Description

humidifier

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

[0002] A humidifier is a device that supplies moisture-containing air into a room. Humidifiers are equipped with a water tank for storing water and are classified into ultrasonic, heated, natural evaporation, or hybrid types depending on the humidification method.

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

[0004] A water tank is placed inside the humidifier to store water. To extend the humidifier's operating time, the size of the water tank can be increased. Since a larger tank allows for a greater volume of water to be stored, the humidifier's operating time can be extended.

[0005] However, as the size of the water tank increases, the weight also increases, so a structure is required that can stably support the load of the tank and secure space for the humidification channel.

[0006] Furthermore, if water accumulates or moisture remains inside, cleanliness deteriorates, and there is a possibility that contaminated humidified air may be discharged. Therefore, internal hygiene management, such as for the humidification airflow path, is necessary.

[0007] In the prior art Korean published patent KR 10-2022-0080870 A, a heated humidifier device is disclosed that increases safety by lowering the humidification flow temperature during heated humidification. However, in the prior art, the water tank is directly connected only to the supply pipe that supplies water, and there is no structure to support the water tank with a heavy load.

[0008] When constructing a structure to support the water tank, the humidification channel may be blocked more than necessary. In this case, the resistance of the humidification channel increases, and the humidification flow rate may decrease.

[0009] In addition, if heat transfer is obstructed due to the structure supporting the water tank, the performance of the sterilization function using heating may be degraded.

[0010] The present disclosure aims to solve the aforementioned problems and other problems.

[0011] The object of the present disclosure is to provide a humidifier capable of stably supporting a water tank.

[0156] FIG. 8 is an exploded perspective view of a water tank and an inner shell according to one embodiment of the present disclosure.

[0157] Referring to FIG. 8, the humidifier includes a water tank (100) forming a space for storing water, and an inner shell (180) forming a space for the water tank (100).

[0158] The humidification module is positioned below the inner shell (160) and can generate humidified air with water supplied from the water tank (100).

[0159] The water tank (100) includes an outer water tank (160) and an inner water tank (102) disposed inside the outer water tank (160). The water tank (100) includes an inner water tank (102) and an outer water tank (160) disposed outside the inner water tank. The inner water tank (102) forms a space in which water is stored. The outer water tank (160) forms a space in which the inner water tank (102) is accommodated. The inner water tank (102) may be disposed such that its outer perimeter surface contacts the inner perimeter surface of the outer water tank (160).

[0160] FIG. 9 is a perspective view of an outer tank according to one embodiment of the present disclosure.

[0161] The outer tank (160) may include a lower wall (908) and a perimeter wall (907) that extends upward from the lower wall (908) to form an internal space.

[0162] The outer tank (160) has a through hole (902a) formed in its lower surface through which the connector (120) passes. The through hole (902a) can be formed in the center of the lower wall (908).

[0163] The outer tank (160) includes a lower rim (902) that protrudes downward from the lower surface. The lower rim (902) has a structure that protrudes downward from the circumference of the through hole (902a). The lower rim (902) may have a ring-shaped structure.

A portion of the connector (120) is positioned inside the inner water tank (102). The remainder of the connector (120) is positioned outside the inner water tank (102).

[0165] The connector (120) can send water stored in the inner water tank (102) to the humidification module. The connector (120) can send water stored in the inner water tank (102) to the humidification module through the supply pipe (230).

[0166]

[0167] The inner shell (180) is positioned spaced apart from the water tank (100). A first discharge channel (32) through which humidified air flows is formed between the inner shell (180) and the outer water tank (160). A first discharge channel (32) through which humidified air flows is formed between the water tank (100) and the inner shell (180).

[0168] More specifically, the first discharge channel (32) can be formed between the inner shell (180) and the outer tank (160). The space between the inner shell (180) and the outer tank (160) serves as a humidification channel through which humidification flow flows.

[0169] The combined structure of the inner shell (180) and the outer tank (160) affects the humidification performance by influencing the flow of the humidification fluid, and also affects the internal temperature of the humidification fluid to increase or decrease the sterilization performance.

[0170] The inner shell (180) and outer tank (160) combined structure according to an embodiment of the present disclosure is shaped to stably support the tank (100) and allow humidification flow to flow smoothly, thereby securing maximum humidification and sterilization performance. Through a structure that stably maintains the tank, the size of the usable tank can be increased and humidification performance can be increased.

[0171] The inner shell (180) and outer tank (160) combined structure according to an embodiment of the present disclosure includes a rib structure spaced apart from each other between the bottom of the tank (100) and the inner shell (180). The rib structure may extend from the inner shell (180) or the outer tank (160).

[0172] The rib structure can be arranged in a symmetrical structure. The rib structure can be arranged symmetrically with respect to the center of the inner shell (180). The rib structure can be arranged symmetrically with respect to the center of the outer tank (160).

[0173] FIG. 10 is a plan view of an inner shell according to one embodiment of the present disclosure, illustrating an inner shell (180a) having a plurality of inner ribs (1000) formed therein.

[0174] FIG. 10 is a plan view of the inner shell (180a) when viewed from above, and the inner bottom surface (801) of the inner shell (180a) is disclosed.

[0175] A plurality of inner ribs (1000) are arranged between the bottom of the tank (100) and the inner shell (180). The plurality of inner ribs (1000) are arranged spaced apart in the circumferential direction.

[0176] Referring to FIG. 10, a plurality of inner ribs (1000) are arranged spaced apart in the circumferential direction between the bottom of the outer tank (160) and the inner shell (180).

[0177] At the bottom of the inner shell (180a), a shell penetration hole (184) through which a part of the connector (120) passes, and an exhaust connection pipe (192) through which humidification flow is sucked in from the humidification module are arranged. The humidified air discharged from the humidification module passes through the exhaust connection pipe (192) and is supplied to the first discharge path (32).

[0178] According to an embodiment of the present disclosure, a rib structure exists between the inner shell (180) and the outer tank (160) to maintain a constant distance between the two structures and to stably position the outer tank (160).

[0179] Referring to FIG. 10, an outer tank (160) that protrudes upward from the bottom of the inner shell (180) and is combined with an inner tank (102) is placed on the inner shell (180a). A plurality of inner ribs (1000) protrude upward from the bottom surface (801) of the inner shell (180a) to evenly support the load of the tank (100). Accordingly, the tank (100) filled with water can be stably supported.

[0180] A plurality of inner ribs (1000) may protrude upward from the bottom surface (801) of the inner shell (180a) facing the outer tank (160) and may come into contact with the bottom of the outer tank (160).

[0181] Alternatively, a plurality of inner ribs (1000) may be configured to protrude downward from the bottom of the outer tank (160) and come into contact with the inner shell (180). An embodiment in which the rib structure is formed in the outer tank (160) will be described later with reference to FIG. 18, etc.

[0182] Multiple inner ribs (1000) can be arranged symmetrically around the shell penetration hole (184).

[0183] Multiple inner ribs (1000) are spaced apart from each other to secure a humidification path and to allow heated air to pass through and sterilize the humidification path.

[0184] The humidifier of the present disclosure generates humidified air by heating water. By generating humidified air using heated water, clean and pleasant humidified air can be provided.

[0185] In this case, the humidifier uses high-temperature water not only to generate clean humidified air but also to sterilize the internal air passages. By heating the water and using it to sterilize the air passages, the passages can be kept clean.

[0186] The humidifier can provide a sterilization operation mode in which high power is applied to the first humidification tank (300) to raise the temperature inside the humidification water path to a temperature higher than a preset high temperature, thereby performing heat sterilization.

[0187] Meanwhile, if a blind spot in heat sterilization occurs within the humidification path, the performance of the heat sterilization function may be degraded.

[0188] A plurality of inner ribs (1000) are arranged lengthwise in the circumferential direction. In the rib structure of the present disclosure, the inner ribs (1000) are arranged lengthwise in the circumferential direction along the flow of the entire flow path (flow of fluid).

[0189] Multiple inner ribs (1000) can be arranged symmetrically on the left and right sides with respect to the exhaust connection pipe (192) to form a uniform air flow without blind spots. Multiple inner ribs (1000a, 1000b) can be arranged symmetrically on the left side (1000a) and the right side (1000b), respectively.

[0190] First inner ribs (1000a) may be arranged on one side of the exhaust connection pipe (192), and second inner ribs (1000b) may be arranged on the other side of the exhaust connection pipe (192).

[0191] First inner ribs (1000a) may be disposed on one side of the shell penetration hole (184), and second inner ribs (1000b) may be disposed on the other side of the shell penetration hole (184).

[0192] Because it is a symmetrical structure, the spacing between the first inner ribs (1000a) may be the same as the spacing between the second inner ribs (1000b). The internal spacing between the ribs included in the first inner ribs (1000a) and the internal spacing between the ribs included in the second inner ribs (1000b) may be the same.

[0193] The spacing between the first inner ribs (1000a) and the second inner ribs (1000b) may be larger than the internal spacing of each inner rib (1000a, 1000b). That is, the spacing between the first inner ribs (1000a) may be smaller than the spacing between the first inner ribs (1000a) and the second inner ribs (1000b). Also, the spacing between the second inner ribs (1000b) may be smaller than the spacing between the first inner ribs (1000a) and the second inner ribs (1000b).

[0194] The inner ribs (1000a, 1000b) are each composed of multiple ribs rather than a single rib, creating an opening in the middle of the inner ribs (1000a, 1000b) through which heat flow can spread. Accordingly, heat flow can spread uniformly in the humidification path, and the path can be heated and sterilized by the heat of the humidification flow without any blind spots.

[0195] FIG. 11 is a side view of a structure in which an outer tank and an inner shell are combined according to one embodiment of the present disclosure, and FIG. 12 is an enlarged view of the combined portion (ZA) of the outer tank and the inner shell of FIG. 11.

[0196] Referring to FIGS. 10 to 12, a plurality of inner ribs (1000a, 1000b) are formed in a shape protruding upward from the bottom surface (801) of the inner shell (180a).

[0197] For example, four inner ribs (1000a, 1000b) are protruded upward from the bottom (801) of the inner shell (180a). A first inner rib (1000a) consisting of two ribs is placed on the left side, and a second inner rib (1000b) consisting of two ribs is placed on the right side.

[0198] The outer tank (160) is placed on top of the inner rib (1000a, 1000b) structure of the inner shell (180a).

[0199] The inner rib (1000a, 1000b) structure basically supports the load of the inner tank (102) (combined with the outer tank (160)) evenly and allows the inner tank (102) combined with the outer tank (160) to be stably positioned.

[0200] An outer tank (160) is placed on an inner rib (1000a, 1000b) protruding from an inner shell (180a), and a humidification path is formed through which mist passes between the inner shell (180a) and the outer tank (160).

[0201] By stably positioning the outer tank (160) and the inner tank (102) in the inner shell (180a), the spacing of the humidification path through which mist passes between the outer tank (160) and the inner shell (180) is maintained, thereby enabling consistent humidification performance and mist shape.

[0202] Multiple inner ribs (1000) are arranged in a long circumferential direction along the flow of the entire Euro (flow of fluid).

[0203] FIG. 13 is a drawing showing an inner rib and an air flow direction according to one embodiment of the present disclosure.

[0204] Referring to FIG. 13, the arrangement direction (1310) and the air flow direction (1320) of the inner rib (100) can both be formed in the circumferential direction.

[0205] Through this, the waterway can be heated and sterilized by the heat of the humidification flow without any blind spots within the humidification waterway.

[0206] FIGS. 14a and FIGS. 14b are drawings referenced in the explanation of air flow and sterilization according to the inner rib structure.

[0207] FIG. 14a illustrates a case (1400) composed of a single rib rather than multiple ribs on one side (left or right).

[0208] Referring to FIG. 14a, due to the structure in which one rib (1400) is arranged in a long shape, the flow of heating humidification cannot pass over the outer surface of the rib (1400).

[0209] In the case where it is composed of a single rib (1400) on one side, heat flow cannot pass outside the rib (1400) and the temperature cannot rise to a certain temperature, so a weak point (or blind spot) (1410) of the heat sterilization path may occur.

[0210] FIG. 14b illustrates a case where multiple ribs (1000) are arranged on each side (left or right).

[0211] Referring to FIG. 14b, instead of a single rib in the circumferential direction, multiple ribs are formed to create a kind of opening between the ribs (1000).

[0212] Referring to FIG. 14b, in addition to the main flow (1320) in the circumferential direction, a flow (1420) passing between the ribs (1000) is generated so that heat flow can also be transferred outside the ribs (1000).

[0213] FIG. 15 is a diagram showing the temperature measurement results according to the inner rib structure, illustrating the temperatures measured at three temperature measurement points (SP1, SP2, SP3) indicated in FIG. 14.

[0214] The first temperature result at each point is the temperature measurement result of the relatively weak first intensity sterilization mode when configured with a single rib on one side as in Fig. 14a.

[0215] The second temperature result at each point is the temperature measurement result of the relatively strong second-intensity sterilization mode when configured with a single rib on one side as in Fig. 14a.

[0216] The third temperature result of each point is the temperature measurement result of the first-century sterilization mode when composed of multiple ribs on one side as shown in Fig. 14b.

[0217] The fourth temperature result of each point is the temperature measurement result of the sterilization mode of the second century when composed of multiple ribs on one side as shown in Fig. 14b.

[0218] Referring to Fig. 15, it can be seen that when a multiple rib structure is applied, the temperature is measured to be 60 degrees or higher, which is effective for sterilization.

[0219] The inner ribs (1000a, 1000b) may each include two or more ribs. For example, each inner rib (1000a, 1000b) may each include two or three ribs.

[0220] In another embodiment, the inner ribs (1000a, 1000b) may each include a connecting portion connecting two or more ribs and an opening above the connecting portion.

[0221] In another embodiment, the inner ribs (1000a, 1000b) may each include a connecting portion connecting two or more ribs and an opening between the connecting portions.

[0222] FIG. 16 is a drawing illustrating various shapes of an inner rib according to an embodiment of the present disclosure.

[0223] FIG. 16 (a) illustrates a case composed of two ribs (1611, 1612) based on one side (left or right). The two ribs (1611, 1612) may each extend from one side (1610) of the inner shell (180) or outer tank (160).

[0224] FIG. 16(b) illustrates a case composed of three ribs (1621, 1622, 1623) based on one side (left or right). The three ribs (1621, 1622, 1623) may each extend from one side (1620) of the inner shell (180) or outer tank (160).

[0225] FIG. 16 (c) illustrates a case where only a portion of the opening (1631) is formed between the reference ribs (1630) on one side (left or right). The ribs (1630) may include an opening (1631) that is open upward.

[0226] FIG. 16 (d) illustrates a case where a hole (1641) is machined in the center of a one-sided (left or right) reference rib (1640). Multiple holes (1641) may be formed inside the rib (1640).

[0227] Meanwhile, it is preferable that a plurality of inner ribs (1000) be arranged to contact the curved bottom edge of the outer tank (160).

[0228] FIGS. 17a and FIGS. 17b are drawings referenced in the description regarding the position of the inner rib.

[0229] Referring to FIG. 17a, the inner rib (1710) can be positioned to be in contact with the bottom surface of the outer tank (160). In this case, the outer tank (160) can be shaken from side to side.

[0230] Referring to FIG. 17b, the inner rib (1710) is positioned to be in contact with the curved bottom edge of the outer tank (160), so that the outer tank (160) can be fixed without being pushed left or right and shaking.

[0231] In addition, since a symmetrical structure is applied within the humidification channel for uniform mist discharge, the ribs will be placed in the same position symmetrically on both sides. Therefore, although only the right side is illustrated in FIG. 17a and FIG. 17b, the same will be applied to the left side.

[0232] FIG. 18 is a plan view of an outer tank according to one embodiment of the present disclosure, in which the lower surface (908) of the outer tank (160a) is disclosed as a plan view when the outer tank (160a) is viewed from below.

[0233] FIG. 19 is a side view of a structure in which an outer tank and an inner shell are combined according to one embodiment of the present disclosure, and FIG. 20 is an enlarged view of the combined portion (ZB) of the outer tank and the inner shell of FIG. 19.

[0234] FIGS. 18 to 20 show that a plurality of inner ribs (1800) are formed in the outer tank (160a). A plurality of inner ribs (1800) protrude downward from the lower end of the outer tank (160a).

[0235] As shown in FIG. 10, FIG. 18, etc., the part to which the rib (1000, 1800) is applied may be an inner shell (180) or an outer tank (160).

[0236] A plurality of inner ribs (1800) protrude downward from the bottom of the outer tank (160a) and can come into contact with the inner shell (180).

[0237] FIGS. 18 to 20 differ from the inner rib (1000) described above only in that the inner rib (1800) is formed in an outer tank (160a), but other features can be applied identically.

[0238] The outer tank (160) may include a lower wall (908) and a perimeter wall (907) that extends upward from the lower wall (908) to form an internal space.

[0239] The outer tank (160) has a through hole (902a) formed in its lower surface through which the connector (120) passes. The through hole (902a) can be formed in the center of the lower wall (908).

[0240] Multiple inner ribs (1800) can be arranged symmetrically around the through hole (902a) of the outer tank (160).

[0241] A plurality of inner ribs (1800) protrude from the curved bottom edge of the outer tank (160) and contact the lower inner shell (180), thereby supporting the tank (100) more stably.

[0242] A plurality of inner ribs (1800) may include third inner ribs (1800a) disposed on one side of the through hole (902a) and fourth inner ribs (1800b) disposed on the other side of the through hole (902a).

[0243] Because it is a symmetrical structure, the spacing between the third inner ribs (1800a) may be the same as the spacing between the fourth inner ribs (1800b). The internal spacing between the ribs included in the third inner ribs (1800a) and the internal spacing between the ribs included in the fourth inner ribs (1800b) may be the same.

[0244] The spacing between the third inner ribs (1800a) and the fourth inner ribs (1800b) may be larger than the internal spacing of each inner rib (1800a, 1800b). That is, the spacing between the third inner ribs (1800a) may be smaller than the spacing between the third inner ribs (1800a) and the fourth inner ribs (1800b). Also, the spacing between the fourth inner ribs (1800b) may be smaller than the spacing between the third inner ribs (1800a) and the fourth inner ribs (1800b).

[0245] According to the present disclosure, by applying a rib structure (1000, 1800) that protrudes from the inner shell (180) or outer tank (160) and makes line contact with the counterpart, the tank (100) can be supported while minimizing the effect on the humidification flow.

[0246] FIGS. 21 and FIGS. 22 are drawings referenced in the description of an inner shell (180b) including a support portion according to one embodiment of the present disclosure.

[0247] Referring to FIGS. 21 and 22, a plurality of support members (1000) (1000c, 1000d) with increased contact area are arranged between the bottom of the outer tank (160) and the inner shell (180b).

[0248] A plurality of support members (1000c, 1000d) with increased contact area can be placed between the inner shell (180) and the outer tank (160). The support members (1000c, 1000d) can support the tank (100) more stably by making surface contact with each of the inner shell (180) and the outer tank (160) over a wider area.

[0249] The upper surface of the plurality of support members (1000c, 1000d) can be in surface contact with the outer tank (160). Additionally, the lower surface of the plurality of support members (1000c, 1000d) can be in surface contact with the inner shell (180b).

[0250] Multiple support members (1000c, 1000d) are spaced apart in the circumferential direction. At the bottom of the inner shell (180b), a shell penetration hole (184) through which a part of the connector (120) passes, and an exhaust connection pipe (192) through which humidification flow is sucked from the humidification module are arranged.

[0251] Multiple support members (1000c, 1000d) maintain a constant distance between the inner shell (180b) and the outer tank (160) and stably support the outer tank (160).

[0252] Referring to FIGS. 21 and 22, an outer tank (160) that protrudes upward from the bottom of the inner shell (180b) and is combined with the inner tank (102) is placed on the inner shell (180b). A plurality of support members (1000c, 1000d) protrude upward from the bottom surface (801) of the inner shell (180b) to evenly support the load of the tank (100). Accordingly, the tank (100) filled with water can be stably supported.

[0253] A plurality of support members (1000c, 1000d) may protrude upward from the bottom surface (801) of the inner shell (180b) facing the outer tank (160) and may come into contact with the bottom of the outer tank (160).

[0254] FIGS. 23 and FIGS. 24 are drawings referenced in the description of an outer tank including a support member according to one embodiment of the present disclosure.

[0255] Referring to FIGS. 23 and 24, a plurality of support members (1800) (1800c, 1800d) with increased contact area are arranged between the bottom of the outer tank (160b) and the inner shell (180).

[0256] The outer tank (160b) may include a lower wall (908) and a perimeter wall (907) that extends upward from the lower wall (908) to form an internal space.

[0257] The outer tank (160b) has a through hole (902a) formed in its lower surface through which the connector (120) passes. The through hole (902a) can be formed in the center of the lower wall (908).

[0258] Multiple support members (1800c, 1800d) can be arranged symmetrically around the through hole (902a) of the outer tank (160b).

[0259] In order to prevent the outer tank (160) from shaking left and right, a plurality of support members (1800c, 1800d) protrude from the curved bottom edge of the outer tank (160b) and can come into contact with the inner shell (180) on the lower side.

[0260] Multiple support members (1800a, 1800b, 1800c, 1800d) can be arranged in a circumferential direction along the flow of the entire flow path (flow of fluid).

[0261] A plurality of support members (1800a, 1800b, 1800c, 1800d) are arranged symmetrically on the left and right sides to evenly distribute the load.

[0262] In order for humidification flow to flow well along the support members (1800a, 1800b, 1800c, 1800d), some of the support members (1800a, 1800b, 1800c, 1800d) may have a streamlined structure. In terms of air flow, the front and rear directions of the multiple support members (1800a, 1800b, 1800c, 1800d) may have a streamlined shape, thereby minimizing flow resistance.

[0263] According to one embodiment of the present disclosure, a protrusion (2500) supporting a support portion (1800a, 1800b, 1800c, 1800d) may be further included.

[0264] The protrusion (2500) may be located between the inner shell (180) and the outer tank (160). The protrusion (2500) may protrude upward from the inner shell (180).

[0265] The protrusion (2500) can contact one side of the support portion (1800a, 1800b, 1800c, 1800d) to prevent left-right shaking of the outer tank (160). Preferably, the protrusion (2500) can contact the outer side of the support portion (1800a, 1800b, 1800c, 1800d).

[0266] FIGS. 25 and FIGS. 26 are drawings referenced in the description of a protrusion supporting a support member according to one embodiment of the present disclosure.

[0267] FIG. 25 illustrates an inner shell (180c) with a protrusion (2500) formed therein, and FIG. 26 illustrates an enlarged view of the connection between the inner shell (180c) and the outer tank (160b).

[0268] The protrusion (2500) may be located between the inner shell (180c) and the outer tank (160b). The protrusion (2500) may protrude upward from the inner shell (180c).

[0269] The protrusion (2500) can contact the outer side of the support portion (1800c, 1800d) to prevent left-right shaking of the outer tank (160b). Preferably, the protrusion (2500) can contact the outer side of the support portion (1800a, 1800b, 1800c, 1800d).

[0270] Although preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications can be made by those skilled in the art without departing from the gist of the present disclosure as claimed in the patent claims.
