Description

  The present invention relates to an air conditioner that controls the operation by detecting the presence or absence of a person using a human body detection device.

  Conventionally, this type of air conditioner uses a human body detection device provided in an indoor unit to detect where a person is in the room and uses the detection information to perform comfortable and efficient air conditioning. Has been proposed (see, for example, Patent Document 1).

  In addition, in this configuration, the human body detection device is exposed to the outside, and as a configuration for concealing it, an air conditioner that improves the appearance by arranging a cover that covers the human body detection device on the front surface of the indoor unit front panel. Generally known.

  3 (a) is a front view of an indoor unit of a conventional air conditioner, (b) is a front view when a cover that covers the human body detection device is removed, (c) is a side view, and FIG. FIG. 5 is an exploded perspective view of a conventional human body detection device unit, and FIG. 5 is a sectional view of the conventional human body detection device unit. As shown in FIG. 1, the indoor unit 6 has a front panel 8 provided with a human body detection device unit 7. The indoor unit 6 determines the blowing direction by specifying the human body position based on the human body position detection information from the human body detection device unit 7 and performs air conditioning.

As shown in FIGS. 4 and 5, the human body detection device unit 6 includes a human body detection device 1, a human body detection device fixing base 8, a reinforcing plate 3, and a cover 2, and the human body detection device 1 is included in each element. A plurality of corresponding lenses 4 are provided, and the reinforcing plate 3 is disposed on the human body detecting device 1 and the plurality of lenses 4 included in the human body detecting device 1, and the cover 2 is disposed on the reinforcing plate 3.

  However, in the conventional configuration, the human body detection device has a configuration in which a spherical lens is fixed in a one-to-one relationship corresponding to each element, so that this lens is exposed to the outside as it is. As a result, the detection accuracy and appearance quality due to dust and the like may be deteriorated.

  In the method of arranging the cover in front of the human body detection device, the thickness of the cover must be as thin as possible (for example, 0.5 mm or less in the case of a cover made of high-density PE) in consideration of the infrared loss rate. In this case, the reinforcing plate is joined from the back side of the cover to prevent the appearance from being deteriorated due to insufficient strength and surface undulations. However, an internal space for the reinforcing plate is required, and the human body detector unit is located in front of the front panel. (In the above example, 10 mm or more).

  The present invention solves the above-described conventional problems, and does not deteriorate the infrared loss rate, and has a thickness of a cover having a strength that does not require a reinforcing plate, and is an air conditioner that prevents deterioration in detection accuracy and appearance quality. The purpose is to provide a machine.

In order to solve the above-described conventional problems, the air conditioner of the present invention has a cover that covers the entire human body detection device, and the cover is made into a lens, thereby deteriorating the infrared loss rate of the spherical lens on the human body detection device. Accordingly, it is possible to provide an air conditioner that has a thickness of a cover that is unnecessary and does not require a reinforcing plate, and prevents deterioration in detection accuracy and appearance quality.

  The air conditioner of the present invention has a cover thickness that does not require a reinforcing plate without deteriorating the infrared loss rate, prevents deterioration of appearance quality such as detection accuracy and undulation, and does not require a spherical lens By doing so, the number of parts and assembly costs can be reduced, so that a high-performance air conditioner can be provided at low cost.

  A first aspect of the present invention is an air conditioner that controls the operation by detecting the presence and position of a person in a room using a human body detecting device, and a cover that covers the entire human body detecting device is disposed, and the cover is formed into a lens. By reducing the loss rate of infrared rays, the thickness of the cover has a strength that does not require a reinforcing plate, prevents deterioration of appearance quality such as detection accuracy and undulation, and eliminates the need for a spherical lens. Since the number of parts and assembly cost can be reduced, a high-performance air conditioner can be provided at low cost.

  In the second invention, in particular, by forming a lens by forming an aspherical lens divided into sections in the cover of the first invention, the strength that does not require a reinforcing plate without deteriorating the infrared loss rate is obtained. By providing a thick cover, preventing deterioration of appearance quality such as detection accuracy and undulation, and eliminating the need for spherical lenses, the number of parts and assembly costs can be reduced, providing a high-performance air conditioner at a low price. can do.

  In the third invention, in particular, the performance of the first or second invention is improved by the configuration corresponding to the set of aspherical lenses integrated with at least one human body detection device. The internal space can be shortened while maintaining.

  In the fourth aspect of the invention, in particular, the human body detection device according to any one of the first to third aspects is driven left and right, so that a wide range can be detected even if the number of human body detection devices is small. .

  In the fifth aspect of the invention, in particular, the human body detection device according to any one of the first to fourth aspects is driven up and down, so that a wide range can be detected even if the number of human body detection devices is small. .

  In the sixth aspect of the invention, in particular, the human body detecting device is attached to the cover of any one of the first to fifth aspects of the invention, so that the human body detecting device unit can be handled as a unit, reducing assembly man-hours and serviceability. Can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
