[0026] A pipeline machine with a preheating function and a large hot water flow rate provided by the present utility model includes a body 1. Inside the body 1, a water tank 2, a preheating group 6 and a water tank 2 are respectively arranged. A switching valve 5 is arranged on the inner wall above the preheating group 6 of the water tank 2. A water delivery pipeline 4 is connected between the water tank 2, the filter element 3 and the switching valve 5. A water extraction pump 11 is arranged at the bottom of the body 1. A water extraction pipe 10 connected to the water inlet end of the water extraction pump 11 is arranged on the outer wall of the water tank 2. The output end of the water extraction pump 11 is connected to the preheating group 6. The preheating group 6 is connected to the switching valve 5 through a pipeline, and a return pipe 12 is connected between the switching valve 5 and the water tank 2. The preheating group 6 can preheat the water in a cycle, so that the water is hotter faster when receiving hot water through the water outlet nozzle 16, and the water at a high liquid level is preheated, so that the inside of the water tank is full of preheated hot water, and the hot water flow rate is large when discharging hot water.

[0027] When the water in the water tank 2 exceeds the high-level sensor 19, the pumping pump 11 can extract the water inside the water tank 2 through the water extraction pipe 10 into the inside of the preheating group 6 for circulating preheating, realizing the preheating function. When hot water is discharged, the water becomes hot faster, and the water at a high level is preheated, so that the inside of the water tank 2 is full of preheated hot water, making the water flow rate larger when discharging hot water.

[0028] In an embodiment provided by the present utility model, as Figure 2 and Figure 3 shown, a first valve 7 and a second valve 8 are respectively arranged on the outer wall of the water delivery pipe 4, and the first valve 7 is located above the second valve 8. When the first valve 7 is opened and the second valve 8 is closed, water can reach the switching valve 5 through the water delivery pipe 4. When the switching valve 5 switches to the water outlet nozzle 16, water can be discharged through the water outlet nozzle 16. When both the first valve 7 and the second valve 8 are opened, water can enter the inside of the water tank 2 through the water delivery pipe 4.

[0029] In another embodiment provided by the present utility model, as Figure 4 shown, a high-level sensor 19 is arranged on the inner wall of the top of the water tank 2, and a low-level sensor 20 is arranged on the inner wall of the bottom of the water tank 2.

[0030] In still another embodiment provided by the present utility model, as Figure 2 and Figure 3 shown, a water inlet pipe 9 is arranged at the bottom of the machine body 1, and the top end of the water inlet pipe 9 is connected to the filter element 3. Water enters the inside of the filter element 3 through the water inlet pipe 9.

[0031] In an embodiment provided by the present utility model, as Figure 1 shown, an overflow box 13 is arranged on the outer wall of the front side of the machine body 1, and an overflow plate 14 is clamped inside the overflow box 13. A plurality of overflow grooves 15 are formed inside the overflow plate 14. The water overflowing during water receiving flows into the inside of the overflow box 13 through the overflow grooves 15 for temporary storage.

[0032] In another embodiment provided by the present utility model, as Figure 1 shown, a water outlet nozzle 16 is arranged on the outer wall of the front side of the machine body 1, and the water outlet nozzle 16 is connected to the switching valve 5. The water outlet nozzle 16 is used for receiving water.

[0033] In still another embodiment provided by the present utility model, as Figure 1 、 2 and Figure 3As shown, an adjustment knob 17 and a display screen 18 are respectively arranged on the outer wall of the front side of the body 1, and the switching valve 5, the preheating group 6, the first valve 7, the second valve 8, the pumping unit 11, the adjustment knob 17, the high liquid level sensor 19 and the low liquid level sensor 20 are all electrically connected to the display screen 18 through wires.

[0034] Working principle: Water is introduced into the interior of the filter element 3 through the water inlet pipe 9. The filter element 3 filters impurities and alkali in the water, making the taste of the water better and preventing alkali from adhering to the interior of the preheating group 6. By opening the first valve 7 and closing the second valve 8, the filtered water can reach the switching valve 5 through the water delivery pipe 4. The switching valve 5 switches to the water outlet nozzle 16, and the water discharged through the water outlet nozzle 16 is normal temperature water. When the first valve 7 and the second valve 8 are opened, water enters the interior of the water tank 2 through the water delivery pipe 4. When the water in the water tank 2 contacts the high liquid level sensor 19, the pumping unit 11 pumps the water in the water tank 2 into the interior of the preheating group 6 through the water suction pipe 10 for heating. By opening the switching valve 5 to the return pipe 12, the preheated water flows back to the interior of the water tank 2 through the switching valve 5 and the return pipe 12, realizing the preheating function, making the water hotter faster when discharging hot water, and preheating the water at a high liquid level, making the interior of the water tank 2 filled with preheated hot water, so that the water flow is greater when discharging hot water.
