[0027] During operation, the water to be purified first enters the preheating channel of the dual-channel instant heating module 1 for preheating, and then enters the reverse osmosis filter element 2, thereby effectively avoiding the problem of low reverse osmosis water production under low-temperature water, increasing the temperature of the water before the reverse osmosis membrane, and thus increasing the water production rate of the reverse osmosis water purifier.
[0028] The instant reverse osmosis water purifier provided in this embodiment also includes a pre-filter element 4 and a post-filter element 5, which are respectively connected to the water inlet and outlet ends of the reverse osmosis filter element 2 to achieve pre-filtration and post-filtration. The water filtered by the post-filter element 5 enters the heat exchanger 3 or the instant hot runner. The normal temperature water pipeline 8 is connected to the water outlet end of the post-filter element 5 to take out normal temperature purified water. The normal temperature water pipeline 8 is connected to a pipeline machine 11 and is connected to a water tap 10 through a normal temperature water pipeline valve 12 to meet different normal temperature water intake requirements.
[0029] In this embodiment, a water inlet on-off valve 13 is preferably connected between the pre-filter element 4 and the reverse osmosis filter element 2, a check valve 14 and a high-pressure switch 15 are preferably provided between the reverse osmosis filter element 2 and the post-filter element 5, and a water pump 16 and a flow meter 17 are preferably connected between the post-filter element 5 and the heat exchanger 3. It should be noted that the specific model selection and control circuit design of the normal temperature water pipeline valve 12, the water inlet on-off valve 13, the check valve 14, the high-pressure switch 15, the water pump 16 and the flow meter 17 are all common technical knowledge mastered by those skilled in the art, and will not be described in detail here.
[0030] Furthermore, a booster pump 6 is connected to the water inlet end of the reverse osmosis filter element 2, and a pressure relief valve 7 is connected between the water outlet end of the reverse osmosis filter element 2 and the water inlet end of the booster pump 6. Here, the benefit of providing the booster pump 6 is that the water outlet pressure of the water purifier can be increased, thereby improving the water outlet efficiency.
[0031] Reference Figure 2 , Figure 3 As shown, the dual-channel instant heating module 1 in this embodiment includes a heating plate 1-1 and a flow channel plate 1-2 assembled together, and the heating plate 1-1 and the flow channel plate 1-2 together form an instant hot flow channel 1-3, and a preheating flow channel 1-4 separated from the instant hot flow channel 1-3 is provided in the instant hot flow channel 1-3, and the heating plate 1-1 directly heats the instant hot flow channel 1-3, and the preheating flow channel 1-4 is heated by the liquid in the instant hot flow channel 1-3.
[0032] In this embodiment, the heating plate 1-1 is preferably a rare earth thick film electric heating plate, including a metal substrate and a rare earth thick film resistor circuit arranged on the metal substrate. Obviously, those skilled in the art may use other types of heating plates that are currently known or will be realized in the future according to different actual needs, as long as they can heat the fluid.
[0033] In this embodiment, the cross-section of the instant hot runner 1-3 is preferably trapezoidal, the cross-section of the preheating runner 1-4 is preferably circular, and the cross-sectional area of the instant hot runner 1-3 is larger than the cross-sectional area of the preheating runner 1-4; in this way, preheating is achieved under the premise of maximizing the instant heating effect. Obviously, the cross-sectional shape of the instant hot runner 1-3 and the cross-sectional shape of the preheating runner 1-4 can be appropriately adjusted according to different actual needs, such as setting the cross-sectional shape of the instant hot runner to a semicircular or semi-elliptical shape, and setting the cross-sectional shape of the preheating runner to an elliptical or polygonal shape, etc.; it is not limited to this embodiment.
[0034] In this embodiment, it is preferred that the water inlet and outlet joints of the hot runner 1-3 and the preheating runner 1-4 are located on the same side of the heating plate 1-1, and the water inlet joint of the hot runner 1-3 is arranged close to the water inlet joint of the preheating runner 1-4, and the water outlet joint of the hot runner 1-3 is arranged close to the water outlet joint of the preheating runner 1-4. In this way, the water flow directions of the hot runner 1-3 and the preheating runner 1-4 are the same, which effectively reduces the impact of the fluid preheating of the preheating runner 1-4 on the instant heating temperature of the hot runner 1-3. In some embodiments, the water flow directions of the hot runner 1-3 and the preheating runner 1-4 can be set to be opposite, not limited to this embodiment.
[0035] In some embodiments, the instant heating channels 1-3 and the preheating channels 1-4 can be changed to a flat-laid or vertically stacked design, as long as they can achieve the heat exchange, preheating and instant heating effects.
[0036] In some embodiments, a third flow channel, a fourth flow channel, etc. for preheating or instant heating may also be provided; this is not limited to the present embodiment. Example 2
