[0023] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] In the present utility model, unless otherwise stated, directional words contained in terms such as "up, down, left, right, front, back, inside, outside" merely represent the orientation of the terms in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the terms.

[0025] See also Figure 1-3 The stratified heating electric water heater shown in the figure comprises a horizontally placed tank body 1, one end of the tank body 1 is provided with an opening 8, a flange cover plate 9 is installed at the opening 8, a plurality of electric heating rods 11 extending laterally into the tank body 1 are installed on the flange cover plate 9, a plurality of insulation plates 2 are arranged in a staggered manner in the tank body 1 along its length direction, a flow gap is formed between the insulation plates 2 and the top wall or the bottom wall of the tank body 1, the insulation plates 2 located at both ends are fixedly connected to the bottom wall of the tank body 1, a plurality of jacks for passing the electric heating rods 11 are provided on the insulation plates 2, an inlet water nozzle 5 is provided at the bottom of the tank body 1 between the flange cover plate 9 and the insulation plate 2 adjacent thereto, and an outlet water nozzle 4 is provided between the tail end of the tank body 1 and the insulation plate 2 adjacent thereto.

[0026] Through the implementation of the above technical solution, when the water heater is used, cold water enters from the inlet nozzle 5 and flows through multiple adjacent insulation boards 2 in an S-shaped fold. Each time it flows upward or downward, it passes through the electric heating rod 11 for heating, so that the water temperature can be gradually heated during the flow process, and finally flows out from the outlet nozzle 4 for use. Since the layered heating electric water heater divides the tank body 1 space into a continuous S-shaped folded multi-section structure, the water inlet area and the water outlet area are separated to form an S-shaped water flow path 3, so that the cold water will not suddenly flow to the water outlet area when the user is using the water, so that the water temperature is more stable.

[0027] In this embodiment, a spoiler baffle 6 is provided above the inlet water nozzle 5, one side of the spoiler baffle 6 is fixedly connected to the adjacent insulation board 2, and the other side is fixedly connected to the inner wall of the tank body 1, and a plurality of spoiler holes 7 are provided on the spoiler baffle 6. The spoiler baffle 6 blocks the incoming water flow so that the water flow can only flow upward from the spoiler baffle, thereby disturbing the water flow and increasing the mixing property of the water flow, thereby increasing the heating efficiency.

[0028] In this embodiment, the spoiler holes 7 are arranged through the spoiler baffle 6, and the extension direction of each spoiler hole 7 is different. By setting the spoiler holes 7 with different extension directions, the water flows flowing out of the spoiler holes 7 collide with each other, generating disturbances, thereby increasing the heating efficiency of water.

[0029] In this embodiment, an electric heater 12 is installed on the outer side of the flange cover plate 9, and the electric heating rod 11 is electrically connected to the electric heater 12 after passing through the flange cover plate 9, and the electrode 10 of the electric heater 12 extends outward to be connected to an external power source. The end of the electric heating rod 11 can be configured to be snap-fitted and connected to the preset snap-fit ​​holes on the flange cover plate 9, and the positive and negative electrodes of the electric heating rod 11 are respectively connected to the positive and negative electrodes of the electric heater 12, and the electric heater 12 is used for regulating the heating temperature, and is connected to an external power source through the electrode 10 extending outward.

[0030] In this embodiment, in order to further provide a method for installing the flange cover 9, a plurality of screws 13 are circumferentially arranged on the outer side of the opening 8, mounting holes corresponding to the screws 13 are arranged on the flange cover 9, and a nut 14 is sleeved on the outer end of the screw 13.

[0031] In addition, this arrangement also facilitates the overall disassembly of the plurality of electric heating rods 11 . After the flange cover 9 is disassembled, the electric heating plate can be pulled out from the socket on the insulation plate 2 .

[0032] In this embodiment, a plurality of the electric heating rods 11 are arranged in a rectangular shape in the tank body 1. Through such an arrangement, the heating effect of the electric heating rods 11 is improved.

[0033] In this embodiment, the plurality of electric heating rods 11 are arranged in 2-3 rows, 4-10 rows. The number of rows is set to be greater than the number of rows, so that a larger heating area of ​​the transverse plane can be covered, and as much water flow from bottom to top as possible can be directly heated.

[0034] See also Figure 4 As shown, the multiple insulation plates 2 in the utility model can be arranged near one end of the flange cover plate 9. For example, the multiple insulation plates 2 are arranged in the right half of the tank body 1 so that a larger volume of hot water can be left in the water outlet area of ​​the left half, which is convenient for users to use.

[0035] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
