The air that has risen to the z1 side in the ascending tube section 35 travels to the descending tube section 51 through a plurality of openings 351. In the descending tube section 51, the air is turned back in its travel direction and descends toward the z2 side in the z direction. This air reaches the third storage section 33 while being partially guided by the partition section 44.
[0059] [Second air path forming part 8B] The second air passage forming section 8B is a section where an air passage is formed in which the air from the first air passage forming section 8A and at least one of the steam and the mist generated by the humidifier section 6 are mixed and flow toward the z1 side in the z direction (upward) and are guided to the air outlet 54. The specific configuration of the second air passage forming section 8B is not limited in any way, and it may be formed of a single member or a dedicated member, or may be formed of a plurality of members. In this embodiment, the second air passage forming section 8B is formed to include the above-mentioned inner tubular section 45 and outer tubular section 53, as shown in Figs. 4, 5, and 12.
[0060] In this embodiment, the second air passage forming section 8B is disposed at a position (downwind position) shifted toward the x1 side in the x direction with respect to the mist generating section 63 and the third storage section 33. The tapered opening 46 is disposed directly above the mist generating section 63 on the z1 side in the z direction. However, the portion of the second air passage forming section 8B on the z1 side in the z direction is adjacent to the third storage section 33 so as to share a space. With such an arrangement, for example, water droplets that have fallen from the tapered opening 46 can be reliably collected by the mist generating section 63, and mist can be generated using these water droplets. In addition, this mist is quickly guided to the second air passage forming section 8B adjacent to the mist generating section 63.
[0061] The air from the first air passage forming section 8A becomes mixed air and flows into the inner cylinder section 45 from the z2 side in the z direction via the third storage section 33. This mixed air rises to the z1 side in the z direction inside the inner cylinder section 45, and flows into the outer cylinder section 53 from the z2 side in the z direction through the opening 451. Then, the mixed air that has risen to the z1 side in the z direction inside the outer cylinder section 53 is blown out from the blowing outlet 54 located at the upper end of the outer cylinder section 53 to the outside. Since the second air passage forming section 8B extends linearly upward in the z direction, the mixed air is likely to flow linearly. Therefore, unlike the present embodiment, in this embodiment, the mixed air is less likely to collide with the wall surface of the second air passage forming section 8B and water droplets are less likely to adhere to the wall surface compared to the case where the air passage is curved. As a result, it is possible to suppress a decrease in the amount of humidification.
[0062] [Control unit 91] The control unit 91 controls each part of the humidifier A1, and is constituted by, for example, a CPU. An example of the control by the control unit 91 is heating control of the heating unit 62. When a temperature sensor (not shown) is provided in the third storage unit 33 as described above, the heating state of the heating unit 62 may be controlled based on the water temperature measured by the temperature sensor. Specifically, if the water temperature in the third storage unit 33 is too high, it may induce a malfunction of the mist generating unit 63. On the other hand, if the water temperature drops too much, the amount of humidification in the humidifying unit 6 will be insufficient. For this reason, it is preferable to control the heating unit 62 so that the water temperature in the third storage unit 33 is less than 100°C (for example, about 50°C).
[0063] Another example of control by the control unit 91 is controlling the humidification state of the humidifier unit 6 according to the humidity of the sucked air measured by the temperature and humidity sensor 94. When the humidity measured by the temperature and humidity sensor 94 is low, it is assumed that the air outside the humidifier A1 is dry. For this reason, the humidifier unit 6 is controlled so as to increase the amount of humidification by the humidifier unit 6. On the other hand, when the humidity measured by the temperature and humidity sensor 94 is high, it is assumed that the air outside the humidifier A1 is moist. For this reason, control is performed to keep the amount of humidification by the humidifier unit 6 low or to stop the operation of the humidifier unit 6.
[0064] It is preferable that the control unit 91 controls the humidifier unit 6 by adjusting both the heating state of the heating unit 62 and the amount of mist generated by the mist generating unit 63. Adjusting only one of them may result in the temperature of air blown from the air outlet 54 not being appropriately controlled, which may cause problems such as a wet floor.
[0065] [Display section 92] The display unit 92 displays the operating state of the humidifier A1 and is exposed to the outside, for example, from the side panel 14. The display unit 92 is, for example, a liquid crystal panel or an organic EL panel. The display unit 92 may also serve as an operation unit for the humidifier A1 by including a touch sensor or the like.
[0066] [Power cord 93] The power cord 93 is for receiving the power necessary for the operation of the humidifier A1. The power cord 93 is designed to be plugged into, for example, a commercial 100V power outlet.
[0067] Next, an example of the operation of the humidifier A1 will be described.
[0068] As shown in Figs. 5 and 6, water supplied from tank 2 is stored in first storage section 31. Next, water flows from first storage section 31 into second storage section 32 and third storage section 33. As shown in Figs. 5 and 7 to 10, in second storage section 32, water is heated by heating section 62. This causes the water to evaporate and generate steam. As shown in Fig. 8, the steam generated in second storage section 32 enters third shell section 43 through connection section 47.
[0069] 8, 11, and 12, in third storage section 33, mist is generated in mist generating section 63. Next, the air, steam, and mist that have flowed through first air passage forming section 8A are mixed in third storage section 33 and third shell section 43. Then, the mixed air obtained by mixing these is blown out from outlet 54 through second air passage forming section 8B.
[0070] Next, the operation of the humidifier A1 will be described.
[0071] According to this embodiment, as shown in FIG. 9, the air that passes through the opening 122 and is guided to the heating unit 62 side is heated by the heating unit 62 (rear surface portion 622), and then is sucked in by the blower 7 and discharged to the first air passage forming unit 8A. The air that passes through the first air passage forming unit 8A becomes mixed air containing steam and mist, and is blown out of the outlet 54 through the second air passage forming unit 8B. This makes it possible to further increase the temperature of the air that constitutes the mixed air. This allows the moisture contained in the mixed air blown out of the outlet 54 to evaporate more quickly outside the humidifier A1. This makes it possible to prevent the installation location of the humidifier A1 from getting wet due to falling water droplets. In addition, by guiding the air from the opening 122 to the heating unit 62, it is possible to prevent the heating unit 62 and the vicinity of the heating unit 62 from being thermally damaged due to overheating.
[0072] The cross-sectional area of the air outlet 54 is smaller than the cross-sectional area of the outer tubular portion 53 constituting the second air-passage forming portion 8B. This makes it possible to improve the air blowing speed from the air outlet 54, and further suppresses water droplets from falling around the humidifier A1.
[0073] As shown in Fig. 12, the mixed air is blown out from outlet 54 at an angle α with respect to top surface 131. Also, as shown in Figs. 1 and 2, the blowing direction from outlet 54 is the opposite side to inlet 151 in the x direction. Therefore, it is possible to prevent the mixed air from outlet 54 from being sucked in through inlet 151, which is preferable for controlling the amount of humidification based on the actual environmental humidity around humidifier A1.
[0074] Furthermore, by setting the angle α of the air blown out from the air outlet 54 to 30° or more and less than 60°, the mixed air can be distributed over an appropriate height range in the z direction and an appropriate range in the x direction. If the angle α is 40° or more and 50° or less, the mixed air can be blown out to a more preferable range.
[0075] The blower unit 7 being a sirocco fan has the advantage of being able to reduce noise in the surroundings even when a large amount of air is set to be blown out from the air outlet 54. In addition, the sirocco fan has the advantage of being applicable even to air paths with high static pressure and large pressure loss.
[0076] <Second embodiment> 13 and 14 show a humidifier according to a second embodiment of the present invention. The humidifier A2 of this embodiment further includes an auxiliary blower section 7A.
[0077] The auxiliary blower 7A blows air drawn in from the suction port 151 towards the heating section 62 from the opposite side to the pool 61 (second storage section 32). The auxiliary blower 7A is disposed on the z2 side in the z direction with respect to the heating section 62, and faces the back surface section 622 of the heating section 62. The auxiliary blower 7A of the present embodiment discharges air drawn in from the z2 side (opening 122) in the z direction to the z1 side in the z direction, and is configured to include, for example, a propeller fan.
[0078] In this embodiment, the air blowing unit 7 blows out air that is sent out from the auxiliary air blowing unit 7A and heated by the heating unit 62. The air discharged from the auxiliary air blowing unit 7A is blown against the back surface 622 of the heating unit 62. As a result, the air is heated by the back surface 622 of the heating unit 62. The heated air is sucked into the second air blowing unit 7B and discharged toward the z1 side in the z direction.
[0079] This embodiment also makes it possible to prevent the installation location of the humidifier A1 from getting wet due to falling water droplets, and to prevent the heating unit 62 and the vicinity of the heating unit 62 from being thermally damaged due to overheating. Furthermore, by providing the auxiliary blower 7A, it is possible to guide a larger volume of air to the heating unit 62 side. This is preferable for preventing water droplets from falling and overheating of the heating unit 62, etc.
[0080] Since the auxiliary blower section 7A is a propeller fan, it is possible to send a larger amount of air toward the heating section 62. This makes it possible to remove more heat from the heating section 62 by the air.
[0081] <Third embodiment> 15 to 20 show a humidifier A3 according to a third embodiment of the present invention.
[0082] 15 and 16, in this embodiment, the bottom 12 has a first opening 1221, a second opening 1222, and a second opening 1223. The first opening 1221, the second opening 1222, and the second opening 1223 are located on the z2 side (lower side) in the z direction with respect to the heating unit 62. The first opening 1221, the second opening 1222, and the second opening 1223 each open in the z direction and are disposed apart from each other.
[0083] The center 620 shown in FIG. 16 is the center of the heating unit 62 as viewed from the z direction. The first opening 1221 is located on the side farther from the blower 7 than the center 620 (the x2 side in the x direction). The second opening 1222 is located on the side closer to the blower 7 than the center 620 (the x1 side in the x direction). In the illustrated example, the first opening 1221, the second opening 1222, and the blower 7 are aligned in the x direction. The second opening 1223 is located on the side closer to the blower 7 than the center 620 (the x1 side in the x direction). In the illustrated example, the second opening 1223 is located on the y2 side in the y direction with respect to the first opening 1221, the second opening 1222, and the blower 7. The positions of the second opening 1222 and the second opening 1223 in the x direction are approximately the same.
[0084] As shown in FIGS. 16 to 19, the humidifier A3 includes a heater support member 641, a temperature sensor 642, a temperature sensor 643, and a sensor support member 644.
[0085] The heater support member 641 supports the heating unit 62 from the z2 side (below) in the z direction, and fixes the heating unit 62 to the lower structure 3. In this embodiment, the heater support member 641 is attached to the lower structure 3 together with the heating unit 62 by a plurality of screws 649. The material of the heater support member 641 is not limited in any way, and resin, metal, etc. are appropriately selected. In this embodiment, the material of the heater support member 641 is resin.
[0086] As shown in Fig. 18 and Fig. 19, the heater support member 641 has a flat portion 6411, an opening 6412, a pair of clamping portions 6413, a pair of clamping portions 6414, a pair of clamping portions 6415, and a pair of clamping portions 6416. The flat portion 6411 is a portion that occupies most of the portion extending along the xy plane, and overlaps with almost the entire heating portion 62 when viewed from the z direction. The opening 6412 penetrates the flat portion 6411 in the z direction, and connects the z1 side and the z2 side of the flat portion 6411 in the z direction. In the illustrated example, the opening 6412 is provided at a position that overlaps with the center of the flat portion 6411 in the x direction and the y direction, and has a shape that extends long in the y direction.
[0087] The pair of clamping parts 6413, the pair of clamping parts 6414, the pair of clamping parts 6415, and the pair of clamping parts 6416 are for more reliably fixing the temperature sensor 642 and the temperature sensor 643 at desired positions. The pair of clamping parts 6413, the pair of clamping parts 6414, the pair of clamping parts 6415, and the pair of clamping parts 6416 each protrude from the flat part 6411 to the z2 side in the z direction. The pair of clamping parts 6413 and the pair of clamping parts 6415 are disposed on the y2 side in the y direction with respect to the opening 6412. The pair of clamping parts 6414 and the pair of clamping parts 6416 are disposed on the y1 side in the y direction with respect to the opening 6412. The pair of clamping parts 6413 and the pair of clamping parts 6414 are located at the same position in the x direction. The pair of clamping parts 6415 and the pair of clamping parts 6416 are located at the same position in the x direction.
[0088] The shapes, sizes, etc. of the pair of clamping parts 6413, the pair of clamping parts 6414, the pair of clamping parts 6415, and the pair of clamping parts 6416 may be the same or different from each other. In the illustrated example, the interval between the pair of clamping parts 6413 and the interval between the pair of clamping parts 6414 are narrower than the interval between the pair of clamping parts 6415 and the interval between the pair of clamping parts 6416, and the rest of the configuration is the same.
[0089] A specific configuration will be described using the pair of clamping portions 6413 as an example. The pair of clamping portions 6413 are spaced apart from each other in the x direction. Each of the pair of clamping portions 6413 has a protrusion 6417. The protrusions 6417 protrude toward the side where the pair of clamping portions 6413 face each other (inner side in the x direction), and are located at the same position in the y direction.
[0090] The temperature sensor 642 and the temperature sensor 643 detect the temperature of the heating unit 62 and perform a predetermined function according to the temperature of the heating unit 62. The type and number of the heating unit 624 and the temperature sensor 643 are not limited in any way. The configuration may include only one of the temperature sensor 642 and the temperature sensor 643, or may include one or more additional temperature sensors. In this embodiment, the temperature sensor 642 is a thermistor, and the temperature sensor 643 is a thermal fuse. In Figs. 16 to 19, the temperature sensors 642 and 643 are shown as being fixed near the heating unit 62, and other parts are omitted.
[0091] A part of the temperature sensor 642 enters the opening 6412, and as shown in FIG. 19(b), this part is close to the back surface 622 of the heating unit 62. In this embodiment, the temperature sensor 642 is covered by a protective tube 6421. The protective tube 6421 is a cylindrical member made of, for example, silicone resin or the like, and is for protecting the temperature sensor 642. Parts of the temperature sensor 642 located on both sides in the y direction sandwiching the part close to the back surface 622 are located between the pair of clamping parts 6413 and the pair of clamping parts 6414. In this embodiment, the protective tube 6421 covering these parts is sandwiched between the pair of clamping parts 6413 and the pair of clamping parts 6414. In addition, the protrusions 6417 of the pair of clamping parts 6413 and the pair of clamping parts 6414 strongly press the protective tube 6421. In a configuration without the protective tube 6421, the temperature sensor 642 may be sandwiched between the pair of clamping portions 6413 and the pair of clamping portions 6414, respectively.
[0092] A part of the temperature sensor 643 enters the opening 6412, and as shown in FIG. 19(b), this part is close to the back surface 622 of the heating unit 62. In this embodiment, the temperature sensor 643 is covered by a protective tube 6431. The protective tube 6431 is a cylindrical member made of, for example, silicone resin or the like, and is for protecting the temperature sensor 643. Parts of the temperature sensor 643 located on both sides in the y direction sandwiching the part close to the back surface 622 are located between the pair of clamping parts 6415 and the pair of clamping parts 6415. In this embodiment, the protective tube 6431 covering these parts is sandwiched between the pair of clamping parts 6415 and the pair of clamping parts 6416. In addition, the protrusions 6417 of the pair of clamping parts 6415 and the pair of clamping parts 6416 strongly press the protective tube 6431. In a configuration without the protective tube 6431, the temperature sensor 643 may be sandwiched between the pair of clamping portions 6415 and the pair of clamping portions 6416, respectively.
[0093] 18 and 19, the sensor support member 644 is for supporting the temperature sensor 642 and the temperature sensor 643. There is no limitation on the specific configuration of the sensor support member 644, and in this embodiment, the sensor support member 644 has a main portion 6441 and a protruding portion 6442. There is no limitation on the material of the sensor support member 644, and for example, a metal plate material is used.
[0094] The main portion 6441 is a portion along the xy plane. In the illustrated example, the main portion 6441 extends on both sides of the opening 6412 in a direction inclined with respect to the x and y directions when viewed in the z direction. The main portion 6441 is fixed to the heater support member 641 and the lower structure 3 by a screw 649.
[0095] The convex portion 6442 is provided at a position overlapping with the opening portion 6412 when viewed in the z direction, and protrudes from the main portion 6441 to the z1 side in the z direction.
[0096] 19(b), in this embodiment, the protruding portion 6442 enters the opening 6412 and abuts against the protective tube 6421 from the z2 side in the z direction. Also, the main portion 6441 abuts against the protective tube 6431 from the z2 side in the z direction. Note that the protruding portion 6442 may be configured to abut against both the protective tube 6421 and the protective tube 6431.
[0097] As shown in Fig. 20, in the humidifier A3, the display unit 92 is configured as a so-called transmissive display. That is, when the display unit 92 is not displayed, it has the same appearance as other parts of the side panel 14, and is not visually recognized as a part that displays information such as text. On the other hand, when a light-emitting unit disposed inside emits light, this light is transmitted, and the information such as text appears on the outside.
[0098] In the humidifier A3, the control unit 91 controls the heating unit 62 and the mist generating unit 63 according to the operating state of the air blowing unit 7. For example, the operation of the heating unit 62 and the mist generating unit 63 is stopped when the motor for driving the air blowing unit 7 is not rotating due to an unintended cause.
[0099] In the humidifier A3, as shown in Figs. 15 and 16, a first opening 1221, a second opening 1222, and a second opening 1223 are provided. The first opening 1221 is farther from the blower 7 than the center 620. Therefore, the air introduced from the first opening 1221 is sucked into the blower 7 after traversing the entire heating section 62. The temperature of the air introduced from the first opening 1221 increases as it traverses the heating section 62. On the other hand, the second opening 1222 and the second opening 1223 are provided at a position closer to the blower 7 than the center 620. Therefore, the degree of temperature increase of the air introduced from the second opening 1222 and the second opening 1223 is smaller than that of the air introduced from the first opening 1221. This makes it possible to more efficiently cool the areas around the heating section 62 that are located on the side of the heating section 62 (center 620) where the blower section 7 is located (the x1 side in the x direction), thereby making the temperature of each part more uniform.
[0100] In this embodiment, a plurality of screws 649 are arranged around the heating unit 62. If the temperature of the screws 649 rises excessively, problems may occur, such as a deterioration in strength of the resin screw receiving portion of the lower structure 3 that receives the screws 649 due to expansion and contraction, or cracks may occur. According to this embodiment, it is possible to prevent any of the plurality of screws 649 from becoming excessively hot.
[0101] 18 and 19, the temperature sensor 642 and the temperature sensor 643 are fixed by a pair of clamping parts 6413, a pair of clamping parts 6414, a pair of clamping parts 6415, and a pair of clamping parts 6416. This makes it possible to reduce the temperature sensor 642 and the temperature sensor 643 from rubbing against or contacting the heater support member 641, etc., even if an event such as the temperature sensor 642 and the temperature sensor 643 being pulled occurs during assembly or maintenance of the humidifier A3. This makes it possible to suppress damage to the temperature sensor 642 and the temperature sensor 643. It is preferable that the pair of clamping parts 6413, the pair of clamping parts 6414, the pair of clamping parts 6415, and the pair of clamping parts 6416 each have a protrusion 6417 in order to clamp the temperature sensor 642 and the temperature sensor 643 more reliably.
[0102] The humidifier according to the present invention is not limited to the above-described embodiment, and the specific configuration of each part of the humidifier according to the present invention can be freely designed in various ways. [Explanation of symbols]
