Description

Technical Field

[0001] The utility model relates to the technical field of dishwashers, in particular to a sink-type washing machine for washing tableware, fruits and vegetables. Background Art

[0002] A sink-type washing machine usually adopts an upward-turning door body, and the switch assembly of the washing machine is usually installed on the door body to facilitate user operation. For example, Chinese utility model patent ZL 202321042974.7 "A sink-type washing machine" discloses a sink-type dishwasher including a door body structure.

[0003] For the above-mentioned sink dishwasher with a sunken platform-mounted door body, the functional tank and the water sink are welded to each other to form a central beam in the middle, and the door body of the functional tank is installed in the sunken platform of the functional tank panel. The sunken platform space of the functional tank panel is relatively independent and not connected to the sunken platform space of the water sink.

[0004] In the process of daily use of the sink-type dishwasher adopting the above-mentioned structure, water will inevitably accumulate on the door body. The accumulated water will easily flow into the functional tank along the gap between the door body and the functional tank panel sink, contaminating the tableware, fruits and vegetables stored inside. In addition, since the total width of the center beam is equal to the sum of the width of the two tank welding surfaces (about 20mm) and the sealing width of the door end face (about 15mm), the width of the center beam occupies a part of the left and right width of the functional tank, which limits the volume of the functional tank. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a washing machine which can prevent water from accumulating on the upper surface of the door body and prevent the accumulated water from entering the dishwasher in view of the current status of the prior art.

[0012] Preferably, the water guide surface is provided with a plurality of convex ribs extending in the left-right direction and arranged at intervals. When the door body is used as a drain board, the convex rib structure can prevent the placed objects from sliding.

[0013] Preferably, in the front-to-back direction, the water guide surface is formed in the main area in the middle of the upper surface of the door body, and the front edge and the rear edge of the upper surface of the door body are higher than the water guide surface. With such a structure, the accumulated water on the upper surface of the door body can only flow into the first water tank, and will not enter the gap between the door body and the sink tank from the front and rear edges and then invade the washing chamber.

[0014] Preferably, the rear edge of the door body is rotatably connected to the sink groove at the rear side of the second water tank, and the door body is provided with a switch assembly arranged near its rear edge, and the switch assembly is higher than the water guide surface and located behind the water guide surface. The switch assembly of the cleaning machine is placed at the rear of the door body to avoid false triggering. The above structure is adopted to prevent the accumulated water in the water guide surface from damaging the switch assembly.

[0015] Preferably, a decorative piece is provided in the sink groove at the rear side of the first sink, and the upper surface of the decorative piece is substantially aligned with the upper surface of the switch assembly. A mounting hole for the faucet pipe to pass through is provided on the sink groove and the decorative piece at the rear side of the first sink. The above structure makes the entire sink structure more beautiful.

[0016] Preferably, in the closed state, the edge of the door body sealed with the middle beam is aligned with the edge of the top opening of the first water tank or extends into the top opening of the first water tank. Such a structure is adopted to ensure that the accumulated water on the upper surface of the door body can be guided into the first water tank without back-seeping into the dishwasher.

[0017] Compared with the prior art, the advantages of the present invention are: on the basis of adopting the flip-up door body of the washing machine, the present invention makes the sunken platform troughs of the first water tank and the second water tank into a through-integrated structure; when the door body is closed, the edge of the door body can be directly sealed with the middle beam between the first water tank and the second water tank, and the total width of the middle beam can be reduced by 15 to 20 mm compared with the prior art, thereby saving left and right space, which is convenient for expanding the functional tank or water tank volume; the accumulated water on the upper surface of the door body can be directly wiped into the first water tank, avoiding the accumulated water from entering the dishwasher through the gap, which is beneficial to maintaining the cleanliness of the dishwasher.
