Description
Technical Field
The invention relates to the field of water heaters, in particular to a quick-heating water storage type electric water heater.
Background
The electric water heater is a water heater which takes electricity as energy source for heating, and is one of three water heaters which are parallel to a gas water heater and a solar water heater. The electric water heater can be divided into a water storage type, an instant heating type and an instant heating type according to the heating power, wherein the main household form is the water storage type. The existing water storage type electric water heater is generally composed of a shell, a heat preservation liner, a heating pipe, a water inlet pipe, a water outlet pipe, a control circuit and the like, the water stored in the heat preservation liner is heated to the required temperature by the heating pipe, and the water storage type electric water heater can be used conveniently. However, the existing water storage type electric water heater needs to consume a lot of heating time when the stored water is heated to a certain temperature. When the temperature is reduced, the temperature of the stored water can be reduced only by mixing the inlet water and the stored water in the electric water heater, and the temperature of the outlet water is mainly regulated by an external water mixing valve, so that the cold water and the hot water are mixed, and the temperature of the water is reduced. However, the water mixing valve does not adjust the water storage temperature of the electric water heater, and the water temperature is often adjusted by the water mixing valve, which easily causes continuous heating of the heating pipe of the electric water heater, resulting in unnecessary loss and energy consumption. For this reason, improvements to the existing electric water heater are needed.
Disclosure of Invention
In order to overcome the defects, the invention designs the quick-heating water storage type electric water heater, so that the technical problems that the existing water storage type electric water heater is difficult to quickly heat water and the energy consumption is increased due to a single temperature adjusting mode are solved. The technical scheme is adopted for realizing the method.
The quick-heating water storage type electric water heater comprises a shell, a heat-preserving cylinder, a heating pipe, a control circuit, a water inlet pipe and a water outlet pipe, wherein the heat-preserving cylinder is positioned in the shell, the water inlet pipe and the water outlet pipe are respectively connected into an inner cavity of the heat-preserving cylinder from the outside of the shell, the heating pipe is installed at one end of the inner cavity of the heat-preserving cylinder, and the heating pipe is connected with the control circuit. The water inlet pipe enters the inner cavity of the heat-insulating cylinder and is branched into two paths, one path is directly communicated with the bottom of the inner cavity of the heat-insulating cylinder, the other path is communicated with one end of the spiral heat-conducting pipe, and the spiral part of the spiral heat-conducting pipe is sleeved outside the heating pipe and is not contacted with the heating pipe; the water outlet pipe enters the inner cavity of the heat-preserving cylinder and is branched into two paths, one path is communicated with the inner cavity of the heat-preserving cylinder, and the other path is communicated with the other end of the spiral heat-conducting pipe; the water inlet pipe and the water outlet pipe are respectively provided with an electromagnetic valve for controlling the switching conduction of respective branch pipelines, and when the electromagnetic valve of the water inlet pipe controls the conduction of the water inlet pipe and the spiral heat conduction pipe, the electromagnetic valve of the water outlet pipe controls the conduction of the water outlet pipe and the spiral heat conduction pipe; when the electromagnetic valve of the water inlet pipe controls the water inlet pipe to be communicated with the inner cavity of the heat-insulating cylinder, the electromagnetic valve of the water outlet pipe controls the water outlet pipe to be communicated with the inner cavity of the heat-insulating cylinder.
According to the structure, the spiral heat conduction pipe is arranged adjacent to the heating pipe, so that when the electric water heater is not heated to a specified temperature, water flows in and out of the spiral heat conduction pipe are firstly heated quickly by the heating pipe, and the quick heating and water outlet of the electric water heater are realized; when the stored water in the inner cavity of the heat-insulating cylinder is heated to the required temperature, the electromagnetic valve controls the conduction of the water inlet pipe and the water outlet pipe with the inner cavity of the heat-insulating cylinder, thereby keeping the water supply at the specific temperature. When the temperature is reduced, the heating pipe stops heating, water flows in the spiral heat conduction pipe and the water storage in the heat preservation cylinder exchange heat by utilizing water inlet and water outlet of the spiral heat conduction pipe, so that the water temperature in the spiral heat conduction pipe is increased, the water storage temperature in the heat preservation cylinder is reduced, and the purpose of quickly reducing the water temperature is achieved. Besides, the spiral heat conduction pipe enables the change of the temperature of the stored water in the inner cavity of the heat preservation cylinder to be linear, and the temperature sensor and the heating pipe of the electric water heater work more reliably and stably, thereby being beneficial to energy conservation and reducing energy consumption.
When the electromagnetic valve is powered off, the water inlet pipe and the water outlet pipe are communicated with the inner cavity of the heat-insulating cylinder, so that the electric water heater can still normally supply water when the power is off.
One end of the spiral heat conduction pipe, which is connected with the water outlet pipe, is provided with a conjoined water storage tank, and the wall surface of the water storage tank is an elastic corrugated surface. Through setting up elasticity ripple face, make the water storage tank have the water pressure that changes because of the temperature risees in the self-adaptation spiral heat pipe.
The water storage tank conducts heat between the inner cavity of the water storage tank and the inner cavity of the heat-preserving cylinder. The water storage tank is designed to conduct heat, so that heat exchange is carried out between the inner cavity of the water storage tank and the inner cavity of the heat-insulating cylinder, and the heat exchange efficiency is improved.
And heat conducting fins are uniformly distributed on the outer wall of the water storage tank. Further improving the heat exchange efficiency between the inner cavity of the water storage tank and the inner cavity of the heat preservation cylinder.
