A drain pump for a laundry treating apparatus includes a housing, an impeller, a motor, a circulation outlet, and a drain outlet. The circulation outlet and the drain outlet are defined on an outer circumferential surface of the housing, enable communication of the washing water with the housing, and protrude outward in directions tangential to the outer circumferential surface. The housing includes a rib that protrudes from an inner circumferential surface of the housing, that is located between the circulation outlet and the drain outlet, and that is to configured to guide the washing water to the circulation outlet or to the drain outlet based on a direction of rotation of the impeller.

Disclosed is a washing machine including: a gasket, wherein the gasket includes a plurality of nozzles provided on an inner circumferential surface of a gasket body to spray water into a drum, and a plurality of port receiving pipes protruding from an outer circumferential surface of the gasket body and respectively communicating with the plurality of nozzles; a distribution pipe supplying water pumped by a pump to the plurality of nozzles; and a first balancer disposed at a front surface of a tub. At least a portion of the first balancer is spaced apart from the outer circumferential surface of the gasket body, and at least a portion of a transport conduit of the distribution pipe is disposed in a space between the first balancer and the gasket body, and accordingly, separation of the distribution pipe from the gasket is prevented.

A heat pump module for a laundry treatment device and the laundry treatment device are provided. The heat pump module includes a base plate, a top cover and a compressor. The base plate has a first side wall and a second side wall adjacent to the first side wall; the top cover defines a mounting chamber together with the base plate; the compressor is located in the mounting chamber; and an extension line of an axis of the compressor intersects with the first side wall and the second side wall separately. For the heat pump module according to the present invention, the extension line of the axis of the compressor intersects with the first side wall and the second side wall, which facilitates the layout of leads and pipes connected with the compressor and the arrangement of other components on the base plate, thereby improving utilization rate of installation space on the base plate and optimizing the layout scheme of the heat pump module.

A control method of a laundry treatment apparatus is disclosed. The control method includes rotating the drum at a predetermined first number of rotations to measure the weight of the laundry stored in the drum (a laundry weight measurement step), rotating the drum at a predetermined second number of rotations to determine the magnitude of the dynamic unbalance of the drum (an unbalance measurement step), accelerating the drum to a target number of rotations, which is greater than the first number of rotations and the second number of rotations, when the magnitude of the dynamic unbalance measured at the unbalance measurement step is less than a predetermined reference value (an acceleration step), interrupting the rotation of the drum when the variation per unit time of current supplied to the stator during execution of the acceleration step is equal to or greater than a predetermined reference variation (a first interruption step), rotating the drum at the first number of rotations to determine the weight of the laundry stored in the drum (a laundry weight remeasurement step), and interrupting the rotation of the drum when the deviation between the laundry weight measured at the laundry weight remeasurement step and the laundry weight measured at the laundry weight measurement step is equal to or greater than a predetermined reference deviation (a second interruption step).
