As shown in FIG. 1 , an embodiment of the disclosure provides a base 1 for a laundry treatment apparatus. A cleaner 4 is docked in the base 1, and may be configured to automatically clean dust, hair and the like on the ground. In a case that the cleaner 4 is provided with a mop, the cleaner 4 may mop the ground after cleaning the ground. The function of the cleaner of the embodiment of the disclosure does not limit the structure of the base. The functions of the base 1 of the embodiment of the disclosure include, but are not limited to, charging, dust removal, cleaning, drying and disinfection of the cleaner 4.
It should be noted that the base 1 of the embodiment of the disclosure is applied to the laundry treatment apparatus, which may include various forms, such as a washing machine, a spin-dryer and a laundry washer-dryer. The specific application scenario of the laundry treatment apparatus does not limit the structure of the base of the disclosure.
As shown in FIG. 1 and FIG. 2 , the base 1 of the embodiment of the disclosure includes a housing 2 and a dust suction assembly 3. A cleaning cavity 22 for docking the cleaner 4 is arranged inside the housing 2, to realize operations such as the charging and the cleaning of the cleaner 4. Components related to the operations such as the charging and the cleaning of the cleaner 4 are mounted outside the cleaning cavity 22. The dust suction assembly 3 of the embodiment of the disclosure is arranged outside the cleaning cavity 22. In a case that the cleaner 4 is docked in the cleaning cavity 22, the dust suction assembly 3 may suck garbage such as the dust stored in a dust storage space inside the cleaner 4, to vacate the dust storage space inside the cleaner 4, which facilitates the next dust removal operation of the cleaner 4.
As shown in FIG. 3 , the dust suction assembly 3 is provided with a dust collection port 31 adapted to be in communication with the cleaner 4, and the dust collection port 31 is configured to suck the garbage such as the dust stored in the dust storage space of the cleaner 4. The dust suction assembly 3 is further provided with an air return port 32 in communication with the cleaning cavity 22, and the air return port 32 is configured to guide gas in the dust suction assembly 3 to the cleaner 4. As shown in FIG. 2 , the dust storage space for storing the garbage such as the dust is arranged inside the cleaner 4, and a surface of the cleaner 4 is further provided with an inlet and an outlet which are in communication with the dust storage space. In a case that the cleaner 4 is docked in the cleaning cavity 22, the outlet of the cleaner 4 is connected to the dust collection port 31 of the dust suction assembly 3, and the inlet of the cleaner 4 is connected to the air return port 32 of the dust suction assembly 3, to allow the dust storage space of the cleaner 4 and the dust suction assembly 3 to be in communication with each other and to be airtight relative to the exterior of the dust storage space of the cleaner 4 and the dust suction assembly 3. In this way, the gas may form a circulating gas path between the dust storage space of the cleaner 4 and the dust suction assembly 3. That is, the gas may circulate between the dust storage space and the dust suction assembly 3 without flowing to the exterior of the cleaner 4 and the dust suction assembly 3. In addition, the external gas also does not flow to the interior of the cleaner 4 and the dust suction assembly 3.
It should be noted that the communication in the disclosure may be a direct communication, for example, the dust collection port 31 is directly connected to the cleaner 4, to realize the communication. The communication in the disclosure may also be an indirect communication, for example, the dust collection port 31 is in communication with the cleaner 4 through other passages or auxiliary devices.
In the embodiment of the disclosure, the dust collection port 31 of the dust suction assembly 3 is connected to the outlet of the cleaner 4, and the air return port 32 of the dust suction assembly 3 is connected to the inlet of the cleaner 4, to allow the circulating gas path to be formed inside the dust suction assembly 3 and the cleaner 4. The dust suction assembly 3 suctions the dust from the dust storage space of the cleaner 4 through the dust collection port 31, and then the dust suction assembly 3 filters the dust and guides the gas. The gas flows from the dust storage space to the dust suction assembly to generate a pressure difference, to allow a negative pressure to be generated in the dust storage space of the cleaner. The gas filtered by the dust suction assembly flows back to the dust storage space of the cleaner through the air return port under the action of the negative pressure. In this way, an internal circulation for the gas is formed between the dust suction assembly 3 and the cleaner, and the gas continuously passes through the dust storage space and brings the dust in the dust storage space into the dust suction assembly through the dust collection port. The dust suction assembly continuously collects the dust and guides the filtered gas back to the dust storage space. The operations described above are repeated successively until the gas transfers all the dust in the dust storage space to the dust suction assembly, to realize the dust removal of the cleaner by the dust suction assembly.
An embodiment of the disclosure provides a base 1, which includes a housing 2 and a dust suction assembly 3. A cleaning cavity 22 is arranged inside the housing 2. The dust suction assembly 3 is provided with a dust collection port 31 and an air return port 32 which are adapted to be in communication with a cleaner 4, and the dust collection port 31 is configured to suck dust in the cleaner 4. In the embodiment of the disclosure, the dust suction assembly 3 is provided with the dust collection port 31 and the air return port 32, and when the cleaner 4 is docked in the cleaning cavity 22, each of the dust collection port 31 and the air return port 32 is connected to the cleaner 4 to allow a circulation passage to be formed between the dust suction assembly 3 and the cleaner 4. In this way, gas continuously circulates between the dust suction assembly 3 and the cleaner 4, and the dust in the cleaner 4 may be transferred to the dust suction assembly 3 following the circulating gas flow, to realize the dust removal of the cleaner 4. In the technology of improving the structural compactness of the base, the transfer of the dust may be realized by an internal circulation. A circulating gas path between the dust suction assembly and the cleaner has good airtightness, which improves the efficiency of the transfer of the dust. In addition, in the embodiment of the disclosure, the base is applied to a laundry treatment apparatus, which saves a storage space.
In some embodiments, the air return port 32 may be directly connected to the atmosphere, thus the gas in the atmosphere may flow to the air return port 32 and then be blown to the cleaner 4 through the air return port 32. It can be understood that the gas blown to the cleaner through the air return port 32 may be either cleaning gas after the dust is filtered by the dust suction assembly 3, or the gas in the atmosphere.
In some embodiments as shown in FIG. 4 , the structure of the housing is omitted in FIG. 4 for ease of observation. The dust suction assembly 3 includes an intake passage 33, a dust collector 34 and an exhaust passage 35. The intake passage 33 is provided with two opposite ends in an extension direction thereof. One end of the two opposite ends of the intake passage 33 is provided with the dust collection port 31, and another end of the two opposite ends of the intake passage 33 is connected to the dust collector 34. Herein, the intake passage 33 may be provided as a hose, to facilitate the cooperation of the intake passage 33 and other components during assembly. Certainly, the intake passage 33 may also be directly formed by the housing. In some embodiments, a rubber member may be arranged at the dust collection port 31 of the intake passage 33, and the rubber member is arranged around the dust collection port 31. The arrangement of the rubber member may increase the airtightness of the connection between the dust collection port and the cleaner, which improves the efficiency of transferring the dust in the cleaner to the dust collector 34. The dust collector 34 of the embodiment of the disclosure is configured to filter the dust introduced from the dust collection port 31. As shown in FIG. 4 , one end of the exhaust passage 35 is connected to the dust collector 34, and another end of the exhaust passage 35 is provided with the air return port 32. The exhaust passage 35 is configured to guide the gas filtered by the dust collector 34 to the cleaner. In some embodiments, the exhaust passage 35 may be provided as a soft passage, to facilitate the cooperation of the exhaust passage 35 and other components during assembly. A rubber member may be arranged at the air return port 32 of the exhaust passage 35, and the rubber member is arranged around the air return port 32. The arrangement of the rubber member may increase the airtightness of the connection between the air return port and the cleaner, which improves the efficiency of transferring the dust in the cleaner to the dust collector 34.
As shown in FIG. 4 , an internal circulation for the gas is formed between the cleaner 4 and the dust suction assembly 3. The gas passes through the cleaner 4, the dust in the cleaner 4 flows from the intake passage 33 to the dust collector 34 following the gas, and the dust collector 34 may filter the gas passing therethrough. That is, the dust collector 34 collects the dust passing therethrough and guides the gas flowing therethrough, the gas flows from the dust collector 34 to the exhaust passage 35, the gas flows back to the cleaner 4 through the exhaust passage, and then the gas takes away the dust in the cleaner 4 again. The operations described above are repeated successively to realize the transfer of the dust in the cleaner 4 to the dust collector 34. In the embodiment of the disclosure, the dust suction assembly is arranged to include the intake passage, the dust collector and the exhaust passage, the intake passage and the exhaust passage may be easily assembled with other components by cooperating therewith, which reduces the assembly difficulty of the dust collector, improves the space utilization rate of the base and reduces an assembly dimension of the base.
In some embodiments, as shown in FIG. 4 , the dust collection port 31 is closer to the dust collector 34 than the air return port 32. It can be understood that the dust collection port 31 is arranged between the air return port 32 and the dust collector 34, to allow a length of the intake passage 33 to be less than a length of the exhaust passage 35. In the embodiment of the disclosure, the fact that the length of the intake passage 33 is arranged to be shorter shortens a path of the dust flowing from the cleaner to the dust collector 34. In this way, the risk that the dust is left in the intake passage 33 is reduced, the fluency of the intake passage 33 is increased, and the dust suction efficiency of the dust collector is further improved.
In some embodiments, as shown in FIG. 5 , a front end of the cleaning cavity 22 is provided with an opening 221. As shown in FIG. 2 , the opening 221 is in communication with the cleaning cavity 22. It should be noted that the opening 221 refers to an opening with a larger cross-sectional dimension. The opening 221 is arranged at the cleaning cavity 22, to facilitate the movement of the cleaner 4 into the cleaning cavity 22 via the opening 221. The exhaust passage 35 extends from a rear end of the cleaning cavity 22 to a right end of the cleaning cavity 22 and is connected to the dust collector 34. It should be noted that in the embodiment of the disclosure, the front end of the cleaning cavity 22 may be regarded as one end close to the user, and one end away from the user may be regarded as the rear end of the cleaning cavity 22. The intake passage 33 and the dust collector 34 are also arranged at the right end of the cleaning cavity 22.
In the embodiment of the disclosure, the fact that the dust suction assembly is dispersed in two directions by being distributed at the rear end and the right end of the cleaning cavity reduces the dimension of the dust suction assembly in one direction. The side by side arrangement of the dust suction assembly and the cleaning cavity reduces an overall height of the base. The transverse arrangement of the intake passage, the exhaust passage and the dust collector reduces the risk that impurities with high gravity may not be suctioned upward into the dust collector due to a longitudinal arrangement of the intake passage, the exhaust passage and the dust collector, and also reduces the risk that residual dust in the passage (intake passage or exhaust passage) falls out of the passage and into the dust collector when the user takes out the dust collector.
In some embodiments, as shown in FIG. 4 , the intake passage 33 is located between the cleaning cavity 22 and the dust collector 34 in a left-right direction. The intake passage 33 may be provided as a bent-shaped structure, and the intake passage 33 may extend along a front-rear direction. The dust collection port 31 of the intake passage 33 is located at the rear end of the cleaning cavity 22, and the another end of the intake passage 33 is connected to the dust collector 34. The intake passage is arranged to extend substantially along the front-rear direction, which reduces an assembly dimension of the whole dust suction assembly on the premise of meeting the shorter length of the intake passage and improves a structural dimension of the whole base.
In some embodiments, as shown in FIG. 3 , the dust collection port 31 and the air return port 32 are spaced apart from each other in the left-right direction. The spacing means that a distance between the dust collection port 31 and the air return port 32 in the left-right direction is greater than a certain value. The gas enters into the cleaner from the air return port, and then flows to the dust collection port through the cleaner. The dust collection port and the air return port are spaced apart from each other, which increases a flow path of the gas flow in the cleaner. In this way, the gas may take away the dust in the cleaner as much as possible, to reduce the risk of the dust residue in the cleaner, and improve the dust removal efficiency of the cleaner by the dust suction assembly.
In some embodiments, as shown in FIG. 3 , the distance L1 between the dust collection port 31 and the air return port 32 in the left-right direction is greater than 0.5 times a dimension L2 of the cleaning cavity 22 in the left-right direction. In the embodiment of the disclosure, because the dimension of the cleaning cavity in the left-right direction substantially conforms to a dimension of the cleaner, the dimension relationship of the dust collection port, the air return port and the cleaner in the left-right direction may be further defined by defining the relationship of the distance between the dust collection port and the air return port and the dimension of the cleaning cavity, which prolongs the flow path of the gas flow in the cleaner. In this way, the gas may take away the dust in the cleaner as much as possible, to improve the dust removal effect of the cleaner by the dust suction assembly.
In some embodiments, as shown in FIG. 3 , each of the dust collection port 31 and the air return port 32 is arranged at a respective one of two opposite sides of the cleaning cavity 22 in the left-right direction. In the embodiment of the disclosure, the arrangement of each of the dust collection port and the air return port at a respective one of the two opposite sides of the cleaning cavity 22 allows the gas to flow from one side of the cleaner in the left-right direction to another side of the cleaner in the left-right direction. In this way, on the premise of a certain dimension of the cleaning cavity, the flow path of the gas in the cleaning cavity is improved, the efficiency of the gas taking away the dust in the cleaner is improved, and the dust removal effect of the dust suction assembly is improved.
In some embodiments, as shown in FIG. 4 , the dust collector 34 includes a dust collection box 341 and a drive member 342. The dust collection box 341 is connected to the another end of the intake passage 33, herein, the another end of the intake passage 33 refers to one end away from the dust collection port 31. The dust collection box 341 is configured to collect the dust introduced from the intake passage 33 and filter the gas introduced from the intake passage 33. In some embodiments, the another end of the intake passage 33 is connected to a side of the dust collection box 341, in which the side refers to a position of the dust collection box 341 around an up-down direction. The dust collection box 341 is provided with two opposite ends in the up-down direction. In the embodiment of the disclosure, the two opposite ends of the dust collection box 341 in the up-down direction are defined as a top end and a bottom end of the dust collection box, and a part for connecting the top end and the bottom end is defined as the side of the dust collection box. In the embodiment of the disclosure, the manner in which the another end of the intake passage 33 is connected to the side of the dust collection box has the following advantages that the dust in the gas needs to overcome less gravity during the flow thereof, to reduce the risk of the dust accumulation in the intake passage, compared to the manner in which the another end of the intake passage is connected to the top end or the bottom end of the dust collection box.
As shown in FIG. 4 , one end of the drive member 342 is connected to the dust collection box 341, and another end of the drive member 342 is connected to the one end of the exhaust passage 35. The drive member 342 is configured to guide the gas flow to flow from the dust collection port 31 to the air return port 32. The drive member 342 of the embodiment of the disclosure may be configured to disturb the flow of the gas in the intake passage 33 or the exhaust passage 35, to allow the gas to flow from the intake passage 33 to the exhaust passage 35. When the cleaner is connected to the dust suction assembly, the drive member may drive the gas between the cleaner and the dust suction assembly to realize the internal circulation.
In some embodiments, as shown in FIG. 4 , the drive member 342 includes a power supply 3421 and a dust collection motor 3422. The power supply 3421 and the dust collection box 341 are stacked onto one another in the up-down direction. In the embodiment of the disclosure, the up-down direction may be used to refer to a vertical direction in the absolute coordinate system, and a plane formed by the front-rear direction and the left-right direction may be used to refer to a direction of a horizontal plane in the absolute coordinate system. The power supply 3421 of the embodiment of the disclosure may be configured to convert alternating current in the laundry treatment apparatus into direct current, to supply various devices such as the dust collection motor in the base. As shown in FIG. 4 , one end of the dust collection motor 3422 in the front-rear direction is connected to the dust collection box 341, and another end of the dust collection motor 3422 in the front-rear direction is connected to the exhaust passage 35. That is, each of the inlet passage and the exhaust passage is connected to a respective one of two opposite sides of the dust collection motor in the front-rear direction. In the embodiment of the disclosure, the arrangement of the inlet passage, the exhaust passage and the dust collection motor in a horizontal direction reduces the assembly dimension of the base in the vertical direction, and reduces the overall height of the base.
In some embodiments, the dust collection box includes a box body, a drawer and a filter member. A first cavity is arranged inside the box body, and one end of the first cavity in the front-rear direction is provided with an opening. A second cavity in communication with the dust collection port and the air return port is arranged inside the drawer, and the drawer is arranged in the first cavity and movable in translation along the front-rear direction. When the drawer is arranged in the first cavity, the drawer may close the opening, to allow the first cavity and the second cavity to form a sealed cavity. The filter member is arranged in the second cavity, and the filter member is configured to filter the gas passing through the second cavity and collect the dust passing through the second cavity. The filter member is detachably arranged in the second cavity. When the dust in the filter member is full, the filter member may be detached and replaced with a new filter member.
Certainly, in other embodiments, the structure of the dust collection box includes, but is not limited to, the embodiment described above. For example, the dust collection box may be in communication with a drain passage of the laundry treatment apparatus, and water flow in the drain passage passes through the dust collection box and flushes out the dust in the dust collection box to a drain port of the laundry treatment apparatus. In this way, the dust in the dust collection box may be directly discharged to the exterior of the laundry treatment apparatus, the operation of the user is simplified, and the experience of the user is improved.
As shown in FIG. 1 , the base 1 of the embodiment of the disclosure further includes a drying assembly 6. The drying assembly 6 is arranged outside the cleaning cavity. As shown in FIG. 3 , the drying assembly 6 is provided with an air outlet 61 in communication with the cleaning cavity 22. The air outlet 61 is configured to guide the gas flow to the cleaning cavity 22. The gas flow is blown to the cleaning cavity 22 through the air outlet 61, is blown to a wet mop of the cleaner 4 docked in the cleaning cavity 22, and takes away the moisture in the mop to allow the mop to be dried. As shown in FIG. 6 , a portion of the drying assembly 6 is located at an end of the cleaning cavity 22 in the front-rear direction, and another portion of the drying assembly 6 is located at an end of the cleaning cavity 22 in the up-down direction. In the embodiment of the disclosure, the fact that the drying assembly 6 is dispersed in two directions by being distributed at the end of the cleaning cavity in the front-rear direction and the end of the cleaning cavity in the up-down direction reduces the dimension of the drying assembly in one direction. The side by side arrangement of a portion of the drying assembly with the cleaning cavity in the front-rear direction reduces the overall height of the base.
In some embodiments, as shown in FIG. 6 , an end of the cleaning cavity 22 in the front-rear direction is provided with an opening 221, and an end of the cleaning cavity 22 in the up-down direction is regarded as a top end of the cleaning cavity 22. A portion of the drying assembly 6 is arranged at an end of the cleaning cavity 22 in the up-down direction, that is, said portion of the drying assembly 6 is arranged at the top end of the cleaning cavity 22. Another portion of the drying assembly 6 may be arranged at an end of the cleaning cavity 22 in the front-rear direction, that is, the drying assembly 6 may be arranged at the rear end of the cleaning cavity 22. In the embodiment of the disclosure, the distribution of the drying assembly around the cleaning cavity reduces an assembly space of the drying assembly in one direction, and reduces the assembly dimension of the whole base.
In some embodiments, the drying assembly 6 includes a fan 62 and a ventilator 63. The function of the fan 62 is to increase a pressure of the gas by the mechanical energy. Herein, the fan 62 is arranged at an end of the cleaning cavity 22 in the up-down direction, that is, the fan 62 is arranged at the top end of the cleaning cavity 22. As shown in FIG. 6 , one end of the ventilator 63 is in communication with the fan 62, and another end of the ventilator 63 is provided with an air outlet 61 (see FIG. 3 ). The interior of the ventilator 63 is hollow, and the ventilator 63 is arranged at the rear end of the cleaning cavity 22. The ventilator 63 may be configured to guide the gas flow generated by the fan 62 and guide the gas flow in the fan 62 to the cleaning cavity 22. In the embodiment of the disclosure, the drying assembly is arranged in the form of the fan and the ventilator, the drying assembly does not need to be arranged on one side of the cleaning cavity in a concentrated manner, and the drying assembly may be distributed on different sides of the cleaning cavity, which reduces the overall height of the base and reduces the assembly difficulty of the drying assembly.
In some embodiments, as shown in FIG. 6 , a dimension of the fan 62 in the front-rear direction is greater than a dimension of the fan 62 in the up-down direction. In the normal use state of the fan, the dimension of the fan 62 in the vertical direction is greater than the dimension of the fan 62 in the horizontal direction. The fan 62 of the embodiment of the disclosure is arranged horizontally, that is, the dimension of the fan 62 in the vertical direction is less than the dimension of the fan 62 in the horizontal direction, which reduces a space occupied by the fan in the vertical direction and reduces a dimension of the base in the vertical direction.
In some embodiments, as shown in FIG. 6 , an extension direction of the ventilation member 63 is parallel to the up-down direction. It should be noted that the extension direction of the ventilator 63 refers to a length direction of the ventilator 63. The coincidence of the length direction of the ventilator with the up-down direction reduces a space occupied by the ventilator in the front-rear direction, improves the assembly compactness of various components inside the housing, and improves the space utilization rate of the housing.
In some embodiments, as shown in FIG. 6 , a plurality of ventilators 63 are provided. An upper end of each of the plurality of ventilators 63 is in communication with the fan 62, that is, the gas flow generated by the fan 62 is dispersed to the plurality of ventilators 63. Lower ends of the plurality of ventilators 63 are spaced apart from each other in the left-right direction. The gas flow is blown from the another end of each of the plurality of ventilators 63 to the cleaning cavity, to allow the gas flow to be blown to the different positions of the cleaner 4, and to improve the drying efficiency of the cleaner.
In some embodiments, as shown in FIG. 6 , the plurality of ventilators 63 include a first ventilator 631 and a second ventilator 632. One end of the first ventilator 631 is in communication with the fan 62, and another end of the first ventilator 631 is a first air outlet 611. One end of the second ventilator 632 is in communication with the fan 62, and another end of the second ventilator 632 is a second air outlet 612. In some embodiments, the cleaner 4 may be provided with two mops, and the two mops are arranged side by side in the left-right direction. As shown in FIG. 3 , in the embodiment of the disclosure, a distance L3 between the first air outlet 611 and the second air outlet 612 in the left-right direction is greater than or equal to a first dimension and less than or equal to a second dimension. The first dimension is 0.2 times the dimension L2 of the cleaning cavity 22 in the left-right direction, and the second dimension is 0.6 times the dimension L2 of the cleaning cavity in the left-right direction. In the embodiment of the disclosure, the distance between the first air outlet and the second air outlet is defined in a certain range, to allow the gas flow derived from the first air outlet and the second air outlet to be evenly blown to the mops of the cleaner, and to improve the drying efficiency of the cleaner. In some embodiments, as shown in FIG. 6 , the first air outlet 611 and the second air outlet 612 are symmetrically arranged with respect to a center line of the cleaning cavity 22 in the left-right direction. In the embodiment of the disclosure, the symmetrical arrangement of the first air outlet and the second air outlet in the left-right direction improves the drying efficiency of the gas flow to the cleaner in the cleaning cavity.
In some embodiments, as shown in FIG. 6 , a portion of the first ventilator 631 close to the fan 62 extends along the left-right direction, and a portion of the first ventilator 631 close to the first air outlet 611 extends along the up-down direction. A portion of the second ventilator 632 close to the fan 62 extends along the left-right direction, and a portion of the second ventilator 632 close to the second air outlet 612 extends along the up-down direction. That is, one end of the first ventilator 631 close to the fan 62 and one end of the second ventilator 632 close to the fan 62 are connected to the fan 62 and extend along the horizontal direction. A portion of the first ventilator 631 away from the fan 62 and a portion of the second ventilator 632 away from the fan 62 are spaced apart from each other in the left-right direction and extend along the up-down direction. In this way, the first air outlet 611 and the second air outlet 612 are spaced apart from each other in the left-right direction, and the one end of the first ventilator 631 is in communication with the one end of the second ventilator 632, to allow the gas flow to be dispersed and guided to a bottom of the cleaning cavity, to allow the gas flow to be evenly dispersed to the positions of the two mops of the cleaner, and to improve the drying efficiency of the cleaner.
In some embodiments, as shown in FIG. 3 , the air outlet 61 is close to the bottom end of the cleaning cavity 22 in the up-down direction. The up-down direction may refer to the vertical direction of the base in the normal use state, and a lower end shown in FIG. 3 refers to the bottom end of the cleaning cavity 22. It should be noted that the expression “close to” in the embodiment of the disclosure means that a distance between the air outlet 61 and the bottom end of the cleaning cavity 22 is less than or equal to 0.4 times a dimension of the cleaning cavity 22 in the up-down direction. In the embodiment of the disclosure, the arrangement of the air outlet close to the bottom end of the cleaning cavity in the up-down direction reduces a distance between the air outlet and the mop of the cleaner and allows wind derived from the air outlet to be directly blown to the mop. In this way, the dissipation of the gas flow is reduced, and the drying efficiency of the cleaner is further improved.
In some embodiments, the drying assembly also includes a heating member. The heating member is arranged in the ventilator, and the heating member is configured to heat the gas flow passing through the ventilator. The gas flow is heated by the heating member, to allow the temperature of the gas flow to increase. When the gas flow at the high temperature is blown to a surface of the mop of the cleaner, the gas flow at the high temperature conducts heat with the mop, to allow the temperature of the mop to increase, and to accelerate the evaporation of the moisture in the mop. The moisture in the mop is taken away by the air flow, to realize the rapid drying of the mop.
An embodiment of the disclosure also provides a laundry treatment apparatus, which includes a body 5 and the base 1 according to any one of the above embodiments, as shown in FIG. 7 . The body 5 is configured to perform operations such as soaking, washing and drying the laundry, and the base 1 is arranged at one end of the body 5 in the up-down direction. Herein, the up-down direction represents the vertical direction in the absolute coordinate system, that is, the base 1 is arranged at a bottom of the laundry treatment apparatus. When the laundry treatment apparatus is placed on the ground, the base 1 is closer to the ground than the body 5, to allow the cleaner to be moved into the cleaning cavity 22 through the opening.
What described above are merely preferable embodiments of the disclosure, and are not intended to limit the scope of protection of the disclosure.
