Description

Washing machine with lifting type dewatering barrel

Technical Field

The utility model belongs to the technical field of domestic appliance's product technology and specifically relates to a washing machine with lift formula dewatering barrel.

Background

Washing machines are cleaning appliances that wash laundry using mechanical action of electricity generation, and are classified into two categories, a household category and a collection category, according to their rated washing capacities.

The household washing machine mainly comprises a box body, washing dehydration barrels (some washing and dehydration barrels are separated), a transmission and control system and the like, and some washing machines are also provided with a heating device. Washing machines are generally intended to use water as the main cleaning liquid, as opposed to special cleaning solutions, and dry cleaning, which is usually carried out by specialists.

Common household washing machines are mainly classified into pulsator washing machines and drum washing machines.

The drum washing machine originates from Europe, the washing method is designed by simulating the principle that a hammer strikes clothes, and the drum washing machine is composed of a stainless steel inner drum, a mechanical program controller, a shell protected by three steps of phosphorization, electrophoresis and spraying, and a plurality of heavy cement blocks, wherein the heavy cement blocks are used for balancing the huge centrifugal force generated when the drum rotates to do repeated motion, and the clothes are washed cleanly under the combined action of washing powder and water.

The pulsator washing machine is another type of washing machine, and a motor drives a pulsator to rotate, so that clothes continuously roll up and down along with water. The clothes washing machine has a single barrel, a double barrel and the like. Its structure is simple, maintenance is convenient, cleaning rate is high, but its wear rate to clothes is high and water consumption is high. With the development of science and technology, a new water flow washing machine controlled by a computer is developed, and a large impeller, a concave impeller and the like are adopted. Has the advantages of small winding on clothes, uniform washing and low clothes loss rate; the washing cylinder body is made of four types, namely full plastic, enamel, aluminum alloy and stainless steel. The working principle of the pulsator washing machine is as follows: the clothes are driven to turn over continuously up, down, left and right by the forward and reverse rotation of the impeller arranged at the bottom of the washing bucket, so that the clothes and the wall of the bucket are rubbed softly in water, and the decontamination and the cleaning are realized under the action of a detergent.

The impeller type washing machine is invented by Japanese, is a typical Japanese machine, modern people wash clothes commonly using cold water, on the premise of being used to use the cold water, the drum type washing machine does not have the washing cleanness of an impeller, and certainly, an electric auxiliary heating function can be used when the drum type washing machine is used, but the drum type washing machine needs longer time, modern people ask for the life efficiency, are busy at ordinary times, have narrow living space, do not occupy the space and can move, and the drum can not be moved at all, so the impeller type washing machine is used firmly.

For example, patent document CN103015114B discloses a pressure-driven washing machine, in which a pressure lever is made into an internal screw type double-head arrangement, and the rotation directions of the two heads are opposite; the washing machine body is provided with double barrels which are divided into a washing barrel and a spin dryer tube, the upper openings of the washing barrel and the spin dryer tube are provided with covers, and a bearing is arranged in the center of the cover plate. The bottom of the washing barrel is provided with a wave wheel and an upright post, the barrel wall of the washing barrel is provided with a clothes guide plate which is upward along a spiral line, the bottom of the spin-drying barrel is provided with a spin-drying barrel and an upright post, when the washing machine is used, wet clothes which are well washed are uniformly placed into the spin-drying barrel, the press rod penetrates through a bearing hole of the cover plate and is sleeved on the upright post of the spin-drying barrel, and the press rod is continuously pushed downwards to enable the spin-drying barrel to rotate quickly and spin-dry the clothes, so that the purposes of hand washing free and power and water saving are achieved.

The most classical and extensive pulsator washing machine of the patent products has a double-barrel structure, wherein one barrel is used for washing (adding water), the other barrel is used for spin-drying (not adding water), and the spin-drying after washing needs to be carried out by people for taking and placing operations, which means that people need to stare at the machine, and the effect of washing and spin-drying in one step cannot be achieved.

If the washing and spin-drying are made into a single-barrel form, the required effects are as follows: during washing, the impeller rotates relative to the shell to stir water flow and clothes, and the spin dryer tube keeps static relative to the shell; during spin-drying, the spin dryer tube needs to rotate relative to the shell, the impeller can rotate or can not rotate, and water in clothes is thrown outwards through the rotating centrifugal force of the spin dryer tube, so that the aim of spin-drying is fulfilled. Therefore, two sets of power systems are often needed to be arranged to respectively control the operation of the impeller and the spin dryer tube, but the cost is greatly increased on one hand, and the structure is more complex and occupies a large amount of space on the other hand.

Therefore, a single-tub pulsator washing machine which can achieve washing and spin-drying functions by a single set of driving device is urgently needed.
