Water purifier

Abstract

The invention relates to a water purifier. The water purifier comprises a shell, a filtering device arranged in the shell, and a water inlet pipe and a water outlet pipe which are respectively connected with the filtering device. The water purifier also comprises a water leakage detection device, comprising a water quality sensor with two electrode probes, a detection electrode with two electrodeprobes, and a control circuit board electrically connected with the water quality sensor and the detection electrode respectively. The water quality sensor is arranged in the water path, one electrodeprobe of the water quality sensor is electrically connected with one input end of the control circuit board, and the other electrode probe of the water quality sensor is grounded. The detection electrode is arranged at the water leakage detection position, one electrode probe of the detection electrode is electrically connected with the other input end of the control circuit board, and the otherelectrode probe of the detection electrode is grounded. The water purifier can effectively distinguish condensate water and water leakage conditions, further avoids false alarm of condensate water, and is accurate in water leakage detection and user-friendly in use.

Description

technical field [0001] The invention relates to a water purifier. Background technique [0002] A water leakage detection device is usually installed in the existing water purifier to detect the water leakage of the water purifier. For example, the Chinese utility model patent "A Water Purifier" with the authorized announcement number CN206613254U (application number CN201720150264.4), wherein the disclosed water purifier includes a housing and a water leakage detection assembly arranged at the bottom of the housing, so The water leakage detection assembly includes a detection plate and a first electrode and a second electrode arranged at intervals on the detection plate, and electrode rods are arranged on the first electrode and the second electrode. When leaking water flows out from different places on the bottom plate of the housing, the electrode rods 23 evenly distributed on the first electrode 21 and the second electrode 22 can detect the leaking water, and then give ...

AI Technical Summary

Problems solved by technology

The water leakage detection device detects water leakage through the conduction of the two electrodes, but in the process of use, there may also be condensed water, and often the appearance of condensed water is not caused by the sealing or failure of the water purifier. Under these circumstances, it is not required to do water leakage alarm work

However, if the aforementioned water leakage detection device is used, a water leakage alarm will also be performed in the case of condensed water, and false alarms of condensed water will often occur, and then guide users to maintain the water purifier and frequently disassemble the water purifier. The device is not conducive to the maintenance of the water purifier's own sealing and service life, and the maintenance cost is high
