1. Construction of whirlpool

The term "upper", "lower" and "lateral" and other terms used to describe the relative positions of the components of pools or whirlpools according to the invention refer to the pool or whirlpool in its inflated vertical position and which they define a water cavity (as shown, for example, in Figure 3). The terms pool and whirlpool are used interchangeably in the following description, where a whirlpool is a particular type of pool that may include an aerated water supply.

With the following description of the drawings and the specific embodiment, the invention will be described in more detail. According to Figures 1, 2 and 3, the inflatable pool 100 in the present invention comprises the upper wall or panel 10, the lower wall or panel 20, the inner surrounding or the side wall 106, the outer side or surrounding wall 108 and a plurality of laminated reinforcement or interval elements 120. The interval or reinforcement elements 120 may also be walls or panels.

The diameter of the outer side wall 108 is longer than that of the inner side wall 106, and the outer side wall 108 is offset out of the inner side wall 106, and a circular channel structure. The outer side wall 108 surrounds the inner side wall and can be substantially concentric with it.

The upper wall 102 is annular, and is connected to the upper part of the inner side wall 106 and the outer side wall 108.

The lower wall 104 is connected to the lower part of the inner side wall 106 and to the outer wall 108. An air chamber 110 is generated by the upper wall 102, the lower wall 104, the inner or inner wall 106 and the outer wall or external 108.

The laminated walls 120 are arranged vertically in the air chamber 110 annularly; and are connected to the inner wall 106 and the outer wall 108 by suitable coupling techniques, such as, for example, high frequency coupling (or welding), hot coupling (e.g., melting or welding) or adhesion (e.g. glued). A gap 122 is formed between the top of the laminated elements 120 and the upper wall 102. A gap 124 is formed between the bottom of the laminated elements 120 and the bottom wall 104.

According to Figure 4 and Figure 5, the laminated wall 120 comprises a pattern or screen layer 130 formed by a porous open pattern of interwoven or interwoven threads or fibers (e.g., a fabric or a fabric having an open weft ) and two tie layers 132. The two tie layers 132 are joined to the upper and lower surface of the first layer 130, respectively, to hold the first layer 130. The tie layer or layers 132 may be made of PVC ( polyvinyl chloride), TPR (thermoplastic rubber), EVA (ethylene vinyl acetate) or fabric.

According to Figure 6, the laminated layer 120 may also comprise a tie layer 132, and the pattern layer 130 is attached to the tie layer 132.

According to Figure 7, the laminated layer 120, the outer wall 108 and the inner wall 106 can be connected by suitable coupling techniques, such as, for example, high frequency coupling (or welding), hot coupling (p eg, fusion or welding) or adhesion (eg, glued).

According to Figure 8, the laminated interval wall 120, the outer wall 108 and the inner wall 106 can be connected via a connecting element, strip, wall or panel in a transient manner, that is, the laminated element 120 is connected to the element of connection 90 via, for example, high frequency coupling (or welding), hot coupling (e.g., melting or welding) or adhesion (e.g., bonding), then connection element 90 is connected to the inner wall 106 and the outer wall 108 through high frequency coupling (or welding), hot coupling (e.g., melting or welding), or adhesion (e.g., bonding).

The embodiments shown in the figures in more detail will be described below and initially in reference to Figures 1-3, an inflatable pool or hydromassage pool 100 is shown that includes an upper wall 102, a lower wall 104, an internal wall or inner 106, and an outer or outer wall 108. The upper wall 102 is an annular wall and is connected to the upper ends of the inner wall 106 and the outer wall 108. The lower wall 104 is also an annular wall and is connected to the lower ends of the inner wall 106 and the outer wall 108. The diameter of the outer wall 108 is larger than the diameter of the inner wall 106. The upper wall 102, the lower wall 104, the inner wall 106 and the External wall 108 of the whirlpool or pool may be constructed of polyvinyl chloride (PVC), thermoplastic rubber (TPR), ethylene vinyl acetate (EVA), thermoplastic polyurethane elastomer (TPU), or Other suitable materials.

The whirlpool or the pool 100 includes an inflatable air chamber 110 formed between the upper wall 102, the lower wall 104, the inner wall 106 and the outer wall 108. The air chamber 110 includes one or more suitable air vents (not shown) to inflate and deflate the air chamber 110. In certain embodiments, the air chamber 110 may inflate at a relatively high pressure, greater than about 0.8 psi. For example, the air chamber 110 may be inflated at a pressure of about 0.9 psi, 1.0 psi, 1.1 psi, 1.2 psi, 1.3 psi, 1.4 psi, 1.5 psi, 1.6 psi, or more. Such pressures may be approximately 1.5 or 2 times greater than the pressures used to inflate traditional inflatable products.

The whirlpool 100 also includes a water cavity 112 formed by the bottom wall 104 and the inner wall 106.

Within the air chamber 110, the pool 100 also includes a plurality of internal tension, interval or reinforcement elements or structures 120 that maintain the shape of the pool 100 when the air chamber 110 is pressurized. The tension structures 120 can improve the resistance of the pool 100, by allowing the air chamber 110 to withstand relatively high internal pressures, as explained above, while providing comfort to the user sitting in the pool or the whirlpool 100 .

As shown in Figures 1 and 2, the tension structures 120 are arranged vertically and radially in the air chamber 110 in an annular pattern. As shown in Figure 3, each tensioning structure 120 can be coupled to the inner wall 106 and to the outer wall 108, as explained below with reference to Figures 7 and 8. In addition, each tensioning structure 120 may be separated from the upper wall 102 and the lower wall 104 to define an upper hole 122 in relation to the upper wall 102 and a lower hole 124 in relation to the lower wall 104.

With reference to Figures 4-6, each tensioning structure 120 may include a porous layer or sheet 130 and one or more layers or tie sheets 132 attached (eg, laminated) to the porous layer 130. In the embodiment illustrated in Figure 5, the porous layer 130 is sandwiched between two tie layers 132, with the tie layers 132 attached to both the upper surface and the lower surface of the porous layer 130. In the illustrated embodiment of Figure 6 , the porous layer 130 is attached to a single joint layer 132, with the single joint layer 132 attached to the upper surface 160 or the lower surface 162 of the porous layer 130.

Except for the upper hollow 122 and the lower hollow 124 in the tension structure 120, the tension structure 120 may have a generally rectangular shape, as shown in Figure 4. In this embodiment, the porous layer 130 includes an outer perimeter generally rectangular 150 formed by the edges 152a-d, and the joining layer 132 includes a generally rectangular outer perimeter 154 formed by the edges 156a-d. The bonding layer 132 may encompass the entire porous layer 130, as shown in Figure 5, so that the outer perimeter of the bonding layer generally overlaps the outer perimeter of the porous layer. It is also within the scope of the present description that the bonding layer may encompass a part of the porous layer.

The porous layer 130 can be formed from a plurality of ligaments or elements of structure 134 that define a plurality of holes or pores 136 between them, as shown in Figure 4. When the air chamber 110 is pressurized, the elements of structure 134 can be placed in tension to help maintain the shape of the whirlpool 100. Adjacent structure elements 134 can be separate regular intervals to provide tension structure 120 with substantially constant tensile strength.

Each pore 136 of the porous layer 130 may be enclosed or completely surrounded by elements of the intersection structure 134 in a 360 degree range. A plurality of pores 136 may be located completely within the outer perimeter 154 of the tie layer 132 to facilitate bonding to the tie layer 132, as described below. It is also within the scope of the present description that other pores 136 may be located outside the outer perimeter 154 of the joint layer 132. The size and shape of each pore 136 may vary depending on the thickness and orientation of the surrounding elements of the structure 134. The porous layer 130 may also include, for example, a plurality of open spaces 158 that are partially surrounded by elements of structure 134 and partially exposed along the outer perimeter 150.

In the illustrated embodiment of Figure 4, the elements of the structure 134 are arranged in a grid pattern, which includes a first set of separate and parallel structure elements 138 and a second set of separate and parallel structure elements 139 In this grid pattern, the first set of elements of the structure 138 are transverse to the second set of elements of the structure 139, so that the first set of elements of the structure 138 intersects with the second set of elements of the structure. structure 139. In Figure 4, the grid pattern is rotated approximately 45 degrees from a horizontal axis to resemble a framework, so that the first set of elements of structure 138 slopes upward from the horizontal axis (e.g. approximately 45 degrees from the horizontal axis), and the second set of elements of the structure 139 is inclined downward from the horizontal axis ontal (p. eg, approximately -45 degrees from the horizontal axis) and is substantially perpendicular to the first set of elements of structure 138. In Figure 4, diamond-shaped pores 136 are formed spaced apart between adjacent elements of structure 134. Adjacent pores 136 may also be inclined up and down in relation to the horizontal axis.

According to an illustrative embodiment of the present description, the porous layer, pattern or screen 130 may be constructed by a mesh, fabric or screen with interwoven threads, fibers or wires as individual structure elements 134. Certain embodiments use fibers of a polyester, nylon or cotton As shown in Figure 4, each element of structure 134 may include a first terminal end 170 located at an edge (e.g., edge 152a) of the porous layer 130 and a second terminal end 172 located at an edge opposite (e.g., edge 152c) of the porous layer 130.

As explained above, each tensioning structure 120 can be coupled to the inner wall 106 and the outer wall 108 through suitable coupling techniques, such as, for example, high frequency coupling, hot coupling (e.g., melting, welding) or adhesion (e.g., glued). In the illustrated embodiment of Figure 7, the tension structure 120 is directly coupled to the inner wall 106 and the outer wall 108 along a seam 142. In the illustrated embodiment of Figure 8, the tension structure 120 is indirectly coupled to the inner wall 106 and the outer wall 108 by the use of intermediate connection layers 140. More specifically, the tension structure 120 is coupled to the intermediate connection layer 140 through a first seam 144, and the layers Intermediate connection 140s are coupled to the inner wall 106 and the outer wall 108 through a second seam 146. As shown in Figures 7 and 8, the seams 142, 144, 146 may be located along the edges opposite (eg, edges 152a, 156a and edges 152c, 156c) of tension structure 120. Turning to Figure 4, seams 142, 144,146 are shown extended in a vertical direction along d and the edges of the right side 152a, 156a, of the tension structure 120 to join the tension structure 120 to the adjacent inner wall 106 and along the edges of the left side 152c, 156c of the tension structure 120 to join the tensioning structure 120 to the adjacent outer wall 108, for example.

According to an illustrative embodiment of the present description, the elements of the structure 134 are oriented transversely (ie, not parallel) to the seams 142, 144, 146. In Figure 4, the elements of the structure 138 are inclined sideways to side in vertical direction. In this embodiment, as the vertical seams 142, 144, 146 and any line parallel to the vertical seams 142, 144, 146 pass through the tension structure 120, the vertical line will intersect at least one pore 136 or open space 158 between the elements of the structure 134. In other words, there is no vertical line that passes completely through the tension structure 120 along an element of the structure 134 without intersecting at least one pore 136 or open space 158 adjacent to the element of the structure 134. In Figure 4, the elements of the structure 138 are also oriented transversely to any horizontal line that is perpendicular to the seams 142, 144, 146. As explained above, the elements of the structure 138 are tilted up and down in the horizontal direction. In this embodiment, as any horizontal line perpendicular to the vertical seams 142, 144, 146 passes through the tension structure 120, the horizontal line will intersect at least one pore 136 or open space 158 between the elements of the structure 134. In In other words, there is no horizontal line that passes completely through tension structure 120 along an element of structure 134 without intersecting at least one pore 136 or open space 158 adjacent to the element of structure 134.

To facilitate secure connections between the tension structure 120, the inner wall, the outer wall 108 and the optional intermediate connection layers 140, the materials used to construct these adjacent layers may be the same or otherwise compatible. For example, if the inner wall 106, the outer wall 108 and the optional intermediate connection layers 140 are constructed of PVC, TPR, EVA or TPU, at least a part of the corresponding tensioning structure 120 can also be constructed of PVC, TPR , EVA or TPU. In embodiments in which adjacent layers are fused through the use of high frequency radiation, for example, compatible materials may have equal or similar melting points to ensure that the materials melt, mix and form secure connections. According to an illustrative embodiment of the present description, at least the joint layer 132 of the tension structure 120 may be constructed of a compatible material. The porous layer 130 of the tensioning structure 120, on the other hand, can be constructed of a different, potentially incompatible material (eg, of greater fusion), potentially stronger, because the pores 136 in the porous layer 130 can admit the joining adjacent compatible materials (e.g., one or more tie layers 132, the inner wall 106 of the whirlpool, the outer wall 108 of the whirlpool and / or optional intermediate connecting layers 140) a through the pores 136 in the porous layer 130. For example, the joint layer 132 of the tension structure 120 can be constructed of a compatible material such as pVc, TPR, EVA or TPU, while the porous layer 130 of the structure of tension 120 may be constructed of a fabric or screen.

In order to further prevent said water flow towards the air pump 232, the illustrative air duct 230 also includes a first check valve 260, a drain valve 280 and a second check valve 310. The first check valve 260 and the second check valve 310 can operate simultaneously to provide double protection to the air pump 232, so that if one check valve does not work, the other check valve can do the job. As shown in Figure 16, the first check valve 260 is disposed between the discharge side 238 of the air pump 232 and the first tube portion 250. The second check valve 310 is disposed along the third tube portion 254, more specifically under the first air outlet tube 242 of the third tube portion 254 and above the second air outlet tube 244 of the third tube portion 254.

The first check valve 260 is shown in Figures 17 and 18. The first check valve 260 includes a first housing 262 that is coupled to the air pump 232 and the first tube portion 250 and defines an internal cavity 264. The First check valve 260 also includes a first valve core 266 having a stem 268, a head 270 and a hemispherical sealing piece 272 coupled to the head 270. The first check valve 260 further includes a first elastic spring 274 that interacts With the first valve core 266, the first elastic spring 274 wraps the stem 268 of the first valve core 266 with one end positioned against the head 270 and the other end positioned against the first housing 262.

In operation, the first valve core 266 moves longitudinally through the internal cavity 264 of the first housing 262 between a sealed or closed position and an open position. In the sealed position, the sealing part 272 of the first valve core 266 extends towards the supply cavity 246 and is sealed against the surface of the valve seat 248, as shown in Figure 18. In the open position , the sealing part 272 of the first valve core 266 leaves the supply cavity 246 and separates from the surface of the valve seat 248.

The first housing 262 may also include a drain valve 280 coupled to a drain hole 282 from the first housing 262, as shown in Figures 17 and 18. The drain valve 280 includes an upper housing 284 having a surface of Uneven or undulating upper valve seat 286 and a lower housing 288 having a lower valve seat surface 290. The upper housing 284 and the lower housing 288 cooperate to define an internal drain cavity 292 in fluid communication with the drain hole 282. In certain embodiments, the drain hole 282 of the first housing 262 may be internally threaded and the upper housing 284 may be externally threaded to be screwed to the first housing 262. The drain valve 280 also includes a drain valve core 294 which has a stem 296, a flat head 298 that has a holding groove 300, and a piece Circular seal 302 placed in the clamping slot 300. The drain valve 280 also includes an elastic spring 304 that interacts with the core of the drain valve 294, the elastic spring 304 wraps the stem 296 of the core of the drain valve 294 with one end positioned against the head 298 and the other end positioned against the lower housing 288.

In operation, the drain valve core 294 moves longitudinally through the internal drain cavity 292 between a sealed or closed position and an open position. In the sealed position, the sealing part 302 of the drain valve core 294 is hermetically sealed against the surface of the lower valve seat 290. In the open position, the sealing part 302 of the drain valve core 294 moves away from the seat surface of the lower valve 290 and the flat head 298 of the core of the drain valve 294 moves towards the seating surface of the uneven upper valve 286.

When the air pump 232 is on, the air generator set 234 operates and directs the pressurized air from the suction side 236 of the air pump 232 towards the supply cavity 246. Upon reaching the first check valve 260, the air drives the first valve core 266 through the internal cavity 264 to the open position, in which the sealing piece 272 is separated from the surface of the valve seat 248 and the First elastic spring 274 is compressed. With the first check valve 260 in the open position, the air from the supply cavity 246 enters the first housing 262 and exits through the internal cavity 264. At the same time, the drain valve core 294 of the drain valve 280 is moved down by the effect of the air pressure in the sealed position, in which the sealing part 302 is sealed against the surface of the lower valve seat 290 and the elastic spring 304 is compressed. When the drain valve 280 is in the sealed position, the air pump 232 can operate normally.

When the air pump 232 stops, the air pressure in the first check valve 260 disappears, and the first elastic spring 274 returns and drives the first valve core 266 to the sealed position, in which the sealing piece 272 is sealed against the surface of the valve seat 248. With the first check valve 260 in the sealed position, the water in the whirlpool 100 is prevented from reaching the air pump 232. At the same time, the pressure The air spring disappears in the drain valve 280 and the elastic spring 304 returns and drives the core of the drain valve 294 up to the open position, in which the sealing piece 302 of the core of the drain valve 294 moves away from the lower valve seat surface 290 and the flat head 298 of the drain valve core 294 moves toward the uneven upper valve seat surface 286. When the drain valve 2 80 is in the open position, any fluid that may be present in the first housing 262 can drain from the drain hole 282, through the internal drain cavity 292, and into the outside environment.

The second check valve 310 is shown in Figures 19 and 20. As mentioned above, the second check valve 310 is arranged along the third tube portion 254. More specifically, the second check valve 310 is arranged between an upper section 312 and a lower section 314 of the third tube portion 254, where the upper section 312 increases in diameter in a downward direction and the lower section 314 increases in diameter in the downward direction.

The second check valve 310 includes a second valve holder 320 having a circular location ring 322, a hollow location rod 324 located in the location ring 322, and one or more openings 326 corresponding to the openings 328 in the section lower 314 to fix the second valve holder 320 to the lower section 314 of the third tube portion 254, as p. e.g., with screws (not shown). The second check valve 310 also includes a second valve core 330 having a rod 332, a head 334 with a platform or lower stop surface 336, and a hemispherical sealing piece 338 coupled to head 334. The second valve retention 310 further includes a second elastic spring 340 that interacts with the second valve core 330, the second elastic spring 340 wraps the stem 332 of the second valve core 330 with one end positioned against the head 333 and the other end positioned against the second 320 valve holder.

In operation, the second valve core 330 moves longitudinally through the location rod 324 of the second valve holder 320 between a sealed or closed position and an open position. In the sealed position, the sealing piece 338 of the second valve core 330 is hermetically sealed against the upper section 312 of the third tube portion 254, as shown in Figure 20. The sealing piece 338 can produce a contact of line with the upper section 312 of the third tube portion 254 in the sealed position. In the open position, the sealing piece 338 of the second valve core 330 moves away from the upper section 312 of the third tube portion 254 until the lower stop surface 336 of the head 334 rests on the location rod 324 of the second valve holder 320. Due to the line contact produced between the sealing piece 338 and the upper section 312 of the third tube portion 254 in the sealed position, the sealing piece 338 can be freely separated from the upper section 312 of the third tube portion 254 without an adhesion phenomenon, even if the second check valve 310 has not been used for some time, the useful life of the second check valve 310 is increased.

When there is no air or water present in the third tube portion 254, the second check valve 310 moves to the sealed position, in which the sealing piece 338 of the second valve core 330 is hermetically sealed against the upper section 312 of the third tube portion 254 by the effect of the second elastic spring 340. Because the upper section 312 of the third tube portion 254 narrows in an upward direction, the seal between the sealing piece 338 of the second valve core 330 and the upper section 312 of the third tube portion 254 becomes progressively tighter as the water pressure of the whirlpool 100 increases.

When the air pump 232 is on, the air reaches the second check valve 310 and drives the second valve core 330 down through the location stem 324 of the second valve holder 320 to the open position, in which the sealing piece 338 is separated from the upper section 312 of the third tube portion 254 and the second elastic spring 340 is compressed. With the second check valve 310 in the open position, air flows through the stem of location 324 of the second valve holder 320 and the whirlpool 100.

The control system 200 may have at least three modes of operation, which include: (1) an inflation mode, (2) a deflation mode and (3) an aeration or bubble mode. Instead of having to buy several parts of a device to perform these individual functions, the user can rely on the control system 200 to perform these functions, which can save space and costs. The user can select the desired mode by using the control panel assembly 208. These operation modes are described below.

In the inflation mode, the control system 200 can direct the air from the discharge side 238 of the air pump 232 towards the inflation tube 242 and towards the air chamber 110 of the whirlpool 100 to inflate the pool of hydromassage 100.

Inflation mode may also involve covering or closing aeration pipe 244.

In deflation mode, the control system 200 can extract air from the air chamber 110 of the whirlpool 100 through the deflation tube 240 and to the suction side 236 of the air pump 232 to deflate the pool of hydromassage 100, as shown in Figures 21 and 22. The deflation mode may involve coupling an extension tube 370 to the deflation tube 240 to increase the length of the deflation tube 240 for coupling to the air chamber 110 of the whirlpool 100. In other modes of operation, the suction side 236 of the air pump 232 can extract air from the surrounding atmosphere.

In the aeration or bubble mode, the control system 200 can direct the air from the discharge side 238 of the air pump 232 towards the aeration pipe 244 and towards the water cavity 112 of the whirlpool 100 to create Massage air bubbles in the whirlpool 100. The aeration mode can be achieved by covering the inflation tube 242 with the sealing cover assembly 360 to close the inflation tube 242 and opening the aeration tube 244. As shown in Figures 23 and 24, the whirlpool 100 may include an air transport tube 380 that communicates with the aeration tube 244 and extends through the outer wall 108, through the air chamber 110 and through the inner wall 106 towards the water cavity 112.

Additional sealing sleeves 772 may be used to couple the air transport tube to the outer wall 108 and / or to the inner wall 106 of the whirlpool 100 in a sealed manner.

The air transport tube 780 can direct air directly to the water cavity 112 of the whirlpool 100. The air transport tube 780 can also indirectly direct air to the water cavity 112 of the whirlpool 100 through of the spray nozzles 762. In the illustrated embodiment of Figures 39-40, the air transport tube 780 extracts the air from the surrounding atmosphere, directs the air through an annular and flexible connecting tube 782, and injects the air in the air hole 768 of each spray nozzle 762 by the suction force of the water flow through the spray nozzle 762. The air in the air transport tube 780 is mixed with the water in the nozzle of spray 762 to spray jet water into the water cavity 112 of the whirlpool 100. The flexible nature of the connection tube 782 can allow the deflated whirlpool 100 to be folded for storage and / or transfer.

It is also within the scope of the present description that the air transport tube 780 can communicate with an air pump (e.g., air pump 232 of Figures 15-18), as noted earlier in the section "Making the bubble". In this embodiment, the air transport tube 780 can also supply massage air bubbles to the whirlpool 100.

Returning to Figure 27, the controller (not shown) of the control system 500 can ensure that the electrical current of the control system 500 is kept below a predetermined limit, such as a standard domestic limit of 13 A to 16 A In one embodiment, the controller can limit the power supply to one or more units of the control system 500 when the jet water pump 534 is activated, and the controller can restore the power supply to the other units of the power system. control when the jet water pump 534 is deactivated. For example, the controller can automatically limit the power supply to the heating unit (not shown) to approximately 50% or less when the jet water pump 534 is activated, and the controller can automatically restore the power supply to the 100% heating unit when the jet water pump 534 is deactivated. The controller can further limit the power supply to the heating unit to 0% when both the jet water pump 534 and an additional air pump are activated.
