Description

Technical Field

[0001] This utility model relates to the field of gas water heater technology, specifically a portable gas water heater with an auxiliary water tank. Background Technology

[0002] As is well known, there are many instant gas water heating systems on the market. However, most of these products lack a precise temperature control mechanism. This technical defect makes it difficult for users to obtain the expected water temperature output in scenarios such as washing and showering. The water temperature often becomes too hot, too cold, or fluctuates greatly. This not only affects the user experience but may also pose safety hazards due to sudden changes in water temperature. The common problem of insufficient temperature control accuracy in these products requires users to repeatedly adjust the water flow or gas valve to try to reach a suitable water temperature. This process is often accompanied by a large amount of water waste, which contradicts the current concept of energy conservation and environmental protection and fails to meet users' needs for a comfortable and convenient hot water supply.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3A portable gas water heater with an auxiliary water tank includes an integrated water tank 1. The upper half of the integrated water tank 1 has a cavity, and the lower half of the integrated water tank 1 has a working chamber. A water pump 5 is installed inside the working chamber, mounted on the inner wall of the working chamber. A gas heat exchanger 2 is also installed inside the working chamber. One end of the water pump 5 communicates with the interior of the cavity, and the other end of the water pump 5 communicates with the gas heat exchanger 2. A solenoid valve system 6 is installed on the water pump 5. A control panel 3 is located on one side of the integrated water tank 1, electrically connected to the water pump 5, the gas heat exchanger 2, and the solenoid valve system 6. A top cover 7 is located on the top of the integrated water tank 1. One side of the top cover 7 is hinged to the integrated water tank 1, and the other end of the top cover 7 is connected to the integrated water tank 1 via a central closing clamp.

[0019] In this embodiment, the top cover 7 can be opened and closed without any tools because there is a center clamp. The user can also change the hinge and the center clamp to allow the top cover 7 to open in the opposite direction. After opening the top cover 7, water is filled into the integrated water tank 1 (the integrated water tank 1 is fixedly provided with an inlet and an outlet. After filling with water, the hot water circulation system forms a closed loop). Then, the target water temperature is set through the control panel 3 and the heating program is started. The built-in water pump 5 will drive the water to circulate and heat in the gas heat exchanger 2. When the water temperature reaches the set value, the device will automatically stop heating.

[0020] When hot water is needed, the user presses the water pump button (water drop icon) on the control panel 3. The solenoid valve system 6 switches the water circuit, and the same circulating water pump 5 draws hot water from the outlet. The outlet is equipped with a quick connector, which can be easily connected to hoses, shower heads, or faucets. The specific operation procedure is as follows:

[0021] Water filling process: Open the top cover 7 and fill water into the integrated water tank 1 through the water inlet to ensure that there is no air residue in the closed system (the water can be filled to any level, it does not need to be completely full - the top cover 7 is equipped with a pressure relief valve, which allows air to enter the sealed integrated water tank 1, but the water will not leak).

[0022] Heating control: Set the water temperature (e.g., 42℃) on the control panel 3, press the heating button (flame icon), and the equipment will automatically ignite the burner. The water pump 5 drives the water to circulate through the heat exchanger to raise the temperature.

[0023] Thermostatic shutdown: When the temperature sensor detects that the water temperature has reached the set value, the burner automatically shuts off and the heating program stops;

[0024] Water pumping: Press the water pump button, the solenoid valve switches to water pumping mode, and the water pump pumps hot water from the outlet for washing or showering.

[0025] This design combines a closed-loop water circuit with a large-capacity integrated water tank and uses a gas heat exchanger to precisely control the temperature, avoiding water waste during temperature adjustment in traditional water heaters. The built-in water pump and solenoid valve system work together through software logic to achieve automated operation of "one-button heating and pumping". The water temperature can be precisely adjusted by degrees to meet the constant temperature water needs of outdoor showering, washing and other scenarios.

[0026] The gas heat exchanger 2 in the text is connected to an external gas tank. The gas flow is controlled by the solenoid valve system of the control panel 3. It is linked with the water temperature sensor to achieve constant temperature heating. The solenoid valve system 6 includes an inlet solenoid valve and an outlet solenoid valve. When heating, the inlet solenoid valve is opened to allow water to flow into the heat exchanger. When pumping water, it is switched to the outlet solenoid valve to drive the water to the outlet. A PT100 temperature sensor is installed in the cavity of the integrated water tank 1. The temperature measurement accuracy is ±0.5℃. It monitors the water temperature in real time and feeds it back to the control panel 3 to achieve precise constant temperature control.

[0027] In this embodiment, a filtration system 4 is installed inside the cavity and is fixed to the inner wall of the cavity by a bracket. The filtration system 4 consists of two different stainless steel filter screens with different mesh sizes. The water inlet of the filtration system 4 is connected to the water inlet at the top of the cavity, and the water outlet is directly connected to the water inlet of the water pump 5, forming a complete purification path of "water injection-filtration-heating-water outlet". This ensures that no impurities enter the pipeline system of the gas heat exchanger 2, avoids the problem of reduced heat exchange efficiency or pipeline blockage caused by the accumulation of impurities, and at the same time ensures the cleanliness of the water flowing out of the outlet, improving the water quality safety in scenarios such as washing and showering.

[0028] To improve the anti-slip effect between the equipment and the ground, this embodiment has an anti-slip layer fixedly connected to the bottom of the integrated water tank 1. The anti-slip layer is tightly bonded to the bottom of the integrated water tank using a molding process. Its surface is designed with an interlaced ribbed textured structure with a rib depth of 1.5-2mm, which can increase the friction coefficient with the ground and ensure that the equipment remains stable when placed in different scenarios such as campsites and RV platforms, avoiding displacement of the equipment due to vibration from water pump operation or external impact.

[0029] To enhance the anti-slip effect, the anti-slip layer in this embodiment uses high-quality rubber material with a moderate hardness of 60±5HA on the Shore A scale. This material ensures sufficient elasticity to adapt to the slight undulations of different ground surfaces while also possessing good wear resistance, maintaining its anti-slip effect over a long period. Its surface is treated with a special process to form a textured surface, which effectively increases the coefficient of friction with the ground. Even on wet or slippery surfaces, it significantly enhances the stability of the equipment when placed, preventing the equipment from sliding or shifting due to vibrations from the water pump or external impacts, thus providing users with a more reliable user experience.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
