Description

A TEXTILE TREATMENT DEVICE FOR IDENTIFYING THE TEXTILE TYPE
The present invention relates to a textile treatment device for identifying the textile type.
In laundry washing and/or drying machines, parameters such as the amount of water and/or detergent used, water temperature, etc. differ in terms of washing/drying performance and energy consumption according to the textile type. Similarly, the same applies to other clothes treatment devices, such as irons. There are embodiments wherein the textile type is entered to the device by user selection. However, such operational parameters must be able to be set by the device without error, especially in automatic programs. In the state of the art, the textile identification process is often performed optically and unfortunately the results do not provide the desired precision. Due to the nature of optical processing methods, high processing power is required for precise results, which increases production costs. It is a desirable feature in the sector that the textile type can be identified in a more easy and low-cost manner.
In the state of the United States Patent Application No. US2003019253, a device is disclosed, wherein the textile type is identified electromagnetically.
In the state of the art United States Patent Application No. US2013260625, a device is disclosed, wherein fibers accumulating on the clothes are removed by using the triboelectric effect.
In the state of the art International Patent Application No. WO2005073452, a device is disclosed, wherein the static charge on the clothes is measured by using the triboelectric effect.
The aim of the present invention is the realization of a textile treatment device for precisely identifying the textile type.
The textile treatment device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a control unit which evaluates the triboelectric signal generated by the contact of the sensor having a conductive electrode coated with a non-conducting material with clothes so as to identify the textile type. The electrical signal generated by the contact of different materials with each other is characteristic, and if one of the materials is known, the other one can be identified. In the textile treatment device of the present invention, this effect is utilized and the textile type is identified by means of the sensor touching the clothes. The characteristic information between the materials is recorded in the control unit by the producer, and the control unit identifies the textile type by comparing the measured signal.
In an embodiment of the present invention, a sensor unit comprising a plurality of sensors is used in the textile treatment device in order to increase the sensitivity of the identification of the textile type. By increasing the number of measurements, the accuracy rate in identifying the textile type is increased. In a different version of this embodiment, different material coatings are used on different sensors in the sensor unit, and the variety of measurements taken is increased. Using the correlation of measurements from the coatings with different characteristics, the textile type is identified accurately.
In another embodiment of the present invention, the textile treatment device is not only a device for identifying the textile type, but a textile treatment device such as washing machine, dryer, iron, etc. The control unit determines the operating parameters of the textile treatment device to be specific to the specified textile type. For example, in the washing machine, the control unit automatically determines more delicate washing settings for clothes which are determined to be woolly by the sensor. The sensors may be positioned on the cover, if any, of the textile treatment device or on the body of the device so that the user can scan the clothes before placing the same into the device.
Detailed Description of the Invention
The textile treatment device comprising a sensor having a conductive electrode. When the sensor having the conductive electrode gets into contact with the clothes, parameters such as the degree of dryness of the clothes, etc. are enabled to be measured. For example, in dryers the degree of dryness of clothes is determined by measuring conductivity with the conductive electrodes.
The textile treatment device of the present invention comprises a sensor having a non-conductive coating on the electrode, and a control unit which detects the signal resulting from the triboelectric effect generated when the sensor contacts the clothes and which identifies the textile type by comparing the measured signal value with the values stored in the memory thereof. The triboelectric effect, which is the cause of static electrification, is the name given to the process of electron movement which occurs as a result of the contact of different materials with each other. The forces generated when the materials get in contact with each other are electrical, and different charges are collected at the contact region at the moment of contact, and when the contact is interrupted, the opposite charges are trapped in the contact region and the materials are charged with countercharge since the charge change process cannot be reversed quickly. Moreover, charge change occurs between the materials by the effect of friction, and the material is statically electrified. The amount of charge or change of charge occurring during this process varies according to the type of materials. Thus, if one of the materials in contact is known, the other can be known.
In the textile treatment device of the present invention, the conductive electrode is coated with a known non-conducting material, and the charge change caused by the contact of the non-conducting material with the clothes is detected by the electrode. The producer prerecords in the memory of the control unit the amount of triboelectric charge and charge change which occur between the different clothes and the non-conducting material on the sensor. When the user touches/rubs his/her clothes on the sensor using the textile treatment device, the control unit compares the signal received from the sensor with the values in the memory thereof, thus identifying the textile type.
In an embodiment of the present invention, the textile treatment device comprises a sensor unit composed of a plurality of sensors, and the control unit provides the identification of the textile type by evaluating signals received from different sensors. By increasing the number of measurements by using a plurality of sensors, the sensitivity of textile type identification is increased.
In another embodiment of the present invention, the sensor unit has coatings each produced from a different material. In this embodiment, the coating on each sensor is produced from a different material. In this way, the number of measurements is increased while the sensitivity of textile type identification is increased by using the correlation of signals from different coating materials and an almost exact result is achieved.
In another embodiment of the present invention, the control unit determines the operational parameters of the textile treatment device according to the textile type. In case the textile treatment device is not a stand-alone device, where only the textile type is identified, and is a device such as washing machine, dryer, iron, etc., the control unit, after the textile type is identified, determines the operational parameters of the device according to said information, thus providing an automatic process which does not require any user intervention.
In a version of this embodiment, the textile treatment device is a washing machine, and the control unit determines parameters such as the amount of water/detergent, the amount of softener, the movement of the drum, the rotational speed of the drum, etc. according to the identified textile type.
In a version of this embodiment, the textile treatment device is a dryer, and the control unit determines parameters such as the drying temperature, the time, the fan speed, the drum speed, etc. according to the identified textile type. The parameters determined by the control unit are not limited to those stated herein, and any parameter which is required to be determined according to the textile type and suitable to be controlled by the control unit can be determined by the control unit.
In a version of this embodiment, the textile treatment device comprises a door which enables the clothes to be washed to be placed in the treatment area, and the sensor is positioned on the door. The clothes to be washed are placed in the device, and as the drum of the washing machine or the dryer rotates, the clothes contact the sensor on the door, and the type of clothes in the drum is identified.
In another version of this embodiment, the sensor is positioned on the body of the device. Thus, the user is enabled to touch/scan the clothes to/with the sensor before loading the same into the drum, thus identifying the type of the clothes. The sensors may be positioned on the front wall of the door where the door is located or on the panel of the washing machine or dryer. In this embodiment, the user may be warned that an effective washing and/or drying cannot be performed if he/she desires to treat different types of textiles simultaneously.
In another version of the present invention, the textile treatment device is an iron, and the control unit determines parameters such as the temperature of the soleplate, the steam temperature, the steam flow rate, the amount of steam to be sprayed, the amount of water to be sprayed according to the identified textile type.
By means of the present invention, a precise textile type identification is achieved at a low cost without requiring high processing power. Especially in the clothes treatment devices with automatic programs, a truly automatic program is realized by identifying the textile type without the need for user intervention.
