Abstract

A method for controlling water spouting of a toilet includes: a target region where a foreign object exists is determined from multiple predetermined regions in the toilet; a target water spout corresponding to the target region is determined according to pre-stored correspondences between the multiple regions in the toilet and water spouts for flushing the multiple regions; and the target water spout is controlled to spout water.

First claim

The invention claimed is:

1. A method for controlling water spouting of a toilet, applied to the toilet comprising a plurality of water spouts, wherein the plurality of water spouts are uniformly distributed in an inner region of a toilet base, and the method comprises:
determining a target region, among a plurality of predetermined regions, where a foreign object exists in the toilet;
determining a target water spout corresponding to the target region according to pre-stored correspondences between the plurality of regions in the toilet and the plurality of water spouts for flushing the plurality of regions; and
controlling the target water spout to spout water.

2. The method according to claim 1 , wherein the determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet comprises:
upon detection of a water spouting triggering event, starting a foreign object detection member; and
determining the target region, among the plurality of predetermined regions, where the foreign object exists the toilet through the foreign object detection member.

3. The method according to claim 2 , wherein the foreign object detection member comprises an image capturing member, an infrared detection member or a sonar detection member.

4. The method according to claim 2 , wherein:
the toilet further comprises at least one supplementary water spout; and
the method further comprises:
upon detection of the water spouting triggering event, controlling the supplementary water spout to spout water for a first preset duration.

5. The method according to claim 2 , further comprising:
acquiring a target account currently logged on to the toilet, and recording the target account and one or more target water spouts corresponding to the target account;
when a first number of times for which the toilet with the target account logged on has been triggered to spout water reaches a preset number of times, determining a water spout, which has been triggered to spout water for a second number of times, from the recorded one or more water spouts corresponding to the target account, wherein a ratio of the second number to the first number exceeds a preset ratio, and taking the determined water spout as a default water spout corresponding to the target account; and
upon detection of the water spouting triggering event again, when an account currently logged on to the toilet is the target account, controlling the default water spout to spout water for a second preset duration.

6. The method according to claim 1 , wherein:
the determining the target region, among the plurality of predetermined regions, where the foreign object exists the toilet comprises:
determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet and an extent of the foreign object in the target region;
the method further comprises: determining a swinging angle range of the target water spout according to the extent of the foreign object in the target region; and
the controlling the target water spout to spout water comprises:
controlling the target water spout to swing in the swinging angle range and spout water.

7. The method according to claim 1 , further comprising: after controlling the target water spout to spout water,
upon detection of a water spouting duration of the target water spout reaches a third preset duration, controlling the target water spout to stop spouting water; or,
upon detection of a spouted water amount of the target water spout reaches a preset spouted water amount, controlling the target water spout to stop spouting water; or,
upon detection of absence of the foreign object in the target region, controlling the target water spout to stop spouting water.

8. The method according to claim 2 , wherein:
the determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet comprises:

determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet and an extent of the foreign object in the target region; and
the method further comprises: determining a swinging angle range of the target water spout according to the extent of the foreign object in the target region; and
the controlling the target water spout to spout water comprises:
controlling the target water spout to swing in the swinging angle range and spout water.

9. The method according to claim 3 , wherein:
the determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet comprises:

determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet and an extent of the foreign object in the target region;
the method further comprises: determining a swinging angle range of the target water spout according to the extent of the foreign object in the target region; and
the controlling the target water spout to spout water comprises:
controlling the target water spout to swing in the swinging angle range and spout water.

10. The method according to claim 4 , wherein:
the determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet comprises:

determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet and an extent of the foreign object in the target region;
the method further comprises: determining a swinging angle range of the target water spout according to the extent of the foreign object in the target region; and
the controlling the target water spout to spout water comprises:
controlling the target water spout to swing in the swinging angle range and spout water.

11. The method according to claim 5 , wherein:
the determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet comprises:

determining the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet and an extent of the foreign object in the target region;
the method further comprises: determining a swinging angle range of the target water spout according to the extent of the foreign object in the target region; and
the controlling the target water spout to spout water comprises:
controlling the target water spout to swing in the swinging angle range and spout water.

12. A terminal for controlling water spouting of a toilet, comprising:
a processor, and
memory arranged to store at least one instruction for the processor,
wherein the processor is arranged to:
determine a target region, among a plurality of predetermined regions, where a foreign object exists in the toilet, the toilet comprising a plurality of water spouts, wherein the plurality of water spouts are uniformly distributed in an inner region of a toilet base;
determine a target water spout corresponding to the target region according to pre-stored correspondences between the plurality of regions in the toilet and the plurality of water spouts for flushing the plurality of regions; and
control the target water spout to spout water.

13. The terminal according to claim 12 , wherein in order to determine the target region, among the plurality of predetermined regions, where the foreign object exists in the toilet, the processor is arranged to:
upon detection of a water spouting triggering event, start a foreign object detection member; and
determine the target
