In another embodiment of the present utility model, the extension 331 is a tight or interference fit with the second opening 12021. In the use process of the washing machine, vibration in the up-down direction is not only generated, but also transverse vibration exists, the extension section 331 is tightly matched or in interference fit with the second opening 12021, so that a moving gap of the bottom foot 3 relative to the base 12 in the transverse direction is zero, the bottom foot 3 and the base 12 cannot move transversely, the bottom foot 3 can absorb the transverse vibration of the base 12 to the greatest extent, and the use stability of the washing machine is improved.

Referring to fig. 11, the first mounting cavity side wall 12012 has a second bottom surface 120121, the second bottom surface 120121 is located at the bottom of the first mounting cavity side wall 12012, and a first gap 41 is provided between the top of the support portion 32 and the second bottom surface 120121. The top of supporting part 32 has first top surface 321, has first clearance 41 between first top surface 321 and the second bottom surface 120121, and first clearance 41's setting makes when the footing 3 is bearing (including washing machine weight, clothing weight, water weight etc.) first installation cavity lateral wall 12012 can not take place the transmission of power with supporting part 32, and first installation cavity lateral wall 12012 is as the weaker position of intensity on the base 12, does not bear gravity, prevents that first installation cavity lateral wall 12012 atress from damaging, influences washing machine's normal use. In addition, the first gap 41 prevents the supporting portion 32 from contacting the base 12, and the foot 3 is inclined when the washing machine is dragged, but the supporting portion 32 does not contact the base 12, so that the first installation cavity side wall 12012 is not dragged by the supporting portion 32 in the transverse direction, and the first installation cavity side wall 12012 is protected from being damaged. The first gap may be set above 0.5 mm. The first gap 41 is too small and the first gap 41 is reduced to contact the first mounting chamber sidewall 12012 during the dragging of the washing machine.

Referring to fig. 11, the main body portion outer side wall 311 and the inner side surface 120122 of the first mounting chamber side wall 12012 have the second gap 42, and the second gap 42 becomes gradually larger from top to bottom. The bottom foot 3 is inclined when the washing machine is dragged, the main body part 31 is inclined, in order to prevent the lateral wall 12012 of the first installation cavity from being damaged by the lateral force of the main body part 31, the second gap 42 is gradually enlarged from top to bottom according to the inclination degree of the main body part 31, a certain moving space is reserved for the main body part 31 relative to the lateral wall 12012 of the first installation cavity, but the gap between the part of the main body part 31 positioned above and the inner side surface 120122 of the lateral wall 12012 of the first installation cavity is reduced as much as possible, so that the moving space of the bottom foot 3 relative to the base 12 in the lateral direction is controlled, the lateral relative movement between the bottom foot 3 and the base 12 is prevented, the bottom foot 3 can absorb the lateral vibration of the base 12 to the greatest extent, and the service stability of the washing machine is improved.

Referring to fig. 12, the supporting portion 32 has a third bottom surface 321 at the bottom thereof, and a first groove 3211 is formed in the third bottom surface 321. The provision of the first grooves 3211 increases the friction coefficient between the third bottom surface 321 of the supporting part 32 and the ground, and increases the sliding resistance of the supporting part 32 with respect to the ground, thereby improving the stability of the washing machine when it is placed on the ground.

Referring to fig. 12, a first blind hole 3212 is formed at a center of the third bottom 321. The arrangement of the first blind hole 3212 reduces the stress area of the supporting part 32 as a whole, improves the pressure intensity of the third bottom surface 321, improves the resistance to be overcome by moving the washing machine, and further improves the stability of the washing machine placed on the ground.

As another illustrative embodiment of the utility model, the outer diameter of the support portion 32 is greater than the outer diameter of the first mounting cavity sidewall 12012.
