[0047] Figure 1 This is a cross-sectional diagram of the dishwasher operation: The sink has a bottom spray head that passes through the bottom of the sink and connects to an external pipe; the connection hole is sealed by welding. A small sunken water tank is also connected to the bottom of the sink for use during dishwasher operation. Figure 7 As shown: The sunken sink has a filter plate at the inlet, below which is an inner filter plate. A sand settling plate is located approximately 1 cm above the bottom plate, below the overflow outlet. The inner filter plate serves two purposes: first, it provides dual filtration; second, it prevents residual food from flowing into the water pump when rinsing and cleaning the filter plate after washing dishes. The sand settling plate at the bottom intercepts fine sand particles that pass through the filter plate during washing, preventing them from entering the water pump and causing wear. The upper spray head is integrated into the cover plate, which houses various pipes and electrical mechanisms, connecting to the opening and closing device. An inner sealing plate prevents moisture from entering, and reinforcing ribs are added to accommodate the cover plate's load-bearing capacity. The cover plate is hinged to the sink, and the outer pipes connect to the inner pipes of the cover plate via an adapter. Holes are provided at the adapter and hinge points for venting and allowing water to overflow from the sink. An arc-shaped side sealing plate connects to the inner sealing plate, sealing the gap between the cover plate and the sink when the cover is closed, preventing water from splashing out during washing dishes.
[0048] Figure 2 This is a schematic diagram of the piping with the cover open. The lower half of the piping is on the outside of the pool, while the upper half connects to the inside of the cover via an adapter. Figures 1 and 2 are schematic diagrams of the cover section alone. Figure 5 This is a schematic diagram of the junction between internal and external pipelines.
[0049] Figure 6 This is a diagram showing the location of the sink and dishwasher in the kitchen. Figure 6 The sink has a narrow overflow channel on the outer side against the wall. There are holes at the hinge and adapter of the cover. When the cover is open and used as a regular sink, any water overflowing from the sink will overflow through the overflow channel. When used as a dishwasher, the inner cover has an arc-shaped side cover on the overflow side. When the cover is closed, it can block the holes at the hinge and adapter of the cover, preventing the washing water from spraying out of the dishwasher.
[0050] Figure 8 , Figure 9 These are schematic diagrams of the opening and closing device in both the closed and open states of the cover. The sprocket of the opening and closing system is fixed to the inner wall by a triangular bracket. The sprocket is supported on the corner of the triangular bracket via bearings, and the chain changes direction via the sprocket. One end of the chain is connected to the cover plate, and the lower end is connected to a rack. The lower end of the rack is connected to a counterweight to balance the weight of the cover plate. The drive mechanism consists of a geared motor and a worm gear. The motor drives the worm gear to pull the rack downwards or push it upwards, thus opening or closing the cover plate. Figure 11 The diagram shows the construction of a chain unit. Each unit has an outwardly extending limiting tongue on the right side to ensure that the chain, after being turned by the sprocket, forms a straight line that pushes or pulls the cover plate to rotate.
[0051] Figure 11 This is a schematic diagram showing the relationship between the circulating water pump, water distribution valve, connecting pipe, and outlet pipe of the submerged water tank. Figure 12 This is a schematic diagram of the water distribution valve. When the iron core coil is energized, it generates a magnetic field that pushes the magnet on the push rod downwards, closing the valve and preventing water from flowing through that path. When the power is off, the spring pulls the push rod back to its original position, opening the valve. Water from the circulating pump then flows through this path and is sprayed out through the shower head to rinse the dishes. A plan view of the multi-way water distribution valve is shown below. Figure 13 As shown
[0052] When in use, open the lid, place the dish rack into the sink, put the bowls, plates and other tableware to be washed in the corresponding positions on the rack, close the lid, turn on the tap water head, add an appropriate amount of water and detergent, etc., turn on the electric heating element to heat the washing water (the start and stop temperature can be set), start the circulating water pump, and turn the electric water distribution valve to turn the valve in time to connect the corresponding pipeline system in sequence. The spray heads at different positions spray hot water in sequence to wash the tableware from different directions.
[0053] Used as a washing sink: When the dishes are removed from the basket and the lid is half-open, the shower head and circulating water pump system will automatically lock, while the tap water nozzles can be turned on and off, allowing it to be used as a regular sink.
[0054] When not in use, with the cover closed, the surface can bear some weight and can be used for purposes such as food preparation; the folded-down faucet on top of the cover can be raised to fill kettles, etc. Figure 5 As shown (without needing to open the cover), the kitchen is also quite neat and tidy.
[0055] The cover assembly of this utility model adopts an integrated structure, which can integrate various functional components. If it is necessary to add functional components, simply replace the cover assembly to add functional components, thereby realizing the upgrade of the entire dishwasher and saving costs.
