The utility model can make full use of new energy sources and save conventional energy sources.

Description

Energy saving water tank

technical field

The utility model relates to a water tank, in particular to an energy-saving water tank used on a water heater.

Background technique

In current water heaters, when the new energy (solar energy or heat pump) is insufficient, and there may be users who do not need hot water, the auxiliary heating heats the whole tank of water to the set value, and the auxiliary heating wastes conventional energy; or when When the new energy is provided, the water tank has been heated to the set value by the auxiliary energy, so that the new energy cannot be fully utilized.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art and provide an energy-saving water tank that can fully utilize new energy and energy-saving conventional energy.

According to the technical solution provided by the utility model, the energy-saving water tank includes a water tank shell, a main water tank and an auxiliary water tank are arranged in the water tank shell, the auxiliary water tank is arranged above the main water tank, and the inner space of the auxiliary water tank and the inner space of the main water tank The water in the main water tank can flow into the auxiliary water tank in one direction through the one-way valve. There is a main heater in the main water tank, and an auxiliary heater in the auxiliary water tank. A water inlet connecting pipe is arranged on the wall, a water outlet connecting pipe is arranged on the tank wall of the auxiliary water tank, and a safety valve is arranged on the tank roof of the auxiliary water tank.

The main heater is a solar heat pipe heat exchanger. The secondary heater is an electric heater.

The pressure-bearing design of the water tank of the utility model can automatically replenish water and reduce the running time of the circulating pump; the hot water outlet is designed on the upper part of the water tank, and the water temperature in the upper part of the hot water storage tank itself is higher, which can maximize the utilization of resources; the design of the safety valve can ensure that the water tank There is a stable movement pressure inside: it can keep the water temperature in the auxiliary water tank at a constant value, which not only ensures that the user can use it at any time, but also saves conventional energy; at the same time, it can also ensure the full use of new energy.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described.

As shown in the figure: the energy-saving water tank includes a water tank shell 9, a main water tank 1 and an auxiliary water tank 2 are arranged in the water tank shell 9, the auxiliary water tank 2 is arranged above the main water tank 1, and the inner space of the auxiliary water tank 2 is connected to the main water tank 1. The internal spaces of the two tanks are connected by a one-way valve 5, and the water in the main water tank 1 can flow into the auxiliary water tank 2 in one direction through the one-way valve 5. The main heater 6 is arranged in the main water tank 1, and the auxiliary water tank 2 is provided with There is an auxiliary heater 3, a water inlet connection 8 is provided on the wall of the main water tank 1, a water outlet connection 4 is provided on the wall of the auxiliary water tank 2, and a safety valve 7 is provided on the top plate of the auxiliary water tank 2.

The main heater 6 is a solar heat pipe heat exchanger.

The secondary heater 3 is an electric heater.

In the utility model, when the water in the auxiliary water tank 2 is insufficient, the water in the main water tank 1 is automatically supplemented, and the water in the auxiliary water tank 2 cannot return to the main water tank 1; The heat exchange of the heater) is carried out in the auxiliary water tank 2, and the heat exchange of the main heater 6 (such as a solar heat pipe heat exchanger) using new energy is carried out in the main water tank 1; The connecting pipe 4 is located in the auxiliary water tank 2;

Normally, when the main heater 6 heats the water in the main water tank 1 to the set value, it is directly supplied to the auxiliary water tank 2 for the user to use. If the energy provided by the main heater 6 is not enough for the water temperature required by the user, the auxiliary heater The device 3 only heats the water in the auxiliary water tank 2 to keep the water temperature in the auxiliary water tank 2 at a constant value, which not only ensures that the user can use it at any time, but also saves conventional energy; when the main heater 6 cannot heat the water temperature in the main water tank 1 to the set value Value, also can make the water that enters auxiliary water tank 2 be heated by the auxiliary heater 3 driven by conventional energy again, has guaranteed the full utilization of new energy.
