Definitions

  • This invention refers to a device to provide hot water for caravans, with considerable advantages over existing systems for similar purposes.
  • the device is designed, one the one hand, to comply with current legislation on gas heaters installed in dwellings and at the same time to produce hot water "instantaneously”.
  • gas heaters with accumulation of water are installed. They heat a 10 or 14-litre tank and have very limited heating power, lower than 4,000 Kcal/h, which is the legal limit. But these existing heaters involve at least two important problems: First, they only supply a small amount of hot water (10 or 14 litres), and secondly, it takes some time for the water accumulated in the tank to be heated, so that if it used for more than one person to shower, the waiting time is considerable and their utility is limited.
  • One objective of this invention is to manufacture an instantaneous gas water heater, with no limitations, that complies with the legislation on installation in caravans.
  • This type of heater has an important problem in that, like all heaters that handle accumulated water, it takes some time for the water to be heated for use. They are also usually very small (around 10 litres), so there is only water enough for one person to take a shower before waiting for the water to be heated again.
  • the device in this invention contains a commercial 5 1/min instantaneous gas water heater, so it has the great advantage that hot water is available immediately, without having to wait, and if it is connected to a large caravan water tank (normally, between forty and sixty litres), there is enough water for four or five people to take a shower without waiting.
  • This commercial heater is integrated in a metal container with a door, prepared to be fitted into one of outer sides of the caravan so that, since it is not inside the caravan but in an outdoor independent area, it complies with current legislation on the installation of heaters in bedrooms and bathrooms.
  • the important characteristics of this metal container is that it has a combustion air and cooling inlet at the bottom with a windbreak and a combustion gas and cooling outlet at the top with another windbreak.
  • the metal container besides being made fire-proof by asbestos panels covered with aluminium reflectant surfaces to dissipate the heat, has an air chamber at the back with natural circulation produced by the different densities of cold and hot air, which cools both the back and the top of the container, preventing them from being heated.
  • the container is hermetically sealed from the inside of the caravan and it also has a regulatory gas spigot and an upper gas outlet, air inlets and gas outlets sized to comply with current legislation.
  • the device that has just been described can present problems depending on the position of the caravan and the intensity of the wind, since the wind can prevent the combustion gases from escaping in certain cases.
  • the exhaust gas escapes by natural cooling, using a vertical conduit approximately 20 cm in length and a minimum interior diameter of 9 cm.
  • One variation of the invention replaced the vertical tube that is the natural draught by a turbine type gas extractor that forcibly expels the combustion gases. This extractor is started automatically when the temperature of the gases produced by the heater exceeds a certain value, and the gas is extracted by means of the natural draught when the level is lower.
  • Figure 1 shows a view of the device that is the object of the invention from the outside of the caravan.
  • Figure 2 shows a view of the side section of the device that is the object of the invention.
  • Figure 3 shows a front view of the device that is the object of the invention.
  • Figure 4 shows a side section view of the device that is the object of the invention with a driven exhaust.
  • Figure 5 shows a front view of the device that is the object of the invention with a driven exhaust.
  • the device consists of a metal cabinet/container with heat insulation on the base (7), walls and ceiling (6), which houses an instantaneous gas heater (1) with a cool air conduit (8) at the back that operated by means of the circulation of air and the effect of different densities, with an orifice and grille on the bottom as an air inlet and a lower windbreak (4) and another orifice and grille on the top to evacuate one the one hand the cool air (9) and on the other the combustion gases (2).
  • This orifice also has an upper windbreak (3) to avoid the effect of the wind.
  • the container/cabinet has a metal door without a lock for access to the heater (1) and on the front is installed the regulatory gas spigot (5).
  • the hot and cold water pipes (10) come through the top of the cabinet.
  • the entire assembly presents a flap (11) around the entire edge so that the equipment can be fitted into one of the outer sides of the caravan, isolated from the inside of the caravan and with access for handling also outdoors, and it does not stand out from the vehicle in order to comply with the regulations regarding mobile vehicles or units in this respect.
  • the device that is the object of the invention works as follows:
  • the air necessary for combustion enters through the edges of the lower windbreak (4) and is divided into two flow streams; one goes through the heater (1) providing the flow required for combustion and is expelled as burnt gas through the gas outlet (2), whereas the second flow goes through the cooling conduit (8) where it cools the heater (1) itself and is finally expelled through the cool air outlet (9), mixing with the hot gases from the combustion gas outlet (2) and cooling them, making use of the turbulence created by the upper windbreak (3).
  • the hot and cold water pipes (10) are connected to the heater (1) from beneath, as can be seen in figure 2.
  • FIGS 4 and 5 we show the version with a driven draught, in which an extractor (12) is connected at the combustion gas outlet (2). Since the extractor (12) that drives the draught must operate at 220 V, 50 Hz so that its motor does not require a brush collector and sparks are therefore not generated, as would be the case for a 12 V direct current motor, since this is the voltage available in the caravan from the battery of the two car, a current converter has been incorporated into the extractor (12) which transforms the 12 V dc to 220 V, 50 Hz.
