In the using process, when water is added into the inner container 11, the pressure cover 2, the water feeding pipe 3 and the filter cup 4 can be taken out of the inner container 11 so as to conveniently add water; when heating, the pressure cover 2, the water feeding pipe 3 and the filter cup 4 are put into the inner cavity of the kettle body 1 (namely the inner cavity of the inner container 11) so as to filter water in the inner cavity of the kettle body 1; after heating, the pressure cover 2, the water feeding pipe 3 and the filter cup 4 can be taken out from the inner container 11, so that water can be poured conveniently.
The pressure cover 2 is provided with a cover opening and a cover bottom, when the pressure cover 2 is placed in the inner container 11, the cover opening faces the inner container 11 and covers the inner bottom surface of the inner container 11, and the cover bottom is opposite to the cover opening. A gap is arranged between the pressure cover 2 and the inner bottom surface of the inner container 11, so that water in the inner container 11 can enter the pressure cover 2 from the outside of the pressure cover 2.
The filter cup 4 is provided with a cup opening and a cup bottom, the cup opening is upward, and the cup bottom is opposite to the cover bottom of the pressure cover 2. When the filter cup 4 is placed in the inner container 11, the filter cup 4 is positioned at the top of the inner container; moreover, the bottom of the filter cup 4 does not exceed the highest water level line of the inner container 11, so that the water outside the filter cup 4 is prevented from exceeding the bottom of the filter cup 4 to influence the filtering effect.
In addition, when the filter cup 4 is put into the inner container 11, the position can be fixed by the pressure cover 2; the cup mouth of the filter cup 4 can also be provided with an outward bent folded edge, the inner wall of the inner container 11 is provided with a step, so that the filter cup 4 is fixed by erecting the folded edge on the step of the inner container 11, wherein the height of the step from the inner bottom surface of the inner container 11 is consistent with the height between the folded edge of the filter cup 4 and the cover mouth of the pressure cover 2.
The water feeding pipe 3 is vertically arranged, one end of the water feeding pipe is communicated with the bottom of the pressure cover 2, and the other end of the water feeding pipe is communicated with the filter cup 4, so that water in the pressure cover 2 can flow into the filter cup 4 through the water feeding pipe 3. When the upper water pipe 3 is communicated with the filter cup 4, the upper water pipe can be specifically communicated with the cup bottom of the filter cup 4 and also can be communicated with the cup wall of the filter cup 4; in a preferred embodiment, the water supply pipe 3 is communicated with the bottom of the filter cup 4 in this embodiment, so as to reduce the length of the water supply pipe 3 and save materials.
The water feeding pipe 3, the pressure cover 2 and the filter cup 4 can be of a split structure or an integrated structure. Wherein, split type structure is convenient for the intake of water-feeding pipe 3, pressure housing 2 and filter cup 4, and the water-feeding pipe 3, pressure housing 2 and the connection leakproofness of filtering cup 4 of integral type structure are good, are difficult for the pressure release. In the specific setting, the selection can be arbitrary according to the requirement.
When the water feeding pipe 3, the pressure cover 2 and the filter cup 4 are of a split structure, the water feeding pipe 3, the pressure cover 2 and the filter cup 4 can be connected together in a threaded manner. During concrete implementation, can correspond on the cover bottom of pressure cap 2 and the cup bottom of crossing filter cup 4 and set up the screw, set up the external screw thread respectively at the both ends of water pipe 3, water pipe 3 through the external screw thread at both ends respectively with pressure cap 2 and the screw spiro union on crossing filter cup 4, realize dismantling the connection. When the user does not use the water feeding pipe 3, the pressure cover 2 and the filter cup 4 to filter the water scale, the water feeding pipe 3, the pressure cover 2 and the filter cup 4 can be taken out of the inner container 11 and then detached to be stored, so that the storage space occupied by the water feeding pipe 3, the pressure cover 2 and the filter cup 4 is reduced.
When the water feeding pipe 3, the pressure cover 2 and the filter cup 4 are of an integrated structure, the water feeding pipe 3, the pressure cover 2 and the filter cup 4 can be connected together in a welding mode.
In this embodiment, the working principle of the electric kettle for filtering the scale specifically is as follows: when the electric kettle is heated, the heating device 13 transfers heat to the water in the inner container 11 through the inner container 11, so that the temperature of the water in the inner container 11 is increased; in the heating process, along with the boiling of water in the inner container 11, the volume of the water in the pressure cover 2 expands, the density becomes smaller and lighter, and bubbles are generated to rise, so that a small pressure space is formed in the pressure cover 2; under the action of pressure, water in the pressure cover 2 rises through a water feeding pipe 3 communicated with the cover bottom of the pressure cover 2 and then flows into a filter cup 4, and water in the filter cup 4 downwards flows into an inner container 11 after water scale is filtered by the filter cup 4; the water around the pressure cover 2 is supplemented into the pressure cover 2 to form circulation, and the water in the whole inner container 11 is filtered through continuous circulation.
After water in the electric kettle is filtered by the filter cup 4 in the heating process, scale is not easily formed at the bottom of the inner container 11, so that a user does not need to clean the electric kettle frequently; moreover, after the filter cup 4 is used for a period of time, the user can take out the filter cup 4 for cleaning, so that the filter cup is convenient to clean; in addition, after the scale in the electric kettle is filtered, a user can drink more healthily.
When the water in the pressure cover 2 rises through the water feeding pipe 3 under the action of the pressure in the pressure cover 2, the higher the pressure in the pressure cover 2 is, the higher the rising height of the water in the pressure cover 2 in the water feeding pipe 3 is, and the faster the flow rate is; the faster the flow rate in the water feed pipe 3 is, the greater the amount of filtered water, that is, the greater the number of times the water in the inner container 11 is filtered, and the better the filtering effect, for the same filtering time.
In order to make the pressure in the pressure hood 2 sufficiently large so that the water in the pressure hood 2 can rise quickly into the filter cup 4, the area of the hood opening of the pressure hood 2 is larger than the area of the hood bottom in the present embodiment. Namely, the pressure cover 2 is of a structure with a big lower part and a small upper part; under the condition that the heat received at the cover opening is the same, the smaller the volume of the pressure cover 2 is, the larger the internal pressure is, and the faster the rising speed of the water in the pressure cover 2 is; therefore, in this embodiment, the structure of the pressure housing 2 with a large bottom and a small top can reduce the volume of the pressure housing 2, increase the pressure in the pressure housing 2, and accelerate the rising speed of the water in the pressure housing 2.
In a specific implementation, the longitudinal section of the pressure cover 2 may be trapezoidal, V-shaped, or U-shaped as shown in fig. 1, and may be selected as needed in a specific design, which is not particularly limited in this embodiment. Fig. 1 is merely an exemplary illustration of a trapezoid.
In addition, the cross-section of the pressure shell 2 may be circular, square or of another shape, preferably circular. Under the condition of the same diameter, the circular area is the largest, the cross section of the pressure cover 2 is circular, the area of the cover opening of the pressure cover 2 can be increased, the heat received in the pressure cover 2 is improved, the pressure in the pressure cover 2 is further improved, and the rising speed of water in the pressure cover 2 is accelerated; moreover, the beauty can be improved, and the cleaning by users is convenient.
The more heat in the pressure housing 2, the more pressure is generated inside; in the heating process of the electric kettle, the temperature above the heat generating source (i.e. the heating device 13) is the highest, and in order to make the pressure cover 2 have enough heat to generate enough pressure, in the embodiment, the pressure cover 2 needs to contain most or all of the heat generating source; preferably, the pressure cover 2 includes all the heat generating sources, i.e., the heating device 13 is located in the area covered by the pressure cover 2, so as to increase the heat in the pressure cover 2 and further increase the pressure generated inside the pressure cover 2.
When the size of the opening of the pressure cover 2 is set, the heating device 13 may be included, and when the opening is too large, the other portion of the inner container 11 that does not contact the heating device 13 may be included, and the temperature of this portion is relatively low, so that the volume of the pressure cover 2 is increased, the heat per unit volume is decreased, and the pressure in the pressure cover 2 is affected.
The maximum inner diameter of the opening of the pressure cover 2 is smaller than the inner diameter of the top opening of the inner container 11, so that the pressure cover 2 can be taken out of the inner container 11.
In addition, the pressure in the pressure cover 2 is also affected by the gap between the pressure cover 2 and the inner container 11, the smaller the gap, the less heat is dissipated outwards from the pressure cover 2, and the greater the pressure in the pressure cover 2, so that in a specific implementation, a suitable gap can be set, for example, less than a preset gap threshold value, to ensure the pressure in the pressure cover 2.
In specific implementation, the edge of the pressure cover 2 may be covered on the inner bottom surface of the inner container 11 by a downward convex foot, and the gap between the pressure cover 2 and the inner container 11 may be set by setting the height of the convex foot. The edge of the pressure cover 2 can also be wavy, and the gap between the pressure cover 2 and the inner container 11 can be set by setting the distance between the peak valley and the peak top of the wavy edge.
In addition, the higher the power of the heating device 13 is, the more heat is in the pressure cover 2, the higher the pressure generated inside the pressure cover is, and in the specific implementation, the heating power of the heating device 13 is not suitable to be too small, for example, the heating power of the heating device 13 may be set to be greater than a preset power threshold value, so as to avoid that the filtering of the scale is affected due to insufficient pressure in the pressure cover 2.
In order to further improve the convenience of the user in using the electric kettle, in the embodiment, the inner surface of the filter cup 4 may be covered with the filter screen 5. Can filter the incrustation scale that boils water in-process formation through filter screen 5 like this, after using a period, can take out filter screen 5, change a new filter screen 5 to improve the filter effect, thereby the user need not to wash filter cup 4, and it is more convenient to use.
In specific implementation, the filter cup 4 can be provided with a larger filter hole so as to facilitate the water in the cup to flow out. The filter cup 4 can be provided with filter holes only at the bottom, correspondingly, the filter screen 5 can only cover the bottom of the filter cup 4, and the arrangement mode has lower cost; the filter cup 4 can also be provided with filter holes on the cup bottom and the cup wall at the same time, correspondingly, the filter screen 5 covers the cup bottom and the cup wall of the filter cup 4 at the same time, and the arrangement mode has better filter effect and higher speed. In this embodiment, preferably, a manner that the filter cup 4 is provided with filter holes on the cup bottom and the cup wall at the same time and the filter screen 5 covers the cup bottom and the cup wall of the filter cup 4 at the same time is adopted to improve the filtering effect, and fig. 1 is an exemplary illustration of such an arrangement.
The filter screen 5 can be made of gauze, an active carbon layer or a nylon net; in order to improve the filtering effect, the filtering net 5 may be provided in multiple layers.
In order to improve the filtering effect, in this embodiment, the top end of the upper water pipe 3 may extend into the inner cavity of the filter cup 4.
Specifically, if the water supply pipe 3 is flush with the bottom of the filter cup 4, when filtering, water in the water supply pipe 3 flows into the filter cup 4 and then flows back to the pressure cover 2 from the water supply pipe 3 easily, so that the filtering effect is influenced.
