Description

  The present invention relates to a method for controlling an electric vacuum cleaner used for cleaning a futon in general household cleaning.

  Mite allergens due to ticks lurking in bedding are attracting attention among patients with allergic constitutions that have increased in recent years. There are several ways to remove the mites, such as sun-drying and tapping, but it is most effective to remove the mites and their feces in the futon by vacuuming the bedding.

This type of conventional vacuum cleaner has a reversal timing of the forward and backward of the suction tool in the futon cleaning operation mode so that the tick can be surely sucked out by cleaning the futon that was cleaned by the user's sense. In some cases, an instruction sound for instructing is pronounced and notified at regular intervals (see, for example, Patent Document 1).
JP-A-2-121616

  However, in the conventional vacuum cleaner, when the power supply to the electric blower is increased in order to further remove the ticks, the futon is covered and it is difficult for the user to avoid the state. If this state is repeated, the electric blower may be overheated. On the other hand, the user is forced to change the mode to a mode with a weak suction force by the changeover switch, but the suction force is weak, so it takes a lot of time for cleaning, and there is a problem that it is inconvenient for the user. It was.

  The present invention solves the above-mentioned conventional problems, reduces the stickiness when cleaning floors and futons, improves user convenience so that cleaning can be performed in a short time, and It aims at providing the vacuum cleaner which can suppress overheating of an air blower.

  In order to solve the above-described conventional problems, an electric vacuum cleaner according to the present invention includes an electric blower that sucks dust-containing air, a drive unit that drives the electric blower, and a control unit that controls power supply to the electric blower. An operation switch for starting operation, a futon mode switching means for switching between the futon cleaning operation mode and the normal cleaning operation mode, and a futon mode input storing a plurality of power supply amounts to the electric blower in the futon cleaning operation mode And a pattern storage means, wherein the amount of power supplied to the electric blower is gradually reduced based on the plurality of stored power supply amounts during the futon cleaning operation mode. .

  Thereby, during the futon cleaning operation mode, the electric blower can be operated so that the amount of electric power supplied to the electric blower is reduced stepwise so that the floor surface and the futon do not stick.

  The electric vacuum cleaner of the present invention can reduce the sticking between the nozzle and the surface to be cleaned when cleaning the floor surface or futon, and can improve the convenience of the user.

  According to a first aspect of the present invention, there is provided an electric blower for sucking dust-containing air, a drive means for driving the electric blower, a control means for controlling power supply to the electric blower, an operation switch for starting operation, and a futon cleaning Futon mode switching means for switching between an operation mode and a normal cleaning operation mode, and a futon mode input pattern storage means for storing a plurality of power supply amounts to the electric blower in the futon cleaning operation mode, the futon cleaning operation mode During the operation, the power supply amount to the electric blower is decreased stepwise based on the plurality of stored power supply amounts, and the power supply amount to the electric blower is reduced stepwise. By doing so, the sticking between the nozzle and the surface to be cleaned when cleaning futons can be reduced, and cleaning can be performed in a short time.

  In addition to the first invention, the second invention is provided with an operation state detection means for detecting the operation state of the electric blower, and the control means calculates through the operation state detection means during the futon cleaning operation mode. When the suction air volume of the electric blower is close to zero, the amount of power supplied to the electric blower is reduced by one step. When it occurs temporarily, the suction force of the electric blower is lowered by one step. Therefore, when the futon or the like is subsequently cleaned, it is difficult for the nozzle and the futon to stick.

  The third invention is characterized in that when the operation switch is pressed during the futon cleaning operation mode of the first or second invention, the power supply amount to the electric blower returns to the initial value. When the operation switch is pressed during the futon cleaning operation mode, the suction power can be restored again by returning to the initial power supply amount if the user's intention is not met.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a perspective overview of the electric vacuum cleaner according to Embodiment 1 of the present invention.

  In FIG. 1, an electric blower 2 is housed in a cleaner main body 1 (hereinafter referred to as a main body) to generate a suction force. A hose 3 is connected to the main body 1, and an operation unit 4 operated by a user is provided at a part of the hose 3. Further, a suction port body 6 is connected from the hose 3 through the extension pipe 5.

  The main body 1 has a dust collection chamber 7 in which a dust collection bag is accommodated. Reference numeral 9 denotes a control unit having control means described later.

  FIG. 2 is a block diagram showing a first control example of the electric vacuum cleaner according to the present embodiment, FIG. 3 is a flowchart for explaining the operation, and FIG. 4 is a characteristic diagram for supplementing the explanation of the operation.

  In FIG. 2, when the operation switch 11 is turned on, the control unit 12 outputs a signal to the driving unit 13, and the driving unit 13 controls the power supply of the electric blower 2 in response to this. Further, the operation state detection means 14 detects the operation state of the electric blower 2, and in response to this, the control means 12 calculates the suction air volume of the cleaner. As the operating state detection means 14, there are means for detecting the current of the electric blower 2, an air protector for detecting the pressure in the air passage, and the like. The input pattern storage means 15 stores a plurality of input control patterns of the electric blower 2 (“input A”, “input B”, “input C”, etc. described later).

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user turns on the operation switch 11 (step 1), the control means 12 sends a signal to the drive means 13 to control power supply to the electric blower 2 and start operation. At this time, since it is necessary to suck dust and mites in the futon that are difficult to suck in normal operation, operation is performed at “input A” (for example, 600 W) that is higher than “standard” (for example, 300 W) (step 2). ).

  Here, in particular, if the cleaning can be continued without sticking futon or sheets, the operation is continued at “input A” without any problem. However, if it is difficult to clean a user with a futon cover, it is necessary to adjust the input. In other words, when the “input A” is in operation, the futon is covered with a flash and the input is down (step 3). After that, the user removes the futon from the cover and the air volume is reduced. The operation for returning is performed with “input B” (for example, 500 W) lower than the previous “input A” (step 4).

  In addition, when “input B” is applied, the futon is clogged during operation and the input is down due to instantaneous clogging (step 5). Operation is performed at a lower “input C” (for example, 400 W) (step 6). Finally, when the operation switch 11 is turned off, the electric blower 2 stops (step 7).

  In this example, a futon or a sheet with a burr is given as an example, but the present invention can also be applied when cleaning a floor surface such as a curtain or a carpet.

  In the above embodiment, the input control pattern has three stages of “input A”, “input B”, and “input C”, but the number of stages may be increased or decreased regardless of this.

  As described above, according to the present embodiment, it is possible to improve user convenience by lowering the input step by step to reduce sticking of the floor surface or futon and performing cleaning in a short time. In addition, overheating of the electric blower 2 can be suppressed.

  FIG. 5 is a block diagram showing a second control example of the electric vacuum cleaner in the present embodiment, FIG. 6 is a flowchart for explaining the operation, and FIGS. 7 and 8 are characteristic diagrams for supplementing the explanation of the operation.

  In FIG. 5, reference numeral 16 denotes a futon mode switching means for switching between the futon cleaning operation mode and the normal cleaning operation mode. When the user switches to the futon cleaning operation mode, a signal is output to the control means 12. The futon mode input pattern storage means 17 stores a plurality of input control patterns of the electric blower 2 in the futon cleaning operation mode.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the user attempts to clean the futon, the futon mode switching means 16 determines whether or not the futon cleaning operation mode has been switched (step 21 in FIG. 6). When switching to the futon cleaning operation mode, the futon mode switching means 16 outputs a signal to the control means 12 (step 22). Next, when the user turns on the operation switch 11 (step 1), the control means 12 sends a signal to the drive means 13 to control the power supply to the electric blower 2 and the operation starts. At this time, since it is necessary to suck dust and mites in the futon that are difficult to suck in normal operation, operation is performed at “input A” (for example, 600 W) that is higher than “standard” (for example, 300 W) (step 2). ).

  Here, when the operation is performed at “Input A”, the futon is covered with a cover and instantaneously becomes clogged, and the input goes down (step 3). Then, the user removes the cover from the cover and the air volume The operation is performed with “input B” (for example, 500 W) lower than the previous “input A” (step 4).

  In addition, when “input B” is applied, the futon is clogged during operation and the input is down due to instantaneous clogging (step 5). Operation is performed at a lower “input C” (for example, 400 W) (step 6). Finally, when the operation switch 11 is turned off, the electric blower 2 stops (step 7).

  Here, the input of such a futon cleaning operation mode cannot be uniquely determined because the conditions that the futon or the sheet sticks to are due to many factors such as the type and state of the futon and the user's operating force. This is because it is necessary to make the input conditions according to each factor.

  As described above, according to this embodiment, in the futon cleaning operation mode, the input is lowered step by step to reduce sticking of the futon, and cleaning is performed in a short time, thereby improving user convenience. In addition, overheating of the electric blower 2 can be suppressed.

  Further, when the operation switch 11 is pressed again during operation in the “input B” and “input C” in the futon cleaning operation mode, it is possible to return to the initial input “input A”. This is a consideration when the user has become accustomed to the operation of the futon cleaning and wants to increase the suction force, and improves the usability of the user.

  Further, in FIG. 8, for example, during operation at “input B” in step 4, the input is gradually increased (for example, 10 W) step by step at regular intervals (for example, 10 W), the suction power is increased, and the dust and mites are removed. By improving the user-friendliness, the user-friendliness can be improved.

  FIG. 9 is a block diagram illustrating a third control example. In FIG. 9, by providing a memory 18 that stores specific input conditions in the futon cleaning operation mode in which a plurality of inputs are switched to perform the cleaning operation, for example, to clean the futon in the futon cleaning operation mode and finish the cleaning. The operation switch 11 is turned off and the immediately preceding input condition is stored in the memory 18. When cleaning again in the futon cleaning operation mode, the power supply of the electric blower 2 is controlled using the input conditions stored in the memory 18 as initial conditions.

  Accordingly, since the use conditions adapted to the individual usage of the user can be stored in the memory 18, the user-friendliness can be improved.

  FIG. 10 is a block diagram illustrating a fourth control example.

  In FIG. 10, by providing the change means 19 that can change the contents of the input control pattern stored in the futon mode input pattern storage means 17, for example, even after the control unit 9 is once incorporated in the main body 1. Since the condition data of the input control pattern can be changed, it is possible to cope with a sudden specification change, and it is also possible to easily change the condition data in a market repair service. As a specific example of the changing means 19, a communication circuit that performs serial communication with the outside of the main body 1 or a switching resistor circuit provided in the circuit of the control unit 9 may be used.

  FIG. 11 is a block diagram showing a fifth control example, and FIG. 12 is a schematic diagram of the display means 20 of the control example.

  The display means 20 is composed of, for example, a plurality of LEDs and a liquid crystal display. In the futon cleaning operation mode, it is possible to improve the convenience of the user by displaying the input state during operation.

  FIG. 13 is a block diagram illustrating a sixth control example.

  The voice output means 21 guides the driving state. For example, the operation mode of “futon cleaning operation mode” and “normal cleaning operation mode” and the input control level in the futon cleaning operation mode are guided by voice. Therefore, the user convenience can be improved by receiving the voice guidance.

  As described above, the electric vacuum cleaner according to the present invention can improve the user-friendliness when cleaning floors and futons, so that it is not only used at home, but is also an accommodation facility such as a hotel or an inn. Or, it can be applied for business use in facilities such as hospitals and nursing homes.
