Description

Technical Field

[0001] The utility model relates to the technical field of water boilers, in particular to a water boiler with a built-in descaling device. Background Art

[0002] At present, water machines are widely used in various scenes of people's lives. The cleanliness of the water source and the amount of minerals it contains not only directly affect people's health, but also affect the service life of water machine equipment such as heating tubes, water machine tanks, faucets, and water pipe interfaces. The formation of scale usually starts with the formation of tiny crystals, which precipitate from the supersaturated solution to form layers of scale.

[0003] The descaling device in the prior art has the following disadvantages: after the water is heated, the calcium sulfate (CaSO4) slightly soluble in water in the water is precipitated due to the evaporation of water, and the originally dissolved calcium bicarbonate (Ca(HCO3)2) and magnesium bicarbonate (Mg(HCO3)2) are decomposed in the boiling water, releasing carbon dioxide (CO2), and the insoluble calcium carbonate (CaCO3) and magnesium hydroxide (Mg(OH)2) are also precipitated, and sometimes MgCO3 is also generated, thus forming scale. The scale inhibitor is in the scale growth. In the budding stage, that is, the initial stage of scale crystal nucleus formation, it participates in and interferes with the formation process of scale crystal nucleus in the form of ions, causing the crystal nucleus to be distorted and forcing it to die in the development stage, so that scale is no longer possible. The harm of scale is that it is easy to accumulate calcification under high temperature and repeated boiling. The accumulation of calcification leads to shortened mechanical life, reduced thermal efficiency, and is not conducive to human health. Later, people added water purification and filtration devices to the water boiler. The disadvantage is that it increases production costs, is inconvenient to install, and the accumulation of calcifications has not improved. Utility Model Content

This not only avoids the additional installation cost of the water purification filter device, but also ensures the efficiency and quality of the descaling operation. Descaling is performed regularly to ensure the quality and efficiency of descaling.

[0023] like Figure 1-Figure 3 As shown, two through grooves are provided on the water boiler housing 14, and the water inlet pipe 8 and the sewage discharge pipe 12 pass through the interior of the two through grooves respectively.

[0024] like Figure 1-Figure 3 As shown, two circular grooves are provided on the water mixing quick-connect tee 10, and one end of the connecting pipe 9 and the water inlet pipe 8 are respectively fixedly connected to the inner walls of the circular grooves.

[0025] The specific implementation principle of this embodiment is as follows: the user can add descaling agent to the storage tank 5 in advance and store it therein, and time the water inlet solenoid valve 2, the quick-connect normally closed solenoid valve 7 and the switch valve. The quick-connect normally closed solenoid valve 7 is opened, and the descaling agent flows into the descaling agent delivery pipe 6, flows into the connecting pipe 9 through the quick-connect normally closed solenoid valve 7, and finally flows into the mixing water quick-connect tee 10.

The descaling agent and tap water are mixed in the mixing water quick-connect tee 10, and then enter the water boiler inner tank 13. The electronic control program will control the water boiler inner tank 13 to heat and descale. After the heating and descaling are completed, the user opens the drain valve 4 to discharge the sewage and complete the descaling work.

[0026] Example 2

[0027] like Figure 1-Figure 5As shown, this embodiment also introduces a water boiler with a built-in descaling device, which adds the following structure on the basis of the first embodiment: a support plate 16 is welded on the inner wall of the water mixing quick-connect tee 10, and a mixing shaft 20 is rotatably installed on the bottom of the support plate 16 and the inner wall of the water mixing quick-connect tee 10, and a rotating shaft 17 is rotatably installed on the inner wall of the water mixing quick-connect tee 10, and a rotating drum 18 is fixedly sleeved on the outer circumference of the rotating shaft 17, and a plurality of circumferentially evenly distributed fan blades 19 are welded on the outer circumference of the rotating drum 18, and a plurality of mixing blades 21 are welded on the outer circumference of the mixing shaft 20, and a driving shaft 22 is rotatably installed inside the support plate 16, and the driving shaft 22 A synchronous belt 15 is installed together with the outer circumferential surface of the rotating shaft 17, a protective shell 1 is arranged on one side of the water machine housing 14, and an anti-misopening lock 3 is arranged together with the protective shell 1 and one side of the water machine housing 14.

[0028] like Figure 4-Figure 5 As shown, synchronous wheels are fixedly sleeved on the outer circumferences of the rotating shaft 17 and the driving shaft 22, and the synchronous belts 15 are installed together on the outer circumferences of the two synchronous wheels.

[0030] The specific implementation principle of this embodiment is as follows: when tap water flows into the mixing water quick-connect tee 10, the circulation of tap water drives the fan blades 19 to rotate, and then drives the rotating shaft 17 to rotate through the rotating drum 18. The rotating shaft 17 realizes the rotation of the driving shaft 22 through the synchronous belt 15. The rotation of the mixing shaft 20 is realized due to the meshing of the driving bevel gear 24 and the driven bevel gear 23. The mixing shaft 20 drives the mixing blades 21 to rotate, so that the mixing blades 21 stir the tap water and the descaling agent to fully blend the two and ensure the descaling quality.
