As shown in fig. 1-3, the water heater shell comprises a shell body 1 and a decorative strip 2, wherein a through stepped groove 11 is arranged on the shell body 1, and a large opening end of the stepped groove 11 is positioned on the inner side of the shell body 1; the decoration strip 2 comprises a decoration body 21 and an insertion piece 22, the decoration body 21 is arranged on the outer side of the shell body 1, the insertion piece 22 is arranged on the decoration body 21, the insertion piece 22 can be inserted from a small opening end of the stepped groove 11, and the end portion of the insertion piece 22 can be hot-melted to form a sealing portion to be sealed at a large opening end of the stepped groove 11.

According to the water heater shell provided by the embodiment, the decorative strip 2 is arranged on the shell body 1, so that the effect of improving the attractiveness of the whole appearance surface of the water heater is achieved; through set up the ladder groove 11 and the plug connector 22 of mutually supporting respectively on housing body 1 and ornamental strip 2, and the tip of plug connector 22 can form the sealing and seal in the big mouth end in ladder groove 11 by the hot melt, when having realized housing body 1 and ornamental strip 2 firm connection, can also play good waterproof performance, guarantee that the water heater can be long-time normal use.

Specifically, as shown in fig. 3, the stepped groove 11 includes a plug groove 111 and a welding groove 112 which are vertically arranged and communicate with each other, and an outer wall of the sealing portion can be attached to an inner wall of the welding groove 112. When the plug 22 is heat-fused, the end of the plug 22 is softened until it is fused, and then the fused end is pressed into the welding groove 112 so as to be laid flat in the welding groove 112, thereby achieving the sealed connection between the housing body 1 and the molding 2. In this embodiment, the insertion groove 111 and the welding groove 112 are rectangular grooves, which is convenient for processing.

In this embodiment, the upper and lower directions refer to specific directions relative to the fixing surface after the water heater is installed.

Preferably, as shown in fig. 1 and 4, the housing body 1 is of a substantially cylindrical configuration, and the trim strip 2 is of an arcuate configuration. In order to further realize stable connection between the two, the number of the plug connectors 22 is multiple, the plug connectors 22 are arranged along the circumferential direction of the decoration strip 2 at intervals, and each plug connector 22 corresponds to one stepped groove 11. Through the mutual cooperation between a plurality of plug connectors 22 and a plurality of ladder grooves 11, can increase the area of contact between shell body 1 and ornamental strip 2, improve the stability of connecting between the two. Optionally, the plurality of plug connectors 22 are uniformly arranged along the circumferential direction of the decoration body 21 at intervals, so that the uniformity of stress on the decoration body 21 can be ensured on the premise of ensuring stable connection between the housing body 1 and the decoration strip 2.

In the present embodiment, the stepped groove 11 penetrates the case body 1 from the groove bottom 121 of the first receiving groove 12.

Further, as shown in fig. 5, a water guide platform 13 is further disposed on the bottom 121 of the first accommodating groove 12, the water guide platform 13 is disposed around the periphery of the stepped groove 11, and an upper surface of the water guide platform 13 is gradually inclined downward toward the outer side of the housing body 1. Through setting up water guide table 13, even in the gap of outside steam from shell body 1 and ornamental strip 2 top entered into first storage tank 12, water guide table 13 also can carry out the drainage to this steam to make it flow from the gap of shell body 1 with ornamental strip 2 below, thereby prevent that steam from getting into shell body 1's inside, influence water tank control circuit's normal use.

In the present embodiment, as shown in fig. 5, the cross-sectional shape of the water guide platform 13 is a U-shaped structure, two free ends of the U-shaped structure are connected to the groove wall of the first accommodating groove 12, and the water guide platform 13 of the U-shaped structure is enclosed around the notch of the insertion groove 111. In order to prevent external moisture from entering the inside of the housing body 1 from the gap between the plug 22 and the water guide table 13, the thickness of the plug 22 is reduced from top to bottom, and when the lower surface of the decoration body 21 is attached to the groove bottom 121, the outer wall of the plug 22 can be attached to the inner wall of the water guide table 13. With the arrangement, on one hand, the guide can be provided for the process of inserting the plug-in connector 22 into the stepped groove 11, and the installation is convenient; on the other hand, after the plug-in components 22 and the stepped grooves 11 are plugged in place, the outer walls of the plug-in components 22 can be attached to the inner walls of the water guide platforms 13, sealing matching between the plug-in components 22 and the water guide platforms 13 can be achieved, and water vapor is prevented from entering the shell body 1 from gaps between the plug-in components 22 and the water guide platforms 13 and affecting normal use of the water tank control circuit.

In this embodiment, the height of the water guide table 13 is 1mm to 3mm, and the wall thickness is 0.6mm to 1 mm.

Optionally, a sealing element may be further disposed inside the water guiding platform 13 to further improve the sealing effect between the plug 22 and the water guiding platform 13. Wherein, the sealing member can adopt the rubber material to make, and convenient for obtaining materials, manufacturing cost is lower.

Further, as shown in fig. 5 to 8, a second receiving groove 15 is disposed at a position corresponding to the first receiving groove 12 on the top of the housing body 1, and the second receiving groove 15 is communicated with the first receiving groove 12; the decoration body 21 includes a first body 211 and a second body 212 disposed at an included angle and connected to each other, an inner side surface of the first body 211 is attached to a groove wall of the first accommodating groove 12, an inner side surface of the second body 212 is attached to a groove wall of the second accommodating groove 15, and an upper surface of the second body 212 is flush with an upper surface of the housing body 1. By adopting the arrangement, the decorative body 21 can completely shield the appearance gap on the front surface of the top of the shell body 1, and the appearance of the whole appearance surface of the water heater shell is further ensured. Wherein, the width of the second accommodating groove 15 is 1 mm-2 mm, and the depth of the second accommodating groove is 0.5 mm-1 mm.

In order to facilitate the installation between the housing body 1 and the trim strip 2, as shown in fig. 6, first guide surfaces 2111 are disposed on both sides of the trim body 21, a second guide surface 122 is disposed on a groove wall of the first accommodating groove 12 corresponding to the first guide surface 2111, and the first guide surface 2111 can be attached to the second guide surface 122. Specifically, when the trim 2 is attached to the housing body 1, the trim 2 may be attached from above the housing body 1, the first guide surface 2111 may be slid downward along the second guide surface 122, and the plug 22 may be inserted into the stepped groove 11. By providing the first guide surface 2111 and the second guide surface 122 which are fitted to each other, a guiding function of the trim strip 2 at the time of mounting with the housing body 1 can be performed to simplify the mounting process.

Further, as shown in fig. 5, 7 and 8, the trim strip 2 further includes a positioning column 23, the positioning column 23 is disposed on the trim body 21, the housing body 1 is provided with a positioning hole 14, and the positioning column 23 can be inserted into the positioning hole 14.
