Problems solved by technology

These three heating methods have their own advantages and disadvantages. Among them, the submerged heating method can only heat the water in the entire inner tank, and cannot be heated in a targeted manner. The heating time is long and there is a certain waste of energy consumption; Limited by the power, it cannot meet the user's bathing requirements when the inlet water temperature is low; the semi-tank heating method can heat the semi-tank water in a targeted manner, but the heating time is still too long compared with the top layer heating, and the heat output The amount of water is not as much as that of the submersible type

Embodiment 1

[0030] The embodiment of the present invention provides a heating element 1, which is used to heat the water in the inner tank of the water heater, such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the heating element 1 includes: a top layer heating tube 11 located at the top of the liner for heating water in the top layer of the liner; a middle layer heating tube located in the middle of the liner for heating the middle layer of the liner and the area above 12; Located at the bottom of the inner container, the bottom heating pipe 13 for heating the full water of the inner container. Since the specific gravity of hot water is smaller than that of cold water, hot water will flow upwards while cold water will flow downwards to generate convection. Therefore, the heating pipe will only heat the water located in this layer and above.

[0031] Using the heating element 1 provided in this embodiment, the controller can be used to control any combination of the abov...

Embodiment 2

[0039] On the basis of Example 1, as figure 1 As shown, further, the top layer heating tube 11 , the middle layer heating tube 12 and the bottom layer heating tube 13 all include: a resistance wire, a cold needle for conducting electricity, and a tube wall covering the resistance wire and the cold needle.

[0040] figure 1 In the structure of the heating element 1 shown, the top layer heating tube 11, the middle layer heating tube 12 and the bottom layer heating tube 13 all adopt respective tube wall structures, that is, the top layer heating tube 11, the middle layer heating tube 12 and the bottom layer heating tube 13 are all It consists of a set of resistance wires, cold needles and tube walls.

[0041] In this embodiment, it is also possible to adopt the structure that the top heating tube 11 and the bottom heating tube 13 share the same tube wall, that is, the resistance wires and cold needles of the top heating tube 11 and the bottom heating tube 13 are arranged in the ...

Embodiment 3

[0049] Embodiments of the present invention provide a water heater, such as Figure 6 As shown, it includes an inner tank 2 and a heating element 1 for heating the water in the inner tank 2. The heating element 1 includes: a top layer heating pipe 11 located on the top of the inner tank 2 for heating the water in the top layer area of ​​the inner tank 2; Located in the middle of the liner 2, it is used to heat the middle layer heating pipe 12 of the middle layer of the liner 2 and above; it is located at the bottom of the liner 2, and is used to heat the bottom heating pipe 13 of the inner liner full of water.

[0050] With the water heater provided in this embodiment, the controller can be used to control any combination of the above-mentioned several heating tubes to heat the water in the inner tank 2 of the water heater, that is, to heat one alone or several simultaneously.

[0051] The specific heating method is the same as the above embodiment, and will not be repeated he...

The heating element is used for heating water in the inner container of the water heater, and comprises a top layer of heating tubes which are arranged at the top part of the inner container, an intermediate layer of heating tubes which are arranged in the middle of the inner container, and a bottom layer of heating tubes which are arranged at the bottom of the inner container. The water heater comprises the inner container and the heating element for heating water in the inner container, wherein the heating element comprises the top layer of heating tubes which are arranged at the top part of the inner container, the intermediate layer of heating tubes which are arranged in the middle of the inner container, and the bottom layer of heating tubes which are arranged at the bottom of the inner container. The water heater and the heating element thereof disclosed by the invention are applicable to water storage heating household appliances.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a water heater and a heating element thereof. Background technique [0002] At present, the heating methods of water storage water heaters include the following three types: submerged type, top-layer type and semi-tank type. Among them, the submerged type is a heating method in which the heating tube is placed at the bottom of the inner tank; the top-layer type is a heating method in which the heating tube is placed The heating method on the top layer of the inner tank; the half tank type is a heating method in which the heating tube is set in the middle of the inner tank. These three heating methods have their own advantages and disadvantages. Among them, the submerged heating method can only heat the water in the entire inner tank, and cannot be heated in a targeted manner. The heating time is long and there is a certain waste of energy consumption; Limited by the power, it...
