Definitions

  • the invention relates to a drying system, in particular for drying objects such as clothing and pieces of equipment, the objects being able to be hung up or placed on drying hangers.
  • Drying systems of this type are known in the prior art for drying items of clothing.
  • the garments are preferably workwear such. B. for the fire brigade, mining companies, military, medical companies, etc.
  • the drying systems usually have drying hangers formed from tubes, the shape of which is approximately adapted to the garment to be dried.
  • the drying hanger has a plurality of air outlet openings, through which compressed air, which is conducted through the tube and possibly heated, can flow and escape from the air outlet openings. It is therefore possible to dry items of clothing and protective clothing such as helmets, masks, etc. from the inside or, due to the air turbulence that occurs at the air outlet openings on the drying hangers, also from the outside. This is particularly necessary for special clothing that is waterproof and made of heavy materials. These materials are slow to dry unless special drying equipment is used.
  • drying systems have a frame or a box open to the front, in the upper area of which an air distribution pipe is guided, which on the one hand can supply warm air to the drying irons and which on the other hand also serves as a suspension device for the drying irons.
  • Drying devices of this type generally work with drying air temperatures between 30° C. and 50° C., so that on the one hand the desired drying effect is achieved and on the other hand the items of clothing are not damaged by temperatures that are too high.
  • the present invention solves the problem of achieving the necessary higher temperature in a drying system, which should usually be between 60° C. and 80° C., and still being able to carry out the drying at a lower air temperature.
  • a temperature as high as 80°C would be too high for the drying air temperature to be introduced into the garments.
  • the drying hangers are arranged in a thermally insulated drying cabinet which can also be heated. This means that the items of clothing and equipment can be attached to the drying hanger and hung in the drying cabinet, which can also be heated.
  • the drying cabinet is thermally insulated to save energy.
  • the drying cabinet is provided with a floor, a ceiling, left and right side walls, a rear wall and an openable and closable front wall.
  • the drying hangers in the drying cabinet can be or are being charged with hot air from a hot air blower, the drying hangers being provided with one or more air outlet openings along their length.
  • the hot air fan is arranged outside, preferably on the ceiling or inside the drying cabinet, and an air line is routed from the hot air fan to an air distribution pipe to which the drying hangers are connected or can be connected inside the drying cabinet.
  • a heating device is arranged inside the drying cabinet for heating, preferably in the floor area or also on the ceiling or on the sides.
  • the heating device can be an electric heater.
  • the heating device is a hot air blower.
  • the heating device is set up for a cabinet temperature between 60° and 80°C, preferably 65° to 70°C.
  • the hot air blower is set up for a dry air temperature between 30° and 60° C., preferably 40° to 50° C., if necessary also up to 80° C.
  • the cabinet temperature is monitored and controlled by a thermostat.
  • a timer can be provided for the switching times for the heating device and optionally also for the hot air blower.
  • the timer can be part of an electronic controller that is set up to control the switching times for the supply of drying air to the drying irons and for the heating device (16) and to control the temperatures of the drying air and cabinet temperature.
  • the invention is further characterized by a method for drying and decontaminating objects such as clothing and equipment, preferably using the drying system described above.
  • Fig. 1 shows an oblique view of the drying cabinet.
  • Fig. 2 shows an oblique view of the open drying cabinet showing the interior equipment.
  • Figures 3 and 4 show more detail of the two halves of the drying cabinet showing the bottom area.
  • FIG. 5 shows an alternative of the bottom area of a drying cabinet in a purely schematic representation.
  • the drying system comprises a drying cabinet 1, which essentially has a floor 2, a ceiling 3, left side wall 4 and right side wall 5 and a front wall 6, the front wall 6 consisting of two doors, possibly also sliding doors, which are openable and closable. Opening the front wall 6 allows unimpeded access to the interior of the drying cabinet 1 .
  • the rear wall is denoted by 24.
  • the hot air blower 7 which preferably contains a high-quality electric motor and directs the hot air generated into the interior of the drying cabinet 1 via the air duct 8 .
  • a hot air blower 7 is preferably used, which not only generates the strong air flow required, but also gives off the necessary heat.
  • the motor together with the fan can be encased in a housing 25 so that the heat from the motor does not escape unused but is used to heat the air flow. This construction saves energy and also prevents the ambient air from heating up too much, which is particularly desirable in crew quarters.
  • an air blower which is arranged differently, e.g. B. separate from the drying cabinet 1, and which has a heat source in the air line 8 to generate the desired temperature of the drying air.
  • a ventilation opening 23 is arranged for venting the drying cabinet 1, which is located here, for example, on the ceiling 3, or can also be arranged differently.
  • Fig. 2 shows the drying cabinet 1 from a different angle
  • Hot air blower 7 is shown with the air inlet holes 9.
  • the drying cabinet 1 is shown broken in order to show the interior of the drying cabinet 1 better.
  • the insulation 10 for the thermal insulation of the drying cabinet 1 can also be seen.
  • drying hangers 11 , 12 are arranged inside the drying cabinet 1 , for example.
  • the drying hangers 11 are curved tubes suitable for clothes, and the drying hangers 12 are suitable for storing shoes or equipment such as belts, gloves, helmets and masks, etc. This combination of two different drying hangers is optional. It is also possible for just one variant or a larger number of different variants to be hung on drying hangers.
  • the drying irons 11, 12 are above an air distribution pipe 13 with the
  • the drying hangers 11, 12 have air outlet openings 14 distributed over their length, through which the drying air can be guided into the interior of the hanging items of clothing or to the items of equipment on all sides.
  • the drying hangers 11 are attached to the air distribution pipe 13 by means of a coupling 15, which allows easy hooking and unhooking of the drying hanger 11 and allows access of the drying air.
  • a heating device 16 is provided, which is formed by electric heating coils in the present embodiment.
  • the heating device 16 is covered at the top by a grid 21, so that the hot air can easily flow upwards and heat up the entire contents of the drying cabinet.
  • the heating device 16 can also be arranged at other points inside the drying cabinet 1, for example on the side walls 4, 5 or on the ceiling 3.
  • heating device 16 must be provided with appropriate electrical connections and switching devices, only some of which are shown here.
  • the right-hand side wall 5 carries the corresponding operating elements in order to be able to operate the drying system.
  • the Elements is located e.g. B. a temperature display 17, thermostat 18 with its
  • the controls can also be arranged in the door area or above the door with visible heat monitoring.
  • the timer and the associated display and switching elements can be part of an electronic controller that is either attached to the drying cabinet or can be designed as a portable electronic switching device that can be connected via a plug connection or an interface.
  • FIG. 5 shows, for example, another possibility for the design of the heating device 16.
  • this is a hot air blower which blows the hot air through the supply pipe 20 into the lower area, i.e. the floor area, of the drying cabinet 1.
  • the heating can be done, for example, by a heating sleeve 22 that is electrically powered.
  • the floor area can be separated by a grid 21 .
  • the process of drying clothing and equipment can be as follows:
  • each drying hanger 11 extends as far as possible into all parts of the items of clothing.
  • the shoes or pieces of equipment are hung or placed on the drying hangers 12 shown on the right.
  • the drying cabinet 1 is closed and the heating device 16 is set to the desired temperature of about 60° to 80°C, preferably 65° to 70°C.
  • the timer 19 is actuated, for example, to set the heating time until the desired drying time is reached, for example about one hour.
  • the heating device 16 switches off and the hot air blower 7 begins to blow the dry air, which has been heated to about 30° to 60° C., preferably 40° to 50° C., into the air distribution pipes 13 and the drying irons 11, 12 connected to them.
  • the drying time must be made dependent on the particular circumstances.
