[0037] The present application proposes a water heater, combined with Figures 1 to 6 As shown, in some embodiments, the water heater includes a water inlet connector 100, a water pump 400, a connecting pipe 200 and a shielding member 500. The water inlet connector 100 is provided with a water port 110. The water pump 400 is arranged above the water inlet connector 100, and the water pump 400 is provided with a water pump inlet 401. The shielding member 500 is arranged in front of the water inlet connector 100, so as to shield the water inlet connector 100. When projected along the water heater from top to bottom, the projection of the shielding member 500 is in front of the projection of the water pump inlet 401, and the projection of the water pump inlet 401 is in front of the projection of the water port 110. The connecting pipe 200 is used to connect the water port 110 with the water pump inlet 401, and the connecting pipe 200 is designed to be at least partially bent.

[0038] Specifically, the water inlet connector 100 is a component used to be connected to a tap water pipe through a pipeline. One end of the connecting pipe 200 can be directly or indirectly connected to the water inlet connector 100 to achieve communication between the connecting pipe 200 and the water outlet 110. The other end of the connecting pipe 200 can be directly or indirectly connected to the water pump 400 to achieve communication between the connecting pipe 200 and the water pump inlet 401. Water is output from the tap water pipe and flows through the water inlet connector 100, and then flows along the connecting pipe 200 to the water pump 400, and is pumped by the water pump 400. The water flow is pressurized by the action of the water pump 400.

[0039] Taking the water heater in a normally installed state as a reference, the user stands facing the water heater, the side of the water heater facing the user is the front, the side of the water heater away from the user is the back, the side of the water heater corresponding to the user's left hand is the left, the side of the water heater corresponding to the user's right hand is the right, the side of the water heater close to the ground is the lower (bottom), and the side of the water heater away from the ground is the upper (top).

[0040] The water pump 400 is arranged above the water inlet joint 100, that is, the water pump 400 is closer to the top of the water heater relative to the water inlet joint 100, the water inlet joint 100 is closer to the bottom of the water heater relative to the water pump 400, and the water pump 400 and the water inlet joint 100 are separated by a certain distance in the up-down direction. Projected along the top-down direction, the projection of the water pump inlet 401 is in front of the projection of the water port 110, that is, the water pump inlet 401 is closer to the front side of the water heater relative to the water port 110, and the water port 110 is closer to the back side of the water heater relative to the water pump inlet 401. By such an arrangement, the water port 110 and the water pump inlet 401 are staggered. Under the premise that the water port 110 and the water pump inlet 401 are staggered, at least part of the connecting pipe 200 is designed to be bent, so that the water port 110 and the water pump inlet 401 can be connected.

[0041] Generally speaking, the water heater has a shielding member 500, which is arranged in front of the water inlet connector 100, that is, the shielding member 500 is closer to the front side of the water heater relative to the water inlet connector 100. The shielding member 500 is used to shield the water inlet connector 100. For example, the shielding member 500 shields at least part of the water inlet connector 100 along the direction from front to back of the water heater. There are many types of shielding members 500. The shielding member 500 can be a part of the outer shell 600 of the water heater. The shielding member 500 can also be an exterior decorative member. The shielding member 500 can also include a display screen. In this embodiment, when projected along the top-down direction of the water heater, the projection of the shielding member 500 is in front of the projection of the water pump inlet 401. Since the projection of the water pump inlet 401 is in front of the projection of the water outlet 110, there is a certain distance between the shielding member 500 and the water inlet connector 100. The size of this distance is adapted to the size of the water pump inlet 401, so there is more sufficient space when connecting the water inlet connector 100 with pipes, and the pipe connection operation is not easy to interfere with the shielding member 500.

[0042] In particular, it is particularly suitable for some larger-sized water pumps 400. For example, the water heater includes a shell 600, the water pump 400 is installed on the rear side of the shell 600, and the water pump inlet 401 is located on the front side of the water pump 400 and is relatively close to the front side of the shell 600. If the projection of the water outlet 110 is set in front of or directly below the projection of the water pump inlet 401, this will cause the water inlet connector 100 and the shielding member 500 to be close, which is inconvenient for the water inlet connector 100 to perform pipeline connection operations, or it is necessary to increase the forward movement distance of the shielding member 500, but this will lead to an increase in the space occupied by the water heater and a change in the appearance structure. In this embodiment, through the mutual cooperation of the water inlet connector 100, the water pump 400, the connecting pipe 200 and the shielding member 500, more effective use of space is made, without making too many changes to the appearance structure of the water heater, thereby avoiding an increase in the volume of the water heater and effectively avoiding interference between the water inlet connector 100 and the shielding member 500.

[0043] Combination Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the projection of the water inlet connector 100 is designed to be within the contour range of the projection of the water pump 400, that is, when the water heater is viewed from top to bottom, the water pump 400 completely shields the water inlet connector 100. It can be understood that when the water pump 400 is installed inside the water heater, the water pump 400 already occupies a certain space. Since the water inlet connector 100 is arranged below the water pump 400, in this embodiment, the projection of the water inlet connector 100 is designed to be within the contour range of the projection of the water pump 400, so that the water inlet connector 100 makes full use of the space below the water pump 400, and the structure of the water heater is more compact.

[0044] Combination Figures 4 to 6 As shown, in some embodiments, the axial direction of the water port 110 extends along the up-down direction of the water heater, and the axial direction of the water pump inlet 401 also extends along the up-down direction of the water heater. For example, the axial direction of the water port 110 extends along the up-down direction of the water heater and the water port 110 is open upward, and the axial direction of the water pump inlet 401 extends along the up-down direction of the water heater and the water pump inlet 401 is open downward. By setting it in this way, the bending degree of the connecting pipe 200 can be reduced, thereby reducing the manufacturing difficulty of the connecting pipe 200, and reducing the resistance to the flow of water. It is understandable that if the axial direction of either the water port 110 and the water pump inlet 401 extends in the up-down direction, and the axial direction of the other extends in the left-right direction, then the connecting pipe 200 needs to have a large bend to achieve the connection between the water port 110 and the water pump inlet 401, which not only increases the manufacturing difficulty, but also increases the resistance to the flow of water.

[0045] Combination Figure 6 and Figure 8 As shown, in some embodiments, the connecting pipe 200 includes a first pipe segment 210, a second pipe segment 220 and a third pipe segment 230. The first pipe segment 210 of the connecting pipe 200, the second pipe segment 220 of the connecting pipe 200 and the third pipe segment 230 of the connecting pipe 200 are arranged in sequence. The connecting pipe 200 can be an integrally formed structure to form the first pipe segment 210, the second pipe segment 220 and the third pipe segment 230, or the first pipe segment 210, the second pipe segment 220 and the third pipe segment 230 are independent components and are connected together by connecting means to form the connecting pipe 200.

[0046] The first pipe section 210 is disposed at one end of the second pipe section 220, and the first pipe section 210 is bent relative to the second pipe section 220. The third pipe section 230 is disposed at the other end of the second pipe section 220, and the third pipe section 230 is bent relative to the second pipe section 220. For example, the first pipe section 210 of the connecting pipe 200, the second pipe section 220 of the connecting pipe 200, and the third pipe section 230 of the connecting pipe 200 are sequentially disposed along the direction of the water flow, and the water flows sequentially along the first pipe section 210, the second pipe section 220, and the third pipe section 230. The connecting pipe 200 is connected to the water port 110 through the first pipe section 210, and the connecting pipe 200 is connected to the water pump inlet 401 through the third pipe section 230. In particular, the connecting pipe 200 can be designed as a hard pipe, so that it has a higher structural strength even under the premise that the connecting pipe 200 is bent. Compared with a soft pipe, a hard pipe is more resistant to water pressure and is not easy to break, thereby improving the service life of the connecting pipe 200.

[0047] In this embodiment, the bending direction of the first pipe segment 210 relative to the second pipe segment 220 is opposite to the bending direction of the third pipe segment 230 relative to the second pipe segment 220. In this way, the length of the connecting pipe 200 can be further shortened while achieving the connection between the water inlet 110 and the water pump inlet 401, thereby reducing material costs.

[0048] Combination Figure 5 As shown, in some embodiments, the water heater also includes a water flow control component 300, and the water flow control component 300 has a water inlet 311 and a water outlet 312. One end of the connecting pipe 200 is connected to the water inlet joint 100, and the other end of the connecting pipe 200 is connected to the water flow control component 300, thereby realizing the connection between the water port 110 and the water inlet 311, and the water flow control component 300 is connected to the water pump 400, thereby realizing the connection between the water outlet 312 and the water pump inlet 401.

[0049] Specifically, the water flow control component 300 is a component used to control and / or sense the water flow. For example, the water flow control component 300 is used to sense the water flow and generate a signal, and the water heater controls the firepower of the water heater according to the signal fed back by the water flow control component 300. For another example, the water flow control component 300 is used to control the water flow, and the water heater can adjust the water flow through the water flow control component 300 according to the actual operating conditions. The water flow control component 300 can refer to the relevant technology and is not described in detail here. Since the water pump 400 is arranged above the water inlet connector 100, there is enough space between the water pump 400 and the water inlet connector 100 for installing the water flow control component 300, thereby improving the utilization of space.

[0050] It is understandable that there are many ways to connect the water inlet connector 100 with the connecting pipe 200, the connecting pipe 200 with the water flow control component 300, and the water flow control component 300 with the water pump 400, as long as the water path can be connected. For example, the water inlet connector 100 is plug-connected with the connecting pipe 200 to achieve the connection between the water port 110 and the connecting pipe 200, the connecting pipe 200 is plug-connected with the water flow control component 300 to achieve the connection between the connecting pipe 200 and the water inlet 311, and the water flow control component 300 is plug-connected with the water pump 400 to achieve the connection between the water outlet 312 and the water pump inlet 401.

[0051] Combination Figure 4 and Figure 5As shown, in some embodiments, the water flow control component 300 includes a channel portion 310 and a valve portion 320. The channel portion 310 is provided with a water inlet 311 and a water outlet 312. Water flows into the channel portion 310 from the water inlet 311 and flows out from the water outlet 312. For example, water flows into the connecting pipe 200 from the water inlet joint 100, and then enters the channel portion 310 from the connecting pipe 200 through the water inlet 311, and then flows out of the channel portion 310 from the water outlet 312 and enters the water pump 400. The valve portion 320 is installed on the channel portion 310, and the valve portion 320 cooperates with the channel portion 310. The valve portion 320 is used to control the flow area of ​​the channel portion 310. Through the action of the valve portion 320, the size of the water flow can be adjusted. The valve portion 320 is perpendicular to the channel portion 310, forming a T-shaped structure. In order to make the water flow control component 300 use space more reasonably, in this embodiment, the channel portion 310 and the water pump 400 surround a clamping cavity 330. Figure 4 As shown, the axial direction of the water pump inlet 401 extends in the up-down direction, the channel portion 310 needs to be connected to the water pump inlet 401, and the channel portion 310 extends downward relative to the water pump 400, so that a clamping cavity 330 is formed behind the channel portion 310 and below the water pump 400, and the valve portion 320 is arranged in the clamping cavity 330 to make full use of this space.

[0052] Combination Figures 4 to 6 As shown, in some embodiments, the axial direction of the water inlet 311, the axial direction of the water outlet 312, and the axial direction of the water pump inlet 401 are designed to extend in the up-down direction of the water heater, respectively. Since the water flow control component 300 is connected to the water pump 400 to achieve the communication between the water outlet 312 and the water pump inlet 401, the axial direction of the water outlet 312 and the axial direction of the water pump inlet 401 are designed to extend in the up-down direction, which can reduce the difficulty of connecting the water flow control component 300 and the water pump 400.

[0053] For example, when the axial direction of the water outlet 312 and the axial direction of the water pump inlet 401 are designed to extend in the up-down direction, the two can be connected by plugging, which is more convenient and quick. Since the water flows into the water flow control component 300 from the water inlet 311 and flows out of the water flow control component 300 from the water outlet 312, the axial direction of the water inlet 311 and the axial direction of the water outlet 312 are designed to extend in the up-down direction, thereby reducing the flow resistance in the water flow control component 300. Furthermore, the water pump inlet 401, the water outlet 312 and the water inlet 311 can be designed to be coaxially arranged, thereby further reducing the length of the waterway, thereby reducing the resistance of the water flow.

[0054] Combination Figure 3 and Fig. 9As shown, in some embodiments, the water pump 400 includes a first impeller 410 and a second impeller 420, the first impeller 410 is located upstream of the second impeller 420, and the first impeller 410 and the second impeller 420 are coaxially arranged. When the water pump 400 is working, water flows into the water pump from the water pump inlet 401, and passes through the first impeller 410 and the second impeller 420 in turn. Compared with a single-stage impeller, the first impeller 410 and the second impeller 420 in this embodiment greatly increase the pressure of the water flow, which is particularly suitable for old household water networks. Since the first impeller 410 is coaxial with the second impeller 420, the size of the water pump 400 is much larger along the extension direction of the rotation axis of the water pump 400 relative to a single-stage impeller. In the present embodiment, the rotation axis of the water pump 400 is designed to extend along the front-to-back direction. For example, the water pump 400 is installed on the back side of the water heater, and the water pump inlet 401 is arranged on the front side of the water pump 400. By arranging the water inlet connector 100 below the water pump 400 and in a relatively rearward position, a certain distance is created between the water inlet connector 100 and the shielding member 500, thereby fully utilizing the space and preventing interference between the water inlet connector 100 and the shielding member 500.

[0055] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made based on the concept of the present application and the contents of the present application description and drawings, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
