Description

  The present invention relates to an indoor unit having a negative ion generator in an air conditioner composed of an outdoor unit and an indoor unit.

  A conventional indoor unit of an air conditioner accommodates a blower and a heat exchanger in a unit body, sucks indoor air into the unit body by operation of the blower, passes the heat exchanger, and exchanges heat. It blows out into the room from the blowout opening.

  In recent years, in addition to such a heat exchanging effect on indoor air, an indoor unit equipped with a function of removing impurities such as dust contained in the indoor air and cleaning it as an additional function has been provided.

  The above-mentioned additional functions have been pointed out that very fine dust is contained in the indoor air, which may cause hay fever and allergies. The purpose is to supply clean air through the removal of dust in the air.

  An air conditioner incorporating a negative ion generator for the above problem is disclosed, and negative ions are supplied directly into a living room or with heat-exchanged air. It is known that the supplied negative ions are absorbed by the human body to activate cellular tissues, promote waste discharge, and improve metabolism (see, for example, Patent Documents 1 and 2).

Also, in an indoor unit of an air conditioner that blows out indoors through an indoor blower, it is disposed on the air suction side of the indoor heat exchanger, and removes impurities such as dust from the indoor air sucked into the unit body and cleans it. There is an indoor unit including an electric dust collector, which is an air cleaner to be converted, and a negative ion generator that is disposed in a blow-off air passage of the indoor blower and generates negative ions and supplies the negative ions to the room (for example, Patent Document 3). reference).

  However, in the above conventional example, the negative ion generator is intended to be disposed in the air passage in the indoor unit of the air conditioner including the air blower and the heat exchanger, but the negative ion generator is mounted in the air blowing circuit. In this case, the indoor unit housing near the negative ion generator and the wall surface on which the indoor unit is installed are charged, so that dust is attracted and adhered to the indoor unit housing and the nearby wall surface. It had the problem of soiling nearby walls.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide an air conditioner that suppresses charging in the vicinity of a negative ion generator and prevents adhesion of dust.

In order to solve the above-described conventional problems, an indoor unit of an air conditioner according to the present invention is an indoor unit of an air conditioner provided with a blower, a heat exchanger, and a negative ion generator, and the negative ion generator is a blowout of the indoor unit. It is provided at the center of the air passage, and a conductor is provided in the vicinity of the negative ion generator, and the conductor is installed on the back surface of the base frame constituting the housing of the indoor unit and at a position where it cannot be seen from the outside. It is what.

As a result, even if the negative ion generator or the indoor unit housing is charged, it is discharged from the conductor provided in the vicinity of the indoor unit housing, so that dust is not sucked into the indoor unit housing. As a result, the indoor unit housing and the wall on which the indoor unit is installed can be prevented from adhering to dust, and since the conductor is in a place where it cannot be seen from the outside, charging is prevented without impairing the appearance of the indoor unit. , Dirt due to dust can be prevented.

According to a second aspect of the present invention, the conductor is electrically connected to the ground of the indoor unit.

  As a result, the charging of the indoor unit housing can be efficiently discharged, and dust can be prevented from adhering to the my indoor unit housing and the wall surface.

  According to the present invention, it is possible to prevent contamination due to adhesion of dust by preventing charging of the indoor unit housing and the wall surface to be installed due to the provision of the negative ion generator.

An indoor unit of an air conditioner according to a first aspect of the present invention is an indoor unit of an air conditioner provided with a blower, a heat exchanger, and a negative ion generator, and the negative ion generator is provided at the center of the blowout air passage of the indoor unit. The conductor is provided in the vicinity of the negative ion generator, and the conductor is installed on the back surface of the frame constituting the housing of the indoor unit and at a position where it cannot be seen from the outside. As a result, even if the negative ion generator or the indoor unit casing is charged, it is discharged from the conductor provided in the vicinity of the indoor unit casing, so that dust is not attracted to the indoor unit casing. As a result, the indoor unit housing and the wall on which the indoor unit is installed can be prevented from adhering to dust, and since the conductor is in a place where it cannot be seen from the outside, charging is prevented without impairing the appearance of the indoor unit. , Dirt due to dust can be prevented.

The indoor unit of the air conditioner according to the second aspect of the invention is particularly effective in the first aspect of the invention in that the electrical conductor is electrically connected to the ground of the indoor unit to efficiently discharge the negative ion generator. The structure which prevents electrification is enabled.

  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.

(Embodiment 1)
FIG. 1 is a perspective view of an indoor unit of an air conditioner according to the first embodiment of the present invention.

  In FIG. 1, 1 is a negative ion generator, 2 is a conductor, 3 is a front frame (left), 4 is a front frame (right), 5 is a front panel, and 6 is a underframe. Although not shown, an air blower and a heat exchanger are arranged inside the air conditioner.

  By disposing the conductor 2 in the vicinity of the negative ion generator 1, charging can be suppressed and dust can be prevented from adhering to the frame 6 or the wall surface on which the air conditioner is installed.

  This is because, even if the negative ion generator 1 or the frame 6 constituting the indoor unit housing is charged, for example, the electric conductor 2 provided in the vicinity of the frame 6 is discharged, so that dust is sucked into the indoor unit housing. Absent. As a result, the wall on which the indoor unit housing and the indoor unit are installed can prevent dust from adhering.
