Abstract

The present invention refers to a valve for mixing hot and cold water, which may be used in a distribution system where the cold water flowing upon opening the shower will be distributed to the toilet tank or any other deposit. The system comprises a valve that prevents the hot and cold water from flowing and leads said water to a toilet water tank.

Description

HOT AND COLD WATER MIXER VALVE Field of the invention The present invention pertains to the area of valves, and more particularly. to a cold and hot water mixing valve. 5 Background A user regularly opens a hot water tap and lets the cold water flow, before the water comes out. Hot water. This causes several liters of water to be wasted, just because it is not at the desired temperature for the bath. Therefore, it is necessary to develop systems that allow saving water; 10 cold.

Typical valves for distributing hot and cold water comprise a first inlet coupled to a cold water tank and a second inlet to a hot water tank to receive the cold and hot water from its respective tank. The valves include a mechanism for controlling the flow and / or mixing of the cold and hot water. When the first inlet is incorrectly coupled to the hot water tank, and when the second inlet is incorrectly coupled to the cold water tank, hot water and cold water can be supplied wrongly.

; In this sense, the patent application US 2006037651 presents a mixing valve that includes a body having two entries in its. base.

This device consists of a rotating shaft moved through a knob. By moving the knob, the tree rotates and allows hot and cold water to mix inside and slide into an outlet duct. When the user wishes to mix all he has to do is turn the knob again. ' US patent application 20070023090 presents a hot and cold water mixing system consisting of three components, a coupler for hot water in the form of "Y" with a flow control valve on one side, a central coupler in the form "Y" with a flow control valve, and a "Y" cold water coupler with a flow control valve on the side opposite the hot water coupler. A unique configuration is derived by keeping the central coupling up. The system has been designed to mount hot and cold water faucets. This allows the water temperature to be kept constant and no adjustment is required while providing the full pressure of hot and cold water.

• US patent 1243999 presents a thermostatic hot water mixer. Cold water and steam are connected to a valve. entry. The thermostat comprises a metal diaphragm located in a cover filled with liquid. The steam is controlled for. release hot water A bar is connected to the diaphragm. An increase in temperature causes an expansion of liquid fluid within the diaphragm container and compresses it. This acts on the bar and closes the steam valve against the compression spring. The supply of cold water is constant and the steam supply varies to maintain the desired temperature. 5 Patent US 640593B1 presents a device for mixing hot and cold water. This device consists of a screw located in the hot water flow conduit. In this case, the cold water is installed in an internal mixing chamber. The mixing is carried out thanks to the fact that when the screw is activated, it starts sending hot water to the mixing chamber. The camera, in turn, is isolated from the hot water pipe by means of a disk-shaped membrane. The screw contains a system of springs that allow it to slide horizontally to open and close the flow of hot water. This sliding system allows the quantities of hot water desired by the user to enter, for subsequent mixing with cold water. 15 '| |'. . : "'|' ·; '' US Pat. No. 4286749 discloses a fluid mixing valve for mixing hot and cold water. Pressure means control the flow rate of high and low temperature fluids. The cold water flow rate is varied according to the flow velocity of the hot water. The cold water pressure changes 0 cause a change in the flow velocity of the hot water. The pressure ratio of both fluids is maintained by a predetermined value. A movable member is responsible for opening and closing the doors according to the recorded temperature.

Due to this problem with the mixing valves, there continues to be a need for valves that solve this problem. Therefore, the present invention provides a. new valve that allows mixing hot and cold water, so that water. cold that would be eliminated when opening a shower, now it will go to a deposit where it can be used for another purpose other than bathing.

Brief description of the figures The > Figure 1 is a perspective view of the water and cold distribution system, wherein (1) in the cold water inlet from a reservoir, (2) is a water heater,. (3) is the hot water pipe ,. (4) is a bathroom shower, (5) is the hot and cold water mixing valve, and (6) is the sanitary water tank.

Detailed description of the invention The present invention is relative is a mixing system of hot and cold water containing a mixing valve. The function of the valve is to divert the water that flows immediately through a shower. Said water is cold, since when the tap is open the hot and cold water remain in contact and by empathy the two temperatures tend to equalize; The temperature decreases when the water flows again and the water runs cold through the shower. The hot and cold water mixing valve, characterized in that it comprises a tubular metallic body in the shape of a cross having the function of housing a metallic tree containing at its lower end an elongated portion. This elongated portion is inserted over a groove that is in a hollow sphere; In turn, this hollow sphere contains two holes. One of these holes is located in the horizontal bottom in a position opposite to the slot. insertion; the other hole is located in position, vertical to the sphere. The mechanism of action is that when the user wishes to divert the flow of water, he turns a knob; said knob when operated mediatedé a. turn turns the tree in turn, this tree is connected by an elongation to a groove made in the sphere. The sphere contains two orifices in which each one of them coincides in diameter and position with two respective water flow channels.

When you do not want to divert the water, these holes do not coincide in position with their respective flow channels. The only rotation of the knob, as a consequence, the holes of the sphere coincide with the flow channels, and therefore the water flows towards the channel located in the lower part. Thus, this cold water will be conducted to a water tank for use in the toilet. Additionally, the knob contains a thermostat inside, which indicates the temperature of the water that will be discharged to the toilet tank.

The system of distribution of hot and cold water is composed among others, things of a system of conduction of hot and cold water based on pipes, a source of hot water (a gas or electric heater, or based on solar cells), a source of cold water (a cistern, or tank), a water tank located on a toilet, this deposit can be an additional one already installed on a toilet, and a thermostatic control system.
