Description

  The present invention relates to an ionization apparatus for supplying negative ions to air in a space such as air in a passenger compartment of an automobile. This kind of ionization apparatus includes an emitter means for emitting electrons to accelerate in a heterogeneous electric field so that the electrons ionize gas molecules in the surrounding air, and in the non-uniform electric field. High voltage generating means for generating a high voltage necessary for accelerating the electrons.

  Ions are negatively or positively charged molecules and are present at some concentration in the natural ambient air. In particular, the proportion of negatively charged ions contained in clean air in mountainous areas, air in the ocean region or air after lightning is high. The reason why the air near the waterfall is clean is due to the high concentration of such negatively charged ions.

The higher the proportion of negatively charged ions contained in the ambient air, the higher the human comfort factor (Wohlfuehlfaktor) present in the ambient air. In order to realize this comfort factor, at least 2000 negatively charged ions are usually required in 1 cm ³ of air per person.

  The concentration of negatively charged ions in a closed space is far from the ideal value. Along with temperature and humidity in the air, the concentration of negatively charged ions contained in the air in the space is one of the parameters used to represent the quality of indoor air in building technology.

  From the prior art, ionizers for supplying negative ions to the air in space are known. This conventional ionization apparatus is configured to reproduce the number of negatively charged ions per unit volume of air in the internal space in the natural space. Since the surface of an industrial product exists in the room or the interior space, the content of negatively charged ions that naturally exist in the air in the space is reduced in the room or the interior space. This is especially true in car compartments. This is because the area ratio of the industrial product surface is high.

  Against the background of the above-described prior art, an object of the present invention is to install the following ionization apparatus for supplying negative ions to air in a space, for example, air in the interior of a car, that is, the ionization apparatus. It is an object of the present invention to provide an ionization apparatus that can guarantee that negative ions can be sufficiently supplied to ambient air even in a place of use where the structural space capable of being used is very small.

  According to the present invention, the emitter means of the ionization device is arranged spatially separated from the high voltage generation means of the ionization device, and the emitter means and the high voltage generation means of the ionization device are advantageously arranged. It is solved by connecting with a flexible electrical connection line. In the present invention, the emitter means can be arranged almost arbitrarily in the vicinity of the air discharge portion or the outlet to the internal space, and a separate structural space or attachment is provided for arranging the high voltage generating means of the ionizer. A place can be provided. A reliable and reliable connection between the emitter means and the high voltage generating means is realized by the connection line. The high voltage generating means can be installed at a place in an automobile, for example, where the danger is much less than that at the air outlet or the like and a sufficient installation space or structure space is obtained.

1 shows a first embodiment of an ionization apparatus of the present invention for supplying negative ions to air in space. 2 shows a second embodiment of the ionization apparatus of the present invention.

  Advantageously, the emitter means of the ionization device according to the invention is a sharp emitter, and the electric field generated inhomogeneously in the sharp emitter can be generated using a DC voltage. As a result, the electrons can be reliably accelerated greatly so that the content of negatively charged ions in the ambient air can be significantly increased by ionizing gas molecules in the ambient air.

  Preferably, the electrical connection line between the emitter means or the sharp emitter and the high voltage generating means is a coaxial cable having at least an inner conductor and an outer conductor. As a result, there is no danger to the vehicle occupant, and the rescuer is not exposed to danger when an accident occurs and the rescuer is dispatched.

  In the above-described embodiment, the outer conductor of the coaxial cable is preferably connected to a potential that is higher than the vehicle ground potential by a maximum settable voltage value. The potential connected to the outer conductor of the coaxial cable is, for example, 60V higher than the vehicle ground potential. This makes it possible to ensure that the emitter means or pointed emitter operates reliably even if a voltage of more than 1 kV is required to achieve corona discharge in the emitter means or pointed emitter, For example, interference with electrical or electronic equipment installed in a car is avoided.

  In an advantageous embodiment of the ionization device according to the invention, the ionization device has at least two emitter means or sharp emitters, which are connected to the high voltage generation means of the ionization device. ing. With this configuration, for example, a dedicated emitter means or a dedicated sharp emitter can be provided in each of two separated air exhausts in a car cabin. When these two separated air discharge portions are an air discharge portion provided for the vehicle driver and an air discharge portion provided for the passenger, the vehicle driver and the passenger separately Air with a high concentration of ions can be supplied.

  Advantageously, a surface electrode is arranged in a region around the sharp electrode of the sharp emitter, and the surface electrode is connected to a potential that is much more positive than the potential of the sharp electrode.

  In another advantageous embodiment of the ionization device according to the invention, an electrical connection line between the at least one emitter means and the high voltage generation means is connected to the high voltage generation means via a high resistance resistor. Connecting.

  When the emitter means or the sharp emitter of the ionization apparatus of the present invention is formed so that it can be fixed at the mounting position by a bayonet fixing tool, the emitter means or the sharp emitter can be remarkably easily attached. This also ensures that the seal ring of the bayonet fixture will perform the sealing function when the emitter means or the pointed emitter is attached.

  Hereinafter, the present invention will be described in detail based on embodiments with reference to the drawings.

  The embodiment of the ionization device 1 of the present invention shown in FIG. 1 is used to supply negative ions to the air present in the interior space. In particular, such an ionization apparatus 1 can be used in the interior of an automobile. This is because the proportion of the surface of an industrial product that reduces the content of naturally occurring negative ions in the passenger compartment is very large.

  The ionization device 1 shown in FIG. 1 includes an ionization module or emitter means 2, which is formed as a sharp emitter 2 in the embodiment in the drawing.

  In the case of the sharp emitter 2, a corona discharge method or a tip discharge method is used. In that case, the electrons are greatly accelerated in a very inhomogeneous electric field so that the electrons ionize the gas molecules present in the ambient air. In order to generate an electric field in the sharp emitter 2, a DC voltage is used.

  A sharp electrode belongs to the sharp emitter 2, and a surface electrode is disposed in a region around the sharp electrode. This surface electrode is connected to a potential that is much more positive than the potential at the pointed electrode.

  In order to obtain electric energy necessary for generating an electric field in the sharp emitter 2, high voltage generating means 3 is provided in the ionization apparatus 1. The high voltage generating means 3 can be configured as an electronic circuit box having a lid, for example.

  The high voltage supply means 3 of the ionization apparatus 1 is spatially separated from the sharp emitter 2 of the ionization apparatus 1 and is disposed with a space between the sharp emitter 2.

  In the embodiment of the ionization apparatus 1 shown in FIG. 1, a connection line 4 is provided to connect the sharp emitter 2 and the high voltage generating means 3, and the connection line 4 is a high voltage coaxial cable. 4 is formed. By connecting the sharp emitter 2 of the ionization device 1 and the high voltage generating device 3 by the high voltage coaxial cable 4, the sharp emitter 2 is placed in a small structure space close to the air discharge part to the passenger compartment of the automobile. The high voltage generating means 3 can be mounted or fixed in an appropriate and safe place with little exposure.

  The high voltage coaxial cable 4 of the ionizer 1 has at least an inner conductor and an outer conductor. The outer conductor is connected to a potential 60 V higher than the vehicle ground potential when used in an automobile.

  The high voltage coaxial cable 4 is connected to the high voltage generating means 3 through a high resistance resistor.

  Even if the corona discharge generated in the sharp emitter 2 becomes a voltage exceeding 1 kV due to the above-described configuration of the connection line or the high-voltage coaxial cable 4, for example, other electrical equipment or electronic equipment disposed in the automobile Interference is avoided. Furthermore, the above-described configuration of the high-voltage coaxial cable 4 prevents the vehicle occupant from coming into contact with the high voltage. This is also true when emergency personnel are dispatched in the event of an accident, and the above configuration of the high voltage coaxial cable 4 prevents the emergency personnel from being exposed to high voltage.

  The embodiment of the ionization apparatus 1 of the present invention shown in FIG. 2 is different from the embodiment shown in FIG. 1 in that the high voltage supply means 3 is connected to the high voltage coaxial cables 5 and 6 via the high voltage coaxial cables 5 and 6. It is connected to the two sharp emitters 7 and 8 of the ionizer 1. With such a configuration, for example, when used in an automobile, sharp emitters 7 and 8 can be provided respectively in two separated air discharge portions that supply space air to the automobile compartment. Separately from the passenger, air with high concentration of negative ions can be supplied.

  In the embodiment shown in FIG. 2, the high voltage generating means 3 of the ionization apparatus 1 can be attached to an attachment position at an arbitrary place in the automobile by the fixed lug plate 9, and the high voltage generating means 3 is attached. The distance between the position and the two pointed emitters 7, 8 can be made relatively large.

  The sharp emitters 2 to 7 and 8 of the ionization apparatus 1 of the present invention can be easily fixed at the mounting position or the installation position by the bayonet fixture 10, respectively. Here, the bayonet fixture 10 is provided with a seal ring, and when the sharp emitters 2 or 7 and 8 are fixed to the installation position by the bayonet fixture 10, the seal ring performs a sealing function. Is provided.
