[0017] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0018] See Figures 1 to 3 This utility model discloses a sink-type dishwashing device, including a sink body 1. The sink body 1 is divided into a dishwashing area and a rinsing area. The dishwashing area is used to place the dishes to be washed, while the rinsing area is used for daily rinsing. A water-blocking strip 3 is provided between the dishwashing area and the rinsing area to effectively prevent water from the rinsing area from flowing into the dishwashing area, ensuring the orderly progress of the washing process. It can also recycle the hot water used for washing dishes. A partition 2 is provided in the middle of the dishwashing area. The bottom of the partition 2 is separated from the bottom of the sink body 1. The left side of the partition 2 is used for washing dishes, and the right side is used for washing pots and pans. The gap at the bottom of the partition 2 facilitates the flow of water to the heating box 5 during dishwashing, which helps the circulation and distribution of water and improves the washing effect.
[0019] A support frame is installed inside the dishwashing area of the sink body 1. The support frame includes a bottom tube 201 that runs along the width of the sink body 1. An upward-facing branch tube 202 is provided on the side of the bottom tube 201. Both the bottom tube 201 and the branch tube 202 have hollow interiors. The upper part of the branch tube 202 has a bend. When in use, the tableware is placed on the upper part of the branch tube 202, so that the nozzle of the branch tube 202 can produce a rinsing effect on the interior, allowing the water to spray out at a suitable angle for better cleaning. The bottom of the branch tube 202 is rotatably connected to the bottom tube 201. When in use, the branch tube 202 can be flexibly rotated as needed to adjust the water flow direction to meet the cleaning needs of tableware of different shapes and arrangements.
[0020] To achieve rational water resource utilization and efficient cleaning, a comprehensive water circulation system is installed. A return water hole 303 is located at the bottom of the dishwashing area, below which is a heating tank 5. The outlet of the heating tank 5 is connected to a bottom pipe 201, and a water pump is installed on this connecting pipe. The pump draws heated water from the heating tank 5 into the bottom pipe 201, and then sprays it out through a branch pipe 202 to clean the dishes. The heating tank 5 contains a heating plate, and a water inlet is located on its side, connected to a water heater. This ensures that hot water is added to the heating tank 5, reducing heating time. A drain outlet is located at the bottom of the heating tank 5, connected to a drain pipe at the bottom of the rinsing area, and a drain pump is installed at the drain outlet. During the cleaning process, dirt and impurities on the dishes enter the return water hole 303 with the water flow. After being filtered by the filter screen, larger impurities are intercepted on the screen, preventing them from entering the heating tank 5 and affecting the normal operation of the equipment. Smaller impurities and wastewater enter the heating tank 5. After a period of cleaning, the wastewater and impurities in the heating tank 5 are discharged into the drain pipe by a sewage pump, ensuring the cleanliness of the water in the heating tank 5. A drain hole 101 is provided at the bottom of the rinsing area, and a drain pipe is provided at the bottom of the drain hole 101 for discharging the wastewater after rinsing.
[0021] To further improve the cleaning effect, some auxiliary cleaning components are also provided. A universal tube 301 is installed on the side of the water tank body 1 in the middle area, and a cleaning head 302 that sprays water upward is installed at the end of the universal tube 301. When it is necessary to clean some larger pots and pans, the angle of the universal tube 301 can be adjusted so that the cleaning head 302 is aimed at the part that needs to be cleaned, and targeted rinsing can be performed to enhance the flexibility and comprehensiveness of the cleaning.
[0022] In addition, the upper part of the bracket is provided with an end cap 4, the side of which is hinged to the sink body 1 for easy opening and closing. The inner side of the end cap 4 is provided with a rotating nozzle. During the washing process, the rotating nozzle can rotate 360 degrees to spray water, rinsing the tableware placed on the bracket in all directions, ensuring that every corner of the tableware is cleaned, which greatly improves the cleanliness of the cleaning.
[0023] When using this sink dishwasher, first place the dishes to be washed on the rack, close the end cap 4, and then start the water pump and heating tank 5. The heating tank 5 contains cleaning solution. After the heating tank 5 heats the water to a suitable temperature, the water pump draws the hot water into the bottom pipe 201 and branch pipe 202. The water is then sprayed out through the branch pipe 202 and the rotating nozzle on the inner side of the end cap 4 to clean the dishes. Multiple spray pipes or rotating nozzles can also be installed around the inner wall and on the back of the top cover to spray water to clean the dishes. The wastewater generated during the process enters the heating tank 5 through the return water hole 303. After being filtered by the filter screen, the clean water continues to be recycled, while impurities and wastewater are periodically discharged by the drain pump. The water pump delivers high-pressure water directly to the inside of the bowl through branch pipe 202, greatly reducing washing time. The universal pipe 301 also allows for direct cleaning of cookware. The design of the sink body 1 increases the capacity for cookware, ensuring effective cleaning. By directly cleaning with high-pressure water, the dishwashing device is integrated into the sink, making full use of existing kitchen space without requiring additional dedicated space. It offers efficient and convenient dishwashing functions and can meet the cleaning needs of different items such as cookware.
