Description

TECHNICAL FIELD

[0001] The utility model relates to control panel technical field especially disclose a kind of nanometer waterproof control panel for household appliance product. BACKGROUND

[0002] Household appliance is widely used in people's daily life, and its control panel, as a core component, is responsible for the transmission of circuit signals and the realization of device functions. However, household appliances often face adverse environments such as high humidity, splashing water, dust and chemical corrosion during actual use, which poses a serious threat to the service life and stability of the control panel. Therefore, effective waterproofing, dustproofing and corrosion protection of the control panel has become an important technical issue in the design of household appliances.

[0003] In the prior art, a protective layer is usually formed on the surface of the control panel by dripping or spraying glue to improve its protective performance. However, these techniques have obvious limitations. The protective layer formed by dripping or spraying glue is thick (usually millimeters) and has high density, which significantly increases the overall weight of the control panel and makes it difficult to meet the lightweight and portable design requirements of household appliances. At the same time, when covering the surface of the control panel, traditional processes are prone to blind spots or uneven coating thickness, resulting in poor local protection effect and inability to completely isolate the invasion of moisture, dust or corrosive substances. SUMMARY

[0004] To overcome the shortcomings and deficiencies in the prior art, the purpose of the present utility model is to provide a nanometer waterproof control panel with good waterproof performance and light overall weight.

[0005] To achieve the above-mentioned purpose, the utility model provides a nanometer waterproof control panel for household appliance product, which comprises a control panel body, a panel provided on the control panel body, a control assembly electrically connected to the control panel body provided on the panel, and a nanometer protective film provided on the surface of the control panel body to form a continuous protective layer on the surface of the control panel body. The control panel body comprises a circuit board and a chip body provided on the circuit board, and an electrode wire is provided on the chip body. The chip body is electrically connected to the circuit board via the electrode wire. The chip body comprises a rectifier, a capacitor, a voltage stabilizer and a controller.

Through reasonable thickness design, efficient protection is achieved to meet the needs of lightweight and stable performance of household appliances.

[0010] Further, the nano protective film is plated on the control panel body by electroplating, vacuum plating or vapor deposition. The process is efficient and suitable for large-scale production, the coating uniformity is high, the coverage blind area is reduced, the production cost is reduced, the coating adhesion and coverage precision are improved, and the protection performance is ensured.

[0011] Further, the nano protective film comprises a nano waterproof layer and a corrosion-resistant layer, and the corrosion-resistant layer is located between the nano waterproof layer and the control panel body.
