Description

Technical Field

[0001] This invention relates to air conditioners, and more specifically, to an air conditioner installed in an indoor space. Background Technology

[0002] An air conditioner is a device that regulates the temperature of an indoor space by expelling air that has undergone heat exchange into the room.

[0003] Air conditioners can be installed in indoor spaces to supply heat to the space by exchanging heat with air flowing in from outside or air circulating within the space. Air conditioners installed in indoor spaces can be mounted on the floor, walls, or ceiling.

[0004] The size of an air conditioner can vary depending on the size of the indoor space. Furthermore, when the size of the air conditioner changes, the sizes of its intake and exhaust ports can also be altered.

[0005] Air conditioners can be equipped with filters to remove foreign objects from the intake air. Pre-filters or electrostatic precipitators can be installed at the air conditioner's intake.

[0006] In the case of electrostatic precipitators, which are manufactured from multiple structures, there is a problem that additional manufacturing processes are required when the size changes. This can lead to increased costs associated with the manufacturing process.

[0007] Korean Patent Publication No. KR 10-2020-0111571 discloses an electrostatic precipitator filter for installation in a wall-mounted air conditioner. However, since the disclosed electrostatic precipitator filter is a standardized and fixed-size filter, it is difficult to use when the size of the suction inlet changes. Summary of the Invention

[0008] The problem to be solved by the present invention is to provide an air conditioner including an electrostatic precipitator whose size can be adjusted according to the size of the inlet.

[0009] Another objective of this invention is to provide an air conditioner in which the electrostatic precipitator filter or the filter handle can be structurally joined or separated through a simple structure.

[0010] Another objective of this invention is to provide an air conditioner that makes an electrical connection when installing an electrostatic precipitator or filter handle.

[0011] Another objective of the present invention is to provide an air conditioner capable of preventing safety accidents that occur when the electrostatic precipitator is removed from its casing.

[0012] The subject matter of this invention is not limited to the subject matter mentioned above, and other subject matters not mentioned can be clearly understood by those skilled in the art from the following description.

[0013] To achieve the above-mentioned objectives, an air conditioner according to an embodiment of the present invention includes: a housing having an intake port formed on one side and an exhaust port formed on the other side; a fan disposed inside the housing to create airflow from the intake port to the exhaust port; and an electrostatic precipitator disposed inside the housing to remove foreign matter from the air flowing into the intake port, thereby filtering the air flowing into the intake port. The electrostatic precipitator includes: at least one electrostatic filter, including a first sidewall and a second sidewall disposed in the opposite direction to the first sidewall; a first filter handle attached to the first sidewall; and a second filter handle attached to the second sidewall, thereby allowing one or more electrostatic filters to be disposed between the first filter handle and the second filter handle.

[0014] The first sidewall is provided with a first connecting protrusion protruding outward and a first connecting groove recessed inward, and the second sidewall is formed with a second connecting protrusion protruding outward and a second connecting groove recessed inward, thereby allowing a plurality of electrostatic precipitators to be connected to each other.

[0015] The first connecting protrusion and the first connecting groove are spaced apart from each other on the first sidewall in the front-back direction, and the second connecting protrusion and the second connecting groove are spaced apart from each other on the second sidewall in the front-back direction, thereby allowing a plurality of electrostatic precipitators to be connected together.

[0016] The first and second connecting protrusions are arranged in opposite directions in the front-to-back direction, thereby allowing a plurality of electrostatic precipitators to be combined with each other.

[0017] The first sidewall has a structure corresponding to the second sidewall, the first connecting protrusion has a structure corresponding to the second connecting groove, and the first connecting groove has a structure corresponding to the second connecting protrusion, thereby allowing a plurality of electrostatic precipitators to be coupled together.

[0018] The first filter handle is provided with a first corresponding protrusion and a first corresponding groove. The first corresponding protrusion protrudes from a first corresponding wall opposite to the first sidewall to be inserted into the first connecting groove. The first corresponding groove is recessed into the inside of the first filter handle to allow the first connecting protrusion to be inserted, thereby allowing a plurality of electrostatic precipitators to be connected to each other.

[0019] The electrostatic precipitator includes a button for securing the electrostatic precipitator, the first filter handle, or the second filter handle. The button includes: a first button protrusion protruding upward from the upper surface of the electrostatic precipitator; a restoration plate restoring the position of the first button protrusion; and a second button protrusion configured to protrude from the first or second button protrusion and move together with the first button protrusion, thereby enabling the interconnected electrostatic precipitators to engage and disengage.

[0020] A first fixing groove corresponding to the second button protrusion can be formed on one side of the first mating groove, and a second fixing groove corresponding to the first button protrusion can be formed on one side of the second mating groove.

[0021] The first fixing groove and the second fixing groove are respectively formed in a direction inclined to the direction in which the first connecting groove or the second connecting groove extends, thereby making it easy to connect the electrostatic precipitators.

[0022] The electrostatic precipitator filter includes: a housing forming the exterior and forming an opening for airflow; a plurality of first electrostatic precipitators disposed inside the housing, spaced apart from each other, and subjected to a high voltage; a plurality of second electrostatic precipitators disposed inside the housing and between the plurality of first electrostatic precipitators, and subjected to a low voltage relative to the voltage applied to the plurality of first electrostatic precipitators; a first contact bracket configured to contact the plurality of first electrostatic precipitators respectively; and a second contact bracket configured to contact the plurality of second electrostatic precipitators respectively, the ends of each of the first and second contact brackets protruding outward from the housing, thereby enabling electrical connection when the electrostatic precipitator filter is connected to a filter handle or another electrostatic precipitator filter.

[0023] The first contact bracket and the second contact bracket may each include: a contact body configured to contact a plurality of the first electrostatic precipitators or a plurality of the second electrostatic precipitators; a first contact end exposed to one side of the housing and disposed on one side of the first coupling protrusion or the second coupling protrusion; and a second contact end exposed to the other side of the housing and disposed on one side of the first coupling groove or the second coupling groove.

[0024] The length by which the first contact end protrudes outward from the housing is different from the length by which the second contact end protrudes outward from the housing. Therefore, the first contact end and the second contact end do not hinder the connection between the electrostatic precipitator and the filter handle or another electrostatic precipitator.

[0025] The first contact end is configured to protrude more than the sidewall forming the first or second bonding protrusion, and the second contact end is configured not to protrude more than the sidewall forming the first or second bonding groove, thereby allowing the first and second contact ends to connect when the electrostatic precipitators are coupled together.

[0026] The first filter handle and the second filter handle each include: an inner cover forming a corresponding wall opposite to the electrostatic precipitator; an outer cover disposed on one side of the inner cover, including a side wall disposed in the opposite direction to the corresponding wall and mounted to the outer side wall of the housing; a first connector configured to protrude from the corresponding wall of the inner cover; and a second connector spaced apart from the first connector and configured to protrude from the corresponding wall of the inner cover. When the first filter handle or the second filter handle is connected to the electrostatic precipitator, the first connector and the second connector respectively contact the first contact end and the second contact end of the first contact bracket and the second contact bracket, thereby allowing the first filter handle and the second filter handle to be slidably coupled to the electrostatic precipitator.

[0027] The corresponding walls of the first filter handle and the second filter handle may be provided with corresponding grooves and corresponding protrusions. The corresponding grooves are for the insertion of the first engaging protrusion formed on the first side wall or the second engaging protrusion formed on the second side wall. The corresponding protrusions are inserted into the first engaging groove formed on the first side wall or the second engaging groove formed on the second side wall.

[0028] The corresponding protrusion and the corresponding groove disposed on the first filter handle may be disposed in the opposite direction to the corresponding protrusion and the corresponding groove disposed on the second filter handle.

[0029] The outer sidewalls of the first filter handle and the second filter handle may be provided with protruding fixing protrusions to fix the first filter handle and the second filter handle to the housing respectively.

[0030] The first connector is configured to protrude from the wall surface forming the corresponding protrusion, and the second connector is configured not to protrude from the wall surface forming the corresponding groove, so that the filter handle and the electrostatic precipitator can be electrically connected when slidably engaged between them.

[0031] The first connector includes: a first connecting plate configured to protrude from the inner cover to contact the first contact support of the electrostatic precipitator; and a first exposed plate configured in a first connector hole formed in the outer cover. The second connector includes: a second connecting plate contacting the second contact support of the electrostatic precipitator; and a second exposed plate configured in a second connector hole formed in the outer cover. The first connecting plate is configured to protrude beyond the wall forming the corresponding protrusion, and the second connecting plate is configured not to protrude beyond the wall forming the corresponding groove, thereby ensuring that the connector does not obstruct the connection between the filter handle and the electrostatic precipitator.

[0032] The first connector includes a first contact plate extending from the first exposed plate toward the direction in which the second connector is disposed, and the second connector includes a second contact plate extending from the second exposed plate toward the direction in which the first connector is disposed. The first filter handle and the second filter handle each include a switch disposed between the first connector and the second connector to short-circuit or de-short-circuit the first contact plate and the second contact plate with each other, thereby allowing the first connector and the second connector to be short-circuited when the electrostatic precipitator is separated from the housing.

[0033] Specific details of other embodiments are included in the detailed description and accompanying drawings.

[0034] The air conditioner according to the present invention has one or more of the effects described below.

[0035] First, because the electrostatic precipitator filters configured between the two filter handles have corresponding structures, they have the advantage of being able to adjust the size of the electrostatic precipitator to correspond to the size of the air conditioner.

[0036] Secondly, since the electrostatic precipitator and the filter handle have a structure that slides together and a corresponding structure, they also have the advantage of being easy to assemble and manufacture.

[0037] Third, in the structure that is joined by sliding means, the contact end of the joint is provided with an electrical contact end, which also has the advantage of being able to be electrically connected to each other when connecting multiple electrostatic precipitators.

[0038] Because of the internal switch in the filter handle, the contacts between the connectors are short-circuited or de-short-circuited, thereby preventing safety accidents that may occur when disconnecting the electrostatic precipitator.

[0039] The effects of this invention are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned from the description of the claims. Attached Figure Description

[0091] The outer casing 10 includes: an upper outer casing 12 that forms a space inside; and a lower outer casing 14 disposed below the upper outer casing 12, forming an intake port 16a and an exhaust port 16b.

[0092] Reference Figure 3 An air guide 38 is provided on the upper housing 12 to guide the air flowing through the fan 30 to the outlet 16b.

[0093] The lower housing 14 has an intake port 16a equipped with an intake panel 16. A pre-filter 34 and an electrostatic precipitator 50 are arranged on the upper side of the intake panel 16. A filter housing 20 for mounting the electrostatic precipitator 50 is arranged on the upper side of the lower housing 14.

[0094] The blade module 40 may include an outer blade 42 and an inner blade 44. The outer blade 42 and the inner blade 44 can rotate in conjunction with each other. The outer blade 42 and the inner blade 44 can guide the air discharged from the outlet 16b in a horizontal or vertical direction. The blade module 40 may be configured with vertical blades (not shown) that guide the air discharged from the outlet 16b in a left-right direction.

[0095] Inside the housing 10, a drain pan 36 can be configured to temporarily store the condensate generated by the heat exchanger 32.

[0096] <Electrostatic Precipitation Device>

[0097] The following is for reference Figures 4 to 29This describes an embodiment of the electrostatic precipitator 50 of the present invention. Figures 4 to 25 , Figures 28 to 29 The description is based on the length direction (l+, l-), width direction (w+, w-), and height direction (h+, h-) of the electrostatic precipitator.

[0098] The electrostatic precipitator 50 includes at least one electrostatic filter 100 for collecting dust particles from the air.

[0099] The electrostatic precipitator filter 100 may include a first sidewall 104 disposed on one side thereon and a second sidewall 106 disposed in the opposite direction to the first sidewall 104. A first engagement protrusion 104a protruding outward from the first sidewall 104 is disposed on the first sidewall 104. A second engagement groove 106b corresponding to the first engagement protrusion 104a is formed on the second sidewall 106.

[0100] A first engagement groove 104b recessed inward is formed in the first sidewall 104. A second engagement protrusion 106a, having the size to be inserted into the first engagement groove 104b and protruding outward, is disposed in the second sidewall 106.

[0101] The first engaging protrusion 104a and the first engaging groove 104b are spaced apart from each other on the first sidewall 104 in the front-back direction. The second engaging protrusion 106a and the second engaging groove 106b are spaced apart from each other on the second sidewall 106 in the front-back direction. The first engaging protrusion 104a and the second engaging protrusion 106a are arranged in opposite directions in the front-back direction.

[0102] The first engagement protrusion 104a has a structure for insertion into the second engagement groove 106b. The first engagement groove 104b has a structure for insertion of the second engagement protrusion 106a.

[0103] The electrostatic precipitator 100 includes a button for securing the electrostatic precipitator 100. The button includes: a first button protrusion 162 protruding upward from the upper surface of the electrostatic precipitator 100; a restoration plate 166 restoring the configuration of the first button protrusion 162; and a second button protrusion 164 configured to protrude from either a first engagement protrusion 104a or a second engagement protrusion 106a and move together with the first button protrusion 162.

[0104] The electrostatic precipitator 50 may include at least one filter handle disposed on one side of the electrostatic precipitator filter 100, securing the electrostatic precipitator filter 100 to the housing 10. The filter handle is connected to the electrostatic precipitator filter 100 and has a structure for being fixed to the housing.

[0105] As an example, refer to Figures 4 to 7The electrostatic precipitator 50 may include: a first filter handle 200a, disposed on one side of the electrostatic precipitator filter 100, for securing the electrostatic precipitator filter 100 to the housing 10; and a second filter handle 200b, disposed on the other side of the electrostatic precipitator filter 100, for securing the electrostatic precipitator filter 100 to the housing 10. The filter handles may also have other forms for securing the electrostatic precipitator filter 100 to the housing. Alternatively, the electrostatic precipitator filter 100 may be directly mounted to the housing 10 without a filter handle.

[0106] The first sidewall 104 of the electrostatic precipitator filter 100 has a structure that engages with the first filter handle 200a, and the second sidewall 106 of the electrostatic precipitator filter 100 has a structure that engages with the second filter handle 200b. The first sidewall 104 of the electrostatic precipitator filter 100 has a corresponding structure to the second sidewall 106, thereby allowing adjacent electrostatic precipitators 100 to be arranged. That is, a plurality of electrostatic precipitators 100a and 100b can be arranged between the first filter handle 200a and the second filter handle 200b.

[0107] Reference Figures 4 to 6 A first electrostatic precipitator 100a and a second electrostatic precipitator 100b may be disposed between the first filter handle 200a and the second filter handle 200b. The first electrostatic precipitator 100a and the second electrostatic precipitator 100b may be formed to have the same shape and the same size. The first electrostatic precipitator 100a and the second electrostatic precipitator 100b may have a structure in which they are joined together between the first filter handle 200a and the second filter handle 200b.

[0108] The first sidewall 104 of the electrostatic precipitator filter 100 may have the same structure as one sidewall of the second filter handle 200b. The second sidewall 106 of the electrostatic precipitator filter 100 may have the same structure as one sidewall of the first filter handle 200a.

[0109] <Electrostatic Filter>

[0110] Reference Figure 9 The electrostatic precipitator filter 100 includes: a housing 102 forming the exterior and having an opening in the height direction of the electrostatic precipitator filter to allow airflow; a plurality of electrostatic precipitator membranes 120 disposed separately from each other inside the housing 102 to collect dust particles in the air; and membrane retainers 130a and 130b disposed inside the housing 102 such that the plurality of electrostatic precipitator membranes 120 are respectively disposed separately from each other.

[0111] Reference Figure 9The electrostatic precipitator 100 also includes buttons 160a, 160b for maintaining or deactivating its engagement with an adjacent electrostatic precipitator 100, a first filter handle 200a, or a second filter handle 200b. (See reference...) Figure 9 Buttons 160a and 160b are configured to protrude upwards toward the upper side of housing 102. (Refer to...) Figure 9 The electrostatic precipitator filter 100 includes a first button 160a disposed on one side of the housing 102 and a second button 160b disposed on the other side of the housing 102.

[0112] The first button 160a and the second button 160b each include: a first button protrusion 162 protruding toward the upper wall of the housing 102; a restoration plate 166 restoring the configuration of the first button protrusion 162; and a second button protrusion 164 that moves together with the first button protrusion 162. When the first button protrusion 162 moves vertically, the position of the second button protrusion 164 also changes. The restoration plate 166 can be disposed inside the housing 102 and restore the configuration of the first button protrusion 162. Therefore, the configuration of the first button protrusion 162 can be maintained without applying additional external force. When no additional external force is applied to the first button protrusion 162, the first button protrusion 162 can be configured to protrude upward from the upper surface of the housing 102. The second button protrusion 164 is disposed on the connecting protrusions 104a and 106a of the housing 102 described below. When the engagement protrusions 104a and 106a are inserted into the engagement grooves 104b and 106b, the second button protrusion 164 can be inserted into the fixing grooves 104c and 106c formed in the engagement grooves 104b and 106b. That is, the second button protrusion 164 can keep the electrostatic precipitator 100 engaged with another electrostatic precipitator 100. In addition, the second button protrusion 164 can keep the electrostatic precipitator 100 engaged with the first filter handle 200a or the second filter handle 200b.

[0113] Reference Figure 9 The electrostatic precipitator filter 100 may include: a contact support 140 for connecting a plurality of electrodes spaced apart from each other; and a support holder 150 for supporting the contact support 140.

[0114] The housing 102 forms flow holes 103c for airflow. The housing 102 also forms spaces inside for arranging a plurality of electrostatic precipitators 120. The plurality of electrostatic precipitators 120 can be held in a state of being arranged at predetermined intervals inside the housing 102 by membrane holders 130a and 130b.

[0115] The length of the first exposed end 126a or the second exposed end 126b protruding from the membrane retainer 130a, 130b is longer than the interval between the membrane retainer 130a, 130b and the contact support 140a, 140b.

[0116] Reference Figure 10 When viewed from the side, the housing 102 can have a trapezoidal shape in which its length in the front-back direction becomes narrower as it gets closer to the top.

[0117] Reference Figures 7 to 8 The housing 102 includes a first sidewall 104 for mounting a first filter handle 200a and a second sidewall 106 for mounting a second filter handle 200b. Another electrostatic precipitator filter 100 may be mounted on either the first sidewall 104 or the second sidewall 106 of the housing 102.

[0118] Reference Figures 7 to 8 A first sidewall 104 is disposed on the left side of the housing 102, and a second sidewall 106 is disposed on the right side. The first sidewall 104 and the second sidewall 106 are disposed in opposite directions to each other.

[0119] The first sidewall 104 is provided with a first engagement protrusion 104a protruding outward and a first engagement groove 104b forming a groove inward. The second sidewall 106 is provided with a second engagement groove 106b forming a groove inward and a second engagement protrusion 106a protruding outward.

[0120] A first engaging protrusion 104a is disposed behind the first sidewall 104, and a first engaging groove 104b is disposed in front of the first sidewall 104. A second engaging groove 106b is disposed behind the second sidewall 106, and a second engaging protrusion 106a is disposed in front of the second sidewall 106.

[0121] A first filter handle 200a or a second sidewall 106 of another electrostatic precipitator filter 100 may be connected to the first sidewall 104. A second filter handle 200b or a first sidewall 104 of another electrostatic precipitator filter 100 may be connected to the second sidewall 106. Here, in addition to the state of structural connection between a plurality of electrostatic precipitators filter 100, the meaning of connection may also include the state of electrical connection.

[0122] The electrostatic precipitator 100 and the first filter handle 200a or the second filter handle 200b can move in the front-back direction and engage or disengage in a sliding manner. The electrostatic precipitator 100 and another electrostatic precipitator 100 can move in the front-back direction and engage or disengage in a sliding manner.

[0123] Unlike the figures shown, the electrostatic precipitator 100 and the first filter handle 200a or the second filter handle 200b can also be engaged or disengaged in a manner other than sliding. That is, the electrostatic precipitator 100 and the first filter handle 200a or the second filter handle 200b can be engaged by inserting them in the vertical or horizontal direction.

[0124] Similarly, electrostatic precipitator 100 and another electrostatic precipitator 100 can be joined or disjointed in a manner other than sliding. The first joining protrusion 104a has a shape corresponding to the second joining groove 106b. The second joining protrusion 106a has a shape corresponding to the first joining groove 104b. Therefore, a plurality of electrostatic precipitators 100 joined together can be arranged in a left-right direction.

[0125] The first connecting protrusion 104a has a structure that protrudes from the first sidewall 104 in a "T" shape. The second connecting groove 106b has a groove structure that recesses from the second sidewall 106 in a "T" shape.

[0126] The second connecting protrusion 106a has a structure that protrudes from the second sidewall 106 in a "T" shape. The first connecting groove 104b has a groove structure that recesses from the first sidewall 104 in a "T" shape.

[0127] Reference Figures 7 to 8 The first engaging protrusion 104a and the second engaging protrusion 106a extend in the front-rear direction. The first engaging groove 104b and the second engaging groove 106b extend in the front-rear direction. Therefore, the electrostatic precipitator 100 can be slidably engaged with another electrostatic precipitator 100. The electrostatic precipitator 100 can be slidably engaged with the first filter handle 200a or the second filter handle 200b.

[0128] A first fixing groove 104c formed in the vertical direction can be formed on one side of the first mating groove 104b. A second fixing groove 106c formed in the vertical direction can be formed on one side of the second mating groove 106b.

[0129] A portion of a second button 160b, configured on a second engagement protrusion 106a of another electrostatic precipitator 100, can be inserted into the first engagement groove 104b. When the user presses the second button 160b, a portion of the second button 160b is pulled out from the first engagement groove 104b, and the electrostatic precipitator 100 can slide in the back-and-forth direction.

[0130] A portion of a first button 160a, configured on a first engagement protrusion 104a of another electrostatic precipitator 100, can be inserted into the second engagement groove 106b. When the user presses the first button 160a, a portion of the first button 160a is pulled out from the second engagement groove 106b, and the electrostatic precipitator 100 can slide in the back-and-forth direction.

[0131] The housing 102 has inlet holes 108a and 110a for inserting the contact bracket 140 and the bracket holder 150. The contact bracket 140 and the bracket holder 150 can be inserted through the inlet holes 108a and 110a.

[0132] A first inlet hole 108a is formed on the first sidewall 104 of the housing 102. The first inlet hole 108a is located in front of the first engaging protrusion 104a. A second inlet hole 110a is formed on the second sidewall 106 of the housing 102. The second inlet hole 110a is located behind the second engaging protrusion 106a. The contact bracket 140 and the bracket holder 150 are mounted to the housing 102 through the first inlet hole 108a or the second inlet hole 110a.

[0133] A first lead-out hole 108b is formed on the second sidewall 106 of the housing 102, and one end of the contact bracket 140, which is inserted and installed through the first lead-in hole 108a, protrudes through the first lead-out hole 108b. A second lead-out hole 110b is formed on the first sidewall 104 of the housing 102, and one end of the contact bracket 140, which is inserted and installed through the second lead-in hole 110a, protrudes through the second lead-out hole 110b.

[0134] Reference Figure 10 The first inlet hole 108a is formed on one side of the first engagement protrusion 104a, and the first outlet hole 108b is formed on one side of the first engagement groove 104b.

[0135] The housing 102 has a first contact space 103a for arranging a contact support 140 inserted through a first inlet hole 108a, and a second contact space 103b for arranging a contact support 140 inserted through a second inlet hole 110a. The first contact space 103a and the second contact space 103b are arranged in different directions relative to each other. (Refer to...) Figure 17 The first contact space 103a is positioned further forward than the plurality of electrostatic precipitators 120, and the second contact space 103b is positioned further backward than the plurality of electrostatic precipitators 120.

[0136] The first contact space 103a may be provided with a first exposed end 126a of each of a plurality of first electrostatic precipitators 120a as described below. The second contact space 103b may be provided with a second exposed end 126b of each of a plurality of second electrostatic precipitators 120b as described below.

[0137] Reference Figure 9 The housing 102 may include an upper housing 102a and a lower housing 102b. The upper housing 102a and the lower housing 102b may be joined together to form a space on the inside for arranging a plurality of electrostatic precipitators 120. When the upper housing 102a and the lower housing 102b are joined, joint protrusions and joint grooves are formed on the side walls of the housing.

[0138] A plurality of electrostatic precipitators 120 may be disposed inside the housing 102. Each of the plurality of electrostatic precipitators 120 includes: an electrode 124 forming a conductive layer through which current flows; and a membrane 122 fixing the arrangement of the electrode 124 and forming an insulating layer. The interior of the housing 102 may include spacers 128 disposed between the plurality of electrostatic precipitators 120 and spaced apart from each other.

[0139] Reference Figure 11 Electrode 124 can be disposed inside membrane 122. Electrode 124 can be configured to be covered by membrane 122 so that the area through which current flows is not exposed to the outside. (Refer to...) Figure 11 Electrode 124 may include an exposed end 126 configured to protrude from membrane 122 from one end in the front-rear direction. The exposed end 126 is formed to be ultrathin, thereby being deformable in the left-right direction. The exposed end 126 is formed to be less than a predetermined thickness, thereby having a structure that is deformable in the direction of insertion into contact supports 140a, 140b.

[0140] The plurality of electrostatic precipitators 120 may include a first electrostatic precipitator 120a connected to a high-voltage generating unit (not shown) and a second electrostatic precipitator 120b connected to a grounding unit (not shown). The plurality of first electrostatic precipitators 120a and the plurality of second electrostatic precipitators 120b may be configured to alternate with each other. The first electrostatic precipitators 120a and the second electrostatic precipitators 120b may have the same shape.

[0141] The first electrostatic precipitator 120a and the second electrostatic precipitator 120b are respectively configured to have exposed ends in different directions. That is, referring to... Figure 17 The first exposed end 126a of the first electrostatic precipitator 120a is disposed in the first contact space 103a. The second exposed end 126b of the second electrostatic precipitator 120b is disposed in the second contact space 103b.

[0142] The electrostatic precipitator filter 100 includes a pair of contact supports 140 and a pair of support holders 150. The electrostatic precipitator filter 100 includes a first contact support 140a and a first support holder 150a disposed in a first contact space 103a. The electrostatic precipitator filter 100 includes a second contact support 140b and a second support holder 150b disposed in a second contact space 103b.

[0143] The first contact support 140a and the second contact support 140b may have the same shape. The first support holder 150a and the second support holder 150b may also have the same shape. Referring to the following... Figures 13 to 15 This section explains the configuration of the contact support 140 and the support holder 150. The structure of the contact support 140 described herein can be applied to the first contact support 140a and the second contact support 140b, respectively. Similarly, the support holder 150 described above can also be applied to the first support holder 150a and the second support holder 150b, respectively.

[0144] The contact support 140 may include: a contact body 142, which contacts a plurality of first electrostatic precipitators 120a or a plurality of second electrostatic precipitators 120b respectively; a first contact end 144, which is disposed on one side of the contact body 142 and is configured to be exposed through a first lead-out hole 108b or a second lead-out hole 110b; and a second contact end 146, which is disposed on the other side of the contact body 142 and is configured to be exposed through a first lead-in hole 108a or a second lead-in hole 110a.

[0145] The contact body 142 has a structure extending along the length direction (l+, l-) of the electrostatic precipitator filter inside the housing 102. The contact body 142 is configured to intersect with a plurality of electrostatic precipitators 120 disposed inside the housing 102. The contact body 142 is also configured to be inclined relative to the plurality of electrostatic precipitators 120. (Refer to...) Figure 17 The contact body 142 can be configured to be perpendicular to a plurality of electrostatic precipitators 120.

[0146] The contact body 142 is disposed on one side of the retainer body 152 of the retainer 150 described below. With the contact support 140 mounted to the retainer 150, both ends of the contact support 140 are fixed to the retainer 150. The state in which the contact support 140 is mounted to the retainer 150 means that the first contact end 144 is fixed to the first spacer protrusion 154 of the retainer 150, and the second contact end 146 is fixed to the second spacer protrusion 156 of the retainer 150, allowing the contact support 140 and the retainer 150 to move together. Therefore, with the contact support 140 mounted to the retainer 150, the contact support 140 and the retainer 150 can be inserted into the first inlet hole 108a or the second inlet hole 110a of the housing 102.

[0147] The first contact end 144 and the second contact end 146 can extend away from the contact body 142 from a position spaced at a predetermined interval from the contact body 142 toward the direction in which the support holder 150 is disposed.

[0148] Reference Figures 13 to 15 The first contact end 144 and the second contact end 146 can extend along the length direction (l+, l-) of the electrostatic precipitator filter from a position spaced outward from the contact body 142. Here, the direction in which the contact body 142 is disposed can be set as the inward direction, and the direction in which the holder body 152, in which the bracket holder 150 is disposed, is set as the outward direction.

[0149] The first contact end 144 and the second contact end 146 extend in different directions relative to the contact body 142.

[0150] The first contact end 144 bends outward from the contact body 142 and extends in the opposite direction to the contact body 142. The first contact end 144 extends in the opposite direction to the contact body 142 from a position spaced outward from the contact body 142.

[0151] Reference Figure 15 The first spacer protrusion 154 is disposed on one side of the contact body 142 in the direction in which the contact body 142 extends. Therefore, the first contact end 144 connected to the contact body 142 can be bent along the periphery of the first spacer protrusion 154 and extend along the length direction (l+, l-) of the electrostatic precipitator filter. Due to the structure of the first spacer protrusion 154 and the first contact end 144, the movement of the contact support 140 in the length direction (l+, l-) of the electrostatic precipitator filter or the width direction (w+, w-) of the electrostatic precipitator device can be restricted.

[0152] The second contact end 146 is disposed on the other side of the second spaced protrusion 156. The second contact end 146 bends outward from the contact body 142 and extends in the opposite direction to the contact body 142. The second contact end 146 extends in the opposite direction to the contact body 142 from a position spaced a predetermined distance from the outward direction of the contact body 142. (Refer to...) Figure 15 The second spacer protrusion 156 is disposed on one side of the contact body 142 in the direction in which the contact body 142 extends. Therefore, the second contact end 146, connected to the other side of the contact body 142, can be bent along the periphery of the second spacer protrusion 156 and extend along the length direction (l+, l-) of the electrostatic precipitator filter. Due to the structure of the second spacer protrusion 156 and the second contact end 146, the movement of the contact support 140 in the length direction (l+, l-) of the electrostatic precipitator filter or the width direction (w+, w-) of the electrostatic precipitator device can be restricted.

[0153] The length of the second contact end 146 may be longer than the length of the first contact end 144. The first contact end 144 has a structure extending to a portion of the first spacer protrusion 154 formed on the support holder 150 described below. The second contact end 146 has a structure that extends longer than the portion formed on the second spacer protrusion 156.

[0154] The second contact end 146 may have a structure that bends inward from the region passing through the second spaced protrusion 156.

[0155] With the contact bracket 140 installed in the housing 102, the contact body 142 is configured to contact a plurality of electrostatic precipitators 120 respectively. Here, the state in which the contact bracket 140 is installed in the housing 102 can mean that the first contact end 144 of the contact bracket 140 is configured to pass through the first lead-out hole 108b or the second lead-out hole 110b, and the contact bracket 140 is fixed to the housing 102.

[0156] Reference Figure 18 With the contact bracket 140 installed in the housing 102, the first contact end 144 is configured to protrude to the outside of the housing 102 through the first lead-out hole 108b or the second lead-out hole 110b. Additionally, the second contact end 146 protrudes to the outside of the housing 102 through the first lead-in hole 108a or the second lead-in hole 110a.

[0157] The length of the second contact end 146 can be longer than the length of the first contact end 144. The second contact end 146 can have a structure that extends along the length direction (l+, l-) of the electrostatic precipitator via the second spaced protrusion 156.

[0158] The bracket retainer 150 includes: a retainer body 152 disposed on one side of the contact body 142 of the contact bracket 140, supporting one side of the contact body 142; a first spacer protrusion 154 disposed on one end of the retainer body 152, fixing one end of the contact bracket 140; a second spacer protrusion 156 disposed on the other end of the retainer body 152, fixing the other end of the contact bracket 140; a retainer clamping member 158 extending from the other end of the retainer body 152; and a fastening portion 159 for securing the bracket retainer 150 to the housing 102.

[0159] The retainer body 152 can be disposed on one side of the contact body 142, supporting the shape of the contact body 142. The contact body 142 has a thin plate-shaped structure, thus it can be easily deformed. The retainer body 152 is disposed on the outer side of the contact body 142 and configured to contact the contact body 142. The retainer body 152 contacts the plurality of membranes 122, which can prevent deformation of the contact body 142 inserted into the housing 102.

[0160] Reference Figure 14 The retainer body 152 includes: a first body 152a extending along the length direction (l+, l-) of the electrostatic precipitator filter; a second body 152b disposed side-by-side with the first body 152a at a position spaced apart from it; and a connecting rib 152c connecting the first body 152a and the second body 152b. The structure of connecting the first body 152a and the second body 152b via the connecting rib 152c enhances the rigidity of the retainer body 152.

[0161] Reference Figure 14 The first body 152a is configured to contact the contact body 142 on one side. The second body 152b may be configured to be spaced outward from the first body 152a. The retainer body 152 may include a plurality of connecting ribs 152c. The plurality of connecting ribs 152c are spaced apart along the length direction (l+, l-) of the electrostatic precipitator filter.

[0162] A first spacer protrusion 154 is disposed on one side of the first body 152a. The first spacer protrusion 154 is configured to be spaced apart from the first body 152a. A first contact end 144 extending from the contact body 142 may be disposed between the first spacer protrusion 154 and the first body 152a.

[0163] The second spacer protrusion 156 is disposed on the other side of the first body 152a. The second spacer protrusion 156 is disposed in the opposite direction of the first spacer protrusion 154 with reference to the retainer body 152. The second spacer protrusion 156 is configured to be spaced apart from the first body 152a. A second contact end 146 extending from the contact body 142 may be disposed between the second spacer protrusion 156 and the first body 152a.

[0164] The retainer clamping member 158 extends from the second body 152b along the length direction (l+, l-) of the electrostatic precipitator filter. The retainer clamping member 158 may be configured to be spaced outward from the second spaced protrusion 156. The second contact end 146 may be disposed between the retainer clamping member 158 and the second spaced protrusion 156.

[0165] The retainer clamp 158 may have a structure that protrudes further outward than the second body 152b. Therefore, when the contact bracket 140 and the bracket retainer 150 are inserted into the housing 102, the retainer clamp 158 contacts the housing 102. When the retainer clamp 158 contacts one side of the housing 102, it can restrict the movement of the bracket retainer 150 in the direction of insertion into the housing 102.

[0166] The fastening part 159 extends downward from the retainer clamp 158 and secures the bracket retainer 150 to one side of the housing 102. The fastening part 159 can be secured to the housing 102 using an additional fastening screw (not shown). With the contact bracket 140 and bracket retainer 150 installed in the housing 102, the fastening screw can be used to secure the bracket retainer 150 to the housing 102. The state in which the contact bracket 140 and bracket retainer 150 are installed in the housing 102 can mean that the contact bracket 140 and bracket retainer 150 cannot be further inserted into the housing 102.

[0167] Reference Figures 17 to 18 A first contact space 103a for configuring the first contact bracket 140a and the first bracket holder 150a, and a second contact space 103b for configuring the second contact bracket 140b and the second bracket holder 150b are formed on the inner side of the housing 102.

[0168] The first contact bracket 140a and the first bracket holder 150a can be inserted into the first inlet hole 108a formed in the housing 102. The first contact bracket 140a and the first bracket holder 150a can be slidably coupled to the housing 102. When the first contact bracket 140a and the first bracket holder 150a are inserted into the inner side of the housing 102, the first contact bracket 140a and the first exposed end 126a of the first electrostatic precipitator 120a can contact each other. (Refer to...) Figure 11The shape of the first exposed end 126a can be changed by the first contact support 140a. (Refer to...) Figure 17 The first exposed end 126a can deform in the direction of insertion into the first contact bracket 140a. The first exposed end 126a is configured to contact the first contact bracket 140a in a state where it has been shaped by the first contact bracket 140a.

[0169] The second contact bracket 140b and the second bracket holder 150b can also contact the second exposed end 126b of the second electrostatic precipitator 120 disposed in the second contact space 103b in the same manner.

[0170] Reference Figure 18 With the first contact bracket 140a mounted to the housing 102, the first contact end 144 of the first contact bracket 140a is configured to protrude from the first lead-out hole 108b. With the first contact bracket 140a mounted to the housing 102, the first contact end 144 of the first contact bracket 140a is configured not to obstruct movement into the configuration of the second mating groove 106b. (Refer to...) Figure 18 With the first contact bracket 140a mounted to the housing 102, the first contact end 144 of the first contact bracket 140a is configured not to protrude further than the second mating groove 106b formed in the second sidewall 106. (Refer to...) Figure 18 With the first contact bracket 140a installed in the housing 102, the first contact end 144 of the first contact bracket 140a is configured not to protrude more than the wall surface forming the second engagement groove 106b in the length direction (l+, l-) of the electrostatic precipitator.

[0171] Reference Figure 18 With the first support holder 150a installed in the housing 102, the first spacer protrusion 154 of the first support holder 150a is configured to protrude outward toward the first outlet hole 108b. (Refer to...) Figure 18 With the first support holder 150a installed in the housing 102, the first spacer protrusion 154 of the first support holder 150a is configured not to protrude more than the wall forming the second engagement groove 106b in the length direction (l+, l-) of the electrostatic precipitator.

[0172] Reference Figure 18 With the first contact bracket 140a installed in the housing 102, the second contact end 146 of the first contact bracket 140a is configured to protrude from the first inlet hole 108a toward the outside of the housing 102. (Refer to...) Figure 18With the first contact bracket 140a installed in the housing 102, the second contact end 146 of the first contact bracket 140a is configured not to protrude more than the first engagement protrusion 104a formed on the first sidewall 104 in the length direction (l+, l-) of the electrostatic precipitator.

[0173] Reference Figure 18 With the first bracket holder 150a installed in the housing 102, the second spacer protrusion 156 of the first bracket holder 150a is configured to protrude outwards from the first inlet hole 108a. (Refer to...) Figure 18 With the first support holder 150a installed in the housing 102, the second spacer protrusion 156 of the first support holder 150a is configured not to protrude more than the wall surface forming the second connecting protrusion 106a in the length direction (l+, l-) of the electrostatic precipitator.

[0174] Reference Figure 18 The second contact bracket 140b and the second bracket holder 150b can also be configured in the same way.

[0175] <First filter handle and second filter handle>

[0176] Reference Figures 4 to 6 The electrostatic precipitator 50 includes a first filter handle 200a and a second filter handle 200b. The first filter handle 200a and the second filter handle 200b may have a symmetrical structure in the left-right direction. The first filter handle 200a and the second filter handle 200b may include the same configuration. However, a portion of the configuration included in each of the first filter handle 200a and the second filter handle 200b may be configured differently.

[0177] The following is for reference Figures 19 to 22 This explains the structure of the second filter handle 200b.

[0178] The second filter handle 200b includes: an inner cover 202 forming a wall opposite to the electrostatic precipitator filter 100; an outer cover 210 disposed on one side of the inner cover 202 and having a fixing protrusion 214 that snaps into the housing 10; a handle button 240 for fixing the second filter handle 200b to or releasing it from the housing 10; a first connector 220 disposed on one side of a corresponding protrusion 204a formed on one side of the inner cover 202 and electrically connected to the electrostatic precipitator membrane 120; a second connector 230 disposed on one side of a corresponding groove 204b formed on the other side of the inner cover 202 and electrically connected to the electrostatic precipitator membrane 120; and a switch 250 for short-circuiting or de-short-circuiting the first connector 220 and the second connector 230.

[0179] The inner cover 202 includes a corresponding wall 204 opposite to the electrostatic precipitator 100. Corresponding protrusions 204a are formed on the corresponding wall 204 of the inner cover 202, which are inserted into the mating grooves 104b and 106b of the electrostatic precipitator 100, and corresponding grooves 204b into which the mating protrusions 104a and 106a of the power supply dust collector 100 are inserted.

[0180] The inner cover 202 has a first connector groove 206a that forms a space to accommodate a first connector 220, a second connector groove 206b that forms a space to accommodate a second connector 230, and a switch groove 206c that forms a space to accommodate a switch 250.

[0181] The outer cover 210 can be configured to surround the portion of the inner cover 202 except for the corresponding wall 204. The outer cover 210 and the inner cover 202 can be joined together. The outer cover 210 and the inner cover 202 can be joined together by an additional fastening device.

[0182] The outer cover 210 may include an outer wall 212 opposite to the corresponding wall 204 of the inner cover 202. The outer wall 212 may be a wall surface configured to face the filter housing 20 on which the filter handles 200a, 200b are mounted. The outer wall 212 may be provided with a fixing protrusion 214 for securing the filter handles 200a, 200b to the filter housing 20.

[0183] The fixed protrusion 214 can also be configured to be spaced apart from the handle button 240 along the width direction (w+, w-) of the electrostatic precipitator.

[0184] The upper surface of the outer cover 210 has a first connector hole 216a, which exposes a portion of the first connector 220 as described below; a second connector hole 216b, which exposes a portion of the second connector 230 as described below; and a switch hole 216c, which exposes a portion of the switch 250 as described below.

[0185] A first exposed plate 224 of a first connector 220, as described below, is disposed in the first connector hole 216a. A second exposed plate 234 of a second connector 230, as described below, is disposed in the second connector hole 216b. (Refer to...) Figures 26 to 27 When the electrostatic precipitator 50 is installed on the filter housing 20, the first connector 220 can contact the first contact switch 22 disposed on the filter housing 20. (Refer to...) Figures 26 to 27 When the electrostatic precipitator 50 is installed on the filter housing 20, the second connector 230 can contact the second contact switch 24 disposed on the filter housing 20.

[0186] A portion of the switch 250 can be configured in the switch hole 216c. Therefore, when the electrostatic precipitator 50 is installed onto the filter housing 20, the shorting plate 254 of the switch 250 can be moved downwards via the pressing protrusion 26 of the filter housing 20. In this case, the downward movement of the shorting plate 254 disengages it from the first connector 220 and the second connector 230.

[0187] The outer cover 210 may have: a first button hole 218a, formed on the lower surface of the outer cover 210, exposing a portion of the handle button 240; and a second button hole 218b, formed on the upper surface of the outer cover 210, exposing the other components of the handle button 240.

[0188] The first button hole 218a may be equipped with a pressing body 244 of the handle button 240 as described below. The second button hole 218b may be equipped with a hook 242 of the handle button 240 as described below.

[0189] The handle button 240 includes: a hook 242 for fixing the filter handles 200a and 200b to one side of the filter housing 20; a pressing body 244 for changing its configuration under external pressure to release the hook 242; and an elastic body 246 for restoring the pressing body 244 to its original configuration when no external force is applied to it.

[0190] The pressing body 244 and the hook 242 can be formed as one unit and move together. The pressing body 244 and the hook 242 can have a structure that moves along the width direction (w+, w-) of the electrostatic precipitator.

[0191] When no additional external force is applied to the pressing body 244, the configuration of the pressing body 244 and the hook 242 can be determined by the elastic body 246. That is, the elastic body 246 can be configured on one side of the outer cover 210 to keep the configuration of the pressing body 244 and the hook 242 constant. When only the elastic body 246 applies force to the pressing body 244, the hook 242 can be configured to hook onto one side of the filter housing 20. Therefore, the electrostatic precipitator 50 can be configured to be fixed inside the filter housing 20.

[0192] However, the configuration of the hook 242 can be changed when the user or others press the pressing body 244. When pressure is applied to the pressing body 244 in the opposite direction to the elastic force of the elastic body 246, the hook 242 can be released. Therefore, one side of the electrostatic precipitator 50 can be detached from the filter housing 20.

[0193] The first connector 220 and the second connector 230 can electrically connect the electrostatic precipitator 100 to a high-voltage section or a grounded section. The first connector 220 and the second connector 230 can be configured in opposite directions relative to each other with respect to the switch 250. The ends of each of the first connector 220 and the second connector 230 can be configured to contact the shorting plate 254 of the switch 250.

[0194] The first connector 220 includes: a first connecting plate 222 electrically connected to the electrostatic precipitator membrane 120 of the electrostatic precipitator filter 100; a first exposed plate 224 disposed in a first connector hole 216a formed in the outer cover 210; a first contact plate 226 disposed in contact with the switch 250; and a first fastening plate 228 securing the first connector 220 to one side of the inner cover 202.

[0195] The first connecting plate 222 is disposed on one side of the corresponding protrusion 204a. (Refer to...) Figure 21 The first connecting plate 222 is configured to protrude from the sidewall formed by the corresponding protrusion 204a.

[0196] The first fastening plate 228 can be secured to the inner cover 202 using an additional fastening screw 228a.

[0198] The second connecting plate 232 is disposed on one side of the corresponding groove 204b. The second connecting plate 232 is configured not to protrude from the side wall formed in the corresponding groove 204b. The second fastening plate 238 can be secured to the inner cover 202 using an additional fastening screw 238a.

[0199] The switch 250 includes: a switch body 252; a short-circuit plate 254 connecting a first connector 220 and a second connector 230; and an elastomer 256 disposed inside the switch body 252 to restore the configuration of the short-circuit plate 254.

[0200] The short-circuit plate 254 has a structure that allows it to move along the height direction (h+, h-) of the electrostatic precipitator. The elastomer 256 applies pressure to the short-circuit plate 254 in the downward direction. Therefore, without applying any additional external force to the short-circuit plate 254, the short-circuit plate 254 can be fixed in its downward position solely by the elastic force of the elastomer 256.

[0201] When the shorting plate 254 is fixed downward by the elastic body 256, it can contact the first connector 220 and the second connector 230 respectively. When the configuration of the shorting plate 254 is moved upward by an external force, the contact between the shorting plate 254 and the first connector 220 and the second connector 230 can be released respectively.

[0202] The first filter handle 200a may include the same configuration as the second filter handle 200b. However, the configurations of the components included in the first filter handle 200a and the components included in the second filter handle 200b may differ partially.

[0203] Reference Figure 19 The second filter handle 200b has a corresponding protrusion 204a at its front and a corresponding groove 204b at its rear. Additionally, the right side of the second filter handle 200b has a corresponding wall 204 opposite to the electrostatic precipitator 100. A first connector 220 is located on one side of the corresponding protrusion 204a at the front of the second filter handle 200b, and a second connector 230, located on one side of the corresponding groove 204b, is positioned further rearward than the first connector 220.

Additionally, a corresponding wall 204 opposite the electrostatic precipitator 100 is disposed on the left side of the first filter handle 200a. A second connector 230 is disposed in front of the first filter handle 200a on one side of the corresponding groove 204b, and a first connector 220 is disposed in front of the first filter handle 200a on one side of the corresponding protrusion 204a, positioned further rearward than the second connector 230.
