Description

[Technical Field]

[0001] The present invention relates to an air purifier that purifies the air by removing dust, pollen, odorous components, PM2.5, viruses, and other particles from the air. [Background technology]

[0002] Popular air purifiers include a main body that includes a dust-collecting filter section that purifies the air by removing dust in the air drawn in through an intake section by causing it to adhere to a dust-collecting filter, and an electric precipitator section that, for example, controls the flow of electricity when a dirt sensor (dust sensor or gas sensor) determines that the air is highly dirty (high dust level) to electrostatically charge the dust in the passing air and electrostatically attract the dust to a dust-collecting electrode, thereby purifying the air, and the air that has been purified by passing through this dust-collecting filter section or electric precipitator section is blown out from the outlet section by a blower. For example, such air purifiers may be configured so that the dust-collecting filter section is detachably attached to the main body, and the electric precipitator section is detachably attached upstream or downstream of the dust-collecting filter section.

[0003] Furthermore, the electric dust collecting section of such an air purifier may, for example, have a number of ionizing electrodes arranged in parallel, and a number of dust collecting electrodes arranged in parallel at intervals from each of these ionizing electrodes. When the air is heavily soiled (the dust level is high) and it is desired to increase the purification capacity, current is passed to the ionizing electrodes by controlling the flow of current through the electrode terminals which are in contact with and conductive to the voltage supply section, and a voltage is applied to each ionizing electrode as a positive electrode and each dust collecting electrode spaced apart and facing it as a negative electrode, and dust in the air passing through this is electrostatically attracted to each of the negative dust collecting electrodes and removed, thereby purifying the air.

[0004] Furthermore, in many conventional air purifiers, the intake section is located on the front, and even when located on the bottom, the intake opening is either on the front or rear of the bottom. There are also models with intake openings located around the entire bottom (four directions), as in Patent Document 1, but the strength of the bottom decreases, which reduces the rigidity of the main body, making it impossible to open a large opening, and cleaning the inside of the intake opening is difficult, resulting in poor maintainability.

[0005] As a result, there are not enough intake openings in all four directions, so if a detection unit such as a dirt sensor (dust sensor or gas sensor) is installed on the back, it will be difficult to detect dirt if the unit is installed in a position where air does not circulate easily, so the unit must be installed in a carefully selected location, which limits the freedom of layout.

[0006] Furthermore, the intake section is difficult to clean during maintenance, making it difficult to maintain. In addition, the air drawn into the main body does not flow evenly, making it difficult for the dust collector to collect dust efficiently.

[0007] Furthermore, when constructing a main body configured to take in air from the bottom, blow it to the top, and exhaust purified air from the top, it is necessary to design a layout between the intake section at the bottom and the exhaust section at the top, including a dust collection section in which a dust collection filter section and an electric dust collection section can be attached and detached, and an air blower section consisting of a blower fan and its motor section, and then incorporate these to form the main body, and then attach the exterior panels, which makes manufacturing (assembly) very difficult and results in a configuration that is poor in terms of assembly workability and mass production.

[0008] For example, in such conventional air purifiers, as shown in Patent Document 2, the main body is divided vertically and these parts are assembled one after the other, so they must be assembled by screwing from the side.In addition, various parts must be inserted from the front opening excluding the main body case, and these parts must also be assembled by screwing from the side, so assembly is very troublesome and workability is poor.

[0009] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-252512 [Patent Document 2] International Publication No. WO-2012 / 144345 Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention has identified and solved these problems. It is a configuration in which an intake section is provided at the bottom and a blowing section is provided at the top, with a dust collection section and an air blowing section between them, and this lower intake section is configured with intake openings on four sides. Dust in the air flowing from the four directions at the bottom, i.e., all around the circumference, to the upper center by the air blowing section is removed and purified in the dust collection section. This configuration not only allows for a larger area of ​​the intake opening and a larger applicable floor area, but also makes cleaning easy and maintenance excellent. Furthermore, air can easily circulate regardless of the position of a detection section such as a dirt sensor on the main body, making it easy to detect dirt and other contaminants. Also, localized air pollution can be easily detected and purified instantly. This configuration allows for greater freedom in layout when installing, and because air passes evenly through the dust collection section, dust collection is efficient and maintenance is less frequent. Furthermore, the main body is configured by stacking units in which each section is unitized, so the strength of the main body, including the bottom, is strong. It is also an object of the present invention to provide an innovative air purifier that is easy to assemble, easy to assemble, and suitable for mass production. [Means for solving the problem]

[0011] The gist of the present invention will be explained with reference to the accompanying drawings.

[0012] The air purifier is provided with a main body 1, which is made up of an intake section 2 that draws in outside air, a dust collection section 3 that purifies the air by removing dust from the air drawn in through the intake section 2, a blowing section 4 that blows out the purified air, and a blowing section 5 that creates a flow of air that is drawn in through the intake section 2 and blown out from the blowing section 4. The intake section 2 is provided at the bottom of the main body 1, and the blowing section 4 is provided at the top, so that air flows from bottom to top due to the blowing section 5. The intake section 2 at the bottom of the main body 1 is provided with intake openings 6 in four directions, front, back, left, and right, so that air that flows in from each of the intake openings 6 in the four directions flows upward and passes through the dust collection section 3, thereby being purified and discharged from the blowing section 4 at the top. The main body 1 is made up of a stacked tower unit, which is made up of stacked units 8 that constitute each section stacked successively on top of a bottom unit 7 that constitutes the intake section 2. The lower part of each of the stacking units 8 constituting the stacking tower unit is provided with a lower flange portion 11 that overlaps with the upper receiving portion of the bottom unit 7 or overlaps with an upper flange portion 10 provided at the top of another stacking unit 8 below it, and the stacking tower unit is fastened with fasteners 13 that are screwed from above into fastening holes 12 provided in the upper flange portion 10 and the lower flange portion 11, so that the stacking units 8 are stacked and fastened in sequence on top of the bottom unit 7 and assembled in a tower shape, and the upper flange portion 10 provided at the top of the stacking unit 8 is provided with an escape notch 14 that allows the escape of a tool used to fasten the fasteners 13. The present invention relates to an air purifier characterized by the above.

[0013] The bottom unit 7 is a unit that is configured as an intake section 2 in which the intake openings 6 are provided between the unit support sections 9 at the four corners, and outside air is drawn into the central space from these intake openings 6 in the four directions, and is related to the air purifier described in claim 1, characterized in that it is configured as a unit located at the bottom of the stacked tower unit that constitutes the main body section 1.

[0014] The main body 1 is also related to the air purifier described in claim 1, characterized in that an exterior panel 17 is attached to the stacked tower unit, which is formed by stacking at least a dust collection unit that constitutes the dust collection unit 3 as the stacked unit 8 and an air blower unit that constitutes the air blower unit 5 as the stacked unit 8, above the bottom unit 7 that constitutes the air intake unit 2.

[0015] An engaging protrusion 15 is provided on the lower surface of the lower flange portion 11 provided at the bottom of the stacking unit 8, and this engaging protrusion 15 is engaged with the upper flange portion 10. It is set up in The stacking unit (8) is stacked in a state where it is engaged with the positioning engagement portion (16) and is aligned. 1 The present invention relates to the air purifier described above. [Effects of the Invention]

[0016] Since the present invention is configured as described above, it has an intake section at the bottom and an outlet section at the top, with a dust collection section and an air blowing section between them, and this lower intake section has intake openings in four directions, so that dust in the air flowing from the four directions at the bottom, i.e., from all directions around the circumference, to the upper center section is removed and purified in the dust collection section. This configuration not only allows for a larger area of ​​the intake opening and a larger applicable floor area, but also makes it easy to clean and maintain. Moreover, air can easily circulate no matter where a detection section such as a dirt sensor is located on the main body, making it easy to detect dirt, and locally generated air pollution can also be detected and purified instantly. This configuration also increases the freedom of layout when installing, and because air passes evenly through the dust collection section, dust collection efficiency is good and maintenance frequency is low. Furthermore, because the main body is configured by stacking stack units in which each section is unitized, the strength of the main body, including the bottom, is strong, and it is easy to assemble, resulting in an innovative air purifier with excellent assembly workability and mass productivity.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The best mode for carrying out the present invention will now be briefly described with reference to the accompanying drawings, illustrating the operation of the present invention.

[0019] The outside air is drawn into the main body 1 from the intake section 2 by the blower section 5, and as this air passes through the dust collection section 3 of the main body 1, dust in the air is adhered to or adsorbed and removed, purified, and then discharged from the blower section 4.

[0020] Specifically, for example, the main body 1 is provided with a dust collection filter section equipped with a dust collection filter as the dust collection section 3, and an electric dust collection section is also provided as another dust collection section 3 upstream or downstream of this dust collection filter section, and the outside air is drawn in from the intake section 2 of the main body 1 by the blower section 5, and as this air passes sequentially through each dust collection section 3 (electric dust collection section and dust collection filter section), dust adheres to or is adsorbed and removed, thereby purifying the air and discharging it from the upper blow-out section 4.

[0021] That is, for example, dust in the air is captured by the dust collection filter of a dust collection filter section attached midway along the air flow and is removed, but upstream of this, an electric dust collector section that operates by controlling the flow of electricity is provided in a layered state, and the air flow rate of the blower section 5 is controlled according to the detection status of a dirt sensor (dust sensor or gas sensor), for example, and when this dust sensor detects that the dirt is severe (dust level is high), electricity is supplied to the electric dust collector section 3, which automatically operates to electrostatically electrostatically attract the dust in the air to the dust collection electrode and remove it.In this way, the purification capacity of the electric dust collector 3 can be increased as appropriate (according to the degree of dirtiness of the air), making it possible to purify the air efficiently and quickly.

[0022] In other words, the dust collecting section 3 of the present invention may consist of only this dust collecting filter section or only an electric dust collecting section, but as mentioned above, the dust collecting section 3 may be configured by stacking a dust collecting filter section and an electric dust collecting section in parallel, so that when the capacity of the dust collecting filter section is insufficient or to strengthen it, for example, air passes through both sections, and electricity is controlled constantly or as needed to operate the electric dust collecting section in addition to the dust collecting filter section, thereby increasing the purification capacity.

[0023] Furthermore, the intake section 2 at the bottom of the main body 1 of the present invention is configured with intake openings 6 provided in four directions, i.e., front, back, left and right, so that air flowing in from each of these intake openings 6 in all four directions, i.e., from all directions, flows upward and passes through the dust collection section 3, where it is purified and then discharged from the upper blow-out section 4.

[0024] Therefore, rather than simply being provided on the front or back of the main body 1, a large intake opening 6 can be arranged so that air can be taken in from all four directions, i.e., from the front, back, left, and right, i.e., from all directions. This not only allows for a larger intake opening area and a larger applicable floor area, but also makes it easy to reach into this intake opening 6 as needed to easily clean the inner bottom surface of the bottom unit 7, which is prone to getting dirty, resulting in excellent maintainability.

[0025] Furthermore, no matter where the detection unit such as the dirt sensor is located on the side or back of the main body 1, room air is drawn into the main body 1 from four directions, i.e., all around. This allows the air to circulate easily, making it easy to detect air pollution. Even if pollution occurs locally in the air, it is drawn in and purified directly, i.e., instantly, without diffusing, so the purification time is short, and therefore there is more freedom in the layout when installing.

[0026] In addition, air is drawn in from all four directions (front, back, left, right) and is purified in the dust collection section 3 above, so that the air passes through this dust collection section 3 relatively evenly, resulting in excellent purification capacity and reduced maintenance frequency for the dust collection section 3.

[0027] Furthermore, the main body 1 of the present invention is configured by stacking stacking units 8, which are units made up of various parts such as the dust collection section 3 and the air blowing section 5, on a bottom unit 7 that makes up the intake section 2 (because the main body 1 is configured as a stacking tower unit by stacking and assembling the stacking units 8 in this way), so the strength of the main body, including the bottom, is strong.In addition, the design is easy, and the stacking units 8, each assembled with various parts, can be stacked on top of each other by screwing them from above to form a stacking tower unit, so assembly work is also easy, resulting in a configuration that is excellent in terms of assembly workability and mass productivity. [Example]

[0028] Specific implementations of the present invention For example: This will be explained based on the drawings.

[0029] This embodiment comprises an intake section 2 that draws in outside air into the main body 1, a dust collection section 3 that removes dust from the air drawn in from the intake section 2 to purify the air, a blowing section 4 that blows out the purified air, and an air blowing section 5 that creates a flow of air that is drawn in from the intake section 2 and blown out from the blowing section 4.The air blowing section 5 provided in the main body 1 blows air from below to above, so that outside air is drawn into the upper center from the intake sections 2 that are provided in four directions (front, back, left, and right) of the bottom, i.e., all around the circumference, and a dust collection section 3 that removes dust in the air and purifies it is provided at the lower upstream side of the blowing section 5 of the main body 1, i.e., along the entire middle of the air passage.

[0030] Specifically, a dust collection filter section equipped with a dust collection filter is attached as the dust collection section 3 upstream (bottom) of the air blowing section 5 of the main body 1, and an electric dust collecting section is attached further upstream (bottom) of this as another dust collection section 3, and the air blowing section 5 draws in outside air from the intake section 2 of the main body 1, and as this air passes through each dust collection section 3 (electric dust collecting section and dust collecting filter section), dust adheres to or is adsorbed and removed, thereby purifying the air and discharging it from the upper blowing section 4.

[0031] That is, for example, dust in the air is captured by the dust collection filters of the dust collection filter section attached to the entire surface of the air flow path and is removed, but an electric dust collector section is attached in a layered state upstream of this, and the airflow rate of the air blower section 5 is controlled according to the detection status of a dirt sensor (dust sensor or gas sensor), for example, and when this dust sensor detects that the dirt is severe (dust level is high), the current is controlled to operate this electric dust collector section 3, which electrostatically charges the dust in the air and electrostatically attracts it to the dust collection electrode for removal, and the electric dust collector section 3 is configured to be able to increase the purification capacity as appropriate (according to the degree of dirtiness of the air).

[0032] In other words, the dust collection section 3 of this embodiment is configured so that it is layered with a dust collection filter section equipped with a dust collection filter that captures and removes dust in the air to purify the air, and an electric dust collection section (a pre-filter section is also provided upstream of the lower section) that electrostatically adsorbs and removes dust in the air to purify the air, and the air blowing section 5 is provided above and downstream of the dust collection section 3 consisting of the dust collection filter section and the electric dust collection section, and above the air blowing section 5 are provided a blowing section 4 that blows out air purified by the dust collection section 3, a control operation section 18, and the like.

[0033] More specifically, the electric dust collecting unit 3 provided as the dust collecting unit 3 in this embodiment is configured to include an ionization electrode unit 20 configured with a number of linear ionization electrodes arranged in parallel at intervals, a dust collecting electrode unit 21 configured with a number of dust collecting electrodes arranged in parallel at intervals and spaced from each of the ionization electrodes, each of which is arranged in parallel at intervals and electrostatically attracts dust in the air passing through, and electrode terminal units (contact terminal units) that bring into electrical contact with a voltage supply unit that applies voltage to each of the ionization electrodes and each of the dust collecting electrodes spaced apart from them.

[0034] Furthermore, the electrostatic precipitator 3 in this embodiment is a single combined part in which the ionization electrode unit 20 and the dust collection electrode unit 21 are slidably engaged and integrated, and is configured as a detachable unit that can be attached and removed by smoothly sliding horizontally to the unit mounting unit 23 of the main body 1 using a guide mechanism (note that guide rails 22 provided on the upper left and right sides of the ionization electrode unit 20 of the electrostatic precipitator 3 shown in the figure are part of this guide mechanism). In this embodiment, the dust collection electrode unit 21 held by this slide engagement completion positioning means can be pulled out while the ionization electrode unit 20 is fixed to the unit mounting unit 23, i.e., the dust collection electrode unit 21, which requires frequent maintenance, can be pulled out while the ionization electrode unit 20 is left fixed to the unit mounting unit 23, and further, after pulling out the dust collection electrode unit 21, the remaining ionization electrode unit 20 can be pulled out from the unit mounting unit 23 as needed by holding the pull-out knob.

[0035] The electrostatic dust collecting section 3 configured in this detachable unit is configured so that a slide engagement guide mechanism can slide freely along the length of the numerous ionization electrodes that are arranged at intervals between these ionization electrodes, and the ionization electrode section 20 and the dust collecting electrode section 21 can be slidably separated into two parts (two units). When the dust collecting electrode section 21 (drawer unit part) slides away from the ionization electrode section 20 (main unit part) to form two parts, the numerous dust collecting electrodes of the dust collecting electrode section 21 become exposed, making it easy to clean and remove electrostatically adsorbed dust and improving maintainability.

[0036] In addition, the intake section 2 at the bottom of the main body 1 in this embodiment is configured to have large intake openings 6 in each of the four directions, i.e., front, back, left, and right, and the air flowing in from each of the intake openings 6 provided in these four directions, i.e., in the circumferential direction, flows upward and passes evenly through the dust collection section 3, thereby being purified and discharged from the blowing section 4 at the top.

[0037] The main body 1 of this embodiment is configured as a stacked tower unit formed by stacking stacked units 8 that constitute each part on top of a bottom unit 7 that constitutes the intake section 2, and an exterior panel 17 is attached to each side of this stacked tower unit.

[0038] Specifically, the bottom unit 7 has a rectangular shape in plan view, with the upper opening covered by the pre-filter section at the bottom of the dust collecting section 3 above it, and is configured as a unit with a flat inner bottom and a U-shaped cross section. It also has unit support sections 9 at its four corners, with one or more large cutouts or openings provided across the entire width between them to form the intake openings 6. Outside air is drawn in by the upward air blown by the blower section 5 from the large intake openings 6 of the bottom unit 7, which are arranged in four directions, i.e., all around the circumference. In other words, the unit (bottom unit) is configured as a unit that constitutes the intake section 2, where outside air is drawn into the central space on the flat bottom from the intake openings 6 in the four directions and introduced into the dust collecting section 3 above.

[0039] In other words, the stacked tower unit is formed by stacking the stacked units 8 that make up each part on top of this bottom unit 7, and this bottom unit 7 is located at the bottom of the stacked tower unit and is configured as a unit that makes up the intake section 2.

[0040] In this way, the main body 1 is configured by stacking the stacked units 8 on top of the bottom unit 7 that constitutes the intake section 2, but in this embodiment, the stacked units 8 are sequentially stacked on top of the bottom unit 7 as stacked units 8, including an electric dust collector unit that constitutes the electric dust collector of the dust collector section 3, a dust collection filter unit that constitutes the dust collection filter of another dust collector section 3, a control unit that incorporates various components such as a control board that also incorporates sensors, and an air blower unit (that incorporates a blower fan, drive source, etc.) that constitutes the air blower section 5, to form the stacked tower unit, and the main body 1 is constructed by attaching the top panel equipped with the upper blowing section 4 and control operation unit 18 and other surface panels as exterior panels 17 to this stacked tower unit that forms the skeleton of the main body.

[0041] Therefore, in this embodiment, as mentioned above, the intake openings 6 of the intake section 2 are not simply provided on the front or back, but large intake openings 6 are provided in at least four locations in four directions so that air can be taken in from all four directions, i.e., from the front, back, left and right, i.e., from all directions. This not only makes it possible to increase the intake opening area and the applicable floor area, but also makes it easy to put your hand in through the intake openings 6 on any of the four directions and easily clean the bottom surface of the bottom unit 7, which is prone to getting dirty, resulting in excellent maintainability.

[0042] Furthermore, no matter where the detection unit such as the dirt sensor is located on the side or back of the main body 1, the air in the room is drawn into the main body 1 from four directions, i.e., all around. This allows the air in the room to circulate easily, making it easy to detect air pollution. Even if pollution occurs locally in the air, it is drawn in and purified directly, i.e., instantly, without diffusing, so the purification time is short, and therefore there is more freedom in the layout when installing.

[0043] In addition, air is drawn in from all four directions (front, back, left, right) and is purified in the dust collection section 3 above, so that the air passes through this dust collection section 3 relatively evenly, resulting in excellent purification capacity and reduced maintenance frequency for the dust collection section 3.

[0044] Furthermore, the main body 1 is configured by stacking stacking units 8, which are units made up of various parts such as the dust collection unit 3 and the air blowing unit 5, one on top of the other on the bottom unit 7 that makes up the intake unit 2 (because the main body 1 is configured as a stacking tower unit in this way by stacking and assembling the stacking units 8), which makes the main body, including the bottom, very strong.In addition, the design is simple, and the stacking units 8, each assembled with various parts, can be stacked one on top of the other by fastening them with screws from above, which makes assembly easy and results in a configuration that is excellent in terms of ease of assembly and mass production.

[0045] Furthermore, this stacking unit 8 that constitutes each part is configured so that the flanges and other connecting parts are sealed when stacked, and the outside air is efficiently drawn in through the intake part 2 by the blower part 5, passes through the dust collection part 3, and is discharged from the blowing part 4. In other words, the configuration prevents a decrease in the air volume and prevents air from being taken in from anywhere other than the intake part 2.

[0046] To explain further, in this embodiment, the lower part of the stacking unit 8 that constitutes the stacking tower unit is provided with a lower flange portion 11 that overlaps with the upper receiving portion of the bottom unit 7 or with an upper flange portion 10 provided at the top of another stacking unit 8 below it.

[0047] That is, the stacking tower unit is configured with reinforcing ribs extending vertically between these flanges and between the upper and lower flanges, thereby increasing the unit strength and allowing for stable stacking. Specifically, a plurality of stacking units 8 are sequentially stacked on the bottom unit 7 with the lower flange 11 overlapping the upper flange 10 formed to protrude horizontally on the left and right, and fasteners 13 (e.g., screws) are screwed from above into fastening holes 12 (screw holes or through holes) provided in the upper receiving portion, the upper flange 10, and the lower flange 11, thereby assembling them into a tower shape.

[0048] In this embodiment, the upper flange portion 10 provided on the upper portion of the stacking unit 8 has a recess for a tool (a screwdriver) for fastening the fastener 13. Relief notch The configuration is set up with 14.

[0049] Specifically, the upper flange portion 10 has a through hole, and the lower flange portion 11 has a screw hole in a downwardly protruding threaded tube as the fastening hole 12, into which a screw is screwed as a fastener 13 to be fixed in place with the screws. This makes it easy to stack, the fastening position is easy to see, and since the fastening work is done from above, the fastening work can be done very stably, improving work efficiency.

[0050] Furthermore, each section is constructed as a unit, and after assembling the parts for each section, the lower flange section 11 is stacked stably on top of the upper flange section 10 which protrudes horizontally upward, and most of the assembly can be done by fastening (screw fastening) from above, making assembly very efficient and easy.

[0051] In this embodiment, when performing this fastening operation (for example, fastening a screw from directly above with a screwdriver), it is fine if there is no upper flange portion 10 above, but if there is an upper flange portion 10, the screwdriver will escape into this upper flange portion 10. Gasu The escape Notch Specifically, it is formed in a semicircular notch that allows for operation with a screwdriver.

[0052] This prevents the upper flange 10 from getting in the way. Relief notch By placing a screwdriver at 14, it becomes possible to fasten the screws with the screwdriver from directly above, which makes the assembly work (fastening each screw) even easier.

[0053] In this embodiment, an engagement protrusion 15 is provided on the lower surface of the lower flange portion 11 provided at the bottom of the stacking unit 8, and this engagement protrusion 15 engages with the upper flange portion 1 to 0 The stacking units 8 are configured so that they can be stacked in an aligned state by engaging with the provided alignment engaging portions 16.

[0054] Specifically, an engaging protrusion 15 protruding downward is provided near the fastening hole 12 of the lower flange portion 11, and by engaging this, the lower flange portion 11 can be positioned and face-to-face assembled on the upper flange portion 10. Furthermore, if an attempt is made to stack the stacking unit 8 in the wrong direction, the engaging protrusion 15 cannot be aligned and engaged, preventing face-to-face assembly, so that the misassembly can be detected, i.e., prevented.

[0055] The positioning engagement portion 16 with which the engagement protrusion 15 engages is Relief notch Even in this case, if you try to attach it in the opposite direction (180 degrees horizontally inverted), the engaging protrusions 15 will not engage and you will realize that you have misassembled it. If you stack them in the correct direction, all of the engaging protrusions 15 will share the alignment engaging portion 16. Relief notch14 and can be stacked. That is, in this embodiment, the flange portion is provided with a positioning concave-convex engaging structure to prevent incorrect assembly.

[0056] Furthermore, the upper flange 10 of the fastening hole and the overlapping lower flange 11 may be provided with a concave-convex engaging structure 19 for concave-convex engagement in addition to the alignment concave-convex engaging structure, which further increases the unit rigidity, increases the stacking strength, and provides a sealing function to prevent air intake in addition to the alignment function to prevent incorrect assembly. In this embodiment, this concave-convex engaging structure 19 is also used in part of the fastening portion.

[0057] Furthermore, in this embodiment, the lower flange portion 11 of the stacking unit 8 is superimposed on the upper end portion 10 of the side wall as the upper flange portion 10 of the bottom unit 7, and then each flange portion 10, 11 of the stacking unit 8 is superimposed on top of this in turn, and stacked while being fastened with screws in order to construct a stacked tower unit with a four-way air intake section 2 using the bottom unit 7, thereby forming the main body 1. Therefore, assembly is easy and the unit is rigid. Furthermore, the main body 1 is formed by attaching thin exterior panels 17, which take into consideration design and functionality, so that they abut against the stacked tower units that form the framework of the main body 1. Therefore, the strength requirements for the exterior panels 17 are low and so they can be thin, making it easy to improve design and functionality. Furthermore, even if the exterior panels 17 are thin, they can be attached to the side edges of the upper flange portion 10 or the lower flange portion 11, for example, to prevent deflection.
