Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 9 As shown, this embodiment discloses a wall-mounted boiler water channel module, including a water inlet valve 1, a water outlet valve 2 and an open component;

[0034] like Figures 1 to 3 As shown, the water inlet valve 1 includes a cold water inlet 11, a first installation cavity 12, a cold water plate exchange inlet 13 and a hot water plate exchange outlet 14.

The specific water circuit flow direction is: boiler-hot water inlet 26-three-way valve 3-floor heating inlet 22-floor heating pipeline-floor heating return pipe 51-third installation cavity 41-water pump interface 44-water pump-boiler; after being heated by the boiler, the water enters the water inlet valve 1 from the hot water inlet 26, and the hot water is cooled by the floor heating pipeline and then transported to the boiler again by the water pump for heating, thereby realizing the circulating heating of the floor heating water circuit.

[0040] The hot water inlet 26, the three-way valve 3, the hot water plate exchange inlet 23, the hot water plate exchange outlet 14, the third installation cavity 41 and the water pump interface 44 form a third water circuit. The third water circuit is a boiler circulation water circuit for heating bathroom water. The specific water flow direction is: boiler-hot water inlet 26-three-way valve 3-hot water plate exchange inlet 23-plate exchanger 100-hot water plate exchanger outlet 14-third installation cavity 41-water pump interface 44-water pump-boiler; after the hot water is cooled by heat exchange in the plate exchanger 100, it is transported to the boiler again by the water pump for heating, thereby realizing the circulating heating of bathroom water.

[0041] In the present embodiment, both the floor heating water circuit and the boiler circulating water circuit need to pass through the third installation cavity 41, and the third installation cavity 41 is connected with the open water tank 200 through the water tank interface 42 at the upper end, thereby realizing the open design of the floor heating water circuit and the boiler circulating water circuit, so that there is no pipeline pressure in these two pipelines, which can effectively improve the service life of components related to these two water circuits and reduce the probability of water leakage; and water is stored in the open water tank 200, and through the open water tank 200, the floor heating water circuit and the boiler circulating water circuit can be automatically replenished without manual or electric control.

[0042] like Figures 4 to 7 As shown, the third installation cavity 41 is vertically arranged, and a fourth channel 43 is provided at the lower part of the third installation cavity 41, and the fourth channel 43 is respectively connected with the hot water plate exchange outlet 14 and the floor heating return water outlet 51, and a water vapor separation core 7 is provided in the third installation cavity 41, and the third installation cavity 41 is divided by the water vapor separation core 7 to form a first cavity 411, a second cavity 412, a liquid passing area 413 and a third cavity 414 that are connected, and the first cavity 411 is directly connected with the fourth channel 43, and the third cavity 414 is directly connected with the water pump interface 44. Specifically, the water vapor separation core 7 includes an arc rib 71, and the first cavity 411 is located in the area surrounded by the arc rib 71. In the domain, a platform 72 is provided on the upper part of the arc rib 71, a baffle 73 is provided on the upper part of the platform 72, an annular platform 75 is provided on the upper part of the baffle 73, and baffle ribs 74 are provided on both sides of the baffle 73. The second cavity 412 is located between the two baffle ribs 74, the upper part of one baffle rib 74 is connected to the annular platform 75 and the upper part of the other baffle rib 74 is provided with a notch 76, the baffle rib 74 connected to the annular platform 75 is provided with an arc surface 78, the liquid passing area 413 is located in the notch 76, the third cavity 414 is located on the side of the baffle 73 away from the baffle rib 74, and a through hole 77 is provided in the annular platform 75, and the through hole 77 is respectively connected to the water tank interface 42 and the third cavity 414.

[0043] During the operation of the floor heating water circuit and the boiler circulating water circuit, the hot water inside will contain bubbles, so it is necessary to separate water and gas. When the hot water enters the third installation cavity 41 vertically from the fourth channel 43, the hot water passes through the water-gas separation core 7 so that the flow direction of the hot water in the third installation cavity 41 is: first cavity 411-second cavity 412-liquid passage area 413-third cavity 414.

[0044] The cross-sectional size of the third installation cavity 41 is larger than that of the fourth channel 43. The position of the liquid passing area 413 is higher than the water pump interface 44. When the hot water fourth channel 43 directly rushes into the first cavity 411, it is blocked by the platform 72, reducing the flow rate of the hot water and making the hot water diffuse into the flat second cavity 412, and then passing through the gap 76 (liquid passing area 413) into the third cavity 414. Since the position of the liquid passing area 413 is higher than the water pump interface 44, the hot water has a downward trend in the third installation cavity 41. The stroke is as follows: Figure 7 The flow direction is shown in b; the vapor in the hot water tends to rise, forming a Figure 7 As shown in the flow direction a, hot water is finally discharged from the water pump interface 44, and the vapor passes through the through hole 77 and is discharged into the open water tank 200 from the water tank interface 42 to achieve water-gas separation. By separating water and gas from the hot water in the third installation cavity 41, the gas content in the floor heating water circuit and the boiler circulating water circuit can be effectively reduced, thereby improving the hot water circulation effect.

[0045] The annular platform 75 is located in the third installation cavity 41, and a first limiting rib 415 is provided at the bottom of the third installation cavity 41. The water-gas separation core 7 is inserted into the area surrounded by the first limiting rib 415. Two second limiting ribs 416 are provided on the inner wall of the third installation cavity 41. The two retaining ribs 74 respectively abut against the opposite sides of the two second limiting ribs 416. By setting the first limiting rib 415 and the second limiting rib 416, the water-gas separation core 7 can be fixed.

[0046] like Figures 1 to 4 As shown, the open shell 4 includes a fourth interface 46, a third interface 45 is provided on the side of the fourth interface 46, and the water inlet valve 1 includes a first interface 15, one end of the first interface 15 is connected to the hot water plate exchange outlet 14 and the other end is connected to the third interface 45, the first interface 15 and the third interface 45 are fixed by plug-in, and the connection is convenient.

[0047] like Figure 4As shown, the valve body 5 includes a fifth interface 52, a fifth channel 53, a sixth interface 54 and a sixth channel 55, one end of the fourth interface 46 is connected to the lower part of the fourth channel 43 and the other end is connected to the fifth interface 52, the other end of the fifth interface 52 is connected to the fifth channel 53, one end of the sixth channel 55 is connected to the floor heating return water port 51 and the other end is connected to the fifth channel 53, a drain valve 6 is installed in the sixth interface 54, the drain valve 6 includes a connecting member 61 and a valve stem 63 threadedly connected to the connecting member 61, the connecting member 61 is sealingly installed in the sixth interface 54, a filter screen 62 is provided on the upper part of the connecting member 61, the upper part of the filter screen 62 abuts against the lower end of the fifth channel 53, the fifth channel 53 is connected to the sixth channel 55 through the filter screen 62, and the upper end of the valve stem 63 can be inserted into the filter screen 62 or detached from the connecting member 61.

[0048] The floor heating water circuit and the boiler circulating water circuit are both connected to the drain valve 6. Due to the influence of water quality, scale will be generated inside the hot water due to long-term heating and circulation. By setting the drain valve 6, the hot water in the floor heating water circuit and the boiler circulating water circuit and the water in the open water tank 200 can be discharged, reducing the risk of pipeline blockage. The floor heating water circuit and the boiler circulating water circuit are separated by the filter 62, which effectively reduces the impact of impurities in the floor heating water circuit on the boiler circulating water circuit.

[0049] like Figure 8 and Fig. 9 As shown, the side of the water inlet valve 1 is provided with a second interface 16, and a water replenishment valve 8 is installed at the end of the second interface 16. The water replenishment valve 8 is a solenoid valve, including a first communication port 81 and a second communication port 82.

The second interface 16 is provided with a first channel 17 and a second channel 18 inside. The first channel 17 is connected to the first communication port 81, and the second channel 18 is connected to the second communication port 82.

The channel 17 is connected with the cold water plate exchange inlet 13, and the second channel 18 is connected with the hot water plate exchange outlet 14 through the third channel 19. When the water level in the open water tank 200 is too low or the hot water in the floor heating water circuit and the boiler circulating water circuit and the water in the open water tank 200 are discharged through the drain valve 6, a one-way valve is arranged in the first channel 17. Through the water replenishment valve 8 and the one-way valve, the cold water plate exchange inlet 13 and the hot water plate exchange outlet 14 can be connected in one direction, so that the floor heating water circuit, the boiler circulating water circuit and the open water tank 200 can be replenished with water, which is convenient to operate.
