Description

Technical Field

[0001] The utility model belongs to the field of natural gas heating, in particular to an antifreeze protection device for a natural gas heating furnace. Background Art

[0002] The full name of "wall-mounted boiler" is "gas wall-mounted heating boiler". It and gas instant water heaters are both fast heating devices without hot water storage devices, but there are essential differences in the functions. Gas wall-mounted boilers have powerful home central heating functions and can meet the heating needs of multiple rooms. They can also take into account hot water bathing functions. However, when the wall-mounted boiler is in use, it needs to be protected from freezing. The existing anti-freeze protection measures usually leave the heated water in the water tank inside the wall-mounted boiler and use hot water to protect the wall-mounted boiler from freezing. However, when the wall-mounted boiler is not used for a long time, the water is easy to freeze in the water tank at low temperatures. After freezing, the volume of the ice becomes larger, which can easily damage the water tank. However, if the water in the water tank is directly discharged, it is easy to waste water resources. Therefore, we have designed a natural gas heating furnace antifreeze protection device that can collect water. Utility Model Content

[0015] A natural gas heating furnace antifreeze protection device, such as Figure 1As shown, it includes a wall-mounted boiler 1, which is characterized in that: a round box 2 with an opening on one side is fixedly installed on one side of the wall-mounted boiler 1, the round box 2 is open on one side away from the wall-mounted boiler 1, a folding tube 3 is fixedly installed in the round box 2, one end of the folding tube 3 is fixedly installed with a baffle 4, one end of the folding tube 3 is fixedly connected to one side of the baffle 4, the other end of the folding tube 3 is fixedly connected to the inner wall of the round box 2, the baffle 4 fits well with the round box 2, and a spring telescopic rod 5 is fixedly installed on the baffle 4 respectively, the movable end of the spring telescopic rod 5 is fixedly connected to one side of the baffle 4, the spring telescopic rod 5 is fixedly installed on the round box 2, and the fixed end of the spring telescopic rod 5 is fixedly installed on the round box 2. When the spring telescopic rod 5 is in a state of neither stretching nor compressing, the baffle 4 can It can keep fitting with the round box 2, the round box 2 is closed, the baffle 4 is connected to the water outlet pipe 6, the water outlet pipe 6 is connected with the folding pipe 3, the baffle 4 is provided with a reserved hole, the water outlet pipe 6 is connected with the inside of the folding pipe 3 through the reserved hole, the water outlet pipe 6 is fixedly installed on the baffle 4, the water outlet pipe 6 is fixedly provided with a first valve 7, the baffle 4 is fixedly provided with a water inlet pipe 8 connected with the folding pipe 3, the water inlet pipe 8 is a hose, the water inlet pipe 8 is long enough and will not hinder the movement of the folding pipe 3 during the elongation of the folding pipe 3. One end of the water inlet pipe 8 is connected with the wall-mounted boiler 1, and both ends of the water inlet pipe 8 are fixedly installed on the baffle 4 and the wall-mounted boiler 1 in turn. The water inlet pipe 8 is connected to install a water pump 9, and the water pump 9 is fixedly installed on the wall-mounted boiler 1. The utility model has a simple structure and an ingenious design. When the wall-mounted boiler 1 is not in use, water is pumped into the folding tube 3 to collect the water, thereby preventing waste of water resources. Even if the water freezes in the folding tube 3 and the volume increases, it will not cause damage to the folding tube 3. At the same time, when not in use, the folding tube 3 is in a folded state, which can reduce the volume and save space, meet actual needs, and is suitable for promotion. When using the utility model, when the wall-mounted boiler 1 is not in use, the water pump 9 is started, and the water pump 9 sends the water retained in the wall-mounted boiler 1 into the foldable tube 3 through the water inlet pipe 8. As the water volume increases, under the action of water, the baffle 4 drives the spring telescopic rod 5 to extend, the baffle 4 moves to the left, and the foldable tube 3 extends. Even if the water freezes in the foldable tube 3 under low temperature, the volume of the water increases after it freezes. At this time, the foldable tube 3 can drive the baffle 4 to continue to move to the left and extend under the push of the ice, and the spring telescopic rod 5 is stretched, which can prevent the water from increasing in volume after freezing and causing damage to the foldable tube 3. When the foldable tube 3 is not in use, under the action of the spring telescopic rod 5, the foldable tube 3 is folded up, which can reduce the floor space of the foldable tube 3.

[0016] Specifically, as shown in the figure, the wall-mounted boiler 1 of this embodiment includes a wall-mounted boiler body 27. The bottom of the wall-mounted boiler body 27 is connected to the domestic hot water outlet pipe 20, the heating outlet pipe 21, the gas inlet pipe 22, the tap water inlet pipe 23, and the heating return pipe 24. The domestic hot water outlet pipe 20, the heating outlet pipe 21, the gas inlet pipe 22, the tap water inlet pipe 23, and the heating return pipe 24 are all connected and installed with a second valve 25. The water inlet pipe 8 is connected to the domestic hot water outlet pipe 20 via a third three-way pipe 26. When the corresponding function is needed, the corresponding second valve 25 is opened.

[0017] Specifically, as shown in the figure, the two sides of the water pump 9 described in this embodiment are connected to the first tee 30 and the second tee 31 in sequence, and the upper and lower ends of the first tee 30 and the second tee 31 are connected to the first transverse pipe 32 and the second transverse pipe 33 respectively.

The first transverse pipe 32 is connected to the water inlet pipe 8, and the second transverse pipe 33 is connected to the third tee 26. When the wall-mounted boiler 1 is not in use and the remaining water needs to be pumped out from the wall-mounted boiler body 27, the fourth valve 35 at the lower end of the second three-way pipe 31 and the third valve 34 at the upper end of the first three-way pipe 30 are opened, and the water pump 9 is started. At this time, water enters the water pump 9 through the domestic hot water outlet pipe 20, the third three-way pipe 26, and the lower end of the second three-way pipe 31, and then enters the folding pipe 3 through the upper end of the first three-way pipe 30 and the water inlet pipe 8; when the wall-mounted boiler 1 needs to be used again, the fourth valve 35 at the upper end of the second three-way pipe 31 and the third valve 34 at the lower end of the first three-way pipe 30 are opened, and the water pump 9 is started. The water pump 9 draws the water in the folding pipe 3 through the water inlet pipe 8 and the upper end of the second three-way pipe 31 into the water pump 8, and then passes through the lower end of the first three-way pipe 30, the third three-way pipe 26, and the domestic hot water outlet pipe 20 to re-enter the wall-mounted boiler body 27.

[0018] Furthermore, as shown in the figure, a heating wire 40 is fixedly installed inside the round box 2 of this embodiment. When the water in the foldable tube 3 freezes, the heating wire 40 is activated to heat the ice in the foldable tube 3, turning it into water, which is convenient for re-pumping the water into the wall-mounted boiler 1.

[0019] Furthermore, as shown in the figure, a heat-insulating layer 50 is fixedly provided on the inner wall of the round box 2 in this embodiment. The heat-insulating layer 50 is fixedly mounted on the inner wall of the round box 2, and the heating wire 40 is fixedly mounted on the heat-insulating layer 50. The heat-insulating layer 50 can insulate the round box 2 and prevent the heat inside the round box 2 from being dissipated too quickly to the outside.
