Description
Technical Field
The invention relates to the technical field of water heaters, in particular to a control system of an electric water heater.
Background
At present, people can not keep electric water heaters in production and life, and it is known that the electric water heaters generate a large amount of scale in inner containers for a long time, the scale is very troublesome to clean, the scale pollutes the water quality in the inner containers, hidden dangers are brought to skin health by bathing with the sewage, and a patent with a publication number of (2019208275462) well solves the problem of cleaning the electric water heaters, but the control system is still insufficient.
Disclosure of Invention
In order to overcome the defects of the technical control system of the patent, the technical scheme adopted by the invention for solving the problems is as follows: the utility model provides an electric water heater control system, includes organism, sealed lid, the water heater still includes energy-conserving cover, pressure switch, automatic exhaust valve, relief valve, one-way pressure stabilizing valve, and energy-conserving cover is installed on sealed lid, covers parts such as heating rod, outlet pipe, and pressure switch, automatic exhaust valve are connected respectively on sealed lid lower part outlet pipeline, install one-way pressure stabilizing valve on the inlet pipeline of sealed lid lower part.
The upper part and the lower part of the energy-saving cover are cast with a plurality of convection holes.
The pressure switch may be mounted directly on the sealing cap.
The pressure release valve is fixedly arranged on the steel inner container through a shell, a heat insulation layer and the steel inner container on the machine body.
The invention has the advantages that the energy-saving cover covers the heating rod, the water outlet pipe greatly improves the water outlet temperature of the water heater, the water heater can be washed when being started in summer, the water heater is more energy-saving, the pressure switch controls the power supply to be closed, the water is automatically powered off and the dry burning is prevented, the automatic exhaust valve automatically exhausts the air in the liner during water injection, and the heating rod is prevented from being burnt out when the pressure switch is closed under the condition of water filling.

DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
As shown in figure 1, the electric water heater according to the invention comprises a sealing cover 1, an energy-saving cover 2, a water outlet pipe 3 and a heating rod 4, wherein the energy-saving cover 2 is manufactured into a cylindrical shape, a plurality of convection holes 5 are respectively processed at the upper part and the lower part, the shape of the convection hole 5 is not limited, the energy-saving cover 2 is arranged on the sealing cover 1 and covers the water outlet pipe 3 and the heating rod 4, when the heating rod 4 is electrified to heat and the water outlet pipe discharges water, the water flow forms a small circulation in the energy-saving cover 2 to quickly increase the water outlet temperature, so as to achieve the purpose of washing when the machine is started in summer, when the heating rod 4 is electrified to heat, the water outlet pipe 3 is closed, because the convection cold water flows into the energy-saving cover 2 from the convection hole 5 at the lower part of the energy-saving cover 2 and flows out from the upper part of the energy-saving cover 2 after being heated by the heating rod 4 in a convection way, because the temperature difference of the water in the energy-saving cover 2 is large, therefore, the convection of water is accelerated, a large circulation is formed in the water heater, and the uniform temperature rise of water in the liner is accelerated. As shown in fig. 2, in the patent with reference to publication No. 2019208275462, a pressure release valve 6 is installed on the upper portion of a water heater body a, and when water is injected, air between a silica gel inner container and a steel inner container 9 is automatically discharged, so that the silica gel inner container is tightly attached to the wall of the steel inner container 9, the pressure release valve 6 passes through a shell 7, a heat insulation layer 8 and the steel inner container 9 and is welded and fixed on the outer wall of the steel inner container 9, and two ends of the pressure release valve 6 are flush with the surface of the shell 7 and the inner wall surface of the steel. As shown in figure 3, a water outlet pipeline at the lower part of the sealing cover 1 is respectively connected with a pressure switch 12 and an automatic exhaust valve 11 through a tee joint, the pressure switch 12 controls a power supply, no water pressure is generated, the water heater is not electrified, the effect of preventing the water heater from being dried, the automatic exhaust valve 11 is installed to automatically exhaust air in a liner when the water heater is filled with water, the phenomenon that the water is not full of the pressure switch and the pressure switch 12 is mistakenly operated to cause the drying is prevented, and the pressure switch 12 can also be independently installed outside the. A one-way pressure stabilizing valve (not shown) is arranged on a pipeline at the lower part of the water inlet pipe 13 on the sealing cover 1 to control the pressure of the water heater within a certain range, so that the inner container is protected, and the shower head is smooth and saves water.
