Description

Hydropower synchronous internal heating overwater automatic electric water heater

The utility model belongs to an electric water heater among household appliances.

The water storage type electric water heaters that are sold in the market and are being used now occupy a large area and need to be heated for a long time before use or kept in a state of heat preservation all the time. There will be a lot of heat energy when heating or heat preservation It is consumed over time, and there is a problem of waiting due to the remaining or insufficient heated water, which not only wastes time but also wastes energy.

The purpose of the utility model is to provide a hydropower synchronous internal heating overwater automatic electric water heater, which can make up for the above-mentioned shortcomings of the existing water heaters.

A hydropower synchronous internal heating overwater type automatic electric water heater, which has a casing, and an electric heating copper inner tube is installed in the casing, and an electric heating wire is installed in the electric heating copper inner tube, and a high temperature resistant insulating porcelain tube is arranged outside the electric heating wire, and the electric heating wire is characterized in that Heating copper inner pipe jacket—copper outer pipe, the space between the electric heating inner pipe and the outer pipe is connected with water inlet pipe and water outlet pipe, the water inlet pipe is connected with—hydraulic actuator, and the hydraulic actuator is connected with a travel switch.

The positive effects and advantages produced by the utility model are as follows:

①All the heat generated by the electric heating wire can be completely absorbed by the water through the internal heat passing water pipe, and converted into hot water to flow out quickly, reducing heat consumption and saving energy.

②When in use, just press the required power selection switch, open the water valve, the power supply will be automatically connected, and hot water will flow out continuously in a few seconds. Save time, there will be no problem of insufficient hot water or remaining hot water, it has advanced functions of water and electricity synchronization, prevention of dry burning, and separation of water and electricity, which is safer and less likely to be damaged.

③Light weight, small footprint, easy operation and installation, and wide application range.

The internal hydraulic transmission system can not only be used in this utility model but its principle can also be applied in other fields. The most important and obvious positive effects are power saving, water saving and time saving, so it benefits the country and the people, and its society , technology, and economic value are very obvious.

Illustrate the utility model below by embodiment and accompanying drawing.

Accompanying drawing 1 is the structure diagram of electric heating tube and control device of the present utility model.

Accompanying drawing 2 is its side view structure diagram.

The utility model has a shell (not shown in the figure), the electric heating copper inner tube (2) is housed in the shell, the electric heating wire (5) is housed in the electric heating copper inner tube (2), and the electric heating wire (5) is equipped with The high-temperature-resistant insulating porcelain tube (4) is equipped with insulating heat-conducting filler quartz sand (6) in the porcelain tube (4). The electric heating inner pipe (2) is equipped with a copper outer pipe (1), and the inner pipe (2) and the outer pipe (1) are connected with the water inlet pipe and the water outlet pipe, and the water inlet pipe is connected with a hydraulic actuator (7), The latter connects travel switch (8), and this switch (8) is connected with the heating wire (5) in 4 electric heating tubes (2) respectively by 4 power selection switches (9). Wherein, the copper outer pipe (1) is a cylindrical hollow pipe in the outer layer that forms the interlayer pipe of the water passage pipe of the electric water heater. The copper inner pipe (2) is a hollow pipe forming the inner cylinder of the interlayer pipe of the water passage pipe of the electric water heater. The copper connecting pipe (3) is a cylindrical hollow pipe that forms the water passing pipe of the electric water heater and plays the role of connecting the passing water. The high-temperature-resistant porcelain tube (4) is a cylindrical hollow tube that is non-conductive and thermally conductive. Quartz sand (6) is a kind of granular fine sand used for insulation, heat conduction and fixing heating wire. The glass syringe type hydraulic transmission (7) has a device body with holes below, and a piston that can slide up and down is arranged in the device body, and it utilizes the pressure of running water to make the piston in the device body transmit by the hole water inlet of the bottom. The upper part of this piston is connected on the travel switch (8). Stroke switch (8) is a kind of switch that can switch current when subjected to the active force of piston. The power selection switch (9) is a switch for manually controlling the on-off of the current. The earth leakage protector (10) is an electrical appliance capable of automatically cutting off power when there is an electric leakage. Indicator lamp (11) is a kind of luminescent tube that shows current on-off. The neutral wire in the outgoing line of the leakage protector (10) is connected to one end of all heating wires (5), the live wire is connected to the incoming line of the travel switch (8), and the outgoing line of the travel switch (8) is connected to each power selection switch (9) The incoming line connection of each power selection switch (9) is respectively connected to the other end of a heating wire (5), and then the two wires of the indicator light (11) are respectively connected to the outgoing line of the travel switch (8). Connect with the zero line of the outlet of the leakage protector (10), so that the glass syringe type hydraulic actuator (7) can make the travel switch (8) control the on or off of the current only when there is a certain water pressure or no water pressure, so as to realize the hydropower Synchronous internal heating overwater automatic electric water heater.
