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 unrepeatable 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

200840536 IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a household appliance such as a vacuum cleaner. 5 [Prior Art] The vacuum cleaner of the so-called bagless vacuum cleaner has become more and more popular, which is to remove dirt and dust from the airflow without using a filter bag. Most of the 0 bagless vacuum cleaners use cyclone or centrifugal separation to swirl dirt and dust from the air stream. By avoiding the use of filter bags as the primary form of separation, 10 it has been found that it is possible to maintain a consistently high degree of suction, even when the collection chamber is full of dirt and dust. In a typical cyclonic vacuum cleaner, the entrainment of dirt and dust enters the first cyclonic separator via a tangential inlet. This inlet allows the airflow to follow the spiral or spiral path 15 in the collection chamber to thereby deposit dirt and dust from the airflow. Relatively clean air collects the deposited dirt and dust by leaving the chamber. In some cyclonic vacuum cleaners, the gas stream is followed by a second cyclone separator that is capable of depositing dirt and dust that is finer than the upstream cyclone. Thereby, the purge gas is flowed to a greater extent so that when the gas stream exits the cyclone separation device, the gas stream is almost completely free of dirt and dust particles. Dirt and dust remain in the collection room. When the collection chamber is full, the user typically removes the collection chamber from the machine rack, takes the chamber to the dust box or trash bag and pours the contents of the chamber into the box or bag. It can be emptied by reversing the chamber. Alternatively, the bottom portion of the chamber can be used by hand to allow the dirt and dust to fall from the chamber into the box or bag. Usually, a handle is provided so that the user can easily carry the collection room to the box, and the clothes are used for money. For convenience, when the collection chamber (4) is in the rack, the vacuum cleaner can be lifted up by the same handle to bring the π vacuum cleaner to different positions. A problem encountered with such equipment is that when the user carries the device with the handle m, the cassette that secures the collection chamber to the frame is accidentally released. Therefore, the rack may be completely loosened with the chamber and the 10 15 20 rack may also cause inconvenience, and may also damage the use of two:: phase difference [invention] The present invention provides a household appliance, which includes - a component that is carried with: and an operable to make the component accessible; = 荀 'the frame is configured to: when the device is lifted, I, and the piece and the frame will move relative to each other to overcome the elasticity The force, so that the cut can be restrained from loosening its position. When the door is lifted, it will overcome the elastic member and will not loosen the card ^ to prevent the frame from accidentally separating from the assembly. When lifting, the cartridge can be restrained from being loosened: when the lower equipment is placed on the plane, the slight relative movement of the component and the day of the casing 1 will cause the card to enter the unremovable column enough to accidentally urge the card. 7 200840536 will confuse the user, especially in an attempt to loosen the collection room to empty it. The _L elastic member can provide some resistance for the card that will move into the flash position, thus Ensure that only when lifting the device from the plane Suppressing the release of the card. ^ f is advantageous for the following components, the member being configured to push the assembly away from the frame when the card is released, thereby assisting the user in removing The assembly is preferably a user operable actuator. For ease of use, 'it can be provided with a handle for carrying the assembly when the assembly is released, the elastic member& To press the + cylinder into the vertical position and release the actuator to return to the original position. A limiter (st〇p) can be installed, so that when the cartridge is in the unrecognizable 15 20 2 The limiter can be carded to open when the device is subjected to sudden vertical movement. This feature prevents the jam from returning to the position, even if the device is shaken. The straightforward can be used especially in vacuum cleaners. When the user carries the stolen, the present invention prevents the user from separating the separating device including the collection chamber for collecting the dirt, and the rack. For: user: carrying the device. When the present invention should be When the eight-vacuum cleaner is used, this handle can also be used when the separation I is removed from the rack. The handle for carrying the separation device. 8 200840536 [Embodiment] The present invention will be described with reference to an example of the accompanying drawings.

Extends from the motor casing 6 to support the suction ridge: 8 " cattle. The cleaning rod 9 of the second dirty air inlet 10 is connected to the frame 2 by a hose (not shown) at the bottom of the column 8. The rod 9 iiii is loosened so that the user can perform cleaning above the floor and 4, where the main & head 5 is inaccessible. When the rod 9 is fixed to the spine 8, the rod forms the handle of the cleaner 1. The handle at the distal end of the rod 9 allows the user to move the vacuum cleaner 1. In the illustrated embodiment, the dirt and dust separating device 3 comprises a milking configuration, but it is easily replaced with a filter, a bag or a combination of conventional separating devices.

In the normal use of the upright type, the vacuum cleaner 1 is moved on the surface of the floor to be cleaned while the motor draws dirty air into the cleaner 1 via the dust removing head 5. The dirty air flows to the dirt and dust separating device 3 which extracts dirt and dust and discharges clean air to the atmosphere. I 9 200840536 5 10 15 20 The collection chamber 4 of the separation device 3 collects dirt and dust and needs to empty it on time when it is full. Therefore, the separating device 3 can be separated from the main chassis 2. The hand-releasable card is mounted on the spine 8 of the frame 2 and is configured to position the separation device 3 (including the collection chamber 4) on the device. The user of the vacuum cleaner 1 releases the card shoots and removes the separating device 3 with the handle 12 sighing the upper half of the separating device. Then, the handle 12 is used to carry the separation device 3 to the trash can or bag for cleaning. It can be emptied by releasing the collection chamber 4 from the separation device 3 and inverting the collection chamber 4 over the waste bin or bag. Alternatively, the collection chamber 4 can be 2f a releasable movable bottom portion which is retracted by another hand to allow dirt and dust to fall from the bottom of the collection chamber. The handle 12 of the separating device 3 is also used to allow the user to lift and carry the =, sigh, as shown in Figure 3. When the user does this, the hand is 2 used to separate the separating device 3 from the frame 2, and the user may accidentally release the card when the user is carrying the device. Vacuum vacuum (four) card 荀 U schematic diagram. The cassette 11 includes the main card member member. The main card has a pivot 14 that allows it to be pivotally coupled to the spine. The free end has a 曰6:: the central portion 15 projects outwardly away from the spine and is flanked by a lip 16 that hangs downwardly. It contains the upper part of the box for the use of the card. The form is the actuating benefit of the user operable button 17. When the button 17 is placed on the handle of the carrying handle, the main cutting member is convenient. When the pivoting member 8 is used to pivot away from the spine 8, the spring member of the main spring 15 is disposed outside the main blade 15. The Yin Yang portions 15 and 5 of the dancing piece in the form of the protruding lip 19 on the spine frame S are shown in the closed or latched > device 3 attached to the frame 2. In the center of each member of the main card, the lip 16 of the separation 15 is engaged by the central portion of the dog. When the user wants to move the knife away from the shoulder 20 10 15 20 20 force on the device 3, the illusion 7 is pushed. This causes m' to pivotally move against the spring μ 8 and to allow the card to construct the pocket 2 i to the spine. ^ The rear surface of the jaw 2 3 moves into the spine 1 The map is not in Figure 5. In the water, the mountain is like a turn until the lip 16 is out of the second. 15 injured 15 up the pivot Q,, Tian Li 4 placed on the top of the shoulder 20. The private label 8 itself acts as a limiter to limit the card two top two = movement. The main card mailing member 13 is dipped and the rearward member of the rear surface 23 is arranged to the spine 8 ^ M, + ° 22 to be configured to: when the card is used, the second half will force the lower half against the separating device 3, the user Push it away from rack 2 when unloading. This feature assists in the addition of the rt to the device 3 or other components when the actuator 17 is still in the product. If the actuator is located on the component itself, when the user asks for the wood and attempts to identify another card shoot or mechanism on the component, this will be mixed with the user's use, for example, to open the card for use in the collection room (4) When it is desired to reattach the separation device 3, simply separate the device 3 into the position of the frame 2 backward. When he/she does this, the pivotable member 13 is pushed back until it vacates the shoulder 20 on the separation device 3 π 200840536. The spring 18 returns the main cartridge member 13 to its upright position and the lip 16 of the canine portion 15 will engage the associated shoulder. Therefore, the separating device 3 can be fixed to/mount 5 10 15 20 竿 2: pair 2 (four): set to allow the separating device 3 to move in the following manner. Although the user lifts the device 1 with the handle 12, the card =11 is stationed in a position that can suppress it from being released. Please refer to Figure 6 "" y knife off device 3 and frame 2 are configured to make them finite, usually less than - cm. When the two = south handle 12 applies a lifting force to the device 1, the separation device frame 2 moves slightly upward when the device is lifted off the ground. The card part = 3 lower half 22 is configured to be supported in the raised position: the separation frame = = : = high: the gram separation device 3 will overcome the screw magazine SS 士The separation device moves together. In this specific v^ force

= Both of the card shoots U will move the UJ upwards for the spine 8 of the rack 2 and prepare the ridges in the skin: at least a portion of the surface 23 is adjacent to the spine 8;; because: if the user: 匕The rear surface 23 is moved by the spine cover 13 next to the frame, so that the button 17 can provide the user with an indication that the card shoot 11 will be inoperable. ', ° is also prepared to break, Figure 7 shows the card shoots in more detail. The opening + limiter is attached to the frame 2 to prevent the cartridge member; 3 shifting 12 200840536 5 When the device 1 is lifted, the card shoots n can be released, even if the device is shaken or suddenly has some other force. The lip 24 will engage the flange or groove of the rear surface 23 of the card member member. If the user attempts to release the card shoot 11 when the device is shaken, the card member 13 can move vertically against the spine 8, but the lip 24 prevents the card member from moving vertically downward into the position adjacent to the pocket 21. Here it can be pivoted into the released position.

20 卞 The springs 18 of Figures 6 and 7 are compressed and biased so that, under external force, the card member 13 and the separating device 3 can be pressed downward to release the position of the bamboo shoot 11. However, when the injury i is lifted, it will not be enough to do so because the weight of the frame 2 will resist the bomb. In addition, the elastic yellow 18 or other elastic members can provide a reaction force for::: from the device 3 Inadvertently lifted into the restraint card 苟u released from the dream Jin ^ such as 'If the user grabs the handle 12 and the Enterprise ® lifts the H set 3 leaves the rack 2 while intending to start without rebounding the bullet to force the card shoot u two: t device 3) downward 'lifting force may be enough to figure 3', the configuration of the 4th picture becomes the picture shown in the 6th, and evil, hunting this can prevent accidental release. will make 2 = him The elastic member is of a multi-function type: after being pressed, it returns to r:2; 7 and returns to the original position, which causes the card holders 3 to return to the second position, and the hunting device fixes the separating device to the frame 2, as described above. , Carding 11 accidentally moved into the preparation # by using - a bomb (four) to achieve a variety of::: system #, position. The number of components of the card bamboo shoots., Li Yue, can be reduced for manufacturing 13 200840536 when the user When the device i is placed back on the floor surface, the cassette member i3 and the separating device will move back down for the frame 2 and remain in their normal position. The position, as shown in Fig. 4, allows the separating device to be separated from the frame again. - Wood 5 Of course, variants can be made without departing from the scope of the invention. For example, elastic members can be placed in the assembly and the spine. An intermediate elastic member may be provided to return the card member to the latched position and return the actuator to the original position after the cassette is released. The handle for lifting the device does not need to be used to carry the separation device. 1〇 is the same. It can be equipped with individual handles or handles. It can be used to lift the handle of the l. It can be a and on the rack. In this case, the card shooter will need to be reconfigured so that the card shoots and components are The relatively downward movement of the frame causes the card and the bamboo shoot to be in a position that inhibits its release. ~ The cartridge of the present invention can be provided for positioning other components on the frame 15 whereby the device is carried The components will not be loosened. The invention has been described using an upright vacuum cleaner, however the invention is equally applicable to cylindrical vacuum cleaners and other equipment that can be carried by a user.
