Description
Technical field
The utility model relates to electric heater device field more particularly to instant electric water heaters.
Background technique
Instant electric water heater is that one kind can heat component by electronics quickly to heat flowing water, and can pass through electricity
Road controls water temperature, flow velocity, power etc., and water temperature is made to reach the water heater of the temperature of suitable human body bathing；Current electric heater one
As be water and heating element heat exchange by way of so that water temperature increase；But current heat exchange mode heat loss is serious, heating
It is at high cost, and water temperature is not high.
Utility model content
The purpose of the utility model is to provide heat loss is reduced, the instant electric water heater of heating cost is reduced.
The technical solution of the utility model is as follows：
The shell installed outside instant electric water heater, including electric heating gallbladder and electric heating gallbladder；The electric heating gallbladder includes rectangle
Heating element, heating element successively include the first metal tube layer and the second metal tube layer from inside to outside；First, second metal
Tube layer encompasses rectangle by metal tube parallel connection；The first metal tube layer is equipped with the first water inlet pipe and the first outlet pipe, the
Two metal tube layer are equipped with the second water inlet pipe and the second outlet pipe, and second outlet pipe and the first water inlet pipe are continuous.
The metal tube of the first, second metal tube layer can use aluminum pipe, stainless steel tube or copper pipe.Using aluminum pipe,
Stainless steel tube and copper pipe good heat conductivity.
Fire-retardant sound absorbing layer is folded in the shell.Due to being additionally provided with fire-retardant sound absorbing layer in shell, reduce when exchanging heat
Noise.
The fire-retardant sound absorbing layer can use fire-retardant acoustical cotton, fire-retardant abatvoix or fire-retardant deadener felt.Using fire-retardant suction
Sound cotton, fire-retardant abatvoix or fire-retardant deadener felt, sound-absorbing and flame-retardant effect are good.
The metal tube rectangular in cross-section of the first, second metal tube layer.Due to metal tube rectangular in cross-section, on the one hand increase
On the other hand mass-flow speed becomes larger with heating element contact area, improve heat exchange efficiency.
The utility model has the beneficial effects that：The shape of double layer of metal tube layer is adapted with heating element, convenient for electric heating member
The installation of part；Due to having double layer of metal photosphere outside heating element, on the one hand increases heat exchange area and extend heat-exchange time, energy is big
It is big to improve heat exchange efficiency, the second metal tube layer that another aspect water flow can first pass through outer layer preheated after again by the second metal
Second outlet pipe of tube layer enters the first metal tube layer and is further exchanged heat, and improves heat exchange efficiency.
Detailed description of the invention
Through the following detailed description taken in conjunction with the accompanying drawings, the utility model objects, features and advantages above-mentioned and other will
It becomes apparent.
Wherein：FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model electric heating bladder structure schematic diagram；
In attached drawing, 1 is electric heating gallbladder, and 2 be shell, and 3 be heating element, and 4 be the first metal tube layer, and 5 be the second metal tube layer,
6 be the first water inlet pipe, and 7 be the first outlet pipe, and 8 be the second water inlet pipe, and 9 be the second outlet pipe, and 10 be fire-retardant sound absorbing layer.
Specific embodiment
Shell 2 shown in Figure 1, being installed outside instant electric water heater, including electric heating gallbladder 1 and electric heating gallbladder；The electricity
Hot gallbladder includes the heating element 3 of rectangle, and heating element successively includes the first metal tube layer 4 and the second metal tube layer 5 from inside to outside；
The first, second metal tube layer encompasses rectangle by metal tube parallel connection；The first metal tube layer is equipped with the first water inlet
Pipe 6 and the first outlet pipe 7, the second metal tube layer are equipped with the second water inlet pipe 8 and the second outlet pipe 9, second outlet pipe and the
One water inlet pipe is continuous.The shape of double layer of metal tube layer is adapted with heating element, convenient for the installation of heating element；Due to electric heating member
There is double layer of metal photosphere outside part, on the one hand increases heat exchange area and extend heat-exchange time, heat exchange efficiency can be greatly improved, it is another
The second metal tube layer that aspect water flow can first pass through outer layer preheated after again by the second outlet pipe of the second metal tube layer into
Enter the first metal tube layer further to be exchanged heat, improves heat exchange efficiency.
The metal tube of the first, second metal tube layer can use aluminum pipe, stainless steel tube or copper pipe.Using aluminum pipe,
Stainless steel tube and copper pipe good heat conductivity.
Fire-retardant sound absorbing layer 10 is folded in the shell.Due to being additionally provided with fire-retardant sound absorbing layer in shell, when reducing heat exchange
Noise.
The fire-retardant sound absorbing layer can use fire-retardant acoustical cotton, fire-retardant abatvoix or fire-retardant deadener felt.Using fire-retardant suction
Sound cotton, fire-retardant abatvoix or fire-retardant deadener felt, sound-absorbing and flame-retardant effect are good.
The metal tube rectangular in cross-section of the first, second metal tube layer.Due to metal tube rectangular in cross-section, on the one hand increase
On the other hand mass-flow speed becomes larger with heating element contact area, improve heat exchange efficiency.
The above is only the preferred embodiment of the utility model, not does limit in any form to the utility model
System, it is all according to any simple modification to the above embodiments in the technical essence of the utility model, equivalent variations, fall
Enter within the protection scope of the utility model.
