Detailed Description

A drawer assembly for a refrigerator according to an embodiment of the present invention will be described in detail with reference to fig. 1 to 6. FIG. 1 is a schematic view of a drawer assembly according to one embodiment of the present invention. As shown in fig. 1, the present invention provides a drawer assembly 20 for a refrigerator, which includes a case 100 and a drawer 200. Wherein, the box body 100 has a front opening 110, and the drawer 200 is arranged in the box body 100 in a front-back push-pull manner. The drawer 200 may include a front end plate 210 and a storage box 220 mounted at a rear side of the front end plate 210 for storing articles. After the drawer 200 is completely pushed into the case 100, the front end plate 210 can close the front opening 110 of the case 100, so that a closed space is formed in the drawer 200, and fresh-keeping storage of food is facilitated. The front side of the front end plate 210 may also be provided with a handle 219 to facilitate a user in pulling the drawer 200 open.

The front end plate 210 of the drawer 200 is further provided with an electric component, and the electric component can be a light-emitting component such as an indicator lamp, an adjusting button for adjusting the temperature of the internal space of the drawer 200, a touch screen or a display screen, and the like. For the drawer assembly 20, the power source or the control board providing the power source is not generally provided on the front end plate 210, but is provided on the case 100 or is connected to the main control board of the refrigerator through the case 100. And thus requires electrical components of the front end plate 210 to be connected by cables.

Fig. 2 is a schematic view of the bottom structure of the drawer assembly of fig. 1. Fig. 3 is a schematic view of the drawer 200 of the drawer assembly 20 of fig. 2 pulled forward. As shown in fig. 2 and 3, to facilitate the transmission of power or signals to the power consuming components of the front end panel 210, a transmission cable assembly is also provided on the drawer assembly 20. The transmission cable assembly may include a routing bar 320 and a coil spring cable 310. The front end of the routing rod 320 is fixedly connected to the rear surface of the front end plate 210, and is disposed along the front-rear direction (i.e., a straight rod extending front-rear). A coil spring cable 310 (shaped like the connection line between a landline and a handset in a landline telephone) is fitted over the track rod 320 and has one end fixedly connected to the front end plate 210 and the other end connected to a power or control board to transmit power or signals to the power consuming components on the front end plate 210.

The coil spring cable 310 is configured to be elastically deformed to be elastically expanded when moving forward and backward along with the front end plate 210, i.e., to be elongated when receiving a tensile force, and to be elastically retracted to be original after the tensile force is removed.

As shown in fig. 2, the drawer 200 is pushed into the case 100 while the coil spring cable 310 is in an unstretched state. As shown in fig. 3, the drawer 200 is pulled forward, and the coil spring cable 310 is pulled forward by the front end plate 210 to be elongated. This allows the coil spring cable 310 to be more orderly within the drawer assembly 20, avoiding the need to design longer conventional cables or design complex lead assemblies. In addition, the routing bar 320 may define that the sleeve of the coil spring cable 310 can only flex in a fore-aft direction, avoiding interference with other portions of the drawer assembly 20.

FIG. 4 is an exploded view of the bottom structure of the drawer assembly 20 of FIG. 3; FIG. 5 is an enlarged view of the structure at A of FIG. 4; fig. 6 is a partial schematic view of the structure at B of the front end plate 210 of the drawer 200 of fig. 4. As shown in fig. 4 to 6, in some embodiments of the present invention, the transmission cable assembly further includes a trace shaft 330 extending in a front-rear direction, and a rear end of the trace shaft 330 is mounted to the case 100. The trace bar 320 is a straight tube, which is movably sleeved on the trace shaft 330 back and forth (the rear end is inserted into the trace shaft 330). In the present invention, by inserting the trace shaft 330 into the trace shaft 320, the trace shaft 330 can support not only the trace shaft 320 but also the rear of the coil spring cable 310 when the trace shaft 320 moves forward with the drawer 200.

As shown in fig. 2-4, in some embodiments, to provide better protection for the coil spring cable 310, the transmission cable assembly may further include a protective sleeve 340. The protection sleeve 340 is sleeved on the wiring rod 320, and the coil spring cable 310 is positioned between the protection sleeve 340 and the wiring rod 320.

Preferably, the front end of the protection sleeve 340 is detachably mounted to the front end plate 210 such that it can move forward and backward with the drawer 200. The protective sleeve 340 may be attached to the front end plate 210 by a snap fit or threaded connection. A preferred connection is shown in fig. 5 and 6, where the end of the protection sleeve 340 has two radially outwardly protruding holding protrusions 341, the rear surface of the front end plate 210 is provided with a holding hole 212, the wall of the holding hole 212 is provided with a groove, and two notches 2122 are provided. In the installation, the clamping protrusion 341 is aligned with the notch 2122 and inserted into the clamping hole 212, and then the protection sleeve 340 is rotated to enable the clamping protrusion 341 to be dislocated with the notch 2122, so that the clamping protrusion 341 is finally clamped in the groove in the clamping hole 212. The catching protrusion 341 and the groove may be provided as a transition fit or an interference fit so as to be caught by each other. On this basis, the trace 320 may be threadably connected to the protective sleeve 340. As shown in fig. 4 and 5, the front end of the protection sleeve 340 is provided with an internal thread 342, and the front end of the trace 320 is provided with an external thread 321 (which mates with the internal thread 342) so as to be screwed to the protection sleeve 340. To facilitate the extraction of the coil spring cable 310, the external thread 321 is provided with a relief notch 322 to allow the coil spring cable 310 (the portion with the end straightened) to be extracted through the relief notch 322.

In alternative embodiments not illustrated in the drawings, the protective sleeve 340 may also be secured to the cartridge body 100. Thus, the protective sleeve 340 will not move with it as the drawer 200 moves back and forth.

As shown in fig. 2 to 4, in the above-described embodiment of the present invention, the transmission cable assembly is preferably disposed under the bottom wall of the storage box 220 to avoid affecting the external appearance of the drawer 200.

The transmission cable assembly may be located between the bottom wall of the storage box 220 and the interior bottom wall of the box body 100. Preferably, however, as shown in fig. 4, the bottom wall of the case 100 may be formed with a receiving groove 120 for receiving a transmission cable assembly. The protection sleeve 340 is provided in the receiving groove 120 to be movable forward and backward, and the front end thereof is protruded through the relief through hole 121 at the front of the receiving groove 120. The rear end of the spool 330 is mounted at the rear end of the accommodating groove 120, and can be inserted into a through hole formed at the rear of the accommodating groove 120, for example. A cover plate may be further disposed below the bottom wall of the case 100, and the receiving groove 120 is covered by the cover plate to conceal the transmission cable assembly.

As shown in fig. 7 to 10, the present invention also provides a refrigerator including a cabinet 80 defining a storage space 201 and a drawer assembly 20 according to any of the above embodiments, the drawer assembly 20 being disposed within the storage space 201.

In some embodiments, the refrigerator further includes an air conditioning membrane assembly 30 and an air pump 10. The housing 80 defines a storage space 201 and a compressor compartment 13 therein. The drawer assembly 20 described above is disposed within the storage space 201. Wherein the inner space of the drawer 200 forms an air-conditioned fresh-keeping space, which is a closed space or an approximately closed space.

The refrigerating system of the refrigerator may be a refrigerating cycle system composed of a compressor, a condenser, a throttle device, an evaporator, and the like. The compressor may be mounted within a compressor compartment 13. The evaporator is configured to provide cooling directly or indirectly into the storage space 201. For example, when the refrigerator is a home compression type direct cooling refrigerator, the evaporator may be provided at the inner side of the case 80. When the refrigerator is a domestic compression type air-cooled refrigerator, the refrigerator body 80 is internally provided with an evaporator chamber, the evaporator chamber is communicated with the storage space 201 through an air path system, an evaporator is arranged in the evaporator chamber, and a fan is arranged at an outlet of the evaporator chamber so as to circularly refrigerate the storage space 201.

The modified atmosphere membrane assembly 30 is provided with at least one modified atmosphere membrane 31 and an oxygen-enriched gas collecting cavity, and the surrounding space is communicated with the modified atmosphere fresh-keeping space. The modified atmosphere membrane assembly 30 may be configured such that oxygen in the gas stream in the space surrounding the modified atmosphere membrane assembly 30 permeates through the modified atmosphere membrane 31 more into the oxygen-enriched gas collection chamber than nitrogen. Specifically, the inner side surface of each of the modified atmosphere membranes 31 faces the oxygen-enriched gas collection chamber so that oxygen in the air in the outer space of the modified atmosphere membrane module 30 passes through at least one modified atmosphere membrane 31 more than nitrogen therein into the oxygen-enriched gas collection chamber when the pressure in the oxygen-enriched gas collection chamber is smaller than the pressure in the surrounding space of the modified atmosphere membrane module 30.

The air pump 10 may be disposed in the compressor compartment 13, and the air inlet end of the air pump 10 is connected to the oxygen-enriched gas collecting chamber of the air-conditioning membrane assembly 30 via the pipe 50, so as to pump the gas penetrating into the oxygen-enriched gas collecting chamber out of the storage container.

In this embodiment, the air pump 10 pumps air outwards, so that the pressure of the oxygen-enriched gas collection cavity is smaller than the pressure of the surrounding space of the air-conditioning membrane assembly 30, and further, oxygen in the surrounding space of the air-conditioning membrane assembly 30 can enter the oxygen-enriched gas collection cavity. Because the air-conditioning fresh-keeping space is communicated with the space around the air-conditioning membrane assembly 30, air in the air-conditioning fresh-keeping space can enter the space around the air-conditioning membrane assembly 30, so that oxygen in the air-conditioning fresh-keeping space can enter the oxygen-enriched gas collection cavity, and a nitrogen-enriched and oxygen-depleted gas atmosphere beneficial to food fresh keeping is obtained in the air-conditioning fresh-keeping space.

The refrigerator can form a nitrogen-enriched and oxygen-depleted gas atmosphere in the modified atmosphere fresh-keeping space to be beneficial to food fresh-keeping, and the gas atmosphere reduces the strength of aerobic respiration of fruits and vegetables by reducing the content of oxygen in the fruit and vegetable storage space, ensures the basic respiration function and prevents the fruits and vegetables from carrying out anaerobic respiration, thereby achieving the aim of long-term fresh-keeping of the fruits and vegetables. In addition, the atmosphere also has a large amount of gases such as nitrogen, so that the cooling efficiency of the articles in the air-conditioned fresh-keeping space is not reduced, and fruits and vegetables and the like can be effectively stored. The air pump 10 is arranged in the compressor bin 13, so that the space of the compressor bin 13 can be fully utilized, and other places are not additionally occupied, and therefore, the additional volume of the refrigerator is not increased, and the refrigerator can be compact in structure. The requirements on rigidity and strength of the box 80 and the like are low, and the realization requirements are low, so the cost is low. The refrigerator well solves the technical problems which are required to be solved by the technicians in the field of air-conditioned preservation and are not successfully solved all the time. The refrigerator of the invention has small volume and low noise, and is especially suitable for families and individuals.

In some embodiments of the present invention, the box body 100 may be provided with a plurality of micropores, and the storage space 201 and the modified atmosphere fresh-keeping space are communicated through the plurality of micropores. The micro-holes may also be referred to as air pressure balance holes, each of which may be of the order of millimeters, for example, each having a diameter of 0.1mm to 3mm, preferably 1mm, 1.5mm, etc. The pressure in the modified atmosphere fresh-keeping space can be prevented from being too low by arranging the plurality of micropores, the nitrogen in the modified atmosphere fresh-keeping space can not flow to the large storage space 201 by arranging the plurality of micropores, and even if the nitrogen flows, the nitrogen is very small or even negligible, so that the preservation of foods in the modified atmosphere fresh-keeping space can not be influenced. In some alternative embodiments of the present invention, the case 100 may not have micropores, and even if a large amount of gas such as nitrogen exists in the modified atmosphere fresh-keeping space, the user does not need to take much effort when pulling the drawer 200, and the effort is greatly saved compared with the existing vacuum storage chamber.

In some embodiments of the present invention, the storage space 201 is a refrigerated space, which is stored at a temperature generally between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. Further, the case 80 may further define a refrigerating space 12 and a temperature changing space 27, the refrigerating space 12 is disposed below the storage space 201, and the temperature changing space 27 is disposed between the refrigerating space 12 and the refrigerating space. The temperature in the refrigerated space 12 is typically in the range of-14 to-22 ℃. The temperature change space 27 can be adjusted as needed to store the appropriate food. The compressor compartment 24 is preferably disposed rearwardly and downwardly of the refrigerated space 12. In some alternative embodiments of the present invention, the storage space 201 may also be a freezing space or a temperature-changing space, that is, the temperature range of the storage space 201 may be controlled from-14 ℃ to-22 ℃ or adjusted according to the requirement.

The plurality of second rib plates are arranged at intervals along the transverse direction on the other side surface of the plurality of first rib plates and extend along the longitudinal direction, and the second surface is formed on the side surface of the plurality of second rib plates, which is far away from the first rib plates. The support frame 32 of the present invention ensures continuity of the air flow passage on the one hand, greatly reduces the volume of the support frame 32 on the other hand, and greatly enhances the strength of the support frame 32 by providing a plurality of first ribs spaced apart in the longitudinal direction and extending in the transverse direction and a plurality of second ribs extending in the longitudinal direction on one side surface of the aforementioned plurality of first ribs inside the frame thereof. In addition, the above structure of the support frame 32 ensures that the air-conditioning membrane 31 can be supported sufficiently, and can always maintain good flatness even under the condition that the negative pressure in the oxygen-enriched gas collection cavity is large, thereby ensuring the service life of the air-conditioning membrane assembly 30.

In a further embodiment, the plurality of first ribs may include: a plurality of first narrow ribs and a plurality of first wide ribs. The first wide rib plates are arranged at intervals, and the first narrow rib plates are arranged between two adjacent first wide rib plates. The aforementioned plurality of second ribs may include: the first narrow rib plates and the second wide rib plates are arranged at intervals, and the second narrow rib plates are arranged between two adjacent second wide rib plates. Those skilled in the art will readily appreciate that "wide" and "narrow" herein are relative terms.

In some embodiments, each of the first wide ribs is recessed inwardly from a side surface thereof forming the first surface to form a first groove; each of the second wide ribs is recessed inwardly from its side surface forming the second surface to form a second channel, thereby improving connectivity of its internal lattice structure while ensuring a small thickness (or volume) of the support frame 32.

In a further embodiment, a portion of the surface of each of the first wide ribs facing away from the first surface extends toward the second rib to be flush with the second surface, and is recessed inwardly from the portion of the surface flush with the second surface to form a third groove; the third grooves communicate with the portions where the second grooves intersect to form cross grooves. A part of the surface of at least one second wide rib plate facing away from the second surface extends towards the first rib plate to be level with the first surface, and a fourth groove is formed by inwards sinking the part of the surface level with the first surface; wherein the fourth groove communicates with a portion where the first groove intersects to form a cross groove. In some embodiments of the present invention, to facilitate the flow of the air stream, as shown in FIG. 9, the inner surface of the cover plate portion 26 may extend downwardly beyond a plurality of air guide ribs to direct the air stream from the fan 60 to flow within the receiving cavity and over the outer surface of each of the air regulating membranes 31 of the air regulating membrane assembly 30 facing away from the oxygen-enriched gas collection cavity. The plurality of air guide rib plates can be divided into two groups, including a first group of air guide rib plates and a second group of air guide rib plates which are symmetrically arranged about a plane. Each set of air guide ribs includes a first air guide rib, at least one second air guide rib, and at least one third air guide rib. The first air guide rib extends from the air outlet of the centrifugal fan to one side of the accommodating chamber and extends to one lateral outer side of the air conditioning membrane assembly 30. Each second air guide rib is disposed between two first air guide ribs and between the air conditioning membrane assembly 30 and the centrifugal fan. Each third air guide rib is located at one lateral outer side of the air regulating membrane module 30 to guide the air flow such that the air flow enters the gap between the air regulating membrane module 30 and the bottom surface or the top surface of the accommodating chamber from both lateral sides of the air regulating membrane module 30.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
