Abstract

A domestic appliance, such as a cyclonic vacuum cleaner (1), comprises a component, such as separating apparatus (3), carried by a chassis (2). A catch (11) is provided and is operable to release the component from the chassis. The component and the chassis are able to move slightly with respect to each other. When the appliance is lifted there is relative movement, against the force of resilient means, between the component and the chassis, so that the catch (11) occupies a position that inhibits its release. Previous proposals for catches inhibited from release when the appliance is lifted had a drawback in that slight relative movement between the component and the chassis when the appliance was resting on a surface tended to put the catch into the unreleasable position. For example, it was found that the action of grabbing the handle on the collecting chamber of a vacuum cleaner was sometimes sufficient to urge the catch into the locked position. The provision of resilient means provides some resistance to the catch moving into the locked position, thereby ensuring that the catch is inhibited from release only when the appliance is lifted from a surface.

Description

Technical field
The present invention relates to household electrical appliance, for example vacuum cleaner.
Background technology
Do not use the vacuum cleaner (so-called bagless vacuum cleaner) of filter bag to become general gradually from flow separation dust.Most nothing bag dust catchers use whirlwind or centrifugation that dust is screwed out from air-flow.By avoiding using filter bag as main unpack format, even the suction of the higher level of having found to keep consistent is when collecting chamber is filled dust.
In typical Cyclonic vacuum cleaner, the air-flow that wherein carries dust enters first cyclone separator via tangential inlet.This inlet causes air-flow to be advanced along spirality or helical-like path in collecting chamber, so that dust is from flow separation.The air of cleaning passes this chamber relatively, and the dust of Fen Liing is collected in this chamber simultaneously.In some Cyclonic vacuum cleaners, air-flow passes second cyclone separator subsequently, and this separator can separate trickleer dust than upstream cyclone.Air-flow is cleaned to higher degree thus, so that when obtaining air-flow and leaving cyclone separator, air-flow almost completely is not with dust granule.Dust is stayed collecting chamber inside.
When collecting chamber became full, the user removed collecting chamber usually from the machine frame, this chamber be transplanted on dust case or zona detritus and the chamber content be emptied to this case or bag in.This chamber can be reversed emptying.Alternatively, the manual operation fastening hook mechanism can unclamp the base portion in chamber so that dust from the chamber drop out case or the bag in.
Typically, provide one handle, so that the user can be easily be transplanted on case or bag to collecting chamber, with its emptying.Be easily, the same handle can be used for lifting whole vacuum cleaner when collecting chamber is connected to frame by the user, so that transfer this dust catcher between diverse location.

The specific embodiment
With reference to figure 1, generally the upright vacuum cleaner by label 1 expression comprises mainframe 2, and its support is associated with the separator 3 of collecting chamber 4.The bottom of vacuum cleaner 1 comprises and is used for the Floor nozzle of duster 5 that cooperates with ground.Floor nozzle of duster 5 has suction inlet and the brush bar (not shown) of facing downwards, is installed on the mouth of inlet, is used to stir ground.Floor nozzle of duster 5 is pivotally mounted to motor shell 6, and this motor shell 6 takes up the motor and the fan of dust catcher 1.The both sides that support wheel 7 is installed to motor shell 6 are used to support dust catcher 1 and allow to move on the ground.
The spine 8 of frame 2 extends upward from motor shell 6, thinks that the parts of dust catcher 1 provide support.Dust suction rod 9 with second dirty air intake 10 is connected to the bottom of the spine 8 of frame 2 by the flexible pipe (not shown).Rod 9 can unclamp the position dust suction of carrying out the floor dust suction and can not arriving in main cleaner head 5 with the permission user from spine 8.When rod 9 was fixed to spine 8, clavate became the handle of dust catcher 1.The excellent handle part 9 ' of the far-end excellent 9 allows the user to handle dust catcher 1.
In the present embodiment, as shown, dust-separating appliance 3 comprises cyclone, but its combination that can easily be filtered device, bag or different known different separators replaces.
In normal vertical use, vacuum cleaner 1 is wanting mobile on the ground of dust suction, and motor makes dirty air be inhaled in the dust catcher 1 via Floor nozzle of duster 5 simultaneously.Dirty air passes dust-separating appliance 3, and dust is extracted and clean air is discharged into atmosphere there.
Dust is collected in the collecting chamber 4 of separator 3 and when it is filled to be needed by emptying regularly.Therefore, separator 3 can discharge from mainframe 2.The fastening hook mechanism that can manually unclamp (catch) 11 is arranged in the spine 8 of frame 2 and this fastening hook mechanism 11 is configured to a separator 3 (comprising collecting chamber 4) and is positioned on the equipment.User's release catch mechanism 11 of vacuum cleaner 1 and remove separator 3 by the handle 12 that is arranged on the separator.The user is transplanted on litter-bin or bag to separator 3 with its emptying by handle 12 then.Collecting chamber 4 can be drained by making it unclamp and on case or bag it be put upside down from separator 3.Alternatively, collecting chamber 4 can have moveable base portion, and it can be unclamped by another fastening hook mechanism that can manually unclamp, to allow the bottom dropped out of dust from collecting chamber.
Handle 12 on the separator 3 also is used to allow the user that this equipment is lifted as a whole and transfers, as shown in Figure 3.When the user did like this, the close fastening hook mechanism 11 of his hand was to unclamp separator 3 from frame 2.For conventional vacuum cleaners, there is the danger of user's unexpected release catch mechanism when transporting apparatus 1.
The fastening hook mechanism 11 of the vacuum cleaner that makes up according to the present invention is shown in Fig. 4 to 7.Fastening hook mechanism 11 comprises main card hook part (main catch member) 13, has pivot 14 in the bottom of this main card hook part 13, so that it is pivotably connected to spine 8.The central part 15 of main catch member has the flange 16 that dangles downwards from the outside protrusion of spine and at its free ending tool.The top of main card hook part 13 comprises the actuator that is used for fastening hook mechanism 11, and this actuator is the form of user-operable button 17.Button 17 is positioned at easily to be transferred near the handle 12.When the user promoted button 17, main catch member 13 pivoted and leaves the user, and towards spine 8, and the protuberance 15 of main catch member is raised.The elastic device of helical spring 18 forms is arranged between the protrusion flange 19 in the spine 8 of the central part 15 of main catch member and frame.
Fig. 4 shows fastening hook mechanism and is in it and closes or clamped position, and wherein separator 3 is connected to frame 2.Flange 16 on the central part 15 of the protrusion of main catch member 13 is configured to cooperate with shoulder 20 on the separator 3.When the user wanted to unclamp separator 3, he promoted the power of button 17 antagonistic springs 18.This causes main catch member 13 to move and the rear surface 23 of clamping member 13 moves in the chamber 21 in the spine towards spine 8 pivotally.This is shown in Figure 5.The part 15 of the protrusion at center upwards pivots, and leaves the top of the shoulder 20 on the separator until flange 16.The motion backward that part limits the rear surface 23 of clamping member 13 himself ends as shelves in spine 8.The bottom 22 of main catch member 13 is configured to make, when clamping member when spine 8 pivots, the bottom is pressed against separator 3, when fastening hook mechanism 11 is released it is pushed away frame 2 thus.This feature helps the user to remove parts.
When separator 3 or other parts were released, actuator 17 was stayed on the frame 2.If actuator be positioned at these parts from one's body, when another grab on the parts that the user attempts to operate or mechanism's (for example in order to the actuator of release catch), can cause and obscure with the emptying collecting chamber.
When the user wanted to reconnect separator 3, he back into position on the frame 2 to separator 3 simply.When he did like this, pivotal part 13 was pushed rearward until it and leaves shoulder 20 on the separator 3.Spring 18 turns back to its stand up position to main catch member 13, and the flange 16 of protuberance 15 is engaged on the shoulder 20 related with separator 3.Therefore, separator 3 is fixed to frame 2.
Fastening hook mechanism is configured to make can be with a mode relative motion between permission separator 3 and the frame 2, and this mode is for when equipment 1 is lifted by handle 12 by the user, and fastening hook mechanism 11 occupies one and prevents the position that it unclamps.With reference to figure 6 and 7, separator 3 and frame 2 are configured to make and allow between them limited amount relative motion is arranged, typically less than 0.5cm.When the user applies when lifting power by 12 pairs of equipment of handle, when equipment was lifted overhead, separator 3 can be moved up a little with respect to frame 2.The bottom of clamping member 13 is set for a separator 3 and is supported on lifting position.
According to the present invention, when equipment 1 was raised, separator 3 was with respect to frame 2 motions, and whole fastening hook mechanism 11 moves with separator under the effect of the power of helical spring 18.In this embodiment, separator 3 and fastening hook mechanism 11 all move upward with respect to the spine 8 of frame 2.Main catch member 13 occupies a position, and this position is close spine 8 of at least a portion of its rear surface 23 and the position of leaving the chamber 21 in the spine.Therefore, if the user unexpectedly promotes button 17, main catch member 13 can not pivot backward, because its rear surface 23 is against the spine 8 of frame.The motion of main catch member 13 is prevented from, and therefore button 17 provides an indication for the user, and promptly fastening hook mechanism 11 can not be operated when equipment 1 is picked up.
Fig. 7 shows in detail fastening hook mechanism.The catch stop of flange 24 forms is arranged on the frame 2, moves to a position to prevent clamping member 13, and fastening hook mechanism 11 can unclamp when equipment 1 is picked up in this position, even this equipment is shaken or is subjected to some unexpected power.Groove or flange in the rear surface of flange 24 cooperation clamping members 13.If the user attempts release catch mechanism 11 when vibrations equipment 1, clamping member 13 can vertically move against spine 8, moves to the position near chamber 21 vertically downward but flange 24 prevents clamping member, and it can be pivoted to the released position there.
Spring 18 among Fig. 6 and 7 is compressed and bias voltage, to shift the position that fastening hook mechanism 11 can be released downwards onto at following clamping member 13 of the situation that does not have external force and separator 3.But when equipment 1 was picked up, spring force was not enough to do like this, this be because the gravity reaction of frame 2 on spring 18.Spring 18 or other elastic device provide a reaction force, and it prevents that separator 3 from unexpectedly being lifted to and suppresses the position that fastening hook mechanism 11 unclamps.For example, if the user catches handle 12 and attempts separator 3 is lifted the frame 2 and when attempting to open fastening hook mechanism 11 simultaneously, the user may inadvertently apply power vertically upward of disembarking.Do not having spring 18 clamping member 13 (separator 3 thus) when pushing away downwards, the power of lifting is enough to fastening hook mechanism is advanced to configuration shown in Figure 6 from configuration shown in Figure 4, prevents that thus accident from unclamping.
Spring 18 or other elastic device are multi-functional: it turns back to its initial position to actuator 17 after being compressed, its clamping member 13 turns back to clamped position, so that separator is fixed to frame 2, and as mentioned above, it prevents that fastening hook mechanism 11 from unexpectedly moving to the position that inhibition is unclamped.By using a spring 18 to carry out a plurality of functions, making the part number that is used for making fastening hook mechanism 11 can be reduced.
When the user placed equipment 1 on the ground downwards, clamping member 13 and separator were with respect to frame 2 downward travelling backwards and occupy its normal position, as shown in Figure 4, so that separator can unclamp from frame once more.
Certainly, can change and do not leave scope of the present invention.For example, elastic device can be arranged between parts and the spine.Independent elastic device can be set to be come clamping member is turned back to clamped position and actuator turned back to its initial position at switch when released.
Be used for the equipment that lifts handle needn't be used for transferring the identical of separator.Independent handle or handle can be set.Being used for the handle of the equipment that lifts can be arranged on the frame, and in this case, switch is reset needs so that switch and parts with respect to the downward relative motion of frame cause switch occupy one its unclamp repressed position.
Fastening hook mechanism of the present invention can be set up, with other positioning parts on frame, so that these parts can not unclamp when equipment is transferred.
Although the present invention is described with reference to upright vacuum cleaner, it can equivalence be used for the equipment that cylinder cleaner and other can be transferred by the user.For example, hay mover can be provided with frame and the chamber that is used to collect the grass bits of cutting off.The present invention can be used to prevent that collecting chamber is released when the user transfers hay mover.The present invention also is applicable to for example other surface processing equipment, for example is used to polish the equipment with the application surface.
