An ion generating device generates O(HO)(where n is a natural number) as negative ions and H(HO)(where m is a natural number) as positive ions, and discharges those ions into the air so that airborne germs are killed through an oxidation reaction by hydrogen peroxide HOor radical hydroxyl OH generated through as an active species a chemical reaction between the negative and positive ions. Satisfactory sterilization is achieved when the negative and positive ions are generated in such a way that the concentrations of the negative and positive ions are both 10,000 ion/cc at a distance of 10 cm from the point at which they are generated.

Sterilization method, ion generating device, ion generating apparatus, and air conditioning apparatus

In order to efficiently kill airborne fungi in a room, an ion generator includes an ion generator, a temperature sensor for detecting a temperature, and a humidity sensor for detecting a humidity. The ion generator is controlled based on a temperature detection result detected by the temperature sensor and a humidity detection result detected by the humidity sensor. As ions are generated in accordance with the temperature and humidity, airborne fungi can efficiently be killed.

Sterilization method

An air conditioning apparatus incorporates an ion generating device that generates positive and negative ions by applying an alternating-current voltage between electrodes. The generated positive and negative ions coexist in the air and, when they attach to the surfaces of airborne bacteria, they react chemically with each other and generate radical hydroxyl and hydrogen peroxide, which extract hydrogen atoms from the cells of the bacteria and thereby kill them. This sterilizing effect is combined with the temperature-conditioning, dehumidifying, humidifying, air-purifying, and other functions of the air conditioning apparatus to bring about a comfortable and healthful indoor environment.

Air conditioning apparatus and ion generating device for use therein

A booster coil is stored in a coil storing room provided in the bottom section of a common case having an opening on one side, and is insulation-molded with a filler. A circuit substrate is inserted into the common case and supported by a supporting edge which is provided circumferentially at the middle of an inner wall of the common case. An ion generating element is held on a lid plate for closing the opening of the common case and mounted on the outer surface of the common case together with this lid plate, and the space between the circuit plate and the ion generating element is insulation-molded with a filler. An ion generator including the ion generating element and the booster coil and circuit substrate for generating a driving voltage is constructed in a compact size so as to enable the ion generator to be readily used in a wide range of applications.

An inner electrode formed inside a dielectric body and a surface electrode formed on a surface of the dielectric body. The surface electrode is formed in a grid pattern with pointed parts formed inside the grid section. Each pointed part is in the shape of a triangle whose vertices are two arbitrary points on a side of the grid section and an arbitrary point inside the grid section, or a quadrangle whose vertices are a crossing of grid lines, an arbitrary point near a straight line connecting crossings of grid lines in the diagonal positions, and two arbitrary points on sides of the grid section. An ion generating element is formed which can generate positive ions and negative ions. The ion generator can be used in an air conditioning apparatus, cleaner or refrigerator.

A switching transformer applies an alternating high voltage across an internal electrode and an external electrode which face each other with a glass tube as a dielectric body between them. The anode side of a diode is connected to the external electrode which is not a voltage supply side electrode, while the cathode side is grounded. When a relay connected to both the terminals of the diode is turned on, substantially equal amounts of positive ions and negative ions are generated, and a bacteria removal/disinfection effect can be obtained by emitting these positive ions and negative ions into the air. When the relay is turned off, a relatively small amount of positive ions and a relatively large amount of negative ions are generated, and a relaxation effect given by negative ions can be obtained by emitting these positive ions and negative ions into the air.

Air refining device and ion generator used for the device

A single-unit air conditioner has a housing and a cooler/heater unit housed in it. The cooler/heater unit can be put into and taken out of the housing with the housing kept connected to an air conditioning duct. Of the four panels forming the four side faces of the housing, three other than the one facing a wall can be removed individually from the housing. The cooler/heater unit has an indoor heat exchanger unit including an indoor blower, which is housed in a fan casing having an outflow opening that can be widened by removing a member so that the outflow opening can be used as an opening through which to maintain a fan. The indoor heat exchanger unit includes heating means for heating, which can be fitted and removed through either of the left-hand and right-hand side faces of the housing. Inside the housing are provided an indoor air passage and an outdoor air passage, of which at least part is partitioned by a partitioning member. The partitioning member has a portion thereof formed into a curved-surface portion, which guides the wind passing through one of the indoor and outdoor air passages.
