Embodiment 1

[0020] like Figure 1-2 As shown, a self-cleaning type household electric water heater includes a water storage tank 1, the lower end of the water storage tank 1 is fixedly connected with a water outlet pipe 2, and an electric heating tube 3 is arranged directly above the water outlet pipe 2. The side wall is fixedly connected with a mounting seat 4, and the side wall of the mounting seat 4 is rotatably connected with a rotating ring 5, and the rotating ring 5 is coaxially and fixedly sleeved outside the electric heating tube 3, and the inner wall of the outlet pipe 2 is rotatably connected with a fan impeller 6. The upper end of the fan impeller 6 is coaxially fixedly connected with the rotating shaft 7, and the upper end of the rotating shaft 7 is extended to the inside of the water storage tank 1, and the inner bottom surface of the water storage tank 1 is rotatably connected with the crown tooth ring 8, and the outer ring side of the rotating ring 5 The wall is provided wi...

Embodiment 2

[0023] like Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is that two permanent magnet blocks 10 with opposite magnetic poles are fixedly connected to the inner wall of the crown tooth ring 8, and the positions of the two permanent magnet blocks 10 are opposite, and the electric heating tube 3 Outer sliding sleeve is provided with descaling ring 11, and descaling ring 11 is made of magnetic material, and descaling ring 11 repels mutually with one permanent magnet block 10 homopolarity, and attracts with another permanent magnet block 10 heteropolarity.

[0024] In this embodiment, when the crown tooth ring 8 rotates, it drives the two permanent magnet blocks 10 to rotate. Because the two permanent magnet blocks 10 alternately rotate periodically to the head and tail of the electric heating tube 3, under the action of magnetic force, The descaling ring 11 is driven to move back and forth between the head and the tail of the electric heating tube ...

Embodiment 3

[0026] like Figure 5-6 As shown, the difference between this embodiment and Embodiment 1 is that the spoiler rod 9 is covered with a fixed ring 12 and a sliding ring 13, and the fixed ring 12 is located at one end close to the rotating shaft 7 and is fixedly connected with the spoiler rod 9, sliding The ring 13 is located at one end away from the rotating shaft 7 and is slidably connected with the spoiler bar 9. A folding baffle 14 is fixedly installed between the fixed ring 12 and the sliding ring 13. The folding baffle 14 is made of elastic steel sheets, which can be stretched and deformed automatically. reset.

[0027] In this embodiment, the fan impeller 6 drives the spoiler rod 9 to rotate, and the fixed ring 12, the sliding ring 13 and the folding baffle 14 follow the rotation of the spoiler rod 9. The water velocity of the water flow is faster, and the impact force on the fan impeller 6 is larger, so the rotation speed of the fan impeller 6 is faster. Under the action...

Abstract

The invention belongs to the field of household appliances, and particularly relates to a self-descaled household electric water heater. The self-descaled household electric water heater comprises a water storage tank, wherein the lower end of the water storage tank fixedly communicates with a water outlet pipe, and an electric heating pipe is arranged right over the water outlet pipe; a mountingbase is fixedly connected to the side wall of the water storage tank, a rotating ring is rotationally connected to the side wall of the mounting base, and the rotating ring coaxially and fixedly sleeves the electric heating pipe; a fan impeller is rotationally connected to the inner side wall of the water outlet pipe, a rotating shaft is coaxially and fixedly connected to the upper end of the fanimpeller, and the upper end of the rotating shaft is arranged extending into the water storage tank; and a crown gear ring is rotationally connected to the inner bottom surface of the water storage tank, and a tooth groove matched with the crown tooth ring is formed in the side wall of the outer ring of the rotating ring. According to the self-descaled household electric water heater, different side faces of the electric heating pipe are repeatedly opposite to the water flow direction, so that uniform and effective scouring of all positions of the electric heating pipe is achieved, the safetyproblems of short circuit burnout and the like caused by non-uniform heat conduction of all positions of the surface of the electric heating pipe caused by non-uniform scale thickness are avoided, andthe descaling effect is good.

Description

technical field [0001] The invention belongs to the field of household appliances, in particular to a self-cleaning type household electric water heater. Background technique [0002] Water heater is one of the commonly used household appliances in people's life. Electric water heater has beautiful appearance, compact structure, simple pipeline and safe use, and is favored by the public. The heating part of traditional electric water heater is electric heating tube, because the electric heating tube generates heat with high power Parts, when boiling water, the surface is easily oxidized and scaled. Over time, thick scale will be formed on the surface of the electric heating tube, which not only affects the heat exchange efficiency between the electric heating tube and the water body, but also seriously affects the water quality in the water tank. [0003] In the prior art, most electric water heaters install the electric heating tube at the water outlet, and use the outlet w...
