Accompanying drawing the 1, the 2nd, a kind of embodiment of the utility model is contained in the structural representation on the two-tub washing machine.Fig. 3 is the present embodiment electric circuit diagram, and Fig. 4 is the structural representation of electrothermal film heating pipe.Among the figure: 1 electrothermal film heating pipe, 2 bearing supports, 3 water injection pipe assemblies, 4 outlet pipe assemblies, 5 control circuit boards, 6 cut off the water supply controls contact a, b, 7 electrothermal relays, 8 power circuits, 9 control circuits, 10 electrothermal film heating pipe bodys, 11 Electric radiant Heating Film, 12 binding posts, 13 water filling ports, 14 delivery ports.
Below in conjunction with accompanying drawing the utility model is further described.
The characteristics of this washing machine slurry device for heating electric heating membrane are to adopt electrothermal film heating pipe (1) heated scrub water, on electrothermal film heating pipe (1) two ends water filling ports (13) and delivery port (14), be connected to water injection pipe assembly (3) and outlet pipe assembly (4) respectively, slurry is injected in the electrothermal film heating pipe by water injection pipe and heats, and is flow in the tub of washing machine by outlet pipe.In the terminal pipe of outlet pipe, cut off the water supply control contact a, b(6 are housed), electrothermal relay (7) is housed on the electrothermal film heating pipe tube wall.Power circuit (8), control circuit (9) are housed on control circuit board (5); power circuit provides dc supply for control circuit; control circuit can be controlled switching on and off of electrothermal film heating pipe, but and has outlet pipe all safeguard measures such as automatic disconnection heating power supply of back or the overheated back of electrothermal film heating pipe of cutting off the water supply.
The electrothermal film heating pipe of present embodiment is that the surface of the electrothermal film heating pipe body (10) made at the glass of ∮ 41 * 300mm scribbles Electric radiant Heating Film (11) and makes, binding post (12) is housed at the two ends that scribble Electric radiant Heating Film, Electric radiant Heating Film heating when 220 volts of electric mains are added on the binding post of electrolemma heating tube two ends by control circuit, thus the slurry in the electrothermal film heating pipe pipe is flow through in heating.
The present embodiment electric wiring as shown in Figure 3, the electrical equipment detail sees Table 1.The dotted line outside is the original electric wiring of washing part, exchanges 220 volts of power supply A ends through relay J normally-closed contact J-
