Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically to a dehydrator. Background Technology

[0002] A spin dryer is a machine used to dehydrate clothes. It generally consists of a casing, which includes a drum, a bottom shell, and a cover. An impeller is located at the bottom of the drum, and a motor is housed in the bottom shell, driving the impeller to rotate. A water seal is installed at the connection between the motor and the impeller to ensure airtightness. A spin-drying basket is also installed inside the drum, directly mounted on the impeller. Because the basket is mounted on the impeller, it rotates synchronously with the impeller to dehydrate the clothes placed inside.

[0003] In this structure, the impeller not only drives the spin-dry basket to rotate but also supports it. Since the spin-dry basket has a certain weight after clothes are placed inside, the basket pressing against the impeller hinders rapid rotation. Furthermore, the spin-dry basket is only constrained by the impeller at the bottom, and the weight of the clothes is unevenly distributed throughout the basket. During the spin-dry basket's rotation, the impeller cannot effectively constrain it, causing the spin dryer to wobble significantly. Utility Model Content

[0004] The purpose of this invention is to provide a dehydrator that minimizes shaking when dehydrating clothes and makes it easier for the dehydration basket to rotate quickly for dehydration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dehydrator includes a housing, a motor is disposed within the housing, the housing includes a cylinder, a pulsator is disposed at the bottom of the cylinder and is drivenly connected to the motor, a suspension member is disposed at the top of the cylinder, a dehydration basket is rotatably hung on the suspension member, the bottom of the dehydration basket is provided with a first groove that matches a first protrusion on the pulsator, when the dehydration basket is hung on the suspension member, the first groove engages with the first protrusion, so that the pulsator drives the dehydration basket to rotate when it rotates, and the rotation axis of the dehydration basket is collinear with the rotation axis of the pulsator.

[0007] Optionally, the suspension member is detachably mounted on the top of the cylinder.

[0008] Optionally, the suspension component is a suspension rod, and the top of the side wall of the cylinder is provided with two upward-facing placement slots, and the two ends of the suspension rod are respectively engaged in the two placement slots.

[0009] Optionally, the bottom of the dehydration basket is provided with an upwardly concave shell, the lower surface of the concave shell forming the first groove, and the upper surface of the concave shell forming the second protrusion.

[0010] Optionally, the dehydration basket includes an upper basket and a lower basket, which are detachably connected.

[0011] Optionally, the bottom of the upper basket is provided with a first annular convex edge, and the top of the lower basket is provided with a second annular convex edge. The first annular convex edge and the second annular convex edge correspond to each other. A plurality of L-shaped hooks are provided below the first annular convex edge. Each L-shaped hook includes a vertical bar and a horizontal bar. The portion of the first annular convex edge corresponding to the horizontal bar is provided with a first notch. The second annular convex edge is provided with hooking holes matching the number of L-shaped hooks. The L-shaped hooks extend into the hooking holes and, after rotation, hook onto the lower surface of the second annular convex edge. The rotation and hooking direction of the L-shaped hooks is opposite to the rotation direction of the impeller during dehydration.

[0012] Optionally, the suspension member is provided with a shaft hole and a support surface, the dehydration basket is fixedly provided with a rotating shaft, the rotating shaft is provided with an overlapping surface, the rotating shaft is rotatably connected to the shaft hole and the overlapping surface overlaps the support surface, so that the dehydration basket is rotatably hung on the suspension member.

[0013] Optionally, the side wall of the rotating shaft is provided with a second annular groove, and a retaining spring is provided in the second annular groove. The side wall of the shaft hole is provided with a first annular groove, and the retaining spring is provided in the first annular groove. The lower surface of the retaining spring forms the overlapping surface, and the lower surface of the annular groove forms the supporting surface.

[0014] Optionally, a second blind hole is provided in the middle of the suspension member, and a first cap body is interference-connected in the second blind hole. The first cap body is provided with the shaft hole and the support surface.

[0015] Optionally, a suction cup is provided at the bottom of the housing.

[0016] The technical solution of this utility model involves installing a suspension component at the top of the dewatering machine's cylinder. The dewatering basket is rotatably hung on the suspension component, providing upward support to the basket and reducing or eliminating the supporting force exerted by the impeller on it. Furthermore, the suspension component constrains the top of the basket, ensuring that both the top and bottom are restrained during rotation, thus reducing swaying during rotation. Simultaneously, since the basket no longer exerts downward pressure on the impeller, it can more effectively output rotation, thereby facilitating the rapid rotation of the dewatering basket.

Detailed Implementation

[0027] The embodiments will now be described with reference to the accompanying drawings. See also Figure 1-9 This utility model provides a dehydrator, see [link to utility model]. Figure 1 and Figure 8 The system includes a housing 1, which may include a cylindrical body 11, a bottom shell 12 disposed below the cylindrical body 11, and a cap 13 covering the opening of the cylindrical body 11. A motor is disposed within the bottom shell 12. See also... Figure 3 A pulsator 2 is installed at the bottom of the inner cylinder 11, and the pulsator 2 is connected to the motor drive. To ensure sealing, a water seal is installed at the connection between the motor and the pulsator. Both the drive connection between the pulsator 2 and the motor, and the water seal, can be existing structures. See [reference needed]. Figure 2The top of the cylinder 11 is equipped with a suspension member 4, on which a dehydration basket 3 is rotatably hung. This means the dehydration basket 3 is suspended from the suspension member 4 and can rotate around a vertical axis. The suspension member 4 provides upward support to the dehydration basket 3. (See also...) Figure 3 The bottom of the spin-dry basket 3 is provided with a first groove that matches the first protrusion on the impeller 2. When the spin-dry basket 3 is hung on the suspension member 4, the first groove and the first protrusion engage. This engagement means that the sidewall of the first groove contacts the sidewall of the first protrusion, while the top wall of the first groove and the top wall of the first protrusion may or may not contact each other. This allows the impeller 2 to rotate, driving the spin-dry basket 3 to rotate, with the axis of rotation of the spin-dry basket 3 collinear with the axis of rotation of the impeller 2. It should be noted that due to manufacturing errors, after the spin-dry basket 3 is suspended on the suspension member 4 and clothes are placed inside, the bottom of the spin-dry basket 3 may come into contact with the impeller 2, and the impeller 2 may provide some upward support to the spin-dry basket 3. However, the preferred structure is that the impeller 2 does not provide upward support to the spin-dry basket 3; the spin-dry basket 3 mainly relies on the support of the suspension member 4 to counteract gravity. This ensures that the impeller 2 only provides rotational force to the spin-dry basket 3. Thus, firstly, during dehydration, the impeller 2 provides only a small or no support force to the dehydration basket 3, primarily offering rotational force in the planar direction. The impeller 2 can drive the dehydration basket 3 to rotate rapidly. Secondly, in addition to being constrained at the bottom by the impeller 2, the dehydration basket 3 is also constrained at the top by the suspension component 4; that is, the dehydration basket 3 is constrained at both the top and bottom, resulting in less swaying during dehydration.

[0028] In this invention, during the dehydration process, the dehydration basket 3 is placed inside the cylinder 11, and the clothes are placed inside the dehydration basket 3 for dehydration.

[0029] Optionally, the suspension component 4 is detachably mounted on the top of the cylinder 11, and the dewatering basket 3 and the impeller 2 are detachably connected for transmission.

[0030] Thus, after the clothes have finished spinning, the hanging piece 4, the spin-drying basket 3, and the clothes can be removed from the drum 11 and moved to the clothes rack position. Then, the clothes can be taken out of the spin-drying basket 3. Conversely, the clothes to be spun can be placed in the spin-drying basket 3 first, and then the hanging piece 4, the spin-drying basket 3, the clothes, and the drum 11 can be spun or washed. This eliminates the need for a special container for clothes and makes it easier to take clothes out of the spin-drying basket 3.

[0031] Optionally, see Figure 2 and Figure 3 The suspension component 4 is a suspension rod. The top of the cylinder 11 is provided with two upward-facing placement slots 111, and the two ends of the suspension rod are respectively engaged in the two placement slots 111.

[0032] This structure is relatively simple to manufacture and makes it easy to remove the suspension component 4 and the dehydration basket 3 together from the cylinder 11; they can be removed simply by lifting them upwards. It also makes it easy to place the suspension component 4 and the dehydration basket 3 together into the cylinder 11.

[0033] Optionally, see Figure 3 and Figure 7 The bottom of the dehydration basket 3 is provided with a concave shell 321, which is formed by the upward indentation of the bottom of the dehydration basket 3. The lower surface of the concave shell 321 forms a first groove that engages with the first protrusion on the impeller 2. The upper surface of the concave shell 321 forms a second protrusion, and the shape of the second protrusion can be the same as or similar to the shape of the first protrusion on the impeller 2.

[0034] In this way, the dehydration basket 3 can be adapted to existing impellers, and when the dehydration basket 3 rotates, the concave shell 321, due to the presence of the second protrusion, can achieve a water stirring effect similar to that of the impeller.

[0035] Optionally, see Figure 3 and Figure 7 The dehydration basket 3 includes an upper basket 31 and a lower basket 32, which are detachably connected.

[0036] This further facilitates the loading and unloading of clothes. For example, the upper half of the basket 31 can be removed first, clothes can be placed into the lower half of the basket 32, and then the upper half of the basket 31 can be installed into the lower half of the basket 32 ​​before adding more clothes. Alternatively, some clothes can be removed first, then the upper half of the basket 31 can be removed, and then more clothes can be removed. This is because the spin-drying basket 3 needs to be rotated and hung on the hanging member 4, and the top of the spin-drying basket 3 needs to have a connecting structure, which limits the size of the opening at the top of the spin-drying basket 3. See also Figure 7 The upper basket 31 has a first opening 312, which occupies only about half the size of the cross-section of the upper basket 31. After the upper basket 31 is removed, the lower basket 32 ​​can have a larger opening, making it easier to put in and take out clothes.

[0037] Optionally, see Figure 7The bottom of the upper basket 31 is provided with a first annular convex edge 313, and the top of the lower basket 32 ​​is provided with a second annular convex edge 322. The first annular convex edge 313 and the second annular convex edge 322 correspond to each other. Several L-shaped hooks 314 are provided below the first annular convex edge 313. The L-shaped hooks 314 include a vertical bar portion 3142 and a horizontal bar portion 3141. The portion of the first annular convex edge 313 corresponding to the horizontal bar portion 3141 is provided with a first notch 315. The second annular convex edge 313... The upper half of the basket 32 ​​is provided with several hook holes 323, the number of which matches the number of L-shaped hooks 314. The L-shaped hooks 314 extend into the hook holes 323 and, after rotating, hook onto the lower surface of the second annular protrusion 322. The rotational hooking direction of the L-shaped hooks 314 is opposite to the rotation direction of the impeller 2 during dehydration. That is, viewed from above, if the impeller 2 rotates counterclockwise, the L-shaped hooks 314 rotate clockwise with the upper half of the basket 31 and hook onto the lower half of the basket 32. This is to prevent the L-shaped hooks 314 from detaching from the hook holes 323 when the impeller 2 drives the lower half of the basket 32 ​​to rotate, thus preventing the lower half of the basket 32 ​​from separating from the upper half of the basket 31.

[0038] This structure offers two advantages: first, it allows for a larger opening in the lower basket 32; second, it facilitates the assembly and disassembly of the upper basket 31 and the lower basket 32. Simply rotate the upper basket 31 and lift it to separate it from the lower basket 32. Alternatively, insert the L-shaped hook 314 of the upper basket 31 into the hook hole 323, and then rotate the upper basket 31 to connect it to the lower basket 32. During connection, the lower surface of the first annular protrusion 313 overlaps the upper surface of the second annular protrusion 322.

[0039] Optionally, see Figure 6 The suspension component 4 is provided with a shaft hole 51 and a supporting surface. A rotating shaft 6 is fixedly installed on the dehydration basket 3. The rotating shaft 6 is provided with an overlapping surface. The rotating shaft 6 is rotatably connected to the shaft hole 51, and the overlapping surface overlaps with the supporting surface, so that the dehydration basket 3 is rotatably hung on the suspension component 4. For details, see Figure 6 and Figure 7 A first blind hole 311 with an upward opening can be provided above the dehydration basket 3. One end of the rotating shaft 6 is fixedly installed in the first blind hole 311. The dehydration basket 3 can be made of plastic, and the rotating shaft 6 can be made of metal. The first blind hole 311 can be heat-fused and bonded to the rotating shaft 6 to form a fixed connection.

[0040] Thus, the suspension component 4 provides upward support to the dehydration basket 3 by supporting the overlapping surface on the rotating shaft 6 through the supporting surface. The dehydration basket 3 can rotate relative to the suspension component 4 around the axis of the rotating shaft 6 through the rotational cooperation of the rotating shaft 6 and the shaft hole 51.

[0041] Optionally, see Figure 4 and Figure 6The side wall of the rotating shaft 6 is provided with a second annular groove 61, and a retaining spring 7 is provided in the second annular groove 61. The side wall of the shaft hole 51 is provided with a first annular groove 52, and the retaining spring 7 is provided in the first annular groove 52. That is, the retaining spring 7 is simultaneously engaged in the first annular groove 52 and the second annular groove 61. The lower surface of the retaining spring 7 forms an overlapping surface, and the lower surface of the first annular groove 52 forms a supporting surface.

[0042] Optionally, see Figure 6 The suspension component 4 has a second blind hole 41 with an opening facing downward in the middle. A first cap 5 is interference-connected in the second blind hole 41. The first cap 5 has a shaft hole 51 and a support surface inside. A first annular groove 52 is provided on the side wall of the shaft hole 51, and the lower surface of the first annular groove 52 forms a support surface.

[0043] Optionally, see Figure 1 A suction cup 8 is provided at the bottom of the housing 1, specifically at the bottom of the bottom housing 12. The suction cup 8 can be a suction cup in the prior art.

[0044] The suction cup 8 can make the connection between the housing 1 and the ground more secure, which can further reduce the shaking of the dehydrator.

[0045] The above embodiments are merely illustrative of the present invention and not limiting. Under the concept of the present invention, the technical solutions without substantial changes are still within the protection scope of the present invention.
