D E S C R I P C I Ó N OBJETO DE LA INVENCIÓN D E S C R I P C I O N OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un dispositivo calentador de platos portátil que aporta, a la función a que se destina, ventajas y características, que se describirán en detalle más adelante, que suponen una destacable mejora del estado actual de la técnica. The invention, as expressed in the statement of the present specification, refers to a portable plate warming device that provides, to the function to which it is intended, advantages and characteristics, which will be described in detail below, which represent a remarkable improvement of the current state of the art.
Más concretamente, el objeto de la invención se centra en un dispositivo calentador de platos que tiene como característica principal que lleva incorporadas unas baterías, lo que permite su traslado a la mesa y mantener el calor y la temperatura del plato mientras este está en la mesa, sin que sea necesaria su conexión mediante cable a la red, y mantener a una temperatura controlada, constante y homogénea la superficie de la placa del mismo sobre la que se incorporan los platos. More specifically, the object of the invention is focused on a plate heating device whose main feature is that batteries are incorporated, which allows its transfer to the table and maintain the heat and temperature of the plate while it is on the table , without its connection by cable to the network being necessary, and maintaining the surface of the plate on which the plates are incorporated at a controlled, constant and homogeneous temperature.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de aparatos y dispositivos electrodomésticos, centrándose particularmente en el ámbito de los destinados a mantener el calor de los platos en la mesa. ANTECEDENTES DE LA INVENCIÓN The field of application of the present invention is part of the industry sector dedicated to the manufacture of household appliances and devices, focusing particularly in the field of those intended to maintain the heat of the dishes on the table. BACKGROUND OF THE INVENTION
Es conocida la utilización de dispositivos calienta platos, cuya finalidad es mantener la temperatura de los alimentos cuando se sirven a la mesa, evitando que se enfríen mientras los comensales se los sirven en el plato. Ello es especialmente importante en determinados tipos de plato, como pueden ser las carnes a la piedra, que se sirven en losas calientes. The use of devices for heating dishes is known, whose purpose is to maintain the temperature of food when they are served at the table, preventing them from cooling while diners serve them on the plate. This is especially important in certain types of dishes, such as stone meats, which are served in hot slabs.
Sin embargo, los calienta platos existentes, o bien son simplemente bandejas de soporte con un alojamiento inferior en el que se incorporan pequeñas velas, con lo cual, la temperatura no se puede controlar, no es constante, pues va aumentando en el punto de incidencia de la llama y tampoco es homogénea, ya que en el punto o puntos de incidencia el calor se mantiene y aumenta, mientras que fuera de dichos puntos la temperatura puede ser muy inferior, o bien se trata de aparatos complejos que se alimentan eléctricamente a base de cable de conexión a la red, con lo cual, su ubicación en la mesa se complica, ya que hay que disponer de una toma cercana o de cable suficientemente largo, cosa que no siempre sucede, especialmente en el caso de que se utilice en establecimientos de restauración, donde las salas de mesas de comensales pueden ser muy amplias y las mesas quedar muy alejadas de algún punto de toma de corriente. However, they are heated by existing dishes, or they are simply support trays with a lower housing in which small candles are incorporated, with which, the temperature cannot be controlled, it is not constant, as it increases at the point of incidence of the flame and is also not homogeneous, since at the point or points of incidence the heat is maintains and increases, while outside these points the temperature can be much lower, or they are complex devices that are powered electrically by means of a network connection cable, whereby their location on the table is complicated, since it is necessary to have a close or long enough cable outlet, something that does not always happen, especially in the case that it is used in catering establishments, where the dining room tables can be very wide and the tables are very away from any electrical outlet point.
El objetivo de la presente invención es, pues, desarrollar un innovador dispositivo para calentar y mantener el calor de los platos en la mesa que evite los inconvenientes señalados. The objective of the present invention is therefore to develop an innovative device for heating and maintaining the heat of the dishes on the table that avoids the aforementioned drawbacks.
Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, si bien como se ha dicho se conocen otros aparatos y dispositivos del tipo que aquí concierne, al menos por parte del solicitante, se desconoce la existencia de ninguno que presente unas características técnicas, estructurales y constitutivas iguales o semejantes a las que concretamente presenta el que aquí se preconiza, según se reivindica. On the other hand, and as a reference to the current state of the art, it should be noted that, although it has been said that other devices and devices of the type that are concerned here are known, at least on the part of the applicant, the existence of none that present technical, structural and constitutive characteristics equal to or similar to those specifically presented here, as claimed.
EXPLICACIÓN DE LA INVENCIÓN Así, el dispositivo calentador de platos portátil que la invención propone se configura como una novedad dentro de su campo de aplicación, estando los detalles caracterizadores que lo distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. De manera concreta, lo que la invención propone, como se ha apuntado anteriormente, es un dispositivo calentador de platos que, ventajosamente, lleva incorporadas unas baterías, lo que permite su traslado a la mesa y mantener el calor y la temperatura del plato mientras este está en la mesa, sin que sea necesaria su conexión mediante cable a la red, permitiendo mantener a una temperatura controlada, constante y homogénea en la superficie de la placa con que cuenta y sobre la que se incorporan platos o las mencionadas losas o piedras. EXPLANATION OF THE INVENTION Thus, the portable plate warming device that the invention proposes is configured as a novelty within its scope, the distinguishing details being conveniently set forth in the final claims that accompany the present description. Specifically, what the invention proposes, as noted above, is a plate warming device that, advantageously, incorporates batteries, which allows its transfer to the table and maintain the heat and temperature of the dish while it is It is on the table, without its connection by cable to the network being necessary, allowing to keep at a controlled, constant and homogeneous temperature on the surface of the plate it has and on which plates or the mentioned slabs or stones are incorporated.
Para ello, y de manera específica, el dispositivo calentador se configura, esencialmente, a partir de una carcasa contenedora, que preferentemente es de plástico aunque puede ser de cualquier otro material, dentro de la cual se incorporan una o más baterías recargables, y un circuito electrónico de control que regula la carga de las baterías cuando este circuito esté conectado a la red eléctrica mediante un cargador de baterías, al mismo tiempo que permitirá la conexión eléctrica de las resistencias incorporadas a una placa calefactora que se sitúa sobre las baterías, en la parte superior de la carcasa. Dicho circuito electrónico va conectado a dos sensores termopares para controlar la temperatura de la placa superior. Este circuito regula, a través de uno de los termopares la temperatura de la placa, que en principio se establece en 60 grados, de manera que la temperatura sobre la parte superior de la piedra/plato sea de 55 grados aproximadamente, transmitiendo dicho calor a los alimentos incorporados sobre la misma. For this, and specifically, the heating device is configured essentially from a container housing, which is preferably made of plastic, although it can be of any other material, within which one or more rechargeable batteries are incorporated, and a electronic control circuit that regulates the charge of the batteries when this circuit is connected to the mains by means of a battery charger, at the same time that it will allow the electrical connection of the resistors incorporated to a heating plate that is placed on the batteries, in the upper part of the housing. Said electronic circuit is connected to two thermocouple sensors to control the temperature of the upper plate. This circuit regulates, through one of the thermocouples the temperature of the plate, which in principle is set at 60 degrees, so that the temperature above the top of the stone / plate is approximately 55 degrees, transmitting said heat to the foods incorporated on it.
El otro termopar conectado al circuito eléctrico, se establece como sistema de seguridad, de manera que, si el anterior no funciona de forma correcta, desconectar el sistema. The other thermocouple connected to the electrical circuit is established as a safety system, so that, if the previous one does not work correctly, disconnect the system.
Dentro de la carcasa contenedora de las baterías, y sobre estas, se incorpora una capa de fibra de vidrio que hade de aislante térmico entre la placa superior y las baterías. Inside the housing of the batteries, and on these, a fiberglass layer is incorporated that has thermal insulation between the top plate and the batteries.
El circuito electrónico, también regula el funcionamiento para que, cuando el dispositivo se desconecta de la red eléctrica, para desplazarlo a la mesa de los comensales, entren en funcionamiento las baterías para suministrar energía a la placa calefactora superior, de manera que durante un tiempo mantenga la temperatura del plato/piedra y, lógicamente, de los alimentos, hasta que estos sean consumidos. The electronic circuit also regulates the operation so that, when the device is disconnected from the mains, to move it to the table of the guests, the batteries come into operation to supply power to the upper heating plate, so that for a while Maintain the temperature of the plate / stone and, of course, of the food, until these are consumed.
El dispositivo, en uno de sus frontales, dispone de los correspondientes elementos de control para todo ello. The device, in one of its front panels, has the corresponding control elements for all this.
Con respecto a la placa térmica preferentemente, está formada por una chapa metálica, una capa de mica, una resistencia, otra capa mica, y otra chapa metálica. With respect to the thermal plate preferably, it is formed by a metal sheet, a mica layer, a resistance, another mica layer, and another metal sheet.
Con todo ello, el dispositivo permite mantener a temperatura la piedra o platos incorporados sobre el mismo, especialmente con el objetivo de elaborar lo que se conoce como "bistec a la piedra" para mantener la temperatura en una/s piezas de carne desde su elaboración hasta su consumo, aunque lógicamente también sirve para mantener la temperatura de cualquier otro alimento o plato cocinado. El uso comenzará, pues, en la cocina, mientras se elaboran los platos, donde el dispositivo podrá estar conectado a la red eléctrica o no, en función de la carga de las baterías, y finaliza en la mesa de comensales, donde gracias a dichas baterías interiores, convenientemente cargadas, el dispositivo no necesita estar conectado a la red eléctrica. Para ello el dispositivo cuenta con las mencionadas resistencias calefactoras, controladas por una electrónica de control que regula la temperatura de las mismas, previamente ajustada, y con una o más baterías con una electrónica asociada, que controla su estado de carga y descarga. El dispositivo indica la presencia de un cargador de baterías, es decir su conexión, mediante un indicador luminoso que también indica el estado de las baterías, y cuya iluminación es intermitente mientras dicho cargador está conectado a la red. El proceso de carga, se realiza automáticamente, al detectar cargador por parte de la electrónica de las baterías. El indicador luminoso de carga es un led tricolor, con el siguiente funcionamiento: With all this, the device allows to keep the stone or plates incorporated on it at temperature, especially with the aim of elaborating what is known as "stone steak" to maintain the temperature in one / s pieces of meat since its elaboration until its consumption, although logically it also serves to maintain the temperature of any other food or cooked dish. The use will begin, then, in the kitchen, while the dishes are prepared, where the device It may be connected to the electricity network or not, depending on the battery charge, and ends at the table of diners, where thanks to these conveniently charged internal batteries, the device does not need to be connected to the electricity network. For this, the device has the aforementioned heating resistors, controlled by a control electronics that regulates their temperature, previously adjusted, and with one or more batteries with an associated electronics, which controls their state of charge and discharge. The device indicates the presence of a battery charger, that is, its connection, by means of a light that also indicates the status of the batteries, and whose lighting is intermittent while said charger is connected to the network. The charging process is carried out automatically, when the charger is detected by the battery electronics. The charging indicator light is a tricolor LED, with the following operation:
En carga (siempre intermitente): si se ilumina en verde, indica que la batería ya está cargada al 100%, y el cargador se desconectará automáticamente; si se ilumina en amarillo, indica que la batería se está cargando; y si se ilumina en rojo indica que el cargador está conectado, pero la batería no acepta carga, normalmente porque está deteriorada y debe ser sustituida. Charging (always flashing): if it lights green, it indicates that the battery is already 100% charged, and the charger will automatically disconnect; if it lights yellow, it indicates that the battery is charging; and if it illuminates in red it indicates that the charger is connected, but the battery does not accept charge, usually because it is damaged and must be replaced.
Si durante la carga, si se pulsa el interruptor on/off con que cuenta el dispositivo, el control de temperatura se inicia, indicándose mediante un segundo indicador luminoso de temperatura, en este caso un led azul, que se ilumina en intermitente inicialmente y pasa a ser fijo cuando se alcanza la temperatura deseada, escogida a través del correspondiente selector. Una segunda pulsación del interruptor on/off detiene la calefacción. If during charging, if the on / off switch available to the device is pressed, the temperature control starts, indicated by a second temperature indicator light, in this case a blue LED, which is initially flashing and passes to be fixed when the desired temperature is reached, chosen through the corresponding selector. A second press of the on / off switch stops heating.
En descarga: cuando se ha desconectado el cargador, para realizar el servicio en la mesa de comensales, el indicador luminoso de temperatura, es decir el led azul, se ilumina de modo fijo, mientras la batería dispone de carga y la temperatura es correcta, y se apaga cuando las baterías no disponen de suficiente energía para mantener dicha temperatura. In unloading: when the charger has been disconnected, to perform the service at the dinning table, the temperature indicator light, that is to say the blue LED, lights solidly, while the battery has a charge and the temperature is correct, and turns off when the batteries do not have enough power to maintain that temperature.
Cuando esto pasa, es decir, cuando la baterías ya no disponen de suficiente energía como para mantener la temperatura escogida, el indicador luminoso de carga se enciende con el led rojo en modo de destellos, indicando que el control de temperatura se ha desactivado para no descargar más y no deteriorar las baterías, que deben ser cargadas de nuevo conectando el cargador. When this happens, that is, when the batteries no longer have enough power to maintain the chosen temperature, the charging light turns on with the red LED in flash mode, indicating that the temperature control has been deactivated to Do not discharge more and do not damage the batteries, which must be recharged by connecting the charger.
Pasado un lapso de tiempo, la electrónica se auto-desconecta (apagado automático), para no descargar completamente las baterías cuando su nivel de carga es muy bajo, con lo cual los indicadores luminosos están apagados. After a period of time, the electronics auto-disconnect (automatic shutdown), so as not to completely discharge the batteries when their charge level is very low, so that the indicator lights are off.
Además, si durante el servicio, se pulsa el interruptor, las resistencias calefactoras se desconectarán. In addition, if the switch is pressed during service, the heating resistors will be disconnected.
El ajuste de temperatura, se puede realizar mediante un pequeño selector asociado a un potenciómetro situado en la parte frontal del equipo, junto al interruptor on/off y al conector para el cargador de baterías. El descrito dispositivo calentador de platos portátil representa, pues, una innovación de características estructurales y constitutivas desconocidas hasta ahora, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. DESCRIPCIÓN DE LOS DIBUJOS The temperature setting can be done using a small selector associated with a potentiometer located on the front of the device, next to the on / off switch and the connector for the battery charger. The described portable plate warming device thus represents an innovation of structural and constitutive characteristics unknown until now, reasons that, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
