Description

  The present invention relates to a humidifier.

  2. Description of the Related Art Conventionally, a humidifier having a reflux passage in a hinge portion is known in order to return condensed water remaining in a steam flow path formed in a lid to an inner container when the lid is opened ( For example, see Patent Document 1).

  However, in the conventional humidifier, when steam is generated, it flows to the reflux passage, and condensation may occur in the reflux passage. Condensed water generated in the reflux passage may cause problems such as scattering outside when the lid is opened.

JP 2008-286483 A

  The present invention prevents the vapor from leaking through the reflux passage for refluxing the dew condensation water generated in the steam passage, and prevents the dew condensation water from being generated in a place other than the reflux passage. It aims at providing the humidifier which can prevent scattering of water.

As a means for solving the above problems, the present invention provides:
A fuselage with an inner container for containing liquid;
A lid that is rotatable to a closed position for closing the opening of the inner container and an open position for opening the inner container;
Heating means for heating the inner container;
A humidifier comprising:
The lid is
A hinge part rotatably supported by the body;
A steam ejection nozzle for ejecting steam generated in the inner container;
A steam channel through which steam ejected from the steam ejection nozzle flows;
A steam hole cover formed with a steam hole covering the steam flow path;
With
The hinge portion is formed with a groove-like reflux passage capable of returning the condensed water remaining in the steam flow path to the inner container when the lid is opened,
The wall surface constituting the steam flow path is formed with a through hole communicating with the reflux passage of the hinge portion,
The opening area of the through hole is set to a minimum size that allows the condensed water remaining in the steam flow path to pass therethrough.

  With this configuration, when dew condensation water remains in the steam flow path, when the lid is rotated to the open position, it is returned from the through hole to the inner container through the return passage of the hinge portion. In addition, when the lid is turned to the closed position and the steam is ejected from the steam ejection nozzle, the through hole is the minimum size that allows the condensed water remaining in the steam flow path to pass through. The amount of steam flowing into the inner container through the reflux passage of the part can be suppressed. Therefore, it is difficult for dew condensation water to be generated in the recirculation passage, and the problem that the dew condensation water generated in the recirculation passage is scattered around when the lid is opened is less likely to occur.

Further, the present invention provides a means for solving the above-described problems,
A fuselage with an inner container for containing liquid;
A lid that is rotatable to a closed position for closing the opening of the inner container and an open position for opening the inner container;
Heating means for heating the inner container;
A humidifier comprising:
The lid is
A hinge part rotatably supported by the body;
A steam ejection nozzle for ejecting steam generated in the inner container;
A steam channel through which steam ejected from the steam ejection nozzle flows;
A steam hole cover formed with a steam hole covering the steam flow path;
With
In a part of the side wall constituting the steam flow path,
In a state where the lid is rotated to the open position, a storage recess for storing the dew condensation water remaining in the steam flow path;
A protruding wall that prevents the condensed water stored in the storage recess from flowing into the steam hole of the steam hole cover;
Is formed.

  With this configuration, even if the cover body is opened to the open position with the dew condensation water remaining in the steam flow path, the dew condensation water is stored by the storage recess and the projecting wall, and the steam hole of the steam hole cover is exposed to the outside. There is no such thing as an outflow.

  The steam hole cover is formed with a stopper wall that is orthogonal or substantially orthogonal to the protruding wall and guides the storage recess on the rotation center side in a state of being attached to the lid so as to cover the steam flow path. Is preferred.

  With this configuration, it is possible to prevent outflow of condensed water stored in the storage recess not only by the protruding wall but also by the stopper wall, so it is possible to sufficiently cope with a large amount of stored condensed water. It becomes.

The hinge portion is formed with a groove-like reflux passage capable of returning the condensed water remaining in the steam flow path to the inner container when the lid is opened,
The wall surface constituting the steam flow path is formed with a through hole communicating with the reflux passage of the hinge part,
It is preferable that the stopper wall includes a notch that allows the condensed water stored in the storage recess to flow into the through hole.

  With this configuration, the dew condensation water stored in the storage recess can be recirculated from the through hole to the inner container through the return passage of the hinge while restricting the position of the cutout.

The steam hole cover forms a grid-shaped steam hole with a plurality of first ribs formed parallel to the rotation center of the lid body and a plurality of second ribs orthogonal to the first ribs. And
The plurality of first ribs preferably include inclined surfaces that overlap with each other in a plan view and have the condensed water flow down to the steam flow path side in a state where the lid is positioned at the open position.

  With this configuration, even when the condensed water remaining in the steam flow path falls into the steam hole by rotating the lid body to the open position, the first ribs are mutually in plan view. Since they are in an overlapping state, condensed water does not flow out to the outside. And since each 1st rib is provided with the inclined surface, the condensed water which fell etc. can be flowed down to the steam flow path side.

  According to the present invention, when the lid is rotated to the open position, the opening area of the through-hole leading to the reflux passage for returning the condensed water remaining in the steam channel to the inner container is defined as the steam channel. Since it has a necessary minimum size through which the dew condensation water remaining inside can pass, the amount of steam flowing to the inner container through the reflux passage of the hinge portion can be suppressed. Therefore, it is difficult for dew condensation water to be generated in other parts via the recirculation passage, and it is possible to prevent the dew condensation water generated in the part other than the recirculation passage from being scattered around when the lid is opened.

  Embodiments according to the present invention will be described below with reference to the accompanying drawings. In the following description, terms indicating specific directions and positions (for example, terms including “up”, “down”, “side”, “end”) are used as necessary. In order to facilitate understanding of the invention with reference to the drawings, the technical scope of the present invention is not limited by the meaning of these terms. Further, the following description is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

  FIG. 1 shows a humidifier according to this embodiment. The humidifier includes a body 1 and a lid 2. In the following description, for the sake of convenience, the side on which the hinge structure that supports the lid 2 so that it can be opened and closed is described as the rear, and the opposite side as the front.

  As shown in FIGS. 2 and 4, the body 1 has a shoulder member 4 attached to the upper opening of the cylindrical exterior body 3, and an inner container 5 is inserted into the center hole from above the shoulder member 4. The bottom side of the inner container 5 is fixed from the bottom member 6 that is hung and disposed in the lower opening of the exterior body 3. A heater 7 is provided on the bottom surface of the inner container 5 so that water stored in the inner container 5 can be boiled to generate steam. An operation display panel 8 is attached to the front surface of the body 1, and various switches and the like for selecting activation and operation modes are provided there.

  The lid 2 is configured such that the inner lid 9 can be attached to and detached from the lower surface, and is attached to the trunk 1 so as to be rotatable about the hinge portion 10.

  As shown in FIG. 5, the hinge portion 10 is formed in a groove shape, and when the lid 2 is opened, the condensed water from the steam flow path 13 to be described later is returned to the inner container 5 in the body 1. Of the passage.

  As shown in FIGS. 2 and 3, an opening / closing lever 11 and a lock knob 12 that keeps the lid 2 closed with respect to the body 1 are provided on the upper surface of the lid 2. . Further, a steam flow path 13 is formed in the rear half of the lid 2 (half on the hinge part side).

  The steam channel 13 is a substantially semicircular recess in a plan view, and a reflux portion 14 is formed at a substantially central portion of the bottom surface. The bottom surface of the steam channel 13 is formed so as to be gradually inclined toward the reflux portion 14 except for the nozzle mounting portion 15. Although not shown in detail for the reflux part 14, the reflux hole is opened and closed by a reflux valve. The recirculation valve closes the recirculation hole when the internal pressure is high, that is, when the internal container 5 is heated and the water stored therein is boiled and the internal pressure rises. On the other hand, when energization to the heater 7 is stopped and the internal pressure decreases, the heater 7 moves downward by its own weight and opens the reflux hole.

  A nozzle mounting portion 15 is formed on one end side of the steam flow path 13 and protrudes upward in a dome shape. A guide portion 16 is formed on the upper surface of the nozzle mounting portion 15, and a vapor jet nozzle 17 made of a flexible tube is positioned there. In the state where the middle part of the steam ejection nozzle 17 is bent and attached to the nozzle mounting part 15, the tip part is directed toward the other end side and gradually approaches the bottom surface side of the steam channel 13.

  A collision wall 18 is formed on the other end side of the steam flow path 13 as a steam dispersion wall for dispersing the steam ejected from the steam ejection nozzle 17. The collision wall 18 is forced to change its flow direction and disperse by the collision of the steam, and lowers its temperature.

  On the side wall on one end side constituting the steam flow path 13, a lattice-like suction port 19 is formed at a position opposite to the ejection direction of the steam ejection nozzle 17. The suction port 19 sucks external air when steam is ejected from the steam ejection nozzle 17 so that the steam can flow smoothly.

  In addition, a storage recess 20 that is recessed outward is formed on the arc-shaped side wall that forms the steam flow path 13. A protruding wall 21 is formed above the storage recess 20 so as to cover it. The storage recess 20 is for storing the condensed water remaining in the steam flow path 13 so as not to flow out of the steam hole 24 when the lid 2 is opened, and the protruding wall 21 increases the storage amount. Playing a role. A through hole 22 is formed near the lower side of the protruding wall 21. The through-hole 22 causes the dew condensation water stored in the storage recess 20 to flow to the hinge portion 10 and return to the inner container 5 side. However, the opening area of the through hole is small so that the amount of steam flowing out in the steam channel 13 can be suppressed as much as possible.

  A vapor hole cover 23 that covers the vapor flow path 13 is detachably attached to the lid 2. The steam hole cover 23 has lattice-shaped steam holes 24 formed by ribs provided in a cross shape. The ribs are in a lattice shape with a first rib 25 extending in the width direction (left-right direction in FIG. 3) and a second rib 26 extending in the vertical direction (up-down direction in FIG. 3).

  The first ribs 25 have a predetermined width dimension in the thickness direction, and are formed so that the portions positioned in the vertical direction overlap each other in a plan view when the lid body 2 is opened (see FIG. 5). Moreover, each first rib 25 is formed so as to be inclined toward the steam flow path 13 at the opening position of the lid 2. Thereby, even if the cover body 2 is opened with the dew condensation water remaining in the steam flow path 13, the first rib 25 prevents the outflow from the cover body 2.

  On the other hand, the second rib 26 is designed to protrude into the steam channel 13 as compared with the first rib 25 in a state where the steam channel 13 is covered with the steam hole cover 23. As a result, the second rib 26 can collide with the vapor spread from the vapor injection nozzle 17 and spread. Therefore, only the steam colliding with the second rib 26 is forcibly changed in direction.

  In the steam hole cover 23, an engagement wall 27 that engages with the opening edge of the steam passage is formed at the lower surface edge of the lid 2. A part of the engaging wall 27 is a stopper wall 28 having a large protruding dimension on the hinge part 10 side, and together with the protruding wall 21 formed in the steam flow path 13, the storage recess 20 is opened when the lid 2 is opened. The condensed water stored in is prevented from flowing out through the steam hole 24. However, a notch 29 is formed in the central portion. The condensed water stored through the notch 29 is returned to the inner container 5 through the hinge 10.

  The steam hole cover 23 is formed with guide ribs 30 that are positioned at a predetermined interval in front of the suction port 19 when mounted on the steam passage. The guide rib 30 is positioned in front of the suction port 19, thereby preventing the steam ejected from the steam ejection nozzle 17 from being accidentally discharged from the suction port 19. As a result, it is possible to appropriately prevent a problem that the steam is discharged from a place other than the steam hole 24.

  Next, the operation of the humidifier configured as described above will be described.

  Energization of the heater 7 is started by a switch operation (not shown), and the water stored in the inner container 5 is heated to generate steam. The generated steam is ejected through the steam ejection nozzle 17 into the steam passage with a slight spread angle. For this reason, a part of the ejected steam collides with each second rib 26 formed on the lid body 2 and is released in a different direction, and a part of the steam is reflected on the bottom surface of the steam passage, or directly. It collides with the collision wall 18. The collision wall 18 is formed so that the steam ejected from the steam ejection nozzle 17 collides almost vertically. For this reason, in the collision wall 18, the reflection direction of the vapor ejected with a slight spread angle is dispersed randomly. Further, the steam reflected by the collision wall 18 collides with the steam toward the collision wall 18. As a result, the temperature of the steam decreases when it is dispersed by the second rib 26 and the collision wall 18. Therefore, the steam temperature is sufficiently lowered when discharged to the surroundings through the steam hole 24, and even if the user accidentally touches the cover body 2 during use, the occurrence of defects such as burns is ensured. Can be prevented.

  In addition, this invention is not limited to the structure described in the said embodiment, A various change is possible.

  For example, in the above-described embodiment, the collision wall 18 in which the steam ejected from the steam ejection nozzle 17 collides substantially vertically is provided. Instead, the bypass wall 31 shown in FIGS. 6 and 7 is provided. It may be. In addition, the same code | symbol is attached | subjected to the part similar to the said embodiment among the structures of the humidifier shown to FIG.6 and FIG.7, and the description is abbreviate | omitted.

  In the steam flow path 13, a detour wall 31 that protrudes in a semicircular cross section is formed on the inner side with respect to the nozzle mounting portion 15 on one end side. Further, the ejection direction of the steam ejection nozzle 17 mounted on the nozzle mounting portion 15 is set to a position that does not directly intersect the bypass wall 31. Further, the lid 2 is formed with a collision rib 32 having a large protruding dimension formed on a part of the second rib 26. A part of the steam ejected from the steam ejection nozzle 17 collides with the collision rib 32 and is dispersed by forcibly changing the flow direction.

  With this configuration, a part of the spread of the steam ejected from the steam ejection nozzle 17 directly collides with the bypass wall and forcibly changes its direction, and flows along the bypass wall 31 in a detour. The steam that bypasses along the bypass wall 31 differs depending on the distance from the surface of the bypass wall 31. Thereby, the vapor is dispersed and flows out from a wide range of the vapor holes 24 of the lid 2 to the outside. As a result, the temperature of the steam flowing out to the outside is sufficiently lowered.
