As shown in FIG. 1, the air cleaner 1 according to Embodiment 1 of the present invention includes a base part 100 and a duct part 200. The base portion 100 has a shape formed by two substantially rectangular parallelepipeds stacked one above the other. More specifically, the base portion 100 has a shape formed by superimposing a relatively small substantially rectangular parallelepiped in a plan view on a relatively large substantially rectangular parallelepiped in a plan view. Therefore, a stepped step is formed on the side surface of the base portion 100.

That is, the outer shape of the base part 100 has an upper surface 121, a first side surface 122, a connection surface 123 and a second side surface 124, and a bottom surface not shown in FIG. 1. The first side surface 122 is provided to extend downward from the outer end of the upper surface 121. Here, the first side surface 122 is provided substantially perpendicular to the upper surface 121. The connection surface 123 is provided so as to extend from the lower end of the first side surface 122 to the outside of the base portion 100. Here, the connection surface 123 is provided substantially perpendicular to the first side surface 122. The second side surface 124 is provided to extend downward from the outer end of the connection surface 123. Here, the second side surface 124 is provided substantially perpendicular to the connection surface 123.

In this way, the connection surface 123 connects the lower end of the first side surface 122 and the upper end of the second side surface 124. Here, the connection surface 123 is a substantially horizontal surface, but may be inclined. Here, although the first side surface 122 and the second side surface 124 are substantially vertical surfaces, one or both of these side surfaces may be inclined. Further, the height dimension of the second side surface 124 may be made extremely small by providing a plate-like member below the first side surface 122.

An air outlet 110 that is a first opening is formed on one side surface of the base portion 100. More specifically, the air outlet 110 that is the first opening is disposed on the first side surface 122 of the side surfaces of the base portion 100.

A duct part 200 is attached to the upper surface 121 of the base part 100. The duct part 200 has a hollow cylindrical shape. Here, the duct part 200 is hollow and substantially cylindrical. In addition, the shape of the duct part 200 is not restricted to this, For example, a hollow prismatic shape etc. may be sufficient.

The duct part 200 is provided so as to stand upward from the upper surface of the base part 100. That is, the longitudinal direction of the duct part 200 is set up perpendicular to the upper surface of the base part 100. A suction port 201 that is a second opening is formed on the side surface of the duct part 200. The suction port 201 is arranged over the longitudinal direction of the duct part 200. The suction port 201 is provided with a suction port cover in which a mesh-like prefilter is provided on a lattice-shaped frame.

The closure body 202 is attached to the upper end of the duct part 200. One end in the longitudinal direction of the hollow duct portion 200 is closed by the closing body 202. On the other hand, the base portion 100 described above is connected to the other longitudinal end of the duct portion 200.

Referring to FIG. 2, the description of the configuration of the air cleaner 1 will be continued. A ventilation path 203 is formed inside the duct portion 200. The ventilation path 203 communicates with the suction port 201 formed in the duct part 200. In addition, a filter (not shown) that is an air cleaning means is attached to the inside of the duct portion 200. This filter is, for example, a HEPA (High Efficiency Particulate Air) filter. The filter is disposed between the suction port 201 and the ventilation path 203 inside the duct unit 200.

A blower fan 300 is accommodated in the space within the base portion 100. In addition, a motor 400 is also housed inside the base portion 100. The motor 400 is for rotating the blower fan 300.

Furthermore, the description will be continued with reference to FIG. FIG. 3 is an enlarged view of portion A in FIG. A space in the base portion 100 in which the blower fan 300 is accommodated communicates with the ventilation path 203 of the duct portion 200. Further, the space in which the blower fan 300 is accommodated communicates with the blower passage 101 formed in the base portion 100. The air passage 101 communicates with the air outlet 110. In this way, the air inlet 201 of the duct part 200 communicates with the air outlet 110 via the air passage 203, the blower fan 300 and the air passage 101.

Here, as described above, a step is formed on the side surface of the base portion 100, and the first side surface 122, the connection surface 123, and the second side surface 124 are formed in this step portion from the top. Yes. The air outlet 110 is provided on the first side surface 122. Therefore, the connection surface 123 extends substantially horizontally below the outside of the air outlet 110. Moreover, the 2nd side surface 124 exists in the outermost part of the base part 100, and the blower outlet 110 in the 1st side surface 122 exists in the base part 100 inside the 2nd side surface 124 in planar view.

Also, the air passage 101 is inclined so as to go upward as it goes from the inside to the outside of the base part 100. In other words, the air passage 101 is inclined so as to go upward from the portion of the blower fan 300 toward the air outlet 110. Therefore, the airflow blown from the blower outlet 300 through the blower passage 101 from the blower outlet 110 is guided by the inclined surface of the blower passage 101 and becomes obliquely upward from the horizontal.

FIG. 4 schematically shows a state in which the air purifier 1 configured as described above is installed close to the wall surface. The base part 100 of the air cleaner 1 is placed on a floor surface 501 that is an installation surface. A wall surface 502 extends vertically upward from the floor surface 501.

The position where the air cleaner 1 can be brought closest to the wall surface 502 is the position where the outer end of the base portion 100 contacts the wall surface 502. At this time, a case is considered where the air outlet 110 which is the first opening faces the wall surface 502 side. In this case, as described above, on the side where the air outlet 110 is located, the outermost side of the base portion 100 is the second side surface 124. Therefore, when the air cleaner 1 is brought closest to the wall surface 502, the second side surface 124 comes into contact with the wall surface 502.

In this state, as described above, the air outlet 110 on the first side surface 122 is located inside the base portion 100 from the second side surface 124, so that a gap is formed between the air outlet 110 and the wall surface 502. Can do. Therefore, even if the air purifier 1 is installed close to the wall surface 502, it is possible to prevent the outlet 110 from being blocked by the wall surface 502.

At this time, since there is a connection surface 123 on the lower side outside the air outlet 110, the air flow that has come out of the air outlet 110 and hits the wall surface 502 is directed upward. Therefore, it is possible to prevent the airflow coming out of the air outlet 110 and hitting the wall surface 502 from flying up dust on the floor surface 501.

In addition, since the air flow that exits from the outlet 110 due to the inclination of the air passage 101 has an upward velocity component, the air stream that exits from the outlet 110 and hits the wall surface 502 is more smoothly directed upward. It is possible to reduce the airflow loss.

In addition, in the above, the case where the blower outlet 110 was provided in the one side of the base part 100 was demonstrated. In such a case, the step, that is, the first side surface 122, the connection surface 123, and the second side surface 124 need only be provided at least on the side where the air outlet 110 is provided.

On the other hand, as schematically shown in FIG. 5, the air outlet 110 may be provided on a plurality of side surfaces of the base portion 100, for example, all four side surfaces. In this case, the steps, that is, the first side surface 122, the connection surface 123, and the second side surface 124 may be provided on all sides (here, all four sides) where the air outlet 110 is provided.

Further, it is sufficient that at least a part of the air passage 101 is inclined so that an air flow is blown obliquely upward from the horizontal from the air outlet 110, and in particular, a portion close to the air outlet 110 is preferably inclined.

In addition, in the above, the case where the 1st opening formed in the base part 100 was made into the blower outlet 110 and the 2nd opening formed in the duct part 200 was made into the suction inlet 201 was demonstrated. However, the functions and roles of the first opening and the second opening are not limited thereto. That is, conversely to the above case, the first opening formed in the base portion 100 may be used as the suction port, and the second opening formed in the duct portion 200 may be used as the air outlet. Even if it is reversed in this way, it is possible to obtain the advantageous effects as described above, such as preventing the suction port as the first opening from being blocked by the wall surface.

The air cleaner configured as described above is mounted on an installation surface such as the floor surface 501, for example, and a base portion 100 in which a blower outlet 110 as a first opening is formed on a side surface, and an upper surface of the base portion 100. And a hollow cylindrical duct portion 200 which is provided upright from 121 and has a suction port 201 formed as a second opening on a side surface thereof. The base portion 100 includes a first side surface 122, a connection surface 123 extending from the lower end of the first side surface 122 to the outside of the base portion 100, a second side surface 124 extending downward from the outer end of the connection surface 123, have. And the blower outlet 110 which is a 1st opening is arrange | positioned at the 1st side 122. FIG.

For this reason, even when the air purifier 1 is installed near the wall, the first opening (air outlet 110) through which air flows can be prevented from being blocked by the wall surface, and air can be stably blown. It is. In addition, when a fan is mounted inside, the first opening (air outlet 110) through which air flows is closed, so that air does not flow and there is no risk of temperature rise.

Embodiment 2. FIG.
6 and 7 relate to Embodiment 2 of the present invention. FIG. 6 is a cross-sectional view schematically showing a state in which the air cleaner is installed adjacent to the wall surface, and FIG. 7 is an arrow B in FIG. It is an arrow view seen from the direction of.

In the first embodiment described above, a step is provided on the side surface where the first opening (air outlet) of the base portion is formed. On the other hand, Embodiment 2 demonstrated here is made to incline the side surface in which the 1st opening (air outlet) of a base part is formed instead of a level | step difference.

That is, as shown in FIG. 6, at least one of the side surfaces of the base portion 100 is an inclined side surface 125. The inclined side surface 125 is inclined so as to be higher toward the inner side of the base part 100 and lower toward the outer side of the base part 100. And the blower outlet 110 which is 1st opening is formed in this inclination side surface 125. As shown in FIG.

The base part 100 of the air cleaner 1 is mounted on the floor surface 501 which is an installation surface. A wall surface 502 extends vertically upward from the floor surface 501. Here, FIG. 7 shows the inclined side surface 125 viewed from the direction indicated by the arrow B in FIG. 7 can also be said to be the inclined side surface 125 and the outlet 110 on the projection plane parallel to the floor surface 501 that is the installation surface.

As shown in FIG. 7, since the inclined side surface 125 is inclined so as to become higher toward the inner side of the base portion 100, the blower outlet lower edge 112 on the projection plane is lower than the blower outlet upper edge 111. It is closer to the outside of the part 100.

Here, consider a case where the air cleaner 1 is installed closest to the wall surface 502 so that the air outlet 110 which is the first opening faces the wall surface 502 side. In this case, as shown in FIG. 6, when the outer end of the base portion 100 comes into contact with the wall surface 502, the air outlet upper edge 111 is located inside the base portion 100 with respect to the air outlet lower edge 112. On the upper edge 111 side, a gap can always be formed between the outlet 110 and the wall surface 502. Therefore, even if the air purifier 1 is installed close to the wall surface 502, it is possible to prevent the outlet 110 from being blocked by the wall surface 502.

Note that, instead of the inclined side surface 125, the side surface is, for example, a curved surface, so that the outlet lower edge 112 is closer to the outside of the base portion 100 than the outlet upper edge 111 on the projection plane. Also good.
Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

The air purifier configured as described above is placed on an installation surface such as the floor surface 501, for example, and the base unit 100 in which the air outlet 110 that is the first opening is formed on the side surface, and the base unit 100. A hollow cylindrical duct portion provided upright from the upper surface 121 and having a second opening (suction port) formed on a side surface thereof. And the blower outlet 110 which is the 1st opening has the lower edge (blower outlet lower edge 112) of the 1st opening on the projection surface parallel to the said installation surface. 111) and closer to the outer side of the base part 100.

For this reason, similarly to Embodiment 1, even if the air cleaner 1 is installed near the wall, the air outlet 110 that is the first opening formed on the side surface of the base portion 100 is blocked by the wall surface. Can be prevented and air can be blown stably. In addition, when the side surface on which the air outlet 110 that is the first opening is formed is inclined, the size of the gap that can be secured at least between the wall surface and the first opening can be adjusted by adjusting the angle of the inclination. It is also possible to adjust easily. With respect to other points as well, the same effects as in the first embodiment can be obtained.

The present invention can be used for an air cleaner in which an opening serving as a blow-out port or a suction port is formed on a side surface of a base portion placed on an installation surface such as a floor surface.
