[0043] When we say that a component is "on" another component, this includes not only cases where the component is in contact with the other component, but also cases where there is another component between the two components.

[0044] An air conditioner according to various embodiments is a device that performs functions such as air purification, ventilation, humidity control, cooling or heating in an air-conditioned space (hereinafter referred to as “indoor”), and means a device equipped with at least one of these functions.

[0045] In one embodiment, an air conditioner may include a heat pump device to perform a cooling function or a heating function. The heat pump device may include a refrigeration cycle in which a refrigerant circulates along a compressor, a first heat exchanger, an expansion device, and a second heat exchanger. All components of the heat pump device may be housed in a single housing forming the exterior of the air conditioner, such as a window air conditioner or a portable air conditioner. On the other hand, some components of the heat pump device may be housed separately in multiple housings forming a single air conditioner, such as a wall-mounted air conditioner, a stand-alone air conditioner, and a system air conditioner.

[0046] An air conditioner including a plurality of housings may include at least one outdoor unit installed outdoors and at least one indoor unit installed indoors. For example, the air conditioner may be configured such that one outdoor unit and one indoor unit are connected via a refrigerant pipe. For example, the air conditioner may be configured such that one outdoor unit is connected to two or more indoor units via refrigerant pipes. For example, the air conditioner may be configured such that two or more outdoor units and two or more indoor units are connected via a plurality of refrigerant pipes.

[0047] The outdoor unit can be electrically connected to the indoor unit. For example, information (or commands) for controlling the air conditioner can be input through an input interface provided on the outdoor or indoor unit, and the outdoor and indoor units can operate simultaneously or sequentially in response to user input.

[0048] The air conditioner may include an outdoor heat exchanger provided in the outdoor unit, an indoor heat exchanger provided in the indoor unit, and a refrigerant pipe connecting the outdoor heat exchanger and the indoor heat exchanger.

[0049] An outdoor heat exchanger can utilize a phase change (e.g., evaporation or condensation) of the refrigerant to exchange heat between the refrigerant and the outdoor air. For example, while the refrigerant condenses in the outdoor heat exchanger, it releases heat to the outdoor air, and while the refrigerant flowing in the outdoor heat exchanger evaporates, it absorbs heat from the outdoor air.

[0050] Indoor units are installed indoors. For example, indoor units can be categorized into ceiling-mounted, stand-alone, and wall-mounted types depending on their placement. For example, ceiling-mounted indoor units can be categorized into four-way, one-way, and duct-type indoor units depending on how air is discharged.

[0051] Similarly, an indoor heat exchanger can utilize the phase change of the refrigerant (e.g., evaporation or condensation) to exchange heat between the refrigerant and indoor air. For example, while the refrigerant evaporates in the indoor unit, the refrigerant can absorb heat from the indoor air. The cooled indoor air can then be blown through the cooled indoor heat exchanger, thereby cooling the room. Furthermore, while the refrigerant condenses in the indoor heat exchanger, the refrigerant can release heat to the indoor air. By blowing the heated indoor air through the high-temperature indoor heat exchanger, the room can be heated.

[0052] That is, the air conditioner performs a cooling or heating function through a phase change process of the refrigerant circulating between the outdoor heat exchanger and the indoor heat exchanger. To circulate the refrigerant, the air conditioner may include a compressor that compresses the refrigerant. The compressor can suck in refrigerant gas through the suction port and compress the refrigerant gas. The compressor can discharge the high-temperature and high-pressure refrigerant gas through the discharge port. The compressor may be placed inside the outdoor unit.

[0053] The refrigerant may circulate through the refrigerant pipes in the order of a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, or in the order of a compressor, an indoor heat exchanger, an expansion device, and an outdoor heat exchanger.

[0054] For example, if an air conditioner has one outdoor unit and one indoor unit directly connected through a refrigerant pipe, the refrigerant may be arranged to circulate between one outdoor unit and one indoor unit through the refrigerant pipe.

[0055] For example, in an air conditioner, if one outdoor unit is connected to two or more indoor units via refrigerant pipes, the refrigerant can flow to multiple indoor units via refrigerant pipes branching from the outdoor unit. The refrigerant discharged from the multiple indoor units can be combined and circulated to the outdoor unit. For example, multiple indoor units can be directly connected in parallel to a single outdoor unit via separate refrigerant pipes.

[0056] Multiple indoor units can operate independently, each according to a user-defined operating mode. That is, some indoor units can operate in cooling mode, while others operate in heating mode. In this case, the refrigerant can be selectively introduced into each indoor unit at either high or low pressure along a designated circulation path via a flow-through valve, described later, and then discharged to the outdoor unit for circulation.

[0057] For example, when an air conditioner has two or more outdoor units and two or more indoor units connected through multiple refrigerant pipes, the refrigerant discharged from the multiple outdoor units may merge and flow through a single refrigerant pipe, then branch off again at some point and flow into multiple indoor units.

[0058] Multiple outdoor units may all be operated, or at least some may not be operated, depending on the operating load of the multiple indoor units. In this case, the refrigerant may be introduced into the outdoor unit, which is selectively operated, through a flow switching valve and circulated there. The air conditioner may include an expansion device to reduce the pressure of the refrigerant flowing into the heat exchanger. For example, the expansion device may be located within the indoor unit, the outdoor unit, or both.

[0059] An expansion device can, for example, utilize a throttling effect to lower the temperature and pressure of the refrigerant. The expansion device may include an orifice capable of reducing the cross-sectional area of ​​the flow path. Refrigerant passing through the orifice may experience a decrease in temperature and pressure.

[0060] The expansion device may be implemented as, for example, an electronic expansion valve capable of controlling the opening ratio (the ratio of the cross-sectional area of ​​the valve's flow path when partially open to the cross-sectional area of ​​the valve's flow path when fully open). Depending on the opening ratio of the electronic expansion valve, the amount of refrigerant passing through the expansion device can be controlled.

[0061] The air conditioner may further include a flow diverter valve positioned along the refrigerant circulation path. The flow diverter valve may include, for example, a four-way valve. The flow diverter valve may determine the refrigerant circulation path depending on the indoor unit's operating mode (e.g., cooling operation or heating operation). The flow diverter valve may be connected to the discharge port of the compressor.

[0062] The air conditioner may include an accumulator. The accumulator may be connected to the suction port of the compressor. The accumulator may receive low-temperature, low-pressure refrigerant vaporized in an indoor heat exchanger or an outdoor heat exchanger.

[0063] The accumulator can separate the refrigerant liquid from the refrigerant gas when a refrigerant mixture of refrigerant liquid and refrigerant gas is introduced, and provide the refrigerant gas from which the refrigerant liquid has been separated to the compressor.

[0064] An outdoor fan may be installed near the outdoor heat exchanger. The outdoor fan may blow outdoor air to the outdoor heat exchanger to promote heat exchange between the refrigerant and the outdoor air.

[0065] The outdoor unit of the air conditioner may include at least one sensor. For example, the sensor of the outdoor unit may be provided as an environmental sensor. The outdoor unit sensor may be positioned at any location inside or outside the outdoor unit. For example, the outdoor unit sensor may include a temperature sensor for detecting the air temperature around the outdoor unit, a humidity sensor for detecting the air humidity around the outdoor unit, a refrigerant temperature sensor for detecting the refrigerant temperature of a refrigerant pipe passing through the outdoor unit, or a refrigerant pressure sensor for detecting the refrigerant pressure of a refrigerant pipe passing through the outdoor unit.

[0066] An outdoor unit of an air conditioner may include an outdoor unit communication unit. The outdoor unit communication unit may be configured to receive a control signal from a control unit of an indoor unit of the air conditioner, which will be described later. The outdoor unit may control the operation of a compressor, an outdoor heat exchanger, an expansion device, a flow switching valve, an accumulator, or an outdoor fan based on the control signal received through the outdoor unit communication unit. The outdoor unit may transmit a sensing value detected by an outdoor unit sensor to the control unit of the indoor unit through the outdoor unit communication unit.

[0067] The indoor unit of the air conditioner may include a housing, a blower for circulating air into or out of the housing, and an indoor heat exchanger for exchanging heat with air flowing into the interior of the housing.

[0068] The housing may include an intake port through which indoor air may be drawn into the interior of the housing.

[0069] The indoor unit of the air conditioner may include a filter that is provided to filter foreign substances in the air that flows into the housing through the intake port.

[0070] The housing may include an exhaust port. Air flowing within the housing may be discharged to the exterior of the housing through the exhaust port.

[0071] The housing of the indoor unit may be provided with an airflow guide that guides the direction of air discharged through the exhaust port. For example, the airflow guide may include blades positioned above the exhaust port. For example, the airflow guide may include an auxiliary fan for controlling the exhaust airflow. However, the airflow guide is not limited thereto and may be omitted.

[0072] An indoor heat exchanger and a blower may be provided inside the housing of the indoor unit, which are arranged on a path connecting the intake and exhaust ports.

[0073] Blowers may include indoor fans and fan motors. For example, indoor fans may include axial fans, diffusion fans, crossflow fans, and centrifugal fans.

[0074] An indoor heat exchanger may be positioned between the blower and the exhaust, or between the intake and the blower. The indoor heat exchanger may absorb heat from air drawn in through the intake or transfer heat to the air drawn in through the intake. The indoor heat exchanger may include heat exchange tubes through which refrigerant flows, and heat exchange fins in contact with the heat exchange tubes to increase the heat transfer surface area.

[0075] The indoor unit of the air conditioner may include a drain tray positioned below the indoor heat exchanger to collect condensate generated in the indoor heat exchanger. The condensate collected in the drain tray may be drained to the outside through a drain hose. The drain tray may be provided to support the indoor heat exchanger.

[0076] The indoor unit of the air conditioner may include an input interface. The input interface may include any type of user input means, including buttons, switches, a touch screen, and / or a touch pad. The user can directly input setting data (e.g., desired indoor temperature, operating mode settings for cooling / heating / dehumidification / air purification, outlet selection settings, and / or air flow settings) through the input interface.

[0077] The input interface may also be connected to an external input device. For example, the input interface may be electrically connected to a wired remote controller. The wired remote controller may be installed at a specific location in an indoor space (e.g., a portion of a wall). A user may input configuration data regarding the operation of the air conditioner by operating the wired remote controller. Electrical signals corresponding to the configuration data obtained through the wired remote controller may be transmitted to the input interface. In addition, the input interface may include an infrared sensor. A user may remotely input configuration data regarding the operation of the air conditioner using a wireless remote controller. The configuration data input through the wireless remote controller may be transmitted to the input interface as an infrared signal.

[0078] Additionally, the input interface may include a microphone. A user's voice command may be acquired through the microphone. The microphone may convert the user's voice command into an electrical signal and transmit the converted electrical signal to an indoor unit control unit. The indoor unit control unit may control components of the air conditioner to execute a function corresponding to the user's voice command. Setting data acquired through the input interface (e.g., desired indoor temperature, operation mode settings for cooling / heating / dehumidification / air purification, outlet selection settings, and / or air volume settings) may be transmitted to the indoor unit control unit, which will be described later. In one example, the setting data acquired through the input interface may be transmitted externally, i.e., to an outdoor unit or a server, through an indoor unit communication unit, which will be described later.

[0079] The indoor unit of the air conditioner may include a power module. The power module may be connected to an external power source to supply power to components of the indoor unit.

[0080] An indoor unit of an air conditioner may include an indoor unit sensor. The indoor unit sensor may be an environmental sensor positioned in a space inside or outside the housing. For example, the indoor unit sensor may include one or more temperature sensors and / or humidity sensors positioned in a predetermined space inside or outside the housing of the indoor unit. For example, the indoor unit sensor may include a refrigerant temperature sensor for detecting a refrigerant temperature of a refrigerant pipe passing through the indoor unit. For example, the indoor unit sensor may include respective refrigerant temperature sensors for detecting the inlet, middle, and / or outlet temperatures of the refrigerant pipe passing through the indoor heat exchanger.

[0081] For example, each environmental information detected by an indoor unit sensor can be transmitted to the indoor unit control unit described later or transmitted externally through the indoor unit communication unit described later.

[0082] The indoor unit of the air conditioner may include an indoor unit communication unit. The indoor unit communication unit may include at least one of a short-range communication module and a long-range communication module. The indoor unit communication unit may include at least one antenna for wireless communication with other devices. The outdoor unit may include an outdoor unit communication unit. The outdoor unit communication unit may also include at least one of a short-range communication module and a long-range communication module.

[0083] The short-range wireless communication module may include, but is not limited to, a Bluetooth communication module, a BLE (Bluetooth Low Energy) communication module, a near field communication module, a WLAN (Wi-Fi) communication module, a Zigbee communication module, an infrared (IrDA, infrared Data Association) communication module, a WFD (Wi-Fi Direct) communication module, an UWB (ultrawideband) communication module, an Ant+ communication module, a microwave (uWave) communication module, etc.

[0084] The long-distance communication module may include a communication module that performs various types of long-distance communication and may include a mobile communication unit. The mobile communication unit transmits and receives wireless signals with at least one of a base station, an external terminal, and a server on a mobile communication network.

[0085] The indoor unit communication unit can communicate with external devices such as servers, mobile devices, and other home appliances through a nearby access point (AP). The access point (AP) can connect a local area network (LAN) to which the air conditioner or user device is connected to a wide area network (WAN) to which the server is connected. The air conditioner or user device can be connected to the server through the wide area network (WAN). The indoor unit of the air conditioner may include an indoor unit control unit that controls components of the indoor unit, including a blower, etc. The outdoor unit of the air conditioner may include an outdoor unit control unit that controls components of the outdoor unit, including a compressor, etc. The indoor unit control unit can communicate with the outdoor unit control unit through the indoor unit communication unit and the outdoor unit communication unit. The outdoor unit communication unit can transmit control signals generated by the outdoor unit control unit to the indoor unit communication unit, or transmit control signals transmitted from the indoor unit communication unit to the outdoor unit control unit. In other words, the outdoor unit and the indoor unit can communicate bidirectionally. The outdoor unit and the indoor unit can transmit and receive various signals generated during the operation of the air conditioner.

[0086] The outdoor unit control unit can be electrically connected to components of the outdoor unit and can control the operation of each component. For example, the outdoor unit control unit can adjust the frequency of the compressor and control the flow switching valve to change the circulation direction of the refrigerant. The outdoor unit control unit can adjust the rotation speed of the outdoor fan. In addition, the outdoor unit control unit can generate a control signal to adjust the opening degree of the expansion valve. Under the control of the outdoor unit control unit, the refrigerant can circulate along a refrigerant circulation circuit including the compressor, the flow switching valve, the outdoor heat exchanger, the expansion valve, and the indoor heat exchanger.

[0087] The various temperature sensors included in the outdoor and indoor units can transmit electrical signals corresponding to the detected temperatures to the outdoor unit control unit and / or the indoor unit control unit. For example, the humidity sensors included in the outdoor and indoor units can transmit electrical signals corresponding to the detected humidity to the outdoor unit control unit and / or the indoor unit control unit.

[0088] The indoor unit control unit can obtain user input from a user device, including a mobile device, via the indoor unit communication unit, and can obtain user input directly through the input interface or via a remote controller. The indoor unit control unit can control components of the indoor unit, including a blower, in response to the received user input. The indoor unit control unit can transmit information regarding the received user input to the outdoor unit control unit of the outdoor unit.

[0089] The outdoor unit control unit can control the components of the outdoor unit, including the compressor, based on information regarding user input received from the indoor unit. For example, when a control signal corresponding to a user input for selecting an operation mode, such as cooling operation, heating operation, ventilation operation, defrosting operation, or dehumidification operation, is received from the indoor unit, the outdoor unit control unit can control the components of the outdoor unit so that the air conditioner performs an operation corresponding to the selected operation mode.

[0167] Referring to FIG. 6, in the exhaust device (100) of the air conditioner (1) according to one embodiment of the present disclosure, a discharge cover (110) and a switching member (130) may be arranged on the outside of a rotation transmission part (140) centered on the rotation axis of the exhaust fan (161), a movable support member (106) and a movable cover (150) may be arranged on the outside of the discharge cover (110) and the switching member (130), and a rotation member (120) may be arranged on the outside of the movable support member (106) and the movable cover (150).

[0168] FIG. 7 illustrates an exhaust device according to one embodiment of the present disclosure with its exhaust port closed. FIG. 8 illustrates a coupling relationship between components related to the movement of the exhaust cover when the exhaust device according to one embodiment of the present disclosure has its exhaust port closed. FIG. 9 illustrates an airflow inside a housing when the exhaust device according to one embodiment of the present disclosure has its exhaust port closed.

[0169] Referring to FIGS. 7 and 8, a state in which a discharge device (100) according to one embodiment of the present disclosure has its discharge port (16a) closed is described.

[0170] Referring to FIGS. 7 and 8, the discharge device (100) may be configured to close the discharge port (16a). At this time, the discharge cover (110) may be positioned at a first position (P1) configured to close the discharge port (16a). That is, when the discharge cover (110) is at the first position (P1), the discharge cover (110) may close the discharge port (16a). When the discharge cover (110) is at the first position (P1), the cover opening (117) may be positioned inside the housing (10).

[0171] When the discharge cover (110) is in the first position (P1), the movable coupling part (133) of the switching member (130) may be located at the bottom of the movable guide (123) of the rotating member (120). The movable coupling part (133) of the switching member (130) may be located at the bottom of the movable support part (106).

[0172] Referring to FIG. 9, the air flow inside the housing (10) is described when the discharge device (100) according to one embodiment of the present disclosure has the discharge port (16a) closed (i.e., when the discharge cover (110) is in the first position (P1)).

[0173] When the exhaust cover (110) is in the first position (P1), the blower (30) may operate, but the exhaust fan (161) may not operate. Accordingly, the air flow inside the housing (10) may be formed only by the blower (30).

[0174] A first flow path (F1) may be formed within the housing (10) by a blower (30). Air blown by the blower (30) may flow into the first flow path (F1). The first flow path (F1) may extend from an inlet (13a) to an outlet (13b). Specifically, the first flow path (F1) may be a flow path in which air introduced into the housing (10) through the inlet (13a) and the inlet opening (14) sequentially passes through a dust collector (50), a deodorizer (40), and a blower (30), and is discharged through a discharge portion (13b) and the outlet opening (15). The air flowing into the first flow path (F1) may be filtered by the dust collector (50) and deodorized by the deodorizer (40). That is, contaminated air that has entered the housing (10) through the inlet (13a) can be discharged through the outlet (13b) in a purified state by the dust collector (50) and the deodorizing device (40).

[0175] Air flowing in the first direction (F1) can flow along a first direction (D1) within the housing (10). For example, the first direction (D1) within the housing (10) can include a vertical direction (Z direction).

[0176] The first direction (D1) may be a direction in which air introduced into the housing (10) through the inlet (13a) and the inlet opening (14) flows toward the discharge opening (15) and the discharge portion (13b). For example, the first direction (D1) may be a direction in which air introduced into the housing (10) through the inlet (13a) and the inlet opening (14) passes through the dust collector (50), the deodorizing device (40), and the blower (30). For example, the first direction (D1) may be upward. For example, air introduced to the front, rear, left, and right sides through the inlet (13a) of the housing (10) by the blower (30) may flow along the first direction (D1) within the housing (10) and then be discharged to the front, rear, left, and right sides through the discharge portion (13b) of the housing (10).

[0177] FIG. 10 illustrates an exhaust device according to one embodiment of the present disclosure with its exhaust port open. FIG. 11 illustrates a coupling relationship between components related to movement of the exhaust cover in an exhaust device according to one embodiment of the present disclosure with its exhaust port open. FIG. 12 illustrates airflow inside a housing in an exhaust device according to one embodiment of the present disclosure with its exhaust port closed.

[0178] Referring to FIGS. 10 to 12, a state in which a discharge device (100) according to one embodiment of the present disclosure opens a discharge port (16a) is described.

[0179] Referring to FIGS. 10 to 12, the discharge device (100) may be configured to open the discharge port (16a). At this time, the discharge cover (110) may be positioned at a second position (P2) configured to open the discharge port (16a). That is, when the discharge cover (110) is at the second position, the discharge cover (110) may open the discharge port (16a). When the discharge cover (110) is at the second position (P2), at least a portion of the cover opening (117) may be positioned outside the housing (10).

[0180] When the discharge cover (110) is in the second position (P2), the movable coupling part (133) of the switching member (130) can be located above the movable guide (123) of the rotating member (120). The movable coupling part (133) of the switching member (130) can be located above the movable support part (106).

[0181] Specifically, the discharge device (100) according to one embodiment of the present disclosure may be configured such that the rotating member (120) rotates as the moving driving source (102) operates, the switching member (130) rotates and moves upward as the rotating member (120) rotates, and the discharge cover (110) moves upward without rotation as the switching member (130) rotates and moves upward to open the discharge port (16a).

[0182] As the rotating member (120) rotates, the movable coupling part (133) inserted into the moving guide (123) of the rotating member (120) moves in the direction of rotating the switching member (130). While the movable coupling part (133) moves in the direction of rotating the switching member (130), the movable coupling part (133) moves on the moving support part (106), and since the movable support part (106) has an upwardly inclined shape, the movable coupling part (133) moves upward. As the movable coupling part (133) moves upward, the discharge cover (110) that is coupled to move up and down together with the switching member (130) moves upward. At this time, the discharge cover (110) moves upward without rotating.

[0183] The discharge cover (110) according to one embodiment of the present disclosure may be movable to a first position (P1) and a second position (P2).

[0184] For example, the discharge cover (110) can be positioned at a first position (P1) or a second position (P2) by moving in the up-and-down direction (Z direction) with respect to the base (101). For example, when the discharge cover (110) is at the first position (P1), the discharge cover (110) can be arranged to be able to move upward to the second position (P2). For example, when the discharge cover (110) is at the second position (P2), the discharge cover (110) can be arranged to be able to move downward to the first position (P1).

[0185] For example, the discharge cover (110) can be positioned at a first position (P1) or a second position (P2) by moving in a first direction (D1) or in a direction opposite to the first direction (D1) with respect to the base (101). For example, when the discharge cover (110) is at the first position (P1), the discharge cover (110) can be arranged to be movable along the first direction (D1) toward the second position (P2). For example, when the discharge cover (110) is at the second position (P2), the discharge cover (110) can be arranged to be movable along a direction opposite to the first direction (D1) toward the first position (P1).

[0186] When the discharge cover (110) according to one embodiment of the present disclosure moves from the second position (P2) to the first position (P1), the above-described process may be performed in reverse. Specifically, when the moving drive source (102) generates a rotational force in the opposite direction to that when raising the discharge cover (110), the rotational member (120) rotates, and as the rotational member (120) rotates, the switching member (130) rotates and moves downward, and as the switching member (130) rotates and moves downward, the discharge cover (110) may be configured to move downward without rotation and close the discharge port (16a).

[0187] Referring to FIG. 12, the air flow inside the housing (10) is described when the discharge device (100) according to one embodiment of the present disclosure has the discharge port (16a) open (i.e., when the discharge cover (110) is in the second position (P2)).

[0188] When the exhaust cover (110) is in the second position (P2), both the blower (30) and the exhaust fan (161) can operate. Accordingly, the air flow inside the housing (10) can be formed by the blower (30) and the exhaust fan (161).

[0189] When the exhaust cover (110) is in the second position (P2), some of the air flowing to the exhaust portion (13b) by the blower (30) may be discharged through the exhaust port (16a) by the exhaust fan (161). In addition, some of the air flowing to the exhaust portion (13b) by the blower (30) may be discharged through the exhaust portion (13b).

[0190] Specifically, a separation space (60) may be formed between the blower (30) and the exhaust fan (161). The blower (30) may be provided to blow air toward the separation space (60). An exhaust fan (161) may be provided on an upper side of the separation space (60). An exhaust port (13b) may be provided on one side of the separation space (60). According to this configuration, some of the air blown toward the separation space (60) by the blower (30) may be introduced into the exhaust device (100) by the exhaust fan (161) and discharged through the exhaust port (16a), and other some of the air blown toward the separation space (60) by the blower (30) may be discharged through the exhaust port (13b).

[0191] Within the housing (10), a first flow path (F1) may be formed by a blower (30), and a second flow path (F2) may be formed by an exhaust fan (161). Air blown by the exhaust fan (161) may flow to the second flow path (F2). The second flow path (F2) may extend from the separation space (60) to the cover opening (117). Specifically, the second flow path (F2) may be a flow path through which air, which is introduced into the exhaust device (100) from the separation space (60) through the exhaust fan (161), passes through the grill (142) and the exhaust port (16a) of the rotating transmission part (140), and is exhausted through the cover opening (117) of the exhaust cover (110).

[0192] The second flow path (F2) may be formed by branching off from the first flow path (F1). The second flow path (F2) may be formed by branching off from the first flow path (F1) in the separation space (60). That is, the air that flows into the housing (10) through the inlet (13a) and into the first flow path (F1) may be branched off into the second flow path (F2) in the separation space (60). Since the air that flows into the first flow path (F1) may be purified by the dust collector (50) and the deodorizer (40), the air that branches off into the second flow path (F2) and flows into the exhaust device (100) may be purified air.

[0193] An exhaust fan (161) according to one embodiment of the present disclosure may be fixed inside the housing (10). Specifically, the exhaust fan (161) may be fixed between the blower (30) and the exhaust port (16a). Through this configuration, when the exhaust cover (110) is at the second position (P2), the exhaust fan (161) may be arranged to exhaust air through the exhaust port (16a). In addition, since the exhaust fan (161) is fixed inside the housing (10) while the exhaust cover (110) moves from the first position (P1) to the second position (P2), it is possible to limit or prevent contaminated air outside the housing (10) from being introduced into the exhaust device (100) by the exhaust fan (161). That is, when discharging air through the exhaust device (100), it is possible to limit or prevent polluted indoor air from being discharged by mixing with the air purified by the dust collector (50) and the deodorizing device (40).

[0194] According to one embodiment of the present disclosure, the flow rate of the exhaust fan (161) may be set to be 50% or less of the flow rate of the blower (30). For example, the diameter of the exhaust fan (161) may be set to be 0.8 to 0.9 times the diameter of the blower (30). Through this configuration, when the exhaust fan (161) operates, the blowing force of the exhaust fan (161) can limit or prevent contaminated indoor air from passing through the exhaust portion (13b) and flowing into the exhaust device (100).

[0195] The air flowing in the second direction (F2) can flow along a first direction (D1) or a second direction (D2) within the exhaust device (100). The second direction (D2) may be a direction intersecting the first direction (D1). For example, within the exhaust device (100), the first direction (D1) may include a vertical direction (Z direction), and the second direction (D2) may include a horizontal direction (direction on the XY plane).

[0196] The first direction (D1) may be a direction in which air drawn into the exhaust device (100) through the exhaust fan (161) flows toward the exhaust cover (110). For example, the first direction (D1) may be a direction in which air drawn into the exhaust device (100) through the exhaust fan (161) passes through the grill (142) of the rotating transmission part (140) and the exhaust port (16a). For example, the first direction (D1) may be upward. Air flowing along the first direction (D1) within the exhaust device (100) may flow into the exhaust cover (110).

[0197] The second direction (D2) may be the direction in which air flowing into the exhaust cover (110) faces the cover opening (117). The air flowing along the first direction (D1) may have its flow direction changed inside the exhaust cover (110). The air whose flow direction has been changed inside the exhaust cover (110) may be discharged through the cover opening (117). At this time, the air discharged through the cover opening (117) may flow along the second direction (D2).

[0198] According to one embodiment of the present disclosure, the cover opening (117) may be provided to open in a direction intersecting the direction in which the discharge cover (110) moves.

[0199] For example, the exhaust cover (110) can move in the up-and-down direction (Z direction), and the cover opening (117) can open in the horizontal direction (direction on the XY plane). Accordingly, the air exhausted through the cover opening (117) can be directed in the horizontal direction.

[0200] For example, the exhaust cover (110) can move in the first direction (D1) or in the opposite direction to the first direction (D1), and the cover opening (117) can be opened toward the second direction (D2). Accordingly, air discharged through the cover opening (117) can be directed toward the second direction (D2).

[0201] FIG. 13 is an exploded view of a discharge cover according to one embodiment of the present disclosure. FIG. 14 is an exploded view of a discharge cover according to one embodiment of the present disclosure. FIG. 15 is a cross-sectional view of a cover frame according to one embodiment of the present disclosure. FIG. 16 is a cross-sectional view of a cover frame according to one embodiment of the present disclosure.

[0202] Referring to FIGS. 12 to 16, the detailed configuration of the discharge cover (110) according to one embodiment of the present disclosure will be described.

[0203] Referring to FIGS. 12 to 16, the exhaust fan (161) can blow air in a first direction (D1) toward the exhaust port (16a). The air drawn into the exhaust cover (110) can have its flow direction changed to blow air in a second direction (D2). Specifically, the air inside the exhaust cover (110) can be discharged through the cover opening (117) and flow along the second direction (D2).

[0204] The exhaust cover (110) may include an airflow diverting part (115). The airflow diverting part (115) may be provided to divert the direction of air blown by the exhaust fan (161). For example, air flowing in the first direction (D1) by the exhaust fan (161) may have its flow direction diverted by the airflow diverting part (115).

[0205] The airflow diversion unit (115) may include an extending portion (115a) extending along the first direction (D1). That is, the extending portion (115a) may extend in the same direction as the moving direction of the exhaust cover (110). The extending portion (115a) may be provided at the center of the airflow diversion unit (115). The extending portion (115a) may guide air flowing in the first direction (D1) by the exhaust fan (161).

[0206] The airflow diversion portion (115) may include a top surface portion (115b) extending radially from the upper end of the extension portion (115a). The top surface portion (115b) may be formed by bending from the upper end of the extension portion (115a). Air guided by the extension portion (115a) may reach the top surface portion (115b) and its flow direction may be converted.

[0207] The exhaust cover (110) may include a side wall part (116). The side wall part (116) may extend from the edge of the airflow diversion part (115) along the first direction (D1). That is, the side wall part (116) may extend from the edge of the airflow diversion part (115) in the same direction as the movement direction of the exhaust cover (110).

[0208] A cover opening (117) may be provided in a portion of the side wall portion (116). For example, the size of the cover opening (117) may be provided to be 30% or less of the overall size of the side wall portion (116). However, the size of the cover opening (117) is not limited thereto.

[0209] The side wall portion (116) can guide air within the exhaust cover (110) to the cover opening (117). That is, air whose flow direction has been changed by reaching the upper surface portion (115b) of the airflow conversion portion (115) can be guided by the side wall portion (116) and flow toward the cover opening (117). The air flowing toward the cover opening (117) can be discharged through the cover opening (117).

[0210] The airflow diversion unit (115) may include a first guiding portion (115c) extending in a second direction (D2) to guide air discharged through the cover opening (117). That is, the first guiding portion (115c) may extend in a direction intersecting with the direction in which the discharge cover (110) moves. The first guiding portion (115c) may be formed on a portion of the outer circumferential surface of the upper surface (115b). Specifically, the first guiding portion (115c) may be formed on the upper side of the cover opening (117).

[0211] The side wall portion (116) may include a second guiding portion (116a) extending in a second direction (D2) to guide air discharged through the cover opening (117). That is, the second guiding portion (116a) may extend in a direction intersecting with the direction in which the discharge cover (110) moves. The second guiding portion (116a) may be formed on a portion of the side wall portion (116). Specifically, the second guiding portion (116a) may be formed on both sides of the cover opening (117).

[0212] According to one embodiment of the present disclosure, the first guide portion (115c) and the second guide portion (116a) may be formed along the edge of the cover opening (117). Since the first guide portion (115c) and the second guide portion (116a) each extend along the second direction (D2), air discharged through the cover opening (117) may flow toward the second direction (D2). That is, since the air discharged through the cover opening (117) flows in the same direction, air may be precisely directed to a desired point, and the air flow distance may also be increased.

[0213] The airflow diversion unit (115) and the side wall unit (116) according to one embodiment of the present disclosure may be formed integrally. For example, the exhaust cover (110) may include a cover frame (112) having the airflow diversion unit (115) and the side wall unit (116).

[0214] The discharge cover (110) may include a top cover (113). The top cover (113) may be coupled to the upper surface of the cover frame (112) so as to cover the upper surface of the cover frame (112). Specifically, the top cover (113) may be coupled to the upper surface of the cover frame (112) by coupling the top cover coupling portion (113a) provided on the lower surface of the top cover (113) with the first cover frame coupling portion (112a) provided on the upper surface of the cover frame (112).

[0215] The discharge cover (110) may include a side cover (114). The side cover (114) may be coupled to a side of the cover frame (112) to cover the side of the cover frame (112). Specifically, the side cover (114) may be coupled to the side of the cover frame (112) by coupling a side cover coupling portion (114a) provided at the lower portion of the side cover (114) with a second cover frame coupling portion (112b) provided at the lower portion of the cover frame (112).

[0216] Fig. 17 illustrates a state in which the discharge cover of an exhaust device according to one embodiment of the present disclosure is rotated. Fig. 18 illustrates a coupling relationship between components related to the rotation of the discharge cover in a state in which the discharge port of an exhaust device according to one embodiment of the present disclosure is opened. Fig. 19 illustrates a coupling relationship between components related to the rotation of the discharge cover in a state in which the discharge cover of an exhaust device according to one embodiment of the present disclosure is rotated.

[0217] Referring to FIG. 14 and FIG. 17 to FIG. 19, the operation of rotating the discharge cover (110) of the discharge device (100) according to one embodiment of the present disclosure will be described.

[0218] The discharge cover (110) of the discharge device (100) according to one embodiment of the present disclosure can be rotated from the state shown in FIGS. 14 and 18 to the state shown in FIGS. 17 and 19.

[0219] Specifically, as the rotation drive source (103) operates, the rotation transmission part (140) rotates, and as the rotation transmission part (140) rotates, the discharge cover (110) rotates without moving. Since the switching member (130) is provided to be rotatable with respect to the discharge cover (110), even if the discharge cover (110) rotates, the switching member (130) may not rotate.

[0220] In order to rotate the discharge cover (110) of the discharge device (100) according to one embodiment of the present disclosure from the state illustrated in FIGS. 17 and 19 to the state illustrated in FIGS. 14 and 18, the above-described process can be performed in reverse. Specifically, the rotational driving source (103) can generate a rotational force in a direction opposite to the above-described direction, and accordingly, the rotational transmission part (140) and the discharge cover (110) can rotate in the opposite directions.

[0221] As the exhaust cover (110) according to one embodiment of the present disclosure rotates, the direction of flow of air discharged through the cover opening (117) of the exhaust cover (110) can change. That is, a user of the air conditioner (1) can rotate the exhaust cover (110) to blow purified air in a desired direction.

[0222] According to this configuration, the air conditioner (1) according to one embodiment of the present disclosure can guide a portion of the air blown toward the discharge portion (13b) to the discharge port (16a) and discharge it in various ways.

[0223] An air conditioner (1) according to one embodiment comprises a housing (10) including an inlet portion (13a), an outlet portion (13b), and an outlet port (16a), a blower (30) for circulating air into or out of the housing (10), and an exhaust device (100) for guiding a portion of air flowing to the outlet portion (13b) by the blower (30) to the exhaust port (16a). The exhaust device (100) further comprises a discharge cover (110) movable to a first position (P1) configured to close the exhaust port (16a) and a second position (P2) configured to open the exhaust port (16a), and an exhaust fan (161) fixed inside the housing (10) to exhaust air through the exhaust port (16a) when the exhaust cover (110) is in the second position (P2).

[0224] When the above discharge cover (110) is at the second position (P2), some of the air flowing to the discharge portion (13b) by the blower (30) can be discharged through the discharge port (16a) by the discharge fan (161), and other some of the air flowing to the discharge portion (13b) by the blower (30) can be discharged through the discharge portion (13b).

[0225] A separation space (60) may be formed between the blower (30) and the exhaust fan (161). The blower (30) may be capable of blowing air toward the separation space (60). The exhaust portion (13b) may be provided on one side of the separation space (60).

[0226] The above discharge cover (110) may include a cover opening (117) that is provided to open in a direction intersecting the direction in which the discharge cover (110) moves when the discharge cover (110) is at the second position (P2).

[0227] The cover opening (117) may be located inside the housing (10) when the discharge cover (110) is in the first position (P1). At least a portion of the cover opening (117) may be located outside the housing (10) when the discharge cover (110) is in the second position (P2).

[0228] The above exhaust cover (110) may further include an airflow conversion part (115) provided to change the direction of air blown by the exhaust fan (161) and a side wall part (116) extending from the edge of the airflow conversion part (115) in the same direction as the movement direction of the exhaust cover (110). The cover opening (117) may be formed in a portion of the side wall part (116).

[0229] The airflow switching portion (115) may include a first guide portion (115c) extending in one direction to guide air discharged through the cover opening (117). The side wall portion (116) may include a second guide portion (116a) extending in one direction to guide air discharged through the cover opening (117). The first guide portion (115c) and the second guide portion (116a) may be formed along the edge of the cover opening (117).

[0230] The above discharge cover (110) may be rotatable.

[0231] The above discharge cover (110) can be rotated around a virtual rotation axis (L) extending in the same direction as the movement direction of the above discharge cover (110).

[0232] The above discharge device (100) may further include a base (101) portion fixed to the housing (10). The discharge cover (110) may be movable and rotatable with respect to the base (101).

[0233] The above discharge device (100) may further include a rotational transmission part (140) that is rotatable relative to the base (101). The discharge cover (110) may be coupled to the rotational transmission part (140) so as to be rotatable together with the rotational transmission part (140).

[0234] The rotation transmission part (140) may be restricted from moving in the direction of movement of the discharge cover (110). The discharge cover (110) may be movably coupled to the rotation transmission part (140).

[0235] The above-mentioned rotation transmission part (140) may further include a grill (142) provided to allow air flowing toward the discharge port (16a) to pass when the discharge cover (110) is at the second position (P2).

[0236] The above discharge cover (110) can be moved up and down.

[0237] The above discharge cover (110) can be moved upward to the second position (P2) when it is in the first position (P1), and can be moved downward to the first position (P1) when it is in the second position (P2).
