Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of dishwashers, and in particular relates to a high-temperature cleaning energy-saving dishwasher. Background Art
[0002] Dishwashers require high-temperature hot water when washing or rinsing dishes, and require a water flow with a strong jet force and a wide jet range to rinse the dishes and enhance the washing effect. Traditional dishwashers transport hot water from a heating water tank to a water nozzle through a water pipe. Heat loss occurs during the transportation process through the water pipe, which reduces the water outlet temperature of the nozzle. On the other hand, in traditional water heating systems, the heating speed of the heating pipe is limited, and it is difficult to obtain high-temperature hot water in a short time.
[0003] In order to enhance the cleaning effect, some dishwashers currently have jet holes that spray air into the main wash tank, using the bubbling principle to accelerate the removal of oil stains on tableware. There will be many water nozzles and jet holes on the side wall of the main wash tank, which increases the processing requirements for the main wash tank. Summary of the invention
[0004] The purpose of the present invention is to overcome the defects in the prior art of heat loss in the hot water transportation process and insufficient main wash water temperature, and to provide a high-temperature cleaning energy-saving dishwasher that can ensure high-temperature water spraying from a water nozzle.
[0005] The technical solution adopted by the present invention to solve its technical problem is: A high-temperature cleaning energy-saving dishwasher comprises a main wash water tank and a plurality of high-temperature water spray mechanisms arranged on the side wall of the main wash water tank, wherein the high-temperature water spray mechanisms comprise: a hollow tube, a water flow cavity arranged in the hollow tube, and a water spray nozzle connected to the water flow cavity; a high-temperature air cavity parallel to the extension direction of the water flow cavity is formed by the cavity between the outer side of the water flow cavity and the hollow tube; a through hole is arranged on the side wall surface of the hollow tube, the water spray nozzle passes through the high-temperature air cavity horizontally and then passes out from the through hole, and an air gap for high-temperature air to be sprayed is formed between the through hole and the water spray nozzle.
[0006] Furthermore, the high-temperature air cavity is connected to the oven through a first air pipe, and the oven is connected to the air pump through a second air pipe; the first air pipe includes an arched high pipe, and the top of the arched high pipe is higher than the top of the main washing water tank.
[0007] Furthermore, the hollow tube is a square tube, and the water flow cavity is a square tube inserted into the hollow tube.
[0008] Furthermore, a heat recovery air cavity connected thereto is provided at the upper portion of the main wash water tank, the bottom of the heat recovery air cavity is connected to the main wash water tank through a first air hole, and the top of the heat recovery air cavity has a second air hole.
[0009] Furthermore, the heat recovery air cavity is connected to the air inlet of the air pump through a third air pipe.
[0010] Furthermore, both ends of the water flow cavity are sealed by a first plug, and both ends of the high-temperature air cavity are sealed by a second plug.
[0011] Furthermore, there are a plurality of water spray nozzles corresponding to the through holes in a one-to-one manner, and the water spray nozzles spray water toward the inside of the main wash tank.
[0012] Furthermore, the water flow cavity is connected to a water pump through a water pipe, and the water pump is connected to a water tank; the oven is arranged inside the water tank.
[0013] Furthermore, the upper portion of the main wash water tank is sealed by a cover plate, and the first air hole is located below the cover plate.
[0014] Furthermore, a plurality of ultrasonic transducers are arranged on the main wash water tank.
[0015] The beneficial effects of the high-temperature cleaning energy-saving dishwasher of the present invention are: 1. By arranging the water flow cavity and the high-temperature air cavity side by side, the water in the water flow cavity is further heated by the high-temperature air cavity to ensure the temperature of the water flow sprayed from the water nozzle. At the same time, the water nozzle is passed through the through hole, and the air gap between the through hole and the water nozzle is used to form an air jet hole. The water nozzle and the air jet hole are combined together, which reduces the processing technology of the main washing sink; and the high-temperature gas is blown directly to the water nozzle to further heat the hot water sprayed from the water nozzle, and the airflow changes the direction of the water flow, increasing the spray angle of the nozzle water. It can absorb and rinse the oil stains on the tableware more quickly.
[0016] 2. By setting the top of the arched pipe higher than the top of the main wash water tank, it is prevented that the water in the main wash water tank flows back into the air pump after the air pump stops blowing, thereby affecting the service life of the air pump.

DETAILED DESCRIPTION
[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0020] Example 1
[0021] like Figure 1-Figure 5 A specific embodiment of a high-temperature cleaning energy-saving dishwasher of the present invention is shown, comprising a main wash water tank 14 and a plurality of high-temperature water spray mechanisms arranged on the side wall of the main wash water tank 14, the high-temperature water spray mechanism comprising: a hollow tube 1, a water flow cavity 2 arranged in the hollow tube 1 and a water spray nozzle 5 connected to the water flow cavity 2; a high-temperature air cavity 3 parallel to the extension direction of the water flow cavity 2 is formed between the outer side of the water flow cavity 2 and the cavity between the hollow tube 1; a through hole 4 is arranged on the side wall surface of the hollow tube 1, the water spray nozzle 5 passes through the high-temperature air cavity 3 horizontally and then passes through the through hole 4, and an air gap 6 for high-temperature air to be sprayed is formed between the through hole 4 and the water spray nozzle 5.
[0022] In this embodiment, two high-temperature water spraying mechanisms are respectively installed on the left and right side walls of the main washing water tank 14 and are arranged parallel to each other. The water spraying nozzle 5 penetrates into the main washing water tank 14 to spray water on the dishes.
[0023] See also Figure 2 The high-temperature air cavity 3 is connected to the oven 11 through the first air pipe 12, and the oven 11 is connected to the air pump 10 through the second air pipe 15; the first air pipe 12 includes an arched high pipe 121, and the top of the arched high pipe 121 is higher than the top of the main washing water tank 14, ensuring that the arched top of the arched high pipe 121 is higher than the water surface in the main washing water tank 14, preventing the water in the main washing water tank 14 from flowing back into the air pump 10 after the air pump stops blowing, thereby affecting the service life of the air pump 14.
[0024] See also Figure 3-Figure 5The hollow tube 1 is preferably a square tube, and the water flow cavity 2 is a square tube inserted in the hollow tube 1. In this way, there is only one piece of metal between the water flow cavity 2 and the high-temperature air cavity 3 for heat conduction, which can better conduct the heat of the high-temperature air with a temperature higher than 100°C to the hot water in the water flow cavity 2 with a temperature lower than 100°C and already heat-damaged.
[0025] See also Figure 1 A heat recovery air cavity 16 connected to the main wash water tank 14 is provided at the upper part thereof, the bottom of the heat recovery air cavity 16 is connected to the main wash water tank 14 via a first air hole 17, and a second air hole 18 is provided at the top of the heat recovery air cavity 16. The hot air in the main wash water tank 14 is recovered via the first air hole 17, and at the same time, the air pump 10 inhales air from the atmosphere via the second air hole 18.
[0026] The heat recovery air chamber 16 is connected to the air inlet of the air pump 10 through the third air pipe 19 .
[0027] See also Figure 3 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] There are a plurality of water spray nozzles 5 corresponding to the through holes 4 in a one-to-one manner, and the water spray nozzles 5 spray water toward the inside of the main washing water tank 14 .
[0029] The water flow cavity 2 is connected to the water pump 9 through the water pipe 13, and the water pump 9 is connected to the water tank 22; the oven 11 is arranged inside the water tank 22. The oven 11 heats the water in the water tank 22 while heating the air.
[0030] The upper portion of the main wash water tank 14 is sealed by a cover plate (not shown), and the first air hole 17 is located below the cover plate.
[0031] In order to enhance the cleaning effect, a plurality of ultrasonic transducers 21 are provided on the main washing tank 14 .
[0032] The specific working principle of the present invention is: The water in the water tank 22 is heated by the heating pipe, and the water is pumped into the water flow cavity 2 by the water pump 9. At the same time, the high-temperature air heated in the oven 11 is pumped into the high-temperature air cavity 3 separated from the water flow cavity 2 by only a metal plate by the air pump 10. The air temperature in the high-temperature air cavity 3 can be higher than 100°C, while the heating temperature of the water will not be higher than 100°C. The heat loss of hot water during transportation in the water pipe 13 is compensated by the temperature of the high-temperature air, and the water in the water flow cavity 2 is further heated before the nozzle is sprayed out; at the same time, at the moment when the water flow is sprayed out from the water nozzle 5, the high-temperature air blows to the water flow to further heat the water flow, change the direction of the water flow, and expand the spray angle of the water flow. Under the impact of 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 bubbling principle is used to further enhance the removal of oil stains.
[0033] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
