Abstract: An electronic dust collector has a discharge line spaced parallel to a dust collector electrode. Discharge line fixing parts at the ends of the discharge line are bent outward to increase the distance from the dust collector electrode, thereby reducing the likelihood of abnormal discharge between the discharge line fixing parts and the dust collector electrode. In another embodiment, the discharge line and the discharge line fixing parts remain in alignment, and the ends of the dust collector electrode facing the line fixing parts are bent outward. The electronic dust collector may be part of an air conditioner. The dust collector electrode has a heater therein for self cleaning.

Abstract: A dust collection electrode with catalyst to be provided on the electronic dust collector is manufactured simply at low cost without using a furnace. To the surface of the metal tube of the sheathed heater a low temperature curing type heat resistant inorganic adhesive is applied. Thereafter, a catalyst such as Zeolite is adhered to the heat-resistant inorganic adhesive. Next, the sheathed heater is energized to make self-heating, and using said heating, the heat-resistant inorganic adhesive is heated to cure, thereby fixing the layer to the surface of the metal tube.

Abstract: An air conditioner which includes therein a dust collecting device having a high voltage unit coupled to a power supply and discharge and dust collecting electrodes each coupled to the high voltage unit, and which has an air cleaning function for collecting by means of the dust collecting device dust contained in external air sucked by rotation of a fan thereby to exhaust the air thus cleaned to an outside. The air conditioner further includes a microcomputer control section (dust removing control section) which executes a dust removing mode for heating a heater provided at the dust collecting electrode to remove dust adhered to the dust collecting electrode, in which the dust removing control section executes the dust removing mode after stopping the operation of the air conditioning function.

Abstract: An air conditioner has an electronic dust collector incorporated in its casing. A mounting plate is grounded which, in turn, grounds the casing of the air conditioner. This reduces adsorption of dust to the casing, thereby preventing soiling of the casing with dust or fine particles.

Abstract: An electronic dust collector for collecting and removing dust from an air stream uses a corona discharge between a discharge electrode and a dust collection electrode to ionize the dust particles which are then attracted to, and held, on the surface of the negatively charged dust collection electrode. The surface of the dust collection electrode includes a catalyst layer for oxidizing and decomposing the deposited dust thereon. A heater is included in the dust collection electrode for periodic self-cleaning. The application of electricity to the heater is controlled to produce slow moderate temperature elevation during the self-cleaning of the dust collection electrode. This permits stepwise oxidation and decomposition of the dust deposited on the dust collection electrode, thereby cleaning the dust collection electrode by removing the dust on the dust collection electrode while suppressing generation of smoke and odor which would otherwise occur by burning of the dust.

Abstract: An air conditioner includes a discharge electrode. The discharge electrode is arranged at a location spaced by a distance between the discharge electrode and a dust collecting electrode or greater. The discharge electrode also is positioned in a main stream of an air flow caused by a cross flow fan. The dust collecting electrode is provided at a location outside the main stream of the air flow and downstream of the discharge electrode relative to a direction of the air flow.

Abstract: An air conditioner includes an electric dust collector arranged between an evaporator and a heat shield plate. This electric dust collector includes a discharge electrode and a dust collecting electrode. The discharge electrode is applied with a positive polarity of high direct current voltage from a high voltage power source, while the dust collecting electrode is supplied with a negative polarity of high direct current voltage. Accordingly, the dust charged through plus electric discharge by the discharge electrode is attracted onto the dust collecting electrode or a casing thereof.

Abstract: In a hand drier for drying the hands by blowing hot wind at the extended hands, a drying time is contracted. Unpleasant feelings are avoided by excessively increasing the hot wind temperature.By perceiving the hands extended to the drying portion 2 with a hand sensor 9, the air is sucked by the fan 7 and the air is heated by the heater 8 to discharge the air to the drying portion 2. The Peltier effect element 6 is arranged in a ventilation passage from the air sucking opening 4 to the discharging opening 3 so that the heat sucking side A may be thermally exchanged for the air within the ventilation passage 5, so as to remove the humidity of the air.

The cooking device (breadmaking device) is provided with a transformation means which transforms a menu number set by a menu set means to the binary digit data having a fixed bit length, and a control data preparation means in which a cord which is able to show the transformed binary digit data by a fixed bit number when the above binary digit data is divided to each fixed bit number, is allowed to correspond to a parameter level of a step control variable, and the above data is read out from the data table which memorizes the data of each step corresponding to the above parameter level based upon the above code and transforms the above read-out data to the control data.

Abstract: In a temperature controlling method of a kitchen-heating apparatus having a temperature sensor at a certain place in the heating area, the temperature control is performed by comparing a temperature detected by the temperature sensor with a set temperature. In this case, an acceleration of the temperature ascent and descent at each certain interval is required and the temperature of the above heating portion is controlled with a duty ratio which corrects the duty ratio of the above heating portion of each interval with the acceleration of the temperature ascent and descent in the front step.
