Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of surface cleaning apparatuses, and in particular to a cleaning base and a surface cleaning machine provided with the cleaning base. BACKGROUND

[0002] Surface cleaning apparatuses using cleaning liquid, such as water, to perform cleaning operation have been widely used in daily life. For example, wet floor cleaning apparatuses capable of using water or water / cleaner mixture to scrub the floor, which are provided with a recovery container to recover used cleaning liquid, and the dirt on the floor entrained by the used cleaning liquid which has become dirty liquid can be recovered into the recovery container by means of a suction motor or the like.

[0003] In the process of recovering the dirty liquid and the dirt, the wet floor cleaning apparatuses mentioned above often leave some residual water on the cleaned floor due to the liquid that cannot be completely recovered; after using the wet floor cleaning apparatus, in order to avoid the residual water being stepped on by the user to cause secondary pollution, the user has to wait for a period of time before entering the space where the floor is located, which will bring trouble to the user.

[0004] In the prior art, in order to reduce the amount of residual water on the floor, some wet floor cleaning apparatuses only allow a very low flow of cleaning liquid to flow onto the floor per unit time, which can avoid too much water remaining on the cleaned floor, but the low flow will also mean that the amount of dirty liquid entraining dirt is reduced, which may weaken the ability of the wet floor cleaning apparatus to clean the floor; some wet floor cleaning machines are provided with a hot air system on the apparatus, which blows dry the floor while using water or water / cleaner mixture to scrub the floor; but since the time for scrubbing the floor is very short, even if the hot air system is controlled according to the maximum working power of the wet floor cleaning apparatus, it is difficult to dry the floor in such a short time, and due to the use of the hot air system, the working noise of the wet floor cleaning apparatus is extremely large.

DETAILED DESCRIPTION ​​​​​

[0036] The surface cleaning machine of this application is configured to contact the surface to be cleaned using a cleaning base; the surface to be cleaned is typically a hard surface, such as a floor or tile surface. The cleaning base scrubs the surface with a cleaning liquid, while simultaneously thoroughly recovering the used cleaning liquid and any debris present on the surface. This surface cleaning machine solution can be applied to various types of cleaning equipment.

[0037] The terms “up” and “down” mentioned below are oriented relative to the surface cleaning base on the surface to be cleaned, and the terms “front” and “back” are oriented relative to the direction in which the operator stands on the surface to be cleaned and pushes the surface cleaning machine (i.e., the pushing direction from back to front).

[0038] Figure 1 This application illustrates a surface cleaning machine 10; the surface cleaning machine 10 is an upright machine comprising a cleaning base 1 and a handle body portion 2 located on the upper side of the cleaning base 1. The lower part of the handle body portion 2 is pivotally connected to the cleaning base 1 via a swivel joint 3. The handle body portion 2 has a storage position that is upright relative to the cleaning base 1 for easy storage and a working position that is tilted backward relative to the cleaning base 1 for easy pushing of the surface cleaning machine 10 by the user.

[0039] like Figures 1-3 As shown, the cleaning base 1 has a seat 11, which includes a front part 111, a rear part 112, a top part 113, and a bottom part 114.

[0040] like Figures 2-7 As shown, a front agitation chamber 12 is located at the front 111, and a rear agitation chamber 13 is located at the rear 112. A suction nozzle 14 is disposed adjacent to the front agitation chamber 12. The front agitation chamber 12 contains a rotatable wet cleaning roller 15, a liquid distributor 16 partially extending into the front agitation chamber 12, and a scraper roller member 161. The rear agitation chamber 13 contains a dry wiping roller 18 and a dryer 19. This arrangement separates the wet cleaning roller 15 and the dry wiping roller 18 in the front-to-back direction, allowing the cleaning base 1 to be supported on the surface to be cleaned by the wet cleaning roller 15 and the dry wiping roller 18. In other words, within the same working time, the cleaning base 1 can simultaneously clean the surface using both the wet cleaning roller 15 and the dry wiping roller 18.

[0041] The front portion 111 includes a front cover plate 1111 that covers the upper side of the wet cleaning roller 15. The lower portion of the front agitation chamber 12 has a first lower opening 121, and the front portion of the front agitation chamber 12 has a front opening 122, which communicates with the first lower opening 121. The lower portion and the front portion of the wet cleaning roller 15 protrude from the first lower opening 121 and the front opening 122, respectively, to contact the surface to be cleaned.

[0042] The wet cleaning roller 15 includes a first roller body 151 defining a rotation axis X1 extending in a horizontal direction, and a first cleaning element 152 covering the outer peripheral side surface of the roller body 151, the first cleaning element 152 being configured to be able to be infiltrated by a cleaning liquid such as water. The roller diameter D1 of the first roller body 151 is preferably 50-60 mm. In this example, the first cleaning element 152 is a fiber nap, for example the nap length L1 of the first cleaning element 152 is 5-10 mm. In other embodiments, the first cleaning element can also be a sponge, a fabric, or other types.

[0043] The cleaning base 1 is further provided with a first motor (not shown in the figure) in driving connection with the wet cleaning roller 15 to drive the wet cleaning roller 15 to rotate about the rotation axis X1.

[0044] The liquid distributor 16 is oriented towards the wet cleaning roller 15 and is configured to distribute a cleaning liquid from a liquid supply system (not shown in the figure) onto the wet cleaning roller 15.

[0045] The suction nozzle 14 is oriented towards the front agitation chamber 12. The suction nozzle 14 is in fluid communication with a suction channel 17; the suction channel 17 can be partially defined by the base body 11 or completely defined by a duct arranged within the base body 11. The suction channel 17 guides the fluids, such as the dirt liquid, debris, and air, sucked through the suction nozzle 14.

[0046] The squeegee member 161 is located within the front agitation chamber 12 closer to the suction nozzle 14 than the liquid distributor 16; in terms of the direction of rotation of the wet cleaning roller 15, the squeegee member 161 is located downstream of the suction nozzle 14, and the liquid distributor 16 is located downstream of the squeegee member 161. The squeegee member 161 is typically a rigid squeegee strip member that abuts the first cleaning element 152 of the wet cleaning roller 15 to remove liquid and debris from the first cleaning element 152 of the wet cleaning roller 15.

[0047] The rear portion 112 includes a rear cover plate 1121 that circumferentially covers the periphery of the partial dry wiping roller 18. The lower portion of the rear agitation chamber 13 has a second lower opening 131. The lower portion of the dry wiping roller 18 is exposed from the second lower opening 131 to contact the surface to be cleaned.

[0048] The dry wiping roller 18 comprises a second roller body 181 defining a rotation axis X2 extending in a horizontal direction, and a second cleaning element 182 covering the outer peripheral side surface of the roller body 181, the second cleaning element 182 being configured to be capable of absorbing a cleaning liquid such as water. The roller diameter D2 of the second roller body 181 is preferably 35-50 mm. In this example, the second cleaning element 182 is preferably a fiber fluff, for example the fluff length L2 of the second cleaning element 182 is 5-15 mm. In other embodiments, the second cleaning element can also be a sponge, a fabric or other types. In some preferred embodiments, in order to increase the liquid absorption performance, the fluff length L2 of the second cleaning element 182 is greater than the fluff length L1 of the first cleaning element 152.

[0049] The cleaning base 1 is further provided with a second motor (not shown in the figure) in driving connection with the dry wiping roller 18 to drive the dry wiping roller 18 to rotate about the rotation axis X2. The first motor and the second motor can be built-in motors built in the corresponding rollers, or can be external motors arranged outside the corresponding rollers. In other possible embodiments, the first motor and the second motor can also be replaced by one motor, i.e. the same motor simultaneously drives the dry wiping roller 18 and the wet cleaning roller 15 to rotate.

[0050] In this example, the roller diameter D2 of the second roller body 181 is preferably less than the roller diameter D1 of the first roller body 151. In the same working process, the wet cleaning roller 15 is driven to rotate at a first angular velocity, and the dry wiping roller 18 is driven to rotate at a second angular velocity greater than the first angular velocity, for example: the first angular velocity is greater than or equal to 6.6π radians per second, and the second angular velocity is greater than or equal to 33π radians per second. In this way, the rotation frequency of the dry wiping roller 18 is as large as possible than the rotation frequency of the wet cleaning roller 15 in the same working process, so that the dry wiping roller 18 can more frequently contact the surface to be cleaned to absorb the residual liquid on the surface to be cleaned. In some preferred embodiments, the second angular velocity can be set to be more than 2 times the first angular velocity.

[0051] The back cover plate 1121 comprises a back top wall 11211 and a back side wall 11212 defining a back portion of the back agitation chamber 13, the back side wall 11212 extending downward from the back edge of the back top wall 11211 and extending below the rotation axis X2 of the dry wiping roller 18. The lower portion of the back side wall 11212 has an arc-shaped section 11213, the bottom edge 11214 of the arc-shaped section 11213 being located below the rotation axis X2, and the inner side surface of the arc-shaped section 11213 being adjacent to the dry wiping roller 18.

[0052] The bottom 114 includes a front end portion 1141 and a rear end portion 1142; the front end portion 1141 defines a rear side boundary of the first lower opening 121, and the rear end portion 1142 defines a front side boundary of the second lower opening 131. In this example, both the front end portion 1141 and the rear end portion 1142 include a flexible scraping strip.

[0053] The dryer 19 is located in the rear agitation chamber 13 and outside the dry wiping roller 18, and is configured to dry the second cleaning element 182 of the dry wiping roller 18. The inner side of the top wall 11211 is provided with a recess 11215, and the dryer 19 is partially accommodated in the recess 11215.

[0054] In this example, the dryer 19 includes a heating body 191 capable of converting electrical energy into heat, and a heat conduction component 192 in thermal conduction connection with the heating body 191. The dryer 19 generates heat through the heating body 191, and then transmits heat to the dry wiping roller 18 outside through the heat conduction component 192. The heat conduction component 192 is preferably a metal element, and the heating body 191 is preferably embedded in the heat conduction component 192.

[0055] The heat conduction component 192 includes an arc-shaped heat surface 1921 extending circumferentially around the rotation axis X2 of the dry wiping roller 18 and circumferentially covering the periphery of part of the second cleaning element 182. In this example, the heat surface 1921 will contact the second cleaning element 182. When the heating body 191 is in heat generation, the heat surface 1921 will continuously transmit heat to the second cleaning element 182, thereby achieving drying of the wet second cleaning element 182.

[0056] The dryer 19 is not limited to the above type, and can also be a dryer containing a quartz tube, a carbon fiber tube, etc. It can also be a dryer including a ceramic heating sheet, etc., as long as it can meet the drying requirement of the rotating dry wiping roller 18.

[0057] In order to reduce heat loss at the dryer 19, a blocking piece 193 is further arranged in the rear agitation chamber 13, and is arranged between the rear end portion 1142 and the dryer 19; the blocking piece 193 is in contact with the dry wiping roller 18; and the blocking piece 193 is preferably made of a hard material. The blocking piece 193 can separate the dryer 19 from the outside. The blocking piece 193 and the arc-shaped section 11213 of the rear side wall 11212 can both prevent heat generated by the dryer 19 from being easily diffused.

[0058] Continuing as Figures 1-2As shown, the handle-body portion 2 comprises a handle 21 and a body 22 arranged on the upper portion. The handle 21 is fixedly connected to the top of the body 22 and is configured to be held by a user. The user can hold the surface cleaner 10 by the handle 21 and move the cleaning base 1 of the surface cleaner 10 back and forth on the surface to be cleaned in a backwardly inclined working position. The handle 21 is further provided with an operation part 211 in signal connection with a control unit (not shown in the figure) for the user to control the operation of the surface cleaner 10. The specific form of the operation part 211 is not limited to a button, a trigger, a trigger, a switch, etc. In other embodiments, the operation part can also be arranged at other places of the surface cleaner, such as on the top wall or side wall of the handle-body portion at the lower portion of the handle. The operation part can also be a portable remote controller or can be arranged on a handheld terminal capable of interacting with the surface cleaner.

[0059] The body 22 can accommodate and carry a plurality of working components on the handle-body portion 2. These plurality of working components include a water supply tank 32 capable of storing and externally providing cleaning liquid. The water supply tank 32 is preferably detachably mounted on the body 22 to facilitate the user to add clean water therein.

[0060] The water supply tank 32 is in fluid communication with the liquid distributor 16 on the cleaning base 1 and forms a liquid supply path (not shown in the figure) for the cleaning liquid to flow. The liquid supply path is further provided with a selectively startable pump (not shown in the figure). By controlling the opening and closing of the pump, the liquid supply to the liquid distributor 16 or the fluid communication between the water supply tank 32 and the liquid distributor 16 can be selectively blocked. The pump can be arranged in the body 22 or in the cleaning base 1. The liquid supply system composed of the water supply tank 32, the water supply path, the pump and the liquid distributor 16 will be able to realize on-demand liquid supply to the wet cleaning roller 15.

[0061] The working components arranged on the body 22 further include a recovery tank 41 capable of receiving and storing dirty liquid and debris and a suction motor 42 arranged on the upper side of the recovery tank 41. The suction nozzle 14 in the cleaning base 1, the recovery tank 41 and the suction motor 42 are in fluid communication in sequence, the suction passage 17 is located between the suction nozzle 14 and the recovery tank 41, and the suction motor 42 is configured to be able to push the fluid containing air to flow from the suction nozzle 14 towards the recovery tank 41 along the recovery flow path. The recovery tank 41 is detachably mounted on the body 22 to facilitate the user to pour the dirty liquid. The recovery system composed of the suction nozzle 14, the suction passage 17, the recovery tank 41 and the suction motor 42 will be able to realize the recovery of the dirty liquid and debris on the surface to be cleaned.

[0062] The body 22 is further provided with a rechargeable battery pack 51, which is electrically connected with the heat-generating body 191 to provide electric energy for the heat generation of the heat-generating body 191.

[0063] In other embodiments, the power supply device of the machine body 22 can also include a power cord that can be electrically connected to a household power socket. The heating body 191 is provided with the electric energy required for heating by the alternating current introduced by the power cord.

[0064] When the surface cleaning machine 10 is in operation, the pump is started, the cleaning liquid in the water supply tank 32 is supplied to the liquid distributor 16 through the liquid supply path and is distributed by the liquid distributor 16 onto the wet cleaning roller 15, the rotating wet cleaning roller 15 wipes the surface to be cleaned with the cleaning liquid, the suction motor 42 is started and a flow of air is formed, the wet cleaning roller 15 carries the dirt liquid and the dirt picked up from the surface to be cleaned into the front agitation chamber 13 along with the flow of air and moves along the recovery flow path 43 towards the suction motor 42, and the dirt liquid and the dirt are finally stored in the recovery tank 41; at the same time, the rotating dry wiping roller 18 is in constant contact with the surface to be cleaned passed by the wet cleaning roller 15, thereby absorbing the liquid remaining on the surface to be cleaned by the second cleaning element 182, the dryer 19 is started to work, and the second cleaning elements 182 of the parts are in constant movement to the dryer 19 in rotation, and the liquid absorbed by the second cleaning elements 182 is heated and evaporated by the heating and drying action of the dryer 19, and the second cleaning elements 182 of the dry wiping roller 18 remain dry and have excellent liquid absorption performance after a long time of use.

[0065] As Figure 8 shown, the cleaning base 8 of this embodiment is similar to the cleaning base 1 described above, and also has a front agitation chamber 82 and a rear agitation chamber 83, and the wet cleaning roller 85 and the dry wiping roller 88 are arranged in the two chambers respectively, and the dryer 89 is located in the rear agitation chamber 83; the difference between the cleaning base 8 and the cleaning base 1 described above is that the rear agitation chamber 83 is in fluid communication with the suction passage 87 through a narrow passage 871, i.e. the fluid in the rear agitation chamber 83 can also be sucked into the suction passage 87. In order not to affect the suction action of the suction nozzle 84, the cross-sectional area of the narrow passage 871 is as small as possible, such as less than or equal to 1 / 2 of the cross-sectional area of the narrowest part of the passage between the front agitation chamber 82 and the suction passage 87.

[0066] The surface cleaning machine scheme of the present application can be applied not only to the upright machine described above, but also to a surface cleaning robot that can autonomously travel and turn on the surface to be cleaned; or to a canister surface cleaning machine.
