The present invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.
-
FIG. 1 is a perspective view illustrating a dishwasher according to an embodiment of the present invention. - The dishwasher according to the embodiment of the present invention includes a
case 100, which provides a washing space and has an opening surface, arack 200 which is provided in thecase 100 to provide a storage space for washing objects, and adoor 300, which opens and closes the opening surface and withdraws therack 200 from thecase 100. - The front portion of the
door 300 is provided with acontrol panel 320, through which a user inputs the operations of the dishwasher, and ahandle 310 for withdrawing therack 200. - That is, the user may input the operations of the dishwasher to the
control panel 320 provided on the front portion of thedoor 300, and may withdraw thedoor 300 from thecase 100 by pulling thehandle 310 provided on the front portion of thedoor 300. - When the
door 300 is withdrawn from thecase 100, therack 200 is exposed to the outside of thecase 100 and thus dishes intended to be washed may be seated in therack 200. - The dishwasher has a structure in which, after the dishes are seated in the
rack 200 and thedoor 300 is inserted into thecase 100, the dishes may be washed through the input of operation conditions to thecontrol panel 320. -
FIG. 2 is a view illustrating the top, side, and front of the dishwasher in which therack 200 is inserted into thecase 100, according to the embodiment of the present invention. - As illustrated in
FIG. 2 , each of thecase 100 and therack 200 has a length L2 longer than a width L1 thereof. Since an existing rectangular dishwasher having the same width L1 and length L2 occupies a certain space regardless of the shape of a sink, it is difficult for a user to determine the position or direction of the dishwasher. However, since the present invention provides a rectangular dishwasher having a length L2 longer than a width L1 thereof, it is possible to install the dishwasher in the state in which the rear surface of the dishwasher is fixed to the wall according to the structure of the sink, or in the state in which the side surface thereof is fixed to the wall, as the occasion demands. - Dishes may be immediately accommodated in the dishwasher to be washed, but are often accommodated in the dishwasher after simply rinsing the dishes with water, i.e. so-called rough washing, so as to be secondarily washed.
- The dishwasher of the present invention has the
door 300 which may be inserted into and withdrawn from the dishwasher in the longitudinal direction thereof. Therefore, after roughly washing dishes in the state in which thedoor 300 of the dishwasher is directed toward the sink, the user can accommodate the dishes immediately in the dishwasher, with no need for a separate receiving device. - Accordingly, it is possible to resolve the inconvenience whereby the user stores dishes that have been roughly washed in a different place, and a kitchen region can be efficiently utilized since there is no need for a separate receiving device.
-
FIG. 3 is a perspective view illustrating therack 200 of the dishwasher according to the embodiment of the present invention. - A first washing object S1 illustrated in the drawing refers to a dish having a circular bottom. For example, the first washing object S1 includes a cup, a bowl, and the like.
- A second washing object S2 refers to a dish having a diameter greater than a height thereof. For example, the second washing object S2 includes plates.
- The
rack 200 includes afirst accommodation section 210 for accommodating the first washing object and asecond accommodation section 220 for accommodating the second washing object. - The
second accommodation section 220 may have asupport portion 221 protruding from the lower end thereof, and thesupport portion 221 serves to prevent the second washing object from falling by supporting the lower portion of the second washing object having the diameter greater than the height thereof. - The
support portion 221 is preferably configured as at least two support portions, but the present invention is not limited thereto. The number ofsupport portions 221 may vary according to the design of therack 200. - The
first accommodation section 210 may include afirst guide 211 which is located inside the first washing object, and asecond guide 212 which receives the outer peripheral surface of the first washing object. - The
first guide 211 preferably has an opened center such that wash water sprayed by afirst injection section 410, which will be described later, is sprayed into the first washing object. For example, thefirst guide 211 may have a ring shape as illustrated inFIG. 3 . The ring shape is only by way of example, and the present invention is not limited thereto. The shape of thefirst guide 211 may be changed. In addition, since the center of thefirst guide 211 is opened, the wash water sprayed from thefirst injection section 410 can be easily sprayed into the first washing object. - A portion of the
second guide 212 has the same shape as that of thefirst guide 211 in order to avoid interference with the shape of thefirst guide 211, and thesecond guide 212 is spaced apart from thefirst guide 211 by a predetermined distance. For example, when thefirst guide 211 has the ring shape as in the embodiment and thesecond guide 212 has a linear shape, interference occurs between the first andsecond guides second guide 212 must have the same shape as thefirst guide 211 and thesecond guide 212 must be spaced apart from thefirst guide 211 by a predetermined distance. - In addition, a
first injection section 410 for spraying wash water to thefirst accommodation section 210 is provided at the lower end of thefirst accommodation section 210, and asecond injection section 420 for spraying wash water to thesecond accommodation section 220 is provided at the lower end of thesecond accommodation section 220. -
FIG. 4 illustrates that the first washing object is provided in thefirst accommodation section 210 of therack 200. - The
first injection section 410 is provided at the lower end of thefirst accommodation section 210 of therack 200, and includes a hemisphericalmain body 411 protruding from the lower portion of thecase 100, and at least twoinjection holes 412 provided in themain body 411 such that wash water is sprayed at different angles of injection. - The wash water sprayed from the
first injection section 410 is sprayed into the first washing object at two or more angles of injection by the injection holes 412. - In the first washing object, having the circular bottom, such as a cup, typically, the outer portion of the washing object is easily washed, but it is difficult to wash the inner portion of the washing object. This is because wash water has to be sprayed at various angles and to a high position in order to easily wash the upper end of the inner surface of the first washing object.
- Thus, when the dishwasher of the present invention has the configurations of the
first accommodation section 210 and thefirst injection section 410, wash water may be evenly sprayed to the inner surface of the first washing object through thevarious injection holes 412, which have different angles of injection, provided in themain body 411 of thefirst injection section 410. In addition, when wash water is sprayed at a high pressure and the injection holes 412 have a small size, the injection height of wash water may be sufficiently increased. Consequently, the upper end of the inner surface of the first washing object can also be washed. -
FIG. 5 is a front view illustrating thefirst injection section 410. - The
first injection section 410 is provided at the lower end of thefirst accommodation section 210. As described above, thefirst injection section 410 preferably includes themain body 411 and two or more injection holes 412 having different angles of injection, in order to spray wash water to the inner surface of the first washing object. -
FIG. 6 is a front view illustrating thesecond injection section 420. - The
second injection section 420 is provided at the lower end of thesecond accommodation section 220. In contrast to the first washing object, it is important that opposite side surfaces of the second washing object are washed since the second washing object does not have an inner surface. Thus, it is preferable that thesecond injection section 420 is rotatably provided to evenly wash the opposite side surfaces of the second washing object. -
FIG. 7 is a front view illustrating a dishwasher including afirst injection section 410, asecond injection section 420, and athird injection section 430. - The dishwasher of the present invention includes an
injection section 400. Theinjection section 400 is configured of three injection sections having different functions. - The
injection section 400 is divided into afirst injection section 410, asecond injection section 420, and athird injection section 430, and respective detailed descriptions thereof will be given below. - The first and
second injection sections second accommodation sections third injection section 430 provided on the inner surface of acase 100 sprays wash water in a direction perpendicular to the height direction of thecase 100. - The
third injection section 430 may be provided so as to spray wash water to the first andsecond accommodation sections case 100. Thethird injection section 430 may be configured as a plurality of injection sections in the height direction of thecase 100. - The above-mentioned conventional dishwasher has the structure in which wash water is sprayed in a one-dimensional manner so as to wash dishes. In contrast, in the dishwasher of the present invention, wash water, which is sprayed from each of the first and
second injection sections case 100, defines a first axis, and wash water, which is sprayed from each of thethird injection sections 430 provided on opposite side surfaces of thecase 100 in the height and vertical directions, defines a second axis. Furthermore, when thethird injection section 430 is provided on the rear surface facing the opening surface of thecase 100, a third axis, which is perpendicular to both of the first and second axes, is defined. Consequently, the wash water may be sprayed in a three-dimensional manner. - As a result, since the wash water is sprayed onto all surfaces of the washing object, it is possible to improve the ability to wash dishes.
