Detailed Description

The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
In one aspect of the invention, a container is provided. According to an embodiment of the invention, with reference to fig. 1, the container comprises: a container body 100, a magnetostrictive member 200, and an alternating magnetic field member 300. Wherein the magnetostrictive member 200 is disposed on the container body 100, and the magnetostrictive member 200 is made of a magnetostrictive material, and the alternating magnetic field member 300 is used to provide an alternating magnetic field to the magnetostrictive member 200. Therefore, the container can relieve or solve the problem of early switch jump caused by scale, and has high quality.
For ease of understanding, the operating principle of the container according to an embodiment of the invention is first briefly explained below:
as described above, although electric kettles and health-preserving kettles are popular with consumers, scale is generated during long-term use of the electric kettles and the health-preserving kettles, and the scale is difficult to clean. According to the embodiment of the invention, the magnetostrictive component and the alternating magnetic field component are arranged on the container, the alternating magnetic field is generated by the alternating magnetic field component, the magnetostrictive component can vibrate under the action of the alternating magnetic field, and further, in the using process of the container, the adhesion force of impurity ions on the bottom and the side wall of the container can be reduced by utilizing the vibration of the magnetostrictive component, so that the formation of scale is slowed down. Or after the container is used for a long time to generate scale, the vibration of the magnetostrictive component can separate the scale from the bottom and the side wall of the container, and further the scale is removed. Therefore, the phenomenon of early switch jumping can be avoided, and the container can be normally used.
The following detailed description of the various parts of the container is given according to a specific embodiment of the invention:
the shape of the container body and the material of construction are not particularly limited, and those skilled in the art can design them as the case may be.
According to an embodiment of the present invention, magnetostrictive member 200 is constructed of a magnetostrictive material. The particular type of magnetostrictive material that makes up the magnetostrictive member is not particularly limited and can be selected by one skilled in the art on a case-by-case basis. Specifically, the magnetostrictive material mainly comprises three types, the first type is traditional nickel-based alloy, iron-based alloy and ferrite, and the magnetostrictive coefficient of the material is low and is only 20-80 ppm; the second is PZT piezoelectric ceramic, the magnetostriction coefficient of the material is 200-400ppm larger than that of the first material; the third one is a rare earth intermetallic compound magnetostrictive material which is (Tb, Dy) Fe2The alloy with the compound as the matrix, namely the Tb-Dy-Fe material, has a magnetostriction coefficient which is much larger than that of the traditional material and can reach 1500-2000 ppm. Thus, the third magnetostrictive material has significant advantages: the magnetostriction coefficient of the composite material is 50 times larger than that of the first material and 5-25 times larger than that of the second material. As will be appreciated by those skilled in the art, the magnetostriction coefficient is characterized by the ratio of the elongation of a material along the magnetization direction to the total length of the material under the influence of a magnetic field. That is, the greater the magnetostriction coefficient, the greater the elongation of the material under the influence of the magnetic field. Thus, among the three materials, the rare earth intermetallic compound magnetostrictive material has the largest elongation in a magnetic field. In addition, the third magnetostrictive material has the following advantages: the thrust generated by it is very large, for example, the thrust generated by a bar with a diameter of 10mm is about 200 kg; the energy conversion efficiency is high and can reach 70%, while the metal nickel is only 16%, and the PZT material is 40-60%; the response time is very short and is only one millionth of a second; the elastic modulus of the magnetic field-adjustable magnetic field is adjustable. For the third materialThe property of the material in a magnetic field is that the length of the rare earth intermetallic compound magnetostrictive material can change under the action of the magnetic field, and then the material is displaced to do work, or the material is repeatedly stretched under the action of an alternating magnetic field, so that vibration is generated. According to an embodiment of the present invention, magnetostrictive member 200 may be constructed of a rare earth intermetallic magnetostrictive material. Therefore, the descaling can be carried out by utilizing the characteristic that the magnetostrictive material of the rare earth intermetallic compound generates vibration by repeated expansion in the alternating magnetic field, and the problem of early jump of the container switch caused by scale can be relieved or solved.
The working principle of the container according to an embodiment of the invention is explained with reference to fig. 3:
after the container is energized, alternating current is supplied to alternating magnetic field unit 300 (e.g., high frequency induction heating coil) to generate high frequency alternating magnetic field H1, and when magnetic lines of force in the magnetic field pass through the bottom of the container, eddy current 10 is generated to generate induced magnetic field H2, that is, alternating magnetic field is generated by supplying alternating current to alternating magnetic field unit 300. The magnetostrictive member 200 is frequently elongated and shortened by the alternating magnetic field, and vibration is generated as the magnetostrictive member 200 is elongated and shortened. Therefore, the alternating magnetic field is generated by the alternating magnetic field component in the using process of the container, so that the magnetostrictive component generates vibration, the adhesive force of the scale to the container is weakened, and the scale removing effect is further achieved. According to the embodiment of the present invention, the vibration caused by magnetostriction does not cause mechanical fatigue like vibration of a vibrating plate, and it is not necessary to provide a vibration space. Therefore, the magnetostrictive component is adopted to generate better vibration effect and longer service life.
The position of the magnetostrictive member is not particularly limited as long as it can generate vibration under the action of the alternating magnetic field, and those skilled in the art can design it as the case may be. For example, according to an embodiment of the present invention, the magnetostrictive member 200 may be disposed on the sidewall of the container body 100, whereby scale on the sidewall of the container may be removed. Alternatively, according to other embodiments of the present invention, the magnetostrictive member 200 may be disposed at the bottom of the container body 100 (as shown in fig. 1), whereby scale on the bottom of the container may be removed. In addition, the magnetostrictive component 200 is arranged at the bottom of the container body 100, and because the vibration is performed from bottom to top and the inner wall of the container is symmetrical, the side wall of the container can be vibrated, and then the scale on the side wall of the container can be removed, so that a better descaling effect can be obtained. Thus, according to an embodiment of the present invention, it is preferable to provide the magnetostrictive member 200 at the bottom of the container body 100.
The number of magnetostrictive members is also not particularly limited, and those skilled in the art can design them as the case may be. For example, according to an embodiment of the present invention, the magnetostrictive member 200 may be one, whereby scale in the container can be removed. In order to improve the ability to remove scale, according to other embodiments of the present invention, a plurality of magnetostrictive members 200 may be further provided on the container body 100. Also, in order to further improve the ability to remove scale, according to an embodiment of the present invention, referring to fig. 2, a plurality of magnetostrictive members 200 may be symmetrically disposed at the bottom of the container body 100. This can further reduce the adhesion of scale to the container, and improve the descaling efficiency.
The mounting manner of the magnetostrictive member is not particularly limited, and those skilled in the art can design it as the case may be. For example, according to an embodiment of the present invention, the magnetostrictive member 200 may be mounted on the container body 100 by at least one of welding, adhesion, and mechanical assembly. Thus, the mounting of the magnetostrictive member can be completed with a simple process.
The shape of the magnetostrictive member is also not particularly limited, and those skilled in the art can design it as the case may be. For example, according to an embodiment of the present invention, the shape of the magnetostrictive member 200 may include at least one of a square shape and a circular shape. Thereby, the magnetostrictive member can be matched with the container body.
The specific type of the alternating magnetic field component is not particularly limited as long as the alternating magnetic field can be generated, and those skilled in the art can design the component according to the specific situation. For example, according to an embodiment of the present invention, the alternating magnetic field part 300 may be a high-frequency induction heating coil, and thus, an alternating magnetic field may be generated by passing an alternating current through the high-frequency induction heating coil.
The positional relationship between the alternating magnetic field member and the magnetostrictive member is not particularly limited as long as the magnetostrictive member is within the range of the alternating magnetic field generated by the alternating magnetic field member, and those skilled in the art can design the magnetostrictive member according to the circumstances. For example, according to an embodiment of the present invention, magnetostrictive member 200 may be disposed at the bottom of container body 100, and alternating magnetic field member 300 may be disposed at a side of magnetostrictive member 200 away from container body 100.
According to an embodiment of the present invention, the container may further include a heating member. The specific type of the heating member is not particularly limited, and those skilled in the art can design it according to the specific situation. For example, according to an embodiment of the present invention, the heating member may include at least one of a resistive heating member and an electromagnetic heating member. In particular, when the heating element is a resistive heating element, heating may be achieved by generating thermal energy by the joule effect of current flowing through the conductor. According to an embodiment of the present invention, the resistance heating part may be a heating pipe, an electric heating plate, or the like. When the heating component is an electromagnetic heating component, an alternating magnetic field can be generated by the electromagnetic heating component, so that the surface of the container placed on the heating component cuts alternating magnetic lines, and alternating current (namely eddy current) is generated at the metal part at the bottom of the container, the eddy current enables metal atoms at the bottom of the container to randomly move at high speed, and the atoms collide and rub with each other to generate heat energy: the alternating magnetic field unit 300 can generate both an alternating magnetic field and heat energy. Specifically, after alternating current is introduced into the alternating magnetic field component 300, a high-frequency alternating magnetic field H1 is generated, magnetic lines of force in the magnetic field pass through the bottom of the container, strong eddy currents 10 are generated in the container due to electromagnetic induction, the eddy currents 10 enable metal atoms at the bottom of the container to move randomly at high speed, and the atoms collide and rub with each other to generate heat energy. Therefore, the alternating magnetic field component can be used for vibrating the magnetostrictive component to remove scale, and meanwhile, the magnetostrictive component can be heated, so that the structure of the container is simplified. According to the embodiment of the invention, when the heating component is an electromagnetic heating component, the heating component and the alternating magnetic field component can be combined into a whole, that is, the alternating magnetic field component can generate both an alternating magnetic field and heat energy. This simplifies the structure of the container and reduces the cost.
According to an embodiment of the present invention, the container may further include: an IH wire coil. The IH wire coil comprises a first coil and a second coil which are arranged in a surrounding mode, and the first coil and the second coil are used for generating a magnetic field and heating respectively. According to an embodiment of the present invention, the IH coil defines therein a magnetic field region in which the magnetic field generating coil of the alternating magnetic field part 300 is disposed and a heating region in which the heating coil of the heating part is disposed. According to the embodiment of the invention, the IH wire coil is adopted for heating, the bottom of the container is not required to be in contact with the coil disk, and therefore poor heat transfer effect caused by poor contact between the bottom of the container and the heating component in the vibration process can be avoided. According to the embodiment of the invention, the IH wire coil can heat the container, and the IH wire coil can also generate a magnetic field, so that the magnetostrictive component is deformed and vibrated, and the purposes of heating and descaling are achieved.
In another aspect of the invention, the invention provides a domestic appliance. According to an embodiment of the invention, the domestic appliance comprises the container described above, whereby the domestic appliance has all the features and advantages of the container described above, which are not described in detail herein. Generally, the life electric appliance has higher quality. According to an embodiment of the invention, the domestic appliance may comprise a kettle or a health preserving kettle. Therefore, the water jug and the health preserving jug can have higher quality.
According to an embodiment of the present invention, the life appliance may further include: a control device and a descaling key. Wherein, the control device is electrically connected with the alternating magnetic field component of the container, and the descaling key is connected with the control device. When a user presses the descaling key, the control device is utilized to enable the alternating magnetic field component to generate an alternating magnetic field, and the magnetostrictive component deforms and vibrates under the action of the alternating magnetic field, so that the descaling purpose is achieved, and the descaling key is simple to operate and convenient to use.
According to an embodiment of the present invention, the life appliance may further include: the foot pad is arranged at the bottom of the living electric appliance. In particular, the foot pad can be a silica gel foot pad. Therefore, the vibration and noise can be prevented from being transmitted downwards, and the influence on the desk and the like is reduced.
In another aspect of the invention, a method of descaling a vessel is provided. According to an embodiment of the present invention, the container may be the container described above, and thus, the container may have the same features and advantages as the container described above, and thus, will not be described herein again. Overall, the container can alleviate or solve the problem of early switch tripping, and has high quality. According to an embodiment of the invention, a method of descaling a vessel comprises: and controlling the alternating magnetic field component to generate an alternating magnetic field, and enabling the magnetostrictive component to vibrate under the alternating magnetic field so as to descale the container. Therefore, the automatic descaling of the container can be realized, the difficulty of manual descaling is solved, and the container is ensured to have higher quality. According to an embodiment of the invention, the method may further comprise: after the container receives the descaling command, the alternating magnetic field component is controlled to generate an alternating magnetic field. Specifically, the descaling program of the container can be started through a descaling button on the container, so that an alternating magnetic field is generated, the magnetostrictive component vibrates, and the container is descaled. The mode of descaling is not particularly limited, and can be selected by those skilled in the art according to the circumstances. For example, according to an embodiment of the present invention, a descaling period may be set during the use of the container to descale the container. Therefore, the scale removal is carried out in the using process of the container, the attachment of impurity ions to the container can be weakened, and the formation of scale is further slowed down. The descaling time needs to be further designed, and if the descaling time is short, the descaling time may result in unclean cleaning and affect the use of the container. If the descaling time is long, power consumption is increased. According to embodiments of the present invention, the descaling time may be 10-60 s. This can significantly reduce the adhesion of scale and improve the cleaning effect. According to further embodiments of the present invention, the vessel may be descaled after the vessel has been operated a predetermined number of times. Therefore, the scale can be uniformly cleaned after the container is used for a period of time, and the use is convenient. Further design is required for the predetermined number of times, and if the predetermined number of times is less, the scale formed in the container is less, and the use of the container is not affected, and the power consumption is increased when the descaling is performed. If the predetermined number of times is large, scale is formed in the container, which makes cleaning difficult and also increases power consumption. The predetermined number of times may be 5-20 times according to an embodiment of the present invention. Thereby, the efficiency and effect of descaling are improved.
