Description

Technical Field

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

[0002] A multi-burner induction cooker is an induction cooker device with multiple independent heating zones, capable of heating multiple pots and pans simultaneously. Currently, most multi-burner induction cookers have an internal air duct design as a single structure, with a fixed air intake path during heat dissipation.

[0003] When only one or both ends are in use, the fan still needs to draw air in through the air inlet according to the predetermined air intake path. Because the air duct is fixed, the drawn-in cold air cannot specifically dissipate heat from the heating element of the working induction cooker, but instead flows dispersed throughout the entire internal space, resulting in reduced heat dissipation efficiency for the same power consumption. Utility Model Content

[0004] The purpose of this invention is to provide a multi-head induction cooker with a heat dissipation component. By setting an interval structure to divide the inner cavity of the bottom shell into independent chambers, and with a switching structure that can switch the air intake path, targeted heat dissipation of the heating components in different working states can be achieved, thereby improving heat dissipation efficiency and reducing energy consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-head induction cooker with a heat dissipation component, comprising a bottom shell and a heating panel, wherein the bottom shell is fixedly connected to the heating panel by screws, and a heating component and a heat dissipation structure for dissipating heat from the heating component are provided between the bottom shell and the heating panel, wherein a controller electrically connected to the heating component and the heat dissipation structure is installed inside the bottom shell, and the cable of the controller extends through the bottom shell to the outside of the bottom shell. The heat dissipation structure includes a partition structure that divides the inner cavity of the bottom shell into four chambers. The bottom shell has an air outlet in the middle for discharging hot air, an air inlet in the side wall of the bottom shell, a fan below the air outlet, and a switching structure that can select different air inlet paths in the middle of the bottom shell.

[0006] Preferably, the spacer structure includes a first air guide plate, which is fixedly connected to the bottom shell, and one end of the first air guide plate is arc-shaped.

[0007] Preferably, the first air guide plate is provided in four sets, and a ventilation opening for air intake is left between the arc-shaped ends of two adjacent sets of the first air guide plate. One end of each ventilation opening is connected to the chamber, and the other end of the ventilation opening is connected to the air outlet.

[0008] Preferably, each of the chambers is fixed with a second air guide plate, and the four second air guide plates are respectively located at the four corners of the bottom shell cavity.

[0009] Preferably, the second air guide plate is arc-shaped, and the air inlet is located on one side of the air guide plate.

[0010] Preferably, the switching structure includes a rotating motor, which is fixed to the bottom of the base shell by screws. A rotating rod is rotatably connected to the upper surface of the middle part of the base shell, and the output end of the rotating motor is rotatably connected to the rotating rod.

[0011] Preferably, the switching structure further includes a stop block capable of blocking the vent, wherein two sets of the stop blocks are provided, the two sets of the stop blocks being arranged at 90° apart, and an elastic component allowing the stop blocks to move radially is installed inside the rotating rod.

[0012] Preferably, the elastic component includes a guide rod fixed to one side of the stop block, a slot is provided on the outer wall of the rotating rod, the guide rod is slidably connected in the slot, a spring is fixed in the slot, and one end of the spring is fixedly connected to the guide rod.

[0013] Preferably, one side of the baffle is arc-shaped, and the arc-shaped surface of the baffle abuts against the arc-shaped surface of the first air guide plate. Two sets of guide rods are provided on one side of each baffle.

[0014] Preferably, the heating assembly includes a heating wire electrically connected to the controller and a bracket providing a mounting position for the heating wire. The bracket is fixedly connected to the bottom shell, and the bottom of the bottom shell is equipped with support legs.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. The partition structure of this utility model divides the inner cavity of the bottom shell into four independent chambers, each chamber corresponding to a heating component. With the help of the second air guide plate, the airflow is guided to flow precisely to the heating area that is working, avoiding the dispersion of cold air in non-working areas and ensuring that the heat dissipation resources are concentrated on the components that need heat dissipation.

[0016] 2. The switching structure of this utility model can block the ventilation openings corresponding to non-working chambers by blocking the blocks, so that air does not need to be supplied to all chambers at the same time. The cold air drawn in by the fan enters only through the air inlet of the working chamber. By closing the air duct of the idle area, the ineffective work of the fan is reduced, and the overall energy consumption is reduced while ensuring the heat dissipation effect.

[0019] 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.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a multi-burner induction cooker with a heat dissipation component, including a bottom shell 1 and a heating panel 2. The bottom shell 1 provides an installation carrier for the internal components, and the heating panel 2 serves as a working surface for supporting cookware. The bottom shell 1 is fixedly connected to the heating panel 2 by screws. A heating component 3 and a heat dissipation structure 4 for dissipating heat from the heating component 3 are arranged between the bottom shell 1 and the heating panel 2. The heating component 3 generates heat to heat the cookware, and the heat dissipation structure 4 operates synchronously to remove heat and prevent the component from being damaged due to high temperature. A controller 5 is installed inside the bottom shell 1 and is electrically connected to the heating component 3 and the heat dissipation structure 4. The controller 5 receives external commands, such as switching and power adjustment, and controls the start / stop and power of the heating component 3. At the same time, it adjusts the operating mode of the heat dissipation structure 4 according to the heating status. The cable of the controller 5 passes through the bottom shell 1 and extends to the outside of the bottom shell 1. The cable extends to the outside for connecting to a power supply and a control terminal. The controller 5 of the multi-burner induction cooker is prior art. In this application, it is also used to control the rotation of the rotary motor 4061 to rotate a certain angle, which will not be described in detail here.

[0021] Please see Figure 1-5The heat dissipation structure 4 includes a partition structure 402 that divides the inner cavity of the bottom shell 1 into four chambers 401. The partition structure 402 divides the interior of the bottom shell 1 into independent spaces, and each chamber 401 corresponds to a heating component 3, so that the airflow flows in an independent area, solving the problem of cold air dispersion in traditional overall air ducts. The bottom shell 1 has an air outlet 403 for hot air discharge in the middle, and an air inlet 404 is opened on the side wall of the bottom shell 1. A fan 405 is arranged below the air outlet 403. Cold air enters from the side wall air inlet 404, flows through the heating component 3 and becomes hot air, and finally is discharged from the middle air outlet 403, forming a directional airflow circulation. The bottom shell 1 has a switching structure 406 that can select different air intake paths in the middle.

[0022] The fan 405 provides power to accelerate airflow; the switching structure 406 controls the entry of cold air into a specific chamber 401 by changing the on / off state of the air duct. It should be noted that in this application, two chambers 401 are grouped together, and the switching structure 406 can ensure that four groups of chambers 401 are opened simultaneously, or only two groups of chambers 401 are opened simultaneously.

[0023] Please see Figure 1-5 The partition structure 402 includes a first air guide plate 4021, which is fixedly connected to the bottom shell 1. One end of the first air guide plate 4021 is arc-shaped. The first air guide plate 4021 physically separates the chamber 401, and the arc-shaped end guides the airflow to converge towards the central air outlet 403, reducing wind resistance.

[0024] The first air guide plate 4021 is provided in four sets. A ventilation opening 4022 for air intake is provided between the arc-shaped ends of two adjacent sets of the first air guide plate 4021. One end of each ventilation opening 4022 is connected to the chamber 401, and the other end is connected to the air outlet 403. The ventilation opening 4022 serves as a connecting channel between the chamber 401 and the air outlet 403, allowing hot air from each chamber 401 to independently flow into the air outlet 403.

[0025] Each of the chambers 401 is equipped with a second air guide plate 4023, and the four second air guide plates 4023 are located at the four corners of the inner cavity of the bottom shell 1. The second air guide plates 4023 guide the cold air entering from the side wall air inlet 404 and flow along the corners of the chambers 401 to the heating assembly 3.

[0026] The second air guide plate 4023 is arc-shaped, and the air inlet 404 is located on one side of the air guide plate. The arc-shaped second air guide plate 4023 smoothly directs the airflow.

[0027] Please see Figure 1-5The switching structure 406 includes a rotary motor 4061, which is fixed to the bottom of the base shell 1 by screws. A rotating rod 4062 is rotatably connected to the upper surface of the middle part of the base shell 1. The output end of the rotary motor 4061 is rotatably connected to the rotating rod 4062. The rotary motor 4061 provides rotational power, driving the rotating rod 4062 to rotate in the middle of the base shell 1. The rotation angle of the rotating rod 4062 determines the position of the subsequent stop 4063. The rotary motor 4061 is a stepper motor, which can rotate 90° or 45° and can rotate in both directions.

[0028] Please see Figure 1-5 The switching structure 406 further includes a stop block 4063 capable of blocking the vent 4022. Two sets of stop blocks 4063 are provided, positioned at 90° intervals. An elastic component allowing radial movement of the stop blocks 4063 is installed within the rotating rod 4062. The stop blocks 4063 rotate with the rotating rod 4062. When the stop block 4063 aligns with the vent 4022, it blocks the channel. The two sets of 90°-distributed stop blocks 4063 can simultaneously block two adjacent vents 4022, allowing the other two chambers 401 to connect with the air outlet 403. This achieves the closing and opening of two chambers 401, preventing the two sets of induction cooker burners from being located within unopened chambers 401 when using the two sets of induction cooker burners.

[0029] The elastic component includes a guide rod 4064 fixed to one side of the stop block 4063. A slot 4065 is formed on the outer wall of the rotating rod 4062. The guide rod 4064 is slidably connected within the slot 4065. A spring 4066 is fixed within the slot 4065, with one end of the spring 4066 fixedly connected to the guide rod 4064. The guide rod 4064 slides within the slot 4065, restricting the movement direction of the stop block 4063. The elastic force of the spring 4066 pushes the guide rod 4064, ensuring that the stop block 4063 always presses against the first air guide plate 4021. The elastic component allows the stop block 4063 to extend and retract radially along the rotating rod 4062, ensuring that the stop block 4063 remains in contact with the arcuate surface of the first air guide plate 4021 during rotation.

[0030] One side of the baffle 4063 is arc-shaped, and the arc-shaped surface of the baffle 4063 abuts against the arc-shaped surface of the first air guide plate 4021. Two sets of guide rods 4064 are provided on one side of each baffle 4063.

[0031] Please see Figure 1-5The heating assembly 3 includes a heating wire 301 electrically connected to the controller 5 and a bracket 302 providing a mounting position for the heating wire 301. The bracket 302 is fixedly connected to the bottom shell 1, and a support leg 6 is installed on the bottom of the bottom shell 1. The controller 5 controls the heating wire 301 to generate heat, and the bracket 302 fixes the position of the heating wire 301 to ensure a stable distance between it and the heating panel 2, thus ensuring heating efficiency. The support leg 6 raises the bottom of the bottom shell 1, reserving heat dissipation space for the fan 405 below the air outlet 403, while also preventing heat conduction caused by the bottom shell 1 directly contacting the tabletop.

[0032] When in use, if one or two heating zones are activated, the controller 5 drives the rotating motor 4061 of the switching structure 406 to operate, causing the rotating rod 4062 to rotate 90°. At this time, under the action of the elastic component, the two sets of baffles 4063 press against the arc-shaped surface of the first air guide plate 4021 corresponding to the non-working chamber 401, blocking the ventilation opening 4022; thus closing two chambers 401 and opening the other two chambers 401, preventing the two sets of induction cooker burners from being in the unopened chambers 401 when using the two sets of induction cooker burners.

[0033] If 3-4 heating zones are activated, the rotating motor 4061 drives the rotating rod 4062 to rotate 45°, so that the two stops 4063 disengage from all the vents 4022, keeping the ventilation path of all chambers 401 unobstructed. After the fan 405 is started, cold air from outside enters through the air inlet 404 on the side wall of the bottom shell 1. Guided by the second air guide plate 4023, the cold air flows to the working chamber 401, absorbs heat as it flows through the heating element 3, and becomes hot air. The hot air flows into the middle of the bottom shell 1 through the vent 4022 corresponding to the working chamber 401, and is finally discharged from the air outlet 403, completing the heat dissipation cycle.

[0034] 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.
