Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerator manufacturing, in particular to a refrigerator. BACKGROUND

[0002] With the improvement of people's living standards, the demand for refrigerators is also increasing, and automatic door opening refrigerators gradually occupy the market. The existing automatic door opening refrigerator generally installs a pressing assembly including a pressure sensor and a trigger in an integrated structure in the box body. When the user presses the box door, the box door extrudes the trigger on the side of the box body, so that the trigger triggers the pressure sensor, thereby controlling the opening of the box door to realize automatic door opening.

[0003] But this structure needs to be set in the side hole of the box body, so that part of the trigger can be inserted into the hole and protrude from the box body. In this way, the box door can be smoothly pressed against the trigger on the side of the box body. The position of the hole on the side of the box body makes the trigger and the hole located in the user's line of sight after the box door is opened, resulting in poor user experience. And the pressure sensor and trigger in the pressing assembly are set in one body, which needs to be disassembled and checked one by one during maintenance, which is time-consuming and laborious. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a refrigerator that can improve user experience and facilitate maintenance.

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

[0006] A refrigerator includes a box body, a box door, and a pressing assembly. The box door is installed on the box body, and the pressing assembly is used to detect pressure to control the opening of the box door. The pressing assembly includes:

[0007] A pressure sensor is installed on the side of the box body facing the box door.

[0008] A housing is installed on the box door.

[0009] A trigger unit has one end installed on the housing and the other end extending out of the housing and penetrating to the side of the box door facing the box body.

[0010] The trigger unit can extrude the pressure sensor in response to the pressing of the box door and trigger the pressure sensor to control the opening of the box door.

[0011] It can be understood that the application sets the pressing assembly, and installs the trigger unit in the pressing assembly on the side of the box door facing the box body, so that the opening position on the refrigerator is moved out of the user's visual range, thereby improving the user's use experience. Meanwhile, by installing the pressure sensor on the side of the box body, the trigger unit and the pressure sensor are respectively installed at different positions, so that when any one of the two components needs to be repaired and maintained, only the corresponding component needs to be disassembled, thereby reducing the overall disassembly and one-by-one checking process, facilitating repair and maintenance, and saving time and effort.

[0012] In one of the embodiments, a cover plate is arranged on the side of the box body facing the box door, and the pressure sensor is arranged on the side of the cover plate away from the box door.

[0013] The trigger unit extrudes the cover plate to trigger the pressure sensor.

[0014] It can be understood that the cover plate not only can separately fix the pressure sensor on the side of the box body to achieve the installation of the pressure sensor, but also can protect the pressure sensor, so that the trigger unit triggers the pressure sensor by extruding the cover plate, thereby avoiding the damage of the pressure sensor caused by the direct extrusion and contact of the trigger unit.

[0015] In one of the embodiments, the pressure sensor is installed on the cover plate by a clamping method, and / or an adhesive is arranged between the pressure sensor and the cover plate.

[0016] In one of the embodiments, a sink is arranged on the side of the cover plate facing the box door, and the sink is used for the end of the trigger unit away from the shell to extend into.

[0017] It can be understood that the thickness of the sink position on the cover plate is thinner, and when the trigger unit extrudes the cover plate, the position on the cover plate is more easily deformed and triggers the pressure sensor, so that the structure of the pressure sensor is protected, and the sensitivity of the refrigerator when pressing the door is improved.

[0018] In one of the embodiments, the trigger unit includes a trigger rod and an elastic member, a through hole is arranged on the shell, one end of the trigger rod is located in the shell, the other end of the trigger rod extends out through the through hole and penetrates the side of the box door facing the box body, and the trigger rod can be extruded and perform extension and contraction relative to the through hole.

[0019] The elastic member is arranged in the shell, and one end of the elastic member is limited in the shell, and the other end of the elastic member is limited in the trigger rod.

[0020] It can be understood that the elastic member can cooperate with the trigger rod to perform extension and contraction in the through hole, so that the trigger unit is extruded and moves to trigger the pressure sensor, thereby realizing the function of pressing the door of the refrigerator.

[0021] In one of the embodiments, the triggering unit further comprises a guiding structure arranged in the housing for guiding the movement of the triggering rod.

[0022] It can be understood that the guiding structure can guide the triggering rod to move stably in the same direction, so as to ensure that the triggering rod can accurately trigger the pressure sensor.

[0023] In one of the embodiments, the guiding structure comprises a guiding rod, and a guiding hole is arranged on one end of the triggering rod in the housing, one end of the guiding rod is limited on the housing, and the other end extends into the guiding hole.

[0024] The elastic member is sleeved on the guiding rod, and one end of the elastic member abuts against the guiding rod, and the other end abuts against the hole wall of the guiding hole.

[0025] It can be understood that the arrangement of the guiding rod can ensure the expansion and contraction of the elastic member, so that the function of the refrigerator to press the door open is stably realized.

[0026] In one of the embodiments, the guiding structure comprises a guiding strip, a guiding groove is arranged on the inner wall of the housing, the guiding groove extends along the axis of the through hole, the guiding strip is arranged on the outer wall of the triggering rod, and the guiding strip and the guiding groove are in sliding fit.

[0027] It can be understood that the guiding strip and the guiding groove are in sliding fit, so that the triggering rod will not be stuck when it expands and contracts.

[0028] In one of the embodiments, the number of the guiding strips is two, and the number of the guiding grooves is two, and each guiding strip corresponds to one guiding groove.

[0029] It can be understood that the arrangement of two guiding strips can not only better limit the triggering rod, but also make the movement of the triggering rod more stable and the movement direction more accurate.

[0030] In one of the embodiments, a limiting ring is arranged on one side of the housing facing the box, and the limiting ring protrudes from one side of the box along the axis direction of the through hole.

[0031] It can be understood that when the box door is pressed, the limiting ring can abut against the cover plate on the box before the housing, so as to avoid that the housing directly impacts the cover plate due to too large pressure on the box door, and the pressure sensor on the inner side of the cover plate is damaged.

[0032] Compared with the prior art, the refrigerator improves the user experience by setting the pressing assembly, installing the trigger unit in the pressing assembly on the side of the cabinet door facing the cabinet, and moving the opening position on the refrigerator out of the user's visual range; meanwhile, by installing the pressure sensor on the cabinet side, the trigger unit and the pressure sensor are installed at different positions, so when any of the two components needs to be repaired and maintained, only the corresponding component needs to be disassembled, which reduces the overall disassembly and one-by-one troubleshooting process, facilitates repair and maintenance, and saves time and effort.

[0047] As Figures 1 to 6As shown, the refrigerator 200 provided by the present application comprises a cabinet 201, a cabinet door 202 and a pressing assembly 100, the cabinet door 202 is installed on the cabinet 201, and the pressing assembly 100 is used for detecting pressure to control the cabinet door 202 to open; the pressing assembly 100 comprises a pressure sensor 10, a shell 20 and a trigger unit 30, the pressure sensor 10 is installed on the side of the cabinet 201 facing the cabinet door 202; the shell 20 is installed on the cabinet door 202; one end of the trigger unit 30 is installed on the shell 20, and the other end of the trigger unit 30 extends out of the shell 20 and penetrates to the side of the cabinet door 202 facing the cabinet 201; wherein, the trigger unit 30 can extrude the pressure sensor 10 in response to the pressing of the cabinet door 202, and make the pressure sensor 10 trigger, so as to control the cabinet door 202 to open, that is, open the cabinet 201. It can be understood that the trigger unit 30 is installed on the side of the cabinet door 202 facing the cabinet 201, so that the opening position is back to the user's visual angle, avoiding bringing too much visual impact to the user, thereby improving the user's experience; at the same time, the installation positions of the pressure sensor 10 and the trigger unit 30 are separated, that is, the pressure sensor 10 is installed in the shell 20 on the side of the cabinet 201, and the trigger unit 30 is installed on the cabinet door 202, which is set, when one of the pressure sensor 10 or the trigger unit 30 needs to be maintained, the entire pressing assembly 100 does not need to be disassembled and each component in the pressing assembly 100 needs to be checked one by one, only the corresponding component needs to be disassembled, which is more time-saving and labor-saving.

[0048] Here, the refrigerator 200 is a pressing door opening refrigerator, that is, the user can trigger the pressure sensor 10 by pressing the cabinet door 202, and the pressure sensor 10 controls the driving part to drive the cabinet door 202 to open after receiving the signal. Here, the structure of the driving part driving the cabinet door 202 to open is not the focus of the present application, and will not be described here.

[0049] As shown in Figure 1 and Figure 2 , the side of the cabinet 201 facing the cabinet door 202 is provided with a cover plate 11, and the pressure sensor 10 is installed on the side of the cover plate 11 away from the cabinet door 202; the trigger unit 30 extrudes the cover plate 11 to trigger the pressure sensor 10. In this way, not only can the pressure sensor 10 be installed separately on the cabinet 201 through the cover plate 11, but also the trigger unit 30 can trigger the pressure sensor 10 by extruding the cover plate 11, avoiding damage after long-term direct extrusion of the pressure sensor 10 or after impact.

[0050] Specifically, the pressure sensor 10 can be installed on the cover plate 11 by clamping, and can also be connected with the cover plate 11 by other installation methods such as bolts and embedded type, and the specific installation and connection method of the pressure sensor 10 and the cover plate 11 can be determined according to the actual situation. In this embodiment, the pressure sensor 10 is installed on the cover plate 11 in a clamping manner by setting a clamping structure 12 on the cover plate 11.

[0051] Preferably, the clamping structures 12 are arranged in a plurality, and the plurality of clamping structures 12 are arranged circumferentially around the cover plate 11 to position and fix the pressure sensor 10 at circumferential positions, thereby improving the installation stability. Here, the number of clamping structures 12 is arranged to be 6-8, for example, six, seven, or eight, etc. Of course, it is not limited thereto, and the number of clamping structures 12 can also be arranged according to actual needs.

[0052] Further, the pressure sensor 10 and the cover plate 11 can also be provided with adhesive 13 to further increase the stability of the connection between the pressure sensor 10 and the cover plate 11. Here, the adhesive 13 can be glue, double-sided tape, etc.

[0053] In an embodiment, the side of the cover plate 11 facing the cabinet door 202 is provided with a recess 112 for the end of the trigger unit 30 away from the housing 20 to extend into. It can be understood that the thickness of the cover plate 11 at the position of the recess 112 is thinner than the thickness of the cover plate 11 at other positions, and when the trigger unit 30 presses the cover plate 11, the cover plate 11 at this position is more easily deformed and triggers the pressure sensor 10, thereby protecting the structure of the pressure sensor 10 and improving the sensitivity of the refrigerator 200 when the cabinet door 202 is pressed to open. At the same time, the recess 112 can also be used as a guide groove to guide the trigger unit 30 to extend in, thereby improving the stability of triggering.

[0054] As shown in Figure 3 and Figure 4 , the housing 20 is provided with a through hole 21 to enable the trigger unit 30 to extend out of the housing 20 and press the pressure sensor 10.

[0055] In an embodiment, the inner wall of the housing 20 is provided with a guide groove 22 extending along the axis of the through hole 21 to enable the trigger unit 30 to extend and retract relative to the through hole 21 along the extension direction of the guide groove 22.

[0056] As a preferred, the housing 20 is provided with a limiting ring 23 on the side facing the cabinet 201, and the limiting ring 23 protrudes from the side of the cabinet 201 along the axis direction of the through hole 21. In this way, when the cabinet door 202 is pressed, the limiting ring 23 can abut the cover plate 11 on the cabinet 201 before the housing 20, thereby avoiding the housing 20 directly impacting the cover plate 11 due to excessive pressure on the cabinet door 202, which can damage the pressure sensor 10 inside the cover plate 11.

[0057] As shown in Figure 3 and Figure 5As shown, the trigger unit 30 comprises a trigger rod 31 and an elastic member 32, one end of the trigger rod 31 is located in the shell 20, the other end extends out through the through hole 21 and is arranged on the side of the cabinet 201 through the door 202, and the trigger rod 31 can be correspondingly extruded to make telescopic movement relative to the through hole 21; the elastic member 32 is arranged in the shell 20, and one end of the elastic member 32 is limited in the shell 20, and the other end is limited in the trigger rod 31. In this way, the elastic member 32 can cooperate with the trigger rod 31 to make telescopic movement in the through hole 21, so that the trigger unit 30 is extruded and moved to trigger the pressure sensor 10, thereby realizing the pressing door opening function of the refrigerator 200.

[0058] Please continue to refer to Figures 3 to 5 , the trigger unit 30 further comprises a guide structure 33, the guide structure 33 is arranged in the shell 20 and is used for guiding the movement of the trigger rod 31. In this way, the guide structure 33 can guide the trigger rod 31 to stably move in the same direction, so as to ensure that the trigger rod 31 can accurately trigger the pressure sensor 10.

[0059] Further, the guide structure 33 comprises a guide rod 331, a guide hole 332 is formed on one end of the trigger rod 31 located in the shell 20, one end of the guide rod 331 is limited on the shell 20, and the other end extends into the guide hole 332; the elastic member 32 is sleeved on the guide rod 331, and one end of the elastic member 32 abuts against the guide rod 331, and the other end abuts against the hole wall of the guide hole 332. It can be understood that the arrangement of the guide rod 331 can ensure the telescopic movement of the elastic member 32, so as to stably realize the pressing door opening function of the refrigerator 200.

[0060] In an embodiment, the guide structure 33 comprises a guide strip 333, the guide strip 333 is arranged on the outer wall of the trigger rod 31 and is in sliding cooperation with the guide groove 22. In this way, the guide strip 333 and the guide groove 22 can be in sliding cooperation, so that the trigger rod 31 will not be stuck when making telescopic movement.

[0061] As preferred, the number of guide strips 333 is two, the number of guide grooves 22 is two, and each guide strip 333 corresponds to one guide groove 22. In this way, the trigger rod 31 can be limited from multiple positions, so that the movement is more stable, and the accuracy of the movement direction is improved.

[0062] Here, the number of guide strips 333 is not limited to two, and can be one or more, each guide strip 333 corresponds to one guide groove 22, and the specific number of guide strips 333 can be determined according to actual conditions, and the position of the guide strip 333 is not limited, which can be any position on the outer wall of the trigger rod 31, and the specific position of the guide strip 333 can also be determined according to actual conditions.

[0063] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0064] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent application scope. It should be pointed out that for ordinary skilled persons in the art, some changes 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.
