Description

[0002] The energy-saving heating and hot water module stove with high heat net value is a high-efficiency, energy-saving and environment-friendly heating equipment.

If the fan runs abnormally, the negative pressure in the combustion chamber or the flue is too large, and the cold air from the outside may be sucked in, mixed with the high-temperature flue gas, and produce additional condensate water. At the same time, the negative pressure may interfere with the normal flow direction of the condensate water, and part of the accumulated water may be "sucked back" into the equipment. Therefore, the condensing module stove needs to be improved. SUMMARY

[0039] A liquid level detection module 7 is arranged at the upper end inside the shell mechanism 2 and used to detect the liquid level of the condensed water inside the shell mechanism 2.

[0040] With the above scheme, when the condensing module stove is in normal operation, the condensed water generated is discharged through the shell mechanism 2, and the movable mechanism 3, the first sealing mechanism 4, the second sealing mechanism 5 and the active adsorption mechanism 6 arranged inside the shell mechanism 2 will not hinder the discharge of the condensed water. The bottom of the shell mechanism 2 is connected to a drainage pipeline to guide the condensed water out of the module stove.

[0041] As shown in Figure 2 , Figure 3 and Figure 4 , the shell mechanism 2 includes an outer shell 21, an upper shell assembly 22 and a drainage shell 23. The upper shell assembly 22 and the drainage shell 23 are installed at the upper and lower ends of the outer shell 21. The upper shell assembly 22 includes a connecting shell 221 and a limiting shell 222. The limiting shell 222 is arranged at both ends of the connecting shell 221 and fixed inside the outer shell 21.

The bottom of the limiting shell 222 is provided with a water permeable hole, and the sealing element 37 can block the water permeable hole at the bottom of the limiting shell 222.

[0042] With the above scheme: when the module furnace is in normal operation, the lower sealing disc 34 and the upper sealing disc 35 are located at the two ends of the opening at the bottom of the limiting shell 222, and neither of them is in contact with the limiting shell 222, so as to facilitate the passage of condensed water, and when the fan is abnormally operated, causing excessive negative pressure in the combustion chamber or flue, under the adsorption of the negative pressure, the lower sealing disc 34 is in pressure contact with the bottom of the connecting shell 221, the bottom of the limiting shell 222 is blocked, and the first sealing mechanism 4, the second sealing mechanism 5, the movable shaft 33, the connecting frame 36 and the sealing piece 37 are all driven upward by the lower sealing disc 34, at this time the condensed water enters the inside of the outer shell 21 through the water-permeable hole at the bottom of the limiting shell 222; the first positioning frame 32 and the second positioning frame 39 are used to limit the movable shaft 33, so as to ensure the vertical movement of the movable shaft 33; when the movable shaft 33 moves downward, the sealing piece 37 will not move after being in pressure contact with the limiting shell 222, and at this time the elastic piece 38 is deformed, and the elastic piece 38 can reset the movable shaft 33 and the lower sealing disc 34 through the elastic restoring force.

[0044] Adopt the above scheme: when the fan runs abnormally and causes the negative pressure in the combustion chamber or flue to be too large, the lower sealing disc 34 is adsorbed by the negative pressure to block the bottom of the connecting shell 221, at this time, the first sealing disc 41 is in pressure contact with the first blocking ring 43 to block the lower end of the outer shell 21, so that the air passage in the outer shell 21 is blocked, and the condensed water cannot flow back; in this state, the condensed water enters the inside of the outer shell 21 through the water-permeable hole in the bottom of the limiting shell 222 and collects above the first sealing disc 41 and the first blocking ring 43; when the liquid level detection module 7 detects that the condensed water surface reaches a certain height, the first electromagnet 62 is energized to adsorb the first suction accessory 42, thereby driving the first sealing disc 41 to move downward; it is worth noting that when the first suction accessory 42 is in adsorption contact with the first electromagnet 62, the second sealing disc 51 is in pressure contact with the second blocking ring 53, and the upper sealing disc 35 is in pressure contact with the connecting shell 221; at this time, the air passage in the outer shell 21 is blocked by the cooperation of the second sealing disc 51 and the second blocking ring 53, and the condensed water originally above the first sealing disc 41 and the first blocking ring 43 falls to the second sealing disc 51 and the second blocking ring 53, and then the energization of the first electromagnet 62 is stopped, and the second electromagnet 63 is energized to adsorb the second suction accessory 52; at this time, the first sealing disc 41 is in pressure contact with the first blocking ring 43, and the condensed water originally above the second sealing disc 51 and the second blocking ring 53 is discharged through the drain shell 23.

[0045] Example two

[0046] When the fan runs abnormally and causes the negative pressure in the combustion chamber or flue to be too small, the second suction accessory 52 is kept in adsorption with the second electromagnet 63, the condensed water falls on the top of the first sealing disc 41 and the first blocking ring 43 through the water-permeable hole of the limiting shell 222, and the liquid level of the condensed water is detected by the liquid level detection module 7; when it is detected that the condensed water surface reaches a certain height, the energization of the second electromagnet 63 is stopped, and the first electromagnet 62 is energized to adsorb the first suction accessory 42; at this time, the second sealing disc 51 is in pressure contact with the second blocking ring 53, and the condensed water originally above the first sealing disc 41 and the first blocking ring 43 falls above the second sealing disc 51 and the second blocking ring 53; then the second electromagnet 63 is energized to adsorb the second suction accessory 52; at this time, the condensed water flows into the drain shell 23 through the gap between the second sealing disc 51 and the second blocking ring 53 and is discharged, and then the liquid level detection module 7 starts to detect again; in this way, the flue gas generated by combustion can be prevented from being discharged through the shell mechanism 2, and the safety during use is ensured.
