TECHNICAL FIELD

[0001] The utility model relates to gas wall -hanging stove chimney anti -icing technical field especially relates to a gas wall -hanging stove chimney anti -icing device. BACKGROUND

[0002] At present, in the operation of gas wall -hanging stove, through the coaxial chimney that protrudes the wall realizes the function of inhaling fresh air outside and discharging internal exhaust gas, but in low temperature environment especially in winter, the chimney outlet position is contacted to cold air, and the high-temperature gas discharged contains a large amount of water vapor, which is prone to cause the phenomenon of ice or frost formation at the chimney outlet part, and if no precautions are taken, it may seriously affect the working efficiency of the wall -hanging stove or even cause safety problems, for example, the condensate water freezes and blocks the air inlet or exhaust port, at this time, the stove will work poorly, and there will be incomplete combustion, and C0 poisoning phenomenon occurs.

[0003] The common method is to increase the heat preservation measures such as adding insulation layer to prevent freezing, mainly through the way of adding insulation material to the outer layer of the chimney to slow down the heat loss speed, but this method has certain limitations: pure reliance on insulation cannot completely eliminate the risk of icing, especially in extreme weather conditions.

[0004] The traditional anti -icing means either has limited effect or high cost, especially for those families in severe cold regions, how to solve this problem efficiently and energy -saving has become one of the key technical bottlenecks to be conquered. UTILITY MODEL CONTENTS

[0005] In view of the above problems existing in the prior art, the main purpose of the utility model is to provide a gas wall -hanging stove chimney anti -icing device.

[0016] In a preferred embodiment, the heating element is made of quartz glass fiber wrapped with metal foil, and both the heating element and the icing sensor are electrically connected to the controller.

[0017] By adopting the above technical solution, and using quartz glass fiber wrapped with metal foil, it has high thermal conductivity and can withstand frequent temperature changes without damage, thereby improving the service life of the heating element.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1.

[0026] Reference Figures 1-3 An anti-icing device for a gas-fired wall-hung boiler chimney includes a boiler body 1, a chimney outer cylinder 4 at the top of the boiler body 1, an inner chimney cylinder 5 fixedly installed inside the outer chimney cylinder 4, a mounting bracket 7 on the outer wall of the outer chimney cylinder 4, and heating tubes 9 fixedly installed at equal intervals on one side of the mounting bracket 7, with multiple heating tubes 9 forming a cage-like structure. An icing sensor 14 is fixedly installed on the outer side of the outer chimney cylinder 4, and a controller 2 is fixedly installed on the top of the boiler body 1. The icing sensor 14 is precisely installed at the end of the chimney where it is most susceptible to low temperatures, for real-time monitoring of any signs of icing. The heating tubes 9, as the core heating unit, ensure rapid local heating without interfering with normal ventilation. When the ambient temperature drops sharply, causing icing to appear on the surface of the chimney... When a slight frost appears, the highly sensitive icing sensor 14 immediately detects the change and sends an alarm signal to the controller 2. Upon receiving the command, the controller 2 quickly activates the preset program command to turn on the associated circuit, which powers the heating element 9 to generate heat. The chimney inlet 6 is located near the heating element 9. The heating element 9 can heat the chimney exhaust port 12 inside the chimney inner cylinder 5 and the chimney inlet 6 outside the chimney outer cylinder 4. In this way, it directly acts on the surrounding metal shell to heat up and melt the thin ice and snow particles attached to it. This cycle continues until the external weather conditions improve and no longer pose a further threat. Compared with traditional static protection measures, the dynamic heating mode ensures immediate response and takes into account the concept of energy conservation.

[0027] Reference Figure 3 Chimney air inlets 6 are equidistantly provided on the outer side of the outer chimney cylinder 4. The chimney air inlets 6 are located at the heating tubes 9. A chimney exhaust port 12 is provided at the end of the inner chimney cylinder 5 away from the furnace body 1. An icing sensor 14 is located on the side near the chimney exhaust port 12. A fixing ring 8 is provided on the outer side of the inner chimney cylinder 5. The heating tubes 9 are all inserted into the fixing ring 8. The chimney air inlets 6 and the chimney exhaust port 12 facilitate the intake of fresh air from the outside and the exhaust of waste gas from the inside, so as to cooperate with the furnace body 1. The fixing ring 8 can further limit the multiple heating tubes 9 and play a fixing role, making the heating tubes 9 more stable during use.

[0028] Reference Figure 3Mounting rings 10 are fixedly connected at equal intervals on the side of the mounting bracket 7 away from the heating tube 9. Both ends of the mounting rings 10 are provided with fixing bolts 11. The mounting rings 10 are connected to the outer cylinder 4 of the chimney by fixing bolts 11. The use of mounting rings 10 and fixing bolts 11 makes it easy to install the heating tube 9 on the inner wall of the inner cylinder 5 of the chimney, which facilitates the replacement and installation of the heating tube 9. The compact and simple overall design not only facilitates on-site installation and debugging, but also makes later maintenance easier and more convenient.

[0029] Reference Figure 1 A wall 3 is provided on one side of the furnace body 1, and the outer casing 4 of the chimney is installed inside the wall 3, so that the outer casing 4 of the chimney can be installed.

[0030] Reference Figure 3 There are eight heating tubes 9. A bent pipe 13 is fixedly connected to the top of the furnace body 1. The end of the bent pipe 13 away from the furnace body 1 is fixedly connected to the outer casing 4 of the chimney. Through the function of the bent pipe 13, it can be used to connect the outer casing 4 of the chimney to the furnace body 1, which meets the requirements of the bending position.

[0031] Reference Figure 3 The heating element 9 is made of quartz glass fiber wrapped with metal foil. Both the heating element 9 and the icing sensor 14 are electrically connected to the controller 2. By using quartz glass fiber wrapped with metal foil, it has high thermal conductivity and can withstand frequent temperature changes without damage, thereby improving the service life of the heating element 9. The controller 2 can control the start and stop of the icing sensor 14 and the heating element 9.

[0032] Working principle: First, the power cord is directly connected to the indoor power socket to power the entire system. When the ambient temperature drops sharply and the surface of the chimney begins to show a slight frost, the highly sensitive icing sensor 14 immediately detects the change and sends an alarm signal to the controller 2. Upon receiving the instruction, the controller 2 quickly activates the preset program command to turn on the associated circuit, so that the heating tube 9 is energized and generates heat. In this way, it directly acts on the surrounding metal shell to heat up and melt the thin ice and snow particles attached to it. This cycle continues until the external weather conditions improve and no longer pose a further threat.

[0033] Furthermore, the bend 13 can be used to connect the outer casing 4 of the chimney to the furnace body 1, satisfying the use of the bending position. The setting of the fixing ring 8 can further limit the multiple heating tubes 9, playing a fixing role, making the heating tubes 9 more stable during use. The use of the installation ring block 10 and the fixing bolt 11 makes it easy to install the heating tubes 9 on the inner wall of the inner casing 5 of the chimney, thus facilitating the replacement and installation of the heating tubes 9.

[0034] By using quartz glass fiber wrapped with metal foil, it has high thermal conductivity and can withstand frequent temperature changes without damage, thus improving the service life of the heating element 9. In general, compared with traditional static protection measures, dynamic heating mode ensures immediate response and takes into account the concept of energy saving. The compact and simple overall design is not only easy to install and debug on site, but also easier and more convenient to maintain later.
