Abstract

The utility model discloses a water heater with an intake shock absorbing device and solves the problems of influencing the use of the water heaters, leading to energy waste and so on due to that cold water and hot water is easy to mix in the current water heaters. The utility model has the advantages of simple structure, convenient use, avoiding harmful blending of cold water and hot water efficiently, improving the utilization rate of hot water and reducing energy loss. The utility model is characterized in that the water heater has a water tank in which a hot water discharge pipe is arranged, at least one T-type intake shock absorbing device which consists of at least one cross tube and at least one standpipe is also arranged on the lower part of the water tank, wherein the two ends of the cross tube are sealed and plugged, and are installed along the axial direction of the water tank, the end of the standpipe extends out of the water tank and injects cold water, and a plurality of pores are arranged below the cross tube.

Description

Bring the water heater of water buffer unit into

Technical field

The utility model relates to a kind of water heater, relates in particular to a kind of water heater of bringing the water buffer unit into.

Background technology

Bearing hot water device in the market all adopts top ability of swimming water outlet, and promptly cold water enters from the water heater bottom during water, and the hot and cold density official post water of water forms layering, and the hot water in the water heater is ejected by the cold water that the bottom enters, as shown in Figure 1.

Because water heater is a bearing operation, water inlet has pressure (hydraulic pressure of running water), causes hot water or cold water's rapid mixing easily.For realizing hot water or cold water's layering, the water inlet pipe place need design the water (flow) direction that the water inlet buffer unit changes water inlet, directly rushes at tank top to prevent cold water (running water).Common in the market water inlet buffer unit has following several structure, i.e. the circumference punched holes type of Fig. 2, the U type baffle-type of Fig. 3, the V-baffle formula of Fig. 4, the umbrella-shaped baffle formula of Fig. 5, the pipe back reverse-flow type of Fig. 6.

More than all water inlet buffer unit version all exist the hot water effluent to lead low drawback, because though above equipment has changed the water inlet direction of cold water, but in cold water enters and concentrates on very among a small circle behind the water tank, under the tap water pressure effect, still exist bigger cold, the hot water mixing phenomena, particularly the hot water at water tank two ends have little time to be ejected and and cold water mix, the hot water effluent of above by experiment water inlet buffer unit version leads and depresses at normal running water only is about 70%, do not reach the temperature requirement of bath water after all the other about 30% hot water and the cold water mix, heat the required electric energy of this part hot water and wasted.

Summary of the invention

The purpose of this utility model is easily mixed in order to solve present water heater hot and cold water exactly, influence its use, and cause problems such as energy waste, provide a kind of have simple in structure, easy to use, can effectively avoid the unhelpful mixing of hot and cold water, improve the utilization rate of hot water, reduce the water heater of bringing the water buffer unit into of advantages such as energy consumption.

For achieving the above object, the utility model adopts following technical scheme:

A kind of water heater of bringing the water buffer unit into, it has water tank, be provided with hot water out pipe in it, the bottom of described water tank also is provided with at least one T type water inlet buffer unit of being made up of at least one transverse tube and at least one vertical tube, the wherein two ends shutoff of transverse tube, and along the installation of water tank axis direction, the vertical tube end stretches out water tank input cold water, is provided with several apertures below transverse tube.

Described aperture is tubaeform, and is spacedly distributed.

The inner bag ladle body of described transverse tube and water tank is isometric, the interior bottom 15-20mm of transverse tube distance from bottom inner water tank.

All aperture flow sums of described transverse tube are greater than the flow of vertical tube.

The utility model is formed the T type by vertical tube and long transverse tube, the shutoff of transverse tube two ends, and several tubaeform apertures are set bottom the transverse tube, transverse tube is placed along the inner water tank axis direction, apart from the interior bottom 15-20mm of inner water tank.Its operation principle is: cold water is shunted to the transverse tube direction of both ends when vertical tube enters into the junction of horizontal, vertical pipe, cold water enters water tank bottom downwards through toy trumpet shape hole again, the water inlet buffer unit of this version is evenly distributed on water tank bottom after making cold water enter water tank, promptly whole inner bag length direction; Because the flow sum of all apertures is greater than the flow of vertical tube, the layering of cold water and hot water is very obvious.Like this along with cold water continuously enters water tank, the cold water of water tank bottom is with the upwards top of the hot water uniform and stable in the whole water tank, hot water on the whole length direction of water tank is all up pushed up, hot water or cold water's mixing phenomena can not occur, what the hot water outlet pipe was flowed out is the high-temperature-hot-water of water tank upper all the time.The hot water effluent of the water inlet buffer unit through testing this T type structure leads and reaches more than 90%, the hot water effluent who has improved water heater greatly leads, equal water temperature is set uses more hot water, with hot water lower water temperature can be set, be actually and improved the water heater energy-efficient performance greatly with amount.
