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 protrude beyond the side of the refrigerator during the process of opening and closing the door, thus 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 cabinet door. Although this design can reduce the integration degree of the appliance and the home, it also increases the thickness of the entire door body assembly. This leads to the situation that after the 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, resulting in the inability to normally open or close the door body assembly of the appliance. Content of the Utility Model

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0042] The following will be combined with Figures 1 to 2 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 to freezers or any other suitable equipment.

[0043] Combined with Figure 1 And Figure 2 As shown in, the door body assembly according to the first aspect embodiment of the present utility model includes a cabinet door 10, a door panel 30, a driving assembly 40, a driven assembly 50, and a magnetic transmission mechanism 60; 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 driving assembly 40 and the driven assembly 50 are disposed on one of the cabinet door 10 or the door panel 30, and the driven assembly 50 is connected to the other; the magnetic transmission mechanism 60 includes a moving magnetic member 61 and a magnetic acceleration channel 62, and the driving assembly 40 is adapted to drive the moving magnetic member 61 to move along the magnetic acceleration channel 62 at an accelerated speed, so that the moving magnetic member 61 drives the driven assembly 50 to move.

[0044] For the door body assembly according to the embodiment of the present utility model, under the drive of the driving assembly 40, the moving magnetic member 61 starts to move from the starting end (the right side in the figure) of the magnetic acceleration channel 62 to the end (the left side in the figure). Under the magnetic field action of the magnetic acceleration channel 62, the moving magnetic member 61 is accelerated and contacts or impacts the driven assembly 50 at a higher speed, and then drives the door panel 30 to move relative to the cabinet door 10 through the movement of the driven assembly 50.

[0045] According to the door body assembly of the embodiment of the present utility model, by setting the driving assembly 40, the magnetic transmission mechanism 60 and the driven assembly 50 to drive the door panel 30 to slide relative to the box door 10, the door panel 30 assembly can be staggered from the side wall during the opening and closing processes, which can avoid the interference between the door panel 30 and the outside when the box door 10 rotates, and can meet the usage requirements of users in different scenarios; and when the door panel 30 assembly is in the closed state, the box door 10 and the electrical appliance main body 20 are hidden on the side of the door panel 30 away from the user, effectively improving the aesthetics; moreover, the magnetic acceleration channel 62 of the magnetic transmission mechanism 60 enables the driving assembly 40 to only need to provide a relatively small thrust to realize the movement of the moving magnetic member 61 to drive the driven assembly 50 to move, effectively saving the energy consumption of the door body assembly.

[0046] In this embodiment, the driving assembly 40 driving the moving magnetic member 61 to move along the magnetic acceleration channel 62 can be in the form of applying a thrust to the moving magnetic member 61, such as the driving assembly 40 hitting the moving magnetic member 61 to make the moving magnetic member 61 move, or in the form of driving the moving magnetic member 61 to move, such as the driving assembly 40 pushing against the moving magnetic member 61 to make it move.

[0047] According to an embodiment of the present utility model, in combination with Figure 1 and Figure 2 As shown, the magnetic transmission mechanism 60 further includes a plurality of magnetic components 63 arranged along the extending direction of the magnetic acceleration channel 62. The magnetic components 63 are arranged at intervals, and the magnetic fields of the magnetic components 63 constitute the magnetic acceleration channel 62. The magnetic fields of adjacent magnetic components 63 overlap. It can be understood that when the moving magnetic member 61 moves along the magnetic acceleration channel 62, between adjacent magnetic components 63, the magnetic fields of the prior and subsequent magnetic components 63 will both generate an attractive force on the moving magnetic member 61. Since the moving magnetic member 61 has a certain initial velocity, it can overcome the attractive force of the prior magnetic component 63 and be attracted by the attractive force of the subsequent magnetic component 63. Therefore, every time the moving magnetic member 61 passes through a magnetic component 63, the moving magnetic member 61 will obtain a certain acceleration.

[0048] In this embodiment, a total of nine magnetic components 63 are provided. In other embodiments, the number of magnetic components 63 can be adaptively adjusted based on the acceleration requirements.

[0049] According to an embodiment of the present utility model, in combination with Figure 1 and Figure 2As shown, the magnetic component 63 is an annular magnetic member 631, and a partial magnetic acceleration channel 62 is formed inside the inner ring of the annular magnetic member 631. A plurality of annular magnetic members 631 are coaxially arranged along the extending direction of the acceleration channel, and the south pole and north pole of the annular magnet are located on both sides of the annular magnetic member 631 along the extending direction. The inner ring of the annular magnetic member 631 can effectively limit the moving range of the moving magnetic member 61 and prevent it from detaching from the magnetic transmission mechanism 60 during the movement. The specific setting form can refer to the known technology (https: / / t.doruo.cn / 1j1OYePL2)

[0050] In another embodiment, the magnetic component 63 is a magnetic group, and the magnetic group includes magnetic parts symmetrically arranged on both sides of the extending direction of the magnetic acceleration channel 62. The south pole and north pole of the magnetic part are respectively located on both sides of the magnetic part along the extending direction of the magnetic acceleration channel 62. Its acceleration principle is the same as that of the annular magnetic member 631, which will not be elaborated here. The specific setting form can refer to the known technology (https: / / t.doruo.cn / 1j1Jj71Re).

[0051] In other embodiments, other structural forms that can realize the formation of the magnetic acceleration channel 62 can also be adopted.

[0052] In one embodiment, in combination with Figure 1 and Figure 2 As shown, along the extending direction of the magnetic acceleration channel 62, the interval of the magnetic component 63 gradually increases. The setting of the increasing interval makes the magnetic field intensity formed by the magnetic component 63 on one side of the starting end of the magnetic acceleration channel 62 always less than the magnetic field intensity formed by the magnetic component 63 on the terminating end side, with the moving magnetic member 61 as the boundary along the extending direction of the magnetic acceleration channel 62, ensuring that the moving magnetic member 61 can accelerate along the magnetic acceleration channel 62 without the moving magnetic member 61 staying stationary in the magnetic acceleration channel 62 due to the approaching magnetic field intensities on both sides of the moving magnetic member 61.

[0053] In one embodiment, along the extending direction of the magnetic acceleration channel 62, the magnetic field intensity of the magnetic component 63 gradually increases. Its principle is the same as the above-mentioned method of increasing the interval, that is, by controlling the magnetic field intensity to ensure that the moving magnetic member 61 can move from the starting end to the terminating end of the magnetic acceleration channel 62.

[0054] Of course, the gradual increase of the interval and the gradual increase of the magnetic field intensity can also be combined to further improve the acceleration effect of the moving magnetic member 61.

[0055] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2As shown, a detachable magnetic connection post 64 is arranged between adjacent magnetic components 63, which is suitable for fixing the distance between adjacent magnetic components 63. By changing the length of the magnetic connection post 64, the distance between different magnetic components 63 can be controlled, and the detachably arranged magnetic connection post 64 enables the flexible installation of the magnetic acceleration channel 62.

[0056] In other embodiments, the interval between the magnetic components 63 can also be controlled by setting a fixing groove for fixing the magnetic components 63 on the door panel 30 or the box door 10.

[0057] According to an embodiment of the present invention, in combination with Figure 2 As shown, when the magnetic component 63 is an annular magnetic part 631, the magnetic transmission mechanism 60 further includes at least two magnetic plates 65. The magnetic plates 65 extend along the extending direction and are magnetically attracted to the outer periphery of the annular magnetic part 631. By setting the magnetic plates 65, the coaxial arrangement of multiple annular magnetic parts 631 is ensured. The magnetic plates 65 are convenient to disassemble and install, effectively improving the installation efficiency.

[0058] In this embodiment, two separate magnetic plates 65 are provided. In other embodiments, the number of magnetic plates 65 can also be adaptively adjusted, or in the form of a V-shaped plate.

[0059] According to an embodiment of the present invention, in combination with Figure 2 As shown, the magnetic transmission mechanism 60 further includes a non-magnetic tube 66, which is suitable for the magnetic field of the magnetic component 63 to pass through. A moving magnetic part 61 is arranged inside the non-magnetic tube 66. Through the setting of the non-magnetic sleeve, it not only avoids the moving magnetic part 61 being adsorbed on the magnetic component 63 and unable to move, but also enables the magnetic acceleration channel 62 to be horizontally arranged to coincide with the relative movement direction of the door panel 30 and the box door 10, effectively improving the energy transfer effect of the moving magnetic part 61 driving the driven part to drive the door panel 30 to move.

[0060] Of course, in other embodiments, such as when the magnetic acceleration channel 62 is vertically arranged, the non-magnetic tube 66 may not be provided. Under the action of gravity, the moving magnetic part 61 can still move along the magnetic acceleration channel 62 without being adsorbed on the magnetic component 63.

[0061] According to an embodiment of the present invention, in combination with Figure 2 As shown, the driving component 40 includes an elastic member 41, which is suitable for switching between a compressed state and a popped state. In the popped state, the driving component 40 pushes the moving magnetic part 61.

[0062] The elastic member 41 can store elastic potential energy in the compressed state. In the popped state, the elastic potential energy can be converted into the initial kinetic energy of the moving magnetic part 61 to drive the moving magnetic part 61 to move along the magnetic acceleration channel 62.

[0063] In this embodiment, the movable magnetic member 61 can be in the form of a freely fixed connection with the elastic member 41, which facilitates resetting the movable magnetic member 61 to the starting end of the magnetic acceleration channel 62. Of course, it can also be in a non-connected form, in which case the free end of the elastic member 41 directly impacts the movable magnetic member 61 to drive its movement.

[0064] In other embodiments, the driving assembly 40 can also be a structure such as a lever or a push rod that can switch states and impart a certain initial kinetic energy to the movable magnetic member 61.

[0065] In this embodiment, a reset device such as a pull rod can also be provided to pull the free end of the elastic member 41 to switch it from the ejected state to the compressed state.

[0066] According to an embodiment of the present invention, in combination with Figure 1 and Figure 2 As shown, the driven assembly 50 includes a connecting rod 51 and a slider 52. The first end of the connecting rod 51 is adapted to contact the movable magnetic member 61 to enable the movable magnetic member 61 to drive the connecting rod 51 to move; the slider 52 is provided at the second end of the connecting rod 51, and the slider 52 is relatively fixed to the door panel 30 or the cabinet door 10.

[0067] In this embodiment, the movable magnetic member 61 impacts the first end of the connecting rod 51 of the driven assembly 50 after accelerating in the magnetic acceleration channel 62, transferring the kinetic energy to the connecting rod 51 to drive the slider 52 and the door panel 30 connected to the second section of the connecting rod 51 to move.

[0068] In another embodiment, when the driving assembly 40, the driven assembly 50, and the magnetic transmission mechanism 60 are provided on the door panel 30, the slider 52 on the connecting rod 51 is fixed to the cabinet door 10, and the relative movement effect between the cabinet door 10 and the door panel 30 can also be achieved.

[0069] In other embodiments, the driven assembly 50 can also be in the form of a gear, a worm, etc. The impact of the movable magnetic member 61 drives the gear to rotate to drive the worm to rotate, so that the door panel 30 engaged with the worm translates relative to the cabinet door 10.

[0070] According to an embodiment of the present invention, 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 driving assembly 40 and controls the movement of the driving assembly 40 based on the movement state of the door body assembly relative to the electrical appliance main body 20.

[0071] In this embodiment, the movement detected by the sensor 70 can be transmitted to the cylinder block of the transmission mechanism 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 in a relative relationship, and only uniqueness is required to control the state of the cylinder block. For example, the positive signal can be a high-level signal, and the negative signal can be a low-level signal.

[0072] In a specific embodiment, taking the example of a user opening the door body assembly, at this time, the sensor 70 detects the movement of the door body assembly and emits a positive signal. Based on the positive signal, the door body assembly controls the driving component 40 to work, so that the magnetic moving part 61 starts to move along the magnetic acceleration channel 62 from the starting end of the magnetic acceleration channel 62.

[0073] In this embodiment, the driving component 40 can be connected to the moving magnetic part 61 (such as the elastic part 41 is connected to the moving magnetic part 61). When the user closes the door body assembly, the sensor 70 emits a negative signal, and the driving component 40 can pull the moving magnetic part 61 back to the starting end along the magnetic acceleration channel 62 from the terminating end.

[0074] In this embodiment, the sensor 70 automatically detects the movement of the door body assembly relative to the electrical appliance main body 20 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.

[0075] In this embodiment, the door body assembly may further include a main control board 80 and a pre-buried wire (not shown in the figure). The main control board 80 is connected to the sensor 70 and the driving component 40 through the pre-buried wire, and the main control board 80 can control the driving component 40 to work based on the positive signal or negative signal fed back by the sensor 70.

[0076] In this embodiment, the sensor 70 can be an angle sensor, fixed to the box door 10 or the electrical appliance main body 20. During the opening and closing process of the door body assembly, an angle change occurs between the box door 10 and the electrical appliance main body 20 to generate a signal; of course, other types of sensors can also be used, such as a distance sensor, a speed sensor, etc., which are suitable for detecting the change of physical quantities during the relative movement of the door body assembly and the electrical appliance main body 20 and generating a signal.

[0077] The refrigeration device according to the second aspect embodiment of the present invention includes the door body assembly as described in the above embodiment.

[0078] The refrigeration device according to the embodiment of the present application has the same beneficial effects as the door body assembly in the first aspect embodiment of the present application, which will not be elaborated here.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Although the present utility model 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 utility model do not depart from the spirit and scope of the technical solutions of the present utility model, and should all be covered within the scope of the claims of the present utility model.
