For example, the limiting plate 530 is arranged on the right side of the accommodating cavity 101, the matching groove 521 is arranged at the position, corresponding to the float 510, on the outer side of the body 100, the induction plate 520 is matched in the matching groove 521, the reed pipe is arranged on the induction plate 520, the magnetic pipe is arranged on the float 510, and in the process that the float 510 moves up and down, the reed pipe and the magnetic pipe are mutually induced to enable the float 510 to communicate with the induction plate 520, so that the change of the liquid level of the consumable in the accommodating cavity 101 can be detected, and the state of the allowance of the consumable can be judged by detecting the change of the distance between the float 510 and the limiting plate 530.

For example, the consumable in the receiving chamber 101 may have three states of the remaining amount, including a state of sufficient remaining amount, a state of insufficient remaining amount, and a state of exhausted remaining amount, and when the float 510 is located at the highest position, that is, when the distance between the float 510 and the limiting plate 530 is the minimum, the consumable is in the state of sufficient remaining amount; when the float 510 is located at the lowest position, that is, the distance between the float 510 and the limit plate 530 is the largest, the consumable is in a state of residual consumption; when the float 510 is positioned between the uppermost position and the lowermost position, the consumables are in an insufficient amount state.

According to the dispenser 10 for a dishwasher of the embodiment of the present invention, the level of the consumables in the receiving chamber 101 is detected by the communication between the float 510 and the sensing plate 520, which float up and down, and the float 510 is restricted by the restriction plate 530, and the state of the remaining amount of the consumables can be determined by detecting the distance between the float 510 and the restriction plate 530.

According to some embodiments of the present invention, as shown in fig. 10, the lowest position of the float 510 is located above the lowest position of the accommodating chamber 101. Thus, when the float 510 is at the lowest position, that is, when the consumable is in the empty state, since the remaining liquid consumable is gathered to the lowest position of the accommodating chamber 101, the liquid consumable is still stored in the accommodating chamber 101 for at least one time of washing, thereby facilitating the use of the user.
