[0036] The positioning plate 3 is disposed on one side of the outer shell 2, and an inner liner mounting groove 31 is provided on one side of the positioning plate 3. The inner liner mounting groove 31 is used to position and limit the heating inner liner 1.

[0037] On the other side of the positioning plate 3, there is an annular embedded wire groove 32; the embedded wire groove 32 extends along the edge of the positioning plate 3.

[0038] A wire plate groove 33 is provided below the positioning plate 3. The wire plate groove 33 is recessed towards the heating inner liner 1. A sloping step 331 is provided at the bottom of the wire plate groove 33. The sloping step 331 is used to install the circuit board.

[0039] The cover plate 4 is installed on the side of the outer shell 2 and is used to cover the positioning plate 3.

[0040] Specifically, in the prior art, the electric water heater needs to install the inner container, heating pipe, temperature controller and the like inside the shell 2, and needs to install the control circuit board and various power supply lines and data lines outside the inner container, so if a large-capacity inner container is needed, the shell 2 needs to be larger and longer in size to provide sufficient space for installing the circuit board and placing the power supply lines and the like, resulting in a relatively long length of the electric water heater and a high space occupancy rate, and a relatively high requirement for the installation space of the bathroom. In the embodiment, the positioning plate 3 is provided with an inner container installation groove 31, and the bottom surface of the groove is attached to the outer wall of the heating inner container 1. The positioning plate 3 is positioned and limited in the length direction to make the structure compact and shorten the body of the electric water heater. In addition, the other side of the positioning plate 3 is provided with a wire embedding groove 32. The other side needs to install a heating pipe, a temperature sensing element and the like in the heating inner container 1, and a large amount of power supply lines and the like are needed. When installing, the lines are compressed and placed in the wire embedding groove 32, and the space occupied by the lines is compressed in the positioning plate 3, so that the space inside the shell 2 can be effectively utilized. Furthermore, the wire plate groove 33 is arranged below the positioning plate 3, and the bottom of the wire plate groove 33 is provided with a beveled step 331. The inner side of the beveled step 331 is attached to the edge of the inner container, so that the edge of the inner container is arranged in a beveled manner, thereby further saving space. The control circuit board is installed parallel to the end surface of the beveled step 331, so that the control circuit board is also installed in an inclined manner. Compared with the vertical or horizontal installation mode, the inclined installation of the circuit board can further utilize the space, so that the structure is compact and the body of the electric water heater is shortened. The inner container installation groove 31, the wire embedding groove 32 and the wire plate groove 33 are arranged to effectively utilize the space, so that the length of the electric water heater is shortened, the space occupancy rate is reduced, and the requirement for the installation space of the bathroom is lowered, thereby facilitating installation.

[0041] Further, the outer side of the positioning plate 3 is also provided with a wire arranging plate 5, which is arranged above the wire embedding groove 32 in a ring shape. The wire arranging plate 5 is provided with a ring-shaped wire arranging groove 51, and the wire embedding groove 32 is provided with a wire passing hole 52 in communication with the wire embedding groove 32.

The wire arranging plate 5 is installed above the wire embedding groove 32, and the space of the wire embedding groove 32 is divided into two layers, so that the lines can be positioned and installed in two parts. One part can be fixed in the wire arranging groove 51, and the other part can enter the wire embedding groove 32 through the wire passing hole 52 for positioning and installation. The wire arranging plate 5 also has the effect of compressing the lines in the wire embedding groove 32 to prevent the lines from loosening.

[0043] Further, a plurality of wire pressing blocks 53 are arranged at the opening of the wire arranging groove 51, and the wire pressing blocks 53 are used to compress the lines.

[0055] Specifically, since the length of the wiring terminal 134 is relatively long, in order to further compress the space, the height of the connection end of the wiring terminal 134 and the wire is lowered and is closer to the direction of the positioning plate 3, in the embodiment, the L-shaped connecting piece 136 is installed at the connection end of the wiring terminal 134 and the wire, so that the wiring end of the wiring terminal 134 connected with the wire is converted to the second vertical section 1362 of the L-shaped connecting piece 136, the wire is connected with the second vertical section 1362 of the L-shaped connecting piece 136 and then is connected with the wiring terminal 134 through the first vertical section 1361 of the L-shaped connecting piece 136, the height of the connection of the wiring terminal 134 and the wire is further reduced, the space occupancy is reduced, the overall length of the electric water heater is shortened, and the consumer's installation space requirement in the bathroom is reduced.
