Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.

The embodiment of the application provides a base assembly and a clothes dryer. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

Firstly, the embodiment of the application provides a base assembly, which comprises a chassis, wherein a collecting tank, a drainage pump mounting groove and a drainage groove are arranged on the chassis, and the drainage groove is communicated with the collecting tank and the drainage pump mounting groove so that water in the collecting tank flows into the drainage pump mounting groove; the bottom surface of the drainage pump mounting groove is at least partially sunken to form a water collecting area.

Fig. 1 is a schematic structural diagram of a base assembly according to an embodiment of the present disclosure, and as shown in fig. 1, the base assembly 100 includes a base plate 110, a collecting tank 120 is disposed on the base plate 110, and the collecting tank 120 is used for collecting water flowing into the base plate 110, such as condensed water formed by condensing hot air.

The chassis 110 is further provided with a drain pump mounting groove 140 for mounting a drain pump, the drain pump mounting groove 140 is communicated with the collecting tank 120, so that water in the collecting tank 120 flows into the drain pump mounting groove 140 and is discharged through the drain pump, thereby avoiding accumulated water in the collecting tank 120 or the drain pump mounting groove 140, and the accumulated water may cause generation of odor for a long time.

Optionally, a drainage groove 130 is further disposed between the collection groove 120 and the drain pump installation groove 140, and water in the collection groove 120 is drained through the drainage groove 130 and then flows into the drain pump installation groove 140. The arrangement of the drainage groove 130 enables the water in the collection groove 120 to flow out in a directional manner, so that the structure and position of the drainage pump installation groove 140 can be designed and adjusted according to actual manufacturing requirements without being limited by the structure of the collection groove 120.

Wherein, drainage groove 130 can be the long and narrow circulation passageway, also can be the drainage hole that sets up on collecting vat 120 and drain pump mounting groove 140 intercommunication face, and its concrete structure can be adjusted according to actual design demand, only need can satisfy the water in the collecting vat 120 introduce in the drain pump mounting groove 140 can.

It should be noted that, in the embodiment of the present application, the collecting tank 120, the drainage groove 130, and the drainage pump mounting groove 140 can be manufactured in an integrated manner, or can be formed separately, and then assembled together, only the communication relationship among the collecting tank 120, the drainage groove 130, and the drainage pump mounting groove 140 needs to be satisfied, which is not limited herein.

Alternatively, the bottom surface of the drain pump mounting groove 140 is at least partially recessed to form the water collecting area 141, i.e., the bottom surface of the drain pump mounting groove 140 is not at the same water level, but is formed with the water collecting area 141 having a lower water level, so that the water flowing from the collecting tank 120 into the drain pump mounting groove 140 through the drainage groove 130 can further flow into the water collecting area 141 having a lower water level, thereby further facilitating the drain pump to drain the water in the collecting tank 120 and the drain pump mounting groove 140, and avoiding the water accumulation in the bottom chassis 110 of the base assembly 100.

Optionally, the depth of the recess of the water collecting area 141 at the bottom of the drain pump mounting groove 140 is greater than or equal to 3mm, and the depth of the recess of the water collecting area 141 directly affects whether the water in the drain pump mounting groove 140 can effectively flow into the water collecting area 141. In the manufacturing process of the bottom surface of the drain pump mounting groove 140, the bottom surface of the drain pump mounting groove 140 may have a small concave curvature due to the influence of the processing precision.

If the depth of the water collection area 141 is too small, the water in the drain pump mounting groove 140 cannot be effectively introduced into the low water level water collection area 141, and thus the water in the drain pump mounting groove 140 cannot be effectively discharged. Therefore, in the embodiment of the present application, the depth of the water collection area 141 can be set to be greater than or equal to 3mm, for example, the depth of the water collection area 141 can be set to be 3mm, 4mm, or 5mm, and the specific depth of the water collection area can be adjusted according to actual design requirements, and it is only necessary to ensure that the water in the drainage pump installation groove 140 can be concentrated in the water collection area 141.

Alternatively, the bottom surface of the sump 141 of the drain pump mounting groove 140 can be provided as a concave curved surface. When the water flows from the collecting tank 120 into the drain pump mounting groove 140 and then flows into the water collecting region 141, if the bottom surface of the water collecting region 141 is a flat surface, there is a risk that the water cannot be completely drained during the drainage process, and the water is accumulated in the water collecting region 141. In the embodiment of the present application, the bottom surface of the water collecting area 141 is set to be the concave curved surface, so that the water flowing into the water collecting area 141 is collected to the lowest point of the concave curved surface in the discharging process, thereby avoiding the accumulation of the water at the corner or other places of the water collecting area 141, and reducing the risk of water accumulation in the water collecting area 141.

The bottom surface of the water collection area 141 may be inclined in addition to the concave curved surface, and the inclination direction may be such that the height of the bottom surface gradually decreases from the periphery of the bottom surface of the water collection area 141 to the bottom surface of the middle area of the bottom surface, thereby forming the lowest point of the water level in the middle area. Of course, the bottom surface of the water collecting area 141 can be set to other types of structures, so that it is only necessary to ensure that the bottom surface of the water collecting area 141 can further form the lowest point of the water level, which is helpful for draining the water in the water collecting area 141, so that the water collecting area 141 does not generate the water accumulation condition.

Alternatively, the drain pump mounting groove 140 in the embodiment of the present application has a first sidewall 142 and a second sidewall 143 disposed opposite to each other, and the drainage groove 130 penetrates the first sidewall 142. That is, the drain pump mounting groove 140 is not completely open and directly communicates with the drain groove 130, but the drain groove 130 passes through the first sidewall 142 of the drain pump mounting groove 140 and forms a drain hole on the first sidewall 142, thereby achieving communication between the drain pump mounting groove 140 and the drain groove 130.

When the water amount in the collecting tank 120 is too large, the first sidewall 142 is disposed to block water, so that the collecting tank 120 has a corresponding water storage capacity, and the water in the collecting tank 120 can slowly flow into the first sidewall 142 through the drainage hole formed in the drainage groove 130, rather than directly flowing into the drainage pump mounting groove 140 from the drainage groove 130, and may even directly overflow the drainage pump mounting groove 140 and enter other structures, thereby causing water accumulation in other places of the base plate 110.

When the water in the collection tank 120 flows into the drain pump installation groove 140, if the drainage speed of the drain pump is lower than the inflow speed of the water, the water level in the drain pump installation groove 140 gradually increases, and even overflows out of the drain pump installation groove 140. At this time, the second sidewall 143 enables the drain pump mounting groove 140 to have a sufficient water storage capacity, so as to prevent water from overflowing into other structures due to the increase of the water level in the drain pump mounting groove 140, thereby causing water accumulation in the bottom plate 110 of the base assembly 100.

The heights of the first side wall 142 and the second side wall 143 can be designed and adjusted according to actual requirements, and it is only necessary to ensure that the first side wall 142 can satisfy the water storage capacity of the collecting tank 120 and the second side wall 143 can satisfy the water storage capacity of the drainage pump mounting groove 140, so that water is prevented from overflowing to other structures, and the chassis 110 is prevented from generating accumulated water.

It should be noted that the drainage groove 130 penetrates the first sidewall 142 such that the drainage groove 130 forms a drainage hole on the first sidewall 142 having a lower edge height higher than or equal to the bottom surface height of the drainage pump mounting groove 140. The lower edge height that sets up the drainage hole in this application embodiment is higher than the bottom surface height of drain pump mounting groove 140 to make and form the difference in height between drainage groove 130 and the drain pump mounting groove 140, can reduce the water that flows into in drain pump mounting groove 140 and flow back to drainage groove 130 even in collecting vat 120 again, avoid the unable production that causes ponding of discharging completely of water in the chassis 110.

Alternatively, in the embodiment of the present application, the drain pump mounting groove 140 has a first edge 144 and a second edge 145 opposite to each other, wherein the first edge 144 and the second edge 145 are sequentially distributed in a direction away from the collecting tank 120, and the drainage groove 130 extends from the collecting tank 120 to the first edge 144 to communicate with the drain pump mounting groove 140, i.e., the water in the collecting tank 120 directly flows into the drain pump mounting groove 140 through the first edge 144 via the drainage groove 130, then flows into the water collecting area 141 from the drain pump mounting groove 140, and is drained by the drain pump.

In some embodiments, the water collecting area 141 of the bottom surface of the drain pump mounting groove 140 extends from the first edge 144 toward the second edge 145, and the water collecting area 141 is directly abutted to the drainage groove 130, i.e., the water in the collection groove 120 directly flows into the water collecting area 141 through the drainage groove 130 without flowing into the drain pump mounting groove 140 first, which can reduce the problem of water accumulation on the bottom surface of the drain pump mounting groove 140 caused by the water flowing into the drain pump mounting groove 140 first and the water in the drain pump mounting groove 140 can not completely flow into the water collecting area 141.

When the water collecting area 141 extends from the first edge 144 to the second edge 145, the water collecting area 141 can only extend for a certain distance and can also directly extend to contact with the second edge 145, that is, the water collecting area 141 can span the first edge 144 and the second edge 145 of the drainage pump mounting groove 140, the specific extending distance can be adjusted according to actual design requirements, and only the requirement that the water collecting area 141 can effectively collect water in the drainage pump mounting groove 140 is required.

It should be noted that the drain pump mounting groove 140 further has a third edge 146 and a fourth edge 147 disposed opposite to each other, and the third edge 146 and the fourth edge 147 are located between the first edge 144 and the second edge 145, that is, the first edge 144, the second edge 145, the third edge 146, and the fourth edge 147 jointly enclose the sides of the drain pump mounting groove 140.

Wherein, after extending a distance from the first edge 144 toward the second edge 145, the water collecting area 141 can extend toward the third edge 146 and the fourth edge 147 to contact with the third edge 146 and the fourth edge 147, respectively, that is, the water collecting area 141 is in contact with the drainage groove 130 and spans the third edge 146 and the fourth edge 147. This kind of structural design can reduce the machining precision demand to catchment area 141 and drainage groove 130 relative position, avoids because machining error makes drainage groove 130 or catchment area 141's actual position produce the deviation to lead to catchment area 141 can't realize with drainage groove 130's direct butt joint, reduced preparation precision demand and technology degree of difficulty.

Alternatively, the height of the bottom surface of the drain pump mounting groove 140 with respect to the bottom surface of the sump 141 in the embodiment of the present application is gradually increased in a direction away from the sump 141. That is, the bottom surface of the drain pump mounting groove 140 is inclined, so that the water flowing from the collecting tank 120 into the drain pump mounting groove 140 can completely flow into the water collecting area 141, which is beneficial to completely discharging the water in the drain pump mounting groove 140, and avoids water accumulation on the chassis 110.

When the sump 141 is located in the middle of the drain pump mounting groove 140, the height of the bottom surface of the drain pump mounting groove 140 relative to the bottom surface of the sump 141 gradually increases from the vicinity of the sump 141 to the first edge 144, the second edge 145, the third edge 146, and the fourth edge 147, so that the heights of the bottom surfaces of the drain pump mounting grooves 140 around the sump 141 are gradually increased.

When the sump 141 spans the first and second edges 144 and 145, the height of the bottom surface of the drain pump mounting groove 140 with respect to the bottom surface of the sump 141 gradually increases from near the sump 141 to the third and fourth edges 146 and 147, respectively; when the sump 141 spans the third and fourth edges 146 and 147, the height of the bottom surface of the drain pump mounting groove 140 with respect to the bottom surface of the sump 141 gradually increases from near the sump 141 toward the first and second edges 144 and 145, respectively. That is, no matter where the sump 141 is located in the sump mounting groove 140, it is only necessary to ensure that the height of the bottom surface of the sump mounting groove 140 relative to the bottom surface of the sump 141 is gradually increased along the direction away from the sump 141, so that the water flowing from the collecting tank 120 into the sump mounting groove 140 does not form accumulated water in the sump mounting groove 140 due to the water failing to flow into the sump 141.

It should be noted that the height of the bottom surface of the drain pump mounting groove 140 with respect to the bottom surface of the water collecting region 141 is gradually increased in a direction away from the water collecting region 141, wherein the gradual increase can be a uniform increase, that is, the bottom surface of the drain pump mounting groove 140 is inclined in a direction away from the water collecting region 141, so that the water in the drain pump mounting groove 140 flows into the water collecting region 141 along the inclined surface without accumulating in the drain pump mounting groove 140. The specific inclination angle can be adjusted correspondingly according to actual requirements, and the adjustment is not limited here.

In some embodiments, the height of the bottom surface of the drain pump mounting groove 140 relative to the bottom surface of the water collection area 141 can also be increased unevenly in a direction away from the water collection area 141, for example, the bottom surface of the drain pump mounting groove 140 can be curved in a direction away from the water collection area 141, so that the water in the drain pump mounting groove 140 flows into the water collection area 141 along the curved surface without forming accumulated water in the drain pump mounting groove 140.

In other embodiments, the height of the bottom surface of the drain pump mounting groove 140 relative to the bottom surface of the water collection area 141 can be increased in a stepwise manner along the direction away from the water collection area 141, that is, the bottom surface of the drain pump mounting groove 140 is a plurality of continuous inclined planes with different inclination angles along the direction away from the water collection area 141, and the inclination angles can be gradually increased along the direction away from the water collection area 141, so that the water in the drain pump mounting groove 140 gradually flows into the water collection area 141 along the inclined planes, which helps to avoid splashing caused by too fast water flow rate, and even water splashed out of the drain pump mounting pump and having other structures.

Optionally, in the embodiment of the present application, the bottom surface of the drain pump mounting groove 140 may be integrally formed as a concave curved surface, that is, the bottom surfaces of the water collecting region 141 and the drain pump mounting groove 140 are integrated, and the lowest point of the concave curved surface is the lowest point of the water level of the water collecting region 141.

In some embodiments, the bottom surface of the drain pump mounting groove 140 can also be formed by connecting a plurality of inclined surfaces to each other by a concave curved surface, so that the height of the bottom surface of the drain pump mounting groove 140 is gradually reduced from the edge to the middle area, which is the water collecting area 141 in the drain pump mounting groove 140.

Alternatively, in the embodiment of the present application, the height of the bottom surface of collection trough 120 relative to the bottom surface of drainage trough 130 increases in a direction away from drainage trough 130. That is, the bottom surface of the collection tank 120 is inclined, so that the water in the collection tank 120 can completely flow into the drain pump installation groove 140, and the water is not accumulated in the collection tank 120, thereby preventing the water accumulation in the bottom plate 110 of the base assembly 100.

The height of the bottom surface of the collecting groove 120 relative to the bottom surface of the drainage groove 130 can be gradually and uniformly increased along the direction away from the drainage groove 130, that is, the bottom surface of the collecting groove 120 is an inclined plane along the direction away from the drainage groove 130, so that the water in the collecting groove 120 flows into the drainage pump mounting groove 140 along the inclined plane without being accumulated in the collecting groove 120. The specific inclination angle can be adjusted correspondingly according to actual requirements, and the adjustment is not limited here.

In some embodiments, the height of the bottom surface of collection trough 120 relative to the bottom surface of drainage trough 130 can also increase non-uniformly in a direction away from drainage trough 130, e.g., the bottom surface of collection trough 120 can be curved in a direction away from drainage trough 130, such that water within collection trough 120 flows along a curved surface into drain pump mounting trough 140 without forming a pool of water within collection trough 120.

In other embodiments, the height of the bottom surface of the collecting tank 120 relative to the bottom surface of the drainage groove 130 can be increased in a step manner along the direction away from the drainage groove 130, that is, the bottom surface of the collecting tank 120 is a plurality of continuous inclined planes with different inclination angles along the direction away from the drainage groove 130, and the inclination angles can be set to be gradually increased along the direction away from the drainage groove 130, so that the water in the collecting tank 120 gradually slows down when flowing into the drainage pump mounting groove 140 along the inclined planes, which helps to avoid splashing due to too fast water flow rate, and even water splashed out of the collecting tank 120 and having other structures.

Alternatively, in the embodiment of the present application, the height of the bottom surface of the drainage groove 130 is gradually increased in a direction away from the drain pump mounting groove 140. That is, the bottom surface of the drainage groove 130 is inclined, which is beneficial to the water in the collecting groove 120 flowing into the drainage pump mounting groove 140, so as to prevent the water in the collecting groove 120 from not completely flowing into the drainage pump mounting groove 140 and forming accumulated water in the drainage groove 130.

Wherein, the height of the bottom surface of the drainage groove 130 can be gradually and uniformly increased along the direction away from the drainage pump mounting groove 140, that is, the bottom surface of the drainage groove 130 is an inclined plane along the direction away from the drainage pump mounting groove 140, so that the water in the collecting groove 120 flows into the drainage pump mounting groove 140 along the inclined plane without accumulating in the drainage groove 130. The specific inclination angle can be adjusted correspondingly according to actual requirements, and the adjustment is not limited here.

In some embodiments, the height of the bottom surface of the drainage groove 130 can also increase non-uniformly in a direction away from the drain pump mounting groove 140, for example, the bottom surface of the drainage groove 130 can be curved in a direction away from the drain pump mounting groove 140, such that water in the collection groove 120 flows into the drain pump mounting groove 140 along the curved surface without forming stagnant water within the drainage groove 130.

In other embodiments, the height of the bottom surface of the drainage groove 130 can be increased in a stepwise manner along the direction away from the drainage pump mounting groove 140, that is, the bottom surface of the drainage groove 130 is a plurality of continuous inclined planes with different inclination angles along the direction away from the drainage pump mounting groove 140, and the inclination angle can be set to be gradually increased along the direction away from the drainage pump mounting groove 140, so that the water in the collecting tank 120 gradually slows down when flowing into the drainage pump mounting groove 140 from the drainage groove 130, which helps to avoid splashing due to too fast water flow rate, and even water of other structures caused by splashing out of the drainage groove 130.

Secondly, the embodiment of the present application further provides a clothes dryer, which includes a base assembly, and the specific structure of the base assembly refers to the above embodiments, and since the clothes dryer adopts all the technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved. And will not be described in detail herein.

Fig. 2 is a schematic diagram illustrating an internal structure of a clothes dryer according to an embodiment of the present disclosure, and as shown in fig. 2, the clothes dryer includes a base assembly 100, an evaporator 200, and a drain pump 300. The evaporator 200 is used for rapidly cooling the hot water vapor of the clothes in the clothes dryer to form condensed water, and then discharging the condensed water into the base assembly 100. The drain pump 300 is used to drain the condensed water in the base assembly 100, thereby achieving the purpose of draining the dried clothes.

Optionally, the dryer includes a water-stop sheet 150, and the water-stop sheet 150 is installed above the collecting tank 120 in the base assembly 100 and is used for covering the opening on the collecting tank 120. Evaporator 200 then installs on water-stop sheet 150, and corresponds with the position of collecting vat 120, and the comdenstion water that evaporator 200 formed flows into in collecting vat 120 through water-stop sheet 150, and water-stop sheet 150's setting can avoid the comdenstion water in the collecting vat 120 to cause adverse effect to evaporator 200, also can play the bearing effect to evaporator 200 simultaneously.

Optionally, the clothes dryer includes a water level sensor 400, the water level sensor 400 is installed in the drain pump installation groove 140 of the base assembly 100, and is configured to detect whether there is accumulated water in the drain pump installation groove 140, if there is accumulated water, send a drain signal to the drain pump 300, and the drain pump 300 drains the water in the drain pump installation groove 140.

It should be noted that the water level sensor 400 can also be directly installed in the water collecting area 141 of the drain pump installation groove 140, so that the monitoring result of the water level sensor 400 is closer to the water accumulation condition at the lowest water level of the chassis 110, and the water in the drain pump installation groove 140 is prevented from being drained and remaining in the water collecting area 141, thereby causing the water accumulation in the water collecting area 141.

Optionally, the dryer further includes a mounting bracket 500, the water level sensor 400 is mounted on the mounting bracket 500, and then the mounting bracket 500 is mounted on the drain pump mounting groove 140, so that the connection between the water level sensor 400 and the drain pump mounting groove 140 is facilitated.

It should be noted that the drain pump 300 can also be mounted on the mounting bracket 500 together with the water level sensor 400, the drain pump 300 and the mounting bracket 500 are integrated and then mounted in the drain pump mounting groove 140, and the mounting bracket 500 can support the drain pump 300, so that the gravity of the drain pump 300 is prevented from acting on the bottom surface of the drain pump mounting groove 140, and the service life of the drain pump mounting groove 140 is prolonged.

Alternatively, the drain pump 300 may be directly installed above the water collecting region 141 of the drain pump mounting groove 140, and an inlet of the drain pump 300 is located in the water collecting region 141, so that a pumping pipe of the drain pump 300 extends into the water collecting region 141, thereby achieving effective drainage of water in the water collecting region 141. The drain pump 300 can contact with the bottom surface of the drain pump mounting groove 140, and can also leave a gap with the bottom surface of the drain pump mounting groove 140, and the design can be adjusted according to the actual use situation.

When the drain pump 300 directly contacts the bottom surface of the drain pump mounting groove 140, in order to ensure that the water in the drain pump mounting groove 140 can normally flow into the water collecting area 141, the lower end surface of the drain pump 300 cannot completely cover the opening area of the water collecting area 141, i.e., a circulation gap needs to be left, so as to ensure the normal operation of the drainage process. In the embodiment of the present application, it is possible to directly design the sump area 141 to extend from the first edge 144 toward the second edge 145 of the drain pump mounting groove 140 and to be connected with the second edge 145, i.e., the sump area 141 spans the first edge 144 and the second edge 145 of the drain pump mounting groove 140. The lower end surface of the drain pump 300 is designed to be circular, so that the water in the drain pump mounting groove 140 can be ensured to normally flow into the water collecting area 141 no matter where the drain pump 300 is located in the water collecting area 141, thereby ensuring a normal drainage process of the drain pump 300.

When a gap is left between the drain pump 300 and the bottom surface of the drain pump mounting groove 140, the entire weight of the drain pump 300 is applied to the side surface of the drain pump mounting groove 140, and a material with high strength is selected when the drain pump mounting groove 140 is manufactured, so that the drain pump mounting groove 140 is not damaged in a long-term use process, and the service life of the clothes dryer is prolonged.

Optionally, the clothes dryer further includes a drain pipe 600 and a water storage box 800, two ends of the drain pipe 600 are respectively connected to the drain pump 300 and the water storage box 800, when draining, the water in the water collecting area 141 is pumped out by the water pumping pipe of the drain pump 300, and the water is drained into the water storage box 800 through the drain pump 300 and the drain pipe 600, wherein the water storage box 800 can be directly communicated with the outside, so that the water is drained out of the clothes dryer, and further the purpose of drying and draining is achieved.

Optionally, the dryer is further provided with a water tank 900, the water storage box 800 is installed in the water tank 900, when the pumping speed of the drainage pump 300 is greater than the drainage speed of the water storage box 800, the water in the water storage box 800 may overflow, and the water tank 900 may be used as a transition container to temporarily collect the water overflowing from the water storage box 800, so as to prevent the water from directly flowing into other structures of the dryer, and thus the water is accumulated in the dryer or a fault occurs in the dryer.

Optionally, the dryer further includes a water return pipe 700, one end of the water return pipe 700 is inserted into the drain pump installation groove 140, and the other end of the water return pipe 700 is inserted into the water tank 900, when the water in the water storage box 800 overflows into the water tank 900 without being discharged, the water in the water tank 900 can flow back into the drain pump installation groove 140 through the water return pipe 700, and then the drain pump 300 is pumped into the water storage box 800 again, and the above operation is repeated until all the water in the drain pump installation groove 140 is drained, so as to achieve the purpose of drying and draining. The arrangement of the water return pipe 700 can effectively avoid the problem that the water in the water storage box 800 overflows to the water tank 900 due to the fact that the water drainage speed of the water storage box 800 is smaller than the water pumping speed of the water drainage pump 300, and the water in the water tank 900 cannot be drained in time, and also avoid the problem that the water in the water tank 900 needs to be treated independently, so that the operation convenience of the clothes dryer is improved.

It should be noted that the base assembly 100 in the embodiment of the present application can be used for other household appliances with drying or draining functions, such as a washing machine with drying function, besides the clothes dryer, and is not limited herein.
