Mandril 73 connects inverted cam 71 close to one end of inverted cam 71, so that anti-rotation conducting bar 74 other than the effect of anti-rotation, is gone back
The intensity of mandril 73 can be increased.
In a wherein embodiment, the outer surface of head part 70 is equipped with wearing layer.Because head part 70 can be with upper cover 20, active
Sliding friction occurs for cam 80 contributes to inverted cam 71 to be not susceptible to grind by the way that wearing layer is arranged on the outer surface of head part
Damage ensure that the stability that head part 70 moves.Preferably, wearing layer is Ni-P chemical deposits, and the thickness of Ni-P chemical deposits is
0.003-0.0038mm, hardness number are HV460~600.
In a wherein embodiment, inverted cam 71 and mandril 73 are detachably connected.By the way that inverted cam 71 and top is arranged
Bar 73 is detachably connected, when head part 70 certain a part occur frictionally damage when, as long as replace corresponding inverted cam 71 or
Mandril 73 reduces replacement cost without entire head part 70 is needed to change.Specifically, mandril 73 is close to the one of inverted cam 71
End is equipped with fixed disk, and fixed disk is connected by screw inverted cam 71, to realize the connection of mandril 73 and inverted cam 71.
As shown in figure 4, actuating cam 80 is close to the arc-shaped shape in the end face of head part 70, actuating cam 80 is close to the end of head part 70
Bathroom recess 81 corresponding with protrusion 72 and heating protrusion 82 are formed on face.Due to inverted cam 71 and actuating cam 80 that
This arc-shaped shape in close end face, therefore when the rotation of motor 60 bathroom recess 81 can match with protrusion 72 or keep heating raised
82 match with protrusion 72.
Since actuating cam 80 and the end face close to each other of inverted cam 71 are in special arc shape, the motor of the present embodiment
60 motors 60 rotated for single direction, i.e., when the mandril 73 of head part 70 stretches out upper cover 20, the protrusion 72 of inverted cam 71 is always
Walk the route that radian is longer, the gradient is more slow, when the 73 retraction lower cover 10 of mandril of head part 70, the protrusion 72 of inverted cam 71 is always
The route that radian is shorter, the gradient is steeper is walked, the torsion that motor 60 drives actuating cam 80 to rotate can be effectively reduced, extends and uses the longevity
Life, at the same also ensure that 80 normal rotation of actuating cam so that head part do up and down linear motion, will not moved because lift angle is excessive
Self-locking and " stuck " are generated in the process.
The outer circumference surface of actuating cam 80 be equipped with 41 matched bathroom contact 83 of bathroom microswitch and with heating
The matched heating contact in the contact of microswitch 43 84.Bathroom microswitch 41 and heating microswitch 43 pass through contact and master
Contact connection on moving cam 80, internal circuit communication is completed in the inside of microswitch, and internal switch connects
Head is without exposed, and the contact that is electrically connected is not easy to be corroded, to ensure the normal use of wall-hung boiler three-way valve control device.In the present embodiment
In, bathroom contact 83 is in triangle body shape with heating contact 84, this enables bathroom contact 83 and heating contact 84 to distinguish successfully
The contact for depressing the contact and heating microswitch 43 of bathroom microswitch 41, will not occur stuck phenomenon.Certain bathroom contact
83 and heating contact 84 shape be not limited only to this, in a wherein embodiment, as shown in figure 5, bathroom contact 83 and heating
Contact 84 is cylindrical shape, and the centerline axis parallel of bathroom contact 83 and heating contact 84 is in the central shaft of actuating cam 80
Line, bathroom contact 83 and heating contact 84 are rotatably set on actuating cam 80.By the way that bathroom contact 83 and heating contact is arranged
84 at cylindric setting, and is rotatably arranged on actuating cam 80, and the contact of microswitch is not only enable smoothly to be depressed,
Between bathroom contact 83 and the contact of bathroom microswitch 41 and heating contact 84 and heating microswitch 43 can also be reduced
Frictional force between contact, to the contact 84 that reduces between bathroom contact 83 and the contact of bathroom microswitch 41 and heat
Frictionally damage between the contact of heating microswitch 43.
In the present embodiment, bathroom microswitch 41 is higher than heating microswitch 43, and bathroom contact 83 is higher than heating contact
84, correspondingly, bathroom microswitch 41 is higher than heating microswitch 43.Being rotated in motor 60 drives actuating cam 80 to rotate,
Bathroom contact 83 can only press the contact of bathroom microswitch 41, and heating contact 84 can only be by the contact for the microswitch 43 that heats
It presses, effectively increases reliability when both of which is mutually converted, stable quality.
In the present embodiment, bathroom contact 83 and heating contact 84 quantity be two, heat contact 84 and positioned at touch
Point is arranged alternately along the edge of actuating cam 80, and two bathroom contacts 83 and two heating contacts 84 can realize heating, bathroom two
The frequent transitions of kind mode.
Wall-hung boiler three-way valve control device further includes fastener 92 on the mandril 73 for insert in head part 70 and is sheathed on fastener 92
Nail rod on sealing ring 93, the ailhead of fastener 92 is located at side of the head part 70 far from mounting plate 30；Sealing ring 93 is located at fastener
Between 92 ailhead and head part 70.Sealing ring 93 can prevent the sky that the water in triple valve enters upper cover 20 and lower cover 10 surrounds
Work that is interior and influencing pcb board 50, bathroom microswitch 41, heat microswitch 43 and motor 60.In the present embodiment,

Golden finger 55 heat to electricity, bathroom golden finger 54 powers off, but the microswitch 43 that heats is to disconnect, so motor 60 rests on confession
Position is warmed up, the protrusion 72 on actuating cam 80 is contacted with the heating protrusion 82 of the inverted cam 71 of head part 70, and the top of head part 70 is arrived
A high position can make water heater be in heating mode in this way；
When requiring transformation into bathroom pattern, the heating golden finger 55 of pcb board 50 powers off, and bathroom golden finger 54 gives electricity, by
It is depressed in the contact of bathroom microswitch 41, is changed into off-state, is i.e. circuit disconnects, so motor 60 rests on bathroom position
It sets, the protrusion 72 of actuating cam 80 moves to bathroom recess 81 from heating protrusion 82, under the action of bathroom recess 81, head part 70
It is down to low level, water heater can thus be made to be in bathroom pattern.
When the heating mode by giving tacit consent to is transformed into bathroom pattern, when the rotation of actuating cam 80, and bathroom contact 83 does not have also
When having and 41 contact of bathroom microswitch depressed, and switching to heating mode in advance, connected state at the microswitch 43 that heats, pcb board
50 heating golden finger 55 is rotated further to electricity, motor 60, and actuating cam 80 is driven to rotate, until the microswitch 43 that will heat
Until contact is depressed, that is, enter heating state, intermediate there is no dead points.
