This is a continuation of International PCT Application No. PCT/EP2011/050078, filed Jan. 5, 2011 which claims priority to European Patent Application No. 10382014.8, filed Jan. 25, 2010, now granted application No. EP2354700 B1, the disclosures of which are incorporated herein by reference for all they teach and disclose.
TECHNICAL FIELDThis invention relates to tanks for storing water, and more specifically to tanks for storing pressurized water, such as hot sanitary water.
PRIOR ARTSystems and/or installations comprising tanks for storing pressure water for its subsequent use, such as for storing pressure water, which is subsequently used for domestic purposes, for example, are known in the prior art. Thanks to said storage, when a user turns on a tap or a shower to obtain hot water the water is hot immediately without the user having to wait until it is heated by means of a heater, for example. Such tanks can also be used to supply hot water to the heating system of a house for example. The water is generally heated by solar power systems (with the tanks forming part of a solar panel for example), though it can also be heated by heaters or equivalent means if necessary.
The tanks are generally made of stainless steel, and as the water is under pressure, it is desirable that the shape of the tank is such that there are no flat surfaces, as this would create the risk of the pressure exerted by said water being focused on a specific point, causing the tank to break or even to explode, for example. As a result, known solutions present a cylindrical tank, the diameter of which depends on the capacity given to the tank, which can pose a problem in the storage of large amounts of water due to the size it can occupy for example. These cylindrical tanks are not strong enough to withstand the pressure of the water stored inside them.
Document U.S. Pat. No. 4,637,375 discloses a tank for the storage of pressure water. This tank is cylindrical and comprises an intake through which pressure water enters it, and an outlet through which hot pressure water is evacuated from its interior for its distribution.
Document WO 97745250 A1 discloses a tank for storing pressure water, comprising a tank body formed by a plurality of substantially hollow and substantially tubular segments, the pressure water being stored inside said tubular segments. The tubular segments are joined each other by means of connecting walls that extend longitudinally and which comprise an opening through which the pressure water travels from one tubular segment to another.
DISCLOSURE OF THE INVENTIONIt is an object of this invention to provide a tank for storing pressure water, as described in the claims.
The tank for storing pressure water of the invention comprises a tank body in which the pressure water is stored, an intake through which pressure water enters it, and an outlet through which the pressure water is evacuated for its use. Said tank also comprises a plurality of substantially hollow tubular segments, which are disposed adjacent to each other and joined to each other and which are open on both sides, the pressure water being stored inside it. The tubular segments form the tank body, so that the tank has a substantially rectangular shape.
Hence, thanks to the tubular segments, a tank with the capacity to storage a large amount of water is created without it being of a size that prevents its use or installation in certain locations, such as in the walls of a house as a partition wall or in the roofs of houses, for example. Thanks to the tank of the invention, therefore, larger amounts of water can be stored in a simple way.
The tubular segments are open on both sides, the tank body being open on both sides, and the tank comprises at least one cover on each side of the tank body in order to close said tank body. Two adjacent tubular segments are joined to each other by means of a connecting wall that extend longitudinally, said connecting walls preventing a direct connection between the inside of two adjacent tubular segments, said tubular segments being communicated to each other through the covers. Each cover comprises a substantially semi-spherical section in order to cover one end of each tubular segment, and a wall in its interior to separate one semi-spherical section from the adjacent semi-spherical section, said wall comprising at least one through-hole through which the pressure water travels from one tubular segment to an adjacent tubular segment.
Thus, a rigid union between the tubular segments and the cover is achieved as said cover is attached to the tubular segment in the whole width of both the wall of said cover and the wall of said tubular segment, the communication between the different tubular segments not being influenced by the size of the passages (through-holes in this case) through which the pressure water passes from one tubular segment to another, providing flexibility to the design of the tank without losing rigidity since the size of said passage can be increased, if a better passage of water is required for example.
These and other advantages and characteristics of the invention will be made evident in the light of the drawings and the detailed description thereof.
The tubular segments 1 are joined by means of connecting walls 10, said connecting walls 10 insulating the inside of two adjacent tubular segments 1 one from the other, the tubular segments 1 not being directly communicated to each other. Said tubular segments 1 are open on both sides and the tank 100 comprises at least one cover 3 on each side of the tank body 2 in order to close said tank body 2 on both sides, the tank body 2 and said covers 3 forming a storage module 4 that corresponds with the tank 100 in the first embodiment of the invention. Thus, in said first embodiment the tank 100 comprises two covers 3 and a substantially rectangular shape.
Preferably, as shown in the embodiment of
In a second embodiment shown in
Preferably, the covers 3 and the tubular segments 1 are manufactured from the same material, so that they can be joined together easily by welding and the leakage of water in the connections is prevented. Naturally, other types of connections can also be used, although the connections have to be insulated to prevent water from escaping or leaking. The material used is also a thermoplastic material, which can be moulded to provide the shape of the tubular segments 1 and of the semi-spherical sections 30 of the covers 3, which support high temperatures without becoming deformed, and which support pressure such as that exerted by hot sanitary water. Preferably, the material used is PPSU.
These types of tanks 100 can be used in different installations, such as solar panel installations or even in installations where the tank 100 can be disposed in a house or an office. Thanks to its tubular and rectangular shape, it is possible to fit it in the wall of a house, as a partition wall for example, without it using up much space in the house and/or affecting aesthetic continuity. In this particular case, the tank 100 is covered with a conventional insulating material, the idea being to prevent the pressure water stored inside it from losing heat and negatively impacting on the room of the house by heating up in summer, for example.
