Technical Field

[0001] The present invention relates to the field of refrigeration devices, and particularly to a refrigeration device. Background Art

[0002] Due to the characteristic of maintaining a constant low temperature, refrigerators are widely used in both household and commercial fields. In addition to the basic refrigeration function, some refrigerators have display and control functions. In recent years, businesses have increasingly emphasized the display and control usage experience of refrigerator users.

[0003] Due to factors such as cost and aesthetics, the traditional display and control interface of refrigerators can no longer meet modern usage requirements. With the progress of technology, projection display solutions have emerged in recent years. However, existing projection display solutions have various limitations or defects in terms of applicability, stability, safety, and aesthetics that conflict with and contradict the actual usage scenarios, such as not conforming to usage habits, human-machine mismatch, and being divorced from reality. These limitations or defects can cause problems such as inability to use, wasted space, wasted cooling capacity, increased energy consumption, cumbersome operation, inconvenient use, easy damage, strange visual effects, and being unreasonable. In addition, when existing refrigerators implement image projection, the size of the display area is fixed, and the single-size display method cannot meet the needs of different users. Summary of the Invention

[0004] The purpose of the present invention is to provide a refrigeration device.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions: A refrigeration device includes a box body having an opening and a door body for opening or closing the opening. The door body has an outer surface on a side away from the opening; the outer surface has a first groove and a projection area located outside the first groove; the refrigeration device further includes a projection mechanism, and the projection mechanism includes:

[0006] A rotation assembly, the rotation assembly includes a rotating member rotatably connected in the first groove and a reflector rotatably connected to the free end of the rotating member. The rotation assembly has a first state in which both the rotating member and the reflector are parallel to the bottom of the first groove and a second state in which the free end of the rotating member rotates away from the first groove to a preset position. When the rotation assembly is in the second state, the angle between the rotating member and the bottom of the first groove is less than 90°, and at the same time, the angle between the rotating member and the reflector is less than 180°, and the reflecting surface of the reflector faces the projection area;

[0007] A projection member for projecting a display interface onto the reflector. When the rotation assembly is in the second state, the display interface projected by the projection member is reflected by the reflecting surface to the projection area.

[0011] As a further improvement of the present invention, when the rotating assembly is in the first state, the rotating member and the reflector are coplanar or the reflector is folded to the side of the rotating member facing the bottom of the groove.

[0012] As a further improvement of the present invention, when the rotating assembly is in the first state, the rotating assembly is received in the first groove or the rotating assembly is located outside the first groove.

[0013] As a further improvement of the present invention, the projection mechanism further includes a power supply switch provided in the first groove and used to supply power to the projection member, and the power supply switch is located on the moving path of the rotating end of the rotating member; when the rotating assembly is in the second state, the rotating end acts on the power supply switch, and the projection member is started.

[0014] As a further improvement of the present invention, a second groove is recessed at a position corresponding to the rotating end on the bottom of the first groove. When the rotating assembly switches from the first state to the second state, the rotating end enters the second groove; the second groove has an inclined surface adapted to the rotating member in the second state, and the power supply switch is provided on the inclined surface; when the rotating assembly is in the second state, the rotating end of the rotating member abuts against the inclined surface.

[0015] As a further improvement of the present invention, the refrigeration device further includes a locking assembly for making the rotating assembly in the first state and an elastic member for driving the rotating member to rotate when the locking assembly is in the unlocked state; the locking assembly is a press self-locking buckle assembly connected between the first groove and the rotating member.

[0016] As a further improvement of the present invention, the rotating assembly further includes a positioning mechanism provided between the reflector and the rotating member. When the rotating assembly is in the second state, the positioning mechanism is used to limit the relative rotation of the reflector with respect to the rotating member.

[0017] The beneficial effects of the present invention are as follows: In the refrigeration device of the present invention, on the one hand, the projection mechanism and the projection area are both arranged on the outer surface of the door body. The display interface is the front panel of the door body itself, without the need to additionally provide other dedicated display components. Moreover, the position of the projection area can be selected according to the user's habit, which conforms to human-computer interaction, is reasonably and naturally matched, and is convenient for the user to operate. In addition, there is no need to open the door body to view the display interface, so that any disturbance to the existing refrigeration balance inside the refrigerator is not caused, and cold loss and energy waste will not occur. And when the door body rotates, the projection mechanism and the display interface located in the projection area rotate together with the door body, which will not cause relative movement between the projection mechanism and the projection area, thereby interfering with the projection, ensuring the normal use of the refrigerator while being convenient for the user to operate or view the display interface displayed in the projection area. On the other hand, a reflector is added to project the display interface of the projection member to the projection area, and the reflector is arranged to be rotatably connected to the rotating member, which can further reduce the rotation opening angle of the rotating member and will not affect the overall appearance effect of the door body due to the excessive protrusion of the rotating assembly.

[0023] The present invention will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present invention.

[0024] For the words expressing directions in the present invention, with Figure 1 the projection assembly 11 in the second state in

[0025] In the present invention, unless otherwise clearly specified and defined, terms such as "connected" and "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, a movable connection, or an integral body; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components or the interaction relationship between two components such as abutment. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. It should be noted that when there are qualifiers before "connected" and "coupled", they have the meanings defined by the corresponding qualifiers, only excluding the obvious cases that need to be excluded, and not excluding other possible cases. For example, "detachable connection" refers to a detachable connection, excluding being an integral body, but a movable connection and the like are not excluded.

[0026] Please refer to Figures 1 to 3 As shown, the present invention discloses a refrigeration device 10, which includes a box body 1 having an opening and a door body 2 for opening or closing the opening. Hereinafter, taking the refrigeration device 10 as a vertical refrigerator as an example for specific elaboration. At this time, the door body 2 is located on the front side of the box body 1. Of course, this is not limited thereto.

[0027] Specifically, the door body 2 has an outer surface on a side away from the opening. The outer surface is recessed with a first groove 21 and a projection area 22 located outside the first groove 21. The refrigeration device 10 further includes a projection mechanism. The projection mechanism includes a rotating assembly 3 installed in the first groove 21 and a projection member 4 for projecting a display interface.

[0028] It can be known that when the refrigeration device 10 is a vertical refrigerator, the above-mentioned outer surface of the door body 2 refers to the front surface of the door body 2.

[0029] The rotating assembly 3 includes a rotating member 31 rotatably connected within the first groove 21, and a reflecting plate 32 rotatably connected to the free end of the rotating member 31. The rotating assembly 3 has a first state in which both the rotating member 31 and the reflecting plate 32 are parallel to the bottom of the first groove 21, and a second state in which the free end of the rotating member 31 rotates away from the first groove 21 to a preset position. When the rotating assembly 3 is in the first state, the projection mechanism as a whole is in a storage state. At this time, the projection member 4 is in a closed state, making the appearance of the door body 2 beautiful and tidy, and there will be no collision during the transportation or use of the refrigerator. When the rotating assembly 3 is in the second state, the included angle between the rotating member 31 and the bottom of the first groove 21 is less than 90°, and at the same time, the included angle between the rotating member 31 and the reflecting plate 32 is less than 180°. The reflecting surface of the reflecting plate 32 faces the projection area 22. Thus, the display interface projected from the projection member 4 can be reflected to the projection area 22 through the reflecting surface, facilitating user operation and use.

[0030] In the present invention, on the one hand, both the projection mechanism and the projection area 22 are provided on the outer surface of the door body 2. The display interface is the front panel of the door body 2 itself, without the need to additionally provide other dedicated display components. Moreover, the position of the projection area 22 can be selected according to the user's habit, which conforms to human-computer interaction, is reasonably and naturally matched, and is convenient for the user to control. At the same time, there is no need to open the door body 2 to view the display interface, so there will be no disturbance to the existing refrigeration balance inside the refrigerator, and there will be no cold loss and energy waste. And when the door body 2 rotates, the projection mechanism and the display interface located in the projection area 22 rotate together with the door body 2, and there will be no relative movement between the projection mechanism and the projection area 22, thus interfering with the projection. While ensuring the normal use of the refrigerator, it is convenient for the user to control or view the display interface displayed in the projection area 22. On the other hand, a reflecting plate 32 for projecting the display interface of the projection member 4 to the projection area 22 is added, and the reflecting plate 32 is arranged to be rotatably connected to the rotating member 31, which can further reduce the rotation opening angle of the rotating member 31 and will not affect the overall appearance of the door body 2 due to the excessive protrusion of the rotating assembly 3.

[0031] In a specific embodiment where the refrigeration device 10 is a vertical refrigerator, as Figure 1 shown, the upper end of the rotating member 31 is the rotating end of the rotating member 31, the lower end of the rotating member 31 is the free end of the rotating member 31, the reflecting plate 32 is rotatably connected to the free end, and the projection area 22 is located below the first groove 21. Of course, it is not limited thereto.

[0032] Further, when the rotating assembly 3 is in the second state, the sum of the angle between the rotating member 31 and the bottom of the groove and the angle between the rotating member 31 and the reflector 32 is not greater than 180°, and the angle between the rotating member 31 and the reflector 32 is greater than 90°, so that the display interface projected by the projector 4 can be reflected by the reflector 32 to the projection area 22 provided at a preset position.

[0033] In a specific embodiment, when the rotating assembly 3 is in the second state, the reflector 32 is parallel to the projection area 22, that is, the sum of the angle between the rotating member 31 and the bottom of the groove and the angle between the rotating member 31 and the reflector 32 is 180°. Of course, this is not the limit.

[0034] Please refer Figures 2 to 3 as shown, including the projection mechanism in the first embodiment of the present invention, the projector 4 is fixed on one side of the rotating member 31 facing the bottom of the first groove 21.

[0035] Further, the projection mechanism further includes a locking assembly 5 for making the rotating assembly 3 in the first state, and an elastic member (not shown) for driving the rotating member 31 to rotate when the locking assembly 5 is in the unlocked state.

[0036] In a specific embodiment, the locking assembly 5 is a press self-locking buckle assembly connected between the first groove 21 and the rotating member 31. The press self-locking buckle assembly includes a latch provided on one of the bottom of the first groove 21 and the rotating member 31, at least two claws provided on the other, and a driving mechanism for driving the at least two claws to open or close. The driving mechanism is configured to drive the at least two claws to switch between opening and closing under the action of a pressing force. When the at least two claws are in the open state, the locking assembly 5 is in the unlocked state. At this time, the rotating assembly 3 is in the second state. When the at least two claws are in the closed state, the locking assembly 5 is in the locked state. At this time, the rotating assembly 3 is in the first state.

[0037] Specifically, when the locking component 5 is in the locked state, press the rotating member 31 inward (towards the direction of the bottom of the first groove 21). The free end of the rotating member 31 moves towards the inside of the first groove 212. The clamping block and the clamping claw move relative to each other. The clamping block transmits the pressing force to the driving mechanism. The driving mechanism switches at least two clamping claws from the closed state to the open state. The locking component 5 switches from the locked state to the unlocked state. At this time, remove the pressing force applied to the rotating member 31. Driven by the elastic member, the rotating member 31 rotates away from the first groove 21 to switch the rotating assembly 3 to the second state. When the locking component 5 is in the unlocked state, by pressing the rotating member 31 inward until the clamping block is located between at least two clamping claws and continuing to press inward. After the clamping block transmits the pressing force to the driving mechanism, the driving mechanism switches at least two clamping claws from the open state to the closed state, and the locking component 5 is in the locked state.

[0038] The driving mechanism in the pressing self-locking buckle assembly and the connection structure between the driving mechanism and the clamping claw can adopt the driving mechanism in the existing pressing self-locking buckle assembly and the connection structure between the driving mechanism and the clamping claw. For example, details are not described herein again.

[0039] In a specific embodiment, the rotating member 31 and the first groove 21 are rotationally connected through a rotating shaft. The elastic member is a torsion spring sleeved on the rotating shaft. One end of the torsion spring abuts against the first groove 21, and the other end abuts against the rotating member 31. When the rotating assembly 3 is in the first state, the torsion spring is in an elastically deformed state. Under the action of the elastic restoring force of the torsion spring, the rotating member 31 has a tendency to rotate outward. Thus, after the locking component 5 switches from the locked state to the unlocked state, the torsion spring drives the rotating member 31 to rotate outward, causing the rotating assembly 3 to switch to the second state.

[0040] Furthermore, the rotating assembly 3 further includes a positioning mechanism disposed between the reflector 32 and the rotating member 31. When the rotating assembly 3 is in the second state, the positioning mechanism is used to limit the relative rotation of the reflector 32 with respect to the rotating member 31.

[0041] In a specific embodiment, the reflector 32 and the rotating member 31 are rotatably connected through a rotating shaft. The positioning mechanism is a torsion spring sleeved on the rotating shaft. One end of the torsion spring acts on the reflector 32, and the other end acts on the rotating member 31. When the rotating assembly 3 is in the first state, the reflector 32 abuts against the outer surface of the door body 2, and the torsion spring is in an elastically deformed state. Under the action of the elastic restoring force of the torsion spring, a rotational tendency for the reflector 32 to rotate relative to the rotating member 31 is provided. Thus, when the rotating member 31 rotates away from the first groove 21, the reflector 32 is driven away from the outer surface of the door body 2, and the torsion spring drives the reflector 32 to rotate relative to the rotating member 31. When the torsion spring is in a free state, the rotating assembly 3 switches to the second state. At this time, the torsion spring provides a supporting force to the reflector 32 to prevent the reflector 32 from rotating relative to the rotating member 31.

[0042] Further, the projection mechanism further includes a power supply switch 6 disposed in the first groove 21. The power supply switch 6 is used to supply power to the projection member 4 to start the projection member 4.

[0043] Further, the power supply switch 6 is located on the moving path of the rotating end. When the rotating assembly 3 is in the second state, the rotating end acts on the power supply switch 6, and then the projection member 4 is started. The projection member 4 projects an image onto the reflector 32. It can be known that in response to the unlocking of the rotating assembly 3, the elastic member drives the rotating assembly 3 to rotate outwards. While the rotating assembly 3 switches to the second state, the rotating end of the rotating member 31 acts on the power supply switch 6 to start the projection member 4. Without user operation, the projection member 4 can be automatically turned on, which is convenient and simple.

[0044] Further, a second groove 211 is recessed at a position corresponding to the rotating end at the bottom of the first groove 21. When the rotating member 31 rotates outwards, the rotating end enters the second groove 211. The second groove 211 can make way for the rotating end to prevent interference between the rotating end and the bottom of the first groove 21.

[0045] Specifically, the groove wall of the second groove 211 close to the projection area 22 is an inclined surface 2111, and the power supply switch 6 is disposed on the inclined surface 2111. When the rotating member 31 rotates outwards until the rotating end abuts against the inclined surface 2111, on the one hand, the rotating end acts on the power supply switch 6 to start the projection member 4; on the other hand, the inclined surface 2111 limits the rotating member 31 to prevent the rotating member 31 from further rotating outwards, so that the rotating assembly 3 remains in the second state, thereby ensuring that the projection member 4 can project at a preset position.

[0046] It can be understood that after the user finishes viewing and / or manipulating, the user presses the free end inward, the free end rotates inward, drives the rotating end to rotate outward and separate from the power supply switch 6. At this time, the projection member 4 is powered off and closed. That is, the inclined surface 2111 not only has the function of limiting the projection angle of the rotation assembly 3, but also has the function of finally determining the power-on to start projection and the first determination of power-off to close projection. Therefore, in addition to ensuring the above basic functions, it can also make the device work only when actually using the projection, thereby maximizing the shortening of the power consumption time and reducing the power consumption.

[0047] Further, as shown in Figure 2 In this embodiment, when the rotation assembly 3 is in the first state, the rotating member 31 and the reflector 32 are coplanar. Of course, this is not limited thereto. In other embodiments, when the rotation assembly 3 is in the first state, the reflector 32 can also be set to be folded to the side of the rotating member 31 facing the bottom of the groove.

[0048] Further, as shown in Figure 2 In this embodiment, when the rotation assembly 3 is in the first state, the rotation assembly 3 is received in the first groove 21, which can improve the appearance effect of the door body 2. At the same time, it can be understood that for the projection mechanism in the first embodiment of the present invention, when the rotation assembly 3 switches between the first state and the second state, since the reflector 32 will rotate relative to the rotating member 31, thus, the end of the reflector 32 will not interfere with the groove wall of the first groove 21. Of course, this is not limited thereto. As shown in Figure 4 In the second embodiment of the projection mechanism, when the rotation assembly 3 is in the first state, the rotation assembly 3 is located outside the first groove 21. At this time, the rotating member 31 and the reflector 32 are coplanar, and the rotation assembly 3 as a whole protrudes outside the first groove 21, and the reflector 32 abuts against the outer surface corresponding to the projection area 22, which can reduce the thickness of the first groove 21, thus not affecting the heat preservation effect of the door body 2.

[0049] Please refer to Figure 5 As shown, this is the third embodiment of the projection mechanism of the present invention. The difference between the projection mechanism in the third embodiment of the present invention and the projection mechanism in the first embodiment is that: the projection member 4a is a telescopic projection member 4. Thus, by controlling the telescopic of the projection member 4a, the size of the display interface projected onto the projection area 22 can be controlled, and thus, the size of the display interface can be adjusted according to user needs, improving the versatility of the projection mechanism.

[0050] Specifically, as shown in Figure 5As shown, in a specific embodiment, when the rotating assembly 3 is in the first state, the rotating assembly 3 is located outside the first groove 21. Of course, this is not a limitation. In other embodiments, when the rotating assembly 3 is in the first state, the rotating assembly 3 can also be arranged to be accommodated inside the first groove 21.

[0051] Except for the above differences, the projection mechanism in the third embodiment of the present invention is the same as the projection mechanism in the first embodiment, and thus will not be elaborated herein.

[0052] In the present invention, on the one hand, the projection mechanism and the projection area 22 are both arranged on the outer surface of the door body 2. The display interface is the front panel of the door body 2 itself, without the need to additionally provide other dedicated display components. Moreover, the position of the projection area 22 can be selected according to the user's habit, which conforms to human-computer interaction, is reasonably and naturally matched, and is convenient for the user to operate. In addition, there is no need to open the door body 2 to view the display interface, so that no disturbance is caused to the existing refrigeration balance inside the refrigerator, and no cold loss and energy waste will occur. And when the door body 2 rotates, the projection mechanism and the display interface located in the projection area 22 rotate together with the door body 2, which will not cause relative movement between the projection mechanism and the projection area 22, thereby interfering with the projection, ensuring the normal use of the refrigerator and being convenient for the user to operate or view the display interface displayed in the projection area 22. On the other hand, a reflector 32 for projecting the display interface of the projection member 4 onto the projection area 22 is added, and the reflector 32 is arranged to be rotatably connected to the rotating member 31, which can further reduce the rotation opening angle of the rotating member 31 and will not affect the overall appearance effect of the door body 2 due to the excessive protrusion of the rotating assembly 3.

[0053] It should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0054] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent embodiments or changes made without departing from the technical spirit of the present invention should be included in the protection scope of the present invention.
