Description

Area

[0001] The technology relates to the field of industrial vacuum cleaner devices, specifically focusing on vacuum cleaners with collection bags, in particular dust extractors for removing dust, dirt and deposits. background

[0002] It is common practice in industrial workplaces, such as construction sites and factories, to use vacuuming devices, such as dust extractors, to keep the workspace free of dirt, debris, and dust particles like concrete dust. Some dust extractors can be used for dry dirt and dust, while others can also be used to vacuum up liquids.

[0003] It is desirable to be able to empty the vacuum unit when it is full, thereby reducing the effort required by the user. This can be particularly relevant when the user is cleaning a wet work area.

[0004] It is known to use a lining, such as a disposable bag, to reduce the amount of contamination that the user has to handle when emptying the vacuum cleaner device.

[0005] Another advantage of using a liner is that it increases the user's protection against inhaling harmful dust, especially when emptying a vacuum cleaner. In fact, industrial dust extractors typically comply with certain standards and regulations, such as classifications as Class L, M, and H. According to most of these standards and regulations, the use of a liner is required for the aforementioned protective reasons related to reducing the user's dust inhalation.

[0006] Such an arrangement is shown in US 2022 / 0400917. However, a problem with this arrangement is that the disposable bag must overlap the outside of the vacuum cleaner device. This means that an inadequate seal is provided, and the disposable bag can be drawn into the motor fan assembly, causing a blockage. Brief description

Detailed description

[0026] The detailed description below provides information and examples of the disclosed technology with sufficient detail to enable a person skilled in the art to put the invention into practice.

[0027] It is known to use vacuuming devices, such as dust extractors, in industrial workplaces like construction sites and factories to keep the work area clean, particularly vacuum cleaners that use a liner, such as a disposable bag. For reasons of protection and convenience, bags can be advantageous, especially when emptying the vacuum cleaner. However, liners normally have to overlap the outside of the vacuum cleaner, which leads to a poor seal that can cause the liner to be drawn into a motor fan of the vacuum cleaner assembly, resulting in a blockage. Embodiments of the present invention address this problem.

[0028] Fig. Figure 1 shows a perspective view of a vacuum cleaner device 100, such as a dust extractor, according to an example. The vacuum cleaner device 100 is arranged such that it enables cleaning processes by generating a negative pressure airflow that carries away dirt, deposits and liquids that are carried along in the airflow from a dirty air inlet 108.

[0029] As in Fig. As shown in Figure 1, the vacuum cleaner device 100 has a housing 102 with at least two sections, e.g., a suction head section 104 and a collection container section 106. The suction head section 104 can be mounted on the collection container section 106. The housing 102 is designed to enclose and protect the internal components of the vacuum cleaner device 100. The housing 102 is further designed to allow airflow through the vacuum cleaner device 100 from the dirty air inlet 108. While the arrangement of the vacuum cleaner device 100, as shown in Figure 1, is Fig. Figure 1 shows two sections, e.g. a suction head section 104 and a collection container section 106; in other examples there may be a single section or more than two sections.

[0030] The housing 102 can be constructed of a durable material such as plastic or metal. In some embodiments, the housing 102 can be formed from an impact-resistant body reinforced with integrated steel rods. In some embodiments, the housing 102 can be made of polypropylene or a similar durable material.

[0031] The housing 102 may be box-shaped, thus providing a compact and stable construction for the vacuum cleaner device 100. By providing a box-shaped housing 102, the housing 102 can be compatible with other toolboxes and stackable and / or lockable with them. While the examples illustrated in the figures depict a box-shaped vacuum cleaner device 100, the housing 102 can have any suitable shape, e.g., a cylindrical shape with a round cross-section.

[0032] The housing 102 may include mounting elements 112 for securely attaching a toolbox or other accessories. The housing 102 may optionally also include latches 122 for securing the collection container section 106 and the suction head section 104 to one another. This means that the suction head section 104 can be detached from the collection container section 106 by the user to empty a collection container 114 located within the collection container section 106. In some embodiments, the latches 122 can be replaced by any other suitable fastening to securely fix the suction head section 104 to the collection container section 106. In some embodiments, the latches 122 are configured to exert a force on the suction head section 104 and the collection container section 106, pressing the suction head section 104 and the collection container section 106 together.This can help to maintain an airtight seal between the suction head section 104 and the collection container section 106.

[0033] The suction head section 104 and the collection container section 106 will now be discussed in more detail.

[0034] In one embodiment, the suction head section 104 is a volume of the vacuum cleaner device 100 located within a part of the housing 102, as shown in Fig. 1 shown. The suction head section 104 contains one or more operating components of the vacuum cleaner device 100, such as the motor fan assembly 118 (best shown in Fig. 2 shown). The suction head section 104 is configured to generate a negative pressure airflow along an airflow path 130 within the vacuum cleaner device 100, to draw in air through the dirty air inlet 108, and to expel clean air through the clean air outlet 110. The airflow path 130 is described below with respect to Fig. 5 and Fig. 6 described in more detail.

[0035] Similarly, the collection container section 106 is a volume of the vacuum cleaner device 100 that is located inside the housing 102 and is separated from the operating components of the vacuum cleaner device 100 in the suction head section 104.

[0036] As mentioned above, the collection tray section 106 includes the collection tray 114, which is designed to collect and store dirt, debris, or water entrained in the airflow drawn in at the dirty air inlet 108. The collection tray section 106 is in fluid communication with the motor fan assembly 118 and the dirty air inlet 108 and is positioned on the airflow path 130. As mentioned above, the collection tray section 106 can be removed for easy disposal of the collected dirt by the user, for example, by releasing the latches 122. Once the latches 122 are released, the suction head section 104 can be lifted off the collection tray section 106.

[0037] As in Fig. As shown in Figure 1, the dirty air inlet 108 is mounted in the housing 102 within the suction head section 104. The dirty air inlet 108 is designed to receive air carrying dirt and debris from a cleaning tool accessory, such as a hose (not shown) or other cleaning accessory (not shown). The dirty air inlet 108 is in fluid communication with the collection container 114 to allow the airflow from the dirty air inlet 108 to the collection container 114. In some embodiments, the dirty air inlet 108 is connected to an inlet line 140, which is connected to the collection container 114. The inlet line 140 directs the airflow path 130 from the dirty air inlet 108, mounted in the suction head section 104, to the collection container 114 in the collection container section 106.

[0038] Fig. Figure 2 shows an expanded perspective view of some components of the suction head section 104 of a vacuum cleaner device 100, which will now be discussed in more detail.

[0039] In one embodiment, a filter 116 is arranged to remove dirt and deposits from the airflow in the vacuum cleaner device 100 before the airflow leaves the collection container 114. In this way, the filter 116 is located upstream of the motor fan assembly 118 and removes small particles from the airflow before they enter the motor fan housing 124.

[0040] In further embodiments, the vacuuming device 100 has additional filters, barriers, or nets (not shown) located downstream of the motor fan assembly 118. For example, the additional filter can be mounted next to the clean air outlet 110 to prevent the release of fine dust particles at the workplace. The filter 116 can be made of a variety of materials suitable for trapping dirt and debris while allowing air to pass through. In some embodiments, the filter 116 can be a pleated filter. Other filter types can be used in other embodiments. The filter 116 can be designed to be easily removable and replaceable, which facilitates the regular maintenance of the vacuuming device 100.

[0041] As mentioned above, the motor fan assembly 118 is mounted in the suction head section 104. In some embodiments, the motor fan assembly 118 is configured to generate an airflow within the vacuum cleaner device 100.

[0042] Fig. Figure 3 shows a perspective view of the vacuum cleaner device 100, with part of the housing 102 removed to show the interior of the suction head section 104. The motor fan assembly 118 mounted inside the suction head section 104 includes a motor 120 (as shown in Figure 3). Fig. 3) and a fan (not shown) that work together to draw in air through the dirty air inlet 108 and expel it through the clean air outlet 110. The motor-fan assembly 118 can be configured to provide high suction power to enable the vacuum cleaner 100 to effectively pick up dirt and debris from the work environment.

[0043] In one embodiment, the motor fan assembly 118 is housed within a motor fan housing 124 mounted in the suction head section 104. The motor fan housing 124 is designed to protect the motor 120 and the fan from damage and to facilitate efficient airflow through the motor fan assembly 118.

[0044] In some embodiments, the motor fan assembly 118 includes a motor fan inlet 128 and a motor fan outlet 126, which are formed from a portion of the motor fan housing 124. The motor fan inlet 128 is configured to receive the airflow from the collection container 114. The motor fan inlet 128 is configured to direct the airflow into the motor fan assembly 118.

[0045] In some embodiments, the motor fan assembly 118 is connected to a power source that is selectively controlled via a user interface. The power source can be a battery 170 and / or a mains power supply. The use of a battery 170 or a mains power supply with a motor fan assembly 118 is known. Similarly, controlling such a motor fan assembly 118 via a user interface is known and will not be discussed in detail here.

[0046] In some embodiments, the vacuum cleaner 100 includes a partition plate 132. The partition plate 132 can be mounted in the housing 102 and is configured to separate the suction head section 104 of the vacuum cleaner 100 from the collection container section 106 of the vacuum cleaner 100. In some embodiments, the partition plate 132 can be fixed to the suction head section 104. In this case, both the suction head section 104 and the partition plate 132 can be removed together when the suction head section 104 is detached from the collection container section 106. In some embodiments, the partition plate 132 is part of the suction head section 104 and forms an outer wall of the suction head section 104. The partition plate 132 serves as a barrier that separates the collection container section 106 from the suction head section 104.

[0047] In one embodiment, the partition plate 132 includes a filter mounting assembly 134. The filter mounting assembly 134 is designed to securely attach the filter 116 to the partition plate 132. The filter mounting assembly 134 may include various features to enable the secure attachment of the filter 116, such as clips, screws, or other fastening mechanisms. The filter mounting assembly 134 may be designed to allow easy removal and replacement of the filter 116, thus facilitating the regular maintenance of the vacuum cleaner device 100.

[0048] In some embodiments, the separating plate 132 includes guide legs 136. The guide legs 136 are designed to project into the collection container section 106 and guide the separating plate 132 into the correct alignment with the collection container section 106. The guide legs 136 can be designed to provide a secure fit while simultaneously allowing easy removal and replacement of the separating plate 132. The guide legs 136 can be constructed of a durable material such as plastic or metal.

[0049] In one embodiment, the partition plate 132 includes a sealing element 138. The sealing element 138 is designed to seal against the wall of the housing 102 to prevent air from escaping the vacuum cleaner device 100. The sealing element 138 can be made of a flexible material, such as rubber or silicone, to provide a tight seal while allowing easy removal and replacement of the partition plate 132.

[0050] In some embodiments, the separating plate 132 may optionally include a recess designed to accommodate a module insert with one or more components of the vacuum cleaner device 100.

[0051] As mentioned above, the vacuum cleaner 100 includes an airflow path 130 extending between the dirty air inlet 108 and the clean air outlet 110. The airflow path 130 is designed to guide the airflow through the vacuum cleaner 100 to ensure that the air passes through the collection container 114, the filter 116, and the motor fan assembly 118. The airflow path 130 may also pass through one or more operating components of the vacuum cleaner 100. The airflow path 130 may be designed to minimize resistance to the airflow in order to maximize the efficiency of the vacuum cleaner 100.

[0052] Airflow path 130 is now being used with reference to Fig. 5 and Fig. 6 described in more detail. Fig. Figure 5 shows a perspective view of the vacuum cleaner device 100, with the airflow path 130 through the collection container section 106 indicated. Fig. 6 shows a similar drawing to Fig. 5 and shows a perspective view of the vacuum cleaner device 100 with the airflow path 130 through the suction head section 104.

[0053] The airflow path 130 enters the vacuum cleaner device 100 via the dirty air inlet 108. As mentioned above, the dirty air inlet 108 is connected to the collection container 114 via the inlet line 140. The inlet line 140 has a 90-degree bend, so that the airflow path 130 enters the collection container 114 from above. That is, the airflow path 130 enters the collection container 114 from the direction of the suction head section 104.

[0054] The inlet pipe 140 includes a collection container inlet 142, as shown in Fig. Figure 5 shows that the inlet opening can be shaped to direct the airflow path 130 in a specific direction into the collection container 114. For example, the airflow path 130 can be directed towards the bottom or side of the collection container 114 to promote the falling out of dirt and debris entrained in the airflow and their collection at the bottom of the collection container 114.

[0055] The airflow path 130 exits the collection container 114 via the filter 116. As discussed above, the filter 116 is designed to remove dirt and debris carried along by the airflow that has not already been flung out of the airflow into the collection container 114. The filter 116, together with the inlet line 140, is also mounted in the partition plate 132.

[0056] In this way, both the inlet line 140 and the filter 116 allow the airflow path 130 to enter the collection container 114 and to exit it in the same direction.

[0057] In Fig. Section 6 describes in more detail the airflow path 130 through the suction head section 104. After exiting the filter 116, the airflow path 130 enters the motor fan assembly 118. As discussed above, the motor fan assembly 118 has a motor fan inlet 128 that receives the airflow path 130 from the filter 116. The airflow path 130 then winds around the spiral motor fan housing 124 and exits the motor fan assembly 118 via the motor fan outlet 126. The airflow path 130 then extends through the suction head section 104 and exits via the clean air outlet 110.

[0058] The airflow path 130 enters the collection container 114 via a collection container inlet 142. Additionally, the airflow path 130 exits the collection container 114 via a collection container outlet 144. The inlet line 140 is in fluid communication with the collection container inlet 142. Likewise, the collection container outlet 144 is in fluid communication with the filter 116.

[0059] The collection container inlet 142 and the collection container outlet 144 are mounted in the partition plate 132. For example, in Fig. 5 and Fig. As shown in Figure 6, the filter 116 can be mounted in the collection container outlet 144.

[0060] Therefore, as described above, the separating plate 132 includes both the collection container inlet 142 and the collection container outlet 144, allowing the collection container inlet 142 and the collection container outlet 144 to be located in the same plane. This means that both the airflow into the collection container 114 and the airflow out of the collection container 114 can be arranged in the same direction. This means that the filter 116 and the collection container inlet 142 can be mounted within a collection bag opening 164 of a collection bag 146. Both the collection bag opening 164 and the collection bag 146 are described below with reference to Fig. 4a, Fig. 4b and Fig. 7 described in more detail.

[0061] Filter 116 is, for example, in Fig. 5 and Fig. Figure 6 shows the filter 116 mounted inside the collection container outlet 144. However, in some embodiments, the filter 116 can also be mounted elsewhere, e.g., inside the suction head section 104.

[0062] For example, in Fig. 5 and Fig. As shown in Figure 6, both the filter 116 and the collection container inlet 142 may project into the volume of the collection container 114 when the suction head section 104 is mounted on the collection container section 106. By arranging the filter 116 and the collection container inlet 142 in such a way that they project into the collection container 114, the dirt and deposits can be more effectively flung out of the swirling airflow within the collection container 114. In some embodiments, however, the filter 116 may not project into the collection container 114 when the suction head section 104 is mounted on the collection container section 106.

[0063] The following descriptions of embodiments refer to Fig. 4a and Fig. 4b is discussed. Fig. Figures 4a and 4b show a schematic view of a vacuum cleaner device 100 with a collection bag 146 according to the first arrangement and a second arrangement.

[0064] In the Fig. In the arrangement shown in Figure 4a, a collection bag 146 is mounted inside the collection container 114 and in the collection container section 106. This is similar to prior art arrangements, for example, as described above with reference to US 2022 / 0400917. The collection bag 146 overlaps an outer surface 148 of the collection container section 106. This means that the collection bag 146 extends beyond the housing 102 when the suction head section 104 is mounted on top of the collection container section 106.

[0065] In other words, the collection bag 146 is enclosed between the walls of the suction head section 104 and the collection container section 106. This means that the collection bag 146 prevents a good seal between the suction head section 104 and the collection container section 106, and air can be drawn into the volume of the collection container section 106.

[0066] This means that the pressure of a first volume 150 of the collection container 114 inside the collection bag 146 is not equal to the pressure of a second volume 152 of the collection container 114 between the collection bag 146 and an inner surface 154 of the collection container section 106.

[0067] Accordingly, the unequal pressure between the first volume 150 and the second volume 152 can cause the collection bag 146 to be sucked towards the collection container outlet 144.

[0068] In contrast, in one embodiment the collection bag 146 is mounted completely within the volume of the collection container 114, as shown in Fig. Figure 4b shows that in this case, the collection bag 146 does not protrude from the housing 102. Accordingly, the suction head section 104 and the collection container section 106 can interlock and provide an airtight seal between them.

[0069] This means that no air from outside the vacuum cleaner device 100 can enter the collection container 114 via the connection between the collection container section 106 and the suction head section 104. Instead, the collection bag 146 is located, as shown in Fig. 4b shown, completely within the volume of the collection container 114.

[0070] The collection bag 146 is mounted inside the collection container 114 via a collection bag holder 156. Fig. Figure 4b shows a cross-sectional view of the collection bag holder 156.

[0071] In some embodiments, the circumference 158 of the collection bag 146 is folded over the collection bag holder 156. The circumference 158 remains in place relative to the collection bag holder 156 and thus keeps the collection bag 146 open when it is mounted inside the collection container 114.

[0072] Since the collection bag 146 is completely mounted inside the collection container 114, the pressure is the same in a first volume 150 inside the collection bag 146 and in a second volume 152 between the collection bag 146 and an inner surface 154. This means that the collection bag 146 is not pulled towards the collection container outlet 144 during operation of the vacuum cleaner device 100. Accordingly, the collection bag 146 remains in its position relative to the collection container 114 during operation and collects dirt and debris carried along in the airflow.

[0073] In some embodiments, the collection bag holder 156 is a retaining rim 166 made of a rigid material to securely engage the circumference of the collection bag 158.

[0074] As in Fig. As shown in Figure 4b, the airflow path 130 extends into the collection bag 146. The collection bag 146 is impermeable and prevents the airflow path 130 from passing through it. This means that the collection bag 146 itself directs the airflow from the collection container inlet 142 to the collection container outlet 144. This is because the collection bag 146 does not allow any air to escape. However, in other embodiments, which may be less preferred, the collection bag 146 can be made of an air-permeable material.

[0075] In some embodiments, the collection bag 146 is disposable. This means that the user can simply remove the collection bag 146 when the collection container 114 is full and easily replace the collection bag 146.

[0076] The material of the collection bag 146 can be any suitable material for trapping and retaining dirt and debris carried along in the airflow. For example, the collection bag 146 can be a plastic bag. In some embodiments, the collection bag 146 can be any suitable retainer or lining. For example, a suitably heavy paper bag can be used that substantially prevents air from passing through. Alternatively, the collection bag 146 can be a rigid lining (not shown).

[0077] In some embodiments, the collection bag holder 156 is held on a collection container lip 168. The collection container lip 168 is the circumference of a wall of the collection container section 106, which engages with the suction head section 104.

[0078] This means that when the collection bag circumference 158 is mounted on the collection bag holder 156, it is held close to the circumference of the collection container 114. The collection bag holder 156 is in Fig. Figure 4b shows the collection bag holder mounted near the lip 168 of the collection container. In some embodiments, the collection bag holder 156 is mounted on a projecting shoulder 160. The projecting shoulder 160 has a shoulder recess 162 for receiving the collection bag holder 156.

[0079] As mentioned above, the collection bag holder 156 has a rigid retaining rim 166. When the collection bag 146 is mounted on the rigid retaining rim 166, the collection bag holder 156 holds the collection bag 146 open and defines the collection bag opening 164, as shown in Fig. 4b shown. If necessary, the overlapping section of the collection bag 146 above the holder edge 166 can be attached to the collection bag 146 itself or to the collection bag holder 156.

[0080] The collection bag holder 156 engages in the projecting shoulder 160 and is held in place by it. In some embodiments, the projecting shoulder 160 is integral with the collection container 114. In other embodiments, however, the projecting shoulder 160 may be a separate component attached to the collection container 114. Additionally or alternatively, the collection bag holder 156 may be attached to the collection container 114 by a clip arrangement (not shown). The clip arrangement comprises at least one clip positioned around the collection container lip 168 of the collection container 114. In some embodiments, a plurality of clips are spaced circumferentially around the lip 168 of the collection container 114. In other embodiments, any suitable means or mechanism may be used to secure the collection bag holder 156 to the collection container 114.

[0081] In some embodiments, the collection container 114 does not have a projecting shoulder 160. Instead, the cross-sectional shape of the bag holder 156 is slightly smaller than the cross-sectional shape of the collection container 114. In this way, the bag holder 156 provides a positive connection between itself and the collection container 114 when the user places the bag holder 156 and the bag holder 156 into the collection container 114. This ensures that the bag 146 and the bag holder 156 remain fixed relative to the collection container 114 during operation of the vacuum cleaner 100.

[0082] In some embodiments, the projecting shoulder 160 can alternatively be a projecting shoulder section (not shown) of the collection container 114. The projecting shoulder section (or the projecting shoulder 160) is arranged to receive and retain the collection bag holder 156 near the lip 168 of the collection container. The projecting shoulder section has a smaller cross-section and prevents the collection bag holder 156 from falling onto the bottom of the collection container 114.

[0083] For a more detailed description of the embodiments, reference is now made to Fig. 7a to 7f taken. Fig. Figures 7a to 7f show a perspective view of the vacuum cleaner device 100 with the collection bag 146. Fig. Figures 7a to 7f show the vacuum cleaner device 100 only with the collection container section 106 for the sake of clarity.

[0084] In Fig. Figure 7a shows the vacuum cleaner device 100 with only the collection container section 106 and without the collection bag holder 156. This would be the arrangement of the vacuum cleaner device 100 if the user had removed the suction head section 104 to empty the collection bag 146.

[0085] As in Fig. As shown in Figure 7b, the collection bag holder 156 is detachable from the collection container section 106. The collection bag holder 156 is also detachable from the suction head section 104. The collection bag holder 156 can be mounted inside the collection container section 106, as shown in Figure 7b. Fig. 7c shown.

[0086] For example, the user might not want to use a collection bag 146 to collect dirt and debris, and instead only the collection container 114. In this case, the collection bag holder 156 is mounted near the collection container lip 168, but without the collection bag 146, as discussed above.

[0087] If the user wishes to insert a collection bag 146 into the collection container 114, he places the collection bag holder 156 around the collection bag 146, as shown in Fig. 7d shown.

[0088] The user can then fold a section of the collection bag 146 over the collection bag holder 156, as shown in Fig. Figure 7e shows that, if necessary, the user can attach clips (not shown) to the collection bag holder 156 to clamp the collection bag 146 to the collection bag holder 156. However, this may not be necessary and is optional.

[0089] After the user has removed the collection bag 146, as described in Fig. As shown in Figure 7e, he folds the container and inserts both the collection bag holder 156 and the collection bag 146 into the collection container 114. As shown in Figure 7e, he places the collection bag holder 156 and the collection bag 146 into the collection container 114. Fig. As shown in Figure 7f, the collection bag 146 and the collection bag holder 156 are completely contained within the collection container section 106.

[0090] When the user attaches the suction head section 104 to the collection container section 106, the collection bag 146 accordingly does not protrude from the vacuum cleaner device 100.

[0091] Fig. Figures 7d to 7f show an oversized collection bag 146, which must be folded over the collection bag holder 156. Collection bags 146 of other sizes can also be used. For example, the size of the collection bag 146 can be the same height as the depth of the collection container 114. In this case, the collection bag holder 156 can be attached to the collection bag 146 via the collection bag circumference 158, instead of being folded over the collection bag holder 156. In fact, any suitable mechanism can be used to attach or secure the collection bag 146 to the collection bag holder 156.
