See the Figure 1.
El circuito 14 comprende un condensador 16, un calentador 18 y un ventilador 20. Al menos un perceptor 22 de gas está asociado, también, con el circuito 14 con el fin de detectar la concentración de gas en él, y para permitir el control del grado de secado así como de las condiciones de seguridad en funcionamiento.The circuit 14 comprises a capacitor 16, a heater 18 and a fan 20. At least one gas sensor 22 is also associated with circuit 14 in order to detect the gas concentration in it, and to allow control of the degree of drying as well as the safety conditions in functioning.
De acuerdo con el presente invento, dicho perceptor 22 de gas es un detector de gas por IR, posicionado fuera del circuito 14 para evitar problemas de ensuciamiento. Para la luz en la región del infrarrojo (IR) se sabe que el D5 tiene un espectro de absorción simple e intenso, en el que la altura de los picos está directamente relacionada con la concentración de D5. Como consecuencia, una vez conocida una curva de calibración estándar, puede calcularse fácilmente la concentración real.In accordance with the present invention, said Gas Perceptor 22 is an IR gas detector, positioned outside of circuit 14 to avoid fouling problems. For the light in the region of infrared (IR) it is known that D5 has a simple and intense absorption spectrum, in which the height of the peaks is directly related to the concentration of D5. As a consequence, once a calibration curve is known standard, the actual concentration can be easily calculated.
El perceptor 22 de gas está conectado con el circuito 14 a través de una entrada 24 y una salida 26, de tal manera que el disolvente gaseoso pueda extraerse del circuito y hacerse circular a lo largo de un trayecto óptico 28, después del cual el disolvente gaseoso es introducido de nuevo en el circuito 14. Una fuente de IR 30 y un detector de IR 32 están situados en extremos opuestos del trayecto óptico 28. La fuente de IR emite energía en el intervalo de las bandas de absorción de D5 y esta energía es absorbida por el D5 a lo largo del trayecto óptico y revelada por el detector de IR. Véase la figura 2.The gas sensor 22 is connected to the circuit 14 through an input 24 and an output 26, of such so that the gaseous solvent can be removed from the circuit and circulate along an optical path 28, after which gaseous solvent is introduced back into the circuit 14. An IR source 30 and an IR detector 32 are located in opposite ends of the optical path 28. The IR source emits energy in the range of absorption bands of D5 and this energy is absorbed by the D5 along the optical path and revealed by the IR detector. See figure 2.
Puede preverse un dispositivo de bombeo 34 para mantener el flujo de gas deseado dentro del perceptor 22 de gas; sin embargo, dicho dispositivo de bombeo puede omitirse en el caso de que el detector esté funcionando en una posición fija, hasta que el gas pueda moverse libremente por el trayecto óptico.A pumping device 34 can be provided for maintain the desired gas flow within the gas sensor 22; however, said pumping device can be omitted in the case that the detector is operating in a fixed position, until The gas can move freely along the optical path.
Ventajosamente, el perceptor 22 de gas está encerrado en un sistema termostático 36 para mantener el trayecto óptico 28 y el dispositivo de bombeo 34 a una temperatura dada.Advantageously, the gas sensor 22 is enclosed in a thermostatic system 36 to maintain the path optic 28 and the pumping device 34 at a given temperature.
Otra característica del invento se representa mediante el uso de una pluralidad de perceptores 22 de gas, con el fin de garantizar no sólo el control del grado de secado durante todo el desarrollo del ciclo funcional sino, también, las mejores condiciones de seguridad para el usuario. A este respecto, un primer perceptor 22A de gas está posicionado cerca del condensador 16 para verificar su funcionamiento regular, y un segundo perceptor 22B de gas está asociado con el calentador 18 que es el punto del circuito que tiene la temperatura más elevada. Un tercer perceptor 22C de gas está posicionado cerca de la abertura de carga de la cuba 10, donde puede darse una posible situación de peligro para el usuario.Another feature of the invention is represented. by using a plurality of gas perceivers 22, with the in order to guarantee not only the control of the degree of drying during all the development of the functional cycle but also the best safety conditions for the user. In this regard, a first gas sensor 22A is positioned near condenser 16 to verify its regular operation, and a second receiver 22B of gas is associated with heater 18 which is the point of the circuit which has the highest temperature. A third perceiver 22C of gas is positioned near the loading opening of the tank 10, where there may be a possible dangerous situation for the Username.
Todos los perceptores 22 de gas están conectados con un dispositivo de control electrónico 38 de cualquier tipo conocido, que trate los datos procedentes de los perceptores y que emita las entradas necesarias para activar la máquina lavadora de limpieza en seco. De preferencia, los perceptores 22 de gas son alimentados selectivamente y sus señales se tratan de forma continua.All gas sensors 22 are connected with an electronic control device 38 of any kind known, that treats the data coming from the recipients and that issue the necessary inputs to activate the washing machine dry cleaning Preferably, the gas receivers 22 are fed selectively and their signals are treated in a way keep going.
Alternativamente, puede utilizarse solamente un perceptor 22 de IR (fig. 3) con solamente un dispositivo 34 de bombeo de gas. En este caso, el perceptor de gas está conectado a través de una válvula 40 de múltiples vías, con los conductos 24 para llevar el gas desde el circuito 14 en los puntos seleccionados del mismo. La válvula 40 de múltiples vías es hecha funcionar selectivamente por el dispositivo de control de la máquina en forma conocida. Solamente un conducto 26 de retorno conecta el perceptor 22 de gas por IR con el circuito 14 para reintroducir el gas en el mismo.Alternatively, only one can be used IR receiver 22 (fig. 3) with only one device 34 of gas pumping In this case, the gas sensor is connected to through a multi-way valve 40, with ducts 24 to carry the gas from circuit 14 at the selected points of the same. The multi-way valve 40 is operated selectively by the machine control device in form known. Only one return conduit 26 connects the sensor 22 of gas by IR with circuit 14 to reintroduce the gas into the same.
Las ventajas del presente invento pueden resumirse como sigue. Se obtiene una medición en tiempo real de la concentración de D5 en la fase gaseosa. Se realiza una medición directa de la concentración, en lugar de una medición derivada, como ocurre al utilizar otras técnicas de muestreo. Es posible la miniaturización de los perceptores, de forma que a la máquina se le pueda aplicar una clase real de perceptor.The advantages of the present invention can Summarize as follows. A real-time measurement of the D5 concentration in the gas phase. A measurement is made direct concentration, instead of a derived measurement, as happens when using other sampling techniques. It is possible the miniaturization of the perceivers, so that the machine is can apply a real kind of perceiver.
