[0024] In order to further explain the technical means and effects adopted by the present application to achieve the predetermined purpose, the specific implementation methods, structures, features and effects of the present application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0025] Combination Figure 1-Figure 8 As shown, an electromagnetic induction heating device of an embodiment specifically includes a housing, an electromagnetic induction heating element 2 disposed in the housing, and a control circuit board electrically connected to the electromagnetic induction heating element 2. The housing includes a main housing 1 having an open side and a panel 4 mounted on the open side of the main housing 1. The main housing 1 generally includes a bottom housing 11 and a shell frame 12. The bottom housing 11 and the shell frame 12 are an integral structure or the bottom housing 11 is fixedly mounted on the other side of the shell frame 12 relative to the open side. The electromagnetic induction heating element 2 is fixed to the bottom housing 11 by a fixing bracket 29. An electrical box 3 is also provided on the bottom housing 11. The control circuit board is built into the electrical box 3 to protect the control circuit board.

[0026] The housing also includes: a step inner plate 122, fixed to the inner peripheral edge of the top surface of the opening side of the main housing 1; a vertical baffle plate 5, longitudinally extending from the inner peripheral edge of the step inner plate 122 to the opening side of the main housing 1; and a support top plate 6, fixed to the outer peripheral edge of the top surface of the step inner plate 122; wherein the panel 4 is fixedly assembled on the support top plate 6, so that a groove 7 is formed between the peripheral edge of the panel 4 and the step inner plate 122, which is concave relative to the main housing 1. With such a structure, a groove 7 is formed between the step inner plate 122 and the support top plate 6 through the vertical baffle plate 5, and the groove 7 is arranged between the top surface of the main housing 1 and the panel 4, so that the panel 4 forms a suspended design relative to the main housing 1, making the overall appearance of the housing consistent and beautiful, not only avoiding the defect of the prior art that the panel 4 and the main housing 1 are prone to assembly seams due to the assembly process, which affects the overall appearance of the housing, but also providing a hidden installation position for setting an atmosphere light or a decorative belt on the housing.

[0027] The opening side of the main housing 1 refers to the opening side of the housing frame 12 relative to the bottom housing 11. The top surface of the opening side of the main housing 1 has the same meaning as the top surface of the opening side of the housing frame 12. "Top" is relative to the bottom housing 11, not the highest position of the electromagnetic induction heating device.

[0028] The orthographic projection of the support top plate 6 on the plane where the top surface of the opening side of the main housing 1 is located is located on the step inner plate 122. In a preferred embodiment, the step inner plate 122 is arranged parallel to the support top plate 6, and the size of the support top plate 6 is preferably 5-50 mm smaller than that of the step inner plate 122, so as to ensure that the panel 4 has a better floating visual effect relative to the main housing 1.

[0029] The inner wall of the vertical baffle plate 5 is provided with a reinforcing rib 51. The reinforcing rib 51 is one or more, and the reinforcing rib 51 can improve the strength of the vertical baffle plate 5, ensuring that the panel 4 is firmly installed relative to the main housing 1 and the overall reliability.

[0030] The top surface of the opening side of the main housing 1 has a guide surface 121, which is an inclined surface or a chamfered curved surface. The guide surface 121 is provided so that the outer side of the groove 7 is opened, and a transition is formed between the top surface of the main housing 1 and the groove 7, which is conducive to ensuring the continuity and consistency of the overall appearance structure of the housing.

[0031] The top surface of the supporting top plate 6 is provided with a glue groove 61, and the panel 4 is glue-fixed to the supporting top plate 6. The number of the glue groove 61 is not limited to one, and a tape or glue is provided in the glue groove 61, and the panel 4 is glue-fixed to the supporting top plate 6 by using the tape or glue in the glue groove 61. This assembly structure is easy to operate, and it is also convenient to remove the panel 4 later to perform maintenance operations on the electromagnetic induction heating element 2 and the control circuit board.

[0032] Among them, the shell frame 12, the step inner plate 122, the vertical baffle plate 5 and the supporting top plate 6 of the main shell 1 are an integrally formed structure; or, the shell frame 12 and the step inner plate 122 of the main shell 1 are an integrally formed structure, and the vertical baffle plate 5 and the supporting top plate 6 are an integrally formed structure.

[0033] Among them, an ambient light or a decorative strip is arranged in the groove 7 to improve the overall aesthetics of the housing.

[0034] The vertical height of the vertical baffle 5 is between 10 and 50 mm. When the vertical height of the vertical baffle 5 is less than 10 mm, the suspension effect of the panel 4 relative to the main housing 1 is not obvious; and when the vertical height of the vertical baffle 5 is greater than 50 mm, it is easy to cause the size of the groove 7 to be too large and affect the consistency of the overall appearance of the housing.

[0035] In one embodiment, the electromagnetic induction heating element 2 includes a water inlet 21, a water outlet 22, a heating tube 23, an insulating tube 24 sleeved on the outer side of the heating tube 23, and an electromagnetic coil 25 wound on the insulating tube 24. The electromagnetic coil 25 is electrically connected to the control circuit board in the electrical box 3. The control circuit board provides an alternating current to the electromagnetic coil 25 to generate an alternating magnetic field, so that the heating tube 23 is heated by induction.

[0036] A heating chamber 26 is provided between the heating tube 23 and the insulating tube 24 . One of the water inlet 21 and the water outlet 22 is connected to the heating chamber 26 , while the other one is connected to the inner cavity of the heating tube 23 .

[0037] Among them, the panel 4 is made of insulating material, such as glass; a heat dissipation gap 8 is reserved between the panel 4 and the electromagnetic induction heating element 2, and the heat generated by the electromagnetic coil 25 can be quickly dissipated through the heat dissipation gap 8, ensuring that the electromagnetic induction heating device works stably and reliably.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
