Piston-type electric water heater with variable-volume inner container

Abstract

The invention discloses a piston-type electric water heater with a variable-volume inner container. A duplex piston is mounted in the inner container of a water tank of the electric water heater, and divides the inner container of the water tank into two cavities. One cavity is for holding cold water, and the other cavity is for holding hot water, so that the cold water and the hot water can be separated. When water enters the cold water cavity, the piston is pushed to discharge the hot water. Cold-water inlet or hot-water outlet are controlled by two two-position three-way electromagnetic valves positioned in the cavities respectively. The electromagnetic valves are interlocked, and when cold water enters one cavity, and hot water comes out from the other cavity. The length of the inner container of the water tank of the electric water heater is divided into ten equally, eleven reed pipe magnetism-sensitive special switches are mounted at the ten equant positions on the outer wall of the inner container of the water tank, and eleven volume indicators are mounted on a panel of the electric water heater and displayed as numbers of one to eleven. When the piston enters one equant position, the corresponding volume indicator is turned on by the corresponding reed pipe magnetism-sensitive special switch, vice versa, lighting of one volume indicator means that the piston is located at the position.

Description

technical field [0001] The present invention is a new type of energy-saving and safe electric water heater. It installs a double-connected piston in the water tank liner of the water heater, enters the cold water to push the piston, and the piston pushes the hot water to discharge, which completely subverts the existing mixing of cold water and hot water. water way. Background technique [0002] Electric water heater is a kind of household appliance that family generally uses, and it is very popular among users because of its convenience. But this water heater has its own defective: the one, part heat energy is wasted in vain when storing for a long time; 4. The volume of the water tank liner is fixed, and the volume cannot be adjusted as required. These defects are inherent in this kind of electric water heater, and this is because there are deficiencies in the working principle of this kind of electric water heater: one is to enter cold water to get out hot water, and th...

But this water heater has its own defective: the one, part heat energy is wasted in vain when storing for a long time; ; Fourth, the volume of the inner tank of the water tank is fixed, and the volume cannot be adjusted according to the needs

These defects are inherent in this kind of electric water heater, and this is because there are deficiencies in the working principle of this kind of electric water heater: one is to enter cold water to get out hot water, and the mixing of cold water and hot water makes the water temperature lower, and in order to maintain the water temperature heater It must work continuously, which increases the consumption of electric energy; the second is that the electric water heater is in working condition when taking a bath, and once the circuit is abnormal, it will cause an electric shock accident; The water temperature drops a lot in the second day, and the heat energy is wasted in vain; Fourth, the volume of the inner tank of the electric water heater is fixed, and the volume cannot be adjusted as needed.
