Electrical power supply cord retention systems are described. Also described are drain cleaning machines using such cord retention systems. In addition, methods of selectively retaining power cords in association with drain cleaning machines are described.

Automated unblocking device for plumbing trap for sinks, wash basins or similar, arranged in an installation with a plumbing trap, a pipe, a siphon, a connecting piece, connected to a valve of the basin that is located between the valve of the basin and the siphon and has a receptacle consisting of a compartment of products, a discharge medium compartment and an electronic compartment for control and command, where the mediums for the air freshener functions are housed, including an air freshener discharge pump, an air freshener compressor and a nebuliser as well as an unblocking compartment having a unblocker discharge pump, an unblocking tank with a nozzle for expelling the unblocker to the water supply pipe.

The present disclosure relates to a drain pump driving apparatus and a laundry treatment machine including the same. A drain pump driving apparatus according to an embodiment of the present disclosure and a laundry treatment machine including the same include: an inverter converting a direct current (DC) voltage from a converter into an alternating current (AC) voltage based on a switching operation and to output the converted AC voltage to a drain motor; and a controller to control the motor to, when a drain channel in a drain pump is clogged, be temporarily stopped in a period during which a speed of the motor increases and then to repeatedly rotate and stop in a first direction the same as a start-up direction, and to repeatedly rotate and stop in a second direction opposite to the first direction when the drain channel is clogged even after the motor repeatedly rotates and stops in the first direction. Accordingly, when impurities are introduced into the drain pump, the impurities can be removed in a simple manner.

A tool for removing articles from a drain includes a rod that has a first end, a second end and a peripheral surface extending between the first and second ends. A hook is attached to and extends away from the first end of the rod. A magnet is attached to the second end of the rod.

The present invention is an pipe cleaning device which can be inserted into a drain pipe and coupled to the sink drain by removing the trap. The device includes an access port and a deflector tube coaxially held within a tee coupling attaching to the drain pipe providing a restriction creating turbulence and a surge of fluid in order to remove scum and algae build up which accumulates on the upper surface of a drain pipe above the water level.

The drain-unclogging straw is a chemical device. The drain-unclogging straw comprises a drain clearing device and a domestic DWV system. The domestic DWV system further comprises a drain. The drain contains biochemically-generated material that inhibits the flow of wastewater through the drain. The drain clearing device is a chemical device that is formed as a kit. The drain clearing device breaks the biochemically-generated material down into components that will flow through the drain. The drain clearing device comprises a straw and a chemical compound. The chemical compound is in a solid phase. The straw contains the chemical compound. The straw is placed directly in the drain. Once in the drain, the straw dissolves such that the chemical compound is released into the drain. The chemical compound chemically interacts with the biochemically-generated material such that the biochemically-generated material is broken down.
