Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a finger-stick prevention device for a thin air conditioner having a structure in which the distance between the blower fan and the air outlet is narrow.

[Prior art]

In the air conditioner, a decorative cover 12 is attached to the front of a rear base 11 to form a housing 13, and a heat exchanger 1 and a blower fan 2 are housed in the housing 13.

The decorative cover 12 has a suction port 14 at the upper front surface and a discharge port 3 at the lower front surface.

The heat exchanger 1 is placed facing the suction port 14, and the blower fan 2 is provided facing the discharge port 3.

As shown in Figure 1, indoor air that has been heat exchanged by a heat exchanger 1 is blown out in the direction of the arrow to air condition the room, but in recent years, as the depth dimension A of air conditioners has become thinner, the dimension between the blower fan 2 and the discharge port 3 has become smaller. In a unit with such a structure, there is a risk that fingers 4 may touch the blower fan 2 from the outside through the outlet 3.

That is, the discharge port 3 is provided with left and right wind direction plates 5 and up and down wind direction plates 6 which are crossed in order to convert the wind direction.
The interval between the left and right wind direction plates 5 is very wide, and if the interval 1) between the upper and lower wind direction plates 6, which requires a certain wide width C, is narrowed, the ventilation resistance will increase and the air volume will decrease, so the interval should be widened to some extent. Must.

In addition, the upper and lower wind direction plates 6 supported at both ends have a button near the center, which causes a bend due to a small force from the outside, so that a finger can easily get stuck in the button.

[Purpose of invention]

The present invention aims to prevent fingers from being inserted into the outlet of such a thin air conditioner in which the distance between the outlet and the fan is short.

[Summary of the idea]

In the present invention, a plurality of small holes 7 are provided on the rotation center axis F of the left and right wind direction plates 5 so that the distance E between the left and right wind direction plates 5 is narrower than the width of a finger, and the diameter of the small holes 7 is matched. This is a device for preventing fingers from being inserted into an air conditioner, in which a wire 8 is passed through in the left-right direction and both ends of the wire 8 are fixed.

[Example of idea]

An embodiment of the present invention will be explained with reference to FIGS. 4 and 5.

A small hole 7 is provided on the rotation center axis F of the left and right wind direction plates 5 provided at equal intervals, and a wire 8 is weighed in the small hole 7 so that the distance E between the discharge ports is narrower than the width of a finger. It has a structure that is fixed to the frame 10 of.

This finger insertion prevention structure is characterized in that since the wire 8 is supported by a large number of left and right wind direction plates 5, the amount of deflection is small when a finger is inserted from the outside, and the penetration position is the rotation center of the left and right wind direction plates 5. Since it is on the axis F, rotation of the left and right wind direction plates 5 cannot be prevented.

Further, in a structure in which the upper and lower wind direction plates are fitted together as shown in FIG. 6, the number of wires 8 can be reduced because the upper and lower wind direction plates 6 are supported by the left and right wind direction plates 5.

Furthermore, if the small holes 7 are made into a dish shape as shown in FIG. 7, the rotation of the left and right wind direction plates 5 will be smoother, and the rotational impact caused by the wires 8 will be eliminated.

[Effect of idea]

According to the present invention, it is possible to provide a finger insertion prevention device in which the upper and lower wind direction plates 6 and the wires 8 prevent fingers from being inserted.
