Abstract
The utility model discloses an electric water heater with a manger at a water inlet. The electric water heater comprises a liner, an electrical heated pipe, a water inlet pipe and a water outlet pipe, wherein the manger is covered at an outlet of the water inlet pipe at the bottom of the liner of the water heater, and water diversion channels are arranged on the manger. The manger is installed at the bottom of the liner of the electric water heater, so that the water outlet of the water inlet pipe in the liner is arranged under the manger. A certain amount of diversion channels are distributed on the manger, so that the open area is increased, the flow velocity of water entering the electric water heater is reduced, and the pressure is reduced. Meanwhile, a distributary channel is formed by adjusting the opening direction of diversion holes and increasing water retaining ribs, so that water flow distribution is more uniform, the water flow rebound or disturbance stratification caused by water flow impacting the inner wall of the liner is reduced or avoided, further the hot water output efficiency is increased, and energy sources are saved.
Description
Technical field
The utility model relates to field of water heaters, relates in particular to the electric heater that a kind of water inlet is equipped with water fender.
Background technology
Existing electric heater generally comprises inner bag, water inlet pipe, outlet pipe, magnesium rod and electrothermal tube, and water inlet pipe has apopore in the bottom, and the outlet pipe opening is driveed on top, and cold water gets into inner bag from the apopore of water inlet pipe, after the electrothermal tube heating, discharges from outlet pipe.
At present on the water inlet scheme of the inherent inner bag of water heater industry, what generally adopt is directly perforate on the water inlet pipe tube wall, groove, the apopore on the water inlet pipe by certain regular distribution around pipe; The quantity in hole has from several to dozens of, and when inner bag was intake, the scope of water inlet was all in water inlet pipe has the scope of apopore place circumference from water inlet pipe; Because the diameter of water inlet pipe generally has only about 20mm; Restricted by this, the delivery port diameter on the water inlet pipe is less, and the current distribution is also less; Under the situation that big discharge occurs; Such as 10L/min, big water flow velocity then can appear, and because the direction of current is distributed in the water pipe circumferencial direction; From the near position of inner bag inwall; Can cause the current bounce-back, destroy the hot and cold water layering to a certain extent, can not effectively upper strata hot water be extruded.
Water heater is in the following time of duty of heating, because the density of the water that density is little, temperature is low of the high water of temperature is big, can form the layering of hot water and cold water.If this moment, the user opened the flowing water Valve of water heater, cold water will get into inner bag from the water inlet pipe apopore, pushes hot water simultaneously and flows out from outlet pipe; Cold water discharge is big more, and cold water is just big more from the strength that the water inlet pipe apopore impacts the inner bag inwall, and cold water is directly just many more to the upper part of water heater liner by rebounce; Disturbance to water body is just big more; So the layering of whole inner bag the inside hot and cold water will be destroyed, inner bag top water temperature can descend, and hot water is effectively utilized.
Chinese patent document (publication number CN 101153746A) discloses a kind of water heater that can alleviate the water inlet impulsive force, make the water inlet insulation tube of inner bag location that has; Said water inlet insulation tube comprises to be located at the outer water inlet pipe of water heater liner, to be located at the interior pipe that is communicated with water inlet pipe in the inner bag and to be sheathed on the outside sleeve pipe of interior pipe; Be connected through the spiral shell head between water inlet pipe and the interior pipe; Form the space between interior pipe and the sleeve pipe; The sleeve pipe perisporium is provided with the distributing apopore, and the space between sleeve pipe lower end and the interior pipe is provided with positioning boss, both can reinforce sleeve pipe; Also can block into water to the impact of inner bag inwall, water inlet can get into inner bag from the distributing apopore after impulsive force is alleviated in the space like this.The impact of the current of water inlet pipe to the inner bag inwall alleviated in this invention through the mode that sleeve pipe and positioning boss are set; Avoided destruction to the hot and cold water layering; But this technical scheme cost is higher, need design production again to water inlet pipe, simultaneously because cold water is to cushion in water inlet insulation tube inside; Limited because of the inner space, can not satisfy the requirement that cold water injects fast.
