| ClATN[S In this built-in automatic cleaning system, the auto-clean tubes (T7 to TU, Figure 1) made of either stainless steel or PVC, are systematically installed and embedded across the.base (width) of the swimming pool at regular intervals, dividing the swimming pool into sections (A, B, C, D and E, Figure 1). These auto- clean tubes have jet holes (T21, Figure 4) or jet slots (T22, Figure 4) allocated and spaced evenly and systematically along the whole length of the tubes which discharge hundreds of powerful jet streams across the length of the pool. In a sweeping motion, these jet streams discharge the pressured water evenly and systematically from Section A to B, to C and so forth (Figure 1) depending on the number of auto-clean tubes (T7 to TIl) in the pool and this number depends on the size of the pool, usually from 3 to 6 tubes, or more if needed. These auto-clean rectangular tubes (Figure 4), are embedded in the base of the pool with only 5mm exposed, revealing only the jet spray holes. As a result of this, it is safe for pool users to swim while the pool c\eans itself. At any one time, only 1 auto-clean tube is discharging the powerful jet sprays, thus one section at a time is cleaned, ensuring that the sediment and debris is systematically swept from one end of the pool to the other end (A to E. Figure 1), and disposed of into two suction sumps (T12 and T13) found at the base at the far end of the swimming pool (Figure 1). The debris is then collected into the strainer pot (T14). 2. The fluid passes from the strainer pot through the pump and motor (Tl, Figure 1) to the filtration unit (T2) where the sediment is retained in the filter. From the filtration unit, the filtered fluid goes through the inlets of the distributor (D16, Figure Z). 3. The self -operated distributor (Figure 2) uses turbine energy consisting of blades (impeller)(D15, Figure 2) and fluid, which drives the gears (D17, Figure 2) and the disc (D18, Figure 2) in the distributor. The disc in the distributor directs and controls the pressured fluid, introducing the pressured fluid through outlets (D19a to D19f , Figure 2) directly to the inlet pipes (T5, Figure 1) leading to the various auto-clean tubes (T7 to TIl, Figure 1), one at a time. Since this distributor (T3, Figure 1) uses its natural water pressure coming from the filter, no extra booster pump is needed. This distributor is made of PVC and is weather proof and can be placed anywhere inside or outside the pump room. 4. This invention can be used in a new or existing swimming pool of any shape or size. 5. This instant auto-clean invention is the most effective and the fastest cleaning system in existence today. It is not only fast, but efficient, safe and energy saving. It takes only 2 minutes for one whole cycle which repeats itself as long as filtration is on, without using any extra booster pump or motor, thus doesn't take up any more electricity since it runs on the water pressure of the swimming pool's pump/filter. Just one cycle improves the condition of the pool dramatically. 6. This innovative invention is a direct auto-cleaning system that eliminates the use of manpower to vacuum the swimming pool, without having to invest in vacuuming equipment, thus saving on manpower and equipment cost, and more importantly, gives the swimming pool owners more privacy and peace of mind. |
In order for the pool to be clean, you need manpower to do the vacuuming throughout the entire pool to make sure that all dirt and sediment is sucked up. This is a very slow and time consuming process just to get the swimming pool clean. A lot of pool-cleaning systems actually clean the pool randomly, leaving dirt and sediment behind. They also stir up the water and thus bring up the dirt and sediment, only to have these settle again after some time.
Every swimming pool is equipped with a filtration system, i.e. filter and motor/pump, with inlet and outlet connected to the swimming pool. The motor/pump pumps water into the filter which purifies the swimming pool water but this doesn't clean up the dirt and sediment at the bottom of the swimming pool. All swimming pools need to be cleaned daily depending on the condition (cleanliness) of the swimming pool. By manually cleaning the pool, a vacuum head with a vacuum hose and a long handle attached, is introduced to the base of the swimming pool. The other end of the hose is connected to the suction pipe. The vacuum head will suck up the dirt and sediment, which will be trapped in the strainer and filter. Other auto-clean systems require extra motor/pump or equipment for the cleaning process, thus taking up time, and no swimming is allowed during vacuuming. The entire pool cleaning system will normally take about 1 hour or more, and this causes interruption to the pool users, and incurs extra manpower and electricity costs.
The most common problem for pool owners is having a dirty pool and unreliable pool cleaners, causing the owners worry and stress.
This auto-clean invention will sweep the entire swimming pool within 2 minutes and continues on as long as filtration is in progress. The system does not need a booster pump, so no extra electricity cost is incurred. It is a built-in system, that eliminates vacuuming and thus saves on manpower and equipment cost and ensures peace and privacy to the owners. This invention allows pool users to swim without interruption, while the auto clean system gently sweeps the base of the pool in a systematic manner, completing one whole cycle within 2 minutes. This system makes sure that the swimming pool is in sparkling clean condition at all times.
DETAILED DESCRIPTION
HOW TfflS AMAZING AUTO-CLEAN DISTRIBUTOR WORKS
This entire cleaning process is controlled by the auto self-operated distributor (no electrical power required), which directs and controls the pressure fluid to the outlet of 6 pipes (T5) in sequence. One complete revolution is one cycle, lasting only 2 minutes and the cycles continue to operate until filtration stops. This device, (Figure 2 - distributor) works on its own by using its natural water pressure coming from the direction of the pump/filter, without using any extra booster pump. The water pressure will drive the impeller (D 15), the gears (D 17) and the disc (D 18) simultaneously, releasing pressured water directly to the outlet pipes(T4) and subsequently to the various inlet tubes (T7 to Tl 1) in sequence, as directed by the disc. The disc introduces the pressured water first to Inlet auto-clean tube (T7), followed by inlet auto-clean tube (T8), then on to inlet auto-clean tube (T9) in sequence until it reaches the last of the inlet auto-clean tube (Tl 1), which will be the completion of the cleaning cycle.
The distributor casing is made of PVC (weather proof) and it can be placed anywhere, inside or outside the pump room.
HOW THE AUTO-CLEAN TUBES WORK
The pool is divided into sections by the auto-clean tubes (T7 to Tl 1) which are made of stainless steel or PVC. The number of auto-clean tubes in the swimming pool depends on the size of the pool and can be anywhere from 3 to 6 tubes. These auto-clean tubes are installed and embedded at the base of the swimming pool, leaving jet holes (T21) or jet slots (T22) approximately 5mm above the floor level. These tubes are allocated and evenly spaced systematically across the width of the swimming pool, at equal intervals, dividing the pool into sections A, B, C, D and E (Figure 1). These auto-clean tubes (T7 to Tl 1) discharge hundreds of jet streams (T6) of pressured water evenly and systematically in a sweeping manner. The pressured water is in the form of spray discharged from the embedded rectangular tube through a thin jet slot, approximately lmm (Figure 4 - T22) or through hundreds of tiny jet holes approximately 5mm in diameter (Figure 4 - D21). Each section of the pool (A to E) is cleaned by jet sprays controlled by each auto-clean tube which gently sweep the dirt and sediment to the next section in sequence towards the far end of the swimming pool where 2 suction sumps (T12 and Tl 3) suck in the dirt which go to the strainer pot (Figure 14).. One complete cycle takes about 2 minutes. The cycle repeats itself, thus cleaning the pool non-stop as long as the pump/motor is in operation. The swimming pool remains sparkling clear at all times.
