Description

Technical Field

[0001] This utility model relates to an indoor unit of an air conditioner, and more specifically, to an indoor unit of a vertical air conditioner. Background Technology

[0002] Typically, an air conditioner has electrical devices and various electrical components that operate by a power source. Therefore, an air conditioner is equipped with a large number of connecting wires to connect the power source and the various electrical components.

[0003] As mentioned above, with numerous electrical components and connecting wires inside the air conditioner, unnecessary interference between these wires may cause short circuits or other leakage problems. To prevent such problems, careful wiring design is required to ensure that the wiring inside the air conditioner does not cause interference between components as much as possible.

[0004] In particular, in the indoor unit of a vertical air conditioner that consists of an upper and lower casing, numerous connecting wires are arranged for the electrical components in both casings. Therefore, in indoor units configured to allow the front-mounted air blower to open and close to clean the air blower located in the upper casing, there is a possibility that movement of the upper casing could cause the connecting wires to move and break. If such a connecting wire breaks, the external power supply cannot smoothly supply power to the electrical components of the indoor unit, causing the indoor unit to stop. Utility Model Content

[0123] The third air supply module 230 has the same configuration as the first air supply module 210. Therefore, the description of the third air supply module 230 can refer to the aforementioned content of the first air supply module 210.

[0124] A portion of the air passing through the heat exchanger 3100 moves toward the inside of the third air supply housing 233. Furthermore, the air expelled to the outside of the third air supply housing 233 by the operation of the third air supply fan 232 can flow toward the side outlet 2111 and be expelled to the outside.

[0125] Here, the air supply fans 212, 222, and 232 can be centrifugal fans that allow air to flow in axially and be discharged radially through the side outlets 2111.

[0126] Centrifugal fans can have mechanical characteristics such as large air volume and high static pressure performance.

[0127] The air supply module section 2100 may only have a first air supply module 210 and a second air supply module 220, or it may include various modified embodiments where an air supply module is also included on the lower side of the third air supply module 230, as needed.

[0128] The air supply module 2100 of this utility model embodiment may have a partition wall 214, which includes a first partition wall 214a, a second partition wall 214b and a third partition wall 214c.

[0129] The first partition wall 214a can be formed between the first air supply module 210 and the second air supply module 220 to separate the first air supply module 210 and the second air supply module 220. The first partition wall 214a can be arranged horizontally between the first air supply module 210 and the second air supply module 220.

[0130] The first partition wall 214a can contact the first corresponding partition wall 215a of the corresponding protective housing 2300, thereby allowing the flowing air to be contained within the first air supply module 210.

[0131] Therefore, the movement of air from the first air supply module 210 to the second air supply module 220 is blocked, and the movement of air from the second air supply module 220 to the first air supply module 210 is blocked, so that the air supply actions of the first air supply module 210 and the second air supply module 220 can be completed independently.

[0132] The second partition wall 214b can be formed between the second air supply module 220 and the third air supply module 230 to separate the second air supply module 220 and the third air supply module 230. The second partition wall 214b can be arranged horizontally between the second air supply module 220 and the third air supply module 230.

[0133] The second partition wall 214b can contact the second corresponding partition wall 215b of the corresponding protective housing 2300, thereby allowing the flowing air to be contained within the second air supply module 220.

[0134] Therefore, the movement of air from the second air supply module 220 to the third air supply module 230 is blocked, and the movement of air from the third air supply module 230 to the second air supply module 220 is also blocked, so that the air supply actions of the second air supply module 220 and the third air supply module 230 can be completed independently.

[0135] The third partition wall 214c can be formed on the lower side of the third air supply module 230. The third partition wall 214c can be arranged in a horizontal direction.

[0136] The third partition wall 214c can contact the third corresponding partition wall 215c of the corresponding protective housing 2300, thereby confining the flowing air within the third air supply module 230.

[0137] Therefore, by blocking the movement of air expelled from the third air supply module 230 to the lower side of the third air supply module 230, the air supply action of the third air supply module 230 can be completed independently.

[0138] The number of such partition wall sections 214 and corresponding partition wall sections 215 can be determined according to the number of air supply module sections 2100.

[0139] At least one of the partition wall portion 214 and the corresponding partition wall portion 215 may be provided with concave and convex portions 216, 217, 219 that can improve airflow performance.

[0140] The protrusions and depressions may include a first protrusion and depression 216 disposed on the partition wall portion 214. The first protrusion and depression 216 can reduce frictional resistance when the rotational flow generated during the rotation of the air supply fans 212, 222, and 232 collides with the partition wall portion 214.

[0141] The partition wall 214 may include a mounting surface that extends obliquely or with an arc along the rotation path of the air supply fans 212, 222, 232, and the first protrusion 216 may be provided on the mounting surface.

[0142] The mounting surface can be formed to face the edge 212c of the air supply fan 212, 222, 232.

[0143] The first uneven portion 216 can be configured with alternating protrusions and recesses. From a different viewpoint, the first uneven portion 216 can be configured to include a plurality of grooves formed in the recess of the mounting surface.

[0144] If the air supply fans 212, 222, and 232 are driven, airflow is generated along the setting surface. The frictional resistance between the airflow and the setting surface can be reduced when passing through the first concave-convex portion 216, and the flow performance can be improved.

[0145] The first protrusion 216 can be provided in each of the first to third partition walls 214a, 214b, 214c in correspondence with the first to third air supply modules 210, 220, 230.

[0146] The protrusions and depressions may include a second protrusion and depression 217 disposed on the corresponding partition wall portion 215. The second protrusion and depression 217 can reduce frictional resistance when the rotational flow generated during the rotation of the air supply fans 212, 222, and 232 collides with the corresponding partition wall portion 215.

[0147] The corresponding partition wall 215 may include a mounting surface that extends obliquely or with an arc along the rotation path of the air supply fans 212, 222, 232, and the second protrusion 217 may be provided on the mounting surface.

[0148] The mounting surface can be formed to face the edge 212c of the air supply fan 212, 222, 232.

[0149] The second uneven portion 217 can be configured with alternating protrusions and recesses. From different viewpoints, the second uneven portion 217 may include a plurality of grooves formed in the recess of the mounting surface.

[0150] If the air supply fans 212, 222, and 232 are driven, airflow is generated along the setting surface. The frictional resistance between the airflow and the setting surface can be reduced when passing through the second concave-convex portion 217, and the flow performance can be improved.

[0151] The second concave-convex portion 217 can be disposed in each of the first corresponding partition wall 215a, 215b, 215c in correspondence with the first air supply module to the third air supply module 210, 220, 230.

[0152] If the air supply module 2100 is rotated to cover the protective housing 2300 and joined together, the partition wall 214 and the corresponding partition wall 215 come into contact with each other, and the first protrusion 216 and the second protrusion 217 can be configured to be connected to each other or very close to each other.

[0153] Therefore, the first uneven portion 216 and the second uneven portion 217 can have a shape that is continuously arranged in the front-back direction. According to the configuration described above, the area of ​​the uneven portions on the outer periphery of the air blowers 212, 222, and 232 is increased, thereby further reducing frictional resistance.

[0154] The protrusions and depressions may include third protrusions and depressions 219 provided on the air supply housings 213, 223, and 233. The third protrusions and depressions 219 provided on the first to third air supply housings 213, 223, and 233 have the same configuration, and are therefore collectively referred to as air supply housings and described herein.

[0155] The air supply housing 213, 223, 233 may include: a first part forming the back side and having a flat surface; and a second part protruding rearward from the first part and having a motor support 213a.

[0156] The first part can be set as the perimeter surrounding the second part.

[0157] The third concave-convex portion 219 can be provided in the first portion.

[0158] The third concave-convex portion 219 can be formed with an arc shape, corresponding to the rotation direction of the air supply fans 212, 222, and 232.

[0159] The third concave-convex portion 219 can be formed with an arc shape, corresponding to the curvature of the airflow generated by the blower fans 212, 222, 232.

[0160] The third protrusion 219 may include ribs protruding from the flat surface of the first portion. A plurality of ribs may be provided, and the plurality of ribs may be spaced apart from each other.

[0161] The extension angles of the plurality of ribs can be different from each other. As an example, the angles formed by the plurality of ribs relative to the extension lines passing through the centers of the air supply fans 212, 222, and 232 in the vertical direction can be different from each other.

[0162] Based on the configuration described above, when generating airflow based on the rotation of the blower fans 212, 222, and 232, the airflow is easily guided towards the exhaust side of the blower fans 212, 222, and 232. Here, the exhaust side refers to the direction on both sides of the blower fans 212, 222, and 232, which can be understood as the direction in which the side exhaust port 2111 is formed.

[0163] A protective housing 2300 may be included in front of the heat exchanger 3100 of the heat exchange assembly 3000 to guide air through the heat exchanger 3100 to the air supply module 2100.

[0164] The protective housing 2300 is disposed between the outlet side of the heat exchanger 3100 and the inlet side of the air supply module 2100.

[0165] The protective housing 2300 of this utility model embodiment can function to draw in air that has passed through the heat exchanger 3100 along the axial direction of the fan.

[0166] Since the outlet side of the heat exchanger 3100 and the inlet side of the air supply module 2100 are connected by the protective housing 2300, the air passing through the heat exchanger 3100 can move stably toward the air supply module 2100.

[0167] At this time, the air passing through the heat exchanger 3100 moves along the curved protective housing 2300, thus reducing the flow separation of the air moving from the heat exchanger 3100 to the inlet side of the air supply module 2100.

[0168] Furthermore, since a protective housing 2300 is provided between the outlet side of the heat exchanger 3100 and the inlet side of the air supply module 2100, pressure loss of the air supply airflow can be prevented. In addition, flow noise can be reduced by reducing the generation of eddies caused by flow separation of the air supply airflow inside the upper housings 1100 and 1200.

[0169] Therefore, the protective housing 2300 may have a housing body 2310 and a suction guide 2320, wherein the suction guide 2320 is disposed on the housing body 2310 and forms a suction opening 2321. As an example, the housing body 2310 may be in the shape of a quadrilateral plate, and the suction opening 2321 may be in the shape of a circle.

[0170] From the perspective of providing the intake side passages for the air supply fans 212, 222, and 232, the intake guide 2320 can also be referred to as an "orifice".

[0171] The width of the housing body 2310 can be made slightly larger than the width of the heat exchanger 3100 so as to cover the heat exchanger 3100 as a whole, thereby allowing the air passing through the heat exchanger 3100 to flow smoothly into the air supply module 2100.

[0172] The protective housing 2300 is disposed between the heat exchanger 3100 and the air supply module 2100, and forms a guide flow path for guiding the air that passes through the heat exchanger 3100 to the inlet side of the air supply module 2100.

[0173] The housing body 2310 may include a plate portion 2330 forming the periphery of the suction guide portion 2320. The plate portion 2330 may have a flat plate shape connecting the corners of the suction guide portion 2320 and the housing body 2310.

[0174] The plate portion 2330 is configured to connect to the intake guide portion 2320 and face the air supply module portion 2100.

[0175] The intake guide 2320 can be configured to guide air that has passed through the heat exchanger 3100 to the air supply module 2100.

[0176] Multiple intake guides 2320 can be formed to correspond to the air supply module 2100. For example, they can be arranged in a vertical direction. Each intake guide 2320 can contact the rear side of the first air supply housing 213, the second air supply housing 223, and the third air supply housing 233 so that the air passing through the intake guide 2320 can be transmitted to the inside of the air supply fan assembly 2000 without air leakage.

[0177] The inhalation guide 2320 may include a first inhalation guide 2321, a second inhalation guide 2322, and a third inhalation guide 2323. The first inhalation guide 2321 may be connected to the first air supply module 210 in a fluid-flowable manner, the second inhalation guide 2322 may be connected to the second air supply module 220 in a fluid-flowable manner, and the third inhalation guide 2323 may be connected to the third air supply module 230 in a fluid-flowable manner.

[0178] The first to the third inhalation guides 2321, 2322, and 2323 can form a circular outlet, but they can also be implemented in various other ways.

[0179] The first inhalation guide 2321, the second inhalation guide 2322, and the third inhalation guide 2323 may each include an edge portion 2325 forming an inner peripheral surface.

[0180] The edge portion 2325 can be provided in a plurality of numbers corresponding to the number of fans, and the plurality of edge portions 2325 can be provided corresponding to each of the first to third air supply modules 210, 220, 230.

[0181] The edge portion 2325 may be formed into a bell-shaped opening, which defines the periphery of the first to third intake guide portions 2321, 2322, and 2323 and guides the air drawn in to the first to third air supply modules 210, 220, and 230. The bell-shaped opening may include the inflow-side end of the edge portion 2325 closest to the heat exchanger 3100.

[0182] The edge portion 2325 may include a curved surface portion in the shape of a recessed groove. The curved surface portion may be configured adjacent to the first air supply module 210 having a rearwardly projecting front end, thereby preventing air leakage to the outside of the housing 2300.

[0183] The plate portion 2330 includes a corresponding partition wall portion 215, which faces and contacts the partition wall portion 214 of the air supply module portion 2100. The corresponding partition wall portion 215 includes a first corresponding partition wall 215a, a second corresponding partition wall 215b, and a third corresponding partition wall 215c.

[0184] The first corresponding partition wall 215a can be formed to separate the first suction guide portion and the second suction guide portion. The first corresponding partition wall 215a is arranged horizontally in relation to the first partition wall 214a, and protrudes forward from the boundary between the first suction guide portion and the second suction guide portion to contact the first partition wall 214a.

[0185] Therefore, the movement of air expelled through the first intake guide to the second intake guide is blocked, and the movement of air expelled through the second intake guide to the first intake guide is blocked, so the air supply action of the first intake guide and the second intake guide can be completed independently.

[0186] The second corresponding partition wall 215b can be formed to separate the second suction guide and the third suction guide. The second corresponding partition wall 215b is arranged horizontally in relation to the second partition wall 214b, and protrudes forward from the boundary between the second suction guide and the third suction guide to contact the second partition wall 214b.

[0187] Therefore, the movement of air expelled through the second intake guide to the third intake guide is blocked, and the movement of air expelled through the third intake guide to the third intake guide is also blocked, so that the air supply actions of the second intake guide and the third intake guide can be completed independently.

[0188] Furthermore, the third corresponding partition wall 215c may be formed on the lower side of the third suction guide portion. The third corresponding partition wall 215c is arranged horizontally in correspondence with the third partition wall 214c, and protrudes forward from the lower side of the third suction guide portion to contact the third partition wall 214c.

[0189] Therefore, by blocking the movement of air expelled from the third intake guide section to the lower side of the third intake guide section, the air supply action of the third intake guide section can be completed independently.

[0190] The air supply module 2100 and the protective housing 2300 can constitute a "fan housing" that houses the air supply fans 212, 222, and 232. The fan housing can form an internal space that accommodates the air supply fans 212, 222, and 232.

[0191] The fan housing can be configured such that the internal space is open, allowing the user easy access to the air supply fan 212, 222, 232.

[0192] From different perspectives, it is possible to configure at least one part of the fan housing to be separable from another part in order to open up the internal space of the fan housing.

[0193] As an example, the air supply module 2100 can be rotated relative to the protective housing 2300 by means of the hinge 2430, thereby opening and closing in the front-to-back direction.

[0194] When the air supply module 2100 is opened from the protective housing 2300 at a predetermined angle, the air supply housings 213, 223, and 233 of the air supply module 2100 and the air supply fans 212, 222, and 232 can be opened to the outside, while the front of the protective housing 2300 facing the air supply module 2100 can also be opened to the outside. Therefore, the user can clean the dust and other foreign objects collected in the separated air supply module 2100 and protective housing 2300.

[0195] When the air supply module 2100 is closed in the protective housing 2300, that is, when it forms the fan housing, it is necessary to seal the internal space of the fan housing to prevent air leakage.

[0196] In detail, the partition wall portion 214 of the air supply module portion 2100 may include a contact surface 283, which contacts the corresponding partition wall 215 of the protective housing 2300 when the air supply module portion 2100 is closed in the protective housing 2300.

[0197] The contact surface 283 may be formed on the back side of the partition wall portion 214.

[0198] The partition wall portion 214 may include a first protruding rib 281 and a second protruding rib 282. The first protruding rib 281 and the second protruding rib 282 may protrude rearward from both ends of the partition wall portion 214. As an example, the first protruding rib 281 may be provided at the lower end of the partition wall portion 214, and the second protruding rib 282 may be provided at the upper end of the partition wall portion 214.

[0199] The contact surface 283 may be formed between the first protruding rib 281 and the second protruding rib 282.

[0200] Each of the first to third partition walls 214a to 214c may be provided with a first protruding rib 281, a second protruding rib 282, and a contact surface 283.

[0201] The upper side of the first air supply module 210 may include a first guide wall 250. The first guide wall 250 may be configured to protrude rearward from the air supply housing 213 and contact the upper part of the protective housing 2300. The first guide wall 250 may have a groove for engaging with the upper hinge 2431.

[0202] The first guide wall 250 has a structure substantially similar to that of the first to third partition walls 214a, 214b, and 214c, and can be understood as a component of the partition wall portion 214. For ease of explanation, the first guide wall 250 can be referred to as the "fourth partition wall".

[0203] A first protruding rib 281 may be provided at the lower end of the first guide wall 250.

[0204] At least one of the first partition wall to the third partition wall 214a to 214c and the first guide wall 250 may be provided with an air handling device 260 for handling air passing through the air supply module.

[0205] As an example, an air handling device 260 may be provided on the first partition wall 214a, the second partition wall 214b and the second guide wall 250.

[0206] The air handling unit 260 may include a sterilization device for sterilizing the air. As an example, the sterilization device may include an ultraviolet lamp that emits ultraviolet light or an ion generator.

[0207] As another example, a sensor device 260 for sensing the temperature or humidity of the air can be installed on either of the first or second partition walls located on both sides of the air supply fans 212, 222, and 232.

[0208] The housing 2300 may have a mounting slot 265 for accommodating the air handling unit 260. The mounting slot 265 may be provided at a position where the air handling unit 260 can be inserted when the air supply module 2100 is closed in the housing 2300.

[0209] The housing 2300 may include a protrusion 285 configured to contact the contact surface 283 of the air supply module 2100.

[0210] The protrusion 285 is provided on the first corresponding partition wall to the third corresponding partition wall 215a to 215c and the second guide wall 255. Specifically, it can protrude forward from the front of the first corresponding partition wall to the third corresponding partition wall 215a to 215c and the second guide wall 255.

[0211] The second guide wall 255 is the upper side wall of the protective housing 2300 and can be configured to contact the first guide wall 250.

[0212] When the air supply module 2100 is closed in the protective housing 2300, the protrusion 285 can be configured to contact the contact surface 283 between the first protruding rib 281 and the second protruding rib 282. This combination structure (contact structure) can improve the sealing effect of the air supply module 2100 and the protective housing 2300 that constitute the fan cover.

[0213] On the other hand, discharge portions 2110 are provided on both sides of the air supply module 2100, and side discharge ports 2111 are formed in the discharge portions 2110.

[0214] The discharge portion 2110 can be disposed on the side of the air supply fan assembly 2000. Side discharge ports 2111 can be formed on both sides of the discharge portion 2110 to discharge air flowing from the air supply module 2100 to the outside.

[0215] The air supply module 2100 may include an air supply module cover 2101 that forms the overall appearance of the air supply module 2100. The air supply module cover 2101 may be formed in the shape of a hollow frame. Components constituting the air supply module 2100 may be installed inside the air supply module cover 2101. As an example, the air supply module cover 2101 may be formed in the shape of a quadrilateral frame with a longer vertical length.

[0216] The air supply module cover 2101 may include: a pair of discharge portions 2110, each standing upright on both sides of the air supply module cover 2101; and a connecting portion 2120 connecting the pair of discharge portions 2110.

[0217] A pair of discharge portions 2110 can form the two sides of the air supply module cover 2101. Side door assemblies 2130 can be respectively attached to each pair of discharge portions 2110. The pair of discharge portions 2110 can each be formed into a quadrilateral plate shape with a longer vertical length. The pair of discharge portions 2110 can be configured to tilt forward. As an example, the pair of discharge portions 2110 can be configured to tilt towards each other in a forward direction to improve airflow performance.

[0218] The discharge portion 2110 may have a side discharge port 2111 for discharging air drawn in by the blower fans 212, 222, and 232 to the outside. The side discharge port 2111 may be formed by cutting at least a portion of the discharge portion 2110 in the vertical direction.

[0219] The discharge section 2110 may have a discharge grille 2112 for forming an airflow of the discharged air. The discharge grille 2112 may be configured with a plurality of ribs in a grid shape on the inner side of the side discharge port 2111.

[0220] The exhaust grille 2112 may include a plurality of vertical and horizontal ribs that divide the side exhaust outlets 2111. The plurality of vertical ribs may be arranged obliquely towards the front and outward. As an example, the plurality of vertical ribs may be arranged obliquely towards the side exhaust outlets 2111 to improve aerodynamic performance.

[0221] A first groove 2113 can be formed in the ejection portion 2110, which is a side door drive part that provides driving force to the side door assembly 2130. Figure 9 The side door drive unit 2122 is disposed in the first slot 2113. The side door drive unit 2122 may be disposed inside the first slot 2113. The side door drive unit 2122 can be connected to the side door assembly 2130 through the first slot 2113 and provide a driving force for moving the side door assembly 2130 in the forward and backward direction.

[0222] Multiple first grooves 2113 can be formed. Multiple first grooves 2113 can be formed at the upper and lower ends of the discharge portion 2110 respectively.

[0223] A second groove 2114 can be formed in the ejection portion 2110 to guide the door support member of the side door assembly 2130 to move in the front-back direction. Figure 9 The door support member 2123 is disposed in the second groove 2114. The door support member 2123 may be disposed inside the second groove 2114. The door support member 2123 can be connected to the side door assembly 2130 through the second groove 2114, and performs the function of guiding the side door assembly 2130 to move in the front and back direction and supporting the side door assembly 2130.

[0224] The second slot 2114 can be formed in a plurality of ways to support the load of the side door assembly 2130. The plurality of second slots 2114 can be arranged spaced apart along the length of the ejection portion 2110.

[0225] The connecting portion 2120 can be formed to connect a pair of discharge portions 2110 and form the back side of the air supply module cover 2101. The connecting portion 2120 can be formed in the shape of a quadrilateral plate with a longer vertical length. The connecting portion 2120 can be formed in a shape in which at least a portion protrudes rearward.

[0226] Based on the connecting portion 2120, a blower motor can be arranged in front of the connecting portion 2120, and blower fans 212, 222, and 232 can be arranged behind the connecting portion 2120. Therefore, in the space between the pair of discharge portions 2110 and the connecting portion 2120, an discharge flow path 2120a can be formed, which guides the air flowing in from the intake opening 2321 to the side discharge port 2111.

[0227] The connecting portion 2120 may include air supply housings 213, 223, and 233, which form a motor support portion 213a supporting the air supply motor. A plurality of air supply housings 213, 223, and 233 may be formed and spaced apart along the vertical direction.

[0228] The connecting portion 2120 may include blade support ribs 2126 supporting the side blade module 2200.

A pair of blade support ribs 2126 may be formed and respectively disposed on both sides of the air supply housings 213, 223, and 233. A portion of the blade support ribs 2126 may be inserted into the inner side of the side blade module 2220.

[0229] The air supply module cover 2101 may include a top panel 2140 disposed on the upper side of a pair of discharge portions 2110.

[0230] The top panel 2140 can form the top surface appearance of the air supply fan assembly 2000. The top panel 2140 can be detachably attached to the upper side of the air supply module 2100. The top panel 2140 can be configured to cover the open top surface of the air supply module 2100. As an example, the top panel 2140 can be formed in the shape of a quadrilateral plate.

[0231] From the perspective of forming the top surface appearance of the indoor unit, it can be understood that the top panel 2140 is a component of the housing assembly 1000.

[0232] From the perspective of forming the side appearance of the indoor unit, it can be understood that the side door assembly 2130, described later, is a component of the housing assembly 1000.

[0233] As described above, the housing assembly 1000 can be understood to include a plurality of separate components, namely, the main front housing 1100, the main rear housing 1200, the lower housing 5000, the top panel 2140, and the side door assembly 2130, to form the appearance of the indoor unit. However, any two or more of the plurality of components may be integrally formed, or any of the plurality of components may be omitted.

[0234] Side door assemblies 2130 with opening and closing side discharge ports 2111 are provided on the discharge portions 2110 located on both sides of the air supply fan assembly 2000. The side door assemblies 2130 can be formed separately from the discharge portions 2110.

[0235] The side door assembly 2130 can be configured to extend from the upper end of the upper housing 1100, 1200 of the housing assembly 1000 to the boundary of the lower housing 5000 with a specified width.

[0236] The side door assembly 2130 serves to open and close the side outlets 2111 of the discharge portion 2110 formed on both sides of the air supply fan assembly 2000.

[0237] When the indoor unit is running, the side door assembly 2130 opens the side outlet 2111; when the indoor unit is not running, the side door assembly 2130 blocks the side outlet 2111.

[0238] When the indoor unit is running, the side door assembly 2130 opens the side outlet 2111 to discharge air blown out by the air supply module 2100.

[0239] Conversely, when the indoor unit is not in operation, the side door assembly 2130 blocks the side outlet 2111, which effectively prevents dust and other particles from flowing into the interior through the side outlet 2111 and from adhering to or blocking foreign objects that may cause malfunctions from flowing in.

[0240] As another example of operation, when the indoor unit is running, either of the two side door assemblies 2130 can open one side outlet 2111 to expel air to the outside, while the other side door assembly 2130 blocks the other side outlet 2111 to prevent air from being expelled (one-sided air expulsion mode).

[0241] As an example, either the side outlet 2111 on one side or the side outlet 2111 on the other side can be the left side outlet, while the other can be the right side outlet.

[0242] The side door assembly 2130 as described above includes: left and right side doors 2121, which open and close side outlets 2111 as they move in the front-back direction; and a support frame 2124, which has guide holes 2125 to guide the front-back movement of the side doors 2121.

[0243] The side door assembly may include: a side door drive unit 2122 that applies driving force to the side door 2121; and a door support member 2123 that supports each side door 2121 on the ejection portion 2110. Here, the side door drive unit 2122 and door support member 2123, which are provided in a plurality of form on the side door 2121 and the support frame 2124, may be referred to as a side door module 2120.

[0244] The side door assembly 2130 can be supported so that it can move from the foremost position of blocking the side outlet 2111 to the rearmost position of opening the side outlet 2111.

[0245] Referring to the accompanying drawings, the side door assembly 2130 can extend from the upper end of the upper housing 1100, 1200 of the housing assembly 1000 to the boundary of the lower housing 5000 and cover the whole with a specified width. The outer surface of the side door 2121 can be configured to have a shape that can form the same texture as the main front housing 1100 and the base front 5300, so as to create an aesthetic sense for the user of the indoor unit and a sense of unity between the air supply fan assembly 2000 and the main rear housing 1200.

[0246] Figure 11 This is a sectional perspective view of the side door module according to an embodiment of the present invention.

[0247] Reference Figure 11 The side door drive unit 2122 may include: a rack 2122a disposed on the inner surface of the support frame 2124; a pinion 2122b meshing with the rack 2122a; and a drive motor 2122c providing driving force to the pinion 2122b so that the support frame 2124 can move left and right.

[0248] The rotational force of the pinion 2122b, which is connected to the output shaft of the drive motor 2122c provided in the side door drive unit 2122, can be converted into linear reciprocating motion of the support frame 2124, which has a rack 2122a.

[0249] The drive motor 2122c and pinion 2122b can be disposed in the ejection portion 2110, and the rack 2122a that can mesh with the pinion 2122b can be formed on the inner surface of the support frame 2124 of the side door assembly 2130.

[0250] Here, the discharge portion 2110, which is equipped with the drive motor 2122c and the pinion 2122b, is not the portion that forms the side discharge port 2111, but can be a portion of the panel portion 2112 that is plate-shaped and located on one side of the side discharge port 2111.

[0251] One end of the door support member 2123 can be fixed to the ejection portion 2110, while the other end can be supported in the support frame 2124 of the side door assembly 2130, so that the side door assembly 2130 is supported in the ejection portion 2110 of the air supply fan assembly 2000 and can achieve stable opening and closing action.

[0252] As previously described, the side door assembly 2130 may be configured to extend from the upper end of the upper housing 1100, 1200 of the housing assembly 1000 to the boundary of the lower housing 5000 with a specified width.

[0253] The side door 2121 and the support frame 2124 of the side door assembly 2130 are plate-shaped components that are formed long along the length direction and are in a state of being joined together.

[0254] Figure 12 This is a perspective view of the side blade module of an embodiment of the present invention.

[0255] Reference Figure 12 The side door assembly 2130 can be tilted forward and guide the air expelled from the housing assembly 1000 forward. Thus, the air discharged through the side outlet 2111 is redirected by the side blade module 2200 to form a forward-directing airflow. Here, the forward-directing airflow can be defined as an exhaust airflow with a defined exhaust angle relative to the front.

[0256] The side blade module 2200 is a blade that converts the direction of the forward-facing airflow exiting through the side outlet 2111, and is disposed in front of the air supply fan assembly 2000. Furthermore, the side blade module 2200 may include a side blade housing 2210 and side blades 2220. The conversion of the forward-facing airflow direction by the side blade module 2200 is achieved by a plate-shaped side blade 2220 disposed adjacent to the front side of the side outlet 2111.

[0257] The side blades 2220 of the side blade module 2200 are kept hidden between the main front housing 1100 and the air supply fan assembly 2000, and can thus be referred to as hidden blades.

[0258] Therefore, the side blades 2220 do not affect the airflow through the side outlet 2111, and the discharged air can maintain a forward-facing airflow.

[0259] However, when the blade drive unit 2215 is operated to switch from direct wind mode to indirect wind mode, the side blades 2220 can move horizontally from the hidden state to the direction of being exposed to the outside.

[0260] When the horizontal movement of the side blade 2220 begins, the side blade 2220 stops after completing its movement to the final fully open position.

[0261] If the side blades 2220 complete their movement to the fully open position, the air expelled through the side outlet 2111 is resisted by the side blades 2220. In particular, the air at the front end of the side outlet 2111 collides directly with the side blades 2220, and its direction of movement is reversed. At this time, since the air at the front end of the air expelled through the side outlet 2111 has the fastest flow velocity, the air whose direction of movement is reversed due to the collision with the side blades 2220 affects the direction of movement of the air expelled from the rear side. Due to this effect, the overall direction of movement of the air through the side outlet 2111 is reversed, thereby forming a lateral airflow.

[0262] The side blades 2220 of the side blade module 2200 move in the left-right direction relative to the side blade housing 2210 via the blade drive unit 2215. The side blade 2220 may have a left side blade 2220 and a right side blade 2220.

[0263] The blade drive unit 2215 includes: a drive motor 2211 that drives the side blades 2220 electrically; a pinion 2212 connected to the output shaft of the drive motor 2211; and a rack 2214 that converts the rotational force of the pinion 2212 into linear reciprocating motion.

[0264] Here, the drive motor 2211 and the pinion 2212 can be disposed on the side blade housing 2210, and the rack 2214 that can mesh with the pinion 2212 can be disposed on the inner surface of the side blade 2220.

[0265] The drive motor 2211 can be configured to be firmly supported at any position on the side blade housing 2210 by an additional bracket 2213, and the rack 2214 that meshes with the pinion 2212 can be integrally formed with the side blade 2220 or separately formed and combined with the side blade 2220.

[0266] According to an embodiment of the present invention, in order to clean the air supply fans 212, 222, and 232, the air supply module 2100 is configured to be able to open and close the main body front housing 1100 and the air supply fan assembly 2000 from the housing assembly 1000.

[0267] Figure 13 and Figure 14 This is a perspective view showing the hinge portion of an embodiment of the present utility model.

[0268] Reference Figure 13 and Figure 14 The air supply module 2100 can be rotated relative to the protective housing 2300 by means of the hinge 2430, thereby opening and closing in the front and back direction.

[0269] The hinge portion 2430 includes an upper hinge 2431 and a lower hinge 2432. Here, the upper hinge 2431 is located on the upper side of the air supply fan assembly 2000 and the protective housing 2300, and the lower hinge 2432 is located on the lower side of the air supply fan assembly 2000 and the protective housing 2300.

[0270] The main body front shell 1100 and the air supply module 2100 are rotatably connected to the protective shell 2300 by the upper hinge 2431 and the lower hinge 2432.

[0271] An upper hinge bracket and a lower hinge bracket 2440 are provided on one side of the protective housing 2300, with the upper hinge 2431 and lower hinge 2432 fixed on one side by a hinge shaft 2433. At this time, bracket mounting grooves 2350 can be formed on the upper and lower sides to prevent the upper hinge bracket and the lower hinge bracket 2440 from protruding outward from the protective housing 2300.

[0272] The upper hinge bracket and the lower hinge bracket 2340 form a rotation space, so that the upper hinge 2431 and the lower hinge 2432 can rotate by means of the hinge axis 2433.

[0273] In the upper hinge bracket and the lower hinge bracket 2440, the front of the rotation space and the hinge insertion surface are open, and the bracket mounting slot 2350 of the protective housing 2300 is set at the same height, so that the upper hinge 2431 and the lower hinge 2432 can rotate in the rotation space.

[0274] Each of the upper hinges 2431 and the lower hinge 2432 is bent so that each end extends in a direction of approximately 90°.

[0275] A shaft insertion hole 2434 is formed on one side of the upper hinge 2431 and the lower hinge 2432, into which the hinge shaft 2433 is rotatably inserted. A connecting member 2435 is formed on the other side of the upper hinge 2431 and the lower hinge 2432, and the connecting member 2435 is fixedly connected to the first air supply housing 213 and the third air supply housing 233 of the air supply fan assembly 2000.

[0276] The upper hinge 2431 and the lower hinge 2432 can be configured such that, when rotating about the hinge axis 2433, a portion of the upper hinge 2431 and the lower hinge 2432 are drawn out from the rotation space of the upper hinge support and the lower hinge support 2340, thus being exposed or contained in the rotation space.

[0277] The air supply module 2100 of the main body front shell 1100 and the air supply fan assembly 2000 can rotate from the protective shell 2300 via the hinge 2430.

[0278] As shown in the figure, the air supply module 2100 can be opened and closed with the hinge 2430 connecting the air supply fan assembly 2000 and the protective housing 2300 as the center.

[0279] When the air supply module 2100 is opened from the protective housing 2300 at a predetermined angle, the air supply housings 213, 223, 233 and the air supply fans 212, 222, 232 of the air supply module 2100 can be opened to the outside, and the front of the protective housing 2300 facing the air supply module 2100 can be opened to the outside.

[0280] Therefore, users can clean the dust and other foreign objects collected in the separated air supply module 2100 and the protective housing 2300.

[0281] Figure 15 and Figure 16 This is a perspective view showing the hinge portion and roller bracket of an embodiment of the present invention. Figure 17 This is a perspective view of the bottom surface of the roller bracket according to an embodiment of the present utility model.

[0282] Reference Figures 15 to 17 On the side of the air supply fan assembly 2000 where the lower hinge 2432 is located, a roller bracket 3120 is provided. The roller bracket 3120 is integrated with the air supply fan assembly 2000 and rolls along the top surface of the horizontal base 3110 between the upper housing 100 and the lower housing 110 when rotating towards the protective housing 2300 or away from the protective housing 2300.

[0283] The roller bracket 3120 is configured to prevent the hinge part 2430 from sagging due to the load of the air supply fan assembly 2000 when the air supply fan assembly 2000 is opened forward. It is configured to clean dust and other foreign objects collected on the air supply fan assembly 2000 and the protective housing 2300 while the air supply fan assembly 2000 is opened stably.

[0284] The roller bracket 3120 includes a bracket body 3121, which is located directly below the lower hinge 2432, that is, the lower end of the lower hinge 2432 side of the third air supply housing 233 protrudes towards the protective housing 2300.

[0285] The support body 3121 of this utility model embodiment is a hollow cover shape and is vertically arranged so as to be installed on the inlet side of the third air supply housing 233. The support body 3121 includes: a first vertical plate 3121a, which contacts the third air supply housing 233; a horizontal plate 3121b, which is bent at a right angle from the upper end of the first vertical plate 3121a and extends in the horizontal direction; and a second vertical plate 3121c, which is formed at a predetermined interval from the inlet side of the third air supply housing 233 and connected between the first vertical plates 3121a.

[0286] In addition, the bottom part of the bracket body 3121 and the lower end of the third air supply housing 233 of the air supply fan assembly 2000 are on the same line.

[0287] On the other hand, a cutout 2301 is formed in the portion of the protective housing 2300 corresponding to the rotation trajectory of the roller bracket 3120, so that the roller bracket 3120 will not interfere with the protective housing 2300 when the air supply fan assembly 2000 rotates using the hinge portion 2430.

[0288] At this time, it is necessary to prevent the side portion of the support body 3121 from interfering with the side portion of the cut portion 2301 located on the rotation trajectory of the roller support 3120, so that the roller support 3120 can roll smoothly along the rotation trajectory. For this purpose, the corner where the first vertical plate 3121a and the second vertical plate 3121c of the support body 3121 intersect can be bent into an arc shape.

[0289] At least one roller 3122 is provided on the support body 3121 to contact and rotate with the bottom surface.

[0290] like Figure 17 As shown, the rotating roller 3122 is rotatably located in the empty space on the bottom surface of the support body 3121. The rotating roller 3122 is positioned to roll in a direction corresponding to the rotational trajectory of the support body 3121 based on the hinge portion 2430. Here, the support body 3121 travels from the air supply fan assembly 2000 toward the protective housing 2300 in an arc-shaped rotational trajectory. Here, the rotational trajectory of the support body 3121 is the same as the rotational trajectory of the hinge portion 2430.

[0291] The support body 3121 includes roller support portions 3123 for supporting rotating rollers 3122. Roller support portions 3123 are provided on both sides perpendicular to the direction of travel of the rotating rollers 3122, supporting the two ends of the rotating rollers 3122. The rotating rollers 3122 can be supported by the two roller support portions 3123.

[0292] The roller support portion 3123 has a roller insertion groove 3123a for inserting the rotating roller 3122 and a shaft support groove 3123b for inserting and supporting the rotating shaft 3122a of the rotating roller 3122.

[0293] Preferably, the shaft support groove 3123b is formed such that the width of the inlet side into which the rotating shaft 3122a is inserted is smaller than the diameter of the rotating shaft 3122a. That is, the rotating shaft 3122a needs to be inserted into the shaft support groove 3123b and rotate smoothly without disengaging. However, if the width of the inlet side of the shaft support groove 3123b is greater than the diameter of the rotating shaft 3122a, the rotating shaft 3122a is prone to disengaging from the shaft support groove 3123b. Therefore, to prevent this problem, the width of the inlet side of the shaft support groove 3123b must be smaller than the diameter of the rotating shaft 3122a.

[0294] Preferably, the rolling surface of the rotating roller 3122 is lower than the bottom surface of the support body 3121, so that the rotating roller 3122 can roll along the top surface of the horizontal base 3110 at the lower end of the protective housing 2300.

[0295] The rotating roller 3122, thus mounted on the roller bracket 3120, can distribute the load of the air supply fan assembly 2000 to the horizontal base 3110 as it rolls along the horizontal base 3110, thereby enabling the horizontal base 3110 to stably support the air supply fan assembly 2000.

[0296] Therefore, it can reduce the load on the air supply fan assembly 2000 transmitted to the hinge section 2430 when the air supply fan assembly 2000 is opened forward, while preventing the indoor unit from easily tipping over due to the load of the air supply fan assembly 2000.

[0297] Figure 18 This diagram illustrates the positional relationship of the connecting wires between the air blower assembly and the upper housing body in an embodiment of the present invention. Figure 19 This is a front view showing the air supply fan assembly according to an embodiment of the present utility model. Figure 20 This is a bottom view showing the air supply fan assembly according to an embodiment of the present utility model.

[0298] Reference Figures 18 to 20The indoor unit of this utility model embodiment may include a lower housing body 5100 forming a mechanical chamber 5102 in the lower housing 5000. The lower housing body 5100 may be disposed at the lower part of the main body rear housing 1200.

[0299] The lower housing body 5100 may include a base 5110 placed on the ground and two side portions 5120 protruding upward on both sides of the base 5110.

[0300] The machine room 5102, located in the lower housing body 5100, is an internal space defined by the base 5110 and two side sections 5120. A refrigerant pipe 3200 and a drain pipe 3300 can be installed in the machine room 5102. A main control box 5170 and the like can be installed in the center of the inner side of the machine room 5102.

[0301] The main control box 5170 can receive external power and supply power to the electrical components of the indoor unit.

[0302] The main control box 5170 can be connected to a display connection cable D that connects to the display unit 1110 of the main front housing 1100, can be connected to a communication cable C for communicating with the secondary control box 5180 of the fan assembly 2000 installed in the upper housing 1100 and 1200, and can be connected to a high voltage connection cable V.

[0303] The monitor connection cable D, communication cable C, and high-voltage connection cable V can be referred to as connecting wires.

[0304] The secondary control box 5180 can receive power from the main control box 5170 and supply it to the drive units of the air blower assembly 2000, the side door assembly 2130, and the side blade module 2200. That is, the secondary control box 5180 can be connected to a communication line C and a high-voltage connection line V.

[0305] Furthermore, the display connection cable D can be connected to the display unit 1110.

[0306] The external power supplied to the main control box 5170 can be received from the power supply source through the power socket of the indoor unit (not shown).

[0307] like Figure 19 As shown, the secondary control box 5180 of this utility model embodiment can be disposed on the front side between the second air supply module 220 and the third air supply module 230 of the air supply fan assembly 2000. That is, the secondary control box 5180 is disposed on the front side of the air supply fan assembly 2000 of the upper housing 1100, 1200.

[0308] However, the location of the secondary control box 5180 is not necessarily limited to this; it can be configured in various positions of the air supply fan assembly 2000.

[0309] The main control box 5170 can be disposed in the center of the inner side of the lower housing body 5100, which is located in the lower housing 5000.

[0310] The secondary control box 5180 can be configured to be positioned further in front of the indoor unit than the main control box 5170 when viewed from the side.

[0311] Therefore, the display connection cable D, communication cable C, and high voltage connection cable V, etc., connecting between the main control box 5170 and the secondary control box 5180 can be extended diagonally or in a stepped manner and connected.

[0312] According to an embodiment of the present invention, the indoor unit of the air conditioner can be opened and closed together with the main body front housing 1100 for cleaning the air supply fans 212, 222, and 232 installed in the air supply fan assembly 2000. That is, the air supply fan assembly 2000 can be opened from the front side of the protective housing 2300 or closed from the front side of the protective housing 2300.

[0313] At this time, the connecting wire L connecting the main control box 5170 and the auxiliary control box 5180 passes through the base portion 2001 of the third air supply housing 233, which divides the upper housing 1100, 1200 and the lower housing 5000 and is located on the lower side of the air supply fan assembly 2000.

[0314] The base portion 2001 includes a flat plate 2002 located below the third air supply module 230 of the air supply fan assembly 2000. The flat plate 2002 may be part of the third air supply housing 233.

[0315] The connecting wire L extending from the main control box 5170 of the lower housing 5000 can pass through the flat plate 2002 of the base portion 2001 of the third air supply housing 233 and extend toward the sub-control box 5180, and connect to the sub-control box 5180.

[0316] That is, the base portion 2001 may include an electrical connection passage 2003 that penetrates the flat plate 2002.

[0317] The wire connection passage 2003 is a quadrilateral-shaped through hole, through which the connecting wire L between the main control box 5170 and the auxiliary control box 5180 passes.

[0318] In the embodiments of this utility model, the through hole of the wire connection passage 2003 is formed in the shape of a quadrilateral hole, but it is not necessarily limited to this, and various shapes such as circles and ellipses can be used.

[0319] The secondary control box 5180 and the wire connection path 2003 are located in a straight line, so that the connecting wire L connected to the secondary control box 5180 can pass vertically through the wire connection path 2003.

[0320] Furthermore, the connecting wires that pass vertically through the wire connection passage 2003 can extend toward and connect to the main control box 5170, which is located at an angle relative to the wire connection passage 2003.

[0321] When the air supply fan assembly 2000, which has a secondary control box 5180, rotates using the hinge portion 2430 to open, the connecting wire L extending between the main control box 5170 and the secondary control box 5180 may interfere with the air supply fan assembly 2000 and break due to the pulling force.

[0322] Therefore, this utility model proposes an indoor unit of an air conditioner that improves the reliability of the configuration structure of the connecting wire L by changing the path of the connecting wire L that can prevent the connection between the main control box 5170 and the auxiliary control box 5180 from being disconnected.

[0323] Importantly, the connecting wire L between the main control box 5170 and the secondary control box 5180 extends through a space independent of the rotational movement of the air supply fan assembly 2000.

[0324] For this purpose, a connecting wire L extending from the secondary control box 5180 and passing through the wire connection passage 2003 passes through the roller bracket 3120 located directly below the lower hinge 2432 of the air supply fan assembly 2000.

[0325] Here, the roller support 3120 is in the shape of a hollow cover, and the lower end of the roller support 3120 is on the same line as the lower end of the base portion 2001. In addition, the base portion 2001 has an internal space that is empty below the flat plate 2002.

[0326] The internal space of the roller bracket 3120 and the internal space of the base portion 2001 are formed so that the connecting wire L passes through and is connected.

[0327] The connecting wire L, which extends from the secondary control box 5180 through the wire connection passage 2003 through the base portion 2001 and into the internal space of the roller bracket 3120, can extend below the horizontal base 3110 located between the heat exchanger 3100 and the lower housing body 5100 and connect to the main control box 5170.

[0328] The extension path of the connecting wire L between the main control box 5170 and the auxiliary control box 5180 can be a path through the wire connection passage 2003 and the inner space of the roller bracket 3120 within the inner space of the base portion 2001 formed in the air supply assembly 2000. Based on the inner space of the base portion 2001, the connecting wire L passing through the wire connection passage 2003 can be connected to the auxiliary control box 5180, and the connecting wire L passing through the roller bracket 3120 can be connected to the main control box 5170.

[0329] As mentioned above, the roller support 3120 is located at the hinge portion 2430, that is, directly below the lower hinge 2432.

[0330] When the air supply fan assembly 2000 rotates using the hinge portion 2430, the roller bracket 3120, which is located on the same vertical line as the lower hinge 2432, also has the same virtual axis center as the lower hinge 2432.

[0331] Therefore, even if the fan assembly 2000 rotates using the hinge portion 2430, the roller bracket 3120 has the same axis center as the lower hinge 2432. Thus, as long as the axis center of the hinge portion 2430 does not change, the path of the connecting wire L through the roller bracket 3120 will not change.

[0332] When the air supply fan assembly 2000 rotates using the hinge portion 2430, the roller support 3120 rolls along the top surface of the horizontal base 3110. However, since the roller support 3120 has the same axis center as the hinge portion 2430, the rotational trajectory of the roller support 3120 is not large.

[0333] The roller bracket 3120 not only prevents the hinge portion 2430 from sagging due to the load of the air supply fan assembly 2000 when the air supply fan assembly 2000 is opened forward, but also reduces the load burden applied to the hinge portion 2430.

[0334] When the air supply fan assembly 2000 is in the open state due to the stable rotation of the hinge part 2430, dust and other foreign objects that have been collected in the air supply fan assembly 2000 and the protective housing 2300 can be cleaned.

[0335] Since the roller bracket 3120 has the same axis center as the lower hinge 2432 when the air supply fan assembly 2000 rotates using the hinge part 2430, the connecting wire L that passes through the wire connection passage 2003 and through the internal space of the roller bracket 3120 can extend directly to the main control box 5170 without interfering with the air supply fan assembly 2000 and without any change in position.

[0336] The connecting wire L extending from the wire connection passage 2003 to the roller bracket 3120 can ensure that the slack length is extended without remaining taut.

[0337] This is to prevent the connecting wire L from breaking when it is in a taut state due to interference with the internal structures located in the internal space of the base 2001 and the roller bracket 3120, when the air supply fan assembly 2000 rotates using the hinge part 2430. That is, since the connecting wire L is prone to breaking when it is in a taut state, it is necessary to prevent wire breakage by ensuring sufficient slack length of the connecting wire L.

[0338] To prevent the loss of tension in the connecting wire L from causing it to sag downwards due to its inability to bear its own weight, a sag prevention part (not shown) may be included.

[0339] The anti-sagging part can be a hook for suspending and fixing the connecting wire L, or a wire drum for forcibly winding or unwinding the connecting wire L.

[0340] On the other hand, the connecting wire L, which consists of a display connection cable, a communication cable, and a high-voltage connection cable, can also be connected between the main control box 5170 and the secondary control box 5180 as a single wire through a wire guide.

[0341] The foregoing description has explained the connection structure of the connecting wire L extending from the secondary control box 5180 to the main control box 5170. The connection structure of the connecting wire L extending from the main control box 5170 to the secondary control box 5180 can also be implemented with the same connection structure as described above.

[0342] When viewing the indoor unit from the side, with the wire connection path 2003 as a reference, the connecting wire L between the secondary control box 5180 and the main control box 5170 remains in its initial connection state when the air supply fan assembly 2000 rotates, and the length and path of the connecting wire L do not change. This allows the air supply fan assembly 2000 to be opened easily and the dust and other foreign objects collected on the air supply module section 2100 and the protective housing 2300 to be cleaned more thoroughly.
