Abstract

The utility model relates to a bathtub. The middle of the bottom surface of a bathtub body is provided with a groove, a heating plate is installed in the groove, the inside of the heating plate is provided with a ring-shaped electric heating core, a protection plate is positioned on the heating plate and is provided with a through hole, and the electric heating core is connected with a power supply by a selective switch and a thermostat. When the utility model is used, the water temperature of the bathtub can be controlled arbitrarily, the safe use and the convenient operation can be realized, a user can take a bath no matter whether the hot water is provided or not, and the function of the temperature protection can be realized.

Description

Electrothermic insulation bathtub

The utility model relates to a kind of bathtub.

At present the bathtub that generally uses of people does not all have heating and heat insulation function, need boil water to pour bathtub into and carry out bathing, if water-cooled, also need constantly to add hot water, use more loaded down with trivial details, also not very convenient, and can't soak for a long time,, then have to hope cylinder heave a sigh if do not have hot water or boiling water.

The purpose of this utility model is exactly in order to address the above problem, and a kind of electrical heat tracing bathtub is provided.

Structure of the present utility model as shown in the figure.

Fig. 1 is a profile schematic diagram of the present utility model.

Fig. 2 is the vertical view (only provide half among the figure, second half is symmetry fully) of Fig. 1;

Fig. 3 is the utility model electrical heating cut-away section schematic diagram;

Fig. 4 is the utility model electrical heating part electrical schematic diagram.

Such as Fig. 1,2,3,4, the utility model has circular groove at the middle part, bottom surface of bathtub body 1, and metal heating disc 2 is housed in it, and its edge is fixedly connected with the step of bathtub body 1 circular groove one circle, be added with one deck sealing asbestos washer 3 therebetween, infiltrate to prevent the water in the bathtub. Be provided with an annular heating core 4 in the metal heating disc 2, heating core 4 adopts the heating core that uses in the electric cooker base, heating wire one termination power in the heating core 4, one end of another termination bimetal thermostat 5, the b shelves of K switch are selected in simultaneously selecting, and the movable contact of selector switch K connects power supply, and the c end of K switch is selected in the other end selecting of bimetal thermostat 5, thermostat 5 is installed on the bottom surface of heating plate 2, adds Activity is placed with a protective plate 6 on the upper surface of heat dish 2, some through holes are arranged on its surface, so that flowing into by these through holes, the water in the bathtub carries out heat cycles on the heating plate 2, protective plate 6 is preferably arc surfaced, its adopt metal material or nonmetallic materials all can, as long as intensity can sustain human body weight.

When the utility model uses, if when meeting no hot water, can let cool water in bathtub body 1, selector switch K is beaten the shelves at b, make heating core 4 energising heating, electric hot tray 2 namely produces heat energy, and the cold water in the bathtub body 1 flow into by the through hole on the protective plate 6 and carries out heat exchange on the heating plate 2, and constantly circulation, make the water in the bathtub become hot water, when water temperature is suitable, selector switch K is dialled the shelves at c, connect thermostat 5 this moment, when if water temperature is higher than design temperature, thermostat 5 automatic cut-off powers, stopped heating, on the contrary heat with regard to automatic plugged. If hot water is arranged, then can directly selector switch K be beaten the shelves at c, carry out thermostatic control, save electric energy. The utility model for safety inserts earth leakage protector 7 and fuse 8 in electric heater unit, earthing or grounding means is also arranged on the electric hot tray 2, in case electric leakage, circuit is protection automatically.

The utility model is simple in structure, and is easy to use, can control the water temperature in the bathtub arbitrarily, safe and reliable, no matter have or not hot water, but all bathings, and have heat insulation function, like the long-time user who soaks for some and brought Gospel.

Claims

1, a kind of electrical heat tracing bathtub, it is characterized in that having circular groove at the middle part, bottom surface of bathtub body 1, METAL HEATING PROCESS dish 2 is housed in it, fixedly connected with the step of bathtub body 1 circular groove one circle in its edge, be added with one deck sealing asbestos washer 3 therebetween, to prevent that the water in the bathtub from infiltrating, be provided with an annular heating core 4 in the METAL HEATING PROCESS dish 2, heating wire one termination power in the heating core 4, one end of another termination bimetal thermostat 5, the b shelves of K switch are selected in selecting simultaneously, and the movable contact of selector switch K connects power supply, and the c shelves of K switch are selected in the other end selecting of bimetal thermostat 5, thermostat 5 is installed on the bottom surface of heating plate 2, activity is placed with a protective plate 6 on the upper surface of heating plate 2, and some through holes are arranged on its surface, and the water in the bathtub just flow into by these through holes and carries out heat cycles on the heating plate 2.
