Definitions

  • This invention relates to an array of space forming elements of a heating device for heating a space having an open side at its top, the heating device comprising a heat source, a diffuser and a flow device for moving a gas close to the heat source and at a flow velocity through the heat source At least over partial areas of the floor of the room extending diffuser with a flow direction into the room comprises, so that a space in the cold gas is displaced by the heated gas.
  • some prior art heaters include fans.
  • an airflow caused by the fans is uncomfortable for the users.
  • the energy consumption of the radiant heaters according to the prior art is very high.
  • US27789856 discloses a drying apparatus, with reference to FIG. 1 and FIG. 2 in US27789856 directed onto an object to be dried, inter alia, from below a heated air flow to the object.
  • the drying device comprises elements which prevent a flow of heated air from the space surrounding the object.
  • the document JP10038278 describes a device for heating a substantially closed space.
  • US3711958 describes a device for drying a person.
  • the apparatus disclosed in this document does not comprise elements extending substantially parallel to an air flow direction which prevent the flow of heated air from the space surrounding the person.
  • the person skilled in the art recognizes that such a flow of heated and moist air with reference to the object of the in US3711958 disclosed invention is desired.
  • the object of the present invention is to provide an outdoor heater which is characterized, inter alia, by a low energy consumption and by a uniform distribution of heat in a room in which the users are or an object.
  • the space is defined by arranged on the side surfaces of the room space-forming elements, which space-forming elements have an extension substantially in the vertical direction, so that a lateral outflow of the heated air from the room and a vertical outflow through the open side is substantially prevented by the formation of a hot air area in the room, which is favored by the arrangement of the space forming elements.
  • the type of heat source is to be chosen among other things depending on the gas to be heated.
  • the heat source can be, for example, a gas flame or an electrical resistance heater, wherein the gas can be brought into a region adjacent to the heat source, so that the gas is heated.
  • the gas to be heated and also the cold gas is air.
  • the disclosure discussed herein does not exclude the use of a gas or gas mixture having a higher density than ambient gas surrounding the heater, typically ambient air.
  • the gas may further be characterized by poor miscibility with air, in particular the ambient air.
  • the heat source comprises an infrared heating element which heats an object, which object is flowed around by the gas to be heated.
  • the heat source can be combined with the elements of the heater. It can be heated by means of an infrared heater, the diffuser, so that the gas flowing through the diffuser (or diffuser) is heated.
  • elements which form space are essentially planar elements such as, for example, plates made of metal or wood arranged, which are arranged around the space to be heated.
  • the space-forming elements are arranged so that on the one hand by the extension of the space-forming elements, on the other hand by a space surrounding the cold gas, a leakage of the heated gas is prevented from the room.
  • the space-forming elements are usually aligned vertically, provided they do not fulfill any further function described below.
  • the heating device according to the invention may be recessed in a floor, so that the space extends below the floor top edge.
  • the room-forming elements have a height such as about 20,0cm, which is easily overcome by a person.
  • an open side is to be understood as one side of the space in which open side no space-forming element extends. A person can easily enter the room through the open side. Likewise, objects can be introduced into the room via the open side.
  • a cold gas, especially cold air, is heavier than heated air.
  • the invention disclosed herein is based on the fact that the open side of the room is located below a cold ambient gas atmosphere surrounding the room. An outflow of the heated gas through the open side of the room is prevented by the cold ambient gas.
  • the diffuser By flowing the heated gas into the room on the one hand, the cold ambient gas is displaced from the room.
  • the purpose of the diffuser is to avoid a concentrated air flow which would be unpleasant for a person due to a high flow velocity, which flow velocity is required to distribute the heated air flow in a room, and to effect air flow uniformly distributed over a cross sectional area instead of the concentrated air flow , A uniformly distributed over a cross-sectional area airflow must not have a high flow velocity for heating a room, since the heated air is distributed over a surface and not punctiform introduced.
  • turbulence is caused by the inflow of the heated gas.
  • the turbulences can cause a discharge of the heated gas cause the room.
  • the invention discussed herein is based on slowly introducing the heated gas while avoiding turbulence.
  • the diffuser may be formed as a passageway-containing plate member or a flow chamber-comprising cavity.
  • the movement of the heated gas entering the room is slowed down by the inertia of the colder gas in the room. In the case of too high inflow velocity of the heated gas into the room, it is possible for the heated gas to flow directly out of the room.
  • the inflow velocity of the heated gas into the room is to be chosen so that the atmospheric pressure at the top of the room caused by the incoming heated gas is substantially equal to the atmospheric pressure of the cold gas resting above the room, substantially the ambient air, so that Space is formed a so-called hot air lake.
  • Cooling of the heated gas in the space is preferably carried out exclusively by convection.
  • the arrangement according to the invention is suitable inter alia as a heater for outdoor use such as in Schanigärten (public gardens) or at stalls.
  • the heating device may further comprise device which prevent fouling of the heater or ensure the discharge of water from the device.
  • the heater comprising the space-forming elements is characterized in that the diffuser extends over portions of the floor of the room.
  • the diffuser extends over the entire base area of the space to be heated, since such a as even as possible introduction of the heated air in the room can be accomplished.
  • a person or an object that is in the room may be located on the diffuser, so that the person or the object flows around the heated gas and is thus heated.
  • the heating device may comprise a control unit, so that by entering the room by a person or by placing an object in the room, the flow device and the heat source can be activated.
  • the heating device can comprise all control units known to the person skilled in the art, by means of which the heat source and / or the flow device is controlled such that the heating device has the lowest possible energy requirement.
  • the heat source and / or the flow device can be controlled as a function of the size of the persons or objects in the room or the number of people or objects in the room.
  • An embodiment of the heating device may include that a space-forming element is made of a textile and has a cavity enclosing shape and a heatable gas or a heated gas can be introduced by means of a flow device into the cavity, whereby the space-forming element of textile is inflatable ,
  • the textile may be permeable to the heated gas at least in some areas, so that the textile acts as a diffuser in some areas and the heated gas can be introduced into the room through the textile.
  • the heater may include baffles disposed in a region adjacent to the diffuser.
  • the guide surfaces can be arranged in the flow direction of the heated gas before and / or after the diffuser. Fins, which are arranged in front of the diffuser, can cause a uniform flow of the diffuser in a defined angle.
  • Guiding surfaces which are arranged after the diffuser, can cause the uniform flow of the heated gas into the room.
  • the diffuser may also include fins.
  • the guide surfaces can be directed so that a user of the heater is not directly, especially sensitive body parts of the user are not directly flowed by an air flow. Furthermore, the heated gas flowing into the space can be conducted through the diffuser in a flow direction deviating from a vertical direction, so that a direct escape of the heated gas from the space is prevented.
  • the space-forming elements serve as guide surfaces through which a circulating gas flow of the heated gas in the room can be produced.
  • the space-forming elements may be inclined towards the center of space.
  • FIG. 1 1 shows a first embodiment of the inventive arrangement of the space-forming elements in a heating device 1 for heating a space 4 having an open side 3 on its upper side, wherein the heating device 1 comprises a heat source 5, a diffuser 6 formed as a plate with through-holes and a flow device 7 , for moving a gas in the vicinity of the heat source 5 and at a flow rate through the diffuser 6 extending over at least portions of the bottom of the space 4 a flow direction 12 into the space 4, so that a space in the cold gas is displaced by a heated gas.
  • the heating device 1 comprises a heat source 5, a diffuser 6 formed as a plate with through-holes and a flow device 7 , for moving a gas in the vicinity of the heat source 5 and at a flow rate through the diffuser 6 extending over at least portions of the bottom of the space 4 a flow direction 12 into the space 4, so that a space in the cold gas is displaced by a heated gas.
  • the space 4 is defined by arranged on the side surfaces of the space 4 space forming elements 2, which space forming elements 2 have an extension substantially in the direction parallel to the flow direction 12, so that a lateral escape of the heated air from the space 4 substantially prevented is.
  • the arrangement of the space-forming elements 2 thus favors the formation of a hot air area in the space 4.
  • a vertical outflow of air from the room 4 is prevented because of the space-forming elements 2 favored formation of a warm air area in the room 4, since the cold, thus heavier Ambient air substantially prevents rising of the heated air in the space 4.
  • a leakage of the heated gas from the space 4 through the open side 3 is also prevented by the higher density of the cold ambient gas.
  • FIG. 1 shows the flow direction 12 of the gas in partial areas of the heater.
  • the diffuser 6 is a through-hole-containing floor element 8 of the room 4, on which floor element the person 9 is located. By entering the room 4, in particular of the floor element 8 by a person 9, the flow device 7 and / or the heat source 5 can be activated.
  • baffles In a region under the diffuser 6 are arranged baffles, which cause a directing of the gas to the diffuser 6 in a defined direction and with a uniform distribution.
  • the heater 1 has such a large area extension, so that a person 9 or more people standing on the floor element 8 place, with per person 9 a space requirement of about 50,0x50,0cm is to be calculated.
  • the room 4 may be part of an outdoor recreation area for a person 9, such as a designated smoking area, a patio garden or a stall.
  • a zone with a pleasant temperature for the person 9, in particular in the foot region of the person 9 is created in these common areas at low outdoor temperatures.
