Abstract

PURPOSE:To realize a more accurate behavior control operation in accordance with the operation of a suction port and the cleaning surface by judging whether a suction port is operated or not with a pressure sensor in a cleaner main body, and also, judging whether a power brush is present or not by detecting the current of a power brush motor. CONSTITUTION:When the vacuum cleaner is in an operating state, pressure in the vacuum cleaner main body detected by a pressure sensor circuit 8 is monitored, and in the case a pressure fluctuation in a prescribed sampling time exceeds a certain value, it is discriminated that a user is operating a suction port, and the cleaner starts an automatic control operation. In this case, by the current detection sensor of a rotary brush driving motor, whether the suction port is what is called a power brush incorporating a rotary brush, or other suction port is connected can be discriminated, and in each case, the control processing can be classified into an optimal automatic control operation. Also, when the suction is in a static state, or is floating in the air, the cleaner is set to a holding operation state by reducing the suction force of the cleaner, and decreasing the speed of revolution of the rotary brush of the suction port.

As for conventional technology, as described in Japanese Patent Laid-Open No. 63-65835, a method is disclosed in which the suction force of a vacuum cleaner is sensed by a sensor and automatic control operation is performed to improve operability and save power. . However, what the sensor detects is the pressure (degree of vacuum) and air volume inside the vacuum cleaner body, and it is difficult to accurately judge the condition of the cleaning surface based only on this. In addition, even in automatic control operation, the shape of the suction characteristic diagram shown by pressure (degree of vacuum) and air volume is devised, and operation is performed according to the determined pressure-air volume characteristic. Optimal control according to the type of mouth and the usage status of the vacuum cleaner has not yet been achieved.

This monitors the pressure inside the vacuum cleaner body detected by the pressure sensor circuit 8 shown in Figure 2, and if the pressure fluctuation within a certain sampling time exceeds a certain value, the user operates the suction port. It is determined that the That is, when the user operates the vacuum cleaner and moves the suction port over the cleaning surface,
The pressure inside the vacuum cleaner body fluctuates due to changes in the pressing force against the cleaning surface due to the reciprocating operation of the suction port. On the other hand, even when the vacuum cleaner main body is operated, if the suction port is suspended in the air or is stationary on the surface to be cleaned, the pressure fluctuations described above do not occur. Therefore, constantly monitor the pressure inside this vacuum cleaner,
By calculating the fluctuation, it can be determined whether the suction port is being operated. As a result, when the suction port is in the operating state, the suction power of the vacuum cleaner is increased, and at the same time, the rotation speed of the rotating brush of the suction port is also increased. In addition, when the suction port is stationary or floating in the air, the suction power of the vacuum cleaner is lowered, and the rotation speed of the rotating brush of the suction port is also lowered to enter a standby operation state to save power and reduce noise. During standby operation, it is also possible to stop the rotation of the rotating brush at the suction port.

As described above, it is possible to determine whether the suction port is in use or not based on pressure fluctuations within the vacuum cleaner body, and to divide the operating state of the vacuum cleaner into standby operation and normal operation.

If the suction port is stationary on the cleaning surface and the vacuum cleaner is in standby mode because there is no pressure fluctuation, if you lift the suction port from the floor, the aforementioned pressure fluctuation will occur and the vacuum cleaner will The power will be increased to normal operation. In the case described above, it is not desirable to power up from the standby state to normal operation, and it is preferable for use to continue standby operation.

Therefore, as a condition for the pressure fluctuation inside the vacuum cleaner body when powering up from standby operation to normal operation, it is possible to switch from standby to normal operation only when there is a change in pressure in the direction of decrease (increase in vacuum). All you have to do is power up. In other words, when the suction port is lifted from a state in which it is in contact with the cleaning surface, the pressure inside the vacuum cleaner body increases (the degree of vacuum decreases), and the pressure in this increasing direction is Ignoring it and using the variation only in the decreasing direction of pressure,
By the method of determining whether or not the suction port is operated,
Control with better usability can be achieved.

Next, after making the above judgment, when transitioning to normal operation, the process branches depending on whether the key manual instruction from the hose is "auto" operation or "manual" operation, as shown in the flowchart. In the case of "manual" operation, the vacuum cleaner main body motor is operated strongly. On the other hand, when branching to automatic operation, the power brush presence/absence determination process 10 determines whether the suction port connected to the vacuum cleaner has a built-in rotating brush by an electric motor (hereinafter referred to as a power brush) or a suction port that does not. Do this.

In the power brush presence/absence determination process 10, a bidirectional thyristor included in a power brush drive circuit 11 that controls the phase of the power brush is fired, and a current flowing through the current line of the power brush is detected by a current transformer 12. When the power brush is connected, a current flows and the current transformer 12 detects the current and generates an output voltage, but when a suction port other than the power brush is connected to the vacuum cleaner, the current does not flow. , there is no current transformer output. This makes it possible to determine the presence or absence of a power brush. Further, the power brush presence/absence determination process is valid only when the power brush switch is ON using the switch near the hose, and this process is not executed when the power brush switch is commanded to be OFF.

前記パワーブラシ有無判断処理を経て、オート運転の処

After the power brush presence/absence determination process, the automatic operation process branches into the following two steps.

The first is automatic operation 13 when using the power brush. When using a power brush, the load on the rotating brush changes when the power brush is pushed and pulled when the power brush is reciprocated on the cleaning surface, and the load on the rotating brush changes due to changes in the pressing force of the power brush on the cleaning surface. The fluctuations cause the current in the motor that drives the rotating brushes to fluctuate. In particular, attention is paid to the fact that the range of variation in this load current varies depending on the surface to be cleaned, such as a flat floor, a folded floor, a carpet, etc., and based on this, the main body motor of the vacuum cleaner and the rotary brush drive motor are controlled.

即ち、平らな床上を掃除している時は前記回転ブラシの

In the case of a flat floor, dirt on the floor can be easily sucked in with a small suction air volume. do. On the other hand, when cleaning the carpet,
The resistance applied to the rotating brush also increases, the load current of the rotating brush drive motor also increases, and its fluctuation range is also large. When cleaning a carpet, you need to suck up dirt entangled in the carpet or dirt that is deep inside the carpet.In such cases, increase the rotation speed of the vacuum cleaner's motor to increase suction power, and also Increase the rotation speed to effectively scrape out dirt from the carpet.

Next, the second is automatic operation 14 when a suction port other than the power brush is used. In this case, the range of pressure fluctuation within the vacuum cleaner body is calculated, and the vacuum cleaner body motor is controlled based on this. As a control method, when the pressure fluctuation width is small, the rotation speed of the vacuum cleaner main body motor is low, and when the pressure fluctuation width is large, the rotation speed of the vacuum cleaner main body motor is increased. With this control, when cleaning the floor with the floor suction port, the pressure fluctuation range is small and the vacuum cleaner suction force is also small, and when the suction port with a narrow tip is used, the pressure The fluctuation range becomes larger, and control to increase the suction power of the vacuum cleaner can be realized.
