Abstract
Description
La présente invention concerne une couverture chauffante de dessus. The present invention relates to an overhead heating blanket.
On connait dans l état de la technique un certain nombre de couvertures de ce type. Toutes ces couvertures sont équipées d un thermostat permettant de réguler la température à un niveau désiré et en tout état de cause toujours inférieur à un niveau maximal dit de sécurité. A certain number of covers of this type are known in the state of the art. All these covers are fitted with a thermostat making it possible to regulate the temperature to a desired level and in any case always lower than a maximum level called safety.
Cependant. ces -couvertures chauffantes présentent un certain nombre d'inconvénients, notamment au niveau de la fiabilité de fonctionnement du thermostat et de son prix. augmentant d autant le prix de revient dune telle couverture chauffante. However. these heating blankets have a certain number of drawbacks, in particular in terms of the reliability of operation of the thermostat and of its price. correspondingly increasing the cost price of such a heating blanket.
Le but de l invention est donc de résoudre ces problèmes en proposant une couverture chauffante dont la structure soit telle qu il ne soit plus nécessaire d utiliser de thermostat qui régule en l ab- sence de calorifuge pour 1 empêcher d atteindre une température excessive jugée dangereuse. mais qui soit simple. fiable et d un prix de revient peu élevé. The object of the invention is therefore to solve these problems by providing a heating blanket the structure of which is such that it is no longer necessary to use a thermostat which regulates in the absence of thermal insulation to prevent it from reaching an excessive temperature considered dangerous. . but that is simple. reliable and inexpensive.
A cet effet l invention a pour objet une couverture chauffante de dessus. du type comprenant un élément chauffant régulièrement réparti dans la cou verdure caractérisée en ce que la résistance dudit élément chauffant est supérieure ou égale à U2/3,6.L
2 et inférieure ou égale à U2/3.L où U représente la tension nominale d alimentation de l élément chauf fant. et L la longueur de cet élément chauffant.To this end, the invention relates to a heating blanket from above. of the type comprising a heating element regularly distributed in the greenery, characterized in that the resistance of said heating element is greater than or equal to U2 / 3.6.L
2 and less than or equal to U2 / 3.L where U represents the nominal supply voltage of the phantom heating element. and L the length of this heating element.
On sait que les normes en vigueur en matière de couvertures chauffantes de dessus imposent un certain nombre de conditions notamment au niveau des températures maximales que peuvent atteindre ces couvertures chauffantes. Dans 1 état de la technique. It is known that the standards in force as regards heating blankets from above impose a certain number of conditions in particular at the level of the maximum temperatures which can reach these heating blankets. In 1 state of the art.
ces conditions sont remplies en utilisant des thermos tats régulant 1 alimentation des éléments chauffants des couvertures en fonction de la température atteinte par celles-ci.these conditions are met by using thermostats regulating the supply of the heating elements of the blankets as a function of the temperature reached by the latter.
Ainsi qu il a été mentionné précédemment. ce type de couvertures présente un certain nombre d inconvénients. As previously mentioned. this type of blanket has a number of drawbacks.
La couverture selon l invention permet de remplir ces conditions en n'utilisant pas de thermostat de ce type pour empêcher la couverture d atteindre une température jugée dangereuse. En effet. la Demanderesse a déterminé après différents essais et calculs que si l'élément chauffant. disposé régulièrement dans la couverture chauffante présentait une résistance supérieure ou égale à U2/3,6.L et inférieure ou égale à
U2/3.L où U représente la tension nominale d'alimentation de l'élément chauffant, et L la longueur de ce lui-ci. la couverture chauffante remplissait les différentes conditions imposées par les normes en vigueur et -notamment l'essai de fonctionnement anormal prévu au paragraphe 19 Fig.KR de la norme NFC 73 247 tout en permettant d'obtenir un certain confort. The blanket according to the invention makes it possible to meet these conditions by not using a thermostat of this type to prevent the blanket from reaching a temperature considered dangerous. Indeed. the Applicant has determined after various tests and calculations that if the heating element. placed regularly in the heating blanket had a resistance greater than or equal to U2 / 3.6.L and less than or equal to
U2 / 3.L where U represents the nominal supply voltage of the heating element, and L the length of this one. the heating blanket fulfilled the various conditions imposed by the standards in force and - in particular the abnormal operating test provided for in paragraph 19 Fig.KR of standard NFC 73 247 while allowing a certain level of comfort to be obtained.
