Abstract

An automated cleaning machine may include one or more short cleaning cycles in which the duration of a cleaning cycle is shortened relative to the duration of a default cleaning cycle. During a short cleaning cycle, other cleaning cycle parameters may also be adjusted to ensure that the articles subjected to the short cleaning cycle are adequately cleaned and sanitized. For example, the wash temperature, rinse temperature, and/or cleaning product amounts or concentrations, may be adjusted to account for the shortened duration of the cleaning cycle. The automated cleaning machine may further include one or more short cycle mode(s) during which short cleaning cycle parameters are used and one or more default cycle mode(s) during which default cleaning cycle parameters are used.

First claim

The invention claimed is:

1. An automated cleaning machine comprising:
a wash chamber configured to receive one or more articles to be cleaned, wherein the one or more articles are not component parts of the automated cleaning machine and are configured to be inserted and removed from the automated cleaning machine;
a controller comprising:
at least one processor; and
at least one storage device that stores one or more default cleaning cycle parameters associated with a default cycle mode and one or more short cleaning cycles parameters associated with a short cycle mode,
the at least one storage device further comprising instructions executable by the at least one processor to:
execute a first set of consecutive cleaning cycles using the one or more default cleaning cycle parameters to wash one or more first sets of the one or more articles;
determine first time durations between at least a first predetermined number of cleaning cycles in the first set of consecutive cleaning cycles;
determine that the first time durations satisfy a short cycle threshold;
in response to determining that the first time durations satisfy the short cycle threshold, execute at least one first subsequent cleaning cycle using the one or more short cleaning cycle parameters to wash a second set of the one or more articles;
execute a second set of consecutive cleaning cycles using the one or more short cleaning cycle parameters, wherein the second set of consecutive cleaning cycles includes a second predetermined number of cleaning cycles, wherein the second set of consecutive cleaning cycles includes the at least one first subsequent cleaning cycle, and wherein the cleaning cycles of the second set of consecutive cleaning cycles have shorter total cycle durations than the cleaning cycles of the first set of consecutive cleaning cycles;
determine second time durations, the second time durations being between cleaning cycles in the second set of consecutive cleaning cycles;
determine that the second time durations do not satisfy the short cycle threshold; and
in response to determining that the second time durations do not satisfy the short cycle threshold, execute at least one second subsequent cleaning cycle using the one or more default cleaning cycle parameters to wash a third set of the one or more articles, wherein each cleaning cycle of the at least one second subsequent cleaning cycle has a longer total duration than each of the cleaning cycles of the second set of consecutive cleaning cycles.

2. The automated cleaning machine of claim 1 ,
wherein the one or more default cleaning cycle parameters specify at least one of a default wash phase duration, a default rinse phase duration, a default detergent concentration, a default wash water temperature, or a default rinse water temperature,
wherein the one or more short cleaning cycle parameters specify at least one of a short cycle wash phase duration, a short cycle rinse phase duration, a short cycle detergent concentration, a short cycle wash water temperature, or a short cycle rinse water temperature, and
wherein the short cycle wash water temperature is relatively higher than the default wash water temperature.

3. The automated cleaning machine of claim 2 ,
wherein the short cycle detergent concentration is relatively higher than the default detergent concentration,
wherein the short cycle rinse water temperature is relatively higher than the default rinse water temperature, or
wherein the short cycle wash phase duration is relatively less than the default wash phase duration.

4. The automated cleaning machine of claim 2 , wherein the short cycle wash phase duration and the short cycle wash water temperature are sufficient to transfer at least 3600 Heat Unit Equivalents (HUEs) to articles in the wash chamber of the automated cleaning machine.

5. The automated cleaning machine of claim 1 , wherein the first predetermined number of cleaning cycles is based on a type of the automated cleaning machine.

6. The automated cleaning machine of claim 1 , wherein the short cycle threshold is based on a type of the automated cleaning machine.

7. A method comprising:
storing, in at least one storage device of an automated cleaning machine that has a wash chamber configured to receive one or more articles to be cleaned, one or more default cleaning cycle parameters associated with a default cycle mode and one or more short cycle cleaning cycle parameters associated with a short cycle mode, wherein the one or more articles are not component parts of the automated cleaning machine and are configured to be inserted and removed from the automated cleaning machine;
executing, by the automated cleaning machine, a first set of consecutive cleaning cycles using the one or more default cleaning cycle parameters to wash one or more first sets of the one or more articles;
determining, by a controller of the automated cleaning machine, first time durations between at least a first predetermined number of cleaning cycles in the first set of consecutive cleaning cycles;
determining, by the controller, that the first time durations satisfy a short cycle threshold; and
in response to determining that the first time durations satisfy the short cycle threshold, executing, by the automated cleaning machine, at least one first subsequent cleaning cycle using the one or more short cleaning cycle parameters to wash a second set of the one or more articles;
executing, by the automated cleaning machine, a second set of consecutive cleaning cycles using the one or more short cleaning cycle parameters, wherein the second set of consecutive cleaning cycles includes the at least one first subsequent cleaning cycle, and wherein the cleaning cycles of the second set of consecutive cleaning cycles have shorter total cycle durations than the cleaning cycles of the first set of consecutive cleaning cycles;
determining, by the controller, second time durations, the second time durations being between at least a second predetermined number of cleaning cycles in the second set of consecutive cleaning cycles;
determining, by the controller, that the second time durations do not satisfy the short cycle threshold; and
in response to determining that the second time durations do not satisfy the short cycle threshold, executing, by the automated cleaning machine, at least one second subsequent cleaning cycle using the one or more default cleaning cycle parameters to wash a third set of the one or more articles, wherein each cleaning cycle of the at least one second subsequent cleaning cycle has a longer total duration than each of the cleaning cycles of the second set of consecutive cleaning cycles.

8. The method of claim 7 ,
wherein the one or more default cleaning cycle parameters specify at least one of a default wash phase duration, a default rinse phase duration, a default detergent concentration, a default wash water temperature, or a default rinse water temperature,
wherein the one or more short cleaning cycle parameters specify at least one of a short cycle wash phase duration, a short cycle rinse phase duration, a short cycle detergent concentration, a short cycle wash water temperature, or a short cycle rinse water temperature, and
wherein the short cycle wash water temperature is relatively higher than the default wash water temperature.

9. The method of claim 8 ,
wherein the short cycle detergent concentration is relatively higher than the default detergent concentration,
wherein the short cycle rinse water temperature is relatively higher than the default rinse water temperature, or
wherein the short cycle wash phase duration is relatively less than the default wash phase duration.
