A Feng-shaped unbalanced fin electric heating plate and a heating and humidifying device

Abstract

The invention provides an electric heating plate with unbalanced fins shaped like a Chinese character 'feng'. The electric heating plate with the unbalanced fins shaped like the Chinese character 'feng' comprises a substrate, wherein S-shaped electric heating tubes are cast in the substrate, air heating fins and evaporation fins are cast on the two sides of the substrate respectively, a separating plate is arranged at the front end of the substrate in an extension mode, and is used for isolation between a main ventilation area and a water mist evaporation area, evaporation baffles are arranged on the left side and the right side of the evaporation fins respectively, and the evaporation fins are thin and high. The invention further provides a heating and humidification device. The heating and humidification device comprises a heat-insulating shell, wherein an air suction inlet and an exhaust outlet are formed in the two ends of the heat-insulating shell respectively, and centrifugal fans, nozzles, the electric heating plate with the unbalanced fins shaped like the Chinese character 'feng' and a gas-and-steam mixing area are arranged in sequence from the air suction inlet. According to the electric heating plate with the unbalanced fins shaped like the Chinese character 'feng' and the heating and humidification device, the mode that operation of heating drying and operation of water supply vaporization humidification are independently carried out or are carried out in parallel is achieved, and the effects that the main ventilation area is free of water scale and the water mist evaporation area is descaled in a thermal shock mode are ensured.

Description

Technical field [0001] The invention relates to the technical field of designing electric heating plates, and in particular to a plumb-shaped unbalanced fin type electric heating plate and a heating and humidifying device. Background technique [0002] In order to warm up the air without drying in our activity space in winter, people invented a variety of heating and humidifying devices. E.g: [0003] Ultrasonic humidifier, the liquid water is oscillated at high frequency through ultrasonic waves to generate a large number of fine water mist particles, which are sprayed into the air; [0004] Steam generator, which heats liquid water into steam and injects it into the air; [0005] The high-enthalpy bath bath adopts a parallel heating method of temperature and humidity in the bathroom, ventilates and sprays water on the metal heating element with heat dissipation fins, which not only heats up the air, but also adds steam and humidifies the air. [0006] But while we enjoy the warmth a...

Problems solved by technology

[0008] ②After the steam generator runs for a long time, a large amount of scale will accumulate on the inner shell of the water tank, the surface of the electric heating tube, and the steam outlet. These scales will continue to accumulate and increase, which will affect the heat transfer of the electric heating tube; When the residual water flows into the sewer, it often causes poor drainage or even blockage

[0009] ③High-enthalpy Yubao, ventilation and spraying water on the metal heating element with cooling fins, not only heating the air, but also adding steam and humidifying the air; after long-term operation, scale will accumulate on the cooling fins of the metal heating element, Although scale can be eliminated by rapid "heating-cooling-heating-cooling" thermal shock method, it cannot be completely removed, thereby reducing the evaporation efficiency of water mist, especially the heat release capacity of ventilation
