Heat-pump water heater and water tank assembly thereof

Abstract

The invention relates to a heat-pump water heater and a water tank assembly thereof. The heat-pump water heater comprises an inner container; the inner container comprises a barrel body, an upper endsocket and a lower end socket; the upper end socket is connected to the upper end of the barrel body, and the lower end socket is connected to the lower end of the barrel body; and the barrel body iscylindrical, and the ratio of the internal diameter of the barrel body to the internal height of the inner container and / or the ratio of the external diameter of the barrel body to the external heightof the inner container is 1:5-7, preferably, the ratio is 1:5.5-6.5. According to the heat-pump water heater and the water tank assembly thereof, the internal diameter of the barrel body is small, the ratio of the internal diameter to the internal height of the inner container is proper, the occupied area is small when the heat-pump water heater is installed, and installation is easy; besides, due to the small internal diameter of the barrel body, hot water can flow out of a water outlet in time, the hot water output rate is increased, a heating device is prevented from repeatedly heating hotwater, the cold water heating effect is improved, energy consumption of the heat-pump water heater is reduced, and the heating effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of hot water equipment, in particular to a heat pump water heater and a water tank assembly thereof. Background technique [0002] With the improvement of people's living standards, heat pump water heaters have also entered more and more families. A heat pump water heater generally has an inner tank and a heating device arranged in the inner tank. The inner tank is provided with a water inlet and a water outlet. Cold water enters from the water inlet, is heated by the heating device, and hot water flows out from the water outlet. Heat pump water heaters on the market have a relatively large inner diameter. On the one hand, this type of heat pump water heater occupies a large area and is not easy to install; on the other hand, it weakens the heating effect of the heating device. The treated hot water cannot flow out of the water outlet in time, causing the heating device to reheat the hot water, slowing down...

AI Technical Summary

Problems solved by technology

Heat pump water heaters on the market have a relatively large inner diameter. On the one hand, this type of heat pump water heater occupies a large area and is not easy to install; on the other hand, it weakens the heating effect of the heating device. The treated hot water cannot flow out of the water outlet in time, causing the heating device to reheat the hot water, slowing down the heating effect of the cold water, increasing the energy consumption of the heat pump water heater, and reducing the hot water output rate
