Japanese Patent Application Laid-Open No. 2008-220601

In such a washing machine, a door portion is arranged outside the opening, and a facing portion facing the door portion is provided at the edge of the opening. The washing machine is provided with a structure for reducing the leakage of water from between the door portion and the facing portion to the outside of the washing machine. However, although it is a small amount, water may enter the facing portion or water droplets may occur in the facing portion. Configuration required. For this reason, the main body forming the washing chamber is formed with a projecting portion projecting toward the door portion at the lower end of the door portion and extending in the horizontal direction from one facing portion to the other facing portion. there is

However, although such an overhanging portion can catch water falling down along the facing portion, it is easy for water to enter from the washing chamber side during washing or rinsing, and also has a structure to receive the facing portion. In addition, water sometimes splashes out of the machine from the ends in the extending direction of the overhanging portion that communicates with the outside of the machine.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a washing machine capable of reducing the amount of water splashing out of the machine from the ends in the extending direction of the projecting portion.

The washing machine of the present invention includes a main body portion having a washing chamber for containing objects to be washed and an opening for inserting and removing the objects to be washed into and out of the washing chamber; a door portion, wherein the body portion includes a pair of opposing portions provided along the edge of the opening in a vertical direction so as to face the door portion in the closed state; and the door portion in the closed state. and a projecting portion extending substantially horizontally so as to project outside the opening along the lower end of the portion, and the projecting portion has opposite ends in the extending direction to the pair of opposing portions. A pair of opposing regions are formed, and the projecting portion is provided with a plate-like closing plate that shields at least a portion of a communicating portion that communicates from the washing chamber to at least one of the pair of opposing regions.

In the washing machine with this configuration, a plate-shaped closing plate is provided to block at least a part of the communicating portion that communicates from the washing chamber to the opposing area, so that it is possible to suppress water from entering the opposing area from the cleaning chamber. . As a result, it is possible to reduce the amount of water that has entered the opposing area from the cleaning chamber and jumps out from the ends in the extending direction of the projecting portion.

In the cleaning machine of the present invention, a gap may be formed between the bottom of the overhang and the lower end of the closing plate. With this configuration, water collected at the lower end of the projecting portion along the opposing portion can be guided toward the cleaning chamber, so that water can be prevented from accumulating at the lower end of the opposing portion. In addition, in such a washing machine, high-temperature water is sprayed during washing, and the pressure in the washing chamber increases. The pressure in the cleaning chamber can be released to the outside from a portion of the main body that communicates with the outside of the main body.

The washing machine of the present invention further comprises a nozzle that is arranged in the washing chamber and rotates in one direction to inject water, and the blocking plate is located on the side that coincides with the rotation direction of the nozzle in the extending direction of the overhang. You may provide with respect to an opposing area|region. The rotation direction here means the rotation direction of the nozzle in the region adjacent to the overhanging portion, and the rotation direction in the portion where the nozzle rotates along the extending direction of the overhanging portion. In the washing machine having such a configuration, the water sprayed from the unidirectionally rotating nozzle is splashed along the tangential direction of the rotating circle. For this reason, in the projecting portion extending in one direction, there is a tendency that water tends to accumulate in the facing area on the side in which the water is scattered. In this configuration, since the blocking plate is provided on the side in which the water is scattered, it is possible to effectively prevent the water jetted from the nozzles from entering the opposing area.

The washing machine of the present invention further comprises a washing tank arranged in the lower region of the washing chamber, and the reservoir for storing washing water in the washing tank is arranged so that the longitudinal direction is perpendicular to the extending direction, and It may be arranged in the lower region so as to be biased toward the rotation direction side of the nozzle in the extension direction. In the washing machine having such a configuration, the water sprayed from the unidirectionally rotating nozzle is splashed along the tangential direction of the rotating circle. For this reason, in the projecting portion extending in one direction, there is a tendency for water to easily collide with the blocking plate arranged on the side in which the water is scattered. In this configuration, the storage portion of the cleaning tank is arranged in a state biased toward the direction in which water is splashed in the lower region of the cleaning chamber 1B. As a result, the reservoir of the cleaning tank can be arranged at a position relatively close to the closing plate where the water jetted from the nozzle is likely to collide. As a result, the water blocked from entering the facing area by the blocking plate can be efficiently guided to the reservoir of the cleaning tank, and water can be prevented from accumulating in the facing area.

According to the present invention, it is possible to reduce the amount of water splashing out of the machine from the ends in the extending direction of the overhanging part.

By adopting such a configuration, it is possible to prevent water from entering the discharge hole 23d during washing and flowing back to the rinsing tank 6 without providing a backflow prevention mechanism in the discharge hole 23d, thereby reducing costs. .

Next, the effect of the dishwasher 100 of the said embodiment is demonstrated. In the dishwasher 100 of the above-described embodiment, the plate-shaped closing plate 18 is provided to block at least a part of the communicating portion C communicating from the washing chamber 1B to the facing area A. can prevent water from entering the As a result, it is possible to reduce the amount of water that has entered the opposing area A from the cleaning chamber 1B and escape from the side ends 17a and 17b in the extending direction of the overhanging portion 17. As shown in FIG.

In the dishwasher 100 of the above embodiment, a gap G is formed between the bottom portion 17d of the projecting portion 17 and the lower end portion 18c of the closing plate 18. As shown in FIG. As a result, the water collected at the lower end of the facing portion 16 of the overhanging portion 17 along the facing portion 16 of the main body 1 can be guided toward the washing chamber 1B, thereby preventing water from accumulating at the lower end of the facing portion 16. can be suppressed.

Further, in the configuration in which the protruding portion 17 is provided along the lower end of the door portion 15, although it is possible to catch water falling along the facing portion 16 of the main body portion 1, it is close to the rotating door portion 15. The overhang 17 cannot be installed so as to touch. Therefore, the projecting portion 17 has portions communicating with the outside of the main body portion 1 (outside the machine) at, for example, the side ends 17a and 17b, which are the ends in the extending direction. In the dishwasher 100, high-temperature water is jetted during washing to increase the pressure inside the washing chamber 1B, but the pressure can be released to the outside through the above-described portion communicating with the outside. Since the above-described gap G is provided in the dishwasher 100 of the above-described embodiment, the pressure can be released to the outside through the gap G and the part communicating with the outside.

Further, in the dishwasher 100 of the above embodiment, as shown in FIG. 3, the water jetted from the lower nozzle 4 rotating in one direction is splashed along the tangential direction of the rotating circle. Therefore, in the vicinity of the projecting portion 17 extending in one direction on the front side of the dishwasher 100, the water jetted from the lower nozzle 4 is directed to the right side as viewed from the washing chamber 1B side, and the front side of the dishwasher 100. Water is splashed on the left side as seen from the Therefore, the projecting portion 17 tends to hit the closing plate 18 on the side in which water is scattered (right side when viewed from the washing chamber 1B side, left side when viewed from the front of the dishwasher 100).

In the dishwasher 100 of the present embodiment, the storage portion 22 of the washing tank 20 has a longitudinal direction orthogonal to the left-right direction (extending direction of the projecting portion), and the lower nozzle in the left-right direction. 4 in the lower region of the cleaning chamber 1B. As a result, the inner surface of the side portion 20c connected to the bottom portion 20a of the reservoir portion 22 of the cleaning tank 20 can be placed relatively close to the closing plate 18 where the water jetted from the lower nozzle 4 is likely to collide. As a result, the water blocked from entering the facing area A by the blocking plate 18 can be efficiently guided to the storage part 22 of the cleaning tank 20, and the accumulation of water in the facing area A can be suppressed. As shown in FIG. 3, the cleaning tank 20 has a shallow recessed portion from above and a deep recessed portion recessed downward from the shallow recessed portion. The shallow recess separates the machine room 1A from the washing room 1B, receives the water jetted from the upper nozzle 3 and the lower nozzle 4, and guides it to the deep recess after washing or rinsing the tableware D. The deep recessed portion is a portion for storing cleaning water supplied to the upper nozzle 3 and the lower nozzle 4 by the cleaning pump 5 . The reservoir 22 in this embodiment corresponds to the above-described deep recessed portion.

Although one embodiment has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the scope of the invention.
