Abstract

The utility model relates to a multifunctional maintenance box for a refrigerator, which is composed of a maintenance box body, a control plate, a face plate, a compressor, an air storage chamber, a vaporizing chamber, an auxiliary switching device of the vaporizing chamber, and pipelines. The compressor, the air storage chamber and the vaporizing chamber are communicated by the pipelines; the utility model has simple structure, and integrates multiple functions, such as pressurizing, vacuum pumping, welding, cleaning pipeline, etc., into one body, so the facilities used in repairing a refrigerator, such as a nitrogen cylinder, an oxygen cylinder, an acetylene (or liquid gas) cylinder, etc. can be exempted. The utility model has the advantages of small volume, light weight and portability, and the multifunction maintenance box for a refrigerator is suitable for being used in traveling in wide towns and countries.

Description

The multi-functional service kit of refrigerator

The utility model relates to the multi-functional service kit of a kind of refrigerator.

CN2096030U discloses a kind of portable refrigerator normalization maintenance of equipment, this equipment by pressurising, weld, vacuumize, annotate fluorine, electric-examination, tools section and two carrying cases and form, this maintenance of equipment is easy to carry, but each equipment is placed separately in the case, rely on the nitrogen cylinder pressurising, the cost height.

The purpose of this utility model provides a kind of simple in structure, pressurising, vacuumize, the multi-functional service kit of refrigerator that welding, detergent line are integrated.

For achieving the above object, the technical solution of the utility model is such, place compressor, air storage chamber and vaporizer in the multi-functional service kit of refrigerator, device for drying and filtering and low tension switch are arranged in the middle of compressor low pressure air suction (the promptly vacuumizing) pipeline, Pressure gauge and high-voltage switch gear are arranged in the middle of compressor and the air storage chamber pipeline connection, pipeline; The overpressure protection switch is arranged at the air storage chamber top; In the middle of air storage chamber and the vaporizer pipeline connection, pipeline the welding switch is arranged, the vaporizer high-pressure pipe is stretched nearly bottom of vaporizing chamber, and the gaseous mixture escape pipe only stretches into vaporizer slightly, and filling conduit and fuel door are arranged at the vaporizer top; Above-mentioned low tension switch, Pressure gauge, high-voltage switch gear, welding switch, fuel door and control power of compressor line, power supply indicator, power switch are installed on the control panel in service kit front; There is panel the control panel outside, and spare and accessory parts such as the switch on the protection control panel, electric wire suffer damage; Open panel, the panel reverse side hangs with a U type warming plate, and handle is arranged at the service kit top, and wheel is arranged at the bottom.

Adopt above-mentioned technology, air storage chamber can replace nitrogen cylinder and oxygen cylinder simultaneously, and vaporizer can replace acetylene cylinder or liquefied gas cylinder, greatly reduces maintenance cost, and the service kit volume is littler, lighter, is convenient to be adapted at vast town and country mobile operational process.The utility model also can keep in repair other refrigeration plants such as air-conditioning except the maintenance refrigerator.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the embodiment principle schematic.

Fig. 2 is an embodiment front control panel schematic diagram.

Fig. 3 is the embodiment schematic top plan view.

The working procedure of refrigerator maintenance shown in Figure 1 is as follows.One, pipeline cleans: close high-voltage switch gear 6 and welding switch 9; open compressor 4, toward air storage chamber 8 input airs, Pressure gauge 5 shows increased pressure gradually; overpressure protection switch 13 is arranged at air storage chamber 8 tops; when the pressure in the air storage chamber 8 surpasses 2MPa, can the automatic vent step-down, compressor 4 is shut down; open high-voltage switch gear 6; by high pressure gas interface 7 and process duct, blow toward waiting to repair in the refrigerator pipeline, utilize each pipeline of high pressure draught purge and capillaceous dirty stifled or ice is stifled.Two, pipeline leak detection: by process duct and high pressure gas interface 7, will wait to repair refrigerator and service kit and be communicated with, and close welding switch 9, and open high-voltage switch gear 6, and open compressor 4, and when reaching required pressure, can close maintenance system, and hunt leak, and find leakage point.Three, welding: the place to be welded of weldment is put in U type insulation iron plate, and U type insulation iron plate both can have been reduced heat and scattered and disappeared, and can preventing again burns waits to repair circuit and other flammable parts of refrigerator; Open fuel door 14, add an amount of gasoline 18, tighten fuel door 14, open low tension switch 2, close high-voltage switch gear 6 and welding switch 9, open compressor 4, when Pressure gauge 5 indication 0.3MPa pressure, open welding switch 9, high-voltage high-speed airflow makes gasoline 18 vaporization in the vaporizer 10 by high-pressure pipe 24 and mixes with the air of capacity, and gaseous mixture is delivered to welding gun 11 along gaseous mixture escape pipe 25, lights at the welding gun muzzle, temperature can reach more than 1500 ℃, carries out the welding of copper, iron, aluminium in U type insulation iron plate 12.Four, postwelding leak detection: the same with leak detection operating procedure before the weldering of second step.Five, vacuumize the injection cold-producing medium: connect the refrigerator of postwelding leak detection with process duct, triple valve, one on Pressure gauge, one connects low pressure air suction interface 1, open low tension switch 2 and high-voltage switch gear 6, close welding switch 9, open compressor 4, vacuumize, when vacuum reaches suitable numerical value, close maintenance system, pour into cold-producing medium then, seal.

Shown in Figure 2, open panel 19, hang with U type warming plate 12 on panel 19 reverse side, power line 15 is installed, Pressure gauge 5, power supply indicator 16 on the control panel 23, power switch 17, fuel door 14, welding gun 11, low tension switch 2, low pressure air suction interface 1, high-voltage switch gear 6, high pressure gas interface 7, welding switch 9, they are respectively by pipeline or circuit and safeguard the compressor 4 of case inside, air storage chamber 8, vaporizer 10 UNICOMs or connection.Handle 21 is arranged at the service kit top, and four wheels 22 is arranged at the bottom.

Shown in Figure 3, be compressor 4 from left to right, air storage chamber 8, vaporizer 10, device for drying and filtering 3 and overpressure protection switch be in control panel 23 the insides, low tension switch 2, Pressure gauge 5, high-voltage switch gear 6, welding switch 9, fuel door 14 is installed in respectively on the control panel 23.
