  However, according to the conventional blower, the user who is away from the blower cannot easily identify the decoration or printing of the pressing area. For this reason, it is necessary to search for a predetermined pressing area after approaching the blower. In addition, since the user seated on the floor visually recognizes the operation panel on the upper surface of the housing from an oblique direction, it is not possible to easily identify the decoration and printing of the pressing area. For this reason, even if the air blower is installed in a reachable range, the user needs to be closer to the air blower to identify the predetermined pressing area. Therefore, there is a problem that the convenience of the blower is poor.

<First Embodiment>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of an air blower including the operation panel according to the first embodiment. In the figure, white arrows indicate the direction of air flow. The blower 1 (floor-standing electric device) includes a columnar casing 2 and a pedestal portion 3 disposed below the casing 2 and is installed on the floor surface of the room.

  The pedestal 3 has a circular shape in plan view, and supports the housing 2 that is erected on the upper surface. A power cord (not shown) is led to the peripheral surface of the pedestal 3. When a displacement motor (not shown) provided in the lower portion is driven, the housing 2 rotates in a horizontal plane with respect to the pedestal portion 3 around a rotation axis extending in the vertical direction provided in the center in the radial direction. Thereby, the housing | casing 2 rocks | swivels with a vertical rotating shaft, and reciprocates within a predetermined angle range, and swings.

  The housing | casing 2 is formed in the column shape extended vertically long vertically. The casing 2 has a circular bottom surface, and a portion from a substantially central portion to an upper end in the vertical direction is formed in a substantially rectangular parallelepiped shape. The upper part of the substantially rectangular parallelepiped shape has a longer front and rear length than a lateral width, and is curved so that the left and right side surfaces bulge outward.

  Both side surfaces of the upper part of the housing 2 are covered with a cover member 2a, and both side surfaces of the lower part are covered with a cover member 2b that opens a suction part 41 (first suction part) composed of a plurality of small holes. A notch is provided at the lower end of the cover member 2a. When the cover members 2a and 2b are attached to the housing 2, an opening 21a is formed by the notch and the upper end of the cover member 2b. The opening 21a opens over the front and rear end portions of the side surface of the housing 2, and the grill 8 is disposed in the opening 21a.

  An air outlet 5 is opened in the upper front surface of the housing 2. An operation panel 6 is provided on the upper surface of the housing 2. Details of the operation panel 6 will be described later.

  FIG. 2 shows a longitudinal sectional view of the grill 8. The grill 8 is formed to extend over the front and rear ends of the housing 2 below the outlet 5 and is screwed to a support member (not shown) inside the housing 2 at the front and rear ends. The lower end portion of the grill 8 is close to the cover member 2b, and the grill 8 has an inclined portion 8a that inclines in a direction away from the cover member 2a inward as it goes upward. A suction part 42 (second suction part) composed of a plurality of slits is formed in the inclined part 8a. Each slit which forms the suction part 42 is arranged below the blower outlet 5 and is inclined in a direction approaching the blower outlet 5 as it goes upward.

  The opening area of each slit of the suction part 42 is larger than the opening area of each small hole of the suction part 41. The suction part 41 and the suction part 42 form the suction port 4 for sucking indoor air.

  FIG. 3 is a side view showing the inside of the blower 1 with the cover members 2a, 2b and the grill 8 removed. A blower passage 20 is provided in the housing 2 so as to extend in the vertical direction and allow the suction port 4 and the blowout port 5 to communicate with each other. A blower fan 7 is disposed inside the blower passage 20 and on both sides of the lower portion of the housing 2.

  The blower fan 7 is constituted by a centrifugal fan such as a sirocco fan, and an air inlet (not shown) is arranged facing the air inlet 4. The exhaust port 7a of the blower fan 7 opens upward. The air sucked from the suction port 4 by the drive of the blower fan 7 flows toward the blower outlet 5. The blower fan 7 may be constituted by a turbo fan.

  The blower passage 20 extends toward the upper side downstream of the blower fan 7, curves toward the front blower outlet 5, and has a plurality of divided passages 22 divided by the partition plate 21. In the present embodiment, six dividing passages 22 are provided by five partition plates 21. The divided passages 22 are arranged in a line in the front-rear direction of the blower 1 at the inlet 23 and in a line in the vertical direction at the outlet 24. The partition plate 21 forms upper and lower wall surfaces of the divided passage 22, and six wind direction plates 25 are arranged at the outlet 5 so as to extend the partition plate 21 and the lower wall 26 of the blower passage 20.

  An ion generator 30 that generates ions is disposed between the blower fan 7 and the divided passage 22. Since the ion generator 30 is disposed downstream of the blower fan 7, it is possible to prevent the disappearance of ions due to the collision with the blower fan 7.

  FIG. 4 shows an external perspective view of the ion generator 30. The ion generator 30 is packaged by disposing a discharge electrode and other electronic components in a housing 31. The ion generator 30 includes a circuit unit (not shown), a positive ion generator 32P, and a negative ion generator 32N. The circuit unit is provided with a high voltage electricity generation circuit that generates a high voltage electric pulse by receiving power supply from the outside.

  The positive ion generator 32P includes a positive discharge electrode 33P, and the negative ion generator 32N includes a negative discharge electrode 33N. The two pairs of the positive discharge electrode 33P and the negative discharge electrode 33N are each formed in a needle shape, arranged side by side at a predetermined interval, and face the blower passage 20 through the opening.

  Both the positive ion generator 32P and the negative ion generator 32N are formed in the same structure. A high voltage generated by the high voltage electricity generation circuit is supplied to each of the positive discharge electrode 33P and the negative discharge electrode 33N to generate a discharge and release ions.

A voltage having an AC waveform or a pulse waveform is applied to the positive discharge electrode 33P and the negative discharge electrode 33N. A positive voltage is applied to the positive discharge electrode 33P, and hydrogen ions generated by corona discharge combine with moisture in the air to generate positive ions mainly composed of H ⁺ (H ₂ O) m.

A negative voltage is applied to the negative discharge electrode 33N, and oxygen ions generated by corona discharge combine with moisture in the air to generate negative ions mainly composed of O ₂ ⁻ (H ₂ O) n. Here, m and n are arbitrary natural numbers. H ⁺ (H ₂ O) m and O ₂ ⁻ (H ₂ O) n aggregate on the surface of airborne bacteria and odorous components and surround them.

Then, as shown in the formulas (1) to (3), the active species [.OH] (hydroxyl radical) and H ₂ O ₂ (hydrogen peroxide) are aggregated and formed on the surface of the microorganism or the like by collision. Destroy airborne bacteria and odorous components. Here, m ′ and n ′ are arbitrary natural numbers. Therefore, the ion generator 30 releases positive ions and negative ions into the air passage 20, and positive ions and negative ions are sent out from the outlet 5. Thereby, indoor sterilization and deodorization can be performed, for example.

H ⁺ (H ₂ O) m + O ₂ ⁻ (H ₂ O) n → OH + 1 / 2O ₂ + (m + n) H ₂ O (1)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ 2 OH + O ₂ + (m + m ′ + n + n ′) H ₂ O (2)
_{^{H + (H 2 O) m}} + H + (H 2 O) m '+ O 2 - (H 2 O) n + O 2 - (H 2 O) n'
→ H ₂ O ₂ + O ₂ + (m + m ′ + n + n ′) H ₂ O (3)

  In the present embodiment, positive ions and negative ions are generated by the ion generator 30, but only positive ions or only negative ions may be generated.

  Alternatively, the ion generator 30 may be an electrostatic atomizer that generates ions composed of charged fine particle water. Charged fine particle water containing a radical component is generated by the electrostatic atomizer. That is, condensation water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer by the Peltier element. Next, when a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water. Further, negative ions released into the air together with the charged fine particle water are also generated from the discharge electrode.

  FIG. 5 shows a top view of the operation panel 6. FIG. 6 shows a top view of the base 61 of the operation panel 6. 5 and 6, the lower and upper portions respectively indicate the front and rear of the housing 2. 7 and 8 show a cross-sectional view taken along line AA in FIG. 5 and a cross-sectional view taken along line BB in FIG. 6, respectively.

  The operation panel 6 includes a base 61, a decorative sheet 62, and a plurality of switches 63 (see FIG. 8). The base 61 is made of a resin molded product, and has a plurality of recessed portions 61d recessed on the upper surface. An opening 61a is provided in the recess 61d. Thereby, the opening 61 a is arranged at a position lower than the upper surface of the base 61. A pressing portion 61b is disposed in each opening 61a, and the periphery of the opening 61a and the pressing portion 61b are connected by a connecting portion 61c. The upper surface of the pressing part 61b is arranged on the same plane as the upper surface of the base 61, and the lower end of the pressing part 61b protrudes downward from the recessed part 61d. When the pressing portion 61b is pushed from above, the connecting portion 61c is elastically deformed. Thereby, the press part 61b can move below.

  As shown in FIG. 8, the switch 63 is disposed below the pressing portion 61b via a predetermined gap SP. When the pressing portion 61b is pressed downward, the pressing portion 61b moves downward to press the switch 63. Thereby, various operation | movement settings of the air blower 1 are performed.

  The decorative sheet 62 is formed with a thickness t of, for example, 0.25 mm, and is attached to the upper surface of the base 61. The decorative sheet 62 is provided with a plurality of pressing areas 16a, 16b, and 16c that face the depression 61d and press the switch 63 via the pressing part 61b. In the following description, the pressing areas 16a, 16b, and 16c may be collectively referred to as “pressing area 16”.

  An annular groove portion 18 is formed at the boundary between the non-pressing region 17 and the pressing region 16 that are not opposed to the pressing portion 61b. At this time, the pressing area 16 and the non-pressing area 17 are arranged on substantially the same plane. Thereby, the press area | region 16 does not protrude with respect to the non-press area | region 17, but the beauty | look of the operation panel 6 can be improved and a high-class feeling can be obtained.

  The depth d of the groove part 18 is formed to 0.5 mm, for example, and the width w is formed to 0.75 mm, for example. As a result, the pressing area 16 disposed in the same plane with respect to the non-pressing area 17 can be easily lowered via the groove 18 by pressing, and the switch 63 can be easily operated.

  At this time, if the depth d of the groove 18 is shallower than twice the thickness t of the decorative sheet 62, the amount of lowering of the pressing area 16 is reduced and a click during pressing cannot be obtained. Moreover, if the width w of the groove 18 is narrower than three times the thickness t of the decorative sheet 62, the pressing region 16 cannot be easily lowered. For this reason, it is desirable to form the depth d of the groove 18 to be twice or more the thickness t of the decorative sheet 62 and to form the width w of the groove 18 to be three or more times the thickness t of the decorative sheet 62. .

  Each pressing area 16 is decorated with characters and decorations by printing. You may decorate each press area | region 16 by sheet forming. Thereby, the user can identify and operate the press area | region 16 in the vicinity of the air blower 1 easily. The pressing area 16a instructs to start driving the blower 1, and the pressing area 16b instructs to stop driving the blowing apparatus 1. Further, it is possible to instruct to change the air volume of the blower fan 7, turn on / off the ion generator 30, turn on / off the swing of the housing 2, and the like by the pressing area 16 c.

  The pressing area 16a is formed to have a larger area than the pressing areas 16b and 16c. The distance S2 between the pressing area 16a and the adjacent pressing area 16c is longer than the distance S1 between the adjacent pressing areas 16c.

  FIG. 9 shows an exploded perspective view of the decorative sheet 62. FIG. 9 illustrates a part of the hairline 621a. The decorative sheet 62 includes a hairline layer 62a, a first smoke layer 62b, a second smoke layer 62c, and a reflective layer 62d. The hairline layer 62a is formed of a resin sheet that transmits light, and the hairline 621a, which is a plurality of fine linear streaks, is formed on the entire surface so as to extend in the short direction of the decorative sheet 62 (the horizontal direction of the housing 2) Is done. The hairline 621a is arranged in parallel in the longitudinal direction of the decorating sheet 62 (the front-rear direction of the housing 2) at a predetermined period (for example, a period of several μm to several tens of μm). The hairline 621a has a depth of, for example, several μm to several tens of μm. Thereby, the light of a specific direction is easy to permeate | transmit on the surface of the hairline layer 62a, and the light of another direction diffuses, Therefore The decorating sheet 62 can give a metallic texture. Note that hairlines 621 a extending in the longitudinal direction of the decorative sheet 62 may be arranged in parallel in the short direction of the decorative sheet 62.

  The first smoke layer 62b and the second smoke layer 62c are formed to be translucent, for example, by applying a black coating of 8 μm to the back surface of the hairline layer 62a. The first smoke layer 62b is provided with an opening 621b facing the pressing region 16a, and the second smoke layer 62c is provided in the opening 621b.

  The visible light transmittance of the first smoke layer 62b and the second smoke layer 62c is, for example, 50% or less. Further, the visible light transmittance of the second smoke layer 62c is formed higher than that of the first smoke layer 62b.

  The reflective layer 62d is formed by applying silver paint on the back surfaces of the first smoke layer 62b and the second smoke layer 62c, and reflects the light incident from the hairline layer 62a toward the surface of the hairline layer 62a. The reflective layer 62d may be formed by vapor-depositing aluminum or silver on the back surfaces of the first smoke layer 62b and the second smoke layer 62c.

  In addition, when a user looks at the decoration sheet 62 of the operation panel 6 from substantially right above under indoor lighting, the pressing region 16a and other regions (the pressing regions 16b and 16c and the non-pressing region 17) The visible light transmittance of the first smoke layer 62b and the second smoke layer 62c is set so that the contrast is not substantially recognized.

  In the air blower 1 having the above configuration, when the pressing area 16a of the operation panel 6 is pressed, the air blowing fan 7 is driven, and the operation of the air blower 1 is started. At this time, when one pressing area 16c is pressed, the ion generator 30 is driven. Thereby, the indoor air flows into the air passage 20 from the suction port 4 at the lower part of the housing 2. The air flowing into the air passage 20 includes ions generated by the ion generator 30.

  The airflow containing ions is divided into a plurality of divided passages 22 and circulates. The air current is guided in the outer circumferential direction of the air passage 20 by the centrifugal force of the air fan 7 formed of a centrifugal fan. At this time, the airflow is uniformly dispersed from the inlet portion 23 of the blower passage 20 to each of the divided passages 22 to prevent the airflow from being biased. And the airflow which distribute | circulates each division | segmentation channel | path 22 is uniformly sent in the direction according to the wind direction board 25 from the blower outlet 5. FIG. Thereby, the airflow containing ions can diffuse into the room and sterilize the room.

  Moreover, when the ion generator 30 is stopped and the blower fan 7 is driven, it is possible to blow air toward the user and circulate indoor air.

  At this time, indoor air can be sucked from the suction portion 42 in addition to the suction portion 41. Therefore, the blowing efficiency of the blower 1 can be improved. Further, since the suction portion 42 is provided in the inclined portion 8a of the grill 8, the suction of the ions that are sent from the outlet 5 and are present above the opening 21a when the casing 2 is swung into the suction portion 42 is reduced. can do. Therefore, ions can be efficiently distributed in the room.

  Moreover, since the upper part of the suction part 42 is covered with the cover member 2a, for example, when a liquid such as water flows from the upper part of the housing 2, the intrusion of water into the suction part 42 can be reduced.

  Table 1 shows the result of a comparative experiment on the discrimination of the operation panel of this embodiment and each comparative example. FIG. 10 is a view for explaining this experiment, and shows a view of the housing 2 from the front. In addition, Lexan (registered trademark) 8A37 manufactured by SABIC Japan LLC having a thickness of 250 μm was used as the hairline layer 62a. In Comparative Example 1, a transparent layer having a visible light transmittance of approximately 100% was disposed in place of the second smoke layer 62c. In Comparative Example 2, the second smoke layer 62c has the same visible light transmittance as that of the first smoke layer 62b.

  The experiment method was performed by arranging Comparative Examples 1 and 2 and the operation panel 6 of the present embodiment on the upper surface of the housing 2 and varying the angle θ of the observer's line of sight EL with respect to the normal N of the upper surface of the housing 2. . The distance between the observer's eyes E and the decorative sheet 62 is 1 m. In Comparative Examples 1 and 2, the angle θ is changed to the side of the housing 2, and in the present embodiment, the distance θ is on the front and side of the housing 2. Each angle θ is variable.

  The identification result is indicated by “◯” when the observer determines that the contrast is high and easy to identify, and “Δ” indicates the case where it is determined that the contrast is low but identification is possible. A case where there is almost no contrast and the observer determines that identification is difficult is indicated by “x”.

  According to Table 1, in Comparative Example 1, the contrast is high when the angle θ is in the range of 0 ° to 90 °, and in Comparative Example 2, there is almost no contrast when the angle θ is in the range of 0 ° to 90 °. On the other hand, when this embodiment is viewed from the side of the housing 2, there is almost no contrast when the angle θ is in the range of 0 ° to 30 °. However, identification was possible when the angle θ was 45 °, and the contrast was high and easy to identify in the range of 60 ° to 90 °. Further, when the present embodiment is viewed from the front of the housing 2, there is almost no contrast when the angle θ is in the range of 0 ° to 45 °. However, identification was possible when the angle θ was 60 °, and when the angle θ was 90 °, the contrast was high and identification was easy.

  The light incident on the decorative sheet 62 passes through the first smoke layer 62b and the second smoke layer 62c and is reflected by the reflection layer 62d. The light reflected by the reflective layer 62d passes through the first smoke layer 62b and the second smoke layer 62c and travels toward the surface of the hairline layer 62a. At this time, the light emitted from the surface of the hairline layer 62a in the normal N direction (directly above the housing 2) increases the light incident from the normal N direction. The light incident from the normal N direction is reflected once by the reflective layer 62d and then reaches the surface of the hairline layer 62a at an incident angle smaller than the critical angle and is emitted. For this reason, when the operation panel 6 is viewed from directly above the housing 2 (the angle θ is 0 °), the contrast between the pressing area 16a and the non-pressing area 17 becomes low.

  In the present embodiment, when the user approaches the blower 1, the operation panel 6 is visually recognized from substantially above. At this time, there is almost no contrast between the pressing area 16a and the non-pressing area 17, but the pressing area 16a is identified by the groove 18 or printing (characters or decoration). Thereby, the color scheme of the decorative sheet 62 can be unified, and the beauty can be improved without impairing the uniformity of the design of the operation panel 6.

  On the other hand, the light that is inclined with respect to the normal N and is emitted from the surface of the hairline layer 62a is often reflected a plurality of times between the surface of the hairline layer 62a and the reflective layer 62d before being emitted. That is, the light that has been reflected by the reflective layer 62d and has reached the surface of the hairline layer 62a at an incident angle larger than the critical angle is totally reflected by the surface of the hairline layer 62a. The light totally reflected on the surface of the hairline layer 62a is reflected again by the reflective layer 62d. Then, the light whose incident angle to the surface of the hairline layer 62a is smaller than the critical angle is emitted from the surface of the hairline layer 62a. At this time, since the transmittance of the first smoke layer 62b is lower than the transmittance of the second smoke layer 62c, the amount of light absorbed by the first smoke layer 62b while the light is reflected a plurality of times. And the amount of light absorbed by the second smoke layer 62c increases. Thereby, when an observer sees the decoration sheet 62 of the operation panel 6 from diagonally upward, the contrast of the press area | region 16a and the non-press area | region 17 will become high.

  According to the present embodiment, the decorative sheet 62 includes a hairline layer 62a, a first smoke layer 62b, a second smoke layer 62c, and a reflective layer 62d. Thereby, for example, when the angle θ (see FIG. 10) is large, such as when the user is away from the blower 1 or sitting on the floor, the pressing area 16a and the non-pressing area 17 And the user can easily identify the pressing area 16a. Therefore, it is not necessary to search the pressing area 16a after approaching the blower 1, and the convenience of the blower 1 can be improved.

  On the other hand, for example, when the user approaches the blower 1 and the angle θ decreases, the contrast between the pressing area 16a and the non-pressing area 17 decreases. Therefore, the aesthetics can be improved without impairing the uniformity of the design of the operation panel 6.

  Moreover, since it is not necessary to illuminate the press area | region 16a or the vicinity of the press area | region 16a with LED etc., the increase in the manufacturing cost and power consumption of the air blower 1 can be prevented.

  Further, the visible light transmittance of the first smoke layer 62b and the second smoke layer 62c is set to 50% or less. Thereby, even if the 1st smoke layer 62b and the 2nd smoke layer 62c are formed in a different transmittance | permeability, the contrast of the press area | region 16a and the non-press area | region 17 seen from right above can be made low. Therefore, the uniformity of the design of the decorative sheet 62 can be easily ensured.

  The hairline layer 62a is made of a resin sheet, and the first smoke layer 62b, the second smoke layer 62c, and the reflective layer 62d are formed on the resin sheet by coating. Thereby, the decorating sheet 62 can be formed easily. In addition, you may form the 1st smoke layer 62b, the 2nd smoke layer 62c, and the reflection layer 62d with a sheet-like member.

  Moreover, the operation of the blower 1 (floor-standing type electric device) is started by the switch 63 facing the second smoke layer 62c. Thereby, the distinguishability of the press area | region 16a with high use frequency can be improved, and the convenience of the air blower 1 can be improved more. The operation of the blower 1 may be stopped by the switch 63 facing the second smoke layer 62c.

  The decorative sheet 62 has a groove 18 that forms a boundary between the pressing area 16 and the non-pressing area 17, and the pressing area 16 and the non-pressing area 17 are formed on substantially the same plane. It is desirable that the depth d of the groove 18 is formed to be twice or more the thickness t of the decorative sheet 62 and the width w of the groove 18 is formed to be three or more times the thickness t of the decorative sheet 62. As a result, the switch 63 can be easily operated via the pressing region 16, and the aesthetic appearance of the operation panel 6 can be improved and a high-class feeling can be produced.

Second Embodiment
Next, a second embodiment of the present invention will be described. FIG. 11 shows a perspective view of a blower provided with the operation panel of the present embodiment. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the configuration of the operation panel 6 is different from that of the first embodiment. Other parts are the same as those in the first embodiment.

  The operation panel 6 has one switch 63. When the switch 63 is pressed through the pressing area 16a, the operation of the blower 1 is started. When the switch 63 is pressed through the pressing area 16a during operation, the operation of the blower 1 is stopped.

  In this embodiment, the same effect as that of the first embodiment can be obtained.

<Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 12 shows a perspective view of a blower provided with the operation panel of the present embodiment as viewed from the back side of the housing. For convenience of explanation, the same parts as those in the first embodiment shown in FIGS. In the present embodiment, the configuration of the operation panel 6 and the arrangement of the grills 8 are different from those in the first embodiment. Other parts are the same as those in the first embodiment.

  The opening 21a and the grill 8 are arranged at the rear part of the side surface of the housing 2 and are not arranged at the front part of the side surface. In addition, the opening area of the opening part 21a and the suction part 42 of this embodiment is substantially the same as the opening area of the opening part 21a and the suction part 42 of 1st Embodiment. Thereby, the distance between the blower outlet 5 of the front surface and the suction part 42 can be lengthened. Therefore, it is possible to further reduce the suction of the ions sent from the outlet 5 into the suction portion 42.

  Moreover, the area of each press area | region 16a-16c of the operation panel 6 is substantially the same, and the press area | regions 16a-16c are arranged in parallel at equal intervals. Thereby, the unification of the design of the operation panel 6 is improved, and the aesthetic appearance can be further improved.

  In this embodiment, the same effect as that of the first embodiment can be obtained.

  In addition, you may distribute | arrange the opening part 21a and the grill 8 of this embodiment in the front part of the side surface instead of arranging in the rear part of the side surface of the housing | casing 2. In this case, although the distance between the suction part 42 and the blower outlet 5 becomes short, since the air flow which is sent out from the blower outlet 5 and contains the ion along the cover member 2a is easy to peel at the opening part 21a, the suction of the ion Suction into the portion 42 can be reduced.

  In the first to third embodiments, the operation panel 6 provided in the blower 1 has been described as an example. However, the operation panel may be used for other floor-standing electric appliances (for example, a floor-standing heater or a floor-humidifier). 6 may be provided.

  ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the operation panel which has a decorating sheet which covers a switch, and a floor-standing type electric device provided with the same.
