See Figure 22, water flow switch 68 mainly comprises dried spring induction tube 681 and the inner float 683 that magnet 684 is housed.After removing the front case shell 61 of water tank 6, can see the installation site of dried spring induction tube 681 of the water flow switch 68 of water inlet end 651, two dried spring induction tubes 681 of water flow switch 68 are installed in the outside of water inlet end 651, and add two superinsulation epoxy resin boards 682 between the cubic stainless steel outer surface of water inlet end 651, to improve the insulating capacity of dried spring induction tube 681.Water inlet end 651 is interior has installed the float 683 that magnet 684 is equipped with in an inside, and water opening part around the float 683 enters water tank 6.When not opening feed cock, the deadweight of float 683 is so that float 683 drops on the position of water inlet end bottom back-up ring 685, dried spring induction tube 681 inductions less than, circuit is obstructed, can not heat.If open into the water tap, the hydraulic pressure of water inlet upwards is flushed to dried spring induction tube 681 sensed positions to float 683, and dried spring induction tube 681 is sensed the magnet suction of float 683, and dried spring induction tube 681 is connected, and circuit is connected, and begins heating.
See Figure 22 and Figure 25; the automatically reset operation principle of thermal circuit beraker 69 of anti-scald is as follows: when output water temperature reaches 55 ℃; water temperature sees through the Stainless Steel Shell of water side 652; see through again additional heat conductive silica gel 691; conduct to the thermal circuit beraker 69 that automatically resets; the thermal circuit beraker 69 that automatically resets just oneself disconnects immediately, by line cut-off signal is transferred to circuit board and protects accordingly socket to come deenergization.Be lower than automatic pick behind its reset temperature (greatly about 45 ℃) when water temperature, Power resumption, recovery heating.The automatically reset protection philosophy of thermal circuit beraker of anti-scald that Here it is.
See equally Figure 22 and Figure 25; the operation principle of anti-dry hand-reset thermal circuit beraker 610 is as follows: when output water temperature reaches 95 ℃; water temperature sees through the Stainless Steel Shell of water side 652; see through again additional heat conductive silica gel 611; conduct to hand-reset thermal circuit beraker 610; hand-reset thermal circuit beraker 610 just disconnects immediately, by line cut-off signal is transferred to circuit board and protects accordingly socket to come deenergization.Behind the deenergization, must casing be opened by the professional, manually press SR 612 after the maintenance and inspection and just can recover to use.This protection is for the second layer protection of the thermal circuit beraker 69 that prevents from automatically reseting after damaging.Generally speaking, when water temperature surpasses 55 ℃, the thermal circuit beraker 69 that the automatically resets deenergization that just works, and the hand-reset thermal circuit beraker 610 of 95 ℃ of protections is just inoperative.After the thermal circuit beraker 69 that automatically resets of 55 ℃ of protections broke down, this hand-reset thermal circuit beraker 610 just worked, and disconnected power down source just can't be used after this action, must be torn open by the professional to re-use after machine check keeps in repair.
More than three protective devices; comprise the water flow switch 68 on the water inlet end 651; anti-scald on the water side 652 automatically reset thermal circuit beraker 69 and anti-dry hand-reset thermal circuit beraker 610; all be to utilize the induction of oneself to cut-off adhesive; again this signal is connected to circuit board by connection and comes deenergization; so the line of these three protective devices can be adopted series system; utilize double screw 613 and the nut 614 of doing signal transmission to be connected on the same corresponding protection socket of circuit board with the line that is welded on these nuts 614; any one protects action, can deenergization.This signal voltage only has 6V, is safe voltage class, adds epoxy resin board 682 and the heat conductive silica gel 691 of superinsulation, and insulating capacity surpasses II class degree of protection.
This protective device with three types is connected in series to same protection port; the centre utilizes double screw and the nut of doing the signal transmission; both realized the transmission of signal; also realized the main frame of two independent sealings and the removable connection between the water tank, this design has realized pull-out type self-contained water tank structure.
