  According to one embodiment of the present application, as shown in FIG. 2 to FIG.

  The humidification tank 100 is a container for storing a humidifying agent. The humidifier may include clean water, or a specific air cleaner or deodorant may be added as determined by the environment in which the humidifier is used. The humidifying tank 100 may be a container having an upper opening. In one embodiment, the humidification tank 100 is a parallelepiped having an upper opening, but the present application is not limited thereto, and the humidification tank 100 may have any other suitable shape such as, for example, a cylinder or a polygonal column. You may employ | adopt the container which has. The humidification tank 100 may be made from a metal or plastic material. In this embodiment, the humidification tank 100 is injection-molded with a plastic material.

  The humidifying filter screen 200 is typically made from a hydrophilic foam that lasts in the humidifying tank 100, and the lower edge 201 of the humidifying filter screen 200 is in physical contact with the humidifying agent to suck up the humidifying agent in the humidifying tank 100. doing. When an airflow (hereinafter also referred to as “wind”) passes through the humidifying filter screen 200, the airflow carries the humidifier sucked up from the humidifying tank 100 by the humidifying filter screen 200, thereby humidifying the air or cleaning the air. To play a role.

  The tray 300 has a shape corresponding to the cross section of the humidifying tank 100. That is, if the humidification tank has a rectangular, circular, or polygonal cross section, the tray 300 also has a corresponding rectangular, circular, or polygonal cross section. The tray 300 is disposed in the humidification tank 100 so as to be movable in the vertical direction. That is, the cross-sectional size of the tray 300 is smaller than the cross-sectional size of the humidifying tank 100. The tray 300 can support the humidifying filter screen 200 and maintain physical contact with the humidifying agent at the lower edge 201 of the humidifying filter screen 200. A foam material 310 is provided on the lower side of the tray 300, so that the buoyancy generated by the tray 300 and the foam material 310 in the humidifying agent is balanced with the total weight of the humidified filter screen 200, the tray 300, and the foam material 310. The humidifying filter screen 200 and the tray 300 can be maintained in a floating state on the liquid surface of the humidifying agent.

  If the cross section of the tray 300 is circular, elliptical, or polygonal, the foam 310 may be disposed along the peripheral edge on the lower side of the tray 300, thereby causing the peripheral edge of the tray 300 to be disposed. The buoyancy generated by the adjacent foam material 310 is ensured. Therefore, since all the buoyancy points are adjacent to the peripheral edge of the tray 300, the tray 300 can reliably move in the vertical direction without tilting. When the foam material collects near the center of gravity of the tray 300, the tray can float on the surface of the humidifying agent according to the change in the liquid level, but the tray becomes unstable, that is, the tray moves up and down. It can be inferred that the tray can tilt during movement. This basic principle can also be applied in other embodiments of the present application.

  When the tray 300 has a rectangular shape, the foam material 310 may be disposed symmetrically about the center of gravity of the tray 300 and the humidifying filter screen 200. For example, two foam materials 310 may be disposed at diagonal corners on the lower side of the tray 300, and four foam materials 310 may be disposed at four corners on the side surface of the tray 300.

  According to one embodiment of the present application, the tray 300 may further include a plurality of recesses 320 on the lower side of the tray 300, and the recesses 320 are also symmetrical about the center of gravity of the humidifying filter screen 200 and the tray 300. Arranged. The recess 320 is disposed on the lower side of the tray 300. When the concave portion 320 is in contact with the humidifying agent in the humidifying tank 100, a void is generated in the concave portion 320. The void generated in the recess 320 increases the buoyancy of the tray 300 in the humidifier. For this reason, the volume and number of the recesses 320 need to be determined according to the magnitude of the buoyancy generated by the tray 300 in the humidifying agent.

  One skilled in the art can design the volume and number of recesses 320 considering the configuration of the foam 310 in addition to the total buoyancy required for the tray 300. This is a balance calculation problem well known to those skilled in the art, between the weight supported by the tray 300 and the buoyancy generated by the tray 300, foam 310, and recess 320 in the humidifier. Do not repeat in

  According to one embodiment of the present application, the humidifier 10 may further include a filter screen frame 210, the end of the humidified filter screen being surrounded by the filter screen frame 210 and mechanically attached to the filter screen frame 210. Are combined. In this embodiment, the humidified filter screen 200 has a rectangular shape and the filter screen frame 210 has a rectangular shape to facilitate mechanical coupling of the humidified filter screen 200 with the filter screen frame 210. It may have a rectangular shape corresponding to. However, the present application is not limited to this, and the humidifying filter screen 200 and the filter screen frame 210 may have any suitable corresponding shape that can be freely selected by those skilled in the art according to actual design conditions. Good.

  When both of the humidifying filter screen 200 and the filter screen frame 210 have a rectangular shape, the humidifying device 10 may further include a windshield mechanism 211 disposed above the filter screen frame 210. This is because, for example, in an example of a humidifier, the liquid level of the humidifier gradually decreases during operation of the humidifier, and the tray 300 is gradually lowered together with the humidifying filter screen 200. Due to this lowering of the upper edge portion 202 of the humidifying filter screen 200, the gap between the upper edge portion 202 and the humidifier body gradually becomes wider, and some airflow passes through the gap without passing through the humidifying filter screen 200. Become. Therefore, the problem that the airflow escapes from above the humidifying filter screen 200 while the humidifying filter screen descends with the liquid level of the humidifying agent must be addressed. In order to achieve this object, according to an embodiment of the present application, the windshield mechanism is disposed at the upper edge portion of the static windshield panel 211a disposed above the filter screen frame 210 and the filter screen frame 210. A dynamic windshield panel 211b. The dynamic windshield panel may maintain overlap and fit with the static windshield panel by moving vertically with the filter screen frame 210. However, the present application is not limited to this, and the windshield mechanism on the filter screen frame 210 may be any other suitable means. According to another embodiment (not shown) of the present application, the windshield effect that does not affect the vertical movement of the humidifying filter screen 200 is between the upper edge of the filter screen frame 210 and the humidifier body. It can also be realized by a flexible windshield arranged.

Although not shown, the guide mechanism may include, for example, a guide rail disposed on the inner side wall of the humidifying tank 100 and a guide slot disposed on the outer edge of the tray 300. A technical effect similar to the technical effect can be realized. Also, as is well known to those skilled in the art, the guide mechanism may be arranged symmetrically with respect to the cross section of the humidifying tank 100 and tray 300 (eg, a set of symmetrically arranged guide mechanisms, or two A set of symmetrically arranged guide mechanisms). Also, the guide mechanism is not limited to the pattern of guide slots and guide rails, and the guide mechanism may include any other pattern known to those skilled in the art (e.g., sliding and groove engagement) The person may choose appropriately according to the specific structure.

  According to one embodiment of the present application, the foam material 310 is a hydrophobic foam material and may be any foam material known to those skilled in the art as long as it is a suitable foam material. This is because hydrophobicity and lightness can cause buoyancy in the humidifier. However, since different foams generate different buoyancy in the humidifier, the designer may select the type and amount of foam according to actual needs.
