Description

Technical Field

[0001] The present invention relates to the field of refrigerator application protection technology, and in particular to a multi-layer dynamic air-cooled refrigerator. Background Art

[0002] Air-cooled freezers mainly use fans to circulate cold air, so that the air inside the freezer keeps flowing, thereby taking away heat and achieving the purpose of lowering the temperature. After the evaporator absorbs heat, the cold air is sent to the freezer chamber through the air duct and outlet to achieve the refrigeration and freezing functions.

[0003] In order to distinguish the refrigeration and freezing effects, the existing air-cooled refrigerators mostly adopt a dual control system, that is, two evaporators or two condensers are set, such as an air-cooled vertical refrigerator disclosed by announcement number CN211060470U and a built-in double evaporator refrigerator disclosed by announcement number CN213657214U. The former condenser includes an external condenser and a built-in condenser. The external condenser is a fin-type air-cooled condenser, and the built-in condenser is a condensing coil. The built-in condenser is arranged between the rear side wall of the inner shell and the rear side wall of the outer shell. The compressor, the external condenser, the built-in condenser, the throttling element and the evaporator are connected end to end through pipelines to form a Refrigeration circuit, the latter connects the two evaporators through a connecting plate. When installing the evaporator, the two evaporators can be installed directly to enhance the air flow inside the cabinet and reduce the probability of temperature difference inside the cabinet. Although the above method improves the condensation and evaporation effects, it also increases the space pressure of the refrigerator and increases the energy consumption of the refrigerator. Moreover, there is more than just temperature difference between the refrigeration and freezing effects. If the transmitted low-temperature cold air is not distinguished, the differentiated refrigeration and cold delivery effect is achieved by simply increasing the number of refrigeration systems. It is difficult to clearly distinguish between the refrigeration and freezing functions, and it does not meet the market demand for energy saving and environmental protection. More importantly, the existing air-cooled refrigerators are designed to compress volume and weight, and mostly adopt an integrated structure, that is, the main components such as the evaporator, compressor and condenser are centrally arranged, such as a refrigerator disclosed by announcement number CN218672777U, which allows the condensed water to fully exchange heat with the back plate when flowing through the drain pipe. At this time, the back plate plays the role of a heat exchange fin, increasing the heating area of ​​the drain pipe. At the same time, since the drain pipe is arranged on the back plate and extends along its extension direction, the structure is relatively compact and does not occupy the structural space of the compressor compartment. However, the compressor and condenser will generate high-temperature heat during operation, and heat will also be released due to the state change of Freon-12. If only a single cooling fan is used to dissipate the high-temperature heat in the cabinet, it will not only be inefficient but also have little effect, so that the electrical components with the evaporator, compressor and condenser as the main body can only operate under load under high temperature and high pressure conditions, which can easily cause overload and short circuit accidents. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that it is difficult to carry out directional cooling and heat dissipation protection for air-cooled refrigerators, and to propose a multi-layer dynamic air-cooled refrigerator.

[0006] Preferably, the first thermostat is electrically connected to the first valve and the dehumidifier, the second thermostat is electrically connected to the second valve and the humidifier, and both the first thermostat and the second thermostat are electrically connected to the purifier.

[0007] Preferably, the heat dissipation part includes: A water-cooling box frame, which is arranged in the extension chassis corresponding to the compressor and the condenser; An air-cooling pipeline, which is arranged in the extension chassis corresponding to the capillary tube; An air intake window, which is opened at the rear end of the cabinet corresponding to the extension chassis, and the air intake window is flush with the air-cooling pipeline; An air outlet window, which is opened at the rear end of the cabinet corresponding to the extension chassis, and the air outlet window is flush with the water-cooling box frame.

[0009] Preferably, the air-cooling pipeline includes: A pressure-reducing pipe fitting, which is used to fixedly sleeve the capillary tube; A cold air inlet pipe, which is fixedly connected to the upper end of the pressure-reducing pipe fitting, and the cold air inlet pipe extends outside the cabinet through the air intake window, and an air inlet with an S-shaped cross-section structure is arranged in the cold air inlet pipe; A cold air exhaust pipe, which is fixedly connected to the lower end of the pressure-reducing pipe fitting, and the cold air exhaust pipe corresponds to the heat dissipation pipe group.

[0010] Preferably, the pressure-reducing pipe fitting includes: An upper thick-diameter port, which is fixedly connected to the cold air inlet pipe; A middle thin-diameter short pipe, which is integrally connected to the upper thick-diameter port; A lower thick-diameter port, which is integrally connected to the middle thin-diameter short pipe.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The present invention sets an evaporator at the top of the cabinet body, and sets a compressor, a condenser and a capillary tube at the rear end of the cabinet body to form a refrigeration mechanism that generates a refrigeration effect through electric energy, clearly dividing the high-temperature and low-temperature areas in the cabinet body, so as to reduce the influence of the high-temperature heat generated by the compressor, condenser and capillary tube during operation on the evaporator, thereby making full use of the low-temperature effect of the evaporator, and at the same time facilitating heat dissipation protection for the compressor and condenser in the high-temperature area.

[0012] 2. The present invention sets a first transmission pipeline connecting the evaporation box and the refrigerating chamber and a second transmission pipeline connecting the evaporation box and the freezing chamber in the cabinet body, so that only one evaporator needs to be set to provide a low-temperature effect for the refrigerating chamber and the freezing chamber. At the same time, by setting an air supply part composed of a thermostat, a valve, a dehumidifier, a humidifier and a purifier, it is convenient to independently transport low-temperature cold air according to the temperature conditions of the refrigerating chamber and the freezing chamber, and to control the drying and humidification of the low-temperature cold air to ensure that different degrees of refrigeration effects are formed by providing differential low-temperature cold air for the refrigerating chamber and the freezing chamber.

[0013] 3. The present invention sets a water-cooled box frame composed of an aluminum foil hollow board, a U-shaped hollow board and a heat dissipation pipe group in the cabinet body to cool the compressor and condenser by cold compress, and uses a powerful suction pump to realize the recycling of the coolant, so that the heated coolant returns in multiple forms to reduce the high-temperature pressure of the cold cabinet body.

[0014] 4. The present invention sets an air-cooled pipeline composed of a pressure-reducing pipe fitting, a cold air inlet pipe and a cold air exhaust pipe in the cabinet body, and uses an upper thick-diameter port, a middle thin-diameter short pipe and a lower thick-diameter port to form a pressure-reducing pipe fitting for sleeving the capillary tube. Because the capillary tube transports high-temperature and high-pressure liquid Freon-12, the inside of the pressure-reducing pipe fitting is in a high-temperature and low-pressure state, and the cold air inlet pipe is used to quickly inhale normal-temperature gas. Also, due to the change in the caliber sizes of the upper thick-diameter port, the middle thin-diameter short pipe and the lower thick-diameter port, the circulation of the normal-temperature gas is accelerated, so that a low-temperature air flow capable of air-cooling multiple split coolant flows is formed, thereby realizing the hot and cold alternation inside and outside the cabinet and reducing the high-temperature pressure of the cold cabinet itself.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 1-Figure 13 A multi-layer dynamic air-cooled freezer comprises a cabinet body 1 with a refrigerating chamber and a freezing chamber, wherein a refrigerating mechanism 2, an air supply part 3 and a heat dissipation part 4 are arranged in the cabinet body 1.

[0019] The cabinet 1 includes an evaporation case 11 and an extension case 12: The evaporator box 11 is fixedly installed at the top position of the cabinet 1, and the evaporator box 11 is used for the built-in evaporator 21. It should be noted that by setting the evaporator 21 for producing low temperature conditions at the top position of the cabinet 1, the influence of the compressor 22, the condenser 23 and the capillary tube 24 on the evaporator 21 can be reduced.

[0020] The extended chassis 12 is integrally connected to the rear end of the cabinet 1, and the extended chassis 12 is used for the built-in compressor 22, the condenser 23 and the capillary tube 24. It should be noted that the compressor 22, the condenser 23 and the capillary tube 24 are arranged in sequence from bottom to top. Figure 8 With attached Fig. 9 A return air pipe is connected between the evaporator 21 and the compressor 22 , an upper pipe for connecting one end of the capillary tube 24 is provided on the evaporator 21 , and a lower pipe for connecting the other end of the capillary tube 24 is provided on the condenser 23 .

[0021] The capillary tube 24 is vertically disposed between the condenser 23 and the evaporator 21 .

[0022] The refrigeration mechanism 2 includes an evaporator 21, a compressor 22, a condenser 23 and a capillary tube 24. The existing air-cooled refrigerator operates as follows through the refrigeration mechanism 2: First, the refrigeration mechanism 2 is filled with Freon-12 as a refrigerant. Freon-12 is vaporized from a low-pressure liquid into a gas in the evaporator 21, absorbing the heat in the cabinet 1, thereby reducing the temperature of the cabinet 1. Secondly, the gaseous Freon-12 is sucked into the compressor 22, compressed into a high-temperature and high-pressure gas by the compressor 22, and then discharged into the condenser 23; Then, in the condenser 23, the gaseous Freon-12 continuously releases heat to the surrounding space and gradually liquefies into liquid; Finally, the high-pressure liquid must flow through the capillary tube 24 and be throttled and depressurized before it can slowly flow into the evaporator 21, where it continuously vaporizes and absorbs heat to reduce the temperature.

[0023] As mentioned above, the refrigerator uses electrical energy to do work, and with the help of the physical change of the refrigerant, the heat around the evaporator 21 of the cabinet body 1 is transferred to the condenser 23 and then released, and the cycle continues over and over again to achieve the purpose of refrigeration.

[0024] The air supply part 3 transmits dry low-temperature cold air to the refrigerator compartment through the refrigeration mechanism 2, and transmits moist low-temperature cold air to the freezer compartment through the refrigeration mechanism 2. The air supply part 3 includes a first transmission pipeline 31, a first temperature controller 32, a first valve 33, a dehumidifier 34, a second transmission pipeline 35, a second temperature controller 36, a second valve 37, and a humidifier 38.

[0025] It should be noted that the evaporator box 11 is provided with a fan whose opening and closing is controlled by the first thermostat 32 and the second thermostat 36. When the temperature in the refrigerator or the freezer reaches the upper limit threshold, the low-temperature airflow in the evaporator box 11 can be driven to the first transmission pipe 31 or the second transmission pipe 35 by turning on the fan. Conversely, when the temperature in the refrigerator or the freezer reaches the lower limit threshold, the low-temperature airflow in the evaporator box 11 can be stopped from leaking out by turning off the fan.

[0026] The first transmission pipeline 31 is fixedly installed in the cabinet 1, and the first transmission pipeline 31 communicates with the evaporator case 11 and the refrigerating chamber.

[0027] The first thermostat 32 is disposed in the refrigerating chamber and is used to monitor the temperature condition in the refrigerating chamber. The opening and closing limit of the first thermostat 32 is set to -3~2°C through threshold setting.

[0028] The first valve 33 is adapted to be installed on the first transmission pipeline 31, and the dehumidifier 34 is adapted to be installed on the first transmission pipeline 31. The first thermostat 32 is electrically connected to the first valve 33 and the dehumidifier 34. When the temperature in the cold storage room rises to 2°C, the first thermostat 32 controls the first valve 33 and the dehumidifier 34 to open. The dehumidifier 34 is used to collect moisture in the low-temperature cold air to reduce the moisture content in the low-temperature cold air, thereby ensuring that the low-temperature cold air sent into the cold storage room is dry, thereby avoiding frost in the cold storage room.

[0029] The second transmission pipeline 35 is fixedly installed in the cabinet 1, and the second transmission pipeline 35 communicates with the evaporator case 11 and the freezer compartment.

[0030] The second thermostat 36 is arranged in the freezer compartment. The second thermostat 36 is used to monitor the temperature condition in the freezer compartment. The opening and closing limit of the second thermostat 36 is set to -25~-4°C through threshold setting. The second thermostat 36 is electrically connected to the second valve 37 and the humidifier 38. The first thermostat 32 and the second thermostat 36 are electrically connected to the purifier 310. When the temperature in the freezer compartment rises to -4°C, the second thermostat 36 controls the second valve 37, the humidifier 38 and the purifier 310 to open. The purifier 310 is used to purify the water vapor collected by the dehumidifier 34. The purified water vapor is mixed with the low-temperature cold air and enters the freezer compartment. Because the low-temperature cold air has high humidity, frost is more likely to form in the freezer compartment, thereby improving the freezing effect.

[0031] The second valve 37 is adapted to be installed on the second transmission pipeline 35 , and the humidifier 38 is adapted to be installed on the second transmission pipeline 35 .

[0032] It should be noted that: because the density of the low-temperature airflow in the evaporator box 11 is high and there is precipitation, the first transmission pipe 31 extends to the upper end of the evaporator box 11, and is used to transport the low-temperature airflow with a relatively large proportion of gas, while the second transmission pipe 35 extends to the lower end of the evaporator box 11. While driving the airflow to move, it also carries a larger proportion of water vapor to move.

[0033] The air supply unit 3 also includes a synchronous connecting pipe 39 and a purifier 310: The synchronous connecting pipe 39 connects the dehumidifier 34 and the humidifier 38, and the purifier 310 is adapted to be installed on the synchronous connecting pipe 39. It should be noted that the purifier 310 is provided to purify the water vapor to ensure the cleanliness of the frost formed on the object with the low-temperature airflow.

[0034] The heat dissipation part 4 is used for water cooling the compressor 22 and the condenser 23 in the refrigeration mechanism 2, and the heat dissipation part 4 includes a water cooling box frame 41, an air cooling pipe 42, an air inlet window 43, and an air outlet window 44. It should be noted that the air inlet window 43 and the air outlet window 44 are both connected to the extended chassis 12, and the air inlet window 43 and the air outlet window 44 are both provided with filters to improve the cleanliness of the airflow in and out of the cabinet 1.

[0035] Please refer to the instruction manual for details Fig. 9 , Attachment Fig.10 With attached Fig.13 The water cooling box frame 41 is arranged in the extended chassis 12 corresponding to the compressor 22 and the condenser 23, and the air cooling pipe 42 is arranged in the extended chassis 12 corresponding to the capillary tube 24. Fig.12 With attached Fig.13 : First, the water-cooling box frame 41 includes an aluminum foil hollow plate 411, a U-shaped hollow plate 412, a heat dissipation pipe group 413, and a powerful suction pump 414. An appropriate amount of coolant is filled in the water-cooling box frame 41, and through regular replenishment, the coolant can be reused for a long time. The low-temperature property of the coolant is used to provide a heat conduction effect for the compressor 22 and the condenser 23.

[0036] The aluminum foil hollow plate 411 is fixedly attached to the compressor 22 and the condenser 23. It should be noted that the aluminum foil hollow plate 411 adopts a straight plate structure, and an uneven structure adapted to the compressor 22 and the condenser 23 is formed on the surface to increase the contact area and improve the efficiency and level of the transfer of high-temperature heat from the compressor 22 and the condenser 23 to the aluminum foil hollow plate 411.

[0037] One end of the U-shaped hollow plate 412 is fixedly connected to the lower end of the aluminum foil hollow plate 411. It should be noted that a temperature control switch is provided at the connection position of the two. Only when the coolant in the aluminum foil hollow plate 411 absorbs enough high-temperature heat from the compressor 22 and the condenser 23 to reach a predetermined temperature, the temperature control switch is turned on, and the high-temperature coolant in the aluminum foil hollow plate 411 can enter the U-shaped hollow plate 412 and then be sucked back through the powerful suction pump 414.

[0038] The heat dissipation pipe group 413 is fixedly connected to the upper end of the aluminum foil hollow plate 411 and the other end of the U-shaped hollow plate 412. It should be noted that under the driving action of the powerful suction pump 414, the heat dissipation pipe group 413 distributes and transports the high-temperature coolant in strands. During this process, by transmitting normal-temperature air flow to the heat dissipation pipe group 413 and using the air flow to form a wind force effect, the high-temperature heat of the coolant in the heat dissipation pipe group 413 is accelerated, and this high-temperature heat is discharged outside the cabinet 1 through the air outlet window 44 due to the wind force effect.

[0039] The powerful suction pump 414 is arranged on the aluminum foil hollow plate 411, and the powerful suction pump 414 is used to extract the coolant in the aluminum foil hollow plate 411 into the U-shaped hollow plate 412.

[0040] Second, the air-cooling pipeline 42 includes a pressure-reducing pipe fitting 421, a cold air inlet pipe 422, and a cold air exhaust pipe 423: The pressure-reducing pipe fitting 421 is used to fixedly sleeve the capillary tube 24. The pressure-reducing pipe fitting 421 includes an upper thick-diameter port 4211, a middle thin-diameter short tube 4212, and a lower thick-diameter port 4213: The upper thick-diameter port 4211 is fixedly connected to the cold air intake pipe 422, the medium-thin-diameter short tube 4212 is integrally connected to the upper thick-diameter port 4211, and the lower thick-diameter port 4213 is integrally connected to the medium-thin-diameter short tube 4212. It is worth noting that in the process of the capillary tube 24 conveying liquid Freon-12 to the evaporator 21, although Freon-12 has released heat, its own temperature and the capillary tube 24 are still higher than the ambient temperature in the extension chassis 12, so the pressure-reducing pipe fitting 421 equipped with the capillary tube 24 is in a high-temperature and low-pressure state, that is, the "heat island effect", which helps to quickly absorb normal-temperature airflow to form wind effect.

[0041] It is further explained that because the diameter of the medium-thin diameter short tube 4212 in the pressure-reducing pipe 421 suddenly becomes smaller, it has the effect of pressurizing and speeding up the normal-temperature airflow passing through, and can further increase the movement speed of the normal-temperature airflow, thereby forming a wind effect, ensuring that it can form a strong and effective wind cooling effect on the heat dissipation tube group 413, and quickly dissipate the high-temperature heat of the coolant in the heat dissipation tube group 413.

[0042] The cold air intake pipe 422 is fixedly connected to the upper end of the pressure reducing pipe fitting 421, and the cold air intake pipe 422 extends to the outside of the cabinet 1 through the air intake window 43. An air inlet with an S-shaped cross-section structure is provided in the cold air intake pipe 422. It should be noted that because the interior of the pressure reducing pipe fitting 421 is in a low-pressure state, the normal temperature gas entering through the cold air intake pipe 422 is sucked into the pressure reducing pipe fitting 421. It is worth noting that the air inlet with an S-shaped cross-section structure can block dust, and the bent air intake channel structure is used to intercept dust impurities, so that the dust impurities are precipitated.

[0043] The cold air exhaust pipe 423 is fixedly connected to the lower end of the pressure reducing pipe 421 , and corresponds to the heat dissipation pipe group 413 , driving the airflow to pass through the heat dissipation pipe group 413 over a large area, which helps to increase the high-temperature heat conduction speed on the heat dissipation pipe group 413 .

[0044] The air inlet window 43 is opened at the rear end of the cabinet 1 corresponding to the extended chassis 12 , and the air inlet window 43 is flush with the air cooling duct 42 to facilitate the entry of normal temperature airflow outside the cabinet 1 .

[0045] The air outlet window 44 is opened at the rear end position of the cabinet 1 corresponding to the extended chassis 12, and the air outlet window 44 is flush with the water cooling box frame 41. The wind is used to dissipate the high-temperature heat on the heat dissipation pipe group 413, so that the high-temperature heat is discharged outside through the air outlet window 44 with the air flow, thereby reducing the temperature of the water cooling box frame 41 and the ambient temperature inside the extended chassis 12.

[0046] It should be noted that the specific model specifications of the refrigeration mechanism 2, the thermostat, the valve, the dehumidifier 34, the humidifier 38, the purifier 310 and the powerful suction pump 414 need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0047] The functional principle of the present invention can be described through the following operation modes: The first thermostat 32 is used to monitor and feedback the temperature condition of the refrigerating chamber. When the temperature of the refrigerating chamber rises to the upper limit threshold and cooling is required, the first valve 33 and the dehumidifier 34 are controlled to open, and dry and low-temperature cold air is conveyed to the refrigerating chamber through the first transmission pipe 31.

[0048] The second thermostat 36 is used to monitor the temperature condition of the freezer. When the temperature of the freezer rises to the upper limit threshold and cooling is required, the second valve 37 and the humidifier 38 are controlled to open. At the same time, the purifier 310 purifies the water vapor collected by the dehumidifier 34, and the purified water vapor enters the freezer after being mixed with the low-temperature cold air through the humidifier 38.

[0049] The coolant in the aluminum foil hollow plate 411 contacts the compressor 22 and the condenser 23, so that the high-temperature heat on the compressor 22 and the condenser 23 is transferred to the coolant. The high-temperature coolant is sequentially guided to the U-shaped hollow plate 412 and the heat dissipation pipe group 413 through the powerful suction pump 414. In this way, the reuse of the coolant can be realized, the utilization rate can be improved, and the cooling effect can also be ensured by regular replenishment.

[0050] In the condenser 23, the gaseous Freon-12 continuously releases heat to the surrounding space and gradually liquefies into a liquid. The high-pressure liquid flows through the capillary tube 24 for throttling and depressurization and slowly flows into the evaporator 21, so that the pressure-reducing pipe fitting 421 sleeving the capillary tube 24 generates low pressure due to high temperature. The normal-temperature gas outside the cabinet 1 enters the pressure-reducing pipe fitting 421 through the cold air inlet pipe 422. And because the caliber of the medium-thin and short pipe 4212 becomes smaller, the normal-temperature gas is accelerated to be discharged outside through the cold air exhaust pipe 423, forming an air flow with rapid movement, that is, the wind force for air-cooling the heat dissipation pipe group 413, and accelerating the discharge of the high-temperature heat in the extended chassis 12 to the outside.

[0051] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
