Description

  The present invention relates to an electrical component storage box of an air conditioner.

A conventional electrical component storage box of an air conditioner will be described with reference to FIGS. In order to cope with an abnormality in the electronic control board 2 which is disposed inside the electrical component storage box 1 and has a function of controlling the operation of the electrical components, and the terminal block 3 which is connected by inserting a connecting wire from the outdoor unit from below. The electrical component storage box 1 and the terminal block cover 4 are shaped with a flame retardant resin. The whole of the electronic control board 2 on the component mounting side is covered with a cover 12 made of a flame-retardant resin or an incombustible material of an iron plate (for example, see Patent Document 1).
JP 2001-65913 A

  However, in the conventional configuration described above, a part molded with a flame-retardant synthetic resin is used in order to prevent an abnormality at a part where a constant high voltage may occur due to tracking, part deterioration, small animal approach, or the like. However, in recent years, only a cover using a flame-retardant synthetic resin has a problem of causing anxiety to consumers due to deformation and other problems of the flame-retardant synthetic resin.

  The present invention solves such a conventional problem, and an object thereof is to provide a safe electrical equipment storage box for an air conditioner.

  In order to solve the above-described conventional problems, the electrical component storage box of the air conditioner of the present invention includes a control board having a function of controlling the operation of the electrical components, and a terminal block to which a connection wire from the outdoor unit is connected. In the electrical component storage box having the terminal block cover, the terminal block cover that covers the connecting wire insertion portion of the terminal block is attached to the grill, and the non-combustible material is disposed only in a portion where the terminal block connecting portion can be covered.

  According to the electrical equipment storage box of the air conditioner of the present invention, there is no increase in the construction time in the installation work of the air conditioner, the abnormality of the terminal block caused by the failure of the wire connection construction is blocked by the non-combustible material, and the flame retardancy The deformation of the synthetic resin can be prevented.

  A first aspect of the present invention is a separation-type indoor unit configured by connecting an indoor unit and an outdoor unit by a connection pipe and a connection electric wire, a control board for controlling the operation of the electrical components of the air conditioner, and the control board In the electrical component storage box having a terminal plate that is connected to the outdoor unit and inserted from below, the terminal plate cover that covers the connection wire insertion portion of the terminal plate is attached to the grill, An incombustible material is disposed on the side opposite to the surface.

  Thereby, the abnormality of a terminal block can be interrupted | blocked with a nonflammable material, and a deformation | transformation etc. of a flame-retardant synthetic resin can be prevented.

  The second invention is particularly abnormal in the first invention when constant high power is generated, such as the high power generating parts of the electronic control board during operation and stop, the connecting part of the fan motor, the connecting part of the power cord, etc. An electrical component cover made of a non-combustible material is disposed only in a portion opposite to a portion where there is a possibility of occurrence of the non-combustible material.

  As a result, it is possible to realize a safe electrical component storage box while presenting the noncombustible material only in the necessary part and reducing the volume ratio of the noncombustible material while maintaining the convenience and ease of processing by the flammable synthetic resin. .

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

(Embodiment 1)
FIG. 1 is a front view of an indoor unit of an air conditioner according to the first embodiment of the present invention. FIG. 2 is a perspective view of the indoor unit of the air conditioner according to the present embodiment in a state where the panel and the electrical component cover are opened when connecting the connection electric wires from the outside. FIG. 3 is an exploded perspective view of the electrical component cover. FIG. 4 is a perspective view of the indoor unit of the air conditioner according to the present embodiment in a state where the connection electric wires are fixed.

  In the following, the same components as those in FIGS. 6 and 7 of the prior art are denoted by the same reference numerals, and description thereof is omitted.

  About the electrical equipment storage box of the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, FIG. 1 shows an indoor unit 9, which has a front side exterior with a panel 7. In FIG. 2, when connecting the connecting wire 5 connecting the room and the outdoors to the indoor unit, the connecting wire is inserted from the rear of the bottom frame 6.

  The panel 7 is opened, and a terminal block cover 4 having a cylindrical protrusion on the left and right is mounted on the upper part of the opening of the grille 8 and a hole shape is mounted on the cylindrical protrusion.

  In FIG. 3, the non-combustible material cover 10 made of iron plate has a protrusion 4 a of the terminal block cover 4 and a hole 10 b of the non-combustible material cover 10 at a position facing the terminal block 3 of the terminal block cover 4 made of flame-retardant synthetic resin. It has been installed.

  In FIG. 4, the connecting wire 5 is inserted into the hole of the terminal block 3 and fixed by the wire retainer 11 to complete the connection between the outdoor and indoor wires, and the terminal block 3 is returned to its original state. Can be covered with a non-combustible cover 10.
