The invention provides a water heater.

1 and 2, the water heater 100 includes an inner tank 10 and a pipeline 30 for guiding the water flow in the inner tank 10, the pipeline 30 includes a first pipeline 31 and a second pipeline 33, the first Two pipelines 33 are inserted into the first pipeline 31 and are spaced apart from the first pipeline 31 to jointly form two passages separated by the second pipeline 33 , and the two passages are connected to the inner container 10 connected.

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

In this embodiment, both the first pipe 31 and the second pipe 33 are circular pipes, and the passage between the first pipe 31 and the second pipe 33 is an annular passage. Ensuring the gap size of the annular channel can ensure the passage of water flow.

In this embodiment, the first pipe 31 and the second pipe 33 are vertical pipes, and the top ends thereof communicate with the inner container 10 .

In the water heater 100 provided by the present invention, the first pipe 31 surrounds the second pipe 33 and is spaced apart from the second pipe 33 to form two passages separated by the second pipe 33 , and the two passages The passages are all connected with the inner tank 10 to complete the functions of water outlet and inlet respectively, so that the inner tank 10 only needs to open one interface to complete the function of outlet and water inlet, which reduces the possibility of water leakage of the inner tank 10 and optimizes the The structure of the water heater.

Preferably, the first pipeline 31 includes a first pipeline body 311 having a first port 3111 and a second port 3113, a sealing portion 313, and a valve between the first port 3111 and the second port 3113. The guide tube 315, the first port 3111 communicates with the inner tank 10, the sealing part 313 is used to seal the gap between the second port 3113 and the second pipe 33, the The guide tube 315 is arranged at a preset angle and communicates with the first pipeline 31 .

The gap between the first pipe 31 and the second pipe 33 is sealed by the sealing part 315, so that the water flow in the passage changes the vertical flow direction and enters and exits from the side guide pipe 315, Thereby, a circuit is separated in the double-layer pinch tube, which can independently complete the functions of each channel, and ensure that only one port is needed to be connected with the inner container 10, thereby reducing the possibility of water leakage of the inner container 10.

This solution is only a realization of separating the pipeline from the double-layer pinch, but it does not only protect this realization, as long as it is a means that can achieve this goal, it belongs to the scope of protection of the present invention.

Preferably, the second pipeline 33 includes a second pipeline body 331 having a third port 3311 and a fourth port 3313, and a pipeline connector (not shown), the third port 3311 communicates with the inner tank 10, The pipe joint is disposed at the fourth port 3313 .

By connecting the third port 3311 with the inner tank 10 and the fourth port 3313 with an external pipe through a pipe joint, water supply between the inner tank 10 and other equipment is realized. Generally, the second pipeline 33 directly connected with the inner tank 10 is relatively expensive to manufacture, and the price of using the water heater 10 can be reduced by connecting the pipeline joint with an external pipeline.

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

In this embodiment, the first pipeline 31 is used as a water inlet pipeline, and the second pipeline 33 is used as a water outlet pipeline. The water outlet end of the water outlet pipe is higher than the water inlet end of the water inlet pipe, which can prevent a water level from remaining in the inner tank 10, and prevent the water heater 100 from heating but there is no water in the inner tank 10. The amount of water is the so-called dry burning in daily life.

In addition, when the water is heated, the water with high temperature is on the top, and setting the water outlet end on the top can make the temperature of the water outlet higher, ensuring the water outlet temperature of the water heater 100 .

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 identified during installation. When used as a water inlet pipe, the cold water added to the inner tank 10 can be better heated by the heating device in the inner tank 10 .

Preferably, the guide tube 315 is disposed close to the sealing portion 313 .

After the sealing part 313 seals the gap between the first pipe 31 and the second pipe 33, the water flow will be accumulated between the draft tube 315 and the sealing part 313, which is not conducive to the water heater. The use, and the stains will remain for a long time, affecting the cleanliness of the water flow. Therefore, setting the guide tube 315 close to the sealing portion 313 reduces or even eliminates the area where the water flow accumulates and improves the cleanliness of the water flow.

Preferably, the angle formed by the 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 acted by gravity, the angle formed by the guide tube 315 and the pipe body 311 from the first port 3111 to the second port 3113 is an acute angle, matching the water flow that receives the gravity. The direction can make the water in and out more efficient.

Preferably, at least one of the first pipe 31 and the second pipe 33 is 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, which plays a role in inhibiting and sterilizing bacteria in the first pipeline 31 and the second pipeline 33, The bacteria in the water flow that the user contacts after using the water heater is less, and the satisfaction of the user is improved.

Preferably, an electric heating pipe (not shown) is provided inside the inner container 10 , and the electric heating pipe is arranged at the bottom of the inner container 10 .

Because of the physical characteristics of thermal expansion and contraction, water with high temperature has a large volume and low density, so that the part with the highest temperature of the water is at the top of the water, and the part with the lowest temperature is at the bottom of the water, so it passes through the bottom of the inner tank 10. The electric hot water pipe is set so that an alternating cycle of cold and hot water is formed in the inner tank 10, ensuring that all the water in the inner tank 10 can have a better heating temperature, and the heating of the water heater 100 is improved. performance.

Preferably, the first pipeline 31 includes a first port 3111 extending into the inner tank 10, the second pipeline 33 includes a third port 3311 extending into the inner tank 10, and the first port The level of 3111 is lower than the 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 and affect the water output of the second pipe 33 as the water outlet pipe, the design of the first port 3111 is lower than that of the third port. The port 3311 ensures the normal use of the second pipe 33 as a water outlet pipe.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Under the conception of the present invention, the equivalent structural transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly/indirectly used in Other relevant technical fields are included in the patent protection scope of the present invention.
