Description

Vacuum cleaner with wireless control {RADIO CONTROL VACUUM CLEANER}

The present invention relates to a vacuum cleaner that can be wirelessly controlled, and more particularly, in a general household vacuum cleaner, a user's grip part configured to hold a user's hand and adjust a cleaning direction of a floor brush necessary for cleaning. In addition to the transmitter to emit a key input signal to the outside, the suction hose connecting the body and the handle portion by a wireless wire by incorporating a receiver in the body of the vacuum cleaner that receives the emission signal and transmits a control signal to the respective internal parts The present invention relates to a vacuum cleaner with a wireless control that can be configured in a light and elastic structure of the user so that the user can easily and effortlessly clean the product.

In general, a hose used for a vacuum cleaner is configured such that the hose itself serves as an electric wire. That is, as shown in Figure 1, the hose 9 for a cleaner made of a multi-extrusion molding band 10 has a feature that the wire (1) is embedded therein.

Accordingly, the two or three strands of wire are wound around the inner wall of the hose in a spiral at a predetermined interval so that the wire maintains and reinforces the shape of the hose, and at the same time, the current flows through the wire to form a control key. The control signal of the handle portion is to be transmitted to the main body.

However, various control keys for turning on / off the power and adjusting the strength of the suction power of the main body are provided in the handle of the vacuum cleaner, and when the hose is connected to the hose connector of the handle, a connection between the wire of the hose and the switch of the handle is made. The handle inserted into the hose by direct connection is integrated with these hoses without any rotational force. The hose is twisted gradually while the user moves the cleaner around, and the handle is re-fixed according to the twisted state. In addition, the user has a problem that the user feels a lot of inconvenience in the use by the characteristic of having a heavy and stiff feeling by the insertion of the wire as well.

In particular, the above-mentioned problems have been highlighted even more because women are mainly responsible for the use of such a cleaner, that is, house cleaning.

In order to overcome this problem, as shown in FIG. 2, an infrared light emitting unit 2 is configured in a handle portion of a vacuum cleaner, and an infrared light receiving unit 4 receiving infrared light transmitted from the infrared light emitting unit is provided in the main body. Infrared type wireless cleaners are used to configure and transmit the control signal of the handle part to the main body in a wireless manner.

However, such a conventional infrared wireless vacuum cleaner has a light emitted from the infrared light emitting portion of the handle portion should be reflected to the ceiling or the wall to reach the infrared light receiving portion of the main body, the output of the light output from the infrared light emitting portion by the angle of the handle portion The angle is changed or the reflection angle is changed due to an obstacle on the reflection path of the light so that the light output from the infrared light emitting unit does not reach the infrared light receiving unit properly, thereby preventing stable wireless control.

The present invention has been made to solve the above problems, the receiving unit for externally emitting the user input signal of the operation panel to a predetermined output to the handle portion provided with the operation panel of the vacuum cleaner to a predetermined output and receiving the emitted user input signal Is built into the main body connected to the handle part and the suction hose to perform the function control of the main body so that the suction hose between the main body and the handle part can be replaced with a flexible wireless hose, so that the user's cleaning operation can be done easily and conveniently. It is to provide a vacuum cleaner that can be controlled.
