A washout system for a concrete mixer vehicle includes a plurality of valves, a plurality of nozzles, and a controller. The plurality of valves are configured to (i) be fluidly coupled to a pump and a fluid tank and (ii) receive a fluid from the pump. One or more of the plurality of nozzles are fluidly coupled to a respective one of the plurality of valves. Each of the plurality of nozzles are configured to provide the fluid to a respective target when the respective one of the plurality of valves is selectively activated to an open position. The controller is configured to monitor a plurality of washout parameters during operation of the concrete mixer vehicle and initiate one of a plurality of washout modes in response to a subset of the plurality of washout parameters being satisfied for the one of the plurality of washout modes.

Spray head assemblies, including an air-handling saddle that is attachable to a liquid spray gun platform, a liquid-handling core that is slidably engagable into the air-handling saddle, and an air cap; spray guns using such assemblies; and, methods of using such assemblies.

A de-ice apparatus is configured to remove ice buildup in containers or other locations by melting the ice using a de-ice component and to remove waste fluid using a vacuum component. The de-ice component causes discharge of pressurized fluid to melt ice. The de-ice component may include a base with guide features configured to engage an opening of the container. The de-ice component may direct a spray of the pressurized fluid into the container to melt the ice. The de-ice component may include a pressure regulator valve to selectively regulate a resulting force of the fluid sprayed into the container, which may enable a user to avoid damaging internal components located within the container. The vacuum component may cause the pressurized fluid to flow through a high pressure nozzle to create a vacuum effect at a suction inlet, which can extract waste fluid and/or other debris from the container.

An apparatus is disclosed that is designed to be able to clean HVAC condensers. The apparatus comprises a plurality of pipes that facilitates the passage of water through them allowing water and/or a cleaning solution to clean the condenser by spraying the condenser with sprayers without having to move the apparatus. The apparatus is designed so as to be able to spray every part of the condenser without having to move the apparatus. The apparatus may also have a timer associated with it that allows the condenser to be cleaned at periodic intervals.

A substrate treatment method is performed by a substrate treatment apparatus including a substrate holding unit which holds a substrate, and a hot plate which heats the substrate from below. The method includes: a treatment liquid supplying step of locating the hot plate at a retracted position at which the hot plate is retracted below the substrate holding unit and, in this state, supplying a treatment liquid to an upper surface of the substrate held by the substrate holding unit; a protection liquid film forming step of forming a liquid film of a protection liquid to cover an upper surface of the hot plate in the treatment liquid supplying step; and a substrate heating step of heating the substrate by the hot plate with the hot plate being located adjacent to a lower surface of the substrate or in contact with the lower surface of the substrate.

In-wall dispensing modules, such as room freshener modules, can reside in a housing with a cover that can be opened to access an interior space of the module to, inter alia, replace used containers. The housings are configured to reside inside a wall of a room. The front cover can be a planar cover that is flush, slightly recessed or slightly protrudes from the wall. The housings can be a “custom” housing size and/or may be configured to occupy a single gang box or a compartment of a multi-gang junction box. The modules can include an actuator that can cause a canister to emit scented fluid at desired intervals and/or on-demand. The modules can have a User Interface (UI) wireless and/or wired connection to a whole-house “smart” system.

A shower assembly includes an inlet port, a reservoir, and a plurality of drop outlet ports. The inlet port is configured to receive a flow of water from a water source. The reservoir is configured to receive the flow of water from the inlet port. Each drop outlet port of the plurality of drop outlet ports includes an inlet, an outlet, and a bore extending therebetween. The shower assembly is configured such that, even when the reservoir receives the flow of water at a maximum inlet flow rate, the drop outlet ports only produce discrete water drops. A first plurality of the drop outlet ports is configured to produce only discrete water drops having a first size and a second plurality of the drop outlet ports is configured to produce only discrete water drops having a second size that is greater than the first size.

Disclosed is a two-in-one cleaning apparatus. The two-in-one cleaning apparatus includes a positioning assembly, a booster pump, an automatic hose reel, an intermediate connecting rod, and a spray gun body. The booster pump, the automatic hose reel, the intermediate connecting rod, and the spray gun body are all detachably mounted on the positioning assembly. The booster pump is provided with a water inlet and a water outlet, a water inlet pipe is arranged at the water inlet of the booster pump, and the water outlet of the booster pump is connected to the automatic hose reel. The automatic hose reel is provided with a mounting bracket, the positioning assembly is provided with a positioning support plate matching the mounting bracket, and the automatic hose reel is mounted on the positioning assembly through matching between the mounting bracket and the positioning support plate. The spray gun body is detachably connected to the booster pump and the intermediate connecting rod, respectively. The disclosure has the beneficial effects of being convenient to carry, high in stability, wide in application range, capable of meeting different use requirements, convenient to dismount and mount, simple in structure and convenient to operate.
