Description

The present invention can regenerate industrial elements such as a thread-wound filter that can separate dust from the time when bathing of hot water in a relatively low temperature and slightly high temperature bath is completed, and the filter itself. It is air from a ceramic membrane filter that can regenerate and filter the hot water after filtration to the extent required by the Waterworks Law via an ultra-fine filtration device with a ceramic membrane filter that can also remove viruses. A second tank for forming the hot water after filtration between the central tank of the hot water storage tank of the present invention and the outside thereof, by eliminating the destruction of the filter by storing in the back filter such as dust and bacteria by washing, and further By inserting a heat insulating material such as glass wool and a reflective composite material such as aluminum foil into two gaps between the outer periphery and the third tank, the energy to the atmosphere is reduced. Endured release for use in the long term to prevent a radiation-heat transfer, is to St. provide an apparatus for the cost reduction and CO2 measures.

  Conventionally, when bathing in a bathtub, when bathing by a large number of people, because of the addition of hot water and hot water in the middle, generally in the late-night electric water heater and eco-cute that heat tap water, the quantitative problem is, Responding to the expansion of tank capacity, the hot water problem is dealt with by adding an external heat exchange function, etc., but in order to increase user satisfaction, an increase in selling prices is unavoidable. Energy and the use of expensive daytime electricity tend to be needed, and the second midnight power, which is cheaper than electricity, is 5 hours from 1 am to 6 am for Chubu Electric Power. If the electric power is used only in the time zone, there will be a large shift in the usage time of 12 hours or more after 6 pm, which is actually the usage time zone of the bath.

  Various techniques are necessary to keep the heat-retaining state well until this time of use, and generally, a method of keeping the container part warm by wrapping the container part with vacuum heat insulating material or glass wool is taken, For example, the patent application for the hot water tank disclosed in Japanese Patent Application Laid-Open No. 2001-116367, which is covered with a heat insulating material around the tank, and the Ecocute and midnight electric water heaters currently on sale, are this method. Is heated from the inside and hot water is accumulated in the upper part, so that the hot water is discharged from the upper side. From the standpoint of preventing heat dissipation from radiating heat from the outer periphery of the tank and preventing convection, the structure is insufficient even in terms of cost, and the structure is not suitable for long-term heat retention.

  In general, late-night electric water heaters and eco-cutes use a method in which hot water is drained from the upper side of the tank hot water by using the tap water depressurized from below and heated, and the hot water is extracted from above. Above, at 5 hours of the second midnight power, even if it is heated, the upper part is 65 ° C to 90 ° C, and the lower part is a state of a sloppy temperature even if the tank capacity is increased. Depending on the trend, it may be necessary to supply additional power at high cost during the daytime, so the tank capacity needs to be increased even if the tank remains under water. In order to increase the hot water discharge pressure, it is necessary to increase the strength of the tank.

  From such a thing, in the present invention, by adopting a general tap water decompression method and vacuuming simultaneously with the installation of glass wool in two gaps provided around the central tank of the heat storage tank type, By allowing the hot water of about 40 ° C, which is the temperature to enter the hot water tank, to supply tap water according to the level of the water level sensor as required by the user's selection, it will increase from 65 ° C to 90 ° C at midnight power. Tap water can be supplied to the central tank tank according to the level of the water level sensor as needed during heating, and it is possible to cope with the quantity of hot water. Because the internal pressure in the central tank exceeds a certain level, the pressure relief valve A and a one-way safety valve for pressure relief are installed in the middle of the drainage hose in the gate support base. Abnormal pressure in It is provided with the safety measures that can also be released to the bath as a Haiyu.

  Furthermore, in the event that abnormal pressure is generated even during heating other than in the central tank, in order to release this abnormal pressure, the walls of the central tank, the second tank, and the third tank provided at the lower end are supported. The three resin plates with the thickness to maintain the gap between each other support the wall with a thin heat insulating material sandwiched between them, and a relief valve for pressure relief leading to the internal hot water storage part is also provided in places other than this support .

As a core part of the present invention, according to Japanese Patent No. 3822543, Registration No. 312456, and Registration No. 312456, the ceramic membrane filter can remove not only dust and sebum but also bacteria and viruses from the pores of the surface of the ceramic membrane. If necessary, pigments, odors and other components can be removed in the post-process after filtration of the ceramic membrane filter case as needed, and the filtered solution stored from the inside of the ceramic membrane filter case can be removed from the air. By discharging at the same time with pressure, it is back-washed, and dust, sebum, bacteria and viruses attached to the surface of the ceramic membrane filter are also stored in the bag filter provided below. Discharge and clean with air only inside the ceramic membrane filter and the case. That the growth of bacteria can be prevented by placing and then dried, in the industrial filter from the can not be drying of the filter, it is also advantageous look.

In addition, a circulation system that filters the hot water in the bathtub even during bathing with a ceramic membrane filter, or a circulating system that filters the suspended matter, sebum, and dust in the bath and returns it to the bathtub is also useful. The filtered hot water is stored in a thermos-type vacuum tank consisting of a single or double vacuum tank with glass wool inside the gap around the central tank for storage. The vacuum bottle containing glass wool is covered with a second tank having a gap of 30 mm to 40 mm on the outside around the central tank, and a gap of 30 mm to 40 mm is provided between the outer periphery of the second tank and the third tank. The inner wall of the tank, which is provided in the lower part forming the central tank, and the L-shaped flange part is formed in the central tank, the second tank on the outer periphery thereof, and the third tank provided on the outer periphery thereof. Bottom In order to correspond to the L-shaped brim part of the upper tank part, the bowl-shaped lower tank part with an open top can also be installed with a gap of several tens of millimeters, Because three sheets are installed and fixed with a resin plate corresponding to the gap in between, and the lower tank part is also provided with an L-shaped brim part corresponding to the upper tank part, and it has a structure that can be joined with sandwiching each packing In addition, the vacuum can be removed as needed for repairs in the central tank, but it can be separated and the internal work can be performed. It is possible to re-vacuum with two copper pipes inserted into the gaps for performing the refining and re-caulking with the copper pipe.

  In addition, from the viewpoint of not escaping energy to the outside, it is also very important to use advanced night-time power mainly composed of the remaining hot water after filtration from the bathtub as heated energy and the second midnight power of electricity. For this purpose, considering the equipment that supports the air heat dissipation, heat transfer heat dissipation, convection heat dissipation, radiation heat dissipation, etc. from the hot water tank, the two construction methods of the vacuum structure and the heat insulating material were taken in, and at one place below the inlet Entry / exit passages, safety devices, measuring instruments, heating pipe heaters, air hoses for hot water, and tap water inlets and outlets for outside hot water production are provided below In addition, this pouring port is also used as a pouring base, so that it can be separated and lowered downward when not in operation, and when the pouring base is lowered, it is removed from the float valve with a rubber safety valve at the upper end of the pouring port. Heat dissipation Heat insulating material for closing the hole is provided so as to close the cylinder for.

  Therefore, as a heat storage tank type hot water storage tank, we believe that heat retention to prevent heat dissipation is important, and from this viewpoint, in the present invention, the outside of the stainless steel central tank with a mirror surface is regarded as the inner wall of the second tank. It is possible to use a single type with a gap of 30mm to 40mm and a glass wool sealed in this gap to make a vacuum, but in order to withstand long-term use of 20 or 30 years, the outer circumference of the second tank Assuming that the outer wall is covered with the outer wall of the third tank, the gap is 30mm to 40mm apart and glass wool is sealed and its vacuum is not necessary for long-term use. In order to prevent convection in a vacuum, the inner and outer peripheries of the second and third tanks are vacuumed together with the use of a semi-mirror surface SUS430 that can realize the surface. Reflect the radiant heat inside Therefore, even by the reflection plate provided on their clearance encapsulated glass wool surface (aluminum foil plates), it causes the function to confine the heat radiation.

  As described above, in the present invention, the glass tank with the reflector and the vacuum part are enclosed on the outside of the central tank made of stainless steel, and further providing two at the same time, further increasing the heat storage effect. Also, in the method of pouring hot water into the central tank, the upward movement by the vertically movable pouring gate support from the lower part is only during heating, and other than that, the downward movement from here Three sheets of resin plates that can prevent heat transfer and heat dissipation and support the central tank, the second tank, and the third tank to form a gap are between the first and second sheets, and between the second and third sheets. Between the sheets, a thin heat insulating material is sandwiched between the sheets so that the internal heat due to heat transfer from the central tank wall from the resin plate to the second tank wall and the third tank wall is devised.

  In addition, when hot water has entered the storage tank to a certain level, the rising hot water tank with the bottom at a position where the pipe heater attached to the pouring gate support does not come into contact with the upper mouth from below Sealed in an inverted cone shape, fixed to the upper tank plate, and fixed inside the central tank. When the rising hot water tank is installed inside, the pressure around the inverted cone is reduced. Through the valve, tap water is supplied to the tank as a thin tube that can supply tap water from below, so the hot water in the lower area is heated by the pipe heater only when the gate support is raised. Ascending flow is blocked by the lower end of the rising hot water tank, the tank body wall surface, and the spiral-shaped narrow tube by the upward flow, so that hot water is stirred in the hot water tank and the inside of the narrow tube It is also heated in the running water, rises by the pressure of the pressure reducing valve, enters from the upper end of the hot water tank, passes through the inside of the tank and is discharged from the lower end of the hot water tank. Concentrate the entrance and exit on the upper tank wall for a structure that can be taken out to the outside, reducing heat dissipation from the rising hot water tank and helping the heat retention of the hot water tank itself. It has a structure that prevents a drop in hot water temperature.

  For this reason, in the case of 2nd midnight power or Chubu Electric Power from the upper end wall of the rising hot water tank for 5 hours from 1 am to 6 am of the specified time, the night time from 11 pm to 7 am Before and after the contract time of 8 hours, while the stored clean water is filled, the heat will be exchanged for a long time due to the hot water temperature of the stored clean water. The tap water in the tank rises and accumulates above the hot water tank, and when hot water is taken out from the discharge pipe, it is usually raised at a water pressure of about 2 to 3 atm by the pressure reducing valve provided at the tap water inlet, and the tap water is placed inside the lower end of the hot water tank. Since water is introduced, tap water is supplied from the discharge pipe when hot water is used, and this structure is the same as the tap water supply structure in late-night electric water heaters and Ecocute, In the rising hot water tank structure of the present invention, there is a storage hot water around it, and this stored clean water is in a hot water storage tank with vacuum insulation structure containing two glass wools, and is heated to 65 ° C to 90 ° C with midnight power. There is a difference that has been done.

  This discharge pipe passes through the three resin plates sandwiching the three heat insulating sheets provided below through the housed purified water inside the central tank which is a heat storage tank type, and goes to the outside It is a structure that can be taken out, and at the end of the discharge pipe, it can be used by mixing with tap water by a thermosted shower mixing plug or other mixing plug.

  In response to the problem of CO2 reduction, which is a global proposition, the present invention is not limited to existing baths in Japan, including current gas equipment and petroleum equipment. An invention that can deal with this, there is a bath in which heat energy accounts for 30% of the energy use in CO2 countermeasures at home, but as this corresponding product, there is an eco-cute marketed by about 10 companies in Japan However, the main unit price is 600,000 yen to 950,000 yen (the actual price is also about 500,000 yen, the construction cost is about 120,000 yen: about 620,000 yen in total) The fuel cost of the bath costs 7.800 yen per month in terms of city gas, and the monthly night water heater also costs 4.800 yen. The difference from the eco-cute fuel cost is about 6,000 yen, so depreciation is required. In However, it is a disadvantage that it takes 9 to 10 years to calculate and is too expensive in pursuit of high functionality, which is a general Japanese trend that values user convenience.

  Therefore, once the hot water supply type is renovated with gas or oil, it will be necessary to renovate the conventional water heater or to make a hot water supply system for the house. There are drawbacks that must be waited for, and the problem that the invention is trying to solve is to make the function simple with the spirit of consideration for these users, and to devise measures to prevent the energy from escaping to the open air as much as possible, recycling both water and energy And the energy to heat is the result of devising the central tank, which is a heat storage tank type hot water tank, which is going to be finished in 5 hours of the second midnight power or 8 hours of nighttime power that is left in the middle of the night. The rise of hot water is also limited by the refraining of the use of electricity, but it can also be used in the daytime, and the equipment is different from Ecocute and late-night electric water heaters. Because also of the gas hot water supply system and oil type hot-water supply system to enable use as it features, reduction of construction costs also many things in one user of thinking, there is an advantage that can be the use of even going ways.

  In addition, the hot water production method, which can be generated by a heat exchange system using midnight power in hot water, can be solved by adding additional filtration with a finished ceramic membrane filter. Depending on the preference of the hot water, it is possible to use hot water only for the bathtub hot water, and while the hot water tank is in the stored clean water, the hot water tank itself exchanges heat at the temperature of the stored clean water. The tap water will also rise in temperature and accumulate above the tank, but even after being heated by the pipe heater A, there is a merit that it can be heated for a long time at the temperature of the stored purified water. It is possible to control with a typical controller, and in this case, it will be the same specification as Eco Cute and late-night electric water heater, but it may not be used like this There are many of selection skills such as the ability.

  In this way, the waste of equipment by saving CO2 by saving energy consumption in the bath, preventing expensive equipment, reducing construction costs, and maintaining the equipment of the hot water supply system in use Decrease.

According to the present invention, the hot water 2 pumped up from the bathtub 1 is stored outside the bathtub while being ultra-precisely filtered through the ceramic membrane filter of the ceramic membrane filter case 5, and the outer periphery of the central tank 16 with the flange is reflected. A second tank 15 with a flange is provided so as to have a vacuum part A30 having a vacuum gap A26 at the same time as the glass wool 32 with a plate, and a vacuum gap is formed at the outer periphery of the second tank 15 with a flange simultaneously with the glass wool 45 with a reflector. A third tank 13 with a flange is provided in a form covered with a vacuum part B31 having B27, and an upper tank of three tanks constituted by the central tank 16 with a flange, the second tank 15 with a flange , and the third tank 13 with a flange. Corresponding to the flanges provided at the lower ends of the parts, the lower tank 19 for the central tank with the flange, the lower tank 20 for the second tank with the flange, and the lower tank 21 for the third tank with the flange are connected with the packing therebetween. The upper tank part corresponding to the lower tank part can be integrated, and two resin plates are sandwiched between the lower tanks in the center hole provided at the center of the lower end of the lower tank part. In order to be able to form a vacuum gap at two locations, the copper plate A49 for air venting and air venting at two locations other than the resin plate center hole 28 so that the vacuum can be removed after the integral formation on the two resin plates. A copper pipe B50 is provided, and after evacuation, the pipe is crimped to form the above two vacuum gaps, and a cantilevered float valve with a rubber safety valve so as to close the upper hole of the resin plate central hole 28 22 is an eco-warm water heater with an open support type only in the lower part.
As the second aspect, in the heat retaining structure of the central tank 16 with the flange stored outside the bathtub 1 of the first aspect, the gate support can be moved up and down freely by the gate upper and lower cylinders 14 capable of moving up and down the gate support base 8 provided below. In the base 8, a purified water hot water hose 6, an air hose 10, a hot water hose 23, a water supply hose 37, and a pipe heater A35 are installed and fixed. When this rises, the upper end of the pipe heater A35 is made of rubber. The float valve 22 with a safety valve can be opened and closed. When the float valve 22 is lowered, the left and right heat insulation blocks 12 are closed by the left and right heat insulation block opening / closing cylinders 11. A hot water heater with an eco-warming hot water characterized in that hot water 2 can be quickly returned to the bathtub 1 from the hot water hose 23 by supplying high-pressure air from 10.
As the third aspect, in the heat retaining structure of the central tank 16 with a collar stored outside the bathtub 1 of the first and second aspects, the lower lower end provided in the hot water of the stored clean water 24 stored therein is narrow, A rising hot water tank 60 having a curved shape and an inverted conical shape at the time of installation is fixed around the outer periphery of the hot water tank 64 so that a tap water heating tube 64 is spirally wound. 33, it can be poured into the lower part through the upper hot water tank upper part 62 and heated by the pipe heater A35 provided below the hot water tank 60 in the stored clean water 24. The heated hot water gathers in the upper part of the rising hot water tank 60, and when the hot water becomes full in the tank, the hot water is discharged from the rising hot water tank discharge pipe 65. Or eco Agariyu with water heater according to any one of 2. As a fourth aspect, in the heat retaining structure of the central tank 16 with a collar stored outside the bathtub 1 of the first, second and third aspects of the bathtub 1, it is provided in the hot water of the stored clean water 24 stored therein. The rising water tank 60 processes only tap water by heating the pipe heater A35, and the stored purified water 24 does not return to the bathtub 1, but fills the bathtub 1 only with the heating water of the tap water in the rising water tank 60. The water heater with eco-raised hot water according to any one of claims 1 to 3. It is.
To solve these problems, as a means, we can add a low-cost device such as a gas water heater currently used or a hot water heater using petroleum, and provide functions equivalent to those of Ecocute and midnight electric water heaters. In order to reduce CO2 emissions by saving energy in the bath itself, the hot water in the bath is filtered with a ceramic membrane filter so that it has the same quality as tap water. In order to prevent the escape of energy to the outside air, two-stage evacuation to the outer periphery of the stainless steel central tank and the formation method are as follows. The heavy coating makes it difficult for convection and radiation to occur even if the vacuum breaks. In addition, the central tank and the outer stainless steel outer wall provided on its outer periphery are mirror-finished and sealed inside. Also have a function to reduce the heat radiation at two features to be reflected by the aluminum foil Suuru.

  In addition, even in the method of pouring purified water into the central tank, the central tank provided in the lowermost part and the three resin plates with the central hole capable of supporting the two outer tank walls are the central tank, the second tank, and the third tank. A thin heat insulating material is sandwiched between the three resin plates that are independently fixed in the respective lower wall holes forming the three resin plates, and the three resin plates are connected together with an adhesive together with screws. By fixing, the device can be simplified and the cost of the device can be prevented from increasing.

  The supply and discharge of purified water to the central tank is concentrated on the bottom support stand provided at the bottom, and when the heating pipe heater is down, replacement of parts etc. is easy outside the machine. This means that the construction and maintenance costs can be reduced, and only when the gate support is raised, the pipe heater is installed inside the inverted conical hot water tank from the lower part of the hot water storage tank. When the pipe heater is energized by heating the hot water, the hot water rises from the lower part and flows while heating the bottom and walls of the hot water tank, the narrow pipes installed around it, and the tap water flowing inside it. The hot water accumulated in the upper part of the rising hot water tank is discharged when the outlet pipe outlet is opened by the pressure of tap water supplied through the pressure reducing valve introduced into the bottom part above the outlet pipe at the upper end of the hot water.

  Also, hot water can be supplied from the bathtub currently in use via a pump to the ceramic membrane filter case, and hot water can be returned from the central tank to the bathtub through the spout support stand from the middle of the piping provided in the bathtub. In addition, since gas equipment and petroleum equipment that are in use can be used as they are, it is possible to reduce waste due to construction by maintaining the equipment itself.

  As a method of making the rising hot water, there is a method in which hot water of tap water stored in the central tank is circulated to the outside by a pump or the like, and heat exchange is performed, but about 43 ° C starting from the remaining hot water of the bath as in the present invention. The heat exchange with hot water is very inefficient, and the heat exchange at the outside is about 8:00 pm, which is mainly used as hot water for overheating from 1:00 am to 6:00 am heated at midnight power. The temperature drop due to heat radiation is considered to be severe for 12 hours, and from this point, the hot water tank is heated by the pipe heater in the central tank of the present invention which is a heat storage tank, and is present in the stored purified water as it is. It is very useful and highly effective, and it is very effective that the user can select how to use this structure with the controller.

  It is possible to fill the tub with only hot water made only from tap water, but due to the structure of the hot water tank, the use of hot water from the upper side of the tank can heat up in 5 hours or 8 hours. However, there is a possibility that the use of the nighttime power alone may lead to waste due to the capacity of the pipe heater and the use of daytime power.

  Moreover, the method of providing a two-stage gap outside the outer periphery of the central tank of the present invention and providing glass wool with a reflector in it can be used not only for heat storage tanks but also for heat insulation of tube structures. Also, it can be used as a part of the discharge pipe that is exposed to the atmosphere from the rising hot water, so that it has the advantage of having the function of keeping the hot water in the discharge pipe warm and difficult to cool.

FIG. 3 is a cross-sectional side view from the bathtub 1 of the first embodiment to the rising hot water tank 60. The structure cross-section side view of the resin board of the lower tank support part of Example 1. FIG. FIG. 3 is a cross-sectional top view of a central pipe of the gate support of the first embodiment.

  The present invention uses extra water at midnight by using the 2nd midnight power used to purify the hot water of the bath and maintain the heated energy, devise a heat insulation structure, and reheat to measure CO2 reduction. By using it, we will provide a structure that can recycle electricity, and a device that adds a function that can process hot water that is often requested by the user during heating.

A first embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, hot water 2 is pumped through a pipe that connects between the bathtub 1 and the outer gas kettle 25 via the electric pump 3, and ultrafine filtration is performed in the ceramic membrane filter case 5 via the bathtub pumping hose 4. The hot water discharged from the water purifying hose 6 is fixed by inserting a pipe end into the gate support base 8, and the hot water hose 23, the air hose 10, and the water hose 37 are stored and fixed simultaneously.

  The ceramic membrane filter case 5 has a structure in which a ceramic thin film is baked on a ceramic base material as shown in Japanese Patent No. 3822543, Registration No. 312456, and Registration No. 312473. As required by the above-mentioned patents and utility models, the inside of the filter case can be used repeatedly for ultra-precise filtration with ceramic membrane filters as needed, including dust, bacteria, sebum, and viruses. Since the filtrate stored in the filter is backwashed with air from the inside, dust, bacteria, sebum, viruses, etc. adhering to the filter surface are stored in a non-woven back filter provided under the filter. It can be used repeatedly.

  In particular, in the case of hot water at about 40 ° C., which has become a problem in a 24-hour bath, due to the problem that Escherichia coli, generaus bacteria, etc. propagate in industrial filters and pipes, the filtration is completed inside the ceramic membrane filter case 5 In order to keep water and hot water strictly, the lower valve of the back filter provided below the ceramic membrane filter case 5 is opened and air is blown out even when the filtrate is exhausted, thereby drying the inside of the pipe and the filter. To be electrically controlled.

  In the present invention, the problem of how the hot water 2 sent into the central tank 16 with the brim is filtered and the hot water 2 fed into the central tank 16 with the brim as the stored purified hot water 24, It is important that heat can be prevented and heat can be kept for 24 hours or more, and the water level sensor 40 and the temperature sensor 43 provided in the central tank 16 with the brim can electrically respond to the water level and temperature.

For this reason, the vacuum part A30 which is a gap formed between the central tank 16 with the brim and the second tank 15 with the brim provided on the outer periphery thereof, and the glass wool 32 with the reflector as the heat insulating material enclosed therein and the A vacuum part B31 in a gap formed between the outer periphery of the second tank 15 with the flange and the third tank 13 with the flange is sealed with the glass wool 45 with the reflector and kept in a vacuum. If new insulation is effective instead, it can be used. Convection phenomenon and reflection of the stainless steel wall should a vacuum leak occur between the stainless steel walls forming each wall. The reflection phenomenon by the glass wool reflector and the thermal radiation phenomenon is prevented. This is because the flange part is provided at the lower end part provided in each upper tank part formed by three tanks provided above. Central tank 16 with brim by providing A second tank 15 with a flange on the outer side, and a third tank 13 with a flange on the outer side, and three curved lower tank parts with a flange provided on the lower side corresponding to the flange part sandwich the packing. Thus, the upper tank part and the lower tank part can be integrally connected with screws.

As shown in FIG. 2, the curved lower tank portion with the flange is a lower tank 19 with a flange for the central tank.
A first tank supporting resin plate 67, a second tank supporting resin plate 68, and a second tank supporting lower tank 20 and a third tank flanged lower tank 21 provided in the three central holes. Between the bottom end supporting resin plate 69 and the screw provided on the top end supporting stainless steel plate 66 provided at the top end with the thin heat insulating material A70 and the heat insulating material B71 interposed therebetween, respectively, the coupling fastening screw 42 is used. The center hole is penetrated, and when the gate support 8 is lowered by two slide guide rods 18 by the cylinder 14 downward, the left and right heat insulating blocks 12 that form a pair on the left and right are left and right. When opened by the heat insulating block opening / closing cylinder 11, when rising through the outer diameter O-ring 36 to the outer diameter of the gate support base 8 so as not to cause water leakage between the gate support base 8 and the central hole. Fit smoothly and cause water leakage Which is to be no structure.

  The upper end support stainless steel plate 66 is provided with a rubber safety valve float valve 22 with a hollow in the lower center so that it can be slid open and closed in a cantilevered manner. 2 and is lifted in contact with the pipe heater A35. Except for the space of the float valve 22 with a rubber safety valve, the hot water discharge hose 65, Since the pressure relief safety valve B41 is fixed so that it can be taken out and taken out to the outside, the pressure relief safety valve B41 and the rubber safety valve are used when a pressure exceeding a certain level is generated even when the gate support 8 is lowered. It also has a structure that can be discharged from the attached float valve 22 to the lower side outside the tank.

  As shown in FIG. 3, the gate support 8 is provided with a pipe heater A <b> 35 that generates heat by electric power in the stored purified water 24 only when the cylinder 14 is lifted, The hose 6 for drainage, the hose 23 for drainage, the hose 37 for water supply, and the hose 10 for air are fixed, and the temperature sensor 43 and the safety valve A44 for pressure relief are also installed and fixed. At the time of pressure increase due to excessive temperature, if excessive pressure is exceeded, it can be released downward by the pressure relief safety valve A44, and the drainage hose 23 as shown in FIG. If excessive pressure is applied to the inside of the stored purified water 24 that exceeds a certain pressure by the one-way drain valve 39 provided in the middle of the stored water, the stored purified water 24 is discharged from the drain hose 23 to the bathtub 1. It made.

  In the case of Chubu Electric Power, the second midnight power that is the main focus of the present invention is to store hot water of about 40 ° C. by heating the pipe heater A35 from below for 5 hours from 1 am to 6 am By generating heat in the hot water 24, the hot water in the central tank 16 with a flange is heated while forming an upward flow to a high temperature of 65 ° C to 90 ° C. It is a manufacturing method.

  The rising hot water tank 60 has a rounded shape with a narrow tip, like a rising hot water tank lower part 61, and an upper part that is wider and curved upward than a lower like a rising hot water tank upper part 62. When tap water is introduced, the pressure of the tap water of about 2 to 3 atm is heated by the tap water pressure valve 33 when the water is full and heated by the pipe heater A35 from the lower part 61 of the hot water tank. The hot water rises smoothly and rises smoothly so that the hot water tank 60 can be heated, and the tap water heating thin tube 64 is fixed in a spiral form around it. When heated by the pipe heater A15, when the heated rising hot water rises, the effect of stirring the surrounding stored clean water 24 is obtained.

  The tap water heating thin tube 64 is connected to the lower end support resin plate 69 and the second tank support resin plate 68 from the water supply hose B34 via the water supply electromagnetic valve B48 and the tap water pressure regulating valve 33, and the upper end. When connected to the tap water heating thin tube 64 from the supporting stainless steel plate 66 and heated by the pipe heater A35, it is gradually heated by being replenished with tap water, fixed to the upper part 62 of the rising hot water tank, By installing the tip of the tap water heating thin tube 64 at the bottom, it can be gradually accumulated in the upper part of the rising hot water tank 60 by being discharged as hot hot water.

Since the upper tank part and the lower tank part are integrated as shown in FIG. 1, the air vent penetrating downward from the central tank lower tank supporting resin plate 67 as shown in FIG. A copper pipe A49 is provided, and the second tank lower tank support resin plate 68 is provided with an air vent copper pipe B50 penetrating downward, from which an upper tank section that forms a gap therebetween, and remove the air of the vacuum unit A30 and the vacuum unit B31 is a vacuum moiety attached to the lower tank portion, so as to be vacuum , And has a structure that can seal the copper pipe Te busting When the vacuum is complete.

  In this way, the stored purified water 24 having a temperature of about 40 ° C. in the central tank formed by two vacuum tanks is heated by the second midnight power from below the stored purified water 24, so that 65 The heated hot water tank 60 is gradually heated while being heated to ℃ to 90 ° C., and the tap water inside the hot water tank 60 moves upward and is stored. Even if the valve B48 is used up, it can be filled and when tap water is filled inside, if hot water is used with the water tap or thermostat shower mixer tap attached to the rising hot water tank discharge pipe 65 by the tap water pressure The structure is such that hot water that rises due to the pressure of tap water and accumulates above the hot water tank 60 is discharged by the pressure of tap water fed from below.

  Further, the stainless steel material of the outer wall of the vacuum part B31 formed by a double vacuum chamber is not affected by the internal temperature, and therefore is 90 ° C. or less. Covering with thick Styrofoam 29 is 90 ° C or less, so there is no melting phenomenon, and this makes it possible to avoid the influence of the heat insulation effect and the change of outside air, including the outer cover. It has become.

  As an example of utilization and use of the present invention, it is of course used for a domestic bath, but even for industrial use, in a heat storage tank, the temperature change occurs with a time difference, so this two-stage reflector glass The heat insulation method using a vacuum chamber using a vacuum gap filled with wool is simple in structure and can be installed at low cost, and it can be applied to hot spring facilities, midnight electric water heaters and eco-cutes in various places by the heat insulation method shown in the present invention. It is possible, especially for EcoCute, because it is difficult to cool the stored purified water 24 even without using a filter with a ceramic membrane filter case. With heating, the heat insulation structure is useful for 12 hours thereafter, and it can be used for heat storage tanks and cold storage tanks including refrigeration and freezing.
