Water dispenser with a cleaning mechanism

A water dispenser apparatus, comprising:

• a water supplying unit for containing water to be dispensed to a user of the water dispenser apparatus;
• a cold water tank for receiving water from the water supplying unit;
• a hot water tank for receiving water from the water supplying unit;
• a suction unit for pumping water from the water supplying unit towards the cold water tank and the hot water tank;
• a water outlet for dispensing water from the water dispenser apparatus, said water outlet is connected to the hot water tank and to the cold water tank;
• a control unit from which the suction unit receives a command to perform suction;
• a cold unit valve connected to the control unit for controlling water flow from the suction unit to the cold water tank;
• a hot unit valve connected to the control unit for controlling water flow from the suction unit to the hot water tank;
• a supply valve connected to the water supplying unit for controlling water flow from the water supplying unit towards the water outlet;
• a first cold suction tube connected to the cold water tank, to a suction valve and to the suction unit and a second cold suction tube connected to the cold unit valve and to the cold water tank;
• wherein the suction unit is configured to suck water from the suction tubes;
• wherein the water sucked by the suction unit from the first and second cold suction tubes is used to clean tubes and tanks at the water dispenser apparatus and is transferred through tubes of the water dispenser apparatus;
• wherein the control unit is configured to control the valves and the suction unit for activation of two cleaning cycles of the water dispenser apparatus, wherein a primary cleaning cycle includes cleaning a first portion of the tubes and the cold water tank of the water dispenser apparatus, and a secondary cleaning cycle includes cleaning a second portion of the tubes of the water dispenser apparatus;
• and
• wherein the secondary cleaning cycle includes cleaning the second cold suction tube, and the control unit is further configured to set the cold unit valve to an open state, the hot unit valve to a closed state and the suction valve to an open state.
