Description

[Detailed Description of the Invention] <Industrial Application Field> This invention relates to an air conditioner equipped with an electrostatic air purifier.

<Prior Art> As a conventional example of this type of air conditioner, the one shown in Fig. 4 has been proposed.If we explain this based on this conventional example, a slit-shaped slit is formed in the front door 2'. A ventilation path 9' is formed by the opened suction port 3', prefilter 4', electrostatic dust collection unit (hereinafter referred to as dust collection unit) 5', heat exchanger 6', and outlet 7'.
The air conditioner is equipped with a blower fan 8' in the ventilation path 9', and opening/closing fittings 11' are attached to the left and right sides of the upper rear surface of the front door 2' so that the front door 2' can be opened and closed using the upper part of the front door 2' as a fulcrum. It was something I had done.

<Problems to be solved by the invention> In this conventional example, due to the installation condition of the air conditioner, when the front door 2' is opened when the dust collection unit 5 is removed for cleaning, it opens in the forward direction. There were times when the face of the person who was performing the movements became distorted and it was difficult to open the door.

In addition, there were cases where the front door 2' collided with a fluorescent lamp or the like hanging from the ceiling.

<Means for solving the problems> In order to solve the problems of the conventional method, grooves are provided on the inner surface of the left and right panels of the front cover, and a rotating shaft is provided in the center of the front surface, while grooves are provided on the left and right sides of the front cover. A protrusion that slides in the groove is provided, and a guide on the center back surface is provided on which the other end of the rotating shaft slides.

<Operation> When removing the dust collection unit 5 for cleaning, first remove the two screws that secure the front door 2 from the front, then pull the lower part of the front door 2 slightly toward you, and the rotating shaft 12 will be a reinforcing member that supports the air outlet 7. 14 as a fulcrum, and at the same time, the front door 2 begins to lower along the grooves 10 on the left and right sides of the front cover 1 via the protrusions 11 on the left and right sides of the front door 2. When the rotating shaft 12 has rotated about 100 degrees, the front door 2
The front door 2 starts sliding along the groove in the guide 13 and stops when the protrusion 11 collides with the lower end of the groove 10, and the front door 2 is suspended from the front cover 1 by three points: the left and right protrusions 11 and the rotating shaft 12. After that, the dust collection unit 5 fitted into the insulating member 17 can be removed.

When closing the front door 2, it is sufficient to do it in the opposite direction to when opening it.

In this way, since the front door 2 is simply moved downward, it can be opened and closed extremely smoothly, and the person trying to remove it no longer has the trouble of looking at his or her face as in the conventional case. Also, I no longer bump into fluorescent lights hanging in front of the air conditioner.

〈Example〉 To explain an example shown in Fig. 3 from Fig. 1, 1
1 is a front cover that covers the front surface of an indoor unit of an air conditioner, and has a front door 2 in which a suction port 3 is opened in the form of a slit in most of the front surface except for a part on the right side.

On the left and right sides of the front door 2, there are protrusions 11 that slide along the grooves 10 on the inner surfaces of the left and right side plates of the front cover 1, and in the center of the back side there is a guide 13 on which the rotating shaft 12 slides.
is welded, and a pre-filter 4 for removing relatively large dust is inserted on the entire back side along the guide 13 and left and right filter holders 18.

Reference numeral 6 denotes a horizontally long flat heat exchanger located behind the pre-filter 4, and on the side facing the pre-filter 4 there is a thin width part 2 cut out by about 1/2 in the vertical direction and width direction.
A frame-shaped insulating member 1 is formed in the thin width portion 21.
The dust collecting unit 5 is mounted so as not to protrude through the dust collecting unit 7.

The dust collection unit 5 has two on the left and right, and a plurality of plate-shaped discharge counter electrodes connected to a positive power source and a needle-shaped discharge electrode connected to a negative power source are regularly arranged facing each other.

7 is the air outlet. Reference numeral 8 denotes a ventilation fan provided within the ventilation path 9. Reference numeral 14 denotes a reinforcing member for fixing the air outlet 7 of the front cover 1, into which the fulcrum of the rotating shaft 12 is fitted.
15 is a casing that covers the entire back of the air conditioner.
16 is a heat insulating material that insulates the inner surface of the casing 15; 18 is a filter holder that fixes the left and right sides of the pre-filter 4; 19 is a left and right wind direction plate provided at the air outlet 7. 20 is a vertical wind direction plate provided at the air outlet 7. 22 is a dew saucer.

<Effects of the invention> As described above, this invention provides a front door that can be opened and closed extremely smoothly, and eliminates the possibility of the front door hitting obstacles when opening and closing. .
