[0002] Induction cooker, also known as electromagnetic stove, is the product of modern kitchen revolution. It does not need open flame or conduction heating but allows heat to be generated directly at the bottom of the pot, so the thermal efficiency has been greatly improved. Induction cooker is an electrical cooking appliance made by electromagnetic induction heating principle, which consists of high-frequency induction heating coil (i.e. excitation coil), high-frequency power conversion device, controller and ferromagnetic material pot bottom cooker and other parts.

[0003] Existing induction cookers mostly achieve the insect-proof effect by using insect-repellent lamps, insect-repellent drugs or adding insect-proof nets and insect-proof covers inside the induction cooker. Adding these components also increases the labor cost and material cost, and adding insect-proof covers, insect-proof nets and other components also reduces the heat dissipation effect of the induction cooker. Summary of the invention

[0004] The object of the present invention is to provide a protective structure and a household appliance with high efficiency in heat dissipation, which can solve the existing conflict between heat dissipation and protection.

[0005] To achieve the above-mentioned purpose, the specific technical solutions of the protective structure and household appliance with high efficiency heat dissipation of the present invention are as follows:

[0006] A protective structure with efficient heat dissipation includes a bottom shell component, a receiving groove is formed inside the bottom shell component, a panel component cover is arranged at the opening of the receiving groove to form a closed receiving chamber, a rib plate is arranged in the receiving chamber, the rib plate surrounds the receiving chamber to form a closed protective chamber, components to be protected are arranged in the protective chamber, the heat dissipation air outlet in the protective chamber is greater than the heat dissipation air inlet, so as to guide the heat dissipation airflow to pass through the protective chamber.

[0007] Furthermore, an air inlet and an air outlet are provided on the side wall of the accommodating chamber.

[0008] Furthermore, the rib plate is disposed around the inner side of the side wall of the accommodating chamber, and a buffer chamber is formed between the rib plate and the side wall of the accommodating chamber.

[0009] Furthermore, an air flow channel is formed between the top surface of the rib plate and the bottom surface of the panel assembly, and the heat dissipating air flow can pass through the protective chamber via the air flow channel.

[0010] Furthermore, an air inlet fan is provided near the air inlet in the accommodating chamber, and an air exhaust fan is provided near the air outlet. The air inlet fan introduces the heat dissipation airflow into the accommodating chamber, and the exhaust fan exhausts the heat dissipation airflow from the accommodating chamber.

[0011] Furthermore, the rotation speed of the exhaust fan is greater than the rotation speed of the inlet fan, so as to form a pressure difference in the accommodating chamber, thereby prompting the heat dissipation airflow to flow into the accommodating chamber from the air inlet.

[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an efficient heat dissipation protection structure and a household appliance of the present invention in conjunction with the accompanying drawings.

[0024] like Figures 1 to 6As shown, the induction cooker is taken as an example to illustrate the efficient heat dissipation protection structure of the present invention. The induction cooker includes a bottom shell assembly 10, a receiving groove is formed inside the bottom shell assembly 10, and a panel assembly 20 is covered at the opening of the receiving groove to form a closed receiving chamber, and various components of the induction cooker are installed in the receiving chamber. It should be noted that the efficient heat dissipation protection structure of the present invention can also be applied to other forms of household appliances, and is not limited to those shown in the figure, as long as it is a household appliance that needs protection and heat dissipation.

[0025] Specifically, a rib plate 30 is provided in the accommodating chamber, and the rib plate 30 surrounds the accommodating chamber to form a closed protective chamber 11, and the components to be protected are arranged in the protective chamber 11. Preferably, in this embodiment, the rib plate 30 is surrounded and arranged on the inner side of the side wall of the accommodating chamber, and a buffer chamber 12 is formed between the rib plate 30 and the side wall of the accommodating chamber.

[0026] Furthermore, an air inlet 13 and an air outlet 14 are provided on the side wall of the accommodating chamber, and an air flow channel is formed between the top surface of the rib plate 30 and the bottom surface of the panel assembly 20, so that the heat dissipation airflow can enter the interior of the accommodating chamber through the air inlet 13, flow through the protective chamber 11 through the air flow channel, and then be discharged from the accommodating chamber through the air outlet 14.

[0027] Furthermore, an air inlet fan 15 is provided at a position near the air inlet 13 in the accommodating chamber, and an exhaust fan 16 is provided at a position near the air outlet 14, wherein the air inlet fan 15 can introduce the heat dissipation airflow into the accommodating chamber, and the exhaust fan 16 can exhaust the heat dissipation airflow from the accommodating chamber. Preferably, the rotation speed of the exhaust fan 16 is greater than the rotation speed of the air inlet fan 15, so as to form a pressure difference in the accommodating chamber, thereby causing the heat dissipation airflow to flow from the air inlet 13 into the accommodating chamber.

[0028] Further, in this embodiment, a first accommodating groove 31 is formed on the rib plate 30 near the air inlet 13, and the air inlet fan 15 is disposed in the first accommodating groove 31. Correspondingly, a second accommodating groove 32 is formed on the rib plate 30 near the air outlet 14, and the exhaust fan 16 is disposed in the second accommodating groove 32. Therefore, since the rotation speed of the exhaust fan 16 is greater than the rotation speed of the air inlet fan 15, the heat dissipation air outlet volume in the protective chamber 11 will be greater than the heat dissipation air inlet volume, and the heat dissipation airflow can be better guided to pass through the protective chamber 11.

[0029] Furthermore, preferably, the air inlet fan 15 and the exhaust fan 16 are arranged at diagonal positions of the protective chamber 11. In the present embodiment, the protective chamber 11 is a rectangular structure, the first accommodating groove 31 is arranged at a corner, and the opening of the first accommodating groove 31 faces the interior of the protective chamber 11, and the second accommodating groove 32 is arranged at another opposite corner, and the opening of the second accommodating groove 32 faces the outside of the protective chamber 11. Thus, the inlet and outlet of the heat dissipation airflow can be further enhanced, thereby improving the heat dissipation efficiency.

[0030] See also Figures 1 to 6 The induction cooker of this embodiment is assembled and used as follows: the air inlet fan 15 and the exhaust fan 16 and the corresponding fan cover are fixedly mounted on the bottom shell assembly 10, the microcrystalline board and the cover bracket are bonded to form the panel assembly 20, and the panel assembly 20 is assembled and fixed to the bottom shell assembly 10 by screws. During operation, the air inlet fan 15 and the exhaust fan 16 are started at the same time, and the rotation speed of the exhaust fan 16 is greater than the rotation speed of the air inlet fan 15, that is, the exhaust efficiency is greater than the suction efficiency, so that a pressure difference is formed inside the accommodating chamber. Based on the pressure difference, the heat dissipation airflow enters the accommodating chamber from the air inlet 13 on one side of the bottom shell assembly 10, and further flows through the protective chamber 11 surrounded by the rib plate 30, and finally is discharged from the air outlet 14 on the other side of the bottom shell assembly 10 to achieve a cooling and heat dissipation effect.

[0031] The efficient heat dissipation protection structure and household appliance of the present invention form a closed cavity through the rib structure on the bottom shell component, which can prevent tiny insects from entering the cavity and prevent water from splashing into the cavity to avoid damage to components such as the main board in the cavity. At the same time, the negative pressure design in the cavity can also be used to dissipate heat with low consumption and high efficiency.

[0032] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
