Description

Technical Field

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

[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend. Most refrigerators on the market currently use single-axis or double-axis hinges to achieve the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator and ensure that the refrigerator door does not exceed the side of the refrigerator during the process of opening and closing the door, thereby avoiding interference with the side cabinet wood boards.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the box door. Although this design can reduce the integration degree of the electrical appliance and the home, it also increases the thickness of the entire door body assembly. This results in that after the electrical appliance is pushed into the cavity, relying only on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thus causing the door body assembly of the electrical appliance to be unable to be normally opened or closed. Summary of the Utility Model

[0004] The utility model aims to at least solve one of the technical problems existing in the related art. For this purpose, the utility model provides a door body assembly to solve the problem that the door body assembly with a door panel may interfere with the side of the installation space body during the process of opening and closing the door, resulting in the door body assembly of the electrical appliance being unable to be normally opened or closed.

[0005] The utility model also provides an ice-making device.

[0006] According to the door body assembly of the first aspect embodiment of the utility model, it includes:

[0007] A box door, rotatably connected to the electrical appliance body, suitable for opening or closing the storage space of the electrical appliance body;

[0008] A door panel, slidably arranged outside the box door;

[0010] According to the door body assembly of the first embodiment of the utility model, when the user needs to open the door body assembly, the door body assembly is moved to rotate outward relative to the electrical appliance body. During the rotation of the door body assembly, the pressure on the side of the cylinder body away from the transmission member is controlled to rise. Since the total volume of the cylinder body remains unchanged, the excess pressure on the side of the cylinder body away from the transmission member needs to be moved through the second end of the transmission member to be balanced by changing the volume of the space formed by the side of the cylinder body away from the transmission member and the transmission member as a whole. At this time, the second end of the transmission member drives the door panel to slide relative to the box door. When the equipment installed with the door body assembly is embedded, the door panel always avoids the walls on both sides of the width direction of the door body assembly during the opening of the door body assembly. When the user closes the door body assembly, in the same way, the pressure on the side of the cylinder body close to the transmission member is controlled to increase, so that the overall volume of the cylinder body close to the transmission member and the transmission member increases, so that the second end of the transmission member moves toward the cylinder body to drive the door panel to reset.

[0011] According to the door body assembly of the embodiment of the utility model, a cylinder driving transmission member is provided to drive the door panel to slide relative to the box door, so that the door panel assembly can be staggered against the side walls during opening and closing, thereby avoiding interference between the door panel and the outside when the box door rotates, and meeting the user's usage requirements in different scenarios; and when the door panel assembly is in the closed state, the box door and the electrical body are hidden on the side of the door panel away from the user, effectively improving the aesthetics.

[0041] The following is combined with Figures 1 to 3 Describe the door body assembly and refrigeration equipment of the present application. The door body assembly in the present application can be applied to household appliances, such as refrigerators. However, it should be understood that the door body assembly of the present application can also be applied to dishwashers, washing machines or any other suitable equipment. The refrigeration equipment in the present application is, for example, applied as a refrigerator. However, it should be understood that the refrigeration equipment of the present application can also be applied as a freezer or any other suitable equipment.

[0042] The door body assembly according to the first aspect embodiment of the present utility model includes a cabinet door 10, a door panel 30 and a transmission mechanism 40; the cabinet door 10 is rotatably connected to the electrical appliance main body 20 and is adapted to open or close the storage space of the electrical appliance main body 20; the door panel 30 is slidably disposed on the outer side of the cabinet door 10; the transmission mechanism 40 includes a cylinder block 41 and a transmission member 42. The first end of the transmission member 42 is hermetically connected to the cylinder block 41, and the second end can move relative to the cylinder block 41. The transmission mechanism 40 is disposed on one of the cabinet door 10 or the door panel 30, and the second end of the transmission member 42 is connected to the other. The transmission mechanism 40 is adapted to control the movement of the second end of the transmission member 42 through the pressure change of the cylinder block 41 to realize the relative sliding of the door panel 30 and the cabinet door 10.

[0043] According to the door body assembly of the first embodiment of the utility model, when the user has the need to open the door body assembly, the door body assembly is moved to rotate outward relative to the electrical main body 20. During the rotation of the door body assembly, the pressure on the side of the cylinder body 41 away from the transmission member 42 is controlled to rise. Since the total volume of the cylinder body 41 remains unchanged, the excess pressure on the side of the cylinder body 41 away from the transmission member 42 needs to be moved through the second end of the transmission member 42, so as to be balanced by changing the volume of the space formed by the side of the cylinder body 41 away from the transmission member 42 and the transmission member 42 as a whole. At this time, the second end of the transmission member 42 drives the door panel 30 to slide relative to the box door 10. When the equipment installed on the door body assembly is embedded, the door panel 30 always avoids the walls on both sides of the width direction of the door body assembly during the opening of the door body assembly. Similarly, when the user closes the door body assembly, the pressure on the side of the cylinder body 41 close to the transmission member 42 is controlled to increase, so that the overall volume of the cylinder body 41 close to the transmission member 42 and the transmission member 42 increases, so that the second end of the transmission member 42 moves toward the cylinder body 41 to drive the door panel 30 to reset.

[0044] According to the door body assembly of the embodiment of the utility model, a cylinder body 41 is provided to drive the transmission member 42 to drive the door panel 30 to slide relative to the cabinet door 10, so that the door panel 30 assembly can be staggered from the side wall during opening and closing, thereby avoiding interference between the door panel 30 and the outside when the cabinet door 10 rotates, and meeting the user's usage requirements in different scenarios; and when the door panel 30 assembly is in the closed state, the cabinet door 10 and the electrical appliance body 20 are hidden on the side of the door panel 30 away from the user, effectively improving the aesthetics.

[0045] In this embodiment, the transmission mechanism 40 is arranged on the box door 10, and the second end of the transmission member 42 is connected to the door panel 30, which is conducive to the connection between the cylinder body 41 of the transmission mechanism 40 and the power supply circuit or control circuit in the box door 10; of course, the transmission mechanism 40 can also be arranged on the door panel 30, and the second end of the transmission member 42 is connected to the box door 10 to realize the relative sliding of the driving box door 10 and the door panel 30.

[0046] In this embodiment, the cylinder body 41 may be a hydraulic cylinder, and liquid may be filled into the cylinder body 41 to change the internal pressure of the cylinder body 41 and the transmission member 42 as a whole; of course, other types of cylinder bodies 41 may also be used based on different media (such as air).

[0047] In this embodiment, the pressure of the cylinder 41 can be controlled by using a control button, such as a user pressing a control button to control the pressure of the cylinder 41 to increase or decrease; or a sensor 70 can be set to automatically detect whether the door assembly moves relative to the appliance body to automatically control the pressure of the cylinder 41.

[0048] According to one embodiment of the utility model, combined Figure 1 and Figure 2As shown, the transmission member 42 includes a translation rod 421, and the cylinder block 41 is provided with a piston rod 422; the cylinder block 41 includes a door-opening cylinder 411, and one end of the piston rod 422 of the door-opening cylinder 411, which is far away from the door-opening cylinder 411, abuts against the first side of the translation rod 421.

[0049] In this embodiment, when the door body assembly covers the electrical appliance body, the piston rod 422 is at least partially buried inside the cylinder block 41, so that the translation rod 421 connected to the piston rod 422 is close to the cylinder block 41, and the door panel 30 shields the box door 10. When the user opens the door panel 30 assembly, the pressure on the side of the cylinder block 41 away from the translation rod 421 increases. Through the movement of the piston rod 422, the overall volume enclosed by the piston rod 422 and the side of the cylinder block 41 away from the translation rod 421 increases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the piston rod 422 moves away from the cylinder block 41, thereby driving the door panel 30 to slide outward relative to the box door 10.

[0050] By arranging the translation rod 421 and the piston rod 422, the piston rod 422 always moves along the inner wall of the cylinder block 41, and the movement is stable and reliable. Moreover, when the piston rod 422 contracts inside the cylinder block 41, the overall volume of the transmission mechanism 40 can be effectively reduced to reduce the volume of the door body assembly.

[0051] In other embodiments, the piston rod 422 can also be replaced with a hollow multi-section push rod. Under the action of the pressure inside the cylinder block 41, the multi-layer sleeves of the multi-section hollow push rod change from being nested to being misaligned, so as to increase the overall volume of the multi-section hollow push rod and the cylinder block 41, thereby balancing the pressure inside the cylinder block 41. At this time, one end of the multi-section hollow push rod is connected to the cylinder block 41 and does not move, and the other end pushes the translation rod 421.

[0052] In one embodiment, in combination with Figure 1 and Figure 2 As shown, the transmission mechanism 40 further includes a reset member 43. The first end of the reset member 43 is fixed relative to the door-opening cylinder 411, and the second end is connected to the translation rod 421, and is adapted to drive the translation rod 421 to reset in the contraction direction of the piston rod 422.

[0053] In this embodiment, the reset member 43 can always provide a certain pushing force to the translation rod 421 (that is, the force from left to right in Figure 1). If it is in the form of an elastic member, when the pushing force provided by the right door-opening cylinder 411 and the piston rod 422 cannot overcome the pushing force of the reset member 43, under the action of the reset member 43, the translation rod 421 will move towards the door-opening cylinder 411, and the corresponding door panel 30 will reset relative to the box door 10.

[0054] Of course, the reset member 43 can also be a way to provide a thrust only when the door body assembly has a closing tendency relative to the electrical main body 20. For example, a pump body or a cylinder body 41 is provided on the side of the translation rod 421 away from the door cylinder 411 to push against the translation rod 421.

[0055] According to an embodiment of the present invention, the reset member 43 includes a reset cylinder 412. The opening cylinder 411 and the reset cylinder 412 are arranged on both sides of the translation rod 421. One end of the piston rod 422 of the reset cylinder 412 away from the reset cylinder 412 abuts against the second side of the translation rod 421, and the second side is arranged opposite to the first side.

[0056] In this embodiment, taking the example of the user closing the door panel 30 assembly, the internal pressure on the side of the reset cylinder 412 away from the translation rod 421 is controlled to rise. The piston rod 422 of the reset cylinder 412 moves towards the translation rod 421, so that the overall volume enclosed by the side of the reset cylinder 412 away from the translation rod 421 and the piston rod 422 increases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the piston rod 422 moves towards the opening cylinder 411. And the internal pressure on the side of the opening cylinder 411 away from the translation rod 421 decreases. The piston rod 422 of the opening cylinder 411 moves away from the translation rod 421, so that the overall volume enclosed by the side of the opening cylinder 411 away from the translation rod 421 and the piston rod 422 decreases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the piston rod 422 of the opening cylinder 411 moves towards the opening cylinder 411. Under the combined action of the reset cylinder 412 and the opening cylinder 411, the translation rod 421 drives the door panel 30 to slide inwards relative to the box door 10. When the user opens the door body assembly, it is the same in principle, just in the reverse direction. By setting the reset cylinder 412 and the opening cylinder 411, compared with using only the reset cylinder 412 or the opening cylinder 411, the moving efficiency of the translation rod 421 is higher, effectively improving the moving efficiency of the door panel 30.

[0057] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the transmission mechanism 40 further includes a reversing valve 45, which is connected to an external medium source. The reversing valve 45 is arranged between the inlet of the opening cylinder 411 and the inlet of the reset cylinder 412, and is adapted to introduce the medium of the external medium source into one of the opening cylinder 411 or the reset cylinder 412, and to return the medium in the other to the external medium source. The reversing valve 45 controls one of the opening cylinder 411 or the reset cylinder 412 to introduce the medium of the external medium source to increase the pressure inside the cylinder body 41 to move the piston rod 422.

[0058] In one embodiment, the outlets of the door opening cylinder 411 and the reset cylinder 412 are communicated with an external medium source. Taking the example of the user closing the door panel 30 assembly, at this time, the control reversing valve 45 switches its state, and the external medium source flows through the reversing valve 45 to the side of the door opening cylinder 411 away from the translational rod 421, so that the piston rod 422 of the door opening cylinder 411 moves towards the translational rod 421, and then squeezes the medium on the side of the door opening cylinder 411 close to the translational rod 421 to flow back from the outlet of the door opening cylinder 411 to the external medium source; while the piston rod 422 of the reset cylinder 412 is pushed by the translational rod 421 to move away from the translational rod 421, and the medium of the external medium source is replenished through the outlet of the reset cylinder 412 to the space on the side of the reset cylinder 412 close to the translational rod 421, the space on the side of the reset cylinder 412 away from the translational rod 421 decreases, and the medium flows back to the external medium source through the reversing valve 45. When the user opens the door body assembly, it is the same in principle, just in the reverse direction.

[0059] In one embodiment, the outlet of the door opening cylinder 411 is communicated with the outlet of the reset cylinder 412. Taking the example of the user closing the door panel 30 assembly, at this time, the control reversing valve 45 switches its state, and the external medium source flows through the reversing valve 45 to the side of the door opening cylinder 411 away from the translational rod 421, so that the piston rod 422 of the door opening cylinder 411 moves towards the translational rod 421, and then squeezes the medium on the side of the door opening cylinder 411 close to the translational rod 421 to flow from the outlet of the door opening cylinder 411 to the outlet of the reset cylinder 412 and enter the side of the reset cylinder 412 close to the translational rod 421. Part of the piston rod 422 in the reset cylinder 412 is squeezed by the medium to move away from the translational rod 421, so that the space on the side of the reset cylinder 412 away from the translational rod 421 decreases, and the medium flows back to the external medium source through the reversing valve 45. When the user opens the door body assembly, it is the same in principle, just in the reverse direction.

[0060] In this embodiment, when the door opening cylinder 411 or the reset cylinder 412 is a hydraulic cylinder, the external medium source can be oil; when other types of cylinders 41 are used, the type of the external medium source can be correspondingly replaced.

[0061] In this embodiment, the reversing valve 45 can be automatically switched by an electromagnetic valve based on a signal, and the signal can be obtained by detecting through a sensor 70; of course, a manual valve can also be used and the user can manually control the state of the reversing valve 45.

[0062] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 as shown, along the moving direction of the translational rod 421, the piston rod 422 of the door opening cylinder 411 and the piston rod 422 of the reset cylinder 412 are arranged in a staggered manner. To reduce the length of the transmission mechanism 40 in the moving direction of the translational rod 421, and correspondingly increase the thickness perpendicular to the moving direction, so as to adapt to the door body assembly with a smaller size in the moving direction of the translational rod 421.

[0063] According to an embodiment of the present utility model, the door body assembly further includes a sensor 70. The sensor 70 is adapted to detect the movement of the door body assembly relative to the electrical appliance main body 20. The sensor 70 is connected to the transmission mechanism 40 and controls the movement of the transmission mechanism 40 based on the movement state of the door body assembly relative to the electrical appliance main body 20.

[0064] In this embodiment, the movement detected by the sensor 70 can be transmitted to the cylinder block 41 of the transmission mechanism 40 in the form of a signal. For example, when the sensor 70 detects that the door body assembly is moving away from the electrical appliance main body 20, it can emit a positive signal, and when it detects that the door body assembly is approaching the electrical appliance main body 20, it can emit a negative signal. Here, the positive signal and the negative signal are not relative relationships, and only uniqueness is required to control the state of the cylinder block 41. For example, the positive signal can be a high-level signal, and the negative signal can be a low-level signal.

[0065] In a specific embodiment, when the user closes the door body assembly, the sensor 70 detects the movement of the door body assembly relative to the electrical appliance main body 20 and emits a negative signal. The transmission mechanism 40 controls the internal pressure of the cylinder block 41 based on the negative signal. For example, it controls the internal pressure on the side of the reset cylinder 412 away from the translation rod 421 to increase. The piston rod 422 of the reset cylinder 412 moves towards the translation rod 421 direction, so that the overall volume enclosed by the side of the reset cylinder 412 away from the translation rod 421 and the piston rod 422 increases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the piston rod 422 moves towards the opening cylinder 411 direction; while the internal pressure on the side of the opening cylinder 411 away from the translation rod 421 decreases. The piston rod 422 of the opening cylinder 411 moves in the direction away from the translation rod 421, so that the overall volume enclosed by the side of the opening cylinder 411 away from the translation rod 421 and the piston rod 422 decreases to balance the pressure. Correspondingly, the translation rod 421 connected to the second end of the piston rod 422 of the opening cylinder 411 moves towards the opening cylinder 411 direction. Under the combined action of the reset cylinder 412 and the opening cylinder 411, the translation rod 421 drives the door panel 30 to slide inwards relative to the box door 10. When the user opens the door body assembly, the principle is the same. The sensor 70 generates a positive signal, and the transmission mechanism 40 controls the internal pressure of the cylinder block 41 based on the positive signal.

[0066] In this embodiment, the movement of the door body assembly relative to the electrical appliance main body 20 is automatically detected by the sensor 70 without user control, effectively improving the timeliness of the movement of the door panel 30 relative to the box door 10 and ensuring the safety of the movement of the door panel 30. And by changing the parameters of the transmission mechanism 40 (such as the unit input-output of the cylinder block 41, the length of the piston rod 422, etc.), the movement speed of the door panel 30 relative to the box door 10 can be changed, effectively adapting to the requirements in different situations.

[0067] In this embodiment, the door body assembly may further include a main control board and a pre-buried wire (not shown in the figure). The main control board is connected to the sensor 70 and the transmission mechanism 40 through the pre-buried wire. The main control board may control the operation of the transmission mechanism 40 based on the positive or negative signal fed back by the sensor 70.

[0068] In this embodiment, the sensor 70 may be a distance sensor, which is fixed to the cabinet door 10 or the electrical appliance main body 20. During the opening and closing process of the door body assembly, the distance between the cabinet door 10 and the electrical appliance main body 20 changes to generate a signal.

[0069] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 as shown, the translational rod 421 is provided with a slider 4221, and the door panel 30 or the cabinet door 10 is provided with a sliding groove 11 corresponding to the slider 4221.

[0070] In this embodiment, the sliding groove 11 is provided on the cabinet door 10. During the movement of the translational rod 421, the slider 4221 always moves along the sliding groove 11, effectively improving the movement stability of the translational rod 421. Of course, when the transmission mechanism 40 is provided on the door panel 30, the sliding groove 11 is opened on the door panel 30.

[0071] In another embodiment, the sliding groove 11 may also be provided on the translational rod 421, and the door panel 30 or the cabinet door 10 is provided with a slider 4221 corresponding to the sliding groove 11, and it is only necessary to ensure that the slider 4221 and the sliding groove 11 cooperate to achieve the movement stability of the translational rod 421.

[0072] According to an embodiment of the present invention, in combination with Figure 3 as shown, a guiding portion 60 extending along the relative movement direction of the door panel 30 and the cabinet door 10 is provided between the door panel 30 and the cabinet door 10, and the guiding portion 60 is adapted to support the door panel 30.

[0073] The guiding portion 60 may include a guiding base and a guiding slider. The guiding base is provided on the cabinet door 10, a guide rail is formed on the guiding base, and the guiding slider is slidably provided on the guide rail, and the guiding slider is connected to the door panel 30.

[0074] Among them, the guiding slider is connected to the door panel 30, and this connection method can be selected according to actual needs, such as by screws, welding, snap-fasteners, etc. Through this connection method, when the door panel 30 and the cabinet door 10 slide relative to each other, the door panel 30 can push the guiding slider to slide on the guide rail, which can greatly increase the stability during the relative sliding process of the door panel 30 and the cabinet door 10.

[0075] In addition, by designing the guide rail, such as setting a limit structure at the end of the guide rail, the moving distance of the door panel 30 can also be adjusted according to actual needs to meet the needs of different users.

[0076] In this embodiment, guiding parts 60 are provided at three of the four corners of the door body assembly, and a transmission mechanism 40 is provided at the remaining one corner; of course, the number of the guiding parts 60 can be adjusted accordingly based on requirements such as the weight of the door panel 30 and the sliding stability between the door panel 30 and the box door 10.

[0077] According to an embodiment of the present invention, the transmission mechanism 40 is arranged at the top of the door panel 30 or the box door 10. This is convenient for the staff to repair and replace the components of the transmission mechanism 40, and improves the maintenance and installation efficiency.

[0078] The refrigeration device according to the second aspect embodiment of the present invention includes the door body assembly as described in the above embodiment.

[0079] The beneficial effects of the refrigeration device according to the embodiment of the present application are the same as those of the door body assembly in the first aspect embodiment of the present application, and will not be elaborated here.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should all be covered by the scope of the claims of the present invention.
