Multiple-temperature continuously water supplying power saving electrically heating drinking water machine

Abstract

The power saving electrically heating drinking water machine consists of casing, boiled water draining tap, warm water draining tap, heat exchanger, right and left heating tanks, right and left safe overflow valves, upper right and left normally opened cut-off valves, lower right and left normally opened cut-off valves, right and left normally closed cut-off valves, right and left temperature controllers, right and left electric heaters and limited water inlet pipe. It can heat water electrically without pressure, limit water discharge before boiling, provide boiling water continuously and provide warm drinking water, and has saving in electric power and other advantages.

Description

technical field [0001] The invention relates to a water dispenser, in particular to a novel non-voltage electric heating continuous water supply multi-temperature energy-saving water dispenser, which belongs to the technical field of daily electrical appliance manufacturing. Background technique [0002] At present, the drinking water heating device supplied by tap water on the market can only realize the water discharge by the pressure of the tap water due to the high position of the tap water, so that the heating of the water is also carried out under pressure. The heating tank of this heating method is a pressurized container. , not only the cost is high, but also very unsafe; according to the measurement, when heating, the water pressure in the tank is changed from 0.2-0.3 MPa (2-3 kg / cm) of the tap water pipeline. 2 ) The pressure suddenly rises above 1-2 MPa, for this reason a safety relief valve must be installed and set at about 0.7 MPa, so that when the water in the...

Problems solved by technology

[0002] At present, the drinking water heating device supplied by tap water on the market can only realize the water discharge by the pressure of the tap water due to the high position of the tap water, so that the heating of the water is also carried out under pressure. The heating tank of this heating method is a pressurized container. , not only the cost is high, but also very unsafe; according to the measurement, when heating, the water pressure in the tank is changed from 0.2-0.3 MPa (2-3 kg / cm) of the tap water pipeline. 2 ) The pressure suddenly rises above 1-2 MPa, for this reason a safety relief valve must be installed and set at about 0.7 MPa, so that when the water in the heating tank is heated and expands during heating, the water pressure exceeds 0.7 MPa , it will be discharged through the safety overflow valve to prevent the pressure in the heating tank from continuing to rise. Even so, this heating method is still a pressure vessel, which still needs to withstand a pressure of about 0.7 MPa, and once the safety overflow valve fails, There are still hidden dangers! In addition, because the drinking water heating device for the above-mentioned tap water supply also has the phenomenon of mixed water supply of cold and hot water, the defect that the water can be released without boiling the water

The present inventor invented a piezoelectric heating water dispenser to solve the above-mentioned defects. It does not change the structure of the original water dispenser device, and only adds a few conventional and general-purpose devices to realize the piezoelectric heating function and the water cannot be released if the water is not turned on. It solves the defect of mixed cold and hot water supply of water, but there are defects of continuous water supply, direct drinking of warm water and no energy saving
