Technical field

The invention relates to a washing machine, in particular to a washing machine which can be carried around and whose barrel body and base can be separated.

Background technique

Existing washing machines can only be placed in the living room for use due to their large volume and heavy weight. Although, in recent years, some washing machine manufacturers have designed some small washing machines with small volume and light weight to meet people's requirement that some underwear that is often changed and washed can be washed instantly. But along with improving day by day of people's living standard, the people of traveling abroad is more and more, be badly in need of a kind of washing machine that can carry. But above-mentioned small-sized washing machine is an integral structure, and weight is still relatively heavy, and is not designed as portable, can only carry with both hands, thereby can not carry. At the demand of consumers, some washing machine manufacturers and some inventors have designed a kind of small in size, light in weight, and the staving and base are separated up and down and portable washing machine, so that people go out and travel. However, due to the fact that this product came out not long ago, it was found through practice that there are some imperfections, such as defects 1. The barrel and the base are two-part structure, and the inner diameter of the barrel is less than or equal to the outer diameter of the base, so when not in use When using, the base cannot be put into the staving cavity, and when carrying, it can only be carried separately, which is relatively inconvenient. Defect 2. The lower spline shaft plate is connected to the output shaft of the motor. When washing clothes, the lower spline shaft plate is socketed with the upper spline shaft sleeve, and the connection between the upper spline shaft sleeve and the pulsator shaft is the upper spline shaft plate. The internal thread of the spline sleeve is connected with the external thread of the pulsator shaft. This connection structure causes the pulsator to only rotate in one direction. The washing machine cannot be washed in an intermittent forward and reverse rotation mode, the washing form is single, and the washing effect is not good. Defect 3. The upper cover of the motor in the base is not equipped with a waterproof device, and the leaking water will easily flow into the motor shaft along the upper and lower spline shafts, and then flow into the motor from the motor shaft, causing motor failure or damage. Defect 4. There are four vertical thin ribs in the gap between the bottom surface of the barrel and the bottom of the barrel. The thickness of the ribs is only about 1mm, and the height is between 50 and 80mm, resulting in sharp upper edges and easy Clothes wear and tear, especially silk stockings can be scratched, and the thin rib sheet is also not conducive to strengthening the strength of the barrel. Defect 5, handle is a half circle, and its both sides are connected on the lug of staving top, and existing bucket handle structure is substantially identical, and appearance design is already outdated, and is not attractive in appearance. Defect 6, bung and bucket body are connected by thread, because diameter is big, switch is very laborious. For this reason, many users reflect opinions, hope to overcome above-mentioned defect, look forward to designing a kind of novel portable washing machine as soon as possible, to satisfy people's needs.
