Seeking : Integrateable solution for electrical household appliances enabling gas venting, and at the same time water tightness

Desired outcome

We are searching for a solution for electrical household appliances which provides both pressure equalization between in- and outside and prevents water to enter the appliance.

The Procter & Gamble Company

Details of the Innovation Need

We need a solution that can be integrated into a plastic enclosure and provides the following characteristics:

  • Permeability to gas (air) in both directions for pressure equalization between inside of enclosure and environment
  • Water-tightness to prevent water from entering the enclosure
  • The aforementioned properties must be sustained over a prolonged period (several years), even if the enclosure is regularly exposed to water and specific substances such as toothpaste, rinse, cleaning agents and others.
  • Solutions might be but not limited to venting membranes, valves, etc.

In Scope Details:

Water tightness: IPX7, IPX8

Gas permeability (air):

  • Gas permeability (air) must be at least 2.0 l/h at a differential pressure of 150 mbar
  • The orifice at the enclosure shall be as small as possible but not exceeding 15 mm².
  • The solution shall not get damaged with an instantaneous differential air pressure of 3 bar.

These required functionalities must be provided under the following conditions:

  • The requirements must also be fulfilled even after a period of five to seven years of use.
  • Temperature storage range between -20 °C and 80 °C
  • The solution must be compliant with regulations for household electrical devices.
  • The enclosure can be exposed to water and personal care products (e.g. toothpaste, rinse, shaving foam) and cleaning agents (detergents, isopropanol, ethanol, disinfection agents) on a daily basis.
