Example one

The embodiment provides a built-in scale inhibition module 100, and the built-in scale inhibition module 100 is arranged inside an inner container 200 of a water heater and is used for preventing the inner container 200 from scaling, so that the water quality of water in the inner container 200 and the heating efficiency of the water heater are improved, and safety accidents such as heating pipe burst and the like of the heater are avoided. As shown in fig. 1, the built-in scale inhibition module 100 includes a water return frame 1 and a scale inhibition member 2. Specifically, the water returning frame 1 is connected with the water inlet pipe 300, and the specific connection mode is not limited, and the water returning frame may be welded or connected by using a connecting member. The reverse water rack 1 is provided with an accommodating space, the scale inhibition part 2 and the water outlet end of the water inlet pipe 300 are both arranged in the accommodating space, the scale inhibition factor of the scale inhibition part 2 is configured to enter the inner container 200 along with the water flow flowing out of the water inlet pipe 300, and the scale inhibition factor can act with scale forming ions (such as calcium ions, magnesium ions and the like) in water after being diffused into the water to form a stable complex, so that the scale forming ions are prevented from scaling and separating out, and the scale inhibition effect on the water scale inhibition in the inner container 200 is achieved. Optionally, the scale inhibition component 2 may be a scale inhibition filter bag, a scale inhibition filter material is filled in the scale inhibition filter bag, and the scale inhibition filter material can release scale inhibition factors when contacting water. The scale inhibiting filter material is a material that can inhibit scale in the inner container 200, and the scale inhibiting filter material in the present embodiment is suitable for use.

In this embodiment, the reverse water frame 1 is connected to the water inlet pipe 300, so that the built-in scale inhibiting module 100 can be fixed inside the inner container 200, and the installation holes required for fixing the built-in scale inhibiting module 100 can be avoided being formed in the inner container 200, thereby reducing the risk of water leakage of the inner container 200 and being beneficial to improving the use safety of the water heater. And because the water outlet ends of the scale inhibition part 2 and the water inlet pipe 300 are both arranged in the accommodating space, the water flow flowing out of the water inlet pipe 300 can wash the scale inhibition part 2, so that the scale inhibition part 2 is fully contacted with the water flow, thereby fully and quickly releasing scale inhibition factors in the scale inhibition part 2, and being beneficial to improving the scale inhibition effect. In addition, because the scale inhibition member 2 is arranged in the inner container 200, when the water inlet pipe 300 does not enter and the scale inhibition member 2 is still standing, the scale inhibition member 2 can still release scale inhibition factors, which is beneficial to further improving the scale inhibition effect.

Of course, in other embodiments, the water repellent frame 1 may be provided in other shapes, such as a V-shaped frame.

Optionally, when the reverse water frame 1 is placed inside the inner container 200, the reverse water frame 1 is reversely arranged with its top opening facing downward, and the scale inhibiting member 2 is placed below the water inlet pipe 300, so that the water flow flowing out of the water inlet pipe 300 can flow onto the scale inhibiting member 2, and the scale inhibiting member 2 is washed away. At this time, the bottom plate 102 of the inverted water rack 1 can limit the flow direction of water flow, so that more water flow flows to the scale inhibition member 2.

Further, in order to avoid the scale inhibition member 2 from being separated from the top opening of the U-shaped groove under the action of water flow, as shown in fig. 1, the top of each of the first side plate 101 and the second side plate 103 is provided with a folding plate 104, and the folding plates 104 are configured to be capable of folding towards the inside of the U-shaped groove and abutting against the scale inhibition member 2. The number of flaps 104 is not limited and the number of flaps 104 on each side panel may be one, two, three, or more.

One ends of the transverse plate 304 and the two vertical plates 303 are surrounded to form a U-shaped second preformed hole 301, and the second preformed hole 301 is used for avoiding the water inlet pipe 300, so that the water outlet end of the water inlet pipe 300 can enter the water reversing frame 1. The horizontal plate 304 and the other ends of the two vertical plates 303 enclose a U-shaped water passing groove 305, and when the water reversing frame 1 is arranged in an inverted manner, water flow can flow out of the built-in scale inhibition module 100 from the water passing groove 305. Alternatively, the spacing pad 3 is made of an insulating material, such as rubber, plastic, etc.
