A heating cooker includes a housing having an exhaust aperture; a top plate on the housing with a heating zone; a heating coil to perform induction heating to heat a heating target on the heating zone; an air-sending device; a cooling air guide having an air outlet, to guide air from the air-sending device to the air outlet; and an exhaust air guide aperture with an air passage extending from a first inlet to a first outlet. The air outlet and the exhaust aperture are aligned with each other and the air outlet of the cooling air guide and the heating coil are aligned each other, both in the front and back direction. The air outlet is arranged on a front side relative to a center of the heating coil. The air passage of the exhaust air guide has a longer length than the first outlet of the air passage.

An air blowing device and an air blowing system reduces a region where a person cannot be recognized in a space provided with the air blower, and achieves control of the air blower in view of a person in a larger range in the space. The air blower includes: a first sensor configured to detect a position of a human in a first human detection range; a receiver configured to receive a detection result of a second sensor transmitted from a transmitter of a sensor-mounted device, the sensor-mounted device including the second sensor configured to detect a position of a human in a second human detection range; and a controller configured to perform air blowing control when the first sensor does not detect a human in the first human detection range and the second sensor detects a human in the second human detection range.

Air blower and air blowing system

An air purifying operation is performed with a consideration for an influence of a purifying material on a person, and user's comfort and efficiency of the air purifying operation are both achieved. An air purifier includes a casing, an inlet, outlets, blowers, a decontamination unit, air ducts, movable louvers, a horizontal rotation mechanism, an ozone generation mechanism, human detection means, a control unit, or the like. The control unit detects whether or not there is a person in a room by the human detection means. Then, the control unit controls at least one of parameters including an ozone generation amount, a wind direction, an amount, and a speed of blown-out air based on the human detection result. Thus, if there is a person in the room, for example, a human avoiding operation, a human area operation, or the like can be performed. If there is no person, an indoor air purifying operation for uniformly purifying air throughout the room can be performed.

An air conditioning system includes: an air conditioning device, a ventilator, a sensor group, an operation terminal, and a control device installed in a building. The control device performs controlling and monitoring of operation of the air conditioning device and the ventilator. The control device controls the ventilator so as to operate during the maintenance operation of the air conditioning device.

Air-conditioning system, controller, and program

An air purifier capable of reducing time required for purification of a room without giving a feeling of discomfort to a human in the room is provided. During operation of an air purifier, air drawn from an inletinto a casingis purified by a purification deviceand the air is blown to the outside from an outlet. If a user of the air purifierselects a particular operation mode in which the user designates an air volume, a control deviceperforms air volume maintaining control. In the air volume maintaining control, with a volume of air blown out from the outletby the air blowing devicemaintained constant, a speed of the air is varied by an air guiding devicebased on a status of pollutant detection. Alternatively, the speed of the air is varied by the air guiding deviceand the volume of the air is varied by the air blowing device. Consequently, a dust removal efficiency can be enhanced without giving a feeling of being blown by air to a human in a room, enabling reduction of time required for purification of the room while maintaining user comfort.

A deodorizer includes: a body case having an inlet and an outlet opening outward and having an air duct that provides communication between the inlet and the outlet; a blowing fan included in the body case, for introducing indoor air into the air duct extending from the inlet to the outlet; deodorizing means provided in a middle of the air duct, through which the introduced air can pass; heating means placed to face at least a partial region of the deodorizing means, for heating the deodorizing means at 200&#xb0; C. or less; and a controller for controlling operations of the blowing fan and the heating means. The deodorizing means includes, on a carrier, an adsorbent that does not oxidatively decompose an adsorbed material, a catalyst component that oxidatively decomposes the adsorbed material, and a rate of conversion of alcohol into acetic acid by the catalyst component is 15% or less on average across the entire deodorizing means.

A cyclone separation device includes: a swirl chamber that swirls air containing dust along a side wall therein, and separates dust from the air containing dust; a first dust collection chamber that communicates with an inside of the swirl chamber through a first opening formed in the side wall of the swirl chamber; a second dust collection chamber that communicates with the inside of the swirl chamber through a second opening formed on a downstream side of the first opening in the swirl chamber; a discharge pipe that communicates with a discharge port for discharging air in the swirl chamber; and a plurality of inlets that are provided on an upstream side of the first opening, and through which the air containing dust flows into the swirl chamber.

Cyclone separation device and electric vacuum cleaner with same

A cyclonic separator and a vacuum cleaner which efficiently separates dust, collect the dust without re-scattering it and make low noise are provided. In a primary cyclone portion, a primary swirl chamberswirls air containing dust sucked from a primary inlet, and thereby, separates a first dust and a second dust from the air containing dust to collect them respectively in a zero-order dust casewhich is provided at a side of the primary swirl chamberand communicates with a zero-order opening portionprovided at a side wall, and a primary dust caseprovided at a lower side of the primary swirl chamber. In a secondary cyclone portion, a secondary inletwith an opening area smaller than that of a primary outlet bodysucks air exhausted from the primary outlet body, a secondary swirl chamberswirls the first air to separate the second dust which is finer than the first dust from the first air to collect the second dust in a secondary dust caseprovided at a lower side of the secondary swirl chamber. With regard to the cyclonic separator with such a configuration, the zero-order dust caseis formed to cover at least a part of the secondary cyclone portion

Cyclone separator and vacuum cleaner

A vacuum cleaner including a suction port body, a motor-driven blower, and a cyclone part that is disposed between the suction port body and the motor-driven blower and is provided with an inflow port, a swirl chamber, and a discharge port body. The side surface of the discharge port body is composed of a cylindrical mesh and a conical mesh. The side wall of the swirl chamber is composed of a cylindrical part and a conical part. The vacuum cleaner further includes a zero-order opening formed by opening a part of the cylindrical part, a first-order opening formed by opening a part of the conical part, a zero-order dust case communicating with the swirl chamber via the zero-order opening, and a first-order dust case communicating with the swirl chamber via the first-order opening.
