As shown in fig. 1 and 2, the present embodiment provides a tankless heater including a housing 1, a spiral tube 3, a cyclone 4, a burner 5, and an igniter assembly 6.

A heating chamber 2 is arranged in the shell 1, and the spiral pipe 3, the cyclone 4 and the burner 5 are all positioned in the heating chamber 2. The spiral pipe 3 is a pipeline for passing the clean water, and is arranged to be spiral so as to prolong the time of the clean water in the shell 1 and ensure that the clean water can be heated. The spiral pipe 3 is provided with a water inlet 3a and a water outlet 3b. The water inlet 3a and the water outlet 3b both penetrate through the bottom of the shell 1. The water inlet 3a and the water outlet 3b are both downward, so that the water in the spiral pipe 3 is completely emptied when the spiral pipe is not used.

A passage 8 for passing air is provided in the housing 1. Specifically, the shell 1 has two layers, and the space between the two layers of shells is the channel 8. The lower part of the shell 1 is connected with an air inlet 14, and the air inlet 14 is communicated with the channel 8. In use, the air inlet 14 is connected to a fan which provides air from the inlet passage 8 which in turn provides air for combustion. Since the air flows through the passage 8 from bottom to top, the air is preheated by the heat in the heating chamber 2, so as to prevent the air temperature from being low and affecting the efficiency of the combustion reaction.

Referring to fig. 3, the cyclone 4 is located above the burner 5. The cyclone 4 comprises a cone 41 and a cyclone plate 42. The passageway 8 communicates with the top of the cyclone 4 to provide an air flow. The conical barrel 41 is in the shape of an inverted cone, i.e., an inverted conical barrel body. To cause the airflow to swirl in a helical fashion. The channel 8 communicates with the top of the conical barrel 41, and the conical barrel 41 communicates with the combustion chamber 7 (the combustion chamber 7 is described below). The cyclone plate 42 is annular and is sleeved on the bottom of the conical barrel 41, and the cyclone plate 42 is located in the combustion chamber 7 (the combustion chamber 7 is described below). A plurality of ventilation holes 9 are distributed on the circumference of the cyclone plate 42, the channel 8 is communicated with the top of the combustion chamber 7, and another air flow is provided, passes through the ventilation holes 9 and is dispersed by the ventilation holes 9 to accelerate the mixing of the air and the oil mist. The cyclone plates 42 are circumferentially distributed with a plurality of cyclone pieces 10, and the cyclone pieces 10 extend from the bottom of the ventilation holes 9 in a downward inclined manner. The cyclone member 10 tilts the air to rotate the air flow passing through the vent hole 9, further mixing the air and the oil mist sufficiently.

The igniter assembly 6 includes an oil jet 61, an ignition electrode 62, and a pressure plate 63. The ends of the fuel injector 61 and the ignition electrode 62 are located within the cone 41. The fuel spray nozzle 61 sprays fuel into mist so as to be fully mixed with gas, and the combustion efficiency is improved. The ignition electrode 62 is used to ignite the oil mist. The fuel injector 61 and the ignition electrode 62 are both mounted on a pressure plate 63, and the pressure plate 63 is fixed to the top of the housing 1. When the fuel injection device is used, the fuel injection nozzle 61 is connected with a fuel pump, and the fuel pump supplies fuel.

The burner 5 includes a burner outer cylinder 51, an outer cover 52, a heat collecting cover 53, and an upper cover 54. A vertically penetrating combustion chamber 7 is provided in the burner outer cylinder 51. An upper cover 54 is provided on the top of the burner outer barrel 51, and the upper cover 54 is used for connection with the casing 1.

The burner outer cylinder 51 is arranged in the outer cover 52, and a cavity 11 with an open top and a closed bottom is arranged between the burner outer cylinder 51 and the outer cover 52. The cavity 11 is communicated with the channel 8, and the outer burner cylinder 51 is provided with a plurality of through holes 12 for communicating the cavity 11 with the combustion chamber 7. The passage 8 introduces an air flow into the chamber 11 to ensure the mixing of the oil mist with the air.

The heat collecting cover 53 is arranged at the bottom of the outer combustor cylinder 51, the combustion chamber 7 is conical, the heat collecting cover 53 is inverted conical, and a window is arranged in the middle of the heat collecting cover 53. The flame burned in the burner 5 is ejected from the window in the middle of the heat collecting cover 53.

The shell 1 is provided with a chimney 13 which penetrates through the top of the shell 1, and the chimney 13 is communicated with the heating chamber 2.

An insulating pad 15 and firebricks 16 are installed at the bottom of the heating chamber 2, the firebricks 16 are positioned above the insulating pad 15, and the spiral pipe 3 is provided on the firebricks 16. Insulation is achieved by the insulation mat 15 and the refractory bricks 16.

As a further preferred aspect of the above technical solution, the spiral pipe 4 is divided into an outer ring and an inner ring, the burner 5 is disposed between the inner rings, and cold water enters the inner ring from the water inlet 3a, passes through the outer ring, and is then discharged from the water outlet 3b.

The working process of the instant heating type heater is as follows:

the fuel is pressurized by an oil pump connected with the fuel injection nozzle 61, atomized and sprayed out through the fuel injection nozzle 61, fully mixed with air, and ignited and combusted through the ignition electrode 62. The combustion reaction mainly takes place in the burner 5. Air is blown in from the bottom of the shell 1 by a fan, and enters the upper part of the shell 1 after being preheated by the channel 8. The first airflow enters from the top of the cyclone 4. The second air flow enters from the top of the burner 5 and forms a certain rotating air flow through the cyclone plate 42 to accelerate the mixing of the air and the oil mist. A third air flow enters between the chambers 11 and then enters the combustion chamber 7 through the perforations 12 in the outer burner cylinder 51 to ensure thorough mixing and combustion of the oil mist with the air and to spread out the flame to heat the coil 3. Water flow enters from a water inlet 3a of the spiral pipe 3 and is discharged from a water outlet 3b, and hot water is formed through heat exchange.
