Description

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

  Conventionally, as an example of this type of humidifier, there has been known a system called a vaporization type in which air is supplied to a vaporization filter containing moisture and humidified (for example, Patent Document 1).

  FIG. 5 shows a cross section of this vaporizing type humidifier. The main body is provided with a water tank (not shown) that is detachable from the main body, and a certain amount of water supplied from the water tank is stored in the water tank section 21. The vaporization filter 22 is installed in the water tank unit 21, and the vaporization filter 22 absorbs water in the water tank unit 21 and is moistened.

  The indoor dry air is taken in from the suction port 24 by the rotation of the sirocco fan 23 and blown to the vaporization filter 22. The dry air passes through the vaporization filter 22 and becomes humidified air. The inside is humidified by blowing out from the room.

JP 2007-162965 A

  In household electrical appliances such as humidifiers, compactness and no storage space is one of the items that users consider when purchasing, and therefore downsizing of devices has always been a problem.

  However, the conventional humidifier has a structure in which the air flowing in from the suction port once flows downward until it reaches the vaporization filter, so the distance from the suction port to the vaporization filter becomes longer, and this space becomes larger. It was preventing the miniaturization.

  Moreover, since the sirocco fan is arrange | positioned above the vaporization filter, there also exists a problem that the height of a vaporization filter will be restrict | limited. In the vaporization type humidifier, since the area of the vaporization filter affects the humidification amount, it is difficult to increase the vaporization area with such an arrangement, and it is difficult to increase the humidification capacity.

  Therefore, in order to increase the humidification capacity without changing the size of the main body, measures such as changing the vaporization filter to a double pleated one can be considered, but the double pleated vaporization filter has a large pressure loss, and it can be used during operation. A new problem arises that the noise becomes louder.

  An object of the present invention is to solve the above-described problems, and an object of the present invention is to provide a humidifier that can reduce the size of the main body without impairing usability, and does not take a place.

The present invention includes a water tank that is detachably attached to a main body, a water tank part that temporarily stores water supplied from the water tank, a substantially rectangular parallelepiped vaporization filter that vaporizes water in the water tank part, and a sirocco The fan comprises a fan and a motor having a smaller diameter than the sirocco fan and blows air to the vaporizing filter, a suction port for taking in indoor air, and a blower outlet for blowing out humidified air, and the suction port is one of the vaporization filters. provided close to the surface Rutotomoni a humidifier, characterized in that a said motor above the vaporization filter.

  By comprising as mentioned above, while being able to reduce a main body, the malfunction which water spills from a suction inlet is prevented, and it becomes a user-friendly humidifier.

It is an external appearance perspective view of the humidifier of the present invention. It is A-A 'sectional drawing of the humidifier of this invention. It is B-B 'sectional drawing of the humidifier of this invention. It is a disassembled perspective view of the humidifier of this invention. It is sectional drawing of 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 water tank that can be attached to and detached from the main body, a water tank part that stores water from the water tank, a substantially rectangular parallelepiped vaporization filter that vaporizes water in the water tank part , a sirocco fan, and a sirocco fan that has a smaller diameter. comprising a composed blower motor is, suction port for taking the indoor air is provided in proximity to one surface of the vaporizing filter Rutotomoni, it is arranged motor above the vaporization filter.

  In other words, the indoor dry air taken into the main body from the suction port immediately flows into the vaporization filter, and by eliminating the ventilation path between the vaporization filter from the suction port, the main body is eliminated. Can be miniaturized.

  In addition, a certain amount of water is stored in the water tank part where the vaporization filter is provided, and if the ventilation path between the suction port and the vaporization filter is eliminated, the water will be sucked in when the water surface is undulated. There is a possibility that water in the water tank portion may spill out from the mouth, but in order to prevent this, the vaporization filter is provided close to the suction port. By configuring in this way, even if the water surface undulates and exceeds the height of the suction port, the water stays in the vaporization filter due to the surface tension of the vaporization filter, so that water spills out from the suction port. Does not occur.

  In addition, by covering the inside of the main body of the suction port with a vaporization filter, the area where the vaporization filter is in contact with air is increased, and water does not spill out.

  Further, since the motor has a smaller diameter than the sirocco fan, the height of the vaporization filter can be increased by disposing the motor above the vaporization filter. That is, since the vaporization area can be increased without increasing the shape of the main body, it is possible to increase the humidification capability while reducing the size of the main body. Furthermore, since the motor is disposed in the air passage, the motor is cooled by the air flowing into the main body during operation, thereby preventing deterioration of the motor and extending its life, and reducing the size of the motor itself. Therefore, it is possible to further increase the area of the vaporization filter.

  Moreover, when the main body falls down, it is possible that the water stored in the water tank part flows into the electrical equipment part. However, since the electrical components are provided at a predetermined distance from the surface where the water accumulates (wide surface) when the main body falls, the electrical components do not get wet even if water enters the electrical components, so there is no risk of failure. It becomes a convenient humidifier.

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

  FIG. 1 is an external perspective view of a humidifier according to the present invention. A main body 1 of the humidifier has a substantially rectangular parallelepiped shape, and a water tank 2 detachably provided on the main body 1 forms a part of the outer surface of the main body 1. doing. The side surface forming the main body 1 has wide and wide surfaces 1a and 1b and a narrow and narrow surface 1c. The wide surface 1a has a suction port 3 for taking indoor air into the main body 1. The operation switch 4 which is an electrical component is provided on the narrow surface 1c, and the air outlet 5 for releasing the air humidified in the main body 1 into the room is provided on the top surface of the main body 1.

  2 and 3 are internal cross-sectional views of the humidifier. The water tank 6 stores the water supplied from the water tank 2 with a certain amount of water, and the water stored in the water tank 6 is disposed in the water tank 6 to absorb water. Vaporizing filter 7 that gets wet, blower 8 that takes in indoor air from the suction port 3, passes through the humidified vaporizing filter 7, and discharges it as humidified air into the room through the outlet 5. A partition member 9 that forms an air passage and an electrical component 10 that accommodates electrical components are provided.

  The water tank 6 has a shape with an open top, and is slidable so that it can be pulled out from the main body 1 when the water tank 2 is removed. The water tank section 6 includes a water tank mounting section 6a for mounting the water tank 2 and a vaporization filter mounting section 6b for mounting the vaporization filter 7, and a fixed piece for fixing the vaporization filter 7 to the vaporization filter mounting section 6b. 6c is provided.

  The suction port 3 and the vaporization filter 7 are arranged at adjacent heights, and by shortening the ventilation path between the suction port 3 and the vaporization filter 7 as much as possible, the useless space is eliminated and the main body 1 is reduced in size. be able to.

  Further, the vaporization filter 7 has a substantially rectangular shape, is positioned by a fixing piece 6 c provided in the water tank portion 6, and a surface facing the suction port 3 is provided close to the suction port 3.

  That is, since a fixed amount of water is always stored in the water tank 6 where the vaporization filter 7 is provided, if the suction port 3 and the vaporization filter 7 are arranged at adjacent heights, the suction port 3 and the water tank 6 When the water surface undulates during carrying, the water in the water tank portion 6 may spill out from the suction port 3. However, even if the vaporization filter 7 and the suction port 3 are not only adjacent to each other but also provided close to each other, the surface of the vaporization filter 7 can be obtained even if the water surface undulates and exceeds the height of the suction port 3. The water stays in the vaporization filter 7 due to the tension, and the problem of water spilling out from the suction port 3 does not occur.

  The proximity here means that the suction port 3 and the vaporization filter 7 are arranged very close to each other, and in this embodiment, there is a slight gap between the suction port 3 and the vaporization filter 7. However, it may be in a close contact state without a gap. In the present embodiment, since the vaporization filter 7 is provided in the water tank portion 6, there is a gap between the suction port 3 and the vaporization filter 7 because the side wall thickness of the water tank portion 6 exists. However, the suction port 3 and the vaporization filter 7 can also be configured to be in close contact with each other by recessing the suction port 3 inward or changing the shape of the vaporization filter 7.

  And the upper end position and width | variety of the vaporization filter 7 are substantially the same as the suction inlet 3 in the state installed in the water tank part 6, and the suction inlet 3 is entirely covered with the vaporization filter 7 inside the main body. . Thereby, the area in which the vaporization filter 7 is in contact with air is maximized, and water is not spilled from the suction port 3.

  The blower 8 includes a sirocco fan 8a and a motor 8b that rotates the sirocco fan 8a. The sirocco fan 8a and the motor 8b are connected to the main body 1 in the horizontal direction with the partition member 9 interposed therebetween, and are vaporized. The motor 8 b is disposed in the main body 1 so as to be positioned above the filter 7.

  If the blower 8 is provided in the upper part of the main body 1 and the vaporization filter 7 is provided in the lower part as in this embodiment, and the blower 8 is configured to horizontally arrange the motor 8b and the sirocco fan 8a, the motor 8b is more than the sirocco fan 8a. Because of the small diameter, the height of the vaporization filter 7 can be increased by arranging the motor 8b on the vaporization filter 7. As a result, the vaporization area can be increased without increasing the shape of the main body 1, and the humidification ability can be increased while the main body 1 is kept small.

  FIG. 4 is an exploded view of the inside of the main body, and the partition member 9 includes a central partition plate 9a for partitioning the inside of the main body 1 from side to side at a substantially center, an opening 9b provided in the central partition plate 9a, A fan peripheral wall 9c provided in an arc shape is provided. Inside the fan peripheral wall 9c is a humidified air passage 9d through which the humidified air passes, and the humidified air passage 9d communicates with the opening 9b and the outlet 5. That is, the dry air in the room that has flowed into the main body 1 from the suction port 3 by the rotation of the sirocco fan 8 a becomes humidified air containing moisture when passing through the vaporizing filter 7, and this humidified air is above the vaporizing filter 7. The air passes through the periphery of the motor 8b provided in the air, flows into the humidified air passage 9d from the opening 9b, flows along the fan peripheral wall 9c, and is discharged from the blowout port 5 into the room. The white arrow in FIG. 2 represents indoor dry air, and the black arrow represents humidified air.

  When the humidified air travels from the vaporization filter 7 to the opening 9b, the humidified air passes around the motor 8b. Therefore, the motor 8b is cooled by the humidified air during operation, so that the motor 8b is prevented from deteriorating and the life is extended. be able to. Furthermore, since it is possible to reduce the size of the motor 8b itself, if the motor 8b is reduced in size, the height of the vaporizing filter 7 provided below the motor 8b can be increased, so that the humidification is achieved. It becomes possible to increase ability.

  The electrical component 10 is formed by being surrounded by the main body 1 and the partition member 9, and is provided with an operation switch 4 that is an electrical component. In other words, since the electrical part 10 is isolated from the water tank part 6, the water in the water tank part 6 does not enter the electrical part 10 to the extent that the water surface is slightly waved when the main body 1 is carried. There is no water splashing on the wiring of the switch 4. In addition, since air is sucked out by the rotation of the blower 8 and becomes negative pressure in the electrical component 10, the entry of dust and the like into the electrical component 10 is suppressed, thereby preventing the occurrence of tracking.

  Further, the operation switch 4 is mounted on the narrow surface 1c of the main body 1 at a position separated by a predetermined distance L from the wide surface 1b where the suction port 3 is not provided.

  The predetermined distance L refers to a distance that prevents the electrical component from getting wet with water even if the main body 1 falls down and the water in the water tank portion 6 flows out. That is, when the body 1 having a substantially rectangular parallelepiped shape is subjected to a force from the outside, it tends to fall down in the direction of the wide surface, and in most cases, it falls down to either the wide surface 1a or 1b. The water stored in the water tank section 6 flows out of the main body 1 from the suction port 3 even if it falls in the direction of, so that there is no fear that the operation switch 4 will get water. However, when it falls down in the direction of the wide surface 1 b, the water stored in the water tank unit 6 may flow into the electrical unit 10 from the gap of the main body 1. At this time, the height of the water surface from the wide surface 1b formed when all the water in the water tank 6 flows out and flows into the electrical component 10 is L. Therefore, if the operation switch 4 is installed at a position L away from the wide surface 1b, the operation switch 4 will not get wet with water even if the main body 1 falls, and there is no fear of causing a failure.

  Moreover, since the operation switch 4 is attached to the side surface (narrow surface 1c) of the main body 1, even if the main body 1 is splashed with water, water enters between the operation switch 4 and the main body 1 to the inside. Therefore, a special waterproofing treatment around the operation switch 4 is not necessary. Therefore, the product can be configured at low cost.
