Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a refrigerator. Background Technology

[0002] The central beam of a household refrigerator is mainly located between the doors. Currently, most refrigerators have a flip-up central beam to ensure the airtightness of the refrigerator's interior and thus guarantee the cooling effect. However, because the central beam is located at the door gap, it is in direct contact with the cold air inside the refrigerator and the outside, making it very prone to condensation. Existing refrigerator central beam technology can only keep the door gaps cold and does not address the condensation on the central beam itself. Summary of the Invention

[0003] In order to solve the technical problem that the moving beam of the refrigerator in the prior art cannot be used for condensation treatment, the present invention proposes a refrigerator.

[0004] The technical solution adopted in this invention is:

[0005] This invention proposes a refrigerator, comprising:

[0006] A telescopic central beam is installed on the first refrigerator door. When the telescopic central beam is extended, it blocks the gap between the first refrigerator door and the second refrigerator door. When it is retracted, it scrapes against the condensation on the outside of the telescopic central beam.

[0007] A guide rail is provided at the inner edge of the first refrigerator door along the length of the refrigerator door, and a drive assembly that can move along the guide rail to compress the telescopic beam is provided on the guide rail.

[0008] The controller controls the extension or retraction of the telescopic beam based on the refrigerator door opening / closing signal and the humidity signal inside the refrigerator.

[0009] Furthermore, the telescopic middle beam includes:

[0010] A base, which is mounted on the guide rail;

[0011] Multiple sleeves are arranged in ascending order of size, with the largest sleeve fixed to the base at the bottom. Each sleeve has a first retaining ring on the inner side of its top and a second retaining ring on the outer side of its bottom. When the telescopic beam retracts, the extended sleeves are retracted into the largest sleeve. When it extends, other sleeves are extended outward from the largest sleeve, and the first and second retaining rings of adjacent sleeves are engaged.

[0012] A spring is disposed inside the smallest sleeve, with one end abutting the base and the other end abutting the first retaining ring inside the smallest sleeve. When the spring unfolds, it causes the sleeve to extend.

[0013] Furthermore, the base of the telescopic beam is equipped with an electromagnetic switch, which locks the compressed spring when the electromagnetic switch is de-energized and releases the spring when the electromagnetic switch is energized.

[0014] Furthermore, the base is equipped with a door switch for detecting the door's open / close status and issuing open / close signals;

[0015] When the controller receives the door opening signal, it controls the telescopic beam to retract and scrape the condensation on the telescopic beam; when the controller receives the door closing signal, it controls the telescopic beam to extend and block the gap between the two refrigerator doors.

[0016] Furthermore, when the number of times the refrigerator door is opened and closed within a preset time period is less than a preset number, and the humidity sensor inside the refrigerator detects that the humidity is greater than a preset humidity, the controller drives the drive assembly to retract the telescopic beam to scrape the condensation on the telescopic beam, and then controls the electromagnetic switch to be energized, so that the spring is released and the telescopic beam is extended.

[0017] Furthermore, the telescopic beam also includes a pad block disposed at the top of the first sleeve.

[0018] Furthermore, the drive assembly and the telescopic beam are provided in two sets, the two sets of drive assemblies are respectively located at both ends of the guide rail, and the bases of the two sets of telescopic beams are arranged back to back in the middle of the guide rail. The telescopic beams extend along the guide rail to both ends of the guide rail or retract along the guide rail to the base.

[0019] Furthermore, the guide rail includes:

[0020] A limiting strip is attached to the inside of the first refrigerator door. The limiting strip has a groove along its length to restrict the horizontal movement of the drive assembly.

[0021] A rack is provided, which is spaced apart from and parallel to the limiting strip. The teeth of the rack are positioned opposite to the grooves of the limiting strip. The driving assembly is disposed between the limiting strip and the rack.

[0022] Furthermore, the driving component includes:

[0023] A gear, one side of which is engaged in the groove of the limiting strip, and the other side of which is engaged in the teeth of the rack;

[0024] An electric motor, wherein the rotor of the electric motor is fixed to the gear, and the end of the rotor passes through the gear;

[0025] A rubber block, which is rotatably connected to the rotor end of the gear;

[0026] The motor drives the gear and the rubber block to move along the guide rail. The rubber block presses down on the telescopic beam, compressing the telescopic beam from its extended state to its retracted state.

[0027] Compared with the prior art, the present invention sets the middle beam of the refrigerator as a telescopic middle beam. The telescopic middle beam is controlled by a controller to extend or retract. When the telescopic middle beam extends, it blocks the two refrigerator doors to prevent the loss of cold air inside the refrigerator. When the telescopic middle beam retracts, the relative movement between the sleeves of the telescopic middle beam causes friction, which can remove condensation on the telescopic middle beam. This solves the technical problem that the telescopic middle beam of the refrigerator cannot be used for condensation treatment in the prior art. Attached Figure Description

[0036] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0037] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0038] The central beam of a household refrigerator is mainly located between the doors. Currently, common refrigerators use a flip-up central beam to ensure the internal sealing of the refrigerator and thus maintain the cooling effect. However, because the central beam is located at the door gap, it is in direct contact with the cold air inside the refrigerator and the outside, making it very prone to condensation. Existing refrigerator central beams only keep the door gaps cold and do not treat condensation on the central beam itself. Therefore, this invention proposes a refrigerator with a guide rail on the inside of the first refrigerator door and a drive assembly that can move along the guide rail. A telescopic central beam is located on the first refrigerator door, between the two refrigerator doors. A controller drives the drive assembly on the guide rail to move within the guide rail, causing the telescopic central beam to extend and retract, thus removing condensation from the telescopic central beam. When the refrigerator door is opened, the drive assembly causes the telescopic central beam to retract, scraping away the condensation; when the refrigerator door is closed, the telescopic central beam extends and remains between the two refrigerator doors to ensure the internal sealing of the refrigerator.

[0039] like Figure 1-4 As shown, this invention proposes a refrigerator, including: a guide rail 6, a controller, a drive assembly, and a telescopic central beam. A telescopic central beam is provided on a first refrigerator door 1, located between the first and second refrigerator doors. The guide rail 6 is positioned along the length of the refrigerator door at the inner edge of the first refrigerator door 1. A drive assembly is provided on the guide rail 6, allowing movement along the guide rail 6 and compressing the telescopic central beam. The controller controls the extension or retraction of the telescopic central beam based on refrigerator door opening / closing signals and humidity signals inside the refrigerator. The telescopic central beam is used in double-door refrigerators; the door with the telescopic central beam installed is the first refrigerator door 1, and the door without it is the second refrigerator door. When the first refrigerator door 1 is opened, the controller drives the drive assembly to retract the telescopic central beam from its extended state. During the retraction process, condensation on the retracting device is removed. When the first refrigerator door 1 is closed, the controller controls the telescopic central beam to retract from its retracted state. The telescopic central beam is specifically positioned on one side opposite to the two doors of the refrigerator.

[0040] like Figure 1-4As shown, in a specific embodiment, a telescopic beam is used in a double-door refrigerator and is installed on the inside of one of the refrigerator doors. In this embodiment, the refrigerator door with the telescopic beam installed is the first refrigerator door 1, and the refrigerator door without the telescopic beam is the second refrigerator door. Specifically, a telescopic beam is provided on the inside of the first refrigerator door 1. When the telescopic beam extends, it blocks the gap between the first and second refrigerator doors. When it retracts, it scrapes against the condensation on the outside of the telescopic beam. A guide rail 6 is provided along the length of the refrigerator door at the inner edge of the first refrigerator door 1, forming a vertical guide rail 6 on the refrigerator door. A drive assembly that can move up and down along the guide rail 6 is provided on the guide rail 6. When the drive assembly moves on the guide rail 6, it presses against the telescopic beam, causing the telescopic beam to retract. The controller controls the telescopic beam to extend to block the gap between the two refrigerator doors or to retract to scrape against the condensation on the telescopic beam based on the refrigerator door opening / closing signal and the humidity signal inside the refrigerator.

[0041] like Figure 5-6 As shown, in a further embodiment, a telescopic beam is provided at the inner edge of the first refrigerator door 1. The telescopic beam includes: a plurality of sleeves 8, a spring 10 and a base 7.

[0042] Base 7 is fixed to the refrigerator door at the end of the guide rail 6;

[0043] Multiple sleeves 8 are tubular, with openings at the top and bottom. The sleeves 8 are sequentially arranged in ascending order of size, with the largest sleeve 8 fixed to the base 7 at the bottom. Each sleeve 8 has a first retaining ring on the inner side of its top and a second retaining ring on the outer side of its bottom. When the telescopic beam retracts, the extended sleeves 8 return to the largest sleeve 8. When extending, other sleeves 8 extend outwards from the largest sleeve 8, with the first and second retaining rings of adjacent sleeves 8 engaging. Specifically, the multiple sleeves 8 include a first sleeve 8, a second sleeve 8, and a third sleeve 8. The diameter of the first sleeve 8 is smaller than that of the second sleeve 8, and the second sleeve 8 is larger than that of the third sleeve 8. The sleeves 8 are arranged in ascending order of diameter, with the second sleeve 8 fitting outside the first sleeve 8 and the third sleeve 8 fitting outside the second sleeve 8. When the sleeves 8 extend, the first and second retaining rings of adjacent sleeves 8 engage. For example, the first retaining ring of the second sleeve 8 engages with the second retaining ring of the first sleeve 8, and the second retaining ring of the second sleeve 8 engages with the first retaining ring of the third sleeve 8. The first retaining ring of the innermost first sleeve 8 does not engage with the retaining rings of other sleeves 8, and the second retaining ring of the outermost third sleeve 8 does not engage with the retaining rings of other sleeves 8.

[0044] Spring 10 is disposed inside the smallest sleeve 8, with one end abutting against the base 7 and the other end abutting against the first retaining ring inside the smallest sleeve 8. The elastic force of spring 10 causes sleeve 8 to extend.

[0045] When the sleeve 8 extends, it extends in the opposite direction to the base 7; when the sleeve 8 retracts, it retracts in the direction of the base 7.

[0046] like Figure 1-4 As shown, in a further embodiment, the base 7 is provided with a door switch 11 for detecting the door opening and closing status and issuing opening and closing signals; when the controller receives the door opening signal, the controller controls the telescopic beam to retract and scrape the condensation on the telescopic beam; when the controller receives the door closing signal, the controller controls the telescopic beam to extend and block the gap between the two refrigerator doors to prevent the cold air in the refrigerator from flowing out from the gap between the two refrigerator doors and causing cold air loss.

[0047] When the drive assembly retracts the telescopic beam in its extended state, it presses down on the extended first sleeve 8, causing the first and second sleeves 8 to retract into the third sleeve 8. Then, the electromagnetic switch is de-energized, keeping the telescopic beam in its retracted state. When the drive assembly moves to its initial position, the electromagnetic switch is energized, causing the telescopic beam to extend via the spring 10, and the sleeves 8 to extend due to the elasticity of the internal spring 10. In another embodiment, after the telescopic beam has retracted, the drive unit does not need to move to its initial state. Instead, after the refrigerator door is closed, the electromagnetic switch is energized, and the drive assembly moves simultaneously with the unblocked telescopic beam.

[0048] Furthermore, without the need for an electromagnetic switch, the drive assembly is connected to the top of the smallest sleeve 8 of the telescopic beam, and the telescopic beam moves on the guide rail 6, causing the telescopic beam to extend or retract.

[0049] like Figure 5As shown, in a further embodiment, a humidity sensor is installed inside the refrigerator to detect the humidity inside. The controller records the number of times the door switch 11 sends an opening and closing signal, thus determining the number of times the telescopic beam retracts. When the number of times the refrigerator door opens and closes within a preset time period is less than a preset number (i.e., the number of times the telescopic beam retracts is less than a preset number), and the humidity sensor detects a humidity level greater than a preset humidity level, the controller drives the drive assembly to retract the telescopic beam, scraping against the condensation on the telescopic beam. Then, the electromagnetic switch is de-energized, causing the latch to lock the sleeve 8 in the retracted state, keeping it in the retracted state. The drive assembly moves back to the end of the guide rail 6, the electromagnetic switch is energized, the latch opens, and the telescopic beam extends again to block the gap between the two refrigerator doors, preventing cold air loss. Specifically, the preset number of times the refrigerator door opens and closes can be set to 4 times. The preset number of times the telescopic beam retracts is also 4 times. If the preset time for using the telescopic beam during the use of the refrigerator is one day, and the number of times the refrigerator door is opened and closed is less than 4, meaning the number of times the telescopic beam is triggered to extend and retract is less than 4, then the telescopic beam will extend and retract according to the humidity inside the refrigerator to prevent condensation from remaining on the telescopic beam even after the number of extensions and retractions is insufficient. If the humidity inside the refrigerator is greater than the preset humidity, the controller controls the drive component to retract the telescopic beam to scrape away the condensation. Then, the electromagnetic switch is de-energized, causing the latch to lock the sleeve 8 in the retracted state, keeping it in the retracted state. The drive component moves back to the end of the guide rail 6, the electromagnetic switch is energized, the latch is opened, and the telescopic beam extends again to block the gap between the two refrigerator doors, preventing cold air loss.

[0050] Specifically, the base has a grooved locking strip, and the bottom of the sleeve has a locking block. When the telescopic beam is in the retracted state, the locking block at the bottom of the sleeve inserts into the groove of the locking strip in the base. When the electromagnetic switch is not energized, the locking strip locks the locking block, keeping the telescopic beam in the retracted state. When the electromagnetic switch is energized, it moves the locking strip, causing the locking block to disengage from the locking strip, and the spring force causes the telescopic beam to pop out.

[0051] like Figure 5-6 As shown, in a further embodiment, the telescopic beam also includes a pad 9 disposed at the top of the smallest sleeve, that is, disposed at the top of the first sleeve 8. The pad 9 prevents the spring 10 disposed in the first sleeve 8 from running out. At the same time, when the drive assembly drives the telescopic beam to extend or retract, the drive assembly can press down the pad 9 and drive the telescopic beam to move.

[0052] In a further embodiment, two sets of drive components and telescopic beams are provided respectively. The initial positions of the two sets of drive components are respectively set at the upper and lower ends of the guide rail 6. The bases 7 of the two sets of telescopic beams are set back to back in the middle of the guide rail 6. The telescopic beams extend along the direction of the guide rail 6 to both ends of the guide rail 6 or retract along the guide rail 6 to the base 7. After the two sets of telescopic beams are extended, the total length of the two sets of components is the same as the height of the refrigerator door.

[0053] When only one set of telescopic beams is provided, the base 7 is set at the bottom or top of the inner edge of the refrigerator door. After the sleeve 8 of the telescopic beam is extended, its overall length is the same as the height of the refrigerator door, which can block the gap between the two refrigerator doors.

[0054] In a further embodiment, the guide rail 6 includes: a limiting strip, which is attached to the inner side of the first refrigerator door 1, and has a groove in its extension direction to restrict the horizontal movement of the drive assembly; a rack, which is spaced apart from and parallel to the limiting strip, with the teeth of the rack facing the groove of the limiting strip, and the gear of the drive assembly is disposed between the limiting strip and the rack. The base 7 of the telescopic beam is fixed to the refrigerator, and the base 7 also fixes the limiting strip and the rack.

[0055] In a further embodiment, the drive assembly includes: a gear 4, a motor 2, and a rubber block 5.

[0056] Gear 4, one side of gear 4 is engaged in the groove of the limiting strip, and the other side is engaged in the teeth of the rack;

[0057] Motor 2, the rotor of motor 2 is fixed to gear 4, and the end of the rotor passes through gear 4;

[0058] Rubber block 5 is rotatably connected to the rotor end of motor 2, and the rubber block 5 presses the end of the sleeve 8 of the telescopic beam.

[0059] When the motor 2 is running, the rotor rotates, causing the gear 4 to move along the guide rail 6. Since the motor 2, gear 4 and rubber block 5 are integrated, the rubber block 5 also moves up and down with the gear 4. The rubber block 5 presses down on the pad 9, compressing the sleeve 8, which is in an extended state, to a retracted state.

[0060] The refrigerator proposed in this invention is a double-door refrigerator. A telescopic beam is installed on the inner edge of one of the refrigerator doors, so that the telescopic beam can block the two refrigerator doors and prevent cold air loss.

[0061] Compared with the prior art, the present invention sets the middle beam of the refrigerator as a telescopic middle beam. The controller controls the drive device to extend or retract the telescopic middle beam. When the telescopic middle beam extends, it blocks between the two refrigerator doors to prevent the loss of cold air inside the refrigerator. When the telescopic middle beam retracts, the relative movement between the sleeves 8 of the telescopic middle beam causes friction, which can remove condensation on the telescopic middle beam. This solves the technical problem that the moving middle beam of the refrigerator in the prior art cannot be used for condensation treatment.
