Abstract

This patent application aims to present a device that allows the installation of central heating in buildings with a single pipe system without the need for another pipe system for hot water. It pertains to the field of civil construction and water-saving. It relates to a HOT-AND-COLD-WATER-SWITCHING TANK (18) and a WATER-REINTRODUCTION TANK (8). Both tanks are supplied by an upper, central device (23) for switching between the outlets for hot and cold water. The first tank is a tank (18) fitted after a bifurcation (38) of the single pipe, thereby producing a difference in water temperature between the two branches of the bifurcation. The second is the tank (8), which, after the bifurcation (38), captures the water that would go to waste and reintroduces that water into the water system. This tank (8) has additional space provided by a level-control valve (9) at one of the inlets (10) thereof, which sets the depth of the water within the tank to an intermediate level.

Description

HOT AND COLD WATER ALTERNATOR CIRCUIT IN

SINGLE PIPING

[001] This patent application aims to reduce the cost of installing more efficient water heating systems, such as solar and gas, in place of electric heating. It belongs to the field of construction and water saving and has the function of saving installation costs as well as saving water used in buildings.

[002] An imminent problem facing humanity is the lack of water and energy, especially that of electricity. International authorities are already on the alert and looking for alternative solutions. This application proposes a device to significantly reduce the cost of installing solar or gas heating and also, once installed, also reduce water waste. The mass adoption of solar or gas heaters has not yet been achieved due to the high cost of installation and the inconvenience that installation time promotes in the daily lives of families. It is hoped with this project to modify this scenario with great benefit to humanity.

[003] One of the largest expenses for electric power in homes is electric water heating for electric showers and electric taps. Most of the time, central heating systems, such as solar or gas-fired, are more economical. However, the installation costs of these systems are not cheap. A significant portion of the expense is due to the need to install two plumbing systems, one that conducts unheated water and one that conducts heated water. These two systems fall into end-use devices such as showers and taps that mix these end-use water collections. So there is a high civil construction expense for the installation of pipes and fittings. Paradoxically, the underprivileged economic classes, the vast majority of the population, feel the impact of these construction costs, and even with environmental awareness, cannot contribute to the adoption of more efficient means of energy use. In addition, a very large contingent of homes only have unheated water pipes. Modify the building to add one more water pipe system heated is not feasible for the vast majority of the population. If we succeed in getting a system that no longer needs to add a plumbing system (heated water pipeline), it can give access to solar or gas heating to millions of people who own a single plumbing system home (provided these pipelines are heat and pressure resistant material).

[004] Very few people would be willing to break walls to install an additional plumbing system, because in addition to the construction inconvenience, the previous construction investment is lost. And for popular new homes, it's hardly possible to have two water pipe systems.

[005] A home solution in single plumbing homes is known to consist of using a normal black-painted water tank externally associated with a float-shaped water outlet. The dark paint absorbs sunlight and slightly warms the water tank and the float water outlet captures heated water that concentrates on the surface of the reservoir. This allows for the use of a single water piping system but hinders the adjustment of the final water use temperature. Similarly, one might think that more professional heating systems could mix water centrally and upstream of a home's plumbing to pour it into the single plumbing. Even so, adjusting the temperature would still be difficult as mixing water would take time to reach water use points such as taps or showers and it would be necessary to discard water from pipelines that would remain in the pipelines so that the ideal temperature water would reach use.

In addition, the most complex system would be located at a time of difficult handling, tuning and maintenance. The solution proposed by this order adds other solutions that seek simplicity, ease of maintenance and water saving.

[007] If the solution presented by this application was used at the beginning of construction, houses could be built with a single unheated water system but with heat resistant plumbing. Thus, the house could initially use electric heating and later evolve to central heating without the need to add plumbing. Even if the owner wants to keep the heating only electric, the house would already be as it would have the potential to install central heating such as solar or gas This strategy would reduce people's resistance to solar or gas heating systems due to the high costs of installing dual hot and cold water piping systems. Using a single plumbing system with heat and pressure resistant material would be seen as an investment rather than an expense, a motivation that would increase people's adherence to more energy efficient systems with consequent environmental impact.

[008] The solution presented by the patent letter INTEGRATED CLEAN WATER RECOVERY SYSTEM AND HEATED WATER THERMAL ENERGY under numbering BR 10 2014 008516-5 is already known. This system saves water by capturing stagnant water from heated water pipes, however, this charter also presupposes two plumbing systems, one for heated water and one for unheated water.

Already the solution presented by this application captures water from normal pipelines and reintroduces that same water into the normal water use system itself, requiring no other specific piping system for heated water.

[010] The present solution is a hot and cold alternator reservoir and a WATER REINTRODUCTION RESERVOIR. The hot and cold water alternator reservoir is a device which allows the creation of a downstream water system with a temperature difference which allows a water mixer to obtain Ultimate ideal water temperature. Mix this to be performed very close to the place of use. A central water distribution system upstream of the single plumbing system which alternates heated and unheated water flows into a single outlet is also designed by a remote controlled water switching system. or locally. The WATER REINTRODUCTION RESERVOIR stores and replaces the collection of single-plumbing water (hot and cold water) in end use devices such as taps, showers or toilets for water savings. The figures whose descriptions below will further illustrate the solution proposed by this current application. Figure 1: Illustrates a central water switch upstream of the single pipeline that receives hot or cold building water and flows into a single water outlet.

Figures 2 to 5 illustrate arrangements of the hot and cold alternating reservoir (18).

Figures 6, 7, 8 and 11: illustrate arrangements of the water reintroduction reservoir (8) associated with the hot and cold alternating reservoir (18).

Figure 9 illustrates a water switch that toggles the hot and cold water position of a tap or shower type water mixer.

Figure 10: illustrates arrangement of the hot and cold alternator reservoir (18) with air removal system from the system.

[01 1] The descriptions for numbering of each figure are the basis for all figures.

As illustrated in Figure 1, a water switch (23) having cold water inlet (24) and hot water inlet (25) having an outlet (21) is illustrated. The switching system connects one of these sources (24 or 25) to the outlet (21) and feeds the final water pipes of buildings, and the channel (21) can connect either with the hot water source (25) or with the source. cold water (24). Switch 23 can also mix water from these inlets 24 or 25 and pour water at optimum temperature at outlet 21 which will supply the final pipelines. A manual or electronic system, computerized or not, local or remote can trigger this switch. This switch (23) may be located in the central pipeline of the building piping upstream of the single piping system.

[013] As shown in Figure 2, building water pipes (4) are pointed with their building wall outlet (6), water end-use devices such as taps or showers are shown (1). 2, 3, 13, 14 and 15) showing the tap wrench (2 and 13), another tap wrench (3 and 14) the water mixer tube (15) and the water outlet nozzle (1) .The hot and cold alternator reservoir components (18) and ducts (22, 27 and 39) are shown. The hot and cold water alternator reservoir (18) and ducts (22, 27 and 39) treat a reservoir (18) provided with an outlet duct (20) which communicates with a water inlet (3 and 14), a water mixer (13, 14 and 15) and a water inlet (39) ) receiving bifurcation water (38) from duct (27) receiving water from water pipes (4). Duct bifurcation (38) also having a water outlet (22) that connects with another water inlet (2 and 13) of a water mixing device (13, 14 and 15). The hot and cold alternator reservoir (18) is a water diluting reservoir (18) that stores and dilutes the heat of water before it reaches the end-use device (3 and 14).

According to what is illustrated in figures 1 and 2, follows the description of the operation of the circuit. In the phase when the whole circuit is in cold water mode, with the switch (23) also offering cold water at the outlet (21), the two water inlets on the mixer (15) will be receiving cold water through their respective inlets ( 13 and 14). In another phase, when the user needs hot water, the switch (23) is changed to provide hot water outlet through its outlet (21). Waste water is discharged from the tap (1) after opening the flow switch (2 and 13) until hot water reaches the mixer (15). Then by an arm (22) hot water is provided. The other arm (39) deriving from a fork (38) passes through the hot and cold alternating reservoir (18) which reduces the temperature of the incoming water by dilution. Both arms (22 and 39) provide hydrostatic pressure to move water through the ducts (20 and 22). In this phase, it becomes possible to have hot water at the inlet (2 and 13) and cold water at the inlet (3 and 14) of the mixer (1 and 15).

According to what is illustrated in figures 1 and 2, the description of the circuit operation is further followed. In a third phase, after gradually heating the hot and cold alternator reservoir (18) it may be necessary to change the switch (23) to provide cold water outlet through its outlet (21). Residual hot water is discharged from the tap (1) after opening the flow switch (2 and 13) until cold water reaches the mixer (15). Conversely to the previous phase, cold water is provided by an arm (22). The other arm (39) that derives from a fork (38) passes cold water to the hot and cold alternator reservoir (18) which increases the temperature of the incoming water by mixing with the already heated water inside. . Both arms (22 and 39) provide pressure hydrostatic to move water through the ducts (20 and 22). In this phase, it becomes possible to have cold water at the inlet (2 and 13) of the mixer (1 and 15) and hot water at the inlet (3 and 14) of the mixer (1 and 15). The alternation of these phases allows to offer water at various temperatures.

Still according to what is illustrated in Figure 2, the hot and cold alternating reservoir 18 may be in the form of a cylindrical duct or arranged in sequential reservoir modules. Modules or ducts arranged in parallel or in series.

Also as illustrated in Figure 2, the water mixer assembly (13, 14 and 15) can be regulated by electrical and mechanical systems in the form of a water mixing regulator module having computerized systems, sensors. and electronic circuits assisting automation. It is understood from the figures, and texts of this specification and claims that the water mixer assembly (1, 2, 3, 13, 14 and 15) may be replaced by that water mixing regulator module which controls the final water temperature. by dosing the pipeline water mixture.

[018] As shown in Figure 3, hot and cold alternating reservoir (18) with two outlets (31 and 32) at different heights allowing to select different temperature water collections according to need is illustrated. of user. An toggle switch (34) selects the most suitable water outlet (31 or 32). When warmer water is required the higher outlet (31) is used and when less warmer water is required the lower outlet (32) is used. Not only changing the height of the water outlet can give water output at different temperatures, but also changing the position of the outlet. For example, in a hot and cold water alternator reservoir (18) in the form of a cylindrical duct or arranged in sequential reservoir modules, the upstream or downstream water outlet may also be provided at different temperatures.

According to what is illustrated in figure 4 is illustrated hot and cold alternator reservoir (18) with two outlets (35 and 36) with a separate inlet (36) with own flow switch (37) which is added to the water mixer (1 and 15). This allows another way to adjust the water temperature. According to what is illustrated in figure 5 is illustrated hot and cold water alternating reservoir (18) with two inlets (29 and 30) with insertion points at different heights, which may also be different positions upstream or downstream. downstream of the water flow. This arrangement allows, by means of a selector switch (33), heated water between the upper and cold water by the lower one, increasing the temperature difference within the reservoir. This enhances the function of the hot and cold water alternator reservoir (18) because, as the function of this reservoir (18) is to create a water temperature difference between the two bifurcation pathways (20 and 22), it is interesting that the even have the largest temperature difference between your inlet and your water outlet. A flow toggle switch (33) allows switching between water inlets as cold or hot water flow is chosen. Water outlets 31 and 32 and selector switch 34 are analogous to those shown in FIG.

Still according to what is illustrated in figures 2, 3 and 4, variation of the ducts (22, 27 and 39) and bifurcation (38) is conceived being replaced by water inlet branches (22 or 39) inserted directly into the water pipeline (4).

[022] As shown in Figure 6, building water pipes (4) are pointed with their building wall outlet (6), water end-use devices such as taps or showers are shown (1). 2, 3, 13, 14 and 15) showing the tap wrench (2 and 13), another tap wrench (3 and 14) the water mixer tube (15) and the water outlet nozzle (1) . Also illustrated is a toilet (5) with the associated flush box (7), traditional flush box that stores water and supplies water to the toilet. A water reintroduction reservoir (8) is illustrated as a reservoir (8) having a water inlet duct (10) provided with a water flow level shut-off valve (9) at an intermediate height. reservoir (8) and provided with a flow switch controlled water inlet duct (16), both inlet ducts (10 and 16) with hydrostatic communication (11) with water piping (4), reservoir (8) located on the water flow line (11 or 12) upstream or downstream of the hot and cold alternator reservoir (18). A level valve (17) illustrates a mechanism for preventing water overflow. According to what still illustrates the figure 6, follows the description of the operation. The alternating phases between hot and cold water have the same operating principle as described for figures 2 to 5. However, when the switch (23) starts to offer hot instead of cold water at the outlet (21), the residual water instead of being thrown away by the water outlets (1), this cold water is taken to the water reintroduction reservoir (8) after opening the key (19) and occupying the additional space of the water reintroduction reservoir (8) above the limit established by the level valve (9). When hot water reaches the points near the use devices (2 and 13) the cold water is already stored in the water reintroduction reservoir (8) and is now available for use in the other inlet port (3 and 14) of the device. using the alternating hot and cold water reservoir (18).

According to the further illustration of Figure 6, the description of the operation for another phase follows. When the switch (23) starts to offer cold instead of hot water at the outlet (21), the hot waste water that remains in the pipes (4), instead of being thrown out by the water outlets (1), that water passes to be led to the water reintroduction reservoir (8) after opening of the key (19) to occupy the additional space of the water reintroduction reservoir (8) above the limit established by the level valve (9). When cold water reaches the points near the use devices (2 and 13) hot water is already stored in the water reintroduction reservoir (8) and is now available for use in the other inlet port (3 and 14) of the device. using the alternating hot and cold water reservoir (18).

[025] As shown in Figures 6, 7 and 8, variations in the arrangement of the WATER REINTRODUCTION RESERVOIR (8) are illustrated. While Figure 6 and Figure 8 show the WATER REPLACEMENT RESERVOIR (8) upstream of the hot and cold alternator reservoir (18), Figure 7 shows the WATER REPLACEMENT RESERVOIR (8) downstream of the alternator reservoir hot and cold water (18). In addition, figure 8 illustrates variation of the WATER REINTRODUCTION RESERVOIR (8) which has as its water inlet (12) at the reservoir water outlet (12) itself (8), having flow control switch (19).

As shown in Figure 9, a water outlet toggle switch (26) is illustrated in which a duct (12 or 22) feeding one side of the switch (2 and 13) is fed to the other side of the water. key (3 and 14) and vice versa. This output inversion is designed for better user usability with a hot water tap and cold water tap in mind. When inverting the water output from hot to cold or vice versa, by the main switch (23) the user may be confused because it reverses the laterality of the control keys (2 and 3). This water outlet toggle switch (26) allows one side of the tap (1, 2, 3, 13, 14 and 15) to be continuously warmer than the other.

According to what is illustrated in figure 10, there is illustrated hot and cold alternating reservoir (18) with air removal system from the system. As air intrusion occurs in running water, air may be trapped in the hot and cold alternating reservoir (18) interfering with the water temperature diluting property. In this case, an air removal system is designed which consists of introducing an air outlet (41) into the upper region of the reservoir.

(18) having control switch (40) of this outlet, which air outlet (41) may have communication duct (41) with the mixer duct (15) which communicates with the water outlet (1) of the device. This air outlet through the tap nozzle allows no water to leak into the room, and the water flows into the sink itself.

[028] As shown in Figure 11, a deviation key is illustrated.

(19) for lower reintroduction water reservoir (8) and ducts (11) that derive from bifurcation (38) and connect to inlets (10 and 16) of the water reintroduction reservoir (8).

According to what is illustrated in figures 6, 7, 8 and 11, a unified water reintroduction reservoir reservoir (8) and hot and cold alternating reservoir reservoir (18) are formed as a single reservoir.

[030] Water temperature regulation system is designed which has temperature sensors at strategic points (1, 6, 8, 1 1, 12, 13, 14, 15, 18, 21, 22, 23, 24, 25 or 26) may be associated with switching (2, 3, 9 13, 14, 19, 23 or 26) electromechanical. In any arrangement it can be used in the control keys, manual keying or electro mechanical, and can be controlled electrically, electronically or electronically, in embedded systems or in traditional control systems such as microcomputers, smartphones, smartwatch, tablets or technologies. wearable. The control can be done by wireless communication or proximity sensor, and can be mediated by light energy, infrared light, led, sound, electromagnetic waves, sound waves, heat, ultrasound, wifi or bluetooth.
