Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described further.
As Fig. 1 to shown in 7 for water-heating valve, including valve casing 3, valve casing 3 is provided with water entering section and outlet part, and water entering section includes
The inlet valve 11 that water inlet pipe 1 and control water inlet pipe open and close；Outlet part includes the pump housing 4, water chamber 30 and outlet pipe 2；Water chamber
30 is cylindrical, is additionally provided with connection water inlet pipe and the water stream channel of water chamber in valve casing 3.
Inlet valve 11 uses electromagnetic valve, and the circuit interface of electromagnetic valve is positioned at the position of 10 in Fig. 1 and Fig. 2, passes through circuit
In cooperation car, mechanical button realizes the break-make control of electromagnetic valve.
The warm water entered from water inlet pipe 1 is in water stream channel flows into water chamber 30 more quick under the agitation of the pump housing 4
Flowing out in outlet pipe 2, the agitation of the pump housing 4 is similar to fan, can quickly be discharged by current, plays an acceleration.
Water chamber 30 is fixedly arranged above pump cover 5, and the pump housing 4 is located between pump cover 5 and water chamber 30；
The pump housing 4: as shown in Figure 3 and Figure 4, including blade 400, brushless electric machine and obstruct cover 41, intercepts and is provided with in the middle part of cover 41
" U "-shaped accommodating cylinder 410, accommodating cylinder 410 opening part is provided with sealing ring limit 412, and sealing ring limit 412 tightly presses on pump cover 5
And between water chamber 30 inwall, sealing ring limit 412 and the accommodating one-body molded setting of cylinder 410.
Wherein intercept cover 41 to be separated by the circuit part of water chamber 31 and the pump housing 4 place, and accommodating cylinder 410 and close
The one-body molded setting in seal ring limit 412, can be effectively improved the sealing intercepting cover 41, prevents steam etc. from entering coil stator.
Owing to blade 400 and p-m rotor 401 are cold, and coil stator etc. are the parts of the pump housing 4 energising, therefore
By intercepting cover 41, energising is separated with cold two parts, it is ensured that being partially in without steam of the pump housing 4 energising
State, is effectively improved service life and the safety of the pump housing 4.
In sum, by a brushless electric machine and the cooperation of obstruct cover 41, the energized part of the pump housing is made to have well
Sealability, can effectively protect the motor in the pump housing, prevent steam enter caused circuit aging of motor internal and therefore
Barrier.
Brushless electric machine: include that p-m rotor 401 and coil stator, p-m rotor 401 are embedded at accommodating cylinder 410 inwall, line
Delineation sub-set is located at accommodating cylinder 410 outer wall, and blade 400 is fixed on the surface of p-m rotor 401.
It is provided with installation room 51 in pump cover 5, in installation room 51, is provided with the circuit board of electric current, circuit in control coil stator
Plate is attached by electric conductor 6 with coil stator.
It is provided with rotating shaft 411, p-m rotor 401 and/or blade 400 in the middle part of accommodating cylinder 410 to be articulated in rotating shaft 411.
Coil stator: as shown in Figure 4, including the first steelframe 42A and the second steelframe 42B, the first steelframe and the second steelframe phase
Interworking share fixing in hot-wire coil, and produces common magnetic field on two steelframes, increases hot-wire coil to p-m rotor
Magnetic attraction.
-the first steelframe 42A: including annular underframe 421 and the some stators 420 installed for coil, stator 420 is vertical
Being fixed on annular underframe 421 surface, stator 420 prolongs annular underframe 421 and is uniformly distributed.
-the second steelframe 42B: including stator 420 and annular notched open loop underframe 422, stator 420 is vertically fixed
In open loop underframe 422 surface, stator 420 prolongs annular underframe 421 and is uniformly distributed, the stator 420 and second of the first steelframe 42A
Stator 420 setting interlaced with each other of steelframe 42B and contactless.
First steelframe 42A is for strengthening the electromagnetic field of hot-wire coil, and its annular underframe 421 uses the annular closed to be i.e. to use
In the magnetic field, magnetic field of coil being concentrated inside steelframe so that it is magnetic strength is more preferable.
Second steelframe 42B is then the structural strength for increasing steelframe, if the underframe in the second steelframe uses closed loop, then
Can form vortex ring in underframe, cancel out each other in the magnetic field forming the annular underframe 421 in the first steelframe 42A, therefore
The open loop underframe 422 of the second steelframe 42B, for carrying open loop structure jaggy, can effectively prevent eddy current from producing.
And the stator on two steelframes is the winding for solenoid, it is crisscross arranged and contactless, also for
Avoid eddy current to produce, and many materials can be saved, reduce weight.
The most curved structure of stator 420 of the stator 420 and the second steelframe 42B of the first steelframe 42A, and first,
The stator 420 of two steelframes is respectively positioned in the annular surface with first-class circle, it is simple to the winding of hot-wire coil.
The stator 420 of first, second steelframe is the most triangular in shape or trapezoidal, it is contemplated herein that to owing to stator 420 is in punching
When backfin is curved, its structural strength is compared square the most firm, therefore the stator in the present embodiment uses triangle or trapezoidal.
First, second steelframe and stator thereon all use stalloy, and the ferrum of non-generic or steel, according to common
Steel or ferrum, during using for a long time, iron and steel can be magnetized and become permanent magnet, after causing electric current to magnetize when change direction
Iron and steel reaction relatively slow, therefore use the silicon steel material of demagnetic stack.
The above makes the preferred embodiment of the present invention, for the person of ordinary skill of the art without departing from this
On the premise of bright principle, it is also possible to make some modification and improvement, these also should be regarded as protection scope of the present invention.
