Description

  The present invention creates a hot water storage tank space that partitions the total heat exchange type ventilation fan and a part of the basement space and installs a hot water storage tank, and uses hot water warmed by solar water heaters in the winter After that, hot water is stored in the hot water storage tank installed in the hot water storage tank space in the basement, warming the hot water storage tank space in the basement, and sent to the hot water storage tank space from the total heat exchange type exhaust fan at any level. The outside air is supplied to the basement from the gallery installed in the hot water storage tank space, mixed with the air of the low temperature air in the basement, and the air in the basement is supplied to each room through the duct for low temperature air operation. In the summer, the remaining hot water in the bath is not supplied to the hot water storage tank, but the outside air sent from the total heat exchange type exhaust fan to the hot water storage tank space is supplied to the basement from the galleries provided in the hot water storage tank space. And underground cooled by geothermal heat After being mixed with air inside, to an apparatus for performing the weak cold air operated underground room air is supplied to each chamber through the duct.

  Conventional room temperature adjustment in small houses has been using air conditioners in the summer and cooling and heating using energy such as electricity, gas, and oil in the winter. From the viewpoint, it is an urgent need to reduce CO2 emissions accompanying energy consumption, and reduction of energy consumption and further replacement with natural energy are urgently desired.

  Along with this, as a means of utilizing natural energy, what is currently widely used is a solar water heater (thermal efficiency 50-60%) and solar power generation (conversion efficiency 10-15%) using solar energy. However, in both cases, energy-saving technology that uses only solar energy is easily affected by the weather and cannot be used alone because of instability, and has been used in combination with other energy. There is a need for improvements.

  On the other hand, the underground 4 to 5 m underground maintains a stable temperature throughout the year, so that it is cooler than the outside air in the summer and warmer than the outside in the winter. For this reason, facilities that use geothermal heat have been experimentally constructed in large buildings and public facilities, but the method of use is to preserve the ice made in nature during the winter. In general, it is common to transfer the ice to a heat storage tank in the basement in the summer to make cold water, circulate the cold water to each room and cool it. Therefore, it was necessary to replenish the heat storage layer with ice, which was not suitable for small-scale housing.

Furthermore, a heat pump system that uses geothermal heat is also used to supply hot water in the home and to cool and heat the room, but a horizontal loop system (deep a 1-2 m deep moat in the ground, In order to obtain a heat source for a house with a floor area of 100 m ² , it is necessary to embed a 400 to 600 m heat collecting pipe, and a vertical loop system (ground) 2 holes are needed for digging 50-50m deep wells, and pipes for heat collection are buried in them, and it costs 3 to 5 million yen for general housing, and the heat pump is operated. There was a problem that the cost (electricity cost) was about 75% of that of an electric water heater using midnight power.

  In July 2003, the Building Standards Law was amended to require 24-hour ventilation of the room (to ventilate 0.5 times the volume of the room in one hour) as a “sick house measure”.

Therefore, the present applicant invented and applied for an “earth / solar system (two-layer type)” described in Patent Document 1 and capable of complying with the Building Standard Law. According to the present invention, two tanks, a water storage tank and a hot water storage tank, are buried in the ground, and heat exchange pipes that communicate with the 24 hour air supply pipes of each room from the outside air intake are provided in both tanks. Plumbing and filling the storage tank with rain water, ground water or tap water, filling the storage tank with hot water from the solar water heater, and operating the opening / closing valve provided in the heat exchange pipe in the summer, in the winter Using cold water in the storage tank that has been cooled with cold outside air, the outside air is passed through the heat exchange pipe in the storage tank, and the hot outside air is cooled and sent to each room, so efficient cold wind operation can be performed I can do it. In the winter season, warm water in the water storage tank that has been warmed by hot outdoor air in the summer is warmed to the low temperature water via the heat exchange vapour. Since it passes through the heat exchange pipe, it becomes possible to send warm air into each room.
Japanese Patent Application No. 2007-42895

  However, in the patent filed by the present applicant, two tanks, a water storage tank and a hot water storage tank, are required, which complicates the piping, increases the number of open / close valves, increases the price, and increases the cost. The construction period was also long.

Therefore, the present applicant invented and applied for the “earth / solar system (single layer type)” described in Patent Document 2. According to the present invention, in the lower part of the building, a concrete tank constructed integrally with the foundation of the building is constructed, the heat exchange pipe is piped in the concrete tank, and the rain water is laid in the concrete tank. Or, it is filled with tap water or groundwater, and the supply air from the total heat exchange type exhaust fan is led to the heat exchange pipe in the concrete tank, and in the summer, the supply air from the total heat exchange type exhaust fan is cooled by the underground heat. After heat exchange between the water in the concrete tank and the heat exchange pipe, it is cooled and then supplied to each floor via the air supply pipe.In winter, the hot water from the solar water heater is made of concrete. Circulate in the tank to make the concrete tank warm, and supply air from the total heat exchange ventilator to the heat exchange pipe in the concrete tank. After warming to heat exchange with the replacement pipe, by which the air supply to each floor through the supply pipe, it is possible to feed the hot air in each room.
Japanese Patent Application No. 2008-134783

  However, in the invention of Patent Document 2 filed by the present applicant, a concrete tank is required, so that the price is high and a construction period for construction is also long.

Therefore, the present applicant invented and filed an application of “Earth Solar System (Ground Heat Recovery Pipe System)” described in Patent Document 3. According to the present invention, there is provided a total heat exchange type ventilation fan installed in a room of a building without installing a vent hole to the outside at the foundation of the building and blocking the air inside the first floor under the outside air to be in a sealed state. Fresh outside air supplied to the inside is sent to the inside of the first floor under the building, and a plurality of underground heat recovery pipes with a U-shaped lower part formed on the foundation floor under the first floor, both ends of the floor below the foundation floor. It is buried in the ground so as to protrude into the section, a blower is attached to one end of the underground heat recovery pipe, and the air inside the first floor is sucked into the underground heat recovery pipe by operating the blower, and the underground The air sucked into the heat recovery pipe is warmed in the ground heat recovery pipe by the underground heat in the winter season, and further, the hot water warmed by the solar water heater is circulated in the hot water heat storage tank provided at the bottom of the first floor Let the air inside the first floor under the floor warm, and summer The hot water from the solar water heater is not circulated in the hot water storage tank provided at the lower part of the first floor, and the air cooled in the underground heat recovery pipe by the underground heat is supplied to the inside of the first floor, part 1 Air under the floor is supplied to the ceiling of each floor through a duct, and the air supplied to the interior of the ceiling is supplied to the room from the gallery installed in the ceiling of each room. In addition, it has become possible to send cool air, which was weakly chilled, into each room in summer.
Japanese Patent Application No. 2009-158863

  However, even in the invention of Patent Document 3 filed by the present applicant, when the rainy or cloudy day continues, the temperature of the hot water of the solar water heater does not rise, and the temperature difference between the rainy and cloudy day and the sunny day The problem that is large occurred. Furthermore, for a house with a basement, there are a number of problems such as the problem of the space of the hot water storage tank installed in the lower part of the first floor and the problem of the location where the underground heat recovery pipe is installed. It was practically impossible to make an earth / solar system (ground heat recovery pipe system) compatible with a house with a basement.

In addition, in the case of the geopower system described in Patent Document 4, which has been conventionally known as a building air-conditioning ventilation system that uses a geothermal heat exchanger, in the winter season, only the underground heat alone can produce a heating effect (even underground 5m) The medium temperature is around 18 degrees, so even if the outside air is warmed by underground heat, the temperature is only lower than that), and the price is high. .
JP2007-303693A

Furthermore, in the case of the OM solar described in Patent Document 5, which is known as a solar system using solar energy, an auxiliary heating device is required because the heating effect is reduced when rainy or cloudy days continue. There was a problem, and further, there was a drawback that cold wind operation was not possible in summer.
JP 08-005161

  In view of such conventional drawbacks, the present invention aims at harmony with nature, suppresses waste of artificial energy such as oil, gas, electricity, solar heat, hot remaining hot water in the bath, An object of the present invention is to provide a cooling / heating device with a low energy cost and a simple structure that adjusts the room temperature of a house by effectively using geothermal heat in the ground.

  In the invention according to Patent Document 1, Patent Document 2, and Patent Document 3 filed by the present applicant, the above-mentioned problems have occurred. Therefore, in our company, in the winter, the remaining hot water in the bath is newly used as a hot water storage tank in the basement. Invented a device in which hot water remaining in the hot water storage tank was poured into a hot water storage tank installed in the space, and at the same time, it was decided to launch a new product.

  In order to solve this problem, fresh heat supplied to the indoor side by a total heat exchange type ventilation fan installed in the room on each floor of the building is sent to the basement from outside, and a part of the basement Building a hot water storage tank space that partitions the space and installed a hot water storage tank. In the winter, hot water heated by a solar water heater is used in the hot water storage tank in the bath, and then the remaining hot water in the hot bath is stored in hot water The air in the hot water storage tank space is warmed by flowing it into the tank and allowing the hot water to be stored, and the warm water storage tank space heated in this way is supplied indoors from a total heat exchange type exhaust fan at another level. By sending fresh outside air, the outside air sent to the hot water storage tank space is warmed by the warm hot water storage tank space where the remaining hot water of the bath is stored, and the warmed outside air is provided in the hot water storage tank space The gallery After being supplied to the basement and mixed with the air in the basement warmed by the underground heat, the duct blower provided inside the ceiling of each floor is operated to enter the ceiling of each floor from the basement via the duct. It was sent to the room from the gallery installed on the ceiling to warm the room, and in the summer, the remaining hot water of the bath was not supplied to the hot water heat storage tank, and it was sent from the total heat exchange type exhaust fan to the hot water heat storage tank space. By supplying outside air to the basement from the gallery provided in the hot water storage tank space and mixing it with the air in the basement cooled by underground heat, by operating the duct blower provided inside each floor ceiling It is characterized in that it is sent from the basement to the ceiling of each floor via a duct and supplied to the room from the gallery provided on the ceiling to cool each room.

  According to invention of Claim 1, after using hot water from a solar water heater in a bath in winter, in the warm water storage tank in the warm water storage tank space provided in the partial space of the basement The hot water storage tank space can be kept warm even when rain or cloudy weather continues because the water has been poured and stored, and the energy of the remaining hot water in the hot bath that has been flowing through the drainage can be reused. It became possible to contribute to CO2 reduction and energy saving. Furthermore, outside air supplied to the indoor side from the total heat exchange type exhaust fan is sent to each of the basement and hot water storage tank space according to the level of the building, from the total heat exchange type exhaust fan in the underground room heated by the underground heat Heat to collect the underground heat in the entire basement by mixing the air in the basement and the warm air heated by the hot water storage tank in the hot water storage tank space and mixing them in the basement. It became possible to use as a layered space, and it was possible to collect and use the heat of the remaining hot water of the bath and the underground heat with inexpensive and simple equipment.

Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

   1 to 6 show an embodiment of the present invention.

  FIG. 1 is an exploded explanatory view of a house with a basement using a solar water heater, a hot water heat storage tank, and a total heat exchange type exhaust fan according to the present invention. Hereinafter, an air conditioning system using solar heat and underground heat will be described.

  FIG. 1 is an exploded explanatory view showing a house 1 with a basement in which an earth / solar system (basement-compatible type) is incorporated for easy understanding of the earth-solar system (basement-compatible type) of the present invention. The solar water heater 2 is installed on the roof 3, and a warm water storage tank space 35 surrounded by a partition wall 24 is constructed in the basement 18, and the warm water storage tank 14 is installed in the warm water storage tank space 35, This hot water heat storage tank 14 is provided with a remaining hot water pipe 31 for supplying the remaining hot water of the bath 26, and further, in the hot water heat storage tank space 35, the total heat exchange type exhaust fan 4 installed at any level. The outside air (outdoor outside intake air) is sent through the outside air introduction duct 30 and the outside air (outside outside intake air) sent into the hot water heat storage tank space 35 is sent from the gallery 15 in the direction of the arrow 22, 18 is supplied. Furthermore, the outside air (outside air sucked air) from the total heat exchange type ventilation fan 5 installed at another level is also sent into the basement 18 via the outside air introduction duct 27. The outside air (outdoor air sucked in) from the total heat exchange type ventilation fan 4 and the total heat exchange type ventilation fan 5 sent into the underground room 18 in this way is sucked from the louver 10 provided in the duct space 9 and supplied. It is supplied to each room via the duct 8.

  In the earth solar system (basement-compatible type) configured in this way, hot water heated by the solar water heater 2 is supplied to the bath 26 via the hot water pipe 28 and further used after being used in the bath 26. The hot remaining hot water is drained and stored in the hot water storage tank 14 via the remaining hot water pipe 31 by removing a drain plug (not shown) installed in the bath for the remaining hot water pipe 31 provided in the bath 26. It gets hot.

  With the configuration as described above, the cold air operation of each room in summer will be described with reference to FIG.

  First, a method for supplying outside air (outdoor air sucked air) supplied from the total heat exchange type ventilation fan 65 to the indoor side into the underground room A will be described. The room-side discharge air (contaminated room air) in the first floor room B is sucked into the total heat exchange type ventilation fan 65 and exhausted to the outside. At that time, indoor air exhausted by the total heat exchange type exhaust fan 65 (indoor discharge air) and outdoor air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type exhaust fan 65. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the underground room A via the outside air introduction duct 66. Similarly, the indoor side discharge air (contaminated room air) in the second floor room C is sucked into the total heat exchange type exhaust fan 103 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 103 (indoor discharge air) and the outside air supplied to the room (outdoor suction air) are heat-exchanged in the total heat exchanging ventilator 103. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the hot water storage tank space 77 via the outside air introduction duct 95. Furthermore, the indoor side discharge air (contaminated room air) in the third floor room D is sucked into the total heat exchange type exhaust fan 106 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 106 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchanging ventilator 106. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the hot water storage tank space 77 via the outside air introduction duct 99.

  In this way, by using the total heat exchange type ventilation fan 65, the total heat exchange type ventilation fan 103, and the total heat exchange type ventilation fan 106, when the indoor air that is cool in the summer is replaced (ventilated) with hot outdoor air. In addition, it is possible to minimize the rise in room temperature.

  Next, how the outside air (outdoor air sucked in) from the total heat exchange type ventilation fan 65 introduced into the underground room A in this way becomes a weak cold air in the underground room A will be described. In the basement constructed by our company, the height of the basement floor and ceiling slab is 2.8 meters in the standard specification, so when constructing a standard basement, there is a difference in the part where the basement stands up from the ground surface. When pulled, the depth from the ground surface to the lower surface of the pressure plate (in our case, the thickness of the pressure plate is about 300 cm) is approximately 2.8 meters. By the way, our showroom (with basement) in Adachi-ku, Tokyo measures the underground temperature of 1 meter, 3 meters, and 5 meters underground every day. The temperature of the middle 3 meters will be the lowest temperature of 14.7 ° C in April and the highest temperature of 20.6 ° C in October. The reason why the lowest underground temperature shifts in April to the lowest outside air temperature (around February) is because it takes time for the surface temperature to penetrate into the ground. The same is true for summer. By the way, the temperature of 3 meters underground in August in our showroom (with basement) in Taito-ku, Tokyo is about 19 ° C. Thus, since the temperature of the underground 3 meters in the summer is lower than the summer outdoor temperature, the air in the basement A is also cooled by the cold concrete in the basement. For this reason, the outside air (outdoor intake air) supplied from the total heat exchanging ventilation fan 65 to the basement via the outside air introduction duct 66 is mixed with the air in the basement A and becomes weak cold air. Similarly, the outside air (outside air sucked air) supplied from the total heat exchanging ventilation fans 103 and 106 to the hot water heat storage tank space 77 via the outside air introduction ducts 95 and 99 is sent from the gallery 72 to the underground room A in the direction of arrow 75. Is mixed with the air in the basement A and becomes a cool air.

  The outside air (outdoor suction air) cooled in the basement A in this way is sucked in the direction of arrow 71 from the duct suction port 73 by operating the blower 47, and passes through the air supply duct 50 to the third floor ceiling. 100 is supplied to the third-floor room D from the louver 49 and the louver 102 to cool the third-floor room D. Similarly, by operating the blower 54, the outside air cooled in the basement A (outside air suction air) is sucked in from the duct suction port 73 in the direction of arrow 71, and then passes through the air supply duct 55 to the second floor. Supplied to the ceiling 97 and supplied to the second-floor room C from the louvers 53 and 98 to cool the second-floor room C. Similarly, by operating the blower 59, the outside air cooled in the basement A (outside air suction air) is sucked in the direction of the arrow 71 from the duct suction port 73 and passes through the air supply duct 61 to the first floor. The air is supplied to the ceiling 93 and supplied to the first floor room B from the gallery 58 and gallery 94 to cool the first floor room B.

  In the summer, the hot water storage tank 76 installed in the warm water storage tank space 77 is not supplied with hot water remaining in the bath, and in the summer, the hot water storage tank 76 is not used.

  Next, the operation of the warm air in each room in winter shown in FIG. 3 will be described.

  First, a method for supplying outside air (outdoor air sucked air) supplied from the total heat exchange type ventilation fan 65 to the indoor side into the underground room A will be described. The room-side discharge air (contaminated room air) in the first floor room B is sucked into the total heat exchange type ventilation fan 65 and exhausted to the outside. At that time, indoor air exhausted by the total heat exchange type exhaust fan 65 (indoor discharge air) and outdoor air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchange type exhaust fan 65. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the underground room A via the outside air introduction duct 66.

  The outside air (outside air intake air) supplied to the basement A in this way is the same as that described above in our showroom (with basement) in Adachi-ku, Tokyo, in February of our showroom (with basement). The temperature of the underground 3 meters is about 16 ° C, which is warmer than the outside air, so that the concrete in the basement is warmed and the air in the basement A is also warmed. For this reason, the outside air (outdoor air sucked air) supplied from the total heat exchange type ventilation fan 65 to the basement through the outside air introduction duct 66 is mixed with the air in the basement A and becomes low-temperature air.

  Further, the indoor side discharged air (contaminated room air) in the second floor room C is sucked into the total heat exchange type exhaust fan 103 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 103 (indoor discharge air) and the outside air supplied to the room (outdoor suction air) are heat-exchanged in the total heat exchanging ventilator 103. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the hot water storage tank space 77 via the outside air introduction duct 95. Furthermore, the indoor side discharge air (contaminated room air) in the third floor room D is sucked into the total heat exchange type exhaust fan 106 and exhausted to the outside. At that time, the indoor air exhausted by the total heat exchanging ventilator 106 (indoor discharge air) and the outside air supplied to the room (outdoor intake air) are heat-exchanged in the total heat exchanging ventilator 106. At the same time, all of the sucked outdoor outside intake air (fresh air) is guided to the hot water storage tank space 77 via the outside air introduction duct 99.

  In this way, by using the total heat exchange type ventilation fan 65, the total heat exchange type ventilation fan 103, and the total heat exchange type ventilation fan 106, when warm air in the room in winter is exchanged (ventilated) with cold outdoor air. In addition, it is possible to minimize the decrease in the room temperature. By the way, on the Mitsubishi Electric Corporation homepage, the heat exchange function of LOSSNAY (total heat exchange type exhaust fan) is changed to “when the outside air temperature is 0 ° C, the room temperature is 20 ° C, and the temperature exchange efficiency is 75%.” It is described that when the air is ventilated with LOSSNAY (total heat exchange type exhaust fan), the temperature of the air of the outside air (0 ° C.) becomes 15 ° C. due to the action of the heat exchanger and is supplied into the room (fresh air).

  Further, in the winter season, hot water heated by the solar water heater 44 is used in the bath 89, and then the hot remaining hot water after being used in the bath 89 is supplied to the hot water heat storage tank 76 provided in the bath 89. For this purpose, a drain plug (not shown) for the remaining hot water pipe 111 is pulled out, so that the hot water is stored in the hot water storage tank 76 via the remaining hot water pipe 111. The remaining hot water in the warm bath 89 stored in the hot water heat storage tank 76 in this way warms the air in the hot water heat storage tank space 77. In addition, drainage of the remaining hot water in the bath that has overflowed from the hot water heat storage tank 76 and is cooled at the bottom of the hot water heat storage tank 76 flows in the direction of the arrow 114 via the drain pipe 113 and is drained into the drain groove 81.

  Thus, after using the hot water warmed by the solar water heater 44 in the bath 89, the hot remaining hot water after being used in the bath 89 is transferred to the hot water storage tank 76 installed in the hot water storage tank space 77 of the basement. The outside air (outdoor air suction air) supplied from the total heat exchange type exhaust fans 103 and 106 to the hot water storage tank space 77 by flowing and storing hot water is caused by the remaining hot water in the hot bath stored in the hot water storage tank 94. Then, it is further heated and supplied to the underground room A from the gallery 72 provided in the hot water storage tank space 77. The low-temperature air supplied to the basement A in this way is mixed with the air in the basement A to further warm the air in the basement A. And the outside air (outdoor suction air) warmed in the basement A in this way is sucked in the direction of arrow 71 from the duct suction port 73 by operating the blower 47, and the third floor via the air supply duct 50. Supplied to the ceiling 100 and supplied to the third-floor room D from the louver 49 and louver 102 to warm the third-floor room D. Similarly, by operating the blower 54, the outside air warmed in the basement A (outside air suction air) is sucked in the direction of the arrow 71 from the duct suction port 73, and passes through the air supply duct 55 to the second floor. Supplied to the ceiling 97 and supplied to the second-floor room C from the louvers 53 and 98 to warm the second-floor room C. Similarly, by operating the blower 59, the outside air warmed in the basement A (outside air suction air) is sucked in the direction of the arrow 71 from the duct suction port 73, and passes through the air supply duct 61 to the first floor. Supplied to the ceiling 93 and supplied to the first floor room B from the gallery 58 and gallery 94 to warm the first floor room B.

  Thus, in the winter season, after using the hot water heated by the solar water heater 44 in the bath 89, the hot remaining hot water after being used in the bath 89 is installed in the hot water storage tank space 77 of the basement. Even if cloudy or rainy days continue by flowing into the bath 76 and storing hot water, the hot remaining hot water after being used in the bath 89 is poured into the hot water storage tank 76 to store hot water. It is possible to warm the air.

  FIG. 4 shows a state in which the basement-equipped house 41 in the present invention is configured by next-generation energy-saving heat insulation. Regarding the heat insulation of the roof, the roof heat insulating material 120 (generally, urethane foam having a thickness of 160 mm) is applied to the inside of the roof. Regarding the heat insulation of the outer wall, the outer wall heat insulating material 121 (generally, urethane foam having a thickness of 75 mm) is applied to the inner side of the outer wall. As for the window sash, a heat insulation sash 122 of heat insulation grade 4 (next generation energy saving type) sold by each company is used. Regarding the heat insulation of the foundation, an outside foundation heat insulating material 123 (generally, a foamed polystyrene board having a thickness of 50 mm) is applied to the outside of the foundation concrete. In addition, the foundation outside heat insulating material 123 to be constructed outside the outer wall of the basement is constructed to a depth of about 10 cm from the ground surface. The reason for this is that when the foundation outer insulation 123 is installed on the entire outer wall of the basement, it is difficult for the underground heat to be transmitted to the basement concrete. However, regarding the type and material of the heat insulating material written here, for example, even if it is a polystyrene plate, the heat insulating effect changes due to the difference in density, so even the same manufacturer changes the thickness depending on the density In some cases.

  Regarding the heat insulation of the basement-equipped house 41 in the present invention, it is necessary to construct the next-generation energy-saving type heat insulation described in FIG. 4 in order to obtain the maximum energy saving effect.

  FIG. 5 is a front view, a plan view, an AA sectional view, and a BB sectional view of the hot water heat storage tank 131. The hot water heat storage tank 131 is formed in a water pillow shape by welding the ends of two rubber-like sheets (vinyl chloride sheet or the like) cut into a rectangle. Holes (not shown) for the intake port 138 and the drain port 135 are made in the upper rubber sheet 132 used for the upper part, and the rubber sheet is cut into a square shape (about 20 cm × about 25 cm in size). And a hole (not shown) in the hot water inlet of the remaining hot water in the bath is created in the center to create a welded portion 137, and the inlet 138 made of a PVC pipe is welded to the welded portion 137 with PVC.
