Embodiment 1

[0020] Embodiment 1: see figure 1 , the dry filter 1 for the refrigerator of the present invention comprises a filter shell 1.1 with two parallel air inlets 1.7 and 1.6, a built-in desiccant 1.2, and the gas outlet end section is closed into a thin tube section, and a one-way valve nozzle 1.3 ( The air outlet end of the valve nozzle is in the same direction as the air outlet of the filter) and the plugging rubber spool 1.4, and the outer limit ring 1.5 of the plugging spool.

[0021] In addition, the valve nozzle, the valve core and the limit structure can also be arranged on the inlet end of the filter, and can be set as one-way opening according to the working flow direction of the refrigerant gas.

[0022] It is also possible to set a one-way valve at both ends of the filter at the same time, and make the conduction and cut-off in the same direction; a spring can also be added between the spool and the spool limit (outside of the spool top opening) to improve the cut-off se...

Embodiment 2

[0023] Example 2: see figure 2 , the energy-saving refrigeration circuit of the refrigerator, including a compressor 2, the outlet end is connected to the air intake end of the drier filter 1 with a check valve in embodiment 1, and the outlet end of the drier filter 1 is connected in series with the working condenser 3.1, and connected to the two The three-way solenoid valve 4 is connected to form a pressure-maintaining circuit; the other inlet end of the dry filter 1 (which can also be connected to the compressor outlet) is connected in series with the auxiliary condenser 3.2, and then connected to the two-position three-way solenoid valve 4 to form a Stop the pressure relief circuit. The pressure-holding circuit and the pressure-relieving circuit are connected in parallel and in series to the inlet end of the capillary 5, are connected in series to the evaporator 6, and return to the compressor 2 to form a refrigeration circuit.

[0024] The compressor 2 is working, the hi...

Embodiment 3

[0025] Embodiment 3: see image 3 , As in embodiment 2, wherein the two-position three-way solenoid valve 4 is replaced by two stop valves 7,8. A dry filter 1 with a check valve, a working condenser 3.1, and a stop valve 7 are connected in series to form a pressure maintaining circuit; an auxiliary condenser 3.2 connected to the output end of the compressor, and a stop valve 8 are connected in series to form a shutdown pressure relief circuit. After the pressure holding circuit and the pressure relief circuit are connected in parallel, they are connected in series to the refrigeration circuit, and the working process is the same as that in Embodiment 2.

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 [0001] The invention relates to a dry filter for a refrigerator and an energy-saving refrigeration circuit. Background technique [0002] In order to make the refrigerator more energy-efficient, people have proposed an energy-saving refrigeration circuit technical scheme, which constitutes a pressure-holding circuit by setting a one-way valve in the refrigeration working circuit of the refrigerator, and a pressure-relief circuit is provided between the high-pressure output end of the compressor and the capillary, such as Chinese patent CN1395075 , CN1515851, CN2864515, CN2548089, etc., so that after the compressor stops working, under the cut-off of the one-way valve, the refrigerant in the condenser still maintains a relatively high pressure, so that when the compressor starts again, there is no need to pressurize It can immediately switch to the cooling condition, thereby reducing the useless work done by the compressor to start up the system again, reducin...
