Description

  The present invention relates to an air purifier that discharges air from a discharge port after purifying outside air sucked from an intake port provided in a main body case through a filter.

  The air purifier has a blower and a filter inside the main body case, and sucks outside air from the air inlet provided in the main body case by driving the blower and passes it through the filter to remove dust contained in the outside air or smell. The components are deodorized and purified, and the purified outside air is discharged from the discharge port. Generally, the discharge port is provided on the upper surface of the main body case, and the purified air is discharged from the upper surface of the air cleaner. It is. With such a configuration, since the purified air is released only from one direction, the room air is not easily circulated efficiently, and it takes time to purify the room air uniformly.

Therefore, there is an air purifier that discharges purified air from the top and left and right sides of the air purifier to improve the flow of air to every corner of the room and purify the entire room. Are known. (For example, refer to Patent Document 1).
JP 2006-136808 A

  The air cleaner described in Patent Document 1 requires two blowers, an upper blower for discharging purified air from above and a lower blower for discharging from the left and right directions, which increases costs. In addition, since the blowers are arranged above and below, there is a problem that the height of the main body is high and the size is increased.

  The object of the present invention is to avoid the increase in size and cost of the main body, and to discharge the purified air from the left, right, and upper three directions, thereby making it possible to purify the entire room uniformly by improving the air flow in the room. An air purifier is provided.

  In order to solve the above problems, the present invention drives a blower including a sirocco fan to purify the outside air sucked into the main body case through the filter through the filter, and the purified air enters the fan casing of the blower. An air cleaner that sucks and discharges outside the main body case through a discharge port provided in the fan casing, and is provided with a partition plate that partitions the fan casing of the blower back and forth in the axial direction of the blower. Either one of the fan casings is provided with two outlets on the left and right sides to discharge the purified air from the left and right sides of the main body case, and the other fan casing is provided with an outlet on the upper side for purification. Air is discharged from the upper surface of the main body case.

  Specifically, two left and right discharge ports are formed in the fan casing ahead of the partition plate, and an upper discharge port is formed in the fan casing behind the partition plate.

  According to the present invention, the fan casing of one blower is divided into front and rear, and purified air is discharged from one fan casing from both the left and right directions of the main body case, and the purified air is discharged from the other fan casing by the main case. Since it is released from above, it can release purified air from three directions with one blower, and it is inexpensive and does not increase the size of the main body. Can be purified.

  Since the air purifier is often used by being placed near the wall of the room, if the purified air is discharged in the left-right direction from the front fan casing and the purified air is discharged upward from the rear fan casing, Then, the purified air can be discharged along the air and the room air can be circulated more easily, and the room air can be purified more efficiently.

  Hereinafter, the present invention will be described with reference to FIGS. 1 is a longitudinal cross-sectional view of the air cleaner, FIG. 2 is a cross-sectional view taken along line AA in FIG. 1, FIG. 3 is a cross-sectional view taken along line BB in FIG. 1, and FIG. It is sectional drawing based on CC line.

  The main body case 1 of the air purifier includes a rear case 2 that forms the bottom part, the rear face, the left and right side surfaces, and the rear part of the upper surface, a rear cover 3 that forms the left and right side parts and the front part of the upper surface, and a front cover 4 that forms the front part. An outline is formed. The inside of the main body case 1 is divided forward and backward by a partition plate 5. A blower 6 is disposed in the rear space partitioned by the partition plate 5. The blower 6 includes a motor 7 and a sirocco fan 8 driven by the motor. The motor 7 is attached to the partition plate 5. A number of communication holes 9 are formed around the motor 7 of the partition plate 5 so as to communicate the front and rear of the partition plate 5.

  A filter 10 is disposed in the front space partitioned by the partition plate 5. The filter 10 includes a pre-filter 11 having a coarse mesh, a main filter 12 that captures fine dust, and a deodorizing filter 13 made of activated carbon particles that adsorb odorous components. From the windward side, the pre-filter 11 and the main filter 12 are arranged. The deodorizing filter 13 is arranged in this order.

  Inlet portions 14 and 14 (see FIG. 2) are provided in front portions (rear cover 3) on the left and right side surfaces of the main body case 1, respectively. In FIG. 2, the height of the intake ports 14 and 14 does not appear, but the height of the intake ports 14 and 14 is substantially the same as the height of the filter 10. A lattice-like louver 15 is attached to the intake ports 14 and 14. The intake ports 14 and 14 communicate with the space between the pre-filter 11 and the front cover 4, that is, communicate with the windward side of the filter 10.

  In the rear space partitioned by the partition plate 5, a blower 6 is disposed and a fan casing 16 surrounding the sirocco fan 8 is formed. The fan casing 16 is partitioned forward and backward in the axial direction of the sirocco fan 8 by a partition plate 3 a formed integrally with the rear cover 3. Specifically, as shown in FIGS. 1 and 2, the fan casing 16 is divided forward and backward so that each blade of the sirocco fan 8 is divided into two in the axial direction.

  The fan casing 16a on the front side of the fan casing 16 partitioned by the partition plate 3a is formed by spiral ribs 3b and 3b protruding integrally from the partition plate 3a, the partition plate 5 and the partition plate 3a. As shown in FIG. 2, two discharge ports 17 and 17 are provided at both left and right ends thereof. The left and right discharge ports 17 and 17 are connected to discharge ports 18 and 18 that are opened on the left and right side surfaces of the rear case 2. Each discharge port 18 is provided with a lattice-shaped air guide 19.

  A fan casing 16b on the rear side of the fan casing 16 partitioned by the partition plate 3a is formed by spiral ribs 2b protruding integrally from the rear case 2, the partition plate 3a and the rear case 2, and FIG. As shown in FIG. 4, one discharge port 20 is provided at the upper end. The upper discharge port 20 is connected to a discharge port 21 opened on the upper surface of the rear case 2. A lattice-shaped air guide 22 formed integrally with the rear case 2 is provided at the discharge port 21.

  In such a configuration, when the blower 6 is driven, outside air is sucked into the main body case 1 from the left and right intake ports 14, 14, and the sucked outside air is, as shown by an arrow D in FIG. 12, dust and odor components are removed and purified through the deodorizing filter 13, and the purified air is guided to the fan casing 16 through the communication hole 9.

  The fan casing 16 is divided into front and rear, and the purified air guided to the front fan casing 16a is sent from the left and right discharge ports 17 and 17 to the air guides 19 and 19, as indicated by an arrow E in FIGS. It is discharged from the left and right side surfaces of the main body case 1 through the discharge ports 18 and 18 to the outside of the machine. On the other hand, the purified air guided to the rear fan casing 16b is discharged from the upper surface of the main body case 1 through the air guide 22 and the discharge port 21 from the upper discharge port 20 as shown by the arrow F in FIGS. Released outside the machine.

  Since the air purified in this way is discharged from the three directions of the left and right side surfaces and the top surface of the main body case, the stagnation of the air in the room is reduced and the air flows well to every corner of the room, The entire room can be purified evenly. Then, one air blower 6 can discharge purified air from three directions, and it is cheaper and the main body does not become larger than the conventional one using two air blowers.

  Here, the left and right discharge ports 17 and 17 and the upper discharge port 20 may be provided in either one of the front and rear fan casings 16a and 16b, respectively. However, as in the illustrated embodiment, the front fan casings are provided. If the left and right discharge ports 17 and 17 are provided in 16a and the upper discharge port 20 is provided in the rear fan casing 16b, the rear fan casing 16b is used in an air cleaner that is often used by being placed near the wall of the room. From the discharge port 20, the purified air can be discharged along the wall, which makes it easier for the room air to circulate and more efficiently cleans the room air.

  In the above embodiment, the inlets 14 and 14 for taking outside air into the main body case 1 are provided on the left and right side surfaces of the main body case 1, but instead of being provided on the left and right side surfaces, they may be provided on the front cover 4. If the front cover 4 is provided, there is less flow path resistance and more air can be sucked. If air is sucked from the front of the main body case 1 of the air purifier and purified air is discharged from the left and right and top surfaces, the air flow in the room becomes smoother and circulates more efficiently. It is advantageous to purify the air.
