Description

  The present invention relates to a desktop type blower.

  2. Description of the Related Art Conventionally, a desktop type blower includes a housing in which a blower fan and a motor that rotates the blower fan are arranged. A suction port and a blower outlet are formed in the housing. When the blower fan is driven, air is sucked from the suction port, and air is blown from the blower port. In order to rotate the blower fan, it is necessary to supply electric power to the motor.

  The power supply may be performed using a power cord. In that case, one end of the power cord is connected to a terminal portion provided in the blower, and the other end is connected to an external power source such as a commercial power source. By the way, as a connection method between the one end of the power cord and the terminal portion, a magnet method or an insertion method can be considered. In the magnet system, a magnet plug provided at one end of the power cord is detachably connected to a plug receiver provided in the blower (see Patent Document 1). In the insertion method, an insertion plug provided at one end of the power cord is detachably connected to a plug receiver provided in the blower.

JP 2003-97830 A

  In the magnet system, there is a problem that the magnet plug falls from the plug receptacle when a person or an object contacts the magnet plug. On the other hand, in the insertion method, dropout due to contact is unlikely to occur, but there is a problem that if the insertion plug is not firmly inserted into the plug receptacle, contact failure occurs and the blower does not operate normally.

  An object of this invention is to provide the air blower which can prevent the occurrence of the poor contact at the time of use easily.

  In order to achieve the above object, the present invention provides a blower installed on a mounting surface in which a blower fan is arranged in a housing having an intake port and a blower opening, and an installation portion provided on one surface of the housing contacts. A power cord that has a plug at one end and supplies power; and a terminal portion that is provided on one surface of the housing and is detachably inserted and faces the installation surface. When the installation portion and the plug are in contact with each other, the plug and the terminal portion are electrically connected.

  According to this configuration, when the installation portion and the plug are in contact with the installation surface, the plug and the terminal portion are electrically connected. The state where the installation part and the plug are not in contact with the installation surface is a state where the blower is installed on the installation surface in an unstable state. That is, since the plug and the terminal portion are electrically connected when the blower is stably installed on the installation surface, it is possible to easily grasp the conductive state between the plug and the terminal portion. Also, even if the plug is not fully inserted into the terminal part and the installation part and the plug are not in contact with the installation surface, the installation part and plug are applied to the installation surface by applying force to the housing. By making contact, the plug and the terminal portion are electrically connected. Therefore, the plug and the terminal portion can be easily conducted without directly touching the plug.

  Further, the present invention is the air blower configured as described above, further comprising a plate portion that is attachable to and detachable from the housing, wherein the plug is inserted into the terminal portion through an insertion hole that opens to the plate portion. It is desirable that the plug is detachably formed by detaching the plug.

  According to this configuration, the plug is connected to the terminal portion through the insertion hole that opens in the plate portion that is detachable from the housing. Further, since the plate portion is formed to be detachable by detaching the plug, it is necessary to remove the plug from the terminal portion in order to remove the plate portion from the housing. That is, when the plate portion is removed, power is not supplied to the blower, and therefore, when the user removes the plate portion and cleans the inside of the housing, the user does not get an electric shock by touching various electronic components.

  According to the present invention, in the air blower configured as described above, a charged particle generating element that generates charged particles is provided, the plate portion is formed to be detachable by detaching the plug, and the charging portion is removed when the plate portion is removed. It is desirable that the particle generating element can be attached and detached.

  According to this configuration, since the charged particle generating element can be detached from the bottom surface of the casing when the plate portion is removed, the charged particle generating element can be easily replaced or cleaned.

  According to the present invention, in the air blower configured as described above, a filter facing the suction port is provided, the plate portion is formed to be detachable by detaching the plug, and the filter is attached and detached when the plate portion is removed. It is desirable to be able to do it.

  According to this configuration, since the filter can be detached from the bottom surface of the housing when the plate portion is removed, the filter can be easily replaced or cleaned.

  According to the present invention, when the installation portion and the plug are in contact with the installation surface, the plug and the terminal portion are electrically connected. The state where the installation part and the plug are not in contact with the installation surface is a state where the blower is installed on the installation surface in an unstable state. That is, since the plug and the terminal portion are electrically connected when the blower is stably installed on the installation surface, it is possible to easily grasp the conductive state between the plug and the terminal portion. Also, even if the plug is not fully inserted into the terminal part and the installation part and the plug are not in contact with the installation surface, the installation part and plug are applied to the installation surface by applying force to the housing. By making contact, the plug and the terminal portion are electrically connected. Therefore, the plug and the terminal portion can be easily conducted without directly touching the plug.

  Embodiments of the present invention will be described below with reference to the drawings. 1, 2, 3, and 4 show a top view, a bottom view, a left side view, and a rear view of the blower according to the first embodiment. The blower device 1 includes a cubic housing 2, and a suction port 2 a (see FIG. 6) is opened on the left side surface of the housing 2, and an air outlet 2 b is opened on the upper surface. The blower outlet 2b is formed in a circular shape, and a wind direction plate 10 supported so as to be movable up and down with respect to the housing 2 is disposed to face the blower outlet 2b.

  The bottom plate 3 of the housing 2 is detachably provided, and rubber legs 4 are provided at the four corners of the bottom plate 3. Thereby, the air blower 1 can be installed and used on a desktop etc. Further, the rear surface of the housing 2 is provided with a hooking hole 2c that is hooked on a hook provided on a wall surface in the room. Thereby, the air blower 1 can also be hung on a wall surface and used.

  A power cord 5 is connected to the right end of the bottom surface of the housing 2. As will be described in detail later, the power cord 5 is connected by inserting a plug 6 provided at one end into a terminal portion 35 (see FIG. 6) through an insertion hole 3a (see FIG. 6) provided in the bottom plate 3. The other end of the power cord 5 is connected to a power supply source such as a commercial power source or a USB terminal to supply power to the blower 1.

  5 and 6 show a right side sectional view and a front sectional view of the blower 1. The wind direction plate 10 has a circular planar shape having substantially the same diameter as the air outlet 2b, and the lower surface 10a is formed in a substantially truncated cone shape having an inclined surface. A sleeve 11 is attached to the center of the wind direction plate 10. The sleeve 11 is fitted to a shaft portion 17 disposed on the housing 2, and can move up and down relative to the housing 2 together with the wind direction plate 10. The shaft portion 17 passes through a through hole 25d opened at the center of a light guide plate 25 described later, and is supported by a duct member 32 disposed in the housing 2.

  The shaft portion 17 is provided with first and second locking claws 17a and 17b arranged in the vertical direction, and a compression spring 16 for urging the wind direction plate 10 upward. An engagement member 12 that engages with the first and second locking claws 17 a and 17 b is attached in the sleeve 11. A power switch 18 is disposed on the upper surface of the duct member 32.

  The wind direction plate 10 urged by the compression spring 16 moves between a position where the air outlet 2b is opened and a position where the air outlet 2b is closed by the engagement of the first and second locking claws 17a, 17b and the engaging member 12. That is, as shown in the figure, when the engaging member 12 is engaged with the second locking claw 17b, the air outlet 2b is opened. At this time, the power switch 18 is turned on.

  When the airflow direction plate 10 is pushed down from the open state of the air outlet 2b and the engaging member 12 is engaged with the first locking claws 17a as shown in FIG. 7, the airflow direction plate 10 closes the air outlet 2b. At this time, the sleeve 11 contacts the power switch 18, and the power switch 18 is turned off. Moreover, if the wind direction board 10 is pushed down from the state which closed the blower outlet 2b, as shown in FIG. 5, the wind direction board 10 will pop up.

  Thereby, the power switch 18 is turned on and off by the vertical movement of the wind direction plate 10, and the blower fan 30, the ion generating element 40 and the LED 26 described later are driven when the power switch 18 is turned on. Further, when the air outlet 2b is opened, an annular outflow portion 8 is formed by which the airflow is radially sent out between the air outlet 2b and the wind direction plate 10 by the air direction plate 10 having substantially the same diameter as the air outlet 2b.

  The duct member 32 is disposed in the lower part of the housing 2 and is formed in a box shape having an opening surface at one end facing the suction port 2a. In the duct member 32, a blower fan 30 made of a sirocco fan covered with a casing 30a is disposed. The blower fan 30 is screwed and held on a fan holding portion 32a formed of the right side wall of the duct member 32.

  In the casing 30a, intake ports 30b and 30c are opened on both surfaces in the axial direction, and an exhaust port 30d is opened on an end surface in the circumferential direction. The duct member 32 forms the suction duct 20 that connects the suction port 2a and the one suction port 30b. A filter 23 detachable from the bottom surface of the housing 2 is disposed at the suction port 2a.

  The right side wall of the duct member 32 has an opening 32b facing the air inlet 30c, and a notch 32d (see FIG. 8) is provided at the right end on the back side. Further, a chamfer 32c (see FIG. 8) is applied to the bottom of the duct member 32 on the back side. On the right side of the duct member 32, a circuit board 34 on which electronic parts such as the terminal portion 35 are mounted is erected and disposed.

  The airflow flowing into the suction duct 20 from the suction port 2a by driving the blower fan is guided to the suction port 32b as indicated by an arrow A1. Further, as shown by an arrow A2 in the rear sectional view of FIG. 8, a part of the airflow flows out from the duct member 32 through the notch 32d and flows downward, and flows outside the chamfer 32c to the left. . The airflow flows upward between the circuit board 34 and the duct holding portion 32a, and is guided to the intake port 32c through the opening 32b.

  Thereby, air current can be sucked in from the both surfaces of the blower fan 30 in the axial direction through a plurality of paths, and the air blowing efficiency can be improved. Moreover, the electronic component mounted on the circuit board 34 can be cooled by the airflow. At this time, the opening 32 b is provided above the center of the blower fan 30 and faces the upper portion of the standing circuit board 34. Thereby, the cooling effect of the circuit board 34 by the airflow which distribute | circulates toward the opening part 32b from the downward direction can be improved.

  A first blowing duct 21 is provided in front of the exhaust port 30 d of the blower fan 30. Above the first outlet duct 21, a second outlet duct 22 that opens the outlet 2b is provided. The 1st blowing duct 21 and the 2nd blowing duct 22 are connected via the communicating port 25b of the light-guide plate 25 mentioned later.

  The upper part of the first blowing duct 21 is formed by a duct member 32, and the lower part is formed by a holding member 45 that holds the ion generating element 40 and is adjacent to the exhaust port 30d. FIG. 9 shows a perspective view of the holding member 45 holding the ion generating element 40. The holding member 45 has a bent portion 45a in which an opening 45b having substantially the same width in the left-right direction as the exhaust port 30d is opened at the rear end face and the flow path is widened in the left-right direction.

  The front wall 45c of the bent portion 45a is formed by a curved surface continuous with the lower end of the casing 30a of the blower fan 30, and is inclined to face the exhaust port 30d. As a result, the airflow is bent and guided upward through the bent portion 45a. At this time, the air flow sent out from the exhaust port 30b collides with the front wall 45c of the bent portion 45a, and the dynamic pressure is converted into a static pressure and decelerated. Further, the dynamic pressure is also converted to static pressure by the widening of the flow path by the bent portion 45a, and the airflow is further decelerated. Therefore, the bending part 45a comprises the static pressure conversion part which converts the dynamic pressure of an airflow into a static pressure.

  The front wall 45c of the bent portion 45a is provided with a partition plate 45d extending vertically in the center portion facing the opening portion 45b.

  The ion generating element 40 has a pair of needle-like discharge electrodes 41 arranged in parallel in the left-right direction facing the first blowing duct 21. The discharge electrode 41 is disposed immediately above the bent portion 45a, and the distance between both the discharge electrodes 41 is formed wider than the width of the opening 45b.

The discharge electrode 41 of the ion generating element 40 generates a corona discharge by applying a high voltage having an AC waveform or an impulse waveform. A positive voltage is applied to one of the discharge electrodes 41, and water molecules in the air are ionized by corona discharge to generate hydrogen ions. This hydrogen ion is clustered with water molecules in the air by solvation energy. As a result, positive ions of air ions composed of H ⁺ (H ₂ O) m (m is 0 or an arbitrary natural number) are released.

A negative voltage is applied to the other discharge electrode 41, and oxygen ions or water molecules in the air are ionized by corona discharge to generate oxygen ions. This oxygen ion is clustered with water molecules in the air by solvation energy. Thereby, negative ions of air ions composed of O ₂ ⁻ (H ₂ O) n (n is an arbitrary natural number) are released.

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. Accordingly, by sending positive ions and negative ions into the room from the air outlet 2b, the room can be sterilized and the odor can be removed.

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)

  By arranging the pair of discharge electrodes 41 in the left-right direction perpendicular to the airflow, it is possible to suppress the disappearance due to the collision between the positive ions and the negative ions and increase the amount of ions to be sent.

  In addition, since the discharge electrode 41 is disposed immediately above the bent portion 42a, ions generated at the discharge electrode 41 are included in the airflow that has been converted to static pressure by the bent portion 42a and decelerated. Thereby, the ion which generate | occur | produced in the discharge electrode 41 can be reliably conveyed with an airflow, and the sending amount of ion can be increased.

  At this time, since the distance between the discharge electrodes 41 is larger than the width of the opening 45b and the discharge electrodes 41 are arranged on both sides of the opening 45b, ions can be more reliably included in the decelerated airflow. . Moreover, the flow rate of the airflow flowing around each discharge electrode 41 can be made substantially equal by the partition plate 45d, and positive ions and negative ions can be contained uniformly.

  As shown in FIG. 10, the holding member 45 can be detached from the bottom surface of the housing 2 by removing the bottom plate 3. Thereby, the ion generating element 40 can be replaced | exchanged easily. In addition, the blade 30e (see FIG. 6) of the blower fan 30 can be cleaned through the exhaust port 30d exposed by the attachment and detachment of the holding member 45. Similarly, the filter 23 (see FIG. 6) can be detached from the bottom surface of the housing 2 by removing the bottom plate 3, and the filter 23 can be easily cleaned.

  The ion generating element 40 has a connection terminal 40a on the upper surface. When the ion generating element 40 is mounted together with the holding member 45 from below, the connection terminal 40 a comes into contact with the terminal portion 42 provided in the housing 2 so that power can be supplied to the ion generating element 40. For this reason, the weight of the ion generating element 40 is not weighted to the terminal part 42, and the failure of the terminal part 42 by continuing weighting can be prevented.

  The bottom plate 3 of the housing 2 can be removed with the plug 6 (see FIG. 6) of the power cord 5 removed as shown in the bottom view of FIG. Thereby, the electric shock by being energized when the bottom plate 3 is removed can be prevented.

  5 and 6, the light guide plate 25 is horizontally disposed on the upper surface of the first outlet duct 21. The light guide plate 25 is formed in a flat plate shape by a transparent member such as acrylic, and an LED 26 (light source) is disposed so as to face the incident surface 25a on the rear end surface. A reflection sheet (not shown) is disposed on the lower surface of the light guide plate 25.

  Light emitted from the LED 26 enters the light guide plate 25 from the incident surface 25a and is guided, and light incident on the upper and lower surfaces at an incident angle smaller than the critical angle is emitted. At this time, the light emitted from the lower surface of the light guide plate 25 is reflected upward by the reflection sheet. Thereby, light is emitted from the upper surface (emission surface) of the light guide plate 25 toward the air outlet 2b.

  A through hole 25d through which the shaft portion 17 passes is opened at the center of the light guide plate 25, and a communication port 25b is opened at a front portion opposite to the incident surface 25a with respect to the through hole 25d. Since the 1st blowing duct 21 is distribute | arranged to the front part of the housing | casing 2, the communication port 25b which faced the 1st blowing duct 21 is provided in the front part eccentric with respect to the blower outlet 2b.

  A second blowing duct 22 is provided above the light guide plate 25. The 2nd blowing duct 22 has the blower outlet 2b on the upper surface, and is formed in the cylinder shape concentric with the blower outlet 2b. The vertical cross section of the inner wall 22a of the second blow-out duct 22 is formed in a curved shape with a narrow bottom.

  FIG. 12 shows a top view of the housing 2 without the wind direction plate 10. The communication port 25b of the light guide plate 25 is provided with a wind direction variable portion 25c that guides the airflow rising through the first blowout duct 21 forward and is provided in a lattice shape. The front part of the second blow-out duct 22 is provided with a recess 22b that is recessed in the inner wall 22a. The inner surface of the recess 22b is formed of a conical surface having a straight vertical section, and the lower end of the recess 22b is formed along the communication port 25b and the upper end is formed inside the periphery of the outlet 2b.

  In the air blower 1 having the above configuration, when the wind direction plate 10 is popped up and the air outlet 2b is opened, the air blowing fan 30, the ion generating element 40, and the LED 26 are driven. Airflow dust flowing into the housing 2 from the suction port 2a is collected by the filter 23, flows through the suction duct 23 as shown by an arrow A1, and is guided to the blower fan 30 from the suction port 30b. Further, a part of the airflow flows outside the duct member 32 as indicated by an arrow A2, and is guided to the blower fan 30 from the intake port 30c.

  The airflow sent from the exhaust port 30d of the blower fan 30 ascends the first blowout duct 21 as shown by an arrow B1 (see FIG. 5). At this time, ions generated by the ion generating element 40 are included in the airflow. The airflow containing ions flows into the second blowout duct 22 through the communication port 25b and rises as shown by an arrow B2 (see FIG. 5), and radially from the outflow portion 8 as shown by an arrow B3 (see FIG. 5). Is sent out.

  At this time, the airflow flows into the second blowout duct 22 from the communication port 25b disposed in the front portion of the housing 2, and the airflow is guided forward by the wind direction variable portion 25c. Moreover, the flow path width of the front part between the 2nd blowing duct 22 and the wind direction board 10 is expanded by the recessed part 22b. As a result, more airflow than the surroundings is sent to the front of the blower 1.

  Therefore, many air currents containing ions are sent toward the head of the user facing the front front of the blower 1, and the user can be refreshed and sterilized in the vicinity of the user. Moreover, surrounding sterilization, air circulation, etc. can be performed with the airflow containing the ion sent to the side and the back of the air blower 1.

  Further, the light guided through the light guide plate 25 by driving the LED 26 is emitted toward the air outlet 2 b and is reflected radially by the lower surface 10 a of the wind direction plate 10. Thereby, the indirect illumination around the air blower 1 can be performed. At this time, the light emitted from the front portion of the light guide plate 25 is reduced by the communication port 25b. For this reason, the glare of the user who faced the front front of the air blower 1 can be reduced. Further, since the communication port 25b is disposed on the opposite side of the incident surface 25a with respect to the shaft portion 17, light emitted from the front portion of the light guide plate 25 can be further reduced.

  Here, the electrical connection relationship between the plug 6 and the terminal portion 35 will be further described. As described above, the rubber legs 4 are provided at the four corners of the bottom plate 3. The four rubber legs 4 constitute an installation portion that stably supports the blower device 1 by abutting against an installation surface 50 such as a tabletop when the blower device 1 is used.

  The plug 6 is electrically connected by being inserted into the terminal portion 35. On the other hand, the plug 6 has a predetermined length and may not be electrically connected due to poor contact or the like depending on the degree of insertion into the terminal portion 35. Therefore, in this embodiment, when the rubber legs 4 and the plugs 6 provided at least at the four corners of the bottom plate 3 are in contact with the installation surface 50, the plug 6 and the terminal portion 35 are electrically connected (conducted). .

  The case where the plug 6 is not firmly inserted into the terminal portion 35 will be further described as an example. When the blower 1 is installed on the installation surface 50 in a state where the plug 6 is not firmly inserted into the terminal portion 35 (that is, the state where the plug 6 and the terminal portion 35 are not conductive), all the rubber legs 4 and the installation surface 50 are connected. Does not touch. In other words, one or more rubber legs 4 are in a floating state. In such a state, the plug 6 is inserted into the terminal portion 35 by applying a force to the housing 2 so that all the rubber legs 4 and the installation surface 50 are in contact with each other. As a result, the plug 6 and the terminal portion 35 are electrically connected.

  According to the present embodiment, when the rubber leg 4 and the plug 6 are in contact with the installation surface 50, the plug 6 and the terminal portion 35 are electrically connected. That is, since the plug 6 and the terminal portion 35 are electrically connected when the blower device 1 is stably installed on the installation surface 50, the conductive state between the plug 6 and the terminal portion 35 can be easily grasped. Moreover, even if the plug 6 is not sufficiently inserted into the terminal portion 35, the plug 6 and the terminal portion 35 can be easily conducted without directly touching the plug 6.

  Further, the plug 6 is connected to the terminal portion 35 through an insertion hole 3 a that opens in the bottom plate 3 that can be attached to and detached from the housing 2. Further, since the bottom plate 3 is detachably formed by detaching the plug 6, it is necessary to remove the plug 6 from the terminal portion 35 in order to remove the bottom plate 3 from the housing 2. That is, when the bottom plate 3 is removed, power is not supplied to the blower 1, so when the user removes the bottom plate 3 and performs cleaning and maintenance inside the housing 2, the user touches various electronic components to receive an electric shock. There is nothing.

  Further, since the ion generating element 40 and the holding member 45 can be detached from the bottom surface of the housing 2 when the bottom plate 3 is removed, the ion generating element 40 and the holding member 45 can be easily replaced or cleaned. .

  Further, since the filter 23 can be detached from the bottom surface of the housing 2 when the bottom plate 3 is removed, the filter 23 can be easily replaced or cleaned.

  In this embodiment, the rubber legs 4 are provided at the four corners of the bottom plate 3, but the rubber legs 4 may not be provided. In that case, the plug 6 and the terminal portion 35 may be electrically connected when the installation portion provided on the bottom plate 3 and the plug 6 abut on the installation surface 50. In addition, the installation part provided in the baseplate 3 may be the whole of the surface facing the installation surface 50 or a part thereof. That is, what is necessary is just to contact | abut the installation surface 50 at the time of use of the air blower 1, and to support the air blower 1 stably.

  Moreover, although the insertion hole 3a was provided in the bottom plate 3, and it connected to the terminal part 35 by inserting the plug 6 via the insertion hole 3a, it is not restricted to this. That is, the blower 1 can be used by being hung on the wall surface as described above. Therefore, rubber legs (installation portions) and insertion holes may be formed on the back surface of the housing 2, and the plug 6 may be inserted into a terminal portion (not shown) provided on the back surface through the insertion holes formed on the back surface. . Then, when the rubber leg (installation portion) and the plug 6 are brought into contact with the wall surface, the plug 6 and the terminal portion provided on the back surface may be electrically connected. In this case, the back plate can be attached to and detached from the housing 2. That is, the plate part provided with the insertion hole into which the plug 6 is inserted may be detachable from the housing 2.

  In addition, in this embodiment, it is supposed that the latching hole 2c latched on the hook provided on the wall surface of the room is provided on the back surface. However, the present invention is not limited to this, and any housing that does not impair the function of the blower 1 is provided. It may be provided at any position on the body 2. For example, the bottom plate 3 may be provided with a retaining hole.

  Moreover, although the air flow containing the ion couple | bonded with the water | moisture content in the air is sent out by the ion generating element 40, you may send out another charged particle. For example, charged fine particle water may be sent out as charged particles. Specifically, charged fine particle water containing a radical component can be generated by an electrostatic atomizer. That is, condensed water is generated on the surface of the discharge electrode by cooling the discharge electrode provided in the electrostatic atomizer with a Peltier element. When a negative high voltage is applied to the discharge electrode, charged fine particle water is generated from the dew condensation water.

  The present invention can be used for a tabletop blower.
