Referring to fig. 1, fig. 1 is a schematic structural diagram of a surface cleaning apparatus 100 according to an embodiment of the invention. The embodiment shown in the figures provides a surface cleaning apparatus 100. Surface cleaning apparatus 100 generally includes a soil recovery system. The soil recovery system for recovering soil from a surface to be cleaned comprises a recovery tank 17 for recovering soil, a suction duct and a vacuum extraction assembly for generating a suction airflow flowing along the suction duct. The surface cleaning apparatus 100 may further comprise a cleaning liquid supply system for spraying a cleaning liquid onto the surface to be cleaned or onto a wiping element such as a roller brush.
Referring to fig. 2-7, fig. 2 is a schematic structural view of a recycling bin 17 in one embodiment, fig. 3 is an exploded structural view of the recycling bin 17 in one embodiment, fig. 4 is a sectional view of the recycling bin 17 along a-a in one embodiment, fig. 5 is a sectional view of the recycling bin 17 at another angle along a-a in one embodiment, fig. 6 is a sectional view of the recycling bin 17 along a-a in another embodiment, and fig. 7 is a sectional view of the recycling bin 17 at another angle along a-a in another embodiment. Wherein the arrows in the figure are the airflow direction. The recovery tank 17 shown in the drawings includes a body 171 and an intake duct 172, and a storage space for storing dirt is defined in the body 171. The body 171 includes a bottom wall 1712 and a side wall 1711 extending upwardly from the periphery of the bottom wall 1712, which together define a storage space. The air inlet duct 172 extends through the bottom wall 1712 into the storage space, at least a portion of the air inlet duct 172 being disposed within the storage space. The inlet tube 172 includes an inlet end and an outlet end. The air intake is in fluid communication with a suction port of the surface cleaning apparatus 100. The dirty air flow enters the storage space through the air outlet 1741 of the air inlet tube 172, and in this embodiment, the air inlet tube 172 is entirely disposed in the storage space. The intake pipe 172 is integrally formed with the body 171, and the intake end of the intake pipe 172 is integrally formed with the bottom wall 1712.
A filter 176 is also provided in the recovery tank 17. Referring to fig. 3, the filter 176 is a generally plate-like structure including a plurality of filter holes. The filter 176 is mounted in the body 171, and the filter 176 may be mounted to the intake pipe 172 or the body 171. The filter 176 is used for solid-liquid separation when dirt is discharged from a pouring port (not labeled in the drawing) of the body 171, and at least part of the solid impurities is held in the storage space. When the user finishes cleaning or the recovery tank 17 is full of liquid and needs to be cleaned, the user needs to hold the recovery tank 17 and pour out impurities such as sewage from the pouring opening of the recovery tank 17.
To prevent upward splashing of liquid droplets generated during use, the filter 176 is therefore positioned between the outlet end and a warning level (the wave line in fig. 4 can be considered as a warning water line) in the storage space, which is the highest level that the recovery tank 17 can reach with sewage in normal use. By this arrangement, the liquid in the recovery tank 17 can be effectively prevented from splashing during use. Although the filter 176 can block some splashed liquid, part of the splashed liquid splashes above the filter 176 from a position without the filter 176, and at this time, part of moisture flows to the outlet of the recovery tank 17 along with the gas, and if the gas flow after gas-liquid separation flows to the outlet directly and the flow path is short, the moisture contained in the gas does not have time to be sufficiently condensed into water droplets to drop, so that the water content in the gas increases.
With continued reference to fig. 4-5, a partition plate 1761 is disposed in the storage space, the partition plate 1761 divides the storage space corresponding thereto into two opposite portions, i.e., the space above the water level of the storage space is divided into two portions, a first side of the partition plate 1761 is a gas-liquid separation region 1765, and the other side, i.e., the second side, is a gas circulation region 1766. The partition plate 1761 may be disposed in the gas flowing area 1766, and at least one of two ends of the partition plate 1761 is adjacent to or in contact with an inner wall surface of the body 171 along a width direction of the body 171 (a radial direction of the body 171), specifically, one end of the partition plate 1761 with a plate-shaped structure adjacent to the filter 176 is a bottom end 1762, and two ends adjacent to the bottom end 1762 are a left end 1763 and a right end 1764, respectively, wherein at least one of the left end 1763 and the right end 1764 is adjacent to or in contact with the inner wall surface of the body 171. The reason why the end of the partition plate 1761 is adjacent to the inner wall surface of the body 171 means that the two are very close to each other and the gas passing through the gap formed between the two is very small is that the partition plate 1761 is easy to take and place with less effort. Of course, in order to seal the left and right ends of the partition plate with the inner wall surface, the left and right ends of the partition plate 1761 may contact the inner wall surface of the body 171, and further, the end of the partition plate 1761 contacting the inner wall of the body 171 is provided with a sealing material, which is not described in detail herein, and may be formed of a soft rubber or other common sealing structure. Air outlet 1741 is disposed on a first side of partition plate 1761, filter 176 is disposed on a second side of partition plate 1761, the first side and the second side are disposed on opposite sides of partition plate 1761, and left and right ends of partition plate 1761 are adjacent to or in contact with an inner wall surface of body 171, respectively, so that dirty air flowing out of air outlet 1741 enters the second side of partition plate 1761 from below partition plate 1761 after gas-liquid separation and then flows out of the storage space. Further, an airflow opening 1767 may be provided between the filter 176 and the divider plate 1761 to ensure that a majority of the airflow passes directly from the opening to the outlet of the body 171. By adding divider plate 1761 and filter 176, splashing water droplets are prevented from splashing into gas flow-through area 1766, while increasing the gas flow path. In a further embodiment, the air inlet tube 172 includes an air outlet 1741, and the filter 176 is lower than the bottom of the air outlet 1741 to effectively prevent splashing of the liquid.
Further, the recycling bin 17 includes a cover 178 installed at the pouring opening of the storage space, and a partition plate 1761 is disposed on a side of the cover 178 facing the storage space. Partition 1761 is disposed on a side of cover 178 facing the storage space such that when cover 178 is removed, partition 1761 is removed, and in a specific embodiment, partition 1761 may be integrally formed with cover 178. The cover 178 is provided with an exhaust port 1784 located directly above the filter 176.
Referring to fig. 6-7, in the embodiment shown, a divider plate 1761 is positioned above filter 176, or filter 176 is positioned below the lowest end of divider plate 1761. As shown in fig. 6, the partition plate 1761 divides the storage space corresponding thereto into two opposite portions, i.e., the space above the alarm water level of the storage space is divided into two portions, the first side of the partition plate 1761 is a gas-liquid separation region 1765, and the other side, i.e., the second side, is a gas circulation region 1766. I.e., at least a portion of filter 176 is located on a second side of divider plate 1761. Divider plate 1761 may be a thin plate-like structure, it being understood that divider plate 1761 may be a straight plate, or a curved plate, or may have other shapes that, in combination with other structures, form a barrier member. The suction air flow carrying the dirt enters the gas-liquid separation region 1765 through the air inlet pipe 172 and then is subjected to gas-liquid separation, and the gas after the gas-liquid separation flows through the gas circulation region 1766 and then is discharged out of the storage space. Thus, the partition plate 1761 is matched with the filter 176, which not only can prevent most of splashed liquid from splashing to the gas circulation area 1766, but also can effectively increase the flowing flow of gas, so that the water vapor carried in the gas is condensed and dropped as much as possible.
With continued reference to fig. 4, in one embodiment, the recovery tank 17 includes a cover 178 mounted at the pour opening of the storage space, and a divider plate 1761 is disposed on a side of the cover 178 facing the storage space. Partition 1761 is disposed on a side of cover 178 facing the storage space such that when cover 178 is removed, partition 1761 is removed, and in a specific embodiment, partition 1761 may be integrally formed with cover 178. The cover 178 is provided with an exhaust port 1784 located directly above the filter 176. When the cover 178 is mounted to the body 171, the partition 1761 substantially divides the storage space above the plane of the filter 176 into a gas-liquid separation zone 1765 and a gas flow-through zone 1766. At least one of two ends of the partition plate 1761 is adjacent to or in contact with the inner wall surface of the body 171 along the width direction of the body 171 (radial direction of the body 171), specifically, one end of the partition plate 1761 of the plate-shaped structure, which is adjacent to the filter 176, is a bottom end 1762, and two ends of the partition plate 1761, which are adjacent to the bottom end 1762, are a left end 1763 and a right end 1764, respectively, wherein at least one of the left end 1763 and the right end 1764 is adjacent to or in contact with the inner wall surface of the body 171. The reason why the end of the partition plate 1761 is adjacent to the inner wall surface of the body 171 means that the two are very close to each other and the gas passing through the gap formed between the two is very small is that the partition plate 1761 is easy to take and place with less effort. Of course, in order to seal the left and right ends of the partition plate with the inner wall surface, the left and right ends of the partition plate 1761 may contact the inner wall surface of the main body 171, and further, the end of the partition plate 1761 contacting the inner wall of the main body 171 may be provided with a sealing material.
An air flow opening 1767 is defined between the filter 176 and the partition plate 1761, and the uppermost end of the air flow opening 1767 is lower than the lowermost end of the air outlet 1741. Thus, since the gas flowing area 1766 is on the other side of the gas outlet 1741, the separated gas and liquid move in opposite directions, and at the same time, the gas first passes downward through the gas flow opening 1767 and then flows upward out of the storage space, so that the flow path of the gas is increased, and most of the gas after gas-liquid separation enters the gas flowing area 1766 from the gas-liquid separation area 1765 through the gas flow opening 1767. Specifically, after the dirty gas flow flowing out from the gas outlet 1741 is subjected to gas-liquid separation, most of the gas enters the other side of the partition plate 1761 from one side of the partition plate 1761 through the gas flow opening 1767 and then flows out of the storage space, because a small part of the gas may pass through the filter hole from the lower part of the filter 176 and enter the gas flow-through area 1766, and a small part of the gas enters the gas flow-through area 1766 through the gap between the filter 176 and the inner wall surface of the body 171, but the gas in the two parts is relatively small and has little influence.
Referring to fig. 8-13, fig. 8 is a schematic diagram of a recovery tank 17 in yet another embodiment. Fig. 9 is an exploded view of the recovery tank 17 shown in fig. 8. Fig. 10 is a sectional view of the recovery tank 17 shown in fig. 8 taken along the direction B-B. Fig. 11 is a cross-sectional view of the recovery tank 17 shown in fig. 8 taken at another angle in the direction B-B. Fig. 12 is a sectional view of the recovery tank 17 shown in fig. 8 taken along the direction C-C. Fig. 13 is a schematic structural view of the recovery tank 17 shown in fig. 8 with the lid 178 removed. As shown in the illustrated embodiment, the recovery tank 17 further includes a gas-liquid separator 175 disposed in a gas-liquid separation zone 1765 configured for gas-liquid separation of the suction gas stream carrying the contaminants. Specifically, a gas-liquid separator 175 is disposed at the gas outlet 1741 of the gas inlet pipe 172, and the gas-liquid separator 175 is configured to separate the fluid flowing out of the gas outlet 1741 of the gas inlet pipe 172 into gas and liquid. The outlet of the intake pipe 172 may be directed in any direction, and the gas-liquid separator 175 may be disposed at the outlet. The gas-liquid separator 175 includes a body 171 and one or more liquid deflectors 1751 disposed in the body 171. When the flow guide is one, the shape may be a quarter of a sphere or a sphere-like structure. When the guide portion is plural, a plurality of liquid guide portions 1751 are arranged at intervals at the outlet of the air intake pipe 172. The liquid guide 1751 functions to converge and guide the liquid toward the bottom of the sump. The gas outlets are disposed between two adjacent liquid deflectors 1751. The number of gas outlets is at least one. Wherein the bottom end 1762 of the liquid conducting portion 1751 is lower than the top end of the gas outlet in the direction of gravity. Specifically, after the water-air mixture is discharged through the outlet of the air inlet pipe 172, most of the water mist and water drops collide with the liquid diversion portion 1751 and then flow downward along the inner wall of the liquid diversion portion 1751 under the influence of gravity after being reduced due to the wall attachment characteristic, and the gas flows in the direction opposite to that of the liquid and is separated from the liquid, so that gas-liquid separation is realized. In one embodiment, the gas-liquid separator 175 and the filter 176 are integrally formed, and the filter 176 is lower than the gas-liquid separator 175 in a vertical direction.
Referring to fig. 9, to cooperate with gas-liquid separator 175, divider plate 1761 is an inverted U-shape that includes oppositely disposed open and closed ends, the open end being disposed on cover 178, and divider plate 1761 defines a U-shaped opening that engages gas-liquid separator 175 to divide the storage space above the plane of filter 176 into a gas-liquid separation region 1765 and a gas recirculation region 1766. The lowest end of partition plate 1761 is lower than the lowest end of gas-liquid separator 175.
In other embodiments, gas-liquid separator 175 may be integrally formed with filter 176, and divider plate 1761 may be integrally formed with filter 176; it is understood that the gas-liquid separator 175, the partition plate 1761 and the filter 176 may be integrally formed.
In one embodiment, the filter 176 is located between the lowest end of the divider plate 1761 and a top-of-range level in the storage space, which is the highest level of waste water that can be reached during normal use of the recovery tank 17, and is typically marked on the body to alert the user. Further, the distance between the filter 176 and the alarm water level along the gravity direction is a first preset distance, the distance between the filter 176 and the air outlet end is a second preset distance, and the first preset distance is smaller than the second preset distance. In a preferred embodiment, the first predetermined distance is less than 15mm, which corresponds to the filter 176 being positioned against the water line. In order to detect the liquid level information in the recycling tank 17 and ensure the safe use of the device, the recycling tank 17 further comprises at least one liquid level detection device for detecting the water level information in the storage space, wherein the liquid level detection device is arranged above the filter 176. Specifically, liquid level detection device generally includes two conducting strips, and when two conducting strips submerged liquid, switch on between two conducting strips, signals, reminds the user that the sewage case needs to be cleared up. The liquid level detection device is arranged above the filter 176, the filter 176 can resist most splashed liquid drops, and the splashing of water drops in the recovery box 17 to the probe is reduced. If the water drops form a conductive water film near the probe, even if the conductive sheet is not soaked by liquid, the conductive sheet can be conducted greatly, so that false alarm can be generated, and a user has to clean the recovery box 17 and the liquid level detection device. Referring to fig. 13, the mounting bracket 1791 of the conductive sheet and the partition plate 1761 may be formed as a single structure, and they may be detachable from each other or integrally formed.
Referring to fig. 14, fig. 14 is a schematic sectional view of a recovery tank of still another embodiment. In this embodiment, the basic structure of the recycling bin 17 may be substantially the same as that of the above-described embodiment, and the only difference is the positional relationship between the filter 176 and the partition plate 1761, and in this embodiment, the gas flowing out from the gas outlet 1741 of the gas inlet pipe 172 flows to the outlet of the body after gas-liquid separation, wherein the filter 176 and the partition plate 1761 are in contact with each other. The filter may be disposed under the partition plate, with an upper surface of the filter contacting a bottom end of the partition plate. The filter may be further provided at one side of the partition plate, in which case, the end of the filter is in contact with the side of the partition plate. Most of the gas flow after gas-liquid separation flows from the gas-liquid separation area to the gas circulation area through the meshes of the filter. Therefore, the water vapor and the liquid carried in the gas are blocked by the filter when passing through the filter, so that the liquid drops can be effectively prevented from splashing to the space above the filter, and part of the water vapor carried in the gas can be removed.
While embodiments of the invention have been described above, it is not limited to the applications set forth in the description and the embodiments, which are fully applicable in various fields of endeavor to which the invention pertains, and further modifications may readily be made by those skilled in the art, it being understood that the invention is not limited to the details shown and described herein without departing from the general concept defined by the appended claims and their equivalents.
