Description

[Technical field]

[0001] The present invention relates to a discharge device holding member for holding a discharge device, and to an electric device. [Background technology]

[0002] As a related art, an electrical device to which a discharge device such as an ion generating device can be attached is known (for example, see Patent Document 1). In the electrical device according to the related art, the discharge device has a first discharge electrode and a second discharge electrode, and generates positive ions and negative ions by generating a discharge between the first discharge electrode and the second discharge electrode and an induction electrode. Such a discharge device is attached to a discharge device holding member (device mounting part) provided in an air passage.

[0003] In the related art, the discharge device holding member protrudes the first discharge electrode and the second discharge electrode into the air passage so that they are aligned in a direction intersecting the flow direction of the air current (wind) in the air passage. Furthermore, the discharge device holding member extends parallel to the flow direction of the air current and has a partition wall (partition member) whose upstream end of the air current is located between the first discharge electrode and the second discharge electrode in the arrangement direction of the first discharge electrode and the second discharge electrode and upstream of the first discharge electrode and the second discharge electrode. This partition wall can prevent a situation in which the discharge product (positive ions) from the first discharge electrode and the discharge product (negative ions) from the second discharge electrode of the discharge device recombine and decrease.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. The following embodiment is an example of the present invention, and is not intended to limit the technical scope of the present invention.

[0012] (Embodiment 1) [1] Overall structure First, the overall configuration of a blower 100 according to this embodiment will be described with reference to FIGS. 1 to 5. FIG.

[0013] In this embodiment, for ease of explanation, the vertical direction when the fan 100 is in a usable state is defined as the up-down direction D1. Furthermore, the left-right direction D2 is defined based on the direction in which the fan 100 is viewed from the front, and the front side of the fan 100 is defined as the front and the back side as the rear, defining the front-rear direction D3. However, these directions are not intended to limit the usage direction of the fan 100 (the direction during use).

[0014] 1 and 2, the blower 100 is used while placed on an installation surface X1, which may be, for example, a floor surface of a room in a house. The blower 100 stands on the installation surface X1 while placed on the installation surface X1. That is, the blower 100 according to this embodiment is a free-standing and portable device, and the user can freely carry the blower 100 and install it at any position on the installation surface X1.

[0015] The blower 100 includes a housing 1, an operating unit 2, an air intake 31 and an air outlet 32, a pair of fans 33, 34, a pair of filters 35, 36, an inner cover 17, a body 4, a discharge device 5, a pair of heat sources 37, 38 (see Figure 5), and a control unit 7 (see Figure 5).

[0016] In this embodiment, as an example, the housing 1 has a generally cylindrical shape having a length in the up-down direction D1. The housing 1 can have various shapes, and may be, for example, a rectangular prism shape other than a cylindrical shape. The housing 1 has a bottom panel 11, a top panel 12, a front panel 13, a back panel 14, and a pair of side panels 15 and 16.

[0017] The housing 1 has a bottom panel 11 and a top panel 12 at both ends in the up-down direction D1. The bottom panel 11 is a disk-shaped panel facing downward, and comes into contact with the installation surface X1 when the fan 100 is installed on the installation surface X1. The top panel 12 is a disk-shaped panel facing upward.

[0018] The housing 1 has a front panel 13 and a back panel 14 at both ends in the front-rear direction D3, and has two side panels 15, 16 at both ends in the left-right direction D2. The front panel 13, the back panel 14, and the two side panels 15, 16 form the outer periphery of the housing 1, which has a substantially cylindrical shape.

[0019] The front panel 13 is a panel facing forward, and is formed in a generally rectangular shape having a length in the vertical direction D1 when viewed from the front. The back panel 14 is a panel facing backward, and is formed in a generally rectangular shape having a length in the vertical direction D1 when viewed from the rear. The side panel 15 is a panel facing left, and is formed in a generally rectangular shape having a length in the vertical direction D1 when viewed from the left side. The side panel 16 is a panel facing right, and is formed in a generally rectangular shape having a length in the vertical direction D1 when viewed from the right side.

[0020] The front panel 13, the back panel 14, and the two side panels 15, 16 are each formed in a generally arc shape with the center portion convex outward in a plan view. Therefore, the front panel 13, the back panel 14, and the two side panels 15, 16 form an outer peripheral surface that is generally circular in a plan view. However, there is a gap between the front panel 13 and each of the two side panels 15, 16, and the air blown out from the air outlet 32 ​​passes through the gap.

[0021] The operation unit 2 is disposed on the upper surface of the top panel 12 of the housing 1. The operation unit 2 includes buttons 21 to 23 which can be pressed by the user.

[0022] The operation unit 2 outputs a first command to the control unit 7 each time the user operates (presses) the button 21. When the control unit 7 receives the first command while the operation of the blower 100 is stopped, the control unit 7 executes a startup process to start (start) the operation of the blower 100. Furthermore, when the control unit 7 receives the first command while the blower 100 is operating, the control unit 7 executes an operation mode switching process to alternately switch the operation mode of the blower 100 between the air blowing mode and the hot air mode. In other words, when the button 21 is operated while the blower 100 is operating in the air blowing mode, the operation mode of the blower 100 is switched to the hot air mode, and when the button 21 is operated while the blower 100 is operating in the hot air mode, the operation mode of the blower 100 is switched to the air blowing mode.

[0023] In this embodiment, when the operation of the fan 100 is stopped and then the button 21 is operated to resume the operation of the fan 100, the operation mode of the fan 100 when the operation was last stopped is maintained as the operation mode of the fan 100. For example, when the operation of the fan 100 is stopped while the fan 100 is operating in the fan mode and then the button 21 is operated to resume the operation of the fan 100, the operation mode of the fan 100 becomes the fan mode.

[0024] Operation unit 2 outputs a second command to control unit 7 every time button 22 is operated (pressed) by the user. When control unit 7 receives the second command while fan 100 is in operation, it executes a stop process to stop the operation of fan 100.

[0025] The operation unit 2 outputs a third command to the control unit 7 each time the user operates (presses) the button 23. When the control unit 7 acquires the third command while the blower 100 is operating, the control unit 7 executes an air volume switching process to switch the air volume of the blower 100 to "weak", "medium", "strong" and "automatic" in sequence. That is, when the button 23 is operated while the blower 100 is operating with the air volume of "weak", the air volume of the blower 100 is switched to "medium", and when the button 23 is operated while the blower 100 is operating with the air volume of "medium", the air volume of the blower 100 is switched to "strong". When the button 23 is operated while the blower 100 is operating with the air volume of "strong", the air volume of the blower 100 is switched to "automatic", and when the button 23 is operated while the blower 100 is operating with the air volume of "automatic", the air volume of the blower 100 is switched to "weak".

[0026] The air intake 31 (see FIG. 2) is a plurality of holes (openings) for taking in air into the housing 1, and is formed in the back panel 14 in this embodiment. That is, the air intake 31 is formed on the back surface of the housing 1. The air intake 31 is made up of a plurality of holes penetrating the back panel 14 in the front-rear direction D3. Each of the plurality of holes in the air intake 31 is formed in a substantially rectangular shape having a length in the up-down direction D1, and has an opening area large enough to prevent a user's finger from entering. In this embodiment, the air intake 31 is formed in substantially the entire back surface of the back panel 14 so that as much air as possible is taken in the housing 1.

[0027] The air outlet 32 ​​(see FIG. 1) is a hole (opening) for blowing air out of the housing 1, and is provided in the body 4 housed in the housing 1. In this embodiment, a pair (two) of air outlets 32 are provided to correspond to each gap between the front panel 13 and the two side panels 15, 16. One of the pair of air outlets 32 is located between the left end of the front panel 13 and the front end of the side panel 15, and the other air outlet 32 ​​is located between the right end of the front panel 13 and the front end of the side panel 16. Each of the pair of air outlets 32 has a vertically elongated opening extending along the up-down direction D1 and is open toward the front. However, the number of air outlets 32 is at least one, and is not limited to two, and may be one or three or more.

[0028] The pair of fans 33 and 34, the pair of filters 35 and 36, the inner cover 17, the body 4, the discharge device 5, and the pair of heat sources 37 and 38 are housed within the housing 1.

[0029] As shown in FIG. 3, the inner cover 17 is disposed inside the housing 1 at a position facing at least the back panel 14. FIG. 3 is an exploded perspective view of the blower 100 with the back panel 14 removed, viewed obliquely from the left rear. In other words, the inner cover 17 is disposed in front of the back panel 14. The inner cover 17 is formed with an air vent 171 for passing air taken in from the air inlet 31 of the back panel 14. Here, the back panel 14 is removably attached to the inner cover 17. Therefore, only the back panel 14 of the housing 1 can be removed by separating it from the other panels (the bottom panel 11, the top panel 12, the front panel 13, and the pair of side panels 15, 16).

[0030] As shown in Fig. 4, the body 4 is disposed inside the housing 1 and in front of the inner cover 17. Fig. 4 is a perspective view of the blower 100 viewed diagonally from the left rear with the back panel 14, the pair of filters 35, 36, the lid body 50, and the inner cover 17 removed. The inner cover 17 is fixed to the body 4 so as to cover the back surface of the body 4. The body 4 has air passages 41, 42 for guiding air taken in through the air intake 31 to the air outlet 32.

[0031] In this embodiment, a pair (two) of air passages 41, 42 are provided in the body 4 to correspond to the pair of air outlets 32. The air passage 41 leading to the air outlet 32 ​​on the right side of the front panel 13 is disposed at the right end of the body 4, and the air passage 42 leading to the air outlet 32 ​​on the left side of the front panel 13 is disposed at the left end of the body 4. In other words, air taken in from the air intake 31 passes through the pair of air passages 41, 42 provided in the body 4 and is blown out of the housing 1 from the pair of air outlets 32. The air passages 41, 42 will be described in detail in the section "[2] Air passages".

[0032] As shown in FIG. 4, the pair of fans 33, 34 are provided on the back surface of the body 4. Each of the pair of fans 33, 34 is a double-suction type centrifugal fan. The pair of fans 33, 34 are arranged at both ends of the body 4 in the vertical direction D1 so as to be spaced apart from each other in the vertical direction D1. In this embodiment, the fan 33 is arranged at the lower end of the body 4, and the fan 34 is arranged at the upper end of the body 4, so that the fan 34 is arranged relatively above the fan 33. The pair of fans 33, 34 are arranged inside (in front of) the inner cover 17. Therefore, when the inner cover 17 is removed, the pair of fans 33, 34 are exposed to the rear.

[0033] The pair of fans 33, 34 generate airflow by sending air into a pair of air passages 41, 42 provided in the body 4. That is, the pair of fans 33, 34 are provided at the end (upstream end) of the pair of air passages 41, 42 opposite to the air outlet 32, and generate airflow (wind) that is blown out from the air outlet 32 ​​through the pair of air passages 41, 42. In this embodiment, the lower fan 33 is disposed at the upstream end of the air passage 41 on the right side of the body 4, and the upper fan 34 is disposed at the upstream end of the air passage 42 on the left side of the body 4. As a result, the airflow generated by the operation of the fan 33 is blown out from the air outlet 32 ​​on the right side of the front panel 13 through the air passage 41. On the other hand, the airflow generated by the operation of the fan 34 is blown out from the air outlet 32 ​​on the left side of the front panel 13 through the air passage 42.

[0034] Each of the pair of filters 35, 36 (see FIG. 3) is, for example, a dust filter or a deodorizing filter. The dust filter can collect dust, pollen, smoke, and fine particulate matter (PM2.5, for example). The deodorizing filter can remove odors from the air. In this embodiment, the pair of filters 35, 36 each have a thin, approximately rectangular parallelepiped shape in the front-rear direction D3, and are disposed adjacent to each other in the up-down direction D1. The pair of filters 35, 36 are disposed on the inside (front) of the back panel 14 and behind the inner cover 17 so as to be sandwiched between the back panel 14 and the inner cover 17. Therefore, when the back panel 14 is removed, the pair of filters 35, 36 are exposed to the rear.

[0035] The discharge device 5 has an electrode holding surface 53 (see FIG. 10) on which a first discharge electrode 51 (see FIG. 10) and a second discharge electrode 52 (see FIG. 10) are provided. The discharge device 5 has an induction electrode in addition to the first discharge electrode 51 and the second discharge electrode 52. When a voltage (high voltage) is applied between the first discharge electrode 51 and the second discharge electrode 52 and the induction electrode, the discharge device 5 generates positive ions and negative ions as discharge products by generating discharges between the first discharge electrode 51 and the second discharge electrode 52 and the induction electrode.

[0036] The discharge device 5 is attached to the body 4 at a position facing at least one of the pair of air passages 41, 42. In other words, in this embodiment, the body 4 constitutes a "discharge device holding member" that holds the discharge device 5. The discharge device 5 is attached to the body 4 such that at least the first discharge electrode 51 and the second discharge electrode 52 are exposed in the air passage 41. As a result, discharge products (positive ions and negative ions) generated by the discharge device 5 are carried by the air current passing through the air passage 41 and are discharged outside the housing 1 from the air outlet 32. The discharge device 5 will be described in detail in the section "[3] Discharge device and discharge device holding member".

[0037] The pair of heat sources 37, 38 are each composed of a heater that generates heat when electricity is applied. When electricity is applied to each of the heat sources 37, 38, the heat sources 37, 38 convert electric energy into thermal energy and generate heat. The pair of heat sources 37, 38 are disposed in a pair of air passages 41, 42 of the body 4. As a result, when electricity is applied to the pair of heat sources 37, 38, the heat generated by the pair of heat sources 37, 38 heats the airflow passing through the pair of air passages 41, 42, and the heated air is blown out of the housing 1 through the air outlet 32.

[0038] As shown in FIG. 5, the control unit 7 is electrically connected to the pair of fans 33, 34, the discharge device 5, the pair of heat sources 37, 38, and the operation unit 2. The control unit 7 mainly comprises a computer system having one or more processors such as a CPU (Central Processing Unit) and one or more memories such as a ROM (Read Only Memory) and a RAM (Random Access Memory), and executes various processes (information processing). As described above, the control unit 7 controls each part of the blower 100 in response to the operation of the operation unit 2. Specifically, when starting the operation of the blower 100, the control unit 7 operates the pair of fans 33, 34 and the discharge device 5 regardless of whether the blower 100 is in the air blowing mode or the hot air mode. In addition, when the blower 100 is operating in the air blowing mode, the control unit 7 operates the pair of heat sources 37, 38. Furthermore, the control unit 7 controls the airflow (rotation speed) of the pair of fans 33, 34 in response to the airflow.

[0039] As described above, the blower 100 according to this embodiment includes the discharge device 5 held in the body 4 so as to be exposed in one of the pair of air passages 41, 42, the fan 33 that sends air into the air passage 41. As a result, when the fan 33 and the discharge device 5 are in operation, the air blown out from the air outlet 32 ​​on the right side of the front panel 13 through the air passage 41 contains discharge products (positive ions and negative ions) generated by the discharge device 5. In other words, the blower 100 according to this embodiment is an example of an electric device that includes a discharge device holding member (body 4) that holds the discharge device 5, and an airflow generating device (fan 33) that generates an airflow that passes through the air passage 41.

[0040] [2] Wind path Next, a specific configuration of the air passage of the fan 100 according to this embodiment will be described with reference to FIGS.

[0041] 6 to 9, the housing 1 and the inner cover 17 are omitted, and the blower 100 is shown in a state in which the body 4 is exposed. Also, Figs. 6 and 7 are schematic diagrams of the blower 100 cut along the line A3-A3 in Fig. 9. Fig. 8 is a schematic diagram of the blower 100 cut along the line A1-A1 in Fig. 7, and Fig. 9 is a schematic diagram of the blower 100 cut along the line A2-A2 in Fig. 7. However, in these drawings, hatching of the cut surfaces is omitted.

[0042] As shown in Fig. 6 and Fig. 7, a space surrounded by walls inside the body 4 constitutes a pair of air passages 41, 42. Each of the pair of air passages 41, 42 has a length in the up-down direction D1. When the fan 33 connected to the air passage 41 is operated, air sucked in from the air intake 31 is sent from the upstream end (lower end) of the air passage 41 into the air passage 41, passes through the right end (air passage 41) of the body 4, and is blown out from the air outlet 32 ​​on the right side of the front panel 13. Similarly, when the fan 34 connected to the air passage 42 is operated, air sucked in from the air intake 31 is sent from the upstream end (upper end) of the air passage 42 into the air passage 42, passes through the left end (air passage 42) of the body 4, and is blown out from the air outlet 32 ​​on the left side of the front panel 13.

[0043] 6 and 7, one air passage 41 of the pair of air passages 41, 42 is divided into a first air passage 411 and a second air passage 412 by an inner wall 410. The inner wall 410 has a length in the longitudinal direction of the air passage 41 (the up-down direction D1), and divides the air passage 41 into the first air passage 411 and the second air passage 412 in the left-right direction D2. In this embodiment, the first air passage 411 is located to the right as viewed from the inner wall 410, and the second air passage 412 is located to the left as viewed from the inner wall 410.

[0044] Heat source 37 is disposed in first air passage 411 of one air passage 41, and heat source 38 is disposed in the other air passage 42. Therefore, when fan 33 and heat source 37 are operated, air passing through air passage 41 is heated by heat source 37, and warm air is blown out from air outlet 32 ​​on the right side of front panel 13. Similarly, when fan 34 and heat source 38 are operated, air passing through air passage 42 is heated by heat source 38, and warm air is blown out from air outlet 32 ​​on the left side of front panel 13.

[0045] Furthermore, at least the first discharge electrode 51 and the second discharge electrode 52 of the discharge device 5 are disposed in the second air passage 412 of the air passage 41 (see FIG. 9). Therefore, when the fan 33 and the discharge device 5 are operated, the discharge products (positive ions and negative ions) generated in the discharge device 5 are carried by the airflow passing through the air passage 41 and are blown out from the air outlet 32 ​​on the right side of the front panel 13.

[0046] The downstream end of each of the pair of air passages 41, 42 continues to air outlet 32, which opens forward. Air outlet 32 ​​is provided with a plurality of louvers 321, as shown in Figs. 8 and 9. The plurality of louvers 321 are configured to be capable of swinging in the up-down direction D1 by rotating about a rotation axis along the left-right direction D2. Therefore, blower 100 can adjust the direction of air (wind) blown out from air outlet 32 ​​in the up-down direction D1 by adjusting the orientation of the plurality of louvers 321.

[0047] Each of the air passages 41, 42 has a curved shape in a plane perpendicular to the left-right direction D2. That is, air is sent into each of the air passages 41, 42 from one end in the up-down direction D1 by operating the fans 33, 34, and the air is blown forward from the air outlet 32 ​​that opens forward.

[0048] For example, in air passage 41, as shown in Fig. 8 and Fig. 9, air sent from the lower end is blown out from air outlet 32 ​​that opens forward. In Fig. 8 and Fig. 9, the air flow is indicated by white arrows. Thus, air passage 41 has a shape that extends (upward) from the upstream end (lower end) along the vertical direction D1, with its tip curved forward, in a (left) side view. Similarly, air passage 42 has a shape that extends (downward) from the upstream end (upper end) along the vertical direction D1, with its tip curved forward, in a side view.

[0049] 8 and 9, a straightening member 413 for smoothly passing airflow is disposed at least in second air passage 412 of air passage 41. Straightening member 413 functions as a straightening plate for suppressing the generation of turbulence. In this embodiment, straightening member 413 is disposed approximately in the center of air passage 41 in the width direction, and has a shape that curves along air passage 41. Specifically, straightening member 413 is a rib-shaped member that protrudes leftward from the right side surface of second air passage 412, and divides second air passage 412 in the width direction.

[0050] [3] Discharge device and discharge device holding member Next, the specific configurations of the discharge device 5 and the discharge device holding member (body 4) of the blower 100 according to this embodiment will be described with reference to Figs.

[0051] As shown in FIG. 10, the discharge device 5 has a first discharge electrode 51 (positive discharge electrode), a second discharge electrode 52 (negative discharge electrode), an electrode holding surface 53, an electrode substrate 54, a case 55, an electrode protection section 56, a partition wall 57, a guide rib 58 and a handle 59.

[0052] The case 55 is made of an electrically insulating resin and has, for example, a rectangular parallelepiped (box-like) shape having a length in the up-down direction D1. The case 55 accommodates an electrode board 54, a circuit board, etc. One surface of the case 55 (the right side surface in this embodiment) constitutes an electrode holding surface 53. The electrode holding surface 53 has holes formed therein for exposing at least the first discharge electrode 51 and the second discharge electrode 52.

[0053] The electrode substrate 54 is provided with a first discharge electrode 51 and a second discharge electrode 52 protruding in the normal direction from one surface (the right side surface in this embodiment) of the electrode substrate 54. In this embodiment, as an example, the first discharge electrode 51 and the second discharge electrode 52 are electrodes with brush-shaped tips. The first discharge electrode 51 and the second discharge electrode 52 protrude from one surface of the electrode substrate 54 at the same height position and are arranged side by side in the up-down direction D1 with a gap therebetween. In addition, around the first discharge electrode 51 and the second discharge electrode 52 on one surface of the electrode substrate 54, an induction electrode electrically insulated from the first discharge electrode 51 and the second discharge electrode 52 is provided.

[0054] The circuit board has a discharge voltage supply circuit that generates positive and negative high voltages, etc. The voltage generated by the discharge voltage supply circuit is supplied to the first discharge electrode 51, the second discharge electrode 52, and the induction electrode. Specifically, the discharge voltage supply circuit applies a high-voltage positive pulse to the first discharge electrode 51 and a high-voltage negative pulse to the second discharge electrode 52, thereby applying a voltage that generates a discharge between the induction electrode and the first discharge electrode 51 and between the induction electrode and the second discharge electrode 52.

[0055] The electrode protection part 56 is disposed around the first discharge electrode 51 and the second discharge electrode 52 on the electrode holding surface 53. In this embodiment, the electrode protection part 56 is formed integrally with the case 55, and protrudes from the electrode holding surface 53 in the same direction (rightward) as the first discharge electrode 51 and the second discharge electrode 52. The height of the electrode protection part 56 is greater than the height of the tips of the first discharge electrode 51 and the second discharge electrode 52.

[0056] The electrode protection part 56 is made of a pair of frame-shaped members located on both sides in the front-rear direction D3 of each of the first discharge electrode 51 and the second discharge electrode 52. Specifically, the electrode protection part 56 is made of a hollow frame inside which the first discharge electrode 51 and the second discharge electrode 52 are located when viewed from behind. However, the shape of the electrode protection part 56 is not limited to the shape shown in Fig. 10 etc.

[0057] The partition wall 57 is made of an electrically insulating resin. The partition wall 57 is provided between the first discharge electrode 51 and the second discharge electrode 52 in a first direction (vertical direction D1 in this embodiment) in which the first discharge electrode 51 and the second discharge electrode 52 are arranged so as to divide the space between the first discharge electrode 51 and the second discharge electrode 52. In this embodiment, the partition wall 57 is formed integrally with the case 55 and protrudes from the electrode holding surface 53 in the same direction (rightward) as the first discharge electrode 51 and the second discharge electrode 52. The height of the partition wall 57 is higher than the height of the tips of the first discharge electrode 51 and the second discharge electrode 52.

[0058] The guide rib 58 is a member that protrudes forward from the front surface of the case 55. In this embodiment, a pair (two) of guide ribs 58 are provided lined up in the up-down direction D1, and each guide rib 58 has a length in the up-down direction D1. The handle 59 is a member that protrudes rearward from the back surface of the case 55. In this embodiment, the handle 59 has a length in the left-right direction D2. The pair of guide ribs 58 and the handle 59 are formed integrally with the case 55.

[0059] The discharge device 5 is removably attached to the body 4 serving as a discharge device holding member. That is, the discharge device 5 and the body 4 are separate entities, and the discharge device holding member (body 4) holds the discharge device 5 in a removably state. Therefore, for example, by removing the discharge device 5 from the body 4, maintenance (including inspection, replacement, repair, etc.) of the discharge device 5 can be easily performed. Specifically, in this embodiment, the discharge device 5 is attached to a position accessible from the back side of the body 4 in a state in which the back panel 14, the pair of filters 35, 36, and the lid body 50 are removed (see FIG. 3). Therefore, by removing the back panel 14, the pair of filters 35, 36, and the lid body 50, the discharge device 5 can be attached to and detached from the discharge device holding member (body 4).

[0060] In the present embodiment, the discharge device 5 has a first connector 501 electrically connected to the electrode board 54 and the circuit board, etc. The first connector 501 is disposed at the lower end of the case 55. The first connector 501 is removably coupled to the second connector 502 held by the body 4. When the first connector 501 and the second connector 502 are coupled, the first connector 501 and the second connector 502 are electrically connected, and the discharge device 5 is electrically connected to the control unit 7, etc. In the present embodiment, as an example, the first connector 501 and the second connector 502 are plug-in connectors that are detachable along the up-down direction D1. Therefore, the first connector 501 and the second connector 502 can be coupled (electrically connected) to each other by sliding the first connector 501 downward from a position facing the second connector 502.

[0061] Here, the body 4 serving as a discharge device holding member includes a guide structure 43 that guides the sliding movement of the discharge device 5 when the discharge device 5 is attached or detached, as shown in Fig. 11. Fig. 11 is a rear view showing the periphery of the portion of the body 4 where the discharge device 5 is attached (the portion covered by the lid body 50), with the discharge device 5 indicated by an imaginary line (two-dot chain line). In this embodiment, the guide structure 43 includes a pair (two) of grooves 431 aligned in the up-down direction D1.

[0062] When attaching the discharge device 5 to the body 4, the user removes the lid 50 and attaches the discharge device 5 from the back side (rear). Specifically, the user first holds the handle 59 of the discharge device 5 and moves the discharge device 5 forward so that the pair of guide ribs 58 are inserted into the pair of grooves 431, respectively. Then, with the pair of guide ribs 58 inserted into the pair of grooves 431, the user operates the discharge device 5 to slide it so that the pair of guide ribs 58 move within the pair of grooves 431, respectively.

[0063] That is, the user operates the discharge device 5 by sliding it downward, then diagonally downward to the right, and finally downward, as shown by the arrow Op1 in Fig. 11. At this time, the first discharge electrode 51 and the second discharge electrode 52 of the discharge device 5 are introduced into the second air passage 412 from an opening 414 (see Fig. 13) formed on the right side surface (right wall) of the second air passage 412. Furthermore, the first connector 501 of the discharge device 5 is inserted into the second connector 502 and coupled (electrically connected).

[0064] When removing the discharge device 5 from the body 4, the user slides the discharge device 5 in the direction opposite to the arrow Op1, and finally moves the discharge device 5 backward to remove the discharge device 5. At this time, the first connector 501 of the discharge device 5 is separated from the second connector 502, and the first discharge electrode 51 and the second discharge electrode 52 of the discharge device 5 are retracted from within the second air passage 412.

[0065] In this way, the discharge device holding member (body 4) is provided with the guide structure 43, which makes it easy to attach and detach the discharge device 5 to and from the discharge device holding member (body 4). In particular, since the movement direction of the discharge device 5 is restricted, it becomes easier to introduce the first discharge electrode 51 and the second discharge electrode 52 into the second air passage 412 without hitting the body 4 or the like, and it becomes easier to insert the first connector 501 of the discharge device 5 into the second connector 502.

[0066] In the fan 100 according to this embodiment, the body 4 serving as a discharge device holding member has the configuration described below.

[0067] That is, as shown in Figs. 12 and 13, the discharge device holding member (body 4) according to this embodiment is a member for holding the discharge device 5 having the electrode holding surface 53 on which the first discharge electrode 51 and the second discharge electrode 52 are provided, and includes an air passage forming surface 44 and a partitioning portion 45. The air passage forming surface 44 faces the electrode holding surface 53, and forms an air passage 41 (a second air passage 412) between the electrode holding surface 53 and the partitioning portion 45. The partitioning portion 45 protrudes from the air passage forming surface 44, and separates the first space Sp1 including the first discharge electrode 51 from the second space Sp2 including the second discharge electrode 52 in the air passage 41. Fig. 12 is an enlarged view of the area Z1 in Fig. 9, and Fig. 13 is an enlarged view of the area Z1 in Fig. 7. In Fig. 12, the air flow is indicated by an outline arrow.

[0068] In the present disclosure, "partition" means to put some kind of partition between two continuous spaces, and includes not only completely separating the two spaces but also loosely separating the two spaces while they are connected. In other words, the partition 45 may completely separate the first space Sp1 and the second space Sp2, or may be structured to partially separate the first space Sp1 and the second space Sp2 by being present between the first space Sp1 and the second space Sp2 as shown in Figs. 12 and 13.

[0069] 13, in this embodiment, the left side surface (surface facing second air passage 412) of inner wall 410 that separates first air passage 411 and second air passage 412 constitutes air passage forming surface 44. In other words, when discharge device 5 is held by the discharge device holding member (body 4), second air passage 412 for passing airflow is formed between the left side surface of inner wall 410 and electrode holding surface 53 of discharge device 5. Partitioning portion 45 is formed so as to protrude from air passage forming surface 44 that is the left side surface of inner wall 410. Partitioning portion 45 is formed integrally with inner wall 410 that is a part of body 4.

[0070] As described above, by separating the first space Sp1 and the second space Sp2 with the partition 45, it is easy to suppress a decrease in the discharge products caused by recombination of the discharge products (positive ions) generated by the first discharge electrode 51 and the discharge products (negative ions) generated by the second discharge electrode 52. Moreover, since the partition 45 is provided on the air passage forming surface 44 of the discharge device holding member (body 4), it is possible to provide the partition 45 having a size and shape sufficient to separate the first space Sp1 and the second space Sp2 while miniaturizing the discharge device 5 itself. In other words, even if a sufficient partition wall 57 cannot be secured for reasons such as miniaturization of the discharge device 5, the partition 45 makes it easy to suppress recombination of the discharge products (positive ions) generated by the first discharge electrode 51 and the discharge products (negative ions) generated by the second discharge electrode 52 of the discharge device 5.

[0071] Furthermore, by providing the partition portion 45 on the air passage forming surface 44 facing the electrode holding surface 53, the first space Sp1 and the second space Sp2 can be separated on the tip side of the first discharge electrode 51 and the second discharge electrode 52, and recombination of the discharge products can be efficiently suppressed. As a result, according to the discharge device holding member (body 4) of this embodiment, it is possible to provide a discharge device holding member and an electric device (blower 100) that can easily suppress recombination of the discharge products due to the first discharge electrode 51 and the discharge products due to the second discharge electrode 52.

[0072] To explain in more detail, in this embodiment, the air passage 41 passes the airflow in a second direction (front-rear direction D3) intersecting with the first direction (up-down direction D1) in which the first discharge electrode 51 and the second discharge electrode 52 are aligned. The partition portion 45 has a length along the second direction. That is, as shown in FIG. 12, the partition portion 45 has a length in the second direction (front-rear direction D3 in this embodiment) in which the airflow passes at least between the first discharge electrode 51 and the second discharge electrode 52. This makes it difficult for the airflow passing through the air passage 41 (second air passage 412) to mix between the first space Sp1 side and the second space Sp2 side, which makes it easier to suppress recombination between the discharge product (positive ions) by the first discharge electrode 51 and the discharge product (negative ions) by the second discharge electrode 52.

[0073] In this embodiment, as described above, the body 4 includes the rectifying member 413 disposed upstream of the electrode holding surface 53 in the air passage 41 (second air passage 412). Here, the partition 45 is located on an extension line of the rectifying member 413 as shown in FIG. 12. That is, the partition 45 separating the first space Sp1 and the second space Sp2 is disposed on an extension line of the rectifying member 413 extended downstream (toward the air outlet 32). This makes it possible to suppress turbulence of the airflow caused by the partition 45 and to suppress an increase in resistance to the airflow caused by providing the partition 45.

[0074] In this embodiment, as described above, the air passage 41 has a shape curved in a plane perpendicular to the left-right direction D2. Therefore, as shown in FIG. 12, the body 4 is disposed upstream (toward the fan 33) of the electrode holding surface 53 in the air passage 41 (second air passage 412), and includes a curved air passage 415 that curves in a plane including the first direction (up-down direction D1) and the second direction (front-back direction D3). Due to a difference in flow speed between the inner circumference side and the outer circumference side of the curved air passage 415, turbulence is likely to occur downstream as viewed from the curved air passage 415. Therefore, the effect of suppressing recombination of the discharge product (positive ions) by the first discharge electrode 51 and the discharge product (negative ions) by the second discharge electrode 52 of the discharge device 5 due to the provision of the partition portion 45 becomes significant.

[0075] As described above, the discharge device 5 has the partition wall 57 protruding from between the first discharge electrode 51 and the second discharge electrode 52 on the electrode holding surface 53. As a result, the first space Sp1 and the second space Sp2 are partitioned not only by the partition portion 45 provided in the discharge device holding member (body 4) but also by the partition wall 57. This makes it easier to suppress recombination of the discharge product (positive ions) by the first discharge electrode 51 and the discharge product (negative ions) by the second discharge electrode 52.

[0076] 12, it is preferable that at least a portion of the partition 45 faces the partition 57 in a direction perpendicular to the electrode holding surface 53. In the example of FIG. 12, only the rear end of the partition 45 faces the partition 57 in the left-right direction D2. However, it is sufficient that at least a portion of the partition 45 faces the partition 57, and the entire partition 45 may face the partition 57 in the left-right direction D2. With this configuration, the partition 45 and the partition 57 cooperate to easily suppress recombination of the discharge product (positive ions) of the first discharge electrode 51 and the discharge product (negative ions) of the second discharge electrode 52.

[0077] In this embodiment, as shown in FIG. 13, there is a gap G1 between the partition 45 and the partition wall 57 in a direction perpendicular to the electrode holding surface 53. In other words, the sum (L1+L2) of the height L1 (projection amount from the air passage forming surface 44) of the partition 45 and the height L2 (projection amount from the electrode holding surface 53) of the partition wall 57 is smaller than the distance L3 between the air passage forming surface 44 and the electrode holding surface 53. It is sufficient to have such a gap G1 between the partition 45 and the partition wall 57 when viewed from the side, and it is not essential that at least a part of the partition 45 and the partition wall 57 face each other. With this configuration, interference between the partition 45 and the partition wall 57 can be suppressed, and for example, attachment and detachment of the discharge device 5 is less likely to be hindered.

[0078] Furthermore, in this embodiment, height L1 of partition 45 is a height that does not interfere with discharge device 5. In other words, height L1 of partition 45 (protrusion amount from air passage forming surface 44) is restricted to a height that does not interfere with discharge device 5 introduced into air passage 41 (second air passage 412). With this configuration, interference between partition 45 and discharge device 5 can be suppressed, and, for example, attachment and detachment of discharge device 5 is less likely to be hindered.

[0079] [4] Variations Below, we will list some modified examples of the embodiment 1. The modified examples explained below can be applied in appropriate combinations.

[0080] An electrical device equipped with a discharge device holding member and an airflow generating device is not limited to the blower 100, but may be, for example, an air purifier, a heater, a cooling device, an air cooler, an electric fan, a circulator, a refrigerator, or a combination of these.

[0081] Furthermore, it is not essential that the discharge device 5 generates positive and negative ions, and for example, discharge products other than ions may be generated by the discharge of the first discharge electrode 51 and the second discharge electrode 52. Furthermore, it is not essential that the discharge device 5 has an induction electrode.

[0082] Further, the discharge device 5 has one each of the first discharge electrode 51 and the second discharge electrode 52, but may have multiple each. The shapes of the first discharge electrode 51 and the second discharge electrode 52 are not limited to brush shapes and may be, for example, pin-shaped (needle-shaped) or the like.

[0083] Furthermore, the discharge device holding member is not limited to the body 4, but may be, for example, a member separate from the body 4, or may be the housing 1 or the like.

[0084] The partition portion 45 is not limited to a configuration having a length along the second direction (front-rear direction D3), and may be, for example, a pin-shaped (needle-shaped) member or the like.

[0085] (Embodiment 2) 14, a fan 100A according to this embodiment differs from the first embodiment in the height L1 of a partition 45. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted as appropriate.

[0086] In this embodiment, the tip of the partition 45 is located within the range of the height L4 of the first discharge electrode 51. In other words, the sum (L1+L4) of the height L1 of the partition 45 (amount of protrusion from the air passage forming surface 44) and the height L4 of the first discharge electrode 51 (amount of protrusion from the electrode holding surface 53) is greater than the distance L3 between the air passage forming surface 44 and the electrode holding surface 53. As a result, the tip of the partition 45 overlaps with the first discharge electrode 51 in the left-right direction D2. According to this configuration, the effect of suppressing recombination of the discharge product (positive ions) by the first discharge electrode 51 of the discharge device 5 and the discharge product (negative ions) by the second discharge electrode 52 due to the provision of the partition 45 becomes significant.

[0087] The configuration of the second embodiment can be adopted in appropriate combination with the various configurations (including modified examples) described in the first embodiment.
