Description

Technical Field

[0001] This utility model relates to the field of water heaters, and in particular to a gas water heater using an instant electric heating element. Background Technology

[0002] Existing technology involves adding electric heating devices to gas water heaters to assist in heating the water.

[0003] For example, patent document CN112556194B discloses a gas water heater control method, a gas water heater, and a readable storage medium. The gas water heater control method includes: when the gas water heater is in N-stage heating mode, and the load on the gas water heater increases, first increasing the heating power of the burner in the gas water heater, and when the burner increases to the maximum heating power of the N-stage heating mode, activating the electric heating module in the gas water heater for auxiliary heating.

[0004] The above technologies solve the problem of loud water heater noise by relying on electric heating devices. However, when the power exceeds the machine's operating power or falls below the minimum starting load of the gas water heater, the gas water heater will fail and cannot start the water heater at the desired temperature at any time.

[0005] Therefore, a gas water heater using an instant electric heating element is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a gas water heater that uses an instantaneous electric heating element, which has the advantage of being able to operate normally when the power exceeds the machine's operating power or is below the minimum starting load of the gas water heater, thereby meeting the user's needs.

[0007] The technical solution adopted by this utility model to solve the problem is: a gas water heater using an instant electric heating element, comprising: a shell, a burner disposed inside the shell, a heat exchanger disposed on the top of the burner, a pipeline disposed outside the heat exchanger, an electric heating unit disposed inside the shell, the electric heating unit being connected to the pipeline, and a temperature sensor disposed on the pipeline.

[0008] As a further improvement to the above technical solution, the outer casing is provided with a water outlet, and a first flow sensor is provided at the water outlet.

[0009] As a further improvement to the above technical solution, the outer casing is provided with a water inlet, and a second flow sensor is provided at the water inlet.

[0010] As a further improvement to the above technical solution, one side of the outer casing is an opening, and a panel is provided at the opening.

[0011] As a further improvement to the above technical solution, the top and bottom of the panel are provided with folded edges, the top of the outer shell is provided with a first connecting ear, and the folded edge of the top of the panel overlaps the first connecting ear and is fixedly connected to the first connecting ear by bolts.

[0012] As a further improvement to the above technical solution, the bottom of the outer shell is provided with a second connecting ear, the second connecting ear is provided with a connecting post, and the bottom edge of the panel is provided with a socket, the socket being adapted to the connecting post.

[0013] The beneficial effects of this utility model are: by setting an electric heating unit and a temperature sensor, heating can be assisted, and normal use can be guaranteed when the set temperature is lower than the burner's starting power or higher than the burner's maximum power, thereby increasing the operating temperature range and meeting user needs.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0023] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 4 A gas water heater using an instant electric heating element includes: a casing 1, a burner 2 inside the casing 1, a heat exchanger 3 on top of the burner 2, a pipe 4 outside the heat exchanger 3, an electric heating unit 5 inside the casing 1, the electric heating unit 5 connected to the pipe 4, and a temperature sensor 10 on the pipe 4. This device is similar to a traditional gas water heater. The controller collects the temperature from the temperature sensor 10, and calculates the required power of the water heater based on the customer-set temperature. Analysis of the required power determines the following: when the customer-set temperature is lower than the inlet water temperature, neither the burner 2 nor the electric heating unit 5 starts; when the user-set temperature is higher than the inlet water temperature but lower than the minimum starting load of the burner 2, the electric heating unit 5 starts heating; when the user-set temperature is higher than the inlet water temperature and higher than the maximum power of the electric heating unit 5, the burner 2 starts heating; when the user-set temperature is higher than the inlet water temperature and higher than the maximum power of the burner 2, both the burner 2 and the electric heating unit 5 start heating simultaneously.

[0025] In a preferred embodiment, the outer casing 1 is provided with a water outlet 6, and a first flow sensor 7 is provided at the water outlet 6.

[0026] In a preferred embodiment, the outer casing 1 is provided with a water inlet 8, and a second flow sensor 9 is provided at the water inlet 8. The controller of the gas water heater can further calculate the required power based on the inlet and outlet water flow rates.
