Description

  The present invention relates to a structure for cooling and heating an internal space of a building structure such as a house, and in particular, positive energy discharged as waste heat from natural energy such as sunlight or an artificial system such as a cooling and heating device or a fuel cell. The present invention relates to a cooling / heating structure for storing various kinds of heat such as heat or negative heat with a relatively large capacity and effectively using the stored heat.

  Concrete is placed in the foundation part under the floor of the house, or a water tank is formed, and a container filled with water is further formed and used as a heat storage material. Several types of air conditioning systems for air conditioning (mainly heating) have been proposed as shown in, for example, the following patent documents.

JP 2004-347220 A JP 2007-056649 A JP 2012-013240 A JP 2012-220131 A JP 2009-250466 A

  Most of the systems represented by the above-mentioned patent documents have a structure in which a concrete layer forming the bottom surface of the floor is configured as a heat storage material (heat storage layer), and a blower system as a means for transferring heat to and from this heat storage material Or, there are many things that require a route for carrying a heat transfer medium such as a blow duct hot water pipe for carrying heat between the heat source and the heat storage material, such as a hot water pipe, and the heat storage material Therefore, it is necessary to bend the path in a complicated manner for effective transmission to the system, and the installation cost of the system becomes high. There is also a problem of leakage of the heat transfer medium due to pipe deterioration.

  As mentioned above, most of the heat storage means described in each patent document is concrete, and there is an example (Patent Document 5) that uses a heat storage layer filled with a liquid such as water as an exception. System construction, such as concrete placement work and water tank formation, has a major impact on the basic structure of the house. For this reason, the construction of a heat storage system is practically limited to the construction of new structures such as houses.

  In addition, when using a heat transfer medium such as water, it is necessary to specify the flow path of the heat transfer medium such as pipes, so the heat source that supplies heat to the heat transfer medium circulating and flowing through these paths is Those that can be connected to these circulation paths, such as electric heaters and solar water heaters, are limited to individual devices and equipment. For this reason, the operating status and economics of the system greatly depend on the properties of the heat source. For example, if the heat source is artificial, such as an electric heater, it is possible to supply heat stably, but the operating cost is high, and conversely, in the case of a solar water heater, the operating cost is low. However, there are problems such as being forced to drive unstablely depending on the weather.

  Furthermore, as a matter of course, the heat storage capacity of these systems is the product of the amount of heat stored per specific volume (heat storage performance) of the installed heat storage material and the volume of these heat storage materials, and cannot be increased beyond this. That is, when a water tank is formed in the basement as a heat storage material, or when concrete is used as a foundation structure of a house, it is practically impossible to increase the heat capacity of these heat storage materials after building the house.

    In addition, it is not always possible to say that the amount of heat possessed by these heat storage materials is sufficiently utilized for air conditioning in a house. In other words, the amount of heat in the concrete 7 and the water tank is not a little dissipated into the ground. Moreover, even if the heat insulating material layer is formed, the heat capacity possessed by these concretes and water tanks is not sufficient for the amount of heat required, and as a result, it is not more than an auxiliary heat source for various air conditioners.

  The present invention solves the above-mentioned problems of the prior art, and uses one or more water containers (hereinafter referred to as “cells”, including examples) filled with water having the maximum heat capacity as heat storage members. In the cooling and heating system, the cell is placed in the lower space of the space where the person lives (for example, the underfloor space in the case of a house) so that most of the cell surface is in contact with this space, and the whole cell is placed as a heat storage space. is there.

  More specifically, in the basic configuration of the present invention, a plurality of cells are arranged in the space to be the heat storage space, and the cells are suspended from the upper part of the space or supported by a support tool standing from the lower part of the space. Thus, each cell is positioned in the hollow portion of the space, and most of the surface of each cell is in contact with the space, and means capable of transferring heat to the space portion, such as a duct, a fan, etc. This is an air-conditioning system in which means for transferring heat such as air supply means, outdoor units and indoor units of air conditioners, and hot water pipes are arranged.

  The other configuration of the present invention is that the entire space in which the cells are arranged is configured as a heat storage space including the cells, so that the heat storage material has a larger capacity than in the past, and the cells are circulated in the cell by circulating water. It is a cooling and heating system that efficiently exchanges heat with external heat, stores heat in a relatively short time, makes the entire space a short-time and large-capacity heat storage means, and takes out the amount of heat in this space as warm air or cold air.

  According to another configuration of the present invention, the material constituting the cell is formed in a bag shape, and the cross-sectional shape thereof is substantially circular, substantially triangular, substantially quadrilateral, etc. according to the cross-sectional shape of the support member that supports the cell. It is an air-conditioning system configured to be able to change.

  Since the present invention has the above-described configuration, any heat that can be transmitted to the space where the cell is disposed, such as an artificial heat source such as electricity and gas, waste heat of various devices, a natural heat source such as solar heat, and the like. All are available, and the versatility of heat utilization is extremely high.

  In addition, because the space adjacent to the living space of people such as the underfloor space can be configured as a very large heat storage part including the cell, it is possible to store unnecessary heat for a long period of time and use this heat when necessary. It becomes possible.

  Furthermore, with regard to daily heat utilization, even if the heat source is only solar heat, for example, it is rainy or cloudy for several days, effective heating can be performed with a large amount of heat stored in fine weather. Therefore, it is possible to stably use unstable natural energy.

  Furthermore, by making the cell into a bag-shaped material, the length of the cell, the cross-sectional shape of the cell, and the number of installation can be freely selected. For this reason, it is possible to make the space the most effective heat storage space for any space shape, and for the house after construction by a relatively simple work such as a renovation work, a predetermined space. Can be used as a heat storage space.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

  1 and 2 are views showing the basic configuration concept of the present invention. In the figure, symbol H is a house which is a structure provided with this heat storage system. First, mainly in FIG. 1, reference numeral 1 denotes a floor surface formed by arranging floorboards, and a living space 2 is formed in the upper portion by the floor surface 1, and a floor space for storing heat (hereinafter referred to as “heat storage space”) in the lower portion. 3 is formed. 5 is a concrete slab that forms the bottom of the heat storage space 3, and 6 is a heat insulating material layer, which is formed outside the lower surface of the floor 1 and surrounding the heat storage space 3.

  Next, a symbol S is a slit formed in the floor surface 1 for allowing the warm air or cold air in the heat storage space 3 to flow out and inflow into the living space 2. The concrete slab 5 and the heat insulating material layer 6 are not essential components of the present invention. Although the illustrated slit S is shown as a simple opening, it is possible for those skilled in the art to freely select an opening / closing lid, a louver for controlling the outflow direction of air, or a fan.

  Reference numeral 4 denotes a heat storage tank that stores water, and includes a plurality of water storage tanks (hereinafter referred to as “cells”) (examples of the configuration are denoted by reference numerals 7a to 7e in FIG. 2). The heat storage layer 4 is a space that forms the heat storage space 3 by being hung from the back surface portion of the floor surface 1 or disposed on a support member disposed on the bottom surface of the heat storage space 3 as shown in each embodiment described later. It is comprised so that it may be arrange | positioned in the hollow part. Thereby, the surface of each cell is exposed to the heat storage space as much as possible.

  The arrow He is the heat supplied to the heat storage space 3 by the heat transfer medium. For example, the heat supplied by the hot water heated by the solar water heater, the cold supplied by the cold air cooled by water, etc. Or, heat storage by using waste heat from the outdoor unit of the air conditioning system, artificial heat sources such as warm or cold air from the indoor unit of the same unit, waste heat from the water heater, or a gas such as water or gas such as water. Any kind of heat can be used as long as it can be supplied to the space 3.

3, 4, and 5 show the arrangement state of each cell 7. First, as shown in these drawings, several types of suspension-type configurations are shown, followed by the installation-type configuration.
First, mainly a suspension member for suspending the cell 7 is shown in FIG. Reference numeral 8 denotes a support portion constituting the main part of the suspension member, which is made of a material having high thermal conductivity such as an iron plate or an aluminum plate, and has a substantially U-shaped cross section as shown in the figure. Moreover, the cell supported by this support part 8 is formed in a bag shape that is long in the depth direction as will be described later, and this bag-shaped container is filled and sealed with water.

  Reference numeral 9 denotes a hanging metal fitting. The illustrated hanging metal fitting 9 is substantially S-shaped, but the shape may be changed according to the purpose, such as C-shaped. FIG. 3 shows a state in which the suspension member is suspended and each cell supported by the support portion 8 is positioned in the hollow portion of the heat storage space 3. That is, the suspension member that supports each cell holds the suspension fitting 9 on the screw 12 attached to the large pull 11 that supports the joist 10 under the floor, and supports and arranges each cell at the above position.

FIG. 5 shows a modification of the configuration shown in FIGS.
First, a metal plate 13 is suspended from another support bracket 8 by means of another suspension fitting 14. This metal plate 13 has the following functions. For example, in the case of heat supplied by warm air, the temperature of the metal plate 13 is raised faster than the support portion 8 that contacts the cell 7. For this reason, radiant heat flows from the metal plate 13 to the support portion 8, and as a result, the cell 7 supported by the support portion 8 quickly heats and stores heat. Further, in this configuration, the hanging metal fitting 9 is a C-type, and the floor surface 1 is directly formed on the large pull 11 so that the floor cooling / heating can be performed directly by floor surface heat transfer.

6 and 7 show a second embodiment.
This embodiment is mainly intended to improve the workability of the heat storage layer 4 and adjust the capacity of the heat storage layer 4.

  In FIG. 6, by adjusting the width of the metal plate of the support portion 8, the cell support space can be expanded like the support portion 8A of FIG. 6B, and a large capacity cell 7A can be arranged. it can. Of course, a small capacity cell (not shown) can be arranged by reducing the arrangement space. FIG. 2A shows a state where the support portion 8 is attached to the latch member 15. Note that. Details of the attachment method are shown in FIG.

FIG. 7 shows a construction method of the support portion 8.
A retaining member 15 for attaching a support member (directly the support portion 8) is attached to the large pull 11 at approximately equal intervals in advance. Reference numeral 15 a denotes a stepped portion that engages with the side edge of the support portion 8. On the other hand, the metal plate forming the support portion 8 is formed in a flat plate shape, and the side edges in the longitudinal direction are bent to form the engaging portions 8a.

  For attachment, one engaging portion 8a of the metal plate is engaged with the step portion 15 of the latching member 15 (left side in the figure). Next, the metal plate is bent in the width direction (center in the figure), and finally the other engaging portion is engaged with the step portion 15a of the other latching member at a position facing the latching member. 8 is formed. The screw 16 is screwed into the hooking member 15 through the screw insertion hole 8b (see FIG. 6A) formed in advance in the metal plate, and the support portion 8 is fixed to the hooking member 15.

  FIG. 8 shows a modification of the above-described configuration. Specifically, this is a modification of the suspension member shown in FIG. The support portion 8 having the illustrated configuration is made of a material having high heat conductivity and air permeability, such as a metal mesh, expanded metal, or a so-called punching metal in which a large number of small holes are formed in a metal plate. Reference numeral 8B denotes a belt for reinforcing the support portion 8, and the hanging metal fittings 9 are respectively attached to the belt 8B. This configuration is configured to more efficiently enter and exit the supported cell.

FIG. 9 shows a third embodiment.
This embodiment shows a method of arranging the cell 7 with respect to the support portion 8. First, the constituent material of the cell 7 filled with a heat storage material such as water (which will be described with water as an example in the following examples) forms a water container which is the main constituent material of the floor heating system proposed separately by the inventors. A bag-like container is preferable (see Japanese Patent Nos. 5039301, 4442958, 3930368, etc.). This bag-like container has a structure in which a laminated material in which a plurality of layers of a synthetic resin layer and a metal foil layer are folded, and the side edges after bending are bonded by thermocompression, or both side edges of two sets of laminate materials are respectively A structure sealed by thermocompression bonding is used. Both configurations are extremely stable, and it has been proven that there are almost no accidents such as water leaks due to aging even if they are installed for a long time. It has also been demonstrated that the thermal conductivity of the internal water is very good, and that heat can be stored and dissipated effectively.
It should be noted that a liquid having a high specific heat comparable to that of non-added water, such as those obtained by adding a certain additive such as antifreeze to “water”, is also used as the heat storage material. Hereinafter, these heat storage materials will be described simply as “water”.

  FIG. 9 shows a method of arranging the bag 7 'constituting the cell with respect to the support portion 8. FIG. 5B shows a bag that constitutes the cell 7, and a bag 7 ′ having a structure in which both side edges are sealed is used among the above-described water container constituting bags. The bag 7 'is arranged vertically with respect to the support portion 8 so that the seal portion at the bag side edge is positioned vertically as shown in the figure, rather than being arranged so that one surface thereof is in close contact with the support portion 8. A groove 8c is bent in the depth direction of the central portion of the support portion 8, and when the bag 7 'is disposed, one seal portion of the bag 7' is sandwiched by the groove 8c.

In the above state, water is poured into the bag 7 'and filled with water, and then the water inlet (not shown) is sealed to form the cell 7 (see FIG. 1A). In this way, the two flat portions of the inflated bag 7 ′ are supported by the inner wall surface of the support portion 8, and the water pressure is prevented from acting on the seal portion in the direction of peeling it off. Can do.
Although not shown, the support portion is divided into two parts in the depth direction of the support portion 8, and a clamping member made of a flexible material such as rubber is disposed at the joint portion between the two divided portions. Then, one of the seal portions of the bag 7 'is held. If the bag 7 'is previously attached to the support portion 8 in this way, the bag 7' can be placed vertically with respect to the bag 7 'during construction, particularly when water is poured into the bag 7'. There is no need to continue to support, and workability is improved.

FIG. 10 shows a fourth embodiment.
This embodiment shows a stationary type arrangement arranged on the bottom surface of the heat storage space 3, for example, the surface of the concrete slab 5 of FIG. Reference numeral 18 denotes a cell support member (hereinafter referred to as a “stand”) formed in a triangular cross section, and the heat storage tank 4 (see FIG. 1) is connected by connecting a plurality of stands 18 accommodating and supporting the cells 7. Configure.

  The illustrated stand 18 is constructed by assembling three members (hereinafter referred to as “plates”) denoted by reference numerals 18a, 18b, and 18c. Each plate 18a, 18b, 18c can be selected according to the use such as a flat metal plate, the above-mentioned wire mesh, expanded metal, punching metal, etc. In addition, when configuring one stand 18, these differently configured plates are combined. May be used.

  An example of the construction of the stand containing the cell 7 is shown below. First, in FIG. 10B, one end of the two plates 18 a and 18 b is connected by the clamping member 16 and the bolt 17. At that time, one sealing portion of the bag 7 ′ is held by the holding portion 16 so that the bag 7 ′ before water injection is not displaced in the stand 18.

  Next, the 3rd plate 3c located in the upper part of the stand 18 is attached. Specifically, the connection portions 18a 'and 18b' formed by bending at the ends of the plates 18a and 18b are respectively disposed close to the connection portions 18c 'at both ends of the connection of the third plate 3c. The whole is formed into a stand 18 having a triangular cross section. A desired number of other stands 18 having the same configuration are connected to the stand 18 to form an integral heat storage tank. The heat storage tank formed in this way is disposed on the surface of the concrete slab 5 that forms the bottom surface of the heat storage space 3, for example.

  FIG. 11 shows a modification of the above configuration. The configuration shown in FIG. 10A is basically the same as the configuration shown in FIG. Reference numeral 30 denotes a holding member arranged in parallel with the concrete slab 5, and each holding portion 30 has a groove in the holding member 30 and each connection portion 18a ', 18b', 18c located at the lower end of each panel 18a, 18b, 18c. ′ (See FIG. 10) is fitted to integrate the stands 18 and the integrated stand is placed on the concrete slab 5.

  FIG. 2B shows a configuration in which the integrated stand 18 is arranged in a plurality of stages (two stages in the illustrated case) in the vertical direction. Specifically, the connection means of the panels 18a, 18b, 18c constituting the stand 18 is slightly different from the configuration shown in FIG. 10, and the connection portions 18a ', 18b', 18c of the panels 18a, 18b, 18c are slightly different. It becomes the structure using the connection material 19 for exclusive use which connects' (refer FIG. 10) mutually. The connecting member 19 is formed of, for example, hard rubber, plastic, aluminum, or the like, and the connecting portions 18a ′, 18b ′, 18c of the panels 18a, 18b, 18c with respect to the grooves formed in the depth direction of the connecting member 19, respectively. ′ Are respectively fitted in the grooves of the connecting member 19 to form the stands 18, a desired number of these stands 18 are connected, and the bags 7 of the respective stands 18 are filled with water, thereby integrating the heat storage tanks. 4 is configured. Reference numeral 22 denotes a space formed between the stands 18 and is a passage for heat transfer air (for example, hot air) that transfers heat to cells in the stand 18.

  In addition, if the fixing plate 21 is fixed by screwing the screw 20 to the connecting member 19 positioned at the upper part of each integrated stand 18, the connection of the panels of the respective stands 18 can be further strengthened. As a result, the strength of the entire heat storage tank 4 can be increased. With the above configuration, the water storage tank can be easily configured by simply fitting the connecting portions 18a ', 18b', 18c 'of the panels 18a, 18b, 18c into the grooves of the connecting member 19, respectively. It is. That is, since the work can be simplified even when the building is not newly constructed, the structure can be easily installed in the under-floor space of an existing house.

  The upper heat storage tank 4 ′ and the lower heat storage tank 4 in FIG. (B) are arranged so that the stands are parallel to each other. For example, the upper heat storage tank is rotated 90 degrees so that each heat storage tank is vertical. You may arrange | position so that it may cross | intersect seeing from a direction. Further, if the size of the arrangement space permits, it can be configured in multiple stages of three or more stages.

  FIG. 12 shows a fifth embodiment. The configuration of this embodiment is a configuration in which an air passage as a heat transfer medium is formed, and cells are arranged in close contact with the air passage. Reference numeral 23 denotes a duct member, which is formed, for example, in a substantially bowl shape as shown in the figure. As the constituent material of the duct member 23, for example, a structure basically similar to that of the support portion 8 of the suspension member as shown in FIGS. 4 and 6 can be used. That is, a metal plate, a metal net, an expanded metal, a punching metal, or the like can be used as long as it has a strength capable of supporting the load of the cell 7 filled with water described later.

  At the center of the top portion of the duct member 23, a protrusion 23a that functions as a partition plate is bent and formed in the depth direction of the duct member 23. The lower end edge of the duct member 23 configured in this way is fitted into the groove of the fixing member 24 arranged in parallel, and the plurality of duct members 23 are connected. In addition, the duct member 23 is fixed by bending a plate-shaped material at the time of attachment as in the case of forming the support portion 8 shown in FIG. The member 24 may be fitted and fixed.

  If the duct members 23 are arranged in this way, the bag 7 'is arranged in the space between the protrusions 23a of the roof (upper surface) of each duct member 23, filled with water and sealed. Such a cell 7 is placed in close contact with the roof of each duct member. In this case, if the seal portion of the bag 7s' is inserted into a substantially V-shaped groove formed by the adjacent duct member, it can also be used to reinforce the seal portion.

  In this configuration, the installation of the duct members 23 is easy, and a heat storage tank can be configured simply by placing the cells 7 on the respective duct members 23. Since the construction is highly configurable, the existing configuration is the same as in the previous embodiment. It can be easily implemented in other houses.

  In the duct member 23 at the right end of the configuration shown in the figure, the ridge 23a is formed low, and an additional plate is attached to the lower portion. Reference numeral 23a 'denotes an additional plate. A groove formed on one side of the additional plate 23a ′ is fitted to the protrusion 23a of the duct member 23 to be integrated with the protrusion 23a, and as a result, the protrusion 23 is raised.

FIG. 13 shows a sixth embodiment.
This embodiment has a configuration similar to that of the first embodiment shown in FIG. That is, the support portion 8 is fixed to the joists 10 while the support portion 8 is suspended from the joists 10 in the first embodiment.

  In the figure, reference numeral 25 denotes a support portion, which has a flat bottom surface as shown in the figure, and both side edges are formed in a substantially U-shaped cross section formed by bending approximately 90 degrees from the bottom surface portion. The material for forming the support portion 25 is also made of a material having high thermal conductivity, such as an aluminum material, an iron plate, or a punching metal or an expanded metal made of these materials, like the support portion 8 of the first embodiment. Both sides of the support portion 25 are fixed to the joists 10 on both sides by fixing means such as screws. The support portion 25 in this state is also filled with water as in the first embodiment. 7 are arranged respectively.

  If both side edges of the support part 25 are slightly expanded from the 90 degrees toward the upper part and the support part cross section is formed in an inverted trapezoidal shape, the support part 25 is inserted between the parallel joists 10. In this case, both side edges are tightly adhered and stabilized to both joists by the elasticity of the supporting portion constituent material, and the workability of mounting the supporting portion can be further enhanced.

In the case of this embodiment, the water bag forming the cell 7 is placed in each support portion 25 at the time when the large pull 11 is disposed, and is filled and sealed with water, or after the joist 10 is attached to the large pull 11. A method such as inserting a water bag between the joists and filling with water can be adopted, and workability can be improved.
Further, in the illustrated configuration, the support portion 25 is disposed between the joists 10, that is, disposed so as to be orthogonal to the large pull 11. For example, the space between the large pull 11 is parallel to the large pull 11. It is also possible to arrange so as to. In this case, the upper end of the opposing wall surface of the support portion 25 is bent outward, the bent portion is engaged with the large pull, and the support 11 is suspended between the large pull 11 with a screw or the like. It is effective to fix with.

14A and 14B show a seventh embodiment.
In this embodiment, the cell is housed and supported by a support portion placed on the floor side of the heat storage space.
In FIG. 2A, reference numeral 27A denotes a cylindrical support portion, 27B denotes a support portion having a substantially U-shaped cross section, and 27C denotes a support portion having a substantially V-shaped cross section. In the configuration of FIG. (A), these three types of shapes are shown by way of example. However, in construction, a heat storage tank is usually configured with only one type of support portion, and other shapes are supported as necessary. Part. For example, when a cylindrical support portion 27A is arranged and a space where the cylindrical support portion 27A cannot be arranged partially remains, a V-shaped support portion 27C is arranged in this space portion.

The supporting members 27A, 27B, and 27C are made of a material having high thermal conductivity such as an aluminum material, an iron plate, or a punching metal or an expanded metal made of these materials as in the supporting portion 25 of the above embodiment. In these support portions 27A, 27B, and 27C, cells 7 filled and sealed with water are stored and arranged, as in the above-described embodiment. Reference numeral 26 denotes a spacer disposed on the concrete slab 5, and each support portion 27 is placed, and a space through which a heat transfer medium such as warm air or cold air passes is secured under each support portion 27. Although not shown in the drawings, cells filled with water and sealed are arranged in the support portions 27A, 27B, and 27C.

In addition, the figure (A) is comprised so that a heat medium may pass in parallel with respect to the depth direction of 27 A of support parts.
On the other hand, the configuration of FIG. (B) is configured such that the heat medium passes perpendicularly to these support portions. Further, the shape of the support portion indicated by reference numeral 27D shows a shape formed in a substantially bowl shape in cross section, but is not limited to this shape, and is cylindrical or substantially U-shaped as shown in FIG. Or a triangular shape.
14 and FIGS. 3 to 12 have a structure in which the cell 7 including the bag 7 ′ is supported by the support portion 8, the stand 18, the duct member 23, or the like. For example, if the strength of the cells 7 itself can be maintained sufficiently, the structure for supporting these cells 7 can be eliminated and the cells 7 themselves can be suspended directly or as shown in FIG. May be placed directly.

FIG. 15 shows an eighth embodiment.
In the configuration shown in FIG. 9, the bag 7 'is arranged horizontally with respect to the support portion 8, that is, the seal portions at both ends of the bag 7' are horizontally opposed to each other, contrary to the third embodiment shown in FIG. Yes. The support portion 8 is formed deeper. Therefore, when the bag 7 ′ is filled with water, both seal portions are positioned considerably below the side wall of the support portion 8. As a result, the water pressure inside the bag 7 'acts so that the seal portion is in close contact with the side wall, thereby preventing the seal portion from peeling off. If there is no spatial restriction of the heat storage space 3 or restrictions on the structure of the house, this configuration is the most workable in terms of the arrangement of the bag 7 '.

FIG. 16 shows a ninth embodiment.
This configuration is effective when the depth of the support portion 8 cannot be increased too much in the horizontal arrangement of the bags.
In FIG. 4B, reference numeral 8 d denotes a seal portion locking body formed in the inner depth direction of the support portion 8. When the bag 7 ′ is arranged with respect to the support portion 8, the seal portion of the bag 7 ′ is inserted into the groove of this locking body. When water is poured into the bag 7 'in this state and the water is sealed as shown in FIG. 5A, the seal portion is securely held by the locking body 8d by water pressure. In addition, this seal part stopper 8d is made of a flexible material such as rubber rather than a material having high rigidity, and if it is configured to be deformed to some extent by the internal water pressure, the pressure bonding property of the seal part is improved. In addition, the seal portion can be protected from excessive bending (see FIG. 1A).
