Description

This invention relates to an air control system. In large rooms or rooms with complex layouts such as an L-shape, it is difficult for the conditioned air from the air conditioner to efficiently reach every corner of the room, resulting in temperature unevenness. To address this, methods such as using an air conditioner in conjunction with a circulating fan to stir the air within the room and reduce temperature unevenness have been devised. For example, Patent Document 1 discloses a circulator capable of operation start control independent of room temperature. This circulator comprises a fan that creates airflow in a target space and a control unit that controls the fan's operation. In this circulator, designed to reduce temperature unevenness in a target space, it includes a humidity sensor that detects the humidity of the air in the target space. The circulator starts operating when a change in humidity within a predetermined range occurs within a predetermined time period. Japanese Patent Publication No. 2009-210223 A functional block diagram of the air control system according to the first embodiment of the present invention.A perspective view of an air conditioning device in the first embodiment of the air control system according to the present invention.A diagram showing the positional relationship between a range hood and air conditioning equipment in an indoor space including the air control system of the first embodiment of the present invention, (A) in the case of an indoor space with a rectangular base, and (B) in the case of an indoor space with an L-shaped base.A flowchart for controlling the air control system according to the first embodiment of the present invention (modified example 1).A flowchart for controlling the air control system according to the first embodiment of the present invention (modified example 2).A flowchart for controlling the air control system according to the first embodiment of the present invention (modified example 3).A flowchart for controlling the air control system according to the first embodiment of the present invention (modified example 4). In the following sections, various embodiments of the present invention will be described with reference to the drawings. <First Example> Referring to Figures 1 to 7, the air control system 100 in this embodiment will be described. As shown in Figure 1, the air control system 100 comprises a range hood 10, an air conditioning unit 20, and a control unit 30 that controls the range hood 10 and the air conditioning unit 20 to work in conjunction. The range hood 10 is placed near a stove installed in a kitchen or the like for cooking, and is a device that sucks in oil fumes and other contaminants generated by cooking along with the indoor air from the hood section, removing oil fumes and other contaminants from the indoor air. The range hood 10 has an exhaust function 13 that exhausts the air drawn in from the hood section to the outside, and a circulation function 14 that returns the drawn-in air to the inside after oil fumes and other contaminants have been removed by a filter or the like. Furthermore, the range hood 10 has a first sensor 11 for detecting indoor air conditions. The first sensor 11 may be installed near the range hood 10. Here, indoor air conditions refer to the air temperature in a location near the stove but unaffected by the stove's heat source, and may also include air humidity, or only air humidity. Therefore, the first sensor 11 is a known sensor for measuring air temperature and humidity. Furthermore, the range hood 10 has a determination unit 12 that determines whether or not cooking is being performed near the stove. The determination unit 12 may be located near the range hood 10. The determination unit 12 may, for example, determine that cooking is being performed by receiving a signal from the stove indicating that a heat source is being used, or it may determine that cooking is being performed on the stove using an infrared sensor, an oil smoke sensor, a camera that images the top surface of the stove, etc. Furthermore, it is preferable that the determination unit 12 determines the exhaust airflow of the exhaust function 13 according to the cooking state. Here, "cooking state" refers to various cooking conditions, such as stir-frying over high heat, boiling water, or simmering over low heat. Generally, it is known that the exhaust airflow of the range hood 10 is changed to "high," "medium," or "low" depending on these various cooking states, to achieve the appropriate exhaust airflow. The determination unit 12, for example, uses an infrared sensor to determine the appropriate exhaust airflow for a cooking state such as stir-frying over high heat, setting the exhaust airflow to "high." It also determines whether the determined exhaust airflow matches the current exhaust airflow. The air conditioning unit 20 is a device primarily used for air conditioning purposes, such as being placed in living roo
