所述第一管道31和第二管道33形成双层夹管，并形成以所述第二管道33为间隙的两个独立地通道，其中一个作为进水通道，另一个作为出水通道。The first duct 31 and the second duct 33 form a double-layer pinch tube and form two independent passages with the second duct 33 as a gap, one of which serves as a water inlet passage and the other serves as a water outlet passage.

本实施例中，所述第一管道31和所述第二管道33均为圆形管道，所述第一管道31和所述第二管道33之间的通道为环形通道。保证所述环形通道的间隙大小，可以保证水流的通过。In this embodiment, the first duct 31 and the second duct 33 are both circular ducts, and the passage between the first duct 31 and the second duct 33 is an annular passage. The gap size of the annular passage is ensured to ensure the passage of water flow.

本实施例中，所述第一管道31和所述第二管道33为竖直的管道，顶端均与所述内胆10连通。In this embodiment, the first duct 31 and the second duct 33 are vertical ducts, and the top ends are all in communication with the inner tank 10.

通过将所述第三端口3311与所述内胆10连通，所述第四端口3313通过管道接头与外接管道进行连通，实现所述内胆10与其他设备进行水流供给。一般与所述内胆10进行直接连通的所述第二管道33造价比较贵，通过所述管道接头与外界管道连接可以降低所述热水器10使用的价格。By communicating the third port 3311 with the inner tank 10, the fourth port 3313 communicates with an external pipe through a pipe joint to realize water supply of the inner tank 10 and other equipment. The second conduit 33, which is generally in direct communication with the bladder 10, is relatively expensive to manufacture, and the price of the water heater 10 can be reduced by connecting the conduit joint to an external conduit.

优选地，所述第一端口3111的水平高度低于所述第三端口3311的水平高度。Preferably, the level of the first port 3111 is lower than the level of the third port 3311.

本实施例中，所述第一管道31作为进水管道，所述第二管道33作为出水管道。所述出水管道的出水端水平高度高于所述进水管道的进水端，能够防止所述内胆10内存留有一水位的水量，避免所述热水器100在加热但是所述内胆10内没有水量的情况，即日常生活中所说的干烧。In this embodiment, the first pipe 31 serves as a water inlet pipe, and the second pipe 33 serves as a water outlet pipe. The water outlet end of the water outlet pipe is higher than the water inlet end of the water inlet pipe, and the water volume of the water tank 100 can be prevented from remaining in the water tank 100, so that the water heater 100 is not heated but the inner tank 10 is not The amount of water, that is, the dry burning mentioned in daily life.

此外，加热水时温度高的水在上，将所述出水端设置在上可以使出水的温度更高，保证了所述热水器100的出水温度。In addition, when the water is heated, the water having a high temperature is placed on the upper side, and the water outlet end is placed on the water to make the temperature of the effluent higher, thereby ensuring the water discharge temperature of the water heater 100.

优选地，所述第一端口3111与所述内胆10内壁的形状相匹配。Preferably, the first port 3111 matches the shape of the inner wall of the inner liner 10.

通过将所述第一端口3111的形状设计成与所述内胆10内壁的形状相匹配，使得在安装时能够更好地找准安装位置。在作为进水管道时，补充至所述内胆10的冷水能够更好地被所述内胆10中的加热装置进行加热。By designing the shape of the first port 3111 to match the shape of the inner wall of the inner casing 10, the mounting position can be better aligned at the time of installation. When used as a water inlet pipe, the cold water replenished to the inner liner 10 can be better heated by the heating means in the inner casing 10.

优选地，所述导流管315靠近所述封合部313设置。Preferably, the draft tube 315 is disposed adjacent to the sealing portion 313.

所述封合部313封合所述第一管道31和所述第二管道33之间的间隙后，水流会囤积在所述导流管315和所述封合部313之间，不利于热水器的使用，且日久会存留污渍，影响水流的干净度。因此，将所述导流管315靠近所述封合部313设置，减少甚至消除水流囤积的区域，提高水流的干净度。After the sealing portion 313 seals the gap between the first pipe 31 and the second pipe 33, water flow is accumulated between the draft pipe 315 and the sealing portion 313, which is disadvantageous for the water heater. The use of, and will retain stains over time, affecting the cleanliness of the water flow. Therefore, the draft tube 315 is disposed close to the sealing portion 313, thereby reducing or even eliminating the area where the water is accumulated, thereby improving the cleanliness of the water flow.

优选地，所述导流管315与所述管道本体311自所述第一端口3111至所述第二端口3113方向形成的角度为锐角。Preferably, the angle between the draft tube 315 and the pipe body 311 from the first port 3111 to the second port 3113 is an acute angle.

因为水流是受重力作用的，因此所述导流管315与所述管道本体311自所述第一端口3111至所述第二端口3113方向形成的角度为锐角，配合收到重力作用的水流的方向，能够使得进、出水的效率更高。Because the water flow is subjected to gravity, the angle between the draft tube 315 and the pipe body 311 from the first port 3111 to the second port 3113 is an acute angle, and the water flow receiving gravity is used. The direction can make the efficiency of entering and leaving water higher.

优选地，所述第一管道31和所述第二管道33中至少一个内部设有抗菌材料层（未图示）。Preferably, at least one of the first duct 31 and the second duct 33 is internally provided with an antibacterial material layer (not shown).

The user is less likely to have bacteria in the water flow after using the water heater, thereby improving user satisfaction.

优选地，所述内胆10内设有电热水管（未图示），所述电热水管设置于所述内胆10的底部。Preferably, an electric hot water pipe (not shown) is disposed in the inner casing 10, and the electric hot water pipe is disposed at the bottom of the inner casing 10.

因为热胀冷缩的物理特性温度高的水体积大，密度小，使得水温度最高的部分是在水的最顶部、温度最低的部分在水的底部，因此通过在所述内胆10的底部设置所述电热水管，使得在所述内胆10中形成一个冷热水的交替循环，保证所述内胆10中全部的水都能够有更好的加热温度，提高了所述热水器100的加热性能。Because of the physical characteristics of the thermal expansion and contraction, the water having a high temperature and a small density make the water temperature the highest part at the top of the water and the lowest temperature part at the bottom of the water, thus passing through the bottom of the inner tank 10 The electric hot water pipe is arranged such that an alternating circulation of hot and cold water is formed in the inner tank 10 to ensure 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.

优选地，所述第一管道31包括伸入所述内胆10内的第一端口3111，所述第二管道33包括伸入所述内胆10内的第三端口3311，所述第一端口3111的水平高度低于所述第三端口3311的水平高度。Preferably, the first duct 31 includes a first port 3111 extending into the inner casing 10, and the second duct 33 includes a third port 3311 extending into the inner casing 10, the first port The level of 3111 is lower than the level of the third port 3311.

为了避免在所述第一管道31在作为进水管道的水流冲击量过大而影响所述第二管道33作为出水管道出水量的弊端，将所述第一端口3111设计低于所述第三端口3311，确保了所述第二管道33作为出水管道的正常使用。In order to avoid the disadvantage that the first pipe 31 has an excessive impact on the water flow as the water inlet pipe and affect the water output of the second pipe 33 as the water outlet pipe, the first port 3111 is designed to be lower than the third pipe. Port 3311 ensures the normal use of the second conduit 33 as a water outlet conduit.
