The power supply means 32 for supplying the current and the current detection means 34 for detecting the current from the operation means 26 are provided. Further, the power supply means 32 outputs a constant voltage from the constant voltage terminal regulator 36 and the capacitor 37. The current detecting means 34 is composed of resistors 46, 47, 48 and capacitors 49, 50, and detects the current value of the operating means 26.

Further, the control means 25 includes the two-wire transmission lines 51, 52.
It is connected to the operating means 26 via. This operation means
In the 26, a current limiting resistor 56 for detecting the connection of the hose 2 is connected in series between the two-wire transmission lines 51 and 52. Further, in parallel with the resistor 56, a series circuit of a normally open switch 57 and a resistor 58 operated by the stop setting button 12, a normally open switch 59 operated by the output reduction setting button 13, and Series circuit of resistor 60, normally open switch 61 and resistor operated by button 14 for setting output increase
A series circuit of 62, a normally open switch 63 operated by the button 16 for the power brush B and a series circuit of a resistor 64 are connected. The resistance values of the resistors 58, 60, 62, 64 are set to different resistance values.

The microcomputer 31 is shown in FIG.
It has the threshold value shown in (c).

This threshold value is a threshold value i ₁ when the hose 2 is simply connected, and a threshold value when the stop setting button 12 is operated to close the normally open switch 57 and a current flows through the resistor 58. The threshold value i _{2 which} is slightly larger than i ₁ , the button 13 for setting the output reduction is operated, the normally open switch 59 is closed, and the resistance 60 is set.
Slightly larger threshold i ₃ than the threshold value i ₂ If the current flows through the slightly larger threshold than the threshold value i ₃ When closed switch 61 of the normally open button 14 is operated for increased output setting current flows through the resistor 62 i _4, when the normally open switch 63 button 16 is operated for power brush B is closed current flows through the resistor 64 is set to the threshold i ₅ slightly greater than the threshold value i _4. Further, a current value larger than the current value when the operation means 26 is short-circuited is maintained as the end state threshold value i ₆ in the previous state.

Next, a specific operation will be described with reference to the time chart shown in FIG. 5 and the flow chart shown in FIG.

First, as shown in FIG. 6, the output decrease setting time t = 0, the output increase setting time s = 0, and a = 0 for not recognizing are set (step 1), and the current detecting means 34 is operated. Read the current from the means 26 (step 2), threshold i ₁
The presence or absence of the above current is detected to detect whether or not the hose 2 is connected (step 3). If the current is below the threshold i ₁ ,
Since the space between the two-wire transmission lines 51 and 52 is open, it is determined that the hose 2 is disconnected, and the electric blower F is stopped 1 second later (step 4), and a = 0 indicating that it is not recognized is set. (Step 5) and returns to step 1. When the current detection means 34 detects a current equal to or greater than the threshold value i ₁ , it is determined that the hose 2 is connected, and the process proceeds to the next step.

Then, it is detected whether or not there is an input pulse of the button 12 for stop setting (step 6), that is, FIG.
And equal to or less than a threshold value i ₂ exceeds the threshold value i ₁ of (c), the case of less than the threshold value i ₂ exceeds the threshold value i ₁ determines that the button 12 for stop setting is operated, FIG. 5 (A),
The electric blower F and the power brush B shown in (b) are stopped (step 7), a = 0 indicating that the recognition is not made is set (step 8), and the process returns to step 1.

Further, if it is determined not the threshold value i ₂ or less in Step 6, to detect whether there is an input pulse button 13 for output reduction set (step 9), namely a threshold value exceeds a threshold value i ₂ i ₃ or less, and if the threshold i ₂ is exceeded and the threshold i ₃ or less, it is determined that the output reduction setting button 13 has been operated, and output reduction processing for reducing the output of the electric blower F is performed. Do (Step 10), Step 1
Return to.

[0024] When it is determined not the threshold value i ₃ or less in Step 9, to detect whether there is an input pulse button 14 for power augmentation set (step 11), i.e., the threshold value exceeds a threshold value i ₃ i ₄ or less, and if the threshold i ₃ is exceeded and the threshold i ₄ or less, it is determined that the output increase setting button 14 has been operated, and output increase processing for increasing the output of the electric blower F is performed. Perform (step 12) and return to step 1.

Further, if it is determined not the threshold value i ₄ or less in the step 11, detects whether or not there is an input pulse button 16 for power brush B (step 13), i.e. the exceeding threshold threshold i ₄ It determines whether or not i is ₅ or less, in the case of less than the threshold value i ₅ exceeds the threshold value i ₄ determines that the button 16 for power brush B is operated, is operated power brush B (step 14), step Return to 1. Incidentally. When the button 16 for the power brush B is operated and the electric blower F is not driven, the electric blower F is also driven in the automatic state.

When it is determined in step 13 that the threshold value is not equal to or less than the threshold value i ₅ , it is determined that the threshold value is the extreme threshold value, and the process returns to step 1 to circulate through the loop and enter the standby state to maintain the previous operation.

Thus, in the case of the extreme threshold, by maintaining the previous operation, when external noise or short-circuiting of the operating means 26 occurs as shown by the pulse N in FIG. 5 (c). Generally, since the maximum threshold value is reached, the previous operation is maintained without external noise and malfunction even when the operating means 26 is short-circuited.

Then, when the control of the output reduction processing is selected, the operation of the flowchart shown in FIG. 7 is performed.

First, it is judged whether or not a = 0, which means that it is not recognized (step 21). If a = 0, the output of the electric blower F is set to P = 4 (step 22). The output reduction setting time t = 0 is set, and the timer is counted at t = 0 (step 23). Then, the output increase setting time s =
0 is set (step 24), a = 1 indicating the recognition is set (step 25), and the process proceeds.

The output P of the electric blower F is 7>6>
The relationship of 5>4>3>2> 1 is set, and the plurality of output states are stored in the storage means (not shown) in the control means 25.

If it is judged in step 21 that a = 0, which means that the output is not recognized, that is, if it is determined that a = 1, which means that the timer has already been timed at t = 0 and that the recognition has been made, the output reduction setting time is set. It is determined whether or not t = 0 (step 26), and when t = 0, it is determined whether or not the output P = 1 of the electric blower F (step 27), and if P = 1. Sets a = 1, which means that it has been recognized (step 25),
If P = 1 is not set, P = P-1 is set (step 28), the output reduction setting time t = 0 is set, and the timer is counted at t = 0 (step 23). Then, the output increase setting time s = 0 is set (step 24), a = 1 that is the recognition result is set (step 25), and the process proceeds to the next step.

Further, in step 26, the output reduction setting time t
If not equal to 0, it is determined whether t <0.5 seconds (step 29). If t <0.5 seconds is not satisfied, that is, t ≧ 0.5 seconds, the step is performed. Go to 27 and below. Then, when t <0.5 seconds, it is determined whether or not the output P ≧ 3 of the electric blower F (step 30),
When P ≧ 3 is not satisfied, it is determined whether P = 1 (step 31). Further, if P = 1, the process proceeds to step 25. If P = 1 is not satisfied, P = P-1 is set (step 32) and then the process proceeds to step 25. And
If P ≧ 3 in step 30, P = P−2 is set (step 33), which means that it is recognized in step 25 a =
Set 1 and proceed to the next.

Next, when the control of the output increasing process is selected, the operation of the flowchart shown in FIG. 8 is performed.

First, it is judged whether or not a = 0, which means that it is not recognized, (step 41). If a = 0, the output P of the electric blower F is set to P = 4 (step 42), and the output is set. The increase setting time s is set to s = 0, and the timer is counted at s = 0 (step 43). Then, the output reduction setting time t = 0 is set (step 44), a = 1 indicating the recognition is set (step 45), and the routine proceeds.

If it is judged in step 41 that a = 0, which means that the output is not recognized, that is, if it is judged that a = 1, which means that the timer has already been counted at s = 0, the output increase setting time is set. It is determined whether s = 0 (step 46), and when s = 0, it is determined whether the output P = 7 of the electric blower F (step 47). When P = 7, Sets a = 1, which means that it has been recognized (step 45),
If P = 7 is not set, P = P + 1 is set (step 48), the output increase setting time s = 0 is set, and the timer is timed at s = 0 (step 43). Then, the output reduction setting time t = 0 is set (step 44), a = 1 indicating the recognition is set (step 45), and the routine proceeds.

In step 46, the output increase setting time s
If = 0, it is determined whether s <0.5 seconds (step 49). If s <0.5 seconds, that is, if s ≧ 0.5 seconds, then step Go to 47 and below. Then, if s <0.5 seconds, it is determined whether or not the output P ≦ 5 of the electric blower F (step 50),
When P ≦ 5 is not satisfied, it is determined whether P = 7 (step 51). Further, if P = 7, the process proceeds to step 45. If P = 7 is not satisfied, P = P + 1 is set (step 52) and then the process proceeds to step 45. And
If P ≦ 5 at step 50, P = P + 2 is set (step 53), which means that it is recognized at step 45 a =
Set 1 and proceed to the next.

For example, in an electric vacuum cleaner having a strong, medium, weak, and automatic operation section, when any one of the operation sections is operated a plurality of times within a predetermined time, it is set to automatic (a predetermined drive state). You can also do so.

Next, another embodiment will be described.

In the embodiment shown in FIGS. 1 to 8, the configuration for reducing and increasing the output of the electric blower has been described. However, when the same setting is made within a predetermined time, the electric blower is set to a specific state. That is, as shown in FIG. 9, for example, the electric blower promptly outputs the minimum output P.
= 1 or the configuration in which the electric blower is set to the maximum output P = 7 as shown in FIG.

When the control of the output reduction processing is selected by the operating means 26, as shown in the flow chart of FIG. 9, first, it is judged whether or not a = 0, which means that it is not recognized (step 61). When a = 0, the output P of the electric blower F is set to P = 4 (step 62), the output reduction setting time t = 0 is set, and the timer is counted at t = 0 (step 63). Then, the output increase setting time s = 0 is set (step 64), a = 1 that indicates the recognition is set (step 65), and the process proceeds.

If it is determined in step 61 that a = 0, which means that the output is not recognized, that is, that a = 1, which means that the timer has already been counted at t = 0 and that the recognition has been made, the output reduction setting time is set. It is determined whether t = 0 (step 66). If t = 0, it is determined whether the output P of the electric blower F is P = 1 (step 67). If P = 1, Sets a = 1, which is the recognition result (step 65),
If P = 1 is not set, P = P-1 is set (step 68), the output reduction setting time t = 0 is set, and the timer is counted at t = 0 (step 63). Then, the output increase setting time s = 0 is set (step 64), a = 1 that indicates the recognition is set (step 65), and the process proceeds.

Further, in step 66, the output reduction setting time t
If not equal to 0, it is determined whether t <0.5 seconds (step 69). When t <0.5 seconds is not satisfied, that is, when t ≧ 0.5 seconds, the process proceeds to step 67 and thereafter. When t <0.5 seconds, it is determined whether or not the output P of the electric blower F is 1 (step 70),
If P = 1, the process proceeds to step 65. If P = 1 is not set, P = 1 is set (step 71), and then a = 1, which means that the recognition is made in step 65, is set. Continue to the next.

On the other hand, when the control of the output increasing process is selected by the operating means 26, first, as shown in the flow chart of FIG. 10, it is judged whether or not a = 0, which means that it is not recognized ( Step 81), a = 0 indicating that the recognition is not performed.
In the case of, the output of the electric blower F is set to P = 4 (step 82), and the output increase setting time s = 0 is set,
When s = 0, the timer counts (step 83). Then, the output reduction setting time t = 0 is set (step 84), a = 1 indicating the recognition is set (step 85), and the routine proceeds.

If it is judged in step 81 that a = 0, which means that the output is not recognized, that is, if it is judged that a = 1, which means that the timer has already been counted at s = 0, the output increase setting time is set. It is determined whether or not s = 0 (step 86), and when s = 0, it is determined whether or not the output P = 7 of the electric blower F (step 87). If P = 7, Sets a = 1 (step 85), if not P = 7, sets P = P + 1 (step 88), sets the output increase setting time s = 0, and sets timer s = 0. Time is counted (step 83). Then, the output reduction setting time t = 0 is set (step 84), a = 1 indicating the recognition is set (step 85), and the routine proceeds.

In step 86, the output increase setting time s
If = 0, it is determined whether s <0.5 seconds (step 89). If s <0.5 seconds, that is, if s ≧ 0.5 seconds, the process proceeds to step 87 and thereafter. When s <0.5 seconds, it is determined whether or not the output P of the electric blower F = 7 (step 90),
If P = 7, the process proceeds to step 85. If P = 7 is not set, P = 7 is set (step 91), and then a = 1, which is the recognition result in step 85, is set. Continue to the next.

Thus, according to the embodiments shown in FIGS. 1 to 8 and the embodiments shown in FIGS. 9 and 10,
The control means 25 includes various setting buttons 12, 13, 14, of the operation means 26.
A threshold value is set stepwise for each state set by 16, and the electric blower F is controlled according to this threshold value, and the operation means
26, a predetermined time, that is, the output reduction setting time t <
When the same setting is made within 0.5 or the output increase setting time s <0.5 seconds, the output P of the electric blower F is moved to a plurality of different stages, that is, the drive state is set by jumping over. By controlling the electric blower F to a predetermined driving state, the target output of the electric blower F can be quickly set with one setting button, the cleaning workability can be improved, and the parts can be improved. The points decrease,
The manufacturability can be improved and the manufacturing cost can be reduced.

It should be noted that the explanation was made by setting 0.5 seconds as the predetermined time. However, if the same threshold value is detected within 0.2 seconds, for example, it is judged as chattering (noise) and the current electric drive is performed. It is also possible to add setting to maintain the drive state of the blower F.

Next, still another embodiment will be described.

In the embodiment shown in FIGS. 1 to 8, as shown in FIG. 3, a stop button 12, an output reduction button 13 and an output increase button 14 are provided on the operating means as an operating portion.
Further, although the button 16 for the power brush B is provided and described, as shown in FIG. 11, only the button 71 for input setting and the button 16 for the power brush B are provided as the operation unit.

Further, as shown in FIG. 12, a two-wire transmission line
Operation means connected to the control means 25 via 51, 52
In the 26, a current limiting resistor 56 that detects the connection of the hose 2 is connected in series between the two-wire transmission lines 51 and 52, and is operated in parallel with the resistor 56 by an input setting button 71. A series circuit of a normally open switch 72 and a resistor 73, and a series circuit of a normally open switch 63 and a resistor 64 operated by the button 16 for the power brush B are connected. In addition, resistance 7
The resistance values of 3 and 64 are set to different resistance values.

Then, as shown in the flow chart of FIG. 13, the input setting time u = 0, indicating that the input is not recognized a =
The value is set to 0 (step 101), the current is read by the current detecting means 34 (step 102), and the presence or absence of connection of the hose 2 is detected by the threshold value of the current (step 103). 2 depending on the current threshold
When it is detected that the line transmission lines 51, 52 are open, it is determined that the hose 2 is disconnected, and the electric blower F is stopped after 1 second (step 104), and it is not recognized a = 0. Is set (step 105) and the process returns to step 102.

When it is judged that the hose 2 is connected, it is detected whether or not there is an input pulse of the input setting button 71 (step 106), that is, the input setting is made by the current threshold value. When it is determined that the button 71 of is operated, the input processing for controlling the electric blower F is performed (step 107), and the process returns to step 102.

If it is determined in step 106 that the input setting button 71 is not operated due to the threshold value, it is detected whether or not there is an input pulse of the power brush B button 16 (step 108). When it is determined that the button 16 for the power brush B has been operated, the power brush B
Is operated (step 109) and the process returns to step 102. Incidentally. When the button 16 for the power brush B is operated and the electric blower F is not driven, the electric blower F is also driven in the automatic state.

If it is determined in step 108 that the button 16 for the power brush B is not operated by the threshold value, it is determined that the threshold value is the end threshold value, and the process returns to step 102 to cycle through the loop and enter the standby state. , Maintain the previous behavior.

Then, when the control of the input process is selected, the operation of the flowchart shown in FIG. 14 is performed.

First, it is judged whether or not a = 0 indicating that the recognition is not performed (step 111).
When = 0, x = 1, which means that the output of the electric blower F is increased, is set (step 112), and the output P = 4 of the electric blower F is set (step 113). Next, the input setting time u = 0 is set, the timer is timed at u = 0 (step 114), and a = 1, which is the recognition result, is set (step 115), and the process proceeds.

If it is judged in step 111 that a = 0, which means that the recognition is not performed, that is, if it is determined that a = 1, which means that the timer has already been counted at u = 0 and the recognition has been performed,
It is judged whether or not the input setting time u <0.5 seconds (step 116), and if u <0.5 seconds, that is, u
If ≧ 0.5 seconds, it is determined whether or not x = 1 to increase the output of the electric blower F (step 117). Then, when x = 1, it is determined whether or not the output P = 7 of the electric blower F (step 118).
), And if P = 7, x = 0 is set to the effect that the output of the electric blower F is reduced (step 119), and P =
P-1 is set (step 120) and the process proceeds to step 114 and thereafter. If P = 7 is not set, P = P + 1 is set (step 121) and the process proceeds to step 114 and thereafter.

If x = 1, which means that the output of the electric blower F is increased in step 117, that is, if x = 0 that means that the output of the electric blower F is decreased, then the electric blower F Of the output of the electric blower F is determined (step 122). If P = 1, the output of the electric blower F is set to x = 1 (step 123), and P = P + 1 is set (step 121), and the process proceeds to step 114 and subsequent steps. If P = 1 is not satisfied, P = P
-1 is set (step 120) and the process proceeds to step 114 and thereafter.

Then, in step 116, the input setting time u
If it is <0.5 seconds, control for stopping the electric blower F and the power brush B is performed (step 124),
In step 115, a = 1, which is the recognition result, is set, and the process proceeds.

Next, another embodiment will be described.

In the embodiment shown in FIGS. 11 to 14, it has been explained that the control for stopping the electric blower F and the power brush B is performed when the same setting is performed within a predetermined time. As shown in FIG. 15, a description will be given of a case where the setting of the predetermined time is changed and another control is performed.

That is, when the control of the input process is selected, as shown in FIG. 15, first, it is not recognized.
= 0 is determined (step 131), and if a = 0, which indicates that the recognition is not to be performed, x = 1 is set to increase the output of the electric blower F (step 132). The output P of the blower F is set to P = 4 (step 133). Next, the input setting time u is set to 0, the timer is timed at u = 0 (step 134), and a = 1, which indicates the recognition, is set (step 135), and the process proceeds.

If it is determined in step 131 that a = 0, which means that the recognition is not performed, that is, if it is determined that a = 1, which means that the timer has already been counted at u = 0 and the recognition is performed,
It is judged whether or not the input setting time u <0.5 seconds (step 136), and if u <0.5 seconds, that is, u
If ≧ 0.5 seconds, it is determined whether or not x = 1 to increase the output of the electric blower F (step 137). Then, when x = 1, it is determined whether or not the output P = 7 of the electric blower F (step 138).
), And if P = 7, set x = 0 to reduce the output of the electric blower F (step 139), and P =
P-1 is set (step 140) and the process proceeds to step 134 and thereafter. If P = 7 is not set, P = P + 1 is set (step 141) and the process proceeds to step 114 and thereafter.

If x = 1, which means that the output of the electric blower F is increased in step 137, that is, if x = 0 that means that the output of the electric blower F is decreased, then the electric blower F Of the output of the electric blower F is determined (step 142). If P = 1, x = 1 is set to increase the output of the electric blower F (step 143), and P = P + 1 is set (step 141), and the process proceeds to step 114 and thereafter. If P = 1 is not satisfied, P = P
-1 is set (step 140) and the process proceeds to step 114 and thereafter.

Then, in step 136, the input setting time u
If <0.5 seconds, input setting time u <0.2
It is determined whether or not the second is reached (step 144) and u <0.2.
If it is seconds, it is judged as chattering (noise),
Set a = 1, which indicates that the recognition is made to maintain the current state (step 135), and proceed to the next step. If u <0.2 seconds, that is, 0.5> u ≧ 0.2 seconds. If it is, control is performed to stop the electric blower F and the power brush B (step 145), a = 1 is set, which is the effect recognized in step 135, and the process proceeds.

In this way, the control means 25 sets a plurality of threshold values for each state set by the various setting buttons 71, 16 of the operation means 26, controls the electric blower F according to these threshold values, and operates the operation means 26. If the same setting is performed for a predetermined time, that is, the input setting time u <0.5 or u <0.2 seconds, the stop threshold value is set, or
By controlling the electric blower F to a predetermined state such as setting to maintain the current state, it is possible to perform a plurality of controls with one setting button, which reduces the number of parts, improves manufacturability, and reduces manufacturing cost. In addition to being able to reduce the amount, it is possible to quickly perform a predetermined control and improve the cleaning workability.
