Steady at 2 mυ
If the DC output from sensor 1 is large compared to the voltage corresponding to the reference air volume when performing Jlfl, electric feed 1! It outputs an output signal indicating that the rotation of the electric blower 10 should be increased, and conversely, if the DC output from the sensor 1 is small, it outputs an output signal that indicates that the rotation of the electric blower 10 should be decreased. The output signal output from the comparison means 2 is input to the addition output determination means 3, and this addition output determination:

ff: It is impossible to detect only ff:, and conventionally, the standard for electric transmission J[ was set for jutans that require the maximum load, so it was difficult to detect the body surface condition with a light load such as a cushion floor. However, since the input voltage to the electric blower increases until the input voltage is equal to the maximum load (JUTAN m), the running load f of the floor brush becomes heavier due to an unnecessarily increased input.
There was also an economic problem.

In addition, a vacuum cleaner that automatically controls an electric blower according to the condition setting of the surface to be cleaned has been proposed, although this is not publicly known, and in this case, it was not possible to make intermediate settings such as other setting input values.

If the power is on, proceed to step ■. In step (2), it is determined whether the suction force range set by the on/off input setting means 2a is a curtain range. If it is a curtain range, proceed to step (3), and the reference of the sensor circuit becomes the curtain range. Furthermore, the process proceeds from step (2) to step (2), and the trigger output conversion means 42 is set to curtain. Proceed to the invasion step O. Conversely, if the suction force is not within the curtain range at step ◎, proceed to step 0. In step [phase], it is determined whether the suction force is sofa range or not, and if it is set as sofa range, the process proceeds to step ■ through step ■ and step ■ in the same way as above, and step [phase] If the suction force is not that of the sofa, proceed to step (3) and determine whether the suction force is that of the floor or the Tatami range.

Next, the operation of this embodiment will be explained with reference to FIGS. 5 to 11.

Set the cursor 3G on the grip part 24 at the tip of the hose 23 connected to the vacuum cleaner main body 21 with the n part 27, and set the cursor 3G to the condition written on the display board 37. By setting the electric transmission J! II! !

The flap 48, which is pivoted within the water body 21, is stopped at a position where it balances with the spring 50 due to wind pressure or the wind m.

The distance between the magnet 49 fixed to the flap 48 and the Hall element 46 fixed to the support base 47 becomes the sensor output. When the magnet 49 fixed to the flap 48 approaches the Hall element 46, the input to the Hall element 4G becomes large, and when the magnet 49 moves away from the Hall element 46, the input becomes small.

This 'CN and on/off input setting means 28
According to the conditions set in , the input power is increased or decreased to control the output of the electric blower 43.

In addition, the feedback of the operation is provided by Sen-45, electric blower l1143, exhaust air passage 105 in the main body 21,
It consists of 45 y-paths.

The graph of FIG. 13 regarding this operation will be explained.

FIG. 13 is a Q8 curve of the intake amount and wind pressure of the present invention, and is an example when the characteristic is set to manual full power, the characteristic ``is set to jutan, and the characteristic ■ is set to floor and tatami.

The solid line of characteristic (■) is when the filter is not clogged, and the QHIII line of characteristic Ia is lower than that of characteristic (2) when the filter is clogged. ffl with E movement fish
This is because the claw is attenuating, so to return to E and the original solid line, increase the input, and as the output increases to compensate, it will become like characteristic 1 [b, and the ability will recover, and the ability will always remain unchanged. It is possible to obtain a stable Ql (curve).

Similarly, when set to floor or tatami, when the characteristic (2) tends to become clogged, it becomes the characteristic 1a, but by correction, a curve of the characteristic llIb can be obtained. FL has enough special features to be used with light loads, such as setting floors, tatami, sofas, and curtains.
Since the margin is larger than when the setting is JLL power, the margin of the compensation valve is also large, and it can be used with good compensation.

Le revised Al-j;, 1F1■ It is rough, the characteristic work is FULL power, the characteristic ■ is G1-Tan, the characteristic ■ is floor, Tatami.

The suction limit air volume Q1 of the dust suction capacity is, for example, Q=0.
If the rate is 6 d/min and the section up to the point where each surface intersects is set to 01, the suction capacity can be used at a constant value in this section. Moreover, it is always horizontal to the G axis, and the suction capacity Q is constant. In addition, if the setting condition is that a lighter load is sufficient, for example, consider the case of floor, tatami and jutan, the setting condition of floor, tatami that requires less load, the longer the section that can be used with a constant suction force, Also, do not input more than necessary!
f. The vacuum cleaner is characterized in that the suction force is always maintained at a constant level, and the interval between the degree of vacuum (T:1) in FIG. 13 can be precisely controlled.

Although the on/off input setting means 28 has been described as being provided in the hand-operated FA 27 of the hose 23, the on/off input setting means 28 may also be provided on the cleaner body 21.

According to the above embodiment, for example, the salary deduction surface is
Turn on/o 7 input settings for various conditions such as floor, tatami, etc.F stage 2
By setting 8, the range of control by the sensor 45 signal is limited, and stable operation can be obtained through more accurate control mainly for filter clogging and dust clogging, and stable operation can be obtained from unstable sensors. The signal of (
In order to compensate for the increase in input when the duration and number of extractions of No. , stable operation is achieved.

In addition, by obtaining input power that matches the setting flexibility, it is possible to prevent input power from flowing into the t-transfer Jillj 143 more than necessary, thereby saving energy.

Furthermore, the control for reducing the input of the electric blower 1143 is as follows:
Compared to the case of an increase in input, the number of times the signal is extracted from the sensor is increased, and the input is decreased in the same steps as the increase, resulting in stable operation.

Further, the variable range of the on/off input setting means 28 is set to the lower half of the standard input setting value in the upper row and the upper half of the standard manual setting value in the lower row, that is, for example, in the on/off input setting means 28. When set to the sofa range, the upper limit of the output is the floor and the middle of the Tatami range, and the lower limit is the middle of the curtain range.The fine adjustment range is set to the floor, the lower half of the Tatami range, the entire sofa range, and the curtain range. It can also be the top half of the microwave.

By setting in this manner, it is convenient to limit the range of fine J notes, so that the range of fine J marks does not become unnecessarily wide.

In addition, as shown in FIGS. 6 and 7, the fine adjustment knob 3
A switching knob 110@ is provided near the on/off manual setting means 28, and the setting value is changed by 1iJ only when one specified Ia semi-large input of the on/off manual setting means 28 is performed. F can also be made i1-functional.

In FIGS. 6 and 7, 110 is a switching knob, and this switching knob 110 rotates a rotary switch 111 to change a variable setting value. It also has a display section 112 that displays the set value set by the rotary switch 111.

To explain the circuit diagram with reference to FIG. 8, the variable resistor 32 for fine adjustment is connected to the variable resistor 25 via the switch 31, and when the set value is set by the switch 31, the variable resistor 25 is used only for example. , which allows fine adjustment.

If it is possible to fine-tune the input only for a specific setting like this, it will not be possible to fine-tune the input using other unnecessary setting values.
Since only the set values that require fine adjustment can be arbitrarily selected and used using the switch 31, unnecessary set values are not adjusted, thereby preventing erroneous fine adjustment.Fine adjustment can be used effectively.

〔Effect of the invention〕

According to the present invention, by setting the conditions of the surface to be cleaned, appropriate power can be supplied and energy can be saved.

The input can be finely adjusted with each set value, and the optimal electric blower output can be obtained.

In addition, by setting the range in which fine adjustments can be made to less than the lower half of the input setting value in the upper row and more than 1 minute above the standard input setting value in the lower row, the adjustment range becomes unnecessarily wide. can be prevented.

Further, by allowing fine adjustment of only one specific set value, it is possible to prevent erroneous adjustment with unnecessary set values.
