Motor 60 is installed between installing plate 30 and lower cover 10, and the output shaft of motor 60 passes through installing plate 30, motor 60
Lead 62 welds pcb board 50 through installing plate 30.In the present embodiment, motor 60 is fixed on lower cover 10.Specifically, motor 60
Edge be provided with mounting hole 61, lower cover 10 is provided with the fixed column 12 to match with mounting hole 61, and motor 60 passes through fixed column 12
It is installed on through mounting hole 61 in lower cover 10, so that the position of motor 60 is fixed, avoids motor 60 from rocking back and forth and influence electricity
The stability that machine 60 rotates, but because motor 60 between installing plate 30 and lower cover 10, turn avoid motor 60 and teetertotter
And influence the stability of the rotation of motor 60.
Head part is used for the opening that the sanitary outfall passage of triple valve is realized under the promotion of actuating cam and heating water outlet is led to
The conversion of the opening in road, when head part 70 stretches out upper lid 20, sanitary outfall passage is blocked, and heating exhalant canal is opened；Work as head part
When being covered in 70 retractions, sanitary outfall passage is opened, and heating exhalant canal is blocked.As shown in figure 3, head part 70 include be connected from
Moving cam 71 and the push rod 73 for wearing lid 20, inverted cam 71 are used to contact with actuating cam 80；Inverted cam 71 is close to peace
The curved shape in end face of loading board 30, formation of the inverted cam 71 close to the end face of installing plate 30 have convex portion 72.
In order to prevent push rod 73 from rotating, the outer circumference surface of push rod 73 is provided with anti-rotation sliver 74, is corresponded on upper lid 20
Anti-rotation sliver 74 is provided with anti-rotation guide groove (not shown), and anti-rotation sliver 74 is slidedly arranged in anti-rotation guide groove, and anti-rotation sliver 74 is located at
Push rod 73 connects inverted cam 71 close to one end of inverted cam 71, so that anti-rotation sliver 74 in addition to the effect of anti-rotation, is gone back
The intensity of push rod 73 can be increased.
In a wherein embodiment, the outer surface of head part 70 is provided with wearing layer.Because head part 70 can be with upper lid 20, active
Sliding friction occurs for cam 80, by setting wearing layer on the outer surface of head part, contributes to inverted cam 71 to be not susceptible to grind
Damage, it 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 push rod 73 are detachably connected.By setting inverted cam 71 and top
Bar 73 is detachably connected, when frictionally damage occurs for certain part of head part 70, as long as change corresponding inverted cam 71 or
Push rod 73, without changing whole head part 70, reduce replacement cost.Specifically, push rod 73 is close to the one of inverted cam 71
End is provided with fixed disk, and fixed disk is connected by screw inverted cam 71, so as to realize the connection of push rod 73 and inverted cam 71.
As shown in figure 4, actuating cam 80, close to the curved shape in the end face of head part 70, actuating cam 80 is close to the end of head part 70
Formed with the bathroom depression 81 and heating projection 82 corresponding with convex portion 72 on face.Due to inverted cam 71 and actuating cam 80 that
This curved shape in close end face, therefore when the rotation of motor 60 bathroom depression 81 can be engaged with convex portion 72 or make heating raised
82 are engaged with convex portion 72.
Because 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 be the motor 60 that single direction rotates, i.e., when the push rod 73 of head part 70 stretches out upper lid 20, the convex portion 72 of inverted cam 71 is always
Walk the route that radian is longer, the gradient is more slow, during the 73 retraction lower cover 10 of push rod of head part 70, the convex portion 72 of inverted cam 71 is always walked
The route that radian is shorter, the gradient is steeper, can effectively reduce the torsion that motor 60 drives actuating cam 80 to rotate, and extension uses the longevity
Life, at the same also ensure that the normal rotation of actuating cam 80 so that head part do up and down linear motion, will not moved because lift angle is excessive
During produce self-locking and " stuck ".
The outer circumference surface of actuating cam 80 be provided with the bathroom contact 83 that is engaged with bathroom microswitch 41 and with heating
The heating contact 84 that the contact of microswitch 43 is engaged.Bathroom microswitch 41 and heating microswitch 43 pass through contact and master
Contact connection on moving cam 80, its 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, so as to ensure the normal use of wall-hung boiler three-way valve control device.In the present embodiment
In, bathroom contact 81 and heating contact 83 are in triangle body shape, and this enables bathroom contact 83 and heating contact 84 to distinguish successfully
The contact of bathroom microswitch 41 and the contact of heating microswitch 43 are depressed, stuck phenomenon will not occur.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 touch
Point 84 is cylindrical shape, the centerline axis parallel of bathroom contact 83 and heating contact 84 in the central axis of actuating cam 80,
Bathroom contact 83 and heating contact 84 are rotatably located on actuating cam 80.By set bathroom contact 83 and heating contact 84 into
Cylindric setting, and be rotatably arranged on actuating cam 80, not only enable the contact of microswitch smoothly to be depressed, moreover it is possible to
Reduce between bathroom contact 83 and the contact of bathroom microswitch 41 and heating contact 84 and the contact for the microswitch 43 that heats
Between frictional force, so as to reduce between bathroom contact 83 and the contact of bathroom microswitch 41 and heat contact 84 and heating
Frictionally damage between the contact of 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, accordingly, 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
Press, effectively increase reliability when both of which is mutually changed, steady 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.
