[0002] Clothes processing equipment, such as heat pump washer-dryers, is a multifunctional household appliance that combines washing and drying functions. Typically, during the dehydration cycle, the drum of a heat pump washer-dryer transmits vibrations to the heat pump system through the support structure connected to the drum. The magnitude of this vibration directly affects the heat pump system's service life.

DETAILED DESCRIPTION

[0051] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the scheme of the embodiments of the present application will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present application, but the embodiments of the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, not all of the embodiments.

[0053] Existing support pads for heat pump systems are typically rubber pads, which have low inherent rigidity and can provide a certain degree of vibration reduction and isolation, making the heat pump system less susceptible to resonance damage. However, the rubber pads themselves have low structural strength, resulting in poor load-bearing capacity.

[0054] For this purpose, refer to Figures 1 to 5 As shown, this embodiment provides a footing support structure 100 , which includes a positive stiffness element 110 and a negative stiffness element 120 .

[0055] Specifically, the positive stiffness element 110 is used to connect to the heat pump system 300 , and the negative stiffness element 120 is connected to one side of the positive stiffness element 110 .

[0056] The positive stiffness element 110 is used to deform under the action of external force to provide positive stiffness, and the negative stiffness element 120 is used to deform in a direction opposite to the deformation direction of the positive stiffness element 110 under the action of external force to generate negative stiffness for balancing the positive stiffness. A weight reduction structure 200 is provided on the negative stiffness element 120 and at least one of the positive stiffness element 110 and the negative stiffness element 120 is a metal part or an alloy part.

[0057] Figure 1 and Figure 2 Illustrated is a positive stiffness element 110, Figures 3 to 5 The negative stiffness element 120 is shown. The positive stiffness element 110 is used to connect to the heat pump system 300 . Specifically, the negative stiffness element 120 can be connected to the side of the positive stiffness element 110 away from the heat pump system 300 . When in use, the positive stiffness element 110 mainly plays the role of bearing the weight of the heat pump system 300 and providing positive stiffness, and the negative stiffness element 120 mainly plays the role of providing negative stiffness to balance the positive stiffness. The deformation direction of the positive stiffness element 110 under the action of external force is opposite to the deformation direction of the negative stiffness element 120 under the action of external force. At this time, the entire base support structure 100 is almost not deformed in appearance, so that the base support structure 100 presents a quasi-zero stiffness state, that is, the base support structure 100 exhibits a stiffness characteristic close to zero near a certain specific equilibrium point. In this case, the deformation of the base support structure 100 is very small and can be approximated to zero. That is, when an external force acts on the base support structure 100, the interaction force between the molecules or atoms inside the entire structure is very large, so that the deformation is very small, thereby having excellent vibration isolation performance.

[0058] For example, refer to Figure 11 In the up and down directions shown, the positive stiffness element 110 can be deformed downward under the action of an external force, while the negative stiffness element 120 can be deformed upward under the action of an external force, that is, the deformation directions of the positive stiffness element 110 and the negative stiffness element 120 are opposite. At this time, the overall structure after the positive stiffness element 110 and the negative stiffness element 120 are assembled together basically does not deform in appearance, thereby achieving a quasi-zero stiffness characteristic.

[0059] Since the footing support structure 100 has a quasi-zero stiffness characteristic, the natural frequency of the heat pump system 300 is low and resonance is not likely to occur, thereby ensuring a long service life of the heat pump system 300. In other words, the footing support structure 100 of this embodiment plays an effective role in vibration isolation.

[0060] Specifically, refer to Figures 16 to 18 As shown, from Figure 16 and Figure 17 It can be seen that after adopting the foot support structure 100 of this embodiment, the vertical natural frequency of the heat pump system 300 drops from 28.1Hz to 15.6Hz, and the circumferential natural frequency drops from 15.7Hz to 12.4Hz. The vertical natural frequency curve of the heat pump system using the foot support structure of this embodiment can be referred to. Figure 16 As shown in S1 in FIG, the vertical natural frequency curve of the heat pump system in the prior art can be referred to Figure 16 The circumferential natural frequency curve of the heat pump system using the foot support structure of this embodiment can be referred to Figure 17 As shown in S3 in FIG, the circumferential natural frequency curve of the heat pump system in the prior art can be referred to Figure 17 In addition, the foot support structure 100 of this embodiment is under a load of 48N and within a displacement range of 2.4mm (refer to Figure 18 Within the interval indicated by the dotted rectangular box), the stiffness of the entire structure is 0N / mm, so it can have good vibration isolation performance and can effectively reduce the natural frequency of the entire heat pump system 300. The displacement stiffness curve of the foot support structure 100 of this embodiment is shown in FIG. Figure 18 As shown in S5 in FIG, the displacement stiffness curve of the foot support structure 100 in the prior art is referred to Figure 18 As shown in S6 in.

[0061] It should be noted that the external forces acting on the positive stiffness element 110 and the negative stiffness element 120 mainly come from the gravity of the compressor 310 and the vibration force of the compressor 310 .

[0062] For example, the positive stiffness element 110 and the negative stiffness element 120 can be connected by a snap-fit ​​or sleeve-fit method. The positive stiffness element 110 and the heat pump system 300 can be connected by a snap-fit, sleeve-fit, or screw-fit method. Specifically, the positive stiffness element 110 can be connected to the compressor 310 of the heat pump system 300.

[0063] Furthermore, the positive stiffness element 110 and the negative stiffness element 120 deform under the action of an external force, thereby forming positive stiffness and negative stiffness, respectively. Positive stiffness herein refers to deformation that increases with increasing external force, while negative stiffness refers to deformation that decreases with increasing external force. For example, the positive stiffness element 110 may be a rubber pad, a positive stiffness spring, or the like, while the negative stiffness element 120 may be a disc spring, a diaphragm spring, or the like.

[0064] At the same time, at least one of the positive stiffness element 110 and the negative stiffness element 120 is a metal part or an alloy part. The metal part or the alloy part itself has a relatively high structural strength, and therefore has a relatively high load-bearing capacity.

[0065] For example, both the positive stiffness element 110 and the negative stiffness element 120 can be metal or alloy components, or only one of the positive stiffness element 110 and the negative stiffness element 120 can be metal or alloy components. In this embodiment, to balance the load-bearing capacity, weight, and cost of the footing support structure 100, only the negative stiffness element 120 can be metal or alloy components. Specifically, the negative stiffness element 120 can be made of stainless steel or galvanized sheet metal.

[0066] In addition, a weight reduction structure 200 may be provided on the negative stiffness element 120 to reduce the weight of the negative stiffness element 120 , thereby achieving a lightweight design of the entire footing support structure 100 .

[0067] As can be seen from the above, the footing support structure 100 of this embodiment not only achieves a quasi-zero stiffness characteristic to provide a vibration isolation effect, thereby preventing the heat pump system 300 from easily incurring resonance damage, but also has a strong load-bearing capacity. Specifically, the footing support structure 100 of this embodiment utilizes the principle of positive and negative stiffness offset to maintain a low system stiffness under a certain load without sacrificing load-bearing capacity, thereby providing a vibration isolation effect and preventing the heat pump system 300 from experiencing resonance damage that could affect its service life.

[0068] Reference Figures 3 to 5As shown, in some embodiments, the negative stiffness element 120 includes a connecting body 121 and a deformable body 122 connected to the side of the connecting body 121 away from the positive stiffness element 110. The connecting body 121 is connected to the positive stiffness element 110, and the weight reduction structure 200 is provided on the deformable body 122. Along the direction from the positive stiffness element 110 to the negative stiffness element 120, the deformable body 122 is a tapered structure with a gradually increasing inner diameter, and the ratio of the cone height to the wall thickness of the tapered structure is greater than Thus, the negative stiffness element 120 can be deformed under the action of external force and provide negative stiffness.

[0069] Specifically, the ratio of the cone height t to the wall thickness h of the cone structure can be greater than That is, the principle of forming negative stiffness of the negative stiffness element 120 of this embodiment is similar to the principle of achieving negative stiffness of existing disc springs.

[0070] When implementing it, refer to Figure 5 In the up and down directions shown, the deformable body 122 can be connected to the lower side of the connecting body 121. The deformable body 122 is in a compressed state in the initial state, and its own inner diameter gradually increases from top to bottom to form a conical structure. Therefore, the deformable body 122 can be deformed upward under the action of external force as the external force increases, thereby providing negative stiffness.

[0071] For example, the connecting body 121 and the connecting body 121 may be integrally formed to save manufacturing steps and enhance the structural strength of the entire negative stiffness element 120 .

[0072] Reference Figure 3 and Figure 4 As shown, in some embodiments, the deformable body 122 includes a plurality of deformable blades 123 arranged at circumferential intervals along the connecting body 121, and all the deformable blades 123 together form a conical structure that can provide negative stiffness, and the gaps between adjacent deformable blades 123 form a weight-reducing structure 200, that is, the weight-reducing structure 200 is essentially a weight-reducing notch or a weight-reducing groove.

[0073] Compared with the structure of the existing disc spring, the deformable leaves 123 in this embodiment have a gap between two adjacent deformable leaves 123, so the weight of the entire deformable body 122 can be effectively reduced, which is conducive to achieving a lightweight design.

[0074] For example, the deformed blade 123 may be configured as follows: Figure 4 The number of the deformed blades 123 shown is six, or may also be seven or eight. The specific number of the deformed blades 123 may be set according to actual needs.

[0075] Reference Figure 3 and Figure 4As shown, in some embodiments, the weight reduction structure 200 can be an arc-shaped structure extending along the circumference of the connecting body 121, making its appearance more beautiful. In addition, the cross-sectional dimensions of all deformed blades 123 are consistent or different, so that they can be set according to actual structural design requirements.

[0076] For example, the cross-sectional dimensions of at least two of all the deformed blades 123 in this embodiment may be set to be different, for example, referring to Figure 4 Among the six deformed blades 123 shown, some have larger cross-sectional dimensions and some have smaller cross-sectional dimensions. This arrangement can balance the lightweight design requirements of the deformed body 122 and the structural strength design requirements of the deformed body 122.

[0077] Reference Figure 3 and Figure 4 As shown, in some embodiments, the size of the deformed blade 123 along the circumference of the connecting body 121 gradually increases from the inner edge to the outer edge of the deformed blade 123, thereby effectively increasing the structural strength of the deformed blade 123, so that the entire base support structure 100 has a higher structural strength.

[0078] In some embodiments, an annular connector 124 is provided on one side of the deformed blade 123 away from the connecting body 121 , so as to connect the outer edges of all the deformed blades 123 , thereby making the structure of the entire deformed body 122 more stable and having higher structural strength.

[0079] Reference Figure 3 and Figure 5 As shown, in some embodiments, the connecting body 121 includes a cylindrical body 125 and a sheet body 126 connected to the outer edge of the cylindrical body 125; the cylindrical body 125 is connected to the positive stiffness element 110, and the sheet body 126 is connected to the inner edge of the deformation body 122 and is supported on the side of the positive stiffness element 110 close to the negative stiffness element 120.

[0080] That is to say, by setting the connecting body 121 to include two parts, namely the cylindrical body 125 and the sheet body 126, a reliable connection with the positive stiffness element 110 can be achieved through the cylindrical body 125, and the positive stiffness element 110 can also be supported by the sheet body 126 to further improve the matching reliability between the two.

[0081] For example, the cylindrical body 125 and the sheet body 126 can be integrally formed to save manufacturing steps and improve the overall structural strength of the connecting body 121. Alternatively, the cylindrical body 125 and the sheet body 126 can be formed separately and then fixed together by snapping or welding.

[0082] Specifically, the connection structure between the cylindrical body 125 and the positive stiffness element 110 is as follows: a through hole 111 is provided on the positive stiffness element 110, and at least a portion of the cylindrical body 125 is sleeved in the through hole 111, thereby realizing a snap-on connection between the two to simplify the connection structure and connection operation.

[0083] In some embodiments, the sheet 126 and the positive stiffness element 110 are disposed in close contact with each other to increase the contact area therebetween, thereby further enhancing the supporting effect of the sheet 126 and the positive stiffness element 110 .

[0084] For example, the positive stiffness element 110 in this embodiment is a rubber pad, and specifically can be made of EPDM (Ethylene Propylene Diene Monomer) material, which has low stiffness and low material cost.

[0085] Reference Figure 1 and Figure 2 、 Figures 15 to 17 As shown, in some embodiments, at least two first flanges 112 are formed on the outer wall of the positive stiffness element 110, and the at least two first flanges 112 are spaced apart in the direction from the positive stiffness element 110 to the negative stiffness element 120, and a snap-fitting groove 113 that snaps into engagement with a snap-fitting portion on the compressor 310 of the heat pump system 300 is formed between any two adjacent first flanges 112, thereby achieving connection with the heat pump system 300.

[0086] In a specific implementation, the snap-fitting portion can be a connecting ear 311 provided on the outer wall of the compressor 310 of the heat pump system 300. The connecting ear 311 has a snap-fitting hole for passing the positive stiffness element 110. The connecting ear 311 is snap-fitted into the snap-fitting groove 113 to achieve a reliable connection between the positive stiffness element 110 and the compressor 310 of the heat pump system 300.

[0087] For example, in order to facilitate the connecting ear 311 to be installed downward from the top of the positive stiffness element 110 and to be clamped in the clamping groove 113, a clamping groove 113 can be formed between the uppermost first flange 112 and the first flange 112 adjacent to the uppermost first flange 112, and the outer diameter of the uppermost first flange 112 is smaller than the lower first flange 112 adjacent to it, so as to facilitate the connection ear 311 to be clamped in the clamping groove 113 after the perforation of the connecting ear 311 passes through the first flange 112.

[0088] Exemplarily, the number of the first flanges 112 may be only two, or in order to enhance the structural strength of the positive stiffness element 110 , the number of the first flanges 112 may be three or more, thereby increasing the strength of the positive stiffness element 110 by increasing the number of the first flanges 112 .

[0089] In addition, in order to facilitate the connecting ear 311 to pass through the through-hole of the positive stiffness element 110 and be clamped in the clamping groove 113, a guide surface 114 can be formed on the outer wall of the uppermost first flange 112. The guide surface 114 can be a guiding slope, and along the penetration direction of the connecting ear 311, the guiding slope is inclined toward the center of the through-hole.

[0090] Reference Figure 1 and Figure 2 As shown, in some embodiments, the snap-fit ​​groove 113 is an annular groove extending along the circumference of the positive stiffness element 110. At this time, after the connecting ear 311 on the compressor 310 is snap-fitted into the annular groove, the connecting ear 311 and the positive stiffness element 110 are snap-fitted in contact along the circumference of the entire positive stiffness element 110, thereby achieving a reliable connection between the two and preventing axial disengagement.

[0091] Reference Figures 8 to 12 As shown, in some embodiments, the base support structure 100 further includes a support 130, which is located on a side of the negative stiffness element 120 away from the positive stiffness element 110, and the support 130 has a cavity 131 opening toward the negative stiffness element 120, and the negative stiffness element 120 is snapped into the cavity 131.

[0092] In specific implementation, after the negative stiffness element 120 is connected to the positive stiffness element 110 , the negative stiffness element 120 is clamped in the cavity 131 of the support 130 , thereby carrying or supporting the entire positive stiffness element 110 and the negative stiffness element 120 .

[0093] Specifically, the outer diameter of the negative stiffness element 120 is exactly matched with the inner diameter of the cavity 131 , so that the negative stiffness element 120 can be exactly engaged in the cavity 131 and will not be easily separated.

[0094] For example, the support 130 can be made of metal or alloy to provide good load-bearing capacity. Furthermore, the support 130 can be used to indirectly connect to the drum of the laundry processing device. In this case, the vibration generated by the drum during dehydration can be transmitted to the heat pump system 300 through the support 130, the negative stiffness element 120, and the positive stiffness element 110 in sequence.

[0095] Reference Figure 8 As shown, in some embodiments, a step structure 132 is formed in the cavity 131, and a side of the step structure 132 facing the negative stiffness element 120 forms a first support surface 133. Part of the negative stiffness element 120 is placed on the first support surface 133 to support the negative stiffness element 120 through the first support surface 133, thereby improving the matching reliability between the two.

[0096] Illustratively, the first supporting surface 133 may be a plane perpendicular to the deformation direction of the negative stiffness element 120 , so as to effectively increase the contact area between the first supporting surface 133 and the negative stiffness element 120 , thereby effectively improving the supporting effect.

[0097] Reference Figure 8 and Figure 9 As shown, in some embodiments, the support 130 includes a first support tube 134 and a second support tube 135 connected to one side of the first support tube 134, the inner diameter of the first support tube 134 is larger than the inner diameter of the second support tube 135, and a step structure 132 is formed at the connection between the first support tube 134 and the second support tube 135.

[0098] That is to say, compared with the method of additionally connecting the step structure 132 in one support tube, the step structure 132 is formed by providing two support tubes with different inner diameters, which is simpler to manufacture and has lower cost.

[0099] For example, the first support tube 134 and the second support tube 135 can be integrally formed to save manufacturing steps and improve the structural strength of the entire support 130. Alternatively, the first support tube 134 and the second support tube 135 can also be formed separately and then welded or clamped together.

[0100] Reference Figure 6 and Figure 7 As shown, in some embodiments, the base support structure 100 further includes an elastic buffer 140, which is located in the cavity 131 and on the side of the negative stiffness element 120 away from the positive stiffness element 110. The side of the elastic buffer 140 facing the negative stiffness element 120 forms a second support surface 141 supporting the negative stiffness element 120, so that the elastic buffer 140 can support the negative stiffness element 120 and play a buffering role, thereby preventing the negative stiffness element 120 from deforming under the action of external force and squeezing the support 130 to form abnormal deformation and cause failure.

[0101] Exemplarily, the elastic buffer 140 may be a rubber pad or a silicone pad.

[0102] Reference Figures 6 to 8 As shown, in some embodiments, a sleeve portion 136 is provided in the support 130, and a connecting portion is provided in the elastic buffer 140. The elastic buffer 140 is connected to the support 130 through the cooperation of the connecting portion and the sleeve portion 136, thereby preventing the elastic buffer 140 from being detached from the support 130.

[0103] Specifically, one of the sleeve portion 136 and the connecting portion is a clamping column, and the other is a clamping hole 142 that is clamped with the clamping column. By inserting the clamping column into the clamping hole 142, a reliable connection between the elastic buffer 140 and the support 130 is achieved.

[0104] For example, a clamping column can be formed in the support 130 and a clamping hole 142 can be provided on the elastic buffer 140. Alternatively, a clamping hole 142 can be formed in the support 130 and a clamping column can be provided on the elastic buffer 140.

[0105] Reference Figures 6 to 8 As shown, the outer edge of the elastic buffer 140 is provided with a second flange 143, and the outer wall of the sleeve portion 136 and the inner wall of the support 130 are jointly enclosed to form a receiving groove 150 adapted to the second flange 143. By accommodating the second flange 143 in the receiving groove 150, it can play a positioning role and also play a fixing role for the elastic buffer 140.

[0106] Reference Figures 1 to 18 As shown, this embodiment further provides a clothes processing device, including a heat pump system 300 and the above-mentioned base support structure 100 . The heat pump system 300 includes a compressor 310 , and the base support structure 100 is installed below the body of the compressor 310 .

[0107] The specific structure and implementation principle of the base support structure 100 in this embodiment are the same as those of the above-mentioned base support structure 100 and can bring the same or similar technical effects. They will not be described in detail here, and the details can be referred to the above description.

[0108] Illustratively, the clothes processing device may be, for example, a dryer with a drying function or a washer-dryer.
