Referring to fig. 1 to 3, an embodiment of the present invention provides a water level detection system for a water storage box of a clothes treatment apparatus, including: the water storage box 100 is provided with a water storage cavity 111 and a water level detection cavity 112 which are transversely distributed and adjacently arranged, the volume of the water storage cavity 111 is larger than that of the water level detection cavity 112, and the water storage cavity 111 collects condensed water and allows the condensed water to overflow to the water level detection cavity 112 when reaching a full load state; the water level detecting apparatus includes a magnetic control sensor 300 and a magnetic float 200, wherein the magnetic float 200 is disposed in the water level detecting chamber 112 and floats up and down according to a change in the water level detecting chamber 112, and the magnetic control sensor 300 is disposed at a side of the water storage box 100 and detects the water level in the water level detecting chamber 112 by sensing the magnetic field intensity of the magnetic float 200.

The water storage box 100 is of a flat structure, the water level change of the water storage box is not obvious enough when the water storage box 100 is installed inside an electric appliance, the space in the water storage box 100 is divided into two liquid storage chambers, one of the two liquid storage chambers is a water storage cavity 111, the other one of the two liquid storage chambers is a water level detection cavity 112, the water storage cavity 111 is mainly used for storing condensed water, the capacity of the condensed water is larger than that of the water level detection cavity 112, after the condensed water in the water storage cavity 111 enters the water level detection cavity 112, the water level in the water storage cavity 111 rises obviously due to the fact that the capacity of the water level detection cavity 112 is smaller than that of the water storage cavity 111, the change of the magnetic floater 200 on the height position is also obvious, the water level detection precision of the water storage cavity 111 is greatly improved, and the detection precision requirement on the magnetic control sensor 300 can be reduced; when the water level in the water level detection chamber 112 changes, the height position of the magnetic floater 200 in the water level detection chamber 112 changes, the distance from the magnetic control sensor 300 also changes, and the magnetic control sensor 300 detects the position of the magnetic floater 200 according to the change of the magnetic field of the magnetic floater 200, so that the water level in the water level detection chamber 112 can be obtained.

Wherein, the water storage box 100 is separated into a water storage cavity 111 and a water level detection cavity 112 by a partition 101, the water level of the water storage cavity 111 is in a full load state when being leveled to the upper end of the partition 101, and the condensed water continuously entering the water storage cavity 111 can overflow into the water level detection cavity 112 when being in the full load state.

The water storage box 100 includes a top wall (not shown), the area corresponding to the water storage cavity 111 on the top wall is provided with a water inlet 120, and condensed water enters the water storage box 100, enters the water storage cavity 111 first, and does not enter the water level detection cavity 112, so that the detection of the magnetic float 200 by the magnetic control sensor 300 is not interfered.

A gap is formed between the upper end and the top wall of the partition plate 101, an overflow water level is defined by the upper end of the partition plate 101 in the water storage cavity 111 (the overflow water level refers to the water level of the water storage cavity 111 when condensate water in the water storage cavity 111 overflows to the water level detection cavity 112), when the water level of the condensate water in the water storage cavity 111 rises, the condensate water exceeding the upper end of the partition plate 101 enters the water level detection cavity 112, no gap or hole position for communicating the water storage cavity 111 with the water level detection cavity 112 is formed in the partition plate 101, and therefore the overflow water level defined by the upper end of the partition plate 101 is closer to the top wall of the water storage box 100, so that the water storage cavity 111 can receive more condensate water, and a user can be reminded of cleaning the condensate water in the water storage box 100 when the water level changes in the water level detection cavity 112.

The water level detection cavity 112 is located at the edge of the water storage box 100, so that the distance between the magnetic floater 200 and the magnetic control sensor 300 is relatively short, and the change degree of the magnetic field intensity is relatively large when the position of the magnetic floater 200 is changed, which is beneficial to the detection of the magnetic control sensor 300. Certainly, the water level detection cavity can be arranged in the water storage cavity and at any position which is not close to the edge, and the magnetic control sensor is arranged above or below the water storage box to detect the position of the magnetic floater.

The magnetic floater 200 is limited on both sides of the partition plate 101 in the transverse direction, and the displacement of the magnetic floater 200 in the length direction and the width direction of the water storage box 100 is limited, so that the magnetic floater 200 only moves in the height direction of the water storage box 100, only a small amount of position deviation exists in the transverse direction, and the influence on the detection result is small.

Further, the inner wall of the water level detection cavity 112 is provided with a plurality of limiting ribs 113 arranged along the height direction, the limiting ribs 113 contact with the magnetic floater 200 to limit the magnetic floater, the displacement of the magnetic floater 200 in the length direction and the width direction of the water storage box 100 can be further reduced, the accuracy of the detection result is improved, and therefore a user can correctly judge the water level condition in the water level detection cavity 112.

The corresponding structure is as follows: the guide rod is erected on the bottom wall of the water level detection cavity, a through hole capable of being matched with the guide rod is formed in the magnetic floater, and the guide rod limits the transverse displacement of the magnetic floater so that the magnetic floater can move up and down along the guide rod through the through hole.

The magnetic float 200 includes a magnet 210 and a floating block 220 enclosing the magnet 210, the magnet 210 has a magnetic field, the floating block 220 can move in the vertical direction along with the water level change in the water level detection chamber 112 while wearing the magnet 210, and the floating block 220 can not block the magnetic field and can not reduce the magnetic field strength, thereby not affecting the detection capability of the magnetic control sensor 300.

Referring to fig. 3 to 5, based on the above embodiments, the present embodiment specifically illustrates the changes of the magnetic sensor 300 and the magnetic float 200 when the water level in the water level detection chamber changes:

the magnetic control sensor 300 has an open state and a closed state, the distance between the magnetic control sensor 300 and the center of the magnet 210 is M, the magnetic control sensor 300 further has a detection range, the detection radius is H, the magnetic control sensor 300 senses the magnetic field intensity of the magnetic floater 200 to calculate the distance between the magnetic floater and the magnetic floater, and judges whether the magnetic floater 200 is in the detection range, so that the magnetic control sensor 300 is switched between the open state and the closed state, and the water level of the current water level detection cavity 112 can be judged according to the detection signal of the magnetic control sensor 300.

The following description is made in accordance with the accompanying drawings:

referring to fig. 5, as the condensed water continues to enter the water level detection chamber 112, the water level in the water level detection chamber 112 rises, and when the magnetic float 200 rises to M ═ H, the magnetic control sensor 300 is switched from the on state to the off state, and the water level in the water storage box 100 does not reach the overflow water level and has a certain margin, so that the user is left with sufficient time to process the condensed water.

If the prior art is adopted, when the condensed water does not overflow into the water level detection cavity, the magnetic control sensor is in a closed state, and if the magnetic control sensor fails, even if the condensed water enters the water level detection cavity to enable the magnetic floater to ascend, the magnetic control sensor cannot sense the water level detection cavity and is switched from the closed state to an open state; in the present invention, when the condensed water does not enter the water level detection chamber 112, the magnetic control sensor 300 is in the on state, so that it can be known whether the magnetic control sensor 300 can work normally, and when assembling, it can be detected in advance whether the magnetic control sensor 300 has a fault.
