Description

  The present invention relates to a humidifier that humidifies indoor air, and more particularly, to a humidifier that humidifies air through a humidifying filter containing moisture.

  In general, a humidifier has an air filter attached to the front surface of a main body, and an air passage in which a blower is arranged in the path is formed inside the main body. The ventilation path extends from the opening in the front of the main body to the outlet at the top of the main body, and a humidifying filter containing moisture is disposed upstream of the blower downstream of the air filter. In accordance with the rotation of the blower, such a humidifier sucks indoor air, which is outside air, into the air passage through the air filter, humidifies the sucked air through the humidifying filter, and blows it out to the outside room from the outlet. At that time, harmful substances contained in the air are removed by the air filter, thereby purifying the air. The air purified through the air filter takes in moisture when passing through the humidifying filter, and is humidified thereby. Thus, when the indoor air is particularly abnormally dried, the air can be humidified and adjusted to a comfortable state.

In such a humidifier, a tray is stored on the bottom surface of the main body from one side of the main body, and water is stored in the tray. The lower part of the humidifying filter is immersed in the water in the tray, and the water is sucked up to contain moisture. A water supply tank that stores water is connected to the end of the tray from above, and water is supplied from the water supply tank in a timely manner. (For example, refer to Patent Document 1).
Utility Model Registration No. 3115357

  By the way, in the conventional general humidifier described above, the tray can be freely removed from one side of the main body by sliding on the bottom surface for maintenance such as cleaning of the tray itself or replacement of the humidifying filter. ing. On the contrary, the tray is inserted and stored from one side of the main body to the proper position by sliding movement, and the humidification operation is performed.

  However, in such a humidifier, the tray may be shifted from the normal position because the tray is not inserted to the normal position, or an unexpected impact is applied when the water supply tank is attached or detached. When the tray is shifted from the normal position, an unplanned gap is created between the main body and the tray. When the humidification operation is performed in this state, external air is sucked into the downstream side of the humidification filter from an unplanned gap between the main body and the tray, and as a result, the humidification efficiency is lowered.

  Then, this invention is made | formed in view of said problem, and it aims at providing the humidifier which can perform an efficient humidification operation stably.

  In order to achieve the above object, a humidifier according to the present invention is a humidifier that sucks and humidifies external air according to rotation of a blower in an air passage, and blows out the humidified air to the outside. A tank, a tray that stores water from the water supply tank, and a humidifying filter that is disposed in the aeration path and has a lower part immersed in the water stored in the tray. The tray includes a humidifier together with the humidifying filter. From one side of the main body, the water supply tank is inserted and stored on the bottom surface of the main body, and the water supply tank is inserted into the end portion of the tray from above. The end of the tray is provided with a shaft member that extends in the vertical direction while being biased upward, and is pushed downward by the attached water tank and protrudes from the bottom of the tray. A receiving hole is formed in the bottom surface of the main body to receive the lower end portion of the shaft member protruding from the bottom of the tray in a state where the tray is inserted and stored to a proper position.

  With such a configuration, the sliding movement of the tray is restricted by the engagement between the shaft member from the tray and the receiving hole of the main body when the water supply tank is mounted, and the tray does not deviate from the normal position.

  According to the humidifier of the present invention, an efficient humidification operation can be stably performed only by attaching a water supply tank.

  Hereinafter, an embodiment of a humidifier according to the present invention will be described in detail with reference to the drawings. Here, the humidifier will be described as an example of a humidifier that can also be used as an air purifier depending on selection and that also has an ion release function.

It is the top view seen from one side. 8 and 9 are cross-sectional views in front view showing an enlarged connection portion between the water supply tank and the tray in the humidifier. FIG. 8 shows a state in which the water supply tank is mounted, and FIG. 9 shows the water supply tank. It shows the state where is removed.

  The humidifier 1 is placed on a floor or hung on a wall at a proper place in the room during operation. In general, the humidifier body 2 and the front panel 3 constitute an outer shell. The main body 2 has an outer shape as a generally flat box standing vertically as a whole, and an air filter housing portion that is greatly recessed in a rectangular parallelepiped shape is formed on the front surface thereof. In this air filter housing portion, the deodorizing filter 4 and the dust collecting filter 5 are housed in an overlapped manner as an air filter in order from the opening on the front side.

  The deodorizing filter 4 has a non-woven fabric made of polyester attached to a rectangular frame, activated carbon is uniformly distributed on the non-woven fabric, and a non-woven fabric made of polyester is further covered thereon. The deodorizing filter 4 serves to adsorb acetaldehyde, ammonia, acetic acid and the like which are odor components in the air. On the other hand, the dust collection filter 5 is a so-called HEPA (High Efficiency Particulate Air) filter, which is made of a polyester / vinylon non-woven fabric aggregate and a melt blown non-woven fabric that has been processed by electrolithography. An antibacterial sheet made of a non-woven fabric processed with hydroxyapatite is stacked on the lower surface and thermocompression bonded, and a frame made of a non-woven fabric with hot melt is welded. The dust collection filter 5 plays a role of collecting fine dust.

  The deodorizing filter 4 and the dust collection filter 5 housed in the air filter housing part are prevented from falling out of the air filter housing part by the filter pressing frame 6 attached to the opening of the air filter housing part. The filter holding frame 6 has a substantially rectangular shape, and a large number of ventilation holes are formed in a matrix.

  The front panel 3 is attached with a predetermined gap to the front of the main body 2 in which the deodorizing filter 4 and the dust collecting filter 5 are housed and the filter holding frame 6 is mounted, and the deodorizing filter 4 and the dust collecting filter 5 are attached to each other. Including the filter presser frame 6 completely. Here, the front panel 3 is supported by hooking a hook (not shown) bent toward the main body 2 from the upper portion of the main body 2, and the lower portions on both the left and right sides are fixed by the locking portions 7. The The gap between the back surface of the front panel 3 and the front surface of the main body 2 is open to the outside on the left and right sides, and external air is introduced from here.

  In the main body 2, the blower 8 is disposed behind the air filter housing portion with the partition wall 21 interposed therebetween. The blower 8 here includes a fan motor 9 and a fan 10, the front side thereof is isolated by the partition wall 21, the lower side thereof is isolated by the partition wall 22, and the back side thereof is isolated by the partition wall 23. Among these, the fan motor 9 is fixed to the partition 21 on the front side, and a large number of ventilation holes communicating with the blower 8 are formed in the partition 23 on the back side. Although the turbo fan is employ | adopted as the fan 10, the kind of fan is not limited to this. A propeller fan or a cross flow fan can be used. In the case of a turbo fan, a device is devised to increase the thickness compared to the fan diameter and reduce the noise level. As the fan motor 9, it is preferable to employ a direct current motor in consideration of ease of control.

  Further, the main body 2 is formed with a first air outlet 11 that opens upward and a second air outlet 12 that opens upward in the upper portion corresponding to the upper side of the blower 8, and the power on / off An operation / display unit 13 is provided that includes operation buttons for turning off and setting operation and a display lamp for displaying the operation state.

  In accordance with the driving of the blower 8, that is, the rotation of the fan 10 by the fan motor 9, indoor air that is external air is introduced from the gap between the front panel 3 and the main body 2. The introduced air reaches the air filter through the vent of the filter holding frame 6 and is purified by the deodorizing filter 4 and the dust collecting filter 5 into air having no odor or dust. The purified air reaches the back wall 25 of the main body 2 through the opening 24 formed in the lower part of the partition wall 21 at the back of the air filter housing portion, and rises between the partition wall 23 and the back wall 25, and then the partition wall 23. The air is sucked into the center of the fan 10 from the air vent. The air sucked into the center of the fan 10 passes between the fan blades, is discharged from the outer periphery of the fan 10, is guided upward, and enters the outside room from the first air outlet 11 and the second air outlet 12. Blown out. Such an air flow corresponds to the air passage.

  Here, an air passage extending from the opening 24 formed in the partition wall 21 at the back of the air filter housing portion to the back along the partition wall 22 is vertically divided by the partition wall 27, and the first air passage 31 in order from the bottom, A second ventilation path 32 is formed. That is, the air passage from the air filter to the blower 8 once branches into the first air passage 31 and the second air passage 32 and then merges with each other.

  The humidification filter 14 is arranged in the first ventilation path 31 so as to block almost the entire cross-sectional area. Specifically, a tray 15 that is detachable from one side (left side in the figure) is stored in the lower part of the main body 2, and water is stored in the tray 15 at a certain water level. The humidifying filter 14 is made of a water-absorbing material folded in a zigzag, and is inserted into the tray 15 so that the lower part is immersed in water, and the water is sucked into a state containing moisture. A water supply tank 16 storing water is connected to the end of the tray 15 from above, and water is supplied from the water supply tank 16 in a timely manner. The water supply tank 16 is detachably attached to the side portion (left side portion in the figure) of the main body 2 on the side where the tray 15 is attached and detached.

  Here, the structure of the water supply tank 16 in this embodiment and the structure of the connecting portion between the water supply tank 16 and the tray 15 are as follows in detail. As shown in FIGS. 1 and 4 to 7, the water supply tank 16 is mainly composed of a tank body 60, a cap 63, and a cover 66. The tank main body 60 has a hollow shape such that a generally flat box as a whole stands vertically, and plays a role of substantially storing water.

  A water injection port 60a protrudes from the lower surface of the tank main body 60, and water is poured from the water supply or the like into the tank main body 60 through the water injection port 60a. A cap 63 is screwed into the water inlet 60a. As shown in FIGS. 8 and 9, the cap 63 incorporates a valve body 64. When the water supply tank 16 is attached to the main body 2 and connected to the tray 15, the valve body 64 is pushed up and opened by a convex portion 15 a protruding upward from the tray 15, and the water supply tank 16 is removed from the main body 2. When this occurs, it is disengaged from the convex portion 15a of the tray 15 and lowered by the restoring force of the compression coil spring 65 to close. And the water in the tank main body 60 is supplied to the tray 15 through the water inlet 60a and the opened valve body 64 (refer FIG. 8).

  A cover 66 covering the upper surface of the tank body 60 is fixed with screws 67. The cover 66 is provided with a handle 68 that is open to one side of the main body 2 (corresponding to the front of the four side surfaces of the tank main body 60) on which the water supply tank 16 is attached and detached. The handle 68 is supported so as to be rotatable up and down. The tank body 60 is formed with a recess 60b so that a hand can be inserted into the handle 68 from below.

  The handle 68 is formed with a protrusion 68a protruding upward at the end opposite to the side into which the hand is inserted, and the protrusion 68a engages with the hole on the main body 2 side, so that the water supply tank 16 is connected to the main body 2 2 is locked in a state of being attached. When the handle 68 is pulled up, the handle 68 is rotated and the projection 68a is lowered, whereby the projection 68a is removed from the hole on the main body 2 side and the lock is released. If the handle 68 is held and pulled forward, the water supply tank 16 falls to the front with the cap 63 as a fulcrum, and the water supply tank 16 can be lifted obliquely upward and removed from the main body 2 (see FIG. 9).

  In particular, in the present embodiment, the tray 15 can be detached from one side of the main body 2 by sliding movement on the bottom surface 28 of the main body 2, and is inserted into the back so that the tray 15 is stored in a normal position. Become. The water supply tank 16 can be attached to and detached from the end of the tray 15 housed in the main body 2 by moving up and down with the cap 63 (water inlet 60a) down, and is inserted and attached from above. Prior to the installation of the water supply tank 16, the main device 2 and the tray 15 are devised as follows.

  As shown in FIGS. 8 and 9, the tray 15 is provided with a shaft member 18 extending in the vertical direction at an end corresponding to a position where the water supply tank 16 is mounted. The shaft member 18 is supported while being vertically guided in the vicinity of both the upper end 18 a and the lower end 18 b, and is urged upward by a compression coil spring 19. In a state where no external force is acting, the upper end portion 18a protrudes from the upper surface of the tray 15, and the lower end portion 18b is retracted from the bottom of the tray 15 (see FIG. 9).

  In addition, a receiving hole 28 a having a diameter slightly larger than the diameter of the shaft member 18 is formed in the bottom surface 28 of the main body 2 immediately below the shaft member 18 in the tray 15 housed in a regular position. When the water supply tank 16 is mounted with the tray 15 stored in the proper position, the lower surface of the tank body 60 abuts on the upper end portion 18a of the shaft member 18, and the shaft member 18 is pushed down as it is. This time, the lower end portion 18 b of the shaft member 18 protrudes from the bottom of the tray 15. The protruding lower end 18b of the shaft member 18 is inserted into the receiving hole 28a of the main body 2 and engaged (see FIG. 8). Due to the engagement of the shaft member 18 from the tray 15 and the receiving hole 28a of the main body 2 when the water supply tank 16 is mounted, the sliding movement of the tray 15 is restricted and does not deviate from the normal position. Therefore, efficient humidification operation can be stably performed only by installing the water supply tank 16.

  When the water supply tank 16 is removed from here, the external force to the shaft member 18 is lost, so that the shaft member 18 protrudes from the upper end portion 18a and retracts the lower end portion 18b by the restoring force of the compression coil spring 19. In this state, the engagement between the shaft member 18 from the tray 15 and the receiving hole 28a of the main body 2 is released, and the sliding movement of the tray 15 is allowed. Therefore, the tray 15 can be freely removed, and there is no problem in maintenance such as cleaning and replacement of the humidifying filter 14.

  On the other hand, the second ventilation path 32 is provided with a movable plate 35 that opens and closes the second ventilation path 32. Here, the movable plate 35 is a curved plate that is supported by a support shaft 36 that is disposed slightly above the second ventilation path 32 along the left-right direction, and that is curved in an arc shape around the support shaft 36. The support shaft 36 is turned around a fulcrum. The rotation of the movable plate 35 is driven by a digital control motor such as a stepping motor. Accordingly, the rotational position of the movable plate 35 is always recognized.

  As shown in FIG. 2, the movable plate 35 has a limit position of rotation, and a projection 37 protruding outward from the inner edge of the movable plate 35 abuts the end surface of the inner wall of the partition wall 27. As a result, the posture rotated most forward of the movable plate 35 is defined. In this posture, the movable plate 35 closes the second air passage 32. When the blower 8 is driven in this state, the air purified through the air filter flows into the first air passage 31 because the second air passage 32 is closed by the movable plate 35, and the humidifying filter 14 is reached. When the air passes through the humidifying filter 14, the air takes in moisture from the humidifying filter 14 and is then humidified. Thereafter, the air rises between the partition wall 23 and the back wall 25, and finally the first outlet 11 and the second outlet The air is blown out from the air outlet 12. Then, at this time, not only air purification but also humidification is performed efficiently.

  On the contrary, as shown in FIG. 3, the protrusion 37 of the movable plate 35 abuts against the protruding piece 26 protruding from the back wall 25, thereby defining the posture of the movable plate 35 that is rotated to the innermost side. In this posture, the movable plate 35 opens the second air passage 32 and closes the junction from the first air passage 31. When the air blower 8 is driven in this state, the air purified through the air filter is eventually passed through the first air passage 31 because the junction of the first air passage 31 is closed by the movable plate 35. Does not flow in, and the second air passage 32 is open, and therefore flows into the second air passage 32. The air is guided along the movable plate 35, then rises between the partition wall 23 and the back wall 25, and finally blown out from the first blowout port 11 and the second blowout port 12. . Then, at this time, humidification is hardly performed and air purification is mainly performed.

  Therefore, in the humidifier 1 of the present embodiment, the efficiency of humidification can be adjusted by opening and closing the movable plate 35 as necessary with respect to the second air passage 32. As a result, the purification of the air is performed. And humidification can be done efficiently and effectively.

  In the present embodiment, an ion generator 17 that generates positive and negative ions simultaneously or individually is disposed between the second outlet 12 and the blower 8. When the ion generator 17 is driven, ions are released from the ion generator 17 into the air mainly directed from the fan 10 to the second outlet 12, and purified air and further humidified air absorb ions. Including, it is mainly blown out into the room from the second outlet 12.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the present invention can be applied to a general humidifier that does not have the partition plate 27 and the movable plate 35 and has one air passage from the air filter to the blower 8 without branching.

  In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
