Description

Technical Field

[0001] The invention relates to the technical field of refrigeration equipment, and in particular to a refrigerator with a thawing function. Background Art

[0002] Refrigerators are a common electrical appliance in people's daily lives. They can maintain a low-temperature environment in the storage room through structures such as compressors or semiconductor refrigeration components, thereby extending the shelf life of food and other items placed in the storage room.

[0003] Among them, the storage compartments such as freezer or refrigeration of the refrigerator can be opened or closed through a door body connected to the box body, which is convenient for taking and placing items and maintaining a low temperature environment in the storage compartment. In the related technical scheme, the refrigerator can also be provided with a compartment with a temperature-changing function, in which preset items can be placed for freezing, and when necessary, the temperature of the temperature-changing compartment can also be increased to thaw the frozen preset items.

[0004] However, in the above manner, all items in the variable temperature room will be thawed at the same time, which is inconvenient for thawing individual preset items, or the entire variable temperature room will be occupied for thawing, which is not very convenient. Summary of the invention

[0005] The object of the present invention is to provide a refrigerator with a thawing function, aiming to solve the problem of inconvenience in thawing through a variable temperature compartment.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme:

[0007] On the one hand, the present invention provides a refrigerator with a thawing function, including a box body and a door body, wherein a first accommodating chamber, a second accommodating chamber and a thawing through hole are arranged in the box body, the temperature of the first accommodating chamber is lower than the temperature of the second accommodating chamber, and the door body is used to open or close the first accommodating chamber and the second accommodating chamber. The thawing through hole has an open state and a closed state. When the thawing through hole is in the open state, the thawing through hole connects the first accommodating chamber and the second accommodating chamber, and the pre-thawed items in the first accommodating chamber enter the second accommodating chamber through the thawing through hole to be thawed under the action of gravity. When the thawing through hole is in the closed state, the thawing through hole separates the first accommodating chamber and the second accommodating chamber.

[0008] On the other hand, the present invention provides a refrigerator with a thawing function, comprising a cabinet door and a first door panel. A first accommodating chamber, a second accommodating chamber and a thawing through hole are provided in the cabinet, and the temperature of the first accommodating chamber is lower than the temperature of the second accommodating chamber. The door is used to open or close the first accommodating chamber and the second accommodating chamber. The first door panel is installed close to the thawing through hole, and the thawing through hole has an open state and a closed state. When the thawing through hole is in the open state, the first accommodating chamber is connected to the second accommodating chamber through the thawing through hole, and the pre-thawed items in the first accommodating chamber enter the second accommodating chamber through the thawing through hole to be thawed under the action of gravity. When the thawing through hole is in the closed state, the thawing through hole separates the first accommodating chamber and the second accommodating chamber.

[0009] In this way, taking the first chamber as a freezing chamber and the second chamber as a refrigerating chamber as an example, by setting the thawing through hole, the thawing through hole can be opened by the first door panel so that the pre-thawed items in the freezing chamber fall into the refrigerating chamber through the thawing through hole under the action of gravity for thawing. There is no need to set up an additional temperature-changing chamber, and the temperature of the first chamber will not be adjusted and changed. The structure is simple and easy to operate. In addition, since the first door panel can also close the thawing through hole, the freezing state in the first chamber will not be affected.

[0010] In some embodiments, the refrigerator with the defrosting function further includes a first door valve assembly, and the first door valve assembly includes a door frame member and a first driving member. The door frame member is installed in the first accommodating chamber and / or the second accommodating chamber, and the door frame member is arranged around the edge of the thawing through hole. The first driving member is installed in the first accommodating chamber or the second accommodating chamber, and the first driving member is arranged near the door frame member. The first door panel member is connected to the door frame member and the first driving member, and the driving member drives the first door panel member to move relative to the door frame member, so as to open or close the thawing through hole.

[0011] In some embodiments, the refrigerator with thawing function further includes a storage box located in the first accommodating cavity, the lower end of the storage box has an opening and is used to communicate with the thawing through hole, and the storage box is used to store pre-thawed items.

[0012] In some embodiments, the storage box includes a box body and at least one partition, the partition divides the box body into a plurality of storage cavities distributed along a first straight line direction, the storage cavities are used to store pre-thawed items, and the lower end openings of the plurality of storage cavities are used to communicate with the thawing through hole. The first straight line direction intersects with the up-down direction.

[0013] In some embodiments, the refrigerator with a thawing function further includes a second door panel and a second driving member. The second door panel is installed near the lower end opening of the storage box, and the second driving member is used to drive the second door panel to open or close the lower end opening of the storage box.

[0014] In some embodiments, when the storage box is provided with a plurality of storage cavities sequentially distributed along a first linear direction, the first linear direction intersects with the up-down direction. The second gate valve assembly further comprises a guide rail portion and a roller member, the guide rail portion extending along the first linear direction, and the guide rail portion is distributed on opposite sides of the lower end of the storage box along the second linear direction. The first linear direction is perpendicular to the second linear direction. The roller member is disposed at one end of the storage box along the first linear direction, and the roller member is connected to the second driving member. Both ends of the second door panel member along the second linear direction are inserted into the guide rail portion, and one end of the second door panel member close to the roller member along the first linear direction is connected to the roller member.

[0015] The second gate valve assembly has an open motion state and a closed motion state. When the second gate valve assembly is in the open motion state, the second driving member drives the roller member to rotate, so that the second door panel member coils around the roller member, and the second door panel member sequentially opens the lower ends of the plurality of storage cavities along the first straight line direction. When the second gate valve assembly is in the closed motion state, the second driving member drives the roller member to reverse, so that the second door panel member reversely closes the lower ends of the plurality of storage cavities along the first straight line direction.

[0016] In some embodiments, the refrigerator with a thawing function further includes a plurality of first sensors, which are arranged in one-to-one correspondence with the plurality of storage cavities, and a first sensor is installed close to a storage cavity to detect whether the lower end opening of the storage cavity is in an open state.

[0017] In some embodiments, the refrigerator with thawing function further comprises a funnel, which is located in the first accommodating cavity and arranged between the storage box and the thawing through hole. The lower end opening of the storage box is connected to the thawing through hole through the funnel.

[0018] In some embodiments, the refrigerator with thawing function further includes a thawing shelf installed in the second accommodating cavity, the thawing shelf being located below the thawing through hole in the up and down direction and being used for receiving and placing pre-thawed items.

[0019] In some embodiments, when the refrigerator with a thawing function further includes a thawing shelf, the refrigerator with a thawing function further includes a second sensor, a signal prompter, and a controller. The second sensor is disposed at the thawing shelf, and when pre-thawed items are placed on the thawing shelf, the second sensor outputs a second open state signal. The controller is connected to the second sensor and the signal prompter, and the controller is configured as follows:

[0020] The controller receives the second start-up state signal and starts the thawing timing state. When the duration of the thawing timing state is greater than or equal to the first preset duration, the controller sends a prompt signal through the signal prompter.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is satisfied.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components.

[0048] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0049] like Figure 1 As shown, Figure 1 A schematic diagram of the three-dimensional structure of a refrigerator with a thawing function (hereinafter referred to as refrigerator 100) provided in an embodiment of the present application. The refrigerator 100 may include a box body 1 and a door body 2. The box body 1 may be a box-shaped structure that is approximately a rectangular parallelepiped, or may be other structures. The box body 1 may be connected to the door body 2, such as by hinged installation.

[0050] like Figure 2 As shown, the box body 1 may include an outer shell 11, an inner liner 12, and a heat insulation layer (not shown in the figure) filled between the outer shell 11 and the inner liner 12. The box body 1 may be provided with a first accommodating chamber 13 and a second accommodating chamber 14 through the inner liner 12. The first accommodating chamber 13 and the second accommodating chamber 14 may be distributed in the up-down direction, such as the first accommodating chamber 13 may be located above the second accommodating chamber 14. The temperature of the first accommodating chamber 13 may be lower than the temperature of the first accommodating chamber 13. For example, the first accommodating chamber 13 is a freezing chamber, and the second accommodating chamber 14 is a refrigerating chamber. By providing the outer shell 11 and the heat insulation layer outside the inner liner 12, the heat preservation and heat insulation performance of the box body can be improved while improving the structural strength of the box body 1.

[0051] Exemplarily, the door body 2 can be hinged to the box body 1, so that the door body 2 can open or close the first accommodating cavity 13 and the second accommodating cavity 14 by rotation, so that the first accommodating cavity 13 and the second accommodating cavity 14 have good air tightness and heat insulation when they are closed. In addition, the door body 2 can also be connected to the box body 1 by hinges or guide rails, so that the door body 2 can open or close the first accommodating cavity 13 and the second accommodating cavity 14 by rotation and / or translation, which is not limited in the present application.

[0052] Since the preset items frozen in the freezer usually need to be thawed before use, the preset items in the freezer can be directly taken out of the freezer and thawed by indoor air or tap water, but the thawing time is long and it is not convenient to use them in time.

[0053] In the related technical solution, a variable temperature compartment may be provided in the refrigerator, that is, the temperature of the variable temperature compartment can be adjusted and changed between the refrigeration temperature and the freezing temperature. Preset items can be placed in the variable temperature compartment and frozen and stored at the freezing temperature. Before use, the temperature of the variable temperature compartment can be pre-adjusted to the refrigeration temperature so that the preset items frozen in the variable temperature compartment can be thawed in advance.

[0054] However, in the process of thawing the frozen preset items by means of the variable temperature chamber, all the items in the variable temperature chamber will be thawed at the same time, which is inconvenient to thaw individual preset items, or the entire variable temperature chamber will be occupied for thawing, which is not very convenient.

[0055] Based on this, Figure 2 As shown, a thawing through hole 15 may be further provided in the box body 1, and the thawing through hole 15 may be used to connect the first accommodating chamber 13 and the second accommodating chamber 14. Taking the first accommodating chamber 13 being located above the second accommodating chamber 14 as an example, the thawing through hole 15 may be opened on the lower side wall of the first accommodating chamber 13, that is, the thawing through hole 15 is also opened on the upper side wall of the second accommodating chamber 14, wherein the thawing through hole 15 may have an open state and a closed state.

[0056] Exemplarily, when the thawing through hole 15 is in an open state, the thawing through hole can connect and conduct the first accommodating chamber 13 and the second accommodating chamber 14, so that the pre-thawed items in the first accommodating chamber 13 can enter the second accommodating chamber 14 through the thawing through hole 15 under the action of gravity for thawing. Subsequently, the thawing through hole 15 can be set in a closed state so that the thawing through hole 15 can separate the first accommodating chamber 13 and the second accommodating chamber 14, thereby avoiding affecting the refrigerated state of the first accommodating chamber 13 and the frozen state of the second accommodating chamber 14 through the thawing through hole, and preventing other items in the first accommodating chamber 13 from entering the second accommodating chamber 14.

[0057] Thus, taking the first accommodating chamber 13 as a freezing chamber and the second accommodating chamber 14 as a refrigerating chamber as an example, by setting the thawing through hole 15, the pre-thawed items in the freezing chamber can be opened to fall into the refrigerating chamber through the thawing through hole 15 under the action of gravity for thawing. No additional temperature-changing chamber is required, and the temperature of the first accommodating chamber 13 will not be adjusted. The structure is simple and easy to operate, and the freezing state in the first accommodating chamber 13 will not be affected.

[0058] like Figure 3 As shown, taking the case where the door body 2 is located on the front side of the box body 1 as an example, the first accommodating chamber 13 and the second accommodating chamber 14 can also be distributed in sequence along the left and right directions. Taking the case where the first accommodating chamber 13 is located on the left side of the second accommodating chamber 14 as an example, a thawing through hole 15 (such as Figure 2 shown).

[0059] At this time, in order to facilitate the pre-thawed items in the first accommodating chamber 13 to enter the second accommodating chamber 14 through the thawing through hole 15 under the action of gravity, a storage piece or the like can be provided in the first accommodating chamber 13 for placing the pre-thawed items. When the thawing through hole 15 is in an open state, the pre-thawed items placed on the storage piece can pass through the thawing through hole 15 under the action of gravity and fall into the second accommodating chamber 14.

[0060] In addition, if Figure 2 As shown, the box body 1 may further include a thawing shelf 16, which may be a frame structure or a plate structure. The thawing shelf 16 may be installed in the second accommodating chamber 14, and the thawing shelf 16 may be located below the thawing through hole 15 in the up-down direction, so as to receive and store the pre-thawed items dropped from the thawing through hole 15 into the second accommodating chamber 14 for thawing.

[0061] In some embodiments, Figure 3 As shown, the box body 1 may also be provided with a third accommodating chamber 17, taking the first accommodating chamber 13, the second accommodating chamber 14 and the third accommodating chamber 17 as three independent chambers as an example. The first accommodating chamber 13 may be a freezing chamber, the second accommodating chamber 14 may be a refrigerating chamber, and the third accommodating chamber 17 may be one of a variable temperature chamber, a freezing chamber or a refrigerating chamber.

[0062] Alternatively, the first accommodating chamber 13 may be a variable temperature chamber and the second accommodating chamber 14 may be a refrigerating chamber, and the temperature of the variable temperature chamber only needs to be set lower than the temperature of the refrigerating chamber during the thawing process, such as the variable temperature chamber can be in a freezing state to freeze the pre-thawed items. Alternatively, the first accommodating chamber 13 may be a freezing chamber and the second accommodating chamber 14 may be a variable temperature chamber, and the temperature of the variable temperature chamber only needs to be set higher than the temperature of the freezing chamber during the thawing process, such as the variable temperature chamber can be in a refrigerating state to refrigerate and thaw the pre-thawed items.

[0063] In order to facilitate opening or closing the thawing through hole 15, Figure 4 and Figure 5 As shown, the refrigerator 100 may further include a first door valve assembly 3. Figure 6 As shown, the first door valve assembly 3 may include a door frame member 31 , a first driving member 32 and a first door panel member 33 .

[0064] Combination Figure 5 and Figure 6 , on the upper and lower sides of the edge of the thawing through hole 15, a door frame member 31 can be installed on one side, so that the door frame member 31 can be arranged around the edge of the thawing through hole 15. For example, the door frame member 31 can be located in the second accommodating chamber 14, that is, the door frame member 31 can be installed at the lower edge of the thawing through hole 15.

[0065] In addition, the door frame 31 can also be installed in the first accommodating chamber 13, that is, the door frame 31 can be installed at the upper edge of the thawing through hole 15. Alternatively, the door frame 31 can also be installed in both the first accommodating chamber 13 and the second accommodating chamber 14, that is, the door frame 31 can be installed at the upper edge and the lower edge of the thawing through hole 15 at the same time, which is not limited.

[0066] Continue to refer to Figure 5 and Figure 6 The first driving member 32 installed near the door frame member 31 can be located at the rear side of the door frame member 31, so as to prevent the protruding first driving member 32 from leaking forward. The first driving member 32 can be in the same accommodating chamber (such as the first accommodating chamber 13 or the second accommodating chamber 14) as the door frame member 31, and it is sufficient that the first driving member 32 can drive the first door panel member 33 to open or close the thawing through hole 15.

[0067] like Figure 6 and Figure 7 As shown, the first door panel 33 can be hingedly installed with the door frame 31, so that the first driving member 32 can drive the first door panel 33 to rotate around the door frame 31 through gears, belts or transmission shafts. Figure 5 The thawing through hole 15 is opened in the up-down direction (ie, the central axis is parallel to the up-down direction), and the first gate valve assembly 3 is located below the thawing through hole 15 as an example:

[0068] like Figure 6 As shown, when the first driving member 32 drives the first door panel 33 to be in a horizontal state perpendicular to the up and down direction, the first door panel 33 can be closed. Figure 5 Thus, while preventing the pre-thawed items from entering the second accommodating chamber 14, the cold air with a lower temperature in the first accommodating chamber 13 can be effectively isolated from entering the second accommodating chamber 14 to affect the refrigeration effect and thawing effect of the second accommodating chamber 14.

[0069] like Figure 7 As shown in FIG. 1 , when the first driving member 32 drives the first door panel member 33 to rotate downward around its hinge axis from a horizontal state, the thawing through hole 15 (such as Figure 5 When the first door panel 33 rotates to be parallel to the central axis of the thawing through hole 15, the lower end of the thawing through hole 15 is fully opened by the first door panel 33, so that the pre-thawed items can smoothly enter the second accommodating chamber 14 through the thawing through hole for thawing.

[0070] In the above embodiment, if Figure 7 As shown, the hinge axis between the first door panel member 33 and the door frame member 31 can be arranged parallel to the front-to-back direction or the left-to-right direction, and the angle formed by the hinge axis and the front-to-back direction can also be an acute angle. It is only necessary to adjust the setting positions of the first driving member 32 and the thawing hole 15 accordingly.

[0071] In some other embodiments, the first driving member 32 can also drive the first door panel member 33 to move back and forth in the front-to-back or left-to-right direction. At this time, the door frame member 31 can be a corresponding guide rail or guide rail groove structure, and can also open or close the thawing hole 15 at the corresponding end.

[0072] It should be noted that the door frame 31 can also be an integrated structure with the inner container 12, that is, the inner container 12 can form a door frame 31 at the edge of the thawing through hole 15 for connecting the first door panel 33. In the embodiment of the present application, the door frame 31, the first door panel 33 and the first driving member 32 can all be regarded as part of the overall structure of the refrigerator 100.

[0073] In some embodiments, Figure 5 As shown, the box body 1 may further include a tray 18, and the tray 18 may be located on the thawing shelf 16, that is, the tray 18 may be located in the second accommodating chamber 14. The tray 18 may be arranged close to the thawing through hole 15. For example, if the thawing through hole 15 is opened in the up-down direction, the tray 18 may be located below the thawing through hole 15 and aligned with the thawing through hole 15, so as to facilitate the receiving and placing of the pre-thawed items dropped from the thawing through hole 15.

[0074] Continue to refer to Figure 5 The refrigerator 100 may further include a storage box 4, which may be located in the first accommodating chamber 13. An opening structure may be provided at the lower end of the storage box 4 so that the lower end of the storage box 4 may be connected to the thawing through hole 15. Since the thawing through hole 15 has an open state and a closed state, when the thawing through hole 15 is in the open state, the pre-thawed items placed in the storage box 4 may fall through the thawing through hole 15 under the action of gravity into the second accommodating chamber 14 for thawing.

[0075] It should be noted that, in the case where a storage box 4 with a lower opening connected to the thawing through hole 15 is installed in the first accommodating chamber 13, when at least one of the thawing through hole 15 and the lower opening of the storage box 4 is closed, the thawing through hole 15 is in a closed state, and the thawing through hole 15 can separate the first accommodating chamber 13 and the second accommodating chamber 14 to prevent other items in the first accommodating chamber 13 from entering the second accommodating chamber, and to prevent the mixing of cold air in the two chambers from affecting the chamber temperature.

[0076] Correspondingly, when the thawing through hole 15 is in an open state, it means that both ends of the thawing through hole 15 are in an open state, and the lower end opening of the storage box 4 is also in an open state, so that the storage box 4 can be connected to the second accommodating chamber 14 through the thawing through hole 15. At this time, the pre-thawed items can enter the second accommodating chamber 14 through the thawing through hole 15 under the action of gravity for thawing.

[0077] When the upper end of the storage box 4 is open, when the thawing through hole 15 is in an open state, the first accommodating chamber 13 can be connected to and communicated with the second accommodating chamber 14 through the storage box 4 and the thawing through hole 15 .

[0078] In order to facilitate the connection between the lower opening of the storage box 4 and the thawing through hole 15, Figure 5 and Figure 8 As shown, the refrigerator 100 may further include a funnel 5, and along the up-down direction, the main body of the funnel 5 may be located between the storage box 4 and the thawing through hole 15. The lower end opening of the storage box 4 may be connected to the thawing through hole 15 through the funnel 5, so that the pre-thawed items may smoothly enter the second accommodating chamber 14 through the lower end opening of the storage box 4, the funnel 5 and the thawing through hole 15 under the action of gravity.

[0079] Exemplarily, the funnel member 5 may be a funnel structure with an upper opening area larger than a lower opening area. When the storage box 4 and the thawing through hole 15 are arranged, since the lower opening of the storage box 4 and the thawing through hole 15 are not completely the same in outline shape and area, the arrangement of the funnel member 5 facilitates the connection and installation of the storage box 4 and the thawing through hole 15, and the funnel shape facilitates the passage of pre-thawed items.

[0080] In some embodiments, Figure 8As shown, the storage box 4 may include a box body 41, and the box body 41 may form a storage cavity 42 with openings at both ends. The storage cavity 42 may be used to place pre-thawed items, and the lower end opening of the storage cavity 42 may be used to communicate with the thawing through hole 15 (such as Figure 5 As shown), and pre-thawed items can be placed into the storage cavity 42 through the upper end opening of the storage cavity 42.

[0081] Or, if Fig. 9 As shown, the storage box 4 may include a box body 41 and at least one partition 43. The partition 43 may be installed in the box body 41 and may divide the box body 41 into a plurality of storage chambers 42 distributed along a first straight line direction. The plurality of storage chambers 42 may store one or more different pre-thawed items, and the lower end openings of the plurality of storage chambers 42 may be connected to the thawing through hole 15 (such as Figure 5 As shown), the pre-thawed items can enter the second accommodating chamber 14 for thawing when the thawing through hole 15 is in the open state.

[0082] It should be noted that, in the above embodiment, the first straight line direction may be perpendicular to the up-down direction or intersect with the up-down direction. Taking the first straight line direction being perpendicular to the up-down direction as an example, the first straight line direction may be the front-back direction or the left-right direction.

[0083] In the embodiment of the present application, taking the first straight line direction as the front-to-back direction as an example, correspondingly, the second straight line direction may be the left-to-right direction.

[0084] The box body 41 may be a frame structure or a plate structure, and is not limited to any structure as long as it can accommodate pre-thawed items.

[0085] In the box body 41, the number of the storage chambers 42 can be one more than the number of the partitions 43. If the number of the partitions 43 is one, the number of the storage chambers 42 can be two. If the number of the partitions 43 is two, the number of the storage chambers 42 can be three, and so on.

[0086] In some embodiments, Figure 5 and Fig.10 As shown, the refrigerator may further include a second door valve assembly 6, which may include a second door panel 61 and a second driving member 62. Exemplarily, the second door panel 61 may be installed near the lower end opening of the storage box 4, and the second driving member 62 may be used to drive the second door panel 61 to open or close the lower end opening of the storage box 4.

[0087] It should be noted that, when the second door panel 61 and the first door panel 33 are sequentially installed at the storage box 4 and the thawing through hole 15, when the second door panel 61 opens the lower end opening of the storage box 4, and the first door panel 33 opens the upper end or the lower end of the thawing through hole 15, the thawing through hole 15 can be in an open state. When at least one of the first door panel 33 or the second door panel 61 is in a closed state, the thawing through hole 15 is in a closed state.

[0088] For the second door panel 61, the second door panel 61 can be hingedly installed with the lower end of the box body 41, and the second driving member 62 can be connected with the hinge axis of the second door panel 61 through a gear, a transmission belt or a transmission shaft, so that the second driving member 62 can drive the second door panel 61 to rotate downward to open or close the lower end opening of the storage cavity 42.

[0089] Alternatively, the second door panel 61 may also translate at the lower end of the storage cavity 42 to open or close the lower end of the storage cavity 42 .

[0090] For example, Fig.10 As shown, the second gate valve assembly 6 may further include a roller member 63 and a plurality of transmission gears 64, and the second driving member 62 may be connected to the roller member 63 through a gear set formed by the plurality of transmission gears 64, so that the second driving member 62 may drive the roller member 63 to rotate forward or reversely. The second door panel 61 may extend along the first straight line direction, and one end of the second door panel 61 along the first straight line direction may be connected to the roller member 63. Driven by the second driving member 62, the second door panel 61 may be wound around the roller member 63 and open the storage chamber 42 (as shown in FIG. 4 ). Figure 8 shown).

[0091] The roller member 63 may be disposed at one end of the box body 41 along the first straight line direction, and the axial direction of the roller member 63 may intersect or be perpendicular to the first straight line direction. The second door panel member 61 may be a rollable structure formed by connecting a plurality of strip structures, similar to a rolling door structure or a watch chain structure, or the second door panel member 61 may be made of a rollable material such as a flexible metal sheet, a rubber sheet or a plastic sheet.

[0092] When the roller member 63 and the second driving member 62 are connected by a gear set, the second driving member 62 and the roller member 63 can be connected by a reduction gear set to provide a larger torque at the roller member 63. In other embodiments, the second driving member 62 can also drive the roller member 63 to rotate by means of a transmission belt or a transmission shaft.

[0093] Based on this, when installing the second door panel 61, Fig.11As shown, the second door valve assembly 6 may further include a guide rail portion 65, which may be extended along a first straight line direction (such as a front-to-back direction). The guide rail portion 65 may be distributed on the left and right sides of the lower end of the storage box along a left-right direction (such as a second straight line direction), so that the left end of the second door panel 61 of the rollable plate structure may be inserted into the left guide rail portion 65, and the right end of the second door panel 61 may be inserted into the right guide rail portion 65, so that the second door panel 61 may move between the two guide rail portions 65 in the front-to-back direction.

[0094] In this way, the second gate valve assembly 6 can have an open motion state and a closed motion state.

[0095] When the second gate valve assembly 6 is in an open movement state, the second driving member 62 can drive the roller member 63 to rotate, so that the second door panel member 61 can wrap around the roller member 63 along the circumference of the roller member 63, and the end of the second door panel member 61 away from the roller member 63 along the first straight line direction can open the lower end opening of the storage chamber 42.

[0096] When the second gate valve assembly 6 is in a closed movement state, the second driving member 62 can drive the roller member 63 to rotate, so that the second door panel member 61 on the coiled roller member 63 moves away from the roller member 63 along the first straight line direction, thereby causing the second door panel member 61 to move in the opposite direction and close the lower end opening of the storage chamber 42.

[0097] In the case where the plurality of storage cavities 42 are distributed along the first straight line direction, the second door valve assembly 6 provided with the above structure can sequentially open the lower end openings of the plurality of storage cavities 42 along the first straight line direction, or the second door panel 61 can sequentially close the lower end openings of the plurality of storage cavities 42 in the reverse direction along the first straight line direction. In this way, the plurality of storage cavities 42 can be sequentially opened along the first straight line direction, so as to facilitate sequential thawing of the pre-thawed items in different storage cavities 42.

[0098] It should be noted that the guide rail portion 65 can be a separate guide rail structure extending along the first straight direction, and the two guide rails can be installed on opposite sides of the lower end of the box body 41 along the second straight direction for plugging the second door panel 61 .

[0099] Alternatively, the guide rail portion 65 may also be a groove-shaped structure, and a guide rail groove structure may be provided on opposite sides of the lower end of the box body 41 along the second straight line direction, for inserting and guiding the second door panel 61. Alternatively, a guide rail portion 65 of a guide rail groove structure may be formed at the connection position between the lower edge of the box body 41 and the upper edge of the funnel member 5, for inserting and guiding the second door panel 61, which is not limited thereto.

[0100] In some embodiments, Fig.12 The refrigerator 100 may further include a plurality of first sensors 71, referring to Fig. 9A plurality of first sensors 71 may be arranged corresponding to a plurality of storage chambers 42, and a first sensor 71 may be installed close to a storage chamber 42, so that the first sensor 71 can detect whether the lower end opening of the corresponding storage chamber 42 is in an open state.

[0101] The first sensor 71 may be a pressure sensor or a laser sensor. For example, the first sensor 71 is a pressure sensor. At the lower end of the corresponding storage cavity 42, when the second door panel 61 fully opens the lower end opening of the storage cavity 42, the second door panel 61 may press the corresponding pressure sensor in the up-down direction or the left-right direction. When the second door panel 61 fully opens the corresponding storage cavity 42 (or opens to a preset position), the pressure end of the corresponding first sensor 71 is released (not subject to pressure) and sends a first opening state signal.

[0102] Based on this, combined Fig.12 The refrigerator 100 may further include a controller 72, which may be connected to the second drive member 62 and the first sensor 71. After the controller 72 receives the first opening state signal corresponding to the storage cavity 42, the controller 72 may control the second drive member 62 to stop rotating, thereby preventing the second drive member 62 from continuously adding two storage cavities 42 (such as Fig. 9 ) to the second accommodating chamber 14 (as shown) Figure 5 shown).

[0103] In some embodiments, Fig.12 As shown, the refrigerator 100 may further include a second sensor 73, Figure 5 The second sensor 73 can be arranged at the thawing shelf 16, and along the up-down direction, the second sensor 73 can be located below the thawing through hole 15. Alternatively, when a tray 18 is provided on the thawing shelf 16, the second sensor 73 can be installed between the thawing shelf 16 and the tray 18, or the second sensor 73 can be installed in the tray 18.

[0104] The second sensor 73 may be a pressure sensor or a laser sensor. For example, if the second sensor 73 is a pressure sensor, when the pre-thawed item is on the thawing shelf 16, the pressure acting on the pressure sensor may cause the second sensor 73 to output a second open state signal indicating that the first door panel 33 is open. If the second sensor 73 is a laser sensor, when the pre-thawed item is on the thawing shelf 16, the position of the laser sensor may be adjusted so that its beam is blocked by the pre-thawed item. At this time, the second sensor 73 may also output a second open state signal indicating that the first door panel 33 is open.

[0105] Combination Fig.12The refrigerator 100 may further include a signal prompter 74. The controller 72 may be connected to the second sensor 73 and the signal prompter 74. When the controller 72 receives the second start-up state signal, the controller 72 may start the thawing timer state. When the duration of the thawing timer state is greater than or equal to the first preset duration (which may be preset at the factory or may be adjusted by the user), the controller may send a prompt signal through the signal prompter to remind the user that the pre-thawed items have been thawed.

[0106] Exemplarily, the signal indicator 74 may include a yellow indicator light, a green indicator light, a red indicator light, and an orange indicator light.

[0107] When the pre-thawed articles are placed in the tray 18, the controller 72 can continue to receive the second open state signal. In this way, the controller 72 can control the yellow indicator light of the signal prompter 74 to light up to remind the user that the thawing operation is in progress.

[0108] When the pre-thawed items in the tray 18 are completely thawed after a first preset time, the controller 72 can control the green indicator light of the signal prompter 74 to light up to remind the user to take away the thawed items in time.

[0109] When the thawed items in the tray 18 have not been removed after the second preset time, the controller 72 can still continue to receive the second open state signal. In this way, the controller 72 can control the red indicator light of the signal prompter 74 to light up to remind the user that the thawed items have been stored for too long and please pay attention.

[0110] Along the first straight line direction, when a first sensor close to the second driving member 62 sends a corresponding first open state signal, and the corresponding pre-thawed items have been thawed after a first preset time, the controller 72 can control the orange indicator light of the signal prompter 74 to light up to remind the user that all pre-thawed items in the storage chamber 42 have been thawed and need to be reset and put in the next round of frozen items or pre-thawed items.

[0111] It should be noted that, combined with Fig.12 The controller 72 can also be connected to the first driving member 32. When the controller 72 receives a new round of second opening state signal, it indicates that the pre-thawed object has entered the second accommodating chamber 14 (such as the thawing through hole 15). Figure 5 Then, the controller 72 can control the first driving member 32 to rotate in the opposite direction, so that the first door panel member 33 can move in the opposite direction to close the thawing through hole 15, thereby preventing the exchange flow of cold air between the first accommodating chamber 13 and the second accommodating chamber 14.

[0112] Continue to refer to Fig.12The controller 72 can also be connected to the second drive member 62 to store multiple storage chambers 42 (such as Fig. 9 The controller 72 can control the second driving member 62 to drive the second door panel member 61 (as shown in FIG. Fig.11 The storage chambers 42 are opened sequentially along the first straight line direction.

[0113] When one of the first sensors 71 sends a corresponding first opening state signal, the controller 72 can receive the first opening state signal and control the second driving member 62 to stop, so as to prevent the second door panel 61 from opening the next storage chamber 42 along the first straight line. When the second sensor 73 stops sending the second opening state signal, that is, the thawed items have been taken away, the controller 72 can control the second driving member 62 to continue rotating to open the next storage chamber 42.

[0114] When the first sensor 71 at the last storage cavity 42 (i.e., the storage cavity 42 closest to the second driving member 62) sends a first open state signal, and the second sensor 73 sends a second open state signal, the controller 72 can control the second driving member 62 to stop rotating, and then the user can manually reset it to make the second driving member 62 rotate in the opposite direction and close all the storage cavities 42.

[0115] Alternatively, after the third preset time period, the controller 72 may control the second driving member 62 to rotate in the opposite direction and close all the storage chambers 42 .

[0116] It should be noted that, in the embodiment of the present application, the first door panel 33 can also be installed separately at the thawing through hole 15 to manually open or close the thawing through hole 15. The corresponding second door panel 61 can also be installed separately at the lower end opening of the storage chamber 42 so that the user can manually open or close the thawing through hole 15, which is not limited to this.

[0117] The first door valve assembly 3 and the second door valve assembly 6 can be regarded as independent components or as a part of the structure of the refrigerator 100. Correspondingly, the first door valve assembly 3 can also be a part of the box body 1, and correspondingly, the second door valve assembly 6 can also be regarded as a part of the storage box 4, which is not limited.
