Warm nature energy.It addition, compared to existing technologies, also reduce the packing volume of foam element 331, by increasing foaming sky
Between in 5 the packing volume of foam material to improve the heat-insulating property of water heater 100.
With reference to Fig. 5, it is that H, H can be 0 along the distance between the radial direction of shell 1 between foam element 331 and dividing plate 32
In the range of 2 millimeters.Foam element 331 has certain elasticity, may be used for sealing between foam element 331 and dividing plate 32
Gap, it is also possible to meet the requirement expanded with heat and contract with cold.
Wherein, H can be 0,0.5 millimeter, 0.8 millimeter, 1.0 millimeters, 1.4 millimeters, 1.8 millimeters, 2.0 millimeters etc..
According to embodiments more of the present utility model, dividing plate 32 and body 31 can be integrated the working of plastics of injection mo(u)lding.
Thus, it is possible to simplified processing process, reduction cost, thus it is easily achieved the batch production of cover plate 3, it is also possible to simplify hot water
The assembling process of device 100, improves efficiency.
It addition, according to product structure demand, cover plate 3 such as working of plastics detachable with foam element 331 become several parts, with fall
The assembly technology difficulty of low water heater 100.
In specific embodiments more of the present utility model, with reference to Fig. 1, shell 1 includes fore shell 11 and back cover 12, fore shell 11
Can be connected in the way of being connected by screw with back cover 12.Thus so that the installation and removal of fore shell 11 and back cover 12 are more
Convenient, thus it is prone to the maintenance of water heater 100.
Certainly, in other embodiments of the present utility model, fore shell 11 and back cover 12 can also the most such as by
The mode of foaming mould extruding is connected.The concrete connected mode of fore shell 11 and back cover 12 can adaptability according to actual needs
Adjust.
Below in conjunction with Fig. 1 to Fig. 5, a specific embodiment according to this utility model water heater 100 is described.
The water heater 100 blocking up bubble structure with gallbladder mouth that this utility model provides, can reduce water heater 100 internal insulation foam element
The volume of 331, in increase foaming space 5, the packing volume of foam material, improves the heat-insulating property of product, reduces product foaming change
Shape probability, reduces product design volume.
Specifically, cover plate 3 such as working of plastics coordinates with inner bag 2 and shell 1, pastes a circle sponge in gallbladder mouth 21 local and uses
Gap between seal cover board 3 such as working of plastics and the gallbladder mouth 21 of inner bag 2.Foam element 331 is placed on cover plate 3 and such as moulds
Between materials and parts and shell 1, foam element 331 is for the gap between sealed plastic part and shell 1, simultaneously, it is possible to use bubble
Foam member 331 buffer product foaming and intumescing power, reduces product design foaming deformation probability, and during foaming, foam material encases whole the most completely
Individual inner bag 2, because the heat-insulating property of foam material is far above insulating foam part 331, to this end, this utility model is by by gallbladder mouth 21
The thickness of the insulating foam part 331 at place reduces more than 10mm (such as 12 millimeters or 15 millimeters), increases in foaming space 5
The packing volume of foam material, the material thickness of cover plate 3 such as working of plastics is relatively thin simultaneously so that electrical part can be directly installed on working of plastics
On, be so equivalent to decrease electrical part installation footprint, shorten gallbladder mouth 21 and arrive the distance between shell 1, reduce and produce
Product contour length.
Protection point of the present utility model is that cover plate 3 such as working of plastics coordinates with inner bag 2 and shell 1, and foam element 331 is placed on
Between cover plate 3 such as working of plastics and shell 1, utilize the process structure feature of cover plate 3 such as working of plastics, maximum likelihood
With the stifled bubble of cover plate 3 such as working of plastics, then it is being locally filled with foam element 331 and sealing member 4 such as sponge seals, significantly
Simplify the processability of product structure of water heater 100, add the packing volume of foam material in foaming space 5, improve water heater 100
Heat-insulating property, then utilize foam element 331 to buffer foaming and intumescing power, reduce the foaming deformation probability of water heater 100, with
Time electrical control member etc. can be installed on cover plate 3 such as working of plastics, reduce water heater 100 overall dimensions.
Water heater 100 according to this utility model embodiment, it is possible to reduce the packing volume of foam element 331, increases foaming space
The packing volume of foam material in 5 such that it is able to improve the heat-insulating property of water heater 100.It addition, utilize the slow of foam element 331
Rush foaming and intumescing power, reduce the foaming deformation probability of water heater 100, electrical control member etc. can be installed to cover plate 3 simultaneously and such as mould
