Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a dishwasher with wastewater utilization function. Background Technology

[0002] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Fully automatic dishwashers on the market can be divided into two categories: household and commercial. Household fully automatic dishwashers are only suitable for home use and mainly include cabinet-style, countertop-style, sink-integrated, and combined models. Commercial dishwashers can be classified into five main categories according to their structure: cabinet-style, hood-style, basket-type, belt-type, and ultrasonic. They reduce the labor intensity of kitchen staff in restaurants, hotels, and government canteens, improve work efficiency, and enhance hygiene.

[0003] Some dishwashers require soaking dishes in hot water for a period of time before rinsing to achieve better washing results. However, this requires an additional heating element to continuously heat the water in the soaking tank, leading to higher overall power consumption for the dishwasher. Furthermore, dishwashers generate a large amount of hot wastewater after washing, which current models simply discharge directly, wasting both energy and water. Therefore, further improvements to the existing dishwasher design are necessary. Utility Model Content

[0039] Please refer to Figures 1 to 2 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including a frame 10, a conveying device 20, an immersion tank 30, a main washing water tank 40, a first spray head 50, a wastewater tank 60, a high-temperature water tank 70, and a second spray head 80.

[0040] The frame 10 has a mounting cavity 101 with openings at both ends. In this embodiment, a condensation cavity 102 communicating with the mounting cavity 101 is provided inside the frame 10. The water vapor generated after the high-temperature rinsing all enters the condensation cavity 102 upwards. The upper end of the condensation cavity 102 has an opening communicating with the outside. A controller 12 is provided on the frame 10. The conveying device 20, soaking tank 30, main washing water tank 40, first spray head 50, wastewater tank 60, high-temperature water tank 70, and second spray head 80 are all connected to the controller 12.

[0041] The conveying device 20 is mounted on the frame 10 and located in the mounting cavity 101, with both ends of the conveying device 20 extending outward from the openings at both ends of the mounting cavity 101. In this embodiment, the conveying device 20 includes a conveying frame 21, a conveyor belt 22, a first drive mechanism 23, and a material rack 24. The conveying frame 21 is mounted on the frame 10. The conveyor belt 22 is mounted on the conveying frame 21 and can be driven back and forth. The first drive mechanism 23 is mounted on the frame 10 and drives the conveyor belt 22 to move back and forth. The material rack 24 is mounted on the conveyor belt 22 and is driven back and forth by the conveyor belt 22. The material rack 24 consists of multiple racks arranged at intervals along the transmission direction of the conveyor belt 22, and the material rack 24 is used to limit the position of the tableware.

[0042] The soaking tank 30 is located on the side of the frame 10 and on the side of the input end of the conveying device 20. The tableware to be cleaned is first soaked in the soaking tank 30 and then placed into the conveying device 20 to complete the cleaning process.

[0043] The main washing water tank 40 is mounted on the frame 10. In this embodiment, the main washing water tank 40 and the wastewater tank 60 are connected by a pipe 41. The pipe 41 is located at the upper end of the main washing water tank 40 to prevent residual residue in the recovered washing water from the main washing water tank 40 from entering the wastewater tank 60, thereby preventing residue from entering the soaking pool 30 through the wastewater tank 60. A filter screen 42 is installed at the opening of the pipe 41 facing the main washing water tank 40 to further prevent residue from entering the wastewater tank 60. A drain port 43 connecting the interior of the main washing water tank 40 is provided at the lower end of the main washing water tank 40.

[0044] The first spray head 50 is mounted on the frame 10 and located directly above the conveying device 20. The first spray head 50 is connected to the main washing water tank 40. In this embodiment, there are two first spray heads 50 arranged vertically, with the two first spray heads 50 located on the upper and lower sides of the conveying device 20, respectively, so as to realize the rinsing process of tableware from both upper and lower directions.

[0045] The wastewater tank 60 is mounted on the frame 10 and located next to the main wash tank 40. The input end of the wastewater tank 60 is connected to the main wash tank 40, and the output end of the wastewater tank 60 is connected to the input end of the soaking tank 30. The wastewater in the wastewater tank 60 completes the soaking process of the tableware before rinsing, which not only avoids the waste of heat energy in the wastewater, but also avoids the waste of water resources. At the same time, it can also remove the heating device in the soaking tank 30, effectively reducing the overall power of the dishwasher. The wastewater tank 60 is equipped with a filter tube 61, which extends vertically. The upper end of the filter tube 61 has an overflow port 62, and the lower end of the filter tube 61 extends outward from the wastewater tank 60. The overflow port 62 filters out the stains floating on the top of the wastewater and excess wastewater, preventing the stains in the wastewater from affecting the soaking effect of the tableware.

[0046] In this embodiment, a first coil 63 is installed inside the wastewater tank 60. The input end of the first coil 63 is provided with a water inlet 64 communicating with the outside. The output end of the first coil 63 extends outward from the wastewater tank 60 and communicates with the high-temperature water tank 70, so that the cold water entering from the outside is preheated by contacting the high-temperature wastewater through the first coil 63, and the temperature of the wastewater is reduced to between 45-55°C before entering the soaking pool 30. A second coil 11 is installed inside the condensation chamber 102. The output end of the first coil 63 is connected to the second coil 11, and is connected to the high-temperature water tank 70 through the second coil 11, so that the water in the condensation chamber 102 comes into contact with the high-temperature steam through the second coil 11, thereby further heating the water in the second coil 11 before entering the high-temperature water tank 70. The high-temperature water tank 70 heats the preheated water to above 82-90°C in a short time, thereby completing the high-temperature rinsing process of the tableware. The output end of the wastewater tank 60 is connected to the input end of the soaking tank 30 through an induction pump 65. The induction pump 65 works in conjunction with a water level sensor (not shown in the figure) installed inside the wastewater tank 60. The induction pump 65 only starts working when the wastewater in the wastewater tank 60 reaches a certain height, so as to avoid sucking the dirt on the upper layer of wastewater into the soaking tank 30 when the water level is insufficient.

[0047] The high-temperature water tank 70 is mounted on the frame 10. In this embodiment, a heating element 71 is installed inside the high-temperature water tank 70 to heat the preheated water inside the high-temperature water tank 70 to the required temperature. The outer wall of the high-temperature water tank 70 is covered with insulation cotton 72 to prevent the temperature inside the high-temperature water tank 70 from escaping. A high-temperature water pump 73 is installed outside the high-temperature water tank 70.

[0048] The second spray head 80 is mounted on the frame 10 and located directly above the conveying device 20. The second spray head 80 is connected to the high-temperature water tank 70. In this embodiment, two second spray heads 80 are arranged vertically, one above the other, located on the upper and lower sides of the conveying device 20 respectively, allowing for simultaneous rinsing of the tableware from both vertical and horizontal directions, thus ensuring rinsing quality. In this embodiment, the second spray head 80 is connected to the high-temperature water tank 70 via a high-temperature water pump 73.

[0049] Furthermore, a drying device 90 is also included, comprising a second drive mechanism 91, a heating chamber 92, an air supply assembly 93, and an air outlet assembly 94. The second drive mechanism 91 is mounted on the frame 10; the heating chamber 92 is mounted on the frame 10 and located beside the output end of the second drive mechanism 91; the air supply assembly 93 is located between the second drive mechanism 91 and the heating chamber 92, and has a fan blade 931 inside, which is connected to the output end of the second drive mechanism 91 and driven by the second drive mechanism 91 to rotate back and forth; the air outlet assembly 94 is connected to the air supply assembly 93 and located beside the conveying device 20, and has an air outlet 941 facing the conveying device 20. The high-temperature gas generated by the heating chamber 92 is sent into the air outlet assembly 94 through the air supply assembly 93, and blown through the air outlet 941 onto the washed tableware in the conveying device 20, thereby drying the tableware.

[0050] The key design feature of this invention is that the wastewater tank's input end is connected to the main washing tank, and the wastewater tank's output end is connected to the soaking tank's input end. This allows the high-temperature wastewater recovered from the main washing tank to enter the soaking tank, thus achieving a high-temperature soaking process for the tableware. No additional heating device is needed, effectively reducing overall power consumption. Simultaneously, it avoids wasting heat energy in the high-temperature wastewater, and the wastewater recycling effectively saves water resources. Furthermore, a filter pipe is installed in the wastewater tank, extending vertically. The upper end of the filter pipe has an overflow outlet, and the lower end extends outward from the wastewater tank. This allows dirt and excess wastewater on the surface of the wastewater in the tank to be discharged through the overflow outlet, preventing dirt in the wastewater tank from affecting the soaking effect.

[0051] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
