AI Technical Summary
[0003]但是燃气热水器使用时,现有热水器当用户关闭热水器后,燃烧室内残留的燃气仍会持续加热残留在加热水箱中的水体,过度加热的水体易产生局部汽化,形成高压蒸汽冲击管路,导致密封件老化或爆裂风险,引发安全隐患,同时,重启设备时需重新加热常温供水,预热过程不仅延长等待时间约30秒以上,更额外增加燃气消耗量,并且用户初期排放的管道存水直接被排入下水道,废水热能无法复用,既浪费水资源又损失可利用热能
[0012] Compared with the prior art, this utility model has the following beneficial effects: After the water heater is turned off, the water heated by the residual gas in the combustion chamber automatically flows into the storage tank through the drain pipe, the angled conveying pipe and the recovery pipe, avoiding energy waste. When restarting, the water in the storage tank re-enters the heating system through the circulation pipe and the inlet pipe, shortening the preheating time by about 100 minutes and reducing gas consumption. At the same time, the storage tank absorbs the overheated water in time, preventing the heating water tank from generating high-pressure steam or local overheating due to residual heat. The hot water collected in the storage tank can be directly used through the pipe, reducing hot water discharge waste.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of water heaters, and particularly to gas water heaters. Background Technology
[0002] Gas water heaters are household gas appliances that use gas as fuel to heat water through combustion and provide rapid water supply. They belong to the category of household appliances and are widely used in various home settings.
[0003] However, when using gas water heaters, even after the user turns off the water heater, the residual gas in the combustion chamber continues to heat the water remaining in the heating tank. Overheated water is prone to localized vaporization, forming high-pressure steam that impacts the pipes, leading to aging or bursting of seals and posing a safety hazard. At the same time, restarting the equipment requires reheating the room temperature water supply, which not only extends the waiting time by more than 30 seconds but also increases gas consumption. Furthermore, the water initially discharged by the user is directly discharged into the sewer, and the wastewater heat energy cannot be reused, wasting water resources and losing usable heat energy. Utility Model Content
[0004] The main purpose of this utility model is to provide a gas water heater that can effectively solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A gas water heater includes a mounting plate, a housing plate, and screw plates. The housing plate is fixedly mounted on the outside of the mounting plate. Two screw plates are fixedly mounted on the upper and lower ends of the mounting plate, respectively. A water inlet connector and a drain connector are fixedly mounted on the lower end of the mounting plate, with the water inlet connector located to one side of the drain connector. A gas connector is fixedly mounted on the lower end of the mounting plate, between the water inlet connector and the drain connector. A combustion chamber and a heating water tank are fixedly mounted on the inner side of the mounting plate, with the heating water tank fixedly mounted on the upper end of the combustion chamber.

When restarting, the water in the storage tank re-enters the heating system through the circulation pipe and the inlet pipe, shortening the preheating time by about 100 minutes and reducing gas consumption. At the same time, the storage tank absorbs the overheated water in time, preventing the heating water tank from generating high-pressure steam or local overheating due to residual heat. The hot water collected in the storage tank can be directly used through the pipe, reducing hot water discharge waste. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] like Figures 1-4 As shown, this refers to gas water heaters; please refer to this document for more details. Figures 1-4 The system includes a mounting plate 1, an outer shell plate 2, and screw plates 4. The outer shell plate 2 is fixedly installed on the outside of the mounting plate 1. Two screw plates 4 are fixedly installed on the upper and lower ends of the mounting plate 1, respectively. A water supply connector 7 and a drain connector 8 are fixedly installed on the lower end of the mounting plate 1, with the water supply connector 7 located on one side of the drain connector 8. A gas connector 9 is fixedly installed on the lower end of the mounting plate 1, located between the water supply connector 7 and the drain connector 8. A combustion chamber 10 and a heating water tank 11 are fixedly installed on the inner side of the mounting plate 1, with the heating water tank 11 fixedly installed on the upper end of the combustion chamber 10. A water inlet pipe 14 is fixedly installed on the upper end of the water supply connector 7, and a drain pipe 15 is fixedly installed on the upper end of the drain connector 8. A water storage tank 13 is located below the mounting plate 1. A circulation pipe 16 is fixedly installed on one side of the water storage tank 13, and a recovery pipe 17 is fixedly installed on the other side of the water storage tank 13. An angled conveying pipe 18 is fixedly installed on the upper end of the recovery pipe 17.
[0020] Please refer to this carefully. Figure 1 and Figure 3 A control panel 3 is fixedly installed on the front end of the outer shell 2. A control board 6 is fixedly installed on the inner side of the mounting plate 1, located on one side of the heating water tank 11. The control board 6 and the control panel 3 are connected by a wire.
[0021] Specifically, control panel 3 is the operation part, and the water heater is turned on and off through the circuit control of control board 6.
[0022] Please refer to this carefully. Figure 3 and Figure 4 A fan 12 is fixedly installed on the upper end of the heating water tank 11, and an exhaust connector 5 is fixedly installed on the upper end of the mounting plate 1 in front of the screw plate 4. The exhaust port of the fan 12 is connected to the exhaust connector 5.
[0023] Please refer to this carefully. Figure 3 and Figure 4 The inlet pipe 14 and the outlet pipe 15 are both located inside the mounting plate 1, and are fixedly connected to the inlet and outlet of the heating water tank 11, respectively.
[0024] Specifically, water is supplied to the heating water tank 11 through the water inlet pipe 14 via the water supply connector 7, and gas is supplied to the combustion chamber 10 via the gas connector 9 for combustion. The combustion chamber 10 then heats the water in the heating water tank 11, and the water is discharged through the drain pipe 15 and the drain connector 8. The fan 12 is used to discharge the flue gas generated by combustion to the outside.
[0025] Please refer to this carefully. Figures 1-4 Both the circulation pipe 16 and the recovery pipe 17 are inserted into the inner side of the mounting plate 1. The upper end of the circulation pipe 16 is fixedly connected to the water inlet pipe 14, and the end of the angled conveying pipe 18 away from the recovery pipe 17 is fixedly connected to the drain pipe 15.
[0026] Specifically, when hot water output from the water heater stops, the residual gas in the combustion chamber 10 will continue to burn for a period of time to heat the water. When the drain connector 8 is closed, the continuously heated water will flow through the drain pipe 15 from the angled delivery pipe 18 into the recovery pipe 17, and then flow to the water storage tank 13 to store and collect the water heated by the residual gas, preventing the residual gas from overheating the water. When the drain pipe 15 and drain connector 8 are draining normally, the inclination of the angled delivery pipe 18 will not affect its normal drainage. When the water heater is turned on again, the water in the water storage tank 13 can enter the inlet pipe 14 through the circulation pipe 16 for reuse.
[0027] Please refer to this carefully. Figures 1-4 A utilization pipe 19 is fixedly installed on one side of the water storage tank 13 below the circulation pipe 16. Valves are installed on the outside of both the circulation pipe 16 and the utilization pipe 19.
[0028] Specifically, by opening pipe 19, the hot water stored in water tank 13 can be released and used.
