The embodiment discloses a foaming method of an electric water heater, which is applied to the foaming tool of the electric water heater, and the foaming method comprises the following steps:

starting a start button, driving the upper fetal membrane 210 to ascend by the top plate 120, and moving the lower fetal membrane 220 out of the position right below the upper fetal membrane 210;

placing an electric water heater to be foamed in the lower tire membrane 220;

if the first distance measuring device 310 detects that the electric water heater to be foamed is put in, the subsequent process is executed, and if the first distance measuring device 310 does not detect that the electric water heater to be foamed is put in, the subsequent process is not executed;

the lower tire membrane 220 drives the electric water heater to be foamed to move to the position right below the upper tire membrane 210, and the top plate 120 drives the upper tire membrane 210 to descend;

if the second distance measuring device 320 detects that the upper and lower tire membranes 210 and 220 are close to each other and the mold is closed, the subsequent process is performed, and if the second distance measuring device 320 detects that the upper and lower tire membranes 210 and 220 are not close to each other, the subsequent process is not performed;

foaming was started.

If the third distance measuring device 330 detects that a foreign object is close to the foaming tool and the distance reaches the safety distance set by the system in the foaming process, the system controls the foaming to stop, gives an alarm, and continues foaming after the foreign object is far away from the foaming tool.

And the foaming tool automatically opens the die after foaming is finished according to the set time of the timing module, and sends a die opening prompt to a user.

When the mold is opened, the top plate 120 drives the upper tire membrane 210 to rise;

the lower tire membrane 220 drives the foamed electric water heater to move out from the position right below the upper tire membrane 210;

the foamed electric water heater is taken out from the lower tire casing 220.

In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
