DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 5As shown, a pipeline machine of the utility model comprises: a water tank 1, which has a length direction L, a width direction W and a height direction H; a water inlet pipe 2, one end of which is used to connect to a water source, and a first channel 4 is provided between the water inlet pipe 2 and the upper end of the water tank 1 along the height direction H, for supplying water to the water tank 1; a water outlet 3, which is provided on one side of the water tank 1, and a second channel 5 is provided between the water outlet 3 and the water inlet pipe 2, for providing normal temperature water to the water outlet 3, and an end of the first channel 4 away from the water tank 1 and an end of the second channel 5 away from the water outlet 3 Connected; a heating module 9, which is arranged on one side of the water tank 1, and a third channel 6 and a fourth channel 7 are arranged between the heating module 9 and the water tank 1, the third channel 6 is used to extract the water stored in the water tank 1 to heat it in the heating module 9, and the fourth channel 7 is used to introduce the water heated by the heating module 9 into the water tank 1, so as to keep the water stored in the water tank 1 at a predetermined temperature, and a fifth channel 8 is arranged between the heating module 9 and the water outlet 3, and the fifth channel 8 is used to provide the water in the water tank 1 or the water heated to a preset temperature to the water outlet 3.

[0026] When in use, the water inlet pipe 2 is connected to the water source to replenish water in the water tank 1. The first channel 4, the third channel 6 and the fourth channel 7 are opened. While the water tank 1 is replenished, the heating module 9 extracts water from the water tank 1 for heating, and then guides the water heated to the predetermined temperature back to the water tank 1, so that the drinking water in the water tank 1 is maintained at the predetermined temperature. When the required water temperature is normal temperature water, the second channel 5 is opened, and the water introduced by the water inlet pipe 2 flows directly out of the water outlet 3 after passing through the second channel 5. When the required water temperature is exactly the set temperature in the water tank 1, the third channel 6 and the fifth channel 8 are opened, and the heating module 9 directly extracts water from the water tank 1 and discharges it from the water outlet 3. For example, if the preset water temperature in the water tank 1 is 45°C, when the required water temperature is also 45°C, the third channel 6 and the fifth channel 8 are opened, and the water in the water tank 1 flows directly out of the water outlet 3 (at this time, the heating module 9 does not heat the water). When the required water temperature exceeds 45°C (such as 55°C, 80°C or 95°C), the water flowing into the heating module 9 from the third channel 6 will be heated by the heating module 9 first, and then flow out from the water outlet 3.

[0027] In this solution, the third channel 6 and the fourth channel 7 connecting the water tank 1 and the heating module 9 are provided to preheat the water in the water tank 1. When the required water temperature exceeds the preset value of the water temperature in the water tank 1, the stored water in the water tank 1 can be heated by the heating module 9 and discharged from the fifth channel 8, thereby meeting the user's needs for different water temperatures. In addition, by preheating the water in the water tank 1, the speed of water temperature heating is accelerated, which better meets the various practical needs of users.

[0028] The first channel 4 includes a first pipe 10, a second pipe 11, a third pipe 12 and a fourth pipe 13 connected to the upper end of the water tank 1 along the height direction H. The first pipe 10 and the fourth pipe 13 are vertically arranged on the water tank 1. One end of the first pipe 10 is connected to the water inlet pipe 2, and one end of the fourth pipe 13 is connected to the inside of the water tank 1. The second pipe 11 and the third pipe 12 are horizontally arranged and parallel to each other. One end of the second pipe 11 is connected to the first pipe 10, and the other end is connected to one end of the third pipe 12 through a first solenoid valve 14. The other end of the fourth pipe 13 is connected to the third pipe 12. The first solenoid valve 14 is used to control the opening and closing of the first channel 4.

[0029] When the water tank 1 is filled with water, the first solenoid valve 14 opens the first channel 4 by connecting the second pipe 11 and the third pipe 12, and the water inlet pipe 2 injects water into the water tank 1 through the first channel 4. When the water level in the water tank 1 reaches a preset volume, the first solenoid valve 14 cuts off the connection between the second pipe 11 and the third pipe 12, closing the first channel 4. Preferably, the first pipe 10, the second pipe 11, the third pipe 12 and the fourth pipe 13 are integrally injection molded.

[0030] The second channel 5 has a fifth pipe 15 and a sixth pipe 16 connected to the upper end of the water tank 1 along the height direction H. The fifth pipe 15 and the sixth pipe 16 are arranged horizontally and parallel to each other. One end of the fifth pipe 15 is connected to the first pipe 10 and is located above the second pipe 11, and the other end is connected to one end of the sixth pipe 16 through a second solenoid valve 17. The other end of the sixth pipe 16 is connected to the water outlet 3. The second solenoid valve 17 is used to control the opening and closing of the second channel 5.

[0031] When the water tank 1 is filled with water or the first electromagnetic valve 14 closes the first channel 4, when it is necessary to discharge the normal temperature water, the second electromagnetic valve 17 opens the second channel 5 by connecting the fifth pipe 15 and the sixth pipe 16. In this way, part or all of the normal temperature water flowing into the water inlet pipe 2 will flow through the fifth pipe 15 and the sixth pipe 16, and then flow out from the water outlet 3. Preferably, the first pipe 10, the second pipe 11, the third pipe 12, the fourth pipe 13, the fifth pipe 15 and the sixth pipe 16 are integrally injection molded.

[0032] The heating module 9 includes an electrically connected circuit board 18, a water pump 19, a heater and a temperature sensor. A seventh pipe forming a third channel 6 is arranged between the inlet end of the water pump 19 and the water tank 1. The seventh pipe is arranged horizontally. The outlet end of the water pump 19 is connected to a heating pipe 20. The heater is arranged on one side of the heating pipe 20 for heating the water in the heating pipe 20. The temperature sensor is connected in the water tank 1 for detecting the water temperature in the water tank 1.

[0033] The fourth channel 7 has an eighth pipe 21, a ninth pipe 22 and a tenth pipe 23. One end of the eighth pipe 21 is connected to the heating pipe 20, and the other end is provided with a reversing valve 24. The ninth pipe 22 is horizontally arranged and one end is connected to the reversing valve 24, and the other end is connected to the tenth pipe 23. The tenth pipe 23 is vertically arranged and one end is connected to the water tank 1, and the other end is connected to the other end of the ninth pipe 22, which is used to introduce the water heated by the heating module 9 into the water tank 1, so as to realize preheating of the water stored in the water tank 1.

[0034] The fifth channel 8 includes an eleventh pipe 25 , one end of which is connected to the reversing valve 24 , and the other end of which is connected to the water outlet 3 , so as to store water in the water tank 1 or to heat the water in the water tank 1 so that it can be discharged from the water outlet 3 .

[0035] The present solution further comprises an exhaust passage 26 , one end of which is connected to the water tank 1 , and the other end of which is connected to the water outlet 3 , for exhausting the steam in the water tank 1 .

[0036] Since the water tank 1 is in a sealed state, the water in the water tank 1 will generate a small amount of steam after being preheated. Such steam in the sealed water tank 1 will affect the normal operation of the water tank 1. The exhaust channel 26 in this solution is used to discharge such steam into the water outlet 3, and when the water outlet 3 is opened, or when the water outlet 3 discharges water at normal temperature, the steam will condense under the action of heat exchange, thereby ensuring the normal operation of the water tank 1.

[0037] Preferably, a transition channel is provided in the water outlet 3 , and the transition channel is used to connect the ninth pipeline 22 and the reversing valve 24 .

[0038] Preferably, the water inlet pipe 2 includes a water pipe joint 28 arranged on one side of the water tank 1 and a hose 27 connected to the water pipe joint 28 at one end. The hose 27 extends along the outer wall of the water tank 1 and is connected to the first pipe 10 at the other end.
