The conventional vacuum cleaner is constructed as described above, and the operation information obtained by operating the operation button 9a is as follows.
The light is emitted from the infrared light emitting element 8a and is received (received) by the infrared light receiving unit 7. On the main body 1 side, the blower motor is driven based on the received signal. Further, light is emitted from the infrared light emitting element 8b toward the ceiling, and the reflected light is received by the light receiving section 7, thus forming a double system.

[0005]

In the conventional vacuum cleaner as described above, if the upper part of the light emitting element 8a is covered with the hand during cleaning, the operation information cannot be transmitted. At this time, the light emitted from the other light emitting element 8b may be reflected by the ceiling or the like and incident on the infrared light receiving portion 7. However, if a place where there is no object that reflects infrared rays happens to be cleaned, such as the ceiling, the operation information Is not reliably transmitted to the main body 1 and the reliability of the transmission of operation information is low. Further, since the light emitting elements 8a and 8b are arranged at two places as shown in FIG. 5, there are problems that the wiring becomes long and that the assembly work is troublesome and the cost is high.

The present invention has been made to solve the above problems, and an infrared light emitting portion is provided at the bottom of the hose, and the directions of light emitted from two light emitting elements arranged back to back are mutually different. An object of the present invention is to obtain an electric vacuum cleaner in which the light is received in the opposite direction without being shielded in all directions and the reliability of transmission of operation information is improved.

[0007]

An electric vacuum cleaner according to the present invention is provided with a transmitter for wirelessly transmitting operation information of an operating unit at the hand of a hose, and a transmitter provided for a main body of the cleaner. And a receiving device for receiving the received signal,
In an electric vacuum cleaner that drives a blower motor based on the signal received by the receiving device, the transmitting device is installed back to back at the bottom of the hose proximal part, and when the bending angle of the hose proximal part is θ, it is mounted forward. The signal emitting angle θ ₁ of the transmitting element is set to 0 ° to θ °, and the signal emitting angle θ ₂ of the transmitting element mounted at the rear is θ ° to 90 °.
It is composed of two transmitting elements set to.

[0008]

Is set to 0 ° to θ °, and the signal emission angle θ ₂ of the transmitting element mounted on the rear side is set to θ ° to 90 °, so that the signal from the light emitting element is blocked in all states during cleaning. Arrives at the receiving device without being disturbed.

1 is an external view of an electric vacuum cleaner according to an embodiment of the present invention, FIG. 2 is a sectional view showing a hose proximal portion of the electric vacuum cleaner shown in FIG. 1, and FIG. 3 is an embodiment of the present invention. It is an explanatory view explaining how to attach a light emitting element. 1 to 3, parts designated by the same reference numerals as those in FIGS. 4 to 6 are the same parts, 15 is an infrared light emitting portion, and 15a is an infrared light emitting element housing portion, which is made of a material that transmits infrared rays. 15
Reference numerals b and 15c are infrared ray emitting elements, and 15d and 15e are infrared ray emitting element terminals. The infrared light emitting portion 15 is installed at the bottom of the hose proximal portion 4 and in a portion near the connection portion with the connection pipe 5. Here, the "bottom portion" is a portion that is on the lower side in a state where it is normally cleaned (the state of FIG. 1), and this portion will be referred to as the bottom portion of the hose hand portion 4.

FIG. 3A illustrates the bending angle θ of the hand portion 4 of the hose. Hose grip portion 4, the upper case 4a, the lower case 4b, consists grip 4c, the lower case 4b has a connection pipe side cylindrical portion and the hose-side cylindrical portion, and the connecting pipe side cylindrical portion central axis l ₁ It intersects with the central axis l _{2 of the} hose side cylindrical portion at an angle of θ. This angle θ will be referred to as a bending angle of the hose proximal portion 4.
3B is a side view showing the mounting angles of the infrared light emitting elements 15b and 15c, and FIG. 3C is a front view of FIG. The control board 11c is parallel to l ₁ and the lower case 4 of the hose proximal portion 4
It is fixed to the lower surface of the cylindrical portion of the connection pipe side of b. That is,
It is fixed to the bottom of the hose proximal portion 4 at a portion near the connection portion with the connection pipe 5. The infrared light emitting element 15b is fixed so that its terminal 15d forms an angle of θ _{1 with} the control board 11c. Further, the infrared light emitting element 15c is fixed so that its terminal 15e forms an angle of θ ₂ with respect to the control board 11c. Therefore, the direction of the light emitted from the infrared light emitting element 15b mounted on the front side, that is, on the side closer to the connection pipe 5, is the direction forming an angle θ ₁ with respect to the control substrate 11c, that is, l ₁ . . Similarly, the direction of the light emitted from the infrared light emitting element 15c attached to the rear is a direction forming an angle of θ ₂ with respect to l ₁ .

Θ ₁ is set to 0 ° to θ °. This is set to 0 ° to θ ° because the structure cannot be 0 ° or less, and if θ ° or more, the role sharing with the light emitting element 15c becomes unclear. Further, θ ₂ is set to θ ° to 90 °. This is because if the angle is set to θ ° or less, the infrared rays do not reach the main body 1 due to the hose connection portion becoming obstructive, and if the angle is set to 90 ° or more, the role sharing with the light emitting element 15b becomes unclear. And Further, as shown in FIGS. 1 and 3A, when cleaning, the operation is to move the floor brush 6 back and forth with the central axis l ₂ horizontal (parallel to the floor surface). Since the force is the lightest, the user often cleans in a state close to the above. Therefore, taking this condition into consideration, θ ₁ and θ ₂ are set to the bending angle θ of the hose proximal portion 4.
By setting as described above in relation to the above, the light from the infrared light emitting unit 15 is surely prevented from being shielded.
Is transmitted to the infrared ray receiving section 7.

During cleaning in the state shown in FIG. 1, the light from the infrared light emitting element 15c is received by the infrared light receiving portion 7. When the floor brush 6 and the connecting pipe 5 are moved in the direction in which the floor brush 6 and the connection pipe 5 are reversed with the main body 1 left as it is, the light from the light emitting element 15b is received by the light receiving section 7. Further, when the floor brush 6 passes the main body and the light emitting unit 15 also passes the main body 1, the light of the light emitting element 15c is received again.

In the above embodiment, the operation information is transmitted by using infrared rays, but it may be transmitted by another medium such as radio waves.

[0014]

As described above, according to the present invention, the transmitting device is composed of two transmitting elements which are installed back to back on the bottom of the hose, and the bending angle of the hose is θ.
Then, the signal emitting angle θ ₁ of the transmitting element mounted in the front is set to 0 ° to θ °, and the signal emitting angle θ ₂ of the transmitting element mounted to the rear is set to θ ° to 90 °. Therefore, the signal from the light emitting element reaches the receiving device without being blocked in all the states during cleaning. Therefore, the reliability of the transmission of the operation information from the transmitting device to the receiving device is improved. Moreover, since the transmitters can be collectively installed in one place, the cost can be reduced.
