Definitions
- the invention relates to a laundry product dosing device for placing in a washing machine drum.
- the invention further relates to use of said device in the laundering of articles.
- 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 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.
- Dosing balls are an efficient way to introduce laundry products such as detergents into a wash: because the product is already within the drum, all of the product is used.
- residues may remain after the wash. These may "carry over" into further washes, and may contribute to a build-up of slime in the drawer and pipes.
- the invention relates to a laundry product dosing device that is sealable with a valve. Accordingly, in contrast to the dosing balls of the prior art, the laundry product in the laundry product dosing device of the present invention is sealed within the device when placed inside the washing machine drum.
- the device has a sensor which senses conditions within the washing machine drum (that is, the conditions experienced by the device). This information enables the device to generate a signal causing the laundry product to be dispensed.
- the present invention relates to a laundry product dosing device for placing in a washing machine, the device having a sensor and a chamber for housing laundry product, the chamber being sealable by a valve, wherein the valve is openable on receipt of a signal.
- the senor, processor, and valve are in electronic communication and the value is configured to open on receipt of a signal.
- the device may be a laundry product dosing device for placing in a washing machine drum, the device comprising a sensor, a processor, and a chamber for housing laundry product, the chamber being sealable by a valve, wherein the sensor, processor, and valve are in electronic communication, the valve being openable on receipt of a signal generated by the processor to dispense laundry product.
- the device comprises a pressure generating means configured to increase the pressure of the laundry product such that pressure is exerted on the valve and the value opens.
- a pressure generating means configured to increase the pressure of the laundry product such that pressure is exerted on the valve and the value opens.
- This may be, for example, a piston arrangement or a bellows system which may primed with a spring and set in motion when it receives the signal from the processor.
- the device of the invention is placed in a washing machine drum before a wash cycle begins. It may be placed on top of the articles to be laundered, as is conventional with a dosing ball, or because the laundry product is sealed within the device at this stage, the device may simply be "gathered up" with the articles to be laundered and placed in the machine. In some cases, the device is suitable for use in a domestic washing machine. Suitably, in some cases, the device is dimensioned to be placed in the drum by hand, for example, it may be dimensioned to sit in an adult user's hand.
- the senor determines conditions within the washing machine drum. In other words, it may be configured to detect conditions within the drum.
- the sensor may detect across a range of conditions, detecting incremental or continuous variation, and feed this information to the processor, or it may simply operate between two states (a first state and second state, which may be simply on and off).
- the sensor may be, without limitation, selected from an accelerometer, a gyrometer (sometimes called a gyroscope), a magnetometer, a thermometer, a microphone, and conductivity meter.
- An accelerometer or gyrometer measures the movement and/or vibration of and within the drum: in detail, an
- accelerometer measures the vibrations experienced by the device inside the drum and a gyrometer measures the orientation of the device with respect to gravity and the rate of rotation of the device.
- a microphone may take a raw sound recording and / or determine the noise volume within the drum.
- a thermometer measures the temperature within the drum.
