Description

COMPACT FILTRATION BLOCK FOR POOL TANK DESCRIPTION The invention relates to the technical sector of the water filtration media of a swimming pool tank. It is known, to ensure the filtration of water from a pool tank, to use independent elements in the form of compact blocks that integrate, on the one hand, the filtering means and, on the other hand, the pumping means, for the aspiration and the retreat of water. Generally, those blocks comprise a compartment immersed in the water, shaped to be in communication with this water by means of at least one mouth known under the name of "SKIMMER". This compartment internally receives the different filtering means of all known and appropriate types. The other compartment receives the pumping means to allow the aspiration and retraction of the tank water by means of a system of appropriate conduits. The compartment that receives the pumping means is located outside of the pool tank. The two compartments can be joined by added elements or constitute a unitary set. In most cases, that block is formed in section to overlap the walls of the pool tank. Therefore, this block is intended to be added and assembled after the construction of the pool tank as such. In this way, the suction and return ducts between the filtration and pumping means pass over the upper flange of the wall element under consideration. This type of block can be illustrated by way of indication, but in no way limiting the teachings of the patent FR-8,318,248. There are also known panels or stairs shaped to comply with the functions of filtration, aspiration and retraction of the water and that are intended to be assembled with panels that constitute the whole pool of the pool. It is clear from this state of the art that the aspiration and retraction of the water from the pool tank, in combination with the filtering means, is effected either by means of added elements intended to be installed after completion of the operation. pool tank, either by means of elements intended to be integrated with the panels that make up the pool tank.

The problem that the invention sets out to solve is that of proposing an assembly that allows the aspiration and evacuation of the water from the pool tank in combination with the filtering means, which can either be added after the completion of the Pool tank, either be integrated at the time of completion of the pool tank. To solve this problem, an assembly in the form of a compact block of the type described above was conceived and put into place, that is to say, they present a submerged compartment in the water and intended to receive the filtering means and a compartment outside the tank, intended to receive the pumping means, and ducts ensure the connection between the filtering means and the pumping means, to ensure the aspiration and retraction of the water. So that this type of block could be used indifferently in overlapping on the walls of the pool tank, or integrated into the constituent panels of the pool tank, it was necessary to solve the important sealing problem between the two compartments, underlining that it is not conceivable that the water that is in the submerged compartment can pass in the outer compartment that receives the pumping means.

In this case, if the sealing problem is less important in the case of a block intended to overlap the walls of the pool, this is not the case when that same block is intended to be mounted in juxtaposition with the tank panels of the tank. pool, Indeed, in the case where the block overlaps the walls of the pool tank, the latter is -due to the presence of the suction and return ducts between the two compartments. In other words, the separation space between the two compartments is above the upper water level of the tank. On the contrary, if that block is mounted in combination with the adjacent panels of the pool tank, without therefore overflowing in height, it will be necessary to reduce the distance corresponding to the height of the free space between the two compartments, for the passage of the suction and return pipes. Consequently, a space of this type is practically at the water level of the tank with evident risks of the passage of water in the pumping compartment. FR-8.318.248. Taking into account the problem posed to solve and the limitations that must be respected: - the two compartments cross-sectionally delimit a profile in section that can overlap the walls of the tank of the pool; the filtration compartment in communication with the tank water, presents fixing arrangements with panels that constitute the walls of the pool tank. The two compartments are separated by a watertight wall to prevent water from entering the filtration compartment in the pump compartment. To solve the problem posed to ensure the tightness between the two compartments, the partition wall presents tight fitting arrangements with the suction and return ducts joining the filtering means and the pumping means. Advantageously, the splice arrangements are constituted, for each conduit, by a sleeve passing through the wall which has sealing and fixing elements in relation to said wall; the free ends of that sleeve, located on one side and on the other side of that wall, are arranged to allow the tight coupling of the conduits. Taking into account the total tightness between the two compartments, it is necessary to ensure the aeration of the compartment receiving the pumping means in order to avoid any overheating of the engine. To solve such a problem, the pump compartment presents aerating arrangements to cool the motor. Advantageously, the problem posed by the aeration of the pumping compartment is solved in that the aeration arrangements are constituted by a gutter formed behind the pumping compartment and in communication with the latter; this gutter is also in communication with the outside air. The two compartments are sealed by a removable cover. The cover has a plurality of perforations in order to connect the gutter with the outside air. To solve the problem posed of being able to perfectly integrate the block at the time of mounting the tank panel, the cover is profiled at its end located on the side of the filtration compartment, to ensure continuity with the curb of the pool tank. In the following, the invention is explained in more detail with the help of the figures of the attached drawings in which: Figure 1 is a perspective view of the mixed filter block according to the invention; Figure 2 is a schematic sectional view showing the assembly of the block in an overlapping position of one of the walls of the pool tank; Figure 3 is a sectional view of schematic character showing the assembly of the block in juxtaposition position with the constituent panels of the pool tank. Figure 4 is a sectional view according to line 4-4 of the. figure 3; Figure 5 is a longitudinal sectional view of the block; Figure 6, on a larger scale, is a partial sectional view showing the sealing arrangements at the level of the partition wall. In a known manner, the filtering block, designated as a whole by (1), comprises two compartments (la) and (Ib) arranged side by side one behind the other. The compartment (1) receives the filtering means (2) of any known and appropriate type. That compartment (the) is intended to be in communication with the water in the pool tank. This compartment (at least) has at least one entrance mouth or "skimmer" (3) disposed facially or otherwise, in order to allow water to enter the interior of the compartment (Ia) to subject it in a known manner to the filtering power of the media (2). The compartment (Ib) receives means (4), in particular in the form of at least one pump, to allow the suction and withdrawal of the water from the pool tank, in combination with the filtering means (2). The compartment (Ib) is intended to be placed outside the pool tank. As indicated in the preamble, the compact filtration block is shaped to allow, at will, either a assembly that is made after completely completing the pool tank, either at the time of completion of that tank, purpose of integrating with the panels that constitute them. For this purpose, the two compartments (la) and (Ib) delimit transversely, a profile in section that can overlap the walls of the tank of the pool (figure 2), in order to allow its added placement in relation to the walls (P ). In the illustrated example, the two compartments (la) and (Ib) have a free space (le) that corresponds practically to the thickness of the wall (P) of the tank of the pool, in order to be able to place the block on horseback on this last, thus allowing to bury the pump compartment (Ib), while the filtration compartment (the) is submerged in the water of the pool tank. However, it is not excluded that the two compartments (la) and (Ib) are together; the pumping compartment (Ib) is in this case, out of the ground, while the filtration compartment (la) is always submerged in the water of the pool tank. According to another characteristic, the filtration compartment (la) presents fixing arrangements with the panels (Pl) that constitute the walls of the pool tank. For this purpose, the opposite side faces of the compartment (1) have fixation pins (5) or others that can cooperate with the complementary arrangements that have assembly flanges of the panel (Pl). The pins (5) can advantageously be submerged in the thickness of the side walls of the compartment (la).

It follows that the block (1) constitutes a mixed block since it can be used, either in the case of a pool that already exists (figure 2), or at the time of the realization of a pool (figure 3). Taking into account this double possibility, it is convenient to handle the problem of the tightness between the two compartments (the) and (Ib), in order not to allow the water containing the compartment (the) to accidentally go into the pump compartment ( Ib). Therefore, it is necessary to provide between the two compartments (la) and (Ib), a communication space (6) allowing the passage of the suction (7) and cooling (8) conduits. In the case where the assembly of the block is arranged overlapped in the walls of the pool tank (figure 2), the problem of the tightness between the two compartments is less important, since in this overlapping position, the block is raised; The communication space for the passage of ducts (7) and (8) is located above the wall considered the tank of the pool (Figure 2). On the contrary, it is no longer the case when the whole of the block is intended to be assembled in juxtaposition with the panels (P) that constitute the pool tank. In this case, the block is lowered from a height corresponding to that of the communication space (6). In other words, for the same water level in the pool tank, the latter will tend to pass through the communication space (6). Taking into account this important problem of managing the water level of the pool tank, and having as objective that of maintaining its maximum, whatever the placement of the filtration block assembly, that is, in overlap or integration, the two compartments (la) and (Ib) are separated by a watertight wall (9) in order to avoid any accidental passage of water from the filtration compartment (la) into the pump compartment (Ib). This wall (9) presents tight fitting arrangements with the suction (7) and return (8) conduits that join, as indicated, the filtering means (2) and the pumping means (). As shown more particularly in FIG. 6, the splice arrangements are constituted by a sleeve (10) passing through the sealing wall (9). This sleeve (10) has a bearing collar (10a) which cooperates with one of the transverse faces of the wall (9), and on the other side of that wall, the sleeve (9) has a washer (1) that can be supported against the other face of the wall (9) in combination with a sealing gasket (12) under the action of a tightening nut (13). The two ends of the sleeve (10) present arrangements of the suction and return ducts (7) and (8) which are in two different parts (7a-7b) and (8a-8b). For example, the part of the conduits (7a) and (8a) connected to the pump, are end-connected to the corresponding sleeve, by means of a tight-fitting collar (14), which has a gasket (14a) to cooperate with a complementary circular rib (10b) of the sleeve (10). On the other side of the watertight wall (6), the other parts (7b) and (8b) of the suction and return ducts become integral with the free space (10c) of the sleeve, especially by gluing (figure 6) . Taking into account the tightness of the pump compartment (Ib), it is necessary to provide for its cooling in order to avoid any heating of the pump motor. For this purpose, the pumping compartment (Ib) is in communication, at the level of its rear part, with a gutter (Id) in communication with the outside air. The two compartments (la) and (Ib) are sealed by a cover (15) especially in two parts (15a) and (15b) corresponding to the suction compartment and the pump compartment, including the gutter (Id). Taking into account the problem posed by the aeration of the compartment (Ib) and the communication of the gutter (Id) with the open air, the part of the cover (15b) presents at the level of the gutter (Id), a plurality of perforations (15c). These technical provisions for the aeration of the pumping compartment are evident from the teachings of the patent application Fr ...

According to another feature, the cover (15), more particularly the part (15a) located on the side of the filtration compartment, is profiled to ensure continuity with the curb of the pool tank, when the block assembly is fixed in combination and in continuity with the different adjacent panels that make up the pool tank. Of course, the compact block assembly, as defined according to the features of the invention, can present any type of perfectly known arrangement, such as stair step, projector, access ramp, etc ... The advantages are set well manifest of the description; in particular, the possibility of using the filter block in an added manner in connection with the walls of an existing pool tank or of assembling it in combination and in continuity with the panels constituting the tank is emphasized and recalled. the pool.
