Description
Technical field
The utility model relates to electric heater technical field, more particularly, relates to a kind of electric heater with A shape water inlet pipe.
Background technology
Along with the raising of people's living standard, water heater particularly electric heater also more and more spreads to ordinary family, people are to the use of water heater also bathing function just not, but also can on other domestic water, use, and wash one's hands etc. and to need the occasion of hot water as washed dish winter.For the discriminating of the performance of water heater, hot water delivery rate is an important index.Water heater hot-water output rating refers to the ratio of actual hot water output quantity and rated capacity under rated condition, and it has reflected the degree of power conservation of water heaters design, and many good tries have been made for this reason by many water heaters manufacturer.The water inlet structure design of water heater is to determine one of key point of hot water delivery rate, water inlet pipe design all requires that Water discharge flow speed is low, water outlet direction as far as possible downwards, to reduce hot and cold water heat transfer intensity.It is 201010236348.2 1 kinds of Chinese invention patent applications that can improve the electric heater of hot water delivery rate that on December 1st, 2010 discloses number of patent application, the water part of the water inlet pipe of this water heater is provided with apopore, and be mounted with current bufferings net in the water part of water inlet pipe, this buffering net is on water inlet pipe or be placed in water inlet pipe, and with the corresponding setting of apopore of water inlet pipe.The water inlet pipe of this water heater adopts sleeve design, attempt the mode coordinating with water inlet pipe apopore by buffering net, increase the resistance of water inlet inflow inner bag, thereby reduce the water velocity of water inlet, when entering inner bag, minimizing cold water for the impact of upper strata hot water, improves the hot water delivery rate of water heater.But this heater inleting pipe's apopore cross section is less and horizontally outward, though buffering net can appropriateness reduce water outlet water velocity, but because the perforate aperture of buffering net is little, limited amount, and perforate can only be at the root position of water inlet pipe, thereby when current are from the perforate of buffering net out time, its flow velocity is still higher, still the water body of inner bag is caused to certain degree of disturbing, second, the perforate of buffering net is easily stopped up by incrustation scale and insoluble foreign matter, make water outlet of water heater not smoothly, when serious, need maintain and replace inlet pipe casting, bring many troubles to user and after-sale service.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of a kind of electric heater with A shape water inlet pipe that can significantly slow down water inlet pipe Water discharge flow speed is provided, definite effectively raising hot water delivery rate of electric water heater, make not only energy-conserving and environment-protective but also can fully meet and use needs of water heater, reduce Energy in use, for user brings material benefit.
Utility model object of the present utility model is achieved in that a kind of electric heater with A shape water inlet pipe, comprise inner tube and outer tube sleeve, inner tube is inserted in the inner bag of electric heater, outer tube sleeve is overlapped on inner pipe, outer wall of inner tube is provided with some circumferential ribs, the external profile diameter of circumferential rib and the internal diameter of outer tube sleeve are suitable, on each circumferential rib, are provided with water-flowing trough, and the bottom opening of outer tube sleeve and outer wall of inner tube form annular delivery port.
Preferably, also comprise plug, described plug makes outer tube sleeve top closure, is provided with the interior tube opening under oblique on the top of inner tube.
Preferably, the water-flowing trough on adjacent circumferential rib staggers mutually.
Preferably, be separated by 180 ° two water-flowing troughs are set on every circumferential rib, the water-flowing trough on adjacent circumferential rib staggers mutually 90 °.
Preferably, the lower end tube wall of described outer tube sleeve arranges some layers of apopore, changes from small to big from top to bottom in the aperture of described apopore.
The beneficial effects of the utility model are:
1) water inlet pipe of the present utility model comprises inner tube and outer tube sleeve, the top closure state of inner tube and near open the delivery port under oblique at the epimere of inner tube, inner tube pipe outer wall is evenly equipped with circumferential rib, has water-flowing trough on rib, the circumferential rib close contact of the inwall of outer tube sleeve and inner tube.This structure make from inner tube delivery port water body out must in the local space that the circumferential rib of every one deck and two sleeve pipe tube walls form, remain in a standstill, again the water-flowing trough through rib flow under the circumferential rib Intercostal Space of one deck, make first water outlet current collide after inside and outside tube wall, circumferential rib again baffling to water flowing notch, consume the kinetic energy of a large amount of current, thereby reduce delivery port water velocity out, reduce to the utmost the water disturbance of water inlet to liner for water tank of water heater, the harmful effect of effectively avoiding water disturbance to cause, thus higher hot water delivery rate ensured.
2) outer tube sleeve of water inlet pipe has away from inner tube water outlet the apopore that aperture increases gradually from top to bottom, main water outlet current enter inner bag from the ring exit of outer tube sleeve bottom, main delivery port from hot water layer farthest, make main current minimum to the hot water disturbance on upper strata, inner bag inside, sub-fraction water body divides and flows to inner bag from the very little apopore in aperture, top, from the bottom of outer tube sleeve, larger apopore flows out the water body of a part, this design can make water velocity slowly slow down in outer tube sleeve, guarantee that most of water body enters into inner bag inside with minimum disturbance velocity, improve water heater hot-water output rating.
Brief description of the drawings
