Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] ‌A refrigerator is a refrigeration device used to maintain a constant low temperature, mainly used to preserve food and other items. ‌A refrigerator achieves low temperatures and provides storage space by changing the physical state of the refrigerant. Considering that different foods have different storage temperature requirements, the storage compartments inside the refrigerator are usually designed with a freezer compartment, a refrigerator compartment, and a variable temperature chamber. An evaporator assembly is installed in the freezer compartment, which is used to generate cold air to provide the low-temperature storage environment required for the freezer compartment, the refrigerator compartment, and the variable temperature chamber. Among them, the freezer compartment sends cold air into the variable temperature chamber through the air supply port.

[0003] However, in actual use, since the cold air entering the variable temperature room through the air supply port is directly blown to the side of the variable temperature room drawer near the air supply port, the temperature of the area near the air supply port in the variable temperature room drawer will be relatively low, causing the food in this area to freeze. The area far from the air supply port in the variable temperature room drawer is less affected by the cold air and therefore has a relatively high temperature, causing the food in this area to not freeze but to deteriorate, resulting in uneven temperature in the variable temperature room, affecting the performance and reliability of the refrigerator. Summary of the invention

[0066] See also Figure 1 , is a refrigerator 100 shown in an embodiment of the present application, which can specifically be any one of a single-door refrigerator, a double-door refrigerator, etc.

[0067] Please continue reading Figures 1 to 6 Exemplarily, the refrigerator 100 includes a housing 10 , a partition member 20 , a temperature-changing temperature drawer 30 , an evaporator assembly 40 , and an air guide plate 50 .

[0068] The box body 10 is in a rectangular parallelepiped shape, and thus has a height direction (i.e., length direction), a width direction (i.e., left-right direction), and a depth direction (i.e., thickness direction). The height direction of the box body 10 is set in a vertical direction perpendicular to the ground, and the width direction and the depth direction are both set in a horizontal plane parallel to the ground.

[0069] The partition member 20 is arranged in the box body 10 to separate the inner cavity of the box body 10 into a left compartment and a right compartment. In addition, a freezing chamber 11 and a temperature-changing chamber 12 are formed inside the box body 10. For example, in the present application, the freezing chamber 11 is arranged in the left compartment, and the temperature-changing chamber 12 is arranged in the right compartment. It is easy to understand that the freezing chamber 11 and the temperature-changing chamber 12 are arranged in the width direction of the box body 10.

[0070] Of course, the freezing chamber 11 may also be arranged in the right room, and the temperature-changing chamber 12 may also be arranged in the left room.

[0071] The partition member 20 is provided with an air supply port 21, and the freezing chamber 11 is connected to the temperature-changing chamber 12 through the air supply port 21. The partition member 20 can be integrally formed with the box body 10, or can be detachably assembled with the box body 10. In the present application, the partition member 20 and the box body 10 are integrally formed to obtain better structural performance and connection strength.

[0072] The temperature-changing chamber drawer 30 is installed inside the temperature-changing chamber 12. More specifically, the temperature-changing chamber drawer 30 can be pulled and moved in the temperature-changing chamber 12. When the temperature-changing chamber drawer 30 is pulled out from the temperature-changing chamber 12, it is convenient to take and put food from the temperature-changing chamber drawer 30.

[0073] In order to improve the installation stability of the variable temperature room drawer 30 and the moving smoothness during the pulling and pulling movement, a slide is formed on the side wall of the variable temperature room 12, and the slide is slidably installed with the variable temperature room drawer 30.

[0074] The evaporator assembly 40 is arranged in the evaporator chamber at the rear of the freezer chamber 11, and the evaporator assembly 40 is used to generate cold air; the air guide plate 50 is installed at the air supply port 21, and the air guide plate 50 has a plurality of air guide ports, which are used to guide the cold air to flow to different areas of the variable temperature room 12 respectively to achieve cooling of the variable temperature room drawer 30.

[0075] It is easy to understand that the multiple air guide vents are respectively arranged toward different areas of the variable temperature chamber 12 .

[0076] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: when the refrigerator 100 of this solution is working, the evaporator assembly 40 is started and generates cold air, and the cold air fills the freezing chamber 11 to create a low-temperature storage environment, thereby realizing the frozen storage of food; since the partition member 20 located between the freezing chamber 11 and the variable temperature chamber 12 is provided with an air supply port 21, the cold air can flow from the freezing chamber 11 through the air supply port 21 into the variable temperature chamber 12 to meet the need of creating a low-temperature environment in the variable temperature chamber 12; on this basis, by installing an air guide plate 50 at the air supply port 21, and then opening a plurality of air guide ports on the air guide plate 50, and making the air guide ports face different air spaces of the variable temperature chamber 12 respectively The cold air is arranged in an intermediate orientation, so that the cold air flowing in from the air supply port 21 can flow to different areas in the variable temperature chamber 12 respectively through the guiding effect of the multiple air guide ports, so that the cold air flows around the periphery of the variable temperature chamber drawer 30 to cool the variable temperature chamber 30; in this way, the cold air is distributed more evenly in the variable temperature chamber 12, and different parts of the variable temperature chamber drawer 30 can effectively contact the cold air, thereby ensuring that the temperature of the variable temperature chamber drawer 30 is uniform, so that the food stored in the variable temperature chamber drawer 30 can be effectively refrigerated, effectively solving the problem of food freezing in the area near the air supply port 21 and food spoiling in the area far from the air supply port 21, thereby improving the performance and reliability of the refrigerator 100.

[0077] Please continue reading Figure 2 On the basis of the above embodiment, a refrigerating chamber 13 is further formed inside the box body 10 , and the refrigerating chamber 13 is located above the temperature changing chamber 12 .

[0078] An air supply hole is also provided on the partition member 20, and the air supply hole is located at the back wall of the refrigerating chamber 13. The air supply hole connects the evaporator chamber where the evaporator assembly 40 in the freezing chamber 11 is located with the refrigerating chamber 13, so that the cold air generated in the evaporator chamber enters the refrigerating chamber 13 through the air supply hole, thereby creating the required low temperature environment in the refrigerating chamber 13.

[0079] In addition, the partition member 20 is also provided with a return air port 22 , and the cold air can circulate in the refrigerating chamber 13 and then return to the bottom of the evaporator chamber where the evaporator assembly 40 is located through the return air port 22 .

[0080] The refrigerator 100 further includes a refrigerator door 60 and a temperature-changing chamber partition 70. The refrigerator door 60 is openably mounted on the cabinet 10. For example, the refrigerator door 60 is rotatably mounted on the cabinet 10 via a hinge, and the cabinet 10 is opened or closed by rotating.

[0081] The variable temperature chamber partition 70 is arranged on the inner wall of the box body 10 and is located between the refrigerating chamber 13 and the variable temperature chamber 12; wherein, the inner wall of the box body 10 is provided with a box liner 14, and the inner wall of the refrigerator door 60 is provided with a door liner 61, and the door liner 61, the box liner 14 and the variable temperature chamber partition 70 together enclose the variable temperature chamber 12.

[0082] Compared with the traditional technology in which the variable temperature chamber 12 is usually assembled and enclosed by plastic parts and foam parts to form a sealed cavity, there is a serious waste of space, which results in the size of the variable temperature chamber drawer 30 having to be reduced, the installation and positioning of plastic parts and foam parts are difficult, and it is easy to cause structural abnormalities in the variable temperature chamber 12, and the cost is high. In this solution, the variable temperature chamber 12 is directly formed by enclosing the door liner 61, the box liner 14 and the variable temperature chamber partition 70, so that the molding method and structure of the variable temperature chamber 12 are simple, which well solves the problems existing in the above-mentioned traditional technology.

[0083] More specifically, in the present application, the variable temperature chamber 12 is separated from the refrigerating chamber 13 by a variable temperature chamber partition 70, so that the molding of the variable temperature chamber 12 is simpler and the design and manufacturing cost is reduced.

[0084] Usually, the temperatures of the freezing chamber 11, the refrigerating chamber 13 and the temperature-changing chamber 12 are different. The freezing chamber 11 has the lowest temperature (usually in the range of -18 to -24 degrees), the temperature of the temperature-changing chamber 12 is the second lowest (in the range of -1 to 6 degrees), and the temperature of the refrigerating chamber 13 is the highest (usually in the range of 0-10 degrees). Therefore, how to reduce the temperature conduction between the chambers is the key to ensure that each chamber is maintained within the required temperature range.

[0085] Please continue reading Figure 4 Based on the above, in one embodiment, the temperature-changing chamber partition 70 includes a first plate 72, a heat-insulating layer 73 and a second plate 74, and the heat-insulating layer 73 is stacked between the first plate 72 and the second plate 74. The first plate 72 and the second plate 74 sandwich the heat-insulating layer 73 in the middle, so that the temperature-changing chamber partition 70 has a stable structure; the heat-insulating layer 73 has excellent heat-insulating capacity, which can prevent the cold from being conducted between the refrigerating chamber 13 and the temperature-changing chamber 12, and ensure the temperature stability in the refrigerating chamber 13 and the temperature-changing chamber 12.

[0086] Optionally, the heat insulating layer 73 can be any one of foam, PE cotton, etc. In the present application, considering that the thinnest thickness of the foam needs to be at least 10 mm, PE cotton is preferably used from the perspective of saving volume, which can solve the problems of heat insulation, space saving and cost reduction at the same time.

[0087] The key to achieving uniform temperature in the variable temperature chamber 12 of the present invention is that the cold air flowing into the variable temperature chamber 12 from the air supply port 21 can be evenly distributed and flow in various areas in the variable temperature chamber 12, so that the variable temperature chamber drawer 30 can be evenly exposed to the cold air, ensuring that the temperature drop of the food stored in the variable temperature chamber drawer 30 is uniform.

[0088] Please continue reading Figure 3 ,as well as Figures 7 to 10 In an optional embodiment, the temperature-changing drawer 30 includes a drawer bottom surface 31 , a drawer rear side surface 32 and a drawer top surface 33 ; the box liner 14 includes an liner bottom surface 141 and an liner rear side surface 142 .

[0089] The drawer bottom surface 31 cooperates with the inner container bottom surface 141 to form a first flow channel 80, the drawer rear side surface 32 cooperates with the inner container rear side surface 142 to form a second flow channel 80a, and the drawer top surface 33 cooperates with the variable temperature chamber partition 70 to form a third flow channel 80b.

[0090] It is easy to understand that the first flow channel 80 is formed by the gap between the drawer bottom surface 31 and the inner tank bottom surface 141, the second flow channel 80a is formed by the gap between the drawer rear side surface 32 and the inner tank rear side surface 142, and the third flow channel 80b is formed by the gap between the drawer top surface 33 and the variable temperature room partition 70.

[0091] Please continue reading Figure 8 , Fig.10 , Figure 12 to Figure 13 The plurality of air guide ports include a first air guide port 51, a second air guide port 52 and a third air guide port 53. The first air guide port 51 is connected to the first flow channel 80, the second air guide port 52 is connected to the second flow channel 80a, and the third air guide port 53 is connected to the third flow channel 80b.

[0092] Therefore, the cold air delivered to the air guide plate 50 from the air supply port 21 will be divided into three streams of cold air. The three streams of cold air respectively enter the first flow channel 80 from the first air guide port 51, enter the second flow channel 80a from the second air guide port 52, and enter the third flow channel 80b from the third air guide port 53. The three streams of cold air flow through the bottom, rear side and top surface of the variable temperature room drawer 30 at the same time, so that the cold air can be evenly distributed in the variable temperature room 12, and then the food in the variable temperature room drawer 30 is evenly cooled by the cold air, thereby ensuring that the temperature in the variable temperature room drawer 30 is uniform, the food is well preserved, and the spoilage of food caused by excessive local temperature is avoided.

[0093] Furthermore, the variable temperature room drawer 30 also includes a first drawer side 34 arranged away from the air supply port 21, and a drawer front side 35 arranged opposite to the drawer rear side 32, and the box liner 14 also includes a first liner side 143 connected between the liner bottom surface 141 and the liner rear side 142.

[0094] The first drawer side surface 34 cooperates with the first inner container side surface 143 to form a fourth flow channel 80c, and the fourth flow channel 80c is connected to the first flow channel 80, the second flow channel 80a and the third flow channel 80b.

[0095] The partition member 20 is also provided with a return air port 22 , and the drawer front side surface 35 cooperates with the door liner 61 to form a return air flow channel 80 d , and the return air flow channel 80 d is connected to the fourth flow channel 80 c and the return air port 22 , and the return air port 22 is connected to the freezer chamber 11 .

[0096] The cold air flowing through the first flow channel 80, the second flow channel 80a and the second flow channel 80a will first converge in the fourth flow channel 80c to form a return cold air, and then the return cold air will change direction and flow into the return air flow channel 80d formed by the gap between the front side surface 35 of the drawer and the door liner 61, and then directly flow to the return air port 22 preset on the partition member 20, and finally flow into the freezer 11 through the return air port 22, thereby forming a cold air circulation flow path. The flow path of the cold air in the variable temperature chamber 12 is unobstructed and optimized, and the cold air in different flow channels will not conflict with each other to cause eddy currents, thereby improving the quietness of the refrigerator 100, and the cold air flows into and out of the variable temperature chamber 12 smoothly and efficiently, which helps to improve the refrigeration effect.

[0097] It should be noted that the above-mentioned return air vent 22 is the return air vent 22 originally belonging to the refrigerating chamber 13. In this solution, since the variable temperature chamber 12 is separated from the refrigerating chamber 13, it is only necessary to move the return air vent 22 upward to a certain position so that the return air vent 22 is above the variable temperature chamber 12 and at the same time located at the bottom of the refrigerating chamber 13. At this time, the cold air in the refrigerating chamber 13 and the cold air in the variable temperature chamber 12 both flow back to the freezing chamber 11 through the return air vent 22. There is no need to increase the number of return air vents 22, reduce the structure, and reduce the manufacturing cost.

[0098] Please continue reading Fig.11 Furthermore, the temperature-changing room drawer 30 also includes a second drawer side 36 arranged toward the air supply port 21, one of the first drawer side 34 and the second drawer side 36 is provided with an air inlet hole 341, and the other of the first drawer side 34 and the second drawer side 36 is provided with an air outlet hole 361.

[0099] In addition to being connected to the internal cavity of the temperature-changing temperature drawer 30, the air inlet hole 341 and the air outlet hole 361 also need to be connected to each flow channel. Therefore, when the cold air flows through each flow channel, a small amount of cold air will flow into the internal cavity of the temperature-changing temperature drawer 30 through the air inlet hole 341 and then flow out from the air outlet hole 361, so that this part of the cold air can better contact the food stored inside, so that the temperature of the food is evenly reduced, thereby improving energy utilization and utilization effect.

[0100] Please continue reading Fig.10 In addition, based on any of the above embodiments, the box liner 14 also includes a second liner side 144 arranged opposite to the first liner side 143, the first liner side 143 is provided with a first sealing slot 143a extending along the depth direction of the refrigerator 100, and the second liner side 144 is provided with a second sealing slot 144a extending along the depth direction of the refrigerator 100.

[0102] On the one hand, by plugging the first side into the first sealing slot 143a and the second side into the second sealing slot 144a, the variable temperature chamber partition 70 can be stably installed, and the installation method is simple. Compared with installation methods such as screwing and bonding, threaded parts, glue and other auxiliary materials can be omitted, thereby reducing costs and installation difficulty. On the other hand, the three-sided sealed installation structure can also realize the sealed assembly between the variable temperature chamber partition 70 and the box liner 14, preventing the cold from being conducted between the refrigerating chamber 13 and the variable temperature chamber 12, maintaining the respective temperature environments in the refrigerating chamber 13 and the variable temperature chamber 12, and being more conducive to the storage of different foods.

[0103] Furthermore, a positioning hole 142a is concavely formed on the rear side surface 142 of the inner container, and a positioning protrusion 71 is formed on the third side of the variable temperature chamber partition 70, and the positioning protrusion 71 is inserted into the positioning hole 142a. The positioning protrusion 71 is inserted into the positioning hole 142a to form a positioning structure, which improves the installation stability and position accuracy of the variable temperature chamber partition 70, and can well limit the vertical deviation of the variable temperature chamber partition 70.

[0105] The mounting base plate 54 is mounted on the partition member 20 to realize the integral mounting and fixing of the air guide plate 50 to the partition member 20. The mounting method can be at least one of screw connection, clamp connection, magnetic connection, bonding, etc., which can be flexibly selected according to actual needs.

[0106] The mounting base plate 54 is provided with an air inlet which is in communication with the air supply port 21 so as to allow cold air to enter the air guide plate 50 through the air inlet.

[0107] The wind shield 55 and the mounting base plate 54 are arranged side by side and spaced apart, and the wind shield 55 is located between the mounting base plate 54 and the second drawer side 36; the first plate body 56, the second plate body 57 and the third plate body 58 are connected end to end between the mounting base plate 54 and the wind shield 55, the first plate body 56 is provided with a first air guide port 51, the second plate body 57 is provided with a second air guide port 52, and the third plate body 58 is provided with a third air guide port 53.

[0109] Optionally, the first plate 56, the second plate 57 and the third plate 58 are all inclined with respect to the wind shield 55, and the angles between the first plate 56, the second plate 57 and the third plate 58 and the wind shield 55 are all 22° to 24°. The cold air flow path is simulated by simulation software, and it is found that when the inclination angle is within the range of 22° to 24°, the cold air flowing out of the first air guide port 51, the second air guide port 52 and the third air guide port 53 has good directivity, and the cold air can flow directly into the first flow channel 80, the second flow channel 80a and the third flow channel 80b more accurately, thereby ensuring the effectiveness of the cold air flow.

[0110] Preferably, in the present application, the angles between the first plate 56 , the second plate 57 , and the third plate 58 and the wind shield 55 are all 20°.

[0111] Furthermore, according to simulation and experimental results, there is an optimal ratio among the opening areas of the first air guide port 51, the second air guide port 52 and the third air guide port 53 to ensure smooth flow of cold air in different flow channels, which is beneficial to uniform temperature distribution and avoids eddy currents.

[0112] The opening area of ​​the first air guide port 51 is 500 mm 2 ~700mm 2 The opening area of ​​the second air guide port 52 is 170 mm 2 ~370mm 2 The opening area of ​​the third air guide port 53 is 600 mm 2 ~800mm 2 For example, a preferred implementation ratio is that the opening area of ​​the first air guide port 51 is 600 mm 2 The opening area of ​​the second air guide port 52 is 270 mm 2 The opening area of ​​the third air guide port 53 is 700 mm 2 .

[0114] Furthermore, the air guide plate 50 further includes a shielding plate 59, which is connected between the mounting base plate 54, the air shielding plate 55, the first plate body 56 and the third plate body 58, and is disposed toward the return air passage 80d. The shielding plate 59 is used to prevent the cold air from flowing back into the return air passage 80d and causing vortex phenomenon.

[0115] Please continue reading Figure 3 , Figures 4 to 10 In addition, based on any of the above embodiments, the refrigerator 100 further includes a temperature sensor 90, which is disposed on the first inner liner side 143, and a control panel is disposed on the refrigerator door 60, and the control panel is electrically connected to the temperature sensor 90. The temperature sensor 90 can monitor the temperature value in the variable temperature chamber 12 in real time, and transmit the temperature data to the control panel for display, so that the user can intuitively monitor the temperature of the variable temperature chamber 12. When the temperature is abnormal, the temperature can be adjusted in time through the control panel.

[0116] Please continue reading Figure 4 , Figure 5 and Fig.10In addition, the refrigerator 100 further includes an electric damper 90a, which is installed at the air outlet 21 and is electrically connected to the control panel. The electric damper 90a is used to adjust the opening size of the air outlet 21. When the temperature sensor 90 detects that the temperature in the variable temperature chamber 12 is too high, the user operates the control panel to control the electric damper 90a through the control panel to increase the opening of the air outlet 21, thereby increasing the flow of cold air flowing into the variable temperature chamber 12, thereby achieving temperature reduction regulation of the variable temperature chamber 12; otherwise, the variable temperature chamber 12 can be heated up. The temperature in the variable temperature chamber 12 is well controllable and the temperature regulation is highly accurate, which is conducive to ensuring that the variable temperature chamber 12 is in the best temperature environment.

[0117] In addition, another embodiment of the present application further provides a refrigerator 100, which includes a box body 10; a partition member 20, which is located inside the box body 10 and is used to divide the box body 10 into compartments distributed on the left and right; a freezer compartment 11, which is located on one side of the partition member 20; a refrigerating compartment 13 and a variable temperature chamber 12, which are located on the other side of the partition member 20 and are arranged opposite to the freezer compartment 11, and the variable temperature chamber 12 is located at the lower part of the refrigerating compartment 13; an evaporator assembly 40, which is located in the evaporator chamber at the rear of the freezer compartment 11, and is used to generate cold air and blow it into the refrigerating compartment 13, and then The return air port 22 on the partition member 20 is blown into the evaporator chamber; the evaporator assembly 40 is also used to generate cold air and blow it into the freezing chamber 11, and then blow it into the evaporator chamber through the freezing chamber 11; the air supply port 21 is located on the partition member 20 between the freezing chamber 11 and the variable temperature chamber 12, and is used to connect the freezing chamber 11 and the variable temperature chamber 12; the air guide plate 50 is installed at the air supply port 21, and is used to allow the cold air generated by the evaporator assembly 40 to pass through the freezing chamber 11, blown into the variable temperature chamber 12 through the air supply port 21, cool the variable temperature chamber 12, and then blown into the evaporator chamber through the return air port 22.

[0118] In this way, the cold air generated by the evaporator assembly 40 in the evaporator chamber can meet the needs of air supply to the refrigerating chamber 13 and the variable temperature chamber 12, respectively, so that the refrigerating chamber 13 and the variable temperature chamber 12 can respectively create the required low-temperature refrigeration environment, and realize the storage of different foods and other items. At the same time, by setting the return air port 22, a cold air return path is formed, so that each room can obtain a better cooling effect.
