Abstract
Electric heater twin-tub plastic inner container described in the utility model, is made up of two interconnective inner bags, has the water channel be interconnected between two inner bags, and local matrix material is interconnected, and two inner bags are disposable blow molding; The cross section of two inner bags can be non-circular or circular; Meanwhile, at plastic inner container appearance local or whole parcel layer of metal thin plates, it is shaped with the hard point being connected with shell and hanging.
Description
Technical field
The present invention relates to electric heater twin-tub plastic inner container, relate generally to inner bag that the is closed or manufacture of outlet open-type twin-tub plastic material, and outside at it, the structure of local or all parcel layer of metal thin plate.
Background technology
China Patent Publication No. CN101968263A discloses " water heater liner of hollow blow molding ", and this patent application exists following defect:
1, this patent application claims 1 " overall shape of water heater liner is a cylinder body ", is defined as cylinder body.
2, this patent application claims 1 " upper design more than three chimbs (2) of sidewall (1) of cylinder body ", this kind of inside configuration is completely hollow cylinder body, and after in-built hot water, water tank can expand and extend, and can not use.
3, this patent application claims 4 " vertical (axis is at vertical direction) opens a hole (6) in the center of its lower surface (5) "; Claim 5 " (axis in the horizontal direction) of horizontal type opens a hole (6) in the center of its side (1) "; Finding out from accompanying drawing 1 and accompanying drawing 2, is all flat mouth inside and outside hole (6), this opening mode, and current any unit or individual cannot make the close packaged water of the water heater liner of this patent application, more can not pressure-bearing.
4, according to GB4706.12-200622,101 " closed water heaters be directly connected with water source, its rated pressure at least should be 0.6Mpa, and test pressure is 2 times, i.e. 1.2Mpa "; The inner bag of this patent application can not bear this pressure, can not make closed water heater.
5, the water heater liner of the hollow blow molding of this patent application, must bear the suspended weights (standard gauge is decided to be two times of water weight) of 50-100kg, and must be connected with shell, this patent application no this item functional description after dress water.
In sum, this patent application does not obviously possess three property principles of patent, and do not have practicality, described practicality refers to that this invention can manufacture or use, and can produce good effect, but this patent application can not create practical product at all.
Summary of the invention
The present invention improves " water heater liner of hollow blow molding ", after improvement, is not the inner bag of " cylinder body " but twin-tub form.
Described twin-tub plastic material inner bag, is be made up of two interconnective inner bags, has the water channel 12 be interconnected between two inner bags, and local matrix material is interconnected, two disposable blow moldings of inner bag, and the cross sectional shape of two inner bags is non-circular or circular; Twin-tub plastic inner container, also can be single shaping, is then mechanically connected to become twin-tub plastic inner container.Meanwhile, at twin-tub plastic inner container appearance local or whole parcel layer of metal thin plates 2, it is shaped with the hard point 10 being connected with shell and hanging.
Need in plastic inner container to install various parts, therefore inner bag one end should have hole, hole 3 has flange to the horn-type structure extended out; With lid 5 and two semicircle clamp clips 6 splitting to the encapsulating method at aperture 3 place of trumpet type, by multiple screw 8 by having flange and clamping to the tubaeform mouth 3 extended out and blind flange 4 on seal 7 and plastic inner container, ensure that bearing setting pressure does not leak.
Advantage of the present invention substitutes steel with plastics, can reduce manufacturing cost; Do not need the workman be skilled in technique, and intensity is high simultaneously, bears pressure large, can not leak, improve product quality.
Accompanying drawing explanation
Fig. 1 is the twin-tub plastic inner container schematic diagram of flange to the tubaeform mouth extended out;
Fig. 2 is Figure 1A-A sectional view, and Fig. 3 is Figure 1B-B sectional view;
Fig. 4 is that Fig. 1 with Fig. 3 local parcel is with the schematic diagram of sheet metal being connected and hanging hard point;
Fig. 5 is plastic inner container sealed structural representation;
Detailed description of the invention
Be described below in conjunction with accompanying drawing, electric heater twin-tub plastic inner container 1 in accompanying drawing, with connect and hang hard point sheet metal 2, have flange to the horn mouth 3 (or claiming hole 3) extended out, flange part 4, lid 5, two semicircle clamping elements 6, seal 7, screw 8, wall of inner container 9, hang hard point 10, electrothermal tube 11, aquaporin 12, base material connecting portion 13.
Fig. 1 is electric heater twin-tub plastic inner container, and at plastic inner container 1 appearance local or whole sheet metal 2 wrapped up with connecting and hang hard point 10.
Flange is shaped with to the tubaeform mouth 3 (or claiming hole 3) extended out in Fig. 1, on the right side of twin-tub plastic inner container, Fig. 5 is the structural representation that flange carries out to the tubaeform mouth extended out sealing, at flange to mounting flange part on the tubaeform mouth 3 extended out 4 (flange part 4 can fill electrothermal tube, temperature tube or limit warm temperature controller), with lid 5 and two semicircle clamp clips 6 splitting, with multiple screw 8 by having flange and clamping to the tubaeform mouth 3 extended out and flange part 4 on seal 7 and plastic inner container, form closed container.
The present invention is applicable to vertical and horizontal various electric heater.
