  In recent years, there has been a demand for higher performance and longer life of dust collection filters, and further suppression of power consumption in consideration of the global environment.

  The problem with the above conventional example is that there is a trade-off relationship between the collection efficiency or collection life of the dust collection filter and the pressure loss, and all the performances of the pressure loss and collection efficiency and collection life of the dust collection filter are considered. It was difficult to satisfy.

  That is, in the conventional dust collection filter, when an electrostatic filter with low pressure loss, low air resistance and high collection efficiency is used, the collection life is as short as 5 years or less. On the other hand, when a glass filter that enables a long life of 5 years or longer is used, a glass filter medium with a high pressure loss is required to ensure the same collection efficiency as that of an electrostatic filter. It was.

  Accordingly, an object of the present invention is to realize suppression of power consumption by a dust collection filter having a high collection efficiency and a long life and a low pressure loss.

In order to achieve this object, the present invention comprises a main body case having an intake port and an exhaust port, and an air cleaning means provided in the main body case. The air cleaning means includes a glass filter portion and an electrostatic filter. The glass filter portion and the electrostatic filter portion are formed in two layers, and the glass filter portion and the electrostatic filter portion are connected in parallel, and the air that has been sucked into the main body case from the air inlet is the glass filter portion or the air cleaner Blowing means for blowing air to the exhaust port through only one of the electrostatic filter portions is provided on the downstream side of the air cleaning means , and the intake ports are provided on the main body case and on both side surfaces. And a second air intake port provided in the lower front portion of the main body case. The electrostatic filter is provided in the vicinity of the second air intake port, The glass filter section at the top of the filter portion are those that having a rectangular shape of the air cleaning unit linked, thereby, it is to achieve the intended purpose.

As described above, the present invention includes a main body case having an intake port and an exhaust port, and an air cleaning means provided in the main body case. The air cleaning means has two layers of a glass filter portion and an electrostatic filter portion. The glass filter part and the electrostatic filter part are formed in parallel, and the glass filter part or the electrostatic filter part which is the air purifying means for the air sucked into the main body case from the intake port. Blower means for blowing air to the exhaust port through only one of the two is provided on the downstream side of the air cleaning means , and the intake port includes first intake ports provided on the main body case and on both side surfaces. A second air inlet provided in the lower front of the main body case, the electrostatic filter is provided in the vicinity of the second air inlet, The glass filter portion parts are those that having a rectangular shape of the air cleaning unit coupled with high collection efficiency and long life, the more low pressure loss of the air cleaning device, to realize the suppression of the power consumption It is something that can be done.

That is, the glass filter part that is the air cleaning means and the electrostatic filter part are connected in parallel, and either the glass filter part that is the air cleaning means or the electrostatic filter part is the air sucked into the main body case from the air inlet. The air supply means for supplying air to the exhaust port through the air cleaner is provided on the downstream side of the air cleaning means, and the air intake port is provided at the first air intake port provided on the upper and both side surfaces of the main body case, and at the lower front portion of the main body case.

As for the characteristics of each filter, the glass filter part exhibits the effect of extending the life, and the electrostatic filter part exhibits the effect of reducing the pressure loss. The surface wind speed on the low-pressure-loss electrostatic filter side is relatively high, so that the surface wind speed on the glass filter side is relatively slow and the collection efficiency of the glass filter is improved and the pressure loss can be reduced. . On the other hand, since the electrostatic filter has a low pressure loss and a high collection efficiency, it can maintain a low pressure loss and a high collection efficiency as compared with the glass filter even if the surface wind speed is relatively fast. With these actions, it is possible to reduce power consumption by long-life, high collection efficiency, and air cleaning means with low pressure loss, and intake ports are provided on the top and both sides of the main body case.

  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIGS. 1 to 5, an air cleaning device 1 with a humidifying function of this embodiment includes a main body case 4 having an intake port 2 and an exhaust port 3, and an air cleaning means 5 provided in the main body case 4. And humidifying means 6 are provided. By the air blowing means 7 provided on the downstream side of the humidifying means 6, the air sucked into the main body case 4 from the air intake port 2 is blown to the exhaust port 3 through the air cleaning means 5 and the humidifying means 6 in this order. is there.

  The humidifying means 6 is formed of a moisture releasing portion 8, a water supply portion 9, and a rotating means 10 that rotates the moisture releasing portion 8. The moisture releasing portion 8 is formed of a disc-shaped humidifying filter 11 and a humidifying filter frame 12 fixed to the humidifying filter 11 and rotatably provided. The humidifying filter frame 12 has a water supply portion 13 on the outer peripheral portion. Provided, and a rotation shaft portion 14 is provided at the center. The water supply portion 9 is formed by a substantially bowl-shaped water tank 15 provided at the lower portion of the humidifying filter 11 and a water tank 16 for supplying a constant amount of water to the water tank 15.

  The air cleaning and humidifying operation in the above configuration will be described.

  First, the air sucked into the main body case 4 from the air inlet 2 is subjected to an air cleaning process in which dust and the like are collected by passing through the air cleaning means 5. The air subjected to the air cleaning process is sent to the humidifying means 6. In the humidifying means 6, the humidifying filter frame 12 is provided so that a part of the water supply unit 13 and the humidifying filter 11 of the humidifying filter frame 12 are always immersed in the water supplied to the water tank 15. It is rotated by the rotating means 10. A certain amount of water is supplied from the water tank 16 to the water tank 15 by the water supply unit 13 of the humidifying filter frame 12 by the rotation, and the water is pumped up and supplied to the upper part of the humidifying filter 11 so that the humidifying filter 11 contains moisture. Then, the air sucked into the main body case 4 from the air inlet 2 by the air blowing means 7 is sent to the humidifying filter 11 through the air cleaning means 5 to humidify the air, and the humidified air is blown to the air outlet 3. It is.

  The feature in this embodiment resides in the air cleaning means 5. The air cleaning means 5 is formed of two layers of a glass filter 17 portion and an electrostatic filter 18 portion, and the glass filter 17 portion and the electrostatic filter 18 portion are connected in parallel. That is, the air sucked into the main body case 4 from the air inlet 2 by the air blowing means 7 is blown to the air outlet 3 through either the glass filter 17 portion or the electrostatic filter 18 portion which is the air cleaning means 5. Is.

  That is, the glass filter 17 portion that is the air cleaning means 5 and the electrostatic filter 18 portion are connected in parallel, and the air that has been sucked into the main body case 4 from the air inlet 2 or the glass filter 17 portion that is the air cleaning means 5 or the static air filter 5 portion. The air is blown to the exhaust port 3 through one of the electric filter 18 parts, and the characteristics of each filter are such that the glass filter 17 part exhibits the effect of extending the life and the electrostatic filter 18 part is low. Demonstrates the effect of pressure loss. The surface wind speed on the side of the low-pressure-loss electrostatic filter 18 is relatively high, so that the surface wind speed on the side of the glass filter 17 is relatively slow and the collection efficiency of the glass filter 17 is improved and the pressure loss is reduced. Can be lowered. On the other hand, since the electrostatic filter 18 has a low pressure loss and a high collection efficiency, it can maintain a lower pressure loss and a higher collection efficiency than the glass filter 17 even if the surface wind speed is relatively fast. Due to these actions, it is possible to achieve a long life of 5 years or more and high collection efficiency, and furthermore, it is possible to suppress power consumption by means of an air cleaning means with low pressure loss.

  The glass filter 17 in the glass filter 17 portion is obtained by pleating a sheet made of glass fiber. The electrostatic filter 18 in the electrostatic filter 18 portion is obtained by pleating a chargeable sheet made of resin fibers. The characteristics of each filter are that the glass filter 17 part has a surface wind speed of 0.9 m / s, a pressure loss of around 50 Pa, a collection efficiency of about 95% (0.3 μm or more), and the electrostatic filter 18 part has the same surface wind speed. The pressure loss is around 25 Pa and the collection efficiency is about 97% (0.3 μm or more), and two filters are combined and used as one air cleaning means 5. The upper side of the air cleaning means 5 is configured as a glass filter 17, and the lower side is configured as an electrostatic filter 18, and the area ratio is set to glass: electrostatic = 3: 1 to 2: 1. Thereby, the surface wind speed on the electrostatic filter 18 side becomes faster than 0.9 m / s, and the surface wind speed on the glass filter 17 side becomes slower than 0.9 m / s. As a result, the pressure loss of the glass filter 17 becomes lower than 50 Pa, and the collection efficiency becomes higher than 95%. On the other hand, the pressure loss of the electrostatic filter 18 is higher than 25 Pa but lower than 50 Pa, and the collection efficiency is lower than 97% but can be higher than 95%. A collection life of 10 years or more can be secured, and a long life can be realized. That is, the air purifying means 5 having a long life and high collection efficiency and further having a low pressure loss can be realized.

  The performance and the composition ratio of the glass filter 17 and the electrostatic filter 18 may not be as described above.

  Further, the air inlet 2 is formed by a first air inlet 2 a provided on the top and both side surfaces of the main body case 4, and a second air inlet 2 b provided at the lower front of the main body case 4. An electrostatic filter 18 portion is provided on the downstream side in the vicinity of the second air inlet 2b, and a glass filter 17 portion is connected to the upper portion of the electrostatic filter 18 portion to form a rectangular air cleaning means 5. . That is, since the surface wind speed on the electrostatic filter 18 side is relatively high, the amount of air sucked into the main body case 4 from the second air inlet 2b is increased, and about 30 cm above the floor among the dust present in the air. It is possible to efficiently collect house dust dust existing in the area. On the other hand, fine dust and odorous components such as tobacco tend to float above the room, and are collected by the glass filter 17 that sucks in from the first air inlet 2a and is resistant to tobacco dust. Thereby, it becomes possible to exhibit durability also with respect to tobacco.

  Although the electrostatic filter 18 is on the lower side, it may be on the upper side in some cases.

  The upper and lower layers are not limited to the upper and lower sides such as the left and right sides.

  Moreover, since the electrostatic filter 18 part is in a position facing the second air inlet 2b, the air sucked from the second air inlet 2b easily flows in a straight line into the electrostatic filter 18 part. Thereby, the house dust dust which exists about about 30 cm on the floor among the dust which exists in the air can be collected efficiently.

  Moreover, since the glass filter 17 part of the glass filter 17 and the electrostatic filter 18 part of the electrostatic filter 18 part are folded in a pleat shape, the surface area of each becomes large, and a low pressure loss, a high collection efficiency, and a long length. Life can be extended. In addition, if a bead 19 made of hot melt is provided to maintain the shape of the pleats, it is possible to suppress structural pressure loss due to shape change.

  Although the electrostatic filter 18 has a pleated shape, the non-woven fabric 21 may not have a pleated shape.

  The bead 19 made of hot melt may not be provided.

  Further, since the glass filter 17 in the glass filter 17 portion and the electrostatic filter 18 in the electrostatic filter 18 portion are folded into a pleat shape and the fold is in the horizontal direction 23, the boundary portion 24 of the two-layer filter can be easily joined. . Moreover, since the width dimension of a filter medium can be made the same, it becomes easy to manage in processing and manufacturing.

  Although the crease is in the horizontal direction 23, it may be in the vertical direction 25. Needless to say, the performance in this case has the same effect. In such a case, joining can be facilitated by fixing both ends of the pleats with a frame material and bonding the frames together.

  The fold line may be a mixture of the horizontal direction 23 and the vertical direction 25.

  Further, since the pitch of the glass filter 17 in the glass filter 17 portion folded in a pleat shape is smaller than the pitch in which the electrostatic filter 18 in the electrostatic filter 18 portion is folded in a pleat shape, the glass filter 17 and the electrostatic filter 18 Identification becomes easy.

  In addition, although the pitch of the glass filter 17 is made small, if the electrostatic filter 18 is similarly made small, it will be possible to further reduce the pressure loss and increase the collection efficiency.

  Further, by handling the periphery of the electrostatic filter 18 and the glass filter 17 with a paper frame 20 to form an integral and separable rectangular air cleaning means 5, handling and maintenance are improved.

  In addition, although it is supposed that it adheres with the paper frame 20, you may use things other than paper, or it is good also as an integral type by a lunch box system using a box-shaped resin frame.

  The upstream side of the air cleaning means 5 is provided with an anti-bacterial agent-attached non-woven fabric 21 and a pre-filter 22 to provide an additional function, and the coarse dust is collected by the pre-filter 22 and the vacuum cleaner By performing maintenance, etc., it is possible to suppress an increase in pressure loss due to clogging.

  Only one of the nonwoven fabric 21 and the prefilter 22 may be used.

  In addition to the antibacterial agent, it may be an additive effective against mold, anti-virus, and anti-allergen.

  Although the antibacterial agent is attached to the nonwoven fabric, it may be attached to the prefilter 22, the glass filter 17, or the electrostatic filter 18.

  Further, since the humidifying means 6 is provided between the air cleaning means 5 and the blower means 7, clean air can be directly applied to the humidifying filter 11, and the cleanliness of the humidified air can be improved. At the same time, if the humidifying filter 11 is installed immediately before the suction port 26 of the air blowing means 7, it is possible to pass almost the entire air volume to the humidifying filter 11, and the humidifying function can be improved.

  Further, by providing the second intake port 2b, the humidifying unit 6 and the suction port 26 of the blower unit 7 in a substantially straight line, the path from the second intake port 2b to the suction port 26 of the blower unit 7 is also in a substantially straight line. Therefore, the ventilation resistance in this route is reduced, the pressure loss in the machine of the main body is reduced, and the proportion of the amount of air that flows linearly to the humidifying filter 11 is increased, so that the air passes uniformly to the humidifying filter 11. By this, it becomes possible to humidify efficiently.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and an air cleaning means provided in the main body case. The air cleaning means has two layers of a glass filter portion and an electrostatic filter portion. The glass filter part and the electrostatic filter part are formed in parallel, and the glass filter part or the electrostatic filter part which is the air purifying means for the air sucked into the main body case from the intake port. A blowing means for blowing air to either the exhaust port or the exhaust port is provided on the downstream side of the air cleaning means, with high collection efficiency and long life, and further by a low pressure loss air cleaning means, It is possible to reduce power consumption.

  That is, the glass filter part that is the air cleaning means and the electrostatic filter part are connected in parallel, and either the glass filter part that is the air cleaning means or the electrostatic filter part is the air sucked into the main body case from the air inlet. The characteristics of each filter are such that the glass filter part exhibits the effect of extending the life and the electrostatic filter part exhibits the effect of reducing the pressure loss. The surface wind speed on the low-pressure-loss electrostatic filter side is relatively high, so that the surface wind speed on the glass filter side is relatively slow and the collection efficiency of the glass filter is improved and the pressure loss can be reduced. . On the other hand, since the electrostatic filter has a low pressure loss and a high collection efficiency, it can maintain a low pressure loss and a high collection efficiency as compared with the glass filter even if the surface wind speed is relatively fast. Due to these actions, it is possible to suppress power consumption by air purifying means having a long life and high collection efficiency and further reducing pressure loss.

  Therefore, it is expected to be utilized as an air purifier with a humidifying function for home use or office use.
