This application claims the benefit of Korean Application No. 10-2005-0006622, filed on Jan. 25, 2005, which is hereby incorporated by reference as if fully set forth herein.
1. Field of the Invention
The present invention relates to a detergent box in a washing machine, and more particularly, to a detergent box in which a structure of the detergent box to be placed in a front of the washing machine is modified for preventing the detergent box from falling off even if the washing machine is tilted or shaken, and enabling a user to make an easy notice of proper placement of the detergent box.
2. Discussion of the Related Art
In general, the washing machine removes dirt from clothes or beddings (hereafter called as laundry) by using action of detergent and water (hereafter called as ‘washing water’). In the washing machines, there are agitator type, pulsator type, and drum type washing machines.
The agitator type washing machine washes by rotating an upstanding washing pole at a center of an inner tub in both directions. The pulsator type washing machine washes by using friction between a water circulation and laundry taken place as a pulsator of a disk shape on a bottom of an inside of an inner tub is rotated in both directions. The drum type washing machine washes by putting washing water, detergent and laundry in a drum having a plurality of lifts projected from an inside surface and rotating the drum.
A related art drum type washing machine is provided with a body, a drum in the body for rotating laundry held therein, a detergent box over the drum for holding detergent, and a motor for rotating the drum. The detergent box is connected to the drum with a bellows for supplying the detergent from the detergent box to the drum.
In the meantime, the detergent box is placed in a dispenser in the cabinet of the drum type washing machine. A related art detergent box has a projection at one side, and the dispenser has a recess in one side opposite to the projection, for preventing the detergent box from being moved backward once the detergent box is placed in the dispenser, even if the washing machine is tilted, or vibrates due to rotation of the drum.
However, the falling off preventive structure formed at the related art detergent box and the dispenser has a problem in that the projection on the detergent box is worn down as a process is repeated, in which the detergent is put in after pulling and opening the detergent box, and closed again. Moreover, as the projection is worn down, there has been no way for determining whether the detergent box is placed in completely, or not.
The present invention is directed to a detergent box that substantially obviates one or more problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a detergent box in a washing machine having a falling off preventive structure which is not liable to be worn down even if the detergent box repeats an opening/closing operation.
Another object of the present invention is to provide a detergent box in a washing machine which enables to determine whether the detergent box is placed in fully or not by means of sound or feeling.
Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
The detergent box of the present invention includes a stopper to be seated in the recess, and an rib for providing an elastic force to the stopper.
The detergent box holds the detergent, and the dispenser is mounted in the washing machine for placing the detergent box therein. The dispenser has a recess for seating the stopper therein as the detergent box is placed in the dispenser.
The rib provides an elastic force to the stopper. For providing a comparatively soft elastic force, the rib has an elastic slot near the stopper.
It is preferable that the rib is formed at a top of each side of the detergent box, to provide an appropriate elastic force by being bended. It is preferable that the stopper is projected downward from the rib.
The rib provides an elastic force to the stopper in up/down directions by being bended. If the rib can not be extended adequately in a lateral direction of the detergent box due to spatial restriction, to shorten a moment arm of the bending, the rib fails to secure an appropriate flexibility. By forming the elastic slot in the rib, a required appropriate flexibility can be secured.
The elastic slot may have any shape as far as it is to the purpose. The elastic slot may not pass through the rib in a vertical direction. However, it is preferable because fabrication of the slot is easy.
When the detergent box is being inserted into the dispenser, the stopper is compressed and slides along a surface of the dispenser having the recess formed therein, and when the stopper arrives to the recess, the stopper is seated in the recess as the compression of the stopper is released.
At the time the stopper is seated in the recess, a sound may be generated because the stopper may hit an inside of the recess as the compression of the stopper is released suddenly. Moreover, the vibration from sudden movement of the stopper can be transmitted to a hand of the user which is holding the detergent box handle. Such as sound or feeling from the vibration enables the user to notice that the detergent box has been placed, properly.
It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the invention and together with the description serve to explain the principle of the invention. In the drawings;
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
Referring to
According to above configuration, after opening the door 120 and introducing the laundry into the drum 140, the user applies washing conditions to operation devices on the control panel 150. Then, upon pressing a start button, the washing water is supplied through the water supply valve 160, and introduced to the detergent holding unit 200 through the water supply pipe 180. The washing water is mixed with the detergent at the detergent holding unit 200, and the washing water mixed with the detergent is introduced to the tub 130 and the drum 140 through the bellows 170. When a water level of the washing water reaches to a preset level, the supply of washing water is stopped, and the drum 140 is rotated to start washing.
Referring to
The dispenser 220 can be securely mounted in the cabinet 110, and the detergent box 210 can be placed in the dispenser 220 or drawn a predetermined distance out of the dispenser 220. The detergent box 210 has a falling off preventive portion 214 (see
According to above configuration, after the user pulls out the detergent box 210 for a predetermined distance before starting the washing, fills the detergent in the detergent box 210. Then, the user pushes the detergent box 210 into the dispenser 220 again.
Referring to
In detail, in the cover front 211, there is a handle 211a for the user to put fingers therein and pull the detergent box 210 forward. Moreover, the box body 212 includes a bleaching agent holding portion 213, and a detergent holding portion 215 each recessed to a predetermined depth, and partitioned at a predetermined distance, and a falling off preventive portion 214 mounted between the bleaching agent holding portion 213 and the detergent holding portion 215, for preventing the detergent box 210 from falling off the dispenser 200, completely.
Moreover, the box body 212 includes ribs 216 each extended along a side edge for smooth sliding of the detergent box 210 into the dispenser 220, and push down projections 217 projected upward from the ribs 216 by predetermined heights, respectively. In detail, for preventing a top surface of the cover front 211 and a top cover (not shown) of the washing machine 100 from interfering with each other in a process the detergent box 210 is placed into the washing machine, the push down projections 217 press the detergent box 210 downward, slightly.
Moreover, there are stoppers 218 projected down from front and/or rear of the push down projections 217, respectively. At one side of the rib 216, there is an elastic slot 219 cut away at predetermined width and length.
In detail, the stopper 218 is placed in a recess 223 (see
In the meantime, the elastic slot 219 at one side of the rib 216 having the stopper 218 formed thereon enables to prevent the stopper 218 from wearing down during the stopper 218 is placed in the recess 223. In other words, the stopper 218 is bent upward slightly in a process the stopper 218 moves along the side of the dispenser body 221 until the stopper 218 reaches to the recess 223 when the stopper 218 returns to an original state of a horizontal position. According to this, the wear down of a tip of the stopper 218 can be prevented.
Referring to
In detail, the rib 216 of the detergent box 210 is inserted between the dispenser cover 221 and the top of the side of the dispenser body 222. In more detail, when the detergent box 210 is inserted through the opening 114, the rib 116 slides in through the top of the side of the dispenser body 222. Then, if the detergent box 210 is pushed in until ‘click’ sounds as the stopper 218 seats in the recess 223, the detergent box 210 is inserted, fully. Then, the cover front 211 is brought into close contact to a cover front contact surface 115 around the opening 114.
Thus, as the detergent box 210 is placed in the dispenser 220 fully, even if the washing machine is tilted in the middle of washing, the move out of the detergent box 210 is prevented. Moreover, the determination of the full placement of the detergent box 210 in the washing machine can be made with easy.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. Thus, it is intended that the present invention covers the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
