Special low-heat loss water storage tank for air source heat pump heater

Abstract

The invention discloses a special low-heat loss water storage tank for an air source heat pump heater. The special low-heat loss water storage tank for the air source heat pump heater is provided withthree layers of shell structures, thus, heat preservation capability of a shell is enhanced, and heat loss in the water storage tank is reduced; a heat recycling device can collect heat which is lostin a heat transmission process, and can guide the heat into an inner tank; the shell of the inner tank is preheated, temperature difference between hot water and the shell of the inner tank is reduced, and heat loss is reduced further; with a ratchet mechanism in a one-way water flow water wheel, a water wheel blade can only perform one-way rotation, consequently, water is guaranteed to flow through the one-way water flow water wheel only, a thermal baffle and the one-way water flow water wheel arranged can effectively isolate the hot water in the inner tank, and thus, heat loss of the waterin the inner tank caused by heat dissipation from a water transmission pipe when getting close to a water transmission pipe is reduced; a pressure stabilization device provided can reduce pressure generated when the water in the inner tank is heated, and consequently, avoids bursting of the inner tank caused by excessive intensity of pressure in the inner tank.

Description

technical field [0001] The invention belongs to the technical field of water storage equipment for water heaters; in particular, it relates to a special water storage tank for low thermal energy loss of an air source heat pump water heater. Background technique [0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. The water storage tank for the water heater is used to store the heated hot water or to heat the cold water. In places where traditional water storage tanks are mostly of a single-layer structure with a layer of heat insulating material wrapped on the outer layer, this structure has a low heat insulation efficiency. When the water in the water storage tank is not used for a period of time, it will cool down, which is not conducive to heat dissipation. At the same time, the outer layer of the existing water storage tank does not have a preheating device...

[0002] A water heater refers to a device that raises the temperature of cold water into hot water within a certain period of time through various physical principles. The water storage tank for the water heater is used to store the heated hot water or to heat the cold water. In places where traditional water storage tanks are mostly of a single-layer structure with a layer of heat insulating material wrapped on the outer layer, this structure has a low heat insulation efficiency. When the water in the water storage tank is not used for a period of time, it will cool down, which is not conducive to heat dissipation. At the same time, the outer layer of the existing water storage tank does not have a preheating device, so that the temperature of the outer wall of the water storage is lower. When the water temperature inside the water storage tank is higher, the temperature of the water tank shell and the water temperature differ greatly. Due to the "Mpeba effect", the cooling speed of the water storage tank is greatly increased. At the same time, the existing water storage tank has no pressure buffer capacity. When the water body in the water storage tank is heated to a certain extent, the pressure in the water storage tank expands rapidly. , and then easily lead to burst damage of the water storage tank, therefore, the emergence of a water storage tank with low heat dissipation and a certain pressure buffering capacity is imminent
