle diameter D1 of the inorganic compound 11. In the case of D1, the following effects can be obtained. The inorganic compound 11 having a particle size less than D2 flows out from the small holes 13a, 13b, and 13c. In the initial stage of use, those having a small particle size flow out of the melting device 16, but after a predetermined time has passed, the inorganic compound 11 having a particle size of D2 or more continues to be stored in the inorganic compound storage container 12. When this state is formed, it is equivalent to selecting the particle size of the inorganic compound 11 to a size within a certain range. Therefore, even if the inorganic compound 11 in which the sizes are mixed is used, the target concentration is dissolved in water.

FIG. 6 shows a structural diagram of a melting apparatus according to the second embodiment of the present invention. In addition, about the same structure as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In FIG. 6, the inorganic compound 11 is a granular body 11 a obtained by combining a plurality of powder particles, or a mixture of the powder particles 11 b and the granular body 11 a, and is stored in the inorganic compound storage container 12.

  FIG. 7 shows an enlarged view of the granular inorganic compound. The granular material 11a of the inorganic compound 11 is formed by adhering the powder particles 11b of the inorganic compound through bonding means such as a binder to form a bonded body having a predetermined size and shape.

  As specific manufacturing means of the granular body 11a, a general-purpose manufacturing means such as a granulator is used to form the granular body 11a having a desired size and shape, and then heat treatment such as baking is performed in a subsequent process. Thus, the binding force of the binder between the granular bodies 11a can be increased, and the granular body 11a having a certain strength or more can be obtained.

  The shape of the granular body 11a is not particularly limited to a shape such as a substantially spherical shape, a substantially cubic shape, or a substantially rectangular parallelepiped shape. For example, in the case of a substantially spherical shape, the substantially spherical granular shape is placed in the inorganic compound storage container 12. By filling in multiple layers, the granular body 11a is placed in point contact with the adjacent granular body 11a, forming a gap that becomes a water passage between the granular bodies 11a, and inorganic. The pressure loss of the water flow in the compound storage container 12 can be reduced.

  Further, as described above, since the granular body 11a is a product in which a plurality of powder particles 11b of the inorganic compound 11 are combined in a substantially spherical shape, the surface of the granular body 11a is shown in FIG. As described above, at least an uneven portion 11c having an opening diameter equivalent to the diameter of the powder particle 11b and a depth equivalent to the same radius is formed, and the specific surface area with respect to water contacting the granular body 11a has no uneven portion. It will increase compared to the state of.

  Moreover, since the granular body 11a forms several space | gap inside the granular body 11a when couple | bonding the powder grain 11b, compared with the non-granular body of the same volume, specific gravity becomes small. For this reason, as shown in FIG. 5, when water flows into the inorganic compound storage container 12, the granular body 11 a has a small specific gravity, so that it swings randomly in the inorganic compound storage container 12 and is adjacent. The distance between the granular bodies 11a is larger than when the water flow is stopped.

  The granular body 11a of the inorganic compound 11 filled in the inorganic compound storage container 12 may be filled with the same diameter or a mixture of a plurality of spherical diameters. This eliminates the need for sieving the granule diameter, so that the cost can be kept low. Moreover, the uneven | corrugated size formed in the surface of the granular body 11a can also be adjusted arbitrarily by increasing / decreasing the particle diameter of the powder grain 11b of the inorganic compound 11. FIG.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while being in contact with the granular material 11a and the powder particles 11b of the inorganic compound 11 filled in the inorganic compound storage container 12.

The granular body 11a of the inorganic compound 11 in the inorganic compound storage container 12 receives the kinetic energy of the water flow, swings in the container, and maintains a state where the distance between the adjacent granular bodies 11a is expanded. Water flows between the granular bodies 11a. As described in the first embodiment, the inorganic compound 11 dissolves the inorganic compound 11 in water in which the lower substance moves from the higher one according to the concentration difference between the compound surface and flowing water (Fick's law). Can be
In the present embodiment, the granular body 11a swings to increase the distance from the center of the water, and the concentration difference between the inorganic compound surface and water becomes larger. The amount dissolved in water can be increased.

  As described above, in the present embodiment, the granular material 11a in which the plurality of powder particles 11b of the inorganic compound 11 are combined, or the mixture of the powder particles 11b and the granular material 11a is used as an inorganic compound storage container. 12, the inorganic compound 11 of the granular body 11a is a dissolving device provided with a plurality of irregularities 11c on the surface of the granules.

  As a result, the inorganic compound can be dissolved in water based on the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in dissolution concentration between water and the inorganic compound. The granular body 11a to which the particles 11b are bonded has a void in the interior, so that the specific gravity is lightened, easily swings due to the water flow in the inorganic compound storage container 12, and the surface of the granular body 11a is a powder. Since there are a plurality of irregularities 11c composed of the grains 11b, the effect of the rocking and irregularities increases the contact efficiency with water, and the dissolution efficiency of the inorganic compound in water can be further increased.

(Embodiment 3)
FIG. 8 shows a structural diagram of a melting apparatus according to the third embodiment of the present invention. FIG. 9 shows a plurality of shape examples of the inorganic compound molded body. In addition, about the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Reference numeral 17 denotes an inorganic compound molded body obtained by molding and solidifying the powder particles 11b of the inorganic compound 11 into a predetermined shape.

  As a specific manufacturing method of the inorganic compound molded body 17, powder particles 11 b of the inorganic compound 11, a binder component, and a solvent such as pure water are kneaded and formed into a predetermined shape using a mold, and then fired, etc. By performing the heat treatment in a subsequent process, the binding strength of the binder is increased and the strength as a molded body is ensured.

  In addition, the external dimension of the inorganic compound molded body 17 of this Embodiment is formed larger than the projection diameter with respect to the inorganic compound molded body 17 of the water circuit 15 connected to the inorganic compound storage container 12, and the inorganic compound storage container 12 is formed. When the water flows, the inorganic compound molded body 17 can prevent the downstream water circuit 15 from flowing out, so that it is not necessary to mount the filtering means 13 and the filtering means storage container 14 in the dissolving device 16. Not only can the construction cost of the melting device 16 be further reduced, but it is also possible to drastically remove the risk of quality degradation such as a reduction in the flow rate of the water circuit due to clogging of the filtering means 13.

  In addition, since the inorganic compound molded body 17 is a product obtained by molding the powder particles 11b, the surface of the granular body 11a has at least the diameter of the powder particles 11b as in the granular body 11a of the first embodiment. The uneven part 11c having the same opening diameter and the same depth as the radius is formed, and the specific surface area with respect to the water contacting the granular body 11a is increased as compared with the state without the uneven part.

  In addition, the inorganic compound molded body 17 can be formed in an arbitrary shape by using a molding die, and as shown in FIG. The contact area is increased to increase the dissolution efficiency of the inorganic compound 11 in water, and as shown in FIG. 7 (b), not only the contact area against water is increased, but also water is formed. Since resistance to the flow can be lowered, as shown in FIG. 8B, a plurality of honeycomb-shaped inorganic compound molded bodies 17 can be stacked and mounted on the inorganic compound storage container 12.

  As described above, in the present embodiment, since the outer dimension of the inorganic compound molded body 17 is larger than the inner diameter of the pipe of the water circuit 15 connected to the inorganic compound storage container 12, the water flow in the water circuit 15 Since the entire inorganic compound molded body 17 cannot flow out to the water circuit 15 by riding, it is not necessary to install a holding means such as a filtering means for holding the inorganic compound molded body 17 in the inorganic compound storage container 12, and the inorganic compound stored The construction cost of the container 12 can be reduced, and the surface of the inorganic compound molded body 17 is provided with a plurality of irregularities 11c. Therefore, the relative contact surface area of the inorganic compound molded body 17 with respect to water increases, and the water The cost can be further reduced while stabilizing the amount of the inorganic compound dissolved at a high level.

(Embodiment 4)
FIG. 10 shows a configuration diagram of a hot water supply apparatus according to the fourth embodiment of the present invention.

  In FIG. 10, a compressor 22, a hot water supply heat exchanger 23, a decompression unit 24, and an evaporator 25 are annularly connected in order by a refrigerant circuit 26 to constitute a heat pump unit 21. Water is stored in a hot water storage tank 28 of the hot water storage unit 27, and a hot water discharge circuit 30 is a circuit that connects the hot water storage tank 28, a hot water supply pump 29, a hot water supply heat exchanger 23, and a hot water storage tank 28 in this order. The bathtub water heating circuit 35 is a circuit that connects the hot water storage tank 28, the bath heat exchanger 33, the bathtub water heating pump 34, and the hot water storage tank 28 in order, and the bathtub 42 is connected to the other circuit of the bath heat exchanger 33. ing.

  The bathtub water circulation circuit 41 is a circuit which connects the bathtub 42, the bathtub water pump 40 which conveys bathtub water, and the bath heat exchanger 33 in order. The bathtub water pouring circuit 39 is a circuit for pouring the water in the hot water storage tank 28 to the bathtub 42 via the bathtub water circulation circuit 41. In this circuit, a bath water mixing valve 36 for mixing hot water in the hot water storage tank 28 and tap water, temperature detecting means 37 for detecting the temperature of the pouring water, and bath water pouring for opening and closing the bath water pouring circuit 39. The hot water valve 38 is provided in order. The melting device 16 was provided in the bathtub water pouring circuit 39 on the downstream side of the bathtub water pouring valve 38 so as to be housed in the housing of the main body.

  The operation of heating the water stored in the hot water storage tank 28 by the heat pump unit 21 is as follows. The water in the hot water storage tank 28 is conveyed to the hot water supply heat exchanger 23 by the hot water supply water pump 29 and heated by the heat pump cycle operation. The hot water supply pump 29 controls the flow rate of the hot water supply circuit 30 so that the temperature of the hot water heated by the hot water supply heat exchanger 23 becomes a predetermined temperature.

  The filling of the bathtub 42 and the heating of the bathtub water are as follows. The bath water mixing valve 36 of the bath water pouring circuit 39 has a hot water and tap water so that the pouring temperature detected by the temperature detecting means 37 becomes a temperature preset by a remote controller or the like (not shown). Adjust the mixing ratio. The bathtub water having a predetermined temperature flows out into the bathtub 42 through the bathtub water pouring circuit 39 and the bathtub water circulation circuit 41 in this order. On the other hand, when the bathtub water in the bathtub 42 is heated, the hot water stored in the hot water storage tank 28 is conveyed to the bath heat exchanger 33 by the bathtub water heating pump 34, and the bathtub water conveyed from the bathtub water pump 40. Heat. Hot-water supply water whose temperature has been lowered by heating the bath water in the bath heat exchanger 33 flows into the interior from the lower part of the hot water storage tank 28.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user hot waters the bathtub 42, the remote controller or the like performs a hot water operation instruction operation. After the remote control operation, when the water adjusted by the bathtub water mixing valve 36 at a preset temperature controls the bathtub water pouring valve 38 from closed to open, it passes through the melting device 16 and the bathtub water circulation circuit 41. It flows out into the bathtub 42. When the water passes through the dissolving device 16, the inorganic compound dissolves in the water, so that the water in which the inorganic compound 11 is dissolved flows into the bathtub 42 simultaneously with the hot water operation in the bathtub 42.

  Although the melting device 16 is on the downstream side of the bathtub water pouring valve 38, when the bathtub water pouring valve 38 is controlled from opening to closing, a water hammer phenomenon occurs and is provided in the upstream circuit. The bathtub water mixing valve 36, the hot water storage tank 28, etc. give a water pressure load higher than the water pressure. By providing on the downstream side, the hydraulic load on the melting device 16 is not applied.

  As mentioned above, in this Embodiment, it was set as the hot-water supply apparatus provided with the bathtub water-pouring circuit and the bathtub water-pouring valve, and equipped with the bathtub water-pouring circuit in order of the bathtub water-pouring valve and the melting apparatus. Thereby, since the melting device is not affected by the water hammer phenomenon (water pressure increase in the bathtub water pouring circuit or the like) that occurs when hot water to the bathtub is stopped, the pressure resistance structure of the melting device can be simplified. Furthermore, since the water flow of the hot water to the bathtub is used, the water in which the inorganic compound is dissolved can be supplied to the bathtub at the same time as the hot water, thereby improving convenience.

  In the present invention, the melting device 16 is housed in the main body housing of the water heater and serves as a bathtub water pouring circuit 39. However, even if provided in the bathtub water circulation circuit 41, water in which the inorganic compound 11 is dissolved is supplied to the bathtub 42. I can do it. Although it is possible to provide in the bathtub water circulation circuit 41 outside the main body casing, the atmospheric temperature inside the main body casing is reduced by heat radiation from the hot water storage tank 28 even at a low outside temperature. Is always heated, so that heat insulation such as prevention of freezing of the melting device 16 is unnecessary or simplified.

  Further, the melting device 16 is further provided with an open / close electromagnetic valve (not shown) on the downstream side of the bathtub water pouring valve 38, a water circuit that passes through the melting device 16 on the downstream side, and water that does not pass through the melting device 16. It is possible to select the quality of bathtub water according to the user's preference by preparing two systems of circuits and selecting whether or not inorganic compounds are dissolved by switching the flow path with an open / close solenoid valve by using a bathroom remote control etc. Become. The open / close solenoid valve may be a manual switching valve, and the user may manually switch from outside the main body. Further, when the hot water heater is a hot water storage type hot water heater, high temperature hot water is stored in the hot water storage tank, so that the equipment can be sterilized and sterilized by supplying the hot water to the compound dissolving apparatus. Further, since the residual chlorine dissolved in the water is reduced during storage, the main body is not a corrosion-resistant material, and inexpensive general-purpose parts can be used.

FIG. 11 is a structural diagram of a melting apparatus according to the fifth embodiment of the present invention.

  In FIG. 11, the inlet and outlet of the melting device 16 are connected to a bathtub water pouring circuit 39. When the equivalent diameter d1 of the inorganic compound storage container 12 storing the inorganic compound 11 and the equivalent diameter d2 of the bathtub water pouring circuit 39 are set, in FIG. 11, each is determined to have a size that satisfies d1> d2.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Since the inorganic compound storage container 12 storing the inorganic compound 11 and the filtering means storage container 14 are provided for the water circuit 15, a pressure loss occurs when water passes through the dissolving device 16. When pressure loss occurs, the flow rate of water supplied to the bathtub 42 decreases. Here, assuming that the equivalent diameter d1 of the inorganic compound storage container 12 is such that d1> d2 with respect to the equivalent diameter d2 of the bathtub water pouring circuit 39, the average flow velocity u1 of the inorganic compound storage container 12 is the bath water. It becomes smaller than the average flow velocity u2 of the pouring circuit 39. Since the pressure loss of the fluid in the water circuit is proportional to the square of the average flow velocity of the fluid, an increase in the pressure loss when passing through the dissolving device 16 can be reduced.

  As mentioned above, in this Embodiment, the pressure by the water flow which passes an inorganic compound is made larger by making the equivalent diameter of an inorganic compound storage container larger than the equivalent diameter of the bathtub water pouring circuit which connects a dissolving device. Loss can be reduced and the hot water filling time for the bathtub can be completed quickly.

  As described above, the hot water supply apparatus according to the present invention improves the efficiency of dissolving inorganic compounds in water, leading to compactness, cost reduction, and improvement in operating efficiency. In addition to hot water storage hot water heaters, Can also be used.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a structural diagram of a melting apparatus according to the first embodiment of the present invention.

  In FIG. 1, an inorganic compound 11 is soluble in water and has a surface provided with a plurality of irregularities, which is accommodated in an inorganic compound storage container 12. By the irregularities provided on the surface, the inorganic compound 11 The specific surface area of the inorganic compound with respect to the water flow flowing in the storage container 12 can be increased.

  As a specific means for obtaining the inorganic compound 11 having a plurality of irregularities on the surface, it is placed in a ball mill together with an inorganic compound having no irregularities on the surface and particles having a hardness higher than that of the inorganic compound and different specific gravity. Then, the inorganic compound which provided the unevenness | corrugation can be obtained by disperse | distributing in a solvent insoluble with respect to an inorganic compound, and carrying out specific gravity separation of an inorganic compound and particle | grains.

  In addition, an inorganic compound having an uneven fracture surface can be obtained by pulverizing an inorganic compound having no irregularities on the surface by applying a physical impact. The specific examples are merely examples, and are not limited as means for obtaining an inorganic compound having irregularities.

  When the inorganic compound 11 having a plurality of irregularities on the surface is filled in a multilayer shape, a porous space is formed in the inorganic compound storage container 12. The filtering means 13 has a plurality of small holes and is stored in the filtering means storage container 14. The inorganic compound storage container 12 and the filtration means storage container 14 are sequentially communicated by a water circuit 15, and the dissolution apparatus 16 is configured so that the inorganic compound storage container 12 is on the upstream side of the filtration means storage container 14.

  In addition, in the inorganic compound storage container 12, not only the inorganic compound 11 having irregularities on the surface but also powder particles of the inorganic compound 11 may be mixed.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while contacting the inorganic compound 11 having a plurality of irregularities on the surface filled in the inorganic compound storage container 12. Since water has viscosity, a velocity boundary layer is generated from the surface of the inorganic compound 11 to the region near the surface when passing through the porous space. FIG. 3 is a diagram showing the state of the velocity boundary layer. The flow velocity of the velocity boundary layer near the surface of the inorganic compound 11 is small, and the flow velocity passing through the central portion of the porous space has a large distribution. Since the inorganic compound 11 is soluble in water, 11 surface molecules near the surface of the inorganic compound 11 are dissolved in water near the surface, and the dissolution concentration of water increases. Since the water near the surface has a low flow rate, the dissolved concentration has a high value.

  On the other hand, the dissolved concentration of water flowing in the center of the porous space having a high flow rate is low. At this time, if there is a difference in the concentration of the inorganic compound dissolved in water, the lower substance moves from the higher one according to the concentration difference (Fick's law), so the inorganic compound dissolved in the water near the surface Move to low center water. By utilizing this principle of substance diffusion, the inorganic compound 11 can be dissolved in water in the porous space.

  Furthermore, due to the plurality of irregularities formed on the surface of the inorganic compound, the contact surface area of the inorganic compound 11 with respect to water is several times or more than that without the irregularities, the dissolution concentration near the surface of the inorganic compound 11 is further increased, and the porous space The concentration difference from the central part of the water increases, and the amount of the inorganic compound 11 dissolved in water can be increased.

The action of increasing the dissolution efficiency of the inorganic compound 11 in water makes it possible not only to use the inorganic compound 11 having a low solubility in water, but also to reduce the filling amount of the inorganic compound 11 into the dissolution apparatus 16. The cost reduction by this can also be measured.
The filtering means 13 prevents the granules of the inorganic compound 11 from flowing out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12.

  As described above, in the present embodiment, the water circuit, the storage means for storing the inorganic compound having a plurality of projections and depressions on the surface, and the filtering means, the water flowing through the water circuit is stored in the storage means. The stored inorganic compound was dissolved, and a hot water supply apparatus provided with a dissolving device configured such that the dissolved inorganic compound passed through the filtering means was obtained.

  This makes it possible to increase the dissolution efficiency of the inorganic compound in water using the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in the dissolved concentration between water and the inorganic compound. Therefore, it is possible to provide a hot water supply apparatus that improves the melting characteristics of inorganic compounds, is compact, lowers cost, and further reduces power consumption while reducing power supply circuits and insulation circuits that have been required.

  In the present embodiment, the direction of the water flow with respect to the inorganic compound storage container 12 in the figure is an upward flow, but the flow direction is not limited, and the downward direction (FIG. 2) and the lateral direction are not limited. It is also possible to arrange. For example, when the flow direction is set to the upward direction, the particles of the inorganic compound 11 clogged in the filtering means 13 after the water flow is stopped are easily separated from the filtering means 13 by gravity drop, and the aging of the filtering means 13 is improved. It becomes possible to suppress clogging.

  In addition, when the inorganic compound is a zinc compound containing zinc (such as zinc oxide or zinc carbonate), the following effects can be obtained. Zinc is one of the essential elements of humans with relatively large demands, and is easily deficient when supplied from a normal diet. It is an element added to foods for the purpose of enhancing nutrition. On the other hand, the nutrition enhancement by percutaneous absorption can be performed during bathing by supplying water in which zinc is dissolved in the bathtub.

  In addition, zinc oxide, a zinc compound, is a material that has been approved under the pharmacopoeia and cosmetic raw material standards. It mainly has effects on the stratum corneum of human skin, such as astringent action and anti-inflammatory action, and the skin corners. Layer improvements can also be made.

  FIG. 4 is an example showing the relationship between the dimensions of the inorganic compound 11 and the filtering means 13 of the dissolving apparatus. In FIG. 4, the filtering means 13 is composed of a plurality of small holes 13a, 13b, 13c having different diameters.

  FIG. 5 is a configuration example of the filtering means 13. (A) forms a square-shaped small hole with a linear fiber. (B) is a plate having a predetermined thickness and small holes having a plurality of types of diameters. (C) forms a porous space by using a granular non-dissolving material as a multilayer. In any case, when the granules of the inorganic compound 11 are about to flow out of the inorganic compound storage container 12 due to the water flow in the inorganic compound storage container 12, this is prevented, but the configuration and shape are not limited thereto.

  The dissolution concentration flowing out of the dissolution apparatus 16 is determined by the flow rate of water passing through the inorganic compound storage container 12, the surface area of the inorganic compound 11 in contact with water, and the like. When the dissolution concentration of the dissolution apparatus 16 is set to a predetermined value, the total surface area of the inorganic compound 11 needs to be within a certain range, so the particle size of the inorganic compound 11 stored in the inorganic compound storage container 12 of FIG. It is necessary to use the one selected for the size within the range.

  Since the selection causes a cost increase, among the inorganic compounds 11 having a plurality of diameters, the diameter D2 of the small hole 13a of the filtering means 13 is D2 <with respect to the maximum particle diameter D1 of the inorganic compound 11. In the case of D1, the following effects can be obtained. The inorganic compound 11 having a particle size less than D2 flows out from the small holes 13a, 13b, and 13c. In the initial stage of use, those having a small particle size flow out of the melting device 16, but after a predetermined time has passed, the inorganic compound 11 having a particle size of D2 or more continues to be stored in the inorganic compound storage container 12. When this state is formed, it is equivalent to selecting the particle size of the inorganic compound 11 to a size within a certain range. Therefore, even if the inorganic compound 11 in which the sizes are mixed is used, the target concentration is dissolved in water.

(Embodiment 2)
FIG. 6 shows a structural diagram of a melting apparatus according to the second embodiment of the present invention. In addition, about the same structure as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In FIG. 6, the inorganic compound 11 is a granular body 11 a obtained by combining a plurality of powder particles, or a mixture of the powder particles 11 b and the granular body 11 a, and is stored in the inorganic compound storage container 12.

  FIG. 7 shows an enlarged view of the granular inorganic compound. The granular material 11a of the inorganic compound 11 is formed by adhering the powder particles 11b of the inorganic compound through bonding means such as a binder to form a bonded body having a predetermined size and shape.

  As specific manufacturing means of the granular body 11a, a general-purpose manufacturing means such as a granulator is used to form the granular body 11a having a desired size and shape, and then heat treatment such as baking is performed in a subsequent process. Thus, the binding force of the binder between the granular bodies 11a can be increased, and the granular body 11a having a certain strength or more can be obtained.

  The shape of the granular body 11a is not particularly limited to a shape such as a substantially spherical shape, a substantially cubic shape, or a substantially rectangular parallelepiped shape. For example, in the case of a substantially spherical shape, the substantially spherical granular shape is placed in the inorganic compound storage container 12. By filling in multiple layers, the granular body 11a is placed in point contact with the adjacent granular body 11a, forming a gap that becomes a water passage between the granular bodies 11a, and inorganic. The pressure loss of the water flow in the compound storage container 12 can be reduced.

  Further, as described above, since the granular body 11a is a product in which a plurality of powder particles 11b of the inorganic compound 11 are combined in a substantially spherical shape, the surface of the granular body 11a is shown in FIG. As described above, at least an uneven portion 11c having an opening diameter equivalent to the diameter of the powder particle 11b and a depth equivalent to the same radius is formed, and the specific surface area with respect to water contacting the granular body 11a has no uneven portion. It will increase compared to the state of.

  Moreover, since the granular body 11a forms several space | gap inside the granular body 11a when couple | bonding the powder grain 11b, compared with the non-granular body of the same volume, specific gravity becomes small. For this reason, as shown in FIG. 5, when water flows into the inorganic compound storage container 12, the granular body 11 a has a small specific gravity, so that it swings randomly in the inorganic compound storage container 12 and is adjacent. The distance between the granular bodies 11a is larger than when the water flow is stopped.

  The granular body 11a of the inorganic compound 11 filled in the inorganic compound storage container 12 may be filled with the same diameter or a mixture of a plurality of spherical diameters. This eliminates the need for sieving the granule diameter, so that the cost can be kept low. Moreover, the uneven | corrugated size formed in the surface of the granular body 11a can also be adjusted arbitrarily by increasing / decreasing the particle diameter of the powder grain 11b of the inorganic compound 11. FIG.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Water flowing from the water circuit 15 into the dissolving device 16 passes through the porous space while being in contact with the granular material 11a and the powder particles 11b of the inorganic compound 11 filled in the inorganic compound storage container 12.

The granular body 11a of the inorganic compound 11 in the inorganic compound storage container 12 receives the kinetic energy of the water flow, swings in the container, and maintains a state where the distance between the adjacent granular bodies 11a is expanded. Water flows between the granular bodies 11a. As described in the first embodiment, the inorganic compound 11 dissolves the inorganic compound 11 in water in which the lower substance moves from the higher one according to the concentration difference between the compound surface and flowing water (Fick's law). Can be
In the present embodiment, the granular body 11a swings to increase the distance from the center of the water, and the concentration difference between the inorganic compound surface and water becomes larger. The amount dissolved in water can be increased.

  As described above, in the present embodiment, the granular material 11a in which the plurality of powder particles 11b of the inorganic compound 11 are combined, or the mixture of the powder particles 11b and the granular material 11a is used as an inorganic compound storage container. 12, the inorganic compound 11 of the granular body 11a is a dissolving device provided with a plurality of irregularities 11c on the surface of the granules.

  As a result, the inorganic compound can be dissolved in water based on the principle of substance diffusion (Fick's law) in which the substance moves due to the difference in dissolution concentration between water and the inorganic compound. The granular body 11a to which the particles 11b are bonded has a void in the interior, so that the specific gravity is lightened, easily swings due to the water flow in the inorganic compound storage container 12, and the surface of the granular body 11a is a powder. Since there are a plurality of irregularities 11c composed of the grains 11b, the effect of the rocking and irregularities increases the contact efficiency with water, and the dissolution efficiency of the inorganic compound in water can be further increased.

(Embodiment 3)
FIG. 8 shows a structural diagram of a melting apparatus according to the third embodiment of the present invention. FIG. 9 shows a plurality of shape examples of the inorganic compound molded body. In addition, about the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Reference numeral 17 denotes an inorganic compound molded body obtained by molding and solidifying the powder particles 11b of the inorganic compound 11 into a predetermined shape.

  As a specific manufacturing method of the inorganic compound molded body 17, powder particles 11 b of the inorganic compound 11, a binder component, and a solvent such as pure water are kneaded and formed into a predetermined shape using a mold, and then fired, etc. By performing the heat treatment in a subsequent process, the binding strength of the binder is increased and the strength as a molded body is ensured.

  In addition, the external dimension of the inorganic compound molded body 17 of this Embodiment is formed larger than the projection diameter with respect to the inorganic compound molded body 17 of the water circuit 15 connected to the inorganic compound storage container 12, and the inorganic compound storage container 12 is formed. When the water flows, the inorganic compound molded body 17 can prevent the downstream water circuit 15 from flowing out, so that it is not necessary to mount the filtering means 13 and the filtering means storage container 14 in the dissolving device 16. Not only can the construction cost of the melting device 16 be further reduced, but it is also possible to drastically remove the risk of quality degradation such as a reduction in the flow rate of the water circuit due to clogging of the filtering means 13.

  In addition, since the inorganic compound molded body 17 is a product obtained by molding the powder particles 11b, the surface of the granular body 11a has at least the diameter of the powder particles 11b as in the granular body 11a of the first embodiment. The uneven part 11c having the same opening diameter and the same depth as the radius is formed, and the specific surface area with respect to the water contacting the granular body 11a is increased as compared with the state without the uneven part.

  In addition, the inorganic compound molded body 17 can be formed in an arbitrary shape by using a molding die, and as shown in FIG. The contact area is increased to increase the dissolution efficiency of the inorganic compound 11 in water, and as shown in FIG. 7 (b), not only the contact area against water is increased, but also water is formed. Since resistance to the flow can be lowered, as shown in FIG. 8B, a plurality of honeycomb-shaped inorganic compound molded bodies 17 can be stacked and mounted on the inorganic compound storage container 12.

As described above, in the present embodiment, since the outer dimension of the inorganic compound molded body 17 is larger than the inner diameter of the pipe of the water circuit 15 connected to the inorganic compound storage container 12, the water flow in the water circuit 15 Since the entire inorganic compound molded body 17 cannot flow out to the water circuit 15 by riding, it is not necessary to install a holding means such as a filtering means for holding the inorganic compound molded body 17 in the inorganic compound storage container 12, and the inorganic compound stored The construction cost of the container 12 can be reduced, and the surface of the inorganic compound molded body 17 is provided with a plurality of irregularities 11c. Therefore, the relative contact surface area of the inorganic compound molded body 17 with respect to water increases, and the water The cost can be further reduced while stabilizing the amount of the inorganic compound dissolved at a high level.

  The operation of heating the water stored in the hot water storage tank 28 by the heat pump unit 21 is as follows. The water in the hot water storage tank 28 is conveyed to the hot water supply heat exchanger 23 by the hot water supply water pump 29 and heated by the heat pump cycle operation. The hot water supply pump 29 controls the flow rate of the hot water supply circuit 30 so that the temperature of the hot water heated by the hot water supply heat exchanger 23 becomes a predetermined temperature.

On the other hand, when the bathtub water in the bathtub 42 is heated, the hot water stored in the hot water storage tank 28 is conveyed to the bath heat exchanger 33 by the bathtub water heating pump 34, and the bathtub water conveyed from the bathtub water pump 40. Heat. Hot-water supply water whose temperature has been lowered by heating the bath water in the bath heat exchanger 33 flows into the interior from the lower part of the hot water storage tank 28.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the user hot waters the bathtub 42, the remote controller or the like performs a hot water operation instruction operation. After the remote control operation, when the water adjusted by the bathtub water mixing valve 36 at a preset temperature controls the bathtub water pouring valve 38 from closed to open, it passes through the melting device 16 and the bathtub water circulation circuit 41. It flows out into the bathtub 42. When the water passes through the dissolving device 16, the inorganic compound dissolves in the water, so that the water in which the inorganic compound 11 is dissolved flows into the bathtub 42 simultaneously with the hot water operation in the bathtub 42.

Although the melting device 16 is on the downstream side of the bathtub water pouring valve 38, when the bathtub water pouring valve 38 is controlled from opening to closing, a water hammer phenomenon occurs and is provided in the upstream circuit. The bathtub water mixing valve 36, the hot water storage tank 28, etc. give a water pressure load higher than the water pressure. By providing on the downstream side, the hydraulic load on the melting device 16 is not applied.

  As mentioned above, in this Embodiment, it was set as the hot-water supply apparatus provided with the bathtub water-pouring circuit and the bathtub water-pouring valve, and equipped with the bathtub water-pouring circuit in order of the bathtub water-pouring valve and the melting apparatus. Thereby, since the melting device is not affected by the water hammer phenomenon (water pressure increase in the bathtub water pouring circuit or the like) that occurs when hot water to the bathtub is stopped, the pressure resistance structure of the melting device can be simplified. Furthermore, since the water flow of the hot water to the bathtub is used, the water in which the inorganic compound is dissolved can be supplied to the bathtub at the same time as the hot water, thereby improving convenience.

  In the present invention, the melting device 16 is housed in the main body housing of the water heater and serves as a bathtub water pouring circuit 39. However, even if provided in the bathtub water circulation circuit 41, water in which the inorganic compound 11 is dissolved is supplied to the bathtub 42. I can do it. Although it is possible to provide in the bathtub water circulation circuit 41 outside the main body casing, the atmospheric temperature inside the main body casing is reduced by heat radiation from the hot water storage tank 28 even at a low outside temperature. Is always heated, so that heat insulation such as prevention of freezing of the melting device 16 is unnecessary or simplified.

  Further, the melting device 16 is further provided with an open / close electromagnetic valve (not shown) on the downstream side of the bathtub water pouring valve 38, a water circuit that passes through the melting device 16 on the downstream side, and water that does not pass through the melting device 16. It is possible to select the quality of bathtub water according to the user's preference by preparing two systems of circuits and selecting whether or not inorganic compounds are dissolved by switching the flow path with an open / close solenoid valve by using a bathroom remote control etc. Become. The open / close solenoid valve may be a manual switching valve, and the user may manually switch from outside the main body. Further, when the hot water heater is a hot water storage type hot water heater, high temperature hot water is stored in the hot water storage tank, so that the equipment can be sterilized and sterilized by supplying the hot water to the compound dissolving apparatus. Further, since the residual chlorine dissolved in the water is reduced during storage, the main body is not a corrosion-resistant material, and inexpensive general-purpose parts can be used.

(Embodiment 5)
FIG. 11 is a structural diagram of a melting apparatus according to the fifth embodiment of the present invention.

  In FIG. 11, the inlet and outlet of the melting device 16 are connected to a bathtub water pouring circuit 39. When the equivalent diameter d1 of the inorganic compound storage container 12 storing the inorganic compound 11 and the equivalent diameter d2 of the bathtub water pouring circuit 39 are set, in FIG. 11, each is determined to have a size that satisfies d1> d2.

  About the hot water supply apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. Since the inorganic compound storage container 12 storing the inorganic compound 11 and the filtering means storage container 14 are provided for the water circuit 15, a pressure loss occurs when water passes through the dissolving device 16. When pressure loss occurs, the flow rate of water supplied to the bathtub 42 decreases. Here, assuming that the equivalent diameter d1 of the inorganic compound storage container 12 is such that d1> d2 with respect to the equivalent diameter d2 of the bathtub water pouring circuit 39, the average flow velocity u1 of the inorganic compound storage container 12 is the bath water. It becomes smaller than the average flow velocity u2 of the pouring circuit 39. Since the pressure loss of the fluid in the water circuit is proportional to the square of the average flow velocity of the fluid, an increase in the pressure loss when passing through the dissolving device 16 can be reduced.

  As mentioned above, in this Embodiment, the pressure by the water flow which passes an inorganic compound is made larger by making the equivalent diameter of an inorganic compound storage container larger than the equivalent diameter of the bathtub water pouring circuit which connects a dissolving device. Loss can be reduced and the hot water filling time for the bathtub can be completed quickly.

  As described above, the hot water supply apparatus according to the present invention improves the efficiency of dissolving inorganic compounds in water, leading to compactness, cost reduction, and improvement in operating efficiency. In addition to hot water storage hot water heaters, Can also be used.
