[0174] The recess (311b) of the first tank (311) can be provided in correspondence with the induction heating coil (240).

[0175] The lower surface of the first tank (311) of the water tank (310) may be the lower surface of the second tank (312) of the water tank (310). The lower surface of the first tank (311) of the water tank (310) may be the lower surface of the water tank (310).

[0176] The second tank (312) can be formed in the shape of a triangular flask overall.

[0177] The second tank (312) may include a seating member (312a) provided adjacent to the protrusion (311a), an inclined member (312b) connected to the seating member (312a), and a vertical member (312c) connected to the inclined member (312b).

[0178] The seating member (312a) of the second tank (312) may be provided along the protrusion (311a). The seating member (312a) of the second tank (312) may be provided to surround the recess (311b) of the first tank (311). The seating member (312a) of the second tank (312) may be provided to accommodate the recess (311b) of the first tank (311).

[0179] The mounting member (312a) of the second tank (312) can be provided at a position corresponding to the heating source (240) and can be provided to correspond to the shape of the heating source (240).

[0180] When the heating source (240) is circular, the diameter of the seating member (312a) of the second water tank (312) may be formed to be the same as the diameter of the heating source (240) or larger than the diameter of the heating source (240).

[0181] The fluid in the heating area (S1) inside the mounting member (312a) of the second tank (312) and the fluid in the storage area (S2) outside the mounting member (312a) of the second tank (312) can be partitioned so as not to mix freely with each other. Here, the storage area outside the mounting member (312a) of the second tank (312) may be the storage area of ​​the first tank (311).

[0182] However, the heating area (S1) inside the seating member (312a) of the second water tank (312) and the storage area (S2) outside the seating member (312a) of the second water tank (312) are not completely sealed off from each other, and water may flow from the outside of the seating member (312a) of the second water tank (312) into the inside of the seating member (312a) of the second water tank (312) through the flow hole existing between the bottom surface of the water tank (310) and the seating member (312a) when the water level inside the seating member (312a) of the second water tank (312) is lower than the water level outside the seating member (312a) of the second water tank (312) due to the difference in water pressure.

[0183] The inclined member (312b) of the second tank (312) may be provided at an angle to the seating member (312a). The inclined member (312b) of the second tank (312) may be provided at an angle toward the center of the second tank (312). The inclined member (312b) of the second tank (312) may be provided such that the internal cross-sectional area decreases from the bottom to the top of the second tank. The inclined member (312b) of the second tank (312) may form a reference angle with respect to the vertical direction. For example, the reference angle may include an angle greater than 45°.

[0184] The inclined member (312b) of the second tank (312) can be provided to cover a heating area (S1) that is heated by a heating source (240) in the recessed portion (311b) of the first tank (311). Accordingly, the amount of heat generated by the heating source (240) can be concentratedly transferred to the inner space of the inclined member (312b) of the second tank (312), so that steam can be generated within a short time from the initial operation of the heating source (240).

[0185] Since the volume of water contained in the inclined member (312b) of the second water tank (312) becomes very small, rapid humidification is possible in which the time required for the water to start heating and for steam to be generated is greatly reduced.

[0186] By allowing heat generation to occur over a wide area of ​​the lower surface of the second tank of the water tank (310) according to the size of the heating source (240), the heat density, which is the amount of heat generated per unit area, can be reduced. Accordingly, when the heating source (240) heats the lower surface of the second tank of the water tank (310) for humidification, the noise generated during the water heating process can be reduced due to the low heat density.

[0187] The vertical member (312c) of the second tank (312) can be provided vertically in the vertical direction from the inclined member (312b) of the second tank (312).

[0188] The vertical member (312c) of the second tank (312) may be an area where steam is generated as the water is heated.

[0189] The vertical member (312c) of the second tank (312) can guide the generated steam to be discharged to the outside. The vertical member (312c) of the second tank (312) can have a height higher than the maximum water level of the first tank of the water tank (110).

[0190] The vertical member (312c) of the second tank (312) can be formed in a long cylindrical shape.

[0191] When the heating source (240) is circular, the diameter (L) of the vertical member (312c) of the second water tank (312) may be formed to be equal to or smaller than the diameter of the heating source (240).

[0192] The vertical member (312c) of the second tank (312) may include a cylindrical side parallel to the vertical direction. In this case, the angle formed between the inner surface of the vertical member (312c) of the second tank (312) and the vertical direction may be 0°.

[0193] If the diameter (L) of the vertical member (312c) of the second tank (312) is small, the volume of the vertical member (312c) can be reduced. Accordingly, the time required for steam to be generated from the initial operation of the heating source (240) can be reduced.

[0194] As illustrated in FIG. 6, the housing (200) may include a first case (210), a second case (220), and a frame (230).

[0195] The first case (210) may be provided in the main body (10). The first case (210) may be provided in the receiving space 10a of the main body (10).

[0198] The first cover (370) of the water tank assembly (300) can be mounted on the first case (210).

[0199] When the water tank assembly (300) is accommodated in the receiving space 10a, the first case (210) can be provided spaced apart from the water tank case (320) of the water tank assembly (300) by the first cover (370) of the water tank assembly (300).

[0200] The second case (220) may be provided in the main body (10). The second case (220) may be provided in the receiving space 10a of the main body (10). The second case (220) may be provided in the lower part of the main body (10). The second case (220) may be provided so as to be detachable from the main body (10).

[0201] The second case (220) may be provided on the lower side of the housing (200). The second case (220) may be provided on the lower side of the first outer case (210).

[0202] The second case (220) can accommodate the water tank assembly (300). The second case (220) can be adjacent to the lower part of the water tank case (320) of the water tank assembly (300).

[0203] The second case (220) may be formed of a material having relatively high magnetic field transmittance and heat resistance. For example, the second case (220) may be formed of a material such as heat-resistant glass, ceramic, or heat-resistant plastic.

[0204] The first and second cases (210, 220) can be separated from the housing (200) together with the water tank assembly (300). The first and second cases (210, 220) can also be accommodated within the housing (200) together with the water tank assembly (300).

[0205] The frame (230) can be provided inside the main body (10) and can be provided on the lower side of the first panel (11).

[0206] The frame (230) is provided inside the housing (200), but can be provided corresponding to the edge of the housing (200).

[0207] The frame (230) can support the first case (210). The upper side of the first case (210) can be mounted on the frame (230).

[0208] The frame (230) may be provided with the same shape as the upper side of the first case (210). The frame (230) may be provided in a ring shape.

[0209] As shown in FIG. 7, the frame (230) may be provided with one or more weight sensors (150: R1, R2, R3, R4). A humidifier equipped with four weight sensors will be described below.

[0210] A plurality of weight sensors (150) may be provided on the lower side of the frame (230) and spaced apart at regular intervals.

[0211] A plurality of weight sensors (150) may be provided in a ring-shaped frame (230) and may be provided facing the inside of the frame (230).

[0212] A first case (210) can be contacted and mounted on a plurality of weight sensors (150).

[0213] As illustrated in FIG. 8, a protruding member (211) that protrudes from the outside of the first case (210) and protrudes downward from the first case (210) may be in contact with each of the plurality of weight sensors (150). That is, when the first case (210) is mounted on the plurality of weight sensors (150), the protruding member (211) of the first case (210) may be in contact with each of the plurality of weight sensors (150).

[0214] A plurality of weight sensors (150) can detect the weight of the first case (210) mounted on the plurality of weight sensors (150) provided on the frame (230).

[0215] Since the water tank assembly (300) is mounted on the first case (210), the weight detected by the plurality of weight sensors (150) may be the sum of the weight of the first case (210) and the water tank assembly (300).

[0216] When water is stored in the water tank (310) of the water tank assembly (300), the weight detected by the plurality of weight sensors (150) may be the sum of the weight of the first case (210), the weight of the water tank assembly (300), and the weight of the water.

[0217] The weight detected by a plurality of weight sensors (150) can be used to detect the weight of water stored in the water tank (310). Here, the weight of the water may include the amount of water.

[0218] The accuracy of detecting the amount of water can be improved by using multiple weight sensors (150) to detect the amount of water stored in the water tank (310).

[0219] Referring to FIG. 9, a method of detecting weight using a plurality of weight sensors (150) is described.

[0220] Under no-load condition, the weight detected by multiple weight sensors is as follows.

[0221] For example, the no-load may be a water tank assembly in which no water is stored within the water tank and a first case. The weight detected during the no-load may be the sum of the weight of the first case and the weight of the water tank assembly.

[0222] V AB =(R1 / (R1+R2))×V, V AD =(R4 / (R3+R4))×V,

[0223] E=V AB - V AD=((R1R3-R2R4) / (R1+R2)(R3+R4))×V

[0224] Under load, the weight detected by multiple weight sensors is as follows.

[0225] The load may be water stored in the water tank of the water tank assembly. The weight detected at load may include the weight of the water stored in the water tank.

[0226] △E= (S1 / S2)×V

[0227] S1=(R1+△R1)×(R3+△R3) -(R2+△R2)×(R4+△R4)

[0228] S2= (R1+△R1+R2+△R2)×(R3+△R3+R4+△R4)

[0229] Weight = E - △E

[0404] The target temperature is the temperature that the temperature sensor (160) must reach, which is the temperature that the actual temperature of the water stored in the second tank is to be detected at the time when the temperature sensor reaches a preset temperature. The target temperature may be the temperature for recognizing the completion of the first preheating mode.

[0405] The humidifier (1) can perform a first preheating mode among the preheating modes included in the quick humidification mode (305). Performing the first preheating mode may include controlling the output of the heating source (240) to a first output.

[0406] The humidifier (1) can recognize whether the temperature detected by the temperature sensor (160) has reached the target temperature based on the temperature information detected by the temperature sensor (160) during the performance of the first preheating mode (306).

[0407] When the temperature detected by the temperature sensor (160) is recognized as having reached the target temperature, the humidifier (1) can complete the first preheating mode and perform the second preheating mode (307).

[0408] Performing the second preheating mode may include controlling the output of the heating source (240) to a second output. Here, the second output may be a lower output than the first output. For example, the first output may be 1500W and the second output may be 600W, but the values ​​of the first and second outputs are not limited thereto.

[0409] The humidifier (1) counts the execution time of the second preheating mode while performing the second preheating mode and can recognize whether the counted execution time of the second preheating mode has reached a preset reference operation time (308).

[0410] The humidifier (1) can complete the second preheating mode and perform the normal humidification mode (309) based on the recognition that the counted execution time of the second preheating mode has reached a preset reference operation time.

[0411] Performing a general humidification mode may include recognizing a general humidification mode selected by a user, controlling the output of a heating source (240) based on the recognized general humidification mode, and controlling the rotational speed of a blower (20).

[0412] Controlling the output of the heating source (240) may include controlling the value of the output of the heating source (240).

[0413] For example, based on the fact that the general humidification mode selected by the user is the Power High mode, the output of the heating source can be controlled to a third output, and the rotational speed of the blower can be controlled to a first rotational speed. Here, the third output may include an output value between the first output and the second output.

[0414] As another example, based on the fact that the general humidification mode selected by the user is the medium power mode, the output of the heating source can be controlled to a fourth output, and the rotational speed of the blower can be controlled to a second rotational speed. Here, the fourth output may include an output value smaller than the third output. Here, the fourth output may include an output value smaller than the second output.

[0415] The second rotation speed can be slower than the first rotation speed.

[0419] FIG. 20 is a table showing information on the target operating time matched by the initial temperature range of the temperature sensor of the humidifier according to various embodiments and the weight of the water.

[0420] The mechanical configuration of the humidifier (2) of various embodiments may be identical or similar to the mechanical configuration of the humidifier (1) of one embodiment shown in FIGS. 1 to 11. Accordingly, the description of the mechanical configuration of the humidifier (2) is omitted.

[0421] One example humidifier (2) may include a blower (20), a heating source (240), a user interface (e.g., including an electrical network) (100), a weight sensor (150), a temperature sensor (160), and a second control unit (e.g., including an electrical network) (180).

[0422] The blower (20), heating source (240), user interface (100), weight sensor (150), and temperature sensor (160) of the humidifier (2) are identical or similar to the blower (20), heating source (240), user interface (100), weight sensor (150), and temperature sensor (160) of the humidifier (1), so the description is omitted.

[0423] To distinguish it from the first control unit, the control unit of the humidifier (2) is described as the second control unit (180). Regarding the configuration of the second control unit of the humidifier of another embodiment that is identical to the configuration of the first control unit of the humidifier of one embodiment, the description is omitted.

[0424] The second control unit (180) includes various processing electrical circuit networks and can control the quick humidification mode based on temperature information detected by a temperature sensor and weight information detected by a weight sensor before controlling the performance of the general humidification mode.

[0425] The second control unit (180) can control the execution of the first and second preheating modes based on the initial temperature detected by the temperature sensor being below the reference temperature, and control the execution of the second preheating mode based on the initial temperature detected by the temperature sensor being above the reference temperature. Here, the reference temperature may be approximately 50°C. This will be explained in more detail.

[0426] The second control unit (180) can recognize temperature information detected by the temperature sensor (160) when the start time of humidification operation is recognized, and can recognize the weight of water based on weight information detected by the weight sensor (150).

[0427] The temperature information detected by the temperature sensor (160) may include information about the initial temperature detected by the temperature sensor at the start of the humidification operation.

[0428] The second control unit (180) can compare the initial temperature detected by the temperature sensor (160) with the reference temperature. The second control unit (180) can recognize whether the initial temperature detected by the temperature sensor (160) is below the reference temperature. For example, the reference temperature may be approximately 50°C, but the reference temperature is not limited to this.

[0429] Below, the control configuration of the quick humidification mode of the second control unit when the initial temperature detected by the temperature sensor (160) is below the reference temperature is described.

[0430] If the initial temperature detected by the temperature sensor (160) is less than the reference temperature, the second control unit (180) can recognize a target temperature corresponding to the weight of the recognized water based on the information stored in the second memory (182).

[0431] If the initial temperature detected by the temperature sensor (160) is less than the reference temperature, the second control unit (180) may recognize the weight range of water to which the recognized weight of water belongs based on the information stored in the second memory (182) and recognize the target temperature corresponding to the recognized weight range of water.

[0432] As illustrated in FIG. 16, the second control unit (180) can recognize the weight range of water to which the recognized water weight of 3.7 kg belongs if the recognized water weight is 3.7 kg, and can recognize a target temperature of 146°C corresponding to the weight range of water to which the recognized water weight is 1.3 kg, and can recognize the weight range of water to which the recognized water weight of 1.3 kg belongs if the recognized water weight is 1.3 kg, and can recognize a target temperature of 126°C corresponding to the weight range of water to which the recognized water weight is 1.3 kg.

[0433] The target temperature may be the temperature detected by the temperature sensor when the actual temperature of the water in the second tank reaches a preset temperature. That is, the second control unit (180) must ensure that the temperature detected by the temperature sensor (160) reaches the target temperature in order to cause the water in the second tank to turn into steam.

[0434] The target temperature may be the temperature for recognizing the completion of the first preheating mode.

[0435] The second control unit (180) can control the execution of the first preheating mode of the quick humidification mode.

[0436] The second control unit (180) can control the output of the heating source (240) to the first output to control the execution of the first preheating mode.

[0437] The second control unit (180) can recognize whether the temperature detected by the temperature sensor (160) has reached the target temperature based on the temperature information detected by the temperature sensor (160) during the execution of the first preheating mode.

[0438] The second control unit (180) can complete the first preheating mode and control the execution of the general humidification mode when it recognizes that the temperature detected by the temperature sensor (160) has reached the target temperature. The second control unit (180) can control the transition from the first preheating mode to the general humidification mode.

[0439] The second control unit (180) may complete the first preheating mode and control the execution of the second preheating mode when it recognizes that the temperature detected by the temperature sensor (160) has reached the target temperature. The second control unit (180) may control the transition from the first preheating mode to the second preheating mode.

[0440] The second control unit (180) can control the output of the heating source (240) to a second output to control the execution of the second preheating mode. Here, the second output may be a lower output than the first output. For example, the first output may be 1500W and the second output may be 600W, but the values ​​of the first and second outputs are not limited thereto.

[0441] The second control unit (180) can control the execution of the second preheating mode during a preset reference operation time. For example, the second control unit (180) can count the execution time of the second preheating mode while the second preheating mode is being executed, and complete the second preheating mode and control the execution of the general humidification mode based on the counted execution time of the second preheating mode reaching the reference operation time. The second control unit (180) can control the transition from the second preheating mode to the general humidification mode.

[0442] The second control unit (180) can control the output of the heating source (240) and the rotational speed of the blower (20) based on a general humidification mode selected by the user.

[0443] Controlling the output of the heating source (240) may include controlling the value of the output of the heating source (240).

[0444] Below, the control configuration of the quick humidification mode of the second control unit when the initial temperature detected by the temperature sensor (160) is above the reference temperature is described.

[0445] If the initial temperature detected by the temperature sensor (160) is greater than or equal to the reference temperature, the second control unit (180) can recognize a target operating time corresponding to the weight of the water recognized based on the information stored in the second memory (182).

[0446] If the initial temperature detected by the temperature sensor (160) is greater than or equal to the reference temperature, the second control unit (180) may recognize the weight range of water to which the recognized weight of water belongs based on the information stored in the second memory (182) and recognize the target operating time corresponding to the recognized weight range of water.

[0447] As illustrated in FIG. 17, the second control unit (180) can recognize the weight range of water to which the recognized water weight of 3.7 kg belongs if the recognized water weight is 3.7 kg, and can recognize a target operating time of 180 seconds corresponding to the recognized water weight range, and can recognize the weight range of water to which the recognized water weight of 1.3 kg belongs if the recognized water weight is 1.3 kg, and can recognize a target operating time of 98 seconds corresponding to the recognized water weight range.

[0448] The target operating time may be the time required for the actual temperature of the water in the second tank to reach a preset temperature. That is, the second control unit (180) can control the heating time of the heating source to heat the water for a time corresponding to the weight of the water so that the water in the second tank is converted into steam.

[0449] The target driving time may be the time to recognize the completion of the second preheating mode.

[0450] The second control unit (180) can control the execution of the second preheating mode and not perform the first preheating mode of the quick humidification mode if the initial temperature detected by the temperature sensor (160) is above the reference temperature.

[0451] The second control unit (180) can control the output of the heating source (240) to the second output to control the execution of the second preheating mode.

[0452] The second control unit (180) can control the execution of the second preheating mode during the recognized target operating time. More specifically, the second control unit (180) counts the execution time of the second preheating mode during the execution of the second preheating mode, and completes the second preheating mode and controls the execution of the general humidification mode based on the counted execution time of the second preheating mode reaching the target operating time.

[0453] The second control unit (180) can control the output of the heating source (240) and the rotational speed of the blower (20) based on a general humidification mode selected by the user.

[0454] The second control unit (180) recognizes the rotational speed of the blower corresponding to the general humidification mode received through the input unit (111) based on information stored in the second memory (182), and it is also possible to control the rotational speed of the blower when controlling the quick humidification mode based on the recognized rotational speed of the blower. Here, the rotational speed of the blower may include the fan rotational speed.

[0455] For example, if the general humidification mode received through the input unit (111) is a power strong mode, the second control unit (180) recognizes a fan rotation speed of 1650 RPM corresponding to the power strong mode and can control the fan rotation speed to 1650 RPM while performing the first preheating mode and the second preheating mode, and if the general humidification mode received through the input unit (111) is a windless mode, it recognizes a fan rotation speed of 800 RPM corresponding to the windless mode and can control the fan rotation speed to 800 RPM while performing the first preheating mode and the second preheating mode.

[0456] The rotational speed of the fan in the first preheating mode and the rotational speed of the fan in the second preheating mode for each general humidification mode may be the same or different. For example, the rotational speed of the fan corresponding to the first preheating mode in the Power Strong mode may be the same or different from the rotational speed of the fan corresponding to the second preheating mode in the Power Strong mode.

[0457] The rotational speed of the fan in each general humidification mode when the initial temperature of the temperature sensor is below the reference temperature, and the rotational speed of the fan in each general humidification mode when the initial temperature of the temperature sensor is above the reference temperature, may be the same or different from each other.

[0458] For example, when the initial temperature of the temperature sensor is below the reference temperature, the rotational speed of the fan corresponding to the second preheating mode in the power strong mode may be the same as or different from the rotational speed of the fan corresponding to the second preheating mode in the power strong mode when the initial temperature of the temperature sensor is above the reference temperature.

[0459] As illustrated in FIG. 18, the second control unit (180) can, if the initial temperature of the temperature sensor is below the reference temperature, recognize the rotational speed of the blower in the first preheating mode and the rotational speed of the blower in the second preheating mode corresponding to the general humidification mode received through the input unit (111) based on information stored in the second memory (182), control the rotation of the blower based on the rotational speed of the blower recognized during the execution of the first preheating mode, and control the rotation of the blower based on the rotational speed of the blower recognized during the execution of the second preheating mode.

[0460] As illustrated in FIG. 19, the second control unit (180) can recognize the rotational speed of the blower corresponding to the general humidification mode received through the input unit (111) based on information stored in the second memory (182) when the initial temperature of the temperature sensor is above the reference temperature, and can control the rotation of the blower based on the rotational speed of the blower recognized during the execution of the second preheating mode.

[0461] If the initial temperature of the temperature sensor (160) is above the reference temperature, the second control unit (180) may recognize a target operating time corresponding to the initial temperature and the weight of the water based on the information stored in the second memory (182), and control the execution time of the second preheating mode based on the recognized target operating time.

[0462] The target operating time can be shortened as the initial temperature increases for the same weight of water.

[0463] As illustrated in FIG. 20, the second control unit (180) can recognize an initial temperature range to which the initial temperature belongs and a weight range to which the weight of the water belongs based on information stored in the second memory (182) when the initial temperature of the temperature sensor (160) is above a reference temperature, and can also recognize a target operating time corresponding to the recognized initial temperature range and the recognized weight range of the water and control the execution time of the second preheating mode based on the recognized target operating time.

[0464] For example, if the initial temperature of the temperature sensor (160) is 65°C and the weight of the water is 3.2 kg, the second control unit (180) recognizes the initial temperature range to which the initial temperature 65°C belongs and the weight range to which the weight of the water 3.2 kg belongs based on the information stored in the second memory (182), recognizes the target operating time of 119 seconds corresponding to the recognized initial temperature range and the recognized weight range of the water, and can control the second preheating mode during the recognized target operating time of 119 seconds.

[0465] The second control unit (180) may include at least one second processor (181) for controlling the operation of the humidifier (2) and at least one second memory (182) for storing a program and data for controlling the operation of the humidifier (2).

[0466] An example of the configuration of at least one second processor (181) and at least one second memory (182) may be the same or similar as an example of the configuration of at least one first processor (171) and at least one first memory (172). Therefore, a description of a specific example thereof is omitted.

[0467] The second memory (182) can store information about the first output corresponding to the first preheating mode and the second output corresponding to the second preheating mode.

[0468] The second memory (182) can store information about the target temperature of the temperature sensor by weight of the water.

[0469] As illustrated in FIG. 16, the second memory (182) can also store information about the target temperature of the temperature sensor for each weight range of water.

[0470] The target temperature may be a temperature for determining the completion of the first preheating mode when the first preheating mode is performed while the initial temperature of the temperature sensor is below the reference temperature.

[0471] The target temperature may be a temperature that can be detected by the temperature sensor at the time when the temperature of the water in the second tank reaches a preset temperature when the quick humidification mode is performed while the initial temperature of the temperature sensor is below the reference temperature.

[0472] The second memory (182) can store information about the standard operating time.

[0473] The reference operating time may be the time required to recognize the completion of the second preheating mode when the second preheating mode is performed while the initial temperature of the temperature sensor is below the reference temperature. For example, the reference operating time may be approximately 12 seconds, but the reference operating time is not limited to this.

[0474] The second memory (182) can store information about the target driving time for each weight of water.

[0475] As illustrated in FIG. 17, the second memory (182) can also store information about the target driving time for each weight range of water.

[0476] The target operating time may be the time for determining the completion of the second preheating mode when the second preheating mode is performed while the initial temperature of the temperature sensor is above the reference temperature.

[0477] As illustrated in FIG. 18, the second memory (182) can store control information for each control target of the quick humidification mode corresponding to a standard humidification mode below a reference temperature.

[0478] As illustrated in FIG. 19, the second memory (182) can store control information for each control target of the quick humidification mode for each general humidification mode corresponding to a reference temperature or higher.

[0479] As illustrated in FIG. 20, the second memory (182) can store information corresponding to the target operating time matched by the initial temperature and the weight of the water, corresponding to a reference temperature or higher.

[0480] The second memory (182) can store information about a reference temperature. The reference temperature may be information for determining whether to perform the first preheating mode and the time to perform the second preheating mode.

[0481] At least one component may be added or removed in response to the performance of the components of the humidifier (2) illustrated in FIG. 15. Additionally, it will be readily understood by those skilled in the art that the relative positions of the components may be changed in response to the performance or structure of the humidifier (2).

[0482] Each component illustrated in FIG. 15 includes software and / or hardware components such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0483] FIG. 21 is a flowchart of the operation sequence of a humidifier according to various embodiments.

[0484] The humidifier (2) can recognize whether the current time is the start time of humidification operation (311).

[0485] When the humidifier (2) is recognized as the start time of humidification operation, it can recognize temperature information detected by the temperature sensor (160). The temperature information detected by the temperature sensor (160) may include information about the initial temperature detected by the temperature sensor at the start time of humidification operation. That is, when the humidifier (2) is recognized as the start time of humidification operation, it can recognize the initial temperature detected by the temperature sensor (160) (312).

[0486] The humidifier (2) can recognize the weight of the water based on weight information detected by the weight sensor (150) (313).

[0487] The humidifier (2) can recognize whether the initial temperature detected by the temperature sensor (160) is lower than the reference temperature by comparing the initial temperature detected by the temperature sensor (160) with the reference temperature (314).

[0488] If the initial temperature detected by the temperature sensor (160) is below the reference temperature, the humidifier (2) can recognize a target temperature corresponding to the weight of the water recognized based on the information stored in the second memory (182) (315).

[0489] If the initial temperature detected by the temperature sensor (160) is less than the reference temperature, the humidifier (2) may recognize the weight range of water to which the recognized weight of water belongs based on the information stored in the second memory (182) and recognize the target temperature corresponding to the recognized weight range of water.

[0490] The target temperature may be the temperature detected by the temperature sensor when the actual temperature of the water in the second tank reaches a preset temperature. The target temperature may be the temperature for recognizing the completion of the first preheating mode.

[0491] The humidifier (2) can perform the first preheating mode of the quick humidification mode (316).

[0492] Performing the first preheating mode may include controlling the output of the heating source (240) to the first output.

[0493] Performing the first preheating mode can also involve recognizing the rotational speed of the blower corresponding to the first preheating mode and controlling the blower based on the recognized rotational speed of the blower.

[0494] The humidifier (2) can recognize whether the temperature detected by the temperature sensor (160) has reached the target temperature based on the temperature information detected by the temperature sensor (160) during the performance of the first preheating mode (317).

[0496] Performing the second preheating mode may include controlling the output of the heating source (240) to a second output. Here, the second output may be an output lower than the first output.

[0497] Performing the second preheating mode can also involve recognizing the rotational speed of the blower corresponding to the second preheating mode and controlling the blower based on the recognized rotational speed of the blower.

[0498] The humidifier (2) can control the execution of the second preheating mode during a preset reference operation time. For example, the humidifier (2) can count the execution time of the second preheating mode while the second preheating mode is being executed and recognize whether the counted execution time of the second preheating mode has reached the reference operation time (319).

[0499] The humidifier (2) can complete the second preheating mode and perform the normal humidification mode (320) based on the recognition that the counted execution time of the second preheating mode has reached the reference operation time.

[0500] Performing a general humidification mode may include controlling the output of the heating source (240) and controlling the rotational speed of the blower (20) based on the general humidification mode selected by the user.

[0501] If the initial temperature detected by the temperature sensor (160) is above the reference temperature, the humidifier (2) can recognize a target operating time corresponding to the weight of the water recognized based on the information stored in the second memory (182) (321).

[0502] If the initial temperature detected by the temperature sensor (160) is above the reference temperature, the humidifier (2) can recognize the weight range of water to which the recognized weight of water belongs based on the information stored in the second memory (182) and recognize the target operating time corresponding to the recognized weight range of water.

[0503] The target operating time may be the time required for the actual temperature of the water in the second tank to reach a preset temperature. The target operating time may be the time required to recognize the completion of the second preheating mode.

[0504] If the initial temperature detected by the temperature sensor (160) is higher than the reference temperature, the humidifier (2) may not perform the first preheating mode of the quick humidification mode and may perform the second preheating mode (322).

[0505] Performing the second preheating mode may include controlling the output of the heating source (240) to the second output.

[0506] Performing the second preheating mode can also involve recognizing the rotational speed of the blower corresponding to the second preheating mode and controlling the blower based on the recognized rotational speed of the blower.

[0507] The humidifier (2) can control the performance of the second preheating mode during the recognized target operating time.

[0508] For example, the humidifier (2) can count the execution time of the second preheating mode while performing the second preheating mode and recognize whether the counted execution time of the second preheating mode has reached the target operation time (323).

[0509] The humidifier (2) can complete the second preheating mode and perform the normal humidification mode (320) based on the recognition that the execution time of the second preheating mode has reached the target operation time.

[0510] The humidifier (2) can control the output of the heating source (240) and the rotational speed of the blower (20) based on a general humidification mode selected by the user.

[0511] FIG. 22 is a control configuration diagram of a humidifier according to various embodiments, which will be explained with reference to FIG. 23.

[0513] The mechanical configuration of the humidifier (3) may be identical or similar to the mechanical configuration of the humidifier (1) shown in FIGS. 1 to 11. Accordingly, the description of the mechanical configuration of the humidifier (3) is omitted.

[0514] The humidifier (3) may include a blower (20), a heating source (240), a user interface (e.g., including an electrical network) (100), a weight sensor (150), a temperature sensor (160), and a third control unit (e.g., including an electrical network) (190).

[0515] The blower (20), heating source (240), user interface (100), weight sensor (150), and temperature sensor (160) of the humidifier (3) are identical or similar to the blower (20), heating source (240), user interface (100), weight sensor (150), and temperature sensor (160) of the humidifier (1), so the description is omitted.

[0516] To distinguish it from the first control unit and the second control unit, the control unit of the humidifier (3) is described as the third control unit. The description of the configuration of the third control unit of the humidifier that is identical or similar to the configuration of the first control unit and the second control unit of the humidifier is omitted.

Here, the reference temperature may be approximately 85°C. This will be explained in more detail.

[0519] The third control unit (190) can control the quick humidification mode based on temperature information detected by the temperature sensor (160) and weight information detected by the weight sensor (150) before controlling the execution of the general humidification mode.

[0524] If the initial temperature detected by the temperature sensor (160) is less than the reference temperature, the third control unit (190) recognizes the weight range of water to which the recognized weight of water belongs based on the information stored in the third memory (192), recognizes the initial temperature range corresponding to the recognized initial temperature, and it is also possible to recognize the target operating time corresponding to the recognized weight range of water and the initial temperature range.

[0525] As illustrated in FIG. 23, the third control unit (190) can recognize the weight range of water to which the recognized weight of water 3.7 kg belongs and the initial temperature to which the recognized initial temperature 55°C belongs when the recognized weight of water is 3.7 kg and the recognized initial temperature is 55°C, and can recognize a target operating time of 70 seconds corresponding to the weight range of water and the recognized initial temperature range.

[0526] The target operating time may be the time required for the actual temperature of the water in the second tank to reach a preset temperature while the output of the heating source is at the first output.

[0531] The third control unit (190) can complete the first preheating mode and control the execution of the general humidification mode when it recognizes that the execution time of the first preheating mode has reached the target operation time. The third control unit (190) can control the transition from the first preheating mode to the general humidification mode.

[0532] The third control unit (190) may also control the execution of the second preheating mode if the initial temperature detected by the temperature sensor (160) is greater than or equal to the reference temperature.

[0533] The third control unit (190) can control the output of the heating source (240) to a second output to control the execution of the second preheating mode. Here, the second output may be a lower output than the first output.

[0534] The third control unit (190) can control the execution of the second preheating mode during a preset reference operating time. The preset reference operating time may be approximately 10 seconds, but the reference operating time is not limited to this.

[0535] For example, the third control unit (190) can count the execution time of the second preheating mode while the second preheating mode is being executed, complete the second preheating mode based on the counted execution time of the second preheating mode reaching the reference operation time, and control the execution of the general humidification mode. The third control unit (190) can control the transition from the second preheating mode to the general humidification mode.

[0536] The third control unit (190) can control the output of the heating source (240) and the rotational speed of the blower (20) based on the general humidification mode selected by the user.

[0537] The third control unit (190) may include at least one third processor (191) for controlling the operation of the humidifier (3) and at least one third memory (192) for storing a program and data for controlling the operation of the humidifier (3).

Therefore, a description of a specific example thereof is omitted.

[0540] The third memory (192) can store information about the target operating time matched by the initial temperature range of the temperature sensor and the weight range of the water.

[0541] The target driving time may be the execution time of the first preheating mode.

[0542] The third memory (192) can store information about the standard operating time.

[0543] The reference driving time may be the execution time of the second preheating mode. For example, the reference driving time may be approximately 10 seconds, but the reference driving time is not limited to this.

[0544] At least one component may be added or removed in response to the performance of the components of the humidifier (3) shown in FIG. 22. Additionally, it will be readily understood by those skilled in the art that the relative positions of the components may be changed in response to the performance or structure of the humidifier (3).

[0545] Each component illustrated in FIG. 22 includes software and / or hardware components such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0546] FIG. 24 is a flowchart of the operation sequence of a humidifier according to various embodiments.

[0547] The humidifier (3) can recognize whether the current time is the start time of humidification operation (331).

[0548] When the humidifier (3) is recognized as the start time of humidification operation, it can recognize temperature information detected by the temperature sensor (160). The temperature information detected by the temperature sensor (160) may include information about the initial temperature detected by the temperature sensor at the start time of humidification operation. For example, when the humidifier (3) is recognized as the start time of humidification operation, it can recognize the initial temperature detected by the temperature sensor (160) (332).

[0549] The humidifier (3) can recognize the weight of the water based on weight information detected by the weight sensor (150) (333).

[0550] The humidifier (3) can recognize whether the initial temperature detected by the temperature sensor (160) is below the reference temperature by comparing the initial temperature detected by the temperature sensor (160) with the reference temperature (334). The reference temperature is approximately 85°C, but the reference temperature is not limited to this.

[0551] If the initial temperature detected by the temperature sensor (160) is below the reference temperature, the humidifier (3) can recognize the weight of the water and the target operating time corresponding to the recognized initial temperature based on the information stored in the third memory (192) (335).

[0552] If the initial temperature detected by the temperature sensor (160) is less than the reference temperature, the humidifier (3) recognizes the weight range of water to which the recognized weight of water belongs based on the information stored in the third memory (192), recognizes the initial temperature range corresponding to the recognized initial temperature, and also recognizes the target operating time corresponding to the recognized weight range of water and the initial temperature range.

[0553] The humidifier (3) can perform the first preheating mode of the quick humidification mode (336).

[0554] Performing the first preheating mode may include controlling the output of the heating source (240) to the first output.

[0555] Performing the first preheating mode may include recognizing the rotational speed of a blower corresponding to a general humidification mode received through an input unit, and controlling the blower based on the recognized rotational speed.

[0556] The rotation speed of the blower in each general humidification mode may be faster in modes with higher humidification capacities.

[0557] The humidifier (3) can count the execution time of the first preheating mode while performing the first preheating mode and recognize whether the counted execution time of the first preheating mode has reached the target operation time (337).

[0558] When the humidifier (3) recognizes that the execution time of the first preheating mode has reached the target operation time, it can complete the first preheating mode and perform the normal humidification mode (338).

[0559] The humidifier (3) can perform a second preheating mode (339) if the initial temperature detected by the temperature sensor (160) is above the reference temperature.

[0560] Performing the second preheating mode may include controlling the output of the heating source (240) to a second output. Here, the second output may be an output lower than the first output.

[0561] The humidifier (3) can control the performance of the second preheating mode during the standard operating time. The preset standard operating time may be approximately 10 seconds, but the standard operating time is not limited to this.

[0562] For example, the humidifier (3) counts the execution time of the second preheating mode while performing the second preheating mode and can recognize whether the counted execution time of the second preheating mode has reached the reference operation time (340).

[0563] The humidifier (3) can complete the second preheating mode and perform the normal humidification mode based on the recognition that the counted execution time of the second preheating mode has reached the reference operation time (338).

[0564] The humidifier (3) can control the output of the heating source (240) and the rotational speed of the blower (20) based on a general humidification mode selected by the user.

[0565] For example, based on the fact that the general humidification mode of the humidifier (3) is a high power mode, the output of the heating source can be controlled to a third output, and the rotational speed of the blower can be controlled to a first rotational speed. The third output may be higher than the second output or equal to the second output.

[0566] Based on the fact that the general humidification mode of the humidifier (3) is a power medium mode, the output of the heating source can be controlled to a fourth output, and the rotational speed of the blower can be controlled to a second rotational speed. The fourth output may be lower than the third output. The second rotational speed may be slower than the first rotational speed.

[0567] Based on the fact that the general humidification mode of the humidifier (3) is a strong mode, the output of the heating source can be controlled to a fifth output, and the rotational speed of the blower can be controlled to a third rotational speed. The fifth output may be lower than the fourth output. The third rotational speed may be slower than the second rotational speed.

[0568] Based on the fact that the general humidification mode of the humidifier (3) is a weak mode, the output of the heating source can be controlled to a sixth output, and the rotational speed of the blower can be controlled to a fourth rotational speed. The sixth output may be lower than the fifth output. The fourth rotational speed may be slower than the third rotational speed.

[0569] Based on the fact that the general humidification mode of the humidifier (3) is a windless mode, the output of the heating source can be controlled to a 7th output, and the rotational speed of the blower can be controlled to a 5th rotational speed. The 7th output may be lower than the 6th output. The 5th rotational speed may be slower than the 4th rotational speed.

[0570] Based on the fact that the general humidification mode of the humidifier (3) is a sleep mode, the output of the heating source can be controlled to the 8th output, and the rotational speed of the blower can be controlled to the 6th rotational speed. The 8th output may be lower than the 7th output. The 6th rotational speed may be slower than the 5th rotational speed.

[0571] The rotational speed of the fan when performing the normal humidification mode may be the same or similar to the rotational speed of the fan when performing the quick humidification mode, or it may be slower than the rotational speed of the fan when performing the quick humidification mode.
