Description

  The present invention relates to an air purifier that generates an air flow and cleans a local space in a room.

  Conventionally, as this type of air purifier, there has been a type in which a clean air flow is generated on a bed from a blow-out portion provided on the head side of the bed to clean the periphery of the sleeping person's head. (For example, refer to Patent Document 1).

  In FIG. 5, the air purifier includes a main body portion 2 that extends from the head side of the bed portion 1 to the lower portion of the bed portion 1. Inside the main body portion 2, air blowing means (not shown) and air flow cleaning means ( (Not shown) is arranged. The main body 2 is provided with a suction part 5, and a blowout port 6 is provided on the head side of the bed part 1 of the main body 2. The air from which dust has been removed by the airflow cleaning means is blown out from the outlet 6 as a cleaned airflow 7. The cleaned airflow 7 is caused to flow toward the head of the sleeper 8 on the bed 1. The suspended dust around the head of the sleeping person 8 is carried to the foot side by the cleaning airflow 7 and the head around the sleeping person 8 is cleaned.

  Further, the air flow cleaning means removes dust, and at the same time, adjusts the air quality such as adjustment of temperature and humidity, addition of negative ions, and addition of fragrance. Since the cleaned airflow 7 with adjusted air quality hits the head of the sleeping person 8 and is simultaneously sucked into the sleeping person 8 by breathing, the comfort of the sleeping person 8 is enhanced.

JP 2000-181067 A

  However, conventional air purifiers can remove suspended dust that floats for a long time and easily rides on the airflow from the sleeper's head. In order to remove the floating dust, there was a problem that the cleaning air flow had to be strengthened.

  For example, sleeping sleepers can be prevented from inhaling dust such as pollen and being awakened by an allergic reaction, or at the moment of awakening when the allergic reaction becomes excessive due to the predominance of parasympathetic nerves. In order to prevent the suction of dust, it is necessary to remove not only floating dust but also semi-floating dust from around the head of the bedridden, but because the enhanced cleaning airflow hits the sleeping bedtime, Had the problem of feeling uncomfortable and disturbing sleep. Wearing a mask or the like can prevent a sleeping person from sucking floating dust and semi-floating dust, but wearing the mask itself is uncomfortable and has a problem that sleep is disturbed.

  In addition, the airflow that has been adjusted for air quality immediately flows from the head of the sleeping person to the feet, and at the same time, the airflow is restored to its original state by mixing with the surrounding air. Therefore, even if the air quality is adjusted by the airflow cleaning means, the air quality around the head of the sleeping person does not change greatly, and there is a problem that it is difficult to improve comfort.

  The present invention solves the above-described conventional problems, and removes and cleans floating dust and semi-floating dust around the head without disturbing sleep of the sleeper, and simultaneously adjusts air quality around the sleeper's head. An object of the present invention is to provide an air purifier that can enhance comfort.

  In order to solve the above-described conventional problems, the air cleaner of the present invention is configured such that a cover portion is provided above the sleeper's head so that the cleaned airflow collides with the inner surface of the cover portion.

  By providing the cover part above the sleeping person's head, it is possible to prevent the semi-floating dust from falling around the sleeping person's head. Moreover, a turbulent flow is generated inside the cover part by causing the cleaned air current to collide with the inner surface of the cover part. When the turbulent flow occurs, the cleaning airflow becomes a gentle uniform airflow that flows almost uniformly from the entire opening surface at the time of flowing out from the opening surface that opens toward the head of the sleeping person on the bottom surface side of the cover portion. Since the airflow is a uniform airflow that flows from the entire opening surface, all the floating dust approaching the head periphery is a purified airflow, and the airborne dust is easy to get on the airflow, so that it is separated from the sleeper's head periphery. For this reason, the circumference | surroundings of a sleeper's head can be cleaned, without a sleeper's sleep being disturbed by a strong cleaning airflow.

  Further, since the speed of the cleaning airflow is reduced by being a uniform airflow, it stays around the head of the sleeping person for a long time, while the cleaning airflow is prevented from being mixed with the surrounding air by the cover portion. Therefore, the air quality around the head can be adjusted because the air reaches the bedside of the sleeping person while maintaining the air quality adjusted by the air flow cleaning means.

  The air purifier of the present invention does not need to generate a strong cleaning air flow, so that it does not disturb the sleep of the sleeper and can adjust the air quality around the head of the sleeper at the same time, so that the comfort of the sleeper is improved. Can be increased.

  1st invention is comprised in the main-body part arrange | positioned at the back of the head of a sleeper, the ventilation means incorporated in the said main-body part, the airflow cleaning means incorporated in the said main-body part, and the said main-body part. A blowout port that blows out a purified airflow; a suction port configured in the main body portion; and a cover portion that is attached to the main body portion so as to cover an upper part of the sleeping person's head, and the cleaned airflow is the cover By adopting a configuration in which the air is blown out so as to collide with the inner surface of the part, it is possible to prevent the semi-floating dust, in which particles are easily dropped by the cover part, from falling around the sleeping person's head. In addition, suspended dust that floats for a long time is carried away in a uniform, low-speed, clean airflow, so that it can be prevented from entering around the head. Therefore, the sleeper's head periphery can be cleaned without impairing sleep of the sleeper due to the strong cleaning airflow. Further, since the purified airflow stays around the head for a long time and does not mix with the surrounding air, the air quality around the head can be adjusted and the comfort can be enhanced.

In the second aspect of the invention, in particular, the blowout port of the first aspect of the invention is configured to face the inner surface of the cover portion, so that the cleaned air current more reliably collides with the inner surface of the cover portion, so that turbulent flow is generated. It is made uniform. In addition, the head of the sleeping person after the cleaning airflow has entrained the air around the cover portion, which can occur when the cleaning airflow is blown in from the outside of the cover portion provided so that the outlet does not face the inner surface of the cover portion By blowing around, the floating dust around the cover is not blown around the head of the sleeping person. Therefore, it is possible to clean the area around the head of the sleeping person. Further, since the cleaned airflow stays around the head for a long time, the air quality around the head can be adjusted and the comfort can be enhanced.

  According to the third aspect of the invention, in particular, the cover portion of the first aspect of the present invention is configured from a plurality of surfaces and has a corner portion on the inner surface, so that turbulent flow is easily generated by the corner portion, so that the cleaning airflow is more It is made uniform. The cleaned airflow becomes a gentle uniform airflow that flows from the entire opening surface of the cover portion, so that the sleeper's head and its surroundings can be cleaned without impeding the sleep of the sleeper due to the strong cleaned airflow. Further, since the cleaned airflow stays around the head for a long time, the air quality around the head can be adjusted and the comfort can be enhanced.

  According to the fourth aspect of the invention, the cover portion of the first aspect of the invention has a horizontal rib structure inside the lower end portion, so that it flows along the inner surface of the cover portion after colliding with the inner surface of the cover portion. A part of the cleaning air flow toward the opening surface of the cover portion collides with the rib structure at the end of the cover portion and changes its direction, so that the non-uniform cleaning air flow is prevented from flowing out from the opening surface of the cover portion. The sleep of the sleeper is not disturbed by the strong cleaning airflow.

  In the fifth aspect of the invention, in particular, the cover portion zenith portion is opened by blowing out the blowout port of the first invention so that the cleaning air current collides with the cover portion zenith portion located on the uppermost part of the inner surface of the cover portion. Since it is farthest from the surface, the cleaning airflow collides with the inner surface of the cover part more times than the case where it first collides with the part other than the top part of the cover part, such as the side surface of the cover part, and then from the opening surface. It begins to flow out. A turbulent flow is generated each time the cleaned airflow collides with the inner surface of the cover portion, and the cleaned airflow is made more uniform. Since the uniformed cleaning airflow is blown out from the opening surface of the cover portion, the surroundings of the sleeping person's head can be cleaned without hitting the sleeping person's sleep due to the strong cleaning airflow. Further, since the cleaned airflow stays around the head for a long time, the air quality around the head can be adjusted and the comfort can be enhanced.

  According to the sixth aspect of the invention, in particular, the outlet of the first aspect of the invention is configured so that the cleaned airflow collides with each other inside the outlet cover portion in a plurality of directions, thereby preventing the cleaned airflow from colliding with the inner surface of the cover portion. In addition, since the turbulent flow is generated by the collision of the cleaned airflows, the cleaned airflow is further uniformized. Since the uniformed cleaning airflow is blown out from the opening surface of the cover portion, the surroundings of the sleeping person's head can be cleaned without hitting the sleeping person's sleep due to the strong cleaning airflow. Further, since the cleaned airflow stays around the head for a long time, the air quality around the head can be adjusted and the comfort can be enhanced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment 1)
FIG. 1 shows a perspective view of an air cleaner according to Embodiment 1 of the present invention.

  In FIG. 1, the air cleaner has a main body portion 10, and the main body portion 10 is disposed on the back side of the sleeping person 11. A blower 12 (not shown) and an air flow cleaner 13 (not shown) are arranged in the main body 10. A blow-out port 14 is provided in front of the main body 10, and a suction port 15 (not shown) is provided in the back of the main body 10. A cleaning air flow 16 is blown out from the outlet 14 toward the head of the sleeping person 11.

A cover portion 17 is provided on the front side of the main body portion 10. The outlet 14 is the cover 1
7, the cleaning airflow 16 collides with the inner surface of the cover portion 17. The cover portion 17 is opened toward the head of the bedridden 11 on the bottom surface side, and the cleaned air flow 16 made uniform from the entire opening surface flows out as a uniform air flow 18.

  FIG. 2 shows a side view of the air cleaner according to Embodiment 1 of the present invention. In FIG. 2, the cover portion 17 is arranged so as to cover the upper part of the head of the lying sleeper 11 and includes the eyes, nose, and mouth of the sleeper 11 that causes an allergic reaction by contact with an allergen such as pollen. The entire head is hidden behind the cover 17 when viewed from above.

  The main body 10 is provided with a blowing means 12 and an air flow cleaning means 13. A blowing port 14 is provided on the front surface of the main body 10, and a suction part 15 is provided on the back of the main body 10. A cleaning air flow 16 is blown out from the outlet 14.

  The cover portion 17 is composed of a plurality of surfaces, and a corner portion 19 is formed on the inner surface of the cover portion 17. Further, a substantially horizontal rib structure 20 is provided on the inner surface of the lower end of the cover portion 17. A turbulent flow 21 is generated at the corner 19 and the rib structure 20.

  The cleaned air flow 16 collides with the inner surface of the cover portion 17 and changes its direction. Further, a turbulent flow 21 is generated along with the collision.

  Further, floating dust 22 (not shown) is suspended around the cover portion 17. At the same time, semi-floating dust 23 is falling from above the cover portion 17.

  About the air cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. First, the sleeping person 11 activates the air cleaner in a lying state and operates the air blowing means 12.

  Since the cover portion 17 covers the upper part of the head of the sleeper 11, the semi-floating dust 23 that is about to fall around the head of the sleeper 11 hits the outer surface of the cover portion 17. 11 will not fall around the head.

  On the other hand, air is sucked from the outlet 14 by the air blowing means 12, and the air is cleaned by the airflow cleaning means 13 and then blown out from the outlet 14 as a cleaned airflow 16 so as to collide with the inner surface of the cover portion 17. .

  When the cleaning airflow 16 collides with the inner surface of the cover portion 17 facing the outlet 14, it flows so as to spread in all directions, and at the same time, a turbulent flow 21 is generated. The cleaned airflow 16 is made uniform by this collision. Further, the cleaning air flow 16 spreading in all directions is further uniformed by colliding with the inner surface of the cover portion 17 again.

  On the other hand, a part of the collided cleaning airflow 16 flows along the inner surface of the cover portion 17. However, since this cleaned air flow 16 hits the corners 19 and the rib structure 20, the turbulent flow 21 is particularly likely to be generated and the uniformization proceeds. At the same time, the rib structure 20 changes the direction of the cleaned airflow 16 flowing along the inner surface of the cover portion 17, and the cleaned airflow 16 does not flow out of the opening surface of the cover portion 17 without being made uniform.

The cleaned air flow 16 made uniform by the collision with the inner surface of the cover portion 17 flows out from the entire opening surface of the cover portion 17 as a uniform air flow 18 having a gentle flow velocity. The suspended dust 22 floats for a long time without falling, and tends to approach the head 11 of the sleeping person 11 by a slight air flow such as the air flow caused by the sleeping person 11, but the cleaning air current 16 is the entire opening surface. Therefore, all the floating dust 22 that approaches the periphery of the head hits the cleaning air flow 16. Since the suspended dust 22 is easy to ride on the airflow, it rides on the cleaned airflow 16 and moves away from the head around the sleeping person 11.

  Thereby, the floating dust 22 can be removed from the head periphery without the sleep of the sleeper 11 being impeded by the strong cleaning airflow 16. Since both the floating dust 22 and the semi-floating dust 23 are removed from around the head of the sleeping person 11, for example, pollen or the like causes an allergic reaction and does not wake up.

  The air flow cleaning means 13 removes dust and adjusts the air quality such as adjusting the temperature and humidity, adding negative ions, and adding fragrance.

  The airflow 16 that has been adjusted in air quality is made uniform by collision with the inner surface of the cover portion 17 and the like. However, since the cover portion 17 prevents the air from surrounding the cover portion 17 from intermingling with the airflow, the cover is prevented. The air flow 16 does not return to the surrounding air state inside the portion 17.

  Further, since the cleaned airflow 16 flowing out from the opening surface of the cover portion 17 is a uniform airflow 18 having a gentle flow velocity, the cleaned airflow 16 stays around the head of the sleeping person 11 for a long time. At the same time, it is sprayed around the head without omission. As a result, the air quality around the head of the sleeping person 11 becomes substantially the same as the air quality of the cleaned air current 16 adjusted by the air current cleaning means 13, and the comfort of the sleeping person 11 is further enhanced.

  Subsequently, the sleeper 11 wakes up after sleeping. Since the parasympathetic nerve is dominant at the moment of waking, the allergic reaction becomes excessive. However, since the area around the head of the sleeping person 11 continues to be cleaned from sleep, no allergic reaction occurs. Therefore, the sleeper 11 can be awakened clearly and get up after the sympathetic nerve becomes dominant.

  In this embodiment, the air outlet 14 is configured to face the side surface of the cover portion 17 and is configured to blow out the cleaning airflow 16 in the horizontal direction. However, the air cleaner shown in FIG. As in another example of the configuration, the cleaning air flow 16 may be blown and collided with the cover portion zenith portion 24 positioned at the uppermost position on the inner surface of the cover portion 17.

  By causing the cleaned airflow 16 to collide with the cover portion zenith portion 24, a flow turbulent flow 21 is generated so that the cleaned airflow 16 spreads in all directions. On the other hand, a part of the collided cleaning airflow 16 flows along the inner surface of the cover portion 17. However, since the cleaned air flow 16 collides with the cover portion zenith portion 24, even if the cleaned air flow 16 flows along the inner surface of the cover portion 17, it does not reach the opening surface of the cover portion 17 as it is. 17 will collide with the other surface. Therefore, the cleaning airflow 16 collides a plurality of times, and the cleaning airflow can be made more uniform.

  In the present embodiment, the air outlet 14 is configured to face the side surface of the cover portion 17 and is configured to blow the cleaning airflow 16 only toward the opposing surface 25 of the air outlet 14. As in another configuration example of the air cleaner shown in FIG. 4, the cleaned airflow may collide with each other inside the blowing cover portion 17 in a plurality of directions.

  The cleaned air flow 16 is blown out so as to collide with the left and right side surfaces 26 of the cover portion 17 when viewed from above. The cleaned air flow 16 tries to spread in four directions by colliding with the left and right side surfaces 26 of the cover portion 17, but the angle of collision is shallower than the case of colliding with the facing surface 25, so the cleaned air current 16 It is easy to flow along the left and right side surfaces 26, and the cleaned air flow 16 flows toward the facing surface 25 of the outlet 14. When the cleaned air flow 16 reaches the facing surface 25, a collision occurs, whereby the cleaned air flow 16 spreads again in all directions and a turbulent flow 21 is generated.

  However, a part of the impinging cleaning airflow 16 again flows along the facing surface 25. For this reason, the cleaned airflow 16 flowing from each of the left and right side surfaces 26 collides with the center of the facing surface 25. By this collision, the cleaning air flow 16 further spreads and a turbulent flow 21 is also generated. When the air currents collide, the turbulent flow 21 generated on one side becomes a factor that generates the turbulent flow 21 on the other air flow, and this is repeated. Cheap. Therefore, the cleaning air flow 16 is made uniform more quickly.

  Each of the above-described embodiments can be used in appropriate combination as needed, and is not limited to the configuration of the embodiment itself.

  As described above, the air cleaner according to the present invention can be applied to an apparatus that cleans a local space with an air flow.
