Description

  The present invention relates to a blower and a living room equipped with the blower.

  In recent years, general ventilation equipment has been indispensable to appropriately exhaust air from the house and supply air into the house due to high airtightness and high heat insulation against the background of energy saving and comfort improvement. The purpose of general ventilation is to maintain necessary indoor ventilation in order to maintain the indoor environment in the building properly, and to maintain the concentration of pollutants represented by volatile organic compounds below the appropriate level. It is in the measure against sick house by doing.

  Concerning such general ventilation, it is stipulated in the Building Standards Act that ventilation (exhaust from the house and supply to the house) more than 0.5 times per hour is made to function with mechanical power at all times (24 hours). . On the other hand, since a ventilator that performs general ventilation always functions for 24 hours, reduction of power energy and heating / cooling energy generated by ventilation is also required.

As an energy saving method for general ventilation, natural ventilation increases through gaps in houses due to temperature differences between the outside and outside in winter, so the general ventilation is reduced from 0.5 times / hour to 0 in anticipation of the increase in natural ventilation. Measures to reduce 3 times / hour and measures to reduce the indoor ventilation by reducing the indoor concentration by adsorbing or removing volatile organic compounds in the room and reducing the general ventilation by a predetermined amount are also compliant with the law It is recognized as a technique to do.
According to these measures, the general ventilation volume by the mechanical ventilation equipment of 0.5 times / hour legally stipulated can be reduced, and the power and heating / cooling load accompanying general ventilation are reduced to promote energy saving. can do.

  In order to maintain the indoor pollutant concentration below an appropriate level by the general ventilation described above, it is necessary to circulate the air in the house without stagnation.

However, the overall ventilation rate of 0.3 to 0.5 times / hour mentioned above is, for example, a volume of about 50 m ³ in a 12 tatami room, and a small air volume of 15 to 25 m ³ / h. It becomes the air supply amount and the exhaust amount. There is a concern that the airflow in the supply / exhaust of a small amount of air becomes weak and stagnation occurs in the air in the room, and the pollutants remain. In addition, in the winter season, when the outside air is supplied, the air flow becomes a cold draft even though the air volume is small, resulting in uneven temperature distribution in the room, and the air quality and thermal environment cannot be properly maintained in the indoor living area. There was a problem.

  On the other hand, as a conventional ventilation blower, “the inside air and the outside air mixed in the mixing chamber are agitated by the air supply blower and blown out from the indoor outlet to the room, and from the indoor suction port to the air supply blower. As the leading air path, there has been proposed one that employs means for providing a filter that adsorbs or removes volatile organic compounds from the air flow flowing through the air path (see, for example, Patent Document 1).

  Patent Document 1 relates to air supply in winter: “In winter, a temperature difference between the inside and outside of the room causes an increase in the amount of natural air flow, which can reduce the amount of air supply. Therefore, in winter, the open / close shutter 29 is half-opened. When moved to the position of the state, the opening area of the outdoor suction port 6 and the opening area of the indoor suction port 9 become substantially equal, for example, 50% from the outdoor suction port 6 and 50% from the indoor suction port 9 to 50. % Of air is sucked in, this air is mixed, stirred, and blown into the room from the indoor outlet 8 ".

JP-A-2006-71205 (pages 3 to 5, FIG. 2)

  Patent Document 1 describes a configuration for reducing the amount of air supply in the winter season, but there is a technology or a volatile organic compound that prevents stagnation of polluted materials caused by stagnation of room air due to supply and exhaust of a small amount of air. There has been no disclosure of a technique for securing an effective ventilation conversion amount by means of providing a filter for adsorption or removal, and a technique for ensuring an appropriate effective ventilation conversion amount, or a technique for improving the indoor thermal environment.

  Moreover, from the request | requirement to energy-saving, the ventilation apparatus provided with this ventilation apparatus and this ventilation apparatus which can further reduce ventilation ventilation power and heating / cooling load irrespective of ventilation is desired. Furthermore, in the renovation of buildings with heat-insulated double sashes for the purpose of energy saving, measures against sick houses are also required along with improving the airtight performance of the buildings.

  The present invention has been made against the background of the above-described problems, and an object of the present invention is to provide a blower capable of suppressing deterioration of the indoor environment and a living room equipped with the blower.

  The blower according to the present invention includes a blower main body in which an air inlet and an air outlet are formed, and a plurality of blowers provided in an internal air passage formed between the air inlet and the air outlet. And the air blowing means is divided into a plurality of air blowing units one by one or plural units, and can be switched between operation and stop for each air blowing unit, and the internal air passage is It is divided for each blowing unit and is narrowed from the air intake port toward the air discharge port.

  The living room according to the present invention includes the blower according to the present invention.

  According to the present invention, the indoor air discharged from the blower main body is spread to every corner of the room, thereby eliminating air stagnation and lowering the concentration of pollutants, making the temperature distribution in the room uniform, The heating / cooling load can be reduced. Therefore, deterioration of the indoor environment can be suppressed.

The blower device 1 is installed on the ceiling surface 101 via, for example, an attachment means 50 fixed to the ceiling surface 101 (FIG. 1), and is supplied with power via a ceiling rosette 60.

  In the first embodiment, the air blower main body 3 includes, for example, a mounting surface 3a in which a mounting hole 3a1 that engages with the mounting bracket 50a of the mounting means 50 is formed, and an illumination surface provided on the bottom surface facing the mounting surface 3a. 3b, and the main body side surface 3c which comprises the outer wall of the air blower main body 3, and forms the attachment surface 3a and the illumination surface 3b in a continuous surface.

  The main body side surface 3c is formed with a plurality of openings, and occupies almost half the area of the main body side surface 3c, and is formed with an air intake port 8 for taking in air outside the blower device body 3 into the blower device body 3. . Moreover, the air discharge port 9 which discharges the air inside the air blower main body 3 to the air blower main body 3 exterior is formed in the main body side surface 3c.

  The air intake port 8 and the air discharge port 9 are formed to be opposed with respect to the center of the blower main body 3. The room 100 (FIG. 1) communicates with the inside of the blower main body 3 through the air intake port 8 and the air discharge port 9. The air passage in the blower main body 3 connecting the air intake 8 and the air outlet 9 is referred to as an internal air passage 10. The internal air passage 10 is provided with a main body frame 5 that narrows the cross-sectional area of the internal air passage 10. The main body frame 5 is, for example, a curved flat plate, and is installed so as to narrow the width of the internal air passage 10 of the air discharge port 9 with respect to the air intake 8 side, and the downstream end of the air flow is the wind tunnel 11b. It is located on the entrance side (described later).

  The inner cylinder 7 has a substantially cylindrical shape with both upper and lower ends opened, and is provided at a substantially central portion of the blower main body 3. The inner cylinder 7 is provided at a substantially central portion of the blower main body 3 and divides the internal air passage 10 to narrow the cross-sectional area of the internal air passage 10. When the blower 1 is used, the power supply unit 20 is inserted into the inner cylinder 7. The power supply unit 20 has a substantially cylindrical shape, and includes a power receiving unit 20a and a mounting power feeding unit 20b. The power receiving means 20a is provided on the upper surface of the power supply unit 20, and is connected to the ceiling rosette 60 installed on the ceiling surface 101 for power distribution. The attachment power supply means 20b is provided on the lower surface of the power supply unit 20, and supplies power from the power reception means 20a to the illuminator 30 (FIG. 1). The illumination member 30 a is an element that is attached to the illumination surface 3 b of the blower main body 3 and constitutes the illuminator 30. In this way, power is supplied to the blower device 1 and the illuminator 30. The inner cylinder 7 corresponds to the air path dividing means of the present invention.

  The air blowing means 11 includes blades 11 a, a wind tunnel 11 b, and a motor 11 c, and a plurality of air blowing means 11 are arranged in parallel inside the air blower body 3. The air blowing means 11 sends air from the air discharge port 9 to the outside of the air blower main body 3, and in the first embodiment, it is an axial flow type air blower. The plurality of air blowing means 11 can be switched between operation and stop for each one or a plurality of air blowing means 11. Hereinafter, one or a plurality of units for switching between operation and stop of the air blowing means 11 are referred to as air blowing units. The plurality of blowing means 11 are provided for each blowing unit in each divided internal air passage 10. The air blowing means 11 may be configured to send air with an air flow excited by ion migration generated by applying a high voltage between the electrodes provided inside to discharge and so-called ion wind.

  The air direction adjusting means 13a and 13b are provided for each air blowing unit of the internal air passage 10 and adjust the air discharge direction. The wind direction adjusting means 13a is formed of, for example, a flat plate, and is provided so that the flat plate surface faces in a substantially horizontal direction. The wind direction adjusting means 13b is made of, for example, a flat plate, and is provided so that the flat plate surface faces in a substantially vertical direction.

  The dust collecting means 14 has an arc-shaped cross section, and is provided along the air intake 8 so as to occupy almost half the area of the outer periphery of the side surface of the blower body 3. The dust collecting means 14 collects dust contained in the air that has flowed into the blower main body 3. For example, the dust collecting means 14 is configured by forming a polyethylene thin thread into a 40 to 50 mesh / square inch mesh. . Thereby, since dust and insects of 0.5 mm or more are captured by the dust collecting means 14 before entering the inside of the blower main body 3, with a vacuum cleaner or the like in daily work such as indoor cleaning, It is possible to clean and remove dust and insects adhering to the dust collecting means 14. In addition, since the dust collecting means 14 is provided in the vicinity of the air intake 8, the state of collecting dust and small insects entering from the living area can be visually confirmed, and a dust cleaner or the like can be used as part of daily cleaning work. Since dust and insects captured by the dust collecting means 14 can be removed, the performance of cleaning indoor air can be maintained.

  The air cleaning means 15 has an arc-shaped cross section, and is provided along the air intake 8 so as to occupy almost half the area of the outer periphery of the side surface of the blower main body 3. In the first embodiment, the air cleaning means 15 is provided on the downstream side of the dust collecting means 14. The air cleaning means 15 has a function of adsorbing volatile organic compounds contained in the intake air and removing suspended fine particles. For example, a filter medium in which artificial enzyme is added to mixed paper obtained by mixing activated carbon with cellulose is used. In addition, the one formed into a corrugated honeycomb structure of about 230 mesh / square inch with little pressure loss or the one obtained by folding a planar filter medium made of a nonwoven fabric into a pleated structure is used. In this case, all of the air cleaning means 15 are disposable and can be exchanged into a cassette type.

  The air cleaning means 15 may be a honeycomb or corrugated substrate made of a hygroscopic material having a hygroscopic function combined with a room temperature active catalyst. As the hygroscopic material, hygroscopic ceramics based on silica gel or zeolite are used. As the normal temperature active catalyst to be combined with the hygroscopic material, a catalyst in which a noble metal and a metal oxide are combined is used. Gold, platinum, iridium, rhodium or ruthenium is used as the noble metal, and tin oxide, manganese oxide, tantalum oxide, zirconium oxide, titanium oxide, cerium oxide or the like is used as the metal oxide. Hygroscopic ceramics can be easily combined with a room temperature active catalyst, can have a long life, and can be reinforced by being incorporated into a frame. The air cleaning means 15 described above is disposable, whereas the air cleaning means 15 described later absorbs or condenses water vapor in the air on the surface even when the hygroscopic material is at a temperature of about room temperature. The odor removal function is achieved by dissolving volatile organic compounds such as water-soluble odor gas in the air in the water film. The volatile organic compound dissolved and retained in the water film of the hygroscopic material is gradually oxidized and decomposed by the normal temperature active catalyst, and the air cleaning means 15 self-regenerates. In other words, it can be used for many years without maintenance.

Here, based on the collection efficiency of the volatile organic compound and the air flow rate of the air blowing means, the effective ventilation conversion amount is calculated by the following (Equation 1).
(Formula 1) Effective ventilation conversion amount per hour = Hour air flow rate × Volatile organic compound collection efficiency The volatile organic compound collection efficiency in (Formula 1) is represented by (Formula 2).
(Equation 2) Volatile organic compound collection efficiency = (concentration C upstream of the air cleaning means−concentration Cp downstream of the air cleaning means) ÷ concentration C upstream of the air cleaning means

  In other words, when the effective ventilation conversion amount is regulated at a predetermined value, the blast air volume can be reduced if the collection efficiency of volatile organic compounds is high, and the effective ventilation conversion amount is reduced in the general ventilation of the room. If the value exceeds the required ventilation, general ventilation is not necessary, and it is not necessary to install ventilation equipment, and heating and cooling costs and equipment construction costs can be reduced.

  That is, the effective ventilation conversion amount, which is the product of the hourly blowing air volume of the blowing means 11 in the blowing device 1 and the collection efficiency of the volatile organic compounds of the air cleaning means 15, is the volume of the living room 100 in which the blowing device 1 is installed. If it is 50% or more, it can satisfy the general ventilation volume of 0.5 times or more per hour, which is required by the measures against sick house under the Building Standard Law.

  The suspended particulate detection means 16 is provided between the dust collecting means 14 and the air cleaning means 15 in the air flow direction, and detects particulates floating inside the blower body 3. The temperature detection means 17 is provided between the dust collection means 14 and the air cleaning means 15 in the air flow direction, and detects the temperature of the air. Note that only one of the suspended particulate detection means 16 and the temperature detection means 17 may be installed.

  The determination means (not shown) determines whether the concentration of the fine particles detected by the suspended fine particle detection means 16 and the temperature detected by the temperature detection means 17 exceed a predetermined threshold or a predetermined change rate. judge. An alarm means (not shown) notifies the user of an abnormal state when it is determined by the determination means that a predetermined threshold value or a predetermined change rate is exceeded. The alarm means, for example, changes the lighting state according to the determination result of the determination means and informs the user of the abnormal state, or changes the sound emitted according to the determination result of the determination means, This is a buzzer for informing the state. Here, for example, when a fire occurs indoors during air circulation, the determination means determines that the temperature detected by the temperature detection means 17 exceeds a predetermined threshold (predetermined change rate), The warning means promptly issues a warning notifying the user that a fire has occurred.

  The sterilization means 21 is provided in one air passage divided by the inner cylinder 7 and performs sterilization of the air flowing through the one air passage divided by the inner cylinder 7. The deodorizing means 22 is provided in the other air passage divided by the inner cylinder 7 and deodorizes the air flowing through the other air passage divided by the inner cylinder 7. In addition, it is good also as a structure by which only any one of the microbe elimination means 21 and the deodorizing means 22 is installed. Note that each of the internal air passages 10 divided by the inner cylinder 7 may be provided with a sterilization means 21 and a deodorization means 22 in series in the air flow direction.

The ion generating means 23 is disposed downstream of the air blowing means 11 relative to the air blowing means 11 and generates sterilization ions for removing microorganisms. For example, the ion generating means 23 collects moisture in the air on a cooling plate, supplies it to a porous electrode to which a high voltage is applied, and discharges micro charged mist of several tens of nanometers by electrostatic spraying. is there. Thereby, since the mist which does not contain ozone or the like having strong oxidizing power is released, the mist itself does not affect the health, and charged particles, active particles, and the like can remove microorganisms in the air. When the charged mist adheres to the virus, for example, 99% of the virus floating in the 10 m ³ space can be removed in 90 minutes.

Below, the effect | action of the air blower 1 is demonstrated.
When the air blowing means 11 is operated, air flows into the air blower main body 3 from the air intake 8, passes through the dust collecting means 14 and the air cleaning means 15, branches near the inner cylinder 7, and is sterilized by the sterilizing means 21 or deodorizing. Pass through means 22. The air that has passed through the sterilizing means 21 or the deodorizing means 22 is blown from the air discharge port 9 through the operating blowing means 11 among the blowing means 11 provided for each area partitioned by the inner cylinder 7. It is discharged toward the outside of the device 1.

  The blower device 1 according to Embodiment 1 includes a plurality of blower units 11 that are divided into a plurality of blower units one by one or more and that can be switched between operation and stop for each blower unit. The air passage dividing means divides the air blowing unit into air blowing units, and the area of the internal air passage 10 is narrowed from the air intake port 8 toward the air discharge port 9. For this reason, even if a part of air blowing units stops operation at the time of small air volume operation, the speed of the air discharged from the air discharge port 9 to the outside of the blower main body 3 is ensured. Therefore, the indoor air discharged from the blower main body 3 is spread to every corner of the room, thereby eliminating air stagnation and lowering the pollutant concentration, making the temperature distribution in the room uniform, blowing power and heating / cooling load Can be reduced. As described above, a plurality of blowing means 11 operable in one or a plurality of blowing units are provided, and the area of the internal air passage 10 is narrowed from the air intake port 8 toward the air discharge port 9. Therefore, deterioration of the indoor environment is suppressed.

  Further, the blower device 1 according to the first embodiment is configured such that the area of the internal air passage 10 is narrowed from the air intake port 8 toward the air discharge port 9. For this reason, the speed of the air discharged from the air discharge port 9 to the outside of the blower main body 3 is ensured. Therefore, the occurrence of a short circuit in which the air discharged from the air discharge port 9 to the outside of the blower 1 is directly sucked into the air intake port 8 is suppressed. Moreover, since the reach distance of the air discharged from the air discharge port 9 is ensured, the indoor air environment can be made uniform.

  Moreover, the air blower 1 which concerns on this Embodiment 1 becomes a structure by which the illuminator 30 is provided in the lower surface of the air blower main body 3. FIG. For this reason, the air flowing in and out from the air intake port 8 and the air discharge port 9 circulates in the circulation channel 107 and circulates the air in the entire room 100 along the ceiling surface 101, the wall surface 108, and the floor surface 109. In winter, the air circulation throughout the room prevents the air quality and thermal environment from becoming uneven without causing the residents to feel the airflow. Further, the cold draft of indoor air caused by the inflow of outside air from the air supply port 102 formed on the wall surface 108 or the heat transfer of the window surface 104 causes the warm air in the vicinity of the ceiling surface 101 to be transferred to the wall surface 108, the air supply port 102, and the window surface 104. It can be mitigated by distributing it along the line, and the occurrence of chilliness and condensation can be suppressed.

  Moreover, the air blower 1 which concerns on this Embodiment 1 is provided with the wind direction adjustment means 13a, 13b. For this reason, the discharge direction of air can be adjusted for every blowing unit of the blowing means 11.

  Moreover, the air blower 1 which concerns on this Embodiment 1 becomes a structure by which the internal air path 10 is divided | segmented into plurality and the several air blower means 11 is arrange | positioned in the divided | segmented air path. For this reason, each size of the several ventilation means 11 can be comprised small, and the air blower main body 3 can be reduced in thickness.

  Further, in the blower device 1 according to the first embodiment, the dust collecting means 14 and the air purifying means 15 occupy almost half the area of the main body side surface 3c of the blower main body 3 and are arranged over many surfaces. It has a configuration. For this reason, an air circulation area becomes large and a suction flow velocity is reduced. Therefore, the occurrence of a short circuit in which the air discharged from the air discharge port 9 to the outside of the blower 1 is directly sucked into the air intake port 8 is suppressed, the pressure loss applied to the blower unit 11 is suppressed, and the blower unit 11 Power consumption is reduced. Moreover, since the collection efficiency of the volatile organic compound in the air cleaning means 15 tends to become higher as the circulation speed is lower, the collection efficiency is reduced when the suction flow rate is reduced as in the first embodiment. Efficiency is high.

  In addition, the blower 1 according to the first embodiment includes any one of the sterilization unit 21 that performs sterilization of air and the deodorization unit 22 that performs deodorization of air for each air path divided by the inner cylinder 7. It is the arrangement which is arranged. And the air blower 1 which concerns on this Embodiment 1 becomes a structure by which the ventilation means 11 is provided in each divided | segmented internal air path 10 for every one or several ventilation units in addition to this structure. ing. With these configurations, the sterilizing means 21 and the deodorizing means 22 function by the operation of one or a plurality of air blowing units, and the pressure distribution is increased in the velocity distribution of the air flowing through the sterilizing means 21 and the deodorizing means 22. Therefore, it is possible to sterilize and deodorize efficiently.

  Further, in the blower device 1 according to the first embodiment, the blower unit 11 is constituted by a plurality of axial flow type blowers including the blades 11a, the wind tunnel 11b, and the motor 11c. For this reason, the vibration of the rotating body can be finely suppressed and dispersed. Therefore, generation | occurrence | production of the noise by the vibration of the air blower 1 is suppressed, malfunctions, such as the flicker of the illuminator 30 attached to the lower surface of the air blower 1, are suppressed, and the audio-visual environment of indoor space can be improved.

  Further, in the air blower 1 according to the first embodiment, the inner cylinder 7 includes the power supply unit 20 in which the power receiving means 20a and the attachment power feeding means 20b are disposed, and thereby the air blower 1 and the illuminator 30 are included. Power supply is performed. Since the charging parts of these electrical components are integrated, the air discharged from the air discharge port 9 circulates and is isolated from the air path flowing into the blower 1 from the air intake port 8. Therefore, it is possible to prevent fine dust and moisture contained in the air circulating in the room from accumulating on the charging unit and causing problems such as power supply tracking and short-circuiting, so that the safety of the blower device 1 is ensured and the blower device 1. And the installation work of the illuminator 30 becomes easy.

  Moreover, since the air blower main body 3 is thinned as mentioned above, the air blower 1 which concerns on this Embodiment 1 is also suppressed that the illuminator 30 provided in the lower surface of the air blower 1 protrudes indoors. . Therefore, the visual environment of the indoor space can be improved.

  Moreover, since the ventilation apparatus 1 is drive | operated inside the living room 100 which concerns on this Embodiment 1, the pollutant contained in the air in the living room 100 is removed, and the air from which the pollutant was removed circulates.

  Moreover, since the pollutant is removed by the operation of the blower 1, the living room 100 according to the first embodiment can increase the effective ventilation conversion amount, and can reduce the general ventilation amount of the increase. it can. Further, if the effective ventilation conversion amount is a value greater than the necessary ventilation amount in the general ventilation of the living room 100, the general ventilation by the general ventilation device is unnecessary, and therefore, the blower device 1 only needs to be operated. When only the blower 1 is operated, it is not necessary to install general ventilation equipment, so that heating / cooling costs and equipment construction costs can be reduced.

  As described above, the air blower 1 and the living room 100 according to the first embodiment perform energy saving of the general ventilation that allows the exhaust from the living room 100 and the air supply to the living room 100 to function constantly (24 hours). By spreading the air discharged from the inside of the main body 3 to every corner of the room, the stagnation of the air can be eliminated, the pollutant concentration can be lowered, and the temperature distribution in the room can be made uniform. Furthermore, by removing volatile organic compounds with an air purifying means, the effective ventilation conversion amount can be increased, the overall ventilation amount of the increase can be reduced, and a sick house countermeasure at the time of building renovation can be easily performed.

Then, it branches near the inner cylinder 7 and passes through the sterilizing means 21 or the deodorizing means 22. The air that has passed through the sterilizing means 21 or the deodorizing means 22 passes through the operating air blowing means 11 among the air blowing means 11 provided for each of the areas defined by the inner cylinder 7, and the air discharge ports 9 a and 9 b. To the outside of the blower 1.

In the blower device 1 according to the second embodiment, the flow passage cross-sectional area of the internal air passage 10 is narrowed from the air intake 8 toward the plurality of air blowing means 11 disposed in the internal air passage 10, and the plurality The air paths from the air blowing means 11 to the air discharge ports 9a and 9b are separated from each other.
For this reason, the speed of the air discharged from the air discharge ports 9a and 9b to the outside of the blower main body 3 is ensured, and the air discharge direction on the installation plane is separated. Therefore, the occurrence of a short circuit in which the air discharged from the air discharge ports 9a and 9b to the outside of the blower 1 is directly sucked into the air intake port 8 is suppressed, and the arrival of the air discharged from the air discharge ports 9a and 9b is reached. Since the distance is secured, the indoor air environment can be made uniform.
Furthermore, since the air discharge direction on the installation plane is separated, if the blower 1 is installed near the center of the room, the air discharged to the corner 100a (FIG. 5) of the room where air tends to stagnate is scattered. Can.

In the first and second embodiments, the outline of the blower main body 3 is described as a substantially cylindrical shape, but may be a rectangular parallelepiped or a polyhedron.
In the first and second embodiments, an example in which an axial flow type fan is used has been described. However, a radiant flow type fan such as a sirocco fan may be used.
