Technical Field
[0001] The utility model relates to the technical field of refrigerators, in particular to an embedded refrigerator. Background Art
[0002] In order to appear concise and beautiful, more and more families choose embedded refrigerators that are embedded in the cabinet and do not occupy external space. However, since the embedded refrigerator is installed in the cabinet, if it adopts the conventional heat dissipation scheme at the rear of the refrigerator, the heat will be concentrated in the cabinet and cannot be dissipated. Therefore, the embedded refrigerator usually adopts a bottom heat dissipation technical scheme, that is, ventilation openings are opened on the side walls of the compressor compartment at the bottom of the box body, and the heat in the compressor compartment is dissipated through the ventilation openings.
[0003] Since the air blown out through the ventilation opening has a high temperature, opening the refrigerator door at this time will cause the heat to enter the refrigerator interior and cause a rapid temperature rise, increasing the power consumption of the refrigerator in vain. And the air blown out for heat dissipation in the compressor compartment may carry dust and bacteria, which will bring the dust and bacteria into the refrigerator interior when the refrigerator door is opened, affecting the freshness preservation of food. Summary of the Utility Model

[0041] The present utility model provides an embedded refrigerator 100, which dissipates heat through a ventilation opening 111 formed on the side wall of a compressor compartment 11 at the bottom of a box body 10, and a blade 30 capable of blocking or opening the ventilation opening 111 in response to the opening and closing of a refrigerator door 20 is installed at the ventilation opening 111, preventing heat from entering the interior of the refrigerator and also reducing the entry of impurities such as bacteria and dust into the interior of the refrigerator.
[0042] Please refer to Figure 1 - Figure 2 , the embedded refrigerator 100 includes a box body 10, a refrigerator door 20, a blade 30 and a driving assembly 40. A compressor compartment 11 is formed at the bottom of the box body 10, a ventilation opening 111 is formed on the side wall of at least one side of the compressor compartment 11, a chamber 112 is constructed inside the compressor compartment 11, and the chamber 112 is communicated with the external environment through the ventilation opening 111; the refrigerator door 20 is rotatably connected to the box body 10, and the side of the box body 10 where the refrigerator door 20 is located is the front side, and the ventilation opening 111 is formed on the front side of the compressor compartment 11; the blade 30 is movably connected to the compressor compartment 11 and can rotate relative to the compressor compartment 11 to block or open the ventilation opening 111; the driving assembly 40 is installed inside the chamber 112 and connected to the blade 30, and is configured to close the ventilation opening 111 by the blade 30 in response to the opening of the refrigerator door 20, and open the ventilation opening 111 by the blade 30 in response to the closing of the refrigerator door 20.
[0043] Thus, the press chamber 11 at the bottom of the cabinet 10 is used to install heat-generating components such as a compressor. The ventilation openings 111 provided on the side walls of the press chamber 11 allow air to flow through, thereby taking away the heat in the press chamber 11 to complete the heat dissipation work. The ventilation openings 111 are provided on the front side of the press chamber 11, and the refrigerator door 20 is located on the front side of the cabinet 10. Therefore, it is convenient to perform linkage operations on the drive assembly 40 during the opening or closing process of the refrigerator door 20. When the refrigerator door 20 is opened, the space inside the refrigerator is in an open and exposed state. At this time, the drive assembly 40 drives the blade 30 to close the ventilation opening 111 in response to the state of the refrigerator door 20, preventing the hot air blown out from the ventilation opening 111 from entering the refrigerator interior, causing the temperature inside the refrigerator to rise, increasing the power consumption of components such as the refrigerator compressor for cooling, and also preventing the blown air from causing dust, bacteria, and impurities in the external environment to enter the refrigerator interior and affecting the preservation of food inside the refrigerator.
[0044] Specifically, at least a part of the press chamber 11 protrudes forward and extends to the vertical lower side of the refrigerator door 20 to form an installation space, and the blade 30 and the drive assembly 40 are located in the installation space. In this way, it is convenient to install the blade 30 and also facilitates the linkage with the refrigerator door 20.
[0045] Furthermore, the press chamber 11 includes a main chamber 115 and an installation chamber 116. The installation chamber 116 is connected to the front side of the main chamber 115, and the installation chamber 116 protrudes from the projection of the cabinet 10 in the vertical direction and extends to the lower side of the refrigerator door 20. In this way, the installation chamber 116 provides a space for installing the blade 30 and the drive assembly 40, fixes the blade 30 and the drive assembly 40, and can also keep the ventilation opening 111 away from the refrigerator interior, and try to keep the hot air blown out away from the cabinet 10.
[0046] The box body 10 includes a first box body 12 and a second box body 13 which are symmetrically arranged. There is a partition 14 between the first box body 12 and the second box body 13, and they are connected through the partition 14. The driving assembly 40 is located between the projections of the first box body 12 and the second box body 13 in the vertical direction. The built-in refrigerator 100 further includes a first rotating seat 15 and a second rotating seat 16. The first rotating seat 15 is located at the bottom of the first box body 12 and is arranged away from the second box body 13. The second rotating seat 16 is located at the bottom of the second box body 13 and is arranged away from the first box body 12. A blade 30 is arranged between the first rotating seat 15 and the driving assembly 40, and one end of the blade 30 is rotatably connected to the first rotating seat 15, and the other end is connected to the driving assembly 40. A blade 30 is arranged between the second rotating seat 16 and the driving assembly 40, and one end of the blade 30 is rotatably connected to the second rotating seat 16, and the other end is connected to the driving assembly 40. Thus, the ventilation openings 111 can be provided in two corresponding to the first box body 12 and the second box body 13, and the two ventilation openings 111 are respectively located on the vertical lower sides of the first box body 12 and the second box body 13. The blades 30 can also be correspondingly divided into two groups, and the two groups of blades 30 are installed at the ventilation openings 111 on the lower side of the first box body 12 and at the ventilation openings 111 of the second box body 13. The driving assembly 40 is located between the two groups of blades 30 and is connected to the two groups of blades 30 at the same time. Therefore, the driving assembly 40 can drive the two groups of blades 30 to rotate at the same time, which simplifies the structure and reduces the cost. If two driving assemblies 40 are provided, problems such as synchronism are likely to occur. The first rotating seat 15 and the second rotating seat 16 respectively fix the two ends of the two groups of blades 30 away from the driving assembly 40, so that the rotation of the two groups of blades 30 can be more stable and smooth.
[0047] Regarding the connection relationship and driving method between the driving assembly 40 and the blade 30, the present application provides two implementation manners, which are elaborated in detail one by one here.
[0048] Embodiment 1:
[0049] Please refer to Figure 3 - Figure 7, the driving component 40 includes a first magnet 41 and a sliding member 42. The sliding member 42 and the first magnet 41 are both arranged in the press chamber 11, and the sliding member 42 can move in the press chamber 11. The first magnet 41 is connected to the sliding member 42; a second magnet 21 is fixedly connected to the bottom of the refrigerator door 20, and the second magnet 21 and the first magnet 41 are set to be of the same polarity; the blade 30 is connected to the sliding member 42, and as the sliding member 42 moves downward, the blade 30 opens the ventilation opening 111. Thus, since the first magnet 41 and the second magnet 21 are of the same polarity, they repel each other when approaching. Therefore, when the refrigerator door 20 is closed (that is, when the refrigerator door 20 rotates to directly above the installation chamber 116 of the press chamber 11 and the second magnet approaches the first magnet 41), the first magnet 41 and the second magnet generate a movement tendency to move away from each other. Since the second magnet 21 is fixedly connected to the refrigerator door 20 and its position remains unchanged, the first magnet 41 moves downward along the direction away from the second magnet 21, thereby driving the sliding member 42 to move, and then driving the blade 30 to rotate and open the ventilation opening 111 through the sliding member 42.
[0050] Further, an installation groove 421 is formed at the top of the sliding member 42, and the first magnet 41 is installed in the installation groove 421. The installation groove 421 provides a space for installing the first magnet 41, and the first magnet 41 is arranged at the top of the sliding member 42, and it is relatively close to the second magnet installed at the bottom of the refrigerator door 20, and the repulsive force generated by the two is greater. Therefore, it is ensured that the repulsive force for the first magnet 41 to move downward is sufficient to drive the blade 30 to rotate.
[0051] A plurality of guide grooves 422 are formed on the sliding member 42. The plurality of guide grooves 422 are arranged at intervals along the vertical direction, and one end of each blade 30 respectively extends into the guide grooves 422. As the sliding member 42 moves in the vertical direction, the end of the blade 30 extending into the guide grooves 422 can move in the guide grooves 422 to open or close the ventilation opening 111. Thus, the first magnet 41 first drives the sliding member 42 to move along the vertical direction. While the sliding member 42 moves, through the abutting action between the guide grooves 422 and the blade 30, the blade 30 is driven to rotate. While the blade 30 rotates, it also moves from one end of the guide grooves 422 to the other end. The plurality of guide grooves 422 can drive the plurality of blades 30 to move simultaneously, that is, the ventilation opening 111 is blocked or opened through the opening and closing of the plurality of blades 30. Its opening and closing efficiency is high, and the opening force required for each blade 30 is also small.
[0052] A guide plate 113 is further arranged in the chamber 112. The guide plate 113 is fixedly connected to the inner wall of the press chamber 11 and extends along the vertical direction. The sliding member 42 abuts against the guide plate 113 and moves along the extending direction of the guide plate 113.
[0053] In this way, the guiding plate 113 can guide the moving direction of the sliding member 42, making the movement process of the sliding member 42 more linear and stable, and making the rotation of the blade 30 more stable.
[0054] The blade 30 includes a main body portion 31 and a fitting portion 32, and the fitting portion 32 is connected to the main body portion 31; a plurality of positioning grooves 1131 are formed in the guiding plate 113, each positioning groove 1131 corresponding to a guiding groove 422. One end of the fitting portion 32 close to the main body portion 31 is located in the positioning groove 1131 and can rotate in the positioning groove 1131, and the other end extends into the guiding groove 422. In this way, the main body portion 31 of the blade 30 is specifically used to close the ventilation hole and block the air flow, while the fitting portion 32 is used to cooperate with the guiding plate 113 and the sliding member 42 to guide the rotation of the main body portion 31. At the same time, since the positioning grooves 1131 on the guiding plate 113 correspond to the guiding grooves 422 on the sliding member 42 one by one, the rotation of the fitting portion 32 is limited by both of them at the same time, ensuring that the rotation path of the fitting portion 32 is more consistent, that is, making the rotation of the main body portion 31 of the blade 30 more stable.
[0055] Furthermore, the fitting portion 32 includes a fitting section 321 and a limiting section 322. The fitting section 321 is located at both ends of the limiting section 322. One fitting section 321 is located in the positioning groove 1131, and the other fitting section 321 extends into the guiding groove 422. The limiting section 322 is located between the guiding plate 113 and the sliding member 42, and as the fitting section 321 rotates, the limiting section 322 abuts against the inner wall of the press chamber 11. In this way, the two ends of the fitting section 321 cooperate with the positioning groove 1131 and the guiding groove 422 respectively, and the two force application points are spaced apart by a certain distance, enabling the two ends of the fitting portion 32 to be respectively subjected to limiting forces, which can improve the guiding and limiting effects on the fitting portion 32, and the abutment of the limiting section 322 against the inner wall of the press chamber 11 can prevent the blade 30 from rotating excessively.
[0056] The driving assembly 40 further includes a first elastic member 43. The first elastic member 43 is located at the bottom of the sliding member 42, and one end of the first elastic member 43 abuts against the sliding member 42, and the other end abuts against the inner bottom wall of the press chamber 11. In this way, after the first elastic member 43 separates the first magnet and the second magnet, the first magnet can return to its initial position, causing the sliding member 42 to move upward, thereby driving the blade 30 to rotate to close the ventilation opening 111.
[0057] In this embodiment, the first elastic member 43 is a spring, and in other embodiments, elastic rubber or other structures can also be used.
[0058] Compared with the prior art, the solution adopted in the first embodiment enables the sliding member 42 to move downward by means of magnetic repulsive force to open the blade 30 when the refrigerator door 20 approaches, and move upward by means of the first elastic member 43 to close the blade 30 when the refrigerator door 20 moves away, in response to the rotation of the refrigerator door 20 through the repulsive force between the first magnet and the second magnet. Its structure is simple, the linkage effect is good, and the magnetic repulsive force does not generate physical friction, extending the service life of the device.
[0059] Embodiment 2:
[0060] Please refer to Figure 8 - Figure 15 , a fixed seat 114 is arranged in the press chamber 11, the fixed seat 114 is fixedly connected to the inner wall of the press chamber 11, the driving assembly 40 includes a connecting rod 45 and a moving member 46, the connecting rod 45 is rotatably connected to the fixed seat 114 and partially extends out of the upper side wall of the press chamber 11, the part of the connecting rod 45 located in the chamber 112 is connected to the moving member 46, and the moving member 46 is connected to the blade 30; as the refrigerator door 20 closes, the refrigerator door 20 abuts against one end of the connecting rod 45 extending out of the press chamber 11 and drives the connecting rod 45 to rotate, so as to drive the blade 30 to open through the moving member 46. In this way, the connecting rod 45 is rotatably connected to the fixed seat 114 and can rotate relative to the fixed seat 114. Since the connecting rod 45 partially extends out of the upper side wall of the press chamber 11, when the refrigerator door 20 rotates towards the box body 10 and closes, the refrigerator door 20 abuts against the upper end of the connecting rod 45, drives the connecting rod 45 to rotate, and drives the moving member 46 to move by means of the rotation of the connecting rod 45. The moving member 46 then drives the blade 30 to rotate and open the ventilation hole through the connection with the blade 30.
[0061] The moving member 46 is provided with a first moving groove 461 and a second moving groove 462. A matching column 454 protrudes from the lateral side of the connecting rod 45 close to the moving member 46, and the matching column 454 extends into the first moving groove 461. One end of the blade 30 extends into the second moving groove 462. In this way, the first moving groove 461 provides a space for the matching column 454 to move, enabling the rotation of the connecting rod 45 to be converted into the horizontal movement of the moving member 46, and the lateral movement of the moving member 46 can drive the blade 30 to rotate through the second moving groove 462, thus realizing the actuation between the connecting rod 45 and the blade 30.
[0062] The first moving groove 461 and the second moving grooves 462 both extend along the vertical direction, and there are multiple second moving grooves 462 which are evenly spaced along the vertical direction; there are multiple vanes 30, and one end of each vane 30 close to the driving assembly 40 respectively extends into one of the second moving grooves 462. In this way, the multiple second moving grooves 462 can drive the multiple vanes 30 simultaneously, that is, the ventilation opening 111 is blocked or opened through the opening and closing of the multiple vanes 30, and its opening and closing efficiency is high, and the opening force required for each vane 30 is also small. The multiple second moving grooves 462 are evenly spaced, so the vanes 30 can be arranged more neatly in response to the arrangement of the second moving grooves 462.
[0063] On one side of the fixed seat 114 close to the moving member 46, a guiding rib 1141 is formed, and the guiding rib 1141 abuts against the moving member 46. In this way, by means of the abutment between the guiding rib 1141 and the moving member 46, the movement of the moving member 46 in the horizontal direction can be made more stable.
[0064] A rotating hole is formed in the fixed seat 114. On one side of the connecting rod 45 close to the fixed seat 114, a rotating column 451 protrudes, and the rotating column 451 extends into the rotating hole. In this way, since the fixed seat 114 is connected to the inner wall of the press chamber 11 and its position is relatively fixed, after the connecting rod 45 is connected to it through the rotating column 451, the connecting rod 45 also rotates stably around the axis of the rotating column 451, so that while the connecting rod 45 drives the moving member 46 through the mating column 454, its own position will not be affected.
[0065] The driving assembly 40 further includes a second elastic member 47. One end of the second elastic member 47 is connected to the connecting rod 45, and the other end abuts against the inner bottom wall of the press chamber 11. In this way, when the refrigerator door 20 is opened, that is, away from the box body 10, the refrigerator door 20 releases the abutment against the connecting rod 45, and the connecting rod 45 returns to its original position through the second elastic member 47. At the same time, through the abutting effect between the mating column 454 and the first moving groove 461, the moving member 46 is pulled to move horizontally, driving the vane 30 to close.
[0066] Further, the connecting rod 45 includes a first section 452 and a second section 453, the first section 452 and the second section 453 are arranged at an angle, and the first section 452 extends out of the press chamber 11, and one end of the second section 453 away from the first section 452 abuts against the second elastic member 47. In this way, the first section 452 and the second section 453 play their respective roles independently without affecting each other. After the second section 453 is arranged at an angle with the first section 452, the second section 453 is abutted by the refrigerator door 20 and moves downward, and due to the angle setting between the first section 452 and the second section 453, the first section 452 can convert the downward movement trend of the second section 453 into a movement at other angles. Thus, the lateral driving of the moving member 46 is realized.
[0067] Specifically, in this embodiment, the first section 452 and the second section 453 tend to be vertically arranged. Therefore, when the first section 452 moves downward, the second section 453 moves horizontally. And the two are connected by an arc structure, that is, one end of the first section 452 close to the second section 453 is bent into an arc, and one end of the second section 453 close to the first section 452 is also bent into an arc. The arcs at the ends of the first section 452 and the second section 453 that are close to each other are the same, so as to reduce the interference with other structures during the rotation of the connecting rod 45, and its rotation path is also more linearly consistent.
[0068] Compared with the prior art, in the second embodiment, by arranging the connecting rod 45 in the press chamber 11, the connecting rod 45 extends out of the upper wall surface of the press chamber 11, so that the connecting rod 45 extends into the path of the refrigerator door 20 opening or closing. Therefore, when the refrigerator door 20 is closed, it can abut against and press the connecting rod 45, causing the connecting rod 45 to avoid the refrigerator door 20 and rotate downward, and driving the moving member 46 to drive the blade 30 to rotate, realizing the opening of the ventilation opening 111; when the refrigerator door 20 is opened, the elastic potential energy of the second elastic member 47 is released to drive the connecting rod 45 to return to its original position, and at the same time, the moving member 46 drives the blade 30 to rotate to close the ventilation opening 111.
[0069] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0070] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
