ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to boilers and, more specifically, to a compact apparatus positionable within any room of a structure for heating or cooling potable water supplied to that room wherein the heating or cooling of the water supply is selectively engaged based upon the temperature of the water desired by a user.
The device includes first and second water tanks and a controllable valve connected therebetween. The first water tank has a conduit for receiving water pumped from a main source of water and a conduit providing egress to the outlet to which it is connected. A heating device is contained within the first water tank along with a sensor for controlling the heating device. In addition, the first tank has a cooling sensor and conduit for extracting cold water from the second tank for delivery back to the first tank.
The second water tank is separated from the first water tank, and includes a water cooling device formed of an encircling refrigerant cooling coil connected to a compressor, a fan and a gas radiator. Cold water is selectively provided to the first water tank through a conduit connecting the first and second water tanks based upon the setting of a cooling thermostat having a sensor within the first water tank. In addition, the second water tank has a controllable valve connection to the first water tank for extracting water therefrom and delivery to the second tank for cooling prior to being returned to the first tank. A pump is connected to the second water tank for use in returning water back to the first tank. The use of the pump allows water to be supplied at a desired temperature to an outlet to which it is connected.
2. Description of the Prior Art
There may be other devices and methods employed for reducing the temperature within a building's water supply however none of these devices or methods are able to provide water of a desired temperature and pressure to an outlet such as a faucet or toilet connected thereto while also being compact in size and easily stored within the room to which the water is supplied. Furthermore, while these units may be suitable for the particular purpose to which they address, they would not be as suitable for the purposes of the present invention as heretofore described.
SUMMARY OF THE PRESENT INVENTION
The present invention relates generally to boilers and, more specifically, to a compact apparatus positionable within any room of a structure for heating or cooling potable water supplied to that room wherein the heating or cooling of the water supply is selectively engaged based upon the temperature of the water desired by a user.
A primary object of the present invention is to provide a temperature selective water supply device that will overcome the shortcomings of prior art devices.
A further object of the present invention is to provide a temperature selectable water supply device able to provide a supply of water having a user selectable temperature control to an outlet, e.g. a faucet, water tap or toilet, to which it is connected.
Another object of the present invention is to provide a temperature selectable water supply device which is easy to install and able to replace a conventional boiler positioned within a room of a structure and thereby provide both cooling and heating of water provided thereto.
A yet further object of the present invention is to provide a temperature selectable water supply device able to connect with a conventional pre-existing water tank to thereby provide water of a desired temperature to a desired outlet throughout the year regardless of the weather or air temperature.
A still further object of the present invention is to provide a temperature selectable water supply device able to switch between heating and cooling modes of operation by simply activating a switch.
An even further object of the present invention is to provide a temperature selectable water supply device having a first water supply tank and a second cold water tank.
A still further object of the present invention is to provide a temperature selectable water supply device having a first water supply tank including a device for heating the contents thereof and a second cold water tank having a device for cooling the contents thereof.
A yet further object of the present invention is to provide a temperature selectable water supply device having a first water supply tank and a second cold water tank, wherein the first water supply tank includes a device for cooling the water in the first water supply tank to a selectable temperature by injecting the contents of the second cold water supply tank into the first tank until the desired water temperature is obtained.
Additional objects of the present invention will appear as the description proceeds.
An apparatus for one of heating and cooling water provided by a water supply system to an outlet in a structure is disclosed by the present invention. The apparatus includes a main water tank including an inlet conduit for receiving water from a water supply tank connected thereto and an outlet conduit for supplying the water to the outlet connected thereto. The apparatus also includes a water refrigeration tank connected to receive water from the main water supply tank for cooling to a desired temperature. A heating device is connected to the main water supply tank for heating the water therein and a cooling device is connected to the water refrigeration tank for cooling the water received thereby. A return conduit is connected between the water refrigeration tank and the main water tank for returning the cooled water to the main water tank for mixing with the water therein and thereby cooling the water. A hot water thermostat is connected to the main water tank for measuring a temperature of the water therein and activating the heating device to heat the water when the measured temperature is below a first predetermined adjustable value. A cold water thermostat is connected to the cooling cycle for measuring a temperature of the water within the main water supply tank and activating the cooling device when the measured temperature is above a second predetermined adjustable value.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
