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 appliance products 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, 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 results in 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, thus causing the door body assembly of the appliance to be unable to be opened or closed normally.

[0035] The following combines Figure 1 to describe the door body assembly and refrigeration equipment of this application.

[0036] The door assembly in the present application can be applied to household appliances, such as refrigerators. It is understood that the door assembly in the present application can also be applied to dishwashers, washing machines or any other suitable equipment. The refrigeration device in the present application is, for example, applied to refrigerators. It is understood that the refrigeration device in the present application can also be applied to freezers or any other suitable equipment.

[0037] According to the first embodiment of the utility model, the door assembly includes a door 10, a door panel 30 and a transmission mechanism. The door 10 is rotatably connected to the electrical appliance body 20, and the door 10 is suitable for opening or closing the storage space of the electrical appliance body 20; the door panel 30 is arranged on the outer side of the door 10, and the door panel 30 can slide along the width direction of the door 10; the transmission mechanism includes a first winding member 41 and a transmission component 42, the first end of the transmission component 42 is wound and connected to the first winding member 41, and the second end of the transmission component 42 can move relative to the first winding member 41; the first winding member 41 is arranged on one of the door 10 or the door panel 30, and the second end of the transmission component 42 is connected to the other, and the transmission mechanism is suitable for controlling the movement of the second end of the transmission component 42 through the winding movement of the first winding member 41, so as to realize the relative sliding of the door panel 30 and the door 10.

[0038] In this embodiment, a storage space is provided in the main body 20 of the electrical appliance for storing articles. The door panel 30 is a decorative panel on the outside of the door 10. The inner wall surface of the door panel 30 is spaced apart from the outer wall surface of the door 10. When the door assembly is in a closed state, the door 10 and the main body 20 of the electrical appliance are hidden on the side of the door panel 30 away from the user, thereby improving the aesthetics of the outer surface of the electrical appliance. The first winding member 41 can rotate by itself, so that the first end of the transmission component 42 can be wound on the first winding member 41, so as to shorten the length of the first winding member 41 in the width direction of the door 10, thereby shortening the distance between the first end and the second end of the transmission component 42, so that the second end of the transmission component 42 can drive the door panel 30 to move in a direction close to the first end of the transmission component 42, so as to achieve relative sliding of the door panel 30 and the door 10.

[0039] In this embodiment, the transmission mechanism is provided on the box door 10, and the second end of the transmission component 42 is connected to the door panel 30. Alternatively, the transmission mechanism can also be provided on the door panel 30, and the second end of the transmission component 42 is connected to the box door 10. The specific arrangement can be selected according to actual design requirements, as long as the relative sliding of the box door 10 and the door panel 30 can be achieved.

[0040] In this embodiment, the first winding member 41 is a wire reel, or other device capable of rolling up an object, for example, the first winding member 41 is a motor, and the output shaft of the motor is connected to the first end of the transmission member 42. In addition, the first winding member 41 is electrically controlled and can be controlled by the main control board of the electrical body 20.

[0041] According to the door body assembly of the embodiment of the present utility model, by driving the second end of the transmission component 42 to move by using the first winding member 41, the door panel 30 can move relative to the box door 10, and thus the relative sliding between the door panel 30 and the box door 10 can be realized. When the door body assembly is installed in an embedded manner, during the opening process of the door body assembly, the door panel 30 can always avoid the walls or plates on both sides in the width direction of the box door 10, and the interference between the door panel 30 and the external walls or plates can be avoided during the opening process of the door body assembly, so as to facilitate the normal opening or closing of the door body assembly. In addition, when the door body 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, thereby improving the aesthetics.

[0042] According to an embodiment of the present utility model, as Figure 1 shown, the transmission component 42 includes a translation rod 421 and a first flexible member 422. The translation rod 421 has a first side surface and a second side surface arranged oppositely in the width direction of the box door 10. The first end of the first flexible member 422 is wound and connected to the first winding member 41, and the second end of the first flexible member 422 is connected to the first side surface.

[0043] In this embodiment, the translation rod 421 is movable along the width direction of the box door 10. Both ends of the translation rod 421 are respectively arranged on the box door 10 and the door panel 30. The translation rod 421 is fixedly connected to one of the box door 10 and the door panel 30, and the translation rod 421 is slidably connected to the other of the box door 10 and the door panel 30. The first end of the first flexible member 422 being wound and connected to the first winding member 41 means that the first end of the first flexible member 422 can be wound up or released by the first winding member 41. For example, when the first winding member 41 rotates forward, a part of the first flexible member 422 is wound around the first winding member 41. When the first winding member 41 rotates in reverse, the part of the first flexible member 422 wound around the first winding member 41 is released by the first winding member 41. The first flexible member 422 is connected to the translation rod 421 through the first side surface. When the first winding member 41 winds up the first flexible member 422, the first flexible member 422 can drive the translation rod 421 to move in the direction of the first winding member 41, and further make the door panel 30 slide relative to the box door 10.

[0044] In this embodiment, the connection manner between the first flexible member 422 and the translation rod 421 is not limited as long as the first flexible member 422 can drive the translation rod 421 to move. For example, a pin with a through hole is arranged on the first side surface of the translation rod 421, and the first flexible member 422 passes through the through hole and is tied to the pin. Or, an annular groove is provided on the translation rod 421, and the first flexible member 422 is tied in the groove in a bundling form.

[0045] It should be noted that in this embodiment, the cross-sectional shape of the translation rod 421 is rectangular or circular. When the cross-sectional shape of the translation rod 421 is rectangular, the two opposite side surfaces of the translation rod 421 in the width direction of the door panel 10 are the first side surface and the second side surface; when the cross-sectional shape of the translation rod 421 is circular, the two opposite arc surfaces of the translation rod 421 in the width direction of the door panel 10 are the first side surface and the second side surface. In addition, in this embodiment, the first flexible member 422 includes, but is not limited to, components such as ropes and belts that can be bent and wound into a roll but cannot be stretched. Designers can select appropriate components as the first flexible member 422 according to actual design requirements.

[0046] Optionally, the first flexible member 422 is a rope.

[0047] According to the door body assembly of the embodiment of the present invention, by providing the translation rod 421 and the first flexible member 422, the sliding of the door panel 30 relative to the door panel 10 can be realized, so that the structure of the door body assembly is simple and convenient for processing.

[0048] According to an embodiment of the present invention, as Figure 1 shown, the transmission mechanism further includes a reset member 43. The first end of the reset member 43 is fixedly arranged relative to the first winding member 41, the second end of the reset member 43 is connected to the translation rod 421, and the reset member 43 is adapted to drive the translation rod 421 to move in a direction away from the first winding member 41 along the width direction of the door panel 10.

[0049] In this embodiment, in the width direction of the door panel 10, the reset member 43 can drive the translation rod 421 to move in a direction away from the first winding member 41, thereby driving the door panel 30 to move in a direction away from the first winding member 41, and further enabling the door panel 30 to return to the closed state. When it is necessary to open the storage space, the first winding member 41 winds up the first flexible member 422, thereby driving the door panel 30 to slide relative to the door panel 10, so that the door body assembly can be smoothly opened. When it is necessary to close the storage space, the reset member 43 works, so that the door panel 30 returns to the initial position.

[0050] It can be understood that in this embodiment, the setting manner of the reset member 43 is not limited. For example, the reset member 43 is in the form of an elastic member or a telescopic rod, etc., as long as the reset member 43 can move the door panel 30 in a direction away from the first winding member 41 in the width direction of the door panel 10.

[0051] According to the door body assembly of the embodiment of the present invention, by providing the reset member 43, the door panel 30 can be reset without manual operation by the user, thereby improving the convenience of the door body assembly. In addition, through the mutual cooperation of the transmission member 42 and the reset member 43, the automation degree of the door body assembly is improved.

[0052] According to an embodiment of the present utility model, as Figure 1 shown, the reset member 43 includes a second flexible member 432 and a second winding member 431. The first winding member 41 and the second winding member 431 are arranged on both sides of the translation rod 421 along the width direction of the door 10. The first end of the second flexible member 432 is connected to the second winding member 431, and the second end of the second flexible member 432 is fixedly connected to the second side surface.

[0053] In this embodiment, the second winding member 431 is arranged at the first end of the reset member 43, and the second flexible member 432 is arranged at the second end of the reset member 43.

[0054] The first winding member 41 and the second winding member 431 are respectively arranged on both sides of the translation rod 421, and the specific arrangement positions are arranged according to actual design requirements. The second flexible member 432 includes, but is not limited to, components such as ropes and belts that can be bent and wound into a roll but cannot be stretched. Designers can select a suitable component as the first flexible member 422 according to actual design requirements.

[0055] Optionally, the second flexible member 432 is the same as the first flexible member 422, which is convenient for processing. For example, both the second flexible member 432 and the first flexible member 422 are ropes.

[0056] In this embodiment, the second winding member 431 can adopt a reel or other devices that can wind up an object. For example, the second winding member 431 is a motor, and the output shaft of the motor is connected to the second flexible member 432. When the motor rotates, the second flexible member 432 can be wound around the output shaft of the motor or released by the output shaft. The second winding member 431 is electrically controlled and can be controlled by the controller of the electrical appliance main body 20. Optionally, the first winding member 41 and the second winding member 431 adopt the same device, which is convenient for processing.

[0057] In this embodiment, the connection manner of the second flexible member 432 and the translation rod 421 is not limited as long as the second flexible member 432 can drive the translation rod 421 to move. For example, a pin with a through hole is arranged on the second side surface of the translation rod 421, and the second flexible member 432 passes through the through hole and is tied to the pin. Or, an annular groove is arranged on the translation rod 421, and the second flexible member 432 is tied in the groove in a bundling form.

[0058] According to an embodiment of the present utility model, as Figure 1 shown, the translation rod 421 is provided with a first sliding portion, and the door panel 30 or the door 10 is correspondingly provided with a second sliding portion for the first sliding portion, and the first sliding portion can slide relative to the second sliding portion.

[0059] In this embodiment, the structures of the first sliding part and the second sliding part are not limited, as long as they can slide relative to each other. For example, the first sliding part is a chute or a slide rail, and the second sliding part is a slider that cooperates with the chute or the slide rail, or the first sliding part is a slider and the second sliding part is a chute or a slide rail.

[0060] In another embodiment, the first sliding part is provided on the door panel 30 or the door of the box 10, and the translation lever 421 is provided with a second sliding part corresponding to the first sliding part, and the first sliding part can slide relative to the second sliding part.

[0061] According to an embodiment of the present invention, as Figure 1 shown, the door body assembly further includes a first sensor 50. The first sensor 50 is adapted to detect the movement of the door body assembly relative to the electrical appliance main body 20. The first sensor 50 is connected to the transmission mechanism and controls the movement of the transmission mechanism based on the movement state of the door body assembly relative to the electrical appliance main body 20.

[0062] In this embodiment, the movement detected by the first sensor 50 can be transmitted to the first winding member 41 or the second winding member 431 of the transmission mechanism in the form of a signal. For example, when the first sensor 50 detects that the door body assembly is away from the electrical appliance main body 20, a positive signal can be sent, and when it detects that the door body assembly is approaching the electrical appliance main body 20, a negative signal can be sent. Here, the positive signal and the negative signal are not relative relationships, and only uniqueness is required to control the state of the first winding member 41 or the second winding member 431. For example, the positive signal can be a high-level signal, and the negative signal can be a low-level signal.

[0063] In a specific embodiment, when the user opens the door body assembly, the first sensor 50 detects that the door body assembly is away from the electrical appliance main body 20 and sends a positive signal. The transmission mechanism controls the rotation of the first winding member 41 and the second winding member 431 based on the positive signal. For example, at this time, the rotation directions of the first winding member 41 and the second winding member 431 are opposite. The first winding member 41 rotates forward to wind up the first flexible member 422, and the second winding member 431 rotates reversely to release the second flexible member 432 to cooperate with the movement of the first flexible member 422, so that the door panel 30 slides relative to the door of the box 10, thereby facilitating the user to open the door of the box 10. When the user closes the door body assembly, the first sensor 50 detects that the door body assembly is approaching the electrical appliance main body 20 and sends a negative signal. At this time, the transmission mechanism controls the rotation of the first winding member 41 and the second winding member 431 based on the negative signal. For example, the rotation directions of the first winding member 41 and the second winding member 431 are opposite. The second winding member 431 rotates forward to wind up the second flexible member 432, and the first winding member 41 rotates reversely to release the first flexible member 422 to cooperate with the movement of the second flexible member 432, so that the door panel 30 is reset, thereby facilitating the user to close the door body assembly.

[0064] In this embodiment, the first sensor 50 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 cabinet door 10 and ensuring the safety of the movement of the door panel 30. And by changing the parameters of the transmission mechanism, for example, by controlling the rotation speed of the first winding member 41 or the second winding member 431, the movement speed of the door panel 30 relative to the cabinet door 10 is controlled, so as to effectively adapt to the requirements in different situations.

[0065] 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 first sensor 50 and the transmission mechanism through the pre-buried wire, and the main control board can control the operation of the transmission mechanism based on the positive signal or negative signal fed back by the first sensor 50.

[0066] In this embodiment, the first sensor 50 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. Of course, other types of sensors can also be used, such as an angle sensor, a speed sensor, etc., which are suitable for detecting the change of physical quantities when the door body assembly and the electrical appliance main body 20 move relative to each other and generating a signal.

[0067] According to an embodiment of the present invention, as Figure 1 shown, a handle 31 is provided on the side of the door panel 30 facing away from the cabinet door 10. Thus, it is convenient for pulling the door panel 30.

[0068] According to an embodiment of the present invention, as Figure 1 shown, a second sensor 32 is provided on the handle 31. The second sensor 32 is connected to the first sensor 50, and the second sensor 32 is suitable for detecting the touch action of the user.

[0069] In this embodiment, the side of the door panel 30 facing away from the cabinet door 10 is the outer side surface of the door panel 30. A second sensor 32 is provided on the outer side surface of the door panel 30. The second sensor 32 is a touch sensor, and the specific type of the second sensor 32 is not limited as long as it can emit a signal when the user touches or releases the handle 31. For example, the second sensor 32 is an infrared touch sensor or a capacitive touch sensor.

[0070] In a specific embodiment, when the user needs to open the storage space, first, when the user pulls the handle 31, the second sensor 32 is touched. The second sensor 32 sends a touch signal to the first sensor 50. After the first sensor 50 detects the distance between the door 10 and the electrical appliance main body 20, it is sent to the controller of the main control board. The controller detects whether the distance value is a first preset value. For example, the first preset value is set to zero. When the controller determines that the distance value is zero, it controls the transmission mechanism to operate so that the door panel 30 slides to a preset position. Then the user continues to pull the handle 31 to open the storage space.

[0071] When the user needs to close the storage space, first, the first sensor 50 continuously detects the real-time distance between the door 10 and the electrical appliance main body 20. When the controller determines that the real-time distance at a certain moment is less than or equal to a second preset value, the controller controls the transmission mechanism to operate so that the door panel 30 slides back to the closed position.

[0072] According to an embodiment of the present invention, as Figure 1 shown, the transmission mechanism is arranged at the top of the door panel 30 or the door 10. Thus, it is convenient for the staff to repair and replace the components of the transmission mechanism, improving the maintenance and installation efficiency.

[0073] The refrigeration device according to the second aspect embodiment of the present invention includes the door body assembly described in any one of the above embodiments.
