Description

Technical Field

[0001] This utility model relates to the field of storage equipment, and in particular to a constant temperature water heater. Background Technology

[0002] Existing gas water heaters are equipped with proportional valves to control the amount of gas entering the system.

[0003] For example, patent document CN116202215A discloses a gas water heater, including a shell, water circuit, gas circuit, burner, fume hood, and exhaust pipe. The gas water heater is installed upright on the ground or under a cabinet. This invention proposes a completely new form of gas water heater, breaking away from the current situation where gas water heaters are wall-mounted or protrude from the wall. This is achieved through the design of a completely new shell shape, inlet and outlet water pipes, proportional valve pipes, and fume hood top cylinder, among other structural features.

[0004] For example, patent document CN119146580A discloses a gas water heater and its control method. The gas water heater includes: a water supply pipeline; a burner for heating the water supply pipeline; a gas pipeline for supplying gas to the burner, wherein a gas proportional valve and the burner are connected in series along the airflow direction on the gas pipeline; and a controller for: responding to user operation, controlling a booster pump to pressurize the water flow in the water supply pipeline at a first head.

[0005] However, in the above technology, the gas enters the burner directly after passing through the proportional valve, resulting in uneven gas discharge and affecting combustion efficiency.

[0006] Therefore, a constant temperature water heater is proposed to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a constant temperature water heater that can make the gas flow evenly to the burner, thus having the advantage of complete combustion.

[0009] As a further improvement to the above technical solution, a flow sensor is provided at the air inlet of the proportional valve, and a temperature sensor is provided at the water outlet of the heat exchange tube.

[0010] As a further improvement to the above technical solution, the fire vent includes a mounting groove located between the openings of multiple pipes, and the gas distribution section is embedded in the mounting groove.

[0011] As a further improvement to the above technical solution, a positioning component is also included. The positioning component is sleeved outside the gas distribution section and is adapted to the installation groove. The bottom of the pipe is provided with a insert, and the positioning component is provided with a notch. When the positioning component is located in the installation groove, the insert is inserted into the notch.

[0012] As a further improvement to the above technical solution, a limiting rod is provided at the bottom of the pipe, a limiting plate is provided at the top of the mounting groove, and a first limiting hole and a second limiting hole are provided on the positioning component. When the positioning component is located in the mounting groove, the limiting rod and the limiting plate are respectively inserted into the first limiting hole and the second limiting hole.

[0013] As a further improvement to the above technical solution, the positioning component is provided with a fixing plate, and the air distribution part is provided with a fixing seat, and the fixing seat and the fixing plate are fixedly connected by bolts.

[0014] As a further improvement to the above technical solution, the fire vent is provided with a first bracket, which is fixedly connected to the outer casing.

[0015] As a further improvement to the above technical solution, the gas distribution section is provided with a second bracket, which is fixedly connected to the outer casing.

[0016] As a further improvement to the above technical solution, a handle is rotatably mounted on the top of the housing.

[0017] The beneficial effects of this utility model are: by setting up a gas distribution section, the gas can be burned evenly through the burner, ensuring combustion efficiency. At the same time, the gas distribution section is simple and convenient to install. Attached Figure Description

Gas enters the chambers 61 through the air inlet 63 and the connecting pipe 64, and then enters the pipes 41 of the burner 4 through the exhaust port 62 before being discharged for combustion, ensuring uniform gas flow and complete combustion.

[0030] In a preferred embodiment, a flow sensor (not shown) is installed at the air inlet of the proportional valve 5, and a temperature sensor (not shown) is installed at the water outlet of the heat exchange tube 3.
