Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
Example one
As shown in fig. 1 to 4, the present invention provides a dual preheating system for a humidifier, including: an evaporation section 1, a heat recovery section 2 and a secondary preheating section 3. The evaporation part 1 is adapted to heat water, and the heat recovery part 2 is adapted to preheat the water introduced into the evaporation part 1 at a time. The secondary preheating section 3 is adapted to secondarily preheat the water introduced into the evaporation section 1. With respect to the above components, a detailed description is given below.
The evaporation part 1 is vertically arranged on a horizontal plane, the inside of the evaporation part 1 is suitable for containing water, and the evaporation part 1 is suitable for heating the water.
In order to achieve the above effects, the evaporation part 1 includes an evaporation barrel 11 and an electromagnetic heating wire 12 spirally wound around an outer wall of the evaporation barrel 11. The evaporation barrel 11 is suitable for containing water, the electromagnetic heating wire 12 is suitable for heating the barrel wall of the evaporation barrel 11, and the barrel wall of the evaporation barrel 11 transfers heat to water inwards.
The top of the evaporation barrel 11 is provided with an exhaust hole to exhaust the water vapor generated in the evaporation barrel 11.
It should be noted that the system shown in the embodiment is mainly used for a humidifier of an air conditioning unit, and in the prior art, a common humidifier generally needs to transfer water in a water tank into a heating device to be heated to boiling so as to generate a large amount of water vapor, but in actual use, a large amount of water in a normal temperature state needs a long time to be heated to boiling, and meanwhile, energy needed for heating water is also large, but the air conditioning unit consumes a large amount of energy when in use, and most of the energy is finally converted into heat energy and then directly discharged into air, and is not fully utilized.
In order to solve the problems, the invention designs a double preheating system. Specifically, the water introduced into the evaporation barrel 11 is preheated by the heat recovery unit 2 for the first time to raise the water temperature to 50 to 60 degrees, and then the water introduced into the evaporation barrel 11 is preheated by the secondary preheating unit 3 for the second time to stably raise the water temperature to 80 to 90 degrees. And finally, the water at 80-90 degrees is heated by the electromagnetic heating wire 12, so that the water can be quickly heated to boil, a large amount of energy is saved, and the electromagnetic heating water boiling kettle has good economic benefit and environmental protection potential.
The heat recovery part 2 is arranged on one side of the evaporation part 1, the heat recovery part 2 is communicated with the evaporation part 1, and the inside of the heat recovery part 2 is suitable for flowing water. One side of the heat recovery part 2 is fixedly connected with the electric control system, and the heat recovery part 2 is suitable for guiding heat generated by the electric control system during working. Through the arrangement, the heat recovery part 2 can guide the heat generated by the electric control system to heat the water in the heat recovery part 2, namely, primary preheating is realized.
In order to achieve the above effect, the heat recovery part 2 includes a preheating chamber 21 and a heat conduction assembly 22 fixedly disposed at one side of the preheating chamber 21. The preheating chamber 21 is adapted to flow water therethrough. One side of the heat conducting assembly 22 is fixedly connected with the electric control system, and the other side is inserted into the preheating tank 21, and the heat conducting assembly 22 is suitable for guiding heat of the electric control system to heat water in the preheating tank 21. Specifically, when the heat conducting assembly 22 is submerged at the water level in the preheating tank 21, the heat of the electronic control system heats the water in the preheating tank 21 through the heat conducting assembly 22. Thereby achieving the effect of preheating the water in the preheating tank 21 at one time.
In order to achieve the effect that the heat conducting assembly 22 conducts heat of the electric control system, the heat conducting assembly 22 includes a connecting plate 221 and a plurality of heat conducting fins 222 fixed on the connecting plate 221.

The heat conductive fins 222 are provided on a side of the connection plate 221 facing the preheating compartment 21, and the heat conductive fins 222 are inserted into the preheating compartment 21. With the arrangement, when the electric control system works, heat is transferred to the heat-conducting fins 222 through the connecting plates 221, and is transferred to water in the preheating tank 21 through the heat-conducting fins 222.
In order to ensure sufficient preheating of the water in the preheating chamber 21, the preheating chamber 21 comprises a preheating chamber 211 and a discharge chamber 212, a partition 213 is arranged between the preheating chamber 211 and the discharge chamber 212, and a gap is formed between the partition 213 and the top wall of the preheating chamber 21. The heat conductive fins 222 are located within the preheating chamber 211. The bottom of the preheating cavity 211 is provided with a water inlet 214, and the bottom of the discharge cavity 212 is provided with a water outlet 215. With the above arrangement, water can enter the preheating chamber 211 through the water inlet 214 and continuously pass into the submerged heat conduction fins 222, so that the heat conduction fins 222 heat the water in the preheating chamber 211 until the water overflows the top of the partition 213, enters the discharge chamber 212, and finally leaves the preheating tank 21 through the water outlet 215 at the bottom of the discharge chamber 212. In order to ensure that the liquid level in the preheating chamber 211 can completely submerge the heat conducting fins 222, the height of the top of the heat conducting fins 222 is lower than the height of the top of the partition 213.
In order to avoid the water level in the discharge chamber 212 from being too high, water is poured into the preheating chamber 211, and the water in the preheating chamber 211 enters the discharge chamber 212 when the water temperature is not over 60 ℃. The side wall of the discharge cavity 212 is opened with a water outlet 216, and the height of the water outlet 216 is lower than the top height of the partition 213. When the water level in the discharge chamber 212 is higher than the drain hole 216, the drain hole 216 is opened to drain the excess water in the discharge chamber 212, thereby preventing the above-mentioned situation.
In order to monitor the water level in the preheating chamber 21 and prevent the water in the preheating chamber 21 from overflowing the partition 213 when the temperature of the water is not 60 degrees, a water level detector 217 is provided on the top of the preheating chamber 21 and can monitor the water level in the preheating chamber 21.
The secondary preheating part 3 is arranged on the outer wall of the evaporation barrel 11, the water outlet 216 is communicated with the secondary preheating part 3, and the secondary preheating part 3 is suitable for heating water in the secondary preheating part 3 through the residual heat of the barrel wall of the evaporation barrel 11.
In order to achieve the above effect, the secondary preheating part 3 includes a waste heat recovery pipe 31, the spiral winding of the waste heat recovery pipe 31 is on the outer wall of the evaporation part 1, the waste heat recovery pipe 31 is arranged on the top of the evaporation part 1, and the electromagnetic heating wire 12 is located below the waste heat recovery pipe 31. The two ends of the waste heat recovery pipe 31 are respectively a water inlet end 32 and a water outlet end 33, and the water inlet end 32 is arranged below the water outlet end 33, so that water is fully preheated in the waste heat recovery pipe 31. The water outlet end 33 is communicated with the evaporation barrel 11, so that the water after secondary preheating is introduced into the evaporation barrel 11.
