Description

Washing machine with pumping function

The present invention relates to a washing machine having a pumping function, and more particularly, to a washing machine having a pumping function for washing laundry by pumping using a cylinder and a piston.

Washing machines are classified into drum type, stirring type, and vortex type according to the washing method.

In the drum type, laundry is put inside a drum with several protrusions and rotated, and the laundry is washed by the impact of falling from top to bottom. And, the vortex type is a method in which the pulsator installed in the lower part of the washing tub rotates and generates a water current, and the washing is performed due to the water current.

In general, a vortex washing machine is widely used because it has good washing efficiency and low power consumption. However, there is a problem in that the washing is not uniform and the fabric is tangled or damaged by the rotating water current.

Therefore, in order to solve the above problems, there is a need for a washing machine that performs washing uniformly and does not damage clothes.

In the prior art, Korean Patent Registration No. 10-1130480 (laundry striking body of a drum washing machine) has been disclosed.

In order to solve the above problems, the present invention uses a pumping function rather than a method of washing with water generated by a pulsator with respect to a washing machine for washing laundry, so that the washing is uniform and the clothes are not damaged. There is this.

In a washing machine having a pumping function according to an embodiment of the present invention for solving the above problems, there is provided a washing machine, comprising: an inner container for accommodating laundry and supplying detergent mixed with water and detergent to wash the laundry; an outer tube for discharging water from the inner tube during dehydration operation; one or more cylinders located above the inner cylinder, including a pumping unit for repeatedly pumping and washing the laundry accommodated in the inner cylinder, the pumping unit being installed to have a length in the vertical direction; Pistons respectively installed in the cylinder to reciprocate in the vertical direction; It may include a pumping plate coupled to the lower end of the piston for pumping laundry to wash.

In addition, the inner cylinder is spaced apart along a circumferential surface and a plurality of friction protrusions formed to be spaced apart from each other on the inner surface, and may include a drain hole for discharging water from the inner cylinder during dehydration.

In addition, the inner cylinder includes a small strike band distributed on the side surface, the small strike band is located eccentrically to hit the laundry by rotational power; a power transmission unit for transmitting rotational power to the striking unit; It may include a power unit for providing rotational power.

In addition, the pumping unit is located on the upper side of the inner cylinder, the one or more cylinders may further include a rotating plate and a gear unit for rotating the rotating plate.

In addition, it may be formed of the same material as the piston and may be integrally formed or may be characterized in that it is coupled to the piston and a coupling portion.

Since the washing machine having the pumping function according to the above embodiment of the present invention pumps laundry using a pumping plate that moves up and down, washing power is increased compared to the conventional washing machine.

In addition, the small strike band according to an embodiment of the present invention is formed along the circumferential surface of the inner cylinder, so that when laundry is attached to the inner cylinder circumference, it is dropped or mixed so that the laundry is not located only in the same place, and the laundry is washed. It has the effect of being able to wash evenly without any deviation.

In addition, the pumping unit according to an embodiment of the present invention is equipped with a rotation function, so that it can create a current instead of a pulsator role, and because it hits the laundry while rotating, the striking force is increased, so that the washing power can also be increased.

A sensor may be installed on the pumping plate 430 , and is interlocked with the controller 130 . The sensor may measure the distance between the pumping unit 400 and the laundry in the inner tube 200 to detect the amount of laundry in the inner tube 200 accordingly. Accordingly, the controller 130 may control the pumping distance by the pumping plate 430 according to the amount of laundry.

Referring to FIG. 10 , the pumping plate 430 may pump and wash laundry in the inner tube 200 . First, the piston 420 reciprocates in the vertical direction by the power of the cylinder 410, and at this time, the pumping plate 430 connected to the piston 420 also reciprocates in the vertical direction as well, so that the laundry can be pumped and washed.

11 and 12 , the pumping unit 400 may be installed to enable a rotation function.

More specifically, a configuration in which the pumping unit 400 is provided to enable a rotation function may include a rotation motor 440 and a gear unit 450 .

The rotation motor 440 may generate rotational power so that the rotation plate 451 may rotate. At this time, the rotary motor 440 is preferably formed in a fixed state next to the gear unit 450, but is not limited thereto.

The gear unit 450 is configured to transmit power generated from the rotation motor 440 so that the pumping unit 400 can rotate.

Meanwhile, the pumping unit 400 can pump and wash laundry while rotating, thereby increasing the power of pumping the laundry. Accordingly, when washing laundry that is bulky or requires strong pressure, such as a duvet, it is possible to increase the washing rate.

In addition, the pumping unit 400 may be capable of high-speed rotation without a pumping motion. Accordingly, a strong current can be generated in the inner cylinder 200, and washing can be performed even with the current.

Referring to FIG. 13 , the rotation plate 451 appears to be large enough to affect the inner cylinder 200 when it rotates, but it is only an embodiment of the present invention for better understanding, so it does not affect the inner cylinder 200 . It may be formed in any size.

Referring to FIG. 14 , the pumping plate 430 may include a pressing protrusion 431 on its lower surface.

When the pumping plate 430 pumps and washes the laundry, the pressing protrusion 431 has a function of increasing the washing rate by increasing the contact surface with the laundry.

Referring to the drawings, the pressing protrusion 431 may be configured in a hemispherical shape in which the protruding portion is round, but it is not limited thereto, and may be configured in various other shapes because it is only an embodiment of the present invention for better understanding.

When washing using the up-and-down movement of the pumping part, synergy is created between the pressure protrusion 431 formed on the lower surface of the pumping plate 430 and the friction protrusion 301 on the inner surface of the inner cylinder 200, so that the contact surface with the laundry rises dramatically. It can have the effect of increasing the rate further.

Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those of ordinary skill in the art to which the present invention pertains can practice the present invention in other specific forms without changing the technical spirit or essential features of the present invention. you will be able to understand Accordingly, the embodiments described above are illustrative in all respects and not restrictive.
