Definitions

  • the present invention relates to a means for accomplishing preventive decontamination of bedbugs and other undesirable arthropods in goods, whereby a thermally insulated casing, which encloses the goods, can be connected to a hot air source or comprises heating elements, and which makes it possible to heat the space formed in the casing at the desired occasion in order to achieve the desired temperature and during the desired time which is sufficient to kill the arthropods by means of circulating hot air, as well as to a device for carrying through preventive decontamination of bedbugs and other undesirable arthropods in suitcases with goods contained therein, whereby a suitcase in question, or a closed casing containing a suitcase, comprises connection for the supply of hot air internally thereto, or that a heating element is provided inside therein, for example in form of a heat producing textile or a heating unit, which is fixedly mounted inside the suitcase, and that means is provided to interrupt the supply of hot air or the heating of the heating element at the desired occasion in order to achieve the desired temperature and the desired time which is sufficient to
  • Another advice is to put the entire suitcase in the freezer for three days and nights. Then, also the eggs are killed, which otherwise could have been missed by the vacuum cleaner.
  • a means to try to kill bugs such as bedbugs previously known for example by WO 2010/096184A2 comprises a completely tight flexible enclosure with an inside, which is so smooth that possible insects slip down from the enclosure to ground level. Further, a source of heat is mounted in the enclosure, but there is not any spreader of the heat. Said enclosure is suitable to decontaminate loose goods and not entire suitcases.
  • WO 2012/027047A1 relates to a collapsible unit consisting of canvas and which is adapted to operate under pressure.
  • a frame work supports the canvas. The entire unit is complicated.
  • GB 2334889A relates to a means which is adapted only to be connectable to a bed mattress in order to kill mites in beds.
  • US 2011/0113674A1 relates to a method and a system for gas treatment of the contents of suitcases.
  • no heat on the outside of the suitcase There is inlet and outlet for gas in the suitcase, and one heats inside the rigid suitcase and measures the temperature when the cover of the suitcase is closed.
  • bulky and not so effective means .
  • the main object of the present invention is therefore in the first place to solve among other things the above mentioned problems by simple and
  • said effectively working preventive means must be easy to handle, non-polluting and lenient to textiles and other objects. Consequently, heating to the temperatures required to kill arthropods does not require higher temperatures than those achievable in a car being in the sun. Usually, this does not damage objects and textiles in the car.
  • a means and a device, respectively, according to the present invention which is primarily characterized in that the casing is double-walled and can be packed together, for example is foldable, can be rolled up or is flexible, so that it can be air evacuated, for example by means of an air suction device, and exhibits a closable opening for the goods in question, whereby hot air is arranged to be directed in the double-walled space in the casing to keep it warm and in an inflated state, and that there are channels or any other double-walled space in the suitcase to supply hot air and to discharge, for example by sucking out, used air from the suitcase when it and the goods contained therein have been warmed up to the desired temperature and during the desired- time .
  • Another indication of the progression of the heating process is the temperature difference between the air blown into the suitcase or the casing and the air which is recirculated. When the suitcase gets warmer this temperature difference will be reduced. If the flow and the heat contents of the incoming air are reduced, an energy-saving effect is achieved at the same time as the energy transfer to the suitcase continues. This is
  • thermocontrol for example by means of a microprocessor or thermostats, which record the outer temperature of the suitcase and/or the temperature of the air coming into and getting out of the casing, respectively.
  • the hot air is spread uniformly along one long side of the suitcase and that the air is then sucked out along the other long side of the suitcase.
  • Devices for spreading hot air in suitcases can advantageously be made on suitcases in such a way that the only remaining measure is to couple a hose to the suitcase from a heating unit and/or then possibly to enclose the suitcase in a casing, which is heated to the desired temperature during the desired time.
  • Heating a suitcase may also be effected by covering surfaces in the suitcase with heat producing textiles or by mounting a light heating unit fixedly in the suitcase .
  • Said flexible casing may be heat- insulated, but also be made in one layer, airtight without insulation if the effect and the air flow are increased to the required extent. This is to obtain a smaller volume when the flexible casing is rolled up. It is also possible to make the casing in two layers, between which air is filled. This air may be supplied by a fan or by inflation by means of a pump or the mouth. This method provides a good heat insulation combined with a small rolled up volume .
