Abstract
Description
Technical Field
[0001] This utility model relates to the field of water heater technology, and in particular to a new type of gas water heater technology disclosure document. Background Technology
[0002] Gas water heaters currently on the market have many obvious defects, which severely limit their application in mobile scenarios:
[0003] Poor size and portability: Traditional household gas water heaters are bulky and heavy, making them unsuitable for installation in confined spaces such as trucks and RVs. When used outdoors, moving them requires multiple people, resulting in serious portability issues.
[0004] Gas cylinder replacement is cumbersome: Most existing equipment uses a closed cabinet or bolt-fixed panel design, which requires tools to disassemble the outer shell when replacing the gas cylinder, making it impossible to meet the need for quick gas cylinder replacement in outdoor emergency situations.
[0005] Low heating efficiency and temperature control accuracy: The straight tube heat exchange structure has a small contact area between the fire plate and the water pipe, and the heat exchange rate can only reach 70%-75%. Moreover, the water temperature fluctuates greatly and the temperature deviation is large.
[0006] Significant safety hazards: The gas cylinder and the heating chamber are not effectively isolated, and the hot gas will directly bake the cylinder, causing the surface temperature of the cylinder to be too high, which can easily lead to gas expansion and explosion.
[0007] Currently, existing technologies do not offer a solution that can simultaneously address the aforementioned issues, achieving compact size, convenient bottle replacement, efficient heating, and safe control, leaving a significant technological gap in mobile applications.

[0044] like Figure 1-5 The present invention provides a novel gas water heater, including a housing 1, and further comprising:
[0045] Replace component 2 for easier replacement of the gas cylinder;
[0046] Heating component 3 is used to heat water;
[0047] Intelligent control component 4 is used for intelligent control of the entire device;
[0048] in:
[0049] The replacement component 2 includes a gas compartment 5 located at the lower left corner of the housing 1, a door panel 6 hinged to the lower left front of the housing 1, and gas cylinders 7 symmetrically installed inside the gas compartment 5.
[0050] The heating assembly 3 includes a heating chamber 8 located in the upper half of the housing 1 and directly above the gas chamber 5, a fire plate 9 connected to the gas cylinder 7 via a pipe, and a copper tube ring 10 located at the bottom of the heating chamber 8 and fitted onto the fire plate 9.
[0051] The intelligent control component 4 includes an electronic module 11 located on the other side inside the enclosure 1, a temperature adjustment knob 12 and a gas fire level switch 13 located on the front of the enclosure 1, and a temperature display 14 located on the outer surface of the enclosure 1.
[0052] The enclosure 1 is made of 6061-T6 aluminum alloy with anodized surface treatment, hardness ≥15HW, dimensions ≤35cm×25cm×20cm, and weight ≤5kg.
[0053] In this embodiment, specifically, the opening angle of the door panel 6 is greater than or equal to 180 degrees, and a sealing strip 15 is provided on the inner side of the door panel 6. A heat-insulating steel plate 16 is provided between the heating chamber 8 and the gas chamber 5.
[0054] In this embodiment, specifically, the fire plate 9 has a porous structure, and the copper tube ring 10 is spiral-shaped.
[0055] In this embodiment, specifically, the electronic module 11 of the intelligent control component 4 integrates an MCU control unit 17, a wireless communication module 18, and a relay group 19, and also includes a heat insulation cover 20 disposed in the heating chamber 8. The heat insulation cover 20 covers the fire plate 9 and the copper tube ring 10. An exhaust pipe 21 is connected to the heat insulation cover 20. The exhaust pipe 21 penetrates the top wall of the heating chamber 8, and a windproof cap 22 is provided on the top of the exhaust pipe 21. The heat insulation cover 20 is made of fireproof material. The combination of the heat insulation steel plate 16 and the heat insulation cover 20 prevents the gas cylinder 7 from overheating.
[0056] In this embodiment, specifically, it also includes an inlet pipe 23 and an outlet pipe 24. Both the inlet pipe 23 and the outlet pipe 24 are connected to the copper pipe ring 10 and pass through the housing 1. The outlet pipe 24 is located below the inlet pipe 23 and a temperature sensor 25 is connected in series on the outlet pipe 24. The temperature sensor 25 has an accuracy of ±0.5℃.
[0057] In this embodiment, specifically, the electronic control module 12, temperature adjustment knob 13, fire switch 14, temperature display 15, and temperature sensor 25 are electrically connected.
[0058] When this utility model is in operation:
[0059] I. Basic Architectural Principles of Box 1
[0060] The housing 1 is made of 6061-T6 aluminum alloy and is divided into a lower left gas compartment 5, an upper heating compartment 8, and a right-side electrical control compartment integrating an electronic module 11 by sheet metal parts, forming a three-zone isolation layout of "gas source-heating-control".
[0061] Gas compartment 5: Gas cylinder 7 is installed in the lower left independent space and is opened by hinged door panel 6. The inner sealing strip 15 forms a sealing pressure of 3kPa to prevent gas leakage.
[0062] Heating chamber 8: Located directly above gas chamber 5, it is isolated from high temperature by a 3mm thick heat-insulating steel plate 16 with a temperature difference ≥30℃. The inner wall ceramic fiber heat insulation cover 20 wraps the fire plate 9 and copper tube ring 10 to reduce heat loss.
[0063] Electrical control compartment: The right-side independent space protects the electronic module 11, preventing it from being affected by the high temperature of the heating compartment 8 and ensuring the stable operation of the MCU control unit 17.
[0064] II. Component Replacement 2: Bottle Changing Principle
[0065] Gas cylinder 7 installation:
[0066] Two sets of elastic clamps with a tensile strength of ≥50N are symmetrically installed inside the warehouse to hold a 1kg gas cylinder 7 with a diameter of 7cm. The hinged door panel 6 opens at an angle of ≥180° to achieve a quick one-handed bottle change in 30 seconds.
[0067] Sealing mechanism:
[0068] The sealing strip 15 on the inner side of the door panel 6 is tightly fitted to the edge of the opening of the box 1, forming a physical sealing barrier. After a 3kPa air pressure test, the leakage rate is less than 5% in 5 minutes, ensuring the airtightness of the gas chamber 5.
[0069] III. Heat Exchange Principle of Heating Component 3
[0070] Combustion heating:
[0071] Gas cylinder 7 supplies gas to fire plate 9 through a pipe. The perforated fire plate 9 has 1mm diameter holes spaced 5mm apart to evenly distribute the flame. It heats the outer spiral copper tube ring 10 with a 10mm diameter tube and a spiral height of 15cm, providing an effective contact area of 2000cm². 2 The thermal efficiency reaches 88%;
[0072] Thermal insulation:
[0073] The inner wall of the heating chamber 8 is covered by a heat insulation cover 20 that encloses the fire plate 9 and the copper tube ring 10. The ceramic fiber material has a density of 128 kg / m³. 3 Heat is concentrated in the heating area, while the heat-insulating steel plate 16 prevents heat from being conducted to the gas chamber 5, ensuring that the surface temperature of the gas cylinder 7 is ≤40℃;
[0074] Exhaust gas emissions:
[0075] The exhaust gas produced by combustion is discharged through the exhaust pipe 21 with an inner diameter of 3cm. The top windproof cap 22 has a wind speed resistance of ≥10m / s to prevent backflow and forms a directional exhaust channel.
[0076] IV. Adjustment Principle of Intelligent Control Component 4
[0077] Temperature control logic
[0078] Signal acquisition:
[0079] The water outlet pipe 24 has a water temperature sensor 25 with an accuracy of ±0.5℃ and a response time of ≤2 seconds. It monitors the water temperature in real time and converts it into an electrical signal, which is then transmitted to the MCU control unit 17 of the electronic module 11.
[0080] Command output:
[0081] The MCU compares the target temperature with the real-time temperature, which is set by the temperature adjustment knob 12 (range 30-60℃, accuracy 1℃). It also controls the gas proportional valve via PWM signal to adjust the accuracy by ±2% and dynamically adjusts the firepower of the burner 9 to ensure that the water temperature deviation is ≤ ±1℃.
[0082] Human-computer interaction:
[0083] The gas fire control switch 13 provides 5 power levels with a step size of 100W, and the temperature display 14 displays the water temperature in real time with a resolution of 0.1℃, as well as fault codes such as E01 indicating an oxygen concentration of <18%.
[0084] Circuit control principle
[0085] Relay group 19: Implements dual circuit protection. When the flow switch is triggered if the water flow rate is <0.5L / min or the oxygen concentration is abnormal, the gas solenoid valve and heating circuit are cut off within 0.5 seconds.
[0086] Wireless communication module 18: Supports Bluetooth / Wi-Fi connectivity, allowing users to remotely set the temperature and view the operating status via a mobile app, thus expanding intelligent control scenarios.
[0087] V. Working Principle of Water System
[0088] Water flow path:
[0089] Cold water flows in from the bottom left side of the box 1 through the inlet pipe 23, absorbs the heat of the fire plate 9 through the spiral copper tube ring 10, and flows out from the bottom right side through the outlet pipe 24, forming a "bottom inlet and top outlet" convection structure to improve heat exchange efficiency.
[0090] Safety precautions:
[0091] The pipeline uses explosion-proof flexible hoses with a pressure resistance of 1.6MPa. A rubber sealing sleeve with a waterproof rating of IP65 is installed at the point where it penetrates the box to prevent water leakage. The water outlet pipe 24 and temperature sensor 25 provide real-time feedback on the water temperature to avoid the risk of overheating and scalding.
[0092] VI. Multi-component collaborative workflow
[0093] Start-up phase:
[0094] When the 12V vehicle power supply / lithium battery is connected, the electronic module 11 initializes, the temperature display 14 shows the standby status, and the user sets the target temperature through the knob 12.
[0095] Heating stage:
[0096] The MCU control unit 17 starts the gas proportional valve, and the gas is burned through the pipeline to the burner 9. The copper pipe ring 10 heats the water flow, and the temperature sensor 25 provides real-time feedback data to form a closed-loop control.
[0097] Security Response:
[0098] If the oxygen sensor integrated in the electronic module 11 detects a concentration of <18%, the relay group 1 will cut off the gas supply within 190.5 seconds, the temperature display 14 will flash E01, and the buzzer will sound an alarm.
[0099] Shutdown phase:
[0100] When the gas power switch 13 is turned off, the gas supply is cut off, and the electronic module 11 enters sleep mode, reducing energy consumption to ≤10mA.
[0101] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
