Description

Technical Field

[0001] This utility model relates to the technical field of air intake pipe assembly, and more specifically to an air intake pipe assembly for a refrigerator. Background Technology

[0002] In the refrigeration system of a refrigerator, the suction pipe assembly is a key component, which undertakes the important task of connecting the evaporator and the compressor and transporting low-temperature and low-pressure gaseous refrigerant. Its performance directly affects the refrigerator's refrigeration efficiency, energy consumption level and operational stability. During use, the refrigerator's suction pipe assembly requires the addition of refrigerant for cooling. If refrigerant leaks during use, the cooling effect of the refrigeration equipment may decrease after 3-5 years of use, and the operator may not notice it in time, thus affecting the operator's user experience. If the evaporator of a refrigerator's suction pipe assembly malfunctions or breaks during use, liquid may accumulate in the pipes inside the evaporator. This liquid accumulation can cause a short circuit in the internal circuitry of the device, posing a safety hazard. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a refrigerator air intake pipe assembly to solve the problems existing in the background art.

[0004] This utility model provides the following technical solution: a refrigerator suction pipe assembly, including a compressor, a temperature measuring device fixedly connected to the outside of the compressor, a return pipe movably sleeved inside the temperature measuring device, a temperature measuring coil fixedly sleeved inside the return pipe, a junction box fixedly connected to the outside of the temperature measuring coil, a cable fixedly connected to the outside of the junction box, and an indicator light fixedly connected to the outside of the cable.

[0005] Furthermore, the compressor is externally fixedly connected to a process pipeline, and the compressor is externally fixedly connected to an outlet pipe.

[0006] Furthermore, a condenser is fixedly connected to the outside of the outlet pipe, and a heat dissipation device is provided on the top of the condenser.

[0007] Furthermore, a dustproof net is fixedly connected to the bottom of the heat dissipation device, a radiator mounting block is fixedly connected to the outside of the condenser, and a radiator bracket is movably connected to the outside of the radiator mounting block.

[0008] Furthermore, the outlet pipe is externally connected to a drying filter, and the drying filter is externally fixedly connected to an anti-slip texture.

[0009] Furthermore, the externally movably connected capillary tube of the dryer filter is externally movably connected to the evaporator.

[0010] Furthermore, a positive conductive plate is fixedly connected to the bottom of the evaporator, a negative conductive plate is fixedly connected to the inner wall of the evaporator, and a dust cover is movably connected to the top of the evaporator.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model uses a temperature measuring coil installed inside the temperature measuring device to detect the temperature of the return gas pipe and transmits the detection data to the junction box for analysis. When the temperature overflows, it proves that the evaporation is insufficient, the return gas is overheated, and the cooling effect is significantly reduced. This reminds the operator to check whether there is a refrigerant leak, which leads to a decrease in the cooling effect, and to add an appropriate amount of refrigerant.

[0012] 2. This utility model utilizes positive and negative conductive plates installed inside the evaporator to form a conductive circuit through the liquid accumulation in the internal pipes. When the liquid accumulation in the evaporator exceeds a set threshold, the liquid simultaneously contacts the positive and negative conductive plates, connecting the circuit and sending an electrical signal to the designated device, thus reminding the operator to clean it in time in the form of an audible and visual alarm.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The refrigerator suction pipe assembly involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1-4 This utility model provides a refrigerator suction pipe assembly, including a compressor 1, a temperature measuring device 2 fixedly connected to the outside of the compressor 1, a return pipe 3 movably sleeved inside the temperature measuring device 2, a temperature measuring coil 4 fixedly sleeved inside the return pipe 3, a junction box 5 fixedly connected to the outside of the temperature measuring coil 4, a cable 6 fixedly connected to the outside of the junction box 5, and an indicator light 7 fixedly connected to the outside of the cable 6. This facilitates the detection of the temperature of the return pipe 3 through the temperature measuring coil 4 installed inside the temperature measuring device 2, and transmits the detection data to the junction box 5 for analysis. When the temperature overflows, it indicates insufficient evaporation, overheating of the return gas, and a significant decrease in cooling effect, reminding the operator to check for refrigerant leakage, which leads to reduced cooling effect, and to add an appropriate amount of refrigerant.

[0020] In a preferred embodiment, the compressor 1 is externally fixedly connected to a process pipe 101 and an externally fixedly connected to an outlet pipe 102. This facilitates the transport of the high-temperature superheated steam compressed by the compressor 1 to the condenser 103 via the outlet pipe 102 installed externally. The process pipe 101 installed externally on the compressor 1 can also be used as a return pipe.

[0021] In a preferred embodiment, the condenser 103 is fixedly connected to the outside of the outlet pipe 102. The top of the condenser 103 is provided with a heat dissipation device 104, which facilitates the dissipation of the high-temperature and high-pressure steam inside the condenser 103 through the heat dissipation device 104, turning it into a high-pressure and medium-temperature liquid.

[0022] In a preferred embodiment, a dustproof net 105 is fixedly connected to the bottom of the heat dissipation device 104, a radiator mounting block 106 is fixedly connected to the outside of the condenser 103, and a radiator bracket 107 is movably connected to the outside of the radiator mounting block 106. This facilitates the prevention of dust from entering the heat dissipation device 104 and affecting the rotation of the internal fan by using the dustproof net 105 installed at the bottom of the heat dissipation device 104. Furthermore, the radiator mounting block 106 and the radiator bracket 107 are engaged with the outside of the heat dissipation device 104, thereby facilitating the operator to quickly disassemble the heat dissipation device 104 for maintenance and cleaning.

[0023] In a preferred embodiment, the outlet pipe 102 is externally connected to a dryer filter 108, and the dryer filter 108 is externally fixedly connected to an anti-slip texture 109. This facilitates the filtration of moisture and impurities by the dryer filter 108 installed on the outside of the outlet pipe 102, avoiding blockage of the subsequent capillary tube 110. The anti-slip texture 109 on the outside of the dryer filter 108 is also used to facilitate the operator to disassemble and clean the dryer filter 108.

[0024] In a preferred embodiment, the externally movably connected dryer filter 108 is a capillary tube 110, which is externally movably connected to the evaporator 201. This facilitates the flow of the filter to the evaporator 201 after being intercepted and depressurized by the capillary tube 110.

[0025] In a preferred embodiment, a positive conductive plate 202 is fixedly connected to the bottom of the evaporator 201, a negative conductive plate 203 is fixedly connected to the inner wall of the evaporator 201, and a dust cover 204 is movably connected to the top of the evaporator 201. This facilitates the formation of a conductive circuit by the positive conductive plate 202 and the negative conductive plate 203 installed inside the evaporator 201, using the liquid accumulated in the internal pipes. When the liquid accumulation inside the evaporator 201 exceeds a set threshold, the liquid simultaneously contacts the positive conductive plate 202 and the negative conductive plate 203, thus conducting the circuit and sending an electrical signal to the designated device, thereby reminding the operator to clean it in time in the form of an audible and visual alarm.

[0026] The working principle of this utility model is as follows: The refrigerator's suction pipe assembly detects the temperature of the return pipe through a temperature measuring coil installed inside the temperature measuring device, and transmits the detection data to the junction box for analysis. When the temperature overflows, it indicates that evaporation is insufficient, the return gas is overheated, and the cooling effect is significantly reduced. This reminds the operator to check whether there is a refrigerant leak, which leads to a decrease in cooling effect. Add an appropriate amount of refrigerant. The exhaust pipe installed on the outside of the compressor transports the high-temperature superheated vapor compressed by the compressor to the condenser. The compressor also has a process pipe installed on its outside that can be used as a return pipe. The heat dissipation device dissipates the high-temperature and high-pressure vapor inside the condenser, turning it into a high-pressure, medium-temperature liquid.

[0027] A dustproof screen installed at the bottom of the heat dissipation device prevents dust from entering the device and affecting the rotation of the internal fan. The heat dissipation device is externally fixed with a radiator mounting block that engages with the radiator bracket, allowing operators to quickly disassemble the device for maintenance and cleaning. A dryer filter installed on the outside of the outlet pipe filters out moisture and impurities to prevent blockage of the subsequent capillary tube. The dryer filter has anti-slip textures on its outside for easy disassembly and cleaning. After being intercepted and depressurized by the capillary tube, the air is delivered to the evaporator.

[0028] The positive and negative conductive plates installed inside the evaporator form a conductive circuit by accumulating liquid in the internal pipes. When the liquid accumulation in the evaporator exceeds a set threshold, the liquid simultaneously contacts the positive and negative conductive plates, connecting the circuit and sending an electrical signal to the designated device, thus reminding the operator to clean it in time in the form of an audible and visual alarm.
