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 upper freezing and lower storage, the evaporator is usually set at 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 heat absorption and evaporation, thereby reducing the temperature of the evaporator and providing a cold source for refrigerator refrigeration. However, if the evaporator is set at the back of the freezer, the longitudinal depth of the freezer compartment will be reduced, thereby reducing the usable volume of the freezer compartment and reducing the user experience. In addition, after the refrigerator has been running for a long time, frost will form on the evaporator, and the water generated during the defrosting process of the refrigerator is difficult to be discharged from the box in time, which will cause bacteria to grow and pose a certain threat to the food hygiene in the refrigerator. In view of this, how to design a technology that can discharge the water from the refrigerator during the defrosting process in time and increase the usable volume of the refrigerator to improve the user experience is the technical problem to be solved by the utility model.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0063] 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.

[0064] 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 tank 1, a freezing door body, a drain pipe 122, a partition assembly 2, a refrigeration tank 3, a refrigeration door body, and a refrigeration system.

[0065] Combination Figure 1 As shown, the freezing liner 1 and the refrigerating liner 3 are both arranged in the outer shell, and the refrigerating liner 3 is arranged below the freezing liner 1. The front ends of the freezing liner 1 and the refrigerating liner 3 are respectively provided with openings for taking out and placing frozen food and refrigerated food, and the freezing door body is openably arranged at the opening of the freezing liner 1, and the refrigerating door body is openably arranged at the opening of the refrigerating liner 3.

[0066] A freezing chamber 11 is formed inside the freezing liner 1, and a partition assembly 2 is arranged at the lower part of the freezing chamber 11. The partition assembly 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, 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 air supply port 221 and a freezing air return port 211 are formed on the partition assembly 2, and the freezing air supply port 221 and the freezing air return port 211 respectively connect the refrigerating chamber 112 and the freezing chamber 111, and the freezing air supply port 221 is used for the refrigerating chamber 112 to convey cold air to the freezing chamber 111, and the freezing air return port 211 is used for the freezing chamber 111 to convey air that has undergone heat exchange with the medium in the freezing chamber 111 to the refrigerating chamber 112. The refrigeration chamber 112 , the freezing air supply port 221 , the freezing chamber 111 , the freezing air return port 211 , and the refrigeration chamber 112 are sequentially connected to form an air refrigeration circulation loop in the freezing chamber 11 .

[0067] A refrigeration chamber 31 is formed in the refrigeration liner 3, and the refrigeration chamber 31 is used to refrigerate and preserve food; the refrigeration chamber 31 is connected to the refrigeration chamber 112 through the refrigeration air supply port 41 and the refrigeration return air port 51; the refrigeration air supply port 41 and the refrigeration return air port 51 are respectively arranged at the lower part of the freezing liner 1 and the top of the refrigeration liner 3. The refrigeration air supply port 41 and the refrigeration return air port 51 respectively connect the refrigeration chamber 112 with the refrigeration chamber 31. Among them, the refrigeration air supply port 41 is used for the refrigeration chamber 112 to transport cold air to the refrigeration chamber 31, and the refrigeration return air port 51 is used for the refrigeration chamber 31 to transport gas for heat exchange with the medium in the refrigeration chamber 31 to the refrigeration chamber 112. The refrigeration chamber 112, the refrigeration air supply port 41, the refrigeration chamber 31, the refrigeration return air port 51, and the refrigeration chamber 112 are connected in sequence to form an air refrigeration circulation loop in the refrigeration chamber 31.

[0068] It should be noted that, since the refrigerating liner 3 and the freezing liner 1 are independently provided, and the refrigerating chamber is located at the bottom of the freezing liner 1 , a refrigerating air supply port 41 and a refrigerating air return port 51 are provided in the refrigerating liner 3 and the freezing liner 1 , respectively.

[0069] In some embodiments, one of the refrigerated air supply vents 41 is located at the lower portion of the rear side wall of the freezing inner container 1 , and the other refrigerated air supply vent 41 is located at the upper portion of the rear side wall of the refrigerated inner container 3 .

[0070] In other embodiments, one of the refrigerated air supply vents 41 is located on the bottom wall of the freezing inner container 1 , and the other refrigerated air supply vent 41 is located on the top wall of the refrigerated inner container 3 .

[0071] Combination Figure 2 , Figure 3 and Figure 4 As shown in some embodiments of the present application, the refrigeration device further includes a refrigerated air supply unit 4 and a refrigerated air return unit 5 .

[0072] The refrigerated air supply unit 4 and the refrigerated air return unit 5 are both located between the freezing liner 1 and the refrigerating liner 3, and are both used to connect the refrigerating chamber 112 and the refrigerating chamber 31, wherein the refrigerated air supply port 41 is located on the refrigerated air supply unit 4, and the refrigerated return air port 51 is located on the refrigerated return air unit 5.

[0073] Combination Figure 2 and Figure 5 As shown, in some other embodiments of the present application, the refrigerated air supply unit 4 and the refrigerated air return unit 5 are both flat tube structures.

[0074] The refrigerated return air portion 5 is arranged along the width direction of the freezing inner container 1, which can enhance the circulation efficiency of the refrigerated air duct. While improving the return air efficiency, the problem of uneven frosting on the surface of the evaporator 6 can be improved.

[0075] In some embodiments of the present application, the refrigeration system includes a compressor, a condenser, a cooling fan, a throttling device, an evaporator 6 and a fan 7. The fan 7 and the evaporator 6 are both arranged in the refrigeration chamber 112.

[0076] The compressor, condenser, throttling device and evaporator 6 are connected by pipes 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 6. 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.

[0077] 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.

[0078] 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 6, which is arranged in the refrigeration chamber 112. In the evaporator 6, 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 6 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 31 and the freezer compartment 111 through the fan 7.

[0079] Combination Figure 6 and Figure 7As 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;

[0080] Usually, during the use of the evaporator 6, the evaporator 6 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 6 not only affects the efficiency of the refrigeration equipment, but also may cause damage to the equipment. Therefore, the evaporator 6 needs to be defrosted regularly.

[0081] After defrosting, the frost layer of the evaporator 6 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 6 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 refrigeration chamber 31.

[0082] The fan 7 is configured to deliver the cold air in the refrigeration chamber 112 into the freezing chamber 111 through the freezing air supply port 221, and to suck the air in the freezing chamber 111 into the refrigeration chamber 112 through the freezing air return port 211; and to deliver the cold air in the refrigeration chamber 112 into the cold storage chamber 31 through the cold storage air supply port 41, and to suck the air in the cold storage chamber 31 into the refrigeration chamber 112 through the cold storage air return port 51.

[0083] Specifically, the partition assembly 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 3 is arranged below the freezing liner 1. A refrigerating chamber 31 is formed in the refrigerating liner 3. The refrigerating chamber 31 is connected to the refrigerating chamber 112 through a refrigerating air supply port 41 and a refrigerating air return port 51. The fan 7 and the evaporator 6 are arranged in the refrigerating chamber 112. The fan 7 can send the cold air in the refrigerating chamber 112 into the freezing chamber 111 and the refrigerating chamber 31 respectively, and suck the air in the freezing chamber 111 and the refrigerating chamber 31 into the refrigerating chamber 112. The fan 7 and the evaporator 6 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 increasing the usable volume of the refrigerator and enhancing the user experience.

[0084] In some embodiments of the present application, the evaporator 6 and the bottom wall of the freezing container 1 have a consistent inclination angle.

[0085] Specifically, by setting the evaporator 6 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.

[0086] On the other hand, combined Fig.11 As shown, 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 6 to form a thin water film. By tilting the evaporator 6, the water on the surface of the evaporator 6 can be quickly dripped, reducing the formation of the water film on the surface of the evaporator 6, so that the evaporator 6 can work more stably.

[0087] Combination Fig. 9 As shown, in some embodiments of the present application, the bottom wall of the evaporator 6 and the freezing container 1 are inclined at an angle α to the horizontal direction, 2°≤α≤10°.

[0088] Exemplarily, the inclined angle α between the evaporator 6 and the bottom wall of the freezing container 1 and the horizontal direction is 5°, 6°, 7° or 8°.

[0089] 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 3.

[0090] 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 3, and the drain pipe 122 is located on the rear side of the refrigeration tank 3, and the temperature of the refrigeration tank 3 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.

[0091] After the refrigeration equipment has been used for a period of time, frost will usually appear on the evaporator 6. 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 6. 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.

[0092] In some embodiments of the present application, the refrigeration device further includes a defrost heater 8 .

[0093] The defrost heater 8 is connected to the evaporator 6 and is located below the evaporator 6 . The defrost heater 8 is configured to remove frost on the evaporator 6 .

[0094] Specifically, a slot is formed on the evaporator 6, and the slot is used to fix the defrost heater 8. By arranging the defrost heater 8, the frost on the evaporator 6 can be melted to keep the inside of the refrigeration device dry and clean.

[0095] In some embodiments of the present application, the refrigerated return air inlet 211 and the refrigerated return air inlet 51 are located on the front side of the evaporator 6, the refrigerated supply air inlet 221 and the refrigerated supply air inlet 41 are located on the rear side of the evaporator 6, and the defrost heater 8 is densely arranged near the refrigerated return air inlet 211 than far away from the refrigerated return air inlet 211.

[0096] Specifically, since the refrigerated air supply port 221 and the refrigerated air supply port 41 are located on the rear side of the evaporator 6, and the refrigerated return air port 211 and the refrigerated return air port 51 are located on the front side of the evaporator 6, the front end of the evaporator 6 is more severely frosted. By arranging the defrost heaters 8 more densely near the refrigerated return air port 211 than far away from the refrigerated return air port 211, defrosting can be performed faster, thereby improving the defrosting efficiency of the refrigeration equipment.

[0097] In some embodiments of the present application, the evaporator 6 includes a fin-type evaporator 6 or a parallel-flow evaporator 6 .

[0098] Specifically, the evaporator 6 adopts a finned evaporator 6 or a parallel flow evaporator 6, which can increase the heat exchange area without increasing the space occupied by the evaporator 6, which is conducive to meeting the refrigeration demand of the refrigeration equipment.

[0099] In some embodiments of the present application, the evaporator 6 is made of a copper tube or an aluminum tube.

[0100] Specifically, the aluminum tube evaporator 6 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;

[0101] The copper tube evaporator 6 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 6.
