Description

Technical Field

[0001] The present invention relates to a humidifier, and more specifically, to a humidifier that supplies humidified clean air. Background Technology

[0002] A humidifier is a device that supplies humidified air to a room. Humidifiers have a water tank for storing water and are classified according to their humidification method as ultrasonic, heating, natural vaporization, or a combination of both.

[0003] A humidifier is a device that vaporizes water and releases humidified air with a high water content. Humidifiers can generate humidified air by vaporizing water through natural vaporization, heating vaporization, or ultrasonic vibration.

[0004] Each vaporization method has its own advantages and disadvantages.

[0005] In the case of natural vaporization, there is a problem that users must frequently manage the humidification medium they are using.

[0006] Ultrasonic humidifiers use a vibrator that generates vibrations through ultrasonic waves. These vibrations spray water into microparticles, offering the advantage of a large spray volume. However, when humidifying water through ultrasonic vibration, there are issues such as sluggish airflow within the room. Furthermore, using unsterilized water can result in uncomfortable humidified air flowing into the room. Additionally, ultrasonic vibrators are susceptible to thermal fragility at high temperatures.

[0007] If hot, humidified air is directly discharged during heating and vaporization, a safety accident may occur.

[0008] Existing literature, Korean Patent No. KR10-0158806, discloses a heater-type ultrasonic humidifier for humidifying and heating water.

[0009] Typically, air purifiers and humidifiers are manufactured and used as separate products. However, to meet various consumer needs, products that combine humidification and air purification functions have emerged. For example, existing literature, Korean Patent Publication No. KR10-2005-0024044, discloses an air purification and humidification device.

[0010] On the other hand, as described in existing literature, the cleanliness of a humidifier or device that provides humidification will decrease if there is standing water or residual moisture inside. Furthermore, hygiene management is also required when storing humidifiers or devices that are not in use.

[0011] In addition, it is necessary to monitor whether water is supplied and the status of the water tank in order to control the operation mode and situation appropriately. Summary of the Invention

[0012] The purpose of this invention is to solve the above-mentioned problems and other issues.

[0013] The purpose of this invention is to provide a humidifier that can accurately determine whether a water tank is installed and perform corresponding actions.

[0116] The water tank 100 includes: an inner water tank 102 forming a space for storing water; and an outer water tank 160 disposed to cover the outer side of the inner water tank 102. The inner water tank 102 may be disposed inside the outer water tank 160. When the inner water tank 102 is disposed inside the outer water tank 160, it may be configured such that the outer peripheral surface of the inner water tank 102 contacts the inner peripheral surface of the outer water tank 160.

[0117] Reference Figure 5 The inner water tank 102 includes: an inner water tank body 104 forming a space for storing water; a handle 108 disposed on the upper side of the inner water tank body 104; and a connector 120 disposed on the lower side of the inner water tank body 104, connecting the inner water tank body 104 to the supply pipe 230 (see below). Figure 10 )connect.

[0118] Reference Figure 5 The inner water tank 102 is equipped with a water softening device 140 for softening the water inside the inner water tank 102. The water softening device 140 includes: a water softening device cover 142, which forms a space for arranging an ion exchange resin filter (not shown) inside; and a cover 150, which covers the upper side of the water softening device cover 142.

[0119] A plurality of cover holes 150b can be formed on the cover 150, and a plurality of cover holes (not shown) can be formed on the cover 142 of the water softener.

[0120] The inner water tank body 104 can be formed in a generally cylindrical shape. The inner water tank body 104 can have an opening at the top. A lower hole 106 for discharging stored water can be formed on the lower surface of the inner water tank body 104. (See reference...) Figure 5 The inner water tank body 104 can have a shape in which the diameter of the inside of the water tank gradually decreases from the top to the bottom.

[0121] A lower hole 106 can be formed on the lower surface of the inner water tank body 104. A connector 120 can be fixedly disposed in the lower hole 106. Water stored in the inner water tank 102 can flow to the supply pipe 230 through the connector 120 installed in the lower hole 106.

[0122] The water softener 140 can be fixedly installed inside the inner water tank 102. The water softener 140 can be equipped with an ion exchange resin (not shown) that removes ions from the water flowing into the inner water tank 102. The water softener 140 can include a gasket 152 on one side of its peripheral surface that seals the inner peripheral surface of the inner water tank 102 and the outer peripheral surface of the water softener 140.

[0123] Referring to the enlarged view, the washer 152 disposed at the upper end of the water softener 140 can be configured to contact the inner circumferential surface of the inner water tank 102. Therefore, water is prevented from flowing through the space between the inner water tank 102 and the water softener 140 without passing through the interior of the water softener 140. Water flowing from the upper side of the inner water tank 102 and towards the lower hole 106 of the inner water tank 102 can flow through the water softener 140.

[0124] The handle 108 includes: a handle fixing part 112, which is fixedly disposed at the upper end of the inner water tank body 104; and a handle bar 110, which is disposed across the upper side of the inner water tank body 104.

[0126] Reference Figure 5 The connector 120 includes: a connector body 121 configured to pass through a lower hole 106 in the inner water tank body 104; a connector retainer 132 connected to the connector body 121 to fix the configuration of the connector body 121; and a connector valve 130 configured inside the connector body 121 to open and close the internal flow path of the connector body 121.

[0127] Reference Figure 5The connector body 121 includes: a connector plate 122 disposed inside the inner water tank body 104; and a connector tube 128 disposed through a lower hole 106 in the inner water tank body 104 and forming an internal flow path 128a. The connector plate 122 is disposed on the upper side of the lower surface of the inner water tank body 104.

[0128] The connector plate 122 may have a structure that contacts the lower part of the water softener 140, thereby securing the water softener 140 in place. Upward-protruding fixing ribs 126a and 126b may be provided in the connector plate 122.

[0129] Reference Figure 5 The fixing ribs 126a and 126b may include a first fixing rib 126a and a second fixing rib 126b arranged radially spaced from the first fixing rib 126a. A lower protrusion 148 of the water softener 140 may be arranged in the space between the first fixing rib 126a and the second fixing rib 126b. The first fixing rib 126a and the second fixing rib 126b can prevent the water softener 140, which is disposed inside the inner water tank 102, from moving in a direction perpendicular to the vertical direction.

[0130] The connector plate 122 is provided with an edge wall 124 that is radially outward and protrudes upward compared to the fixing ribs 126a and 126b. (Refer to...) Figure 5 A hook hole 124a for inserting the hook 149 of the water softener 140 can be formed in the edge wall 124.

[0131] The connector tube 128 may have a structure extending downward from the center of the connector plate 122. The connector tube 128 is configured to penetrate the lower hole 106 of the inner water tank body 104. An internal flow path 128a for water flow inside the inner water tank 102 can be formed inside the connector tube 128. A connector valve 130 for opening and closing the internal flow path 128a is disposed inside the connector tube 128.

[0132] Connector valve 130 can be configured to move in the up-down direction inside connector tube 128. When connector 120 is connected to supply tube 230, which will be described below, connector valve 130 can move upward to open internal flow path 128a.

[0133] The connector retainer 132 is fixedly disposed on the outer periphery of the connector tube 128. The connector retainer 132 can be disposed on the lower side of the lower surface of the inner water tank body 104. Therefore, the connector retainer 132 can be connected to the connector tube 128, thereby fixing the configuration of the connector body 121.

[0134] Reference Figure 5The inner water tank 102 may include a sealing gasket 114 mounted on the periphery of the inner water tank body 104 forming the lower hole 106. The sealing gasket 114 may be formed of a rubber material. The sealing gasket 114 may be configured to contact the connector plate 122 on its upper side and the connector retainer 132 on its lower side.

[0135] The sealing gasket 114 prevents contact between the inner water tank body 104 and the connector body 121. The sealing gasket 114 also prevents contact between the inner water tank body 104 and the connector retainer 132. The sealing gasket 114 seals the space between the connector plate 122 and the lower wall 105 of the inner water tank body 104. Additionally, the sealing gasket 114 seals the space between the connector retainer 132 and the lower wall 105 of the inner water tank body 104. In other words, the sealing gasket 114 provides a double layer of protection against water present inside the inner water tank 102 leaking through the outside of the connector 120.

[0136] An inner seal 136 may be configured on the outer periphery of the connector tube 128. The inner seal 136 can seal the space between the connector 120 and the supply tube 230.

[0137] An outer seal 134 may be configured on the outer periphery of the connector retainer 132. The outer seal 134 may be configured to contact one side of the outer water tank 160 and / or the inner shell 180, which will be described below.

[0138] Reference Figure 4 The water tank cover 14 can be disposed on the upper side of the inner water tank 102. The water tank cover 14 can be configured to be disposed on the discharge grille 12. The water tank cover 14 may include a central cover 16 and a peripheral cover 18 disposed on the outer periphery of the central cover 16.

[0139] The peripheral cover 18 can be positioned above the discharge grille 12 to maintain the configuration of the trough cover 14. The peripheral cover 18 can have an annular structure. The peripheral cover 18 can have a structure that slopes downwards towards the radially inward direction. Therefore, when supplying water upwards, the water can flow towards the central cover 16.

[0140] The central cover 16 may have an upward-protruding shape. Therefore, when water is supplied to the upper side of the central cover 16, the water can flow towards the outer periphery of the central cover 16. A water supply hole 20 for supplying water to the inner water tank 102 can be formed between the central cover 16 and the peripheral cover 18. The water supplied to the water supply hole 20 can flow towards the upper side of the handle fixing part 112 of the handle 108 of the inner water tank 102.

[0141] The sink cover 14 can be configured to be spaced upward from the inner sink 102 and / or the outer sink 160. Therefore, during water supply, the force of water pressing the sink cover 14 downward is not transmitted to the inner sink 102 or the outer sink 160.

[0142] The outer water tank 160 is disposed on the outer periphery of the inner water tank 102. The outer water tank 160 can be configured to contact the outer periphery of the inner water tank 102. Therefore, condensation generated on the outer periphery of the inner water tank 102 can be minimized.

[0143] The upper end 162 of the outer water tank 160 can be formed to be separated from the inner water tank 102. That is, the upper end 162 of the outer water tank 160 can be formed to have a larger ratio of lateral radial expansion as it goes upward.

[0144] The outer water tank 160 may also have a cylindrical shape with an opening on the upper side. A through hole 164 through which the connector 120 of the inner water tank 102 passes can be formed on the lower surface of the outer water tank 160. The through hole 164 is formed to be larger than the lower hole 106 of the inner water tank 102.

[0145] Reference Figure 6 The lower surface of the outer water tank 160 may be configured with: a lower protrusion 166 protruding downward from the periphery of the through hole 164; a pair of first water tank protrusions 170a and 170b protruding downward from the lower surface of the outer water tank 160; and a second water tank protrusion 168 protruding downward from the lower surface of the outer water tank 160.

[0146] A lower protrusion 166 is disposed around the periphery of the through hole 164. The lower protrusion 166 extends downward from the inner peripheral end of the lower surface of the outer water tank 160. The lower protrusion 166 may have an annular structure. An outer seal 134 is disposed in contact with the inner peripheral surface of the lower protrusion 166.

[0147] Reference Figure 6 A pair of first water tank protrusions 170a and 170b can be configured in opposite directions relative to the through hole 164. The pair of first water tank protrusions 170a and 170b can transfer the load of the inner water tank 102 and the outer water tank 160 to the weight sensors 212a and 212b of the intermediate tray 200, which will be described below. The pair of first water tank protrusions 170a and 170b can directly transfer the load of the inner water tank 102 and the outer water tank 160 to the weight sensors 212a and 212b, or indirectly through the inner shell 180.

[0148] The second water tank protrusion 168 can be configured between a pair of first water tank protrusions 170a and 170b.

[0149] The inner shell 180 can be configured separately from the outer water tank 160. The inner shell 180 is configured separately from the water tank 100. A first discharge path 32 for humidifying airflow is formed between the inner shell 180 and the outer water tank 160.

[0150] Reference Figure 8 The inner shell 180 is configured separately from the outer shell 22. The inner shell 180 can form a second discharge path 34 for filtered airflow between itself and the outer shell 22.

[0151] The inner shell 180 may have a cylindrical shape with an opening on the upper side. The inner shell 180 may have a larger diameter than the outer water tank 160. Like the upper end 162 of the outer water tank 160, the upper end of the inner shell 180 is formed with a large radial expansion ratio.

[0152] A shell through-hole 184 is formed on the lower surface of the inner shell 180. The shell through-hole 184 is disposed below the through-hole 164 of the outer water tank 160. A connector 120 can be disposed in the shell through-hole 184.

[0153] The inner shell 180 can be made of a transparent material. (See reference) Figure 8 In the inner shell 180, an upper protrusion 186 may be configured to protrude upward from the portion forming the shell through hole 184. The upper protrusion 186 of the inner shell 180 may be configured to contact the lower protrusion 166 of the outer water tank 160.

[0154] The size of the shell through-hole 184 of the inner shell 180 can be made smaller than the size of the through-hole 164 of the outer water tank 160. The upper protrusion 186 can be disposed inside the lower protrusion 166 of the outer water tank 160. That is, the outer peripheral surface of the upper protrusion 186 is disposed facing the inner peripheral surface of the lower protrusion 166 of the outer water tank 160.

[0155] An external seal 134 can be configured on the upper side of the upper protrusion 186.

[0156] Within the inner shell 180, a pair of first shell protrusions 188a and 188b may be configured to mount a pair of first water tank protrusions 170a and 170b of the outer water tank 160. The pair of first shell protrusions 188a and 188b may have a structure that protrudes downwards from the lower surface of the inner shell 180. Each of the pair of first shell protrusions 188a and 188b forms a space for insertion of the pair of first water tank protrusions 170a and 170b.

[0157] A pair of first housing protrusions 188a and 188b are each disposed above the weight sensors 212a and 212b located on the intermediate tray 200. Therefore, the pair of first housing protrusions 188a and 188b can transfer the load of the inner water tank 102 and the outer water tank 160 to the weight sensors 212a and 212b.

[0158] A second housing protrusion 190 can be configured within the inner housing 180 to mount the second water tank protrusion 168 of the outer water tank 160. A space for insertion of the second water tank protrusion 168 can be formed within the second housing protrusion 190.

[0159] Reference Figure 8An exhaust connection pipe 192 is disposed within the inner shell 180 to guide humidified air discharged from the second humidification tank 350 to the first discharge flow path 32. The exhaust connection pipe 192 has a structure extending downward from the lower surface of the inner shell 180. The exhaust connection pipe 192 may have a shape corresponding to the exhaust pipe 382 described below. The exhaust connection pipe 192 has a generally elliptical shape.

[0160] Reference Figure 8 The lower end of the exhaust connection pipe 192 can be connected to the upper end of the exhaust pipe 382. The lower end of the exhaust connection pipe 192 can be positioned further inward than the upper end of the exhaust pipe 382. The lower end of the exhaust connection pipe 192 can form a step for protruding inward toward the exhaust pipe 382. The lower end of the exhaust connection pipe 192 forms an exhaust pipe connection hole 194 that opens downward.

[0161] The humidifier includes an intermediate tray 200 that divides the area into a water tank 100 and an area into a humidification module. The intermediate tray 200 can detect the water level in the water tank 100. The intermediate tray 200 can also illuminate the emitted humidified air.

[0162] Reference Figure 6 The intermediate tray 200 is positioned below the water tank 100. The intermediate tray 200 is positioned above either the second humidifying water tank 350 or the first humidifying water tank 300, which will be described below. Weight sensors 212a and 212b, which detect the water level of the water tank 100 by weight, can be mounted on the intermediate tray 200.

[0164] Reference Figure 7a The intermediate tray 200 includes a tray plate 202 and a lamp cover 218 disposed on the outer periphery of the tray plate 202 and having a lamp 216 disposed inside.

[0165] A first hole 204 is formed on one side of the tray plate 202 for the supply pipe 230 to pass through. The first hole 204 may be formed at the center of the tray plate 202. A portion of the supply pipe 230 is disposed above the first hole 204. The connector 120 of the inner water tank 102 may be connected to the supply pipe 230 disposed above the first hole 204.

[0166] Reference Figure 7aA first flange 206 protruding towards the upper side of the tray plate 202 is disposed around the periphery of the first hole 204. Therefore, it is possible to prevent water flowing into the upper side of the tray plate 202 from flowing towards the lower side of the intermediate tray 200.

[0167] On the other side of the tray plate 202, a second hole 208 is formed for the flow of humidified air discharged from the second humidification water tank 350. A second flange 210 protruding towards the upper side of the tray plate 202 is disposed around the periphery of the second hole 208. The second flange 210 can prevent water flowing into the upper side of the tray plate 202 from flowing through the second hole 208 to the lower side of the intermediate tray 200.

[0168] The lampshade body 218 is disposed along the periphery of the tray plate 202. The lampshade body 218 may be formed into a ring shape. A lamp 216 that emits upward light may be disposed inside the lampshade body 218. One side of the lampshade body 218 may be formed of a material through which light emitted from the lamp 216 passes.

[0169] The intermediate tray 200 can be configured to cover the upper side of the first humidifying water tank 300 and the second humidifying water tank 350. The intermediate tray 200 can be combined with the humidifying module cover 410, which will be described below, to form a space inside for arranging the first humidifying water tank 300 and the second humidifying water tank 350.

The detection sensor 234 can detect the water quality, thereby detecting when the water softening device 140 disposed in the water tank 100 needs to be replaced.

[0203] The humidifier of the present invention includes a supply pipe 230 for supplying water stored in a water tank 100 to a first humidifying water tank 300. The supply pipe 230 is disposed between the water tank 100 and the first humidifying water tank 300. The supply pipe 230 can temporarily store water discharged from the water tank 100 and supplied to the first humidifying water tank 300.

[0212] Depending on the configuration of the first valve 400, the flow path formed at the end of the supply pipe 230 can be opened or closed. The first valve 400 can supply or stop the supply of water to the first humidifying water tank wall 302 from the supply pipe 230.

[0213] A first valve 400 may be configured on the upper side of the first humidification water tank 300 to supply or interrupt the supply of water present in the supply pipe 230 to the first humidification water tank 300.

[0214] A first supply port 325 may be formed in the first upper cover 322. Water present in the supply chamber 232 flows through the first supply port 325 to the first humidification water tank 300 side. The first valve 400 supplies water stored in the supply chamber 232 to the first humidification water tank 300 by opening and closing the first supply port 325.

[0215] A water quality sensor 234 is installed in the supply pipe 230 to detect the water quality present inside the supply chamber 232. The sensor 234 is located on one side of the intermediate supply pipe 230b. The sensor 234 can also be located on the upper part of the intermediate supply pipe 230b.

[0216] The detection sensor 234 can be configured on the upper part of the intermediate supply pipe 230b to quickly detect the water quality of the water supplied from the water tank 100. That is, when the water present in the supply chamber 232 drops and water flows into the water tank 100, the water quality of the water flowing into the water tank 100 can be detected.

[0217] The first humidifying water tank 300 has a first chamber 300a, which forms a space for storing and heating water.

The heating element 342 may be formed as an annular shape with an opening on one side. The heating element 342 may be disposed inside the lower water tank wall 308.

[0223] A heating plate 344 is disposed above the heating element 342, transferring the heat generated by the heating element 342 to the water inside the first humidifying water tank 300. The heating plate 344 may be configured to cover the heating element 342. A portion of the heating plate 344 may be configured to protrude into the lower water tank wall 308 to cover the heating element 342. The heating plate 344 disposed inside the lower water tank wall 308 may be spaced apart from the inner peripheral surface of the lower water tank wall 308.

[0224] Reference Figure 12 The intermediate water tank wall 306 is positioned above the lower water tank wall 308. The intermediate water tank wall 306 has a smaller diameter, thus creating a space within the humidification module housing 410 for arranging the second valve 402. The smaller diameter of the intermediate water tank wall 306 also creates a space within the humidification module housing 410 for arranging the first connecting pipe 390.

[0225] Reference Figures 10 to 12 A first temperature sensor 336 is disposed on one side of the intermediate water tank wall 306. A recovery inlet hole 314 for water flowing into the second connecting pipe 392 is formed on one side of the intermediate water tank wall 306. An outlet hole 316 for water flowing out to the first connecting pipe 390 can be formed on one side of the intermediate water tank wall 306.

[0226] The outflow orifice 316 can be configured at a position higher than the recycling inflow orifice 314. The first temperature sensor 336 can be configured at a position higher than the recycling inflow orifice 314. The outflow orifice 316 can be configured at a position higher than or at the same height as the first temperature sensor 336.

[0227] Therefore, the first temperature sensor 336 can detect the temperature change as the water supplied to the first humidifying water tank 300 is heated. Additionally, the first temperature sensor 336 can detect the temperature of the water stored in the first chamber 300a of the first humidifying water tank 300 after a portion of the water stored inside the first humidifying water tank 300 is supplied to the second humidifying water tank 350.

[0228] The first temperature sensor 336 can detect temperature changes inside the first humidification tank 300. The first temperature sensor 336 can also detect abnormal operation of the heater 340 inside the first humidification tank 300.

[0229] The upper water tank wall 304 can extend upwards towards the middle water tank wall 306. The length of the upper water tank wall 304 extending in the vertical direction can be greater than the length of the middle water tank wall 306 extending in the vertical direction. The size of the internal space formed by the upper water tank wall 304 can be greater than the size of the internal space formed by the middle water tank wall 306 and the lower water tank wall 308.

[0230] Reference Figures 10 to 12 A first water level sensor 338 is disposed on one side of the upper water tank wall 304. The first water level sensor 338 is disposed above the first temperature sensor 336. The first water level sensor 338 can detect the water level inside the first humidification water tank 300. The first water level sensor 338 can detect the normal water level of the first humidification water tank 300. The normal water level of the first humidification water tank 300 can refer to the area between the upper end of the set water level supplied to the first humidification water tank 300 and the lower end of the minimum water level required for the operation of the heater 340.

[0231] The first humidifying water tank 300 may include upper covers 322 and 324 disposed on the upper side of the first humidifying water tank wall 302. The upper covers 322 and 324 are disposed on the upper side of the upper water tank wall 304.

[0232] The upper covers 322 and 324 may be configured to cover at least a portion of the upper side of the first humidification tank wall 302. The upper covers 322 and 324 may include a first upper cover 322 and a second upper cover 326 disposed below the first upper cover 322.

[0233] Reference Figure 12 and Figure 13 The first upper cover 322 is disposed above the second upper cover 326. The first upper cover 322 can divide the first humidification tank wall 302 and the supply pipe 230. The first upper cover 322 can form one side for forming the supply chamber 232 inside the supply pipe 230.

[0234] Reference Figure 12 and Figure 13 A first supply hole 325 for water flow in the supply chamber 232 is formed on the first upper cover 322. A first valve 400 can be disposed above the first supply hole 325 to open and close the first supply hole 325. The first upper cover 322 is disposed upwardly spaced from the upper end of the upper water tank wall 304.

[0235] The first upper cover 322 may have a structure that connects to the exhaust pipe 382, ​​which will be described below. The first upper cover 322 may be integrally formed with the exhaust pipe 382. The first upper cover 322 may have a smaller area than the second upper cover 326.

[0236] The first upper cover 322 can be configured to be spaced apart from the second upper cover 326. That is, the first upper cover 322 can be configured to be spaced apart from the upper side of the second upper cover 326.

[0237] A portion of the first upper cover 322 may form part of the supply tube 230. A cavity 324 recessed downward in the region forming the supply tube 230 may be formed on the first upper cover 322.

[0238] Reference Figure 12 and Figure 13 The second upper cover 326 can be configured to cover the first supply hole 325 formed in the first upper cover 322. A second supply hole 330 can be formed on the second upper cover 326 to deliver water flowing through the first supply hole 325 to the first humidifying water tank 300. The second supply hole 330 is spaced apart from the first supply hole 325 in a direction perpendicular to the vertical direction.

[0239] Reference Figure 11 A supply flow path 328 can be formed between the second upper cover 326 and the first upper cover 322, allowing water to flow from the first supply hole 325 to the second supply hole 330. The second upper cover 326 may be provided with an upwardly protruding supply flow path rib 331 to form the supply flow path 328. The supply flow path rib 331 may be configured to protrude upwards from the second upper cover 326 and contact the lower surface of the first upper cover 322.

[0240] The supply flow path 328 can extend in a direction different from that of the cavity 324. As an example, the supply flow path 328 can extend in a direction perpendicular to that of the cavity 324.

[0241] Reference Figure 12 and Figure 13A first connecting hole 311a is formed on the second upper cover 326. The first connecting hole 311a allows the first humidifying water tank 300 to be connected to the second humidifying water tank 350. That is, the humidified air generated in the first humidifying water tank 300 can flow to the second humidifying water tank 350 through the first connecting hole 311a.

[0242] The first connecting hole 311a can have a structure that opens in the upward and downward direction. Therefore, the humidified air generated by the heater 340 inside the first humidification tank 300 can flow upward through the first connecting hole 311a.

[0243] The second upper cover 326 may include an upper rib 333 extending upward from the periphery of the first connecting hole 311a. The upper rib 333 may have a structure that protrudes upward from the periphery of the second upper cover 326 forming the first connecting hole 311a.

[0244] The upper cover 312 can be disposed on the upper side of the second upper cover 326. The upper cover 312 can have a structure connected to the upper rib 333. The upper cover 312 and the upper rib 333 can form a communicating flow path 311 internally.

[0245] The connecting flow path 311 can connect the first connecting hole 311a formed in the first humidifying water tank 300 and the second connecting hole 311b formed in the second humidifying water tank 350. The connecting flow path 311 can be disposed on the upper side of the first humidifying water tank 300. Therefore, the humidifying air generated and rising in the first humidifying water tank 300 can flow to the connecting flow path 311 through the first connecting hole 311a.

[0246] The connecting flow path 311 can be formed by the upper rib 333 of the second upper cover 326 and the upper cover 312. The connecting flow path 311 can extend in a direction horizontal to the second connecting hole 311b.

[0247] The interior of the second humidifying water tank 350 may form a second chamber 350a for storing water and atomizing it.

[0248] Reference Figure 12 and Figure 13 The second humidifying water tank 350 may include a second humidifying water tank wall 352 and a vibrator 370. The second humidifying water tank wall 352 forms a second chamber 350a. The vibrator 370 is disposed on the lower side of the second humidifying water tank wall 352 and vibrates to atomize the water inside the second humidifying water tank wall 352.

[0249] The second humidifying water tank wall 352 may have a columnar shape that forms an internal space. A vibrator 370 is disposed on the lower side of the second humidifying water tank wall 352. The second humidifying water tank wall 352 may have a shape in which the cross-sectional area formed in the horizontal direction increases towards the upper side.

[0250] The upper end of the second humidifying water tank wall 352 is formed to be higher than the upper end of the first humidifying water tank wall 302.

[0251] A vibrator 370 is installed on the lower surface of the second humidification tank wall 352. (Refer to...) Figure 12 An inlet hole 358 for supplying water to the first humidifying water tank wall 302 can be formed on one side of the second humidifying water tank wall 352. A return outlet hole 360 ​​for water stored inside the second humidifying water tank 350 to flow to the first humidifying water tank 300 can also be formed on one side of the second humidifying water tank wall 352.

[0252] The inlet hole 358 can be formed at a position lower than the outlet hole 316 formed in the first humidification tank wall 302. The recovery outlet hole 360 ​​can be formed at a position lower than the inlet hole 358.

[0253] Reference Figure 12 A vibrator 370 can be disposed on the lower surface of the second humidifying water tank 350. A recovery trough 361 is formed on one side of the wall 352 of the second humidifying water tank, extending from the area where the recovery discharge hole 360 ​​is formed towards the periphery. The recovery trough 361 can be formed on one side of the vibrator 370. That is, the recovery trough 361 is disposed on one side of the vibrator 370 provided on the lower surface of the second humidifying water tank 350. In other words, the recovery trough 361 can form a space at the lower end of the inner side of the wall 352 of the second humidifying water tank.

[0254] The recovery discharge port 360 is formed at a position lower than the recovery inflow port 314 formed on the first humidification tank wall 302.

[0255] Reference Figure 13 A second temperature sensor 364 is disposed on one side of the peripheral surface of the second humidification water tank 350. The second temperature sensor 364 can be disposed at a position higher than the recovery discharge port 360. The second temperature sensor 364 can also be disposed at a position lower than or at the same height as the inflow port 358.

[0256] The second temperature sensor 364 can detect the temperature of the water supplied to the second humidification tank 350. Therefore, the second temperature sensor 364 can detect whether water above a set temperature is supplied to the second humidification tank 350.

[0257] Reference Figure 9 and Figure 13A second water level sensor 366 is disposed on one side of the peripheral wall of the second humidification water tank 350. The second water level sensor 366 detects the water level inside the second humidification water tank 350. The second water level sensor 366 can detect the minimum water level inside the second humidification water tank 350 at which the vibrator 370 can operate. Additionally, the second water level sensor 366 can detect the amount of water stored inside the second humidification water tank 350. The second water level sensor 366 can detect the optimal water level required for the vibrator 370 to operate.

[0258] Reference Figure 13 A water level sensor cover 368 may be disposed inside the second humidifying water tank 350. The water level sensor cover 368 may be disposed at a constant interval from the second water level sensor 366. The water level sensor cover 368 may be disposed between the second water level sensor 366 and the vibrator 370. The water level sensor cover 368 may have a structure that protrudes upward from the lower surface of the second humidifying water tank 350.

[0259] Even if the water level inside the second humidification tank 350 changes due to the vibrator 370, the second water level sensor 366 can detect a more accurate water level through the water level sensor cover 368.

[0260] A second connecting hole 311b is formed at the upper end of the peripheral wall of the second humidifying water tank 350. The second connecting hole 311b opens toward the direction in which the first humidifying water tank 300 is disposed.

[0261] Reference Figure 12 and Figure 13 The second connecting hole 311b is connected to the connecting flow path 311. The second connecting hole 311b is open in the horizontal direction.

[0262] The lower surface of the second humidifying water tank 350 may be equipped with two vibrators 370. The two vibrators 370 are spaced apart from each other in a direction perpendicular to the vertical direction.

[0263] The vibrator 370 includes a vibrating element 372 that generates vibrations and a vibrating element cover 374 disposed on the upper side of the vibrating element 372. The vibrating element cover 374 is configured to contact water stored inside the second humidification water tank 350. The vibrating element cover 374 transmits the vibrations generated by the vibrating element 372 to the water stored inside the second humidification water tank 350.

[0264] The vibrator 370 uses water stored in the second humidification tank 350 to generate humidified air.

[0265] Reference Figure 12 and Figure 13The second humidifying water tank 350 includes a humidifying water tank cover 380 disposed on the upper side of the second humidifying water tank wall 352. The humidifying water tank cover 380 can supply the humidified air generated in the second humidifying water tank 350 to the first discharge flow path 32.

[0266] The humidifier water tank cover 380 includes an exhaust pipe 382 that supplies humidifying air to the upper side. The exhaust pipe 382 may have a structure that extends upward from the humidifier water tank cover 380. The exhaust pipe 382 has a generally elliptical column shape.

[0267] Reference Figure 12 and Figure 13 The exhaust pipe 382 is positioned above a pair of vibrators 370. Therefore, the humidified air generated in the vibrators 370 can flow rapidly to the exhaust pipe 382. Additionally, when water stored in the second chamber 350a of the second humidification tank 350 splashes upwards due to the vibrators 370, it can move into the exhaust pipe 382.

[0268] The upper end of the exhaust pipe 382 can be configured to connect with the intermediate tray 200 (see reference). Figure 8 The upper end of the exhaust pipe 382 can be configured to directly contact the intermediate tray 200, or indirectly contact it through a separate sealing member 388.

[0269] The lower end of the exhaust pipe 382 has an exhaust pipe inlet 382a (or exhaust hole). The upper end of the exhaust pipe 382 has an exhaust pipe outlet 382b. An exhaust pipe flow path 383 can be formed between the exhaust pipe inlet 382a and the exhaust pipe outlet 382b.

[0270] An air supply hole 387 is formed on one side of the humidifying water tank cover 380. Outside air can flow into the inside of the second humidifying water tank 350 through the air supply hole 387. The air supply hole 387 may have an upward opening shape.

[0271] The humidifying water tank cover 380 includes an air guide cover 386 that supplies air flowing through the air supply path 70 to the second humidifying water tank 350. The air guide cover 386 directs a portion of the air flowing to the outside of the humidifying module housing 410 through an air supply port 387 to the inside of the second humidifying water tank 350.

[0272] The air guide cover 386 can guide the airflow that is directed to the outside of the second humidification water tank 350 to the inside of the second humidification water tank 350.

[0273] The air guide cover 386 is configured to be spaced upward from the air supply port 387 and has a structure extending horizontally from the exhaust pipe 382. The air guide cover 386 extends from the peripheral wall of the exhaust pipe 382 and is configured at a position spaced upward from the upper end of the second humidification tank wall 352.

[0274] Reference Figure 12 and Figure 13 The air guide cover 386 includes a horizontal wall 386a extending horizontally from the exhaust pipe 382 and a vertical wall 386b extending downward from the end of the horizontal wall 386a. The horizontal wall 386a may be configured to be spaced upward from the air supply port 387 and the upper end of the second humidification tank wall 352.

[0275] The vertical wall 386b is configured outwardly from the peripheral wall of the second humidifying water tank 350. The vertical wall 386b is also configured outwardly from the peripheral wall of the humidifying module cover 410. The lower end of the vertical wall 386b may be located lower than the upper end of the second humidifying water tank wall 352.

[0276] A portion of the air flowing in the air supply path 70 flows upward through the space between the humidification module cover 410 and the vertical wall 386b, flows along the horizontal wall 386a to the upper side of the second humidification water tank 350, and then flows along the air supply hole 387 to the lower part of the second chamber 350a of the second humidification water tank 350.

[0277] The lower side of the air guide cover 386 can form an air inflow path for air flow. The air inflow path is disposed above the connecting path 311. The air supply port 387 can be disposed above the connecting path 311.

[0278] The humidifying water tank cover 380 includes a lower extension wall 384 that protrudes from the humidifying water tank cover 380 toward the interior of the second humidifying water tank 350. The lower extension wall 384 extends downward from the humidifying water tank cover 380. The lower extension wall 384 has a structure that protrudes downward from the area forming the exhaust pipe 382.

[0279] Reference Figure 12 and Figure 13 The lower extension wall 384 is disposed between the exhaust pipe inlet 382a and the air supply port 387. The lower extension wall 384 may have a shape that curves towards the exhaust pipe inlet 382a when viewed from above. Therefore, air flowing into the inner side of the second humidification tank 350 through the air supply port 387 can flow along the lower part of the second chamber 350a and the inner circumferential surface of the second humidification tank wall 352.

[0280] The lower extension wall 384 can extend downward between the exhaust pipe inlet 382a and the air supply port 387. The lower extension wall 384 can direct the air flowing into the inner side of the second humidification water tank 350 through the air supply port 387 to the lower part of the second chamber 350a.

[0281] No lower extension wall 384 is provided in the direction forming the second connecting hole 311b. That is, no lower extension wall 384 is provided in the direction of the opening of the second connecting hole 311b. Therefore, the humidified air flowing into the second humidifying water tank 350 through the second connecting hole 311b can flow to the exhaust pipe inlet 382a of the exhaust pipe 382.

[0282] The lower extension wall 384 includes: a first lower extension wall 384a, which extends downward from the exhaust pipe 382 in the portion forming the air supply port 387; a second lower extension wall 384b, which is disposed on one side of the first lower extension wall 384a; and a third lower extension wall 384c, which is disposed on the other side of the first lower extension wall 384a.

[0283] The second lower extension wall 384b and the third lower extension wall 384c can be configured in opposite directions. The second lower extension wall 384b and the third lower extension wall 384c can be configured facing each other.

[0284] The lower end of the first lower extension wall 384a is formed below the upper end of the water level sensor cover 368. The lower ends of the second lower extension wall 384b and the third lower extension wall 384c are each formed above the upper end of the water level sensor cover 368. The water level sensor cover 368 can be disposed below the second lower extension wall 384b or the third lower extension wall 384c.

[0285] The lower end of the first lower extension wall 384a may be located lower than the lower end of the second lower extension wall 384b or the lower end of the third lower extension wall 384c. In the region opposite to the second connecting hole 311b, a hole may be formed between the second lower extension wall 384b and the third lower extension wall 384c to allow humidified air flowing in the second connecting hole 311b to flow into the exhaust pipe 382.

[0286] The humidifier water tank cover 380 can be integrally formed with the first upper cover 322.

[0287] The first connecting pipe 390 supplies water from the first humidifying water tank 300 to the second humidifying water tank 350. One side of the first connecting pipe 390 can be connected to the first humidifying water tank 300, and the other side can be connected to the second humidifying water tank 350. The first connecting pipe 390 can connect to the outlet hole 316 of the first humidifying water tank 300 and the inlet hole 358 of the second humidifying water tank 350. The first connecting pipe 390 can be configured to gradually decrease in elevation from the outlet hole 316 to the inlet hole 358.

[0288] The first connecting pipe 390 may extend along the circumferential periphery of the first humidifying water tank wall 302. The inlet hole 358 and the outlet hole 316 may be arranged in different directions. Therefore, the first connecting pipe 390 may have a structure that extends along the periphery of the first humidifying water tank wall 302.

[0289] The first connecting pipe 390 may be longer than the second connecting pipe 392. The first connecting pipe 390 may be equipped with a second valve 402. The second valve 402 may be configured to be closer to the first humidifying water tank 300 than the second humidifying water tank 350. The second valve 402 may be configured to be closer to the outlet port 316 than the inlet port 358.

[0290] The second connecting pipe 392 supplies water from the second humidifying water tank 350 to the first humidifying water tank 300. The second connecting pipe 392 is equipped with a pump 404. The second connecting pipe 392 connects the recovery discharge hole 360 ​​of the second humidifying water tank wall 352 and the recovery inflow hole 314 of the first humidifying water tank wall 302.

[0291] The recovery discharge port 360 can be located lower than the recovery inlet port 314. The pump 404 can be configured above the recovery discharge port 360 and the recovery inlet port 314.

[0292] The second connecting pipe 392 may include a pump inlet pipe 392a connecting the second humidifying water tank 350 and the pump 404, and a pump outlet pipe 392b connecting the pump 404 and the first humidifying water tank 300. The pump 404 may be configured on one side of the second humidifying water tank 350.

[0293] The humidifier includes a drain pipe 394 and a drain valve 396. The drain pipe 394 discharges water present in the first humidification water tank 300, and the drain valve 396 is located at the end of the drain pipe 394 to open and close the drain pipe 394. (Refer to...) Figure 11 The drain pipe 394 can be connected to one side of the first humidification water tank 300. The drain pipe valve 396 can be configured at the end of the drain pipe 394.

[0294] Drain pipe 394 can drain the water stored in the first humidification water tank 300 to the outside. (See reference...) Figure 10 The drain pipe 394 can extend to the outside of the humidification module cover 410.

[0295] Figure 14 This is a schematic diagram illustrating the specific connection relationship and internal configuration of the first humidifying water tank and the second humidifying water tank according to an embodiment of the present invention.

[0296] Reference Figure 14 This describes the various sensors and valves configured in the first humidification tank 300 and the second humidification tank 350, as well as the operation of the first humidification tank 300 and the second humidification tank 350.

[0297] The first humidifying water tank 300 heats the water supplied from the water tank 100. Water from the water tank 100 is supplied to the upper side of the first humidifying water tank 300. The first valve 400 opens the supply pipe 230, thereby supplying water to the first humidifying water tank 300.

[0298] The first valve 400 operates based on the water level detected by the first water level sensor 338. When the water level detected by the first water level sensor 338 is lower than the set water level, the first valve 400 can open the supply pipe 230. The set water level is the reference water level for opening and closing the supply pipe 230, and can also be called the water supply level or reference water level LV_A.

[0299] When the water level detected by the first water level sensor 338 is above the set water level, the first valve 400 closes the supply pipe 230. When the second valve 402 opens the first connecting pipe 390, the first valve 400 can close the supply pipe 230. Therefore, the water flowing through the first connecting pipe 390 can be water that has been heated in the first humidification water tank 300.

[0300] When the water quality detected by the sensor 234 is above the set standard, the first valve 400 opens the supply pipe 230. The sensor 234 can measure the water quality by measuring the water's conductivity. That is, it can measure the ion concentration by measuring the water's conductivity. Therefore, water whose quality has been improved by the water softener 140 can be supplied to the first humidification tank 300.

[0301] When the water supplied to the first humidifying water tank 300 reaches a constant level and the first valve 400 closes the supply pipe 230, the heater 340 can operate. The heater 340 heats the water stored in the first humidifying water tank 300. The humidified air generated by the operation of the heater 340 can flow to the second humidifying water tank 350 through the connecting pipe 310.

[0302] When the heater 340 is operating, the air supply fan 62 can also operate. That is, when the heater 340 heats the water stored in the first humidifying water tank 300, the air supply fan 62 operates and supplies air to the second humidifying water tank 350. The air supply fan 62 can supply air to the second humidifying water tank 350, thereby cooling the interior of the second humidifying water tank 350.

[0303] The heater 340 can operate until the water temperature detected by the first temperature sensor 336 reaches 100 degrees Celsius. Water stored in the first humidification tank 300 is heated to its boiling point for sterilization. When the water temperature detected by the first temperature sensor 336 reaches 100 degrees Celsius, the second valve 402 opens the first connecting pipe 390. The second valve 402 can also open the first connecting pipe 390 after the water temperature detected by the first temperature sensor 336 has reached 100 degrees Celsius.

[0304] The first temperature sensor 336 can be configured at the same height as or lower than the outlet orifice 316. Therefore, the temperature of the water remaining after the water from the second humidifying water tank 350 has been discharged through the first connecting pipe 390 can be detected.

[0305] When the second valve 402 is opened, the water stored in the first humidifying water tank 300 flows to the second humidifying water tank 350 due to gravity. When the second valve 402 is opened, the water will move until the water levels in the first humidifying water tank 300 and the second humidifying water tank 350 are the same. When the second valve 402 is opened, the water level in the first humidifying water tank 300 drops to the height of the outlet hole 316 formed in the first humidifying water tank 300.

[0306] When the second water level sensor 366 detects that the water level in the second humidification tank 350 is lower than the optimal height required for the vibrator 370 to operate, the second valve 402 opens the first connecting pipe 390. When the first water level sensor 338 and the second water level sensor 366 detect a water level difference between the first humidification tank 300 and the second humidification tank 350, the second valve 402 opens the first connecting pipe 390.

[0307] The second valve 402 can be opened during a set time period. That is, the time required for the water levels of the first humidifying water tank 300 and the second humidifying water tank 350 to become the same can be taken into account, causing the first connecting pipe 390 to open during the set time period and close after the set time has elapsed. The time it takes for water to flow from the first humidifying water tank 300 to the second humidifying water tank 350 can be taken into account, causing the second valve 402 to open during the set time period.

[0308] The air supply fan 62 can be operated while the second valve 402 is open. By operating the air supply fan 62, the air flowing into the second humidification tank 350 can cool the water flowing into the second humidification tank 350 through the first connecting pipe 390.

[0309] The second temperature sensor 364 detects the temperature of the water stored in the second humidification water tank 350. The second temperature sensor 364 can detect the temperature of the water flowing into the second humidification water tank 350 through the inlet 358. The vibrator 370 can operate when the water temperature detected by the second temperature sensor 364 is below a set temperature. The set temperature for the operation of the vibrator 370 can be set to prevent damage to the vibrator 370.

[0310] The second temperature sensor 364 can be configured at the same height as or below the inlet 358. Therefore, the temperature of the water flowing in through the inlet 358 can be detected.

[0311] The second water level sensor 366 can detect the water level in the second humidification tank 350. The second water level sensor 366 can detect the lowest water level in the second humidification tank 350 when the vibrator 370 is not operating. If the water level in the second humidification tank 350 detected by the second water level sensor 366 is lower than a set water level, the vibrator 370 can stop operating. The lowest water level at which the vibrator 370 stops operating can be determined based on the water level stored in the second humidification tank 350 compared to the vibration level of the vibrator 370.

[0312] The second water level sensor 366 can detect the optimal water level for the vibrator 370 to operate. The second water level sensor 366 can detect the upper and lower water levels at which the vibrator 370 can operate optimally when the water level in the second humidification tank 350 is higher than the lowest water level at which the vibrator 370 stops operating.

[0313] The second water level sensor 366 can be a sensor that detects multiple levels. For example, the second water level sensor 366 can be a three-channel sensor 366a, 366b, and 366c capable of detecting three levels of water level LV_1, LV_2, and LV_3. The first channel 366a can detect the first water level LV_1. The first water level LV_1 can be the lowest water level that the second water level sensor 366 can detect.

[0314] The second channel 366b can detect the second water level LV_2, and the third channel 366c can detect the third water level LV_3. The second water level LV_2 can be a water level higher than the first water level LV_1, and the third water level LV_3 can be a water level higher than the second water level LV_2.

[0315] The first water level LV_1 can be the lowest water level. The second water level LV_2 and the third water level LV_3 can be the management water level range corresponding to the vibrator 370. The second water level LV_2 can be the lower limit of the management water level range, and the third water level LV_3 is the upper limit of the management water level range.

[0316] In the second humidification tank 350, a water level sensor cover 368 is disposed between the second water level sensor 366 and the vibrator 370, so that water level detection can be stably performed even when the vibrator 370 is running.

[0317] When the water level detected by the second water level sensor 366 is above the set water level, the vibrator 370 can operate. The vibrator 370 may include two vibrating elements 372. Therefore, the two vibrating elements 372 can operate independently. The two vibrating elements 372 can operate selectively.

[0318] When the vibrator 370 is running, the air supply fan 62 can also operate. Therefore, the humidified air generated by the vibrator 370 can be discharged to the outside of the humidifier along with the air flowing from the second humidification tank 350 to the first discharge path 32 via the air supply fan 62. The air supply fan 62 can promote the flow of the humidified air generated by the vibrator 370.

[0319] The vibrator 370 and the heater 340 can operate simultaneously. At this time, the humidified air generated in the first humidification tank 300 flows to the first discharge path 32 through the second humidification tank 350, and the humidified air generated in the second humidification tank 350 also flows to the first discharge path 32.

[0320] Pump 404 directs water from the second humidifying tank 350 to the first humidifying tank 300. Pump 404 can operate after vibrator 370 stops. Pump 404 can operate after second valve 402 closes first connecting pipe 390. When pump 404 is running, first valve 400 can close supply pipe 230. When pump 404 is running, blower fan 62 can stop operating.

[0321] A recovery discharge port 360 can be formed on one side of the height where the vibrator 370 is located. The recovery discharge port 360 is positioned lower than the inlet port 358 formed in the second humidification tank 350. The pump 404 is positioned higher than the locations where the recovery discharge port 360 and the recovery inlet port 314 are formed. Therefore, water can be drawn from the wall 352 of the second humidification tank and supplied to the first humidification tank 300.

[0322] Pump 404 can operate based on the water level of the first humidification tank 300 detected by the first water level sensor 338 and the water level of the second humidification tank 350 detected by the second water level sensor 366. Operation of pump 404 can be prevented if the water level in the first humidification tank 300 is above a suitable level.

[0323] Water stored in the first humidifying water tank 300 can be discharged to the outside through the drain pipe 394. When the drain pipe valve 396 opens the drain pipe 394, water stored in the first humidifying water tank 300 can be discharged to the outside. The drain hole 318 formed in the first humidifying water tank 300 can be configured at the location where the heater 340 is configured. Water stored between the heater 340 and the first humidifying water tank 300 can flow to the drain pipe 394 through the drain hole 318.

[0324] Figure 15 This is a block diagram of a humidifier according to an embodiment of the present invention.

[0325] Reference Figure 15 According to one embodiment of the present invention, a humidifier may include a control unit 1540 for controlling the overall operation of the humidifier in order to provide humidification and / or air purification functions.

[0326] Figure 15 At least a portion of the internal modules of the humidifier, such as the control unit 1540 in the example, can be configured inside the housing 10. For example, the control unit 1540 can be mounted on a circuit board 76 configured in the control box 74.

[0327] Inside the housing 10 is a blower 62 for controlling the direction of the airflow after it is purified by the filter 50 and then discharged.

[0328] The control unit 1540 can control the rotational speed (RPM) of the air supply fan 62 according to the operating mode. The fan drive unit 1580 drives the air supply fan 62 according to the control of the control unit 1540.

[0329] The fan motor 64 rotates the air supply fan 62 according to the control signal received from the fan drive unit 1580. The rotation of the air supply fan 62 is regulated by the fan drive unit 1580, and the operation of the fan drive unit 1580 is controlled by the control unit 1540. The fan drive unit 1580 may have a power conversion device such as an inverter to enable the fan motor 64 to operate.

[0330] The humidifier includes a heater 340, a vibrator 370, and a valve 1560. The control unit 1540 can control the heater 340, the vibrator 370, and the valve 1560.

[0331] For example, valve section 1560 includes a first valve 400 and a second valve 402. The first valve 400 is disposed on a supply pipe 230 connecting the water tank 100 and the first humidifying water tank 300. The second valve 402 connects the first humidifying water tank 300 and the second humidifying water tank 350 and opens and closes the first connecting pipe 390.

[0332] When the water level detected by the first water level sensor 338 is lower than the reference water level LV_A, the control unit 1540 can open the supply pipe 230. The control unit 1540 controls the first valve 400 to be in the open state, thereby opening the supply pipe 230.

[0333] When the supply pipe 230 is opened, water is supplied from the water tank 100 to the first humidifying water tank 300. The control unit 1540 activates the heater 340, thereby heating the water in the first chamber 300a. The heater 340 heats the water formed in the first chamber 300a of the first humidifying water tank 300.

[0334] The control unit 1540 can control the second valve 402 based on the water level detected by the second water level sensor 366.

[0335] The second water level LV_2 can be the low water level at the start of water supply, and the third water level LV_3 can be the full water level at the end of water supply. The first water level LV_1 can be the empty water level when operation stops.

[0336] The control unit 1540 controls the second valve 402 to be in the open state, thereby opening the first connecting pipe 390. When the first connecting pipe 390 is opened, the water heated in the first humidifying water tank 300 by the operation of the heater 340 flows to the second humidifying water tank 350.

[0337] On the other hand, the first humidifying water tank 300 and the second humidifying water tank 350 are connected by a connecting pipe 310. The steam generated in the first humidifying water tank 300 by the operation of the heater 340 flows to the second humidifying water tank 350 through the connecting pipe 310.

[0338] The control unit 1540 activates the vibrator 370 according to an operating mode that includes a humidification function. The control unit 1540 can control the duty cycle of the vibrator 370 according to the operating mode. The control unit 1540 can activate the vibrator 370 to generate humidified air.

[0339] An air supply port 387 is formed in the second humidifying water tank 350 to supply air flowing through the blower fan 62 to the second chamber 350a. An exhaust port 382a is formed in the second humidifying water tank 350 to discharge the humidified air generated in the second chamber 350a to the outside. An exhaust pipe 382 delivers the humidified air generated in the second humidifying water tank 350 to the first discharge flow path 32. The exhaust port 382a is formed at the lower end of the exhaust pipe 382.

[0340] The humidified air discharged from the second humidification tank 350 can flow to the first discharge path 32. On the other hand, the air filtered in the filter 50 can flow to the second discharge path 34. The air flowing in the first discharge path 32 and the air flowing in the second discharge path 34 can be mixed in the mixing path 13.

[0341] The control unit 1540 can operate the heater 340 according to the operating mode. The operating modes that include humidification function can include a mode in which the heater 340 is driven according to conditions and a mode in which the heater 340 is continuously driven.

[0342] The control unit 1540 can control the duty cycle of the heater 340 according to the operating mode. In addition, the control unit 1540 can control the output of the heater 340 according to the operating mode.

[0343] The control unit 1540 can control the humidifier according to the humidification amount set for each operating mode. In addition, the control unit 1540 can control the air supply fan 62, heater 340, and vibrator 370 based on the humidification amount.

[0344] When the humidification operation ends, the control unit 1540 can activate the pump 404 to recover the residual water.

[0345] On the other hand, the humidifier includes a memory 1530, a detection unit 1550, a communication unit 1570, etc.

[0346] The memory 1530 can store data used to control the operation of the humidifier, data detected or measured by the detection unit 1550 during operation, and data received by the communication unit 1570. On the other hand, the humidifier may include a buffer for temporary data storage, which may be included in the control unit 1540 or the memory 1530.

[0347] The control unit 1540 can process various data received through the communication unit 1570, thereby updating the memory 1530. For example, if the data input through the communication unit 1570 is update data for the running program pre-stored in the memory 1530, the memory 1530 can be updated using this data; if the input data is a new running program, it can be appended to the memory 1530.

[0348] The detection unit 1550 includes one or more sensors that can measure water temperature, water level, humidity, etc., or detect the operating status of the humidifier.

[0349] For example, the detection unit 1550 may include: a first water level sensor 338, which detects the water level stored in the first humidification water tank 300; a first temperature sensor 336, which detects the temperature of the water stored in the first humidification water tank 300; a second water level sensor 366, which detects the water level stored in the second humidification water tank 350; and a second temperature sensor 364, which detects the temperature of the water stored in the second humidification water tank 350.

[0350] For example, the detection unit 1550 may include a humidity sensor (not shown).

[0351] The control unit 1540 can drive the vibrator 370 based on the water level detected by the water level sensors 338 and 366, the humidity of the indoor space detected by the humidity sensor, the user-set desired humidity, the amount of fog, and the operating mode.

[0352] The control unit 1540 can control the data stream input to or output to the humidifier, and generate and apply control commands based on the data input from the detection unit 1550.

[0353] On the other hand, the humidifier can establish communication connections with other devices such as servers, home appliances, and terminals through the communication unit 1570 to send and receive data.

[0354] The input unit 1510 can receive various user commands related to the operation of the humidifier and transmit control signals corresponding to the input commands to the control unit 1540. The input unit 1510 may include a touchpad, physical buttons, etc.

[0355] The output unit 1520 may include a display device such as a display 30 or a light-emitting diode (LED) (not shown). For example, the output unit 1520 may display the humidifier's operating status, error occurrence and other related operating statuses, or information such as indoor temperature and target temperature.

[0356] The output unit 1520 may include audio devices such as a speaker (not shown) and a buzzer (not shown). For example, the output unit 1520 may output sound effects related to the operating status of the humidifier and output a warning sound when an error occurs.

[0357] The control unit 1540 can be connected to each component of the humidifier. For example, the control unit 1540 can send and / or receive signals to each component of the humidifier, thereby controlling the overall operation of each component.

[0358] The control unit 1540 may include at least one processor and can use the included processor to control the overall operation of the humidifier. The processor may be a general-purpose processor such as a CPU (central processing unit). Alternatively, the processor may be a dedicated device such as an ASIC or other hardware-based processor.

[0359] On the other hand, the control unit 1540 can control the overall operation of the humidifier, including humidification, air purification, and various sterilization functions.

[0360] The humidifier can provide multiple operating modes. For example, it can provide a humidification operating mode with humidification function, an air purification mode with air purification function, and a humidification and purification mode that has both humidification and air purification functions. In addition, the humidification operating mode can include a warm humidification mode that continuously drives the heater 340 and a pure humidification mode that drives the heater 340 according to conditions.

[0361] In this manual, the humidification operation provides humidification functions, which may include humidification operation mode, humidification purification mode, warm humidification mode, and pure humidification mode.

[0362] On the other hand, each operating mode may include a plurality of operating steps with different control options for the air supply fan 62, heater 340, and vibrator 370. For example, the plurality of operating steps may include sleep, weak, medium, strong, and turbine operating steps in order of operating intensity.

[0363] Furthermore, the control unit 1540 can determine whether the water tank 100 is installed and the water level based on the data detected by the weight sensors 212a and 212b, and can control the humidifier's operation, such as humidification. Additionally, since the absence of the water tank 100 is not a normal situation, emergency control is required if the water tank 100 is not detected during operation.

[0364] Figure 16 This is a flowchart illustrating an operation method of a humidifier according to an embodiment of the present invention, disclosing emergency control logic based on data detected by a weight sensor.

[0365] Reference Figure 16 The control unit 1540 processes the data detected by the weight sensors 212a and 212b (S1610).

[0366] The weight value used in the control logic can be a value based on data detected by weight sensors 212a and 212b. For example, weight sensors 212a and 212b can be load cells, and the weight value can be the load cell value output by the load cells. Alternatively, the weight value can be a value obtained by processing (e.g., averaging) the load cell values.

[0367] The control unit 1540 can control the humidifier based on the weight value determined by processing the data detected by the weight sensors 212a and 212b.

[0368] Weight sensors 212a and 212b can be configured in the intermediate tray 200. In addition, a lamp 216 that illuminates the first discharge flow path 32 can be configured in the intermediate tray 200.

[0369] On the other hand, weight sensors 212a and 212b can be connected to sensor circuit board 228. According to an embodiment, sensor circuit board 228 can process the data detected by weight sensors 212a and 212b. Sensor circuit board 228 can transmit the determined weight value to control unit 1540. Control unit 1540 can control the humidifier based on the transmitted weight value.

[0370] That is, the data detected by the weight sensors 212a and 212b can be processed by the control unit 1540 or the sensor circuit board 228. The following explanation will use the case where the control unit 1540 processes the data detected by the weight sensors 212a and 212b as an example, but the sensor circuit board 228 can also process the data in the same way.

[0371] Figure 17 This is a reference diagram illustrating the data processing of a weight sensor according to an embodiment of the present invention.

[0372] Reference Figure 17 The weight sensors 212a and 212b, which are configured on the lower side of the water tank 100 and the inner shell 180, can acquire data in the first cycle T1.

[0373] Alternatively, weight sensors 212a and 212b can acquire data in real time and sample it in the first period T1.

[0374] According to the embodiment, the weight sensors 212a and 212b can communicate with the control unit 1540 in real time. The control unit 1540 can sample the data received from the weight sensors 212a and 212b in a first period T1 to obtain the data.

[0375] Figure 17 The example illustrates 10 data points (D1 to D10) acquired during the first cycle T1 of 10. For instance, if the first cycle T1 is 0.2 seconds, then 10 data points (D1, D2, D3, D4, D5, D6, D7, D8, D9, D10) are acquired every 0.2 seconds from weight sensors 212a and 212b during a 2-second period.

[0376] The control unit 1540 can process the data (D1 to D10) detected by the weight sensors 212a and 212b. The control unit 1540 can determine each data (D1 to D10) as a weight value used in the control logic.

[0377] However, in order to acquire a large amount of data and accurately control the humidifier, if the first cycle T1 is set too short, the amount of data that needs to be processed will be too large, resulting in low data processing and control efficiency.

[0378] Therefore, in order to acquire a large amount of data and accurately control the humidifier while effectively processing the data, the control unit 1540 can process the data (D1 to D10) and calculate the weight value of the secondary processing.

[0379] The control unit 1540 can calculate the weight value by averaging the data (D1 to D10). More preferably, the control unit 1540 can calculate the weight value over a second period T2. Here, the second period T2, which is the average calculation period, is set to be longer than the first period T1, which is the data acquisition period.

[0380] The control unit 1540 can calculate the weight value by averaging the prescribed data every second cycle T2. Additionally, the control unit 1540 can calculate the weight value by averaging the data during a third cycle T3 every second cycle T2. The third cycle T3 is set to be longer than the second cycle T2, thereby allowing more data to be used for averaging calculations.

[0381] Therefore, while improving data processing efficiency, continuous weight value calculation can accurately monitor data changes.

[0382] exist Figure 17 In the example, the control unit 1540 can average D1, D2, D3, D4, and D5 to calculate the weight value. After the second cycle T2, D3, D4, D5, D6, and D7 can be averaged to calculate the next weight value. Again, after the second cycle T2, D5, D6, D7, D8, and D9 can be averaged to calculate the next weight value. In this way, the weight value is continuously calculated by averaging the data during the third cycle T3 every second cycle T2.

[0383] On the other hand, the control unit 1540 excludes zeros from the averaging calculation in the data during the third period T3. Furthermore, if the data includes a reference number (e.g., 5) or more consecutive zeros, the control unit 1540 can treat the weight value as zero. Therefore, even if any single "0" exists, it will not affect the average value; as long as it does not become N consecutive "0"s, it will not be identified as "0". Thus, noise in the data can be removed, preventing erroneous operation.

[0384] On the other hand, if the weight value increases (S1620), the control unit 1540 can determine that water is being supplied to the water tank 100 (S1630). To further improve accuracy, the control unit 1540 can determine that water is being supplied when the weight value increases twice or more consecutively.

[0385] On the other hand, if the weight value is below the first reference value (S1640), the control unit 1540 shuts off the vibrator 370 and the heater 340 (S1650).

[0386] The first reference value can be set based on the state where the water tank 100 is removed. If the weight value is below the first reference value, the control unit 1540 can determine that the water tank 100 is not installed.

[0387] For example, during humidification operation, the user can detach the water tank 100 from the humidifier to refill the water tank 100 or simply clean it before use. In this case, the vibrator 370 and heater 340 can be turned off to prevent unnecessary humidification operation and safety accidents.

[0388] The control unit 1540 can turn off the vibrator 370 and the heater 340 while keeping the air supply fan 62 running. By keeping the air supply fan 62 running, the humidifier can operate in air purification mode.

[0389] On the other hand, lamp 216 can also remain in operation, intuitively displaying the current status.

[0390] If the control unit 1540 determines that the weight value exceeds the first reference value again due to the installation of the water tank 100, it can turn on the vibrator 370 and the heater 340 to quickly return to the humidification operation mode.

[0391] Therefore, users can conveniently supply water or clean the sink 100 while it is in operation, which improves convenience.

[0392] On the other hand, if the weight value is below the second reference value which is lower than the first reference value (S1660), the control unit 1540 can not only turn off the vibrator 370 and the heater 340, but also turn off the lamp 216 (S1670).

[0393] The second reference value can be set based on the state where the water tank 100 and the inner shell 180 are removed. If the weight value is below the second reference value, the control unit 1540 can determine that the water tank 100 and the inner shell 180 are not installed.

[0394] The inner shell 180 can form the inner water tank 100 and the first discharge flow path 32. Additionally, the inner shell 180 can form the outer shell 22 and the second discharge flow path 34. At least a portion of the inner shell 180 is formed of a transparent material, allowing light from the lamp 216 to pass through.

[0395] Figure 18 This is a reference diagram for a description of a water tank inspection according to an embodiment of the present invention, illustrating the steps for determining whether an installation has been completed based on a weight value.

[0396] Reference Figure 18 If the weight value exceeds the first reference value (e.g., 1500), it means that both the sink 100 and the inner shell 180 are installed.

[0397] If the weight value exceeds the second reference value (e.g., 300) and is less than the first reference value (e.g., 1500), it indicates that the inner shell 180 is installed and only the sink 100 is not installed.

[0398] If the weight value is below the second reference value (e.g., 300), it means that neither the sink 100 nor the inner shell 180 is installed.

[0399] If not only the water tank 100 but also the inner casing 180 is removed, the light 216 may be exposed to the outside. If the inner casing 180 is also removed, humidification operation can be stopped, the light 216 can be turned off, and the current status can be clearly displayed.

[0400] Based on the data detected by the weight sensors 212a and 212b, the control unit 1540 determines whether the water tank 100 and the inner shell 180 are installed, and controls the operation appropriately according to the determined state, which can improve convenience and reliability.

[0401] According to the present invention, the air purification mode can be used without turning off the humidifier product, the water tank 100 can be easily cleaned and immediately reinstalled for reuse, thus improving ease of use.

[0402] Figure 19 This is a flowchart illustrating the operation method of a humidifier according to an embodiment of the present invention.

[0403] During humidification operation, the control unit 1540 can open the first valve 400 to supply water from the water tank 100 to the first humidification water tank 300 (S1910).

[0404] However, if even if the first valve 400 is opened (S1910) and a reference time has elapsed (S1920), the first water level sensor 338 still does not detect the reference water level level LV_A (S1930), the control unit 1540 executes water shortage notification control (S1940).

[0405] During water shortage notification control (S1940), the output unit 1520 can continuously display a water replenishment screen. Additionally, during water shortage notification control (S1940), the output unit 1520 can output a water shortage melody a predetermined number of times.

[0406] On the other hand, during water shortage notification control (S1940), when the heater 340 and vibrator 370 are in operation, the control unit 1540 shuts down or restricts the operation of the heater 340 and vibrator 370.

[0407] Figure 20 This is a flowchart illustrating the operation method of a humidifier according to an embodiment of the present invention, disclosing the storage mode logic.

[0408] Reference Figure 20 In the operation stopped state (S2010), the control unit 1540 processes the data detected by the weight sensors 212a and 212b (S2010).

[0409] Reference Figure 16 and Figure 17 The control unit 1540 can calculate the weight value by processing the data detected by the weight sensors 212a and 212b.

[0410] Furthermore, according to the embodiment, the sensor circuit board 228 can process the data detected by the weight sensors 212a and 212b. The sensor circuit board 228 is able to transmit the determined weight value to the control unit 1540.

[0411] The control unit 1540 can calculate the weight value by averaging the data during the third period T3 every second period T2. The data can be acquired in the first period T1.

[0412] The control unit 1540 can exclude zeros from the averaging calculation in the data during the third period T3. In addition, if the data includes more than a base number (e.g., 5) of consecutive zeros, the control unit 1540 can treat the weight value as zero.

[0413] In the stopped state, if the weight value is below the first reference value (S2030), the control unit 1540 controls the opening of the first valve 400 (S2040).

[0414] If the first valve 400 is closed during water inflow, water may still accumulate around the first valve 400 after the humidification operation ends. Before the water supplied through the softening device 140 is delivered into the first humidification tank 300, residual water may be generated near the first valve 400 as the first valve 400 is closed.

[0415] The first reference value can be set based on the state where the sink 100 is removed. If the weight value is below the first reference value, the control unit 1540 can determine that the sink 100 is not installed.

[0416] In this case, the control unit 1540 can control the opening of the first valve 400 (S2040) so that the residual water around the first valve 400 flows to the first humidification water tank 300.

[0417] In addition, with the first valve 400 open, the control unit 1540 can control the air supply fan 62 to rotate, thereby drying the interior faster.

[0418] In addition, during long-term storage, the user can open the drain pipe 394 through the drain pipe valve 396 to drain the water from the first humidification water tank 300 to the outside.

[0419] The control unit 1540 can open the first valve 400 and then close it after a preset opening time. The first valve 400 can be closed after the opening time has elapsed. The air supply fan 62 can rotate during the opening time and stop once the opening time has elapsed.

[0420] On the other hand, the opening of the first valve 400 used for storage can be limited to once.

[0421] Therefore, the control unit 1540 can count the number of times the first valve 400 is opened (S2040).

[0422] On the other hand, if humidification operation is performed (S2060), the control unit 1540 can initialize the number of times it is turned on (S2070).

[0423] As humidification operation is performed, if the first valve 400 opens and then closes (S2060), the control unit 1540 can initialize the number of openings (S2070).

[0424] The control unit 1540 can activate the first valve 400 based on the data from the weight sensors 212a and 212b in the stopped state, thereby enhancing internal hygiene and enabling the humidifier to be stored in a clean state when not in use.

[0425] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and those skilled in the art to which this invention pertains can make various modifications without departing from the spirit of the invention as claimed in the claims.
