Abstract
The invention relates to a drier-filter and an energy-saving refrigeration circuit of a refrigerator. The invention is characterized in that the air inlet and/or outlet end sections of the filter tube of the drier-filter are provided with a one-way valve inside, consisting of a valve nozzle, a blocking valve core and a valve core stop, and the one-way valve conducts along the flowing direction of the refrigerant. The drier-filter of the invention not only retains the original functions but also has the function of one-way valve, thus achieving double functions. By integrating the one-way valve and the drier-filter and taking the filter tube shell as the valve tube shell, the invention saves the one-way valve shell and the valve material. In addition, The drier-filter is used in the energy-saving cooling cycle circuit of refrigerator, and the one-way valve is built in the filter, omitting the welding of connecting the inlet and outlet of the one-way valve and the pipeline, thus not only omitting the extra welding procedure, but also reducing the possible leak points; therefore, the cooling work becomes more reliable and the maintenance is reduced.
Description
Technical field
The present invention relates to a kind of dry filter for refrigerator and energy-conserving refrigeration loop.
Background technology
For making refrigerator more energy-conservation; people propose the energy-conserving refrigeration loop technical scheme; by being set in refrigerator refrigeration work loop, check valve constitutes pressure dwelling loop; and between compressor output high-pressure side and capillary, depressurized circuit is set; as Chinese patent CN1395075; CN1515851; CN2864515; CN2548089 etc. are described; thereby after making that compressor quits work; in ending down of check valve; make the refrigerant that still keeps elevated pressures in the condenser; work as compressor like this and start once more, need not pressurising and can change the refrigeration operating mode immediately over to, start the idle work that system's pressurising is done once more thereby reduce compressor; reduce the loss of refrigerator startup-shutdown, reach energy-conservation.
Yet this refrigeration loop is pressurize need be connected in series check valve, the Chinese patent CN2607495 refrigerating system check valve of applicant application for example, increased the refrigerating circuit cost, and at condenser inlet end serial connection check valve, need be welded to connect separately, increase the coolant tubes pipeline connector, increased possible leakage point.Therefore, still have worth improved place.
And the current refrigerator device for drying and filtering is only had a simple function, promptly only plays impurity screening and absorbs the moisture content function, and do not have any other function, and this is the prior art situation.
Summary of the invention
The object of the invention is to overcome the deficiency of above-mentioned prior art, provides a kind of building block few, need not to weld separately, can make filter have the dry filter for refrigerator of non-return valve function simultaneously.
Another purpose of the present invention is to provide a kind of energy-saving refrigerator energy-saving refrigeration loop.
The present invention's first purpose realizes that main the improvement is in device for drying and filtering air inlet and/or outlet side section, is built-in with valve and chews and the shutoff spool, and the check valve of the spacing composition of spool, thereby make device for drying and filtering have non-return valve function simultaneously, realize dual-use material.Specifically, dry filter for refrigerator of the present invention comprises filter shell and built-in drier, it is characterized in that screen pipe air inlet and/or outlet side section, built-inly chew and shutoff spool, the spacing check valve of forming of spool check valve sincerely yours cryogen work flow direction conducting by valve.
Compressor output high pressure refrigerant gas, during by the dry filter pipe, under high cryogen pressures power, the seal spool spare that the shutoff valve is chewed lifts, and valve is chewed conducting, and refrigerant gas flows to the refrigerator refrigerating system, operate as normal by this valve; When compressor quits work, the reverse spool shutoff of air pressure valve is chewed and valve is end, make that the condenser after being cut off keeps high pressure conditions, like this when compressor startup work next time, can enter the refrigeration work state immediately, and not need to make earlier condenser to be charged to high pressure, help realizing that refrigeration is energy-conservation.
The said shutoff spool of the present invention can be the various forms spool of prior art refrigerator with valve.In addition, can also compression spring be set, further improve by the shutoff sealing in spool one side.Built-in check valve assembly better is to be arranged in the section of device for drying and filtering outlet side.
Spool is spacing, and main effect is that the restriction spool is gone out, and it can be can limit spool to go out arbitrarily and radially protrude, and scrobicular ring, projection are spacing etc. in for example on snap ring, the shell all can.
The present invention's second purpose realizes, the refrigerator energy-saving refrigeration loop, comprise the refrigeration work loop of forming by compressor, device for drying and filtering, condenser, capillary, evaporator series, the air inlet and/or the outlet side section that it is characterized in that device for drying and filtering in the refrigeration loop, built-inly chew and shutoff spool, the spacing check valve of forming of spool by valve, check valve sincerely yours cryogen work flow direction conducting, the condensator outlet end is serially connected with the unidirectional conducting valve of refrigeration; Compressor outlet and capillary entrance point are serially connected with auxiliary condenser, constitute to shut down depressurized circuit.
Depressurized circuit; identical with the effect of prior art depressurized circuit, principle; by the capillary release; can make output high pressure refrigerant off-load after the compressor shutdown; balance compressor import and export pressure helps next circulation starting of compressor, simultaneously under capillary resistance; compressor operating output high cryogen pressures can not be relaxed the short fast stream in loop, can guarantee cooling effect.Wherein a kind of better is that the serial connection compressor operating is the unidirectional conducting valve that ends in depressurized circuit, can fully high-pressure refrigerant be ended when compressor operating, guarantees high refrigeration.
The present invention is owing to adopt in device for drying and filtering air inlet and/or outlet side section, built-inly chew and shutoff spool, the spacing check valve of forming of spool (cryogen workflow wizard that sincerely yours is logical) structure by valve, make device for drying and filtering not only keep original function, but also has non-return valve function, can't hinder the device for drying and filtering operate as normal, realize a thing dual-purpose.Check valve and device for drying and filtering are combined into one, make the valve shell, also omitted the check valve shell, saved the valve material by the filter shell.In addition, be used for refrigerator energy-saving type refrigerant cycles loop, the built-in check valve of filter, also omitted the check valve import and export and be connected welding, not only omitted welding sequence separately, and reduced the leakage point that may cause with pipeline, make refrigeration work more reliable, maintenance capacity reduces.
Below in conjunction with several specific embodiment, further specify the present invention.
