Air purified phase change heat accumulation type electric heater

Abstract

The invention discloses an air purified phase change heat accumulation type electric heater. The electric heater comprises a heat-insulating shell made from a heat-insulating material, wherein a containing cavity is formed in the heat-insulating shell, a heat accumulation container is arranged in the containing cavity, a phase change material, an electric heater and at least one heat tube heat exchanger are arranged in the heat accumulation container, a cold air inlet is formed in the top of the heat-insulating shell, a draft fan for introducing outside cold air into the containing cavity is arranged at the cold air inlet, a hollow filter element is covered below the cold air inlet, at least one hot air outlet for guiding hot air in the containing cavity out is formed in the side wall of the heat-insulating shell, the hot air outlet is positioned above the top of the heat accumulation container, a switching control panel for controlling the electric heater and the draft fan is arranged on the heat-insulating shell, the phase change temperature of the phase change material is at 80-300 DEG C, the heat accumulation density is large, the volume is small, the appearance is beautiful, the heat accumulation temperature is low, and the air purified phase change heat accumulation type electric heater is safe and reliable, and simultaneously can be used for purifying indoor air.

Description

technical field [0001] The invention relates to an air-purifying phase-change heat-storage electric heater, in particular to a phase-change heat-storage electric heater with the functions of air purification and heating. Background technique [0002] Heating in winter is a problem that must be solved in people's lives, and heating mainly includes multiple methods such as steam heat, water heat and electric heat. Electric heating is widely accepted due to its advantages of safety, environmental protection, flexible adjustment and convenient use. At present, electric heaters on the market mainly include electric oil heaters, heat pipe electric heaters, convection electric heaters, halogen tube electric heaters and far-infrared electric heaters. [0003] As China's economy has entered another accelerated growth, the contradiction between energy supply and demand has become increasingly prominent, and the power supply in cities is the most obvious. The power supply is insuffici...

Problems solved by technology

[0005] However, there are not many types of heat storage electric heaters commercialized on the market, mainly using sensible heat storage, the heat storage medium has small heat capacity, large volume and weight, large power consumption, and high heat storage temperature (up to 700 ℃), there is a risk of burns, low safety, and high prices, resulting in only a small market share of thermal storage electric heaters
