The controller 2 of the heating vessel of the visible type for including molded plastics unit 4 in Fig. 1 and Fig. 2, the most flat metal mounting plate 6 is attached to this molded plastics unit 4.Molded plastics unit 4 includes 360 ° of wireless electric connectors 8 (visible in Fig. 2), and these 360 ° of wireless electric connectors 8 make power supply be connectable to controller 2.Wireless electric connector 8 is surrounded by the cylindrical side wall 44 being molded in plastic unit 4.Though the most invisible, molded plastics unit 4 accommodates at least one switch, and this at least one switch can be disconnected to cut off power supply.Power supply circuit including at least one switch is terminated by a pair electric terminal 10a, 10b, and this pair electric terminal 10a, 10b make other electricity parts that power supply is connectable in heating element heater or heating vessel.

In Fig. 1 with Fig. 2, visible controller works in the way of similar with the U18 Series Controller of applicant, is referred to the general operation principle disclosed in WO 95/34187.Although the feature of the controller 2 the most substantially learnt from prior art will be described the most in further detail herein, but it can be seen that, controller 2 includes the interruption pole 12 that spring is installed, and this interruption pole 12 provides the manual operation of at least one switch in power supply circuit.And it can be observed from fig. 2 that the sensitive bimetallic actuator 14 of steam is arranged on an end of molded plastics unit 4, and be set in heating vessel being detected boiling time operation interruption pole 12.

As seen in Figure 1, on the upper surface of metal mounting plate 6, there is the first bimetallic actuator 15a and the second bimetallic actuator 15b location.Two bimetallic actuators 15a, 15b provide overheat protective function to controller 2.It will be seen that metal mounting plate 6 includes three holes 16a, 16b, 16c, it such as uses from the downside of pedestal prominent studs of installing to allow installing plate 6 and then be controller 2 pedestal that is fastened to heating vessel.When controller 2 is against the pedestal fastening of heating vessel, the first bimetallic actuator 15a and the second bimetallic actuator 15b keeps thermally contacting with the pedestal of heating, in order to sensitive to its temperature.First bimetallic actuator 15a is set to reaching first, relatively low temperature time operation, therefore primary overtemperature protection is provided.Second bimetallic actuator 15b is set to reaching second, higher temperature time operation, therefore secondary overtemperature protection is provided.This overtemperature protection is also required to being probably in the case of its supply electric power when the most even heating vessel is empty.In this controller 2, the first bimetallic actuator 15a is typically provided as operating the first switch being contained in inside molded plastics unit 4, this first neutral side switching off power supply.The neutral side of power supply can be provided by the ring 18 of wireless electric connector 8.Second bimetallic actuator 15b is typically provided as the second switch that operation disconnects the hot side of power supply, and this second switch can be provided by the pin 20 of wireless electric connector 8.These features visible in Fig. 2.

From Fig. 1 it can be seen that the first bimetallic actuator 15a has substantial circular shape, and the second bimetallic actuator 15b has rectangular shape.First bimetallic actuator 15a and the second bimetallic actuator 15b is both the snap-action actuator of concave surface.The substantial circular shape of the first bimetallic actuator 15a provides the circular edge of the base into contact heated with heating vessel, it means that bimetallic actuator 15a can quickly respond overheating conditions.On the other hand, the rectangular shape of the second bimetallic actuator 15b means that bimetallic actuator 15b has and four differences of the base into contact heated, and therefore the possible less efficient of conduction of heat is a little.But, when the second bimetallic actuator 15b performs secondary overtemperature protection, it is provided that quickly response is not crucial.First bimetallic actuator 15a operation is that the advantage of the neutral side disconnecting power supply before hot side is, it is to avoid the risk from the contact of corresponding first switch to metal parts (the such as metal mounting plate 6) arc discharge of any ground connection.On the side relative with voltage source of electrical load, therefore between this first switch and ground wire, there is not electric potential difference in the first switch in neutral side.This eliminates the probability of arc discharge when disconnecting the contact of the first switch.If power supply circuit cuts off alternatively by the second switch disconnected in hot side, then can there is the trend of arc discharge (i.e. shorted to earth), it causes the rapid electric discharge of electric energy.Interruption pole 12 is also configured as preferentially operating the first switch of the neutral side disconnecting power supply.

Fig. 3 shows the molded plastics unit 4 of controller 2, and wherein metal mounting plate 6 is removed.It may now be seen that molded plastics unit 4 includes a pair masked segment 22, it orientates the arc discharge stopped from being contained in the first switch inside molded plastics unit 4 and second switch to metal mounting plate 6 as.One be seen in detail in masked segment 22 in the cross section, close shot figure of Fig. 4.From fig. 4 it can be seen that masked segment 22 includes being parallel to the most flat top board 24 that metal mounting plate 6 extends and the lateral wall 26 extended from top board 24 downward (i.e. away from metal mounting plate 6).It will be seen that one in the switch 28 accommodated by molded plastics unit 4 is contained in masked segment 22.Switch 28 is substantially identical with the switch in the standard U18 controller as described in WO 95/34187, i.e. switch 28 includes fixed contact 28a and the movable contact 28b being arranged in leaf spring 30.Leaf spring 30 is bent downwardly when being acted on by push rod 32, and to disconnect switch 28, push rod 32 is moved by operation bimetallic actuator 15a, 15b (not shown in Fig. 4).Owing to top board 24 and the sidewall 26 of masked segment 22 extend around switch 28, and between switch 28 and metal mounting plate 6, provide barrier, therefore prevent the arc discharge from switch 28 to metal mounting plate 6.Thus, if switch 28 is connected to the live wire electrode of power supply and disconnects cutting off power supply, the risk launch aed surprise attack the most over the ground.

For comparative purpose, Fig. 5 provides the similar close shot of the prior art controller of such as U18 Series Controller, cross-sectional view.It will be seen that in the prior art, the sheet of mylar 34 is inserted between switch 28 and metal mounting plate 6, to lower the risk that arc discharge occurs between which.But, the sheet of this mylar 34 will not provide and the protection of masked segment seen in fig. 4 22 same levels.And, insert the polyester sheet 34 as additional components in the controller and have fringe cost and built-up time.

Referring back to Fig. 1 and Fig. 2, it can be seen that molded plastics unit 4 farther includes a pair pivoting hole 36, it is used for manual ON/OFF actuator is installed.Fig. 6 provides the cross-sectional view with the controller 2 using the manual ON/OFF actuator 38 installed with molded plastics unit 4 all-in-one-piece pivoting hole 36.It will be seen that each tapered in its porch in pivoting hole 36, to contribute to positioning the pivotal pin 40 of ON/OFF actuator 38.ON/OFF actuator 38 is pivotally mounted to molded plastics unit 4 by pin 40, with outwardly from controller 2, and ON/OFF rocking bar 42 is provided, user can close, to be set in by interruption pole 12, each position to be stirred being contained in the switch 28 inside molded plastics unit 4 by this ON/OFF rocking bar 42 of following pressure.So open the power supply of controller 2, until an operation in bimetallic actuator or use rocking bar 42 manually discharge interruption pole 12, thus disconnect (or both) switched in 28, to cut off power supply.It will be seen that manual ON/OFF actuator 38 is mounted above molded plastics unit 4 at interruption pole 12 so that interruption pole 12 is generally located between pivoting hole 36 and metal mounting plate 6.From Fig. 6 it can further be seen that pivoting hole 36 is formed at the cylindrical side wall 44 of wireless electric connector 8.Pivoting hole 36 and the integral intensity that ensure that them of molded plastics unit 4, additionally it is possible to make the ON/OFF actuator 38 set-up mode at the top of interruption pole 12 compact.Thus, make the whole height of controller 2 minimize so that the pedestal compartment needed for accommodating controller in heating vessel can also be made to be kept as less.

Fig. 7 shows the first modification of controller 2 as previously described with reference to fig. 2, and wherein electric wire 50 is guided by the side along controller 2, a series of recess 52a, 52b, the 52c along substantially straight line path alignment.Recess 52a, 52b, 52c are arranged in the alar part 54 of molded plastics unit 4.It will be seen that the alar part 54 on the either side of controller 2 laterally extends between the medial wall provided by the cylindrical side wall 44 of wireless electric connector 8 and lateral wall 56.It is appreciated that alar part 54 also includes the masked segment 22 having been described above by comparison diagram 2 and Fig. 7.Controller 2 is included on the both sides of wireless electric connector 8 a pair alar part 54 being symmetrically positioned.Therefore, a pair corresponding electric wire 50 can be guided by two alar parts 54, either side along controller 2 is extended, such as being connected to by the indicator lamp of manual ON/OFF actuator position so that sidewall or its pedestal compartment by heating vessel are visible.

See the controller 102 of the second modification in figs. 8 and 9.The controller 102 of this modification is similar with the controller 2 having been described above with reference to Fig. 1-4 and Fig. 6-7, therefore will only describe those different features now.In this controller 102, the alar part 154 of molded plastics unit 104 also laterally extends between the medial wall provided by the cylindrical wall 44 of wireless electric connector 8 and lateral wall 56.But, these alar parts 154 provide the different guide group for electric wire 50.Each including in alar part 154 may be used for retraining a pair first clip 58a and the second clip 58b of electric wire 50.It addition, each including in alar part 154 is formed at the recess 60 in lateral sidewall 62, this lateral sidewall extends between medial wall 44 and lateral wall 56.Recess 60 can optionally be used as line guide.It will be seen from figure 9 that these recesses 60 vertically extended help to guide in electric wire 50 when two lines 50 of expectation are down through the same side of controller 102.

Fig. 8 shows the first example of line guided mode, and wherein the first and second electric wires 50 are guided dividually by the alar part 154 on the either side of controller 102.Each line 50 is only bonded on below the first clip 58a and the second clip 58b of in alar part 154 on the side of controller 102.Fig. 9 shows the second example of line guided mode, wherein the first and second electric wires 50 are all only guided (as shown in the right-hand side in Fig. 9 by the first identical clip 58a and the second clip 58b of the alar part 154 on the side of controller 102, but the most alternatively, two lines 50 can guide along left-hand side).In line 50 one is guided through after wireless electric connector 8 and by the recess in the lateral sidewall 62 of alar part 154 by crossing, is feasible be close to another line 50 to extend below clip 58a, 58b.So allowing electric power to be supplied by the electric wire 50 being connected to indicator lamp, this indicator lamp is positioned on arbitrary left hand or the right-hand side of heating vessel, rather than Central places location, the most typically it is close to manual ON/OFF actuator position.Therefore, the controller 102 of this second modification provides greater flexibility in guiding electric wire 50 direction, thus, using identical molded plastics unit 104, they extend (as seen in Figure 9) on the side of controller 102 or extend (as seen in Figure 8) dividually on the either side of controller 102.
