[0035] The following describes in detail a specific embodiment of the water storage device of the present invention by taking a hot tank as an example.

[0036] Specifically, see Figure 4 and Figure 5 , Figure 4 It is a structural schematic diagram of the water storage device of the utility model; Figure 5 yes Figure 4 A schematic cross-sectional view of one of the embodiments along line AA; Figure 6 yes Figure 4 A schematic cross-sectional view of another embodiment along line AA.

[0037] like Figures 4 to 6 As shown, the water storage device of the present invention includes a tank body 1 , a water outlet pipe 14 and a vent pipe 15 arranged on the top of the tank body 1 .

[0038] The tank body 1 is provided with a first recessed structure 1221 at a position corresponding to the water outlet pipe 14 , and the water outlet pipe 14 is provided on the first recessed structure 1221 , and / or the tank body 1 is provided with a protruding structure 1231 at a position corresponding to the ventilation pipe 15 , and the ventilation pipe 15 is provided on the protruding structure 1231 .

[0039] Through such an arrangement, that is, by arranging the water outlet pipe 14 on the first recessed structure 1221 or arranging the vent pipe 15 on the raised structure 1231, the projection of the water outlet pipe 14 in the vertical direction can be made lower than the projection of the vent pipe 15 in the vertical direction, thereby preventing the water in the water storage device from being mixed with the air entering the tank body 1 through the vent pipe 15 when being discharged through the water outlet pipe 14, thereby avoiding affecting the performance of the hot tank and greatly improving the user experience.

[0040] In a specific embodiment, Figure 5 As shown, the tank body 1 is provided with a first recessed structure 1221 at a position corresponding to the water outlet pipe 14 , and the water outlet pipe 14 is provided on the first recessed structure 1221 ; the tank body 1 is provided with a raised structure 1231 at a position corresponding to the vent pipe 15 , and the vent pipe 15 is provided on the raised structure 1231 .

[0041] In another specific embodiment, the tank body 1 is provided with a first recessed structure 1221 (not shown in the figure) only at a position corresponding to the water outlet pipe 14 , and the water outlet pipe 14 is provided on the first recessed structure 1221 .

[0042] In another possible embodiment, the tank body 1 is provided with a protruding structure 1231 (not shown in the figure) only at a position corresponding to the vent pipe 15 , and the vent pipe 15 is provided on the protruding structure 1231 .

[0043] It should be noted that, although the above three embodiments can make the projection of the water outlet pipe 14 in the vertical direction lower than the projection of the vent pipe 15 in the vertical direction, thereby avoiding the mixing of air when the water is discharged, compared with the form of only setting the first recessed structure 1221 at the position corresponding to the water outlet pipe 14 or only setting the raised structure 1231 at the position corresponding to the vent pipe 15, by simultaneously setting the first recessed structure 1221 at the position corresponding to the water outlet pipe 14 and the raised structure 1231 at the position corresponding to the vent pipe 15, a better height difference can be formed between the water outlet pipe 14 and the vent pipe 15, thereby more effectively avoiding the mixing of air when the water is discharged.
