[0002] The most common water heaters are solar water heaters and electric water heaters, and in most water heaters, the boiling water system and the hot water system are separated independently. Currently, there are a small number of integrated boiling water water heaters in the prior art. For example, CN101907364A discloses a solar energy and residential integrated boiling water water heater device, which is composed of a wall-mounted collector (15), a circulating pump (14) that transports the working fluid to a heat exchanger (17) in a water tank (16) of the water heater for circulating heat exchange, and includes a microprocessor control or an expander (20), characterized in that: a water heater tank (1) of relatively small volume is provided, an electric phase-changing valve (13) is provided on the working medium circulation pipeline, and a heat exchanger (2) arranged in the water heater tank (1) or a heat exchanger (17) arranged in the water heater tank (16) is selectively connected; a water intake (7) is provided at the bottom of the water heater tank (1), and a drainage / water replenishment port (8) is also provided, which is connected in series with a non-return electromagnetic valve to the siphon port of the siphon pump (9); the water inlet of the siphon is connected to the tap water pipe (12), and the water outlet is connected to the water heater tank (16).

DETAILED DESCRIPTION

[0017] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0018] Embodiment 1:

[0019] like Figure 1 As shown, a photovoltaic water heating and boiling water integrated machine includes a hot water tank 1 and a boiling water tank 2 integrated together, wherein the hot water tank 1 and the boiling water tank 2 are respectively provided with a first heater 11 and a second heater 21 and a first heat exchanger 12 and a second heat exchanger 22, wherein the first heater 11 and the second heater 21 are both connected to a power supply system 3, the first heat exchanger 12 is respectively connected to a cold water inlet pipe 13 and a hot water outlet pipe 14, and the second heat exchanger 22 is respectively connected to a boiling water inlet pipe 23 and a boiling water outlet pipe 24.

[0020] Specifically, the power supply system 3 is a photovoltaic power supply system, and the photovoltaic power supply system is a DC photovoltaic power supply system. The first heater 11 and the second heater 21 are both DC heaters, which can omit components such as inverters and reduce costs.

[0021] The hot water tank 1 and the boiling water tank 2 are integrated in the same housing 4, and the housing 4 is filled with a heat-insulating layer 5, which may be a polyurethane heat-insulating layer.

[0022] In some embodiments, the cold water inlet pipe 13 is connected to the hot water tank water supply pipe 15 through a tee, and the hot water tank 1 is replenished with water through the hot water tank water supply pipe 15.

[0023] In some embodiments, the hot water tank 1 and the boiling water tank 2 are connected by an anti-backflow water supply pipe 25, and the anti-backflow water supply pipe 25 supplies water to the boiling water tank 2. The anti-backflow water supply pipe 25 is a U-shaped water supply pipe, which prevents the high-temperature boiling water in the boiling water tank 2 from flowing back into the hot water tank 1 in the low-temperature area.

[0024] In some embodiments, the hot water outlet pipe 14 is connected to the boiling water inlet pipe 23 via a tee, and the hot water in the hot water outlet pipe 14 can be used to achieve rapid temperature increase.
