Description

Technical Field

[0001] The present invention relates to a dust collection unit and an electric dust collection device including the dust collection unit, and more particularly, to such a dust collection unit and an electric dust collection device including the dust collection unit, wherein a membrane is inserted into an insertion groove formed in a housing, and conductive terminals are inserted to simultaneously electrically connect multiple membranes, thereby easily and conveniently electrically connecting the membranes and stably maintaining the electrical connection. Background Technology

[0002] Examples of air conditioners include coolers or heaters configured to control the temperature of air, air purifiers configured to maintain cleanliness by removing foreign matter from the air, humidifiers configured to supply moisture to the air, and dehumidifiers configured to remove moisture from the air.

[0003] Electric dust collection equipment refers to equipment that is independently installed or set up in an air conditioner and collects dust particles contained in the air by charging the dust particles.

[0004] Electric dust collection equipment broadly comprises charged units configured to create an electric field and dust collection units configured to collect dust particles charged by the charged units. As air passes through the charged units and then through the dust collection units, the dust contained in the air is collected by the dust collection units.

[0005] The charging unit charges the dust particles by means of corona discharge between the discharge electrodes and the counter electrodes facing each other. The dust collection unit collects the dust particles that have passed through the charging unit and have a specific charge by means of electro-attraction using the property of opposite charges.

[0006] In this regard, Korean Patent No. 1942525 discloses an electric dust collection device, in which dust collection unit membranes with different high voltages are arranged at equal intervals inside the dust collection unit housing, conductive paste is applied and cured to electrically connect the membranes to the power source, and electrical insulation is ensured by applying insulating material.

[0007] However, in related technologies, the cured conductive paste comes into contact with the membrane electrode portion. The problem with this is that the conductive paste and the electrode portion may separate due to external stress, etc., and because the conductive paste needs to be applied and cured, there are disadvantages in terms of working time and unit price.

[0014] The conductive terminal may include: an elongated body; and a plurality of contact protrusions protruding from the body in one direction.

[0015] Each membrane may have an electrode layer inserted between a first insulating membrane and a second insulating membrane, and each membrane may have an electrode exposed portion formed at one or at least one of two opposite ends in the length direction, through which a portion of the electrode layer may be exposed to the outside.

[0016] A connection structure may be provided on at least one side of the housing, wherein the conductive terminal and each membrane of the membrane are provided at one end or the other end based on the length direction, and the conductive terminal and each membrane of the membrane are electrically connected. The connection structure may be formed with a plurality of insertion grooves and a plurality of protrusions alternately formed along one or the other side of the housing. When the end of each membrane of the membrane with the electrode exposed portion is referred to as the exposed end, the exposed end of the membrane can be inserted into the insertion groove of the connection structure, and the contact protrusion of the conductive terminal can be inserted into the insertion groove of the connection structure, so that the electrode exposed portion of the membrane and the contact protrusion can contact each other.

[0017] The contact protrusions of the conductive terminals can be physically inserted into and assembled into the insertion grooves of the connection structure.

[0018] The electrode exposure portion may be formed on the front surface of the exposed end of each membrane in the membrane, and the rear surface of the exposed end is configured to be in close contact with the protrusion.

[0019] The area of ​​the exposed portion of the electrode can be larger than the contact area of ​​the contact protrusion that contacts the exposed portion of the electrode.

[0020] Insulating material can be inserted into the insertion groove of the connection structure, so that the exposed portion of the electrode of the membrane is insulated and sealed.

[0021] The guide groove can be recessed inward in the protruding portion of the connection structure, while the guide groove spans the upper surface of the protruding portion, and at least a portion of the body of the conductive terminal can be inserted into the guide groove, thereby fixing the position of the body.

[0028] Beneficial effects

[0029] According to the dust collection unit of the present invention, a membrane can be inserted into an insertion groove formed in the housing, and a conductive terminal can be inserted into the insertion groove, so that multiple membranes can be electrically connected to each other at the same time, thereby making it easy and convenient to electrically connect the membranes.

[0030] In addition, since the corresponding components are physically fastened, the electrical connection can be stably maintained even if the entire dust collection unit is deformed due to external stress or other factors.

[0049] The present invention will now be described with reference to the accompanying drawings.

[0050] Figure 1 This is a perspective view of an electric dust collection device according to an example of the present invention. Figure 2 It is shown schematically. Figure 1 The figure shows that the electric dust collection device 1 broadly includes a charged unit 10 configured to form an electric field and a dust collection unit 20 configured to collect dust particles charged by the charged unit.

[0051] The charged unit 10 may include: a frame-shaped housing 11 having a central portion formed therethrough in the direction A of dust introduction; charged plates 12 having charged electrodes arranged parallel to the direction of dust introduction; and discharge lines 13 having discharge electrodes disposed between the charged plates 12.

[0052] The dust collection unit 20 is used to collect charged dust particles. This invention relates to the dust collection unit 20 of an electric dust collection device 1, and the dust collection unit 20 is described in detail below.

[0053] Figure 3 This is a perspective view of a dust collection unit according to an example of the present invention. Figure 4 yes Figure 3 Enlarged view of part A in the middle. Figure 5 This shows the view when viewed from another direction. Figure 4 The figure shows that the dust collection unit 20 of the present invention can broadly include a housing 100, a membrane 200, and conductive terminals 300.

[0054] The outer shell 100 can be constructed in the form of a frame. Figure 6This is a perspective view of an example housing according to the invention. The housing 100 may be formed with a border shape having a central portion through which it is formed, allowing dust particles to pass through the central portion, and allowing air to be introduced into and pass through the central portion. As shown, the housing 100 may be formed generally in a quadrilateral shape. Alternatively, the housing 100 may be formed in a circular or polygonal shape.

[0055] Membrane 200 is used to collect charged dust particles. For example... Figure 3 As shown, multiple membranes 200 can be arranged in parallel and spaced apart from each other at a predetermined interval in the alignment direction D1, and the multiple membranes 200 can be housed in the housing 100. One end of the membrane 200 based on the length direction D2 can be fixed to one side of the housing 100, and the other end of the membrane 200 based on the length direction D2 can be fixed to the other side of the housing 100.

[0056] Membrane 200 will be described in detail. Figure 7 This is a front view of an example membrane according to the invention, as viewed from the front side. Figure 8 This is shown when viewed from the top side. Figure 7 The diagram shows a top view of part B. The membrane 200 may have a structure in which the electrode layer 230 is inserted between the first insulating membrane 210 and the second insulating membrane 220, and the edges of the electrode layer 230 are sealed. An electrode exposure portion 230A may be formed along the length direction at at least one of the two opposite ends of the membrane 200, through which a portion of the electrode layer 230 is exposed to the outside.

[0057] As shown in the figure, the membrane 200 can extend in the length direction D2. A predetermined protruding blade portion 200A can be provided at one end of the membrane 200 in the length direction and at the other end of the membrane 200 in the length direction. The blade portion 200A can be fixedly inserted into the insertion groove 111 formed in the housing 100. Details will be described below.

[0058] In this configuration, the electrode exposed portion 230A can be formed on at least one of the blade portions 200A disposed on two opposite sides of the membrane 200. When at least one of the first insulating film 210 and the second insulating film 220 disposed on two opposite surfaces of the electrode layer 230 is not formed at a specific location, the electrode exposed portion 230A can be formed such that the electrode layer 230 is exposed to the outside at that specific location. Alternatively, as shown, the blade portion 200A on which the electrode exposed portion 230A is not formed can be formed solely of the first insulating film 210 and the second insulating film 220, which are sealed to each other.

[0059] Conductive terminals 300 may be disposed on at least one side of the housing 100, and electrically connected to a plurality of membranes 200. That is, the conductive terminals 300 are a busbar configured as rod-shaped conductors. The conductive terminals 300 may be disposed along an alignment direction D1 on one or the other side of the housing 100, electrically connected to the membranes 200, and configured to transmit voltage to the membranes 200. More specifically, Figure 9 This is a diagram illustrating an example of a conductive terminal according to the invention. The conductive terminal 300 may include an elongated body 310 and a plurality of contact protrusions 320 projecting from the body 310 in one direction. The body 310 may be provided in the form of a long rod and extend to a length corresponding to one side or the other side of the housing 100. The contact protrusions 320 have the same size and shape and are spaced apart from each other at equal intervals. The end portions 320B of the contact protrusions 320 may have curved edges, which facilitates insertion of the contact protrusions 320 into insertion recesses 111 formed in the housing 100.

[0060] The housing 100 of the present invention will be described in more detail. Figure 10 yes Figure 6 An enlarged view of part A in the image, and Figure 11 This is shown when viewed from the top side. Figure 10 The figure shows a top plan view. As shown, a predetermined connecting structure 110 can be disposed on one side of the housing 100, and the connecting structure 110 can have a structure in which a plurality of insertion grooves 111 and a plurality of protrusions 112 are alternately formed along one side of the housing 100. The connecting structure 110 can be disposed not only on one side of the housing 100, but also on at least one side of the housing 100 and the other side. In the following description, for ease of description, as in the example shown, the description will focus on the construction of the connecting structure 110 formed on one side of the housing 100.

[0061] Furthermore, in this respect, as described above, the electrode exposed portion 230A can be formed on at least one of the blade portions 200A disposed at one end and the other end (i.e., two opposite sides of the membrane 200 based on the length direction). In the following description, for ease of description, as in the example shown, the description will focus on the configuration where the electrode exposed portion 230A is formed on one side of the membrane 200 based on the length direction. In this case, the end of the membrane 200 on which the electrode exposed portion 230A is formed will be referred to as the exposed end.

[0062] The connecting structure 110, in which the insertion groove 111 and the protrusion 112 are alternately arranged along one side of the housing 100, can be provided on one side of the housing 100 of the dust collection unit 20 of the present invention. In this case, the exposed end of the membrane 200 is inserted into the insertion groove 111 of the connecting structure 110, and the contact protrusion 320 of the conductive terminal 300 is inserted into the insertion groove 111, so that the electrode exposed portion 230A of the membrane 200 can contact the contact protrusion 320.

[0063] Figure 12 It is a diagram showing the state of the membrane being inserted into the insertion groove, and Figure 13 This is shown when viewed from the top side. Figure 12 The figure shows that the exposed end of the membrane 200 (i.e., the end of the membrane 200 where the electrode exposed portion 230A is formed) can be identical in the insertion groove 111. Furthermore, Figure 14 This diagram shows the state in which a conductive terminal is inserted into an insertion groove into which a membrane is inserted, and Figure 15 This is shown when viewed from the top side. Figure 14 As shown in the figure, the conductive terminal 300 can be disposed and placed on one side of the housing 100, and the contact protrusion 320 of the conductive terminal 300 is inserted into the insertion groove 111 into which the exposed end of the membrane 200 is inserted, so that the electrode exposed portion 230A of the membrane 200 can contact the contact protrusion 320 respectively.

[0064] In this case, the width of the contact protrusion 320 can be substantially equal to the width of the insertion groove 111, so that the contact protrusion 320 can be physically inserted into and fitted into the insertion groove 111.

[0065] Furthermore, referring to the membrane 200 inserted into the insertion groove 111, the electrode exposed portion 230A can be formed on the front surface of the exposed end of the membrane 200, and the rear surface of the exposed end of the membrane 200 can be configured to be in close contact with the protrusion 112. That is, the membrane 200 can be inserted into the insertion groove 111 such that the membrane 200 is in close contact with the wall surface of the protrusion 112 provided on one side of the insertion groove 111. Therefore, the contact protrusion 320 of the conductive terminal 300 can be easily inserted into the insertion groove 111 in which the membrane 200 is inserted.

[0066] Figure 16 This is a diagram showing the structure in which the membrane and conductive terminals are inserted into the insertion groove and connected to each other. Figure 16 (A) shows the membrane being inserted into the insertion groove, and Figure 16 (B) shows the insertion of a conductive terminal into an insertion groove into which a membrane is inserted. Figure 17 This shows the view from the lateral side. Figure 16 The image. Figure 17(A) shows the membrane being inserted into the insertion groove, and Figure 17 (B) shows the insertion of a conductive terminal into an insertion groove into which a membrane is inserted.

[0067] In other words, in the dust collection unit 20 of the present invention, a plurality of insertion grooves 111 are formed on one side of the housing 100. The end of the membrane 200 with the electrode exposed portion 230A is inserted and placed in the insertion groove 111, and the contact protrusion 320 of the conductive terminal 300 is inserted and fitted into the insertion groove 111 in which the membrane 200 is inserted, so that the electrode exposed portion 230A of the membrane 200 contacts the contact protrusion 320. Therefore, a plurality of membranes 200 can be electrically connected simultaneously.

[0068] As described above, according to the present invention, conductive terminals are inserted and physically secured between the housing and the exposed electrodes of the membrane, allowing multiple membranes to be electrically connected to each other simultaneously by means of a single process of securing the conductive terminals. Therefore, the membranes can be easily and conveniently electrically connected to each other within the dust collection unit.

[0069] Furthermore, since the corresponding components are physically fastened, the electrical connection can be stably maintained even if the entire dust collection unit deforms due to external stress. More specifically, in the aforementioned related technologies, when the dust collection unit deforms due to external stress, the cured conductive paste can separate from the film, which may lead to electrical disconnection. In contrast, according to the present invention, even if the dust collection unit deforms, the electrical connection can be properly maintained without the aforementioned problems.

[0070] Furthermore, since electrical connections are accomplished simply by placing a membrane within the housing and inserting conductive terminals, there are advantages in terms of processability and unit price.

[0071] Return to reference Figure 16 As shown in the figure, the area of ​​the electrode exposed portion 230A can be larger than the contact area of ​​each of the contact protrusions 320 that contacts the electrode exposed portion 230A. That is, the exposed area of ​​the electrode layer 230 corresponding to the electrode exposed portion 230A can be larger than the thickness of the conductive terminal 300. Therefore, the two components can contact each other over a larger range, making electrical connection easy to achieve and advantageously maintaining the electrical connection.

[0072] In this configuration, although not shown, an insulating material (silicone, rubber, etc.) can be inserted into the insertion groove 111, so that the remaining portion of the exposed electrode portion 230A, excluding the contact surface that contacts the contact protrusion 320, can be insulated and sealed by the insulating material. Furthermore, although not shown, an insulating cap can be simultaneously or selectively positioned above the conductive terminal 300 and close the conductive terminal 300. The insulating material or insulating cap can improve insulation from the outside, which can improve mechanical stability.

[0073] Return to reference Figure 10 and Figure 11 A guide groove 112A can be formed in the upper surface of each of the protrusions 112 in the connecting structure 110. The guide groove 112A can be configured as a recess that extends inward across the upper surface of the protrusion 112, and at least a portion of the body 310 of the conductive terminal 300 is inserted into the guide groove 112A, thereby fixing its position. Because the guide groove is formed in the protrusion as described above, the position of the conductive terminal can be easily and accurately fixed in the housing, and the conductive terminal can be securely fixed even without additional components. Furthermore, as... Figure 9 As shown, the downwardly protruding predetermined protrusion, the guide protrusion 330, can also be formed between the contact protrusions 320 of the conductive terminal 300 and correspond to the guide groove 112A. The end of the guide protrusion 330 may have a curved edge, so that the guide protrusion 330 can be easily inserted into the guide groove 112A.

[0074] In addition, return to reference Figure 10 and Figure 11 An inclined guide surface 112B may be formed on the upper part of each protrusion 112 in the connecting structure 110 and inclined toward the insertion groove 111. That is, the inclined guide surface 112B may be formed on the upper part of the protrusion 112 and inclined downward from top to bottom for a predetermined length toward the insertion groove 111 on the side corresponding to the upper part of the protrusion 112. Therefore, the entrance of the insertion groove 111 may be wider than the internal space of the insertion groove 111. This allows the membrane to be easily inserted into the insertion groove by being guided along the inclined surface when the membrane is inserted into the insertion groove.

[0075] Meanwhile, as described above, the plurality of membranes 200 are arranged to be spaced apart from each other at a predetermined interval in the alignment direction D1. In this case, it is necessary to maintain the interval appropriately so that the membranes 200 do not contact each other. For this purpose, the interval maintaining portion 120 can be provided on one side and the other side of the housing 100 of the present invention, and maintain the interval between the membranes 200. Return to reference Figure 10 and Figure 11 The spacing maintaining portion 120 may be disposed on one side of the housing 100, that is, disposed inside the connecting structure 110. The spacing maintaining portion 120 may include a first fixing portion 121 and a second fixing portion 122. The first fixing portion 121 is configured to be one surface of each of the supporting films 200, and the second fixing portion 122 is configured to be the other surface of each of the supporting films 200.

[0076] In this case, as shown in the figure, the first fixing portion 121 and the second fixing portion 122 can be arranged obliquely relative to each other. That is, the membrane 200 can be inserted between the first fixing portion 121 and the second fixing portion 122 without the surfaces of the supporting membrane 200 overlapping each other. Because the membrane is very thin, it is difficult to form a thin groove in the housing such that the thin groove corresponds to the membrane, and it is difficult to insert the membrane into the thin groove. Instead, according to the present invention, as described above, the first fixing portion and the second fixing portion are installed diagonally, and the membrane is inserted between the first fixing portion and the second fixing portion, which solves the above-mentioned problem. Figure 10 and Figure 11 Only the spacer maintenance portion 120 provided on one side of the housing 100 is shown. However, the spacer maintenance portion 120 with the same structure may also be provided on the other side of the housing 100.

[0077] Furthermore, the spacing maintaining portion 120 may also include a central portion 123 disposed between the first fixing portion 121 and the second fixing portion 122. The spacing maintaining portion 120 may have a structure in which the first fixing portion 121 protrudes from the central portion toward one side and the second fixing portion 122 protrudes from the central portion 123 toward the other side. This is a specific embodiment that allows for easy installation of the first and second fixing portions in an inclined direction, and this structure also ensures the mechanical durability of the spacing maintaining portion. In this case, of course, the first fixing portion may support one surface of the first membrane, and the second fixing portion may support another surface of the second membrane adjacent to the first membrane.

[0078] In addition, such as Figure 10 and Figure 11 As shown, predetermined inclined guide surfaces 121B and 122B can be formed on the upper parts of the first fixing portion 121 and the second fixing portion 122, and are inclined toward the gap between the first fixing portion 121 and the second fixing portion 122 where the membrane 200 is to be inserted. The inclined guide surfaces 121B and 122B perform the same function as the inclined guide surface 112B of the protrusion 112. Because inclined surfaces are formed on the upper parts of the first and second fixing portions as described above, the membrane can be easily inserted by being guided between the first and second fixing portions.

[0079] Meanwhile, the dust collection unit 20 of the present invention can be configured as a single-layer or multi-layer structure. When the dust collection unit 20 is configured as a single-layer or multi-layer structure, the dust collection unit 20 corresponding to that layer can be configured such that the connecting structure 110 can be formed only on one side of the housing 100, or the connecting structure 110 can be formed on both opposite sides.

[0080] In other words, to enable the dust collection unit to collect charged dust particles, different voltages need to be applied to collect different amounts of charged dust particles. This can be achieved by using a single-layer structure of a single dust collection unit group or by using a multi-layer structure of multiple dust collection unit groups stacked along the upward / downward direction D3. In this case, the dust collection unit group may include a housing 100, multiple membranes 200, conductive terminals 300, and other structures such as a connection structure 110, a spacing maintenance part 120, etc.

[0081] For example, in the case where the dust collection unit group constitutes a multi-layer structure, the structure of any one layer of the dust collection unit group can be configured such that the electrode exposed portions of the multiple membranes are formed at one end of each membrane along the length direction, and conductive terminals can be disposed at one end of each membrane. Conversely, the structure of another layer of the dust collection unit group can be configured such that the electrode exposed portions and conductive terminals are disposed on the opposite side of each membrane. Furthermore, different voltages, such as high potential voltage and low potential voltage, can be applied to the membranes of any one layer of the dust collection unit group and the membranes of another layer of the dust collection unit group.

[0082] Furthermore, when the dust collection unit group constitutes a single-layer structure, the multiple membranes may include a first membrane and a second membrane having electrode exposed portions formed opposite to each other. Conductive terminals may be respectively provided on one side and the other side of the housing; the conductive terminal provided on one side of the housing can be electrically connected to the first membrane, and the conductive terminal provided on the other side of the housing can be electrically connected to the second membrane. In this case, the first membrane and the second membrane can be arranged alternately, and the voltage applied to the first membrane and the voltage applied to the second membrane can be different from each other. Furthermore, the dust collection unit can ultimately be constructed by stacking multiple dust collection unit groups, each constituting a single-layer structure including the first membrane and the second membrane.

[0083] Although embodiments of the invention have been described with reference to the accompanying drawings, those skilled in the art will understand that the invention can be practiced in any other specific form without altering its technical spirit or essential characteristics. Therefore, it should be understood that the above embodiments are illustrative in all respects and do not limit the invention.
