Description

Technical Field

[0001] This utility model relates to the field of dishwashers, and in particular to a dual-effect energy-saving dishwasher. 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] Dishwashers primarily remove stains from dishes by rinsing with hot water. This process generates a large amount of hot wastewater and steam, leading to heat loss and affecting the ambient temperature. Furthermore, the dishwasher requires heating cold water directly to the necessary washing temperature, resulting in high overall power consumption. Therefore, further improvements to the existing dishwasher structure are necessary. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-effect energy-saving dishwasher includes a frame, a conveying device, a main wash water tank, a first spray head, a wastewater tank, a high-temperature water tank, a second spray head, a first coil, and an air-heating system. The frame has a mounting cavity with openings at both ends and a condensing cavity; the condensing cavity is located above and communicates with the mounting cavity. The conveying device is mounted on the frame and located within the mounting cavity, with both ends extending outwards from the openings at both ends of the mounting cavity. The main wash water tank is mounted on the frame. The first spray head is located within the mounting cavity and directly above the conveying device. The shower head is connected to the main wash water tank; the wastewater tank is mounted on the frame and connected to the main wash water tank; the high-temperature water tank is mounted on the frame; the second shower head is mounted in the mounting cavity and located directly above the conveying device, and the second shower head is connected to the high-temperature water tank; the first coil is mounted in the wastewater tank, and the input end of the first coil extends out of the wastewater tank to form a water inlet; the air heat energy system is mounted in the condensation cavity, and the input end of the air heat energy system is connected to the output end of the first coil, and the output end of the air heat energy system is connected to the input end of the high-temperature water tank.

[0007] As a preferred embodiment, the conveying device includes a conveyor frame, a conveyor belt, a drive mechanism, and a material rack; the conveyor frame is mounted on a machine frame; the conveyor belt is mounted on the conveyor frame and drives the conveyor belt to move back and forth; the material rack is mounted on the conveyor belt and driven by the conveyor belt, and the material rack consists of multiple racks arranged at intervals along the conveying direction of the conveyor belt.

[0008] As a preferred option, the frame is provided with a flow guide shroud that connects the mounting cavity and the condensation cavity, and the flow guide shroud is located outside the opening end of the mounting cavity.

[0009] As a preferred option, two air deflectors are provided, with each air deflector located on the outer side of the two openings of the mounting cavity. Each air deflector is equipped with a second coil, and the output end of the first coil is connected to the two second coils, and is connected to the input end of the air thermal energy system through the two second coils.

[0010] As a preferred option, a filter screen is installed at the lower end of each fairing.
