Description

  The present invention relates to a humidifier for keeping a room at a desired humidity and moisturizing the skin and throat of a human body, and more specifically, prevents dew condensation water generated in a steam passage from entering a blower pipe. Technology.

  Conventionally, it is generated in a water supply tank that stores water, a steam generation part that heats water supplied from this water supply tank to generate steam, a steam generation discharge port that discharges steam to the outside, and a steam generation part There is provided a humidifier including a steam passage for sending the steam to the steam outlet. In the humidifier, if the generated high-temperature steam is discharged as it is, there is a risk of causing burns and other hazards to the user. For example, a structure in which the air taken in from the outside through the filter is sent into the steam passage through the blower pipe and mixed with the steam to reduce the temperature by the blowing pressure of the blowing unit, which is a fan motor, for example. (See Patent Document 1).

However, in the structure in which air is sent from the blower pipe into the steam passage in this way, the blower opening opened at the end face of the blower pipe and the condensed water generated around the blower pipe pass through the blower pipe to the blower unit. In other words, there were problems such as failure due to adhesion of water and a reduction in blowing capacity.

  This invention is invented in view of the said problem, Comprising: It aims at providing the humidifier which can prevent the invasion of the dew condensation water in a ventilation pipe reliably.

The humidifier according to the present invention in order to solve the above problems, a steam generator for generating steam by heating, the steam discharge port for discharging the steam to the outside, the steam generated in the steam generating portion and the vapor ejection a steam passage of the steam pipe for feeding to the outlet, a blower providing air pressure sent to the air taken in from the outside, the air blown from the blower unit and an air pipe for feeding into said steam passage, said blast pipe that crossed in said steam path, with further penetrate the steam pipe, its upper end opening is communicatively connected to Nanomisuto generator was characterized by the air blowing port was opened in the peripheral wall of the air pipe in the intersection And In this way, the air that is blown from the blower is fed into the steam passage through the blower opening, it is possible to reduce the temperature of the steam discharged to the outside from the steam discharge port. And since the ventilation opening is formed in the side wall of the ventilation pipe, it is difficult for the condensed water generated in the steam passage to penetrate into the ventilation pipe through the ventilation opening, and the condensed water passes through the ventilation pipe. It is prevented that it reaches a ventilation part and causes the failure and the fall of ventilation capability. Moreover, the air discharged into the nano mist generating part is mixed with the nano mist and discharged outside from the nano mist discharge port.

  It is preferable that the air blowing port 27 is formed in a mesh shape. With such a net-like air outlet 27, the dew condensation water is more difficult to pass through, and the dew condensation water can be more reliably prevented from entering the air blow pipe 26 through the air outlet 27.

  The opening direction of the air blowing port 27 is preferably a direction that does not face the direction in which steam is sent out in the steam passage 28. By doing in this way, it can prevent more reliably that dew condensation water permeates in the ventilation pipe 26 via the ventilation port 27. FIG.

  Further, it is also preferable to provide a predetermined distance D for preventing intrusion of condensed water into the blower pipe 26 between the lower end of the blower port 27 and the inner peripheral wall of the steam passage 28 at the intersection. By setting such a predetermined distance D, even if the dew condensation water generated on the inner peripheral wall of the steam passage 28 forms a puddle, it can enter the blower pipe 26 through the blower port 27. It is to be prevented.

In the humidifier of the present invention, the air discharged into the steam pipe is mixed with the steam in the middle of being sent to the steam outlet in the steam passage which is the internal space of the steam pipe. While reducing the temperature, the condensed water generated in the steam passage is prevented from entering the blower pipe through the blower port, and the air discharged into the nanomist generating part is mixed with the nanomist and is externally supplied from the nanomist discharge port. This produces the effect of being discharged into the water.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. 2 and 3 show the appearance of an example of the humidifier according to the embodiment of the present invention, and FIG. 1 shows a cross section of the humidifier of this example. An operation unit 1 and a transparent or translucent water level panel 2 are provided on the front surface of the humidifier housing 5, a retractable handle 3 is provided on both upper side surfaces of the humidifier housing 5, and air purification is provided on the back surface. A filter case 4 having a built-in filter (not shown) is provided. The operation unit 1 includes a power switch 7 for turning on / off the power, a humidifying switch 8 for turning on / off the humidifier, an off timer 9 for setting a humidifying operation time, and a water amount in a water supply tank 11 described below below a predetermined amount. In this case, a water replenishment lamp 10 that is turned on is arranged. The amount of water in the water supply tank 11 can also be confirmed by visual inspection through the water level panel 2. A lid 6 is attached to the upper opening of the humidifier housing 5 so as to be freely opened and closed. 31 in the figure is a release button for releasing the engagement between the lid 6 and the humidifier housing 5 and enabling the lid 6 to be opened. 11 can be removed.

  The humidifier is provided with a water supply tank 11 for storing water, and a steam generator 12 for heating and evaporating the water supplied from the water supply tank 11. The steam generation unit 12 is formed by a hook 13 to which water is supplied from the water supply tank 11 and a heater 14 disposed on the outer peripheral surface of the hook 13. Above the steam generation part 12, a steam guide cylinder 15 opened downward is held in an upright state, and the upper opening of the steam generator 13 and the lower opening of the steam guide cylinder 15 communicate with each other. The steam generated in the steam generating section 12 is guided to the upper part of the steam guide cylinder 15. A connection port 29 is opened in the upper side wall of the steam guide cylinder 15, and one end side of the steam pipe 16 made of a rubber material is connected to the connection port 29. And since the other end side of the steam pipe 16 is connected to the steam discharge port 17 opened in the front of the humidifier housing 5, the steam generated in the steam generation part 12 is the steam guide cylinder 15 and the steam. It is discharged from the steam discharge port 17 to the outside through the pipe 16.

  Moreover, in the humidifier of this example, the nano mist generating part 18 is incorporated above the steam pipe 16. The nanomist generator 18 uses an electrostatic atomization mechanism, and steam generated by the steam generator 12 via a connection pipe 19 inserted in the middle of the path of the steam pipe 16 and connected in communication. A part of the water is introduced and water is supplied by condensation, and a nano-size mist (hereinafter referred to as nano mist) is generated using an electrostatic atomization mechanism based on the water. Specifically, as the electrostatic atomization mechanism, a plurality of rod-shaped members made of a porous body are formed in a casing 20 that forms the outer shell of the nanomist generating unit 18, and from the proximal side to the distal side by capillary action. A water transport member 21 that transports water, a water application electrode 22 that holds the water transport member 21 and applies a voltage to water supplied by the water transport member 21, and the plurality of water transport members 21 The opposite electrode 23 located opposite to each other constitutes a main body, and the tip of the water transport member 21 is generated by a high voltage electric field generated by applying a high voltage between the water application electrode 22 and the counter electrode 23. Electrostatic atomization occurs in the water conveyed to the side, and nanomist is generated. A front end portion of the housing 20 is exposed above the vapor discharge port 17 on the front surface of the humidifier housing 5, and the housing is connected via the nanomist discharge port 24 opened at the front end portion of the housing 20. The nano mist discharged from the water application electrode 22 side toward the counter electrode 23 side in 20 is discharged to the outside. Here, the vapor discharged from the vapor discharge port 17 has a particle size of several μm or more, whereas the nanomist discharged from the nanomist discharge port 24 has a particle size of about 1 to several tens of nm. By being properly discharged, moisture can be further increased by exposure to nanomist after exposure to steam to replenish moisture in the air to human skin and throat in a short time to near saturation. . In addition, the gap on the surface of the human stratum corneum is several tens of nanometers. However, in the humidifier of this example, the nano mist is set to generate a large number of nanometers with a particle size of several tens of nanometers. Thus, moisture can be replenished even to the back of the gap on the stratum corneum surface. Furthermore, since nano mist easily scatters, it has an advantage that it can reach far away in the room, and since it is highly charged, it can easily adhere to the skin.

  Next, the structure of the blower pipe 26, which is a characteristic configuration of the present invention, will be described. The humidifier of this example incorporates a fan motor unit 25 as a blower unit 30 that introduces air from the outside through the filter case 4 described above and applies an upward blowing pressure thereto. The blower pipe 26 whose upper and lower ends are opened is held in an upright position. And since the upper end opening of the fan motor part 25 and the lower end opening of the ventilation pipe 26 are connected, the air taken in from the outside seems to be sent out through the ventilation pipe 26 by the ventilation pressure of the fan motor part 25. It has become. The blower pipe 26 intersects with the steam pipe 16 on the upper side of the intermediate part and penetrates further upward, and its upper end opening is connected to the nanomist generating part 18 in communication. Further, since the blower port 27 is opened at the intersection of the blower pipe 26 and the steam pipe 16, a part of the air sent upward by the fan motor unit 25 is inside the steam pipe 16 via the blower port 27. The remaining air is discharged into the nano mist generating unit 18 through the upper end opening. The air discharged into the steam pipe 16 is mixed with the steam in the middle of being sent to the steam discharge port 17 in the steam passage 28 which is the internal space of the steam pipe 16, and the temperature of the steam is reduced by this mixing. At the same time, the steam is strongly attracted from the steam discharge port 17 to the outside. The air discharged into the nanomist generator 18 is mixed with the nanomist generated by the electrostatic atomization phenomenon, and strongly attracts the nanomist from the nanomist discharge port 24 to the outside.

  That is, in the humidifier of this example, the blower pipe 26 intersects with the steam passage 28 of the steam pipe 16, and the blower port 27 is opened at the blower pipe 26 at the intersecting portion, so that the fan motor Since the air blown from the section 25 is sent into the steam passage 28 through the blower port 27 and the temperature of the steam is reduced by mixing, the steam discharged from the steam discharge port 17 causes the user to burn It will prevent harm.

  4 is an enlarged view of the main part of FIG. 1, and FIG. 5 is a cross-sectional view taken along the line AA of FIG. 4. As is clear from each figure, the air outlet 27 for sending air into the steam pipe 16 is shown in FIG. The air pipe 26 is opened at the side wall. As a result, even if condensed water is generated in the air blowing port 27 and its surroundings, it is difficult for the condensed water to penetrate into the air blowing pipe 26 and the condensed water is prevented from passing through the air blowing pipe 26 and reaching the fan motor unit 25. Has been. Moreover, the opening direction of the air outlet 27 is provided in substantially the same direction as the direction in which the steam is sent out in the steam passage 28 of the steam pipe 16 (the direction of the arrow in FIG. 4), and at least the direction in which the steam is sent out in this way. By providing in a direction that does not oppose, the condensed water is more reliably prevented from entering the blower pipe 26 via the blower port 27. As the shape of the air outlet 27, it is preferable to form a round or square opening in a mesh shape in which a plurality of rows are arranged in the vertical and horizontal directions. The air outlet 27 of this example has a shape in which 5 × 3 rows of square-shaped openings each having a side of about 2.5 mm are arranged in the vertical and horizontal directions. Intrusion into the blower pipe 26 from 27 is further reliably prevented.

  Furthermore, in this example, in addition to opening the blower port 27 in a direction substantially parallel to the direction in which the steam is sent out (that is, in the direction facing the steam discharge port 17 side), as described above, When the humidifier is viewed from the outside, the blower port 27 is formed so that more than half of the blower port 27 is visible from the steam discharge port 17 (see FIG. 6). Thereby, the air sent out from the blower port 27 is smoothly discharged to the outside from the steam discharge port 17 without being substantially cut off, and thereby the steam is strongly attracted toward the outside, and the steam temperature is efficient. Can be reduced. In addition, when the air sent out from the blower port 27 hits the inner peripheral wall of the steam passage 28, the portion is cooled and it becomes easy to generate condensed water. By smoothly discharging from the outlet 17, the generation of this dew condensation water is also suppressed. In addition, in this example, as shown in FIG. 4, a predetermined distance D is provided between the lower end of the blower port 27 and the inner peripheral wall of the steam passage 28 at the intersection of the blower pipe 26 and the steam passage 28. Therefore, even if the dew condensation water generated on the inner peripheral wall of the steam passage 28 forms a puddle, it is prevented from entering the blower pipe 26 through the blower port 27.

  If it is intended to prevent the intrusion of condensed water into the blower pipe 26 more reliably, water repellent means for making it difficult for water to adhere to the outer peripheral wall of the blower pipe 26 at the intersection of the blower pipe 26 and the steam passage 28. It is also preferable to provide Specifically, it is conceivable that the outer peripheral wall of the blower pipe 26 is subjected to silicon coating or Teflon (R) processing, or the surface is finished by mirror polishing although it is an inexpensive method. If water adheres to the outer peripheral wall of the blower pipe 26, condensation at that portion may be promoted and a large amount of condensed water may be generated. However, by providing the water repellent means, Generation | occurrence | production of condensed water is suppressed and invasion of condensed water from the ventilation port 27 is prevented more reliably.

  Next, another humidifier according to the embodiment of the present invention will be described. Since the basic configuration of the other example is substantially the same as the configuration of the above-described example, the description of the corresponding configuration is omitted, and only the configuration that is different will be described below. As schematically shown in FIG. 7A, the blower pipe 26 of the humidifier of the present example intersects the steam pipe 16, that is, the steam passage 28 that is the internal space of the steam pipe 16, substantially perpendicularly. A portion closer to the fan motor unit 25 than the portion is refracted at a substantially right angle. By making the blower pipe 26 into the shape, the air sent out by the fan motor unit 25 is refracted substantially at right angles, the blower pipe 26 opened at the intersecting portion of the blower pipe 26, and steam. The steam is discharged from the steam discharge port 17 through a substantially crank-type flow path that sequentially passes through the steam passage 28 in the pipe 26. By forming the flow path in the crank shape as described above, the dew condensation water in the steam passage 28 is further reliably prevented from entering the fan motor unit 25 through the blower pipe 26. . FIG. 7B shows a case where the refrigeration pipe 26 is refracted so that its refraction angle exceeds a right angle. By setting the refraction angle of the blast pipe 26 large in this way, the dew condensation water is shown. The effect of preventing intrusion can be further increased.
