The invention discloses a water inlet device. The water inlet device comprises a base with a water inlet and a casing pipe with a water inlet hole and a water outlet hole, wherein the water inlet holeis in tight coupling with a water outlet and communicates with the water outlet hole through a water inlet passage; the water inlet passage is located in the casing pipe, extends in the axial direction of the casing pipe, and has at least two inflexions in the casing pipe; and the base and the casing pipe are insulation components. The invention also discloses a water heater with the water inletdevice. When water enters from the water inlet, flows through the water inlet passage and finally flows out of the water outlet hole, the water passes the at least two inflexions in the casing pipe along the water inlet passage, which is equivalent to the prolonging of the water flow path, and increases the length of water resistance, thus, the electric prevention effect is improved, and the prolonged water flow path is limited in the casing pipe; and the water inlet device has a small and compact overall structure and is convenient for matching with various water heaters. The water inlet device can be applied to occasions where the water resistance is used for preventing electric shock.
Description
technical field [0001] The invention relates to the field of water heaters, in particular to a water inlet device and a water heater equipped with the water inlet device. Background technique [0002] Some water heaters on the market now have a water inlet device that uses water resistance to limit the size of the leakage current at the water inlet position, so that the current leaked from the water inlet meets the requirements of human body safety standards. However, these water inlet devices are greatly affected by the length of the pipeline, and the anti-shock effect is also different. In particular, some products such as electric partition walls and anti-shock walls on the market are greatly limited by size. Contents of the invention [0003] The purpose of the present invention is to provide a water inlet device. [0004] The invention also provides a water heater. [0005] The technical solution adopted for solving the above-mentioned technical problems: [0006] ...
