Description
Technical field
The present invention relates to a kind of air-source water heater with defrosting snaking function.
Background technology
Air-source water heater, it is that heat is absorbed from air with heat pump operation principle also referred to as " air source hot pump water heater "
Measure to manufacture the device of hot water.Air-source water heater evaporates, compresses, condenses, throttles and steamed again by allowing refrigerant constantly to complete
The thermodynamic cycle process of hair, the heat in environment is transferred in water.The power consumption of air-source water heater generally only has electric hot water
The a quarter of device, and sunlight need not be relied on as solar water heater and adopt heat, due to the work of air-source water heater
It is to exchange heat to realize by refrigerant, therefore is contacted also without electrical heating elements with water, would not be also deposited as electric heater
In the potential safety hazard of electric leakage, dry combustion method, also without the danger that blast occurs and is poisoned, fool proof, while also very ring is used
Protect, general service life can reach 15 to 20 years.
The heat of thermal medium is transferred in water by air-source water heater by heat exchanger tube, and existing heat exchanger tube is a kind of to be external
Formula heat exchanger tube, i.e., heat exchanger tube is wrapped in the periphery of water tank to be heated to the water in water tank, this mode of heating heat exchange is not
Fully, the water firing rate in the middle part of water tank is slower, and the heat exchanger tube thermal loss for being placed in outside is larger, and energy consumption is also very high；It is another
Kind is built-in heat exchanger tube, duplex coil is built in water tank water is heated, duplex coil considerably increases heat-transfer surface
Product, heat transfer efficiency is high, and energy consumption is low, and the heat exchanger tube of this duplex coil is placed in water easy fouling for a long time, and because of duplex coil
The structure not incrustation scale outside easy cleaning heat exchanger tube, as incrustation scale increases in heat exchange pipe outer wall, the heat transfer effect of heat exchanger tube is also got over
It is poorer to come, and energy consumption also gradually increases.
Evaporator is a critical component of the refrigeration system based on air source heat pump structure, and heat pump air side is evaporated
The surface frosting of device can block fin clearance (air duct of evaporator), reduce the air mass flow between fin, increase evaporator
Thermal resistance, reduce the heat exchange efficiency of evaporator.
Evaporator is mainly removed using the Defrost method of heating defrosting, including the reverse hot gas defrosting of four-way valve and electrical heating at present
Frost, when deposited on evaporator it is white enough when, just open defrosting function.When air-conditioning heats in the winter time, heating defrost stage pressure
Contracting machine stops indoor heating, causes temperature to decline, influences indoor comfort degree；And air-cooler, refrigerator be when heating defrost, storage
Article brings the decline of storage quality because the recurrent fluctuations by temperature is influenceed.
The content of the invention
To solve technical deficiency above, the invention provides a kind of air energy thermal water with defrosting snaking function
Device, the incrustation scale on heat exchanger tube can be removed in time, improve heat exchange efficiency.
The present invention is achieved by the following measures：
A kind of air-source water heater with defrosting snaking function of the present invention, including compressor and water tank, the water tank

Separator, the tank top are removably connected with case lid, are vertically arranged with water tank positioned at heat exchange coil and water tank madial wall
Between strip scraper plate, heat exchange coil lateral wall and water tank madial wall, scraper plate are pressed close in two sides of the scraper plate respectively
Top the sleeve passed from case lid center is connected with by cross bar, the lower cartridge, which passes through sealed bearings and rotated with case lid, to be connected
Connect, driven gear is cased with the outside of upper cartridge, the driven gear is engaged with driving gear, driving is provided with the outside of the water tank
The stepper motor of driving gear is connected, the medium circulation pipeline is through in sleeve and is connected through case lid with heat exchange coil；
The evaporator side is provided with ultrasonic transducer, and the ultrasonic transducer is connected with supersonic generator, the ultrasound
Wave producer is connected with controller, and the controller is connected with frost thickness sensor and temperature sensor.
Above-mentioned water tank bottom is provided with the bottom of circular arc, and bottom is provided centrally with sewage draining exit, set at the sewage draining exit
There is blowoff valve.
Hairbrush is provided with two sides of above-mentioned scraper plate.
Some through holes are provided with above-mentioned scraper plate.
The beneficial effects of the invention are as follows：Heat exchanging coil surface it can be cleared up at any time, it is not necessary to dismantle water tank, operate
Simply, disposal costs are low, can dispose the incrustation scale on heat exchange coil in time, avoid the reduction of heat exchange efficiency and the increasing of energy consumption
Greatly.The present invention using power ultrasonic triggered by a narrow margin, high frequency, high acceleration mechanical oscillation defrosted, improve defrosting, suppress
The effect of frosting, and reduce the energy expenditure of defrosting, it is ensured that the safety of ultrasonic system.
