Embodiment 1

[0038] Embodiment one, see figure 1 , the open storage water heater includes a water tank 91, a heating element (not shown in the figure), a hot water pipe 911, a water mixing valve 92, an overflow pipe 831, a running water pipe 811 and a water supply pipe 821, and a water mixing valve 92 The hot water inlet is connected to the hot water pipe 911 and the cold water inlet connection pipe 901, and the hot water valve arranged between the hot water pipe 911 and the water outlet pipe 921 in the mixing valve 92 is used as a control valve, and the connection between the pipe 901 and the tap water pipe 811 The indirect water control expansion device 90 and the water inlet valve 81 are connected to the normally closed water supply valve 82 between the connecting pipe 901 and the water supply pipe 821; the normally open overflow valve 83 is connected between the water supply pipe 821 and the overflow pipe 831; the water control expansion device 90 and the The dotted line between the ov...

Embodiment 2

[0042] Embodiment 2. Figure 6 is a schematic diagram of the connection structure and control principle of this embodiment. The difference between Embodiment 2 and Embodiment 1 is that the water mixing valve in Embodiment 1 is changed to a faucet-type water outlet valve 920. Between the water outlet valve 920 and the hot water pipe 99, the one-way valve 910 is used as the control valve, and the joint 9011 between the connecting pipe and the water outlet valve is replaced with a smaller pipe diameter. figure 1 The same, and adopt the water control expansion device with the structure shown in Figure 2, the structure of the stator and moving plate in the switching valve also adopts Figure 4 and Figure 4 respectively Figure 5 The reason why the connection part 9011 adopts a smaller pipe diameter here is to prevent all the water in the pipe from flowing away through the water outlet valve after the water outlet valve 920 is opened, and the hot water in the water tank cannot be eject...

Embodiment 3

[0043] Embodiment three, see Figure 7 , the difference between the third embodiment and the second embodiment is only that the one-way valve in Figure 6 is changed to Figure 7 The normally closed cut-off valve 9100 is used as the control valve, and the stop valve 9100 is controlled by the expansion wall in the water-controlled expansion device. Similarly, the stop valve 9100 can also be integrated in the switching valve together with the overflow valve and the water supply valve. Its working principle is similar to that of the above-mentioned embodiment, and will not be described here.

Abstract

The opened water storing water heater with simple structure, use convenience, high safety and long water tank life includes water tank, heating element, hot water pipe for hot water to flow out of the water tank, water draining valve, water overflow pipe, tap water pipe and water supply pipe to supply cold water to the water tank. It features connecting pipe connected to the inlet of the water draining valve, control valve connected between the connecting pipe and the hot water pipe outlet to avoid the water flow from the connecting pipe to the hot water pipe, water controlled expander connected between the connecting pipe and the tap water pipe, normally closed water valve between the connecting pipe and the water supply pipe, normally opened valve connected between the water supply pipe and the overflow pipe, water intake valve in the tap water passage, and the control of expanding wall in the water controlled expander to the valves.

Description

technical field [0001] The invention relates to a water heater, in particular to an open storage water heater. Background technique [0002] In the existing closed water storage water heater water supply system for family or hotel rooms, it includes a water tank, a water supply cold water pipe, a safety valve, a water outlet hot water pipe and a water outlet valve, wherein the water supply cold water pipe connects the water tank with the tap water pipe, and the water outlet hot water pipe Connect the water tank and the water outlet valve. The water tank is filled with hot water. The hot water is heated by heating elements (such as electric heating tubes, electromagnetic field eddy current heating elements - using the principle of electromagnetic cooker, microwave generator - using the principle of microwave oven to heat the water) Heating, heat pump heating system - the reverse work of the refrigeration system is obtained by heating and heating the air by absorbing heat ener...
