A high-efficiency induction cooker

Abstract

This utility model discloses a high-efficiency induction cooker, belonging to the field of induction cooker technology. The induction cooker includes an induction cooker shell, a support assembly, and a heating assembly. The support assembly is installed on the induction cooker shell, and the heating assembly is arranged above the support assembly. A closing plate is installed at the top opening of the induction cooker shell. The support assembly and the heating assembly are installed in the cavity formed after the closing plate and the induction cooker shell are assembled. The heating assembly mainly consists of an electromagnetic coil group and a matching magnetic block. The traditional installation method of the matching magnetic block is changed. The magnetic block inserted in the electromagnetic coil group is moved to the bottom of the electromagnetic coil group, so that the electromagnetic coil group has more turns and is wound more tightly, which ensures the efficiency of the subsequent alternating magnetic field. Furthermore, the positioning post and spring group in the support assembly adjust the position of the heating assembly, thereby reducing the distance between the heating assembly and the closing plate.

Description

Technical Field

[0001] This utility model belongs to the field of induction cooker technology, specifically relating to a high-efficiency induction cooker. Background Technology

[0002] The principle of an induction cooker is electromagnetic induction. It uses alternating current passing through a coil to generate an alternating magnetic field with a constantly changing direction. Eddy currents will appear inside a conductor in the alternating magnetic field. This is caused by the eddy electric field driving the movement of charge carriers in the conductor. The Joule heating effect of the eddy currents causes the conductor to heat up, thus achieving heating.

[0003] Existing induction cookers mainly consist of a control panel, an electromagnetic coil, a magnetic block, and a support. The most crucial component is the electromagnetic coil. The power of an induction cooker is related to the number of turns of the coil and the position of the magnetic block. The smaller the number of turns of the coil and the more properly the magnetic block is distributed, the more the heating effect of the induction cooker will be enhanced.

[0004] In existing induction cookers, the number of coil turns is generally fixed, and there is a certain spacing between the circuits within the coil to allow space for the subsequent installation of the magnet. Although this method is stable in use, the spacing affects the number of coil turns on the coil, thus affecting the heating effect of the electromagnetic coil when it is working.

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A high-efficiency induction cooker includes an induction cooker shell and a heating element. The heating element is disposed on the induction cooker shell, and a circuit control system is installed on the upper surface of the induction cooker shell. The circuit control system is electrically connected to the heating element. A closing plate is installed at the top opening of the induction cooker shell, and a marking area is provided on the closing plate. The heating element increases its heat output power by shortening the spacing between the internal coils.

[0008] As a preferred technical solution of this utility model, the heating component includes a coil frame, an electromagnetic coil assembly, and a matching magnetic block. The coil frame is provided above the induction cooker shell, the electromagnetic coil assembly is bonded to the upper surface of the coil frame, the matching magnetic block is installed at the bottom of the coil frame, the electromagnetic coil assembly is electrically connected to the circuit control system, and the electromagnetic coil assembly is tightly wound by an electromagnetic ring.

[0009] As a preferred technical solution of this utility model, the mating magnetic block mainly consists of an inner ring insert, an outer ring insert, and a middle connecting block. The bottom end of the coil frame is provided with mounting grooves at equal intervals. The middle connecting block is installed in the mounting groove. An inner ring insert is installed at one end of the middle connecting block, and an outer ring insert is installed at the other end of the middle connecting block. The inner ring insert and the outer ring insert both penetrate the coil frame, with the inner ring insert entering the inner ring area of ​​the coil frame and the outer ring insert entering the outer area of ​​the coil frame.

[0010] As a preferred embodiment of the present invention, the heating component further includes a support block, and the support block is adhered to the upper surface of the electromagnetic coil assembly. The support block controls the minimum distance between the electromagnetic coil assembly and the closed plate.

[0011] As a preferred technical solution of this utility model, the heating component further includes a positioning arc plate, and positioning arc plates are installed at equal intervals at the edge of the coil frame, with positioning grooves opened in the positioning arc plates.

[0012] As a preferred technical solution of this utility model, it also includes a support component. The support component is installed on the induction cooker shell. The support component includes an internal support member, a support column and a positioning column. The internal support member is installed on the induction cooker shell. The support columns are installed at equal intervals on the internal support member. The positioning column is installed at the top of the support column. The positioning column is slidably inserted into the positioning groove. A spring assembly is sleeved on the outside of the positioning column. The positioning arc plate applies downward pressure to the spring assembly.

[0013] As a preferred embodiment of this utility model, the support assembly further includes a support base, on the side of the internal support component, which supports and positions the control panel in the induction cooker.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes a support component and a heating component, along with a circuit control system, to generate a constantly changing alternating magnetic field between the electromagnetic coil assembly and the mating magnetic block. This produces eddy currents, gradually increasing the temperature on the closed plate. Furthermore, the installation position of the mating magnetic block is altered during use, allowing the electromagnetic coil assembly to be tightly wound, increasing the number of coil turns. Combined with the large-volume mating magnetic block, this improves the overall efficiency of the induction cooker. The coordinated use of the spring assembly, positioning post, and positioning arc plate pushes the heating component to a position as close to the closed plate as possible without direct contact, shortening the heat transfer distance and ensuring more stable operation of the induction cooker.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0027] Example 1:

[0028] like Figure 1 and Figure 2As shown, this is a structural schematic diagram of the high-efficiency induction cooker in this embodiment. The induction cooker in this embodiment changes the distribution of the electromagnetic coil and the magnetic block, allowing the electromagnetic coil to be tightly wound together. Combined with the magnetic block at the lower end, this improves the overall power of the induction cooker. The induction cooker includes an induction cooker shell 1, a support component 2, and a heating component 3. The support component 2 is installed on the induction cooker shell 1, and the heating component 3 is arranged above the support component 2. A closing plate is installed at the top opening of the induction cooker shell 1. When the induction cooker is in use, the pot to be heated will be placed directly on the closing plate, and a marking area is provided on the closing plate to facilitate the stable placement of the pot within the marking area. The induction cooker shell 1 is equipped with a control circuit system, which is a commonly used control system in current induction cookers and is existing technology. Therefore, it will not be described in detail in this embodiment.

[0029] As attached Figure 3 As shown, this is a schematic diagram of the support component 2 in this embodiment. The support component 2 includes an internal support 21, a support column 22, and a positioning column 23. The internal support 21 is installed on the induction cooker shell 1, and the support column 22 is installed on the surface of the internal support 21. There are three sets of support columns 22. The positioning column 23 is fixedly installed at the top of the support column 22. A spring group 24 is sleeved on the outside of the positioning column 23. The positioning column 23 calibrates and locks the position of the heating component 3. When the heating component 3 is placed on the positioning column 23, the spring group 24 is squeezed by the weight of the heating component 3 and enters the storage mode. The spring group 24 will release its own elasticity, allowing the heating component 3 to move closer to the closing plate, reducing the distance between the heating component 3 and the closing plate, so that the heat generated by the heating component 3 can be conducted to the closing plate, and the pot placed on the closing plate can be stably heated. By shortening the distance between the heating component 3 and the closing plate, the heat conduction distance is reduced, ensuring the heating effect of the induction cooker itself.

[0030] It is worth noting that a support base 25 is installed on the side of the internal support component 21, and a control panel is placed on the top of the support base 25. The control panel is electrically connected to the control circuit system. By rotating the knob on the control panel, the power of the heating component 3 during operation can be controlled.

[0031] As attached Figure 4 , Figure 5 and Figure 6As shown, this is a schematic diagram of the structure of the heating component 3 in this embodiment. The heating component 3 includes a coil frame 31, an electromagnetic coil group 32, and a mating magnetic block 34. The coil frame 31 is provided above the support component 2. The electromagnetic coil group 32 is installed on the upper surface of the coil frame 31, and the mating magnetic block 34 is installed on the lower surface of the coil frame 31. There are multiple sets of mating magnetic blocks 34. The mating magnetic block 34 is mainly composed of an inner ring insert, an outer ring insert, and a middle connecting block. The bottom end of the coil frame 31 is provided with mounting grooves at equal intervals. The middle connecting block is installed in the mounting groove. An inner ring insert is installed at one end of the middle connecting block, and an outer ring insert is installed at the other end of the middle connecting block. The inner ring insert penetrates the coil frame 31 and enters the inner ring area of ​​the electromagnetic coil group 32. The outer ring insert penetrates the coil frame 31 and blocks the outer area of ​​the electromagnetic coil group 32.

[0032] It is worth noting that the electromagnetic coil assembly 32 is formed by tightly shrinking the coil, and after the electromagnetic coil assembly 32 is shrunk, it is directly glued to the upper surface of the coil frame 31. By removing the gap after the electromagnetic coil assembly 32 is shrunk, the number of turns of the electromagnetic coil assembly 32 itself is increased. In addition, when the magnetic block 34 is placed at the bottom of the electromagnetic coil assembly 32, it wraps the inner and outer sides of the electromagnetic coil assembly 32, making the overall heating effect of the heating component 3 more efficient.

[0033] As attached Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment, positioning arc plates 35 are installed at equal intervals at the edge of the coil frame 31. Positioning arc plates 35 are provided with positioning grooves. Positioning posts 23 are slidably inserted into the positioning grooves. Support blocks 33 are glued to the surface of the electromagnetic coil assembly 32. The support blocks 33 are used to control the distance between the electromagnetic coil assembly 32 and the closing plate to prevent the surface of the support blocks 33 from directly contacting the closing plate.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
