Description

  The present invention relates to a humidifying device that gives humidity to air by passing air through a vaporization filter containing water, and more particularly, to a structure that ventilates the vaporization filter.

  In a conventional vaporizing humidifier, an air suction port and an air outlet are provided, and a housing having an air passage that connects the air inlet and the air outlet is provided inside the air passage. A blower is arranged to suck in air from the air and blow out the sucked air through the air passage from the outlet.

  In the air passage between the blower and the suction port, a water supply tray for storing water supplied from the water supply tank and an upper side of the water supply tray are disposed, and the water stored in the water supply tray is absorbed to be wet. A vaporizing filter that provides humidity to the air passing in the state is arranged.

  During the humidifying operation, the humidifier is configured to pass the air sucked from the suction port through a moistened vaporization filter by the rotation of the blower, so that the sucked air is humidified and blown out from the outlet.

A rotation shaft at the center is supported.

  However, in Patent Document 1, since the frame body holding portion is erected from the water supply tray and is disposed so as to face the vaporization filter, the frame body holding portion hinders the ventilation of air to the vaporization filter. . Therefore, air does not pass through a part of the vaporization filter facing the frame body holding portion of the entire vaporization filter, and the vaporization filter cannot be effectively used.

  In Patent Document 1, when it is considered that the wind speed of the air passing through the vaporizing filter and the area of the vaporizing filter are unchanged, the vaporizing filter has a non-passing surface through which air does not pass. Only the use area of the vaporization filter is substantially reduced. For this reason, there has been a problem that the amount of passing air passing through the vaporization filter represented by the product of the wind speed and the area is substantially reduced, and a sufficient amount of humidification cannot be ensured.

The heater deodorizing unit 54 includes a heater and a deodorizing filter, and the deodorizing filter is heated by the heater to decompose and remove malodorous components such as oily odor and tobacco or pet odor adhering to the deodorizing filter. .

  The vaporization filter 14 is a pleated filter having air permeability and water absorption, and is a filter in which polyester and rayon are blended at a ratio of 50:50. The vaporization filter 14 absorbs water and wets the air while the air passes, so that the water vaporizes and gives humidity to the air. In addition, the kind of material of the vaporization filter 14 and the ratio of mixing | blending can be suitably selected, without limiting to this.

  The blower 12 includes a fan motor 12a and a fan 12b driven by the fan motor 12a. By rotating the fan 12b, the blower 12 sucks air from the suction port 26 (white arrow A). Is blown out from the outlet 28 through the air passage (open arrows E and F).

  The ozone generation unit 16 is provided in an upper portion of an air passage that extends upward from the downstream side of the blower 12, and from the upstream side to the downstream side in the ozone generation unit 16, the inlet 161, the ozone generation unit 16 a, and the ozone decomposition catalyst. 58, the low-concentration ozone outlet 162 is arranged in order.

  The ozone generator 16a is a UV lamp such as a mercury lamp, and generates ozone by the ultraviolet light of the UV lamp. When the ozone generated in the ozone generation unit 16 is blown out from the low-concentration ozone outlet 162, the ozone decomposition catalyst 58 generates ozone by the action of a metal catalyst such as titanium oxide in order to bring the ozone concentration into an appropriate range.

Next, while the dust-removed and deodorized air passes through the vaporization filter 14, water is vaporized from the wet vaporization filter 14 and is humidified.

  The humidified air is sucked into the fan 12b of the blower 12 and sent out to the air passage extending upward from the downstream side of the fan 12b (white arrow B). Next, the air sent out to the air passage is blown out from the blowout port 28 with the louver 30 opened (open arrow E).

  The negative ions generated by the negative ion generator 46 are released by riding on the air (white arrow E) blown from the outlet 28. The released negative ions adhere to microorganisms such as molds and viruses floating in the air outside the humidifier and inactivate them.

  Part of the humidified air is taken into the ozone generation unit 16 from the suction port 161 (open arrow C), and ozone is generated by the ozone generation unit 16a. Excess ozone is decomposed in the generated ozone by the ozone decomposition catalyst 58. Ozone that has been decomposed into excess ozone and having a low concentration (0.02 ppm or less) passes through the low-concentration ozone outlet 162 (open arrow F) and is blown out from the outlet 28.

  On the other hand, a part of the ozone generated in the ozone generation unit 16a has a negative pressure near the wind surface of the vaporization filter 14 and a positive pressure near the ozone generation unit 16. To the wind surface of the vaporization filter 14 from the spray port 18a (arrow D).

  The ozone sprayed on the vaporization filter 14 sterilizes and deodorizes the vaporization filter 14 while passing through the vaporization filter 14 together with the air sucked from the suction port 26. Thereby, the vaporization filter 14 is always kept clean.

  Next, the configuration around the vaporization filter 14 will be described.

The space between the arm portions 15d is open, and the vaporization filter 14 is exposed so that air can pass therethrough.

  The gear cover 15g includes a ring-shaped frame 15h, a rotating shaft 15i, and an arm portion 15j. A driven gear 15k integrally formed in the circumferential direction is provided on the outer peripheral side of the annular frame 15h, and an accommodating portion 15m for accommodating the vaporization filter 14 is provided on the inner peripheral side of the annular frame 15h. The rotary shaft 15i is formed in a cylindrical shape in the air passage direction (white arrow A), and is connected to the ring-shaped frame 15h via a plurality of arm portions 15j extending radially in a direction orthogonal to the air passage direction. ing. The space between the arm portions 15j is open, and the vaporization filter 14 is exposed so that air can pass therethrough.

  In the water turbine unit 15, the driven gear 15k is meshed with a drive gear 22a connected to the output shaft of the filter rotation motor 22, and by driving the filter rotation motor 22 such as a synchronous motor, the rotation shaft 15c and the rotation shaft 15i. It can be rotated at a constant speed together with the vaporization filter 14 in a direction (arrow G) orthogonal to.

  Further, in the air passage, a water supply unit 24 for supplying water for supplying water to the vaporization filter 14 is provided on the lower side of the water turbine unit 15 (vaporization filter 14). The water supply unit 24 includes a water supply tray 24a, a water supply tank holding portion 24b, a partition plate 24c, and a pair of water turbine unit holding portions 24d.

  The water supply tray 24a stores water supplied from a water supply tank (not shown) and communicates with the water supply tank holding part 24b through the through hole 24b1. The water supply tank holding unit 24b is a holding unit that holds the water supply tank, and supplies water from the water supply tank to the water supply tray 24a through the through hole 24b1 when the water in the water supply tray 24a falls below a certain level. The partition plate 24c partitions the water wheel unit 15 and the water supply tank.

  The pair of water turbine unit holding portions 24d are respectively erected from the center of both side surfaces in the longitudinal direction of the water supply tray 24a, and hold the water wheel unit 15 rotatably. The upper ends of the pair of water turbine unit holding portions 24d are respectively provided with bearing portions 24h, and the rotating shaft 15c and the rotating shaft 15h of the water turbine unit 15 are pivotally supported by these bearing portions 24h.

  Thereby, a pair of water turbine unit holding | maintenance part 24d is arrange | positioned so that it may each oppose to the wind upper surface and the wind lower surface of the vaporization filter 14 orthogonal to the passage direction (white arrow A). It should be noted that the pair of water turbine unit holding portions 24d are at a height that does not directly absorb water by the vaporization filter 14 in a state where water of a certain water level is stored in the water supply tray 24a, and at a height that allows water to be pumped by the water pump pocket 15e. It is erected.

  Each of the pair of water turbine unit holding portions 24d includes a ventilation hole 24e that allows a part of the air flowing through the air passage to pass therethrough. These ventilation holes 24e are composed of a plurality of substantially rectangular holes divided by a vertical beam 24f and a horizontal beam 24g. Thus, even if the water turbine unit holding portion 24d is provided with the ventilation holes 24e, the strength of the water wheel unit holding portion 24d can be secured because the vertical rail 24f is connected to the horizontal rail 24g. . The water turbine unit holding portion 24d is integrally formed with the water supply tray 24a in this embodiment, but may be a separate member from the water supply tray 24a.

Since a part of the air passes, the vaporization filter 14 can be used effectively.

  More specifically, the wind turbine unit holding part 24d on the windward side does not hinder the ventilation of the vaporization filter 14, and the use area of the vaporization filter 14 that contributes to humidification of the air increases. Therefore, the amount of air passing through the vaporization filter 14 is reduced. The amount of humidification in the vaporization filter 14 can be sufficiently ensured.

  Further, since the leeward water turbine unit holding part 24d does not hinder the ventilation of the air humidified by the vaporization filter 14, it is possible to form a smoother flow of air and blow out the humidified air from the outlet 28. it can.

  Next, another embodiment of the pair of water turbine unit holding portions 24d will be described with reference to FIG. In addition, since the structure of the bearing part 24h with which the upper end of a pair of water turbine unit holding | maintenance part 24d is different from the humidification apparatus by this embodiment demonstrated so far, description is abbreviate | omitted about another structure.

  As shown in FIG. 12, the wind turbine unit holding portion 24d is provided with a through hole 24i that passes through the center of the bearing portion 24h and allows a part of the air flowing through the air passage to pass therethrough. Similarly, the leeward water turbine unit holding portion 24d (not shown) is provided with a through hole 24i that passes through the center of the bearing portion 24h and allows a part of the air flowing through the air passage to pass therethrough.

  Part of the dedusted and deodorized air passes through the through hole 24i provided in the wind turbine unit holding part 24d on the windward side, and then passes through the vaporization filter 14 via the cylindrical rotating shaft 15c and is humidified. The air passes through the through hole 24i provided in the leeward water turbine unit holding part 24d via the cylindrical rotating shaft 15i. As a result, in the humidifier according to the present embodiment, the use area of the vaporization filter 14 that contributes to the humidification of air can be further increased, and the amount of air passing through the vaporization filter 14 can be further increased.
