Description

[0001]
[Technical field to which the invention belongs]
  The present invention relates to a hybrid humidifier, and more particularly, to a hybrid humidifier having a vaporization type and a warm air type that are compact as a whole.
[0002]
[Prior art]
  Currently, there are hybrid humidifiers of a type consisting of a vaporizing filter and a fan, or a type of heater equipped with a heater. An example of the latter type of hybrid humidifier is shown in FIG. The hybrid humidifier 1 includes a cartridge-type water tank 3 containing water, a water storage tank 6 for storing a predetermined amount of water discharged from the water in the water tank 3, a filter 7 for sucking up water in the water storage tank 6, and water. It has a heater 9 for heating the air to be vaporized, a fan 8 for supplying atomized humidified air to the room, etc., and its functions are as follows.
[0003]
  That is, water is put into the cartridge type water tank 3 and placed in the main body case 2 upside down at a predetermined position. Then, the valve body 5 provided in the cap 4 screwed onto the upper portion of the water tank 3 is opened, and a predetermined amount of water in the water tank 3 is discharged. The discharged water flows out and is stored in a water tank 6 in which a float switch (not shown) is arranged, and when a part of the water in the water tank 6 is consumed, a predetermined amount of water in the water tank 3 is discharged again. The amount of water in 6 is always kept constant.
[0004]
  The water storage tank 6 extends to the space where the filter 7 is disposed. When the filter 7 is disposed upright in the space, the bottom of the filter 7 is immersed in water, and the filter 7 is disposed. Then, the filter 7 sucks up and holds the water at the bottom of the immersion. Further, a fan 8 is disposed in front of the filter 7, and the water sucked up and held by the filter 7 by driving the fan 8 is sucked out as an atomized state, and the atomized water Is supplied into the room through the air outlet 11.
[0005]
  By the way, the hybrid humidifier 1 shown in the figure includes a heater 9 in the vicinity of the filter 7, so that water sucked up and held by the filter 7 is heated and atomized by the fan 8. The water is atomized and vaporized, and is supplied to the room in a vapor state, thereby increasing the indoor humidity more effectively. Describing the outline again, the water in the water tank 3 flows out into the water tank 3 water storage tank 6 as indicated by a simple arrow, and is sucked and held by the filter 7 as indicated by a wavy arrow. When the fan 8 is driven, dry air in the room is sucked from a suction port 10 provided at the lower part of the main body case 2 as indicated by a white arrow, heated by the heater 9, and sucked up by the filter 7. Then, the retained water is atomized and vaporized to be supplied to the room as moist air from the outlet 11 as indicated by the black arrow.
[0006]
  The outline of the function of the hybrid humidifier is as described above. This hybrid humidifier is mainly used to increase the humidity because the indoor humidity decreases as a result of heating the room in the winter when the temperature decreases. And the usage form is also used indoors in the same way as a heater. In other words, placing the humidifier in the room means placing it with a heater, which means that the room becomes increasingly narrow.
[0007]
  However, as described above, the conventional hybrid humidifier is provided with the filter 7, the fan 8 and the heater 9, so the depth and height are inevitably increased, and it can sufficiently meet the demand for downsizing the whole. For that reason, it is a valuable product for those who think it is necessary, but for other people it is not a product that they would like to buy right away.
[0008]
[Problems to be solved by the invention]
  An object of the present invention is to provide a hybrid humidifier that is made compact by providing a passage from a water tank to a filter in a conventional hybrid humidifier and attaching a heating source such as a heater to the passage. It is what.
[0009]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention adopts the following configuration.
[0010]
  Invention of the present applicationComprises a water tank, a water storage tank for storing a predetermined amount of water in the water tank, a filter for sucking and vaporizing the water in the water storage tank, and a fan, in a passage from the water tank to the filter. Attach a heating source,The aboveFlowing through the passageSent to the filterThe water used for heating and humidifying air sucked by the fan,Heat with the heating sourceFlow through the filterThe structure which humidifies with warm air and warm water. And since the space which the conventional heater occupied by such a structure can be abbreviate | omitted, the whole humidifier is reduced in size so much. In addition, the conventional heater requires a mounting support for mounting and supporting the heater in the heater storage space, and a screw for mounting the heater on the mounting support, and the mounting is complicated. Since the heat source can be attached in advance on the outer periphery of the passage from the filter to the filter, the number of parts is reduced and the attachment is also simplified.MoreSince humidification can be efficiently performed with warm air and hot water, the entire humidifier is reduced in size without reducing the performance of the conventional humidifier.

  When the water tank 27 is housed and arranged in the main body case 21 in an inverted state, it is supported by the water storage wall 36, the long rib 49 and the short rib 50, and is housed and arranged in the space S1 in the form shown by the wavy line in FIG. At the same time, as shown in FIG. Thus, by extending the water tank 27 up to the length D in the space S2 in which the filter 28 is disposed, the capacity of the water tank 27 can be sufficiently increased by effectively using the internal space even if the humidifier is downsized. It can be secured greatly. 1, a tank recess 51 for avoiding the end filter portions 28a and 28a of the filter 28 is formed below the portion of the water tank 27 that extends into the space S2.
[0019]
  In the space S2, a filter 28 made of a known polymer porous member such as a polyethylene nonwoven fabric is accommodated. The water absorption filter 28 is an integral water absorption filter having an H-shaped cross section formed integrally with an end filter portion 28a, 28a at both ends and a central filter portion 28b connecting the two end filter portions 28a, 28a.

  The end filter portions 28a, 28a are portions of the same size and are disposed opposite to the inner sides of the air suction ports 52, 52 formed to face both side surfaces of the main body case 21, respectively. The air suction port 52 has a width that is slightly larger than the width d1 of the air suction port 52 and a height that is greater than the height h1 of the air suction port 52. The central filter portion 28b is a portion integrally connecting the two end filter portions 28a and 28a, and the thickness thereof is substantially the same as that of the two end filter portions 28a and 28a as shown in FIG. As shown in FIGS. 2 and 7, the height is substantially 1/4 of that of the two end filter portions 28a and 28a, and the bottom surface thereof is the same bottom surface as the two end filter portions 28a and 28a. .
[0021]
  Further, in the space S2, two support plates 53 for supporting the two end filter portions 28a, 28a of the filter 28 are provided so as to stand upright from the horizontal partition wall 23. The support plate 53 has substantially the same height as the end filter portion 28a. The end plate portion 28a is supported by the side wall of the main body case 21 and the support plate 53, and the filter 28 is stored in the space S2 from above. After that, the two end filter portions 28a and 28a are arranged to face the inner sides of the air inlets 52 and 52 provided on both side walls of the main body case 21, respectively. become. By arranging the two end filter portions 28a and 28a in such a form, the two end filter portions 28a and 28a can be combined with a function for vaporizing water and a function for filtering air. By setting the height of the central filter portion 28b as described above, the volume of the extending portion of the water tank 27 to the space S2 can be sufficiently increased. The center filter portion 28b is not necessarily described, but if not, the volume of the extending portion of the water tank 27 to the space S2 can be further increased.
[0022]
  Further, a filter water tank 54 is formed by the first vertical partition wall 24 and the long rib 49 below the space S2. An inflow pipe 59 having an inflow port 58 is suspended from the bottom of the filter water tank 54 in a space S5 as a lower space. After the water tank 27 is accommodated in the main body case 21, the water tank 27 Water is introduced through the communication pipe 60 described later, and the water w flows in until the liquid level of the water storage tank 35 is reached. The state is shown in FIG. When the water w is introduced into the filter water tank 54, the bottom of the filter 28 is submerged below the surface of the water, so that the water w is sucked up above the filter 28 and wets the entire filter 28 and is vaporized. become.
[0023]
  A fan 29 is disposed in the space S3. The fan 29 is a long and narrow sirocco fan, and the peripheral portion thereof is of a size located in the vicinity of the air inlets 52 and 52 provided on both side surfaces of the main body case 21. By using the fan 29 having such a size, it is possible to promote the vaporization of water in the end filter portions 28a and 28a and improve the humidification efficiency. In addition, the first vertical partition wall 24 that partitions the space S3 is provided with a circular opening 55 at a position facing the front surface of the fan 29, and the lid 22 on the upper surface of the space S3 is also illustrated in FIG. As shown in the figure, an air outlet 56 formed of a plurality of slits is provided, and when the fan 29 is driven, air that has been humidified through the filter 28 is sucked from the opening 55 and is provided in the upper lid body 22. It discharges to the room from 56.
[0024]
  A motor 30 is disposed in the space S4. The motor 30 is connected to the fan 29 via a shaft 57 and rotates the fan 29. The space S4 is completely delimited by the second vertical partition wall 25 so that humid air in the space S3 does not enter the space S4.
[0025]
  The space S5 is a lower space formed between the horizontal partition wall 23 and the bottom plate 26, and an outflow pipe 48 hanging down from the rectangular chamber 39 of the water storage tank 35 and an inflow pipe 59 hanging down from the filter water tank 54 are provided. It protrudes. In this space S5, a communication pipe 60 is disposed as a water passage from the water tank 27 to the filter 28. The communication pipe 60 is a U-shaped cross section composed of a first elbow pipe 60a, a second elbow pipe 60b, and a central straight pipe 60c. The other end of the first elbow pipe 60a is connected to the rectangular chamber 39 of the water storage tank 35. The second elbow pipe 60b is connected to the hanging outflow pipe 48, and the other end of the second elbow pipe 60b is connected to the inflow pipe 59 hanging from the filter water tank 54.
[0026]
  The outflow pipe 48 that hangs down from the rectangular chamber 39 of the water storage tank 35 and the inflow pipe 59 that hangs down from the filter water tank 54 are provided on a substantially diagonal line of the main body case 21 in plan view as shown in FIG. As shown in FIG. 4, the communication pipe 60 is attached on the substantially diagonal line of the main body case 21 in a plan view. Even if the humidifier 20 is downsized, the communication pipe 60 can be lengthened. The capacity of the heater 61 provided in the communication pipe 60 can be increased. Further, as shown in FIG. 2, the central straight pipe 60c is disposed substantially horizontally. Since the float switch 40 is suspended from the horizontal partition wall 23 to substantially the center of the space S5 as shown in FIG. 3, the float switch 40 is provided at a position avoiding the communication pipe 60. Moreover, although the center straight pipe 60c is shown horizontally, it may be inclined or curved in a plan view.
[0027]
  A heater 61 as a heating source is wound around the outer periphery of the central straight pipe 60 c of the communication pipe 60 to warm water flowing in the communication pipe 60. The heater 61 is a mica heater, and the heating temperature is controlled in the vicinity of the heater 61 by a temperature controller at 50 ° C. to 80 ° C. Then, the temperature of the water is controlled so that impurities such as minerals in the water do not precipitate in the passage through which the water passes, for example, about 60 ° C. or lower. As a result, warm hot water is supplied to the filter water tank 54, and this warm hot water is sucked up by the filter 28. The heating source is not limited to the heater, and for example, an electromagnetic induction heating method in which the central straight pipe 60c is formed of a magnetic material and a coil is disposed on the outer periphery thereof may be used.
[0028]
  As described above, since the central straight pipe 60c of the communication pipe 60 to which the heater 61 is attached is provided on a substantially diagonal line of the main body case 21, it can be made sufficiently long even if the humidifier 20 is downsized, As a result, the heating efficiency can be increased and the humidification efficiency can be increased. The temperature of the water is set to a temperature at which impurities such as minerals do not precipitate, and the supplied water is supplied as warm hot water of about 60 ° C. Therefore, the temperature of the humidified air discharged from the outlet 56 is the temperature of the hot water. Even if the humidified air discharged from the air outlet 56 is directly on the skin, there will be no burns.
[0029]
  Moreover, since warm hot water is sucked into the filter 28, the suction effect of the fan 29 improves the vaporization efficiency of the filter 28. Even if the humidifier 20 is downsized, sufficient humidification effect is achieved. Can be achieved.
[0030]
  As shown in FIG. 5, the air outlet 56 is provided on the upper surface of the cover plate 22, and the operation unit of the humidifier 20 is also provided on the upper surface of the cover plate 22 and in the vicinity of the air outlet 56. The operation unit includes an operation switch 62 that turns on and off the motor 30, a heater switch 63 that turns on and off the heater 61, an operation LED 64 that lights when the operation switch 62 is turned on, a heater LED 65 that lights when the heater 61 is turned on, and The water supply LED 66 is turned on when the water W in the water tank 27 runs out.
[0031]
  In addition, the conventional humidifier provided the operation part as much as possible from the blower outlet. The reason is that the steam humidifier using a heater has a problem that hot humidified air is discharged from the outlet and the operation unit cannot be disposed in the vicinity thereof. However, the humidifier is often placed near the wall of the room, and when a humidifier arranged with the operation unit and the air outlet is placed apart from the wall, it is common knowledge that the air outlet is located at the wall. Although it will be placed inside, it will cause another problem that the operation of the operation unit becomes difficult. In the humidifier of the present application, as described above, hot humidified air is not discharged from the outlet 56, so even if an operation unit is provided in the vicinity of the outlet 56, there is no problem of heat as described above. In addition, such an arrangement does not hinder the operation.
[0032]
  Next, the humidification operation during the humidification operation will be described in order. In the humidification operation, the integrated water absorption filter 28 is installed in the space S2, and then the water tank 27 containing the water W is inverted in the space S1. And S2 are stored and arranged. Then, the water in the water tank 27 flows out into the water storage tank 35, and the water that flows out flows through the first circular chamber 37, the second circular chamber 38, and the rectangular chamber 39 from the outlet 47 of the outflow pipe 48 to the communication pipe 60 in the space S 5. Will be leaked. When a predetermined amount of water is stored in the entire water storage tank 35, the float switch 40 installed in the second circular chamber 38 is turned on, and the motor 30 can be driven.
[0033]
  The water flowing out from the outlet 47 into the communication pipe 60 in the space S5 is heated by the heater 61 wound on the outer periphery of the communication pipe 60 that is energized when the heater switch 63 of the operation unit is turned on, and becomes hot water. Then, the water w flows into the filter water tank 54 via the inflow pipe 59 and the water w is accumulated until the water level becomes the same as that of the water storage tank 35. The hot water that has flowed into the filter water tank 54 is sucked up by the filter 28 to make it entirely wet, and the hot water sucked up by the filter 28 is vaporized.
[0034]
  When the operation switch 62 of the operation unit is turned on in such a state, the fan 29 is rotated by the motor 30. Then, the indoor dry air is introduced into the space S2 from the air inlet 52 in the direction of the white arrow shown in FIG. Dust and the like are removed from the introduced air by the filter 28, and the hot water that has been moistened is made into an atomized state, the vaporizing action by the filter 28 is further increased, the air is rapidly humidified, and the humidified air is supplied to the fan. It will be sent out in 29 directions. Then, the sent humid air is discharged into the room from the blowout port 56 along the direction indicated by the white arrow in FIGS. 2 and 3 by the fan 29.
[0035]
  In the present invention, since the heater 61 as a heating source is attached to the passage from the water tank 27 to the filter 28, the storage space occupied by the heater 61 is not required, so that the entire humidifier can be made compact accordingly. In addition, since the heating temperature is set to a temperature at which impurities such as minerals in water do not precipitate, the vaporizing action of hot water wetted by the filter 28 is slightly lower than that heated at a higher temperature, but there is no precipitation of impurities. Therefore, since the temperature of the humidified air discharged into the room through the outlet 56 is low, even if the humidified air directly hits the skin, it can be used with peace of mind. .

The motor 138 is connected to the fan 135 via a shaft 139 and rotates the fan 135. The space S4 is completely delimited by the second vertical partition wall 106 so that humid air in the space S3 does not enter the space S4. In this space S4, a microcomputer board 143 is provided as shown in FIG.
[0047]
  The space S5 is a lower space formed between the horizontal partition wall 104 and the bottom plate 103, and an outflow pipe 116 that hangs down from the water storage tank 113 and an inflow pipe 129 that hangs down from the filter water tank 127 protrude. As shown in FIG. 8, the inflow pipe 129 is located at a substantially central portion of the humidifier 100, and the outflow pipe 116 is also located on the front right side as shown in FIG. A first elbow pipe 130 is connected to the tip of the outflow pipe 116, a second elbow pipe 131 is connected to the tip of the inflow pipe 129, and the first elbow pipe 130 and the second elbow pipe 131 are connected to each other.

[0048]
  Note that a mica type heater is used as the heater 133, and a temperature controller is provided near the heater 133 and temperature control is performed at 50 ° C. to 80 ° C. Then, the temperature of the water is controlled so that impurities such as minerals in the water do not precipitate in the passage through which the water passes, for example, about 60 ° C. or lower. As a result, warm hot water is supplied to the filter water tank 127, and this warm hot water is sucked up by the filter 125. The heating source is not limited to the heater, and for example, an electromagnetic induction heating method in which the central straight tube 132 is formed of a magnetic material and a coil is disposed on the outer periphery thereof may be used.
[0049]
  Next, the air flow will be described. Regarding the air flow, an arrow number is attached to the perspective view of FIG. 12 to show an outline of the entire flow, and a part of the flow is also shown by arrows in FIGS. 8 and 10. An air suction port 140 is provided on the front side of the space S5, and when the fan 135 is rotated, an arrow is drawn from the air suction port 140.1 roundAs shown in the diagram, air is introduced into the space S5. The introduced air is indicated by an arrow along the heater 133 attached to the outer periphery of the communication pipe 134.Round 2As shown by, it flows from the front toward the rear in the space S5. By the way, as shown in FIG.8 and FIG.10, the long communication path 141 which penetrates the horizontal partition wall 104 up and down is provided in the left side part of the humidifier 100. As shown in FIG. The communication passage 141 is a cylindrical passage having a rectangular cross section, and a window 142 communicating with the upper space S12 is provided on the upper side surface thereof as shown in FIG. The spaces S5 and S12 are communicated with each other.
[0050]
  Therefore, the air introduced into the space S5 from the air inlet 140 and heated by the heater 133 is indicated by an arrow.Round 3As shown by the arrow, it passes through the communication path 141 from the lower part of the communication path 141,Round 4As shown in FIG. 6, it is introduced into the upper space S12 through the upper window 142. The warm air introduced into the upper space S12 also circulates into the lower space S13. From both the spaces S12 and S13, an arrow appears from the front of the filter 125.Round 5As shown, the hot water flowing into the filter 125 and adsorbed by the filter 125 is efficiently atomized, and the atomized humidified air is sucked out by the fan 135 from the opening 136 provided in the first vertical partition wall 105. And then arrowRound 6As shown by, the air is discharged into the room from the air outlet 137 provided in the upper part of the space S3.
[0051]
  The humidification during the humidification operation will be described in order. In the humidification operation, the filter 125 is installed in the space S2, and then the water tank 108 containing the water W is stored and arranged in the space S11 in an inverted state. Then, the water in the water tank 108 flows out into the water storage tank 113, and the water that flows out flows out from the outlet 117 of the outflow pipe 116 to the communication pipe 134 in the space S5. When a predetermined amount of water is stored in the entire water storage tank 113, the float switch 115 is turned on and the motor 138 can be driven. The water flowing out from the outlet 117 to the communication pipe 134 in the space S5 is heated by the heater 133 energized by turning on the heater switch of the operation section (not shown) to become hot water, and then into the filter water tank 127 through the inlet pipe 129. The hot water is accumulated until it flows in and reaches the same water level as the water tank 113. The hot water that has flowed into the filter water tank 127 is sucked up by the filter 125 to make the whole wet, and the hot water sucked up by the filter 125 is vaporized.
[0052]
  Here, the operation of the ball valve 123 will be described. As described above, the ball valve 123 moves upward by buoyancy when water is stored in the entire valve storage box 118, contacts the upper valve seat 121 of the valve storage box 118, and closes the upper opening 119 thereof. Therefore, the water sent from the communication pipe 134 to the filter water tank 127 is not sent to the filter water tank 127 but is stopped when it reaches the vicinity of the outlet of the inflow pipe 129. When the heater 133 is energized in this state, only water in the communication pipe 134 is heated, so the water in the communication pipe 134 is heated to a predetermined temperature in a short time. When the water in the communication pipe 134 is heated to a predetermined temperature, part of the hot water in the communication pipe 134 is pushed out into the filter water tank 127. When a part of the hot water is pushed out into the filter water tank 127, a vacuum is generated in the communication pipe 134. Therefore, the ball valve 123 is pushed down and the water in the water storage tank 113 is introduced into the communication pipe 134. As a result, the hot water is introduced into the filter water tank 127 up to the same water level as the water tank 113. In this case, the amount of heat generated by the heater 133 and the rotational speed of the fan 135 are set to be proportional.
[0053]
  During humidification, the hot water introduced into the filter water tank 127 is sucked up by the filter 125, atomized more efficiently by hot air, and discharged into the room as humidified air from the outlet 137. As a result, the hot water in the communication pipe 134 is replenished into the filter water tank 127 one after another by repeating the above-described state. As described above, only a small amount of water can be heated by the heater 133 such as the water in the communication pipe 134. Therefore, compared to the conventional boiler type, the water can be heated quickly and with less electric power, which greatly contributes to energy saving. be able to.
[0054]
  Also in this embodiment, since the heater 133 as a heating source is attached to the passage from the water tank 108 to the filter 125, the storage space occupied by the heater 133 is not required, so that the entire humidifier is made compact accordingly. Can do. In addition, since the heating temperature is set to a temperature at which impurities such as minerals in the water do not precipitate, the vaporizing action of hot water wetted by the filter 125 is slightly lower than that heated at a higher temperature, but there is no precipitation of impurities. Therefore, since the temperature of the humidified air discharged from the air outlet 137 into the room is low, even if the humidified air directly hits the skin, it can be used with peace of mind. .
[0055]
  By the way, in the above-mentioned vaporization type humidification using a filter, the occurrence of mold and bacteria on the filter is always a problem. Some humidifiers use anti-fungal and antibacterial filters, and filter drying and hot water sterilization with a microcomputer method. The humidifier of the present invention adopts a single-function non-microcomputer method. A control method suitable for the method will be described below. The description will be made with reference to the first embodiment.
[0056]
  In this control, even if the water in the water tank 27 runs out and the water supply LED is turned on, the heater 61 is turned off, but the fan 29 continues to rotate until the operation switch 62 is turned off to dry the filter 28. .
[0057]
  Referring to the flowchart of FIG. 13, first, it is determined in step S1 whether or not the operation switch 62 of the operation unit is turned on. If not yet turned on, the process proceeds to step S2, and the fan 29 and the heater 61 are stopped in step S2. Further, the operation LED 64, the heater LED 65, and the water supply LED, which are various indicator lights, are kept off.
[0058]
  If it is determined in step S1 that the operation switch 62 has been turned on, the process proceeds to step S3, where the fan 29 is rotated and the operation LED 64 is lit. In step S4, it is determined whether or not the float switch 40 is turned on in step S4, that is, whether or not a predetermined amount of water has been stored in the water tank 35. A predetermined amount of water is stored in the water tank 35 and floated. If it is determined that the switch 40 is turned on, the process proceeds to step S6, and humidification by the hybrid is performed.
[0059]
  For this humidification, two modes of whether or not to use the heater 61 are prepared. When the heater switch 63 is not turned on in step S6, the process proceeds to step S7, where the humidification mode without the heater 61, That is, the humidification mode is executed by the vaporizing action of the fan 29 and the filter 28 with the heater 61 off and the heater LED 65 and the water supply LED turned off. When the heater switch 63 is turned on in step S6, the process proceeds to step S8, where the humidification mode with the heater 61 is used, that is, the heater 61 is on, the heater LED 65 is lit, and the water supply LED is turned off. The hybrid humidification mode by the vaporizing action of the hot water, the fan 29 and the filter 28 is executed.
[0060]
  If it is determined in step S4 that the float switch 40 is not turned on, the process proceeds to step S5. In step S5, the heater 61 is off, the water supply LED is lit, and the fan 29 is in a rotating state. This state is a state after the water in the water tank 27 runs out during humidification, or a state selected for the purpose of drying the filter 28 from the beginning. In the former case, water is put into the water tank 27. If it replenishes, it will progress to step S6 automatically and humidification of step S7 or step S8 will be performed. If the operator decides to dry the filter 28 even if it is the former, the fan 29 continues to rotate while the heater 61 is turned off, and the filter 28 is dried to prevent the generation of mold and fungi. can do.
[0061]
  In the latter case, that is, the state selected for the purpose of drying the filter 28 from the beginning, if the operation is continued as it is, the fan 29 continues to rotate with the heater 61 turned off, so that the filter 28 is dried, The generation of bacteria can be prevented. If the operation switch 62 is turned off after the filter 28 is dried, the drying mode of the filter 28 is stopped.
[0062]
  In the second embodiment, the ball valve 123 is used. However, in the drying of the filter 125 in this embodiment, even when the water in the water storage tank 113 is contained, the ball valve 123 is used. The filter 125 can be easily dried.
[0063]
  That is, the heater 125 is turned off and the filter 125 is dried. However, when the heater 133 is turned off and the filter 125 is dried by driving the fan 135, the water in the filter water tank 127 and the communication pipe 134 is removed. The air is exhausted from the outlet 137 as humidified air, and there is no water in the filter water tank 127 and the communication pipe 134. However, since the ball valve 123 remains in contact with the lower valve seat 122 in the valve storage box 118, for example, in the water tank 113. Even if water is contained, the water does not flow into the communication pipe 134 and the filter 125 can be dried without any trouble.
[0064]
  The present invention is not limited to the configuration of the above-described embodiment, and can be appropriately changed in design without departing from the gist of the invention.
[0065]
【The invention's effect】
  In the present invention, a heating source is attached to the passage from the water tank to the filter, and the heating source heats the water flowing through the passage and being sent to the filter, and the humidifying air sucked by the fan is heated by the heating source. Flow through the filterThus, since the space occupied by the conventional heater can be omitted, the entire humidifier can be downsized accordingly. In addition, the conventional heater requires a mounting support for mounting and supporting the heater in the heater storage space, and a screw for mounting the heater on the mounting support, and the mounting thereof is complicated. Since the heat source can be attached in advance to the outer periphery of the passage extending from the filter to the filter, the number of parts can be reduced, and the attachment can be easily performed, and the production cost can be reduced. Furthermore, since the humidifier can be downsized, the humidifier does not occupy a large area in the room, so that the utility value is increased. Further, by heating the humidifying air sucked by the fan with a heating source, the atomization at the filter is increased by the hot air and the hot water, and the humidification efficiency can be further improved. Therefore, even if the whole humidifier is reduced in size, the capability of the humidifier can be sufficiently improved.
