Wherein, the water heater shell includes: the foamed heat-insulating layer 3 is arranged on the shell, and the decorative panel is arranged on the shell; the decorative panel comprises a plastic piece 1 and a glass panel 2, wherein the plastic piece 1 is fixed on the mounting opening, the plastic piece 1 is provided with a pasting opening, the glass panel 2 comprises a display area 21 and a non-display area 22, and the non-display area 22 is mounted in the pasting opening; the foaming heat preservation layer 3 is positioned in the shell, and the non-display area is adhered and fixed in the adhering opening by the foaming heat preservation layer 3 at the adhering opening. The structure, function and effect of the water heater shell are the same as those of the above embodiments, and the above embodiments can be specifically referred to, and are not described herein again.
Further, the utility model provides a water heater still includes inner bag, heating element, and wherein, the inner bag setting is inside the water heater shell, and heating element sets up in the inner bag the inside.
The heating element may be an internal tubular structure, the metal sleeve is often stainless steel or steel tubing, or the heating element may be a ceramic heater. The heating principle of the electric water heater is that after the water heater is electrified, the heating element is electrified to generate heat, so that the water stored in the inner container is heated to raise the temperature, after the temperature reaches a set temperature, the temperature controller cuts off the power supply to stop heating, and the water in the inner container is in a heat preservation state due to the heat insulation effect of the foaming heat preservation layer; when the heating is stopped for a long time and the water temperature of the water in the inner container is lower than the set lower temperature limit, the temperature controller is closed, the heating element starts to work again, and the heating-heat preservation-heating working state is maintained in such a circulating way.
In addition, the magnesium rod is used as an anode protection device and is specially used for protecting the inner container and the heating tube, the activity of magnesium ions of the magnesium rod is higher than that of a steel plate when the electric water heater is in a power-on state, calcium carbonate in water firstly makes a sound reaction with the magnesium ions to form magnesium oxide, and thus iron and calcium carbonate can be placed to react to form iron oxide, so that water leakage of the inner container is caused. Therefore, the magnesium rod becomes a vulnerable product for replacing corrosion, and a user can select the replacement time according to water to prevent the corrosion of the inner container and the heating tube.
Generally, the core components of an electric water heater further include a temperature controller and a temperature limiter, wherein the switch of the temperature controller is in a closed state at normal temperature; when the temperature rises, a special medium (such as aviation kerosene) in the metal capillary tube thermally expands, the root of the metal capillary tube is communicated with the metal diaphragm, and when the temperature exceeds the upper limit temperature, the metal diaphragm deforms, so that the switch is switched off. After the switch is disconnected and the reset temperature is reduced, the deformation rate of the metal diaphragm is reduced, and the switch is closed. That is to say, the temperature controller is used for preventing the temperature of the water in the inner bag from exceeding the set constant temperature, and the temperature controller can play a role in tripping to stop heating, thereby playing a first layer of overheat protection.
Furthermore, the principle of the temperature limiter is the same as that of the temperature controller, but the set overheating temperature of the temperature limiter is greater than the set constant temperature of the temperature controller, and when the water temperature exceeds the set overheating temperature, the temperature limiter can cut off the live wire and the zero wire of the power supply, so that the second-layer overheating protection is realized.
Furthermore, the water heater also comprises a water inlet pipe and a water outlet pipe which are respectively connected with the inner container, wherein the water inlet pipe is generally short, and the water outlet pipe is generally long, because the specific gravity of hot water floats on the upper surface, and the specific gravity of cold water sinks on the lower surface. In order to avoid the heat efficiency loss generated by the hot and cold water circulation exchange, the double-liner electric water heater is applied, namely an upper liner and a lower liner are arranged in a shell.
Of course, the water heater provided by the utility model also comprises an electricity-proof device, a safety valve and the like, and is not limited herein.
The utility model provides a water heater, it includes the water heater shell to the water heater shell includes: the thermal insulation board comprises a shell, a foaming thermal insulation layer and a decoration panel, wherein the shell is provided with an installation opening; the decoration panel comprises a plastic part and a glass panel, the glass panel comprises a display area and a non-display area, the plastic part is fixed on the mounting opening, a pasting opening corresponding to the non-display area is formed in the plastic part, the glass panel at the pasting opening is directly bonded with the foaming heat insulation layer, and therefore the glass panel is fixed on the plastic part, a connecting structure does not need to be additionally arranged, the assembly process is simple, the efficiency is high, and the cost is reduced. And, set up the opening of pasting on the working of plastics, alleviateed the weight of working of plastics, correspondingly, reduced the weight of water heater, be favorable to the installation and the fixed of water heater.
So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, a person skilled in the art can make equivalent changes or substitutions to the related technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
