Problems solved by technology

In the above solution, the water quality sensor is set in the outer tub, and it starts to work only when the set water level reaches the preset water level and the inner tub starts to rotate. The detection is not timely, and at the same time, the washing machine starts to detect again, and stops running when there is no detergent. The process is ineffective washing, which consumes water and electricity. At the same time, the water quality sensor is located in the outer tub and is soaked in the detergent solution throughout the washing process, which reduces the service life of the sensor.

Embodiment 1

[0031] The invention provides a detergent box, such as figure 1 and figure 2 As mentioned above, it includes a box body 1, a drawer 2 and a controller. The bottom surface of the box body 1 is provided with a water outlet 3, and the front end of the box body 1 is provided with an opening, and the rear end of the drawer 2 is inserted into the box body 1 through the opening. The front end of 2 is provided with a drawer handle 21, and the drawer handle 21 is exposed outside the box body 1. The drawer 2 is provided with a manual feeding cavity 22 and an automatic feeding chamber 24. The drawer 2 is also provided with an upper dissolving channel, and the box body 1 is also provided with a The lower dissolving channel, the manual feeding chamber 22, the upper dissolving channel, the lower dissolving channel and the water outlet 3 are connected in sequence, and the detergent box is provided with a detection electrode 5 for detecting whether there is detergent and dissolved. The dete...

Embodiment 2

[0043] This embodiment provides a detergent box. The detection electrode 5 is arranged on the drawer 2. Specifically, the detection electrode 5 is fixedly connected to the bottom surface of the drawer 2. The box body 1 is provided with a conductive piece connected to the controller. When the drawer 2 is inserted into the When the box body 1 is in place, the detection electrode 5 is connected to the conductive member. The detection electrode 5 includes a pair of oppositely arranged positive electrode pieces 51 and negative electrode pieces 52. The positive electrode pieces 51 and the negative electrode pieces 52 pass through the bottom surface of the drawer 1 and extend into the communication opening 23. A gap 53 is provided between the positive electrode sheet 51 and the negative electrode sheet 52 for the liquid at the communication port 23 to flow through. The detection electrode 5 is connected to the conductive part, and the controller can monitor whether there is detergent ...

Embodiment 3

[0049] This embodiment provides a washing machine, which includes an inner tub and an outer tub, and further includes the detergent box of any one of the above embodiments, where the detergent box is located above the outer tub and communicates with the outer tub through a water outlet. By detecting the output voltage of the liquid in the detergent box through the detection electrode 5, it is accurately determined whether the detergent is put in and whether it is dissolved, so that the automatic feeding system can be started in time, and the intelligence of the whole washing machine is further improved.

[0050] Refer to Embodiment 1 for other undescribed structures.

Abstract

The invention discloses a detergent case which belongs to the field of household electrical appliance fittings, solving the problem of repeated release of detergent in an automatic release chamber anda manual release chamber; The technical scheme for solving the problem comprises a case body and a drawer; the drawer is inserted in the case body; the case body is provided with a water outlet; thedrawer is provided with the manual release chamber and the automatic release chamber; the drawer is provided with an upper dissolving channel; the case body is provided with a lower dissolving channel; the manual release chamber, the upper dissolving channel, the lower dissolving channel and the water outlet are successively connected; the detergent case is provided with a detecting electrode fordetecting whether there is detergent and whether the detergent is dissolved. The invention also provides a washing machine with the above detergent case and a method for controlling the detergent release. By means of the invention, whether there is detergent in the manual release chamber can be detected and whether the detergent is dissolved can also be detected.

Description

technical field [0001] The invention relates to household appliance accessories and household appliances, in particular to a detergent box and a washing machine with the detergent box, and also relates to a detergent feeding control method. Background technique [0002] For washing machines with an automatic dosing system, the detergent box includes an automatic dosing chamber and a manual dosing chamber. Regardless of whether the manual dosing chamber is filled with detergent, the automatic dosing system will start, and the detergent in the automatic dosing chamber will be put into the outer tub. , when detergent has been put into the manual feeding chamber, it will cause waste of repeated feeding of detergent. At the same time, the detergent will agglomerate or deteriorate when stored in the automatic feeding chamber for a long time. The detergent cannot be dissolved during automatic feeding, and its washing effect cannot be achieved. expected. [0003] In order to solve ...
