Description

  The present invention relates to a humidifying device including a vaporizing filter and a fan.

  2. Description of the Related Art Conventionally, a vaporizing humidifier is configured to vaporize humidifying water by vaporizing means so as to send out humidifying air to the outside of the main body (see, for example, Patent Document 1).

  Further, there are a hybrid type that uses a heater and humidifying air in combination, a heater type that generates steam by heating, and an ultrasonic type that uses ultrasonic vibration.

JP 2010-249511 A

  However, the vaporizing type has low power consumption, but has a large air volume, so that the product is large and the driving noise tends to be large.

  The hybrid type uses a heater and humidifying air in combination, so that the product can be reduced in size, but the power consumption is large.

  Furthermore, since the heater type is a method of boiling hot water, the boiler can be downsized, but care must be taken in handling hot water.

  In addition, the above ultrasonic type has low power consumption and gives a feeling of humidification, but because it is a structure that directly jets water, the surroundings are wetted with water, scale components and breeding germs present in the water tank are removed. It becomes easy to scatter.

  The present invention has been made in order to solve the above-described problems, and can reduce power consumption and operation noise. In addition, the increase in the area of the vaporization filter can be suppressed, and the rotational speed of the fan can be reduced. It is in providing the humidification apparatus which can suppress.

  In the first aspect of the invention, by reversing the rotation direction of the vaporization filter and the fan, the wind speed applied to the vaporization filter is substantially increased and the amount of vaporization is increased, so that the rotation speed of the rotation driving means can be reduced.

In the first aspect of the invention, the wind from the fan heading downward is bounced back by the tray to increase the wind speed and is discharged from the lower side near the tray. On the other hand, the wind speed of the humidifying air exhausted from the upper part opposite to the tray is, for example, half the slow speed compared to the lower side, but by moving the fan upward, the exhaust speed from above is increased, and from near the tray. The discharge speed can be lowered and the balance can be achieved as a whole. Furthermore, the tray is provided with a water storage section, and supplies water in the storage section from the inside of the vaporization filter to the vaporization filter.

According to the second aspect of the present invention, the air blown outward as a characteristic of the side suction and outer peripheral blowout fan is dispersed into a portion blown in a right angle direction and a portion flowing downstream. When the fan is positioned downstream from the center of the vaporization filter, the wind speed received by the vaporization filter is not uniform in the axial direction, and the downstream side becomes faster and the air volume is concentrated. As a result, the axial dimension is increased more than necessary to obtain the desired amount of humidification, but by providing the fan upstream with respect to the axial direction of the vaporization filter, the air blown outward from the fan Is dispersed in a portion that is blown out in a right angle direction and a portion that flows to the downstream side, and almost uniformly passes through a wide range of the vaporizing filter, and the humidifying liquid contained in the vaporizing filter can be efficiently vaporized.

  According to the invention of claim 1, by reversing the rotation direction of the vaporization filter and the fan, the wind speed hitting the vaporization filter is substantially increased, so that power consumption can be achieved and operation noise can be reduced. Can do.

According to the invention of claim 1 , the wind speed of the wind reflected from the tray and discharged from the lower side is increased, whereas by providing the rotation center position of the fan above the rotation center position of the vaporization filter, The wind speed of the wind discharged from the upper side is increased, and thereby the vaporization filter is uniformly vaporized, so that power consumption can be reduced and operation sound can be reduced. Moreover, since it comprised so that water might be supplied to this vaporization filter from the inner side of a vaporization filter, the lower part of a vaporization filter does not contact the water of a tray. And a tray is provided with the storage part of water, and can supply the water of this storage part to this vaporization filter from the inner side of a vaporization filter.

According to the invention of claim 2 , by uniformly applying the wind of the fan in the axial direction of the vaporization filter, it is possible to efficiently vaporize, suppress the enlargement of the area of the vaporization filter, and reduce the rotation speed of the fan. Can be suppressed.

It is the perspective view seen from the back direction of the humidification device same as the above. It is an exploded perspective view of a humidification device same as the above. It is a longitudinal cross-sectional view of a humidification apparatus same as the above. FIG. 5 is a cross-sectional explanatory view showing the positional relationship in the axial direction of a vaporizing filter and a fan according to a second embodiment of the present invention, and FIG. 5A, which is the second embodiment, is a comparative example in which the fan is on the upstream side.

  Hereinafter, several preferred embodiments of the humidifier according to the present invention will be described with reference to the accompanying drawings. In the following embodiments, common components are denoted by common reference numerals, and descriptions of common portions are omitted as much as possible to avoid duplication.

1 to 4 show a humidifying device according to a first embodiment of the present invention. First, the overall configuration of the humidifier will be described with reference to FIGS. 1 to 3. 1 is a substantially cylindrical bottomed body having an opening on the back side, 2 is a rear cover for closing the back opening of the body 1 , 3 is a rear panel attached to the back surface of the main body 1 so as to cover the rear cover 2, and 4 is a front panel attached to the front surface of the main body 1. In this embodiment, an outer member that forms the appearance of the humidifier is formed by the resin main body 1, the rear panel 3, and the front panel 4.

  The main body 1 is provided with a fan 6 in which a plurality of blades 5 are arranged radially, and a blower motor 7 serving as a rotation driving means of the fan 6. A rotation shaft 8 of the blower motor 7 is provided at the center of the fan 6. The fan 6 is attached and fixed to the rotating shaft 8 by passing through the formed hole 9 and screwing the spinner 10 to the tip of the rotating shaft 8 protruding from the rear side of the fan 6. In addition, the main body 1 is a donut-shaped and annular vaporizing filter 11 that surrounds the outer periphery of the fan 6, a tray 12 disposed below the vaporizing filter 11, and water supply for feeding water that is liquid to the vaporizing filter 11. And a gear motor 13.

  The fan 6 is configured as a turbo fan or a sirocco fan that sucks air from the side and discharges air from the outer periphery. Further, the rotation shaft 8 of the blower motor 7 is arranged so that the axial direction thereof coincides with the front-rear direction of the main body 1.

  An upper panel 1J of the main body 1 is provided with an operation panel 18 having an operation section 16 composed of a plurality of buttons and a display section 17 such as an LED, and a substantially L-shaped handle 19 that can be raised and lowered with respect to the main body 1. Is provided. Further, exhaust ports 20 having a large number of openings are respectively provided on the left and right side portions of the main body 1. The exhaust port 20 is formed so as to surround the outer periphery of the fan 6 perpendicular to the exhaust direction of the fan 6.

  The rear panel 3 is provided with an air inlet 21 having a number of openings. The air inlet 21 is formed orthogonal to the axial direction of the rotary shaft 8 which is the air intake direction of the fan 6. Further, an air circulation port 22 is formed in the rear cover 2 as an intermediate member between the rear panel 3 and the fan 6 so as not to block the air flow from the intake port 21 toward the fan 6. .

  A tank 23 as a liquid supply source is detachably disposed between the main body 1 and the front panel 4. As is well known, the tank 23 includes a container 24 that stores water and a cap 25 that is detachably attached to the mouth of the container 24. The cap 25 is provided with a valve body (not shown). When the tank 23 is mounted upright on the main body 1 with the cap 25 down, the valve body is pushed from the tray 12 side, and the water in the tank 23 is drained. It is sent out to the storage part 27 of the tray 12 formed in a bottomed shape. The liquid level in the storage unit 27 at this time is defined at the lower end position of the tank 23 regardless of the remaining amount of water stored in the tank 23. It should be noted that the front panel 4 is also detachably disposed with respect to the main body 1 by, for example, claw fitting or the like because the tank 23 is frequently detached from the main body 1.

  The vaporization filter 11 is attached to a filter case 31 as a filter support formed in a drum shape so that a band-shaped filter material 32 as a filter body is wound around the filter case 31. The filter case 31 is formed by connecting a plurality of support columns 35 between a pair of front and rear frame bodies 33, 34 formed in a ring shape, and the filter material 32 is disposed outside each support column 35.

  In addition to the storage unit 27 described above, the tray 12 includes water supply means 37 that guides and supplies the water stored in the storage unit 27 to the vaporization filter 11 using the gear motor 13 as a drive source. The water supply means 37, in addition to the rotatable gear 38 connected to the rotation shaft of the gear motor 13 and the rotatable handle rod 39 for pumping up the water stored in the storage portion 27, water pumped up by the handle rod 39, A shower unit 40 that supplies water by guiding it to the inside of the vaporization filter 11 is provided. When the rotational force of the gear motor 13 is applied to the gear 38, the vaporizing filter 11 having a tooth portion meshing with the gear 38 rotates around the fan 6, and the rotational force of the vaporizing filter 11 is transmitted to the handle 39. Thus, the handle 39 having a so-called water-pumping water wheel structure is configured to pump up the water in the storage unit 27 and supply water from the inside of the vaporization filter 11 toward the filter material 32.

  In this embodiment, the fan 6 and the vaporization filter 11 are arranged around the blower motor 7. Here, when the operation of the humidifier is started by operating a button (for example, an operation off / on button) of the operation unit 16, predetermined power is supplied to the blower motor 7, and the fan 6 rotates inside the main body 1. Rotate around axis 8 Thereby, the humidification air taken in from the rear side surface of the fan 6 through the inlet port 21 through the circulation port 22 changes its direction in the outer peripheral direction of the fan 6 and passes through the vaporization filter 11. In addition, during operation of the humidifier, predetermined power is supplied to the gear motor 13 as necessary, so that the water is directed from the inside of the vaporization filter 11 toward the filter material 32 while rotating the vaporization filter 11 inside the main body 1. Is supplied, and the filter material 32 always contains water. Therefore, the humidifying air that passes through the vaporizing filter 11 as the fan 6 rotates takes moisture from the filter material 32 and is discharged as wet air to the exhaust port 20 formed on the side surface of the main body 1.

  41 is an atomizer incorporated in the main body 1. The atomization device 41 operates by operating another button (for example, a pico ion button) of the operation unit 16 during operation of the humidifier, and a mist discharge port 42 formed between the operation panel 18 and the exhaust port 20. Thus, a fine mist having a fine particle diameter charged with negative ions is released.

  Incidentally, in the vaporizing humidifier, if the usage environment such as the environmental temperature and humidity is constant, the vaporization amount depends on the wind speed of the humidifying air passing through the vaporizing filter 11. For this reason, adjusting the wind speed to match the vaporization characteristics unique to the material of the vaporization filter 11 is one of the factors that enhance vaporization efficiency. Moreover, if the wind speed is increased, the absolute value of the amount of vaporization increases, but the efficiency decreases, leading to an increase in power consumption and driving sound. On the other hand, if the wind speed is lowered, the humidification amount itself is reduced. In order to increase the vaporization efficiency, it is important to give a uniform wind speed to the entire vaporization filter 11.

  Therefore, the present invention employs the following characteristic configuration.

  The tray 12 is disposed on the lower side in the main body 1 and is disposed on the side close to the floor as the mounting surface of the main body 1 in use. The vaporization filter 11, the fan 6 and the blower motor 7 are disposed above the tray 12 in the main body 1.

  As shown in FIG. 4, the fan 6 is arranged in a non-contact state in the vaporization filter 11, the rotation center axis 11 </ b> A of the vaporization filter 11 and the rotation center axis 6 </ b> A of the fan 6 are arranged in the front-rear direction, and Further, the rotation center shaft 6A of the fan 6 is disposed above the rotation center shaft 11A of the vaporization filter 11. Moreover, it is preferable to arrange | position so that rotation center axis 6A, 11A may be located in the same perpendicular | vertical surface. The fan 6 is provided at a concentric position with respect to the central axis of the blower motor 7 which is the rotation shaft 8 of the blower motor 7 so as to surround the blower motor 7 having a substantially circular shape when viewed from the front.

  The left and right side lower portions 1L and 1R below the exhaust port 20 of the main body 1 and the upper surface portion 1J are closed, and the front panel 4 is closed at the lower portion of the intake port 21. 12 is arranged in a substantially closed internal space.

  The tray 12 has a bottomed box shape with an open top, a bottom surface portion 12T that is long in the left-right direction, front and rear side surface portions 12F and 12B that are erected from four sides of the bottom surface portion 12T, and left and right side surface portions 12L and 12R. Are housed in the lower space 51 of the main body 1, and the side surface portions 12F, 12B, 12L, 12R have substantially the same height as the left and right side lower surface portions 1L, 1R of the main body 1.

  A fan 6 and a vaporizing filter 11 are arranged around the air blowing motor 7, and the humidifying air sucked by the rotating fan 6 through the air inlet 21 and the circulation port 22 is indicated by an arrow in FIG. 4. As shown in FIG. 3, the air passes through the vaporization filter 11 and is discharged from the exhaust port 20 to the outside of the main body 1 as wet air.

  The vaporization filter 11 is attached so that the filter material 32 is wound around the filter case 31, and the rotation force of the gear motor 13 is transmitted to the vaporization filter 11 by the gear 38 to rotate the vaporization filter 11. The handle 39 draws up the water in the storage unit 27 by the rotation, and water is supplied to the filter material 32 from the inside of the vaporization filter 11. In this case, the pumped water is dropped inside the filter material 32 from a hole (not shown) provided in the tray 40A of the shower unit 40.

  Further, the fan 6 is configured to be driven to rotate in the opposite direction with respect to the rotation direction of the vaporization filter 11. In other words, the vaporization filter 11 is rotationally driven in the reverse direction with respect to the fan 6 that is rotationally driven in the direction of sucking air from the side surface and discharging air from the outer periphery. In this case, the main body 1 includes control means (not shown) that controls the vaporization filter 11 to rotate in the direction opposite to the rotation direction of the fan 6. Further, the vaporization filter 11 rotates at a lower speed than the fan 6.

  As described above, in this embodiment, the tray 12, the cylindrical vaporization filter 11 that is rotatably disposed above the tray 12, the fan 6 that is disposed in the vaporization filter 11, and the fan 6 are driven to rotate. The rotation motor is driven by a blower motor 7 and an exhaust port 20 provided outside the vaporization filter 11. The vaporization filter 11 is rotationally driven in the direction opposite to the rotation direction of the fan 6. The number of rotations of the blower motor 7 can be reduced substantially, power consumption can be reduced, operation noise can be reduced, and a highly efficient humidifier with a reduced number of rotations of the fan 6 can be obtained.

  Further, in the conventional product, the wind from the fan 6 directed toward the floor is bounced back by the tray 12 to increase the wind speed and is discharged from the lower side of the exhaust port 20, while the wind speed of the humidifying air discharged from the upper part is the floor speed. The wind speed is more than half that of the part close to.

  Therefore, in the present embodiment, the rotation center position of the fan 6 is provided above the rotation center position of the vaporization filter 11, so that the discharge speed from the upper side of the exhaust port 20 is increased and the discharge is performed from the lower side of the exhaust port 20. Balance can be achieved by lowering the wind speed.

  Further, by providing the rotation center position of the fan 6 above the rotation center position of the vaporization filter 11, the tray 40 </ b> A of the shower unit 40 is disposed between the lower outer periphery of the fan 6 and the lower inner periphery of the vaporization filter 11. Space can be secured and workability of assembling the shower unit 40 to the main body 1 can be improved.

  Further, since the vaporizing filter 11 is provided with a tooth portion on the frame 33 of the filter case 31 and a tooth portion that meshes with the tooth portion and transmits rotation, the handle rod 39 is provided with the vaporizing filter 11 by the gear motor 13. Both of the handle rods 39 can be rotationally driven.

In addition, since the water in the storage unit 27 is supplied from the inside of the vaporization filter 11 toward the filter material 32 of the vaporization filter 11, the lower part of the vaporization filter 11 is not in contact with the water in the storage unit 27. During the stoppage, excess water is not supplied to the vaporization filter 11.

  FIG. 5 shows a main part of the humidifying device according to the second embodiment of the present invention. As shown in FIG. 5, the vaporization filter 11 is formed longer than the fan 6 in the rotation axis direction, and the filter material 32 is also formed longer than the fan 6. In FIG. 5A corresponding to the embodiment, the fan 6 is replaced with the vaporization filter. In FIG. 5B, which is a comparative example, the fan 6 is disposed substantially at the center in the axial direction of the vaporization filter 11, and in FIG. 5C, which is a comparative example, 6 is arranged on the downstream side in the axial direction of the vaporization filter 11. In any of the embodiments, the fan 6 is disposed in the vaporization filter 11.

  As described above, as a characteristic of the side suction / outer periphery discharge fan 6, the air blown to the outer periphery is dispersed into a portion discharged in a right angle direction and a portion flowing downstream.

  For this reason, when the fan 6 is disposed at the position shown in FIGS. 5B and 5C, the wind speed received by the vaporizing filter 11 is not uniform in the axial direction, and the downstream side becomes faster and the air volume is concentrated. As a result, in order to obtain the target humidification amount, it is necessary to increase the axial dimension more than necessary.

  As shown in FIG. 5A, when the fan 6 is arranged on the upstream side in the axial direction of the vaporization filter 11, the filter material 32 of the vaporization filter 11 is generated by the wind blown in the circumferential direction of the fan 6 and the wind flowing downstream. The wind is almost uniformly applied to the entire length in the axial direction, and the humidification effect is improved.

As described above, in this embodiment, since the fan 6 is provided on the upstream side with respect to the rotation center axis direction of the vaporization filter 11, the air blown outward from the fan 6 is an outer periphery orthogonal to the rotation center axis 6A of the fan 6. It is dispersed into a part blown in the direction and a part flowing downstream, and it can pass through the wide range of the vaporization filter 11 almost uniformly, and the liquid contained in the vaporization filter 11 can be efficiently vaporized. It is possible to obtain a highly efficient humidifier by uniformizing the wind speed distribution.

  Further, since the axial length of the fan 6 is more than one half of the axial length of the filter material 32, the air flowing downstream of the fan 6 hits a portion less than half of the downstream side to humidify. A working air can be formed.

  In addition, this invention is not limited to the said Example, A various change is possible in the range which does not deviate from the meaning of this invention. For example, the positional relationship between the fan 6 and the vaporization filter 11 in the second embodiment may be applied to the first embodiment, and the features in each embodiment may be appropriately combined with those in another embodiment.
