Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and more particularly to a double-door refrigerator with a sealing structure. Background Technology

[0002] Refrigerators are common household appliances. Large-capacity refrigerators usually adopt a side-by-side door design, which ensures a large internal storage space while reducing the space occupied during the opening and closing of the door.

[0003] For side-by-side refrigerators, a central vertical beam is typically installed inside the refrigerator to ensure a better seal between the door and the cabinet, allowing it to be fitted to the inside of the door with a sealing strip. However, this central vertical beam reduces the refrigerator's internal storage space, thus decreasing its internal volume. Utility Model Content

[0004] This application provides a side-by-side refrigerator with a sealing structure to solve the problem that the sealing structure of the side-by-side refrigerator door will occupy internal storage space.

[0005] On one hand, some embodiments of this application provide a double-door cabinet with a sealing structure, including a cabinet body, a first door, a second door, a telescopic beam, an electric drive unit, two positioning members, and at least two first sealing strips. The first and second doors are hinged to the cabinet body and are configured as a double-door structure. The telescopic beam is connected to the first door and is configured to move and switch between a first state position and a second state position. When the first and second doors are in a closed state and the cabinet is closed, the telescopic beam extends toward the second door to the first state position to fill the gap between the first and second doors. The electric drive unit is disposed in the first door body and connected to the telescopic beam to drive the telescopic beam to move and switch between the first and second state positions.

[0006] Along the length of the telescopic beam, two positioning elements are spaced apart and connected to the cabinet. Along the length of the telescopic beam, a first sealing strip is connected to the inner sides of the positioning elements that are close to each other. When the first and second doors are closed, the first sealing strip contacts the end of the telescopic beam along its length.

[0007] Optionally, the telescopic beam includes a second sealing strip and a first telescopic plate frame. The first telescopic plate frame is slidably connected to the first door body and connected to an electric drive component. The second sealing strip is connected to the side of the first telescopic plate frame away from the electric drive component, so as to drive the second sealing strip to switch between a first state position and a second state position.

[0008] Optionally, the telescopic beam further includes at least two first limiting members, which are connected to the side of the first telescopic frame away from the second sealing strip, and the at least two first limiting members are spaced apart along the length of the first telescopic frame. The first door body is provided with at least two first limiting holes corresponding to the first limiting members, and one first limiting member is inserted into and adapted to one first limiting hole, so that the first telescopic frame can move and switch between a first state position and a second state position along the axial direction of the first limiting hole.

[0009] Optionally, the double-door housing with a sealing structure also includes a third sealing strip. The third sealing strip is set corresponding to the telescopic beam and connected to the second door. When the telescopic beam is in the first state position, the telescopic beam and the third sealing strip are pressed into contact.

[0010] Optionally, the double-door enclosure with a sealing structure further includes a second telescopic plate, at least two second limiting members, and at least two elastic members. The second telescopic plate has at least two second limiting holes, which are spaced apart along the length of the second telescopic plate. One second limiting member is connected to the second door body through one second limiting hole to prevent the second telescopic plate from detaching from the second door body. One elastic member is inserted into and fitted with one of the second limiting members. Along the length of the second limiting member, the elastic member is located between the second telescopic plate and the second door body and is in a compressed state. A third sealing strip is connected to the side of the second telescopic plate away from the elastic member.

[0011] Optionally, the first door body is provided with a first positioning groove, and the telescopic beam is disposed in the first positioning groove and used to switch between a first state position and a second state position.

[0012] Optionally, the second door body is provided with a second positioning groove, and at least the second telescopic plate frame is located in the second positioning groove.

[0013] Optionally, the double-door enclosure with a sealed structure also includes a switch module and a main control circuit. The switch module is the operating terminal, and outputs a first-level signal when operated. The main control circuit is electrically connected to the switch module and the electric drive component. The main control circuit receives the first-level signal and controls the electric drive component to move the telescopic beam from a first state position to a second state position.

[0014] Optionally, the double-door housing with a sealing structure also includes a position sensor. The position sensor is used to detect the position status of the first door and the second door. When the first door and the second door are in the closed state, the position sensor outputs a second level signal. The position sensor is electrically connected to the main control circuit, which receives the second level signal and controls the electric drive component to move the telescopic beam to the first state position.

[0015] Optionally, the double-door cabinet with a sealed structure further includes a signal detection component. The signal detection component includes a compartment light and a detection circuit. The compartment light is located inside the cabinet, and the detection circuit is electrically connected to the compartment light and the main control circuit. When at least one of the first and second doors is open, the compartment light is configured to illuminate. When the first and second doors are closed, the compartment light is configured to turn off, and the detection circuit outputs a third-level signal. The main control circuit receives the third-level signal and controls the electric drive component to move the telescopic beam to the first position.

[0016] Optionally, the electric drive component is a linear motor. On the other hand, some embodiments of this application also provide a refrigerator, including a double-door cabinet with a sealed structure as described above, and a refrigeration circuit for cooling the interior space of the cabinet.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] By incorporating the telescopic beam and electric drive mechanism, when the first and second doors are in the closed state to seal the interior space of the cabinet, the electric drive mechanism can be manually controlled or configured as an automatic control structure to move the telescopic beam from the second position to the first position. In this way, the electric drive mechanism causes the telescopic beam to extend towards the second door and move to the first position, allowing the telescopic beam to contact or adhere to the side wall or other sealing structure of the second door. This seals and fills the gap between the first and second doors, ensuring a good sealing effect on the interior space of the cabinet when the first and second doors, arranged in a double-door configuration, are closed.

[0019] Compared to related technologies that involve installing a central vertical beam within the cabinet, the telescopic beam used in this application for sealing the gaps in the double doors only needs to be installed at the first door, eliminating the need for additional space within the cabinet and thus increasing internal storage space. Furthermore, during the process of the first and second doors rotating to their closed positions and the telescopic beam moving to its first position, the movement of the telescopic beam is driven by an electrically driven component, preventing any resistance to the rotation and closure of the first and second doors, resulting in a better user experience.

[0020] Meanwhile, when the first and second doors are closed, due to the gap between the telescopic beam and the cabinet frame, the positioning element and the first sealing strip allow the positioning element and the telescopic beam to be sealed by contacting the upper and lower end faces of the telescopic beam through the first sealing strip, thereby reducing or eliminating the gap between them, so that the cabinet and the first and second doors have a better sealing effect, and the cabinet interior has better airtightness.

[0021] Taking the application of a side-by-side refrigerator as an example, the gap between the door and the cabinet is filled with a telescopic beam and a first sealing strip to improve the sealing effect. This can reduce or avoid the leakage of cold air inside the cabinet, save energy and protect the environment, and solve the problem of condensation caused by cold air at the leakage location, resulting in a better user experience.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0049] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0051] Please see Figures 1 to 13 This application provides a side-by-side refrigerator with a sealing structure to solve the problem that the sealing structure of the side-by-side refrigerator door will occupy internal storage space.

[0052] like Figure 1 and Figure 2 As shown, the refrigerator includes a double-door cabinet with a sealing structure (hereinafter referred to as the double-door cabinet 100). The double-door cabinet 100 includes a cabinet 110, a first door 120 and a second door 130. The first door 120 and the second door 130 are hinged to the cabinet 110 and are configured as a double-door structure for opening or closing the internal space (i.e., storage compartment) inside the cabinet 110.

[0053] Combination Figure 3 The refrigerator also includes a refrigeration circuit 200, which comprises a compressor 210, a condenser 220, a throttling device 230, an evaporator 240, and the compressor 210 connected in sequence. The compressor 210 compresses the refrigerant and provides power, causing the refrigerant to liquefy and release heat in the condenser 220. After the liquefied refrigerant is depressurized by the throttling device 230, it absorbs heat and vaporizes in the evaporator 240. The vaporized refrigerant finally enters the compressor 210 through the return port to be circulated and compressed.

[0054] Thus, by setting up fans and air ducts to drive air to circulate between the evaporator 240 and the internal space of the cabinet 110, air is used to cool the storage compartments, thereby forming an air-cooled refrigerator. Depending on the amount of air circulation and the cooling effect of different evaporators 240, storage compartments with multiple temperature ranges, such as refrigerator compartments, freezer compartments, soft-freeze compartments, and variable temperature compartments, can be formed.

[0055] Alternatively, the evaporator 240 can be configured as a coil structure, and the coil structure can be located on the side wall of the storage compartment, or the coil structure can be located inside the storage compartment, so that the storage compartment is directly cooled by the refrigerant that evaporates and vaporizes in the coil structure, thereby forming a direct-cooling refrigerator.

[0056] For example, in the double-door cabinet 100, the double-door structure can be provided only at the opening of one of the storage compartments. Figure 1 As shown, the storage compartment above the cabinet 110 has a double door structure, and the two storage compartments below the cabinet 110 can be set as single-leaf hinged door structures or sliding drawer structures.

[0057] Alternatively, the cabinet 110 may include two storage compartments spaced apart, with the upper storage compartment having a double-door structure and the lower storage compartment also having a double-door structure, such as a refrigerator with a cross-door structure.

[0058] like Figure 4 As shown, the double-door housing 100 also includes a telescopic beam 140 and an electric drive unit 150. The telescopic beam 140 is connected to the first door 120 and configured to move and switch between a first state position and a second state position. When the first door 120 and the second door 130 are in... Figure 2 When the cabinet 110 is closed as shown, such as Figure 5 As shown, the telescopic beam 140 extends toward the second door 130 to a first position to fill the gap between the first door 120 and the second door 130. An electric drive unit 150 is disposed within the first door 120 and connected to the telescopic beam 140 to drive the telescopic beam 140 to switch between the first and second positions.

[0059] The second state position is either the telescopic beam 140 being away from the second door 130 or the telescopic beam 140 retracted to the first door 120. In this state, the telescopic beam 140 does not fill the gap between the first door 120 and the second door 130, or reduces the degree of filling, so that it will not be obstructed when the first door 120 or the second door 130 is rotated to open the internal space of the cabinet 110.

[0060] Thus, through the arrangement of the telescopic beam 140 and the electric drive unit 150, when the first door 120 and the second door 130 are moved to the closed state to seal the internal space of the cabinet 110, the electric drive unit 150 can be manually controlled, or configured as an automatic control structure, to drive the telescopic beam 140 from the second state position to the first state position. In this way, the electric drive unit 150 drives the telescopic beam 140 to extend towards the second door 130 and move to the first state position, so that the telescopic beam 140 contacts or adheres to the side wall or other sealing structure of the second door 130, thereby sealing and filling the gap between the first door 120 and the second door 130. This ensures that the first door 120 and the second door 130, which are configured as double doors, provide a better sealing effect for the internal space of the cabinet 110 when closed.

[0061] Compared to related technologies that involve installing a central vertical beam within the cabinet 110, the telescopic beam 140 used for sealing the gaps in the double doors in this application only needs to be installed at the first door 120, without occupying additional space within the cabinet 110, thus increasing the internal storage space of the cabinet 110. Furthermore, during the process of the first door 120 and the second door 130 rotating to the closed state until the telescopic beam 140 moves to the first position, the movement of the telescopic beam 140 is driven by the electric drive component 150, which does not create resistance to the rotation and closing of the first door 120 and the second door 130, resulting in a better user experience.

[0062] Based on this, such as Figure 6 and Figure 7 As shown, the double-door cabinet 100 also includes two positioning members 161 and at least two first sealing strips 162. Along the length of the telescopic beam 140, the two positioning members 161 are spaced apart and connected to the cabinet body 110. Taking the telescopic beam 140 as an example where the length direction is vertical, one positioning member 161 is provided at each of the upper and lower edges of the cabinet body 110. Along the length direction of the telescopic beam 140, the first sealing strips 162 are connected to the inner sides of the positioning members 161 that are close to each other. At least one first sealing strip 162 is installed at each positioning member 161. When the first door 120 and the second door 130 are in the closed state, the first sealing strips 162 contact the ends (such as the upper and lower ends) of the telescopic beam 140 along its length direction.

[0063] When the first door 120 and the second door 130 are in the closed state, such as Figure 6 and Figure 7As shown, since there is a gap between the telescopic beam 140 and the frame of the cabinet 110, the positioning member 161 and the first sealing strip 162 are provided so that the positioning member 161 and the telescopic beam 140 can be sealed by the first sealing strip 162 contacting the upper and lower end faces of the telescopic beam 140, thereby reducing or eliminating the gap between them, so that the cabinet 110 has a better sealing effect with the first door 120 and the second door 130, and the cabinet 110 has better airtightness.

[0064] Taking the side-by-side cabinet 100 as an example in a refrigerator, the gap between the door and the cabinet 110 is filled by the telescopic beam 140 and the first sealing strip 162 to improve the sealing effect. This can reduce or avoid the leakage of cold air inside the cabinet 110, which is energy-saving and environmentally friendly. It can also solve the problem of condensation caused by cold air at the leakage location, resulting in a better user experience.

[0065] It should be noted that the double-door cabinet 100 provided in this application embodiment can be adapted to the refrigeration circuit 200 to achieve refrigeration or freezing, thereby meeting the purpose of low-temperature storage of items. Alternatively, the double-door cabinet 100 can also be applied to structures or devices with sealing requirements such as cabinets, wardrobes, or dishwashers, and there is no limitation thereto.

[0066] To improve the sealing and filling effect at point 140 of the telescopic beam, such as Figure 4 and Figure 5 As shown, the telescopic beam 140 includes a second sealing strip 141 and a first telescopic plate frame 142. The first telescopic plate frame 142 is slidably connected to the first door body 120. The first telescopic plate frame 142 is connected to the electric drive unit 150. The side of the first telescopic plate frame 142 away from the electric drive unit 150 is connected to the second sealing strip 141 so as to drive the second sealing strip 141 to switch between a first state position and a second state position.

[0067] When the telescopic beam 140 is in the first position, the second sealing strip 141 increases the contact area between the telescopic beam 140 and the second door 130 or other sealing structures, thereby reducing gaps and improving the sealing effect. While the first telescopic frame 142 moves the second sealing strip 141 between the first and second positions, it also ensures good parallelism of the second sealing strip 141 along its length in the first position, providing better support and thus improving the sealing effect.

[0068] The first telescopic frame 142 is a strip structure, a sheet structure, or a rod structure. When the telescopic beam 140 extends to the first state position, the exposed first telescopic frame 142 can cover and fill the gap between the first door body 120 and the second door body 130.

[0069] When connecting and installing the telescopic beam 140 and the first door body 120, such as Figure 4 and Figure 8 As shown, the telescopic beam 140 also includes at least two first limiting members 143, which are connected to the side of the first telescopic frame 142 away from the second sealing strip 141. That is, the first limiting members 143 and the electric drive unit 150 are connected to the same side of the first telescopic frame 142. The at least two first limiting members 143 are spaced apart along the length of the first telescopic frame 142. The first door body 120 is provided with at least two first limiting holes 122 corresponding to the first limiting members 143. One first limiting member 143 is inserted into and adapted to one first limiting hole 122, so that the first telescopic frame 142 can move and switch between a first state position and a second state position along the axial direction of the first limiting hole 122. Through the insertion and adaptation of the first limiting members 143 and the first limiting holes 122, the telescopic beam 140 can switch and move in a straight line between the first state position and the second state position.

[0070] It should be noted that the electric drive unit 150 may include a drive motor, a crank wheel assembly, and a transmission connecting rod. Both ends of the transmission connecting rod are rotatably connected to the output end of the crank wheel assembly and the first telescopic plate frame 142. The drive motor drives the crank wheel assembly to rotate, enabling the output end of the crank wheel assembly to rotate circumferentially. Simultaneously, the circumferentially moving output end drives the first telescopic plate frame 142 to switch between a first state position and a second state position via the transmission connecting rod.

[0071] The aforementioned drive motor can be a stepper motor or a servo motor, which drives the telescopic beam 140 to switch between a first state position and a second state position along the first limiting hole 122 through a precise rotation angle.

[0072] Alternatively, the electric drive component 150 can be a linear motor, such as a flat linear motor, a U-shaped linear motor, a shaft linear motor, or a tubular linear motor. The output end of the linear motor can extend and retract axially along the first limiting hole 122, thereby driving the first telescopic frame 142 to switch between a first state position and a second state position. This design offers advantages such as compact structure, fewer parts, and ease of maintenance.

[0073] Thus, through the connection of the electric drive component 150, during the process of driving the telescopic beam 140 to switch between the first state position and the second state position, the first telescopic plate frame 142 and the electric drive component 150 are connected by means of pins, screws or rivets, so as to prevent the telescopic beam 140 from extending along the axis of the first limiting hole 122 toward the first state position and detaching from the first door body 120.

[0074] In the above scheme, the first limiting member 143 can be an adapted plug rod. During the process of the first telescopic plate frame 142 switching between the first state position and the second state position, the first limiting member 143 can reciprocate axially within the first limiting hole 122.

[0075] Alternatively, the first limiting member 143 can be configured as a screw structure. That is, the first telescopic plate 142 has a through-hole corresponding to the first limiting hole 122, which is a threaded hole. The first limiting member 143 connects to the first limiting hole 122 via the through-hole along the axial direction of the first limiting hole 122, from the side of the first telescopic plate 142 towards the second sealing strip 141. This allows the first telescopic plate 142 to switch between a first state position and a second state position relative to the first limiting member 143 along the axial direction of the first limiting hole 122.

[0076] like Figure 8 and Figure 9 As shown, the first door body 120 is provided with a first positioning groove 121, and the telescopic beam 140 is disposed in the first positioning groove 121 and is used to switch between the first state position and the second state position.

[0077] For example, the first limiting hole 122 is located at the bottom wall of the first positioning groove 121. This is achieved by opening the first positioning groove 121 on the first door body 120 and placing the first telescopic plate frame 142 within the first positioning groove 121. Figure 9 As shown, the first telescopic plate frame 142 is located in the first positioning groove 121 and is in the second state position, thereby preventing the protruding arrangement of the telescopic beam 140 from affecting the smoothness of opening and closing of the first door 120. At this time, the second sealing strip 141 can be partially located in the first positioning groove 121 or completely located in the first positioning groove 121, as long as it does not affect the opening and closing of the first door 120, there is no limitation on this.

[0078] like Figure 10 As shown, driven by the electric drive unit 150, the first telescopic plate frame 142 drives the second sealing strip 141 to extend out of the first positioning groove 121, for contacting the second door body 130 or other sealing structures. At this time, the second sealing strip 141 is fully extended out of the first positioning groove 121, and the first telescopic plate frame 142 is partially extended out of the first positioning groove 121 and in the first state position. At this time, the first telescopic plate frame 142 is in contact with the inner and outer side walls of the first positioning groove 121 to reduce the leakage gap between the telescopic beam 140 and the first door body 120, thereby improving the overall sealing effect between the first door body 120 and the second door body 130.

[0079] To further improve the sealing effect between the first door body 120 and the second door body 130, such as... Figure 5 and Figure 11As shown, the double-door housing 100 also includes a third sealing strip 171, which is disposed corresponding to the telescopic beam 140 and connected to the second door 130. (Refer to...) Figure 10 When the telescopic beam 140 is in the first position, the telescopic beam 140 is pressed into contact with the third sealing strip 171. That is, the third sealing strip 171 is pressed and adhered to the second sealing strip 141 to improve the sealing and filling effect of the gap between the first door body 120 and the second door body 130.

[0080] It should be noted that when the telescopic beam 140 is in the first position, the second sealing strip 141 and the third sealing strip 171 achieve a good sealing effect through compression. Therefore, when connecting the first telescopic plate frame 142 and the electric drive component 150, there is no need to set a buffer structure directly between them; a good buffering effect can be achieved through the elastic compression between the third sealing strip 171 and the second sealing strip 141, resulting in a simple structure.

[0081] Furthermore, to further improve the buffering effect of the telescopic beam 140 in the first state position, such as... Figure 5 and Figure 11 As shown, the double-door cabinet 100 also includes a second telescopic plate frame 172, at least two second limiting members 173, and at least two elastic members 174. Combined with... Figure 10 The second telescopic panel 172 is provided with at least two second limiting holes 175, which are spaced apart along the length of the second telescopic panel 172. A second limiting member 173 is connected to the second door body 130 through one of the second limiting holes 175 to prevent the second telescopic panel 172 from detaching from the second door body 130. An elastic member 174 is inserted and fitted to one of the second limiting members 173. Along the length of the second limiting member 173, the elastic member 174 is located between the second telescopic panel 172 and the second door body 130 and is in a compressed state. A third sealing strip 171 is connected to the side of the second telescopic panel 172 away from the elastic member 174.

[0082] The second telescopic frame 172 is connected to the second door body 130 by the second limiting member 173, so that the second telescopic frame 172 can slide relative to the second door body 130 along the length direction of the second limiting member 173. Furthermore, an elastic member 174 in a compressed state is provided between the second telescopic frame 172 and the second door body 130, so that the second telescopic frame 172 drives the third sealing strip 171 to remain in an outwardly extended state.

[0083] When the first door 120 and the second door 130 are in the closed state, and the first telescopic plate 142 drives the second sealing strip 141 to move to... Figure 10In the first state position shown, the first telescopic plate 142 can press the third sealing strip 171 and the second telescopic plate 172 to the left by the second sealing strip 141 to increase the contact area between the second sealing strip 141 and the third sealing strip 171, thereby improving the sealing and filling effect between the first door body 120 and the second door body 130.

[0084] Thus, there is no need to configure a buffer structure between the telescopic beam 140 and the electric drive unit 150. The telescopic beam 140 can contact and buffer with the second telescopic plate frame 172 to improve the stability of the sealing assembly.

[0085] Based on this, such as Figure 10 and Figure 11 As shown, the second door body 130 is provided with a second positioning groove 131, and at least the second telescopic plate frame 172 is located in the second positioning groove 131.

[0086] By creating a second positioning groove 131 on the second door body 130 and placing the second telescopic plate 172 within the second positioning groove 131, the second telescopic plate 172 contacts the inner and outer side walls of the second positioning groove 131. This reduces leakage gaps between the second telescopic plate 172 and the second door body 130, ensuring a better seal between the second telescopic plate 172 and the second door body 130 during the compression and movement of the third sealing strip 171. This improves the overall sealing effect between the first door body 120 and the second door body 130.

[0087] In some embodiments, such as Figure 8 As shown, the telescopic beam 140 also includes a first magnetic strip 144, and a second sealing strip 141 contains one or more first magnetic strips 144.

[0088] When the first door 120 and the second door 130 are in the closed state, the second sealing strip 141, when extended to the first state position, can contact and adhere to the metal door frame of the second door 130 or the third sealing strip 171 through the first magnetic strip 144, so as to increase the contact and adhesion area through the magnetic attraction provided by the first magnetic strip 144, thereby further improving the sealing effect between the first door 120 and the second door 130.

[0089] Correspondingly, the third sealing strip 171 can be filled with a magnetic medium to accommodate the first magnetic strip 144 at the second sealing strip 141. Alternatively, a second magnetic strip can be provided inside the third sealing strip 171 to increase the contact area between the second sealing strip 141 and the third sealing strip 171 through the magnetic attraction between the first magnetic strip 144 and the second magnetic strip.

[0090] It should be noted that this applies when the double-door box 100 is equipped with both a telescopic beam 140 and a second telescopic plate frame 172.

[0091] like Figure 12 As shown, when the first door and the second door are in the closed state, along the length direction of the first telescopic frame 142, the first sealing strips 162 located on both sides of the first telescopic frame 142 simultaneously contact and seal the two end faces of the first telescopic frame 142 and the second telescopic frame 172. This reduces the gaps between the second telescopic frame 172 and the first telescopic frame 142 and the cabinet 110, thereby improving the sealing and filling effect between the first door 120 and the second door 130.

[0092] In some embodiments, such as Figure 13 As shown, the double-door housing 100 also includes a switch module 181 and a main control circuit 182. The switch module 181 is the operating terminal and outputs a first-level signal when operated. The main control circuit 182 is electrically connected to the switch module 181 and the electric drive unit 150. The main control circuit 182 is used to receive the first-level signal and control the electric drive unit 150 to move the telescopic beam 140 from the first state position to the second state position.

[0093] When the first door 120 and the second door 130 are in the closed state, and the telescopic beam 140 is in the first state position, there is a large compressive force between the telescopic beam 140 and the second door 130. While maintaining a good sealing effect, this will affect the smooth opening of the first door 120 and the second door 130.

[0094] At this time, through the configuration of the switch module 181 and the main control circuit 182, the user can operate the switch module 181 to control the telescopic beam 140 to retract from the first state position to the second state position. Subsequently, the user can freely open the first door 120 or the second door 130.

[0095] For example, the switch module 181 can be a button switch, a touch switch, or a switch operation position built into a touch screen module, and there is no limitation thereto.

[0096] It should be noted that in the event of a power outage or other component failure, the telescopic beam 140 can maintain its initial position, i.e., the first state position, so that the side-by-side cabinet 100 (especially the refrigerator) can maintain a good sealing effect.

[0097] At this time, if it is necessary to open the first door 120 and the second door 130, the first door 120 and the second door 130 can be opened by rotating them simultaneously, or the first door 120 and the second door 130 can be closed by rotating them simultaneously, and the telescopic beam 140 and the third sealing strip 171 are aligned when the door is in the closed state, so as to meet the opening operation in emergency scenarios.

[0098] To facilitate the control of the telescopic beam 140's position by the main control circuit 182. For example... Figure 13 As shown, the double-door housing 100 also includes a position sensor 183, which is used to detect the position status of the first door 120 and the second door 130. The position sensor 183 can be a squeeze touch controller or a photoelectric position sensor. Each door can be equipped with at least one position sensor to detect the position status of the first door 120 and the second door 130.

[0099] When the first door 120 and the second door 130 are in the closed state, the position sensor 183 outputs a second level signal. Alternatively, the position sensor 183 can be configured for dual-end detection, meaning it will only output the second level signal when both the first door 120 and the second door 130 are simultaneously detected to be in the closed state.

[0100] Position sensor 183 is electrically connected to main control circuit 182. Main control circuit 182 receives a second-level signal and controls electric drive component 150 to move telescopic beam 140 to the first state position. This achieves automatic control and sealing of telescopic beam 140.

[0101] Alternatively, two position sensors 183 can be set for the first door 120 and the second door 130. When both position sensors 183 output the second level signal, the main control circuit 182 controls the electric drive unit 150 to move the telescopic beam 140 to the first state position after receiving the two second level signals.

[0102] In some embodiments, a refrigerator with a side-by-side door configuration 100 is taken as an example. Figure 13 As shown, the double-door cabinet 100 also includes a signal detection component 184, which includes a compartment light 1841 and a detection circuit 1842. The compartment light 1841 is disposed inside the cabinet 110, and the detection circuit 1842 is electrically connected to the compartment light 1841 and the main control circuit 182. When at least one of the first door 120 and the second door 130 is opened, the compartment light 1841 is configured to be turned on.

[0103] When the first door 120 and the second door 130 are in the closed state, the room light 1841 is configured to be off, and the detection circuit 1842 outputs a third level signal. The main control circuit 182 is used to receive the third level signal and control the electric drive unit 150 to drive the telescopic beam 140 to move to the first state position.

[0104] It should be noted that the compartment light 1841 is a standard feature inside the refrigerator and is linked to the corresponding compartment door. When one of the doors is open, the compartment light 1841 illuminates to facilitate the user's access to items within that compartment. When all the corresponding compartment doors are closed, the compartment light 1841 turns off, saving energy. Thus, a detection circuit 1842 monitors the operating status (e.g., on / off state) of the compartment light 1841. When the compartment light 1841 is de-energized, a third-level signal is output, causing the main control circuit 182 to control the electric drive unit 150 to move the telescopic beam 140 to the first position, thereby closing the first door 120 and the second door 130.

[0105] While achieving automatic control and sealing of the telescopic beam 140, it can be adapted to existing components, which helps to simplify the number of components and improve the compatibility of the whole system.
