DESCRIPCIÓN  DESCRIPTION
DISPOSITIVO DE EXTRACCIÓN DE MALOS OLORES PARA INODOROS. Objeto de la invención DEVICE FOR EXTRACTION OF BAD ODORS FOR TOILETS. Object of the invention
La presente invención se refiere a un dispositivo de extracción de malos olores para inodoros, que comprende unos medios destinados a evacuar los malos olores producidos por las necesidades fisiológicas del usuario durante el uso de dicho inodoro, evitando que se extiendan los malos olores por el recinto, en el cual se encuentra instalado dicho inodoro.  The present invention relates to an odor extraction device for toilets, comprising means intended to evacuate odors produced by the physiological needs of the user during the use of said toilet, preventing bad odors from spreading through the enclosure. , in which said toilet is installed.
Campo de aplicación de la invención. Field of application of the invention.
Este dispositivo es aplicable en el sector de la construcción y, más concretamente, en la instalación de sanitarios y accesorios para cuarto de baño y aseos.  This device is applicable in the construction sector and, more specifically, in the installation of sanitary ware and accessories for bathroom and toilets.
Antecedentes de la invención. Background of the invention.
En la actualidad, para evitar el efecto desagradable de los malos olores producidos durante las necesidades fisiológicas de un usuario en el retrete existen una gran variedad de dispositivos y medios, cuya eficacia es bastante limitada.  At present, to avoid the unpleasant effect of the bad odors produced during the physiological needs of a user in the toilet there is a great variety of devices and means, whose effectiveness is quite limited.
Estos olores, tan molestos y desagradables, son a veces un poco vergonzantes cuando se tienen invitados que utilizan el servicio seguidamente y, también, en cualquier lugar público o, sin ir más lejos, para cuando uno mismo lo utiliza.  These odors, so annoying and unpleasant, are sometimes a bit embarrassing when you have guests who use the service next and, also, in any public place or, without going any further, for when you use it yourself.
Son conocidos productos tales como perfumes ambientales, extractores del aire del recinto, la ventilación por la ventana y otros. Pero su utilización no deja de ser incómoda para el usuario, ya que todas estas soluciones basan su acción sobre el aire general del recinto, cuando ya se han esparcido los malos olores.  Products such as environmental perfumes, room air extractors, window ventilation and others are known. But its use is not uncomfortable for the user, since all these solutions base their action on the general air of the enclosure, when the bad smells have already spread.
En el caso de la utilización de los perfumes ambientadores, se mezclan los malos olores con dicho perfumes, resultando una atmósfera cargada. Además estos perfumes ambientadores no siempre son respetuosos con el medio ambiente, al utilizarse en su fabricación productos químicos y sustancias volátiles que pueden ser contaminantes. Con este sistema logramos que ese momento sea menos desagradable para el usuario o para las personas siguientes a utilizar ese lavabo. In the case of the use of air fresheners, they mix bad smells with such perfumes, resulting in a charged atmosphere. In addition, these air freshener perfumes are not always respectful of the environment, when chemicals and volatile substances that can be contaminants are used in their manufacture. With this system we make that moment less unpleasant for the user or for the following people to use that sink.
Los extractores del aire del recinto, ya sea baño o aseo, instalados en la pared del mismo, presentan el problema de que tienen que mover una gran cantidad de aire con los malos olores, por lo que consumen mucha energía para proporcionar la potencia de extracción necesaria. También resultan ruidosos y el efecto es limitado si el recinto es muy grande por el volumen de aire a renovar. Además, se encuentra el problema de que la climatización o calefacción del baño se ve alterado, por ejemplo al abrir ventanas con la temperatura exterior, perdiéndose la temperatura ambiente conseguida.  The air extractors of the enclosure, whether bath or toilet, installed in the wall of the same, present the problem that they have to move a large amount of air with the bad odors, so they consume a lot of energy to provide the extraction power necessary. They are also noisy and the effect is limited if the enclosure is very large due to the volume of air to be renewed. In addition, there is the problem that the air conditioning or heating of the bathroom is altered, for example when opening windows with the outside temperature, losing the ambient temperature achieved.
El solicitante de la presente invención desconoce la existencia de antecedentes que resuelvan de forma satisfactoria la problemática expuesta. Descripción de la invención  The applicant of the present invention is unaware of the existence of a background that satisfactorily solves the problem presented. Description of the invention
