Embodiment 1

[0027] refer to figure 1 and Figure 9 , a bare wire electric water heater heater, including a heating body, an electric heating wire 4 and a power supply controller 7, the heating body includes a main body 1, an upper cover 3 and a lower cover 2, the lower cover 2 is provided with several lower connecting grooves 21, and the upper cover 3 A plurality of upper connecting grooves 31 are provided, the lower cover 2 is provided with a water inlet 22 and is connected to a water inlet joint 220, the upper cover 3 is provided with a water outlet 32 ​​and is connected to a water outlet joint 320, and the main body 1 is provided with a number of parallel water channels. The upper cover 3 and the lower cover 2 connect the water passages in the main body 1 in series through the upper connecting groove 31 and the lower connecting groove 21 respectively to form a water inlet and electricity protection wall 11, an electric heating chamber 12 and an outlet water and electricity protect...

Embodiment 2

[0042] refer to figure 2 , the difference between this embodiment and Embodiment 1 is that the water flow switch channel 14 is set on the water inlet and electricity protection wall 11, that is, one of the water channels of the water inlet and electricity protection wall 11 is used as the water flow switch channel 14, and the water flow switch channel 14 has a built-in magnetic levitation Sub 5, the outer side of the main body 1 near the water flow switch channel 14 is provided with a magnetic contact switch 6, and the water outlet electric wall 13 has no water flow switch channel.

[0043] Its working principle is the same as that of Embodiment 1.

[0044] The heating body of this embodiment can also adopt such as Figure 9 structure, will Figure 9 Water inlet 22 and water outlet 32 ​​in the interchange just passable, be about to make water inlet 22 water inlet, water outlet 32 ​​is made water inlet.

Embodiment 3

[0046] refer to image 3 , the difference between this embodiment and embodiment one is:

[0047] The upper cover 3 is also provided with a middle water outlet hole 33 connected to the middle water outlet joint 330 , and the middle water outlet hole 33 communicates with one of the water passages of the water inlet and electric protection wall 11 . This further enables the output of hot or cold water at different temperatures:

[0048] During installation, use the water inlet pipe to connect the water inlet joint 220 to the tap water source, connect the plug of the power supply controller 7 to the power supply, and connect the water outlet joint 320 and the middle water outlet joint 330 to the 2-in and 1-out mixing water regulating valve (Fig. 2 water inlets (not shown), and the water outlet of the mixing regulating valve is connected to the water outlet pipe.

[0049] The working principle is:

[0050] When cold water is to be used, the mixed water regulating valve is adjus...

Abstract

The invention relates to the technical field of electric water heaters and provides a heater of a bare-wire electric water heater. The heater of the bare-wire electric water heater comprises a heating unit, a heating wire and a power supply controller. The upper cover and the lower cover of the heating unit connect a water channel inside the heating unit body in series through a connecting groove to form a water inlet electricity guard wall, an electric heating chamber and a water outlet electricity guard wall; the heating wire is arranged inside the electric heating chamber; the heating unit is provided with a water inlet and a water outlet; the water channel inside the heating unit body serves as a water switch channel, and the inside of the heating unit body is provided with a magnetic floater; a magnetic contract switch is arranged outside the heating unit, and the probe of a temperature control switch extends into the water outlet electricity guard wall; and the heating wire, the temperature control switch and the magnetic contact switch are respectively connected with the power supply controller. The heater of the bare-wire electric water heater has the advantages that a water switch and the heating unit is combined together, so that the structure is compact and the installation is convenient; due to the design of the heating unit with a middle water inlet hole or a middle water outlet hole, the water outlet temperature can be adjusted more conveniently; and a reversing valve and the heating unit are of an integral structure, so that the structure is more compact and the installation is more convenient.

Description

technical field [0001] The invention relates to the technical field of electric hot water heating, in particular to fast electric water heaters, dual-mode electric water heaters, instant electric water faucets, under-the-table treasures and the like using nickel-gold bare wire heating technology. Background technique [0002] In recent years, nickel-gold bare wire heating technology has been applied in fast electric water heaters. Its advantages are: the heating wire is directly placed in the water for heating, and the heat generated by the heating wire is immediately taken away by the water. There is no interval conduction and radiation, so the thermal efficiency Higher; the surface temperature of the heating wire is lower when heating, and it will not scale. Since the heating wire is directly placed in the water, the water is directly conductive. Therefore, people design the anti-electric wall to make the heater meet the safe use standard. It was released on January 5, 201...
