Description

  The present invention relates to a carbonated spring artificial hot spring apparatus mainly corresponding to commercial bathing facility machines.

  As a means of artificially creating carbonated springs, a method of using carbon dioxide gas to blow directly into hot water and dissolving carbon dioxide gas is often used. However, if carbon dioxide gas is dissolved directly in bath water, the hydrogen ion concentration in the bath water decreases. In particular, when a carbon dioxide-dissolved solution is generated outside the bathtub and supplied to the bathtub, the carbon dioxide gas is saturated, so the formation of a high-concentration carbonate spring is not possible. However, it must be carried out under a certain high pressure, and there are problems such as equipment cost and complicated maintenance.

  In addition, as a method for easily producing a high-concentration carbonated spring, a carbon dioxide-generating tablet (solid bathing agent) mainly composed of carbonate and acid is mixed in a bathtub or a bath water supply channel. (For example, JP-A-6-327740), when the solid bath agent dissolves, there is a portion where carbonate and acid are locally concentrated around the tablet, and the generation rate of carbon dioxide is high. As a result, the dissolution rate of carbon dioxide gas cannot catch up with the generation rate of carbon dioxide gas, and a part of the generated carbon dioxide gas cannot be dissolved and diffuses into the air, and the generated carbon dioxide gas is not used effectively. There is a problem.

  As a countermeasure, Patent Document 1 (Japanese Patent Laid-Open No. 11-19167) discloses a bath salt supply device in which a carbonate supply unit and an acid supply unit are provided independently in a hot water supply path, respectively, and carbonate dissolved hot water is provided. A means for generating carbon dioxide gas by reacting water with acid-dissolved hot water is disclosed.

  Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2006-22021), an alkali carbonate is directly or made into an aqueous solution and directly poured into a bath water (tub), the bath water is made into an alkali carbonate spring state, and an acid component is made into an aqueous solution. In addition, a hot spring apparatus is disclosed in which, if necessary, it is circulated and heated, poured into bath water (a bathtub), and carbon dioxide is generated by a reaction in the bathtub.

Japanese Patent Application Laid-Open No. 11-19167. Japanese Patent Laid-Open No. 2006-22021.

  The means for generating carbon dioxide gas by the reaction of alkali carbonate and acid component to form an artificial carbonated spring is known as described above, but the hot spring device disclosed in Patent Document 1 is premised on a solution by contact with alkali carbonate. Therefore, there is a limit to the generation of high-concentration carbon dioxide gas, and since it is intended for shower hot water supply and mist shower, it is not suitable for commercial artificial hot spring equipment.

  Further, in the apparatus disclosed in Patent Document 2, since the carbon dioxide gas is generated by the charging control of the acid component solution in a state where the alkali carbonate is charged in the bath water in the bathtub, the hot spring component is not necessarily constant. It is not something that is kept. In addition, when trying to adopt an artificial composite spring that contains other hot spring components of carbon dioxide, there is insufficient generation of carbon dioxide due to the reaction of alkali carbonate in the bath with other hot spring components, and the residual reaction of acid components. There is a risk that the hot spring component of the bath water is not flexible and the hot spring component of the bath water is kept constant.

  Therefore, the present invention has proposed a novel artificial hot spring apparatus that can flexibly cope with a wide variety of complex carbonated springs, can keep the hot spring components of the hot springs constant, and can easily maintain the hot spring components. Is.

  An artificial hot spring apparatus according to the present invention includes a bathtub having an appropriate capacity, a heating hot water supply unit having a heating mechanism for supplying hot water to the bathtub, a circulation heating unit for circulating and heating the hot water in the bathtub, and heating. A hot water supply unit, a circulating heating unit, and a bathtub are provided between the hot water supply unit and the circulating heating unit so that hot water from the hot water supply unit and the circulating heating unit pass through the bath. And a first chemical solution supply unit for supplying alkaline carbonate-containing water to the mixing channel unit, and a chemical solution tank having a stirring mechanism for mixing with the chemical solution tank, and a discharge pump and a discharge opening / closing valve attached to the chemical solution tank. A chemical tank for storing an aqueous solution of an acid component that reacts with an alkali carbonate to generate carbon dioxide, a discharge pump and an on-off valve attached to the chemical tank, The amount of hot water from the second chemical liquid supply unit for supplying Corresponding to the amount of carbon dioxide gas decrease in the circulating hot water of the ring heating unit, an operation control unit for controlling the supply amount of alkali carbonate-containing water and acid component-containing water from the first chemical part and the second chemical part is provided. It is characterized by.

  Thus, when bath water is supplied to the bathtub, when hot water of a predetermined temperature passes through the mixing channel section, the hot water supply set in advance with the alkali carbonate-containing water and the acid component-containing water simultaneously or after a certain time interval. When a predetermined amount corresponding to the amount is added and mixed and supplied to the bathtub, the alkali carbonate-containing water and the acid component-containing water react in the bathtub to generate carbon dioxide, and the bath water becomes carbonated spring.

  When circulating the bath water, when the carbon dioxide concentration of the circulating bath is below a predetermined level (based on the predicted concentration when there is no sensor), a predetermined amount of chemical solution is supplied at a predetermined timing, This bath water maintains a predetermined bath temperature and carbon dioxide gas concentration.

  In this way, the chemical solutions (alkali carbonate-containing water and acid component-containing water) in the first chemical solution supply unit and the second chemical solution supply unit in particular correspond to the hot water supply amount of the heated hot water supply unit, the hot water amount of the circulating hot water, and the carbon dioxide gas concentration. The hot spring quality maintenance control of the bath water in the bathtub can be easily performed.

  Further, in the present invention (Claim 3), when the chemical solution tank of the first chemical solution part has a sealed structure and the discharge pump is an air pump that increases the internal pressure of the chemical solution tank, the water solubility of the alkali carbonate is low. However, the solid content can be supplied to the mixing channel portion, and the alkali carbonate-containing concentration of the alkali carbonate-containing water can be set as desired.

  In addition, the present invention (Claim 4) is provided with a stirring mechanism for mixing the chemical solution and water of the desired hot spring component, and provided with a discharge pump and an on-off valve to supply the desired chemical solution-containing water to the mixing channel section. A third chemical solution supply unit is added, and products based on the reaction of alkali carbonates and acid components (other than carbon dioxide) become complex carbonated springs instead of simple carbonated springs. In the case of including an artificial hot spring, a desired composite carbonated spring can be obtained by supplying hot spring components by the third chemical solution supply unit.

  Since the present invention has the above-described configuration, it is possible to provide a commercial hot spring apparatus for carbonated springs that can be easily controlled and can maintain a certain quality of hot spring.

  Next, an embodiment of the present invention will be described. The artificial hot spring apparatus shown in the embodiment includes a bathtub section 1, a heated hot water supply section 2, a mixing flow path section 3, a circulation heating section 4, a first chemical liquid supply section 5, and a second chemical liquid supply section 6. The third subcomponent supply unit 7 and a control unit that instructs operation control of each unit are configured.

  The bathtub portion 1 includes a bathtub 11 having a predetermined size, and the bathtub 11 includes a sensor portion (a water level sensor, a hot water temperature sensor, a carbonic acid concentration sensor) 12, and the water level sensor is a bath water in the bathtub 11. It is possible to detect that the water level is lower than the minimum water level of A, and the hot water temperature sensor may detect the temperature below the minimum set temperature and the temperature above the maximum set temperature. Bathtub hot water) It detects the amount of carbon dioxide generated from A, and may detect a predetermined value or less.

  As will be described later, the water level sensor is not required when the operation amount of the heated hot water supply unit 2 is set in advance and the hot water supply amount to the bathtub 1 is always sufficient and the overflow state is maintained. Further, the carbon dioxide sensor is not required when the operation control of each of the chemical solution supply units 5, 6, and 7 is set by a predetermined time supply.

  The heating hot water supply unit 2 supplies a boiler 21, a water supply unit (water supply opening / closing valve 22) for supplying water to the boiler, and hot water A 1 having a predetermined temperature to the mixing channel unit 3, and a heat exchange unit of the circulation heating unit 4 described later. A hot water supply pump 23 for supplying heat as a heat source to 41, and a hot water on / off valve 24 and a flow meter 25 for confirming the amount of hot water are interposed between the hot water supply pump 23 and the mixing flow path section 3. It will be. In addition, an on-off valve 26 is interposed in the hot water supply path to the heat exchange unit 41 of the circulating heating unit 4.

  The mixing flow path portion 3 receives hot water A1 from the heated hot water supply portion 2 and circulating hot water A2 from the circulating heating portion described later, and supplies chemical liquids B, C, and D from the chemical liquid supply portions 5, 6, and 7, respectively. The hot spring water A is mixed by flowing them and supplied into the bathtub 11.

  The circulation part heating part 4 includes a drawing pipe 42 from the bottom of the bathtub 11, a strainer 43, a circulation pump 44, a filter 46 provided with a backwash mechanism 45, and a heat exchange part 41 for heating the circulating bath water A2. And the circulating bath is configured by supplying the circulating bath water A2 from the heat exchanging section 41 to the mixing channel section 2.

  The backwashing mechanism 45 is used to remove precipitates from the chemical solution in the third chemical solution supply unit 7 and precipitates generated by the reaction between the alkali carbonate and the acid component with the filter 46. In order to eliminate clogging, flush water is poured from the opposite direction and discharged out of the circulation path.

  The first chemical solution supply unit 5, the second chemical solution supply unit 6, and the third chemical solution supply unit 7 (illustration of the internal configuration is omitted) are basically the same configuration, and the chemical solution in which the stirring mechanisms 51 and 61 are provided. Tanks 52 and 62, discharge pumps 53 and 63 attached to the chemical liquid tanks 52 and 62, discharge opening and closing valves 54 and 64, supply units 55 and 65 for supplying predetermined chemical liquids to the chemical liquid tanks 52 and 62, and chemical liquids Water supply valves 56 and 66 for supplying water (or hot water) to the tanks 52 and 62 are provided.

  Then, a predetermined amount of water is supplied to the chemical tanks 52 and 62 by opening the water supply valves 56 and 66. In the first chemical supply section 5, an alkali carbonate (sodium bicarbonate, sodium sesquicarbonate, Sodium carbonate, etc.) is stored and supplied into the chemical solution tank 52, and these are stirred to prepare and store the alkali carbonate-containing water B containing or not containing solid matter that is not dissolved. When the operation and the release on / off valve 54 are opened, a predetermined amount of the alkali carbonate-containing water B is discharged into the mixing channel section 3.

  Similarly, in the second chemical solution supply unit 6, the supply unit 65 stores powder of an acid component (citric acid, tartaric acid, malic acid, boric acid) or an acid component solution, and supplies an appropriate amount to the chemical solution tank 62. The mixture is stirred and stored as an acid component aqueous solution (acid component-containing water) C, and a predetermined amount of acid component-containing water is added to the mixing flow path portion 3 by operating the discharge pump 63 and opening the discharge on-off valve 64. C is released. The same applies to the third chemical liquid supply unit 7, and the chemical liquid is arbitrarily determined according to the demand for what kind of hot spring water A is to be used.

  In particular, the first chemical solution supply unit 5 does not always have the alkali carbonate dissolved in the alkali carbonate-containing water B. Therefore, the chemical solution tank 52 has a sealed structure, and the discharge pump 53 is connected to the chemical solution tank 52. An air pump that raises the internal pressure is set so as not to cause clogging of the pump due to the solid content of the alkali carbonate-containing water B during discharge.

  A control part controls operation of each above-mentioned part uniformly, operation of heating hot water supply part 2 based on a detection value of a water level sensor, amount of hot water supply of hot water A1 from heating supply part 2 (it can be checked with flow meter 45) The amount of discharge of each chemical solution section 5, 6 and 7 and the timing thereof, the operation of the circulating heating section 4 based on the temperature sensor and the carbonic acid concentration sensor, the hot water supply amount (operation time) of hot water A2 from the circulating heating section 4 and the circulating hot water A2 The discharge amount and timing of each of the chemical liquid parts 5, 6, and 7 with respect to the carbonic acid concentration are set.

  Thus, the operation of each part when the heated hot water supply part 2 is operated will be described. When the water supply valve 22 is opened and supplied to the boiler 21, it is heated to a predetermined temperature to be hot water A 1, and is supplied to the bathtub 11 through the mixing channel portion 3 by the operation of the hot water supply pump 23.

  And in the mixing flow path part 3, each chemical | medical solution part 5,6,7 is operated, a predetermined chemical | medical solution is added and mixed with the hot water A1, and especially the alkali carbonate containing water B is supplied from the 1st chemical | medical solution supply part 5. The acid component-containing water C is added and mixed from the second chemical solution supply unit 6.

  The chemical solution mixed water A flows into the bathtub 11 as it is, and carbon dioxide gas is generated in the hot water (tub water) A by a chemical reaction caused by contact between the alkali carbonate-containing water B and the acid component-containing water C. The hot water is a carbonated spring.

  Therefore, the hot water supply section 2 is operated to supply carbonated hot water A to the bathtub 11 at the initial operation of the artificial hot spring apparatus, when the bathtub water level is lowered by the water level detection by the water level sensor, or at regular intervals.

  Next, the operation of the circulating heating unit 4 will be described. The circulation heating unit 4 corresponds to the temperature drop of the bath 11 bath water or the carbon dioxide gas concentration, and is operated based on the detection value of the temperature sensor or the detection value of the carbon dioxide gas concentration sensor, or operates on a regular basis. It is something to be made.

  The operation of the circulating heating unit 4 is performed by operating a circulating pump 44 to draw out a certain amount of bath water, filtering a large amount of dust with a strainer 43, and further removing fine dust with a filter 46. It is heated and heated to a predetermined temperature to form circulating hot water A2, which is then fed into the mixing channel section 3.

  In the mixing flow path section 3, the chemical liquid supply sections 5, 6, and 7 are operated in the same manner as the hot water supply A <b> 1, and a predetermined chemical liquid is added to and mixed with the hot water A <b> 2 and supplied to the bathtub 11 as carbonated hot water A. Is. Of course, the circulation heating unit 4 may be operated at all times, and the chemical solution supply units 5, 6, and 7 may be operated intermittently.

  In the circulation operation, the hot water supply pump 23 of the heating hot water supply unit 4 is operated and the on-off valve 26 is opened to heat the hot water from the boiler 21 to the heat exchange unit 41 in order to heat the circulating bath water A2. Supply and raise temperature of circulating hot water A2. In addition, when the circulation operation is not performed, the backwashing mechanism 45 is appropriately operated to clean the filter of the filter 46.

  Therefore, even if the temperature of the bath water A in the bathtub 11 is lowered or the carbon dioxide gas concentration is lowered, the temperature of the bath water A and the carbon dioxide gas concentration can be maintained within a certain range by the operation of the circulating heating unit 4. .

  Furthermore, by selecting an alkali carbonate or an acid component, it is possible to easily obtain not only a simple carbonated hot spring but also a complex carbonated spring containing various hot spring components by a reaction product generated simultaneously with the generation of carbon dioxide gas by the chemical reaction. In addition, an artificial carbonated spring containing arbitrarily various hot spring components can be obtained by adding a third chemical solution supply unit.
