Description

Technical Field

[0001] This utility model relates to the technical field of handles for electric ceramic stoves, and particularly to a multi-burner electric ceramic stove. Background Technology

[0002] Ceramic cooktops are heated by nickel-chromium wire in a heating element. Because their heating principle is resistance heating, their radiation is far lower than that of induction cooktops and other electric heating appliances. Therefore, ceramic cooktops are widely used, often in multi-functional electric heating teaware for sterilization and heating, and also in hot pot stoves in homes and restaurants. Currently, the structure of a ceramic cooktop includes a cooktop body, a microcrystalline panel, a heating element fixed between the microcrystalline panel and the bottom shell, and a cooling fan. However, existing ceramic cooktops have the following problems: First, the heating element is directly fixed to the bottom shell, and the entire system uses resistance heating technology to generate heat. Since the internal structure of the cooktop is entirely conductive, if the heating element absorbs water, it can easily lead to electric leakage and other dangerous situations due to the poor overall insulation of the ceramic cooktop, compromising safe use. Second, to prevent the heat inside the ceramic cooktop from affecting electronic components (such as power boards), existing ceramic cooktops generally use cooling fans to improve heat dissipation and protect these components. However, the cooling efficiency of existing fans and air ducts is low, leaving electronic components in a high-temperature environment. Third, the heating element is directly fixed to the bottom shell, making disassembly and assembly difficult and hindering maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-head electric ceramic stove with high heat dissipation efficiency, high safety, and convenient maintenance of the heating device.

[0004] The purpose of this utility model is achieved as follows: A multi-burner ceramic cooktop includes a base, a microcrystalline plate, and multiple burner modules. The burner modules are housed within the base, with the microcrystalline plate covering the top opening of the base. Each burner module includes a heating element, a plastic mounting base, a circuit board, a fan, and multiple screws. The circuit board, fan, and heating element are located within the base. A connecting post is provided on the top surface of the plastic mounting base, and the heating element is mounted on the connecting post. Multiple connecting seats are provided around the bottom perimeter of the plastic mounting base, with connecting holes at the top of each connecting seat. A positioning hole is provided within each connecting seat, with its lower end open and its upper end communicating with the connecting hole. The top of the mounting base has a fan mounting hole, and the fan is installed in the fan mounting hole. The top of the plastic mounting base has an upward-protruding upper air guide plate around the fan mounting hole. The circuit board is located on the top surface of the plastic mounting base. The upper air guide plate is open on the side facing the circuit board. Multiple positioning nut seats are provided on the base corresponding to multiple connecting seats. The positioning nut seats have screw holes. The plastic mounting base sits on the base, and the bottom of the plastic mounting base is open. The positioning nut seats extend upward into the positioning holes and are positioned and engaged with the positioning holes. The screws pass downward through the connecting holes and positioning holes in sequence, and then are threaded into the screw holes. This utility model isolates the heating device, circuit board, and base through the plastic mounting base, thus achieving insulation. Moreover, the plastic mounting base and cooling fan have good heat dissipation performance, and the operation of the circuit board is not affected by the heating device. The plastic mounting base is locked onto the base with screws, making disassembly and assembly very convenient.

[0005] The present invention can be further improved in the following ways.

[0006] A ring-shaped lower air guide plate extends downward from the bottom of the fan mounting hole. The lower air guide plate separates the inner cavity of the plastic mounting base from the fan mounting hole. The base has an air inlet corresponding to the position of the lower air guide plate, which makes the airflow more concentrated, the airflow larger, the airflow faster, and the heat dissipation effect of the circuit board better.

[0007] The plastic mounting base, connecting column, upper air guide plate, lower air guide plate, and multiple connecting seats are integrally molded. The structure of the plastic mounting base of this utility model is reasonable and easy to manufacture.

[0008] This utility model also includes bolts and washers. The heating device is provided with connecting feet around its perimeter. The connecting feet are L-shaped and have through holes at their lower ends. The lower ends of the connecting feet are fitted onto the connecting posts. A spring is fitted onto the connecting posts. The upper and lower ends of the spring abut against the connecting feet and the connecting posts, respectively. The connecting posts have internal threaded holes. The bolt's shank passes downward through the washer and the lower end of the connecting feet in sequence and is threaded into the internal threaded hole. The washer is located between the head of the bolt and the lower end of the connecting feet.

[0009] The outer wall of the connecting column is equipped with reinforcing ribs.

[0010] The inner top and inner side walls of the plastic mounting base are reinforced with ribs, which makes the plastic mounting base strong.

[0011] The top surface of the plastic mounting base has multiple screw holes for mounting circuit boards.

[0012] The shape of the positioning nut seat matches the shape of the positioning hole, making it easy for workers to quickly position the plastic mounting base on the base.

[0013] The bottom of the base has heat dissipation holes corresponding to the inner cavity of the plastic mounting base, which makes the plastic mounting base dissipate heat quickly and efficiently.

[0014] The beneficial effects of this utility model are as follows: This invention isolates the heating element, circuit board, and base using a plastic mounting base, thus achieving insulation. Furthermore, the plastic mounting base and cooling fan have good heat dissipation performance, ensuring that the circuit board's operation is not affected by the heating element. Additionally, the plastic mounting base is secured to the base with screws, making disassembly, repair, and replacement very convenient. If one of the burner modules malfunctions and requires repair, it can be easily replaced by removing the screws. Attached Figure Description
