Abstract

Provided is a multistage water tank of a solar water heater. The position between an outer shell of the water tank and an inner container is filled with heat preservation materials, a water inlet pipe is arranged at the front end of the water tank, a water outlet pipe is arranged at the rear end of the water tank, the inner container in the outer shell is composed of a plurality of inner container units in a series connecting mode, the position between every two inner container units is filled with the heat preservation materials, and every two inner container units are communicated through a communication pipe. The water inlet of each communication pipe is located in the upper portion of the inner container unit of the upper stage, the water outlet of each communication pipe is located in the lower portion of the inner container unit of the lower stage, and an exhaust pipe is arranged on each inner container unit; a drain pipe is arranged under each inner container unit, and an auxiliary heating device is arranged on the lower portion of the inner container unit of the last stage. Due to the fact that the heat preservation materials are used for separating every two inner container units, heat exchange between the inner container units is greatly reduced; cold water in the inner container unit of the upper stage is led to the bottom layer of the inner container unit of the lower stage through the communication pipes, so that hot water on the upper layer in the inner container unit of the lower stage is prevented from being disturbed by the introduced cold water, and the problem that temperature is reduced too fast is solved; due to the fact that each inner container unit is provided with the exhaust pipe, the air blocking phenomenon in the inner container is avoided.

Description

The multistage water tank of solar water heater

Technical field

The utility model belongs to technical field of solar water heaters, relates to the multistage water tank of a kind of solar water heater.

Background technology

Solar water heater is roughly divided into two classes, and a class is electron tubes type, and another kind of is accessory pinna formula, and the heat collector of two class solar water heaters is connected on a water tank.In prior art, water tank is comprised of a shell and an inner bag mostly, and because the volume of inner bag is larger, in use, in inner bag, once exhaustless hot water is understood rapid mixing with the cold water newly filling in inner bag, causes hot water temperature's fast-descending in inner bag; In addition, run into the continuous cloudy day, in solar water heater, there is no hot water, need to use external heater to heat the cold water in inner water tank, heater will heat the water in whole inner bag, the energy requirement consumption of heating institute is larger, time used is longer, and as a rule, the hot water amount who need to use is much smaller than the hot water amount after heating, unnecessary hot water is mixed cold in vain in water tank, causes heat energy to waste.

For addressing the above problem, people have invented a kind of water tank of duplex inner bag, two parts before and after this water tank is divided into inner bag with one deck partition panel, the top of two inner bags is communicated with a through hole, an inner bag after cold water is entered by through hole after being full of previous inner bag again, this technology has solved some problems that exist in single inner bag water tank well, but, in actual use, between two inner bags due to this water tank, only use the isolation of one deck stainless steel separator, when cold water enters previous inner bag, the speed that heat exchanges through dividing plate is still very fast, hot water temperature in a rear inner bag declines still very fast, in addition, because the top of this water tank at two inner bags is communicated with, solar water heater generally adopts upper hot water of water tank first to discharge the design of use, hot water in previous water tank is finished, cold water in previous water tank enters the upper strata of hot water in a rear inner bag from through hole, hot water disturbance to layering in a rear inner bag is larger, causes the upper strata hot water temperature of a rear inner bag to decline too fast, makes the time advance of cold water output in outlet pipe.

Summary of the invention

In prior art, adopt the solar water heater water tank of duplex inner bag design to exist the hot and cold water in the inner bag of front and back through dividing plate, to carry out the problem of the speed of exchange heat, and two inner bags are communicated with from top, exist cold water in last inner bag directly to sneak in the upper strata hot water of a rear inner bag, after causing, in an inner bag, the disturbance of layering hot water is larger, the problem of output cold water time advance, the utility model provides a kind of solar water heater multistage water tank, between the shell of water tank and inner bag, be filled with insulation material, the front end of water tank is equipped with water inlet pipe, outlet pipe is equipped with in rear end, inner bag in shell is composed in series by a plurality of, between two inner bags, be filled with insulation material, between two inner bags with being communicated with communicating pipe, the water inlet of communicating pipe is positioned at the top of previous stage inner bag, delivery port is positioned at the middle and lower part of rear one-level inner bag, above each inner bag, be separately installed with a blast pipe.

Each inner bag below in the enclosure, is all provided with a blow-off pipe.

Assisted heating device is arranged on the below of water tank rear end outlet pipe, and assisted heating device stretches into the inside of afterbody inner bag.

Adopt technical solutions of the utility model, owing to two inner bags being separated with insulation material, the heat exchange between inner bag reduces greatly; Due to the bottom of an inner bag after cold water in last inner bag being introduced with communicating pipe, the cold water disturbance of having avoided the upper strata hot water in a rear inner bag to be entered, has solved the temperature too fast problem that declines; Due to inner bag is carried out to plural serial stage design, less at the inner bag capacity of end one-level, when temporary needs heats use to the water in water tank, the water yield of heating reduces greatly, and the heat time accelerates, and energy consumption reduces; Owing to all designing a blast pipe on each inner bag, in inner bag, there will not be air-resistance phenomenon.For accessory pinna formula solar water heater water tank, can below each inner bag, design a blow-off pipe.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Embodiment: as shown in Figure 1, the multistage water tank of a kind of solar water heater, between the shell 2 of water tank and inner bag 3, be filled with insulation material 4, the front end of water tank is equipped with water inlet pipe 1, outlet pipe 8 is equipped with in rear end, inner bag 3 in shell 2 is composed in series by two, between two inner bags 3, be filled with insulation material, between two inner bags 3, with communicating pipe 6, be communicated with, the water inlet 5 of communicating pipe 6 is positioned at the top of previous stage inner bag, delivery port 10 is positioned at the middle and lower part of rear one-level inner bag, is separately installed with a blast pipe 7 above each inner bag 3; Assisted heating device 9 is arranged on the below of water tank rear end outlet pipe 8, and assisted heating device 9 stretches into the inside of afterbody inner bag; Below each inner bag 3 in shell 2, a blow-off pipe 11 is all installed.
