Please refer to fig. 1-4.
As shown in fig. 1 to 4, the present embodiment provides a washing machine 1 including: a casing (not shown), an inner tub 10 provided in the casing, a controller (not shown), and a tub collision detecting device 20. The tub collision detecting device 20 includes a first detecting element 30 and a second detecting element 40, and the first detecting element 30 and the second detecting element 40 are electrically connected to a controller, respectively. The controller is used for controlling the rotation state of the inner tub 10 according to the touch state detected by the first and second detecting elements 30 and 40. The case is a structural member for loading the inner tub 10, and is generally in a regular shape such as a cylinder, but of course, the case may be in other irregular shapes, which is not limited thereto in this embodiment. The inner tub 10 is a container for placing clothes in the washing machine 1, and is generally in an open drum shape, the opening of the inner tub 10 is upwards arranged in the box body, the bottom of the inner tub is connected with a driving motor of the washing machine 1, and the washing and the clothes drying work is completed by means of rotation of the inner tub.
The first detecting element 30 is located outside the wall of the inner tub 10, and the first detecting element 30 is used for detecting a touch state between the outer wall of the inner tub 10 and the first detecting element. The first detecting element 30 is disposed at the outer side of the tub wall of the inner tub 10, and the first detecting element 30 is disposed at an interval from the outer side of the tub wall of the inner tub 10, and the interval may be set according to practical situations. The first detecting element 30 is disposed towards the outside of the tub wall of the inner tub 10, and the first detecting element 30 is used for detecting the touching state of the inner tub 10 and the first detecting element 30. The structure of the inner tub 10 for the first detecting element 30 may be selected in various ways, and in some embodiments, the outer side of the tub wall of the inner tub 10 is in a regular cylinder shape, and when the center of gravity of the inner tub 10 is not shifted, the inner tub 10 is stationary and rotated, and the distance between the inner tub 10 and the first detecting element 30 is constant.
The first detecting element 30 is not particularly limited, and may be an electronic element capable of detecting a touch state in the prior art. The detection of the touch state means that in the case where the inner tub 10 is in contact with the first detection element 30, the detection circuit of the first detection element 30 generates an electrical signal and transmits the electrical signal to the controller. Specifically, a touch switch may be employed in some embodiments, which is in a closed (or open) state without the inner tub 10 being in contact with the first sensing element 30; and is in an opened (or closed) state in the case where the inner tub 10 is in contact with the first sensing element 30, a signal is transmitted to the controller through the sensing circuit.
The second detecting element 40 is located above the inner tub 10, and the second detecting element 40 is used for detecting a touch state between the top of the inner tub 10 and the second detecting element 40.

Since it is only necessary to detect the displacement of the inner tub 10 in the axial direction of the rotation shaft 70 thereof, the "the second detecting element 40 is disposed above the inner tub 10" herein should be construed broadly, that is, the presence of a portion of the inner tub 10 under the second detecting element 40 is sufficient, and it is not required that the second detecting element 40 be located higher than the entire inner tub 10. Meanwhile, the selection of the second detecting element 40 is not particularly limited, and may be any element that can be used to detect a touch state in the prior art. By detecting a touch state, it is meant that the detection circuit of the second detection element 40 generates an electrical signal and transmits it to the controller in the case where the inner tub 10 is in contact with the second detection element 40, and in particular, a touch switch may be employed in some embodiments, and is in a closed (or open) state in the case where the inner tub 10 is not in contact with the second detection element 40; in an open (or closed) state when the inner tub 10 is in contact with the second sensing element 40, a signal is transmitted to the controller through the sensing circuit.

The third detecting element 50 is disposed toward the inner side of the tub wall of the inner tub 10, and the third detecting element 50 is used for detecting the touching state of the inner wall of the inner tub 10 and the third detecting element 50. The controller is used for controlling the rotation state of the inner tub 10 according to the touch states detected by the first, second and third detecting elements 30, 40 and 50.

Specifically, the third detecting element 50 is not particularly limited, and may be any element that can be used to detect a touch state in the prior art. By detecting a touch state, it is meant that the detection circuit of the third detection element 50 generates an electrical signal and transmits it to the controller in the case where the inner tub 10 is in contact with the third detection element 50, and in particular, a touch switch may be employed in some embodiments, and is in a closed (or open) state in the case where the inner tub 10 is not in contact with the third detection element 50; and is in an opened (or closed) state in the case where the inner tub 10 is in contact with the third sensing element 50, a signal is transmitted to the controller through the sensing circuit.
