A drain cleaner apparatus for dispensing a cleaning composition into a condensate drain line of an air handler of an air conditioning system. The drain cleaner apparatus includes an apparatus reservoir configured to hold the cleaning composition, a connector interface configured to couple with the condensate drain line to cause an apparatus outlet of the drain cleaner apparatus to be in fluid communication with an opening of the condensate drain line, a dispenser device that is configured to be actuated to selectively dispense an amount of the cleaning composition from the apparatus reservoir and through the apparatus outlet, and a controller configured to actuate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention.

A purification structure is located beside an inlet segment of a heat dissipator and contains: a casing, a water mesh, a water distribution seat, and a water collection device. The casing includes an air inlet and an air outlet. The water mesh includes multiple orifices and is accommodated between the air inlet and the air outlet of the casing. The water distribution seat is secured on a top of the water mesh and includes an aperture and multiple passages. The water collection device communicates with a bottom of the water mesh, and the water collection device includes a water accommodation chamber and a pump, wherein the pump has a water output segment connecting with a guide tube which communicates with the aperture of the water distribution seat, such that the water is outputted by the pump to flow toward the aperture via the guide tube.

The present invention is directed to systems and methods for cleaning a component inside a machine, such as an evaporator coil inside an air conditioner. A pump is connected to a controlling device. The pump is also connected to a metering device. The metering device is connected to one or more reservoirs. The metering device is also connected to one or more wands. Each wand is positioned inside a housing containing the component to spray cleaning solution, drawn from the reservoirs by the metering device, onto a face of the component. To perform the cleaning of the component, the controlling device disables the machine. The controlling device then activates the pump. The pump causes cleaning solution to be drawn from the one or more reservoirs into the metering device, which then transfers the cleaning solution into the wands. The controlling device then allows the machine to resume operation.

The disclosed embodiments include systems and methods to clean ducts. In one embodiment, the method includes detecting airflow into an exhaust duct. The method also includes dosing, in response to detecting airflow into the exhaust duct, an amount of a treatment product with a fluid to produce a treatment fluid. The method also includes pumping the treatment fluid into a pipe deposited along the exhaust duct. The method also includes spraying the treatment fluid through a nozzle coupled to a section of the pipe to clean buildup formed along an area of the exhaust duct proximate to the nozzle.

A foot operated pump includes a water and airtight flexible and collapsible wall between a top plate and a base plate and an interior variable volume chamber. A flexible hose is selectively attachable to either an inlet port or an outlet port on the top plate member. The contents (air and/or liquid) within the variable volume chamber are forced out of the outlet port upon forced downward movement of the top plate member towards the base plate member. As the top plate member returns to a normally relaxed state in separated, angled relation to the base plate, the variable volume chamber enlarges and air is sucked through the inlet port to fill the variable volume chamber. An opposite end of the flexible hose attaches to various adapters and fittings for clearing clogged drain lines and other conduits.

A device including an outer hose segment, an inner hose segment, a first air chamber for accommodating a first air flow, a second air chamber for accommodating a second air flow, a drive tool coupler into engagement with a first end portion of the outer hose segment and inner hose segment, a cleaning end section that is configured to allow tools to be attached and detached to and from said device, and a hose coupler into engagement with a second end portion of the outer and inner hose segments, wherein the hose coupler is configured to control the first and second flow of air into the first and second air chambers independently.

Described herein relates to an apparatus and method for optimized dispensing of conduit cleaning agent(s). The apparatus may be configured to dispense cleaning agent(s) (e.g., vinegar and/or acetic acid) into a conduit line (e.g., a condensate drain) at predetermined timed intervals. The apparatus may be adapted for multi-unit dwellings where conduit pathways are shared between different units and air conditioning systems. The apparatus may include a plurality of timer-controlled valves (e.g., motorized valves), which may be synchronized to simultaneously release the cleaning agent(s). Additionally, the apparatus may comprise a reservoir that may gravity feed the cleaning agent(s) into these integrated timer/release valves. As such, activation by the timer may cause the release of the cleaning agent(s) into the conduit line via tubing. Accordingly, the system may be configured to prevent substance accumulation/occlusion in the conduit line of a HVAC, refrigeration, and/or septic system, and/or minimize the need for regular maintenance.

An apparatus configured to dispense a cleaner composition includes an apparatus outlet in fluid communication with an exterior of the apparatus, a dispenser device configured to be operated to selectively dispense an amount of the cleaning composition through the apparatus outlet, and a controller configured to operate the dispenser device to cause the amount of the cleaning composition to be dispensed through the apparatus outlet without manual intervention. The apparatus is configured to be electrically connected with a float switch concurrently with dispensing the cleaning composition, and the apparatus is configured to cause at least a portion of an air conditioning system to shut down in response to receiving a signal generated by the float switch.

A method for cleaning an air conditioner indoor unit and outdoor unit includes controlling a heat exchanger to enter a self-cleaning mode, adjusting an operating frequency of an air conditioner, an opening of a throttling device, and a corresponding fan speed of the heat exchanger, and maintaining an evaporating temperature of the heat exchanger within a present range to enable a frost process on a surface of the heat exchanger. When a differential pressure of the air conditioner meets a preset condition, a four-way valve changes a direction, switching defrosting to indoor and outdoor heat exchangers. When the differential pressure does not meet the preset condition, the air conditioner is adjusted to meet the preset condition and the four-way valve direction is changed to perform a defrosting switching to the indoor and outdoor heat exchangers.

An apparatus and method for cleaning split system air conditioning units. The apparatus comprises a shield functioning as a moisture barrier that sits between the wall and the AC unit and which releasably receives a drain pan that interconnects with the bottom of the shield to form a water tight seal. A flexible tube connects the bottom of the drain pan to a collection receptacle. Water and chemical sprayed into the unit to clean the unit drain through the unit, into the drain pan, through the tubing, and are collected by and can be disposed of from the receptacle. After the AC unit is cleaned, the drain pan, tubing and collection receptacle are removed leaving the area clean and dry. Kits comprising the apparatus of the invention can be sold together with new AC units or purchased separately.
