Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigeration device. Background Art

[0002] A refrigerator is a household appliance commonly used in people's daily lives. A refrigerator usually includes a box body and a door body. A refrigeration compartment is formed in the box body to place items that need to be refrigerated and stored. The refrigeration compartment is opened and closed through the door body to facilitate users to store and retrieve items. At present, most commonly used refrigerators use air cooling for refrigeration. For general refrigerator-freezers with storage compartments distributed up and down, they can be divided into two types: a freezer compartment at the bottom and a refrigerator compartment at the top (i.e., an upper storage and lower freezing structure) and a freezer compartment at the top and a refrigerator compartment at the bottom (i.e., an upper freezing and lower storage structure).

[0003] In a traditional air-cooled refrigerator with freezing on top and storage on the bottom, the evaporator is usually set on the back of the freezer. The pressure of the refrigerant in the refrigeration cycle system is reduced after capillary throttling. When flowing through the evaporator, it exchanges heat with the evaporator to achieve endothermic evaporation, thereby reducing the temperature of the evaporator and providing a cold source for refrigerator refrigeration. However, the evaporator is set on the back of the freezer, which makes the circulation distance of the refrigeration air path too long and the circulation resistance of the refrigeration air path too large, thereby reducing the refrigeration air supply efficiency and the refrigeration efficiency of the whole machine. In view of this, how to design a technology that can shorten the circulation distance of the refrigeration air path and reduce the circulation resistance of the refrigeration air path to improve the refrigeration air supply efficiency and the refrigeration efficiency of the whole machine is the technical problem to be solved by the utility model.

[0069] High volume ratio is the development trend of the refrigerator industry. With the development of insulation technology, it is difficult to reduce the thickness of the foam layer to increase the usable volume of the refrigerator by reducing the thermal conductivity of traditional foam materials or improving the thermal insulation performance of foam materials. At present, vacuum insulation panels are mainly used to improve thermal insulation performance and reduce the thickness of foam materials, but the cost often increases a lot, resulting in a higher overall cost of the product. Therefore, appropriately adjusting the layout of the refrigerator to increase the usable volume of the refrigerator is a new solution.

[0070] In the first aspect, combined Figures 1 to 11 As shown, an embodiment of the present disclosure provides a refrigeration device, which includes an outer shell, a freezing inner tank 1, a freezing door body, a freezing partition 2, a refrigeration system, a first partition 3, a refrigerated inner tank 4, a refrigerated door body, a second partition 413, a refrigerated air supply unit 5, and a refrigerated air return unit 6.

[0071] The freezing liner 1 and the refrigerating liner 4 are both arranged in the outer shell, and the refrigerating liner 4 is arranged below the freezing liner 1.

[0072] Combination Figure 2 As shown, a freezing chamber 11 is formed inside the freezing inner container 1 .

[0073] The freezing partition 2 is disposed in the freezing chamber 11 in a transverse direction, and divides the freezing chamber 11 into a freezing chamber 111 and a refrigerating chamber 112. The refrigerating chamber 112 is located at the lower part of the freezing chamber 111, that is, the refrigerating chamber 112 is located at the bottom of the freezing chamber 11, wherein the freezing chamber 111 is used for freezing food, and a freezing return air port 21 is provided at an opening end of the freezing partition 2 close to the freezing chamber 11;

[0074] Combination Figure 3 As shown, the first partition 3 is arranged in the freezing chamber 111 along the vertical direction, and the freezing chamber 111 is divided into a freezing air supply channel 1111 and a freezing storage chamber 1112. The freezing air supply channel 1111 is located between the first partition 3 and the rear side wall of the freezing liner 1. The bottom end of the freezing air supply channel 1111 is connected to the refrigerating chamber 112. The first partition 3 is provided with a freezing air supply port 31. The freezing air supply port 31 connects the freezing air supply channel 1111 and the freezing storage chamber 1112. The freezing air supply port 31 is used for the refrigerating chamber 112 to transport cold air to the freezing storage chamber 1112 through the freezing air supply channel 1111; the freezing return air port 21 connects the freezing storage chamber 1112 and the refrigerating chamber 112. The freezing return air port 21 is used for the freezing storage chamber 1112 to transport air that has undergone heat exchange with the medium in the freezing storage chamber 1112 to the refrigerating chamber 112.

[0075] The refrigeration chamber 112 , the refrigeration air supply passage 1111 , the refrigeration air supply port 31 , the refrigeration storage chamber 1112 , the refrigeration air return port 21 , and the refrigeration chamber 112 are cyclically connected in sequence to form an air refrigeration circulation loop in the refrigeration chamber 11 .

[0076] Combination Figure 2 As shown, in certain embodiments of the present application, a freezing air duct cover 32 is provided on the first partition 3, and the freezing air duct cover 32 is located in the freezing air supply channel 1111, and the freezing air duct cover 32 mainly serves to guide the cold air and promote the cold air to be transported from the refrigeration chamber 112 to the frozen storage chamber 1112.

[0077] Combination Figure 4 As shown, the refrigerating inner liner 4 is arranged below the freezing inner liner 1, and a refrigerating chamber 41 is formed in the refrigerating inner liner 4, and the refrigerating chamber 41 is used to refrigerate and preserve food.

[0078] The second partition 413 is arranged in the refrigerating chamber 41 along the vertical direction to divide the refrigerating chamber 41 into a refrigerating air supply channel 411 and a refrigerating storage chamber 412. The refrigerating air supply channel 411 is located between the second partition 413 and the rear side wall of the refrigerating liner 4. The second partition 413 is provided with a refrigerating air outlet 4131, which is used to connect the refrigerating air supply channel 411 and the refrigerating storage chamber 412.

[0079] Combination Figure 5 and Figure 6 As shown, the refrigerated air supply unit 5 and the refrigerated air return unit 6 are arranged between the freezing inner tank 1 and the refrigerated inner tank 4, the refrigerated air supply unit 5 is used to connect the refrigeration chamber 112 and the refrigerated air supply channel 411, and the refrigerated return unit 6 is used to connect the refrigeration chamber 112 and the refrigerated storage chamber 412.

[0080] Specifically, a refrigerated air supply port 51 is formed on the refrigerated air supply unit 5, and a refrigerated air return port 61 is formed on the refrigerated air return unit 6. The refrigerated air supply port 51 connects the refrigerating chamber 112 with the refrigerated air supply passage 411, and the refrigerated air return port 61 connects the refrigerating chamber 112 with the refrigerating chamber 112. The refrigerated air supply port 51 is used for the refrigerating chamber 112 to transport cold air to the refrigerated air supply passage 411, and the refrigerated air return port 61 is used for the refrigerating chamber 412 to transport gas for heat exchange with the medium in the refrigerated storage chamber 412 to the refrigerating chamber 112. The refrigerating chamber 112, the refrigerated air supply port 51, the refrigerated air supply passage 411, the refrigerated air outlet 4131, the refrigerated storage chamber 412, the refrigerated air return port 61, and the refrigerating chamber 112 are sequentially connected to form an air refrigeration circulation loop in the refrigerating chamber 41.

[0081] It should be noted that, since the freezing liner 1 and the refrigerating liner 4 are independently provided, and the refrigerating chamber 112 is located at the bottom of the freezing liner 1, a refrigerating air supply port 51 and a refrigerating air return port 61 are provided in the refrigerating liner and the freezing liner, respectively.

[0082] In some embodiments, one opening of the refrigerated air supply vent 51 is located at the lower portion of the rear side wall of the freezing inner container 1 , and the other opening of the refrigerated air supply vent 51 is located at the upper portion of the rear side wall of the refrigerated inner container 4 .

[0083] In other embodiments, one of the refrigerated air supply vents 51 is located on the bottom wall of the freezing inner container 1 , and the other refrigerated air supply vent 51 is located on the top wall of the refrigerated inner container 4 .

[0084] In certain embodiments of the present application, the refrigerated air supply unit 5 is located at the rear side of the evaporator 7 , and the refrigerated air return unit 6 is located at the front side of the evaporator 7 .

[0085] In some embodiments of the present application, the refrigeration system includes a compressor, a condenser, a cooling fan, a throttling device, an evaporator 7 and a fan 8. The fan 8 and the evaporator 7 are both arranged in the refrigeration chamber 112.

[0086] The compressor, condenser, throttling device and evaporator 7 are connected by pipelines to form a refrigerant circulation loop. The compressor and throttling device are generally arranged at the bottom of the refrigeration equipment. The refrigeration system performs the refrigeration cycle of the refrigeration equipment by using the compressor, condenser, throttling device and evaporator 7. The refrigeration cycle process includes a series of processes involving compression, condensation, throttling cooling and evaporation to achieve refrigeration of the air in the refrigeration equipment.

[0087] First, the low-temperature, low-pressure refrigerant gas enters the compressor, which compresses the low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure refrigerant gas and discharges it; the discharged refrigerant gas flows into the condenser for condensation and cooling. In the condenser, the refrigerant condenses into a liquid phase, and under the action of the cooling fan, the heat is released into the surrounding environment through the condensation process.

[0088] The liquid refrigerant flowing out of the condenser enters the throttling device for further throttling and cooling, forming a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant enters the evaporator 7, which is arranged in the refrigeration chamber 112. In the evaporator 7, the low-temperature, low-pressure liquid refrigerant evaporates and absorbs heat to form a refrigerant gas, which finally returns to the compressor for the next cycle. The evaporator 7 can cool and cool the air in the refrigeration chamber 112 by utilizing the heat absorbed by the evaporation of the refrigerant, and then the cold air is sent into the refrigeration chamber 41 and the freezer compartment 111 through the fan 8.

[0089] Specifically, the present application divides the freezing chamber 111 into a freezing air supply channel 1111 and a freezing storage chamber 1112 by means of a first partition 3; the refrigerating inner tank 4 is located below the freezing inner tank 1, and a refrigerating chamber 41 is formed therein; the second partition 413 divides the refrigerating chamber 41 into a refrigerating air supply channel 411 and a refrigerating storage chamber 412. In this way, the cold air in the refrigerating chamber 112 flows upward through the refrigerating air supply channel 1111, the refrigerating air supply port 31, the freezing storage chamber 1112, and the refrigerating return air port 21 to return to the refrigerating chamber 112; and flows downward through the refrigerating air supply unit 5, the refrigerating air supply channel 411, the refrigerating air outlet 4131, the refrigerating storage chamber 412, and the refrigerating return air unit 6 to return to the refrigerating chamber 112, thereby shortening the length of the refrigerating air path circulation of the top-freezing and bottom-hiding refrigerator, greatly reducing the resistance of the refrigerating air path circulation, and being beneficial to improving the refrigerating air supply efficiency and the refrigeration efficiency of the entire machine.

[0090] Combination Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the fan 8 is obliquely arranged at the rear side of the evaporator 7 in the refrigeration chamber 112, and is located at the junction of the refrigeration chamber 112 and the freezing air supply channel 1111. The fan 8 is configured to deliver the cold air in the refrigeration chamber 112 into the freezing air supply channel 1111 and into the refrigeration air supply channel 411 through the refrigeration air supply unit 5; and to suck the air in the freezing storage chamber 1112 into the refrigeration chamber 112 through the freezing return air port 21 and the air in the refrigeration storage chamber 412 through the refrigeration return air unit 6.

[0091] In this way, the distance between the fan 8 and the freezing air supply port 31 and the refrigeration air supply port 51 is closer, which can reduce the circulation distance of the refrigeration air path and reduce the resistance of air supply.

[0092] At the same time, the refrigerated return air inlet 61 and the frozen return air inlet 21 are both located on the other side of the evaporator 7, that is, the frozen return air inlet 21 is located at the bottom and front of the frozen storage chamber 1112; the refrigerated return air inlet 61 is located at the top and front of the refrigerated storage chamber 412, which reduces the refrigerated return air path and the resistance of the refrigerated return air, which is beneficial to improving the refrigeration efficiency.

[0093] In other embodiments of the present application, the refrigerated air supply section 5 and the refrigerated return air section 6 are both flat tubular structures, and the refrigerated air supply section 5 and the refrigerated return air section 6 are arranged along the width direction of the freezing inner tank 1. This can enhance the circulation efficiency of the refrigerated air duct. While improving the return air efficiency, it can improve the problem of uneven frosting on the surface of the evaporator 7, which is beneficial to improving the heat exchange efficiency of the evaporator 7.

[0094] In some other embodiments of the present application, the angle between the axis of the fan 8 and the vertical direction is α, 10°≤α≤45°.

[0095] Exemplarily, the angle α is 15° or 30°.

[0096] In some embodiments of the present application, the fan 8 is located at the opening side of the evaporator 7 away from the freezing tank 1, and the fan 8 includes a centrifugal fan or a cross-flow fan.

[0097] Specifically, by arranging the fan 8 on the side of the opening of the evaporator 7 away from the freezing liner 1, the fan 8 is close to the freezing air supply port 31 and the refrigerating air supply port 51, so that the fan 8 can send the cold air in the refrigerating chamber 112 into the freezing chamber 111 and the refrigerating chamber 41 through the freezing air supply port 31. In this way, the circulation distance of the refrigerating air path can be reduced, and the resistance of air supply can be reduced.

[0098] In some embodiments of the present application, the refrigeration equipment further includes a freezing air volume adjustment unit and / or a refrigerating air volume adjustment unit.

[0099] The refrigeration air volume adjustment unit is disposed in the refrigeration air supply passage 1111, and is configured to adjust the air supply volume in the refrigeration air supply passage 1111;

[0100] The refrigeration air volume adjustment unit is disposed in the refrigeration air supply passage 411 , and is configured to adjust the air supply volume in the refrigeration air supply passage 411 .

[0101] In this application, combined Fig.10As shown, the air refrigeration cycle process in the refrigeration equipment is as follows: the evaporator 7 in the refrigeration chamber 112 cools and cools the air in the refrigeration chamber 112 to form cold air, and the fan 8 runs to blow a part of the cold air flow upward to the freezing air supply channel 1111, and is sent into the frozen storage chamber 1112 through the freezing air supply port 31 on the first partition 3 through the freezing air supply channel 1111. After the air flow exchanges heat with the food (or air) in the frozen storage chamber 1112, it flows back to the front end of the evaporator 7 in the refrigeration chamber 112 from the freezing return air port 21 located at the front end of the freezing partition 2 and at the bottom of the frozen storage chamber 1112, thereby realizing the air circulation of the freezing chamber 11.

[0102] At the same time, the operation of the fan 8 will blow another part of the cold air flow downward through the refrigerated air supply port 51 to the refrigerated air supply channel 411, and then be sent into the refrigerated storage chamber 412 through the refrigerated air outlet 4131 on the second partition 413 through the refrigerated air supply channel 411. After the air flow has exchanged heat with the food (also including air) in the refrigerated storage chamber 412, it flows back from the refrigerated return air port 61 at the front end and top of the refrigerated storage chamber 412 to the front end of the evaporator 7 in the refrigeration chamber 112, thereby realizing air circulation in the refrigerated chamber 41.

[0103] In some other embodiments of the present application, the refrigeration return air inlet 21 is located at the front side of the evaporator 7 , and the refrigeration return air inlet 21 is located directly above the refrigeration return air portion 6 .

[0104] Combination Figure 2 and Fig.11 As shown, in some embodiments of the present application, the bottom wall of the freezing container 1 is tilted downward in a direction away from the opening of the freezing container 1, that is, the bottom of the freezing container 1 is tilted backward and downward, and a drain port 121 is formed at the lowest point of the bottom wall of the freezing container 1; the drain pipe 122 is sealed and connected to the drain port 121;

[0105] Usually, during the use of the evaporator 7, the evaporator 7 is often frosted due to insufficient refrigerant, low compressor efficiency, excessive refrigerant, dirty heat exchanger, too low temperature setting, bad or improper installation of temperature probe, small indoor air volume, poor system matching, etc. The frosting of the evaporator 7 not only affects the efficiency of the refrigeration equipment, but also may cause damage to the equipment. Therefore, the evaporator 7 needs to be defrosted regularly.

[0106] After defrosting, the frost layer of the evaporator 7 will melt into water, and bacteria, dust and other pollutants are easily attached to the water. By tilting the bottom wall of the freezing tank 1 downward in a direction away from the opening of the freezing tank 1, a drain port 121 is formed at the lowest point of the bottom wall of the freezing tank 1, and a drain pipe 122 is sealed and connected to the drain port 121, so that the water generated by the evaporator 7 in the refrigeration chamber 112 during the defrosting process can be discharged through the drain port 121 in time, reducing the growth of bacteria and helping to maintain the environmental hygiene in the freezing chamber 111 and the cold storage chamber 41.

[0107] Specifically, the freezing partition 2 divides the freezing chamber 11 into a freezing chamber 111 and a refrigerating chamber 112. The refrigerating chamber 112 is located at the lower part of the freezing chamber 111. The refrigerating liner 4 is arranged below the freezing liner 1. A refrigerating chamber 41 is formed in the refrigerating liner 4. The refrigerating chamber 41 is connected to the refrigerating chamber 112 through a refrigerating air supply port 51 and a refrigerating air return port 61. The fan 8 and the evaporator 7 are arranged in the refrigerating chamber 112. The fan 8 can respectively send the cold air in the refrigerating chamber 112 into the freezing chamber 111 and the refrigerating chamber 41, and suck the air in the freezing chamber 111 and the refrigerating chamber 41 into the refrigerating chamber 112. The fan 8 and the evaporator 7 are located at the bottom of the freezing liner 1 and will not occupy the longitudinal space of the freezing chamber 11, thereby increasing the depth of the freezing chamber 11, which is beneficial to improving the use volume of the refrigeration equipment and enhancing the user experience.

[0108] In some embodiments of the present application, the evaporator 7 and the bottom wall of the freezing container 1 have a consistent inclination angle.

[0109] Specifically, by setting the evaporator 7 to be consistent with the inclination angle of the bottom wall of the freezing inner container 1, on the one hand, the space in the refrigeration chamber 112 can be fully utilized to improve the space utilization rate.

[0110] On the other hand, during the operation of the refrigeration equipment, moisture in the air is condensed to form a water film, bacteria and dust in the water film will be adsorbed on the water droplets, part of the water droplets will drip under the action of gravity and be discharged by the drain pipe 122, and the other part of the water film will remain on the surface of the evaporator 7 to form a thin water film. By tilting the evaporator 7, the water on the surface of the evaporator 7 can be quickly dripped, reducing the formation of the water film on the surface of the evaporator 7, so that the evaporator 7 can work more stably.

[0111] In some embodiments of the present application, the bottom wall of the evaporator 7 and the freezing container 1 are inclined at an angle β to the horizontal direction, and 2°≤β≤10°.

[0112] Exemplarily, the inclined angle β between the evaporator 7 and the bottom wall of the freezing container 1 and the horizontal direction is 5°, 6°, 7° or 8°.

[0113] In some embodiments of the present application, the lowest point of the bottom wall of the freezing inner tank 1 is concave to form a water collecting portion 12, and the water collecting portion 12 has a conical structure, which is convenient for the water collecting portion 12 to collect water. A drain port 121 is formed on the water collecting portion 12, and the drain pipe 122 is located on the rear side of the refrigeration inner tank 4.

[0114] Specifically, in the present application, the drainage design of the drain port 121 and the drain pipe 122 relies on the gravity of water to drain downward, and the freezing tank 1 is located above the refrigeration tank 4, and the drain pipe 122 is located on the rear side of the refrigeration tank 4, and the temperature of the refrigeration tank 4 is generally above 0°C. In this way, there is no need to consider the problem of ice formation in the drain pipe 122, which is conducive to simplifying structural components and reducing production costs.

[0115] After the refrigeration equipment has been used for a period of time, frost will usually appear on the evaporator 7. Since the door of the refrigeration equipment is often opened, humid air will enter the interior of the refrigeration equipment and easily condense into a frost layer when encountering the low temperature evaporator 7. If the frost layer is not cleaned in time, it will become thicker and thicker. In severe cases, it will cause the thermal efficiency of the refrigerator to decrease.

[0116] In some embodiments of the present application, the refrigeration device further includes a defrost heater 71 .

[0117] The defrost heater 71 is connected to the evaporator 7 and is located below the evaporator 7 . The defrost heater 71 is configured to remove frost on the evaporator 7 .

[0118] Specifically, a slot is formed on the evaporator 7, and the slot is used to fix the defrost heater 71. By providing the defrost heater 71, the frost on the evaporator 7 can be melted to keep the inside of the refrigeration device dry and clean.

[0119] In some embodiments of the present application, the refrigerated return air inlet 21 and the refrigerated return air inlet 61 are located on the front side of the evaporator 7, the refrigerated supply air inlet 31 and the refrigerated supply air inlet 51 are located on the rear side of the evaporator 7, and the defrost heater 71 is densely arranged near the refrigerated return air inlet 21 than far away from the refrigerated return air inlet 21.

[0120] Specifically, since the refrigerated air supply port 31 and the refrigerated air supply port 51 are located on the rear side of the evaporator 7, and the refrigerated return air port 21 and the refrigerated return air port 61 are located on the front side of the evaporator 7, the front end of the evaporator 7 is more severely frosted. By arranging the defrost heaters 71 more densely near the refrigerated return air port 21 than far away from the refrigerated return air port 21, defrosting can be performed faster, thereby improving the defrosting efficiency of the refrigeration equipment.

[0121] In some embodiments of the present application, the evaporator 7 includes a fin-type evaporator 7 or a parallel-flow evaporator 7 .

[0122] Specifically, the evaporator 7 adopts a fin-type evaporator 7 or a parallel-flow evaporator 7 , which can increase the heat exchange area without increasing the space occupied by the evaporator 7 , thereby helping to meet the refrigeration demand of the refrigeration equipment.

[0123] In some embodiments of the present application, the evaporator 7 is made of a copper tube or an aluminum tube.

[0124] Specifically, the aluminum tube evaporator 7 has good thermal conductivity, light weight, convenient processing, wide material sources, low price, low manufacturing cost, stable chemical properties, and is not easy to rust;

[0125] The copper tube evaporator 7 has better thermal conductivity because copper has excellent thermal conductivity, which allows the copper tube to quickly transfer heat and quickly dissipate the heat of the refrigerant medium, thereby improving the refrigeration efficiency. In addition, copper has good corrosion resistance. However, the price of copper is relatively high, which results in a high manufacturing cost of the copper tube as the evaporator 7. The specific form of the evaporator 7 can be set according to actual needs.

[0131] The refrigeration liner 4 is arranged below the freezing liner 1, and a refrigeration chamber 41 is formed therein;

[0132] The second partition 413 is disposed in the refrigerating chamber 41 to divide the refrigerating chamber 41 into a refrigerating air supply passage 411 and a refrigerating storage chamber 412. The refrigerating air supply passage 411 is located between the second partition 413 and the rear side wall of the refrigerating liner 4.
