Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an air conditioner, and particularly to an air conditioner incorporating an electrostatic precipitator.

(Prior Art) Conventionally, an air conditioner incorporating this type of electrostatic precipitator has a dust collector formed in a thin shape as shown in Fig. 5 in order to reduce the overall thickness of the air conditioner. Device 1 has been proposed.

That is, in this dust collector 1, a pre-filter 3 is attached to the front of a thin rectangular frame 2, an ionization wire 4 which is a charging part is provided at an intermediate position, and a dust collecting plate 5 which is a dust collecting part is attached to the rear surface. It is formed by This pre-filter 3 removes coarse kiln dust from the air, and the ionization line is connected to a high positive voltage (for example, 3.6
KV) is applied to cause corona discharge and give a positive charge to the ultra-fine dust that has passed through the pre-filter 3, and the dust collection plate 5 is charged with a negative potential to collect the ultra-fine dust that has a positive charge. It works by electrostatically attracting dust and removing it.

Further, in order to clean the prefilter 3 and the dust collecting plate 5 to prevent clogging, this type of dust collector 1 must be installed so that it can be freely moved into and out of the air conditioning unit.

For this reason, conventionally, as shown in FIG. 6, the front panel 7 of the air conditioner case 6 was formed so that it could be opened and closed via a hinge 8 as shown by the arrow a in the figure. Filter 9 and storage guide 1 attached to
The dust collector 1 was formed so that it could be freely inserted and pulled out between the two.

(Problems to be Solved by the Invention) However, forming the front panel 7 as shown in FIG. It was not possible to fully formulate the idea.

Further, the ionization wire 4 and the dust collection plate 5 of the dust collector 1 are energized by pressing them onto a contact piece 11 provided at the bottom of the storage guide 10 to charge them with a positive potential and a negative potential. Therefore, when opening/closing the front panel 7 or when the heat exchanger 1
The connection with the contact piece 11 is often incomplete due to rotational vibration of the blower fan 13 provided at the back of the contact piece 2, and there are also disadvantages such as a poor dust collection effect.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a front panel that is pivoted at one end and opens and closes the front of the air conditioner main body, and a Equipped with an electric precipitator for air conditioners installed between the front panel and the heat exchanger of the air conditioner,
The electrostatic precipitator for an air conditioner is configured to be detachably attached to the front surface of the heat exchanger using a member that can be attached to and detached from the constituent members of the heat exchanger.

(Function) According to the above configuration, since the electrostatic precipitator can be directly and detachably attached to the front of the heat exchanger of the air conditioner using the mounting members, the conventional storage guide can be attached to the front panel of the air conditioner. It is not necessary to provide

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, a rectangular frame 2 of a dust collector 1 is used as shown in FIG.
The members 14 are fixed to the upper and lower sides of both sides with screws 15, respectively. For this attachment, a notch 17 is formed at the tip of the member 14 to be elastically pressed into engagement with the refrigerant pipe 16 of the heat exchanger 12. In addition, as shown in FIG. 4, the dust collecting plate 5 is attached to the heat exchanger 1
A metal leaf spring type grounding member 18 electrically connected to 2.
is installed. This grounding member 18 may be fixed in advance to the heat exchanger 12 as shown in FIG.

Next, in the air conditioner shown in FIG. 3 to explain the operation of this embodiment, the front panel 7 is opened by pulling it toward you centering on the hinge 8, and then the heat exchanger fixed in the air conditioner case 6 is opened. The dust collector 1 is moved closer to the heat exchanger 12 as shown by the arrow C in FIG. The notch 17 is pushed in elastically to engage the refrigerant pipe 16 (FIG. 2.3), and then the front panel 7 is closed. As a result, the dust collector 1 is fixed to the heat exchanger via the mounting member 14, and the ground member 18 is pressed by the fins 19 of the heat exchanger 12, so that the dust collector 1 and the dust collector plate 5 exchange heat. Since the dust collecting plate 5 and the heat exchanger 12 are electrically connected to each other, electric charges will not be accumulated between the dust collecting plate 5 and the heat exchanger 12.

Thereby, even if the heat exchanger 12 is touched when the electrostatic precipitator 1 is removed after operation of the electrostatic precipitator 1, an electric shock will not occur.

Furthermore, when the electrostatic precipitator 1 is installed, the member 14 ensures that the positional relationship with the heat exchanger 12 is normal, that is, a certain distance is maintained, and the electrical connection is stable without short circuits. It turns out.

Furthermore, if the member 14 is made of an elastic material (for example, polypropylene), the dust collector 1 can be repeatedly attached and detached.

In addition, the mounting member 14 is not limited to the one in the above embodiment.
Other components of the heat exchanger 12, such as end plates of the heat exchanger 14, may be engaged or disengaged, or other known coupling devices may be used.

Further, the connection between the electric precipitator 1 and the power supply section is made by a connector (socket), and as shown in Fig. 2, the power supply section 2
The connector 22 of the lead wire 21 from 0 is connected to the ionization wire 4 of the electrostatic precipitator 1, simplifying the electrical connection when attaching and detaching the electrostatic precipitator 1, thereby improving service and maintainability. .

Then, the electrostatic precipitator 1 is removed by following the above-mentioned installation procedure in reverse.

〔Effect of the invention〕

As described above, according to the air conditioner with an electrostatic precipitator of the present invention, the front panel is pivotally connected at one end and can be opened and closed, and the attachment provided on the electrostatic precipitator is a member that connects the electrostatic precipitator. Since it is configured so that it can be detachably attached directly to the front of the heat exchanger of an air conditioner, there is no need to provide a conventional storage guide on the front panel of the air conditioner, and the air conditioner can be made thinner. .

Furthermore, by attaching the electrostatic precipitator to the front surface of the fixed heat exchanger, the structure is simple, and it can be easily attached and detached by simply opening and closing the front panel, and costs can be reduced.
