Benefits of technology

[0009]An object of this invention is to enable a person to use hot water from a tap while preventing cold water replacing the hot water that left the hot water tank.
[0015]Another object of the invention is to have a method and device that protects the hot water tank heating elements from damage when the water level in the hot tank is low. This protection could be by a sensor that detects when the water reaches a given level and an electrical pulse from the sensor to the micro-processor could switch off the heating elements. Alternatively, the hot water tap or the exit hot water pipe could be placed higher than the highest heating element so that the heating elements would remain covered with water.

Problems solved by technology

In addition causing cold water to mix with hot water is not allowed as cooking is not permitted and heating cold water with hot water is considered to be cooking the cold water.

Embodiment Construction

[0018]As will be appreciated the present invention is capable of other and different embodiments than those discussed above and described in more detail below, and its several details are capable of modifications in various aspects, all without departing from the spirit of the invention.

[0019]Accordingly, the drawings and description of the embodiments set forth below are to be regarded as illustrative in nature and not restrictive.

[0020]FIG. 1 shows the internal parts of a standard hot and cooled water dispenser 100. Cold water enters the system via the water purification filters 102. From the filters 102 the water splits into two ways, namely, to the cold water system in piping 104 and to the hot water system in piping 106. The water flowing through pipe 104 is cooled with the aid of a refrigerant, a compressor 109 and an evaporator. The cold water is stored in the cold water tank 108 until a consumer presses the cold water button to make the cold water flow out of the cold water ...

Abstract

Water dispenser with separation between hot and cold water to prevent, temporarily, like on the Sabbath, heating incoming cold water with the hot water in the tank. Ability to temporarily prevent functioning of electronic taps and during such time manual taps would be operable. Ability to temporarily prevent the functioning of the thermostat that controls the water heating elements and during such time to enable the water heating elements to operate at a fixed pre-set temperature.Safety device to prevent the heating elements overheating when water level low.Optional micro-processor to control the apparatus according to the day of the week.

Description

[0001]This invention is in the field of water machines and in particular machines that provide instant hot and cooled water commonly known as “dispensers” or “home bars” making the hot water system isolated from the cold water system to prevent cold water entering the hot water containers when the hot water is used.BACKGROUND OF THE INVENTION[0002]Orthodox Jews are not allowed to heat water on Sabbath. The active use of electricity is forbidden although passive use of electricity is allowed. Therefore, pressing electrically operated buttons and causing the heating elements to operate by a thermostat when removing hot water from a hot water dispenser are actions that are avoided by those who take care not to break the laws of Sabbath. In addition causing cold water to mix with hot water is not allowed as cooking is not permitted and heating cold water with hot water is considered to be cooking the cold water. When a hot water tap is opened in a water dispenser, the volume of hot wate...
