Abstract
The utility model relates to a water storage type electric water heater, which comprises a casing and a water storage inner liner. The inner liner is formed by the coiling of pipelines to form into a multi-pipeline combined inner liner; a water inlet pipe of cold water enters from a pipeline on the extreme lower position of the multi-pipeline combined inner liner near the position of an electric heating pipe; a pipeline on the extreme higher position is connected with a water outlet pipe of hot water. Because the inner liner is formed by the connection of a plurality of small cross-section pipelines in sequence, cold water which enters from the water inlet pipe can reach a water outlet position only after most of heated hot water in each of the pipelines is exhausted. The utility model can weaken the mixing of hot water and cold water furthest to make the hot water form directional flow; the water output of the hot water is improved and energy consumption is reduced.
Description
The utility model relates to a kind of water-storage electric heater.
Existing water-storage electric heater kind is more, and structure is different.Its inner bag generally is to be made by the bigger cavity of volume, the ratio great disparity in internal bladder cavity body section and water inlet pipe and water outlet pipe cross section, can not control the flow direction of the cold water that newly enters during use, the hot water at some position fails in time to discharge from the hot water outlet pipe, can not form the hot and cold water directed flow, influence the hot water amount that of water heater, make its energy consumption bigger.In addition, the inner bag of traditional water-storage electric heater generally all adopts metal material to form through welding processing, is subjected to effects limit such as technology, very easily produces seepage in the use.
The purpose of this utility model aims to provide a kind of water-storage electric heater that makes the hot and cold water directed flow, improves the thermal efficiency, cuts down the consumption of energy, to overcome the deficiencies in the prior art part.
A kind of water-storage electric heater by this purpose design comprises shell and water storage inner bag, and its architectural feature is that described water storage inner bag is coiled to form multitube road combination inner bag by pipeline; This inner bag one end is provided with cold water inlet and electric heater, and the other end is connected with the hot water outlet pipe.
Described cold water inlet enters from the position of the close electrothermal tube of pipeline of the extreme lower position of multitube road combination inner bag; The pipeline of extreme higher position is connected with the hot water outlet pipe.For strengthening fuel factor, cold water inlet can be made into helical coil, and around being close to electrothermal tube.
The pipeline of described multitube road combination inner bag can be individual layer, bilayer or multilayer.Its mouth of pipe combined cross section can be the combination of in-line, isosceles triangle, groined type, quincunx or these shapes.The mouth of pipe combined cross section of multitube road combination inner bag also can be two or more quincunx linking to each other.The single mouth of pipe cross section of multitube road combination inner bag is generally circle, also can be non-circular or other geometry.Connect successively by elbow between each root pipeline of described multitube road combination inner bag, adopt mechanical type to clamp sealing, seal with screwed joint or welding.
Because this water storage inner bag is multitube road combination inner bag, electrothermal tube is arranged on the top of the pipeline of inner bag extreme lower position, water inlet pipe is again near electrothermal tube, and according to the flowing law that hot water rises, cold water descends, electrothermal tube must be heated to setting value with the water of whole inner bag when energising was used.Because inner bag is that small bore multitube road connects to form successively,, after discharging, the hot water overwhelming majority that the cold water that enters from water inlet pipe can only heat just can reach the delivery port position in each pipeline according to the flowing law of aforementioned water.Like this, just can weaken the mixing of hot and cold water to greatest extent, make hot water form directed flow.It is compared with the inner bag of the same capability of existing form, has improved the water yield of hot water greatly, and energy consumption is reduced.Add that this inner-tube structure can adopt mechanical type to connect but not welding, and can adopt engineering plastics to make, can greatly reduce hidden leakage defect.
Adopt multitube road combination inner bag, also broken the idea that traditional water-storage electric heater is divided into vertical and pressure-bearing type, can design the profile of electric heater arbitrarily.
The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 is the right TV structure schematic diagram of Fig. 1;
Fig. 3 is the backsight structural representation of Fig. 1;
Fig. 4 is the D-D cross-sectional view among Fig. 3;
Fig. 5 is the C-C cross-sectional view among Fig. 2;
Fig. 6 is the another kind of fastening structure schematic diagram of the C-C section among Fig. 2.
Referring to Fig. 1-Fig. 3, this inner container of electric water heater is coiled to form by pipeline 9, and its mouth of pipe compound section is arranged in two plum blossom shapes, and as shown in Figure 4, it is connected in sequence by the elbow 5 of pipeline 9-1 to 9-12 between two pipes.Electrothermal tube 3 is arranged on the end of the pipeline 9-1 of extreme lower position, cold water inlet 1 in the shape of a spiral shape pipe 4 around being close to electrothermal tube 3.Hot water outlet pipe 2 draws from the end of the pipeline 9-12 of extreme higher position.Be provided with between each pipeline locating clamp plate 10 is installed, to guarantee the location of each pipeline.Both sides also are provided with mounting support hanger 8.
The fastening means of pipeline and elbow is provided with sealing ring 7 between elbow 5 and pipeline 9-10 and the 9-11 as shown in Figure 5, through spiral cover 6 screwing hermetics.Another kind of fastening means is provided with sealing ring 7 between elbow 5 and pipeline 9-10 and the 9-11 as shown in Figure 6, adopts ring flange 11 and bolt 12 fit sealings.
The pipeline of described multitube road combination inner bag and connecting bend are made with metal material or nonmetallic materials such as engineering plastics.
