By groove is arranged on end cap, can avoid producing hole former due to mould thereby that form on end cap, therefore needn't increase the operation that the special messenger pastes foam-rubber cushion in order to prevent the foamed material flash, thereby reduce operation, and reduce cost.
The utility model is preferred, and described groove is draw-in groove, and described end cap coordinates by the card column clamping of corresponding setting on described draw-in groove and described service cover.
By draw-in groove is set on end cap, card column is set on service cover, and with the mode of card column clamping, end cap is engaged by draw-in groove with service cover, make simple in structure, convenient disassembly.
The utility model is preferred, and described end cap has cannelure, and described cannelure comprises interior gear, outer gear and bottom land, and described draw-in groove is a plurality of, and is arranged on and blocks in described.
The utility model is preferred, and described draw-in groove is by described interior gear end face opening and circumferentially form the groove shape along it.
The utility model is preferred, and described bottom land and described draw-in groove are spaced apart.
Described bottom land and described draw-in groove are spaced apart, namely, when card column coordinates with the clamping of draw-in groove, this cooperation place and bottom land maintain a certain distance, and the water that the junction by the outside by end cap and service cover enters first arrives trench bottom, owing to leaving certain distance between trench bottom and this clamping cooperation place, therefore, water can not enter this clamping cooperation place, is arranged in the overflow launder of downside but flow into along trench bottom, and has reached the effect of waterproof.
The utility model is preferred, the ellipticity cylindricality that described card column circumferentially arranges for long edge.
The utility model is preferred, and described groove is spiral groove, and described end cap coordinates by rotation by the spiral groove of corresponding setting on described spiral groove and described service cover.
End cap and service cover are fastening by the rotation fit system, make structure simpler, convenient disassembly.
The utility model is preferred, and described end cap and described service cover are also fastening by being threaded of screw.
Employing connects and fixes or rotates the fixing fixed form of using with the screw secure fit of fit system, makes structure more firm.
The utility model is preferred, is provided with electric apparatus room between described end cap and described service cover, and described service cover is fixed on described electric apparatus room by being threaded of screw.
Water heater end cover structure of the present utility model, by groove is arranged on end cap, can avoid producing hole former due to mould thereby that form on end cap, therefore needn't increase the operation that the special messenger pastes foam-rubber cushion in order to prevent the foamed material flash, thereby reduced operation, and reduced cost.

[description of symbols in figure]
1 water heater; 2 end caps; 21 through holes; 22 bottom surface openings; 23 cannelures; 231 interior gears; 232 outer gears; 233 bottom lands; 24 draw-in grooves; 25 column mount pads; 3 service cover; 31 flanges; 32 card columns; 33 screw mounting grooves.
The specific embodiment
The below is take the right end cap of water heater as example, and the water heater end cover structure that by reference to the accompanying drawings specific embodiment of the present utility model is provided describes.
The right end cap of this water heater 1 comprises the annular end cap 2 that is contained on the water heater fuselage and is used for the service cover 3 of the opening of closed end cap 2, at the internal main of right end cap, the electric components such as computer board, temperature controller will be installed.Service cover 3 is arranged on end cap 2 removably, in order to water heater is maintained.In following description, described inner edge all refers to a radially side in the centre of close end cap 2 (or service cover 3); Described inboard (inner surface) all refers to vertically the side towards water heater master cylinder inside; The described outside (outer surface) all refers to vertically the side away from water heater master cylinder inside.
When mounted, with the bottom surface opening 22 on service cover 3 covering end caps 2, rotation service cover 3 is fastened in the draw-in groove 24 of end cap 2 card column 32 on service cover 3, screw is passed in the screwed hole of column mount pad 25 that through hole whorls in circular screw mounting groove 33 on service cover 3 are connected to end cap 2, thereby retrained the rotation of service cover 3 with respect to end cap 2.In when dismounting, first back out screw, then with the rightabout rotation service cover 3 when installing, the draw-in groove 24 that the card column 32 on service cover 3 is broken away from end caps 2, thus pull down service cover 3.
In the installment state of service cover 3 and end cap 2, due to the clamping cooperation place of service cover 3 with end cap 2, it is the outside of the bottom land 233 of the clamped position of card column 32 and draw-in groove 24 cannelure 23 that is positioned at end cap 2, therefore when the joint that has water from service cover 3 and end cap 2 enters, can flow to the overflow launder that is arranged in water heater end downside along the bottom land 233 of this cannelure 23, and can not invade the electric component that is arranged in this water heater right end cap 2 inside by draw-in groove 24.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
For example, in the present embodiment, adopt the interface arrangment of end cap 2 and service cover 3, but be not limited to this, also corresponding spiral groove can be set on end cap 2 and service cover 3, and the mode that adopts rotation to coordinate realizes fixing.
