Air energy water heater with defrosting and scale removing functions

Abstract

The invention provides an air energy water heater with defrosting and scale removing functions. The air energy water heater comprises a compressor and a water tank. The top of the water tank is detachably connected with a tank cover. A long-strip-shaped scraper located between a heat exchange coiled pipe and the inner side wall of the water tank is vertically arranged in the water tank. The two lateral sides of the scraper are close to the outer side wall of the heat exchange coiled pipe and the inner side wall of the water tank correspondingly. The top of the scraper is connected with a sleeve. The outer side of the upper portion of the sleeve is sleeved with a driven gear. The driven gear is engaged with a driving gear. A stepping motor is arranged on the outer side of the water tank. A medium circulation pipeline penetrates the interior of the sleeve and penetrates the tank cover to be connected with the heat exchange coiled pipe. An ultrasonic transducer is arranged on the side of an evaporator and connected with an ultrasonic generator. The air energy water heater has the beneficial effects that operation is simple, the removal cost is low, water scale on the heat exchange coiled pipe can be removed in time, and reduction of the heat exchange efficiency and increase of the energy consumption are avoided. Defrosting is conducted through power ultrasound, the defrosting effect and the frosting restraining effect are improved, and the energy consumption for defrosting is lowered.

Description

technical field [0001] The invention relates to an air energy water heater with the function of defrosting and cleaning dirt. Background technique [0002] An air source water heater, also known as an "air source heat pump water heater", is a device that uses the working principle of a heat pump to absorb heat from the air to produce hot water. The air-energy water heater transfers the heat in the environment to the water by allowing the refrigerant to continuously complete the thermodynamic cycle of evaporation, compression, condensation, throttling, and re-evaporation. The power consumption of air-energy water heaters is usually only a quarter of that of electric water heaters, and it does not need to rely on sunlight for heating like solar water heaters. Since the work of air-energy water heaters is realized through heat exchange with refrigerants, electric heating elements are not required. In contact with water, there will be no potential safety hazards such as electri...

Problems solved by technology

When the air conditioner is heating in winter, the compressor stops indoor heating during the heating and defrosting stage, causing the temperature to drop and affecting indoor comfort; while the air cooler and refrigerator are heating and defrosting, the stored items are affected by repeated temperature fluctuations, resulting in to store a decline in quality
