Description

[Technical Field]

[0001] The present invention relates to a cabinet fan. [Background technology]

[0002] Conventionally, cooling fans have been installed in station premises (for example, subway premises) such as station platforms and passageways. Unlike small household fans, these cooling fans are often large-scale devices. As an example, Patent Document 1 (JP 2024-004846 A) discloses a housing-type cooling fan with an air outlet on the front side and a water-absorbing member for cooling inside. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-004846 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, there has been a demand for a housing-type electric fan (hereinafter referred to as a "cabinet fan") that does not have an air cooling structure such as the water-absorbing member described above. However, such cabinet fans are usually installed along a wall or in a corner, and no structure that can ensure a large amount of airflow even in such cases has been known. [Means for solving the problem]

[0005] Therefore, the present invention has been made in consideration of the above circumstances, and has as its object to provide a cabinet fan that can ensure a large amount of airflow even when installed along a wall or in a corner.

[0006] The present invention solves the above problems by the solutions described below.

[0007] The cabinet fan of the present invention comprises a vertically long housing, an air outlet located at an upper position on the front of the housing, a first intake port located at a lower position on the front of the housing, and a fan located inside the housing behind the air outlet.

[0008] This allows air to be drawn in from a lower position on the front of the housing and blown out from an upper position on the front, so a large amount of air can be blown out even when the cabinet fan is installed along a wall (i.e., with the back close to the wall) or in a corner (i.e., with the back and at least one side close to the wall).

[0009] Preferably, the housing further includes a filter separating the first intake port from the fan, the filter being provided at an angle that slopes downward from the front to the back of the housing and being removable from the front of the housing. This prevents the filter from being pushed back and increases the effective area of ​​the filter, thereby preventing clogging of the filter.

[0010] It is also preferable that the cabinet fan further includes a second intake port provided on the bottom surface of the housing and a support member that supports the housing so that it is raised above the installation surface, thereby ensuring an even greater intake volume even when the cabinet fan is installed in the above-mentioned location.

[0011] Furthermore, it is preferable to further provide a power switch above the first suction port, which makes it difficult to turn the power on and off, thereby realizing a tamper-proof function.

[0012] Furthermore, it is preferable that a power cord be provided on either the left or right side of the housing, so that power can be secured even when the cabinet fan is installed against a wall. [Effects of the Invention]

[0013] According to the present invention, it is possible to provide a cabinet fan that can ensure a large amount of airflow even when installed along a wall or in a corner. [Brief explanation of the drawings]

[0015] The cabinet fan 100 according to the embodiment will be described in detail below with reference to the drawings. FIG. 1 is a front view of the cabinet fan 100 according to the embodiment of the present invention. FIG. 2 is a perspective view of the cabinet fan 100 according to the embodiment of the present invention from the upper left rear, illustrating the interior of the cabinet fan 100 excluding the back panel 26 and left panel 16. FIG. 3 is a bottom view of the cabinet fan 100 according to the embodiment of the present invention. FIG. 4 is a right side view of the cabinet fan 100 according to the embodiment of the present invention. Furthermore, throughout the drawings illustrating the embodiment, components having the same functions are designated by the same reference numerals, and repeated description of such components may be omitted. Furthermore, for the sake of convenience, the cabinet fan 100 according to the embodiment includes a rectangular parallelepiped housing 10 having panels on each side. However, the cabinet fan 100 and its components according to the embodiment are not limited to these specific orientations.

[0016] The overall configuration of the cabinet fan 100 in this embodiment will be described. As shown in Figures 1 to 4, the cabinet fan 100 includes a tall, vertically elongated housing 10, an air outlet 22a provided at an upper position on the front side of the housing 10, a first intake port 12bb provided at a lower position on the front side of the housing 10, and a fan 30 provided inside the housing 10 behind the air outlet 22a.

[0017] The housing 10 is made of, for example, a metal material (such as steel) and is configured as a hexahedral housing with a front panel 12, a right panel 14, a left panel 16, a top panel 18, a bottom panel 20, and a back panel 26.

[0018] The front plate 12 has a first front plate 12a to which an air grille 22 is attached, and a second front plate 12b in which a plurality of first intake slits 12ba are formed.

[0019] The air grille 22 is a lattice-like member that is attached to a substantially square hole formed in the first front panel 12a and is arranged in the up-down, left-right directions, and functions as an air outlet from the fan 30. The direction of the fins of the air outlet 22a is not particularly limited, but since the fan 30 is disposed at a high position as described below, it is preferable that the left-right grille be formed so as to be inclined downward and forward.

[0020] Additionally, a switch cover 12aa and a predetermined power switch 12ab are provided on the first front panel 12a above the ventilation grille 22. More specifically, the power switch 12ab is located inside the front panel 12 (first front panel 12a) and does not protrude from the surface. This prevents the power switch 12ab from being caught when the cabinet fan 100 is moved or when passersby pass nearby. The power switch 12ab has, for example, weak, medium, strong, and off functions, but is not limited thereto and can be modified as appropriate depending on the purpose. The power switch 12ab may have not only a switch structure but also a lever structure, etc. Providing the power switch 12ab at such a high position prevents tampering by passersby, such as children, when the cabinet fan 100 is installed in a train station, for example.

[0021] The first suction slits 12ba are formed directly on the second front panel 12b and function as suction ports for the fan 30. There are no particular restrictions on the opening direction of each first suction slit 12ba, but since the fan 30 is disposed at a high position as described above, it is preferable that the suction slits be formed with an inclination downward and forward. This makes it possible to achieve high suction efficiency and prevent the intrusion of foreign matter such as dust during storage.

[0022] The first intake slit 12ba may be provided as a separate member from the second front plate 12b using a lattice-like member (not shown).

[0023] The fan 30 is provided behind the air outlet 22a inside the housing 10. Specifically, the fan 30 is connected to a drive source (rotary motor) 36 attached to a pair of drive source support beams 32, 34 that connect the right side plate 14 and the left side plate 16.

[0024] 2, the inside of the housing 10 is partitioned by a filter 38. More specifically, the filter 38 is provided at a position separating the first intake port 12bb from the fan 30. This makes it possible to prevent dust from being blown through the air outlet 22a.

[0025] More specifically, the filter 38 is disposed at an angle that slopes downward from the front to the rear of the housing 10 and is insertable and removable from the front of the housing 10. That is, in the cabinet fan 100, the access cover 24 is attached between the first front panel 12a and the second front panel 12b. With the access cover 24 open, the filter 38 can be inserted into an insertion hole (not shown). The insertion hole slopes downward from the front to the rear. This arrangement of the filter 38 allows the filter 38 to be removed without moving the cabinet fan 100, facilitating cleaning and other operations. Furthermore, the downward slope of the filter 38 prevents the filter 38 from being pushed back. Furthermore, the effective area of ​​the filter 38 is larger than when the filter 38 is disposed horizontally, which reduces dust and other particles from entering the holes of the filter 38 and prevents clogging of the filter 38.

[0026] As shown in Fig. 3, the bottom panel 20 forming the bottom surface of the housing 10 has a plurality of second intake slits 20a formed therein, which serve as second intake ports 20b. The cabinet fan 100 also has a support member 40 that supports the housing 10 above the installation surface. Specifically, the bottom panel 20 is provided with four casters 40 that are placed on the installation surface. This allows the cabinet fan 100 to take in a larger amount of air and increase the amount of air blown, even when the cabinet fan 100 is installed on a wall or in a corner.

[0027] The second suction slit 20a may be provided as a separate member from the bottom plate 20 using a lattice-like member (not shown).

[0028] The cabinet fan 100 in this embodiment is provided with a power cord 42 on the right side plate 14. More specifically, the power cord 42 is inserted through a through-hole formed in the right side plate 14 and extends to the outside of the housing 10. The right side plate 14 is also provided with a cord support portion 44 around which the power cord 42 can be wound. This allows the cabinet fan 100 to be installed with the back plate 26 abutting against a wall surface. The power cord 42 and cord support portion 44 may also be provided on the left side plate 16 (not shown).

[0029] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the scope of the present invention. For example, although the housing 10 is provided as a rectangular parallelepiped having a certain height, the housing 10 may be wider and multiple fans 30 may be provided inside.
