The water quantity detection assembly comprises a first temperature sensor 4 and a second temperature sensor 5. The first temperature sensor 4 is installed on the water outlet pipe 3 and used for detecting the real-time temperature of the water outlet pipe 3 so as to judge whether the electric water heater generates a bathing water signal or not and judge whether the total amount of the bathing water is increased to the amount of the inner container 11 or not. The second temperature sensor 5 is installed in the middle of the inner container 11 and is used for detecting the real-time temperature in the middle of the inner container 11 so as to judge whether the total amount of the bathing water is increased to half of the amount of the inner container 11.
Referring to fig. 2, specifically, the steps of determining whether the electric water heater has a bathing water signal and determining whether the total amount of the bathing water is increased to a half of the inner container 11 by using the first sensor and determining whether the total amount of the bathing water is increased to a half of the inner container 11 by using the second sensor are as follows:
s1: electrifying the electric water heater;
s2: the second temperature sensor 5 detects the temperature of the water outlet pipe 3;
s3: judging whether the temperature rise delta T1 of the water outlet pipe 3 is greater than or equal to a first temperature threshold delta Ts1, entering S4 if the temperature rise delta T1 of the water outlet pipe 3 is greater than or equal to the first temperature threshold delta Ts1, and returning to S2 if the temperature rise delta T1 of the water outlet pipe 3 is smaller than the first temperature threshold delta Ts 1;
s4: the system judges that a bathing water signal appears, enters a water consumption statistical mode and detects the water temperature in the middle of the inner container 11 by the first temperature sensor 4;
s5: judging whether the temperature drop delta T2 of the water temperature in the middle of the inner container 11 is greater than or equal to a second temperature threshold delta Ts2, entering S6 if the temperature drop delta T2 of the water temperature in the middle of the inner container 11 is greater than or equal to the second temperature threshold delta Ts2, and returning to S4 if the temperature drop delta T2 of the water temperature in the middle of the inner container 11 is less than the second temperature threshold delta Ts 2;
s6: the system judges that the total bathing water amount reaches half of the water amount of the inner container 11, stores the water amount in a chip of the display operation structure 9, and then detects the temperature of the water outlet pipe 3 by the second temperature sensor 5;
s7: judging whether the temperature drop delta T3 of the water outlet pipe 3 is greater than or equal to a third temperature threshold delta Ts3, if the temperature drop delta T3 of the water outlet pipe 3 is greater than or equal to the third temperature threshold delta Ts3, entering S8, and if the temperature drop delta T3 of the water outlet pipe 3 is smaller than the third temperature threshold delta Ts3, returning to S6;
s8: the system judges the total amount of the bath water to increase the water amount of the half inner container 11 again, and continuously stores the water amount in the chip of the display operation structure 9 so as to accumulate the water amount.
Optionally, the second temperature sensor 5 is mounted on the electrothermal tube 7, so that the second temperature sensor 5 can be mounted conveniently, and a mounting structure is not required to be additionally arranged in the liner 11 for fixing the second temperature sensor 5, so that the structure is simple.

Specifically, the principle by which the first temperature sensor 4 and the second temperature sensor 5 can be used to detect the amount of water in the inner bladder 11 is as follows:
because the density of hot water is lower than that of cold water, the height of the water outlet of the water inlet pipe 2 in the electric water heater is lower than that of the water inlet of the water outlet pipe 3. Therefore, in the operation process of the electric water heater, the electric heating tube 7 extending along the bottom of the inner container 11 firstly heats the water at the bottom of the inner container 11, and when the temperature rise of the water outlet pipe 3 measured by the first temperature sensor 4 is greater than or equal to the first temperature threshold value Δ T1, the electric water heater starts the shower operation. Then, the cold water entering the inner container 11 from the water outlet of the water inlet pipe 2 flows to the bottom of the inner container 11, and simultaneously, the hot water is slowly lifted to the top of the inner container 11. When the cold water rises to the position of the second temperature sensor 5, the water temperature detected by the second temperature sensor 5 is obviously reduced, so that when the water temperature reduction Δ T2 of the middle part of the inner container 11 is greater than or equal to the second temperature threshold value Δ Ts2, the water quantity in the inner container 11 at the moment is expressed to reach half of the amount of the inner container 11. When the cold water lifts the hot water to the top of the inner container 11, the hot water enters the water outlet pipe 3, so that when the temperature rise delta T3 of the water outlet pipe 3 measured by the first temperature sensor 4 is greater than the third temperature threshold delta Ts3, the water in the inner container 11 is increased by half the amount of the inner container 11 again. When the hot water is completely used up, the cold water flows through the water outlet pipe 3, so that when the temperature measured by the first temperature sensor 4 is obviously reduced, the hot water in the inner container 11 is completely used up.
Referring to fig. 3, optionally, in this embodiment, the detection result of the water amount in the inner container 11 may be used to perform a sterilization operation on the inner container 11, specifically, the sterilization step is as follows:
s10: electrifying the electric water heater;
s20: the system continuously detects the change of the accumulated water consumption;
s30: judging whether the total water consumption L is greater than or equal to a water quantity threshold Ls1, if the total water consumption L is greater than or equal to a water quantity threshold Ls1, entering S40, and if the total water consumption L is less than a water quantity threshold Ls1, returning to S20;
s40: the system enters a sterilization mode to sterilize the water in the inner container 11;
s50: judging whether the high-temperature sterilization temperature T is greater than or equal to a sterilization temperature threshold ts1, if the high-temperature sterilization temperature T is greater than or equal to a sterilization temperature threshold ts1, entering S60, and if the high-temperature sterilization temperature T is less than the sterilization temperature threshold ts1, returning to S40;
