Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a handle mounting structure and a dehumidifier. Background Technology

[0002] Household appliances such as dehumidifiers are usually equipped with handles for easy carrying and movement. Existing dehumidifier handle installation structures are mainly divided into two types: fixed and rotating. For rotating handles, both ends are connected to the body via pivots, allowing the handle to be switched between the usage position and the storage position.

[0003] Currently, most common rotating handle mounting structures use traditional damping shafts or simple interlocking snap-fit ​​connections for positioning. However, existing mounting structures have the following shortcomings in practical use: First, traditional damping structures often fail to provide a clear sense of gear position. When users rotate the handle, it is difficult to accurately stop it in the preset position such as vertical or horizontal in one go. They usually need to make repeated fine adjustments, resulting in a poor operating experience.

[0004] Secondly, when the handle is rotated to a horizontal position, due to the weight and lever arm of the handle itself, the traditional positioning structure is unable to resist the gravitational torque generated by the handle, causing the handle to deflect slightly downward when in a horizontal position. This makes it impossible for the handle to maintain a strictly horizontal posture, affecting the product's aesthetics and perceived quality.

[0005] In addition, existing left and right side mounting components usually require differentiation between left and right parts, resulting in higher mold costs and easy confusion or misassembly during assembly, affecting production efficiency. Summary of the Invention

[0006] To address the aforementioned issues, this application provides a handle mounting structure and a dehumidifier that enables precise hovering and position locking of the handle at a preset angle.

[0007] To achieve the above objectives, in a first aspect, embodiments of this application provide a handle mounting structure, including a housing, damping components fixed to the left and right side walls of the housing, a handle, and rotating components disposed at both ends of the handle; The damping element includes a ring-shaped frame and at least one elastic arm disposed inside the ring-shaped frame, and the elastic arm is provided with a positioning part. The rotating component has an axially extending first boss on one side, the first boss extends into the annular frame, and the outer peripheral surface of the first boss has a plurality of positioning grooves distributed along its circumference. When the rotating component rotates with the handle, the positioning part switches between different positioning slots. Under the elastic force of the elastic arm, the positioning part radially abuts against the positioning slot corresponding to the first boss, so that the handle can be maintained at the corresponding angular position.

[0008] Preferably, the handle can be switched between a drooping state, a horizontal state, and a vertical state, and when the handle is in the drooping state, it abuts against the side wall of one side of the housing.

[0009] Preferably, the positioning groove includes four first arc-shaped grooves and four second arc-shaped grooves, which are alternately arranged in sequence, and two elastic arms are provided; when the handle is in the horizontal state, two positioning parts cooperate with one pair of first arc-shaped grooves; when the handle is in the vertical state, two positioning parts cooperate with another pair of first arc-shaped grooves; when the handle is in the drooping state, two positioning parts cooperate with two of the second arc-shaped grooves.

[0010] Preferably, the two elastic arms are symmetrically arranged on the upper and lower sides of the annular frame, and the positioning part is a positioning post integrally formed with the elastic arm. The side of the positioning post facing the first boss has an arc-shaped positioning surface that matches the curvature of the first arc-shaped groove.

[0011] Preferably, the four first arc-shaped grooves include a first pair of first arc-shaped grooves and a second pair of first arc-shaped grooves. The first pair of first arc-shaped grooves are symmetrically arranged on the first boss. The angle between the center line of the second pair of first arc-shaped grooves and the center of the rotating member is less than 180 degrees. Each of the second pair of first arc-shaped grooves includes a first arc-shaped wall and a second arc-shaped wall connected to each other. The radial height of the first arc-shaped wall is greater than the radial height of the second arc-shaped wall. When the handle is in the horizontal state, the positioning part elastically abuts against the first arc-shaped wall.

[0012] Preferably, the other side of the rotating component is provided with an axially extending second boss, and the end of the handle is provided with a first mounting hole adapted to the second boss. The second boss is inserted into the first mounting hole. A pair of mutually cooperating positioning protrusions and positioning grooves are provided between the outer peripheral wall of the second boss and the hole wall of the first mounting hole. The positioning protrusions and the positioning grooves form an anti-rotation structure to prevent the rotating component from rotating relative to the handle. The anti-rotation structures at the left and right ends of the handle are arranged at an angle of 180 degrees in the circumferential direction.

[0013] Preferably, the rotating component located on the left side of the housing and the rotating component located on the right side of the housing have a 180-degree installation phase difference in the circumferential direction.

[0014] Preferably, the arc length of the second arc groove is greater than the arc length of the first arc groove, and the curvature of the second arc groove is less than the curvature of the first arc groove.

[0015] Preferably, the outer peripheral wall of the annular frame is provided with a plurality of elastic hooks; the housing is provided with an installation groove and a fixing shaft, the inner wall of the installation groove is provided with a snap-fit, and the damping element is fixed in the installation groove by the snap-fit ​​between the elastic hooks and the snap-fit; the first boss is provided with a second mounting hole adapted to the fixing shaft, and the fixing shaft is inserted into the second mounting hole and rotates with the first boss.

[0016] Secondly, embodiments of this application provide a dehumidifier, including the handle mounting structure described in any embodiment of the first aspect.

[0017] The handle mounting structure and dehumidifier designed in this application utilize the engagement of the annular frame of the damping component and the inner elastic arm with the first boss of the rotating component. The radial elastic force applied by the elastic arm allows the positioning part to precisely engage with the circumferentially distributed positioning grooves, achieving handle position switching and locking at a preset angle. This radially enveloping structure provides sufficient damping holding force within a limited space, effectively overcoming the gravitational torque of the handle and ensuring stable suspension of the handle in vertical, horizontal, or folded states, avoiding the defects of traditional structures that are prone to loosening and slippage.

Detailed Implementation

[0033] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0034] This application provides a dehumidifier 200, referring to... Figure 1 , Figure 2 The dehumidifier 200 includes a housing 201, a compressor, a heat exchanger, a fan, and a water tank, all housed within the housing 201. To facilitate user movement or transport of the dehumidifier 200, a rotatable handle is provided on the housing 201. Specifically, this application embodiment provides a handle mounting structure 100 for rotatably mounting a handle 20 to the housing 201.

[0035] Reference Figure 1 , Figure 2 Specifically, this application provides a handle mounting structure 100, which mainly includes damping components 10 fixed to the left and right side walls of the housing 201, a handle 20, and rotating components 30 disposed at both ends of the handle 20. The damping components 10 are fixed to the housing 201 and remain stationary, while the rotating components 30 are fixed to the handle 20 and rotate synchronously with the handle 20.

[0036] Reference Figure 7 , Figure 8 The damping element 10 can be a one-piece injection-molded plastic part, generally in the form of a circular or polygonal ring structure, including an outer ring frame 11 and a pair of elastic arms 12 disposed inside the ring frame 11. The pair of elastic arms 12 are centrally symmetrically distributed about the centerline of the ring frame 11, for example, located at... Figure 9 The upper left and lower right sides, or the upper and lower sides, within the annular frame 11 shown, are used to ensure that a balanced radial clamping force is applied to the rotating member 30.

[0037] In this embodiment, the elastic arm 12 can be a single cantilever beam structure, with one end integrally connected to the inner wall of the ring frame 11, and the other end suspended and capable of radial elastic deformation. A clearance groove 15 is provided between the elastic arm 12 and the inner peripheral wall of the ring frame 11 to allow the elastic arm 12 to undergo radial deformation. A positioning part 13 protruding inward toward the ring frame 11 is provided on the elastic arm 12.

[0038] In another embodiment, to balance the structural strength and flexibility of the elastic arm 12, see [reference needed]. Figure 7 , Figure 8 , Figure 9 The elastic arm 12 includes a first segment 121, a second segment 122, and a third segment 123. A positioning part 13 is located in the middle of the first segment 121. The first segment 121 can be a straight segment or an arc-shaped segment that curves towards the center of the annular frame 11, in which case the elastic arm 12 is approximately M-shaped. The second segment 122 is an arc-shaped segment that curves away from the center of the annular frame 11, and the second segment 122 is connected to the opposite ends of the first segment 121. One end of the third segment 123 is connected to the second segment 122, and the other end of the third segment 123 is connected to the inner wall of the annular frame 11.

[0039] In some embodiments, such as Figure 7 , Figure 8 As shown, to prevent the elastic arm 12 from breaking at its root during long-term repeated deformation, the first segment 121 is designed to be the thickest radially among the three segments, thus forming a reinforced stress-bearing zone. Figure 12 As shown, a reinforcing rib 16 is provided between the third segment 123 and the ring frame 11 to further enhance the structural strength of the connection between the elastic arm 12 and the ring frame 11, making it less prone to damage.

[0040] In some embodiments, the positioning part 13 may be configured as a positioning post integrally formed with the first segment 121 of the elastic arm 12, the positioning post being semi-cylindrical or arc-shaped and protruding towards the center. This arrangement places the positioning post at the position where the elastic arm has the best deformation capacity, ensuring both the holding force during locking and the smoothness during rotation switching.

[0041] Reference Figure 1 , Figure 9 , Figure 11 The rotating component 30 has an axially extending first boss 31 on one side. The annular frame 11 serves as an external fitting component, forming a circumferentially enclosing fit with the first boss 31, which serves as an internal fitting component. The outer circumferential surface of the first boss 31 has multiple positioning grooves 40 distributed along its circumference.

[0042] The core working principle of the handle mounting structure 100 is as follows: when the rotating component 30 rotates with the handle 20, the positioning part 13 on the damping component 10 will slide against the outer peripheral surface of the first boss 31 under the elastic action of the elastic arm 12. When the positioning part 13 rotates to align with a certain positioning groove 40, the positioning part 13 will move into the positioning groove 40 under the action of the elastic restoring force and radially abut against the groove wall or bottom of the positioning groove 40. Through this switching and cooperation between the positioning part 13 and different positioning grooves 40, the handle 20 can be maintained at the corresponding preset angle position, realizing a clear stopping function with a clear sense of stop.

[0043] In this embodiment, the handle 20 is designed to switch between a hanging state in the storage position and a horizontal and vertical state in the use position. When the handle 20 is in the hanging state, the main body of the handle 20 fits against the side wall of the housing 201, which is aesthetically pleasing and reduces the overall size of the machine, making it easier to package and transport.

[0044] In some embodiments, see Figure 9 , Figure 11 The positioning groove 40 includes four first arc-shaped grooves 41 and four second arc-shaped grooves 42. The first arc-shaped grooves 41 and the second arc-shaped grooves 42 are alternately arranged in the circumferential direction of the first boss 31. That is, the four first arc-shaped grooves are evenly arranged on the outer circumferential surface of the first boss 31 at a 90-degree interval, and the four second arc-shaped grooves 42 are evenly arranged on the outer circumferential surface of the first boss 31 at a 90-degree interval. Two elastic arms 12 are provided to cooperate with it and are symmetrically arranged on the upper and lower sides of the annular frame 11.

[0045] The specific cooperation relationship is as follows: See Figure 5 , Figure 9When the handle 20 is in a horizontal state, the positioning parts 13 on the two elastic arms 12 respectively engage in one of the pair of oppositely arranged first arc-shaped grooves 41 to provide horizontal positioning force. See Figure 3 , Figure 13 When the handle 20 is rotated to the vertical position, the two positioning parts 13 respectively engage in another pair of oppositely arranged first arc-shaped grooves 41 to provide vertical positioning force; See Figure 2 , Figure 14 When the handle 20 is rotated to the drooping state, the two positioning parts 13 respectively engage in the two opposite second arc-shaped grooves 42, and the positioning parts 13 abut against the end of one end of the second arc-shaped groove 42.

[0046] This design allows the handle to switch from one steady state to another during a 90-degree rotation, and the rotation is completed in one step without any additional adjustment.

[0047] Further, see Figure 8 , Figure 9 The positioning part 13, i.e. the positioning post facing the first protrusion 31, has an arc-shaped positioning surface 131. The curvature of the arc-shaped positioning surface 131 matches the curvature of the first arc-shaped groove 41, thereby increasing the contact area and making the positioning more stable.

[0048] See Figure 4 , Figure 9 To address the issue of handle sagging due to its own weight in a horizontal position, the four first arc-shaped grooves 41 in this embodiment are divided into a first pair and a second pair. The first pair of first arc-shaped grooves 41 corresponding to the handle 20 in a vertical position can be arranged symmetrically. Correspondingly, the angle α between the center of the second pair of first arc-shaped grooves 41 corresponding to the handle 20 in a horizontal position and the center of rotation of the rotating member 30 is designed to be slightly less than 180 degrees, for example, 176 to 179 degrees.

[0049] Alternatively, in terms of the shape of the groove walls, the second pair of first arc-shaped grooves 41 each includes a first arc-shaped wall 411 and a second arc-shaped wall 412 connected to each other. The direction in which the handle 20 rotates downward under gravity is defined as the downward rotation side, and the opposite is defined as the upward rotation side. The radial height of the first arc-shaped wall 411 located on the downward rotation side, that is, the degree of its vertical outward protrusion, is designed to be greater than the radial vertical height of the second arc-shaped wall 412 located on the upward rotation side.

[0050] See Figure 4 , Figure 9When the handle 20 is in a horizontal position, the positioning part 13 mainly elastically abuts against the higher first arc-shaped wall 411. Because the first arc-shaped wall 411 is higher, it forces the elastic arm 12 to produce greater deformation, thereby generating a greater reverse restoring force. This additional reverse torque can counteract the gravitational torque of the handle itself, so that the handle remains visually horizontal.

[0051] Furthermore, to differentiate the different tactile sensations, the arc length of the second arc groove 42 can be set to be greater than the arc length of the first arc groove 41, and the curvature of the second arc groove 42 is less than the curvature of the first arc groove 41. This means that when the handle 20 is in the folded position (drooping state), the tactile feedback when the handle 20 is turned out of the folded position is different from that when switching between horizontal and vertical positions, and the tactile feedback is more obvious and better.

[0052] In some embodiments, see Figure 5 , Figure 10 On the other side of the rotating component 30, i.e., the side opposite to the first boss 31, there is an axially extending second boss 32. The end of the handle 20 has a first mounting hole 21 adapted to the second boss 32. The second boss 32 is inserted into the first mounting hole 21, and a pair of cooperating positioning protrusions 33 and positioning grooves 22 are provided between the outer peripheral wall of the second boss 32 and the hole wall of the first mounting hole 21. The positioning protrusions 33 and positioning grooves 22 form an anti-rotation structure to prevent relative rotation between the rotating component 30 and the handle 20. Specifically, to achieve foolproof installation of the universal component on both sides, the anti-rotation structures in the first mounting holes 21 at the left and right ends of the handle 20 are arranged at angles differing by 180 degrees in the circumferential direction. For example, the positioning groove of the left mounting hole is located at the top, and the positioning groove of the right mounting hole is located at the bottom.

[0053] Correspondingly, the rotating component 30 located on the left side of the housing 201 and the rotating component 30 located on the right side of the housing 201 also have a 180-degree installation phase difference in the circumferential direction. Since the rotating components 30 on the left and right sides are universal components with identical structures, they only need to be rotated 180 degrees for installation. The position of the positioning protrusion 33 on it will change from the top to the bottom, thus perfectly matching the different mounting holes on the left and right ends of the handle, effectively preventing incorrect installation.

[0054] In some embodiments, to improve the overall appearance and aesthetics of the handle, the internal mechanical connection structure is concealed and dust is prevented from entering. See [reference needed]. Figure 1 , Figure 5 On the outer sides of the left and right ends of the handle 20, i.e. the side away from the housing 201, there are also shielding plates 50. The shielding plates 50 are covered on the outer opening of the first mounting hole 21 to cover the second boss 32 and the hole area of ​​the first mounting hole 21.

[0055] In some embodiments, a recessed platform or annular mounting groove is provided on the outer wall of the handle 20 around the first mounting hole 21. The depth of the recessed platform is adapted to the thickness of the shield 50. The shield 50 can be a circular thin sheet structure and can be fixed in the recessed platform by means of snap-fit ​​connection, adhesive backing, or interference fit. After installation, the outer surface of the shield 50 is flush with or forms a smooth transition with the outer surface of the handle 20, thereby visually forming a complete, closed and beautiful handle end shape.

[0056] In some embodiments, see Figure 6 , Figure 7 , Figure 8 The outer peripheral wall of the annular frame 11 is provided with multiple elastic hooks 14. Correspondingly, the side wall of the housing 201 is provided with a corresponding mounting groove 2011, and the inner wall of the mounting groove 2011 is provided with a locking slot 2012. During installation, the damping element 10 is pressed into the mounting groove 2011, and the elastic hooks 14 and the locking slots 2012 are engaged to achieve fixation.

[0057] See Figure 1 , Figure 6 The mounting groove 2011 has a fixed shaft 2013 at its center, and the first boss 31 has a second mounting hole 311 at its center that is adapted to the fixed shaft 2013. The fixed shaft 2013 is inserted into the second mounting hole 311, which serves to provide rotational support and positioning, ensuring smooth rotation.

[0058] In some embodiments, see Figure 6 , Figure 12 The outer peripheral wall of the ring frame 11 is also provided with a flat part. The mounting groove 2011 is provided with a limiting protrusion 2014 corresponding to the position of the flat part on the ring frame 11. When the ring frame 11 is installed in the mounting groove 2011, the stability of the ring frame 11 can be increased by the cooperation between the limiting protrusion 2014 and the flat part.

[0059] The handle mounting structure and dehumidifier provided in this application embodiment utilize the cooperation between the annular skeleton of the damping component and the inner elastic arm with the first boss of the rotating component. The radial elastic force applied by the elastic arm allows the positioning part to precisely engage with the circumferentially distributed positioning grooves, achieving handle position switching and locking at a preset angle. This radially enveloping structure provides sufficient damping holding force within a limited space, effectively overcoming the gravitational torque of the handle and ensuring stable suspension of the handle in vertical, horizontal, or folded states, avoiding the defects of traditional structures that are prone to loosening and slippage.
