Title:
LIQUID STORAGE BOX, DISPENSING MODULE, AND LAUNDRY TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/121925
Kind Code:
A1
Abstract:
A liquid storage box, a dispensing module and a laundry treatment apparatus. The liquid storage box (2) is internally provided with a sealed chamber (7) for storing an additive, and the liquid storage box (2) is further provided with an electrically conductive detection portion capable of detecting liquid level information of the internal additive. A dispensing module (1) is provided with the liquid storage box (2) and a liquid level detection module; when the liquid storage box (2) is placed in the dispensing module (1), the liquid level detection module is in contact with and electrically connected to the electrically conductive detection portion, and the liquid level information of the additive in the liquid storage box (2) is determined by a feedback signal output by the liquid level detection module. An electrically conductive probe (6) of the liquid storage box (2) and the liquid storage box (2) have an integrated structure, solving the problems that the assembly of the existing liquid storage box (2) and the electrically conductive probe (6) is complex, the additive is easy to leak caused by poor sealing between the existing liquid storage box (2) and the electrically conductive probe (6), and the liquid storage box (2) cannot be continuously used after the electrically conductive probe (6) is removed. The liquid storage box (2) has higher integrity, independent usability and reliability.
