Description

Technical Field

[0001] The invention relates to the field of water heaters, in particular to a sanitary energy storage type heat pump water heater. Background Art

[0002] The tap water abroad is direct drinking water. Users will drink the tap water directly after it passes through the heat pump water tank. That is, the tap water is first transported to the inside of the heat pump water tank, and then the heat pump host is turned on to heat the tap water in the heat pump water tank. After the tap water is heated, it becomes domestic hot water that users can drink directly.

[0003] However, under this method, the heat pump water tank has a certain volume, and the user will not use up the tap water in the heat pump water tank at one time. Therefore, a certain amount of tap water will remain in the heat pump water tank. There are certain microorganisms in the tap water. The maximum water outlet temperature of the heat pump is 65°C, which will produce various bacteria and scale after the tap water is heated for a long time in the heat pump water tank, and the inner tank of the heat pump water tank will be corroded. In addition, in order to ensure that the inner tank of the heat pump water tank is not corroded, the equipment manufacturer will use magnesium rods to protect the inner tank. However, the magnesium rods will release and consume to protect the inner tank during use, so that the tap water in the heat pump water tank will be polluted to a certain extent, which will cause health problems for users to drink directly. To address the above problems, we propose a water sanitation energy storage heat pump water heater. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art that directly storing water in a heat pump water tank will cause various bacteria and scale to appear inside the heat pump water tank, thereby affecting the hygiene and safety of the tap water in the heat pump water tank, and to propose a water hygiene energy storage heat pump water heater.

[0008] Energy storage ball bodies, multiple groups of energy storage ball bodies are stored inside the storage cavity;

[0009] The water-to-water heat exchange coil is arranged inside the water storage tank. The heat of the energy storage ball body is transferred to the water flowing through the water-to-water heat exchange coil through the water-to-water heat exchange coil.

[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The present invention provides a water sanitation energy storage heat pump water heater, see Figure 1-3 Specifically, it includes a water heater body 1, a heat pump host 31 and a water tank 4 arranged inside the water heater body 1, a condensing coil 41 is arranged inside the water tank 4, a first cavity 2 and a second cavity 3 are opened inside the water heater body 1, the water tank 4 and the heat pump host 31 are respectively arranged inside the first cavity 2 and the second cavity 3, and the first cavity 2 and the second cavity 3 are in two independent cavities. By turning on the heat pump host 31, the tap water inside the water tank 4 can be heated, and the condensing coil 41 arranged inside the water tank 4 can adjust the heating temperature of the tap water, thereby meeting the different water temperature requirements of users.

[0023] See attached Figure 2-3 A protective mechanism 5 is arranged inside the water storage tank 4. By means of the protective mechanism 5, the water storage method in the traditional water storage tank 4 is eliminated, so that the effect of heating water without storing water is achieved, and the scaling of water and the generation of water bacteria in the water storage tank 4 are avoided. Moreover, because no water is stored in the water storage tank 4, the use of magnesium rods can be eliminated, thereby reducing the pollution of the heated water body. The protective mechanism 5 includes a storage cavity 51. The storage cavity 51 is opened at both ends of the water storage tank 4. A plurality of energy storage ball bodies 52 are stored inside the storage cavity 51. The operation of the energy storage ball body 52 is mainly controlled by the heat pump host 31. After the energy storage ball body 52 is in operation, a large amount of heat will be generated. If the user has no water demand for the time being, When the water is heated, the heat is stored in the energy storage ball body 52. ​​When the user needs water, the energy storage ball body 52 releases heat to heat the tap water. The water-to-water heat exchange coil 54 is arranged inside the water storage tank 4. The heat of the energy storage ball body 52 is transferred to the tap water flowing through the water-to-water heat exchange coil 54 through the water-to-water heat exchange coil 54. The number of water-to-water heat exchange coils 54 is not limited, and one or more groups can be arranged. The condensing coil 41 is wound around the outside of the water-to-water heat exchange coil 54. The outer wall of the water heater body 1 is provided with an energy storage ball flange port 53 connected to the inside of the water storage tank 4. Multiple groups of energy storage ball bodies 52 are fed into the storage cavity 51 through the energy storage ball flange port 53.

[0024] See attached Figure 1 and attached Figure 3 The two ends of the water-to-water heat exchange coil 54 are respectively connected to a cold water inlet pipe 6 and a hot water outlet pipe 7. One end of the cold water inlet pipe 6 and the hot water outlet pipe 7 extend to the outside of the water heater body 1. The cold water inlet pipe 6 transports tap water to the inside of the water-to-water heat exchange coil 54. The tap water that has completed the heat exchange is heated into domestic hot water, so that the domestic hot water can be transported to the place of use through the hot water outlet pipe 7.

[0025] Specifically, the working principle and operation method of the present invention are as follows:

[0026] Before using the sanitary energy storage heat pump water heater, a plurality of energy storage ball bodies 52 are first placed into the water tank 4 through the energy storage ball flange opening 53, so that a plurality of energy storage ball bodies 52 are respectively stored in the storage chambers 51 opened at both ends of the water tank 4, and then the energy storage ball flange opening 53 is closed by a seal. The seal is not specifically drawn in the accompanying drawings. The type of seal is mainly selected according to actual needs. The present invention does not impose specific restrictions on the seal.

[0027] Furthermore, when the flange 53 of the energy storage ball is placed into the water tank 4 , the heat pump host 31 is turned on, so that the heat pump host 31 controls the energy storage ball body 52 to heat up. After the energy storage ball body 52 is heated, a large amount of heat will be transferred into the water tank 4 .

[0028] Furthermore, when the energy storage ball body 52 is heated, the tap water is transported to the inside of the water-to-water heat exchange coil 54 through the cold water inlet pipe 6, so that the tap water circulates inside the water-to-water heat exchange coil 54. During this process, the heat at the energy storage ball body 52 can be transferred to the tap water flowing through the water-to-water heat exchange coil 54 through the water-to-water heat exchange coil 54, so that the tap water can be heated.

[0029] Finally, when the tap water is heated, the required domestic hot water is formed, and the domestic hot water can be transported to the required usage location through the hot water outlet pipe 7. During the above process, there is no need to add tap water inside the water storage tank 4, and the tap water only flows in the water-to-water heat exchange coil 54.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
