Description
Technical field
The present invention relates to the refrigerators of a kind of household electrical appliance, especially AC and DC.
Background technique
Currently, well known household electric refrigerator, is all to use AC power supply, dangerous, areas without electricity cannot be used, in order to save
Can be environmentally friendly, units concerned have walked the patent " not having to, use less, directly with system for family's dual track system power supply " for promoting me then
ZL201220245052.1 is now referred to as the DC voltage 220V " directly with formula photovoltaic power generation ", currently, there are no alternating current-direct currents in the market
Dual-purpose refrigerator develops AC and DC refrigerator, is the needs of development of the situation.Compressor of air conditioner on automobile is with starting
What machine drove, the compressor of air conditioner on automobile is small in size high-efficient, and is not afraid of vibration, if the compressor of air conditioner on automobile,
Dc motor power supply is supplied electricity to 220V photovoltaic DC, with dc motor come with the compressor on electrical automobile, but in test
It was found that the compressor of air conditioner on automobile drives compressor to be equipped with problem with alternating current generator, but when with direct current generator, because of motor function
Rate is big, and when switch is switched on and off motor power, switch wants arcing, I once with 30 amperes of alternating current toggle switch,
Because of arcing, first and second can only be used, switch contact is just blown or adhesion.In order to keep alternating current and photovoltaic DC electricity dual-purpose, look for
A kind of can be a new problem again with the dual-purpose motor of AC and DC.
Summary of the invention
When in order to overcome current automobile air conditioner compressor using powerful direct current generator, contact is burnt caused by switching because of arcing
It the problem of disconnected and adhesion, solves this problem with plug-in strip, in order to find universal motor, is sent out by multiple development test
Existing, in existing alternating current generator, it is permanent magnetism and excitation that rotor, which is coil, stator, when with 220V direct current, although also having
A part is available, but cumbersome, finally the single phase series motivated motor of determining alternating current, and single phase series motivated motor is AC and DC electricity
Motivation, watt level have, and sized fridge is suitble to select.
The technical solution adopted by the present invention to solve the technical problems is: it is by refrigerator basic device and AC and DC
Power device, ac-dc dual power supply conversion control device three parts composition.Refrigerator basic device, is compressed by air conditioning for automobiles
Machine, condenser, evaporator, liquid storage dryer, capillary and the most composition of defroster six.AC and DC power device, by
Single phase series motivated motor, belt pulley, belt, take-up pulley and on the compressor electromagnetic clutch composition.Ac-dc dual power supply turns
Control device is changed, is made of AC and DC output 12V Switching Power Supply, AC/DC motor conversion plug-in strip, direct current suppression arc plug-in strip.
Its process of refrigerastion working principle is: after AC-DC motor powers on, motor rotation, when the temperature of temperature controller is in setting temperature
Spend or more when, temperature controller is connected, and electromagnetic clutch is attracted, and compressor operating is compressed into refrigerating fluid the steam of high temperature and pressure, send
It to condenser, is blown out through fan, radiates in outside cabinet, the liquid of medium temperature high pressure is become low through liquid storage dryer and capillary
The liquid of warm low pressure is sent into evaporator in case, becomes the gas of medium temperature low pressure after heat absorption, returns to compressor, starts to follow for the second time
Ring.Ac-dc dual power supply conversion control device divides high pressure 220V and low pressure 12V two parts again, and the electromagnetic clutch on automobile is
The power supply of 12V DC electricity, for this purpose, fan of refrigerator, also uses 12V DC electricity to power at headlamp from security standpoint, develops and hand over
The output of DC dual-purpose is the power supply of 12V high current, also at a problem of alterating and direct current refrigerator, dissection exchange electricity output
The Switching Power Supply of 12V direct current, such as the power pack on desktop computer, it is by alternating current 220V current rectifying and wave filtering circuit, switch vibration
This several part of circuit, high-frequency impulse current rectifying and wave filtering circuit, sampling and controlling circuit of voltage regulation are swung to complete, and the of Switching Power Supply
One step is exactly 220V alternating current, and through filter rectification at direct current, and " straight with formula photovoltaic power generation " DC voltage is 220V, straight
Galvanic electricity be connected to Switching Power Supply it is rectified after output end on, according to it is demonstrated experimentally that requirement is fully achieved, in present specification
In, only illustrate that direct current is electrically accessed place, aft section is not illustrated, because this is well-known principle.
It is small in size high-efficient and be not afraid of vibration the invention has the advantages that using the compressor of air conditioner on automobile, with list
Phase series excited machine is used as power, and with photovoltaic direct current, will not beat arc, it is also possible to common alternating current, energy conservation but conveniently.
