Description

[Technical field]

[0001] The present disclosure relates to a blower device. [Background technology]

[0002] In a conventional air blower, the air blower is installed on the back side of the desk and blows out cold air from a cold air outlet with an opening above the desk plate, and the cold air flows from above the desk plate around the edge of the desk plate and through the space below the desk plate to be sucked into the air intake port. As a result, a zoning area is formed around the desk and around the user using the desk by the cold air (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 1-067542 Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional blower devices do not take into account the flow characteristics of the air being drawn into the air intake, so there is room for improvement in terms of the concentration of the cold air blown out from the cold air outlet toward the air intake.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a technology that efficiently zones the area around a user sitting at a desk by using circulating airflow. [Means for solving the problem]

[0006] In order to solve the above problems, one embodiment of the blower device disclosed herein is a blower device installed on a desk having a tabletop, a deflector plate arranged on the rear and upper side of the tabletop, a left side plate supporting the left side of the tabletop from below, and a right side plate supporting the right side of the tabletop from below, and is equipped with an intake port arranged on the front side of the blower device, a blower arranged inside the blower device, a first outlet arranged on the rear side of the tabletop, a second outlet arranged on the left side plate, and a third outlet arranged on the right side plate. When the blower operates, air in the space under the desk is sucked into the inside of the blower device through the intake port, and when the blower operates, the air sucked into the inside of the blower device is blown out from the first outlet toward the deflector, and the deflector deflects the air blown out from the outlet toward the front side, and when the blower operates, the air sucked into the inside of the blower device is blown out from the second and third outlets toward the front side, and the air deflected by the deflector passes between the air blown out from the second outlet and the air blown out from the third outlet and heads toward the intake port. Effect of the Invention

[0007] According to the present disclosure, the area around a user sitting at a desk can be efficiently zoned by circulating airflow. [Brief description of the drawings]

[Diagram 3] FIG. 2 is a perspective view showing an airflow blown by the blower device of FIGS. [Figure 4] FIG. 13 is a perspective view showing the configuration of a first desk and a second desk according to a modified example. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The examples described below each show a preferred specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, the arrangement and connection of the components, as well as the steps (processes) and the order of the steps shown in the following examples are merely examples and are not intended to limit the present disclosure. Therefore, among the components in the following examples, those components that are not described in the independent claims showing the highest concept of the present disclosure are described as optional components. In addition, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated descriptions are omitted or simplified.

[0010] 1(a)-(d) show the configuration of the desk 2. As shown in FIG. 1(a)-(d), a Cartesian coordinate system consisting of an x-axis, a y-axis, and a z-axis is defined. The x-axis and the y-axis are mutually orthogonal within the plane of the top board 7 of the desk 2. The z-axis is perpendicular to the x-axis and the y-axis, and extends in the height direction of the desk 2. The positive directions of the x-axis, the y-axis, and the z-axis are defined as the directions of the arrows in FIG. 1(a)-(d), and the negative directions are defined as the directions opposite to the arrows. In the following, the positive side of the x-axis is called the "front side", the negative side of the x-axis is called the "rear side", the positive side of the y-axis is called the "right side", the negative side of the y-axis is called the "left side", the positive side of the z-axis is called the "upper side", and the negative side of the z-axis is called the "lower side". Additionally, the direction in which the x-axis extends is called the "front-to-back direction," the direction in which the y-axis extends is called the "left-to-right direction," and the direction in which the z-axis extends is called the "up-down direction."

[0011] Fig. 1(a) is a perspective view of the desk 2, Fig. 1(b) is a top view of the desk 2 seen from above, Fig. 1(c) is a front view of the desk 2 seen from the front side, and Fig. 1(d) is a side view of the desk 2 seen from the right side. The desk 2 includes a left side panel 5, a right side panel 6, a top panel 7, a back panel 8, and a deflector panel 17.

[0012] The top board 7 has a plate-like shape including a plane extending in the xy plane. The top board 7 is a tool used by a user sitting at the desk 2 to work, and a personal computer, documents, etc. are placed on the top board 7. The left side board 5 is connected to the left side of the top board 7. The left side board 5 supports the left side of the top board 7 from below. In addition, a part of the rear side of the left side board 5 extends above the top board 7. The right side board 6 is connected to the right side of the top board 7. The right side board 6 supports the right side of the top board 7 from below. In addition, a part of the rear side of the right side board 6 extends above the top board 7.

[0013] A deflection plate 17 is connected in a bridge shape between the upper end of the left side plate 5 and the upper end of the right side plate 6. Therefore, the deflection plate 17 is disposed on the rear and upper side of the top plate 7. Also, on the rear side of the top plate 7, a back plate 8 is disposed in an area surrounded by the left side plate 5, the right side plate 6, and the deflection plate 17. Here, below the top plate 7, the space surrounded by the left side plate 5, the right side plate 6, and the top plate 7 is a lower space 9, and the space above the top plate 7 is an upper space 10.

[0014] The blower 1 is provided in the lower space 9 and on the back side of the table top 7, and supports the desk 2 by having the bottom surface of the blower 1 contact the installation surface. The blower 1 is a device for forming a zoning area around the desk 2 by blowing out airflow, which will be described later, and by forming this zoning area, locally zoning only the area around the user facing the desk 2. The blower 1 includes an intake port 11, a first outlet 13, a second outlet 14, and a third outlet 15.

[0015] The air inlet 11 is formed in one horizontally long slit shape at the rear side of the lower space 9, near the feet of the user. The air inlet 11 is disposed on the front side of the blower 1. The air inlet 11 draws air from the lower space 9 into the inside of the blower 1.

[0016] The first air outlet 13 is disposed on the rear side of the tabletop 7. The first air outlet 13 is a horizontally elongated slit extending in the left-right direction from the left panel 5 to the right panel 6 on the tabletop 7. The first air outlet 13 blows air vertically upward from the tabletop 7 of the desk 2.

[0017] The second air outlet 14 is disposed in front of the left side panel 5. The second air outlet 14 is a vertically elongated slit extending in the up-down direction. Here, it is composed of a plurality of slits, but it may be a single slit. The second air outlet 14 blows air toward the front side. The third air outlet 15 is disposed in front of the right side panel 6. The third air outlet 15 is a vertically elongated slit extending in the up-down direction. Here, it is composed of a plurality of slits, but it may be a single slit. The third air outlet 15 blows air toward the front side. The second air outlet 14 and the third air outlet 15 are disposed closer to the front side than the air inlet 11.

[0018] The effective ingredient imparting unit 50 is arranged next to the first air outlet 13 on the top plate 7, and is, for example, a fragrance generator, a heater, or an air purifier. The fragrance component from the fragrance generator, the heating from the heater, and the air purification from the air purifier are effective ingredients for the air. The effective ingredient imparting unit 50 imparts the effective ingredient to the air blown out from the first air outlet 13. The effective ingredient imparting unit 50 may be arranged inside the air blower 1.

[0019] 2(a)-(b) are cross-sectional perspective views of the blower 1. FIG. 2(a) shows the airflow path of the airflow sucked into the inside of the desk 2, and is a cross-sectional perspective view of FIG. 1(a) taken along the line AA. The blower 12 is one of the main components constituting the blower 1. The blower 12 moves the air by sucking in the air from the inlet 11 and blowing out the air from the first outlet 13, the second outlet 14, and the third outlet 15. The blower 12 is provided in the center of the inside of the blower 1, and the blower inlet 21 that sucks in the air into the inside of the blower 12 faces upward. The blower 12 is arranged so that the blower outlet 23 that blows out the high-pressure air 22, which is the air that has been pressurized from the sucked air, faces downward. The inlet 11 and the blower inlet 21 communicate with each other on the front side of the blower 1. This allows the air introduced from the suction port 11 to flow to the blower suction port 21.

[0020] When the blower 12 operates, air in the space 9 below the desk 2 passes through the inlet 11 and is sucked into the inside of the blower device 1, flows through the suction air passage 27 formed by communication between the inlet 11 and the blower inlet 21, and is sucked into the blower inlet 21. The sucked air is pressurized by the blower 12 and blown out from the blower outlet 23 as high-pressure air 22.

[0021] Fig. 2(b) is a perspective view of the AA cross section of Fig. 1(a), showing the air path of the airflow until it is blown out of the desk 2. The fan outlet 23 and the first outlet 13 communicate with each other from the left and right sides of the fan 12. This allows the air discharged from the fan outlet 23 to flow to the first outlet 13. The fan outlet 23 and the second outlet 14 also communicate with each other from the left and right sides of the fan 12, and the fan outlet 23 and the third outlet 15 (not shown) also communicate with each other from the left and right sides of the fan 12. This allows the air discharged from the fan outlet 23 to flow to the second outlet 14 and the third outlet 15.

[0022] A purification filter 25 is provided in the communication space extending from the blower outlet 23 to the first outlet 13. The purification filter 25 is for removing dirt, dust, etc. from the circulating high-pressure air 22 to purify the high-pressure air 22, and is disposed above the blower 12 and below the first outlet 13. For example, a HEPA (High Efficiency Particulate Air) filter is used as the purification filter 25.

[0023] The high-pressure air 22 flows through an outlet air passage 28 formed by communication between the blower outlet 23 and the first outlet 13, between the blower outlet 23 and the second outlet 14, and between the blower outlet 23 and the third outlet 15 (not shown). As a result, the high-pressure air 22 is blown out from the first outlet 13, the second outlet 14, and the third outlet 15. Of these, the high-pressure air 22 blown out from the first outlet 13 passes through a purification filter 25 on the way, and is therefore purified air.

[0024] The blow-out air passage 28 includes a common blow-out air passage 28a, a first blow-out air passage 28b, and a second blow-out air passage 28c. The common blow-out air passage 28a is a common air passage from the blower outlet 23 to the blow-out air passage branching portion 29 located at the lower left and lower right of the blower 12. The first blow-out air passage 28b is a downstream air passage branching from the blow-out air passage branching portion 29, and is an air passage from the blow-out air passage branching portion 29 to the first blow-out outlet 13. The second blow-out air passage 28c is a downstream air passage branching from the blow-out air passage branching portion 29, and is an air passage from the blow-out air passage branching portion 29 to the second blow-out outlet 14. Although omitted in FIG. 2(b), an air passage from the blow-out air passage branching portion 29 to the third blow-out outlet 15 is also included. Intake air passage 27 and outlet air passage 28 are separated by a partition wall provided inside blower device 1 so as not to intersect with each other.

[0025] When the blower 12 operates, air sucked into the inside of the blower device 1 is blown out from the first outlet 13 toward the deflector 17. When the blower 12 operates, air sucked into the inside of the blower device 1 is blown out from the second outlet 14 and the third outlet 15 toward the front side.

[0026] 3 is a perspective view showing an airflow blown by the blower 1. The first air outlet 13 blows air as a first airflow 63 toward the upper deflector 17. The deflector 17 deflects the first airflow 63 blown out from the first air outlet 13 toward the front side. This corresponds to deflecting the first airflow 63 toward the upper side of the user of the desk 2. At that time, an effective ingredient is imparted to the first airflow 63 by the effective ingredient imparting unit 50.

[0027] Further, the second air outlet 14 blows air toward the front side as a second outlet airflow 64, and the third air outlet 15 blows air toward the front side as a third outlet airflow 65. As a result, an air curtain due to the second outlet airflow 64 is formed at the left end of the desk 2, and an air curtain due to the third outlet airflow 65 is formed at the right end of the desk 2. The space sandwiched between the air curtain due to the second outlet airflow 64 and the air curtain due to the third outlet airflow 65 communicates with the lower space 9 in the lower portion of the tabletop 7.

[0028] As described above, the air in the lower space 9 is sucked into the intake port 11 (not shown) of the blower 1. Therefore, the lower space 9 becomes negative pressure, and the air in the space sandwiched between the air curtain by the second blown airflow 64 and the air curtain by the third blown airflow 65 is sucked into the lower space 9. As a result, the space sandwiched between the air curtain by the second blown airflow 64 and the air curtain by the third blown airflow 65 also becomes negative pressure, making it easier for the first blown airflow 63 to flow in. The first blown airflow 63 deflected by the deflector 17 in this way passes through the space sandwiched between the air curtain by the second blown airflow 64 and the air curtain by the third blown airflow 65 toward the intake port 11 of the lower space 9.

[0029] (Modification) 4 is a perspective view showing the configuration of the first desk 2a and the second desk 2b according to the modified example. The first desk 2a and the second desk 2b are arranged with their back sides facing each other. The first desk 2a and the second desk 2b are configured in the same way as the previous desk 2, but do not include a back panel 8.

[0030] In the case where the air quality preferred by the user of the first desk 2a is different from the air quality preferred by the user of the second desk 2b, a first blower 1a is installed on the first desk 2a, and a second blower 1b (not shown) is installed on the second desk 2b. The air quality corresponds to the above-mentioned effective ingredient. In addition, a first effective ingredient application unit 50a is installed on the first desk 2a, and a second effective ingredient application unit 50b (not shown) is installed on the second desk 2b. In this situation, the first blower 1a and the second blower 1b operate separately.

[0031] In the case where the preferred air quality of the user at the first desk 2a and the preferred air quality of the user at the second desk 2b are assumed to be the same, the first blower 1a is installed at the first desk 2a, but the blower 1 is not installed at the second desk 2b. Therefore, only one first air outlet 13a is installed. Also, the first effective ingredient imparting unit 50a is installed at the first desk 2a, but the effective ingredient imparting unit 50 is not installed at the second desk 2b. In this situation, the first blower 1a operates in the same way as the previous blower 1.

[0032] According to this embodiment, the air deflected by the deflector 17 passes between the air blown out from the second air outlet 14 and the air blown out from the third air outlet 15 and heads toward the air inlet 11, so that the air deflected by the deflector 17 can be efficiently sucked into the air inlet 11. In addition, because the air deflected by the deflector 17 is efficiently sucked into the air inlet 11, the area around the user sitting at the desk 2 can be efficiently zoned by a circulating airflow.

[0033] In addition, since the second air outlet 14 and the third air outlet 15 are disposed closer to the front than the air inlet 11, the isolation of the lower space 9 can be improved by the air curtain created by the second air outlet 14 and the air curtain created by the third air outlet 15. In addition, since the isolation of the lower space 9 is improved, the air deflected by the deflection plate 17 can be efficiently sucked in by the air intake by the air inlet 11. In addition, the effective ingredient imparting section 50 imparts effective ingredients to the air, so that the comfort of the user of the desk 2 can be improved.
