(Embodiment 1)
1 and 2 are diagrams showing an example of the configuration of the air purifier according to the embodiment of the present invention. In FIG. 1, the air purifier main body is provided with an intake port 3 for sucking in indoor air and a discharge port 2 for blowing out air, and the display unit and operation unit 1 for displaying ON / OFF of the air purifier, air flow adjustment and operation state, and odor. An odor sensor ventilation path 4 that allows air to pass through the odor sensor that is a detection means and a dust sensor ventilation path 5 that allows air to pass through the dust sensor that is a substance detection means that causes allergies are provided. Further, as shown in FIG. 2, a fan 6 that allows the intake port 3 and the discharge port 2 to communicate with each other inside the main body, and a dust collection filter 8 and a deodorizing unit as an air purifier that cleans the air sucked from the intake port 3. A filter 12 is provided, and a deodorizing and sterilizing unit 9 is provided in the vicinity of the discharge port 2. The deodorizing and sterilizing device 9 performs deodorization and sterilization by discharging charged fine water droplets into the air. In order to grasp the state of the air from the outside, a odor sensor 10 as a odor detection means and a dust sensor 11 as a substance detection means for causing allergies are provided at the lower part of the display unit and the operation unit 1, and the opening and closing of the window and the season Is provided with a temperature sensor 13 and an atmospheric pressure sensor 14, and the operation is controlled using these detection means.

  Moreover, the season determination means of the present invention is configured to provide a temperature sensor 13 as temperature detection means in the air cleaner main body, and to determine the season based on the initial value of the temperature.

  Further, the opening / closing detection means of the present invention is provided with a temperature sensor 13 and an atmospheric pressure sensor 14 in the air purifier main body, and storage means for storing these initial values, and further comprises the above-described season determination means. .

  In the above configuration, the determination means in the season determination means will be described with reference to a flowchart. A temperature sensor 13 composed of a thermistor detects an initial temperature at which power is supplied to the air purifier by a user turning on an engine key or the like. If the temperature at this time is 28 ° C. or higher, which is the temperature at which people begin to feel hot, it is determined that summer. Further, when the temperature is 28 ° C. or lower, it is determined to be winter if it is 10 ° C. or lower, and to spring or autumn otherwise. This means makes it possible to drive according to the season.

  Next, window opening / closing detection means will be described with reference to the flowchart of FIG. After measuring the initial temperature and the initial atmospheric pressure, the temperature is measured as needed. If the room temperature decreases by 4 ° C. or more, it is determined that the window is opened if the season is other than summer. This operation is performed in order to decrease when the window is opened because the interior temperature of the vehicle is lower than the outdoor temperature in seasons other than summer. If the season is summer, the atmospheric pressure is measured. If there is no atmospheric pressure change, the room temperature is changed by attaching an air conditioner. If the atmospheric pressure decreases, the window is opened. This operation is performed to determine whether the temperature has dropped because the window is opened or closed or because the air conditioner is installed. Compared to using an air conditioner, the vehicle is warmed and expanded when the window is opened. Utilizes the fact that air pressure drops because the air goes outside. Furthermore, if the temperature rises outside the summer after opening the window, it is determined that the window has been closed.If the temperature has decreased again in the summer, it is determined that the window has been shut down to turn on the air conditioner. Can be detected.

  The operation of the air cleaner of the present invention will be described with reference to the flowchart of FIG. After the power is turned on, the season is determined by the season determination means. After that, when it is determined that the window is closed by detecting the opening / closing of the window, the deodorizing and disinfecting apparatus 9 that performs deodorizing and disinfecting that is a deodorizing means and a disinfecting means is periodically used in summer when the season is determined. For example, it is operated once per minute. By performing this operation, germs and odors that are generated at high temperatures in summer can always be removed. In seasons other than summer, the process is executed only when the odor sensor 10 reacts. This operation enables energy-saving operation. In particular, electricity consumption during the dry season in winter can be suppressed. Further, when the window is opened, the operation of the odor sensor 10 which is an odor detection means and the deodorization / sterilization apparatus 9 for performing deodorization / sterilization are stopped. This operation is for energy-saving and efficient air purification in the vehicle where air is constantly switched. Deodorizing and sterilizing is not limited to detecting odor when the window is open. Can be prevented from leaking to the outside and reducing the efficiency of deodorization and sterilization in the vehicle. In addition, when the dust sensor 11, which is a substance means that causes allergies, detects a substance that causes allergies when the window is opened, the user is informed that the area where there are many substances that cause allergies is present And the operation unit 1 By this operation, the user can immediately close the window to inform the user that he / she is traveling in a place where there are many substances that cause allergies.

(Embodiment 2)
In the present embodiment, in addition to the first embodiment, a date and clock function is built in an internal memory as a season determination means, thereby making it easy to distinguish between spring and autumn in determining the season. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The season determination means in the present embodiment includes a temperature sensor similar to that of the first embodiment and a storage battery that is equipped with a date and clock function by an internal memory and maintains the clock function.

  In the above configuration, for the determination by the season determination means, as shown in the flowchart of FIG. 6, the temperature sensor is configured with a thermistor as the initial temperature when the power is supplied to the air purifier by the user turning on the engine key, etc. Detect at 13. If the temperature at this time is 28 ° C. or higher, it is determined to be summer. Further, when the temperature is 28 ° C. or lower, if it is 10 ° C. or lower, it is determined to be winter, otherwise it is compared with the date in the internal memory, and if it is between February and May, it is determined to be spring. The operation of the air cleaner of the present invention will be described. As shown in the flowchart of FIG. 7, the season is determined by the season determination means after the power is turned on. Then, when it is determined that the window is closed by detecting the opening and closing of the window, if the season is spring, the fan airflow is maximized. With this operation, pollen that has entered the vehicle can be removed immediately in the spring when there are many substances that cause allergies such as pollen. In this embodiment, in addition to the first embodiment, operation corresponding to spring in which there are many substances causing allergies such as pollen becomes possible.

  The air cleaner according to the present invention can be operated according to the season by using the same means even in an indoor air cleaner or a humidified air cleaner.
