Thus, the device includes examples of how a person skilled in the art can make and use the claimed invention. It is described here to meet the requirements for implementation and best mode without imposing restrictions that are not listed in the claims.

The device 1 is a cleaning device used to clean surfaces, for example a carpeted floor 6. The device 1 comprises a housing 10 and various cleaning devices and knot assemblies that can be removably attached to the housing 10. The cleaning devices include a suction nozzle 12, an electric nozzle assembly 14, an auxiliary sleeve 16, and a nozzle 18 for cleaning with detergent. The handle assemblies comprise a vertical handle assembly 20 and a portable handle assembly 22. Any of the devices 12, 14, 16 and 18 can be installed on the housing 10 with any of the nodes 20 and 22 of the handle.

Housing

As shown in FIG. 2, the housing 10 comprises a housing 30 comprising upper and lower compartments 32 and 34 that are connected to each other. The casing 30 has a front surface 40 with upper and lower inlet openings 46 and 48. Two front wheels 50 and two rear wheels 52 are rotatably connected to the casing 30 to move the casing 10 along the floor 6 in such a position that the lower surface 54 of the casing 30 facing the floor 6. The housing 10 has two protruding pins 60 and a latch 64 with a support pointed protrusion with a start button 66 for fixing cleaning devices to the housing 10. It also has four electrical contacts 71, 72, 73 and 74, respectively, indicating ground, 5V P DC output, 24V DC output and registration of resistance. The mounting sensor 76 on the housing 30, in this example a push button switch, detects if the upper inlet 46 is closed by a cleaning device.

As shown in FIG. 3, a fan 80 with an inlet 82 and an outlet 84 is driven by an electric motor 88. The electric motor 88 also drives a drive pulley 90 through a drive kinematic chain that includes shafts 93, belts 94, pulleys 95, a bevel gear a wheel 96 and an electric drive clutch 98. A drive motor 99 rotates the rear wheels 52 to move the housing 10.

The bracket 100 for pivoting the handle is rotatably attached to the housing 30 using two pins 102. The bracket 100 has a flat top surface 104 with an outlet 105. The hole 105 is connected to the outlet of the fan 84 using a flexible tube 106. The electronic position sensor 120, in In this case, the button switch registers whether the bracket 100 and thus the vertical handle assembly 20 are in a vertical or inclined position. A multi-pin electrical terminal 124 of the housing is located on the upper surface 104 of the bracket.

The circuit of the control device 130 is electrically connected to the electric elements 71-74, 76, 88, 98, 99, 120 and 124 (FIGS. 2 and 3) of the housing 10 for monitoring and controlling the operation of the vacuum cleaner. The circuit 130 is powered from the network via a power cord 132. It generates power with voltages of 5V DC at the output and 24V DC at the output, which are supplied through the output contacts 72 and 73, rated for 5V DC and 24V DC. It detects the electrical resistance exerted between the registration contact 73 and the grounding contact 71 by any device mounted on the housing 10. Since each device has a unique resistance, the control device 130 can determine which device is installed, if any.

As shown in FIG. 4, the control device 130 may be removably mounted in the housing 10 through an inlet 140 on a lower surface 54 of the housing casing 30. The hole 140 is made specifically for installing and removing the control device 130, as indicated by the notation, in this case the inscription 143 on the tag located on the casing 30. The hole 140 makes it possible to replace the user control device 130, which may occur if the control device 130 is damaged , or an advanced control device is supplied by the manufacturer. Due to its size and / or location, the hole 140 is not used to replace the motor 88, fan 80 and other elements of the housing 10. In fact, due to their location and / or size, these elements cannot be removed through the inlet 140. The user is not recommended to replace these elements, since this will require disconnecting the upper compartment 32 of the casing from the lower compartment 34 of the casing, which is more complicated than opening the inlet 140.

The control device 130 includes a printed circuit board 144 attached to an electrical connector 146, which is connected to an electrical connector 148 in the housing 10. Moving the printed circuit board 144 through the hole 140 towards its mounting position in the housing 10 and moves the printed circuit board connector 146 in the direction to mechanical and electrical connection with the connector 148 of the housing and into it. The converse is also true in that the movement of the connector 146 of the control device towards the connection with the connector 148 of the housing and into it moves the control device 130, including its printed circuit board 144, to its installation position. In its mounting position, the printed circuit board 144 is fixed in place relative to the housing casing 30, since its connector 146 is rigid and attached to the printed circuit board 144, and the housing connector 148 is rigid and attached to the housing casing 30. The connectors 146 and 148 thus support the control device 130 in place, in addition to connecting the control device 130 to the electrical elements of the housing 10.

The control device 130, as received from the manufacturer, is permanently attached to the cover 150 shown in FIGS. 4 and 5. This reduces the number of parts that the user must separately deal with and monitor when replacing the control device 130. In its installation position, the cover 150 is located in the recess 152 of the casing 30 of the housing, located on top of the casing 30 and covering the hole 140. On the plate 150 is provided a designation that is visible to the user when the cover 150 is installed, defining a control device 130, such as an indication of the model of the device 130 management. The designation may be the inscription 153 or the symbol or color indicator of this model.

The cover 150 is designed in such a way that moving the cover 150 towards its installation position and into it moves the control device 130 towards its installation position and into it, which in turn moves the electrical connector 146 of the control device towards the mechanical and electrical connection with electrical connector 148 of the housing and into it. The converse is also true in that the movement of the control device 130 through the opening 140 towards its installation position and into it moves the cover 150 towards its installation position and into it.

The cover 150 may be secured to the casing 30 with screws 154. The control device 130 attached to the cover 150 is secured in its installation position with screws 154, as well as by connecting the connectors 146 and 148. The cover 150 is not visible when the housing 10 moves along floor 6, since it is located on the lower surface 54 of the housing 10, which faces the floor 6.

The nozzle 12 comprises a brush roller 202 driven by a drive pulley 90 to rotate on floor 6 to remove dirt from floor 6. Fan 80 creates an air stream that moves dust from the floor 6 through the nozzle 12 and the lower inlets 48 to the housing 10. Air containing dust exits the housing 10 through the outlet 105. The lamp 210 of the suction nozzle 12 is powered by electricity supplied to the housing 10 through the ground terminal 71 and output contact 72, rated for 5V DC (figure 2).

The nozzle electrical assembly 14 comprises an electric nozzle 300 with a brush roller 302 driven by an electric motor 304. The electric nozzle 300 is connected to a rigid tube 374, which is connected by a flexible tube 376 to a connector 378 that is removably attached to the housing 10. During In operation, the user takes a rigid tube 374 to move the electric nozzle 300 along the floor 6. The brush roller 302 rotates along the floor 6 to remove dirt. The fan 80 creates an air stream that moves dirt from the floor 6 through the nozzle assembly 14 and the fan 80 and from the outlet 105. A lamp 390 on the electric nozzle 300 illuminates the floor 6 in front of the electric nozzle 300. The lamp 390 and the electric motor 304 respectively operate on 5V DC and 24V DC supplied to the housing 10 through electrical contacts 71-73 (figure 2).

The auxiliary sleeve 16 includes a flexible tube 400 extending from a connector 410 that is attached to the housing 10. During operation, the fan 80 draws air through the pipe 400 and the upper inlet 46 into the housing 10 and releases air through the outlet 105.

The detergent nozzle 18 includes front and rear brush rollers 501 and 502, driven by the drive pulley 90 of the housing when the nozzle 18 is supported on the housing 10. The detergent is applied to the carpet 6 using a metering device 504 for the detergent nozzle 18 and rubbed into carpet 6 using brush rollers 501 and 502 to remove dirt from carpet 6. Detergent is removed from carpet 6 using the rear brush roller 502 and is collected in a receiving tray 506 in nozzle 18.

Vertical handle assembly

The node 20 of the vertical handle shown in Fig.6. It contains a vertical handle 602 attached to the bracket 100 of the housing, and a dust collecting container 604 attached to the exhaust outlet 105 for receiving air containing dirt coming out of the housing 10. The vertical handle assembly 20, the housing 10 and the suction nozzle 12 together comprise a vertical type vacuum cleaner . This type of vacuum cleaner is configured in such a way that the user can stand upright when moving the vacuum cleaner manually using the handle on the floor 6 to clean the floor 6.

The handle 602 has a handle 610. The force sensor 612 in the handle 610 determines the direction and magnitude of the force exerted by the user to move the vacuum cleaner across the floor.

Knob 602 also includes a user interface panel 640. The panel 640 contains user interfaces 642 (FIG. 1), including controls and a display, through which the user is in communication with the control device 130. The controls are designed to manually select the operating mode of the vacuum cleaner, such as driving, selecting the rotational speed of the electric motor, engaging the clutch and actuating the drive motor. The display shows the operating mode of the vacuum cleaner, such as the speed of the electric motor, the actuation of the brush roller, the actuation of the drive motor and the filling of the filter bag.

The multi-pin electrical terminal 630 on the handle 602 is connected to the terminal 124 of the housing 10 to connect the control device 130 to the electrical elements of the handle 602. Through the terminal 630, the handle 602 provides a signal to the control device 130 to confirm itself as a vertical handle. Two hooks 634 and a lever 638 secure the handle 602 to the bracket 100 of the housing 10.

During operation of the vacuum cleaner, the control device 130 inputs the operating parameters of the vacuum cleaner from various sensors and switches of the vacuum cleaner. Especially from the force sensor 612 in the handle 610, the control device 130 inputs the direction and amount of force applied manually to the handle 602. From the handle position sensor 120, the control device 130 determines whether the handle 602 is in a vertical or inclined position. From the control panel 640, the control device 130 determines which switch the user presses and what type of handle is installed. From the mounting sensor 76 (FIG. 2), the control device 130 determines whether the upper inlet 46 is closed by a cleaning device. By registering the electrical resistance between the ground terminal and the resistance registration terminal 71 and 74 (FIG. 2), the control device 130 determines which cleaning agent is installed.

The control device 130 controls the operation of the vacuum cleaner based on parameters input from sensors and switches. For example, the control device 130 uses a higher default speed of the electric motor when the auxiliary sleeve 16 is connected (FIG. 1) than when the suction nozzle 12 is connected. The control device 130 engages with the coupling 98 (FIG. 3) to connect the motor 88 to the drive pulley 90 only when the handle is installed when installing either the suction nozzle 12 or the nozzle 18 for cleaning with detergent. The control device 130 will not operate the motor 88 if a handle is not installed, or if a cleaning device is not installed. The control device 130 drives the drive motor 99 (FIG. 3) to rotate the rear wheels 52 in a direction and at a speed that correspond respectively to the direction and magnitude of the force manually applied to the handle 602, to facilitate the movement of the housing 10 by the user on the floor 6. Device The control unit 130 drives the drive motor 99 only when both the suction nozzle 12 or the nozzle 18 for cleaning with detergent are installed, the vertical handle 602 is installed and tilted, and off The power cord on the control panel 640 is pressed.
