Spiral plate type bearing water tank

Abstract

A spiral plate pressure water storage tank is characterized in that an inner container of a pressure water tank is set as a cylinder body, a deflector is spirally arranged by surrounding a shaft line of the cylinder body, a cold water port is formed on the side wall of the bottom part of the inner container of pressure water tank and positioned in a bottom layer of the deflector, a hot water port is formed on the side wall of the top part of the inner container of the pressure water tank and positioned in a top layer of the deflector, and a spiral water flow channel is formed along the deflector between the cold water port and the hot water port. The spiral plate pressure water storage tank can not only retain the advantages on the water supply pressure aspect of the pressure water tank, but also effectively improve the hot water efficiency, simultaneously simplify the structure, reduce the cost and miniaturize the water tank.

Description

technical field [0001] The invention relates to a water storage device of a heat pump water heating unit using air as a heat source, in particular to a pressurized water storage tank in the heat pump water heating unit. Background technique [0002] The water storage tanks of the existing air source heat pump hot water units are divided into two types: pressure-bearing type and non-pressure-bearing type. [0003] The non-pressurized water storage tank uses a water supply pump to supply hot water, and the hot water utilization rate is high, up to 100%, but it needs to be equipped with a water supply pump, so it has the following disadvantages: [0004] 1. It is difficult to match the water supply pressure of the water supply pump with the tap water pressure, and it is difficult to mix the water during use; [0005] 2. The weight and volume of the water supply pump are large, which is not conducive to the miniaturization of the unit; [0006] 3. The price of the water supply...

AI Technical Summary

Problems solved by technology

[0004] 1. It is difficult to match the water supply pressure of the water supply pump with the tap water pressure, and it is difficult to mix the water during use;

[0005] 2. The weight and volume of the water supply pump are large, which is not conducive to the miniaturization of the unit;

[0006] 3. The price of the water supply pump is high, which increases the design cost of the unit;

[0007] 4. The power of the water supply pump is relatively large, which increases the cost of the unit

However, the entire inner cavity of the traditional pressurized water storage tank does not have any separation. After the tap water enters the inner cavity of the water storage tank at the water inlet at the bottom of the water storage tank, the cold water and hot water are mixed rapidly in a large area on the cross-section of the entire inner cavity of the water tank. , causing the temperature of hot water to drop rapidly, so that it cannot be used, and the utilization rate of hot water is very low

To ensure the amount of hot water used, the volume of the water tank needs to be made large, resulting in increased costs, increased installation space, and increased heat preservation energy consumption of the water tank
