Vacuum Cleaner
This invention relates to a vacuum cleaner, and in particular to an upright vacuum cleaner having a cleaner body that can be separated from a frame.
5
An upright vacuum cleaner is convenient to clean large areas such as a broad floor. However, an upright vacuum cleaner is not convenient to clean cumbersome surfaces such as a narrow space, a top surface of furniture, or a ceiling. Improved upright vacuum cleaners to overcome such shortcomings have been proposed in Korean Patent 10 Applications Nos. 10-474081, 10-474083 and 10-474087. In the improved upright vacuum cleaners, a cleaner body can be separated from a cleaner frame, so that cumbersome surfaces can be cleaned by carrying only the separated cleaner body.
In these improved upright vacuum cleaners, a nozzle unit for picking up dust from a 15 surface to be cleaned is pivotably mounted to the frame of the cleaner, and the cleaner body is removably connected to the frame. Such a nozzle unit may have a light for the user's convenience. In order to supply power to the nozzle unit and the light, the nozzle unit and the cleaner body are electrically connected by wiring.
20 Conventionally, an electrically-wired plug is mounted on the nozzle unit and a complementary socket is mounted on the cleaner body, so that the cleaner body and the nozzle unit can be electrically connected by the plug and the socket.
However, when the cleaner body is repeatedly separated from the nozzle unit, the
2
durability of the wiring device can deteriorate. In other words, without a dedicated structure for supporting the electric wires connected to the plug and the socket, a load generated during separation and mounting of the cleaner body may act on the electrical connections to the plug and the socket, thereby breaking the electrical connection. 5 Moreover, when the plug and the socket are assembled without any dedicated insulation, sparks may be generated by short-circuits on connection.
An aim of the invention is to provide an upright vacuum cleaner of this type which does not lead to the generation of sparks and short-circuits even following frequent separation 10 and re-connection of its cleaner body and its nozzle unit.
The present invention provides a vacuum cleaner comprising:
a nozzle unit;
a cleaner body detachably mounted on the nozzle unit, the cleaner body being 15 provided with a suction fan for generating a suction force and with a dust receptacle for collecting dust; and first and second connector units associated respectively with the nozzle unit and the cleaner body;
wherein the first and the second connector units are connected so that electricity is 20 supplied to the nozzle unit when the vacuum cleaner is used with the cleaner body mounted on the nozzle unit, and are disconnected so that the electricity is not supplied to the nozzle unit when the cleaner body is detached from the nozzle unit, and the first connector unit comprises,
a plurality of plug pins connected to an electric cable,
3
a pin housing having a plurality of spaced connection grooves for mounting the plug pins, and a plug support for fixing end portions of the plug pins in the first connector unit.

Each connection groove may include a support part which supports a stepped portion 10 formed on the outer circumferential surface of the respective plug pin.
Advantageously, the first connector unit, in which the plug pins, the pin housing and the plug support are assembled, is provided with an exterior of moulded polyvinylchloride.
15 In a preferred embodiment, the second connector unit comprises:
a plurality of pin sockets for receiving the plug pins;
an outlet cover supporting one end of each of the pin sockets; and a pin socket housing supporting the other end of each of the pin sockets.
20 The outlet cover may comprise a plurality of hollow depressions for receiving and fixing the pin sockets.
Three plug pins and three pin sockets may be provided to supply power for different objects, respectively.
The invention also provides a vacuum cleaner comprising:
a nozzle unit;
a cleaner body detachably mounted on the nozzle unit;
a first connector unit having a pin housing around a plug pin, the plug pin being in electrical communication with a first electric wire at a first connection point, the plug pin having a first portion extending from a via hole of the pin housing and a stepped portion in the pin housing; and a second connector unit having an outlet cover around a pin socket, the pin socket being in electrical communication with a second electric wire at a second connection point, the outlet cover having an end through which the second electric wire passes,
wherein the plug pin and the pin socket are connected so that the first and second wires are in electrical communication when the cleaner body is mounted on the nozzle unit and are separated so that so that the first and second wires are not in electrical communication when the cleaner body is separated from the nozzle unit, and wherein the arrangement is such that the stepped portion of the plug pin is prevented from being withdrawn from the pin housing through the via hole so that no load is applied to the first connection point when connecting and separating the plug pin and the pin socket.

In the following description, the same reference numerals are used to identify the same or similar elements in the different figures. The matters set forth in the description below, such as the detailed construction and method of operation, are only provided to assist in a comprehensive understanding of the invention, and should not be considered as limiting. 20 The present invention can be carried out without using some or all of those defined elements. Well-known functions or constructions are not described in detail to avoid obscuring the invention in unnecessary detail.
Referring to the drawings, an upright vacuum cleaner comprises a frame 10, a nozzle unit
6
20, a cleaner body 30 and a seating guide 40. The frame 10 constitutes an exterior skeleton of the upright vacuum cleaner, and has a handle 13 for a user to grip at an upper part thereof. The cleaner body 30 is detachably connected to the centre portion of the frame 10.
5
The nozzle unit 20 is pivotably mounted to the lower portion of the frame 10. The nozzle unit 20 includes a rotary brush 23 for separating dust from a surface to be cleaned by beating that surface, and a light 25 for use when cleaning dark places.
10 The seating guide 40 is disposed between the nozzle unit 20 and the cleaner body 30, so as to prevent the cleaner body from unintentional release from the frame 10. As shown in Figure 2, the seating guide 40 is provided with a first socket 41 which defines a dust flow path 42, and with a support projection 43. The first socket 41 is equipped with a plug unit 110 for supplying power to the rotary brush 23 and to the light 25.
15
The path 42 guides dust-carrying air, which is drawn in through the nozzle unit 20, into the cleaner body 30. The support projection 43 supports the lower portion of the cleaner body 30, so as to prevent the cleaner body from unintentional release from its position on the frame 10.
20
The cleaner body 30 is provided with a vacuum fan (not shown) for generating a negative pressure, and with a dust receptacle (not shown). As shown in Figure 3, the cleaner body 30 comprises a second socket 31 having a complementary form to the first socket 41 for mating engagement therewith. The second socket 31 defines a second dust flow path 32
7
which is contiguous with the first dust flow path 42 when the two sockets are in mating engagement. The second socket 31 has a support groove 33 which complements and receives the support projection 43. A socket unit 120 is associated with the second socket 31 for connection to a power supply unit. The socket unit 120 is connected to, and 5 disconnected from, the plug unit 110 as the cleaner body 30 is connected to, and separated from, the frame 10.
When the vacuum cleaner is used with the cleaner body 30 mounted in the frame 10 above the nozzle unit 20, the nozzle unit is supplied with electricity by connection of the 10 plug and socket units 110 and 120. When only the cleaner body 30 is used, when separated from the nozzle unit 20, the nozzle unit is cut off from the power supply by disconnection of the plug and socket units 110 and 120.
As shown in Figures 4 and 5, the plug unit 110 has a first terminal 111, a plug 112 and an 15 electric cable Wl. As shown in Figure 2, the plug unit 110 is mounted in the first socket 41. The first terminal 111 is connected to a drive motor (not shown) transmitting power to the rotary brush 23, and to the light 25. The first terminal 111 is connected with the plug 112 by the electric cable Wl.
20 The body of the plug 112 is formed by moulding polyvinylchloride (PVC). The plug 112, is provided with three plug pins 113 (see Figure 5) mounted in a pin housing 114 and a plug support 115. The plug pins 113 are made of an electrically-conductive material, and are connected to the three wires of the cable Wl.
8
The three plug pins 113 are constituted by a pin for supplying power to the drive motor which operates the rotary brush 23, a pin for supplying power to the light 25, and an earth pin. As shown in Figure 5, each plug pin 113 is formed stepwise in diameter such that a first portion 113a mounted in the pin housing 114 has a larger diameter than a second 5 portion 113b which projects to the outside of the pin housing.
The pin housing 114 is made of a non-conductive material, and comprises a respective connection groove 114a, a respective via-hole 114b formed in the associated connection groove, and a respective support part 114c for each of the plug pins 113. Being 10 respectively received in the connection grooves 114a, the plug pins 113 are insulated from one another. Each plug pin 113 is inserted into the associated connection groove 114a via the associated via-hole 114b, and is exposed to the outside of the plug 112 by one end thereof. Each support part 114c supports a stepped portion 113c of the associated plug pin 113, that stepped portion being defined by the first and second 15 portions 113a, 113b of that plug pin, so as to prevent escape of that plug pin from the plug 112 through that via-hole. To this end, each via-hole 114b preferably has a smaller inner diameter than the largest diameter of the associated plug pin 113.
The plug support 115 fixes the plug pins 113 which are seated in the connection grooves 20 114a, and comprises plug pin support projections 115a formed to correspond to the plug pins 113 and fit into the connection grooves.
Since the plug pins 113 inserted in the connection grooves 114a are fixed between the support parts 114c and the plug pin support projections 115a, the plug pins 113 do not
9
move during separation and connection of the plug unit and the socket 120. Accordingly, no load is applied to the connections between the wires of the electric cable Wl and the plug pin 113 when connecting and separating the plug 112. After assembling sequentially the plug pins 113, the pin housing 114 and the plug support 115, the exterior of the 5 assembly is overmoulded so that the plug pins and the electric cable Wl are firmly fixed. Accordingly, disconnection and short-circuit can be prevented.
As shown in Figures 4 and 6, the socket unit 120 comprises a second terminal 121, an outlet 122 and an electric cable W2. As shown in Figure 3, the socket unit 120 is mounted 10 in the second socket 31.
The second terminal 121 is connected to a power supply unit (not shown) formed in the cleaner body 30 to supply the power to the socket unit 120.
15 The exterior of the outlet 122 is implemented by moulding polyvinylchloride (PVC). The outlet 122 is provided with a respective pin socket 123 for each of plug pins 113, and with a pin socket housing 124 and an outlet cover 125. Each pin socket 123 is connected to a respective wire of the electric cable W2.
20 Each pin socket 123 is tubular, having an inner diameter corresponding to the diameter of the second portion 113b of the respective plug pin 113, so as to receive that plug pin 113 therein. The pin socket housing 124 supports the pin sockets 123, and is formed with apertures 124c which define seats for mounting the pin sockets.
10
The outlet cover 125 is provided with hollow depressions 125a for receiving the pin sockets 123 which engage with the pin socket housing 124, thereby insulating the pin sockets from one another. As shown in Figure 6, one end 127 of each hollow depression 125a, has a smaller diameter than the outer diameter of the associated pin socket 123 so 5 that the pin sockets are firmly fixed.
As described above, when the pin sockets 123 connected with the wires of the electric cable W2 are fixed between the pin socket housing 124 and the outlet cover 125, the pin sockets do not move, even during separation and connection of the plug pins 113 with respect to the pin sockets. Therefore, no load is applied to the electrical connections between the pin sockets 123 and the electric cable W2 when connecting and separating the plug pins 113. After assembling sequentially, the pin sockets 123, the pin socket housing 124 and the outlet cover 125, the exterior of the assembly is overmoulded so that the pin sockets and the electric cables W2 are firmly fixed. Accordingly, disconnection and short-circuit can be prevented.
As can be appreciated, the plug pins 113 of the plug unit 110 and the pin sockets 123 of the socket unit 120 are firmly connected with their electric cables Wl and W2, are insulated from each other by the respective inner structures, and the connections are not 20 exposed to the outside as their inner structures are covered by the PVC mouldings. As a result, the load generated by frequent separation and connection of the cleaner body 30 and the frame 10 does not act on the connection points between the electric cable Wl and the plug pins 113 or on the connection points between the electric cable W2 and the pin sockets 123, thereby preventing disconnection and short-circuit at the connection points.
