Abstract
An air conditioner includes a discharge electrode. The discharge electrode is arranged at a location spaced by a distance between the discharge electrode and a dust collecting electrode or greater. The discharge electrode also is positioned in a main stream of an air flow caused by a cross flow fan. The dust collecting electrode is provided at a location outside the main stream of the air flow and downstream of the discharge electrode relative to a direction of the air flow.
Description
The present invention relates to air conditioner, particularly relate to and a kind ofly can collect the air conditioner that is suspended in airborne fine grained (dust), it is to give these dusts electrically charged by corona discharge, realizes on the collecting electrode thereby utilize electric field force that charged dust granule is collected.
Traditional such air conditioner with on December 10th, 1991 disclosed Japanese Utility Model publication number H3-119443 be that example is disclosed.Described as the disclosure text, a kind of collecting unit of dust of collecting dust in the air with electronic method is arranged between a filter and the heater.This filter is arranged near the suction inlet, and to catch bigger dust, heat exchanger is used for the air by filter is carried out heat exchange.
In the prior art, collecting unit of dust is arranged near the suction inlet (filter), can run into a problem like this, and promptly collecting unit of dust stops flowing with near the air velocity the minimizing collecting unit of dust of air, causes the reduction of dust capacity gauge.In the air conditioner of routine, do not consider the problem that air conditioner hollow air-flow is moving, collecting unit of dust is arranged on the low position of air velocity.For this reason, be difficult to reach the dust collecting effect of expection.And, also having a worry, the dust that had once captured is flowed by air and dispels.
Simultaneously, collecting electrode and not removable ground installed filters require regularly to clean.This has caused a problem that needs time and manpower to reach high-efficiency dust collecting.In addition, must have a constant spacing to place collecting unit of dust between filter and heat exchanger, this causes that again whole air conditioner size becomes big problem.
Therefore, main purpose of the present invention provides an air conditioner, and it is little and can reduce the time and the work of maintenance that it has excellent control of dust ability and size.
Air conditioner of the present invention comprises: have a casing of air suction inlet and floss hole, this floss hole discharging is by the suction inlet inhaled air; A filter that links to each other with suction inlet is used for catching by the contained dust of suction inlet inhaled air; A heat exchanger is used for the air by filter is carried out heat exchange; A cross flow fan that is provided with in casing produces one and flows by the air of heat exchanger to floss hole from suction inlet; An electronic dust-collecting unit is arranged on the back location of heat exchanger in the casing, also comprises a sparking electrode and collecting electrode of space certain distance, and wherein, sparking electrode is arranged on the position of leaving the heat exchanger certain distance.
When the cross flow fan rotation, in casing, be formed into one air-flow by heat exchanger to floss hole from suction inlet.Sparking electrode is arranged on the back location of heat exchanger in the casing and the position of mainstream that flows at air, and collecting electrode is arranged on the outside of main flow and the downstream of the direction sparking electrode that relative air flows.Collecting electrode is preferably on sparking electrode ambient air flow vector and the extension line by the resultant vector of the electric field force between sparking electrode and the collecting electrode (Coulomb force).Because the high electric field that sparking electrode and collecting electrode produce, the dust of positive charge is subjected to the electric field force effect.These particles move and by its seizure to collecting electrode.The dust that is collected on collecting electrode is by the heater heating and the decomposition of electrode interior.Because collecting electrode is arranged on the main flow outside of air stream, needn't worry that the dust of once being caught by collecting electrode is dispelled by air stream.In addition, collecting electrode is suitably cooled off by air stream and prevents that temperature from raising.
In addition, determine that size of gaps between sparking electrode and the heat exchanger is greater than the size of gaps between sparking electrode and the collecting electrode.Like this, dust in air is collected on the collecting electrode exactly and corona discharge between sparking electrode and the hot heater can not take place.
In addition, because collecting electrode is positioned at the position of a preset distance of cross flow fan that forms away from plastic resin, cross flow fan is avoided cause thermal damage by heater to the automatically cleaning of the dust on the collecting electrode.
According to the present invention, sparking electrode is arranged on the position of mainstream of air stream and away from the certain or bigger distance of heat exchanger, collecting electrode is arranged on the downstream position of air stream main flow outside and sparking electrode simultaneously.Therefore, can collect the dust that charges by sparking electrode effectively.
In addition, heater is arranged in the collecting electrode with burning and decomposes dust on the collecting electrode, thereby, needn't maintain and clean collecting electrode.Collecting unit of dust can be arranged on the back of heat exchanger in the casing, thereby reduces the size of air conditioner.In addition, for example around the cross flow fan etc. parts can not be subjected to the influence of heat.
Purpose of the invention described above and specific and superiority detailed description of the present invention in conjunction with the drawings will become more apparent.

An air conditioner 10 shown in Fig. 1 embodiment, comprises one by synthetic resin, the casing 12 that forms of plastic resin for example, this casing 12 has an opening 14a and 14b in its front, opening 14a is as a suction inlet, and opening 14b is positioned at the following as a floss hole of opening 14a.Below opening 14a and 14b are called suction inlet and floss hole.
A filter 16 is contained between suction inlet 14a and the heat exchanger 18 movably.Filter 16 is by filter fiber, and for example glass or glass fibre constitute.Heat exchanger 18 is arranged on the back of filter 16, thereby heat exchanger places the air of introducing casing 12 by suction inlet 14a.Cross flow fan 20 is arranged on the back of heat exchanger 18 and in the deep of floss hole 14b inside.The rotation of cross flow fan 20 produce one at width (direction of rotating shaft 20a) from suction inlet by the air stream of heat exchanger 18 to floss hole.
An electric dust collecting unit 26 is arranged on the back of heat exchanger 18 in the casing 12, and it comprises a sparking electrode 22 and a collecting electrode 24 of each interval certain distance.Sparking electrode 22 is by steel wire, stainless steel wire, and tungsten filaments etc. are made, and extend along the width (direction of rotating shaft 20a) of air conditioner 10.On the other hand, collecting electrode 24 comprises rod heater 28.This heater 28 is contained in the shell 30, and this shell 30 is cylindrical, has by using the ceramic layer of contact medium encapsulation heater 28.Surface at housing 30 (collecting electrode 24) is heated to 200 ℃-350 ℃ by heater 28, thereby makes the dust on surface resolve into water and carbon dioxide by oxidation.The collecting electrode 24 that is Fig. 1 embodiment has self-cleaning function.
As seen from Figure 2, described sparking electrode 22 is positioned at the position of air main flow after the heat exchange, and on the other hand, collecting electrode 24 is positioned at the outer downstream with relative air-flow direction sparking electrode 22 of main flow.That is to say that as shown in Figure 3, collecting electrode 24 is positioned on the extension line of the resultant vector (F) of the Coulomb force (Fq) of generation between sparking electrode 22 ambient air flow vector (Fw) and discharge electroplax 22 and the collecting electrode 24.Therefore, as shown in Figure 4, the charged particle that is produced by sparking electrode is attracted on the collecting electrode 24 in the mode of the arc of imagination.Dust granule is attracted to continuously on the collecting electrode 24 and can not be dispelled by air stream.These particles are decomposed by heater 28.
In addition, sparking electrode 22 and collecting electrode 24 are provided with relation below satisfying like this in the present embodiment, and promptly the size of gaps (De) between sparking electrode 22 and the heat exchanger 18 is greater than the size of gaps (Dc) between sparking electrode 22 and the collecting electrode 24.For this reason, the corona discharge between sparking electrode 22 and the heat exchanger 18 can not appearred in dust in air reliably by collecting electrode 24 collections.In addition, collecting electrode 24 is in the casing 12 that forms away from synthetic resin and the position of cross flow fan 20 certain distances, thereby casing 12 and cross flow fan can not be subjected to overheated influence.
In the air conditioner 10 that so constitutes, if cross flow fan 20 rotates and (for example apply high voltage between sparking electrode 22 and collecting electrode 24,9KV), catch by suction inlet 14a introducing casing 12 and owing to rotating of cross flow fan 20 is filtered device together relative to big dust and air.Air by filter after cooling or heat on by the path of heat exchanger 18.Corona discharge between sparking electrode 22 and the collecting electrode 24 produces cation on sparking electrode 22.These cations move on the collecting electrode 24 along power line.For this reason, dust in air is back owing to the distance between the electrode-electric utmost point is filled with positive electricity by filter 16 and heat exchanger 18.The effect that is subjected to electric field force in the high electric field of charged particle between electrode is moved to collecting electrode 24, thereby is caught by collecting electrode 24.Air by heat exchange and dedusting is discharged into house interior through floss hole 14b.
As mentioned above, the position of sparking electrode 22 and collecting electrode 24 is determined under the situation of Coulomb force between the air stream of having considered casing 12 and sparking electrode 22 and the collecting electrode 24.Therefore, use the power of air stream and the composite force of electric field force (Coulomb force), can make dust charged effectively, thereby catch charged particle effectively by collecting electrode 24.In addition, because collecting electrode 24 places the outside of the main flow of air stream, thereby in a single day dust is captured and will can not be dispelled by air stream.And, around collecting electrode 24, there is a suitable air stream, collecting electrode 24 avoids being subjected to the heat affecting of crossing of heater 28.
In addition, because sparking electrode 22 is positioned at and leaves heat exchanger 18 certain distances, between sparking electrode and collecting electrode 24, can produce corona discharge effectively, thereby collecting electrode 24 can be caught dust.Must worry that hardly by synthetic resin, for example parts can not cause thermal deformation by heater 28 around cross flow fan 20 grades of plastic resin formation.
In addition, in the above-described embodiments, casing 12, the shape and the installation site of filter 16 and heat exchanger 18 are unrestricted.Say nothing of they are applied in the air conditioner of the heat exchanger that adopts curved shape as shown in Figure 6 and Figure 7.
Although the present invention at length is described, should be clear and definite be to describe and example only is in order to illustrate rather than in order to limit, the spirit and scope of the present invention are only limited by appended claim.
