Abstract

Claims (55)

1. A method for remotely controlling a cleaning cycle of a household appliance using transmission of wireless signals, the wireless signals being transmitted between a mobile dispensing device configured to be arranged in a housing of the household appliance and an external electronic device located outside of the household appliance, the method comprising:

determining a value of a strength of a wireless signal received by the mobile dispensing device;

comparing the determined value of the strength of the wireless signal received by the mobile dispensing device to a threshold signal strength value;

enabling transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is above the threshold signal strength value;

sending a status wireless signal comprising status information about the cleaning cycle, the status wireless signal being sent from the mobile dispensing device to the external electronic device when transmission of wireless signals is enabled during the cleaning cycle; and

disabling transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is below the threshold signal strength value.

2. The method according claim 1 , wherein the value of the strength of the wireless signal is determined by repeatedly obtaining a value of an attenuation of signals received by the mobile dispensing device.

3. The method according to claim 1 , further comprising:

determining a change in the value of the strength of the wireless signal received by the mobile dispensing device over time;

determining a status of the cleaning cycle run by the household appliance based on the determined change.

4. The method according to claim 1 , further comprising:

determining a pattern in values of the strength of the wireless signal received by the mobile dispensing device as a function time; and

identifying contributions to the determined pattern external to the cleaning cycle run by the household appliance.

5. The method according to claim 4 , wherein the identification of contributions to the determined pattern external to the cleaning cycle run by the household appliance is implemented using one among:

comparison of the determined pattern to patterns stored from previous cleaning cycles run by the household appliance; and

input from a user.

6. The method according to claim 4 , further comprising:

recording determined values of the strength of the wireless signal received by the mobile dispensing device; and

generating a report for the external electronic device if the recorded values comprise at least one value that is below the signal strength threshold value.

7. The method according to claim 4 , further comprising:

outputting a recommendation for one among:

a change in a position of the mobile dispensing device inside the household appliance;

a change in a position of a source of wireless signal interferences;

a switching off of the source of wireless signal interferences;

installation of a signal amplifier; and

a change in the position of an access node used to relay information from the mobile dispensing device to the external electronic device.

8. The method according to claim 1 , further comprising:

modifying a program to dispense cleaning agents from the mobile dispensing device into the housing during the cleaning cycle based on information provided in wireless signals received by the mobile dispensing device, the cleaning agents being contained in the mobile dispensing device; and

dispensing the cleaning agents based on the modified program.

9. The method according to claim 1 , wherein an internal electronic device capable of establishing a communication with the mobile dispensing device is located inside the household appliance, the method further comprising:

receiving, at the mobile dispensing device, an internal wireless signal from the internal electronic device providing information on a parameter of the cleaning cycle run by the household appliance; and

determining a change to a program to dispense cleaning agents from the mobile dispensing device into the housing during the cleaning cycle based on the received internal wireless signal.

10. The method according to claim 1 , further comprising:

sending an instruction to change a program to dispense cleaning agents from the mobile dispensing device into the housing, the instruction being sent as a wireless signal from the external electronic device to the mobile dispensing device during the cleaning cycle.

11. The method according to claim 1 , further comprising:

defining at least two wireless signal strength value ranges for signal strength values above the threshold value, the two wireless signal strength value ranges comprising a first signal strength value range and a second signal strength value range, values of strengths of signals belonging to the first signal strength value range being higher than values of strengths of signals belonging to the second signal strength value range;

allowing unrestricted transmission of data upon determining that the strength of the wireless signal received by the mobile dispensing device belongs to the first signal strength value range; and

restricting an amount of data that is transmitted upon determining that the strength of the wireless signal received by the mobile dispensing device belongs to the second signal strength value range.

12. The method according to claim 1 , wherein the wireless signal received by the mobile dispensing device is sent form an access node.

13. The method according to claim 12 , wherein the access node is part of one among: the external electronic device and a wireless communication node part of a wireless network.

14. A system for remotely controlling a cleaning cycle of a household appliance, the system comprising:

a mobile dispensing device configured to be arranged in a housing of the household appliance;

an external electronic device located outside of the household appliance; and

at least one data processing device arranged in the mobile dispensing device and configured to:

determine a value of a strength of a wireless signal received by the mobile dispensing device;

compare the determined value of the strength of the wireless signal received by the mobile dispensing device to a threshold signal strength value;

enable transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is above the threshold signal strength value;

send a status wireless signal comprising status information about the cleaning cycle, the status wireless signal being sent from the mobile dispensing device to the external electronic device when transmission of wireless signals is enabled during the cleaning cycle; and

disable transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is below the threshold signal strength value.

15. A non-transitory computer program product comprising instructions for executing a method for remotely controlling a cleaning cycle of a household appliance using transmission of wireless signals, the wireless signals being transmitted between a mobile dispensing device configured to be arranged in a housing of the household appliance and an external electronic device, the method comprising:

determining a value of a strength of a wireless signal received by the mobile dispensing device;

comparing the determined value of the strength of the wireless signal received by the mobile dispensing device to a threshold signal strength value;

enabling transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is above the threshold signal strength value;

triggering emission of a status wireless signal comprising status information about the cleaning cycle, the status wireless signal being sent from the mobile dispensing device to the external electronic device when transmission of wireless signals is enabled during the cleaning cycle; and

disabling transmission of wireless signals from the mobile dispensing device to the external electronic device when the determined value of the strength of the wireless signal received by the mobile dispensing device is below the threshold signal strength value.
