The invention provides a water heater.

Referring to fig. 1 and 2, the water heater 100 includes an inner container 10 and a pipeline 30 for guiding water in the inner container 10 to flow in and out, the pipeline 30 includes a first pipeline 31 and a second pipeline 33, the second pipeline 33 is inserted into the first pipeline 31 and is spaced apart from the first pipeline 31, two channels are formed by the second pipeline 33, and both the channels are communicated with the inner container 10.

The first pipe 31 and the second pipe 33 form a double-layer pipe, and two independent channels with the second pipe 33 as a gap are formed, wherein one channel is used as a water inlet channel, and the other channel is used as a water outlet channel.

In this embodiment, the first pipe 31 and the second pipe 33 are both circular pipes, and a passage between the first pipe 31 and the second pipe 33 is an annular passage. The size of the gap of the annular channel is ensured, and the water flow can be ensured to pass through.

In this embodiment, the first pipe 31 and the second pipe 33 are vertical pipes, and the top ends of the first pipe and the second pipe are both communicated with the liner 10.

The water heater 100 provided by the invention surrounds the second pipeline 33 through the first pipeline 31 and is arranged at intervals with the second pipeline 33, two channels which take the second pipeline 33 as intervals are formed together, and the two channels are communicated with the inner container 10 to respectively complete the water outlet and inlet functions, so that the inner container 10 can complete the water outlet and inlet functions only by arranging one interface, the possibility of water leakage of the inner container 10 is reduced, and the structure of the water heater is optimized.

Preferably, the first pipe 31 includes a first pipe body 311 having a first port 3111 and a second port 3113, a sealing portion 313, and a flow guide pipe 315 located between the first port 3111 and the second port 3113, the first port 3111 is communicated with the inner container 10, the sealing portion 313 is used for sealing a gap between the second port 3113 and the second pipe 33, and the flow guide pipe 315 is disposed at a predetermined angle and is communicated with the inside of the first pipe 31.

The sealing part 315 seals the gap between the first pipeline 31 and the second pipeline 33, so that the water flow in the channel changes the vertical flow direction and enters and exits from the flow guide pipe 315 at the side, a line is divided in the double-layer clamping pipe, the function of each channel can be independently completed, only one opening is required for connecting the double-layer clamping pipe with the inner container 10, and the possibility of water leakage of the inner container 10 is reduced.

The scheme is only one implementation mode of separating the pipeline from the double-layer pipe clamp, but the scheme does not only protect the implementation mode, and the method for achieving the purpose belongs to the protection scope of the invention.

Preferably, the second duct 33 includes a second duct body 331 having a third port 3311 communicating with the inner container 10 and a fourth port 3313, and a duct joint (not shown) provided at the fourth port 3313.

The third port 3311 is communicated with the inner container 10, and the fourth port 3313 is communicated with an external pipeline through a pipeline joint, so that the inner container 10 is supplied with water flow with other equipment. The second pipe 33, which is generally in direct communication with the inner container 10, is relatively expensive to manufacture, and the price of the water heater 10 can be reduced by connecting the pipe joint with an external pipe.

Preferably, the level of the first port 3111 is lower than the level of the third port 3311.

In this embodiment, the first pipe 31 serves as an inlet pipe, and the second pipe 33 serves as an outlet pipe. The water outlet end of the water outlet pipe is higher than the water inlet end of the water inlet pipe in horizontal height, so that water with a water level can be prevented from being reserved in the inner container 10, and the situation that the water heater 100 is heated but no water exists in the inner container 10, namely dry burning in daily life, is avoided.

In addition, when water with high temperature is heated, the water outlet end is arranged at the upper part, so that the temperature of the outlet water is higher, and the temperature of the outlet water of the water heater 100 is ensured.

Preferably, the first port 3111 matches the shape of the inner wall of the inner container 10.

By designing the shape of the first port 3111 to match the shape of the inner wall of the liner 10, the installation position can be better found during installation. When the water tank is used as a water inlet pipeline, cold water supplemented to the inner container 10 can be better heated by a heating device in the inner container 10.

Preferably, the flow conduit 315 is disposed proximate to the closure 313.

After the sealing portion 313 seals the gap between the first pipeline 31 and the second pipeline 33, water flow is accumulated between the flow guide tube 315 and the sealing portion 313, which is not beneficial to the use of the water heater, and stains may remain over time, which affects the cleanliness of the water flow. Therefore, the flow guide tube 315 is disposed close to the sealing portion 313, so as to reduce or even eliminate the water flow accumulation area and improve the water flow cleanliness.

Preferably, an angle formed between the flow guide tube 315 and the pipe body 311 from the first port 3111 to the second port 3113 is an acute angle.

Because the water flow is under the action of gravity, the angle formed by the flow guide pipe 315 and the pipe body 311 from the first port 3111 to the second port 3113 is an acute angle, and the water flow direction under the action of gravity is matched, so that the water inlet efficiency and the water outlet efficiency are higher.

Preferably, at least one of the first and second pipes 31 and 33 is internally provided with an antibacterial material layer (not shown).

The inner wall of at least one of the first pipeline 31 and the second pipeline 33 is coated with an antibacterial material layer, and the first pipeline 31 and the second pipeline 33 play roles in bacteriostasis and sterilization, so that the water flow which is contacted with a user after the water heater is used is less in bacteria, and the satisfaction degree of the user is improved.

Preferably, an electric water pipe (not shown) is disposed in the inner container 10, and the electric water pipe is disposed at the bottom of the inner container 10.

Because the water with high physical characteristic temperature of expansion with heat and contraction with cold is large in volume and low in density, the part with the highest water temperature is at the topmost part of the water, and the part with the lowest temperature is at the bottom of the water, the electric heating water pipe is arranged at the bottom of the inner container 10, so that the alternating circulation of cold water and hot water is formed in the inner container 10, the better heating temperature of all the water in the inner container 10 can be ensured, and the heating performance of the water heater 100 is improved.

Preferably, the first pipe 31 includes a first port 3111 extending into the inner container 10, and the second pipe 33 includes a third port 3311 extending into the inner container 10, wherein a level of the first port 3111 is lower than a level of the third port 3311.

In order to avoid the disadvantage that the water flow impact of the first pipe 31 as the water inlet pipe is too large to affect the water outlet amount of the second pipe 33 as the water outlet pipe, the first port 3111 is designed to be lower than the third port 3311, so that the second pipe 33 is ensured to be normally used as the water outlet pipe.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
