Disclosure of Invention

Technical problem to be solved by the invention

However, when the wind flowing through the airflow path is supplied to a place distant from the louvers without hitting the louvers, the wind supplied to the place distant from the louvers is not guided by the louvers. As a result, there is a fear that: when the air is discharged from the outlet, the air direction that is not guided by the louvers is discharged from a direction that deviates from a desired direction (a direction according to the rotation angle of the louvers).

The invention aims to provide a flow regulating member and an air supply device which can restrain air from being discharged from a desired direction when air is discharged from an air outlet.

Means for solving the problems

According to the first aspect of the present application, the flow rectification member can be attached to the air passage leading to the outlet of the air blowing device. The flow regulating member includes a main body and a guide portion. The main body is formed with a hole for passing wind. The guide portion is provided in the hole portion and guides the wind passing through the hole portion in a predetermined direction. The guide portion has a first wall portion and a second wall portion. The first wall portion and the second wall portion have heights in a first direction, which is a direction in which wind passes. The first wall portion has a dimension in the first direction different from a dimension in the first direction of the second wall portion.

According to a second aspect of the present application, an air blowing device includes the rectifying member and a housing. The air outlet is formed in the frame. The guide portion is disposed inside the housing such that the air outlet is located on one side of the first direction with respect to the guide portion.

Effects of the invention

According to the flow rectification member and the air blowing device of the present invention, when air is discharged from the air outlet, it is possible to suppress discharge in a direction in which the direction of the air deviates from a desired direction.

Detailed Description

Embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals, and description thereof will not be repeated.

An air cleaner 100 according to the present embodiment of the present invention will be described with reference to fig. 1 and 2. Fig. 1 is a side view of an air cleaner 100 according to the present embodiment of the present invention. Fig. 2 is a sectional view of the air cleaner 100.

The air cleaner 100 is an example of the air blowing device of the present invention. The air blowing device introduces air from the outside of the air blowing device into the air blowing device, processes the introduced air, and discharges the processed air to the outside of the air blowing device. The processing treatment includes at least one of a treatment of purifying air, a treatment of supplying ions to air, a treatment of dehumidifying air, and a treatment of humidifying air, for example.

As shown in fig. 1 and 2, the air cleaner 100 includes a housing 1. The frame 1 is a hollow member. The frame 1 is made of, for example, resin.

The frame 1 includes a first frame 10 and a second frame 20. The second housing 20 is detachably attached to the first housing 10. The second frame body 20 is positioned outside the first frame body 10. By attaching the second housing 20 to the first housing 10, a part of the first housing 10 is covered with the second housing 20. The first housing 10 and the second housing 20 may be an integral component.

The housing 1 further includes a grip 3. The grip 3 has a shape in which a part of the outer surface of the housing 1 is recessed. The user grips the grip 3 and carries the air cleaner 100.

An air inlet A is formed in the housing 1. The air inlet a communicates the inside M of the housing 1 with the outside. The air inlet a is formed in the lower portion 12 of the housing 1.

Hereinafter, in a state where the air cleaner 100 is installed, the front-rear direction, the left-right direction, and the up-down direction are defined with the direction in which the air inlet a faces forward. The front-rear direction is an example of the second direction of the present invention. The front side is an example of one side in the second direction of the present invention. The left-right direction is an example of the third direction of the present invention. The vertical direction is an example of the first direction of the present invention. The upper side is an example of one side in the first direction of the present invention.

The housing 1 also forms an outlet B. The outlet B communicates the inside M of the housing 1 with the outside. The outlet B is formed in the upper portion 11 of the housing 1. The outlet B opens forward.

Air cleaner 100 further includes light emitting unit 4, cleaning unit 5, and air blowing unit 6.

The light emitting section 4, the purifying section 5, and the air blowing section 6 are disposed inside the housing 1.

The light emitting unit 4 irradiates light toward the purifying unit 5. The light emitting unit 4 includes a light source such as an LED.

The purifying unit 5 purifies air. The purification unit 5 is disposed above the light emitting unit 4. The purification unit 5 includes, for example, a photocatalytic filter. The photocatalyst included in the photocatalytic filter generates a catalytic action by being irradiated with light from the light emitting portion 4. As a result, when the air passes through the photocatalytic filter of the purification unit 5, the odor component in the air is decomposed. The odor component is, for example, ammonia gas, methyl mercaptan, trimethylamine, and/or nonenal, and the like.

The purification unit 5 may include a physical adsorption type filter and/or a chemical adsorption type filter, and the odor component may be adsorbed by the physical adsorption type filter and/or the chemical adsorption type filter. In the case where the photocatalytic filter is not used, the air cleaner 100 may not include the light emitting portion 4.

In the present embodiment, the purifying unit 5 reduces odor components in the air as a first example of the purification of the air. However, the present invention is not limited thereto. The purifying part 5 may reduce dust in the air as a second example of the purification of the air. In this case, the purifying unit 5 includes, for example, a HEPA filter.

An air passage N is formed in the interior M of the housing 1. In the present embodiment, the air passage N extends in the vertical direction. The air passage N communicates with the air inlet a and the air outlet B. The air passage N is provided with a cleaner 5 and a blower 6.

The air blowing unit 6 generates air (air flow). The blower 6 includes, for example, a fan and a drive source for rotating the fan. The drive source includes a motor, for example.

The air cleaner 100 further includes an ion supply unit 7. The ion supply unit 7 is disposed in the interior M of the housing 1. The ion supplier 7 is disposed in the air passage N. The ion supply unit 7 is disposed downstream of the air supply unit 6. The ion supplier 7 supplies ions to the air flowing in the air passage N. The ions include at least one of positive ions and negative ions.

The air cleaner 100 further includes a rectifying member 8 and louvers 9. The rectifying member 8 and the louver 9 are disposed in the air passage N.

The flow rectification member 8 guides the air sent from the air blowing unit 6. The flow rectification member 8 can be attached to the air passage N. The rectifying member 8 is disposed in the interior M of the housing 1 and fixed to the interior M of the housing 1. The rectifying member 8 is fixed to the inside M of the housing 1 by being fastened to the inside M of the housing 1 by a fixing member such as a screw and/or being engaged with an engagement portion formed in the housing 1. The flow regulating member 8 is fixed to the inside M of the housing 1, and is attached to the air passage N. The rectifying member 8 is disposed downstream of the ion supply unit 7. The rectifying member 8 is disposed at a fixed position with respect to the housing 1. In a state where the flow regulating member 8 is attached to the air cleaner 100 (air passage N), the outlet B opens toward the front side. The front side is an example of one side in the second direction of the present invention.

The louvers 9 guide the wind flowing from the rectifying member 8. The louver 9 is disposed downstream of the rectifying member 8. The louver 9 is disposed upstream of the outlet B. The louver 9 has a shape in which a plate-like member is bent. The louver 9 is disposed immediately before the outlet B in the air passage N.

The louver 9 is rotatably mounted in the interior M of the housing 1. The louver 9 is supported rotatably with respect to the housing 1.

An example of the mounting structure of the louver 9 to the housing 1 will be described.

The air cleaner 100 includes a rotary shaft 15. The rotating shaft 15 is attached to the housing 1 and supported by the housing 1.

The louver 9 includes a distal end portion 9a, a proximal end portion 9b, and a guide surface 9 c. The front end portion 9a is located closer to the outlet B than the base end portion 9B. The front end portion 9a faces the outlet B. A rotary shaft 15 is inserted through the base end 9b of the louver 9.

The front end 9a of the louver 9 rotates about the rotation shaft 15. Specifically, the front end 9a of the louver 9 rotates up and down about the rotation shaft 15. The rotation angle of the louver 9 with respect to the housing 1 is changed by the rotation of the louver 9.

By changing the rotation angle of the louver 9 with respect to the housing 1, the discharge direction H of the air discharged from the air outlet B is changed. Specifically, the inclination angle θ of the discharge direction H with respect to the vertical direction of the predetermined direction X is changed by changing the rotation angle of the louver 9 with respect to the housing 1. As a result, the air is discharged from the outlet B in a direction corresponding to the rotation angle of the louver 9. In other words, the louver 9 defines the discharge direction H of the air discharged from the air outlet B as a direction corresponding to the rotation angle of the louver 9.

The predetermined direction X indicates a direction in which the air outlet B faces. Specifically, the predetermined direction X represents a direction parallel to the horizontal plane and perpendicular to the axial direction of the rotary shaft 15 of the louver 9, among the directions from the inside M of the housing 1 to the outside of the housing 1 through the outlet B. In the present embodiment, the axial direction of the rotary shaft 15 of the louver 9 is the left-right direction. In the present embodiment, the predetermined direction X is a forward direction.

The louver 9 includes a guide surface 9 c. The guide surface 9c is a downward surface of the louver 9. The wind reaching the louver 9 flows along the guide surface 9 c. As a result, the air is discharged from the air outlet B in the direction along the guide surface 9 c.

The rotation angle of the louver 9 with respect to the housing 1 may be changed by the user. In this case, the user holds the louver 9 and rotates it. The rotation angle of the louver 9 with respect to the housing 1 may be changed by the air cleaner 100. In this case, the air cleaner 100 includes a rotation drive source such as a motor, and rotates the louvers 9 by the rotation drive source.

The air cleaner 100 further includes a storage unit S1 and a control unit S2.

The storage unit S1 includes a main storage device (e.g., a semiconductor Memory) such as a ROM (Read Only Memory) and a RAM (Random access Memory), and may further include an auxiliary storage device (e.g., a hard disk drive). The main storage device and/or the auxiliary storage device stores various computer programs executed by the control section S2.

The control Unit S2 includes processors such as a CPU (Central Processing Unit) and an MPU (MicroProcessing Unit). The control unit S2 controls each element of the air cleaner 100.

The flow of air passing through the air passage N will be described with reference to fig. 2.

As shown in fig. 2, when the air blowing unit 6 is operated, air flows from the outside of the housing 1 into the inside M of the housing 1 through the air inlet a. The air flowing into the inside M of the housing 1 flows through the inside M of the housing 1 in the order of the purifying part 5 and the ion supplying part 7. The wind flowing through the purifying part 5 and the ion supplying part 7 is purified when passing through the purifying part 5, and is supplied with ions when passing through the ion supplying part 7. The wind that has passed through the purifying section 5 and the ion supply section 7 passes through the flow rectifying member 8, and is then discharged from the outlet B in a direction corresponding to the rotation angle of the louvers 9. As a result, the wind supplied with the ions together with the purified air is discharged from the outlet B. In the present embodiment, the operation of the blower 6 means that a motor as a drive source of the blower 6 rotates a fan.

The air purifier 100 need not include both the purifying part 5 and the ion supplying part 7, and may include at least one of the purifying part 5 and the ion supplying part 7.

Next, referring to fig. 2 to 7, the rectifying member 8 will be described. Fig. 3 is a perspective view of the rectifying member 8. Fig. 4 is a plan view of the rectifying member 8. Fig. 5 is a sectional view of the rectifying member 8. Fig. 6 is a diagram showing a state where wind passes through the rectifying member 8. Fig. 7 is a perspective view of the air outlet B as viewed from the front of the housing 1.

As shown in fig. 2 to 5, the rectifying member 8 includes a main body 81. The main body 81 is a main structure of the rectifying member 8. The main body 81 is made of, for example, resin. The main body 81 is fixed to the inside M of the housing 1.

The main body 81 has a hole 82. The hole 82 penetrates the body 81 in the vertical direction. The hole portion 82 communicates upstream and downstream of the flow rectification member 8. The hole 82 has a shape in which one side of a rectangle is curved in a substantially arc shape, for example, when viewed from above. In the present embodiment, the front portion of the hole 82 is formed in a substantially circular arc shape. The shape of the hole 82 is not limited to the shape of the present embodiment. The air passage N is present in the hole 82. The outlet B is disposed in front of the hole 82 when viewed from above.

The hole 82 has a first edge 82a, a second edge 82b, a third edge 82c, and a fourth edge 82 d. The first, second, third, and

fourth edge portions

82a, 82b, 82c, 82d are portions that constitute a frame forming a space of the hole portion 82. The first, second, third, and

fourth edge portions

82a, 82b, 82c, 82d are annularly connected in the order of the first, second, third, fourth, and

first edge portions

82a, 82b, 82c, 82d, 82 a. The first edge portion 82a and the third edge portion 82c are arranged at a distance from each other in the front-rear direction and face each other in the front-rear direction. The second edge portion 82b and the fourth edge portion 82d are arranged at a distance from each other in the left-right direction and face each other in the left-right direction.

The flow rectification member 8 further includes a first rib 83 and a second rib 84. The first ribs 83 and the second ribs 84 guide air in a predetermined direction. The predetermined direction is, for example, a direction toward the louver 9. The first rib 83 and the second rib 84 are examples of the guide portion of the present invention. The first rib 83 is an example of the first wall portion of the present invention. The second rib 84 is an example of the second wall portion of the present invention.

Each of the first rib 83 and the second rib 84 is a substantially plate-like member having an elongated shape. The first rib 83 and the second rib 84 are each formed of, for example, resin. The first rib 83 and the second rib 84 are fixed to the inside M of the housing 1. The first rib 83 and the second rib 84 are disposed in the air passage N, respectively. The first rib 83 and the second rib 84 are disposed downstream of the air blowing unit 6 and upstream of the air outlet B, respectively.

The first rib 83 and the second rib 84 are disposed to face the louver 9. The louver 9 is disposed above the first rib 83 and the second rib 84. The first rib 83 intersects the second rib 84.

The first rib 83 has a long shape extending in the left-right direction. The first rib 83 is curved forward in a substantially circular arc shape and extends in the left-right direction.

The first rib 83 may be formed in a substantially linear shape without being bent. In this case, the first rib 83 has a shape extending substantially linearly in the left-right direction, for example.

The first rib 83 is erected in the hole 82.

The first rib 83 is connected to the second edge 82b and the fourth edge 82d and is erected in the hole 82, or both ends of the first rib 83 are connected to the third edge 82c and are erected in the hole 82.

The first rib 83 is provided in plurality. In the present embodiment, five first ribs 83 are provided. The adjacent first ribs 83 of the plurality of first ribs 83 are arranged at intervals from each other in the front-rear direction. The plurality of first ribs 83 are arranged substantially parallel to each other and aligned in the front-rear direction. The number of the first ribs 83 is not particularly limited.

The plurality of first ribs 83 include a rib 83a, a rib 83b, a rib 83c, a rib 83d, and a rib 83 e. Among the plurality of first ribs 83, ribs 83a to 83c are connected to the second edge 82b and the fourth edge 82d and are bridged in the hole 82. Of the plurality of first ribs 83, the ribs 83d and 83e are connected to the third edge 82c at both ends of the ribs 83d and 83e, respectively, and are erected in the hole 82.

Further, the first rib 83 may be bridged to the hole 82 with both ends of the first rib 83 connected to the first edge 82 a.

The second rib portion 84 has an elongated shape that is long in the front-rear direction. The second rib 84 has a shape extending substantially linearly in the front-rear direction. Further, the second rib 84 may have a curved shape.

The second rib 84 is bridged to the hole 82.

The second rib 84 is connected to the first rim 82a and the third rim 82c and extends through the hole 82.

The second rib portion 84 is provided in plurality. In the present embodiment, eight second ribs 84 are provided. The adjacent second ribs 84 of the plurality of second ribs 84 are arranged at intervals in the left-right direction. The plurality of second ribs 84 are arranged substantially parallel to each other and aligned in the left-right direction. The number of the second ribs 84 is not particularly limited.

The plurality of first ribs 83 and the plurality of second ribs 84 are arranged in a grid shape by crossing each other. Hole 82 is partitioned by a plurality of first ribs 83 and a plurality of second ribs 84, and is thereby divided into a plurality of partition holes 821.

The first rib 83 and the second rib 84 are bridged over the hole 82, so that foreign matter can be prevented from entering the inside M of the housing 1 through the hole 82.

As shown in fig. 5, the air sent from the air supply unit 6 passes through the plurality of spacer holes 821 when passing through the rectifying member 8 (the first ribs 83 and the second ribs 84). The air passing through the flow rectification member 8 (the partition hole 821) is directed toward the outlet B via the louver 9.

The first rib 83 and the second rib 84 guide the wind fed from the air feeder 6 so that the wind fed from the air feeder 6 is directed toward the louver 9. In the present embodiment, the first ribs 83 and the second ribs 84 cause the wind to follow the first ribs 83 and the second ribs 84, respectively, thereby adjusting the flow of the wind fed from the blowing section 6 so that the wind is directed toward the louvers 9. Therefore, the air fed from the air blowing unit 6 is prevented from being fed to a place away from the louver 9. As a result, when the air is discharged from the air outlet B, the air can be prevented from being discharged in a direction deviating from a desired direction (a direction according to the rotation angle of the louver 9).

The shapes of the first rib 83 and the second rib 84 will be described with reference to fig. 5.

As shown in fig. 5, in the vertical direction, the upper end 831 of the first rib 83 is located above the upper end 841 of the second rib 84. In the vertical position, the lower end 832 of the first rib 83 is located at substantially the same height as the lower end 842 of the second rib 84. The vertical dimension d1 of the first rib 83 is larger than the vertical dimension d2 of the second rib 84 (d1 > d 2).

The flow of wind passing through the rectifying member 8 will be described with reference to fig. 6. Fig. 6 is a schematic view showing the flow of wind passing through the rectifying member 8.

As shown in fig. 6, the air fed from the air feeder 6 (see fig. 2) flows upward and passes through the spacer hole 821. When the wind passes through the partition hole 821, the wind is attracted to the first rib 83 and the second rib 84, particularly, the first rib 83, by the coanda effect. This is because upper end 831 of first rib 83 is located above upper end 841 of second rib 84 in the vertical direction.

When wind is sucked by the first ribs 83, the wind passing through the space hole 821 easily flows in the forward direction or the backward direction. As a result, wind side leakage can be suppressed. The wind-side leakage indicates that the wind flows in a direction extending to the left and right with respect to the wind discharge direction H defined by the louvers 9 (see fig. 2).

If upper end 841 of second rib 84 is located above upper end 831 of first rib 83, the wind passing through spacer hole 821 is sucked into second rib 84. As a result, wind tends to flow in the left or right direction, and thus wind side leakage may occur. Therefore, in the present embodiment, upper end 831 of first rib 83 is arranged above upper end 841 of second rib 84, so that when wind passes through spacer hole 821, wind is sucked into first rib 83 in region E on the downstream side of spacer hole 821, thereby suppressing wind-side leakage.

Further, since the flow straightening member 8 can suppress the wind side leakage, the wind can be efficiently supplied from the outlet B to the blowing point of the wind by the louver 9, and the supply amount of the wind from the outlet B to the blowing point can be increased. As a result, the wind containing the ions generated by the ion supply unit 7 (see fig. 2) can be efficiently supplied to the blowout point, and the concentration of the ions supplied to the blowout point can be increased.

Further, by using the flow rectification member 8, even if the shape of the outlet B is not devised, the air side leakage can be suppressed by the flow rectification member 8. As a result, the degree of freedom in designing the shape of the air outlet B is improved, and hence the design of the shape of the air outlet B can be improved.

Next, a state of the air outlet B when the housing 1 is viewed from the front will be described with reference to fig. 7.

As shown in fig. 7, the outlet B has a shape that expands in the vertical direction and the horizontal direction when viewed from the front. When the air outlet B is viewed from the front of the housing 1, the plurality of first ribs 83 appear to overlap inside the air outlet B. This is because the upper end 831 of the first rib 83 is located above the upper end 841 of the second rib 84, and is arranged along the front-rear direction of the plurality of first ribs 83 (see fig. 4), and each of the plurality of first ribs 83 has a long shape extending in the left-right direction. Therefore, when the air outlet B is viewed from the front of the housing 1, the plurality of first ribs 83 substantially cover the hole 82, and therefore the inside M of the housing 1 can be prevented from being visually recognized from the hole 82 (see fig. 2). As a result, the appearance of the air cleaner 100 can be effectively improved.

The embodiments of the present invention have been described above with reference to the drawings (fig. 1 to 7). However, the present invention is not limited to the above-described embodiments, and can be implemented in various embodiments (for example, (1) to (4)) without departing from the scope of the present invention. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above embodiments. For example, some of the components may be deleted from all the components shown in the embodiments. The drawings are schematically illustrated mainly for the sake of easy understanding, but the convenience of manufacturing the drawings, such as the number of the illustrated components, may be different from the actual one. The respective components shown in the above-described embodiments are examples, and are not particularly limited, and various modifications can be made within a range not substantially departing from the effects of the present invention.

(1) In the present embodiment, as shown in fig. 4, the flow rectification member 8 includes a first rib 83 and a second rib 84. However, the present invention is not limited thereto. The rectifying member 8 may be provided with the first ribs 83 but not with the second ribs 84. That is, the first rib 83 may be bridged over the hole 82, but the second rib 84 may not be bridged over. As a result, the number of components of the rectifying member 8 can be reduced.

(2) In the present embodiment, as shown in fig. 5, the lower end 832 of the first rib 83 and the lower end 842 of the second rib 84 are located at substantially the same height in the vertical direction. However, the present invention is not limited thereto. For example, as shown in fig. 8, the lower end 832 of the first rib 83 may be located below the lower end 842 of the second rib 84 in the vertical direction. As a result, the wind direction first rib 83 can be efficiently sucked.

As shown in fig. 9, in the vertical position, the lower end 832 of the first rib 83 may be located above the lower end 842 of the second rib 84 on the premise that the upper end 831 of the first rib 83 is located above the upper end 841 of the second rib 84. In this case, the vertical dimension d1 of the first rib 83 may be equal to or smaller than the vertical dimension d2 of the second rib 84 (d 1. ltoreq. d2), or the dimension d1 may be larger than the dimension d2(d 1. gtd 2). As a result, since the magnitude relation between the dimension d1 and the dimension d2 is not particularly limited, the degree of freedom in designing the flow straightening member 8 can be improved.

(3) Fig. 10 is a sectional view VIII-VIII of fig. 4. Fig. 10 is a cross-sectional view of ribs 83a to 83c among the plurality of first ribs 83. In fig. 10, the second rib 84 is not shown. Fig. 11 is a diagram showing a first modification of the first rib 83. Fig. 12 is a diagram showing a second modification of the first rib 83. A modification of the first rib 83 will be described with reference to fig. 9 to 12.

As shown in fig. 10, in the present embodiment, the vertical dimensions d1 of the ribs 83a to 83c are substantially the same. However, the present invention is not limited thereto.

As shown in fig. 11, in the first modification of the first rib 83, the vertical dimensions d1 of the plurality of first ribs 83 may be different from each other. For example, the dimension d1 of the ribs 83b and 83c located on the inner side among the plurality of first ribs 83 may be smaller than the dimension d1 of the rib 83a located on the outer side. As a result, the pressure loss of the wind flowing along the ribs 83b and 83c can be suppressed by reducing the dimension d1 of the ribs 83b and 83c, and the side leakage of the wind can be effectively suppressed by the ribs 83a by increasing the dimension d1 of the ribs 83 a. The inner side indicates a central portion side in the left-right direction. The outer side indicates an outer side in the left-right direction.

As shown in fig. 12, in the second modification of the first rib 83, one or a plurality of the first ribs 83 may be inclined with respect to the vertical direction. For example, the ribs 83a, 83b, and 83c have a shape extending in the vertical direction, but the rib 83a is inclined inward with respect to the vertical direction. As a result, the inclined ribs 83a can effectively suppress the side leakage of the wind.

(4) In the present embodiment, the air cleaner 100 includes louvers 9. However, the present invention is not limited thereto. The air cleaner 100 may not include the louver 9. An example of the device configuration of the air cleaner 100 in the case where the air cleaner 100 does not include the louver 9 will be described below.

As shown in fig. 5, the frame body 1 includes a top surface 1 a. The top surface 1a is a surface located inside M of the housing 1 and connected to the outlet B. The top surface 1a faces the rectifying member 8 (the first rib 83 and the second rib 84) from above.

When the air cleaner 100 does not include the louver 9, for example, the top surface 1a defines the discharge direction H of the air discharged from the air outlet B instead of the louver 9.

Hereinafter, a procedure of guiding air through the top surface 1a will be described.

The first rib 83 and the second rib 84 guide the wind fed from the wind feeding unit 6 so that the wind fed from the wind feeding unit 6 is directed toward the top surface 1 a. In this case, the predetermined direction (the direction in which the first ribs 83 and the second ribs 84 guide the air) is a direction toward the top surface 1 a. When the wind guided by the first rib 83 and the second rib 84 reaches the top surface 1a, the wind moves along the top surface 1 a. When the wind moving along the top surface 1a reaches the air outlet B, the wind is discharged from the air outlet B to the outside of the housing 1. In this case, the discharge direction H of the air discharged from the air outlet B is defined as a direction corresponding to the inclination direction of the top surface 1 a. As a result, if the louver 9 is not provided, the wind is discharged from the outlet B in a direction corresponding to the direction in which the top surface 1a is inclined. The first ribs 83 and the second ribs 84 regulate the flow of the wind fed from the blowing section 6 so that the wind is directed toward the top surface 1a by causing the wind to follow the first ribs 83 and the second ribs 84, respectively. Therefore, the air fed from the air blowing part 6 is suppressed from being fed to a place away from the top surface 1 a. As a result, when the wind is discharged from the outlet B, the wind can be prevented from being discharged in a direction deviating from a desired direction (a direction corresponding to the inclination direction of the top surface 1 a).
