Description

  The present invention relates to an air conditioner provided with an ion generator.

  In general, negative ions are said to have an effect of relaxing a person, and generation of positive ions and negative ions is said to have an effect of suppressing mold and the like.

  Japanese Unexamined Patent Application Publication No. 2002-216933 discloses an air conditioner including an ion generator that can be switched between an operation that mainly generates negative ions and an operation that generates positive ions and negative ions.

  However, the air conditioner equipped with the ion generator disclosed in Japanese Patent Application Laid-Open No. 2002-216933 is switched between an operation that mainly generates negative ions depending on the presence of a person and an operation that generates approximately the same number of positive ions and negative ions. In addition, the amount of ion generation is adjusted to a fixed amount regardless of the presence or absence of a person.

Since the air volume is constant regardless of the presence or absence of people, in a space where people stay only for a short time, such as a toilet, even if they try to relax people by generating negative ions, before the negative ions reach the toilet However, if a person leaves the room, or if the air volume is increased, the sound of the fan will reverberate when quiet, such as at night.

  The present invention can relax a human body by spreading negative ions in the room at an early stage when a human body is detected in the room, and can suppress mold and the like in the room with a silent sound when no human body is detected. An object is to provide an adjusting device.

  An air conditioner according to the present invention includes: an ion generator that generates ions; a blower that blows air containing ions generated by the ion generator into a room; a human body sensor that detects a human body in the room; And a controller for controlling the ion generator and the blower based on the detection signal of the human body sensor. The controller mainly generates negative ions and increases the air flow rate when a human body is detected in the room. It is a manned operation mode in which the air volume is set, and when no human body is detected in the room, an unmanned operation mode in which positive ions and negative ions are generated and the air flow rate is reduced.

  According to such an air conditioning apparatus of the present invention, when a human body is detected in the room, negative ions are mainly generated and the air flow rate is increased, so that the negative ions can be spread throughout the room at an early stage to relax the human body. When a human body is not detected in the room, approximately the same number of positive ions and negative ions are generated and the amount of air flow is reduced, so that indoor mold and the like can be suppressed silently.

  The controller of the present invention may be configured to be able to set a forced operation mode as the unattended operation mode regardless of whether a human body is detected in the room. In this way, an operation that sufficiently suppresses the occurrence of mold or the like can be executed.

  According to the air conditioner of the present invention, when a human body is detected in the room, negative ions can be spread in the room at an early stage to relax the human body. can do.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an internal perspective view of the air conditioner according to the embodiment, FIG. 2 is a timing chart showing the operation contents of the air conditioner of FIG. 1, and FIG. 3 is a block diagram of the air conditioner of FIG.

  As shown in FIG. 1, the air conditioning apparatus 1 includes a casing 2, a blower 4 and an ion generator 6 disposed in the casing 2. The air conditioner 1 is installed on a wall surface in the room.

  An ion blower outlet 8 for releasing ions generated from the ion generator 6 is provided at the lower part of the casing 2, and an air inlet (not shown) is provided at a portion facing the center of the blower 4 on the back of the casing 2. Is provided.

  The blower 4 is arranged on the upper back surface in the casing 2, and the ion generator 6 is arranged in a position between the blower 4 and the ion outlet 8 in the casing 2.

  The air conditioner 1 according to the present embodiment is an AC high voltage method in which an induction electrode and a discharge electrode are arranged to face each other through a ceramic dielectric, and an AC voltage is applied between the electrodes to cause discharge to generate ions. However, the present invention is not limited to this, and various known methods such as a direct current high voltage method and a method of generating ions using radiation or ultraviolet rays can be used.

  Although not shown in FIG. 1, a human body detection sensor 10 (see FIG. 3) that detects the presence or absence of a human body on the front surface of the casing 2 and a mode changeover switch 12 that switches the operation mode of the air conditioner (see FIG. 1). 3) and a controller 14 is provided inside the casing 2. The controller 14 is configured to receive a detection signal from the detection sensor 10 and a signal from the mode switch 12 and transmit a control signal to the ion generator 6 and the blower 4.

  As the human body detection sensor 10, various sensors that can detect a human body in the room, such as an infrared sensor, an ultrasonic sensor, a single wave microwave sensor, and a dual frequency microwave sensor, can be used.

  The operation method of the air conditioner 1 having such a configuration will be described below with reference to FIG. In FIG. 2, when there is no human body in the room, the human body detection sensor 10 does not detect the human body, the air volume of the blower 4 becomes a small air volume, and the ion generator 6 generates approximately the same number of positive ions and negative ions. It becomes a mode. On the other hand, when a human body enters the room, the human body detection sensor 10 detects the human body, the air flow of the blower 4 becomes a large air volume, and the ion generator 6 is in a manned operation mode in which negative ions are mainly generated. When the human body leaves the room, the human body detection sensor 10 does not detect the human body, so that the air volume of the blower 4 again becomes a small air volume and the ion generator 6 generates an approximately the same number of positive ions and negative ions. Become.

  Regardless of whether a human body is present in the room, the operation mode of the air conditioner 1 can be forcibly switched to the unattended operation mode by pressing the mode switch 12. When the mode changeover switch 12 is pressed once again, the operation mode returns to the automatic operation mode in which the manned operation mode or the unmanned operation mode is automatically executed based on the detection signal of the human body detection sensor 10.

  According to the air conditioner according to the present embodiment, when a human body is detected in the room, the operation mode is automatically set to the manned time mode, the ion generator 6 mainly generates negative ions, and the blower 4 sets the air flow rate to a large air volume. Therefore, it is possible to relax the human body by spreading negative ions in the room at an early stage. Further, when the human body is not detected in the room, it automatically enters the unattended operation mode, and the ion generator 6 generates approximately the same number of positive ions and negative ions and the blower 4 reduces the amount of air blown. Mold and the like can be suppressed.

  In this embodiment, the mode change switch 12 can forcibly enter the unmanned operation mode, so that mold and the like can be sufficiently suppressed.

  The present invention is not limited to the above embodiment, and may take other forms. For example, the air conditioner may be provided with an intermittent operation function, and the ion generator and the blower may be intermittently operated when a human body is not detected in the room. In this case, no operating noise is generated when the blower is not operated. It is also possible to save energy.
