Ultrasonic wave scale-deposit-preventing electric heater
Technical field
The utility model relates to a kind of water heater that improves structure, specifically belongs to a kind of ultrasonic wave scale-deposit-preventing electric heater.
Background technology
The electric heater of existing market use, owing to water quality inferiority, hardness height, after use a period of time, the component surfaces such as heating tube and temperature-sensing pipe all can generate the thick incrustation scale of one deck, the problem of energy waste and easy booster can occur.When safeguarding, need the professional that electric heater is taken apart, change whole heating tube, safeguard inconvenience, cost is high.
For this situation, ultrasonic wave electric water heater has appearred, " a kind of ultrasonic water heater " disclosed such as China Patent No. ZL200520128549.5, it comprises ultrasonic generator switch, transformer, ultrasonic signal generator and the transduction piece that is connecting from water heater power supply, its major defect is that the ultrasonic wave transducer sheet is positioned within the Water outlet spray head, outside dirt can only be removed, the fouling of electric heater inside can't be prevented.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of easy and simple to handle, ultrasonic wave scale-deposit-preventing electric heater that can effectively prevent the water heater internal incrustation is provided.
The technical scheme that realizes the utility model purpose is: a kind of ultrasonic wave scale-deposit-preventing electric heater, comprise shell, inner bag, heating tube, control panel, ultrasonic generator and connecting line, wherein said ultrasonic generator is electrically connected with control panel by connecting line; An end that it is characterized in that described ultrasonic generator inserts in the inner bag and with inner bag and is threaded, and the other end of ultrasonic generator places in the space between shell and the inner bag.
Described ultrasonic generator comprises ultrasonic rod, transducer and sealing ring, and wherein said ultrasonic rod and transducer connect into integral body, is provided with groove at ultrasonic rod near an end of transducer, and described sealing ring is installed in the groove.
Described ultrasonic rod is pole or polygon rod, and is processed with screw thread.
Be provided with binding post at described transducer, described binding post is electrically connected with an end of connecting line, and the other end of connecting line is connected with the control panel electricity.
Be provided with opening at described inner bag, opening part is provided with the screw thread that matches with ultrasonic rod, and described ultrasonic rod inserts in the inner bag and with opening part from opening part and is threaded, and transducer places in the space between shell and the inner bag.
The utility model advantage compared with prior art is: disturb and destroy the formation of incrustation scale by ultrasonic wave; can regular, timing automatic parts in the inner container of electric water heater be cleaned; remove incrustation scale and surface contaminants; avoid the deposit corrosion inner bag; the important spare parts such as protection heating tube need not to adopt specific purpose tool to tear machine open and clean, can effectively reduce maintenance cost; have the advantages such as easy to use, minimizing energy waste.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, a kind of ultrasonic wave scale-deposit-preventing electric heater comprises shell 1, inner bag 2, heating tube 3, control panel 4, ultrasonic generator 5 and connecting line 6, and wherein said ultrasonic generator 5 is electrically connected with control panel 4 by connecting line 6; The utility model characteristics are that an end of described ultrasonic generator 5 inserts in the inner bag and with inner bag 1 and is threaded, and the other end of ultrasonic generator 5 places in the space between shell 1 and the inner bag 2.
In the present embodiment, described ultrasonic generator 5 comprises ultrasonic excellent 52, transducer 51 and sealing ring 53, wherein said ultrasonic excellent 52 connect into integral body with transducer 51, are provided with groove 521 ultrasonic excellent 52 near ends of transducers 51, and described sealing ring 53 is installed in the groove.
Described ultrasonic excellent 52 is pole or polygon rod, and is processed with screw thread.In the present embodiment, ultrasonic excellent 52 is pole, also can arrange as required ultrasonic excellent 52 shape.
In the present embodiment, be provided with binding post 7 at described transducer 51, described binding post 7 is electrically connected with an end of connecting line 6, and the other end of connecting line 6 is connected with control panel 4 electricity.
In the present embodiment, be provided with opening at described inner bag 2, opening part is provided with and ultrasonic excellent 52 screw threads that match, and described ultrasonic excellent 52 insert in the inner bag 2 and with opening part from opening part and to be threaded, and transducer 51 places in the space between shell 1 and the inner bag 2.
During work; the parameters such as the ultrasonic wave working hour that controller 4 is set according to the user and temperature; signal is passed to transducer 51; transducer 51 instructs ultrasonic excellent 52 to start working; produce ultrasonic wave, make the WATER AS FLOW MEDIUM in the inner bag 2 produce cavitation effect, the dirt, the incrustation scale that are attached to inner bag 2 inner components surfaces are removed; avoid the deposit corrosion inner bag, the important spare parts such as protection heating tube.
