Description
Technical Field
The utility model relates to a heat storage water tank, especially an outdoor horizontal heat storage water tank belong to water heater technical field.
Background
According to the applicant, the basic structure of the existing outdoor horizontal water heater is that a closed end cover and a capped end cover are respectively fixed at two ends of a cylindrical shell for accommodating a water storage inner container, wherein the capped end cover is provided with a detachable electrical maintenance cover, and only a rubber sealing ring is used between the closed end cover and the capped end cover to prevent water leakage, so that more screws are required to be used for fixing to ensure the sealing effect, the disassembly and the assembly are inconvenient, and after the outdoor horizontal water heater is used for a long time, the sealing performance of the sealing ring is easily reduced due to aging, the insulating performance of an internal electronic element is influenced.
Disclosure of Invention
The utility model aims to provide a: the outdoor horizontal heat storage water tank has the advantages that the electrical maintenance cover is convenient to disassemble and assemble, and the sealing can be kept for a long time, so that the insulating property and the safe use of the water heater are ensured for a long time.
In order to achieve the above purpose, the utility model discloses outdoor horizontal heat storage water tank basic technical scheme does: the cylinder-shaped casing both ends of arranging the water storage inner bag are fixed end cover respectively and are covered the end cover, and wherein the middle part opening that covers the end cover is equipped with detachable electric maintenance lid, the opening has that the week is sunken, the sunken inner edge of week has the perk turn-ups of outwards expanding, electric maintenance lid's periphery has the limit of holding with the sunken match of pressing of week, it is fixed on the gasket of embedding week recess to press the limit to press.
Because the utility model discloses the opening border recess that adds the cover end cover has constituted circuitous labyrinth seal structure with the sealing washer, consequently only needs a small amount of fasteners can hold through the pressure that presses the limit and guarantee reliably sealed for a long time to the perk turn-ups of the sunken inner edge of border has still been showing the rigidity that has strengthened the opening part, has further guaranteed sealedly.
The utility model discloses further perfect is: the middle part of the capped end cover bulges outwards, and the opening on the bulge is provided with a circumferential recess.
The utility model discloses further perfect is: the height of the tilting flanging is greater than the depth of the circumference recess.
The utility model discloses further perfection is again: the outer edge of the tilting flanging outwards exceeds the inner edge of the peripheral ring depression.
The utility model discloses still further perfect is: the depth of the circumferential depression is equal to the height of the protuberance.

Detailed Description
Example one
As shown in figures 1, 2 and 3, the outdoor horizontal heat storage water tank of the embodiment is characterized in that a water storage inner container 2 is arranged in a cylindrical shell 1, two ends of the water storage inner container are respectively fixed with a closed end cover 3 and a capped end cover 101, and a detachable electrical maintenance cover 102 is arranged at an approximately elliptical opening in the middle of the capped end cover 101.
As shown in fig. 3 and 4, the middle of the capped end cap 4 bulges outwards, the opening on the bulge is provided with a peripheral recess 107, the inner edge of the peripheral recess 107 is provided with a raised flange 106 which extends outwards at an angle of 60 ± 6 °, the height of the raised flange 106 is greater than the depth of the peripheral recess 107, the outer edge of the raised flange 106 extends outwards beyond the inner edge of the peripheral recess 107 (i.e. the axial projection area of the outer edge of the raised flange 106 is greater than the axial projection area of the inner edge of the peripheral recess 107), and the depth of the peripheral recess 107 is equal to the height of the bulge.
The electric service cover 102 has a pressing edge 108 on its periphery which fits into the peripheral recess 107, and the pressing edge 108 is pressed against the seal ring 103 fitted into the peripheral recess 107 and fixed by a tapping screw 104 with a seal gasket 105.
Compared with the prior art, the hot water tank of this embodiment has following apparent advantage:
1) the opening peripheral groove of the capped end cover and the sealing ring form a circuitous labyrinth seal structure, and the labyrinth seal structure can be pressed, fastened and kept sealed for a long time only by 2 to 4 screws;
2) the raised flanging of the middle part of the capped end cover which is raised outwards and the inner edge of the peripheral depression obviously enhances the rigidity of the opening, and further ensures the sealing;
3) except the primary waterproof structure formed by the sealing ring and the peripheral groove, even if water seeps out, the water is blocked by the raised flanging and is discharged from the gap between the electric maintenance cover and the bottom of the capped end cover along the periphery of the electric maintenance cover, so that a secondary waterproof hydrophobic structure is realized, and the insulating property of the installation area of the electric appliance element is ensured.
In addition to the embodiments described above, other variations of the present invention are possible. All technical schemes formed by adopting equivalent replacement or equivalent transformation fall within the protection scope of the utility model.
