Example Embodiment

[0028] Example 1:

[0029] The water tank of this embodiment includes an inner tank, an outer shell, and a heat exchange coil. The heat exchange coil is built in the inner tank, and the inner tank is set in the outer shell, such as Figure 1 ~ Figure 3 As shown, the liner is a double liner, and the double liner includes a hot water outlet liner 1 on the right and a cold water inlet liner 2 on the left. The hot water outlet liner The bottom of 1 is provided with a hot water outlet 3, the bottom of the cold water inlet liner 2 is provided with a cold water inlet 4, and the hot water outlet liner 1 and the cold water inlet liner 2 are connected by an inner liner connecting piece 5. The hot water outlet tank 1 is provided with a first heat exchange coil 6, and the cold water inlet tank is provided with a second heat exchange coil 7.

[0030] The first end of the first heat exchange coil 6 is communicated with the first end of the second heat exchange coil 7 outside the inner liner, and...

Example Embodiment

[0034] Example 2:

[0035] Such as Figure 4 ~ Figure 7 As shown, in this embodiment on the basis of embodiment 1, the cold water inlet liner 2 on the left side and the hot water outlet liner 1 on the right side are both provided with water temperature probes, and the cold water inlet liner A first water temperature probe 12 is provided in the middle of the surface, and a second water temperature probe 13 and a third water temperature probe 14 are respectively provided in the middle and upper part of the outer surface of the hot water outlet liner. At the same time, a first electric heating tube 15 and a second electric heating tube 16 are respectively provided in the cold water inlet liner and the hot water outlet liner, respectively.

[0036] The first water temperature probe 12, the second water temperature probe 13 and the third water temperature probe 14 display the water temperature in different positions of the inner tank in real time. During the use of hot water, when the ...

Example Embodiment

[0037] Example 3:

[0038] Such as Figure 7 As shown, on the basis of Embodiment 2, this embodiment is also provided with a hot water outlet pipe 17. The head end of the hot water outlet pipe 17 is located at the top of the hot water outlet tank 1. The hot water outlet pipe 17 The tail end is connected with the hot water outlet 3.

[0039] From the top of the cold water inlet tank 2 on the left into the hot water at the bottom of the hot water outlet tank on the right, it passes through the first heat exchange coil in the hot water outlet tank on the right to reheat the heated high temperature hot water , Flows out from the top of the hot water outlet tank through the hot water outlet pipe. The hot water outlet pipe 17 extends to the top of the hot water outlet liner 1 to take water to ensure that the hot water outlet 3 outputs high-temperature hot water, and further improves the efficiency of hot water outlet.

[0040] In addition, the bottoms of the cold water inlet liner and th...

Abstract

The invention relates to a water tank used for a heat pump hot water heater. The water tank comprises a hot water discharging liner and a cold water feeding liner, wherein the bottom of the hot water discharging liner is provided with a hot water outlet; the bottom of the cold water feeding liner is provided with a cold water inlet; the hot water discharging liner and the cold water feeding liner are connected by liner connecting pieces; a first heat exchange coil pipe is arranged in the hot water discharging liner; a second heat exchange coil pipe is arranged in the cold water feeding liner; a liner connecting water pipe is arranged between the hot water discharging liner and the cold water feeding liner; the head end of the liner connecting water pipe is positioned on the top of the cold water feeding liner; the tail end of the liner connecting water pipe is positioned on the bottom of the hot water discharging liner; the first end of the first heat exchange coil pipe and the first end of the second heat exchange coil pipe are communicated on the outsides of the liners; the second end of the first heat exchange coil pipe is provided with a Freon inlet; the second end of the second heat exchange coil pipe is provided with a Freon outlet. The hot water discharging rate of the water tank is high, and the problems of low hot water discharging rate and large size of the traditional water tank are solved.

Description

technical field [0001] The invention relates to the technical field of heat pump water heaters, in particular to a water tank for heat pump water heaters. Background technique [0002] Most of the water tanks of heat pump water heaters currently on the market are single inner tanks, the hot water output rate is generally about 75%, and the water in the water tank capacity cannot be fully utilized. Since the water tank is a pressure-bearing structure, which belongs to the top water type, during use, while hot water is flowing out of the water outlet, cold water is being fed into the water inlet at the same time, so that hot water and cold water form mixed water in the middle and lower parts of the inner tank of the water tank, and the water temperature drops rapidly. , resulting in a low rate of hot water output from the water tank outlet. When a family purchases a heat pump water heater, the configured water tank is generally too large, which causes inconvenience during the...
