Description

储水式热水器及其进水管Water storage water heater and its water inlet pipe

技术领域 technical field

本实用新型涉及热水器领域,具体而言,涉及一种储水式热水器及其进水管。  The utility model relates to the field of water heaters, in particular to a water storage type water heater and a water inlet pipe thereof. the

背景技术 Background technique

现在热水器使用的很多进水管都采用了一定的缓冲水流的结构,如采用反向改变水流方向来控制水流出的速度和压力,使冷水集中在热水器内胆底部,这样可以减轻底部冷水与热水器内胆内已经加热好的热水之间的混合,尽可能少的吸收热水器的热量,尽可能少的降低内胆内的温度。如图1所示,现有技术中一般采用的都是中间水管10放置于外层套管20的中心,中间水管和外层套管具有均匀的间隙30,进水管通过固定装置40固定在热水器内胆上,冷水沿S1所示方向进入进水管,沿S2方向流出。由于中间水管10与外层套管20同心安装,这样就导致,要么为保证中间水管和外层套管的间隙30合适,外层套管直径较大,影响进水管安装,导致内胆连接管较大,提高了成本,影响了生产工艺,比如焊接等等;要么为保证进水管安装,中间水管和外层套管间隙尽管均匀,但是间隙较小,而较小的间隙,会导致当水质不好的时候,使用时间稍长,水管的间隙被水垢堵上的情况,导致出水困难、甚至不出水的问题。  Many water inlet pipes used in water heaters now use a certain structure to buffer water flow, such as changing the direction of water flow in reverse to control the speed and pressure of water outflow, so that cold water is concentrated at the bottom of the water heater inner tank, which can reduce the cold water at the bottom and the inside of the water heater. The mixing of the hot water that has been heated in the tank absorbs the heat of the water heater as little as possible, and reduces the temperature in the tank as little as possible. As shown in Fig. 1, in the prior art, the middle water pipe 10 is generally placed in the center of the outer casing 20, the middle water pipe and the outer casing have a uniform gap 30, and the water inlet pipe is fixed on the water heater through a fixing device 40 On the inner tank, cold water enters the water inlet pipe along the direction shown by S1, and flows out along the direction S2. Since the middle water pipe 10 and the outer casing 20 are installed concentrically, this leads to either, in order to ensure that the gap 30 between the middle water pipe and the outer casing is suitable, the diameter of the outer casing is relatively large, which affects the installation of the water inlet pipe and causes the inner tank connecting pipe Larger, which increases the cost and affects the production process, such as welding, etc.; or to ensure the installation of the water inlet pipe, although the gap between the middle water pipe and the outer casing is uniform, the gap is small, and the small gap will lead to poor water quality. When it is not good, the use time is a little longer, and the gaps in the water pipes are blocked by scale, which makes it difficult to get water out, or even out of water. the
