Description

[0001] This application is a divisional application of an application filed on October 28, 2016, with application number 201610997363.6 and invention name “Humidification and Purification Device”. Technical Field

[0002] The invention relates to a humidifying and purifying device. Background Art

[0003] Air conditioning devices include air conditioners for controlling the temperature of air, air purifiers for removing impurities from the air to maintain its purity, humidifiers for adding moisture to the air, and dehumidifiers for removing moisture from the air.

[0004] Conventional humidifiers are divided into two types: a vibration-type humidifier in which water is atomized on a vibration plate and discharged into the air; and a natural evaporation-type humidifier in which water evaporates naturally on a humidification filter.

[0005] The natural evaporation humidifier is divided into: a disk-type humidifier in which a driving force is used to rotate a disk, and water evaporates naturally on the disk surface in the air; and a humidification filter-type humidifier in which water evaporates naturally due to the flowing air in a humidifying medium soaked in water.

[0006] During the humidification process of the existing humidifier, a portion of the flowing air is filtered in the filter.

[0007] However, the existing humidifier is only used in the season with low humidity, and the air purifier does not have a humidification function, so there is a problem that two products need to be equipped.

[0008] Furthermore, the existing humidifier has a humidification function as its main function, and an air purification function for purifying the air as its additional function, so there is a problem that the air purification function is relatively weak.

[0009] Furthermore, conventional humidifiers or air purifiers cannot distinguish between humidification and air purification and operate them independently. Summary of the Invention

[0013] An object of the present invention is to provide a humidification and purification device capable of creating a rain scene by scattering a portion of water supplied for watering.

[0014] An object of the present invention is to provide a humidifying and purifying device that can reproduce a rain scene by re-scattering a portion of the sprayed water by rotating watering wings during watering.

[0088] The advantages, features, and methods for achieving the same will become more apparent with reference to the accompanying drawings and the embodiments described in detail below. However, the present invention is not limited to the embodiments disclosed below and can be implemented in a variety of forms. These embodiments are intended only to more fully disclose the present invention and to more fully indicate the scope of the present invention to those skilled in the art. The present invention is defined solely by the scope of the claims. Throughout this specification, the same reference numerals denote the same structural elements.

[0089] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0090] Figure 1 is a perspective view of a humidifying and purifying device according to a first embodiment of the present invention. Figure 2 yes Figure 1 Exploded perspective diagram, Figure 3 yes Figure 1 Exploded main view of Figure 4 It is along Figure 3 The cross-sectional view taken along line BB of Figure 5Schematic diagram showing the air flow of the humidification and purification device according to the first embodiment of the present invention.

[0091] The humidification and purification device of this embodiment includes: an air cleaning module 100 (air clean module); and an air washing module 200 (air wash module) placed on the upper side of the air cleaning module 100.

[0092] The air cleaning module 100 inhales external air, filters it, and provides the filtered air to the air washing module 200. The air washing module 200 receives the filtered air, humidifies it to provide moisture, and discharges the humidified air to the outside.

[0093] The air cleaning module 200 includes a water tank 300 for storing water. When the air cleaning module 200 is separated, the water tank 300 can be separated from the air cleaning module 100. The air cleaning module 200 is placed above the air cleaning module 100.

[0094] The user can separate the air cleaning module 200 from the air cleaning module 100 and clean the separated air cleaning module 200. The user can clean the interior of the air cleaning module 100 after the air cleaning module 200 is separated. When the air cleaning module 200 is separated, the top of the air cleaning module 100 is open to the user.

[0095] The air cleaning module 100 includes a filter assembly 10 described below. The filter assembly 10 can be separated from the base 110 and cleaned.

[0096] A user may supply water to the air cleaning module 200. A water supply passage 109 is formed in the air cleaning module 200 so that water can be supplied to the water tank 300 from the outside.

[0097] The water supply flow path 109 is configured to be separated from the discharge flow path 107 for discharging air. The water supply flow path 109 is configured to supply water to the water tank at any time. For example, when the air cleaning module 200 is in operation, water can also be supplied through the water supply flow path. For example, when the air cleaning module 200 is combined with the air cleaning module 100, water can also be supplied through the water supply flow path. For example, when the air cleaning module 200 is separated from the air cleaning module 100, water can also be supplied through the water supply flow path.

[0098] The air cleaning module 100 and the air cleaning module 200 are connected via a connecting flow path 103. Since the air cleaning module 200 is detachably provided, the connecting flow path 103 is dispersed between the air cleaning module 100 and the air cleaning module 200. Only when the air cleaning module 200 is placed on the air cleaning module 100 can the flow path of the air cleaning module 200 and the flow path of the air cleaning module 100 be connected to each other via the connecting flow path 103.

[0099] The connecting flow path formed in the air cleaning module 100 is defined as a cleaning connecting flow path 104 , and the connecting flow path formed in the air cleaning module 200 is defined as a humidifying connecting flow path 105 .

[0100] The flow of air passing through the air cleaning module 100 and the air washing module 200 will be described in detail later.

[0101] Hereinafter, the air cleaning module 100 and the air cleaning module 200 will be described in more detail.

[0102] The air cleaning module 100 includes: a base 110; a filter assembly 10 disposed on the base 110 for filtering air; and an air supply unit 20 disposed on the base 110 for flowing air.

[0103] The air cleaning module 200 includes: a water tank 300, which stores water for humidification and is detachably placed in the air cleaning module 100; a watering unit 400, which is arranged inside the water tank 300 and sprays water from the water tank; a humidifying medium 50, which is soaked with water sprayed by the watering unit 400 and provides moisture to the flowing air; a visual body 210, which is combined with the water tank 300 and is formed of a material that allows the interior to be seen; and a top cover assembly 230, which is detachably placed in the visual body 210 and is formed with an exhaust flow path 107 for exhaling air and a water supply flow path 109 for supplying water.

[0104] The air cleaning module 100 is provided with an intake passage 101 , a filter passage 102 , a blower passage 108 , and a clean connecting passage 104 . Air drawn in through the intake passage 101 flows through the filter passage 102 and the blower passage 108 to the clean connecting passage 104 .

[0105] The air cleaning module 200 is provided with a humidification connection flow path 105 , a humidification flow path 106 , a discharge flow path 107 , and a water supply flow path 109 .

[0106] The cleaning connection flow path 104 of the air cleaning module 100 and the humidification connection flow path 105 of the air cleaning module 200 are connected only when the air cleaning module 200 is placed on the air cleaning module 100 .

[0107] The filtered air supplied through the humidification connection flow path 105 of the air cleaning module 200 is discharged into the room via the humidification flow path 106 and the discharge flow path 107. The water supply flow path 109 is structured to communicate with the humidification flow path 106, but does not discharge air but only receives water.

[0108] First, each structure of the air cleaning module 100 will be described.

[0109] The base body 110 is composed of an upper body 120 and a lower body 130. The upper body 120 is stacked on the lower body 130, and the upper body 120 and the lower body 130 are assembled.

[0110] Air flows into the interior of the base 110 .

[0111] The lower body 130 is provided with a suction flow path 101 , a filter flow path 102 , and an air supply flow path 108 , and also includes structures for forming the suction flow path 101 , the filter flow path 102 , and the air supply flow path 108 .

[0112] The upper body 120 is provided with a portion of the connecting flow path 103 , a structure for guiding filtered air to the air cleaning module 200 , and a structure for placing the air cleaning module 200 .

[0113] The base 110 includes a lower body 130 for forming an outer shape and having a suction port 111 formed on a lower side thereof; and an upper body 120 for forming an outer shape and combined with an upper side of the lower body 130 .

[0114] The filter assembly 10 is assembled to the base 110 in a detachable manner.

[0115] The filter assembly 10 provides a filter flow path 102 and filters external air. The filter assembly 10 has a structure that can be installed and removed in the horizontal direction relative to the base 110. The filter assembly 10 is arranged in a manner that intersects the flow direction of air flowing upstream in the vertical direction. The filter assembly 10 slides in the horizontal direction and filters air flowing upward in the vertical direction. The filter assembly 10 is arranged in a horizontal manner to form a filter flow path 102 in the vertical direction.

[0116] The filter assembly 10 can slide horizontally relative to the base 110 .

[0117] The filter assembly 10 includes a filter housing 12 disposed inside the lower body 130 to form a filter flow path 102 ; and a filter 14 detachably coupled to the filter housing 12 to filter air passing through the filter flow path 102 .

[0118] The filter housing 12 is connected to the suction flow path 101 at its lower side and to the air supply flow path 108 at its upper side. Air drawn in through the suction flow path 101 flows toward the air supply flow path 108 via the filter flow path 102 .

[0119] One side of the filter housing 12 is open in a direction intersecting the filter flow path 102. The filter 14 can be detachably coupled to the open surface of the filter housing 12. The open surface of the filter housing 12 is formed to face sideways. The open surface of the filter housing 12 is arranged on the outer side of the lower body 130. Thus, the filter 14 is inserted through the side of the lower body 130 and is located inside the filter housing 12. The filter 14 is arranged to intersect the filter flow path 102 and filters the air passing through the filter flow path 102.

[0120] The filter 14 may be an electrostatic dust filter that collects impurities in the air by charging an applied power source. The filter 14 may be formed of a material that collects impurities in the air through a filtering component. The filter 14 may have various configurations. The scope of protection of the present invention is not limited by the filtering method of the filter 14 or the filter component of the filter.

[0121] The filter flow path 102 is arranged in the same direction as the main flow direction of the humidification and purification device. In this embodiment, the filter flow path 102 is arranged in the vertical direction and causes air to flow in the direction opposite to gravity. That is, the main flow direction of the humidification and purification device is formed from the bottom to the top.

[0122] An air supply unit 20 is disposed on the upper side of the filter housing 12 .

[0123] The upper side of the filter housing 12 is formed in an open state, and the air passing through the filter flow path 102 flows toward the air supply unit 20 .

[0124] The air supply unit 20 generates air flow. The air supply unit 20 is disposed inside the base 110 and allows air to flow from the bottom to the top.

[0125] The air supply unit 20 comprises a fan housing 150, an air supply motor 22, and an air supply fan 24. In this embodiment, the air supply motor 22 is located on the upper side, and the air supply fan 24 is located on the lower side. The motor shaft of the air supply motor 22 is positioned downward, and the air supply fan 24 is assembled.

[0126] The blower fan housing 150 is disposed inside the base 110. The blower fan housing 150 provides a flow path for flowing air. The blower motor 22 and the blower fan 24 are disposed in the blower fan housing 150.

[0127] The blower fan housing 150 is disposed on the upper side of the filter assembly 10 and on the lower side of the upper body 120 .

[0128] The blower fan housing 150 defines an air flow path 108 therein. The blower fan 24 is disposed in the air flow path 108. The air flow path 108 connects the filter flow path 102 and the clean connection flow path 104.

[0129] The blower fan 24 is a centrifugal fan that sucks air from the bottom and then blows it outward in the radial direction. The blower fan 24 blows air outward and upward in the radial direction. The outer end of the blower fan 24 is formed to face radially upward.

[0130] To minimize contact with flowing air, the blower motor 22 is positioned above the blower fan 24. The blower motor 22 is positioned so as to be covered by the blower fan 24. The blower motor 22 is not located in the air flow path of the blower fan 24 and does not create resistance to the air flowing from the blower fan 24.

[0131] The upper body 120 includes: an upper outer body 128 (upper outer body), which is used to form the outer shape of the base 110 and is combined with the lower body 130; an upper inner body 140 (upper inner body), which is arranged on the inner side of the upper outer body 128, and the water tank 300 is inserted into the upper inner body 140, and the upper inner body 140 provides a connecting flow path 103; an air guide 170 (air guide), which combines the upper inner body 140 and the upper outer body 128 and is used to guide air to the water tank 300.

[0132] Since the upper body 120 separates the connecting flow path from the water tank insertion space, it is possible to minimize the flow of water from the water tank 300 into the connecting flow path. In particular, since the upper inner body divides the space, the connecting flow path is located outside the water storage space, which can prevent water from flowing into the connecting flow path.

[0133] The upper side of the upper inner body 140 is formed in an open state, and the water tank 300 is inserted into the upper inner body 140. The upper inner body 140 forms a part of the clean connection flow path 104 through which filtered air flows.

[0134] The upper inner body 140 is formed with an upper inlet 121 corresponding to the air cleaning inlet 31. The upper inlet 121 is not an essential component. As long as the upper body 120 exposes the air cleaning inlet 31 to the connecting flow path 103, it is sufficient.

[0135] The air guide 170 guides air supplied through the clean connecting flow path 104 toward the upper inlet 121. The air guide 170 collects air rising along the outer side of the base 110 and directs it inward. The air guide 170 redirects air flowing from the lower side to the upper side. However, when redirecting the air flow, the air guide 170 minimizes its angle to minimize air flow resistance.

[0136] The air guide 170 is formed to cover the outer side of the upper inner body 140 360 degrees. The air guide 170 guides air 360 degrees toward the water tank 300. The air guide 170 collects air guided along the outer side of the lower body 130 inward and supplies the air to the water tank 300. This structure ensures a sufficient flow rate of air supplied to the water tank 300.

[0137] Therefore, the air guide 170 includes a guide portion 172 formed along the flow direction of air, and a conversion portion 174 connected to the guide portion 172 to convert the flow direction of the guided air.

[0138] The air guide 170 forms the connecting flow path 103 .

[0139] The guide portion 172 is formed in a direction substantially the same as the filter flow path 102. In this embodiment, the guide portion 172 is formed in a vertical direction. The conversion portion 174 is formed in a direction intersecting the filter flow path 102. In this embodiment, the conversion portion 174 is formed in a substantially horizontal direction.

[0140] The conversion portion 174 is formed on the upper side of the air guide 170. The conversion portion 174 is preferably connected to the guide portion 172 through a curved surface structure.

[0141] Even if the conversion portion 174 is formed in a horizontal direction, the air passing through the connecting flow path 103 will flow in a substantially inclined upward direction. By forming the connection angle between the connecting flow path 103 and the filter flow path 102 to be close to the straight-forward direction, the flow resistance of the air can be reduced.

[0142] The lower end of the guide portion 172 is fixed to the upper outer body 128 , and the upper side end of the conversion portion 174 is fixed to the upper inner body 140 .

[0143] A portion of the clean connecting flow path 104 is formed outside the upper inner body 140. The air guide 170 forms a portion of the clean connecting flow path 104. Air passing through the clean connecting flow path 104 flows into the water tank 300 through the upper inlet 121 and the air cleaning inlet 31.

[0144] The upper inner body 140 is formed in a basket shape as a whole. The upper inner body 140 has a circular cross section, and the clean connecting flow path 104 is formed in 360 degrees in all directions.

[0145] The air guide 170 is a structure for guiding filtered air to the clean connection flow path 104 . Depending on the embodiment, the air guide 170 may not be included. The air guide 170 is used to connect the upper inner body 140 or the upper outer body 128 .

[0146] The air guide 170 is formed to cover the upper inner body 140. In particular, the air guide 170 is formed to cover the upper inlet 121 to guide filtered air toward the upper inlet 121. The air guide 170 has a donut shape when viewed from above.

[0147] In this embodiment, the upper end of the air guide 170 is tightly attached to the upper end of the upper inner body 140 .

[0148] When viewed from above, the upper side of the air guide 170 is aligned with the upper side of the upper inner body 140. In this embodiment, an upper inner body ring 126 is formed at the upper end of the upper inner body 140 to be coupled to or in close contact with the air guide 170.

[0149] An inner body extension portion 148 is formed to connect the upper inner body 140 and the upper inner body ring 126. A plurality of inner body extension portions 148 are provided. An upper inlet 121 is formed between the inner body extension portion 148 and the upper inner body ring 126.

[0150] The inner body extension 148 is formed corresponding to the water tank body extension 380. When the water tank 300 is placed, the water tank body extension 380 is located inside the inner body extension 148. The inner body extension 148 and the water tank body extension 380 overlap each other inside and outside.

[0151] The upper end of the air guide 170 is in close contact with or combined with the upper inner body ring 126. The lower end of the air guide 170 is in close contact with or combined with the upper outer body 128.

[0152] Thus, the air flowing through the clean connection flow path 104 between the upper inner body 140 and the upper outer body 128 is guided to the upper inlet 121 .

[0153] The diameter of the upper inner body ring 126 is consistent with or similar to the diameter of the upper end of the air guide 170. The air guide 170 and the upper inner body ring 126 are in close contact with each other to prevent leakage of filtered air. The upper inner body ring 126 is disposed on the inner side of the air guide 170.

[0154] A handle 129 may be formed on the upper outer body 128. The air cleaning module 200 is placed on the upper body 120, and the entire humidification and purification device can be lifted by the handle 129.

[0155] The upper inner body 140 has a water tank insertion space 125 formed therein for inserting the water supply tank 300 .

[0156] The clean connecting flow path 104 is disposed on the outside of the upflow inlet 121, and the water tank insertion space 125 is disposed on the inside. Air flowing along the clean connecting flow path 104 passes through the upflow inlet 121. When the water tank 300 is placed in the water tank insertion space 125, filtered air passing through the upflow inlet 121 flows into the interior of the water tank 300.

[0157] In addition, an outer visible body 214 is coupled to an upper side of the upper body 120 .

[0158] The externally visible body 214 is a structure of the visible body 210, but in this embodiment is fixed to the upper body 120. Unlike this embodiment, the externally visible body 214 can also be fixed to the air cleaning module 200. Unlike this embodiment, the externally visible body 214 is a removable structure.

[0159] The outer visible body 214 is fixed to the upper body 120. In this embodiment, the outer visible body 214 is combined with the upper outer body 128. The outer visible body 214 and the outer side surface of the upper outer body 128 form a continuous surface.

[0160] The outer visible body 214 is formed of a material through which the inner portion can be seen. The outer visible body 214 can be formed of a transparent or translucent material.

[0161] At least one of the air cleaning module 100 or the air washing module 200 may be provided with a display module 160 for displaying the operating status to the user. In this embodiment, the base 110 is provided with a display module 160 for displaying the operating status of the humidification and purification device to the user.

[0162] The display module 160 is disposed inside the outer visible body 214. The display module 160 is disposed in close contact with the inner side of the outer visible body 214. The display module 160 is annular in shape when viewed from above. The water tank 300 is inserted inside the display module 160.

[0163] The display module 160 is supported by the outer visual body 214. The inner edge of the display module 160 is supported by the upper inner body ring 126. The display module 160 is located on the upper side of the air guide 170. The display module 160 can be manufactured in an integral manner with the connector 260.

[0164] The display module 160 is located above the air guide 170. The display module 160 can be disposed between the upper outer body 128 and the upper inner body 140. The display module 160 is configured to cover the space between the upper outer body 128 and the upper inner body 140, thereby preventing a user from viewing the space between the upper outer body 128 and the upper inner body 140. In particular, to prevent water from penetrating between the upper outer body 128 and the upper inner body 140, the inner and outer sides of the display module 160 are preferably sealed.

[0165] The inner side of the display module 160 is supported by the upper inner body 140 , and the outer side is supported by the outer visual body 214 .

[0166] In this embodiment, the display 160 is formed in a ring shape. Different from this embodiment, the display 160 can also be formed in an arc shape. The surface of the display 160 is formed of a material that can reflect light, or is coated with a material that can reflect light.

[0167] Thus, when water accumulates on the visual body 210, the water accumulated on the visual body 210 can be projected or reflected onto the surface of the display 160. When the water accumulated on the visual body 210 falls off, the display 160 will also present the same effect.

[0168] Such an effect provides visual stimulation to the user, allowing the user to intuitively recognize that humidification is in progress. The water drop image projected on the display 160 not only has a sensory effect of providing a refreshing feeling to the user, but also has a functional effect of notifying the user of the humidification status.

[0169] The upper side of the display 160 is formed in an inclined manner. The display 160 is formed in an inclined manner toward the user side. Therefore, the inner side is higher and the outer side is lower.

[0170] Next, each structure of the air cleaning module 200 will be described.

[0171] The air cleaning module 200 humidifies the filtered air. The air cleaning module 200 can create a rain view in the humidification flow path 106. The air cleaning module 200 sprays water from the water tank 300 and circulates the sprayed water. The air cleaning module 200 converts the water into smaller droplets, and the scattered droplets re-clean the filtered air. While the scattered water droplets are washing the filtered air, humidification and filtration are re-performed.

[0172] The air cleaning module 200 includes a humidification connection flow path 105 , a humidification flow path 106 , a discharge flow path 107 , and a water supply flow path 109 .

[0173] The air cleaning module 200 includes a water tank 300 , a watering unit 400 , a humidifying medium 50 , a visible body 210 , a top cover assembly 230 , and a handle 180 .

[0174] The handle 180 is combined with the visual body 210, rotated on the visual body 210, and accommodated in the visual body 210. The handle 180 can be used to easily lift only the air washing module 200 and separate it from the air cleaning module 100.

[0175] The humidification connection flow path 105 may be disposed outside the water tank 300 and guide air into the water tank 300. The humidification connection flow path 105 may be disposed outside the visual body 210 and guide air into the visual body 210.

[0176] The humidification connection flow path 105 may be disposed outside at least one of the water tank 300 and the visible body 210 , and guide air into the inside of the water tank 300 and the visible body 210 .

[0177] The discharge flow path 107 may be disposed between the top cover assembly 230 and the visual body 210. The discharge flow path 107 may be disposed in at least one of the top cover assembly 230 and the visual body 210.

[0178] In this embodiment, a discharge flow path 107 is formed at the outer edge of the top cover assembly 230 , and a water supply flow path 109 is formed at the inner center of the top cover assembly 230 .

[0179] In the humidification and purification device of this embodiment, the air cleaning module 100 is connected to a power source, and the air cleaning module 200 is supplied with power through the air cleaning module 100 .

[0180] Since the air cleaning module 200 is a separable structure relative to the air cleaning module 100 , the air cleaning module 100 and the air cleaning module 200 are provided with a separable power supply structure.

[0181] Since the air cleaning module 100 and the air washing module 200 are detachably assembled through the upper body 120 , a connector 260 for supplying power to the air washing module 200 is provided on the upper body 120 .

[0182] The top cover assembly 230 of the air cleaning module 200 is equipped with an operating unit and a display that require power. The air cleaning module 200 is equipped with a top connector 270 that is detachably connected to the connector 260. The top connector 270 is configured on the top cover assembly 230.

[0183] In this embodiment, since the top cover assembly 230 is detachable, the inner side surface of the visible main body 210 or the inner side surface of the water tank 300 can be easily cleaned.

[0184] The top cover assembly 230 has a water supply passage 109 formed inside and a discharge passage 107 formed between the top cover assembly 230 and the visual body 210. The top cover assembly 230 is detachably mounted relative to the visual body 210. The top cover assembly 230 is provided with a top connector 270 electrically connected to the connector 260.

[0185] When the top cover assembly 230 is placed, the top connector 270 is placed on the upper side of the connector 260. The top cover assembly 230 is supplied with power from the connector 260 through the top connector 270.

[0186] A water level indicator (not shown) is positioned around the water supply path 109 to display the water level in the water tank 300. This allows the user to confirm the water level in the invisible water tank 300 while water is being supplied. Placing the water level indicator along the user's water supply path prevents the user from oversupplying water and prevents the water tank 300 from overflowing.

[0187] The water level display unit is disposed on the top cover assembly 230. The detachable power supply structure of the top connector 270 and the connector 260 can effectively constitute upper water supply.

[0188] The water tank 300 is detachably mounted on the upper body 120. The watering unit 400 is disposed inside the water tank 300 and rotates inside the water tank 300.

[0189] The water tank 300 includes: a water tank body 320 for storing water; an air cleaning inlet 31 formed on the side of the water tank body 320; and a water tank body extension portion 380 extending upward from the water tank body 320 and combined with the visual body 210.

[0190] In this embodiment, the water tank body 320 is formed in a cylindrical shape with an upper side being open. However, unlike this embodiment, the water tank body 320 can be formed in various shapes.

[0191] The water tank body extension 380 is formed to extend upward from the water tank 300. The water tank body extension 380 is used to form the air cleaning inlet 31. The air cleaning inlet 31 is formed between the water tank body extensions 380.

[0192] The air cleaning inlet 31 is formed on a side surface of the water tank body 320. The air cleaning inlet 31 is formed in all directions of 360 degrees relative to the water tank body 320. The air cleaning inlet 31 is connected to the humidification connection flow path 105.

[0193] The water tank body extension portion 380 is used to guide the water flowing down from the inner side of the visual body 210 into the interior of the water tank 300. By guiding the water flowing down from the visual body 210, the falling water noise can be minimized.

[0194] The water tank main body extension portion 380 is combined with the lower end of the visual main body 210 .

[0195] In this embodiment, the air cleaning inlet 31 is formed by the structure of the water tank body 320. Unlike this embodiment, the air cleaning inlet 31 can also be formed by configuring the water tank body extension 380 on the visual body 210. Furthermore, unlike this embodiment, the air cleaning inlet 31 can also be formed by configuring a portion of the multiple water tank body extensions 380 on the water tank 300 and the remaining portions of the multiple water tank body extensions 380 on the visual body 210. Furthermore, unlike this embodiment, the air cleaning inlet 31 can also be formed by a separate structure separate from the visual body 210 and the water tank 300. Furthermore, unlike this embodiment, the air cleaning inlet 31 can also be formed by forming an opening surface on the visual body 210 and also forming an opening surface on the water tank 300.

[0196] That is, the air cleaning inlet 31 may be disposed in at least one of the water tank 300 or the visual main body 210. The air cleaning inlet 31 may be formed by combining the water tank 300 and the visual main body 210. The air cleaning inlet 31 may be disposed in a separate structure separate from the water tank 300 and the visual main body 210, and then disposed between the water tank 300 and the visual main body 210. The air cleaning inlet 31 may be formed by combining the water tank 300 and the visual main body 210.

[0197] The air cleaning inlet 31 is disposed on a side of the air cleaning module 200 and is connected to the humidification flow path 106 . The air cleaning inlet 31 may be communicated with or connected to the humidification connection flow path 105 .

[0198] The watering unit 400 has a function of supplying water to the humidifying medium 50 , a function of visualizing the humidification process, and a function of presenting a rain scene inside the air cleaning module 200 .

[0199] The watering unit 400 rotates a watering housing 800 to draw water from the water tank, pump the water upward, and then spray the pumped water radially outward. The watering unit 400 includes a watering housing 800 that draws water into the water tank, pumps the water upward, and then sprays the water radially outward.

[0200] In this embodiment, the watering housing 800 is rotated to spray water. Unlike this embodiment, a nozzle can be used instead of the watering housing 800 to spray water. Water can be sprayed from the nozzle to supply water to the humidification medium 50, similarly creating a rainy scene. Depending on the embodiment, the nozzle can be rotated to spray water.

[0201] The water sprayed from the watering housing 800 wets the humidifying medium 50. The water sprayed from the watering housing 800 may be sprayed toward at least one of the visual body 210 and the humidifying medium 50.

[0202] The water sprayed toward the visual body 210 can create a rainy scene. The water sprayed toward the humidifying medium 50 is used to humidify the filtered air. This can be achieved by spraying water toward the visual body 210 to create a rainy scene, and then allowing the water flowing from the visual body 210 to wet the humidifying medium 50.

[0203] In this embodiment, a plurality of nozzles at different heights are provided on the watering housing 800. Water ejected from one nozzle forms droplets on the inner surface of the visual body 210 to create a rain scene, while water ejected from another nozzle soaks the humidifying medium 50 for humidification.

[0204] The watering housing 800 sprays water toward the inner side of the visual body 210, and the sprayed water flows downward along the inner side of the visual body 210. Droplets in the form of water droplets are formed on the inner side of the visual body 210, and the user can see the droplets through the visual body 210.

[0205] In particular, the water flowing from the visual body 210 wets the humidifying medium 50 for humidification. The humidifying medium 50 may be wetted by the water sprayed from the watering housing 800 and the water flowing from the visual body.

[0206] The visual body 210 is combined with the water tank 300 and is located on the upper side of the water tank 300. At least a portion of the visual body 210 is formed of a material that allows the interior to be seen through.

[0207] A display module 160 may be disposed outside the visual body 210. The display module 160 may be combined with either the visual body 210 or the upper body 120.

[0208] The display module 160 is disposed on a sight line where the rain scene can be observed. In this embodiment, the display module 160 is disposed on the upper body 120 .

[0209] When the air cleaning module 200 is placed, the outer side of the visual body 210 is in close contact with the display module 160. At least a portion of the surface of the display module 160 may be formed of a light-reflecting material or coated with a light-reflecting material.

[0210] The droplets formed on the visual body 210 are also projected onto the surface of the display module 160 , so that the user can observe the movement of the droplets at both the visual body 210 and the display module 160 .

[0211] The water tank 300 is formed with an air cleaning inlet 31 for air flow. The air cleaning inlet 31 is located between the connecting flow path 103 and the humidifying flow path 106. The air cleaning inlet 31 is the outlet of the connecting flow path 103 and the inlet of the humidifying flow path 106.

[0212] The filtered air supplied from the air cleaning module 100 flows into the air cleaning module 200 through the air cleaning inlet 31 .

[0213] The humidification medium (50) includes a water tank humidification medium (51) disposed at the inlet of the humidification flow path (106) and a discharge humidification medium (55) disposed at the outlet of the humidification flow path (106). The outlet of the humidification flow path (106) and the inlet of the discharge flow path (107) are connected to each other. Therefore, the discharge humidification medium (55) can also be disposed in the discharge flow path (107).

[0214] Since the connecting flow path 103, humidification flow path 106, and discharge flow path 107 are not formed by structures such as ducts, their boundaries are not easily distinguished. However, if the humidification flow path 106 for humidification is defined as the path between the water tank humidification medium 51 and the discharge humidification medium 55, the connecting flow path 103 and discharge flow path 107 can be naturally defined.

[0215] The connecting flow path 103 is defined as a portion between the blower fan housing 150 and the water tank humidifying medium 51. The discharge flow path 107 is defined as a portion after the humidifying medium 55 is discharged.

[0216] In this embodiment, the water tank humidifying medium 51 is disposed at the air cleaning inlet 31 of the water tank 300 .

[0217] The water tank humidification medium 51 may be located at least on the same plane as, outside of, or inside the air cleaning inlet 31. Since the water tank humidification medium 51 is wetted with water for humidification, it is preferably located inside the air cleaning inlet 31.

[0218] The water flowing down after wetting the water tank humidifying medium 51 is preferably stored in the water tank 300. It is preferably configured so that the water flowing down after wetting the water tank humidifying medium 51 does not flow out of the water tank 300.

[0219] Thus, the water tank humidifying medium 51 humidifies the filtered air passing through the air cleaning inlet 31 .

[0220] The filtered air is humidified using water that naturally evaporates from the humidification medium 50. Natural evaporation refers to the evaporation of water without the application of additional heat. Natural evaporation is promoted with increased contact with the air, faster air flow, and lower air pressure. This natural evaporation is also known as natural vaporization.

[0221] The humidifying medium 50 promotes the natural evaporation of water. In this embodiment, the humidifying medium 50 is soaked in water but is not immersed in the water tank 300.

[0222] Because they are separated from the water stored in the water tank 300 and arranged in a phase-separated manner, the water tank humidification medium 51 and the discharge humidification medium 55 are not always wet, even if water is stored in the water tank 300. Specifically, the water tank humidification medium 51 and the discharge humidification medium 55 are wet only when operating in the humidification mode. When operating in the air purification mode, the water tank humidification medium 51 and the discharge humidification medium 55 can remain dry.

[0223] The water tank humidifying medium 51 covers the air cleaning inlet 31 , and air passes through the water tank humidifying medium 51 and flows into the water tank 300 .

[0224] The discharged humidification medium 55 may be disposed at the outlet of the humidification flow path 106 or the inlet of the discharge flow path 107 .

[0225] In this embodiment, the spit humidifying medium 55 is configured to cover the upper portion of the visual body 210. The spit humidifying medium 55 is placed on the visual body 210. Unlike this embodiment, the spit humidifying medium 55 can be combined with the bottom surface of the top cover assembly 230.

[0226] The discharged humidification medium (55) covers the discharge flow path (107), and the humidified air passes through the discharged humidification medium (55) and flows into the discharge flow path (107).

[0227] Figure 6 yes Figure 2 A perspective view of the air cleaning module with the top cover assembly separated is shown. Figure 7 yes Figure 6 The top cover assembly and the humidification medium discharge housing are shown in an isolated perspective view.

[0228] In this embodiment, the top cover assembly 230 is detachably placed on the visual body 210. In addition to providing the discharge flow path 107, the top cover assembly 230 also provides a water supply flow path 109 for water supply.

[0229] In this embodiment, the top cover assembly 230 is located above the discharge humidification medium 55. In this embodiment, a discharge humidification medium housing 1400 having the discharge humidification medium 55 is provided, and the top cover assembly 230 is disposed above the discharge humidification medium housing 1400. The discharge humidification medium housing 1400 is placed above the visible main body 210. The top cover assembly 230 is placed above the discharge humidification medium housing 1400. The top cover assembly 230 can be assembled integrally with the discharge humidification medium housing 1400. In this embodiment, the top cover assembly 230 and the discharge humidification medium housing 1400 are manufactured separately.

[0230] The top cover assembly 230 is placed on the visible body 210 to be supported, and no load is applied to the humidifying medium discharge housing 1400 .

[0231] The discharge humidification medium housing 1400 contains the discharge humidification medium 55 and covers the upper portion of the visible body 210. The water supply path 109 is formed to pass through the discharge humidification medium housing 1400. The discharge path 107 is formed to pass through the discharge humidification medium housing 1400.

[0232] The top cover assembly 230 includes: a top cover grille 232 for forming the discharge flow path 107 and the water supply flow path 109; an operation module 240 disposed on the top cover grille 232; and a top connector 270 for providing power or signals to the operation module 240.

[0233] The top cover grille 232 includes a grille outlet 231, which forms at least a portion of the discharge flow path 107, and a grille water supply port 233, which forms at least a portion of the water supply flow path 109. The grille outlet 231 and the grille water supply port 233 are formed to be open in the vertical direction. The grille water supply port 233 is located at the center of the inner side of the top cover grille 232, while the grille outlet 231 is located outside the grille water supply port 233.

[0234] The top cover grille 232 is detachably placed on the viewing main body 210. The top cover grille 232 is placed on the inner side of the viewing main body 210.

[0235] The operating module 240 is coupled to the top cover grille 232. The operating module 240 receives user input signals and transmits water level information to the user. The operating module 240 is provided with a water supply path 109. The operating module 240 is electrically connected to the top connector 270 and receives power from the top connector 270.

[0236] The operation module 240 includes: an operation shell 250, which is combined with the top cover grille 232 and has at least a portion of the water supply path 109 formed on the inner side; an input part 245, which is arranged on the operation shell 250; a water level display part 247, which is arranged on the operation shell 250; and an operation control part (not shown) which controls the input part 245 and the water level display part 247.

[0237] The operating housing 250 includes an upper operating housing 242 and a lower operating housing 244 .

[0238] The operating module 240 is formed with a water supply path 109. A portion of the water supply path 109 is formed vertically in the center of the operating module 240. The operating module 240 may be provided with an operating water supply port 241 for forming at least a portion of the water supply path 109. The operating water supply port 241 is disposed inside the operating housing and is formed to be open vertically.

[0239] The operation module 240 further includes an upper water supply guide 236. The upper water supply guide 236 guides the water of the upper water supply to the operation water supply port 241. The upper water supply guide 236 is formed by forming a portion of the surface of the operation housing 250 in an inclined manner.

[0240] During the top water supply, the user cannot see the water level inside the water tank 300, but can immediately confirm the rising water level through the water level display unit 247 arranged around the operating water supply port 241. Since the user can confirm the water level through the water level display unit 247 during the top water supply, the user can adjust the top water supply flow rate.

[0241] The water supplied from the upper portion falls toward the humidification flow path 106 through the discharge humidification medium housing 1400. In particular, the water supplied from the upper portion does not fall directly onto the water surface of the water tank 300 but falls toward the upper portion of the watering housing 800.

[0242] When the watering housing 800 is rotating during the upper water supply, the water supplied from the upper part splashes upwards of the watering housing 800, thereby forming an additional rain scene.

[0243] That is, in addition to the water sprayed by the watering unit 400 forming a rain scene, the water supplied from the upper portion can also form a rain scene.

[0244] Figure 8 yes Figure 4 The cross-sectional view of the air cleaning module shown, Figure 9 yes Figure 8 The enlarged view of G is shown. Figure 10 It shows Figure 4The three-dimensional view of the setting state of the watering housing shown, Figure 11 yes Figure 10 The main view, Figure 12 It is along Figure 11 The cross-sectional view taken along the MM line. Figure 13 yes Figure 11 A top view of Figure 14 yes Figure 10 The exploded perspective view of the watering housing shown, Figure 15 It is from Figure 14 A three-dimensional image viewed from the bottom. Figure 16 yes Figure 14 The main view, Figure 17 It is along Figure 16 Cross-sectional view taken along line NN.

[0245] The watering housing 800 is a structure for spraying water stored in the water tank 300. The watering housing 800 is provided with a structure for effectively pumping water stored in the water tank 300.

[0246] The watering housing 800 receives the rotational force of the watering motor 42 and rotates. When rotating, it can suck the water stored in the water tank 300 into the interior and pump it upward. The water pumped into the watering housing 800 is discharged through the injection port 410.

[0247] A water pumping unit is provided in the watering housing 800. The water pumping unit is used to pump water upward from the water tank 300. There are various methods for pumping water from the water tank.

[0248] For example, water may be pumped by the water pump and then sprayed.

[0249] For example, the watering housing is rotated, and during the rotation, water can be pumped up by friction or mutual interference with water.

[0250] Reference Figure 12 and Figure 17 In this embodiment, a structure for pumping water by rotating the watering housing 800 is provided. In this embodiment, the pumping unit is a pumping groove 802 or a pumping rib 810 that pushes water upward through friction or mutual interference with the water.

[0251] A water-lifting rib 810 serving as a water-lifting unit is formed on the inner side surface of the watering shell 800. The water-lifting rib 810 and the water-lifting groove 802 are used to improve the water-lifting efficiency. The water-lifting rib 810 is formed protrudingly on the inner side surface of the watering shell 800. The water-lifting rib 810 is formed to extend long in the up-down direction. The water-lifting rib 810 is arranged radially relative to the watering motor shaft 43 or the transmission shaft 640. A plurality of water-lifting ribs 810 can be arranged on the inner side surface of the watering shell 800. A plurality of water-lifting ribs 810 can be arranged along the peripheral direction (circumferential direction) of the watering shell 800.

[0252] The water-pumping grooves 802 can be disposed between the water-pumping ribs 810. The water-pumping grooves 802 extend vertically. The water-pumping grooves 802 are radially disposed relative to the watering motor 43 or the drive shaft 640. Multiple water-pumping grooves 802 can be disposed on the inner side of the watering housing 800. Multiple water-pumping grooves 802 can be disposed along the periphery (circumferential direction) of the watering housing 800.

[0253] The lower end of the watering housing 800 is separated from the bottom surface of the water tank 300 by a predetermined distance to form a suction gap 801 , H1 . Water from the water tank 300 is sucked into the watering housing 800 through the suction gap 801 .

[0254] The water level H2 of the water tank 300 from which the watering housing 800 can spray water is formed to be higher than the suction space H1 and lower than the spray port 410. The water level H2 includes a full water level.

[0255] When the water level H2 is lower than the suction interval H1, water cannot be pumped because water is not sucked in. When the water level H2 is higher than the injection port 410, water pumped to the injection port 410 cannot be injected.

[0256] The watering housing 800 is formed with its lower side open. The watering housing 800 is in the shape of a cup. The watering housing 800 is in the shape of an inverted cup. A housing space 805 is formed inside the watering housing 800.

[0257] The column 35 of the water tank 300 is located inside the watering housing 800 , and the transmission module 600 is disposed inside the column 35 . The watering housing 800 is disposed in a manner of covering the column 35 .

[0258] The watering housing 800 is formed so that its planar cross-section becomes increasingly larger toward the upper side. The column 35 is formed so that its planar cross-section becomes increasingly smaller toward the upper side. The shapes of the watering housing 800 and column 35 are designed for efficient water pumping. The volume of the housing space 805 increases toward the upper side.

[0259] When the watering housing 800 rotates, the water sucked in will adhere to the inner circumference of the watering housing 800 under the action of centrifugal force. The water pumping grooves 802 or water pumping ribs 810 formed on the inner circumference of the watering housing 800 provide rotational force to the water sucked in.

[0260] The watering housing 800 is provided with a jet port 410 for ejecting the sucked water to the outside. In this embodiment, the jet port 410 is configured to eject water in a horizontal direction. The pumped water is ejected to the outside through the jet port 410.

[0261] In this embodiment, the water ejected from the ejection port 410 may be ejected toward the visual body 210 .

[0262] The number of the spray ports 410 can be adjusted according to design requirements. In this embodiment, multiple spray ports 410 are arranged in a height-differentiated manner on the watering housing 800. The spray port located on the upper side of the watering housing 800 is defined as the second spray port, and the spray port located in the middle of the watering housing is defined as the first spray port.

[0263] The water ejected from the first ejection port is used for humidification. The water ejected from the second ejection port is used for humidification, watering, and rainy scenery.

[0264] The water sprayed from the second spray port can flow down and wet the humidifying medium in the water tank.

[0265] The water ejected from the second ejection port can be scattered to form a rain scene after colliding with the visual subject. The water ejected from the second ejection port can be transformed into tiny droplets after colliding with the visual subject, and these droplets can be used in watering for cleaning and filtering air.

[0266] When the watering housing 800 rotates at a first rotation speed or higher, water may be sprayed from the first spray port. When the watering housing 800 rotates at a second rotation speed or higher, water may be sprayed from the second spray port.

[0267] The second rotation speed is higher than the first rotation speed.

[0268] Water can be ejected from the second ejection port only when the watering housing 800 rotates at high speed. It can be configured so that water cannot be ejected from the second ejection port at the normal rotation speed of the watering housing 800. The first ejection port ejects water during all phases of the watering housing's normal operation.

[0269] The second injection port may be provided in plurality. The first injection port may be provided in plurality.

[0270] When the watering housing 800 rotates at a normal rotation speed, the pumped water rises at least higher than the first jet port. When the watering housing 800 rotates at a high speed, the pumped water rises to a height higher than the second jet port.

[0271] The second spray port may be disposed in plurality along the circumferential direction of the watering housing 800. The first spray port may also be disposed in plurality along the circumferential direction of the watering housing 800.

[0272] When the watering housing 800 is not rotating, water cannot be discharged through the nozzle 410. When the user operates it in only purification mode (a mode in which the air cleaning module is active and the air washing module is inactive), the watering unit 400 does not operate, and only the air supply unit 20 operates. When the user operates it in only humidification mode, the watering housing 800 rotates and discharges water through the nozzle 410. When the user activates both purification and humidification modes, the water discharged from the nozzle 410 can be sprayed toward the inner surface of the visual body 210.

[0273] As the watering housing 800 rotates, the water ejected from the jet port 410 hits the inner side surface of the visual body 210 and moves along the inner side surface of the visual body 210 .

[0274] The user can visually confirm that water is being sprayed through the visual body 210. Such spraying of water indicates that the humidification mode is in operation. The user can intuitively confirm that the humidification mode is in operation through the spraying of water.

[0275] The sprayed water forms droplets on the visual body 210 and flows downward.

[0276] In this embodiment, the watering housing 800 is composed of three parts. Different from this embodiment, the watering housing 800 can be made of one or two parts.

[0277] The lower end of the watering housing 800 is disposed at a predetermined distance from the bottom surface of the water tank 300 .

[0278] The watering housing 800 includes a first watering housing 820 , a second watering housing 840 , a watering housing cover 860 and a watering transmission unit 880 .

[0279] The watering housing 800 is assembled with the transmission shaft 640 and is equipped with a structure for transmitting rotational force from the transmission shaft 640. In this embodiment, in the watering housing 800, the watering transmission unit 880 and the watering housing cover 860 are assembled with the transmission shaft 640. The watering housing 800 is connected to the transmission shaft 640 at two locations, and the rotational force is transmitted from both locations.

[0280] Different from this embodiment, the watering housing 800 may be coupled to the transmission shaft 640 at one location, and the rotational force may be transmitted from the coupled location.

[0281] Furthermore, unlike this embodiment, the watering housing 800 can transmit the rotational force in a manner other than a transmission shaft. For example, the rotational force of the watering motor can be transmitted using a belt and pulley. For example, the rotational force of the watering motor can be transmitted using a gear meshing mechanism. For example, the rotational force of the watering motor can be transmitted using a chain drive mechanism. For example, the rotational force of the watering motor can be transmitted using a clutch mechanism.

[0282] The transmission shaft 640 is formed with threads 643 at the upper and lower ends thereof.

[0283] The upper thread 643 is assembled with the watering housing cover 860. The lower thread is assembled with the second coupler 620. The upper body 120 is provided with a first coupler 610 coupled with the second coupler 620.

[0284] The upper body 120 is provided with a watering motor 42 . The watering motor 42 provides a rotational force to the watering housing 800 .

[0285] The coupler provided in the air cleaning module 100 and coupled to the watering motor 42 is defined as a first coupler 610 . The coupler provided in the air cleaning module 200 and detachably coupled to the first coupler 610 is defined as a second coupler 620 .

[0286] One of the first coupler 610 or the second coupler 620 is male, and the other is female. In this embodiment, the first coupler 610 is male, and the second coupler 620 is female. In this embodiment, the first coupler 610 is inserted into the second coupler 620 to form a detachable connection. Unlike this embodiment, the second coupler 620 can also be inserted into the first coupler 610 to form a connection.

[0287] The watering motor 42 is provided on the upper body 120. The watering motor 42 is located above the air supply motor 22 and is provided separately from the air supply motor 22. The water tank 300 is placed inside the upper body 120. When the water tank 300 is placed on the upper body 120, the first and second couplers 610 and 620 are connected in a transmission manner. The watering motor shaft 43 of the watering motor 42 is arranged to face upward. A first coupler 610 is provided at the upper end of the watering motor shaft 43.

[0288] The various structures of the watering housing 800 will be described.

[0289] The upper and lower sides of the first watering housing 820 are open, and the inner side is formed with a water-lifting groove 802 and / or a water-lifting rib 810. The lower end of the first watering housing 820 is separated from the bottom surface of the water tank 300 by a predetermined distance, thereby forming a suction gap 801.

[0290] The upper side and the lower side of the second watering shell 840 are respectively formed in an open state and assembled on the upper end of the first watering shell 820. Figure 12 As shown, the upper end of the first watering housing 820 can be inserted into the lower end of the second watering housing 840.

[0291] The watering housing cover 860 is combined with the upper end of the second watering housing 840 and covers the upper surface of the second watering housing 840 .

[0292] The watering transmission part 880 is connected to at least one of the first watering housing 820 or the second watering housing 840 to transmit the rotational force to the transmission module 600. In this embodiment, the watering transmission part 880 is connected to the first watering housing 820.

[0293] Different from the present embodiment, the first watering housing 820 and the second watering housing 840 can be manufactured in an integral manner. Also, different from the present embodiment, the first watering housing 820 and the watering housing cover 860 can be manufactured in an integral manner.

[0294] The upper cross-section of the first watering housing 820 is wider than the lower cross-section. The first watering housing 820 is inclined in the vertical direction. The first watering housing 820 may be in the form of a cone with a narrow lower cross-section.

[0295] A water rib 810 is formed inside the first watering housing 820. The water rib 810 is formed in the vertical direction. The water rib 810 is arranged radially around the watering motor shaft 43. There can be multiple water ribs 810, which protrude toward the center of the watering housing 800.

[0296] The lower end of the first watering shell 820 is separated from the inner bottom surface of the water tank 300 to form a suction gap 801. The upper end of the first watering shell 820 is combined with the lower end of the second watering shell 840. Figure 12As shown, the upper end of the first watering housing 820 and the lower end of the second watering housing 840 may overlap radially. The lower end of the second watering housing 840 may be located further outboard of the upper end of the first watering housing 820. The overlapping portion of the first and second watering housings 820 and 840 may be referred to as the boundary between the first and second watering housings 820 and 840. The boundary may include the first baffle 823, described later. Specifically, the boundary may include the overlapping portion of the first and second watering housings 820 and 840 and the first baffle 823. The boundary may form a step between the first watering housing 820 and the second watering housing 840. The boundary may form a step on the inner side of the watering housing 800. Alternatively, the boundary may form a step on the outer side of the watering housing 800. The width of the portion of the watering housing 800 located above the step may be greater than the width of the portion located below the step. The width of the second watering housing 840 may be greater than the width of the first watering housing 820.

[0297] And, as Figure 12 As shown, the step can be arranged at a position higher than the water-lifting rib (810, lower rib). The step can be located at a position higher than the upper end of the water-lifting rib 810.

[0298] And, as Figure 12 As shown, the water film suppression ribs (870, the rib portion of the upper rib) can be located above the step, and the watering connection portion (884, the connection portion) can extend from a position above the step to a position below the step. The step can be located at a height between the upper and lower ends of the upper ribs 870 and 884, including the water film suppression ribs 870 and the watering connection portion 884.

[0299] The first watering housing 820 and the second watering housing 840 can be assembled or disassembled. In this embodiment, the first watering housing 820 and the second watering housing 840 are assembled by screws. Threads 822 are formed on the upper outer surface of the first watering housing 820, and threads 842 are formed on the lower inner surface of the second watering housing 840.

[0300] The thread 822 formed on the first watering housing 820 is defined as a first thread 822 , and the thread 842 formed on the second watering housing 840 is defined as a second thread 842 .

[0301] A first barrier 823 is formed below the first thread 822 to restrict movement of the second watering housing 840. The first barrier 823 is formed along the circumference of the first watering housing 820. The first barrier 823 is formed in a belt shape and protrudes outward from the first watering housing 820.

[0302] When the first watering housing 820 and the second watering housing 840 are assembled, the first baffle 823 is closely attached to the lower end of the second watering housing 840. The first baffle 823 is formed to be more protruding outward than the first thread 822.

[0303] A first gasket 825 is disposed between the first thread 822 and the first baffle 823. The first gasket 825 is used to prevent water from leaking between the first watering housing 820 and the second watering housing 840. The first gasket 825 is formed of an elastic material and is in the shape of a ring.

[0304] In order to fix the position of the first gasket 825, a gasket setting rib 824 is configured. The gasket setting rib 824 can be configured on the extension line of the first thread 822. The gasket setting rib 824 can be a part of the first thread 822.

[0305] Thus, the first thread 822 may be formed in plurality and dispersedly arranged in a discontinuous manner, one of which may be used to provide the rib 824 for the gasket.

[0306] The first watering housing 820 is provided with a first spray port 411. In this embodiment, two first spray ports 411 are provided. The two first spray ports 411 are formed in opposite directions.

[0307] The first spray port 411 connects the inside and outside of the first watering housing 820. In this embodiment, the inside opening area of ​​the first spray port 411 is wider than the outside opening area. The first spray port 411 supplies water to the water tank humidifying medium 51, soaking the water tank humidifying medium 51. The first spray port 411 can spray toward the water tank humidifying medium 51.

[0308] Watering wings 850 are formed on the outer circumference of the second watering housing 840. These wings 850 circulate humidified air. When the watering housing 800 rotates, the wings 850 draw in surrounding air. In addition to circulating air, these wings also function as rain effect devices that refine droplets.

[0309] The air in the humidification flow path 106, where the watering housing 800 is located, mostly flows toward the discharge flow path 107 due to the rotation of the blower fan 24, while the air around the watering wings 850 can flow in the opposite direction. The watering wings 850 can locally create an air flow opposite to the air flow from the blower fan 24. Depending on the shape of the watering wings 850, it is also possible to direct the air flow in the same direction as the air flow from the blower fan 24. In this case, the rotation of the watering wings 850 can also cause the air around the watering housing 800 to converge onto the surface of the watering housing 800.

[0310] The air flow by the watering wings 850 has the effect of causing the water particles around the watering housing 800 to flow toward the water tank 300. The rotation of the watering wings 850 has the effect of generating air volume and drawing in the water particles around the watering housing 800.

[0311] Thus, when water falls from the water supply channel 109 to the upper portion of the watering housing 800 , the air flow caused by the watering wings 850 can collect the falling water toward the watering housing 800 .

[0312] When the watering housing 800 rotates and water is supplied through the water supply passage 109, water may collide with the surface of the watering housing 800 and be scattered irregularly. The air flow caused by the watering wings 850 can collect the scattered water particles toward the surface of the watering housing 800.

[0313] The second watering housing 840 is formed with second spray ports 412 and 413. The second spray ports 412 and 413 spray water toward the visible body 210. In this embodiment, two second spray ports 412 and 413 are provided. One of the second spray ports is defined as the 2-1 spray port 412, and the other is defined as the 2-2 spray port 413.

[0314] The 2-1st injection port 412 and the 2-2nd injection port 413 are arranged in different directions. In this embodiment, the 2-1st injection port 412 and the 2-2nd injection port 413 are arranged in opposite directions. The 2-1st injection port 412 and the 2-2nd injection port 413 can be arranged symmetrically with respect to the transmission shaft 640.

[0315] When viewed from above, the 2-1st injection port 412 and the 2-2nd injection port 413 form an angle of 180 degrees. When viewed from above, the 2-1st injection port 412 is disposed between the watering wings 850. The 2-2nd injection port 413 is also disposed between the watering wings 850.

[0316] When viewed from the front, the 2-1st and 2-2nd jet ports 412, 413 are provided at the same height as or higher than the watering wing 850. Parts of the trajectories S3 and S4 of the water sprayed from the 2-1st and 2-2nd jet ports 412, 413 are located within the rotation radius of the watering wing 850.

[0317] Therefore, when the watering housing 800 rotates, a portion of the water sprayed from the 2-1 spray port 412 and the 2-2 spray port 413 collides with the watering wings 850 and is scattered.

[0318] In this embodiment, a predetermined height difference is formed between the 2-1st injection port 412 and the 2-2nd injection port 413. The 2-1st injection port 412 and the 2-2nd injection port 413 are not arranged at the same height.

[0319] By forming a height difference between the 2-1st and 2-2nd jet ports 412 and 413, the position of the water colliding with the visual body 210 can be set differently. As a result, when the watering housing 800 rotates, the water ejected from the 2-1st and 2-2nd jet ports 413 will take different paths.

[0320] A trajectory S3 of water ejected from the second ejection ports 412 and 413 and colliding with the inner side surface of the visible body 210 is defined as an ejection line.

[0321] The injection line formed by the 2-1 injection port 412 is defined as a first injection line L1, and the injection line formed by the 2-2 injection port 413 is defined as a second injection line L2.

[0322] The jet line formed on the visible body 210 does not necessarily mean a straight line, but may be curved depending on the angle at which the jet is ejected from the jet port.

[0323] Furthermore, the thickness of the jet line can be formed differently according to the diameter of the jet port. That is, when the diameter of the jet port is large, the jet line is formed thicker, and when the diameter is small, the jet line is formed thinner.

[0324] In this embodiment, water ejected from the 2-1st ejection port 412 passes through a certain point on the visual body 210, and then, after a predetermined time, passes through water ejected from the 2-2nd ejection port 413 at a different height. In other words, two ejection lines L1 and L2 are formed on the inner side surface of the visual body 210. This visual effect allows the user to more effectively recognize that water is being ejected.

[0325] When water is ejected from two second jet ports arranged at a constant height, only one jet line is formed. When the watering housing 800 rotates at high speed, even if the two second jet ports 412 and 413 are located in opposite directions, the phase difference between them is extremely short. In this case, a visual illusion occurs, causing the water to appear to flow from a single jet line.

[0326] Furthermore, when two jet lines are formed, the sound produced by the collision will also be different due to the different locations where the water impacts. That is, the sound produced by the first jet line and the sound produced by the second jet line will be different. This acoustic difference allows the user to auditorily confirm that the watering housing 800 is rotating.

[0327] When only one jet line is formed, the same sound is continuously generated, and the user may not be able to recognize it or may mistake it for simple noise.

[0328] The acoustic differences of the plurality of jet lines effectively convey the operating status to the visually impaired or hearing impaired. Furthermore, even in the absence of light, it is easy to confirm that the humidification and purification device is in operation.

[0329] A portion of at least one of the second injection ports 412 and 413 may be covered by the watering housing cover 860. In this embodiment, the 2-1 injection port 412 is configured in a fully open state, and a portion of the 2-2 injection port 413 is overlapped and covered by the watering housing cover 860.

[0330] The watering housing cover 860 is located in front of the 2-2 injection port 413. The watering housing cover 860 covers a portion of the upper side of the 2-2 injection port 413.

[0331] In this embodiment, when the watering housing cover 860 is coupled to the second watering housing 840, it overlaps a portion of the 2-2nd spray port 413. In this embodiment, the watering housing cover 860 functions as a diffusion member. Unlike this embodiment, an additional diffusion member may be provided to diffuse the water sprayed from the spray port more widely.

[0332] For example, when the watering housing is injection-molded, burrs may be intentionally formed so that the sprayed water is diffused through the burrs.

[0333] The water injected from the 2-2 injection port 413 interferes with the diffusion member, causing the injection angle and width to change. The water that interferes with the diffusion member is pulled toward the diffusion member due to surface tension.

[0334] The 2-1st jet port 412, which does not overlap with the diffuser, has a diameter similar to the diameter of the discharged water. The 2-2nd jet port 413, which overlaps with the watering housing cover 860, sprays water over a wider range than the jet port diameter.

[0335] The trajectory of the water ejected from the 2-1 ejection port 412 is defined as S3, and the trajectory of the water ejected from the 2-2 ejection port 413 is defined as S4.

[0336] The 2-2nd injection port 413 is located slightly higher than the 2-1st injection port 412. A portion of the 2-2nd injection port 413 overlaps with a cover body boarder 863 of a watering housing cover 860 serving as a diffusion member.

[0337] Since the water injected through the 2-2 injection port 413 interferes with the cover body plate 863 and is injected, the injected water is further atomized and injected.

[0338] The droplets ejected from the 2-2 ejection port 413 are smaller than the droplets ejected from the 2-1 ejection port 412. The trajectory S4 of the droplets ejected from the 2-2 ejection port 413 is formed at a higher position than the trajectory S3 of the droplets ejected from the 2-1 ejection port 412. The droplets ejected from the 2-2 ejection port 413 are ejected more widely than the droplets ejected from the 2-1 ejection port 412. As a result, the width of the jet line L2 formed by the superimposed 2-2 ejection port 413 is wider than the jet line L1 formed by the 2-1 ejection port 412.

[0339] Furthermore, the watering wings 850 can not only circulate the air around the watering housing 800 but also atomize the water sprayed from the spraying port 410 .

[0340] In this embodiment, the water injected from the second injection ports 412 and 413 collides with the watering wings 850 and is atomized. The watering wings 850 can atomize the water into a mist form.

[0341] The watering wings 850 do not atomize all of the water sprayed from the second spray ports 412 and 413. Some of the water sprayed from the second spray ports 412 and 413 collides with the watering wings 850.

[0342] The water ejected from the two ejection ports 412 and 413 forms a predetermined trajectory S3, and the rotating watering wings 850 collide with the water on the trajectory S3. Specifically, a portion of the water ejected from the second ejection ports 412 and 413 collides with the watering wings 850 and is dispersed, while the remaining water does not collide with the watering wings 850 but instead collides with the inner surface of the visual body 210.

[0343] Water that collides with the watering wings 850 is dispersed widely in the humidification flow path 106, rather than being dispersed in a specific direction. For example, the water dispersed from the watering wings 850 can soak the discharged humidification medium 55. The water dispersed from the watering wings 850 can condense on the visual body 210. The water dispersed from the watering wings 850 can float on the humidification flow path 106.

[0344] The water atomized by the watering wings 850 can effectively create a rain scene. The atomized droplets form smaller droplets on the inner surface of the visual body 210.

[0345] Instead of the watering wings 850, a rain scene effect unit can be disposed between the watering housing 800 and the visual main body 210. Water ejected from the ejection port 410 can collide with the rain scene effect unit and be dispersed. For example, a mesh can be disposed between the visual main body 210 and the watering housing 800 as the rain scene effect unit. Water ejected from the watering housing 800 can be broken into smaller droplets as it passes through the mesh before being dispersed.

[0346] In addition, the rain scene generated in the humidification flow path 106 can generate anions due to the Lenard effect.

[0347] The Renard effect is a phenomenon in which a large amount of anions are generated when water is crushed by a large external force.

[0348] During the rain scene, the droplets fly and collide with each other, generating a large number of anions in the process.

[0349] When the water injected from the first injection port 411 collides with the structure, anions are generated due to the Renard effect.

[0350] Furthermore, when the water ejected from the second ejection ports 412 and 413 collides with the visible body 210 , negative ions are generated due to the Renard effect.

[0351] Furthermore, when the water injected from the second injection ports 412 and 413 collides with the watering blades 850 , anions are generated due to the Renard effect.

[0352] Furthermore, when water is supplied from the upper portion, when droplets flying from the watering housing cover 860 collide with various structures, negative ions may be generated due to the Lenard effect.

[0353] As described above, in this embodiment, the droplets of various sizes used to create a rain scene have the effect of generating anions during the generation process. The generated anions are discharged into the room through the discharge flow path 107 .

[0354] In addition, refer to Figure 12 and Figure 14 Inside the second watering housing 840, water film suppression ribs 870 are formed to suppress the rotational flow of the water film. The rotational flow of the water film refers to the flow that rotates along the inner surface of the watering housing 800. The water film suppression ribs 870 can be positioned above the water lifting ribs 810. Hereinafter, the water film suppression ribs 870 and the watering connection portion 884 are referred to as upper ribs 870 and 884. Furthermore, the water lifting rib 810 is referred to as lower rib 810. Furthermore, the water film suppression ribs 870, 884, and the water lifting rib 810 can also be distinguished as first and second ribs. The watering connection portion 884 can extend from the water film suppression rib 870 toward the rotation center of the watering housing 800. The watering connection portion 884 can extend to a position below the upper end of the water lifting rib 810.

[0355] And, as Figure 12 As shown, the upper ribs 870 and 884 and the lower rib 810 may be arranged at different positions in the circumferential direction of the watering housing 800 .

[0356] The water-lifting ribs 810 of the first watering shell 820 are used to form the rotating flow of the water film, and the water-film suppressing ribs 870 are used to suppress the rotating flow of the water film.

[0357] In the first watering shell 820, since water needs to be pumped up to the second watering shell 840, a water film rotation flow will be actively generated. The less the water rising to the second watering shell 840 forms a water film rotation flow, the easier it is to be ejected through the second injection ports 412 and 413.

[0358] When a high-speed water film rotation flow is formed inside the second watering housing 840, the water will flow along the inside instead of being ejected through the second injection port.

[0359] Furthermore, the more water is retained in the second watering housing 840, the greater the vibration generated in the watering housing 800. The water pumped into the second watering housing 840 needs to be quickly ejected through the second ejection ports 412 and 413 to minimize the eccentricity of the watering housing 800 and the corresponding vibration.

[0360] The water film suppression ribs 870 are used to minimize the rotational flow of the water film, thereby minimizing the eccentricity and vibration of the watering housing 800.

[0361] The water film suppression ribs 870 are formed protrudingly on the inner side of the second watering housing 840. In this embodiment, the water film suppression ribs 870 are formed protrudingly toward the transmission shaft 640. The water film suppression ribs 870 are formed in a direction intersecting the rotating flow of the water film.

[0362] The water film rotates and flows in a spiral or circular shape along the inner side surface of the second watering shell 840, and the water film suppression ribs 870 are preferably formed along the up and down directions.

[0363] In this embodiment, the water film suppression ribs 870 are formed along the vertical direction. The water film suppression ribs 870 can be formed in multiples. In this embodiment, the water film suppression ribs 870 are configured in threes. The multiple water film suppression ribs 870 are configured at equal intervals relative to the inner circumference of the watering shell. Figure 12 、 Figure 14 as well as Figure 15 As shown, the intervals between the plurality of water film suppression ribs 870 may be greater than the intervals between the plurality of water lifting ribs 810. The number of the plurality of water film suppression ribs 870 may be less than the number of the plurality of water lifting ribs 810.

[0364] In this embodiment, the protruding length of the water film suppression rib 870 is 5 mm. The protruding length of the water film suppression rib 870 is related to the thickness of the rotating water film flow and can be varied according to the embodiment.

[0365] In this embodiment, the water film suppression ribs 870 are formed in a manner connected to the watering transmission part 880. Different from this embodiment, the water film suppression ribs 870 and the watering transmission part 880 can be configured in a manner of being separated.

[0366] In this embodiment, the mold can be simplified by manufacturing the water film suppression rib 870 and the watering transmission part 880 in a manner of connecting them.

[0367] The watering transmission part 880 is a structure for transmitting the rotational force of the transmission shaft 640 to the watering housing 800 .

[0368] In this embodiment, the watering transmission part 880 is connected to the second watering housing 840. Different from this embodiment, the watering transmission part 880 can be connected to the first watering housing 820.

[0369] In this embodiment, the watering transmission part 880 is manufactured in an integral manner with the second watering housing 840. Unlike this embodiment, the watering transmission part 880 can be manufactured separately and then assembled with the second watering housing 840.

[0370] The watering transmission unit 880 includes a bushing installation portion 882 located at the axis center of the watering housing 800 and a watering connection portion 884 connecting the bushing installation portion 882 and the watering housing 800. In this embodiment, the bushing installation portion 882, the watering connection portion 884, and the second watering housing 840 are integrally manufactured by injection molding.

[0371] The watering connection part 884 is made into a rib shape. The watering connection part 884 is arranged radially with the axis center as the reference, and is formed in plurality. Figure 12 As shown, the watering connection portion 884 may be inclined downward along the radial inner side of the watering housing 800. The upper side frame (or upper side edge) of the watering connection portion 884 may be inclined upward along the radial outer side of the watering housing 800. The lower side frame (or lower side edge) of the watering connection portion 884 may be inclined upward along the radial outer side of the watering housing 800.

[0372] In this embodiment, the watering connection portion 884 and the water film suppression ribs 870 are integrally formed. The watering connection portion 884 and the water film suppression ribs 870 are connected to each other. The watering connection portion 884 and the water film suppression ribs 870 can also be referred to as upper ribs 870, 884. The watering connection portion 884 can also be referred to as the connection portion 884, and the water film suppression ribs 870 can also be referred to as the rib portion 870.

[0373] The transmission shaft 640 is installed through the bushing installation portion 882 .

[0374] The lower side of the bushing installation portion 882 is formed in an open state. A bushing 90 is inserted through the lower side of the bushing installation portion 882 in the open state.

[0375] The bushing setting portion 882 and the bushing 90 can be separated in the up-down direction. The bushing setting portion 882 and the bushing 90 are locked with each other in the rotation direction.

[0376] To this end, a bushing locking portion 93 is formed on one of the bushing setting portion 882 or the bushing 90, and a bushing locking groove 883 is formed on the other. In this embodiment, the bushing locking portion 93 is formed on the bushing 90, and the bushing locking groove 883 is formed on the bushing setting portion 882.

[0377] The bushing retaining groove 883 is formed on the inner side of the bushing setting portion 882 and has a concave shape. The bushing retaining portion 93 is formed on the outer side of the bushing 90 and has a convex shape.

[0378] The bushing locking portion 93 is inserted into the bushing locking groove 883 and clamped.

[0379] Unlike this embodiment, the bushing installation portion 882 and the bushing 90 can be manufactured in an integral manner. Since the bushing 90 is formed of a metal material, when manufacturing the second watering housing 840, the bushing 90 can be placed in a mold and then the second watering housing material can be injection molded to form the second watering housing in an integral manner.

[0380] The bushing 90 is combined with the transmission shaft 640 of the transmission module 600 .

[0381] The bushing 90 is coupled to the transmission shaft 640 to transmit the rotational force. The bushing 90 is preferably formed of a metal material. If the bushing 90 is not made of a hard metal material, it may wear out, which may cause vibration.

[0382] The bushing 90 is formed with a bushing shaft hole extending vertically therethrough, and the transmission shaft 640 is inserted into the bushing shaft hole.

[0383] The bushing 90 is used to reduce vibration when the watering housing 800 rotates. The bushing 90 is located on the transmission shaft 640. In this embodiment, the bushing 90 is located at the center of gravity of the watering housing 800. Because the bushing 90 is located at the center of gravity of the watering housing 800, vibration of the watering housing 800 can be significantly reduced during rotation.

[0384] The bushing 90 and the transmission shaft 640 are assembled in a clamping manner. The bushing 90 is supported by the transmission shaft 640 .

[0385] In order to support the bushing 90, the transmission shaft 640 is formed with a shaft support end 642. With the shaft support end 642 as a reference, the diameter of the upper side is small, and the diameter of the lower side is large.

[0386] The bushing 90 is inserted through the upper end of the transmission shaft 640 .

[0387] In order to minimize the wear and tear generated, the shaft support end 642 can be formed into a cone, a cavity or a shape with an arc. When the shaft support end 642 is formed into a right angle, wear and tear may occur during the assembly process or the operation process.

[0388] If the shaft support end 642 is worn, it may cause the bushing 90 to move and cause vibration. Furthermore, if the shaft support end 642 is worn, the bushing 90 may tilt or move, causing misalignment with the transmission shaft 640. Furthermore, if the bushing 90 and transmission shaft 640 are misaligned, eccentricity may occur during rotation, causing vibration.

[0389] The watering housing cover 860 is combined with the upper side of the second watering housing 840 to close the upper side of the second watering housing 840. The watering housing cover 860 is combined with the second watering housing 840 in a screw manner.

[0390] In this embodiment, the watering housing cover 860 is assembled with the transmission module 600. Different from this embodiment, the watering housing cover 860 can also be separated from the transmission module 600.

[0391] When the watering housing cover 860 is combined with the transmission shaft 640 , the eccentricity and vibration of the watering housing 800 can be more effectively reduced.

[0392] The watering shell cover 860 includes: a cover body 862, covering the upper opening of the second watering shell 840; a cover body plate 863, extending downward from the cover body 862, covering the upper end of the second watering shell 840; a gasket setting rib 864, formed on the lower side of the cover body 862, separated from the cover body plate 863 by a specified interval; an axis fixing portion 866, fixed to the transmission shaft 640; and a reinforcing rib 868, connecting the axis fixing portion 866 and the gasket setting rib 864.

[0393] The cover body 862 is formed in a circular shape when viewed from above. The diameter of the cover body 862 is formed to be larger than the diameter of the second watering housing 840.

[0394] Unlike this embodiment, the planar shape of the cover body 862 may not be circular. Furthermore, the planar shape of the watering housing 800 is not limited to a specific shape.

[0395] The cover body plate 863 forms the periphery of the cover body 862. The cover body plate 863 is formed in a ring shape and is manufactured integrally with the cover body 862. The cover body plate 863 has a plurality of protrusions 861 formed on its outer surface, extending 360 degrees along the circumference. These protrusions 861 provide a user with a grip when detaching the watering housing cover 860.

[0396] Furthermore, the protrusions 861 effectively disperse water that falls during the top water supply. Water falling from the top water supply falls onto the watering housing cover 860 and, due to the rotation of the watering housing 800, flows toward the cover body plate 863. Subsequently, after separating from the protrusions 861 in the form of water droplets, it is thrown toward the inner surface of the visual body 210. The protrusions 861 effectively disperse the water from the top water supply.

[0397] The gasket rib 864 is located inside the cover body plate 863 and is separated from the cover body plate 863 by a predetermined distance. A second gasket 865 is provided between the cover body plate 863 and the gasket rib 864.

[0398] The second gasket 865 can seal the watering housing cover 860 and the second watering housing 840. Since the first gasket 825 and the second gasket 865 prevent water leakage from the housing space 805, the pressure of water ejected from the ejection port 410 can be kept constant.

[0399] If water leakage occurs between the first watering housing 820 and the second watering housing 840 or between the second watering housing 840 and the watering housing cover 860 , it will be difficult to maintain a constant pressure of water ejected from the ejection port 410 .

[0400] That is, if water leakage occurs in the watering housing 800 , water may not be sprayed from the spray port 410 even if the watering housing 800 rotates.

[0401] The cover body plate 863 and the second watering shell 840 can be combined by screws. In this embodiment, the watering shell cover 860 and the second watering shell 840 are assembled in an interference fit manner.

[0402] The shaft fixing portion 866 is assembled with the transmission shaft 640 to transmit the rotational force from the transmission shaft 640 .

[0403] The shaft fixing portion 866 and the transmission shaft 640 can be screwed together. To this end, a thread 643 for screwing with the watering housing cover 860 is formed on the outer peripheral surface of the upper end of the transmission shaft 640.

[0404] The shaft fixing portion 866 may be formed with threads for assembly with the transmission shaft 640. In this embodiment, the shaft fixing portion 866 is provided with a shaft fixing member 867, which is integrated with the shaft fixing portion 866 through dual injection molding. In this embodiment, a nut is used as the shaft fixing member 867.

[0405] Unlike the watering housing cover 860, the shaft securing member 867 is made of metal. Since the transmission shaft 640 is made of metal, the portion screwed to the transmission shaft 640 must also be made of metal to prevent wear and damage during the connection. If the watering housing cover 860 is entirely made of metal, or if the shaft securing portion 866 is made of metal, threads are preferably formed on the shaft securing portion 866 itself.

[0406] The watering housing cover 860 is formed to have a larger diameter than the second watering housing 840. When viewed from the top, only the watering housing cover 860 is exposed, while the second watering housing 840 and the first watering housing 820 are not exposed.

[0407] Thus, at least a portion of the water supplied to the water supply passage 109 can fall toward the watering housing cover 860. When the watering housing 800 rotates, the water falling toward the watering housing cover 860 is sprayed radially outward on the surface of the watering housing cover 860.

[0408] The rotating watering housing cover 860 sprays the supplied water along the rotation direction, which can produce an effect similar to water falling from an umbrella. In particular, the water droplets can be peeled off by the plurality of protrusions 861 arranged along the circumference of the watering housing cover 860.

[0409] The water ejected from the watering housing cover 860 in the rotation direction collides with the inner side surface of the visual body 210, thereby creating a rain scene.

[0410] The rain scene refers to the situation where the liquid droplets formed on the inner surface of the visual body 210 appear to be falling like raindrops.

[0411] Reference Figure 12 In this embodiment, the water-lifting ribs 810 are designed to effectively lift water from the water tank 300. In this embodiment, the water-lifting ribs 810 are located lower than the jet outlet 410. In particular, the water-lifting ribs 810 are formed lower than the first jet outlet 411.

[0412] The water-lifting ribs 810 convert the horizontal rotational force of the water into a vertical force. When the water-lifting ribs 810 are formed, water can be lifted more effectively in the vertical direction.

[0413] In this embodiment, the water-lifting ribs 810 are formed on the inner side of the watering housing 800 and protrude inward. These ribs 810 extend vertically. Unlike this embodiment, the ribs 810 can be formed in a zigzag pattern. In this embodiment, since the first watering housing 820 is injection molded, the vertical arrangement of the ribs 810 facilitates removal from the mold.

[0415] The humidification medium discharge housing will be described in more detail with reference to the accompanying drawings.

[0416] In this embodiment, a housing in which the discharge humidification medium 55 is provided in the humidification medium 50 is defined as a discharge humidification medium housing 1400 .

[0417] In this embodiment, the discharge humidification medium housing 1400 is disposed on the discharge flow path 107. The discharge humidification medium housing 1400 may be provided on the top cover assembly 230. The discharge humidification medium housing 1400 may be manufactured integrally with the top cover assembly 230.

[0418] In this embodiment, the humidifying medium housing 1400 is manufactured as a separate structure from the top cover assembly 230. The humidifying medium housing 1400 is disposed below the top cover assembly 230. The humidifying medium housing 1400 can be detachably assembled to the top cover assembly 230. In this embodiment, the humidifying medium housing 1400 is placed on the visible body 210.

[0419] The top cover assembly 230 forms a portion of the water supply flow path 109 and exposes a water supply cap 1430 to be described later to a user.

[0420] The humidification medium housing 1400 allows air to pass outward and water to pass inward, with air passing from the bottom to the top and water passing from the top to the bottom.

[0421] The discharge humidification medium housing 1400 has a discharge flow path 107 for allowing air to pass through on the outside and a water supply flow path 109 for allowing water to pass through on the inside.

[0422] The discharge humidification medium housing 1400 includes an upper housing 1410 , a lower housing 1420 , and a water supply cap 1430 . The discharge humidification medium 55 is disposed between the upper housing 1410 and the lower housing 1420 .

[0423] The upper housing 1410 and the lower housing 1420 are formed with a plurality of gaps.

[0424] The upper housing 1410 is formed in a circular ring shape as a whole.

[0425] The upper shell 1410 includes: an upper inner frame 1412 (upper inner frame), which is arranged in the center; an upper shell opening 1415, which is formed in the center of the upper inner frame 1412 and provides a water supply path 109; an upper outer frame 1414, which is separated from the upper inner frame 1412 and arranged on the outer contour; and an upper screen frame 1416, which connects the upper inner frame 1412 and the upper outer frame 1414.

[0426] The lower housing 1420 is formed in a circular ring shape as a whole.

[0427] The lower shell 1420 includes: a lower inner frame 1422, which is arranged in the center; a lower shell opening 1425, which is formed in the center of the lower inner frame 1422 and provides a water supply path 109; a lower outer frame 1424, which is separated from the lower inner frame 1422 and arranged on the outer contour; and a lower screen frame 1426, which connects the lower inner frame 1422 and the lower outer frame 1424.

[0428] The shapes of the upper shell 1410 and the lower shell 1420 correspond to each other.

[0429] The upper shell opening 1415 and the lower shell opening 1425 are connected to each other.

[0430] The upper shell 1410 and the lower shell 1420 are assembled with each other. In this embodiment, the upper shell 1410 and the lower shell 1420 are clamped together. To this end, one of the upper shell 1410 or the lower shell 1420 is formed with a clamping protrusion 1411, 1413, and the other is formed with a clamping groove 1421, 1423.

[0431] In this embodiment, the clamping protrusions 1411 and 1413 are formed on the upper housing 1410, and the clamping grooves 1421 and 1423 are formed on the lower housing 1420. The clamping protrusions are respectively formed on the upper inner frame 1412 and the upper outer frame 1414. The clamping grooves are respectively formed on the lower inner frame 1422 and the lower outer frame 1424.

[0432] The water supply cap 1430 may be coupled to at least one of the upper housing 1410 or the lower housing 1420. In this embodiment, the water supply cap 1430 is detachably clamped to the lower housing 1420. Unlike this embodiment, the water supply cap 1430 may be detachably mounted on the upper housing 1410.

[0433] In order to detachably combine the water supply cap 1430 and the lower housing 1420 , a combining protrusion 1437 and a combining groove 1427 are formed.

[0434] A coupling protrusion 1437 is formed on one of the water supply cap 1430 and the lower shell 1420 , and a coupling groove 1427 is formed on the other. In this embodiment, the coupling protrusion 1437 is formed on the water supply cap 1430 and the coupling groove 1427 is formed on the lower shell 1420 .

[0435] The coupling protrusion 1437 and the coupling groove 1427 form a clamping connection in the horizontal direction.

[0436] The coupling protrusion 1437 is formed to protrude radially outward from the water supply cap 1430 . The coupling groove 1427 is formed to be open toward the center of the lower case 1420 .

[0437] The three engaging protrusions 1437 are arranged at equal intervals, and the engaging grooves 1427 are formed corresponding thereto. Furthermore, the engaging grooves 1427 are formed with engaging protrusion locking portions 1428 that engage with the engaging protrusions 1437. The engaging protrusion locking portions 1428 provide mutual engagement with the lower housing 1420 in the radial direction.

[0438] The engaging protrusion locking portion 1428 may be formed to protrude toward the radial inner side of the lower shell 1420 .

[0439] After inserting the water supply cap 1430 into the lower housing opening 1425, the user can rotate it clockwise to engage the engagement protrusion 1437 with the engagement groove 1427. During the engagement between the engagement protrusion 1437 and the engagement groove 1427, the engagement protrusion 1437 passes over the engagement protrusion locking portion 1428, producing a "click" operation sound and operation feel.

[0440] Furthermore, the discharge humidification medium housing 1400 is provided with a water supply structure 1440 that temporarily stores supplied water and drains the stored water downward.

[0441] The water supply structure 1440 includes a water reservoir 1441 disposed on the water supply path 109 for temporarily storing water, and a water supply port 1445 for discharging water from the water reservoir 1441 to the water tank 300 .

[0442] The water reservoir 1441 may be formed in a certain structure. In this embodiment, the water reservoir 1441 is formed by combining multiple structures.

[0443] The water reservoir 1441 may be formed in at least one of the upper housing 1410, the lower housing 1420, and the water supply cap 1430 disposed on the water supply passage 109. The water reservoir 1441 may be formed by combining at least one of the upper housing 1410, the lower housing 1420, and the water supply cap 1430 disposed on the water supply passage 109.

[0444] In this embodiment, the water reservoir 1441 is formed by combining the lower shell 1420 and the water supply cap 1430 .

[0445] The lower shell 1420 includes a water reservoir base 1442 and a water reservoir wall 1444 .

[0446] The water reservoir base 1442 and the water reservoir wall 1444 are formed in the lower inner frame 1422 .

[0447] The water reservoir base 1442 is arranged in a horizontal manner, and the humidification medium 55 is discharged on the upper side of the water reservoir base 1442. The water reservoir base 1442 is connected to the lower screen frame 1426.

[0448] The water reservoir wall 1444 is formed to protrude upward from the water reservoir base 1442. The lower housing opening 1425 is disposed inside the water reservoir wall 1444, and the humidification medium 55 is disposed outside the water reservoir wall 1444. The water supply cap 1430 is located inside the water reservoir wall 1444.

[0449] The water reservoir 1441 is formed between the inner side of the water reservoir wall 1444 , the upper side of the water reservoir base 1442 , and the outer side of the water supply cap 1430 .

[0450] The water reservoir base 1442 is formed with a water supply port 1445 , a clamping groove 1423 , and a coupling groove 1427 . The water supply port 1445 and the clamping groove 1423 are disposed on the inner side of the water reservoir wall 1444 , and the coupling groove 1427 is disposed on the outer side of the water reservoir wall 1444 .

[0451] The water supply port 1445 is formed in a slit shape. The water supply port 1445 is formed in an open state along the vertical direction. The water supply port 1445 is formed in an arc shape when viewed from above. The water supply port 1445 is formed along the inner side boundary of the water reservoir wall 1444.

[0452] The width of the slit used to form the water supply port 1445 is 0.7 to 0.8 mm, and the length thereof is not limited.

[0453] The water supply port 1445 is formed to have a wide upper cross section and a narrow lower cross section when viewed from the top and bottom. The cross section of the water supply port 1445 is formed to have a funnel shape with a pointed bottom when viewed from the top and bottom.

[0454] The water supply port 1445 can block the flow of air by virtue of such a cross-sectional shape and discharge water downward.

[0455] When the humidification and purification device is operating, air flows from the humidification flow path 106 to the discharge flow path 107, and a portion of the air can be discharged through the water supply port 1445. However, when water is stored in the water reservoir 1441, air is not discharged through the water supply port 1445. This is because the weight of the water stored in the water reservoir 1441 is greater than the pressure of the air.

[0456] When the cross section of the water supply port 1445 is formed to be wider, air may be expelled, and in this process, the water stored in the water reservoir 1441 may splash upward.

[0457] The water supply structure 1440 of this embodiment can prevent the water in the water reservoir 1441 from splashing in the opposite direction of the water supply even when water is supplied when the humidification and purification device is in operation.

[0458] Air can be prevented from being discharged from the water supply port 1445 by adjusting the capacity of the water reservoir 1441. For example, the pressure caused by the weight of the water stored in the water reservoir 1441 can be made greater than the wind pressure that can be discharged through the water supply port 1445.

[0459] At the same time, if the width of the slit-shaped water supply port 1445 is narrow, air can flow toward the discharge humidification medium 55 due to resistance. If the gap in the discharge humidification medium 55 is larger than the cross-sectional area of ​​the water supply port 1445, air will flow toward the discharge humidification medium 55, where resistance is less. On the other hand, if water is stored in the water reservoir 1441, the water is discharged through the water supply port 1445 under its own weight.

[0460] As described above, it is possible to prevent air from being discharged through the water supply port 1445 through various methods.

[0461] When a user supplies water to the top of water supply cap 1430, the supplied water is temporarily stored in water reservoir 1441. The water stored in water reservoir 1441 is drained downward through water supply port 1445. The water in water reservoir 1441 can be drained through coupling groove 1427 formed in water reservoir base 1442. The water in water reservoir 1441 can be drained through lower housing opening 1425.

[0462] When more water than the capacity of the water reservoir 1441 is supplied, the water may overflow over the water reservoir wall 1444. Even if the water overflows outside the water reservoir wall 1444, the supplied water will fall or flow toward the visual body 210. The water flowing along the visual body 210 will also be guided into the interior of the water tank 300.

[0463] The humidification and purification device of this embodiment has the advantage of being able to supply water to the water tank 300 regardless of its operating state.

[0464] In this embodiment, the humidifying medium housing 1400 is disposed below the top cover assembly 230. However, unlike this embodiment, the humidifying and purifying device can also be constructed without the top cover assembly 230. Specifically, the humidifying medium housing 1400, with the water supply cap 1430 disposed thereon, can be exposed to the outside, and water can be supplied from the top by pouring water into the water supply cap 1430.

[0465] The flow of water during upper water supply will be described in more detail below.

[0466] Water supplied from the upper portion falls downward through the top cover assembly 230 .

[0467] In this embodiment, the water falling from the top cover assembly 230 does not directly fall onto the water surface of the water tank 300 , but at least a portion of the water falls toward the upper portion of the watering housing 800 .

[0468] When the humidification and purification device is operating in the humidification mode (when the watering housing is rotating), water supplied from the upper portion falls into the watering housing 800 and scatters, thereby forming a rain scene.

[0469] When the humidification and purification device is stopped or operating in the purification mode (when the watering housing is stopped), water supplied from the upper portion flows along the watering housing 800 to the water tank 300 .

[0470] That is, regardless of the operating state of the humidification and purification device, it is possible to minimize the water supplied from the upper portion from directly falling onto the water surface of the water tank 300 , thereby minimizing the noise of falling water.

[0471] Due to the nature of water, some of the water supplied from above and flowing along the bottom surface of the discharge humidification medium housing 1400 can fall directly onto the water surface. However, this is only a small amount of water and contributes only a small portion to the overall noise. In particular, after a certain amount of water has fallen onto the bottom surface of the discharge humidification medium housing 1400, it is absorbed by the discharge humidification medium 55 through the air flow in the humidification flow path 106.

[0472] The water supplied from the upper portion falls toward the watering housing cover 860 of the watering housing 800 .

[0473] In order to allow water supplied from the upper portion to fall into the watering housing cover 860 , the diameter of the watering housing cover 860 is formed to be larger than the diameter of the water supply port 1445 .

[0474] The watering housing cover 860 is disposed below the water supply port 1445 , and is also disposed below the upper housing opening 1415 and the lower housing opening 1425 .

[0475] That is, most of the water supplied through the upper water supply falls to the watering housing cover 860 .

[0476] When the watering housing 800 rotates, water supplied from the upper portion is dispersed radially outward from the watering housing cover 860. To effectively disperse the water supplied from the upper portion, the watering housing cover 860 is formed with protrusions 861. Multiple protrusions 861 are arranged along the edge of the watering housing cover 860. The protrusions 861 protrude radially outward from the watering housing cover 860.

[0477] When the watering housing 800 rotates, the water supplied from the upper portion is separated into droplets at the protrusions 861 .

[0478] Liquid droplets separated from the protrusion 861 collide with the inner side surface of the visual body 210. To this end, the watering housing cover 860 is preferably arranged on the same horizontal line as at least a portion of the visual body 210. Considering that the scattered liquid droplets fall under the action of gravity, it is preferably located at the middle height of the visual body 210.

[0479] The protrusion 861 is located at a higher position than the second injection ports 412 and 413 .

[0480] Droplets flying from the protrusions 861 create a rain scene. This rain scene during top water supply allows the user to confirm that the water supply is operating normally. In addition to visually confirming top water supply through effects such as rain, the sound produced by the flying droplets colliding with the visual body 210 can also be used to confirm top water supply.

[0481] There is a difference between the sound of rain generated when water is supplied from above and the sound through the ejection port 410. The sound of rain generated when water is supplied from above is louder and irregular than the sound of rain generated by pumping water.

[0482] In addition, when water is supplied from the upper portion, droplets of various sizes are splashed on the watering housing cover 860 .

[0483] In the case of a large droplet, due to its own weight, it flies from the protrusion 861 to the inner side of the visible body 210. In the case of a large droplet, due to its own weight, it forms a relatively constant trajectory S1.

[0484] The trajectory S1 is different from the trajectory S3 of the water ejected from the ejection port 410 .

[0485] The trajectory S3 of the water ejected from the second ejection ports 412 and 413 is different from the trajectory S1 of the water scattered from the projection 861. The trajectory S1 is formed higher than the trajectory S3.

[0486] In the case of small liquid droplets, the liquid droplets are more affected by the air flow formed on the humidification flow path 106 than by their own weight.

[0487] Therefore, in the case of smaller droplets, they can float in the humidification flow path 106. Due to the influence of the wind pressure of the blower fan 24 and gravity, they will take on irregular trajectories.

[0488] In the case of smaller droplets, the droplets may be pulled near the watering housing 800 while floating on the humidification flow path 106 .

[0489] The watering wings 850 of the watering housing 800 can pull floating liquid droplets. The air flow based on the watering wings 850 pulls the floating or scattered liquid droplets toward the surface side of the watering housing 800.

[0490] The watering wings 850 can form a water film S2 by pulling the liquid droplets scattered from the watering housing cover 860. When water is supplied from above, the water film formed around the watering housing 800 can have different shapes depending on the amount of water supplied from above.

[0491] However, the water film has a characteristic of being formed symmetrically with respect to the watering housing 800 .

[0492] Figure 30 is a schematic diagram showing the flow of water inside the air cleaning module when water is supplied from the upper portion. Figure 31 is a schematic diagram showing the trajectory of water ejected through the 2-1st ejection port, Figure 32 is a schematic diagram showing the trajectory of water ejected through the 2-2 ejection port, Figure 33 is a schematic diagram showing the injection line.

[0493] The rain scene performed in the air cleaning module 200 is described in more detail.

[0494] The rain scene refers to the effect of rain outside the window. The rain scene refers to the effect of rain. In this embodiment, the effect of rain or rain is performed inside the visual body 210.

[0495] The watering wings 850, the first jet port 411, the 2-1 jet port 412, the 2-2 jet port 413, the watering housing cover 860, the protrusion 861, and the air flow of the blower fan 24 are the rain scene production units for generating the droplets.

[0496] The first jet port 411, the second-first jet port 412, and the second-second jet port 413 are used to jet pumped water in the watering unit 400. The water jetted from the first jet port 411, the second-first jet port 412, and the second-second jet port 413 creates a rain scene.

[0497] The watering housing cover 860 or the protrusion 861 creates a rain scene by scattering water dropped when water is supplied from the upper portion.

[0498] The sprayed or scattered liquid droplets can be crushed into smaller sizes based on the wind pressure or wind volume of the blower fan 24. As the air flowing through the blower unit 20 passes through the water tank humidification medium 51, the liquid droplets can be further miniaturized.

[0499] The air flowing through the air supply unit 20 can atomize the air falling from the humidification flow path 106. Since the air by the air supply unit 20 moves in the direction opposite to gravity, it collides with the air falling due to its own weight and the falling droplets, becoming atomized.

[0500] The liquid droplets generated by the rain scene performance unit can flow or float in the humidification flow path 106. The liquid droplets in the humidification flow path 106 can humidify the flowing air and form water droplets on the inner surface of the visual body 210.

[0501] The water droplets formed on the inner side of the visual body 210 may move along the inner side of the visual body 210 at an angle.

[0502] The visual body 210 is formed to be inclined toward the water tank 300. The visual body 210 is formed to be wider at the top and narrower at the bottom. This prolongs the retention time of liquid droplets flowing along the visual body 210, thereby extending the duration of the rain scene. Furthermore, the inclination of the visual body 210 can prevent the formed liquid droplets from flowing downward. The surface tension of the droplets helps the droplets remain formed on the visual body 210. Furthermore, the air flow from the air supply unit 20 can prevent the droplets from flowing downward.

[0503] Furthermore, a waterproof coating may be formed on the inner side of the visible body 210. When the waterproof coating is formed, the liquid droplets can be prevented from spreading widely and can be formed into a more round shape.

[0504] When water accumulates on the visual subject 210, the water accumulated on the visual subject 210 is projected or reflected onto the surface of the display 160. When the water accumulated on the visual subject 210 falls off, the display 160 will also present the same effect.

[0505] In the visual body 210, the actual droplets move along the slope from top to bottom and from outside to inside. The droplets reflected on the surface of the display 160 move from bottom to top and from outside to inside in the opposite direction of the display slope.

[0506] As a result, the actual droplets and the reflected droplets merge at the boundary where the visual subject 210 and the display 160 meet, which can help users perceive the rain scene more effectively.

[0507] Figure 34 This is a schematic diagram showing the position of the second injection port in the second embodiment of the present invention.

[0508] In this embodiment, unlike the first embodiment, three second injection ports are arranged.

[0509] The three second injection ports are arranged at intervals of 120 degrees and are composed of a 2-1 injection port 412 , a 2-2 injection port 413 , and a 2-3 injection port 414 .

[0510] Different from the first embodiment, the 2 - 3 injection port 414 may form a third injection line L3 .

[0511] The 2-3 spray port 414 may be disposed at a different height from the 2-1 spray port 412 or the 2-2 spray port 413. The 2-3 spray port 414 may overlap with the watering housing cover and form a wider spray angle.

[0512] The remaining structures are the same as those in the first embodiment, so detailed description will be omitted.

[0513] The preferred embodiments of the present invention are described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. Without departing from the technical concept of the present invention as claimed in the claims, a person skilled in the art can perform various modified implementations thereof. Such modified implementations should not be understood separately from the technical concept or prospects of the present invention.
