Benefits of technology

[0014] An object of the present invention is to provide a washing machine that can prevent laundry from projecting above a tub cover to thereby prevent water from splashing.
[0015] Another object of the present invention is to provide a washing machine that can prevent water from splashing by detecting a projection of the laundry above a tub cover and controlling a washing cycle in response to the detected signal.
[0019] In still another aspect of the present invention, there is provided a washing machine comprising: an outer tub for receiving washing water; a rotational tube rotatably installed in the outer tub; a tub cover coupled on an upper portion of the outer tub; a net formed inwardly extending from an inner circumference of the tub cover to prevent laundry from rising above the tub cover by the washing water; and a protecting cover for protecting an inner surface of the net.
[0020] In still yet another aspect of the present invention, there is provided a washing machine comprising: an outer tub; a tub cover formed on an upper portion of the outer tub; and a net formed inwardly extending from an inner circumference of the tub cover and having a plurality of passing holes, for preventing laundry from rising while allowing washing water to pass through the passing holes.
[0021] According to the present invention, since the net is formed on the tub cover, the laundry cannot be projected above the tub cover, thereby preventing the water from splashing out during the water supplying and washing cycles. Therefore, any inadvertent accident that may be caused by the splashed water can be avoided.
[0022] In addition, even when the laundry is projected above the tub cover, the detecting member detects the fact to control the RPM of the driving motor, thereby preventing the splash of the water.

Problems solved by technology

However, the permeating type washing machine has a drawback in that the water may not be fully introduced into the rotational tub as it is splashed to other directions by colliding with the laundry.
When the splashed water falls to an inner-bottom of the washing machine through a space between the outer tub and the case, it may cause an inadvertent accident such as a fire due to a short circuit between electric components.
In addition, the splashed water may pollute an outer floor around the washing machine and cause the short of washing water, making it difficult to perform the effective washing.
Even for other types of washing machines where the laundry is loaded under a water supplying hole, the water supplied through the water supplying hole may splash between the tub and the case.
The splashed water may cause a variety of problems as described above.

first embodiment

[0039] First Embodiment

[0040]FIG. 1 shows a washing machine according to a first embodiment of the present invention.

[0041] As shown in the drawing, a washing machine comprises an outer case 1 forming an outer appearance of the washing machine, an outer tub 2 disposed in the outer case 1 to receive washing water, a rotational tub 3 rotatably disposed in the outer tub 2, the rotational tub 3 being provided with a plurality of holes through which washing water can be directed to the outer tub 2, a pulsator 4 integrally formed on a center of the rotational tub 3 to rotate together with the rotational tub 3, a tub cover 5 coupled on an upper portion of the outer tub 2, a washing water supplying tube 8 on which a water supplying valve 9 is mounted to properly supply the washing water to the rotational tub 3, a washing water drain tube 6 on which a water drain valve 7 is mounted to properly drain the washing water, and a motor 13 for transmitting driving force to the rotational tub 3. In...

second embodiment

[0064] Second Embodiment

[0065]FIG. 4 shows a washing machine according to a second embodiment of the present invention.

[0066] This embodiment is identical to the first embodiment except for a structure of the net. A net 21 of this embodiment is also formed extending from an inner circumference of the tub cover 5 and is disposed under the water supplying tube 8. Each mesh of the net 21 is relatively large-sized as compared with that of the first embodiment. Therefore, the washing water is prevented from overflowing without the opened space (see 14 of FIG. 3) proposed in the first embodiment.

third embodiment

[0067] Third Embodiment

[0068]FIG. 5 shows a washing machine according to a third embodiment of the present invention.

[0069] Referring to FIG. 5, this embodiment is identical to the first embodiment except for a structure of the net. A net of the embodiment is designed such that meshes are defined by plurality of bars arranged in an identical direction, that is, one of lateral or longitudinal directions while the net of the first embodiment is designed such that the meshes are formed in a matrix shape by a plurality of bars arranged in both lateral and longitudinal directions. An opened space 34 is also provided to prevent the overflow of the water.

Abstract

Disclosed is a washing machine including an outer case, an outer tub disposed in the outer case to receive washing water, a rotational tub rotatably disposed in the outer tub, a pulsator rotating in the rotational tube to generate forced water current, a tub cover formed on an upper portion of the outer tub to guide the washing water to the rotational tub when the rotational tub and / or the pulsator rotate, a net formed on an inner circumference of the tub cover, and a motor for transmitting driving force to the rotational tub and / or the pulsator.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a washing machine, and more particularly, to a washing machine that can improve the washing reliability thereof by preventing splash of water that may be caused by collision of the water with laundry during water supplying and permeating washing cycles. [0003] 2. Description of the Related Art [0004] Generally, the washing machine is an electric apparatus used for removing dirt from laundry such as clothes, sheets and the like using a chemical reaction of the detergent as well as a mechanical action of a pulsator. General washing processes of the washing machine are comprised of an operation mode setting process automatically realized by detecting an amount and kind of laundry, a water supplying process for supplying water to a proper level in accordance with the amount and kind of laundry, and washing, rinsing and spinning processes that are controlled by a control part. [0005] The ...
