Definitions
- the present invention relates to a laundry device for placing in a drum of a washing machine during a washing cycle, particularly to a laundry device comprising a Bluetooth communication module for communication with a separate device outside of the drum.
- washing machines are used for laundering articles, such as clothes and household linens.
- Laundry products including detergent and often fabric conditioners, are added to the wash.
- products are added via a drawer in the washing machine.
- products are added directly to the 10 drum. At its simplest, this may be sprinkling laundry detergent flakes on top of articles to be laundered before the wash cycle begins.
- liquid detergents are introduced into the drum via a dosing ball. Dosing balls are typically small plastic receptacles into which a consumer pours a measured amount of liquid detergent product. The user cannot communicate with or affect in any way, the laundry product within the drum of the washing machine once the washing cycle has started.
- Laundry devices other than dosing balls may be inserted into the drum of a washing machine to aid the washing process.
- "dryer balls” or other laundry balls having a rough or spiky exterior may be placed into a wash to interact with the items being washed.
- This invention aims to provide a mechanism for communicating with devices inside the drum of a washing machine during a washing cycle.
- the present invention aims to solve the above problems by providing, according to a first aspect, a laundry device for placing in a drum of a washing machine during a washing cycle, the laundry device comprising: a waterproof housing; and a wireless communication module located within the waterproof housing for communication with a separate device outside of the drum.
- the wireless communication module operates at a frequency of 2.4 to 2.5 GHz. In some embodiments, the wireless communication module operates at a frequency of 2.4 to 2.485. It was previously thought that wireless communication with a device inside of a washing machine during the washing process would not be possible. The applicant has discovered that washing programs of different types within washing machines of different types and manufacturers exhibit communication windows within which it is possible to communicate wirelessly between devices inside the drum and outside of the drum. In particular, the applicant has discovered that such windows are particularly apparent when working with communication methods at a frequency of 2.4 to 2.5 GHz (such as Bluetooth). The present invention utilizes these communication windows.
- the water content of the load may be reduced enough to enable the signal from the wireless communication module to pass between a device external to the washing machine and the laundry device inside the washing machine.
- a period in which such communications are possible is an example of a communication window.
- the laundry device is configured to determine a current position within the washing cycle.
- the laundry device is configured to send and/or receive signals to the separate device when the current position is equal to a communication window within the washing cycle.
- the communication window is during or immediately after one or more spin cycles of the washing machine.
- the communication module is programmed to send and/or receive signals to the separate device during or immediately after one or more spin cycles of the washing machine.
- a time lag will exist between the end of the spin cycle and the introduction of enough water into the drum to prevent the wireless signal from penetrating into the drum.
- the period after the spin cycle within which a signals can be sent and/or received corresponds to this time lag.
- the length of the time lag will depend upon the fill rate of the washing machine.
- the communication signals may be triggered by a timer within the laundry device.
- the communication signals may be triggered by signals received from sensors located within the laundry device.
- the communication signal could be a signal sent directly from a washing machine to the laundry device, or from a user (e.g. via a mobile device) to the laundry device.
- the Bluetooth communication module is a Bluetooth 2.0 module.
- the Bluetooth communication module is a Low Energy Bluetooth (Bluetooth LE) module. ln this way, a device with an improved lifetime is provided.
- a suitable Low Energy Bluetooth communication module is that of the Texas Instruments CC2650 SensorTag development kit.
- Bluetooth LE Compared to classic Bluetooth, Low Energy Bluetooth, "Bluetooth LE” (or Bluetooth Smart) provides reduced power consumption whilst maintaining a communication range comparable to that of Bluetooth LE.
- the Bluetooth LE communication module may be a Bluetooth 4.0 communication module.
- the laundry device further comprises one or more sensors.
- the sensor devices may be incorporated into or connected to and supported by the communication module.
- the sensor devices comprise one or more of: temperature sensor, humidity sensor, pressure sensor, accelerometer, water sensor, conductivity sensor, gyroscope and magnetometer.
- the laundry device further comprises one or more chambers for a laundry product; wherein the laundry device is configured to retain the laundry product sealed within the one or more chambers and to release at least some of the retained laundry product upon receiving a signal via the Bluetooth receiver to dispense the product into the drum of the washing machine.
- the laundry products includes a fabric conditioner composition.
- a method of communication with a laundry device located within the drum of a washing machine during a washing cycle including: providing a laundry device, the laundry device comprising a Bluetooth
- the separate device within a waterproof housing; providing a separate device located outside of the drum of the washing machine, the separate device comprising a Bluetooth communication module compatible for communication with the laundry device; and establishing a Bluetooth communication channel between the laundry device and the separate device.
- the Bluetooth communication module is a Bluetooth LE communication module.
- the communication module is programmed to establish a Bluetooth communication channel only during or immediately after one or more spin cycles of the washing cycle.
- a communication channel may also be established prior to washing and at the end of the wash program, which will usually correspond to the end of the final spin cycle.

- Example 1 The signal strength between Bluetooth devices within commercial front-loading automatic (FLA) washing machines using two separate signal-generating components was assessed.
- a Texas Instruments CC2650 SensorTag development kit provided a Bluetooth 4. OLE device within the laundry device that could be placed within a washing machine. On activation this device broadcast an 'advertisement' signal for 180s and the strength of this was recorded as it was placed at specific locations within a Miele W1613 FLA machine. To receive the signal we used a Nexus 7 tablet specified to use the same Bluetooth 4. OLE protocol as the SensorTag. This was loaded with the Android application BlueScan to enable capture of the Received Signal Strength Indicator (RSSI, dBm) from each successful connection and record this with time. The values shown below were the mean RSSI over the 180s period after activation of the SensorTag when it was placed at each specified location.
- RSSI Received Signal Strength Indicator
- the Bluetooth 4LE signal strength (in dBm) for a spun load is comparable to that of a dry load. Regardless of the position of the laundry device within the load, the signal strength is great enough for a wireless communication channel to be set up between the laundry device and the separate device outside of the drum (in this case a Nexus tablet).
- the second part of the study was carried out in much the same manner as already described.
- To provide signal measurement during the continuous wash cycles of a range of commercial FLA machines we changed the device used to broadcast a Bluetooth signal to one specified at Bluetooth 2.0 that had no time limitation on its advertisement period.
- the Bluetooth chip was sealed inside a plastic housing to protect it during the wash cycles. Values documented were again the mean RSSI during each of the wash stages, the wash cycles being as noted by the operator.
- Three separate FLA machines were used with the same 4kg load as before.
- sensors could be used in the laundry device, for example, water sensor, thermometer, accelerometer.
- the sensor may be located on the external shell of the washing machine or inside the washing machine, for example in the rinse drawer. Or by using a mobile phone placed in the vicinity of the washing machine, for example on top of the exterior of the washing machine, a sensor in the mobile phone may be used.
- the sensor can detect directly when the rinse water for the final rinse is starting to flow through the rinse drawer. In this manner, the rinse that is detected and measured by the sensor is known to be the final rinse in the washing cycle. The sensor can detect when water is diverted by the washing machine through the rinse drawer, which happens only on the final rinse cycle.
- the laundry device is thereby configured to determine the position in the washing cycle.
- the laundry device is configured to determine the position of the final rinse cycle.
- a signal is sent to the laundry device via wire communication during the communication window in which wireless communications with the laundry device are possible (as described above). That is, when the water has just started to flow into the drum, via the rinse drawer, while the wireless communication with the laundry is still possible.
- the laundry device may be configured to dispense a fabric conditioner composition in to the drum of the washing machine, for example, upon receipt of the wireless signal from the sensor (received via wireless communications).
- the fabric conditioner composition may preferably be dispensed immediately after receipt of the signal by the laundry device.
- the laundry device may wait for a period of time after receipt of the signal before dispensing the fabric conditioner. In this way, the fabric conditioner can be dispensed when the drum of the washing machine is full of water. It will be appreciated from the above description that when the drum has a certain amount of water in it, the wireless communication with the laundry device will be unreliable.
- Sending of signals to the laundry device, and the receipt of signals from the laundry device, may not be possible during at least some times that are outside the
- the signal may be transmitted to the laundry device after the spin (which happens before the rinse water is added) when the drum is generally empty of water. That is, during the communication window.
- the separate device outside of the drum takes the form of a Nexus tablet.
- the separate device could take the form of any computing device with wireless capability.
