Embodiment 1

[0042] Embodiment 1. Fig. 1 is a structural schematic diagram of Embodiment 1 of the storage type water heater of the present invention. Belonging to scheme two (i.e. mode three), it can be seen from Fig. 1 that the storage type water heater includes a water tank 27, a heating device (not shown in the figure), an expander 23, a water mixing valve 26, an overflow pipe 28, The cold water pipe 241, the hot water pipe 262 and the water inlet pipe 22, the hot water inlet of the mixing valve 26 is connected to the hot water pipe 262, the cold water inlet of the mixing valve is connected to the connecting pipe 251; the expansion wall of the expander 21 is connected with a control block 23. Make the control block 23 move with the expansion wall. There are racks on both sides of the control block 23, and the inner cavity of the expander communicates with the connecting pipe 251; a water inlet valve is provided between the connecting pipe 251 and the water inlet pipe 22 to control the wa...

Embodiment 2

[0046] Embodiment 2. Fig. 2 is a structural schematic diagram of Embodiment 2 of the storage type water heater of the present invention. Compared with Embodiment 1, the expander 31 in Embodiment 2 is a rubber ball, which is placed in a limit barrel, and the lower end of the control block 33 is provided with a spherical top 331 for supporting the ball, and the internal pressure of the expander When descending, the control block can move downward by its own gravity or a spring with downward elastic force arranged on the upper side of the control block, and its action principle is the same as in Embodiment 1; 362 is provided with a one-way valve 361, so when the water mixing valve 36 of the second embodiment is closed, the pipe 363 can communicate with the expander 31, and the advantage is that the water mixing valve 36 can be designed as an electric thermostat built in the water heater Mixing valve, the data about the electric constant temperature mixing valve is in the public C...

Embodiment 3

[0048] Embodiment 3. FIG. 3 is a structural schematic diagram of Embodiment 3 of the storage type water heater of the present invention. Belonging to mode 1 in scheme 1, the storage type water heater includes a water tank 47, a heating device (not shown in the figure), an expander 43, a water outlet valve 46, an overflow pipe 48, a cold water pipe 441, and a hot water pipe 462 and the water inlet pipe 42; the water inlet of the water outlet valve 46 with the water outlet pipe 461 is connected with a mixed water pipe 464, a one-way valve 463 is connected between the mixed water pipe 464 and the hot water pipe 462, and a drain pipe is used between the mixed water pipe 464 and the connecting pipe 451 452 is connected, and the inner diameter of the drain pipe 452 is relatively small, so as to avoid the short circuit of the waterway caused by the drain pipe to the hot water channel; a shut-off valve 1 used as a water inlet valve is arranged between the connecting pipe 451 and the wa...

Abstract

The invention relates to a mixed non-static pressure water heater, with long service life and central water supply function. It comprises a water bank, a heating system, an expansion device, an outlet valve, a cold water tube, a hot water tube, an overflow tube and an inlet tube, while the cold and hot water tubes are connected to the water bank and the inlet tube is connected to the tap water tube. It is characterized in that: the expansion wall of expansion device is connected to a control block whose inner chamber is connected to the connecting tube; an inlet valve is between the connecting tube and the inlet tube; a control valve is between the connecting tube and the cold water tube; a overflow valve is between the cold water tube and the overflow tube; said inlet valve, control valve, and overflow valve are controlled via their switch blocks which are linked with said control block; the outlet valve can be a mixed water valve whose hot water inlet is connected to the hot water tube and cold water inlet is connected to the connecting tube.

Description

technical field [0001] The invention relates to a water heater, in particular to a storage water heater. Background technique [0002] Existing storage type electric water heaters used in families or hotel rooms include water tanks, temperature control elements, heating devices (such as electric heating tubes, electromagnetic field eddy current heating elements-using the principle of electromagnetic cooker, Microwave generator - use the principle of microwave oven to heat water, cold medium heating system - the reverse work of the refrigeration system is to use the condenser of the refrigeration system as the heating body), in normal conditions, the tap water pipe, water tank, hot water pipe and faucet are composed A closed body, the hot water pipe can be connected with multiple faucets to realize the central water supply; when using the faucet, the hot water in the water tank will be pressed out through the faucet under the water pressure in the water pipe; this closed elec...
