[0041] When it is said that a component is located "on" another component, this includes not only cases where one component is in contact with the other, but also cases where another component exists between the two components.

[0042] 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 having at least one of these functions.

[0043] According to one embodiment, an air conditioner may include a heat pump device to perform a cooling or 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 that forms the exterior of the air conditioner, such as a window air conditioner or a portable air conditioner. Alternatively, some components of the heat pump device may be housed separately in multiple housings that form a single air conditioner, such as a wall-mounted air conditioner, a stand-type air conditioner, or a system air conditioner.

[0044] An air conditioner comprising 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 refrigerant pipes. For example, the air conditioner may be configured such that one outdoor unit is connected via refrigerant pipes to two or more indoor units. 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.

[0045] The outdoor unit can be electrically connected to the indoor unit. For example, information (or commands) for controlling the air conditioner can be entered through an input interface provided on the outdoor unit or the indoor unit, and the outdoor unit and the indoor unit can operate simultaneously or sequentially in response to user input.

[0046] 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.

[0047] An outdoor heat exchanger can perform heat exchange between the refrigerant and the outdoor air by utilizing the phase change of the refrigerant (e.g., evaporation or condensation). For example, while the refrigerant condenses in the outdoor heat exchanger, the refrigerant releases heat to the outdoor air, and while the refrigerant flowing through the outdoor heat exchanger evaporates, the refrigerant can absorb heat from the outdoor air.

[0048] Indoor units are installed indoors. For example, indoor units can be classified into ceiling-mounted, stand-type, and wall-mounted units depending on how they are placed. For example, ceiling-mounted indoor units can be classified into 4-way, 1-way, and duct-type units depending on the method of air discharge.

[0049] Similarly, an indoor heat exchanger can perform heat exchange between the refrigerant and the indoor air by utilizing the phase change of the refrigerant (e.g., evaporation or condensation). For example, while the refrigerant evaporates in the indoor unit, it can absorb heat from the indoor air, and the room can be cooled by blowing the cooled indoor air as it passes through the cooled indoor heat exchanger. Additionally, while the refrigerant condenses in the indoor heat exchanger, it can release heat to the indoor air, and the room can be heated by blowing the heated indoor air as it passes through the high-temperature indoor heat exchanger.

[0050] In other words, an air conditioner performs cooling or heating functions through the phase change process of a refrigerant circulating between an outdoor heat exchanger and an indoor heat exchanger; to facilitate this refrigerant circulation, the air conditioner may include a compressor that compresses the refrigerant. The compressor can draw in refrigerant gas through a suction port and compress the refrigerant gas. The compressor can discharge high-temperature, high-pressure refrigerant gas through a discharge port. The compressor may be placed inside the outdoor unit.

[0051] The refrigerant may circulate through the refrigerant pipe in the order of the compressor, outdoor heat exchanger, expansion device, and indoor heat exchanger, or in the order of the compressor, indoor heat exchanger, expansion device, and outdoor heat exchanger.

[0052] For example, if an air conditioner has one outdoor unit and one indoor unit directly connected through a refrigerant pipe, the refrigerant can be arranged to circulate between the outdoor unit and the indoor unit through the refrigerant pipe.

[0053] For example, in an air conditioner, if one outdoor unit is connected to two or more indoor units via refrigerant pipes, the refrigerant may flow to multiple indoor units through refrigerant pipes branching from the outdoor unit. The refrigerant discharged from multiple indoor units may be combined and circulated back to the outdoor unit. For example, multiple indoor units may each be directly connected in parallel to a single outdoor unit via separate refrigerant pipes.

[0054] Multiple indoor units can each operate independently according to an operating mode set by the user. That is, some of the multiple indoor units can operate in cooling mode while others operate in heating mode simultaneously. In this case, the refrigerant may be arranged to flow into each indoor unit in a selectively high-pressure or low-pressure state along a designated circulation path via a flow path switching valve to be described later, and to be discharged and circulated to the outdoor unit.

[0055] For example, when two or more outdoor units and two or more indoor units are connected through multiple refrigerant pipes, the refrigerant discharged from multiple outdoor units may be combined and flow through a single refrigerant pipe, and then branch out again at some point to flow into multiple indoor units.

[0056] Multiple outdoor units may all be driven or at least some may not be driven, depending on the operating load corresponding to the operating amount of multiple indoor units. In this case, the refrigerant may be arranged to flow into and circulate to the outdoor units that are selectively driven through a flow path switching valve. The air conditioner may include an expansion device to lower the pressure of the refrigerant flowing into the heat exchanger. For example, the expansion device may be placed inside the indoor unit or inside the outdoor unit, or it may be placed in both.

[0057] For example, an expansion device can lower the temperature and pressure of the refrigerant by utilizing a throttling effect. The expansion device may include an orifice that can reduce the cross-sectional area of ​​the flow path. The temperature and pressure of the refrigerant passing through the orifice can be lowered.

[0058] The expansion device can be implemented, for example, as an electronic expansion valve capable of controlling the opening ratio (the ratio of the cross-sectional area of ​​the valve's flow path in the partially open state to the cross-sectional area of ​​the valve's flow path in the fully open state). The amount of refrigerant passing through the expansion device can be controlled depending on the opening ratio of the electronic expansion valve.

[0059] The air conditioner may further include a flow switching valve positioned on the refrigerant circulation path. The flow switching valve may include, for example, a 4-way valve. The flow switching valve can determine the refrigerant circulation path depending on the operating mode of the indoor unit (e.g., cooling operation or heating operation). The flow switching valve may be connected to the discharge port of the compressor.

[0060] The air conditioner may include an accumulator. The accumulator may be connected to the suction port of the compressor. Low-temperature, low-pressure refrigerant evaporated from an indoor heat exchanger or an outdoor heat exchanger may be introduced into the accumulator.

[0061] The accumulator can separate the refrigerant liquid from the refrigerant gas when the refrigerant mixed with the refrigerant gas is introduced, and supply the refrigerant gas from which the refrigerant liquid has been separated to the compressor.

[0062] An outdoor fan may be provided near the outdoor heat exchanger. The outdoor fan can blow outdoor air onto the outdoor heat exchanger to facilitate heat exchange between the refrigerant and the outdoor air.

[0063] 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 environment sensor. The outdoor unit sensor may be placed at any location inside or outside the outdoor unit. For example, the outdoor unit sensor may include, for instance, 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 the refrigerant pipe passing through the outdoor unit, or a refrigerant pressure sensor for detecting the refrigerant pressure of the refrigerant pipe passing through the outdoor unit.

[0064] The outdoor unit of the air conditioner may include an outdoor unit communication unit. The outdoor unit communication unit may be configured to receive control signals from the control unit of the indoor unit of the air conditioner, which will be described later. Based on the control signals received through the outdoor unit communication unit, the outdoor unit may control the operation of the compressor, outdoor heat exchanger, expansion device, flow path switching valve, accumulator, or outdoor fan. The outdoor unit may transmit a sensing value detected by the outdoor unit sensor to the control unit of the indoor unit through the outdoor unit communication unit.

[0065] The indoor unit of an air conditioner may include a housing, a blower that circulates air inside or outside the housing, and an indoor heat exchanger that exchanges heat with the air flowing into the housing.

[0066] The housing may include an intake port. Indoor air can be drawn into the interior of the housing through the intake port.

[0067] The indoor unit of the air conditioner may include a filter configured to filter foreign substances in the air entering the housing through the intake port.

[0068] The housing may include an outlet. Air flowing inside the housing can be discharged to the outside of the housing through the outlet.

[0069] The housing of the indoor unit may be provided with an airflow guide that guides the direction of air discharged through the outlet. For example, the airflow guide may include a blade located above the outlet. For example, the airflow guide may include an auxiliary fan for controlling the discharge airflow. The airflow guide may be omitted, but is not limited thereto.

[0070] An indoor heat exchanger and a blower may be provided inside the housing of the indoor unit, positioned on the path connecting the intake and exhaust ports.

[0071] The blower may include an indoor fan and a fan motor. For example, the indoor fan may include an axial fan, a mixed-flow fan, a cross-flow fan, or a centrifugal fan.

[0072] The indoor heat exchanger may be positioned between the blower and the outlet, or between the intake and the blower. The indoor heat exchanger may absorb heat from the air entering through the intake or transfer heat to the air entering 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.

[0073] The indoor unit of the air conditioner may include a drain tray positioned below the indoor heat exchanger to collect condensate generated from the indoor heat exchanger. The condensate contained 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.

[0074] 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, touch screens, and / or touch pads. The user can directly input setting data (e.g., desired indoor temperature, setting of operating mode for cooling / heating / dehumidification / air purification, setting of outlet selection, and / or setting of airflow) through the input interface.

[0075] The input interface may 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 within the indoor space (e.g., a part of a wall). The user can input setting data regarding the operation of the air conditioner by operating the wired remote controller. An electrical signal corresponding to the setting data obtained through the wired remote controller may be transmitted to the input interface. Additionally, the input interface may include an infrared sensor. The user can input setting data regarding the operation of the air conditioner remotely using a wireless remote controller. The setting data input through the wireless remote controller may be transmitted to the input interface as an infrared signal.

[0076] 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 the indoor unit control unit. The indoor unit control unit may control the components of the air conditioner to execute functions corresponding to the user's voice command. Setting data acquired through the input interface (e.g., desired indoor temperature, operating mode settings for cooling / heating / dehumidification / air purification, outlet selection settings, and / or airflow settings) may be transmitted to the indoor unit control unit described later. In one example, the setting data acquired through the input interface may be transmitted externally, namely to an outdoor unit or a server, through the indoor unit communication unit described later.

[0077] The indoor unit of the air conditioner may include a power module. The power module can be connected to an external power source to supply power to the components of the indoor unit.

[0078] The indoor unit of an air conditioner may include an indoor unit sensor. The indoor unit sensor may be an environment sensor placed 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 placed 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 the 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, intermediate, and / or outlet temperatures of a refrigerant pipe passing through an indoor heat exchanger.

[0079] For example, each environmental information detected by the indoor unit sensor may be transmitted to the indoor unit control unit described later, or transmitted to the outside through the indoor unit communication unit described later.

[0080] The indoor unit of an 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 or a long-range communication module. The indoor unit communication unit may include at least one antenna for wirelessly communicating with another device. 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 or a long-range communication module.

[0081] A 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.

[0082] 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.

[0083] The indoor unit communication unit can communicate with external devices, such as servers, mobile devices, and other home appliances, through nearby access points (APs). The access point (AP) can connect the local area network (LAN) to which the air conditioner or user device is connected to the 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 the indoor unit's components, such as a blower. The outdoor unit of the air conditioner may include an outdoor unit control unit that controls the outdoor unit's components, such as a compressor. 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.

[0084] The outdoor unit control unit can be electrically connected to the 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 path switching valve to switch the direction of refrigerant circulation. The outdoor unit control unit can adjust the rotational speed of the outdoor fan. In addition, the outdoor unit control unit can generate a control signal to adjust the opening of the expansion valve. Under the control of the outdoor unit control unit, refrigerant can circulate along a refrigerant circulation circuit including a compressor, a flow path switching valve, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger.

[0085] Various temperature sensors included in the outdoor and indoor units can each transmit an electrical signal corresponding to the detected temperature to the outdoor unit control unit and / or the indoor unit control unit. For example, humidity sensors included in the outdoor and indoor units can each transmit an electrical signal corresponding to the detected humidity to the outdoor unit control unit and / or the indoor unit control unit.

[0086] The indoor unit control unit can acquire user input from a user device, including a mobile device, through the indoor unit communication unit, and can acquire user input directly or through a remote controller via an input interface. The indoor unit control unit can control the 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.

[0087] 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 the outdoor unit control unit receives a control signal from the indoor unit corresponding to user input selecting an operation mode such as cooling operation, heating operation, fan operation, defrosting operation, or dehumidification operation, it can control the components of the outdoor unit so that the operation of the air conditioner corresponding to the selected operation mode is performed.

[0091] The indoor unit of the air conditioner may include an output interface. The output interface is electrically connected to the indoor unit control unit and can output information related to the operation of the air conditioner under the control of the indoor unit control unit. For example, information such as the operating mode, airflow direction, airflow volume, and temperature selected by user input may be output. Additionally, the output interface may output sensing information obtained from the indoor unit sensor or the outdoor unit sensor, as well as warning / error messages.

[0092] The output interface may include a display and a speaker. The speaker can output various sounds as an acoustic device. The display may display information entered by the user or information provided to the user as various graphic elements.

In other words, some of the air introduced into the main body (10) through the air inlet (14) may be discharged outside the air conditioner (1) through the air outlet (15), and other parts may pass through the body opening (210, 310) and then be discharged outside the air conditioner (1) through the humid air outlet (17).

[0172] Below, with reference to FIG. 5, the internal flow path structure of the air conditioner (1) will be explained.

[0173] First, the blower (20) can introduce air into the interior of the first body (200) through the air inlet (14). Additionally, the blower (20) can flow the air introduced into the interior of the first body (200) in a first direction (D1).

[0174] For example, the blower (20) can flow air introduced into the first body (200) upward. For example, the blower (20) can flow air introduced into the first body (200) toward the second body (300). For example, the blower (20) can flow air introduced into the first body (200) toward the inlet space (201). For example, the blower (20) can flow air introduced into the first body (200) toward the body openings (210, 310). For example, the blower (20) can flow air introduced into the first body (200) toward the air outlet (15). For example, the blower (20) can flow air introduced into the first body (200) toward the humid air outlet (17).

[0175] The blower (20) can form a first flow path (P1) by introducing air into the interior of the first body (200) through the air inlet (14) and flowing the introduced air in a first direction (D1). The first flow path (P1) can extend from outside the main body (10) through the air inlet (14) to the inlet space (201).

[0176] Some of the air flowing into the air inlet (14) through the blower (20) can be discharged through the air outlet (15), and other parts can be discharged through the body opening (210, 310) and through the humid air outlet (17). In other words, some of the air flowing from the air inlet (14) toward the second body (300) can be discharged through the air outlet (15), and other parts can be discharged through the body opening (210, 310) and through the humid air outlet (17). In other words, some of the air flowing from the air inlet (14) toward the humid air outlet (17) can be discharged through the air outlet (15), and other parts can be discharged through the body opening (210, 310) and through the humid air outlet (17).

[0177] The blower (20) can form a second flow path (P2) by discharging a portion of the air introduced through the air inlet (14) to the outside of the main body (10) through the air outlet (15). The second flow path (P2) can extend from the inlet space (201) through the air outlet (15) toward the outside of the main body (10).

[0178] The blower (20) can form a third flow path (P3) by introducing another portion of the air introduced through the air inlet (14) into the second body (300) through the body opening (210, 310) and discharging it to the outside of the main body (10) through the humid air outlet (17). The third flow path (P3) can extend from the inlet space (201) toward the outside of the main body (10) by sequentially passing through the body opening (210, 310) and the humid air outlet (17).

[0179] As the first air passage (P1), the second air passage (P2), and the third air passage (P3) are formed inside the air conditioner (1), some of the air introduced through the air inlet (14) can be discharged through the air outlet (15), and other parts can be discharged through the humid air outlet (17). However, the method of air discharge of the air conditioner (1) is not limited to this. For example, all of the air introduced through the air inlet (14) may be discharged only through the air outlet (15). Also, all of the air introduced through the air inlet (14) may be discharged only through the humid air outlet (17).

[0180] According to the concept of the present disclosure, the humidification device (70) may include a first sensor (S1) provided to detect the weight of the water tank (71).

[0215] A pattern portion (113) may be provided on the incident surface (111) and the exit surface (112) of the interaction ring (110). The pattern portion (113) may be formed by at least one method among etching, printing, screen printing, and stamping.

The thickness, shape, density, etc., of the pattern portion (113) of the interaction ring (110) can be varied.

[0216] The interaction ring (110) is made of a transparent material and is mounted on a light guide member (120) described later, so that light is scattered from the final emission surface (112) to express mood lighting.

[0217] The LED module (100) may include an LED light source (101) and a light guide member (120) provided to guide light irradiated from the LED light source (101).

A plurality of LEDs (102) may be spaced apart from each other on the printed circuit board (103). A plurality of LEDs (102) may be mounted on a single printed circuit board (103) to form an LED PBA.

[0219] According to the concept of the present disclosure, the LED light source (101) can be arranged so that LEDs (102) are arranged at equal intervals for circular decorative lighting. For example, a rectangular printed circuit board (103) can be arranged at a second angle (θ2). That is, five LEDs (102) can be placed on the rectangular printed circuit board (103) and arranged in a regular octagonal shape. In this embodiment, one printed circuit board (103) on which five LEDs (102) are placed for circular decorative lighting forms an LED PBA, and the LED PBA is arranged in a regular octagonal shape and five LEDs (102) are arranged at equal intervals, as illustrated as an example, but is not limited thereto.

[0220] The LED module (100) may include an LED frame (130) provided for installing an LED light source (101). The LED frame (130) may include a light source installation section (131) for installing the LED light source (101). The light source installation section (131) of the LED frame (130) may be provided with a light source installation opening (131a) for installing a plurality of LEDs (102). The light source installation opening (131a) may be spaced apart from the light source installation section (131) at a certain interval. The light source installation opening (131a) may be provided so that an LED PBA is seated thereon and light is emitted upward.

[0221] The light source installation part (131) of the LED frame (130) may be provided in a regular octagonal shape so that the LED module (100) can implement circular decorative lighting. This embodiment is illustrated as an example in which five LEDs (102) are arranged on a printed circuit board (103), but is not limited thereto.

[0222] The LED module (100) is positioned between the interaction ring (110) and the LED light source (101) and may include a light guide member (120) that guides the light from the LED light source (101) to spread naturally so that the light is uniformly focused on the interaction ring (110).

[0223] A light guide member (120) according to the concept of the present disclosure may be provided to uniformly scatter light generated from an LED light source (101) and transmit it to the upper exit surface (112) of an interaction ring (110).

[0224] The light guide member (120) may include a first part (121) and a second part (122) extending from the first part (121). The first part (121) is provided on the upper part of the light guide member (120) and is provided so that the interaction ring (110) can be supported. The second part (122) may be provided extending downward from the first part (121). The second part (122) may be formed by extending from one side and the other side of the first part (121). The second part (122) may include an inner part (122a) of the second part formed by extending from the inner side of the first part (121). The second part (122) may include an outer part (122b) of the second part formed by extending from the outer side of the first part (121). The inner side (122a) and the outer side (122b) of the second part (122) may be spaced apart. The inner side (122a) and the outer side (122b) of the second part (122) may form a space (120a) within them. An LED light source (101) may be positioned in the space (120a) of the light guide member (120).

[0225] According to the concept of the present invention, the distance (l) between the first part (121) of the light guide member (120) and the LED light source (101) can be positioned such that the brightness uniformity of the emission surface (112) of the interaction ring (110) is 70% or higher. For example, as the distance (l) between the LED light source (101) located below the space portion (120a) of the light guide member (120) and the first part (121) of the light guide member (120) increases, the uniformity increases, but the brightness may decrease. Therefore, when the brightness uniformity of the emission surface (112) of the interaction ring (110) approaches 70%, the distance (l) between the first part (121) of the light guide member (120) and the LED light source (101) can be set.

[0226] The light guide member (120) can be provided so that light emitted from an LED light source (101) placed below the space portion (120a) can naturally spread upward. The light guide member (120) can be placed on the light guide member installation portion (132) of the LED frame (130). The light guide member installation portion (132) of the LED frame (130) can be located above the light source installation portion (131). That is, by providing the light guide member (120) above the light source installation portion (131) of the LED frame (130), light emitted upward through the light source installation opening (131a) of the light source installation portion (131) can naturally spread upward.

[0227] The LED light source (101) may include a plurality of LEDs (102). The plurality of LEDs (102) may include a plurality of light-emitting diodes that emit light of at least one or two or more colors.

[0228] A plurality of light-emitting diodes are provided to emit light of different colors. For example, different colors may include red (R), yellow (Y), green (G), white (W), and blue (B), etc. The plurality of light-emitting diodes may include RGB LEDs capable of changing colors.

[0229] FIG. 14 is a control block diagram of a humidifying air purifier according to one embodiment. FIG. 15 is an example diagram of an interaction ring display by a first sensor according to one embodiment. FIG. 16 is an example diagram of an interaction ring display by a second sensor according to one embodiment.

[0230] Referring to FIGS. 14 to 16, the humidifying air purifier (1) may include a first sensor (S1), a second sensor (S2), and a control unit (90). Additionally, the humidifying air purifier (1) may include a user interface (80) and a memory (91).

[0231] The memory (91) can store programs and data for controlling the operation of the humidifying air purifier (1). The control unit (90) is electrically connected to various components of the humidifying air purifier (1) and can control each of them.

[0232] A first sensor (S1) may be provided to detect the weight of the water container (71). Multiple first sensors (S1) may be provided. A second sensor (S2) may be provided to detect the temperature of the water in the water container (71). A second sensor (S2) may be provided to detect the temperature of the water stored inside the water container (71).

[0233] The control unit (90) can control the LED module (100) described later so that information of the humidifying air purifier (1) is visualized through the interaction ring (110) based on at least one of the first sensor (S1) and the second sensor (S2).

[0234] The first sensor (S1) can detect the weight of the water container (71). The first sensor (S1) detects the weight of the water container (71), and when the water in the water container (71) is low, the control unit (90) can control the interaction ring (110) to blink on / off.

[0235] For example, the first sensor (S1) can detect that the water in the water tank (71) is insufficient, and the user can intuitively confirm that the water is insufficient by the motion of the interaction ring (110) repeatedly blinking on and off without having to check the water level of the internal water tank (71). For example, when the water in the water tank (71) is insufficient, the color of the interaction ring (110) is blue (B), and this can be indicated by repeated on / off blinking.

[0236] That is, when the water in the water tank (71) is low, the user can intuitively confirm that there is a water shortage by the blinking motion of the blue (B) lighting of the interaction ring (110) without having to check the water level of the internal water tank (71).

[0237] For example, the control unit (90) can detect the water level inside the water tank (71) by the first sensor (S1) and display it on the interaction ring (110). Specifically, blue (B) colored lighting rises clockwise on the circular interaction ring (110), allowing one to check how much the current water level has risen. That is, based on the circle, the water tank (71) is filled with water when it is full, which is 100%, and the weight of the internal water tank (71) can be detected and displayed as lighting on the interaction ring (110).

[0238] For example, when refilling the water in the water tank (71), the first sensor (S1) allows for an intuitive determination of how much water has been refilled even if the inside of the water tank (71) is not visible, thereby preventing water overflow. Specifically, blue (B) colored lighting rises clockwise on the circular interaction ring (110), allowing for an intuitive determination of how much water has been refilled.

[0239] The second sensor (S2) can detect the temperature of the water. The second sensor (S2) detects the temperature of the water inside the water tank (71), and the control unit (90) can display it on the interaction ring (110).

[0240] For example, the humidifying air purifier (1) according to the concept of the present invention requires a preparation time for boiling water due to the characteristics of the heated humidification device (70). The second sensor (S2) detects the temperature of the water to determine how much the water has boiled and can display the remaining time until the humidification device (70) operates through lighting via the interaction ring (110). The remaining time until the humidification device (70) operates can be displayed by white (W) color lighting of the interaction ring (110).

[0241] For example, when the humidifier (70) intends to detach a hot water tank (71) of 40°C or higher for safety reasons, the temperature of the water can be detected by the second sensor (S2) and displayed as a red (R) colored light through the interaction ring (110). That is, the user can be given a warning through the red (R) colored interaction ring (110). Specifically, the temperature of the water can be detected by the second sensor (S2), and the red (R) color of the interaction ring (110) can fill up clockwise to indicate the remaining time when the water tank (71) can be detached.

[0242] For example, when cleaning the humidification device (70) of the humidifying air purifier (1), the inside of the water tank (71) is cleaned by boiling water diluted with citric acid, etc. When cleaning the water tank (71) of the humidification device (70), the second sensor (S2) can detect the temperature of the water and display it as a light through the interaction ring (110). The interaction ring (110) can display a red (R) color light. That is, based on the circle, the temperature of the internal water can be detected and displayed as a red (R) light on the interaction ring (110), with the water in the water tank (71) being fully heated as 100%.
