Refrigerator

Abstract

When the refrigerator is used and a drawer needs to be opened, the drawer is pressed to move from a locking position to an unlocking position, a first locking assembly and a second locking assembly are correspondingly switched to an unlocking state, and in other words, the second locking assembly unlocks the first locking assembly. Due to the fact that the force storage assembly also moves from the locked state to the unlocked state, the force storage assembly can move the drawer out of the refrigeration chamber through the elastic force of the force storage assembly. Therefore, under the mutual coordination effect of the first locking assembly, the second locking assembly and the force storage assembly, the drawer can be stably and reliably closed, the drawer can be automatically ejected outwards through pressing operation when needing to be opened, driving of power mechanisms such as a motor is not needed, the overall structure is relatively simple, cost is low, maintainability is high, and the drawer can be conveniently and rapidly opened. And the problem that an electric-driven automatic drawer is high in cost and only suitable for part of high-end refrigerators is solved.

TECHNICAL FIELD

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

[0002] As one of important household appliances, the refrigerator is more and more popular in people's life. There are many opening modes of the refrigerator, which can be configured with a rotatable opening and closing door body, a drawer, or a combination of the rotatable opening and closing door body and the drawer. For the refrigerator configured with the drawer, if food is taken out of the drawer or put into the inside of the drawer, the opening and closing of the drawer is usually realized by manually pushing and pulling the drawer.

[0003] However, since the user needs to manually push and pull the drawer, it is inconvenient to use the drawer when the user has food in hand or is not convenient to push and pull the drawer. In addition, when the user pulls the drawer with oil stains on hand, the oil stains on hand are easy to stick to the drawer handle.

[0004] In the related art, an electrically driven automatic drawer is proposed, which is generally driven by a motor, and a gear, a rack or a screw is used for transmission to realize automatic opening or closing of the drawer. Although the transmission is stable, the motor and the related transmission device have high cost, and in order to cooperate with the automatic drawer, an additional drawer slide needs to be matched, and the overall structure is complex.

And since the force storage assembly is also moved from the locked state to the unlocking state, the force storage assembly moves the drawer out of the refrigeration compartment.

[0040] Conversely, when the drawer needs to be closed, the drawer is pushed into the refrigeration compartment, so that the drawer moves to the locking position, and the first locking assembly and the second locking assembly are locked and matched with each other, and the second locking assembly plays a limiting role on the first locking assembly, which can prevent the drawer from being pulled out of the refrigeration compartment. In addition, the drawer is pressed by the force storage assembly, so that the force storage assembly is switched to the force storage state. In addition, the force storage assembly is locked when it is in the force storage state, so as to prevent the drawer from being mistakenly pushed out.

[0041] Therefore, under the mutual coordination of the first locking assembly, the second locking assembly and the force storage assembly, stable and reliable closing of the drawer can be realized, and the drawer can be automatically popped out outward by pressing operation when the drawer needs to be opened, without the need of a motor or other power mechanism for driving, so that the overall structure is relatively simple, the cost is low and the maintainability is high, and the refrigerator can be applied to middle and low-end refrigerators, thereby solving the problem that the electrically-driven automatic drawer is high in cost and only applicable to some high-end refrigerators.

DETAILED DESCRIPTION

[0058] In order to make the above objectives, features and advantages of the present application more apparent, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to fully understand the present application. However, the present application can be implemented in many other different ways than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0059] It should be noted that, for the convenience of description and understanding, in the embodiments, "front", "back", "upper", "lower", "left" and "right" are taken as the state of the refrigerator standing, the direction of the refrigerator facing the user is the front, and the direction of the refrigerator facing away from the user is the back, and the vertical direction is the upper and lower direction.

[0060] Figure 1 A structural schematic diagram of the refrigerator 10 of an embodiment of the present application is shown.

[0061] Reference Figure 1 , the present embodiment provides a refrigerator 10 for storing items at low temperature, which can also be a refrigerated display cabinet or a refrigerated wine cabinet. The refrigerator 10 comprises a cabinet 11. The cabinet 11 is provided with a refrigeration compartment 111. The refrigeration compartment 111 is used to store food and other items.

[0062] The cabinet 11 comprises an inner container, an outer shell and a heat insulation layer. The inner container is used to form the refrigeration compartment 111. The outer shell can be connected to the outer side of the inner container to form the appearance of the refrigerator 10. The heat insulation layer can be filled between the inner container and the outer shell to block the heat transfer between the refrigeration compartment 111 and the space outside the cabinet 11. Optionally, the heat insulation layer comprises but is not limited to various heat preservation materials such as polyurethane or thermal insulation cotton.

[0063] In some embodiments, the number of refrigeration compartments 111 is not limited to one, and can be, for example, multiple. The multiple refrigeration compartments 111 comprise a refrigeration compartment and a freezing compartment. The refrigerator 10 further comprises a refrigeration system and an air duct assembly 12, which is shown as Figure 10 The refrigeration system and the air duct assembly 12 are both arranged inside the cabinet 11, and the specific structure and arrangement position can refer to the refrigeration system and the air duct assembly 12 in the related art, which will not be described here.

[0064] For example, the air duct assembly 12 is arranged inside the refrigeration compartment 111, and the air duct assembly 12 is arranged in a spaced manner with the rear wall of the refrigeration compartment 111 and cooperates to form an air duct.

[0065] The refrigeration system transfers cold energy to the air in the air duct assembly 12, so that cold air can be obtained in the air duct assembly 12. The air duct assembly 12 can be selectively penetrated with the refrigeration compartment 111, so as to guide the air in the air duct assembly 12 into the refrigeration compartment 111, so as to refrigerate the refrigeration compartment 111 to obtain a refrigeration environment.

[0066] For example, referring to Figure 2 , Figure 2A structure schematic diagram of a refrigeration system in the refrigerator 10 is provided for the embodiments of the present disclosure, and the refrigeration system is used to provide cold energy for the refrigeration compartment 111. Optionally, the refrigeration system comprises a compressor 101, an evaporator 102, a drying filter (not shown in the figure), a capillary tube 103, a condenser 104, and a gas-liquid separator (not shown in the figure). The working process of the refrigeration system comprises a compression process, a condensation process, a throttling process, and an evaporation process. In the compression process, the power cord of the refrigerator 10 is plugged in, and the compressor 101 starts to work when the contact of the temperature controller is connected. The low-temperature and low-pressure refrigerant is sucked into the compressor 101, compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 101, and then discharged into the condenser 104. In the condensation process, the high-temperature and high-pressure refrigerant gas is cooled by the condenser 104, and the temperature continuously decreases. The refrigerant is gradually cooled into saturated vapor at room temperature and high pressure, and further cooled into saturated liquid. The temperature no longer decreases, and the temperature at this time is called the condensation temperature. The pressure of the refrigerant in the entire condensation process is almost unchanged. In the throttling process, the saturated liquid refrigerant after condensation flows into the capillary tube 103 after filtering out water and impurities by the drying filter, and is throttled and depressurized by the capillary tube 103. The refrigerant becomes wet steam at room temperature and low pressure. In the evaporation process, the wet steam at room temperature and low pressure starts to absorb heat in the evaporator 102 to vaporize. Not only the temperature of the evaporator 102 and its surrounding environment is reduced, but also the refrigerant is changed into low-temperature and low-pressure gas. The refrigerant discharged from the evaporator 102 is returned to the compressor 101 again after passing through the gas-liquid separator, and the above process is repeated. The heat in the refrigeration compartment 111 of the refrigerator 10 is transferred to the air outside the cabinet 11, and the purpose of refrigeration is achieved.

[0067] The air duct assembly 12 can respectively deliver cold energy to the refrigeration compartment and the freezer compartment, so that the air in the air duct assembly 12 can respectively transmit cold energy to the refrigeration compartment and the freezer compartment, to maintain the refrigeration environment in the refrigeration compartment and the freezer compartment.

[0068] The internal temperature of the refrigeration compartment is maintained at, for example, between 0℃ and 5℃, to store items in a refrigeration mode. The internal temperature of the freezer compartment is maintained at, for example, between -30℃ and 0℃, to store items in a freezing mode. In addition, the plurality of refrigeration compartments 111 can also comprise other chambers, such as a vacuum chamber, a variable-temperature chamber, etc., which will not be described herein.

[0069] The refrigeration compartment and the freezer compartment can be arranged along the width direction of the refrigerator 10, or arranged along the height direction of the refrigerator 10, or arranged in other manners, which will not be limited herein. When the refrigeration compartment and the freezer compartment are arranged along the width direction of the refrigerator 10, for example, the refrigeration compartment can be located on the right side of the freezer compartment. When the refrigeration compartment and the freezer compartment are arranged along the height direction of the refrigerator 10, for example, the refrigeration compartment can be located above the freezer compartment.

[0070] The refrigerator 10 can further include a door body (not shown) rotatably coupled to the cabinet 11 to open and close a refrigeration compartment 111 of the cabinet 11, in which items are taken in and out.

[0071] For example, the door body is coupled to the cabinet 11 by a hinge assembly (not shown), so that the door body can rotate with respect to the cabinet 11, thereby opening or closing an opening of the refrigeration compartment 111. When the door body is opened, a user can put items into or take items out of the refrigeration compartment 111 through the opening. When the door body is closed, the items can be stored at a low temperature in the refrigeration compartment 111.

[0072] In an embodiment, the cabinet 11 can be configured with at least two refrigeration compartments 111, which can be arranged in a width direction of the refrigerator 10. Among them, the refrigeration compartment 111 on the left side of the refrigerator 10 is, for example, a freezer compartment, which can be provided with one door body or two door bodies. When the refrigeration compartment 111 on the left side of the refrigerator 10 is provided with one door body, the refrigerator 10 is called a single-door refrigerator. When the refrigeration compartment 111 on the left side of the refrigerator 10 is provided with two door bodies, the refrigerator 10 is called a double-door refrigerator, and the two door bodies can be rotatably coupled to the two sides of the cabinet 11 in a horizontal direction. The two door bodies can rotate in opposite directions with respect to the cabinet 11 to open or close the refrigeration compartment 111 above.

[0073] For example, the refrigeration compartment 111 on the right side of the refrigerator 10 is, for example, a refrigeration compartment, which can be provided in a single-door form or a double-door form, without limitation.

[0074] In some embodiments, the refrigerator 10 further includes a drawer 13. The number of the drawer 13 can be one or more, for example, two, three, four, or more. When provided as a plurality of drawers 13, the plurality of drawers 13 can be arranged in a width direction of the refrigerator 10, in a height direction of the refrigerator 10, or in other manners, without limitation.

[0075] Among them, the drawer 13 is slidably arranged inside the refrigeration compartment 111 in a front-rear direction to be able to be pulled out of or inserted into the refrigeration compartment 111 through an opening. In this embodiment, the drawer 13 is located in the refrigeration compartment or the freezer compartment. A user can pull the drawer 13 out of the refrigeration compartment 111, place items in the drawer 13, or take items out of the drawer 13. The user can push the drawer 13 into the refrigeration compartment 111 to store the items in the drawer 13 at a low temperature.

[0076] Optionally, the outer wall of the drawer 13 is provided with a sliding rail 131, which is in sliding cooperation with a rail on the inner wall of the refrigeration compartment 111. Under the guidance of the sliding rail 131 and the rail, the drawer 13 stably moves in the front-rear direction.

[0077] Optionally, when the drawer 13 is provided in multiple, the multiple drawers 13 can be arranged in the vertical direction in one refrigeration compartment 111 of the refrigerator 10, or can be arranged in multiple refrigeration compartments 111, respectively. In this embodiment, the drawer 13 arranged in one refrigeration compartment 111 will be taken as an example for expansion. In this way, each drawer 13 has an installation environment that meets the requirement of being ejected from the corresponding refrigeration compartment 111.

[0078] Please refer to Figure 3 and Figure 4 On the basis of the foregoing embodiment, the drawer 13 is provided with a first locking assembly 132. The drawer 13 has a locked position and an unlocked position. As shown in Figures 3 to 5 .

[0079] Please refer to Figure 1 , Figures 3 to 5 The refrigerator 10 further comprises a retractable device 14. The retractable device 14 is arranged in the interior of the refrigeration compartment 111, and is located between the rear side of the drawer 13 and the rear side of the refrigeration compartment 111.

[0080] The retractable device 14 comprises a base 141. The base 141 is connected to the cabinet 11.

[0081] As an example, the base 141 is provided with a first mounting portion 1411. The first mounting portion 1411 includes, but is not limited to, a mounting plate, a mounting block, a support column, or a mounting seat, etc. The first mounting portion 1411 is connected and fixed to the bottom wall or the side wall of the refrigeration compartment 111, so as to realize that the base 141 is fixedly arranged in the interior of the refrigeration compartment 111 of the cabinet 11. The connection mode of the first mounting portion 1411 and the inner wall of the refrigeration compartment 111 includes, but is not limited to, being connected by fasteners such as screws, pins, rivets, or clamping pieces, and can also be connected by adhesion or welding, which is not limited herein.

[0082] As an example, the base 141 is provided with a second mounting portion 1412. The specific structure of the second mounting portion 1412 is similar to that of the first mounting portion 1411. The second mounting portion 1412 can be directly connected and fixed to the rear wall of the refrigeration compartment 111, or can be connected and fixed to the air duct assembly 12, that is, indirectly connected and fixed to the rear wall of the refrigeration compartment 111, so as to realize that the base 141 is fixedly arranged in the interior of the refrigeration compartment 111 of the cabinet 11.

[0083] In the embodiment, the base 141 is provided with both the first mounting portion 1411 and the second mounting portion 1412. The first mounting portion 1411 is connected and fixed to the bottom wall or the side wall of the refrigeration compartment 111, and the second mounting portion 1412 is directly or indirectly connected and fixed to the rear wall of the refrigeration compartment 111. In this way, the base 141 can be fixedly arranged inside the refrigeration compartment 111 of the cabinet 11, and the mounting stability inside the cabinet 11 is high.

[0084] The telescopic device 14 further comprises a second locking assembly 142 and an energy storage assembly 143. The second locking assembly 142 is connected to the base 141, and the second locking assembly 142 is locked with the first locking assembly 132. The energy storage assembly 143 is connected to the base 141, and the energy storage assembly 143 is in abutment with the drawer 13.

[0085] When the drawer 13 is in the locked position, the first locking assembly 132 and the second locking assembly 142 are locked with each other, the energy storage assembly 143 is in the energy storage state and is locked; when the drawer 13 is pressed to move from the locked position to the unlocked position, the first locking assembly 132 and the second locking assembly 142 are switched to the unlocked state, the energy storage assembly 143 moves to the unlocked state, and the energy storage assembly 143 moves the drawer 13 out of the refrigeration compartment 111 by its own elastic force.

[0086] In use of the above refrigerator 10, when the drawer 13 needs to be opened, the drawer 13 is pressed to move from the locked position to the unlocked position, the first locking assembly 132 and the second locking assembly 142 are switched to the unlocked state, in other words, the second locking assembly 142 releases the locking of the first locking assembly 132. And since the energy storage assembly 143 also moves from the locked state to the unlocked state, the energy storage assembly 143 can move the drawer 13 out of the refrigeration compartment 111 by its own elastic force.

[0087] Conversely, when the drawer 13 needs to be closed, the drawer 13 is pushed into the refrigeration compartment 111 to move to the locked position, the first locking assembly 132 and the second locking assembly 142 are locked with each other, the second locking assembly 142 plays a limiting role on the first locking assembly 132, and the drawer 13 can be prevented from being pulled out of the refrigeration compartment 111. In addition, the drawer 13 is pressed to act on the energy storage assembly 143, so that the energy storage assembly 143 is switched to the energy storage state, and the energy storage assembly 143 can store elastic potential energy. In addition, the energy storage assembly 143 is locked in the energy storage state, so as to prevent the drawer 13 from being mistakenly pushed out due to its own elastic force.

[0088] It can be seen that, under the mutual coordination of the first locking assembly 132, the second locking assembly 142, and the force storage assembly 143, the drawer 13 can be stably and reliably closed, and the drawer 13 can be automatically popped out outward by pressing operation when the drawer 13 needs to be opened, without the need of a motor or other power mechanism for driving, so that the overall structure is relatively simple, the cost is low, and the maintainability is high, which can be applicable to middle and low-end refrigerators 10, and solves the problem that the electrically-driven automatic drawer 13 is high in cost and only applicable to some high-end refrigerators 10.

[0089] It should be noted that, in the present embodiment, the drawer 13 can be pressed in the front-to-back direction by hand, by foot, or by other auxiliary tools.

[0090] For example, the first locking assembly 132 and the second locking assembly 142 are both provided in multiple numbers. The multiple first locking assemblies 132 and the multiple second locking assemblies 142 are arranged in one-to-one correspondence. Each first locking assembly 132 is arranged, for example, at the rear side of the drawer 13, and each second locking assembly 142 is arranged, for example, at the front side of the base 141. When the drawer 13 in the open state is pushed into the refrigerating compartment 111, each first locking assembly 132 and the corresponding each second locking assembly 142 are locked to each other, so that the drawer 13 can be stably locked in the refrigerating compartment 111, avoiding automatic popping out of the drawer 13. When the drawer 13 is pressed, the drawer 13 can drive each first locking assembly 132 to move relative to the corresponding each second locking assembly 142, so that each first locking assembly 132 and the corresponding second locking assembly 142 are switched to the unlocked state, so that the drawer 13 can be moved outwards under the elastic force of the force storage assembly 143, without being interfered by the second locking assembly 142.

[0091] As a specific example, the first locking assembly 132 and the second locking assembly 142 are both provided in two, and the two first locking assemblies 132 and the two second locking assemblies 142 are provided in one-to-one correspondence. Specifically, the two first locking assemblies 132 are arranged on opposite sides of the rear side of the drawer 13. Alternatively, the two first locking assemblies 132 can be arranged on opposite sides of the left and right of the rear side of the drawer 13, or on opposite sides of the top and bottom. Similarly, the two second locking assemblies 142 are arranged on opposite sides of the front side of the base 141. Alternatively, the two second locking assemblies 142 can be arranged on opposite sides of the left and right of the front side of the base 141, or on opposite sides of the top and bottom. In this way, on the one hand, the number of the first locking assembly 132 and the second locking assembly 142 is large, which satisfies the requirement of locking the drawer 13 inside the refrigeration compartment 111 when the drawer 13 is closed; on the other hand, the number of the first locking assembly 132 and the second locking assembly 142 is not too large to make the overall structure complex, in other words, the number of the first locking assembly 132 and the second locking assembly 142 is small, thereby simplifying the overall structure.

[0092] Of course, as some optional solutions, the first locking assembly 132 and the second locking assembly 142 can both be provided in one.

[0093] Please refer to Figures 5 to 7On the basis of the foregoing embodiment, the first locking assembly 132 comprises a first locking body 1321, a first locking piece 1322 and a first elastic piece 1323. The first locking body 1321 is arranged at the rear side of the drawer 13, and the first locking body 1321 is formed with a slot 13211 extending in the front-rear direction. The first locking piece 1322 is movably arranged in the first locking body 1321. The first elastic piece 1323 is connected between the first locking piece 1322 and the first locking body 1321. In addition, the second locking assembly 142 comprises a second locking body 1421 and an unlocking piece 1422. The second locking body 1421 is arranged at the front side of the base 141, and the second locking body 1421 is arranged in position corresponding to the slot 13211, the second locking body 1421 can be inserted into the slot 13211, and the second locking body 1421 is provided with a limiting portion 14211. When the first locking piece 1322 moves in the front-rear direction, the first elastic piece 1323 can be pressed and moved to the side of the limiting portion 14211 away from the drawer 13. When the side of the limiting portion 14211 away from the drawer 13 abuts against the first locking piece 1322, the drawer 13 can be prevented from being separated from the refrigeration compartment 111. The unlocking piece 1422 is arranged on the second locking body 1421, and the unlocking piece 1422 is located on the side of the limiting portion 14211 away from the drawer 13. When the first locking piece 1322 moves in the front-rear direction, the first elastic piece 1323 can be pressed and moved to the side of the unlocking piece 1422 away from the drawer 13. When the first locking piece 1322 is located on the side of the unlocking piece 1422 away from the drawer 13, the unlocking piece 1422 and the second locking body 1421 release the locking of the first locking piece 1322, the force storage assembly 143 moves to the unlocking state, and the force storage assembly 143 moves the drawer 13 out of the refrigeration compartment 111 by the elastic force of the force storage assembly 143.

[0094] In this way, when the drawer 13 is pushed into the refrigeration compartment 111, the first locking piece 1322 can press the first elastic piece 1323 to retreat from the limiting portion 14211 during movement in the front-rear direction, so as to be smoothly moved to the side of the limiting portion 14211 away from the drawer 13, thereby realizing the movement of the drawer 13 to the locking position. When the first locking piece 1322 moves to the side of the limiting portion 14211 away from the drawer 13, the side of the limiting portion 14211 away from the drawer 13 abuts against the first locking piece 1322, thereby preventing the drawer 13 from being separated from the refrigeration compartment 111.

[0095] Further, since the second locking assembly 142 further comprises the unlocking piece 1422 arranged on the second locking body 1421, the unlocking piece 1422 is located on the side of the limiting portion 14211 away from the drawer 13, when it is needed to pull out the drawer 13 from the inside of the refrigeration compartment 111, the drawer 13 is pressed, so that the first locking piece 1322 is squeezed to retreat and avoid the unlocking piece 1422 during the movement of the first locking piece 1322 along the front and back direction through the unlocking piece 1422, and then the first locking piece 1322 can be smoothly moved to the side of the unlocking piece 1422 away from the drawer 13, so as to realize the movement of the drawer 13 to the unlocking position. When the drawer 13 is located at the unlocking position, the unlocking piece 1422 and the second locking body 1421 release the locking of the first locking piece 1322, and the force storage assembly 143 moves to the unlocking state, and the force storage assembly 143 moves the drawer 13 out of the refrigeration compartment 111 by the elastic force of the force storage assembly 143.

[0096] Please refer to Figures 5 to 7 In one embodiment, the second locking body 1421 is provided with a positioning step 14212, and the positioning step 14212 is located on the side of the limiting portion 14211 away from the drawer 13. The positioning step 14212 and the limiting portion 14211 form a spacing area 144. The unlocking piece 1422 is slidably arranged on the second locking body 1421 along the front and back direction, and moves in the spacing area 144. In this way, on the one hand, during the process of pushing the drawer 13 back to the inside of the refrigeration compartment 111 from the opening position, the first locking piece 1322 moves the drawer 13 to the locking position by passing through the limiting portion 14211, and at the same time, the first locking piece 1322 can correspondingly push the unlocking piece 1422 to move towards the positioning step 14212, so that the unlocking piece 1422 does not interfere with the first locking piece 1322; on the other hand, the drawer 13 is continuously pressed to drive the unlocking piece 1422 to abut and position with the positioning step 14212, and then the first locking piece 1322 can pass through the unlocking piece 1422, and the force storage assembly 143 is simultaneously in the unlocking state, and under the action of the elastic force of the force storage assembly 143, the first locking piece 1322 drives the unlocking piece 1422 to move towards the limiting portion 14211, so that the unlocking piece 1422 is positioned and abutted with the limiting portion 14211, the distance between the unlocking piece 1422 and the limiting portion 14211 is small, and then the first locking piece 1322 can quickly pass through the unlocking piece 1422 and the limiting portion 14211, so as to realize the movement of the drawer 13 out of the refrigeration compartment 111. Compared with the fixed arrangement of the unlocking piece 1422, the first locking piece 1322 can pass through the unlocking piece 1422 and then cannot pass through the limiting portion 14211, and the adverse defects are avoided.

[0097] In some embodiments, the distance from the center axis Z of the part of the unlocking member 1422 farthest from the center axis Z of the second locking main body 1421 is S1, and the distance from the center axis Z of the part of the limiting portion 14211 farthest from the center axis Z is S2. Optionally, S1 / S2 is 0.9-1.1, specifically for example 0.9, 1, or 1.1, etc. In this way, S1 and S2 are substantially the same size, so that when the drawer 13 is in the unlocked position, the first locking member 1322 can be facilitated to pass over the unlocking member 1422 and the limiting portion 14211, so as to smoothly move the drawer 13 out of the refrigeration compartment 111.

[0098] For example, the front side of the limiting portion 14211 is provided with a first guide surface 14213, which is in guide cooperation with the first locking member 1322. In this way, when the first locking member 1322 moves along the first guide surface 14213, it can be pressed against the first elastic member 1323 to retreat and avoid the limiting portion 14211 under the guidance of the first guide surface 14213, and then smoothly move to the side of the limiting portion 14211 away from the drawer 13, so as to realize the movement of the drawer 13 to the locked position.

[0099] Optionally, the first guide surface 14213 includes but is not limited to an arc surface, an inclined surface arranged at an angle with the center axis Z, or a combination of an arc surface and an inclined surface.

[0100] For example, the rear side of the limiting portion 14211 is provided with a first limiting surface 14214, which is in limiting cooperation with the first locking member 1322. In this way, the first limiting surface 14214 and the first locking member 1322 are in limiting cooperation, which plays a locking role on the first locking member 1322, thereby playing a locking role on the drawer 13.

[0101] Optionally, the first limiting surface 14214 includes but is not limited to a vertical surface perpendicular to the center axis Z, and of course can also be a surface arranged in other regular or irregular shapes, as long as it can effectively prevent the first locking member 1322 from moving outwards towards the refrigeration compartment 111 when abutting against the first locking member 1322.

[0102] For example, the front side of the unlocking member 1422 is provided with a second guide surface 14221, which is in guide cooperation with the first locking member 1322. In this way, when the first locking member 1322 moves along the second guide surface 14221, it can be pressed against the first elastic member 1323 to retreat and avoid the unlocking member 1422 under the guidance of the second guide surface 14221, and then smoothly move to the side of the unlocking member 1422 away from the drawer 13, so as to realize the movement of the drawer 13 to the unlocked position.

[0103] Optionally, the second guide surface 14221 includes, but is not limited to, an arc surface, an inclined surface arranged at an angle with the central axis Z, or a combination of the arc surface and the inclined surface.

[0104] Illustratively, the rear side of the unlocking member 1422 is provided with a third guide surface 14222 which is guided in cooperation with the first locking member 1322. In this way, under the elastic force of the force storage assembly 143, the drawer 13 is moved outwards towards the external portion of the refrigeration compartment 111, the first locking member 1322 moves along the third guide surface 14222, and under the guidance of the third guide surface 14222, the first elastic member 1323 can be pressed to retreat and avoid the unlocking member 1422, and then can smoothly pass through the unlocking member 1422 and the limiting portion 14211, thereby realizing the movement of the drawer 13 out of the refrigeration compartment 111.

[0105] In some embodiments, the front side of the first locking member 1322 is provided with a second limiting surface 13221 which is limited in cooperation with the first limiting surface 14214 when the drawer 13 is located at the locking position. In this way, the second limiting surface 13221 and the first limiting surface 14214 are limited in cooperation with each other, so that the drawer 13 can be stably arranged at the locking position.

[0106] Optionally, the second limiting surface 13221 and the first limiting surface 14214 are both, for example, vertical surfaces perpendicular to the central axis Z, so that the second limiting surface 13221 can be in close contact with the first limiting surface 14214, which can effectively prevent the drawer 13 from moving out of the refrigeration compartment 111, and the stability of the drawer 13 inside the refrigeration compartment 111 is higher.

[0107] In some embodiments, the rear side of the first locking member 1322 is provided with a fourth guide surface 13222 which is guided in cooperation with the first guide surface 14213 or the second guide surface 14221. In this way, under the guidance of the first guide surface 14213 and the fourth guide surface 13222, the drawer 13 can be conveniently moved to the locking position, and under the guidance of the second guide surface 14221 and the fourth guide surface 13222, the drawer 13 can be conveniently moved from the locking position to the unlocking position.

[0108] Optionally, the fourth guide surface 13222 includes, but is not limited to, an arc surface, an inclined surface arranged at an angle with the central axis Z, or a combination of the arc surface and the inclined surface.

[0109] In one embodiment, the first locking member 1322 includes, but is not limited to, a locking pin, a locking rod, or a locking column.

[0110] The slot wall of the slot 13211 is formed with a through hole 13212, the first elastic member 1323 is arranged inside the through hole 13212, the first elastic member 1323 is a spring, the first locking member 1322 is arranged in the spring, one end of the first locking member 1322 extends into the slot 13211, the other end of the first locking member 1322 extends out of the first locking main body 1321 through the through hole 13212, and the other end of the first locking member 1322 is provided with a first limiting flange 13223, and the first limiting flange 13223 is limited and matched with the first locking main body 1321. The inner wall of the through hole 13212 is provided with a second limiting flange 13213, and the outer wall of the first locking member 1322 is provided with a third limiting flange 13224. The first elastic member 1323 is arranged between the second limiting flange 13213 and the third limiting flange 13224. In this way, on the one hand, under the elastic force of the first elastic member 1323, one end of the first locking member 1322 extends into the slot 13211, and the first limiting flange 13223 is limited and matched with the first locking main body 1321, thereby limiting the first locking member 1322; on the other hand, during the movement of the first locking member 1322 along the front and back through the limiting portion 14211 or the unlocking member 1422, the first locking member 1322 is pressed back by the limiting portion 14211 or the unlocking member 1422 to drive the first elastic member 1323 to be compressed, so as to avoid the limiting portion 14211 or the unlocking member 1422, thereby smoothly passing through the limiting portion 14211 or the unlocking member 1422. After passing through the limiting portion 14211 or the unlocking member 1422, the first locking member 1322 is reset under the elastic force of the first elastic member 1323.

[0111] In other embodiments, the first locking member 1322 does not need to be arranged in the spring, and the first limiting flange 13223, the second limiting flange 13213 and the third limiting flange 13224 do not need to be arranged. Specifically, one end of the first locking member 1322 extends into the through hole 13212 and is connected with the first elastic member 1323, the first elastic member 1323 is fixed inside the through hole 13212 of the first locking main body 1321, and the other end of the first locking member 1322 extends out of the through hole 13212 and extends into the slot 13211. In this way, when the first locking member 1322 does not abut against the limiting portion 14211 or the unlocking member 1422, the first elastic member 1323 is in a natural state, the first locking member 1322 extends out of the through hole 13212 and extends into the slot 13211; when the first locking member 1322 moves along the front and back through the limiting portion 14211 or the unlocking member 1422, the first locking member 1322 is pressed back by the limiting portion 14211 or the unlocking member 1422 to drive the first elastic member 1323 to be compressed, so as to avoid the limiting portion 14211 or the unlocking member 1422, thereby smoothly passing through the limiting portion 14211 or the unlocking member 1422.

[0112] Please refer toFigure 4 、 Figure 5 and Figure 8 In one embodiment, the refrigerator 10 further comprises a pushing frame 15. The pushing frame 15 is connected with the force storage assembly 143, and the pushing frame 15 is slidably arranged on the base 141 in the front-rear direction and abuts against the drawer 13. In this way, the force storage assembly 143 can be indirectly abutted against the drawer 13 through the pushing frame 15, so that the force storage assembly 143 can be switched to the force storage state and the unlocking state when the drawer 13 moves to the locking position and the unlocking position, respectively. In addition, the pushing frame 15 is slidably arranged in the front-rear direction, so that the drawer 13 and the force storage assembly 143 can stably move in the front-rear direction, respectively.

[0113] On the basis of the foregoing embodiment, the pushing frame 15 comprises a guide rod 151 and a pushing piece 152. The guide rod 151 is slidably arranged on the base 141 in the front-rear direction. The pushing piece 152 extends in the left-right direction of the drawer 13 and abuts against the drawer 13, and the pushing piece 152 is connected with the guide rod 151. In this way, since the pushing piece 152 extends in the left-right direction of the drawer 13, the pushing piece 152 abuts against the drawer 13 more in the left-right direction of the drawer 13, so that the drawer 13 can be more stably moved out of the refrigeration compartment 111. In addition, when the drawer 13 enters the refrigeration compartment 111, the pushing piece 152 and the guide rod 151 can act on the force storage assembly 143, so that the force storage assembly 143 can stably move in the front-rear direction to store force.

[0114] Optionally, the pushing piece 152 includes but is not limited to a pushing rod, a pushing plate, a pushing column, a pushing block, etc., and can be flexibly adjusted and arranged according to actual needs.

[0115] In one embodiment, the pushing frame 15 further comprises an auxiliary support 153. One end of the auxiliary support 153 is rotationally connected with the pushing piece 152, and the other end of the auxiliary support 153 is slidably arranged on the front side of the base 141 and is arranged at an angle with the front side of the base 141. In this way, during the interaction between the drawer 13 and the force storage assembly 143, the auxiliary support 153 can play a supporting role, so that the transmission stability between the drawer 13 and the force storage assembly 143 is improved.

[0116] Optionally, the auxiliary support 153 is not limited to one, but can be two, three or more. In this embodiment, the auxiliary support 153 is two, for example, and the guide rod 151 is connected with the middle part of the pushing piece 152, and the two auxiliary supports 153 are arranged on opposite sides of the guide rod 151, respectively.

[0117] Optionally, the auxiliary support 153 includes, but is not limited to, a support rod, a support column, a support plate, or the like.

[0118] Optionally, the front side of the base 141 is provided with a side panel 1413, and the auxiliary support 153 is slidably arranged on the side panel 1413 along the left-right direction of the drawer 13. The side panel 1413 is provided with a slide channel extending along the left-right direction, and the auxiliary support 153 is provided with a sliding part slidably arranged in the slide channel.

[0119] In one embodiment, the force storage assembly 143 includes a sliding block 1431, a second locking member 1432, and a second elastic member 1433. The sliding block 1431 is slidably arranged on the base 141 along the front-rear direction, and the sliding block 1431 is formed with an annular guide portion 1434 provided with a locking position and a complete release position.

[0120] Optionally, the guide portion 1434 includes, but is not limited to, a guide groove.

[0121] One end of the second locking member 1432 is rotationally connected to the base 141, and the other end of the second locking member 1432 is provided with a movable part 1435 capable of moving along the guide portion 1434. The locking position, the complete release position, and the connection position of the second locking member 1432 and the base 141 are sequentially arranged on the same straight line along the front-rear direction.

[0122] The second elastic member 1433 is connected between the sliding block 1431 and the base 141, and is used to move the sliding block 1431 along the front-rear direction, thereby driving the drawer 13 to move out of the refrigeration compartment 111.

[0123] The locking position is the position where the movable part 1435 is located in the guide portion 1434 as shown in Figures 3 to 5 The complete release position is the position where the movable part 1435 is located in the guide portion 1434 as shown in Figure 8 and Figure 9 .

[0124] The locking position is specifically an end of the guide portion 1434 close to the drawer 13. Optionally, a wall of the guide groove is formed with a locking recess 1436 recessed towards a direction away from the drawer 13 at the locking position. When the movable portion 1435 moves along the guide portion 1434 to the locking recess 1436, the second elastic member 1433 is in a compressed state and stores a relatively large elastic potential energy, the locking recess 1436 locks the movable portion 1435, at this time, the force storage assembly 143 is in a force storage state and is locked, the drawer 13 is in the locked position and cannot be automatically ejected; when the drawer 13 is pressed in the front-rear direction, the movable portion 1435 will move out of the locking recess 1436, at this time, the force storage assembly 143 is unlocked, and the first locking assembly 132 and the second locking assembly 142 are switched to the unlocked state, under the elastic force of the second elastic member 1433, the slider 1431 moves along the base 141 and drives the drawer 13 to move out of the refrigeration compartment 111, so as to realize automatic ejection of the drawer 13.

[0125] When the movable portion 1435 moves along the guide portion 1434 to the complete release position, the elastic force of the second elastic member 1433 is completely released and cannot continue to drive the slider 1431 to move, and at the same time, the movable portion 1435 limits the slider 1431, preventing the slider 1431 from disengaging from the second locking assembly 1432.

[0126] Please refer to Figure 10 and Figure 11 In an embodiment, the pushing frame 15 is provided as at least two. The two pushing frames 15 are arranged in the up-down direction and are spaced apart. In this way, the at least two pushing members 152 are synchronously in abutting cooperation with the drawer 13, the force on different parts of the rear side of the drawer 13 in the up-down direction is relatively more balanced, and the stability of the drawer 13 and the force storage assembly 143 in the front-rear direction is improved.

[0127] In the embodiment, the pushing frame 15 is provided as two, for example. For the pushing frame 15 on the upper side, the guide rod 151 penetrates through the front side plate and is slidably arranged on the base 141, and the guide rod 151 is connected with the force storage assembly 143 after penetrating through the front side plate; for the pushing frame 15 on the lower side, the pushing frame 15 further comprises a connecting seat 154, the connecting seat 154 is connected with the force storage assembly 143, and the guide rod 151 is connected with the connecting seat 154. In addition, the base 141 is further provided with a supporting portion 1414, and the guide rod 151 is slidably arranged on the supporting portion 1414 in the front-rear direction.

[0128] In the embodiment, the pushing frame 15 on the lower side is provided with the pushing member 152, and the pushing member 152 on the pushing frame 15 on the lower side is arranged more forward than the pushing member 152 on the pushing frame 15 on the upper side, so that the pushing members 152 of the two pushing frames 15 can be synchronously in abutting cooperation with the rear side of the drawer 13.

[0129] Referring to Figures 11 to 13 In one embodiment, the telescopic device 14 further comprises a third elastic member 145. The third elastic member 145 is connected to the base 141, and the third elastic member 145 is in abutting engagement with the drawer 13 in the front-rear direction. In this way, when the drawer 13 is continuously pressed from the locked position to the unlocked position, the third elastic member 145 abuts against the drawer 13, thereby buffering the drawer 13. In addition, when the drawer 13 is in the unlocked position, not only does the force storage assembly 143 provide elastic force to move the drawer 13 out of the refrigeration compartment 111, but the third elastic member 145 also provides elastic force to move the drawer 13 out of the refrigeration compartment 111. It can be seen that, under the mutual action of the force storage assembly 143 and the third elastic member 145, the opening operation of the drawer 13 is more stable and reliable.

[0130] On the basis of the foregoing embodiment, the third elastic member 145 is not limited to one, but can also be provided in multiple, for example, two, three, or more. Specifically, the third elastic member 145 is provided in two, and the two third elastic members 145 are respectively located on opposite sides of the push frame 15. In this way, when the two third elastic members 145 abut against the drawer 13, the drawer 13 is balanced in force, and the movement stability is improved.

[0131] The third elastic member 145 includes, but is not limited to, a spring or an elastic block, etc.

[0132] The third elastic member 145 and the second locking body 1421 are both connected to the front side plate. The length of the third elastic member 145 in the front-rear direction is consistent with that of the second locking body 1421. In this way, when the second locking assembly 142 and the first locking assembly 132 are locked with each other, the compression deformation amount of the third elastic member 145 is small, or even 0, and the extrusion force of the third elastic member 145 on the drawer 13 is small, thereby preventing the drawer 13 from automatically popping out.

[0133] Referring to Figure 14 and Figure 15 In one embodiment, the refrigerator 10 further comprises a limiting mechanism 16. The limiting mechanism 16 is arranged on the bottom wall or the side wall of the refrigeration compartment 111, and the outer wall of the drawer 13 is provided with a limiting portion 133 in limiting engagement with the limiting mechanism 16.

[0134] The limiting mechanism 16 comprises a limiting piece 161 and a fourth elastic piece 162. The limiting piece 161 is arranged obliquely relative to the outer wall of the drawer 13, the front end of the limiting piece 161 is rotationally connected to the inner wall of the refrigeration compartment 111, and the rear end of the limiting piece 161 is slidingly matched with the outer wall of the drawer 13. The limiting piece 161 is connected with the fourth elastic piece 162, the fourth elastic piece 162 is connected with the inner wall of the refrigeration compartment 111, and the fourth elastic piece 162 makes the rear end of the limiting piece 161 abut against the outer wall of the drawer 13. The limiting portion 133 is a limiting groove formed in the outer wall of the drawer 13. When the drawer 13 is moved out to the target position of the refrigeration compartment 111, the rear end of the limiting piece 161 can enter the inside of the limiting groove under the elastic force of the fourth elastic piece 162 and abut against the groove wall of the limiting groove to limit the drawer 13 from moving out of the refrigeration compartment 111; when the drawer 13 is pushed into the refrigeration compartment 111 from the target position, the rear end of the limiting piece 161 can exit the limiting groove. In this way, on the one hand, during the outward movement of the drawer 13 by the force storage assembly 143, the limiting mechanism 16 limits the drawer 13 from moving out of the refrigeration compartment 111. Specifically, when the drawer 13 is moved out to the target position, for example, the position where the rear side of the drawer 13 is close to the opening of the refrigeration compartment 111, the rear end of the limiting piece 161 can enter the inside of the limiting groove and abut against the groove wall of the limiting groove, thereby limiting the drawer 13 from continuously moving out of the refrigeration compartment 111; on the other hand, when the drawer 13 is pushed into the refrigeration compartment 111 from the target position, the rear end of the limiting piece 161 can exit the limiting groove under the extrusion of the drawer 13, so that the rear end of the limiting piece 161 does not limit the movement of the drawer 13 towards the inside of the refrigeration compartment 111, thereby enabling the drawer 13 to smoothly enter the refrigeration compartment 111.

[0135] It should be noted that the fourth elastic piece 162 includes but is not limited to a spring or a spring sheet, and can be flexibly adjusted and arranged according to actual needs.

[0136] In an embodiment, the front groove wall of the limiting groove is provided with a fifth guide surface 1331, and the fifth guide surface 1331 is guidingly matched with the rear end of the limiting piece 161. In this way, when the drawer 13 is pushed into the refrigeration compartment 111 from the target position, the rear end of the limiting piece 161 can smoothly exit the limiting groove under the guidance of the fifth guide surface 1331.

[0137] For example, the limiting groove is arranged as a triangular groove. In other words, the limiting groove comprises a front groove wall and a rear groove wall, and the front groove wall and the rear groove wall are arranged at an angle. The angle between the front groove wall and the outer wall of the drawer 13 is greater than the angle between the rear groove wall and the outer wall of the drawer 13, for example.

[0138] When it is needed to close the drawer 13, due to the different angles of the triangular limiting recesses, the inclination angle of the rear groove wall is small, under the action of the rear pushing force, the limiting piece 161 rotates from the convex state to the concave state, which can unlock the limiting state, and the drawer 13 can be closed.

[0139] For example, the rear end outer wall of the limiting piece 161 is provided as an arc surface. In this way, the arc surface can reduce friction during the abutment of the rear end of the limiting piece 161 with the outer wall of the drawer 13, so that the movement in the front-rear direction is more smooth and stable.

[0140] For example, the outer wall of the drawer 13 is further provided with a sliding groove 134 extending in the front-rear direction, the sliding groove 134 is in communication with the limiting groove, the depth of the sliding groove 134 is smaller than the depth of the limiting groove, and the rear end of the limiting piece 161 is slidably arranged in the sliding groove 134. In this way, since the rear end of the limiting piece 161 is slidably arranged in the sliding groove 134 in the front-rear direction, the sliding groove 134 plays a guiding role on the limiting piece 161, on the one hand, the limiting piece 161 does not limit the front-rear movement of the drawer 13; on the other hand, when the drawer 13 moves to the target position, the rear end of the limiting piece 161 can normally extend into the inside of the limiting groove, and plays a limiting role on the drawer 13.

[0141] In one specific embodiment, the limiting mechanism 16 is specifically arranged on the bottom wall of the refrigeration compartment 111, and the sliding groove 134 and the limiting groove are correspondingly formed on the bottom wall of the drawer 13.

[0142] It should be noted that the "first locking main body 1321" in the present embodiment can be "a part of the drawer 13", that is, the "first locking main body 1321" is integrally formed with "other parts of the drawer 13"; or it can be a separate component that can be separated from "other parts of the drawer 13", that is, the "first locking main body 1321" can be independently manufactured, and then combined with "other parts of the drawer 13" to form an integral whole.

[0143] It should be noted that the "second locking main body 1421" in the present embodiment can be "a part of the base 141", that is, the "second locking main body 1421" is integrally formed with "other parts of the base 141"; or it can be a separate component that can be separated from "other parts of the base 141", that is, the "second locking main body 1421" can be independently manufactured, and then combined with "other parts of the base 141" to form an integral whole.
