In the home appliance industry, the waterproof performance of products directly affects user safety, product lifespan, and brand reputation. As a testing device that simulates natural rainfall environments, the swing tube rain test chamber (such as Hengtai Fengke)BLThe series provides precise control of water flow pressure, angle, and coverage range for household appliancesIPProtection level verification provides scientific basis. Starting from technical characteristics, application scenarios in the home appliance industry, and typical cases, this article analyzes its core value in ensuring product quality.

1、 Technical feature: high-precision simulation of natural rainfall environment

Hanging tube rain test chamber (toBL-12Taking the model as an example, multi angle rain testing is achieved through swinging the pendulum tube, rotating the worktable, and a water circulation system. Its core advantages are reflected in:

Flexible swing tube design: providingBL-04toBL-12Five models, with swing tube radius coverage0.4mto1.2mIt can be adapted to different sizes of household appliances (such as small lamps, large air conditioning outdoor units).

Accurate water flow control: Rainwater pressure can be controlled within80～100kPaAdjustment within the range, nozzle aperture and swing angle（±45°to±180°）It can be customized to simulate various scenes from drizzle to rainstorm.

High reliability material: The swing pipe bracket, water storage tank, and control console are made ofSUS304Stainless steel hairline plate, with strong corrosion resistance, suitable for humid testing environments.

Intelligent Control System: ThroughPLCAutomated control of swing tube oscillation and worktable rotation with stepper motor, supporting stepless speed regulation and multi angle spraying, ensuring the repeatability and accuracy of test results.

2、 Application scenarios in the home appliance industry: Quality control throughout research and development and production

Product waterproof grade verification

IPX1toIPX6Testing: According toGB 4208—93Standard, simulate scenarios such as vertical dripping, inclined rain, and strong water spraying to verify the sealing and drainage capabilities of household appliance casings. For example, a certain brand's outdoor camera needs to pass throughIPX6Level testing, testing chamber100L/minThe water flow continues to spray3Minutes, ensure that there is no water ingress into the internal circuit.

Customized testing plan: For special application scenarios (such as pool cleaning robots), non-standard swing pipe radius and spray angle can be designed to simulate underwater working environments.

Reliability testing during the R&D phase

Design defect exposure: In the early stage of product development, problems such as weak adhesion of sealing strips and unreasonable design of drainage holes were found through rain tests on the swing tube, avoiding the risk of recall after mass production. For example, during testing, a certain smart speaker found that the bottom drainage hole was prone to water accumulation, causing corrosion of the circuit board. After optimization, it passedIPX4Level testing.

Assessment of material weather resistance: Testing the fading and deformation of different shell materials (such as plastic and metal) after long-term exposure to rain, providing a basis for material selection.

Sampling and certification during the production stage

Mass production quality control: Randomly select finished products from the production line for rain testing to ensure consistent waterproof performance for each batch of products. For example, a certain air conditioning manufacturer requires every100Sampling inspection of outdoor machines1The platform is in progressIPX5Testing, the pass rate needs to reach100%.

International certification support: Test box test data can be directly used forCETheULWaiting for international certification to assist in product exports.

3、 Typical case: Technology empowers the upgrading of home appliance quality

A certain household appliance brand: validated its new washing machine through a rain test box with a swinging tubeIPX4The waterproof performance under the level was found to have design defects in the sealing gasket of the control panel, which caused water droplets to seep in. After optimization, the product passed the test smoothly and the market complaint rate decreased30%.

A certain intelligent lighting enterprise: targeting outdoor courtyard lightsIPX6During the level test, it was found that there was a gap at the connection between the lampshade and the lamp body, causing water to enter the interior. By improving the sealing structure, the product ultimately passed testing and successfully entered the European market.

An automotive electronics supplier: use the test box to simulate the working state of the on-board camera in rainstorm, and verify itsIPX9KLevel protection capability ensures the reliability of the product in extreme weather conditions.

4、 Future trend: Integration of intelligence and environmental protection

With the increasing demand for product quality and energy efficiency in the home appliance industry, the swing tube rain test chamber is developing in the following directions:

Intelligent upgrade: integrating IoT technology to achieve remote monitoring, automatic data collection and analysis, such as throughAIAlgorithm identifies the location of water ingress in the product and optimizes the testing process.

Environmentally friendly design: adopting a water circulation system and water-saving nozzles to reduce testing water consumption and meet the needs of green manufacturing.

Multi functional integration: Combining salt spray, high temperature and humidity environment testing, simulating complex usage scenarios, and improving testing efficiency.

Conclusion

As a core tool for verifying waterproof performance in the home appliance industry, the swing tube rain test chamber's technological progress directly promotes the improvement of product quality and the enhancement of market competitiveness. Faced with the dual demands of innovation and compliance in the industry, the intelligent and environmentally friendly upgrading of test chambers will become the key to future competition. For home appliance companies, choosing a testing chamber supplier with comprehensive technology and services is not only a necessary measure to ensure product quality, but also an important strategic choice to enhance brand reputation and expand international markets.
