Description

Technical Field

[0001] The utility model relates to the technical field of shower box group heating, in particular to a shower box group heater and an automatic control system thereof. Background Art

[0002] At present, the commonly used shower equipment uses solar energy, electric energy, etc. for heating, but they have limitations when used in the wild. Solar shower equipment is generally divided into two ways of use. One is to use a curved reflector to directly use solar radiation to heat the water body; the other is to use a solar power generation panel to convert solar radiation into electrical energy and then heat the water body. Solar shower equipment is greatly affected by weather factors. It is extremely inefficient when the solar radiation is low on cloudy days, and it cannot be used at night when there is no solar radiation. In order to ensure the heating efficiency, the reflective surface or solar conversion panel that collects solar radiation must have sufficient area, resulting in a large size of the equipment that is not conducive to transportation. Electric shower equipment has fast heating efficiency, but high energy consumption. It cannot be used independently when there is no mains connection in the field. In order to ensure its operation, it is necessary to add supporting high-power power generation equipment. It is inconvenient to use in the field. Electric shower equipment will cause leakage of the circuit due to aging and other factors during use, which will make the water body charged, which may cause the shower operator to be electrocuted.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In this embodiment, the smoke exhaust duct 6 is connected to the atmosphere, the port of the spray pipe 3 located outside the combustion chamber 1 is connected to the oil outlet of the pressure oil pump through the oil supply pipeline, and the water inlet 21 of the coil 2 is connected to the water outlet of the water pump through the water supply pipeline. After the water enters the coil 2, the oil in the oil supply pipeline enters the spray pipe 3 and is sprayed out in the form of oil mist. After mixing with the air coming in from the air collecting tube 4, the spark plug 5 ignites, and the mixed gas burns in the combustion chamber 1, providing heat for the water inside the coil 2, so that the water temperature in the coil 2 rises. During the whole process, the spray pipe 3 has a preheating effect on the fuel, so that the fuel spray effect is better, the fuel combustion is more complete, the heating efficiency is high, and the coil 2 has a large heat exchange area. In this embodiment, the smoke exhaust duct 6 can also be connected to the exhaust fan to control the air pressure in the combustion chamber 1.

[0031] Specifically, the top wall and the side wall of the combustion chamber 1 are double-layered, an air inlet 7 is provided at the lower portion of the outer side wall of the combustion chamber 1 , and the interlayer formed by the inner wall and the outer wall of the combustion chamber 1 is connected to the air collecting tube 4 .

[0032] In this embodiment, the air inlet 7 is connected to the fan, the top wall and the side wall of the combustion chamber 1 are set as a double layer, and the air inlet 7 is set at the lower part of the interlayer of the heating chamber side wall, so that the air rises in a spiral manner along the interlayer, passes through the air collecting tube 4, and mixes with the oil mist. The oil mist burns in the combustion chamber 1 to heat the coil 2. Since the air collecting tube 4 is at the upper end of the combustion chamber 1, the flame can be directed downward, and the high-temperature gas can ascend from the lower part of the combustion chamber 1, exchange heat with the coil 2, and then be discharged through the smoke exhaust duct 6, so that the heat utilization rate is high.

[0034] In this embodiment, the fuel is sprayed out as oil mist from the spray head 33 through the spray pipe 3, and the oil mist is mixed with the air coming in from the air collecting tube 4 and burned. The temperature of the spray pipe 3 is relatively high, which has a preheating effect on the flowing fuel, so that the spray effect of the spray head 33 is better and the fuel burns more completely. The spray heads 33 are arranged at intervals from top to bottom on the side wall of the spray pipe 3, so that there are multiple flames spaced from top to bottom in the combustion chamber to heat the coil 2, and the coil is heated evenly from top to bottom. Since the temperature of the outer flame of the flame is the highest, multiple flames are arranged in this embodiment, which makes full use of the outer flame of the flame and significantly improves the heating efficiency of the heater. A one-way valve 5 is arranged on the port of the spray pipe 3 outside the combustion chamber to make the fuel flow in one direction to prevent the hot fuel from flowing back and causing dangerous accidents.

[0035] Specifically, the coil 2 is double-layered, including an inner coil 23 and an outer coil 24. The inner coil 23 is integrally connected to the upper end of the outer coil 24. The lower end of the inner coil 23 is the water outlet 22, and the lower end of the outer coil 24 is the water inlet 21. The coil 2, the spray tube 3 and the air collecting tube 4 are coaxial.

[0036] In this embodiment, the coil 2 is arranged in two layers, which further increases the heat exchange area. The coil 2, the spray pipe 3 and the air collecting tube 4 are coaxial, which further makes the coil 2 heated evenly.

[0037] In the above embodiment, the coil 2 can also be arranged as three layers, which can increase the water capacity and meet the demand for hot water without affecting the heating efficiency.

During the heating process, the automatic control system monitors in real time whether the oil mist in the mixing chamber is ignited, the oil circuit solenoid valve, the water temperature in the coil, the smoke temperature in the exhaust duct, and the flow rate on the water supply pipeline.

[0040] Preferably, the controller is also electrically connected to a display screen, which displays the heater operating voltage, operating current and accumulated working time, so that the working status of the heating can be monitored intuitively in real time to further avoid safety hazards.

[0041] Preferably, the controller also includes a voice control system, which is electrically connected to the temperature sensor, the photoelectric sensor, the smoke temperature sensor and the flow sensor. When the temperature sensor detects that the water temperature in the coil 2 meets the standard, the flow sensor detects that the flow rate in the water supply pipeline is 0, the smoke temperature sensor detects that the smoke temperature in the smoke exhaust duct 6 exceeds the set value, or the photoelectric sensor detects that the oil mist in the combustion chamber is not ignited, the signal is fed back to the voice control system, and the voice control system controls the heater to issue a voice prompt.
