Abstract

The utility model discloses a domestic refrigerator which is mainly composed of a machine head and a box body, wherein, a compressor, an evaporation coil, a condenser, an electric fan, an evaporator, a filter and a capillary pipe are arranged in the machine head, and an air-conditioning electromagnetic valve, a machine head air-out pipe and a machine head air-return pipe are connected to the machine head in parallel; an air-out pipe and an air-return pipe are also arranged in the box body and are correspondingly connected with the machine head air-out pipe and the machine head air-return pipe. A selective switch for controlling the on-off of the air-conditioning electromagnetic valve is arranged in the machine head. The utility model has novel structure and convenient maintenance, and can be used as a low power air-conditioning.

Description

The novel dual-purpose refrigerator

The utility model belongs to a kind of household electric refrigerator.

There is not easy-maintaining in existing refrigerator, problems such as mobile inconvenience to the user.Refrigerator breaks down, and makes house calls and repairs seldom, and especially interior leakage and maintenance compressor etc. must be delivered to refrigerator special repair department to repair, and waste time and energy.For leakage problem in protected type condenser and the embedded evaporator, also need cut the cabinet insulation layer open, find interior leak source, the heat-insulation layer after so repairing can't recover original heat-insulating property, and the cold draining power consumption increases.Also destroyed the good looking appearance of refrigerator.In addition, in refrigerator uses owing to consider heat dissipation problem, to keep at least between about refrigerator and back and the body of wall 10cm above between square be used for heat radiation, the refrigerator floor space is increased.

The purpose of this utility model provides a kind of carrying maintenance of being convenient to, and reduces floor space, and has the refrigerator of air conditioning function.

The utility model is design like this: a kind of novel dual-purpose refrigerator is made up of casing, compressor, evaporation coil, capillary, temperature controller, condenser, electric fan, defrosting heater liquid reservoir, filter etc., its main feature is: compressor, evaporation coil, capillary, condenser, electric fan, defrosting heater, frost removal timer etc. are installed concentratedly in a head, head is installed on the casing, and head and casing can be disconnected from each other, and be independent separately.Head is separated into mutually airtight two parts, and compressor, evaporation coil, capillary, condenser, temperature controller are set in the part, and on one section capillary an air-conditioning magnetic valve in parallel, the corresponding selector switch that is provided with.Be provided with fan, discharge pipe, backwind tube, evaporimeter, defrosting heater and drip tray heater in another part, establish an outlet pipe on this two-part interlayer.Casing is provided with discharge pipe and backwind tube and corresponding with it adjustable go out air door and adjustable return air door, and the discharge pipe and the corresponding connection of backwind tube of the discharge pipe of casing and backwind tube and head.

The utility model is simple in structure, and is easy to use, is convenient to maintenance, offers convenience to the consumer.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is the utility model handpiece structure schematic diagrames.

Accompanying drawing 3 is the utility model body structure schematic diagrames.

Accompanying drawing 4 is the utility model head vertical views.

Indicate among the figure and be described as follows:

1, casing; 2, head; 3, condenser; 4, compressor; 5, starting relay; 6, capillary; 7, air-conditioning magnetic valve; 8, electric fan; 9, head discharge pipe; 10, evaporimeter; 11, defrosting heater; 12, drip tray; 13, drip tray heater; 14, head backwind tube; 15, evaporation coil; 16, radiator; 17, liquid reservoir; 18, filter; 19, selector switch; 20, temperature controller; 21, frost removal timer; 22, outlet pipe; 23, casing discharge pipe; 24, adjustablely go out air door; 25, return air inlet; 26, casing backwind tube; 27, adjustable return air door.

The utility model is work like this: when selector switch 19 is placed common state, the high-temperature high-pressure refrigerant overheated gas that is produced by compressor 4 is introduced into evaporation coil 15, after condenser 3 heat release condensations, enter filter 18, liquid reservoir 17 again, enter capillary 6 then, enter evaporimeter 10 subsequently and carry out heat exchange, at last, get back in the compressor 4 by the compressor return air pipe; The cold air that produces in the process is blown into casing 1 by electric fan 8 from head discharge pipe 9 and casing discharge pipe 23, carries out being sucked by casing backwind tube 26 and head backwind tube 14 after the heat exchange, forms circularly cooling.Regulate that adjustable in the casing goes out air door 24 and adjustable return air door 27 is controlled the air conditioning quantity that enters casing 1.Regularly the frost that produces is heated defrost with frost removal timer 21 and temperature controller and defrosting heater 11, the water part that defrost produces is with 13 evaporations of drip tray heater, and another part flows out by outlet pipe 22, utilizes evaporation coil 15 heat heating evaporations.

Close when placing the air-conditioning state when selection being opened 19, air-conditioning magnetic valve 7 is connected, and refrigerant is by filter 18, and liquid reservoir 17 enters capillary 6; Because the conducting of air-conditioning magnetic valve 7 makes one section short circuit of capillary 6, the stroke of refrigerant in capillary shortens, and evaporating pressure is improved, and increases refrigerating capacity, by the regulating action of liquid reservoir, whole head can be used as minitype air conditioner separately.

Claims
