Further, the water heater provided by the utility model further comprises an inner tank and a heating element, wherein the inner tank is arranged inside the water heater shell, and the heating element is arranged inside the inner tank.

The heating element can be an inserted tubular structure, the metal sleeve is usually stainless steel or steel pipe, and the heating element can also be a ceramic heater. The heating principle of the electric water heater is that after the water heater is energized, the heating element is energized to generate heat, so that the water stored in the inner tank is heated and heated. After reaching the set temperature, the thermostat cuts off the power supply and stops heating. The water in the inner tank is due to foaming. The thermal insulation effect of the thermal insulation layer is in the thermal insulation state; when the heating is stopped for a long time, and the water temperature of the water in the inner tank is lower than the lower limit of the set temperature, the thermostat is closed, and the heating element starts to work again, so that the cycle is maintained in heating-insulation-heating working status.

In addition, the magnesium rod is used as an anode protection device, which is specially used to protect the inner tank and the heating pipe. The magnesium rod is the activity of magnesium ions in the electric water heater is higher than that of the steel plate. The calcium carbonate in the water first reacts with the magnesium ions to form magnesium oxide. , so that the iron can be placed to react with calcium carbonate to form iron oxide, causing the inner tank to leak. It can be understood from this that the magnesium rod has become a consumable product that replaces corrosion, and the user can choose the replacement time according to the water to prevent the corrosion of the inner tank and the heating tube.

Usually, the core components of the electric water heater also include a thermostat and a temperature limiter, wherein, when the thermostat is in a normal temperature state, its switch is in a closed state; when the temperature rises, the special medium (for example, aviation kerosene) in its metal capillary tube Thermal expansion, and the root of the metal capillary is connected to the metal diaphragm. When the temperature exceeds the upper limit temperature, the metal diaphragm is deformed and the switch is disconnected. After disconnection, when it is lowered to the reset temperature, the deformation rate of the metal diaphragm is reduced, so that the switch is closed. That is to say, the thermostat is used to prevent the water temperature in the inner tank from exceeding the set constant temperature, and the thermostat will trip, stop heating, and play the first layer of overheat protection.

Further, the principle of the temperature limiter is the same as that of the thermostat, but the set overheating temperature of the temperature limiter is greater than the set constant temperature temperature of the thermostat. When the water temperature exceeds the set overheat temperature, the temperature limiter will cut off the power supply. The live wire and the neutral wire play a second layer of overheating protection.

Further, the water heater also includes a water inlet pipe and a water outlet pipe, which are respectively connected with the inner tank. Generally, the water inlet pipe is short and the water outlet pipe is long, because the specific gravity of hot water floats above, and the specific gravity of cold water sinks below. In order to avoid the loss of thermal efficiency caused by the circulation exchange of cold and hot water, the double-tank electric water heater is applied, that is, two inner tanks, an upper tank and a lower tank, are arranged in the shell.

Of course, the water heater provided by the present invention also includes an anti-electricity device, a safety valve, etc., which are not limited herein.

The water heater provided by the utility model comprises a water heater casing, and the water heater casing comprises: a casing, a foamed thermal insulation layer and a decorative panel, wherein the casing is provided with an installation opening; the decorative panel includes a plastic part and a glass panel, and the glass panel Including a display area and a non-display area, the plastic part is fixed on the installation opening, and the plastic part is provided with a sticking opening corresponding to the non-display area, and the glass panel at the sticking opening is directly bonded to the foam insulation layer, so that the The glass panel is fixed on the plastic part, no additional connection structure is required, the assembly process is simple, the efficiency is high, and the cost is reduced. In addition, a sticking opening is provided on the plastic part, which reduces the weight of the plastic part, correspondingly reduces the weight of the water heater, and is beneficial to the installation and fixation of the water heater.
