Description

  The present invention relates to a humidifier for preventing indoor drying.

  As shown in FIG. 7, the conventional general humidifier includes a water supply tank 30 that is detachable from the main body, and a certain amount of water supplied from the water supply tank 30 is stored in the water tank section 31. . A vaporization filter 32 is installed in the water tank unit 31, and the vaporization filter 32 absorbs water from the water tank unit 31 to wet it, and humidifies air by blowing dry air in the room to the vaporization filter 32. The humidified air is blown out to humidify the room.

  And when water runs out, since only the water supply tank 30 can be removed from the main body and water can be supplied, it is excellent in convenience. Therefore, a humidifier using the water supply tank 30 is generally used.

  By the way, in home appliances such as humidifiers, it is one of the items that users consider when purchasing, because it is compact and does not take place, so downsizing of the device has always been an issue. Yes. However, in the humidifier as described above, it is difficult to reduce the size of the main body because a space for installing the water supply tank 30 is required inside the main body.

  Moreover, since the structure of the water supply tank 30 and the water tank part 31 is complicated, there is a problem that the number of parts is large and it is difficult to reduce the manufacturing cost. Furthermore, the water supply tank 30 and the water tank part 31 are always in contact with water. Parts require regular maintenance, but cleaning every corner of a complex structure has been cumbersome.

  On the other hand, there is a humidifier that also serves as a water supply tank in the water tank part, and since a separate water supply tank is not required, the main body can be miniaturized (Patent Documents 1 and 2).

  However, in Patent Document 1, since the main body has an integral structure, it is difficult to remove internal parts, and there is a problem that cleaning cannot be performed because the hand cannot reach the inside of the water tank. Therefore, in Patent Document 2, the above-mentioned problem was solved by making the upper and lower parts separable and fixing with the locking pieces and the locking holes, but in order to divide the upper and lower parts, the locking pieces must be removed. If the frequency of water supply is high, the trouble of removing the locking piece may be felt troublesome.

It is a front view of the lower casing of the present invention. It is right side sectional drawing of the humidifier of this invention. It is the figure which showed the conventional humidifier.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode of the present invention, which is considered preferable, will be briefly described by showing the effects of the present invention.

  The humidifier of the present invention includes a separable electrical unit and a vaporization unit, and the main body is configured by placing the electrical unit on the vaporization unit, and the height of the main body with the electrical unit placed on the vaporization unit. The ratio of the height of the vaporization unit in the range of 2/3 to 3/4.

  Specifically, when the electrical unit is placed on the vaporization unit, the upper casing that forms the electrical unit is fitted so as to have a predetermined overlap inside the lower casing that forms the vaporization unit, and the electrical unit is mounted on the vaporization unit. Locked and fixed. Therefore, since a locking piece or the like is not required as in the prior art, when supplying water, the electrical unit can be removed by lifting the electrical unit with a hand on the upper part of the main body, and the upper and lower parts can be easily divided. be able to.

  And when moving a humidifier, a main body can be carried by raising a hand near the center of a main body. In the vicinity of the center of the main body, since the vaporization unit and the electrical unit overlap, there is sufficient strength, so it can be carried stably. That is, the electrical unit can be removed and the main body can be carried simply by changing the position where the hand is attached to the main body.

  Note that if the proportion of the vaporization unit relative to the main unit is too high, there will be less parts to be removed when removing the electrical unit, and it will be difficult to lift without a handle, etc. If it is low, the stability when the electrical unit is placed on the vaporization unit may be impaired, and the electrical unit may become unstable when it is carried. Therefore, by changing the height of the vaporization unit from two-thirds to three-fourths of the height of the main unit, it is necessary to secure a portion to which a hand is attached when removing the electrical unit and eliminate the need for a handle while carrying it. It becomes a humidifier with excellent stability.

  Moreover, since the blower outlet is provided by opening a part of the casing, the strength of the part is reduced by providing the blower outlet, but is reinforced by overlapping the upper casing and the lower casing. Can maintain strength and does not impair stability during carrying.

  Further, by forming a rib around the outlet of the lower casing, the strength can be further increased, and the upper casing can be locked to the lower casing by bringing the upper casing into contact with the upper end of the rib.

  Moreover, an air passage is formed by providing an air suction port on the top surface of the upper casing and providing a communication port communicating with the vaporization unit on the bottom surface facing the suction port. Since no electrical parts are placed in this air passage, when water is poured from the suction port, this water is supplied to the vaporization unit through the communication port. Is also possible.

  An embodiment of the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the main body 1 of the humidifier is composed of an upper electric unit 2 and a lower vaporization unit 3 that can be divided, and the outer shape of the humidifier body 1 has a substantially cylindrical shape with the upper part slightly widened.

  2 and 3, in the electrical unit 2 at the top of the main body 1, the upper casing 10 is composed of the frame main body 11 and the top plate 12, and the blower 15 including the sirocco fan 13 and the motor 14 is accommodated in the upper casing 10. The blower 15 is fixed to the frame body 11 by a fan casing 16. A power switch 17 for instructing the operation of the humidifier is provided at a position corresponding to the front of the main body of the upper casing 10, and a power cord 18 for supplying power to the motor 14 extends from the back.

  Further, the top plate 12 of the upper casing 10 is provided with a plurality of suction ports 19 for taking indoor air into the main body 1 by the rotation of the sirocco fan 13 along the vicinity of the periphery thereof.

  The frame main body 11 includes a large-diameter upper frame main body 11a and a small-diameter lower frame main body 11b formed below the upper frame main body 11a. A step portion is provided at the boundary between the upper frame main body 11a and the lower frame main body 11b. 11c.

  The lower frame main body 11b has a shape in which a part thereof is cut out and opened, and this opening is provided in consideration of a direction in which humidified air is blown out from a blowout port 22 described later. In order to blow out the humid air in the substantially front direction, a range of about 90 degrees is opened from the front of the main body 1 to the left in accordance with the rotation direction of the counterclockwise sirocco fan 13.

  A communication port 11 d communicating with the vaporizing unit 3 is formed on the bottom surface of the upper casing 10 at a position facing the suction port 19 provided on the top plate 12. The blower 15 has a shape and size that fits in the center of the bottom so as not to block the communication port 11d, and no electrical components are disposed between the suction port 19 and the communication port 11d.

  4 and 5, the vaporization unit 3 at the lower part of the main body 1 includes a lower casing 20 as a water tank part that stores water therein, a vaporization filter 21 that is installed in the lower casing 20 and sucks up water in the lower casing 20, It is comprised from the blower outlet frame 23 provided with the blower outlet 22 which blows off the humidified air which passed the vaporization filter 21 indoors.

  The lower casing 20 has a water level window 24 for confirming the water level in the lower casing 20 from the outside on the side wall, and a plurality of fixing pieces 25 for positioning the vaporization filter 21 on the bottom surface and water supply on the side surface. In this case, a water level line 26 is provided as an indication of the water level.

  The vaporizing filter 21 has a hollow cylindrical shape at the center, and is fixed to the center of the lower casing 20 by a fixing piece 25 and is prevented from being deformed.

  The blower outlet frame 23 is formed integrally with the lower casing 20 and has a shape including a plurality of ribs 27 over the entire circumference of the lower casing 20. And the blower outlet frame 23 is provided with the blower outlet 22 so that humid air may be blown off in the substantially front surface of the main body 1. This blower outlet 22 is arranged so that the blower 15 is located above the lower end of the blower outlet 22 when the electrical unit 2 is placed on the vaporization unit 3, and the blower 15 is not immersed in water. It is like that.

  As shown in FIG. 6, when the electrical unit 2 is placed on the vaporization unit 3, the frame body 11 of the upper casing 10 is fitted inside the lower casing 20, and the outlet frame 23 and the upper casing of the lower casing 20 are fitted. 10, the lower frame body 11 b overlaps, and the stepped portion 11 c comes into contact with the upper end of the rib 27, whereby the electrical unit 2 is locked to the vaporizing unit 3. At this time, the height (H3) of the vaporizing unit 3 is set to a range of two-thirds to three-fourths of the height (H1) of the main body 1, and in the present embodiment, the height (H3) is about two-thirds. It has become.

  Thus, since the vaporization unit 3 and the electrical unit 2 are fitted with a predetermined overlap, the vaporization unit 3 can be stabilized only by being placed on the electrical unit 2. Therefore, since there is no need to provide a locking piece or the like as in the prior art, the vaporization unit 3 and the electrical unit 2 can be easily attached and detached.

  In addition, since the blower outlet frame 23 is partially opened and the blower outlet 22 is provided, the strength is slightly reduced. However, the blower outlet frame 23 has a lower frame body when the electrical unit 2 is placed. Since it overlaps with 11b and is reinforced by the lower frame main body 11b from the inside to increase the strength, it does not become unstable when the main body 1 is carried.

  In the above configuration, when water is supplied to the humidifier, the electrical unit 2 is lifted and removed from the main body 1, and water is poured into the vaporizing unit 3 (lower casing 20). Since the lower casing 20 is provided with a water level line 26 that serves as a guide for the water level, water is supplied so as not to exceed the water level line 26.

  Since the power cord 18 extends from the electrical unit 2, if the electrical unit 2 is removed from the main body 1, the vaporization unit 3 can be carried freely even with the power cord 18 inserted into the outlet, and only the vaporization unit 3 can be carried. You can take water to your home water supply.

  The electrical unit 2 can be easily separated from the main body 1 simply by placing the hand on the upper frame main body 11a and pulling it up by the height of the lower frame main body 11b overlapping the air outlet frame 23. That is, if there is a space corresponding to the height of the lower frame main body 11b at the top of the main body 1, the electrical unit 2 can be removed on the spot without moving the main body 1, so that the height of the inside of the shelf is limited. It will be possible to install it in a designated space. Moreover, by making the main body 1 into a substantially cylindrical shape that spreads upward, it becomes easier to lift the hand when the hand is attached to the upper frame main body 11a.

  When the water supply is completed, when the electrical unit 2 is placed on the vaporizing unit 3, the lower frame body 11 b of the upper casing 10 is fitted inside the lower casing 20, and the stepped portion 11 c abuts on the rib 27, thereby the vaporizing unit. The electrical unit 2 is locked and fixed to 3. At this time, if the blower 15 accommodated in the electrical unit 2 is immersed in water, it may cause a failure. However, the blower 15 is located higher than the water level stored in the lower casing 20 and should be used safely. Can do.

  Up to this point, the procedure for removing the electrical unit 2 and supplying water has been described. However, the water can be supplied from the suction port 19 on the top surface of the top plate 12 without removing the electrical unit 2. In this case, when water is poured from the suction port 19 using a medicine can or the like, the water is supplied from the suction port 19 to the lower casing 20 of the vaporization unit 3 through the communication port 11d. That is, the suction port 19 provided as a ventilation path and the communication port 11d are used as a water supply passage, and since no electrical parts are arranged between the suction port 19 and the communication port 11d, water is supplied from the suction port 19. Even if it is poured, the electrical parts will not get wet.

  When the main body 1 is moved, the main body 1 can be lifted by placing a hand on the outlet frame 23 near the center of the main body 1 (below the upper frame main body 11a). At this time, if it is below the upper frame main body 11a, you may attach a hand to the lower casing 20 below the blower outlet frame 23, but the blower outlet frame 23 is high in strength because it overlaps the lower frame main body 11b, Since the rib 27 is formed in the blower outlet frame 23, a finger is caught on the rib 27, so that it is easier to carry than if the hand is attached to the lower casing 20. The rib 27 not only makes it easy to carry, but also has a role to prevent foreign matters from entering from the air outlet 22.

  In order to make it easy to remove the electrical unit 2 and to move the main body 1, the height (H3) of the vaporizing unit 3 is in the range of two-thirds to three-fourths of the height (H1) of the main body 1. It is desirable that This is because if the proportion occupied by the vaporizing unit 2 is too high, the upper frame body 11a to be handled when removing the electrical unit 3 is reduced, making it difficult to lift. In order to solve this problem, it is necessary to provide a handle by making a dent in the upper frame body 11a. However, if the handle is provided, not only will the cost increase, but also the ventilation from the suction port 19 to the communication port 11d. Narrowing the path may affect ventilation efficiency. If a rotary handle is provided, a space for rotating the handle is required around the body 1 and the height of the shelf is limited. It can no longer be placed. On the other hand, if the proportion of the vaporization unit 2 is low, the main body 1 has a shape in which the upper part is widened, so that the stability when the electrical unit 3 is placed on the vaporization unit 2 is deteriorated. Because it becomes unstable.

  Further, since the lower casing 20 and the vaporization filter 21 that are always in contact with water are attached with scale and scale, regular maintenance is required. However, the vaporization unit 3 can be divided from the main body 1 only by lifting the electrical unit 2. The vaporization filter 21 can be easily taken out. The lower casing 20 is provided with a fixing piece 25 for the vaporization filter 21 on the inner bottom surface. However, the lower casing 20 has a shape with little unevenness, and can be washed thoroughly once the vaporization filter 21 is removed. Can be washed.

  Next, the operation of the humidifier in the above configuration will be described.

  First, when the power switch 17 is turned on, power is supplied to the motor 14 and the motor 14 is activated. The power switch 17 is a seesaw type and can be switched between strong and weak operation modes in addition to operation stop, and the rotation speed of the motor 14 is set according to the operation mode.

  When the motor 14 is operated, the sirocco fan 13 is rotated, and by the rotation of the sirocco fan 13, indoor air flows into the main body 1 from the suction port 19 provided in the top plate 12 of the upper casing 10. In FIG. 6, the white arrow represents dry air in the room, and the air that flows in from the suction port 19 passes through the communication port 11 d and flows into the vaporization unit 3.

  Since the vaporization unit 3 is provided with a vaporization filter 21 that sucks and wets the water stored in the lower casing 20, the air that has flowed into the vaporization unit 3 is sucked into the center from the outer periphery of the vaporization filter 21 and vaporized. When passing through the filter 21, it becomes humidified air containing moist air. The black arrow in FIG. 6 represents humidified air, and the humidified air is pulled upward from the center of the vaporizing filter 21 by the suction force of the sirocco fan 13 and blown out from the air outlet 22 to the front of the main body to humidify the room. Become.

  During the operation of the humidifier, the motor 14 of the blower 15 is cooled by the air flowing from the suction port 19. This air is dry air in the room, and the humidified air that has passed through the vaporizing filter 21 does not flow into the periphery of the motor 14. It is possible to extend the life by suppressing deterioration of the motor 14 due to the humidity.

  Further, by blowing the humidified air to the substantially front surface of the main body 1, it becomes possible to install a humidifier even in a place where the side surface of the main body 1 is sensitive to moisture. And since it inhales from the upper surface, it can inhale even if the side surface and back surface of the main body 1 are blocked. For these reasons, it can be installed in places where it has conventionally been unsuitable as a place for installing a humidifier, such as in a bookshelf.
