As shown in fig. 1, in some embodiments, a housing 100 of the drum washing machine is disposed on a horizontal plane, and one end of the housing 100 is provided with an opening for putting washed laundry into the drum washing machine.

As shown in fig. 1, in some embodiments, the washing tub 200 of the drum washing machine is disposed in the case 100, and the washing tub 200 further includes an inner tub and an outer tub, wherein the inner tub is rotatably connected with the outer tub, i.e., the inner tub and the outer tub can rotate with respect to each other.

The outer barrel is fixedly arranged in the shell 100, namely, the positions of the outer barrel and the shell 100 are relatively fixed, the outer barrel is a cylinder part, the outer barrel further comprises an outer barrel side wall, an opening of the outer barrel and an outer barrel bottom wall, the opening of the outer barrel and the outer barrel bottom wall are relatively arranged at two ends of the outer barrel side wall, and the opening of the outer barrel corresponds to the opening direction of the shell 100.

The inner barrel is rotatably arranged in the outer barrel, the inner barrel is a cylindrical part, the inner barrel further comprises an inner barrel side wall, an opening of the inner barrel and an inner barrel bottom wall, the opening of the inner barrel and the inner barrel bottom wall are oppositely arranged at two ends of the inner barrel side wall, and the opening of the inner barrel corresponds to the opening of the outer barrel and the opening direction of the shell 100.

It should be noted that, the first connector 700, the second connector 800, the third connector 900, the fourth connector 1000, the motor 300, the fixing cover 600, the elastic member 500 and the mounting base 400 described below are all disposed outside the washing tub 200, and therefore, the positional relationship with respect to the washing tub 200 refers to the positional relationship with respect to the outer tub of the washing tub 200, and the opening of the washing tub 200, the side wall of the washing tub 200 and the bottom wall of the washing tub 200 refer to the outer tub opening, the outer tub side wall and the outer tub bottom wall, respectively.

As shown in fig. 2 to 5, in some embodiments, a motor 300 is provided at one side of the washing tub 200 and is connected to the washing tub 200, and the motor 300 is used to rotate the washing tub 200.

The motor 300 is generally configured to transmit power output from the motor 300 to the inner tub of the washing tub 200 through a belt transmission or a gear transmission to rotate the inner tub of the washing tub 200 with respect to the outer tub of the washing tub 200.

It should be noted that, since the motor 300 is disposed in the limited space of the case 100 at one side of the tub 200 and also needs to transmit power to the inner tub of the tub 200 to rotate the inner tub of the tub 200, the motor 300 is generally fixedly disposed on the outer tub sidewall of the tub 200 in the related art due to the limitation of various factors.

When the motor 300 is started, the motor 300 converts the electric energy of the power supply into kinetic energy and transmits the kinetic energy to the inner tub of the washing tub 200, the motor 300 inevitably generates vibration during the operation, and the outer tub of the washing tub 200 fixedly connected with the motor 300 receives the vibration transmitted by the motor 300, generates a lot of noise and affects the operation of the inner tub of the washing tub 200.

As shown in fig. 7 to 15, in some embodiments, the mounting base 400 is a plate-shaped member, the mounting base 400 is disposed at an end of the tub 200 remote from the opening of the housing 100, the mounting base 400 is connected to the tub 200, and the mounting base 400 further includes a fixing portion 401 and a connecting portion 402.

The material of the mount 400 is a rigid material to provide the mount 400 with greater resistance to deformation when subjected to a force, and the materials used for the mount 400 include, but are not limited to: metal materials, composite materials and polymeric materials; when the motor 300 transmits vibration to the tub 200 through the mount 400, the mount 400 needs to have higher rigidity to prevent damage caused by deformation due to the vibration.

The mount 400 is used to connect with the first and second connection members 700 and 800 such that the first and second connection members 700 and 800 cannot directly contact with the tub 200, thereby reducing the vibration of the motor 300 directly transmitted to the tub 200 through the first and second connection members 700 and 800.

The mounting base 400 is used for being connected with the first and second connection members 700 and 800 to solve the problem that the first and second connection members 700 and 800 are difficult to be disposed on the smooth tub 200 wall.

The mount 400 is easier to mount the first and second connectors 700 and 800, so that the number of the junctions of the first and second connectors 700 and 800 and the mount 400 can be precisely determined.

The fewer the number of the joints between the mount 400 and the first and second connectors 700 and 800, the fewer the vibrations the motor 300 directly transmits to the mount 400 through the first and second connectors 700 and 800, and the two joints between the mount 400 and the first and second connectors 700 and 800 are provided in the drum washing machine according to the present application in consideration of the vibration reduction effect.

However, the fewer the number of the joints between the mount 400 and the first and second connection members 700 and 800, the more stress is required to be borne by the joints between the mount 400 and the first and second connection members 700 and 800, respectively, so that the joints between the mount 400 and the first and second connection members 700 and 800 should be reinforced in practical applications, and the fewer the number of the joints between the mount 400 and the first and second connection members 700 and 800 should not be set, the better the damage to the joints between the mount 400 and the first and second connection members 700 and 800 due to the vibration of the motor 300 should be considered in practical applications.

As shown in fig. 7 to 15, in some embodiments, a fixing portion 401 is provided at an end of the tub 200 remote from the opening of the case 100, the fixing portion 401 is coaxially disposed with the tub 200, the fixing portion 401 is disposed at an outer side of a bottom wall of the tub 200, and a through hole is formed in the fixing portion 401.

It should be noted that, the more the number of the connecting parts 402 and the connecting side walls of the fixing part 401 are used to connect the connecting side walls of the washing tub 200, the more stable the relative positions of the whole mounting base 400 and the connecting side walls of the washing tub 200 are, and the number of the connecting parts 402 and the connecting side walls should be set according to practical situations.

As shown in fig. 7 to 15, in some embodiments, the mount 400 extends in a direction away from the opening of the case 100 for increasing the thickness of the mount 400 in the axial direction of the tub 200, thereby moving the first and second connection members 700 and 800 away from the tub 200.

The mounting seat 400 extends in a direction away from the opening of the case 100 for increasing the thickness of the mounting seat 400 in the axial direction of the tub 200, thereby making the overall rigidity of the mounting seat 400 stronger to prevent damage caused by deformation due to vibration of the motor 300.

As shown in fig. 7 to 10, in some embodiments, the mounting base 400 is provided with a lightening hole 403, and the shape of the lightening hole 403 is set according to the outline shape of the mounting base 400, so that the lightening hole 403 is used for reducing the mass of the mounting base 400 to the greatest extent and reducing the overall strength of the mounting base 400 to the smallest extent without affecting the overall shape, rigidity and strength of the mounting base 400.

As shown in fig. 2 to 6, in some embodiments, a fixing cover 600 is further disposed on one side of the mounting base 400 away from the washing tub 200, the fixing cover 600 is coaxially disposed with the mounting base 400, a rotating shaft is disposed on the fixing cover 600 corresponding to the position of the through hole on the fixing portion 401, and the rotating shaft disposed through the fixing cover 600 is correspondingly inserted into the through hole of the fixing portion 401 and is connected with the bottom wall of the washing tub 200.

The fixing cover 600 covers the fixing portion 401 for fixing the fixing portion 401 to the bottom wall of the tub 200, thereby integrally fixing the mount 400 to the tub 200 in cooperation with the connection portion 402.

As shown in fig. 4 to 20, in some embodiments, the first connection member 700 is a rod-shaped member, the first connection member 700 is provided at one end of the tub 200 remote from the opening of the case 100, one end of the first connection member 700 is connected with the first arm of the connection part 402, and the other end of the first connection member 700 is connected with the motor 300 and extends in a direction remote from the tub 200.

The first connector 700 is made of a material with high rigidity so that the first connector 700 can resist deformation when being stressed, and materials used for the first connector 700 include, but are not limited to: metal materials, composite materials and polymeric materials; when the motor 300 transmits vibration to the tub 200 through the first link 700, the first link 700 needs to have higher rigidity to prevent damage caused by deformation due to the vibration.

The first connection member 700 is used to move the motor 300 away from the washing tub 200, and vibration generated by the start of the motor 300 is sequentially transmitted to the washing tub 200 through the first connection member 700 and the mounting base 400, so as to reduce vibration transmitted from the motor 300 to the washing tub 200.

As shown in fig. 4 to 20, in some embodiments, the second connection member 800 is a rod-shaped member, the second connection member 800 is provided at an end of the tub 200 remote from the opening of the case 100, the second connection member 800 is provided at one side of the first connection member 700, one end of the second connection member 800 is connected with the second arm of the connection part 402, and the other end of the second connection member 800 is connected with the motor 300 and extends in a direction remote from the tub 200.

The second connector 800 is made of a material that is stiff so as to provide the second connector 800 with a greater resistance to deformation when subjected to a force, and the materials used for the second connector 800 include, but are not limited to: metal materials, composite materials and polymeric materials; when the motor 300 transmits vibration to the tub 200 through the second connection 800, the second connection 800 requires higher rigidity to prevent damage caused by deformation due to the vibration.

The second connection member 800 is used for keeping the motor 300 away from the washing tub 200, and the vibration generated by the start of the motor 300 is transmitted to the washing tub 200 through the second connection member 800 and the mounting base 400 in sequence, so as to reduce the vibration transmitted from the motor 300 to the washing tub 200.

As shown in fig. 7 to 13, in some embodiments, the third connector 900 is a rod-shaped member, the third connector 900 is disposed between the first connector 700 and the second connector 800, the third connector 900 is connected to the first connector 700 and the second connector 800, respectively, and the third connector 900 is connected to the motor 300 at a position far from the middle of the connection with the first connector 700 and the second connector 800.

The third connector 900 is made of a material that is stiff so as to provide the third connector 900 with a greater resistance to deformation when subjected to a force, and the materials used for the third connector 900 include, but are not limited to: metal materials, composite materials and polymeric materials.

When the motor 300 transmits vibration to the tub 200 through the first and second connection members 700 and 800 and the third connection member 900, the third connection member 900 needs to have higher rigidity to prevent damage caused by deformation due to the vibration.

The third connecting member 900 is used for stabilizing the relative positions of the first connecting member 700 and the second connecting member 800, the vibration generated by the start of the motor 300 is transmitted to the first connecting member 700, the second connecting member 800 and the third connecting member 900, then transmitted to the mounting seat 400 by the first connecting member 700, the second connecting member 800 and the third connecting member 900, and finally transmitted to the washing tub 200 by the mounting seat 400, so as to reduce the vibration transmitted to the washing tub 200 by the motor 300.

It should be noted that, the first connector 700, the second connector 800 and the third connector 900 form a triangular vibration reduction space, the triangular vibration reduction space has strong stability, the vibration is not easily damaged, the first connector 700, the second connector 800 and the third connector 900 are not on the same horizontal plane, and the motor 300 is located in the vibration reduction space.

The joints of the motor 300 with the first and second connection members 700 and 800 and the third connection member 900 are one place, respectively, so the joints of the motor 300 with the damping space are three places for reducing the vibration transmitted from the motor 300 to the tub 200 through the damping space.

The vibration reduction space is located at one end of the first and second connection members 700 and 800 away from the washing tub 200, and after the motor 300 transmits vibration to the vibration reduction space, the vibration reduction space transmits vibration to the mounting base 400 through the first and second connection members 700 and 800, and finally the mounting base 400 transmits the vibration to the washing tub 200, thereby extending a vibration transmission path for reducing the vibration transmitted from the motor 300 to the washing tub 200.
