Description

[Technical field]

[0001] The present invention relates to the technical field of household products, in particular to a noise-reducing dry instant tap. [Background technology]

[0002] Faucets are used to control the amount of water flow and start and stop. Faucets have been updated very quickly, evolving from the old cast iron process to electroplated knob type, stainless steel single temperature single control faucets, stainless steel dual temperature dual control faucets, kitchen semi-automatic faucets, instant faucets, etc. However, these faucets on the market do not have the exhaust and drying function, and if the exhaust and drying function is required, a separate device is used, which occupies a large space and is expensive to use, so faucets with drying function have appeared.

[0003] For example, the multifunction sensing faucet structure disclosed in Chinese patent document CN214248446U includes a casing and a water discharge component, the casing includes a vertical section and a horizontal section, and an installation channel is provided in the casing, the water discharge component includes a nozzle, a water discharge pipe, a solenoid valve and a first detection switch, the nozzle is provided with a water discharge outlet communicating with the installation channel, the water discharge pipe is provided in the installation channel, one end of the water discharge pipe is screwed connected to the water discharge outlet and the other end is connected to the solenoid valve, the detection switch is connected to the control solenoid valve, an air exhaust channel is provided in the casing, the nozzle is provided with an air exhaust outlet corresponding to and communicating with the outlet of the air exhaust channel, the inlet of the air exhaust channel is connected to a rear installation groove, and an air exhaust drying module is provided in the rear installation groove.

[0004] In this structure, the exhaust channel is too long, the exhaust channel is close to the water discharge pipe, and the heating component is far from the exhaust port, so the hot air needs to pass through the entire exhaust channel when discharging. During water discharge, the temperature of the exhaust channel is likely to decrease, the heat of the hot air dissipates a lot, and the thermal utilization rate of the entire faucet is low.
