[0023] The utility model will be further described in detail in connection with the drawings. These drawings are all simplified schematic diagrams, and only schematically show the basic structure of the utility model, so they only show the components related to the utility model.

[0024] Embodiment 1

[0025] As Figures 1-4 shown in the specific embodiment of the high-temperature spraying device of the dishwasher of the utility model, Figure 3 As shown in the dishwasher of the utility model, it comprises a main washing sink 14 and a plurality of high-temperature spraying devices installed on the side wall of the main washing sink 14. In this embodiment, two high-temperature spraying devices are symmetrically arranged on the left and right side walls of the main washing sink 14.

[0026] Referring to Figures 1-4 , the high-temperature spraying device comprises a hollow pipe 1, a water flow cavity 2 arranged in the hollow pipe 1, and a water spraying nozzle 5 in communication with the water flow cavity 2. The cavity between the outer side of the water flow cavity 2 and the hollow pipe 1 forms a high-temperature air cavity 3 parallel to the extension direction of the water flow cavity 2. A through hole 4 is arranged on the side wall surface of the hollow pipe 1, the water spraying nozzle 5 passes through the high-temperature air cavity 3 transversely and then passes out of the through hole 4, and a gap 6 for high-temperature air spraying is formed between the through hole 4 and the water spraying nozzle 5. In this embodiment, the hollow pipe 1 is a square tube, and the water flow cavity 2 is a square tube arranged in the hollow pipe 1.

[0027] The two ends of the water flow cavity 2 are sealed by a first plug 7, and the two ends of the high-temperature air cavity 3 are sealed by a second plug 8.

[0028] The water spraying nozzle 5 and the through hole 4 are one-to-one corresponding, and the water spraying nozzle 5 sprays water towards the inside of the main washing sink 14.

[0029] The water flow cavity 2 is in communication with a water pump 9 through a water pipe 13, and the water pump 9 is communicated to a water tank (not shown). The oven 11 can be arranged in the water tank, so that the water in the water tank can be heated while the air is heated.

[0030] Referring to Figure 3 , the high-temperature air cavity 3 is communicated to the oven 11 through an air pipe 12, and the oven 11 is communicated to the air pump 10 through the air pipe 12.

[0031] The specific working principle of the utility model is as follows:

[0032] The water in the water tank is heated by the heating pipe, and is pumped into the water flow cavity 2 by the water pump 9, and the high-temperature air in the oven 11 is pumped into the high-temperature air cavity 3 which is separated from the water flow cavity 2 by only one metal plate by the air pump 10, the temperature of the air in the high-temperature air cavity 3 can be higher than 100℃, and the heating temperature of the water will not be higher than 100℃. The hot water is heated in the water pipe 13 by the temperature compensation of the high-temperature air, and the water in the water flow cavity 2 is further heated before being sprayed by the nozzle, and at the same time, the high-temperature air is blown to the water flow at the moment when the water flow is sprayed from the water spraying nozzle 5, so that the water flow is further heated and the direction of the water flow is changed, and the spraying angle of the water flow is enlarged. Under the impact of the high-temperature and high-pressure water flow, it is easier to remove the oil stains on the tableware. At the same time, the high-temperature air is blown into the water, and the oil stains are further removed by the principle of bubbling.

[0033] Embodiment 2

[0034] Reference Figure 5 , the difference from the embodiment 1 is that the water spraying end of the water spraying nozzle 5 is a tapered surface with a small front and a large back.

[0035] The tapered surface guides the high-temperature air to the center of the water spraying, and the high-temperature air is blown to the water flow, so that the spraying angle of the water spraying is further increased.

[0036] It should be understood that the specific embodiments described above are only used to explain the present application, and are not used to limit the present application. The obvious changes or modifications derived from the spirit of the present application are still within the protection scope of the present application.
