The washing machine is a pulsator washing machine or a drum washing machine, a detergent box accommodating cavity is formed in the washing machine, a detergent box is arranged in the detergent box accommodating cavity, and the detergent box is connected with a water inlet of the washing machine. A user puts liquid or solid detergent into a detergent box, after a washing program is started, water flows out of a water inlet pipe and enters the detergent box, and the detergent in the detergent box enters an inner barrel of the washing machine under the washing of water flow. When the detergent box is not installed in place, the detergent can not completely enter the inner barrel, even when the detergent box is separated from the washing machine under the condition that a user does not know, water flow can flow out along the containing cavity of the detergent box during washing or rinsing water injection, therefore, the first sensing device is arranged on the containing cavity of the detergent box or the detergent box, and whether the detergent box is installed in place or not is judged through the first sensing device.

Furthermore, one end of the detergent box accommodating cavity is opened, the detergent box is inserted into the detergent box accommodating cavity from the opening, and the first sensing device is arranged at one end of the detergent box accommodating cavity far away from the opening, or the first sensing device is arranged at one end of the detergent box inserting opening; when the first sensing device is arranged at one end of the accommodating chamber far away from the opening, the insertion end of the detergent box is inserted into the bottom of the detergent accommodating chamber and is installed in place, and then the first sensing device is contacted with the insertion end of the detergent box, so that a communication signal is sent. When the first sensing device is arranged at the insertion end of the detergent box, the insertion end of the detergent box is inserted into the bottom of the detergent containing chamber and is installed in place, and then the first sensing device is contacted with one end, far away from the opening, of the containing chamber, so that a communication signal is sent out. In order to make the detection result more accurate, it is preferable that the first sensing device is a contact switch, the contact switch is connected to the first circuit, and when the detergent box is mounted in place, the contact switch connects the first circuit.

Furthermore, when the washing machine is in the dewatering process, the detergent box is not installed in place, the loosened detergent box collides with the washing machine under the condition of high-speed dewatering of the washing machine, so that high noise is generated, and even the detergent box is separated from the washing machine in the high-speed dewatering process, so that the detergent box is damaged. Therefore, in order to avoid the loss caused by the improper installation of the detergent box in the dehydration process, the second sensing device is arranged in the accommodating cavity of the detergent box, and whether the detergent box is separated from the washing machine or not is judged by the second sensing device; in order to make the detection result more accurate, it is preferable to arrange the second sensing device at the opening end of the detergent box accommodating cavity, so that the second sensing switch is communicated no matter the detergent dispenser box is pulled outwards or pushed inwards, thereby indicating that the detergent box is not completely taken out. When the detergent box is separated from the washing machine, the opening end of the detergent containing cavity can not sense the switch-on signal, and then the detergent box is judged to be separated from the washing machine.

More preferably, the second sensing device is a push switch, the push switch is connected to the second circuit, the push switch maintains a connected state when the detergent box is in the detergent box accommodating chamber, and the push switch disconnects the second circuit when the detergent box is detached from the washing machine.

The washing machine further comprises a controller, wherein the controller is connected with the first sensing device and the second sensing device, and the controller controls the operation of the washing machine according to the on-off conditions of the first sensing device and the second sensing device.

In order to prevent water from flowing out along the detergent box accommodating cavity due to the fact that the detergent box cannot be installed in place, potential safety hazards and inconvenience are brought to a user, before washing water or rinsing water enters the washing machine, whether the first sensing device is communicated or not needs to be judged in advance, if the first sensing device is communicated, the detergent box is installed in place is judged, the washing machine carries out washing or rinsing according to preset parameters, if the first sensing device is disconnected, the detergent box is judged not to be installed in place, in order to avoid water flow from flowing out of the detergent box accommodating cavity, the washing machine is paused at the moment, after the detergent box is installed in place by the user, the washing machine resumes operation, and washing or rinsing is carried out according to the preset parameters.

Further, in order to prevent the problem that the detergent box is not installed in place and collides with the washing machine during the dewatering process to generate noise, a second sensing device is further arranged on the detergent box and used for detecting whether the detergent box is separated from the washing machine or not. Before the dewatering program begins or in the dewatering process, whether the first inductive switch is connected or not is detected at any time, if the first inductive switch is detected to be in a connected state, then the detergent box is judged to be installed in place, the washing machine operates according to preset dehydration parameters, if the first inductive switch is detected to be disconnected, further detecting whether the second inductive switch is connected, if the second inductive switch is connected, judging that the detergent box is not installed in place but is not separated from the detergent box accommodating cavity, and dehydrating after the washing machine readjusts the dehydration rotating speed, if the preset dehydration rotating speed is 800rpm, the dehydration rotating speed is reduced to 400rpm, the specific dehydration rotating speed is set to be obtained through a large amount of test data, therefore, the detergent distributor box is prevented from being not completely installed in place, abnormal vibration is generated during high-speed dehydration, and the structure of the washing machine is prevented from being damaged. If the second detection device is in a disconnected state, the detergent box is judged to be separated from the washing machine, the program operation is suspended, and the alarm device is started to prompt a user that the detergent box is separated from the washing machine.

Further, the washing machine further comprises an alarm device, and when the first sensing device or the second sensing device is disconnected, the alarm device is started to remind a user of installing the detergent box in place.
