Description

“CONSTRUCTIVE ARRANGEMENT APPLIED IN HOT SET” [001] This utility model patent belongs to the field of hydraulic installations and was developed to allow the reuse of cold water that is normally wasted during heating, thus providing great resource savings. and natural resources involved in this process.

[002] As is well known in the art, water heaters - which may be electric, gas or solar-based - are generally located far away from showers and / or taps so that all water stored indoors from the piping that interconnects the heater and the point of consumption becomes cold or at room temperature and is therefore discarded when the hot water tap is opened. Depending on this distance, a significant amount of water is wasted until hot water begins to flow out of the tap / shower - adding up the water that has remained in the pipeline and the volume spent until the heater actually starts to flow. provide the water at the desired temperature.

Studies carried out on various types and sizes of buildings containing various heating systems have shown that the average waste in these cases is 12 liters of water per bath, which may vary more or less depending on local climatic conditions. If we consider a residence or apartment with three residents taking a daily bath each, there will be a waste of around 36 liters / day or 1080 liters / month of treated water - considering a building with 60 apartments under the same conditions' this will represent an approximate waste 65,000 liters / month of treated water, 1004] In view of these drawbacks and in order to remedy them, the device for reducing water waste in hot water installations has been devised and developed. The present invention is comprised of equipment provided with a set of mechanical or electrical valves, switches, thermostat, pressure switch and / or timer associated with a return pipe for cold water reuse during the period when the heating system raises the temperature. fluid to the predetermined minimum value.

Thus, if the user wishes to use cold water, before turning on the tap, he should set the switch t to the "cold water" position to allow immediate water to escape. Please note that in installations (new or not) where the device can be installed before the mixer receiving only hot water from the heater, it will not be necessary to use switch 1 to establish a cold or hot bath as the mixer is open. For cold water only, the device will not act and the equipment used will serve cold water.

[006] If the user turns the switch to the "hot water" position, when the tap is turned on, the water will only come out when the sensor detects that it is at the minimum set temperature - until this happens, the system directs the water flow to a pipe. which discharges the waste water for reuse at another location - which may be a lower building reservoir, or another existing or on-site reservoir - for subsequent routing of that water to the reservoir from which the building's hydraulic facilities are supplied, or for direct supply to other points of consumption that do not require water heating.

In addition, the equipment also allows to save water in a part of the bath in which normally the shower is not used the time to lather the body. At this time, if the user sets switch 2 to the "rinse" position, the assembly will open solenoid valve 1 allowing water to return to the reservoir - in this case, the water temperature remains heated as stipulated in the thermostat. To end the bath, the user returns the switch 2 to the "bath" position so that hot water flows back through the shower.

Thus, the presented device and system optimize the utilization of the water in all the possibilities of use involving its preheating, [009] The installation of the device / system can be done in a built-in or apparent way - in which case overlaps existing structures, thus allowing their use in new or existing installations. It can be used in residential or commercial buildings, shops, industries, hospitals, etc., or in any place where the heating system - whether electric, solar, gas, among others - is far from consumption points and can work in 110 or 220 Volts.

By way of illustration and for better understanding, the invention will be further described and detailed based on the accompanying figures, in which: Figure 1 schematically shows the normal situation of a wasteful installation ;

Figure 2 schematically illustrates an installation equipped with the proposed overlay box device for normal use in an existing installation;

Figure 3 illustrates a schematic flow diagram of the installation of the recessed or overlay box device, and Figure 4 schematically shows in side view the device in the overlay version.

It should be noted that the drawings presented are schematic and merely illustrative and not limiting, since the invention may contain various aesthetic and / or dimensional configurations without thereby departing from the scope of the intended protection.

According to the above figures, the equipment for reducing water waste in hot water installations, and said operating set object of the present invention is comprised of a housing (C) containing a thermostat. (1) provided with display, one pressure switch (2), two solenoid valves S1 (3) and S2 (4), one water temperature sensor (5) and two switches, one for the "cold / hot water" function (6) and another for the bath / rinse function (7) and manifold (8).

The thermostat (1) regulates the water temperature according to the preset made by the user. The pressure switch (2) - connected to the piping (9) from the mixer (M), which in turn receives the pipes of cold water (F) and hot water (Q), the latter from the heater (AQ) - controls the pressure of the water passing through the pipe (8) and, when detecting the passage of water when the mixer is opened, electrically supplies the thermostat that will operate the valves S1 and S2, while the temperature sensor (5) controls and checks the water temperature until the minimum limit set on the thermostat (1) is reached.

[0018] The following table shows the logical scheme of operation of the internal elements at each time of use of the system, and their possibilities of use (being F = closed and A = open): [0019] Based on the table above, If the "cold / hot water" switch (6) is selected for "cold water" and the "bath / rinse" switch (7) is set to "bath", the system will not check the water temperature by closing the solenoid valve 61 (3) which is connected to the return line (10) and opening the solenoid valve S2 (4) connected to the consumption point supply line (11) so that the user can use cold water or in room temperature.

When the "cold / hot water" switch (6) is selected for "hot water" and the "bath / lather" switch (7) is set to "bath", the system checks the water temperature by sensor (5) until its temperature reaches the minimum value set on the thermostat (1). Meanwhile the solenoid valve S1 (3) remains open so that cold water is routed to the return pipe (10), which will lead it to a reservoir (not shown) - which may be the building's lower reservoir or other specific reservoir. for storing and distributing discarded water - for later reuse. When the sensor (5) detects that the water temperature has reached the minimum value set in the thermostat (1), the assembly closes the solenoid valve S1 (3) and opens the solenoid valve S2 (4), allowing the water to warm skirt peto point consumption and be used peto user.

Therefore, the solenoid valve S1 (3) controls the return cold water flow as long as the water temperature does not reach the minimum set value. When such a temperature is reached, this valve (3) is closed, and the solenoid valve (2) is opened to control the flow of hot water, directing it to the tap, shower and / or any feeding point.

In another use mode, by setting the "cold / hot water" switch (8) to "hot water" mode and the "bath / rinse" switch (7) to "rinse" mode, the system continues control of temperature set at the thermostat (1) through the sensor (8), but opens the solenoid valve S1 (3) to return the still hot water to the reservoir while the user soaps, for example. To end the bath, it sets the bath / rinse switch (7) to the "bath" position and at this time the solenoid valve S1 (3) closes while the solenoid valve S2 (4) opens again, allowing the bath continue with still heated water.

It should be noted that the power supply (A) of the device may operate at 110 or 220 Volts and, in addition, some of the above components may be replaced (such as: the pressure switch may give rise to a pass sensor; thermostat and solenoid valves can be replaced by timed valves, etc.) to constitute lower cost devices without. thereby, escape the scope of the desired protection.
