Detailed Description
Example 1
1-2, a water tank self-circulation heating device, a water storage tank 1, a heating container 2 and a heating component, it should be understood that a water storage pipe is provided with a water adding pipe 101 for adding water into the tank, a drain pipe 102 for emptying, an overflow port 103 can be arranged at the upper part of the water storage tank 1, and the overflow port 103 is arranged, so that on one hand, evaporation and removal of part of water are facilitated, and the pressure in the tank is prevented from being influenced; on the other hand, when water is added, water overflows, which means that the maximum water level is increased.
The heating vessel 2 comprises an inner metal layer 201 and an outer insulating layer 202, the outer insulating layer 202 isolating the connection to the metal against electric shock, and alternatively the outer insulating layer 202 is ceramic.
The heating component comprises a heating conductor 4 arranged in the heating container 2 and a high-frequency heating coil 3 arranged outside the heating container 2, the heating conductor 4 can be supported at the bottom of the heating container 2 through a plurality of supporting pieces 10, two ends of the high-frequency heating coil 3 are connected with high-frequency heating equipment, in practical application, the high-frequency heating coil 3 is generally a copper pipe, and when the high-frequency heating component is in operation, the high-frequency heating coil 3 is supplied with high-frequency current to enable the heating conductor 4 to heat and heat cold water, namely, the high-frequency heating type heating device adopts a high-frequency heating mode, and compared with the prior art, the high-frequency heating device has the advantages of smaller energy loss and higher heating efficiency.
The bottom end of the heating container 2 is provided with a cold water inlet 9, the top end of the heating container is provided with a hot water outlet, the lower part of the water storage tank 1 is provided with a water outlet, the upper part of the water storage tank is provided with a water return port, the cold water inlet 9 is communicated with the water outlet through a water outlet pipeline 5, and the hot water outlet is communicated with the water return port through a water return pipeline 6; further, the water return port, the water outlet pipeline 5, the water return pipeline 6 and the heating container 2 are all positioned below the liquid level of the water storage tank 1.
It should be noted that, according to the above arrangement, the cold water and the hot water can be circulated without external energy source, i.e. the cold water in the storage tank is heated after entering the heating container 2 through the water storage pipeline, and the hot water returns to the water storage tank 1 through the water return pipeline 6, by using the principle of the communicating vessel and the principle of cold and hot convection, and the circulation is repeated until the water in the water storage tank 1 is heated to the required temperature.
On the basis of the above, the heating container 2 of the embodiment has a conical structure with a big upper part and a small lower part, so that on one hand, cold water is heated faster due to the small space at the lower end; on the other hand, the heated water rises rapidly, the cold water on the upper layer sinks rapidly, so that the cold water and the hot water are convenient to flow rapidly, and the hot water also conveniently enters the water return pipeline 6 rapidly and returns to the water storage tank 1.
Further, in the embodiment, the heating conductor 4 has a tapered structure with a small upper end and a large lower end, and it is worth to say that, because the space at the lower end of the heating container 2 is small, and the lower end of the heating conductor 4 is large, that is, the heating area is large, so that the heating speed of the lower end of the heating container 2 is further increased, and the heating speed is slower than the lower end under the condition that the space at the upper end of the heating container 2 is large and the heating area is large, so that the overall heating speed is ensured, and meanwhile, the water heated at the lower end is quickly increased.
Example two
The embodiment is further optimized based on the first embodiment, specifically, the upper end of the heating container 2 is provided with an upper connecting flange 7, the hot water outlet is arranged on the upper connecting flange 7, and the diameter of the hot water outlet is equal to the inner diameter of the upper end of the heating container 2, so that the upper hot water can directly enter the water return pipeline 6.
The bottom of the heating container 2 of this embodiment is provided with a lower connecting flange 8, referring to fig. 3, the lower connecting flange 8 is provided with a plurality of cold water inlets 9, even if cold water enters the heating container 2 through a plurality of small openings, the arrangement is such that, on one hand, the speed of cold water entering the heating container 2 is slowed down to a certain extent, so that the cold water at the lower end of the heating container 2 is sufficiently heated; on the other hand, since the water in the heating vessel 2 tends to enter the water outlet line 5 downward, the several lower ports also suppress the downward flow rate to some extent, i.e., this tendency is suppressed. Further, in this embodiment, the apertures of the plurality of cold water inlets 9 gradually increase from the center to the edge of the lower connecting flange 8, and it is worth to be noted that, in general, the water flow rate is the largest at the center of the pipeline, and the lower the flow rate is near the side wall of the pipeline, the smaller the center of the lower connecting flange 8 is, the larger the position is near the edge, so that the effect can be better achieved while ensuring a certain water inlet speed.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
