Description

An energy storage ball electric water heater

【Technical field】

The utility model relates to an energy storage ball electric water heater, in particular to a household energy storage ball volumetric electric water heater.

【Background technique】

General household electric water heaters can be divided into instant electric water heaters and volumetric electric water heaters structurally. The instant electric water heater is generally greater than 7000W to ensure the hot water output. For the indoor grid load of residential buildings, the load is not enough. It is bound to re-lay special lines and apply to the power supply department for power increase. It is unacceptable to say that the volumetric electric water heater stores water in the inner tank of the water tank, and provides hot water by heating the water stored in the inner tank, so it needs a large volume to store water, so the space occupied by the water heater is very large. Big, and the water takes a long time to heat up (preheat). If it is necessary to reduce the preheating time, the electric heating element in the volumetric electric water heater needs to use a high-power element to reduce the preheating time, which is unacceptable to users as mentioned above. With the development and progress of society, consumers have higher and higher requirements for space, and it is more and more difficult for ordinary household volumetric electric water heaters to meet the requirements of consumers due to their shortcomings such as large volume.

【Content of invention】

The purpose of the utility model is to provide an electric water heater with good heating performance, short heating time and small volume in order to solve the disadvantages of large volume of domestic volumetric electric water heaters.

The purpose of this utility model is achieved in that:

An energy-storage spherical electric water heater, comprising a shell and an inner tank, the upper and lower ends of the inner tank are equipped with outlet pipes and water inlet pipes, and an electric heating element for heating water is installed in the inner tank, and the feature is that the water in the inner tank is A plurality of energy storage balls are placed, and a phase change heat storage material is installed in the energy storage balls.

An energy storage ball electric water heater as described above is characterized in that the shell of the energy storage ball can be made of plastic or metal material.

The above-mentioned energy storage ball electric water heater is characterized in that the energy storage ball is equipped with a phase change heat storage material with a phase change point between 30°C and 100°C.

An energy storage ball electric water heater as described above is characterized in that the energy storage balls are irregularly arranged in the inner tank.

The advantage of the utility model is that the volume of the water heater is reduced, and the heating time is fast, and the hot water heated Large quantity, simple structure, good safety performance and long service life.

【Description of drawings】

Below in conjunction with accompanying drawing, the utility model is further described.

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

【Detailed ways】

An energy storage ball electric water heater, comprising a shell 1, an inner container 2, the upper and lower ends of the inner container 2 are equipped with a water outlet pipe 5 and a water inlet pipe 6, and an electric heating element 7 for heating water is installed in the inner container 2. A plurality of energy storage balls 3 are placed in the water in the bladder 2, and a phase change heat storage material is housed in the energy storage balls 3.

During heat storage and preheating, the electric heating element 7 quickly heats the water 4 in the inner tank 2 to the corresponding temperature, and conducts heat exchange with the energy storage ball 3, and the phase change heat storage material in the energy storage ball 3 absorbs heat and generates heat. phase change, storing thermal energy. When hot water is needed, pour cold water into the inner container 2 through the water inlet pipe 6, and eject the hot water from the outlet pipe 5. 2. When the temperature inside drops to the phase transition point, heat is released, which makes the heating speed faster and the heating performance better.

The shell of energy storage ball 3 can be made of plastics or metal material.

The phase change heat storage material in the energy storage ball 3 is a phase change heat storage material with a phase change point between 30°C and 100°C.

The energy storage balls 3 can be spherical and irregularly arranged in the liner 2 .
