Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, in particular to an automatic door opening refrigerator. BACKGROUND

[0002] In the development of refrigerator technology, the door opening method of the refrigerator has also been improved from the traditional manual opening to the electric opening, which is convenient for situations where manual opening is not convenient, and also enables people with physical discomfort to use automatic door opening refrigerators.

[0003] Most of the current electric door opening devices are electric push rod assemblies, and the push rod assembly is usually installed at the bottom or top of the automatic door opening refrigerator. After the pressing sensor receives the pressing force signal, the push rod is used to push the door open by using the ejection force of the push rod. During this process, the freezing door is subjected to a certain torque, resulting in uneven stress and causing the problem of jamming. At the same time, when the electric push rod structure is installed at the bottom or top of the cabinet, during maintenance, due to the limited installation position of the push rod, it needs to be replaced after the refrigerator is tilted or tilted at a large angle, which is difficult to maintain. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide an automatic door opening refrigerator which is convenient to maintain.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0013] It can be understood that the pre-embedded box provides a mounting space and protection for the motor, avoids direct exposure of the motor to the internal environment of the automatic door opening refrigerator, reduces the erosion of the motor by water vapor, dust and the like, and prolongs the service life of the motor.

[0014] In one of the embodiments, the pre-embedded box is provided with a wire hole, the wire hole is in communication with the mounting groove, and a first sealing element is arranged in the wire hole.

[0015] In one of the embodiments, along the width direction of the box, a second sealing element is arranged between the pre-embedded box and the inner wall of the box.

[0016] It can be understood that the arrangement of the second sealing element enhances the sealing performance between the pre-embedded box and the box, effectively reduces the leakage of cold air in the automatic door opening refrigerator, helps to maintain the low temperature environment in the automatic door opening refrigerator, reduces energy consumption, and improves the refrigeration efficiency.

[0017] In one of the embodiments, the second sealing element is configured as a sponge rubber tape, and a sealant is filled between the sponge rubber tape and the pre-embedded box.

[0018] It can be understood that the combination of the sponge rubber tape and the sealant greatly improves the sealing effect, enhances the temperature maintaining capacity of the interior of the automatic door opening refrigerator, and also plays a certain role in shock absorption and noise reduction.

[0019] In one of the embodiments, along the length direction of the box, a heat insulation plate is arranged between the pre-embedded box and the inner wall of the box.

[0020] It can be understood that the arrangement of the heat insulation plate can effectively ensure the heat preservation effect of the position.

[0024] It can be understood that the sensor is arranged to make the automatic door opening more intelligent and sensitive, and can accurately control the motor operation according to the user's needs, realizing more accurate and convenient door opening operation.

[0025] In one of the embodiments, the number of the first side surfaces is configured to be two along the length direction of the box body, and the push rod mechanism is installed on each of the first side surfaces.

[0026] It can be understood that the push rod mechanism is installed on both of the first side surfaces of the box body, which provides more balanced pushing force, makes the door opening more stable, and also increases the reliability of the automatic door opening system.

[0027] Compared with the prior art, the automatic door opening refrigerator sets the push rod mechanism at the first side surface sliding rail, that is, the push rod mechanism is arranged close to the sliding rail. In this way, the force point of the push rod mechanism pushing the door body is close to the sliding rail movement position, thereby reducing the action distance between the sliding rail and the push rod mechanism, greatly reducing the door opening torque, and ensuring the smooth force in the door opening process. At the same time, the push rod mechanism is arranged on the first side surface, so that the automatic door opening refrigerator does not need to be tilted at a large angle for maintenance, and the maintenance is more convenient.

As used in the description of the application, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0041] Referring to Figures 1 to 5 The present application provides an automatic door opening refrigerator 100, which can effectively reduce the opening torque and ensure smooth force during the opening process, so that the door opening is more smooth.

[0042] Specifically, the automatic door opening refrigerator 100 includes a cabinet 10, a slide rail 20, a door body 30, and a push rod mechanism 40. The cabinet 10 has a first side surface 11 and a second side surface 12. The first side surface 11 is located in the length direction x of the cabinet 10, and the second side surface 12 is located in the width direction y of the cabinet 10, that is, the depth direction of the cabinet 10. The slide rail 20 is arranged in the cabinet 10 along the width direction y of the cabinet 10. The door body 30 is installed on the second side surface 12 of the cabinet 10 and is in sliding connection with the slide rail 20. The push rod mechanism 40 is installed on the first side surface 11 and located at the slide rail 20, and the push rod mechanism 40 can move along the width direction y of the cabinet 10 to push the door body 30 and open the door. In this way, by arranging the push rod mechanism 40 at the slide rail 20 of the first side surface 11, that is, the push rod mechanism 40 is arranged close to the slide rail 20. In this way, the force point of the push rod mechanism 40 pushing the door body 30 is close to the movement position of the slide rail 20, thereby reducing the action distance between the slide rail 20 and the push rod mechanism 40, greatly reducing the opening torque and ensuring smooth force during the opening process. At the same time, the push rod mechanism 40 is arranged on the first side surface 11, so that when maintaining, the automatic door opening refrigerator 100 no longer needs to be inclined at a large angle, and the maintenance is more convenient.

[0043] In an embodiment, along the length direction x of the cabinet 10, the number of the first side surface 11 is configured to be two, and each first side surface 11 is installed with a push rod mechanism 40. The two push rod mechanisms 40 jointly push out to provide more balanced pushing force, so that the door body 30 is opened more stably, and the reliability of automatic door opening is also increased.

[0044] As Figure 2 and Figure 3As shown, the push rod mechanism 40 includes a pre-embedded box 41, a motor 42, and a push rod 43; the first side surface 11 is provided with a mounting groove 121 at a position close to the slide rail 20, the pre-embedded box 41 is mounted in the mounting groove 121, the motor 42 is mounted in the pre-embedded box 41, one end of the push rod 43 is connected with the motor 42, and the other end extends along the width direction y of the box body 10 and can pass through the second side surface 12 to push the door body 30 and open. In this way, the pre-embedded box 41 is provided to provide a mounting space and protection for the motor 42, avoiding direct exposure of the motor 42 to the internal environment of the automatic door opening refrigerator 100, reducing the corrosion of the motor 42 by water vapor, dust, etc., and prolonging the service life of the motor 42.

[0045] As shown in Figure 1 The box body 10 is filled with foaming material, and the pre-embedded box 41 is fixed to the box body 10 through the foaming material. In this way, the installation stability of the pre-embedded box 41 is enhanced, and the foaming material also has a certain heat preservation and sealing effect, which helps to improve the overall performance of the automatic door opening refrigerator 100. Moreover, when the box body 10 is filled with foaming material, the pre-embedded box 41 can be fixed, and no additional components are needed to fix the pre-embedded box 41, so the assembly is more convenient.

[0046] In an embodiment, a wire hole 411 is formed on the pre-embedded box 41, the wire hole 411 is in communication with the mounting groove 121, and a first sealing member 412 is arranged in the wire hole 411. The wire hole 411 is used to pass through the electric wire to supply power or signal to the motor 42. The first sealing member 412 can seal the wire hole 411, thereby preventing the foaming material from entering the pre-embedded box 41 during foaming. Here, the first sealing member 412 can be a rubber sleeve, a silica gel sleeve, etc.

[0047] Along the width direction y of the box body 10, a second sealing member 413 is arranged between the pre-embedded box 41 and the inner wall of the box body 10. The arrangement of the second sealing member 413 further enhances the sealing performance between the pre-embedded box 41 and the box body 10, effectively reduces the leakage of cold air inside the automatic door opening refrigerator 100, helps to maintain the low-temperature environment inside the automatic door opening refrigerator 100, reduces energy consumption, and improves the refrigeration efficiency.

[0048] As a preferred, the second sealing member 413 is configured as a sponge rubber tape, and a sealant is filled between the sponge rubber tape and the pre-embedded box 41. The combination of the sponge rubber tape and the sealant greatly improves the sealing effect, enhances the ability to maintain the temperature inside the automatic door opening refrigerator 100, and also has a certain shock absorption and noise reduction effect.

[0049] As shown in Figure 4 and Figure 5As shown, in an embodiment, along the length direction x of the cabinet 10, a heat insulation plate 414 is arranged between the embedded box 41 and the inner wall of the cabinet 10. It can be understood that, because the embedded box 41 is arranged at this position of the cabinet 10, the embedded box 41 will occupy the original foamed material at this position. The heat insulation plate 414 has good heat insulation performance, and the thermal conductivity of the heat insulation plate 414 is about one tenth of that of the foamed material, so that the heat insulation plate 414 can well insulate heat and avoid the loss of cold air inside the automatic door opening refrigerator 100.

[0050] Here, the heat insulation plate 414 can be selected from a vacuum heat insulation plate, polyurethane foam and the like.

[0051] Preferably, the thickness of the heat insulation plate 414 is greater than or equal to 10 mm, so as to ensure sufficient heat insulation performance, effectively block the external heat from entering the inside of the automatic door opening refrigerator 100, and maintain the stable low temperature of the automatic door opening refrigerator 100. Here, the thickness of the heat insulation plate 414 can be set to 10 mm, 11 mm, 12 mm, 13 mm, etc.

[0052] In an embodiment, the motor 42 can be a stepper motor or a servo motor, etc.

[0053] In the present embodiment, the motor 42 is configured as a stepper motor, and a position sensor 421 is installed on the stepper motor for controlling the pushing distance of the push rod 43.

[0054] Preferably, the position sensor 421 is an encoder. When the door needs to be opened, the motor 42 receives an external signal to drive the push rod 43 to push out, and the encoder detects that the motor 42 drives the push rod 43 to push out to an appropriate distance, and can ensure that the push rod 43 moves the door body 30 by the same distance each time through the encoder, preventing the user experience from being affected due to different pushing distances of the push rod 43 to push out the automatic door opening refrigerator 100.

[0055] In an embodiment, the automatic door opening refrigerator 100 further comprises a sensor 44, which is installed in the embedded box 41 and electrically connected between the motor 42, and the sensing part 441 of the sensor 44 is located on the second side surface 12.

[0056] In the present embodiment, the sensor 44 is a pressure sensor, when the user presses the door body 30, the sensor 44 receives the pressing signal and gives a door pushing signal, so as to use the ejecting force of the push rod 43 to overcome the self-locking force of the door slide rail 20 to push the door body 30 to a certain distance.

[0057] The technical features of the above-described embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0058] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that, for those of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
