The discharge part case 23, the filter part case 24, the inflow part case 25, and the dust collecting part case 26 are disassembled into the state shown in FIG. 8 or shown in FIG. 7 by a predetermined operation (for example, an operation with respect to the lock mechanism). It is configured so that it can be assembled into a state. Moreover, only the dust collection part case 26 can also be removed from the state shown in FIG.

Hereinafter, the dust collection unit 13 configured by combining the discharge portion case 23, the filter portion case 24, the inflow portion case 25, and the dust collection portion case 26 will be described. Moreover, in the description regarding the dust collection unit 13 below, the upper and lower sides are specified based on the direction shown in FIG.
As shown in FIGS. 7 to 9, an inflow port 25 a is formed on the front side of the inflow portion case 25. Further, an outlet 23 a is formed on the rear side of the discharge unit case 23. The outflow port 23a is disposed at a position above the inflow port 25a.

  As shown in FIGS. 8-10, the inflow part case 25 is a site | part which introduce | transduces dust-containing air into the inside from the inflow port 25a, and is equipped with the turning chamber 25b inside. The upper part of the swirl chamber 25b consists of a cylindrical part 25c. The lower part of the swirl chamber 25b is composed of a conical part 25d.

The cylindrical portion 25c has a hollow cylindrical shape. The cylindrical portion 25c is arranged such that the cross-sectional center axis L is directed in the vertical direction. The conical portion 25d has a hollow conical shape with a tip portion cut off. The conical portion 25d is arranged in the vertical direction so that the cross-sectional central axis L coincides with the central axis of the cylindrical portion 25c.
The conical portion 25d is provided so as to extend downward from the lower end portion of the cylindrical portion 25c so that the upper end portion is connected to the lower end portion of the cylindrical portion 25c and the diameter decreases toward the lower side.

A continuous space composed of the internal space of the cylindrical portion 25c and the internal space of the conical portion 25d thus formed constitutes the swirl chamber 25b. The swirl chamber 25b is a space for swirling the dust-containing air introduced from the inflow port 25a.
As shown in FIG. 9, an inflow port 25a opens at the upper part of the cylindrical part 25c (upper side wall forming the swirl chamber 25b). The dust-containing air flowing in from the inflow port 25a flows in along the side surface of the cylindrical swirl chamber 25b.

Next, as shown in FIGS. 8 to 10, a zero-order opening 25e is formed on the side wall of the cylindrical portion 25c of the swirl chamber 25b. The zero-order opening 25e is disposed below the inflow port 25a in the direction of the cross-sectional central axis L of the swirl chamber 25b.
More specifically, the zero-order opening 25e is disposed below the inflow port 25a in the direction of the central axis L of the swirl chamber 25b, that is, downstream of the swirl flow generated in the swirl chamber 25b.

Next, the lower end portion of the conical portion 25d that forms the swirl chamber 25b opens downward (in the direction of the central axis L of the cross section ). This opening formed at the lower end of the conical portion 25d is the primary opening 25f. Accordingly, the primary opening 25f is disposed downstream of the zero-order opening 25e in the swirling flow generated in the swirling chamber 25b.
A partition wall 30 is provided outside the conical portion 25d. The partition wall 30 has a substantially cylindrical shape having substantially the same diameter as the cylindrical portion 25c. The upper end of the partition wall 30 is connected to the vicinity of the connecting portion between the cylindrical portion 25c and the conical portion 25d.

Next, the dust collector case 26 has a cup shape in which the lower part is closed and the upper part is opened. The dust collecting unit case 26 is disposed outside and below the inflow unit case 25. That is, the cylindrical portion 25 c and the conical portion 25 d that form the swirl chamber 25 b are located inside the dust collecting portion case 26.
In this state, the lower side of the upper end of the zero-order opening 25e of the cylindrical portion 25c of the inflow portion case 25 and the entire conical portion 25d and the partition wall 30 are accommodated in the dust collecting portion case 26. Further, the lower end of the partition wall 30 is in close contact with the sealing material provided on the bottom surface of the dust collecting unit case 26.
The opening 26 a of the dust collecting part case 26 is sealed by a lid part 25 g that protrudes in a flange shape from the outer peripheral surface of the inflow part case 25.

The space formed between the inflow portion case 25 and the dust collecting portion case 26 is divided into two by the partition wall 30. Of the two spaces thus formed, the space formed outside the cylindrical portion 25c and the partition wall 30 is the zero-order dust collection chamber 31, and is formed below and outside the conical portion 25d and inside the partition wall 30. The space is the primary dust collection chamber 32.
That is, the space formed between the outer surface of the dust collecting unit case 26 and the inflow unit case 25 is the dust collecting chambers 31 and 32 that hold the dust discharged from the swirl chamber 25b.

  The zero-order dust collection chamber 31 communicates with the zero-order opening 25e and surrounds the entire outer periphery of the swirl chamber 25b. The zero-order dust collection chamber 31 extends downward from the zero-order opening 25e. The primary dust collecting chamber 32 extends from below the primary opening 25f to the entire outer periphery of the conical portion 25d.

  Next, the filter part case 24 is provided so as to cover the upper opening of the cylindrical part 25c. The filter case 24 is formed with a mesh-shaped discharge port 24a. The discharge port 24a is configured by a fine hole formed by opening a side wall and a part of the lower part of a tube having a substantially cylindrical shape in the upper part and a substantially conical shape in the lower part.

Therefore, the swirl force of the airflow above the swirl chamber 25b is increased and the separation performance can be further improved. And this discharge port 24a and the outflow port 23a are connected by the discharge pipe 23b formed in the discharge part case 23. FIG.
The discharge pipe 23 b is mainly formed by the discharge part case 23. The discharge port 24 a is formed in the filter part case 24, and the upper end wall of the swirl chamber 25 b is formed by a part of the bottom surface of the filter part case 24.

  When the dust collection unit 13 having the above-described configuration is appropriately attached to the housing portion 15a, the inlet 25a is connected to the intake air passage 19 to communicate with the intake hose connection port 9, and the outlet 23a is connected. Connected to the port 22 and communicated with the exhaust air passage 21.

Next, the function of the dust collection unit 13 will be described with reference to FIG. Note that the flow of the airflow from the intake air passage 19 to the exhaust port 50 of the main body 6 described later is indicated by a solid arrow as a path W in the drawing. The exhaust port 50 is an opening that exhausts the airflow from which dust is separated from the main body 6.
Referring to FIG. 10, when the suction operation of the electric blower 10 is started, the dust-containing air sucked from the suction port body 2 passes through the intake air passage 19 as described above, and is collected from the inlet 25a. 13 flows into the interior.

The dust- containing air that has flowed into the dust collection unit 13 flows along the inner peripheral surface of the cylindrical portion 25c that constitutes the swirl chamber 25b.
The taken-in dust-containing air forms a swirling airflow that rotates in a predetermined direction along the side wall in the swirling chamber 25b. This whirling airflow flows downward due to the path structure.

  A centrifugal force acts on the dust contained in the swirling airflow (the airflow in the swirling chamber 25b). For example, relatively bulky waste such as fiber waste and hair (hereinafter such waste is referred to as “garbage α”) is caused by this centrifugal force to cause the inner peripheral surface of the cylindrical portion 25c (the inner wall surface of the swirl chamber 25b). The inside of the swirl chamber 25b is moved downward while being pressed against.

When the waste α reaches the height of the zeroth-order opening 25e, it is separated from the swirling airflow, passes through the zeroth-order opening 25e, and is sent to the zeroth dust collection chamber 31. Then, the dust α that has entered the zero-order dust collection chamber 31 from the zero-order opening 25 e falls in the zero-order dust collection chamber 31 and is collected in the zero-order dust collection chamber 31.
That is, the waste α is sent to the zero-order dust collection chamber 31 that is a space independent of the swirl chamber 25b, and is held inside the zero-order dust collection chamber 31 with little influence of the swirling airflow.

Next, the waste β that has not entered the zero-order dust collection chamber 31 from the zero-order opening 25e (garbage with relatively small volume such as sand dust and fine fiber dust) rides on the airflow in the swirl chamber 25b, Proceeding downward while swirling in the swirl chamber 25b.
Then, the garbage β passes through the primary opening 25f. And garbage (beta) falls in the primary dust collection chamber 32, and is caught. That is, the waste β is sent to the primary dust collection chamber 32 which is a space independent of the swirl chamber 25b, and is held in the primary dust collection chamber 32 in a state where the influence of the swirl airflow is small.

When the airflow swirling in the swirl chamber 25b reaches the lowermost part of the swirl chamber 25b, the traveling direction is changed upward, and the airflow rises along the central axis of the swirl chamber 25b. Note that most of the dust α and dust β is removed from the air forming the updraft by the action described above.
The airflow (clean air) from which the waste α and the waste β are removed passes through the discharge port 24a and is discharged out of the swirl chamber 25b. The air discharged from the swirl chamber 25b passes through the discharge pipe 23b and reaches the outlet 23a. Then, the clean air sequentially passes through the outlet 23 a and the connection port 22 and is sent to the exhaust air passage 21.

When the electric blower 10 performs the suction operation, the dust α is accumulated in the zero-order dust collecting chamber 31 and the dust β is accumulated in the primary dust collecting chamber 32 as described above. These dusts α and β can be easily discarded by removing the dust collecting unit case 26 from the dust collecting unit 13.
Further, the waste α and the waste β are held in the zero-order dust collection chamber 31 and the primary dust collection chamber 32 which are spaces independent of the swirl chamber 25b. In other words, the swirling airflow separates dust and airflow from the dust-containing air without passing through the inside of the dust collection chamber where the dust is accumulated. Therefore, it is possible to prevent the odor contained in the dust from being mixed with the swirling airflow, and the air discharged from the dust collection unit 13 can be made cleaner.

Next, the exhaust air passage forming unit 17 configured inside the housing unit 12 forms the exhaust air passage 21. The exhaust air passage 21 is an air passage for guiding the air from which dust has been removed in the dust collection unit 13 to the exhaust port 50.
That is, clean air flows from the dust collection unit 13 into the exhaust air passage 21. The opening at one end of the exhaust air passage forming part 17 forms a connection port 22 with the outlet 23a.
The connection port 22 is disposed near the center in the left-right direction on the upper surface of the storage unit 12. The other end of the exhaust air passage forming portion 17 opens toward the outside of the housing unit 12. The other end of the exhaust air passage forming unit 17 forms an exhaust port 50.

Here, the exhaust air passage 21 from the connection port 22 to the exhaust port 50 will be described.
Referring to FIG. 10, an electric blower 10 is provided in the exhaust air passage 21. The electric blower 10 generates an airflow in the air passage formed in the vacuum cleaner 1. The air passage formed in the vacuum cleaner 1 includes, for example, an air passage for allowing dust-containing air to flow into the main body 6 from the outside, an air intake passage 19, an air passage formed in the dust collecting unit 13, and an exhaust air passage. 21 is included .
Further, the electric blower 10 is provided in the exhaust air passage 21 with the suction port 10a opened upward and the blower discharge port 10b opened on the side surface.
A HEPA filter 21a is provided between the connection port 22 and the electric blower 10 (upstream side of the electric blower). Further, a ULPA filter 21b is provided in front of the electric blower 10 (on the downstream side of the electric blower).

  The airflow that flows through the exhaust air passage 21 formed in this way flows downward from the connection port 22, passes through the HEPA filter 21 a, is then sucked into the suction port 10 a of the electric blower 10, and is discharged from the blower of the electric blower 10. It is ejected forward from the outlet 10b, flows downward after passing through the ULPA filter 21b, flows through the space forming the exhaust air passage 21 located below the electric blower 10, and then opens rearward. The exhaust port 50 is reached.

Thus, by providing the HEPA filter 21a with high dust collection performance on the upstream side of the electric blower 10, dust that cannot be collected by the dust collection unit 13 can be collected, and the exhaust is made cleaner. be able to.
Further, by providing the ULPA filter 21b on the downstream side of the electric blower 10, dust such as carbon emitted from the inside of the electric blower 10 can be collected, and the exhaust discharged from the electric blower 10 can be cleaned.
Note that the exhaust air passage 21 from the electric blower 10 to the exhaust port 50 has a seal structure that prevents exhaust leakage, and the exhaust from the electric blower 10 is exhausted in a concentrated manner from the exhaust port 50. Yes. Thereby, the wind speed of the exhaust gas which comes out from the exhaust port 50 can be strengthened.

Here, the exhaust port 50 will be described with reference to FIGS.
The exhaust port 50 is located behind the electric blower 10 and on the rear surface of the rear container 14. The exhaust port 50 is formed in a cylindrical shape extending in the front-rear direction, and a lattice 50a is provided at the front end so as to block the opening.
The inner shape of the exhaust port 50 is such that the connecting portion 5b of the hose 5 can be connected. That is, the exhaust port 50 is formed with an exhaust hose connection port to which the connection portion 5b can be connected. In addition, in the state where the connection portion 5 b is connected, the hose 5 and the exhaust port 50 form a series of spaces, and the exhaust gas that is the airflow discharged from the exhaust port 50 can flow into the hose 5.

  Thereby, since the exhaust airflow can be introduced into the hose 5, the exhaust flow is ejected from the attachment as a blow airflow by attaching the blow attachment 60 to the side where the connection pipe 4 of the hose 5 is connected. It can be used as a blow to blow off dust. Note that the attachment 60 may be used by replacing it with one having a different shape depending on the intended use when used as a blow. Further, instead of using the attachment 60, a blow airflow may be ejected from the direct connection pipe 4 and used.

In particular, in the present embodiment, as described above, the dust α and the dust β are collected in the zero-order dust collection chamber 31 and the primary dust collection chamber 32 which are spaces independent of the swirl chamber 25b. Therefore, the airflow flowing through the dust collection unit 13 hardly passes through the inside of the dust collection chamber where the dust is accumulated, and the odor and the like contained in the dust is not easily mixed with the exhaust flow.
That is, even if the exhaust flow used for the blow air flow is in a clean state and dust is stored in the dust collection unit 13, it can be used as blow without worrying about the smell of dust.

Further, in the vicinity of the exhaust port 50, there is provided an exhaust-side terminal receiving portion 50b serving as a connection portion that receives and connects the connection terminal 5c when the connection portion 5b of the hose 5 is connected. The exhaust-side terminal receiving portion 50b is electrically connected to the control means, and, like the intake-side terminal receiving portion 9a, the operation display portion 8 is electrically connected to the control means by being connected to the connection terminal 5c. Connecting.
As a result, the operation display unit 8 can supply power from the main body 6 (control unit), receive a control signal, and output a signal when the user presses the switch to the control unit. 10 outputs can be changed.

  That is, the user can operate the operation display unit 8 while holding the handle 7 to change the output of the electric blower 10 and adjust the strength of the exhaust air discharged from the exhaust port 50. Therefore, even when used as a blow, the user can adjust the strength of the blow while holding the handle.

Further, the connecting portion 5b is provided with an engaging means 5d. The exhaust port 50 is provided with an engagement receiving portion 50c with which the engagement means 5d is engaged. Both the engagement receiving portion 50c and the exhaust side terminal receiving portion 50b are located on the upper side in a state where the hose 5 is connected.

Further, a connection detection switch that inputs a signal to the control means when the connection portion 5b is connected may be provided at the exhaust port 50. In this way, the control means is configured to be able to detect whether or not the connection portion 5b is connected to the exhaust port 50, so that the operation of the electric blower 10 during the blow operation is the operation when performing normal cleaning. Can be different.
Further, by configuring the control means to be able to detect whether or not the connecting portion 5b is connected to the exhaust port 50, it is possible to display on the operation display portion that it is in the blow operation state.

Here, in the present embodiment, the vacuum cleaner is described as adopting a cyclone type as the dust collection method, but not limited to the cyclone type, even if other dust collection methods are adopted. Good. Moreover, it is not restricted to a canister type vacuum cleaner.
In the present embodiment, a connection detection switch that inputs a signal to the control means when the connection portion 5b is connected to the exhaust port 50 is provided. However, the connection portion 5b is provided on the intake side hose connection port 9 side. A connection detection switch may be provided for inputting a signal to the control means when connected.

Next, FIG. 14 is a block diagram showing a configuration of the electric vacuum cleaner 1 according to Embodiment 1 of the present invention. As described above, in FIG. 14, 27 is a commercial AC power source, 10 is an electric blower, and 2c is a brush motor.
FIG. 21 shows a state in which the power cord 11 provided in the electric vacuum cleaner 1 is plugged into an outlet and the electric blower 10 and the brush motor 2c are connected to a commercial AC power source. 71 and 91 are bidirectional thyristors.
The electric blower 10 and the bidirectional thyristor 71 are connected to the commercial AC power supply 27 in series. Similarly, the brush motor 2 c and the bidirectional thyristor 91 are directly connected to the commercial AC power supply 27.

Reference numeral 72 denotes a current sensor, and reference numeral 73 denotes a power supply synchronization detecting means. The current sensor 72 outputs a signal for detecting the current flowing through the electric blower 10 and the brush motor 2c. For example, the current sensor 72 includes a current transformer and a shunt resistor connected in series to the electric blower 10 and the brush motor 2c. In such a case, the current sensor 72 outputs a voltage dropped by a predetermined voltage drop method.
The power supply synchronization detecting means 73 includes a circuit for detecting a synchronization point (zero cross point) of the commercial AC power supply.

The microcomputer 80 manages various control functions of the electric vacuum cleaner 1. The microcomputer 80 includes, for example, a current detection unit 81, a control unit 82, a notification unit 83, and a connection detection unit 84.
The current detection unit 81 detects a current flowing through the electric blower 10. For example, the current detection unit 81 detects the current flowing through the electric blower 10 and the brush motor 2c based on the current value output by the current sensor.

The notification unit 83 controls the display unit 8b based on the result determined by the connection detection unit 84.
Display unit 8b, in the present invention, is described in an illuminated LED on and off in response to the "cleaning mode", "in cleaning," but (for example, may be a liquid crystal display screen and audio guidance device, and the like.), The In the invention, the display portion 8 b is provided in the connection pipe 4, but may be provided in the main body 6.
The connection detection unit 85 is provided at the exhaust port 50 (exhaust side hose connection port) and has a terminal through which an electric signal flows when it is in a connected state or is magnetic when in a connected state. There are those in which an electric signal flows due to a simple coupling state, and there are those that block light when in a connected state, or an electric signal flows due to reflection of light, for example, a mechanical detection method (such as micro SW) or a magnetic detection method It is a detection unit that detects whether the hose 5 is connected using an optical detection method (such as a magnetic sensor) or an optical detection method (such as an infrared sensor).
Further, the connection detection unit 85 may be provided in the intake side hose connection port 9 (intake side hose insertion port).
The connection detection unit 84 determines whether the hose 5 is connected to the exhaust side hose connection port based on the information of the connection detection unit 85, and receives the determination, and the control unit 82 controls the output of the electric blower 10. .

The control means 82 controls the phase angle of the voltage applied to the electric blower 10 and controls the input current to the electric blower 10 to change the output. Based on the power supply synchronization point detected by the power supply synchronization detection means 73, the control means 82 controls the phase angle so that the input current to the electric blower 10 becomes a desired value.
Further, a signal from the operation unit 8 a and a determination result of the current detection unit 81 are input to the control unit 82. For example, operation information such as input switching, start / stop and the like is input to the control unit 82 from the operation unit 8a.

Next, the operation of the present embodiment will be described with reference to the control flow shown in FIG. This control flow is executed by the control means 82.
In step 1 (hereinafter, “step” is referred to as “S”), when the power cord 11 is inserted into the commercial AC power source 27, the process proceeds to S2.

In S2, it is determined whether or not the hose 5 is inserted into the exhaust port 50 (exhaust side hose connection port). Specifically, the connection detection unit 85 detects whether the hose 5 is connected, and the connection detection unit 84 determines whether the hose 5 is inserted into the exhaust port 50 based on the information of the connection detection unit 85. Judging.
If the hose 5 is inserted in the exhaust port 50 based on the determination of the connection detection means 84, the control means 82 shifts to S3, sets the blow mode, and shifts to S4. If the hose 5 is not inserted into the exhaust port 50 based on the determination of the connection detection means 84, the control means 82 proceeds to S8, sets the normal mode, and proceeds to S9.
The normal mode is an operation process when the suction hose connection port 9 is operated by connecting the hose 5 and sucking dust from the floor surface.

As operation control in the normal mode, there are the following.
(1) Output control for changing the output by gradually increasing the input current to reach the set output when operating the electric blower 10 or increasing the output.
(2) Output control for changing the output of the electric blower 10 according to the amount of dust held in the dust collection unit 13. For example, in the case of a vacuum cleaner in which the suction force can be adjusted to “low”, “medium”, and “strong” by changing the output of the electric blower 10, the vacuum cleaner is held in the dust collecting unit 13 in the state set to “medium” operation. When the amount of dust being collected is greater than a predetermined amount, the output of the electric blower 10 is operated at 9000 [W], and when the amount of dust is less than the predetermined amount, the output of the electric blower 10 is operated at 800 [W]. That is, as the amount of dust held in the dust collection unit 13 is larger, the electric blower 10 is operated with larger electric power.
(3) Control the start / stop of the brush motor 2c.

  Control in such a normal mode is for operating with less electric power when the vacuum cleaner 1 performs a dust suction operation that is normally performed.

  Next, in S9, if a signal for starting operation is not input from the operation unit 8a, the process is terminated. In S9, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S10, the process of starting the brush motor 2c is performed, the process proceeds to S11, the process of starting the electric blower 10 is performed, and the process proceeds to S12. In S12, the display unit 8b displays that the normal mode is being performed, and the process is terminated.

  In S10, the brush motor 2c performs start-up or stop processing based on the operation in S9. In S11, the electric blower 10 operates under control corresponding to the normal mode. For example, after the electric blower 10 is activated, the output is gradually increased to control the suction force to be set. In the display process in S12, a display indicating that a normal mode, that is, a normal cleaning operation is being performed, is performed. This display is performed by indicating that normal cleaning is being performed, for example, an LED corresponding to “cleaning mode” or “cleaning” is lit.

Next, in S2, if the hose 5 is inserted into the exhaust port 50, the process proceeds to S3, the blow mode is started, and the process proceeds to S4.
In the blow mode, the hose 5 is connected to the exhaust side hose connection port formed in the exhaust port 50 to operate the electric blower 10, and the blow operation for blowing dust and the like from the target position using the exhaust is performed. Operation processing.

The blowing operation is performed in a short time compared to the dust blowing operation and the suction operation for sucking the dust. However, since the exhaust air is used, the hose is exhausted from the electric blower 10 and used as a hose. When the temperature of 5 rises and the blow operation is performed, it is not necessary to operate the brush motor 2c that operates the rotating brush 2b of the suction port body 2, and therefore it is necessary to control the operation in the blow mode. There are the following:
(1) When the electric blower 10 is operated, the output of the electric blower 10 is set so that the temperature of the hose 5 does not rise excessively with an air volume suitable for the blow operation. (The output of the electric blower 10, is operated at a power lower than the power when operated to connect the hose 5 to the intake-side hose connecting port 9 (the normal suction operation). For example, the strength of the intake side, collecting When the dust held in the dust unit 13 is more than a predetermined amount, the output of the electric blower 10 is operated at 900 [W], and when the dust is less than the predetermined amount, the output of the electric blower 10 is 800 [W]. However, the exhaust side is operated at a strong “500 W.” The reason why the exhaust side is operated at a strong “500 W” is that even when dust is held in the dust collection unit 13, the air volume is suitable for the blow operation. Set the power consumption to suppress the temperature rise of the hose 5 to such an extent that people do not burn.)
(2) Even when the dust collecting unit 13 is used in a state where dust is held, the output of the electric blower 10 is set so that the temperature of the hose 5 does not increase regardless of the amount of dust held. .
(3) Processing that does not activate the brush motor 2c that operates the rotating brush 2b of the suction port 2 that is not necessary for the blow operation is performed, and the display is also turned off. (The brush motor 2c activation notification LED is turned off.)

  Such control in the blow mode is a control for starting the electric blower 10 and blowing off dust and the like as soon as possible.

Next, in S4, if a signal for starting operation is not input from the operation unit 8a, the process is terminated. In S4, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S5, the process for stopping the brush motor 2c is performed, the process proceeds to S6, the process for starting the electric blower 10 is performed, and the process proceeds to S7. To do. In S 7, the display unit 8b, to display to the effect that performs blow mode, the process ends.

In S6, the operation of the electric blower 10 corresponds to the blow mode. For example, when the electric blower 10 is activated, control is performed to increase the output at a stretch so that the air volume suitable for use as blow is obtained.
In the display process in S7, a display indicating that the blow mode is being performed is performed. This display mode is performed by indicating that the blow mode is being performed, for example, by turning on an LED corresponding to “blow mode” or “during blow operation”. Further, a process for turning off the LED display of the motor operation that is not necessary for the blow operation is performed.

By controlling each part as described above, when performing the suction operation of sucking dust from the floor surface, which is the normal usage of the vacuum cleaner 1, also in the case of the blow mode used as blow using exhaust, Control of the electric blower 10 and the display part 8b suitable for each can be performed.
In particular, in the blow mode, it is possible to blow off dust and the like efficiently by starting up the electric blower and then increasing the output of the electric blower that becomes exhaust air suitable for blowing. (During the blow operation, the slow start process of the electric blower 10 is not performed. The slow start process is a control that increases the power consumption of the electric blower 10 step by step up to the target power consumption.)

(Embodiment 2)
Next, the operation of the second embodiment will be described with reference to the control flow shown in FIG. About the structure of the vacuum cleaner 1, since it is the same as that of Embodiment 1, description is abbreviate | omitted. This control flow is executed by the control means 82.
In S21, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S22. In S22, it is determined whether or not the hose 5 is inserted into the exhaust port 50 (exhaust side hose connection port) (the connection detection unit 85 detects whether the hose 5 is connected) and the connection detection unit 84 is connected. Based on the information of the detection unit 85, it is determined whether to perform the blow mode of S23 or the normal mode of S32.) If the hose 5 is not inserted into the exhaust port 50, the process proceeds to S32, the normal mode is started, and the process proceeds to S33.

  Next, in S33, if the signal for starting the operation is not input from the operation unit 8a, the process ends. In S33, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S34, the process of starting the brush motor 2c is performed, the process proceeds to S35, the process of starting the electric blower 10 is performed, and the process proceeds to S36. To do. In S36, the display unit 8b displays that the normal mode is being performed, and the process ends.

In S22, if the hose 5 is inserted into the exhaust port 50, the process proceeds to S23, the blow mode is started, and the process proceeds to S24.
Next, in S24, if a signal for starting operation is not input from the operation unit 8a, the process is terminated. In S24, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S25, the process of stopping the brush motor 2c is performed, the process proceeds to S26, the process of starting the electric blower 10 is performed, and the process proceeds to S27. To do. In S27, the display unit 8b displays that the blow mode is being performed, and the process proceeds to S28.

  In S28, it is determined whether an operation SW (hereinafter referred to as brush motor SW) for operating the brush motor configured in the operation unit 8a is pressed. In S28, whether or not the brush motor operation SW configured in the operation unit 8a is pressed or not, in the blow mode, the process proceeds to S29 and the stop process of the brush motor 2c is continued, and the process proceeds to S30 and the electric blower 10 is continuously started, and the process proceeds to S31. In S31, the display unit notification means continues the notification process. (In the blow mode, the brush motor operation SW process of the operation unit is ignored.)

By controlling each part as described above, when performing the suction operation of sucking dust from the floor surface, which is the normal usage of the vacuum cleaner 1, also in the case of the blow mode used as blow using exhaust, Control of the electric blower 10 and the display part 8b suitable for each can be performed.
In particular, even if the brush motor operation SW is operated during the blow operation, the stop of the brush motor 2c is continued, so that unnecessary power consumption can be prevented.

(Embodiment 3)
Next, Embodiment 3 will be described with reference to FIGS. About the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
Referring to FIG. 17, the microcomputer 80 has a storage unit 92.
The storage unit 92 stores information of the operation unit 8a and the connection detection unit 84, and is connected to the control unit 82 and the notification unit 83 so that the detection result can be output.

The operation of the third embodiment will be described with reference to the control flow shown in FIG. About the structure of the vacuum cleaner 1, since it is the same as that of Embodiment 1, description is abbreviate | omitted. This control flow is executed by the control means 82.
In S41, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S42.
In S42, it is determined whether the hose 5 is inserted into the exhaust port 50 (exhaust side hose connection port) (the connection detection unit 85 detects whether the hose 5 is connected) and the connection detection unit 84 is connected. Based on the information of the detection unit 85, it is determined whether to perform the blow mode of S43 or the normal mode of S52). If the hose 5 is not inserted into the exhaust port 50, the process proceeds to S52, the normal mode is started, and the process proceeds to S53.

Next, in S53, if the signal for starting the operation is not input from the operation unit 8a, the process ends. In S53, if a signal for starting the operation is input from the operation unit 8a, the process proceeds to S54 to determine whether the previous operation information is stored. If the previous operation information is not stored in S54, the process proceeds to S58, the brush motor 2c is activated, the process proceeds to S59, the electric blower 10 is activated, and the process proceeds to S60. In S60, the display unit 8b displays that the normal mode is being performed, and the process ends.
If the previous operation information is stored in S54, the process proceeds to S55, the brush motor 2c is operated in the previously stored operation state, and the process proceeds to S56. (If the brush motor 2c stored last time is started, the start process is performed, and if the brush motor 2c is stopped, the stop process is performed.)
In S56, it operate | moves in the driving | running state of the electric blower 10 memorize | stored last time, and transfers to S57. (If the previously memorized driving state is strong driving, it operates with strong driving. If the previously memorizing driving state is weak driving, it operates with weak driving.)
In S57, the notification process is performed in the previously stored notification state.

In S42, if the hose 5 is inserted into the exhaust port 50, the process proceeds to S43, the blow mode is started, and the process proceeds to S44.
Next, in S44, if a signal for starting operation is not input from the operation unit 8a, the process is terminated. In S44, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S45 to determine whether the previous operation information is stored. If the previous operation information is not stored in S45, the process proceeds to S49, the brush motor 2c is stopped, the process proceeds to S50, the process for starting the electric blower 10 is performed, and the process proceeds to S51. In S51, the display unit 8b displays that the normal mode is being performed, and the process ends.
If the previous operation information has been stored in S45, the process proceeds to S46, the brush motor 2c is stopped, and the process proceeds to S47.

(If the previously memorized driving state is strong driving, it operates with strong driving. If the previously memorizing driving state is weak driving, it operates with weak driving.)
In S48, the notification process is performed in the previously stored notification state.

  By having the storage means 92 as described above, it is possible to provide a vacuum cleaner that is convenient for the user. In particular, since the operation of each part can be started from the last operating state, each operation (blow and suction) can be performed without performing the setting again.

(Embodiment 4)
Next, a fourth embodiment will be described with reference to FIGS. About the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
Referring to FIG. 19, the microcomputer 80 has acceleration sensor detection means 93.
The acceleration sensor detection means 93 is connected to the control means 82 so that the detection result can be output. Further, the connection pipe 4 has an acceleration sensor 94 that detects an operation state of cleaning.
The acceleration sensor 94 is connected to the acceleration sensor detection means 93 so that the detection result can be output. The acceleration sensor detection means 93 detects the cleaning operation based on the information of the acceleration sensor 94, and the control means 82 controls the output of the electric blower 10 based on the detection result of the acceleration sensor detection means 93.

The operation of the fourth embodiment will be described with reference to the control flow shown in FIG. About the structure of the vacuum cleaner 1, since it is the same as that of Embodiment 1, description is abbreviate | omitted. This control flow is executed by the control means 82.
In S61, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S62.
In S62, it is determined whether or not the hose 5 is inserted into the exhaust port 50 (exhaust side hose connection port) (the connection detection unit 85 detects whether the hose 5 is connected) and the connection detection unit 84 is connected. Based on the information of the detection unit 85, it is determined whether to perform the blow mode of S63 or the normal mode of S72). If the hose 5 is not inserted into the exhaust port 50, the process proceeds to S72, the normal mode is started, and the process proceeds to S73.

  Next, in S73, if a signal for starting operation is not input from the operation unit 8a, the process ends.

In S76, the display unit 8b displays that the normal mode is being performed, and the process ends.

In S62, if the hose 5 is inserted in the exhaust port 50, the process proceeds to S63, the blow mode is started, and the process proceeds to S64.
Next, in S64, if the operation start signal is not input from the operation unit 8a, the process is terminated. In S64, if a signal for starting operation is input from the operation unit 8a, the process proceeds to S65 to stop the brush motor 2c, and the process proceeds to S66 to start the electric blower 10 and the process proceeds to S67. In S67, the display unit 8b displays that the blow mode is being performed, and the process proceeds to S68.

In S68, it is determined whether the operating state detected by the acceleration sensor 94 is operating or stopped. In S68, if the operation state detected by the acceleration sensor 94 is in operation, the process ends with the electric blower 10 being operated. In S68, if the operation state detected by the acceleration sensor 94 is the stop state, the process proceeds to S69.
In S <b> 69, it is determined whether or not a predetermined time has elapsed since the operation stop determination determined by the acceleration sensor detection means 93 was made. In S69, when it is determined that the operation is stopped and a predetermined time has elapsed, the process proceeds to S70.
In S70, the process which reduces the output of the electric blower 10 or stops the electric blower 10 is performed, and the process proceeds to S71. In S71, the display unit 8b displays that the output of the electric blower 10 is reduced or the electric blower 10 is stopped, and the process is terminated.
The acceleration sensor detection means 93 determines whether the operation state is in operation or is stopped, and the output of the electric blower 10 is controlled after a predetermined time has elapsed since the operation stop determination determined by the acceleration sensor detection means 93. Thus, when the operation is stopped, since the process of reducing the output of the electric blower 10 or stopping the electric blower 10 is performed, the electric blower can be used to prevent unnecessary power consumption and to use the wind of the exhaust. It is possible to prevent the temperature of the hose 5 from rising due to the exhaust heat exhausted from the exhaust gas 10. Moreover, since the output of the electric blower 10 is not reduced or stopped unless time elapses, it can be used continuously, so that a convenient vacuum cleaner can be provided.

As described above, the state in which the acceleration sensor 94 detects and determines the acceleration sensor detection means 93, by controlling the electric blower 10 and the display unit 8b, when performing an operation in a blow mode used as blowing with exhaust Since the acceleration sensor detection means 93 determines whether the operation state is operating or stopped, when the operation is stopped, the output of the electric blower 10 is reduced or the electric blower 10 is stopped, so that the temperature of the hose 5 is increased. It can be prevented, and it can be used safely and unnecessary power consumption can be prevented. Moreover, the state in which the output of the electric blower 10 is reduced or the electric blower 10 is stopped can be confirmed on the display unit 8b.

In addition, the hose 5 inserted into the exhaust port may be used when the dust is sucked into the intake side hose connection port 9 or a hose dedicated to the blow operation may be used.

(Embodiment 5)
Next, a fifth embodiment will be described with reference to FIGS. About the same structure as Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.
Referring to FIG. 21, an operation unit 8 a and a connection detection unit 85 are connected to the connection detection unit 84. The connection detection unit 84 determines whether the hose 5 is connected to the exhaust side hose connection port based on the information of the connection detection unit 85. The connection detection unit 84 receives an output signal from the operation unit 8a, and determines whether or not the operation unit 8a is operated by determining the presence or absence of this signal. (Note that signals from the operation unit 8a are output at a predetermined interval when the hose 5 is connected to the main body 6).

Referring to FIG. 22, the control means 82 controls each part as follows.
In S81, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S82. In S82, the connection detection unit 84 determines whether a signal from the operation unit 8a is input. If no signal is input, the process ends. If a signal is input, the process proceeds to S83.
In S83, the connection detection unit 84 determines whether or not a signal from the connection detection unit 85 is input. If the signal from the connection detection unit 85 is not input, the process proceeds to S85 and the normal mode is performed. If the signal from the connection detection part 85 is input, it will transfer to S84 and will perform blow mode.

The normal mode in S85 is the same process as S8. The blow mode in S84 is the same process as S3.
Each part is configured as described above, and the control means 82 controls each part, so that the operation for sucking normal dust and the operation for using exhaust as a blow function are controlled according to the intended use. The action can be performed.

(Embodiment 6)
Next, with reference to FIG. 23, the control which the control means 82 which is Embodiment 6 performs is demonstrated. In addition, since the structure of each part is the same as Embodiment 5, description is abbreviate | omitted.
In S91, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S92. In S92, the connection detection unit 84 determines whether or not a signal from the operation unit 8a is input. If a signal is input, the process proceeds to S93. If no signal is input, the process proceeds to S97, the operation unit output signal absence count is counted, and the process proceeds to S92.

In S93, the control means 82 determines whether or not the output signal of the operation unit 8a has changed from nothing to presence. When there is a change in the output signal of the operation unit 8a, the process proceeds to S94. If there is no change in the output signal of the operation unit 8a, the process ends (END) and the process proceeds to S91 again.
The determination in S93 is “Yes (YES)” if counted in S97, and “No (NO)” if not counted.
Incidentally, power on the main body 6, when starting the use, if the connection to be reliably body 6 hose 5, the output signal of the operation unit 8a "present the status" free "at the start of use Therefore, the process proceeds from S93 to S94.

In S94, the control means 82 clears the count performed in S97, and proceeds to S95.
In S95, the connection detection unit 84 determines whether or not a signal from the connection detection unit 85 is input. If no signal is input from the connection detection unit 85, the process proceeds to S98 and the normal mode is performed. If the signal from the connection detection unit 85 is input, the process proceeds to S96 and the blow mode is performed. After performing the process of S96 or S98, the process returns to S91 again.
The normal mode in S98 is the same process as S8. The blow mode in S96 is the same process as in S3.

Since the above processing is executed during the normal mode (normal operation mode for sucking dust) and the blow mode (blow operation mode), the output signal of the display unit 8a is displayed as in the fifth embodiment. Even if the mode is changed with the presence / absence of the presence / absence, even if a temporary disconnection (chattering) of the output signal from the operation unit 8a to the main body 6 occurs due to poor connection of the hose 5 to the main body 6, in S93 Since the presence or absence of a change in the output signal of the operation unit 8a and the connection of the hose are confirmed again in S95, it is possible to continue operation in the same mode without switching the operation mode.
That is, even when chattering occurs, stable operation can be performed without unexpectedly changing the operation mode each time.

(Embodiment 7)
Next, Embodiment 7 will be described with reference to FIGS.
FIG. 25 shows an output signal (operation unit output signal) of the operation unit 8a, an output signal (connection detection unit output signal) of the connection detection unit 85, and electric when the hose is connected to the exhaust port 50 (exhaust side hose connection port). It is a timing chart of the power consumption of an air blower. In addition, since the structure of each part is the same as Embodiment 6, description is abbreviate | omitted.

  In S101, when the power cord 11 is inserted into the commercial AC power supply 27, the process proceeds to S102. In S102, the connection detection unit 84 determines whether or not a signal from the operation unit 8a is input. If a signal is input, the process proceeds to S103. If no signal is input, the process proceeds to S108, the operation unit output signal absence count is counted, and the process proceeds to S102.

In S103, the control means 82 determines whether or not the output signal of the operation unit 8a has changed from nothing to presence. When there is a change in the output signal of the operation unit 8a, the process proceeds to S104. If there is no change in the output signal of the operation unit 8a, the process ends (END), and the process proceeds to S101 again.
The determination in S103 is “Yes (YES)” if counted in S108, and “No (NO)” if not counted.
Incidentally, power on the main body 6, when starting the use, if the connection to be reliably body 6 hose 5, the output signal of the operation unit 8a "present the status" free "at the start of use The process proceeds from S103 to S104.

In S104, the control means 82 clears the count performed in S108, and proceeds to S105. In S105, it is determined whether or not a predetermined time has elapsed. In the present embodiment, the predetermined time is set to 1.0 [seconds].
In S <b> 106, the connection detection unit 84 determines whether a signal from the connection detection unit 85 is input. If the signal from the connection detection unit 85 is not input, the process proceeds to S109 and the normal mode is performed. If the signal from the connection detection unit 85 is input, the process proceeds to S107 and the blow mode is performed. After performing the process of S107 or S109, the process returns to S101 again.
The normal mode in S109 is the same process as S8. The blow mode in S107 is the same process as in S3.

Since the above processing is executed while the normal mode and the blow mode (blow operation mode) are being performed, the mode is changed when there is an output signal of the display unit 8a as in the fifth embodiment. However, even if a temporary disconnection (chattering) of the output signal from the operation unit 8a to the main unit 6 occurs due to poor connection of the hose 5 to the main unit 6, whether or not the output signal of the operation unit 8a has changed in S103. Since the connection of the hose is confirmed again in S106, it is possible to continue operation in the same mode without switching the operation mode.
That is, even when chattering occurs, stable operation can be performed without unexpectedly changing the operation mode each time.
In addition, by providing a step of waiting until a predetermined time elapses in S105, it is possible to prevent a sudden change in the operation mode.

(Embodiment 8)
Next, an eighth embodiment will be described with reference to FIGS.
FIG. 26 is a flowchart showing processing when there is a change or no change from the state in which the hose 5 is connected to the exhaust port 50 (exhaust side hose connection port).
27 to 29 show an output signal (operation unit output signal) of the operation unit 8a and an output signal (connection detection unit output) of the connection detection unit 85 in a state where the hose 5 is connected to the exhaust port 50 (exhaust side hose connection port). Signal) and power consumption of the electric blower.

  In S111, the process proceeds to S112 in the blow mode. In S112, the connection detection unit 84 determines whether or not a signal from the operation unit 8a is input. If a signal is input, the process proceeds to S113. If no signal is input, the process proceeds to S118, the operation unit output signal absence count is counted, and the process proceeds to S112.

In S113, the control means 82 determines whether or not the output signal of the operation unit 8a has changed from nothing to presence. When there is a change in the output signal of the operation unit 8a, the process proceeds to S114. If there is no change in the output signal of the operation unit 8a, the process is terminated (END) and the process proceeds to S111 again.
The determination in S113 is “Yes (YES)” if counted in S118, and “No (NO)” if not counted.

In S114, the control means 82 clears the count performed in S118, and proceeds to S115. In S115, it is determined whether or not a predetermined time has elapsed. In the present embodiment, the predetermined time in S115 is set to 1.0 [seconds].
In S116, the connection detection unit 84 determines whether a signal from the connection detection unit 85 is input. If no signal is input from the connection detection unit 85, the process proceeds to S119 and the normal mode is performed. If the signal from the connection detection unit 85 is input, the process proceeds to S117 and the blow mode is performed. After performing the process of S117 or S119, the process returns to S111 again.
Incidentally, S1 1 9 normal mode is similar to the processing of S8. Further, S1 1 7 blow mode is similar to the processing of S3.

Reference is now made to FIG. FIG. 27 illustrates a state in which the connection detection unit output signal is turned off while the hose 5 is operating in a state of being connected to the exhaust port 50. Specifically, it is a timing chart in a state where a detection failure occurs in the connection detection unit 85 during the operation in the blow mode.
This timing chart is a flow of S111 → S112 → S113 → END (return to S111 again) in the flowchart of FIG.

That is, even when the signal of the connection detection unit 85 is turned off, if the output signal of the operation unit 8a does not change from “No” to “Yes” (S113), the process continues to operate in the mode as it is. ing.
In this way, the control means 82 performs processing that does not change to the normal mode even when the connection detection unit output signal is turned OFF during the blow mode. Thereby, the output of the electric blower unintended by the user is not changed.

Reference is now made to FIG. FIG. 28 is a timing chart showing a state in which the hose 5 is operated with the hose 5 connected to the exhaust port 50, the hose 5 is disconnected from the exhaust port 50 and connected to the exhaust port 50 again within a predetermined time. In the present embodiment, the predetermined time referred to here is set to 1 second.
This timing chart is a flow of S111 → S112 → S113 → S114 → S115 → S116 → S117 → END (return to S111 again) in the flowchart of FIG.

In this way, the control means 82 sets the connection detection unit output signal to ON within a predetermined time even when the connection detection unit output signal and the operation unit output signal are turned OFF during the blow mode. If so, the process not changing to the normal mode is performed. Thereby, the output of the electric blower unintended by the user is not changed.
Such a state assumes, for example, a case where the hose 5 is disconnected from the exhaust port 50 for a moment and then reattached.

  Incidentally, regarding “* 1” in FIG. 28, when the hose 5 is disconnected from the exhaust port 50, the reason why the connection detection unit output signal is turned off earlier than the timing at which the operation unit output signal is interrupted is that This is because the connection terminal 5c is separated from the exhaust-side terminal receiving part 50b after the timing when the connection detection part 85 is turned off when it is removed from the exhaust port 50.

Regarding “* 2”, when connecting the hose 5 to the exhaust port 50, the reason why the connection detection unit output signal is turned on later than the timing at which the operation unit output signal is input is that the hose 5 is exhausted. This is because the connection terminal 5c is connected to the exhaust side terminal receiving part 50b earlier than the timing when the connection detection part 85 is turned on when connecting to the port 50.
In this way, the control means 82 performs processing that does not change to the normal mode even when the connection detection unit output signal is turned OFF during the blow mode. Thereby, the output of the electric blower unintended by the user is not changed.

Still referring to FIG. FIG. 29 shows a state in which the hose 5 is operated in a state where it is connected to the exhaust port 50, the hose 5 is disconnected from the exhaust port 50 on the way, and the hose 5 is connected to the intake side hose connection port 9.
This timing chart is a flow of S111 → S112 → S113 → S114 → S115 → S116 → S119 → END (return to S111 again) in the flowchart of FIG.

As described above, the control means 82 removes the hose 5 from the exhaust port 50 during the blow mode so that the connection detection unit output signal and the operation unit output signal are turned off. If the operation unit output signal is input by connecting 5 to the intake-side hose connection port 9, a process for changing to the normal mode is performed.
In particular, since processing for changing to the normal mode is performed after a predetermined time (in this embodiment, 1 second) has elapsed since the operation display unit output signal was detected in S115, the hose 5 is connected to the intake hose connection port 9. Immediately after connection, the output of the electric blower can be prevented from increasing.

(Other forms)
The embodiment described above includes the following configurations. Note that the description of the same configuration as that described in Embodiment 1 is omitted.
1 to 4 and 10 to 13, the vacuum cleaner 1 has a main body 6 in which an electric blower 70 is built. The main body 6 has a main body handle 100 for lifting the main body 6. The main body handle 100 is connected to the left and right central portion of the upper surface of the main body 6 and has a grip portion 101 that is long in the front-rear direction.

Further, an intake side hose connection port 9 that opens toward the front is formed on the front wall surface 6 a of the main body 6. A hose 5 is connected to the intake side hose connection port 9. The hose 5 has a connection portion 5b, is flexible or bendable, and the connection portion 5b arbitrarily connects to the intake-side hose connection port 9.
The intake side hose connection port 9 is formed upward so as to increase toward the front side of the main body 6. That is, the direction in which the opening of the intake hose connection port 9 is directed is a predetermined angle θ1 and obliquely upward with respect to the horizontal direction.

Further, the wall surface 6b after the body 6, an exhaust port 50 for discharging air sucked by the electric blower 70 (the exhaust) from the main body 6 is formed.
The exhaust port 50 is connected to the inside of the hose 5 by connecting the connecting portion 5b. That is, in a state where the hose 5 is connected to the exhaust port 50, the exhaust gas flows into the hose 5 from the exhaust port 50 and is discharged from the side where the hose 5 is not connected (the side where the connection pipe 4 is connected). Is done.

An attachment 60 is attached to the opening of the hose 5 on the side not connected to the exhaust port 50. This attachment 60 is used for blow work, can discharge an exhaust flow from the attachment as a blow air flow, and can be used as a blow to blow off dust.
The direction of the exhaust port 50 coincides with a horizontal line that horizontally crosses the main body 6 or is set within a range up to a predetermined angle θ2 from the horizontal line. Further, the exhaust port 50 is located below the main body handle 100. It should be noted that the exhaust port 50 and the main body handle 100 may be slightly overlapped with each other, and the left and right centers of the respective portions may be slightly shifted.
Further, wheels 18 for moving the main body on the floor surface are arranged on both the left and right sides of the main body 6.

Since it is configured as described above, when the hose 5 is inserted and connected to the intake side hose connection port 9 formed on the front wall surface 6a of the main body 6, and conversely, the hose 5 is connected to the intake side hose of the main body 6. when pulling from the connecting port 9, but the direction of the force is a linear direction extending through the main body 6 in the longitudinal direction as indicated by the arrow X, when this, as body 6 does not inadvertently move, the front-rear direction long grip By holding the main body handle 100 having 101, it can be pressed.

Further, when the hose 5 is inserted and connected to the exhaust port 50 formed on the rear wall surface (rear surface) 6b of the main body 6 and when the hose 5 is pulled out from the exhaust port 50, the direction of the force is an arrow. Although it is a straight direction that penetrates the main body 6 in the front-rear direction like Y, also in this case, by gripping the main body handle 100 having the long grip portion 101 in the front-rear direction so as not to move the main body 6 carelessly. Can hold down.
Since the main body 6 can be pressed as described above, the wheel 18 provided for smoothly running the main body 6 on the surface to be cleaned such as the floor during normal cleaning is not possible in an oblique direction or a lateral direction. It can be prevented from being moved, and it does not cause a problem of scratching the floor surface.

Further, since the suction side hose connection port 9 is formed upward on the front surface of the main body 6, when the user inserts and connects the hose 5 before or during the start of cleaning, and conversely When pulling out, it can be done in an easy posture without bending down.
Further, since the direction of the exhaust port 50 is set in the horizontal direction, that is, in the direction of the side, or in the range from the position upward to the predetermined angle θ2, the exhaust port 50 is used when the blow function is not used. Even if the air after dust collection is blown out vigorously from 50, it is possible to suppress the dust on the floor surface from being rolled up by such an exhaust flow.

Further, a hose 5, while still connected to an exhaust port 50 of the body 6, the hose 5 is pulled, even if the event body 6 is moved, the position of the exhaust port 50 of the tensile force acts, the body Since the wheel 18 rolls in the direction opposite to the traveling direction during normal cleaning, the vacuum cleaner main body 6 can be prevented from being tilted and tilted. For this reason, the user can efficiently perform the cleaning work using the blow function.

Next, the main body 6 has a cyclone type dust collection unit 13 that separates dust by rotating dust-containing air sucked by the electric blower 70 at a high speed in a cylindrical passage.
The intake hose connection port 9 communicating with the dust collection unit 13 communicates with the upper part of the cylindrical passage.
With this configuration, dust can be collected from below the cyclone type dust collection unit 13, so that a dust collection volume can be secured and long-time cleaning can be handled.
