Description
Technical Field
[0001] The invention relates to the field of refrigerator application protection technology, and in particular to an air-cooling and direct-cooling interchangeable refrigerator. Background Art
[0002] In an environment with high humidity, if the direct cooling mode is always used, the freezer will be seriously frosted. In some scenarios with high requirements for temperature uniformity, the air cooling mode can play a good role. In order to meet the diverse needs of fresh-keeping, the existing air and direct cooling interchangeable freezers can switch the cooling mode according to the needs of users and the items stored. If users need to store some food that is easy to air-dry, they can switch the freezer to the direct cooling mode and use the better moisture retention of direct cooling to extend the shelf life of the food. When some meat needs to be quickly frozen or the temperature in the freezer needs to drop quickly, they can switch to the air cooling mode and use the characteristics of rapid cooling of air cooling.
[0003] Existing air-cooling and direct-cooling interchangeable refrigerators, such as the one disclosed in announcement number CN214581981U, believe that the traditional air-cooling method has poor air-cooling effect, and at the four corners of the device, it is proposed to start the vacuum pump through an external power supply to facilitate the air in the storage cabinet to be introduced into the connecting pipe through the vacuum pump, and then flow to the inside of the storage cabinet to achieve the effect of circulating air cooling. Protective structures are set on both sides of the protective outer shell to achieve the protective effect. However, in order to meet the complex temperature control needs, the condenser in the air-cooling dual system needs to run for a long time and continuously releases heat during operation. At the same time, the refrigerator is affected by the volume and space, so that the electrical components in the air-cooling dual system are stored in a centralized manner, which not only affects the refrigeration effect, but also makes the electrical components run at high load in a high-temperature environment for a long time. In particular, when the condenser lacks heat dissipation treatment, it will directly affect its cooperation with the evaporator and cannot produce low-temperature cold air for the refrigerator. For example, the direct air supply horizontal frost-free freezer disclosed in announcement number CN207317353U simplifies the air duct system into direct air supply through an axial flow fan with a large air volume, thereby improving the air circulation efficiency and eliminating the need to set a complex air duct structure in the interlayer of the hood. The entire air duct system has a simple structure and can meet the refrigeration requirements of a small-volume horizontal frost-free freezer with a short air supply distance. However, it only realizes the circulation of low-temperature cold air between the refrigerator and the freezer, making it difficult to effectively dissipate heat for electrical components such as the condenser, and it is especially difficult to discharge the high-temperature hot air accumulated in the freezer, so that the compressor, evaporator, condenser, etc. used to produce cold air can only operate under overload conditions under high temperature conditions, which not only affects the refrigeration effect, but also affects the safety of the freezer.

[0076] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0077] Refer to Figure 1-Figure 13A wind and direct cooling interchangeable refrigerator comprises a cabinet body 1 provided with a freezer compartment and a refrigerator compartment, the cabinet body 1 is provided with a wind direct cooling dual system 2, a first heat dissipation mechanism 3, and a second heat dissipation mechanism 4. It should be noted that by providing the wind direct cooling dual system 2, the cabinet body 1 can provide targeted cooling to the freezer compartment and the refrigerator compartment, and the cooling mode can be conveniently switched while effectively improving the cooling management level of the refrigerator.
[0078] The cabinet 1 includes a bottom cavity 11, a heat dissipation cavity 12, and a side cavity 13:
[0079] A bottom cavity 11 is opened at the lower end of the cabinet 1, and the bottom cavity 11 is used for the built-in direct air cooling dual system 2. It is worth noting that by opening the bottom cavity 11 at the bottom end of the cabinet 1, the space resources occupied by the freezer and refrigerator can be reduced, and it helps to increase the center of gravity stability of the cabinet 1.
[0080] The heat dissipation cavity 12 is opened at the rear end of the cabinet 1, and the heat dissipation cavity 12 is used for the built-in condenser 29, so that the condenser 29 with heat dissipation function is separately arranged in the heat dissipation cavity 12, reducing the impact on other electrical components in the direct air cooling dual system 2, and also facilitating independent heat dissipation maintenance of the condenser 29.
[0081] The side cavity 13 is opened on the side wall of the cabinet 1, and the side cavity 13 is used for the built-in direct air cooling dual system 2. It should be noted that there are two side cavities 13, corresponding to the freezer and refrigerator respectively, so as to distinguish and place the air-cooled freezer evaporator 22, the freezer capillary 23 and the direct cooling refrigerator evaporator 24, the refrigerator capillary 25.
[0082] The air direct cooling dual system 2 is used to provide cooling for the freezer compartment and the refrigerator compartment, and the air direct cooling dual system 2 includes a condenser 29. Figure 4 With attached Figure 5 The air direct cooling dual system 2 also includes a compressor 21, an air-cooled freezer chamber evaporator 22, a freezer chamber capillary 23, a direct cooling refrigerator chamber evaporator 24, a refrigerator chamber capillary 25, a double-control solenoid valve 26, a drying filter 27 and a fan 28. The air direct cooling dual system 2 works in the same way as a wind and direct cooling interchangeable freezer, so it is not described in detail.
[0083] The first heat dissipation mechanism 3 cools down the protective condenser 29 by air cooling. Figure 6 -Attached Fig. 9 The first heat dissipation mechanism 3 includes an air inlet 31, an air outlet 32, and a flow increasing portion 33:
[0084] The air inlet 31 is used to deliver cold air into the heat dissipation cavity 12. The air inlet 31 is opened at the lower end of the cabinet 1 and is connected to the bottom of the heat dissipation cavity 12. The air inlet 31 includes a hook-shaped air inlet cavity 311, a three-way cavity 312, a heat conduction cavity 313, and a storage cavity 314:
[0085] The hook-shaped air inlet channel 311 is opened inside the lower end of the cabinet body 1, and the upper end of the hook-shaped air inlet channel 311 communicates with the heat dissipation cavity 12. For details, refer to the attached Figure 7 description. The lower end of the hook-shaped air inlet channel 311 extends outside the cabinet body 1, and a filter screen is provided to filter and purify the cold air flow entering the cabinet body 1. At the same time, the hook-shaped air inlet channel 311 is used to increase the difficulty of impurities and dust in the cold air flow entering the cabinet body 1.
[0086] Two of the ports of the tee channel 312 communicate with the hook-shaped air inlet channel 311. It should be noted that there is a height difference between the two ports of the tee channel 312 connected to the hook-shaped air inlet channel 311. The upper port is used to transport the cold air flow from the hook-shaped air inlet channel 311 to the tee channel 312, and the lower port is used to transport the cold air flow from the tee channel 312 to the hook-shaped air inlet channel 311.
[0087] The heat conduction cavity 313 is located between the heat dissipation cavity 12 and the hook-shaped air inlet channel 311. The storage cavity 314 communicates with the other port of the tee channel 312. It should be noted that the T-shaped heat conduction member 333 and the booster piston 335 are fixedly connected through the heat conduction cavity 313 and the storage cavity 314.
[0088] The air outlet 32 is used to transport the hot air flow in the heat dissipation cavity 12 to the outside of the cabinet body 1. The air outlet 32 is opened at the middle position of the cabinet body 1, and the air outlet 32 communicates with the top end of the heat dissipation cavity 12. The air outlet 32 includes a first C-shaped channel 321, a second C-shaped channel 322, and a diameter-changing channel 323. For details, refer to the attached Figure 6 description. The air outlet 32 is a horizontal S-shaped structure:
[0089] The first C-shaped channel 321 is opened inside the middle end of the cabinet body 1, and the lower end of the first C-shaped channel 321 communicates with the heat dissipation cavity 12. One end of the second C-shaped channel 322 communicates with the upper end of the first C-shaped channel 321. For details, refer to the attached Fig. 9 description. Because of the high-temperature condition in the heat dissipation cavity 12, point a close to the heat dissipation cavity 12 is in a high-temperature and low-pressure state, while point b is in a low-temperature and high-pressure state. Due to the air pressure difference, there is an adsorption effect on the hot air flow in the heat dissipation cavity 12.
[0090] One end of the diameter-changing channel 323 communicates with the other end of the second C-shaped channel 322. The diameter-changing channel 323 includes a lower thick-diameter channel 3231, a middle thin-diameter channel 3232, and an upper thick-diameter channel 3233:
[0091] The lower thick-diameter channel 3231 communicates with one end of the second C-shaped channel 322 that is far from the first C-shaped channel 321. The middle thin-diameter channel 3232 communicates with the lower thick-diameter channel 3231, and the upper thick-diameter channel 3233 communicates with the middle thin-diameter channel 3232. Moreover, the upper thick-diameter channel 3233 extends outside the cabinet body 1. It should be noted that the lower thick-diameter channel 3231 and the upper thick-diameter channel 3233 have the same pipe diameter, while the pipe diameter of the middle thin-diameter channel 3232 is smaller than that of the lower thick-diameter channel 3231 and the upper thick-diameter channel 3233, that is, a Laval tube. According to:
[0092] Flow rate = Flow velocity × Cross-sectional area
[0093] It can be known that when the flow rate is constant and the cross-sectional area decreases, the flow velocity increases, enabling the hot air flow to circulate rapidly in the diameter-changing channel 323.
[0094] The flow rate increasing part 33 is used to accelerate the cold air flow in the air inlet 31 to impact the hot air flow in the heat dissipation cavity 12. The flow rate increasing part 33 squeezes the hot air flow in the heat dissipation cavity 12 through the cold air flow in the air inlet 31 and discharges it through the air outlet 32. The flow rate increasing part 33 includes a baffle plate assembly 331, a memory spring 332, a T-shaped heat conducting member 333, a pressure increasing piston 335, a first one-way valve 336, and a second one-way valve 337:
[0095] The baffle plate assembly 331 is fixedly installed in the hook-shaped air intake channel 311. By setting the baffle plate assembly 331, impurities mixed in the cold air flow can be blocked.
[0096] The memory spring 332 is fixedly arranged in the heat conducting cavity 313. The memory spring 332 is made of nickel-titanium alloy, which is a special alloy that can automatically restore its plastic deformation to the original shape at a certain specific temperature, with a stretch rate of more than 20% and a fatigue life of up to 1×10 7 times, and the damping characteristic is 10 times higher than that of an ordinary spring. By setting the deformation temperature threshold, in the initial state, the memory spring 332 is in a contracted state. When its own temperature rises or falls to the deformation threshold, it quickly extends, thereby driving the T-shaped heat conducting member 333 to move telescopically between the hook-shaped air intake channel 311 and the heat conducting cavity 313.
[0097] The T-shaped heat conducting member 333 is fixedly connected to the memory spring 332, and a heat conducting through hole 334 is opened at one end of the T-shaped heat conducting member 333 that extends into the hook-shaped air intake channel 311. Specifically, refer to the attached Figure 8 to the specification. The T-shaped heat conducting member 333 is a hollow structure. Through the heat conducting through hole 334, part of the cold air flow in the hook-shaped air intake channel 311 can enter the heat conducting cavity 313.
[0098] The pressure increasing piston 335 is fixedly connected to the T-shaped heat conducting member 333, and the pressure increasing piston 335 extends into one end of the three-way channel 312 that communicates with the storage cavity 314.
[0099] The first one-way valve 336 is installed on one end of the three-way cavity 312 connected to the middle end of the hook-shaped air intake cavity 311. When the booster piston 335 contracts into the receiving cavity 314, part of the cold air flow in the hook-shaped air intake cavity 311 enters into the three-way cavity 312. The second one-way valve 337 is installed on one end of the three-way cavity 312 connected to the lower end of the hook-shaped air intake cavity 311. When the booster piston 335 extends into the three-way cavity 312, the cold air flow in the three-way cavity 312 enters into the hook-shaped air intake cavity 311 to form an impact effect on the cold air flow in the hook-shaped air intake cavity 311.
[0100] The second heat dissipation mechanism 4 cools down the protective condenser 29 by water cooling, and the second heat dissipation mechanism 4 includes a cold water storage tank 41, a hot water storage tank 42, a cooling coil 43, a return pipe 44, a strong suction pump 45, and a branch heat dissipation element 46:
[0101] The cold water storage tank 41 is fixedly disposed in one side of the heat dissipation cavity 12 , and the hot water storage tank 42 is fixedly disposed in the other side of the heat dissipation cavity 12 .
[0102] It should be noted that the cooling coil 43 is used to connect the cold water storage tank 41 and the hot water storage tank 42 in one direction, and the cooling coil 43 is mounted on the condenser 29. Low-temperature cold water cools the condenser 29 through the cooling coil 43, and the condenser 29 is cooled by water at a level higher than that of air cooling.
[0103] The return pipe 44 is used to connect the hot water storage tank 42 and the cold water storage tank 41 in one direction. The return pipe 44 includes a branch connector 441 and a loop branch pipe 442:
[0104] There are two branch connectors 441 , and the two branch connectors 441 are installed on the hot water storage tank 42 and the cold water storage tank 41 in a matching manner.
[0105] The loop branch pipe 442 is installed between the two branch connectors 441 , and at least three loop branch pipes 442 are used to realize the branch reflux of hot water, so that each loop branch pipe 442 can be cooled quickly and independently.
[0106] The powerful suction pump 45 is connected to the hot water storage tank 42 through the return pipe 44. Under the action of the powerful suction pump 45, the hot water in the hot water storage tank 42 can flow back to the cold water storage tank 41. In this process, the return pipe 44 is cooled to quickly cool the hot water for easy recycling.
[0107] The shunt heat sink 46 is fixedly disposed in the heat sink cavity 12 corresponding to the return pipe 44. The shunt heat sink 46 includes an aluminum foil plate 461, an embedding groove 462, a sealing cavity 463, a temperature sensor 464, and a synchronous solenoid valve 465:
[0108] The aluminum foil plate 461 is fixedly installed in the heat dissipation cavity 12 .
[0109] The embedding groove 462 is formed in the aluminum foil plate 461 , and the embedding groove 462 is used to fit the circuit branch pipe 442 .
[0110] The sealing cavity 463 is opened in the aluminum foil plate 461 , and the sealing cavity 463 is connected to the embedding groove 462 . The sealing cavity 463 is filled with ethanol solution.
[0111] The temperature sensor 464 is fixedly mounted on the aluminum foil plate 461, and the synchronous solenoid valve 465 is mounted on the sealed cavity 463, and the synchronous solenoid valve 465 is electrically connected to the temperature sensor 464. The temperature sensor 464 is used to monitor the temperature of the return pipe 44. When the temperature of the return pipe 44 reaches the upper limit threshold, ethanol solution is sprayed, and the ethanol solution absorbs heat during the evaporation process to consume the high-temperature heat on the branch heat sink 46 and the loop branch pipe 442.
[0112] The shunt heat sink 46 corresponds to one end of the hook-shaped air inlet channel 311 connected to the heat sink 12 . It should be noted that the shunt heat sink 46 can also be cooled by air using the cold air flow entering the heat sink 12 from the hook-shaped air inlet channel 311 .
[0113] The cold water storage tank 41 is provided with a first liquid replenishing port to replenish cold water into the cold water storage tank 41 , and the aluminum foil plate 461 is provided with a second liquid replenishing port connected to the sealing cavity 463 to replenish ethanol solution into the branch heat sink 46 .
[0114] It should be noted that the specific models and specifications of the direct air cooling dual system 2, the powerful suction pump 45, the temperature sensor 464 and the synchronous solenoid valve 465 need to be selected and determined according to the actual specifications of the device, and the specific selection and calculation method adopts the existing technology in the field, so it is not repeated here.
[0115] The present invention can be explained by the following operation mode:
[0116] The cold air outside the cabinet 1 flows through the hook-shaped air inlet cavity 311 and enters the air inlet 31, and is intercepted and slowed down by the deflection baffle assembly 331, and then continues to enter after being screened. The low temperature transmitted by the T-shaped heat conductor 333 causes the memory spring 332 to cool down and then shrink and deform, so that the T-shaped heat conductor 333 drives the boost piston 335 to extend into the three-way cavity 312, so as to accelerate the cold air flow in the three-way cavity 312 to re-enter the hook-shaped air inlet cavity 311, and accelerate the cold air flow in the hook-shaped air inlet cavity 311 to enter the heat dissipation cavity 12, thereby reducing the ambient temperature in the heat dissipation cavity 12.
[0117] The cold water in the cold water storage tank 41 is made to flow orderly into the hot water storage tank 42 by using the cooling coil 43, while cooling the condenser 29, the water flowing into the hot water storage tank 42 is heated up. The hot water in the hot water storage tank 42 is driven by the powerful suction pump 45 to flow back to the cold water storage tank 41 through the return pipe 44. The temperature sensor 464 on the shunt heat dissipation component 46 monitors the temperature of the return pipe 44. When the temperature reaches the upper limit threshold, the synchronous solenoid valve 465 is controlled to open, so that the ethanol solution in the sealed cavity 463 is sprayed on the loop branch pipe 442, and the environmental temperature in the heat dissipation cavity 12 is reduced by the heat absorption and evaporation of the ethanol solution.
[0118] Because the condenser 29 continuously releases heat, the position of point a is in a high-temperature and low-pressure state, while the position of point b is in a low-temperature and high-pressure state, thus forming an adsorption effect on the hot air flow in the heat dissipation cavity 12. The hot air flow in the heat dissipation cavity 12 enters the diameter-changing cavity 323 successively through the first U-shaped cavity 321 and the second U-shaped cavity 322. Because the diameter of the middle and thin diameter cavity 3232 suddenly decreases, the flow rate of the hot air flow is accelerated at the position of point c, so that the hot air flow doped with the evaporated ethanol solution is quickly discharged outside the cabinet body 1.
[0119] The above is only a preferred specific embodiment 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
