Description

Technical Field

[0001] This utility model relates to the field of multi-burner induction cooker technology, specifically a noise reduction component and a multi-burner induction cooker. Background Technology

[0002] The principle of an induction cooker is electromagnetic induction. It uses alternating current to generate an alternating magnetic field with a constantly changing direction through a coil. Eddy currents will appear inside a conductor in an 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 heats up the conductor, thus achieving heating. As a kitchen appliance that can support independent control of multiple burners at the same time, a multi-burner induction cooker can save space and improve cooking efficiency during use. However, in actual use, multi-burner induction cookers generate some vibration during operation due to the cooling fan, and the airflow also generates noise due to the impact with the inside of the cooker. This noise is transmitted to the outside through the ventilation holes. Excessive noise will reduce the user experience of using the multi-burner induction cooker and thus affect the user's mood. Therefore, we need to propose a noise reduction component and a multi-burner induction cooker. Utility Model Content

[0003] The purpose of this invention is to provide a noise reduction component and a multi-burner induction cooker. By setting a heat dissipation mechanism inside the housing, the heat dissipation mechanism can draw out excess heat from inside the multi-burner induction cooker, reducing the impact of heat. At the same time, it can reduce the collision range of airflow with internal components. Furthermore, by covering the heat dissipation mechanism with a noise reduction structure, the noise impact of airflow is further reduced, thereby reducing the noise during the use of the multi-burner induction cooker and solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-burner induction cooker, comprising: The induction cooker has an outer shell and two heating zones on its upper surface. Two control panels are located on one side of the outer shell. Heat dissipation holes are provided on both sides of the outer shell adjacent to the control panels.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a multi-burner induction cooker, comprising: The induction cooker has an outer shell 1 and two heating zones 2 on the upper surface of the outer shell 1. Two control panels 4 are provided on one side of the outer shell 1. Heat dissipation holes 3 are provided on both sides of the outer shell 1 adjacent to the control panels 4. Dust prevention mechanisms 6 are installed in the heat dissipation holes 3. The heat dissipation holes 3 increase the heat dissipation space inside the outer shell 1.

[0019] In this embodiment, the dustproof mechanism 6 includes a plate frame 61, on which a dustproof mesh plate 63 is installed, and two sets of positioning bolts 62 that are bolted to the outer shell 1 of the induction cooker are inserted into one side of the plate frame 61. By installing a dustproof mesh plate 63 inside the frame 61, the dustproof mesh plate 63 can effectively block external dust from entering the heat dissipation mechanism 7 through the heat dissipation holes 3, avoiding dust accumulation that affects the air circulation performance. At the same time, the positioning bolts 62 facilitate the stable connection between the frame 61 and the outer shell, and are easy to disassemble, making it convenient to clean or replace the dustproof mesh plate 63.

[0020] Specifically, both sides of the heat dissipation hole 3 are provided with limiting grooves 31 for the plate frame 61 to be inserted. The opening ends of the two sets of heat dissipation holes 3 are respectively opened at both ends of one side of the induction cooker shell 1. The limiting grooves 31 can provide precise installation positioning for the plate frame 61, ensuring stable assembly of the dustproof mechanism 6. The openings of the two sets of heat dissipation holes 3 are distributed at both ends of one side of the shell, which facilitates the installation of the plate frame 61.

[0021] Please see Figure 1-5 In a further preferred embodiment, the multi-burner induction cooker also includes two sets of protective mechanisms 5 installed on one side of the induction cooker housing 1. Each set of protective mechanisms 5 includes a fixing block 51 and a protective frame 52. The protective frame 52 is rotatably mounted on the fixing block 51. A transparent silicone sheet 53 is provided inside the protective frame 52. The control panel 4 is located in the inner cavity of the protective frame 52. The protective frame 52 and the transparent silicone sheet 53 can isolate the control panel 4 from the outside world, effectively preventing oil and water stains from corroding the control panel 4. At the same time, the protective frame 52 can be flipped on the fixing block 51, which does not affect the operation of the panel through the transparent silicone sheet 53, and makes it convenient to open for panel maintenance, thus improving practicality.

[0022] Please see Figure 1-5 In this embodiment, a noise reduction component is installed on a multi-burner induction cooker described above, and also includes a heat dissipation mechanism 7. The air inlet of the heat dissipation mechanism 7 is located at the lower end of the induction cooker shell 1, the air guide end of the heat dissipation mechanism 7 is installed in the inner cavity of the induction cooker shell 1, and a noise reduction structure 8 is provided on the outside of the heat dissipation mechanism 7 to reduce the airflow noise inside the heat dissipation mechanism 7.

[0023] The heat dissipation mechanism 7 optimizes the air intake and air guide paths to ensure that the heat dissipation efficiency is adapted to the high power requirements of multi-burner induction cookers. At the same time, the external noise reduction structure 8 can specifically reduce the airflow noise during the heat dissipation process, solve the problem of excessive noise in traditional heat dissipation systems, and improve user comfort.

[0024] Please see Figure 1-5 It is worth noting that the heat dissipation mechanism 7 includes an air inlet component 71 and a flow guide component 72. The air inlet component 71 is installed on the lower surface of the induction cooker shell 1, and the flow guide component 72 is installed in the inner cavity of the induction cooker shell 1. The air inlet end of the flow guide component 72 is connected to the air outlet end of the air inlet component 71, and the air outlet end of the flow guide component 72 is connected to two sets of heat dissipation holes 3 respectively.

[0025] An orderly air duct is formed between the air intake component 71 and the air guide component 72. The air intake end draws air from the lower end of the induction cooker shell 1, and the air guide end precisely directs the airflow to the heat dissipation hole 3, so that the internal heat is discharged in an orderly manner with the airflow, avoiding heat dissipation dead corners caused by turbulence, and improving the heat dissipation efficiency of multi-burner induction cookers.

[0026] Furthermore, the air intake assembly 71 includes an air intake square tube 711 and a connecting tube 712. The air intake square tube 711 is fixedly connected to the lower surface of the induction cooker shell 1. The connecting tube 712 is located at one end of the upper surface of the air intake square tube 711 and extends into the inner cavity of the induction cooker shell 1. A fan 713 is installed in the inner cavity of the connecting tube 712. A dustproof mesh cover 714 is snapped onto the air intake end of the air intake square tube 711, and a locking block 715 is fixedly connected to both sides of the dustproof mesh cover 714. A slot 716 for the locking block 715 to be inserted is opened on both sides of the air intake square tube 711. The fan 713 enhances the air circulation speed, while the dustproof mesh cover 714 filters the incoming air, preventing dust and impurities from entering through the air intake end and blocking the airflow guide assembly 72. At the same time, the cooperation between the locking block 715 and the slot 716 makes the dustproof mesh cover 714 easy to install and remove, facilitates regular cleaning, and ensures smooth air intake.

[0027] Preferably, the airflow guiding component 72 includes two sets of air diffusers 723 and a diversion pipe 721 connected to the connecting pipe 712. Both ends of the diversion pipe 721 are connected to side pipes 722. The opposite end of each pair of side pipes 722 to the diversion pipe 721 is connected to a set of air diffusers 723, and the opening end of the air diffuser 723 is connected to the heat dissipation hole 3. The diversion pipe 721 distributes the airflow evenly to each set of side pipes 722, while the air diffuser 723 increases the contact area between the airflow and the heat dissipation hole 3, so that the airflow is discharged from the heat dissipation hole 3 more evenly, avoiding uneven heat dissipation caused by local airflow concentration, improving the heat dissipation speed, and reducing wind resistance and noise.

[0028] Multiple sets of first heat sinks 724 are threaded through the shunt pipe 721, and multiple sets of second heat sinks 725 are inserted into each of the side pipes 722. The multiple sets of first heat sinks 724 and multiple sets of second heat sinks 725 are arranged at equal intervals. In addition, the first heat sinks 724 and second heat sinks 725 increase the contact area between the air guiding component 72 and the internal air, accelerating the transfer of heat from the component to the airflow. The equal interval arrangement ensures that the first heat sinks 724 and second heat sinks 725 absorb and transfer heat more evenly, and together with the airflow, more heat is carried away, further enhancing the heat dissipation effect.

[0029] Please see Figure 1-5 The noise reduction structure 8 includes a thermally conductive silicone layer 81 and a sound-absorbing cotton layer 82. The sound-absorbing cotton layer 82 is disposed on the outside of the thermally conductive silicone layer 81, and the thermally conductive silicone layer 81 is attached to the outside of the airflow guiding component 72. The thermally conductive silicone layer 81 is tightly attached to the airflow guiding component 72, which can help to dissipate heat from the surface of the component and enhance heat dissipation capacity. The outer sound-absorbing cotton layer 82 can effectively absorb the noise generated when the airflow passes through the airflow guiding component 72, thereby improving the quietness of the multi-burner induction cooker.

[0030] When in use, multiple appliances can be heated simultaneously through two independent heating zones 2, while the control panel 4 controls each heating zone 2 separately, which is convenient and practical. When the fan 713 is used to dissipate heat in the multi-head induction cooker, the operation of the fan 713 will cause airflow and generate a certain amount of noise.

[0031] At this time, the fan 713 of the air intake component 71 draws in air from the lower end of the induction cooker shell 1, and filters impurities through the dust cover 714. The airflow enters the diversion pipe 721 of the air guide component 72 through the connecting pipe 712. The airflow is then distributed to each group of side pipes 722 through the diversion pipe 721. The air is then guided by the air diffuser 723 to the heat dissipation holes 3 on both sides of the shell and discharged. During the airflow process, the first heat sink 724 and the second heat sink 725 increase the heat dissipation area and accelerate heat transfer. At the same time, the increased airflow area during the exhaust process reduces wind resistance and noise. Meanwhile, the thermally conductive silicone layer 81 assists in heat dissipation, and the sound-absorbing cotton layer 82 absorbs the noise of the airflow to the air guide component, ultimately achieving low-noise operation of the multi-head induction cooker.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
