Patent Document 1: JP-A-2002-272656 (Page 3, Figure 4)

In the conventional electric vacuum cleaner described above, the two locking means are locked to the main body, and the filter cover is attached to the main body. However, at this time, the filter cover formed of resin is elastically deformed. In this way, the resin molded article is elastically deformed and then mounted, and the resin molded article is generally used. When the resin molded article is repeatedly elastically deformed, the elastic force is reduced due to fatigue remaining in the deformed portion, so that the locking force is weakened and used in the electric vacuum cleaner. In this case, the filter cover is detached unexpectedly, and the filter or the like cannot be held, and the problem of safety and durability is caused.

The present invention has been made in order to solve the above problems, and an object of the invention is to provide an electric vacuum cleaner which can easily perform a locking and releasing operation while improving the durability of a locking means of a filter cover and a main body.

The action diagram of the main part of the section is enlarged by the locking means.

In the respective drawings, the same reference numerals are given to the same or equivalent parts, and the description of the parts is omitted.

As shown in Fig. 6, the filter cover 11 is formed on the rear side of the main body 1 by a coupling member 24 formed by resin molding, and constitutes an upper casing 2 and an upper portion of the upper portion of the main body 1. When the link status is explained in detail, as shown in Figure 10, the link is as shown in Figure 10. The member 24 is press-fitted to the connecting member holding portion 34 of the upper casing 2 by elastic elasticity of the resin molded article, and is held by the claw hook portion 35.

The filter cover 11 is rotatably held so as to press the rotation shaft 32 integrally provided on the filter cover 11 into the rotation bearing receiving portion 36 of the coupling member 24, as shown in Fig. 7(b), with the rotation shaft 32. The center opens toward the rear at an angle of about 90 degrees.

Instead of using the connecting member 24, the receiving portion of the rotating shaft 32 holding the filter cover 11 may be integrally provided to the upper casing 2, but the upper casing 2 and the filter cover 11 also constitute an appearance part, and the rigidity is preferred. The material is detrimental to the appearance.

Moreover, when the appearance is prioritized, it may be difficult to select a material having high abrasion resistance. Therefore, when considering the aesthetics of the upper casing 2 and the filter cover 11, and ensuring the strength, rigidity, and wear resistance of the receiving portion of the rotating shaft, the connecting member is formed as a material having high strength, rigidity, and wear resistance. The other parts of 24 are preferably joined to the upper casing 2 and the filter cover 11. Further, in order to prevent the connecting member 24 as another component from being conspicuous, the color of the filter cover 11 or the like may be changed. In this manner, it is possible to realize a connection structure that ensures high durability, strength, rigidity, and wear resistance while ensuring the appearance of the upper casing 2 and the filter cover 11.

Further, in the embodiment of the present invention, as shown in Fig. 6, an example in which two connecting members 24 are provided is shown. However, the number of the connecting members 24 is not limited to two, depending on the size of the filter cover 11 to be set. Regardless of one or three, the number of uses can be appropriately selected in accordance with the specifications.

Then, in the filter cover 11, as shown in Fig. 7 (a), Fig. 8, The two pair of locking means 25 are provided at the end opposite to the side to which the upper casing 2 constituting the upper portion of the main body 1 is coupled. The filter cover 11 is engaged with the locking portion 26 provided in the upper casing 2 as shown in Fig. 7(b) by the respective locking means 25, and is locked to the upper casing 2.

According to Fig. 9(a), the locking structure is described in detail, and the locking means 25 integrally includes the locking release button 28 and the locking shaft portion 30, and the locking shaft portion 30 of the locking means 25 is swingably inserted into one body. The lock bearing receiving portion 29 of the filter cover 11 is provided.

The leaf spring 27 bent in a substantially V shape is provided between the back side of the lock release button 28 and the fixing member 37, and the biasing force of the leaf spring 27 acts on the locking means 25 by the force in the locking direction X. The locking shaft portion 30 is longer than the locking bearing receiving portion 29 by about 3 to 5 mm. Therefore, the front end portion of the locking shaft portion 30 protrudes from the end portion of the locking bearing receiving portion 29 by about 3 to the biasing force of the plate spring 27. 5mm.

Similarly, the lock release button 28 also protrudes from the opening of the filter cover 11 by the biasing force of the leaf spring 27. The protruding dimension of the opening of the locking release button 28 is equal to or larger than the maximum size of the distal end portion of the locking shaft portion 30 from the end portion of the locking bearing receiving portion 29, for example, when it is protruded by 5 mm, it is set to 5 mm or more. The size of the operation of the lock release button 28 is set.

The front end portion of the locking shaft portion 30 projecting from the end portion of the locking bearing receiving portion 29 by the biasing force of the above-described plate spring 27 is inserted into the locking portion 26 provided in the upper casing 2, so that the filter The unit 23 is housed between the filter cover 11 and the upper casing 2, and is fixed in a state in which the filter cover 11 and the upper casing 2 are locked (see Fig. 4).

Then, when the cleaner 100 is used, the dust collector 8 is always attached, and if the filter cover 11 and the upper casing 2 are forgotten, the dust collector 8 is also locked.

Fig. 11 (a) to (d) are views showing the operation of the locking means for enlarging the main portion of the cross section of the locking means 25. As shown in FIG. 11( a ), the inclined shape portion 31 is provided on the lower side of the front end portion of the locking shaft portion 30 in the direction toward the locking portion 26 . When the filter cover 11 is gradually pushed in the direction in the locking direction Y in a state where the lock release button 28 is not operated, the inclined shape portion 31 comes into contact with the corner portion 39 of the side wall 38 where the locking portion 26 is provided.

When the filter cover 11 is further pushed in from the state of contact, as shown in Fig. 11(b), the inclined shape portion 31 faces the side wall 38 of the locking portion 26 while resisting the biasing force of the leaf spring 27. The portion 39 slides, and the locking means 25 gradually moves toward the unlocking direction while resisting the biasing force of the leaf spring 27. Then, as shown in Fig. 11(c), the front end portion of the locking shaft portion 30 is gradually pressed into the locking direction while being in contact with the side wall 38.

When the locking shaft portion 30 comes to the position where the locking portion 26 is provided, as shown in FIG. 11(d), the locking shaft portion 30 enters the locking portion 26 by the biasing force of the leaf spring 27, and becomes a filter. The cover 11 and the upper casing 2 are locked.

In this manner, when the filter cover 11 is pressed in, the filter cover 11 and the upper casing 2 are locked, but as shown in Fig. 10, the press-fitting ribs 33 are provided to the dust collector 8. The press-fitting rib 33 is provided in a state where the dust collector 8 is attached, and is provided at a corner portion of the vicinity of the setting locking means 25 that contacts the filter cover 11 from above. s position.

Therefore, when the dust collector 8 is to be attached in a state where the filter cover 11 is not locked, since the press-fitting rib 33 comes into contact with the corner portion of the filter cover 11 in the vicinity of the installation locking means 25 during the mounting, the borrowing is performed. The press-fitting rib 33 presses the filter cover 11 in the locking direction.

Therefore, since the locking means 25 has the above-described configuration, even if the filter cover 11 is not locked, if the dust collector 8 is attached during use, the filter cover is installed during the operation of the dust collector 8. 11 is also locked, and the filter cover 11 is simply and surely locked at substantially the same timing as when the dust collector 8 is attached to the body 1.

In addition, in the case where the filter cover 11 is not locked (forgotten), the filter cover 11 is locked by attaching the dust collector 8, but since it is configured as described above, it is mounted. Before the dust collector 8 is used, when the filter cover 11 is securely locked by hand, the filter cover 11 can be easily inserted by pressing it in.

When the filter cover 11 is opened from the locked state as described above, the lock release button 28 is operated in a direction opposite to the locking direction X under the biasing force against the leaf spring 27. However, since the lock release button 23 is provided to operate independently in two pairs, even if only one of the buttons is operated, only one of the locked states can be released. Therefore, the operation is performed simultaneously in a manner of pinching from both sides with a finger or the like.

Then, each of the locking shaft portions 30 slides in the locking bearing receiving portion 29, and the distal end portion of the locking shaft portion 30 moves in the direction away from the locking portion 26. The locking end size of the front end portion of the locking shaft portion 30 and the locking portion 26 is a card The distal end portion of the shaft stopper portion 30 protrudes from the end portion of the locking bearing receiving portion 29 by about 3 to 5 mm. However, as described above, the operation size of the locking release button 28 is set to the front end portion of the locking shaft portion 30. The maximum size of the end portion of the locking bearing receiving portion 29 is equal to or greater than the maximum size of the end portion of the locking bearing receiving portion 29, for example, 5 mm or more, and is therefore 5 mm or more.

If the pull-up release button 28 is still pulled up from the released state, as shown in Fig. 7(b), the filter cover 11 can be easily opened at an angle of about 90 degrees toward the rear centering on the rotary shaft 32. The filter unit 23 can be taken out.

Although the locking and releasing of the filter cover 11 have been described so far, after the dust collector 8 is attached, as shown in Fig. 5, the locking release button 28 of the locking means 25 provided in the filter cover 11 is dusted. The device 8 is covered. Therefore, the jam release button 28 cannot be operated in a state where the dust collector 8 is mounted. Therefore, since the filter cover 11 is not erroneously opened in the use of the cleaner 100, the erroneous operation of the user can be prevented, and the cleaner 100 can be used safely.

Further, as described above, the filter unit 23 held by the filter cover 11 is provided so that the foreign matter does not intrude into the electric fan 21 in order to protect the electric fan 21 because the filter cover 11 holding the filter unit 23 is surely stuck. Therefore, the performance of the electric fan 21 can be prevented from being degraded or malfunctioned, and the performance of the electric fan 21 can be maintained.

Next, the holding portion 50 of the hose body 6 is placed on the filter cover 11 as shown in Fig. 12 (a) and (b). Fig. 12(a) is a side view showing a state in which the insertion piece 6g of the rigid extension tube portion 6e is inserted into the holding portion 50 of the filter cover 11 of the electric vacuum cleaner according to the embodiment of the present invention, and Fig. 12(b) A side cross-sectional view taken in the vicinity of the holding portion 50 of Fig. 12(a).

The holding portion 50 is separated from the filter cover 11 and is formed by resin molding, and is fixed to the rotating shaft 32 side (the rear side of the body 1) of the filter cover 11 with screws 51. The holding portion 50 is used to hold the hose body 6 in advance during dust collection as shown in Fig. 12(a) without being placed on the floor surface.

The holding portion 50 is as shown in Fig. 12(b), and the cross-sectional shape is The L-shaped insertion piece 6g provided in the rigid extension tube portion 6e of the hose body 6 is inserted therein. Whenever the insertion is made, the insertion piece 6g gives an impact to the holding portion 50. However, as described above, the filter cover 11 is also a component that constitutes an appearance, and when the material is selected with priority of rigidity, the appearance is impaired. Therefore, in consideration of ensuring strength, rigidity, wear resistance, and the like, the holding portion 50 is formed as another component. Moreover, in order to facilitate insertion by the user, the color of the filter cover 11 or other components and the holding portion 50 is changed as a target of the user.

In this way, even if a situation in which something else is desired to be completed occurs in a short period of time during the cleaning, it is not necessary to specifically place the hose body 6 on the floor surface, so that it is not necessary to bend or bend the knee to pick up the hose body 6, The hose body 6 can be held by hand again. Therefore, the trouble of the user picking up the hose body 6 from the floor surface can be eliminated, and the burden on the waist or knee of the user can be reduced.

In the present embodiment, the configuration in which the holding portion 50 is provided on the side of the rotating shaft 32 of the filter cover 11 (the rear side of the main body 1) will be described. However, as shown in Fig. 13(a), it may be provided in the side surface direction. The screw seat is placed in the side direction in advance, and the screw 51 is removed, and the position from the side of the rotating shaft 32 of the filter cover 11 to the side surface direction can be moved and changed. Because a screw can be removed and moved, the user can use a tool such as a screwdriver. It is also easy to move and change to a good location for your own use.

Further, the holding portion 50 is not limited to one place, and as shown in FIG. 13(b), a plurality of both of the rotating shaft 32 side and the side surface direction of the filter cover 11 may be provided by using a plurality of them. The convenience of the person is improved.

Further, in the present embodiment, the insertion piece 6g is provided in the rigid extension tube portion 6e. However, the insertion piece 6g may be provided in the suction piece 6f or the grip portion 6c, and the like, and the configuration of the hose body 6 may be provided. Any one or all of the rigid extension pipe portion 6e, the suction member 6f, or the grip portion 6c also have a similar situation in which the other thing is desired to be completed in a short period of time during the suction, and it is not necessary to intentionally place the hose body 6 on the floor surface. The hose body 6 can be held by hand again, and the trouble of the user picking up the hose body 6 from the floor surface can be eliminated.

As described above, in the embodiment of the present invention, since the filter cover 11 has the locking means 25 for locking the main body 1 and the locking release button 28 for releasing the locking state, the filter cover can be used. 11 is locked to the body 1 without elastic deformation. Since the locking means 25 is released when the lock release button 28 is operated, the filter cover 11 is not elastically deformed, and the release of the filter cover 11 is safe and easy, and the workability is improved. Moreover, the durability of the filter cover 11 for repeatedly locking and releasing can be improved by this.

Further, since the components that connect the filter cover 11 are made of other materials having high strength, rigidity, and wear resistance, the durability of the filter cover 11 when it is repeatedly opened and closed is improved. Further, since the filter cover 11 is covered by the dust collector 8 during dust collection, the filter cover 11 is not accidentally opened during dust suction, and the user's erroneous operation can be prevented, and the electric vacuum can be safely used. 100.
