Referring to fig. 1, an embodiment of the present application provides a water heater 1, and fig. 2 is a top view of the water heater 1, where the water heater 1 includes a housing 10, and a first mounting hole 11 is provided on the housing 10.

Referring to fig. 3 and 4, the water heater includes a liner 20, the liner 20 being installed inside the housing 10, the liner 20 being formed with a water storage chamber 21, the water storage chamber 21 being for storing water for a user. A second mounting hole 22 is provided on a side of the inner container 20 near the first mounting hole 11, and the second mounting hole 22 communicates with the water storage chamber 21 such that water in the water storage chamber 21 can be discharged to the outside of the water storage chamber 21 through the second mounting hole 22.

The first mounting hole 11 and the second mounting hole 22 are correspondingly arranged, the water heater 1 further comprises a water outlet electricity preventing wall 30, and the water outlet electricity preventing wall 30 is arranged at the positions of the first mounting hole 11 and the second mounting hole 22. The water-out electricity-proof wall 30 comprises a first wall body 31 and a water outlet pipe 32, wherein the first wall body 31 is installed in the first installation hole 11 and is arranged along the axial direction of the first installation hole 11, one end of the first wall body 31 extends out of the first installation hole 11 to the outside, and the first wall body 31 is connected with the shell 10.

Illustratively, the first wall 31 may be coupled to the housing 10 by a threaded connection, a snap fit, or the like.

The first wall 31 has a through hole (not shown in the drawings) corresponding to the first mounting hole 11 and the second mounting hole 22, and the through hole penetrates the first wall 31. The water outlet pipe 32 can penetrate through the second mounting hole 22 and the first mounting hole 11 to extend into the through hole, namely, one end of the water outlet pipe 32 is positioned in the water storage cavity 21, and the other end of the water outlet pipe 32 extends to one end, close to the outside, of the through hole, so that water in the water storage cavity 21 is discharged to the outside along the water outlet pipe 32.

The water outlet pipe 32 is in sealing connection with the inner container 20, so that water in the water storage cavity 21 cannot flow out along a gap between the water outlet pipe 32 and the second mounting hole 22 on the inner container 20, and the working reliability of the water heater 1 is ensured.

The outlet pipe 32 is also connected to the first wall 31 to fix the outlet pipe 32 in the first wall 31.

Illustratively, an internal thread is provided on the inner wall of the through hole, and an external thread is provided on the outer circumferential wall of the portion of the outlet pipe 32 located in the through hole, the internal thread being adapted to the external thread, so that the outlet pipe 32 can be screwed into the through hole and the outlet pipe 32 is locked to the first wall 31.

Illustratively, the material of the water outlet pipe 32 may be polyamide (Polyamide, PA for short), random copolymer polypropylene (Polypropylene Random, PPR for short), or the like. Wherein, PA and PPR have excellent electrical insulation properties, excellent heat resistance and high mechanical strength, so that the water outlet pipe 32 is insulated from other parts of the water heater 1. When the water heater 1 is electrified to work, even if electricity exists in the water storage cavity 21, the water can be attenuated by the resistance of the water when passing through the insulated water outlet pipe 32, so that the purpose of blocking the electricity is achieved, and the water flowing out of the water heater 1 has extremely weak current.

With continued reference to fig. 3, in the related art, only one water flow channel is provided in the water outlet pipe of the water outlet anti-electric wall, the water outlet anti-electric wall is installed in a region with poor water quality, the resistivity of water is low, and the resistance of water in the water outlet anti-electric wall is possibly caused to be small, so that the leakage voltage of water sharing is small, the human body sharing voltage is large, and therefore, a user has the risk of electric shock in the use process, and the safe use of the user is affected.

With continued reference to fig. 4, the water outlet pipe 32 of the water heater 1 provided by the application is provided with a plurality of water flow channels, so that the water flow path can be prolonged, and the discharging effect of the water outlet electricity-proof wall 30 can be improved.

Referring to fig. 5, the water outlet pipe 32 includes a first water inlet channel 321, a first middle channel 322 and a first water outlet channel 323 extending along an axial direction thereof, water in the water storage chamber 21 can sequentially flow through the first water inlet channel 321, the first middle channel 322 and the first water outlet channel 323 and then be discharged to the outside, and a path through which the water flows is longer than a length of the water outlet pipe 32.

Thus, the water path with the electricity-proof function is formed, the length of the water path is greater than that of the water outlet pipe 32, so that the resistance of water flow is increased, the voltage shared by the water flow is increased, the voltage of the water flow flowing to the user is reduced, and the safety of the user in the use process is further ensured.

It is to be understood that the first water inlet channel 321, the first middle channel 322 and the first water outlet channel 323 may be linear channels, or spiral channels, as long as the length of the water flowing through the channel is longer than that of the water outlet tube 32.

In some embodiments, the first water inlet channel 321 and the first middle channel 322 are spaced apart in a first direction, the first middle channel 322 and the first water outlet channel 323 are spaced apart in a second direction, and the first direction and the second direction are perpendicular to the axial direction of the water outlet pipe 32. The axial direction of the water outlet pipe 32 is the up-down direction, and then the first direction and the second direction are both horizontal directions. That is, the first water inlet channel 321 and the first middle channel 322 are disposed at intervals in the horizontal direction, and the first middle channel 322 and the first water outlet channel 323 are disposed at intervals in the horizontal direction, so that the space in the pipe of the water outlet pipe 32 can be fully utilized, the structure is compact, and the volume of the water outlet electricity preventing wall 30 is reduced.

Illustratively, the first direction and the second direction may be disposed at an included angle, for example, when the included angle between the first direction and the second direction is 60 °, the first water inlet channel 321, the first middle channel 322 and the first water outlet channel 323 may be arranged in a triangle, so that the space utilization rate in the water outlet pipe 32 can be maximized, the water outlet flow of the water outlet pipe 32 can be increased while the length of the water flowing path can be ensured to be greater than the length of the water outlet pipe 32, and the water use experience of the user is improved.

With continued reference to fig. 5, it may be understood that the first direction may also be parallel to the second direction, and in this case, the first water inlet channel 321, the first middle channel 322, and the first water outlet channel 323 are disposed at intervals along the same horizontal direction.

In some embodiments, in the first direction, the projection of at least a portion of the first intermediate channel 322 coincides with the projection of the first water inlet channel 321. I.e. in the first direction, a partial projection of the first intermediate channel 322 coincides with a projection of the first water inlet channel 321, or a complete projection of the first intermediate channel 322 coincides with a projection of the first water inlet channel 321. Thus, along the axial direction of the water outlet pipe 32, the length of the first middle channel 322 is greater than or equal to the length of the first water inlet channel 321, which is favorable for prolonging the path through which water flows, so as to increase the resistance of the water flow, increase the voltage shared by the water flow, reduce the voltage of the water flow flowing to the user, and further ensure the safety of the user in the use process.

In some other embodiments, in the second direction, the projection of at least part of the first intermediate channel 322 coincides with the projection of the first outlet channel 323. I.e. in the second direction, a partial projection of the first intermediate channel 322 coincides with a projection of the first outlet channel 323, or a complete projection of the first intermediate channel 322 coincides with a projection of the first outlet channel 323. Thus, the length of the first middle channel 322 is greater than or equal to the length of the first water outlet channel 323, which is favorable for prolonging the path through which water flows, so that the resistance of the water flow is increased, the voltage shared by the water flow is increased, the voltage of the water flow flowing to the user is reduced, and the safety of the user in the use process is further ensured.

In some other embodiments, in the first direction, the projection of at least a portion of the first intermediate channel 322 coincides with the projection of the first water inlet channel 321. In the second direction, the projection of at least part of the first intermediate channel 322 coincides with the projection of the first outlet channel 323. So, the length of the first middle channel 322 is greater than or equal to the length of the first water inlet channel 321 and the length of the first water outlet channel 323, which is favorable for prolonging the path through which water flows, thereby increasing the resistance of water flow, increasing the voltage shared by the water flow, reducing the voltage of the water flow flowing to the user, and further ensuring the safety of the user in the use process.

It will be appreciated that the length of the first water inlet channel 321 and the length of the first water outlet channel 323 may be greater than the length of the first middle channel 322 along the axial direction of the water outlet pipe 32, so long as the water flowing path is ensured to be greater than the length of the water outlet pipe 32.

With continued reference to fig. 5, in some possible embodiments, the first water inlet channel 321, the first middle channel 322, and the first water outlet channel 323 are disposed in a straight line, and the lengths of the first water inlet channel 321, the first middle channel 322, and the first water outlet channel 323 are all the same as the length of the water outlet pipe 32. Thus, the water flowing through the path is longer than the length of the water outlet pipe 32, so that the use safety of the user can be ensured.

With continued reference to fig. 4 and 5, in some embodiments, the first water inlet channel 321, the first middle channel 322 and the first water outlet channel 323 are all provided with a water inlet end and a water outlet end, so that water in the water storage cavity 21 enters from the water inlet end of the first water inlet channel 321, flows through the first water inlet channel 321, enters from the water outlet end of the first water inlet channel 321 into the water inlet end of the first middle channel 322, flows along the first middle channel 322 from the water outlet end of the first middle channel 322 to the water inlet end of the first water outlet channel 323, and finally flows through the first water outlet channel 323 to the water outlet end of the first water outlet channel 323 to be discharged. In this way, the water in the water storage chamber 21 can flow through the first water inlet channel 321, the first middle channel 322 and the first water outlet channel 323 in sequence and then be discharged to the outside, and the path of the water flowing through is greater than the length of the water outlet pipe 32.

In this way, the length of the water flowing path is greater than the length of the water outlet pipe 32, so that the resistance of water flow is increased, the voltage shared by the water flow is increased, the voltage of the water flow flowing to the user is reduced, and the safety of the user in the use process is further ensured.

With continued reference to fig. 4 and 5, in some embodiments, the outlet pipe 32 further includes a first communication hole 324 and a second communication hole 325. Wherein, the first communication hole 324 is disposed near the water outlet end of the first water inlet channel 321 and the water inlet end of the first middle channel 322, and is used for communicating the first water inlet channel 321 and the first middle channel 322.
