Intake to rinse inner bag 1, the almost whole inwall of inner bag 1 can be rinsed, developing result is more preferable from outlet component 4；And go out
Water stopping cap or similar structures are not provided with water assembly 4 so that the impulse force of the current sprayed from outlet component 4 is big, and developing result is good.
Alternatively, outlet component 4 includes outlet pipe 41, cleaning pipe 42 and switch assembly 5.Wherein, as shown in figure 5,
Outlet pipe 41 is provided with apopore 410 and clean-out opening 411；As shown in Fig. 2 cleaning pipe 42 is provided with the first limbers 421 and the
Two limbers 420；Cleaning pipe 42 is located in outlet pipe 41, the driving of switch assembly 5 cleaning pipe 42 or outlet pipe 41, makes cleaning
Pipe 42 can move relative to outlet pipe 41, apopore 410 be connected with the second limbers 420 or by clean-out opening 411 and
One limbers 421 connects.
In outlet component 4, outlet pipe 41 is provided with apopore 410 and clean-out opening 411, and cleaning pipe 42 is provided with the first water flowing
The limbers 420 of hole 421 and second, the socket of cleaning pipe 42 and outlet pipe 41 simultaneously can be in the presence of rotating switch components relative to going out
Water pipe 41 moves, and the apopore 410 on outlet pipe 41 is connected with the second limbers 420 on cleaning pipe 42, so as in electric heating
During hydrophone normal work, hot water by the limbers 420 of apopore 410 and second enter cleaning pipe 42 in, and from cleaning the row of pipe 42
Go out inner bag 1；Cleaning pipe 42 moves relative to outlet pipe 41, can also connect clean-out opening 411 with the first limbers 421, now
Cold water can enter from cleaning pipe 42, and by being sprayed after the first limbers 421, clean-out opening 411, inner bag 1 is sprayed.
Alternatively, as shown in figure 5, apopore 410 is arranged at the top of outlet pipe 41, clean-out opening 411 is arranged at outlet pipe
In 41 side wall；As shown in Fig. 2 the second limbers 420 is arranged at the top of cleaning pipe 42, the first limbers 421 is arranged at clearly
Wash in the side wall of pipe 42.
The limbers 420 of apopore 410 and second is separately positioned on the top of outlet pipe 41 and the top of cleaning pipe 42, so
In electric heater normal work, hot water enters outlet component 4 from top；The limbers 421 of clean-out opening 411 and first is set respectively
In the side wall of outlet pipe 41 and the side wall of cleaning pipe 42, so in cleaning, cold water sprays from the side wall of outlet component 4, spray
It is mapped in the side wall of inner bag 1, the inwall of inner bag 1 is rinsed.
Alternatively, in the present embodiment, as shown in figure 5, the body of outlet pipe 41 is provided with 4 groups of clean-out openings 411, every group of bag
3 holes of clean-out opening 411 are included, 3 clean-out openings 411 are uniform in a circumferential direction, and multiple clean-out openings are opened in the side wall of outlet pipe 41
411, hole number when increase is rinsed for water outlet, uniform fluid flow is ejected into each position of inner bag 1, it is whole interior to reach cleaning
The purpose of courage 1；The top of outlet pipe 41 is provided with 3 apopores 410, and 3 apopores 410 are uniform in a circumferential direction.Correspondingly,
As shown in Fig. 2 the body of cleaning pipe 42 is provided with 4 group of first limbers 421, every group includes 3 the first limbers 421,3 the
One limbers 421 is uniform in a circumferential direction and matches with the position of clean-out opening 411；As shown in Figure 2 and Figure 4, cleaning pipe
42 top be provided with 426,3 the second limbers 420 in 3 the second limbers 420 and apical pore it is uniform in a circumferential direction and with
The position of apopore 410 matches.Wherein, when outlet component 4 is in water outlet station, the limbers 420 of apopore 410 and second
Correspond to and be connected, clean-out opening 411 misplaces and blocked with the first limbers 421, and now the hot water in inner bag 1 can pass through apical pore
426 enter cleaning pipe 42, or enter cleaning pipe 42 by the limbers 420 of apopore 410 and second, are then managed by cleaning
42 outflows；When outlet component 4 is in washing station, clean-out opening 411 is corresponding with the first limbers 421 and is connected, apopore
410 misplace and blocked with the second limbers 420, and now cold water part can be by cleaning pipe 42, the first limbers 421 and cleaning
Hole 411 enters inner bag 1, partly can enter inner bag 1 by cleaning pipe 42 and apical pore 426.So in cleaning, cold water also can be from top
The apical pore 426 in portion sprays, and the top of inner bag 1 is cleaned, the quantity of delivery port, enables current uniformly to spray when adding cleaning
Each position of inner bag 1 is mapped to, can reach the purpose for cleaning whole inner bag 1 so that the cleaning performance of inner bag 1 is good.
Alternatively, the diameter of clean-out opening 411 is less than the diameter of the first limbers 421, and the width of apopore 410 is less than second
The width of limbers 420.Apopore 410, clean-out opening 411, the first limbers 421, the second limbers 420 are in a circumferential direction
Quantity is identical, and wherein the quantity of clean-out opening 411 is optimal at 3-6.It should be noted that the first limbers 421, clean-out opening 411
In the case of size permission, quantity is more, and the region that can be rinsed is bigger, but the gross area of the first limbers 421 can not be more than clearly
Wash the internal diameter sectional area of pipe 42 1.5 times, avoid hydraulic pressure from declining too many, influence developing result.
Alternatively, as shown in Fig. 7-Figure 10, switch assembly 5 includes valve seat 51, valve element 52 and fixing nut 53.Wherein
