How can the waterproof and anti-leakage technology of electromagnetic heating furnace adapt to the humid environment of the kitchen?
Release Time : 2025-04-17
Kitchens are high-frequency water-using areas, and humid environments are prone to short circuits, leakage and other safety hazards in electromagnetic heating furnaces. Therefore, waterproof and leakage-proof technology has become a key technology for electromagnetic heating furnaces to adapt to kitchen environments. Only through advanced waterproof and leakage-proof design can electromagnetic heating furnaces be ensured to operate stably in humid environments, ensuring the personal safety of users and the service life of equipment.
Electromagnetic heating furnaces use high-performance waterproof sealing materials to build the first protective barrier. Food-grade silicone sealing rings are widely used in the joints between the furnace body and the control panel, furnace door, etc. They have good flexibility and aging resistance, can tightly fill gaps, and effectively prevent moisture from penetrating. For example, a U-shaped silicone sealing ring is embedded in the edge of the furnace door to form a complete sealing structure when the furnace door is closed, and even under strong steam or splashing water impact, the internal circuit can be ensured to be unaffected. In addition, insulating waterproof glue is also commonly used to seal key parts such as circuit boards and terminal blocks. After curing, this glue forms a tough waterproof film, which completely isolates electronic components from the external humid environment to prevent moisture erosion and leakage risks.
Reasonable waterproof structure design further enhances the waterproof ability of electromagnetic heating furnace. Its shell mostly adopts integrated molding process to reduce the joint gap and reduce the water penetration path. At the same time, the bottom of the equipment is usually designed as a slope or groove structure, so that the water that accidentally enters can be quickly discharged to avoid the damage of internal components caused by accumulated water. For example, some electromagnetic heating furnaces adopt a double-layer waterproof flange design at the seam of the shell. The outer flange blocks splashing water droplets, and the inner flange prevents the infiltrated water from entering the core area. The double protection significantly improves the waterproof performance. In addition, the vents, heat dissipation holes and other parts are also equipped with waterproof shutters or waterproof breathable membranes, which can not only ensure the normal heat dissipation of the equipment, but also prevent water vapor from intrusion.
The electromagnetic heating furnace has a built-in precise leakage protection circuit to monitor the current changes in the circuit in real time. Once a leakage is detected, such as abnormal current fluctuations or leakage current, the leakage protection device will quickly cut off the power supply within 0.1 seconds to avoid electric shock accidents. At the same time, a reliable grounding system is also an important guarantee for preventing leakage. The equipment introduces the possible leakage current into the earth through a dedicated grounding wire to reduce the risk of human contact with live parts. For example, in some high-end electromagnetic heating furnaces, a dual leakage protection mechanism is adopted. In addition to the conventional leakage circuit breaker, a residual current action protection device is also added to further improve the sensitivity and reliability of leakage protection.
The circuit board is the core component of the electromagnetic heating furnace, and it is very important to treat it with waterproof and moisture-proof treatment. Using nano-coating technology, an ultra-thin waterproof film is formed on the surface of the circuit board. The film is hydrophobic and can effectively prevent water and moisture from contacting the circuit components, while not affecting the normal heat dissipation and electrical performance of the circuit board. In addition, the potting process is also commonly used for circuit board protection. The insulating potting glue is filled into the gaps of the circuit board and the surface of the components. After curing, a sealed protective layer is formed to isolate the external moisture and dust, and improve the stability of the circuit board in a humid environment. Some manufacturers will also perform three-proof treatment (moisture-proof, mildew-proof, and salt spray-proof) on the circuit board to further enhance its adaptability in harsh environments.
To ensure the effectiveness of the waterproof and leakage-proof process, strict testing and quality control in the production process are indispensable. Electromagnetic heating furnace needs to pass multiple waterproof performance tests such as water spraying test and immersion test. The water spraying test simulates the daily splashing scene in the kitchen, sprays water to the equipment at a specific angle and flow rate, and observes whether there are water stains inside; the immersion test immerses the equipment in water of a certain depth to detect its waterproof sealing. At the same time, the leakage protection function is repeatedly tested, and the response speed and reliability of the leakage protection device are verified by simulating leakage conditions. Only products that pass all tests can enter the market, ensuring the safety of products in the humid environment of the kitchen from the source.
Electromagnetic heating furnace builds a comprehensive waterproof and leakage-proof system through high-performance waterproof sealing materials, optimized waterproof structure design, leakage protection circuit and grounding system, waterproof and moisture-proof circuit board processing technology and strict testing and monitoring. The comprehensive application of these processes and technologies enables it to effectively adapt to the humid environment of the kitchen, which not only ensures the safety of users, but also improves the reliability and service life of the equipment, providing users with a safe and stable cooking experience.
