[0170] The protrusion (311a) of the first tank (311) can be seated in the water tank case (320).

[0171] The recess (311b) of the first tank (311) can be provided in correspondence with the induction heating coil (240).

[0172] 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).

[0173] The second tank (312) can be formed in the shape of a triangular flask overall.

[0174] 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).

[0175] 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).

[0176] 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).

[0177] 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 (130).

[0178] 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).

[0179] However, the heating area (S1) inside the mounting member (312a) of the second water tank (312) and the storage area (S2) outside the mounting 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 mounting member (312a) of the second water tank (312) into the inside of the mounting member (312a) of the second water tank (312) through the flow hole existing between the bottom surface of the water tank (310) and the mounting member (312a) when the water level inside the mounting member (312a) of the second water tank (312) is lower than the water level outside the mounting member (312a) of the second water tank (312) due to the difference in water pressure. In this way, the second water tank (312) can be provided connected to the first water tank (311) by a space.

[0180] 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°.

[0181] 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).

[0182] Since the volume of water contained in the inclined member (312b) of the second water tank (312) is 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.

[0183] 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.

[0184] 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).

[0185] The vertical member (312c) of the second tank (312) may be an area where steam is generated as the water is heated.

[0186] 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).

[0187] The vertical member (312c) of the second tank (312) can be formed in a long cylindrical shape.

[0188] 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 the diameter of the heating source (240) or smaller than the diameter of the heating source (130).

[0189] 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°.

[0190] 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.

[0191] As illustrated in FIG. 6, the housing (200) may include a first case (210), a second case (220), and a frame (230).

[0192] 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).

[0195] The first cover (370) of the water tank assembly (300) can be mounted on the first case (210).

[0196] When the water tank assembly (300) is accommodated in the receiving space (10a), the first case (210) can be 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).

[0197] 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).

[0198] 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).

[0199] 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).

[0200] 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.

[0201] 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).

[0202] The frame (230) can be provided inside the main body (10) and can be provided on the lower side of the first panel (11).

[0203] The frame (230) is provided inside the housing (200), but can be provided corresponding to the edge of the housing (200).

[0204] The frame (230) can support the first case (210). The upper side of the first case (210) can be mounted on the frame (230).

[0205] 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.

[0206] As illustrated in FIG. 7, the frame (230) may be provided with one or more weight sensors (150: R1, R2, R3, R4). The present embodiment describes a humidifier equipped with four weight sensors.

[0207] A plurality of weight sensors (150) may be provided on the lower side of the frame (230) and spaced apart at regular intervals.

[0208] 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).

[0209] A first case (210) can be contacted and mounted on a plurality of weight sensors (150).

[0210] As illustrated in FIG. 8, a protruding member (211) that protrudes from the outside of the first case (210) and protrudes in the downward direction of 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).

[0211] 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).

[0212] 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).

[0213] 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.

[0214] 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.

[0215] 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).

[0216] Referring to FIG. 9, a method of detecting weight using a plurality of weight sensors (150) is described.

[0217] Under no-load condition, the weight detected by multiple weight sensors is as follows.

[0218] Here, 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.

[0219] V AB =(R1 / (R1+R2))×V, V AD =(R4 / (R3+R4))×V,

[0220] E=V AB - V AD=((R1R3-R2R4) / (R1+R2)(R3+R4))×V

[0221] Under load, the weight detected by multiple weight sensors is as follows.

[0222] 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.

[0223] △E= (S1 / S2)×V

[0224] S1=(R1+△R1)×(R3+△R3) -(R2+△R2)×(R4+△R4)

[0225] S2= (R1+△R1+R2+△R2)×(R3+△R3+R4+△R4)

[0226] Weight = E - △E

[0298] Configuration 1 for controlling a heating source based on water temperature

[0299] The control unit (170) recognizes temperature information detected by the temperature sensor (160) based on receiving an ON command for the humidification mode through the input unit (111), and can recognize temperature information of the water stored in the water tank (310) based on the recognized temperature information.

[0300] Recognizing temperature information detected by the temperature sensor (160) based on receiving an ON command for the humidification mode through the input unit (111) may include recognizing the initial temperature information of the water stored in the water tank (310) at the start of the humidification operation.

[0301] The control unit (170) can recognize information on the reduction of the output of the heating source per humidification operation time based on the initial temperature information of the recognized water and control the output of the heating source (240) based on the information on the reduction of the output of the heating source per humidification operation time.

[0302] Here, the information on the reduction in output of the heating source for each humidification operation time corresponding to each initial temperature of the water may be information obtained by testing and stored in memory (172).

[0303] When the control unit (170) controls the output of the heating source, it is also possible to limit the reduction of the output of the heating source based on output reduction limit information.

[0304] The output reduction information of the heating source may include output reduction limit information. For example, the output reduction limit information may include 10% of the rated output, but the output limit is not limited thereto.

[0305] The control unit (170) may recognize an initial temperature range to which the initial temperature of the water belongs based on the recognized initial temperature information of the water, and may also recognize information on the reduction of the output of the heating source (240) for each humidification operation time based on the recognized initial temperature range.

[0306] Here, the information on the reduction in output of the heating source for each humidification operation time corresponding to each initial temperature range of the water may be information obtained by testing and stored in memory (172).

[0307] An example of a configuration for controlling the reduction of the output of the heating source (240) over a humidification operation time based on the initial temperature information of the water stored in the second water tank (312) is described.

[0308] As illustrated in FIG. 13, if the initial temperature of the water is 20°C, the control unit (170) recognizes information on the output reduction of the heating source (240) for each humidification operation time corresponding to the initial temperature of the water 20°C, and can control the output of the heating source (240) while reducing the output of the heating source (240) based on the recognized information on the output reduction of the heating source (240) for each humidification operation time.

[0309] More specifically, the control unit (170) can count the humidification operation time from the start of the humidification operation, control the output of the heating source (240) to the rated output until the counted humidification operation time reaches 2 hours, control the output of the heating source (240) to an output reduced by 6% from the rated output from the time the humidification operation time reaches 2 hours until the time

[0310] With reference to FIG. 13, an example of controlling the output of the heating source (240) based on the initial water temperature information of the second water tank (312) has been described, but it is also possible to control the output of the heating source (240) based on the initial water temperature information of the first water tank (311).

[0311] <Example 2 of controlling a heating source based on water temperature>

[0312] The control unit (170) periodically recognizes temperature information detected by the temperature sensor (160) during the performance of humidification operation, recognizes the temperature change value of the water stored in the water tank (310) based on the periodically recognized temperature information, and may also control the output of the heating source (240) based on the recognized temperature change value of the water. For example, the period may be 1 hour, but the time of the period is not limited thereto.

[0313] That is, the control unit (170) can recognize the temperature of the water detected by the temperature sensor (160) at one-hour intervals from the time the heating operation starts, and can recognize the change value of the water temperature at time intervals.

[0314] The control unit (170) can recognize output reduction information of the heating source (240) corresponding to the recognized temperature change value of the water and control the output of the heating source based on the output reduction information of the recognized heating source.

[0315] Here, the information on the reduction in output of the heating source corresponding to the change in water temperature is information obtained by testing and may be information stored in memory (172).

[0316] The control unit (170) recognizes the temperature change range to which the temperature change value of the water belongs based on the recognized temperature change value of the water, and it is also possible to recognize information on the reduction of the output of the heating source based on the recognized temperature change range. For example, the temperature change range of the water may include a first temperature change range in which the temperature change value is from 25℃ to 20.1℃, a second temperature change range in which the temperature change value is from 20℃ to 15.1℃, a third temperature change range in which the temperature change value is from 15℃ to 10.1℃, and a fourth temperature change range in which the temperature change value is 10℃ or less.

[0317] Here, the output reduction information of the heating source corresponding to each range of water temperature change is information obtained by testing and may be information stored in memory (172).

[0318] An example of a configuration for controlling the reduction of the output of a heating source (240) based on the temperature change value of the water stored in the first water tank (311) is described.

[0319] As illustrated in FIG. 14, the control unit (170) recognizes the temperature (20°C) of the water stored in the first water tank (311) based on temperature information detected by the temperature sensor (160) at the start of the humidification operation, counts the humidification operation time, and when the counted humidification operation time reaches 1 hour, recognizes the temperature (40°C) of the water stored in the first water tank (311) based on temperature information detected by the temperature sensor (160), recognizes the temperature change value (20°C) between the temperature of the water at the start of the humidification operation and the temperature of the water at the time when the humidification operation time reaches 1 hour, and can control the output of the heating source to the rated output based on the recognized temperature change value.

[0320] When the counted humidification operation time reaches 2 hours, the control unit (170) recognizes the temperature (55℃) of the water stored in the first water tank (311) based on temperature information detected by the temperature sensor (160), recognizes the temperature change value (15℃) between the water temperature at the time when the humidification operation time reaches 1 hour and the water temperature at the time when the humidification operation time reaches 2 hours, and can control the output of the heating source to the rated output based on the recognized temperature change value.

[0321] When the counted humidification operation time reaches 3 hours, the control unit (170) recognizes the temperature (65℃) of the water stored in the first water tank (311) based on temperature information detected by the temperature sensor (160), recognizes the temperature change value (10℃) between the water temperature at the time when the humidification operation time reaches 2 hours and the water temperature at the time when the humidification operation time reaches 3 hours, and can control the output of the heating source (240) to an output reduced by 6% from the rated output based on the recognized temperature change value.

[0322] In this way, the control unit (170) periodically recognizes the temperature of the water stored in the first water tank (311), recognizes the temperature change value between the water temperature recognized in the previous cycle and the water temperature recognized in the current cycle, and can control the output of the heating source (240) to a rated output or an output reduced from the rated output based on the recognized temperature change value.

[0323] As shown in FIG. 15, by controlling the output of the heating source (240) to decrease based on the temperature change value of the water stored in the first water tank, it can be seen that the amount of humidification is maintained constant for each humidification operation time and the power consumption of the heating source (240) is reduced.

[0324] Maintaining a constant humidification amount over time may mean that the humidification amount is maintained at a constant level periodically.

[0325] With reference to FIG. 14, an example of controlling the output of the heating source (240) based on the temperature change value of the water in the first tank (311) has been described, but it is also possible to control the output of the heating source (240) based on the temperature change value of the water in the second tank (312).
