According to some embodiments of the present invention, as shown in Figure 3, the shell 7 of water heater 100 can be located at outside inner bag 1, and can be provided with heat-insulation layer 70 between shell 7 and inner bag 1, thus can improve the heat-insulating property of water heater 100, reduces energy consumption and economize energy.Shell 7 is provided with shell water inlet 71, shell delivery port 73 and shell sewage draining exit 72, and shell water inlet 71, shell delivery port 73 and shell sewage draining exit 72 are corresponding with inner bag water inlet 11, inner bag delivery port 13 and inner bag sewage draining exit 12 respectively.
Below the course of work of the water heater 100 according to the specific embodiment of the invention is described in detail.
When water heater 100 normally uses, division box 4 switches to daily state, and point water water inlet 403 on control valve 42 is communicated with daily water route 401.Now, the direction of current is as shown in the dotted arrow in Fig. 4, the water entered from point water water inlet 403 first through daily water route 401 laggard enter fluidic device 3, then the daily water cavity 301 excessively that plate 32 and jet top board 33 in jet limit jointly is flow through, after flowing through the limbers 323 in jet on plate 32, enter the container cavity 101 inner bag 1 from water inlet 303, heated by heater 61 in container cavity 101.Water after heating can export from outlet pipe 62, to meet the water demand of user.
When needs carry out cleaning blowdown to water heater 100, first the knob 423 of control valve 42 is rotated, division box 4 is switched to closed condition, divide water water inlet 403 and daily water route 401 and rinse water route 402 and all disconnect, now, do not have water to enter in inner bag 1, open blowoff valve 2, the sewage in inner bag 1 is discharged.
Then control valve 42 is switched to flushing state, point water water inlet 403 is communicated with flushing water route 402.Now, the direction of current is as shown in the solid arrow in Fig. 2 and Fig. 4, the water entered from point water water inlet 403 through flushing water route 402 laggard enter fluidic device 3, after flowing through the flushed water cavity 302 that in jet, plate 32 and jet top board 33 limit jointly, eject from jet orifice 304.
Wherein, the current ejected from the jet orifice 304 jet base plate 31 rinse impurity such as the incrustation scale be deposited in inner bag 1 on diapire face, silts, and the impurity such as incrustation scale, silt is come off from inner bag 1.The current ejected from the jet orifice 304 extension 306 drive hydraulic impeller 52 to rotate, on the one hand, when hydraulic impeller 52 rotates, crushing rod 53 is driven to rotate, fragmentation is carried out to impurity such as large stretch of incrustation scales, the mouth of a river 511 of crossing that the impurity such as incrustation scale were passed through on water lining 51 is discharged from inner bag sewage draining exit 12, on the other hand, the rotation of water conservancy impeller can form whirlpool at inner bag sewage draining exit 12 place, the accumulation of impurities such as auxiliary incrustation scale, the impurity such as incrustation scale can be discharged from inner bag sewage draining exit 12 fast, realize the flushing to inner bag 1 and the impurity of discharging in inner bag 1.
Finally, rotate the knob 423 of control valve 42, division box 4 is switched to closed condition, after the sewage in inner bag 1 is all discharged, close blowoff valve 2, complete the flushing pollution discharge work of water heater 100.Rotate the knob 423 of control valve 42, division box 4 is switched to daily state, and water heater 100 just can normally use.
In sum, according to the water heater 100 of the embodiment of the present invention, by fluidic device 3 is located in inner bag 1, and division box 4 is arranged on inner bag water inlet 11 place, utilize the break-make that division box 4 controls point water water inlet 403 and daily water route 401 and rinses between water route 402, to control the flow direction entering the water of division box 4 from point water water inlet 403, when water flows into flushed water cavity 302, can eject from jet orifice 304.And, because the glassware for drinking water ejected from jet orifice 304 has certain pressure, thus can impact impurity such as the incrustation scale in inner bag 1, silts, the impurity be deposited in inner bag 1 is come off from the internal face of inner bag 1, realize the flushing to inner bag 1, the impurity come off can be discharged from inner bag sewage draining exit 12 under the drive of current.Simultaneously, by breaker being arranged on the position of contiguous inner bag sewage draining exit 12 in inner bag 1, the current utilizing jet orifice 304 to eject drive hydraulic impeller 52 to rotate, hydraulic impeller 52 drives crushing rod 53 rotate and carry out fragmentation to impurity such as large stretch of incrustation scales, and form whirlpool at inner bag sewage draining exit 12 place, thus can carry out rinsing to inner bag 1 easily and discharge the impurity in inner bag 1 up hill and dale, and then can the efficiency of heating surface be improved, bacteria breed can be avoided simultaneously, promote effluent quality, ensure that use water is healthy.
