[0040] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] In related technologies, if users place unripe fruit inside the refrigerator, over time, the surface of some fruit may suffer damage such as chilling injury due to the low temperature. In other words, the fruit is damaged before it is ripe, thus affecting its edibility. Therefore, the aforementioned refrigerator is not suitable for storing unripe fruit, resulting in lower overall refrigerator performance.

[0046] Based on this, this application provides a drawer device and a refrigeration appliance. By integrating a ripening module into the drawer device, unripe fruit placed inside the drawer device can ripen faster, making it easier for users to eat the fruit and thus improving the performance of the refrigeration appliance.

[0047] It should be noted that the refrigeration appliance provided in this embodiment can be a refrigerator or an ice bar. No specific limitations are made on the type of refrigeration appliance provided in this embodiment.

[0048] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0049] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the drawer device provided in the embodiments of this application. Figure 2 This is an exploded view of a drawer device provided in an embodiment of this application. As shown in the figure, this embodiment provides a drawer device 10, including a drawer body 1 and a cover 2. The top of the drawer body 1 is open; the cover 2 is disposed on the top of the drawer body 1, forming a storage cavity 3 with the drawer body 1. The storage cavity 3 can store fruits, vegetables, and other food products.

[0050] Since the refrigeration appliances in the related technologies cannot ripen the fruit, thus affecting the user's consumption of the fruit, in order to overcome this defect, the drawer device 10 provided in this embodiment also includes a ripening module 4. The ripening module 4 is disposed in the storage cavity 3. The ripening module 4 is used to emit ripening light that shines toward the bottom wall of the storage cavity 3. The ripening light is used to promote photosynthesis of the fruit stored in the storage cavity 3.

[0051] Therefore, by irradiating ripening light, the fruit located in the storage chamber can decompose chlorophyll and increase the synthesis of related pigments, inducing the appearance of ethylene peaks. In this way, a certain ripening effect can be achieved, allowing the fruit to ripen faster and be consumed by the user, improving the convenience of consuming the fruit and thus improving the performance of the refrigeration appliance.

[0052] It should be noted that the ripening light mentioned above can be blue light, red light, or ultraviolet light. Specifically, blue light has a wavelength greater than or equal to 450 nanometers and less than 495 nanometers; blue light can promote photosynthesis in plants, increasing the sugar and nutrient content in fruits. Red light has a wavelength greater than or equal to 620 nanometers and less than 700 nanometers; irradiation with red light can activate phytochromes in plants, thereby promoting the synthesis and action of ethylene. UV light has a wavelength greater than or equal to 100 nanometers and less than or equal to 400 nanometers; UV light can promote the production of plant hormones and accelerate the ripening process of fruits.

[0053] Since red light has a significant ripening effect on most fruits, in this embodiment, the ripening module 4 emits red light that shines towards the bottom wall of the storage cavity 3. This allows the fruit stored in the storage cavity 3 to be irradiated with red light, inducing the decomposition of chlorophyll within the fruit and increasing the synthesis of related pigments, inducing the appearance of the ethylene peak, and thus achieving a certain ripening effect.

[0054] Please combine Figures 3 to 5 , Figure 3This is a three-dimensional structural diagram of a portion of the ripening module in the drawer device provided in an embodiment of this application. Figure 4 for Figure 3 A structural diagram from another perspective. Figure 5 This is a schematic diagram of the light-emitting component in the drawer device provided in this application embodiment. As shown, in order to fix the ripening module 4 and to make the ripening module 4 emit red light, in some embodiments, the ripening module 4 includes a mounting frame 41 and a light-emitting component 42. The mounting frame 41 is detachably connected to the cover 2, and the light-emitting component 42 is detachably connected to the mounting frame 41. The light-emitting component 42 has a plurality of first LED beads 421, which emit red light that illuminates the bottom wall of the storage cavity 3. Thus, the red light emitted by the plurality of first LED beads 421 can irradiate the fruit stored in the storage cavity 3 to ripen it.

[0055] It should be noted that the first lamp bead 421 mentioned above is an LED lamp bead. No specific restrictions are placed on the type of the first lamp bead 421 here.

[0056] Please combine Figure 6 , Figure 6 This is a three-dimensional structural diagram of the mounting bracket in the drawer device provided in the embodiments of this application. As shown in the figure, in some specific embodiments, the mounting frame 41 includes a frame body 411 and a wire part 412. The frame body 411 is detachably connected to the cover 2. The wire part 412 is connected to the frame body 411. A mounting cavity 4111 is formed on the frame body 411. A wire groove 4121 is formed on the wire part 412. The cavity sidewall of the mounting cavity 4111 has a wire hole 4112 that connects the mounting cavity 4111 and the wire groove 4121. The light-emitting component 42 also includes a circuit board 422, a terminal block 423, and a connecting wire 424. The circuit board 422 is disposed in the mounting cavity 4111 and detachably connected to the frame body 411. The terminal block 423 is disposed on the circuit board 422. One end of the connecting wire 424 is connected to the terminal block 423, and the other end of the connecting wire 424 passes through the wire hole 4112 and extends into the wire groove 4121. A plurality of first lamp beads 421 are disposed on the circuit board 422, and the terminal block 423 is located on one side of the plurality of first lamp beads 421.

[0057] It should be noted that a second LED 425 can also be installed on the circuit board 422. The second LED 425 is used to emit light after the door of the refrigeration appliance is opened. Generally, the light emitted by the second LED 425 is white light. Here, there is no specific limitation on the type of the second LED 425.

[0058] The connection between the frame body 411 and the cover 2 can be achieved through fasteners or snap-fit. In this specific embodiment, the frame body 411 and the cover 2 are detachably connected via fasteners. Specifically, the wire guide 412 and the cover 2 are detachably connected together via fasteners. The wire guide 412 has a connecting hole 4122 that penetrates the bottom wall of the wire guide groove 4121. Threaded fasteners such as screws can pass through the connecting hole 4122 and the cover 2, thus detachably connecting the wire guide 412 and the cover 2.

[0059] Furthermore, in order to improve the connection efficiency between the frame body 411 and the cover 2, a positioning structure 5 can be provided between the frame body 411 and the cover 2. The positioning structure 5 is used to limit the relative position between the mounting frame 41 and the cover 2.

[0060] Specifically, the positioning structure 5 includes a positioning protrusion 51, which is disposed on one of the frame body 411 and the cover 2, and the other of the frame body 411 and the cover 2 is provided with a positioning hole for the positioning protrusion 51 to be inserted.

[0061] It is understandable that if the positioning hole is opened on the frame body 411, liquids in the storage cavity 3 may enter the mounting cavity 4111 through the positioning hole, which may cause corrosion to the light-emitting component 42 located in the mounting cavity 4111. In order to avoid this phenomenon to a certain extent, in the specific implementation of this embodiment, the positioning protrusion 51 is provided on the frame body 411, and the positioning hole is opened on the cover 2.

[0062] Of course, the positioning hole can be a through hole or a countersunk hole. When the positioning hole is a countersunk hole, the positioning hole can also be made on the frame body 411.

[0063] Please see Figure 5 In this embodiment, the circuit board 422 is rectangular. Therefore, in order to reduce the volume occupied by the ripening module 4 and increase the usable space for food in the storage cavity 3, the shape of the mounting cavity 4111 and the outline shape of the frame body 411 can be adapted to the shape of the circuit board 422. That is, the mounting cavity 4111 is a rectangular cavity, and the outline shape of the frame body 411 is also close to a rectangle. In other words, both the mounting cavity 4111 and the frame body 411 have two extending directions: one along the length direction of the circuit board 422 and the other along the width direction of the circuit board 422.

[0064] Regarding the cooperation between the aforementioned positioning protrusions 51 and positioning holes, the more positioning protrusions 51 there are, the higher the positioning efficiency between the mounting bracket 41 and the cover 2. Therefore, in the specific implementation of this embodiment, multiple positioning protrusions 51 can be provided, such as two in this embodiment, with the two positioning protrusions 51 arranged at intervals along the width direction of the circuit board 422. Here, there is no specific limitation on the number of positioning protrusions 51.

[0065] It should be noted that since the mounting frame 41 is made of plastic material, such as high-impact polystyrene, the mounting frame 41 itself is not light-transmitting. In this case, if the light emitted by the first LED 421 is to illuminate the fruit located in the storage cavity 3, the opening of the mounting cavity 4111 needs to be set downwards.

[0066] Meanwhile, since the connecting wire 424 cannot be directly exposed to the outside, the opening of the wire groove 4121 needs to be set upwards so that the light-emitting component 42 can be kept working normally. That is to say, in the specific implementation of this embodiment, the opening of the mounting cavity 4111 faces the opposite direction to the opening of the wire groove 4121.

[0067] Furthermore, it is understood that since the connecting wire 424 needs to be electrically connected to the power supply located at the rear of the cooling appliance, at least one section of the wire groove 4121 should extend in the front-to-back direction. That is, in this embodiment, a portion of the wire groove 4121 should extend along the width direction of the circuit board 422. For details, please refer to... Figure 3 , Figure 4 and Figure 6 The conductor section 412 includes a first conductor segment 4123 and a second conductor segment 4124 connected together. The first conductor segment 4123 extends along the length direction of the circuit board 422, and one end of the first conductor segment 4123 is connected to the frame body 411. A first conductor groove segment 4125 is formed within the first conductor segment 4123, and the first conductor groove segment 4125 communicates with the conductor hole 4112. The second conductor segment 4124 extends along the width direction of the circuit board 422, and the second conductor segment 4124 is connected to the other end of the first conductor segment 4123. A second conductor groove segment 4126 is formed on the second conductor segment 4124, communicating with the first conductor groove segment 4125. The first conductor groove segment 4125 and the second conductor groove segment 4126 form the aforementioned conductor groove 4121. It should be noted that the length direction of the circuit board 422 is... Figure 5 The x-axis direction is consistent with the x-axis direction, and the width direction of circuit board 422 is consistent with the x-axis direction. Figure 5 The yy axis directions are consistent.

[0068] The connecting hole 4122 is located at the junction of the first conductor segment 4123 and the second conductor segment 4124.

[0069] Of course, forming the mounting cavity 4111 on the frame body 411 and the wire groove 4121 on the wire section 412 will reduce the structural strength of the mounting frame 41. Therefore, in order to improve the structural strength of the mounting frame 41, a first reinforcing plate 4113 can be provided on the cavity sidewall of the mounting cavity 4111, and a second reinforcing plate 4127 can be provided on the groove sidewall of the wire groove 4121. In this way, the structural strength of the mounting frame 41 can be improved, thereby extending the service life of the mounting frame 41. Here, the shape of the first reinforcing plate 4113 and the second reinforcing plate 4127 is not specifically limited.

[0070] As described above, the circuit board 422 and the frame body 411 are detachably connected. In this embodiment, the detachable connection between the circuit board 422 and the frame body 411 can be a snap-fit ​​connection. Specifically, a first latch 4114 is provided on the bottom wall of the mounting cavity 4111. The first latch 4114 includes a support connecting part 4115 connected to the bottom wall of the mounting cavity 4111. A first latching protrusion 4116 is connected to the bottom end of the support connecting part 4115. The first latching protrusion 4116 abuts against the bottom end of the circuit board 422 to achieve a snap-fit ​​connection between the circuit board 422 and the frame body 411. Of course, in other embodiments, the first latch 4114 can also be of other shapes. Here, the shape of the first latch 4114 is not specifically limited.

[0071] To improve the reliability of the connection between the circuit board 422 and the frame body 411, the aforementioned first latch 4114 can be configured in multiple ways, such as... Figure 6 As shown, in this embodiment, the first latches 4114 can be arranged in two rows along the length of the circuit board 422, and each row of first latches 4114 includes two first latches 4114 spaced apart along the width of the circuit board 422. It should be noted that in other embodiments, the number of first latches 4114 can be more, such as six or eight. Here, there is no specific limitation on the number of first latches 4114.

[0072] Furthermore, the connection between the light-emitting component 42 and the frame body 411 also includes the connection between the wiring terminal 423 and the frame body 411. Therefore, in some specific embodiments, on the side of the first buckle 4114 near the wire hole 4112, two plug-in portions 4117 spaced apart along the width direction of the circuit board 422 can be provided on the bottom wall of the mounting cavity 4111. The two plug-in portions 4117 are plugged into the wiring terminal 423, thus realizing the connection between the wiring terminal 423 and the frame body 411.

[0073] To improve the ripening effect of the ripening module 4, the red light emitted by the multiple first LED beads 421 needs to be relatively uniform. Therefore, in some embodiments, the multiple first LED beads 421 include multiple rows of LED bead groups evenly spaced along a first direction, and each row of LED bead groups includes multiple first LED beads 421 spaced along a second direction; wherein, the first direction is perpendicular to the second direction. In this way, by restricting the arrangement of the multiple first LED beads 421, the uniformity of the red light emitted by the light-emitting component 42 can be improved, so that the ripening effect of the ripening module 4 is better.

[0074] Please combine Figure 5 The first direction can be consistent with the length direction of the circuit board 422, and the second direction can be consistent with the width direction of the circuit board 422.

[0075] Please combine Figure 7 , Figure 7 This is a schematic diagram of a partial structure of the drawer device provided in an embodiment of this application. In some embodiments, the plurality of first LED beads 421 include an odd number of rows of LED bead groups, each row of LED bead groups including an odd number of first LED beads 421; wherein, the cover 2 has a mounting surface 21 disposed facing the bottom wall of the storage cavity 3, the mounting surface 21 forming the top wall of the storage cavity 3, and the orthographic projection area of ​​the first LED bead 421 located at the center of the plurality of first LED beads 421 on the mounting surface 21 covers the center of the mounting surface 21. In this way, the position of the first LED bead 421 located at the center corresponds to the position of the center of the mounting surface 21, thereby further improving the uniformity of illumination and improving the ripening effect of the ripening module 4.

[0076] In the specific implementation of this embodiment, please refer to... Figure 5 The circuit board 422 has three rows of LED groups, each row of LED groups including three first LEDs 421. Here, there is no specific limit to the number of first LEDs 421.

[0077] It is understandable that if the circuit board 422, terminal block 423, first LED bead 421 and second LED bead 425 are exposed, liquid will inevitably form in the storage cavity 3. The liquid will cause excessive or insufficient corrosion to the above-mentioned components, which may affect the normal light emission of the light-emitting component 42. Therefore, it is necessary to set up corresponding structural components to protect the light-emitting component 42. Based on this, the ripening module 4 in this embodiment also includes a protective cover 43. The protective cover 43 is detachably connected to the frame body 411. The protective cover 43 and the frame body 411 enclose a light-emitting cavity that accommodates the circuit board 422. The protective cover 43 is made of light-transmitting material.

[0078] Specifically, the visible light transmittance of the protective cover 43 is greater than or equal to 90%, and the protective cover 43 can be made of general-purpose polystyrene. No specific restrictions are placed on the material of the protective cover 43.

[0079] Please combine Figure 8 , Figure 8 This is a three-dimensional schematic diagram of the protective cover in the drawer device provided in this application embodiment. As shown in the figure, the connection between the protective cover 43 and the frame body 411 can also be achieved by snap-fit. By using a snap-fit ​​connection method, the connection efficiency between the protective cover 43 and the frame body 411 can be relatively high.

[0080] Since the protective cover 43 is connected to the frame body 411, the outline shape of the protective cover 43 is adapted to the shape of the mounting cavity 4111. Regarding the snap-fit ​​method between the protective cover 43 and the frame body 411, multiple spaced-apart second buckles 44 can be provided around the periphery of the protective cover 43, and multiple spaced-apart second protrusions 4118 can be provided on the cavity sidewall of the mounting cavity 4111. Each of the multiple second protrusions 4118 corresponds one-to-one with a single second buckle 44, and the shape of the second buckle 44 can be the same as the shape of the first buckle 4114 described above. Here, no specific limitation is placed on the shape of the second buckle 44.

[0081] Furthermore, the second latching protrusion 4118 is a protrusion that protrudes from the side wall of the mounting cavity 4111, and the top of the protrusion is a latching surface that engages with the second latch 44.

[0082] In order to improve the engagement efficiency between the second latch 4118 and the second buckle 44, the deformation of the second latch 4118 can be increased. Specifically, a deformation cavity 4119 can be provided on the second latch 4118. In this way, the engagement efficiency between the second latch 4118 and the second buckle 44 can be improved, the assembly efficiency of the ripening module 4 can be improved, and the assembly efficiency of the drawer device 10 provided in this embodiment can be improved.

[0083] It should be noted that when assembling the drawer device 10 provided in this embodiment, the light-emitting component 42 should be assembled with the mounting bracket 41 first, then the protective cover 43 should be assembled with the mounting bracket 41, and finally the ripening module 4 should be installed on the cover 2.

[0084] Taking certain fruits, such as avocados, as an example, during the experiment, it was found that when the average light intensity received by the bottom wall of storage cavity 3 was greater than or equal to 45 micromoles per square meter per second, and the light intensity received by the center of the bottom wall of storage cavity 3 was greater than or equal to 75 micromoles per square meter per second, after storing avocados in storage cavity 3 for two days, the sweetness of avocados increased significantly and the hardness decreased significantly. Specifically, the sweetness increased by 54.55% and the hardness decreased by 74%.

[0085] Therefore, in the specific embodiment of this example, the average light intensity received by the bottom wall of the storage cavity 3 is greater than or equal to 45 micromoles per square meter per second, and the light intensity received by the center of the bottom wall of the storage cavity 3 is greater than or equal to 75 micromoles per square meter per second. This results in a better ripening effect for some fruits using the ripening module 4.

[0086] For example, the average light intensity received by the bottom wall of storage cavity 3 can be 45 μmol / m². 2 / s, 46μmol / m 2 / s, 47μmol / m 2 / s, 48μmol / m 2 / s, 49μmol / m 2 / s, 50μmol / m 2 / s, etc.; the light intensity received at the center of the bottom wall of storage cavity 3 can be 75 μmol / m 2 / s, 76μmol / m 2 / s, 77μmol / m 2 / s, 78μmol / m 2 / s, 79μmol / m 2 / s, 80μmol / m 2 / s, etc. Here, no specific restrictions are placed on the average light intensity received by the bottom wall of the storage cavity 3 or the light intensity received by the center of the bottom wall of the storage cavity 3.

[0087] It is understandable that if the depth of the storage cavity 3 is too large, the light energy at the bottom wall of the storage cavity 3 will be low; if the depth of the storage cavity 3 is too small, the illumination will be uneven. Therefore, in this embodiment, the depth of the storage cavity 3 is also limited, specifically, the depth of the storage cavity 3 is greater than or equal to 12 cm and less than or equal to 17 cm.

[0088] For example, the depth of the storage cavity 3 can be 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, etc. Here, there is no specific limitation on the depth of the storage cavity 3.

[0089] Of course, to ensure uniform illumination, the difference in illumination intensity at different locations on the bottom wall of storage cavity 3 can also be limited. Please refer to... Figure 9 , Figure 9This is a schematic diagram of the bottom wall of the storage cavity in the drawer device provided in this application embodiment. The bottom wall of the storage cavity 3 has two opposing first edges 31 and two opposing second edges 32. The two second edges 32 are connected between the ends of the two first edges 31, and the intersection of the first edges 31 and the second edges 32 forms a corner position 33. An edge position 34 is formed between the corner position 33 and the center of the bottom wall of the storage cavity 3. The distance between the edge position 34 and the first edge 31 is equal to the distance between the edge position 34 and the second edge 32. The difference between the light intensity received by the edge position 34 and the light intensity received by the center of the bottom wall of the storage cavity 3 is less than 40%. In this way, the uniformity of light received at all parts of the bottom wall of the storage cavity 3 can be maintained, improving the ripening effect of the ripening module 4.

[0090] For example, the distance between edge position 34 and the first edge 31 and the distance between edge position 34 and the second edge 32 can be 30 mm. Here, there is no specific limitation on the distance between edge position 34 and the first edge 31 and the distance between edge position 34 and the second edge 32.

[0091] Of course, it is understandable that the light intensity at the center of the bottom wall of storage cavity 3 is greater than the light intensity at the edge position 34.
