JP 2003-153831 A JP 2009-297389 A

  When the ion generator is disposed in a portion upstream of the dust collection chamber in the intake passage, as in the vacuum cleaner according to Patent Literature 1 or the vacuum cleaner according to Patent Literature 2, It is possible to neutralize the dust that flows inside or the member that forms the intake passage. However, even if the dust in the intake passage or the dust in the intake passage is neutralized, the dust is charged again by being rubbed with the intake or intake passage before it flows into the dust collection chamber. . As a result, many of the ions supplied in the intake passage disappear before being introduced into the dust collection chamber.

  Furthermore, when the ions are introduced into the dust collection chamber using the negative pressure near the ion outlet, as in the vacuum cleaner according to Patent Document 1, the flow velocity of the swirling flow in the dust collection chamber is compared. Ions are introduced at high points. As described above, when the flow rate of the swirling flow is relatively large, ions may collide violently with the inner wall of the dust collecting chamber. As a result, the dust and ions that have flowed into the dust collection chamber from the intake passage are not effectively mixed inside the dust collection chamber, so that the dust is not effectively discharged.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vacuum cleaner that can effectively neutralize a dust collection chamber.

The introduction port introduces intake air including ions flowing through the introduction path into the dust collection chamber.

In the vacuum cleaner according to the present invention, the dust collection chamber includes a dust cup having a substantially cylindrical shape and an ion introduction path. The introduction port and the dust cup are connected by an ion introduction path. In addition, an ion inlet is formed in the dust cup. The ion introduction port introduces intake air including ions flowing through the ion introduction path into the dust cup. Further, the ion introduction path is connected to the dust cup so that the intake air containing ions flows into the dust cup from the ion introduction port along the direction of the swirl flow of the intake air.

According to the vacuum cleaner according to the present invention, the intake air including the ions generated in the ion generation unit flows into the dust cup in the direction in which the tangent of the portion where the ion introduction port is disposed in the cross section of the dust cup extends. . That is, the intake air containing ions flows into the dust cup in a direction substantially parallel to the direction of the swirling flow in the portion of the dust cup where the ion inlet is disposed. Therefore, according to this configuration, the intake air including the ions flowing through the ion introduction path flows smoothly into the dust cup.

Thus, according to this structure, it is suppressed that ion collides violently inside the ion introduction path or near the ion introduction port. Therefore, the vacuum cleaner according to the present invention can effectively neutralize the dust collection chamber.

Preferably, the outlet port guides the intake air including ions flowing through the outlet path to the outside of the main body, or introduces the intake air from the outer side of the main body to the outlet path.

When an intake air containing ions flows from the ion generation unit to the outside of the main body, the ions are released from the main body into a space such as a room where the electric vacuum cleaner according to the present invention is used. This effectively purifies the space such as the room. On the other hand, as described above, when the intake air containing ions flows from the ion generation unit to the inside of the dust collection chamber, the vacuum cleaner according to the present invention can effectively neutralize the dust collection chamber. it can. Therefore, the vacuum cleaner according to the present invention can effectively neutralize the dust collection chamber and can effectively purify the room and the like.

  As shown in FIGS. 1 and 3, the vacuum cleaner 1 includes an ion generator 140. The ion generator 140 having the ion generator 141 is attached to the case member 130. As shown in FIG. 5, the ion generation unit 140 includes an ion generator 141 that generates ions and an introduction path 142. The ion generator 141 generates ions. The intake path 142 circulates the intake air generated by the electric blower 110 and the intake air that has passed through the filter 150. The introduction path 142 allows the intake air containing the generated ions to flow to the dust collection chamber 120. The introduction path 142 of the ion generation unit 140 may be formed integrally with the case member 130. At this time, only the ion generator 141 may be attached to the case member 130. In the vacuum cleaner 1, the ion generator 141 generates ions while the electric blower 110 is driven.

  As shown in FIG. 3, a stepping motor 162 is disposed below the ion generator 140. The stepping motor 162 is disposed below the introduction path 142 (see FIG. 5) in the ion generator 140.

The introduction port 121 is disposed in the lower portion 127 of the dust collection chamber 120.

  An air outlet 124 is formed in the dust collection chamber 120. The air outlet 124 allows the intake air separated from the dust inside the dust collection chamber 120 to flow out from the dust collection chamber 120 to the intake passage 200. The intake air flowing out of the dust collecting chamber 120 from the air outlet 124 flows through the intake passage 200 toward the electric blower 110 (see FIG. 5). The dust collection chamber 120 has a ceiling portion 129. The ceiling part 129 constitutes a lid member of the dust collection chamber 120 and constitutes a part of the main body 100. The air outlet 124 is disposed below the ceiling portion 129. The air outlet 124 faces the second opening 134 of the case member 130 (see FIGS. 2 and 3). As described above, the second opening 134 is disposed above the first opening 133. Therefore, the outlet 124 is disposed above the inlet 125.

  As shown in FIG. 3, the inside of the connection portion 132 forms a part of the intake passage 200. The inlet 125 of the dust collection chamber 120 is disposed downstream of the first opening 133 with respect to the flow direction of the intake air flowing through the intake passage 200 and faces the rear end portion 135 (see FIG. 4) of the connection portion 132. ing. A fourth opening 137 (see FIG. 5) is formed in the rear end portion 135 of the connection portion 132.

As shown in FIG. 2, the inlet 125 is formed in the upper part 126 of the dust collection chamber 120. Further, the inflow port 125 is disposed above the introduction port 121.

  As shown in FIG. 5, the intake air flowing from the suction port body 101 (see FIG. 1) to the dust collection chamber 120 through the intake passage 200 is collected in the case member 130 (see FIG. 3) and the dust collection chamber 120. By flowing in the order of the first opening 133, the fourth opening 137 of the rear end portion 135, and the inlet 125 of the dust collection chamber 120, the dust flows into the dust collection chamber 120. As will be described later, in a predetermined case, among the intake air generated by the electric blower 110, the intake air passing through the ion generator 140 is supplied with ions generated by the ion generator 141, as shown in FIG. To the outside of the main body 100 through the outlet 144. In another predetermined case, among the intake air generated by the electric blower 110, the intake air passing through the ion generator 140 is supplied with the ions generated by the ion generator 141, as shown in FIG. It flows into the dust collection chamber 120 through the introduction port 121.

  As shown in FIG. 2, the dust collection chamber 120 includes a dust cup 122 and an ion introduction path 128 having a substantially cylindrical shape. As shown in FIG. 5, the ion introduction path 128 connects the introduction port 121 and the dust cup 122. The dust cup 122 has an opening as an ion inlet 123. The ion introduction port 123 introduces the intake air including the ions flowing through the ion introduction path 128 through the introduction port 121 into the dust cup 122.

  Note that the positions of the ion inlet 123 and the inlet 121 in the dust collection chamber 120 in the vertical direction may be substantially the same, and the ion inlet 123 may be below or above the inlet 121.

  The ion introduction path 128 is connected to the dust cup 122 so that the intake air containing ions flows into the dust cup 122 in the direction in which the tangent of the portion where the ion introduction port 123 is arranged in the cross section of the dust cup 122 extends. . As shown in FIG. 5, the ion introduction path 128 extends in a direction parallel to the direction in which the tangent of the portion where the ion introduction port 123 is arranged in the cross section of the dust cup 122. As a result, the intake air including the ions flowing through the ion introduction path 128 via the introduction port 121 enters the inside of the dust cup 122 in the direction in which the tangent of the portion where the ion introduction port 123 is arranged in the cross section of the dust cup 122 extends. Inflow. The ion introduction path 128 may be formed such that a portion of the ion introduction path 128 on the upstream side of the ion introduction port 123 bends in a curved shape toward the lower side of FIG. 5 (the front of the main body 100). Good. Further, the ion introduction path 128 may extend along the outer periphery of the cross section of the substantially circular dust cup 122 like a circular arc concentric with the cross section of the dust cup 122.

  As shown in FIG. 5, the main body 100 has a lead-out path 143 through which intake air containing ions generated by the ion generator 140 is circulated. In the vacuum cleaner 1, the lead-out path 143 is a part of the ion generator 140. However, the lead-out path 143 may be configured separately from the ion generation unit 140 in the main body 100. In the ion generator 140, a part of the introduction path 142 is used for the lead-out path 143. On the other hand, a part of the outlet path 143 is used for the inlet path 142. The main body 100 is formed with a lead-out port 144 through which intake air including ions flowing through the lead-out path 143 is led out to the outside of the main body 100. The lead-out port 144 may be a part of the main body 100, a part of the case member 130 (see FIG. 3), or a part of the ion generator 140.

  The lead-out port 144 is an opening formed on the outer peripheral surface 100a of the main body 100, the outer peripheral surface of the case member 130 (see FIG. 3), or the outer peripheral surface of the ion generator 140. The outlet port 144 may be formed in a slit shape. The outlet port 144 may be provided with a filter such as a net or a non-woven fabric.

  In the vacuum cleaner 1, the length of the ion introduction path 128 is shorter than the length of the introduction path 142 of the ion generation unit 140. Further, the sum of the length of the ion introduction path 128 and the length of the introduction path 142 of the ion generation unit 140 is smaller than the length from the suction port body 101 to the inlet 125, and the dust cup 122 and the electric blower 110 Less than the distance between.

  As shown in FIG. 9, the vacuum cleaner 1 includes a switching unit 160. In addition, as shown in FIG. 5, the flow path switching valve 161 of the switching unit 160 includes a first direction from the ion generator 141 of the ion generation unit 140 to the dust collection chamber 120 via the introduction path 142, and an ion The direction in which the intake air containing the ions generated in the ion generator 140 flows is switched to one of the second direction toward the outside of the main body 100 from the ion generator 141 of the generator 140 via the lead-out path 143. . The flow path switching valve 161 of the switching unit 160 is disposed in the introduction path 142 of the ion generation unit 140.

  Below, the control which concerns on the vacuum cleaner 1 is demonstrated using FIG. 9 and FIG. As illustrated in FIG. 9, the control unit 170 includes a determination unit 171, a timer 172, a storage unit 173, and a valve switching unit 174. The switching unit 160 includes at least a flow path switching valve 161, a stepping motor 162, and a valve switching unit 174 of the control unit 170. The control unit 170 controls the switching unit 160 based on the operation of the operation unit 4.

  The determination unit 171 determines a condition relating to control of the electric vacuum cleaner 1. The timer 172 measures time. The storage unit 173 stores a strong operation mode in which the output of the electric blower 110 is a predetermined output and a weak operation mode in which the output of the electric blower 110 is smaller than the predetermined output. In addition, the vacuum cleaner 1 may have a normal mode in addition to the strong operation mode and the weak operation mode. The normal mode is a mode in which the output of the electric blower 110 is smaller than that in the strong operation mode and the output of the electric blower 110 is larger than that in the weak operation mode. Furthermore, as will be described later, the storage unit 173 stores a static elimination mode in which the first direction and the second direction are switched based on a predetermined time in a mode excluding the weak operation mode (for example, the strong operation mode). ing. As described above, the first direction is a direction from the ion generator 141 of the ion generator 140 toward the dust collection chamber 120 via the introduction path 142 (see FIG. 7). The second direction is a direction from the ion generator 141 of the ion generator 140 toward the outside of the main body 100 via the lead-out path 143 (see FIG. 5).

  The controller 170 is connected to the ion generator 141, the operation unit 4, and the electric blower 110 of the ion generator 140. The control unit 170 controls the ion generator 141 and the electric blower 110 based on the operation of the operation unit 4. Further, the valve switching unit 174 of the control unit 170 is connected to the stepping motor 162. The valve switching unit 174 is a part of the control unit 170 and a part of the switching unit 160. The valve switching unit 174 controls the operation of the stepping motor 162.

  The stepping motor 162 is mechanically or electronically connected to the flow path switching valve 161 disposed in the introduction path 142 (see FIG. 5). Based on the operation of the stepping motor 162, the flow path switching valve 161 opens the intake side of the introduction path 142 (closes the exhaust side), and the flow path switching valve 161 closes the intake side (opens the exhaust side). ) Can be switched. As shown in FIG. 8, when the flow path switching valve 161 opens the intake side (closes the exhaust side), the direction from the ion generator 141 toward the dust collection chamber 120 via the introduction path 142 (that is, Inhalation containing ions flows in the first direction). On the other hand, as shown in FIG. 6, when the flow path switching valve 161 closes the intake side of the introduction path 142 (opens the exhaust side), the outside of the main body 100 is removed from the ion generation unit 140 via the lead-out path 143. Inhalation containing ions flows in a direction toward the direction (that is, the second direction).

  As shown in FIG. 10, the operation unit 4 includes a button 41 for selecting the strong driving mode as the first mode and a button 42 for selecting the weak driving mode as the second mode. In the operation unit 4, the button 41 and the button 42 constitute a first selection unit. The operation unit 4 also has a stop button 44 that stops the driving of the electric blower 110. Furthermore, the operation unit 4 includes a button 43 as a second selection unit that selects a charge removal mode.

  However, the number of buttons as the first selection unit may be one. With this one button, the mode may be changed from the strong operation mode to the weak operation mode, or the mode may be changed in the order of the normal mode, the strong operation mode, the weak operation mode, or the like. The number of buttons as the first selection unit and the second selection unit may be one. With this one button, for example, the mode may be changed in the order of the strong operation mode, the static elimination mode, and the weak operation mode. Further, the operation unit 4 may not have the stop button 44. In this case, in the operation unit 4, for example, the strong operation mode, the static elimination mode, the weak operation mode, and the stop of the driving of the vacuum cleaner 1 are performed in order of one button as the first selection unit and the second selection unit. The mode or the like may be changed.

As described later, a discharge mode, in the mode except the weak operation mode (e.g. strong operation mode), the flow path switching valve 161 on the basis of a direction to a predetermined time T _1, which intake air containing ions flows (see FIG. 9 ) Is the mode to switch. That is, when the storage unit 173 of the control unit 170 stores the strong operation mode and the weak operation mode, the static elimination mode constitutes a part of the strong operation mode. Therefore, when the storage unit 173 of the control unit 170 stores the strong operation mode and the weak operation mode, the electric fan 110 is driven as the strong operation mode by operating the button 43, and the strong operation mode is The switching unit 160 operates as a charge removal mode in the operation mode.

  Hereinafter, the flow of intake air generated by the electric blower 110 will be described. 5 and 7 indicate the directions of intake air flow before and after passing through the electric blower 110, respectively.

  When driving of the vacuum cleaner 1 is started by the user operating the operation unit 4 (see FIG. 1), at least the ion generator 140 (see FIG. 5) and the electric blower 110 are driven. When the ion generator 140 is driven, the ion generator 141 generates ions.

  When driving of the electric blower 110 is started, intake air is generated. The intake air is sucked into the suction port body 101 (see FIG. 1) from the suction port. The intake air sucked into the suction port body 101 passes through the extension pipe 102, the connection pipe 103, the suction hose 104, and the connection pipe 105 in this order, and is sucked into the main body 100 of the electric vacuum cleaner 1. Inside the main body 100, the intake air flows from the inside of the connecting pipe 105 and the inside of the connecting portion 132 (see FIG. 5) through the inlet 125 into the dust collecting chamber 120.

  The intake air flowing into the dust cup 122 from the inflow port 125 swirls inside the dust cup 122 as indicated by white arrows in FIG. The intake air is separated from dust by swirling inside the dust cup 122. The intake air separated from the dust inside the dust cup 122 flows through the intake passage 200 toward the electric blower 110 via the air outlet 124 (see FIG. 2). At this time, the intake air separated from the dust flows from the front of the main body 100 toward the rear in front of the paper surface of FIG. As shown in FIG. 5, a filter 150 is installed on the downstream side of the electric blower 110. The intake air passes through the filter 150, is purified, passes through the exhaust path 107, and is discharged from the exhaust port 108 to the outside of the main body 100. Part of the intake air that has passed through the filter 150 flows into the introduction path 142 of the ion generation unit 140 through the return reflux path 109.

  As indicated by a black arrow in FIG. 5, when the electric blower 110 is driven and the flow path switching valve 161 closes the intake side, a part of the intake air generated by the electric blower 110 is returned. After flowing into the introduction path 142 via the flow path 109, it passes through the ion generator 141 and the lead-out path 143, and is discharged outside the main body 100 via the lead-out port 144. On the other hand, as shown by the white arrow in FIG. 7, when the electric blower 110 is driven and the flow path switching valve 161 opens the intake side, a part of the intake air generated by the electric blower 110 is After flowing into the lead-out path 143 through the lead-out port 144, the ion generator 141 is passed. The intake air supplied with ions by passing through the ion generator 141 flows into the ion introduction path 128 through the third opening 136 and the introduction port 121, and then flows into the dust cup 122 through the ion introduction port 123. Flows into the interior.

  As shown in FIG. 7, the ions supplied from the ion generator 140 to the intake air swirl inside the dust cup 122 together with the intake air. At this time, ions in the intake air collide with dust in the intake air. In addition, ions in the intake air collide with the inner wall surface 220 of the dust cup 122.

  The dust in the intake air is often charged due to friction with the intake air or contact between the dust. Also, the inner wall surface 220 of the dust cup 122 is often charged by friction with intake air or contact with dust. The dust supplied from the ion generator 140 collides with the charged dust or the inner wall surface 220 of the dust cup 122 as described above, whereby the dust or the dust cup 122 is neutralized.

  In the dust collection chamber 120, the inlet 121 is disposed below the outlet 124. Therefore, the ions supplied from the ion generation unit 140 can swirl inside the dust collection chamber 120 on the intake air from the introduction port 121 without being discharged from the air outlet 124 shown in FIG. .

  When the user operates the operation unit 4, the driving of the electric blower 110 is stopped. After the driving of the electric blower 110 is completely stopped, the user removes the dust cup 122 from the main body 100 and discards the dust accumulated in the dust cup 122.

  In the vacuum cleaner 1, when the driving of the electric blower 110 is completely stopped, the dust and the dust cup 122 are neutralized by ions supplied from the ion generator 140. Therefore, when the dust is discarded from the dust cup 122, it is prevented that the dust is scattered due to static electricity or remains attached to the dust cup 122. The dust cup 122 from which the dust has been removed is mounted on the main body 100 of the vacuum cleaner 1 again.

  Below, in the vacuum cleaner 1, the control at the time of neutralizing dust and the dust cup 122 with the ion which the ion generation part 140 supplies is demonstrated.

  When the electric blower 110 is driven and the vacuum cleaner 1 is cleaning a room or the like, the flow path switching valve 161 closes the intake side of the introduction path 142 (see FIG. 6). That is, the switching unit 160 (see FIG. 9), for example, changes the direction in which the intake air including ions flows after the electric blower 110 starts to be driven by the user pressing the button 41, the button 42, or the button 43. Switching to the second direction. As a result, as shown in FIG. 5, ions generated by the ion generator 141 are supplied to the intake air through the introduction path 142. The intake air supplied with ions is discharged to the outside of the main body 100 via the outlet port 144.

  On the other hand, when the user presses the stop button 44 of the operation unit 4 to stop the driving of the electric blower 110 and the vacuum cleaner 1 finishes cleaning, the flow path switching valve 161 is connected to the exhaust side of the introduction path 142. Is closed (see FIG. 8). That is, the switching unit 160 (see FIG. 9) switches the direction in which the intake air containing ions flows to the first direction after the operation unit 4 is operated so as to stop the driving of the electric blower 110. As a result, as shown in FIG. 7, ions generated by the ion generator 141 are supplied to the intake air through the introduction path 142. The intake air supplied with ions flows into the ion introduction path 128 through the third opening 136 and the introduction port 121, and then flows into the dust cup 122 through the ion introduction port 123.

  Thus, when the vacuum cleaner 1 is being cleaned, the vacuum cleaner 1 can supply ions to a space such as a room where the vacuum cleaner 1 is used, and at the end of cleaning, the dust collection chamber 120. Can be supplied with ions.

  However, the vacuum cleaner 1 can supply ions to the inside of the dust collection chamber 120 even when cleaning is being performed, depending on the mode selected by the user. Hereinafter, control when the vacuum cleaner 1 supplies ions to the inside of the dust collecting chamber 120 even when cleaning is performed according to the mode selected by the user will be described with reference to FIG. 11. In the vacuum cleaner 1, the determination unit 171 determines the conditions illustrated in FIG. 11 based on the operation of the operation unit 4.

  In step S10a, the user operates the operation unit 4 (see FIG. 9). Thereby, electric blower 110 (refer to Drawing 9) starts a drive in Step S10b, and cleaning by electric vacuum cleaner 1 is started.

  In step S11, it is determined whether or not the weak operation mode is selected after the driving of the electric blower 110 is started. If it is determined in step S11 that the weak operation mode is selected, the process proceeds to step S19. On the other hand, if it is determined in step S11 that the weak operation mode is not selected, and, for example, either the strong operation mode or the normal mode is selected, the process proceeds to step S12.

  In step S12, it is determined whether the static elimination mode is selected. If it is determined in step S12 that the static elimination mode is selected, the process proceeds to step S18. On the other hand, if it is determined in step S12 that the static elimination mode is not selected, the process proceeds to step S13.

At step S18, whether a predetermined time T ₁ is passed at the output is greater mode of the electric blower 110 (see FIG. 9) is determined than the weak operation mode. As described above, the vacuum cleaner 1 has the weak operation mode, the strong operation mode, and the static elimination mode. In the electric vacuum cleaner 1, a discharge mode, in strong operation mode is a mode for switching the flow path switching valve 161 on the basis of the direction of air containing ions to flow at a given time T ₁ (see FIG. 9). In step S18, if it is determined that the predetermined time T ₁ is has elapsed, the process proceeds to step S19. In step S18, if the predetermined time T ₁ is not elapsed is determined, the process proceeds to step S13.

In step S13, the flow path switching valve 161 opens the exhaust side (closes the intake side) of the introduction path 142 (see FIG. 6). As a result, the intake air including the ions generated by the ion generator 141 is discharged from the outlet port 144 to the outside of the main body 100 through the outlet path 143. Thus, the electric vacuum cleaner 1, when it is being cleaned, when the weak operation mode or static elimination mode is not selected, or when a predetermined time T ₁ is not passed in the neutralization mode, the vacuum cleaner Ions are supplied to a space such as a room where 1 is used. Thereby, a space such as a room is purified.

In step S19, the flow path switching valve 161 opens the intake side (closes the exhaust side) of the introduction path 142 (see FIG. 8). Thereby, the intake air containing the ions generated by the ion generator 141 flows into the dust collection chamber 120 through the third opening 136 and the introduction port 121. That is, in the vacuum cleaner 1, even when cleaning is being performed, ions are supplied to the dust collection chamber 120 when the weak operation mode is selected or when the predetermined time T ₁ has elapsed in the static elimination mode. The As a result, the electric vacuum cleaner 1, even if it is being cleaned, when the weak operation mode has passed a predetermined time T ₁ is the time application or removal mode is selected, for discharge inside the dust collecting chamber 120 Can do.

After step S19, the process returns to step S11. At this time, when experiencing step S19 from experiencing step S18 is that the predetermined time T ₁ through the steps S11 and S12 during different other predetermined time, channel switching in step S13 The valve 161 closes the intake side. That is, when experiencing step S19 from experiencing step S18, the other predetermined time only the flow path switching valve 161 which is different from the predetermined time T ₁ is open the intake side. Thus, in the static elimination mode, the flow path switching valve 161 switches between the intake side and the exhaust side of the introduction path 142 based on at least the predetermined time T ₁ . Thereby, in the static elimination mode, the intake air supplied with ions intermittently flows into the dust collection chamber 120.

  On the other hand, when the vacuum cleaner 1 is cleaning in the weak operation mode, the flow path switching valve 161 always opens the intake side (closes the exhaust side) of the introduction path 142 (see FIG. 8) ( (See Step S11 and Step S19). That is, when the vacuum cleaner 1 is cleaning in the weak operation mode, ions are always supplied into the dust collection chamber 120. Thereby, when the vacuum cleaner 1 is cleaning in the weak operation mode, the dust collecting chamber 120 can always be neutralized.

  In step S <b> 14, it is determined whether or not the vacuum cleaner 1 finishes cleaning, that is, whether or not the operation unit 4 has been operated so as to stop driving the electric blower 110 (see FIG. 9). If it is determined in step S14 that the electric vacuum cleaner 1 does not end the cleaning, the process returns to step S11. As described above, when the user operates the stop button 44 (see FIG. 10) of the operation unit 4, the cleaning by the electric vacuum cleaner 1 can be terminated.

  If it is determined in step S14 after step S13 that the operation unit 4 has been operated, the process proceeds to step S15. In step S15, the flow path switching valve 161 opens the intake side of the introduction path 142 (closes the exhaust side). Thereby, the intake air containing the ions generated by the ion generator 141 flows into the dust collection chamber 120 through the third opening 136 and the introduction port 121.

In step S16 following step S15, it is determined whether or not a predetermined time T ₂ has elapsed. When the predetermined time T ₂ is determined that has elapsed in step S16, the driving of the electric blower 110 is stopped in step S17. Thereby, the cleaning by the electric vacuum cleaner 1 is completed. That is, when the cleaning by the electric vacuum cleaner 1 is terminated, the intake air containing ions is supplied to the dust collection chamber 120 for a predetermined time T _2. However, in this case, intake air containing ions may be supplied to the dust collection chamber 120 by a predetermined amount. Further, the predetermined time T ₁ used for the determination in step S18 and the predetermined time T ₂ used for the determination in step S16 may be the same time or may be different from each other.

  As described above, the vacuum cleaner 1 includes the suction port body 101, the electric blower 110, the intake passage 200, the dust collection chamber 120, and the ion generation unit 140. The suction port body 101 has a suction port. The electric blower 110 generates intake air. The intake passage 200 guides intake air from the suction port body 101 to the electric blower 110. The dust collection chamber 120 is disposed in the intake passage 200 and separates dust by turning the intake air. The ion generator 140 includes an ion generator 141 that generates ions and an introduction path 142. The introduction path 142 circulates the intake air containing the generated ions to the dust collection chamber 120. The dust collection chamber 120 has an inlet 125 and an inlet 121. The inlet 125 allows the intake air flowing through the intake passage 200 to flow into the dust collection chamber 120. The introduction port 121 introduces the intake air that is disposed below the inflow port 125 and includes ions flowing through the introduction path 142 into the dust collection chamber 120.

  In the vacuum cleaner 1, the introduction path 142 is configured as a part of the ion generation unit 140. When the intake air containing ions flows into the dust collecting chamber 120 and flows through the introduction path 142, the introduction path 142 flows through the intake path 200. The portion between the inlet 125 and the suction port body 101 is not circulated. Therefore, most of the ions generated by the ion generator 141 are introduced into the dust collection chamber 120 without disappearing before being introduced into the dust collection chamber 120.

  Further, in the vacuum cleaner 1, the intake air flowing through the intake passage 200 from the suction port body 101 to the dust collecting chamber 120 flows into the dust collecting chamber 120 from the inlet 125. Furthermore, the inlet 121 for introducing the intake air containing ions into the dust collection chamber 120 is disposed below the inlet 125. That is, the introduction port 121 is disposed at a place where the flow rate of the swirling flow is relatively small in the dust collection chamber 120. Thus, in the vacuum cleaner 1, the dust flowing into the dust collection chamber 120 from the intake passage 200 and the ions introduced into the dust collection chamber 120 from the introduction path 142 are generated inside the dust collection chamber 120. It is configured to mix effectively. Therefore, the vacuum cleaner 1 can effectively neutralize the dust collection chamber 120.

  The dust collection chamber 120 includes a dust cup 122 having a substantially cylindrical shape and an ion introduction path 128. The inlet 121 and the dust cup 122 are connected by an ion introduction path 128. The dust cup 122 is formed with an ion introduction port 123. The ion introduction port 123 introduces the intake air including the ions flowing through the ion introduction path 128 into the dust cup 122. Further, the ion introduction path 128 is connected to the dust cup 122 so that the intake air containing ions flows into the dust cup 122 in the direction in which the tangent of the portion where the ion introduction port 123 is arranged in the cross section of the dust cup 122 extends. ing.

  According to this configuration, the intake air including the ions generated by the ion generation unit 140 flows into the dust cup 122 in the direction in which the tangent of the portion where the ion introduction port 123 is arranged in the cross section of the dust cup 122 extends. That is, the intake air containing ions flows into the dust cup 122 in a direction substantially parallel to the direction of the swirling flow in the portion of the dust cup 122 where the ion inlet 123 is disposed. Therefore, according to this configuration, the intake air including the ions flowing through the ion introduction path 128 flows smoothly into the dust cup 122. In this way, it is suppressed that the ions collide violently inside the ion introduction path 128 or near the ion introduction port 123 or the like. Therefore, the vacuum cleaner 1 can further effectively neutralize the dust collection chamber 120.

  In the vacuum cleaner 1, the inlet 125 is formed in the upper part 126 of the dust collection chamber 120. Further, the dust collecting chamber 120 is formed with an air outlet 124. The air outlet 124 is disposed above the inflow port 125. Further, the air outlet 124 causes the intake air that has flowed into the dust collection chamber 120 from the inlet 125 to flow out from the dust collection chamber 120 to the intake passage 200.

  According to this configuration, the air outlet 124 is disposed closer to the inlet 125 than the inlet 121 in the vertical direction of the dust collection chamber 120. With respect to the flow direction of the intake air flowing from the intake passage 200 to the dust collecting chamber 120, the flow rate of the swirling flow is particularly large at a position immediately downstream of the inlet 125. On the other hand, the inlet 121 and the outlet 124 are arranged at positions relatively far from each other in the vertical direction of the dust collection chamber 120. As described above, the inlet 121 is disposed in the dust collection chamber 120 where the flow rate of the swirling flow is relatively small, and is disposed at a position farther from the outlet 124 than the inlet 125. Therefore, according to this configuration, the intake air flowing into the dust collection chamber 120 from the inflow port 125 can sufficiently swirl inside the dust collection chamber 120, and the intake air containing ions enters the dust collection chamber 120. It can be effectively mixed with the dust flowing in. Therefore, the vacuum cleaner 1 can further effectively neutralize the dust collection chamber 120.

  The vacuum cleaner 1 includes a main body 100. The main body 100 accommodates at least the dust collection chamber 120 and the ion generation unit 140. The main body 100 has a lead-out path 143. The lead-out path 143 distributes the intake air including the ions generated by the ion generator 141 of the ion generator 140. Further, the main body 100 is formed with a lead-out port 144 that leads out the intake air including ions flowing through the lead-out path 143 to the outside of the main body 100. Moreover, the vacuum cleaner 1 includes a switching unit 160. The switching unit 160 switches the direction in which the intake air containing the ions generated by the ion generator 141 flows in one of the first direction and the second direction. The first direction is a direction in which intake air containing ions travels from the introduction path 142 to the dust collection chamber 120 via the introduction port 121. The second direction is a direction in which the intake air including ions is directed outward from the main body 100 through the outlet path 143 through the outlet port 144.

  According to this configuration, when the switching unit 160 switches the direction in which the intake air containing ions flows, the intake air containing the ions is either from the ion generation unit 140 inside the dust collection chamber 120 or outside the main body 100. To flow. When intake air containing ions flows from the ion generation unit 140 to the outside of the main body 100, the ions are released from the main body 100 into a space such as a room where the vacuum cleaner 1 is used. This effectively purifies the space such as the room. On the other hand, when the intake air containing ions flows from the ion generator 140 into the dust collection chamber 120, the vacuum cleaner 1 can effectively neutralize the dust collection chamber 120. Therefore, the vacuum cleaner 1 can effectively neutralize the dust collection chamber 120 and can effectively purify the room and the like.

  As described above, according to the vacuum cleaner 1, the dust collection chamber 120 can be effectively neutralized.

  The vacuum cleaner 1 includes a suction port body 101, an electric blower 110, an intake passage 200, a dust collection chamber 120, an ion generator 140 having an ion generator 141, and a main body 100. The suction port body 101 has a suction port. The electric blower 110 generates intake air. The intake passage 200 guides intake air from the suction port body 101 to the electric blower 110. The dust collection chamber 120 is disposed upstream of the electric blower 110 in the intake passage 200, and rotates the intake air to separate the dust. The ion generator 141 of the ion generator 140 generates ions. The ion generator 140 has an introduction path 142. In the introduction path 142, the ions generated by the ion generator 141 are supplied to the intake air generated by the electric blower 110. The intake air containing ions flows from the introduction path 142 toward the dust collection chamber 120. The main body 100 accommodates at least the dust collection chamber 120 and the ion generation unit 140 and has a lead-out path 143. In the lead-out path 143, the ions generated by the ion generator 141 are supplied to the intake air generated by the electric blower 110, whereby the intake air containing the ions flows.

  In the vacuum cleaner 1, the inlet 121 is formed in the dust collecting chamber 120, and the outlet 144 is formed in the main body 100. The introduction port 121 introduces the intake air including ions flowing through the introduction path 142 into the dust collection chamber 120. The outlet port 144 guides the intake air including the ions flowing through the outlet path 143 to the outside of the main body 100.

  Furthermore, the vacuum cleaner 1 includes a switching unit 160, an operation unit 4, and a control unit 170. The control unit 170 includes a determination unit 171, a timer 172, a storage unit 173, and a valve switching unit 174. The switching unit 160 includes a first direction from the introduction path 142 toward the dust collection chamber 120 via the introduction port 121, and a second direction from the lead-out path 143 toward the outside of the main body 100 via the lead-out port 144. The direction in which the intake air containing the ions generated by the ion generator 141 flows is switched to any one of the above. The switching unit 160 includes a flow path switching valve 161, a valve switching unit 174, and a stepping motor 162. The operation unit 4 switches between starting and stopping driving of the electric blower 110. The control unit 170 is connected to the operation unit 4 and the stepping motor 162 of the switching unit 160, and the valve switching unit 174 of the switching unit 160 controls the stepping motor 162 based on the operation of the operation unit 4. After the operation unit 4 is operated so as to start driving the electric blower 110, the valve switching unit 174 switches the direction in which the intake air containing ions flows to the second direction, and the operation unit 4 operates the electric blower 110. After the operation is stopped, the direction in which the intake air including the ions flows is switched to the first direction.

  According to the vacuum cleaner 1, after the operation unit 4 is operated so as to start driving the electric blower 110, intake air containing ions flows from the outlet path 143 to the outside of the main body 100 through the outlet port 144. As described above, the flow path switching valve 161 of the switching unit 160 closes the intake side of the introduction path 142 (opens the exhaust side). Thereby, when the vacuum cleaner 1 is cleaning, air containing ions is discharged to the outside of the main body 100. Therefore, in the vacuum cleaner 1, when the vacuum cleaner 1 is cleaning, air, such as a room | chamber interior, can be purified. On the other hand, after the operation unit 4 is operated so as to stop the driving of the electric blower 110, the switching is performed so that the intake air containing ions flows from the introduction path 142 to the inside of the dust collecting chamber 120 through the introduction port 121. The flow path switching valve 161 of the section 160 opens the intake side of the introduction path 142 (closes the exhaust side). Thereby, when the vacuum cleaner 1 finishes cleaning, air containing ions is introduced into the dust collection chamber 120.

  Thus, the vacuum cleaner 1 can send out the ions supplied to the intake air to different places during cleaning and at the end of cleaning. Therefore, the vacuum cleaner 1 can effectively supply ions to the intake air.

  In the vacuum cleaner 1, the control unit 170 is connected to the electric blower 110 and controls the electric blower 110. The control unit 170 stores at least a strong operation mode and a weak operation mode. The strong operation mode is a mode in which the output of the electric blower 110 is a predetermined output. On the other hand, the weak operation mode is a mode in which the output of the electric blower 110 is an output smaller than a predetermined output. The operation unit 4 also includes a button 41 for selecting the strong driving mode and a button 42 for selecting the weak driving mode. Further, the flow path switching valve 161 of the switching unit 160 is operated by operating the button 41, the button 42, or the button 43 of the operation unit 4 so as to start driving the electric blower 110, and by operating the button 42. When the weak operation mode is selected, the intake side of the introduction path 142 is opened (the exhaust side is closed).

  Thereby, when the electric blower 110 is driven in the weak operation mode, air containing ions is introduced into the dust collection chamber 120. In this way, the vacuum cleaner 1 sends out the ions supplied to the intake air to different places in the strong operation mode and the weak operation mode even during cleaning and at the end of cleaning. be able to. Therefore, the vacuum cleaner 1 can effectively supply ions to the intake air during cleaning, at the end of cleaning, or according to the mode of cleaning.

The controller 170 has a timer 172 that measures time. Further, the storage unit 173 of the control unit 170 stores a static elimination mode. In the static elimination mode, the first direction and the second direction are at least at a predetermined time T ₁ in a mode in which the output of the electric blower 110 is larger than the output of the electric blower 110 in the weak operation mode (for example, the strong operation mode). It is a mode that can be switched based on. Further, the operation unit 4 has a button 43 for selecting a charge removal mode. Furthermore, the flow path switching valve 161 starts driving the electric blower 110 when the button 41, the button 42, or the button 43 of the operation unit 4 is operated, and the button 42 or the button 43 of the operation unit 4 is operated. strong operation mode is selected by, and when the charge removing mode by the button 43 is operated is selected, when the time timer 172 measures has passed a predetermined time T _1, the introduction path 142 Open the intake side (close the exhaust side).

Thereby, even when the vacuum cleaner 1 is cleaning, the vacuum cleaner 1 sends out the intake air containing ions into the dust collecting chamber 120 when the predetermined time T ₁ has passed in the static elimination mode. Can do. As described above, the vacuum cleaner 1 is in a predetermined state even during cleaning in the strong operation mode and the weak operation mode during cleaning and at the end of cleaning, and even in the strong operation mode. Before and after the elapse of time T ₁ , ions supplied to the intake air can be sent to different places. Therefore, the vacuum cleaner 1 can supply ions to the intake air more effectively during cleaning, at the end of cleaning, or in accordance with a cleaning mode or the like.

  As described above, the vacuum cleaner 1 can effectively supply ions to the intake air.
