This hot water facility comprises water tank 401, heating tube 402, water pump 403.
The structure of described water tank 401 is identical with the water tank 301 of the function and first embodiment, has cold water inlet 404, adds hot water delivery port 405, water inlet of hot water 406, hot water outlet 407.
Different with first embodiment, this embodiment adopts heating tube 402 heating of inserting water tank 401.Described heating tube 402 places described water tank 401 tops, during the heating of this heating tube 402, can make the water around it form convection current with the water that described water tank 401 tops are higher than its installation position, the very fast heating of this part water quilt.And the water that is lower than this position can't participate in convection current, therefore is not heated.Water after the heating is placed in the top of water tank 401 naturally because density is little
This hot water facility has a water pump 403 simultaneously.This water pump adds hot water delivery port 405 cold water is extracted into the top of water tank 401 through figure from the bottom of described water tank 401, enter water tank 401 through adding hot water water inlet 406.
During this hot water facility work, utilize the mode of water pump circulation.The water of bottom is circulated to top and heats, and the water that top has heated constantly adds the bottom and draws up next cold water, and continues to be heated.The hot water layer is constantly enlarged.This method adopts the layering heating equally, and the speed of drawing water and the heating power of water pump are adapted, and guarantees that the water at top is in suitable temperature all the time.
This hot water facility can be according to grasping the speed of drawing water of water pump, heat time heating time etc. water volume that can be utilized preferably.
Above-mentioned two hot water facilities that embodiment provides are compared the heating process difference with using the hot water facility of water storage device under the prior art.Fig. 5 illustrates the difference of two kinds of mode of heatings.
Above-mentioned hot water facility provided by the invention, its common feature are that hot water method is identical, and this hot water method may further comprise the steps:
Step 1, the part water of heating water storage device is to temperature required.
Compared with prior art, mode of heating of the present invention only heats the part of all water, and prior art is then carried out the integral body heating to water all in the water storage device.
Step 2 places heated part water at the top of water storage device.
Part water for through step 1 heating utilizes the lower character of hot water density, makes it be positioned over the top of water storage device.
Step 3 when carrying out step 2, from the bottom water intaking of water storage device, and is heated to temperature required.
This step is used for making the not heated water of water storage device constantly to enter heating process.
Step 4 is returned step 2).
This step makes hot water constantly in the accumulation of water storage device top, forms the hot water layer.
Above-mentioned heating means compared with prior art, having can be according to institute's water requirement hot water, and can obtain temperature required advantages such as water within a short period of time.The hot water method of hot water method below more of the present invention and prior art.
As shown in Figure 5, the mode of heating of prior art begins heating from the bottom, reduces because the density of water raises with temperature, and therefore, the heated water density in bottom reduces, and upwards flows, and unheated water density is big and sink, and forms the convection current of water.Rely on the heat transfer type of this convection current, the water integral body of whole water storage device is evenly heated, water temperature constantly raises.The shortcoming of this mode of heating is no matter have or not demand, all need heat the water in the whole water storage device, can't be heated the water yield according to the adjustment of actual used water amount.
As shown in Figure 5, mode of heating of the present invention at first to part water heating, and will this heated water places the top of water storage device, by continuous heating, top hot water layer's volume is enlarged gradually.If the user only need use a part of hot water, then can after reaching institute's water requirement, hot water stop heating.
As can be seen from Figure 5, although all waters are identical to time of required final temperature in the heating water storage device, because that part water can be heated to very soon is temperature required, so the user is with short many of the time that obtains temperature required hot water.Use heating means of the present invention shown in Fig. 5, in the heat accumulation water yield of heating beginning back (promptly after the energising) different time.As can be seen, this kind heating means can obtain temperature required water at short notice, and can control and be heated the water yield, accomplish with how many heating what.Because adding the hot water amount meets user's demand, can avoid energy waste.Analyze from heat transfer theory, among the present invention program, water does not produce convection current in heating process.Because the minimum liquid of conductivity of heat of water, the hot water on top are difficult to produce heat exchange with the cold water of bottom by the heat conduction, therefore, the technical program can be good at realizing water temperature delamination, and avoids energy loss.
