When the cloth is clamped at the detecting device 40, the clothes are clamped between the door body 12 and the window pad 30, and after the clothes are clamped, the part of the clothes is located between the front detecting piece 41 and the rear groove wall 1122 of the first groove 112, and whether the clothes are clamped can be judged by detecting whether an obstacle or a foreign matter exists between the front detecting piece 41 and the rear groove wall of the first groove 112. Due to the front detection piece 41, whether cloth clamping occurs nearby can be detected only; in order to increase the improved accuracy, a plurality of detection devices 40 may be provided on the washing machine.

In this embodiment, the detecting device 40 further has a rear detecting member 42 fixed in the first groove 112, the front detecting member 41 has a telescopic column 411 capable of being extended back and forth, and the telescopic column 411 can be extended into the first groove 112. When the door 12 is in a closed state and no cloth is clamped, the telescopic column 411 contacts the rear detection piece 42; when the cloth is sandwiched between the detecting device 40 and the telescopic column 411, the cloth is spaced from the rear detecting member 42.

In this embodiment, the rear detecting member 42 is a reed pipe, a magnetic member 412 matched with the reed pipe is arranged in the telescopic column 411, and whether cloth is clamped or not is judged according to the distance between the reed pipe and the magnetic member 412. When the telescopic column 411 is in contact with the rear detection piece 42, the distance between the reed pipe and the magnetic piece 412 is D1; in the presence of the clamping cloth, the distance D2 between the reed switch and the magnetic element 412 is definitely larger than D1.

In order to further increase the detection accuracy and avoid whether clothes are clamped between the front detection piece 41 and the rear detection piece 42, the distance between the reed switch and the magnetic piece 412 is not changed greatly, especially when the clothes are thin; it should be provided that the distance between the front detecting member 41 and the rear detecting member 42 is increased in the presence of the cloth clip.

A protection block 43 is arranged in the first groove 112, an accommodating opening 431 is formed in the protection block 43, the rear detection piece 42 is positioned in the accommodating opening 431, and the rear end of the front detection piece 41 can extend into the accommodating opening 431. In the presence of the cloth, the clothes are clamped between the front detection piece 41 and the front end of the accommodating opening 431, and the front detection piece 41 is prevented from extending into the accommodating opening 431, so that the front detection piece 41 is not in contact with the rear detection piece 42, and the distance between the front detection piece 41 and the rear detection piece 42 is large. When no cloth clamping exists, the front detection piece 41 extends into the accommodating opening 431 and is in contact with the rear detection piece 42, and the distance between the reed pipe and the magnetic piece 412 is D1. The distance between the front end of the accommodating opening 431 and the front end of the rear detection piece 42 is D3; in the presence of the clamping cloth, the distance D2 between the reed pipe and the magnetic piece 412 is greater than D1 and less than or equal to the sum of D1 and D3.

For the cloth clamping detection, the cloth clamping detection device is arranged on a closing door body of the washing machine, and after the cloth clamping detection device is electrified, the detection device is started to carry out detection; if the fabric is clamped, the door body 20 is opened for checking. If the cloth is not clamped, the selection operation of the washing program is carried out.

In this embodiment, the first groove wall 1122 is inclined in the outward direction away from the center of the laundry inlet, which is advantageous in increasing the stability of the first groove wall 1122 after being assembled with the first assembling groove 31, and is advantageous in sealing the window gasket 30 between the window glass 13 and the first groove wall 1122 in accordance with the inclination direction of the window glass 13 of the door body 12 at the laundry inlet 111. Preferably, the included angle between the first groove wall 1121 and the rear groove wall 1122 of the first groove 112 is set to 40 ° to 50 °, and more preferably, the included angle between the first groove wall 1121 and the rear groove wall 1122 of the first groove 112 is set to 45 °.

The window gasket 30 has an extending edge 32 bent and extended downwards along the outer wall of the opening end of the first assembling groove 31, and the extending edge 32 is attached to the rear groove wall 1122 of the first groove 112, which is beneficial to increasing the sealing performance between the window gasket 30 and the first groove 112 and the firmness after assembling. Extending edge 32 is located on the front side of rear slot wall 1122.

The front plate 11 is provided with a backward second groove 113, and the inner side of the door body 12 is provided with a protrusion matched with the second groove 113, so that the door body 12 and the front plate 11 can be closed in a sealing manner. A laundry inlet 111 is opened at a rear wall of the second recess 113. An annular first groove 112 is arranged on the rear groove wall of the second groove 113, the first groove 112 and the second groove 113 are coaxially arranged, and the second groove 113 is coaxial with the clothes inlet 111. The second groove wall 1123 of the first groove 112 on the side away from the window pad 30 is parallel to the first groove wall 1121, which is advantageous for increasing the structural strength at the first groove 112 and for forming a larger space in which the detecting device 40 can be installed.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
