Description

  The present invention provides a single or double vacuum section on the outer periphery of the hot water tank, and increases the function as a heat storage tank by simultaneously enclosing a heat insulating material over the vacuum section, and from the heat storage section of this function to the outside In order to prevent heat dissipation to the heat, the vacuum part formed at one or two gaps is reflected by insulation such as glass wool, polyester insulation, urethane foam or silica-containing vacuum insulation, and aluminum foil. Simultaneously inserting and evacuating the composite material prevents the release, radiation, and radiation of energy into the atmosphere. When supplying and removing purified water or tap water, leave it outside when it is not necessary. In this way, a device that uses the second midnight power to measure heat transfer and to prevent long-term use by preventing radiation and secondary radiation from the entire device, and to reduce costs, reduce CO2, and reduce carbon. Is intended to provide.

  Conventionally, in order to have a function as a hot water heater, tap water is generally introduced from the bottom of the tank and heated, and hot water accumulates upward. In most cases, the method of taking out the outside is provided, and Japanese Patent No. 3729897 and Japanese Patent Application Laid-Open No. 2001-116367 are also this method.

  For this reason, in the case of taking a bath for a long time, the upper layer part becomes hot water, but there is a phenomenon that cold water remains below the lower layer part. The fact that the temperature difference is large has been experienced, and in this case, it will be stirred with a stirring rod by human power.

  This means that whatever the heating mechanism is, hot water at the top and cold water at the bottom, during hot water storage inside the tank, not only does the heat move constantly and the heat efficiency decreases, but the heat is also transferred to the tank wall. There is also a problem that heat transfer is likely to occur and the effect of the heat insulating material is likely to be reduced.

  On the other hand, if the hot water is used at 65 ° C to 90 ° C, where bacteria and viruses are killed, the hot water temperature is about 45 ° C, which is necessary for the mixing tap 58 with a motor strong and weak thermostat that can be mixed with tap water in the middle of hot water. There is a great merit that the capacity of the tank can be reduced.

  For this reason, storing the full tank capacity while heating the tank with the hot water in the bathtub at the required temperature is considered from the efficiency of use of the double vacuum and double heat insulation tank as in the present invention. Even if it is good and industrially, the function as a heat storage tank and a liquid production machine that can be stored as a uniform liquid in a specified amount at a liquid temperature of the required required temperature is very useful.

  For this reason, the present invention is a very useful technology not only for the bath but also for the industry as a whole. However, the number of baths for consumer use is particularly large and will be discarded when nuclear power generation proceeds in the future. In terms of the use of the second midnight power, the global significance of diversifying the use of CO2 reduction and low-carbon technologies is also significant.

  Therefore, even when the tank is full during heating, the phenomenon that the upper part is hot and the lower part remains cold is inconvenient. Generally, the upper hot water is reduced outside the tap water. It is thought that it is uncertain what the temperature will be because of the function of sending out at about 2 to 3 atmospheres, and a double double vacuum mechanism tank with a heat storage type heat insulation material with a full thermal insulation function like the present invention product Then, it seems that it is better to keep the temperature of the hot water in the tank as uniform as possible in terms of heat insulation.

  For this reason, in the present invention in which only the upper part of the tank can be opened, by controlling the raising and lowering of the pouring gate support base 8 by the controller, the hot water drain hose 23 is heated while being heated by the pipe heater 35 inside the tank or outside. Even while hot water is being taken out, it can be made uniform by moving the hot water up and down at a set temperature freely inside the tank.

  In addition, the tap water can be taken out by filling the tank with the tap water, but the spout is supported by the air pressure of the air hose 10 incorporated in the spout support base 8 by the controller instead of the tap water. Hot water can be taken out if the hot water hose 23 provided at the tip of the spout support base 8 is below the water surface when the base 8 is lowered.

  In addition, when the gate support 8 is moved up and down, if the controller controls the height and depth of the pipe heater 35 from the molten metal surface using the lower limit sensor 48, the middle limit sensor 47 and the upper limit sensor 46, the tap water is supplied. The timing of air supply from the air hose 10 can also be understood as needed.

Thus, if the height of the hot water hose 23 provided at the tip of the gate support stand 8 reaches the lower part of the tank, the tank can be filled with tap water supplied from the water hose 37. For example, the hot water taken out from the hot water hose 23 is discharged from the tap water of the tap water controlled by the electromagnetic valve 11 for water with a mixing valve 58 with a thermo-mechanically operated thermostat provided in the middle of the hot water via the drain one-way pressure valve 39. The hot water of the hot water of the stirring effect by the vertical movement is put in the bathtub 1 as the hot water 2 by the silicon cap-shaped brim plate 34 provided with a hole for facilitating passage of the hot water support 8 and the hot water provided at the tip thereof by the function of the controller. This is a dynamic phenomenon and can be used with a uniform set temperature of hot water.

Japanese Patent No. 4571703 Japanese Patent No. 3822543 Utility Model No. 312473 Publication Utility Model No. 312456 Publication Patent No. 3729897 JP 2001-116367 A

In the present invention, there is a midnight electric water heater and Ecocute (registered trademark) as a heating method with electric power for hot water supply in Japan, in response to the problem of CO2 reduction, which is a global proposition, but nuclear power is targeted for 2030 from now on. It is said that power generation will be 50% in Chubu Electric Power, but waste is eliminated by power load leveling by focusing on 5 hours of the 2nd midnight power from 1 am to 6 am when the usage is drastically reduced Is
The purpose is to develop a compact and efficient product by using a heat storage tank with a vacuum heat insulating material in a mechanism that is difficult in the conventional system using water pressure from below the tap water.

  Particularly, in the case of the subject of the present invention, there is a problem in the method of storing hot water inside and the method of taking out hot water in midnight electric water heaters and eco-cutes, which tend to be large in size, and the figure is large in any case.

  For this purpose, in the present invention, in addition to the single or double vacuum structure of the structure of Japanese Patent No. 4571703, an optimum heat insulating material is simultaneously sealed in the vacuum gap to achieve a further heat insulation effect. Thus, the upper part, which is also a drawback of the above-mentioned conventional product, has the disadvantage that the upper part is hot water and the lower part is cold water, which is a problem-solving invention that eliminates inefficient storage hot water.

In particular, with regard to the temperature of hot water during hot water storage, even in general thermos bottles, contact heat transfer occurs between the stainless steel interior or the stainless steel exterior derived from the stainless steel interior and the upper plastic lid, and the heat storage decreases due to heat dissipation to the outside air. It is a problem to prevent this violently, and only the float valve 22 provided between the central tank 16 with the flange with respect to the upper part of the pouring gate support 8 provided at the upper part of the present invention is opened. There is also a problem of contact with the atmosphere only through the department.

  This is because heat transfer and heat dissipation due to direct feeding of tap water in a conventional late-night electric water heater or Eco-cute from below or direct removal of hot water from above cannot be prevented. The structure is a problem that seems to be uneconomical even in a method that can produce hot water at low cost such as Ecocute.

  Moreover, the hot water in the upper part and the cold water in the lower part are problems that are not only inconvenient but also insulative in heat retention due to non-uniform hot water temperature in the heat circulation environment.

Summarizing the issues as described above, the first is that Chubu Electric Power can hold up to the required time as hot water energy only by heating with the second midnight power for 5 hours from 1 am to 6 am .
Secondly, the tank capacity is efficient in terms of energy distribution, and it is easy to install, including installation, even in a small installation area.

Third, the heat insulation structure is improved to prevent heat dissipation, heat transfer and radiation into the air.
Consider from the viewpoint of preventing diffusion heat dissipation.
Fourthly, prevention of water leakage from the storage tank itself.
Fifth, improvement of tap water input method and hot water extraction method.
Sixth, equalizing the hot water temperature in the tank.
Seventh, diversification of how hot water is taken out to the user's preference.
Eighth, it is inconvenient that the size of the central tank 16 with a brim is determined, and the bathtub 1 and the amount of hot water to be used cannot be determined.
Ninth, it is also a necessary issue that the hot water used in the bathtub can be safely reused.
Tenth, if the tank is stored with hot water, if hot water is supplied to the faucet at the end of the bathroom with a thermostatic mixer tap, the house needs to be renovated, and the construction cost is high. This hinders the spread of installed baths.

The invention, as claimed in claim 1, with filtered water 2 pumped from the bath 1 with a ceramic membrane filter casing 5, the method of storing outside bath, reflecting composite outer peripheral outer flange with the central tank 16 and the heat insulating material 32 At the same time, it has a vacuum part A30 having a vacuum gap A26, and a second tank 15 with a flange is provided so as to be covered. A vacuum gap B27 is formed on the outer periphery of the second tank 15 with a flange simultaneously with the reflective composite material and the heat insulating material 45. The upper tank plate is sandwiched between the flanges provided at the upper ends of the upper ends of the three tanks so that the vacuum part B31 that is held can be sandwiched, and each can be coupled with screws, and the third tank 13 with the flanges is provided, Corresponding to the flanges provided at the upper ends of the upper tanks of the three tanks composed of the central tank 16 with flanges, the second tank 15 with flanges, and the third tank 13 with flanges, respectively, 2nd tank with tank plate 19 and brim Upper tank plate 20 and a third tank for the upper tank plate 21 with the collar are adapted to be coupled across the gasket, made of resin for each tank corresponding to the flange portion provided at the upper end portion of the third reactor 2 so that the upper tank plate can be coupled with packing , and two resin plates are sandwiched between the upper tank plates of the center hole provided in the center of the upper tank plate so that two vacuum gaps can be formed. An air vent copper pipe A49 and an air vent copper pipe B50 are provided at two locations other than the upper central opening 28 so that the vacuum can be removed after the resin plate is integrally formed. All the tap water inlets and hot water outlets are provided with a cantilevered float valve 22 so as to form the two vacuum gaps and close the upper hole of the upper central opening 28. It is characterized upward openable reservoir for providing the upward Regenerative water heater.

As the second aspect, in the regenerative water heater according to the first aspect, the upper tank plate for the third tank with the flange is used to move up and down the gate support base 8 provided at the upper part of the central tank 16 with the flange of the water heater. An upper chimney-shaped slide support base 18 is fixed with a heat insulating material 21 interposed therebetween, and a guard motor 14 is connected to a rotating screw rod 54 at the top so that the gate support base 8 can freely move up and down. 55 can be moved up and down by forward / reverse rotation, and the multi-core spiral tube 56 housed below the hoses and electric wires, which are necessary component parts, are built in to follow the movement of the gate support base 8 and extend. A regenerative hot water heater that can be taken out by being able to stay .

As a third aspect, in the heat retaining structure of the central tank 16 with a collar stored outside the bathtub 1 in the heat storage type hot water heater according to the first or second aspect , the amount of stored purified hot water 24 stored in the central tank 16 with a collar is determined. Water level sensor 40 with a hot water temperature sensor 40 replenishes tap water with a heating part by a pipe heater 35 provided at a position distant from the front end of the spout support base 8 and a tap water pipe at the front end of the water tap provided by the pipe heater 35. The height of the hot water surface of the hot water 24 can be adjusted by a controller as needed, and the hot water temperature can be made uniform by the stirring effect by moving up and down with the silicon cap-shaped flange plate 34 provided at the tip of the pouring gate support base 8. the sprue temperature sensor 43 and up and down while observing the water detection sensor 5 provided at the tip of the support base 8, as needed for discharging hot tip mouth of the discharge water hose 23 is confirmed that there in hot water Regenerative water heater, which comprises discharging hot press water surface by air supplied from the air hose 10.

As a fourth aspect of the present invention, in the regenerative water heater according to any one of the first to third aspects , in the method of using the tap water pressure from the water hose 37 to supply the hot water 2 to the bathtub 1, A regenerative water heater , characterized in that tap water can be supplied from the lower lower end of the purified water 24 in the attached central tub 16 through the tap end pipe 44 to drain the hot water when the central tub 16 with a brim is full .

As claim 5, the supply of hot water 2 to the bathtub 1 by the regenerative water heater according to the foregoing claim 3, in first thing that restricts 80% of the volume of the collar with the central tank 16 within 90% pre The water temperature in the central tank 16 with the flange is made uniform by adding tap water to the required hot water temperature, or the hot water temperature is 90 ° C. to 65 ° C. without adding additional tap water. After setting the desired hot water temperature to the required temperature by stirring the hot water temperature at the top and bottom of the spout support stand 8, the water pressure is used for replenishing tap water from the lower side of the central tank 16 with the flange or by the air pressure. It is possible to supply hot water 2 to the tub 1 by adjusting the required hot water temperature by adding hot water from the hot water discharge hose 23 by hot water surface compression with a mixing tap 58 with a motor strong and weak operating thermostat. A regenerative water heater that can be set with a controller .

  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, like the normal thermos system, the opening part has all the tap water input part and hot water outlet part as an upward open storage tank provided above, so that the tank itself can be removed. Water leakage can be prevented by making the outer periphery a double vacuum chamber, and heat transfer and heat dissipation can also be prevented.

  In addition, when using hot water, the hot water support sensor 8 can be moved up and down as needed so that the hot water temperature is as constant as possible with respect to the temperature displayed on the controller. 57, temperature sensor 43, and water level sensor 40 with hot water temperature detection. The pipe heater 35 is used for heating based on the controller, and only the upper and lower sides are used to make the hot water uniform without heating. If the hot water temperature is too high, the hot water temperature can be lowered by adding tap water.

  In contrast to the conventional round shape, the narrow and narrow type required along the wall like the product of the present invention can also take a volume more freely than the round shape, and in the rectangular and open tank shape, it will be installed in the future. It is thought that it is a useful design even inside a bathroom, dressing room, laundry, kitchen, etc.

  In the product of the present invention of the upper open type, a second tank with a flange provided on the outer periphery is fixed in such a manner that a lid is attached to the flange of the central tank 16 with a flange with a top tank plate 19 for a central tank with a flange sandwiched between packings. 15. Further, the third tank 13 with a flange provided on the outer periphery also fixes the upper tank plate 20 for the second tank with the flange and the upper tank plate 21 for the third tank with the flange with the packing sandwiched between the flanges.

  Only the vacuum part B31 and the vacuum gap A26 that simultaneously encloses the heat insulating material 32 with the reflector between the second tank 15 with the flange provided on the outer periphery of the central tank 16 with the flange has a considerable heat retaining effect. A further heat insulating effect can be expected by simultaneously enclosing and vacuuming the heat insulating material 45 with a reflecting plate in the vacuum gap 27 formed by the third tank 13 with a flange, which is another tank, on the outer periphery of the two tanks 15.

Further, in order to prevent heat dissipation from the upper opening, the upper chimney-like slide support base 18 is fixed to the upper tank plate 21 for the third tank with a flange with a heat insulating material sandwiched between them, The outer diameter O-ring 36 provided on the outer diameter prevents the atmosphere from coming into contact with the atmosphere in a state of being blocked from the lower surface by the float valve 22 while the gate support 8 is inside. Can prevent heat dissipation.

  Further, a silicon cap-shaped brim plate 34 provided with a hole through which a central portion provided between the pipe heater 35 and the lower portion of the gate support table 8 is provided is fixed below the gate support table 8. Therefore, when the gate support 8 is lowered in the hot water, even when refilling tap water, it can be smoothly supplied into the hot water, and even when the gate support 8 is moving up and down, It has a feature that it can move smoothly and has the effect of stirring with a stirring rod.

  In order to solve these problems, the present invention provides a hot water heater and a water bath for a currently used bath as disclosed in Japanese Patent No. 4571703 for a hot water heater using a gas water heater or an oil water heater as a means. A pump is connected to the coupling pipe and rubber coupling pipe to reduce the cost of remodeling work.

  In the present invention, the hot water from the drainage hose 23 guided through the gate support base 8 is also supplied with tap water when the gate support base 8 is at the required height in the hot water by the water temperature detection level sensor 40. When the tap water is replenished from the pressure hose 37 through the pressure reducing valve 33 with check valve and the electromagnetic valve 38 for water supply, the hot water 2 can be taken out from the hot water discharge hose 23 with the reduced pressure of the water pressure. Even if air is supplied from 10, the same effect is obtained, and whether to use tap water or to use air pressure is determined by the user's selection by the controller.

  However, in the method using the water pressure of the tap water, if the tap water is introduced at the lowermost part of the hot water, the hot water from the hot water draining hose 23 is filled in the central tank 16 with a brim until the hot water is filled. 2 can not be taken out, and depending on which height position of the tank the pouring gate support 8 is moved, cold water will be drawn in the lower part. It is necessary to control the height of 8 with the controller.

  On the other hand, the method of supplying air with the air hose 10 has a drawback of requiring air, but the hot water discharge hose 23 is in an appropriate position in the hot water due to the height of the gate support base 8. Then, the hot water can be pumped up while the mouth of the hot water draining hose 23 provided on the pouring gate support base 8 is in the hot water by positioning with the controller.

  As described above, in the present invention, as an element mechanism for solving the problems of the present invention, firstly, a single or double vacuum chamber is provided outside the outer periphery of the central tank 16 with a flange, and a heat insulating material is simultaneously enclosed in a vacuum gap. Because of this structure, it is formed with a heat storage structure with a long-term heat retention structure.

  Second, the overall structure formed by the central tank 16 with the flange and the single or double outer layer provided on the outer periphery of the central tank is simultaneously formed upward. Therefore, if the gate support 8 is moved up and down in the hot water, the hot water will be evenly distributed. This is effective for preventing heat radiation to the atmosphere described in the sixth problem, and the energy in terms of tank capacity. The distribution is efficient, the installation area is reduced, and the apparatus can be made smaller.

Thirdly, in order to prevent heat dissipation and heat transfer into the air and to prevent radiation / diffusion phenomenon, in the heat transfer prevention, the entrance / exit is gathered in one upper place, and the radiation / diffusion phenomenon is eliminated. As described in the above, a vacuum gap A26 is formed on the vacuum part A30 and the vacuum part B31 formed by the second tank 15 with the flange to the central tank 16 with the flange and the third tank 13 with the flange on the outer periphery. And by vacuum- sealing the reflective composite material and the heat insulating material 32 and the reflective composite material and the heat insulating material 45 simultaneously in each gap of the vacuum gap B27, even if a vacuum leak should occur, between each tank wall Can prevent reflection, diffusion, radiation, heat transfer and heat dissipation.

Fourthly, prevention of water leakage from the tank, which is a function as a storage tank, can be further prevented because of the stainless steel tank having an upward open structure and a three tank structure.
Fifth, prevention of heat transfer and heat dissipation can be prevented by completely isolating the gate support base 8 from the tank by using an open type at only one upper position.

  Sixth, due to non-uniform flow of heat inside the tank due to non-uniformity of the heat of the tank wall due to non-uniformity of the heat of the tank wall due to non-uniformity of the heat of the tank wall due to non-uniformity of hot water in the tank, Since heat loss occurs, the hot water temperature can be made uniform as intended by the vertical movement into the hot water by the gate support stand 8 and the stirring effect in the hot water by the attached silicon cap-shaped brim plate 34 and the pipe heater 35.

Seventh, the diversification of hot water removal methods allows a number of user options with the controller.
As one of them, there is a spout base 8 in the hot water by the air hose 10, and if the temperature sensor 43 is appropriate, the hot water surface is pushed up from the air hose 10 by the controller. The pumping action can be performed.
As part 2, the tap water that has passed through the pressure reducing valve 33 with a check valve is discharged from the tap tip pipe 44 at a low temperature by the temperature sensor 43 of the tap support base 8 from the tap hose 37. When the tank becomes full by supplying, the hot water can be discharged from the hot water hose 23.

  Eighth, only the required amount of hot water 2 to be put into the bathtub 1 and the amount of hot water to be used for other purposes need only be stored by heating, such as midnight electric water heaters and eco-cute water. Since there is no need to heat the part inadequately, this eliminates the waste of heating energy and is a means of reducing CO2, so the user can specify the amount of water determined by the water level height sensor 40 with hot water temperature detection. Thus, the controller can determine the hot water temperature in the tank to the desired hot water temperature by heating the pipe heater 35, the height of the pouring base 8 and the uniform hot water temperature.

  Ninthly, as a method of using the hot water 2 after bathing, which has been discarded, as the remaining energy, the filtration of the dust, debris and bacteria by the ceramic membrane filter case 5 performed in Japanese Patent No. 4571703 is performed. It is also possible to supply the purified water with the filtered hot water hose 6, but the user can select it with the controller. In this case, the tap water supplied from the tap water hose 37 is from the tank capacity. It must be within 80%, and it is necessary to be able to adjust the hot water temperature by adding water when the hot water is made uniform by the pipe heater 35. This is the same with the method of heating by the pipe heater 35 using only tap water. However, in the tenth issue, eco-cute and late-night electric water heaters require home renovation and are now popular because they wait for new construction or renovation Slow.

  As described above, it is difficult to produce and supply only the necessary hot water, which is a drawback of midnight electric water heaters and eco-cutes, conventionally, the means for the problem is a structure by tap water supply from below and hot water extraction from above The hot water cannot be taken out unless the tank is full. This is a major factor that makes the use of intermediate hot water at the boundary between the upper hot water and the lower cold water incomplete and worsens the heat efficiency. is there.

  13 hours from 7 am to 7 pm by heating the second outer power from 1 am to 6 am for 5 hours by enclosing a heat insulating material on the outer periphery of the central tank 16 with a flange and simultaneously creating a vacuum. There is an advantage effect that it is possible to have 43 ° C. to be put into the bathtub 1 until later.

  While there is hot water in the central tank 16 with a brim, it is possible to secure the hot water temperature and quantity at the time of bathing by equalizing the hot water to the required temperature as desired. In addition, it is possible to select whether all of the hot water is from tap water or use both, so that waste of energy due to extra heating is eliminated and only the necessary hot water is heated to suppress the generation of CO2.

  In the present invention, only the amount of hot water required at home is heated, and the boundary water between hot water and cold water as in the prior art is not heated, thereby eliminating unnecessary energy consumption and at the pipe heater 35. If the hot water temperature in the tank is determined and specified to the controller, uniform hot water can be supplied.

Sectional side view from the bathtub 1 of Example 1 to the central tank 16 with a brim. FIG. 3 is a detailed cross-sectional side view of the upper opening of the first embodiment. FIG. 3 is a cross-sectional top view of a concentrated pipe of the gate support stand 8 according to the first embodiment.

  In the present invention, in order to reduce CO2, in order to save energy consumption, together with the method of reusing the remaining hot water in the bath, the energy source used should be only 5 hours of the second midnight power at night. For this purpose, the heat storage and heat insulation structure will be thoroughly improved, the manufactured hot water will be made uniform in the tank, only the hot water used will be heated, and the temperature of the hot water will be 90 ℃ to 90 ℃. In particular, the temperature can be raised close to 90 ° C, and mixed with tap water in the middle of the hot water hose 23 with a motor strong and weak operation thermostat, so that it can be supplied to the bathtub 1 directly at the appropriate temperature of the bath. Especially when the temperature is higher than 80 ℃, hot water 2 is doubled with tap water and can be supplied to the bath using the tap water in the tank using the equalization function. There are two examples.

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 connecting between the bathtub 1 and the outer gas kettle 25 via the electric pump 3 and is filtered through the bathtub hose 4 with the ceramic membrane filter case 5 while performing ultra-precise filtration. Hot water discharged from the filtered hot water hose 6 is inserted and fixed to the gate support 8 via a multi-core spiral tube 56, and the hot water hose 23, the air hose 10, and the water hose 37 are the same. Is installed.

  The ceramic membrane filter case 5 has a structure in which a ceramic thin film is baked on a ceramic substrate as shown in Japanese Patent No. 3822543, Registration No. 312456, and Registration No. 312473. As shown in 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 through dust, bacteria, sebum, and viruses. Backwash the post-filtration liquid with air from the inside and backwash the ceramic film on the surface, so that dust, bacteria, sebum, viruses, etc. attached to the filter surface can be made of non-woven fabric provided under the filter. Because it is a structure that can be stored in the back 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 to be able to keep the heat for more than 24 hours by preventing heat dissipation. The water level height sensor 40 and the temperature sensor 43 with hot water temperature detection provided in the central tank 16 with the flanges can be used by electrically checking the water level and temperature. Can do.

For this reason, the vacuum part A30 which is a gap formed between the central tank 16 with flanges and the second tank 15 with flanges provided on the outer periphery thereof, and the reflective composite material and the heat insulating material 32 which are heat insulating materials enclosed therein The vacuum part B31 in the gap formed between the outer periphery of the second tank 15 with the flange and the third tank 13 with the flange encloses the reflective composite material and the heat insulating material 45 and is kept in vacuum. If a new heat insulating material such as a silica-containing vacuum heat insulating material (VIP) is effective instead of the material, it can be used, and it should be vacuumed between the stainless steel walls forming each wall. The convection phenomenon when leakage occurs, the reflection of the stainless steel wall, and the reflection phenomenon of the glass wool reflector prevent the thermal radiation phenomenon. This is provided in each tank that forms the three tanks provided below. By providing a flange on the upper end A central tank 16 with a flange, a second tank 15 with a flange on its outer side, and a third tank 13 with a flange provided on the outer side thereof, are three sets of upper tank plates with a flange that are provided on the upper side that can correspond to this flange portion. Each has a structure that can be connected with screws with packing in between.

  As shown in FIG. 2, the brim portion of the central tank 16 with the brim is fixed to the upper tank plate 19 with a brim central tank made of resin via a stainless steel plate 53 provided on the base, and the second brim with the brim.
