Abstract: A detergent dispensing apparatus 3 used for a dish washer and a dish washer comprising the detergent dispensing apparatus 3. The detergent dispensing apparatus 3 comprises a liquid storage box, a liquid outlet pump 32 and a pipeline module. The liquid storage box comprises a first half housing and a second half housing, and the first half housing and the second half housing fixedly connect each other in a first direction so as to define a liquid storage cavity used for storing detergent. The liquid outlet pump 32 is configured to suction the detergent from the liquid storage cavity and dispense the detergent to the exterior of the detergent dispensing apparatus 3. The pipeline module comprises a liquid adding channel used for adding the detergent to the liquid storage cavity, a liquid inlet channel used by the liquid outlet pump 32 for extracting the detergent from the liquid storage cavity, and a liquid outlet channel used by the liquid outlet pump 32 for dispensing the detergent.

Abstract: A motor device is provided. The motor device includes a motor, a lead screw, a transmission mechanism and a housing. The transmission mechanism is configured to transmit rotation of the motor to the lead screw. The housing includes a housing outer wall to define a housing cavity and a partition to define a transmission cavity for accommodating the transmission mechanism. The transmission cavity is inside the housing cavity. The housing cavity also accommodates at least a portion of the lead screw. The partition includes a first protruding sidewall and a second protruding sidewall respectively on either side of the transmission cavity, and the transmission cavity is sealed for a lubricant that is used for the transmission mechanism and contained in the transmission cavity.
