2results about How to "Solve the noise problem" patented technology

This utility model discloses a low-noise water heater, comprising: a heating element disposed at the bottom of a cavity; the heating element includes a heating tube and a heat spreader plate, the heating tube and the heat spreader plate being thermally connected, the heat spreader plate being attached to the bottom of the cavity, and the heating tube being spirally arranged; the ratio of the thickness of the heat spreader plate to the surface load of the heating tube is greater than or equal to 40%, and the thickness of the heat spreader plate is 3.5-5mm; wherein, the effective heat transfer area ratio of the heating tube and the heat spreader plate is greater than or equal to 50%, and the heating tube and the heat spreader plate cooperate to homogenize the heat generated by the heating tube; a first through hole is provided on the lower surface of the cavity, and a water inlet pipe passes through the spiral gap of the heating tube and the first through hole in sequence; a bracket is provided on the inner surface of the cavity, the bracket being disposed on the first through hole, and the bracket being used to buffer the water flow of the water inlet pipe. This device fundamentally solves the noise problem caused by uneven heating and bubble bursting during the heating process.

This invention discloses an air conditioner for use in the home appliance industry, comprising: an energy storage device for containing energy storage material; a jet driving device assembled in the energy storage device; and a flow distribution device connected to the energy storage device via the jet driving device. When the jet driving device acts on the energy storage device, the energy storage device jets the energy storage material into the flow distribution device, and the jetted energy storage material is dispersed and emitted in the flow distribution device to release heat or cold energy. This invention solves the noise problem of air conditioners.
