Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to an air purifier configured to electrically ionize and collect dust contained in intake air.

(Prior Art) Conventionally, in this type of air purifier, an electric ionization device, a filter, and a fan device are arranged inside a main body case having an intake port and an exhaust port to operate them. As a result, the air outside the main body case is sucked through the intake port and passed through the electric ionization device, the filter and the fan device in this order, whereby the dust contained in the intake air is electrically ionized and attached to the filter. There is provided a device in which room air is cleaned by discharging clean air from which dust has been removed from a discharge port.

Thus, in this one, the filter is provided with a charging member on the back side thereof having the same potential as the counter electrode plate of the ionization device, so that the dust in the ionized state can be favorably adsorbed to the filter. There is. This charging member is electrically connected to the counter electrode plate by a lead wire so as to have the same potential as the counter electrode plate.

The main body of the case is composed of a cover for covering the front plate portion mainly of the case from the front in the presence of a space, and the air outside the main body case provided inside the main body of the case is sucked from the intake port and the ventilation port is provided. And a discharge device for electrically ionizing dust contained in the air sucked from the intake port, which is provided in the space, and a counter electrode plate paired with the discharge line. An ionization device, a filter that is provided in the space so as to cover the vent hole, and that adheres dust ionized by the ionization device, and a charging member, the counter electrode plate It is characterized in that the conducting connection between the charging member and these counter electrode plate directly both ends of the conductive member to press and hold the front of the front plate portion of the case main body.

(Operation) According to the above means, since the charging member is directly conductively connected to the counter electrode plate, the two can be electrically connected without the lead wire, which facilitates the wiring process and the number of parts. Can contribute to reduction. The conductive connection is made by pressing and holding both end portions of the charging member against the front surface of the front plate portion mainly composed of the case by the counter electrode plates, so that both end portions of the charging member are securely held by the front plate portion and the counter electrode plate. Therefore, the warp deformation of both ends of the charging member can be prevented, and the conductive connection can be ensured.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

First, in FIG. 2, reference numeral 1 is a main body case, which comprises a case main body 2 and a cover 3. The case main body 2 has a vent hole 7 in its front plate portion 2a, and also has an exhaust port 5 in a predetermined portion, for example, the upper plate portion 2b. The cover 3 is detachably attached to the front plate portion 2a of the case main body 2 by a plurality of engaging claws (not shown), and a space 21 is formed between the cover 3 and the front plate portion 2a. There is. Further, an intake port 4 is formed at a predetermined portion of the cover 3, for example, both side plate portions (only one side plate portion on the right side is shown in FIG. 2).

Next, referring to FIG. 3, reference numeral 6 denotes a fan device provided inside the case main body 2, which is attached to the motor 8 disposed in the central portion of the vent hole 7 of the case main body 2 and the rotary shaft of the motor 8. And a centrifugal blower blade 9 housed inside the case body 2, and the inside of the case body 2 is used as a casing. Reference numeral 10 denotes a filter provided in the space 21, which is mainly composed of, for example, felt or the like, and activated carbon or the like is mixed therein. On the back side of the filter 10, a charging member 11 made of, for example, a wire mesh is used.
The charging member 11 is fixed to a screw seat 2c formed on the front plate portion 2a of the case main body 2 with a screw 11a.
Thus, the vent hole 7 of the case main body 2 is covered from the front by the whole.

On the other hand, 12 is an ionization device provided in the space 21, which forms a pair with the discharge lines 13 respectively arranged on both sides of the front plate 2a of the case main body 2. The counter electrode plate 14 is composed of two long electrode plates 15a and 15b electrically connected at both ends.

Here, as shown in FIG. 1, both ends of the charging member 11 are pressed and held on the front surface of the front plate portion 2a of the case main body 2 by the electrode plates 15a of the counter electrode plates 14, The charging member 11 is connected to the counter electrode plate 14 in a state of being directly electrically connected thereto, and therefore has the same potential (ground level) as the counter electrode plate 14. In this case, the left and right counter electrode plates 14,14
Is electrically connected by this charging member 11. Reference numeral 16 is a pre-filter provided on the case main body 2 located on the side of each of the intake ports 4 from the ionizer 11. The pre-filter 16, the ionizer 12, the filter 10, and the charging member 11 are covered by a cover 3 attached to the case main body 2.

FIG. 4 shows an electrical configuration. In the figure, 17 is a control unit for driving and controlling the motor 8, and 18 is a discharge line 13 of the ionizer.
A high-voltage circuit that applies a high voltage between the counter electrode plate 14 and the counter electrode plate 14.

Now, in the case of the configuration described above, when the operation is started with the cover 3 attached to the case main body 2, the motor 8 of the fan device 6 is energized to rotationally drive the centrifugal blower blades 9 and, at the same time, the ionization device. 12 discharge lines 13 and counter electrode plate
A high voltage is applied between 14 and 14 to discharge. Therefore, based on the rotation of the centrifugal blower blade 9, the air outside the main body case 1 is sucked from the air inlet 4, and the sucked air first passes through the pre-filter 16 to remove coarse dust, and then the ionizer. The minute dust left by passing between the discharge line 13 and the counter electrode plate 14 of 12 is ionized, and the ionized dust is charged by the charging member 11 in an electrically conductive state with the counter electrode plate 14 Adhere exclusively to 10. In this way, the dust that adheres to the filter 10 and the air that has passed through the filter 10 is then discharged from the air outlet 5 to the outside of the main body case 1 through the vent hole 7 and the inside of the case main body 2. Repeat the procedure to purify the air in the room where the air purifier is installed.

According to this embodiment having the above-mentioned configuration, the charging member 11 is directly conductively connected to the counter electrode plate 14, so that the lead wire between the two can be eliminated, and thus the wiring process is extremely easy.
Further, the number of parts can be reduced, and the cost can be reduced as a whole. Furthermore, since the above-mentioned conductive connection is made by pressing and holding both ends of the charging member 11 against the front surface of the front plate portion 2a of the case main body 2 by the counter electrode plate 14, both ends of the charging member 11 of the case main body 2 are connected. The front plate portion 2a and the counter electrode plate 14 can be surely pinched, and thus the warp deformation of both ends of the charging member 11 can be prevented, whereby the filter 10 does not roll up at both ends thereof. In addition, the conductive connection can be ensured.
