Definitions

  • the present invention relates to a humidifier with a water tank, at least one evaporator block and a fan wheel rotatable about a vertical axis, by means of which room air is sucked in through the evaporator block and returned to the room after moisture absorption.
  • Humidifiers of the generic type are known per se and are distinguished, inter alia, by characterized in that no water pump is required to supply the water to be evaporated to the evaporator block.
  • the humidification of the evaporator block is brought about by immersing a hygroscopic material in the water reservoir of the water tank and thus, to a certain extent, automatically moistening the part of the evaporator block protruding from the water.
  • Hygros tend to water, especially if the water is very hard Copied materials very soon for constipation, so that in this case the evaporator block has to be replaced relatively often.
  • the room air is sucked through the evaporator block at the given room temperature, i.e. the evaporator output, among other things. also depends on the uncontrollable air temperature and is therefore not changeable in this respect.
  • the present invention has for its object to improve a humidifier of the generic type in such a way that while maintaining the advantage of not having to use a water pump, the selection of possible materials for the evaporator block is increased and in addition the possibility is created of the evaporation performance of the humidifier in to vary wide limits.
  • Such a construction makes it possible, on the one hand, to use any materials for the construction of the evaporator block, since the water is supplied to the evaporator block in any case and also without a water pump.
  • This is due to the use of the water delivery pipe of the specified construction, it advantageously being possible for the water delivery pipe to be firmly connected to the fan wheel and thus to be designed to be drivable together with it.
  • the centrifugal disc in connection with the water outlet openings in the upper end area of the water delivery pipe, the water to be evaporated can be supplied to any evaporator block of any design.
  • the possibility is created to heat the sucked-in air and thus to increase the evaporation capacity or, ultimately, to increase the evaporation capacity by varying the heating capacity vary.
  • the advantage is achieved that the air returned to the room is at a pleasant temperature and is therefore subjectively not perceived as "cold air”.
  • the air humidifier designated overall by reference number 10 in FIG. 1 has a housing 11 in which a water tank 12 is arranged.
  • This water tank 12 can be separated from the housing 11 overall in a manner known per se.
  • the humidifier according to the exemplary embodiment shown is provided with two evaporator blocks 13 which are arranged at a distance from one another and, in the exemplary embodiment shown, have the shape of cuboid-like cassettes. These cassettes are filled with an evaporator material, these cassettes are preferably filled with gravel, clay balls or plastic granules or a mixture of gravel, clay balls or plastic granules.
  • a fan wheel 14 is provided in the upper region of the housing 11 and can be rotated about a vertical axis via a motor 15.
  • a water delivery pipe 16 Connected to this fan wheel 14 is a water delivery pipe 16, which projects with its lower end into the water tank 12 and, starting from its lower, open end, widens conically upwards.
  • the upper end region of the water delivery pipe 16 is approximately at the same height as the upper limit of the evaporator blocks 13.
  • a centrifugal disc 17 is provided, which projects laterally beyond the water delivery pipe 16.
  • heating units 20 In the air intake area 19 of the humidifier 10 are in front the evaporator blocks 13 arranged heating units 20. These heating units 20 can be switched on jointly or independently of one another, and there is also the possibility of regulating the energy supply to the heating units 20 and thus also their heating output.
  • the room air sucked in by the fan wheel 14 first passes through the air intake area 19 in which the heating units 20 are arranged and is heated in accordance with the selected heating output.
  • the sucked-in air then passes through the evaporator blocks 13 and is returned to the room through the air outlet area 21.
  • the air absorbs moisture in the desired manner and thus ultimately provides for a desired increase in the air humidity in the room in which the humidifier 10 has been set up and put into operation.
  • the evaporation capacity can be increased and can also be controlled within wide limits with controllable heating capacity. This in turn allows comparatively small evaporation blocks 13 to be used, so that the overall dimensions of the humidifier can also be kept correspondingly small. The escape of cold air from the air Step area 21 is also avoided.
  • the air can be passed through the space between the individual granules relatively easily, so that overall there is only a small air resistance.
  • two cuboidal evaporation blocks 13 are shown, but it is also conceivable to have a single, for example, to arrange annular evaporator block 13.
  • a humidifier can also be equipped with only one evaporation block.
  • the water delivery pipe 16 can be provided in the region of its inner wall with helical or similarly shaped grooves in order to improve the delivery service at a predetermined speed.
