First embodiment

Fig. 1 and Fig. 2 show the appearance of the electric vacuum cleaner 100 according to the first embodiment of the present invention.

As shown in FIGS. 1 and 2, the vacuum cleaner electric vacuum cleaner 100 has a cleaner body 200, a plug 310, a power cord 320, a handle 330, and a suction member 340. The connecting tube 342 and the operation input unit 350 are connected.

In the first drawing, the vacuum cleaner 100 is supported by a storage mechanism 400 that is an accessory of the vacuum cleaner 100. Fig. 2 shows a state in which the electric vacuum cleaner 100 is used for cleaning.

The storage mechanism 400 shown in Fig. 1 is disposed in the vicinity of the outlet 410. The socket 410 is connected to an external power source 420. The external power source 420 is, for example, a commercial power source.

At the time of storage, the cleaner body 200 is supported by the storage mechanism 400 as shown in Fig. 1, and the plug 310 is inserted into the socket 410 for charging.

In the case of use, generally, as shown in FIG. 2, the operator 450 grips the handle 330, and the suction member 340 contacts the cleaning object such as the floor surface, and sucks in dust.

Fig. 3 is a block diagram showing an electrical system of the electric vacuum cleaner 100 of Figs. 1 and 2; In Fig. 3, it also shows the outline of the flow of dust and air.

As shown in FIG. 3, the cleaner body 200 includes a battery housing portion 202, a charging control unit 206, an electric blower 210, a motor control unit 216, a power input unit 220, a posture detecting unit 230, an illuminance detecting unit 235, a connection detecting circuit 241, The power input side portion 245, the illumination unit 250, the illumination control unit 260, and the dust separation storage unit 344.

The electric blower 210 has a fan 212 and a fan motor 214.

The secondary battery 204 is detachably attached to the battery housing portion 202, and the secondary battery 204 is electrically connected to the charging control unit 206 while being attached to the battery housing portion 202.

The power input unit 220 supplies power input from the external power source 420 via the outlet 410, the plug 310, and the power source line 320 to the charging control unit 206.

The charging control unit 206 charges the secondary battery 204 by the electric power from the power input unit 220.

The operation input unit 350 is provided, for example, to the handle 330, and is operated by the operator 450 when the electric vacuum cleaner 100 is used for cleaning.

The motor control unit 216 controls the start, stop, and rotation speed of the fan motor 214 in response to the operation input of the operation input unit 350. The motor control unit 216 drives the fan motor 214 by using electric power from the secondary battery 204 and using electric power from the secondary battery 204.

When the fan motor 214 rotates, the fan 212 rotates, whereby a negative pressure is formed inside the suction member 340 and the connecting pipe 342, and the dust-containing air is sucked by the suction member 340 as indicated by a broken line in Fig. 3, and then connected. The tube 342 is sent to the dust separation storage unit 344, and the dust is stored in the dust separation storage unit 344. The air that has passed through the dust separation storage unit 344 is discharged to the outside of the cleaner body 200.

When the vacuum cleaner 100 is not used for cleaning, it is preferable to store the cleaner body 200 in an upright state. This is to reduce the floor space required for storage. Moreover, it is preferable to charge the secondary battery 204 in storage.

Therefore, for example, as shown in Fig. 1, the vacuum cleaner 100 is supported by the storage mechanism 400 in an upright posture to the floor surface, and is stored in this state. Moreover, the plug 310 is inserted into the socket 410.

When the plug 310 is inserted into the socket 410, it is from the external power source 420. The electric power is supplied to the cleaner body 200 via the plug 310 and the power supply line 320, and electric power is supplied to the secondary battery 204 via the electric power input unit 220 and the charging control unit 206, and the secondary battery 204 is charged. The charging control is performed by the charging control unit 206.

At the time of cleaning, the electric vacuum cleaner 100 is generally used in a state where the plug 310 has been pulled out from the outlet 410. However, while the plug 310 is still inserted into the socket 410 for cleaning, the plug 310 can still be inserted into the socket 410.

At the time of cleaning, the motor control unit 216 rotates the fan motor 214 by the electric power from the secondary battery 204 in response to the operation input from the operation input unit 350, and the fan 212 is driven by the fan motor 214, and the suction pipe 340 passes through the connecting pipe. 342. The dust such as the floor surface is sent to the dust separation storage unit 344.

As described above, the vacuum cleaner 100 is supported by the storage mechanism 400 in an upright state during storage. In the present embodiment, the storage mechanism 400 is a mechanism for erecting the vacuum cleaner 100, and is a frame for holding the vacuum cleaner 100 against the upright.

Here, it is assumed that the electric vacuum cleaner 100 has an elongated shape as a whole, and "upright" means that the handle 330 of the electric vacuum cleaner 100 is located above the suction member 340, and the longitudinal direction of the elongated vacuum cleaner 100 is in a state close to the vertical direction. The direction close to the vertical direction means that the difference from the vertical direction is, for example, within 30 degrees.

In the example shown in Fig. 1, the storage mechanism 400 is a structure that supports the electric vacuum cleaner 100. When the connection pipe 342 and the suction member 340 are attached to the cleaner body 200, the suction member 340 is brought into contact with the floor surface, and the cleaner body is attached. 200 obliquely inclined, the side of the casing 207 (the surface of the side wall portion of the casing) 208 It is in contact with and supported by the support surface 402 of the storage mechanism 400.

The posture detecting unit 230 detects the posture of the vacuum cleaner 100 and outputs the detection result to the illumination control unit 260. The posture detecting unit 230 detects the posture of the entire vacuum cleaner 100 by detecting the posture of the cleaner body 200, for example. The posture detecting unit 230 is configured by, for example, a sensor (acceleration sensor or the like) that detects a posture. As the posture, for example, the inclination in the vertical direction is detected.

The illuminance detecting unit 235 detects the illuminance around the cleaner body 200 and outputs the detection result to the illumination control unit 260. The illuminance detecting unit 235 is, for example, a sensor (illuminance sensor) that can measure the illuminance on the surface of the casing 207 of the cleaner body 200.

The connection detecting circuit 241 constitutes a part of the connection detecting unit 240. The connection detecting unit 240 detects the connection of the power input unit 220 to the external power source 420 (thus, the connection of the cleaner body 200 to the external power source 420), and outputs the detection result to the illumination control unit 260. The connection detecting unit 240 determines whether or not the plug 310 is connected to the outlet 410, for example.

The connection detecting unit 240 includes not only the connection detecting circuit 241 but also a contact sensor.

An example of such a contact sensor is shown in Fig. 4. In the illustrated example, the contact 242 is disposed on a portion of the plug 310. The contact 242 is in contact with the surface of the socket 410 when the plug 310 is inserted into the socket 410, whereby the insertion is detected. The signal indicating the detection result is transmitted to the connection detecting circuit 241 via the signal line 243, and then transmitted from the connection detecting circuit 241 to the illumination control unit 260.

The power input detecting side portion 245 detects from the external power source 420 The power supply of the power input unit 220 (with the supply of electric power from the external power source 420 to the cleaner body 200) is output to the illumination control unit 260. The power input detecting side unit 245 detects, for example, a current flowing from the power source line 320 into the power input unit 220, and includes a sensor that can determine whether or not the power is input. The above sensor is constituted, for example, by a current sensor.

The posture detecting unit 230, the illuminance detecting unit 235, the connection detecting unit 240, and the power input detecting side unit 245 operate by electric power from the secondary battery 204.

The illumination control unit 260 controls the illumination of the illumination unit 250 and the light-off according to the detection results of the posture detection unit 230, the illumination detection unit 235, the connection detection unit 240, and the power input detection side unit 245. The illumination control unit 260 lights the illumination unit 250 by the electric power from the secondary battery 204.

The illumination unit 250 is provided to illuminate the upper direction when the electric vacuum cleaner 100 is lit upright. The illuminating unit 250 is preferably disposed on the upper side of the vacuum cleaner 100 in a state where the vacuum cleaner 100 is erected, for example, on the upper side of the cleaner body 200, and is configured to illuminate the top surface in the upper direction in a wide range in this state. . This is because it is advantageous in grasping the surrounding situation when a power failure occurs in the configuration.

When the vacuum cleaner 100 is in the use state, the illumination unit 250 is maintained in the light-off state.

When the vacuum cleaner 100 is in the non-use state, the operation in the power failure monitoring mode is started. In the power failure monitoring mode, the illumination control unit 260 performs detection of occurrence of power failure and control of lighting and turning off of the illumination unit 250.

Whether or not the electric vacuum cleaner 100 is in a non-use state is determined based on, for example, the operation of the operation input unit 350. For example, at the operation input unit 350, the fan 212 is changed. After the predetermined time has elapsed, it is judged that the non-use state is started, and after the operation input unit 350 becomes the operation of the fan 212, it is judged that the non-use state is completed.

In the power failure monitoring mode, the illumination control unit 260 monitors the outputs of the posture detecting unit 230, the illuminance detecting unit 235, the connection detecting unit 240, and the power input detecting side unit 245 (indicating the detection result), and controls the lighting unit 250 based on these outputs. Light up and turn off the lights. Refer to Figure 5 for the processing required for this control.

The processing of Figure 5 is as early as the scheduled time interval.

First, in step ST11, it is determined whether or not the cleaner body 200 is connected to the external power source 420 based on the output of the connection detecting unit 240.

In the case of "connection" (YES in step ST11), the process proceeds to step ST12.

In step ST12, based on the output of the power input detecting side unit 245, it is determined whether or not electric power is supplied from the external power source 420 to the cleaner body 200.

When it is judged that "not supplied" (NO in step ST12), the process proceeds to step ST13.

In step ST13, based on the output of the illuminance detecting unit 235, it is determined whether or not the illuminance around the cleaner body 200 is equal to or greater than the threshold value.

If it is not the threshold value or more (NO in step ST13), the process proceeds to step ST14.

In step ST14, based on the output of the posture detecting unit 230, it is determined whether or not the electric vacuum cleaner 100 is in an upright state.

If it is in the upright state (YES in step ST14), the process proceeds to step ST15.

In step ST15, the illumination unit 250 is turned on. That is, if it is previously lit, the lighting state is maintained. If it is turned off before, it will shift to the lighting state.

In step ST11, NO (not connected to the power source), YES in step ST12 (power supply is supplied), and YES in step ST13 (illuminance is a threshold value If it is NO (not in the upright state) in step ST14, the process proceeds to step ST16.

In step ST16, the illumination unit 250 is turned off, that is, if the light is turned off before, the light-off state is maintained. If it is lit before, it will shift to the light-off state.

As a result of the processing shown in Fig. 5, the illumination control unit 260 performs the following control.

In other words, the illumination control unit 260 turns on the illumination unit 250 when all of the following four conditions (a) to (d) are satisfied.

(a) From the detection result of the connection detecting unit 240, it is determined that the cleaner body 200 is connected to the external power source 420.

(b) From the detection result of the power input detecting side portion 245, it is determined that the electric power is not supplied from the external power source 420 to the cleaner body 200.

(c) From the detection result of the illuminance detecting unit 235, it is determined that the illuminance around the cleaner body 200 is less than the threshold.

(d) From the detection result of the posture detecting unit 230, it is determined that the electric vacuum cleaner 100 is in an upright state.

On the other hand, when any one of the above four conditions (a), (b), (c), and (d) (at least one) is not satisfied, the illumination unit 250 is turned off.

When the power failure is satisfied in the case where the above conditions (a) and (b) are satisfied, only at that time, the illumination control unit 260 lights the illumination unit 250.

When the above condition (b) is satisfied and the above condition (a) is not satisfied, the illumination unit 250 is turned off. This is because the power is not a power failure, but the plug 310 is not inserted into the outlet 410, so there is a possibility that power is not supplied from the external power source 420.

When the above conditions (a) and (b) are satisfied and the above condition (c) is not satisfied, the illumination control unit 260 turns off the illumination unit 250. This is due to the judgment environment In the state of light (the state of receiving sunlight or the state of other illumination lighting), in this case, even if a power failure occurs, since the surroundings are bright, it is not necessary to light the illumination unit 250.

Further, when the above conditions (a), (b), and (c) are satisfied and the above condition (d) is not satisfied, the illumination control unit 260 turns off the illumination unit 250. This is because even in the event of a power outage, the illumination light from the illumination unit 250 is prevented from directly entering the human eye.

First modification

In the above embodiment, the illumination unit 250 is turned on when all of the above four conditions (a), (b), (c), and (d) are satisfied, but instead,

(A) The illumination unit 250 may be turned on as long as the conditions (a) and (b) are satisfied (even if the condition (c) or (d) is not satisfied).

(B) The illumination unit 250 may be turned on as long as the conditions (a), (b), and (c) are satisfied (even if the condition (d) is not satisfied).

(C) It is also possible to use the illumination unit 250 to light as long as the conditions (a), (b), and (d) are satisfied (even if the condition (c) is not satisfied).

Second modification

In the above embodiment, the power input detecting side portion 245 is a sensor that can detect the current flowing from the power source line 320 into the power input portion 220, and is constituted, for example, by a current sensor, which is borrowed from the secondary battery. 204 power action.

However, the present invention is not limited to such a configuration.

For example, when a current from the external power source 420 flows, a signal indicating that there is input of power is output according to the current, and when not, the source is not output. The composition of the signal.

Third modification

In the first embodiment described above, the storage mechanism 400 is provided as an accessory of the electric vacuum cleaner 100. However, an existing structure that can function as a support, for example, a wall of a room in which the electric vacuum cleaner is stored may be used as a storage mechanism. 400.

Further, the electric vacuum cleaner 100 may be configured to be self-supporting.

Fourth modification

In the first embodiment, the case where the electric vacuum cleaner is a stick type has been described. However, the present invention can also be applied to a case where the electric vacuum cleaner is portable, and can also be applied to a case where the electric vacuum cleaner is a drum type. The present invention can be further applied to an electric vacuum cleaner (robot type electric vacuum cleaner) that is self-disciplined.

Fifth modification

In the first embodiment, it is explained that the illuminating unit 250 is provided to illuminate the upper direction when the vacuum cleaner 100 is erected.

The vacuum cleaner 100 is elongated as shown in Fig. 1, and in the storage state, the upper end, that is, the position where the illumination unit 250 is disposed is located above the average human eye, and if the illumination unit 250 is placed in the upward direction, There is an advantage that the illumination light from the illumination unit 250 does not directly enter the human eye.

However, this is not essential as long as it is set to a predetermined direction other than the upward direction of illumination.

Sixth modification

In the first embodiment, the erecting means that the longitudinal direction of the elongated vacuum cleaner 100 is in a state close to the vertical direction, but the present invention It is not limited to the case where the electric vacuum cleaner 100 is elongated. In short, in the storage, the vacuum cleaner 100 may be in a state of being in a predetermined posture, that is, a state in which it is oriented in a predetermined direction.

Further, in this state, the illumination unit 250 may be configured to illuminate a predetermined direction, for example, an upward direction.

In this case, instead of the above condition (d), the following condition (d') which generalizes the condition (d) is used.

(d') From the detection result of the posture detecting unit 230, it is determined that the vacuum cleaner 100 is in a state of being oriented in a predetermined direction.

For example, in a case where the position where the illumination unit 250 is disposed is lower than that of the human eye, by illuminating the illumination unit 250 so as to be irradiated in the downward direction, it is possible to prevent the illumination light from directly entering the human eye.

Seventh modification

The present invention is also applicable to the case where the cleaner body 200 can be separated from one or more of the suction member 340, the connection tube 342, and the handle 330. In this case, the posture detecting unit 230 detects the posture of the cleaner body 200, and the lighting control unit 260 determines whether or not the cleaner body 200 is in the predetermined direction from the detection result of the posture detecting unit 230.

Further, in this case, the cleaner body 200 may not be supported by the storage mechanism 400, and may be configured to be self-supporting while maintaining a predetermined posture. For example, it is also possible to have a protruding structure that abuts against the floor surface at the bottom of the cleaner body 200 and supports the cleaner body 200 at three points.

Second embodiment

In the first embodiment described above, the storage mechanism 400 has only branches. The function of the electric vacuum cleaner 100 is supported, but as shown in Fig. 6, the storage mechanism 400 may be a charging stand or a charging stand.

In this case, the vacuum cleaner main body 200 is electrically connected to the power receiving terminals 404 and 405 of the storage mechanism 400 and the power receiving terminals 224 and 225 of the cleaner body 200 in a state supported by the storage mechanism 400. The storage mechanism 400 has a power supply line 320 and A plug 310 is inserted into the socket 410.

Further, as the connection detecting unit 240, in addition to detecting the connection between the socket 410 and the plug 310, the connector for detecting the power supply terminals 404, 405 and the power receiving terminals 224, 225 is used.

Moreover, in the case where both of them are detected to be connected, it is judged that the cleaner body 200 is connected to an external power source.

In order to detect the connection between the socket 410 and the plug 310, the contact sensor described with reference to Fig. 4 can be used in the first embodiment.

Figure 7 shows a contact sensor that can be used to detect the connection of the power supply terminals 404, 405 to the power receiving terminals 224, 225.

In the example of Fig. 7, the contact 221 is provided adjacent to the power receiving terminals 224, 225 and protruding from the side surface (the surface of the side wall portion of the casing) 208 of the casing 207 of the cleaner body 200. The contact 221 detects the electrical properties of the power receiving terminals 224 and 225 and the power supply terminals 404 and 405 by abutting against the support surface 402 of the storage mechanism 400 when the power receiving terminals 224 and 225 are pressed against the power supply terminals 404 and 405. connection. A signal indicating the detection result is transmitted to the connection detecting circuit 241 via the signal line 223.

The connection detecting circuit 241 determines the plug from the detection result transmitted via the signal line 243 and the detection result transmitted via the signal line 223. When the socket 310 is connected to the socket 410 (a1) and the power receiving terminals 224 and 225 are connected to the power supply terminals 404 and 405 (a2), it is determined that the cleaner body 200 is connected to the external power source 420.

That is, the connection detecting circuit 241 is attached to (a1) judging from the output of the contact sensor as in Fig. 4, the condition for connecting the plug 310 to the socket 410, and (a2) Judging from the output of the contact sensor of Fig. 7, the conditions under which the power receiving terminals 224, 225 are connected to the power supply terminals 404, 405

When both are satisfied, it is judged that the above condition (a) is satisfied.

The connection detecting circuit 241 determines that the above condition (a) is not satisfied if the above conditions (a1) and (a2) are not satisfied.

The determination result of the connection detecting circuit 241 is transmitted to the illumination control unit 260 as a result of the detection by the connection detecting unit 240.

The modification applicable to the first embodiment can also be applied to the second embodiment.

According to the present invention, when a power failure occurs, since the illumination unit automatically lights up, the situation can be quickly grasped. Moreover, since the illuminating unit is provided in the electric vacuum cleaner, a separate socket and another secondary battery are not required.

Further, the electric vacuum cleaner is used frequently for cleaning, and the user is often connected to the power source in advance for charging. Therefore, it is not necessary to have a special awareness of preventing power failure, and emergency lighting can be ensured.

Further, when the condition (c) described above is satisfied, when the illumination unit 250 is turned on, the lighting can be omitted when the periphery of the cleaner body 200 is bright, and power waste can be avoided.

Further, when the above condition (d) or the above-described condition (d') is satisfied, when the illumination unit 250 is turned on, it is possible to prevent the illumination light from the illumination unit 250 from directly entering the human eye.

In the above embodiment, at least a part of the illumination control unit 260, the posture detecting unit 230, the illuminance detecting unit 235, the connection detecting unit 240, and the power input detecting side unit 245 can be realized by a processing circuit. The processing circuit can also be a dedicated hardware or a CPU that executes a program stored in the memory.

When the processing circuit is a CPU, the functions of the illumination control unit 260, the posture detecting unit 230, the illuminance detecting unit 235, the connection detecting unit 240, and the power input detecting side unit 245 are a combination of software, firmware, or a combination of a soft body and a firmware. Realized. The software or firmware is described as a program and stored in the memory. The processing circuit performs the functions of the illumination control unit 260, the posture detecting unit 230, the illuminance detecting unit 235, the connection detecting unit 240, and the power input detecting unit 245 by reading and executing the program stored in the memory.
