Finally described are a method and a device for the production of a cleaning and/or rinsing agent molded article (1, 1, 1) of this type.

An oven includes chamber with a food drippings drain path along which food drippings can flow for removal from the chamber. A steam input arrangement associated with the chamber includes a separate exit flow path for excess water.

A multi-compartment oven provides in-place cleaning through the use of distributed spray nozzles possibly augmented by steam, fan blowing, and heat from other components of the oven. A centralized draining system allows recycling of the water without breaching the separation between the cooking compartments.

An aircraft oven includes a first portion having an inner cavity surrounded by an inner housing. The first portion includes a ventilation area. The aircraft oven also includes a second portion including a water line that extends through the second portion, and wherein the water line extends along the inner housing, a first plurality of nozzles configured to extend from the water line into the inner cavity, and a second plurality of nozzles configured to extend from the water line, through the inner housing and into the ventilation area.

There is provided a cooker including: a cooking room; a steam generator configured to generate steam, and to supply the steam to the cooking room; a water level sensor configured to sense a water level of a cleaning solution stored in the inside of the steam generator; a supply apparatus including a storage unit configured to accommodate the cleaning solution, a supply pump configured to supply the cleaning solution accommodated in the storage unit to the steam generator, and a drain pump configured to supply the cleaning solution remaining in the steam generator to the storage unit; and a controller configured to control operations of the supply pump and the drain pump, wherein the controller operates the supply pump in a washing mode, operates the drain pump when the cleaning solution is fully filled in the steam generator, and again operates the supply pump when the cleaning solution is removed from the steam generator.

A system 1 comprises a self-cleaning rotisserie oven 2 with a casing 4, a door 6, and an oven cavity 8, for cooking a food product. The system 1 further comprises a cleaning unit 10, which is a separate unit from the self-cleaning oven 2. The cleaning unit 10 comprises a frame 12, supporting a water tank 14, and a waste water tank 16. The frame 12 of the cleaning unit 10 is movably supported by wheels 18. The cleaning unit 10 comprises a push bar 20. The self-cleaning rotisserie oven 2 comprises a discharge hose connector 22, and a water hose connector 24, for connecting a discharge hose 26, and a water hose 28 respectively, to the cleaning unit 10. The self-cleaning rotisserie oven 2 further comprises a control 30 with a user interface, and a timer. The system 1 also comprises a second self-cleaning rotisserie oven 32.

A Cooking oven (100) comprising a) at least one cooking cavity (102) and b) at least one steam generation system (40) for introducing steam into the cooking cavity (102) during a steam operating mode, in particular steam cooking mode or steam cleaning mode, c) wherein the steam generation system (40) comprises c1) at least one steam generator (42), c2) at least one fluid supply (44), the fluid preferably being water with impurities, in particular calcium, and optionally additives and c3) at least one valve (2), d) wherein the valve (2) is interconnected between the fluid supply (44) and the steam generator (42) in order to control the flow of fluid from the fluid supply (44) to the steam generator (42) during the steam operating mode, e) wherein the valve (2) comprises at least one inlet (12) for the fluid being in fluid connection with the fluid supply (44) f) wherein the valve is in fluid connection with the steam generator (42) by means of at least one connecting line (50), g) wherein the valve (2) is provided with at least one closing device (19) for closing and opening the inlet (12) of the valve at least partially during the steam operating mode in order to keep the fluid level within the valve at an operating level within an operating level range during the steam operating mode, h) the cooking oven further comprising one or more of the following features: h1) the valve (2) and the steam generator (42) and the connecting line (50) are arranged in such a way that the level of the fluid within the steam generator (42) and within the valve (2) is kept the same during the steam operating mode and/or wherein the valve (2) and the steam generator (42) and the connecting line (50) are arranged according to the principle of communicating vessels, h2) the operating level (N) or the operating level range during the steam operating mode is, in the direction of gravity, higher than or at the same level as the inlet (12) of the valve (2).

A drain control system receives a first indicator of start of a cleaning cycle. In response to receipt of the first indicator, a signal is sent to turn on a drain pump mounted within a drain tank to evacuate a fluid stored in the drain tank when the drain tank is not indicated as empty. A second indicator is received that a cleaning fluid has been provided to a storage tank. After the drain tank is indicated as empty, circulation of the cleaning fluid is controlled within a drain system. The drain system drains the cleaning fluid into the drain tank after circulating within the drain system. The drain pump is controlled to turn on to evacuate the cleaning fluid from the drain tank based on a fluid level indicator generated by a fluid level sensor after the cleaning fluid drains into the drain tank.
