A warewash machine arm mechanism includes a liquid supply shaft assembly including a rotatable sleeve bearing mounted thereon, and an arm assembly including an elongated interior liquid flow space along an arm body and one or more liquid ejection orifices. The arm assembly is releasably mounted to the supply shaft assembly via a latch mechanism of the arm assembly that engages the rotatable sleeve bearing such that the arm assembly rotates with the rotatable sleeve bearing during ejection of liquid from the liquid ejection orifices.

A flow through chemical sensor includes a housing having a through passage along which chemical can flow, a sidewall of the housing having first and second openings that communicate with the through passage. A first electrode is mounted on the housing and aligned with the first opening, the first electrode of a plate configuration with a unitary depression that extends through the first opening and to a peripheral edge of the through passage. A second electrode is mounted on the housing and aligned with the second opening, the second electrode of a plate configuration with a unitary depression that extends through the second opening and to the peripheral edge of the through passage. A method of detecting presence or absence of chemical is also provided.

Warewash machine chemical sensor and related system and method

A warewasher for washing wares includes a chamber for receiving wares. The chamber has an associated liquid delivery system for spraying liquid onto wares within the chamber. A tank collects the sprayed liquid. A liquid recirculation system moves liquid from the tank back to the liquid delivery system. A drain system is located within the tank. The drain system includes a well, a liquid recirculation system inlet within the well and a drain opening within the well. A drain control assembly includes a drain stopper member and a strainer connected with the drain stopper member. When the drain stopper member is positioned to block flow through the drain opening, the strainer is positioned to block passage of tableware into the well. The strainer is mounted for sliding movement along a length of the drain stopper member enabling, when the drain stopper member is raised slightly to permit flow out of the drain opening, the strainer to remain in position to block passage of tableware into the well.

A warewash machine includes a housing including an area for receiving wares to be washed and a liquid dispensing arm removably positioned within the housing, the liquid dispensing arm including a nozzle receiving opening. Removably positioned in the nozzle opening is a nozzle that is configured to output liquid in a specific output pattern. The nozzle receiving opening and the nozzle are cooperatively shaped and configured such that when the nozzle is inserted in the nozzle receiving opening the nozzle is automatically positioned such that an orientation of the specific output pattern relative to the area is automatically set to a specific orientation.

A warewasher jam detection system includes a conveyor drive arrangement having a drive motor assembly including a drive motor and an output shaft, and a slip clutch including an input side moved via the output shaft and an output side operatively connected for driving a conveyor. At least one sensor is provided for producing an output indicative of movement/non-movement of the output side of the clutch. Preferably the sensor is a non-contact type sensor such as a magnetic sensor, optical sensor or proximity sensor. A controller may be provided for receiving the sensor output signals and identifying a jam condition based upon the same, such that the controller can responsively stop the drive motor.

A longitudinal warewasher section, of a warewasher assembly having a plurality of warewasher sections mounted end-to-end, includes a frame and a control box pivotally mounted thereto, where the control box is pivotable from a compact, shipping orientation to an installation or operating orientation. The control box preferably includes electrical controls that have been pre-wired to the electrical and/or mechanical components of the warewasher section. When in the shipping position, the rear face of the control box lies substantially flush against a lateral end of the frame and the side face of the control box is substantially flush with the longitudinal front wall of the frame such that the control box faces outwardly from the lateral end of the frame. In this orientation, the control box does not add to the total lateral width of the warewasher section. After the warewasher section has been shipped and unloaded, the control box is pivoted substantially 90&deg; about hinges to an operating orientation, in which the rear face of the control box is perpendicular to the lateral end of the frame and the control box faces outwardly from the longitudinal front side of the frame. Once the control box is pivoted to this orientation, the end-to-end connection of the remaining warewasher sections to the present section may then continue.

Method for assembling a warewasher assembly

A drain valve for controlling the flow of water from a source of standing water to a drain, the drain valve comprising: a valve body, an inlet in said valve body connectable to said source, an outlet in said valve body connectable to a drain, a fluid passageway through said valve body running from said inlet to said outlet, a cavity in said valve body intersecting said passageway, a gate disposed in said cavity, said gate being movable between an open position wherein water can flow through said passageway to a closed position wherein the flow of water through said passageway is blocked, a water supply line for supplying water under pressure to said cavity on one side of said gate, and a water supply valve for controlling the flow of water from said supply line to said cavity, whereby when said water supply valve is open, water flows into said cavity and moves said gate from said open position to said closed position and when said water supply valve is closed, said gate returns to said open position.
