Embodiment 1
[0024] Such as figure 1 As shown, one of the structural forms of the water heater is shown. This structure installs the isolation cavity 6 in the inner tank 2 to form two relatively isolated cavities. The heater 4 is installed in the isolation cavity 6. A part of the heat exchanger 5 is in the inner tank 2, and a part is in the isolation cavity 6, the baffle plate 7 is assembled on the isolation cavity 6, and the actuator is a combination of an electromagnet 8 and an iron core 9. The working principle of this scheme is: the liner 2 is filled with water through the valve 15, and when the water level is added to the float of the float switch 11 to float, the reed switch in the float switch is connected (or disconnected), thereby feeding the circuit board 12 electrical signals; when the water is full, the heater 4 decides whether to work according to the temperature inside the tank, and a temperature sensor is placed in the tank 2 to sense the water temperature in the tank 2 (thi...
Embodiment 2
[0030] Such as figure 2 As shown, in this embodiment, the same liner 2 is divided into two large and small cavities, and the PP tube used as the isolation cavity in the first embodiment is cancelled. The heater is placed in a small cavity, and there is an opening between the large and small cavities. , There is a baffle structure at the opening. Except for the cavity form and the actuator being different from the first embodiment, the working principle of this structure is completely the same. Now we will briefly introduce the working principle and structural form of the inner tank and the actuator: the inner tank 2 can be blown. Plastic molding, leaving a channel hole between the two cavities, the size can also be injection molding, or two cavities made of metal materials, connected by a welded pipe in the middle, but the cost and simplicity of the latter two methods are not as good as Blow-molded liner; the executive mechanism of this embodiment adopts heat-sensitive magne...
Embodiment 3
[0032] Such as Figure 5 As shown, the present embodiment is quite different from the previous two in that two sets of heating systems are used, and the baffle structure is omitted. Its working principle: a heater is installed in the small-volume cavity and the large-volume cavity respectively. When the water flow switch 24 senses that there is no water flow through, the preheat heater 23 works, and the water heated to the inner tank 2 reaches the set value. and when the water flow switch 24 senses that there is a water flow through the heat exchanger, the preheating heater 23 does not work, and the heater 4 works immediately (as long as there is a water flow through, no matter how much the temperature in the tank is, the heater 4 starts immediately. Heating, unless the temperature in the small-volume isolation cavity is too high, such as close to boiling, the heating is stopped). Such as Figure 5 As shown, the small-volume isolation chamber is designed on the top. This pur...
