When the reed switch 41 is closed, the control means 35 of the cleaner body 12 recognizes that the auxiliary operation section 82 is operated while the cleaner body 12 is attached to the cleaning auxiliary body 13. Then, even if the slide switch 44 of the main body operation unit 46 is operated, it is not recognized, and the electric blower 25 is driven to a predetermined drive state in response to the operation of the auxiliary operation unit 82. By driving the electric blower 25, dust is sucked together with air from a communication suction port (not shown) of the suction port body 70 of the cleaning auxiliary body 13 which communicates with the suction port 57 of the cleaner body 12, and the suction port 57 is passed through the communication pipe 68. Inhale from and clean.

On the other hand, when removing the cleaner body 12 from the cleaning auxiliary body 13, first, as shown in FIG.
The switch knob 81 of 82 is moved to the OFF side to stop the drive of the electric blower 25. That is, the switch knob
When the sliding body 85 is slid together with the connecting portion 84 by moving 81 to the OFF side, and as shown in FIG. 7, the riding bulging portion 75 of the balance portion 76 in a state of being engaged with the escape portion 86 of the sliding body 85. Of the reed switch 41 of the cleaner body 12 against the bias of the coil spring 77 by the magnet 74 of the balance unit 76.
The reed switch 41 is opened by rotating the electric blower 25 in a direction away from the electric blower 25.

Then, as shown in FIG. 8, the second button portion 104 of the second clamp portion 91 of the support portion 88 is pushed against the bias of the coil spring 105, and the third insertion hole of the body portion 62 is pushed.
Pull out the positioning pin 103 to be inserted into 109,
The body portion 62 is inserted into the fitting insertion portion 65 of the floor surface cleaning portion 61 while holding 3 and the end surface of the grip portion 63 is expanded and contracted until it comes into contact with the support portion 88. In this state, the switch knob of the auxiliary operation unit 82
Even when the electric blower 25 is driven to the ON side without moving 81 to the OFF side, the projection 83 of the switch knob 81 contacts the end surface of the support 88 and is pushed into the grip 63. Then, the switch knob 81 is moved to the OFF side and the drive of the electric blower 25 is stopped. Next, by releasing the pushing of the second button portion 104, the second button portion 104 is rotated by the urging of the coil spring 105,
The positioning pin portion 103 is inserted into the third insertion hole 109 of the body portion 62 to restrict the movement of the body portion 62.

Thereafter, as shown in FIG. 9, the first button portion 93 of the first clamp portion 90 is pushed in against the bias of the coil spring 94, and the guide pin 99 of the first button portion 93 is moved to the first position. The holding claw portion 95 is rotated while being inserted into the first insertion hole 107 of the body portion 62 through the first fitting insertion hole 98. In this state, the grasping portion 18 of the cleaner body 12 is held, and the cleaner body 12 is pulled out in a direction away from the body portion 64 of the floor cleaning portion 61 of the cleaning auxiliary body 13. At the time of this withdrawal, since the lower end edge of the rotated holding claw portion 95 is in an inclined state, the holding claw portion 95 is guided by the edge of the mounting recess 42 of the cleaner body 12, and the holding claw portion 95 is an end surface of the support portion 88. Is retracted against the bias of the biasing means (not shown), and the vacuum cleaner body 12 is unlocked. Then, the cleaner body 12 is removed by pulling it out from the communication pipe 68 to be inserted.

By the way, during cleaning with the cleaner body 12 attached to the cleaning auxiliary body 13, furniture or the like comes into contact with the body operation section 46 of the cleaner body 12 and carelessly operates the operation knob 48 of the body operation section 46. Even if is operated, the control means 35 does not recognize the operation of the main body operation part 46 due to the closing of the reed switch 41, so that the erroneous operation in which the drive state of the electric blower 25 is changed does not occur. Further, when the cleaning knob body 12 is attached to the cleaning auxiliary body 13 and the switch knob 81 of the auxiliary operation portion 82 is located on the OFF side and the reed switch 41 is opened, furniture or the like is not displayed on the main body operation portion 46. Even if the operating knob 48 of the main body operating portion 46 is inadvertently operated by abutting, the sliding claw portion 56 of the slide switch 44 of the main body operating portion 46 is safe unless the safety lever 45 is grasped. Since it is not locked to the click portion 55 of the lever portion 54 of the lever 45, the operating element 49 is immediately moved to the state in which the slide switch 44 is opened by the urging of the coil spring 52. Since the electric blower 25 is not maintained and the electric blower 25 is not driven, the malfunction of the electric blower 25 being carelessly driven does not occur.

As described above, the control means 35 drives the electric blower 25 in response to the setting operation of the auxiliary operation section 82 of the cleaning auxiliary body 13 only when the cleaner body 12 is attached to the cleaning auxiliary body 13. When the cleaner main body 12 is detached from the cleaning auxiliary body 13 and is cleaned only by the cleaner main body 12, the electric blower 25 of the electric blower 25 corresponding to the setting operation of the main body operation unit 46 of the cleaner main body 12 is controlled. In order to control the drive, for example, even if the main body operation unit 46 of the cleaner main body 12 attached to the cleaning auxiliary body 13 is operated during cleaning, the driving state of the electric blower 25 is not controlled and the auxiliary operation of the cleaning auxiliary body 13 is controlled. Since the setting contents by the setting operation of the portion 82 are maintained, it is possible to prevent an erroneous operation in which the driving state of the electric blower 25 is inadvertently changed, and it is possible to improve the cleaning workability.

Further, since the reed switch 41 is opened and closed to detect the setting contents set by the auxiliary operation portion 82 when the cleaning auxiliary body 13 is attached to the cleaning auxiliary body 13, for example, the contactless structure is adopted. For example, the control unit 35 of the cleaner body 12 recognizes the setting content set by the setting operation of the auxiliary operation unit 82 by bringing the contact provided on the cleaner body 12 into contact with the contact provided on the cleaning auxiliary body 13 at the time of wearing. With respect to the contact structure that is driven and controlled by means of the above, there is no risk of malfunction due to poor contact due to contact wear, and cleaning workability can be improved.

Further, the reed switch 41 is used to control the drive of the electric blower 25 by opening and closing by the strength of the magnetism depending on the position of the magnet 74 that moves in response to the setting operation of the auxiliary operation unit 82. A simple structure can be obtained in which the setting contents of 82 can be recognized with a contactless structure.

Further, the body portion 62 is expanded and contracted to make the auxiliary operation portion 82.
Since the configuration is such that the cleaner body 12 cannot be attached to and detached from the cleaning auxiliary body 13 unless the switch knob 81 of the is located on the OFF side, the auxiliary operation unit 82 is operated when the cleaner body 12 is attached and detached, and careless electric operation is performed. The blower 25 can be prevented from being driven by a simple structure, and cleaning workability can be improved.

In the above embodiment, the reed switch 41 is operated by operating the switch knob 81 of the auxiliary operation section 82.
Although the configuration in which the drive control of the electric blower 25 is performed by opening and closing is described, when the cleaning is performed only by the cleaner body 12, the reed switch is provided because the magnetic member is located near the cleaner body 12. 41 closed and electric blower
In order to prevent 25 from driving, vacuum cleaner body
Reed switch 41 only when 12 is attached to cleaning aid 13
It is preferable that the control means 35 recognizes the closing of the above and performs drive control. That is, a switch or the like for separately detecting whether or not the cleaner body 12 is attached to the cleaning auxiliary body 13 is provided, and the cleaner body 12 with the switch closed is attached to the cleaning auxiliary body 13. It is advisable to provide a structure for recognizing the closing of the reed switch 41 by recognizing the state by the control means 35.

Also, the description has been given by operating the switch knob 81 of the auxiliary operation section 82 to move the magnet 74 to open / close the reed switch 41 and drive the electric blower 25. However, in addition to the case of magnetism, sound waves, radio waves, infrared rays are used. Such as a non-contact structure for recognizing the setting contents of the auxiliary operating unit 82 by wireless such as light, or a contact structure for electrically recognizing the setting contents of the auxiliary operating unit 82 by providing contacts. Good.

Further, the setting contents of the auxiliary operating portion 82 are not limited to ON and OFF depending on the method of transmitting the operating contents and the drive control method.

Then, the cleaning auxiliary body 13 is provided with a communication pipe 68 to which the suction port 57 of the cleaner body 12 is connected and a suction port body 70,
Although the configuration for cleaning via the suction port body 70 has been described,
The cleaning auxiliary body 13 is not provided with the communication pipe 68 and the suction port body 70, and the cleaner body 12 is equipped with a suction port body having a separate communication pipe 68, and the cleaner body 12 with the suction port body is mounted. A so-called handy type cleaner main body can be attached to and detached from the cleaning auxiliary body, and the cleaning mode can be changed depending on the attachment / detachment state of the cleaning auxiliary body.

That is, the cleaner body 12 is attached to the cleaning auxiliary body 13, and the connecting male terminals 125, 125 of the cleaner auxiliary body 13 are connected to the connecting female terminals 116, 116 of the cleaner body 12 so that the connecting female terminals 116, 11 are connected.
6 is closed, or the vacuum cleaner body 12 is
It is not attached to and the connection female terminals 116, 116 are judged to be open. Then, when it is determined that the cleaner main body 12 is not attached to the cleaning auxiliary body 13 because the connection female terminals 116, 116 are opened, it is determined whether or not the main body operation unit 110 is connected (step 2). That is, the control means 35 determines whether or not the predetermined current value due to the resistance R1 of the first touch switch 111 is detected without operating the various switches 112, 113, 114. And
When the predetermined current value due to the resistance R1 of the first touch switch 111 is not detected, for example, when the cleaner main body 12 is attached to or detached from the cleaning auxiliary body 13, various types of the first touch switch 111 of the main body operation unit 110 are attached. Various switches 11 such as when one of the switches 112, 113, 114 is operated and removed.
It is determined that 2, 113, 114 are being operated, noise is being input, or wire is in an abnormal state, the standby state is entered, and the process returns to step 1 again, and the cleaner body 12 and the cleaning aid 13 The cleaning mode confirmation standby state and the setting operation standby state, which are the connection states with, are set.

In step 1, electric current flows through the connecting female terminals 116, 116 of the cleaner body 12 to connect the connecting male terminals 125, 125 of the cleaning auxiliary body 13 to close the connecting female terminals 116, 116. When it is determined that the cleaner body 12 is attached to the cleaning auxiliary body 13, it is determined whether or not the stop switch 122 of the second touch switch 121 is operated and a predetermined current value by the resistor R6 is detected.

Then, when the predetermined current value by the resistor R2 is detected, it is determined that the stop switch 112 has been operated, and the control means 35 controls to stop the electric blower 25 (step 12),
When the predetermined current value of R2 is not detected, it is determined whether or not the weak drive switch 113 of the first touch switch 111 is operated to detect the predetermined current value of the resistor R3 (step 13). .

Further, when it is determined that the weak drive switch 113 is operated by detecting the predetermined current value by the resistor R3, the control means 35 drives the electric blower 25 weakly (step 14), and then the step. Returning to 1, the cleaning mode confirmation standby state and the setting operation standby state are entered. Further, when the predetermined current value by the resistor R3 is not detected, it is determined whether or not the strong drive switch 114 of the first touch switch 111 is operated and the predetermined current value by the resistor R4 is detected ( When it is determined that the strong drive switch 114 has been operated by detecting a predetermined current value by the resistor R4 in step 15), the control means 35 strongly drives the electric blower 25 (step 16), and then step 1 Then, the process returns to the cleaning mode confirmation standby state and the setting operation standby state. Further, when the predetermined current value by the resistor R4 is not detected, it is judged as noise and it is judged whether or not the electric blower 25 is in the driving state (step 17), and when the electric blower 25 is being driven. Is the step
When the electric blower 25 is stopped at 12 and it is determined that the electric blower 25 is not driven, the process returns to step 1 to enter the cleaning mode confirmation standby state and the setting operation standby state.

Here, when the cleaner body 12 is attached to or detached from the cleaning assisting body 13, the connection state of the auxiliary operating section 120 and the main body operating section 110 is recognized, and the various switches 112, 113, 114 are not operated and the resistance R1 is not operated. The standby state for the setting operation is set only when a predetermined current value is detected. If the predetermined current value is not detected, it is determined that there is an abnormal state or the auxiliary operation unit 120 and the main body operation unit 110 are inadvertently operated while the cleaner main body 12 is attached to or detached from the cleaning auxiliary body 13 The blower 25 is stopped to enter the standby state. Since there is a time lag between this standby state and the recognition of the next state, the stopped state will be maintained for a predetermined time.Therefore, careless operation should be performed during and immediately after attaching / detaching the cleaner body 12. It is possible to prevent erroneous operation of the electric blower 25 being driven by the set contents that have been set, and improve the cleaning workability.

Further, the main body operating section 110 and the auxiliary operating section 12

Next, still another embodiment will be described with reference to FIGS. 18 and 19.

The embodiment shown in FIGS. 18 and 19 is different from the embodiment shown in FIGS. 1 to 11 in that, in addition to the reed switch 41 located in the positioning recess 40, the cleaning assisting body 13 of the cleaner body 12 is provided. A reed switch 131 as a connection recognizing means is provided on the bottom surface of the main body 64 of the cleaning auxiliary body 13 while a magnet 132, for example, is provided on the main body 64 of the cleaning auxiliary body 13 corresponding to the connection recognizing means. Slide switch 44
A three-contact slide switch 130 is used as the above.

Further, instead of the sliding body 85 and the balance section 76 of the embodiment shown in FIGS. 1 to 11, a magnet 74 that moves with the movement of the connecting portion 84 is integrally formed at the tip of the connecting portion 84. Set up.

Next, the relationship between the main body operating portion 46 and the auxiliary operating portion 82 of the embodiment shown in FIGS. 18 and 19 is shown in FIG.
