As shown in FIGS. 1 and 2, the cleaner body 1 has a built-in electric blower 2, and includes a hose 3 having one end connected to the body 1, an extension pipe 4 connected to the other end of the hose 3, and a suction tool 5. The HR 23/43 type nickel-metal hydride battery 6 for driving the electric blower 2
I have a book. The electric blower 2 is an inverter motor. The total mass of the nickel-metal hydride battery 6 is approximately 40% of the mass of the cleaner main body 1, the input to the electric blower 2 can be controlled in a plurality of stages, the minimum power consumption of the electric blower 2 is 100 W or more, The power is 20 W or more, the degree of vacuum at the time of the maximum suction power is 3000 Pa or more,
The configuration is such that the open air volume before dust collection is 0.4 m3 / min or more and the current value is 15 A or less. Electric blower 2
The input to the controller is such that the state of the floor surface, the presence or absence of dust, or the amount of dust in a dust collection chamber (not shown) can be controlled in multiple stages by detecting a change in the rotation speed of the electric blower 2. In order to eliminate the voltage behavior due to the memory effect during charging, a charge selection switch is provided (not shown) so that the user can select to recharge after recharging once or to recharge without discharging once. When the battery voltage becomes equal to or lower than the discharge end voltage, the circuit is cut off and the electric blower 2 is stopped to inform the user of the necessity of charging.

The input in the high suction force state is set to approximately 1.5 times or more the input in the normal use state, and the suction in the high suction force state is performed. Set the power to approximately 1.2 times or more of the suction power in the normal use state. After operating for 10 seconds in the high suction power state, automatically shift to the normal use state while gradually shortening the input time. As a result, the power consumption of the control circuit (not shown) is reduced when the remaining amount of the battery 6 falls below a predetermined value. In addition, a display means 7 is provided on the surface of the main body 1 for detecting the degree of vacuum in the dust collection chamber or the current value or the rotation speed of the electric blower 2 in a high suction force state and informing the user of the amount of dust in the dust collection chamber. ing. Further, the input to the electric blower 2 rises when the suction tool 5 or the extension pipe 4 and the suction tool 5 are removed from the hose. In addition, the type of floor surface, the presence or absence of dust on the floor surface, or the amount of dust in the dust collection chamber is detected, or the amount of dust in the vacuum cleaner main body 1 is turned off, The transition method from the input of the high suction force state to the input of the normal use state is changed accordingly.

The operation of the above configuration is as follows.

The nickel-metal hydride battery 6 has the same size, lighter weight, and larger battery capacity as compared with conventional lead batteries and nickel cadmium batteries known as secondary batteries. It is possible to reduce the weight of 1 and increase the use time, or to improve the suction force even with the same mass, thereby increasing the use time. In addition, by using 24 batteries, power consumption is 80 W or more, and available time is 25 minutes or more.

Further, when the voltage of the battery 6 becomes equal to or lower than the discharge end voltage, the circuit is cut off to stop the electric blower 2 to notify the user of the necessity of charging, so that the suction force is reduced and the cleaning is hindered. The user can be notified beforehand, and the battery life is not deteriorated without overdischarging. Furthermore, since the electric blower 2 is an inverter motor, the electric blower 2 generates less heat, the battery 6 and the electric blower 2 can be arranged close to each other, and the size of the main body 1 can be further reduced.
Further, the exhaust temperature of the electric blower 2 is usually 30 ° C to 40 ° C.
Since the temperature of the battery 6 during charging or discharging is lower than the temperature of the battery 6 of 40 ° C. to 60 ° C., the temperature rise of the battery 6 can be reduced by applying exhaust gas to the battery 6, and the battery life is also increased. Further, the input to the electric blower 2 is controlled so that the input in the normal use state and the input in the high suction force state can be selected, and the input in the high suction force state is set to about 1.5 times or more of the input in the normal use state. , After a certain period of operation in the high suction force state, by automatically shifting to the normal use state,
It is possible to secure a high suction force without increasing the number of batteries 6 and at the same time minimize a reduction in usable time. The display means 7 for detecting the degree of vacuum in the dust collection chamber or the current value or the rotation speed of the electric blower 2 in a high suction force state and informing the user of the amount of dust in the dust collection chamber is provided.
Under normal operating conditions, the input, rotation speed, and degree of vacuum are low, making it difficult to capture these changes.However, by providing a high input state, changes in input, rotation speed, and vacuum can be easily captured, and the interior of the dust collection chamber can be accurately detected. The user can be notified of the amount of dust. Conventionally, when charging a vacuum cleaner, dust is not sufficiently collected due to a small suction force, for example, when cleaning a gap. However, the use of a nickel-metal hydride battery 6 and the suction tool 5 or the extension pipe 4 When the suction tool 5 is removed from the hose 3, the input to the electric blower 2 is automatically increased, so that a high suction force can be secured and dust can be sufficiently collected. In addition, the input in the high suction force state is set to approximately 1.5 times or more the input in the normal use state,
In addition, the suction power in the high suction force state is set to be approximately 1.2 times or more the suction power in the normal use state, and the number of batteries is increased to reduce the power consumption of the control circuit when the remaining battery power drops below a predetermined level. Thus, it is possible to secure a high suction force state and at the same time to minimize a reduction in usable time. Further, by keeping the input of the high suction force state constant for 10 seconds and maintaining the high suction force state for a long time, the paper bag (not shown) in the dust collection chamber can be widely opened, and the dust collection amount is improved. it can. Also, as shown in FIG. 3, by gradually shifting from the input of the high suction force state to the input of the normal use state, it is possible to eliminate the unnaturalness as a feeling of actual use by lowering the input to the normal use state at once. By gradually lowering the transition while gradually shortening the input time at that time,
The input in the high suction force state is maintained for a long time so that the feeling of actual use does not become unnatural, and a natural feeling of use is obtained, and sufficient initial dust collection performance can be maintained. Further, in the present embodiment, the input value is shifted from the input of the high suction force state to the input of the normal use state while shortening the operation time at the respective input value. If the shift is made longer, the use time can be further extended by keeping the input of the high suction force state short enough that the feeling of use does not become unnatural. Furthermore, from the input of the high suction force state to the intermediate input between the input of the high suction force state and the input of the normal use state, the input time gradually shifts while shortening the input time. If the transition is made while increasing the time, sufficient initial dust collection performance is achieved by maintaining the input in the high suction force state long enough that the feeling of use does not become unnatural, and the feeling of using the intermediate input is unnatural By keeping the distance short enough to avoid the problem, the use time can be further extended, and it can be maintained long near the input of the final normal use state to obtain a more natural feeling of use. It also detects the type of floor surface, the presence or absence of dust on the floor surface, or the amount of dust in the dust collection chamber, and changes the transition method from the input of the high suction force state to the input of the normal use state to collect dust. By maintaining as high a suction force as possible on carpets that are difficult to carry or where there is a lot of dust,
It is possible to efficiently collect dust while minimizing the shortening of the usable time. Further, the higher the amount of dust in the dust collection chamber, the shorter the high suction force state, thereby preventing an excessive rise in temperature of the electric blower 2. In addition, the method of transition from the input of the high suction force state to the input of the normal use state is changed according to the time during which the power of the vacuum cleaner body 1 has been turned off. The input immediately before the power is turned off can be reproduced without returning to the high suction force state, and the use time can be further extended. If a certain time has passed since the power was turned off, it is determined that the cleaning place has been changed, and the input is returned to the high suction force state, so that the initial dust collection performance can be improved. Also, changing the transition method from the input of the high suction force state to the input of the normal use state according to the remaining battery level,
When the battery level is low, the operating time can be extended by shortening the high suction force state. In addition, when the remaining battery level is large, the high suction force state can be maintained for a long time, and the initial dust collection performance can be improved. As a result, even if the suction force is improved and the usage time is prolonged, the mass of the main body 1 does not increase and the main body 1 can be reduced in size, so that the portability and storage properties are improved, and electric cleaning adapted to the life cycle of the user is achieved. Machine can be provided.
