Description

Technical Field

[0001] This utility model relates to the field of water heaters, and more particularly to a gas water heater. Background Technology

[0002] In scenarios with high water demand, such as large villas, traditional gas water heater systems typically rely on insulated water tanks to provide a stable supply of hot water. However, this approach has significant limitations. In actual installation, the hot water outlets of multiple gas water heaters must be connected to the insulated water tank, which then supplies water to each terminal. This connection method not only makes the layout of water and gas pipes complex and requires extensive piping work, significantly increasing the installation workload and construction difficulty, but also complicates the operation. Furthermore, the bulky size of the insulated water tank, coupled with the need to reserve maintenance space around it, severely encroaches on limited spaces such as villa basements and equipment rooms, greatly restricting the rational layout planning of the area.

[0029] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0030] See Figure 1 This utility model discloses a gas water heater, comprising: at least two water heater bodies, the at least two water heater bodies including a first water heater body 10 and a second water heater body 20, the first water heater body 10 being provided with a first heating element 11 and a first heating chamber, the first heating chamber having a first water inlet and a first water outlet, the first water inlet being used to introduce water flow and the first water outlet being used to guide water flow out; the second water heater body 20 being provided with a second heating element 21 and a second heating chamber, the second heating chamber having a second water inlet and a second water outlet, the second water inlet being used to introduce water flow and the second water outlet being used to guide water flow out.

[0031] In addition, it also includes a flow guiding component, which includes a first water outlet pipe 31, a second water outlet pipe 32, and a manifold pipe 33. The first water outlet is connected to the manifold pipe 33 via the first water outlet pipe 31, and the second water outlet is connected to the manifold pipe 33 via the second water outlet pipe 32. A flow divider is also included, which is connected to the manifold pipe 33. The flow divider has multiple liquid distribution holes, which are used to guide the fluid out.

[0032] Based on the above structure, during use, an external water source can be connected to the first and second water inlets via pipes to introduce external cold water into the first and second heating chambers respectively. Then, the first heating element 11 and the second heating element 21 are activated to heat the cold water in the first and second heating chambers. Subsequently, the heated hot water in the first heating chamber flows through the first outlet and the first outlet pipe 31 into the manifold 33; simultaneously, the heated hot water in the second heating chamber also flows through the second outlet and the second outlet pipe 32 into the manifold 33. After the two streams of hot water mix in the manifold 33, they are directly transported to the distribution component, which distributes the hot water through multiple distributing holes to multiple water terminals (such as kitchens and bathrooms).

[0033] In this way, there is no need to install a traditional insulated water tank and supporting circulation pipeline. Hot water is distributed to multiple water terminals through the manifold 33 and the diverter, which not only saves installation space (no need to reserve space for a water tank and maintenance area), but also eliminates the complicated procedures of water tank installation and pipeline laying, making installation more convenient and improving installation efficiency. At the same time, in the later maintenance, only the main body of the heater or the diverter needs to be inspected, making maintenance more convenient.

[0034] In addition, when the water demand is small, only one water heater body (such as the first water heater body 10) can be turned on. Cold water enters the first heating chamber through the first inlet, is heated by the first heating element 11, and then flows into the manifold 33 through the first outlet pipe 31, and is then transported to the terminal through the diverter. When the water demand increases, multiple water heater bodies can be turned on at the same time (such as the first and second water heaters working at the same time). The hot water from the two water heaters mixes in the manifold 33, doubling the total flow rate to meet the needs of large-flow water use (such as multiple faucets being turned on at the same time).

[0035] Compared to the traditional method of using a water tank for continuous heat preservation combined with a water heater, the gas water heater in this embodiment can be flexibly adjusted according to actual needs. For example, when only sporadic water usage is required, a single water heater unit is sufficient to meet the user's needs, avoiding gas waste caused by multiple units running simultaneously and saving energy. At the same time, the tankless design avoids the energy consumption of "reheating the entire tank of water after the water temperature drops" in traditional solutions, further saving energy.

[0036] It should be noted that in this embodiment, both the first water heater body 10 and the second water heater body 20 adopt existing combustion-type heating structures. Their core components include a burner (such as a cast iron burner or an aluminum burner) and a heat exchanger (such as a copper finned tube structure, with water flowing inside the tube and the outside receiving flame heating). The heat exchanger is positioned close to the burner. In this case, the burner and heat exchanger together form the first heating element 11 and the second heating element 21, while the first heating chamber and the second heating chamber are water flow channels formed within the heat exchanger pipes. During heating, the gas is ejected through the nozzle and mixes with air inside the burner, igniting the mixture. The flame heats the heat exchanger tube wall, and cold water absorbs heat and rises in temperature as it flows through the tube, thus achieving heating.

[0037] In addition, the first water outlet pipe 31, the second water outlet pipe 32, and the manifold 33 can be made of existing copper pipes, stainless steel pipes, or plastic pipes, respectively. During assembly, the first water outlet pipe 31 and the second water outlet pipe 32 can be connected to the manifold 33 through connectors; alternatively, a tee fitting can be installed at the inlet of the manifold 33 to connect the first water outlet pipe 31 and the second water outlet pipe 32.

[0038] More specifically, the diversion component in this embodiment can be an existing diversion device (such as a water manifold) or a multi-way valve (such as a three-way valve, four-way valve, etc.). By connecting water pipes to multiple dispensing holes of the diversion component, hot water can be directed to multiple water terminals (such as the kitchen, bathroom, etc.). In practical applications, the diversion component needs to be selected according to the number of water terminals and flow requirements, and sealing rings, clamps, and other accessories should be used at the interface to prevent leakage.

[0039] Furthermore, the flow guiding component includes a first water inlet pipe 34 and a second water inlet pipe 35, wherein the first water inlet pipe 34 is connected to the first water inlet and the second water inlet pipe 35 is connected to the second water inlet.

[0040] During installation, the first inlet pipe 34 is connected to an external water source to guide water flow through the first inlet and into the second heating chamber. Similarly, the second inlet pipe 35 is connected to an external water source to guide water flow through the second inlet and into the second heating chamber. By guiding water flow through two independent pipes, the water pressure in each water heater unit remains consistent, avoiding uneven flow distribution.

[0041] Furthermore, this embodiment also includes two flow detectors 40. During assembly, one flow detector 40 is connected to the first water inlet pipe 34, and the other flow detector 40 is connected to the second water inlet pipe 35.

[0042] In practical use, when the flow detector 40 at the first inlet pipe 34 detects a water flow signal exceeding a preset flow value, it transmits the signal to the backend control system. At this time, the backend system starts the first water heater body 10 connected to the first inlet pipe 34. Similarly, when the flow detector 40 at the second inlet pipe 35 detects a water flow signal exceeding a preset flow value, it transmits the signal to the backend control system. At this time, the backend system starts the first water heater body 10 connected to the second inlet pipe 35. Thus, both water heater bodies can only start when the flow detector 40 detects a water flow signal greater than the preset start-up signal, avoiding the probability of dry burning and equipment damage caused by starting the two water heater bodies when the water flow is too low, and indirectly improving the service life of the equipment.

[0043] It should be noted that the flow detector 40 can be an existing electromagnetic flow detector 40, turbine flow detector 40, or ultrasonic flow detector 40, etc.

[0044] Furthermore, a first temperature detector 50 is provided on the first water inlet pipe 34 and the second water inlet pipe 35 respectively, and the first temperature detector 50 is used to detect the temperature.

[0045] Specifically, when the first temperature detector 50 monitors the cold water inlet temperature in real time and finds it too low, the operator or the background control system can adjust the heating power of the first water heater body 10 or the second water heater body 20 based on the feedback temperature signal, increase the gas supply, and improve the heating power so that the outlet water temperature can still reach the set value.

[0046] Similarly, when a high temperature is detected, the power of the first water heater body 10 or the second water heater body 20 can be reduced again to reduce gas consumption, lower power, and avoid overheating and wasting energy.

[0047] Specifically, the first temperature detector 50 can be an existing thermocouple temperature detector, a resistance temperature detector, or a semiconductor thermistor temperature detector.

[0048] Furthermore, it also includes a diversion pipe 36. The flow guiding assembly includes the diversion pipe 36, which is provided with a third inlet and a third outlet. The third inlet guides the water flow in, and the third outlet is provided with a first reversing valve. The first reversing valve has a first interface, a second interface, and a third interface that are interconnected. The first interface is connected to the outside, the second interface is connected to the first inlet pipe 34, and the third interface is connected to the second inlet pipe 35.

[0049] Specifically, the third inlet is connected to the external water circuit, allowing the water to flow into the diversion pipe 36. Subsequently, the water flows through the first port of the first reversing valve to the second and third ports (e.g., in a three-way configuration), so that the water flow is split into two paths and enters the first inlet pipe 34 and the second inlet pipe 35 respectively, thus meeting the water demand and reducing the probability of uneven flow caused by resistance differences in traditional parallel pipelines.

[0050] It should be noted that the first directional valve can be an existing three-way valve (such as an electric three-way valve or a manually switching three-way valve) or a solenoid directional valve, depending on the actual needs.

[0051] In addition, the manifold 33 has an inlet and an outlet. A second reversing valve is provided at the inlet. The second reversing valve has a fourth, a fifth, and a sixth interface that are interconnected. The sixth interface is connected to the inlet. Thus, when the fourth interface is connected to the first outlet pipe 31, the water flow in the first outlet pipe 31 can be introduced into the manifold 33. At the same time, when the fifth interface is connected to the second outlet pipe 32, the water flow in the second outlet pipe 32 can also flow into the manifold 33. This allows the hot water from the first outlet pipe 31 and the second outlet pipe 32 to be concentrated and collected through the second reversing valve, and then distributed to multiple water terminals through the diverter at the outlet.

[0052] Similarly, the second directional valve can also be an existing three-way valve (such as an electric three-way valve or a manually switching three-way valve) or a solenoid directional valve.

[0053] Furthermore, a second temperature detector 60 is provided on the first water outlet pipe 31 and the second water outlet pipe 32 respectively, and the second temperature detector 60 is used to detect the temperature.

[0054] Specifically, the second temperature detector 60 can detect the water temperature of the heated water in the first water outlet pipe 31 and the second water outlet pipe 32 in real time. When the water temperature reaches the temperature required by the user, the operator or the back-end control system can shut down the first water heater body 10 and the second water heater body 20 to avoid the water heater from continuously keeping the water warm or repeatedly heating it, thereby reducing gas consumption and saving energy.

[0055] It should be noted that the first temperature detector 50 can be an existing thermocouple temperature detector, a resistance temperature detector, or a semiconductor thermistor temperature detector.

[0056] Furthermore, in this embodiment, the gas water heater also includes a housing 70, which has an installation cavity 71. The first water heater body 10, the second water heater body 20, and the flow guiding component are installed in the installation cavity 71. The housing 70 protects the first water heater body 10, the second water heater body 20, and the flow guiding component from external dust or impurities, so as to prevent them from being contaminated and affecting the normal use of each component.

[0057] Specifically, the housing 70 is provided with multiple mounting holes, which are connected to the mounting cavity 71 so that pipes (such as manifold 33 or branch pipe 36) can be introduced into or out of the mounting cavity 71 through the multiple mounting holes; of course, the mounting holes can also be structures used to install bolts, screws or flanges to fix the pipes.

[0058] Furthermore, the first heating element 11 includes a first burner and a first air inlet pipe, the first air inlet pipe being connected to the first burner; the second heating element 21 includes a second burner and a second air inlet pipe, the second air inlet pipe being connected to the second burner.

[0059] Specifically, the first burner can be connected to an external gas tank via a first intake pipe to allow gas to be introduced into the first burner for normal operation. Similarly, the second burner can be connected to an external gas tank via a second intake pipe to enable the second burner to operate normally.

[0060] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
