Referring to fig. 1 to 4, an embodiment of the present utility model provides a drain pump vibration damping device, which includes a base 11, a drain pump 12, a vibration damping pad 13, and a connecting member 14.

An embodiment of the present utility model provides a laundry treating apparatus 1 including a cabinet 10, a drum assembly, and a drain pump vibration damping device of any embodiment of the present utility model.

The box 10 is arranged above the base 11, and the cylinder assembly is arranged in the box 10.

The box 10 provides accommodation space and protection for the barrel assembly, and the box 10 keeps apart barrel assembly and external world, prevents that barrel assembly from exposing outside, reduces the probability that impurity such as external dust and barrel assembly contacted, when laundry treatment device 1 received the impact, box 10 also can effectively keep out external impact, avoids barrel assembly to receive the harm.

The base 11 provides support for the cabinet 10, and the bottom side of the base 11 may be provided with feet that bear the weight of the laundry treatment apparatus 1 and its load, through which the laundry treatment apparatus 1 is supported on the ground, and which prevent water, dust, etc. from penetrating into the inside of the components of the cabinet 10, etc.

The material and the molding mode of the base 11 are not limited, and for example, the base 11 may be an integral injection molding member, and the strength is high and the number of parts is small.

The cartridge assembly is for providing space for the laundry and the handling of the laundry, and illustratively in some embodiments the cartridge assembly includes an inner cartridge and an outer cartridge, the outer cartridge being sleeved outside the inner cartridge, the outer cartridge being for containing water for washing the laundry, the inner cartridge being for containing the laundry, in which embodiment the inner cartridge is for containing water through the outer cartridge, the inner cartridge also being referred to as a perforated inner cartridge. In other embodiments, the inner cylinder can hold water by itself and can also be called a non-porous inner cylinder, and the outer part of the inner cylinder can be provided with or without an outer cylinder.

The base 11 has a mounting cavity 11a, a top end of the mounting cavity 11a has an opening 11b, and a bottom end is formed with a stopper structure 11c.

The drain pump 12 is used for draining water inside the drum assembly to the outside, specifically, the drain pump 12 has a drain port, the laundry treating apparatus 1 includes a drain pipe 15, a water inlet end of the drain pipe 15 is connected to the drain port, and when the laundry treating apparatus 1 needs to drain water, the drain pump 12 pumps out water inside the drum assembly and pumps out water through a water outlet end of the drain pipe 15 to the outside.

The drain pump 12 has a support leg 121, and at least part of the structure of the vibration damping pad 13 is disposed between the bottom wall of the support leg 121 and the top wall of the base 11, and the vibration damping pad 13 has a through hole 13a communicating with the installation cavity 11 a.

The vibration damping pad 13 is a material having a vibration damping effect.

The connecting piece 14 is arranged in the through hole 13a and the installation cavity 11a in a penetrating way and is used for installing the drainage pump 12 on the base 11, and the stop structure 11c is used for abutting against the part of the connecting piece 14 extending into the installation cavity 11 a.

In the drain pump vibration damping device provided by the embodiment of the utility model, the vibration damping pad 13 isolates the supporting leg 121 of the drain pump 12 from the base 11, that is, the supporting leg 121 is not in direct contact with the base 11, the vibration damping pad 13 is positioned on the acting force transmission path of the supporting leg 121 and the base 11, specifically, at least part of gravity and vibration of the drain pump 12 are transmitted to the vibration damping pad 13, and the vibration damping pad 13 transmits the received gravity and vibration to the base 11; a part of the vibration generated by the drain pump 12 is absorbed by the vibration damping pad 13, and the vibration and noise transmitted to the base 11 can be reduced.

The vibration absorbing pad 13 absorbs vibration by utilizing its own performance, the vibration absorbing pad 13 can deform under the action of external force, and the polymer chains of the materials generate friction effect to each other, so that vibration energy is emitted in the form of heat energy. The vibration damping effect of the vibration damping pad 13 is affected by the amount of deformation thereof. In the embodiment of the utility model, the connecting piece 14 is penetrated in the through hole 13a and the mounting cavity 11a, and the vibration damping pad 13 is deformed under the action of the acting force from the connecting piece 14. If the vibration-damping pad 13 is pressed to hardly generate deformation or the deformation is excessively large, the vibration-damping effect of the vibration-damping pad 13 is affected, specifically, if the vibration-damping pad 13 is subjected to small force of the connecting member 14 to hardly generate pre-deformation, at this time, the connecting member 14 cannot tightly connect the supporting leg 121, the vibration-damping pad 13 and the base 11 together, when the drain pump 12 is operated, the connecting member 14 may be loosened or even separated due to severe vibration generated by the drain pump 12, and the vibration-damping pad 13 cannot effectively absorb vibration generated by the drain pump 12, so that the normal operation of the laundry treatment apparatus 1 is affected; when the force applied to the vibration-damping pad 13 is too large, the compression deformation of the vibration-damping pad 13 is too large, the characteristics of the vibration-damping pad are affected, the absorption of the vibration-damping pad 13 to the vibration is greatly reduced, and even the vibration-damping pad 13 is cracked due to the too large deformation.

Therefore, in order to ensure a good vibration damping effect of the vibration damping pad 13, the amount of compressive deformation of the vibration damping pad 13 needs to be controlled within a proper range at the time of assembly. Therefore, in the drainage pump vibration damper according to the embodiment of the present utility model, when the first end of the connecting piece 14 passes through the through hole 13a and is inserted into the mounting cavity 11a during assembly, when a part of the structure of the connecting piece 14 abuts against the stop structure 11c, the connecting piece 14 cannot be further inserted into the mounting cavity 11a, so that the depth of the connecting piece 14 inserted into the mounting cavity 11a can be limited, the probability of excessively pressing the vibration damping pad 13 by the connecting piece 14 can be reduced, and the probability of excessively deforming the vibration damping pad 13 due to being pressed can be reduced, thereby ensuring the vibration damping effect of the vibration damping pad 13, and increasing the vibration damping reliability of the vibration damping pad 13.

In some embodiments, referring to fig. 1 to 4, the connecting member 14 is not in contact with the supporting leg 121, i.e. any portion of the connecting member 14 is not in direct contact with the supporting leg 121. Vibration generated by the drainage pump 12 during operation cannot be directly transmitted to the connecting piece 14 through the supporting leg 121 and then transmitted to the base 11 through the connecting piece 14, and when the drainage pump 12 operates, the vibration generated by the drainage pump 12 can only be transmitted to the base 11 through the vibration damping pad 13, that is, the vibration generated by the drainage pump 12 can only be absorbed by the vibration damping pad 13 first and then transmitted to the base 11, so that the vibration transmitted to the base 11 is effectively reduced, and the vibration damping effect of the vibration damping pad 13 is increased.

The specific configuration of the vibration damping pad 13 is not limited.

In some embodiments, referring to fig. 3 and 4, the supporting leg 121 has a connecting hole 121a extending along the height direction of the base 11, the damping pad 13 includes a barrel 131 and a first flange 132 disposed at the bottom end of the barrel 131, the barrel 131 is disposed through the connecting hole 121a, the space in the barrel 131 defines the through hole 13a, and the first flange 132 is sandwiched between the top wall of the base 11 and the bottom wall of the supporting leg 121.

The first flange 132 can increase the contact area between the vibration damping pad 13 and the base 11, and can also reliably support the support leg 121, preventing the support leg 121 from contacting the base 11.

The specific shape and number of the support legs 121 are not limited.

The tube 131 is arranged in the connecting hole 121a in a penetrating way, the connecting hole 121a restrains the tube 131, the vibration damping pad 13 can be positioned, the probability of moving dislocation of the vibration damping pad 13 during assembly is reduced, the assembly reliability is improved, and the whole structure of the drainage pump vibration damping device is more compact.

In some embodiments, referring to fig. 3 and 4, the vibration-damping pad 13 further includes a second flange 133 disposed at the top end of the barrel 131, and the supporting leg 121 is disposed between the first flange 132 and the second flange 133. The support leg 121 is disposed between the first flange 132 and the second flange 133, which reduces the likelihood that the support leg 121 will contact the base 11 and the connecting member 14, and reduces the likelihood that the connecting member 14 will transmit vibrations to the base 11.

The supporting leg 121 is disposed between the first flange 132 and the second flange 133, and it is understood that the top wall of the supporting leg 121 abuts against the second flange 133, and that a gap is formed between the top wall of the supporting leg 121 and the second flange 133.

When the top wall of the supporting leg 121 abuts against the second flange 133, the supporting leg 121 contacts with the vibration-damping pad 13 more tightly, so as to enhance the connection stability, so that the overall structure of the drainage pump vibration-damping device is more compact, and the vibration-damping pad 13 is convenient to absorb the vibration from the supporting leg 121.

When a gap exists between the top wall of the supporting leg 121 and the second flange 133, the connecting piece 14 connects the vibration-damping pad 13 and the base 11, so that the supporting leg 121 is not pressed, the probability of deformation of the supporting leg 121 due to the acting force of the connecting piece 14 is reduced, and the service life of the drain pump 12 is prolonged.

The material of the vibration damping pad 13 is not limited as long as it has a good vibration damping and noise reducing effect, and it is, for example, rubber, silica gel, resin, fiber, or the like. In some embodiments, the vibration damping pad 13 is a rubber pad, has a good vibration damping effect, is convenient and simple to install, has a small volume and light weight, does not increase the overall weight of the laundry treatment apparatus 1, and is convenient to install and detach.

The forming mode of the vibration damping pad 13 is not limited, and the vibration damping pad 13 is an integrated forming structure, so that the production cost is low, the production speed is high, and the installation procedure can be reduced.

The manner in which the connecting member 14 is engaged with the vibration damping pad 13 is not limited.

In some embodiments, referring to fig. 1 and 2, one end of the connecting piece 14 presses against the second flange 133, and the other end abuts against the stop structure 11 c; when the connecting member 14 receives an external force, the second flange 133 may increase the contact area of the vibration-damping pad 13 and the connecting member 14, improve the stress condition of the vibration-damping pad 13, increase the service life of the vibration-damping pad 13, or,

in other embodiments, the damping device of the drain pump 12 includes a spacer, which covers the second flange 133, and one end of the connecting member 14 is pressed against the spacer, and the other end abuts against the stop structure 11c. At this time, the connecting piece 14 is not in direct contact with the vibration-damping pad 13, the connecting piece 14 is sequentially arranged in the gasket, the through hole 13a and the installation cavity 11a in a penetrating way, the gasket protects the vibration-damping pad 13 from direct acting force of the connecting piece 14, when the connecting piece 14 receives external acting force, the gasket receives acting force of the connecting piece 14, stress conditions of the vibration-damping pad 13 are improved, the acting force of the connecting piece 14 is dispersed to the top surface of the second flange 133 by the gasket, so that stress of the second flange 133 is uniform, the probability of deformation of the vibration-damping pad 13 due to larger acting force is reduced, and the service life of the vibration-damping pad 13 is prolonged.

In some embodiments, the through holes 13a, the connection holes 121a, and the mounting cavities 11a are coaxially disposed in pairs. Thus, the whole assembly of the drainage pump vibration damper is convenient, and the connection piece 14 is convenient to be matched with the vibration damper pad 13 and the base 11. The shape of the through hole 13a and the connection hole 121a is not limited, and may be circular, elliptical, or the like.

The structure of the connecting member 14 is not limited, and may be a bolt or a fastening screw.

In some embodiments, the connector 14 is a set screw. During assembly, the fastening screw passes through the through hole 13a and is directly connected with the inner wall of the mounting cavity 11a, the assembly is simple and convenient, in addition, the position of the stop structure 11c can be defined according to the type of the fastening screw to be used, and the stop effect is achieved, so that the fastening screw is prevented from being tightened to excessively compress the vibration reduction pad 13, and the vibration reduction work of the vibration reduction pad 13 is influenced. The inner wall of the mounting chamber 11a may be provided with or without an internal thread, and whether or not to prepare an internal thread may be selected according to the type of the fastening screw.

The kind of the fastening screw is not limited, and may be a pan head screw, a cylindrical head screw, a tapping screw, or the like.
