Description

  The present invention relates to a humidifying device that humidifies a room by passing air through a humidifying filter containing moisture.

  Conventionally, as an example of this type of humidifier, a part of the humidifying filter is always immersed in the water tank, and the accumulated water is sucked up by the humidifying filter, and a detachable water supply tank that always supplies water to the water tank is provided. A humidifier is known (see, for example, Patent Document 1).

  The humidifier includes a main body case having an intake port and an exhaust port, a blower for circulating the blown air through a blower passage formed by communicating the suction port and the blowout port, a water tank for supplying water from a water supply tank, and a water tank And a humidifying filter provided so that the lower part is always immersed in the stored water.

  Then, when the blown air circulated by the blowing means passes through the humidification filter, the blown air is humidified by passing through the humidification filter that sucks up the water stored in the water tank, and is supplied to the room from the outlet. .

  However, the humidification filter sucks up the accumulated water and vaporizes only the water, so the water in the tank of the humidifier is in proportion to the usage time and the amount of water used, so-called scale components such as calcium, magnesium, and dust. It gets dirty. As a result, it is humidified with dirty water, the scale component concentration further increases, the scale is deposited on the humidification filter, and clogging reduces the water absorption amount and the air volume of the blown air. Cause a decline. For this reason, it is necessary to throw away the water of a tank regularly.

JP 2011-21797 A

  In the conventional example, when a humidifier is used for a long time, the scale component concentration of the water in the water tank is likely to precipitate on the humidification filter, and the water absorption amount and the air flow rate of the blown air are clogged. Decreased, leading to a decrease in the amount of humidification. Therefore, conventionally, it has been necessary to periodically transport the water tank to a drainage facility and drain it so that the concentration of the scale components in the water tank does not increase.

  Therefore, the present invention solves the above-described conventional problems, and an object thereof is to reduce the decrease in the humidification amount by decreasing the rate of increase in the scale component concentration.

  In order to achieve this object, the present invention includes a main body case having an intake port and an exhaust port, and a blower unit, a humidifier, and a humidifier in the main body case, which are blown from the intake port to the exhaust port. A water tank at the lower part of the humidifying filter, a removable water supply / drainage tank at the lower part of the water tank, and a water supply means for supplying water from the water supply / drainage tank to the water tank. When the water supplied to the water tank by the water supply means includes a notch, the water is drained to the water supply / drainage tank through the notch when the predetermined amount of water is exceeded. Is achieved.

  According to the present invention, a detachable water supply / drainage tank is provided at the bottom of the water tank, water supply means for supplying water from the water supply / drainage tank to the water tank is provided, the water tank is provided with a notch, and the water supply means The water supplied to the aquarium is drained to the water supply / drainage tank through the notch when the predetermined amount of water is exceeded, so that the water whose scale component concentration has increased by the humidification operation is drained to the water supply / drainage tank. Thus, water with a low scale component concentration in the water supply / drainage tank is newly supplied. Thereby, the raise of the scale component density | concentration in the said water tank can be suppressed, and the effect that the fall of the humidification amount can be reduced can be acquired.

  The humidifying device according to claim 1 of the present invention includes a main body case having an intake port and an exhaust port, and a blower unit, a humidifying filter, and a fan passage in the main body case for blowing air from the intake port to the exhaust port. Provided with a water tank at the lower part of the humidifying filter, a detachable water supply / drainage tank at the lower part of the water tank, a water supply means for supplying water from the water supply / drainage tank to the water tank, and a notch in the water tank. The water supplied to the water tank by the water supply means is drained to the water supply / drainage tank through the notch when the amount of water exceeds a predetermined amount. As a result, the water whose scale component concentration has been increased by the humidifying operation is drained to the water supply / drainage tank, and the water with a low scale component concentration in the water supply / drainage tank is newly supplied, so that the scale component concentration in the water tank, etc. The increase is suppressed and the decrease in the humidification amount is reduced.

  The water supply means may be provided with a control means for stopping operation while leaving a predetermined amount of water in the water supply / drainage tank. Thereby, the place where the water whose scale component concentration has increased when the operation is stopped is not only in the water tank but also in the water supply / drainage tank, so the scale component concentration in the water tank is low when the operation is stopped. By discarding the remaining water in the water supply / drainage tank at the time of water absorption, the increase in the scale component concentration in the water tank when used for a long time stops at a constant value, and the scale does not easily deposit on the humidification filter. There is an effect that the decrease is reduced.

  Further, the water supply means may be configured to supply water separated from the bottom surface of the water supply / drainage tank by a predetermined distance to the water tank. Thereby, the water which existed in the lower part of the said water supply / drainage tank at the time of an operation stop will remain in the said water supply / drainage tank. Since the scale component is heavier than water and accumulates in the lower part in the water supply / drainage tank, more scale component is accumulated in the water supply / drainage tank when the operation is stopped. By discarding the remaining water in the water supply / drainage tank at the time of water absorption, the concentration of the scale component stored in the water tank becomes lower in the case of long-term use, and the effect of reducing the decrease in the humidification amount is achieved.

  Further, the water amount in the water supply / drainage tank when the operation by the control means is stopped may be larger than the water amount in the water tank. As a result, the amount of water discarded at the time of water supply becomes larger than the amount of water in the water tank, so that the concentration of scale components in the water tank even when used for a long period of time is Since the scale component concentration does not increase and the scale deposited on the humidifying filter is about the same, the amount of humidification is reduced to the same extent as when the drainage operation is performed each time.

  Further, a partition for separating the water drained from the notch into the water supply / drainage tank and the water supplied from the water supply / drainage tank to the water tank is provided, and at the upper part of the partition, from the notch The water drained to the water supply / drainage tank may be configured to communicate with the water supplied from the water supply / drainage tank to the water tank. As a result, most of the scale components are accumulated in the lower part of the drainage space, which is the side drained into the water supply / drainage tank from the notch, and water with a low scale component concentration is supplied to the water tank from the upper part of the partition part. By entering the water supply space on the side, water with a lower scale component concentration is supplied to the water tank, and an increase in the scale component concentration in the water tank is suppressed, and a decrease in the humidification amount is reduced. There is an effect.

  Further, the water supply means is provided with a water supply speed control means, the water supply speed control means is fast until the water amount in the water tank reaches a predetermined water amount, and after the water amount in the water tank exceeds the predetermined water amount. You may make it the structure of making it late. By reducing the water supply speed after the predetermined amount of water has accumulated in the water tank, the water supply amount is reduced, and the amount of water drained from the water tank to the water supply / drainage tank is also reduced. As a result, the drainage space partitioned by the partition becomes full, and it takes time for the drainage with a large scale component to flow into the water supply space from above, so that the concentration of the scale component in the initial tank is increased. It is suppressed, and there is an effect that the amount of humidification is less likely to occur.

  Moreover, it is good also as a structure which provided the partition part so that the water drained to the said water supply / drainage tank from the said notch part and the water supplied to the said water tank from the said water supply / drainage tank may not be mixed. As a result, the drainage from the water tank is not used again as water for humidification, and the water supplied from the water supply / drainage tank to the water tank is always water before the concentration of the scale component is increased. There is an effect that the increase in the concentration of the scale component is suppressed and the decrease in the humidification amount is reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIG. 1 and FIG. 2, the humidifying device of the present embodiment blows air from the air inlet 1 to the air outlet 2 in the main body case 3 having the air inlet 1 and the air outlet 2. The air blowing path is provided with the air blowing means 4 and the humidifying means 5.

  The main body case 3 has a substantially cubic shape, and is provided with a substantially horizontally-long square intake port 1 on the back side surface and a substantially horizontally long exhaust port 2 on the back side of the top surface.

  The humidifying means 5 is formed of a cylindrical humidifying filter 6 and a rotating means (not shown) for rotating the humidifying filter 6. A water tank 7 containing water is provided below the humidifying means 5. A part of the periphery of the humidifying filter 6 is immersed in the water of the water tank 7.

  The water tank 7 has a substantially box shape with an open top surface, is located on the upper part of a flat water tank support portion 7 a provided on the inner side wall of the main body, and can be pulled out from the back side of the main body case 3 to the center of the main body case 3. A humidifying filter mounting portion 6 a that is slidably mounted and mounts the humidifying filter 6 is provided.

  The humidifying filter 6 has a cylindrical shape, is rotatable on the humidifying filter mounting portion 6a of the water tank 7, and is mounted so that the rotation axis direction is a horizontal direction. A gear is provided on one side of the circular side surface portion of the humidifying filter 6, and the rotational force of the electric motor serving as a rotating means is transmitted to the gear, so that the humidifying filter 6 rotates.

  In such a configuration, the air in the room sucked from the air inlet 1 of the main body case 3 by the air blowing means 4 passes through the humidifying filter 6. The air humidified by the humidifying filter 6 is exhausted from the exhaust port 2 of the main body case 3 into the room.

  A feature of the present embodiment is that a detachable water supply / drainage tank 8 is provided at the bottom of the water tank 7, water supply means 9 for supplying water from the water supply / drainage tank 8 to the water tank 7 is provided, and the water tank 7 is provided with a notch 10; The water supplied to the water tank 7 by the water supply means 9 is drained to the water supply / drainage tank 8 through the notch 10 when the predetermined amount of water is exceeded.

  The water supply / drainage tank 8 has a substantially box shape that is slightly larger than the water tank 7 whose top surface is open. A water supply means 9 is mounted on the back side where the water tank 7 is connected to the water supply / drainage tank 8. It is slidably provided so that it can be pulled out from the back side of the case 3.

  As shown in FIG. 3, the notch 10 is a substantially U-shaped recess provided on the upper front side wall surface of the water tank 7.

  With such a configuration, when water is supplied to the water tank 7 by the water supply means 9 and the water surface position in the water tank 7 becomes higher than the notch 10, the water in the water tank 7 is notched 10. Drained from. This drained water is water whose scale component concentration has increased due to the humidification operation, and the water supplied from the opposite side of the notch 10 by the water supply means 9 is the water in the water supply / drainage tank 8 and the scale component concentration. Is lower than the water in the water tank 7, the increase in the scale component concentration in the water tank 7 is suppressed.

  Further, the water supply means 9 is provided with a control means 11 for stopping the operation while leaving a predetermined amount of water in the water supply / drainage tank 8. Since the control means 11 places the water where the scale component concentration has increased when the operation is stopped, not only in the water tank 7 but also in the water supply / drainage tank 8, for example, the scale component concentration in the water tank 7 at the time of the first operation stop is The amount of remaining water at the time of stoppage is lower than the scale component concentration of the humidifier that does not have a drainage mechanism from the water tank. If the humidification operation is continued thereafter, the concentration of the scale components in the water tank of the humidifier that does not have a mechanism for draining water from the water tank continues to increase in proportion to the amount of water supplied unless the water is drained. On the other hand, when the water with high scale component concentration remaining in the water supply / drainage tank 8 is discarded, new water with low scale component concentration is pumped into the water supply / drainage tank, and the humidification operation is started, immediately after the start, the scale component concentration is low in the water tank 7. Since water is supplied and water with high scale component concentration in the water tank 7 is drained, the scale component concentration in the water tank 7 becomes low, and then the scale concentration in the water tank 7 and the water supply / drainage tank 8 becomes the same. The scale component concentration increases in both the water tank 7 and the water supply / drainage tank 8, but when the first operation is stopped, the stored water in the water supply / drainage tank 8 is discarded and replaced with new water. The concentration of the scale component at the time of stopping is lower than that of a humidifier without a drainage mechanism. By repeating this operation, the scale component in the water tank 7 does not easily rise above a certain value even after long-term use, and this value varies depending on the amount of water remaining in the water supply / drainage tank 8.

  Further, the control means 11 is for the water supply means 9 to supply the water tank 7 with water separated from the bottom surface of the water supply / drainage tank 8 by a predetermined distance. That is, the water suction port of the water supply means 9 is installed at a predetermined distance from the bottom surface of the water supply / drainage tank 8 so that the water collected near the bottom of the water supply / drainage tank 8 is not sucked. This is a configuration. Since the scale component is heavier than water and accumulates in the lower part of the water supply / drainage tank 8, the water present in the lower part of the water supply / drainage tank 8 when the operation is stopped has a higher concentration of the scale component than the water tank 7, and when the operation is stopped. Many scale components accumulate in the water supply / drainage tank. By discarding the remaining water in the water supply / drainage tank 8 at the time of water supply, the concentration of the scale component stored in the water tank 7 in the case of long-term use becomes low.

  Further, the amount of water in the water supply / drainage tank 8 when the operation by the control means 11 is stopped is larger than the amount of water in the water tank 7. As shown in FIG. 3, by increasing the amount of remaining water in the water supply / drainage tank 8, the concentration of scale components in the water tank 7 when used for a long period of time decreases, and the amount of residual water in the water supply / drainage tank 8, that is, the amount of water discarded during water supply is reduced. When the amount of water in the aquarium 7 is greater than the amount of water in the aquarium 7, the concentration of the scale components in the aquarium 7 is drained from the aquarium using a humidifier that does not have a drainage mechanism. It can only be increased to the same level as the scale component concentration in the tank when the operation is stopped due to drought.

  In addition, a partition 12 is provided for separating water drained from the notch 10 into the water supply / drainage tank 8 and water supplied from the water supply / drainage tank 8 to the water tank 7, and the notch 10 is provided above the partition 12. Further, the water drained into the water supply / drainage tank 8 and the water supplied to the water tank 7 from the water supply / drainage tank 8 communicate with each other.

  The partition portion 12 has a substantially horizontally long rectangular shape, and is provided so as to partition the water supply / drainage tank 8 into a drainage space 13 in which water drained from the water tank 7 accumulates and a water supply space 14 into which water to be supplied to the water tank 7 is stored. The height is lower than the height of the wall surface of the water supply / drainage tank 8, and water can pass through the upper part thereof.

  Thereby, the water drained into the water supply / drainage tank 8 from the notch 10 enters the drainage space 13 in the water supply / drainage tank 8, and most of the scale components accumulate in the lower part thereof. Water overflowing from the drainage space 13 due to drainage from the aquarium 7 enters the water supply space 14 from the upper part of the partitioning part 12, and the water is water in the upper part of the front side space, and the scale component concentration is lower than that in the lower part. It is. That is, the water supplied to the aquarium 7 is the water in the water supply space 14, and the scale component concentration is lower than that without the partition 12, so that water with a lower scale component concentration is supplied to the aquarium 7. Thus, an increase in the concentration of scale components in the water tank 7 is suppressed.

  It should be noted that the place where water is supplied during water supply may be both the space 13 for drainage and the space 14 for water supply, or may be only the space 14 for water supply. If the drainage space 13 is empty at the start of operation, it takes time until the water overflows from the drainage space 13 due to drainage from the water tank 7, and the water supply space 14 during which the scale component concentration does not increase. The clean water inside is supplied to the water tank 7. Thereby, the raise of the scale component density | concentration in the water tank 7 is suppressed.

  Further, the water supply means 9 is provided with a water supply speed control means 15, and this water supply speed control means 15 is fast until the water amount in the water tank 7 reaches the predetermined water amount, and the water amount in the water tank 7 exceeds the predetermined water amount. It is the structure of making it late. At the start of operation when the water tank 7 is empty, it is necessary to quickly accumulate a predetermined amount of water in the water tank 7 so that the humidification operation can be performed quickly. After that, since it is sufficient to supply only the amount of water necessary for humidification, the amount of water supplied to the water tank 7 is reduced by slowing the water supply speed after the predetermined amount of water has accumulated in the water tank 7. The amount of water drained into the water supply / drainage tank 8 also decreases. That is, the water supply speed until the water amount in the water tank 7 reaches the predetermined water amount is faster than the water supply speed after the water amount in the water tank 7 exceeds the predetermined water amount. As a result, the drainage space 13 partitioned by the partitioning portion 12 is filled with water, and it takes time until the drainage with a large scale component flows into the water supply space 14 from the upper portion of the partitioning portion 12. An increase in scale component concentration in the initial stage can be suppressed.

  Moreover, it is good also as a structure provided with the electrolysis unit which electrolyzes the water in a water tank and produces | generates the electrolyzed water containing an active oxygen seed | species (not shown). When an electrolysis unit is provided for the purpose of sterilization in the water tank, if the operation is continued for a relatively long period of time, the scale components will be concentrated and become a scale when electrolyzed water is generated and deposited on the electrode. However, there is a problem in that the amount of water supply and the air volume of the blown air are reduced by clogging the humidifying filter, resulting in a decrease in the humidification amount. However, the provision of the water supply / drainage tank can suppress the decrease in the humidification amount even when there is an electrolysis unit.

(Embodiment 2)
4, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted. The difference from the first embodiment is a partition 12a and a water supply / drainage tank lid 8a shown in FIG.

  In FIG. 4, the water supply means 9 is provided with a water supply speed control means 15, and this water supply speed control means 15 is fast until the amount of water in the aquarium 7 reaches a predetermined amount of water, and the amount of water in the aquarium 7 reaches a predetermined amount of water. In other words, the water supply speed until the water amount in the water tank 7 reaches the predetermined water amount is faster than the water supply speed after the water amount in the water tank 7 exceeds the predetermined water amount. A partition 12a is provided to separate the drainage space 13 into which water drained into the water supply / drainage tank 8 from the notch 10 and the water supply space 14 into which water to be supplied from the water supply / drainage tank 8 to the water tank 7 is separated. By providing the water supply / drainage tank lid 8a so as to be in contact with the portion 12a, the drainage space 13 and the water supply space 14 are completely separated.

  After normal humidification operation starts by supplying a predetermined amount of water to the aquarium 7, the water supply speed is slowed down, and the amount of water necessary for humidification is supplied to the aquarium 7, so that the drainage in the water supply / drainage tank 8 from the aquarium 7 The amount of water drained into the space 13 is limited. The partition portion 12a is provided at a position where the size of the drainage space 13 is larger than the amount drained from the water tank 7 by one water supply.

  By completely partitioning the drainage space 13 and the water supply space 14 with the partition part 12a, it becomes the same state as draining a part of the water in the water tank every time with a humidifier without a drainage mechanism from the water tank, An increase in scale component concentration in the water tank 7 is suppressed, and a decrease in the humidification amount is reduced.

  The humidifying device according to the present invention is provided with a detachable water supply / drainage tank at the bottom of the water tank, provided with water supply means for supplying water from the water supply / drainage tank to the water tank, and provided with a notch in the water tank, the water supply means When the water supplied to the water tank is discharged to the water supply / drainage tank through the notch when the predetermined amount of water is exceeded, the water whose scale component concentration is increased by the humidification operation is the water supply / drainage tank. The water having a low scale component concentration in the water supply / drainage tank is newly supplied. Thereby, the raise of the scale component density | concentration in the said water tank is suppressed, and the fall of the humidification amount is reduced. Therefore, utilization as a humidifier for home use or office use is useful.
