Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a vacuum cleaner with a storage case in which a main body case is placed in a storage case that stores 11F parts such as a suction hose and a mouthpiece of the vacuum cleaner. This is related to the improvement of.

[Prior art]

This type of vacuum cleaner was not intended to be used while the vacuum cleaner was placed in the storage case.

[Purpose of the invention]

The present invention aims to reduce exhaust noise in vacuum cleaners that are used while placed in a storage case.

[Summary of the invention]

In the present invention, the main case is constructed by combining an upper case and a lower case vertically, and the inside of the main case is divided into a dust case section on the front side and a motor storage section on the rear side, and an exhaust port is provided on the rear wall of the lower case. The storage case is provided with a raised part that covers the lower part of the exhaust port when the main body case is placed on the storage case button, and a gap for ventilation is provided between this raised part and the exhaust port. It is characterized by:

〔Effect of the invention〕

According to this configuration, the following effects can be expected.

(1) Air is exhausted directly from the upper side of the exhaust port. Exhaust gas discharged from the lower side of the exhaust port collides with the rising portion and flows into the storage case through the ventilation gap, thereby reducing exhaust noise.

(2) Since the exhaust from the upper side is directly exhausted, the exhaust performance is better than when all the exhaust is exhausted into the storage case.

(3) If the vacuum cleaner body and storage case are combined and used in an upright position with the exhaust port facing down, the lower part of the exhaust port will be blocked by the floor surface due to the raised part. Not possible. Therefore, you can use a vacuum cleaner.

(4) If you put a cleaning rag in the storage case, the heat from the exhaust air will dry the rag.

Example Hereinafter, actual examples of the present invention will be explained with reference to the drawings.

This vacuum cleaner has a flat shape.

It has a safe shape with a short length and wide width, and is excellent in terms of running performance. Main case 1 consists of upper case 2 and lower case 3.
are formed by combining.

Large wheels 4 are attached to both rear sides of the lower case 3. The wheels 4 are mounted so that the outer periphery of the wheels 4 extends slightly beyond the rear surface of the main body case 1. Further, small wheels 5 are provided on the bottom surface of the lower case 3 closer to the front. This wheel 5 is attached to a wheel support stand 6. The wheel support stand 6 is rotatably attached to the boss portion 7 of the lower case 3.

The wheel support stand 6 has a spherical lower surface. Since it is spherical, it acts like a sled when climbing over a threshold.

The interior of the main body case 1 can be roughly divided into two parts. The front side is the dust case part, and the back side is the electric blower storage part. An electric blower 8 is placed inside the electric blower housing. A cord reel (not shown) is also placed.

The plug 9 of the power cord wound around the cord reel is the third
As shown in the figure, the cord is inserted into the cord insertion/extraction opening 10. Cord insertion/extraction eye 1 (1: provided on the rear wall 11 of the upper case 2.The rear wall 11 is inclined.Furthermore, there are feet 12 on the rear wall 11 for using the main case in an upright position. It is formed in one piece.

A stopper operation button 13 for the cord reel is provided on the rear upper surface of the upper case 2.

Rear wall portion 14 of lower case 3 or vertical slint-shaped exhaust port 15
is provided.

At the center of the upper surface of the upper case 2 is a carry handle 1.
6 is installed. This handle 16 is the support shaft 1
7 and is rotatably supported.

The support shaft 17 is located almost directly above the weight of the main body case 1. Therefore, you can carry the vacuum cleaner by laying it horizontally. It's easy to hold.

A dust case 18 having an open top is removably attached to the dust case portion of the main body case 1. This dust case 18 has a lower surface and all side surfaces formed of a dust collecting filter. A bag-shaped paper filter 191-J housed in the dust case 18: When it is full of garbage, it is thrown away together with the garbage.

An outer cover 20 that can be opened and closed is provided on the upper part of the dust case section. This outer cover 20 is rotatably supported by the support shaft 17. The outer cover 20 is opened by lifting the front side, and as shown in FIG. 8, the outer cover 20 is opened to remove the paper filter 19 and replace the paper filter 19 with a new one. Further, the dust case 18 can be removed with the paper filter 19 still inside.

An airtight backing 21 is placed in the upper part of the dust case 18.
is installed. The filter support plate 22 is provided so as to close about half of the opening of the dust case 18. Since the rear side of the filter support plate 22 is rotatably supported by the support pins 23, the paper filter 19 can be easily removed. That is, the outer lid 20
When the paper filter 19 is opened and the paper filter 19 is lifted, the filter support plate 22 is opened to the rear using the support bin 23 as a fulcrum. And the paper filter 19 is the dust case 18
extracted from. If the filter support plate 22 is located on the front side of the dust case 18, it will open toward the front, and the filter support plate 22 will get in the way when the paper filter 19 is removed. The filter support plate 22 is provided on the rear side in order to facilitate the removal of the paper filter 19.

The mouth plate 24 of the paper filter 19 is supported so as to straddle the filter support plate 22 and the opening edge of the dust case 18, as shown in FIG. In this way, the paper filter 19 is attached to the dust case 18. Since the filter support plate 22 is provided, the mouth plate 24 only needs to be that small. Since the opening plate is made from 24 sheets of thick banknotes, it is particularly desirable that it be small in order to reduce material costs.

Since the pre-wash filter support plate 22 is provided on the rear side,
It has been mentioned that the paper filter 19 is easy to remove.

It is also good for defeating paper filter 19.

A hose connection port 25 is provided on the front surface of the outer lid 20. The hose connection port 2'5 is connected to the discharge port 26. The discharge port 26 is adapted to fit into the inlet of a mouth plate 24 provided on the paper filter 19 when the outer lid 2o is closed.

27 are provided. This paper filter storage chamber is provided with a lid 28 that can be opened and closed. The rear side of the lid 28 is rotatably supported by a support shaft 29.

The spare paper filter 19 is attached to the lid 28 as shown in FIG.
Open it to put in and take out. When the outer cover 20 is opened, it is stopped at a point where it is slightly tilted toward the rear as shown in FIG. 8, so that it is particularly easy to insert and remove the spare paper filter 19.

An engagement recess 30 for clamping is formed at the lower front side of the outer lid 20. A clamp 31 is attached to the lower front side of the upper case 2. The clamp 31 engages and disengages from the engagement recess 3° of the engagement claw 33 of the clamp 31, which is rotatably mounted with the pin 32. Spring 3 of clamp 31
4 has the function of urging the engagement claw 33 to engage with the engagement recess 30.

When the clamp 31 is pushed downward against the spring 34, the clamp 31 rotates around the pin 32 as a support shaft. Then, the engagement claw 33 is removed from the engagement recess 30. The outer cover 20 is automatically opened as shown in FIG. 8 by the force of a spring (not shown) provided at the support shaft 17.

A starting handle 35 is provided on the front side of the lower case 3 for use when setting up the vacuum cleaner body. The lower part 36 of the clamp 31 is located inside this handle 35. When holding the handle 35 to stand up the vacuum cleaner body, the fingers of the hand holding the handle 35 come to press down on the descending part 36. When the descending portion 36 is pressed, the engaging claw 33 of the clamp 31 is further pressed against the engaging recess 30, and there is no possibility that the outer i20 will open by any chance.

The front side of the lower case 3 is greatly recessed as if a wide area corresponding to the rear side of the handle 35 has been folded.

An engagement recess 37 for a clamp to be connected to the main body storage case, which will be described later, is provided in this recess.

Further, the rear part of the case 3 is stepped down below the exhaust port 15. An engaging protrusion 38 is provided at this depressed position.

The above is the explanation about the vacuum cleaner main body.

Next, the storage case 39 will be explained. Also clarify the relationship with the vacuum cleaner itself.

As shown in Fig. 4, there are 39 storage cases, in which accessories such as a suction hose and suction mouth are placed, and on top of which the main body of the vacuum cleaner is placed.

The storage case 39 has four wheels on the bottom, so
You can easily move the vacuum cleaner on the floor with the vacuum cleaner body on it.

The upper opening edge of the storage case 39 is flat. The front side is concave inward. The clamp 40 has a recess 41
is attached to the top of the Engagement hole 4 on the upper part of the rear side
2 is provided. Wheel storage portions 43 projecting outward are provided on the rear sides of both sides. Also, the rear side has engagement hole 4
A slightly raised part has a shelf part 43 extending outward and a rising part 44 rising upward from this part.

The clamp 40 is rotatably supported by a support shaft 45 and is provided with a spring (not shown). An engaging pawl 46 is provided at the upper end of the clamp 40.

The attachment of the vacuum cleaner main body to the storage case 39 is carried out as follows 7.

The retaining protrusion 38 provided on the rear surface of the lower case 3 constituting the main body case 1 is fitted into the engagement hole 42 provided on the rear side of the storage case 39, and the front side of the main body case 1 is attached to the storage case 39. By fitting K into the clamp 40 , the engaging claw 46 of the clamp 40 engages with the engaging recess 37 provided in the lower case 3 of the main body case 1 . In this way, the vacuum cleaner body placed on the storage case 39 is coupled to the storage case 39 as shown in FIG.

This vacuum cleaner can be used even when it is placed in the storage case 39. I will discuss this in detail.

Since the cord insertion/extraction opening 10 for the power cord plug 9 is provided on the upper case 2 side, which constitutes the entire body area 1, there is no problem in inserting and removing the plug 9. Also, the suction port can be attached to and removed from the cord connection port 25. Since the clamp 31 is also exposed outside the storage case 39, the outer cover 20 can be opened by operating the clamp 31. It is also possible to replace the paper filter 19 and remove the dust case 18.

The fact that this vacuum cleaner can be used while being placed in the storage case 39 has the following advantages.

(1) As mentioned earlier, this vacuum cleaner is flat and short. If it is not placed in the storage case 39, the hose connection port 2
The height up to 5 (as shown in Figure 7) is 1+L. However, when placed on the storage case 39, the storage case 39
Therefore, the total height up to the hose connection port 25 becomes h2. It is convenient for cleaning high places such as lintels, lampshades, ceilings, and high walls.

Note that when used after being removed from the storage case 39, it is a flat vacuum cleaner, so it is extremely stable.

(2) When moving between steps such as thresholds or moving from room to room, use the carrying handle 16.
'fc and carry the main body of the vacuum cleaner along with the storage case 39. Since the position of the no-endoru 16 is higher by the amount of ho, the amount of bending at the waist is reduced accordingly.
Easy to carry. Although it seems that the weight of the storage case 39 makes it difficult to carry, the storage case 39 is light compared to its external size, so it is not difficult to carry.

(3) Also, since the main body of the vacuum cleaner is placed high by the amount of ho, the paper filter 19 etc. can be easily replaced.

That is, operate the clamp 31 to fully open the outer lid 20, remove the paper filter 19 that is full of dust, open the lid 28, and remove the spare paper filter 19 that has fallen out from the paper filter storage chamber 27. Attach to case 28. Further, if necessary, the dust case 28 is taken out and the fine dust accumulated in the dust case 28 is thrown away. This kind of work is easy to do because the vacuum cleaner itself is placed high, so you don't have to bend over much.

(4) Since this vacuum cleaner can be disposed of along with the paper filter 19, garbage disposal is sanitary and easy. In addition to this, spare paper filter 19
It has the advantage of being usable even when you don't have one. That is,
When the paper filter 19 is not used, dust accumulates in the dust case 28. Garbage disposal is performed by removing the dust case 28. If there is no dust case 28, the vacuum cleaner body must be carried around.

In comparison, garbage disposal is easier because it only requires carrying the dust case 28.

(5) Although this flat vacuum cleaner has the advantage of being able to run stably, it is unstable when used in an upright position. That is, as shown in FIG. 9, the vacuum cleaner body can be used standing alone. This is how you clean high places. The vacuum cleaner body stands with the feet 12 and wheels 4 in contact with the floor. Although the height is h3, the length of the ground contact portion is small, Ll, so it is very unstable.

However, if the vacuum cleaner body is used in an upright position while attached to the storage case 39, the instability is resolved. That is, hold the handle 35 for standing up and stand the vacuum cleaner body together with the storage case 39 as shown in FIG. The vacuum cleaner body stands in a state in which the foot part 12 and a part of the rear side of the storage case 39 are in contact with the floor surface and combined with the storage case 39. Since the length of the grounding part is L2, it is longer than Ll when the vacuum cleaner body is stood alone, making it more stable.

Since the weight W of the storage case 39 is applied downward, stability is increased. Furthermore, even if the storage case 39 is tilted toward the storage case 39 side, the corner D of the storage case 39 serves as a support, which effectively works to prevent the storage case 39 from falling over.

The increased stability makes it easier to clean high places and to replace the paper filter 19.

:6) When the main body of the vacuum cleaner is used in the storage case 39, the exhaust will be as shown in FIG. 11.

That is, the stand-up portion 44 provided at the rear of the storage case 39 covers only the lower half of the exhaust port 15 provided in the lower case 3 of the main body case 1. Exhaust port 15
Of the total height ttl, only t2 is covered, but exhaust port 1
A gap d2 is provided between the outer surface of 5 and the rising portion 44. Since there is also a gap between the rear corner of the lower case 3 below the exhaust port 15 and a part of the storage case 39 facing thereto, the exhaust gas discharged from the exhaust port 15 is divided. Whereas the upper exhaust V flows straight out,
The lower exhaust gas collides with the rising portion 44 and enters the storage case 39 through the gap. The exhaust gas flowing into the storage case 39 can be significantly silenced, similar to the exhaust gas flowing into the large exhaust chamber. In addition, since the rising portion 44 covers only about half of the exhaust port 15,
The exhaust gas from the upper side flows straight out, and the exhaust performance is not affected by light pollution.

In other words, both noise reduction and exhaust performance are guaranteed. In addition, due to the exhaust heat flowing into the storage case 39, the inside of the storage case 39 can be used as a drying room. In other words, when using a vacuum cleaner, people often use a rag at the same time. If you put a rag in the storage case 39, you can dry it. This vacuum cleaner uses a paper filter 19 and a dust collection filter in the dust case 18 (both filters have fine filtration meshes) to trap fine dust in two stages, reducing the amount of fine dust blowing through during drying. It is rare for the rag to get dirty with exhaust gas.

In addition, Figure 11 cited in this exhaust and Figure 6 explained earlier
It seems that the configuration does not match the diagram, but this is because the cross-sectional locations in the diagram are different. That is, the right side cutaway illustration in FIG. 6 shows the vacuum cleaner main body and the storage case 39 in cross section at the center. Here, the rear bottom corner S of the lower case 3 constituting the main body case 1 is in contact with the shelf portion 43 of the storage case 39. This contacting portion is approximately 1/& of the total width of the exhaust port 15. As shown in FIG. 11, the remaining two-thirds is a gap between the rear bottom corner of the lower case 3 and the main housing case 39 facing thereto.

(When used vertically as shown in Figure 10, exhaust is often carried out. In other words, even when placed on a soft surface such as a carpet, the exhaust port 15 Even if the upper half is closed, the lower half has the rising portion 44, so the gap d2 is still maintained and the exhaust gas flows into the storage case 39. The exhaust function is not impaired.

(8) As shown in FIG. 6, the clamp 40 is sunk into a recess 41 provided on the front side of the storage case 39. While cleaning and transporting,
Even if the front side of the storage case 39 collides with a chair, kotatsu, etc., the clamp 40 will not be pushed, so the engaging claw 4 of the clamp 40
6 does not come off from the engagement recess 37 provided in the lower case 3 of the main body case 1. Since the depth of the recess 41 is about 7 Crn, the distance d between the nozzle 35 and the clamp 40 is
is approximately 7 cm. Since there is a clamp 40 even if it falls to this extent, it is unlikely that anything will hit this handle. The clamp 40 may come off during cleaning or transportation, and the vacuum cleaner body and storage case 3 may come off.
91-1, so you can clean and carry it with confidence. Furthermore, since the clamp 40 does not protrude beyond the handle 35, the overall size of the product can be reduced accordingly.
