Device for monitoring a wash process
View Patent ↗A device is provided for monitoring a wash process inside a mechanical washing apparatus, comprising sensor means for measuring physical and/or mechanical parameters of the wash process and recording means for recording the measured parameters within the device. This device comprises means for conducting a washing liquor past the sensor means and means for determining a certain contact time between the washing liquor and the sensor means.
1. A device for monitoring a wash process inside a mechanical ware washing apparatus, the device comprising:
a housing that can be received within a washing chamber of the ware washing apparatus during a wash cycle, the housing configured to conduct washing fluid through a flow path having a shape that is similar to a bottle, the flow path having an entry positioned at a mouth of the bottle shape, an exit positioned at a base of the bottle shape, the exit having a cross-section that is smaller than the cross-section of the entry to control the flow rate of washing fluid through the flow path;
a sensor coupled to the housing and positioned within the flow path to measure physical and/or mechanical parameters within a bottle being washed by the ware wash apparatus; and
a recording device coupled to the housing and in communication with the sensor to record measured parameters.
2. A device according to claim 1 , wherein the sensor is located in a central cavity of the device and wherein an entry connects the surroundings with the central cavity.
3. A device according to claim 2 , wherein the entry extends substantially centrally of the device, whereas the exit comprises a circumferential slot extending radially outward from the central cavity.
4. A device according to claim 1 , wherein the entry is provided with an entry funnel.
5. A device according to claim 1 , wherein the entry is covered by a filter.
6. A device according to claim 1 , wherein an obstruction means is provided at the exit.
7. A device according to claim 1 , further comprising an attachment means for attaching the device to the mechanical washing apparatus.
8. A device for monitoring a wash process inside a mechanical laundry washing apparatus, the device comprising:
a housing that can be received within a washing chamber of the laundry washing apparatus during a wash cycle, the housing configured to conduct washing fluid through a flow path having an entry, an exit, and a meandering flow path between the entry and the exit, the exit having a cross-section that is smaller than the cross-section of the entry to control the flow rate of washing fluid through the flow path;
a sensor coupled to the housing and positioned within the flow path to measure physical and/or mechanical parameters within the laundry wash apparatus; and
a recording device coupled to the housing and in communication with the sensor to record measured parameters.
9. A device according to claim 8 , wherein the sensor is located in a central cavity of the device and wherein an entry connects the surroundings with the central cavity.
10. A device according to claim 9 , wherein the entry extends substantially centrally of the device, whereas the exit comprises a circumferential slot extending radially outward from the central cavity.
11. A device according to claim 10 , wherein the central cavity is surrounded by a ledge partially separating the central cavity from the exit channel.
12. A device according to claim 8 , wherein the entry is provided with an entry funnel.
13. A device according to claim 8 , wherein the entry is covered by a filter.
14. A device according to claim 8 , wherein an obstruction means is provided at the exit.
