An inline shower device includes a housing, a hydraulic chamber, a first actuator, and a fluid-driven piston. The housing includes an outlet port. The hydraulic chamber is disposed within the housing. The first actuator is configured to connect a capsule to the housing and to fluidly connect the capsule to the hydraulic chamber. The fluid-driven piston is disposed within the hydraulic chamber and is configured to dispense a fluid from the capsule into the outlet port.

In a method for carrying out a cleaning procedure for a cooking appliance, a first tank of the cooking appliance is filled by a user with water. A first portion of water in the first tank is moved into a buffer store and then moved from the buffer store into a cooking chamber to provide a first treatment agent therein. The first treatment agent remains in the cooking chamber for a first time period. A second portion of water in the first tank is moved into the buffer store and the first treatment agent is moved into the first tank. The second portion of water in the buffer store is into the cooking chamber to provide a second treatment agent in the cooking chamber. The second treatment agent remains in the cooking chamber for a second time period and the second treatment agent is then moved into the first tank.

By injecting a chemical fluid and a carrier fluid directly at each nozzle, and by then mixing the fluids at each nozzle to produce a mixed fluid, an improved spray system may be provided which does not contaminate the tank or distribution system with chemical fluid and which allows improved spraying with minimal delay. Accordingly, a system is provided on a field sprayer for independently controlling the flow rate of concentrated chemical fluid to individual spray nozzles using a high pressure chemical distribution rail or loop routed to each nozzle and solenoid injection valves to control the flow of chemical fluid to each nozzle independently.

A system for metering liquids at very low flows for use with agricultural sprayers is provided. The system may utilize two electronically controlled solenoid valves in series with a storage chamber in between. The flow may be a function of the PWM control of each of the valves, the phase relationship between the control signals, the storage chamber in between, the pressure difference across the metering device, and the fluid being metered.

With the use of a low cost microphone mounted at each nozzle, a sound signature of the nozzles may be captured and stored to be used as a continuous indicator of any changes in the flow rate of the nozzles. By measuring changes in sound at each nozzle, it is possible to determine the change in flow before a change in pressure manifests into a problem in the system. The change in sound will oftentimes be significant for plugged nozzles, or nozzles that have excessive wear and flow at too high of a rate. The invention has the advantage of being relatively low cost with ceramic microphones, for example, and with little or no moving parts required. A closed loop control system may be included to compensate for nozzle degradation.

A method for detecting at least one spray liquid data set of a spray liquid applied to an agricultural area using at least one spray nozzle unit of a spraying device. The method includes receiving a property signal, including a piece of property information of the spray liquid detected using a sensor unit of the spraying device in a through-flow area of the spray nozzle unit during an application operation of the spray liquid; receiving a position signal, including a piece of position information of the spray liquid, using a position unit, the position information representing a geographic position of the spray liquid during the application operation of the spray liquid; and storing the property information and/or a piece of spray liquid information of the applied spray liquid ascertained using the property information, together with the associated position information, using an information unit, for detecting the spray liquid data set.
