Description

  The present invention relates to a humidifier that humidifies a room or the like, and more particularly, to a humidifier using a water supply tank.

  Conventionally, various types of humidifiers such as a vaporization type, a steam type, and an ultrasonic type have been used to humidify a room and the like, and these humidifiers often use tap water. A humidifier replenishes water in a water supply tank to increase indoor humidity. However, tap water contains minerals such as magnesium and calcium, and the room contains water containing these minerals. When the water is humidified, the mineral component contained in the water is also released at the same time, so that the mineral component may precipitate in the room and white powder may be generated.

As a countermeasure, a method of installing a filter 92 such as an ion exchange resin for filtering tap water in a water supply tank of a humidifier is often used. As shown in FIG. 4, the filter is used by being placed in a water supply tank 9 by filling a cartridge having a slit 97 on a side surface with an ion exchange resin.
An air hole 98 penetrating vertically is provided on the upper surface of the ion exchange resin cartridge, and a water-permeable net for holding the ion exchange resin is provided on the bottom surface.

  The cap 90 of the water supply tank 9 is provided with a double side wall on the tank side, and a spiral groove is provided inside each of the two side walls. In addition, the outer peripheral side wall can be screwed to the lower flange of the tank, and the inner peripheral side wall can be screwed to the ion exchange resin cartridge. Further, a valve 99 is provided at the center of the cap 90 so that water can flow out by moving upward when the water supply tank is mounted on the main body 2.

  The user fills the main body 2 with tap water in a humidification water tank. Then, the ion exchange resin of the filter passes through the slit 97 provided in the cartridge 96, and further passes through the net on the bottom surface of the cartridge to introduce water into the communication path 10.

However, when the water level in the tank exceeds the height of the cartridge as shown in FIG. In some cases, a flow occurs and the filtration efficiency is lowered by the flow of water that does not pass through the ion exchange resin.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to remove efficiently the mineral content contained in the tap water of a humidifier.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a humidifier according to the present invention. 2 is an enlarged view of a main part of FIG. 1, FIG. 3 is a sectional perspective view of a filter part used in the present invention, and FIG. 4 is a schematic view of a humidifier having a conventional structure. FIG. 5 is a plan view of a conventional filter.

(First embodiment)
As shown in FIG. 1 to FIG. 2, the humidifier of the present invention is mainly composed of a humidifier body 2, a water supply unit, and a humidification unit. The water supply unit includes a water supply tank 9 and an ion exchange resin (filter) 92, and the humidification unit includes a communication path 10, an ultrasonic vibrator 11, a mist outflow cylinder 7, and a blower fan 6.

  The humidifier body 2 is not particularly limited as long as the water supply unit and the humidification unit can be accommodated, but a part of the mist outflow cylinder 7 that discharges the atomized mist is from the body 2. A protruding configuration is desirable.

  The water supply tank 9 is a blow-molded resin container with a handle having a circular opening on the bottom surface. The water supply tank 9 has a flange protruding at the edge of the bottom surface opening. .

  A cap 90 having a valve 99 is screwed into the bottom opening of the water supply tank 9. The valve 99 is mounted on the humidifier body 2 so that the valve member 990 moves upward, so that a moving space is generated, and the tap water falls through the moving space.

  A container-like filter portion 93 filled with ion exchange resin 92 is placed below the water supply tank 9, and is configured to receive tap water dropped from the water supply tank 9 and guide it to the communication path 10. ing.

  At least one air hole 98 is provided in the filter portion (container) 93 that accommodates the ion exchange resin (filter) 92. The air hole 98 is a hole that penetrates from the bottom surface 952 to the top surface 951 of the container 93 that accommodates the ion exchange resin (filter) 92. In FIG. 2, the container 93 of the ion exchange resin (filter) 92 is composed of a bottom surface 952 of the portion filled with the ion exchange resin 92 and an upper surface 951 thereof. Further, the air hole 98 may include a pipe 94 extending on the upper surface of the container 93 that accommodates the filter. The pipe can also be formed as an integral structure without a seam extending from the bottom surface 952, and the structure is shown in the drawing of this example.

  The filter part 93 can be configured by only the filter 92 or can be configured including a container. Further, the air hole 98 has a diameter of about 5 to 20 mm and can have an arbitrary shape such as a circle or a square.

  The air hole 98 or the pipe 94 is provided with a waterproof and moisture permeable material (a material that achieves both waterproof and moisture permeable properties) at the tip portion or in the middle. That is, a material that allows water vapor to pass but does not pass water is arranged so as to block the entire surface of the air hole 98 or the pipe 94.

  In this embodiment, an example in which the water supply unit is provided with a detachable water supply tank 9 has been shown. Therefore, a configuration without the water supply tank 9 can be provided.

  The communication path 10 provided in the humidifying part is a water channel for guiding the water that has passed through the ion exchange resin (filter) 92 to the ultrasonic vibrator 11, and is atomized from the water path by the ultrasonic vibrator. Water is led to the atomization chamber 3 that becomes. The water guided to the atomization section is made into a mist by the ultrasonic vibrator 11 and is humidified indoors from the mist outflow cylinder 7 by the blower fan 6.

  In the above configuration, in the state where humidification is performed, water is continuously supplied to the communication path in the water supply unit. The tap water dropped from the water supply tank is passed through an ion exchange resin (filter) 92, so that mineral components such as magnesium and calcium are efficiently removed and become water suitable for humidification.

  On the other hand, since the air hole 98 provided in the ion exchange resin (filter) 92 or the container 93 is provided with a waterproof moisture-permeable material (a material that achieves both waterproofness and moisture permeability), water continues to flow into the communication path. However, since air flows from the communication path side through the air holes, clogging due to internal pressure does not occur. Even if water enters the air holes, the waterproof and moisture-permeable material serves as a barrier that allows water vapor to pass but prevents water from passing through. All the water reaches only the water filtered through the ion exchange resin. Therefore, the mineral content contained in the tap water to be humidified can be efficiently removed, and a humidifier with improved practicality can be provided.
