Heat pump type electric water boiler with purifying and sterilizing functions

Abstract

The invention discloses a heat pump type electric water boiler with purifying and sterilizing functions, and belongs to the technical fields of air source heat pumps and electric heaters. The heat pump type electric water boiler comprises a boiler body and a base with a base cavity, wherein the boiler body comprises an electric heating boiling water tank, an electric heating element and a hot water tap; the lower part of the electric heating boiling water tank is provided with a heat pump type water tank cavity separated by a bottom plate of the boiler body; the inside of the heat pump type water tank cavity is provided with a heat pump type water tank and a purifying and sterilizing mechanism; the purifying and sterilizing mechanism is connected in series between a water source pipe and a water inlet pipe of the heat pump type water tank, and is fixed with the bottom plate; a water outlet pipe of the heat pump type water tank is communicated with the electric heating boiling water tank; and the inside of the base cavity is provided with a heat pump heating mechanism used for heating water in the heat pump type water tank cavity of the heat pump type water tank. The technical scheme not only can save energy, reduce network load and prolong the service life of the electric heating element, but also can guarantee the cleanness of water.

Description

technical field [0001] The invention belongs to the technical field of air source heat pumps and electric heaters, and in particular relates to a heat pump type electric water boiler with purification and sterilization functions. Background technique [0002] In office spaces, public places (such as station waiting rooms, airport waiting rooms, etc.), hotels, restaurants, restaurants, industrial and mining enterprises, tea bars, drink bars, canteens and even homes, electric water heaters are widely used and are patented in China. There is no lack of technical solutions for electric water boilers in the literature, such as the electric water boiler recommended by the utility model patent authorization announcement number CN201034372Y and the purification water heater disclosed by CN201034373Y. The previous patent solved the siphon phenomenon, that is, avoided The backflow problem of the heated water caused by the negative pressure caused by the negative pressure caused by the...

Problems solved by technology

However, these two patented technical solutions are restricted by the high temperature characteristics of the heat pump. As the temperature of the water in the water tank rises, the heating efficiency of the heat pump, that is, the heat pump coefficient, will obviously decrease, so it is not enough to reflect the energy saving effect that people expect.

More specifically, when the temperature of the water in the water tank rises to about 60°C, due to the constraints of the refrigerant working fluid and the condenser, it is difficult or even impossible to continue to increase the water temperature, so the obtained hot water cannot be used for drinking. water, but only for washing or cooking
