Description

Technical field
The invention relates to a vacuum cleaner according to the restrictive part of paragraph 1 of the claims.
State of the art
From patent document DE 4100858 A1, a vacuum cleaner is known with a fan unit surrounded by an inner capsule, which, leaving room for air flow, is built into the outer capsule, between which and the casing there is free space. In this case, the air flow created by the fan unit is discharged through the air flow space to the outlet located in the casing. The inner cup-shaped capsule and the outer capsule surrounding it, consisting of two cup-shaped shells, completely seal the fan assembly. The inner capsule is fastened to the outer capsule by means of profiled trims molded to the outer wall of the inner capsule. The disadvantage of this attachment is that a separate assembly operation is required to attach the inner capsule to the outer one. This design not only requires a separate assembly operation, but, in addition, the walls of the air flow channel cannot be made sufficiently smooth, since the existing mounting slots form edges that interfere with the passage of the air flow.
Disclosure of invention
The objective of the invention is to create a channel for air flow (flow channel), optimized in aerodynamic terms, between the insulating capsule of the fan unit and the casing element, in a way that does not require large costs for manufacturing and assembly.
According to the invention, this problem is solved in that at least a part of the insulating capsule is combined with a casing element, in particular a fan casing, in a single part. Due to the integral connection of the insulating capsule with the fan casing, the aerodynamic characteristic of the flow channel is improved, since less mounting gaps are required, and therefore, fewer edges are formed in the flow channel that resist air flow. The possibility of errors during assembly is completely eliminated, since the position of the flow channel is precisely fixed. The assembly process itself is simplified, since there is no separate assembly operation for attaching a separate part of the capsule. In this case, the geometry of the flow channel can be improved aerodynamically, since it is not necessary to take into account the now unnecessary mounting and connecting elements.
In one preferred embodiment of the invention, the first part of the capsule is molded to the casing, in particular to the lower bowl of the vacuum cleaner. If the lower part of the capsule is already molded to the lower bowl of the vacuum cleaner body, then the fan unit can be easily inserted into the lower bowl, and you do not need to pre-mount part of the capsule on the fan unit and separately fix this pre-assembled assembly in the vacuum cleaner body. In addition, if the insulating capsule or parts thereof and / or the fan casing or parts thereof are molded directly to the housing element of the vacuum cleaner, the number of parts is reduced. Such molding can be successfully implemented by injection molding of plastic.
It is desirable that the first part of the capsule extending from the lower bowl has inwardly directed wall portions. The inward-looking portions of the capsule wall make it possible to quickly and easily insert an assembly consisting of an electric motor with a fan vertically from above into the lower bowl, which makes assembly very fast. At the same time, sound insulation of the fan unit is ensured from below and from the side of the walls of the capsule part. The surrounding fan unit with five side walls does not require mounting slots, which means that you can do without additional sealing means. Separate slots through which sound could penetrate outward are largely excluded, which ensures particularly good sound insulation.
It is desirable that at least in one portion of the capsule wall there is an opening connecting the inner space bounded by the insulating capsule to the flow channel. Moreover, in particular, if the manufacture is carried out by injection molding, the connection for the passage of air flow from the inner space of the insulating capsule into the flow channel is molded from the very beginning, so that no additional nozzles or other connecting parts need to be installed and connected to the flow channel. In addition, sealing problems disappear.
The fan casing element can be formed by half the body of the vacuum cleaner, in particular its lower bowl. It is especially desirable that not only the elements of the insulating capsule, but also the elements of the casing, such as, for example, a fan casing, are directly formed on the lower bowl or on another corresponding element of the vacuum cleaner. This further reduces the number of parts and reduces the number of separation gaps between the individual elements of the casing. Consumption for seals is reduced. And if you can refuse additional seals, then the cost of the vacuum cleaner will decrease.
In one preferred embodiment, the fan case element is equipped with a holder for a support element of the motor-fan assembly. Similarly, the holders for the motor-fan unit can be immediately formed directly on any part of the vacuum cleaner or molded to it. Preferably, this refers to a fan casing, but the holder or holders can also be formed, for example, directly on the lower bowl or on any part of the insulating capsule, or molded to them. The holder or part of the holder can also be located on the partition between the dust collector and the fan compartment.
Preferably, the holder is in the form of a cup-shaped, open on top of the protrusion protruding into the fan compartment. This allows you to easily and quickly install the motor-fan unit in the vacuum cleaner during assembly, since this only requires you to insert the motor-fan unit from above into the casing element and put the motor-fan unit on a bowl-shaped holder. This greatly simplifies assembly.
In one preferred embodiment of the invention, the fan case element is a fan case cover to which another element of the insulating capsule is molded. Along with the parts of the insulating capsule and the fan casing, preferably molded to the bottom of the vacuum cleaner, it is desirable to provide only one additional part to ensure sound insulation of the motor-fan unit in the insulating capsule in the fan compartment. Then the number of parts will be reduced to the most necessary minimum. In this case, there remains only one single dividing plane required to insert the motor-fan assembly into the cavity formed. Between these two parts there remains one single gap requiring sealing.
In this case, between the casing of the fan compartment and the second part of the capsule passes the main duct for the main air flow. The main flow channel can be located behind the side of the motor-fan unit, opposite the suction port. Between the casing of the fan compartment and the second part of the capsule may be located at least one side flow channel for secondary air flow. The position of the main flow channel allows you to direct the main air flow along the axis of the motor-fan unit in the direction of its outlet. If several secondary flow channels are provided, then their length until they are connected to the main flow channel can be the same. Due to the same length of the side flow channels, the swirl effect at each intersection of the side air stream with the main air stream is at least approximately the same. Due to the intersection of the secondary air flow with the main air flow, a particularly efficient swirl is ensured. The intersection occurs preferably in a mutually perpendicular direction of flow. However, the crossing of the main and secondary air flows can occur at other angles, for example, at an acute or even obtuse angle. Side and main air flows can even be directed towards each other.
At least one side flow channel is located on the side of the motor-fan assembly. Preferably, two side flow channels are provided extending along both sides of the motor-fan assembly. But it is possible to provide several pairs of side flow channels running along the opposite sides of the motor-fan assembly and preferably flowing into a common main flow channel. Preferably, the side flow channels have a rectangular cross section and are arranged substantially vertically. Due to this arrangement in the side flow channels, good traction is provided, and at the same time, the part of the vacuum cleaner housing in which the side flow channels are located is simple and economical to manufacture.
Thus, in one preferred embodiment, at least one side flow channel is connected through the air flow to the main flow channel through at least one inlet. The inlet can be made in the form of a circular hole in a thin partition between the secondary flow channel and the main flow channel. Due to this, a diaphragm with sharp edges is formed in the inlet area, at which an additional swirl of the exhaust air flow occurs. Moreover, the cross section of the hole in the light is preferably made smaller than the cross section of the flow in the rest of the side flow channel.
In one preferred embodiment of the invention, the cross section of the at least one inlet is smaller than the cross-section of the side flow in the corresponding channel. Due to this, a narrowing of the cross section of the flow is formed in the transition zone from the side flow channel to the main flow channel. Such a throttle can also be made in the form of a venturi. Instead of one inlet in each side flow channel, several inlets can be provided, preferably two. The sum of the cross-sections of two or more holes must nevertheless remain less than the cross-section of the side flow in the rest of the channel.
The wall portions of the first capsule element and the walls of the second capsule element are preferably overlapped. Thanks to the overlap, a guide rail is formed during the assembly process, allowing you to quickly and easily mount both elements of the capsule in the correct position. The overlapping portions of both capsule elements form a slit-like seal like a labyrinth, so that a certain sealing effect is created without the use of special sealing elements.
However, a seal can be placed between the overlapping portions of the capsule wall. Similarly, a seal can be created between the upper edge of the lower half of the fan casing, molded to the lower bowl, and the lower edge of the upper half of the fan casing. This can be a labyrinth seal, a sealing chamfer molded to one of the edges, or a sealing cord embedded in a groove formed on one of the edges.
In addition to the seal embodiments described above, additional parts of the vacuum cleaner can be molded to the part of the insulating capsule or fan casing described above. So, for example, to the casing element, in particular to the fan cap, the outlet for the exhaust air filter, the fastener for the cable drum, the cable winding zone or the slot for the slide of the regulator can be directly formed. As additional soundproofing means, fiber silencers can be placed anywhere in the flow channel.

The implementation of the invention
Figure 1 shows the lower bowl 2 of the housing 1 of the vacuum cleaner, considered as an example implementation of the invention. The lower bowl 2 is a bathtub with a flat bottom 3 and a wall 4 surrounding it along the perimeter. The wall 4 rises from the edge of the bottom 3 mainly vertically upward. A handle 5 is formed at the front end of the lower bowl 2 on the outer side of the wall 4 to the lower bowl 2. A partition 6 is located approximately in the middle between the front end 7 of the lower bowl 2 and the rear end 8 of the lower bowl 2. The partition 6 extends from that shown in FIG. .1 on the left front side of the first section 9 of the side wall to the second section 10 of the wall 4 of the lower bowl shown to the right on the rear. The partition 6 divides the lower bowl 2 into the front compartment 11 of the dust collector and the rear compartment 12 of the fan. In the partition 6 there is an inlet funnel 13 through which air is drawn in from the dust collector compartment 11 into the fan compartment 12.
In the fan compartment 12, a first capsule element 14 is molded to the lower bowl 2. The first element 14 of the capsule is formed by the wall sections 15a, 15b and 15c of the first element 14 of the capsule, part of the septum 6 and part 3a of the bottom 3, limited by the sections 15a, 15b and 15c of the wall of the first element 14 of the capsule. In the rear wall section 15b, there is an open-ended cut-out forming the first socket 16 for the first supporting element 17 shown in FIG. 3. In the side wall sections 15a and 15c, there are holes 18a and 18b forming a flow connection between the internal cavity 19 bounded by the first element 14 of the capsule, and a section 20 of the flow channel 21. The section 20 of the channel and part of the flow channel 21 are bounded laterally by sections 15a, 15b and 15c of the wall of the first element 14 of the capsule and sections 22a, 22b and 22c of the wall of the compartment 22 of the fan assembly. The side sections 22a and 22c of the wall of the compartment of the fan unit 22 are adjacent to the rear section of the wall 22b, extend in front of the partition 6 and form in the lower bowl 2 with the hermetically sealed cap of the fan compartment, which is described in more detail in figure 4, the closed compartment 22 of the fan unit. A second holding socket 24 is formed to the partition 6 under the passage opening 23, forming a protrusion 25 protruding into the fan compartment. The protrusion 25 has a cup shape and is open from above. It passes along an annular line concentrically located around the passage opening 23. A second support element 26 is inserted into the protrusion 25, which, together with the first support element 17, serves as a support for the motor-fan unit 27 shown in FIG. 2.
2, the flow direction is indicated by arrows P1-P6. The motor-fan assembly 27 is shown in a mounted position in the lower bowl 2 between the walls 15a, 15b and 15c. From the dust collector compartment 11, the air cleaned of dust by means of a filter bag or dust box (not shown) is sucked, as shown by arrows P1, through the inlet funnel 13 from the front compartment of the dust collector 11, shown in figure 2 to the right, into the rear fan compartment 12 shown in figure 2 on the left. The sucked air passes through the orifice 23 in the partition 6 and is supplied to the suction hole 28 of the motor-fan unit 27, as shown by arrow P2. The sucked air passes through the motor-fan unit 27, exits the motor-fan unit 27 from the rear side, as shown by arrows P3, and enters the inner portion 28 of the channel. In the inner portion 28 of the channel, air rushes between the wall of the casing of the motor-fan assembly 27 and the wall sections 15a and 15c of the first capsule element 14 forward to the openings 18a and 18b. After the forward-moving air passes through the openings 18a and 18b from the inner duct portion 28 to the outer duct portion 20, the flow direction changes as shown by arrows P4 and air starts to flow backward in the outer duct portion 20. In the outer duct portion 20, the air at the rear wall of the motor-fan assembly 27 rotates at a right angle, as shown by arrows P5, behind the portion 15b of the first capsule element 14. The arrows P6 shown in FIG. 2 show that at the end of the outer duct portion 20, behind the motor-fan assembly 27, the air changes direction and leaves the plane of the drawing in FIG. 2, moving further between the vertical wall portion 29a of the second capsule member 30 and the wall 31 cap 32 of the fan compartment, as shown in Fig.3.
In Fig.3 proposed in the invention a vacuum cleaner with a lower bowl 2 according to Fig.1 and 2 is shown in section. Arrows P6, which are shown in FIG. 2, as emerging from the plane of the drawing, appear in FIG. 3 in the form of an arrow P6 pointing up. Air rushes up in the direction of arrow P6 along the main flow channel 33 between the wall portion 29a of the second capsule element 30 and the fan compartment cap 32. Air moves up the main flow channel behind the motor-fan unit 27, and at the upper edge of the vertical wall section 29a changes its direction to horizontal. Now, the main flow channel 33 extends along the horizontal wall portion 29b of the second capsule element 30 under the cap 32 of the fan compartment to the outlet 34 located under the outlet filter 35. The inlet surface of the outlet filter 35 is adjacent to the outlet 34. The outlet filter 35 can trap solids, which are still contained in the air stream. Leaving the outlet surface of the exhaust filter 35, the cleaned air leaves the vacuum cleaner through a large number of exhaust openings 36 forming a plate exhaust grill.
A handle 5, a partition 6, wall sections 15 of the first element 14 of the capsule and sections 22 of the wall of the fan compartment 12 are molded to the lower bowl 2, which is a monolithic plastic part made by injection molding, The upper bowl 37 covers the fan compartment 12 and the cable chamber 38 for cable reel 39 (shown in FIG. 4). The upper outer contour of the vacuum cleaner ends with a dust collector cover 40, which is adjacent to the upper bowl 37 and extends from the rear end 41 near the outlet 36 to the front end 42. At the front end 42 there is a latch 43 that locks the dust cover 40 in the closed position with the latch 44 on the lower bowl 2. The wall 45 of the lid, formed to the lid 40 of the dust collector, surrounding the compartment 11 of the dust collector, enters the surrounding compartment 11 of the dust collector, groove 46, into which the sealing cord 47 is inserted. Groove 46 is molded to the upper edge ke molded to the lower bowl 2 of the wall 48 of the dust collector, which surrounds the compartment 11 of the dust collector. An opening 49 is provided in the dust collector lid 40 for entering dusty air, to which an unimaged suction hose fitting can be connected. On the dust collector lid 40, there is a niche 50 opening on top to accommodate accessories 54a, 54b, for example, slotted, sofa, furniture accessories or operating instructions and information sheets. The niche 50 opening from above is closed by a lid 52, reclining on a pin 51, fixed in the lid 40 of the dust collector. A removable box 53 can be inserted into the recess 51 to properly secure the accessories 54a, 54b, which is preferably blown out of a flat thermoplastic plastic sheet.
Figure 4 presents in a perspective image proposed by the invention, the cap 32 of the fan compartment. The cap 32 of the fan compartment is made in the form of a box of approximately rectangular shape. The first portion 56 of the side wall shown in FIG. 4 to the right and the second portion 57 of the side wall shown in FIG. 4 to the left and also the portion 58 of the rear wall are adjacent to the cap cover 55 at right angles. The first portion 56 of the side wall, the second portion 57 of the side wall and the portion 58 of the rear wall are interconnected by their edges, forming together a U-shaped side wall 59 of the cap 32 of the fan compartment. An outlet 34 is integrated in the lid 55. Towards the end of the lid 55, shown in front of FIG. 4, a front wall portion 29d of the second capsule member 30 is formed with a jumper 59. The front wall portion 29d of the second capsule element 30 is connected laterally to the first portion 56 and the second portion 57 of the side wall of the cap 32 of the fan compartment. The front wall section 29d is in the form of a semicircular disk and has a semicircular open notch 60 for accommodating the second supporting element 26 of the motor-fan assembly 27. Opposite the front wall section 29d is the rear vertical wall section 29a of the second capsule element 30, molded to the fan compartment cap 32. Between the rear vertical wall section 29a of the second capsule element 30 and the rear wall section 58 of the fan compartment cover 32, a main flow channel 33 extends towards the outlet 34 in the lid 55. Between the wall sections 29a and 29d, the vertical side wall sections 29b and 29c are arranged cap 32 of the fan compartment. Between the side wall portion 29c and the first side wall portion 56, a first side channel 61a extends. A second side channel 61b extends between the side wall portion 29b and the second side wall portion 57.
In Fig. 5, the first side channel 61a and the second side channel 61b are shown in sectional view of a longitudinally-mounted vacuum cleaner according to the invention. The lower bowl 2 with the formed sections 22a and 22c of the fan compartment wall 12 is shown. Inside the fan compartment 12, sections 15a and 15c are formed to the bottom 3. the walls of the first element 14 of the capsule. The first side channel 61a is bounded by a wall portion 22a and a wall portion 15a. As arrows P8 show, the first side air flow moves upstream in the side channel 61a between the wall portion 29c and the first side wall portion 56 of the fan compartment cap 32, and the second side air flow moves up the side duct 61a between the wall portion 29b and the second side portion 57 the walls of the cap 32 of the fan compartment. A groove 63 for sealing is formed on the lower edge 62 of the side wall portions 56 and 57 and the rear wall portion 58 (not shown). The upper annular edge 64 of the wall sections 22a, 22b and 22c enters the groove. Alternatively, an unshown sealing cord may be inserted in the groove. A seal 63 closes the connector between the cap 32 of the fan compartment and the fan compartment 12. Another seal 65 is provided between the first capsule member 14 and the second capsule member 30. The seal 65 is designed as a labyrinth seal. For this, the wall sections 15a, 15b and 15c of the wall of the first capsule element 14 partially overlap the wall sections 29a, 29b and 29c of the wall of the second capsule element 30.
The side air flows directed vertically upward along the arrows P8 are poured through the openings 66 into the main flow channel 33. Moreover, as shown by the arrows P9, the side air flows are directed perpendicular to the main air flow. Arrow P7, which in FIG. 3 is directed from left to right, in FIG. 5 is depicted in the form of arrow P7 emerging from the plane of the drawing. Due to the collision of the side air flows P9 and the main air flows P7 at a right angle, air swirls and dissipates and enters the outlet 34, as shown by arrow P10. Above the outlet 34, there is an exhaust filter 35 inserted into the holder 67 (FIG. 4), molded to the cap 32 of the fan compartment. The holder has an annular ledge 68 with a seal 68 molded to it, on which the exhaust filter 35 lies. As shown in FIG. 4, not only the holder 67, but also the cable channel 70 is formed as a fixed element to the hood cover 32.
