Description

  The present invention relates to a humidifier, and more particularly to an ultrasonic humidifier in which a float that floats a vibrator that forms water particles is integrally coupled.

  If you continue to inhale the dry air indoors while living indoors for a long time, it will cause various respiratory diseases. Therefore, in order to maintain the indoor humidity at an appropriate level, a humidifier that uses water to be sprayed into the room is used.

  In general, a commonly used ultrasonic humidifier adds an ultrasonic signal generated by an electrical circuit to a vibrator that is submerged in water, and the vibrator vibrates to generate ultrasonic waves. Due to the vibration effect, water is sprayed as fine particles (water vapor).

  FIG. 1 shows the configuration of a humidifier according to the prior art.

  According to the above drawings, the ultrasonic humidifier according to the prior art is roughly divided into a water storage tank 10 for storing water, a base 20 provided with various parts such as a vibrator and a blower, and particulate water is discharged to the outside. It comprises a spray tube 30 and a spray nozzle 32 that guide it as described above.

  The water storage tank 10 is provided with a lid 12 for introducing water. The lid 12 is provided with a drain port 14. Since a spring (not shown) is provided on the inner side of the drain port 14, the drain port 14 is pushed up to the outside of the lid 12 in a normal state, whereby the space between the drain port 14 and the lid 12 is pushed. To prevent water from flowing out of the water storage tank 10.

  The base 20 includes a vibrator 24 for making water into particles, a circuit unit (not shown) that is electrically connected to the vibrator 24 and supplies electric signals and power to the vibrator 24, and is made into particles. In order to discharge water to the outside, a blower 28 that generates an air flow is included. When the water storage tank 10 is seated on the base 20, a protrusion 22 for pushing the drain port 14 into the water storage tank 10 is formed.

  The spray pipe 30 is formed in a substantially cylindrical shape, and serves to guide the particulate water to be discharged to the outside by the air flow generated by the blower 28. The spray nozzle 32 is sandwiched between the upper sides of the spray tube 30 and is configured to be rotatable in a desired direction so that the user can change the direction in which the water vapor is discharged.

  If the operation by the ultrasonic humidifier according to the prior art is seen, if the user raises the water storage tank 10 in which water is stored on the base 20, the protrusion 22 provided on the bottom of the base 20 is provided on the lid 12. The drain outlet 14 is pushed into the inside of the water storage tank 10. At this time, a space is formed between the drain port 14 and the lid 12, and the water in the water storage tank 10 flows out to the water storage unit 26 provided with the vibrator 24. When the user operates the humidifier, the vibrator 24 becomes water particles, and when the blower 28 is activated to generate an air flow, water vapor is generated through the spray tube 30 and the spray nozzle 32. It is discharged outside.

  However, the conventional techniques as described above have the following problems.

  In other words, if the conventional ultrasonic humidifier is used continuously, bacteria, spiders, etc. propagate in the water stored in the water storage section 26 of the water storage tank 10 and the base 20 to cause contamination. . Therefore, it becomes a cause of indoor air pollution.

  In order to prevent this, the water tank 10 and the base 20 must be washed continuously, but it is difficult to cleanly clean the water tank because of the structure of the water tank. The water storage section 26 provided with the vibrator 24 also requires continuous cleaning. However, in order to clean this, the entire base 20 has to be moved and is completely insulated. Water may soak into circuit boards that are not connected, causing the entire humidifier to malfunction. Therefore, when the user cannot keep the humidifier clean, the already contaminated water is mixed with the newly exchanged water to humidify the room air, thereby further deteriorating the contamination state of the room air.

JP 2007-248038 A

  In order to solve the above-described problems of the prior art, the present invention provides a humidifier that adjusts the humidity of room air so that the water storage container for storing water can be conveniently cleaned to maintain a sanitary indoor environment. The purpose is to do.

  Another object of the present invention is to provide a humidifier capable of fine humidification in which only fine particles among vapor particles generated by an ultrasonic vibrator are supplied to the outside.

In order to achieve the above-described object, the present invention stores water, can open and close a water storage container whose upper surface is open, and an upper part of the water storage container, and discharges steam generated from the inside of the water storage container to the outside. A cap portion provided with a discharge port, a guide portion provided at a lower end of the cap portion, a float guided by the guide portion to move up and down, and water is formed into particles and provided at a lower portion of the float. A vibrator interlocking with the float, and the guide portion is provided at a vertical guide portion for guiding the float and a lower end portion of the guide portion to regulate a minimum position of the vibrator. And a bottom surface .

  The humidifier according to the present invention further includes a water level sensor for sensing the water level and controlling on / off of the vibrator.

  The cap portion includes a lower plate in which a suction port is formed, and an upper plate in which a discharge port is formed at a position corresponding to the suction port. The suction port and the discharge port are connected to each other. The steam generated from the inside of the water storage container forms an outlet for discharging to the outside.

  In addition, a fan for generating an air flow in the water storage container is provided in the cap portion. Here, it is preferable that the air flow generated by the fan forms a swirl flow inside the water storage container.

  According to another embodiment of the present invention, a handle is provided on the top of the cap portion.

  According to still another embodiment of the present invention, the guide portion is formed in a cylindrical shape with a slit formed in a longitudinal direction, the bottom surface is formed in a cylindrical guide portion, and the float is in a ring shape. The vibrator is formed integrally connected to the float at the lower center of the float, and the guide portion is sandwiched in a space formed between the float and the vibrator, and moves up and down depending on the water level. The bottom surface regulates the lowest position of the vibrator.

  In the ultrasonic humidifier according to the present invention, since the steam generator is provided at the lower portion of the cap, the cap can be separated from the water storage container only by the water storage container whose upper surface is substantially opened. Is possible. Therefore, it is possible to expect an advantage that the inside of the water storage container can be cleaned cleanly.

  And according to this invention, it is possible to comprise so that the airflow formed with a fan may form a swirl flow inside a water storage container. If a swirl flow is formed inside the water storage container, relatively large and heavy vapor particles fall downward due to their own weight, and only fine particles can be supplied to the outside through the discharge port. The advantage of being possible is also expected.

It is sectional drawing which shows the structure of the ultrasonic humidifier which concerns on a prior art. 1 is a perspective view showing an overall overview of an ultrasonic humidifier according to a specific embodiment of the present invention. It is a schematic sectional drawing which shows the internal structure of the ultrasonic humidifier which concerns on specific embodiment of this invention. It is a disassembled state perspective view of the humidifier concerning the present invention.

  Hereinafter, preferred embodiments of a humidifier according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 2 is a perspective view showing an overall appearance of a humidifier according to a specific embodiment of the present invention, and FIG. 3 is a schematic cross-sectional view showing an internal configuration of the humidifier according to a specific embodiment of the present invention. FIG. 4 is an exploded perspective view of the humidifier according to the present invention.

  As shown in the drawings, the humidifier according to the present embodiment stores water, opens a water storage container 200 opened on the upper surface, and opens and closes the upper part of the water storage container 200, thereby forming a discharge port through which steam is discharged. The cap part 300 and the steam generation part 100 which is coupled to the lower end of the cap part 300 and makes water into particles are configured.

  The water storage container 200 of this embodiment is a substantially cylindrical container, and the upper surface is opened. Thus, since the entire upper surface of the water storage container 200 is opened, the inside of the water storage container 200 is actually very easy to clean. The upper surface of the water storage container 200 is opened and closed by the cap unit 300. That is, the cap part 300 can be separated and water can be supplied to the inside of the water storage container 200 or the inside can be cleaned.

  The steam generation unit 100 of this embodiment is attached to the lower part of the cap unit 300. Therefore, if the cap part 300 is separated from the water storage container 200, the steam generation part 100 is also separated from the water storage container 200 together with the cap part 300 as shown in FIG.

  The steam generation unit 100 includes a vibrator 110 that generates ultrasonic waves to form water particles, a water level sensor 130 that senses the water level and interrupts the operation of the humidifier, and the vibrator 110. A float 150 having a constant buoyancy to maintain a depth of underwater.

  The float 150 has a substantially ring shape. The vibrator 110 is coupled to the float 150 at the center of the float 150. For example, when the connecting arm 152 formed inside the float 150 is coupled to the vibrator 110, the float 150 and the vibrator 110 can be coupled to each other. At this time, the vibrator 110 is provided below the float 150 by a certain height. That is, when the float 150 floats on the surface of the water, the vibrator 110 is provided so as to be submerged in water having a predetermined depth. The water level detection sensor 130 is provided on the upper surface of the vibrator 110.

  The vibrator 110 and the float 150 are guided to move in the vertical direction by a guide portion 170 attached to the bottom surface of the cap portion 300. The guide portion 170 has a substantially thin cylindrical shape and is provided with a guide portion 172 formed by forming a slit in the longitudinal direction in the central portion. The inside of the lower end of the guide portion 172 of the guide portion 170 forms a bottom surface 174.

  The guide part 172 is sandwiched between spaces formed between the inside of the float 150 and the outside of the vibrator 110, and the vibrator 110 and the float 150 are moved up and down by changing the water level inside the water storage container 200. It plays a role of guiding so that it can move in the direction. When the water in the water storage container 200 falls below a certain amount on the bottom surface 174, the vibrator 110 is seated. That is, the lowest position of the vibrator 110 is regulated by the bottom surface 174. And the upper end part of the said guide part 172 is couple | bonded with the lower end of the cap part 300 mentioned later. Therefore, when the handle 350 of the cap unit 300 is lifted, the cap unit 300, the guide unit 170, and the steam generation unit 100 are lifted together.

  In the illustrated embodiment, the vibrator 110 is located inside the guide portion 172, and the float 150 connected with the vibrator 110 is located outside the guide portion 172. Therefore, when the cap part 300 is lifted, the vibrator 110 and the float 150 can be removed from the water storage container 200 together with the guide part 170 attached to the lower end part of the cap part 300.

  The water level sensor 130 is positioned below the float 150 by a certain height. Therefore, if there is not enough water remaining in the water storage container 200 to the extent that the float 150 cannot float the vibrator 110, the water level sensor 130 is exposed to the air and senses that there is no water. Thus, an electric signal is generated in the circuit unit so as to cut off the operation of the vibrator 110.

  The opened upper part of the water storage container 200 is opened and closed by the cap unit 300. The cap unit 300 includes a lower plate 310 in which a suction port 320 is formed, and an upper plate 330 in which a discharge port 340 and a handle 350 are formed. The suction port 320 is formed to be recessed upward so that water vapor is blown outward. The upper plate 330 is formed so that a discharge port 340 formed at a position corresponding to the suction port 320 of the lower plate 310 is recessed downward.

  If the upper plate 330 and the lower plate 310 are connected to each other, the suction port 320 and the discharge port 340 are connected to each other, and the discharge port (A) that discharges the steam generated from the inside of the water storage container 200 to the outside. Form.

  A fan 360 is provided inside the cap unit 300. The fan 360 is for generating an air flow inside the water storage container 200. That is, since a hole is formed in the lower plate 310 corresponding to the portion where the fan 360 is provided, the air flow generated from the fan 360 is supplied into the water storage container 200. A circuit board (circuit unit) 370 for controlling whether or not the fan 360 operates or whether or not the vibrator 110 operates can also be installed inside the cap unit 300.

  Therefore, when the user operates the humidifier, an air flow is generated by the fan 360 provided in the cap unit 300, and a hole (on the bottom surface of the lower plate 310 provided with the fan 360 ( An air flow is supplied to the inside of the water storage container 200 by a not-shown). At this time, the water vapor generated by the vibrator 110 due to the generated air flow is blown to the outside along the discharge port (A) including the suction port 320 and the discharge port 340. That is, the suction port 320 and the discharge port 340 cooperate to guide the water vapor to the outside.

  Here, the air flow supplied to the inside of the water storage container 200 by the fan 360 will be described. It is preferable that the air flow generated from the fan 360 forms a swirling flow inside the water storage container 200. When a swirl flow is generated inside the water storage container 200, among the steam particles, relatively light particles, that is, the finest particles come out to the outside through the discharge port (A). Heavier particles will sink downward due to their own weight. Therefore, the swirl flow generated from the inside of the water storage container 200 by the fan 360 allows only fine vapor particles to escape through the discharge port (A), so that an advantage that fine humidification can be substantially achieved can be expected.

  Here, in order to allow the air flow formed by the fan 360 to form a swirl flow inside the water storage container 200, the position of the fan 360 is inclined along the circumferential direction of the water storage container 200. It is also possible to adjust, and another guide may be formed on the lower plate 310 so that the air flow generated by the fan 360 flows along the circumferential direction inside the water storage container 200.

  A handle 350 is formed above the upper plate 330. The handle 350 is coupled to both ends of the upper plate 330. Since a space is formed in the central portion of the handle 350 and the central portion of the upper plate 330, the user can put the hand into the space. Therefore, the cap part 300 can be easily lifted.

  A hooking protrusion 210 is formed at the upper end inside each side of the water storage container 200. A latching slit 380 is formed at the lower end of both side surfaces of the lower plate 310 so that the latching protrusion 210 can be sandwiched. The latching slit 380 includes an insertion portion 382 having a groove formed in the vertical direction and a seating portion 384 having a groove formed in a direction perpendicular to the insertion portion 382. When the user closes the water storage container 200 using the cap unit 300, the latch protrusion 210 formed on the water storage container 200 must be closed so as to enter the insertion part 382 formed on the lower plate 310. Don't be. And if the said cap part 300 is rotated in the direction in which the said seating part 384 was formed, the said cap part 300 and the water storage container 200 will be latched. Accordingly, when the cap unit 300 is lifted in a state where the cap unit 300 and the water storage container 200 are hooked, the water storage container 200 is also lifted together.

  When the cap unit 300 is to be released while the cap unit 300 and the water storage container 200 are engaged, the above-described operation may be performed in reverse. That is, the cap 300 may be rotated in the opposite direction in which the seating portion 384 is formed and positioned at the position where the insertion portion 382 is formed, and then the cap 300 is lifted.

  The vibrator 110 for generating steam and the circuit unit 370 are electrically connected. As an example, it can be considered that they are connected by electric wires. At this time, it is necessary to use a wire that is sufficiently waterproof, and the connecting portion with the vibrator 110 must be sufficiently waterproofed by, for example, silicon coating.

  Hereinafter, the operation of the humidifier according to the specific embodiment of the present invention as described above will be described in detail. First, a process in which the humidifier operates using the humidifier according to the present invention will be described in detail.

  When a certain amount of water is stored in the water storage container 200 and the user operates the operation button of the humidifier, an electrical signal generated from the circuit unit 370 is sent to the vibrator 110. As a result, when the vibrator 110 vibrates and generates ultrasonic waves, water is atomized and sprayed. Then, an air flow is generated inside the water storage container 200 while the fan 360 provided in the cap unit 300 operates. At this time, the particulate water (water vapor) is ejected to the outside through the suction port 320 of the lower plate 310 and the discharge port 340 of the upper plate 330 by the air flow generated by the fan 360.

  Here, as described above, if the air flow generated by the fan 360 forms a swirl flow inside the water storage container 200, the vapor particles generated by the vibrator 110 are relatively large. The heavy particles fall downward due to their own weight while turning, and only relatively small and fine particles can be supplied to the outside through the discharge port (A).

  When the water level of the water storage container 200 gradually decreases due to the operation of the vibrator 110, the float 150 and the vibrator 110 descend downward along the guide part 172 of the guide part 170. If the amount of water remaining in the water storage container 200 is less than a certain amount, the vibrator 110 is seated on the bottom surface 174 of the guide portion 170. When the humidifier continues to operate and the water level becomes lower, the water level detection sensor 130 provided in the steam generation unit 100 detects this, and transmits this signal to the circuit unit 370. The circuit unit 370 that has received the transmission of the signal transmits an electrical signal for stopping the operation of the vibrator 110, and the vibrator 110 stops operating.

  Next, the process of cleaning the humidifier according to the present invention will be described in detail.

  When all the water stored in the water storage container 200 is used or the user is to clean the humidifier, the handle 350 formed on the upper plate 330 is rotated in the opposite direction in which the seating portion 384 is formed, When lifted along the insertion portion 382, the cap portion 300, the guide portion 170 sandwiched between the lower plates 310, and the steam generating portion 100 placed on the bottom surface 174 of the guide portion 170 are lifted together. At this time, the guide portion 170 sandwiched between the lower plates 310 can also be separated. Therefore, the water storage container 200 and the guide part 170 from which the above parts are separated can be easily cleaned by the user. In addition, the steam generating unit 100 is separated from the above components and is easily cleaned. Therefore, since the user can easily wash the water storage container 200 and the steam generation unit 100, clean indoor air can be maintained by using the humidifier as clean component management becomes possible.

  The right of the present invention is not limited to the above-described embodiment, but is defined by what is described in the claims, and those who have ordinary knowledge in the field of the present invention fall within the scope of the right described in the claims. It is obvious that various modifications and adaptations are possible.
