Description
Technical Field
The present invention relates to the field of suction nozzles for vacuum cleaners (vacuum cleaners). In particular, the invention relates to a suction nozzle comprising a pivotably arranged edge.
Background
The vacuum cleaner is the following device: the device uses the suction force generated by the fan or motor unit to create a specific vacuum or negative pressure (unrefrissure) to draw items such as dust, particles, fibers, hair, etc. from surfaces such as floors and carpets. Typically, this is done by means of a vacuum cleaner nozzle which is connected via a nozzle outlet to an extension tube and/or suction hose and to a dust collection chamber, in which dust can be separated from the dust-laden air stream.
Various efforts have been made to improve the performance of the suction nozzle (e.g. dust pick-up capability) and to meet energy efficiency requirements and energy labels, and also to facilitate the use of vacuum cleaners. The dust suction of the vacuum cleaner can be determined, for example, by the air flow and the negative pressure at the suction nozzle. However, since the negative pressure is associated with the movement resistance of the suction nozzle and the air flow is associated with the energy consumption of the motor unit, a balance between those parameters is required.
An example of a cleaning head for a vacuum cleaner is disclosed in US20170231449, which comprises a pivotally arranged rim adapted to pivot between a retracted position and a deployed position.
Although suction nozzles for vacuum cleaners are known, there is a need for improved vacuum cleaner suction nozzles which are more user friendly and which are more flexible in terms of various types of surfaces, movement resistance and/or dust pick-up characteristics.
Disclosure of Invention
To better address one or more of the above problems, a nozzle for a vacuum cleaner is provided with the features defined in the independent claims. Preferred embodiments are defined in the dependent claims. Thus, according to a first aspect, a nozzle for a vacuum cleaner is provided.
During operation of the suction nozzle, i.e. during vacuum cleaning (vacuuming) of a surface, such as a floor or carpet, the suction nozzle may be pushed and pulled over the surface in a reciprocating motion in which, for example, the underside of the suction plate of the suction nozzle, i.e. the side or part thereof where the suction opening of the suction nozzle is located, may be arranged substantially horizontally or parallel to the surface.
The suction nozzle comprises an inlet portion comprising a suction opening, i.e. an inlet opening to the inlet portion, the suction opening having a suction area at least defined by a first edge. In other words, the suction zone is limited at least by the first edge and by the other edges defining the suction opening. Furthermore, the first edge is arranged to pivot about the first axis, which means that the first edge can rotate about the first axis and thereby change the angular position of the first edge relative to the suction plate. The first edge is arranged to pivot between a retracted position and a deployed position. The retracted position of the first edge means that the first edge is arranged substantially parallel or substantially in the same plane as the suction plate. The extended position of the first edge means that the first edge has been rotated about the first axis from the retracted position in a direction from the suction plate towards the surface to be cleaned. Thereby, during use of the suction nozzle, an angle is formed between the first edge and the suction plate and between the first edge and the surface to be cleaned.
Furthermore, the first edge is arranged to reduce the suction area of the suction opening in the deployed position of the first edge. The position of the first edge influences the size of the suction zone, which can be reduced at least by the first edge. The size of the suction zone can thus be adjusted by changing the position of the first edge, more particularly by pivoting, i.e. by rotating the first edge about the first axis. Thus, the first edge is arranged such that the size of the suction area is reduced, i.e. the suction area is reduced when the first edge is positioned in the deployed position.
The negative pressure generated by the vacuum cleaner at the suction nozzle depends on the size of the suction area of the suction nozzle. Thus, the larger the suction area, the higher the negative pressure and thus the greater the suction force acting on the suction nozzle, which suction force is linked to the resistance of the suction nozzle to movement against the surface to be cleaned.
Thus, by influencing the suction area, the suction force and thus the movement resistance can be controlled and regulated in a simple and efficient manner. Thus, by changing the position of the first edge and by positioning the first edge in the deployed position, the resistance to movement can be reduced and by the user moving it over the surface to be cleaned, a smoother movement of the suction nozzle can be achieved.
Thus, an improved suction nozzle for a vacuum cleaner is provided, as a result of which the above-mentioned object is achieved.
Further, the inlet portion may comprise a front portion and a rear portion, wherein the first edge may be arranged at the front portion of the inlet portion, or the first edge may be arranged at the rear portion of the inlet portion.
The front part refers to a part of the inlet part which is related to the placement of the suction nozzle (e.g. relative to the suction opening) in connection with the forward movement of the suction nozzle during vacuum cleaning of a surface, in front of and in front of the suction opening. In a similar manner, the rear part refers to a part of the inlet part which is located behind and behind the suction opening when the suction nozzle is moved forward during vacuum cleaning of the surface. Thus, by arranging the first edge at the front portion of the inlet portion, the movement resistance can be controlled and adjusted during movement of the suction nozzle in the forward direction. In a similar manner, by arranging the first edge at the rear part of the inlet portion, the movement resistance can be controlled and regulated during the movement of the suction nozzle in the backward direction.
Alternatively, the first edge may comprise a first lip arranged to abut the surface to be cleaned in the retracted position of the first edge and a second lip arranged to abut the surface to be cleaned in the extended position of the first edge. Lip means a protrusion. Thus, the first lip is arranged to abut the surface to be cleaned in the retracted position of the first edge, i.e. to be in contact with the surface to be cleaned in the retracted position of the first edge. The second lip is arranged to abut, i.e. to be in contact with, the surface to be cleaned in the deployed position of the first edge. Thus, in the retracted and deployed positions of the first edge, the first edge may contact the surface to be cleaned through the lip and/or through the second lip. The shape of the first lip may be different from the shape of the second lip. The difference in shape of the first lip and the second lip may result in different characteristics and properties of the suction nozzle when the first lip through the first edge or the second lip through the first edge abuts the surface to be cleaned. Thereby, different characteristics of the suction nozzle (e.g. related to the movement resistance or friction of the suction nozzle) can be achieved in the retracted and the extended position of the first edge.
Depending on the surface to be cleaned, the first lip may run smoothly along the surface in the retracted position of the first edge, or may cause a resistance acting on the first lip which may cause pivoting, i.e. rotation of the first edge about the first axis, during vacuum cleaning of the surface. As a result, the first edge may pivot about the first axis when the resistance acting on the first lip exceeds a threshold.
Accordingly, an improved suction nozzle for a vacuum cleaner is provided which can be changed, i.e. the characteristics of the suction nozzle modified, during use by positioning the first edge in a retracted position or in an extended position.
Alternatively, the second lip may comprise a rounded portion for abutting the surface to be cleaned in the deployed position of the first edge. The rounded portion is thus arranged to abut the surface to be cleaned in the unfolded position of the first edge, i.e. the rounded portion is arranged to be in contact with the surface to be cleaned in the unfolded position of the first edge. Rounded means that it is curved or in other words that it does not have any sharp corners. Thereby, the rounded portion of the first edge is arranged to minimize drag and friction between the first edge and the surface to be cleaned, and thereby to achieve a smooth movement of the suction nozzle in the deployed position of the first edge.
Accordingly, an improved suction nozzle for a vacuum cleaner is provided which can be changed, i.e. the characteristics of the suction nozzle modified, during use by positioning the first edge in a retracted position or in an extended position. Furthermore, a smoother movement of the suction nozzle in the deployed position of the first edge can be achieved by the rounded portion.
Alternatively, in the deployed position of the first edge, at least the suction area of the suction opening can be reduced by the lip. The lip is arranged such that it in the deployed position of the first edge faces, i.e. protrudes into, the suction opening. In the unfolded position of the first edge, the suction opening and the suction area can thereby be reduced in a simple and effective manner at least by the lip.
The first edge may be arranged to lift the suction nozzle from the surface to be cleaned in the deployed position of the first edge. In this way, in the deployed position of the first edge, the distance between the suction nozzle or at least a part of the suction nozzle, in particular the underside of the suction plate of the suction nozzle, and the surface to be cleaned can be increased.
According to an embodiment, the first axis may be arranged eccentrically with respect to the first edge. Decentering refers to displacement of the first axis relative to the center of rotation of the first edge. Because the first axis may be arranged eccentrically with respect to the first edge, a larger radius rotation of the first edge may be achieved. By a larger radius rotation of the first edge, a better control of the pivoting effect of the first edge can be achieved. These effects relate to, for example, reducing the suction area and lifting the suction nozzle to achieve: the movement resistance is reduced; to enable the suction nozzle to move more smoothly on the area to be cleaned; at least reducing the impact of the nozzle jumping over the surface to be cleaned or the nozzle sinking into, for example, a carpet being vacuumed.
Alternatively, the first edge may be biased in the retracted position. Thus, in the retracted position, a spring force may act on the first edge, holding the first edge in the retracted position, and preventing the first edge from pivoting in an uncontrolled manner from the retracted position. In other words, improved control of the rotational movement of the first edge about the first axis between the retracted position and the extended position may be achieved.
According to an embodiment, the first edge may be arranged to be locked in the retracted position or the extended position by a locking mechanism (e.g. a locking pin activated by a button or a slider). Thus, the first edge may be fixed in a retracted position or in a deployed position, so as to be maintained in the retracted position or in the deployed position during movement of the suction nozzle along a surface (which may be a floor). Thus, a user may lock the first edge in the retracted position or the extended position by the locking mechanism.
Further, the first edge may return from the deployed position to the retracted position when changing the direction of movement of the suction nozzle and if the first edge has not been locked in the retracted position or the deployed position.
The first edge may be arranged to pivot into the deployed position during movement of the suction nozzle in the first direction. The first direction may correspond to a forward movement of the suction nozzle, which results in that the first edge may be pivoted into the deployed position during the forward movement of the suction nozzle during vacuum cleaning of the surface.
The first edge may be arranged to automatically pivot into the deployed position. By "automatic" is meant an action that does not require the user to pivot the first edge into the deployed position. The first edge may thus automatically pivot into the deployed position, for example, when a resistance or friction force acting on the first edge exceeds a threshold value. Furthermore, the first edge can also be pivoted into the deployed position by a suction/vacuum force formed at the suction nozzle and when the suction/vacuum force exceeds a threshold value. The first edge can thus be pivoted into the deployed position simply by a resistance or friction force acting on the first edge or by a suction/vacuum force at the suction nozzle. Thus, an improved suction nozzle is provided which may facilitate the use of the vacuum cleaner.
According to an embodiment, the first edge may be arranged to pivot into the deployed position by interaction of the first lip with a surface to be cleaned (e.g. a carpet or carpet). The first lip (which may also be referred to as a first protrusion) is arranged to protrude from the first edge and contact the surface in the retracted position. Because the first lip protrudes from the first edge, the first lip may protrude into the surface to be cleaned during the movement of the suction nozzle and thereby cause a friction force acting on the first edge.
The friction generated by the interaction of the first edge with the surface may cause the first edge to pivot from the retracted position to the deployed position.
According to an embodiment, the suction nozzle may comprise a second edge arranged to pivot about a second axis, wherein the suction area is then defined by at least a first edge and a second edge, wherein the second edge is arranged to pivot between a deployed position and a retracted position, and wherein the second edge is arranged to reduce the suction area of the suction opening in the retracted position of the second edge, wherein the second edge is arranged at an opposite portion of the inlet portion with respect to the first edge. The second edge may be arranged in a similar manner as the first edge, i.e. the second edge may comprise a lip and a rounded portion having a function and effect with respect to the first edge. The second edge may be arranged to pivot into the deployed position during movement of the suction nozzle in a second direction opposite to the first direction. The second direction may correspond to a backward movement of the nozzle during vacuum cleaning of the surface.
The suction nozzle may further comprise an outlet portion having an outlet (the outlet being adapted to be coupled to a hose of the vacuum cleaner), an air channel between the suction opening and the outlet, and a housing arranged to enclose the air channel.
According to a second aspect, there is provided a vacuum cleaner comprising a suction nozzle according to the first aspect described above. Accordingly, an improved vacuum cleaner is provided.
Other features and advantages of the present invention will become apparent when studying the appended claims and the following detailed description. Those skilled in the art will recognize that the various features described can be combined to form embodiments other than those described below without departing from the scope of the invention, which is defined by the appended claims.

Detailed Description
Embodiments herein will now be described more fully with reference to the accompanying drawings, in which example embodiments are shown. Features disclosed in the exemplary embodiments may be combined. Like numbers refer to like elements throughout. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
Figure 1a shows a suction nozzle 1 for a vacuum cleaner, the suction nozzle 1 comprising an inlet portion 3 with a suction opening 5. Furthermore, the suction nozzle comprises a first edge 7, the first edge 7 being arranged to pivot about a first axis 9. The first axis 9 is shown in more detail in fig. 2. In fig. 1a, a joint between the first edge 7 of the suction nozzle and the inlet portion 3 is shown, which joint is located at the axis 9. The joint may include a seal.
The inlet portion 3 comprises a front portion 11 and a rear portion 13. As shown in fig. 1a, the first edge 7 is arranged at the front portion 11 of the inlet portion 3 of the suction nozzle 1. However, the first edge may be arranged at the rear portion 13. The nozzle 1 is shown during its movement in a first direction p1, which movement in the first direction p1 may be a forward movement of the nozzle during vacuum cleaning of a surface S, such as a floor. Thus, the suction nozzle can be used for cleaning floors.
According to the embodiment shown in fig. 1a and 1b, the first edge 7 comprises a first lip 15 and a second lip, wherein the second lip comprises a rounded portion 17. Thus, the first edge 7 comprises different parts having different shapes, resulting in different characteristics of the suction nozzle when the different parts of the first edge 7 abut the surface to be cleaned. In this way, the characteristics of the suction nozzle can be changed and controlled simply by changing the portion of the first edge that adjoins the surface to be cleaned. The first lip 15 may be sharp or may be rounded, i.e. curved. In a side view of the first edge 7, the rounded portion 17 may for example have a cut-out shape or a circular shape. The first lip 15 is arranged to abut the surface S to be cleaned in the retracted position of the first edge 7 (as shown in fig. 1 b), and the rounded portion 17 is arranged to abut the surface S in the extended position of the first edge 7. In fig. 1a, the first edge 7 is positioned in the deployed position, which occurs during movement of the suction nozzle in the first direction p 1.
The first edge 7 is arranged to pivot between a retracted position and a deployed position. As can be observed in fig. 2, in the deployed position of the first edge 7, the suction area a has been reduced by the first lip.
The first edge 7 is arranged to lift the suction nozzle 1 from the surface S to be cleaned in the deployed position of the first edge 7. In this way, in the deployed position of the first edge, the distance between the suction nozzle or at least a part of the suction nozzle 1, in particular the underside 2 of the suction plate of the suction nozzle, and the surface to be cleaned can be increased. With the first edge 7 in the deployed position, the front portion 11 of the inlet portion 3 of the suction nozzle 1 is lifted. As shown, in the unfolded position of the first edge 7, an angle α is formed between the underside 2 of the suction plate and the surface S. Depending on the size of the first edge 7, i.e. the maximum distance between the place of the first axis 9 at the first edge 7 and the outermost point at the first edge 7, and depending on the positioning of the retracted position and the extended position, the angle α may vary between e.g. 0 ° and 10 °.
The first axis 9 is arranged eccentrically with respect to the first edge 7. Decentering means that the first axis 9 is displaced relative to the centre of rotation of the first edge.
Furthermore, the suction nozzle 1 comprises an outlet portion having an outlet 23, the outlet 23 being adapted to be coupled to a hose of a vacuum cleaner. An example of a vacuum cleaner is shown in figure 5. The suction nozzle 1 further comprises an air channel (not shown) between the suction opening 5 and the outlet 23, and a housing 25 arranged to enclose said air channel.
In fig. 1b a suction nozzle 1 is shown comprising a first edge 7 and a second edge 19. The second edge 19 is arranged to pivot about a second axis 21, wherein the suction area is defined by at least the first edge 7 and the second edge 19, wherein the second edge 19 is arranged to pivot between a deployed position and a retracted position in a similar manner to the first edge described above, and is arranged to reduce the suction area of the suction opening 5 in the deployed position of the second edge 19. The second edge 19 is arranged at an opposite part of the inlet portion 3 with respect to the first edge 7. The second edge 19 may be arranged in a similar manner to the first edge 7, i.e. the second edge 19 may comprise a second lip and a second rounded portion arranged in a similar manner to the lip and rounded portion at the first edge described above.
In fig. 1b, the second edge 19 is arranged at the rear portion 13 of the inlet portion 3. In fig. 1b, the first edge 7 is positioned in the retracted position and the second edge 19 is positioned in the extended position, which occurs during movement of the suction nozzle in the second direction p 2. The second direction p2 may be a backward movement of the suction nozzle 1. With the second edge 19 in the deployed position, the rear portion 13 of the inlet portion 3 of the suction nozzle 1 is lifted. As shown in fig. 1b, the suction nozzle 1 has been lifted by the second edge 19 in the deployed position and an angle β is formed between the underside of the suction plate and the surface S. Depending on the size of the second edge 19, i.e. on the size of the first edge 7, i.e. on the maximum distance between the place of the second axis 21 and the outermost point at the second edge 19, and depending on the positioning of the retracted position and the extended position, the angle β may vary between, for example, 0 ° and 10 °.
The suction nozzle 1 may be made of a plastic material. The first edge 7 and the second edge 19 may be made of a plastic material or metal, such as for example aluminium.
According to an embodiment, the first edge 7 may be arranged to be locked in the retracted or the extended position by a locking mechanism (not shown) which may be locked by a button or a slider activated locking pin. Thus, the first edge 7 may be fixed in a retracted position or in an extended position.
As shown in fig. 1a and 1b, the suction nozzle 1 may be arranged within a housing 31. Thus, according to an embodiment, the housing 31 is arranged such that the housing encloses the suction nozzle 1. Thereby, the protective nozzle 1 is protected from possible impacts during use of the nozzle 1, i.e. during vacuum cleaning. The housing 31 may be attached to the suction nozzle 1 by attachment means arranged in a usual manner and therefore not described in detail herein.
In fig. 1a an embodiment is shown, wherein the suction nozzle 1 comprises a first edge 7. The housing 31 can thus be adapted to the suction nozzle 1 comprising the first edge 7 by, for example, designing the housing 31. Alternatively, the housing 31 may be adapted to the suction nozzle 1 comprising the first edge 7 and the second edge 19, as shown in fig. 1b, by e.g. designing the housing 31.
The housing 31 may be made of a plastic material or any other material suitable for the housing 31 of the nozzle 1 for a vacuum cleaner.
In fig. 2a and 2b, a top view of the inlet portion of the suction nozzle of fig. 1a is shown, the first edge 7 being in a retracted position in fig. 2a and in an extended position in fig. 2 b. The suction zone is denoted a in the retracted position and B in the deployed position. As can be observed, the suction zone has been reduced by the first edge 7 in the deployed position, since the area B of the suction zone is smaller than the area a of the suction zone in the retracted position of the first edge 7. The suction area may be reduced by, for example, 5% to 10% from the area at the retracted position of the first edge 7 (area a) to the area at the extended position of the first edge 7 (area B).
In fig. 3, a graph is shown representing a function "f" representing the relationship between the movement resistance and the size of the suction area. The negative pressure generated by the vacuum cleaner at the suction nozzle depends on the size of the suction area of the suction nozzle, so that the larger the suction area, the higher the negative pressure, thereby acting on the suction nozzleThe greater the force, the more the suction force is correlated with the resistance to movement of the suction nozzle with respect to the surface to be cleaned. Thus, the larger the suction area, the greater the resistance to movement acting on the suction nozzle during vacuum cleaning of the surface, and as can be inferred from fig. 3, the smaller the suction area, the less the resistance to movement acting on the suction nozzle during vacuum cleaning. Can be in Newton [ N ]]The resistance to movement is measured in units of square meters [ m ] 2 ]The suction area is measured in units.
Fig. 4 is a view of a suction nozzle 1 comprising a first edge 7 and a second edge 19, wherein the suction nozzle 1 comprises a duct 27, which duct 27 is adapted to guide an air flow generated by a vacuum cleaner (shown in fig. 5) from the suction nozzle 1 and further through the cleaning system of the vacuum cleaner. The suction nozzle 1 is arranged in a housing 31, which is described in connection with fig. 1a and 1 b.
Fig. 5 shows an exemplary vacuum cleaner 29, which cleaner 29 has a suction nozzle 1 connected to the vacuum cleaner 29. Thus, by means of the suction nozzle 1, a vacuum cleaner is provided which can facilitate cleaning of a surface. Furthermore, since the suction nozzle 1 is connected to the vacuum cleaner, user-friendliness of the vacuum cleaner can be improved.
Even though embodiments of the various aspects have been described, many different alterations, modifications and the like thereof will be apparent to those skilled in the art. Accordingly, the described embodiments are not intended to limit the scope of the present disclosure.
