Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically to a large-capacity, high-efficiency gas water heater distributor. Background Technology

[0002] Currently, most gas water heater distributors adopt a segmented structure. The gas intake of different segments is controlled by solenoid valves, which are in turn controlled by the main control unit of the gas water heater. The main control unit controls the opening and closing of the solenoid valves based on the inlet and outlet water temperatures of the water heater. The gas distribution device requires the installation of solenoid valves, and the main control unit of the water heater also needs to connect and control the solenoid valves. These structures make the internal structure of the water heater relatively complex. Relying solely on the on / off control of the solenoid valves to achieve segmentation cannot meet users' needs for precise control of the water heater. In addition, existing distributors lack a precise control mechanism for large-capacity applications, and the gas distribution uniformity is poor, affecting heating efficiency.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent document discloses a distributor and water heater [CN202123318532.4], which includes a body and an end cap. The end cap is disposed above the body and has a first chamber with an opening facing downwards and a second elastic member, the second elastic member being located inside the first chamber. The body contains a first valve seat, a first elastic member, and a first valve core. One end of the first valve core is disposed on the fluid inflow side of the first valve seat, and the other end of the first valve core is slidably disposed inside the first chamber and abuts against the second elastic member. Deformation of the first and second elastic members causes the first valve core to move axially within the first chamber.

[0004] The above solution has solved the problem of complex solenoid valve control structure in the distributor to some extent. However, the solution still has many shortcomings, such as the lack of a precise control mechanism for large volume requirements and poor uniformity of gas distribution, which affects heating efficiency. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned problems by providing a large-capacity, high-efficiency gas water heater distributor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large-capacity, high-efficiency gas water heater distributor, comprising an assembly frame, an air inlet pipe structure at one end of the assembly frame, a solenoid valve assembly at the bottom of the assembly frame, a gas distribution cavity connected to the air inlet pipe structure inside the assembly frame, and a gas recovery structure at the end of the assembly frame away from the air inlet pipe structure.

[0007] In the above-mentioned large-capacity high-efficiency gas water heater distributor, the gas inlet pipeline structure includes a main gas inlet pipe, the bottom of which is connected to an external gas supply device and the top of which is connected to a gas distribution chamber.

[0010] In the aforementioned large-capacity, high-efficiency gas water heater distributor, pressure balancing valves are installed on both the main gas inlet pipe and the gas distribution chamber.

[0011] In the aforementioned large-capacity, high-efficiency gas water heater distributor, a number of gas regulating chambers are provided within the gas distribution channel, and regulating valves controlled by solenoid valve assemblies are provided between adjacent gas regulating chambers.

[0012] In the aforementioned large-capacity, high-efficiency gas water heater distributor, the solenoid valve assembly includes a solenoid valve core for regulating the gas flow rate. The solenoid valve core is equipped with a temperature sensor, and the solenoid valve core is fixed to the lower side of the assembly frame via a valve seat bracket. A terminal block is provided at the lower end of the solenoid valve core.

[0013] In the aforementioned large-capacity, high-efficiency gas water heater distributor, the solenoid valve core is provided with several annularly arranged heat dissipation fins, which are connected by several longitudinally arranged heat spreaders.

[0014] In the aforementioned large-capacity, high-efficiency gas water heater distributor, the gas recovery structure includes a gas recovery chamber, which is connected to the gas outlet of the gas distribution chamber via a one-way valve pipe, and is also connected to the inlet of the recovery pipeline via a gas recovery pipe.

[0015] In the aforementioned large-capacity, high-efficiency gas water heater distributor, the gas recovery pipe is connected to each gas regulating chamber via an inlet branch pipe.

[0016] Compared with the prior art, the advantages of this utility model are as follows: First, it achieves precise control of large-volume demand through intake compensation, spiral air guiding and pressure balancing valve. Second, it improves the uniformity of gas distribution by means of multiple adjustment chambers and regulating valves. In particular, the precise adjustment of the solenoid valve assembly can adapt to changes in gas demand in large-volume scenarios in real time, enhance the control accuracy, and the gas recovery structure recycles and reuses the underutilized gas.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] like Figure 1-5 As shown, a large-capacity, high-efficiency gas water heater distributor includes an assembly frame 1, an air inlet pipe structure 2 at one end of the assembly frame 1, a solenoid valve assembly 3 at the bottom of the assembly frame 1, a gas distribution cavity 4 connected to the air inlet pipe structure 2 inside the assembly frame 1, and a gas recovery structure 5 at the end of the assembly frame 1 away from the air inlet pipe structure 2.

[0025] The intake pipeline structure 2 includes an intake main pipe 21, the bottom of which is connected to an external gas supply device and the top of which is connected to a gas distribution chamber 4. An intake compensation pipeline 22 is provided on one side of the intake main pipe 21, and the intake compensation pipeline 22 is connected to an external gas supply compensation device.

[0026] When the gas supply is insufficient, the external gas supply compensation device supplements the gas supply through the gas inlet compensation pipeline 22 to ensure the stability of the gas supply.

[0027] As can be seen, the intake manifold 21 is also provided with a recovery pipe inlet 23 connected to the gas recovery structure 5, and the recovery pipe inlet 23 is equipped with a solenoid valve 24.

[0028] Furthermore, the intake manifold 21 has a spiral air guide section 25 on its inner wall.

[0029] The gas supply equipment delivers gas to the gas distribution chamber 4 through the gas inlet pipe 21. The spiral gas guide section 25 on the inner wall of the gas inlet pipe 21 can guide the gas flow, making the gas flow more stable.

[0030] Furthermore, pressure balancing valves are installed on both the intake manifold 21 and the gas distribution chamber 4.

[0031] The pressure balancing valve is used to balance the intake pressure and prevent excessively high or low pressure from affecting the gas supply.

[0032] Specifically, the gas distribution channel 4 is provided with a number of gas regulating sub-chambers 41, and a regulating valve 42 controlled by the solenoid valve assembly 3 is provided between adjacent gas regulating sub-chambers 41.

[0033] The regulating valve 42 is controlled and regulated by the solenoid valve assembly 3. The opening degree of the regulating valve 42 is changed by the action of the solenoid valve core 31, thereby regulating the gas flow rate of each gas regulating chamber 41.

[0034] Multiple solenoid valve cores 31 are set here to achieve separate adjustment of each gas regulating chamber 41, so as to precisely control the intake air volume.

[0035] More specifically, the solenoid valve assembly 3 includes a solenoid valve core 31 for regulating the flow of gas. The solenoid valve core 31 is equipped with a temperature sensor 32, and the solenoid valve core 31 is fixed to the lower side of the assembly frame 1 by a valve seat bracket. A terminal block 33 is provided at the lower end of the solenoid valve core 31.

[0036] In detail, the solenoid valve core 31 is provided with a number of annularly arranged heat dissipation fins 34, and the heat dissipation fins 34 are connected by a number of longitudinally arranged heat dissipation plates 35.

[0037] Temperature sensor 32 is used to monitor temperature, and heat sink fins 34 and heat spreader 35 are used for efficient heat dissipation to prevent excessive temperature from affecting the normal operation of solenoid valve core 31.

[0038] Preferably, the gas recovery structure 5 includes a gas recovery chamber 51, which is connected to the gas outlet of the gas distribution chamber 4 via a one-way valve pipe 52, and the gas recovery chamber 51 is connected to the recovery pipeline inlet 23 via a gas recovery pipe 53.

[0039] The gas at the outlet of the gas distribution chamber 4 is connected to the burner premix chamber through a gas guide pipe, and the burner premix chamber is connected to the gas recovery chamber 51 through a residual gas outlet pipe.

[0040] In addition, the gas recovery pipe 53 is connected to each gas regulating chamber 41 via the intake branch pipe 54.

[0041] Unutilized gas in each gas regulating chamber 41 enters the gas recovery pipe 53 through the intake branch pipe 54, and eventually flows into the gas recovery chamber 51. When gas needs to be recovered and reused, the solenoid valve 24 opens, and the gas in the gas recovery chamber 51 enters the intake main pipe 21 through the gas recovery pipe 53 and the recovery pipe inlet 23. After mixing with the newly input gas, it is reused, improving the gas utilization rate.

[0042] In summary, the principle of this embodiment is as follows: gas is input through the gas intake main pipe 21, wherein the airflow is stabilized by the spiral gas guide section 25 during gas intake, the gas intake compensation pipe 22 ensures the continuity of gas supply, the gas is distributed through the regulating chamber 41 of the distribution channel 4, and the gas flow rate is precisely regulated by the regulating valve 42 controlled by the solenoid valve core 31. This provides a precise control mechanism for gas water heaters with large capacity requirements, improves the uniformity of gas distribution, and unused gas is collected through the recovery chamber 51 of the gas recovery structure 5 and returned to the gas intake main pipe 21 for reuse through the recovery pipe inlet 23, thereby improving heating efficiency.

[0043] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0044] Although this document frequently uses terms such as assembly frame 1, intake pipe structure 2, main intake pipe 21, intake compensation pipe 22, recovery pipe inlet 23, solenoid valve 24, spiral air guide 25, solenoid valve assembly 3, solenoid valve wire core 31, temperature sensor 32, terminal block 33, heat dissipation fins 34, heat spreader 35, gas distribution chamber 4, gas regulating chamber 41, regulating valve 42, gas recovery structure 5, gas recovery chamber 51, one-way valve pipe 52, gas recovery pipe 53, and intake branch pipe 54, the possibility of using other terms is not excluded.
