Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of gas water heaters, specifically an antifreeze protection device for gas water heaters. Background Technology
[0002] Gas water heaters are household appliances that use natural gas, liquefied petroleum gas, or other fuels to quickly heat cold water to a set temperature through combustion. They can meet the hot water needs of various scenarios such as daily washing, showering, and kitchen cleaning. Compared with electric water heaters, they have the advantages of fast heating, no need for long-term water storage, continuous hot water supply, and relatively low energy costs.
[0003] Water vapor generated during the operation of a water heater, condensation in the installation environment, or residual moisture after use can easily penetrate into the internal electronic components, leading to circuit oxidation, contact corrosion, or decreased sensor sensitivity. This can result in false triggering or malfunction, causing the device to fail to activate heating and antifreeze in time at low temperatures, or to continue operating even after the temperature rises. Furthermore, antifreeze requires manual opening of the waterproof valve to drain residual cold water, as the device cannot automatically drain the water. It also cannot simultaneously activate the heater to heat and remove water from the inside of the water heater, increasing the user's workload. The uncertainty of manual operation also affects the antifreeze effect, and the entire process cannot achieve fully automated control. Therefore, this application proposes an antifreeze protection device for gas water heaters. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] Depend on Figures 1-6 The present invention includes a wall 1 and an antifreeze mechanism. A water heater 2 is installed on one side of the wall 1. Multiple mounting columns 9 are fixedly installed on the wall 1. The multiple mounting columns 9 can ensure the stability of the water heater 2. The mounting columns 9 are fixedly connected to the water heater 2. A water inlet pipe 3 and a water outlet pipe 4 are fixedly installed on the water heater 2, and the water inlet pipe 3 and the water outlet pipe 4 are arranged opposite to each other. The antifreeze mechanism includes a water outlet pipe 5 fixedly installed on the water heater 2 and passing through the water heater 2. An installation frame 6 is fixedly installed on the water outlet pipe 5. A sealing element is installed on the installation frame 6. The sealing element includes a fixing plate 10 that passes through the installation frame 6 and is slidably connected to it. A rubber pad that abuts against the inner wall of the installation frame 6 is fixedly installed on the fixing plate 10 to ensure that water will not flow out of the installation frame 6 when the fixing plate 10 abuts against the installation frame 6. A fixing post 8 that is fixedly connected to one of the connecting plates 20 is fixedly installed on the fixing plate 10. A fixed frame 7 is fixedly installed on the water heater 2, which runs through the water heater 2. A heating element is fixedly installed at the upper end of the fixed frame 7. The heating element includes a heater 12 fixedly installed on one of the connecting plates 20. A wire 18 is fixedly installed on the heater 12, which runs through the connecting plate 20. A fixed cylinder 15 is sleeved on the wire 18 and fixedly connected to it. The fixed cylinder 15 is fixedly connected to the connecting plate 20. A plug 16 is fixedly installed on the wire 18 and fixedly connected to the fixed cylinder 15. A connecting frame 14 located inside the water heater 2 is fixedly installed on the fixed frame 7. A socket 17 opposite to the plug 16 is fixedly installed inside the connecting frame 14. The fixed cylinder 15 runs through the connecting frame 14 and is slidably connected to it. The fixed frame 7 contains an expansion liquid located between two mounting plates 19. When the temperature inside the water heater 2 drops, the expansion liquid contracts due to the cold, causing the two mounting plates 19 to move. One mounting plate 19 moves the connecting plate 20, which in turn moves the fixing column 8. The fixing column 8 then moves the fixing plate 10. The movement of the fixing plate 10 allows water inside the water heater 2 to flow out through the outlet pipe 5. The other mounting plate 19 moves the connecting plate 20 it is fixedly connected to, which in turn moves the fixing cylinder 15. The fixing cylinder 15 moves the wire 18, which in turn moves the plug 16. The plug 16 moves and comes into contact with the socket 17 it is positioned opposite to, thus energizing the heater 12 and heating the water heater 2. This evaporates the water remaining inside the water heater 2. The mechanical structure provides antifreeze protection for the water heater 2, thus preventing instability in the antifreeze protection due to instability in the electronic structure. Two mounting plates 19 are slidably connected inside the fixed frame 7 and slide against the inner wall of the fixed frame 7. Two through holes 13 are fixedly installed on the fixed frame 7, which can ensure that the connecting plate 20 can move along the direction of the through hole 13. The two through holes 13 are arranged opposite to the two mounting plates 19. The connecting plate 20 slides against the inner wall of the through hole 13. The fixed frame 7 is provided with two sliding grooves 21, which are arranged opposite to the two mounting plates 19. A baffle 11 is slidably connected inside the sliding groove 21 and slides against the inner wall of the sliding groove 21. The baffle 11 can prevent the expanding liquid from flowing out of the fixed frame 7. The baffle 11 is fixedly connected to the connecting plate 20. The mounting plate 19 is fixedly installed with the connecting plate 20. One connecting plate 20 is fixedly connected to the heating element, and the other connecting plate 20 is fixedly connected to the sealing element.
[0017] Working principle: During operation, an expansion liquid is placed inside the fixed frame 7 between the two mounting plates 19. When the temperature inside the water heater 2 drops, the expansion liquid contracts due to the cold, causing the two mounting plates 19 to move. One mounting plate 19 moves the connecting plate 20, which in turn moves the fixing column 8. The fixing column 8 then moves the fixing plate 10. The movement of the fixing plate 10 allows water inside the water heater 2 to flow out through the outlet pipe 5. The other mounting plate 19 moves the connecting plate 20 it is fixedly connected to, which in turn moves the fixing cylinder 15. The fixing cylinder 15 moves the wire 18, which in turn moves the plug 16. The plug 16 moves and comes into contact with the socket 17 it is positioned opposite to, thus energizing the heater 12 and heating the water heater 2. This evaporates the residual water inside the water heater 2. The mechanical structure provides antifreeze protection for the water heater 2, thus preventing instability in the antifreeze protection caused by instability in the electronic structure.
