Abstract

The utility model relates to an electric-heating bathtub, which belongs to a novel bathtub. The electric-heating bathtub solves the problem that when the water of the bathtub which does not have the hot water source is heated, the water needs to be heated by using a water heater or other indirect mode. The electric-heating bathtub is composed of the bathtub, a box body, electric heaters, a thermostat, a leakage protector, and a fuse. The electric heaters are fixed around the bathtub, or the electric heaters are fixed on the bottom of the bathtub, or the electric heaters are connected with a heating chamber which is mutually communicated with the bathtub, and the electric heaters are arranged in the heating chamber. The electric heaters are connected with a manual switch, the thermostat, the leakage protector and the fuse through a power supply line, and the bathtub is arranged on in the box body. The electric-heating bathtub has the advantages of convenient movement, quick temperature rise, safety, and convenient repair. The utility model is especially suitable for toilets of families.

Description

The electric heating bathtub

The utility model belongs to a kind of bathtub, exactly is a kind of electrical heating bathtub.

At present, the bathtub of selling does not all have heater on the market, used hot water must have the thermal water source, supplies with bath hot water and all there is hot water pipeline between general resident's domestic hygiene, and the bathtub in like this between domestic hygiene just needs otherwise water is heated put into bathtub again, as water heater etc., but because these mode of heating retainings are slow, the middle sometimes certain interval of time, heat of also needing has certain scattering and disappearing, promptly require great effort and wasted heat, brought certain difficulty for family's bath in a tub.

The purpose of this utility model is invented a kind of easy to use exactly, and is simple to operate, and the electric heating bathtub of water heating in the bathtub is given in safe and reliable direct electricity consumption.

The utility model is achieved in that it is made up of bathtub (9), casing (10), electric heater (5), hand switch (K) temperature controller (DT), buzzer (FM) earth leakage protective device (LB), fuse (RD), it is characterized in that; Bathtub (10) or the fixing heating clamber (6) of electric heater (5) or connection and bathtub (10) mutual conduction in bottom is installed electric heater (5) all around in the heating clamber, electric heater connects with three-terminal polarized plus plug (CT) by power line.Electric heater (5) links to each other with hand switch (K), and hand switch (K) connects temperature controller (DT), and temperature controller (DT) connects earth leakage protective device (LB), and earth leakage protective device (LB) connects fuse (RD) fuse (RD) and is connected with three-terminal polarized plus plug (CT).A buzzer in parallel with temperature controller (FM).Three-terminal polarized plus plug (CT) earthing pole is connected with bathtub (9) shell.Bathtub (9) is installed in the casing (10).

The utlity model has that water can directly heat in the bathtub, quick heating, thermal loss is little, uses conveniently moving, advantage elegant in appearance, owing to have multiple tracks electic protection measures such as earth leakage protective, short-circuit protection and ground protection, uses safe and reliable in addition.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is the overall schematic of the utility model electric heating bathtub.

Fig. 2 is the cutaway view of Fig. 1.

Fig. 3 is the electric of the utility model electric heating bathtub and protection wiring diagram.

1 is the protection terminal box among the figure, and 2 is soft protective case wire, and 3 is metal hose; 4 is the electric heater fixed coupling unit, and 5 is electric heater, and 6 is heating clamber; 7 is the limbers, and 8 is the heating clamber cover plate, and 9 is bathtub; 10 is casing, and CT is a three-terminal polarized plus plug, and RD is a fuse; LB is an earth leakage protective device, and DT is a temperature controller, and FM is a buzzer; K is a hand switch, and DR is an electric heater.Bathtub in the electric heating bathtub (9) and casing (10) adopt sheet metal to be stamped to form through mould, surface enamel, respectively go out a rectangle recess as interior heating clamber (6) at bathtub two walls, electric heater (5) is fixed in the recess, electric heater is fully closed, all the time immerse in the water, heat up gradually, cooling gradually, help prolonging the service life of electric heater, electric heater is installed by the sealed attachment fixture, and electric heater outlet power line and water are isolated, has improved the seal degree and the insulating properties of electric heater.The electric heater power line by seal connector through the metal hose thereto, with electric and the protection wiring diagram on shown in fuse RD, earth leakage protective device LB, temperature controller DT, buzzer FM; By being mounted on shown in the figure on the box inner bottom plating, switch places outside the box.Bathtub (9) inserted in the casing (10) fix, an electric heating bathtub installs.This electric heating bathtub has adopted the measure of multiple tracks electic protection in addition; be connected the protective grounding effect by the three-terminal polarized plus plug earthing pole with the bathtub housing; earth leakage protective device is installed is played the earth leakage protective effect; fuse plays the short-circuit protection effect in the circuit; after water temperature arrived predetermined temperature, the lock outage was chosen in the temperature controller action automatically, and the buzzer prompting bather bathe earlier; at this moment, but the bather pulls up just bathing of plug.More than several measures protection bathers' personal safety.Because this electric heating bathtub can be installed in the special bathtub case, only needing that water pipe is inserted sewer can use, and need not build installation by laying bricks or stones, conveniently moving again promptly attractive in appearance, and easy access, the most suitable resident family uses.
