Referring to fig. 1 to 4, an embodiment of the present invention provides a water heater, including: a liner unit for storing water, a water outlet pipe 400 for outputting water to the outside of the liner unit, and a water inlet pipe 300 for inputting water to the inside of the liner unit.

Wherein the inner container unit includes: an upper inner container 100 and a lower inner container 200 positioned below the upper inner container 100. The upper inner container 100 and the lower inner container 200 are communicated through a communication passage 500. A flow guide part 600 is further provided inside the upper inner container 100. The guide portion 600 blocks the downstream of the communication passage 500 in the water flow direction.

The water heater that this embodiment provided is through setting up the intercommunication passageway 500 with last inner bag 100 and lower inner bag 200 intercommunication, and then cold water is carried out the choked flow by water conservancy diversion portion 600 when getting into upper inner bag 100 through intercommunication passageway 500, avoids cold water direct impact to be located the hot water layer of inner bag 100 top, reduces the vortex influence that cold water got into upper inner bag 100 and brought. Therefore, the water heater of the embodiment can improve the hot water yield.

In this embodiment, the water heater is an electric water heater, and a heating rod can be inserted into the inner container unit to heat water. The upper liner 100 and the lower liner 200 are arranged in parallel along an axial direction F1. The upper liner 100 and the lower liner 200 are both cylindrical structures, and the axial direction F1 can be understood as the length direction of the upper liner 100 or the lower liner 200. In the axial direction F1, the upper liner 100 has end caps at both ends thereof, and correspondingly, the lower liner 200 has end caps at both ends thereof. The communication passage 500 is located between the upper inner container 100 and the lower inner container 200. The guide portion 600 is shielded above the communication passage 500.

Specifically, a lower connecting hole is formed at the bottom of the upper liner 100, correspondingly, an upper connecting hole is formed at the top of the lower liner 200, and two ends of the connecting pipe 501 are respectively and fixedly connected with the upper connecting hole and the lower connecting hole. The inside of the connection pipe 501 forms a communication passage 500. The communication passage 500 extends in parallel with the vertical direction. One or more communication channels 500 may be provided, and the present application is not limited thereto. The annular space between the inner wall of the connection pipe 501 and the outer wall of the outlet pipe 400 forms a water flow passage. The flow guide part 600 blocks the water flowing out of the water flow passage and guides the water to the peripheral side.

In the present embodiment, the communication passage 500 has one. The water outlet pipe 400 passes through the communication channel 500 and is introduced into the upper liner 100. The water outlet pipe 400 is installed on the bottom wall of the lower inner container 200 and extends upward until passing through the connection passage between the upper inner container 100 and the lower inner container 200. The upper end of the outlet pipe 400 is formed with a water inlet end for inputting hot water. The water outlet end of the water outlet pipe 400 is positioned outside the lower inner container 200, and then outputs hot water to the outside of the water heater.

In this embodiment, the flow guiding portion 600 may change a flow direction of the water output from the communication channel 500, so as to reduce a turbulent influence of the water on the inside of the upper inner container 100. Preferably, the flow guiding portion 600 can guide the water output from the communication channel 500 to the peripheral side, so as to prevent the input water from affecting the upper hot water layer. Specifically, the diversion part 600 may be a water baffle structure or a water baffle structure. The guide part 600 shields the downstream of the water flow direction in the communication channel 500, forms a flow blocking to the cold water entering the upper inner container 100, reduces the flow disturbing capacity of the cold water in the upper inner container 100, thereby reducing the influence of the cold and hot water layers by the flow disturbance, and reducing the influence on the hot water yield. As shown in fig. 1, 2, and 3, the flow guide part 600 is shielded right above the communication channel 500 along the length direction (generally, the vertical direction) of the water outlet pipe 400. The diversion part 600 is fixed on the wall of the water outlet pipe 400.

In other embodiments, as shown in fig. 7, the water outlet pipe 400 passes through the end cap of the upper inner container 100 and enters the upper inner container 100. The water outlet pipe 400 extends into the upper liner 100 through the end cover of the upper liner 100, so that the installation part of the water outlet pipe 400 can be prevented from being additionally arranged on the lower liner 200. In this embodiment, the guide part 600 is fixed to the wall of the upper inner container 100. Specifically, the guiding portion 600 is a guiding cover, the guiding cover is covered on the upper opening of the communicating channel 500, and a plurality of guiding holes 610 facing the end cover of the upper liner 100 are formed in the guiding cover, so that the water flow is guided in the axial direction F1, and the water flow is prevented from upwardly disturbing the hot water layer.

With reference to fig. 1 to 4, in the present embodiment, the water inlet pipe 300 is disposed in the lower liner 200, so that the communication position between the upper liner 100 and the lower liner 200 can be reduced, and only one communication channel 500 is disposed between the upper liner 100 and the lower liner 200, thereby reducing the welding position and improving the overall structural strength. The water inlet pipe 300 feeds water into the lower inner container 200, and the cold water enters the lower inner container 200 and enters the upper inner container 100 through the communication channel 500 or pushes the water in the lower inner container 200 to enter the upper inner container 100.

In order to have a better flow-blocking guiding effect and reduce the influence on the hot water layer, the flow guide part 600 is located below the middle position of the upper liner 100 in the height direction. Specifically, the flow guide part 600 is 5-50mm higher than the bottom wall of the upper liner 100. As shown in FIG. 3, the distance between the lower end of the diversion part 600 and the bottom wall of the upper liner 100 is L, wherein L is more than or equal to 50mm and more than or equal to 5 mm. Preferably, the flow guide part 600 is 20-30mm higher than the bottom wall of the upper liner 100. For example, the diversion part 600 is 23mm or 25 mm higher than the bottom wall of the upper liner 100.

In this embodiment, the diversion part 600 is fixedly sleeved on the outer wall of the water outlet pipe 400. Specifically, the flow guide part 600 may be welded to the outer wall of the water outlet pipe 400, thereby forming a stable flow guide structure. Further, in order to guide the water flowing out from the communication channel 500 in all directions and reduce the influence on the hot water layer above, a projection of the flow guide portion 600 on a plane (for example, the plane may be a horizontal plane) perpendicular to the water outlet pipe 400 along the extending direction of the water outlet pipe 400 is in a circular ring shape. The diversion part 600 can be fixedly sleeved in a water retaining cap shape on the outer wall of the water outlet pipe 400, the orthographic projection of the diversion part on the horizontal plane is in a ring shape, and then the water flow input by the communicating channel 500 can be guided in all directions in the circumferential direction, so that the influence on the upper hot water layer is reduced.

In other embodiments, the diversion part 600 is not limited to the water blocking cap or the water blocking cover structure, for example, the diversion part 600 may fix a circular plate structure sleeved on the outer wall of the outlet pipe 400.

In the embodiment of the present application, the diversion part 600 may completely shield the communication channel 500, and further may completely block the diversion of the outlet water of the communication channel 500. Wherein the outer diameter of the guide part 600 is larger than the inner diameter of the communication passage 500. For convenient installation, the outer diameter of the flow guide part 600 is 1.2 times the inner diameter of the communication passage 500.

Further, in order to prevent the flow guide part 600 from being deformed when the water outlet pipe 400 carrying the flow guide part 600 is installed, the outer diameter of the flow guide part 600 may be set below the inner diameter of the communication channel 500. To avoid the presence of upward flowing water flow, the outer diameter of the flow guide 600 is more than 0.9 times the inner diameter of the communication passage 500. Therefore, when in assembly, the flow guide part 600 and the water outlet pipe 400 can be assembled firstly, then the water outlet pipe 400 extends into the lower inner container 200 from the mounting hole, and the flow guide part 600 is carried to pass through the communicating channel 500 and then is mounted on the bottom wall of the lower inner container 200.

Specifically, the flow guiding portion 600 includes a flow guiding wall 601 sleeved outside the water outlet pipe 400. The flow guide wall 601 is provided with flow guide holes 610. A water inlet space is formed between the guide wall 601 and the outer wall of the water outlet pipe 400. The top of the water inlet space is the top wall of the water retaining cap, and the top wall is a closed plate body and is not provided with a through hole. The water flow outputted from the communication channel 500 is blocked by the top wall of the water blocking cap and then changes its flow direction to flow out through the diversion hole 610. To avoid guiding the wall of the upper liner 100, the guiding hole 610 faces at least one end of the upper liner 100 along the axial direction F1. Preferably, the plurality of guide holes 610 are distributed on both sides of the guide wall 601 in the axial direction F1. Wherein, a part of the number of the guiding holes 610 faces the end cap at one end of the upper liner 100, and another part of the number of the guiding holes 610 faces the end cap at the other end of the upper liner 100.

In order to reduce the influence on the upper hot water layer, the guiding holes 610 are oriented in a horizontal direction or in a diagonally downward direction. In the present embodiment, the guide holes 610 face the left or right side in the horizontal direction when facing fig. 5. The shape of the deflector hole 610 may be various, such as a circular hole, a square hole, or even an irregular hole. The water blocking cap in fig. 4 is provided with a plurality of circular diversion holes 610. In the embodiment shown in fig. 5 and 6, the diversion hole 610 is a long hole extending in the circumferential direction.

Further, in order to facilitate the installation of the flow guide part 600 through the communication channel 500, a tapered structure 602 is disposed above the flow guide wall 601. The tapered structure 602 has a gradually decreasing outer diameter from bottom to top. The conical structure 602 is not provided with a through hole structure, and the upper end of the conical structure 602 is a closed top wall. The water flow below enters the water inlet space and impacts the conical structure 602 to be buffered and then flows out through the flow guide holes 610 below the conical structure 602, so that the impact force of the water flow is reduced, and the phenomenon that the impact force is too large to cause large turbulence when the water flow flows out through the flow guide holes 610 is avoided.

As shown in fig. 5, in order to avoid the tumbling turbulence caused by the water flow being guided to the adjacent liner walls (two liner walls of the upper liner 100 along the direction F2 in fig. 2, the direction F2 is perpendicular to the direction F1), the flow guide wall 601 has non-porous side walls 630 opposite to the inner wall of the upper liner 100 on two sides of the horizontal direction perpendicular to the axial direction F1 of the upper liner 100. The imperforate side wall 630 is a partial side wall of the deflector cap (deflector 600) facing the liner wall of the liner in the direction of F2 of the liner.

In other embodiments, to provide a better flow guiding effect, the outer diameter of the flow guiding portion 600 may be larger than the inner diameter of the communicating channel 500, and at this time, the flow guiding portion 600 may be an elastic structure that allows a certain elastic deformation and can be restored by itself. When the guide part 600 is assembled, the guide part 600 is contracted to a certain extent when passing through the communicating channel 500, and is expanded and restored after passing through the communicating channel 500, so that the communicating channel 500 is shielded.

As shown in fig. 6, in order to make the flow guide part 600 have certain elasticity to pass through the communication channel 500, the flow guide wall 601 is further provided with a gathering notch 640. The gathering notch 640 extends upward from the lower end of the baffle 601. The closing notch 640 forms an opening on the lower end surface of the guide wall 601, and extends upward from the opening to open the plurality of long hole-shaped guide holes 610. The furling break 640 is located below the conical structure 602. The flow guide part 600 is uniformly distributed with a plurality of folding notches 640 in the circumferential direction. In the case that the folding gap 640 exists, the outer diameter of the flow guide part 600 may be larger than that of the communication passage 500, and the flow guide wall 601 may radially contract through the communication passage 500 when the flow guide part 600 passes through the communication passage 500, and shield the communication passage 500 from flow by post-expansion restoration.
