Utility Model Implementation

In view of the foregoing, it is necessary to refer to embodiments of the proposed utility model, one or more examples of which are shown in the drawings. The embodiments are illustrated by the proposed utility model and are not intended to limit the proposed utility model. For example, features shown or described as part of one embodiment may be used in another embodiment to create an additional embodiment. The proposed utility model provides for the inclusion of these and other modifications and changes within the scope and essence of the proposed utility model.

1 and 2 illustrate an electric heating device 100 for boiling water in accordance with the first embodiment of the proposed utility model. An electric heating apparatus 100 for boiling water comprises a reservoir 101 for containing water to be heated; a heater 111 for heating water in the tank 101 by means of electricity. The electric heating device 100 for boiling water further comprises a unit for bringing into operation an inhibitor that prevents the formation of scale, which can automatically cause water to enter the unit for bringing into operation an inhibitor that prevents the formation of scale when water is poured into reservoir 101, with the aim of forming an inhibitor solution, preventing the formation of scale. In addition, the descaling inhibitor reduction unit may release a formed scale inhibitor inhibitor solution into the reservoir 101 in order to prevent scale formation during boiling of water. The configuration and operation of the descaling inhibitor inhibitor will be described in detail below in conjunction with several exemplary embodiments.

As shown in figures 1 and 2, in some embodiments, the implementation of the tank 101 has a handle 102 attached to its outer side surface. The tank 101 has an upper opening 1011 through which users can pour water into the tank 101. The tank 101 also has a water hole 106 so that water in the tank 101 can be poured out of the tank 101. The handle 102 is usually located in the opposite direction to the radial direction of the tank 101 to the hole 106 for water. Thus, users can hold the handle 102 to tilt the tank 101 towards the water hole 106 so that water can be poured out of the tank 101 through the water hole 106.

In some embodiments, the handle 102 of the electric heating apparatus 100 for boiling water has a chamber 103 adjacent to the reservoir 101 as part of the descaling inhibitor block. The interior of the chamber 103 and the reservoir 101 may be divided by the side wall of the reservoir 101. Thus, the side wall of the reservoir 101 can serve as the same wall of the chamber 103. In some embodiments, the upper part of the chamber 103 has a water inlet 1031 formed on the side the wall of the tank 101, which is in communication with the tank 101, the lower part of the chamber 103 has an outlet 1032 for water formed on the side wall of the tank 101, which is in communication with the tank 101. In that In this embodiment, a scale inhibitor 110 is loaded into the chamber 103 between the water inlet 1031 and the water outlet 1032. A scale inhibitor 110 is suitable for dissolution in water to form a scale inhibitor inhibitor solution in order to prevent scale formation and growth when the solution is heated. The scale inhibitor 110 may be any substance suitable for the prevention of scale that is currently known or will be created, for example, phosphoric acid phosphate, etc.

In some embodiments, the electric heating apparatus 100 for boiling water may further comprise a drainage channel 104 configured to fit in the upper opening 1011 of the tank 101. In some embodiments, the drainage channel 104 may be detachable so as to facilitate cleaning of the interior of the tank 101. Of course , the drainage channel 104 may still be attached to the reservoir 101. In some embodiments, the implementation of the drainage channel 104 may be shaped in the form of a diaphragm, covering the upper opening 1011. The diaphragm has openings 1041 divided into compartments, spaced in a number of shapes, to allow most of the water supplied through the upper opening 1011 to pass through the holes 1041 to flow into the heating tank 101.

In particular, as shown, the diaphragm still has a gutter 1042. The gutter 1042 extends to the water inlet 1031 and leans toward the water inlet 1031. With this design and arrangement, when users pour water into the tank 101 through the diaphragm, part of the water can flow into the gutter 1042 and can flow towards the water inlet 1031 through the gutter under the influence of weight. In one embodiment, the diaphragm acting as a catchment channel 104 may also be gradually depressed towards the center. Thus, it is more certain that the water supplied to the diaphragm is partially discharged into the gutter 1042, which extends through the center of the diaphragm along the surface of the diaphragm, which is depressed towards the center.

In some embodiments, the inner wall of the reservoir 101 has a first water inlet edge 105 below the gutter 1042. The first water inlet edge 105 is also located below one end of the gutter 1042 near the water inlet 1031, and partially overlaps with the gutter 1042 in the radial direction of the tank 101. In such an embodiment, the water receiving edge 105 may receive water flowing from the end of the gutter 1042 and direct it to the water inlet 1031.

When users pour water into the reservoir 101 through the upper opening 1011, most of the water flows directly into the reservoir 101 through the openings 1041 of the drainage channel 104, and a smaller amount of water passes through the gutter 1042 of the drainage channel 104 and the first intake edge 105, and goes into the chamber 103 from the inlet 1031 for water. The water entering the chamber 103 comes into contact with a scale inhibitor 110 placed therein in order to partially dissolve the chemical mass of the scale inhibitor 110 in water to form a solution of the scale inhibitor 110.

The formed scale inhibitor inhibitor solution can flow into the tank 101 through the water outlet 1032 below the chamber 103, and can be mixed with water directly poured into the tank 101 to form water containing a scale inhibitor to be heated. Thus, by means of the drainage channel 104, the first water intake edge 105, and the chamber 103 filled with the scale inhibitor, the descaling inhibitor inhibitor can automatically cause water to enter the descaler inhibitor , for the formation of a solution of the inhibitor that prevents the formation of scale, while water is supplied to the tank 101, and the supply of the formed solution, preventing it is scaled into the tank 101. When the water in the tank 101 is heated by the heater after the water has been infused, the scale inhibitor dissolved in the water will prevent the formation and accumulation of scale.

In one embodiment, the water opening 106 may also have a second water receiving edge 107. In this embodiment, the other end of the gutter 1042 also extends to the second water receiving edge 107. Thus, when water is supplied to the tank 101 through the water opening 106, part the water supplied to the tank 101, can pass the second water receiving edge 107 and flow through the gutter 1042 and then enter the chamber 103 to form a solution of the inhibitor that prevents the formation of scale, and flow into the cut rvuar 101.

In one embodiment, the electric heating device 100 for boiling water further comprises a lid 109 and a unit for putting the scale inhibitor into operation, further comprises an exhaust valve 108 located in the water outlet 1032. The exhaust valve 108 is configured to actuate the lid 109 to open the exhaust valve 108 to release a scale inhibitor inhibitor solution from the chamber 103 to the reservoir 101 while the lid 109 is located on the upper opening 1011 of the reservoir 101. Thus, until once the lid 109 is located on the upper hole 1011, the water entering the chamber 103 may come into contact with the scale inhibitor 110 therein for a long period of time and until it leaves l chamber 103. Water in the chamber 103 leaves the chamber 103 and passes into the tank 101 only until the lid 109 is located. This is advantageous since a larger amount of scale inhibitor 110 dissolves in contact with water, thereby increasing the effect of the scale inhibitor. Of course, this configuration may not be needed.

In some embodiments, the concentration of the scale inhibitor inhibitor solution can be controlled by adjusting the volume of the chamber 103 and the amount of scale inhibitor 110 for water in the chamber 103. Alternatively and additionally, the contact time of the water and the scale inhibitor is and the flow rate of the solution can be controlled by adjusting the diameter of the openings of the water outlet 1032 and / or the outlet valve 108 s in zmozhnostyu achieving concentration adjustment target solution. By selecting a suitable configuration of the above parameters, a scale inhibitor inhibitor solution with the same substantially suitable concentration can be automatically obtained in the tank 101 when water is each time supplied to the tank 101 in order to achieve a better prevention effect. scale formation.

In the above embodiments, the scale inhibitor can be stored in the handle 102 and not immersed in hot water all this time. Moreover, the scale inhibitor is also far from the heat source. Thus, the quality of the inhibitor that prevents the formation of scale is not affected by heat and steam, therefore, the electric heating device for boiling water can maintain a stable quality during its full service life.

Figure 3 shows another example implementation of an electric heating device 100 for boiling water in accordance with the proposed utility model. In this embodiment, the descaling inhibitor reduction unit is no longer implemented by parts such as the handle 102 and the chamber 103. Specifically, in this embodiment, the descaling inhibitor reduction unit contains a funnel 201, located on the upper hole 1011 of the tank 101. FIG. 4 shows an example of the configuration of the funnel 210. As shown, the funnel 210 may have a catchment portion 2011, a water outlet 2014 and a containment portion 2013 located between the catchment portion 2011 and the water outlet 2014. The catchment part 2011 has openings 2012 for the penetration of water, spaced in a number of forms. When water is supplied from the upper opening 1011, most of the water can be supplied directly to the tank 101 through the water penetration openings 2012. The drainage portion 2011 may have a tapered surface in an inverted position in order to partially divert water supplied from the upper opening 1011 to the containment portion 2013 below the catchment portion 2011. An inhibitor 210 is prevented to form scale in the containment portion 2013. The water discharged from the catchment part 2011 and directed to the containing part 2013 and the scale inhibitor, in the containing part 2013 comes into contact with the possibility of forming a scale inhibitor inhibitor solution. Then, as shown in FIG. 5, the scale inhibitor inhibitor solution flows into the reservoir 101 through the water outlet 2014 below the enclosing portion 2013.

In some embodiments, a water outlet 2014 may be provided with a control valve. The concentration and transmission rate of the solution can be adjusted by adjusting the diameter of the control valve. Thus, each time the infusion of water can completely automatically bring the scale inhibitor solution to an operational state with a suitable concentration in order to achieve the expected effect of preventing scale formation.

In one embodiment, the drainage portion 2011 of the funnel 201 may partially extend into the water hole 106 (see FIG. 3). When water is supplied to the tank 101 through the water hole 106, a portion of the supplied water will be directed to the funnel 201 along the drainage portion 2011, continuing to the water hole 106, and form a solution of an inhibitor that prevents the formation of scale, and flow into the tank 101.

6-7 depict another example implementation of an electric heating device 100 for boiling water in accordance with the proposed utility model. The difference between this embodiment and the embodiments mentioned above lies in the design and configuration of the descaling inhibitor block. Specifically, in this embodiment, the descaling inhibitor inhibitor unit comprises an inhibitor holder 301 located in the reservoir 101. The inhibitor holder 301 may be located close to the bottom of the reservoir 101, or may be located at some distance from the bottom. In these circumstances, in which the heater 111 is the bottom surface of the inner cavity of the tank 101, the inhibitor holder 301 may be located close to the heater 111. In one embodiment, the inhibitor holder 301 is ring-shaped to avoid over-coating the heater 111 in the bottom reservoir 101 and effects on the heating effect.

A scale inhibitor 310 is loaded into the inhibitor holder 301 to form a scale inhibitor inhibitor solution. The inhibitor holder 301 has an upper hole 302 and a lower hole 303. Since the inhibitor holder 301 is located directly in the tank 101 when water enters the tank 101, the entire inhibitor holder 301 will be directly absorbed by the water in the tank 101. As indicated above, the inhibitor holder 301 can stand from the bottom of the tank 101. Thus, the water in the tank 101 can easily enter the lower hole 303 of the holder 301 of the inhibitor. And water in the tank 101 can also easily flow into the upper hole 302 of the inhibitor holder 301. Thus, water in the reservoir 101 can circulate between the inner space and the outer space of the inhibitor holder 301 through the lower hole 303 and the upper hole 302 so that water entering the inner space of the inhibitor holder 301 can come into contact with the inhibitor 310 that prevents formation scale, and form an inhibitor solution that prevents the formation of scale. The scale inhibitor solution may then flow from the inhibitor holder 301 to the tank 101. Convection of water in the tank 101 after heating will aid the water to be circulated inside and outside the inhibitor holder 301 in order to promote the scale inhibitor 310 dissolve in water in tank 310.

Since the anti-scale inhibitor 310 is in the inhibitor holder 301 and is in contact with water only through the small upper holes 3012 and the lower holes 303, the contact time of the water and the anti-scale inhibitor 310 can be controlled by the size and number of the upper holes 302 and lower holes 303, and, in turn, regulate the concentration of the formed inhibitor solution that prevents the formation of scale.

The descaling inhibitor reduction unit, in the above embodiments, can automatically direct water to the descaling inhibitor reduction unit to form a solution of the anti-scale inhibitor when water is supplied to the electric heating apparatus 100 for boiling water . The formed scale inhibitor inhibitor solution can then be automatically fed into the water in the reservoir 101 to prevent scale formation and growth when the water is heated. Thus, users not only really regularly do not need to manually descale, but also get rid of the boring steps of adding an inhibitor to the water to prevent scale formation. In addition, since the anti-scale inhibitor activation unit automatically discharges the anti-scale inhibitor solution, each time water is supplied, all boiling water each time has a function to prevent the formation of scale in use in order to prevent formation and accumulation of scale. Thus, the electric heating device for boiling water can be kept clean for a long time and have good performance. In this case, since users do not need to use citric acid or vinegar to remove scale, the electric heating device for boiling water will not produce a specific smell and will affect the taste of water after descaling. It should be understood that the constant transmittance of the scale inhibitor inhibitor solution during each use provided by the scaling inhibitor inhibitor unit ensures that scale formation is effectively prevented during each use of the electric water boiling device.

It should be noted that the above embodiments provide principles for illustrating the proposed utility model, rather than limiting its scope. It should be understood that it is easy for a person skilled in the art to understand that modification and alteration can be made without departing from the spirit and scope of the present utility model. Such modifications and changes are recognized to be within the scope of this utility model and the appended claims. The scope of legal protection of this utility model is determined by the attached formula. In addition, the reference position in the claims should not be construed as limiting to the claims. The use of the word “comprises” and its variant does not exclude elements or steps other than those listed in the claims. The indefinite article ʺaʺ or ʺanʺ before an element or step does not exclude the presence of many such elements.
